- 摘要：OBJECTIVE：To study the m edical insurance budget impact analysis （BIA）guidelines or nomative documents of some European countries ，and to provide the suggestions for the formulation and implementation of medical insurance BIA guidelines in China. METHODS ：Medical insurance BIA guidelines or related documents in European countries such as Ireland ， France，Poland，Belgium and UK were retrieved to summarize and comparatively analyze the general analysis framework and special specification. The formulation of medical insurance BIA guideline in China and the suggestions were put forward. RESULTS & CONCLUSIONS ：The above-mentioned medical insurance BIA guidelines or documents of the five European countries generally study the impact of the cost of health technology on resources within 3-5 years from the perspective of budget holders. The analysis framework of the guidelines or documents is basically the same ，but the guidelines or documents are adjusted according to the characteristics of national health system in terms of the positioning of medical insurance BIA ，the scope of cost data inclusion ， model design ，population subgroup analysis and so on. For example ，Ireland had special requirements on cost data inclusion ， sensitivity analysis and data source ，while France had detailed regulations on medical insurance BIA model ，sensitivity analysis and presentation of medical insurance BIA results. Our country should pay attention to the role of medical insurance BIA in medical and health decision-making ，formulate China ’s medical insurance BIA guidelines to standardize empirical research ，and combine the characteristics of China ’s health system when formulate the guideline. It is suggested that China ’s medical insurance BIA guidelines should at least include research perspective ，research time limit and discount ，reference situation ，target population ， cost，market share ，data source ，uncertainty analysis and other overall framework or basic elements to ensure the smooth operation of medical and health funds.关键词：European countries;Medical insurance;Budget impact analysis;Guidelines;Englightenment

METHODS ：The content analysis method was used to code and measure the policy text of TCM industry in Guangdong-Hong Kong-Macao greater bay area issued by the central government and local government as of April 2020 from the perspective of policy tools. The current development focus and existing problems of the industry were summarized to put forward reasonable suggestion. RESULTS & CONCLUSIONS：A total of 34 relevant policy texts were retrieved ，including 9 at the central government level and 25 at the local government level. In respective of essential policy tool ，the supply-oriented ，demand-oriented and environmental policy tools of TCM industry in Guangdong-Hong Kong-Macao greater bay area accounted for 58.10％，22.86％ and 19.05％，respectively. Among supply-oriented policy tools ，hardware construction accounted for 40.98％，internal communication for 26.23％，quality construction for 22.95％，and international exchange for 9.84％；there was no specific implementation rules and programs for policy tools ，which affect their operability. The demand-oriented policy tools included health service （75.00％），international trade （16.67％），service outsourcing （4.17％）and government subsidies （4.17％）；the use of the latter three approaches limited the openness of the industrial market. The environmental policy tools included target planning （40.00％），access rules （25.00％）， intellectual property （30.00％）and financing support （5.00％），but needed to improve the support of laws and regulations and relevant measures. In respective of the value chain of TCM industry ，34 policy texts showed 4 contents，including platform construction（36.19％），scientific and technological innovation （19.05％），market expansion （23.81％），exchange and cooperation （20.95％）；the lack of scientific and technological innovation and exchange and cooperation limited the standardization ， modernization and internationalization of TCM. It suggested to optimize the supply-oriented policy tools ，improve the operability of policies； pay attention to the demand-oriented and environmental policy tools ， highlight the role of marketization and standardization；pay attention to the integration of basic policy tools and industrial value chain ，and achieve the standardization ， modernization and international development of TCM in Guangdong-Hong Kong-Macao greater bay area.

METHODS ：Each 16 batches of A. dahuricae with and without sulphur-fumigation were selected as samples. Deuterated methanol-deuterium oxide （1 ∶ 0.2，V/V）was used as extraction solvent ，and 1H-NMR metabolomics was used to detect the primary and secondary metabolites in A. dahuricae . In addition ，visual analysis ，principal component analysis （PCA）and t-test were used to compare the component differences of A. dahuricae by two kinds of pretreatment methods. RESULTS ：A total of 19 chemical constituents such as coumarins ，amino acids and sugars were simultaneously detected and identified from two kinds of A. dahuricae . Visual analysis showed that the chemical profiles of the two kinds of A. dahuricae were similar ，but their coumarins and carbohydrates were quite different in 1H-NMR signal intensity. PCA analysis showed that all samples could be divided into two categories according to different treatment methods. The results of t-test showed that the contents of oxypeucedanin ，imperatorin，glucose and sucrose of A. dahuricae were decreased significantly after sulphur fumigation （P＜0.01 or P＜0.001），while the contents of alanine and leucine were significantly increased （P＜0.01 or P＜0.001）. There was no statistical significance in the contents of other 13 kinds of components （P＞0.05）. CONCLUSIONS：There are obvious differences in the 6 chemical compounds of oxypeucedanin ，imperatorin，glucose，sucrose， alanine and leucine in A. dahuricae with and without sulphur-fumigation ，which can be used as chemical markers for the identification of sulphur-fumigated A. dahuricae in the market.关键词：Angelicae dahuricae;Sulphur-fumigation;1H-NMR metabolomics;Chemical markers;Identification

METHODS ：UPLC-MS/MS method was adopted to determine the contents of 6 active components in the intestinal circulatory perfusion fluid. Totally male SD 80 rats were divided into normal group and model group ，with 40 rats in each group. Model group was given isoproterenol hydrochloride （50 mg/kg） subcutaneously to induce MI model；normal group was given constant volume of normalsaline， once a day ， for consecutive 2 days. 24 h after successful molding ，normal group and model group received in-situ intestinal circulatory perfusion experiment. The effects of different concentration s of P. orientale extract（5.0，10.0， 20.0 mg/mL），different intestinal segments （duodenum，jejunum，ileum，colon），P-glycoprotein（P-gp）inhibitors（verapamil） and bile on the intestinal absorption of each constituent were explored. RESULTS ：The linear ranges of concentrations of kaempferol， isokaempferol， vitexin， protocatechuic acid ， kaempferol-3-O-β-D-glucoside and quercetin were 3.15-50.40， 3.21-51.31，1.63-52.43，1.60-50.94，1.31-20.97，8.07-129.25 µg/mL（r＞0.999）. The lower limits of quantification were 7.86， 8.45，6.52，4.00，3.28，16.14 ng/mL，respectively. RSDs of precision ，matrix effect and stability tests were all lower than 11％； the accuracy were 85.64％-107.65％，which were in line with the requirements of biological sample quantification analysis. Except for there was no statistical significance in the absorption of kaempferol absorption in duodenum of model group at different concentrations，absorption of other five constituents in duodenum of normal and model rats increased with the increase of the concentration of active constituents ，and absorption of medium- and/or high- concentration active constituents （except quercetin ）in model group was significantly lower than normal group （P＜0.05）. In normal group ，the absorption of kaempferol was more in jejunum，ileum and colon ，isokaempferol was more in ileum ，vitexin and protocatechuic acid were more in jejunum and ileum ， kaempferin-3-O- β-D-glucoside was more in duodenum ，jejunum and colon ，quercetin was more in colon ；in the model group ，the absorption of Polygonum orientale in jejunum and colon was more ，the absorption of isokaempferol in 4 intestinal segments was little different ，vitexin was mainly absorbed in ileum ，protocatechuic acid and kaempferol- 3-O-β-D-glucoside was mainly absorbed in jejunum ，quercetin was mainly absorbed in duodenum and ileum ；in the same intestine ，the absorption of constituents in the model group was less than normal group. After adding verapamil ，absorption of all constituents in the normal group increased ，but the difference was not statistically significant （P＞0.05）；absorption of kaempferol ，isokaempferol，vitexin，protocatechuic acid and kaempferol- 3-O-β-D-glucoside were all increased significantly in model group （P＜0.05），while there was no statistical significance in the increase of quercetin （P＞0.05）. After the bile flowed into the duodenum ，absorption of protocatechuic acid was increased significantly in normal group （P＜0.05）；absorption of other active constituents were increased significantly in model group，except for isokaempferol and quercetin （P＜0.05）. CONCLUSIONS ：Six active constituents of P. orientale were absorbed in the whole intestine of normal and MI model rats ，and the absorption of above constituents may be enhanced more significantly by P-gp inhibitor and bile under pathological condition.关键词：Myocardial ischemia;Polygonum orientale;Active constituent;Intestinal absorption;Intestinal perfusion;Rat

METHODS ：MN rat model was established by subcutaneous and caudal vein injecting cationic bovine serum albumin + incomplete Freund adjuvant emulsion for 6 weeks. At the 3rd week of modeling ，model rats were randomly divided into model control group ，SZD low-dose and high-dose groups （4，8 g/kg，by total crude drugs ），TPT group （9 mg/kg），low-dose and high-dose of SZD+TPT groups （same dose as single group ），with 10 rats in each group according to 24 h UTP and weight. Another 10 rats withoutmodeling were taken as blank control group. Blank control group was given equal amount of water intragastrically administration groups were given relevant medicine intragastrically，once a day ，for consecutive 4 weeks. The 24 h UTP of rats were detected one day before the last administration；1 h after the la st administration ，blood routine 中indexes（WBC，RBC，PLT），liver func tion indexes （TP，ALB，AST，ALT），blood lipid indexes （TC，TG，HDL-C，LDL-C）， the contents of glucose （GLU），urea nitrogen （BUN）and serum creatinine （Scr）were detected in each group. Uranyl acetate-lead citrate staining was used to observe ultrastructural changes of renal tissue. Immunohistochemical method was used to detect the protein expression of TGF-β1 and HPA- 1 in renal tissue. RESULTS ：Compared with blank control group ，in the model control group，the glomerular podocytes were widely fused or disappeared ，microvilli were formed ，basement membrane was heavily thickened，a large number of electron dense substance was deposited under the epithelium ，TGF-β1 and HPA- 1 positive cells were significantly increased ；24 h UTP ，PLT，the contents of TC ，TG and HDL-C ，the percentage of TGF-β1 and HPA- 1 positive cells were increased significantly ，while RBC ，the contents of TP and ALB were decreased significantly （P＜0.05 or P＜0.01）. Compared with model control group ，above ultrastructural changes of administration groups were improved to different extents ，and TGF-β1 and HPA- 1 positive cells were decreased. The 24 h UTP ，the percentage of TGF-β1 positive cells （except for SZD low-dose group），WBC（except for SZD alone groups and combination groups ），PLT and TC content （except for TPT group ），TG content （except for SZD low-dose alone and its combination group ），the percentage of HPA- 1 positive cells were decreased significantly ； the percentage of TGF-β1 positive cells in SZD high-dose+TPT group as well as the percentage of HPA- 1 positive cells in SZD+TPT groups were significantly lower than TPT group. RBC and GLU content （except for SZD low-dose group and TPT group ），TP and ALB content （except for SZD low-dose group ）were increased significantly ，while the content of GLU in SZD high-dose+TPT group was significantly higher than TPT tablets group （P＜0.05 or P＜0.01）. CONCLUSIONS ：SZD combined with TPT can relieve myelosuppression caused by TPT ，reduce proteinuria of MN model rats and improve pathological damage of renal tissue in rats. Its mechanism is related to the down-regulation of protein expression of TGF-β1 and HPA- 1，and the reduction of TC and TG content in the blood.

METHODS ：Totally 30 male SD rats were divided into sham operation group （normal saline ）， model group （normal saline ），8-OaS low-dose ，medium-dose and high-dose groups （3，10，30 μg/kg），with 6 rats in each group. Except for sham operation group ，other groups were given planter injection of Freund ’s complete adjuvant to induce chronic inflammatory pain model. After successful modeling ，the rats in each group were given corresponding drugs intrathecally ，once a day，for 7 consecutive days. Then Von-Frey filaments were used to detect the planter pain threshold of the rats in each group ；the area under the planter pain threshold curve of each group and the half effective dose （ED50）of 8-OaS were calculated. Another 36 male SD rats were divided into sham operation group （normal saline ），model group （normal saline ）and 8-OaS group （dose of ED50），and the modeling method and administration route were the same as above. Immunofluorescence histochemical staining was used to observe the positive expression of ionized calcium binding adapter molecule 1（Iba-1）and signal molecule phosphorylated p38 mitogen-activated protein kinase （p-p38 MAPK）；Western blotting assay was used to determine the expression of Iba- 1，p-p38 MAPK，IL-1β，IL-6 and TNF-α in spinal dorsal horn of rats. RESULTS：Compared with sham operation group ，plantar pain threshold and area under the curve in model group were reduced significantly （P＜0.01）. Compared with model group ，plantar pain threshold increased significantly after 5，6，7 days of administration in 8-OaS low-dose group （P＜0.05），plantar pain threshold and area under the curve in 8-OaS medium-dose and high-dose groups were increased significantly （P＜0.05 or P＜0.01）. Most of above indexes in each dose group of 8-OaS were signifficantly different ，and ED 50 of 8-OaS was 18.87 μ g/kg. Results of immunohistochemistry staining and Western blotting showed that p-p 38 MAPK was mainly expressed in Iba- 1 positive cells. Compared with sham operation group ，the fluorescence density of Iba- 1 and p-p 38 MAPK in spinal dorsal horn ，the expression of Iba-1，p-p38 MAPK，IL-6，IL-1β and TNF-α were significantly increased in model group（P＜0.05 or P＜0.01）. Compared with model group ，the fluorescence density of Iba- 1 and p-p 38 MAPK in spinal dorsal horn ，the expression of Iba- 1，p-p38 MAPK， IL-6，IL-1β and TNF-α were decreased significantly in 8-OaS group （P＜0.05）. CONCLUSIONS ：Intrathecal administration of 8-OaS can effectively alleviate chronic inflammatory pain in rats. The mechanism may be related to the inhibition of the phosphorylation of p 38 MAPK and the expression of IL- 6，IL-1β and TNF-α.

METHODS ：Totally 200 inpatient medical records were collected from our hospital retrospectively during Jan. 2018-Feb. 2020，and then divided into group A （prophylactic use of magnesium isoglycolate ，50 cases），group B （prophylactic use of magnesium isoglycolate combined with TCM prescriptions ，50 cases），group C （prophylactic use of polyene phosphatidylcholine ，50 cases） and group D （non-prophylactic use of liver-protection drugs ，50 cases）. The effects （total response rate ）of four plans preventing liver damage were evaluated. Pharmacoeconomic evaluation was analyzed by cost-minimization analysis and cost-effectiveness method ， sensitivity analysis was carried out at the same time . RESULTS ：Total response rates of group A ，B，C and D were 94.00％， 96.00％，82.00％ and 72.00％. The total response rates of group A and B had no statistical significance （P＞0.05），but were significantly higher than those of group C and D （P＜0.05）；total response rate of group C was significantly higher than that of group D （P＜0.05）. The costs of groups A ，B，C and D were 1 936.70，2 086.96，1 800.91，2 975.42 yuan. The cost-minimization analysis was used to compare the therapeutic plan of group A and B ，and plan of group A was more economical. The cost-effectiveness method was used to compare therapeutic plan between group C and D ，and the plan of group C was more economical. The cost-effectiveness method was used to compare therapeutic plan between group A and C ，and the cost-effectiveness ratio of 2 groups were 2 060.32 and 2 196.2 3，incremental cost-effectiveness ratio was 1 131.58，and the plan of group A was more economical. Above conclusion were supported by the results of sensitivity analysis. CONCLUSIONS ：The cost-effectiveness of magnesium isoglycyrrhizinate preventing liver damage induced by chemotherapeutic drugs for gastric cancer is better than magnesium isoglycyrrhizinate combined with TCM prescription ， polyene phosphatidylcholine and non-prophylactic use of liver-protecting drugs ，showing economical advantage.关键词：Magnesium isoglycyrrhizina te;Drug-induced liver damage;Gastic cancer;Chemotherapeytic drug;Pharmacoeconomics

METHODS ：Totally 115 patients diagnosed as sepsis complicated with ALI were collected from Jul. 2015 to Nov. 2019 in intensive care unit of our hospital. According to therapy method ，the patients were divided into control group （26 cases），low-dose group （29 cases），medium-dose group（30 cases），high-dose group （30 cases）. The control group received Ulinastatin injection 300 thousands u intravenously ，q8 h， for consecutive 5 days，on the basis of routine treatment. On the basis of control group ，low-dose group additionally received intravenous drip of Xuebijing injection 50 mL，bid，for consecutive 7 days；medium-dose group additionally received intravenous drip of Xuebijing injection 100 mL，bid，for consecutive 7 days；high-dose group additionally received intravenous drip of Xuebijing injection 100 mL，qid，for consecutive 7 days. The serum inflammatory factors （IL-6，TNF-α，CRP），respiratory function indexes （PaO2，PaO2/FiO2，ELWI）and related scores （APACEⅡ score and SOFA score ）were compared among 4 groups before and after treatment ，and mechanical ventilation time ，ICU hospitalization time ，28-day mortality rate and adverse reactions during the treatment were recorded. RESULTS ：Before treatment ，there was no statistical significance in serum inflammatory factors，respiratory function indexes or related scores among 4 groups（P＞0.05）. After treatment ，serum inflammatory factors ， ELWI and related scores of 4 groups were decreased significantly ；the low-dose ，medium-dose and high-dose groups were significantly lower than the control group ；the high-dose group was significantly lower than the low-dose and medium-dose groups （P＜0.05）. PaO 2 and PaO 2/FiO2 of 4 groups were increased significantly ，compared with before treatment ；the low-dose ， medium-dose and high-dose groups were significantly higher than the control group ；the high-dose group was significantly higher than the low-dose and medium-dose groups （P＜0.05）. The mechanical ventilation time and ICU hospitalization time in the low-dose，medium-dose and high-dose groups were significantly shorter than control group （P＜0.05），but there was no statistical significance in above indexes among different doses groups （P＞0.05）. There was no statistical significance in 28-day mortality among 4 groups（P＞0.05），and no serious adverse reactions were found. CONCLUSIONS ：Different doses of Xuebijing injection combined with Ulinastatin injection could effectively decrease the level of serum inflammatory factors in patients with sepsis complicated with ALI ，improve lung function and relieve the degree of organ failure ；after combined with high-dose Xuebijing injection，the therapeutic effect is more obvious and does not affect the treatment safety.关键词：Xuebijing injection;Ulinastatin;Sepsis;Acute lung injury;Doses;Therapeutic efficacy;Safety

Control group was given Oxcarbazepine tablet with initial dose of 8-10 mg/（kg·d），morning and night ，increased by 5-10 mg/（kg·d）each week according to patient ’s condition ，the maximal dose was 45 mg/（kg·d），lasting for 3 months with the lowest effective treatment dose. Based on treatment of control group ，observation group was additionally given Levetiracetam tablet with initial dose of 5-10 mg/（kg·d），morning and night ，increased by 5-10 mg/（kg·d）each week according to the severity of disease，the total dose was not more than 2 000 mg/d，lasting for 3 months with the lowest effective treatment dose. The event-related potential P 300 at Pz site in 2 groups was measured before and after treatment （including the incubation period of N 1， P2，N2 and P 3 waves，amplitude of P 3 wave）. Webster ’s Adult Intelligence Scale [WAIS-RC ，including verbal IQ （VIQ）， performance IQ （PIQ），full scale IQ （FIQ）scores] and Clinical Memory Scale [CMS ，converting to memory quotient （MQ） score] were adopted. The occurrence of ADR was recorded. RESULTS ：Totally 5 patients of control group and 7 patients of observation group fell off. Finally ，a total of 71 patients participated in the entire study （34 cases in control group and 37 cases in observation group ）. Before treatment ，there was no statistical significance in P 300 at Pz site ，WAIS-RC and CMS between 2 groups （P＞0.05）. Compared with before treatment ，incubation period of N 2 and P 3 waves was shortenedsignificantly in 2 groups，and amplitude of P 3 wave wasincreased significantly after treatment （P＜0.05）；VIQ，FIQ and MQ scores were increased significantly （P＜0.05）. The incubation pe riod of P 2 wave was shortened significantly，and PIQ score was increased significantly in observation group （P＜ 0.05）. Compared with control group ，the shortening degree of incubation period of P 2，P3 waves，rising degree of amplitude of P 3 wave and rising degree of VIQ ，PIQ，FIQ，MQ scores were more bigger after treatment in observation （P＜0.05）. In the control group，there was 1 case of slight rash ，1 case of conscious asthenia ；in the observation group ，there was 1 case of nausea and vomiting，1 case of conscious asthenia ，and 1 case of emotional instability ；no serious ADR was found in 2 groups. CONCLUSIONS：Oxcarbazepine combined with levetiracetam can improve cognitive dysfunction in adult patients with temporal lobe epilepsy ，and the treatment effect is significantly better than oxcarbazepine monotherapy.关键词：Oxcarbazepine;Levetiracetam;Temporal lobe epilepsy;Cognitive d ysfunction;Adult

METHODS ：A multidisciplinary collaborative prescription review mode was established in the First Affiliated Hospital of University of Science and Technology of China （called“our hospital ”for short ）. The prescription management group （composed of the president in charge ，the director of pharmacy department ，the director of medical department and the person in charge of pharmacy ，medicine，nursing and administrative management ）was set up under the Pharmaceutical Affairs Management and Drug Treatment Committee ；and then prescription review expert group （be responsible for providing professional technical consultation and final evaluation of prescriptions ）and prescription review working group （be responsible for the initial evaluation of prescriptions ）were set up. According to the Drug Administration Law ，the Law of Licensed Doctors and the Law of Anti-unfair Competition Act and so on ，the Measures for the Supervision and Administration of Drug Purchase ，Sale and Use in our hospital was formulated. The multi-disciplinary collaborative prescription review procedure was established to intervene key monitored drugs prescriptions. The utilization rate of key monitored varieties and prescription reasonability in our hospital were investigated before （Jun. 2019）and after the intervention （Sept. 2019）by the mode. RESULTS ：The multidisciplinary collaborative prescription review mode was established sucessfully. The proportion of key monitored drugs in total drug sales amount decreased from 1.322％ before intervention to 0.735％ after intervention （P＝0.010）. The irrational rate of prescriptions decreased from 46.76％ before intervention to 15.70％ after intervention （P＝0.023）. The main types of irrational prescriptions were inappropriate usage and dosage （18.52％），inappropriate indications（12.50％），inappropriateroute of administration （9.26％）before intervention changed into inappropriate usage and dosage （15.70％）after intervention ； other irrational prescription types had been significantly improved. CONCLUSIONS ： The multidisciplinary collaborative prescription review model shows significant effect on key monitored drugs and reduce irrational use of this variety in the clinic significantly.关键词：Multidisciplinary collaboration prescription review mode;Key monitored drugs;Drug management;Practice

METHODS ：Taking marketing authorization holder （MAH），staff of medical institutions at the second level or above and drug regulatory authorities in the relevant meeting held in Shenzhen in 2018 as objects ，on-the-spot anonymous investigation of “questionnaire star ”was used to collect and analyze the cognition ，attitude（including attitude towards ADR compensation and ADR compensation system ）and behavior of the above-mentioned personnel to ADR compensation. The relevant suggestion was put forward. RESULTS & CONCLUSIONS ：A total of 172 questionnaires were collected （all being valid ）. In term of cognition ，the respondents generally had high awareness of ADR （response rate of ADR concept was 82.0％）. In term of attitude to ADR injury compensation ，100 respondents（58.1％）believed that ADR after medication should be compensated ，and 147 respondents（85.5％）believed that compensation should be made for serious and fatal adverse reactions. In term of attitude to ADR injury compensation system ，respondents thought that ADR damage compensation funds be undertaken by MAH for 131 case times （76.2％）. As for the difficulties in the implementation of ADR compensation ，it was considered that the evaluation of the correlation between adverse reactions and drugs led to the difficulties in the implementation of ADR compensation （143 case times ， 83.1％）；most respondents thought that the first thing to do in the implementation of ADR compensation system was to implement laws and regulations （145 case times ，84.3％）. In term of behavior ，104 respondents（60.5％）had processed costs due to ADR ， most of whom chose self-resolved （85 cases，81.7％）；112 respondents （65.1％） chose to inform medical personnels or pharmacies directly. It is suggested that the relevant departments in Shenzhen should explore and establish ADR injury compensation mechanism in Shenzhen by establishing a public oriented platform and mechanism for ADR science popularization （setting up relevant departments ，supervising the public propaganda of news media ，expanding the public propaganda to the commu nity），exploring and establishing ADR injury compensation mechanism （setting up a special legislative pilot of ADR injury regulations ，setting up ADR injury appraisal committee ），and increasing the investment in ADR testing （fully using of “Internet+”Big Data ，allocating special funds ）.关键词：Shenzhen;Drug practitioners;ADR;Injury compensation;Cognition;Attitude;Behavior
