RESULTS &CONCLUSIONSThere were contradictions and coupling among the state logic， market logic， social logic and professional logic in the use of national negotiation drugs. In the game of multiple logics， the market logic and professional logic tended to be risk-averse， the failed “pressure-type system” of state logic， and the social logic was weakened， which caused the lack of action in the use of national negotiation drugs with the goal of completing performance evaluations in the current medical institutions. Thus， it is suggested to unbundle the invisible policy restrictions on the use of national negotiation drugs， form the pressure and motivation of medical institutions by incentive and constraint mechanisms， respond to the clinical demand by establishing a green procurement channel， and construct the supervision mechanism on the use of national negotiation drugs by social force， etc.， so as to enhance the effect of the national negotiation drugs.关键词：multiple institutional logics;medical institutions;institutional environment;behavioral choices

The classification statistics and evidence-based inquiry were carried out for irrational drug use issues； combined with our hospital’s current implementation of the Anesthesiology Clinical Pathway Medication Standards， the audit rules were set in details， and audit management and communication feedback processes were established. The total number of monthly audited orders， the number of pre-audit pop ups， system interception rate， physician modification rate after system audit， pharmacist audit rate， and reasonable rate of medical orders after refined setting of rules （May-December in 2023） were compared with before setting （April in 2023）； the average medication cost per anesthesia session after refined setting of rules was also compared with before setting （May-December in 2022）.RESULTSIrrational drug use in the anesthesia department mainly included inappropriate indications， inappropriate administration routes， inappropriate usage and dosage， inappropriate compatibility， medication problems in special populations， and improper medication during the perioperative period. After the refinement of the rules， the number of pre-audit pop ups in the anesthesia department significantly decreased over time， and gradually reached a stable state after continuous improvement. Compared with before setting， the system interception rate after the refinement of rules （P＜0.001）， physician modification rate after system audit （P＜0.001） both increased significantly， while the pharmacist audit rate significantly decreased （P＜0.001）. There was a linear trend between the reasonable rate of medical orders and the month from May to December in 2023 （P＜0.05）. Compared with before the setting， the average medication cost of anesthesia per session decreased from 720.72 yuan to 528.21 yuan， with a decrease of 26.71%.CONCLUSIONSBased on evidence-based reference， refining pre-audit rules for anesthesia prescriptions can significantly improve the quality of prescription examination， promote rational drug use， and save patient’s medical expenses.关键词：anesthesia department;evidence-based reference;audit rules;rational drug use

The mice of SCD groups were fed with SCD， and other groups were given HFD for consecutive 24 weeks to establish NASH model. Since 17th week， the mice in each drug group were given corresponding drug solutions intragastrically， once a day， for 8 consecutive weeks. After the last medication， the body weight and liver weight of mice were determined， and liver indexes were calculated. The contents of total cholesterol （TC） and triglyceride （TG） in liver tissue， the serum contents of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， interleukin-1β （IL-1β） and IL-18 were all determined. Hepatic steatosis and fibrosis were observed， and hepatic lipid droplets were located. The expressions of IL-18 and IL-1β mRNA， inflammation-related proteins （IL-1β， cleaved-IL-1β）， fibrosis-related proteins [collagen Ⅰ （Col-Ⅰ）， α-smooth muscle actin （α-SMA）， connective tissue growth factor （CTGF）]， and pathway-related protein [adenosine monophosphate-activated protein kinase （AMPK）， phosphorylated AMPK （p-AMPK）， Yes-associated protein （YAP）， phosphorylated YAP （p-YAP）] were all determined. HepG2 human liver cancer cells were selected as subjects and divided into control group， oleic acid （OA） group， Sin 50 μmol/L group， Sin 100 μmol/L group， OA+Sin 50 μmol/L group and OA+Sin 100 μmol/L group. After 24 hours of treatment， the accumulation of lipid droplets was observed， and the expressions of pathway-related proteins were detected.RESULTSCompared to HFD group， hepatic steatosis， fibrotic lesions and lipid droplet accumulation were all alleviated in Sin groups； body weight， liver weight， liver indexes， the contents of AST， ALT， IL-1β， IL-18 in serum and TG， TC in liver tissue， the mRNA expressions of IL-1β and IL-18， and the expressions of cleaved-IL-1β and fibrosis-related proteins all decreased significantly （P＜0.01）； the protein expression of IL-1β， and the phosphorylation levels of AMPK and YAP proteins significantly increased （P＜0.01）. Compared with OA group， the lipid droplet accumulation of cells in OA+Sin groups significantly decreased， while the phosphorylation levels of AMPK and YAP proteins significantly increased （P＜0.05）.CONCLUSIONSSin can ameliorate the inflammation， lipid deposition and fibrosis of liver tissue in mice， the mechanism of which may be associated with activating the AMPK signaling pathway and promoting YAP phosphorylation.关键词：sinomenine;AMPK;YAP;inflammatory reaction

The in vitro simulation system for chewable tablets was established by using a texture analyzer and rheometer， and an oral simulation experiment was conducted on chewable tablets. The texture analyzer was used to measure the force required for chewing and simulate the static disintegration process of chewable tablets； the rheometer was adopted to measure the viscoelasticity， thixotropy， and deformability of chewable tablets during the chewing process.RESULTSThe disintegration time limit， principal component content， and dissolution of self-made Glucosamine hydrochloride chewable tablets all met the limit requirements. The in vitro simulation results of the texture analyzer showed that self-made chewable tablets were easy to chew in both axial and radial directions， and the force required for chewing was within the range of the chewing force of the teeth； chewable tablets could disintegrate at an appropriate time without being chewed and only taken in the oral cavity. The in vitro simulation results of the rheometer showed that the chewable tablets in the oral cavity exhibited a behavior of elasticity as the main factor and viscosity as the secondary factor through the continuous stirring of the tongue， and the viscosity of the chewable tablets gradually decreased with tongue stirring or tooth chewing； when chewing with teeth， the internal force of the chewing tablets decreased， causing plastic deformation and crushing. After being crushed， the shape couldn’t be restored， making it easy to chew and swallow.CONCLUSIONSThe combination of texture analyzer and rheometer can be used to simulate the oral chewing process and evaluate the palatability and chewability of self-made Glucosamine hydrochloride chewable tablets. This model can provide reference for the evaluation of various chewable tablets.关键词：texture analyzer;rheometer;in vitro simulation;oral chewing;quality evaluation

Model rats were randomly divided into model group， low dose leonurine group （8 mg/kg）， high dose leonurine group （16 mg/kg）， HMGB1 overexpression group （8 μg/kg）， and high dose leonurine+HMGB1 overexpression group （16 mg/kg+8 μg/kg）， with 14 rats in each group. Another 14 rats were selected as the sham operation group. Rats in each group were injected with corresponding drugs or normal saline via abdominal cavity or tail vein once a day for 5 consecutive days. After the last administration， the levels of serum amylase （AMS） and lipase （LPS） were detected； the pathological injury of pancreatic tissue was observed； the levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， malondialdehyde （MDA） and superoxide dismutase （SOD）， mRNA and protein expressions of HMGB1 and RAGE in pancreatic tissues were detected.RESULTSCompared with model group， the structure of pancreatic tissue in rats gradually recovered in low and high dose leonurine groups； inflammatory cell infiltration gradually decreased； the pathological injury score and the levels of AMS， LPS， TNF-α， IL-6， MDA， the mRNA and protein expressions of HMGB1 and RAGE were significantly decreased， while the SOD levels were significantly increased （P＜0.05）. The high dose leonurine group showed more significant improvement （P＜0.05）； the pathological damage of pancreatic tissue in the HMGB1 overexpression group worsened， and except for a decrease in SOD levels， all other quantitative indicators increased significantly （P＜0.05）. Overexpression of HMGB1 could reduce the improvement effect of high dose leonurine on the above indexes in SAP rats （P＜0.05）.CONCLUSIONSLeonurine may alleviate pancreatic injury， inflammation and oxidative stress in pancreatic tissue of rats with SAP by inhibiting the HMGB1/RAGE signaling pathway.关键词：severe acute pancreatitis;HMGB1;RAGE;pancreatic injury

They were divided into control group （196 cases） and observation group （155 cases） according to different treatment regimens. The control group received conventional standard treatment， and the observation group was additionally given Liraglutide injection 0.6 mg/d subcutaneously once a day based on the control group， adjusted to 1.2 mg/d after 7 days. Both groups received regular treatment for more than 12 months. The propensity matching method was used to match the two groups of patients at a ratio of 1∶1. The cardiovascular metabolism indexes and cardiac ultrasound parameters were compared， and the correlation between left ventricular structure， function parameters and cardiovascular metabolism indexes was analyzed.RESULTSAfter propensity score matching， there was no significant difference in baseline clinical data between the two groups （each 155 cases） before treatment （P＞0.05）. After 12 months of treatment， the waist circumference， weight， body mass index （BMI）， systolic blood pressure （SBP）， fasting blood glucose （FBG）， glycosylated hemoglobin （HbA1c） and triglyceride （TG） of both groups， as well as the diastolic blood pressure （DBP）， total cholesterol （TC）， uric acid （UA） and left ventricular mass （LVM） of the observation group， exhibited a significant decrease compared to pre-treatment levels （P＜0.05）. The high-density lipoprotein cholesterol （HDL-C）， estimated glomerular filtration rate （eGFR）， and E/A ratio in both groups， as well as the aspartate aminotransferase （AST） in the control group and the left ventricular ejection fraction （LVEF） in the observation group， were all significantly increased compared with before treatment in the same group （P＜0.05）. Moreover， the improvement of the above indicators （except for TG and SBP） in the observation group was generally more significant than those in the control group （P＜0.05）. The left ventricular structure and functional parameters （LVM， LVEF， E/A ratio） of the two groups before and after treatment had varying degrees of correlation with the patients’ waist circumference， body weight， BMI， SBP， FBG and HbA1c. Moreover， BMI （observation group： β＝0.229， P＝0.004） and SBP （control group： β＝0.240， P＝0.004； observation group： β＝0.226， P＝0.007） were independent influential factors for LVM of the patients.CONCLUSIONSLiraglutide combined with conventional standard treatment can effectively control blood glucose in NAFLD patients with T2DM， reduce waist circumference， body weight and blood pressure， improve blood lipid disorders， and protect their cardiac structure and function.关键词：type 2 diabetes mellitus;liraglutide;cardiovascular risk

The blood trough concentration/daily dose （c0/D） values of the four groups were analyzed on the 14th day， 1 month and 3 months after renal transplantation. The incidence of acute rejection and the incidence of tacrolimus-related adverse reactions within 3 months after transplantation were compared among 4 groups.RESULTSOn the 14th day， 1 month and 3 months after surgery （except for the CYP3A5*1+WZ group）， c0/D values of CYP3A5*1 genotype patients were significantly lower than those of CYP3A5*3/*3 genotype patients regardless of whether they were treated with WZ additionally （P＜0.05）. Within 3 months after surgery， although there was no significant difference in the incidence of acute rejection and tacrolimus-related adverse reactions among the four groups （P＞0.05）， the incidence of hyperglycemia in patients with CYP3A5*3/*3 was higher （41.67%）.CONCLUSIONSCYP3A5 gene polymorphism is significantly related to tacrolimus c0/D in kidney transplant patients. Under the premise of c0 monitoring of tacrolimus， patients with CYP3A5*1 genotype should be given WZ as soon as possible after surgery to accelerate tacrolimus to reach the therapeutic concentration range， while CYP3A5*3/*3 genotype is not recommended to be given WZ because of the higher risk of hyperglycemia.关键词：gene polymorphism;Wuzhi capsule;tacrolimus;renal transplantation;adverse reactions

发布时间：2024-07-25 - 摘要：OBJECTIVETo investigate the effects of sacubitril/valsartan on renal function in patients with primary hypertension.METHODSA retrospective study was conducted among patients with primary hypertension who were admitted to PLA Strategic Support Force Characteristic Medical Center from January 2018 to June 2023. Based on their medication， they were divided into two groups： sacubitril/valsartan group and valsartan group. Propensity score matching was used to match baseline data between the two groups. Patients were treated with antihypertensive drugs based on improving their lifestyle. Sacubitril/valsartan group additionally received oral administration of 200 mg Sacubitril/valsartan tablets once daily， while valsartan group additionally received oral administration of 80 mg Valsartan capsules once daily. The increase amplitude of serum creatinine from baseline， the proportion of patients with elevated serum creatinine ＞30%-50% or ＞50%， and the proportion of patients with hyperkalemia （serum potassium ≥5.5 mmol/L） were compared between two groups at 2 months and 6 months after treatment. The trends of changes in serum creatinine， serum potassium and estimated glomerular filtration rate （eGFR） were compared between the two groups before treatment （at baseline）， 2 months and 6 months after treatment.RESULTSAfter propensity score matching， there were 62 patients in sacubitril/valsartan group and 61 patients in valsartan group； there were no significant differences in baseline characteristics between the two groups before treatment （P＞0.05）， indicating comparability. After 6 months of treatment， the increase of serum creatinine in the sacubitril/valsartan group was significantly lower than that in the valsartan group （P＝0.003）； the proportion of patients with elevated serum creatinine ＞30%-50% in the sacubitril/valsartan group was significantly lower than that in the valsartan group （P＝0.045）. None of the patients experienced hyperkalemia events after 2 months and 6 months of treatment. Repeated measures analysis of variance showed significantly statistical differences in serum creatinine and eGFR between the two groups within 6 months of treatment （P＜0.001）. Patients taking valsartan experienced a continuous increase in serum creatinine levels and a decrease in eGFR， while patients taking sacubitril/valsartan showed a first increase and then a decrease in serum creatinine levels， and a first decrease and then an increase in eGFR with a prolonged duration of medication.CONCLUSIONSSacubitril/valsartan can delay or even reverse the decline in renal function levels， and limit the deterioration of renal function in patients with primary hypertension， without increasing the risk of hyperkalemia.关键词：primary hypertension;renal function;serum creatinine;serum potassium;eGFR

发布时间：2024-07-25 - 摘要：OBJECTIVETo evaluate the efficacy and safety of dimethyl fumarate （DMF） in the treatment of multiple sclerosis （MS）.METHODSRetrieved from CBM， Web of Science， PubMed， the Cochrane Library， Embase， CNKI， Wanfang Data， and VIP， randomized controlled trials （RCTs） about DMF （trial group） versus other drugs or placebo （control group） were collected. After data screening and extraction， quality evaluation， meta-analysis was conducted by using RevMan 5.3 software.RESULTSA total of 6 literature were included， involving 638 patients. Results of meta-analysis showed that the proportion of patients with lesion changes after treatment in the trial group was lower than control group [MD＝－0.65， 95%CI（－1.27， －0.02）， P＝0.04]； there was no statistical significance in recurrence rate [RR＝1.06， 95%CI（0.52，2.17）， P＝0.88]， the proportion of patients with new lesions after treatment [RR＝1.05， 95%CI（0.62，1.80）， P＝0.85]， expanded disability status scale after treatment [MD＝0.02，95%CI （－0.18， 0.23）， P＝0.82]， the incidence of adverse events [RR＝1.33， 95%CI（0.97， 1.84）， P＝0.08] or severe adverse events [RR＝0.95，95%CI（0.48，1.90），P＝0.89] between 2 groups. Results of sensitivity analysis showed the study obtained unstable recurrence rate and the incidence of adverse events， while other results were robust.CONCLUSIONSDMF can control the lesion progression in MS patients to some extent and doesn’t increase the incidence of adverse events and serious adverse events， but there is no significant advantage in reducing the recurrence rate and controlling the disability progression.关键词：multiple sclerosis;disease modification treatment;recurrence rate;adverse event

发布时间：2024-07-25 - 摘要：OBJECTIVETo compare the general status of training programs for geriatric clinical pharmacists in China and the United States， and provide a reference for further optimizing training programs of geriatric clinical pharmacists in China.METHODSRetrieved from the American Society of Health-System Pharmacists （ASHP） website and the Chinese Hospital Association website， the detailed information and data on training outline， institution type/scale， enrollment number， training contents， project application conditions and graduation assessments for clinical pharmacists in geriatric field were collected and statistical analysis was performed using Excel software. RESULTS &CONCLUSIONSAs of January 12， 2024， ASHP provided 24 geriatric clinical pharmacist training programs and 25 positions available for application in the postgraduate year two training， which provided compensation. The training base involved hospitals and pharmaceutical colleges， with varying scales. Applicants needed to obtain a doctor of pharmacy and complete postgraduate year one training. ASHP had designed detailed training objectives for the four essential skills of basic patient care， advanced patient care， leadership and management skills， and knowledge education and teaching dissemination. Each training base could appropriately add optional skills such as academic skills， long-term care skills and other skills according to its characteristics， developed a student rotation plan， and conducted assessments and evaluations at multiple time points during the training process. There were 5 training programs for geriatric clinical pharmacists in China， with 15 positions， which didn’t provide compensation； training bases were all third-grade class A hospitals with relatively large scale. The applicant needed to obtain a bachelor’s degree or above， and different years of work were required based on their major and degree level. The Pharmaceutical Specialized Committee of the China Hospital Association had established a detailed training outline， proposing specific training objectives on theoretical knowledge， practical skills， scientific research thinking， etc. The training base organized assessments and evaluations at the time of enrollment， completion of specified content training， and graduation. According to the experience of the US， it is recommended to provide differentiated knowledge and skills training for students at different levels， flexibly arrange rotating departments， require students to work independently and deeply participate in clinical teaching and research work， conduct multiple and various forms of assessments， and adjust learning plans in a timely manner to comprehensively enhance their abilities.关键词：clinical pharmacist;training program;post-graduate education

发布时间：2024-07-25 - 摘要：odium-glucose linked transporter 2 inhibitors（SGLT2i） are novel oral hypoglycaemic agents and are widely used for hypoglycemic therapy in patients with type 2 diabetes mellitus， but differences in the genetic backgrounds of patients often lead to variable responsiveness to drug therapy. By summarizing the pharmacogenomic studies of SGLT2i， the article found that the genetic variants of UGT1A9， UGT2B4， SLC5A2， ABCB1， PNPLA3 and WFS1 may influence the pharmacokinetics of SGLT2i and the external hypoglycemic effects of SGLT2i in improving non-alcoholic fatty liver disease， weight loss and so on， but there is no clinical evidence that genetic polymorphisms affect the hypoglycemic efficacy of SGLT2i.关键词：SGLT2i;individual differences;pharmacogenomics;pharmacokinetics;pharmacodynamics

发布时间：2024-07-25 - 摘要：Renal interstitial fibrosis（RIF） is the main pathological manifestation of chronic kidney disease. Due to the complexity of the mechanism， there is no specific treatment for RIF in clinical practice. The abnormal activation of the phosphatidylinositol 3-kinase （PI3K）/protein kinase B（Akt） signaling pathway and the activation of downstream target genes are key drivers of RIF induction and progression. Traditional Chinese medicine has the characteristics of precise efficacy and minimal toxic side effects， and the occurrence and development of RIF can be regulated by multiple targets and mutual coordination. This review focuses on the PI3K/Akt signaling pathway and summarizes the potential targets and regulatory mechanisms of traditional Chinese medicine in the treatment of RIF. It is found that various effective ingredients （such as sinomenine， mangiferin， coumarin derivates from Hydrangea paniculata， etc.） and formulas （such as Fushengong decoction， Qi-Bang-Yi-Shen formula， etc.） of traditional Chinese medicine can inhibit fibroblast proliferation， improve inflammation and oxidative stress， maintain mitochondrial stability， and slow down ferroptosis through this pathway， thereby delaying the occurrence and progression of RIF.关键词：PI3K/Akt signaling pathway;renal interstitial fibrosis;action of mechanism
