OBJECTIVE To quantitatively and qualitatively analyze the progress of potentially inappropriate medication （PIM） research by means of bibliometrics， and to predict the hotspots and trends of PIM， so as to provide reference for PIM research in China. METHODS The research literature related to PIM were searched from Web of Science core database， and the publication trend of the literature was analyzed on the bibliometric online analysis platform and CiteSpace 5.8.R3 software. The research results were visualized and analyzed， and the research hotspots of PIM were summarized through gCLUTO. RESULTS About PIM research， the annual number of the literature issued from 2012 to 2021 showed a continuous growth trend totally； the United States had the largest number of literature （241 pieces）； the University of Sydney in Australia was the research institution with the largest number of literature （59 pieces）； O’Mahony D from University College Cork， Ireland， published the most literature （23 pieces）； the research of PIM involved 57 disciplines， among which there was the largest number of literature about gerontology （384 pieces）； International Journal of Clinical Pharmacy was the journal with the largest number of literature （61 pieces）； Journal of the American Geriatrics Society was cited most frequently （1 197 times）. The hotspots of PIM research mainly focused on seven aspects： the standard of PIM， the safety and economy research of PIM， the risk factors research of PIM， the PIM research of chronic patients， the PIM research of antipsychotics， the research of pharmacists’ participation in PIM management， and the PIM research about palliative care of tumor patients. CONCLUSIONS The heat of research on PIM has been on the rise， and there is little cooperation between countries and institutions， and more cooperation is needed. In the future， the focus of Chinese pharmacists’ research on PIM may be on the deep localization of PIM standards， PIM intervention and precise medication guidance， and PIM management of specific diseases and drugs.

OBJECTIVE To investigate the clinical efficacy and safety of rituximab （RTX） followed by belimumab （BLM） in patients with severe systemic lupus erythematosus（SSLE）. METHODS Nine SSLE patients， who were treated with RTX followed by BLM for more than 6 months in the Department of Rheumatology and Immunology of the First Affiliated Hospital of Zhengzhou University from October 2020 to June 2021， were enrolled. Baseline clinical data of patients， laboratory examination results and basic treatment status at weeks 0， 4， 12， and 24 of medication were collected retrospectively. The patients’ systemic lupus erythematosus disease activity index （SLEDAI） score， glucocorticoid dosage and serological indicators （complement C3， complement C4， serum albumin， and 24-hour urine protein quantification） level were analyzed. At the same time， the occurrence of adverse drug reaction was collected. RESULTS All 9 patients completed more than 24 weeks of RTX followed by BLM therapy. All patients suffered from renal impairment， of which 7 （77.8%） had renal pathology support， 3（33.3%） had blood system damage and 2 （22.2%） had nervous system damage. During treatment， with the prolongation of treatment time， the SLEDAI score， 24- hour urinary protein quantification， and glucocorticoid dosage of patients showed a significant downward trend， and ultimately decreased to the normal index level （P＜0.05）； serum albumin， complement C3 and complement C4 all showed a significant upward trend， eventually rose to the normal index level （P＜0.05）. During treatment and follow-up， 1 patient developed herpes zoster， 1 patient developed upper respiratory tract virus infection， and 1 patient developed urinary system bacterial infection. All patients recovered after symptomatic treatment. CONCLUSIONS In sequential use of RTX followed by BLM for SSLE， early administration of RTX can quickly stabilizethe condition， significantly alleviate clinical symptoms， and gradually normalize specific serological indicators； subsequent administration of BLM can reduce the type and dosage of basic treatment drugs； there is no increase in the incidence of adverse drug reactions.

OBJECTIVE To analyze the research status， hotspot and development trend of tyrosine kinase inhibitors （TKIs） in the treatment of human epidermal growth factor receptor 2 （HER2） positive breast cancer. METHODS The literature related to TKIs in the treatment of HER2 positive breast cancer were searched from the Web of Science core collection database； the author， country/region， institution， subject field， journal and keywords was visualized by CiteSpace 6.1.R3 software. RESULTS A total of 732 pieces of literature were included， and the number of literature published showed an increasing trend year by year. The number of literature published in the United States was the largest （center degree 0.10）， and the number of literature published in China ranked second （center degree 0.05）. The most published and cited authors were Crown from St. Vincent’s University Hospital in Australia and Slamon from University of California， Los Angeles in the United States； the institution with the highest number of literature was the University of Texas MD Anderson Cancer Center， and the journal with the highest number of literature was the Journal of Clinical Oncology. The research mainly focused on five aspects： HER2 positive breast cancer treatment drugs， TKIs receptor， TKIs mechanism of action， HER2 positive breast cancer brain metastasis， and TKIs clinical trials. The main frontier areas and development trends were the combination of TKIs with other drugs or therapies to enhance targeting and reduce toxic side effects. CONCLUSIONS The study of TKIs in the treatment of HER2 positive breast cancer has attracted the attention of scholars at home and abroad. Chinese scholars and research teams need to strengthen cooperation and communication in the future， and cooperation with other countries should be strengthened in terms of the efficacy and safety of TKIs alone and combined with other drugs in the treatment of HER2 positive breast cancer.

OBJECTIVE To investigate the working pressure of return-working postpartum hospital pharmacists， analyze the influential factors， and find the suitable strategy to relieve the working pressure of postpartum pharmacists. METHODS By the means of general information questionnaire， working pressure questionnaire and self-rating depression scale， the data of postpartum pharmacists were surveyed with sampling survey to investigate the working-pressure situation. The main influential factors of the postpartum working pressure were analyzed by multiple linear stepwise regression analysis. RESULTS A total of 281 valid questionnaires were collected from 84 different hospitals， with effective rate of 88.64%. The total score of working pressure for 281 postpartum pharmacists who were back to position was （79.80±23.06） （total score of 155）. However， 51.60% of return-working postpartum pharmacists showed depressive state （≥53）. The depression status was positively correlated with working pressure. Family support， frequency of physical exercise， and ideal personnel care were all negatively associated with working pressure. CONCLUSIONS The working pressure of return-working postpartum pharmacists is at a moderate level. Depression， family support， ideal personnel care， and frequency of physical exercise are the main influential factors.

Objective:To investigate the correlations of β cell dedifferentiation in non-diabetic subjects with risk factors for type 2 diabetes mellitus(T2DM).Methods:Immunofluorescence staining with insulin and β cell dedifferentiated marker ALDH1A3 was used to evaluate the β cell dedifferentiation levels in 38 non-diabetic and 23 T2DM. Correlation analyses were performed between β cell dedifferentiation levels and available clinical parameters including age, body mass index, HbA 1C level, triglycerides, and cholesterol levels in non-diabetic subjects. Results:β cell dedifferentiation level defined by the positive expression of ALDH1A3 in β cells(ALDH1A3 + INS + cell proportion) was significantly elevated in T2DM subjects( P<0.001). In PreD subjects, ALDH1A3 + INS + cells proportion were decreased( P=0.050) and negatively correlated with HbA 1C( r=-0.44, P=0.006), but not with age and body mass index. The analysis of correlation with lipidemic parameters showed that ALDH1A3 + INS + cells proportion was positively correlated with plasma total cholesterol level( r=0.39, P=0.045), but not plasma total triglyceride. Conclusion:ALDH1A3 + INS + cells were found to be decreased in prediabetes, suggesting that there may be enhanced β-cell identity in prediabetes to compensate for insulin secretion requirements; ALDH1A3 + INS + cells were elevated in people with high plasma total cholesterol levels, suggesting that total cholesterol may be one of the factors that induce β-cell dedifferentiation.

Objective:To evaluate the laparoscopic sleeve gastrectomy combined with hiatal hernia repair surgery for weight loss and antireflux.Methods:This study included 21 obese patients with gastroesophageal reflux who underwent laparoscopic sleeve gastrectomy at the Weight Loss Metabolism Center of the Department of Hepatobiliary and Pancreatic Surgery of Zhejiang Provincial People's Hospital from Dec 2019 to Dec 2020. Patients were divided into simple bariatric surgery group (9 cases) and simultaneous combined surgery group (12 cases).Results:In the combined surgery group, 1 case had postoperative gastric leakage. The postoperative body weight, waist circumference, and BMI indexes of the two groups showed a downward trend ( F=5.154, P=0.013; F=14.319, P<0.001; F=6.725, P=0.004). There was a statistically significant difference in the excess weight loss in both the two groups at 6 months after the operation compared to 1 month after the operation ( t=8.927, P<0.001; t=8.926, P<0.001). There was no statistically significant difference in postoperative lower esophageal sphincter resting pressure and Gerd symptom score in the bariatric surgery group compared with preoperative ( t=-0.891, P=0.507; t=0.629, P=0.298). The postoperative Gerd symptom score of the patients in the combined surgery group was significantly lower than that before the operation, and the resting pressure of the lower esophageal sphincter was significantly higher than that before the operation, ( t=-10.539, P<0.001; t=5.066, P=0.038). Conclusion:Combined surgery have the same weight loss effect as in simple bariatric surgery in obese patients with gastroesophageal reflux, in addition to stronger anti-reflux effect.

OBJECTIVE：To study the pr otective effect of schisandrin A （SA）on CCl 4-induced liver fibrosis model mice and its mechanism. METHODS ：Mice were randomly divided into blank control group ，model group ，silymarin group （positive control，100 mg/kg），SA low-dose and high-dose groups （20，40 mg/kg），with 10 mice in each group. Except for blank control group，other groups were given CCl 4 subcutaneously to induce liver fibrosis model. After successful modeling ，administration groups were given relevant medicine intragastrically ，once a day ，for consecutive 6 weeks；blank control group and model group were given constant volume of 0.5％sodium carboxymethyl cellulose solution intragastrically by the same way. HE staining was used to observe the pathological changes of liver tissue in mice. UV spectrophotometry and ELISA assay were adopted to detect the serum levels of liver injury indexes （ALT and AST ）and the contents of inflammatory factors （TNF-α，IL-1β，IL-6）. Western blotting assay was used to detect the expression of NOD like receptor protein 3（NLRP3）/NF-κB and TGF-β/Smad signaling pathway protein. RESULTS ：Compared with blank control group ，obvious pathological changes of liver fibrosis were observed in model group. The serum levels of liver injury indexes and contents of inflammatory factors were significantly increased （P＜0.01）. The expression of NLRP 3，apoptosis associated spot-like protein ，Caspase-1 and IL- 1β，TGF-β1 and ratios ofp-NF-κB p65/NF-κB p65，p-IκBα/IκBα，p-Samd3/Smad3 were increased significantly （P＜0.01）. Compared with model group ，SA could significantly relieve hepatic fibrosis in mice ，reduce serum levels of liver injury indexes and contents of inflammatory factors ，as well as the expression of NLRP 3/NF-κB and TGF-β/Smad signaling pathway protein and phosphorylation level（P＜0.01）. CONCLUSIONS ： SA can effectively relieve liver injury and inflammation of CCl 4-induced hepatic fibrosis model mice ，which may be through the regulation of NLRP 3/NF-κB and TGF-β/Smad3 signaling pathways ，thus inhibiting the process of liver fibrosis.

Background and Objectives: Adipose tissue-derived mesenchymal stem cells (ASCs) are recognized as an advantaged source for the prevention and treatment of diverse diseases including type 2 diabetes mellitus (T2DM). However, alterations in characteristics of ASCs from the aforementioned T2DM patients are still obscure, which also hinder the rigorous and systematic illumination of progression and pathogenesis. Methods: and Results: In this study, we originally isolated peripancreatic adipose tissue-derived mesenchymal stem cells from both human type 2 diabetic and non-diabetic donors (T2DM-ASCs, ND-ASCs) with the parental consent, respectively. We noticed that T2DM-ASCs exhibited indistinguishable immunophenotype, cell vitality, chondrogenic differentiation and stemness as ND-ASCs. Simultaneously, there’s merely alterations in migration and immunoregulatory capacities in T2DM-ASCs. However, differing from ND-ASCs, T2DM-ASCs exhibited deficiency in adipogenic and osteogenic differentiation, and in particular, the delayed cell cycle and different cytokine expression spectrum. Conclusions The conservative alterations of T2DM-ASCs in multifaceted characteristics indicated the possibility of autologous application of ASCs for cell-based T2DM treatment in the future.
