OBJECTIVE To summarize the current situation of pharmaceutical clinic service in our hospital over the past five years， and explore sustainable development strategies for service models of pharmaceutical clinics. METHODS A retrospective analysis was conducted on the consultation records of patients who registered and established files at the pharmaceutical clinic in our hospital from January 2019 to December 2023. Statistical analysis was performed on patients’ general information， medication- related problems， and types of pharmaceutical services provided by pharmacists. RESULTS A total of 963 consultation records were included， among which females aged 20-39 years accounted for the highest proportion （66.04%）； obstetrics and gynecology- related consultations accounted for the largest number of cases. Additionally， 80 patients attended follow-up visits at our hospital’s pharmaceutical clinic. A total of 1 029 medication-related issues were resolved， including 538 cases of drug consultations （52.28%）， 453 medication recommendations （44.02%）， 22 medication restructuring（2.14%）， and 16 medication education （1.55%）； the most common types of medication-related problems identified were adverse drug events（70.07%）. CONCLUSIONS Although the pharmaceutical clinic has achieved recognition from clinicians and patients， challenges such as low awareness among healthcare providers and the public persist. Future efforts should focus on strengthening information technology construction， enhancing pharmacist training， and establishing various forms of outpatient pharmaceutical service models.

OBJECTIVE To evaluate the effects of different functional dyspepsia(FD)modeling methods and explore the thera-peutic effect and potential mechanism of Banxia Xiexin Decoction on FD.METHODS BALB/c mice were randomly divided into the blank group,iodoacetamide group,loperamide group,tail clamp group and vinegar group.After 1 week of intervention,the status of mice in each group was observed and their gastrointestinal motility,hormone levels and pathological changes were detected.A more i-deal FD modeling method was evaluated and determined.After modeling,different doses of Banxia Xiexin Decoction were given to in-tervene,and the changes in the gastrointestinal function of mice were observed.The expression of related proteins was studied by im-munohistochemistry,ELISA,Western Blot and other experimental methods.RESULTS Comparing the four modeling methods,it was found that the mice in the iodoacetamide group,loperamide group,and vinegar group showed weight loss compared to the blank group;the gastric emptying rate and small intestinal propulsion rate of mice in the iodoacetamide group and vinegar group decreased;changes in gastrointestinal hormones were found in the serum of mice in the tail clip group and vinegar group.Finally,the iodoacetamide meth-od was evaluated as the optimal FD modeling method.The administration results showed that Banxia Xiexin Decoction had no signifi-cant effect on the food intake and body weight of FD mice,while medium and high doses could improve the physical condition of FD mice,increase their gastric emptying rate and small intestine propulsion rate.The experimental results of immunohistochemistry,West-ern blotting,and ELISA confirmed that medium and high doses of Banxia Xiexin Decoction can significantly reduce the expression lev-els of TNF-α and IL-6 in the duodenum and serum of FD mice.CONCLUSION The iodoacetamide method is a better FD modeling method.Banxia Xiexin Decoction can improve the condition of FD mice,increase gastrointestinal motility,reduce the secretion of in-flammatory factor,thereby achieving the therapeutic effect of treating FD.

Objective:To investigate the therapeutic efficacy and underlying mechanisms of the traditional Chinese medicine formula "Hua Xian Fang" (HXF) in the treatment of radiation-induced pulmonary fibrosis (RIPF).Methods:In vivo experiment, 36 male specific pathogen free (SPF)-grade C57BL/6 mice aged 6-8 weeks were randomly divided into the control, irradiation (17 Gy thoracic irradiation), and irradiation+HXF groups (17 Gy thoracic irradiation+HXF). After 16 weeks, lung coefficient, HE staining and Masson staining were used to evaluate the degree of pulmonary inflammation and fibrosis. Immunohistochemistry was performed to measure the expression levels of α-smooth muscle actin (α-SMA) in lung tissues. Quantitative real-time PCR (qPCR) was performed to detect the mRNA expression levels of interferon-γ (IFN-γ). Enzyme linked immunosorbent assay (ELISA) was conducted to determine the levels of IFN-γ in serum and bronchoalveolar lavage fluid (BALF). During in vitro experiment, NIH/3T3 fibroblasts were stimulated with IFN-γ after 6 Gy irradiation, followed by 48 hours of culture. qPCR, immunofluorescence staining, and Western blot were used to assess the expression of α-SMA and collagen Ⅰ at the transcription and protein levels. One way ANOVA was used for multiple group comparisons, and Tukey test was used for inter group multiple comparisons. Results:Compared to the control group, mice in the irradiation group showed significant increases in lung coefficient, Szapiel score, Ashcroft score, and α-SMA expression in lung tissues (all P<0.001). Compared to the irradiation group, the irradiation+HXF group exhibited significant decreases in the above indicators (all P<0.001). qPCR demonstrated that the mRNA expression levels of IFN-γ were significantly higher in the irradiation+HXF group than that in the irradiation group ( P=0.001). ELISA results showed that the levels of IFN-γ in serum and BALF were significantly elevated in the irradiation+HXF group compared to those in the irradiation group ( P=0.032, 0.037). In vitro experiment revealed that after irradiation, the expression levels of α-SMA and collagen Ⅰ mRNA and protein in NIH/3T3 cells were significantly increased, while decreased after IFN-γ stimulation. Conclusion:HXF effectively alleviates RIPF, probably by the upregulation of IFN-γ in blood and tissues and inhibition of fibroblast activation.

OBJECTIVE: To observe the levels of soluble programmed cell death protein 1 (sPD-1) and soluble programmed cell death ligand 1 (sPD-L1) in peripheral blood of lymphoma patients, and reveal their clinical significances. METHODS: The peripheral blood specimens and clinical data of 64 newly diagnosed lymphoma patients and 30 healthy volunteers were collected. The levels of sPD-1 and sPD-L1 were detected by enzyme-linked immunosorbent assay (ELISA), and their correlations with clinical characteristics of the patients including pathological type, stage, lactate dehydrogenase (LDH) level, T cell subsets were analyzed. RESULTS: The levels of both sPD-1 and sPD-L1 in peripheral blood of lymphoma patients were higher than those of normal controls (P <0.05). There were no significant differences in sPD-1 and sPD-L1 levels in peripheral blood between Hodgkin lymphoma and non-Hodgkin lymphoma patients. Different pathological subtypes of lymphoma had different levels of sPD-1. The level of sPD-1 in patients with T-cell lymphoma was higher than that in patients with B-cell lymphoma (P =0.001). The levels of both sPD-1 and sPD-L1 in patients with Ann Arbor stage III and IV were higher than those in patients with stage I and II (P <0.05). The level of sPD-L1 in patients with abnormally increased LDH was higher than that in patients with normal LDH (P =0.001), but there was no significant difference in sPD-1 level. T cell subset analysis showed that the level of sPD-L1 was negatively correlated to CD4⁺ T cell content (r =-0.265). CONCLUSION The levels of sPD-1 and sPD-L1 in peripheral blood of lymphoma patients are related to the pathological type, Ann Arbor stage, LDH content and T cell subsets, and will be potential biomarkers in predicting the prognosis of lymphoma.

The blood-brain barrier(BBB), a protective barrier between brain tissues and brain capillaries, can prevent drugs from entering the brain tissues to exert the effect, which greatly increases the difficulty in treating brain diseases. The drug delivery system across the BBB can allow efficient drug delivery across the BBB by virtue of carriers and formulations, thereby enhancing the therapeutic effect of drugs on brain tissue diseases. Liposomes and micelles have been extensively studied with advances in the targeted therapy across the BBB for the brain due to their unique structures and drug delivery advantages. This study summarized the research status of liposome and micelle drug delivery systems across the BBB based on the literature in recent years and analyzed their application advantages and mechanism in terms of trans-BBB capability, targeting, and safety. Moreover, the problems and possible countermeasures in the research on trans-BBB liposomes and micelles were discussed according to the current clinical translation, which may provide refe-rences and ideas for the development of trans-BBB targeted nano-drugs.

Objective: To understand the characteristics and associated factors of viral nucleic acid conversion in children infected with Omicron variant strain of SARS-CoV-2 in Shanghai. Methods: The clinical symptoms, laboratory results and other data of 177 children infected with SARS-CoV-2 who were hospitalized in Shanghai Children's Hospital, School of Medicine, Shanghai Jiao Tong University (designated hospital for SARS-CoV-2 infection in Shanghai) from April 25 to June 8, 2022 were retrospectively analyzed. According to the chest imaging findings, the children were divided into mild and common type groups. According to their age, the unvaccinated children were divided into<3 years old group and 3-<18 years old group. According to the vaccination status, the children aged 3-<18 year were divided into non-vaccination group, 1-dose vaccination group and 2-dose vaccination group. Comparison between groups was performed by independent sample t-test and analysis of variance, and multivariate linear regression analysis was used for multivariate analysis. Results: Among the 177 children infected with Omicron variant of SARS-CoV-2, 96 were males and 81 were females, aged 3 (1, 6) years. The time of viral nucleic acid negative conversion was (10.3±3.1) days. The 177 children were 138 cases of mild type and 39 cases of common type. Among the children aged 3-<18 years old, 55 cases were not vaccinated, 5 cases received 1-dose and 36 cases received 2-dose vaccination. Among the 36 children who received 2 doses of vaccination, the time of viral nucleic acid negative conversion was shorter in those vaccinated within 6 months than those over 6 months ((7.1±1.9) vs. (10.8±3.0) d, t=-3.23, P=0.004). Univariate analysis showed that the time of nucleic acid negative conversion of SARS-CoV-2 was associated with age, underlying diseases, gastrointestinal symptoms, white blood cell count, proportion of neutrophils, proportion of lymphocytes, and the number of doses of SARS-CoV-2 vaccine (t=3.87, 2.55, 2.04, 4.24, 3.51, 2.92, F=16.27, all P<0.05). Multiple linear regression analysis showed that older age (β=-0.33, 95% CI -0.485--0.182, P<0.001) and more doses of vaccination (β=-0.79, 95% CI -1.463--0.120, P=0.021) were associated with shortened nucleic acid negative conversion time in children, while lower lymphocyte proportion (β=-0.02, 95% CI -0.044--0.002, P=0.031) and underlying diseases (β=1.52, 95% CI 0.363-2.672, P=0.010) were associated with prolonged nucleic acid negative conversion time in children. Conclusion: The children infected with Omicron variant of SARS-CoV-2 with reduced lymphocyte proportion and underlying diseases may have longer time of viral nucleic acid negative conversion,while children with older age and more doses of vaccination may have shorter time of viral nucleic acid negative conversion.

Background/Aims: To determine the value of salivary pepsin in discriminating sub-types of gastroesophageal reflux disease (GERD) and GERD-related disorders. Methods: Overall, 322 patients with different sub-types of GERD and 45 healthy controls (HC) were studied. All patients took Gastroesophageal Reflux Disease Questionnaire (GerdQ) and underwent endoscopy and 24-hour esophageal pH monitoring and manometry. Salivary pepsin concentration (SPC) was detected by using colloidal gold double-antibody immunological sandwich assay. Oral esomeprazole treatment was administrated in the patients with non-erosive reflux disease (NERD) and extra-esophageal symptoms (EES). Results: Compared to HC, patients with erosive esophagitis, NERD, EES, EES plus typical GERD symptoms, or Barrett’s esophagus had a higher prevalence of saliva and SPC (all P < 0.001). There was no significant difference in the positive rate for pepsin in patients with functional heartburn or GERD with anxiety and depression, compared to HC. After esomeprazole treatment, the positive rate and SPC were significantly reduced in NERD (both P < 0.001) and in EES (P = 0.001 and P = 0.002, respectively). Of the 64 NERD patients, 71.9% (n = 46) were positive for salivary pepsin, which was significantly higher than the rate (43.8%, n = 28) of pathological acid reflux as detected by 24-hour esophageal pH monitoring (P = 0.002). Conclusions Salivary pepsin has an important significance for the diagnosis of GERD and GERD-related disorders. Salivary pepsin and 24-hour esophageal pH monitoring may complement with each other to improve the diagnostic efficiency.

Objective To study the aging-related lifestyle and behaviors associated with the middle-aged and elderly so as to propose anti-aging strategies. Methods The aging degree of the elderly was measured by PPSHAS scale, which was certified by the national society. At the same time, the anti-aging factors were studied by questionnaire and logistic model. Results There were 836 effective PPSHAS scales and anti-aging questionnaires, 471 of which were significantly younger or older. Mann-Whitney U test showed that there was no significant difference in satiety and smoking between the two groups (Psatiety=0.295, Psmoking=0.294). By incorporating meaningful factors into logistic model, seven related anti-aging factors, such as dressing, drinking frequency and tea drinking habits, were obtained. Conclusions Aging can be delayed by paying attention to dressing, limiting alcohol, getting enough sleep, strengthening exercise, maintaining a harmonious family atmosphere, and drinking tea regularly.
