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.

OBJECTIVES: Calcium silicate (CSO) is modified to give it photothermal antibacterial properties. Its application potential in tooth mineralization and oral antibacterial is evaluated. METHODS: Based on defect-engineering modification strategy, a series of CSO-T samples (CSO-300, CSO-400, CSO-500, CSO-600) was obtained by introducing oxygen vacancy into CSO through thermal reduction using sodium borohydride. The samples were tested using scanning electron microscopy (SEM), X-ray diffraction, X-ray photoelectron spectroscopy, ultraviolet near-infrared absorption spectroscopy, and infrared thermography. The powder samples with the best photothermal performance and the most suitable material concentration (CSO-500, 500 μg/mL) were selected for subsequent experiments. High resolution transmission electron microscopy was used to analyze the microstructure and morphology of the sample, and MTT assay and Calcein AM/PI live/dead cell staining were used to evaluate the toxicity and compatibility of the sample to human oral keratinocytes. Escherichia coli and Staphylococcus aureus were selected for photothermal antibacterial experiments to evaluate their in vitro antibacterial performance. SEM, energy dispersive spectrometer, and micro Vickers hardness tester were used to evaluate the ability of materials to induce in vitro remineralization of detached teeth. RESULTS: Oxygen vacancies changed the crystal type and lattice spacing of CaSiO₃, broadened the light-absorption range, and gave it a good photothermal conversion ability in response to near infrared. Invitro experiments showed that the modified CaSiO₃ could promote the formation of hydroxyapatite on the tooth surface, thereby promoting the remineralization of teeth and improving the teeth hardness. Moreover, it had photothermal antibacterial properties and no cytotoxicity. CONCLUSIONS Defect-modified black calcium silicate has multiple functions, such as promoting tooth remineralization and photothermal bacteriostatic. When combined with the infrared luminescent toothbrush, it can simply and effectively treat tooth enamel erosion and oral bacteriostatic diseases caused by the excessive consumption of carbonated beverages and other daily bad living habits. This combination is expected to achieve the synergic treatment effect of tooth remineralization and oral bacteriostatic through daily cleaning is expected.

Background Bacteria are the most diverse and widely sourced microorganisms in the indoor air of subway stations, where pathogenic bacteria can spread through the air, leading to increased health risks. Objective To understand the status and distribution characteristics of indoor air bacterial pollution in subway stations and compartments in a city of Central South China, and to provide a scientific basis for formulating intervention measures to address indoor air bacteria pollution in subways. Methods Three subway stations and the compartments of trains parking there in a city in Central South China were selected according to passenger flow for synchronous air sampling and monitoring. Temperature, humidity, wind speed, carbon dioxide (CO₂), fine particulate matter (PM_2.5), and inhalable particulate matter (PM₁₀) were measured by direct reading method. In accordance with the requirements of Examination methods for public places-Part 3: Airborne microorganisms (GB/T 18204.3-2013), air samples were collected at a flow rate of 28.3 L·min⁻¹, and total bacterial count was estimated. Bacterial microbial species were identified with a mass spectrometer and pathogenic bacteria were distinguished from non-pathogenic bacteria according to the Catalogue of pathogenic microorganisms transmitted to human beings issued by National Health Commission. Kruskal-Wallis H test was used to compare the subway hygiene indicators in different regions and time periods, and Bonferroni test was used for pairwise comparison. Spearman correlation test was used to evaluate the correlation between CO₂ concentration and total bacterial count. Results The pass rates were 100.0% for airborne total bacteria count, PM_2.5, and PM₁₀ in the subway stations and train compartments, 94.4% for temperature and wind speed, 98.6% for CO₂, but 0% for humidity. The overall median (P₂₅, P₇₅) total bacteria count was 177 (138,262) CFU·m⁻³. Specifically, the total bacteria count was higher in station halls than in platforms, and higher during morning peak hours than during evening peak hours (P<0.05). A total of 874 strains and 82 species were identified by automatic microbial mass spectrometry. The results of identification were all over 9 points, and the predominant bacteria in the air were Micrococcus luteus (52.2%) and Staphylococcus hominis (9.8%). Three pathogens, Acinetobacter baumannii (0.3%), Corynebacterium striatum (0.1%), and Staphylococcus epidermidis bacilli (2.2%) were detected in 23 samples (2.6%), and the associated locations were mainly distributed in train compartments during evening rush hours. Conclusion The total bacteria count in indoor air varies by monitoring sites of subway stations and time periods, and there is a risk of opportunistic bacterial infection. Attention should be paid to cleaning and disinfection during peak passenger flow hours in all areas.

Objective:To evaluate the efficacy and safety of vedolizumab (VDZ) monoclonal antibody in maintenance therapy for ulcerative colitis (UC) .Methods:A retrospective case control study was conducted, including 84 patients with active UC undergoing VDZ therapy for an average of (22±8) weeks in the Department of Gastroenterology, the Second Affiliated Hospital of Zhejiang University School of Medicine from December 2020 to September 2023. These patients achieved a response or remission by (22±8) weeks and continued follow-up until (54±8) weeks. They were divided into effective and ineffective groups based on whether they achieved clinical remission by (54±8) weeks after using VDZ; those who required optimized treatment with shortened injection intervals were included in the ineffective group. Baseline clinical data, medication history and endoscopic imaging data were recorded. The clinically modified Mayo score, Mayo endoscopic score, and other assessments were used to evaluate UC disease activity. Adverse reactions related to treatment were also recorded to assess the efficacy of VDZ treatment up to (54±8) weeks was assessed and key factors affecting clinical remission of the disease were analyzed.Results:Among the 84 UC patients with followed up to (54±8) weeks, 47 cases (55.95%) achieved clinical remission and were classified as the effective group, while 37 cases (44.05%) did not achieve clinical remission and were classified as the ineffective group. The endoscopic remission rate in the effective group was 68.09% (32/47), and the mucosal healing rate was 36.17% (17/47). Joint pain occurred in 2.38% of patients, hepatic dysfunction in 3.57%, and one patient died from leukemia following a COVID-19 infection during the maintenance therapy period.Conclusion:VDZ has a certain efficacy in the continuous treatment of UC patients and in maintaining clinical and endoscopic remission, with generally high overall safety and a low incidence of adverse reactions.

Objective:To evaluate the role of nuclear factor erythroid 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway in the improvement in postoperative cognitive function by electroacupuncture preconditioning in aged rats.Methods:Eighty clean-grade healthy male Sprague-Dawley rats, aged 24 months, weighing 550-600 g, were divided into 4 groups ( n=20 each) using a random number table method: control group (C group), POCD group, electroacupuncture+ POCD group (EA group), and Nrf2 inhibitor ML385+ electroacupuncture+ POCD group (I group). A rat POCD model was prepared by performing exploratory laparotomy under 3% sevoflurane anesthesia. Nrf2 inhibitor ML385 15 mg/kg was intraperitoneally injected at 30 min before surgery in group I, while the equal volume of normal saline was given instead in the remaining groups. Electroacupuncture stimulation of the Zusanli, Hegu and Neiguan acupoints (disperse-dense waves, current intensity 1 mA, frequency 2/15 Hz, 30 min) was performed at 8: 00 a.m. every day for 5 days prior to model preparation in EA group and I group. An open field test was conducted at 3 days after operation to measure the autonomous motor function, and Morris water maze test was conducted after the end of the open field test at 3-7 days after operation to evaluate the cognitive function. After the Morris water maze test, the rats were sacrificed under anesthesia and hippocampal tissues were taken for determination of the level of reactive oxygen species (ROS, by flow cytometry) and expression of Nrf2 and HO-1 (by Western blot) and for examination of the mitochondrial ultrastructure of hippocampal neurons (with a transmission electron microscope). Results:Compared with group C, the escape latency was significantly prolonged, the number of crossing the original platform quadrant was decreased, the hippocampal ROS levels were increased, the expression of Nrf2 and HO-1 was down-regulated ( P<0.05), and mitochondria were swollen and mitochondrial cristae were broken in the hippocampal CA1 neurons in group POCD. Compared with group POCD, the escape latency was significantly shortened, the number of crossing the original platform quadrant was increased, the hippocampal ROS levels were decreased, the expression of Nrf2 and HO-1 was up-regulated ( P<0.05), and the swelling of mitochondria and rupture of cristae structure were improved in the hippocampal CA1 neurons in group EA. Compared with group EA, the escape latency was significantly prolonged, the number of crossing the original platform quadrant was decreased, the hippocampal ROS levels were increased, the expression of Nrf2 and HO-1 was down-regulated ( P<0.05), and the swelling of mitochondria and rupture of cristae structure were aggravated in the hippocampal CA1 neurons in group I. Conclusions:Activation of the hippocampal Nrf2/HO-1 signaling pathway is involved in improvement in postoperative cognitive function by electroacupuncture preconditioning in aged rats.

OBJECTIVE To systematically evaluate the adverse effects of drug-resistant tuberculosis （DR-TB） drugs on pregnant women and fetuses ，so as to provide evidence-based reference for clinical medication. METHODS PubMed，Cochrane Library，Embase，CBM，CNKI，Wanfang database and VIP were searched by computer to collect randomized controlled trials （RCTs），cohort studies ，case-control studies ，case series and case reports about pregnant women exposed to DR-TB drugs. The retrieval time limit was from the establishment of each database to August 20，2021. After selecting the literature and extracting the data，the bias risk assessment tool recommended by 6.2 version of Cochrane system evaluator manual was used to evaluate the quality of the included RCTs ；Newcastle-Ottawa scale was used to evaluate the quality of the included cohort studies and case-control studies ；IHE scale issued by the Canadian Institute of Health Economics （IHE）was used to evaluate the quality of the included case series and case reports. RevMan 5.1 software was used for Meta-analysis of non-comparative binary data. RESULTS A total of 13 literature were included ，including 7 case series and 6 case reports ，involving 203 patients and 204 newborns；among them，there were 6 literature about non-comparative binary data. The results of meta-analysis showed that after exposure to DR-TB drugs，no newborn had birth defects ；the mortality of pregnant women was 0.09[95％CI（0.06，0.15），P＜0.000 01]；the neonatal mortality was 0.02[95％CI（0，0.06），P＜0.000 01]；the incidence of preterm birth was 0.14[95％CI（0.03，0.43），P＝0.02]；the incidence of infants with low birth weight was 0.17[95％CI（0.04，0.51），P＝0.06]；the incidence of growth retardation was 0.15[95％CI（0.09，0.22），P＜0.000 01]；the incidence of stillbirth was 0.05[95％CI（0.02，0.09），P＜0.000 01]；the incidence of abortion was 0.08[95％CI（0.05，0.14），P＜0.000 01]. CONCLUSIONS Pregnant women exposed to DR-TB drugs can cause pregnant women ’s death and abortion ，neonatal death ，premature birth ，infants with low birth weight ，growth retardation and stillbirth，but there is no neonatal birth defect ；these adverse outcomes may be related to the history of DR-TB.
