Objective To understand the characteristics and temporal trends of stroke incidence in the household population of Shanghai's Qingpu District and to provide a basis for the development of comprehensive prevention and control strategies. Methods The stroke case database for Qingpu District from 2017-2022 was obtained from the Shanghai Stroke and Acute Myocardial Infarction Registry and Reporting Information System. The average age of onset, incidence rate, standardised incidence rate, and constitutive ratio were calculated. Independent samples t-tests were used for comparisons between groups, 2-tests and 2-trend tests for comparisons of rates, and the Joinpoint regression model for calculating the annual percentage change (APC) to analyse the temporal trend of rates. Results Between 2017 and 2022, the average age of stroke onset in the household population of Shanghai's Qingpu District was 73.69±11.60 years. The average annual incidence rate was 556.62/100 000, with an average annual standardised incidence rate of 333.76/100000. There was an increasing trend in the incidence and standardised incidence of stroke in males (APC=7.06%, t=3.44, P=0.03, APC=5.32%, t=3.04, P=0.04). The incidence of stroke increases with age, with cases mainly concentrated in those aged 65 years and above, accounting for 79.47%. Ischemic stroke dominates the stroke typology, accounting for 91.08% of cases, while the incidence of hemorrhagic stroke shows an increasing trend (APC=4.64%, t=4.59, P=0.01). Conclusion The occurrence of stroke in the general population of Shanghai’s Qingpu District is concerning. The study indicates that males, individuals aged 65 years and above, and ischaemic stroke are significant factors that require attention for stroke prevention and control.

OBJECTIVE To optimize the formulation for sustained-release particles of matrine(MAT) and paeonol(PAE) and to primarily evaluate their quality. METHODS The sustained-release particles were fabricated by the extrusion-spheronization method. Single factor analysis was conducted on the main sustained-release materials and their dosage, auxiliary sustained-release materials, and the total amount and proportion of mixed sustained-release materials, using the cumulative release rates of MAT and PAE in vitro as evaluation indicators. By combining central composition design-response surface methodology, the formulation of sustained-release materials was optimized, and the effects of the total amount and mass ratio of ethyl cellulose(EC) and chitosan(CS) on the cumulative release rate and release synchronization of MAT and PAE were investigated. The formulation characteristics, in vitro release, and preliminary stability tests of MAT-PAE-SRPs were evaluated, and the release process kinetic equation was fitted. RESULTS The optimized formulation contained 23.5% EC and 17.1% CS as sustained-release materials. The yield, repose angle, bulk density and friability of final particles were 97.23%, 38.1°, 0.74 g·mL−1 and 0.74%, respectively. The particles showed sustained release pattern in various media and released faster in acidic media with its release percentage >90% at 12 h. The release profile of MAT was fitted best with first order equation, and that of paeonol with Higuchi equation. The formation of SRPs improved the stability of both drugs. CONCLUSION The sustained-release effect of MAT-PAE-SRPs prepared by sustained-release materials EC and CS is significant, and the cumulative release rate and release synchronization of MAT and PAE are good, which can provide reference for the research of dual loaded sustained-release formulations.

Methods From January 2019 to December 2020, a sample of 3,180 women in XX region who had sexual intercourse experience were randomly selected, and their HPV genotypes were tested using flow-through hybridization, then the distribution characteristics and types of HPV infection in women of different ages were observed. Results Among of 3 180 patients, HPV infection was predominant in women aged 31-50 years , with 25.85% (822/3 180) aged 31-40 years and 22.08% (702/3,180) aged 41-50 years. HPV infection was the least prevalent in the ≤25 and >60 years age groups, with 428 cases and 289 cases respectively. HPV infection occurred in 1 310 out of 3 180 women , with a positive infection rate of 41.19% (1 310/3 180). HPV infection was most prevalent in the ≤25 years and ≥60 years age groups, accounting for 56.78% and 67.13% respectively. Single infection was the main infection type in all age groups, accounting for 76.03%. Twenty-one HPV genetic subtypes were detected in the subjects, out of a total of 1 918 strains of the virus. The main high-risk subtypes for single infection were HPV16, HPV52 and HPV58, accounting for 13.92%, 13.87% and 12.57% respectively, followed by HPV53 and HPV33, accounting for 7.61% and 5.58% respectively. The predominant low-risk subtypes for single infection were HPV11, HPV8 and HPV6, with accounting for 7.51%, 5.47% and 5.01% respectively. Conclusion HPV infection in women in Shiyan, Hubei region is predominantly in the ≤25 and ≥60 years age groups, and early clinical screening and preventive measures such as vaccination for high-risk HPV typing are of vital importance.

Objective To analyze the effect of immune function on the condition and prognosis of asthma in children with asthma. Methods A total of 148 children with asthma diagnosed in Qinghai women and children's Hospital from January 2018 to January 2021 were included in the analysis, the immune function of the children was determined, and the information of all children was followed up for 6 months after treatment; compared The condition and follow-up prognosis of children with immunocompromised and normal immune function were analyzed and discussed, and the correlation between the expression levels of immunoglobulins (IgG, IgA, IgM) and the condition and short-term recurrence prognosis (6 months) of children was analyzed and discussed, so as to guide Prevention and clinical work. Statistical analysis was done using SPSS19.0. Results The average age of 148 children with recurrent respiratory tract infection in the study was (8.94±3.65) years old, including 70 male children. The condition of the children was evaluated and classified into mild/severe cases: 148 children in this study included mild cases. There were 98 cases and 50 severe cases. There were more males and lower BMI levels in severe children (P<0.05) . The levels of IgG, IgA and IgM in children were all lower in severe children (P<0.05) . The follow-up found that the proportion of relapses in critically ill children was higher (P<0.05). Comparing the levels of IgG, IgA, and IgM in mild and severe children, the average levels of IgG, IgA, and IgM in severe children were lower than those in the mild group, and the difference was statistically significant (P<0.05); recurrence within 6 months of follow-up Prognostic evaluation showed that 19 of the 148 children had relapse, and the levels of IgG, IgA, and IgM in severe relapsed children were significantly lower than those without relapse (P<0.05). Analysis of the relevant factors potentially affecting the prognosis of recurrence showed that gender (female) (OR=1.726) , BMI level (weight loss) (OR=1.613) , IgG expression level factor (low expression) (OR=1.898) , IgA expression Level factor (low expression) (OR=3.509) , IgM expression level factor (low expression) (OR=3.217) and disease factor (severe) (OR=3.619) were potential risk factors, which would increase the risk of poor prognosis. Conclusion The asthma attack in children with immunocompromised immune function is relatively severe, and the short-term recurrence probability is higher, which deserves clinical attention and preventive intervention.

Abstract OBJECTIVE To conduct visual analysis of the annual differentiated performance data of clinical pharmacists by using R language to find out the shortcomings and promote the progress of clinical pharmacists and department development. METHODS The weight scores of clinical pharmacists’ performance assessment in 2021 were collected, and R language was used to draw rectangular tree diagram, violin case diagram and Sankey diagram for data visualization analysis. RESULTS The basic work of clinical pharmacy department accounted for the largest weight, followed by clinical affairs, pharmaceutical quality control affairs and pioneering affairs in the middle of the weight, while teaching, scientific research weight was insufficient. There were also great differences in the weight of clinical pharmacists. Among the 8 clinical pharmacists, 3 focused on basic, 3 on all-round development, 1 on clinical, and the work weight of 1 needed to be comprehensively improved. CONCLUSION R language visualization can be used to analyze the weight composition of clinical pharmacy department, which is convenient to formulate the direction of department rectification and promote the improvement of clinical pharmacists team level.

AIM: To investigate the potential toxic effects of paclitaxel(PTX)on the proliferation, apoptosis, cell cycle, morphology, and blood-retinal barrier(BRB)of human retinal pigment epithelial cells(ARPE-19).

METHODS: ARPE-19 cells were cultured in vitro and divided into two groups: Control group(Control)and drug plus group(PTX). ARPE-19 cells were treated with different concentrations of PTX(0.005, 0.05, 0.5, 5mg/L)for a certain period of time(12, 24, 36, 48, 72h), and CCK8 assay and flow cytometry were used to detect the effects of drug on proliferation and apoptosis of ARPE-19 cells at different concentrations and time points. The same time, the cell cycle was detected by flow cytometry. Morphological changes of cells were observed by immunofluorescence. Expressions of apoptosis-related proteins and barrier function-related proteins were detected by Western blot. The effect of the drug on the cell barrier was measured by measuring the transepithelial resistance of the cells.

RESULTS: PTX reduced the proliferation ability of ARPE-19 cells. After 36h of treatment with low concentration of 0.005mg/L paclitaxel, cell proliferation began to be affected. At the same time, PTX accelerated cell apoptosis was dependent on drug concentration and time. Flow cytometry showed that the cells were arrested in the G2-M phase. In addition, PTX causes significant morphological changes in cells, with normal cells fusiform or irregular. In the PTX group, the number of cells decreased and the cell shape tended to be round. PTX affected retinal barrier function, and the transepithelial resistance of cells was significantly decreased after treatment, and the expression of tight junction proteins ZO-1 and Occludin were significantly decreased compared with the control group(P<0.05). The expression levels of Cleaved-caspase-3 and Bax were significantly increased compared with the control group, while the expression levels of Bcl-2 were significantly decreased(P<0.05)and was dependent on drug concentration and time.

CONCLUSION: PTX can affect the proliferation and apoptosis of ARPE-19 cells, and it depends on time and concentration. In addition, PTX affected the cell cycle and morphology of ARPE-19 cell. At the same time PTX can destroy the barrier function of the retina,suggesting that anti-tumor drugs have a potential toxic effect on the retina.

Ocular cicatricial pemphigoid(OCP)is a special manifestation of mucosal pemphigoid(mucous membrane pemphigoid, MMP), and the pathogenesis is not clear at present. It can be caused by variety factors such as antigen-antibody reaction, inflammation cell infiltration, the action of various cytokines, elevated calcium ion levels and susceptibility genes. In the early period of diseases, conjunctival present chronic progressive fibrotic inflammation, later the corneal opacity and the neovascularization will eventually lose vision. Therefore, it is particularly important to carry out clinical standardized treatment for OCP patients in a timely manner. To use medicine to control the inflammation and delay the progression of the disease, for example, dapsone, intravenous immunoglobulin(IVIG), rituximab(RTX), tumor necrosis factor antagonists and adrenocorticoids. Surgical treatment can be considered appropriately when OCP patients are complicated by severe trichiasis, corneal disease and cataract.

Keratoconus(KC)is a progressive disease characterized by gradual corneal thinning and ectasia, resulting in irregular astigmatism, myopia, and mild to severe visual impairment. Although the pathogenesis of KC is still unclear, twin studies and family-based studies have identified that the occurrence of KC is closely related to genetic factors. First-degree relatives of KC patients including their parents, siblings and offspring are very important for the family aggregation analysis and polygenic analysis of diseases. This review summarized the current situation of clinical and genetic research about first-degree relatives of KC patients, hoping to deepen the understanding of clinical manifestations and genetic characteristics of first-degree relatives of KC, and to provide new ideas for exploring the role of genetic and environmental factors in the pathogenesis of KC.

AIM: To investigate the therapeutic effect of conbercept injection combined with Ahmed valve implantation and phacoemulsification in the treatment of neovascular glaucoma(NVG).

METHODS: Retrospective analysis. Totally 18 patients(18 eyes)with NVG complicated combined with cataract in our hospital from June 2018 to January 2020. All patients received intraocular injection of conbercept at 3-7d before surgery, Ahmed valve implantation and phacoemulsification were performed after meeting the surgical indications. Best corrected visual acuity(BCVA), intraocular pressure(IOP), resolution of iris neovascularization and postoperative complications were followed up after the surgery, and all the cases were followed up 12mo.

RESULTS: Compared with preoperation(51.44±8.18 mmHg), IOP was significant decreased at 1, 7d, 1, 3, 6mo, 1a after surgery(25.94±11.82, 15.39±4.97, 15.94±2.69, 15.33±4.54, 18.89±7.95, 16.27±5.22 mmHg)(P<0.05). Last follow up after surgery, BCVA was improved in 12 eyes(67%), unchanged in 5 eyes(28%)and decreased in one eye. At 1a after operation, the complete success rate was 83%(15 eyes), conditional success rate was 11%(2 eyes), one eye of losing control of IOP was failed.

CONCLUSION: Conbercept intraocular injection combined with Ahmed valve implantation and phacoemulsification can not only effectively control postoperative IOP, but also improve the visual acuity of the patients as much as possible. It is an effective method for the treatment of NVG with cataract.
