In recent years, the incidence of dry eye disease(DED)is increasing, positioning it as one of the most prevalent diseases affecting the ocular surface. Inflammatory response is the pathological basis of DED, involving various inflammatory mediators and inflammatory signaling pathways. Consequently, anti-inflammatory treatment emerges as a fundamental strategy for preventing and managing DED. This review summarizes the classic inflammatory factors involved in the development and progression of DED, including interleukins, tumor necrosis factor, matrix metalloproteinases, chemokines, and cell adhesion molecules. It also discusses the relevant inflammatory signaling pathways: the MAPKs pathway, NF-κB pathway, Wnt pathway and TLR pathway. Additionally, this review addresses the mechanisms of action and alterations in relevant biomarkers associated with current first-line recommended anti-inflammatory therapies, including corticosteroids, immunosuppressants, nonsteroidal anti-inflammatory drugs, and traditional Chinese medicine approaches to inflammation management. This comprehensive overview aims to enhance understanding of the inflammatory mechanisms underlying DED while exploring future therapeutic prospects.

OBJECTIVE To develop the quality evaluation standard indicator system for hospital cough and wheeze pharmaceutical care clinic (CWPC) pharmacist training within the layered learning practice model (LLPM), and apply it in clinical practice. METHODS Our teaching team established an LLPM model to train cough and wheeze pharmacists, according to the actual conditions of our college. Using qualitative interview methods, expert questionnaires were compiled with literature research; the expert correspondence methods were employed to conduct two rounds of consultation with 10 domestic respiratory medicine experts, thus constructing an evaluation index system for the teaching quality of cough and wheeze pharmacists. The experts’ positive coefficient, authority coefficient, Kendall’s harmony coefficient, and the degree of concentration of opinions were calculated. The analytic hierarchy process (AHP) was used to determine the weight of each indicator within the index system. From June 2023 to June 2024, the teaching team enrolled 21 pharmacists in the training program. The teaching team assessed and scored the trial group (LLPM) and control group (traditional teaching model) based on the benefit indicators for pharmacists and patients in the evaluation index system, and compared the results. RESULTS This study explored the establishment of a training system for cough and wheeze pharmacists under the LLPM model, and initially established an evaluation index system using the Delphi method. In two rounds of Delphi method questionnaires, the recovery rate was 100%, with an authority coefficient exceeding 0.8, Kendall’s harmony coefficient ranging from 0.235 to 0.459, and all P-values being less than 0.05. Four primary (comprising trainee feedback, learning gains, behavioral improvements, and training performance), 12 secondary and 33 tertiary indicators were finalized. In the empirical evaluation, the results of the two groups showed a significant benefit to the pharmacists in the trial group. Specifically, the percentage of patients receiving corticosteroids for COPD or wheeze service patients per month (80.5%), an average increase in the number of cough and wheeze team service outpatient visits per month (compared to the same period of the previous year) of 14.8 visits per month, and the patient satisfaction score (4.9) were all significantly higher than those in the control group (P<0.05). CONCLUSIONS The application of the LLPM in competency training for pharmacists specializing in cough and wheeze care yields multiple benefits and holds significant guiding value. The constructed training quality evaluation index system under this model is scientific and reliable.

Bisphenols (BPs) are extensively used in food packaging, personal care products, and plastics, making them prevalent in both living and working environments, which has raised significant concern. As endocrine-disrupting chemicals, BPs exert toxic effects on the female reproductive system by binding to estrogen receptors, thereby activating or inhibiting the expression of genes related to reproductive functions, which disrupts the normal function of the endocrine system. This paper reviewed the effects of bisphenol A (BPA), bisphenol S (BPS), and bisphenol F (BPF) on female reproductive function, focusing on three key aspects: the effects on the female reproductive organs, the occurrence of associated reproductive disorders, and the mechanisms of toxicity. Specifically, this review highlighted the effects on ovarian function, uterine morphology and function, and fallopian tube function, as well as their correlation with polycystic ovary syndrome, endometriosis, miscarriage, and eclampsia. Additionally, the toxic mechanisms of BPs exposure were summarized, providing a scientific basis for future research on the impact of BPs on the female reproductive system, as well as for the assessment of potential health risks and the development of preventive measures.

OBJECTIVE To explore the effects of multi-disciplinary comprehensive management team of tertiary hospital collaborated with the pharmacists from community health service center (hereinafter referred to as “community pharmacists”) on elderly patients with hypertension in the community. METHODS Elderly patients with hypertension from May 2020 to May 2021 in Yuhua Community Health Service Center of Nanjing were divided into control group (76 cases) and observation group (76 cases) according to the management style. The control group was treated with regular community medical services and the observation group received regular community medical services plus pharmaceutical care provided by the comprehensive management team collaborated with community pharmacists. The compliance, blood pressure control status and hypertension-related complications were compared between 2 groups before management and after 24 months of management. RESULTS After 24 months of management, the compliance and blood pressure compliance rates in both groups were higher than before management; meanwhile, the observation group was significantly higher than control group at the corresponding period (P<0.05 or P< 0.01). The blood pressure levels of both groups were significantly lower than before management, and the systolic blood pressure as well as the incidences of the whole complications and cerebrovascular injury in the observation group were significantly lower than control group at the 583867635@qq.com corresponding period (P<0.05). There was statistical significance in the effects of the rate of reaching the standard of blood pressure on the complications (P<0.01). CONCLUSIONS The hypertension management mode of comprehensive management team collaborated with community pharmacists can significantly improve the compliance and blood pressure compliance rate of elderly patients with hypertension, and reduce the incidence of hypertension-related complications.

Objective:To explore high-risk sexual behaviors of HIV/AIDS and related factors in young students in Guangzhou.Methods:A cross-sectional survey was conducted in 5 different types of Guangzhou colleges by convenience sampling with minimum number of classes per grade and 600 samples per school from September to November 2021. The R 4.2.2 software was used to consolidate databases. Simultaneously, a logistic regression model and a decision tree algorithm model, stratifying by whether sexual behaviors had occurred before, were constructed. In each layer, the prediction performance of the two models was evaluated through area under receiver operating characteristic and the confusion matrix, and then the model with high prediction performance was retained.Results:A total of 7 346 students were surveyed. The proportion of the respondents reporting sexual experience were 9.08% (667/7 346), in whom 26.24% (175/667) had risky sexual activity in the past year. The decision tree algorithm model performs well in predicting whether high-risk sexual behaviors have occurred in the past year. When the complexity parameter value is 0.018, and nsplit reaches 4, which means there are 5 leaf nodes in the model, the cross error of the tree will be the smallest. The first best grouping variable in the decision tree was whether to use condoms throughout the first sexual behavior. If condoms were used at their sexual debut, but homosexual practices have occurred in the past year, the probability of risky sexual behavior will increase. If homosexual practices have not occurred in the past year, but the age of sexual debut was below 18 years old while the period of HIV education was after high school, the probability of risk sexual behavior will also increase.Conclusions:AIDS-related risky behaviors of young students still deserved attention. The experience of sexual debut and whether AIDS-related health education has been received before the sexual debut were significant predictors for the occurrence of high-risk sexual behavior. The decision tree algorithm model has particular applicability for predicting and screening potential risk populations.

BACKGROUND:Animal models of diabetic encephalopathy that have been studied mainly include streptozotocin-induced model,high-sugar and high-fat diet-induced model and spontaneous animal model.Establishing a simple,easy,short-cycle,safe and effective model of diabetic encephalopathy can help to explore the subsequent pathogenesis and screen therapeutic drugs. OBJECTIVE:To further explore and evaluate the method of building diabetic encephalopathy rat models. METHODS:Twenty Sprague-Dawley rats were randomly divided into control(n=10)and model(n=10)groups.Rats in the model group were given a single injection of 45 mg/kg streptozotocin in the left lower abdominal cavity,and those in the control group were given the same amount of citrate buffer.During the experiment,the body mass,feed intake,water intake and blood glucose were measured.After 8 weeks,the glucose tolerance and oxidative stress levels were measured,and the pathological changes of brain tissue and the expression of apoptotic proteins were compared between groups. RESULTS AND CONCLUSION:Compared with the control group,the food intake,water intake,encephalization quotient,blood glucose and area under the blood glucose curve were significantly increased in the model group,while the body mass decreased significantly(P<0.01).Histopathological examination of the brain showed that compared with the control group,the number of surviving nerve cells was significantly reduced in the model group(P<0.01),with more significant pathological damage of nerve cells.Compared with the control group,the activities of serum superoxide dismutase,catalase and glutathione in the model group were significantly decreased(P<0.01),and the content of oxidative malondialdehyde was significantly increased(P<0.05).The expression levels of apoptosis-related proteins Bax and Caspase-3 in brain tissue increased in the model group compared with the control group,while the expression of Bcl-2 decreased(P<0.01).In conclusion,an 8-week injection of 45 mg/kg streptozotocin can cause obvious pathological damage to the brain tissue of diabetic rats,to successfully establish the rat model of diabetic encephalopathy.

BACKGROUND:Due to the young age of children,the occipital condyle and foramen magnum are not fully developed,and they are prone to various diseases and injuries in the occipitocervical junction,which requires surgical treatment in severe cases.However,anatomical parameters for the development of the occipital condyle and foramen magnum in children are lacking. OBJECTIVE:To measure the morphological structure of the occipital condyle and foramen magnum by three-dimensional reconstruction technique,and to provide important anatomical parameters for occipitocervical junction lesions,related surgical procedures and forensic identification. METHODS:Imaging data of 389 cases of primitive children and adolescents involved in skull base undergoing spiral CT scanning(247 males and 142 females)aged 1-18 years were collected and divided into 1-3-year-old group,4-6-year-old group,7-9-year-old group,10-12-year-old group,13-15-year-old group,and 16-18-year-old group according to their age.Mimics 16.0 software was used to reconstruct the skull base and measure the length and width of the foramen magnum.A formula was used to calculate the area and index of the foramen magnum.We measured the length,width and height of the occipital condyle,the angle between the long axis and the sagittal axis of the occipital condyle(O-S angle),the included angle between the midpoint of the front and back edges of the foramen magnum and the connection between the back edge of occipital condyle and the intersection point of the foramen magnum(F-O angle),and the included angle between the midpoint of the front and back edges of the foramen magnum and the midpoint of the back wall of the sublingual neural tube(F-H angle).Gender,side and age differences were analyzed among the indicators. RESULTS AND CONCLUSION:(1)In foramen magnum measurement,there was no significant difference between sexes in the index of the foramen magnum(P>0.05),but there were significant differences in length,width and area of the foramen magnum(P<0.05).(2)The O-S angle,F-O angle and F-H angle of the occipitral condyle were not significantly different between genders(P>0.05),but length,width and height of the occipital condyle were significantly different between genders(P<0.05).(3)There were no significant differences in the length of the occipital condyle among different groups(P>0.05),but there were significant differences in the width and height of the occipital condyle,O-S angle,F-O angle and F-H angle among different groups(P<0.05).(4)Length,width and area of the foramen magnum,length,width and height of the occipital condyle showed a wavy increasing trend with the increase of age,while O-S,F-O and F-H angles showed a wavy decreasing trend with the increase of age,while the index of the foramen magnum showed no significant change.(5)In conclusion,there are gender and lateral differences in the morphological indexes of the foramen magnum and the occipital condyle in children.These differences can provide an important reference for clinical surgical approach selection and forensic examination.
