As the number of patients with compromised immune function increases and fungal resistance develops, so does the risk of contracting deadly fungi in humans. Both fungi and humans are eukaryotes, so identifying unique targets for antifungal drug development is difficult. In addition, the existing antifungal drugs are limited by toxicity, drug interaction and drug resistance in practical application, which leads to the increasing incidence and fatal rate of fungal infections. Therefore, it is urgent to develop new antifungal drugs. The semi-synthetic technology using microbial fermentation products from natural sources as lead compounds has become the most used method in structural modification of antifungal drugs due to its advantages of few reaction steps and easy operation. This paper will introduce the current status of natural antifungal drugs in clinical use, as well as the latest progress in the research and development of new semi-synthetic antifungal drugs, and summarize their mechanism of action, structural modifications, advantages and disadvantages, so as to provide reference for the subsequent development of new antifungal drugs.

ObjectiveTo assess the availability of bronchodilators for treatment of chronic obstructive pulmonary disease (COPD) in community health service centers (CHCs) in Shanghai. MethodsOn the basis of previous research, the questionnaire was updated, and surveys were conducted from April to May 2023 in CHCs in Shanghai, with a focus on the availability of medications for COPD treatment. According to the National Basic Medical Insurance, Work Injury Insurance, and Maternity Insurance Drug List (2023 Edition), a total of 24 types of bronchodilators for COPD treatment were identified. The availability rates were used to assess the accessibility of specific drugs in CHCs, and the dispensing rates were used to evaluate the variety of these medications in CHCs. ResultsA total of 248 CHCs responded, with a response rate of 100.0%. Among them, a total of 232 CHCs (93.5%) were equipped with bronchodilators. In terms of availability rates, the availability rates for β2 adrenoreceptor agonists, muscarinic antagonists, combination drugs, and xanthines drugs were 86.3%, 52.0%, 52.4%, and 85.1%, respectively. Regional differences were observed, in that salbutamol/levalbuterol and budesonide-formoterol were less available in suburban CHCs, ipratropium bromide had lower availability in urban CHCs, and aminophylline was more available in suburban CHCs. Regarding the dispensing rates of the 24 types of bronchodilators for COPD treatment, the median of types equipped by CHCs was 5, with a total of 200 CHCs (80.6%) equipped with fewer than 7 types of bronchodilator drugs. ConclusionThe proportion of CHCs in Shanghai equipped with bronchodilators for COPD is relatively high. However, there exist problems such as limited variety of stocked medications, significant differences in the availability of different drugs, and regional imbalances in drug stocking. To improve the standardized diagnosis, treatment, and management of COPD patients, it is recommended to enhance the availability of COPD treatment medications in CHCs.

ObjectiveTo evaluate the clinical efficacy of Maxing Loushi decoction in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with phlegm turbidity obstructing lung syndrome, and to investigate its effects on inflammatory factors, immune function, and the programmed death-1(PD-1)/programmed death-ligand 1 (PD-L1) signaling pathway. MethodsA randomized controlled study was conducted, enrolling 90 hospitalized patients with AECOPD and phlegm turbidity obstructing lung syndrome in the Respiratory and Emergency Departments of Dongzhimen Hospital, Beijing University of Chinese Medicine, from April 2024 to December 2024. Patients were randomly assigned to a control group and an observation group using a random number table, with 45 patients in each group. The control group received conventional Western medical treatment, while the observation group received additional Maxing Loushi decoction for 14 days. Clinical efficacy, COPD Assessment Test (CAT) score, modified Medical Research Council Dyspnea Scale (mMRC), 6-minute walk test (6MWT), serum inflammatory factors, T lymphocyte subsets, and serum PD-1/PD-L1 levels were compared between the two groups before and after treatment. ResultsThe total clinical effective rate was 78.57% (33/42) in the control group and 95.35% (41/43) in the observation group, with the observation group showing significantly higher efficacy than that of the control group. The difference was statistically significant (χ2 = 5.136, P<0.05). After treatment, both groups showed significant reductions in CAT and mMRC scores (P<0.05, P<0.01) and significant increases in 6MWT compared to baseline (P<0.01). The observation group demonstrated significantly greater improvements than the control group in this regard. Levels of inflammatory markers including C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), monocyte chemoattractant protein-1(MCP-1), and macrophage inflammatory protein-1α (MIP-1α) were significantly reduced in both groups (P<0.05, P<0.01), with greater reductions in the observation group (P<0.05, P<0.01). CD8+ levels were significantly reduced (P<0.01), while CD3+, CD4+, and CD4+/CD8+ levels were significantly increased in both groups after treatment (P<0.05, P<0.01), with more significant improvements observed in the observation group (P<0.05, P<0.01). Serum PD-1 levels were reduced (P<0.05, P<0.01), and PD-L1 levels were increased significantly in both groups after treatment (P<0.05, P<0.01), with more pronounced changes in the observation group (P<0.05). ConclusionMaxing Loushi decoction demonstrates definite therapeutic efficacy as an adjunctive treatment for patients with AECOPD and phlegm turbidity obstructing lung syndrome. It contributes to reducing serum inflammatory factors, improving immune function, and regulating the PD-1/PD-L1 signaling pathway.

ObjectiveTo investigate and analyze an outbreak of rotavirus infectious diarrhea in a prison in Chongqing Municipality, to provide a basis for adult rotavirus surveillance and prevention, and to explore the public health problems in special settings. MethodsA retrospective survey was conducted to collect and analyze data on individual cases with diarrheal disease on-site. The clinical characteristics, as well as the temporal, spatial and geographical distribution patterns of the epidemic were described. Multi-pathogen detection tests were conducted both on diarrhea cases and environmental samples, with viral genotyping performed on positive samples. A case-control analysis was performed to identify the causes of the outbreak, and an SEIR model was adopted to predict the outbreak trend and evaluate the effectiveness of interventions. ResultsA total of 65 cases were found among the inmates, with an attack rate of 2.03%. The predominant clinical manifestations included diarrhea (89.23%), watery stool (73.85%), and dehydration (18.46%). The epidemic curve indicated a “human-to-human” transmission pattern, with an average incubation period of 5‒6 days. The attack rates among chefs in the main canteen (80.00%, 8/10) and caterers (28.33%, 17/60) were significantly higher than those of other inmates (P<0.05). Multi-pathogen polymerase chain reaction (PCR) testing detected positive for group A rotavirus, with the viral genotyping identified as G9P [8] strain. Factors such as unprotected "bare-handed" food distribution among cases with diarrhea (OR=9.512, 95%CI: 4.261‒21.234) and close contact with diarrhea cases (OR=3.656, 95%CI: 1.719‒7.778) were the possible cause of the outbreak. The SEIR model (r0=5, α=0.3, β1=0.08, β2=0.04) was constructed using prison inmates as susceptible population, aiming at fitting the initial transmission trend of the outbreak, and the epidemic rate declined rapidly after intervention measures were implemented (rt≈0). ConclusionThis rare rotavirus infection diarrhea outbreak among adults in confined settings suggests that the construction of public health prevention and control systems in prison may be overlooked. Cross infection during meal processing and distribution in the canteens of such settings is likely to be the cause of the outbreak. Given the potential neglect of public heath system construction in special settings, it is imperative to enhance the surveillance and monitoring of rotavirus and other intestinal multi-pathogens among adults, as well as the construction of public health prevention and control systems in these special settings.

ObjectiveTo investigate the high-risk detection rate and aggregation of cardiovascular diseases(CVD) in 8 districts of Shanghai and influencing factors, and to provide scientific references for prevention and control of CVD. MethodsBased on the Cardiovascular Disease Screening and Management Program in Shanghai from 2016 to 2021, 104 685 participants aged 35 to 75 in 8 districts of Shanghai were selected for analysis. χ2 test and multivariate logistic regression were used for statistical analysis of the influencing factors of CVD and aggregation of CVD. ResultsThe proportion of high-risk CVD individuals in the population was 19.17%, including the high-risk individuals with hypertension (8.65%), dyslipidemia (6.33%), CVD history (5.58%), and WHO assessed risk ≥20% types (2.69%), respectively. Old age, overweight and obesity, central obesity, smoking, drinking, farmers, unmarried, and low family income were the risk factors of CVD, while high education level was the protective factor. In the participants, 16 323 people (81.34%) were classified as CVD high-risk groups; The number of aggregation of 1, 2 and ≥3 high risk types of CVD were 16 323(81.34%), 3 236(16.13%), 509(2.54%), respectively. Old age, low education level, low annual family income, farmers, unmarried, smoking, drinking, overweight, obesity and central obesity were associated with the risk of aggregation of high risk types of CVD, and the correlation strength increased with the increase of aggregation types. ConclusionThe prevention and control of CVD in Shanghai should focus on the hypertension, elderly, overweight, obesity, central obesity, smoking, drinking, low educated, low family income, farmers and unmarried people, and targeted intervention measures should be taken to reduce the risk of CVD among residents.
