ObjectiveTo observe the clinical effectiveness and safety of Qingfei Shenshi Decoction (清肺渗湿汤) combined with western medicine for patients with bronchial asthma of heat wheezing syndrome, and to explore its potential mechanism of action. MethodsEighty-six participants with bronchial asthma of heat wheezing syndrome were randomly divided into treatment group and control group, each group with 43 participants. The control group received conventional western medicine, and the treatment group was additionally administered Qingfei Shenshi Decoction orally on the basis of the control group, 1 dose per day. Both groups were treated for 14 days. The primary outcome measure was clinical effectiveness; secondary outcome measures included traditional Chinese medicine (TCM) syndrome score, asthma control test (ACT) score, pulmonary function indices such as forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF), serum inflammatory factor levels including interleukin-4 (IL-4), tumour necrosis factor-α (TNF-α), and high-sensitivity C-reactive protein (hs-CRP), and immune function indices including CD3+, CD4+, CD8+, CD4+/CD8+. All outcome measures were evaluated before and after treatment. Vital signs were monitored, and electrocardiography, blood routine, urine routine, liver function, and renal function tests were performed before and after treatment. Adverse events and reactions during the study were recorded. ResultsA total of 80 patients completed the trial with 40 in each group. The total clinical effective rate of the treatment group was 97.5% (39/40), which was significantly higher than that of the control group (85.0%, 34/40, P<0.05). After treatment, both groups showed decreased TCM syndrome scores, IL-4, TNF-α, hs-CRP, and CD8+ levels, as well as increased ACT scores, CD3+, CD4+, CD4+/CD8+, FEV1, FVC, and PEF levels (P<0.05 or P<0.01). Moreover, the improvements in these indices were more significant in the treatment group than in the control group (P<0.05 or P<0.01). No significant abnormalities in safety indicators were observed in either group, and no adverse events or reactions occurred. ConclusionQingfei Shenshi Decoction combined with conventional western medicine for patients with bronchial asthma of heat wheezing syndrome can effectively improve the clinical symptoms, pulmonary function, and clinical effectiveness, with good safety. Its mechanism may be related to reducing inflammatory factor levels and regulating T lymphocyte subsets to improve immune function.

Background Against the background of global warming, frequent heatwaves pose a major threat to public health. Objective To investigate the effects of heatwaves on outpatient visits for skin diseases in Urumqi, characterize the exposure–response relationship, identify the critical temperature threshold, and provide scientific evidence for targeted prevention and control of heat-related skin diseases. Methods Data on meteorological conditions, air quality, and dermatological outpatient visits from 10 hospitals in Urumqi were collected from January 1, 2016 to December 31, 2024. A time-stratified case-crossover design combined with a distributed lag model was adopted to construct a conditional logistic regression model, with adjustment for potential confounders, including relative humidity, air pollutants, and COVID-19 lockdown measures. With a maximum lag of 14 d, single-lag and cumulative-lag effects of heatwaves were examined, and the exposure–response relationship between temperature and the risk of dermatological outpatient visit was fitted. Results A total of 385 heatwave days were identified in Urumqi from January 1, 2016 to December 31, 2024. These days were concentrated between June and September and showed an increasing annual trend. The median daily number of dermatological outpatient visits during heatwave periods (165 cases) was significantly higher than that during control periods (114 cases) (Z=−5.108, P<0.001). After adjusting for confounders, the odds of dermatological outpatient visits during heatwaves were 1.088 times higher than those of the control period (OR=1.088, 95%CI: 1.069, 1.107). Single-lag effects were statistically significant from lag0 to lag11 (P<0.05), peaking at lag0 (OR=1.088, 95%CI: 1.069, 1.107), showing an acute and immediate effect. Cumulative-lag effects were statistically significant from 1 to 14 d (P<0.05), peaking at lag04 (OR=1.117, 95%CI: 1.099, 1.136). The exposure–response relationship indicated that the OR values increased steeply with increasing temperature when the daily mean temperature exceeded 24.2 ℃, peaking at approximately 28.1 ℃ (OR=1.400, 95%CI: 1.189, 1.649). Conclusions Heatwave exposure is significantly associated with an increased risk of dermatological outpatient visits among residents in Urumqi. The impact of high temperature on skin diseases is predominantly acute, with peak risks observed on the day of exposure and within the subsequent 4 d. A daily mean temperature of 24.2 ℃ can serve as the critical threshold for heightened dermatological consultation risk. Strengthened health education and early warning systems are recommended to mitigate heatwave-related adverse dermatological outcomes.

ObjectiveTo optimize Tusizi prescription for ovarian reserve function based on the uniform design method combined with in vitro experiments and explore the underlying mechanisms of this prescription. MethodsThe uniform design method was adopted to design a 5-factor 11-level experiment on the water extract of Tusizi prescription. The cell-counting kit-8 (CCK-8) assay was employed to measure the viability of human ovarian granulosa cells (KGN cells) treated with Tusizi prescription extracts 1-11, and multivariate regression analysis was performed to determine the optimal herb ratio in this prescription. The potential targets of active ingredients in the prescription were retrieved from traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) and encyclopedia of traditional Chinese medicine (ETCM). The common targets shared by Tusizi prescription and diminished ovarian reserve (DOR) were selected and imported into search tool for the retrieval of interacting genes/proteins (STRING) to construct a protein-protein interaction (PPI) network and into gene function annotation database (DAVID) for gene ontology (GO) analysis. The CCK-8 assay was used to measure the viability of ovarian germline stem cells treated with hyperoside. The CCK-8 assay, 5-ethynyl-2'-deoxyuridine (EdU) staining, terminal-deoxynucleoitidyl transferase mediated nick-end labeling (TUNEL), and enzyme-linked immunosorbent assay (ELISA) were employed to examine the proliferation, apoptosis, and estradiol (E2) secretion of KGN cells treated with the water extract 11 of Tusizi prescription (Cuscutae Semen-Lycii Fructus-Dioscoreae Rhizoma-Poria-Nelumbinis Semen 4∶4∶2∶1∶1) and the optimal prescription screened by uniform design. On this basis, the optimal prescription composition for maximizing the effect on ovarian reserve function was determined and preliminary insights into the underlying mechanisms of this prescription were gained. ResultsA total of 147 common targets were obtained from 278 targets of Tusizi prescription and 1 721 targets of DOR. GO analysis revealed 194 biological processes, primarily involving cellular responses to exogenous compound stimuli, negative regulation of apoptotic process, and positive regulation of cell proliferation. It identified 84 cellular components, including cell membrane, mitochondria, and neuronal cell body, as well as 144 molecular functions such as enzyme binding, estrogen response element binding, and nuclear estrogen receptor binding. The multivariate regression analysis revealed that when Tusizi prescription was composed of Cuscutae Semen, Lycii Fructus, Dioscoreae Rhizoma, Poria, and Nelumbinis Semen in a ratio of 27∶30∶17∶12∶14, the water extract of Tusizi prescription had the best effect of enhancing the viability of KGN cells. CCK-8 results showed that compared with the normal group, the hyperoside group demonstrated increased viability of ovarian germline stem cells (P<0.01). The CCK-8, EdU, and ELISA results showed that compared with the normal group, the optimal prescription screened by uniform design and the water extract 11 of Tusizi prescription increased the proliferation and reduced the apoptosis of KGN cells (P<0.05, P<0.01). ELISA results showed that compared with the normal group, the water extract 11 of Tusizi prescription promoted the E2 secretion of KGN cells (P<0.05), while the optimal prescription screened by uniform design had no significant effect on the E2 secretion. ConclusionBoth the water extract 11 of Tusizi prescription (Cuscutae Semen-Lycii Fructus-Dioscoreae Rhizoma-Poria-Nelumbinis Semen 4∶4∶2∶1∶1) and the optimal prescription screened by uniform design (Cuscutae Semen-Lycii Fructus-Dioscoreae Rhizoma-Poria-Nelumbinis Semen 27∶30∶17∶12∶14) can improve the ovarian reserve function, and the former has better effect. Tusizi prescription can modulate biological processes (such as cell proliferation and apoptosis) and molecular functions (such as enzyme binding and estrogen response element binding) through active components like hyperoside to promote the proliferation and E2 secretion and inhibit the apoptosis of KGN cells, thereby protecting the ovarian reserve function.
