ObjectiveTo investigate the possible mechanism of Pibai Yucuo Formula （枇柏愈痤方， PYF） in treating acne from the perspective of skin barrier damage. MethodsThirty-two mice were randomly divided into blank group， model group， minocycline group， and PYF group， with 8 mice in each group. Except for the blank group， mice were induced by intradermal injection of Cutibacterium acnes （C.acnes） combined with topical application of artificial sebum to establish acne model. The blank group and model group received intragastric administration of 0.2 ml of distilled water， while the PYF group received intragastric administration of 22.75 g/（kg·d）of PYF， and the minocycline group received 0.013 g/（kg·d）of minocycline suspension， all once daily for 5 consecutive days. On day 0 and day 6 of the experiment， the body weight of mice in each group was recorded， and the absolute value of the body weight difference during the experiment was calculated. Skin conditions were assessed with multifunctional skin imaging system on the 2nd， 4th and 6th day of the experiment. Skin barrier function indicators including transepidermal water loss （TEWL）， and the water content of the stratum corneum and epidermis on day 0， 2， 4 and 6 of the experiment. Optical coherence tomography （OCT） was used to observe stratum corneum and skin thickness on the 1st， 3rd and 5th day of the experiment. Hematoxylin-eosin （HE） staining was performed to observe histopathological changes， while ELISA was used to detect interleukin-17A （IL-17A） levels， and immunofluorescence staining was used to assess skin barrier-related proteins filaggrin （FLG） and loricrin （LOR） levels of skin lesions on day 6 of the experiment. ResultsCompared to the blank group， the model group showed a decrease in body weight on day 6， and an increase in the absolute value of the difference in body weight before and after the experiment （P＜0.05）. On day 4 and 6， TEWL values increased， while water content in the skin stratum corneum and epidermis decreased （P＜0.05）， accompanied by elevated IL-17A level and reduced immunofluorescence intensity of FLG and LOR proteins （P＜0.05）. The model group mice showed papules or pustules at the skin modeling site with progressively worsening desquamation under multifunctional skin imaging system. OCT revealed focal epidermal protrusions， blurred epidermal-dermal boundaries， and disorganized structural layers. HE staining showed significant epidermal hyperkeratosis and incomplete keratinization in the skin， with keratin plug formation in hair follicles and glandular lumens， thickened stratum corneum， hyperplasia of the stratum spinosum， as well as dense dermal inflammatory cell infiltration， and capillary dilation. Compared to the model group， both the minocycline group and the PYF group showed a reduced difference in body weight before and after experiment （P＜0.05）. On day 4 and 6， the TEWL value decreased， and water content of the skin stratum corneum increased （P＜0.05）； on day 6， the IL-17A level in the skin lesions decreased and immunofluorescence intensity of FLG and LOR proteins increased （P＜0.05）. On day 4 and 6， the severity of the skin lesions and range of redness and swelling were lighter than those in the model group， with reverted epidermal thickness， smoother surface and clearer epidermis-dermis boundary. HE staining showed that the degree of skin keratinization was reduced， and the inflammatory infiltration and vascular dilation in the dermis were improved compared to the model group. The PYF group showed better results than the minocycline group in reducing TEWL value on day 4 （P＜0.05）. ConclusionPYF may improve inflammation and skin barrier damage by downregulating IL-17A levels in lesion tissue and increasing skin barrier-related proteins， which could be one of the potential mechanism of action on acne.

OBJECTIVE To understand the changing trends of use of antibiotics and etiological submission rates in medical institutions of Wuhan and find out the key points of management.METHODS The survey data of Wuhan were collected from the cross-sectional survey databases for nosocomial infections in China of 2016,2018,2020 and 2022,and the data were retrospectively analyzed.RESULTS From 2016 to 2022,a total of 141 284 hospital-ized patients from 117 medical institutions were enrolled in the survey,and the utilization rate of antibiotics was 32.36％;the utilization rate of antibiotics was 32.87％in 2016,31.74％in 2018,28.75％in 2020,34.56％in 2022,showing an upward trend(x2=13.941,P＜0.001).The utilization rates of antibiotics were relatively high in respiratory medicine department and comprehensive ICU,which showed upward trends(x2=16.377,P＜0.001;x2=5.581,P=0.018);the utilization rate of antibiotics showed a downward trend in non-neonates pediatrics de-partment(x2=11.886,P＜0.001).The rates of prophylactic use of antibiotics for type Ⅰ incision surgery were 31.54％,23.53％,28.44％and 13.24％,respectively,showing downward trends(x2=230.333,P＜0.001).The etiological submission rates were 59.98％,55.77％,65.69％and 59.16％,respectively,which were basically same(P=0.072);the etiological submission rates of the medical institutions with less than 300 beds and 300 to 599 beds showed upward trends,while the etiological submission rates of the medical institutions with 600 to 899 beds and no less than 900 beds showed downward trends(x2=42.019,P＜0.001;x2=4.599,P=0.032).The etiological submission rate was 44.87％in 2018 before the treatment with antibiotics,47.80％in 2020,44.45％in 2022,which were basically same(P=0.431);the etiological submission rate of the medical institutions with no less than 900 beds showed a downward trend(x2=14.464,P＜0.001).CONCLUSIONS The use of antibiotics of the hospi-talized patients is generally normalized in the medical institutions of Wuhan,the utilization rate shows an upward trend,the etiological submission rate is basically same,and the rate of prophylactic use of antibiotics for type Ⅰincision surgery shows a downward trend.It is necessary to attach great importance to the etiological submission of large scale metical institutions before the treatment with antibiotics and the use of antibiotic of some key departments.

Objective:To develop the Home-based Self-management Efficacy Questionnaire for Stable Chronic Obstructive Pulmonary Disease (COPD) Patients and test its reliability and validity.Methods:Guided by the individual and family self-management theory and self-management efficacy theory, a preliminary questionnaire was developed through literature analysis, semi-structured interviews, and expert inquiries. From September to November 2022, convenience sampling was used to select stable COPD patients of the Respiratory Department of Tongji University Shanghai Pulmonary Hospital as participants for investigation for project analysis and exploratory factor analysis of the questionnaire. From December 2022 to January 2023, a survey was conducted on stable COPD patients who visited the Respiratory Department of Tongji University Shanghai Pulmonary Hospital and Yancheng Third People's Hospital to conduct confirmatory factor analysis and reliability testing on the questionnaire.Results:A total of 220 and 290 questionnaires were distributed respectively, and 214 and 280 valid questionnaires were collected, with effective response rates of 97.27% (214/220) and 96.55% (280/290), respectively. The Home-based Self-management Efficacy Questionnaire for COPD Patients included six dimensions and 28 items. The questionnaire's total Cronbach's α coefficient was 0.910, and the half-confidence coefficient was 0.806. The content validity index at the questionnaire level was 0.928, and the content validity index at the item level was 0.800 to 1.000. The exploratory factor analysis showed that a total of six common factors were extracted, with a cumulative variance contribution rate of 63.943%. Confirmatory factor analysis showed that the model fitted well and the questionnaire factor structure was stable.Conclusions:The the Home-based Self-management Efficacy Questionnaire for Stable COPD has been developed with good reliability and validity, providing a reference for medical and nursing staff to evaluate the home self-management efficacy of stable COPD patients.

Objective:To establish an evaluation index system for patient safety education targeted at undergraduate nursing interns.Methods:Based on the CIPP (Context, Input, Process, Product) evaluation model, a preliminary draft of the index system was developed using a literature review and semi-structured interviews. The Delphi method and the Analytic Hierarchy Process were applied to finalize the index system.Results:Two rounds of Delphi expert consultation were conducted. In the first round, 23 questionnaires were distributed, and 20 valid responses were received (effective response rate: 86.96%) . Among them, 15 experts (75.00%) provided revision suggestions. In the second round, 20 questionnaires were distributed, and 19 valid responses were received (effective response rate: 95.00%) , with two experts (10.53%) offering suggestions. The expert authority coefficients for the two rounds were 0.900 and 0.921, respectively. Kendall's coordination coefficients were 0.272 and 0.273 ( P<0.01) . The final evaluation system consisted of four first-level indicators, eight second-level indicators, and 18 third-level indicators. Conclusions:The evaluation index system constructed in this study is scientifically grounded and reliable. However, its practical utility and applicability require further validation.

Background and Aims:Elderly patients undergoing laparoscopic radical resection of colon cancer often experience decreased sleep quality,which may hinder postoperative recovery.Although pharmacological interventions are commonly used in clinical practice to improve postoperative sleep,conventional medications may lead to adverse effects such as delirium and dependence.This study aimed to evaluate the effect of a non-pharmacological intervention—buccal acupuncture combined with ultrasound-guided stellate ganglion block(SGB)—on postoperative sleep quality in elderly patients.Methods:A total of 60 elderly patients who underwent laparoscopic radical resection of colon cancer at the Forth Hospital of Changsha from February to August 2024 were enrolled.Using a random number table,the patients were divided into two groups:30 in the control group(SGB alone)and 30 in the study group(SGB combined with buccal acupuncture).Perioperative mean arterial pressure(MAP),heart rate(HR),postoperative visual analogue scale(VAS)scores,Pittsburgh Sleep Quality Index(PSQI)scores,and the incidence of adverse events were recorded and analyzed.Results:There were no statistically significant differences in baseline characteristics between the two groups(all P>0.05).The study group showed significantly lower intraoperative and postoperative HR and MAP compared to the control group(all P<0.05).VAS scores at 6,24,and 48 h postoperatively,as well as PSQI scores on postoperative days 1,3,and 5,were significantly lower in the study group(all P<0.05).Additionally,the incidence of drowsiness was significantly reduced(P<0.05).No significant differences were found between the two groups in terms of nausea,vomiting,or agitation(all P>0.05).Conclusion:The combination of buccal acupuncture and SGB during the perioperative period can effectively improve postoperative sleep quality,alleviate pain,and reduce adverse reactions in elderly patients undergoing laparoscopic radical resection of colon cancer.This safe and effective non-pharmacological intervention holds promising clinical application value.

To investigate the protective effects and underlying mechanisms of Qin-Zhu-Liang-Xue decoction (QZLX) in atopic dermatitis (AD) and glucocorticoid resistance, we conducted a single-blinded, randomized controlled clinical trial to evaluate the efficacy and safety of this concoction. Network pharmacology analysis was performed and validated through clinical studies. The efficacy, safety, and mechanism of action of QZLX and glucocorticoid receptor (GR) α recombinant protein were assessed in AD mice induced by 2,4-dinitrofluorobenzene (DNFB). Correlation analysis was performed to determine the clinical relevance of GRα. The trial demonstrated that patients who received QZLX showed considerable improvements in their Scoring Atopic Dermatitis (SCORAD) and Dermatology Life Quality Index (DLQI) scores compared with those who received mizolastine at week 4. Network pharmacological analysis identified GRα as a key target for QZLX in AD treatment. QZLX administration increased the serum GRα expression in AD patients, alleviated AD symptoms in mice, decreased inflammatory cytokine expression, and increased GRα expression without affecting liver or kidney function. In addition, GRα recombinant protein improved AD-like skin lesions in DNFB-induced mice. A negative correlation was observed between GRα expression and clinical parameters, including SCORAD, DLQI, and serum IgE levels. QZLX alleviates AD symptoms through the upregulation of GRα and thus presents a novel therapeutic strategy for the prevention of glucocorticoid resistance in AD management.
