OBJECTIVE: Cassiae Semen (CS, Juemingzi in Chinese) is a widely used traditional Chinese medicine with a variety of pharmacological effects. This study aimed to investigate the potential therapeutic effects and molecular mechanisms of anthraquinones of CS (AQS) for adiposity. METHODS: The chemical components of the AQS were determined using high-performance liquid chromatography (HPLC). Network pharmacology analysis was used to predict potential anti-obesity targets of action for AQS. We constructed high fat with high sugar water diet-induced obese mice and observed their body weight and whole-body lipid metabolism to evaluate the efficacy of AQS in promoting lipid metabolism. Subsequently, the epidermal temperature at the brown adipose tissue (BAT) before and after cold stimulation was observed and the expression of lipid metabolism-related genes in the liver and BAT tissues was detected to clarify the mechanism of action of AQS. RESULTS: Network pharmacology analysis showed that AQS was involved in the regulation of liver and adipose tissue function under obesity. Pathological and biochemical results showed that AQS reduced lipid accumulation in the liver and adipose tissue induced by an unhealthy diet. With the increase of cold tolerance, the volume and weight of BAT were increased by AQS, suggesting that it regulated the body heat production dominated by BAT. After AQS treatment, the levels of genes related to uncoupling protein1 (UCP1)-mediated adaptive thermogenesis in BAT tissues and lipid metabolism in the liver were also increased, which further proved that AQS activated BAT function to promote lipid metabolism in the whole body. CONCLUSION This study revealed the pharmacological effects of AQS, thereby providing a scientific basis for regulating BAT thermogenesis and liver lipid metabolism to alleviate obesity and providing clues for further exploring the application of natural active ingredients in the treatment of metabolism-related diseases.

Objective:To investigate the effect of goal setting theory-guided health management on disease cognition, compliance with antiviral therapy and self-efficacy of patients with chronic hepatitis B (CHB) so as to provide a theoretical basis for developing clinical nursing plans for patients with CHB.Methods:A quasi-experiment study was conducted, and 60 patients with CHB who were admitted to Anhui Provincial Hospital of Integrated Traditional Chinese and Western Medicine (the Third Affiliated Hospital of Anhui University of Chinese Medicine) from November 2022 to June 2023 were selected as the study subjects by convenience sampling method. They were randomly divided into the observation group and the control group by the envelope method, with 30 cases in each group. The control group received routine health management, and the observation group received goal setting theory-guided health management. Effects on disease cognition, compliance with antiviral therapy and self-efficacy of the two groups were analyzed.Results:There were 30 patients in each group completed the research. In the control group, there were 15 males, 15 females, aged (56.28 ± 5.97) years. In the observation group, there were 16 males, 14 females, aged (55.36 ± 6.21) years. After intervention, the scores for perceived benefit and acceptance [(20.36 ± 2.47) and (23.54 ± 2.67)] were higher than those of the control group [(16.33 ± 2.48) and (17.45 ± 2.68)], helplessness score of the observation group was (5.33 ± 0.67), lower than (10.21 ± 2.58) of the control group with significant differences ( t=6.31, 8.82, 10.03, all P<0.05). After intervention, compliance rate in the observation group [93.33% (28/30)] was higher than that in the control group [70.00% (21/30)], with significant difference ( χ2=5.46, P<0.05). After intervention, the General Self-Efficacy Scale score of the observation group was (31.25 ± 3.24), higher than (25.33 ± 2.67) of the control group, with significant difference ( t=7.72, P<0.05). Conclusions:Goal setting theory-guided health management can effectively improve compliance with antiviral therapy among patients with CHB, which may be related to the improvement of disease cognition and self-efficacy, and is worthy of clinical promotion.

Objective To investigate the effects of Semaglutide injection on glycolipid metabolism and adipokine levels in the treatment of type 2 diabetes mellitus(T2DM)patients with varying body mass index(BMI).Methods A total of 143 patients with T2DM admitted to our hospital between May 2022 and May 2024 were enrolled in this study.Based on their BMI,the patients were categorized into three groups:the normal-weight group(31 cases,18.5 kg/m2≤BMI<24 kg/m2),the super-recombinant group(49 cases,24 kg/m2≤BMI<28 kg/m2),and the obese group(63 cases,28 kg/m2≤BMI).28 kg/m2≤BMI).All participants received standard guideline-based conventional treatment and were additionally administered semaglutide injections for a duration of 12 weeks.The study compared glucose metabolism,islet β-cell function,lipid metabolism,body composition,adipokine levels before treatment and at 12 weeks post-treatment,as well as safety profiles during the treatment period across the three groups.Results After 12 weeks of treatment,the levels of fasting blood glucose(FPG),2-hour postprandial blood glucose(2 h PG),glycated hemoglobin(HbA1c),insulin resistance index(HOMA-IR),serum triglycer-ides(TG),total cholesterol(TC),and low-density lipoprotein cholesterol(LDL-C)decreased in all three groups.Specifically,the reductions were more pronounced in the obesity group compared to the normal group and the super-reorganization group,and the super-reorganization group showed intermediate reductions between the obesity and normal groups(P<0.05).Conversely,fasting C-peptide(FCP),2-hour postprandial C-peptide(2 h CP),irisin,adipsin,and omentin-1 levels increased in all three groups after treatment,with the greatest increases observed in the obesity group,followed by the super-reorganization group,both of which were significantly higher than the normal group(P<0.05).Additionally,high-density lipoprotein cholesterol(HDL-C)levels increased in all three groups after 12 weeks of treatment(P<0.05).BaselineBMI and total body fat mass(WBFM)were significantly higher in the obesity group compared to the super-reorganization group,which in turn were higher than the normal group(P<0.05).After treatment,BMI and WBFM decreased in both the obesity and super-reorganization groups,but remained significantly higher than in the normal group(P<0.05).The incidence of adverse reactions during treatment was 12.90％(4/31),10.20％(5/49),and 11.11％(7/63)in the normal,super-reorganization,and obesity groups,respectively,with no statistically significant differences among the groups(P>0.05).Conclusion Smiglutide injection can improve glucose and lipid metabolism,islet function,and adipokine levels in T2DM patients across different BMI categories,while also regulating body composition.It dem-onstrates a particularly strong improvement effect on glucose and lipid metabolism,islet function,and adipokine levels in overweight and obese T2DM patients.Additionally,smiglutide does not increase safety risks.

Objective To understand the epidemiological characteristics of road traffic accident injuries in Beijing can provide a theoretical basis for improving the pre-hospital emergency service capabilities and levels,and increasing patient survival rates while reducing disability,mortality rates.Methods A retrospective analysis was conducted on the medical records of 9207 patients who made pre-hospital emergency calls due to road traffic accident injuries at the Beijing Emergency Medical Center in 2023 to understand the patients' age,gender,injury time,injury location,injury degree and other characteristics.Results Traumatic diseases ranked first in the classification of emergency medical conditions in Beijing.Among them,road traffic accidents account for 37％.The ratio of male to female patients was 1.32∶1.The largest number of patients were aged 31-40,accounting for nearly 25％.The proportion of underage patients and those aged 71 and above was 12.16％.The differences in gender and age distribution were statistically significant,while the differences in gender distribution among different age groups were not statistically significant.Road traffic accident injuries occured most frequently in September and least in January.There were more cases in summer and autumn,and fewer in winter and spring.The most common injury sites in road traffic accidents were limbs/skin and head and neck,accounting for 81.06％.The patients with moderate severity of injuries were the most numerous,accounting for 85.29％.Conclusion To avoid road traffic accidents,prevention should be the priority.It is necessary to strengthen the joint governance of multiple departments and minimize the occurrence of road traffic accident from the source.Pre-hospital emergency care must focus on key populations and key seasons,strengthen professional skills training and resource allocation,ensure efficient and smooth connection between pre-hospital and in-hospital care.Popularize and publicize the importance of self-rescue and mutual rescue,promote first aid knowledge and skills training for the public,and create a social atmosphere where"rescue is right beside us".

Objective:To develop a nomogram model for predicting the risk of ventilator-associated pneumonia (VAP) in patients with mechanical ventilation (MV) and to validate the stability of the prediction performance of the model.Methods:The patients with MV admitted to the Department of Critical Care Medicine of General Hospital of Ningxia Medical University from January 2019 to December 2022 were retrospectively selected according to the order of admission. The patients with MV were divided into the non-VAP group and the VAP group according to whether VAP occurred. The clinical data of the two groups, including general information, disease, medication, condition, and operation-related indicators were collected as candidate predictors of the model for comparison. Multivariate logistic stepwise forward regression analysis was used to screen the predictors that finally entered the model, and a nomogram model was constructed. The model discrimination was evaluated by the area under the receiver operating characteristic curve (AUC), the diagnostic test results of the model at the predicted threshold were calculated, the Hosmer-Lemeshow test was used to evaluate the model fit, and the Bootstrap resampling was used 1 000 times for internal validation, and model calibration and clinical applicability were evaluated by calibration curve and decision analysis curve, respectively.Results:A total of 1 250 patients with MV were included, including 1 102 patients in the non-VAP group and 148 patients in the VAP group, and the prevalence of VAP was 11.8%. The detection of multidrug-resistant organisms, chronic kidney disease, brain injury, oxygenation index, the place of tracheal intubation, reintubation, use of bronchoscopy, use of antibiotics, and MV duration were model predictors of VAP. The AUC of the nomogram model was 0.917 (95% CI: 0.895-0.939), the maximum Youden index of 0.697 corresponded to a prediction threshold of 0.096. The model accuracy, sensitivity and specificity were 0.836, 0.865, and 0.832, respectively. The positive predictive value and the negative predictive value were 0.409 and 0.979, respectively. The Hosmer- Lemeshow test indicated that the model fit well ( P=0.938). The results of the internal validation of the model showed that the predicted risk of the calibration curve was generally consistent with the actual risk, and the decision threshold probability of the decision analysis curve ranged from 2% to 90%. Conclusions:The nomogram model developed in this study is simple, convenient and has relatively stable prediction performance, which can be externally validated to evaluate the extrapolation of the model, and provide a basis for individualized clinical prediction of the risk of VAP in patients with MV.

Diabetes of the exocrine pancreas(DEP) refers to a complication of diseases of the exocrine pancreas, associated with an increased risk of pancreatic cancer. Recent evidence has indicated that DEP, after type 2 diabetes, has become the second most common type of adults-onset diabetes, with a higher prevalence than type 1 diabetes. DEP is not a single condition but encompasses various exocrine pancreatic disorders that lead to hyperglycemia through different mechanisms, creating significant diagnostic and therapeutic challenges. This review examines the latest research on the risk factors and pathogenesis of DEP, aiming to provide insights to improve its clinical management strategies.

Objective:To investigate the relationship between the level of angiotensin Ⅱ type 1 receptor autoantibody (AT1-AA) in the uterine fluid and the thickness of endometrium in infertile women with chronic endometritis.Methods:A case-control study was conducted to select 122 patients who underwent hysteroscopy and endometrial tissue biopsy at Assisted Reproduction Center, Taiyuan Central Hospital due to infertility from March 2023 to January 2024 as the study subjects. According to the results of hysteroscopy and endometrial tissue biopsy, the patients were divided into 52 cases in the infertility group with normal endometrium (NE infertility group) and the chronic endometritis combined with infertility group (CE infertility group) with 70 cases. Enzyme-linked immunosorbent assay was used to detect the level of AT1-AA in uterine fluid of the two groups. General clinical data, AT1-AA absorbance value of uterine fluid and uterine related indexes of the two groups were analyzed, and the correlations between AT1-AA level and the variation of indexes were analyzed.Results:Gravidity (median: 1 vs 1; Z=7.029, P=0.030) and parity (median: 0 vs 0; Z=12.258, P=0.002) in CE infertility group were higher than those in NE infertility group. There was AT1-AA in the uterine fluid, and the level of AT1-AA in CE infertility group was significantly higher than that in NE infertility group (median: 2.07 vs 1.44; Z=3.099, P=0.029). The endometrial thickness of CE infertility group was lower than that of NE infertility group (median: 6.0 vs 7.0 mm; Z=-2.179, P=0.029), and there were no statistical differences in other indexes between the two groups (all P>0.05). Further correlation analysis showed that there were no correlation between the level of AT1-AA in uterine fluid and parity, endometrial thickness, gravidity in NE infertility group (all P>0.05). However, the level of AT1-AA in uterine fluid of CE infertility group was positively correlated with parity (Spearman′s r=0.339, P=0.004), and negatively correlated with endometrial thickness (Spearman′s r=-0.499, P<0.001), but not correlated with gravidity ( P>0.05). Conclusions:AT1-AA is present in the uterine fluid of infertile women. The elevated level of AT1-AA in uterine fluid of infertile women with CE is related to the thinning of the endometrium.
