Objective To analyze the situation of rapid antiretroviral therapy (ART) and death of HIV/AIDS in Wuhan from 1994 to 2023, and to provide a scientific basis for further rapid initiation of ART and reduction of mortality rate. Methods According to the case follow-up and treatment database of China AIDS Prevention and Control Information System, data were obtained from all the cases reported from January 1, 1994 to December 31, 2023 with the current address in Wuhan City and the review status of the final review card. The data were analyzed using Kaplan-Meier and Cox proportional hazards models. Results The total mortality rate of HIV/AIDS in Wuhan from 1994 to 2023 was 12.76%. The proportion of receiving antiretroviral therapy within 30 days increased year by year, and the mortality rate decreased year by year. After adjusting for sex, age, occupation, ethnicity, education level, mobile population, history of STD, route of infection, source of sample, and first CD4 value, receiving antiretroviral therapy within 30 days (HR=0.08, 95%CI: 0.07-0.10) was a protective factor for HIV/AIDS mortality. Conclusion Rapid antiretroviral therapy can significantly reduce the risk of HIV/AIDS death. A sustainable model of rapid initiation of antiretroviral therapy should be further established to increase the proportion of rapid antiretroviral therapy for HIV/AIDS in Wuhan.

Objective To explore the delirium incidence and risk factors among patients undergoing abdominal surgery in the post-anesthesia care unit(PACU),and establish a column chart prediction model.Methods A total of 1851 patients who underwent abdomi-nal surgery,with a surgery duration exceeding 4hours and were routinely transferred to the PACU after surgery in the First Affiliated Hos-pital of Wenzhou Medical University from January 2022 to December 2023 were selected.The patients were divided into a delirium group and a non-delirium group based on a nursing delirium screening scale score≥2.The relative factors of before and during the surgery were analyzed retrospectively.The LASSO regression was used to screen the variables,and the independent influencing factors were deter-mined using univariate and multivariate Logistic regression before creating a forest plot.The predictive efficacy of the column chart predic-tion model was evaluated by area under the curve(AUC)of receiver operating characteristic(ROC)and the Hosmer-Lemeshow test.Results A total of 113(6.1％)patients experienced delirium in the PACU.The result of the multivariate Logistic regression analysis in-dicated that gender,age,flurbiprofen,hypotension,hypothermia,hypercapnia,and surgery duration were independent influencing factors for delirium in the PACU,while a long surgery duration and using flurbiprofen were protective factors.The nomogram model was construc-ted based on the result and the AUC value of this model was 0.738.The Hosmer-Lemeshow goodness-of-fit test for the model demon-strated a good fit(P=0.686).Conclusion Medical staff should enhance intraoperative management,ensure sufficient analgesia,main-tain hemodynamic stability,reduce the incidence of intraoperative adverse events,pay attention to elderly male patients,and decrease the occurrence of delirium in the PACU.

Objective:To investigate the impact of antenatal corticosteroid (ACS) exposure on neonatal outcomes in late preterm infants.Methods:This retrospective cohort study analyzed 406 late preterm infants (gestational age 34 +0-36 +6 weeks) born at Tongji University Affiliated Dongfang Hospital between January 2021 and June 2024. Participants were divided into ACS-exposed ( n=254) and control ( n=152) groups. Maternal characteristics, neonatal profiles, and outcomes [respiratory disorders (respiratory distress syndrome, respiratory failure, bronchopulmonary dysplasia), neonatal hypoglycemia, and early-onset sepsis] were compared. And they were stratified by plurality (154 twins, 252 singletons) and gestational age (96 at 34 +0-34 +6 weeks; 111 at 35 +0-35 +6 weeks; 199 at 36 +0-36 +6 weeks), the effects of ACS exposure on neonatal outcomes were analyzed. Late preterm infants were also divided into affected ( n=13) and unaffected ( n=393) groups according to whether they had respiratory disorders, and the risk factors of respiratory disorders were analyzed. Statistical methods included independent t-test, Mann-Whitney U, Chi-square test, and multivariate logistic regression. Results:The ACS-exposed group exhibited significantly higher rates of assisted reproductive technology conception [53.1% (135/254) vs. 37.5% (57/152), χ2=9.37], twin pregnancy [43.3% (110/254) vs. 28.9% (44/152), χ2=6.84], cesarean delivery [83.5% (212/254) vs. 66.4% (101/152), χ2=15.66], and neonatal intensive care unit admission than those in the control group [59.1% (150/254) vs. 40.8% (62/152), χ2=12.61] (all P<0.05). No significant differences emerged between ACS-exposed and control groups in respiratory disorders [3.1% (8/254) vs. 3.3% (5/152), χ2=0.01], early-onset sepsis [1.6% (4/254) vs. 1.3% (2/152), χ2=0.71], or neonatal hypoglycemia [1.6% (4/254) vs. 1.3% (2/152), χ2=0.71] (all P>0.05). Stratified analyses by plurality or gestational age strata revealed no significant differences in respiratory disorders, early-onset sepsis or neonatal hypoglycemia between ACS-exposed and control groups (all P>0.05). Multivariate logistic regression identified ACS exposure as non-protective against respiratory disorders ( OR=0.37, 95% CI: 0.10-1.39, P=0.144), with maternal glucose metabolism disorders (pre-gestational/gestational diabetes) as a risk factor ( OR=5.26, 95% CI: 1.57-17.71, P=0.007) and higher gestational age as protective ( OR=0.34, 95% CI: 0.15-0.78, P=0.012). Conclusions:ACS administration at 34 +0-36 +6 weeks demonstrated no significant benefits for preventing respiratory disorders in late preterm infants and did not increase risks of hypoglycemia or early-onset sepsis. Maternal glucose dysregulation and lower gestational age elevate respiratory morbidity risk in this population.

ObjectiveTo investigate the mechanism of ferroptosis mediated by long-chain acyl-CoA synthetase 4 （ACSL4） signalling pathway in rats with coronary heart disease with blood stasis syndrome and the intervention effect of Xuefu Zhuyutang. MethodsSPF male SD rats were randomly divided into normal group， sham-operation group， model group， trimetazidine group （5.4 mg·kg^-1）， low-， medium-， and high-dose group （3.51， 7.02，14.04 g·kg^-1） of Xuefu Zhuyutang. The coronary artery left anterior descending ligation method was used to prepare a model of coronary heart disease with blood stasis syndrome， and continuous treatment for 7 d was conducted， while the sham-operation group was only threaded and not ligated. The general macroscopic symptoms of the rats were observed， and indicators such as electrocardiogram， echocardiography， and blood rheology were detected. The pathological morphology of myocardial tissue was observed by hematoxylin-eosin （HE） staining， and the changes in mitochondria in myocardial tissue were observed by transmission electron microscopy. The level of iron deposition in myocardial tissue was observed by Prussian blue staining. The levels of 12-hydroxyeicosatetraenoic acid （12-HETE） and 15-HETE were detected in serum by enzyme-linked immunosorbent assay. A biochemical colourimetric assay was used to detect the levels of Fe²⁺， lipid peroxidation （LPO）， glutathione （GSH）， and T-GSH/glutathione disulfide （GSSG） in myocardial tissue. DCFH-DA fluorescence quantitative assay was employed to detect the levels of reactive oxygen species （ROS）. Western blot and Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was adopted to detect the protein and mRNA expressions of glutathione peroxidase 4 （GPX4）， ferritin heavy chain 1 （FTH1）， ACSL4， and ly-sophosphatidylcholine acyltransferase3 （LPCAT3） in myocardial tissue. ResultsCompared with those in the normal group， the rats in the model group were poor in general macroscopic symptoms. The electrocardiogram showed widened QRS wave amplitude and increased voltage， bow-back elevation of the ST segments， elevated T waves， J-point elevation， and accelerated heart rate. Echocardiography showed a significant reduction in left ventricular ejection fraction （LVEF） and left ventricular fraction shortening （LVFS） （P<0.01）. Blood rheology showed that the viscosity of the whole blood （low， medium， and high rate of shear） was significantly increased （P<0.01）. HE staining showed an abnormal structure of myocardial tissue. There was a large area of myocardial necrosis and inflammatory cell infiltration and a large number of connective tissue between myocardial fibers. Transmission electron microscopy showed that the mitochondria were severely atrophy or swelling. The cristae were reduced or even broken， and the matrix was flocculent or even vacuolated. Prussian blue staining showed that there were a large number of iron-containing particles， and the iron deposition was obvious. The content of 12-HETE and 15-HETE in the serum was significantly increased （P<0.01）. The content of Fe²⁺， LPO， and ROS in myocardial tissue was significantly increased （P<0.01）. The content of GSH was significantly decreased （P<0.01）， and T-GSH/GSSG was decreased （P<0.01）. The protein and mRNA expressions of GPX4 and FTH1 in myocardial tissue were both significantly decreased （P<0.05， P<0.01）， while those of ACSL4 and LPCAT3 increased significantly （P<0.01）. Compared with the model group， the general macroscopic symptoms and electrocardiogram results of rats in low-， medium- and high-dose groups of Xuefu Zhuyutang were alleviated， and the differences in LVEF/LVFS ratios were all significantly increased （P<0.05， P<0.01）. The differences in whole-blood viscosity （low， medium， and high rate of shear） were all significantly decreased （P<0.01）. The results of HE staining and transmission electron microscopy showed that the morphology， structure， and mitochondria of cardiomyocytes were improved. The content of 12-HETE and 15-HETE in serum was reduced to different degrees in low-， medium-， and high-dose groups of Xuefu Zhuyutang （P<0.05， P<0.01）. The content of Fe²⁺， LPO， and ROS was significantly reduced in the medium- and high-dose groups of Xuefu Zhuyutang （P<0.05， P<0.01）， and the content of GSH and T-GSH/GSSG was significantly increased （P<0.05， P<0.01）. The protein and mRNA expressions of GPX4 and FTH1 were significantly increased to varying degrees in the medium- and high-dose groups of Xuefu Zhuyutang （P<0.05， P<0.01）， and ACSL4 and LPCAT3 were decreased to different degrees in the low-， medium-， and high-dose groups of Xuefu Zhuyutang （P<0.05， P<0.01）. ConclusionXuefu Zhuyutang can regulate iron metabolism and anti-lipid oxidation reaction to mediate ferroptosis through the ACSL4 signalling pathway， thus exerting a protective effect on rats with coronary heart disease with blood stasis syndrome.

Objective To explore the effect of interest induction combined with integrated healthcare nursing on improvements of mental health and prognosis in children with lobar pneumonia.Methods A total of 126 children diagnosed as lobar pneumonia in the Hebei Children's Hospital from October 2023 to October 2024 were selected as research objects and randomly divided into study group(n=63)and control group(n=63).The control group received conventional nursing interven-tions,while the study group received the interest induction combined with integrated healthcare nursing model.The time for improvement of clinical symptoms,psychological scores,therapeutic compliance,and the occurrence of complications were compared between the two groups.Results The resolution time for fever,obvious alleviation time for cough,relief time for shortness of breath,and disappear-ance time for moist rales in the study group were significantly shorter than those in the control group(P＜0.05).After the intervention,the scores of the Multidimensional Anxiety Scale for Children(MASC-C)and the Child Behavior Checklist(CBCL)in both groups were significantly lower than those before the intervention,and the scores in the study group were significantly lower than those in the control group(P＜0.05).The compliance scores of the study group in terms of taking medication on time,functional exercise,dietary adjustment,and self-monitoring dimensions were all significantly higher than those of the control group(P＜0.05).In the study group,there was 1 case of atelecta-sis and 1 case of pneumothorax,with a total complication rate of 3.17％(2/63);there was 1 case of pleural effusion,1 case of atelectasis,and 2 cases of pneumothorax in the control group,with a total complication rate of 6.35％(4/63).There was no significant difference in the total complica-tion rate between the two groups(x2=0.700,P＞0.05).Conclusion The interest induction combined with integrated healthcare nursing model can improve therapeutic compliance,shorten the time for improvement of clinical symptoms,and enhance the mental health of children.

Objective To systematically evaluate the safety and efficacy of Kangfuxin liquid combined with adenosine monophosphate in the treatment of paediatric herpetic stomatitis.Methods Randomised controlled trials(RCTs)of Kangfuxin liquid combined with adenosine monophosphate for the treatment of paediatric herpetic stomatitis were searched in various databases,and Meta-analysis was performed using RevMan 5.4 software.Results A total of 12 RCTs with a sample size of 1,094 cases were included.Meta-analysis showed that the combination of Kangfuxin liquid with adenosine monophosphate significantly increased[RR=1.21,95%CI(1.16,1.28),P<0.000 01]the overall clinical efficacy rate of paediatric herpetic stomatitis.Compared with the conventional antiviral treatment group with adenosine monophosphate,the incidence of adverse events was lower in the Kangfuxin liquid group[RR=0.26,95%CI(0.14,0.51),P<0.000 01].In addition,the Kangfuxin liquid group could effectively shorten the time for herpes disappearance(skin lesion healing),pain disappearance,fever reduction,salivation disappearance and recovery of diet(P<0.05),and had advantages in promoting the recovery of lymphocytes(CD3+,CD4+,CD8+,and CD4+/CD8+),serological levels(CRP,TNF-α,WBC,IL-10,VEGF,EGF,and IL-6)(P<0.05).Conclusion Kangfuxin liquid combined with adenosine monophosphate has the better efficacy and safety in the treatment of paediatric herpetic stomatitis,and has advantages in shortening the symptomatic recovery time and improving the indicators of lymphocyte and serological levels in paediatric herpetic stomatitis.

Huntington's disease (HD) is an inherited neurodegenerative disorder caused by the abnormal expansion of CAG trinucleotide repeats in the Huntingtin gene (HTT) located on chromosome 4. It is transmitted in an autosomal dominant manner and is characterized by motor dysfunction, cognitive decline, and emotional disturbances. To date, there are no curative treatments for HD have been developed; current therapeutic approaches focus on symptom relief and comprehensive care through coordinated pharmacological and nonpharmacological methods to manage the diverse phenotypes of the disease. International clinical guidelines for the treatment of HD are continually being revised in an effort to enhance care within a multidisciplinary framework. Additionally, innovative gene and cell therapy strategies are being actively researched and developed to address the complexities of the disorder and improve treatment outcomes. This review endeavours to elucidate the current and emerging gene and cell therapy strategies for HD, offering a detailed insight into the complexities of the disorder and looking forward to future treatment paradigms. Considering the complexity of the underlying mechanisms driving HD, a synergistic treatment strategy that integrates various factors-such as distinct cell types, epigenetic patterns, genetic components, and methods to improve the cerebral microenvironment-may significantly enhance therapeutic outcomes. In the future, we eagerly anticipate ongoing innovations in interdisciplinary research that will bring profound advancements and refinements in the treatment of HD.

Objective:The aim of this study was to analyze the registration status of osteoporosis drug clinical trials in China, providing a reference for the research and development of therapeutic drugs for osteoporosis.Methods:Using the Drug Clinical Trial Registration and Information Publication Platform on the website of the State Drug Administration as the search platform, we retrieved the information on the public announcement of drug clinical trials with osteoporosis as an indication, and the search period was limited from 2013 to February 2025.Researchers extracted the key information and performed statistics.Results:A total of 182 registered osteoporosis drug clinical trial projects were collected.The main target indications were predominantly osteoporosis in postmenopausal women, and there were relatively few trials targeting the elderly subjects.56.0%(102/182)of the registered trials were bioequivalence studies, and 21.4%(39/182)were phase I clinical studies.Conclusions:The number of registered trials and the research and development process of domestic osteoporosis drug clinical trials in China have shown a stable trend in general, and the types of trials are mainly concentrated in bioequivalence studies and early clinical studies.In order to further meet the medication needs of domestic patients, China still needs to increase the research and development efforts of innovative osteoporosis drugs.

Objective:To investigate the role of the Brock, Mayo, and PKUPH combined model in risk stratification of solitary pulmonary nodules (SPNs) in health check-up population.Methods:An ambispective cohort study was conducted on 668 eligible SPNs cases from the health management center in Chongqing General Hospital from June 2018 to June 2019. The exposure condition was prospectively followed or historically retrospected, and the clinical outcomes were prospectively followed. SPNs were classified into benign and malignant groups. Descriptive statistics and univariate analysis were performed to assess the differences in risk characteristics between two groups. Receiver operating characteristic (ROC) curve, clinical decision curve, and Hosmer-Lemeshow goodness-of-fit test were used to evaluate and compare the predictive performance, clinical utility, and calibration of the combined model versus individual Brock, Mayo, and PKUPH models.Results:Among the 668 SPNs cases, 82 (12.28%) were diagnosed as malignant. Age, sex, smoking history, extrapulmonary tumor history, diameter, upper lobe, clear border and spicule sign in the malignant group were significantly different from those in the benign group (all P<0.05). The combined model demonstrated superior predictive performance, clinical utility, and calibration compared to the best-performing individual Brock model [Area under the curve (AUC): 0.88 (95% CI: 0.84-0.92) vs 0.86 (95% CI: 0.82-0.91)]. Besides, multi-grade risk stratification enabled by the combined model was better than binary classification, with the malignant rate of the four risk levels were 0.60%, 4.62%, 14.58% and 56.07%, respectively. Conclusion:The combined model addresses the limitations of individual models in SPNs risk stratification for health examination populations, improving predictive performance, clinical utility, and calibration, while proposing a superior multi-grade risk stratification system.
