Objective To explore the incidence rate and related factors of dyslipidemia in children with simple obesity and overweight. Methods From October 2018 to December 2023, 254 children with simple obesity and overweight who received physical examination in the pediatric outpatient department of Beijing Jishuitan Hospital were selected as the observation group, and 46 healthy children during the same period were included in the control group. According to whether dyslipidemia occurred, children with simple obesity and overweight were classified into the dyslipidemia group (n=97) and the normal blood lipid group (n=157). Logistic regression analysis was used to analyze the related factors affecting dyslipidemia in children with simple obesity and overweight. Results The concentrations of total cholesterol (TC) and triglyceride (TG) of children in the observation group were significantly higher than those in the control group (P<0.05), while the level of high-density lipoprotein cholesterol (HDL-C) showed the opposite trend and was significantly lower than that in the control group (P<0.05). After logistic regression analysis, it was found that body mass index (BMI), fasting insulin level, alanine aminotransferase (ALT) activity, uric acid level, and daily sedentary time were related factors influencing dyslipidemia in children with simple obesity and overweight (P<0.05). Conclusion The incidence rate of dyslipidemia is high in children with simple obesity and overweight. BMI, fasting insulin level, ALT, uric acid level, and daily sedentary time are related factors of dyslipidemia in children with simple obesity and overweight.

ObjectiveTo analyze the epidemiological and clinical characteristics of the 21 confirmed monkeypox cases in a district of Chengdu City, and to provide scientific guidance for the prevention and control of subsequent monkeypox epidemics. MethodsData of confirmed monkeypox cases residing in this district were collected from the Disease Control and Prevention Information System of China. A retrospective descriptive epidemiological analysis was used to analyze the demographic, distributional and behavioral characteristics of the cases. ResultsThe first confirmed case of monkeypox was reported on July 5, 2023. Up to April 30, 2025, a total of 21 confirmed cases of monkeypox have been reported. All cases were male, with a mean age of (30.9±6.2) years. The highest proportion of cases(47.62%) was in the 30‒40 years age group. The majority were men who have sex with men (MSM) population (90.48%, 19/21). The results showed that 19.05% of cases were co-infected with HIV, and 19.05% had a history of syphilis infection. Within 21 days prior to symptom onset, 19 cases (90.48%) self-reported engaging in male-to-male sexual contact, among whom 10 cases (52.63%) reported having taken protective measures, while 9 cases (47.37%) did not take safety precautions. Thirteen cases (61.90%) had no travel history to areas with reported monkeypox cases during the 21 days before symptom onset. The predominant manifestation was exanthem (100%, 21/21), followed by fever (57.14%, 12/21) and lymphadenectasis (47.62%, 10/21). Among febrile cases, 50.00% (6/12) had low-grade fever (37.3‒38.0 ℃). All cases were identified through active medical consultation. The median interval from symptom onset to the first medical visit was 3 (2, 6) days, with a maximum interval of 14 days. The median interval from symptom onset to laboratory confirmation was 7 (5, 9) days. Six cases (28.57%) had two or more visits to the hospital, with bacterial infection being the primary initial diagnosis. ConclusionMonkeypox prevention and control efforts in a district of Chengdu City should prioritize MSM population and young and middle-aged adults aged 30 to <40 years. It is recommended to establish an integrated monkeypox epidemic prevention and control network by leveraging existing HIV/AIDS prevention and control network. Concurrently, accelerating the deployment of the national intelligent infectious disease monitoring and early warning front-end software will strengthen early detection capabilities and be beneficial for the overall effectiveness of epidemic prevention and control efforts.

Huangqintang， with its accurate efficacy， is a classic formula specialized in treating dysentery recommended and promoted by medical experts from successive generations， and it was included in the Catalogue of Ancient Classic Prescriptions （the Second Batch， Han Chinese medicine prescriptions） published by the National Administration of Traditional Chinses Medicine （TCM） in 2023. The method of bibliometrics was applied in this study to conduct textual research on the classic formula Huangqintang and provide a literature reference for the development of modern preparations of Huangqintang. A total of 2 026 pieces of ancient literature were searched with "Huangqintang" as the key word， and 23 pieces of effective data were selected， involving 15 ancient TCM books. The historic evolution， composition， dosage， origin， processing methods， preparation and decocting methods， efficiency， and application of Huangqintang were carefully reviewed. The results showed that Huangqintang was first recorded in the Treatise on Febrile Diseases written by ZHANG Zhongjing. It has the effect of clearing heat， stopping dysentery， regulating the middle， and downbearing counterflow and has become one of the classic formulas widely used in clinical practice. Because of its accurate efficacy， medical experts from later generations have modified it from its original composition. Though many prescriptions have different names， it is the manifestation of physicians' inheritance and development of the thought of ZHANG Zhongjing. Ancient literature showed this prescription had wide indications yet centered on digestive system diseases such as dysentery and abdominal pain. Modern applications of Huangqintang involve digestive， respiratory， ophthalmology and otolaryngology， gynecological， skin， musculoskeletal system， and connective tissue， and this prescription has great potential in treating ulcerative colitis， diarrhea， acute enteritis， and damp-heat dysentery. Through a systematic textual excavation and review of the ancient literature about Huangqintang， the paper has confirmed its key information， so as to provide a scientific basis for the clinical application and new drug development of classic formulas.

OBJECTIVE: To block the transmission of Cranio-facial-nasal syndrome (CFNS) caused by a large deletion of the EFNB1 gene through preimplantation genetic testing for monogenic disorders (PGT-M). METHODS: A patient with craniofacial deformities and his parents who had visited Shiyan People's Hospital in June 2020 were selected as the study subjects. The child underwent whole exome sequencing (WES) and qPCR validation. After genetic counseling, PGT-M was chosen for the reproductive blockage. This study was approved by the Ethics Committee of the Hospital (Ethics No.: sysrmyy-087). RESULTS: The child was diagnosed with CFNS due to a heterozygous deletion of exons 1-5 of the EFNB1 gene through WES and qPCR, which showed a X-linked dominant inheritance. The mother underwent ovarian stimulation with a modified PPOS protocol, which has yielded 11 oocytes. After ICSI fertilization, 4 blastocysts were formed, and MALBAC whole genome amplification was performed on the trophoblast biopsy cells, and SNP haplotypes of the family members and embryos were analyzed to indirectly determine the presence of maternal pathogenic haplotypes. Chromosomal copy number variation analysis was conducted through next-generation sequencing to screen for euploid embryos, resulting in the identification of two euploid embryos that did not carry the mutation of the EFNB1 gene. The first transfer was unsuccessful, but after adjusting the transfer timing through endometrial receptivity assessment (ERA), clinical pregnancy was achieved. Prenatal diagnosis at 19 weeks excluded the EFNB1 gene exons 1-5 deletion in the fetus. A healthy girl was delivered by Cesarean section at 38⁺⁶ weeks, and Q-PCR confirmed she has no aforementioned EFNB1 gene deletion. CONCLUSION This study has successfully blocked the transmission of CFNS caused by a large deletion of the EFNB1 gene (exons 1-5) using a PGT-M strategy, which may provide reference for the intervention of similar genomic variations that cannot be directly detected.

Objective To explore changes of blood cell counts and hepatic and splenic fibrosis rates in rat models of liver cirrhosis and portal hypertension after partial splenic artery embolization(PSE).Methods Fifteen rat models of liver cirrhosis and portal hypertension were successfully established.Red blood cell(RBC),white blood cell(WBC)and platelet(PLT)counts were measured.Splenic artery angiography and PSE were performed in 10 rats(PSE group),while only splenic artery angiography was performed in the rest 5 rats(control group).1 week after interventions,RBC,WBC and PLT counts were remeasured,and then the rats were euthanized to obtain liver and spleen specimens for pathological examination and evaluation of fibrosis rate.The changes of blood cell count within 1 week and the hepatic and splenic fibrosis rates 1 week after intervention were compared between groups.Results Rats in both groups exhibited good general condition within 1 week after intervention.One week after intervention,RBC,WBC and PLT counts in PSE group were all significantly higher than those before intervention(all P＜0.05),and the increasing rate of RBC,WBC and PLT counts in PSE group were larger than those in control group(all P＜0.05).WBC and PLT counts in PSE group 1 week after intervention were all higher than those in control group(both P＜0.05),but no significant difference of RBC count was observed between groups(P＞0.05).One week after intervention,hepatic fibrosis rate was higher,while splenic fibrosis rate was lower in PSE group than that in control group(both P＜0.05).Conclusion PSE might be used to improve decrease of blood cell count caused by hypersplenism in rat with liver cirrhosis and portal hypertension,hence reverse or slow down progression of splenic fibrosis.

Objective To investigate the effect and mechanisms of celecoxib on right heart function in mice with acute high-altitude hypoxia exposure.Methods Male C57BL/6J mice(7 weeks old)were housed in a hypobaric chamber simulating an altitude of 5 800 m for 2 d to establish an animal model of acute hypobaric hypoxia.①Eighteen mice were randomly assigned to plain+saline(P+S),high-altitude hypoxia exposure+saline(H+S),and high-altitude hypoxia exposure+celecoxib(H+Cel).Body weight and routine blood indicators were measured,and cardiac ultrasound examination were performed for heart rate(HR),pulmonary artery acceleration time to ejection time ratio(AT/ET),tricuspid annular plane systolic excursion(TAPSE),tricuspid annular systolic velocity(S'),and left ventricular ejection fraction(LVEF)and fractional shortening(FS).Targeted metabolomic profiling was applied to detect the cardiac arachidonic acid(AA)metabolite levels.The contents of 12,13-dihydroxy-9Z-octadecenoic acid(12,13-diHOME)in the heart,liver,brown adipose tissue,and plasma were quantified by ELISA.② Eighteen mice were randomly assigned into plain+saline(P+S),high-altitude hypoxia exposure+saline(H+S)and high-altitude hypoxia exposure+12,13-diHOME(H+di)groups.Body weight,routine blood tests,and echocardiography were performed as above.③ Thirty-two mice were randomly divided into high-altitude hypoxia exposure+saline(H+S),high-altitude hypoxia exposure+celecoxib(H+Cel),high-altitude hypoxia exposure+soluble epoxide hydrolase inhibitor(sEHI)(H+sEHI),and high-altitude hypoxia exposure+sEHI+celecoxib(H+sEHI+Cel)groups.Body weight,routine blood tests,and echocardiography were performed as above.Cardiac and plasma contents of 12,13-diHOME and epoxyeicosatrienoic acids(EETs)were measured by ELISA.Results ① Compared to the P+S group,the H+S group exhibited significantly reduction of cardiac 12,13-diHOME level(P<0.001),increased counts of white blood cells(WBC)and neutrophils(P<0.01)and decreased TAPSE,S'and AT/ET both at resting state and under stress(P<0.01,P<0.001).Compared to the H+S group,the H+Cel group exhibited significantly increase of cardiac 12,13-diHOME level(P<0.05),reduced WBC and lymphocyte counts(P<0.01,P<0.05)and improved TAPSE and S'levels at resting state and under stress(P<0.01,P<0.001).② Compared to the H+S group,the H+di group demonstrated significantly improvement of TAPSE at basal and under stress(P<0.001)and a trend towards improved TAPSE at resting state(P=0.0532),but no obvious differences was observed in WBC and neutrophil counts between the H+di group and the H+S group.③ Compared to the H+Cel group,both the H+sEHI and H+sEHI+Cel groups exhibited significantly reduction of cardiac 12,13-diHOME level(P<0.01,P<0.05)though no statistical changes in cardiac function indicators.Compared to the H+S group,WBC counts and lymphocyte were decreased,and serum EETs level was incrased in the H+Cel group,H+sEHI group and H+sEHI+Cel group(P<0.01,P<0.001).Conclusion Celecoxib can elevate cardiac level of 12,13-diHOME and improves right heart function in mice after acute high-altitude hypoxia exposure through the CYP450-sEH metabolic pathway.

Biofilm formation is one of the key reasons that bacterial infections are difficult to treat.So it is of great significance to develop effective strategies to resist bacterial biofilms.Although antibiotics are important clinical tools for the treatment of bacterial infections,their therapeutic efficacy is often unsatisfactory when targeting bacterial biofilm-associated diseases.In this study,exopolysaccharides(EPS)from Escherichia coli(E.coli)were extracted and purified.It was demonstrated that the obtained E.coli EPS had the ability to inhibit methicillin-resistant Staphylococcus aureus(MRSA)biofilm formation and disperse a mature biofilm.To improve the anti-biofilm effect of vancomycin(VAN),E.coli EPS was used in combination with VAN.The combination increased the inhibition rate of MRSA biofilm and increased the dispersion rate of mature biofilm from 10%to 80%.When combined with E.coli EPS,the number of bacterial colonies within the MRSA biofilm remarkably decreased by 88%,resulting in a significant improvement over the use of VAN alone at an equivalent concentration.Meanwhile,E.coli EPS could down-regulate the expression of MRSA biofilm-related genes.E.coli EPS showed good anti-biofilm effect,and E.coli EPS/VAN combination could provided a potential strategy for treatment of MRSA biofilm infections.

Objective:To analyze the characteristics of cardiovascular and cerebrovascular diseases in patients with primary aldosteronism (PA) and compare them with age-, sex-, and blood pressure-matched patients with essential hypertension (EH).Methods:This cross-sectional study was conducted at the West China Hospital of Sichuan University. Patients with PA and EH between December 2018 and December 2021 were included. Demographic characteristics, stroke events, coronary artery diseases, peripheral vascular diseases, and cardiac structure and function indicators were analyzed. Propensity score matching (PSM) was used to balance non-study data. The t-test, chi-square test, and Wilcoxon signed-rank test were used for data comparison. The cardiovascular and cerebrovascular damage in the patients with unilateral and bilateral PA were also compared. Results:A total of 336 and 369 patients with PA and EH, respectively, were enrolled in this study. One hundred and ninety-eight patients from each group were included after PSM; no significant differences were found in terms of age, gender, and blood pressure. The prevalence of stroke in the PA group was considerably higher than that in the EH group [12.6% (25/198) vs. 5.6% (11/198), P=0.014], due to the significantly greater risk of ischemic stroke [10.0% (20/198) vs. 4.5% (9/198), P=0.029]. The prevalence of hemorrhagic stroke, coronary artery disease, peripheral arterial stenosis, aorta atherosclerosis, and aneurysm in the PA group were also higher than those in the EH group, but there was no statistical significance (all P>0.05). More patients with PA had concurrent left ventricular hypertrophy [22.2% (44/198) vs. 9.1% (18/198)], left atrial enlargement [40.4% (80/198) vs. 30.3% (60/198)], ventricular septal thickening [50.0% (99/198) vs. 36.9% (73/198)], and aortic widening [21.7% (43/198) vs. 13.1% (26/198)] than those with EH (all P<0.05). Compared with the bilateral PA group, the unilateral PA group had higher prevalence of left ventricular hypertrophy [28.3% (51/180) vs. 13.4% (11/82), P=0.013]. Conclusions:Compared with well-matched patients with EH, patients with PA have significantly higher risks of cardiovascular and cerebrovascular diseases, which are mainly manifested in increased prevalence of stroke and severe damage to the cardiac structure. Patients with unilateral PA may suffer more severe cardiac damage than those with bilateral PA.

Objective To construct a nursing follow-up checklist for patients undergoing autologous hematopoietic stem cell transplantation,providing a basis for postoperative follow-up care.Methods Using evidence-based methods,the literature from major guide websites and databases using Chinese and English search terms was retrieved,and their quality was evaluated.The relevant items were extracted,and a first draft was formed.15 experts were selected in relevant fields from 14 tertiary hospitals in 13 provinces,cities,and autonomous regions across the country for Delphi inquiry.The nursing follow-up checklist was revised again based on expert opinions and clinical practice.The nursing follow-up checklist was initially applied and then revised again to form the final draft.Results 15 experts include 12 undergraduate and 3 master's degree holders.The positivity coefficients of the 2 rounds of inquiry were 100％;the authority coefficients of the experts were 0.815;the Kendall coefficients were 0.119 and 0.144,respectively;the differences were statistically significant(P＜0.001).The final nursing follow-up checklist was formed,which includes 6 primary indicators,including physiological status,psychological status,social and family support,living conditions,disease knowledge,and laboratory tests.19 patients(95％)found the follow-up content to be comprehensive.The follow-up nurses's satisfaction rate exceeded 85％.There were 27 secondary indicators and 61 tertiary indicators,with coefficients of variation of all indicators less than 0.25.Conclusion The nursing follow-up checklist is scientific,reliable,and practical,which can provide a basis for clinical nursing staff to follow up and comprehensively manage patients after autologous hematopoietic stem cell transplantation.

ObjectiveTo construct an intelligent model for literature screening， retrieval， and data extraction with a systematic review of coronary heart disease syndromes as an example， so as to improve the efficiency of evidence-based Chinese medicine research. MethodsBased on China National Knowledge Infrastructure （CNKI）， VIP and Wanfang Data Resource System， the articles related to coronary heart disease syndrome research published from January 1， 2000 to December 31， 2023 were retrieved. Automated tools were used to batch retrieve paper metadata. Using text similarity algorithms， papers were merged， deduplicated， and subjected to preliminary screening based on titles and abstracts. Further screening was performed using object detection and image processing technologies on the full texts and statistical tables. Natural language processing （NLP） techniques and pre-trained models were applied to extract information. ResultsThe initial search retrieved 56 255 coronary heart disease syndrome-related articles. By artificial intelligence-assisted preliminary and secondary screening， the manual verification scope was narrowed to 1075 articles. Ultimately， 646 coronary heart disease syndrome related studies were included manually. With accuracy verification showing over 90% consistency in semantic recognition and element decomposition processes， we achieved data extraction and standardization processing for both basic literature information and 38 syndrome element statistics. ConclusionBy incorporating natural language processing， pre-trained models， artificial intelligence image processing and other technologies， this study enabled efficient retrieval， screening and standardized data extraction of Chinese medicine research literature.
