Objective:To assess the efficacy and safety of Gongxuening Capsules in reducing post-abortion bleeding following artificial abortion.Methods:A multicenter, randomized, double-blind study was conducted. From May 31, 2022 to March 31, 2023, 484 women who underwent vacuum aspiration abortion for early intrauterine pregnancy were enrolled in 11 centers and randomly assigned to control group and the study group at a 1∶1 ratio using a center-block randomization method. Control group were administered a placebo of Gongxuening Capsules for 9 d, while the study group received the actual Gongxuening Capsules for the same duration. The outcomes measured included vaginal bleeding volume, duration of vaginal bleeding, endometrial thickness, time to menstrual recovery, and complications.Results:1) A total of 484 subjects were enrolled, and 472 completed the study. Totally 450 subjects were included in the efficacy analysis set, with 224 in control group and 226 in the study group; 468 subjects were included in the safety analysis set, with 236 in control group and 232 in the study group. The baseline characteristics of the two groups were comparable (all P>0.05). 2) The vaginal bleeding volume was lower in the study group [(13.30±12.14) mL] than in control group [(19.00±17.67) mL, P<0.001]. The proportion of subjects in the study group with bleeding days less than 4 d [29.65% (67/226)] was higher than that in control group [19.20% (43/224), P=0.010]. 3) No significant differences were observed between the two groups in terms of time to menstrual recovery and endometrial thickness (all P>0.05). 4) In the study group, 3 subjects experienced non-therapeutic-related complications, while 11 subjects in control group. The incidence of complications was lower in the study group [1.29% (3/232)] than in control group [4.66% (11/236), P=0.033]. Conclusion:The administration of Gongxuening Capsules to women following artificial abortion significantly reduced vaginal bleeding volume and was associated with good safety, with the treatment being well-tolerated by the subjects.

Objective To analyze the types and distribution of microbiome in intestinal and lung tissues of children with asthma, and to explore the correlation between microbiota changes and asthma. Methods From 2021 to 2023, a total of 28,939 children with asthma who visited Ezhou Central Hospital, Maternal and Child Health Hospital or Ezhou Egang Hospital were selected as the study subjects, and 2,000 healthy children who underwent outpatient physical examinations at these three hospitals during the same period were selected as the control group. The distribution and characteristics of intestinal and pulmonary microbiome in the two groups were analyzed by 16SrDNA sequencing. Logistic regression analysis model was used to analyze the correlation between microbiota distribution and asthma occurrence. Results In the intestinal tissues of children with asthma compared to healthy children, the abundance of Bacteroidetes at the phylum level decreased, while the abundance of Firmicutes and Proteobacteria increased significantly (P<0.05), and the abundance of Prevotalle and Clostridium at the genus level increased significantly. In lung tissues of asthmatic children compared to health children, the abundance of Firmicutes at the phylum level decreased while the abundance of Proteobacteria increased significantly (P<0.05), and the abundance of Neisseria, Prevotella and Actinomyces at the genus level increased significantly. Binary logistic regression results showed that the abundances of Lactobacillus (OR=0.842, 95% CI: 0.533-0.947), Bacteroides fragilis (OR=0.649, 95%CI: 0.377-0.890), Bifidobacterium (OR=0.901, 95% CI: 0.633-0.994), and Parabacteroides distasonis (OR=0.547, 95% CI: 0.192-0.708) in the intestinal tissues were all protective factors for the asthma in children. In the lung tissue, the abundance of Neisseria (OR=2.140, 95% CI: 1.749-3.305) was a risk factor for the asthma in children, and Prevotella (OR=0.691, 95% CI: 0.491-0.926) was a protective factor for the asthma in children (P<0.05). Conclusion The dysbiosis of intestinal and pulmonary microbiome is closely related to the occurrence of asthma in children, and the detection of microbiota is of great significance for the diagnosis of childhood asthma.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To analyze the hotspots and frontiers of researches related to exercise intervention for spinal curvature abnor-malities in children and adolescents. Methods Articles related to exercise intervention for spinal curvature abnormalities in children and adolescents were re-trieved from CNKI and Web of Science Core Collection,from January,2014 to December,2023.The literatures were analyzed wtih CiteSapce 6.2.R3 in terms of disciplines,countries,institutes and keywords. Results A total of 233 articles were retrived,including 71 articles in Chinese and 162 articles in English.The annual pub-lication volume was on the rise.China was the country with the highest number of publications.South Korea was seen a sudden increase in recent literature.For Chinese,the institutions with the largest number of publication were the Department of Health and Exercise Science in Tianjin University of Sport and Luoyang Orthopedic-Traumatological Hospital of Henan Province(Henan Provincial Orthopedic Hospital).While the institutions with the largest number of publication in English were Marmara University and Hong Kong Polytechnic University.The English literatures covered a wide range of disciplines,including clinical medicine,sports medicine,neurolo-gy and psychology.Common high-frequency keywords in both Chinese and English literatures were idiopathic scoliosis,Cobb's angle and Schroth exercise.The latest bursting words included physical health in Chinese,and health-related quality of life and respiratory muscle strength in English. Conclusion The research popularity related to exercise intervention for spinal curvature abnormality in children and ado-lescents is generally on the rise.The research hotspots focus on four main areas:disease,quality of life,research advances and clinical treatment.More attention should be paid to the effect and dosage of exercise intervention on the respiratory function,as well as the effect of Chinese medicine exercise therapy on pediatric patients with abnormal spinal curvature diseases.Future work should focus on constructing an evidence-based Chinese/West-ern medicine exercise prevention and treatment system in the context of China's national conditions,advancing high-quality randomized controlled trials,strengthening interdisciplinary and international collaborations,and fo-cusing on the development and evaluation of personalized exercise intervention programs.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in healthcare facilities in major regions of China in 2023.Methods Clinical isolates collected from 73 hospitals across China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2023 Clinical & Laboratory Standards Institute (CLSI) breakpoints.Results A total of 445199 clinical isolates were collected in 2023,of which 29.0％ were gram-positive and 71.0％ were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species (excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi) (MRSA,MRSE and MRCNS) was 29.6％,81.9％ and 78.5％,respectively.Methicillin-resistant strains showed significantly higher resistance rates to most antimicrobial agents than methicillin-susceptible strains (MSSA,MSSE and MSCNS).Overall,92.9％ of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 91.4％ of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis had significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 93.1％ in the isolates from children and and 95.9％ in the isolates from adults.The resistance rate to carbapenems was lower than 15.0％ for most Enterobacterales species except for Klebsiella,22.5％ and 23.6％ of which were resistant to imipenem and meropenem,respectively .Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.6％ to 10.0％.The resistance rate to imipenem and meropenem was 21.9％ and 17.4％ for Pseudomonas aeruginosa,respectively,and 67.5％ and 68.1％ for Acinetobacter baumannii,respectively.Conclusions Increasing resistance to the commonly used antimicrobial agents is still observed in clinical bacterial isolates.However,the prevalence of important crabapenem-resistant organisms such as crabapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a slightly decreasing trend.This finding suggests that strengthening bacterial resistance surveillance and multidisciplinary linkage are important for preventing the occurrence and development of bacterial resistance.

Objective:To survey the awareness status of risk factors for gastric cancer and related factors among residents in Shijiazhuang city.Methods:From October to November 2020, residents aged>18 years were selected through convenience sampling from Xinhua District and Yuhua District in Shijiazhuang for a face-to-face questionnaire survey. The demographic characteristics and awareness levels of risk factors for gastric cancer among 1 490 subjects were analyzed. The multivariate linear regression model was applied to analyze the related factors.Results:There were 522 male participants (35.0%) and 968 female participants (65.0%). The mean knowledge score of risk factors of gastric carcinoma in the respondents was 5.0 (1.0, 11.0). There were 57.0% (849/1 490) of the participants who had a low knowledge level about risk factors of gastric cancer. The more highly recognized risk factors were irregular diet (47.4%, 706/1 490), consumption of pickled foods (45.2%, 674/1 490), consumption of smoked foods (45.0%, 671/1 490); the less-recognized risk factors included physical inactivity (14.8%, 221/1 490), male sex (17.3%, 258/1 490) and older age (19.5%, 291/1 490). Only 26.8% (400/1490) of the participants regarded H. pylori infection as a risk factor of gastric cancer. Univariate analysis showed that educational level ( Z=39.34), marital status ( Z=53.31), monthly income ( Z=11.82), family member or friend ever having stomach problem ( H=-2.98), and family history of gastric cancer ( H=-2.34) were significantly associated with the knowledge score of risk factors for gastric cancer ( P<0.05). Multivariate analysis showed that compared to participants with educational levels of primary school or below, those with educational level of junior high school ( β=0.27, P<0.001), high school ( β=0.23, P<0.001), or college ( β=0.16, P<0.001) had a higher levels of knowledge of risk factors for gastric cancer; compared to unmarried participants, awareness of risk factors was significantly better in those who were married ( β=0.16, P<0.001), divorced ( β=0.05, P=0.039), or widowed ( β=0.06, P=0.027); compared to participants with monthly income<3 000 yuan, the subjects with monthly income from 5 000 to 10 000 yuan ( β=0.07, P=0.020) had a higher knowledge score; compared to participants with no family history of gastric cancer, subjects with family history had higher knowledge level of risk factors for gastric cancer ( β=0.06, P=0.029). Conclusion:The knowledge levels of risk factors for gastric cancer are generally low among residents in Shijiazhuang city. Educational initiatives are required to improve the awareness of risk factors for gastric cancer, and interventions need to be implemented concurrently to change unhealthy behaviors among residents in Shijiazhuang city.

Objective:To determine the effect of short-term high protein and low carbohydrate diet interventions on weight-related metabolic indexes in obese patients with hypertension.Methods:A retrospective study was conducted on 200 obese patients with hypertension who underwent physical examination and weight management in Shenzhen People′s Hospital from May 2015 to December 2019. Among them, 100 patients were given routine diet education (control group), and 100 patients were given high protein and low carbohydrate diet interventions (experimental group). After eight weeks, changes in body weight, body mass index, blood pressure, fasting blood glucose, blood lipid, and medical expenses were compared. T-test and Wilcoxon rank sum test were used to compare the differences between the two groups before and after the interventions. When P<0.05, it was considered significantly different. Results:After the intervention, body weight, body mass index, systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, triglycerides, and medical expenses of the experimental group decreased [79.0 (74.0, 85.0) vs 70.0 (66.0, 72.0) kg; 28.5 (26.8, 29.5) vs 26.1 (25.4, 27.7) kg/m 2; 168.0 (162.0, 178.0) vs 160.0 (154.0, 166.0) mmHg(1 mmHg=0.133 kPa); 101.0 (98.0, 108.0) vs 97.0 (90.5, 98.0) mmHg; 5.25 (4.80, 5.52) vs 4.95 (4.70, 5.20) mmol/L; 5.80 (5.27, 6.40) vs 5.40 (5.00, 5.80) mmol/L; 1.25 (0.90, 1.50) vs 1.10 (0.90, 1.20) mmol/L;(669.6±21.6) vs (646.4±21.3) CNY, respectively] (all P<0.05). The body weight of the control group decreased [78.0(73.3, 83.0) vs 79.5(74.5, 85.0) kg] ( P<0.05). The control group′s body mass index, systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, triglycerides, and medical expenses had no significant changes (all P>0.05). Conclusion:Short-term, high protein, low carbohydrate diet intervention can effectively reduce weight, hypertension, fasting blood glucose, total cholesterol, triglycerides, and medical expenses in obese patients with hypertension.

Objective:To retrospectively analyze the bone marrow smears of neuroblastoma and rhabdomyosarcoma in children and summarize the morphological characteristics of the two types of tumors invading the bone marrow to provide reference for the identification and differential diagnosis.Method:A total of 908 bone marrow specimens were collected from the outpatient and inpatient children who were diagnosed as Neuroblastoma and Rhabdomyosarcoma by pathological tissue or lymph node biopsy in Sun Yat-sen University Cancer Center from January 2013 to July 2020. Of which, 231 cases of tumor bone marrow metastasis were detected. Bone marrow smears were observed and analyzed, classified and summarized according to the morphological characteristics of tumor cells.Result:A total of 231 cases of bone marrow metastases were detected, including two types of tumors, 217 cases Neuroblastoma, with an invasion rate of 34.23%; 14 cases Rhabdomyosarcoma, with an invasion rate of 5.11%. The tumor cells of neuroblastoma were arranged in a pseudo-chrysanthemum or wall-like arrangement and most of them were surrounded by nerve fibers. According to cell size, they could be divided into large cell type and small cell type. Rhabdomyosarcoma cells were mainly medium in size, with vacuoles in the nucleus, and double, triple and multinucleated cells can be seen. The cytoplasm was gauze-like, with bead-like vacuoles at the edges. According to the morphological characteristics of neuroblastoma and rhabdomyosarcoma, they can be differentiated from acute leukemia.Conclusion:Among two malignant solid tumors in children, Neuroblastoma had a higher bone marrow invasion rate, while Rhabdomyosarcoma had a lower bone marrow invasion rate. Rhabdomyosarcoma can be initially divided into embryonal type and acinar type according to whether tumor cells were fused or not.
