Adolescents in Northeast, East, and Southwest of China had the highest rate of cycling violation (44%), of which junior high school students had the highest rate of violation [42% (95%CI: 36%‒49%)]. As for the walking violation rate, male students [29% (95%CI: 21%‒37%)] was higher than that of female students [22% (95%CI: 15%‒30%)]. Adolescents in North of China had the highest rate of walking violation [54% (95%CI: 30%‒76%)], of which vocational school students accounted for 38% (95%CI:21%‒56%) of the total violation. In terms of the detection rate of unsafe swimming, male students [18% (95%CI: 14%‒24%)] was higher than that of female students [8% (95%CI: 6%‒10%)]. Adolescents in Central South China had the highest rate of unsafe swimming [15% (95%CI: 12%‒18%)], of which, vocational school students accounted for the highest [15% (95%CI: 10%‒19%)]. When it comes to the prevalence of suicidal ideation, female students [16% (95%CI: 13%‒19%)] was higher than that of male students [13% (95%CI: 11%‒15%)]. Adolescents in Southwest of China had the highest rate of suicidal ideation [17% (95%CI: 10%‒25%)], of which high school students accounted for the highest [15% (95%CI: 12%‒18%)]. Finally, the detection rate of fights was 30% (95%CI: 26%‒34%) for boys and 11% (95%CI: 10%‒14%) for girls. Adolescents from Southwest of China had the highest rate [29% (95%CI: 24%‒34%)] for fights, and junior high school students accounted for the highest [26% (95%CI: 22%‒31%)]. ConclusionThe prevalence of harmful behaviors among adolescents in China is notably high, with statistical differences across gender, region, and school stages. These behaviors pose a risk to adolescent health, underscoring the need for targeted interventions by health and educational authorities.

The cases began to rise from October, reaching the peak in December and remaining at relatively high level in January and February, then decreasing to the lowest during March to September. The number of patients living in rural areas is higher than that in urban areas. Patients took average 30 (15, 90) days from onset of disease to seeing a doctor, and itching was the main complain for visiting. The locations of lesion were most common on the abdomen (63.19%, 472/747), fingertips and wrists (53.41%, 399/747), vulva (37.22%, 278/747), and extremities (30.25%, 226/747). The lesions were characterized by erythematous papules (71.62%, 535/747), nodules (47.12%, 352/747), papules (24.50%, 183/747), wheals (6.02%, 45/747), secondary infections (3.61%, 27/747), tunnels (3.08%, 23/747) and small pustules (2.14%, 16/747); the male scrotal nodules were common (48.17%, 263/546). More patients (471/747, 63.05%) first visited non-dermatology outpatient clinics, and less first visited dermatology outpatient clinics (276/747, 36.95%); the misdiagnosis rates were 55.41% (261/471) and 27.54% (76/276), respectively; 127 cases (17.00%) were misdiagnosed as eczema, 54 cases (7.23%) as allergic dermatitis, 41 cases (5.49%) as prurigo nodularis, and 35 cases (4.69%) as urticaria pulosa. Conclusions:There is a certain discrepancy in the incidence of scabies among different populations, regions and seasons, the lesions of scabies are polymorphic involving different parts of the body surface and it is easy to be misdiagnosed.

Objective:To integrate the best evidence of non-drug intervention of urinary incontinence in elderly women and to formulate practical recommendations.Methods:In this systematic review study, using “elderly woman”,“urinary incontinence”,“bladder training”,“pelvic floor muscle training”,“enuresis”,“leakage of urine” as the key words, the 6S evidence resource pyramid model was used to search in British Medical Journal best practice, Uptodate, World Health Organization, Guidelines International Network, National Institute for Health and Care Excellence, Chinese Medical Association, Scottish Intercollegiate Guideline Network, Registered Nurses Association of Ontario, Cochrane Library, The Joanna Briggs Institute (JBI), New Zealand Guidelines Group, Polish Society of Gynecologists and Obstetricians, PubMed, Embase, Medline, Web of Science, SinoMed, China National Knowledge Infrastructure, WanFang Data, etc. The evidence retrieved included evidence-based knowledge base resources, clinical practice guidelines, expert consensus, systematic review, etc. Data were retrieved from January 1, 2017 to May 1, 2022, and collated from May 2, 2022 to May 25, 2022. Two researchers independently evaluated the quality of literature and extracted data using the AGREE Ⅱ and JBI evidence-based health care center assessment tools. The JBI evidence-based health care center′s evidence pre-rating system and evidence recommendation rating system were applied to rank the evidence; and under the guidance of the evidence structure of JBI, the strength of evidence recommendation was determined and the best evidence was extracted and summarized in combination with the study group discussion and expert opinion.Results:A total of 9 articles were retrieved, including 7 guidelines and 2 systematic reviews; and 6 guidelines were classified as Grade A and 1 as grade B; both 2 systematic reviews were rated as Grade A; 84% (27/32) of the items were evaluated as “Yes”. Evidence were summarized as 34 pieces of best evidence from 6 dimensions, including “overall recommendation, evaluation of type and degree of urinary incontinence, lifestyle change, behavioral therapy, prevention of precipitating factors, intervention in special population”; the flow chart of screening, evaluation, special symptoms, life style and behavior therapy was combed, and the practical suggestions were formed.Conclusions:The overall quality of the literature on non-drug intervention of urinary incontinence in elderly women is high, and the level of evidence is high. Early identification of urinary incontinence types and assessment of disease severity, lifestyle changes, avoidance of predisposing factors and behavioral therapy are the key to non-drug treatment of urinary incontinence in those patients.

Seven dimensions such as "overall advice, health benefits, diversified sports training, aerobic training, balance training, muscle strengthening/resistance training, flexibility training" and 22 best pieces of evidence were extracted and summarized, and practical suggestions were formed.Conclusions:Medical and nursing staff should adopt evidence-based methodological practical suggestions to provide management guidance and consultation for the maintenance of physical activity ability of the elderly in the community, so as to help the elderly to maintain physical activity ability and gain health benefits.

Objective:To understand the current situation of physicians′ innovative behavior and its influencing factors in Beijing municipal hospitals, for reference in improving their innovation ability and encouraging high-quality development of public hospitals.Methods:A stratified sampling was conducted with 22 practicing (assistant) physicians in Beijing municipal hospitals as subjects. From October to November 2022, a questionnaire survey was conducted to understand the innovative behavior, innovative self-efficacy and innovative atmosphere of such practicing (assistant) physicians. SPSS 25.0 was used for descriptive analysis of the data, while t-test, variance analysis and linear regression were used for univariate analysis. Furthermore, multiple linear regression was adopted to explore the influencing factors of innovative behavior of such practicing(assistant) physicians. Results:A total of 2 178 questionnaires were distributed in this study, and 1 906 valid ones were recovered, with effective recovery of 87.51%. Scores of innovative behavior, innovative self-efficacy and innovative atmosphere of 1 906 practicing (assistant) physicians scored (4.00±0.70) points, (3.85±0.74) points and (3.98±0.66) points respectively. The results of univariate analysis showed scores of statistical significance regarding the innovative behavior of practicing (assistant) physicians with different marital status, educational background, professional title, position, department type, innovative self-efficacy level and innovative atmosphere level. Multiple linear regression results showed that position, innovation self-efficacy score, innovation atmosphere score and subordinates′ incentive mechanism, as well as teamwork and resource security had statistical significance on innovation behavior score.Conclusions:The practicing (assistant) physicians in Beijing municipal hospitals are highly enthusiastic for innovation, but their innovative behavior is expected to be upgraded. In this regard, public hospitals should improve their innovation incentive mechanism, strengthen resource assurance, encourage cooperation and exchange, and create a desirable atmosphere for innovation. Furthermore, greater supply of continuing education resources is expected, supporting these physicians in their further study, advanced education, and promotion of professional titles.

Objective:To investigate the association between single nucleotide polymorphisms (SNPs) in microRNAs (miRNAs) and the risk of chronic spontaneous urticaria (CSU) .Methods:A case-control study was conducted. A total of 98 patients with CSU (CSU group) were collected from Department of Dermatology, Affiliated Hospital of Jining Medical University from January to June in 2019, and 148 health checkup examinees (control group) were collected at the same time, all of whom were of Han nationality from Shandong province. Genomic DNA was extracted from venous blood samples, and polymorphic sites rs2431697 (miRNA-146a) , rs57095329 (miRNA-146a) , rs3746444 (miRNA-499) , rs11614913 (miRNA-196a2) and rs895819 (miRNA-27a) were analyzed for SNP genotyping by multiplex PCR amplification and single-base extension. Chi-square test was used to analyze differences in the distribution of alleles, genotypes and genetic models between the two groups, and unconditional logistic regression to analyze the relationship between gene SNPs and the risk of CSU.Results:All samples were successfully genotyped by analysis of the 5 polymorphic sites. The alleles of the miRNA-196a2 SNP rs11614913 were T/C, and the absolute frequency of T allele was 110 (56.1%) in the CSU group and 131 (44.3%) in the control group; there was a significant difference in the T/C allele frequency distribution between the two groups ( χ2 = 6.64, P = 0.010) , and the T allele might be a risk factor for CSU ( OR=1.61, 95% CI: 1.12-2.32) . In addition, the absolute frequencies of CC, CT and TT genotypes of rs11614913 were 16 (16.3%) , 54 (55.1%) , 28 (28.6%) in the CSU group, and 48 (32.4%) , 69 (46.6%) , 31 (20.9%) in the control group respectively, and there was a significant difference in the genotype distribution between the two groups ( χ2 = 8.16, P = 0.017) ; the distribution of the dominant genetic model (TT + CT vs. CC) also significantly differed between the two groups ( χ2 = 7.95, P = 0.005) , which might increase the risk of CSU ( OR=2.46, 95% CI: 1.30-4.65) . Conclusion:The miRNA-196a2 SNPs may be associated with the risk of CSU in the Han population in Shandong, China, and the rs11614913 polymorphism may increase the risk of CSU.

The immune checkpoint blockade therapy has profoundly revolutionized the field of cancer immunotherapy. However, despite great promise for a variety of cancers, the efficacy of immune checkpoint inhibitors is still low in colorectal cancer (CRC). This is mainly due to the immunosuppressive feature of the tumor microenvironment (TME). Emerging evidence reveals that certain chemotherapeutic drugs induce immunogenic cell death (ICD), demonstrating great potential for remodeling the immunosuppressive TME. In this study, the potential of ginsenoside Rg3 (Rg3) as an ICD inducer against CRC cells was confirmed using in vitro and in vivo experimental approaches. The ICD efficacy of Rg3 could be significantly enhanced by quercetin (QTN) that elicited reactive oxygen species (ROS). To ameliorate in vivo delivery barriers associated with chemotherapeutic drugs, a folate (FA)-targeted polyethylene glycol (PEG)-modified amphiphilic cyclodextrin nanoparticle (NP) was developed for co-encapsulation of Rg3 and QTN. The resultant nanoformulation (CD-PEG-FA.Rg3.QTN) significantly prolonged blood circulation and enhanced tumor targeting in an orthotopic CRC mouse model, resulting in the conversion of immunosuppressive TME. Furthermore, the CD-PEG-FA.Rg3.QTN achieved significantly longer survival of animals in combination with Anti-PD-L1. The study provides a promising strategy for the treatment of CRC.
