Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Objective:This study aims to obtain the prevalence and features associated with Violence Against Children (VAC) in China and, thus, formulate a prevention strategy.Methods:The mortality-related data of VAC was sourced from the National Disease Surveillance Points System (DSP) during 2013-2021. We analyzed the DSP data regarding children aged 0-17 years old who died from violence. The hospital cases of VAC was sourced from the National Injury Surveillance System (NISS), 2013-2021. We analyzed the data from NISS with the parameter of "intentional injury" caused by VAC in children aged between 0-17 years. Using robust linear regression, we analyze the time trend in the proportion of violence incidence. To understand the variations in the incidence of different types of violence across genders, we apply the chi-square test and adjusted Pearson residuals.Results:The overall trend of death caused by VAC has declined; it was reduced to 0.14/100 000 in 2021 from 0.33/100 000 in 2013. In 2021, male VAC mortality (0.15/100 000) was higher than females (0.13/100 000). The proportion of VAC cases to all injury cases has declined from 3.34% in 2013 to 2.29% in 2021. Among 9 344 VAC cases supervised by hospitals in 2021, the number of males (7 503 cases) was around 4 times that of females (1 841 cases), and the top three modes of violence were blunt tools (64.77%), falls (7.46%) and sharp instruments (6.18%), and 45 cases of sexual violence included 38 girls and 7 boys.Conclusions:The declining death rate due to VAC may be related to the benign development of Chinese society. Prevention strategies targeting training in parenting skills and problem-solving should be prioritized.

Objective To investigate the relationship between sleep fragmentation(SF)parameters and left ventricular structure in a community-based elderly population using data collected from the Multi-Ethnic Study of Atherosclerosis(MESA)cohort.Methods A total of 1 404 participants from the MESA cohort who underwent polysomnography(PSG)and cardiac magnetic resonance(CMR)were included.PSG was used to assess SF parameters,including wake after sleep onset(WASO),arousal index-total(ArI-total),arousal index-rapid eye movement(ArI-REM),and arousal index-non-rapid eye movement(ArI-NREM).Left ventricular end-diastolic mass(LVEDM)was measured via CMR.Linear regression was employed to analyze the relationship between SF parameters and left ventricular mass to height ratio(LVHi).Results Univariate linear regression analysis showed that WASO[β 0.134;95％confi-dence interval(CI)0.023-0.052;P＜0.001],ArI-total(β 0.184;95％CI 0.203-0.362;P＜0.001),ArI-REM(β 0.116;95％CI 0.100-0.260;P＜0.001)and ArI-NREM(β 0.175;9 5％CI 0.176-0.323;P＜0.001)were positively correlated with LVHi.After adjust-ment for confounding factors in multivariate linear regression analysis,WASO(β 0.045;95％CI 0.001-0.024;P=0.033)was positively correlated with LVHi.WASO(β 0.089;95％CI 0.006-0.034;P=0.006)was significantly associated with increased LVHi in the female group but not in the male group.Conclusion In an ethnically diverse cohort,WASO is significantly associated with increased LVHi after adjustment for potential confounders,especially in the female elderly population.

Objective To evaluate the efficacy of endovascular treatment for ruptured descending thoracic aortic aneurysm(rDTAA),and to summarize the treatment experience.Methods The clinical data of 8 patients with rDTAA,who were admitted to the Department of Vascular Interventional Surgery,Zhangjiajie Municipal People's Hospital of China to receive treatment between January 2016 and June 2023,were retrospectively analyzed.The patients included 4 males and 4 females,with a median age of 70.5 years(61-78 years).Preoperative computed tomography angiography(CTA)was performed in all the 8 patients,and the diagnosis of rDTAA complicated by hematoma in the thoracic cavity and/or mediastinum was confirmed.Emergency thoracic endovascular aortic repair(TEVAR)was carried out in all the 8 patients.Results Complete isolation of the thoracic descending aortic aneurysm was achieved in 6 patients,and 2 of them received reconstruction of left subclavian artery by using chimney stent technique.The remaining two patients had a small amount of type Ⅰa endoleak,which disappeared after implantation of a cuff stent at the proximal site.During hospitalization,one patient died of septic shock caused by thoracic aortic-esophageal fistula,and 3 patients developed respiratory failure after operation,which was recovered after thoracic drainage,anti-infection medication and ventilator-assisted breathing therapy.Two patients developed postoperative ischemic stroke,one of them presented as grade Ⅲ motor muscle weakness on the affected side accompanied by speech impairment,and the another patient presented as grade Ⅳ motor muscle weakness on the affected side accompanied by speech impairment.During the follow-up period,one patient died of sudden chest pain 7 months after surgery,and another patient who had not received chimney stent implantation developed type Ⅰa endoleak 18 months after operation,which disappeared after implantation of a cuff stent at the proximal site.The remaining 5 patients showed good clinical condition during the follow-up period.Conclusion For the treatment of rDTAA,TEVAR is clinically safe and effective.

Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Objective:To compare the quality of Astragali Radix at different harvest time; To revise the content determination indexes of Astragali Radix in Chinese Pharmacopoeia. Methods:An Agilent Eclipse XDB-C18 column (4.6 mm × 150 mm, 5 μm) was used for the determination of saponins with acetonitrile-water solution as mobile phase in a gradient mode. The drift tube temperature of ELSD was 60 ℃; the pressure was 30 psi; the gain was 800 ℃; the flow rate was 1.0 ml/min; the column temperature was 30 ℃; the injection volume was 20 μl; the acetonitrile-0.2% formic acid solution was used as mobile phase for the determination of flavonoids in a gradient mode; the flow rate was 1.0 ml/min; the detection wavelength was 260 nm; the column temperature was 30 ℃; the 10 μl was injected. The limited range as an indicator for determining Astragali Radix content was determined by investigating the extraction method and extraction time of Astragaloside Ⅰ and detecting the content of Astragaloside Ⅰ in 12 batches of Astragali Radix from different origins. The moisture, total ash, and water-soluble extracts in Astragali Radix were determined according to the drying method, total ash determination method, and cold soaking method in the four parts of Chinese Pharmacopoeia (2020 edition), respectively. Results:The content of total saponins in Astragali Radix harvested in spring and autumn in different origins was not significantly different, but the content of total flavonoids was significantly different. Except for H11, the content of Astragaloside Ⅰ in the other batches of Astragali Radix was ≥ 0.05%, so the content limit of Astragaloside Ⅰ was proposed to be≥0.05%. The results of moisture, total ash and water-soluble extracts in the 12 batches of Astragali Radix all meet the requirements in the Chinese Pharmacopoeia. Conclusions:Astragali Radix harvested in autumn is with higher content of active components and better quality. At the same time, this study can provide a reference that the new version of Chinese Pharmacopoeia can revise the Astragaloside Ⅳ in the content determination index of Astragali Radix to Astragaloside Ⅰ .

Objective: To understand the injuries among 16 459 left-behind children from 27 poor rural areas in 12 provinces of China, 2016. Methods: Data were collected from the survey of 'Health Service Needs Assessment’ (HSNA) program on left-behind children, from poor rural areas in the middle and western parts of China. Factors including causes, types, locations, related activities, ways of treatment and outcomes among left-behind children with injuries in 2016, were described and analyzed by gender and age groups. Results: In 2016, per-person and person-time incidence rates of injuries were 8.88% and 11.21%, among the 16 459 left-behind children from 27 poor rural areas in 12 provinces of China, both higher in boys, than in girls. Most injuries were unintentional with its proportion higher in older children. The main types of injuries were seen as falls, blunt and sharp injuries, with burns and animal injuries more common in younger children. Injuries among left-behind children mainly took place at home, kindergarten/school, and on the highways/streets/roads, during playing. Most common ways of treatment would include at the emergency settings, self-treated, with older children more likely to treat by themselves. Most injuries were cured. Conclusions In programs on prevention and control of injuries targeting the left-behind children in poor rural areas, special attention should be given to older boys, on falls and blunt/sharp injuries, at home or kindergarten/school. Education programs should pinpoint on self-rescue skills and guidance on kids by the parents, with behavioral norms and social support included. Related comprehensive prevention and control mechanism should be developed in families, schools and communities, with medical resources and insurance mechanism explored to serve these population and districts, including those left-behind children.

Objective To explore the clinical phenotype of 22q11.2 deletion syndrome with imperforate anus. Methods The clinical diagnosis and treatment of one case of 22q11.2 deletion syndrome complicated with anal atresia were retrospectively analyzed. Gene and phenotype of this disease were analyzed, and the related literature was reviewed. Results An elder male test tube infant of twins, born to a G2P2 mother were found to have special facial features, cleft palate, congenital heart disease, and imperforate anus after birth. A genome-wide microarray scan revealed 22q11.2 deletion syndrome. In related literatures, 22q11.2 deletion syndrome could be affected by TBX1 gene, histone modification, Ranbp1 gene, and even microRNA; while imperforate anus were influenced by multiple elements such as genetic, maternal, and environmental factors and multiple embryonic developments related genes could be involved in its pathogenesis. Conclusions Congenital imperforate anus and 22q11.2 deletion syndrome are mostly sporadic cases in epidemiology and are incidental accidents in development. Whether there is a common interaction factor between them needs to be further studied and defined.

Objective To investigate the distribution of age and relationship of ESR with HCT.Methods The HCT,age and ESR datas of the patients which all ages were above 40 years were Collected,then count the mean and standard deviation x±s with different groups of HCT,t test was made to identify the significance of difference.Results HCT:The levels of hct in males was 0.47±0.26 in higher groups of HCT,0.39±0.27 in normal groups and 30.01 ±3.59 in lower groups.The levels of HCT in fe-males was 0.42±0.17 in higher groups,0.30±0.36 in normal groups,0.27±0.45 in lower groups;Age:The average age in males was 57.41±10.62 years in higher HCT groups of patients,67.23 ±12.75 in lower hct groups,there were significantly difference between them.The avarage age in females was 60.70 ± 11.60 in higher HCT groups of patients,61.60 ± 12.40 in lower HCT groups,there were no significantly difference between them.ESR:The levels of ESR in males was (3.95 ±3.26)mm/h in higher HCT groups,(61.61±40.04)mm/h in lower HCT groups;The ESR in females was (28.26±28.62)mm/h in higher HCT groups, (60.20±43.71)mm/h in lower HCT groups,there were significantly difference between different groups included both males and femals.Conclusion When the HCT were decreased,the age and ESR were increased in males,the ESR were also increased but had no relationship with ages in females.Conjuction the age and ESR,it could improve the prevention and monitoring in heart-brain blood disease through the HCT.

Objective To retrospect the literature review related psychological resilience of cancer patients at home and abroad in recent 10 years, and analyze the application status, main problems and provide the corresponding countermeasures. Methods The literature review was searched by the way of key words in China National Knowledge Infrastructure database ( CNKI) and basic search in Pubmed from 2006 to 2015. Then the year, number, design and contents of the research were concluded into analysis. Results Research about psychological resilience of cancer patients was developed late but the number was rising; the research design were mostly observational study and lots of research focused on the adult patients with breast cancer or gynecological cancer; research contents mainly included current situation and affecting factors of quantitative analysis.Conclusions We find out psychological resilience of cancer patients has been attracted great attention by domestic scholars but with limited research content, uneven distribution of study. The experimental research, qualitative research has not been carried out, so the quality of nursing literature still needs to be improved.
