OBJECTIVE: To compare the clinical efficacy of jingjin needling combined with rehabilitation training and conventional acupuncture combined with rehabilitation training for post-stroke spastic paralysis. METHODS: A total of 60 patients with post-stroke spastic paralysis were randomly divided into an observation group and a control group, 30 cases in each one. Both groups received conventional rehabilitation training. In the observation group, jingjin needling was applied at tendon blockage points of the shoulder, elbow, wrist, hip, knee, and ankle. In the control group, conventional acupuncture was applied at Jianyu (LI15), Quchi (LI11), Hegu (LI4), Biguan (ST31), Fengshi (GB31), Taichong (LR3), etc. on the affected side. Treatment was given once daily, 5 days a week for 4 weeks in both groups. The scores of clinical spasticity index (CSI), modified Ashworth scale, modified Barthel index (MBI), and Fugl-Meyer assessment scale (FMA) were evaluated before and after treatment, and the onset time was compared between the two groups. RESULTS: After treatment, the scores of CSI and modified Ashworth scale were decreased compared with those before treatment (P<0.001), while the scores of MBI and FMA were increased compared with those before treatment (P<0.001) in the two groups. After treatment, the scores of CSI and modified Ashworth scale in the observation group were lower than those in the control group (P<0.05), the MBI score in the observation group was higher than that in the control group (P<0.05). There was no statistically significant difference in FMA scores between the two groups (P>0.05). The onset time of the observation group was earlier than that in the control group (P<0.05). CONCLUSION Both jingjin needling combined with rehabilitation training and conventional acupuncture combined with rehabilitation training can effectively treat post-stroke spastic paralysis, jingjin needling combined with rehabilitation training exhibits better therapeutic effect and rapider onset.

Collagen-based materials, renowned for their biocompatibility and minimal immunogenicity, serve as exemplary substrates in a myriad of biomedical applications. Collagen-based micro/nanogels, in particular, are valued for their increased surface area, tunable degradation rates, and ability to facilitate targeted drug delivery, making them instrumental in advanced therapeutics and tissue engineering endeavors. Although extensive reviews on micro/nanogels exist, they tend to cover a wide range of biomaterials and lack a specific focus on collagen-based materials. The current review offers an in-depth look into the manufacturing technologies, drug release mechanisms, and biomedical applications of collagen-based micro/nanogels to address this gap. First, we provide an overview of the synthetic strategies that allow the precise control of the size, shape, and mechanical strength of these collagen-based micro/nanogels by controlling the degree of cross-linking of the materials. These properties are crucial for their performance in biomedical applications. We then highlight the environmental responsiveness of these collagen-based micro/nanogels, particularly their sensitivity to enzymes and pH, which enables controlled drug release under various pathological conditions. The discussion then expands to include their applications in cancer therapy, antimicrobial treatments, bone tissue repair, and imaging diagnosis, emphasizing their versatility and potential in these critical areas. The challenges and future perspectives of collagen-based micro/nanogels in the field are discussed at the end of the review, with an emphasis on the translation to clinical practice. This comprehensive review serves as a valuable resource for researchers, clinicians, and scientists alike, providing insights into the current state and future directions of collagen-based micro/nanogel research and development.

Objective:Based on the analysis of case report and case series studies involving COVID-19 pregnant women in China, we aimed to discuss the updated management requirements for publication of scientific papers at hospitals in the new circumstances and context.Methods:The case report and case series studies published by domestic scholars in the early stage of COVID-19 outbreak were retrieved. Bibliometrics were used to analyze the research time, research content and research objects of the included literatures.Results:Nearly 200 cases (55%) of the 360 cases of COVID-19 pregnant women could not be clearly excluded from the possibility of repeated reporting. However, all these cases were not disclosed in the paper for possible repeated report.Conclusions:Potential repeated report problem may cause trouble for later meta-analysis, which also may have negative impact for the development of clinical guidelines. The departments of scientific research management at hospital should pay more attention to the management of patient′s data in scientific papers, so that it can better serve the accurate assessment of disease characteristics and epidemic situation, as well as the scientific formulation of clinical guidelines and control strategies.

Background::High sodium intake is an important risk factor for hypertension and cardiovascular disease. However, the association between gut microbiota composition and metabolomic profiles with dietary sodium intake and blood pressure (BP) is not well-understood. The metabolome, microbiome, and dietary salt intervention (MetaSalt) study aimed to investigate microbial and metabolomic profiles related to dietary sodium intake and BP regulation.Methods::This family-based intervention study was conducted in four communities across three provinces in rural northern China in 2019. Probands with untreated prehypertension or stage-1 hypertension were identified through community-based BP screening, and family members including siblings, offspring, spouses, and parents were subsequently included. All participants participated in a 3-day baseline examination with usual diet consumption, followed by a 10-day low-salt diet (3 g/d of salt or 51.3 mmol/d of sodium) and a 10-day high-salt diet (18 g/d of salt or 307.8 mmol/d of sodium). Differences in mean BP levels were compared according to the intervention phases using a paired Student's t-test.Results::A total of 528 participants were included in this study, with a mean age of 48.1 years, 36.7% of whom were male, 76.8% had a middle school (69.7%) or higher (7.1%) diploma, 23.4% had a history of smoking, and 24.4% were current drinkers. The mean arterial pressure at baseline was 97.2 ± 10.5 mm Hg for all participants, and significantly decreased during the low-salt intervention (93.8 ± 9.3, P < 0.0001) and subsequently increased during the high-salt intervention (96.4 ± 10.0, P < 0.0001). Conclusions::Our dietary salt intervention study has successfully recruited participants and will facilitate to evaluate the effects of gut microbiota and metabolites on BP regulation in response to sodium burden, which will provide important evidence for investigating the underlying mechanisms in the development of hypertension and subsequent cardiovascular diseases.Trial registration::The study was registered in the Chinese Clinical Trial Registry database (ChiCTR1900025171).

Objective: To survey the children under 7 years of age in nine cities of China for a better understanding of the current situation of childhood stunting. Methods: According to a stratified cluster sampling design, a cross-sectional survey on children under 7 years of age was carried out in 9 cities (Beijing, Harbin and Xi′an in northern China; Shanghai, Nanjing and Wuhan in central China; and Guangzhou, Fuzhou and Kunming in southern China) from June to November in 2016. A total of 110 499 children were recruited. Height of children was evaluated using the growth standards for Chinese children (2009 edition) .Children with height less than the 3rd percentile of the growth standards were considered as stunting, and children with height between the 3rd and 10th percentiles of the growth standards were considered as relatively short stature. Chi-square test was used for comparison between data of boys and girls, urban and suburban, as well as among different ages and regions. Results: Totally 113 084 children under 7 years of age should be investigated and actually 110 499 children were investigated, with a rate of 97.7%. The prevalence of stunting was 1.9% (2 141/110 499) among all the children. The prevalence of stunting in urban children (1.6%, 904/55 524) was lower than that in suburban children (2.3%, 1 237/54 975, χ²=56.246, P<0.01). The gender difference in stunting prevalence was not statistically significant (1.9% (1 121/57 921) in boys and 1.9% (1 020/52 578) in girls, χ²=0.003, P=0.965). The prevalence of stunting decreased with age for children younger than 3 years, from 1.8% (312/17 080) in 0-<1 year of age group to 1.2% (168/13 740) in 2-<3 years of age group, but increased to 2.2% (240/11 073) at 6-<7 years group. Comparison among different regions showed that the stunting prevalence in southern region was higher than those in the central and northern regions (0.9% (193/20 374) in northern urban, 0.8% (154/18 486) in central urban, and 3.3% (557/16 664) in southern urban children), showing a statistical significance (χ²=437.736, P<0.01); 1.1% (241/21 924) in northern suburban, 1.4% (227/16 775) in central suburban and 4.7% (769/16 276) in southern suburban children, showing a statistical significance (χ²=646.533, P<0.01). In urban areas, the difference between the central and northern regions showed no statistical significance (χ²=1.429, P=0.232) and the stunting prevalence of central Chinese children was slightly higher than that of northern Chinese children in suburban areas (χ²=5.130, P=0.024). Among the nine cities, the stunting prevalence of Guangzhou (6.1%, 613/10 019) was higher than those of other cities (χ²=1 559.64, P<0.01). Among the stunting children, 78.4% (1 679/2 141) were classified as borderline or mild and only 7.2% (154/2 141) were classified as severe. The prevalence of relatively short stature was 5.2% (5 721/110 499). Conclusions The prevalence of stunting among children under 7 years of age in nine cities of China is low and most of the stunting children were classified as mild; the prevalence of stunting in suburban children is higher than that in urban children; the gender difference show no statistical significance; and the prevalence of stunting in southern Chinese children is higher than those in central and northern Chinese children.

Objective:To investigate the clinical characteristics and therapeutic methods of coronary artery aneurysm (CAA).Methods:The clinical data and coronary angiography of 32 patients confirmed by coronary angiography as coronary aneurysm in Shenzhen Hospital of Southern Medical University and Shenzhen People′s Hospital were collected. They were followed up, and the different therapeutic methods were analyzed.Results:Thirty-two cases (1.8%) of coronary artery aneurysms were found in 1 778 patients undergoing coronary angiography. The main sites of coronary ectasia were right coronary artery, anterior descending branch and circumflex branch, and the left main branch was rare. Among the patients with coronary artery aneurysms, there were 25 patients with coronary artery stenosis. All the 32 patients were given anticoagulant, antiplatelet, improvement of coronary spasm and statin therapy, among whom 2 patients were treated with stent implantation and 6 patients were treated with coronary artery bypass graft (CABG) and ligation of coronary aneurysm. During the follow-up (average 15 months) of 1 patient, acute myocardial infarction reoccurred, and coronary angiography indicated that the stenosed coronary segments after artery ectasia was occluded because of thromboembolism. In the remaining patients, there were no major cardiovascular events such as angina pectoris, acute myocardial infarction and sudden cardiac death.Conclusions:Coronary artery aneurysm is not a rare heart disease. Coronary thromboembolism, thrombosis and vasospasm are the main causes of angina pectoris and myocardial infarction. Anticoagulant, antiplatelet, antispasmodic drugs and suitable coronary artery bypass can significantly improve the clinical prognosis of patients with coronary artery aneurysm.
