Objective: To investigate cardiovascular disease (CVD) prevention status among residents with intra-urban migration in Central China, so as to provide insights into targeted prevention and control of CVD. Methods: Basic data of residents aged 35 to 75 years who participated in Early Screening and Comprehensive Intervention Project for CVD high-risk populations in Central China from September 2015 to August 2020 were collected. According to birth place, type of registered residence and current residence, residents were divided into four groups: local residents in old urban area, local residents in new urban area, other urban migrants and other rural migrants. The status of CVD primary and secondary prevention, were analysed by using a robust Poisson regression model. Results: A total of 76 513 residents were recruited, including 29 420 males (38.45%) and 47 093 females (61.55%), and had a mean age of (56.36±9.84) years. There were 45 087 (58.93%) local residents in old urban area, 23 868 (31.19%) local residents in new urban area, 5 668 (7.41%) other urban migrants and 1 890 (2.47%) other rural migrants. After adjusting for variables such as age, gender and educational level, the results of robust Poisson regression analysis showed that compared with local residents in old urban area, local residents in new urban area had lower compliance rates of non- or moderate-drinking (RR=0.987, 95%CI: 0.975-1.000) and healthy diet (RR=0.535, 95%CI: 0.365-0.782), lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.616, 95%CI: 0.511-0.741), lower awareness (RR=0.873, 95%CI: 0.782-0.974) and control rates (RR=0.730, 95%CI: 0.627-0.849) of hypertension; other urban migrants had higher compliance rate of non-smoking (RR=1.045, 95%CI: 1.017-1.075); other rural migrants had lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.826, 95%CI: 0.707-0.966). Conclusion The CVD primaryprevention among local residents in new urban area is relatively poor among four groups of residents in Central China, and key interventions are needed.

The experience of professor YANG Wen-Hui in treating lumbago disease with YANG's Baliao-acupoints moxibustion is introduced in this paper.YANG Wen-Hui believes that the basic pathogenesis of lumbago disease is'cold causes lower back pain',and based on the philosophical idea of'harmony in Shushu(the ways to cultivate health)',he proposes'YANG's Baliao-acupoints moxibustion'for the treatment of lumbago disease.According to the patient's condition,professor YANG used the acupoints of Shangliao(BL31),Ciliao(BL32),Zhongliao(BL33),and selected the moxa cone like jujube core,soybean or wheat grain,and applied moxibustion with the technique of'San Yang Kai Tai'or'Ruo feng Chui Yun',the number of moxibustion is proportional to the age of the patient.YANG's Baliao-acupoints moxibustion in treating lumbago disease exerts highly and remarkable clinical efficacy,and it was widely acclaimed by the patients.

Following the principles of evidence-based medicine,in accordance with the structure and drafting rules of standardized documents,based on literature research,according to the characteristics of chronic cough in children and issues that need to form a consensus,the TCM Guidelines for Diagnosis and Treatment of Chronic Cough in Children was formulated based on the Delphi method,expert discussion meetings,and public solicitation of opinions.The guideline includes scope of application,terms and definitions,eti-ology and diagnosis,auxiliary examination,treatment,prevention and care.The aim is to clarify the optimal treatment plan of Chinese medicine in the diagnosis and treatment of this disease,and to provide guidance for improving the clinical diagnosis and treatment of chronic cough in children with Chinese medicine.

Chondroitin sulfate sodium is a sulphated glycosaminoglycan composed of repeating disaccharide units of D-glucuronic acid and N-acetyl-D-galactosamine,prepared from the cartilage tissue of land or marine animal by a specific extraction and purification process.Chondroitin sulfate sodium is considered to have anti-osteoarthritis effect and many other potential physiological activities.It has broad application prospects and development space in the fields of health food,cosmetics,and drugs.This paper reviews the preparation process of chondroitin sulfate sodium,development and problems of microbial synthesis technology and the research status of anti-osteoarthritis activity based on cells models,animal models and clinical randomized controlled trials(RCT).The limitations of current research are analyzed and corresponding strategies are proposed to provide reference for further standardization and development of chondroitin sulfate sodium.

The purpose of this study was to identify the tick species native to Xindi Township,Yumin County,Xinjiang,China.Preliminary morphological identification of parasitic ticks collected from animals in the area was conducted with an ultra-depth of field three-dimensional VHX 600 digital stereo microscope.Total DNA of the ticks was extracted,amplified by PCR based on the COI and ITS2 gene loci,and the posi-tive PCR products were sequenced.The sequence were a-ligned with reference sequences from the NCBI database were aligned with the Basic Local Alignment Search Tool.A genet-ic phylogenetic tree was generated with the neighbor-joining method of MEGA 7.0 software to determine the evolutionary biological characteristics of ticks.Morphological identification showed that the ticks collected from Xindi Township of Yu-min County were consistent with the characteristics of Hya-lomma asiaticum.An evolutionary tree based on the COI and ITS2 gene sequences showed that the ticks collected in this study were clustered with known H.asiaticum sequences.The PCR products of COI and ITS2 were sequenced and compared,which confirmed that the collected tick species were H.asiaticum,in agreement with the morphological and molecular biological results.These findings help to clarify the distribution of ticks in Xindi Township of Xinjiang,and provide basic data for the analysis of tick genetic and evolutionary characteristics,as reference for surveillance and control of ticks in the Xinjiang Uygur Autonomous Region.

AIM To investigate the protective effect of Mongolian medicine Naru-3 on rat rheumatoid arthritis(RA)using imaging method.METHODS With the rats divided into the normal group,the model group,the positive medicine group,and the low,medium and high dose Naru-3 groups(0.1,0.2 and 0.4 g/kg),the rat model of collagen-induced arthritis(CIA)was established by immune induction method.After 4 weeks of corresponding drug administration,the rats had their changes of arthritis index(AI)level and body weight observed;their serum levels of VEGF,TNF-α and IL-1 detected by ELISA;their synovial hyperplasia and neovascularization evaluated by high-frequency ultrasound and contrast-enhanced ultrasound(CEUS);their bone destruction of ankle joint evaluated by X-ray and high-resolution micro-CT;and their synovial membrane and expressions of CD31,VEGF,TNF-α and IL-1 β observed by HE and immunohistochemistry.RESULTS Compared with the model group,the Naru-3 groups displayed increased rat weight(P＜0.05);no significantly changed AI score(P＞0.05);and overally decreased levels of serum VEGF,TNF-α,synovial membrane thickness,blood flow signal by power Doppler imaging(PDI)and contrast intensity revealed,X-ray score,and CD31 expression(P＜0.05),in addition to the decreased level of IL-1 and HE score in high-dose group(P＜0.05).CONCLUSION Naru-3 is protective to the joint tissue in rat model of RA through alleviating synovitis,bone erosion and delaying the progress of the disease by inhibiting synovial neovascularization and inflammatory cytokines.

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.
