In order to develop safe training intensity and training methods for the passive balance rehabilitation train- ing system, we propose in this paper a mathematical model for human standing balance adjustment based on T-S fuzzy identification method. This model takes the acceleration of a multidimensional motion platform as its inputs, and human joint angles as its outputs. We used the artificial bee colony optimization algorithm to improve fuzzy C--means clustering algorithm, which enhanced the efficiency of the identification for antecedent parameters. Through some experiments, the data of 9 testees were collected, which were used for model training and model results validation. With the mean square error and cross-correlation between the simulation data and measured data, we concluded that the model was accurate and reasonable.

ssociation of snoring with metabolic syndrome in the four ethnic populations in Boertala region of Xinjiang.

Taking human umbilical vein endothelial cells (HUVEC)as experimental model which can simulate tumor-derived vascular endothelial cells;the effects of CPU-XT-008;an amino sugar derivative of combretastatin A-4 (CA-4);on HUVEC proliferation;cell cycle distribution;tubulin polymerization and the key regulatory pro-tein of cell cycle were studied.The effect of CPU-XT-008 on the proliferation of HUVEC was determined by MTT assay.The cell cycle distribution caused by CPU-XT-008 was detected by flow cytometry.Immunofluorescence was used to detect apoptosis and tubulin polymerization.The expressions of Cyclin B1;Cdc2 and β-tubulin were detected by Western blotting.Results demonstrated that CPU-XT-008 could target tubulin and inhibit the poly-merization ofβ-tubulin;and it could lead to G2/M cell cycle arrest in HUVEC by up-regulating Cyclin B1 expres-sion and down-regulating Cdc2 and p-Cdc2 expression;which resulted in inhibiting the proliferation of HUVEC and inducing its apoptosis.

BACKGROUND: Long noncoding RNAs play a role In transcription and post-transcrlptlonal levels, participate in the regulation of bone regeneration, and are closely related to osteoarthritis as well.  OBJECTIVE: To review the research progress of long noncoding RNAs in bone regeneration and osteoarthritis. METHODS: A computer-based search of CNKI, PubMed, and Elsevier was performed for relevant articles regarding long noncoding RNAs in bone regeneration and osteoarthritis published from January 2000 to June 2019, including review, basic research and clinical research. The search terms were “LncRNA; bone; bone regeneration; osteoarthritis” in Chinese and English. After preliminarily reading titles and abstracts, irrelevant articles were excluded. According to the inclusion and exclusion criteria, 64 articles were finally included in result analysis. RESULTS AND CONCLUSION: Bone regeneration is a complex process involving the interaction of osteoblasts and osteoclasts. Long noncoding RNAs are involved in the differentiation of osteoblasts and the production of osteoclasts, which play an important role in the balance of osteoblasts and osteoclasts. Therefore, it is a key molecule of bone regeneration. Long noncoding RNAs are involved in the occurrence and development of osteoarthritis and differentially expressed in osteoarthritis patients and healthy people, some of which are elevated and some are decreased in osteoarthritis patients. Thus, defining their respective expression differences and functions is of great significance for the prevention and treatment of osteoarthritis.

OBJECTIVETo study the clinical effect of the Gartland III humerus supracondylar fractures in children by manipulative reduction and Kirschner wire percataneous internal fixation.

METHODSFrom July 2010 and July 2013, 60 patients with Gartland III humerus supracondylar fracture were selected and divided into treatment group and control group. In the treatment group 32 patients were treated with traditional bone setting tetradeca-manipulative reduction and percataneous Kirschner wire internal fixation,included 18 males and 14 females with an average age of (7.8 +/- 2.7) years old ranging from 5 to 11; in the control group 28 patients were treated with open reduction and Kirschner wire internal fixation,included 16 males and 12 females with an average age of (7.2 +/- 3.0) years old ranging from 4 to 12. The motion range of the elbow joint,the time of fracture clinical healing, and the effect after 6 months of Flynm clinical functional assessment standards were observed and compared.

RESULTSThe average fracture healing time of the control group (5.01 +/- 0.43) weeks was longer than that of the treatment group (4.29 +/- 0.29) weeks (t = 7.49, P = 0.00). At 6 months after treatment,the elbow motion range of the treatment group (146.02 +/- 2.28) was more than that of the control group (140.76 +/- 4.42) (t = -5.67, P = 0.00). At 6 months after treatment, according to Flynn evaluation, in the control group,there were 7 cases as excellent, 16 as good, 4 fair, 1 poor; in the treatment group, excellent in 21, good in 9, fair in 2 (U = 3.09, P = 0.002).

CONCLUSIONManipulative reduction and Kirschner wire percataneous internal fixation for treatment of children's Gartland III humerus condyle fractures can shorten fracture clinical healing time and the clinical curative effect is better.

Objective By means of analyzing the antihypertensive use of hypertension patients of Guiyang in 2013 and impact factors for basic drug use,to evaluate the impacts of the essential medicines list in place in Guiyang to hypertension patients in communities in Guiyang.Methods 969 hypertension patients were surveyed with structured questionnaire of stratified random sampling at 6 community health centers in Guiyang city.Results Hypertension patients in communities averaged 1.4 types of antihypertensive,and the essential medicines used accounted for 39.8％of all the antihypertensive.The distribution differences of the ratio of essential medicines use are significant interms of age,gender,and household annual income.Use ratio of non-essential medicines of the 55～64 age group and 65～74 age group are 3.48 times and 0.47 times over that of the 75 and above age group.For hypertension patients of low income and medium income,their probable use of non-essential medicines is 2.05 and 2.87 times that of high income households.Conclusion As the use ratio of hypertension patients in Guiyang is relatively low,and the factors for it are age and household income,focused intervention is recommended for the 65～74 age group and low-income households,for the purpose of high use ratio of essential medicines of such people.

Objective:Mutation in the gap junction beta 6 (GJB6) gene has been reported to be associated with an autosomal dominant disorder hidrotic ectodermal dysplasia (HED), characterized by congenital nail clubbing, alopecia and palmoplantar keratoderma. The aim of this study is to investigate relationship between genetic mutation in GJB6 and HED in an affected Chinese family.
Methods:We selected a Chinese HED family consisting of a total of 17 individuals including 8 HED patients (5 males and 3 females). The whole coding region of GJB6 was amplified by polymerase chain reaction and sequenced.
Results:Sequence analysis identified a heterozygous missense mutation c.31G>A (p.G11R) in GJB6 gene of affected individuals, but not in healthy individuals.
Conclusion:A c.31G>A (p.G11R) missense mutation in GJB6 gene is the genotypic characteristic for HED in Chinese population.

Objective To investigate the application value of the Perclose Proglide vascular devices in the thoracic endovascular aortic repair (TEVAR) of aortic dissection.Methods Retrospective analysis of 106 patients who underwent TEVAR for Standford B type aortic dissection were performed.The femoral lumen was measured by CTA be fore,1 month and 1 year after TEVAR.Results A total of 223 Perclose Proglide vascular closure devices were used in the 106 patients,including 97 patients with 2 devices,7 patients with 3 devices,2 patients with 4 devices.The puncture femoral artery diameters had no significant differences between before and 1 month,1 year after TEVAR (all P ＞0.05).Conclusion Per close Proglide vascular closure devices can be effectively and safely used in the TEVAR,which has little influence on the femoral artery diameter,and is worth to be applied in the clinics extensively.
