Objective To observe the clinical efficacy of Daidzein Capsules(DC) on female climacteric syndrome.Methods Sixty eight patients with climacteric syndrome were randomized into DCgroup(n=37) and Gengnian'an control group (n=31).The treatment group and the control group were orally administered DC 150 mg and Gengnian'an Tablet 4.8 g,three times a day,respectively.The course of treatment lasted three months.Results The total effective rate in DC group was 91.89 %,which was superior to that in the control group.Time of drug becoming effective was shorter in DC group than that in the control group.After treatment,the level of E2 was significantly increased and the content of LH decreased significantly in DC group.Conclusion DC is safe and effective for the treatment of female climacteric syndrome.

Objective To explore and analyze the timing and postoperative effect of proximal femoral nail anti-rotation( PFNA) for the treatment of elderly femoral intertrochanteric fracture. Methods From September 2011 to March 2013, there were 36 elderly patients with femoral intertrochanteric fractures in our hospital, including 6 cases of type A1, 16 cases of type A2, and 14 cases of type A3. All the 36 pa-tients received PFNA and systematic rehabilitation exercise. Treat the underlying disease and strengthen the nursing to prevent thrombosis at the same time. Hip joint function was evaluated by the Harris score system. Results The average hospitalization of patients is 4 weeks. The wound healing was good in 30 cases and wound infection occured in 2 cases who recovered after subsequent treatment, and the other 4 pa-tients died due to complicated internal medicine diseases. 21 cases of patients were followed up,and their hip joint function recovered well according to the Harris score system, including 12 cases of excellent, 6 cases of good, and 3 cases of eligible, with an excellent and good rate of 85%. Conclusion The application of PFNA for the treatment of elderly femoral intertrochanteric fractures has the advantages of less damage to the local blood supply and better recovery of fracture healing and hip joint function, which is an ideal treatment for the elderly pa-tients with femoral intertrochanteric fractures.

Objective To investigate the effects of Modified Siwutang aqueous extract (mSWT) on bone marrow cell mobilization and plantation in mice after acute myocardial infarction (AMI).Methods The AMI model was established by ligating the left anterior descending artery in Kunming mice.Bone marrow cells were marked by injection of DAPI into the cavitas medullaris of shin bones.Mice were administered with mSWT 60 mg/kg by intragastric administration once a day after surgery.After haematoxylin-eosin and immunofluorescent staining,the plantation of bone marrow cells in AMI area and microvessel density were detected by histopathological assay.The EPCs proportion of peripheral blood was measured by flow cytometry.Results Compared with model mice,infarct size obviously was decreased after mSWT 60 mg/kg treatment,with EPCs ratio increased significantly.Inflammatory cell infiltration of myocardium was much less.Myocardium cellular degeneration and necrosis,fibrosis were reduced,which survival cardiac muscle tissue was increased.DAPI positive cells of plantation and survive were found in AMI region of mSWT group.The number of positive cells were increased in mSWT group than that of model group.There were lot of microvessels of vWF positive expresseion in mSWT than model group.Conclusion:mSWT significantly improved histopathology of AMI mice.The mechanism may be involved in moved bone marrow cells,homed to AMI area and promote angiogenesis.

Objective To investigate the effects of AGEs-RAGE on the apoptosis of GLUTag cells and explore the possiblc mechanism.Methods GLUTag cells treated with 0、100、200、300μg/ml of AGEs for 24h were examined for gene and protein expression of RAGE using RT-PCR and western blotting,respectively.GLUTag cells were randomly divided into four groups:control,200μg/ml AGEs,AGEs+siRNA-RAGE and AGEs+apocynin.The protein expression of p22phox、p47phox 、Bcl-2、Bax in the cells were detected with western blotting.The reactive oxygen species (ROS) levels were examined using 2'7'-dichlorodihydroflur-rescein diacetate (DCFH-DA) and the apoptosis of L cells were tested by AnnexinV-FITC/PI.Results AGEs increased thc cxpression of RAGE in a dose dependent manner.Treatment with AGEs induced a significant increase in the expression of p22phox,p47phoxand the activity of ROS,caused up-regulation of Bax and down-regulation of Bcl-2,which enhanced the apoptosis of GLUTag cells.Apocynin,the inhibitor of NADPH oxidase,prevented those responses and the effects caused by AGEs were abolished by inhibition of RAGE activity with siRNA.Conclusion AGEs positively regulate the exprcssion of NADPH oxidase-derived ROS and its down-steam signaling pathway p53/Bax by targeting RAGE,leading to the apoptosis of GLUTag cells.

Cannulated Screw is a common internal fixation for the treatment of femoral neck fractures. However, the traditional implantation method has disadvantages such as inaccuracy and large radiation exposure. Based on the anatomical characteristics of the femoral neck and geometric principles, we develop a novel guide device for cannulated screws insertion. The cadaver experiment showed that it can improve the accuracy of cannulated screws implantation, reduce puncture attempts and the radiation exposure of doctors and patients.

ObjectiveTo explore the correlation between skeletal muscle mass and metabolic syndrome （MS） disease risk among middle-aged and elderly community residents in Urumqi， and to provide a theoretical basis for understanding the relationship between skeletal muscle mass and MS among middle-aged and elderly community residents in China. MethodsA total of 1 438 community residents ≥ 50 years old were selected as the research subjects from July 2018 to January 2019 in Urumqi. They were selected from a multi-ethnic natural population cohort in Xinjiang. Data were collected through questionnaires， physical examination， bioelectrical impedance analysis （BIA）， laboratory tests， etc. Skeletal muscle mass was evaluated using the limb skeletal muscle mass index （SMI） corrected for body weight； MS was defined as it at least includes three of the following： abdominal obesity， hypertension， hyperglycemia， high triglycerides and low high-density lipoprotein cholesterol. SMI was divided into four quantile arrays of Q₁‒Q₄. Trend χ² test was applied to explore whether there was a correlation between SMI changes and MS. A multivariate logistic regression model was used to analyze whether there is a difference in the risk of MS between the higher SMI group （Q₂， Q₃， Q₄） and the reference group Q₁. ResultA total of 560 MS patients were detected in this study， with a prevalence rate of 38.94%. Among them， the prevalence rate of MS was 39.16% in males and 38.80% in females. The increase in male SMI grading level is not correlated with the prevalence of MS （trend P>0.05）； After adjusting for confounding factors （model 4）， the increase in SMI was still not related to the prevalence of MS （P_trend=0.995）. There was no statistical difference in the risk of MS between the lowest quartile group Q₁ and the highest quartile group Q₄ （OR=1.01， 95%CI： 0.69‒1.78）. The prevalence of MS in women gradually decreased with the increase of SMI grading level （P_trend<0.001）； After adjusting for confounding factors （model 4）， there was still a correlation between the increase of SMI and the prevalence of MS （P_trend=0.005）. With the lowest quartile of SMI Q₁ as the reference group， the risk of MS in Q₂ （OR=0.63， 95%CI： 0.40‒1.00）， Q₃ （OR=0.56， 95%CI： 0.34‒0.94）， Q₄ （OR=0.42， 95%CI： 0.23‒0.76） decreased. ConclusionAn increase in skeletal muscle mass may be beneficial for preventing MS， especially among middle-aged and elderly female residents. Considering the intensification of aging in China and the close relationship between MS and related comorbidities， managing skeletal muscle mass may contribute to potential MS prevention.
