Menarche and menopause are two important physiological periods that denote the beginning and the end of normal reproductive life.Studies have suggested that ages at menarche and menopause are important biological markers,and are also predictors of several chronic diseases.We published one manuscript in J Clin Endocrinol Metab titled Associations between age at menarche and menopause with cardiovascular disease,diabetes,and osteoporosis in Chinese women,which suggested that ages at menarche and menopause are not associated with diabetes,delayed menarche and menopause are associated with decreased risk of cardiovascular disease risk and early menopause with high risk of osteoporosis.

Objective To Analyze the distribution characteristics of Hyperthyroidism's syndrome and the relationship between symptoms and thyroid hormones. Methods The TCM syndromes of a total of 78 patients with hyperthyroidism were differentiated. The relationship between syndrome and general condition of patients (gender and age, etc.) were analyzed;correlation between symptoms and thyroid hormones were also studied. Results Of all 78 patients, patients with yin deficiency and hyperactive yang accounted for 43.6%; patients with internal disturbance of phlegm-fire accounted for 30.8 %; and patients with hypteracitivity of heart-fire and liver-fire accounted for 25.6%. The severity of all the symptoms showed positive correlation with hyroid hormones (the value of r is positive, P＜0.05); and no linear relationship with TSH (P＞0.05).Conclusion The syndrome of yin deficiency and hyperactive yangI was the most common syndrome type. Thyroid hormones had direct proportion with the severity of syndrome.

Objective To evaluate the primary application of drug eluting stent for treatment of vertebral stenosis. Methods One vertebral original stenosis was treated by CYPHER TM stent and the relative papers were reviewed. Results A male of 53 years old with paroxysmal vertigo and left hemiplegy revealed nothing abnormal by magnetic resonance imaging (Diffusion Weighted Imaging). But the DSC found his right vertebral origin 4.6 mm long stenosis (more than 90%), the remote artery was 2.6 mm in diameter, and angiography in the right vertebral origin showed right post inferior cerebellar artery (PICA) insufficiently filled and no development of basilar artery. When angiography in the left vertebral, there was no fill in the right PICA. The restenosis rate after vertebral origin stent posting was as high as 43.3%, but drug eluting stent can prevent restenosis. After preparation, a 2.75 mm?13 mm balloon-expandable Cypher stent was posted in on 2004-06-07. Angiography showed the stenosis disappeared, right PICA sufficiently filled, and basilar artery appeared. Antiplatelet agents were used afterwards. There was no attack of vertigo and hemiplegy in the followed-up month. Conclusions The success of using drug eluting stent in verebral artery offers a new choice on preventing ischemia stroke, the long time followed-up is necessary.

Objective To explore the MRI characterisitics of primary dilated cardiomyopathy and isolated left ventricular non-compaction.Methods The patients who were diagnosed as primary dilated cardiomyopathy (n=18) and isolated left ventricular non-compaction (n=10) were enrolled,and the MRI was performed.The thickness of non-compaction myocardium (NC),compaction myocardium (C) in end-diastole,the feature of movement of myocardium,the number of non-compaction segment,the fraction shortening of non-compaction and the distribution were compared.Results Totally 823 segments were analyzed in primary dilated cardiomyopathy,in which 124 segments were non-compaction myocardium;397 segments were analyzed in isolated left ventricular non-compaction,in which 115 segments were non-compaction myocardium.The NC,NC/C,NC/(NC+C),and the fraction shortening of the isolated left ventricular non-compaction patients were higher than those of primary dilated cardiomyopathy patients (all P＜0.05).The features of distribution showed that the apical segment was mostly involved,and the basal segment was less involved or hardly involved.The anterior and lateral segments were more involved in the free wall,the septal was less involved.Conclusion The MRI characteristics of primary dilated cardiomyopathy and isolated left ventricular non-compaction are different,especially in the distribution,non compacted segments,NC and NC/C,which is important for diagnosis and differential diagnosis of the two diseases.

Objective To investigate the impact of simvastatin on blood lipid and the incidence of atrial fibrillation and ischemic-related events in patients with acute myocardial infarction accompanied by paroxysmal atrial fibrillation. Methods One hundred and three patients with acute myocardial infarction and paroxysmal atrial fibrillation were selected as subjects, and were divided into a simvastatin group and a control group. Forty-five patients were in the simvastatin group, who took simvastatin 20mg/d orally for 18 months; fifty-eight patients were in the control group, and received conventional therapy except for statins. All patients were followed up for 18months. The level of blood lipid, recurrence rate of paroxysmal atrial fibrillation, incidence rate of persistent or permanent atrial lipids did not change significantly in the control group (P＞0.05); concentrations of total cholesterol (TC) and low density lipoprotein five patients during 18 months follow-up in the simvastatin group (11.1%), whereas it occurred in 14 patients of the control group(24.1%, P＜0.05); the occurrence rate of persistent or permanent atrial fibrillation in the simvastatin group was 4.4%, which was lower than (6.6%), two rehospitalizations for deterioration of coronary heart diseases (4.4%), three cardiac deaths (6.6%), and one cerebral stroke (2.2%), which was lower evidently than in the control group (41.4%, P＜0.05). Conclusions Simvastatin can not only decrease the levels of serum TC and LDL-C but also prevent the occurrence of atrial fibrillation and ischemic-related events.

Objective The main purpose is to investigate the status of brucellosis infection in high-risk areas of Urumqi and population characteristics,and to provide a basis for prevention of brucellosis.Methods In Urumqi City,Dabancheng District,Gaoxin District,Midong,Zone and Urumqi County were selected as survey sites;according to pastoral,agro-pastoral and agricultural,all towns in each survey site were classified into three categories;150 to 200 residents in each township were selected as subjects.Basic demographic information was collected,and blood samples were collected for serological detection.rose bengal plate agglutination test (RBPT) was used for preliminary screening,RBPT positive persons were further confirmed by standard tube agglutination test (SAT).Different regions,gender,age,occupation,exposure difference and brucellosis infection rates were studied.x2 test was used to compare rates.Results The infection rate was 5.42％ (29/535).Furthermore,the infection rate ofthe Dabancheng District [10.34％ (12/116)] was higher than those of Gaoxin District [2.94％ (3/102)] and Urumqi County [2.58％ (4/155),x2 =4.643,7.199,all P ＜ 0.05],the differences were statistically significant (x2 =9.327,P ＜0.05).Besides,infection rate of the average exposure occupation [8.33％ (24/288)] was higher than those of low exposure occupation [0(0/61)] and high exposure occupation [2.72％ (5/184),x2 =5.459,6.140,all P ＜ 0.05].The differences were statistically significant (x2 =10.846,P ＜ 0.05).The differences of infection rates in ages and nations showed no statistical significance (x2 =2.396,4.639,all P ＞ 0.05).Conclusions High risk areas of brucellosis are still exist in Urumqi.Health education should be strengthened in the future,in order to enhance residents' seff-protection awareness in exposed population.

Objective To investigate the effect of propofol on autophagy in SD rat heart during myocar-dial ischemia-reperfusion (I/R) injury. Methods Twenty-one male SD rats were randomly divided into three groups as follows (n = 7): the sham operation group, in which rats underwent sham operation without tightening of the coronary artery sutures; the myocardial ischemia-reperfusion group , in which rats were induced by occlud-ing the left anterior descending coronary artery for 30 min , followed by 120 min reperfusion and 0.9% NaCl in-fusion at 3 mL/(kg·h) at 10 min before occluding the left anterior descending coronary artery; the myocardial ischemia- reperfusion- propofol group, in which rats underwent I/R and propofol infusion at 6 mg/(kg·h) at 10 min before occluding the left anterior descending coronary artery. Before tightening of the coronary artery, at 30 min post-tightening of the coronary artery and at 120 min post-reperfusion, HR、 LVSP and ± dp/dtmax of rats were recordedin each group. Atter 120 min post-reperfusion, the serum concentrations of cTnT was measured. The in-jured cardiac tissue was collected to investigate the ultrastructure change under the TEM and to determine the levels of mTOR and p-mTOR. Results No signifcant differences in HR, LVSP and ± dp/dtmax before tighten-ing of the coronary artery. But, at 30 min post- tightening of the coronary artery, compared with groupⅠ, the HR, LVSP and ±dp/dtmax were significantly decresed in groupⅡ and Ⅲ(P < 0.05). Then, at 2 h post-reper-fusion, compared with groupⅠ, the HR, LVSP, ±dp/dtmax and the level of p-mTOR were significantly de-creased, but the serum concentration of cTnT was significantly increased in groupⅡ(P < 0.05); but, compared with groupⅡ, the HR, LVSP, ± dp/dtmax and the level of p-mTOR were significantly increased, the serum concentration of cTnT and the level of mTOR were significantly decreased in group Ⅲ(P < 0.05). Conclusions These data suggest that propofol could heighten the level of p-mTOR, and attenuate the expression of mTOR dur-ing the myocardial ischemia-reperfusion injury in SD rats.

Objective To elucidate the role of the Wnt/-catenin signaling pathway in regulating the phenotypic transformation of aortic valvular myofibroblasts to osteoblast-like cells.Methods Cultured primary valvular myofibroblastes isolated from porcine aortic valve leaflets were treated with oxidized low-density lipoprotein (ox-LDL) for different lengths of time:24 h,48 h and 72 h.The Wnt signaling pathway inhibitor Dickkopf-1 (DDK-1) was co-incubated with ox-LDL for 72 h.After cells harvest,the expression of myofibroblastic or osteoblast-like phenotype related markers,a-smooth muscle actin (α-SMA),bone morphogenetic protein 2 (BMP2),alkaline phosphatase (ALP) and corebinding factora-1 (Cbfα 1),was detected by Western blotting.The expression and sub cellular localization of β3-catenin was assessed by immunocytochemistry.Changes of the Wnt/β-catenin signaling pathway and the transformation of aortic valvular myofibroblast to osteoblast-like cells were monitored.Results BMP2,ALP and Cbfa 1 protein expression was not or barely detectable in the control group.However,after ox-LDL treatment,the expression of α SMA,BMP2,ALP and Cbfa 1 increased significantly (each P＜0.01) in a time-dependent manner (each P＜0.05).Besides,ox-LDL was also able to up-regulate the protein expression of β-catenin in a time-dependent manner (P＜0.05) and promoted its nuclear translocation.After DKK-1 treatment,the protein expression of β3 catenin and osteogenesis related markers was down regulated (P＜0.05).Conclusions The Wnt/β-catenin signaling pathway may play a crucial role in regulating the transformation of aortic valvular myofibroblasts to an osteoblast like phenotype.

Objective To investigate the time and implant selection in conversion from external fixation to internal fixation of tibial shaft fracture.Methods Data of 57 cases of tibial shaft fracture fixed externally followed by internal fixation from February 2003 to February 2012 were analyzed.Internal fixation (intramedullary nails or plates) initiated within 2 weeks (Group A,n =.35) and over 2 weeks (Group B,n =22) were compared in outcomes.Results One infection (3％) and four poor bone healing (11％) were observed in Group A.Five infections (23％) and three poor bone healing (14％) occurred in Group B.For intramedullary nail fixation,no infection was observed in Group A but infection rate of44％ was found in Group B.For plate internal fixation,infection rate was 8％ for both groups.Conclusions The conversion from internal fixation to internal fixation had better start within 2 weeks,with better resuhs,lower rate of infection and safer in comparison with that over 2 weeks.In addition,pin-tract infection is the high risk factor for infection after the conversion of the fixation.
