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 compare the test bolus technique with the bolus tracking technique for dual-energy CT pulmonary angiography in patients suspected of pulmonary embolism (PE).Methods A total of 60 patients were randomized into 2 groups:bolus tracking technique group (group B,n =30) and test bolus technique group (group T,n =30).A standard dual-energy CT pulmonary angiography (CTPA)was performed after injection of 60 ml contrast medium followed by 35ml saline chaser at a speed of 4 mL/s.Attenuation profiles of different vascular segments (the subclavian vein,superior vena cava,left atrium,pulmonary trunk,S1 and S10 pulmonary artery) and enhancement value of lung parenchyma were measured to evaluate the timing techniques.The overall image quality of CTPA and pulmonary perfusion were analyzed by two radiologists.SPSS 19.0,Student t test,ANOVA test,Chi-Square test,Mann-Whitney U test and Kappa test were used for the statistic analysis.Results The attenuation of the subclavian vein [(1042 ± 639),(2200 ± 724) HU,F =43.196,P =0.001],superior vena cava [(529 ± 237),(904 ± 329)HU,F=25.654,P=0.001],pulmonary trunk [(325 ±112),(383±69)HU,F=5.94,P=0.018],S1 pulmonary artery [(320 ± 118),(385 ±73) HU,F =6.549,P =0.013],S10 pulmonary artery [(307 ± 78),(360 ± 82) HU,F =6.658,P =0.012] in group B were lower than those in group T,while the attenuation of the left atrium in group B was higher than that in group T [(270 ± 53),(219 ± 57)HU,F=12.823,P =0.001].The percentage of pulmonary arteries exceeding optimal attenuation (＞ 250 HU) in groups B was lower than that in group T [n =21 (70.0％),n =29 (96.7％),x2 =5.88,P ＜ 0.05].The enhancement value of pulmonary parenchyma in group B was lower than that in group T (the right lung (29±8)vs(34±8) HU,t=-2.401,P=0.020; the left lung (30±7)vs(36±9)HU,t=-2.493,P=0.016; total (30 ±7)vs(35 ±8) HU,t =-2.495,P =0.016).The image quality of CTPA in group B was poorer than that in group T (U =619.5,P ＜ 0.05,Kappa =0.708),while the artifacts of lung perfusion image in group B was less than that in group T (U =162.5,P ＜ 0.05,Kappa =0.796).Conclusion The test bolus technique has a better image quality of CT pulmonary angiography and a higher lung perfusion blood volume compared with the bolus tracking technique by using 60 ml contrast medium and 35ml saline.

Objective To investigate the antitumour effects of transfected gut-enriched Krüppellike factor(GKLF) on human gastric carcinoma cell line SGC-7901 in vitro and in vivo. Methods The expression of GKLF mRNA and protein in human gastric carcinoma cell line SGC-7901 were detected before and after transfection by real-time fluorescence quantitative PCR and Western blot,respectively. Proliferation and invasion in SGC-7901 were measured respectively by MTT assay, flow cytometry, colony formation assay and cell invasion assay after transfected with GKLF. The growth of xenograft was observed, the microvessel density(MVD) of xenograft tissue was determined by immunohistochemistry. Results The GKLF mRNA and protein in SGC-7901 were overexpressed after transfected with GKLF(P＜0.05). The proliferative speed of SGC7901-pcDNA3.1-GKLF group was markedly lower than that of SGC-7901 and SGC7901-pcDNA3.1 groups (P＜0.05). Transfected with GKLF caused part of the G0/G1 arrest, decreased clone formation rate and the invasion ability (P＜0.05). The growth speed of xenograft in SGC7901-pcDNA3.1-GKLF group was lower, the weight and MVD of xenograft tissue in SGC7901-pcDNA3. 1-GKLF group were less (P＜ 0. 05).Conclusion Transfected with GKLF maysuppress proliferation and invasion in human gastric carcinoma cell line SGC-7901, inhibit the growth and the angiogenesis of xenograft in nude mice.

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.

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 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.
