Survivin is the strongest member of the inhibitor of apoptosis protein(IAP)family. Smac is the second mitochondria-derived activator of cysteine proteases,which can promote apoptosis by combining with IAP. Abnormal expression of them is closely related with occurrence,development,treatment tolerance and prognosis of ovarian cancer. It is prompted that Survivin and Smac are expected to play important roles in the early diagnosis and targeted therapy of ovarian cancer.

This guideline was published by the American Institute of Ultrasound in Medicine,which has been developed to assist physicians performing sonographic studies of the brain in neonates and infants.Neurosonography should be performed only when there is a valid medical reason,and gain the necessary diagnostic information.Although it is not possible to detect every abnormality,adherence to the following guideline will maximize the detection of most abnormalities of the brain in neonates and infants that can be imaged with ultrasound.

Objective To investigate the clinical and pathological features of postmenopausal women with thickening endometrial. Methods Totally 187 patients with postmenopausal endometrial thickening by transvaginal B-ultrasound were divided into symptomatic group (n=104)and asymptomatic group (n=83).Their body mass index,age of menarche and menopause,history of menstruation and reproductive,application of estrogen,and hypertension and diabetes were collected.All the patients underwent hysteroscopy and biopsy procedures. Results There was no difference between two groups in body mass index [ (24.3 ± 3.2) kg/m2 vs.(23.3 ± 2.6) kg/m2,t =3.79,P =0.052]. The postmenopausal time of symptomatic patients in the group was shorter than the asymptomatic [ ( 14.6 ± 2.4) years vs.( 16.5 ± 2.9 ) years,t =4.12,P =0.039].The patients in the asymptomatic group were older than the patients in the symptomatic group [(68.1 ±4.8) years vs.(66.1± 5.5) years,F=3.89,P =0.046].The average endometrial thickness of patients in the asymptomatic group showed no difference compared with patients in the symptomatic group [(7.2 ±1.4) mm vs. (7.8 ± 2.0) mm,F=3.21,P=0.065]. There were 5 cases of endometrial adenocarcinoma,1 case of endometrial atypical hyperplasia,38 cases of endometrial polyp,25 cases of submucosal hysteromyoma,14 cases of proliferative phase endometrium in the asymptomatic group;while 8 cases of endometrial adenocarcinoma,1 case of endometrial stromal sarcoma,4 cases of endometrial serous papillary carcinoma,5 cases of endometrial atypical hyperplasia,47 cases of endometrial polyps,21 cases of submucosal hysteromyoma,2 cases of uterine empyema,8 cases of chronic inflammation of the endometrium, 8 cases of proliferative phase endometrium in the symptomatic group,respectively. Conclusions Most of endometrial thickness in postmenopausal women are benign lesions, mainly including endometrial polyps and submucous myoma, but endometrial cancer accounts for a certain percentage. Hysteroscopy is minimally invasive,safe and with specificity for the diagnosis and treatment of endometrial lesions.

ObjectiveTo compare the clinical disease activity index (CDAI) and simplified disease activity index(SDAI) as well as disease activity score 28(DAS28) by assessing the activity of rheumatoid arthritis (RA) and to explore which one is better.MethodsTwo hundred RA patients were enrolled.Swelling joint counts (SJC),tenderness joint counts(TJC ),patient's and doctor's global assessment of disease activity based on visual analogue scale(PGA,PhGA),health assessment questionnaire(HAQ) were recorded and the erythrocyte sedimentation rate(ESR),C reaction protein (CRP) of each patient were tested.DAS28,CDAI,SDAI of all patients were calculated for all patients.Statistical analysiswas carried out by Pearson correlation for the association between DAS28 and the above parameters,as well as CDAI,and SDAI.We created 4 patient groups based on DAS28,CDAI and SDAI ranks and used kappa statistics to assess the level of overall agreement of different disease activity categories between any of the two indices above for individual patients.We assessed the discriminating validity using receiver operating characteristic(ROC) curve analysis to compare the ability of the CDAI and SDAI to discriminate betwecn patients with remission, low and moderate,high disease activity.ResultsOf all the patients,CDAI(17.2±11.1) and SDA[(19.1±11.6) were correlated with DAS28 (4.3±1.5),the correlation coefficients were 0.876,0.861 (P＜0.05) respectively.CDAI and SDAI were correlated with HAQ (0.6±0.7),as well as DAS28.The correlation coefficients were 0.522,0.523,and 0.482(P＜0.05).The Kappa of CDAI and SDAI was 0.777.The Kappa of CDAI and DAS28,SDAI and DAS28 were 0.482,0.394.The areas under ROC of CDAI and SDAI were 0.906,0.888 if DAS28 was used as the gold standard.ConclusionCDAI and SDAI as well as DAS28 can be used to assess the activity of RA and both are better correlated with HAQ than DAS28.Though there is no CRP in CDAI when compared with SDAI,CDAI has very goodoverall agreement with SDAI and the overall agreement of CDAI and DAS28 is better than SDAI and DAS28.In addition, CDAI is better in discriminating between patients with remission/low and moderate/high disease activity.So,CDAI is a simple,convenient,accurate,quick assessment tool and is suitable for daily application.

Objective To explore the clinical effect of arthrolysis and a hinged external fixator for treatment of posttraumatic elbow stiffness.Methods From April 2007 to April 2012,26 cases of posttraumatic elbow stiffness patients were treated with arthr o lysis and a hinged external fixator after operation,and the effect was observed.Results After operation,26 patients were followed up for 15(8-24) months,the ranges of elbow joint motion increased from (42 ± 17) ° to (119 ± 17) ° after operation.There was significant difference (t =152.85,P＜ 0.05).The MEPS scores increased from (36 ± 13) points to (82 ± 14) points after operation,15 cases were excellent,5 cases were good,3 cases were fair and 3 cases were poor,the rate of excellent and good cases was 76.9％ (20/26).Twenty-three cases (88.5％,23/26)elbow function improved.Postoperative infective complication occurred in 1 case,postponed incision healing occurred in 1 case and 1 patient had cubital nerve paralysis,the symptom disappeared after 3 months and the patient showed no instability in elbow joint.Conclusion Arthrolysis and a hinged external fixator can deep stabe the elbow and its specific position,allowing early rehabilitation to promote functional recover of the elbow.

Objective:To establish a Crownpak CR( +)-HPLC method for the determination of the content and related substance of valacyclovir hydrochloride dispersible tablets. Methods: A Crownpak CR( +) [4. 0 mm × 150 mm,5 μm,DAICEL CROWNPAK CR( +)] column was used,and the mobile phase was 0. 1% perchloric acid in water. The flow rate was 0. 75 ml·min-1 and the de-tection wavelength was 255 nm. Results: A good linear range of valacyclovir hydrochloride was 11. 25-180. 00 μg · ml-1 ( r =1. 000 0), and the average recovery was 99. 0%(RSD=0. 8%, n=9). A good linear range of alacyclovir was 0. 2-50μg·ml-1(r=1. 000 0), and the average recovery was 99. 3%(RSD=0. 6%, n=9). The content of the tablets from two pharmaceutical companies was 92. 7% and 97. 4%, respectively, that of acyclovir calculated by an external standard method was 0. 5% and 0. 4%, respectively, and that of D-valacyclovir calculated by a self-control method was 0. 9%.

Background:In recent years,the incidence and mortality of colorectal carcinoma have been increasing rapidly. Diagnosing and treating cancer at gene level have become a new effective approach. Aims:To investigate the expression of S-phase kinase-associated protein 2(Skp2)and its relationship with vascular endothelial growth factor(VEGF)and tumor microvessel density(MVD)in colorectal carcinoma. Methods:Thirty-five colorectal carcinoma patients from March 2014 to March 2015 at People’s Hospital of Hubei University of Medicine were enrolled. Fifteen para-cancerous tissue samples were served as controls. The expressions of Skp2,VEGF and MVD value were determined by immunohistochemical SP, and their relationships with clinicopathological characteristics were analyzed. Results:The expression of Skp2 in colorectal carcinoma was significantly higher than that in para-cancerous tissue( P = 0. 000),and was correlated with tumor differentiation and lymph node metastasis(P < 0. 05),but not with gender,age and TNM stage(P > 0. 05). Expression of VEGF and MVD value were significantly higher than those in para-cancerous tissue(P = 0. 019,P = 0. 002),and were correlated with lymph node metastasis and TNM stage(P < 0. 05). Expression of Skp2 was positively correlated with the expression of VEGF and MVD value in colorectal carcinoma( r = 0. 569,P = 0. 000;r = 0. 481,P = 0. 017 ). Conclusions:The abnormal high expression of Skp2 is involved in the angiogenesis of colorectal carcinoma. Skp2,VEGF expressions and MVD value may be served as important markers for malignancy degree of colorectal carcinoma.

Rheumatoid diseases (RD) are a group of diseases affecting bones,joints,and the surrounding soft tissues,such as muscle,synovial membrane,tendons,fascia,nervus.The etiology and pathogenesis are complicated.Since most RD are systemic diseases,traditional imaging techniques have limited value for the diagnosis and treatment monitoring of RD.18F-FDG PET/CT can display morphologic and metabolic information simultaneously,and is considered as a potential tool for the diagnosis of RD.This review summarizes the application of 18F-FDG PET/CT in RD,such as systemic vasculitis,relapsing polychondritis and rheumatoid arthritis.
