Objective To determine the effects of sexual hormone therapy at varied doses on prevention of bone mineral loss in Chinese postmenopausal women. Methods From March 2002 to March 2003, 90 Chinese postmenopausal women were randomly divided into three groups, each given one of the following regiments for 12 months, estradiol valerate (EV) 1 mg plus medroxyprogesterone (MPA) 2 mg for group A (31 subjects), eonjngated estradiol (ethinylestradiol-3-cyclopentylether, CEE) 0.45 mg plus MPA 2 mg for group B (29 subjects) and livial 1.25 mg for group C (30 subjects), respectively. In addition, 400 mg of elemental calcium were given daily to all those women. Bone mineral density (BMD) of the 2nd to 4th lumbar vertebra (L2～4) and biochemical markers of bone turnover, urine N-telopeptide of type Ⅰ collagen/creatinine(NTX/Cr) and serum total alkaline phnsphatase (ALP), were measured before and after drug administration. Results After treatment for 12 months, BMD of the L2～4 increased significantly by 0.039 g/cm2(P<0.01) in group B, but not significantly in group A or group C (P<0.05). Increases in BMD of the L2～4 was more in group B than that in group A and group C, respectively (P < 0.05), but no significant difference in BMD increase between group A and group C was found (P >0.05). After treatment for 6 months, urine NTX/Cr reduced from the baseline for all the three groups (P < 0.05), but no significant difference among group A, group B and group C was found (P >0.05). After treatment for 12 months, serum ALP significantly reduced from the baseline for all the three groups (P <0.01), but no significant difference among group A, group B and group C wag found (P > 0.05). Conclusions Sexual hormone therapy at varied doses lower than regular one for 12 months was effective in preventing bone mineral less in postmenopausal women.

Methods Twenty-eight patients performed MSCT venography in inferior vena cava, including 2 cases with both indirect and direct venography, 10 cases with indirect venography, 20 cases with direct venography through unilateral or bilateral lower extremity venous injection. The image quality and enhancement degree of the inferior vena cava were compared in double-blind method. Results Of 10 cases with indirect venography of inferior vena cava, 1 case was failed due to mild enhancement in inferior vena cava. Image quality was good in 2 cases, poor in 7 cases, no excellent case. Of 20 cases with direct venography of inferior vena cava, the enhancement degree was scored 1, 2 degree in 16, 4 cases respectively and no case was scored 3 degree, the image quality was excellent, good in 16, 4 cases and no case was bad. The success rate was 100%. Conclusion The image quality of direct MSCT venography in inferior vena cava is better than that of indirect method.

ObjectiveTo investigate the difference in the outcomes in patients with acute anterior circulation stroke having achieved the Thrombolysis in Cerebral Infarction (TICI) 2b and TICI 3 recanalization after mechanical thrombectomy.MethodsThe patients with acute anterior circulation stroke having achieved successful recanalization after mechanical thrombectomy were enrolled retrospectively.They were divided into TICI 2b (almost complete recanalization) group and TICI 3 (complete recanalization) group.The good outcome was defined as the modified Rankin Scale score 0-2 at 3 months after onset.ResultsA total of 83 patients were enrolled in the study, including 38 patients (45.8%) with TICI 2b and 45 (54.2%) with TICI 3;49 (59.0%) had good outcome, and 34 (40.9%) had poor outcome.The good outcome rate in the TICI 3 group was significantly higher than that in the TICI 2b group (68.9% vs.47.4%;χ2=3.946, P=0.047).After adjusting for age, hypertension, diabetes, baseline systolic blood pressure, triglyceride, intravenous thrombolysis, and ASITN/SIR collateral grades, TICI 3 was an independent predictor for good outcome at 3 months after onset (odds ratio [OR] 3.759, 95% confidence interval [CI] 1.098-12.871;P=0.035), while the higher baseline National Institutes of Health Stroke Scale score (OR 0.820, 95% CI 0.715-0.941;P=0.005) and higher fasting glucose (OR 0.610, 95% CI 0.410-0.906;P=0.014) were the independent predictors for poor outcome at 3 months after onset.ConclusionsThere are difference in the outcomes in patients with successful recanalization in anterior circulation stroke treated with mechanical thrombectomy.The outcome is substantially better in TICI 3 than TICI 2b patients.

Swabbing samples were routinely collected from health care workers ( HCW) contacting newborns in Obstetrics Department of our hospital on every Wednesday during January to December 2015. Total 495 samples from nasal vestibule and 483 samples from hands of HCW were collected for bacterial culture.The carrying status of methicillin-resistant staphylococccus aureus ( MRSA) was analyzed.The results showed that the average carrying rate of MRSA in the nasal vestibule was 8.1%(40/495) and that in hands was 5.0(24/483)(χ2 =3.871, P<0.05).The MRSA detection rate of nasal vestibular samples in the second quarter was the highest [12.2%(17/139)], while that of hands samples was highest in the first quarter [ 15.3%( 15/98 ) ] . The study indicates that carrying rate of MRSA in health care workers contacting newborns of our hospital is high , and the training and monitoring should be strengthened among health workers to reduce the MRSA carrying rate .

Objective To compare the efficacies of 4 risk models (THRIVE[Totaled Health Risks in Vascular Events],MSS[Multicenter Stroke Survey],HIAT[Houston Intra-Arterial Therapy],and GRASPS[Glucose at presentation,Race,Age,Sex,Systolic blood pressure,Severity of stroke at presentation]) in predicting intracranial hemorrhage and poor outcomes in acute anterior circulation ischemic stroke after mechanical thrombectomy.Methods From May 2013 to March 2016,153 consecutive patients with acute anterior circulation vascular occlusion conducted mechanical thrombectomy within 6 hours after onset and admitted to the Departments of Neurology,Jinling Hospital,Nanjing University School of Medicine and Zhongshan Hospital,Xiamen University were enrolled prospectively.Logistic regression analysis and the area under the receiver operating characteristic (ROC) curve (AUC) were used to investigate the efficacies of 4 risk models (the THRIVE,MSS,HIAT,and GRASPS scores) for predicting intracerebral hemorrhage (including any intracranial hemorrhage events and symptomatic intracranial hemorrhage) and poor outcomes (including 90 d all-cause death and modified Rankin Scale[mRS] score≥3) in acute anterior circulation ischemic stroke after mechanical thrombectomy.Results The MSS score (AUC 0.639,95%CI 0.548-0.730,P=0.004) and GRASPS score (AUC 0.616,95%CI 0.525-0.706,P=0.017) could predict any intracranial hemorrhage events,but the predictive accuracy was low.They had the predictive value for death within 90 d after mechanical thrombectomy,and the GRASPS score (AUC 0.783,95%CI 0.706-0.860,P<0.001) had the moderate predictive accuracy,and the AUC of the other 3 models was all<0.7,the predictive accuracy was low.The models could predict the poor prognosis at 90 d (90 d mRS≥3).The AUCs of both the GRASPS score and THRIVE score were >0.7.The AUC of GRASPS score was the largest (AUC 0.782,95%CI 0.708-0.885,P<0.01).Both had moderate predictive accuracy.Conclusion The GRASPS score had a better clinical predictive value for all-cause death and poor prognosis within 90 d after mechanical thrombectomy.The THRIVE score had a better clinical predictive value for poor prognosis at 90 d.The 4 models predictive value for intracranial hemorrhage events after mechanical thrombectomy should be further examined.
