Objective To study the different biomechanics surgical effects of posterolateral fusion , the transverse fusion and the interbody fusion. Method Scan CT was followed with preprocess of images. The Mimics , HyperMesh and Geomagic Studio Reverse engineering softwares were used to establish the modles of lumbar fusion , then the finite element computation was conducted by using the Abaqus finite element software. Result The EF of each lumbar modle was established , the EF of the interbody fusionwas rised evidently. After the fusion , the stress of the adjacent lumbar were also rised, among them the stress of the upper adjacent segment in tnterbody fusion was the most in extension and rotation , with statistical significance ( P < 0 . 05 ) . In the antexion the stress of the transverse fusion was the most, and the new type of posterolateral fusion least, three of them all hadstatistical significance (P<0.05). In the lateral flexion, they had no statistical significance (P>0.05). About the under adjacent sengment, in the extension and antexion, the stress of the interbody fusion was the most, and the new type of posterolateral fusion was the least, the three of them all haved statistical significance (P<0.05, respectively). In the rotation and lateral flexion, with no statistical significance (P>0.05). Conclusion After the fusion, the EF of the lumbar and the stress of the lumbar disc are all established, the interbody fusion is most, while the others are lower.

Objective To analyze TORCH infection situation in 6 027 cases of pregnant women,puerperae and neonates.Methods The TORCH IgM and IgG was detected by using ELISA for 6 027 cases of pregnant women,puerperae and neonates,and the positive rates of the antibodies to variant TORCH pathogens were analyzed.Results The positive rates of HSVⅠ-IgM,HSVⅡ-IgM,RV-IgM,TOXO-IgM and CMV-IgM were 0.02%,0.02%,0.12%,0.12% and 0.20% respectively.The positive rates of HSVⅠ-IgG,HSVⅡ-IgM,RV-IgM,TOXO-IgM,and CMV-IgM were 63.32%,13.31%,52.83%,12.68% and 58.57% respective-ly.Positive rate of CMV-IgM in neonates was higher than that in pregnant women,the difference was statistically significant(P <0.05).There were totally 28 cases of neonataes detected with acute CMV infection.Conclusion TORCH screening in pregnant women,puerperae and neonates helps the detection of infection disease in perinatal period.

Objective To observe the effect of low molecular weight heparin calcium combined with astraga-lus injection in the treatment of diabetic nephropathy.Methods From January 2013 to December 2014,78 patients with stage III diabetic nephropathy in our hospital were enrolled into the study.They were randomly divided into con-trol group(41 cases) and treatment group(37 cases).The control group received general therapy,such as low protein diets,compound alpha keto acid,insulin,irbesartan,simvastatin.The treatment group was treated with low molecular weight heparin calcium and astragalus injection on the basis of general therapy.The changes of urinary albumin and 24 hours urinary protein after treatment in the two groups were observed.Results After treatment,the negative rate of urinary micro albumin in the treatment group ( 75.68%) was significantly higher than that of the control group (29.27%)(χ2 =16.765,P<0.01).24 hour urinary protein of the treatment group[(176.2 ±82.3)mg/24h]was significantly lower than that of the control group[(223.8 ±87.8)mg/24h](t=2.471,P<0.05).Conclusion Low molecular weight heparin calcium combined with astragalus injection can reduce the proteinuria of diabetic nephropa-thy,it is an effective intervention therapy for early diabetic nephropathy.

Objective To investigate the clinical characteristics of pre-malignant and malignant polyps in postmenopausal patients and to evaluate the diagnositic value of hysteroscopy in this disease. Methods From June 2005 to October 2014, 403 postmenopausal patients with polyps were treated in the Gynecologic Minimally Invasive Center, Beijing Obstetrics and Gynecology Hospital. There were 27 patients including 22 patients with pre-malignant and 5 patients with malignant polyps. All malignant lesions were endometrioid adenocarcinoma. The clinical data were retrospectively analyzed. Based on pathology, the diagnostic value of hysteroscopy was evaluated. Results (1) Clinical characteristics: there were 27 cases with pre-malignant and malignant polyps (group 1) and 376 cases with benign polyps (group 2). Compared the two groups, the average age was (60 ± 8) vs (58 ± 6) years old, the period of menopause was (9.8 ± 8.1) vs (8.3 ± 6.9) years. Thirteen cases (48.1%, 13/27) in group 1 and 159 cases (42.3%, 159/376) in group 2 had clinical symptoms including postmenopausal bleeding and vaginal discharge. Twelve cases (44.4%, 12/27) in group 1 and 140 cases (37.2%, 140/376) in group 2 were with hypertension. Five cases (18.5%, 5/27) in group 1 and 43 cases (11.4%, 43/376) in group 2 were with diabetes. The measures above were no significant differences(P>0.05)(2) Ultrasound features:the average thick of endometrium in group 1 and group 2 were respectively (1.3±0.7) and (0.8±0.4) cm, which had statistical significance (t=4.98, P=0.001). (3) Hysteroscopic diagnosis:the average diameters of polyp in group 1 and group 2 were respectively (2.4 ± 1.0) and (1.6 ± 1.0) cm, which had statistical significance (t=2.93, P=0.004). Six cases in group 1 were diagnosed by hysteroscopy including 4 cases of malignant polyp and 2 cases of pre-malignant polyp. The sensitivity, specificity, positive predictive value, negative predictive value and the accuracy were 22.2%(6/27), 100.0%(376/376), 100.0%(6/6), 94.7%(376/397) and 94.8%(382/403), respectively. Conclusions Pre-malignant and malignant endometrial polyps are more common in the subjects with the larger diameters and the thicker endometrium. All polyps should be under complete resection by hysteroscopy and through pathology examination.

Objective To investigate serum cardiac troponin T(cTnT) and C-reactive protein (CRP) levels and assess the prognostic values of cTnT and CRP of mortality and cardiovascular events in maintenance hemodialysis (MHD) patients. Methods One hundred and six MHD patients were enrolled in this study. Serum cTnT, CRP, creatinine, albumin were measured in pre-hemodialysis at the beginning of the study. The mortality and cardiovascular events were recorded during the period of follow up. Results At the initiation of the study,28 patients (26.42%) were recorded with positive cTnT level, 32(30.19%) with positive CRP and 16 (15.09%) with positive cTnT and CRP. Logistic regression analysis showed a significant correlation between serum cTnT and serum CRP and Scr. Patients with positive cTnT and CRP levels had higher mortality and more cardiovascular events than those with negative levels. Kaplan-Meier survival analysis showed a significant difference between patients with normal and abnormal cTnT and CRP levels. Conclusions Some MHD patients have elevated serum cTnT level. Serum cTnT level is correlated with serum CRP and creatinine level. Patients with positive cTnT and CRP levels have higher mortality and more cardiovascular events than those with negative levels.
