Objective To investigate the clinical effect of McDonald cervical cerclage and the affecting factors. Methods Between January 2002 to December 2013 in Peking University First Hospital we performed McDonald cervical cerclage for 116 single pregnant women. They were defined as the successful group who deliveried the live babies after 28 weeks after the cerclage and the failure group who deliveried in the second trimester. According to the surgical indications they were divided into preventive cerclage group and therapeutic cerclage group. Then we analyzed the curative effect and the affecting factors in the groups. Results (1) In the 116 cases, 12 cases (10.3%) failed, and 104 cases (89.7%) succeeded. In the successful group, 37 cases (35.6%,37/104) deliveried pretermly and 67 cases (64.4%) deliveried termly. And there were 56 cases of vaginal delivery (53.8%), and 48 cases (46.2%) of cesarean section. (2) Among the 116 cases, 48 cases (41.4%) were included in prophylactic cerclage group, the gestational age was (16.3± 2.2) weeks, 68 (58.6%) cases were included in therapeutic group, the gestational age was (24.0±2.2) weeks. The operation time was (22±9) minutes in preventive group and (24±13) minutes in therapeutic group,there was no statistical difference between the two groups (P>0.05). Live-birth rate between preventive cerclage group and therapeutic cerclage group was no statistically significant difference (P>0.05). The term birth rate (72.9%, 35/48) in preventive group was higher than that in therapeutic group (47.1%, 32/68), the difference was statistically significant (P<0.01). Neonatal hospitalization rate was lower in preventive group (14.6%, 7/48) than therapeutic group (36.8%, 25/68) , the difference was statistically significant (P< 0.01). (3) In the failure group placental pathology was examed in 7 cases. The placental tissue showed a large number of neutrophils infiltrating in 6 cases (6/7). In the successful group, 27 pregnant women deliveried between 28 to 33+6 weeks (26.0%,27/104), 10 pregnant women deliveried between 34 to 36+6 weeks 10 cases (9.6%, 10/104), 67 cases deliveried after 37 weeks (64.4%, 67/104). A lot of factors including maternal age, the previous cervix operation history, perioperative application of progesterone, operation time and preoperative invasive procedure were compared between the successful group and the failure group. Only maternal age and preoperative invasive proedcure were statistically significant (P<0.05) and the others had no statistical significance (P>0.05). (4) There were 68 cases in the therapeutic group, 7 cases failed, and 61 cases succeeded;the preoperative cervical os in failure group [ (21 ± 20) mm] was wider than that in successful group [(14±5) mm], the difference was statistically significant (P<0.05);and preoperative vaginal ultrasound measurement of cervical canal length were (18 ± 8) mm versus (19 ± 10) mm, there was no statistically significant difference (P>0.05). Conclusions The McDonald cervical cerclage for cervical incompetence is a simple, safe and high successful rate of intervention measures. The term labor rate of prophylactic cervical cerclage was higher than that of the therapeutic cerclage. Older maternal age and preoperative invasive procedure may be the risk factors for cerclage. The infection may play an important factor leading to the failure of McDonald cervical cerclage.

Objective To study of the imaging diagnosis and differential diagnosis of cystitis glandularis. Methods The clinical data and imaging findings of 8 cases with cystitis glandularis proved by pathology were retrospectively analyzed with literaures re-view. Results The lesions on images appeared as nodular mass in 4 cases, diffuse in 2 cases and mixed type in 2 cases,1 case with cystic degeneration. The lesions in 2 cases obviously reduced in size after treatment. The CT value of the lesions post contrast-en-hanced scan averagely increased up to 15.8 HU compared with that of plain scan. The lesions were localized in 6 cases and diffuse in 2 cases. Conclusion cystitis galandularis has some imaging characteristics, but the final diagnosis is depended on pathology.

This paper is to investigate the effect of ischemic preconditioning on cardiac function in the hyperlipidemic rats.The alterations of LVSP,(d p /d t ) max , GSH Px, SOD and MDA were measured in ischemia/reperfusion group, ischemic preconditoning group and control group with in vitro myocardial ischemic precondioning model. The level of LVSP, (d p /d t ) max , GSH Px and SOD was significantly higher in the preconditoning group than that in the ischemia/reperfusion group, and these values were close to those in the control group. The area of contraction component in P cycle was higher and the amount of MDA was lower, whereas the level of LVSP, (d p /d t ) max declined significantly in ischemia/reperfusion group.It is suggested that ischemic preconditoning in hyperlipidemic rats can reduce cardiac functional impairment due to ischemia/reperfusion injury, and may have myocardial protective effects.

OBJECTIVE:To establish a new semi-automatic drug dispensing mode,with proper cost,which falls in between full-automatic drug dispensing mode and manual drug dispensing mode,good work efficiency,standard and simple operation meth-od and meets national laws and regulations. METHODS:A semi-automatic drug dispensing system was designed,in which the in-formation in the drug dispensing sheet could be automatically printed on the drug bag,and automatic bagging,packaging and deliv-ery of drugs were realized. Such drug dispensing system included hardware(mechanical structures such as drug turntable and drug funnel,transmission device,etc.)and software control systems(the program of interface with hospital information system,micro control unit software,computer software,etc.). Through commissioning,formal operation and statistics,based on 18 oral drug dis-pensing sheets with the same contents,calculated the time of drug dispensing and the number of drug dispensing errors by 3 phar-macists respectively in manual drug bag dispensing mode and semi-automatic drug dispensing mode,to evaluate the effect of the semi-automatic drug dispensing system. RESULTS:From commissioning in May 2012 to formal operation in September 2012,the system operated normally and utility model patents were obtained. In the two modes,the total time of drug dispensing was 481 and 397 min (t=6.82,P<0.001),the numbers of drug dispensing errors were 25 and 7 (χ2=9.353 8,P=0.002 2),respectively. There was statistical significance. CONCLUSIONS:The semi-automatic drug dispensing system has higher efficiency and less num-ber of drug dispensing errors compared with manual drug bag dispensing mode and lower cost compared to full-automatic drug dis-pensing system. It deserves promotion.

OBJECTIVE: To investigate the involvement of ephrinB2 in periodontal tissue remodeling in compression areas during orthodontic tooth movement and the effects of compressive force on EphB4 and ephrinB2 expression in osteoblasts and osteoclasts. METHODS: A rat model of experimental tooth movement was established to examine the histological changes and the localization of ephrinB2 in compressed periodontal tissues during experimental tooth movement. RAW264.7 cells and ST2 cells, used as precursor cells of osteoclasts and osteoblasts, respectively, were subjected to compressive force in vitro. The gene expression of EphB4 and ephrinB2, as well as bone-associated factors including Runx2, Sp7, NFATc1, and calcitonin receptor, were examined by quantitative real-time polymerase chain reaction (PCR). RESULTS: Histological examination of the compression areas of alveolar bone from experimental rats showed that osteoclastogenic activities were promoted while osteogenic activities were inhibited. Immunohistochemistry revealed that ephrinB2 was strongly expressed in osteoclasts in these areas. Quantitative real-time PCR showed that mRNA levels of NFATc1, calcitonin receptor, and ephrinB2 were increased significantly in compressed RAW264.7 cells, and the expression of ephrinB2, EphB4, Sp7, and Runx2 was decreased significantly in compressed ST2 cells. CONCLUSIONS: Our results indicate that compressive force can regulate EphB4 and ephrinB2 expression in osteoblasts and osteoclasts, which might contribute to alveolar bone resorption in compression areas during orthodontic tooth movement.

Cryptotanshinone (CPT) is a natural compound isolated from traditional Chinese medicine Salvia miltiorrhiza Bunge. In the present study, the regulatory effect and potential mechanisms of CPT on tumor necrosis factor alpha (TNF-α) induced lectin-like receptor for oxidized low density lipoprotein (LOX-1) were investigated. Human umbilical vein endothelial cells (HUVECs) were cultured and the effect of TNF-α on LOX-1 expression at mRNA and protein levels was determined by Real-time PCR and Western blotting respectively. The formation of intracellular ROS was determined with fluorescence probe CM-DCFH2-DA. The endothelial ox-LDL uptake was evaluated with DiI-ox-LDL. The effect of CPT on LOX-1 expression was also evaluated with SD rats. TNF-α induced LOX-1 expression in a dose- and time-dependent manner in endothelial cells. TNF-α induced ROS formation, phosphorylation of NF-κB p65 and ERK, and LOX-1 expression, which were suppressed by rotenone, DPI, NAC, and CPT. NF-κB inhibitor BAY11-7082 and ERK inhibitor PD98059 inhibited TNF-α-induced LOX-1 expression. CPT and NAC suppressed TNF-α-induced LOX-1 expression and phosphorylation of NF-κB p65 and ERK in rat aorta. These data suggested that TNF-α induced LOX-1 expression via ROS activated NF-κB/ERK pathway, which could be inhibited by CPT. This study provides new insights for the anti-atherosclerotic effect of CPT.
