Objective:To evaluate the in vitro antibacterial effect of cefozopran on the clinical isolate bacteria to provide reference for its clinical use. Methods:An AGAR double dilution method was used to determine the in vitro antibacterial effect of cefozopran on 14 classes, 127 strains pathogenic bacteria isolated from the respiratory and urinary tract infections, and compared with that of 3 commonly used marketed antimicrobial agents. The parallel experiments were repeated for 3 times to observe the final results. Results: MIC50 of cefozopran against 7 kinds of clinical isolate G+ strains including Staphylococcus aureus, Pyogenic streptococcus, Streptococcus pneumoniae, Streptococcus, Methicillin-sensitive Staphylococcus aureus ( MSSA) and Methicillin-sensitive Staphylococcus epidermidis ( MSSE ) was within the range of 0. 125 ~ 1 μg·ml-1 and MIC90 was within the range of 0. 5 ~ 8 μg · ml-1 . Average MIC of cefozopran against Klebsiella pneumoniae, Escherichia coli, Proteus mirabilis, Haemophilus influenzae, Enterobacter aerogenes, Pseudomonas aeruginosa and Enterobacter cloacae was 0. 23,0. 21,0. 42,4. 74, 6. 31,8. 75 and 16. 35 μg ·ml-1 , respectively. Conclusion: Cefozopran shows obvious in vitro antibacterial effect on respiratory and urinary tract infection strains with significant antimicrobial activity in vitro.

Objective To study the causes of the uterus rupture in an outlying district and prevent measures.Methods 17 cases of the uterus rupture in Yongshun county hospital were retrospectively analysized.Results Among 17 cases of uterus rupture,the average antenatal care was 0 4 times every pregnant women,bleeding volume were 1100 ml,12 cases of shock(70 6%) ,5 cases forced uterectomy(29 4%), 16 cases of perinatal death(94%). According to stages of taking place : ⑴15 cases had taken place during laboring without appointing inpatient ,13 patients giving birth at home while 2 patients in hospital , average total stages of labor 29.4h, abnormal fetal positions 14 cases, including 3 cases of primipara and 12 cases of multipara. ⑵ 2 cases of spontaneous uterus rupture occurred during pregnancy who have with the cesarean section history performed in small clinic in the country side.Conclusions In an outlying district, main causes of uterus rupture:⑴ Ignored antenatal care. ⑵ Producing at home so that dystocia were not dealt with properly during stage of labor, another was women with prolong labor treated incorrectly . ⑶ The Spontaneous rupture during pregnancy were close related to the history of the classical cesarean section .To prevent the uterus rupture should be enhanced prenatal care and examination forced pregnant women delivery in hospital, standarding medical practice of performing operation, so doing could sharply decrease the pregnant uterus rupture in an outlying district.

Objective To investigate the effect of Calponin-1 suppression on human myometrium cells through adenovirus mediated siRNA. Methods Human uterine smooth muscle tissues were digested with enzymes, cultured and confirmed with immunocytochemistry. Aadenovirus siRNA-Calponin-1 plasmid was transfected into primary cultured uterine smooth muscle cells in vitro. The expressions of Calponin-1 mRNA and protein were analyzed by RT-PCR and Western blot, respectively.Results The pAdEasy-pShuttle-U6-Calponin-1 siRNA plasmid was successfully constructed, and Calponin-1 siRNA mediated by recombinant adenovirus resulted in markedly reduced expression of Calponin-1 mRNA and protein in human myometrium cells. The gray values of Calponin-1 mRNA in the uterine smooth muscle cells in the experimental, blank control, and empty vector groups were 316.3±39.2, 1048.5±126.4 and 1027.2±127.5, respectively. The gray values of Calponin-1 protein were 323.3±43.2, 1021.5±143.4, and 1019.2±144.5,respectively. The difference between the experimental group and the blank control group as well as the empty vector group was significant (P< 0.05). There was no significant difference between the empty vector group and the blank control group (P>0.05).Conclusion The pAdEasy-pShuttle-U6-Calponin-1 siRNA plasmid can inhibit the expression of Calponin-1 in human myometrium cells in vitro,which may be a useful approach to determine the role of Calponin-1 in delivery.

Fetal alloimmune thrombocytopenia (FAIT) is a severe perinatal complication, which can seriously affect fetal development, and may even lead to intrauterine hemorrhage and intrauterine death. There are controversies in the clinical diagnosis and treatment of the disease due to its low incidence and limited treatment experience. This paper reviews the progress to date in understanding the condition, incidence, screening of high-risk factors, prenatal and delivery management of FAIT based on domestic and foreign guidelines, in order to help obstetricians in the clinical management of FAIT.

0.05). Conclusions Oxytocin, misoprostol or nimodipine can induce or inhibit labor through regulating expressions of VDCC L ? 1 and VDCC L ? 2 mRNA in the rat uterine myometrium and it may not have an adverse effect on heart function of normal pregnant rats. VDCC L may be the common channel of labor induced by internal or external factors.

Objective To investigate the significance of sequential continuous sonography approach (SCSA) in diagnosing fetal deformity during prenatal stage. Methods Compared with postpartum data, the sequential continuous sonography of 16685 fetuses during gestational age 14 to 40~(+3) weeks. 1 were ana-lyzed retrospectively. Results 498 abnormal cases in 514 abnormal fetuses were scanned out with sequen-tial continuous sonography approach, and 16 cases were not successfully diagnosed by SCSA during prenatal stage. The rate of final diagnosis on deformity fetuses by SCSA was 96. 89%, the rate of misdiagnosis was 3. 1%. Conclusion Sequential continuous sonngraphy approach is a useful tool for diagnosing fetal de-formity during prenatal stage, h should be widely applied into the clinical inspection for prenatal diagnosis.

OBJECTIVE: To investigate the application of modified cesarean hysterectomy for placenta previa percreta in the third trimester via peritoneum lateral approach. METHODS: Data of 8 patients at 34 weeks or more gestation, who underwent cesarean hysterectomy for placenta previa percreta in Xiangya Hospital, Central South University, between January 2008 and December 2011, were analyzed retrospectively. The patients were divided into a modified cesarean hysterectomy by peritoneum lateral approach group (modified group, n=4) and a conventional cesarean hysterectomy group (conventional group, n=4), according to the principles of the case-control and the operation performed by the same doctor. The incidence of blood loss, the number of transfusions of RBC, and the ocurrnce of complications were compared between the 2 groups. RESULTS: The blood loss in the modified group and the conventional group was (2280±687) mL and (6150±2023) mL, and the number of transfusions of RBC was (4.5±2.1) U and (11.7±8.9) U, respectively. There was no coagulation disorder and ureteral injury in the modified group whereas there were 2 disorders and 1 injury in the conventional group. Two patients with bladder laceration were observed in the 2 groups. CONCLUSION Large amounts of bleeding will be onset in the placenta previa percreta. Modified cesarean hysterectomy for placenta previa percreta can reduce the blood loss and the incidence of related complications in the operation.

Objective To investigate the impact of early onset of intrahepatic cholestasis of pregnancy on maternal and fetal umbilical artery blood biochemical parameters, and the effects of perinatal infant prognosis. Methods Pregnancy before 28 weeks 45 cases of the disease were acted as early-onset group, 163 cases of the disease after 28 weeks of pregnancy as late-onset group, 100 cases of single pregnancy health pregnant women were chose as control group. Results The serum TBA, TBIL, DBIL, CG, ALT, AST levels and the disease severity of three groups were statistically significant (P <0.05). The serum TBA, TBIL, DBIL, CG, ALT, AST of three groups were statistically significant (P <0.05). Umbilical artery serum TBA, NSE, cTnI, lactic acid, pH value of three groups were statistically significant (P <0.05). Maternal serum and neonatal serum TBA umbilical artery, NSE, cTnI were positively correlated(P <0.05). Early-onset group had worse prognosis late-onset group (P<0.05). Conclusion Pregnancy 28 weeks pregnant before the onset of intrahepatic cholestasis of more serious illness, the impact on biochemical indicators of more significant biochemical parameters before delivery after treatment, although improved, but still significantly affect fetal umbilical artery injury-related indicators such as NSE, cTnI, lactate levels, with higher premature birth rate, poorer prognosis of perinatal children.

Objective To investigate the impact of the implementation of free-position active at the stages of labor maternity outcomes. Methods The proposed transvaginal delivery primipara 220 cases were randomly divided into intervention group and control group,each of 110 patients, the control group used conventional supine position of the active, intervention group treated with a free-position active management, the rate of first exposed decline, the first,second and third of the total labor time and, finally adopted the mode of delivery, birth weight, Apgar score, 24h postpartum hemorrhage, maternal and neonatal complications of fetal activity were observed. Results The intervention group decreased fetal speed were significantly faster than the control group (P<0.05), the first and second stage of labor and total labor were significantly shorter than the control group (P<0.05). In the intervention group, vaginal delivery rate was significantly higher than the control group (P<0.05), vaginal delivery, cesarean section rate were significantly lower than the control group(P<0.05),birth weight, Apgar score between two groups,the difference were not statistically significance (P>0.05). In the intervention group, 24 h postpartum hemorrhage were significantly less than the control group (P<0.05), hemorrhage, urinary retention, neonatal asphyxia were significantly lower than the control group (P<0 . 05). Conclusion The implementation of active labor freedom fetal position can help decrease shorten the production process,improve the rate of vaginal delivery,reduce maternal and neonatal morbidity .

OBJECTIVE: To evaluate the value of selective arterial occlusion in the treatment of placenta percreta in late trimester of pregnancy. METHODS: Fifteen clinical patients ( gestational age ≥34 weeks), diagnosed with placenta percreta in Xiangya Hospital of Central South University from January 2003 to December 2010, were retrospectively analyzed. According to whether the selective arterial occlusion was used or not, the 15 patients were divided into 2 groups: an arterial occlusion group (n=8) and a non-arterial occlusion group (n=7). Based on the time of occlusion, the arterial occlusion group was divided into a prophylactic occlusion subgroup (n=4) and a remedial occlusion subgroup (n=4) (including 1 patient who was performed after the iliac artery balloon was taken out ). The blood loss, the rate of hysterectomy and complications were compared between the arterial occlusion group and the non-arterial occlusion group. RESULTS: In all 15 patients, the average amount of blood loss was 3813 mL, and the rate of hysterectomy was 73.3% (11/15). The recent complication rate was 20.0% (3/15, including 2 blood coagulation dysfunctions and 1 lower extremity thrombosis), and long-term complication was not found. The average amount of blood loss in the occlusion group was 2512 mL, the hysterectomy rate was 62.5%(5/8); while the average amount of bleeding was 5549 mL and the hysterectomy rate was 85.7% in the non-occlusion group (6/7). There was significant difference between the 2 groups (P<0.05). The average amount of blood loss and the rate of hysterectomy in the prophylactic occlusion subgroup were lower than those in the remedial occlusion subgroup (1350 mL vs 3600 mL, 60.0% vs 66.7%, P<0.05). CONCLUSION Patients with placenta percreta in the third trimester of pregnancy may encounter severe postpartum hemorrhage, and the rate of hysterectomy is high. The amount of blood loss and the rate of hysterectomy may be reduced by the selective arterial occlusion before or in the cesarean section, but cannot be avoided completely.
