OBJECTIVE:To study the adhibition of misoprostol combined with palace cavity attraction tube in the treatment of painless abortion after cesarean section. METHODS:214 patients who received painless abortion after cesarean section were ran-domly divided into group A(71 case),group B(71 case)and group C(72 case). After all patients were given conventional intrave-nous anesthesia,Group A was given misoprostol 0.6 mg for oral administration in preoperative 2 h. Group B was given Misoprostol tablet 0.2 mg abrasive powder put in posterior fornix in preoperative 3 h. Group C did not give any drugs. All the groups used dis-posable suction curettage tube. The efficacies of sedation and cervical dilatation,operation time,intraoperative blood loss,recovery time,dosage of propofol and incidences of complications and adverse reactions in the 3 groups were observed. RESULTS:The op-eration time,intraoperative blood loss in group A were lower than group B and lower than group C,the differences were statistical-ly significant(P<0.05);recovery time and dosage of propofol in group A were lower than group B and C,the differences were sta-tistically significant(P<0.05),howerer,there was no significant difference between group B and C(P>0.05). The total effective rates of sedation and cervical dilatation in group A and B were significantly higher than group C,and the difference was statistical-ly significant(P<0.05),however,there was no significant difference between group A and B(P>0.05). The incidence of compli-cations in group A was lower than group B and lower than group C,and the difference was statistically significant (P<0.05). There was no significant difference in the incidence of adverse reactions among 3 groups(P>0.05). CONCLUSIONS:The efficien-cy and safety of misoprostol for oral administration or medicated vaginal suppository combined with palace cavity attraction tube in the treatment of painless abortion after cesarean section is similar,but oral administration can reduce the dosage of anesthetics,op-eration time and smaller intraoperative blood loss volume.

Objective To assess the performance capability of syphilis serology among STI laborato-ries in Guangdong Province. Methods Positive and negative sera samples were prepared and delivered toSTI laboratories. Non-treponemal and treponemal quantitative and qualitative tests were performed with these samples based on standardized procedures. Quality and proficiency of syphilis serology among these labora-tories were evaluated. Results A total of 225 STI laboratories in Guangdong Province participated in this survey, 3696 serological tests for syphilis were performed from 2004-2006. The outcomes showed that the total reproducibility among participating laboratories increased from 82.5% in 2004 to 90.0% in 2006 (x2 =16.8, P ＜ 0.05), and the percentage of laboratories with a performance level higher than the provincial average level rose from 64.7% in 2004 to 76.8% in 2006. The total reproducibility was 95.5% for non-treponemal qualitative tests,95.0% for treponemal qualitative tests, 82.1% for non-treponemal quantitative tests, and 81.1% for treponemal quantitative tests. The false-negativity and false-positivity rates were 4.7% and 4.0%,respectively, for non-treponemal qualitative tests, and 7.2% and 0.4%, respectively, for treponemal qualitative tests. Conclusions It is important to do capability building and improve the performance of STI laborato-ries, in order to prevent and control syphilis.

Objective To explore the tabular condition assessment methods in the role of early warning of children with severe hand, foot and mouth disease. Methods A total of 267 patients in observation group were evaluated by the disease assessment scale of hospitalized children with hand, foot and mouth disease and the risk assessment form of severe children with hand, foot and mouth disease to early indentify the severe and give intervention treatment. And the 243 patients in control group were evaluated by the empirical method. The incidence of severe cases and the incidence of complications were compared between two groups. Results The incidence of severe cases was 3.00%(8/267) in observation group and 17.70%(43/243) in control group, and there was significant difference between two groups, χ2=30.970,P<0.01. The incidence of total complications was 9.74%(26/267) in observation group and 32.51%(79/243) in control group, and there was significant difference between two groups, χ2=34.74,P<0.01. Conclusions The tabular condition evaluation method can early identify the children with severe hand, foot and mouth disease and give early intervention, reduce the incidence of severe and critical cases, and reduce the complications.

Objective To observe the clinical efficacy of puncturing Tianshu (ST 25) alone in treating intractable constipation in the elderly.Method Totally 193 senile subjects with intractable constipation were randomized into group A of 57 cases, group B of 73 cases, and group C of 63 cases. Group A was intervened by acupuncture at Tianshu (ST 25), group B was by Lactulose oral solution, and group C was by retention enema. The clinical efficacies and effect-lasting time of the three groups were compared. Result The total effective rate was 89.3% in group A, versus 88.6% in group B and 92.1% in group C, and the between-group differences were statistically insignificant (P>0.05). Of the markedly effective and improved cases, the effect-lasting time in group A was significantly different from that in group B and C (P<0.01).Conclusion Acupuncture at Tianshu (ST 25) alone is an effective method in treating senile intractable constipation.

Objective To evaluate stepping DSA technology in lower extremity artey disease. Methods 12 cases performed with stepping DSA in lower extremity artery were examined with TOSHIBA Infinixi digital subtraction angiography system, of which, 8 ones were also examined with conventional DSA. Results Stepping DSA technology could decrease the dosage of contrast agent and the examination.

Objective To investigate the expressions of Apaf-1 and Caspase-9 protein in ovarian serous carcinoma(OSC) and their clinicopathological significance.Methods The expressions of Apaf-1 and Caspase-9 protein in 45 cases of OSC,60 cases of ovarian serous cystadenomas and 32 cases of ovarian borderline serous cystadenomas were detected by immunohistochemical SP method.The relationship between the expressions of these two proteins and the clinicopathological features of OSC and the correlation between Apaf-1 and Caspase-9 expressions in OSC were analyzed.Results The positive rates of Apaf-1 in OSC,ovarian serous cystadenoma and ovarian borderline serous cystadenoma were 24.4%(11/45),75.0%(45/60) and 46.9%(15/32),the difference was statistically significant (χ2=26.734,P<0.01).Apaf-1 expression was correlated with pathological grade,clinical stage and lymph nodes metastasis (χ2=6.318,7.565,5.554,P<0.05).The expression rates of Caspase-9 in OSC,ovarian serous cystadenoma and ovarian borderline serous cystadenoma were 28.9%(13/45),83.3%(50/60) and 56.3%(18/32),the difference was statistically significant (χ2=31.682,P<0.01).The expression of Caspase-9 was correlated with pathological grade,clinical stage and lymph nodes metastasis (χ2=5.750,4.391,5.466,P<0.05).In OSC,the expressions of Apaf-1 and Capase-9 were positively correlated (k=0.433,P=0.003).Conclusion The low expressions of Apaf-1 and Caspase-9 in OSC may be related to the occurrence and development of OSC.
