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 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 analyze the components of the volatile oil in different parts of Lonicera japonica Thunb.from Henan province.METHODS:The volatile oil was extracted from the buds,leaves,stems of L.japonica Thunb.by solid-phase micro-extraction,and the chemical compositions were identified by GC-MS combined with Kvotas retention index.The relative percentage of each constituent was determined by GC area normalization method.RESULTS:Thirty-nine compounds were identified from different parts of L.japonica Thunb.from Henan province,and seven of which were mutual in the buds,leaves,stems of L.japonica Thunb..CONCLUSION:This study serves as a scientific basis for the further development and utilization of L.japonica Thunb..

OBJECTIVE: To analyze the volatile components in the Eriobotrya japonica by headspace solid-phase microextraction-gas chromatography-mass spectrometry(SPME-GC-MS) and to optimize the operating conditions for SPME.METHODS: DB-5 MS elastic silica capillary column(30.0 m?250 ?m?0.25 ?m) was used as the chromatographic column with helium of high purity(99.999%) as carrier gas at a flow rate of 1.0 mL?min-1.The injector temperature was 250 ℃;MS condition: ionization mode was EI with electron energy of 70 eV and the mass scan range of 30～440 amu.RESULTS: After headspace absorption for 30 min at 80 ℃ using 65 ?m polydimethylsiloxane-divinyl-benzene extraction head followed by desorption for 1 min at 250 ℃,the E.japonica sample was separated and identified by GC-MS analysis.A total of 34 peaks were obtained and 29 components were identified which accounted for 97.42% of the total peak area,topping the list were benzaldehyde and 4-methoxybenzaldehyde.CONCLUSION: HS-SPME-GC-MS can be used for the rapid analysis of the volatile components in E.japonica.

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.
