Objective To investigate the effects of treatment of syphilis in pregnancy on perinatal prognosis. Methods Patients of syphilis in pregnancy from Hainan Provincial People′s Hospital and Haikou Municipal Maternal and Child Health Center during 1995.1 to 2001.1 were collected for retrospective analysis. Pregnant women with syphilis were divided into treated group and untreated group according to whether they received penicillin anti syphilis treatment or not during pregnancy. Results The total number of deliveries in the 2 hospitals during that period was 18 701, and 61 out of 9 805 women screened for syphilis were positive, giving an incidence of 6 2/1000. The perinatal mortality rates were 11 2% in treated group and 83 3% in untreated group, and incidences of congenital syphilis were 17 6% and 72 7% respectively. Conclusion Syphilis in pregnancy is a serious complication to harm the fetus. Screening of syphilis during pregnancy is necessary, and penicillin treatment is effective which may reduce the perinatal mortality rate and the birth of congenital syphilis baby.

Objective To explore the effect of action research based on group learning in hospice care module for nursing students. Methods 82 students were divided into cooperative learning group (40) and conventional teaching group (42). The cognition and attitude of good death questionnaire was used to evaluate teaching effect before and after teaching of hospice care. After teaching, self-feedback and self-feedback questionnaire were made to evaluate the effect of cooperative learning group. SPSS 17 was used to make comparison of data between groups and within groups, and t test, chi square test or Fisher exact probability 2 were also used . Results There were no difference between two groups of nurses before teaching. The students' cognitive level and attitude in cooperative learning group increased significantly, especially their cognitive level of physiological needs (t=5.398, P=0.001), cognition and attitude of death education in intervention group was higher than control group (t=2.992, P=0.004; t=3.661, P=0.001). Although 95% of the nursing students of the cooperative learning group thought group cooperative studying could improve their interests and cultivated their comprehensive abilities, only 50% could accept this kind of studying methods . Conclusions Action research based on group cooperative studying can improve students' cognitive level and attitude of good death, and it is also good for cultivating their ability of au-tonomous learning, innovation, cooperation, and meanwhile, educational action research is a good way to improve both teaching effect and research ability of teacher staffs, but in practice, students' acceptance of group learning needs to be improved.

Objective To observe the dynamic changes of interferon gamma(IFN-?) and transforming growth factor bata1(TGF-?_1) in animal model of hyperoxia-induced lung injury,and to explore the mechanism of fibrosis.Methods Thirty-two juvenile Wistar rats were randomly divided into room-air group and hyperoxia group,the hyperoxia group were further divided into 3 subgroups of hyperoxia-exposure for 3,7 and 14 days.The mRNA levels of IFN-? and TGF-?_1 in the lung were measured by reverse-transcription polymerase chain reaction(RT-PCR).The expressions of IFN-? and TGF-?_1 protein were measured by immunohistochemical(stai)-ning.Results The level of IFN-? mRNA of groups under hyperxia-exposure for 3,7 and 14 days were higher than that of control group.The expression of IFN-? mRNA notably elevated and was up to its peak(P

This study aims to compare the urate-lowering response rate of febuxostat and allopurinol in gout patient using a model-based meta-analysis. The literature search identified 22 clinical trials of gout with a total of 43 unique treatment arms that met our inclusion criteria, and a total of 6 365 gout patients were included in the study. The response rates of allopuriol and febuxostat were characterized by Tmax model and Emax model respectively, and the effect of baseline serum uric acid (sUA) and patient type on the drug effect was tested. The results showed that allopurinol can reach an average maximum response rate of 50.8% while febuxostat can reach a 100% response rate within a very short time, and the ED50 was 34.3 mg. Covariate analysis revealed that baseline sUA has a negative effect on response rate of allopurinol, and a positive effect on the predicted ED50 of febuxostat. For patients who had shown inadequate response to prior allopurinol treatment, the average response rate was about half that of the allopurinol responder patients.

Objective To assess the safety and effectiveness of nasegastric enteral nutrition (NGEN) in patients with severe acute pancreatitis (SAP).Methods A meta-analysis of all the relevant clinical trials was performed.Clinical trials were identified from the following electronic databases:Medline,EMBASE,the Cochrane Controlled Trials Register,and Chinese Bio-medicine Database.The search was undertaken in October 2008.The literature quality was evaluated with Cochrane Handbook 5.0.The statistical analysis was performed by RevMan 4.2 software.Results Four trials involving 157 patients were included.The combined results showed that no significant differences in the safety and tolerance between nasogastric and conventional routes in patients with SAP.Conclusions Currently available data show early NGEN appears to be effective,safe,and tolerable in patients with SAP.However,more large-scale high-quality trials are required to further elucidate this topic.

This study was aimed to collect relevant provisions of bulging disease medical records in the Ming and Qing dynasties to excavate the syndrome differentiation, drug law and medication frequency analysis. A database was established to analyze relevant provisions. The results showed that the syndromes of liver stagnation and spleen deficiency, dampness-heat accumulation, spleen-yang deficiency are the most common type. The mainly used drugs are from the category to eliminate dampness and water, and to tonify the deficiency. The top three used drugs are poria, atractylodes, and dried citrus peel. It was concluded that medications used in the Ming and Qing dynasties were mainly targeted to the disordered zangfu-organ, which was mainly about the spleen and the stomach. The syn-drome differentiation is the mixture of deficiency and excess. And deficiency is the main part. The medication should combine tonification and reducing. And tonification should be paid attention to. The syndrome differentiation and treatment should be coordinated and the primary and secondary aspect should be identified. These rules provide ref-erence effect for the clinical practice and scientific research of bulging disease treatment.

Objective:To investigate the value of B ultrasonography in the early diagnosis of transient synovitis of hip (TSH) in dogs, and provide the valid base and data for the clinic early diagnosis of TSH. Methods:Eighty 2-3 month old dogs were injected 2‰noradrenalin (NA) into the hip joint induced TSH. We observed 5 assessments that included the 99mTC-MDP triphasic imaging, X ray, B ultrasonography, the synovial lfuid and the pathological tissue check in different time. Results:Early course of TSH presented the synovium of joint hemangiectasis, hyperaemia, synovium villus hyperplasia, edema, and joint inflammatory exudation. The ischemia of local blood supply of the femoral head was observed by 99mTC-MDP triphasic imaging. Ultrasonography showed the broadening of the anterior space of the hip, but the X ray showed no valid changes.Conclusion:B ultrasonography can report the early changes of TSH and may be used in the early diagnosis of TSH in children.

BackgroundHigh myopia is one of leading causes of blindness,so far the pathogenesis remains unclear.Two single-nucleotide polymorphisms (SNPs) of rs6885224 and rs12716080 in CTNND2 gene were recently found to be associated with high myopia in Singaporean Chinese.But whether these SNPs are related with the pathogenesis of high myopia in Han Chinese is worth studying,Objective This study was to investigate the relationship between the genetic variations of the CTNND2 gene and high myopia in Han Chinese.MethodsA case-controlled association study was designed.Nine hundred and thirty-three individuals with high myopia and 1227age- and gender-matched normal subjects were included in this study.The 5 ml of periphery blood was obtained from all subjects for the extraction of genomic DNA.The target DNA was amplified using PCR and purified by the SNaPshot method.Four SNPs rs12716080,rs917012,rs6885224 and rs16901340 in the CTNND2 gene were genotyped.This study was approved by the Ethic Committee of Sichuan Provincial People Hospital.Written informed consent was obtained from each subject before his/her enrollment.Results The frequencies of the genotypes rs6885224,rs12716080,rs917012,rs16901340 SNPs were in Hardy-Weinberg equilibrium (HWE) ( P=0.181,0.085,0.732,0.313,0.264,0.663,0.084,0.196).There were no significant differences in genotypes frequency distribution ( in turn P =0.654,0.406,0.828,0.403 ) and allele frequency distribution of the CTNND2 gene ( in turn P =0.377,0.209,0.743,0.198) between the high myopia group and normal control group.The haplotypes (TA and GA)frequencies of rs12716080 and rs917012 in the high myopia group were significantly different from those of the normal control group(TA:0.784 vs.0.719;GA:0.087 vs.0.136) (x2 =6.115,P=0.013 ;x2 =6.634,P=0.010),but those of GG were similar between the high myopia group and normal control group ( 0.123 vs.0.143,x2 =0.889,P =0.346). ConclusionsThe SNPs rs12716080,rs917012,rs6885224 and rs16901340 in CTNND2 gene were not responsible for high myopia,however,the haplotypes of rs12716080 and rs917012 are susceptible for high myopia in Han Chinese.

ABSTRACT:Objective To analyze the stress changes of tooth tissues in the medial-occlusal (Class Ⅱ)cavity restored with different kinds of inlay materials by the three-dimensional (3-D)finite element.Methods The inlay restored 3-D finite element model of medial-occlusal (Class Ⅱ)cavity was established by CBCT scanning method and reverse engineering software Mimics,Geomagic Studio,Pro/E5.0 software,and finite element analysis software. The Von-mises stress and change tendency of tooth tissues and four different kinds of inlay materials were compared after taking vertical loading and tongue 45°to loading.Results There were different stress levels of tooth tissues among different inlays of medial-occlusal (MO)Class Ⅱ cavity.The stress level of the cobalt chromium alloy inlay was the largest,the stress level of the gold alloy inlay was lower,and the stress level of the composite inlay was the lowest.Dental tissues stress distribution was similar for the four different restorative materials,and focused on hole bottom of dentin near the pulp in dentin.Conclusion Compared with ceramics,gold alloy and cobalt chromium inlay restoration,restoration with composite resin inlay can reduce the organization stress of the remaining tooth in the medial-occlusal (Class Ⅱ)cavity type.
