Objective To evaluate the importance of the prenatal diagnosis to fetus with mild ventriculomegaly ( MVM) in pregnancy outcome and prognosis. Methods The ultrosonographic results of 51 pregnant women who were admitted to our hospital were collected in this study. In each case,a thorough evaluation of fetal anatomy was performed,karyotyping or MRI was done if needed,and follow-up was done un-til afterbirth. Results In 51 cases of lateral ventriculomegaly fetal:ultrasonography indicated there were 26 fetuses with mild ventriculomega-ly. The incidence of MVM complicated with other abnormities was 46. 0%,and that complicated with chromosome disorder was 11. 5%. Con-clusion Ultrasonography plays an important role in the detection of MVM. Chromosome analysis should be carried out for elder pregnant women when their fetuses are diagnosed as MVM and other complicating abnormities.

Objective To analyze the current status of the drug resistance of enterococci and monitor the prevalence of drug-resistant strains of enterococci in hospital infection. Methods 318 strains of enterococci separated from infectious samples in nine general hospitals in Hubei were assayed and tested with regard to drug sensitivity and the software of WHONET4 was used to analyze the data. Results The separation ratio of ARE, HLARE, VRE and ARE complicated with HLARE was respectively 16.98% , 37.76% , 0 and 5.66% . Conclusion The drug resistance of enterococci shows the tendency of increasing and consequent hospital infection shows the tendency of scattered prevalence. Laboratories of clinical microorganisms ought to closely watch the detection and spread of VRE.

BACKGROUND: The incidence of mental problems in adolescents is increasingly higher and has gradually become an important factor affecting their health and growth.OBJECTIVE: To probe into the mental health status and its influencing factors in adolescents in some cities and rural areas in Hubei Province.DESIGN: Clustering stratified random sampling, cross-sectional survey.SETTING: Department of Maternal, Child and Adolescent Health, Tongji Medical College, Huazhong University of Science and Technology.PARTICIPANTS: According to the selected investigation spots of National Surveillance of Constitution and Health of Students, we selected representative urban areas (Wuhan City and Huangshi City) and rural areas (Yun County, Xiantao City, and Xiaogan City) in Hubei Province as sample spots. Totally 1 498 adolescents, aged 16-18 years, were surveyed by clustering stratified random sampling. There were 605 adolescents in urban group and 893 in rural group.METHODS: The self-made survey scale was used to investigate general conditions, such as age, parents' occupation and educational level, family type, social atmosphere, school type and atmosphere, and interpersonal relationship. Symptom Checklist-90 (SCL-90) was used to determine the adolescents' mentalhealth status; 9 subscales (somatization, obsessivecompulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychosis) were set as the observation indexes. SCL-90 is an inventory which is rated on a 5-point scale. Factor score of SCL-90 ≥ 3 or total score ≥ 160 was considered mental disorders. The family educational pattern was investigated through Egma Minnen av Bardndosnaupporstran(EMBU) by questionnaires. It contained positive rearing pattern and negative rearing pattern. Positive rearing pattern (namely, affectional warmth and understanding) contributes to mental health, while negative rearing pattern (e.g. punishment, firm control, excessive interference, partialism or rejection, denial and excessive protection) is adverse to mental health. The family environment was investigated with Family Environment Scale(FES). Four subscales (intimacy, conflict, intellectual-cultural orientation, and positive-recreational orientation) with high reliability and validity were set as indexes. All participants were given unified instructions and required to fill in anonymous questionnaires. The questionnaires were then collected by the teacher in charge of the class.Some indexes of adolescents in the urban and rural areas were observed including the score of SCL-90 and its relation with general conditions,parental rearing pattern and family environment quality. The total scores of symptom checklist 90 were set as dependent variables for stepwise regression analysis of related factors.MAIN OUTCOME MEASURES:①The incidence of mental health ,gender and regional difference of adolescents in some cities and rural areas in Hubei province; ②The score of SCL-90 and its comparison with national norm;③Correlation analysis of the total scores of SCL-90 with general condition and parents' educational type.RESULTS: ① The general incidence of mental disorders was 18.13 ％ in the 1 498 adolescents in Hubei province. It was 18.20% in boys and 18.04% in girls with no significant difference (P ＞ 0.05). Regional differences: The incidence in rural areas [23.74% (212/893)] was significantly higher than that in urban areas [16.69% (101/605), P ＜ 0.05]. Among all kinds of mental disorders, compulsion, interpersonal sensitivity, hostility,paranoid ideation, and depression were more common. ② Comparison with the national norm: The factor scores of SCL-90 and family environmentalquality were significantly lower that those of the national norm.③ Single factor analysis: The total score of SCL-90 was obviously correlated with age, gender, parents' educational level and expectation, and school atmosphere (P ＞ 0.01). It was negatively correlated with positive rearing pattern (affectional warm, understanding) (P ＞ 0.01), but positively correlated with negative rearing pattern (punishment, firm control, excessive interference,partialism or rejection, and denial). It had significant positive correlation with conflict and significant negative correlation with intimacy, intellectualcultural orientation and positive-recreational orientation(P ＞ 0.01).④Multiple factor analysis: The mental health status of the students was closely related to age, gender, parents' educational level and expectation, interpersonal sensitivity as well as school atmosphere, parental rearing pattern,and quality of family environment.CONCLUSION: The incidence of mental problems in adolescents in some urban and rural areas in Hubei Province is relatively high. Score factors of SCL-90 are all higher than those of the national norm and the mental health level is poor. This has obvious correlation with family factors including age, gender, parents' educational level and expectation, and school atmosphere. Moreover, the quality of family environment and parental rearing pattern are the major factors affecting their mental health.

ObjectiveTo study the single nucleotide polymorphisms(SNPs) in the ORF26 gene of HHV-8 in Kaposi's sarcoma(KS),and to assess their correlations with the clinical phenotype and mucosal invasion of KS.MethodsHHV-8 DNA was extracted with phenol-chloroform-isoamyl alcohol from paraffin-embedded tissue specimens obtained from 32 cases of KS(including 26 classic and 6 AIDS-related KS).The ORF26 gene of HHV-8 was amplified by nested-PCR followed by bidirectional sequencing.The software DNAStar and program Clustal W were used to assess the SNPs in the ORF26 gene.Statistical analysis was carried out by using the Fisher's exact probability test.ResultsHHV-8 DNA was detected in 30 of the 32 tissue specimens,and in all of the 6 AIDS-related specimens.The predominant SNPs were 981 T/C(n =12),1086 C/T(n =12) and 1139 A/C(n =12) in the ORF26 gene of the 30 strains of HHV-8.No significant difference was observed in the distribution of SNPs in ORF26 between different phenotypes of KS or between KS with and without mucosal invasion.ConclusionThe ORF26 SNPs of HHV-8 seem unrelated to the clinical phenotypes or mucosal invasion of KS.

Objective To evaluate left atrial (LA) function by real-time three-dimensional echocardiography (RT-3D) and speckle tracking imaging (STI) after circumferential ablation of pulmonay vein ostia for atrial fibrillation guided by carto mapping system. Methods Thirty patients who had ablation procedure for paroxysmal atrial fibillation were accepted echocardiography to estimate the LA function at pre-operation,3 days and 3 months of post-operation. The LA maximal, minimal and pre-systolic volume (LAVmax, LAVmin and LAVp), LA passive ejection fraction (LAPEF), LA active ejection fraction (LAAEF) were measured by RT-3DE respectively. The strain rate curve was acquired in each LA segment (anterior, posterior, lateral, inferior and septal) by STI. Systolic strain rate (SRs), early diastolic strain (SRe) and late diastolic strain rate(SRa) of each left atrial segments were measured. Results Comparing with preoperative,3 days post-ablation SRs,SRe and SRa decreased significantly in each wall of LA. After 3 months,SRa and SRe in anterior, inferior and septal were significantly improved, however, SRs showed no significant difference. LAVmax and LAVpre were significantly decreased. LAPEF and LAAEF were significantly improved. Conclusions The patients with circumferential pulmonary vein ablation were in a deterioration after three days. The pump function and conduit functions of left atrial were increased after 3 months.

Objective Surgical treatment of lung cancer needs to follow strict quality control standard for the aims of accuracy of pathological staging and potentially improved prognosis.However,there are short of studies related to surgical quality analysis.Methods One hundred and twelve patients were enlisted with the diagnosis of lung cancer and received surgical intervention in 2007.Surgical quality of these cases were retrospectively analyzed in compliance with three international standards,National Comprehensive Cancer Network (NCCN),American College of Surgeons’ Oncology Group (ACOSOG),and International Association for the Study of Lung Cancer (IASLC).Results No surgical death was reported in this group.According to NCCN,ACOSOG and IASLC standards,qualified operations were 82 cases (80.4％),73 cases (71.6％),45 cases (44.1％) in 102 cases with R0 resection,respectively.The median total lymph nodes,median mediastinal nodes,and N1 nodes were 27 (range 0-63),16.5 (range 0-43),and 10.5 (range 0-26),respectively.The median mediastinal node stations resected were 4 (range 0-6).In the mediastinum,stations of 4R,5,6 and 7 presented the highest frequency of receiving lymph node dissection.For N1 stations,10 and 12 were among the top list.For the whole group,1-year survival,3-year survival and 4-year survival were 92％ (95％ CI,89-95),67％ (95％ CI,62-72),57％ (95％ CI,52-62),respectively.Conclusion Quality control is the essential part of surgical treatment of lung cancer,which will facilitate the baseline standardization of clinical research.Since IASLC provides the strictest standard for lung cancer surgery,we suggest that all thoracic surgeons need to follow this standard to secure the accuracy of pathological diagnosis and for a potential better prognosis.
