Objective To learn the immunity level of Neisseria meningitides (Nm) serogroup W1 35 among healthy population.Methods A total of 410 children aged 0 -14 years were selected by stratified random sampling method in Zhuji city.The polysaccharide antibody IgG level of Nm serogroup W1 35 was detected by ELISA.The antibody concentrations more than 2 μg/mL were identified as positive.Results The geometric mean concentration (GMC)was 1.46 ±0.25 μg/mL and the W1 35 -antibody positive rate was 4.63%.There was no difference on antibody GMC and the W1 35 -antibody postive rate among different region and gender groups.There were statistical differences on antibody GMC among different age groups (P<0.05).The antibody GMT in the age group 15 -34(1.63 ±0.28 μg/mL )was significantly higher than that in other age groups(P <0.05),and the antibody GMT in the age group 1.5 -4 (1.37 ±0.19 μg/mL)was significantly lower than that in the age group 5 -14 (P <0.05).The antibody GMT were significantly lower in the elderly (≥60 years old)than that in the age group <10 and 5 -14(P <0.05).Conclusion The immunity level of Nm serogroup W1 35 among healthy population is low,and it is suggested to be immunized by the vaccines which contained Nm W1 35.

Objective To develop the clinical practice guidelines for the management of medication adherence to highly active antiretroviral therapy (HAART) in China. Methods The development methods included qualitative interview of 31 stakeholders, questionnaire survey of 423 PLHIV, adaptation of 30 clinical practice guidelines related to AIDS care, and overviews of reviews of 44 systematic reviews/Meta-analysis. Results 10 clinical practice guidelines and 10 systematic reviews/Meta-analysis were included. The clinical practice guidelines for the management of HAART were formed. Conclusions The formed clinical practice guidelines showed better applicability and higher general quality. It is recommended to use the guidelines in AIDS care.

Objective To identify the presence of candidate pathogenicity island 89K DNA sequence of Streptococcus suis serotype 2 (SS2) strains isolated from patient in Zhejiang province. Methods Genes and DNA fragments were amplified by PCR, using specific primers, and three amplified fragments of the89K sequence were directly sequenced. The results were analyzed using software related to bioinformaties and epidemiology. Results 8 strains of SS2 all contained 89K sequence, cps2J and mrp virulent genes, and species-specific 16S rDNA. 3 amplified fragments of 89K candidate pathogenicity island of SS2 ZJ0501 were above 99% similar to SS2 strain identified from outbreaks in Jiangsu in 1998, and the gene fragment of coding DNA recombinant protein in the 89K sequence was highly homological with that of S. dysgalactiae and S. agalactiae. Conclusion In recent years SS2 strains isolaed from patients with clinical symptoms in Zhejiang province had been detected to have contained candidate pathogenicy 89K DNA fragment.

OBJECTIVETo investigate the lymph node metastasis and its risk factors in T1-2 staging invasive rectal carcinoma.

METHODSThe data of 1116 patients with rectal cancer treated with total mesorectal excision (TME) technique from January 2000 to April 2009 was analyzed retrospectively. The clinicopathological factors analyzed included gender, age, primary symptom type, number of symptoms, duration of symptom, synchronous polyps, preoperative serum carcino-embryonic antigen level, preoperative serum CA19-9 level, the distance of tumor from the anal verge, tumor size, tumor morphological type, tumor circumferential extent, tumor differentiation and tumor T staging. Statistical analysis was performed by using Logistic regression analysis and Chi-square test.

RESULTSA total of 1116 patients were enrolled, and 358 cases (32.1%) were classified as with T1-2 staging tumor. Two cases (5.6%, 2/36) in patients with a T1 staging tumor were found with lymph node metastasis, and 75 cases (23.3%, 75/322) in patients with a T2 staging tumor, respectively. Compared with patients with T3-4 staging tumor, lymph node metastasis rate of the patients with T1-2 staging tumor was significantly lower [21.5% (77/358) vs. 51.6% (391/758), P < 0.05]. Only the tumor T staging was found as the independent risk factor for the lymph node metastasis in patients with T1-2 staging tumor on multivariate Logistic regression analysis (odds ratio: 5.162; 95%CI: 1.212 to 21.991; P = 0.026).

CONCLUSIONSA substantial proportion of T1-2 staging rectal cancers harbor metastatic lymph nodes and the clinicopathological features except for T staging fail to predict the lymph node metastasis. Further research is warranted to identify the risk factors and guide the clinical practice in patient with T1-2 staging tumor.

Objective To study the genotyping distribution of the Yersinia pestis(Y.pestis)strains by characterizing the diversity of the insertion sequence IS100 within the Y.pestis genome.Methods Derived fromthe known sequence of oriental strain CO92,5 pairs of locus-specific primers originating from both sides of the adjacent region of IS100 copies were designed,and two other complementary primers inside the IS100 sequence were designed to correspond with the outer primers.Then,91 Y.pestis strains and l pseudotubebculosis strain were tested by the specific PCR method using the primers described above and the PCR products were conformed by the sequence analysis,then further analysis WaS performed after the IS100 status was marked on the map of the plague focus type of china.Results The 91 Y.pestis strains had different IS100 status in their genome on tested loci.some possessed IS100 insertion,some didn't,and others changed their genome constitution.The IS100 possession on the 5 loci also suggested a distribution of regionality.Conclusion The analysis of some IS100 insertion element loci reveals that the IS100 genotyping distribution is consistent with the plague focus of type of China.And IS100genotyping pattern of the Y.pestis stains well reflects its genome constitution and the high flowability in its natural evolution.

OBJECTIVETo discuss the diagnostic value of an ultrasonic assessing system for detecting the severity of hepatic fibrosis in patients with chronic hepatitis B (CHB).

METHODSUltrasonographic variables were analyzed in 110 CHB patients. An ultrasonic semi-quantitative scoring system using seven ultrasonic morphologic parameters, a Fisher discriminating function and three quantitative ultrasonic parameters was developed. The performance of these methods was also studied and compared.

RESULTSThe areas under the curve of the scoring system for different liver fibrosis stages were >or= S2: 0.946, >or= S3: 0.914, and S4: 0.915. The total score was well correlated with the histological stage of fibrosis (r=0.824, P < 0.001). There was a significant difference between the stages of fibrosis. The accuracy of the Fisher discriminating function for identifying three study endpoints was 76.5%, 78.2% and 67.3%. Combining the ultrasonic scoring system and the discriminating function, the specificity was 85%-90% and the accuracy was 77%-84%.

CONCLUSIONOur ultrasonic semi-quantitative scoring system is a noninvasive method for quantitating liver fibrosis. If it is used together with a discriminating function, the accuracy of diagnosing liver fibrosis can be significantly increased.
