Objective To explore the relationship between social participation and needs for rehabilitation of the disabled in Guangdong Province and to make a proposal for developing the rehabilitation strategies. Meth-ods The data of the Second National Sample Survey of Disabled Persons in Guangdong Province was used in this study. Ranked data analysis was made with the sub-items of the social participation assessment and the main needs of the disabled individuals. Results Significantly statistical differences were revealed with regard to the constitu-ent ratio of needs for rehabilitation services among people with different degrees of difficulties in social participation caused by hearing and visual impairments as well as physical and mental disabilities. No significant difference was found in terms of the constituent ratio of rehabilitation needs among those with difficulties in speech and those with psychiatric diseases. The major rehabilitation needs focused on medical service, assistive apparatus support and functional trainings. Conclusions The rehabilitation needs were different among different categories of disabled persons. Rehabilitation services should be provided accordingly.

The purpose of this study was to determine the changes of pathogens in hematological ward and susceptibility of patients received chemotherapy to antibiotics. The pathogens were taken from blood, urine and sputum of patients who accepted chemotherapy from years 2001 to 2005, then were isolated and identified. The susceptibility test was performed by disk diffusion method. The results showed that the total of 418 strains were detected. Gram-negative bacteria were the most common of nosocomial infection. Pseudomonas aeruginosa, Enterobacter cloacae, E. coli account for the most of Gram negative- bacteria infection and most resistant to broad-spectrum penicillin, Acinetobacter baumannii showed a trend of increase. The ratios of gram positive bacteria and fungi were increased slowly, mainly as Enterococcus and Candida. Enterococcus is the most common cause of Gram-positive bacterial infection. Vancomycin resistance did not occur. It is concluded that Gram-negative bacteria are main cause of nosocomial infection in patients with hematological malignancies. Gram positive bacteria and fungi had been more frequent. Strains resistant to antimicrobial agents increase.

BACKGROUNDThe paralimbic system, which is composed of three parts, is an important functional unit. Gliomas located in the region remain a challenge for clinical treatment. However, the dynamic change of gliomas in the area has not been well documented. The purpose of this study was to identify the growth tendency of gliomas located in the paralimbic system and to obtain some suggestions for clinical treatment.

METHODSEleven cases of gliomas located in the paralimbic system were recruited in the study. All of them were proven by pathology. Analysis of the serial radiological examinations in each patient was performed from the initial to the final examination, taking into consideration the following items: initial tumor location, final location and the growth tendency.

RESULTSIn the initial and final examinations the ratios of insula involvement were 64% and 100%, respectively. On the other hand, the ratios of gliomas located in two or more parts of paralimbic system increased from 64% to 100% during the dynamic examination.

CONCLUSIONSEven though the paralimbic system is composed of three independent anatomical parts, gliomas tend to involve all three parts, especially the insula. Therapeutic plans should aim at the whole region of the system, even during the early stages of gliomas.

Organochlorine pesticides(OCP)exist widely in the environment,which may threaten human health and cumulate for years once absorbed in the body.OCP metabolites in the body are associated with metabolic disorders.In vivo and in vitro exposure of OCP could enhance hepatic fatty acid synthesis, and interfere in the β-oxidation of fatty acids by impairing the function and structure of mitochondria in hepatocytes. Moreover, OCP can increase secondary bile acid formation by modulating of gut microbiota and reduceing ileal bile acid re-absorption,resulting in compensatory increase of hepatic bile acid synthesis. This review summarizes the mechanism of fatty acid and bile acid metabolic abnormalities caused by OCP.

OBJECTIVE: To evaluate the effect of herceptin(trastuzumab) plus adjuvant chemotherapy on the prognosis of patients with human epithelial growth factor receptor 2 (HER2) positive early-stage breast cancer by Meta-analysis. METHODS: Search all of randomized clinical trials (RCTs) on herceptin plus adjuvant chemotherapy for HER2 positive early-stage breast cancer in MEDLINE, EMBase, Cochrane library, Clinical Trails, ASCO Conference data, CHKD, Wanfang Database, VIP information, scholar.google.com and SIGLE. A Meta-analysis was carried out by collecting information based on the inclusion and exclusion criteria from all papers available. RESULTS: The Meta-analysis included 4 trials. A total of 9116 patients were included in the analysis(4555 in the study group and 4561 in the control group). There were statistical differences between the study group(herceptin plus adjuvant chemotherapy) and the control group(adjuvant chemotherapy) in the disease-free survival rate [relative risk(RR)=1.08, 95% CI, 1.06-1.09, P<0.001], the overall survival rate(RR=1.01, 95% CI, 1.01-1.02, P=0.0003), the distant recurrence rate(RR=0.49, 95% CI, 0.42-0.57, P<0.001), and the cardiac events rate (RR=3.93,95% CI, 1.03-15.06, P=0.05). CONCLUSION Herceptin plus adjuvant chemotherapy can improve the disease-free survival rate and the overall survival rate, decrease distant recurrence rate of patients with HER2 positive early-stage breast cancer, but may cause heart toxicity, especially when combined with anthracycline (doxorubicin).

BACKGROUNDLive attenuated hepatitis A vaccine (H2 strain) is widely applied in prevention of hepatitis A epidemic in China and other countries now. It is essential to observe and confirm the vaccine immune efficacy, population antibody level and its persistent efficacy after mass immunization.

METHODSA total of 220 children with negative anti-HAV antibody (aged 1 - 3 years) were taken for follow-up assay to observe seroconversion and geometric mean titre (GMT) level 2 months, 12 months, 6 years, and 10 years after inoculation. Another survey sampled from subjects of different age groups (3, 6, 9, 15, 18, 25 and 35 years) to compare anti-HA antibody positive rate before and after inoculation performed 10 years previously. Epidemiological observations were taken for 10 years to evaluate the relationship between vaccine coverage and hepatitis A morbidity. Serum antibody to HAV was detected by enzyme linked immunoassay (ELISA, calibrated by WHO international reference) and ABBOTT Axsym HAVAB microparticle enzyme immunoassay.

RESULTSSeroconversion in follow-up assay 2 months and 10 years after inoculation was 98.6% and 80.2% respectively. For children, the vaccination anti-HA antibody positive rates were significantly different before and after 10 years, 7.69% cf 70.45% (aged 3 years) and 52.58% cf 71.78% (aged 18 years). When vaccine coverage rose from 57% to 74%, there were no any HA epidemics. When vaccine coverage reached 85%, there were no any HA cases. With vaccine coverage between 85% and 91%, there were no any HA cases in cohorts from the age of 1 year to 15 years during the 10 years.

CONCLUSIONSLive attenuated hepatitis A vaccine has an obvious long-term effectiveness in prevention and control of HA epidemics through mass vaccination.

Objective To evaluate the long-term immunogencity and effectiveness of live attenuated hepatitis A (HA) vaccine (H2 strain) after one dose injection, through a 15 years' follow up observation. Methods A total of 220 children with negative anti-HAV antibody (aged 1-3 y)were involved and followed up in Jiaojiang district, Taizhou city, Zhejiang province. Indicators would include seroconversion and geometric meantiter(GMT) levels after inoculation the vaccine with single dose at 2 m, 12 m, 6 years, 10 years and 15 years. Epidemiological observation was carried out within the 15 years to evaluate the relationship between vaccine coverage, the incidence of HA and the overall effectiveness. In the studied population, serum was tested by ELISA(calibrated by WHO international reference) and ABBOTT Axsym HAVAB mEIA. Results Seroconversion rates were found to be 98.6% and 81.3% after 2 months and 15 years of inoculation and slowly decreased. GMT level was 128 mIU/ml after 15 years, significantly higher than the required protective level of 20 mIU/ml,recommended by WHO experts. Effectiveness through the 15-year follow up program showed a significant correlation between vaccine coverage and incidence of HA in 1-15 years aged group (Kendall-Rank test, t =-0.931, P＜0.01). There was no HA case seen among the observed accumulated 236 413 person-year vaccines, compared to 4 HA cases discovered in the 27 206 personyear of the non-vaccinees. The overall protective rate reached 100%. Through a mass vaccination program on children, the whole population established an immune-defence to enable the incidence of HA decreased by 96.7%. Conclusion The long-term immunogencity and effectiveness of live attenuated hepatitis A vaccine (H2 strain) after one dose injection could last as long as 15 years.

BACKGROUNDReliable early prediction response to therapy and time-to-progression (TTP) remain an important goal of high-grade gliomas (HGGs) research. Proton magnetic resonance spectroscopy ((1)H-MRS) has been applied with variable success in clinical application, and we hypothesize that (1)H-MRS in predictive value should perform well as a marker of TTP in patients treated with radiotherapy (RT) after surgery.

METHODS(1)H-MRS was performed before surgery on 25 patients who had undergone resection of HGGs; then the ratios of lipid/creatine (Lip/Cr) and myo-inositol/creatine (mI/Cr) were determined in the solid tumor. RT response was classified as follows: complete resolution (CR), partial response (PR), stable disease (SD), and progressive disease (PD) by comparison of pre-treatment and post-radiotherapy scans. TTP was defined at the time to radiographic progression by MacDonald criteria. Correlation was evaluated between the ratios of Lip/Cr, mI/Cr and treatment response, TTP. The chi-square test and Pearson correlation test were used for data analyses.

RESULTSMultivariate analysis revealed that the prognostic value of spectroscopic variables was independent of age, sex, WHO histologic grade, extent of surgery, and Karnofsky score (KPS). The correlation between the ratios of lipid/Cr and TTP was significant (r = 0.894, P = 0.000), and between the ratios of mI/Cr and TTP was also significant (r = 0.891, P = 0.000). As predicted, RT response correlated significantly with TTP (r = 0.59, P = 0.002): median TTP was 49.9 days for patients with PD compared with 202.7 days for SD, 208.0 days for PR, and 234.5 days for CR.

CONCLUSIONThe ratios of Lip/Cr and mI/Cr of the solid tumor region before surgery could provide important information in predicting RT response and TTP in patients with HGGs treated by radiation alone after surgery.

BACKGROUNDPim-1 plays an important role in the apoptosis, proliferation, differentiation of cancer cells and progression of cancer. In this study we detected the expression of pim-1 mRNA in normal prostate, benign prostatic hyperplasia (BPH), and prostate cancer (PCa) and explored its diagnostic value for PCa.

METHODSThe prostate tissues were collected from 23 patients with PCa, 37 patients with BPH, and 3 healthy volunteers. Pim-1 mRNA expression levels in these samples were determined by the quantitative real-time PCR (QRT-PCR). The differences of expression were calculated based on a standard curve.

RESULTSThe ratio of pim-1 mRNA to beta-actin in the normal prostate, BPH, and PCa were 1.05 +/- 0.04, 2.57 +/- 0.74 and 4.45 +/-0.63, respectively. The differences among PCa, BPH and NT were significant (P < 0.05, respectively).

CONCLUSIONDetecting pim-1 mRNA expression by QRT-PCR provides a reliable metric for the diagnosis of PCa.
