Objective To determine associations between weight gain induced by antipsychotic and the polymorphisms of HTR2C gene -759C/T and -697G/C,histamine-1 receptor gene,leptine gene -2548G/A,and adiponectin gene +276G/T and +45T/G.Methods In the casematched study,85 patients who gained more than 7％ of their pre-drug body weight served as the study group and another 85 patients who gained less than 7％ of their pre-drug body weight served as the control group.The ligation diction reaction technique was used to analyze the frequencies of the -759C/T and -697G/C polymorphism of the HTR2C gene,-2548A/G polymorphism of leptin gene,+ 276G/T and + 45T/G polymorphism of adiponectin gene and glu349asp polymorphism of H1 receptor gene.Results The presence of the -759C allele,-697G allele,-2548A allele and + 276G allele was significantly higher in the study group than that in the control group (P ＜ 0.05 ).Conclusion The -759C/T and -697G/C polymorphisms of the promoter region of 5HT2C receptor gene,-2548A/G polymorphisms of leptin gene and + 276G/T polymorphisms of adiponectin gene may be associated with the antipsychotic induced weight gain.The glu349asp polymorphisms of histamine-1 receptor gene is not associated with antipsychotic induced weight gain.

Objective To analyze the expression of interleukin (IL)-31 in tuberculous pleural effusion,and to evaluate its diagnostic value of tuberculous effusion.Methods Seventy-one patients with pleural effusion were enrolled,including 40 cases of tuberculous pleural effusion and 31 cases of malignant pleural effusion.Luminex method was applied to detect the IL-31 expression in pleural effusion.IL-31 levels were compared using non-parametric Mann-WhitneyU test,and the receiver operator characteristic (ROC)curve was used to elvaluate the diagnostic value of IL-31 .Results IL-31 expression in tuberculous pleural effusion was significantly higher than that in malignant pleural effusion with statistical significance (529.4 ng/L vs 13.8 ng/L,U =62,P <0.01 ).Based on the level of IL-31 expression,area under the ROC curve was 0.95 with the optimum cut-off value of 67.5 ng/L.Thus,the sensitivity and specificity of IL-31 ≥67.5 ng/L for diagnosis of tuberculous pleurisy were 82.5 % (95 %CI :73.3% - 94.2%)and 100.0% (95 %CI :91 .4%-100.0%),respectively.Conclusion IL-31 is highly sensitive and specific for the diagnosis of tuberculous pleural effusion, which favors the differentiation of tuberculosis from malignance.

OBJECTIVETo study the value of iron metabolism indices, serum iron (SI), total iron blinding capacity (TIBC) and transferring (Tf), in thalassema.

METHODSThe serum samples from 9 children with silent alpha thalassema, 56 with standard alpha thalassema, 26 with HbH disease, 40 with beta+ thalassema, 56 with beta0 thalassema, 45 with iron deficiency anemia (IDA) and 70 healthy children were detected for SI, TIBC and Tf levels.

RESULTSThe SI level increased (p<0.01), while the TIBC level decreased significantly in the beta0 thalassema group compared with those in the other groups (p<0.05 or 0.01), but the Tf level was not different. The Tf level of both the silent alpha thalassema and the standard alpha thalassema groups was statistically lower than that of the healthy group (p<0.01), but the levels of SI and TIBC were similar to the healthy group. Though the SI level of the HbH disease group was similar to the healthy group, the TIBC and Tf levels were statistically lower (p<0.01).

CONCLUSIONSCompared with Tf, SI and TIBC are better indices for monitoring iron loading in children with thalassema. The increased SI level and decreased TIBC level are two indices for the diagnosis of beta(0) thalassema in children with cellule anaemia.

OBJECTIVE: To investigate the effect of ziprasidone and olanzapine on glucose and lipid metabolism in first-episode schizophrenia. METHODS: A total of 260 schizophrenics were assigned randomly to receive ziprasidone or olanzapine for 6 weeks. The weight was measured at baseline, week 2, 4 and 6. Fasting blood glucose (FBS), fasting insulin, high-density lipoprotein (HDL), total-cholesterol (TC) and triglycerides (TG) were measured at baseline and the end of 6-week treatment. Low-density lipoprotein (LDL) was measured in some patients at baseline and the end of 6-week treatment. Body mass index (BMI) and insulin resistance index (IRI) were counted. RESULTS: A total of 245 patients completed the trial, including 121 ziprasidone patients and 124 olanzapine patients. The average dose was 137.5 mg/d for ziprasidone and 19.5 mg/d for olanzapine. Patients treated with olanzapine had higher weight gain than those treated with ziprasidone [(4.55±3.37) kg vs (-0.83±2.05) kg, P<0.001]. After the treatment, FBS, fasting insulin, HDL, TC, TG, LDL and IRI levels were significantly increased in the olanzapine group (all P values<0.001 ). However, in the ziprasidone group, FBS decreased significantly and HDL and TG levels increased significantly after the 6-week treatment (all P values<0.05). The mean changes of FBS, fasting insulin, TC, TG, LDL and IRI were significantly different in the two groups (all P values<0.001). CONCLUSION Ziprasidone has less glucose and lipid metabolic effect for first-episode schizophrenia patients in short-term treatment. However, olanzapine induces weight gain and dysfunction of glucose and lipid metabolism significantly, which is associated with increased risk of complications. When the doctors choose antipsychotics in the clinic, they should consider the side effects of the medication.

OBJECTIVETo investigate the viral pathogens of acute lower respiratory tract infection (ALRTI) in hospitalized children from East Guangdong Province of China and the relationship of the pathogens with age and seasons.

METHODSThe nasopharyngeal aspirates samples obtained from 345 hospitalized children with ALRTI were investigated for respiratory syncytial virus (RSV), human bocavirus (HBoV), human metapneumovirus (hMPV), influenza virus types A and B, rhinovirus, parainfluenza virus types 1 and 3 and adenovirus by PCR.

RESULTSViral pathogens were detected in 178 patients (51.6%). RSV was the most frequent (19.3%). Novel viruses hMPV (3.2%) and HBoV (3.2%) were found. A highest detection rate (61.9%) of virus was found between January to March. The infants aged 1 to 6 months showed a higher detection rate (71.3%) of virus than the other age groups. The detection rate of viral pathogens was 72.6% in children with bronchiolitis, followed by asthmatic bronchitis (70.0%) and bronchial pneumonia (44.6%).

CONCLUSIONSRSV remained the leading viral pathogens in children with ALRTI in East Guangdong of China. Novel viruses HBoV and hMPV were also important pathogens. The detection rate of viral pathogens was associated with seasonal changes and age. Different respiratory infectious diseases had different viral detection rates, with highest detection rate in bronchiolitis cases.

Purpose: Neoadjuvant therapy modality can increase the operability rate and mitigate pathological risks in locally advanced cervical cancer, but treatment response varies widely. It remains unclear whether genetic alterations correlate with the response to neoadjuvant therapy and disease-free survival (DFS) in locally advanced cervical cancer. Materials and Methods: A total of 62 locally advanced cervical cancer (stage IB-IIA) patients who received neoadjuvant chemoradiation plus radical hysterectomy were retrospectively analyzed. Patients’ tumor biopsy samples were comprehensively profiled using targeted next generation sequencing. Pathologic response to neoadjuvant treatment and DFS were evaluated against the association with genomic traits. Results: Genetic alterations of PIK3CA were most frequent (37%), comparable to that of Caucasian populations from The Cancer Genome Atlas. The mutation frequency of genes including TERT, POLD1, NOS2, and FGFR3 was significantly higher in Chinese patients whereas RPTOR, EGFR, and TP53 were underrepresented in comparison to Caucasians. Germline mutations were identified in 21% (13/62) of the cohort and more than half (57%) had mutations in DNA damage repair genes, including BRCA1/2, TP53 and PALB2. Importantly, high tumor mutation burden, TP53 polymorphism (rs1042522), and KEAP1 mutations were found to be associated with poor pathologic response to neoadjuvant chemoradiation treatment. KEAP1 mutations, PIK3CA-SOX2 co-amplification, TERC copy number gain, and TYMS polymorphism correlated with an increased risk of disease relapse. Conclusion We report the genomic profile of locally advanced cervical cancer patients and the distinction between Asian and Caucasian cohorts. Our findings highlight genomic traits associated with unfavorable neoadjuvant chemoradiation response and a higher risk of early disease recurrence.

OBJECTIVETo explore the effect of prostatectomy on nocturia in patients with benign prostatic hyperplasia (BPH).

METHODSThe data of patients who had received prostatectomy for BPH between June 2006 and December 2007 were collected. Nocturia severity was assessed preoperatively and 3 to 6 months after prostatectomy by the number of nocturia events, the time from falling sleep to the first awakening to void (hours of undisturbed sleep, HUS), the score of the nocturia quality of life (N-QOL) questionnaire, the International Prostatic Symptom Score (IPSS) and the quality of life (QOL) score.

RESULTSOne hundred and twenty five cases were included. Of them, 73 patients finished the follow-up completely. There were 62 patients whose number of nocturia events before the operation was equal or more than 2. The data from these 62 patients were analyzed. Of them, 56 patients underwent transurethral resection of prostate, the remaining 11 patients suprapubic prostatectomy. Significant improvement (P < 0.01) was noted in all the following parameters after treatment: the number of nocturia events decreased from 4.2 ± 2.4 to 2.2 ± 1.0, HUS increased from (1.8 ± 0.7) h to (3.0 ± 1.4) h, N-QOL score raised from 30 ± 10 to 40 ± 7, IPSS decreased from 23 ± 5 to 8 ± 5, and QOL score fell down from 4.4 ± 0.7 to 1.5 ± 1.0.

CONCLUSIONThe prostatectomy can markedly improve the symptoms of nocturia, sleep and life quality in the BPH patients who accompanied with nocturia.

OBJECTIVETo evaluate the reliability of different hepatitis E diagnosis reagent tests on the acute hepatitis E.

METHODSThree acute hepatitis E diagnosis tests, E2-IgM (Wantai, China), GL-IgM and GL-IgG (Genelabs, Singapore) were compared for their reliability in a sera panel composed by 273 healthy individuals and 525 hepatitis.

RESULTSThe specificity of E2-IgM on the diagnosis of acute hepatitis E was 100.0%, it was significantly higher than GL-IgM (96.7%) and GL-IgG (85.4%). The sensitivity of E2-IgM and GL-IgG were 97.9% and 93.8% respectively, both significantly higher than GL-IgM (72.9%). Among 65 acute hepatitis cases being positive on GL-IgM test but negative on E2-IgM, 58 (89.2%) cases were found to be positive with anti-hepatitis A virus IgM, it indicated that the GL-IgM test might be interfered by other IgM antibodies on serum.

CONCLUSIONE2-IgM is a good test for the diagnosis of acute hepatitis E.
