Objective To evaluate the effects of ginsenoside Rg3 combined with XELDX regimen on advanced carcinoma of stomach.Methods Totally 93 postoperative patients with advanced gastric cancer were randomly divided into two groups:control group(n ＝ 53) who received only XELDX regimen,and study group (n＝ 40) who were treated with ginsenoside Rg3 + XELDX.The objective response rate,KPS score and serum VEGF levels in the two groups were detected.Results (1) Before treatment,treatment group and control group showed that serum VEGF levels were (387.63±159.74) μg/L and (378.56± 169.36) μg/L,respectively (P＜0.05).After 8 weeks of treatment,serum VEGF of the treatment group decreased to (207.74 ± 115.71) μg/L,the level of the control group VEGF decreased to (246.53 ±107.63) μg/L(P＜0.05).(2) The efficacy rate was 57.5％ (23/40) in treatment group and 45.3％(24/53) in the control group (P＞0.05).(3) KPS score increasing rate was higher in treatment group (65.0％) than in control group (39.6％)(x2＝5.87,P＜0.05).Conclusions Ginsenoside Rg3 combined with chemotherapy in advanced gastric cancer patients can reduce serum VEGF levels and improve the quality of life of patients.

Objective To explore the features and neural generators of the events related potentials ( ERP) component N400, elicited by congruent and incongruent ending sentences, in first episode schizophrenia patients. Methods N400 was elicited by 76 congruent (31) or incongruent (45) ending Chinese sentences paradigm, and recorded by WJ-1 ERP instruments in 56 first episode schizophrenia. The neural generators of N400 different wave in 105 -615 ms time windows were analyzed by Brain Electrical Activity Mapping software. Results① The N400 latencies were significantly longer and amplitudes significantly higher in incongruent conditions than in congruent conditions in first episode schizophrenia (P < 0.05 or P <0.01).② N400 elicited by Chinese sentences distributed on frontal, parietal, occipital and temporal regions, and had a clear waveform. ③ The main brain areas activated by N400 were frontal areas in 345 -405 ms time windows, and central areas in 420 - 570 ms time windows. Conclusion N400 elicited by Chinese sentences are multi-generated in first episode schizophrenia, especially in frontal area.

ObjectiveTo investigate the influence of Mycobacterium tuberculosis (MTB) co-infection and other factors on the HIV replication level in antiretroviral treatment na(i)ve patients.MethodsSix hundred TB patients and 465 HIV infectors were recruited between April 2010 and September 2010.TB coinfections were diagnosed in HIV infected cases with chest X-ray,checking TB in sputum with anti-acid staining and culture of the sputum,histopatholo diagnosis and clinical diagnosis.HIV infections were screened in TB patients with the 3rd generation ELISA antibody test.Sixty-one antiretroviral treatment na(i)ve HIV/TB co-infectors and 34 HIV infectors with CD4 T cell count below 350 cells/μl were included in this study.Information about the demography,epidemiology and results of clinical diagnostic tests of HIV and TB was collected through pathography and questionnaires from all participants.HIV viral load were detected with COBAS AmpliPrep/COBAS TaqMan(R) System of Roche Company.ResultsThe viral load of HIV/TB co-infectors was (5.05±0.93) lg copies/ml,while the viral load of HIV infectors was (5.06±0.76) lg copies/ml,after control of age,race,marital status,education,route of HIV infection,HIV clade and CD4 T cell count,there was no significant difference between the two groups (P=0.94).CRF01_AE HIV-1 infection was associated with higher HIV viral load compared with non CRF01_AE (OR=8.07,95％ CI 1.07-61.20,P=0.04).ConclusionNo obvious effect of MTB co-infection on HIV replication level of HIV infected cases with relatively low CD4 T cell count in Guangxi region,while the CRF01_AE HIV infected individuals showed higher viral load,we should raise concern on the monitoring and treatment on this population.

OBJECTIVE: To assess the association of single nucleotide polymorphisms (SNP) of aquaporin 7 ( AQP7) and aquaporin 9 ( AQP9) genes and type 2 diabetes mellitus (T2DM) among ethnic Han Chinese population. METHODS: A case-control study involving 1194 subjects with T2DM and 1274 non-diabetic mellitus (NDM) subjects were enrolled. Genotypes of three SNPs (rs3758269 of AQP7 gene, rs16939881 and rs57139208 of AQP9 gene) were determined by using a MassArray method. The association of the three SNPs with T2DM was assess, and the correlation of glucose and lipid metabolism parameters with various SNP genotypes in the NDM group was analyzed. RESULTS: The allelic and genotypic frequencies of the three SNPs did not differ significantly between the two groups (P>0.05). Nor was there significant difference between the two groups with different genetic models (P>0.05). No significant association of genotypes of AQP7 gene rs3758269, AQP9 gene rs16939881 and rs57139208 with glucose and lipid metabolism parameters were observed in the NDM group (P>0.05). CONCLUSION The rs3758269 in AQP7 gene and rs16939881 and rs57139208 in AQP9 gene are not associated with the genetic susceptibility of T2DM among ethnic Han Chinese population.
