Objective To study the role of cell apoptosis during the chemotherapy of human gliocytoma in order to get effective suvilliance on the effect of chemotherapy. Methods Gliocytoma cells were isolated and cultured from 40 human gliocytoma samples. Mitochondrial membrance potential (MMP), cell cycle, the level of Bcl-2 and Bax were detected by flow cytometry (FCM) at 24, 48, 72 hours respectively of incubation with Lomustine (CCNU) and Teniposide (VM-26), and the trends were also analysed. Results MMP decreased greatly, the apoptosis part in the cell cycle ananlysis increase, the expression level of Bcl-2 decreased, and that of Bax increase rapidly, while the Bcl-2/Bax ratio decreased. Conclusions CCNU and VM-26 have singnificant effect in gliocytoma chemotherapy on inducing gliocytoma cell apoptosis. VM-26 has more stronger effect on the cell cycle. MMP is the most sensitive and the fastest index in apoptosis detection.

Two isomers of nitrochlorobenzene (o-, and p-NCB) were treated by a Pd/Fe catalyst in aqueous solutions through catalytic amination and dechlorination. Nitrochlorobenzenes are rapidly converted to form chloroanilines (CAN) first through an amination process, and then rapidly dechlorinated to become aniline (AN) and Cl(-), without the involvement of any other intermediate reaction products. The amination and dechlorination reaction are believed to take place predominantly on the surface site of the Pd/Fe catalysts. The dechlorination rate of the reductive degradation of the two isomers of nitrochlorobenzene (o-, and p-NCB) in the presence of Pd/Fe as a catalyst was measured experimentally. In all cases, the reaction rate constants were found to increase with the decrease in the Gibbs free energy (correlation with the activation energy) of NCBs formation; the activation energy of each dechlorination reaction was measured to be 95.83 and 77.05 kJ/mol, respectively for o- and p-NCB. The results demonstrated that p-NCBs were reduced more easily than o-NCBs.

Objective To construct a luciferase reporter plasmid containing interferon regulatory factor 3(IRF-3)human gene promoter and to evaluate promoter activity in human embryonic kidney(HEK)-293 cells.Methods The 1 000 bp fragment was amplified by PCR with human genomic DNA as a template and was directionally cloned into pGL3-basic multiple cloning sites to construct the luciferase repor-ter plasmid pGL3-pIRF-3.Transfection of HEK-293 cells with the promoter-driven lucife-rase construct was performed to induce lucife-rase gene expression and calculate the relative luciferase activity unit(RLU).Promoter sequence of 1 000 bp upstream of transcription initiation site of IRF-3 was analyzed by using Promoter 2.0 Prediction software.Results DNA sequencing and restriction endonuclease analysis verified the successful construction of the plasmid pGL3-pIRF-3.This IRF-3 promoter exhibited a strong promoter activity with an increase of 42.2-fold of RLU in HEK-293 cells when compared with pGL-3 basic vector.The transfection experiment confirmed that the levels of its activation were significantly higher than that in controls in HEK-293 cells.Function analysis of IRF-3 promoter disclosed seve-ral GATA-1 and specific protein 1(Sp1) sites and E2F in minimal promoter region.Conclusion The plasmid pGL3-pIRF-3 promoter is successfully constructed and has a strong basal promoter activity in HEK-293 cells.

Objective To study the clinical significance of P - selection expression in children with viral encephalitis and the correlation between this expression and the cerebral infarction with critical viral encephalitis. Methods Flow cytometric was employed to detect the expression of P- selection on the surface of platelet membrane in 44 children with viral encephalitis(20 light patients and 24 critical patients) and 20 healthy control children. The area of the cerebral infarction was determined by computed tomographic scan in 20 patients with critical viral encephalitis. The correlation between the two variables was analyzed. Results The expressions of P - selection on the surface of platelet membrane on less than 5 days and on 2 weeks after the onset of viral encephalitis were significantly higher in critical patients than those in normal control children and light patients( P

OBJECTIVETo investigate the association of A260G and A386G polymorphisms of the DAZL gene with male infertility caused by oligozoospermia or azoospermia.
METHODSWe searched the PubMed, Science Direct, Wiley Online Library, CNKI, VIP, and CDDB databases up to November 30, 2013 for case-control studies evaluating the relationship of SNP260 and SNP386 polymorphisms of the DAZL gene with male infertility, and meanwhile conducted manual sourcing of the references in the identified studies and relevant articles. Two reviewers independently screened the title, abstract and keywords of each article retrieved. The StataSE12. 0 software was used for meta-analysis and other statistical analyses.
RESULTSTotally, 13 case-control studies were included (10 about A260G and 11 about A386G), involving 2 715 infertile patients (2 500 with oligozoospermia or azoospermia) and 1 835 normozoospermic men. DAZL A260G showed no statistical significance in the allele, dominant, recessive, co-dominant, or super-dominant gene model (P >0. 05). DAZL A386G exhibited a strong correlation with oligozoospermia or azoospermia in Asians in the allele gene model (OR = 0. 15, 95% CI 0.07 -0.34, P <0.05), dominant gene model (OR =0. 16, 95% CI 0.07 - 0. 35, P <0.05), co-dominant gene model (AA/AG) (OR = 0. 15, 95% CI 0. 06 - 0. 33, P < 0. 05), and super-dominant gene model (OR = 0. 15 (95% CI 0.06 - 0.33, P <0.05) , and so did it in Chinese in the four gene models ( OR = 0. 11, 95% CI 0.04 - 0. 28, P <0.05; OR =0. 11, 95% CI 0.04 - 0.28, P<0.05; OR = 0.09, 95% CI 0.03 - 0.26, P<0.05; OR = 0.09, 95% CI 0.03 - 0.26, P< 0.05).
CONCLUSIONOur study manifested that the DAZL polymorphism A386G, but not A260G, was correlated with reduced sper- matogenesis or sperm count specifically in Chinese males. More high-quality trials are required for a deeper insight into the exact relationship of DAZL A260G and A386G polymorphisms with oligozoospermia- or azoospermia-induced male infertility.

OBJECTIVE:To explore the therapeutic effect of early use of alprostadil and the effects on PTX-3,renal function and stability of carotid plaque in patients with acute cerebral infarction. METHODS:93 patients with acute cerebral infarction in our hospital from Aug. 2011 to Aug. 2015 were selected,and divided into observation group(47 cases,2 case withdrew from the test and 45 cases completed the test)and control group(46 cases,1 case withdrew from the test and 45 cases completed the test) by odd and even number of registration order. Control group was given Citicoline sodium injection 0.5 g + Extract of ginkgo biloba leaves injection 20 ml added into Sodium chloride injection(NS)250 ml,ivgtt,qd;observation group was additionally given Al-prostadil injection 20 μg added to NS 250 ml,ivgtt,qd. They were treated for 2 weeks. Clinical efficacy,and the differences of PTX-3,blood urea nitrogen(BUN),serum creatinine(SCr),24 h urinary protein(Upro),stability of carotid plaque before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group(91.1%)was higher than control group(73.3%),the difference was statistically significant(P<0.05). There was no statisti-cal significance in PTX-3,BUN,SCr,24 h Upro between 2 groups before treatment (P>0.05). After treatment,PTX-3,BUN, SCr,24 h Upro in 2 groups decreased,and observation group was lower than control group;stability of carotid plaque in observa-tion group(100.0%)was higher than control group(64.0%),the differences were no statistically significant(P<0.05). The ad-verse reactions in 2 groups relieved themselves with no special treatment,and with no statistical significant(P>0.05). CONCLU-SIONS:The early use of alprostadil is effective for acate cerebral in farction,and can obviously reduce PTX-3 and improve renal functions,increase stability of carotid plaque with good safety.
