Objective:To investigate the effect of pidotimod on the expressions of IL-2 and IL-10 of patients with genital herpes(GH) and obverse its curative effect and quality of life of the patients.Mehtods:45 cases of outpatients with GH were selected as experimental group wich were given pidotimod orally 0.8g per day for 3 months.Observe the curative effect and value the quality of life before and 3 months after and 6 months after the treatment respectively.Detect the change of the expressions of IL-2 and IL-10 of the blood plasma of the GH patients.Select 30 healthy people as control group.Results:The recurrence rate of the experimental group during 1-3 month,4-6 month,7-9 month after treatment were 60.0%、42.2%and 22.2%respectively.The scores of quality of life and the total evaluation of quality of life itself (G1) and health condition(G4) at 3 and 6 month after treatment rising significantly than before treatment,and it is more obviously at 6 months after treatment than 3 months after treatment.Before treatment,the level of IL-2 of experimental group is significantly lower than that of control group,while the level of IL-10 of the experimental group is significantly higher than that of control group.3 and 6 months after treatment,the level of IL-2 rising significantly,while the level of IL- 10 reducing significantly.The change is more obviously at 6 months after treatment than 3 month after treatment either in the IL-2 rising or the IL-10 reducing.Conclusion:There is cellular immune function disorder in the GH patients.Pidotimod has a certain curative effect on the GH patients.It can reduce the recurrence rate of GH and improve the quality of life of the patients.Maybe it can enhance the cellular immune function of the body through rising the level of IL-2 and reducing the level of IL-10.

Objective To investigate the regulation effect of hepatocyte nuclear factor (HNF) 1α on the gene expression profile and the signal pathways in HuH7 cells.Methods The expression of HNF1α was increased or decreased in HuH7 cells by Lenti-virus carrying HNF1α or shHNF1α.The expression profile of the cells after treated was examined by microarray technology.The difference expressed gene regulated by HNF1α were screened and the pathway was analyzed with DAVID software and related analysis system.The regulation effect of HNF1α on transforming growth factor (TGF)β signal pathway was detected by reporter gene test and the regulation role of HNF1α on related genes of TGFβ signal pathway was determined by real-time polymerase chain reaction (PCR) and Western blotting assay.Results The expression of HNF1α in HuH7 cells was significantly up-regulated by Lenti-virus carrying HNF1α gene (Lenti-HNF1α) and which was down regulated by Lenti-virus with shHNF1α gene (LentishHNF1 α).Expression profile analysis revealed that 339 genes were positively up regulated two times by HNF1α and 325 genes were negatively down regulated two times.Signal pathway analysis revealed that HNF1α regulated drug metabolism,biosynthesis of unsaturated fatty acids and glycolysis/gluconeogenesis metabolism signal pathways.Moreover,it also involved in the regulation of TGFβ、nuclear factor (NF)-κB and p53 tumor-related signal pathways.Furthermore,Luciferase reportor gene experiment indicated that up-regulated HNF1α could inhibit the activation of TGFβ signal pathway.And the results of real-time PCR and Western blotting verified that up-regulated HNF1α could inhibit TGFβ signal pathway related gene c-myc and TGFβ1 and then inhibited the activation of TGFβ signal pathway.Conclusion HNF1α broadly affects the gene expression profile and the tumor genesis and development related signal pathways in HuH7 cells,furthermore,HNF1α can inhibit the activation of TGFβ signal pathway.

Objective To investigate the safety and feasibility of endovascular stent angioplasty in treating symptomatic stenosis of middle cerebral artery.Methods Endovascular angioplasty with coronary stents was performed in 27 patients with symptomatic stenosis of middle cerebral artery.The clinical results were reviewed and analyzed.Results Of the total 27 patients,successful placement of the coronary stents Was achieved in 24.Angiography immediately after the procedure showed that the stenotic degree of the diseased artery was markedly decreased from preoperative (80±19)%to postoperative (8±4)%,the improvement was very obvious.Percutaneous transcatheter angioplasty had to be employed in two cases because of the failure of stent placement.A mean follow-up period of 18 months was carried out.During the following up period no transient cerebral ischemia attack occurred in 25 patients and no newly-developed cerebral infarction in region fed by the responsible vessels occurred either.Re=irrigation cerebral hemorrhage was seen in one patient,which occurred three hours after the placement of the stent.In one case the placed stent fell off and immigrated into the siphon of internal carotid artery,and the displaced stent Was took out later with a catching apparatus.In another case re-stenosis occurred six months after the stenting.Conclusion Percutaneous endovaacular stent angioplasty is a safe and effective treatment for symptomatic stenosis of middle cerebral artery,although its long-term results need to be further evaluated.

ObjectiveTo evaluate the effects of diagnosis of cervical insufficiency and different management on pregnancy outcomes.MethodsFrom June 2004 to May 2010, a retrospective analysis was carried out on 554 patients with cervical insufficiency in nine hospitals in Guangdong Province, China. The patients were divided into two groups, the cervical cerclage surgical treatment group (surgical group,n=357) and the expectant treatment group (n=197). These patients were then re-diagnosed according to the unified diagnostic criteria by the American College of Obstetricians and Gynecologists (2014), and divided into the definite diagnosis group (n=425) and the indefinite diagnosis group (n=129). The two independent samplest-test andChi-square test were used to compare pregnancy outcomes between the definite and indefinite diagnosis groups, and the different treatment groups.ResultsThe full-term delivery rate in the surgical group was significantly higher than that in the expectant treatment group [40.3% (144/357) vs 23.4% (46/197),χ2=16.254, P=0.000], and the late abortion rate was lower in the surgical group than in the expectant treatment group [22.4%(80/357) vs 40.1% (79/197),χ2=19.419,P=0.000]. In women with a definite diagnosis of cervical insufficiency, full-term delivery rate [44.7% (117/262) vs 20.9% (34/163),χ2=24.844,P=0.000], and newborn body weight were significantly higher in the surgical group [(2 664.3±762.2) vs (2 416.9±845.0) g,t=1.160,P=0.014] than in the expectant treatment group and the late abortion rate was significantly lower [21.4% (56/262) vs 41.1% (67/163),χ2=19.021,P=0.000]. Cervical cerclage in the indefinite diagnosis group did not resulted in raising the full-term delivery rate [28.4% (27/95) vs 35.3% (12/34),χ2=0.561], preterm delivery rate [46.3%(44/95) vs 29.4% (10/34),χ2=2.940], late abortion rate [25.3% (24/95) vs 35.3% (12/34),χ2=1.252] and newborn body weight [(2 526.5±761.8) vs (2 683.4±725.8) g,t=0.004] compared with expectant treatment group (allP>0.05). Pregnancy outcomes in the surgical treatment group in relation to twin pregnancies were not significantly different in the≥28 weeks delivery rate [81.4% (37/46) vs 69.2% (18/26),χ2=1.156], late abortion rate [19.6% (9/46) vs 30.8% (8/26),χ2=1.156] and newborn birth weight [(2 003.2±621.0) vs (1 807.5±609.4) g, t=0.057] compared with those in the expectant treatment group (allP>0.05).ConclusionsIn accordance with the diagnostic criteria for cervical insufficiency and indications for cervical cerclage in surgical cases, cervical cerclage can effectively improve pregnancy outcome. But cervical cerclage is not recommended in twin pregnancies with cervical insufficiency.

OBJECTIVETo investigate the relationship between polymorphism of N-acetyltransferase (NAT2) gene and genetic susceptibility to laryngeal carcinoma.

METHODSA case-control study on 62 laryngeal carcinoma patients and 56 controls was conducted. NAT2 alleles were differentiated by polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) methods using originally created PCR primers and genomic DNA extracted from peripheral white blood cells. Genetic risk for NAT2 genotype was analyzed by smoking index (SI, cigarettes smoked per day x years of smoking).

RESULTSThe frequency of NAT2 slow genotype was 80.6% in patients with laryngeal carcinoma and 60.7% in the controls, the difference of which was statistically significant (chi(2) = 5.70, P = 0.017). The odds ratios were 2.70 (95% CI 1.19 approximately 6.11). Among the individuals with NAT2 slow genotype at high level of cigarette smoking, there was a significantly higher risk of 5.64 (95% CI 1.77 approximately 17.92), while those at low level were considered the reference group (OR 1.38, 95% CI 0.42 approximately 4.52).

CONCLUSIONNAT2 slow genotype increases the risk of susceptibility to laryngeal carcinoma. The combined effect of NAT2 slow genotype and exposure to smoking is observed during the development of laryngeal cancer.
