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.

0.05). However, a significant higher percentage of CD3+CD25+ T cells was found in stable liver transplantation group as compared to healthy group ( P0.05). There was not found no regular change of serum cytokine s (IL-6, TN F-?) and adhesion molecules (ICAM-1, P-selectin) in 6 liver transplanted patien ts during post-operation from day 1 to day 30, indicating that was associated wi th the different status of patients before or after transplantation. CONCLUSIONS: Our data suggesting that increased levels of ICAM-1 and P-selectin, appears to participate in the processing of immunoregulation to transplanted livers, whereas elevated concentrations of IL-6 appear to be involv ed in the repair of the injury induced by TNF-? in allo-transplanted livers.

To compare the chemical components of supercritical extracts from Herba Ephedrae and honey-prepared Herba Ephedrae. Volatile oils were extracted from Herba Ephedrae and honey-prepared Herba Ephedrae by supercritical CO 2 extraction and then identified by the combination of gas chromatography and mass spectrometry (GC-MS). Twenty kinds of components such as diethylsulfate obtained from Herba Ephedrae were not found in honey-prepared Herba Ephedrae and twelve different components such as hydroxymethylfurfural were obtained from honey-prepared Herba Ephedrae. The extraction rate of volatile oils was 2.1% in herba ephedrae and 1.0% in honey-prepared Herba Ephedrae. [ Conclusion]The components of supercritical extractions from Herba Ephedrae differ from those in honey-prepared Herba Ephedrae.

Objective To investigate the expression of engulfment and cell motility protein 1 (ELMO1) in hepatocellular carcinoma(HCC) and its effects on cell migration.Methods The expression of ELMO1 in HCC cell lines and HCC tissues was assessed by Western blot.We used transient transfection with an ELMO1 expressing vector to over-express ELMO1 protein in SK-HEP-1 cells.Over-expression of ELMO1 was confirmed by Western blot.siRNAs specific to ELMO1 (ELMO1 siRNA) were used to knockdown ELMO1 expression.Rho Family Small GTPase Activation Assay, Western blots, transwell assay were used to determine the migration potential of cells.Student's test was employed for statistical analysis.Results The expression of ELMO1 protein was obviously up-regulated in HCC tissues and cell lines (P<0.05).Over-expression of ELMO1 promoted cell migration in SK-HEP-1 cells, while knock-down of ELMO1 showed the opposite effect.Conclusion ELMO1 up-regulation significantly correlates with cell migration in hepatocellular carcinoma.

OBJECTIVE To investigate the deafness-related gene mutation frequency and hotspots in patients of Fuzhou city with non-syndromic hearing loss (NSHL). METHODS Peripheral blood samples were obtained from 88 cases of patients with hearing loss after clinical history inquiry and clinical examination. Their genomic DNA was extracted from peripheral blood by extraction kits to undergo polymerase chain reaction, traditional capillary electrophoresis sequencing and High-throughput sequencing so as to detect the mutations of deafness-related gene. RESULTS Among the 88 patients with NSHL, the gene mutation frequency was 34.09%.In the patients, 14 cases had mitochondrial 12 S rRNA mutations, six cases had GJB2 gene mutations and three cases had SLC26A4 mutations, two cases had MYO15A mutations, the other five cases had MYO7A, OTOF, TECTA, TMC1 and ILDR1 gene mutation respectively. CONCLUSION Among the 88 patients with NSHL, the most frequent mutation causing hereditary deadness was mutation in mitochondrial 12 S rRNA, followed by GJB2 and SLC26A4, The other genes such as MYO7A, OTOF, TECTA, TMC1 and ILDR1 gene were infrequent. The study could provide theoretical reference in genetic diagnosis, prevention and cure of hearing loss.

Objective To explore the way of contrast-enhanced ultrasound(CEUS)and quantitative analysis technology to assess testicular microvascular ischemia-reperfusion inj ury.Methods Twenty-four healthy adult rabbits were randomly divided into the control group and the microvascular mild,moderate, serve ischemic inj ury group (group Ⅰ,including group Ⅰ1 ,Ⅰ2 ,Ⅰ3 ).The spermatic cord of the control group were threaded but not ligated.The group Ⅰ1 ,Ⅰ2 ,Ⅰ3 were reperfused 2 h after 2 h,4 h,6 h complete testicular ischemia respectively.The ultrasound contrast angiographic parameters of each group were analyzed by the quantitative analysis techniques,including peak intensity(PI),time to peak(TP),slope,mean transmit time(MTT),DT/2 and area.The levels of plasma vWF,NO and ET-1 were tested after the CEUS. The pathological changes of the ipsilateral testicular were observed by the HE and immunohistochemical staining.Statistical analysis was performed by SPSS 13.0 software.Results Preoperativeiy,each parameter of the experimental group and the control group showed no statistical significance (P > 0.05 ). Postoperatively,the PI,slope,area of the group Ⅰ1 increased significantly,while the TP,MTT were prolonged(P <0.05).Contrast time-intensity curve was significantly higher peak and retrusion.The groupⅠ2's PI,slope,area increased further,DT/2 was significantly prolonged,but TP significantly reduced (P <0.05).The contrast curve significantly increased,forward and decreased slowly.The contrast curves of the group Ⅰ3 was approximate a straight line.The vWF,NO,ET-1 levels of each experimental group were significantly higher than those in control group (P <0.05),among them,the levels of group Ⅰ2 were the highest (P <0.05 ).With the aggravation of ischemia,the testicular capillaries expansion,erythrocyte sedimentation,leakage,infiltration of inflammatory cells,MMP-9 expression in vascular basement membrane gradually increased.Conclusions The CEUS and quantitative analysis techniques can effectively evaluate testicular microvascular inj ury.
