AIM:To explore whether the inhibitory effect of triptolide on IL-1? production by PBMC is associated with IL-1? gene polymorphisms.METHODS:IL-1? gene polymorphism was analyzed in 31 healthy volunteers.From genomic DNA,the C-T polymorphism at IL-1?-511 was typed by PCR-RFLP.Meanwhile the IL-1? was also measured in the supernatants of the cultured and stimulated peripheral blood mononuclear cells(PBMC)by ELISA.RESULTS:After LPS stimulation in PBMC cultures of healthy subjects,the secretion levels of IL-1? in 9 volunteers who carried IL-1?-511 T/T genotype were higher than in volunteers who are not T/T genotype(P0.05).CONCLUSION:The gene polymorphism at IL-1?-511 was related to the production of IL-1?,and the inhibitory effect of triptolide on the production of IL-1? was different in C/C,C/T,T/T genotype of IL-1?-511,which may be one of the reasons for the phenomenon that people respond differently to triptolide.

Objective To compare the different types of physical artificial liver support system(ALSS) applied in the treatment of patients with early stage of chronic severe hepatitis in order to evaluate the therapeutic effect and look for the most effective one.Methods One hundred and twenty patients of chronic severe hepatitis B in early stage were randomly divided into 4 groups(each n=30).The patients in group 1 were treated by 3 000 ml plasma exchange;in group 2,by 2 000 ml plasma exchange combined with plasma adsorption for 2 hours;in group 3,only by plasma adsorption for 3 hours and in group 4,by molecular adsorbent re-circulating system(MARS).The observation time lasted for 2 weeks and the therapy twice a week,the interval between two times of treatment being 2-3 days.The improvement of symptoms,the fade away and rebound of icterus,the changes of albumin and prothrombin activity(PTA),side effects(anaphylaxis,hepatic encephalopathy,edema of conjunctiva,burp,fluid and electrolyte balance failure,changes of blood routine test and ammonia level,etc) were compared before and after the treatment.Results The symptoms of 27 cases in group 1 were improved,the rate of decrease of total bilirubin(TBil) of group 1 was 51.8% and the range of icterus rebound was 14.4% to 46.7% with comparatively more side effects.The symptoms of 24 cases of group 2 were improved,the rate of decrease of TBil in group 2 was 62.2% and the range of icterus rebound was 2.8% to 28.5% with comparatively less side effects.The symptoms of 16 cases of group 3 were improved,the rate of decrease of TBil in group 3 was 38.8% and the range of icterus rebound was 2.8% to 6.8% with less side effects.The symptoms of 26 cases of group 4 were improved,the rate of decrease of TBil in group 4 was 60.1% and the range of icterus rebound was 7.8% to 27.4% with comparatively more side effects,moreover the cost was higher than that in the other groups.Conclusion The method of reduced plasma exchange combined with plasma adsorption with macroporous resin used to cure chronic severe hepatitis at early stage has the characteristic of good effects for the fade away of icterus,little rebound of icterus and side effects.It is the reasonable method of artificial liver to cure the early stage of chronic severe hepatitis.

Objective To investigate the clinical efficacy of selenium-enriched garlic on patients with oligoasthenospermia.Methods From October 2012 to August 2013,160 patients with oligoasthenospermia were randomly divided into two groups.Treatment measurements for 80 patients in the control group included oral treatment of Shengjing capsules 1.6 g/time Tid,Vit-E soft capsules 100 mg/time Tid,and took Vit-B 0.2 g/time Tid,for three months.Treatment measurements for 80 patients in the treatment group included oral treatment of selenium-enriched garlic in addition to all the above,for three months.We observed the changes of the semen quality indexes (including semen volume,sperm density,motility,survival rate,etc.) of two groups before and after treatment.Results Sperm quality was improved after treatment in both groups.All indices in the treatment group were significantly higher than those in the control group (P ＜ 0.05).Conclusions For patients with male infertility caused by oligoasthenospermia,The use of combination of selenium-enriched garlic and Shengjing capsules can improve the quality of sperm.

Objective To assess the effect of magnetic resonance imaging (MRI) on preoperative staging of endometrial carcinoma and depth of myometrial invasion. Methods Fifty-six patients with endometrial carcinoma were underwent conventional and contrast-enhanced MR scan. The results of pathology , MRI examinations of preoperative staging and depth of myometrial invasion were assessed and compared. Results The accurate rate of MRI diagnosis in preoperative staging diagnosis was 82.1% (46/56) and the consistency check as Kappa was 0.771 (P < 0.001). Conclusions MRI may be a good diagnostic tool with high sensitivity and specificity for assessing myometrial invasion and detecting tumour extension and should be considered as a routine part of the preoperative assessment in all patients with endometrial carcinoma.

Objective To investigate the expression level of peripheral blood mononuclear cell(PBMC)human leucocyte anti-gen G(HLA-G)in patients with hepatocellular carcinoma(HCC).Methods The HLA-G mRNA in PBMC from 44 patients with HCC,21 patients with liver cirrhosis and 40 healthy subjects were measured by reverse transcription real time fluores-cent relative quantitative PCR.Results HLA-G mRNA expression level were 1.71±0.39,1.05±0.38 and 1.01±0.47 in HCC group,liver cirrhosis group and healthy control group respectively.HCC group was higher than the other two groups, the difference was statistically significant (F=33.657,P<0.001).The survival rate of HCC patients in HLA-G mRNA high-expression group was lower than HLA-G mRNA low-expression group,the difference was statistically significant (χ2=5.972,P=0.015).Conclusion PBMC HLA-G mRNA in HCC was closely correlated with tumorigenesis.It can proviede a novel diagnosis and research tool for HCC.

AIM: To explore whether the inhibitory effect of triptolide on IL - 1β production by PBMC is asso ciated with IL - 1β gene polymorphisms. METHODS: IL - 1β gene polymorphism was analyzed in 31 healthy volunteers. From genomic DNA, the C - T polymorphism at IL - 1 β - 511 was typed by PCR - RFLP. Meanwhile the IL - 1 β was also measured in the supernatants of the cultured and stimulated peripheral blood mononuclear cells (PBMC) by ELISA. RE SULTS: After LPS stimulation in PBMC cultures of healthy subjects, the secretion levels of IL - 1 β in 9 volunteers who carried IL - 1β -511 T/T genotype were higher than in volunteers who are not T/T genotype (P ＜0.05). Triptolide sup pressed the production of IL - 1β significantly in LPS - treated human PBMC carried C/C and C/T genotype ( P ＜ 0.05 ), but this significant inhibitory effect of triptolide was not seen in T/T genotype ( P ＞ 0.05 ). CONCLUSION: The gene polymorphism at IL - 1β - 511 was related to the production of IL - 1β, and the inhibitory effect of triptolide on the produc tion of IL - 1β was different in C/C, C/T, T/T genotype of IL - 1β -511, which may be one of the reasons for the phe nomenon that people respond differently to triptolide.
