microRNA (miRNA) is a class of endogenous small non-coding RNA (20-25 nt) which can regulate the expression of protein-coding genes post-transcriptionally and participate in a series of critical biological processes including cell proliferation,differentiation,metabolism,apoptosis,et al.Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma subtype.DLBCL is defined as the malignant lymphoma which originates from the B cells,with aggressive clinical behaviors and significant clinical heterogeneity.In recent years,the researches on miRNA in DLBCL have shown that several kinds of miRNA directly involved in the occurrence and development of tumors and there is a correlation between the miRNA expression profiles and molecular subtypes of DLBCL.As a kind of new molecular target,miRNA has a broad prospect in the application both for diagnosis and biotherapy of DLBCL.

Objective] The article summarizes the experience of using sanren decoction to treat pediatric diseases by Professor Liu Lin, the famous TCM physician of Hubei. [Methods] Through following Professor Liu Lin clinical diagnosis, organize his medical records, summarize the experience and thoughts of using Sanren decoction to treat pediatric diseases, and for some cases. [Results] Professor Liu Lin believes that the physiological and pathological characteristics of children prone to cause hot and humid accumulation, pediatric Chih-Yin is not substantial, with their lungs often delicate and spleens often inadequate, they prone to get hot and humid accumulation after sick, and later appear a variety of symptoms including upper burner, center burner and lower burner. Therefore, the treatment of pediatric disease should take the heat into account, bearing in mind the residence site of heat evil and syndrome differentiation. Professor Liu Lin makes good use of Sanren decoction to treat a variety of pediatric diseases, judging the residence site of heat evil and clinical manifestations, giving the corresponding treatment flexibly. Such as the treatment of bronchitis with almonds as the monarch herb to expectorant cough, treatment of infantile anorexia with White Kou Ren as the monarch herb to activate spleen and remove dampness, treatment of children with nephrotic syndrome with Yiyiren as the monarch herb for penetration of water, treatment of HFMD with the Sanren to regulate Qi of triple burner, according to the symptoms to medicate and always has good clinical effect. [Conclusion] Professor Liu Lin using Sanren decoction to treat pediatric diseases is effective, his thought is worthy of depth study and promotion.

Objective:To study the inhibitory effects of adenovirus mediated vascular endothelial cell growth inhibitor 151(VEGI_(151)) on venous endothelial cell proliferation. Methods: VEGI_(151) gene was cloned into adenovirus vector pCA13 and the product was packaged and amplified with 293A cells.The expressed protein was identified by Western blot. X-gal staining was used to determine the transfection efficiency of the recombinant adenovirus system. The inhibitory effect of Ad-VEGI_(151) on ECV304 cell proliferarion was observed and assessed by violet crystal assay. The protein expression of VEGI_(151) gene in ECV304 cells was detected by immunohistochemistry. Results: Liposome-mediated pCA13-VEGI_(151) and pJM17 cotransfection of 293A cells (through homologous recombination of intracellular plasmid) is a practical and feasible method to obtain high-titre recombinant adenovirus. The constructed Ad-VEGI_(151), with high transfection efficiency, significantly inhibited ECV304 cells proliferation and expressed functional protein in target cells. Conclusion: Ad-VEGI_(151) can express bioactive protein in target cells and can inhibit the proliferation of venous endothelial cells, and this may pave a new way for gene therapy of tumors and neovascular diseases.

Objective To investigate the anti-tumor effects of photodynamie therapy(PDT)on human pancreatic cancer xenograft in nude mice and the time-effect relationship of PDT.Methods The animal model of human pancreatic cancer was developed by suturing small pieces of SW1990 tumors into the dorsum of nude mice.When the size of the tumors increased to 0.8～1.0 cm.36 mice were randomly divided into three groups:control group(no treatment),photosensitizer group(Photosan 2mg/kg,abdominal cavity injection),photodynamic group(Photosan 2 mg/kg injection+laser irradiation).Each group included 12 mice.The tumor sizes were measured twice per week and the weight8 and volumes of the tumors were measured,and the tumor inhibitory rate was calculated three weeks later.Results The tumor volume of photodynamic group was (0.22±0.12)mm3 at the 6th day,which was significantly smaller than(0.43 s0.18)mm3 of control group and(0.39±0.15)mm3 of photosensitizer group(P＜0.05).15 days later,the tumor volumes of PDT groups increased.21 days later.the weight of the tumors in photodynamie group was(0.69±0.23)g,which was significantly lower than(1.65 ±0.21)g of control group and(1.62±0.12)g of photosensitizer group(P＜0.05).The tumor inhibitory rate in photodynamic group was 58.18%,which was significantly higher than that of photoseasitizer group(1.8%,P＜0.05).Conclusions Photodynamie therapy had significant anti-tumor effect on human pancreatic cancer with quick-acting efficacy,but photodynamie therapy alone exeaed efficacy only in the shoa term.

Objective To explore the alterations of intestinal mechanical barrier during the nonalcoholic fatty liver disease (NAFLD) progression. Methods To establish NAFLD rats' model,ninety male SD rats were divided into three groups equally: normal-diet group, high-sucrose diet group and high-fat diet group. At the 4th, 8th and 12th week each time point, ten rats were sacrificed in each group. Another twenty SD rats were randomly divided into carbon tetrachloride (CCl4) group and control group. The liver injured model of CCl4 group was induced by CCl4 ; all the rats of these two groups were killed at the 4th week. The degree of liver steatosis was observed through HE staining of liver paraffin sections. The lipopolysaccharide (LPS) level of portal vein blood was measured by limulus test. The occludin expression in intestinal mucosal was detected by immunofluorescent assay,and the fluorescence intensity was scored. The morphology change of intestinal mucosa tight junction was observed through electron microscopy. Results The liver histopathology suggested that NAFLD and liver injured rats' model was successfully established. There was no statistical significance of LPS level between high-sucrose diet group and normal diet group at all the time point (P＞0.05). At the 4th and 12th week, there was no statistical significance of LPS level between high-fat diet group and normal diet group (P＞0.05), while it was significantly higher in high-fat diet group than normal diet group at the 8th week (P＜0. 05). There was no statistical significance of LPS level between CCl4 group and control group (P＞0. 05). At the 8th week, the expression of occludin in normal-diet group, high-sucrose diet group and high-fat diet group was 1.80±0. 42, 1. 50 ± 0. 53 and 1.30±0.67, respectively, the expression was a little bit lower in high-sucrose diet group and high-fat diet group than in normal diet group, the difference was statistical significance (P＜0. 05). At the 12th week, the expression of occludin was significantly lower in high-sucrose diet group and high-fat diet group than normal diet group. The expression of occludin was significantly lower in CCl4 group (0.60±0.16) than in control group (1.80±0. 42) (P＜0. 05). No obvious morphology changes of tight junction was found in high-sucrose diet group, high-fat diet group and CCl4 group at each time point.Conclusion The expression of occludin decreased gradually during the non-alcoholic fatty liver disease progression. So in the NAFLD treatment, besides improving insulin resistance and protecting liver function,the protection of intestinal mucosa barrier as early as possible may slow down the progression of liver injury.
