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 evaluate the use of magnifying endoscopy combined with narrow band im-aging (NBI) system in diagnosis of early gastric cancer. Methods From March 2008 to December in 2008, a total of 56 patients with suspected gastric mucosal lesions were enrolled in the study. The lesions were ob-served with magnifying endoscopy combined with NBI and indigo-earmine-chromoendoscopy, and the results were compared with pathologic diagnosis from targeted biopsies. Results Out of 56 patients, 16 were diag-nosed as early gastric cancer pathologically. The accordance rate with the pathological diagnosis, sensibility, specificity, false positive rate and false negative rate of the magnifying endoscopy combined with NBI system were 94.6% (53/56), 93. 8% (15/16), 95.0% (38/40), 5.0% (2/40) and 6. 3% (1/16), respec-tively; while those of chromoendoscopy were 91.1% (51/56), 87. 5% (14/16), 92. 5% (37/40), 7. 5% (3/40) and 12. 5% (2/16), respectively (P >0.05). There was no difference between NBI and chro-moendoscopy in regarding of observing pit pattern, however, NBI was superior in displaying intrapapillary capillary loop. Conclusion Combination of magnifying endoscopy and NBI provides clear images of gas-tric mucosa and intrapapillary capillary, which is useful in diagnosis of early gastric cancer and can improve accuracy of biopsy. When combined with chromoendoscopy, it can further improve the yield of diagnosis.

Objective To understand self-harmonious state of medical college students at present,and explore the relationship between self-harmonious and social avoidance and distress(SAD).Methods 412 medical college students were assessed by self-consistency and congruence survey(SCCS),social avoidance and distal scores were 92.06±12.80).The self-harmonious of medical college students have differences in the grade.sex,one-child and area;and the difierences have not reached the remarkable level of statistics(P＞0.05),but the difference of self-rigidity between male students and female students(male:19.35±4.20;female:17.73±0.372,-0.152).Conclusion The self-harmonious level of medical college students Was low.And the bad SCCS state will lead to social avoidance or anxiety.

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.
