Objective To study the efficacy and adverse reactions of the treatment on different types of infantile hemangiomas (IH) with different doses of propranolol .Methods One hundred and fifty cases of IH without contraindications were randomly treated with different doses of propranolol (low dose group:1 mg?kg -1 ?d-1 ;high dose group:2 mg?kg -1 ?d-1 ) under ECG monitoring inferior half an hour to breastfeeding taking ,and stay in hospital for observation for 6 to 24 hours after the treatment . The patients returned to the hospital for review every month(ECG and blood RT ;lung function in necessary) .Results The curative effect is better on strawberry IH than that on flat IH ,also better on deeply IH than that on superficial IH .The adverse reactions oc‐curred relatively slight in the low dose group and there was no significantly statistical differences on the treatment effects between the both groups(P>0 .05) .Conclusion It is safe and effective to treat IH with propranolol .

The full length cDNA of ?1,3 galactosyltransferase gene was amplified by RT PCR from the peritoneal macrophages of BALB/c mice, which was subcloned into an eukaryotic expression vector pCDNA3 1/V5 HisA, and it was confirmed by DNA sequencing. The gastric cancer cell GC9811 was transfected with pCDNA3 1/V5 HisA?1,3GT by Lipofectamine TM 2000. The positive clone was screened by G418 for two months and confirmed by RT PCR. The gastric cells expressing Gal?(1,3)Gal epitope were detected by immuohistochemisty, and they were killed by naive antidoby specific to Gal?(1,3)Gal epitope. The results showed that the pCDNA3.1/V5 HisA?1,3GT was successfully constructed, and the transfected gastric cancer cells could highly express Gal?(1,3)Gal, which promoted lysis of the cancer cells by normal human serum.

To analyze the composition regularity of Carthami Flos-containing prescriptions of the Drug Standards of Ministry of Health of People's Republic of China-Traditional Chinese Medicine Preparations (the ministerial standards for Traditional Chinese Medicine) based on the traditional Chinese medicine inheritance support system (TCMISS, RZDZ No. 0389952). Efforts were made to identify 331 prescriptions containing Carthami Flos and summarize 16 attending functions and 10 commonly used drug combinations. Three commonly used drug combinations were selected for an in-depth analysis on Carthami Flos's combined administration regularity. Based on Carthami Flos's attending functions, its effects in paralysis, traumatic injuries and dysmenorrheal were compared to analyze Carthami Flos's core drug combinations for treating different diseases. The regularity of clinical administration and the characteristics of commonly used drug combinations were summarized to provide reference for Carthami Flos's clinical application and new ideas for new drug R&D. Carthami Flos prescriptions was mainly used to treat blood stasis and pain and mostly combined with drugs that could activate blood, promote the circulation of qi and dispel pathogenic wind to treat Qi-stagnation and blood stasis caused by various pathogenic factors such as wind, cold and dampness.

Objectives To optimize the curriculum for better education quality. Methods By literature review, the curriculum of the bio-medical English program of Peking University was summa-rized. Interviews were conducted on 8 sophomores of the program based on convenience sampling for their concerns over the curriculum and a questionnalre was designed based on such concerns. Ques-tionnalre survey was used for the remarks and suggestions of the 129 graduates of year 2002, 2003 and 2004 on the curriculum, with 79 valid questionnalres collected and the data analyzed by Microsoft Excel. Results Respectively 64 (81.02%), 52 (65.82%), 53 (67.09%) respondents believe the se-quence, duration and connection of the English courses are appropriate and 65 (82.27%), 46 (58.22%), 50 (63.29%) respondents believe the sequence, duration and connection of the medical courses are appropriate. 63 (81.77%) respondents hoped that they could do experiments in the medical courses, but 18 of them (23.08%) worried that the experiments would make the curriculum more tense. 71 (89.97%) respondents thought that the internship at hospital in the curriculum was conducive to better understanding of medical course contents . Suggestions on the improvement of the curriculum were also made by respondents. Conclusions The curriculum could be further optimized, especially on the connection between different courses, although most of the respondents by and large believe that the curriculum of the program is rational and hold positive attitude towards the internship in hospital and experiments in the curriculum.

Objective Published literatures on the relationship between IL-13 gene polymorphism and the susceptibility of children to bronchial asthma in China were comprehensively analyzed with the use of Meta-analysis to evaluate this relationship.Methods The data were collected from the Medline database,Ovid database,the Cochrane library,and Chinese Biomedical database,and the references of eligible studies were manually screened.Published data related to case-control studies reporting the link between IL-13 polymorphisms and asthma in Chinese children were retrieved through those database.Meta-analysis was conducted to determine whether the IL-13 gene polymorphisms were associated with asthma.Results Eighteen studies were finally accepted for analysis.There were three studies focusing on C-1 112T polymorphism,and six studies focusing on C + 1923T polymorphism,and fourteen studies focusing on G + 2044A polymorphism.There was no evidence to confirm that the genotypes in position IL-13-1112 C/T were associated with asthma in Chinese children [odds ratio(OR) =1.00,95％ CI 0.82-1.22,P =0.98].The OR of asthma for TT/CC genotypes was 1.15 (95 ％ CI 0.57-2.33,P =0.69) and for CT/CC was 1.01 (95 ％ CI 0.82-1.25,P =0.89).There was significant evidence to confirm that the genotypes in position + 1923 C/T were associated with asthma in Chinese children(OR =1.86,95％ CI 1.29-2.67,P =0.000 9).The OR of asthma for TT/CC genotypes was 2.12 (95 ％ CI 1.27-3.56,P =0.004) and for TC/CC was 1.67 (95％ CI 1.18-2.35,P =0.003).There was no correlation between IL-13 + 2044G/A polymorphism and the susceptibility (OR =1.33,95％ CI 0.94-1.88,P =0.11).The OR of asthma for AA/GG genotypes was 1.30 (95 ％ CI 0.76-2.20,P =0.34) and for AG/GG was 1.24(95％ CI 0.90-1.70,P =0.19).Conclusions IL-13 gene + 1923 TT and TC genotypes should be associated with susceptibility of asthma in Chinese children,and the T allele could increase the risk of asthma.No clear relationship was found between the genotype TT/TC at the IL-13-1112 site and the incidence of asthma of children in China,and so was the genotype AA/AG at the IL-13 +2044 site and the incidence.

MicroRNAs (miRNAs) are a class of highly conserved single-stranded RNA molecules that modulate gene translation. By targeting the mRNA of protein- coding genes, miRNAs play a critical role in neuronal differentiation, cell proliferation, apoptosis and metabolism. There are a lot of miRNAs in central nervous system, which are not only closely linked to development, differentiation and function of nerve cells, also play an important role in nerve lesions and dysfunction after cerebral ischemia. Specific miRNA through their own changes affect their target gene expression levels after focal cerebral ischemia, involving in the protection against apoptosis in neurons and regeneration after cerebral ischemia. A full understanding of the specific microRNA function and its underlying mechanism in the brain can provide a new strategy for the prevention, diagnosis, and treatment of ischemic cerebral injury at gene level.
