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.

Objective To comprae the difference of Sex hormone,serum and follicular fluid anti Mullerian hormone (AMH) level tube,number of retrieved egg,the number of cleavage rate,fertilization oocytes,the number of available embryos and total embryo on in vitro fertilization and embryo transfer (IVF-ET) of different reaction groups,to explore the relationship between AMH and pregnancy outcome of IVF-EH.Methods Eighty-one cases of IVF-ET assisted pregnancy were divided into low ovarian response group,normal ovarian response group and high ovarian response group according to the response of the super ovulation.Serum sex hormone and AMH of all patients were detected on the third day of menstruation,on the day of HCG injection,oocyte pick-up (OPU) and embryo transfer (ET),AMH in FF were detected too.The difference of oocytes,cleavage rate,embryo quality and the indicators mentioned above among the three groups were compared.All of the above indicators were compared between pregnancy group and unpregnancy group.Results (1) The level of AMH on the third day of menstruation ((1.76 ± 0.47) μg/L,(3.45 ± 1.01) μg/L,(6.34 ± 1.29) μg/L,F =2.435,P＜0.001),HCG injection ((1.09±0.13)μg/L,(1.29±0.29)μg/L,(2.64±0.51)μg/L,F=1.542,P=0.001) and embryo planting((1.32±0.33) μg/L,(1.62±0.39) μg/L,(1o 91±0.41) μg/L,F =1.573,P ＜0.001) all were statistically significant in three groups.On day of OPU,the levels of serum AMH ((0.95±0.21)μg/L,(1.15±0.29) μg/L,(1.74±0.41) μg/L,F =12.573,P＜0.001) and AMH in FF((5.82±1.19) μg/L,(6.92±1.05) μg/L,(7.79±1.39) μg/L,F =9.83,P＜0.001) were statistically differences in the three groups.(2)The number of oocytes were positively correlated with AFC,based AMH,levels of E2,P and AMH on the day of HCG injection and OPU,E2 and AMH on the day of ET and AMH in FF(P＜0.05).(3)AMH in FF in pregnancy group was (6.22±0.82)μ g/L,significantly higher than those without pregnancy group ((5.31 ±0.71)μg/L,P =0.037).Conclusions Levels of AMH in serum and follicular fluid are good predictors of ovarian response in IVF-ET.The level of serum AMH can only predict ovarian response,but can not effectively predict pregnancy outcome.The level of AMH in FF is a good predictor of pregnancy outcome.

Objective To investigate the role of CD4+CD25+FoxP3+ in severe Mycoplasma pneumonia among children.Methods One hundred and forty children with M.pneumoniae pneumonia (65 severe and 75 non-severe) who were hospitalized were enrolled along with forty other children as controls.X-ray was assessed.The proportions of peripheral blood CD4+CD25+FoxP3+cells were determined by flow cytometry.Results Both severe and non-severe children had decreased CD4+CD25+FoxP3+cells as compared with control subjects in acute phase (0.87 ± 0.66％ vs.3.88 ± 2.00％,P ＜ 0.01 and 1.17 ± 0.70％ vs.3.88 ±2.00％,P ＜0.01,respectively).The levels of CD4+CD25+FoxP3+cells in severe children were lower than those in non-severe children in acute phase and recovery phase (0.87 ±0.66％ vs.1.17 ±0.70％,P ＜0.05 and 1.66 ±0.85％ vs.3.61 ± 1.45％,P＜0.01,respectively).Both severe children and non-severe children expressed higher CD4+CD25+FoxP3+cells in recovery phase than in acute phase (1.66 ± 0.85 ％ vs.0.87 ± 0.66％,P ＜0.01 and 3.61 ± 1.45％ vs.1.17 ±0.70％,P ＜0.01,respectively).Conclusion The expression of CD4+CD25+FoxP3+Tregs may play a role in the onset of severity of mycoplasma pneumonia and the low express of CD4+CD25+FoxP3+Tregs in children infected with M.pneumonia may increase the susceptibility to severe mycoplasma pneumonia.

The process of exercise regulating bone metabolism is complicated, which involves a number of signaling pathways. A large number of studies in vitro have indicated that mechanical stress regulates bone metabolism by Wnt, bone morphogenetic protein (BMP), and osteoprotegerin (OPG)/receptor activator of NF-κB ligand (RANKL)/receptor activator of NF-κB (RANK) signaling pathways. Both the in-tensity and frequency of mechanical stress have varing impact on bone tissue and cells. Plenty of studies in vivo also have shown that exer-cise regulates bone metabolism by key factors in bone metabolism signaling pathways. This paper reviewed the effects of exercise on bone metabolism pathways and their mechanisms.

Objective To study the association between three single nucleotide polymorphisms (SNP; rs2241766,rs1501299 and rs12495941) variants of the adiponectin gene (ADIPOQ) and polycystic ovary syndrome (PCOS) in PCOS family trios.Methods A total of 224 unrelated PCOS probands,their biological parents were recruited.Anthropometric variables such as waist circumference (WC),hip circumference (HC),height and weight were measured in all subjects during the first visit to the outpatient department.Body mass index (BMI) and waist-hip ratio (WHR) were calculated.Serum fasting glucose (FBG),fasting insulin (FINS),total cholesterol (TC),triglycerides (TG),low-density lipoprotein and highdensity lipoprotein cholesterol (HDL) levels were measured.PCOS patients were divided into two groups based on BMh group A (BMI＜25 kg/m2) and group B (BMI≥25 kg/m2).Parents of PCOS patients were accordingly categorized into group C,D (fathers) and group E,F (mothers).The transmission disequilibrium test (TDT) was used to analyze the association between three SNP of ADIPOQ and PCOS.Results (1) A significant positive association was detected between SNP rs1501299 and PCOS (x2=7.093,P=0.008).However we failed to find significant overtransmission of the other two SNP rs2241766 and rs12495941 from parents to PCOS offsprings (x2=1.620,P=0.203; x2=0.713,P=0.398).(2) Linkage disequilibrium (LD) was analyzed in the subjects,rs1501299 and rs2241766 were in weak LD (r2=0.063,D'=0.621).(3) The levels of WC,HC,WHR,testosterone,TG,HDL and FINS were significantly differences between obese and lean PCOS patients (P＜0.05).While in fathers we only found WC,HC,TC levels being statistically different (P＜ 0.05).Mothers of obese PCOS patients had increased levels of FINS compared with mothers of lean PCOS patients (P＜0.05).The genotype frequencies of the three SNP were not different in obese and lean PCOS patients and their parents (P＞0.05).Conclusions TDT confirms that SNP rs1501299 in the ADIPOQ is significantly associated with the risk of PCOS in the Chinese Han population.The three SNP of the ADIPOQ were not associated with the obesity of PCOS.

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.
