Objective:To discuss the structure of medical humanistic curriculum system based on the research of quality features of excellent doctors .Methods:The goal , content and form of humanistic curriculum were based the factor of famous doctors'competencies which was build on the basis of literature review and experts'interview. Results:Ability and attitude or values accounted for high proportion of overall quality features .Humanities con-tained in most factors of excellent doctors'quality features;guiding significance of the structure of medical humanis-tic curriculum system is provided with excellent doctors'quality features .Conclusion:We should focus on the inte-gration of humanistic knowledge and practice , push humanities course into every stage of the medical education , further enrich category and quantity of medical humanities course and teaching form of medical humanities course , perfect the examination mode of medical humanities course in order to cultivate more excellent doctors .

ObjectiveTo explore the effect and safety of intravenous sodium valproate in treatment of pediatric patients with status epilepticus (SE).MethodsTwenty-five children suffering from convulsive SE were treated with intravenous sodium valproate after failure of the conventional treatment, in a dose of tolerability 15 mg/kg and 1～2 mg/kg daily.ResultsIn 25 cases, there were 23 cases (92%) with ≥50% seizure reduction and 11 cases (44%) with complete cessation. Except for winking in 7 cases (28%), no other adverse effects had been found.ConclusionIntravenous sodium valproate is effective and safe on pediatric patients with SE who are resistant to conventional drugs.

The DNA fragment was cloned from the cDNA that was synthesized using the RNA from Chinese white poplar and verified by sequencing This cDNA clone ,designated PtoCesA1, was 3215 bp long with an opening reading frame of 2934bp extending from nucleotides 52~2985.Comprision of the nucleotide sequence of PtoCesA1 with PtrCesA1 showed 97% identity.For construction of the PtoCesA1 binary expression vector, the BamHI site was made by synonymy mutation, the full length PtoCesA1 cDNA was subcloned into pBI121 between the BamHI site and XbaI site. The PtoCesA1 binary vector,containing PtoCesA1,was verified by digestion and PCR.

Objective The purpose of this study was to investigate the clinical significance of serum vascular endothelial growth factor(S-VEGF)in patients of esophageal squamous cell carcinoma with the end-point of progress-free survival rate.Methods Sera from 89 patients with esophageal squamous carcinoma,who presented and treated with concurrent chemoradiotherapy or surgical resection in Cancer Center d Sun Yat-Sen University from December 2002 to May 2004,were sampled at the time of pre-treatment.30 cases of health individuals without any evidence of disease were selected as control group.For patients with surgical resection were performed with esophagectomy and extended lymphadenectomy.For patients with concurrent chemoradiotherapy comprised of cisplatin and 5-fluorouracil.The radiotherapy dose of 2 Gy per day was initiated on Day 1 of chemotherapy and continued daily for 5 days per week for 6 weeks,for a total close of 60 Gy.Two courses of chemotherapy were given during radiotherapy at 6-week intervals.The serum vascular endothelial growth factor(S- VEGF)levels were measured with a solid phase enzyme Human VEGF Immunoassay ELISA kit.The end point of this study was progress-free survival,and time was calculated from the date of diagnosis to date of relapse or last follow evaluation.Results S-VEGF level of patients with esophageal squamous cell carcinoma was significantly higher than that of heahhy controls(475.93?44.76 pg/ml vs.294.20?23.40 pg/ml;P=0.020).S-VEGF levels in patients with StageⅢand StageⅣdisease were significantly higher than those in patients with Stage I and StageⅡdisease.The 1-year progress-free survival rate d high S-VEGF group(≥475 pg/ml)was significantly lower than that of the low S-VEGF group(＜475 pg/ml)(24% vs.66%;P=0.0004).The 1-year progress-free survival rate of the patients with StageⅠand StageⅡdisease was significantly higher than that of patients with StageⅢand StageⅣdisease(71% vs.29%;P=0.0015).The variables were assessed by multivariate analysis using the Cox proportional hazards model,and the results revealed that the clinical stage and the S-VEGF were first and second independent prognosis factor,respectively.Conclusions In the current study,a high S-VEGF was found to be associated with tumor progression,poor treatment response,and poor survival in patients with squamous cell carcinoma of the esophagus.

Objective To perform a molecular epideminlogical investigation on the types of Leptospira interrogans isolates from leptospirosis patients and animal hosts in Jiangxi province,using a pulsed-field gel electrophoresis (PFGE).Methods The extracted chromosomal DNA from leptospiral isolates were digested with restriction endonuclease Not Ⅰ and the DNA segments were separated by using PFGE.By BiOnurerics V4.0 software and 75% similarity as the standard,the obtained PFGE images from leptospiral isolates were managed to establish a digitization database and then the PFGE maps of leptospiral isolates were compared with those of reference standard strains belonging to 15 serovars in 15 serogroups of L.interrogans,for cluster analysis.Results 139 strains of L.interrogans isolated from different areas of Jiangxi province were classified into 46 PFGE types.Among the PFGE types,LepNot Ⅰ.0071,LepNotⅠ.0072 and LepNot Ⅰ .0043 were the predominant types that accounting for 28.06%,15.11% and 7.19% of all the leptospiral isolates,respectively.The PFGE maps from 84.89% (118/139) of the 139 leptospiral isolates were found to basically match those of 6 reference standard strains belonging to 6 serovar in 6 serogroups of L.interrogans.In the 118 matched ieptospiral isolates,32.37% (45 strains),15.83% (22 strains) and 15.11% (21 strains)belonged to sero-groups Icterohaemorrhagiae serovar Lai,sero-groups Australis serovar Australis and sero-group Javanica serovar Javanica,respectively.Conclusion PFGE seemed a fast,accurate and effective method for typing of L.interrogans isolates.Serogroup Icterohaemorrhagiae serovar Lai and followed by serogroup Australis serovar Australis as well as serogroup Javanica serovar Javanica were the predominant L.interrogans species in humans and animal hosts in Jiangxi province.

The DNA structures could be altered or even damaged by exogeous or endogenous factors during cell proliferation. Failure of effective and timely repair will lead to cell cycle arrest or apoptosis. By taking the advantage of the quick proliferation of cancer cells, DNA damage induction, cell cycle arrest and apoptosis promotion have become important strategies for ant-cancer chemotherapy. Previous reports showed that an array of natural compounds inhibit cancer cell proliferation by inducing DNA damage, which have therapeutic potentials for anti-cancer drug research and development.
