0.05). The DLCO, DLCO/VA, FEF25, FEF50, FEF75, which determines pulmonary gas exchange, revealed a statistically significant decline in patients with AP(P

AIM: To investigate the efficacy and safety of leflunomide (Lef) in long-term treatm ent of rheumatoid arthritis (RA).　METHODS: Twenty-one patients ［M 2,F 19; age (45±s 9)a］ with RA were s elected. Disease duration was (59±48) mo. All patients enrolled in double-blin d or single-blind trials with Lef 20 mg, po, qd for 6 mo at first. Doses of leflunomide in nine patients were reduced down to 10 mg, qd and all the others c ontinued the treatment with Lef at 20 mg, qd. 　RESULTS: All twenty-one patient s we re followed up for 1.5 a. The results showed that twenty patients had remarkable improvement and one patient had clinical remission. Ni neteen patients had been followed up for more than 2 a and twelve patients had r emarkable improvement while seven patients had clinical remission. Twelve pati ents had been followed up for 3 a and three of them had remarkable improvement while nine patients had clinical remission. Total rate of adverse reactions was 19 %( 4/21). 　CONCLUSION: This study shows that long-term treatment of RA with Lef is effec tive and safe.

Evidence based medicine (EBM) has drawn the attention of the medical community around the world and is rapidly becoming the standard in medical research. EBM requires both rigorous clinical trial research design, including adequate randomization and appropriate control, and accurate and thorough reporting of the findings of trials. Despite China's active research program, the majority of traditional Chinese medicine (TCM) clinical research in the Chinese literature fails to meet world standards of clinical research reporting, largely due to insufficient and inadequate reporting. Because of rising world demand for information on TCM research, enhancing the quality of research reporting in Chinese journals is imperative. Quality of reporting is important in all aspects of a manuscript, including the introduction/background, materials and methods, results, and discussion/conclusion sections. TCM journal editors, who serve as gatekeepers of quality, must encourage higher quality clinical research reporting by setting and upholding publication standards.

Objective To investigate the effect of resveratrol on proliferation inhibition,cell cycle arrest and apoptosis of Jurkat cell line in acute T lymphoblast leukemia.Methods MTT assay was used to determine the cell vitality.Wright-Giemsa,Hoechest 33258/PI staining and transmission electron microscope technique were used to detect the apoptosis status of Jurkat cells.The cell cycle arrest was analyzed by flow cytometry.(Results Resveratrol) had 64.01% inhibitory rate on the growth of Jurkat cells at 0.2 mmol?L~(-1) and inhibited the growth of Jurkat cells in dose-and time-dependent manner.24 h after treated with resveratrol,the typical features of apoptosis were observed under light and electron microscope in all treatment groups.Some nuclei showed bright blue under fluorescence microscope in the resveratrol-treated Jurkat cells,and the number of cells with bright blue fluorescence increased with time.Nuclei condensation and fragmentation were observed.Cell shrinkage,chromatin condensation,and marginalization were found by Wrigh-Giemsa staining and transmission electron microscope technique.By flow cytometry,62.57% of the cells were arrested at the S phase after exposured to(0.05 mmol?L~(-1)) resveratrol for 48 h,the rate of apoptotic cells to total cells was 12.01% in 0.05 mmol?L~(-1) treatment groups,and that in the control groups was 2.05%. Conclusion Resveratrol can inhibit the proliferation,cause S-phage arrest and induce the apoptosis of Jurkat cells.

This paper discusses the choice of textbook and reform of the teaching methods,as well as the issue of how to develop students’ practical and innovative ability the undergraduate teaching of pharmacoinformatics course.

Objective To analyze the reliability of MRI malignant signs of soft tissue masses in extremities.Methods MRI features of soft tissue masses were analyzed retrospectively with emphasis on 30 cases with malignant MRI signs based on pathologic results,and these 30 cases were divided into two groups(benign lesions and malignant tumor group).The reliability of malignant signs for malignant tumor was evaluated.Results(1)The qualitative diagnostic accurate rate for benign and malignant masses was 89.7% and the histopathologic qualitative diagnostic accurate rate was 66.2% by MRI;(2)The findings of invasion and edema around the masses in diagnosis of malignant tumors had a remarkable statistical significance among five malignant signs(P0.05);(3)The sign of indefinite sturcture of muscular fibrosis had statistical significance between benign and malignant tumor diagnosis(P

【Objective】 To establish the quantified standard of spleen-stomach damp-heat syndrome(SSDHS) in chronic superficial gastritis(CSG).【Methods】Based on the epidemiological survey,the factors related to SSDHS and non-SSDHS were quantified and scored,and then the quantified standard was set up and used for the degree grading of SSDHS.【Results】The diagnostic threshold value of SSDHS in chronic superficial gastritis was 49 points.The results of retrospective examination showed that the sensitivity,specificity,accuracy and likelihood ratio of qualified SSDHS standard are 90.91%,90.57%,90.72% and 9.64 respectively.The graded criteria of SSDHS were as follows:49～57 points for the mild syndrome,58～65 points for the moderate syndrome,and over 65 points for the severe syndrome.【Conclusion】It is indicated that the qualified SSDHS standard in chronic superficial gastritis is practical for its preciseness and rationality,and is worth of further study.

[Objective] To establish the animal model of spleen-stomach damp-heat syndrome (SDS). [Methods] Fifty SD male rats were randomized into 5 groups. Group A was fed with routine methods; group B was fed under the damp-heat environment; group C was fed with high fat and sugar diet and alternative feeding of fat and wine; group D was fed with a combined method of under damp-heat environment and giving high fat and sugar diet and wine; group E was fed by the method similar to group D and with Qingre Huashi Prescription at the same time. Fifteen days later, the symptoms and signs, and gastrin (GAS) and motilin (MTL) levels in the serum, plasma and gastrointestinal mucosa were observed to evaluate the models. [ Results] The symptoms and signs and pathological changes in Group D were similar to those of SDS. [Conclusion] The combined method of feeding under damp-heat environment and with high fat, sugar diet and wine supply a new data for the research of SDS.

The paper expounds the ethics problems caused by doctor's selling activities in consulting room,which means the conflicts between doctors and patients, purchase pressure implied in seeking medical ad vice, disgrace to the aim of medical service etc. Furthermore puts forward some suggestions about strengthening management, stopping doctors' selling activities:1. to curb doctors' selling activities in consulting room; 2. to formulate health law and regulations, standardize medical behavior; 3. to deepen health reformation, improve investment mechanism.
