0.05).CONCLUSION:Chitosan gynecologic suppository is safe,effective and more receptive for the patients,and the resistance is not easily produced for treatment of candidal vaginitis and bacteroidal vagina disease.Its advantage is that the patients can be treated without complete laboratory examination.

With the intensification of population floating in China, there has been a growing demand for ecdemic medical care. Because basic medical insurance in China conduct localized management, the differentiation between reimbursement policy and level in different areas result in the difficulty of immediate settlement. The great quantity of floating population are faced with rather heavy personal burden when need medical care at different locations, which to some extent restrict in-time healthcare for floating population. On the basis of analyzing the features of endemic medical care for floating population, it described three mode of typical immediate settlement on ecdemic medical care, discussed the main problems in restricting the flowing population get immediate settlement at different locations and put forward suggestions on improving the immediate settlement at different locations.

In order to improve the optimum temperature of lipases, The Penicillum expansum lipase (PEL) gene was mutated by site-directed mutagenesis using overlap extension PCR technique. The recombinant plasmid pPIC3.5K-lip-E83V containing matant gene was expressed in Pichia pastoris GS115. The comparison experiments of the mutant PEL-E83V-GS with the wild-type PEL-GS showed that: the optimum temperature of the mutant (45℃) was higher by 5℃ than that of the wild type. The thermostability of the mutant was similar to the wild type. The enzymatic activity of the mutant was 188 U/mL at 37 ℃, which was 80% that of the wild type at the same conditions. The hydrophobic interaction may be enhanced in the surface region by the hydrophilic amino acid, Glu substituted with the hydrophobic amino acid, Val, and be responsible for the improvement of optimum temperature.

· Mesenchymal stem cells ( MSCs ) are a population of multipotent stem cells with various neurotrophins from bone marrow which are widely used in tissue, cell repair and alternative research.Recently, some researches have shown that MSCs could enhance the viability of neurons under a pathological circumstance by secreting some neurotrophins. So the neuroprotection of MSCs can provide a new method of the treatment on retinopathy that it possible to promote cells survial and functional recovery.Here we make a brief review on the secretory function of neurotrophin and neuroprotective effects of MSCs on retinal cells and its application in the treatment of retinal disease.

Objective To evaluate the efficacy and safety of HyperCVAD/HDMTX-L regimen as salvage treatment for patients with diffuse large B-cell lymphoma. Methods A retrospective study was made to analyze the efficacy and adverse reaction of HyperCVAD/HDMTX-L regimen as salvage treatment for 54 patients with diffuse large B-cell lymphoma. 27 cases were divided in CHOP class scheme ineffective group, 24 cases in recurrence group, HyperCVAD/MA regimen were as the control group. The efficacy in the treatment of 4 cycles, side effects of all cycles and 3-year progression free survival rates of the two regimens were compared. Results In CHOP class scheme ineffective group, efficiency rate of HyperCVAD/HDMTX-L was 59.3%(16/27), 3y PFS rate was 73.3%, efficiency rate of HyperCVAD/MA was 61.9 % (13/21), 3y PFS rate was 61.5%. There was no significant difference in efficiency and PFS rate between the two groups (P>0.05). In recurrence group, efficiency rate of HyperCVAD/HDMTX-L was 47.8 % (11/23), 3y PFS rate was 54.5 %, efficiency rate of HyperCVAD/MA was 45.5 % (10/22), 3y PFS rate was 50.0 %, there was no significant difference in efficiency and PFS rate between the two groups (P> 0.05). The incidence rates of nausea and vomiting, aleukocytosis, thrombocytopenia, hemorrhage associated with chemotherapy in HyperCVAD/HDMTX-L group were significantly lower than those in the control group (all P < 0.001). Conclusion HyperCVAD/HDMTX-L regimen maybe replace HyperCVAD/MA as the salvage treatment of diffuse large B-cell lymphoma.

Chinese higher medical education has undergone a series of education reform project .College excellent courses construction is an important component of the project .To enable medical students to master the basic surgi-cal theory and skills, and to develop high -quality, high -level medical personnel , the surgery department in Shengjing Hospital of China Medical University has scored some achievements in constructing excellent courses . Some ideas and methods are summarized in the construction of excellent courses .

OBJECTIVE:To prepare Shuansaitong capsules and establish a method for its quality control.METHODS: Distillation method was applied to extract volatile oil from volatile oil-containing medical material and water decoction method was used to extract physic liquor from other medical material. Suitable quantity of excipients was added to prepare Shuansaitong capsules.Qualitative identifications of Ligusticum chuanxiong,Panax quinquefolium,Salvia miltiorrhiza,Angelica sisensis were performed by TLC,and the content of Gastrodin was determined by HPLC.RESULTS:The quality of Shuansaitong capsules was completely in conformity with the related requirements of China Pharmacopeia.The TLC spots were clear,well-separated,specific and free from interferonce of negative sample.The linear range of gastrodin was 0.1～0.5 ?g with a correlation coefficient of 0.999 5.The average recovery was 96.59% with RSD=0.47% (n=6).CONCLUSION:The preparation technology of Shuansaitong capsules is simple and the determination result was accurate,thus suitable for the preparation and quality control of Shuansaitong capsules.

In this paper the last study of the role of nitric oxide(NO) in the development of osteoarthritis is reported. The study of dependability of the content of NO in the inflamed tissue and development of osteoarthritis showed that NO had an important role in the damage of cartilage,and that the inhibition of excess release of NO could improve the repair of cartilage,and that the effective inhibitor of nitric oxide synthase might cure osteoarthritis.
