Objective To observe the clinical therapeutic effects of BaDuanJin exercise on patients with scapulohumeral periarthritis.Methods 72 patients were randomly divided into therapeutic group and control group,with 36 cases in each group.The patients in control group were treated with electroacupuncture and those in therapeutic group were treated with electroacupuncture and BaDuanJin exercise for 4 weeks.Pain degree(VAS)and shoulder ROM(Melle Scores)were evaluated before therapy,2 weeks and 4 weeks after therapy.The patients were followed up for 3 months.Results The VAS scores and Melle scores of both groups after therapy(both at two weeks and four weeks)showed significant difference than those before thempy.The scores after 4 weeks therapy were better than those of 2 weeks therapy.The effects of therapeutic group after 3 months showed better result than controls,but without statistical difference(P>0.05).Conclusion BaDuanJin,as a mild exercise had favorable therapeutic effccts on patients with scapulohumeral periarthritis.

Objective To determine the serum level of KL-6 in patients with polymyositis(PM)and dermatomyositis(DM),and to investigate the possible diagnostic value for interstitial lung diseases(ILD)in pa- tients with PM/DM.Methods Serum KL-6 concentrations were measured by ELISA in 53 adult PM/DM pa- tients,the control groups of 22 patients with infectious lung disease,and 50 healthy subjects.The association with clinical features and serum KL-6 levels was analyzed.Results The serum levels of KL-6 were(1543?761)、(429?106)、(336?196)and(289?105)U/ml in PM/DM patients with ILD and without ILD,patients with infectious lung disease and healthy controls,respectively.Serum KL-6 levels in the PM/DM patients with ILD were significantly higher compared with PM/DM patients without ILD,patients with infectious lung disease and healthy controls(all P<0.01 ).However,no significant differences of serum KL-6 levels was found among PM/ DM patients without ILD,patients with infectious lung disease and healthy controls(P>0.05).Significant cor- relations were found between the elevated levels of serum KL-6 and the presence of ILD in patients with PM/ DM(P<0.01).The sensitivity and specificity of serum abnormal KL-6 levels for ILD in patients with PM/DM were 90.9% and 80.6%.Additionally,follow-up study showed the mean serum levels of KL-6 in six patients who died were significantly higher than that in other PM/DM patients with ILD(P<0.01).Conclusion Serum KL-6 level is a reliable serum marker for ILD in idiopathic inflammatory myopathies,which may contribute to early differentiate ILD from lung infectious disease.Increased serum level of KL-6 may predict a poor out- come.

Objective To explore the effects of citicoline injection into Zusanli point (ST36) on learning and memory function of rats after traumatic brain injury (TBI). Methods The model was induced with the improved Feeney method. The rats were randomly divided into 5 groups: sham-operation group, control group, acupuncture point saline injection group, intraperitoneal drug injection group and acupuncture point drug injection group with 8 rats in each group. The rats in the acupuncture point drug or saline injection group were treated with acupuncture injection of citicoline or saline daily. The rats in the intraperitoneal drug injection group and control group were treated with intraperitoneal injection of citicoline or saline daily. The treatment continued for 14 d. The learning and memory function was evaluated with the Morris water maze test and passive avoidance test. Results Acupuncture point injection of citicoline can significantly shorten the escape latent period of TBI rats in Morris water tests and extend the latent period of learning and memory of TBI rats (P<0.05). Conclusion Acupuncture point injection is effective on the recovery of learning and memory function of rats after TBI.

By UV induced mutagenesis of protoplasts of Saccharomyces cerevisiae strain f4, f5 and f6, and screening on plates containing different concertration of ethanol at different temperature, we obtained improved strains, such as f4.2, f5.1, f6.2, f4.5. By using a DES to deal with all the improved strains, We obtained two mutants, f5.1.1 and f4.2.1,which have improved ethanol torlerance. We made use of genome shuffling to generate improved strains in this work. We shuffled twice these improved strains by protoplast fusion and finally obtained strains with higher temperature and ethanol tolerance. we also identified shuffled strains that produced more ethanol by shake-flask experments. At the 35℃, the ethanol yield of R24 strain got to 12.93% (W/V), and were almost 5% higher than that of stain f4.

Objective:To explore the diagnostic value of color Doppler echocardiography for cardiac tumors .Meth-ods:Clinical data of 87 patients with cardiac tumors were retrospectively analyzed ,including their diseased loca-tion ,clinical manif′estations and echocardiography feature .Results:All cardiac tumors obtain pathologic confirma-tion .There were 73 patients (83.9% ) with benign cardiac tumors ,including 66 patients (90.4% ) with myxoma and seven patients with other types ;there were 14 patients (16.1% ) with malignant cardiac tumors .Echocardiography indicated that myxoma was often located in left atrium (n=58) ,most cases possessed pedicell,its activity was large ;Other type benign cardiac tumors feature :The 6 case (86% ) were generated inside cardiac muscle without pedicell, its echo was more strong ;malignant tumors:its attachment surface was wide without pedicell,and it may show with globular or cauliflower ,and accompanied hydropericardium mostly .Conclusion:Echocardiography can dynamically observe the form ,size ,echo and hemodynamic changes of tumors ,its diagnostic accuracy is high .Myxoma is most frequent cardiac tumor .

BACKGROUND:Current research has shown that many cellgrowth factors can promote the proliferation and differentiation of epiphysis stem cells, and this regulation is closely related to Sox-9.
OBJECTIVE:To investigate the effects of smal interfering RNA-induced specific silence of Sox-9 gene on the proliferation and apoptosis of epiphysis stem cells.
METHODS:Epiphysis stem cells were isolated from the ring of La Croix with enzyme digestion and purified with magnetic activated cellsorting, identified by immunocytochemistry assay. The cells in good conditions were selected to be transfected by Sox-9 silenced by smal interfering RNA with fluorescent marker, and then were observed under the fluorescent microscope to check the transfection efficiency. Next step, epiphysis stem cells were divided into 2 groups:group one was cultured normal y as control group;group two was transfected by Sox-9 silenced by smal interfering RNA through LipofectamineTM 2000 as experimental group.
RESULTS AND CONCLUSION:The primary epiphysis stem cells were separated and purified, which were of stable growth and tightly attachment. The results of immunohistochemistry and immunofluorescence showed the epiphysis stem cells expressed cel-specific markers, fibroblast growth factor receptor 3. After transfection, reverse transcription-PCR results showed that Sox-9 gene expression in epiphysis stem cellwas inhibited specifical y;3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide results showed that cellproliferation in experimental group decreased significantly compared with the control group (P<0.05), and the cellapoptosis detected by flow cytometry showed that the experimental group increased as compared with the control group (P<0.05). Sox-9 gene plays an important role in regulating the proliferation and apoptosis of rat epiphysis stem cells.
