The strength and endurance of quadriceps and hamstring muscles have been considered important in sports injury prevention and causation. The purpose of this study was to determine the isokinetic strength and endurance of those muscles of 54 elite male athletes (mean age 21.6 years) and 35 healthy males served as a control group (mean age 20.1 years) using a Cybex Ⅱ~+ system. Three testing speeds (60?/sec, 180?/sec and 240?/sec) were selected.The results indicated that the strength values of the quadriceps and hamstring muscles were significantlly higher in athletes than that in the control group (P

Objective To investigate the present condition of unique copy of TCM ancient books, and analyze the literature value. Methods Bibliographic research was underwent first, then investigation table was made, investigation team for spot investigation was organized, the bibliography was sorted, and on this basis analysis of the literatures was performed. Results 59 collection units at home and abroad and 1370 unique copy TCM ancient books were investigated, which including 57 books published by photocopy and 37 books published by proof reading. Conclusion The unique copy TCM ancient books have important academic value and can be effectively saved and sorted through in-depth investigation and analysis.

Objective To obtain genes encoding the novel molecules for diagnosis of schistosomiasis. Methods The cDNA library of Schistosoma japonicum (Sj) schistosomula of day 15 post-infection was screened with positive patients sera,and the inserts of positive clones were sequenced. Then the sequences were compared with all sequences in GenBank database by Internet. The positive clones were analyzed by the software in bioinformatics. Results After three rounds of screening,15 positive clones were obtained,and among them 11 clones had the meaningful sequences,in which 5 genes coding for Sj mitochondrion,1 gene coding for Sj myosin and the others were SjCHGC05315,SjCHGC01371,SjCHGC04782,SjCHGC05166,SjCHGC09769,respectively. Conclusion Immunological screening by using positive patients sera can be used to discover Sj antigen genes with a potential value for diagnosis.

Tetraspanin 2-A(SjTsp2-A) gene was amplified by PCR.pcDNA3.1(+)/SjTsp2-A recombinant plasmids were constructed and transformed into E.coli DH5?.Twenty four BALB/c mice were randomly divided into pcDNA3.1(+) /SjTsp2-A group(A),pcDNA3.1(+)/SjGST group(B) and pcDNA3.1(+) group(C).Each mouse was injected through musculus quadriceps femoris by three times(two weeks interval) respectively with 100 ?g pcDNA3.1(+)/SjTsp2-A,pcDNA3.1(+)/SjGST,or pcDNA3.1(+).At two weeks after the final inoculation,mice were each challenged by 40?2 cercariae of S.japonicum.Forty-five days after infection,all mice were sacrificed,the number of worms collected and eggs in liver tisssue was counted.Anti-pcDNA3.1(+)/SjTsp2-A antibody was detected by ELISA and protein expression in quadriceps muscle by immunohistochemical staining.The worm reduction rate(44.4%) and egg reduction rate(28.4%) of group A was higher than those of group B and C(P

Objective To investigate the value of 18F-FDG PET/CT and serum CEA in patients with advanced gastric cancer after neoadjuvant chemotherapy combined with surgical treatment.Methods 96 cases of patients with advanced gastric cancer who underwent neoadjuvant chemotherapy combined with surgery as the research object,after more than 2 years of follow-up,PET/CT imaging and serum CEA levels were detected,and the diagnostic value of recurrence or metastasis of the two groups were evaluated and analyzed.Results Of the 96 patients enrolled in the study,there were 47 cases of recurrence and metastasis,PET/CT combined with CEA for recurrence or metastasis positive diagnosis rate and negative diagnosis rate was significantly higher than that of pure PET/CT and serum CEA,the difference was statistically significant(P<0.05).The sensitivity,specificity and accuracy of PET/CT combined with CEA in the diagnosis of recurrence or metastasis were higher than that of PET/CT and serum CEA,the difference was statistically significant(P<0.05).Conclusion The combined monitoring of 18F-FDG PET/CT imaging and serum CEA level in patients with advanced gastric cancer after neoadjuvant chemotherapy combined with surgical treatment is helpful to improve the diagnosis of metastasis or recurrence.

Employed staffs in military hospital are the basic power in the development of hospital, and they are playing an im-portant role in the military medical security.The article gives a detailed elaboration on the innovation and practice of employed staff man-agement in our hospital.In order to improve the efficiency and scientific management level of employed staffs, the innovative measure-ments in employment pattern, post management, education development, policy system, promotion passage are put forward in combination with current situation of employed staff in order to promote the construction of employed staffs and the development of the hospital.

At present,the medical profession generally acknowledged the best way to treat osteosarcoma is gene therapy,which includes tumor suppressor gene therapy,antisense gene therapy,suicide gene therapy,immune gene therapy,combined gene therapy,etc.But no matter what kind of gene therapy is that the gene must have a safe carrier.Gene therapy has made a breakthrough in osteosarcoma recently.On the basis of widespread use,we should emphasize the importance of gene vectors.

Objective To understand the status of the blood safety in Handan region to provide the basis for recruiting blood do-nors in our region and the data support for meeting clinical blood use.Methods The detection results of 5 legal indicators among unpaid blood donors in Handan region during 2002-2012 were investigated and analyzed.Results The total positive rate of indica-tors detection was 5.52%,in which alanine aminotransferase(ALT)was 4.06%,hepatitis B surface antigen(HBsAg),hepatitis C virus antibody(anti-HCV)was 0.54%,human immunodeficiency virus(HIV)antibody(anti-HIV)was 0.24% and treponema palli-dum antibody(anti-TP)was 0.12%.Conclusion This survey is conducive to the blood donor recruitment work and strengthening the screening of blood donors is helpful for safety of clinical blood use.

Aim To observe the effects of flavonoids,including galangin(G),kaempferol(K),apigenin(A),morin(M),quercetin(Q) and myricetin(MY),on myocardial apoptosis induced by H2O2,and explore the possible mechanism.Methods Primary cultured cardiocytes of neonatal rat were randomly divided into normal group,model group,and flavonoids group.Fluorescent staining,electrophoresis and Western-blot were employed to observe the cardiocyte apoptosis and proteins expression.Results Exposure to 100 ?mol?L-1 H2O2 for 16 h resulted in myocardial apoptosis significantly(P

This paper firstly introduced concept,advantages,disadvantages,and application prospect of free indexing. Then the theoretical feasibility of applying free indexing in the images of TCM ancient literatures was discussed with the combination of their characteristics.In the end,the article made examples to illustrate the application of free indexing in related subjects.
