Objective To study the influence of interim overload exercise on health and it's biochemical mechanism.Methods 45 Wistar rats were randomly divided to three groups(n=15):no exercises group(control,C),normal exercise group(NE,the rats ran in the animal running machines at 15 m?min-1for 5 d in one week,exercise time was 30 min?2,and rested for 10 min after ran for 30 min),overload exercise group(OE,the rats exercised 2 bouts,2 d in consecutive in one week,exercise time was 100 min?2,and they rested for 10 min after ran for 100 min).After training for 8 weeks,the rats in three groups were sacrificed and 15 biochemical indexes in blood of rats were determined.Results Compared with C and NE groups,CK,LDH,and ALT increased obviously(P

Objective To explore the mechanism of long chain noncoding RNA RORin regulating prolifer-ation and apoptosis of pancreatic cancer cell. Methods Pancreatic cancer cell line BxPC-3 was selected. The RNA level of lncRNA ROR and notch1 was detected by RT-PCR.Notch1 protein level was detected by Western blot. The regulating relationship between lncRNA ROR and notch1 was analyzedby RNAhybird and luciferase re-porter assay. At last ,CCK-8 and TUNEL were applied to detectthe proliferation and apoptosis of cell line. Re-sults lncRNA ROR and notch1 were highly expressed in pancreatic cancer tissue ,compared with normal tis-sues. There was positive correlation between them. lncRNA ROR was over-expressed in BxPC-3,cell proliferation activity was increased and the percentagesof DNA damaged positive cells was decreased ,accompanied by in-creased levels of notch1 mRNA and protein. Luciferase assay confirmed that ROR could bind to notch1and inhibit its activity by miR-137. Compared with control group ,the proliferation of pcDNA-ROR + si-notch1 cells reduced and the proportion of TUNEL positive cells increased. The differences were statistically significant. Conclusionl ncRNA ROR regulated the proliferation and apoptosis of pancreatic cancer cells by promoting the expression of notch1.

Objective By compared FAB classification of myelodysplastic syndrome with WHO classification of myelodysplastic syndrome,understanded the proposed WHO new classification of myelodysplastic syndrome as soon as possible.Methods Retraced and analysed 78 cases of myelodysplastic syndrome based on examination of the bone marrow.Restults(1)According to the FAB classification,divided myelodysplastic syndrome into 5 kinds:RA,RARS,RAEB,CMML,RAEB-T.(2)According to the WHO classification,its subtypes were adjusted again,and its concluded:RA,RARS,RCMD,RAEB-Ⅰ,RAEB-Ⅱ,5q-del.(3)There were 9 cases possess chromosome to revise particularly in the chromosome check 28 cases myelodysplastic syndrome. Conclusion WHO classification has clinical guiding significance for early diagnosis,therapy observation and prognosis decision.

Objective: To investigate the protective effect and mechanism of JXHG Decoction on alcoholic liver injury.Methods: Each group of mice were fed for 30 days.Then 50% alcohol used to establish hepatic injury in mice by intragastric administration.16 hours later, the levels of TNF-α, AST, ALT in serum and MDA, GSH, TG, Caspase-3, Caspase-8 in liver were measured accordingly.Results: JXHG Decoction could reduce the levels of TNF-α, AST, ALT, MDA, TG, Caspase-3, Caspase-8, NF-κB and increase GSH, while alleviated tissue necrosis and aelipose degeration of hepar.Conclusion: JXHG Decoction has favorable anti-effects on alcoholic liver injury.Its possible mechanisms are reducing the inflammatory reaction by depressing the expression of TNF-alpha and NF-kappa B in liver cells, and alleviating the hepatic cell apoptosis induced by Caspase-8 and Caspase-3.

BACKGROUND:With the development of microsurgical techniques, free flap transplantation has been widely used, which can solve the problem of insufficient local tissues.
OBJECTIVE:To observe the clinical effects of latissimus dorsi free flap transfer on the repair of al kinds of body surface defects, as wel as the role in complete tissue and functional reconstruction.
METHODS:From 2010 to 2013, 18 cases of various types of body surface defects were selected and using the microsurgical techniques, these complex wounds were repaired with free latissimus dorsi myocutaneous flaps. According to defect reason, primary wounds were treated for arteriovenous separation in the recipient zone. Most of the flaps were latissimus dorsi myocutaneous flaps at the affected side which were cut according to the wound size. If the cut muscle flap had a larger size and secondary wounds were difficult to be directly sutured, free skin grafts could be used to cover the residual secondary wounds.
RESULTS AND CONCLUSION:After transplantation, al the flaps survived with normal blood supply and wel-recovered function. Patients were more satisfied with the flap appearance. Latissimus dorsi myocutaneous flaps characterized as large donor area and secluded location have a great advantage in the repair of complex wounds using microsurgical techniques that can improve the survival rate of latissimus dorsi myocutaneous flaps.

Objective To find the microorganisms which hydrolyze sugar residues of steroidal saponins at C-3 position and to obtain their glucosyl-derivatives.Methods The enzymes secreted by fermentation of Curvularia lunata((3.438 1)) in the culture medium were employed to transform polyphyllin Ⅴ(compound Ⅰ) and polyphyllin Ⅵ(compound Ⅱ).The products were separated by means of chromatography on C_(18) column and their structures were elucidated on the basis of spectral analyses.Results Compounds Ⅰ and Ⅱ could be transformed by C.lunata((3.438 1)) and the main products were identified as diosgenin-3-O-?-D-glucopyranoside,named trillin(compound Ⅲ) and pennogenin-3-O-?-D-glucopyranoside(compound Ⅳ),respectively.Conclusion The terminal rhamnosyls of polyphyllin Ⅴ and polyphyllin Ⅵ at C-3 position could be hydrolyzed selectively by C.lunata((3.438 1)) for the first time.

To explore the feasibility of stable expression of Hantavirus H8205 strain G1 segment and human IL-2 fusion gene in Vero cells, and to examine the immune protection effects on mice vaccinated with this recombinant eukaryotic expression vector containing Hantavirus G1 gene and IL-2 gene. With the help of lipofectamine, the Vero cells were transfected with pcDNA3.1/HisB-IL-2-G1 and the positive cells were selected by G418. IFAT and SDS-PAGE electrophoresis were used to determine the stable transfection and expression of recombinant protein. Each mouse was inoculated with plasmids intramuscularly (i.m.) three times, 2 boosts were given at 2-week intervals, serum anti-hantavirus antibodies were detected by ELISA and neutralizing antibodies (NAb) were detected by Plaque Reduction Neutralization Test. The fusion protein expressed in Vero cells was 78 kD, corresponding to the estimated molecular size. The neutralizing antibody titers of mice with pcDNA3.1/HisB-IL-2-G1 were 1:20-1:80. IL-2/G1 fusion gene could be transferred in Vero cells and stably express the fusion protein. Specific humeral immune responses in mice can be induced with the recombinant eukaryotic expression vector containing the fusion gene, which lays the foundation for further development of therapeutic HTNV vaccine.
