1.Effects of Treadmill Training for One Week on α-actin Gene Expression of Rat Skeletal Muscle
Chinese Journal of Sports Medicine 2001;20(1):16-18
It was well known that the damage of skeletal muscle occurred and exercise performance declined after one prolonged eccentric exercise.But there were few studies on the adaptation to the continuous eccentric exercise in skeletal muscle.The purpose of this study was to investigate the effects of downhill running once(group B) and for one week(group C ) on α-actin gene expression of rat gastrocnemius muscle.Serum CK and LDH were determined, too.The results showed that the training had obvious effects on α-actin gene expression of rat gastrocnemius muscle in group B and C.In group B, serum CK and LDH recovered obviously 7 days after training, but not to the normal value.In group C, it recovered to the normal.These results suggest that the recovery of the damage after first training had been accelerated by the continuous eccentric exercise, the subjects gradually adapted to exercise.

Objective To evaluate the value of IL15mRNA determination in the early diagnosis and differential diagnosis of acute rejection(AR) after liver transplantation.Methods RT-PCR was used to detect the mRNA of IL-15 in serum and bile on the 30th day after liver transplantation in 43 patients subject to orthotopic piggy-back liver transplantation.Serum and bile of the patients were cultured for bacteria.The acute rejection was confirmed pathologically. Results Acute rejection(occurred) in 16 out of 43 cases as the AR group and bacterial infection(BI) in 12 cases as the BI group.The (remaining) 15 patients were uneventful as the control group.Before diagnosis of AR and BI,the gene expression rate of IL-5 in bile was significantly higher in AR group((62.5 %)) than in BI group((16.7 %)) and control group((13.3 %))(P
4.Progress on the study of the immunomodulating action of glucans from macrofungi
Chinese Pharmacological Bulletin 1987;0(02):-
Macrofungi are rich in natural bioactive compounds so they have much medicinal value.Their immunomodulating and anticancer activity particularly attracts more attention.Based on the polysaccharides molecular structure and their relation to these activities,this paper discusses their mechanism of the immune responses and introduces the important instances of these polysaccharides along with their immunomodulating and/or anticancer activity isolated from putative medicinal mushrooms.
5.Determination of Phthalates in Water by Solid Phase Extraction-Gas Chromatography-Mass Spectrometry
Journal of Environment and Health 2007;0(11):-
Objective To establish a method for the determination of phthalates in water by solid phase extraction-gas chromatography-mass spectrometry(SPE-GC-MS).Methods The water samples were extracted and enriched by solid phasse extraction,using 10%methanol-methyl tert-butyl ether as eluant,dimethylphthalate(DMP),diethylphthalate(DEP),dibutylphthalate (DBP)and diethylhexylphthalate(DEHP)were determined by gas chromatography-mass spectrometry with selected ion monitoring mode(SIM).Results The concentration had a good linear range in the range of 0.00~10.00?g/ml,the correlation coefficient was above 0.998.The detection limit of DMP,DEP,DBP and DEHP were 2.7,2.1,1.6 and 2.5 ng/L respectively,the average recovery rate and the RSD of the method were 78.0%~102.5%and 3.3%~7.8%respectively.Conclusion This method,with small amount of solvent,is simple,fast,accurate and is applicable to the determination of phthalates in water.
6.Recent progress in research of protective effects of erythropoietin on cerebral ischemia
Chinese Journal of Clinical Pharmacology and Therapeutics 2002;0(06):-
It has been proved that erythropoietin has neuroprotective effect and therapeutic action on cerebral ischemia in vivo and in vitro. The mechanisms of these actions may be involved in anti-exitotoxicity of aminoglutaric acid, regulating the synthesis of nitric oxide, antioxidation, antiinflammatory, inhibiting neuron apoptosis, accelerating angiogenesis, neurogenesis, neurotrophy and others. In addition, exogenous erythropoietin can enter brain tissue through blood-brain barrier and exert neuroprotection. So it is indicated that erythropoietin can be expected to be a new drug to prevent and treat cerebral ischemia.

8.Analyses of related factors and prediction of outcome in emergency intensive care patients with sepsis
The Journal of Practical Medicine 2017;33(11):1822-1825
Objective To perform APACHEⅡand SOFA in assessmentof EICU patients with sepsis ,and analyze the risk factors. Methods A retrospective analysis from January 2014 to October 2015 in EICU of our hos-pital ,a total of 83 patients suffered from sepsis ,including sepsis group(30 cases)and septic shock(53 cases). PCT,PT,APTT,lactic acid,mechanical ventilation time and APACHE Ⅱ and SOFA score were collected, through the receiver-operating characteristic curve(ROC)index to predict the prognosis of patients with sepsis.Re-sults The mortality of the patients in the septic shock group,PT,APTT,APACHEⅡ,SOFA score,mechanical ventilation time and PCT were significantly higher than thosein the sepsis group(P<0.001). APTT,APACHEⅡ, SOFA score and mechanical ventilation time had significant difference (P ≤ 0.001) between survival and dead. The lactic acid level of the dead group was significantly higher than that in the survival group(P=0.038). The ar-ea under curve(AUC=0.806)of APACHEⅡscore was better than the SOFA score(AUC=0.765).The outcome of sepsis had correlation with APACHEⅡ,SOFA score,lactic acid,and mechanical ventilation time(P<0.05). Conclusion APACHE II and SOFA scores can accurately predict mortalityoutcome in emergency intensive care units patients with sepsis,especially the APACHEⅡscore.We can measure blood coagulation function,APACHEⅡ,SOFA score,PCT,lactic acid and mechanical ventilation time to assess the severity of patients with sepsis.
9.Research progress on prostate biopsy and positive predicting factors
International Journal of Surgery 2017;44(3):207-211
New method of prostate cancer has grown more precise with the development of medical imaging.Multi-parametric MRI targeted biopsy and fusion biopsy reduce the cores,at the same time they have similar positive rates compared to systematic biopsy.The most used biopsy methods are still transrectal guided transrectal biopsy and transperineal biopsy in China.If we can predict biopsy result before the operation by physical and laboratory examination,it will help improve the detection rate and avoid repeating biopsies.And it has been indicated that age,tPSA,PSAD,fPSA/tPSA,PV,DRE,PHI and PCA3 are the predicting factors.Chinese Prostate Cancer Consortium Risk Calculator is fit for Chinses people.
