Objective To study the role of serum Hcy level change in predicting the effects of pemetrexed (PEM ) chemotherapy for treating the patients with advanced lung adenocarcinoma .Methods Fifty‐seven cases of lung adenocarcinoma treated by the PEM chemotherapy were retrospectively analyzed .The fasting venous blood was collected for detecting serum Hcy level before chemotherapy and at the end of 2‐week chemotherapy .The clinical characteristics ,Hcy level before and after chemotherapy and the relation between the Hcy level with clinical effect were statistically analyzed .Results In the therapeutic effects evaluated by the im‐aging examination during treatment process ,there were no case of complete remission (CR) ,19 cases of partial remission (PR) ,22 cases of stable diseases(SD) and 16 cases of progressed diseases(PD) ,the objective response rate(ORR) was 33 .3% and disease control rate (DCR) was 71 .9% .Different clinical factors had no significant influence on the efficacy of PEM chemotherapy (P>0 .05) .In comparing the influence of Hcy level and Hcy level change on the effect of PEM chemotherapy ,the results showed that serum Hcy level before treatment had no obvious influence on curative effect ,DCR in the patients with normal serum Hcy level after treatment was significant higher than that with abnormal Hcy level ,ORR and DCR in the patients with decreased Hcy level after chemotherapy were significantly higher than those with increased Hcy level (P<0 .05) .Conclusion Monitoring the serum Hcy lev‐el change during the PEM chemotherapeutic process in the patients with advanced lung adenocarcinoma may be used in the predic‐tion of the chemotherapeutic effect .

According to the practical problems including uneven distribution of medical resources in border areas , the difficulty of medical treatment for grass-roots unit, the low efficiency of referral between hospitals , and untimely mastery of health conditions of offi-ciers and soldiers , we constructed and developed a telemedicine information system based on hospital medical database with the backig of military integrated information network platform .A joint regional service platform among hospitals was constructed to realize high efficien -cy of medical referrals for officers and soldiers , computerization of personal medical information transmission , digitalization of health re-cords management , and paperless medical audit .The system provides convenient and high quality health care services , improves the level and efficiency of medical service , and enhances the ability of medical support to the troops by informationization .

Objective To investigate the protective effect of peroxisome proliferator receptor γcoactivator (PGC)-1αon he-patic ischemia-reperfusion injury .Methods The rat model of hepatic ischemia-reperfusion injury was established .The expression of PGC-1αwas detected by Western blot after 12 hours of reperfusion .The changes of reactive oxygen species(ROS) ,ATP level and serum liver enzyme activity were measured ,and the liver function was evaluated .On the other hand ,PGC-1α lentiviral overexpres-sion vector was constructed and transfected in rat before ischemia-reperfusion .After ischemia-reperfusion ,the expression of PGC-1α,liver ROS ,ATP level were measured by Western blot to explore the protective role of PGC-1αin liver ischemia reperfusion inju-ry .Results The expression of PGC-1α in ischemia-reperfusion liver was significantly lower than that in the control group (P<0 .05) .The level of ROS[(325 .4 ± 70 .9)RLU vs .(108 .5 ± 25 .2)RLU ,P<0 .05] ,the ALT activity in serum [(367 .8 ± 82 .7)U/L vs .(98 .7 ± 16 .8 )U/L ,P<0 .05]in ischemia-reperfusion liver were increased than that in the control group ,whereas liver ATP production was reduced[(6 .1 ± 3 .7)pmol vs .(19 .8 ± 3 .1)pmol ,P<0 .05)] .The expression of PGC-1αin the liver was significantly up-regulated by PGC-1αlentiviral overexpression vector (57 .3 ± 21 .3) U/L vs .(311 .2 ± 25 .8) U/L ,P<0 .05) ,down-regulated ROS[(98 .7 ± 18 .9)RLU vs .(300 .2 ± 45 .6)RLU ,P< 0 .05] and serum glutamic-pyruvic transaminase[(105 .3 ± 21 .3)U/L vs . (311 .2 ± 25 .8)U/L ,P<0 .05)] ,and increased liver ATP production [(17 .3 ± 3 .1)pmol vs .(5 .8 ± 2 .0)pmol ,P<0 .05]in contrast to non-transfected rats .Conclusion PGC-1αcontributes to protect liver ischemia reperfusion injury .
