Hepatic ischemia-reperfusion injury(IRI)is a critical problem of liver surgery,especially when comes to liver transplantation.Presently.there are no effective measures for diagnosis,prevention and therapy of IRI,as the mechanisms of IRI still remain unclear.This review summarizes several new hepatic ischemia-reperfusion markers related to cell signal transduetion pathway.including transcription factor STAT,HIF-1 and PPARs,transmission factor MAPK,membrane receptor TLR4 and PARs.and iNOS.Animal studies have indicated that IRI was ameliorated by activating or blockading these markers,which might serve as targets for diagnosis,prevention and therapy of IRI.
2. Analysis of drug revenues in military hospitals by principal component regression
Academic Journal of Second Military Medical University 2012;33(4):417-420
Objective To establish a regression equation for drug revenues by analyzing the factors influencing drug revenues in seven military hospitals from 2007 to 2010. Methods The data were obtained from the financial and performance-effect data in 7 hospitals from 2007 to 2010; the database was created by Excel 2003 software. Principal component regression analysis was performed for variables including the hospital scale, amount of service, local economic level, drug add rate using SPSS 18.0 software. Results and Conclusion (1) Hospital scale and amount of service were the critical influencing factors of drug revenues in military hospitals; (2) Per capita cost of outpatient and inpatient also contributed to drug revenues; and (3) drug add rate and local economic level were negative influencing factors of drug revenues.

Pure culture of Phlebopus portentosus was inoculated in the roots of coffee tree. The results indi-cated that the young fruit bodies would come out around the rhizomes of host tree after inoculation in 30 to 90 days, single or cluster, 3 to 4 days for mature, weight 20.0 g to 62.0 g. Brown rhizomorph and hyphae can be seen on the seedlings`rhizome, main root and side root while nothing is on the tip of the root.It was found that rhizomorph on the surface of roots would die after inoculation in 90 days in pot.

OBJECTIVETo observe the efficacy of He-wei Jie-gu (Chinese characters) decoction on femoral intertrochanteric fractures after internal fixation in elderly.
METHODSFrom January 2010 to January 2012, 90 elderly patients with osteoporotic intertrochanteric fracture were randomly divided into two groups. The patients in experimental group were treated with open reduction and internal fixation, He-wei Jie-gu decoction and Caltrate D in oral, including 18 males and 27 females with an average age of (77.8±11.3) years old ranging from 65 to 89 years old;the time from injured to operation was 2 to 9 days with an average of (6.6±2.1) days; according to Evans-Jensen classification, 17 cases were in type I, 8 in type II, 15 in type III, 3 in type IV, 2 in type V. Meanwhile, the patients in control group were treated with open reduction and internal fixation, Caltrate D in oral, including 16 males and 29 females with an average age of (81.2±9.6) years old ranging from 67 to 91 years old; the time from injury to operation was 2 to 10 days with an average of (6.8±2.6) days; according to Evans-Jensen classification, 15 cases were in type I, 10 in type II, 14 in type III, 4 in type W, 2 in type V. The VAS score, hip BMD value before and after treatment, fracture healing and the Harris function score after operation were recorded and compared.
RESULTSAll patients were followed up from 3 to 9 months with an average of (5.6±2.8) months. Compared with the control group, the VAS score of the experimental group had an obviously reduction (F=98.138, P<0.01) after treatment; the hip BMD value at 3 months after treatment in the experimental group was higher than that of the control group (P<0.05); the fracture healing rate of the experimental group was higher than that of the control group (P<0.05); Harris score in 3 months of follow-up in the experimental group was higher than that of the control group (t=2.542, P<0.05); all the differences between two groups were statistically significant (P<0.05).
CONCLUSIONHe-wei Jie-gu decoction can reduce postoperative pain and increase bone mineral density after internal fixation of femoral intertrochanteric fracture in elderly, promote the fracture healing and functional recovery in the hip joint.

Objective To investigate the influence of atosiban on the pregnancy outcome in patients with repeated implantation failure(RIF)in blastcyst thawed embryo transfer(bTET) Methods From January 2014 to December 2015,a total of 262 RIF patients undergoing bTET were retrospectively studied. They were divided into study group with a single bolus dose (6.75 mg/0.9 mL,iv) of atosiban before bTET (n = 94),and control groupwithout atosiban(n = 168). Results The clinical pregnancy rate(57.41%),implantation rate(38.41%) and living-birth rate(46.81%) of study group were significantly higher than those of control group (41.12%, 28.32% and 33.93% respectively;P < 0.05). Although the abortion rate of study group was higher than that of control group(14.82% vs 13.04%),both the ectopic pregnancy rate(3.70%) and the multiple pregnancy rate (16.67%) were lower than those of control group(5.79% and 17.39%),and there was no statistical difference (P > 0.05). Conclusion Atosiban treatment before embryo transfer may improve pregnancy outcomes of RIF patients in bTET.

Background Pupillary light reflex has been widely used in the diagnosis and evaluation of visual system and nervous system diseases.However,in animal experiments,functional evaluation of the visual system and nervous system needs more advanced technology and are affected by many factors.Objective This study was to explore the use of the dynamic pupillometer in evaluating pupillary light reflex and to discuss the influence of brightness of stimulate on relevant curve parameters in C57BL/6 mouse.Methods Ten healthy SPF male C57BL/6 mice were collected in this experiment.White light of five luminance levels (2,8,32,128,256 cd/m2) was used to stimulate the mice following a 2-hour dark adaptation.The stimulation was given at the 60-second intervals,for a duration of 100 ms at every stimulation.An infrared camera and video capture card were used to capture digital images during the measuring process in a scotopic environment,at a speed of 60 frames per second.Measuring outcome was saved in the*.AVI format.A software that was developed by our group was used to determine pupil diameter and output pupillary light reflex curve offline.Pupil initial diameter (R1),constriction amplitude (CA),constriction velocity (CV),latency (T1),time for maximum velocity (T2),time for maximum constriction (T3),time for maximun con-striction to 10.1% R1 re-dilation (RT)and re-dilation velocity (RV)were assessed,and the correlations between luminosity and measuring parameters were analyzed using the Spearman rank correlation.The use of animals followed the Regulations for thd Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results R1 values showed no statistically significant difference among the 5 different luminosity groups(F=1.117,P=0.361).A positive linear correlation was found between stimulating luminosity and CA(r=0.508,P< 0.01),but negative correlations were seen between stimulating luminosity and CV or RV (r=-0.625,-0.609,P<0.01).T1 and T2 values in the 5 different luminosity groups were not statistically significant (F =0.202,P =0.936 ; F =1.584,P =0.195).The different levels of stimulating luminosity showed positive linear correlations with T3 and RT values (r =0.791,0.609,P< 0.01).Conclusions The dynamic pupillometer can quantitatively measure the pupillary light reflex of C57BL/6 mice.The pupillary light reflex dynamic curve parameters of mouse were affected by stimulus luminosity levels.These outcomes offer a basis for the application of the dynamic pupillometer system for measuring pupillary light reflex in animal models.
