Objective To investigate the influence of long-term blood purification on atherosclerosis(AS) in maintenance hemodialysis(MHD) patients by measuring serum levels of homocysteine(Hcy) and carotid artery intima-medial thickness(IMT).Methods Seventy-two MHD patients visiting our hospital from June 2006 to December 2007,according to their blood purification mode,were assigned to three groups: hemodialysis(HD,n=25),hemodialysis+hemodiafiltration(HD+HDF,n=30),hemodialysis+continuous renal replacement therapy(HD+CRRT,n=17).Another 25 healthy subjects served as controls.Serum Hcy was detected before and after one-year treatment and meanwhile color Doppler ultrasonography was performed to check IMT of carotid artery and atheromatous plaques.Results The serum levels of Hcy,IL-6,MCP-1,hs-CRP in MHD patients were significantly higher than those in healthy controls(P

Objective To investigate the effect of radiation on the mitochondrion in adenocarcinoma A549 cells.Methods After A549 cells were irradiated with 0,0.5,3 or 8 Gy of 60Co γrays,mitochondrion membrane potential of A549 cells was detected by JC-1 probe,and ATP activity was measured by ATP kit in a chemiluminescence apparatus.The mitochondria DNA copy numbers was detected by real-time PCR assay.Results At 24 h after radiation,the mitochondrion membrane potential of A549 cells in all the irradiated groups changed significantly (F =243.44,P ＜ 0.05),among which 0.5 or 3 Gy of radiation resulted in a significant increase of mitochondrion membrane potential of A549 cells (t =-10.12,-5.59,P ＜ 0.05).However,the mitochondrion membrane potential of A549 cells exposed to 8 Gy of radiation decreased significantly 24 h after radiation (t =15.22,P ＜ 0.05).The mitochondrion membrane potential of A549 cells in all radiation groups returned to the normal level 48 h after radiation (F =10.36,P ＜ 0.05).24 h after radiation,the level of ATP in A549 cells significantly changed respectively(F =97.08,P ＜ 0.05),similar to the mitochondrion membrane potential.The ATP level in 0.5 and 3 Gy groups increased significantly (t =1.66,7.27,P ＜ 0.05),and the level of ATP in 8 Gy group decreased significantly (t =-8.24,P ＜ 0.05).Furthermore,48 h after both 0.5 and 3 Gy of radiation,the ATP content in A549 cells was still higher than that in untreated A549 cells (t =4.60,8.53,P ＜0.05).The mitochondria DNA copy numbers in A549 cells increased significantly in all the radiation groups (F =118.00,P ＜ 0.05).Compared with untreated A549 cells the mitochondria DNA copy numbers in A549 cells increased at 0.5 Gy by 12 times(t =0.02,P ＜0.05),and increased at 3 and 8 Gy by 7 and 10 times,respectively (t =9.68,15.10,P ＜ 0.05).Conclusions High dose of radiation resulted in the decrease of mitochondrion membrane potential of A549 cells,which subsequently affected the production of ATP.However,radiation with moderate and lower dose could lead to the compensatory increase of mitochondrion membrane potential of A549 cells,which promoted the production of ATP.The mitochondria DNA copy numbers compensatory would increase after A549 cells were exposed to radiation within 8 Gy.

Objective To compare the graft function of 2 methods of kidney harvesting,the modified method of combined liver and kidney procurement and rapid en bloc kidney procurement. Methods The clinical data of 220 cadaveric renal transplantation recipients were collected(12 months follow-up),174 cases from en bloc kidney procurement and 46 from combined liver and kidney procurement.The average harvesting time,the incidence of renal vein injury,1 year kidney survival and incidence of acute rejection were compared between the two methods.Results In average harvesting time and incidence of renal vein injury,the en bloc kidney procurement were better than the method of combined liver and kidney procurement.However,the method of combined liver and kidney procurement was better than the en bloc kidney procurement in 1 year kidney survival,1 year incidence of acute rejection and average warm ischemia time.There was no difference in 1 year survival of patients and 24 h,1 week and 1 year graft function after transplantation. Conclusion Although the method of combined liver and kidney procurement is better than the en bloc kidney procurement in 1 year kidney survival and 1 year incidence of acute rejection,there is no difference between the 2 methods in 1 year survival of patients and graft function after transplantation.

Objective To evaluate the clinical application of immediate breast reconstruction with the pedicle transverse rectus abdominus myocutaneons(TRAM)flap.Methods Ten breast cancer patients underwent immediate breast reconstruction with the pedicle TRAM flap after mastectomy,among which 4 cases used single pediele TRAM and 6 cases used bipedical TRAM.Polypropypene mesh were applied on all cases of patients to repair the abdominal defect. Results All the breast reconstructions were successful.Complications included grafting flap infection in one case and skin necrosis on partial abdominal skin flap in one case.The reconstructed breasts had a very good shape in 8 cases,and good in 2 cases.No local recurrence and distant metastasis occurred in the patients during the follow-up time ranging from 3 to 15 months. Conclutions Immediate breast reconstruction with the pedicle TRAM flap is an ideal breast reconstruction method for those patients undergoing mastectomy not only because it reconstructs the defective breast but for its cosmetic effect on the abdominal wall.

Objective To investigate the therapeutic effect of Danhong injection combined with metoprolol tartrate tablets on cardiac arrhythmia in climacteric women.Methods Retrospective a total of 115 patients with arrhythmia in The First People’s Hospital of Guiyang from May 2014 to May 2016 were divided into the western medicine treatment group and the traditional Chinese and western medicine treatment group.Western medicine treatment group were treated by metoprolol tartrate tablets, the traditional Chinese and western medicine treatment group were treated by Danhong injection combined with metoprolol tartrate tablets.The effect of two groups of patients after two months of treatment were observed,the heart rate variability,heart function index,sleep quality and the incidence of adverse reaction rate were compared between two groups of patients before and after treatment .Results After treatment,the effective rate of the traditional Chinese and western medicine treatment group was 98.33%, higher than the western medicine treatment group (P<0.05);the levels of SDNN,SDANN,RMSSD and PNN50 (%) were significantly higher in the the traditional Chinese and western medicine treatment group than those in the western medicine group (P<0.05);the levels of SV,LVPS and LVEF in the traditional Chinese and western medicine treatment group were higher than that in the western medicine treatment group ( P <0.05 );the sleep quality of the traditional Chinese and western medicine treatment group was significantly improved compared with the western medicine treatment group(P<0.05);the abdominal distension, nausea and vomiting,fatigue and cough incidence were no difference between the two groups.Conclusion Danhong injection combined with metoprolol tartrate tablets arrhythmia in menopausal women has a better therapeutic effect ,can obviously improve the patients with heart rate variability and cardiac function and adverse reactions occurred rate is low.

Objective To reproduce a rat model of collagen-induced arthritis with anemia,and to probe the effects of thalidomide on hemoglobin of these rats.Methods 128 male Wistar rats were randomly divided into 5 groups:Ⅰ(normal control group,n=24),Ⅱ(model group,n=26),Ⅲ(model group with high dosage of thalidomide,n=26,200mg?kg-1?d-1),Ⅳ(model group with low dosage of thalidomide,n=26,100 mg?kg-1?d-1)andⅤ(model group with methotrexate(MTX),n=26,2.7mg?kg-1?w-1).Every group was divided into 6 sub-groups(14,21,28,35,42 and 60d)according to different time points.The rat models with collagen-induced arthritis and anemia were reproduced by multiple subcutaneous injections at intervals of emulsion of collagen Ⅱ and Freund's complete adjuvant.Different kinds of treatment were given to the rats of different groups beginning on the 12th day after the first injection.The levels of hemoglobin in rats of group Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ were determined,and serological characteristics,morphologic changes,and serum iron content,total iron binding capacity,and pathological changes in bone marrow in rats of group Ⅰ and Ⅱ were observed.Results On the 28th day after the first injection,anemia appeared in rats of group Ⅱ,in which the hemoglobin level was lower significantly compared with that of group Ⅰ(P

Objective To investigate the efficacy and safety of anti CD25 Ab (Zenapax;Daclizumab) induction therapy in 62 patients following renal transplantation. Methods Sixty-two renal transplant recipients treated with Daclizumab induction therapy were analyzed retrospectively from Sep. 1999 to May 2004. Main immunosuppressive therapy regimen consisted of steroids cyclosporine and mycophenolate mofetil in all recipients after operation. According to Daclizumab dosage, these recipients were divided into 1-dose group, 2-dose group and over 2-dose group. All patients received Daclizumab 1 h before operation.Results The patients subject to Daclizumab were followed up from 3 months to 57 months. Seven of them had acute rejection ( 11.3 %) at intervals for 10.3 months, from 2 months to 14 months. Patient who had acute rejection at 10th month after operation lost his graft at 13th month after transplantation for graft dysfunction. The incidence of acute rejection was 15.6 % among 45 patients followed up over 12 months. Conclusions Induction therapy of Daclizumab could decrease the incidence of acure rejection, delay the time of acute rejection and relieve the severity of rejection. More graft can be long-survival. We can lower the dosage of CsA effectively and safely after induction of Daclizumab.

In order to compare the characteristics of ethano l production, a serie s respiratory deficient mutants (rho -) of Saccharomyces cerevisiae and the ir wil d parent strain (rho +) were assayed for ethanol yield, ethanol fermentation ki netics, ethanol tolerance, and activities of ethanol-dehydrogenase. The data i nd icated that: Though the average amount of ethanol produced by mutants rho - a nd by wild rho + strains were similar, some mutants produced a little more amount of ethanol than wild type. The kinetics curve of ethanol fermentation suggested t h at rho - mutants had a little higher ethanol fermenting speeds than wild type . Th e activity of ethanol-dehydrogenase per unit weight of protein of rho - mutan ts c ells were higher than that of wild strain rho +; the activity of ethanol-dehyd rogenase per unit volume of fermentation medium of rho + were higher than that rho - mutants,mainly due to the higher biomass of rho + were higher than that of rho - mutan ts. Some rho - mutants could tolerate higher ethanol concentration than wild rh o + stra in, but some not. If higher ethanol tolerance and higher ethanol yield rho - mu tants were used in fermenting process,higher ethanol yield would be expected,but some problems such as that rho - mutants grew slowly should be considered.
