[Objective]To discuss the initiating and developing mechanism of OPLL,and the influence of different operations on happening and developing of OPLL.[Method]We subgroup healthy adult S-D rats into groups,did operation on C 3~6 level.The first group:laminectomy;the second group:laminectomy and muscle cutting;the third group:muscle cutting only;the fourth group:exposure only;contrasting group:no treatment.We got the tissue of posterior longitudinal,ligament at 1,2,4,and 8 weeks post-operation and quantify BMP-2 and BMP-7 by PCR method.[Result]BMP-2,BMP-7 increased significantly in the 1st,2nd and 3rd group compared with the contrastinggroup;BMP-2,BMP-7 of only exposure group had no significant difference compared with the contrasting group.[Conclusion]BMP-2 and BMP-7 play important roles in the early stage of OPLL,they could be the on-setting factors of OPLL.BMP-7 may play an important roles in the later ossification period.

ObjectiveTo evaluate the efficacy and safety of domestic taerolimus in the manage-ment of acute rejection in renal transplantation reeipienta.MethodsA multieeneter, open and com-parative study for domestic Taerolimua and Prograf was performed. Eighty reeipienta of first allogenie renal transplantation were randomized into 2 groups: ①Experimental group (accepting Fumeixin ad-ministration, n=58) included 23 males and 35 females with the mean age of(39.1±9.6)years. ②Control group(accepting Prograf administration, n=22) included 12 males and 10 females with the mean age of(41.34±8.5)years. There was no significant difference in the volume, warm and cold is-chemia time of donor renal, age and sex of donor. All of the 80 cases accepted tacrolimus (domestic or foreign made, at the dose of 0. 10～0. 15 mg·kg-1·d-1 , q 12 h) treatment that combined with MMF and prednisone posttransplantation. Tacrolimus CO was aimed to 8-12 ng/ml in the first 60 days and 5-10 ng/ml later. The dose of MMF was according to the rule of each transplantation center based on the following recommendation: 1.5-2.0 g/d for the weight above 70 kg, 1.5 g/d for the weight 50-69 kg, and 1.0 g/d for the weight below 49 kg, in two divided doses. Prednisone was ad- ministrated as per ruler of each center. ResultsObservation termination was 3 months. Morbility of actue rejection was 3.40% (2/58)and 13.6% (3/22) in experimental and control group(P>0.05). Ad-verse events including hypertension, hyperlipemia, hyperglycemia and slight abnormality of liver func-tion occurred in 36. 2%(21/58) and 36. 4% (8/22) cases of experimental and control group(P> 0. 05). The survival rate in the 2 groups was 100%. The dose of tacrolimus in experimental group was significantly lower than that in the control group at 8 and 12 weeks posttransplant, while drug valley concentration in serum was proximal in 2 groups during the whole observation period.Conclusion Domestic tacrolimus capsules can be used effectively and safely in the management of acute rejection in renal transplantation.

Objective To discuss feasibility and therapeutic effect of the interventional management through biliary tract drainage with percutaneous transhepatic puncture technique for biliary tract stricture after orthotopic liver transplantation. Methods A retrospective review of the clinical and imaging materials of 292 postoperative orthotopic liver transplantation cases was made. Of these 292 cases, 30 patients suffered from biliary tract complications and treated with billiary balloon dilatation, bile drainage and biliary stenting techniques. Results After biliary balloon dilatation, 3 cases of biliary tract strictures and leaks, 3 cases of simple biliary anastomosis site strictures and 7 out of the 8 cases of multiple biliary tract strictures were cured. In one of the multiple biliary tract stricture patients, a hepatic hematoma after biliary balloon dilatation was found and a second liver transplantation was done. In the 14 cases of multiple biliary tract strictures accompanied with biliary sludge, balloon dilatation technique was repeatedly performed. In 12 of the 14 cases, the strictures were improved remarkably and jaundice was subsided; In one of 14 cases, biliary tract stenting procedure was performed, but liver re-transplatation was carried out because of stent obstruction by much sludge. In the remaining 1 of the 14 cases, because there was no improvement of the strictures and relief of jaundice was revealed after the repeated procedures, liver re-transplantation was finally done In 2 cases of strictures at the opening segment of the T tube, the procedure of percutaneous transhepatic puncture for bile drainage was managed. After the procedure, the strictures were alleviated and the jaundice relieved. Conclusion The interventional managements through percutaneous transhepatic puncture techniques were effective, convenient and minimally invasive for treating biliary tract strictures after orthotopic liver transplantation.

Objective To assess the impact of a single hemodialysis on the left ventricular systolic function of uremia patients with 3-dimensional ultrasound speckle tracking imaging (3D-STI).Methods Thirty-seven clinically stable outpatients with uremia undergoing hemodialysis were studied.The echocardiographic examinations were obtained in 30 minutes before and after homodialysis.Twenty nine normal subjects with age and sex matched were selected as control groups.Conventional ultrasound was recorded and then left ventricular mass index(LVMI) was calculated.The peak systolic mitral annular velocity S' was recorded by tissue Doppler imaging.3D-STI imaging were recorded from standard left ventricular apical 4-chamber views before and after a single hemodialysis.Left ventricular end diastolic volume (LVEDV),left ventricular end systolic volume (LVESV),left ventricular ejection fraction (LVEF),and left ventricular global longitudinal peak systolic strain (LVGLS),left ventricular global radial peak systolic strain (LVGRS),left ventricular global circumferential peak systolic strain (LVGCS),left ventricular global area peak systolic strain (LVGAS) were measured.The indicators of conventional ultrasound and 3D-STI were compared between the pre-hemodialysis group and the normal control group,and also between pre-and post-hemodialysis groups.Results ①Compared with the control group,the left ventricular end-diastolic diameter (LVDD),interventrieular septal thickness at diastole (IVSD),left ventricular posterior wall thickness at diastole(LVWPD),left atrial diameter(LAD) in the group before a single hemodialysis were significantly higher (P ＜0.05 for all).Meanwhile,the S' was significantly lower (P ＞0.05) and LVMI was significantly higher in the pre-hemodialysis group than the control group(P ＜ 0.05).The LVDD,LAD,left atrial volume index(LAVI) were significantly lower in the post-hemodialysis group than that in the pre-hemodialysis group(P ＜0.05 for all).②Results of 3D-STI showed that the LVEF,LVGLS,LVGCS,LVGRS,LVGAS was significantly lower,however LVEDV,LVESV were higher in the pre-hemodialysis group compared with the control group (P ＜ 0.05 for all).After a single hemodialysis,LVEDV,LVESV,LVGLS were significantly lower than before(P ＜0.05 for all),but LVEF,LVGRS,LVGCS,LVGAS were not significantly changed (P ＞ 0.05 for all).Conclusions After a single hemodialysis,the whole systolic function of the left ventricular was not changed.but the left ventricular global longitudinal peak systolic strain was significantly lower.The parameter of LVGLS was sensitive to the change of preload and was volume-load dependent.The preload of the patients should be sufficiently considered when the LVGLS are measured in the patients with uremia undergoing hemodialysis.

Objective To demonstrate the efficacy and safety of Hangzhou tacrolimus capsule(Saishi Tac capsule, Hangzhou Zhongmei Huadong Pharmaceutical Co. Ltd, China) in Chinese kidney transplant recipients. Methods Multicenter, randomized open-labeled, prospective controlled clinical trial was performed in de novo Chinese kidney transplant recipients. According to including and excluding criterions, 65 kidney recipients from 9 transplant centers were enrolled. The mean age of recipients was (36.53 ± 5.71 ) years, and 8 received living donor transplantion. The time of cold ischemia and warm ischemia was (4.08 ± 5.43) h and (3.90 ± 2.15) min respectively. The number of mismatched HLA was (2.1 ± 0.8). The recipients accepted Saishi Tac capsule + mycophenolate steroid 60 days, followed by 5-10 μg/L until the terminal observation time point (12 weeks after transplantation). The efficacy and safety were estimated during the period. The primary efficacy endpoint of the study was the incidence of biopsy-confirmed acute rejection. Graft survival and renal function (evaluated by serum creatinine) were the secondary endpoints. Safety was assessed by monitoring laboratory parameters and adverse events reported over the course of the study, such as infection, hepatic damage, hypertension, hyperlipema, diabetes mellitus and other adverse affairs.Results The dose of Tac at 1 st, 2nd, 4th and 8th week postoperation was (6.54 ± 1.69), (6.39 ±1.45),(6.73± 1.25), (6.25 ± 1.02) and (6.03 ± 1.16) mg, corresponding values to the C0 were (8.24±2.09),(9.39± 1.35),(9.93± 1.87),(7.23± 1.16) and (6.43± 1.26) μg/L. During 12weeks of follow-up, the incidence of biopsy-confirmed acute rejection was 12.3% (8/65), among which 6 cases were reversed by implosive therapy. The survival rate of graft kidney was 96.9% (63/65). The incidence of hypertension and hepatic damage was both 7.7% and morbidity of lung infection was 7.6%. There were 3 patients (4.6%) complicated with hyperlipema and diabetes mellitus respectively. Conclusion During the first 3 months of treatment Saishi Tac capsule was safe and effective to Chinese kidney transplant recipients.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.
