A long course of systemic treatment with CsA in therapeutic dose to prolong skin allografts may produce severe toxic effects,therefore it is not acceptable for severe burn patients.Prior studies by one of us have reported that topical treatment with CsA will prolong the life of allografts.During the period of treatment,however,blood CsA levels were detected in high concentrations,similar to systemic use.The question occurs whether the immunosuppressive effect of topically applied CsA was due to local or systemic action.Two experiments were carried out.First,two skin grafts of ACI (RT1) ratswere transplanted on both sides of the back of same LEW (RT1) rat (n=56).The bandage was kept on for the first 5 postoperative days.One graft was treated topically daily with CsA 7.5mg/day in olive oil until rejection.At the same time,the other side was treated with olive oil alone as control.,The mean survival time (MST) was 12.38?0.70 and 9.14?0.33 d.,respectively,p

Objective To evaluate the soothing effects of hemodiafiltration on patients with refractoriness nephrotic edema and its influence on prognosis of nephrotic syndrome.Methods All the 15 cases involved had undergone hemodiafiltration periodically during acme edema and administered with the same standard loading dose of prednisone for 8 weeks.Meanwhile,clinical and lab indexes (urine volume,Cr,Bun,urinary protein,albumin) were measured.Results All patients improved in urine volume and renal function gradually after the treatment of hemodiafiltration for 1 to 3 times.By the 8th week of post-hemodiafiltration,urinary protein 24 h declines obviously[(6.42?2.31)g/d to (0.87?1.24)g/d].Conclusion Hemodiafiltration is an effective treatment in relieving retention of water,increasing the remission rate of protein urine,recovering patients' renal function and improving their prognosis to nephritic syndrome patients with severe refractory edema.

Objective To compare the efficacy,toxicity and prognosis on treating advanced non-small-cell lung cancer (NSCLC) between using weekly docetaxel (DOC) and using DOC associated with nedaplatin(NDP).Methods 56 cases of NSCLC patients were retrospectively analyzed.Group A included 34 cases who were treated with weekly DOC (35 mg/m2,dl,8).Group B included 22 cases who were treated with DOC associated with NDP (DOC 35 mg/m2,dl,8,NDP 80 mg/m2,d2).One treatment cycle was 21 days.Efficacy,toxicity and prognosis were evaluated after 2 treatment cycles.Results RR of group A was 8.8 ％ (3/34).RR of group B was 27.3 ％ (6/22).DCR of group A was 50.0 ％ (17/34).DCR of group B was 63.6 ％ (14/22).PFS of group A was 2.3 months.PFS of group B was 5.1 months.OS of group A was 8.7 months.OS of group B was 10.5 months.1-year survival rate of group A was 26.5 ％.1-year survival rate of group B was 31.8 ％.The above comparisons were not statistically different (all P ＞ 0.05).In adverse reactions,hematologic toxicity in group B was greater than that in group A (x2 =4.877,P =0.027).Other adverse reactions such as gastrointestinal reactions,fatigue and so on were grade Ⅰ-Ⅱ.Conclusions The treatment of weekly DOC used in advanced NSCLC is safe,effective an low toxicity.There are no significant difference of RR and PFS between single DOC and DOC associated with NDP.

Objective To investigate the therapeutic effect of endothelial progenitor cells(EPCs) in ameliorating rat progressive focal segmental glomerular sclerosis(FSGS) model induced by adriamycin.Methods Bone marrow mononuclear cells from male SD rats,after cultured by adherence method,were identified as EPCs.Female SD rats were divided into normal control group,adriamycin induced renal disease(ADR) group,EPCs transplantation group.ADR group and EPCs group underwent unilateral nephrectomy and received 5,3 mg/kg of adriamycin via tail vein 1 week and 2 weeks after operation,while the control group underwent sham operation and received 0.9% sodium chloride solution of equal volume.The whole body irradiation by 5 Gy X ray was done 1 week after the 2nd injection of adriamycin,then immediately 1?106 EPCs were transplanted via tail vein.The rats in control group and ADR group were only injected with 0.9% sodium chloride solution after whole body irradiation.The body weight and urine protein were measured before operation(0 week) and 4(1 week after EPCs transplantation),8,12 and 16 weeks after nephrectomy.Y chromatosome incorporation was detected with in situ hybridization at the 4th and 16th week.The histological and ultrastructural changes of kidney were evaluated at the 16th week.Results At the 4th and 16th weeks,Y chromatosome positive cells could be found incorporation in the area of glomerular and tubular epithelial cells.Since the 4th week,the weight of rats in both ADR group and EPC group became significantly less than that in control group and since the 8th week that in ADR group became less than that in EPC group(P

ObjectiveTo investigate the treatment and safety of interferon ? plus Ribovirin for chronic hepatitis C after kidney transplantation. MethodsFive patients with chronic hepatitis C after kidney transplantation were administered with interferon ? (50 ?g) subcutaneously once a week, plus Ribovirin (600 mg) orally once daily. The levels of HCV-RNA, ALT and serum creatinine in patients’ serum were monitored monthly. ResultsFour in 5 patients presented normal ALT and negative HCV-RNA in serum 12 weeks after treatment, and obtained sustained viral response 24 weeks after interferon ? plus Ribovirin therapy. During treatment, renal graft rejection did not occur. The most frequent side-effects were the decrease of leukocyte and hemoglobin, myalgia and fever, but did not influence the course of treatment. ConclusionCombination of interferon ? with Ribovirin can be a valid therapeutic option in renal transplant recipients with hepatitis C, and shows no influence on the renal function.

ObjectiveTo explore the clinical and pathological characteristics in diagnosing the renal diseases with diffuse glomerular nodular changes. MethodsThe clinical and pathological data of 127 patients whose renal pathological feature was mainly diffuse glomerular nodular changes were retrospectively analyzed. ResultsThe most common diagnosis was diabetic nephropathy and renal amyloidosis, and sometimes light chain deposit diseases and Mix cryoglobulinemia. ConclusionDiffuse glomerular nodular changes occurred in many diseases. We should make differential diagnosis based on the clinical symptoms, the results of laboratory examinations and the renal pathological characteristics.

Objective To observe the impact of transplant nephrectomy on panel reactive antibodies and a secondary renal transplantation.Methods Panel reactive antibodies in 15 patients with a failed renal transplant admitted in our hospital between 2004 to 2007 were measured before transplantation,before and 1 month,6 months,12 months after transplant nephrectomy,and the pathological changes were observed after transplant nephrectomy.Results Panel reactive antibodies was increasing after renal transplantation,and reached the highest level one month after transplant nephrectomy,then grandually got down.New HLA allosensitization sites were discovered after transplant nephrectomy.Large amount of C4d was stained in failed transplant.Conclusion Serum PRA increased after transplant nephrectomy.New HLA allosensitization sites were found,which may be useful in HLA matching.

Objective To identify the availability of video-assisted thoracoscopic thymectomy. Methods Retrospectively analyzed 68 patients with myasthenia gravis who underwent thymectomy including 34 cases of video-assisted thoracoscopic thymectomy and 34 cases of transsternal thymectomy,and the patients were followed up for 16 years. Results Patients of the VATS group were given video-assisted thora-coscopic thymectomy. The mean operative time was (90. 1 ± 15. 0) min,mean blood loss was (45. 0 ± 5. 5) mL,mean chest tube drainage time was (2. 5 ± 1. 2) days and mean postoperative hospital stay was (7. 0 ± 1. 2) days in VATS group,and there was no serious complica-tions and surgical death. The mean operative time was (98. 0 ± 12. 5) min,mean blood loss was (118. 5 ± 17. 5) mL,mean chest tube drain-age time was (4. 5 ± 1. 3) days and mean postoperative hospital stay was (11. 0 ± 2. 5) days in transsternal thymectomy group. 3 patients de-veloped MG crisis. There was no significant difference in mid-and long-term effects between the two groups(P>0. 05). ConclusionVideo-as-sisted thoracoscopic thymectomy for MG is safe and feasible with the advantage of less invasion,less surgical trauma,lower rate of complica-tion,and good curative effect compared with transsternal thymectomy.

s and no restenosis was found in 3 patients according to cerebral angiography. Preliminary results show that PTAS in the management of the vertebrobasilar arterial stenosis is a safe and effective method.

Objective To analyze the cognitive changes and influencing factors in patients with lacunar cerebral infarction after carotid artery intervention therapy. Methods Sixty lacunar cerebral infarction combined with carotid stenosis patients treated with artery intervention therapy (intervention therapy group) and 68 lacunar cerebral infarction without carotid stenosis patients treated with drug therapy (drug therapy group) were selected. The neuropsychological test was completed at entry and 1, 6, 12 months after entry, and the results were compared with 60 healthy controls (control group). The cognitive changes were observed. The neuropsychological test included mini mental state examination (MMSE), Montreal cognitive assessment scale (MoCA) and cognitive field test. Results There were statistical differences in other scores except the Stroop test C section and Wechsler adult intelligence scale (WAIS-RC) picture arrangement subtest at entry in intervention therapy group and drug therapy group compared with control group (P<0.05). There were no statistical differences in the all scores at entry between drug therapy group and intervention therapy group (P>0.05). In intervention therapy group, the MMSE scores, MoCA total score, Rey-Osterrieth complex figure test (ROCFT), auditory verb learning test (AVLT), and the WAIS-RC picture arrangement subtest, verbal fluency test, WAIS-RC digit span backwards subtest of performing function 12 months after entry were significantly better than those at entry, and there were statistical differences (P<0.05). MMSE score, MoCA total score, long-time delayed recall of ROCFT, the immediate recall, long-time delayed recall and short delayed recall of AVLT, semantic category fluency test of performing function and digit span backwards subtest of WAIS-RC 6 months after entry were significantly better than those at entry:(27.8 ± 2.2) scores vs. (26.4 ± 1.9) scores, (20.7 ± 2.3) scores vs. (19.3 ± 2.0) scores, (12.4 ± 3.2) scores vs. (10.8 ± 2.6) scores, (54.3 ± 10.6) scores vs. (49.9 ± 10.9) scores, (12.4 ± 2.0) scores vs. (11.2 ± 2.8) scores, (12.9 ± 2.0) scores vs. (10.6 ± 2.6) scores, (17.5 ± 4.0) scores vs. (15.4 ± 3.4) scores and (4.0 ± 0.9) scores vs. (3.5 ± 0.9) scores, and there were statistical differences (P<0.05). In drug therapy group, there were no statistical differences in the all scores 1 and 6 months after entry, compared with that at entry (P>0.05);the MMSE score, MoCA total score, ROCFT, the immediate recall, long-time delayed recall and short delayed recall of AVLT, WAIS-RC picture arrangement subtest, verbal fluency test, WAIS-RC digit span backwards subtest of performing function and digit span backwards subtest of WAIS-RC 12 months after entry were significantly better than those at entry, and there were statistical differences (P<0.05). There were no statistical differences in all scores 12 months after entry between intervention therapy group and drug therapy group (P>0.05). In patients intervention therapy group, Logistic regression analysis showed that the MoCA score was related with age, hypertension and low education level (P<0.01 or<0.05), but was not related with smoking, diabetes and interventional treatment (P>0.05). Conclusions Cognitive impairment in patients with lacunar cerebral infarction and carotid stenosis is severe and extensive, but most cognition disorders can improve to normal level 12 months after artery intervention therapy.
