Experimental crush syndrome was inflicted to the kidneys of rabbits and specimens of renal tissues were studied with electron microscope. It was found that apart from the damage to the renal tubules, the ultrastructural alterations of the glomeruli were also prominent and were characterized as follows:(1) Hypertrophy and hyperplasia of the glomerular cells resulting in narrowing and/or obliteration of the capillary loops.(2) Retrogressive changes of the glomerular cells in varying degrees such as mitochondrial swelling, dilatation of ER, vacuole formation, etc.On the basis of the morphological findings of the renal tissues in association with the clinical manifestations of acute renal failure (ARF), it is proposed that in addition to the damage of the renal tubules, a reduction of the glomerular filtration rate, which is the result of the altered hemodynamics in the renal vessels and the ultrastructural changes of the glomerular cells also play an important role in the pathogenesis of ARF.

The effects of androgen and glucocorticoid on the proliferation of SC-3 mouse breast carcinoma cells and their mechanisms were investigated in a serum-free culture. Both physiological concentrations of testosterone ( T) and pharmacological concentrations of dexamethasone ( Dex) significantly increased the cell proliferation. The growth-stimulatory effects of two hormones were mediated through their own receptors.SC-3 cells stimulated by T and Dex were also found to secrete fibroblast growth factor (FGF) like factor into conditioned medium (CM) . The addition of anti-FGF antibody in the medium inhibited T, Dex and bFGF-induced proliferation of SC-3 cells. Furthermore, the presence of FGF receptors in SC-3 cells were demonstrated. These results indicated that androgen and glucocorticoid-in-duced enhancement of SC-3 cell growth is mediated through an induction of FGF-like growth factor which acts on SC-3 cells as an autocrine growth factor.

Objective To observe the effects and safety of rapamycin (Rap) in combination with cyclosporine A (CsA) and steroid (Pred) as triple regimen for prevention of acute rejection after renal transplantation.Methods Fifty patients with de novo cadaveric kidney allograft were randomized into two groups. In the study group there were 30 patients treated with Rap, CsA, and Pred, while in the control group there were 20 patients with conventional triple therapy of azathioprine (Aza), CsA, and Pred. Same dosages of CsA and Pred were used in both groups. Any adverse event after treatment was observed and recorded in detail. The laboratory investigations were checked and analyzed periodically.Results The pre-protocol population included 26 patients in study group and 18 patients in control group. The 2-year patient and graft survival rates in both groups were 100 %. The incidence of acute rejection was 3.7 % (1/27) in study group, 25 % (5/20) in control group, respectively. All episodes of acute rejection were reversed by methylprednisolone. The trough levels of CsA kept same in both groups, but CsA dose in study group was lower than that in control group. Blood concentrations of total cholesterol and triglyceride in study group were higher than those in control group. Conclusion Rap is an effective and safe immunosuppressive drug for prevention of acute rejection after renal transplantation. Rap combined with CsA allows reducing the dose of CsA. But its main side effect is hyperlipidemia.

Objective To study the clinical features,the diagnosis and treatment of left renal entrapment syndrome. Methods Four male patients with left renal entrapment syndrome were reported.Their age ranged from 16 to 22 years.The clinical features were characterized by recurrent episodes of gross hematuria,and 1 case had left varicocele concomitantly.Cystoscopy showed hematuria from the left ureter orifice.B-ultrasonography and CT scan showed that the left vein was clearly compressed at the included angle of abdominal aorta and superior mesenteric artery and the proximal vein was dilated in all the 4 patients.The characteristics of onset and imaging, and treatment of left renal entrapment syndrome were reviewed and discussed with the relevant literature. Results The diagnosis was established in the 4 cases based on B-ultrasonography and CT scan.Left renal vein reconstruction was performed on them.The patients were cured and discharged,with renal vein outflow being normal and no hematuria occurring.At 6 and 9 months after operation,CT and ultrasonography showed that the kidney contour was normal,the reconstructed veins were patent,and the routine urine test results were normal. Conclusions Left renal entrapment syndrome clinically results in high pressure of renal vein,hematuria and left varicocele.Autotransplantation of the left renal vein is an effective treatment option.

Objective To measure and analyze the external nasal morphology of normal Uygur in Xinjiang,which will provide the anatomical basis for the rhinoplasty.Methods From the Department of Otolaryngology and Plastic Surgery of our hospital,we collected the Uighur patients' families as the research objects during January 2011 to December 2012,and at the same time Han nationality patients' families were set as control group.Related parameters of external nose measurements were completed,and the parameters of external nose of 95％ confidence interval calculated,and compared with those of Han people.Results The measured data showed that there were the 95％ confidence interval of the Uighurs external nasal related indicators; The nasal length,height,depth,dorsum slope length,temples,nasal tip angle of the male Uighur were greater than those of male Han; Uighur women had longer,higher nose,more slope length of the nose back,and greater nasal-facial angle and nosewing angle than that of Han women.The proportion of ultra narrow nasal type,narrow nose,the middle nose in Uighur men was 14.02％,79.50％,and 6.48％ ; that in Uighur women was 14.60％,67.72％,and 17.68％,respectively; compared with those in Han nationality,there was a significantly statistical difference (P＜0.05).Conclusions The external nasal morphology of the Uygur people in Xinjiang has its characteristics,with dominants of narrow nasal type; 95％ of medical reference range will provide an objective reference basis for the future clinical work.

Objective To summarize the clinical data of renal transplants survived with graft function more than 10 years and the adverse events during this period, and to discuss the main strategies for the long-term survival Methods Survival rate of renal transplants simultaneously survived with graft function > 10 years and grafts was counted respectively in total 1003 renal transplant recipients at our hospital before Dec. 31,1998 retrospectively. Their relevant survival,adverse events and initial post-operative immunosuppressive regimens were recorded simultaneously.Results As of Dec. 31, 2008, the 10-year survival rate of recipients was 62. 7% (629/1003), and recipients with graft function accounted for 85. 37 % (537/629). Of them, 94. 75 % (596/629) recipients received cyclosporine A (CsA) -based immunosuppression plus other antiproliferative immunosuppressive agents. Post-transplantation adverse events included coronary heart diseases in 57 cases (9. 06 %), liver damage in 32 cases (5. 09 %), malignancy in 29 cases (4. 61% ), diabetic mellitus in 25 cases (3. 97 %), apoplexy in 16 cases (2. 54 %), severe bone marrow depression in 14 cases (2. 23 %), femur head necrosis in 7 cases (1.11%), lower-extremity thrombosis in 3 cases (0. 48 %), sudden deafness in 2 cases (0. 32 %). There were 690 survival patients and 49 deaths including 19 (38. 78 %) due to cardiocerebral vascular accidents, 10 (20. 41%) due to malignancy, 9 (18. 37 %) due to hepatic failure, 4 (8. 16 %) due to infection, 3 (6. 12 %) due to treatment abandonment, 2 (4. 08 %) unknown reasons and 2 (4. 08 %) accidental deaths. Conclusion Long-term survival after renal transplantation is associated with the primary medication of CsA as the main immunosuppressive regimen. The non-immunologic factors such as the prevention and cure of cardioeerebral vascular diseases and the early finding of liver functional abnormality and tumor are the main points focused during follow-up.
