OBJECTIVETo investigate the impact of 1, 25-(OH)2D3 on left ventricular hypertrophy (LVH) in type 2 diabetic rats.
METHODSType 2 diabetic mellitus (DM) model rats were established by intraperitoneally injecting with 30 mg/kg streptozotocin. After 8 weeks, 19 male rats were identified as diabetic with left ventricular hypertrophy (LVH) by ultrasound examination, and randomly assigned into three groups: untreated (DM-LVH, n=7), treated with insulin (DM-LVH+INS, n=6), and treated with 1, 25-(OH)2D3 (DM-LVH+VD, n=6). Healthy male rats were used as the controls group (n=6). The fasting blood glucose and the insulin level were determined weekly. The left ventricular mass index, myocardial collagen content, collagen volume fraction, and 1, 25-(OH)2D3-receptor level were determined by 4 weeks later.
RESULTSIn the DM-LVH model group, the insulin level was significantly decreased compared with the non-diabetic control group (P<0.05), whereas the blood glucose, left ventricular mass index, myocardial collagen content, collagen volume fraction, and 1, 25-(OH)2D3-receptor expression were significantly increased (all P<0.05). In the DM-LVH+INS and DM-LVH+VD groups, the insulin levels were significantly increased compared with the DM-LVH model group (P<0.05), whereas the other parameters were significantly decreased (all P<0.05).
CONCLUSION1, 25-(OH)2D3 could reverse LVH in diabetic rats and that the mechanism may involve stimulating insulin secretion and reducing blood glucose via direct up-regulation of 1, 25-(OH)2D3-receptor expression.

It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".

BACKGROUND: Rat models induced by unilateral nephrectomy combined with adriamycin are widely used in screening anti-drugs of glomerular sclerosis. However, few reports concerning this method on inducing rabbit model of glomerular sclerosisOBJECTIVE: To establish a rabbit model of glomerular sclerosis, and to observe the renal function and histopathological changes during model preparation. DESIGN, TIME AND SETTING: Randomized controlled animal experiment was performed in Laboratory Animal Center of Kunming General Hospital of Chengdu Military Region between December 2008 and May 2009. MATERIALS: Twenty-five Japanese big-ear rabbits, weighing 1.75-2.25 kg, half males and half females, were selected to establish glomerular sclerosis models, and randomly divided into normal (n=10) and model (n=15) groups. METHODS: The left kidney of rabbits in the model group was removed under anesthetized with 30g/L saline solution of sodium pentobarbital (1 mL/kg). Rabbits in the normal group underwent a similar surgical procedure without kidney removing. At 1 week after operation, 5 mg/kg adriamycin was injected into rabbits in the model group, 3 mg/kg adriamycin was reinjected 2 weeks later. Same volume of physiological saline was injected in the normal group. MAIN OUTCOME MEASURES: The renal blood biochemical indexes were detected prior to and at weeks 4, 6, and 8 after model preparation. One nephridial tissue was harvested from each group to undergo pathological observation at week 8 after the second medication. RESULTS: ①Kidney in the normal group presented slightly white, slightly tough texture with smooth surface. ②Pathological features of focal segmental glomerulosclerosis was showed in the model group under a light microscope, presented as extracellular matrix hyperplasia, mesangial region expansion, renal glomerular capillary wall ball mix adhesion, tubule degeneration, or even interstitial fibrosis, as well as interstitial infiltration of inflammatory cells. ③Compared to the normal group, the total protein and albumin was and decreased, triglyceride, total cholesterol, low density lipoprotein cholesterol, urea nitrogen, and creatinine were significantly increased in the model group. The urine protein content of rabbits in the model group was obviously increased at 4 weeks, gradually reached a platform after 8 weeks, which still greater than that of the normal group. ④SPECT showed that the glomerular filtration rate of the model group was notably decreased (33 mL/min) than the normal group (92.6 mL/min).CONCLUSION: The unilateral nephrectomy combined with adriamycin in rabbits results in the formation of glomerular sclerosis, renal function and 24 h urinary protein is more visible in the phase change.

ObjectiveTo explore the feasibility of mediating recipient lymphocyte reaction with donor dendritic cells (DCs) in renal allograft recipients to guide individualized inmunosuppressive therapy. Methods From Jan. 2008 to Jan. 2010, 30 recipients received living related kidney transplantation were successively and divided into 2 groups according to the strategies of the correction of the dosage of immunosuppressant, 15 in each group. The strategy of immunosuppressive therapy in both groups was Tac + MMF + Pred. The correction of the dosage of immunosuppressant in experimental group was conducted by recipient lymphocyte reaction with donor DC (LR) combined with Tac and MPA blood concentration monitoring. Only blood concentration monitoring of drugs was applied in control group. Examinations of liver and renal function, blood and urine routine as well as blood sugar were done monthly for 1 year. ResultsDuring the follow-up period, the rate of acute rejection in experimental group and control group was 13. 3 % and 46. 7 % respectively (P<0. 05) ;the rate of infection in experimental group and control group was 6. 7% and 40. 0% (P<0. 05)respectively; the adverse reaction rate in experimental group and control group was 13. 3% and 46. 7%(P<0. 05). There was no significant difference in the serum creatinine level between the two groups at each observation point. ConclusionThe application of combined recipient LR with donor DC and blood concentration monitoring of drugs in individualized irnmunosuppressive therapy is more comprehensive and accurate.
