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.

Objective To evaluate the efficacy and safety of retroperitoneal laparoscopic pyelolithotomy ( RLP) combined with holmium laser lithotripsy under flexible cystoscopy in the treatment of complicated nephrolithiasis. Methods The retrospective analysis was made on the clinical data of 37 patients who underwent RLP and holmium laser lithotripsy under flexible cystoscopy for complicated nephrolithiasis from January 2013 to January 2014. The clinic parameters involved basic data of patients,operational time,blood loss,post-operative hospital stay,the status of stone-free,perioperative complications,and the follow-up data of patients were observed. Results No patient was converted to open surgery. The mean stone size was (2. 8 ± 0. 9) cm in diameter,operational time was (89 ± 24) min,blood loss was (21. 3 ± 7. 7) mL,post-operative hospital stay was (6. 8 ± 1. 7) d,the stone removal rate in one session was 94. 6%. One case occurred urinary leakage,1 case occurred fever after operation,who were all recovered through conservative treatment. All cases were followed up at the sixth months after operation. Conclusion RLP combined with holmium laser lithotripsy under flexible cystoscopy is effective and safe for the treatment of com-plicated nephrolithiasis.
7.Synthesis and anticancer activity of norcantharidin-galactose derivatives.
Acta Pharmaceutica Sinica 2008;43(2):157-161
To design and synthesize the hepatic targeting anticancer prodrug with norcantharidin (NCTD-Gal) conjugating structure, galactosylated NCTD derivatives were synthesized from NCTD analogues modified by a series of amino acids via acylation, hydrolysis, glycosylation and deacetylation. Seven new compounds were synthesized as beta-O-glycosides and characterized by IR, MS, NMR and element analysis. The compound 4a was chosen for the inchoate antitumor experiments on mice. The result showed that the antitumor inhibition rate of 4a groups with medium and high dose are clearly higher than that of NCTD group, which suggests that anticancer effect of NCTD is improved at a certain degree by galactosylation.

OBJECTIVETo investigate the characteristics of father-to-son vertical transmission of Y chromosome microdeletions
METHODSWe detected the Y by detection of Y chromosome microdeletions in infertile men and analysis of some of their families. chromosome azoospermia factor (AZF) microdeletions in the peripheral blood of 1 052 infertile males, investigated the paternal relatives of 12 cases of AZFc, 1 case of AZFb and 1 case of AZFb + c microdeletions, and drew the family tree diagrams of the infertile paternal relatives according to the findings.
RESULTSAmong the 1 052 infertile patients, 89 (9.73%) were found with Y chromosomal microdeletions, including 56 with AZFc, 6 with AZFa, 5 with AZFb, 14 with AZFb + c, and 8 with AZFa + b + c deletion. The investigation of the 14 patients'families revealed 1 case of AZFb and 1 case of AZFb + c deletion de novo. Among the 12 cases of AZFc deletion, vertical heredity was found in 5 patients with severe oligozoospermia, but not in the other 7 with azoospermia.
CONCLUSIONAZFe deletion may be vertically inherited from the father in severe oligozoospermia patients, and it is different from the paternal phenotype, while in azoospermia patients, AZF deletion, whatever type it may be, is less likely to be associated with vertical paternal heredity.

OBJECTIVETo investigate the effect of salidroside on hypoxia-induced apoptosis of corpus cavernosum smooth muscle cells (CCSMCs) in rats.
METHODSRat CCSMCs were cultured in vitro by the enzyme digestion method and identified by immunofluorescent staining of anti-alpha-SMA and anti-Desmin. The non-toxic dose of salidroside was determined by MTT assay. Low-oxygen mixed gas (1% O2, 5% CO2, and 94% N2) was piped into a modular incubator chamber to induce hypoxia. The CCSMCs were divided into a normal, a hypoxia, and a 32 microg/mL salidroside intervention group. The apoptosis of the CCSMCs was detected by flow cytometry and the expression of the caspase-3 protein determined by Western blot.
RESULTSThe majority of the CCSMCs were positive for alpha-SMA and Desmin at immunofluorescent staining. Salidroside at < 32 microg/ml produced no obvious toxicity to CCSMCs. Compared with the normal control group, the rates of early and late apoptosis of CCSMCs were both increased significantly in the hypoxia group ([12.77 +/-1.41]% vs [18.69 +/- 1.29]%, P < 0.01 and [14.63 +/- 2.00]% vs [21.03 +/- 1.530]% , P < 0.05). Western blot showed a markedly increased expression of cleaved caspase-3 (P < 0.01). Intervention with 32 microg/ml salidroside significantly reduced hypoxia-induced early apoptosis of CCSMCs ([13.46% +/- 1.87]%, P < 0.01) and decreased the expression of cleaved caspase-3 (P < 0.01).
CONCLUSIONSalidroside can reduce the expression of cleaved caspase-3 and inhibit hypoxia-induced apoptosis of CCSMCs in rats.

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.
