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.

Background Currently,the recommendation when treating acute biliary or pancreatic disease during pregnancy is to perform endoscopic retrograde cholangiopancreatography (ERCP) without radiation exposure,either empirically (with no radiographic guidance) or with ultrasound guidance.However,few published studies compared these two ways.This study aimed to compare ultrasound-guided ERCP with the procedure without radiographic guidance in the treatment of acute pancreaticobiliary disease in pregnant patients.Methods The clinical data of 68 pregnant patients with acute pancreaticobiliary disease admitted to our hospital between January 2004 and May 2010 were reviewed retrospectively.ERCP was performed without radiographic guidance in 36 cases (group A) and with ultrasound guidance in 32 cases (group B).Data on the following variables were compared between the two groups:surgical success rate,rate of complete stone removal,time to resolution of clinical manifestations and laboratory indicators,length of hospital stay,complications,outcome and differences in efficacy of ERCP during different stages of pregnancy.Results In group A,the rates of surgical success and complete removal of stones were 69% and 60%,respectively; the corresponding values were 91% and 89% in group B (P <0.05).Postoperatively,clinical manifestations improved rapidly in all patients; there was no statistically significant difference between the groups (P >0.05).Leukocyte counts and liver function had improved significantly after one week in all patients; they recovered more quickly in group B ((8.64±1.83)days vs.(14.57±3.74) days,(14.29±4.64) days vs.(20.00±5.40) days,P <0.01).The hospital stay was shorter in group B ((16.28±7.25) days vs.(28.00±6.83) days,P<0.001).The complication rate was 14% in group A and 3% in group B (P <0.05).There were no significant differences between the two groups in the procedure's efficacy during different stages of pregnancy.Conclusions In the treatment of acute pancreaticobiliary disease during pregnancy,ultrasound-guided ERCP is safer and more effective than performing the procedure empirically without radiographic guidance when performed by experienced practitioners.Its more widespread use is recommended.
9.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.

AIM:To investigate the role of minocycline on glutamate uptake in the periventricular zone and its putative mechanism after hypoxic exposure in neonatal rats.METHODS: A model of hypoxic-ischemic brain damage (HIBD) was developed by putting postnatal 1 d rat pups in 5%O2 for 3.5 h.The glutamate level in periventricular zone was measured by liquid chromatography coupled with tandem mass spectrometry assay ( LC-MS/MS) after hypoxic exposure for 4 h and 1 d.The dynamic changes of glutamate transporters EAAT1, and EAAT2 during developmental period in periventricular zone were determined by Western blot.Moreover, the expression of EAAT1, EAAT2, Iba-1, IL-1β, TNF-αand TGF-β1 was also detected by Western blot after hypoxic exposure for 4 h and 1 d in that region.The effects of mino-cycline on all parameters mentioned above were tested after minocycline treatment at the same time points and in the same region.RESULTS:After hypoxic exposure, glutamate level was increased, but it was decreased after minocycline treat-ment.EAAT1 and EAAT2 kept a low expression level at the first postnatal week, but a predominant elevation was found at the end of the second postnatal week.The expression of EAAT1, EAAT2, Iba-1, IL-1βand TGF-β1 was increased at 1 d after hypoxic exposure.EAAT1 and TNF-αexpression was significantly up-regulated, while EAAT2 was down-regulated af-ter minocycline treatment.CONCLUSION: Minocycline inhibits the increase in the glutamate level after hypoxia in periventricular region of the neonatal rats.The mechanism may relate to the selective regulation of glutamate transporters, rather than the inhibition of neuroinflammation in periventricular zone.
