OBJECTIVE:To study the effect of Erdong granules on glucose metabolism and lipid metabolism in type 2 diabetes mellitus rats.METHODS:Type 2 diabetes mellitus model was induced by giving high-fat and high-calorie diet with intraperitoneal administration of streptozotcin for eight weeks.Model rats were divided into normal group,model group,streptozotcin group and erdong granules high-dose,middle-dose and low-dose groups.The levels of FBG,LDL-C,FFA,SOD and MDA were detected and immunohistochemistry method was used to determine the morphology change of islet cell.RESULTS:The serum levels of FBS,MDA,FFA and LDL-C in Erdong granules high-dose and low-dose group were significantly decreased while the activity of SOD was increased.Erdong granules could protect islet cell.CONCLUSION:Erdong granules can notably improve glucose metabolism and lipid metabolism,antioxidant enzyme activity and inhibit oxidative stress so as to protect islet cells of type 2 diabetic mellitus rats.

OBJECTIVETo investigate the effects of open reduction by palm side for the distal radius fracture and T shape plate internal fixation with simultaneous anterior transverse carpal ligament resection for the prevention of delayed carpal tunnel syndrome after operation.

METHODSFrom March 2000 to March 2007, 32 patients (8 males and 24 females, ranging in age from 46 to 66 years) with distal radius fracture were treated with open reduction by palm side and T shape plate internal fixation with simultaneous anterior transverse carpal ligament resection; while 30 patients (7 males and 23 females,ranging in age from 45 to 65 years) only with open reduction by palm side and T shape plate internal fixation. The incidences of delayed carpal tunnel syndrome between the two groups were compared.

RESULTSAmong 32 patients treated with open reduction by palm side and T shape plate internal fixation with anterior transverse carpal ligament resection, 3 patients had delayed carpal tunnel syndrome; while in 30 patients treated with open reduction by palm side and T shape plate internal fixation, 10 patients had delayed carpal tunnel syndrome. There was significant statistically difference (P < 0.05%).

CONCLUSIONSimultaneous anterior transverse carpal ligament resection can effectively prevent the delayed carpal tunnel syndrome occurrence for the distal radius fracture with open reduction by palm side.

Objective To investigate the effects of atorvastatin on parathyroid hormone1-34 (PTH1-34) induced neonatal rat cardiomyocytes hypertrophy and on the expression changes of small GTP-binding protein (K-Ras) and extracellular signal regulated protein kinases 1/2 (ERK1/2).Methods Neonatal rat cardiomyocytes hypertrophy was established with 10-7 mol/L rPTH1-34 in the presence or absence of 10-5 mol/L atorvastatin or 10-4 mol/L mevalonic acid (MVA).Cardiomyocyte diameter was measured by Motic Images Advanced 3.0 software,the synthetic rate of protein in cardiomyocytes was determined by 3 H-leucine incorporation and single-cell protein content was measured by BCA.The concentration of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) were determined by ELISA.Protein expression of ERK1/2、p-ERK1/2 and K-Ras was detected by Western blot.Results Compared to PTH1-34 group,cellular diameter was decreased 12.07 μm,3 H-leucine incorporation decreased 1622 cpm/well and singlecell protein content decreased 84.34 pg,ANP or BNP concentration reduced 7.13 μg/L or 20.04 μg/L,protein expression of K-Ras,ERK1/2 or p-ERK1/2 downregulated 0.81,0.19 and 1.44 fold,respectively,in PTH1-34 plus atrovastatin co-treated cardiomyocytes (all P ＜ 0.05).Compared to PTH1-34 plus atrovastatin co-treated group,cardiomyocyte diameter increased 4.95 μm,3H-leucine incorporation increased 750 cpm/well and single-cell protein content increased 49.08 pg,ANP or BNP increased 3.12μg/L or 9.35 μg/L aud protein expression of K-Ras,ERK1/2 or p-ERK1/2 upregulated 0.52,0.06 and 1.19 fold (all P ＜ 0.05) in MVA,PTH1-34 and atrovastatin co-treated cardiomyocytes.Conclusions Atrovastatin attenuates PTH1-34 induced neonatal rat cardiomyocytes hypertrophy through downregulating K-Ras and ERK1/2 pathway.

The aim of this study was to explore cytogenetic characteristics of acute promyelocytic leukemia (APL) and compare the interphase fluorescence in situ hybridization (I-FISH) with conventional cytogenetic (CC) analysis. A total number of 157 APL patients were recruited in this study, and the I-FISH and CC were applied to analyze cytogenetic features. Chromosome samples of bone marrow cells were prepared by short-term culture. Out of all 157 cases, 136 were observed with CC assay, 66 with I-FISH, of which 45 samples were analyzed with both methods. The results showed that among all 136 CC samples, t(15;17)(q22;q21) was found in 120 cases, of which 107 cases was isolated t(15;17)(q22;q21) abnormality, 13 cases was complex abnormalities and 12 case without mitotic figure. Among all 66 cases of I-FISH group, PMI/RARα fusion gene was found in 64 cases (97.0%), suggesting that I-FISH group was more sensitive than CC group (p = 0.041). It is concluded that combination of I-FISH and CC techniques plays a pivotal role for diagnosis and detection of minimal residual disease in APL.
