Objective To observe the effects of soy isoflavones (SI) on NO content and NOS activity in myocardial tissues of diabetic rats. Methods Forty-eight SD rats were randomly divided into six groups: normal control group (NC), diabetic control group (DC), SI groups in low, moderate and high doses respectively (L-SI, M-SI, H-SI) and nilestriol group (NI). Except the NC group, the rats were given streptozotocin (STZ) 55mg?kg-1 intraperitneally (ip). From the 7th week, SI in the dosage of 30, 60, 120 mg?kg-1?d-1 was respectively given to L-SI, M-SI, H-SI groups by gastric gavage, nilestriol 0.2 mg?kg-1?per week was given to NI group,and 0.5%CMC-Na10 ml?kg-1?d-1 was given to NC and DC groups. After treatment, fasting blood sugar level, body weight, serum lactate dehydrogenase (LDH)and creatine kinase (CK) contents, and NOS activities and NO content in myocardial homogenate were measured. Results 1) LDH and CK contents in serum were significantly higher in DC group than those in NC group. Compared with DC group, LDH and CK were significantly decreased in M-SI and H-SI groups (P

AlM: To evaluate the function of the microprobe dredging technology in the treatment of meibomian gland dysfunction ( MGD ) and to provide fast, efficient, economical and practical method of treatment for meibomian gland dysfunction ( MGD) .

OBJECTIVETo compare the clinical effect and complications of subfascial breast augmentation and submammary breast augmentation.

METHODFrom Sept. 2009 to May 2012 , 25 patients with subfascial breast augmentation and 31 patients with submammary breast augmentation were observed. The postoperative results including visible implant edge or ripple, upper pole of the implant and long-term implant ptosis were compared respectively. The complications including hematoma, infection and capsular contraction were also recorded.

RESULTS56 cases were followed up for 2 months to 26 months. The incidence rate of visible implant edge or ripple was 4.0% (1/25 ) in the subfascial group and 29.0% (9/31) in the submammary group, showing a significant difference between them ( PC 0.05). The incidence rate of convex upper pole of the implant was 8.0% (2/25) in the subfascial group and 35.5% (11/31) in the submammary group, showing a significant difference between them ( P < 0.05). Long-term implant ptosis was not found in the two groups. The incidence rate of hematoma was 4.0% (1/25) in the subfascial group and 6.5% (2/31) in the submammary group, infection was not found. The incidence rate of capsular contraction was 8.0% (2/25) in the subfascial group and 12.9% (4/31) in the submammary group, showing no statistical difference between them ( P > 0.05 ).

CONCLUSIONSSubfascial breast augmentation has more clinical advantages compared with submammary breast augmentation, but no evident difference was found in the common complication rate, such as capsular contraction.

OBJECTIVETo investigate the effects of hydrogen sulfide (H₂S) on oxidative stress and endoplasmic reticulum stress (ERS) in a rat model of diabetic cardiomyopathy (DCM).

METHODSThirty male SD rats were randomly divided into control group, diabetes group and treatment group( n = 10). Intraperitoneal injection of streptozotocin was utilized to establish a rat model of DCM. The rats with DCM in treatment group were intraperitoneally injected with NaHS solution. After treated for 12 weeks, the hearts isolated from rats were perfused on a langendorff apparatus. The ventricular hemodynamic parameters were measured. The ultrastructures of myocardium were observed using electron microscopy. The content of malondialdehyde (MDA), the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in myocardial tissue were determined by spectrophotometry. The expressions of C/EBP homologous protein( CHOP), glucose-regulated protein 78 (GRP78) and Caspase 12 at mRNA level in myocardium were detected using RT-PCR.

RESULTSCompared with control group, the cardiac function and myocardial ultrastructure were damaged obviously in diabetic rats. In myocardial tissue, the content of MDA was increased, while the activities of SOD and GSH-Px were decreased. CHOP, GRP78 and Caspase 12 mRNA expressions were increased significantly. Compared with diabetes group, cardiac function and myocardial ultrastructure damage were improved in treatment group. The content of MDA was decreased, while the activities of SOD and GSH-Px were increased significantly. The mRNA levels of CHOP, GRP78 and Caspase 12 were increased.

CONCLUSIONH2S can protect myocardium in diabetic rats, maybe it is related to reduce oxidative stress damage and inhibition of the ERS-induced apoptosis pathway.

Objective:To investigate effects of hydrogen sulfide (H2S) on inducible nitric oxide synthase (iNOS) in kidneys of Type 1 diabetic rats.Methods:Thirty-two male SD rats were randomly divided into four groups:A normal control (NC) group,a diabetes mellitus (DM) group,a NaHS (NaHS+DM) group,and a NaHS control (NaHS) group (n=8 per group).Type 1 diabetes was induced by a single intraperitoneal injection of streptozotocin (55 mg/kg).After successful establishment of models,the rats in NaHS+DM and NaHS groups were injected with NaHS solution (56 μmol/kg) intraperitoneally.Eight weeks later,the activities of total nitric oxide synthase (T-NOS) and iNOS,as well as the level of nitric oxide (NO) were detected in serum and renal tissues,respectively,The activity of glutathione peroxidase (GSH-Px) was determined in renal tissues,The ultrastructures of renal tissues were observed by transmission electron microscope,The protein expression ofiNOS in renal tissues was detected by Western blot.Results:Compared with the NC group,there was no significant difference in the various indexes in the NaHS group (P＞0.05).However,in the DM group,the activities of T-NOS and iNOS,and the level of NO were all increased significantly in serum and renal tissues,while the activity of GSH-Px was decreased in renal tissues.Under the electronic microscope,the thickening of the glomerular capillary basement membrane,the proliferation of mesangial matrix,and the foot fusion were observed.The protein expression ofiNOS was increased obviously in renal tissues in the DM group (P＜0.01).Compared with the DM group,the activities of T-NOS and iNOS and the level of NO were all decreased in serum and renal tissues,while the activity of GSH-Px was increased in renal tissues in the NaHS+DM group (P＜0.01).The renal ultrastructural damages were ameliorated obviously.The protein expression ofiNOS was decreased significantly (P＜0.01).Conclusion:H2S exerts a protective effect on kidney injury in type 1 diabetic rats.The mechanism might be related to inhibition of iNOS activity and protein expression,in turn leading to reduction of NO content in renal tissues.
