Objective: To investigate the impact and its possible mechanism of hydrogen sulfide (H2S) on myocardial collagen remodeling in experimental rats with diabetic mellitus (DM).
Methods: Rat’s DM model was established by intraperitoneal injection of STZ at 40 mg/kg. A total of 40 SD rats were randomly divided into 4 groups:Control group, DM group, DM+NaHS group, in which NaHS worked as exogenous donor of H2S and NaHS control group. n=10 in each group, all animals were treated for 8 weeks. The cardiac collagen deposition was observed by Masson staining, protein expressions of cardiac collagen types I, III, IV and transforming growth factorβ1 (TGF-β1), connective tissue growth factor (CTGF) were examined by Western blot analysis.
Results: Compared with Control group, DM group showed increased protein expressions of cardiac collagen types I and III, up-regulated expressions of TGF-β1 and CTGF, P<0.05;while the expressions of collagen type IV were similar between 2 groups. Compared with DM group, DM+NaHS group presented reduced cardiac collagen expression, decreased expression of collagen types I and III, down-regulated expressions of TGF-β1 and CTGF, P<0.05;while the expressions of collagen type IV were similar between 2 groups.
Conclusion: H2S may improve the myocardial collagen remodeling in experimental DM rats, the mechanism might be related to the down-regulation of TGF-β1 and CTGF expression.

Background and purpose:Lung cancer is the leading cause of cancer-related deaths worldwide. Approximately 15%of all histological types consist of small cell lung cancer (SCLC). Chemotherapy is one of the major treatment methods. Though the current front-line standard chemotherapy regimen for SCLC is active in most SCLC cases, however, the disease recurs shortly after the ifrst successful treatment with multi-drug resistance phenotype. Our previously study showed that zinc ifnger protein X-linked (ZFX) was overexpressed in SCLC cells. This study aimed to investigate the expression of ZFX in SCLC tissues, and to clear their possible associations with clinical parameters and provide basis for therapy of SCLC. Methods:A total of 98 surgical specimens of small cell lung cancer were collected. The expression of ZFX was examined by quantiifcational real-time polymerase chain reaction in 78 specimens taken from patients with complete clinical data. Results:The expression of ZFX was signiifcantly increased in extensive stages than in limited stages. The expression of ZFX was associated with tumor stage, the sensitivity of chemotherapy, and survival times (all P<0.05), no data was found correlated with gender and ages (P>0.05). Conclusion: ZFX expression might be associated with the development of SCLC, and may be a potential prognosis predictor.

Objective To approach the correlation of the left ventricular function in elderly patients with acute myocardial infarction (AMI) at low-risk factor. Methods Forty-five elderly patients hospitalized for AMI were registered, including 20 patients who were underwent emergency percutaneous coronary intervention (PCI) after the onset of AMI and 25 patients who received conservative non-invasive therapies. These 45 cases all received echocardiography(ECHO) examination in the 4th and 24th week after acute myocardial infarction. Results In the PCI group, end-diastolic volume index (EDVI) and end-systolic volume index (ESVI) had significant difference (P0.05) after therapy; WMSI was higher than PCI group (P

OBJECTIVE To summarize the clinical experience of endoscopic thyroidectomy via suprasternal approach. METHODS Endoscopic thyroidectomy via suprasternal approach was performed in 35 patients with ultrasonic scalpel. RESULTS Operations were successfully performed in 35 patients.
