Objective To investigate the effect of cardiac resynchronization therapy on improving heart function and reversing left ventricular remodeling in chronic heart failure patients. Methods Eleven patients with NYHA class Ⅲ to Ⅳ heart failure, ejection fraction ≤35% and QRS duration ≥130 ms were implanted synchronous biventricular pacemaker. Serial assessment was performed before and up to 1-36 months after pacing. Results There were significant improvement of LVEF、 LVFS; and decrease in MR、 LVED and QRS duration. The NYHA class of heart function was improved from Ⅲ-Ⅳ to Ⅰ-Ⅱ. Six-minute hall walk distances were also improved. Conclusion For patients with NYHA class Ⅲ to Ⅳ heart failure and ventricular conduction delay, cardiac resynchronization therapy could reverse left ventricular remodeling and improve heart function.

Objective To establish a rat model of pulmonary hypertension induced by left-to-right shunt and explore the influence of high pulmonary blood flow on pulmonary vascular collagen remodeling.Methods Abdominal aorta and inferior vena cava shunting was produced in rats. Pulmonary artery meanpressure (PAMP) of each rat was measured by using a right cardiac catheterization.Pulmonary artery collagen Ⅰ and Ⅲ were detected using immunohistochemisty.Results After 11 weeks of shunting the Qp/Qs was 3.3∶1.0,indicating a large shunt. Pulmonary artery mean pressure was increased as compared with controls[(23.0?0.9) mm Hg vs (15.7? 1.1) mm Hg,P

Objective:To investigate the prognostic values of tumor–stroma ratio and tumor-infiltrating lymphocytes in colorec-tal cancer. Methods:A total of 218 stageⅡorⅢprimary colorectal cancer patients were analyzed for the tumor–stroma ratio (TSR) and tumor-infiltrating lymphocytes (TIL) by using HE stained histological sections. The relationship between TSR and clinicopatholog-ic variables and the difference in clinical outcomes of different groups were also analyzed. Results:Overall survival rates for the stro-ma-low group were significantly higher than the stroma-high group in stagesⅡandⅢcolorectal cancer (P<0.05). However, the differ-ences in TSR were not correlated with clinicopathologic features such as gender and age (P>0.05). Overall survival rates of patients with high TIL were significantly higher than patients with low TIL (P<0.05). Patients with high TIL had notable better prognosis than patients with low TIL (P<0.05) in the stroma-low group. Conclusion:TSR and TIL are independent prognostic factors for stagesⅡandⅢcolorectal cancer. The combined estimates of TSR and TIL in routine pathology diagnoses may provide more evidence to predict the prognosis of stagesⅡandⅢcolorectal cancer.

Objective To compare the surgical effects of transurethal enucleation of prostate (TUEP)with transurethal resection of prostate (TURP) by a retrospective analysis of clinical data.Methods The patients in this study were divided into the groups of TUEP (enrolled in 2010 and 2011,n =77) and TURP (enrolled in 2009,n =27) with prostate larger than 60 g and smaller than 60 g respectively.Comparisons were made between the two groups in operation time,blood loss volume and weight of resected prostate.Results In the group of patients with prostate larger than 60 g,there was no significant difference in prostate weight ((88.5 ± 9.2) g vs.(107.0 ± 15.30) g,P =0.255),operation time ((91.5 ± 8.8) min vs.(118.3 ± 20.2)min,P =0.083),and weight of resected prostate ((48.0 ± 4.6) g vs.(58.4 ± 5.4) g,P =0.32) between the TUEP (53 patients) and the TURP (12 patients) groups.There was significant difference in blood loss ((110.0 ± 16.4) ml vs.(193.3 ± 22.3) ml,P =0.011) between the two groups.In the group of patients with prostate smaller than 60 g,there was no significant difference in prostate weight ((43.1 ± 3.2) g vs.(36.8 ± 3.4) g,P =0.072),operation time ((62.7 ±6.8) min vs.(69.3 ±6.2) min,P =0.431),blood loss ((56 ± 5) ml vs.(110±20) ml,P=0.082),and weight of resected prostate ((26.3 ±2.4) g vs.(23.6 ±2.1) g,P =0.291) between the TUEP (24 patients) and the TURP (15 patients) groups.Conclusion Compared with TURP,TUEP has the advantages of less blood loss in the treatment of patients with prostate larger than 60 g.With the improvement of surgeon' s experience and development of operation techniques,TURP will be replaced by TUEP.In the treatment of patients with prostate smaller than 60 g,the operation modality can be chosen by the surgeon based on his experience and proficiency.

A 18-year-old male patient's case was diagnosed as Degos'disease with pathognomonic skin lesions,accompanied by small bowel perforation,and reported here. Skin histopothological test show that the typical wedge-shaped necrobiosis and lymphocyte inflammatory infiltration. Vessels showed narrowing and thrombosis,with lymphocyte infiltration. Degos'disease is a systemic necrotizing vasculitis. Skin biopsy can confirm its diagnosis. Severe systemic complication should be prevented. Degos'disease should be considered in the differential diagnosis of skin lesions associated with systemic involvement.

Objective To evaluate the status of self-efficacy and its influencing factors in adult patients with low vision,then explore an effective approach to improve their self-efficacy levels.Methods Seventy adult patients with low vision were sampled by random number table method.General social-demographic questionnaire and self-efficacy questionnaire were used to investigate these patients' general information and self-efficacy.Seventy pieces of questionnaires were issued and returned with the valid rate of 100%.Results The total score of self-efficacy in seventy adult patients with low vision was(16.25:±:1.93) points,92% of patients had a low level of self-efficacy.The influencing factors of self-efficacy in adult patients with low vision were the attitude toward disease,mental status and gender.Conclusions The selfefficacy in patients with low vision was affected by many factors at different levels,so we should focus on main influencing factors to adopt corresponding nursing measures in order to improve self-efficacy of adult patients with low vision.
