ObjectiveTo evaluate the efficacy and safety of spironolactone in treatment NYHA (New York Heart Association) class Ⅰ - Ⅱ heart failure patients. MethodsEighty eight patients with NYHA classⅠ- Ⅱheart failure were randomized to sprionolactone or placebo groups.Patients were assessed by echocardiography and 6-minute walking test (6MWT) ,plasma aldosterone and NT-proBNP were measured before and 6 months after treatment; serum potassium and creatinine were monitored through the study. ResultsThe E/A and E/E' in spironolactone group were significantly lower than those of control group (1.2±0.7 vs. 1.7±0.6, P=0.007;15.2±2.3vs. 17.7±3.0, P=0.000). No differences were observed in left ventricular end-diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF)between two groups after treatment. Left ventricular mass index (LVMI) in spironolactone group decreased after theatment [(117 ±27) g/m2 vs.(112 ± 19) g/m2,P = 0.044]. Plasma aldosterone level in spironolactone group after treatment was significantly lower than that of control group [ ( 157 ± 16) ng/L vs.( 165 ± 16) ng/L, P =0. 021 ]. Although there were no differences in plasma NT-proBNP level between two groups after treatment, it decreased significantly comparing with that of before treatment ( P = 0. 000). No differences were observed in serum potassium and creatinine between two groups after treatment. However serum potassium and creatinine in spironolactone group increased significantly after treatment [ ( 83 ± 18 )pmol/Lvs. (87 ± 22) μmol/L, P =0.047; (4.4 ±0.4) mmoL/L vs. (4.5 ±0.6) mmol/L, P =0. 012]. ConclusionSpironolactone can alleviate cardiac remolding and diastolic function in NYHA classⅠ - Ⅱ heart failure patients.

Objective To investigate the effect of multidisciplinary physician/nurse collaboration care mode in diagnosis and treatment of elderly patients with intertrochanteric fracture.Methods Clinical data of 433 elderly patients with intertrochanteric fracture treated from August 2011 to September 2013 were studied retrospectively.Among them,136 were diagnosed and treated using conventional methods (control group) and 297 using the multidisciplinary physician/nurse collaboration approach (collaboration group).Hospital stay,surgery rate,time from hospitalization and operation,and complications were compared between the two groups.Results Length of hospital stay [(14.8 ± 5.9) d] in collaboration group was not statistically different from that in control group [(16.0 ± 4.7) d,t =0.433,P ＞ 0.05],but surgery rate was improved (72.8％ vs 83.9％,x2 =7.212,P ＜ 0.05),time from hospitalization and operation shortened [(5.6 ± 2.9) d vs (6.9 ± 3.4) d,t =3.096,P ＜ 0.05],and perioperative complication rate reduced in collaboration group compared to control group (all P ＜ 0.05).Conclusion Multidisciplinary physician/nurse collaboration mode is a novel method for diagnosis and treatment of intertrochanteric fracture in the elderly and is associated with improved surgery rate,reduced perioperative complications and early functional recovery.

The perioperative shivering, as one of the adverse reactions during cesarean sections, has many bad influences on the parturients and the neonates. Several studies have already explored in the evaluation methods, risk factors, possible mechanisms, and effective prevention measures for the occurrence of perioperative shivering during cesarean sections. This article will make a review on the basis of literature, hoping to provide a reference for the prevention and treatment of shivering during the perioperative period of cesarean section.

Objective To explore the effect of the physician-nurse-social worker linkage rehabilitation model on the psychological status in patients receiving methadone maintenance treatment(MMT).Methods Ninety-four patients who received MMT were enrolled and randomly divided into experimental group(n = 48)and control group(n = 46).The experimental group received physician-nurse-social worker linkage rehabilitation model intervention,while the control group received conventional methadone treatment service.The anxiety,depression and quality of life of the two groups were evaluated before the intervention,3 months and 6 months after the intervention.Results After 6 months of physician-nurse-social worker linkage rehabilitation mode intervention,the depression status and the anxiety status of the experimental group subjects were significantly improved compared with those before intervention,and both BDI and BAI scores were significantly lower than those of the control group subjects(P＜0.05).Moreover,the proportion of"had depression"and"had anxiety"in the experimental group were significantly lower than those in the control group(P＜0.05).After 6 months of intervention,the QOL-DA score of the experimental group subjects(183.77±8.90)was significantly higher than that of the control group sub-jects(174.76±11.14)(P＜0.01).Conclusion The physician-nurse-social worker linkage rehabilitation model had certain advantages in improving the psychological state of MMT patients,which is worthy of promotion.
