Objective: To investigate the effects of Shen-Mai injection(SM) on perfusion and oxygenation of intestinaltract during repeffusion in shocked rabbits. Methods:Twenty-one rabbits were divided into control group (Ⅰ,n = 6), shock-repeffusion group ( Ⅱ, n = 9) and SM group ( Ⅲ, n = 6). Intestinal intramucosal pH (pHi) of the sigrnoid colon and portalvein blood gas was observed before shock, at 1 hour after shock, 1 hour and 2 hours of reperfusion. Results: pHi and portal vein pH in group Ⅱ were significantly lower than those in group Ⅰ (P < 0.01), but portal vein increased obviously during reperfusion. There was a good linear positive correlation between pHi and portal vein pH. Portal vein in group Ⅱ was greater than that in group Ⅰ and had anegative correlation with pHi. pHi and portal vein pH of group Ⅲ increased signifi- cantly compared with those of goup Ⅱ ( P < 0.05), while of group Ⅲ returned to the level of group Ⅰ . MAP and CO of group m were higher than those of group Ⅱ after 1 hour or 2 hours reperfusion (P<0.05).CO of group m remained at a high level during reperfusion. But SVR of group Ⅲ was lower than that of group Ⅱ during reperfusion. Conclusion: SM im-proves perfusion and oxygenation of intestinal tract during reperfusion.

Objective To explore the effect of comorbidities on the surgical outcomes of elderly patients with hip fracture. Methods The Age,gender,weight,type of fracture,preoperative comorbidities and surgical outcomes of 117 patients aged 80 yr or over who undergoing hip fracture surgery in our hospital were recorded. Patients were divided into rehabilitation group and postoperative in-hospital death group ac-cording to surgical outcomes. The potential predictors of postoperative in-hospital death were identified by univariate model and were then entered into multiple Logistic regression analysis. Results Twenty three patients(19. 7%)had no comorbidity,94 patients(80. 3%)had one or more comorbidities. Ten patients(8. 5%)died in hospital after the operation. Predictors of postoperative in-hospital death were preoperative respiratory diseases and three or more comorbidities. Conclusion Surgical outcomes of elderly patients with hip fracture may be predicted by analysing preoperative comorbidities. Preoperative preparations must be sufficient in order to ensure successful operation.

Objective To investigate the relationship between refractory hypertension and renal hemodynamics in end stage renal diseases (ESRD) patients.Methods ESRD patients were classified into:patients with refractory hypertension (group A) and patients with normal blood pressure(group B).Renal hemodynamic indices were ex- amined by duplex ultrasonography.Fasting serum lipid (TC,TG,HDL-C,LDL-C,Lp(a),ox-LDL) and serum parathyroid hormane (PTH) were determined in all patients.Results Significant differences were found in renal hemodynamic indices such as peak systolic velocity (PSV),mean flow velocity (MV),pulsatility index (PI),renal- aortic ratio (RAR) and in clinical index such as Lp(a) and ox-LDL between the two group.Refractory hyperten- sion patients had lower renal hemodynamic indices and higher Lp(a) and ox-LDL levels than in patients with con- trolled BP.Logistic regression analysis revealed that refractory hypertension was related with PSV,EDV,Pl and RAR,but not relevant with sex,age,dialysis time,hematocrit,BUN,creatinine,TC,TG,HDL-C,LDL-C, PTH,MV and RI.Conclusion Atherosclerotic renal artery stenosis and severe disorder in renal hemodynamics is likely the cause for refractory hypertention in ESRD patients.The rise of serum Lp(a) and ox-LDL might acceler- ate renal artery atherosclerosis.
