Objective To investigate the risk factors associated with feeding intolerance in very low birth weight infants (VLBWI) and to investigate the beneficial factors for preventing feeding intolerance.Methods Retrospectively analysis was carried out in 151 VLBWI cases in our hospital from January 2005 to November 2010.Logistic regression analysis was performed to find the risk factors of feeding intolerance.Results The overall rate of feeding intolerance in VLBWI was 47.7 ％ (72/151).Dysporia and infection were associated with feeding intolerance in VLBWI (Wald x2 =7.748 and 4.555,P =0.05 and 0.033 respectively).Gender,multifetation were not associated with feeding intolerance(Ps ＞0.05).Conclusion The feeding intolerance is associated with dysporia and infection in VLBWI.

We carried out the stress relaxation and creep experiments on the aorta ascendens of five fresh dead bodies of normal chinese men who had died from impetuous trauma on the head. The stress relaxation and creep data and curves of the aorta ascendens were obtained. Then regression analysis was performed to get the reduced stress relaxation and creep functions. Finally, we analyzed and discussed the results of the experiment.

Objective To investigate the value of CT virtual endoscopy(CTVE) and multiple plane(reconstruction)(MPR)for preoperative staging of rectal cancer.Methods Forty-five patients with rectal(cancer) were examined by CTVE and MPR to determine the preoperative staging,and the reselts were compared with CT.Results For evaluation of intramural invasion,the accuracy rate of CTVE and MPR was 86.7%(39/45),pelvic CT was 66.7%(30/45)(P

OBJECTIVE To estimate the prevalence of nosocomial infections(NI) of our hospital.METHODS With a method of transversal sectional investigation,choosing one day each year during from 2004 to 2006,we investigated all these days′ hospitalized patients,using the same criteria,collected the questionnaires,sorted out and anayzed the nosocomial infection cases.RESULTS Among 2738 investigated patients,the prevalence rate of nosocomial infection was 6.49%,5.70% and 4.47% respective.CONCLUSIONS The respective prevalence rate of NI are consistent with the month and the year survey results.

Objective To study the protective effect of Xinfuli Granula(XG) on acute and chronic cardiac failure in cats and rats. Methods The cat models of acute cardiac failure were established by injecting pentobarbital. Then the cat models were given XG through duodenum. After medication,hemodynamics parameters such as heart rate(HR),mean arterial pressure(MAP),left ventricular systolic pressure(LVSP),left ventricular end-diastolic pressure(LVEDP),+ dp/dtmax and cardiac output(CO) in cats were determined. The rats were divided randomly into 5 groups:the control group,the model group,the positive control group,and high-dose and Low-dose XG groups. The rat models of myocardial injury were induced by isoproterenol(20 mg/kg). The normal group and the model group were treated with normal saline(10 mL/kg) orally,the positive contral group were treated with cedilanid(0.2 mg/kg) by intravenous,the high-and low-dose XG groups were orally treated with XG(10 g/kg and 5 g/kg respectively),and the propranolol group was orally treated with propranolol(4 mg/kg),once a day for successive 8 days. Animals were sacrificed on the 9th day,then the heart was taken out and the cardiac index was calculated. The pathological changes in myocardial cells of the rats were observed under electron microscope. Results XG had no effect on hemodynamics of cats with acute cardiac failure,but had obvious protective and therapeutic effect on isoproterenol-inducedmyocardial injury and myocardial ischemia of rats. Conclusion Xinfuli Granula has good preventive effect on isoproterenol-induced myocardial injury and sub-acute cardiac failure of rats,but has no effect on acute cardiac failure of cats.

OBJECTIVE To focus on the diagnosis,treatment and prevention of central venous catheter(CVC)-related bloodstream infections(CRBSI)in clinical practice.METHODS The related articles within the nearest 10 years were reviewed,which published in the domestiec and foreign academic journals,at the same time,the related monitoring data of the hospital were analyzed.RESULTS Highlights on the diagnosis,treatment and prevention of CRBSI:for the patients with CVC,the possibility of the CRBSI should be considered,as soon as a high fever was found,and it could not be explained with the non-infectious causes.Infection occurring time and pathogen were different between the general catheters and the anti-infective catheters.The effect of the anti-infective catheters was limited.To pull out the catheters was one of the most effective treatment measures.CONCLUSIONS Prevention of CRBSI:the indications of CVC intubation should be undisputed.Silicone catheter should be used.When the catheter is predicted to be indwelling more than 5 days,anti-infective catheters should be chosen.To insert CVC at the subclavian vein instead of the femoral vein.To care the hub and keep the puncture point dry and do disinfection well.The health care workers should be trained.

Objective To study the extracellular signal-regulated kinase 1/2(ERK1/2) expression of renal cells in epilepsy rats induced by kainic acid,and elucidate the mechanism of renal injury caused by epilepsy.Methods 70 male Wistar rats were randomly divided into two groups:epilepsy group and control group,35 rats in each group.Rat epilepsy model was prepared by injection of kainic acid into amygdala under three-dimensional positioning devices.At different time points(0,2,6,12 and 24 h) after epilepsy spasm,the renal tissue specimens were immediately prepared for immunohistochemistry.The ERK1/2 expression of rat renal cells was calculated and compared with control group.Results The ERK1/2 expression(gray value) of renal tubular epithelial cells in epilepsy rats began to increase gradually after epilepsy spasm.It reached peak at 6 h after epilepsy spasm.The ERK1/2 expression of renal tubular epithelial cells in epilepsy rats was significantly higher than at 0 h(P0.05).There were no major pathological changes in kidney of rats with epilepsy stained with HE.Conclusion ERK1/2 activation may have important role in the renal injury caused by epilepsy.Inhibition of the activation of ERK1/2 may lead to the renal protection.
