Objective To evaluate the applicability of Mini-Nutritional Assessment(MNA),Short-Form Mini-Nutritional Assessment(MNA-SF)in the malnutrition screening of patients with Alzheimer's disease(AD).Methods MNA and MNA-SF were performed in 267 AD patients.The correlation between the screening results were compared.Results According to MNA,the rates of malnutrition,potential malnutrition,and normal nutritional status were 59.7%,20.9%,and 19.4%,respectively.The sensitivity was 73.4%and the specificity was 60.1%.According to MNA-SF,the rates of malnutrition and normal nutritional status were 70.4%and 29.6%.The sensitivity was 50.6%and the specificity was 92.4%.The screening results of these two tools were significantly correlated(r=0.924,P<0.01).Conclusions MNA and MNA-SF are reliable tools for evaluating the nutritional status of AD patients.While MNA-SF is more convenient and feasible,the combination of these two tools may be helpful.

The intelligent level of the modern medical equipments is higher than before and the automatic calibration circuits are largely used. The control circuit of the intelligent equipments is quite complicated and its working modes have been simplified to four-terminal or double terminal nets. The intelligent medical equipments such as CT, MRI, DR, PET/ CT have more chances to have some "soft" errors that are usually related to the zero-line calibration. In actual use, it can be noticed and performed, and the detecting and servicing for the medical equipments can be much easier than before.

OBJECTIVE To investigate the current situation of sporadic hepatitis E and analyze its epidemiologic feature among inpatients in our hospital from 2002 to 2004. METHODS The clinical records of inpatients with positive results of HEV-IgM and diagnosed for sporadic hepatitis E during the period of Jan 2002 to Dec 2004 were analyzed with epidemiological method. RESULTS Totally 329 inpatients′ HEV-IgM antibody was positive among(4 641) detected inpatients′ sera.There were 239 male inpatients who accounted for 72.64% and(90 female) inpatients who accounted for 27.36% of the total inpatients whose HEV-IgM antibody was positive.There were 272 inpatients,presenting rate of 82.67%,comed from rural areas and 57 inpatients,presenting rate of 17.33%,comed from urban areas.The case rate of sporadic hepatitis E was respectively 4.92%,6.93% and 9.17% from 2002 to 2004. CONCLUSIONS The incidence of hepatitis E is increasing in recent years,in which male inpatients are higher than females′ and rural inpatients are higher than urban ones.

The anesthetists not only pay attention to the exploitation and application of the information resource but also rely more and more on the convenience caused by the informatization. Based on HIS, LIS, and PACS, the Anesthesia information system has been constructed in order to guarantee the quality and safety of the anesthesia. The Anesthesia information system shares the information with HIS and LIS and manages the medical information such as the surgery and anesthesia closely. The paper introduces the notion of the anesthesia information system and its main function and also the predicted effect during the management of the anesthesia information system. Meanwhile, some problem about the application has been mentioned.

Objective: To observe the effect of phophodiesterase 5 (PDE5) inhibitor, sildenafil on morphine withdrawal symptoms in mice. Method: A physical morphine dependent model in mice was established by subcutaneous injection of morphine in gradually increasing doses. After interperitoneal injection of naloxone (0.2mg/kg), withdrawal symptoms including jumping in 15 min, jumping latent period and weight loss were scored to evaluate the response intensity of morphine withdrawal. The effect of sildenafil (15mg/kg, 30mg/kg and 60mg/kg) was observed. Using nitrate reductase method to detect NO (nitric oxide) content in the blood and brain of mice. Result: Morphine withdrawal symptoms were aggravated by 3 different dosage of sildenafil and assumed good dose-dependent manner. NO content in blood increased after 30mg/kg sildenafil, which had no effect on NO content in brain of mice. Conclusion: Morphine withdrawal symptoms can be aggravated by sildenafil, which has also influence on blood content of NO, but has no influence on NO content in brain.

As the base for the healthy development of civil medical equipment industry,the independent developing ability has attracted extensive attention.Firstly,medical equipment enterprises were divided into 5 modes according to their independent developing ability.Then the fuzzy evaluation method was utilized to evaluate them so as to correctly know the independent developing ability of medical equipment industry in our country.The evaluation shows that the brand value of the civil medical equipment is generally low.

Objective To observe the effects of dorsiflexion ankle foot orthotics (d-AFO) on pelvic control of hemiplegic patients by analyzing the time-space gait parameters and 3D pelvic motion parameters.Methods Fifteen hemiplegic patients (14 male and 1 female) were enrolled in this study.The time-space gait parameters and pelvic 3D motion parameters were collecte with a Motion Analysis System while the patients were asked to walk under 3 conditions:wearing d-AFO (5°dorsiflexion),f-AFO (0°dorsiflexion) or barefoot.Results It was found that,while wearing d-AFO,the velocity,the paralyzed step length and the nonparalyzed step length were significantly increased,and the step width was significantly decreased when compared with those while walking barefoot (P ＜ 0.05).Comparison between wearing d-AFO and f-AFO showed that the sagittal and coronal plane inclinations,but not the transverse rotation of pelvis were significantly decreased when wearing the d-AFO (P ＜ 0.05).Conclusions d-AFO can significantly improve pelvis control and increase gait stability in hemiplegic patients.

Objective To determine the optimal volume of plasma that should be used to perfuse through the portal vein (PV) to washout preservation fluid in retrograde reperfusion during liver transplantation.Methods The clinical data of S0 patients who underwent orthotopic liver transplantation (OLT) using retrograde reperfusion via the inferior vena cava (IVC) in our hospital from January 2011 to October 2013 were retrospectively analyzed.The patients were divided into two groups based on the volume of plasma infused via the PV to flush out the preservation fluid.Group 1:27 patients who received 400 ml,and Group 2:23 patients who received 1 200 ml.The preoperative and intraoperative data of the two groups were compared and analyzed.The serum concentrations of K+,Na+,Ca2+,mean arterial pressure (MAP) and pH were continuously monitored in the transplant recipients at different time points during liver transplantation.In addition,for patients in Group 2,the serum K +,Na + and Ca2 + concentrations in the samples of effluent fluid from the liver grafts were collected via the anastomotic stoma of the infrahepatic IVC and measured after infusion of 200 ml,400 ml,600 ml,800 ml,1 000 ml,or 1 200 ml of plasma.Results There were no significant differences in the preoperative and intraoperative data between the two groups.The plasma concentration of K + in Group 1 was significantly higher than that of Group 2 at 1 min after PV revascularization (T3) [(4.31 ± 0.54) mmol/L vs (3.96 ± 0.58) mmol/L,P ＜ 0.05],while the pH was significantly lower in Group 1 than that of in Group 2 (7.26 ± 0.02 vs 7.30 ± 0.04,P ＜ 0.05).The plasma Na + and Ca2 +concentrations,as well as the MAP,were not significantly different between the two groups at this time point.In group 2,no significant changes were observed in Ca2+ concentration in IVC blood following perfusion of 200 ml plasma.The insignificant changes in Na + after perfusion of 400 ml of plasma and for K + after 800 ml of plasma (P ＞ 0.05).Conclusions The electrolyte concentrations,blood pressure and arterial blood pH were fairly normal after resuming flow with PV revascularization after a perfusion volume of 800 ml of plasma.This volume was the most appropriate perfusion volume,balancing its effectiveness with economy to wash out any UW solution during OLT using retrograde reperfusion.
