Objective To evaluate the effect of nasointestinal tube in patients receiving mechanical ventilation.Methods Patients receiving mechanical ventilation were randomLy divided into two groups.The two groups were isocaloric and isonitrogen.The study group used nasointestinal tube feeding.The control group used nasogastric tube feeding.Nutrition status,ventilator days,aspiration incidence and pneumonia incidence were measured.Results 178 patients receiving me- chanical ventilation were divided into two groups.The study group showed reduction in aspiration incidence and pneumoni- a incidence.Other measurements showed no significant difference.Conclusion Nasointestinal tube feeding could reduce aspiration and pneumonia incidence in patients receiving mechanical ventilation.

Radiotherapy is one of the most important treatments for glioma; however its therapeutic effect is unsatisfying. Timing, accurate target outlining, a total dose higher than 60Gy, conformal modulating radiotherapy and combined chemotherapy and targeted therapy are important factors in improving the outcome of radiotherapy.

This paper describes the basic principles of optical analysis measurements,such as colorimetry,spectrophotometry,fluorometry,fluorescence spectrophotometry and scatter,and their typical applications to medical analysis instrument.The quality control of the optical analysis instrument and their development are also discussed.

Th17 cells play an important role in the pathogenesis of various immune-mediated diseases,including psoriasis,rheumatoid arthritis,multiple sclerosis,inflammatory bowel disease,asthma,and so on.The discovery of Th17 cells has offered scientists a new insight into the etiology and treatment of a broad spectrum of diseases.This article presents an overview of the differentiation,cytokine expression and trafficking of Th17 cells.

Objective To improve the clinical use of donor kidneys having abnormal blood vessels.Methods The kidneys with abnormal blood vessels were transplanted after vessel reconstruction was made. Various techniques were used for different types of abnormal arteries and veins.Results Of 78 donor kidneys with abnormal arteries (23 kidneys also have abnormal veins) been transplanted, 77 grafts excreted urine immediately and the recipients' blood creatinine level were normal was weeks after transplantation. During a period of one-year follow-up, no vascular complication was observed. One kidney was resected because of uncontrolled bleeding secondary to poor venous return. Conclusion Donor kidneys with vascular abnormalities can function well after proper reconstruction.

Objective To investigate the changes in pharmacokinetics of propofol and propofol concentration in the brain induced by normovolemic hemodilution ( NHD) . Methods Thirteen healthy male mongrel dogs weighing 10-15 kg were randomly divided into 2 groups: control group ( n = 7) and NHD group ( n = 6). The animals were anesthetized with intravenous diazepam 0.5 mg?kg-1 and ketamine 5 mg?kg-1 . The femoral artery and vein were cannulated. Lactated Ringer's solution was infused at 5-7 ml ? kg-1 ? h-1 . 30 min after induction of anesthesia NHD was conducted by removing blood from femoral artery and replacing it with 6% hydroxyethyl starch (HES) until Hct was reduced to 25% . Propofol was then infused at 10 mg?kg-1 ?h-1 for 30 min after NHD. Arterial blood samples were taken immediately before and at 1, 2, 5 , 10, 15, 20, 30, 31, 32, 35, 40, 50, 70, 90, 120, 150, 180, 240 and 300 min after propofol infusion was started for determination of plasma propofol concentrations. One week later the same NHD was repeated. Propofol was administered by TCI via Graseby 3500 infusion pump incorporated with Stanpump TCI software. Target plasma propofol concentration was set at 5 ?g?ml-1 . Arterial blood and CSF samples were obtained at 5, 15, 30, 45 and 60 min after the start of propofol infusion for determination of plasma propofol concentration ( bound and free) , plasma free propofol concentration and CSF propofol concentration. At the end of 60 min, after the collection of blood and CSF samples, brain tissue was obtained from the cerebral cortex of right frontal lobe for determination of brain propofol content. ECG, BP, arterial blood gases and body temperature were monitored during experiment.Results The plasma propofol concentrations were significantly lower during and after propofol infusion at 10 mg? kg-1 ? h-1 in NHD group than in control group ( P

Objective To compare the effectiveness of patient-controlled propofol sedation (PCS) against propofol sedation with TCI during epidural anesthesia. Methods Thirty-two ASA Ⅰ -Ⅱ patients (18 male , 14 female) aged between 23-71 years, undergoing lower abdominal surgery or surgery on lower limb were randomly divided into two groups: PCS group ( n =16) and TCI group ( n = 16). Propofol sedation was started when epidural anesthesia was shown to be satisfactory. In PCS group a loading dose of propofol 0.5?g?kg-1 was given. The bolus dose was 0.3mg?kg-1 and the lock-out interval 2 min. There was no background infusion of propofol. In TCI group the initial target concentration of propofol was set at 1. 5?g?kg-1 target concentration was adjusted according to OAA/S score which was maintained at 3 during operation. Radial artery was cannulated and arterial blood samples were taken for determination of blood propofol concentration before and 5, 15, 30, 45 min after incision. OAA/S score was evaluated every 5 min and at the same time BIS and 95% SEF were recorded. The total amount of propofol infused during operation was recorded and whether the patient was satisfied with sedation was inquired. Results All patients expressed great satisfaction with the sedation in both groups. In PCS group the level of sedation was lighter and less propofol was consumed than in the TCI group. (2.5mg?kg-1 ?h-1 vs 3.8mg?kg?h-1, P

NFC is characterized by its short transfer distance, low energy consumption, multiple operation model, high safety, portability, good interconnection, and compatibility with RFID.It can thus be considered as the updated edition of RFID.The significance to innovate the service of library using combined NFC and RFID was therefore elaborated with some suggestions put forward for constructing the smart library.
