UW solution has bean considered the gold standard for abdominal organ preservation. Celsior solution and HTK solution, with low potassium and low viscosity, are becoming more widely used in the preservation of the kidney, liver and pancreas, and are gradually accepted as an ideal alternative for UW solution. Recent studies have found that addition of trophic factors can attenuate hypothermic ischemic injury to the donor organ, thus improving the preservation outcome. This paper reviews the progress in laboratory research and looks foward to the clinical application of multi-organ preservation solution.

Objective:To observe the influence of a self-designed multiple organ preservation solution,namely Shanghai multi-organ preservation solution(SMO),on the apoptosis of canine renal cortical cells during cold storage and the related mechanism.Methods: Canine kidneys were freshly perfused and separately stored with cold(0-4℃) SMO,hypertonic adenine citrate solution(HC-A),and University of Wisconsin solution(UW solution)(the latter 2 as control).At defined time points during storage,the morphologic changes of renal cortical samples were observed;apoptosis of renal cortical cell was determined by TUNEL;changes of malonldialdehyde(MDA) in cortex homogenate were measured by thiobarbituric acid method;and the activity of superoxide dismutase(SOD) was determined by xanthine oxidase method.Results: Pathologic assessments indicated that the kidney damage was similar in 3 groups within 24 h.The kidney tubular cell swelling and necrosis in SMO group and UW group were slighter than those in HC-A group after stored for 2 days.With the prolongation of storage time,apoptosis increased in all groups,with the apoptotic index of SMO group significantly lower than that of HC-A group(P

Objective To economically investigate tertiary stroke rehabilitation treatment.Methods 3 tertiary rehabilitation networks were set up in Beijing.82 patients with acute cerebrovascular diseases were enrolled into the study according to standardized criteria in all centers and randomized into rehabilitation group and control group.Rehabilitation training was implemented according to standardized procedures.The patients in rehabilitation group were given rehabilitation training in acute stage for 28 days and then underwent long term rehabilitation'program for 6 months in rehabilitation centers or community rehabilitation settings.The patients in control group were only given rehabilitation training in acute stage for 28 days. Altogether 4 evaluations were conducted in one week after the onset and at the end of 1,3,6 months, respectively.Results Significant differences of motor function,ability of daily activities,quality of life evaluation and cost were found in the 1st,3rd and 6th month after the onset of diseases.The rehabilitation group surpassed the control group significantly.At the end of 6 months,the average of Barthel Index of rehabilitation group was 83.18?18.22 while that of control group was 63.69?12.73.At the end of 6 months,total cost of rehabilitation group was(56 420.0?17 831.8)Yuan and that of control group was (64 864.2?18 267.5)Yuan.The rehabilitation group had better cost/effectiveness and cost/utility.There was a significant difference of cost between two groups.The total rehabilitation cost of rehabilitation group was 4613 Yuan,accounting for 15.3%of all the cost.Conclusion The tertiary rehabilitation treatment for stroke patients has achieved better cost/effectiveness and cost/utility.In China pharmaceutical cost constitutes the major part of the stroke therapy while the rehabilitation cost only a small portion,which is significantly different from the situation in developed countries.

Objective To investigate the influences of 4 kinds of collagenase with different degrees of activity on the survival rate,contraction and relaxation functions of isolated rats' myocardiocytes.Methods Rats' myocardiocytes were isolated by enzymolysis with 4 kinds of collagenase with different degrees of activity.The survival rate of myocardiocytes was observed immediately after isolation(D),one hour after loading with calcium(E time point) and 10 minutes after electric stimulation(F time point).The contraction and relaxation functions of myocardiocytes,including contraction amplitude(ph),the proportionality of ph/single cardiocyte length(bl),maximal velocity of contraction(+dL/dt) and maximal velocity of relaxation(-dL/dt),were measured with IonOptix video edge tracker.Results From 203U/mg to 299U/mg,with lowering of the activity of collagenase,the isolation time became longer,the survival rate of myocardiocytes declined 1 hour after loading calcium and 10 minutes after electric stimulation(P

Objective　To provide microanatomic basis for direct microsurgical operation on the region of Dorello's canal. Methods　The structures of the region of Dorellos canal were observed and measured on 30 sides of adult cadaverical heads under microscope. Results　①Dorello's canal was an osteofibrous canal composed of Gruber ligament, petrous apex and the lateral border of the upper part of clivus. The roof of Dorello's canal was mainly composed of Gruber ligament. The maximal distance from roof to bottom of Dorello's canal was 2.14 mm±0.70 mm. ②Abducens nerves passed through the lateral 1/3(56.7%) or intermedial 1/3(43.3%) of Dorello's canal to the cavernous sinus. The nutrient arteries of abducens nerves were originated from the dorsal meningeal arteries, and 83.3% of them traversed Dorello's canal by one stem, medially to abducens nerves. ③The point of abducens nerves entering cavernous sinus was 3.97 mm±1.83 mm posterior to the ascending portion of intracavernous carotid artery, 3.11 mm±0.95 mm medial to the Meckel's cave. Conclusion　In the region of Dorello's canal, the positions of abducens nerves and their nutrient arteries are steady, and they should be protected during operation.

Objective To evaluate the effect of chlorhexidine gargle on respiratory tract infection (RTI)in patients following general anesthesia.Methods From January 2012 to June 2013,94 patients who received general anesthe-sia for removal of vertebral disc were randomly divided into two groups,with 47 cases in each group,control group gargled with normal saline,observation group accepted 2% chlorhexidine gargle.The occurrence of RTI and detec-tion of pharynx pathogens of two groups were compared.Results The incidence of RTI in observation group and control group was 8.51%(n=4)and 23.40%(n=11)respectively(χ2 = 12.95,P <0.05).4 patients in observation group were detected 4 isolates of pathogens,11 patients in control group were detected 26 isolates of pathogens,the detection rate of pharynx pathogens of observation group was lower than control group (χ2 =3.89,P <0.05).The main isolated pathogens were Pseudomonas aeruginosa ,Staphylococcus aureus ,Klebsiella pneumoniae and Esche-richia coli .Conclusion Chlorhexidine gargling can effectively reduce RTI following general anesthesia,it is worthy of clinical application.
