OBJECTIVE:To observe the influence of capecitabine combined with radiotherapy on postoperative survival rate, relapse rate and survival quality of elderly patients with rectal cancer at Ⅱ-Ⅲ stage. METHODS:110 patients with rectal cancer atⅡ-Ⅲ stage were selected and randomly divided into control group and observation group with 55 cases in each group. Both group received radical resection of rectal carcinoma. Control group was given three dimensional conformal radiation therapy(3DCRT)af-ter operation;observation group was additionally given capecitabine 1 500 mg/m2,d1-14,qd,on the basis of control group. A treatment course lasted for 21 d,and both groups received 2 courses of treatment and followed up for 3 years. The survival rate and metastasis and recurrence rate of 2 groups were compared as well as KPS score before and after treatment. Toxic reaction of 2 groups was also observed. RESULTS:The follow-up total survival rate and disease-free survival rate of observation group were 89.09%and 76.36%,which were significantly higher than 74.55%and 54.55%of control group;the distant metastasis rate and lo-cal recurrence rate were 12.73% and 5.45%,which were significantly lower than 30.91% and 21.82%,with statistical significance (P<0.05). KPS score of 2 groups were increased significantly,between 2 groups before and after treatment ,with statistical signifi-cance(P<0.05);Comparison between groups(P>0.05). There was no statistical significance in the incidence of nausea and vom-iting,diarrhea and urinary tract reaction between 2 groups (P>0.05);but the incidence of bone marrow arrest in observation group was significantly higher than control group(P<0.05). CONCLUSIONS:Capecitabine combined with 3DCRT can effectively improve postoperative distant survival rate of patients with rectal cancer at Ⅱ-Ⅲ stage,and reduce the metastasis and recurrence risk;do not lower life quality and induce serious adverse reactions.

Objectives To analyse the predisposing cause and clinical manifestasion of diabetic ketoacidosis (DKA) complicated with multiple organic failure (MOF),in order to diagnose early and management timely.Methods 537 diabetic patients admitted in our hospital from 1997 to 2000 were included in this cases retrospective study. 182 cases of them complicated with DKA or DKA complicated with MOF (58) were further analyzed by cause, clinical manifestation, number of organs in MOF and the prognosis. Results Analysis showed that the main cause of MOF in DKA patients was infection (84 5%). The higher incidence of MOF in older DKA patients than those of younger. The possible involved organs in MOF were kidney, heart and brain etc. Involving organs of MOF were much, the mortality was closely correlated with the number of involved organs. Conclusions The possible way to reduce the incidence of MOF in DKA patients is intensive preventing and treating infection. To avoid MOF occurring in DKA patients, complications of kidney, heart and brain should be timely diagnosed and managed.

BACKGROUND: Learning memory disorder is one of the major manifestations of aging. The model of aging induced by D-galactose is a commonly used animal model in recent years, and long-term D-galactose exposure may cause nerve cell morphological changes in animals.OBJETCIVE: To observe spatial learning memory behavior during Dgalactose-induced aging process in order to further explore in vivo evoked long-term potentiation in hippocampus dentate gyrus and synaptic morphological changes in hippocampal CA3 region.DESIGN: Randomized controlled observation.SETTING: Anatomical Teaching and Research Secti , Shanghai Second Medical University; Department of Physiology, Shanghai Traditional Chinese Medicine University.MATERIALS: The experiment was carried out at the Physiological Laboratory of Shanghai Traditional Chinese Medicine University between August 2000 and April 2001. Totally 22 male Wistar rats of 3-month birth age were included and randomized into normal group and D-galactose group with 11 rats in each group. D-galactose was produced by Shanghai No. 2 Chemical Reagent Factory, Morris water maze was home-made by the Institute of Geriatrics, Shanghai Traditional Chinese Medicine university.METHODS: Rats were subjected to hypodermic injection of 1 mL normal saline every day in normal group, or D-galactose of 800 mg/kg daily for 6consecutive weeks in D-galactose group. Rat spatial learning memory behavior was assessed by the latency of Morris water maze; hippocampal dentate gyrus community potentials evoked by monopulse stimulation on perforating fibers were recordedin vivo; meanwhile, the amplitude of monopulse evoked potentials was determined before and after high frequency stimulation, with the amplitude before high frequency stimulation taken as baseline. Transmission electromicroscope was applied in combination with imaging analysis to observe synaptic morphology and structure in rat hippocampal CA3 region. Water labyrinth latency was compared using the variance analysis of repetitive survey design, t-test was used to compare the differences of peak potential latency of community potentials at various time points after long-term potentiation. Moreover, inducing rate of longterm potentiation was compared by χ2-test, XY-540 type biological imaging processing system was used to analyze electromicroscopic pictures, and all available data were analyzed with t-test.MAN OUTCOME MEASURES: [1] Main outcomes: Changes of Morris water maze latency, as well as inducing rate of long-term potentiation and community potentials. [2] Secondary outcomes: Synaptic morphological and structural changes in hippocampal CA3 region.RESULTS: Totally 22 rats were enrolled in this study, with no one lost during water labyrinth test, but one rat in both normal group and D-galactose group died during electrophysiological experiment. Finally 3 rats were randomly selected from each group for electromicroscopic observation. [1]Comparison of the latency for Morris water maze: In contrast with that of normal group, latency for seeking submarine platform was obviously prolonged in D-galactose group [(14.77±10.10), (51.36±12.45) s, P ＜ 0.05].[2] Comparison of evoked potential in hippocampus dentate before high frequency stimulation: The two groups did not obviously differ in community potential amplitude and community potential latency [(1.05±0.47),(0.91±0.41) mV; (5.46±2.09), (5.38±2.26) ms; P ＞ 0.05]. [3] Inducing rate of long-term potentiation in hippocampal dentate gyrus: Compared to that of normal group, inducing rate in D-galactose group obviously reduced after high frequency stimulation (80%, 20%, χ2=7.20, P ＜ 0.01). [4] Comparison of community potential ratio at different time points after high frequency stimulation: Compared to that of normal group, it was notably reduced in D-galactose group at post-stimulation 20, 30, 60 minutes, respectively (1.104±0.196, 0.919±0.162; 1.354±0.212, 0.999±0.219; 1.236±0.174,0.875±0.311; P ＜ 0.05). [5] Comparison of synaptic struc tural parameters in hippocampal CA3 region: Compared to that of normal group, postsynaptic dense bodies became thickened in hippocampal CA3 region of D-galactose group [(40.60±18.26), (26.35±8.15) nm, P ＜ 0.05], the synapse gap increased [(17.69±6.28), (26.95±5.67) nm, P ＜ 0.05] while synaptic active zone was shortened [(265.13±76.50), (229.13±90.68) nm, P ＜ 0.05].CONCLUSION: Hypodermic injection of D-galactose does harm to rat spatial learning memory by reducing the long-term potentiation, inducing rate in rat hippocampal dentate gyrus, attenuating the increase of long-term potentiation-evoked potential amplitude, and even remarkably changing the synaptic ultrastructure in rat hippocampal CA3 region. It suggests that Dgalactose inhibits the long-term potentiation at hippocampal dentate gyrus and affects synaptic structure in hippocampal CA3 region, which is considered as the basis of spatial learning memory behavioral disorder.

Objective To investigate the effects of sensorimotor therapy on patients with knee osteoarthritis.Methods Ninety-two patients with knee osteoarthritis were divided into a treatment group and a control group by using random digits table. Both groups received conventional rehabilitation therapy, including knee isometric and isotonic contraction training, ultrashort wave diathermy as well as aerobic exercise. The treatment group was also administered with sensorimotor training, in addition to the conventional training,including the muscle strengthening and control training of quadriceps and hamstring muscle using sling exercise therapy system and on the Thera-band mattress. The visual analogue scale (VAS) for pain, manual muscle testing and knee range of motion as well as the Japanese Orthopedic Association knee function evaluation form were used to evaluate the patients. Results There was no statistic difference between the 2 groups before treatment, with regard to the evaluation parameters used in this study. After 2 months of treatment, both groups improved significantly (P ＜0.05),with the treatment group improved to a significantly greater extent (P ＜0.05). Conclusions Sensorimotor training in addition to the conventional rehabilitation treatment can further relieve the pain of patients with knee osteoarthritis joints arthritis and improve the function of patients with knee osteoarthritis.

The regional medical information system calls for regional information resources and hospital-level information resources be interconnected and intercommunicated.To meet this requirement,a HL7 CDA-based solution was proposed based on analysis of the current hospital information resources management.An information resources service portal was built to harmonize the management of both new and old resources,and the hierarchy management based on information granularity.The technical implementation of the system is compliant with the SOA architecture and health information standards.This ensures the interconnection and intercommunication between inner information and outer one,and uses information resources in an efficient,reasonable and safe manner.
