Objective To evaluate the changes of the lower limber somatosensory evoked potentials (SEPs) in patients with delayed encephalopathy after acute carbon monoxide poisoning.Methods The tibial nerve SEPs were performed in 32 healthy adults and 40 patients with delayed encephalopathy after acute carbon monoxide poisoning. Wave N22, P40, N50, P60, N75 latency and N22～P40 interpeaklatencies were measured, respectively.Results 30 patients (75%) indicated abnormalities of tibial nerve SEPs. The latencies of cortical potential of wave P40 [(41.92?2.49)ms], N50 [(52.13?4.29) ms], P60 [(64.37?4.98) ms] and N75 [(80.84?4.73)ms] in patient group were longer than those in control group (all P

Objective To discuss some problems about current learning objectives for the speciality of clinical medicine in China,including the concepts,the decision-making systems and value-orientation,and to provide the reference for stipulating the learning objectives in future. Methods The objectives of some Chinese medical universities were collected from their websites.Some medical educators were consulted about their feelings about these learning objectives,and also were asked to identify their own objectives. Results Medical educators failed to distinguish their own objectives,and there were four main problems in current learning objectives: generalization,similarity and lack of individuality,difficulty in guide the curricula and teaching,and setting up too high object. Conclusion The learning objectives in clinical medicine should reflect both specialty characteristic and university individuality,so they should be drawn up by teachers,students and educatirnal administrators,moreover their value orientation should be eligible standard,not excellence.

ObjectiveTo observe the curative effect of the Chinese traditional medicine combined with traction and physical therapeutic on lumbar intervertebral discprolapse (LIDP).Methods95 LIDP patients were randomly divided into the treatment group (50 cases) and control group (45 cases). Patients of the treatment group were treated by Chinese traditional medicine, traction and physical therapy. Patients of the control group were treated by traction and physical therapy only.ResultsThe total clinical effective rate of the treatment group was 100%, but that of the control group was 75.6%, there was a significant difference between two groups (P<0.05).ConclusionChinese traditional medicine therapeutics is an effective non-surgical therapeutics for LIDP.

Vitexin, a naturally occurring flavone glycoside in plants, has many pharmacological effects, which is widely distributed in nature. This paper reviewed the research progress of the distribution of vitexin in the plant resources and its pharmacological effects, and summarized its application prospects, aiming to provide a useful reference for the development of vitexin-enriched plant resources.

BACKGROUND: Basic fibroblast growth factor (bFGF) can accelerate the bone marrow mesenchymai stem cells (BMSCs) proliferation and differentiation into nerve cells, which is considered as a mitogen of glial cells.OBJECTIVE: To investigate the survival and differentiation of bFGF gene modified BMSCs transplanted on rat models of cerebral ischemia by double immunofluorescence staining, and to study the differentiation trend of BMSCs into neuron-like cells and glial cells.DESIGN, TIME AND SETTING: The randomized control animal experiment was completed in the central laboratory of Experimental Animal Center of Central South University from July 2005 to March 2006.MATERIAL: Fifty Sprague-Dawley rats were divided into 4 groups at random: sham operation group (n=10), cerebral ischemia-reperfusion injury group (n=10), BMSCs group (n=i5) and bFGF modified BMSCs group (n=15). METHODS: Except sham operation group, rats in the other three groups were prepared for local cerebral ischemia-reperfusion models. Then BMSCs or bFGF modified BMSCs were intravenously transplanted into cerebral ischemic rats, and the same volume of DMEM were injected in the cerebral ischemia-reperfusion injury group. MAIN OUTCOME MEASURES: Survival rate and differentiation of grafted cells were observed by 5-bromo-2-deoxyuridine (BrdU)-NeuN, and BrdU-glial fibrillary acidic protein (GFAP) double immunofluorescence staining; the neurological scores and infarction volumes in each group. RESULTS: At 7 days after implantation, the number of BrdU/NeuN-positive cells and BrdU-GFAP-positive cells in the bFGF modified BMSCs group was higher than those on the BMSCs group (P < 0.05), but there were no significant differences in the co-expression cells by double immunofluorescence staining between the two groups (P > 0.05). At 7 days following reperfusion, neural function of cerebral ischemia rats were improved and infarction volume was reduced in both BMSCs group and the bFGF modified BMSCs group, and bFGF modified BMSCs group was superior to BMSCs group. CONCLUSION: BMSCs modified by bFGF can survive in cerebral ischemic region and differentiate into neuron and glial cells, which are more proper for repairing nerves.

Thirty seven patients with congestive heart failure (CHF) were divided into cilazapril group (n=19) and general treatment group (n=18). Serum levels of interleukin-6 (IL-6) ,interleukin-8 (IL-8) , interleukin-10(IL-10) and tumor necrosis factor-α(TNF-α) , left ventricular ejection fraction (LVEF) ,left ventricular end-diastolic diameter (LVEDD), cardiac output (CO) and fractional shortening (FS) were measured before and after treatment. Serum levels of cytokines were also measured in 40 healthy individuals (control group). Results: The serum levels of IL-6, IL-8, IL-10 and TNF-α in CHF patients were significantly higher than those in the control group ( all P<0.01 ) ; After treatment, the serum IL-6, IL-8 and TNF-α were significantly decreased (P<0.01 ,P<0.05 ) in the cilazapril group. The LVEF, FS, CO were significantly increased in the Cilazapril group ( P<0.01 ) ; And the serum levels of IL-6 were significantly decreased in the cilazapril group as compared with the general treatment group ( P<0.05 ), however, after treatment, the EF, LVEF, FS and CO had no statistical differences in the cilazapril group as compared with the general treatment group. In the control group only LVEF and FS improved(P<0.01) ; Cytokine levels showed no changes. It suggests that cilazapril can reduce the serum levels of pro-inflammatory cytokines, increased the serum levels of anti-inflammatory cytokine, protect and improved cardiac function in the patients with congestive heart failure.

Objective To explore the therapeutic effect of electroencephalograph(EEG)biofeedback on clinical symptoms and cognitive function of children with attention deficit hyperactivity disorder(ADHD).Methods Twenty children aged(10.4?2.2)years old who were diagnosed as ADHD according to American Diagnostic and Statistical Manual of mental disorders the 4th ed received EEG biofeedback treatment.The treatment was administered by Autogenic A620 machine,? wave(4-8 Hz)was suppressed and sensory motor rate wave was strengthened(12-15 Hz)at the same time.The treatment was total 40 times.Before and after treatment,Conner's Behavior Rating Scale-parent questionnaire was administered to assess the clinical symptoms,wechsler memory scale(WMS)to assess the long-term memory,short-term memory and instantaneous memory,number cancellation test and stroop test were used to assess the cognitive process speed and selective attention,and continuous performance test(CPT)was administered to assess the attention and impulsiveness.The children in healthy control group who compared with ADHD children by one to one came from the primary or middle school near the hospital,the age difference between ADHD child and healthy control group was within 6 months.All the measurements were administered to the healthy control group.Results After the EEG biofeedback treatment,the score of behavior factor in Conners Scale decreased significantly(P0.05).Conclusions Forty sessions EEG biofeedback can improve clinical symptoms,attention,memory,selective attention and cognitive process speed of ADHD children significantly,some indicators even become normal.
