Objective To observe the effect of acupuncture plus early-stage rehabilitation training on the neurological function and levels of serum ischemia-modified albumin (IMA) and neuron-specific enolase (NSE) in patients with acute cerebral infarction.Method Sixty-eight patients with acute cerebral infarction were randomized into a treatment group and a control group, 34 cases each. The control group was intervened by conventional medications, while the treatment group was intervened by acupuncture plus early-stage rehabilitation training in addition to the medications given to the control group. The two groups were both treated once a day, 10 d as a treatment course. Three treatment courses later, the changes of serum IMA and NSE levels were observed; the Modified Edinburgh-Scandinavian Stroke Scale (MESSS), Barthel Index (BI) and Fugl-Meyer Assessment (FMA) scores were compared before and after the treatment.Result The MESSS, BI and FMA scores were significantly changed in both groups after the intervention (P<0.01). After the intervention, the MESSS, BI and FMA scores in the treatment group were significantly different from those in the control group (P<0.05). The serum IMA and NSE levels were significantly changed in both groups after the intervention (P<0.01). After the treatment, the serum IMA and NSE levels in the treatment group were markedly lower than those in the control group (P<0.01).Conclusion Acupuncture medication combined plus early-stage rehabilitation training can promote the recovery of neurological function of acute cerebral infarction patients, which is related to the down-regulation of serum NSE and IMA levels.

Objective To compare the analgesic efficacy and side effects of patient-controlled intravenous analgesia (PCIA) with Lornoxicam and patient-controlled epidural analgesia(PCEA) with morphine in patients undergoing Orthopaedics surgery. Methods 100 ASA Ⅰ-Ⅱ Patients scheduled for Orthopaedic surgery were divided randomly into two groups: Lornoxicam PCIA group( n =50) , Lornoxicam 48mg was diluted to 100ml with normal saline (0.9%NS).

There was no significant difference in side effects between the two groups except the occurrence of sweat, nausea, vomiting and skin pruritus which was lower in group PCIA than in group PCEA ( P

Objective To sum up the experience of position nursing of patients with ankylosing spondylitis and severe kyphosis. Methods Eleven patients with ankylosing spondylitis and severe kyphosis underwent surgery. The patients′spine and head were kept in a line during anesthesia to avoid spinal cord injury. The eye mask was used to make sure the eyelid close, so the bulbar conjunctiva and corneal did become dry. The angle of operation bed in time during operation was adjusted. The crushed area was observed and the position was changed to avoid pressure sores and edema. After surgery, they were keep inactive to make sure the spine stable and relieve the pressure. Results The 11 patients′surgery were successful. There were no pressure ulcer, fracture, spinal cord injury or eye injury occurs. The operation time was 9.3 ± 2.9 h. Conclusion Position nursing is very important to improve the success rate of surgery and reduce complications.

The neurovascular unit (NVU) consists of neurons,gllal cells and microvessels,etc.There were complex interactions among the various cellular components,which form as a uniform entirety preferably.Anong the various cellular components of NVU,the signal transduction occurred disorders during cerebral ischemia,resulting in neuronal and extracellular ratrix destruction,and thus occurring cerebral infarction and hemorrhagic transformation.Therefore,the treatment of ischemic sttroke should be based on the protection of the overall function of NVU.This article describes the changes and protection of NVU after cerebral ischemia.

Objective To evaluate the long-term efficacy and safety of donepezil in treating patients with Alzheimer's disease(AD).Methods Totally 86 patients with AD were randomly divided into control group(n =43)and treatment group(n =43).The control grou,p received conventional therapy with aniracetam,nimoldipine and ginkgo tablet,while the study group was administrated with donepezil(10 mg/d)on the basis of conventional therapy.The improvements of recognitive ability,mental state,activities of daily life were graded by mini-mental state examination (MMSE),Alzheimer's disease assessment scale-cog(ADAS-cog),activity of daily living(ADL)and global deterioration scale(GDS).The scores were compared between the groups before the treatment and 3,6,12,18,24,30,36,42,48,54,60,66 and 72 months after the treatment,respectively.Results The scores of MMSE,ADAS-cog and GDS after 3 months and ADL score after 6 months (t=2.361,-2.198,-1.790,-2.420,P＜0.05 or P＜0.01)were improved in treatment group than in control group with the best effects at 12 months(all P＜0.01)and the scores continued to decrease after 36 months.At 72 months,the score improvements in treatment group were 7.5 for MMSE,20.3 for ADAS-cog,19.5 for ADL,and 1.4 for GDS as compared with control group(all P ＜0.01).In contrast to pretreatment,there were statistically significant differences in the scores of MMSE,ADAS-cog and GDS at 3,6,12,18 and 24 months,and in the score of ADL at 6,12,18,24 and 30 months after treatment(P＜0.05 or P＜0.01).The differences in the scores of ADAS-cog and GDS after 24 months as well as MMSE and ADL after 30 months were not found(P＞0.05)between pre-treatment and post-treatment.Conclusions Donepezil might be long term effective and safe in slowing down the recognitive and overall function deterioration of AD.

BACKGROUND:Hyperbaric oxygen(HBO)treatment promotes the proliferation and differentiation of endogenous neural stem cells in neonatal rats following hypoxic/ischemic brain damage(HIBD).The Wnt signaling pathway is associated with neurogenesis.However,there are few data recording the role of HBO in the differentiation of neural stem cells in vitro.OBJECTIVE:To observe the effect of HBO on differentiation and Wnt3 expression of bone marrow mesenchymal stem cells(BMSCs).METHODS:BMSCs were isoiated and cultured.The rat BMSCs of passages 3-5 were cultured in DMEM/F12(1:1)medium with basic fibroblast growth factor,epidermal growth factor and B27 for 24 hours.The induced BMSCs were randomly divided into two groups:control group(no treatment)and HBO group(HBO,0.10 MPa,60 minutes stabilizing pressure with at least 90% oxygen).The neuron specific encloase(NSE),glial fibrillary acidic protein(GFAP)and 04 marked oligodendrocyte immunocytochemistry were detected by immunofluorescent staining,and Wnt3 protein expression was detected by Western-blot.RESULTS AND CONCLUSION:BMSCs cultured in classic medium of neural stem cells could significantly induce the expression of nestin.The expression of NSE and 04 of HBO group was greater than control group(P＜0.01),but GFAP expression displayed no significant difference between the groups(P＞0.05).Western blot showed HBO could enhance the Writ3 expression (P＜0.05).Results show that HBO can induce BMSCs to differentiate into neural cells and oligodendrocyte,which is correlated with the activation of the Wnt3 protein.

Objective To investigate the effects of remffentanil pretreatment on myocardial ischemiareperfusion (I/R) injury in rabbits. Methods Thirty healthy rabbits, aged 12-18 months, weighing 2.5-3.5 kg,were randomly divided into 3 groups (n = 10 each): I/R group, low-dose remifentanil pretreatment group (group R1 ) and high-dose remifentanil pretreatment group (group R2 ). Myocardial I/R was induced by ligation of anterior descending branch of left coronary artery for 30 min followed by 6 h of reperfusion in the 3 groups. Remifentanil was infused intavenously at 1.65 and 3.30 μg· kg - 1 · min- 1 for 30 min before ischemia in group R1 and R2 respectively, while equal volume of normal saline was infused instead in group I/R. Blood samples were taken for determination of serum cardiac troponin-Ⅰ (cTnI) and creatine kinase-MB isoenzyme (CK-MB) concentrations before administration (baseline), after administration, at 30 min of ischemia and at 6 h of reperfusion. The rabbits were then sacrificed and hearts removed. Myocardial tissues were obtained for microscopic examination. Results Serum cTnI and CK-MB concentrations were significantly lower in group R1 and R2 than in group I/R and serum cTnI concentration lower in group R2 than in group R1 ( P ＜ 0.01). Remifentanil infusion significantly attenuated the pathologic changes in a dose-dependent manner. Conclusion Remifentanil pretreatment provides protective effect against myocardial I/R injury in rabbits and it is related to the dose.

AIM: To explore the influence of different concentration midazolam on the macroscopic voltage gated potassium currents and to discuss the relationship between potassium currents and inhibitory effect of clinical relevant concentration midazolam on sympathetic nervous system. METHODS: Superior sympathetic ganglion neurons were dissociated enzymatically from 7 to10 day old rat. Experiments were performed about 5 h after plating at room temperature (20- 24 ℃ ). Appropriate solution was chosen to separate the K + current from the other transmembrane currents. 1 ?mol?L -1 TTX was applied to the extracelluar solution to block the Na + current. Midazolam was also resolved in extracelluar solution to get various concentration ( 0.1 , 0.3 ,3,10,50,100 ?mol?L -1 ). Currents were recorded with the patch clamp technique in whole cell configuration using glass electrodes with a tip resistance of 2- 4 M . Potassium currents were evoked by test pulse from -100 mV to +30 mV with holding potential -80mV. Data were analyzed using Clampfit 6.0 and Oringih 5.0 software. Whole cell current records were corrected for leakage and capacitance by using the P/5 protocol. RESULTS: Midazolam dose dependently inhibited the whole cell potassium currents. Clinical relevant concentration midazolam ( 0.3 ?mol?L -1 ) only reduced the peak currents by 3.89 %(P= 0.88 ). The concentration required to produce 50% current inhibition(IC 50 ) was 76.065 ?mol?L -1 . CONCLUSION: Midazolam inhibits the whole cell potassium current significantly and dose dependently, but clinical relevant concentration midazolam has minor effect on the potassium currents, indicating that the inhibitory effect of midazolam on potassium current is not related to the suppression of activity of sympathetic system.
