Motor cortex electrical stimulation was first used in the clinical treatment of central pain in 1989.Recently,this technique has been used to treat post-stroke movement disorders and better efficacy has also been obtained.Its mechanisms may include regulating cortex-basal ganglia circuits,exciting the activation of the motor cortex on the affected side but inhibiting the activation of the motor cortex on the contralateral side.regulating the plasticity of brain and resynchronization of electric activity.This article reviews the possible mechanisms,operative methods.clinical efficacy and existing problems.

The toxic Chinese materia medicia (CMM) has been considered as the combination of active ingredients and toxic ingredients. After reviewing on the theory of traditional Chinese medicine (TCM),combined with clinical and experimental researches,it was found that the two kinds of ingredients have dialectical relationship,they were manifested with "double-side" or "multi-surface" ,even could change into each other. Based on the above understanding,the new research mehods were proposed as follows:Evaluating toxicity of toxic CMM under the physiological and pathological states; Establishing its drug-nature and toxicity under the different pathological states; Focusing on different pathological states to establish the best combination of active and toxic ingredients; Exploring the transitional mechanism of the active and toxic ingredients.

[Methods] To retrospectively analysis 36 cases who were confirm diagnosed.Their clinical feature, endoscope feature, pathologic types and curative effect of therapy were analyzed. [Rusult]Most carcinoma site located at anterior or posterior wall at lesser curvature of mid-upper part of gastric body. Endoscope feature: mucosa plica were tumefactional, small node formated, erosion, it was easy to bleeding. Biopsy: Mojority carcinoma type was BorrmannⅡ and Ⅱb and Ⅱc type. More topical biopsy and deep biopsy were necessary for improving biopsy positive rate. [Conclusion] Endoscope and biopsy are effective methods for early diagnosis of gastric signet-ring carcinima.

Objective To evaluate the changes of growth hormone(GH), brain natriuretic peptide(BNP) and adrenomedullin(ADM) in congestive heart failure patients. Methods The blood samples were obtained from 60 pa-tients with congestive heart failure(CHF) and 30 patients without CHF,and their serum/plasma levels of GH,BNP and ADM were measured by enzyme-labeled immunosorbentassay(ELISA) and radioimmunoassay. At the same time all the patients received colorful Doppler ultrasonocardio-gram to determine left ventricular end-dilation diameter (LVED) and left ventrieular ejection fraction(LVEF). Results The levels of BNP and GH in heart failure group were[(0.83±1.06) μg/L,(115.31±191.16) ng/L] higher than eontrol group[(0.15±0.42) μg/L, (33.51±49.85) ng/L] (t = 2.689, t = 2.765, P < 0.01); The efficiency and total efficiency in heart failure group was (39.7% ,76.5%) higher than control group (32.3%, 61.3%) (t = 1.894, P > 0.05, t = 2.265, P < 0.05); The sensitivities and specificities of BNP were 89.3% and 63.0%; The sensitivities and specificities of GH were 85.7% and 59.3%; The BNP combined with GH were 75.0% and 74.0%. Condusion The combination of GH and BNP is better than application alone in the diagnosis of CHF.

Methods The allergic dermatitis patients were rardanly selected as observation group and normal person or non-suffering allergic dermatitis as control group. The maximus thenar dermatoglyphic patterns of palm were classified into three grades on the basis of its tend towards, distance, depth and character of cleavage lines, and the degree of moistening, dryness, softness, smoothness of surface skin, etc. Results There are 82 examples in observation group, grade Ⅰ is 11 examples, degree Ⅰ of grade Ⅱ is 17 examples, degree Ⅱ of grade Ⅱ is 31 examples, grade Ⅲ is 23 examples. There are 86 examples in control group, grade Ⅰ is 71 examples, degree Ⅰ of grade Ⅱ is 5 examples, degree Ⅱ of grade Ⅱ is 6 examples, grade Ⅲ is 4 examples. There is significant difference between the observation group and control group (P

Objective To explore the effect of formaldehyde on learning and memory and the activity of superoxide dismutase (SOD) in the cerebral tissues. Methods 40 ICR mice were randomly divided into four gropes: A-control group (NS was added into water bottle), B, C, D-three formaldehyde dose groups (0.1, 0.2, 0.4% formaldehyde solution were added into water bottles). After 30 days of treatment, the ability of learning and memory were evaluated by Morris watermaze test and step-down test and the activity of SOD in the cerebral tissues was determined. Results In the Morris watermaze test (the fifth day), escapelaten latence in group C[ (29.23?5.56)s] and D[ (37.36?7.39)s] were significantly longer than group A[ (21.65?5.81)s](P

OBJECTIVE:To study the stability of Yinzhihuang injection(YZH) mixed with 5% glucose solution,10% glucose solution,glucose in normal saline,normal saline and Ringer's solution.METHODS:After YZH mixed with infusion fluid under room temperature,the contents of baicalin were determined with UV-spectrophotometry at different time periods within 24h,the apperance was observed,the pH values of baicalin were detected and identified by TLC.RESULTS:Under room temperature,after YZH mixed with Ringer's solution,the pH value of baicalin was markedly changed and a lot of white particles appeared;after YZH mixed with GNS,no changes of pH value and content of baicalin were found within 24h.When YZH mixed with other 3 kinds of infusion fluid,there were no changes in pH value and content of baicalin within 2h,however,in mixing with NS,the number of insoluble particles produced was beyond the standard.CONCLUSION:YZH should not be mixed with NS or Ringer's solution but it is compatible with 5%GS,10%GS and GNS,however,it should be mixed with them just before use and used up within 2h.

BACKGROUND:Fracture healing is the coupling interaction of osteoblasts and osteoclasts that promotes bone growth, in which osteoblast-mediated bone resorption and osteoclasts-mediated bone reconstruction make the bone reconstruction in a dynamic equilibrium to promote bone growth. However, the majorities of the current studies focus on osteogenic or osteoclastic mechanism alone, and ignore the interaction mechanism between these two cels under co-existing conditions.
OBJECTIVE:To investigate the effects of Kidney Chinese Herbs on osteoblasts and osteoclasts coupling of osteoprotegerin-receptor activator of nuclear factor kappaB ligand-receptor activator of nuclear factor kappaB and its mechanism of action in fracture treatment.
METHODS: Mouse osteoblasts and osteoclasts were isolated and cultured in vitro to establish the mouse “osteoblast-osteoclast co-culture system” as a research platform. Then, Kidney Chinese Herbs at doses of 1.25, 2.5, 6.25 g/(kg?d) were given intragastricaly for 7 consecutive days. Mice in the blank control group were fed with the same volume of normal saline.
RESULTS AND CONCLUSION:The alkaline phosphatase activity in osteoblasts co-cultured with osteoclasts was significantly higher than that in osteoblasts cultured alone at 24 hours of culture (P < 0.05). Real-time PCR showed that in the co-culture system, the expression of alkaline phosphatase, Runt related transcription factor 2 and osteoprotegerin were increased in a dose-dependent manner (P < 0.05). Western blot assay showed 6.25 g/(kg?d) Kidney Chinese Herbs could dramaticaly promote the expression of osteoprotegerin and receptor activator of nuclear factor kappaB ligand, but restrained the expression of receptor activator of nuclear factor kappaB (P < 0.05). These findings indicate that Kidney Chinese Herbs can dynamicaly regulate the osteoprotegerin-receptor activator of nuclear factor kappaB ligand-receptor activator signaling pathway, and has a positive effect to promote bone reconstruction and rehabilitation.

Objective To investigate the efficacy of foramen magnum decompression alone and foramen magnum decompression + Syrinx-shunt in the treatment of Chiari anomalies with syringomyelia.Methods Forty-nine Chiari anomalies with syringomyelia patients were selected,28 patients performed foramen magnum decompression alone (surgical method Ⅰ group),21 patients performed foramen magnum decompression + Syrinx-shunt (surgical method Ⅱ group).The treatment efficacy was evaluated by postoperative clinical effect and MRI review.Results In surgical method Ⅰ group,effective in 18 cases,invalid in 10 cases,the effective rate was 64.3％ (18/28).In surgical method Ⅱ group,effective in 19 cases,invalid in 2 cases,the effective rate was 90.5％(19/21).There was statistical difference (x2 =4.45,P =0.034).Conclusion Foramen magnum decompression + Syrinx-shunt is effective in the treatment of Chiari anomalies with syringomyelia,which is applicable for these patients and has a more precise consequence than foramen magnum decompression alone.
