Objective T_O analyze the electrophysiological features of shoulder-hand syndrome(SHS)fol- lowing stroke and investigate the relationships between peripheral nerve damage and the factors causing SHS.Meth- ods Fifty-eight stroke patients were divided into an SHS group(39 patients with shoulder-hand syndrome)and a model group(19 patients without shoulder-hand syndrome).Standard sensory and motor nerve conduction studies were performed with 58 of the patients,including sensory nerve conduction velocity(SCV),amplitude of the sensory nerve action potential(SNAP),distal motor latency(DMI)and the amplitude of the compound muscle action poten- tial(CMAP)of the median nerve.A needle electromyogram(EMG)test was performed on the abductor pollicis of the affected side with both groups.Results The needle EMG showed abnormal insertion potential,fibrillation po- tential and positive sharp waves in all 39 cases of the SHS group,which was significantly higher than in the model group.The amplitude of the sensory nerve action potential(7.77?4.34 mV)and the amplitude of the compound muscle action potential(10.13?3.15 mV)were significantly lower than those of the model group.Abnormal ampli- tude was more severe in sensory nerves than in motor nerves.Conclusion Peripheral nerve damage was found in the shoulder-hand syndrome patients,and this damage was mainly the dystrophy of axonal neuropathy.The damage severity was more in sensory nerves than in motor nerves.The study could offer an useful clue of prevention and treat- ment of shoulder-hand syndrome.

OBJECTIVE:To evaluate the cost and effectiveness of two chemotherapy regimens in the treatment of initially di-agnosed multiple myeloma (MM). METHODS:63 patients who were newly diagnosed as MM without transplant chance in our hospital were analyzed retrospectively,and then divided into MPT group (alkeran+metacortandracin+thalidomide,41 cases) and VDT group (bortezomib +dexamethasone+thalidomide,22 cases) according to chemotherapy regimens. Clinical efficacy,survival time and ADR of 2 groups were observed,and cost-effectiveness analysis of them were conducted. RESULTS:The overall re-sponse rates of MPT group and VDT group were 63.4% and 77.3%,respectively(P=0.260);the complete response rate of them were 12.2% and 36.4%,with statistical difference(P=0.024). The progression free survival of MPT group and VDT group were (14.314±0.488)months and(18.557±0.848)months,with statistical significance(P<0.001);the overall survival of MPT group and VDT group were(33.536±1.143)months and(41.048±1.868)months,with statistical significance(P=0.007). Leukocytope-nia,nausea and vomit and peripheral neurotoxicity of VDT group were both higher than those of MPT group,with statistical signif-icance (P<0.05). The cost-effectiveness ratio of MPT group was 247.48,and that of VDT group was 2 922.77;the incremental cost-effectiveness ratio was 15 125.18. The results were consistent with the sensitivity test. CONCLUSIONS:Clinical efficacy and survival time of VDT regimen is better than that of MPT regimen,but MPT regimen is superior to VDT regimen in respect of cost-effectiveness analysis and the incidence of ADR. which will more suitable for the MM patients without transplant chance or goood economic conditions.

Objective To use peer education to guide community diabetic patients to adopt diet therapy using food exchange method in order to explore effective method for diet therapy of diabetes mellitus. Meth-ods 91 diabetic patients were selected using simple sampling method and randomly divided into the peer ed-ucation(45 cases) and the common education group(46 cases), the two groups adopted food exchange method for diet therapy for 1 year. The blood glucose, blood lipid, glycosylated hemoglobin and body weight index were compared between the two groups using t test. Results The blood glucose, blood lipid, glycosylated hemoglobin and body weight index all decreased in the two groups after intervention, but the the decreased de-gree in the peer education group was more obvious. The fasting blood glucose, 2 hour postprandial blood glu-cose, glycosylated hemoglobin, triglyceride, low-donordensity lipid protein and body weight index in the peer education were lower thanthose of the common education group, but HDL-C was higher. Conclusions Peer education is more effective in health education of food exchange method.

OBJECTIVEThe changes of pain threshold and expression of 5-hydroxytryptamine(5-HT) and c-Fos in spinal dorsal horn of rats were observed after targetedly damaged the cerebraspinal fluid-contacting nucleus (CSF-contacting nucleus) to provide experimental evidence for the mechanism of regulating pain CSF-contacting nucleus involved in.

METHODSMale adult SD rats were divided into control, sham, choleratoxin subunit B conjugated with horse-radish peroxidase (CB-HRP)and damage groups randomly. The pain threshold using mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were recorded and analyzed. Immunofluorescence method was used to observe the expression of 5-HT and c-Fos in spinal dorsal horn.

RESULTSCompared with the control, sham and CB-HRP groups, the MWT and TWL of the damage group were significantly increased (P < 0.05). The results of immunofluorescence showed that 5-HT was detected in neurons of CSF-contacting nucleus. In the damage group, the number of neurons of CSF-contacting nucleus reduced gradually, and no survived neurons were observed at the 10th day. Meanwhile, both the expression of 5-HT and c-Fos in spinal dorsal horn increased gradually, and negatively correlated with the change of pain threshold.

CONCLUSIONThe method of targeted damaging CSF-contacting nucleus by cholera toxin subnit B conjugated with saporin(CB-SAP) is scientific and reliable, and it results in the changes of pain threshold and expression of 5-HT and c-Fos in spinal dorsal horn of rats. This study suggests that CSF-contacting nucleus participate in the regulation of pain, moreover, 5-HT and c-Fos play important roles in this regulation.
