The present study deals with the histochemistry of intramural plexus in stomach, duodenum, ileum, caecum, proximal colon, distal colon and rectum of normal adult guinea pig, including the reaction of Mg~(++)-ATPase, Ca~(++)-ATPase, CCO, SDH, G6PDH, carbohydrate, protein, nucleic acid and lipid in the enteric neurons. The reactions of all the enzymes mentioned above are observed under the light microscope and estimated semiquantitatively, among which, Mg~(++)-ATPase and Ca~(++)-ATPase are measured quantitatively with microphotometer (Leitz MPV II). Both results of light microscope, and microphotometer were analysed statistically. It was found that the above mentioned enzyme activities in the enteric neurons, suggesting that the neurons carry out active metabolism with these concerned enzymes. There were significant differences in some enzyme activities between myenteric plexus and submucous plexus, the former showed higher activity in SDH, while the latter in LDH, G6PDH, and two kinds of ATPase. It is suggested that there are some differences in. the major metabolic manner of carbohydrate, energy metabolism and functional activity between, two plexus. Besides, there were marked difference in enzyme activities among myenteric plexus of different part of digestive tract, the highest activity was showed in duodenum and proximal colon, the lowest was in caecum. These results indicate that enteric neurons differ greatly in functional state, but whether or not the variation of enzyme activities is related with the different types of neurons is unknown.

There are Many gaps of medical psychology on course plans, teaching methods and examination methods in Chinese medicine institutions. Therefore, the teaching of medical psychology must be reformed. By improving course plans, strengthening multiple teaching methods and examination methods used, quality of teaching on medical psychology can be enhanced, and many persons with ability of traditional Chinese medical science can be educated to be abreast of bio-psycho-social medical model.

Objective:To establish a method for the content uniformity ( CU) of fennel oil in Weitongning tablets to study the CU of fennel oil in Weitongning tablets. Methods: Methyl salicylate as the internal reference, the content of trans-anethole in fennel oil was determined by GC. The separation was performed on a DB-FFAP capillary column (30 m × 0. 32 mm, 0. 25 μm) at 145℃, the injection part temperature was 180℃ and the FID detector temperature was 230℃, nitrogen with high purity was used as the carrier gas at the flow rate of 0. 8 ml·min-1 . The air flow rate was 400 ml·min-1 and that of hydrogen was 35 ml·min-1 . The methodology validation was carried out, and the samples from different companies with different batches were determined. Results:Significant differ-ence showed in the CU of fennel oil in the samples with different batches from the same manufacturer or from different companies. The trans-anethole showed linear correlation within the range of 2. 189-35. 030 μg · ml-1 ( r =0. 999 9 ) and the average recovery was 100. 06% (RSD=0. 5%, n=9). Conclusion:The method is simple and quick. It is accurate in the CU determination of fennel oil and can be used for the quality control of Weitongning tablets.

Objective To observe the anti-aging effect of Yinao capsule. Methods The rat model of acute incomplete cerebral ischemia was established, and determined the content of superoxide dismutase (SOD), lipid peroxidation (LPO) and Evans blue in brain tissue, determined the serum SOD content of normal rats. Formed blood platelet thrombus by common carotid artery-external jugular vein blood flow bypass operation of rats, and weighed wet weight of thrombus. Results The Yinao capsule can increase SOD and Evans blue content of brain tissue from rat model of acute incomplete cerebral ischemia, at the same time, decrease the LPO content. It can enhance serum SOD content of normal rats, and inhibit the formation of experimental thrombus. Conclusion The Yinao capsule can prevent the occurrence of senile diseases, and defer organism aging.

Objective To study the cardiac function effect of allopurinol for hypemricemia combined with dilated cardiomyopathy patients.Methods One hundred and twenty hypemricemia combined with dilated cardiomyopathy patients were divided into allopurinol group and control group according to the treatment method with 60 cases each.All the patients were given conventional treatment,the control group was added the nitroprusside treatment,and the allopurinol group was added the allopurinol and nitroprusside treatment.The treatment period was 3 months.Results The total effective rate in allopurinol group was significantly higher than that in control group [90.0％ (54/60) vs.75.0％ (45/60)],there was statistical difference (P ＜ 0.05).After treatment,the left ventricular ejection fraction and left ventricular posterior wall thickness at end-systole in allopurinol group were significantly higher than those in control group [(67.85 ± 7.12)％ vs.(30.78 ±7.00)％ and (1.40 ±0.20) mm vs.(1.16 ±0.18) mm[,but the left ventricular internal diameter at end-systole,left ventricular internal diameter at end-diastole and left ventricular posterior wall thickness at end-diastole were significantly lower than those in control group [(4.72 ± 0.41) mm vs.(6.48 ± 0.47) mm,(2.93 ± 0.32) mm vs.(5.56 ± 0.62) mm and (0.77 ± 0.13) mm vs.(0.92 ± 0.18) mm],there were statistical differences (P ＜ 0.05).After treatment,The uric acid,urea nitrogen and creatinine were significantly lower than those in control group [(45.43 ± 11.24) μ mol/L vs.(167.23 ± 19.22) μ mol/L,(10.23 ± 7.12)mmol/L vs.(40.93 ± 8.09)mmol/L and (32.01 ± 8.34) mmol/L vs.(78.09 ±9.11) mmol/L],there were statistical differences (P ＜ 0.05).Conclusion Allopurinol used for treating hyperuricemia combined with dilated cardiomyopathy patients can reduce uric acid,early reversal the atherosclerosis and improve heart function,it should be widely applied research.

Objective To examine the curative effect of EEG biofeedback therapy on children with attention deficit hyperactivity disorder (ADHD),and to investigate the neural mechanism underlying the executive function in children with ADHD.Methods 42 children with ADHD participated a Go/Nogo task before and after the EEG biofeedback therapy which was consisted of 20 times of treatments.The curative effect was evaluated using the behavioral and electrophysiological indexes associated with the Go/Nogo processing in the experiment.Results Commission error significantly decreased after the therapy ( (2.95 ±2.22 ) vs (4.65 ±4.47),P＜0.05 ).Latencies of P2 ( (210.00 ± 27.54) ms vs ( 228.27 ± 34.17 ) ms) and N2 components ( ( 310.59 ± 45.82) ms vs (328.00 ± 42.27)ms) elicited by Go trials significantly exhibited shorter at the end of therapy.Additionally,the amplitude of N2 component elicited by Nogo trials exhibited significantly decreased after therapy ((0.23 ±3.79)μV vs (-1.84 ± 4.23 ) μV,P ＜ 0.05).Conclusion The EEG biofeedback therapy is effective in debasing the hyperactivity/impulsive behaviors and improving the ability of target detection,which may be beneficial to the attention ability and conflict detecting in children with ADHD.EEG biofeedback is an effective treatment to ADHD.

Objective To investigate the relationship of microembolic signals (MESs) between the degree of symptomatic carotid artery stenosis, ultrasonic characteristics of plaques, peak systolic velocity at the stenotic site and risk factors for stroke. Methods A total of 52 patients with symptomatic carotid artery stenosis were enrolled. MESs of bilateral middle cerebral arteries were monitored and detected by carotid color Doppler flow imaging. Results The positive rate of MESs on the symptomatic sides was significantly higher than that on the asymptomatic sides (28. 8% vs. 4. 5%, P < 0. 05). The positive rate was not significantly correlated with the degree of stenosis, ultrasonic characteristics of plaques, peak systolic velocity on the stenotic sides, and risk factors for stroke. Conclusions MESs mainly occurred on the symptomatic sides of carotid artery stenosis, and they were more closely correlated with unstable plaques.
