Objective To study the chemical constituents from the roots of Euphorbia sonngarica. Methods Compounds were isolated by Sephadex LH-20,MPLC,and silica gel column chromatographies. Their structures were identified by spectral methods together with physicochemical analysis.Results Eleven compounds were isolated from the roots of E.sonngarica.They were identified as cryptomeridiol (Ⅰ),betulin(Ⅱ),betulinic acid(Ⅲ),3?-hydroxy-olean-12-en-28-oic acid(Ⅳ),7-oxo-?sitosterol (Ⅴ),erythrinasinate(Ⅵ),octaeosanoie acid(Ⅶ),1-octacosene(Ⅷ),24-methene-cycloartenol(Ⅸ),eu- phol(Ⅹ),?-sitosterol(Ⅺ).Conclusion CompoundsⅠ-Ⅷare isolated from this plant for the first time.

Membrane proteins are the main undertakers of biofilm function, and also the most important target group for innovative drug discovery and research. About 60% of drugs targets are membrane proteins. Due to the obvious aggregation and denaturation tendency of membrane proteins in aqueous solution, it is difficult to simulate the membrane like environment to maintain the correct conformation of membrane proteins in vitro, which results in the slower-growing research on the structure and function of membrane proteins and related ligand drugs than that of water-soluble proteins. Membrane protein stabilization technology is the premise of establishing high specificity, high sensitivity and high throughput drug screening methods for membrane protein ligands, which is of great significance. In this paper, some techniques for stable separation and purification of membrane proteins are reviewed, including detergents, artificial membranes, polymers, lentiviral particles and so on, as well as their specific applications in drug screening.

Objective Application of the second metatarpophalangeal joint by traction prolong trans- plant repair the defects in the metacarpophalangeal joint,reconstruct the function of it.Methods By means of the apparatus to prolong finger in advance,then transplant the second metatarpophalangeal joint to recon- struct metacarpophalangeal joint for seven cases of obsolete defects in the metacarpophalangeal joint.Results The average of finger prolong was 2.6 cm,consultation from 1 to 4 years.average 2.5 years,thai the trans- plant joints have all survived and osteal concrescence.Through the criterion Chinese Medical Association,good rate was 85.7%. Conclusion It' s a good method to repair obsolete defects in the metacarpophalangeal joint by transplant traction prolong of the second metatarpophalangeal joint.

Objective To investigate the effects and relations of carvedilol on heart rate turbulence and secretion of sympathetic nerve in patients with myocardial infarction. Methods Sixty-six patients selected with acute myocardial infarction were randomized to enroll into experimental group ( n = 33 ) treated with earvedilol and control group( n = 33 ) treated with metoprolol for 12 months follow-up treatment. The concenrrarions of plasma norepinephrine(NE) and epinephrine (E) and 24 hour Holter monitoring were messured respectively before the treatment ,after 6 months and 12 months; and new cardiac events were supervised for all cases. Quantification of heart rate turbulenee(HRT) were carried out by computer analyzing two factors: turbulence onset(TO) and turbulence slope(TS) from the data of 24 hour Holter monitoring. NE,E,TO,TS and the occurrence rate of new cardiac events were compared between two groups and in different times of treatment. The correlation between TO,TS and NE,E was analysed. Results Before the treatment, there was no significant differences between two groups to the comparisons of NE,E,TO and TS(P＞0.05). After treating 6 and 12 months, NE, E and TO of experimental group were all lower than control group's significantly, accordingly TS were all higher(P＜0.05). By comparing 3 times( before,after 6 and 12 months of treatment), NE, E and TO of two groups dropped, meanwhile TS rose; experimental group showed significant changes( P＜0.05 ), but control group showed no significant differences(P＞0.05 ). The occurrence rate of new cardiac events of experimental group was lower than control group's significantly (P＜0.05 ).There was significant correlation between NE, E and TO, TS (P＜0.05 ). Conclusion Carvedilol treatment can block the secretion of sympathetic nerve after myocardial infarction and prevent the occurrences of new cardiac events significantly; the changes of the secretion of sympathetic nerve can play an important role for heart rate turbulence (HRT) ,the changes of HRT would be hopeful to predict new cardiac events alter myocardial infarction.

OBJECTIVETo observe the changes of mental stress life events (MSLE) in patients with cyclomastopathy of liver stagnation syndrome type (LSS).

METHODSClinical epidemiological research method was adopted, the changes of MSLE were observed in cyclomastopathy patients of LSS or non-LSS, classified by syndrome differentiation of TCM.

RESULTSNot only the mean age (33.38 +/- 6.76 years) of patients with LSS was obviously lower than that of patients with non-LSS (38.36 +/- 9.89 years, P < 0.01), but also the mean age of patients with moderate and serious symptoms of LSS (33.96 +/- 7.31 and 37.43 +/- 7.38 years) were higher than that of patients with mild symptoms of LSS (31.67 +/- 5.39 years, P < 0.05 and P < 0.01). MSLE score of patients with LSS (32 scores) was significantly higher than that of patients with non-LSS (22 scores, P < 0.01). MSLE score of patients with moderate and serious LSS was 34.69 +/- 17.78 scores and 51.65 +/- 20.75 scores respectively, both were significantly higher than that of patients with mild LSS (26.57 +/- 15.85 scores, P < 0.05 and P < 0.01).

CONCLUSIONThe high incidence age of cyclomastopathy is under 40 years, and most of cyclomastopathy patients are classsified to LSS by TCM syndrome differentiation. So age and life event scores may be the objective bases for syndrome typing and liver stagnation syndrome grading in patients with cyclomastopathy.
