Objective To provide a scientific basis for early clinical diagnosis and treatment as well as secondary and tertiary protection through 10 years inquiry of multiple organ failure in the elderly(MOFE).Results Among 153 MOFE cases,the first inducement of 89.5%(137/153) patients was infection,among which 93.4% (128/137) was pulmonary infection.The vertical percentage of the first failure organ was as follows: pulmonary (39.0%,60/154),heart (19.5%,30/154),brain (14.9%,23/154),kidney (10.4%,16/154),alimentary canal (8.4%,13/154),liver (6.5%,10/154);while the horizontal percentage was as follows: pulmonary (42.9%,60/140),heart (40.9%,56/137),kidney (32.6%,30/92),brain (21.9%,23/105),alimentary canal ( 14.5%,9/62).The survival time of the first organ failure from shortness to length was as follows: pulmonary,brain,heart,kidney.Conclusions Most MOFE cases have pulmonary failure at first.The organs failure sequence is pulmonary,heart,brain and kidney in order.

Objective To approach the changes of cytosol phospholipase A2α(cPLA2α)and nitric oxide (NO)in patients with chronic obstructive pulmonary disease(COPD)and its significance. Methods One hundred patients with COPD admitted into Department of Critical Care Medicine of Affiliated Wuqing Traditional Chinese Medicine(TCM)Hospital of Tianjin University of TCM were enrolled,and according to the COPD severity grading standards,they were divided into mild group(25 cases),moderate group(25 cases),severe group(26 cases) and extremely severe group(24 cases);simultaneously,90 cases with normal pulmonary function who had taken health examination were chosen and assigned to the healthy control group. The cPLA2α level was detected by enzyme linked immunosorbent assay(ELISA),the level of uric acid(UA),total cholesterol(TC),triacylglycerol (TG)were detected by enzymatic method,and serum NO metabolites(NOx)level was detected by nitrate reductase method. Results Compared with the healthy control group,the serum levels of cPLA2α and UA in patients with different severity of COPD were significantly increased;along with the increase of patient's COPD grade of severity,the cPLA2α,UA levels were gradually increased,while NOx level was gradually decreased in mild, moderate, severe, extremely severe groups〔cPLA2α(ng/L):125.60±8.17, 155.20±6.42, 190.20±9.32, 255.80±11.28 vs. 88.50±7.99;UA(μmol/L):381.23±32.22,434.95±87.71,464.81±52.65,487.45±82.61 vs. 241.95±52.33;NOx(μmol/L):59.90±17.52,45.60±6.17,38.20±4.08,25.70±3.04 vs. 74.90±18.31,all P<0.05〕. The differences in blood cPLA2αand serum NOx level among groups with different severity of COPD were of statistical significance(P<0.05). The levels of TC,TG among these different severity groups had no statistical significance(all P>0.05). The cPLA2αand NOx levels presented significant negative correlation(rs=-0.798,P=0.013). Conclusion The combined examination of blood cPLA2αand serum NOx levels can evaluate the severity degree of COPD patients,and cPLA2αcan be used as a new target index for COPD grading.

OBJECTIVETo investigate the chemical constituents of Ehretia thyrsiflora.

METHODCompounds were isolated with silica gel, Sephadex LH-20 and RP-C18 colum chromatography. Their structures were elucidated by means of physico-chemical properties and spectral analysis.

RESULTSix compounds were isolated and identified as beta-sitosterol (1), ethyl caffeate (2), 2-methoxyl benzoic acid octyl ester (3), tetradecenoic acid, 2,3-dihydroxypropyl ester (4), daucoster (5), allantoin (6).

CONCLUSIONCompounds 1-5 were obtained from this species for the first time. Compounds 2-5 were obtained from the genus Ehretia for the first time.
