Natural product seselin and related derivatives with an angular pyranocoumarin skeleton were synthesized from 8-acetyl-7-hydroxycoumarins by condensation with acetone, reduction, and dehydration successively under mild conditions with total yield of > 50%. Twelve seselin derivatives were tested by the writhing response assay induced by acetic acid at a dose of 40 mg x kg(-1). Seselin (4a) and 4,8,8-trimethyl-9,9-dihydro-pyran[2,3-f] chromene-2,10-dione (2b) showed obviously antinociceptive activity with inhibitory effect of 85% and 50%, respectively, more or quite potent than aspirin in the same assay, suggesting that seselin derivatives could be a novel kind of potential antinociceptive agents.

OBJECTIVETo investigate the impact of 5-aza-2'-deoxycytidine(5-aza-CdR) combined with imatinib on the proliferation, motility, invasion, and apoptosis of gastrointestinal stromal tumors(GIST) cells in vitro.
METHODSMTT assay was used to investigate the effect of the two agents on proliferation of GIST882. Plate colony forming assay was used to determine the number of colony-forming. Motility and invasion abilities were tested to evaluate the inhibitory effect of each agent. Flow cytometry was used to observe apoptosis and cell cycle.
RESULTS5-aza-CdR or imatinib effectively inhibited the growth of GIST882 cells in concentration- and time-dependent manner. The inhibitory rate of combined treatment using 5-aza-CdR and imatinib was significantly higher than that of 5-aza-CdR or imatinib alone(P<0.05). After treatment for 48 h, the apoptosis rates of 5-aza-CdR group (1000 μg/L) and imatinib group (100 μmol/L) were (11.7±1.2)% and (14.6±0.8)%, respectively. Compared with the control group (2.8±0.3)%, the difference was statistically significant(P=0.000). Furthermore, the difference in apoptosis rate was significant between combined treatment group (19.4±1.1)% and single drug treatment group(vs. 5-aza-CdR group, P=0.000, vs. imatinib group, P=0.013). 5-aza-CdR raised G0/G1 ratio and reduced S ratio of GIST882. Imatinib and combined group had no apparent influence on the cell cycle of GIST882 cells.
CONCLUSION5-aza-CdR may be a potential agent of GIST treatment in the near future.

OBJECTIVEBased on the 2002 WHO health survey data, to explore the latent relationship among self-reported health level, the actual level of health, the social demographic characteristics and the risk factors, and to analyze the influence of the various surveillance indicators on self-reported health and the degree that the self-reported health explained the actual level of health.
METHODSField tests for various components of the World health survey were conducted in nine countries during 2002, including India, Brazil, Burkina, Hungary, Nepal, Russia, Spain, Tunisia, and Vietnam (29 971). The survey questionnaire included a self-assessment component and anchoring vignette component. The self-assessment component data was adjusted and eliminated the affect of "cut-point bias" by using the anchoring vignette component data, and then was used to build the structural equation model on the relationship among self-reported health level, actual health level, social demographic characteristics and the risk factors.
RESULTSIn the final structural equation model, "the actual level of health" = 0.80 × "the self-reported health level" + (-0.04) × "the social demographic characteristics" + (-0.08) × "the risk factors" (R(2) = 0.66), and "the self-reported health level" = (-0.70) × "the social demographic characteristics" + 0.10 × "the risk factors" (R(2) = 0.55). The standardized total effect of self-reported health to the actual level of health was 0.80, and that of the social demographic characteristics to the self-reported health and the actual level of health were -0.70 and -0.60, respectively. And the 16 items of self-reported health consisted of 8 dimensions; and sorted by the power of impact to the actual health level, they were mobility, pain and discomfort, sleep, cognition, feelings, self-care ability, visual capacity and interpersonal activities.
CONCLUSIONThere were significant linear correlation relationship between the actual level of health and the self-reported health, as well as between the self-reported health and the social demographic characteristics. And the self-reported 16 items used by the 2002 WHO health survey played an important role in the health evaluation of population.

OBJECTIVETo study the newborn's Apgar score in 'one minute' and relevant factors.
METHODSOne year inpatient woman from a Maternal and Child Health Hospital of Anhui province were selected by cluster sampling method and newborn asphyxia situation was investigated using Apgar score and self-designed questionnaire.
RESULTSThe Apgar score in 'one minute' which marking 8 to 10, 4 to 7 and 0 to 3 were found in 1875 (73.78%), 426 (16.77%) and 240 infants (9.45%) respectively. The average Apgar score in 'one minute' and five minutes were (7.69 +/- 2.27) and (9.01 +/- 1.89) respectively, The Apgar score in 'one minute' was significantly correlated with that of five minutes (Pearson coefficient correlation r = 0.841, P = 0.00). Ordinal regression analysis revealed that parturient age (OR = 1.04), being farmer (OR = 2.22), parity (OR = 1.26), assistant vaginal delivery (OR = 4.93), caesarean section (OR = 1.95), pregnancy-induced hypertension syndrome (OR = 1.42), albuminuria in gestational period (OR = 1.44), newborn being male (OR = 1.23), low birth weight (OR = 2.94), inborn abnormality (OR = 12.12), premature birth (OR = 1.22) and complications of delivery (OR = 5.04) were risk factors while the number of years under study (OR = 0.91), prenatal check-up (OR = 0.48), body length of newborn infant (OR = 0.88) and single birth (OR = 0.57) were protective factors.
CONCLUSIONApgar score in 'one minute' of newborn infant was affected by several factors as stated above. Health care program in earlier period toward community parturient should be strengthened in order to discover and control high risk factors of duration of pregnancy in earlier period.

Shengxiantang, one of the classical traditional Chinese medicine (TCM) prescriptions, was developed by ZHANG Xi-chun, a well-known doctor in the Republic of China, to treat the syndrome of pectoral Qi sinking. Due to the unique herbal composition, this prescription has yielded remarkable outcomes, and it is still widely used for dealing with diseases of various systems. This paper reviewed the clinical research concerning Shengxiantang in order to provide reference for its clinical application. Following the retrieval of related articles published in the past ten years from China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, Chongqing Weipu Database for Chinese Technical Periodicals (VIP), and Chinese Biomedical Literature Service System (SinoMed) with the Chinese key words of “Shengxiantang (升陷汤)”, “sinking of pectoral Qi (大气下陷)”, “replenishing Qi and raising the sinking (益气升陷)”, and“pectoral Qi theory (大气理论)”, this paper collated the clinical application experience of Shengxiantang. To be specific, the corresponding etiology and pathogenesis, interpretations of Shengxiantang, as well as its indications, application experience and precautions were summarized to provide a basis for its further research and application. Based on the collected more than 50 representative articles, it was found that Shengxiantang has been extensively utilized for treating complex and critical diseases of various systems, especially the circulatory and respiratory diseases and organ prolapse. The research on the clinical application of Shengxiantang has deepened, exhibiting a promising development trend, which will provide new ideas for its clinical application.
