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.

Objective: To evaluate the efficacy and safety of a domestic human plasma derived coagulation Factor Ⅸ concentrate (pd-FⅨ) in patients with hemophilia B. Methods: The study was a multicenter, open-label and single-arm study. The efficacy of pd-F Ⅸ was evaluated by objective performance criteria. The doses of pd-FⅨ were calculated according to the bleeding symptom and disease severity. The infusion efficiency of pd-FⅨ and improvement of bleeding symptoms were measured at 30 minutes and (24±4) h after the first infusion, respectively. Adverse events were recorded. Viral infection and FⅨ inhibitor were detected 90 d after the first infusion. Results: All 36 subjects with hemophilia B were enrolled in the study. The median age of these patients was 31 years old and the median injection doses were 4 (1-17) times. The hemostatic effect of 27/36 (75.00%) and 9/36 (25.00%) acute bleeding events were rated as "excellent" and "better" , respectively. The recovery rate was 111.92% (65.55%-194.28%) at 30 minutes after infusion of FⅨ. There was no adverse event related to FⅨ. No reactivation of HBV, HCV or HIV and FⅨ inhibitor was detected at 90-104 d after the first FⅨ infusion. Conclusion: This domestically made human plasma derived FⅨ concentrate is safe and effective in the treatment of acute bleeding in patients with hemophilia B. Clinical trial registration: China food and Durg Administration, 2016L08027.

Objective: To evaluate clinical characteristics and prognosis of primary myelofibrosis (PMF) patients with thrombocytopenia in varied degrees. Methods: Clinical features and survival data of 1 305 Chinese patients with PMF were retrospectively analyzed. The prognostic value of thrombocytopenia in patients with PMF was evaluated. Results: 320 subjects (47%) presented severe thrombocytopenia (PLT<50×10(9)/L), 198 ones (15.2%) mild thrombocytopenia [PLT (50-99)×10(9)/L] and 787 ones (60.3%) without thrombocytopenia (PLT ≥ 100×10(9)/L). The more severe the thrombocytopenia, the higher the proportions of HGB<100 g/L, WBC<4×10(9)/L, circulating blasts ≥ 3%, abnormal karyotype and unfavourable cytogenetics (P<0.001, P<0.001, P=0.004, P<0.001 and P<0.001, respectively) were observed in this cohort of patients. The more severe the thrombocytopenia, the lower the proportion of JAK2V617F positive (P<0.001) was also noticed. Platelet count was positively correlated with splenomegaly, HGB and WBC (P<0.001, correlation coefficients were 0.131, 0.445 and 0.156, respectively). Platelet count was negative correlated with constitutional symptoms and circulating blasts (P=0.009, P=0.045, respectively; correlation coefficients were -0.096 and -0.056, respectively). The median survival of patients with severe thrombocytopenia, mild thrombocytopenia and without thrombocytopenia were 32, 67 and 89 months, respectively (P<0.001). Multivariate analysis identified thrombocytopenia in varied degrees (HR=1.693, 95%CI 1.320-2.173, P<0.001) and Dynamic Internation Prognostic Scoring System(DIPSS) prognostic model (HR=2.051, 95%CI 1.511-2.784, P<0.001) as independent risk factors for survival. Conclusion: PMF patients with severe thrombocytopenia frequently displayed anemia, leucopenia, circulating blasts and short survival, so active treatment measures should be taken especially in these patients.

Objective: To explore the clinical implications and prognostic value of TP53 gene mutation and deletion in patients with myelodysplastic syndromes (MDS) . Methods: 112-gene targeted sequencing and interphase fluorescence in situ hybridization (FISH) were used to detect TP53 mutation and deletion in 584 patients with newly diagnosed primary MDS who were admitted from October 2009 to December 2017. The association of TP53 mutation and deletion with several clinical features and their prognostic significance were analyzed. Results: Alterations in TP53 were found in 42 (7.2%) cases. Of these, 31 (5.3%) cases showed TP53 mutation only, 8 (1.4%) cases in TP53 deletion only, 3 (0.5%) cases harboring both mutation and deletion. A total of 37 mutations were detected in 34 patients, most of them (94.6%) were located in the DNA binding domain (exon5-8) , the remaining 2 were located in exon 10 and splice site respectively. Patients with TP53 alterations harbored significantly more mutations than whom without alterations (z=-2.418, P=0.016) . The median age of patients with TP53 alterations was higher than their counterparts[60 (21-78) years old vs 52 (14-83) years old, z=-2.188, P=0.029]. TP53 alterations correlated with complex karyotype and International prognostic scoring system intermediate-2/high significantly (P<0.001) . Median overall survival of patients with TP53 alterations was shorter than the others[13 (95%CI 7.57-18.43) months vs not reached, χ(2)=12.342, P<0.001], while the significance was lost during complex karyotype adjusted analysis in multivariable model. Conclusion: TP53 mutation was more common than deletion in MDS patients. The majority of mutations were located in the DNA binding domain. TP53 alterations were strongly associated with complex karyotype and always coexisted with other gene mutations. TP53 alteration was no longer an independent prognostic factor when complex karyotype were occurred in MDS.

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.
