Sinopodophyllum hexandruma is a traditional Chinese medicine in China,which is mostly distributed in Gansu,Shaanxi,Sichuan,Qinghai,Yunnan and Xizang,etc.In recent years,with the gradual deepening of the research on the chemical composition and pharmacology-toxicology of Sinopodophyllum hexandruma,its antitumour and antiviral pharmacodynamic evaluation has increasingly become a research hotspot in the industry.Based on the chemical structure,pharmacological properties and the theoretical basis of quality markers(Q-markers),this paper presents an in-depth literature review and analysis of the chemical composition,pharmacological activities and Q-markers of Sinopodophyllum hexandruma,and systematically explores and predicts the Q-markers of Sinopodophyllum hexandruma.It is proposed that Podophyllotoxin,picropodophyllotoxin,podophyllotoxinone,quercetin,kaempferol,quercetin-3-O-β-glucoside can be used as the Q-marker of Sinopodophyllum hexandruma.In the later stage,these index components can be selected to control the whole quality of Sinopodophyllum hexandrum,and provide some data support and theoretical reference for the quality evaluation of Sinopodophyllum hexandrum.

Brain renin-angiotensin system (RAS) is closely associated with many pathophysiological processes of cardiocerebrovascular diseases,including stroke.The activation of the different components in RAS will produce specific biological effects.This article reviews the roles of brain RAS in the pathophysiological processes of ischemic stroke,especially the neuroprotective effect of ACE2/Ang-(1-7)/Mas axis.

Objective: To evaluate recent prognosis of patients with acute ST elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI), and explore related risk factors.Methods: Clinical data of 168 STEMI patients undergoing primary PCI were retrospectively analyzed.According to occurrence of major adverse cardiovascular events (MACE) within 30d or not, they were divided into poor prognosis group (n=40) and good prognosis group (n=128).Clinical data were compared between two groups.Logistic regression analysis was used to analyze independent risk factors for MACE.Results: Incidence rate of MACE was 23.81% among the 168 STEMI patients.Logistic regression analysis indicated that age (OR=1.326, 95%CI 1.168~1.505), family history of coronary heart disease (OR=1.852, 95%CI 1.369~2.505), number of diseased vessels ≥2 (OR=1.682, 95%CI 1.382~2.047), Killip′s class Ⅲ~Ⅳ (OR=1.693, 95%CI 1.428~2.007) and onset-to-PCI time (OR=1.785, 95%CI 1.425~2.236) were the independent risk factors, P<0.01 all;TIMI grade 3 (OR=0.623, 95%CI 0.518~0.749) and tirofiban application (OR=0.452, 95%CI 0.367~0.557) were independent protective factors for MACE, P<0.01 both.Conclusion: Advanced aged, family history of coronary heart disease, number of diseased vessels ≥2, poor cardiac function and long onset-to-PCI time are independent risk factors, while TIMI grade 3 and tirofiban application are independent protective factors for MACE.

Objective To investigate and analyze the sleep disorder at different time points among commissioned and enlisted shipboard navy personnel during prolonged single ship deployment at sea.Methods The Pittsburgh Sleep Quality Index (PSQI) questionnaires were issued to 150 commissioned and enlisted navy personnel at month 1,2,3 and 4 during deployment at sea for self-evaluation of sleep quality of the shipboard navy personnel.Results One hundred and two commissioned and enlisted navy personnel completed the questionnaire survey.The PSQI scores in the first,second,third and fourth months were 4.09 ± 2.23,5.87 ± 2.09,7.26 ± 3.32 and 7.71 ± 3.87 respectively.Statistical significance could be noted in the scores,when comparisons were made between months (P ＜ 0.01).With the scores ＞ 7 as the critical point of sleep disorder,the percentages of the people with sleep disorder at 4 different time points were respectively 29.4％ in the first month,34.3％ in the second month,47.1％ in the third month and 48.0％ in the fourth month,and statistical significance could be noted,when comparisons were made between groups (P ＜ 0.01).Statistical differences could be noticed in sleep quality,sleep latency,sleep efficiency and daytime dysfiunction,when comparisons were made between the months (P ＜ 0.01).There was no obvious correlation between PSQI scores and the age,educational background,position (officers or soldiers) and years of service (P ＞ 0.05).Conclusions During this prolonged single ship deployment at sea,the rate of sleep disorder occurred among navy personnel was relatively higher.With the extension of deployment at sea,sleep latency was prolonged,sleep efficiency and sleep quality were decreased and daytime dysfunction deteriorated.

OBJECTIVE: To prepare thermosensitive meloxicam hydrogel and establish its quality control method.METHODS: The hydrogel was prepared with poloxamer 407 and poloxamer 188 as base.The content of meloxicam in the thermosensitive gel was determined by UV spectrophotometry.RESULTS: The thermosensitive meloxicam hydrogel was yellowish or flavovirens in color,with its identification and tests all in conformity with the related specification stated in Chinese Pharmacopeia(2005 edition).The linear response range of meloxican was 1.956～19.56 mg?L-1(r=0.999 7).The average recovery was 98.42%(RSD=1.53%).CONCLUSION: The preparative technique is simple,and the quality of the preparation is controllable.

0 05). In 53 ITP patients, the positive rate of PAIgG was 64 2% (34/53), the positive rate of mean fluorescence intensity (MFI) was 71 7% (38/53), the positive rate of both PAIgG and MFI was 84 9% (45/53). The expression of GPⅡb/Ⅲa in ITP group without clinical symptoms was significantly higher than that in ITP group with clinical symptoms ( P

This paper is to study the clinical characteristics of Brugada syndrome (BrS) in Chinese by analyzing clinical and ECG data of BrS patients. Data were included by computerized and manual research, and was analyzed by 2 doctors alone. The data of repetition and of non-Chinese were rejected. Forty-nine BrS patients were included (45 males and 4 females). Main manifestations included sudden death in 29 and syncope in 27 patients. Malignant ventricular arrhythmia (MVA) occurred in 14 of 17 patients with family history of sudden death or syncope and in 15 out of 32 ones without family history. Occurrence of MVA in 11 of 14 patients was within the period from 7pm to 7am. ECG revealed that sloped ST segment elevation appeared mainly in V1, V2 leads and coved ST segment elevation appeared mainly in V3 lead. BrS is not rare in Chinese people,and its clinical characteristics is similar to that overseas data.

Objective To investigate the function and clinical significance of platelet-derived microparticles (PMP), glycoprotein(GP)Ⅱb-Ⅲa, PagT and blood-lipid in whole blood of patients with cerebro-thrombotic diseases before and after treatment. Methods The quantity of PMPs, activation ratio of GPⅡb-Ⅲa and PAgT were measured before and after treatment of cerebro-thrombotic patients by using flow cytometry and platelet adhesion instrument. Blood-lipid concentration was measured by automatic-biochemical analyzer. Results PMP, GPⅡb-Ⅲa , PAgT, TC, TG, and LDL were (223?54)/10 4 Plt, (77.98?14.22)%, (69.78?16.93) %, (5.12?0.85) mmol/L, (1.78?0.28) mmol/L, and (3.49?0.66) mmol/L respectively before treatment; and were (136?18)10 4Plt, (40.71?11.64) %, (58.12?12.51)%, (4.84?0.73) mmol/L, (1.43?0.33) mmol/L, and (3.03?0.62) mmol/L,respectively in the treatment group. These parameters were significantly decreased than that before treatment (P
