AIM:To investigate the effects of tanshinone IIA ( Tan) on cardiac action potential in rats with a-cute cerebral ischemia (ACI).METHODS:ACI was established in rats accordingly .Animals were divided into 3 groups:sham group, ACI group, and ACI with Tan treatment group .The defect of neural function in each group was graded , elec-trocardiogram was measured , monophasic action potential was recorded , and the levels of cardiac troponin I ( cTnI ) and creatine kinase-MB ( CK-MB) were examined by commercially available kits .RESULTS:Compared with ACI group , Tan significantly decreased the scores of the defect of neural function , reduced the incidence and duration of the abnormalities in electrocardiogram , prolonged the effective refractory period , action potential duration at 50%repolarization and action po-tential duration at 90%repolarization, and inhibited the elevation of cTnI and CK-MB levels.CONCLUSION:Tan main-tains a stable heart rhythm in ACI rats , which may be related to its protective effect on ischemic myocardium .

ObjectiveTo investigate the outcomes of mother a nd baby smaller than 37 gestational age caused by preeclampsia. Method sThe data for 122 preterm birth that was single pregnancy with preecla mpsia in our hospital from January 1993 to December 2002 were collected. The pri nciple of diagnosis and treatment, the outcomes were analyzed retrospectively. T he 122 pregnant women were divided into 3 groups according to their gestational age, more than 28 weeks and smaller than 31 +6 weeks was the first group (28 cases), more than 32 weeks and smaller than 33 +6 weeks was the second grou p (26 cases), more than 34 weeks and smaller than 36 +6 weeks was the thir d group (68 cases). The data were statisted with SAS software.Results The earlier the pregnancy-induced hypertension happened, the earlier the preeclampsia occured, the mean time was 14 03 d, 16 85 d,22 22 d, respect ively, (P0.05), the outcomes of mothers were good. Increasing the gestational age under the cond ition that the occurrene of comptications was not increased, 60 64% pregnant wo men accepted the treatment of improving the maturity of fetal lung. There were n o differences among the three groups at the morbidity of perinatal SGA, intracra nial hemorrhage (P 0.05) .ConclusionWe could improve the outcomes of pret erm birth caused by preeclampsia by enhancing the perinatal care, treating and t erminating pregnancy activey Increasing the gestational age, improving the matur ity of fetal lung would decrease the morbidity of severe RDS and improve the pe rinatal outcome effectively.

ObjectiveTo discuss the features and laws of online learning of graduate studnets in Beijing University of Chinese Medicine (BUCM); To provide references for the directions of guidance and improvement. Methods Graduate students from the grade 2014 in BUCM were set as the investigation objects. Questionnaire was used to investigate students’ online learning experience, learning channels, time frequency, main contents for online learning, learning achievements and shortcomings, and cognitive degree of MOOCs. Students were invited to write down their understanding of online learning and their opinions and suggestions for the new learning mode of combining MOOCs and classroom learning.Results In this survey, 92.16% of graduate students had the experience in online learning; 41.18% of the students did online learning through the campus network; 47.06% of students kept“once a week” frequency of online learning; 54.90% of students learnt through the network mainly used to develop extracurricular knowledge; 66.27% of students thought online learning had a certain learning harvest; 49.41% of students thought complicated network information brought certain problems. In the MOOCs cognitive survey, 43.92% of students did not understand MOOCs completely; 66.27% of students wanted to try MOOCs as a new study mode; 30.98% of students thought the hours of MOOCs should accounts for a quarter of the total class hours.Conclusion Most graduate students have experience in online learning, have certain learning achievements and have expectations for MOOCs teaching.

Discovery of noncoding RNA(ncRNA)over the past decade has reflected a paradigm shift of traditional RNA research. There is evidence that RNA can function not only as a messenger between DNA and protein,but as a regulator of genome organization and gene expression,which is increasingly elaborate in complex organisms. ncRNA seems to operate at many levels,however,in?cluding the physiological and pathological status. The research of ncRNA in pharmacology has not been summarized before. Here,we reviewed the emergence of the ncRNA in the research of pharma? cology,such as acting as biomarkers and medical targets. Besides,we mentioned their role in drug resistance and drug addiction in order to highlight the significant role of ncRNA in pharmacology.

Objective; To evaluate the reliability and reasonability of maxillofacial skin color match using the digital camera. Methods; The stability of the experimental light source was evaluated before establishing the color measurement. 122 volunteers aged from 22 to 32 years were recorded by a Canon EOS 20D digital camera in studio environment when the light source was stable. Photographs were taken under a set exposure parameters(f/4.5,1/25 s,custom white balance,ISO 800) and saved as JPEG format. The CIE L~* a~* b~* color values were obtained from the digital images using Adobe Photoshop7.0 after color correction. All data were analyzed using SPSS 10. 0. Results;The experimental light source was stable in 21 to 70 minutes. It was suitable for color measurement during this period. The color parameters of all tested maxillofacial skin were:L~*49～66,a~*7 - 18,b~*5 -22. Conclusion;The assessment of maxillofacial skin color depend on method of measurement and instrument. The method of maxillofacial skin color matching by digital camera seems reliable.

Changes of free amino acids in plasma and brain of rats with fulminanthepatic failure were measured with a Beckman 6300 amino acid analyzer.Results indicat-ed that as hepatic encephalopathy developed, concentrations of almost all amino acids inplasma and brain were increased.The levels of most amino acids in brain showed no cor-relation with their changes in the plasma.However,changes of concentrations of theseamino acids in brain that were related to the development of hepatic encephalopathy wereclosely correlated with their concentrations in plasma.Not any correlations between chan-ges of any amino acids in plasma and brain were found in normal control rats.Theseresults suggested that amino acid transport mechanisms appeared to be specific in the blo-cd-brain barrier during fulminant hepatic failure,a phenomenon that could contribute tothe neural disturbance of hepatic encephalopathy.

Focal adhesion kinase( FAK) ,a cytoplasmic non-receptor protein tyrosine kinase,serves as both a molecular scaffold and a mediator participating in multiple signal transduction pathways.FAK is involved in tumor cell survival,proliferation,migration and metastasis.Recent studies have shown that FAK is expressed in many tumor cells.Currently,FAK has been regarded as a potential target for cancer therapy.This review is to summarize the relationship between FAK and tumor progression.

OBJECTIVE:To explore the method of pharmaceutical care which influence the effect of the treatment for diabetes mellitus at home. METHODS:163 patients with diabetes mellitus in community who received treatment at home were selected, and then randomly divided into control group (58 cases),family visit group (51 cases) and group education group (54 cases);control group were given pharmaceutical intervention with traditional dispensing window;family visit group received door-to-door service or telephone follow-up service;group education group were given collective education and interactive way. The latter two groups were all given regular drug education,and the advisory desk was set up and provided consulting services about medication knowledge. RESULTS:After providing pharmaceutical care,the regular medication rate of 3 groups were 43.1%,64.8% and 78.4%;medication adherence were 51.7%,70.4% and 82.4%;the rates of blood glucose at target level were 29.3%,48.1% and 54.9%;the rates of glycosylated hemoglobin at target level were 13.7%,31.5% and 31.4%,ADR occurance rates were 31.0%, 13.0%,5.9%. These index of family visit group and group education group were all better than those of control group significantly (P<0.05). CONCLUSIONS:Humane pharmaceutical care can improve the quality and effect of the treatment for diabetes mellitus.

Pancreatic cancer is one of the deadliest cancers of the digestive tract with an obviously increasing incidence around the word in recent years.It is diffcults to diagnosis in the early stage because of the deficience of specific symptoms.Radical resection is the most effective method to treat pancreatic cancer,but those patient often lose radical surgery opportunity when be diagnosised at advanced stages.Their prognosis is poor.Early diagnosis can greatly improve the rates of radical resection and promote the prognosis of the disease,and reliable tumor markers can be used for early screening and early diagnosis for pancreatic cancer.In recent years,the rapidly development of proteomics and its technology makes tumor markers become a popular research fields in pancreatic cancer.

The co-existence of physician-patient disharmony and the high rate of cesarean section suggest that there must be some internal relationship between the two medical phenomena.The physician-patient disharmony not only increases the rate of non-indicative cesarean section,but also leads to artificial expansion of the cesarean section indicators.Building up a harmonious physician-patient relationship is an important safeguard to reduce the rate of cesarean section and protect the benefits of mothers and infants.
