Upper gastrointestinal hemorrhage (UGH) is a kind of intensive disease commonly encountered clinically. In recent years, the diagnosis and treatment method of UGH had achieved satisfied progress. But with the development of aged tendency of population, its morbidity is still in a high level. Especially in older patients with serious complications, the fatality rate is much higher. It has been proved practically, traditional Chinese medicine (TCM) has remarkable effects in treating UGH. This article summarized the progress of TCM or integrative medicine studies on UGH through etiology and pathogenesis, therapeutic principle and methods.

Objective To investigate the impact of acupoint massage on the vital signs of patients with angina pectoris in coronary artery heart disease (CHD) during the operation. Methods Using non-concurrent cohort controlled design, 38 cases who with angina pectoris in CHD received interventional therapy, from June to September in 2015, in the therapy rooms of our hospital were selected as control group and received routine nursing. 38 cases who with angina pectoris in CHD received interventional therapy, from October 2015 to January 2016, in the therapy rooms of our hospital were selected as intervention group and received acupoint massage based on routine nursing. Heart rate and blood pressure of patients in two groups were monitored and recorded during the operation. Results Compared with control group, systolic blood pressure of patients in intervention group decreased obviously (143.26±17.67 vs. 153.18 ± 19.35) mmHg (1mmHg=0.133 kPa), diastolic blood pressure decreased obviously (83.16 ± 12.29 vs. 93.82 ± 16.54), and heart rate decreased obviously (71.89 ± 13.90 vs. 79.05 ± 12.63) mmHg (t=2.33, 3.19, 2.35, P<0.05 or 0.01). Conclusions Acupoint massage can effectively reduce heart rate and blood pressure of patients with angina pectoris in CHD during the operation, relieve patients' anxiety, and help for smoothing operation, shortening operation time and reducing operation risk.

Objective To investigate the retention level and its influencing factors for male nurses,and explore effective strategies to increase retention level of male nurses.Methods A sample of 610 male nurses from many hospitals in Tianjin were investigated with the self-designed demographic questionnaire,Retention Scale and Perceived Organization Support.The results underwent analysis.Results Male nurses' retention score was (20.71±4.00) points.Single factor analysis found that marriage,age,number of children,time engaged in nursing work,the working years in present position,the purpose of the work had statistically significant influence on retention scores of the male nurses.Multiple linear regression analysis showed that marriage,professional and technical titles,the purpose of work,work support and value identification were the predictive effect on the degree of the retention.Conclusions The retention of male nurses in Tianjin was in the medium level.Hospitals and all relevant departments should take effective measures,improve the professional sense of worth of the male nurses and job satisfaction,in order to enhance the man nurses' retention rate,promote the sustainable development of the nursing team construction.

Aim To study the distributive character of mitomycin(MMC) magnetic nanoparticles and MMC normal saline solution in mice.Methods A HPLC method for the determination of MMC in tissues and serum were established and applied to determine MMC in biological samples.Results Under the guidance of an external magnetic field,targeting rates of MMC to liver viscus are 82.72% after 30 minutes tail vein administration of(1 mg?kg~(-1)) mitomycin magnetic nanoparticles,it was 2.37 times larger than targeting rates of MMC normal saline solution group.The distributions of heart and kidney of mitomycin magnetic nanoparticles were less than that of MMC normal saline solution group.Compared with the results of tail vein administration mitomycin nanoparticles,interaction between the external magnetic field and magnetic nanoparticles is significantly effective to increase targeting rates of MMC to liver.Compared with the results of tail vein administration mitomycin magnetic nanoparticles without the external magnetic field,Mitomycin magnetic nanoparticles under the guidance of an external magnetic field is significantly effective to increase targeting rates of MMC to liver.Conclusions Mitomycin magnetic nanoparticles under the guidance of an external magnetic field is significantly effective to increase targeting rates of MMC to liver and prolonging effect on the action in vivo.

OBJECTIVETo compare the protein profiles between decapeptide-treated and untreated planktonic cells of Streptococcus mutans (S. mutans) by differential proteomic analysis to determine and identify the key proteins.

METHODSIn our previous study, we investigated decapeptide (KKVVFKVKFK-NH2), which was a novel adenosine monophosphate. Compared with other oral pathogens tested, decapeptide had a preferential antibacterial activity against S. mutans. It also inhibited S. mutans biofilm formation and reduced the one-day developed biofilm. In the present study, we first synthesized decapeptide, and then compared the protein profiles between decapeptide-treated and untreated planktonic cells of S. mutans by two-dimensional gel electrophoresis and matrix-assisted laser desorption ionization time-of-flight mass spectrometry. We also verified different expressions of key protein enolase in the protein level.

RESULTSThe results showed that decapeptide altered the protein expression of planktonic S. mutans. These proteins were functionally involved in carbohydrate degradation by glycolysis, protein folding, conjunction, transport, translation, adenosine triphosphate binding, protein binding, sequence-specific DNA binding, transcription factor activity, and two-component response regulator activity. Western blot results showed that enolase protein expression decreased obviously in decapeptide-treated cells of S. mutans.

CONCLUSIONThe protein expression of S. mutans significantly changed after synthetic antimicrobial decapeptide treatment, suggesting that decapeptide may present a preferential effect on oral caries by changing the expression of certain key proteins, such as enolase protein.
