Objective To investigate the efficacy of low-dose retention enema for treating ulcerative colitis.Methods Eighty patients diagnosed with chronic recurrent ulcerative colitis were randomly divided into control group and observation group with equal number.The retention enema was used in the control group and the improved retention enema was used in the observation group. Enema was done once every night,10 days as a course of treatment in both groups.The two groups were compared in terms of liquid retention time,curative effect after two courses and patients’satisfaction degree with enema.Results The liquid retention time in the intestinal lumen in the observation group was significantly longer than that of the control group.The efficacy was significantly better than the control group.Patients satisfaction with enema in the observation group was significantly higher than that of the control group (P<0.05).Conclusions The improved low-dose liquid enema is effective in the treatment of ulcerative colitis for its liquid retention time in the intestines.It is effective,comfortable,convenient,and likely to be accepted by patients.

Up to now,there are 21 ministry of education innovation teams established by 37 independent medical colleges and universities,which has become an important part of the medical education system innovation team building.From the perspective of SWOT (strengths,weaknesses,opportunities,threats) analysis,in the process of ministry of education innovation team establishment in the independent medical colleges,there are unique advantages,followed by obvious disadvantages,and there are favorable outside opportunities,accompanied with unprecedented challenges.Independent medical colleges shall keep up with the development trend,leverage the national regional development policy,give full play to the advantages,endeavor to overcome weaknesses,seize the opportunities and face the challenges actively,make the right strategic decisions,in order to better play an irreplaceable role in higher medical education system.

By comparing the differences of " Decision of the Standing Committee of the National People's Congress on the prohibition against narcotic drugs " and "Law of the People's Republic of China on Narcotics Control " and their implications for harm reduction,the article analyzed the ethical issues existing in applying harm reduction policy in HIV/AIDS prevention and control,and held that the new policy to promote the methadone use would play a major role for control of drug abuse and AIDS.

The research capacity of a hospital has become an important criteria for hospital evaluation, Research activity and capacity in the hospital plays an important role in improvement of clinical care for patients.A tumor Hospital in Tianjin, has taken a full academic advantages and strengthen,providing strong support in research funding;standardizing the management on research outcome, and emphasize on translation of clinical research in recent years.We have explored the effective management model in scientific research activity.

AIM: To investigate the changes of myocardium glycogen content and the relation ship between changes of the myocardial glycogen content and the myocardial function. METHODS: Male Wistar rats were placed in (hypoxia rats) and made to swim in (hypoxia swimming rats) a hypobaxic chamber simulating an altitude of 5 000 m above sea level. The content of myocardium glycogens was determined by colorimetry. RESULTS: The myocardium glycogen content of rats significantly reduced along with the prolongation of hypoxic exposure and approached to control level in hypoxia swimming rats. The myocardial function of right ventricule was improved significantly compared with control group. CONCLUSION: Moderate exercise (Swimming) is beneficial to hypoxic adaptation of rats under the condition of chronic hypoxia.

Objective To propose new policies and strategies that will optimize the transformation of medical research achievements at hospital level.Methods In this paper,we systematically analyzed the characteristics and influencing factors of the transformation of medical research achievements based on the status quo in our hospital.Results In our hospital as an example,major problems in the transformation of medical research achievements identified as low investment,low conversion rate,complex procedures,multi-links existed and more multi disciplinary cooperation needed.Conclusions The hospital can take some measurements to optimize the transformation of medical research achievements,such as more stream lined management of scientific research project,establishing and improve the platform for scientific research transfer,increasing the funding,strengthening cooperation among different disciplinaries,building a professional team to promote the transfer and so on.

Objective To investigate the therapeutic effects and mechanism of Okam on asthmatic mice.Methods The mice model of asthma was established with the egg albumen sensitization, and were treated with low and large doses of Okam for four weeks.The pathological changes of lung tissues were observed.Immunohistochemistry was used to determine the contents of matrix metalloproteinases-9(MMP-9) and tissue inhibitor Metalloproteinase-1 (TIMP-1) in the lung tissues.Results Gasp and inflammation in the lung tissues were significantly relieved in the test groups than that in the model group.MMP-9,TIMP-1 and MMP- 9/TIMP-1 ratios were significantly lowered in the test group than that in the model group. Conclusion The marine drug of Okam shows therapeutic effects on mice with asthma,which may be the result of reduced contents of MMP-9 and TIMP-1 in the lung tissues and the correction of the imbalanced MMP-9/TIMP-1 ratio.Okam is likely to be a new choice for the treatment of asthma.

Objective: To observe the effect of tripterygium polyglycosid(TP,雷公藤) on airway inflammation and remodeling in rats with asthma.Methods: Forty rats were randomly divided evenly into negative control group,positive control group,normal dose TP group(TPⅠ group) and small dose TP group(TPⅡgroup).The experimental model was induced by ovalbumin sensitization.Number of cells in bronchoalveolar lavage fluid(BALF) was observed by immunocytochemical staining.The expressions of nuclear factor-?B(NF-?B),matrix metalloproteinases-9(MMP-9) and tissue of inhibitor of metalloproteinases-1(TIMP-1) were detected by immunohistochemistry method.Results: Compared with the negative control group,the counts of lymphocyte,neutrophilic leukocyte,macrophage and eosinocyte in BALF were elevated significantly,positive cell percentages of NF-?B, MMP-9 and TIMP-1 in lung tissues increased greatly in positive control group,the differences being significant(all P

The metabolism of thyroid hormone changes during pregnancy. Subclinical hypothyroidism during pregnancy may adversely affect the pregnancy outcomes and neuropsychological development of child, controversially. The diagnostic criteria of subclinical hypothyroidism during pregnancy need to be specific. It is important to figure out when should pregnancy with subclinical hypothyroidism be treated and what is the specific goal of the treatment.
