Objective: To establish a quantitative method for determination of protocatechuic acid in Xueniao Capsules. Methods: The capsules were extracted with alcohol acetic acid (10∶1) and then solved with absolute alcohol. The sample was applied on a silica H plate, developed and separated in the solution of chloroform acetone methanol acetic acid (7∶2∶1.5∶0.5). The separated spots were determined by TLC scanning at 530nm(? s). Results: The average recovery was 101.4%. Conclusion: This method for determination of protocatechuic acid in Xueniao Capsules was sensitive, accurate and specific. It could be used as quality control for Xueniao Capsules.

The hypo-morality,also known as sub-morality,is an imperfect morality compared with the social mainstream morality.By introducing some "hypo-morality" phenomena in the current physician-patient relationship and analyzing from the two aspects including the diversity of interests main bodies and the market operational mode of healthcare institutions,this paper assures the rationality of the existence of hypo-morality in physician-patient relationship,and attempts to provide feasible suggestions for a reasonable direction of hypo-morality in physician-patient relationship.

For 10 years recently,China has implemented the strategy of "rejuvenating technology,talents for the first",and China's higher education has made improvement significantly: the number of student in-class increases drastically,the gross enrollment rate of higher education reached the level of popular education.Kunming Medical College,in this particular historical period of development by accelerating the construction and structural adjustment, strengthening management,taping potential,integrating use of resources,has better dealt with the enormous pressure and the challenge caused by the school's operating scale's nearly five times increase,and has ensured the quality of student training;In the new historical period of development, Kunming Medical College will continuously change education ideas,achieve the leap development from teaching university to teaching and research university positively.

The contrast of technical force between hospital and society is astonishing in the maintenance & service of large-scale medical equipment.When the maintenance & service plan must be chosen to socialized service,all the plans must be seriously compared and evaluated according to the current situation of the equipments in hospital for an economical and suitable selection.A right selection is necessary in promoting maintenance and management of large-scale medical equipment,keeping good operation of equipment,prolonging service life,and creating better economic and social benefits.

Objective:To investigate the clinical efficacy ofacupuncture plus Tuina therapy in treating supraspinatus tendinitis.Methods:One hundred patients with supraspinatus tendinitis were randomly allocated to two groups.The treatment group of 50 cases was treated with acupuncture plus Tuina therapy and the control group of 50 cases,with simple acupuncture.Treatment was given once daily,10 times as a course.The therapeutic effects were evaluated after two courses oftreatment.Results:The total efficacy rate was 96.0%in the treatment group and 74.0%in the control group.x2 test showed that there was a statistically significant difference in the total efficacy rate between the two groups(P＜0.01).Conclusion:Acupuncture plus Tuina therapy is superior to simple acupuncture in treating supraspinatus tendinitis.

Intracanal antisepsis acts as one of the fundamental steps in root canal therapy. Intracanal medication is very common among the multitudinous root canal disinfection methods so far. However, as the most frequently-used intracanal medication, calcium hydroxide exists some problems, such as insufficient antimicrobial power and antibiogram. Thus exploring new root canal disinfectant is necessary. Herbal medicine is gaining favor for its wide varieties, broad efficacy and affordable prices. The current researches revealed that many kinds of herbs or compound herbal preparations possess good ability of antimicrobial and other properties that superior to those of traditional root canal disinfectants. However, herbal medicine itself and the studies have shortcomings. This paper will provide a review of various herbal alternatives that are being studied of late years.

OBJECTIVE：To study the secretion of catecholamine primary cultures of chromaffin cells from rat adrenal medulla were used.METHOD:Catechoalmines(norepinephrine,epinephrine and dopamine) were measured by high-performance liquid chromatography-electrochemical detection technique.RESULTS:Catecholamine released by chromaffin cells with in 20min without slimalus was (73.29±15.32) ng/106 cells.When acetylcholine,nicotine or muscarine was added,the secretion of catecholamine was then increased.CONCLUSION:Using high-performance liquid chromatography-electrochemical detection technique,we can detect sensitively catecholamine released by cultured rat chromaffin cells.

Objective To investigate the effect of Sufentainil on myocardial ischemia-reperfusion injury and caspase-3 to rat heart. Methods Ninety Wistar rats weighing 200-300g were randomly divided into 3 groups(n=30):sham group(group S), ischemia-reperfusion group (group I/R)and Sufentainil group (group SF). Each group was divided into 3 subgroups according to the time phases at 30, 60 and 120min(n=10).In group I/R and group S the animals were received normal saline intravenously. In group SF sufentainil 5μg/kg NS 20ml was given. After 24 h, all animals were anesthetized with intraperitioneal 20% urethane 1 mg/kg, intubated and mechanically ventilated. The chest was opened and heart exposed via thoracotomy.In group S , left artery anterior descending artery(LAD) was not ocluded. While in I/R and SF group myocardial ischemia was introduced by clamping LAD for40 min. The animals were killed at 30, 60 and 120 min of reperfusion respectively(n=10each). Cardiac tropoin I(cTnI), expression of caspase-3 and apoptosis of cell in heart tissues were measured at the same time.Ultrastructure of myocardium taking the from apex was examined by electron microscopy at the end of 120 min reperfusion. Results Compared with group S, the concentration of cTnI was increased in the other 2 groups(P<0.05).cTnI was significantly lower in group SF than in group I/R(P<0.05). Expression of caspase-3 and apoptosis index induced by myocardial reperfusion were attenuatated in group SF(P<0.05). The damage of myocardial ultrastructure caused by myocardial I/R were also significantly improved in group SF. Conclusion Sufentainil may relieve the heart cellular apoptosis by decreasing caspase-3expressing.
