Objective To investigate the risk factors of upper gastrointestinal injury induced by non-steroidal anti-inflammatory drugs (NSAIDs).Methods A total of 1032 patients which used NSAIDs was selected.Patients were divided into two groups based on the condition of dyspepsia,peptic ulcer or upper gastrointestinal bleeding:the adverse drug reaction group (331 cases) and the control group (701 cases).Data of two groups on clinical presentation,laboratory test,medication and treatment were analyzed.Risk factors for the adverse drug reaction were identified by multivariable Logistic regression.Results The two groups had significant difference in age ＞ 65 years old,Helicobacter pylori (Hp) infection,ulcer history,drug overdose,combination with glucocorticoid,addicted to tobacco and alcohol history,non-specific inhibitor of cyclooxygenase(COX)-2,combination with anticoagulant,concomitant chronic cardiopulmonary disease (P ＜ 0.05).Logistic regression analysis by backward elimination method revealed that following variables retained,such as combination with glucocorticoid (OR =3.104,95％ CI 1.936-4.695),Hp infection (OR =2.768,95％ CI 2.047-3.742),drug overdose (OR =2.411,95％ CI 1.683-3.453),ulcer history (OR =1.781,95％ CI 1.278-2.480),age ＞ 65 years old (OR =1.659,95％ CI 1.237-2.225),non-specific inhibitor of COX-2 (OR =1.470,95％ CI 1.103-2.133),addicted to tobacco and alcohol history (OR =1.459,95％ CI 1.032-2.064),concomitant chronic cardiopulmonary disease (OR =1.357,95％ CI 1.008-2.143),P＜0.05.Conclusion Combination with glucocorticoid,Hp infection,drug overdose,ulcer history,age ＞ 65 years old,non-specific inhibitor of COX-2,addicted to tobacco and alcohol history,concomitant chronic cardiopulmonary disease are risk factors of upper gastrointestinal injury induced bv NSAIDs.

Objective To do a longitudinal study of nursing undergraduates′ humanistic care ability in different period of clinical practice, and analyze its trend, aiming to provide reference about how to intervene to enhance the nursing undergraduates' humanistic care ability. Methods A total of 67 nursing undergraduates were investigated about their humanistic care ability with the Care Ability Inventory (Caring Ability Inventory, CAI) at the beginning, middle and end of the internship. Results The scores of seniors′ humanistic care ability at the beginning, middle and end of the internship were 194.97±22.93, 192.18±26.87, 187.24±22.15, and there was a statistically significant difference among the three time points (F=3.234, P<0.05), there was significant difference of the dimension of courage in different periods (F=7.511, P<0.01). Conclusions There is a downtrend of nursing undergraduates′humanistic care ability in different stages of clinical practice, and we suggest that nursing educators and administrators should consider the characteristics of different periods in the clinical practice, and then do a targeted training to foster nursing students′humanistic care ability.

It is to investigate the effect of two kinds of Houttuynia Cordata Injection on preventing and treating H1N1 influenza virus infection in mice. Pneumonia model was set up by intranasal infection of the normal and immunocompromised mice with influenza virus FM1 and PR8. The two injections were administered before and after the administration of virus, separately, and the lung index was observed. The results showed that the two preparations have obvious therapeutic effect on normal mice infected with influenza virus FM1 and PR8. And to FM1, the new injection's effect is better at small dosage. The results also showed that the two preparations have obvious prophylactic effect on immunodepressed mice infected with influenza virus FM1 and PR8. And to PR8, the old injection's effect is better at small dosage. Houttuynia Cordata Injection can improve the mice pneumonia caused by influenza virus H1N1 and decrease the lung index markedly. It has a remarkable preventive and therapeutic effect on H1N1 influenza virus in mice.

Objective The analysis of correlation between the occurrence of tourette syndrome with one-child family environment. Methods The authors investigated home environment of two groups. One group included 200 patients with tourette syndrome and is the other group included healthy children of the same age in 3 different primary and secondary schools. By comparing with the home environmental factors, parenting styles and parent emotional factors between two groups. Results The instabilities of home environment included bad family relationship, separation between parents, divorce, scolding and even beating children. It showed that anxiety of the direct supervisors among the sickness group were higher than healthy control group as well. Among the ten factors of the Family Environments Scale, the significant differences showed in six factors of affection,cohesion,expressiveness, conflict, intellectual-culture orientation, active-recreational orientation, organization between the two groups. Conclusion So we concluded that ①There is a correlation between the parents relations,parenting styles and the incidence of tourette syndrome; ②An anxiety of the direct supervisor may initiate, even aggravate the incidence of tourette syndrome; ③It is important to convert the education mode and take family overall treatment in order to reduce the incidence and improve the effectiveness of tourette syndrome.

AIM: To investigate the effect of silymarin on homocysteine-induced cell viability and apoptosis in human umbilical vein endothelial cells (HUVECs). METHODS: Cell viability was analyzed by using MTT and LDH assay. Apoptotic cells were detected by using DNA fragmentation and flow cytometric analysis. The level of intracellular reactive oxygen species (ROS) and the potential of mitochondrial membrane were determined by flow cytometric assay. The activity of caspase-3, -6 and -9 were measured with microplate spectrofluorometer. Protein levels were examined by Western blotting. RESULTS: Treatment of cultured HUVECs with HCY for 48 h induced a significant decrease in cell viability, and the percentage of apoptosis increased to 76.8%. The level of intracellular ROS and activity of caspase-3, -6 and -9 enhanced, and the red/green ratios of mitochondrial membrane decreased. However, simultaneous treatment with silymarin exhibited cytoprotective effects, reduced formation of the DNA ladder, prevented the levels of Bax and Bcl-2 proteins and the accumulation of ROS as well as caspase-3, -6 and -9 activation, reconverted the potential of mitochondrial membrane, and the percentage of apoptosis/necrosis was significantly decreased to 12.7% in a dose-dependent manner. CONCLUSION: These results demonstrate that silymarin has the protective capacity to antagonize HCY-induced apoptosis in HUVECs. The antiapoptotic action of silymarin may be partially dependent on an anti-oxidative stress effects, inhibition of caspases activity, and maintenance of mitochondria function.
