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 study the effect of lactate of differentconcentration on the action potential of ventricular papillary muscle cell (n=4) and contractile force (n=10).Method Using intracellular microelectrode technique and microtension depicting method.Result The Result showed the effect of lactated solution of a certain comcentration became obvious. After perfused with lactate solution of 4mmol/L,the vilocity maximum decreased significantly (p<0.05) showed the 4mmol/L lactate solution decreased the rate of depolarization: decreased the efficency of Na + channel; lactate solution decreased the contractile force of cardiac muscle. Conclusion The possible mechanism was: Ca+ influx and Na+ - H+ exchange were inhibited, resulted in the elevation of intracellular H+ concentration; through Na+-Ca2+ exchange, Ca2+ efflux decreased resulted in the intracellular Ca2+ decreased resulted in the intracellular Ca2+ overload.

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 To investigate the expression of insulin-like growth factor 2 receptor(IGF-2R)induced by hypoxia and serum deprivation(H/SD)in cultured neonatal rat cardiomyocytes in vitro.Methods Cultured neonatal rat cardiomyocytes were randomly divided into control group and H/SD group.Expression of IGF-2R mRNA was measured by RT-PCR and real time RT-PCR.Level of IGF-2R protein was measured by enzyme-linked immunosorbent assay(ELISA).Results Compared with control group,the expression of IGF-2R mRNA increased significantly (P ＜0.01)in cardiomyocytes cultured in H/SD condition for 12 h and 24 h,and IGF-2R protein was upregulated in cardiomyocytes cultured in H/SD condition for 24 h(P ＜0.05).Conclusion H/SD may induce IGF-2R expression,and IGF-2R may potentially explain the mechanism of cardiomyocyte damage induced by ischemia.

BACKGROUND:Matrix metal oproteinase-13 is most active in the degradation of col agen type II in the extracel ular matrix of cartilage. Interleukin-1 (IL-1) is thought to be the inducer of matrix metal oproteinases, and participates in the degradation and degeneration of articular cartilage. OBJECTIVE:To study the influence of IL-1βon microRNA-27b (miR-27b) and matrix metal oproteinase-13 expression of chondrocytes in rats. METHODS:Chondrocytes isolated from seven male Wistar rats were cultured and divided into IL-1βstimulation group and control group. No stimulus was given in the control group;10μg/L of serum free medium was used to culture rat chondrocytes in the IL-1βstimulation group. Cel growth was observed at 0, 24, and 48 hours under an inverted microscope. miR-27b and matrix metal oproteinase-13 expression in the cultured chondrocytes were detected. RESULTS AND CONCLUSION:The relative expression of matrix metal oproteinase-13 in rat chondrocytes was gradual y increased when induced by IL-1βat 0, 24, and 48 hours (P<0.05). Expression of miR-27b and miR-31 in rat chondrocytes at 24 and 48 hours induced by IL-1βgradual y decreased (P<0.05);conversely, expression of MiR-26a, miR-26b, miR-23, and miR-204 gradual y increased (P<0.05). After 48 hours of IL-1βinduction, expression of miR-27b was the lowest in rat chondrocytes (P<0.05). These findings suggest that IL-1βinhibits miR-27b expression, strengthens the expression of matrix metal oproteinase-13, and damages chondrocytes, contributing to both the onset and progression of osteoarthritis.
