Objective: To investigate the influence of ischemic and pinacidil preconditioning on the activity of NF-?B and its myocardial protective effects.Methods: Eighty isolated rabbit hearts were randomized into five groups(Group C?K?I?P?G).Hearts were removed and mounted in a Langendorff apparatus perfused with 37℃ oxygenated Krebs-Henselet buffer.All groups were subjected to gobal myocardial ischemia for 40 min and reperfusion for 60 min or 120 min.Cardiac functions were monitored at 10 min equilibration ?15 min?30 min?60 min and 120 min reperfusion;Coronary flow(CF) was measured at 10 min equilibration and 30 min reperfusion;Expression of NF-?B P65 was determined at 10 min equilibration?60 min and 120min reperfusion.Results:(1)After ischemic reperfusion,the recovery of cardiac function and CF in Group I and Group P was significantly superior to that in Group C and Group K(P

[Objective]To establish a scoring standard of operative risk assessment for the orthopaedic surgery and evaluate the reliability of it.[Method]Anivariable analysis was performed for the preoperative and intraoperative clinical data of 768 patients undergoing orthopaedic surgery from Jan.2001 to Dec.2008,the risk factors associated with orthopaedic surgery were selected.Then multivariable analysis with logistic regression was performed for the selected risk factors.The scoring standard was made through these data.Reliability of the standard was evaluated by predicting of 160 patients in spinal surgery from 2006 to 2008,comparing with the real situation of each operation.[Result]Anivariable analysis showed age,heart function,blood pressure,electrocardiogram,sternum,liver function,renal function,albumin,blood sugar,number of operative variables within four weeks,magnitude,blood loss preoperation,timing of operation were risk factors.[Conclusion]The ORAOS could appropriately predict the occurrence of patients' postoperative complication before operation.

To discuss long-term changes of refractive status in children after congenital cataract intraocular lens ( lOL) implantation and analyze its related influence factors.METHODS: Seventy cases ( 110 eyes ) with congenital cataract from January 2013 to January 2014 in our hospital were selected, according to the age of patients, they were divided into group A (<2 years old), group B (2~6 years old) , group C ( 7 ~ 12 years old ) . They were all given cataract extraction combined with lOL implantation in congenital cataract. Corneal curvature, axial length, refractive status of three groups after operation were compared, the influence factors ocular axis changes were analyzed. RESULTS: There were no statistically significant differences in corneal curvature of groups A, B, and C after operation ( P>0. 05 );The differences had statistical significances of the corneal curvature of group A after surgery and 3mo after operation (P<0. 05), there were no significant differences of the corneal curvature of group B, group C after surgery and 3mo after operation (P>0. 05);the corneal curvature 3mo after operation of group A was significantly higher than that of groups B and C (P<0. 05), there were no significant differences in the corneal curvature between group B, and group C after 3mo ( P>0. 05 ); There were no statistical significances on axial length after operation in groups A, B, and C (P>0. 05);Ocular axial length difference of group A 3mo after surgery was significantly higher than that of groups B and C ( P < 0. 05 ), ocular axial length had no statistical difference of group B, group c 3mo after surgery ( P>0. 05). Refractive status of three groups after operation showed myopia moving trend, refractive change rate and refractive diopter of group A after operation was significantly higher than that of group B, group C, the difference was statistically significant (P<0. 05). CONCLUSlON: After congenital cataract extraction combined with lOL implantation, patients present myopia refractive state trend. Performance of children below 2 years old is significant. The main factor of myopia is axial growth.

Objective To observe the effect of Risperdal combined with occupational therapy on chronic schizophrenia.Methods 30 patients with chronic schizophrenia,who treated by Risperdal with adequate dose and sufficient course but still had negative symptoms,received a 12-week occupational therapy training(the dosage of Risperdal not changed).The patients were assessed using Scale for the Assessment of Negative Symptom(SANS)and In-patient Rehabilitation Rating Scale(IPROS)before and after occupational therapy.Results After occupational therapy,patients' SANS scores decreased significantly(P<0.01),and social function improved significantly(P<0.05).Conclusion Risperdal combined with occupational therapy can further improve the negative symptoms of patients with chronic schizophrenia and promote their social function.

Objective To analyze the effects of TGF-β1 and p53 on expressions and mutations in smoked lung tissues.Methods Smoked rats model was built.The expressions of TGF-β1 and p53 in lung tissues were observed by immunohistochemistry.The expressions of TGF-β1 mRNA in lung tissues were observed by trans-reverse polymerase chain reaction (RT-PCR).The mutations of p53 in exon 5,6,7-8 were analyzed by polymerase chain reaction single-strandconformational polymorphism (PCR-SSCP).Results The expressions of TGF-β1 in normal lung tissues were faint,and the expressions increased along with the smoking months (P ＜0.05).The positive ratio of protein expression was increased with prolonging smoking time.The mutation of p53 was increased with smoking time.The p53 exons 5,6,7-8 have mutations respectively.The ratio of mutations increased along with smoke months.Conclusion The expressions and mutations of TGF-β1 and p53 increase along with smoked time,which can be regarded as references for lung cancer diagnosis.

ObjectiveTo observe the clinic effect of Xueshuantong in subacute cerebral hemorrhage. Methods60 patients with cerebral hemorrhage were randomly divided into treatment group and control group, each grous 30 cases. The control group, only to conventional treatment, the control group addded Xueshuantong 300mg intravenous drip. On the basis treatment in 7 ～21 days of cerebral hemorrhage both groups were checked the NIHSS score and head CT. Before and after the teatment. ResultsAfter 21days,the hematoma volume in the treatment group was ( 3.3 ± 2. 6) ml, the control group was( 7.2 ± 3.7 ) ml, Treatment group was significantly better than the control group (t =4. 102,P ＜ 0.05 ). NIHSS score of treatment group was (4.7 ± 2.8 ) points, the control group was ( 8.6 ± 3.3 )points. Treatment group was significantly lower than the control group( t =5. 329,P ＜ 0.05). ConclusionXueshuantong could promote the absorption of hematoma and the nerve function recovery in subacute cerebral hemorrhage.

Objective To explore the effect of nursing intervention on rehabilitation of stroke patients with hemiplegia.Methods 60 cases of hemiplegic patients after stroke were divided into the control group and the experimental group with 30 cases in each group randomly.The rehabilitation status was evaluated and compared using self rating depression scale (SDS) and activities of daily living (ADL) scale before and after intervention.Results After nursing intervention,ADL score and SDS score were better,treatment effect was also better,but SDS total score showed no significant difference.Conclusions Nursing intervention can effectively reduce or eliminate depression of patients after stroke,strengthen subjective initiative of patients,so that patients can actively cooperate with the treatment,and promote disease rehabilitation.
