Objective To observe and investigate the influence degree of laparoscopic operation for the postoperative body stress and inflammatory state of patients with gastric and duodenal ulcer perforation.Methods 76 patients with gastric and duodenal ulcer perforation were selected as study subjects,and they were divided into control group(conventional open operation group)and observation group(laparoscopic operation group)according to the random number table,38 cases in each group.The serum body stress hormones and antiinflammatory,proinflammatory related indexes of the two groups at first day before operation and at first,third,seventh day after operation were respectively detected and compared.Results The serum IL -2 levels of the observation group at first,third and seventh day after operation were (3.53 ±0.24)μg/mL,(3.25 ±0.22)μg/mL and (4.37 ±0.33)μg/mL,which were higher than those of the control group(F =5.876,P <0.05),while other serum body stress hormones and antiin-flammatory,proinflammatory related indexes were all obviously lower than those of the control group (all P <0.05), there were significant differences between those postoperative evaluation results of the two groups.Conclusion The influence of laparoscopic operation for the postoperative body stress and inflammatory state of patients with gastric and duodenal ulcer perforation is relatively small,and it shows that the bad body stress degree caused by the operation is relatively smaller.

Objective To observe the effect of core stability training on the associated reaction of upper limbs in stroke patients with hemiplegia. Methods From November, 2014 to May, 2016, sixty stroke patients with hemiplegia were randomly divided into control group (n=30) and treatment group (n=30). Both groups accepted routine rehabilitation, while the treatment group received core stability training for 20 minutes during exercise. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Fugl-Meyer Assess-ment-Lower Extremities (FMA-LE), Berg Balance Scale (BBS) and Associated Reaction Rating Scale (ARRS) before and 6 weeks after treatment. Results The scores of FMA-UE, FMA-LE, BBS and ARRS improved significantly in both groups after treatment (t>12.158, P<0.001), and improved more in the treatment group than in the control group (t>2.317, P<0.05). Conclusion Core stability training can re-lieve the associated reaction of upper limb in stroke patients with hemiplegia.

Objectives To find out the effects of estrogen and clomiphene on behavior of epileptic rats induced by kainic acid (KA) and probe into some mechanisms. Methods Ovariectomized Sprague-Dawley female rats were treated with estrogen (E) or estrogen and clomiphene (C). Their behaviors when they were induced seizures were observed and compared. Indirect immunofluorescence method was used to measure the alterations of gamma-aminobutyric acid (GABA) immunoreactive cells and ?1 subunits of GABA_A receptors in the hippocampus of all groups. Results The latency and time at reaching 4/5 degrees in KA+E group ((24.63?11.44) minutes and (41.50?16.22) minutes, respectively) were reduced greatly than KA group ((46.75?14.61) minutes and (65.13?12.99) minutes), while the latency of (KA+)E+C group (adding estrogen and clomiphene, (43.50?5.75) minutes) became prolonged significantly than in KA+E group. Conclusion High-level estrogen should be proconvulsant and the clomiphene might have some antiepileptic effects, which may be related with some alterations of GABA energic function in the brain.

This study is to investigate the protective effect of astaxanthin against injured hepatocyte L-02 cells induced by sodium azide (NaN3) and reveal the possible mechanisms. Hepatocyte L-02 cells were exposed to 100 mmol.L-1 NaN3 with various concentrations of astaxanthin pre-incubated, then the cell viability was measured by MTT method; The level of reactive oxygen species (ROS) was determined by DCFH-DA method; The changes of mitochondrial membrane potential (MMP) and apoptosis ratio were detected by JC-1 method and Annexin V-FITC/PI double stain method, respectively. Results showed that after cells were exposed to 100 mmol.L-1 NaN3 for 3 hours, the cell viability significantly decreased; ROS level and the percentage of late phase apoptosis increased obviously; MMP was also declined. When cells were pretreated with astaxanthin, the cell damage and late phase apoptosis ratio reduced and MMP was maintained. However, the level of ROS showed insignificant decrease (P>0.05). The beneficial concentration of astaxanthin in improving cell viability and MMP was not in a dose dependent manner and the most effective of which was 0.10 nmol.L-1 (P<0.01). In order to reveal its possible non-antioxidant mechanism, mitochondrial membrane was imitated and H+ transferring function of astaxanthin was also detected by bilayer lipid membrane (BLM) method. Results showed that 2.0% astaxanthin could transfer H+ efficiently. These suggested the mechanisms of astaxanthin in protection of hepatocyte L-02 cells not via its ROS quenching capability but via its H+ transferring function, which improved the mitochondrial function and had the sequence biology effects.

Objective To study the expression of eyelooxygenase-2(COX-2)in invasive duetal carcinoma of breast and its relationship with cell prolireration and angiogenesis. Methotis Expression of COX-2 and Ki-67 was detected in 52 cages of breast cancer tissue by immunohistochemistry. CD34 marking vascular endothelial cell was used to measure the miemvascular density(MVD).Results The positive COX-2 expression was 57.7%in invasive duetal carcinoma of breast.The Ki-67 index was (56.07±17.37)%in COX-2 positive group while(27.32±16.28)%in the negative group,and the MVD W88 32.46±12.59 in COX-2 positive group while 25.04±10.48 in the negative group.The positive group of COX-2 protein had higher Ki-67 and MVD than that in negative group(P＜0.05).Conclusion The overexpression of COX-2 protein Were found in invasive ductal carcinoma of breast.To stimulate cell prolireration and angiogenesis may be one of the pathways of COX-2 protein to contribute to the invasion and metastasis in human breast cancer.

Objective:To investigate the influence of propofol on the binding function of GABA A receptor. Methods: By using radioligand receptor binding assay, effects of propofol on the specific binding of 3H GABA and saturation curves of GABA A receptor were observed in cortical membrane preparations from mouse cerebral cortex. Results: Specific binding experiments showed that propofol at the concentrations of 10 300 ?mol/L markedly enhanced the specific binding of 3H GABA( P 0.05). Conclusion: Clinical concentrations of propofol can enhance the binding function of GABA A receptor through increasing the affinity of the low affinity binding site of GABA.

Objective To explore effects of sulfentanyl preconditioning on myocardial injury in scald in diabetic and non-diabetic rats.Methods Eighty SD rats (40 diabetic rats and 40 non-diabetic rats)were divided into eight groups (10 rats per each),including sham group(group NS,non-diabetic rats with sham burn),burned group(group NB,non-diabetic rats with third-degree burns over 30%total body surface area (TBSA)and lactated Ringer??s solution for resuscitation),sulfentanyl group (group NP,non-diabetic rats without given sulfentanyl before burning and lactated Ringer??s solution for resuscitation)and naloxone group(group NN,non-diabetic rats given naloxone before sulfentanyl group),Diabetes sham group(group DS,diabetic rats with sham burn),Diabetic rats burned group (group DB,diabetic rats given third-degree burns,over 30 percent of the total body surface area had been burned and given lactated Ringer??s solution for resuscitation),diabetic sulfentanyl group(group DP,diabetic rats given sulfentanyl before burning and given lactated Ringer??s solution for resuscita-tion)and diabetic naloxone group(group DN,diabetic rats given naloxone,after that treated as the sulfentanyl group).Results Compared to group NB,for the mice in group NP,the activity of plasma SOD increased significantly,TNF-α,cTnI and water content level in myocardium decreased signifi-cantly (P <0.05 );whereas TNF-α,cTnI and water content level in myocardium in group DB in-creased significantly (P <0.05);Compared to group DB,for the mice in group DP,the activity of plasma SOD increased significantly,MDA,TNF-α,cTnI and water content level in myocardium de-creased significantly (P <0.05).Conclusion Diabetes may deteriorate burn-induced myocardial injury in rats.Sulfentanyl pretreatment exhibits significant protective effects on burned-induced myocardial injury in severely burned diabetic rats via inhibiting lipid peroxidation and TNF-αexpression.

Objective: In order to further investigate the structural/functional relationship of TRALL. Methods: We did homology modeling for the extracellular segment of TRAIL, which is from R117 to G281, totally 165 aa residues long. The modeling software is Insight II from MSI/Biosym and the modeling work is based on the three dimensional structure of TNF-?. Results: From the modeling result, it can be seen that the modeled structure of TRAIL contains 10 ?-sheets and homologs for all these sheets could be found in TNF-?. This just confirms with the principle that the structurally con-seived regions within molecules of the same structure family should experience relatively small sequence mutations. In addition, the credibility of the modeled structure is checked by the way of inverse folding from Profile-3D. Conclusion: The result shows modeled structure is generally correct.

Objective To investigate the relationship between smoking and insulin resistance in non-obese male patients with CAD. Methods 414 consecutive non-obese male patients with angiographically-documented CAD(luminal diameter narrowing>50%)were recruited,including 113 nonsmokers and 301 smokers.With 99 miht smokers(<400 packs/year),95 medium smokers(400-799 packs/year)and 107 heavy smokers(≥800 packs/year).Insulin resistance index(IRI)was expressed by homeostasis model assessment for insulin resistance(HOMA-IR)calculated by the formula of[fasting serum glucose(mmol/L)×fasting plasma insulin(mU/L)]/22.5.IRI≥2.69 was defined as insulin resistance,while IRI<2.69 was insulin sensitive.Fasting glucose,fasting insulin and IRI were recorded and odds ratio for the incidence of insulin resistance was calculated.Results Fasting glucose was higher in heavy smokers (5.86 mmol/L)than that in nonsmokers(5.51 mmol/L,P=0.037)and mild smokers(5.33 mmol/L,P=0.014).Fasting insulin and IRI were also significantly higher in heavy smokers(10.25 mU/L)than those in non-smokers(8.72 mU/L,P=0.0231,respectively)and mild smokers(8.67 mU/L,P=0.023 1).Compared with nonsmokers,the odds ratio for the incidence of insulin resistance was 1.53(95%CI 0.55-2.94;P=0.027)in medium smokers and 1.89(95%CI 0.49-3.14;P=0.018)in heavy smokers.Conclusions The relationship between smoking and insulin resistance is highly dose dependent in non-obese male patients with CAD.

Objective To explore the personality change in patients with epilepsy during the interictal period and the correlation between clinical features and personality change. Methods One hundred and fifteen patients with idiopathic or cryptogenic epilepsy were chosen as the epileptic group and 42 age- and sex-matched healthy subjects served as controls. All participants were evaluated by Mini Mental Status Examination and Brief Psychiatric Rating Scale to ensure the normality of cognition and mental state.Personality was evaluated by adult version of Eysenck Personality Questionnaire (EPQ)in interictal epilepsy patients and healthy controls.Scores of psychoticism (P),extraversion (E),neuroticism (N) and lie (L)were obtained using computer software. Pearson correlation analysis and logistic regression were used to investigate the scores of EPQ and influential factors.Results P and N scores were significantly elevated in epilepsy patients compared with controls ( P scores:50.48 ± 9.55 vs 46.59 ± 7.28,N scores:51.13 ±12.89 vs 46.83 ± 9.40 ; t =2.374,2.266,both P ＜ 0.05 ),while E scores were significantly decreased (51.74 ± 10.74 vs 60.37 ± 9.84;t =- 4.511,P ＜ 0.01 ).There were no significant differences in L scores.Multivariate analysis showed that disease duration was independently correlated to P scores (β =0.043,P＜0.05),while education was correlated to E scores (β =0.109,P ＜ 0.05 ).There were no significant correlations between personality scores,patient age,gender,age of onset,frequency,seizure type,National Hospital Seizure Severity Scale scores,family history,history of status epilepticus and antiepileptic drugs usage.Conclusions High psychoticism and neuroticism and low cxtraversion scores are correlated to patients with epilepsy during the interictal period.Disease duration is an independent risk factor for psychoticism personality,and education level is an independent risk factor for extraversion personality in epilepsy patients.
