Objective To explore psychological defense mechanism and its relationship with personality in patients with hysteria(HyS). Method Both HyS patients (n=30) and normal control(NC, n=66) comple-ted Defense Style Questionnaire (DSQ) and Eysenck Personality Questionnaire(EPQ) . Results The scores of projection, isolation, somatization and the factor scores of immature defenses were significantly higher in HyS pa-tients(3.64±1.45, 5.63±2.29,5.33±2.36 and 4.74±1.27, respectively) than those in NC [(2.61±1.09,4.33±2.02, 3.86±1.60 and 3.98±0.91, respectively) (all P<0.01)]. The scores of undoing, idealization, pseudo-altruism and the factor scores of neurotic defenses were also significantly higher in HyS patients compared with NC(P<0.01). The scores of suppression, humor and the factor scores of mature defenses and the lie were found lower significantly in HyS patients compared with NC (P<0.05). The scores of the neuroticism, psychoticism and lie subscale of EPQ in HyS patients were significantly higher than that of NC(P<0.01). The scores of extro-vert subscale were not found difference significantly between HyS patients and NC. The results of correlation analy-sis showed that the scores of the psychoticism subscale of EPQ in HyS patients correlated negatively with the factor scores of mature mechanism and the scores of suppression. Conclusion The HyS patients were more likely than the normal control to endorse the immature mechanism and neurotic defense and less likely to endorse the mature mechanism, which related with unhealthy personality, especially the psychoticism.

Objective:To explore the executive function of neuroleptic -naive and short -term medicated onset schizophrenic patients.Methods:55 drug naive patients and 49 patients with schizophrenia medicated for one month and 60 normal controls were administered the Wisconsin Card Sorting Test(WCST) to study the executive function.Results:Compared with the controls,neuroleptic-naive patients and medicated patients showed higher level in the number of total trials,perseverant errors,random errors,the rate of error responses and the rate of random errors,while they showed lower level in the number of categories,correct trials and the rate of correct responses.There was no significant difference in WCST between the neuroleptic-naive patients and medicated patients.Conclusion:Neuroleptic-naive and short-term medicated onset patients with schizophrenia may have executive dysfunction.

Objective:To study influence of insulin on myocardial microcirculation of patients with coronary heart disease (CHD)complicated type 2 diabetes mellitus (T2DM)after percutaneous coronary intervention (PCI).Meth-ods:A total of 65 patients,who was confirmed as CHD by coronary angiography and fractional flow reserve (FFR)<0.75 measured by pressure guidewire,were enrolled.After drug-eluting stent implantation,index of microcircula-tion resistance (IMR)was measured.According to insulin usage or not,they were divided into insulin therapy group (insulin group,n=30)and pure oral hypoglycemic agent therapy group (pure hypoglycemic agent group,n=35). After six-month follow up,IMR was reviewed,and IMR was compared between two groups.Results:There was no significant difference in incidence rate of major adverse cardiovascular events (MACEs)between two groups,P =0.07. On six months after PCI,IMR in insulin group was significantly lower than that of pure hypoglycemic agent group [(24.5±3.1)U vs.(30.2±4.3)U,P <0.05].Conclusion:Insulin therapy can improve myocardial micro-circulation in patients with coronary heart disease complicated type 2 diabetes mellitus after PCI.

Objective:To explore influence of percutaneous coronary intervention (PCI)on brain natriuretic peptide (BNP)level and ventricular remodeling in patients With acute ST elevation myocardial infarction (STEMI).Meth-ods:According to their therapeutic methods,a total of 151 patients diagnosed as STEMI Were divided into group A (n=52,received emergency PCI treatment),group B (n=49,received selective PCI treatment)and group C (n=50,received standard medication).BNP level and left ventricular remodeling Were compared among three groups before treatment and after treatment.Results:There Was no significant difference in BNP level among three groups before treatment (F=0.01,P>0.05),BNP level significantly decreased among three groups after treatment,com-pared With group B and C,there Was significant decrease in BNP level [(466.2±113.5)ng/L vs.(601.4±126.7) ng/L vs.(242.7±101.3)ng/L]in group A (P<0.01 all).There Were no significant difference in left ventricular end-diastolic volume (LVEDV),left ventricular end-systolic volume (LVESV),left ventricular ejection fraction (LVEF)and left ventricular fractional shortening (LVFS)among three groups before treatment (P>0.05 all);af-ter treatment,there Were significant increase in above ventricular indexes in three groups (P<0.05 all),compared With group C,there Were significant increase in LVFS [(22.6±6.9)% vs.(28.9±7.6)% vs.(27.5±7.3)%]in group A and B,compared With group B and C,there Was significant increase in LVEF [(53.1±6.5)% vs.(50.9± 5.7)% vs.(57.9±6.2)%]in group A (P<0.01 all).Conclusion:PCI could effectively improve ventricular re-modeling and decrease BNP level in STEMI patients,and emergency PCI shoWs more significant therapeutic effects than selective PCI.

Objective: To evaluate the defense mechanisms most frequently used by Chinese patients with panic disorder.Methods: Forty-seven panic patients with or without agoraphobia,and thirty-senven controls participated in the study.The Hamilton Depression Scale(HAMD,Hamilton Anxiety Scale(HAMA) and global assessment function(GAF) were applied to assess the severity of depression and anxiety symptoms and social and occupational function,respectively.Defensive Style Questionnaire(DSQ-88) was used to evaluate defense mechanisms.Results: Compared with controls,panic patients had higher scores in projection,splitting,regression,somatization and total scores of immature defenses and higher scores in idealization,pseudo-altruism,omnipotence-devaluation,attiliation and total scores of neurotic defenses(P

Objective To explore the cause and the interventional treatment of restenosis after percutaneous transhepatic biliary stent.Methods 20 patients with biliary restenosis after percutaneous transhepatic biliary stent placement were collected.According to drainage volume from biliary tract and degree of amelioration of jaundice,post-operation hepatic function,blood,urine and stool routines,ultrasound,CT scan and cholangiography were performed to determine the nature and location of biliary restenosis,and then all cases underwent recanalization with intervention method by the exteriorized drainage tube approach.The China-made nickel-titanium alloy stents with diameter of 10 mm and length ranged from 40 mm to 80 mm were used.Results The biliary restenosis occurred in mid-inferior segment of common bile duct in 9 patients, common hepatic duct in 7 patients and hepatic porta in 4 patients. As regarding the causes of restenosis included tumor compression in 9 cases, angulation in upper segment of stent in 3 cases, obstruction in stent by bile, food or clot in 4 cases, cholangitic stenosis in 2 cases and granulation proliferation in 2 cases.The obstruction in all cases was relived by extraction through drainage tube, drug irrigation,dredging by wire, balloon dialtion or stent replacement, so that the total survival rate was beyond 6 months.Conclusion After percutaneous transhepatic biliary stent placement in treating the malignant biliary obstruction,the rate of biliary restenosis is still high,which should be attached importance to.

ObjectiveTo establish the rat model of multi-infarct dementia. MethodsSephadex (4 mg/ml, 8 mg/ml) was injected into the internal carotid artery through the common carotid artery. Neurological deficits were measured 24 h after the operation, and Morris water maze test as well as Nissl stain were observed 26～30 d after the operation. ResultsThere was significant difference between the model groups injected sephadex of 8 ml/ml and 4 mg/ml in the neurologic deficits. In the following experiment, the rats injected sephadex of 8 mg/ml were only used as model. For the water maze test, the escape latency was longer (P＜0.01) and the frequency across target area reduced (P＜0.01) in the model, while the apoptotic Nissl body could be observed. ConclusionA model of multi-infarct dementia could be established with the sephadex in rats.
