ABSTRACT
Objective@#Excessive daytime sleepiness (EDS) and insomnia symptoms are common in patients with major depressive disorder (MDD), which might lead to a poor prognosis and an increased risk of depression relapse. The current study aimed to investigate the prevalence, and sociodemographic and clinical correlates of EDS and insomnia symptoms among adolescents with MDD. @*Methods@#The sample of this cross-sectional study included 297 adolescents (mean age=15.26 years; range=12–18 years; 218 females) with MDD recruited from three general and four psychiatric hospitals in five cities (Hefei, Bengbu, Fuyang, Suzhou, and Ma’anshan) in Anhui Province, China between January and August, 2021. EDS and insomnia symptoms, and clinical severity of depressive symptoms were assessed using Epworth sleepiness scale, Insomnia Severity Index, and Clinical Global Impression-Severity. @*Results@#The prevalence of EDS and insomnia symptoms in adolescents with MDD was 39.7% and 38.0%, respectively. Binary logistic regression analyses showed that EDS symptoms were significantly associated with higher body mass index (odds ratio [OR]=1.097, 95% confidence interval [CI]=1.027–1.172), more severe depressive symptoms (OR=1.313, 95% CI=1.028–1.679), and selective serotonin reuptake inhibitors use (OR=2.078, 95% CI=1.199–3.601). And insomnia symptoms were positively associated with female sex (OR=1.955, 95% CI=1.052–3.633), suicide attempts (OR=1.765, 95% CI=1.037–3.005), more severe depressive symptoms (OR=2.031, 95% CI=1.523–2.709), and negatively associated with antipsychotics use (OR=0.433, 95% CI=0.196–0.952). @*Conclusion@#EDS and insomnia symptoms are common among adolescents with MDD. Considering their negative effects on the clinical prognosis, regular screening and clinical managements should be developed for this patient population.
ABSTRACT
Objective:To explore the correlation among childhood trauma, obsessive-compulsive symptoms, and implicit and explicit memory in patients with obsessive-compulsive disorder(OCD).Methods:Fifty-two OCD patients were enrolled, and the childhood trauma was investigated by using the childhood trauma questionnaire short-form(CTQ-SF). The degree of obsessive-compulsive symptoms was assessed by using the Yale-Brown obsessive symptoms scale (Y-BOCS). In addition, the abilities of implicit memory and explicit memory were tested by vocabulary perception speed tasks and vocabulary recognition tasks.According to the scores of CTQ-SF, the patients were divided into abuse group( n=26) and neglect group( n=26). SPSS 22.0 software was used for t-test and Pearson correlation analysis. Results:Results of obsessive-compulsive symptoms, implicit memory, and explicit memory showed no differences between the abuse group and the neglect group( t=-1.959-1.839, P>0.05). The scores of obsessions symptoms(12.52±4.61) were positively correlated with the total scores of CTQ-SF (40.10±10.20)( r=0.331, P<0.05). On the subscale, the scores of obsessions were positively correlated with the scores of physical abuse(7.89±3.02), sexual abuse(6.47±2.28)( r=0.373, P<0.01, r=0.356, P<0.05). There was a negative correlation between the scores of physical abuse and the accuracy of explicit memory(68.75±13.33)( r=-0.281, P<0.05). The scores of physical neglect(8.98±2.67) was positively correlated with implicit memory response time(4 285.94±2 067.42)( r=0.314, P<0.05). Conclusion:Obsessions in patients with OCD are related to traumatic childhood experiences, especially physical abuse and sexual abuse.Physical trauma may influence the level of implicit and explicit memory in patients with OCD.
ABSTRACT
Objective:To investigate the characteristics of attentional bias in adolescents with anxiety disorder.Methods:Totally 40 adolescents with anxiety disorder who met the DSM-5 diagnostic criteria were recruited as the case group, 40 normal adolescents matched with the case group in terms of gender, age and education level were served as the control group.Symptom was assessed by the screen for child anxiety related emotional disorders (SCARED), and attention bias was assessed by attention bias test on both groups.All data were analyzed using SPSS 21.0.Results:(1) In the test of attentional bias, the negative reaction of the case group was lower than the neutral response((647.14±94.44)ms, (661.08±112.07)ms), and the attention bias value of the case group was higher than the control group((13.93±33.27)ms, (-0.13±18.49)ms), the differences were statistically significant (both P<0.05). (2) In the total score and each factor score of SCARED, total score of SCARED was negatively correlated with the negative accuracy rate ( r=-0.38), and the separation anxiety score was negatively correlated with the negative accuracy rate ( r=-0.52), social terrorism scores were negatively correlated with negative accuracy ( r=-0.45) and neutral accuracy ( r=-0.43) (all P<0.05). The correlation between somatization, generalized anxiety and school terror with attention bias test were not significant( P>0.05). Conclusion:Adolescents with anxiety disorder are more concerned with negative stimuli, and it is difficult to shift attention from negative stimuli to others.The avoidance to neutral stimuli may be a risk factor for the severity of symptoms in adolescents with anxiety disorders.
ABSTRACT
Objective To investigate the effects of ZNF331 overexpression on proliferation and apoptosis of human colon cancer cell HCT116, and the relevant apoptotic mechanism.Methods The lentivirus vector of overexpressed ZNF331,Flag-pLV-Neo-ZNF331,was constructed and packaged.HCT116/p53 +/+(wild type p53)and HCT116/p53 -/-(deficient p53)cells were infected.Clones with ZNF331 overexpression were identified by Western blotting.Cell proliferation assay,colony formation assay and flow cytometry analysis were used to examine the effects of ZNF 331 on cell proliferation and apoptosis.Immunoprecipitation,luciferase reporter gene assay and real-time PCR were performed to detect interactions between ZNF331 and p53, p53 transcriptional activity and the expression of p 53 apoptotic target genes, respectively.Results The lentivirus vector of overexpressed ZNF 331 was successfully generated.Stable clones of ZNF331 overexpression were established.ZNF331 showed no significant effect on cell proliferation of HCT 116/p53 +/+, but inhibited cell proliferation of HCT116/p53 -/-(P<0.01).ZNF331 could interact with p53,dose-dependently inhibit the transcriptional activity of p53 and downregulate the mRNA levels of pro-apoptotic p53 target genes, Puma and p53AIP1 (P<0.05).ZNF331 could suppress p53-induced apoptosis(P <0.01).Conclusion The influence of ZNF331 overexpression on colon cancer cell proliferation is dependent on p 53 status.ZNF331 overexpression can suppress colon cancer cell apoptosis by interacting with p 53 and inhibiting the transcriptional activity of p 53.
ABSTRACT
OBJECTIVE:To investigate the effects of tirofiban combined with atorvastation before PCI on the miRNA expres-sion of peripheral blood and vascular endothelial function in acute myocardial infarction(AMI)patients. METHODS:A total of 80 patients with AMI selected from our hospital as reaserch objects during Jan. 2015-Jun. 2016 were divided into control group and ob-servation group according to random number table,with 40 cases in each group. Both groups received anticoagulant therapy. Con-trol group was given Aspirin enteric-coated tablets 300 mg+Clopidogrel sulfate tablets 75 mg+ Atorvastatin calcium tablets 20 mg orally 30 min before PCI. Observation group was additionally given Tirofiban hydrochloride for injection with initial dose of 0.5 mg+0.9％ Sodium chloride injection 100 mL,iv,then adjusted to pump injection of 0.4 μg/(kg·min),30 min later adjusted to pump injection of 0.1 μg/(kg·min),for consecutive 24 h. The levels of peripheral miRNA (miRNA-1,miRNA-133a,miR-NA-208b,miRNA-499),the levels of brachial artery diameter and vascular endothelial function indexes(vWF,ET-1,NO)were observed in 2 groups before medication and after PCI,and the occurrence of ADR was recorded. RESULTS:Before treatment, there was no statistical significance in above indexes between 2 groups(P>0.05). After treatment,miRNA expression,the levels of vWF and ET-1 were decreased significantly in 2 groups,and observation group was significantly lower than control group,with statistical significance (P<0.05). The brachial artery diameter and NO levels of 2 groups were increased significantly,and observation group was significantly greater or higher than con-trol group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLU-SIONS:For AMI,tirofiban combined with atorvastation before PCI can reduce miRNA expression,increase brachial artery diame-ter and protect vascular endothelial function with good safety.
ABSTRACT
Objective To compare the therapeutic effects of continuous veno-venous hemofiltration (CVVH) versus repeated intermittent veno-venous hemofiltration (RIVVH) on patients with severe acute pancreatitis (SAP).Methods Fifty-six patients with SAP were randomly divided into the CVVH group (n =28) and the RIVVH group (n =28).The clinical symptoms and signs,the APACHE Ⅱ and MODS scores,the result of biochemistry including amylase and lipase,and the plasma levels of TNF-α,IL-6,IL8 before and after treatment,the duration of mechanical ventilation,boosting drug application time,the length of stay in ICU,the surgical intervention rate and the mortality were compared between the two groups.Results The clinical symptoms improved in the two groups after treatment (P ＜ 0.05).The APACHE Ⅱ and MODS scores were all reduced in the two groups after treatment (P ＜ 0.05).When compared with the RIVVH group,the result of biochemistry including amylase and lipase,and the plasma levels of TNF-α,IL6,IL-8 were significantly decreased (P ＜ 0.05).The duration of mechanical ventilation,the length of stay in ICU and the mortality were also significantly decreased in the CVVH group (P ＜ 0.05).Conclusions CVVH was more efficacious than RIVVH in the treatment of SAP.
ABSTRACT
Objective To evaluate the effect of continuous blood purification (CBP) on cardiorenal syndrome (CRS) type Ⅰ.Methods Clinical data of 42 patients with CRS type [at our hospital were collected from January 2012 to June 2014.We observed and compared changes in mean arterial pressure (MAP),heart rate,respiration rate,acute physiology and chronic health evaluation (APACHE) Ⅱ score,and urinary volume before and 5 days after CBP.Meanwhile,levels of serum creatinine (Scr),cysteine proteinase inhibitor Cystatin C (CysC),serum creatinine (cTn) and B-type natriuretic peptid (BNP) were monitored.In addition,dynamic changes in cardiac index (CI),intrathoracic blood volume index (ITBI),global end-diastolic volume index (GEDI),central venous pressure (CVP),and extravascular lung water index (ELVWI) were monitored using the pulse induced contour cardic output plus monitoring system (PiCCO plus),and changes in left ventricular ejection fraction (LVEF) before and 5 days after CBP was measured by color Doppler ultrasound.Results There was no significant difference in MAP in patients with CRS type Ⅰ before and 5 days after CBP (P=0.08).Tacbycardia and tachypnea improved,while urine volume increased and the APACHE Ⅱ score decreased significantly,5 days after CBP(allP＜0.05).Plasma levels of Scr,CysC,cTn and BNP after treatment were lower than those before treatment [(126.8±68.3) μmol/L vs.(413.6±126.1) μmol/L,(1.1±0.8) g/L vs.(4.1±1.1) g/L,(2.6±0.4) μg/L vs.(3.5± 0.7) μg/L,(807.6±427.7) ng/L vs.(3300.3±567.6) ng/L,all P＜0.05)].Myocardial contractility,cardiac preload and lung related parameters also significantly improved after CBP (allP ＜0.05).Conclusions CBP can alleviate clinical symptoms of CRS type Ⅰ,improve cardiac and renal function,and is promising as an important auxiliary measure for the treatment of patients with cardiorenal syndrome type Ⅰ.
ABSTRACT
Clinical reproductive centers produce large amounts of surplus poor-quality embryos annually, how to maximize the use of these embryos, and which of them have the potential to develop into blastocyst stage and influencing factors were lack of systematic research. To investigate the fate of surplus poor-quality embryos which were cultured to obtain blastocyst, determine the factors which may influence the blastulation, and discuss their application in predicting of the pregnancy outcomes. Day 3 [D3] after embryo transfer and freezing, surplus poor-quality embryos from IVF/ICSI cycles were cultured to blastocyst by the sequential method, then the blastulation outcomes were observed. Focusing on the blastulation rate of those embryos with different number cells and different embryonic grade; and last the relationship between the pregnancy outcomes of remained poor-quality embryos with successful blastulation or failed blastulation groups were studied. Of 127 patients with 569 poor-quality in vitro cultured embryos, there were formation of 248 blastocysts from 91 patients [43.59%], which lead to development of 138 high-quality blastocysts [24.25%]. With the increase in cells number of D 3 blastomeres, the blastulation rate gradually increased, that, 7-cell blastomeres blastulation rate was the highest [70.59%], and 8-cell blastomeres is a little below [70.37%]; while the embryonic levels and blastulation rate did not show this positive relationship. The clinical pregnancy rate and implantation rate of those who had successful blastulation [67.03% and 42.39%] were higher than of those who failed to develop to blastocyst [p=0.039]. Day 3 poor-quality embryos with successful blastulation or with failed blastulation had predictive value on pregnancy outcomes. For embryo transfer 7-8 cells grade III-IV embryo is better than 4-5 cells grade I-II embryo, in case of lack good-quality embryos

Objective To explore humor experience and its relationship with theory of mind in patients with schizophrenia. Methods sixty?one schizophrenic patients without treatment and sixty?three healthy subjects were assessed with the Humor Picture Test ( HPT) ,Humor Video Test ( HVT) and the Theory?of?Mind Picture?Se?quencing Task ( ToM?PST) . Results Compared with healthy subject in HPT,schizophrenic patients showed sig?nificantly higher non?humor picture rating score (24.41 ± 8.82 vs 28.41 ± 11.56, P<0.05),and less humor picture rating score (45.65 ± 11.49 vs 34.41 ± 13.06, P<0.05). Compared with healthy subject in HVT,schizophrenic patients also showed significantly less humor video rating score (3.56 ± 0.57 vs 2.46 ± 0.79, P<0.01) and the number of standard humorous moments (3.68 ± 1.19 vs 2.42 ± 1.40, P<0.01) and the sensitivity of standard hu?morous moments?d’(humor) score (1.11 ± 0.46 vs 0.47 ± 0.42, P<0.01). Schizophrenic patients had significant?ly less total score (39.89 ± 12.33 vs 58.76 ± 0.64, P<0.01) of ToM?PST compared to normal control. Correlation analysis showed a negative correlation between d’ ( humor) score and the Positive and Negative Syndrome Scale ( PANSS) total score ( r=-0.380, P<0.01) for the patients. There was significantly negative correlation between non?humor picture rating score and ToM?PST total score ( r=-0.316, P<0.05) ,and positive correlation between d’ (humor) score and ToM?PST total score ( r=0.400, P<0.01) in schizophrenic patient. After controlling for the PANSS total score,the correlation between d’(humor) score and ToM?PST total score remained significant. Conclusion Schizophrenic patients have poor humor experience,which is related to the impairments of theory of mind.Humor experience deficit may share a common neuropsychological base with the impairment of theory of mind.
ABSTRACT
Objective To evaluate the effect of different blood purification modes on patients with hyperlipidemic pancreatitis (HLP).Methods 28 patients with HLP in our department were enrolled into this study from January 2010 to June 2013.The patients were randomly divided into the HP/CVVH group (15 patients) and CVVH group (13 patients).The clinical symptoms and signs of the two groups were observed.The plasma levels of TNF-α,IL-6,IL-8,blood triglyceride and APACHE Ⅱ score before and after treatment were compared between the two groups.The duration of mechanical ventilation,ICU stay and mortality rate were compared between the two groups.Results The clinical symptoms improved in the two groups after treatment.The plasma levels of TNF-α,IL-6,IL-8,blood triglyceride and APACHE Ⅱ score were all reduced.However,the plasma levels of TNF-o,IL-6,IL-8,blood triglyceride and APACHE Ⅱ score in the HP/CVVH group were lower than the CVVH group at the same time points,showing significant differences (P ＜ 0.05).The duration of mechanical ventilation,ICU stay and mortality rate decreased in the HP/CVVH group (P ＜ 0.05).Conclusions HP/CVVH was more efficacious in the treatment of HLP.
ABSTRACT
<p><b>BACKGROUND</b>Whether an addition of OAC to double antiplatelet therapy for patients with an indication of chronic oral anticoagulation undergoing PCI-S may improve clinical outcomes is still debated. This meta-analysis aimed to update and re-compare the benefits and risks of triple antithrombotic therapy (TT) with double anti-platelet therapy (DAPT) after in patients who requiring oral anticoagulation after percutaneous coronary interventions with stenting (PCI-s).</p><p><b>METHODS</b>Ten reports of observational retrospective or prospective studies were retrieved, including a total of 6296 patients, follow-up period ranging from 1 year to 2 years.</p><p><b>RESULTS</b>Baseline characteristics were similar in both groups. The main finding of this study is the overall incidence of major adverse cardiovascular events (MACE), myocardial infarction (MI) and stent thrombosis was comparable between two groups. Patients with TT was associated with significant reduction in ischemic stroke (OR: 0.27; 95%CI: 0.13 - 0.57; P = 0.0006) as compared to DAPT. We reaffirmed triple therapy significantly increased the risk of major bleeding (OR: 1.47; 95%CI: 1.22 - 1.78; P < 0.0001) and minor bleeding (OR: 1.55; 95%CI: 1.07 - 2.24; P = 0.02).</p><p><b>CONCLUSIONS</b>Triple therapy is more efficacious in reducing the occurrence of ischemic stroke in PCI-s patients with an indication of chronic oral anticoagulation (OAC), compared with DAPT. However, it significantly increased major and minor risk of bleeding. It is imperative that further prospective randomized controlled trials are required to defne the best therapeutic strategy for patients with an indication of chronic OAC undergoing PCI-s.</p>

<p><b>OBJECTIVE</b>To analyze the data of patients with clinical stage T1a lung adenocarcinoma and find the predictive factors associated with lymph node metastasis.</p><p><b>METHODS</b>From January to June 2012, 271 patients with small nodules of peripheral lung adenocarcinoma were enrolled in the retrospective review. There were 105 male and 112 female patients, with an average age of (61 ± 11)years (range 32-85 years). The data were collected including age, gender, smoking history, carcinoembryonic antigen(CEA), imaging findings, surgical procedure, pleural involvement, symptoms, tumor size, pathological classification, pathologic stage, maximum standardized uptake value(SUVmax) and lymph node metastasis. The predictive factors of lymph node metastasis in clinical factors were detected by univariate and multivariate analysis.</p><p><b>RESULTS</b>By preoperative thin-section CT, 35 patients were categorized as pure ground-grass opacity(GGO), 11 cases of atypical adenomatous hyperplasia, 24 cases of adenocarcinoma in situ, with no lymph node metastasis. Categorized as mixed ground-glass opacities in 89 patients, 84 patients (94.4%) had no lymph node metastasis, only 5 patients (6.0%) with lymph node metastasis. Categorized as solid nodules in 93 patients, a total of 28 cases (30.1%) had lymph node metastasis. There were statistically significant difference between three groups (χ(2) = 23.41, P < 0.001) . By univariate analysis, we found that the predictive factors of lymph node metastasis were as follows: tumor size > 1 cm (χ(2) = 9.021, P < 0.003) , imaging performance with mixed GGO or solid nodules (χ(2) = 23.41, P < 0.000) , CEA > 5 µg/L (χ(2) = 15.541, P < 0.000) and PET-CT SUVmax > 5 (χ(2) = 0.644, P < 0.000). By multivariate analysis, we found that imaging performance (mixed GGO or solid nodules) was the independent predictor of lymph node metastasis in clinical factors (OR = 166.116, 95%CI:18.161-25.19, P < 0.001) .</p><p><b>CONCLUSIONS</b>Patients of pure GGO generally do not have lymph node metastasis. Tumor diameter > 1 cm, imaging findings with the mixed GGO or solid nodules, carcinoembryonic antigen CEA > 5 µg/L, PET-CT SUVmax > 5 are predictive factors of lymph node metastasis in which imaging is independent predictor.</p>

BACKGROUND:Urokinase-type plasminogen activator (uPA) and urokinase-type plasminogen activator receptor (uPAR) are known as important factors, which mediate a variety of functions in terms of vascular homeostasis, inflammation and tissue repair. However, their role in systemic inflammatory response syndrome (SIRS) has been less well studied. This study aimed to test the hypothesis that the abnormalities of fibrinolysis and degradation of extracellular matrix mediated by uPA and uPAR are directly related to the patients with SIRS. We therefore analyzed their role and clinicopathological significance in patients with SIRS.METHODS:A case-control study was conducted with 85 patients who were divided into two groups according to the diagnostic criteria of SIRS:SIRS group (n=50) and non-SIRS group (n=35). The SIRS group was divided into MODS group (n=26) and non-MODS group (n=24) by their severity, and survival group (n=35) and non-survival group (n=15) by their prognosis. Another 30 healthy adults served as normal controls. uPA and uPAR in plasma were detected by commercial enzyme-linked immunosorbent assay (ELISA) kits.RESULTS:The plasma level of uPA was lower in the SIRS group than in the non-SIRS group and controls (P<0.001 andP<0.001). It was lower in sepsis patients and the MODS group than in the non-sepsis patients and the non-MODS patients (allP<0.05). However, there was no difference in uPA level between survivors and non-survivors (P>0.05). The plasma level of uPAR increased in the SIRS group compared with the non-SIRS group and controls (P<0.001 andP<0.001). There was a significant elevation of uPAR in sepsis patients, MODS patients and non-survivors as compared with non-sepsis patients, non-MODS patients and survivors respectively (allP<0.05). Plasma uPAR levels were positively correlated with APACHE II score (r=0.575,P<0.001) and SOFA score (r=0.349,P=0.013). AUCs for the prediction of SIRS mortality were 0.67 and 0.51, respectively, for uPA and uPAR.CONCLUSION:uPAR could be a predictor of poor outcome in patients with SIRS.
ABSTRACT
Objective To test plasma levels of uPA,uPAR,D-dimer,IL-6 and TNF-α,and observe the relationships between uPA,uPAR and D-dimer,IL-6,TNF-αin patients with SIRS.Methods A prospective,clinical case-control study was adopted.Cases were collected from our hospital in January 2008 to January 2010,and all were ＞ 55 years of age.Venous blood samples were collected via routine venipuncture.Eighty-five patients were divided into two groups according to diagnostic criteria of SIRS:SIRS group collected from Intensive Care Unit ( n =50) and non SIRS group collected from medical ward ( n =35).The control group comprised 30 unrelated healthy blood donors who visited the General Health Checkup Division at our hospital.Patients with (1) pregnant women; (2) cancer; (3) died after admitted into ICU in 7 days; (4) after cardiopulmonary resuscitation ; ( 5 ) with previous blood system diseases; (6) patients with SIRS before admitted into ICU were excluded from the study.uPA,uPAR,D-D,IL-6 and TNF-α in blood were detected by commercial enzyme-linked immunosorbent assay (ELISA) kits.The data was analyzed using SPSS version17.0.Data accorded with normal distribution of measurement was expressed as mean ± standard,and analyzed by independent-samples t test; non-normal distribution of measurement data,expressed by median,was analyzed with Mann-Whitney test.Relationships between plasma levels of uPA,uPAR and D-dimer,IL-6 TNF-α were analyzed using Spearman rank correlation test.To compare with blood level of uPA,uPAR,IL-6 and TNF-α in SIRS patients in the application of diagnostic value of MODS,we constructed the receiver operating characteristic curve ( ROC curve) for blood levels of uPA,uPAR,IL-6 and TNF-α in 24 h.Results The plasma levels of uPA,uPAR,D-dimer,IL-6 and TNF-αin patients of SIRS were obviously higher compared with non-SIRS and normal controls ( all P ＜ 0.01 ).Correlation analysis showed that there was positive correlation between uPAR level and IL-6 level (r =0.395,P =0.004) ; there was positive correlation between uPAR level and TNF-αlevel ( r =0.606,P ＜0.01 ).There was no correlation between uPAR levd and D-dimer level ( r =- 0.069,P =0.632).There was no correlation between uPA level and D-dimer,IL-6 or TNF-α ( all p ＞ 0.05).There ROC curve were made based on the abilities of uPAR,D-dimer,IL-6 and TNF-αlevels in 24 hours to diagnose MODS,and the ROC areas under the curves were 0.76,0.58,0.86,0.83 respectively.Conclusions These results demonstrate that uPA and uPAR play a major contributory role in patients with SIRS in the process of coagulation disorders,but the mechanism in SIRS is not the same.uPAR may play a central rolein the development of SIRS to MODS.
ABSTRACT
Objective To compare eye expression recognition in stable outpatients with schizophrenia with that in normal controls and to explore the relationships between eye expression recognition and social functioning.Methods 107 schizophrenic outpatients and 66 normal controls matched in age,sex and years of education were assessed with Eye Basic Emotion Discrimination Task(EBEDT) and Eye Complex Emotion Discrimination Task(ECEDT).The patients were also assessed with Social Disability Screening Schedule (SDSS).Results The correct numbers were significantly lower for patients to identify basic emotions of eye expressions(13.2±3.8 vs16.0±2.6,P<0.01) and complex emotions of eye expressions(17.9±4.3 vs 20.6±3.5,P<0.01)than those for controls respectively;the correct numbers to identify anger(3.1±1.0 vs.2.1±1.2,P<0.01),fear(1.8±1.0 vs 1.3±1.0,P<0.01) and disgust(1.8±1.1 vs 1.4±1.2,P<0.05)for controls were higher than those for patients significantly.The correct numbers to identify total basic emotions(r=-0.335,P<0.05)and total complex emotions (r=-0.374,P<0.05)in eye expressions showed negatively correlated with the total scores of SDSS in the patients after controlling age and total score of PANSS.Conclusions The ability to recognize basic and complicated emotions in eye expressions in the outpatients with schizophrenia is lower than that in the controls. It shows positively correlated with social functioning moderately in the patients.

ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of different concentrations of PPAR gamma agonist rosiglitazone on hypoxia/reoxygenation-induced oxidative stress, cell viability and apoptosis in rat cardiac myocytes.</p><p><b>METHODS</b>Cultured rat cardiac myocytes were divided into 5 groups, namely group I (normal group), group II (20 micromo/L ROS group), group III (I/R group), group IV (I/R+20 micromo/L ROS group), and group V (I/R+80 micromo/L ROS group). Group IV and group V were treated with rosiglitazone 12 h before hypoxia/reoxygenation. The changes in cell morphology were observed under optical and transmission electron microscopy, and levels of malondialdehyde (MDA), superoxide dismutase (SOD) activity, and lactate dehydrogenase (LDH) content were determined after the treatment. MTT assay was performed to assess the cell viability and flow cytometry was used to analyze the cell apoptosis.</p><p><b>RESULTS</b>Hypoxia/reoxygenation resulted in significantly increased MDA and LDH contents and apoptosis of the cardiac myocytes (P<0.05), but lowered SOD activity and the cell viability (P<0.05). The MDA and LDH contents and apoptotic rate were significantly lower but SOD content and cell vitality significantly higher in groups IV and V than in group III (P<0.05). Group V showed significantly lower MDA and LDH contents and apoptotic rate but higher but SOD content and cell vitality than group IV (P<0.05). Electron microscopy revealed obvious apoptotic changes in group III, and only mild changes were found in group V.</p><p><b>CONCLUSION</b>Rosiglitazone can significantly reduce hypoxia/reoxygenation-induced oxidative stress in cardiac myocytes, improve the cell viability and dose-dependently reduce the apoptotic rate of the cardiac myocytes.</p>
