ABSTRACT

Objective To explore the distributional differences of the gene frequencies of 22 short tandem repeats loci on Y Chromosome(Y?STRs) between offenders with Initiative?aggressive behavior and impulsive?aggressive behavior,and to probe into the genetic factors of initiative?aggressive behavior and im?pulsive?aggressive behavior. Methods Biological samples of 271 offenders with initiative?aggressive behav?ior and 271 offenders with impulsive?aggressive behavior were collected and PCR compound amplification was carried out with the aid of PowerPlex Y23 System. Then the PCR products were subjected to electrophoresis and gene detection with AB3500xL gene analysis system so as to calculate and compare the alleles and haplo?types of 22 Y?STRs gene frequency in the two groups. Results The distribution of allele frequency were sig?nificantly difference in locus DYS437(P=0.022) between two groups,not in the other 21 Y?STRs loci( all P>0.05) . Univarite analysis showed significant differences at allelle 14 in locus DYS437 between both groups ( initiative?aggressive behavior group:69. 37%;impulsive?aggressive behavior group:58. 67%; P=0. 009 ) . Conclusion Loci DYS437 may be associated with aggressive behavior. In the group of aggressive behavior, allelle 14 on locus DYS437 may be the susceptible factor of initiative?aggressive behavior and the resistant factor of impulsive?aggressive.

ABSTRACT

Objective To investigate the differential expression of microRNA (miRNA) in schizophrenia (SZ) patients,and explore the comorbidity of SZ and depression disorder based upon miRNA expression.Methods Affymetrix array analysis was used to investigate the differentially expressed miRNA in SZ patients firstly,and then quantitative real-time polymerase chain reaction (qRT-PCR) was further carried out to confirm the selected miRNA in peripheral blood mononuclear cells of 40 SZ patients,whom were administered by Positive and Negative Syndrome Scale (PANSS) and the selected miRNAs in depression disorder patients has also been confirmed by Affymetrix array analysis and qRT-PCR in our previous studies.Results Affymetrix array analysis indicated that there existed 33 miRNAs which differentially expressed (32 up-regulated and 1 down-regulated) compared with normal controls.qRT-PCR results suggested that the expression of 8 miRNAs (miR-1273d,miR-1303,miR-3064-5p,miR3131,miR-3687,miR-4428,miR-4725-3p and miR-5096) were significantly up-regulated in SZ;the miRNA differentially expressed in depression disorder patients also had differential expression in SZ patients (P<0.05).There were significant correlation between the miRNAs differentially expressed in depression disorder patients and in SZ patients (P<0.01).MiR-1972 differentially expressed in depression disorder patients had significant positive correlation with the positive symptoms of PANSS (P<0.05),and miR-26b was positively correlated with composite factor (P<0.05).Conclusion Comorbidity of SZ and depression disorder is observed not only on the clinical symptoms,but on the molecular genetic basis.

ABSTRACT

<p><b>OBJECTIVE</b>To assess the association of short tandem repeats (STRs) loci with aggressive behaviors of schizophrenia.</p><p><b>METHODS</b>Blood samples from 123 schizophrenic patients with aggressive behaviors and 489 schizophrenic patients without aggressive behaviors were collected. DNA from all samples was amplified with a PowerPlex 21 system and separated by electrophoresis to determine the genotypes and allelic frequencies of 20 STR loci including D3S1368, D1S1656, D6S1043, D13S317, Penta E, D16S639, D18S51, D2S1338, CSF1PO, Penta D, TH01, vWA, D21S11, D7S820, D5S818, TPOX, D8S1179, D12S391, D19S433, and FGA.</p><p><b>RESULTS</b>All of the 20 STR loci have reached Hardy-Weinberg equilibrium in both groups. A significant difference was found in allelic and genotypic frequencies of loci Penta D between the two groups (alleles: P=0.042; genotypes: P=0.014) but not for the remaining 19 loci (P> 0.05). Univariate analysis also showed a significant difference for allele 10 and genotypes 10-12 of Penta D between the two groups (P=0.0027, P=0.0001), with the OR being 1.81 (95%CI: 1.22-2.67) and 4.33 (95%CI: 1.95-9.59), respectively.</p><p><b>CONCLUSION</b>Penta D may be associated with aggressive behaviors of schizophrenia. Allele 10 and genotypes 10-12 of Penta D may confer a risk for the disease.</p>

ABSTRACT

Objective To investigate the serum retinol-binding protein 4 (RBP4) level in olanzapinetreated schizophrenia with non-alcoholic fatty liver disease (NAFLD) via a case-control study and to explore its relationship with NAFLD.Methods Schizophrenia receiving olanzapine treatment,with or without NAFLD were enrolled as cases (n=60) or controls (n=60).The serum retinol-binding protein 4,metabolic syndrome component including body mass index (BMI),waist-to-hip ratio (WHR),fasting plasma glucose (FPG),total cholesterol (TG),total glycerin (TC) and blood pressure were assayed.TyG index,CT value ratio of liver and spleen were used for insulin resistance or NAFLD diagnosis and severity assessment respectively.Results The serum level of RBP4 was significantly higher in cases than that in controls ((70± 13)mg/L vs (52±12)mg/L ; t =4.943,P<0.01) and the same result was showed after influencing factor adjustment thru covariance analysis (F=16.797,P<0.01).Moreover,cases had significantly higher TyG index,BMI,WHR,FPG,TG and systolic pressure (t=2.383-4.300,P<0.05-0.01).Cases with severe or moderate NAFLD had significantly elevated serum RBP4 level compared with mild cases((79± 16) mg/L,(72±8) mg/L vs (63t9) mg/L,d =16.2,9.9 ; P<0.01,0.05).A significantly negative correlation between RBP4 level and the CT value ratio of liver and spleen (r=-0.244,P<0.05),and a significantly positive correlation between RBP4 level and TyG index,BMI,WHR,TG(r=0.197-0.244,all P<0.05) were observed.The partial coefficient between RBP4 level and CT value of liver and spleen was significant with influence adjusted(r=-0.453,P<0.01).Logistic regression showed that serum RBP4 level(β3=0.105,P<0.01)and TyG index,hyperlipidemia,obesity,central obesity or high blood pressure (β =1.288-9.711,P< 0.05-0.01) were closely associated with NAFLD.Conclusion A heighten serum RBP4 level may be one of NAFLD risk factors in schizophrenia treated with olanzapine.

ABSTRACT

Objective To explore the effect of nitroglycerin on ET/NO, TXA2/PGI2 and pancreas pathomorphology changes in severe acute pancreatitis (SAP) rats. Methods Sixty SD rats were random divided into five groups, including control group (A group, n = 12) and experimental group(B,C,D and E group, n = 12). The SAP was induced by injection of 5% sodium taurocholate through retrograde common biliopancreatic ducts via duodenal papilla with epidural catheter. Group C, D and E were intravenously injected with nitroglycerin 0.5μg/kg/min,1μg/kg/min and 2μg/min in 30 min respectively, and group A and B was injected with Sodium Chloride 0.5ml. The indexes of changed pathomorphology and ET/NO, TXB2/6-keto-PGF1a, were determined at the 6th and 12th hour after operations, respectively. Results The specimen data of the 6th and 12th hour displayed that the indexes of changed pathomorphology, ET, ET/NO, TXB2, and TXB2/6-keto-PGF1a of the group C,D and E degraded respectively, compared to group B(P < 0.05). Conclusion The nitroglycerin could degrade ET, ET/NO,TXA2 and TXA2/PGI2, improve the microcirculation of pancreas, and delay the pathological inflammation change in SAP rats.

ABSTRACT

Objective To study the treatment of intra-abdominal hypertension syndrome (IAHS) secondary to fulminant acute pancreatitis(FAP). MethodsWe retrospectively analyse therapeutic results of 14 IAHS cases secondary to FAP during the period of 1998~2003. ResultsFour out of the 6 cases receiving nonoperative therapy died with motality rate of 67.7% (4/6). Two out of the 8 cases treated by early surgery died. The motality rate was 25% (2/8), which was significantly different from that treated conservatively . ConclusionModerate to severe IAHS cases secondary to fulminant acute pancreatitis should undergo exploration in the early phase of disease to improve the prognosis of FAP.
