Objective To explore the tridimensional personality characteristics of heroin addicts and the relationship with their mental state.Methods The personality character of 113 general adult and 100 heroin addicts were tested with tridimensional personality questionnaire(TPQ),and the mental state for the heroin addicts were tested with symptom of check- list(SCL-90) and to contrast the consequence with the norm of Chinese.Results NS and HA scores in heroin addicts( ( 18.07 ±4.13),( 16.06 ± 5.13) ) were higher than those in normal control group( ( 16.22 ± 4.88),( 13.98 ± 6.11 ) ) (P ＜ 0.05 ),and RD scores ( 17.22 t 3.18 ) was lower than that of the control group (18.27 ± 3.73 ),the difference was statistically significant (P ＜ 0.05 ).The total score of SCL-90 and 9 factors score of heroin addicts were higher than the national norm,the difference was statistically significant (P ＜ 0.01 ),in which somatization,obsession,depression and psychosis were more prominent ; HA scores in heroin addicts were positively associated with the factors including obsession,interpersonal relation sensitivity,depression and positive project number.The Pearson correlation coefficient were respectively 0.226,0.243,0.201,0.215,the difference was statistically significant (P＜ 0.05).Conclusion The personality characteristics of heroin addicts is special and is correlated with their mental health state.

ObjectiveTo explore the relationship between single nucleotide polymorphism analysis of a novel tryptophanhydroxylase isoform(TPH2)gene rs11178997and depression,and suicidal behavior.MethodsThe specimens of peripheral blood were collected from Chinese Northern 300 depression and 300 controis.The amplification of TPH2 gene rs11178997 was executed by realtime-polymerase chain reaction (realtime-PCR),and analyzed by directed sequencing.And the association between the polymorphisms of TPH2 gene and depression and suicidal behavior was analyzed with SPSS 17.0.ResultsThe genotypic frequencies of the SNPs did not deviate from Hardy-Weinberg equilibrium both in patient and control groups (P ＞ 0.05 ).Compared with control group,significant difference of genotypes and alleles of TPH2 gene rs1 1178997 single nucleotide polymorphism had been found in patient group (75.7％ vs 39.7％,6.0％ vs 1.3％,18.3％ vs 1.3％ ; P＜ 0.05 for all),and the AA genotype frequency of rsl 1178997 was significantly higher in patients.Meanwhile there were not significant differences between genotypes of TPH2 gene rs11178997 and suicide behavior in patient group.Suicidal behavior of depression patients in allele genotypes was higher than nonsuicide behavior of depression patients (P ＞0.05).ConclusionTPH2 gene rs4570625 single nucleotide polymorphisms have association with the susceptibility of depression.

Hippo signaling pathway plays a significant role in the development of colorectal cancer,and acts as an important regulatory pathway which regulates cell proliferation and cell differentiation.Multiple proteins and genes in Hippo signaling pathway,especially the downstream YAP protein,play important roles in the occurrence,metastasis,drug resistance and recurrence of colorectal cancer.YAP and other related genes can be used as targeted markers for predicting drug resistance to colorectal cancer.Hippo signaling pathway gene network can be used as targeted therapy or combination therapy,thus providing new ideas for the treatment of colorectal cancer.

Objective To evaluate left ventricular myocardial systolic function in patients with obstructive sleep apnea hypopnea syndrome ( OSA HS) with normal left ventricular ejection fraction( LVEF) using three‐dimensional strain echocardiography . Methods One hundred patients with OSA HS were divided into mild group ,moderate group and severe group according to apnea hypopnea index ( A HI) w hile matched with 32 healthy people as control group . T he parameters such as three‐dimensional LVEF ,global longitudinal strain( GLS) ,global circumferential strain( GCS) ,global area strain( GAS) ,global radial strain ( GRS) ,twist and torsion based on standard three‐dimensional echocardiography were measured by three‐ dimensional strain echocardiography , the above parameters among the four groups were compared for difference .Linear correlationship between A HI ,LVEF and the three dimensional strain parameters was analyzed respectively . Results ①T here was no significant difference in three‐dimensional LVEF ,twist and torsion between each groups( P ＞0 .05 ) . ②GLS ,GAS and GRS were lower in mild ,moderate and severe group compared with control group ,decreasing along with the disease severity ( P ＜0 .01 or P ＜ 0 .05 ) . GCS in severe group was lower than that in control group ( P ＜0 .01 ) . ③GLS and GAS in severe group were lower than those in mild group ( all P ＜0 .05) .GRS in moderate and severe group were lower than that in mild group( all P ＜ 0 .05 ) ,GAS ,GRS in severe group was lower than those in moderate group ( P ＜0 .05) . ④T here was a mild correlation between GLS and A HI ( r ＝0 .342 , P ＜0 .01) ,GAS and A HI ( r＝0 .294 , P ＜0 .01) ,GRS and A HI ( r ＝ －0 .411 , P ＜0 .01 ) . T here was a mild correlation between GCS and three‐dimensional LVEF ( r＝ －0 .354 , P ＜0 .01 ) ,GAS and three‐dimensional LVEF ( r ＝ －0 .326 , P ＜0 .01) ,GRS and three‐dimensional LVEF ( r ＝0 .300 , P ＜0 .01) . Conclusions T he left ventricular myocardial systolic function is impaired in all patients with OSA HS even with normal LVEF and the dysfunction is aggravating with the disease severity . Ultrasonic three‐dimensional strain imaging technology can be used to detect the subclinical myocardial systolic dysfunction quantitatively in the early stage of OSA HS patients .

Objective:To observe the changes of somatosensory evoked potential (SEP) in the upper limbs of patients with acute middle cerebral artery (MCA) cerebral infarction, and to explore its relationship with neurological impairment.Methods:From January 2015 to December 2016, 62 patients with 38 cases of male and 24 women of cerebral infarction who were treated in the department of neurology, Kailuan General Hospital were selected for a retrospectively prospective cohort study, including 38 males and 24 females.aged (66.7 ± 10.9) years old and ranging from 33.0 to 85.0 years old.According to the side of cerebral infarction, 37 cases were divided into left MCA group and 25 cases into right MCA group.During the 48 hours of admission, the electromyography evoked potential meter was used to detect the upper limb SEP, and the peak latency, amplitude and electrical activity waveform of the cerebral cortex potentials N20, P25 and N35 were recorded.Results:The results of SEP in the contralateral limbs of the left and right MCA cerebral infarction group were as follows: 1 case (2.70%) and 5 cases (20.00%) of normal median nerve; 36 cases (97.30%) and 20 cases (80.00%) of abnormality.The ratio of median nerve abnormalities in the group was statistically significant (χ 2=12.577, P<0.001). The ulnar nerve was normal in 3 cases (8.11%), 4 cases (16.00%); 34 cases (91.89%) and 21 cases (84.00%) were abnormal.There was no statistically significant difference between the two groups (χ 2=2.320, P=0.128). The peak latency and/or amplitude of each peak decreased in 34 groups (60.71%) and 33 cases (60.00%) of the ulnar nerve; the waveform of electrical activity disappeared, 22 cases (39.29%) of median nerve and 22 cases of ulnar nerve (40.00%). The peak latency and/or amplitude decreased, the electrical activity waveform disappeared, and the median nerve and ulnar nerve were compared, and the difference was not statistically significant (χ 2=0.021, P=0.885). The National Institue of Health Storke Scale(NIHSS) scores of left and right MCA cerebral infarction group were 34 (91.89%) and 19 (76.00%) respectively.Among them, the disappearance of electrical activity waveform were 18 cases (52.94%) and 4 cases (21.05%)of median nerve; 18 cases (52.94%) and 4 cases (21.05%) of ulnar nerve.The SEP electrical activity waveform disappeared in patients with moderate or higher neurological impairment, and the median nerve and ulnar nerve were statistically significant (χ 2=20.613, 20.613, all P<0.001). Conclusion:The median nerve and ulnar nerve SEP of the contralateral upper limb, which is dominated by the acute middle cerebral artery cerebral infarction, were abnormally changed.The main manifestations were that the latency of each peak of N20, P25 and N35 was prolonged and/or the amplitude was significantly decreased, and the waveform of SEP electrical activity disappeared.In addition, the disappearance of SEP wave activities only occurred in moderate and above neurological damage
