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.

Objective To study the characteristic findings of computer tomography (CT) and magnetic resonance imaging (MRI) in hepatobiliary cystadenocarcinoma.Methods CT,MRI and clinical data were analysed retrospectively.Plain,dynamic CT and MRI were performed in all patients.Results There were 8 patients,7 female,1 male,aged 48-74 years,with a median age of 58.Five lesions were in the left liver,and 3 lesions were in the right liver.One lesion was multilocular cysts with septations.Seven lesions were solitary.The lesions showed low or mixed density on plain CT.Two cysts showed evidence of hemorrhage,while 3 cysts showed fluid levels.There were different signal intensities in the cystic wall nodules which could appear as slightly low intensity on T1WI or slightly high intensities on T2WI.The cyst wall and septations appeared as slightly low intensity on T1WI and T2WI.The cystic fluid signal intensity changed with liquid ingredients.The nodularities showed obviously high signal intensity on DWI,and the fluid showed slightly high signal,while the cystic wall and separations showed slightly low signal intensity.On CT and MRI dynamic enhancement scanning,the nodularities showed obvious enhancement on the arterial phase,while the cystic wall and separations showed no enhancement.The nodularities showed persistent enhancement on the portal venous and delayed phases while the cystic wall and separation showed slight enhancement.Conclusions Hepatobiliary cystadenocarcinoma showed characteristic features on MSCT and MRI.MSCT combined with MR is an important method in the diagnosis and differential diagnosis of hepatobiliary cystadenocarcinoma.

Objectives To study the value of CT and MRI in diagnosing focal nodular hyperplasia (FNH).Methods The CT and MRI findings of 16 patients with FNH confirmed histopathologically were analyzed retrospectively.Both plain and dynamic enhanced CT scannings were performed in all the patients.Plain and dynamic enhanced MRI were carried out in 9 patients.Results (1) There were 16 patients with 19 lesions,and 8 lesions were in the left lobe,5 lesions in the right lobe,4 lesions between the left/right lobes and 2 lesions in the caudate lobe.The morphology of the lesions showed 15 lesions to have clear boundaries and 4 lesions to have fuzzy boundaries.The tumor diameters varied from 2.2 to 9.6 cm,(average 4.3 cm).(2) Sixteen patients underwent CT examination.On plain CT,the lesions were isotonic (n＝ 5),or slightly low-density (n=11).In 7 lesions,there was a slit-like,stellate-shaped low density central scar.Nine patients underwent MRI examination.On T2WI,6 lesions showed slightly higher signal while the remaining 3 lesions showed iso-signal.On T1WI,4 lesions showed slightly lower signal,3 lesions showed iso-signal and 2 lesions showed slightly higher signal while in 1 lesion the local signal showed reduction in anti-phase 1.A central scar was seen in 6 lesions which showed high signal on T2WI,and low signal on T1WI.(3) Enhanced CT: 15 lesions were significantly enhanced and 1 lesion showed mild enhancement at the arterial phase.For the patients with mild enhancement,the scar in the center of the lesion showed no enhancement.In all lesions,the central scar did not enhance.In 5 lesions,enhancements of thickened and torturous arteries were seen.In all the lesions with enhancement,the enhancement was reduced at the portal venous phase,with 12 lesions showing slightly higher density,3 lesions isodensity and 1 lesion low-density.Three lesions showed mild enhancement of the central scar.All the substantial parts of the lesions with enhancement declined at the delay phase,with 3 lesions showing slightly higher density,9 lesions of isodensity and 4 lesions slightly low density.In 7 lesions with central scar delayed enhancement,they showed slightly higher density.Nine patients underwent MRI enhancement and the enhancement characteristics were similar to CT,but the arterial phase magnitude was higher than that of CT.In 4 lesions,the central scar began to enhance at the portal venous phase,while 6 lesions continued to enhance,thus showing slightly higher signal at the delay phase.In a large lesion,there was persistent delayed enhancement in the capsule.(4) On DWI,6 lesions showed inhomogeneous,slightly hyperintensity with the center showing a slit-like low signal area.Three lesions showed iso-signal.The ADC values of the lesions were (1.31±0.08)× 10-3 mm2/s,and the normal liver parenchyma were (1.22± 0.14)× 10-3 mm2/s,(difference not statistically significant).Conclusions CT and MRI using plain and dynamic enhanced scans could show fully and accurately the pathological features and the characteristics of blood supply of FNH.The characteristic signs on both CT and MRI make an accurate diagnosis of FNH.MRI when compared with CT was slightly better.A combined use of both CT and MRI has an important value in the diagnosis of FNH.

Objective To observe the efficacy of de novo combination therapy lamivudine plus adefovir , lamivudine monotherapy and entecavir monotherapy in HBeAg-positive CHB patients with genotype B/C. Methods A total of 182 treatment-naive CHB patients in line with treatment standards of Chinese CHB prevention and treatment guidelines were randomly assigned to three groups and treated with lamivudine plus adefovir or lamivudine monotherapy or entecavir monotherapy for 48 weeks. Results Patients in three groups presented no difference in baseline levels. After treatment by three therapies , the group of lamivudine plus adefovir showed a higher biochemical response rates (12 week P < 0.01, 24 week P < 0.01, 48 week P < 0.01), HBeAg-serological rates(12 week P < 0.01, 24 week P < 0.05, 48 week P < 0.05) and completely virological response rates (12 week P < 0.05, 24 week P < 0.05, 48 week P < 0.05) than lamivudine group. In terms of biochemical response rates , the group of lamivudine plus adefovir had certain advantages when compared with entecavir group. Conclusion De novo combination therapy lamivudine plus adefovir is a good antiviral strategy for chronic hepatitis B patients with B/C genotype viral infection in China.

Objective To summarize the magnetic resonance imaging/ 1 H-magnetic resonance spectroscopy (MRI/1 H-MRS) features of tumor-like inflammatory demyelinating diseases (TIDD),and investigate the clinical value of MRI/1 H-MRS.Methods MRI features of 10 cases of TIDD in brain confirmed by pathology were retrospectively analyzed and compared with pathology.Results The lesions mainly located in the white matter with mild mass effect.MRI scan all showed low T1 high T2 signal,and 7 cases showed high signal,3 cases showed slightly high or mixed signals on DWI.Enhanced MRI showed 5 cases with significant enhancement withopen loop sign,4 cases with significant patchy or nodular enhancement,1 case with mild flakes or linear enhancement.Three cases showed expanded blood vessels and plumbed to the lateral wall inside the edge of the lesions.1H-MRS performance showed 4 cases all with significantly increased Lac and Lip; 3 cases with rised glutamate and glutamine complex β,γ-Glx peaks,reduced N-acetylaspartate acid (NAA),increased Cho to varying degrees.All pathological changes were demyelination,perivascular inflammatory infiltration and reactive gliosis,hypertrophy and abnormal mitotic figure.Seven cases could be seen obesity glial cells.Conclusions TIDD had its salient MRI features:lesion had obvious edema and mild mass effect,MRI enhancement showed open loop sign and small veins expansed,on perfusion-weighted imaging it showed low perfusion.1H-MRS showed β,γ-Glx peaks,Lac and Lip peaks significantly increased,NAA slightly reduced,Cho mildly elevated.Comprehensively analyzing the MRI and 1H-MRS features,combined with clinical manifestations,contribute to the diagnosis of the disease.

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.

OBJECTIVE To study the cardiotoxicity of ophiopogonin D′(OPD′) for rat H9c2 cardio? myocytes. METHODS H9c2 cells were exposed to OPD′ 0.1, 1, 5, 10, 20, 25 and 50 μmol·L-1 for 24 h. Cell viability was examined by MTS assay, and the morphological changes in H9c2 cells were quanti? fied. The cell nucleus injury was examined by high content immune fluorescence screening and the morphological changes were observed under a fluorescence microscope. After treatment with OPD′ 0.1, 1, 5 and 10 μmol·L- 1 for 24 h, the effect on reactive oxygen species (ROS), mitochondrial mem? brane potential(MMP) and apoptosis was detected by flow cytometry. RESULTS The viability was sig? nificantly reduced following exposure to OPD′ 0.1, 1, 5, 10, 20, 25 and 50 μmol·L- 1 (P<0.05,P<0.01). The IC50 value was 9.9 μmol ·L- 1 and cell shrinkage and apoptosis occurred. The levels of ROS and apoptosis rate of H9c2 cells were significantly increased after exposure to OPD′ 0.1, 1, 5 and 10 μmol·L-1 for 24 h (P<0.05,P<0.01) and MMP markedly declined (P<0.05,P<0.01). CONCLUSION OPD′ has significent cytotoxicity on H9c2 cells. It may be related to inducing apopotsis pathways.

The superiority of the cumulative outcomes of day 5/6 embryo transfer to those of day 2/3 embryo transfer in infertile couples has been debated.This retrospective study included data collected from 1051 patients from July 2011 to June 2014.Multiple maternal baseline covariates were subjected to propensity score matching analysis,and each day 5/6 group woman was matched to one day 2/3 group woman.A systematic meta-analysis was conducted to validate the results.After matching was completed,217 patients on the day 2/3 group were matched with those on the day 5/6 group,and no significant differences in the baseline characteristics were observed between the two groups.The cumulative pregnancy rate (57.14％ vs.53.46％,OR 1.16,95％ CI 0.79-1.70) and cumulative live birth rate (53.00％ vs.49.77％,OR 1.14,95％ CI 0.78-1.66) of day 5/6 embryo transfers were higher than those of day 2/3 embryo transfers,but this difference was not significant.The mean cycles per live birth and mean days per live birth in the day 5/6 group were significantly lower than those in the day 2/3 group.This study demonstrated that day 5/6 embryo transfer is a more cost-effective and time-efficient policy than day 2/3 embryo transfer to produce a live baby.

Depression,a common mood disorder,has a complex pathogenesis.In recent years,the accelerated pace of life has been accompanied by an increase in the prevalence rate of depression,leading to extensive attention being given to this condition.External stress and inflammation synergize to damage blood vessel and brain functions,induce immune disorders,cause microglia activation,and increase the expression of pro-inflammatory cytokines and their receptors.Inflammatory reactions continue to escalate,which affects the normal metabolism and metabolism of the neurotransmitter system.The abnormal functioning of molecular pathways leads to mutations in brain cell and nerve genes,and further formation of the immune-inflammation-neuron cycle pathway becomes an important mechanism in the occurrence and development of depression.A large number of studies have shown that traditional Chinese medicines can improve depression symptoms by restoring neuroimmune inflammation homeostasis.This article explains neuroimmune inflammation's close connection with depression and its pathogenesis and reviews the role of various traditional Chinese medical therapies in improving and treating depression by participating in the regulation of neuroimmune inflammation.This review provides new perspectives on the precise treatment of depression and the development of immune-targeted drugs.

Chronic fatigue syndrome(CFS)is a chronic comprehensive disease with a slow course and often accompanied by a variety of physical and psychiatric symptoms.At present,the incidence rate is on the rise.Based on the theory of"qi-pulse smooth and unobstructed",the pathogenesis of CFS is considered to be the loss of spleen and kidney and the deficiency of qi-pulse as the root;liver and lung disorders,qi-pulse stagnation as the pivot;wind fire invasion,phlegm blood stasis as the superficiality.Treatment should focus on tonifying the spleen and tonifying the kidneys to treat its root cause.According to the degree of deficiency of spleen and kidney and the emphasis of deficiency of qi-blood yin-yang,Buzhong Yiqi Decoction,Guipi Decoction,Shengyang Yiwei Decoction,Linggui Zhugan Decoction and Shenqi Pills should be selected flexibly.The methods of soothing the liver and regulating the lungs to regulate their pivot,harmonizing the liver and lungs,and using both ascending and descending functions should be used.Chaihu Shugan Powder,Xiaoyao Powder,Sini Powder,Guizhi Decoction,Shengmai Powder,etc.could be selected flexibly according to the disease location and disease focus.Clearing wind and clearing heat,eliminating phlegm and promoting blood circulation should be used to treat its superficiality,emphasizing tonifying deficiency and resolving depression.According to the different pathogenesis of patients,the corresponding treatment method should be flexibly chosen to supplement with medication.One medical case was attached in this article as the evidence,in order to provide reference for the TCM treatment of CFS.
