Objective To explore the childhood abuse impact on clinical and personality characters among anxiety associated depressive patients.Methods A case-control method was taken among 86 anxiety associated depression patients,36 cases with childhood abuse and controlled with 50 cases without childhood abuse.HAMD,HAMA,CECA-Q,MMPI were used to evaluate the participants,and the scores of the results were compared between the two groups.Results For the HAND,the group with CA were significantly higher than the group without CA(t=7.079,P＜0.05).From the point of factor scores,there was not a significant difference between the two groups among the factors such as anxiety somatization,cognitive impairment,and hopelessness.From the point of view of the total scores of HAMA (t=3.108) and spiritual anxiety (t=4.037),somatic anxiety (t=2.742) the CA group was significantly higher than group without CA(P＜0.05).In the patients with CA the psychoticism(P) (t=2.794) and neuroticism (N) (t=3.217) factors were significantly higher than patients without CA (P＜0.05).MMPI evaluation results showed accept ance T points in addition to lie(L),calibration(K),male woman(Mf),light mania(Ma),the CA group were significantly higher than the group without CA(P＜0.05).T points to compare two groups of MMPI additional factor scale,the adaptation to the society (A),emotional intelligence (EQ),decisionmaking ability (DE),CA group were lower than the group without CA,violence (VL),traffic accident (DR) and addiction(SA) with CA group was higher than the group without CA(P＜0.05).The regression analysis showed that the emotional neglect score and HAMD scores were positively related in the relationship of the childhood abuse and depression.Y =3.729+0.887 X(P=0.000).Sexual abuse score and HAND scores were related,regression analysis showed that the Y =9.799 + 0.655 X (P =0.000).Conclusions The clinical patients with CA have more severe symptoms than the patients without CA.Personality is extraversion more emotionally unstable.Their emotional intelligence and decision-making comprehensive ability is low,and violence tendency is obvious.Emotional neglect and sexual abuse have an important impact in the pathogenesis of the disease.

Integrating medical instruments with medical information systems becomes more and more important in healthcare industry. To make medical instruments without standard communication interface possess the capability of interoperating and sharing information with medical information systems, we developed a medical instrument integration gateway based on Integrating the Healthcare Enterprise Patient Care Device (IHE PCD) integration profiles in this research. The core component is an integration engine which is implemented according to integration profiles and Health Level Seven (HL7) messages defined in IHE PCD. Working with instrument specific Javascripts, the engine transforms medical instrument data into HL7 ORU message. This research enables medical instruments to interoperate and exchange medical data with information systems in a standardized way, and is valuable for medical instrument integration, especially for traditional instruments.

Objective To investigate the effect of magnifying endoscopy with narrow-band imaging (ME-NBI) in diagnosis of early gastric neoplastic lesion. Methods 151 patients with suspected gastric cancer underwent endoscopic examination in digestive endoscopy center from January 2013 to June 2016 were enrolled the study. They firstly received conventional white light endoscopy (WLE), then ME-NBI (including intervening part) and targeted biopsy. And all patients were divided into early cancer group (high grade intraepithelial neoplasia, intramucosal carcinoma and submucosal carcinoma, n = 72) and non-early cancer group (low grade intraepithelial neoplasia, n = 79). The area under receiver-operating characteristic curve (AUC) was performed to evaluate prognostic value of each index in early cancer. Results The incidences of the demarcation line, irregular microvascular pattern, irregular microsurface pattern and increasing intervening part in early cancer group were significantly higher than that in the non-early cancer group (P < 0.05). The AUC of ME-NBI for early gastric cancer was 0.947 and higher than 0.832 of WLE. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and Youden index were 97.2%, 84.8%, 85.4%, 97.1% and 0.820, respectively. The AUC of intervening part for early gastric cancer was 0.907 and higher than 0.889 of the traditional VS classification, and AUC, sensitivity, specificity, PPV, NPV and Youden index of VS type combined with intervening part were 0.933, 95.8%, 83.5%, 84.1%, 95.7% and 0.794, respectively. Conclusions ME-NBI is an important method for diagnosis of early gastric cancer, and intervening part has the advantages of strong objectivity, simple and easy to operate, good repeatability, and it could be used to assist traditional VS classification in judging the nature of lesions.

Objective To identify the role of the IKK / NF-kappa B signaling pathways in the acquisition and consolidation of extinction memory in conditioning fear.Methods Aduh SD rats were treated with nuclei buried surgery.After a week recovery from nuclei buried surgery,adult SD rats accepted auditory fear conditioning training.Before the extinction training,bilateral intra-BLA infusion of sulfasalazine(SSZ),an inhibitor of IKK/NFκ B,and Vehicle were done.The freezing time were tested on the 24h and 1w after the extinction.Results After training,all the rats showed higher percentage of freezing time than the baseline(Vehicle:pre-CS 21.16％,post-CS 71.23％,P＜0.01 ; SSZ:pre-CS 22.23％,post-CS 72.14％,P＜0.01).The percentage of freezing time had no significant difference(SSZ 47.52％,Vehicle 46.20％,P＞0.05)between Vehicle and SSZ at the end of extinction training.However,SSZ groups showed significantly higher percentage of freezing time than the control group on the 24h(Vehicle 41.03％,SSZ 60.51％,P＜0.01) and the same was found on 1 weck test(Vehicle 34.17％,SSZ 57.21％,P＜ 0.01).The rats injection with SSZ showed significant fear response for the auditory fear condition.Conclusion All above results suggest that interference of IKK/NF-κ B signaling pathway impaire the consolida tion but have no effect on the acquisition of fear extinction memory in conditioning fear.The available date could provide us some clinical guidance in the treatment of post-traumatic stress disorder and panic disorder.

ObjectiveTo identify the effects of venlafaxiue on the acquisition and consolidation of fear extinction memory in conditioning fear memory extinction model.MethodsMale Sprague-Dawley rats were treated with fear conditioning training in the A environment.Before the extinction training,all the experimental rats were given different doses of venlafaxine intraperitoneal injection.After 24 hours,all the rats test in the B environment.ResultsRepeated-measures ANOVA were conducted on the percent of freezing time for between-session extinction,test condition (F2,44 =458.958,P＜0.001 ) and VEN dose(F2,22 =43.026,P＜0.001 ) and a Test condition * Treatment interaction (F4,44 =31.363,P ＜ 0.001 ).For the within-session,post hoc comparisons indicated that the three groups that received different dose of VEN (0,20 and 40 mg/kg) did not differ from each other (P ＞ 0.05 ),indicating similar extinction following the post-conditioning.The rats injected with high-dose venlafaxine (40 mg/kg) intraperitoneally before extinction training showed pro,motion of between-subjects extinction of fear memory,but does not affect the within-subjects extinction.There was no significant catabolism in the rats injected with middle-dose (20 mg/kg).ConclusionThe available date indicate that venlafaxine could promote the extinction of fear memory and there is a dose-dependent relationship of venlafaxine in the facilitation of fear memory.Our results could provide some clinical guidance for the treatment of post-traumatic stress disorder and panic disorder.

Objective To investigate the expressions of advanced glycosylation end products (AGE) in skin of mice with diabetes mellitus (DM) for different durations,and to evaluate their influence on collagen fibers.Methods Forty healthy 8-week-old male C57BL/6J mice were divided into DM group (n =20) and control group (n =20) to receive multiple intraperitoneal injections of low dose streptozotocin (50 mg/kg) and citric acid buffer (0.1 mol/L),respectively,for 5 consecutive days.Ten mice were sacrificed in each group on week 4 and 12 respectively after the last intraperitoneal injection,and full-thickness skin tissue samples were harvested from the middorsal region of each mouse.Then,hematoxylin-eosin (HE) staining was performed to observe histological changes,and total collagen content was estimated according to hydroxyproline content measured by an alkalinehydrolysis method.The cross-linking degree of collagen was determined by Edman degradation method using pepsin,the mRNA expression level of collagen type Ⅰ and Ⅲ by real-time quantitative PCR,the content of AGE by fluorospectrophotometry and Western blotting,and the level of malondialdehyde (MDA) by using a thiobarbituric acid method.Statistical analysis was carried out by t test.Results As light microscopy showed,the skin became obviously thinner in the diabetic mice with a progressive decrease in the number of collagen fibers in comparison with the control mice.On week 4 and 12 after the last injection,the diabetic mice exhibited a significant reduction in the content of hydroxyproline ((684.5 ± 76.7) vs.(787.7 ± 87.7) rg/g,(558.1 ± 73.1) vs.(757.8 ± 75.3) mg/g,both P ＜ 0.01) and in the levels of cross-linked collagen as well as mRNA expressions of collagen Ⅰ and Ⅲ (P ＜ 0.01 or 0.05),but a significant increase in the content of AGE ((37.47 ± 10.65) vs.(26.39 ± 3.74) AUF/mg hydroxyproline,(47.70 ± 5.66) vs.(29.91 ± 6.50) AUF/mg hydroxyproline,both P ＜ 0.01) and MDA ((6.62 ± 0.47) vs.(4.82 ± 0.56) μmol/L,(8.63 ± 0.36) vs.(5.15 ± 0.46) μmol/L,both P＜ 0.01) in skin tissue,compared with the control mice.The level of non-cross-linked collagen in skin tissue was also lower in the diabetic mice than in the control mice on week 12 (P ＜ 0.05).Moreover,the contents of hydroxyproline and the expression levels of collagen I in skin were significantly lower (P ＜ 0.05),but the levels of AGE and MDA were significantly higher (P ＜ 0.01) in the diabetic mice on week 12 than in those on week 4.Conclusions The characteristics of collagen fibers in skin are altered in diabetic mice when compared with normal control mice,which may be associated with increased AGE content and oxidative injury in skin.
