Objective To formulate the Psychological Core Diathesis Scale for Military Personnel(Part B),and examine the reliability and validity of the scale.Methods Following the psychometric principles,a five factors model of general cognitive ability was firstly constructed by theoretic analysis.The items of initial scale were then developed,followed by repetitive revision and screening for the final establishment of the Psychological Core Diathesis Scale for Military Personnel(Part B),which was composed of 5subtests and 25 items.One thousand and two hundred healthy soldiers were chosen by randomized cluster sampling to participate in the measurement,and 1143valid questionnaires were analyzed for item analysis,Cronbach'?coefficients,split-half reliability and construct validity.Four weeks later,50out of the 1143soldiers were retested for evaluation of the test-retest reliability.Another 200soldiers were randomly collected for the measurement of Intelligence Test for Military Personnel(Part B)as well as the Psychological Core Diathesis Scale for Military Personnel(Part B).The correlation between the results obtained from the 2scales was then analyzed.Soldiers were comprehensively evaluated by their squad leader according to uniform standard.Finally,the top soldiers and ordinary soldiers(50each)were selected by 20 squad leaders from the 1143valid subjects,the scores of the 2groups of soldiers on Psychological Core Diathesis Scale for Military Personnel(Part B)were then compared.Results Item analysis indicated that the average difficulty index of subtests ranged from 0.44to 0.80,the discriminatory power from 0.31to 0.50,and the test-retest correlation coefficient between total scale and subtests from 0.6253 to 0.9558(P

Objective To investigate the clinicopathological significance of transforming growth factor-β1 (TGF-β1), transforming growth factor-β1 receptor Ⅱ (TGF-βRⅡ ), Smad4 and Smad7 protein expressions in gastric carcinomas. Methods 109 cases of gastric carcinomas,28 of high grade dysplasia,20 of low grade dysplasia,30 of chronic atrophic gastritis,29 of intestinal metaplasia, and 21 of normal gastric mucosa were selected for the detection of the expression level of TGF-β1,TGF-βRⅡ , Smad4 and Smad7 proteins by immunohistochemistry. Results The expression of TGF-β1,TGF-βRⅡ and Smad7 proteins in gastric carcinomas and dysplasia (high and low grade) were significantly higher than those in chronic atrophic gastritis, intestinal metaplasia and normal gastric mucosa (all P <0. 001 ) ,whereas the expression of Smad4 was significantly increased in high and low grade dysplasia (cytoplas-mic IS :4.89±2.38,5.80±1.54, respectively; nuclear IS: 3.89± 1.52,3.80±1.33, respectively), and decreased in gastric carcinomas (cytoplasmic IS:2.41±2.27,nuclear IS:2.02±2. 14) (P <0.001 ,P <0.001 ,respective-ly). Meanwhile,the expressions of TGF-β1,TGF-βRⅡ and Smad7 were higher in advanced gastric cancer (4.36± 2.66,3.05±1.93,4.84±3.06, respectively) than those in early gastric cancer ( 2.93±1.85,2. 17±1.87, 4. 14±2.46, respectively) ( P < 0.01, P < 0.05, P < 0. 05, respectively ) ; however the expression of Smad4 protein was much higher in early gastric cancer (P < 0. 001 ). The expression of Smad4 protein was significantly correlated with tumor size( P < 0.05 ), lymph node metastasis ( P < 0. 001 ), T stage ( P < 0. 001 ) and chnical stage ( P < 0.001) ,and the expressions of TGF-βRⅡ and Smad4 proteins were correlated with patients' 5-year survival rate (P<0.05 ,P < 0.01 ). TGF-β1 showed the positive correlation with TGF-βRⅡ and Smad7 (r1= 0.45 ,P <0. 05; r2 = 0.49, P <0. 05), but negative correlation with Smad4 ( r = - 0.21,P < 0.05 ). Conclusion TGF-β1, TGF-βR Ⅱ, Smad4 and Smad7 protein may play an important role in the carcinogenesis of gastric carcinoma,and smad4 is the key in TGF-β pathway. Also, the detection of these proteins expression can be a useful marker for predicting the gas-tile cancer invasion,metastasis and patients' prognosis.

Chronic inflammatory demyelinating polyneuropathy (CIDP) with positive anti-contactin-associated protein-1 (Caspr1) antibody is a rare autoimmune antibody mediated peripheral neuropathy. A 62-year-old male patient was reported in this article, whose clinical manifestations were subacute onset, abnormal distal limb motor sensation, and increased cerebrospinal fluid protein level. The patient had a good response to plasma exchange. Electromyography of lower limbs showed that motor involvement was dominant, motor conduction velocity slowed down, compound motor active potential (CMAP) and sensory nerve active potential amplitude decreased, and F wave was not elicited; electromyography of upper limbs without symptoms showed that CMAP amplitude of median nerve decreased, and conduction velocity was normal. There are few reports of anti-Caspr1 positive CIDP in the world. The article summarized the characteristics of the patient and reviewed the relevant literature, in order to improve clinicians′ understanding and diagnosis and treatment ability of the disease.

Cell-to-cell communication is a fascinating process that is essential for maintaining tissue and whole-body homeostasis.Extracellular vesicles(EVs)are cell-derived membrane-bound nanoparticles that are a means of communication between cells.Accumulating evidence indicates that EVs can render either beneficial or harmful outcomes,depending on the specific cargos(e.g.,proteins,lipids,RNAs)transferred between cells.EVs also have great value as diagnostic and prognostic markers of disease because they are present in a variety of biological fluids and carry bioactive molecules from their cells or tissues of origin.Liver cells can both release and receive EVs derived from other cells and emerging evidence indicates that liver EVs play important roles in the pathogenesis of various liver diseases,including liver cancer,viral hepatitis,non-alcoholic fatty liver disease,and alcoholic liver disease.This review provides an overview of the biogenesis and secretion of EVs and summarizes the most recent advances in understanding the role of EVs in liver physiology and diseases.Additionally,we discuss potential applications of liver EVs as biomarkers and in therapeutic approaches to treat liver diseases.

Objective To investigate the relationship between the anti-earthquake military rescuers' psychosomatic health and social support, and observe the effect of intervention to the army men who suffered troubles.Methods By cluster random sampling, 152 military rescuers and 139 army men not taking part in the rescues were investigated by Facility Psychosomatic Health Scale and Social Support Rating Scale. Mental intervention or medication was performed to those produced psychosomatic health. Results The scores of somatic symptoms,mental status,psychosomatic health and social support of military rescuers and the control group were (4.09±4.70) ,(2.18 ±3.16) ,(6.27 ±7.08) ,(6.14 ±4.20) and (2.11 ±4.16) ,(1.37 ±3.09),(3.47 ±6.55),(4.57 ± 4.17 )respectively, the difference was significant(P＜0.05). The somatic symptoms had significantly positive correlation with mental status in military rescuers (r=0.17～0.52, P＜ 0.05 or 0.01 ). Failure of social support had positive correlation with mental disorders (r=0.18～0.40, P＜0.05 or 0.01). The degree of social support was the main factor which had affected on the psychosomatic health of military rescuers. The somatic symptoms of military rescuers were apparently higher than their mental symptoms. Mental and pharmaceutical intervention showed good effect on them. Conclusion There is an apparent effect for military rescuers injured seriously psychosomatic health through medication or mental intervention.
