Objective: To explore the feature of theory of mind(ToM) in schizophrenic patients and the influencing factors. Methods: Subjects were 108 patients with schizophrenia, 21 with affective disorders and 21 normal subjects. Picture-story tasks, PANSS and WAIS-R were used to assess the patients' ToM, symptoms and intelligence. Results:It was found that the scores on first-order theory of mind tasks of schizophrenic patients with IQ below 70 were lower than normal subjects'(D = -56.58,P

Functional experiment is an important course to cultivate medical undergraduates'comprehensive and creative thinking abilities. Based on the conduction of the course, prominent teaching factors like the qualifies of teachers and students, the making of the courseware, the choosing of experiment contents and the arrangement of teaching progress,have been analyzed and practical teaching suggestions have also been proposed for a better functional experiment bilingual teaching quality.

BACKGROUND:During the research of ABO blood type antigen, the overwhelming majority samples of same ABO gene express a normal and same ABH antigen. But a certain amount samples with the same ABO genetic background show different antigen intensity expression as for different family or individuals. The ABO blood type has complex expression regulation mechanism. Analysis of ABO blood group serology and genetic background of these rare bi-specific AB phenotype specimens, and further studying on epigenetics may partly revealed ABO gene expression mechanism. OBJECTIVE:To study methylation of CpG island and explore the relationship between ABO gene promoter coding glycosyltransferase with dual donor specificity and ABH antigen expression. METHODS:Six samples detected as CisAB or B(A) phenotype were studied in this paper. The whole code sequences and promoter sequence of ABO gene were amplified respectively. The level of CpG methylation in promoter of ABO gene was further detected with bisulfite treatment method. RESULTS AND CONCLUSION:Among the six bi-specific AB phenotype samples, two previously-identified CisAB05/B(A)06 al eles with nt803C>G on the basis of B101 al ele sequence could be seen, and three additional methylated sites nt-33(30%), nt+27(50%) and nt+49(50%) were found between the two regions of CpG island in promoter of ABO gene. Two CisAB01 al eles with nt803C>G mutation on the basis of A101 sequence were found at nt-26C(10%). Other two B(A)04 al eles contained nt640A>G mutation on the basis of B101 sequence were found in the whole code sequences regions, and six additional methylated sites nt-33(10%), nt+16(50%), nt+57(60%), nt+59(60%), nt+68(60%) and nt+74(60%) were found between the two samples. No abnormity was identified in the promoter region of ABO gene. Our results indicated that the differential methylation levels in the CpG island of ABO gene promoter region may affect ABH antigens expression on the red cel membrane even if the samples had the same ABO genetic background.

The electrohydraulic impulse water treatment equipment is developed to purify the drinking water and treat with the wastewater from industry production and living.Taken as the negative electrode,the air jet nozzle can input the air or oxygen into the working chamber,and thus the equipment is turned into a generator of low-temperature plasma ozone and its sterilization effect is vastly enhanced.According to experimentations and references,the factors that influence the erosion of electrode are discussed in detail in this paper.The metal ions in water have to be limited during the electrohydraulic impulse sterilization,or the sterilization effect will be weaken.

Objective To study the related factors of postpartum depression (PPD) and the effects of intervening measures to PPD incidence. Methods 1 597 pregnant women selected from our antenatal care clinic were investigated by using the hospital anxiety and depression questionnaire (HAD) during pregnancy and the Edinburgh postpartum depression scale (EPDS) after childbirth.All the enrolled women were randomlyd divided into control group and intervening group by the proportion of 1 to 2.Six intervening measures were used in the latter group. Results (1) There were 49 women whose HAD≥11 score (anxiety-depression mood)with 28 cases (57.1%) had got postpartum depression in the control group.In the intervening group,however,there were 94 women whose HAD≥11 score with 24 cases (25.5%) had got postpartum depression.There is a significant difference between the two groups ( P

As the development of international education in our school,concern with the culture shock,which caused by the differences cultural background,is increasing.We talk about our feelings of how to solve the culture shock by summarizing the culture shock and its manifestation for exploration of further improving our management level and teaching work.

Objective To analyze the reasons of catheter fracture of implantable vascular access devices and to explore the prevention and handling measures. Methods A retrospective analysis was carried in 3 887 adult patients with implantable vascular access devices and 13 had catheter fracture. The clinical features and causes were analyzed and the successful handling measures were summarized. Results Of 3 887 cases, a total of 13 (0.33%) catheter fracture occurred. The incidence rate of catheter fracture via subclavian jugular venipuncture was 3.70%,(6/162) , via internal jugular venipuncture was 0.18% (7/3 725), via internal jugular venipuncture was significantly lower than that via the subclavian venipuncture (χ2=47.505,P=0.000). There had no statistical differences between the left and right of the two puncture ways(P=0.707,0.682). Conclusions Catheter fracture is one of the serious complications in the process of use and maintenance of implantable vascular access device. Choosing appropriate surgical method, strengthen maintenance education, specificating the operation procedure, closing observation and other measures can not only reduce the occurrence of the catheter fracture, but also can dealt with catheter fracture in time, which could ensure the safety of patients' life.

Objective To analyze the characteristic colligation force vector curves in hemiplegic patients. Methods Eleven hemiplegic patients were recruited, and 11 healthy elderly served as control. The characteristic changes of the patients with regard to colligation force vector demonstrated on a feedback apparatus of the "X.O.S"system during the dynamic training exercise program were analyzed and compared with that of the control group. Results The value of the colligation force vector passing most of the regions were significantly decreased ( P

Primary hepatic lymphoma (PHL) is an extremely rare disease without any unified diagnostic criterion.The symptoms are usually nonspecific.Liver biopsy remains the most valuable tool for diagnosis of PHL.The predominant histology of PHL is diffuse large B-cell lymphoma.The therapeutic modalities are variable,including surgery,chemotherapy,radiotherapy,or combination of the various processes.This article described a 33-year-old man with diffuse large B-cell PHL who was treated at the Affiliated Cancer Hospital of Shanxi Medical Univeitity Blood Disease Diagnosis and Treatment Center in February 2014.The patient benefited from eight-cycle chemotherapy.At present,the patient is disease-free and undergoes regular follow-up.

Objective To study the clinical characteristics and treatment of primary nasal B-cell lymphoma (PNBCL). Methods A retrospective analysis was performed based on the clinical records of 18 PNBCL cases who were treated from January 2009 to June 2015. The clinical manifestations, imaging features, diagnosis approaches and treatment of them were analyzed. Results The main symptoms were nasal obstruction and rhinorrhea. Of all patients, 15 cases were in Ann Arbor stageⅠE-ⅡE, and 3 cases were in Ann Arbor stageⅢE-Ⅳ. The median age was 51 years (12-76 years). The ratio of men to women was 11:7. Only 1 patient had B symptoms. Elevated LDH levels were observed in 4 patients. 13 patients were diffuse large B-cell lymphoma(DLBCL), 3 patients were mantle cell lymphoma, and 2 patients were Burkitt lymphoma. CT examination showed the abnormal nasal soft tissue shadow, with unilateral location and light to moderate enhancement. 14 patients received combination chemotherapy only, and 3 patients received chemotherapy and radiotherapy. Total effective rate was 82.3 % (14/17). At the time of last follow-up, 5 patients died, and the 3-year OS rate was 54.5%(6/11). Conclusions Most PNBCL patients are in Ann Arbor stageⅠE-ⅡE and B symptoms are rare, and the most common pathological types is DLBCL. The treatment for PNBCL is chemotherapy, radiotherapy can assist, but the prognosis is poor, and innovative chemotherapy regimens are necessary.
