The operation signature regulation in force in China means giving the right of signature agreeing to the operation to a third party including the patients family. This kind of practice not only goes against the principle of informed consent and relevant regulations as stipulated in the General Rules of the Civil Law of the Peoples Republic of China and the Contract Law of the Peoples Republic of China, but is also likely to cause medical disputes. For this reason, the signatory right agreeing to the operation ought to belong to the patient himself unless it is a legal matter.

Objective To study the cautious behaviors of mice under dangerous conditions caused by height. Methods An elevated beard task was designed,in which the mice were employed to get through a horizontally elevated beard. The time of getting through and number of looking-aside behaviors were recorded under different experimental conditions with different elevated height and visual cues. Results The mean time of getting through the elevated board with a height of 60cm was significantly longer than that of 15cm [(22.55±14.64)s Vs (12.16±8.67)s, P<0.05]. The number of looking-aside behaviors decreased from (2.95±1.73) to (1.95± 1.27) , P <0.05 ,when the visual cues on potential danger were controlled. Conclusion The cautious behaviors increase with the height of elevated board and decrease when controlling for the visual cues on potential danger, which indicate a trade-off relationship between the perceived danger and cautious behaviors.

Objective To investigate the ability of theory of mind use in elders,and determine the role of inhibitory control in the use of theory of mind. Methods The participants included 30 young-old people ,30 oldold people and 30 young people. Their ability of theory of mind use and inhibitory control were examined with The Referential Communication Task and Hayling Sentence Completion Test,respectively. Results The correct rate of referential communication task was significantly lower in old-old people (0.43 ± 0.32) than those of young-old people (0.69 ±0.24, P=0. 001 ) and young people (0. 77 ±0. 25, P＜0. 001 ). Partial correlation analysis showed that the total errors in Hayling Test-B was negatively correlated with the correct rate of Referential Communication Task ( r= -0.442, P＜0.001 ). Hiberarchy regression analysis showed that the total errors in Hayling Test-B entered the equation ( β = -0.451, P＜0. 001 ) and could independently explained 16.8% of the variance (△R2 = 0. 168, △F = 19.359, P ＜ 0.001 ) after controlling for age. Conclusion Old-old people show worse performance in the use of theory of mind. The impairment of inhibitory control can partly explain the decline of theory of mind use in old-old people.

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

Objective: Exploring the developmental vitial moments and process of career identity.Methods: A case subject was administered structured interview and tested by Career Identity and the Related Factors Questionnaire,Chinese Self-Efficacy Scale,QZPS and MBTI-G.Results: There were several vital moments in the process of career identity,such as the first time to think about career identity,and select a major,the first time to choose career and get employed,meet the organizational changes,find a new job again and get promotion.The present crisis of career identity reflected some unresolved problems of previous developmental periods.Conclusion: The individual's objective behavior toward career choice,decision-making,continuous exploration and efforts were of great benefit to career identity.

Objective:To test the validity and reliability of BSRI (Bem Sex Role Inventory) in Chinese culture Method:340 undergraduates from three universities in two cities were collected as the subjects They all completed the BSRI Item analysis and factor analysis were done followed by item revision making the inventory more suitable to Chinese culture Result:The new brief scale was composed of 14 masculine items and 12 feminine items The reliability and validity were improved after the revision Conclusion:The new brief scale is more suitable to Chinese culture

Objective:To investigate an effective paradigm to test false belief understanding for the Autism. Method:By comparing the multimedia animation presentation and the traditional presentation, 20 autistic children's false belief understanding was analyzed as well as the normal children's.Results:Animation presentation was really helpful to both groups, especially for the children with autism. The performance might be underestimated due to the application of the traditional presentation in false belief tasks.Conclusion:The autistic children's theory of mind can be measured much closer to the truth if the more apt tasks are considered.

Objective:To examine the clinical experience and efficacy of unrelated cord blood transplantation (UCBT) in the treatment of recurrent refractory Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH) in children.Methods:The clinical data of a patient with recurrent refractory EBV-HLH and intestinal perforation who was treated by UCBT in Department of Pediatrics, the First Affiliated Hospital of Zhengzhou University in September 2015 and finally cured were retrospectively analyzed.Meanwhile, literature was reviewed.Results:The patient, male, 1 year and 6 months, was admitted to the hospital with " fever for 15 days, rash for 9 days" as the main complaint, mainly manifested as high fever, large liver, spleen, lymph nodes, rapidly progressing pancytopenia, liver function damage, phagocytic blood cells on bone marrow smear, diagnosed as EBV-HLH in September 2015.The patient received chemotherapy according to the HLH-2004 protocol developed by the International Association of Cell Societies.During the treatment, he suffered two recurrence during the maintenance period, and a second-line rescue treatment was adopted, namely, " Pegaspargase, Doxorubicin liposome, Etoposide and Methylprednisolone" (L-DEP regimen) chemotherapy.The complete relief of diagnostic indexes for hemophagocytic lymphohistiocytosis was evaluated after chemotherapy.The patient developed sudden intestinal perforation and underwent emergency surgical surgery, enteroenterostomy.After the condition was stabilized, the patient was pretreated with the " Fludarabine+ Busulfan+ Cyclophosphamide" (Flu+ BU+ CY) therapy and then treated with UCBT, with intravenous nutritional support provided during the entire process.Neutrophil and platelet implantation was implemented on day 13 and day 35 after transplantation, respectively.The chimeric rate was 100%, and the implantation was a success.Hepatic veno-occlusive disease, fungal pneumonia and skin graft-versus-host disease (GVHD) Ⅱ occurred on the 15 th day, 22 nd day and 26 th day after transplantation, respectively.The corresponding symptoms improved after treatment.On day 49 after transplantation, phase Ⅱ " enterostomy fistula" was performed.The patient was followed up to 70 months after transplantation, and generally in good condition.His symptoms relieved, and no chronic GVHD and other comorbidities occurred. Conclusions:Allogeneic hematopoietic stem cell transplantation is the only possible effective means of treating relapsed refractory EBV-HLH in children.In the absence of a suitable sibling or unrelated donor, unrelated cord blood stem cells can be used as a graft source.Enterostomy after intestinal perforation is not contraindicated for transplantation.

Objective:To analyse the differences of related genes between serum alpha-fetoprotein (AFP) positive gastric cancer and AFP negative gastric cancer, and the relationship between related genes and prognosis of serum AFP positive gastric cancer.Methods:A total of 1 144 gastric cancer patients undergoing surgery at the 940th Hospital , Joint Logistic Support Force, People's Liberation Army from Jan 2013 to Dec 2018 were retrospectively analyzed. Of them, 47 cases were of AFP positive gastric cancer, and 47 serum AFP negative case were obtained by proper matching method.Results:Forty-seven patients with serum AFP positive gastric cancer, accounting for 4.1% of all gastric cancer patients during the same period. The prognosis of serum AFP negative gastric cancer is better than that of serum AFP positive gastric cancer. The 1-, 3- and 5-year cumulative survival rates were 95.6% vs. 63.8%, 48.9% vs. 23.4% and 26.7% vs. 14.9%, respectively. There were statistical differences in the immunohistochemistry of AFP, HER2, VEGF, GPC3, SALL4, P53 and Ki67 between the two groups ( χ2=67.758, P<0.001; χ2=4.004, P=0.044; χ2=19.299, P<0.001; χ2=5.232, P=0.022; χ2=6.359, P=0.012; χ2=6.224, P=0.013; χ2=5.232, P=0.022). The more co-positive expressions of AFP, GPC3, VEGF and SALL4, the more likely they were to affect pTNM stage, vascular invasion and liver metastasis ( χ2=5.328, P=0.021; P=0.013; χ2=5.887, P=0.015; χ2=3.923, P=0.048). Univariate and multivariate survival analysis of serum AFP positive gastric cancer showed:AFP, GPC3, VEGF and SALL4 were risk factors for AFP positive gastric cancer ( HR=3.700, P=0.036; HR=4.237, P=0.003; HR=3.916, P=0.004; HR=3.412, P=0.001). Conclusions:Serum AFP positive gastric cancer is a rare and highly invasive special type of gastric cancer. AFP, GPC3, VEGF and SALL4 are overexpressed in serum AFP positive gastric cancer, which is correlated with tumor stage, vascular invasion and liver metastasis. The final diagnosis of serum AFP positive gastric cancer still needs immunohistochemical examination. Preoperative serum AFP level is an important basis for AFP positive gastric cancer screening and AFP immunohistochemical examination.
