ABSTRACT
Endometrial carcinoma (EC) is one of the most common gynecologic tumors, and its incidence and mortality are increasing.The prognosis is usually favorable when the disease is diagnosed at an early stage. However, the prognosis for patients with recurrence and metastasis is relatively poor. As one of the risk factors for EC, the complex and widespread oncogenic role of obesity in EC has been validated, then the oncogenic and pro-carcinogenic mechanisms of adipocytokines secreted by adipose tissue in EC have attracted continuous attention. This review highly summarizes and concludes the previous relevant literature on the role of adipocytokines in endometrial cancer and the progress of research，and elucidates the correlation between adipocytokines and the occurrence risk, stage grading, and long-term prognosis of EC, as well as their signaling pathways and mechanisms of action in the development of EC. All this information will likely contribute to the development of novel molecular markers in EC, the discovery of new therapeutic targets, and the study of related targeted drugs, which may in turn break the current dilemma of early screening, early diagnosis, and treatment of recurrent and metastatic patients in EC in the future, resulting in an improvement of the long-term prognosis of patients with EC.
ABSTRACT
To improve the remediation efficiency of plants on low concentration uranium-bearing wastewater and clarify its strengthening mechanism, Syngonium podophyllum-Peperomia tetraphylla co-planting system was established, the enhanced effects of plants interaction on uranium removal were investigated, the chemical forms, valence states, and subcellular distribution of uranium in plants were confirmed, and the mechanisms of alleviating uranium stress by plants interaction were revealed. In Syngonium podophyllum-Peperomia tetraphylla co-planting system, the total amount of ethanol-extracted uranium and deionized water-extracted uranium with higher toxicity in their roots were reduced by 10.30% and 7.17%, respectively, which reduced the toxicity of uranium to plants. Plants interaction can inhibit the reduction of U(VI) in the root of Peperomia tetraphylla, which is conducive to the transport of uranium from roots to shoots. In addition, uranium in plants mainly existed in the cell wall (54.44%-66.52%) and the soluble fraction (23.85%-32.89%). These results indicated that Syngonium podophyllum and Peperomia tetraphylla co-planting can enhance their effects of uranium removal by alleviating uranium stress with the cell wall immobilization and vacuole compartmentation, improving biomass of plants, increasing bioaccumulation factor and translocation factor of uranium.

Objective@#To explore the relationship between HCM pathogenic gene mutations and clinical phenotypes by analyzing the prenatal diagnosis and genetic characteristics of a pregnant woman from a family with hypertrophic cardiomyopathy (HCM). @*Methods@#The clinical data of the proband and her family members was collected. The DNA was extracted from the peripheral blood, amniotic fluid cells and cultured amniotic fluid cells of proband. Next generation sequencing (NGS) was utilized for screening pathogenetic loci of the proband. The suspected mutation sequences of HCM pathogenic candidate genes MYH7 and MYBPC3 were directly sequenced after PCR. Pathogenicity prediction of amniotic fluid cells was performed by using genetic data and bioinformatics software, such as Mutation taster, PolyPhen-2 and ANTHEPROT. @*Results@#The sequencing results showed that heterozygous mutations of MYH7 c.1988G＞A (p.Arg663His) and MYBPC3 c.151G＞A (p.Ala51Thr) were found in the proband. The phenotype of her father was normal, and no abnormal mutations were detectable. Her mother also showed normal phenotype but carried MYBPC3 c.151G＞A heterozygous mutation. Only MYH7 c.1988G＞A heterozygous mutation was found in the fetus and no abnormal variation of MYBPC3 was showed. The prediction of mutation effect and analysis of protein structure and function revealed that the two missense mutations could affect the hydrophobicity and antigenicity of the protein. The genetic data demonstrated MYH7 c.1988G＞A was defined as a pathogenic mutation. @*Conclusion@#MYH7 c.1988G＞A should be a newly generated pathogenic mutation in the proband, or caused by reproductive chimerism of her parents. MYBPC3 c.151G＞A mutation may promote the occurrence of HCM. Although the fetus only carries MYH7 c.1988G＞A, her phenotype may still display as HCM.
ABSTRACT
The present study examined the relationship between difficulty in re-entry adjustment and job embeddedness, considering the mediating role of sense of professional identity. The online data on demographic characteristics, difficulty on re-entry adjustment, sense of professional identity, and job embeddedness were collected from 178 Indonesian returnees from multiple organizations. The results showed that difficulty in re-entry adjustment was a significant predictor of a sense of professional identity; a sense of professional identity was a significant predictor of job embeddedness. Furthermore, sense of professional identity is an effective mediating variable, bridging the relationship between post-return conditions to the home country and work atmosphere. Finally, the key finding of this study was that sense of professional identity mediated the effect of difficulty in re-entry adjustment on job embeddedness. The theoretical and practical implications, study limitations, and future research needs of our findings are noted.
ABSTRACT
Objective To Analysis the physical fitness participation of 1243 community residents and to provide the scientific basis for developing intervention strategies. Methods The study was based on data of Physical Activity Questionnaire collected in Nutrition and Health Survey 2006 in Putuo, Shanghai. 1 243 subjects aged 6 years and above were involved. Results 43.8% of community residents had participated in physical exercise. Participation ratio was 41.4% in male, lower than that in female (45.8%). Participation ratios among aged 6yr～, 18yr～, 45yr～, 60yr～ were 48.1%, 25.2%, 22.0%, 64.9% in male and 40.8%, 22.5%, 40.1%, 67.1% in female. Participation ratios among age groups were significantly different (P=0.000). Proportion for frequent exercise of all age groups were 25.0%, 11.9%, 19.7%, 64.9% for male and 21.1%, 15.0%, 37.4%, 66.3% for female. There were difference among age groups (P= 0.000). Conclusion Specific intervention measures should be developed for different kind of people.
ABSTRACT
Objective To explore the neural basis of the visual illusory motion using the event-related potential(ERP).Methods One hundred trials(each duration 2 000 ms)of a visual illusory motion figure,rippling wheat pattern made by Akiyoshi Kitaoka,and a visual static figure made of modified rippling wheat pattern were randomly presented with equal probability.Ten healthy right handed undergraduate students as subjects were asked to judge the stimulus whether motional or not.The EEG was recorded from 128 scalp sites using with electrodes mounted in HydroCel GSN cap(Electrical Geodesics Incorporated,Oregon,USA).Results 1)The C1 component of ERP could be evoked by both visual illusory motion pattern and static pattern in POz.The peak of C1 component was presented about 75 ms after each stimulus.C1 component evoked with visual illusory motion was negative,but it's static pattern to be positive.2)P100 and P200 components could be obviously evoked by both kinds of stimuli,but in O2 the amplitudes of P100 evoked by different stimuli were significant different and in T3 the amplitudes of P200 were significant different too.Conclusion The visual illusory motion is formed at the primary visual cortex.It may be related to the organized mode of perception.

ABSTRACT
Objective:To investigate the relationship among college student’s depression symptoms, problem solving appraisal and perceived stress.Methods:275 college students completed questionnaires, including CES-D, Chinese Perceived Stress Scale (CPSS) and Chinese Problem Solving Inventory (CPSI). Results: Among these students, 52% reported on the level of health risk stress (HRS), 55.3% had depression symptoms. There were significant correlation among depression symptoms, perceived stress and problem solving appraisal. The causal relationship between them were identified with the path analysis method, problem solving in special, seems to have both direct and indirect effect on the prediction of depression and on perceived stress. Conclusion:There is a high level of college student perceived stress and depression symptoms. Problem solving appraisal is an important factor for both of them.
