RESUMO
Objective:To analyze the relationship between the expression and prognosis of kinesin family member 4A (KIF4A) in renal clear cell carcinoma and explore its potential mechanism.Methods:Information on the KIF4A gene in renal clear cell carcinoma was retrieved from the UALCAN database, including expression levels, survival analysis, and positive and negative correlation gene data, from which the expression levels, prognostic information, and potential mechanisms of KIF4A in renal clear cell carcinoma were derived.Results:KIF4A is highly expressed in renal clear cell carcinoma, and male patients have a higher expression rate than female patients. The higher the tumor grade and the later the N stage, the more expression ( P<0.05). The survival analysis showed that the expression level and prognosis of KIF4A were negatively correlated ( P<0.05). Cyclin B2 (CCNB2), kinesin family member 23 (KIF23), cell division cycle associated 5 (CDCA5), and KIF4A were significantly positively correlated, whereas DHRS12, crumbs protein homolog 3 (CRB3), β-hydroxybutyrate dehydrogenase 2 (BDH2), and KIF4A were significantly negatively correlated. Conclusions:KIF4A plays an important role in the development of renal clear cell carcinoma and can be used as a potential marker and therapeutic target for the diagnosis and prognosis of renal clear cell carcinoma, including in children.
RESUMO
Background Because of high working intensity, high responsibility, and unexpected situations, health care workers may suffer great work pressure, which may lead to health damage. Objective To explore the self-rated health status and its influencing factors such as demographic and occupational-related factors of medical staff in Lanzhou. Methods In-service medical staff were selected by using cluster random sampling method from 18 public hospitals in Lanzhou City and were investigated with a self-made questionnaire and the Self-rated Health Measurement Scale (SRHMS). SRHMS includes 48 items in 10 dimensions, which are divided into three sub-scales of physical health, mental health, and social health, and another independent dimension is overall health. The scores were converted into a percentage scale and expressed as the percentage of measured score to full score; a higher score indicated better health, and >70% was considered good health status. t test, Kruskal-Wallis H test, and Spearman correlation were used to analyze the scores of SRHMS and the demographic and occupational-related factors affecting the scores of physical, mental, and social health sub-scales. Results A total of 2989 valid questionnaires were recovered. There were statistically significant differences in total score and the scores of physical, mental, and social health among medical staff of different age, educational background, length of service, and weekly working hours groups (P < 0.05). The percentage of total score to full score in the medical staff was 71.41%, but the scores of physical, mental, and social health sub-scales and total scale of selected participants were all lower than the corresponding domestic norms (t=−3.323, −12.283, −7.157, −9.659, P < 0.05); the percentage of psychological symptoms and negative emotions in mental health scale to full score was the lowest, only 58.39%. Educational background, length of service, and weekly working hours were negatively correlated with physical health score (r=−0.061, −0.060, −0.165, P < 0.05); professional title was positively correlated with mental health score (r=0.045, P < 0.05), while educational background and weekly working hours were negatively correlated with it (r=−0.051, −0.172, P < 0.05). Monthly income, professional title, and length of service were positively correlated with social health score (r=0.040, 0.049, 0.071, P < 0.05), while educational background and weekly working hours were negatively correlated with it (r=−0.038, −0.110, P < 0.05). Conclusion The self-rated health status of selected medical staff in Lanzhou is generally good, but lower than that of the norm, especially the mental health score is the lowest. The self-rated health score of total scale is correlated with education, length of service, professional title, and working time per week.
RESUMO
Objective To analyze the association between hexokinase 2 (HK2) gene expression and clinical pathological characteristics in renal clear cell carcinoma using database and bioinformatics methods. Methods Oncomine database was used to analyze the most significant differentially expressed genes between renal clear cell carcinoma and non-kidney tissue. The expression levels of mRNA and protein were detected by GPEIA and The Human Protein Atlas database. Correlation of HK2 expression level between clinicopathological features and prognosis of renal clear cell carcinoma was analyzed using LinkedOmics and KM-plotter databases, respectively. The STRING database was used to predict the potential protein interaction mechanism. Results The most significant difference protein in renal clear cell carcinoma, i.e. HK2, was found, which was highly expressed in renal clear cell carcinoma tissues, and positively correlated with pathological stage, T stage and N stage of renal cell carcinoma (all P<0.05). The overall survival rate of the renal clear cell carcinoma patients with high expression of HK2 was significantly lower than that of the patients with low expression (P<0.05). Conclusions High expression of HK2 gene may be associated with pathological staging, high T stage, high N stage, and poor prognosis of renal clear cell carcinoma.

RESUMO
The aim of this study was to establish a fast and accurate method for developing specific DNA sequences and PCR primers for the detection of Staphylococcus aureus. An automatic C++ program for genomic comparison was used to identify specific DNA sequences from the genome of S. aureus MRSA 252. Four primer pairs were obtained from 9 specific target sequences by comparison of 2656 coding sequences with our local genome database, and 2 pairs of primers were confirmed to be specific to S. aureus by PCR evaluation against 137 bacterial strains, including 11 species of Staphylococcus. Furthermore, the DNA detection sensitivity of primer SA3 was 13.7 fg/microL and the cell sensitivity for this primer was 9.25 x 10(2) CFU/mL. This method has overcome the limitations of specific target mining in conventional assays, and it could be easily and widely used for other foodborne pathogens.
