OBJECTIVE: To analyze the status and influencing factors of the health literacy(HL) of college students in a comprehensive university. METHODS: A total of 3 360 students from in a comprehensive university of Xinjiang Production and Construction Corps was selected using multi-stage stratified cluster random sampling method. The HL level of college students was investigated and evaluated with self-edited Xinjiang Construction Corps College Students Health Literacy Questionnaire. RESULTS: The HL level of college students was 17.1%. The HL level of medical students was higher than that of non-medical students(35.4% vs 10.0%, P<0.01). Logistic regression analysis results showed that among the medical students in grade three or four, those with medium and excellent academic achievement, and Han nationality had a positive effect on their HL level(P<0.01). Among the non-medical students, female and medicine related optional courses had a positive effect on their HL level(P<0.05). Students in the sophomore year had a negative effect on their HL level(P<0.05). CONCLUSION: There is a big difference in the level of HL between medical students and non-medical students. Medical college students and non-medical college students have different factors affecting HL, medical education is related to improving HL.
RESUMEN
Objective:To construct and confirm a predictive model for the risks of cardiovascular diseases (CVD) with metabolic syndrome (MS) and its factors in Xinjiang Kazakh population.Methods:A total of 2 286 Kazakh individuals were followed for 5 years from 2010 to 2012 as baseline survey. They were recruited in Xinyuan county, Yili city, Xinjiang. CVD cases were identified via medical records of the local hospitals in 2013, 2016 and 2017, respectively. Factor analysis was performed on 706 MS patients at baseline, and main factors, age, and sex were extracted from 18 medical examination indexs to construct a predictive model of CVD risk. After excluding the subjects with CVD at baseline and incomplete data, 2007 were used as internal validation, and 219 Kazakhs in Halabra Township were used as external validation. Logistic regression discriminations were used for internal validation and external validation, as well as to calculate the probability of CVD for each participant and receiver operating characteristic curves.Results:The prevalence of MS in Kazakh was 30.88%. Seven main factors were extracted from the Kazakh MS population, namely obesity factor, blood lipid and blood glucose factor, liver function factor, blood lipid factor, renal metabolic factor, blood pressure factor, and liver enzyme factor. The area under the curve (AUC) for predicting CVD in the internal validation was 0.773 (95% CI 0.754-0.792). In the external validation, the AUC for predicting CVD was 0.858 (95% CI 0.805-0.901). Conclusions:The CVD risk prediction model constructed by 7 main factors extracted from Kazakh MS patients has high validation efficiency and can be used for risk assessment of CVD in Xinjiang Kazakh population.
RESUMEN
There are still some controversies about the timing of inguinal hernia surgery, the treatment of uterine round ligament, and the preference for laparoscopic or open surgery for women of childbearing age. For females of childbearing age, the recurrence rate of inguinal hernia is required low after herniorrhaphy. However, the number of samples available for observation is small. Currently, there is no international standard and guidelines for the treatment of female inguinal hernia. For women of childbearing age with fertility requirements, herniorrhaphy is more prudent. The authors elaborate on strategies for treatment of inguinal hernia in female of childbearing age.

The gastric cancer cell line MGC-803 was divided into silencing control group (NC group), PRMT6 silencing group (si-PRMT6 group), nuclear factor-κB (NF-κB/p65) overexpression group (pcDNA-p65 group), si-PRMT6+ pcDNA-p65 group and PRMT6 silencing and matrix metalloproteinase 9 (MMP9) overexpression group (si-PRMT6+ pcDNA-MMP9 group). Western blotting was used to detect the protein expression levels of PRMT6, NF-κB/p65 and MMP9. CCK-8 kit and Transwell assay were used to measure cell proliferation and migration rates.Results:The results of qRT-PCR showed that the relative expression levels of PRMT6 mRNA in GSE-1, AGS, SGC-7901 and MGC-803 cells were 1.041±0.114, 2.141±0.132, 2.716±0.231, 2.825±0.300, and the difference among the four groups was statistically significant ( F=46.082, P<0.001). Compared with GSE-1 cells, PRMT6 mRNA expression levels were significantly increased in AGS, SGC-7901 and MGC-803 cells (all P<0.001). Western blotting results showed that the relative expression levels of PRMT6 protein in GSE-1, AGS, SGC-7901 and MGC-803 cells were 1.090±0.101, 2.847±0.331, 2.925±0.419 and 3.278±0.463, with a statistically significant difference ( F=22.683, P<0.001).

After 48 hours of silencing PRMT6 in MGC-803 cells, in NC group and si-PRMT6 group, the PRMT6 mRNA expression levels were 0.921±0.110 and 0.303±0.045, the PRMT6 protein expression levels were 1.032±0.105 and 0.289±0.043, the cell proliferation activities were 0.917±0.089 and 0.660±0.069, the cell migration rates were (89.122±5.109)% and (30.831±4.463)%, and the p-p65/p65 protein relative expression ratios were 0.947±0.143 and 0.285±0.023. The relative expression levels of PRMT6 mRNA and protein, cell proliferation activity, cell migration rate, protein relative expression ratio of p-p65/p65 in si-PRMT6 group were significantly lower than those in NC group, with statistically significant differences ( t=9.006, P<0.001; t=11.338, P<0.001; t=3.954, P=0.017; t=14.881, P<0.001; t=7.919, P<0.001). Western blotting results showed that the MMP9 protein relative expression levels in NC group, si-PRMT6 group, pcDNA-p65 group and si-PRMT6+ pcDNA-p65 group were 1.202±0.138, 0.318±0.018, 2.849±0.217 and 1.595±0.194, with a statistically significant difference ( F=127.410, P<0.001). Further pairwise comparison showed that the protein relative expression level of MMP9 in si-PRMT6 group was significantly lower than that in NC group ( P<0.001), while that in si-PRMT6+ pcDNA-p65 group was significantly lower than that in pcDNA-p65 group ( P=0.002). Then, MGC-803 cells were co-transfected with si-PRMT6 and pcDNA-p65 or pcDNA-MMP9 for 48 h. The cell proliferation activities in NC group, si-PRMT6 group, si-PRMT6+ pcDNA-p65 group and si-PRMT6+ pcDNA-MMP9 group were 0.923±0.054, 0.608±0.024, 0.818±0.035 and 0.807±0.029, with a statistically significant difference ( F=37.343, P<0.001). Further pairwise comparison showed that the cell proliferation activity of si-PRMT6+ pcDNA-p65 group or si-PRMT6+ pcDNA-MMP9 group was significantly higher than that of si-PRMT6 group (both P<0.001). The cell migration rates of above four groups were (85.195±3.176)%, (28.419±1.845)%, (60.490±7.231)% and (53.653±6.761)%, with a statistically significant difference ( F=59.672, P<0.001). Further pairwise comparison showed that the cell migration rate of si-PRMT6+ pcDNA-p65 group or si-PRMT6+ pcDNA-MMP9 group was significantly higher than that of si-PRMT6 group ( P=0.002; P=0.003). Conclusion:PRMT6 silencing can inhibit the proliferation and migration of gastric cancer cells MGC-803 via deactivation of NF-κB/MMP9 signaling pathway.

RESUMEN
Objective:To compare the prognosis of patients with a single compared to multiple colorectal cancer liver metastases (CRLM) after hepatectomy.Methods:The clinical data of 490 patients with colorectal cancer liver metastases who underwent hepatectomy at Department of Hepatopancreatobiliary Surgery Ⅰ, Peking University Cancer Hospital & Institute from January 2006 to December 2016 were retrospectively studied. There were 314 males and 176 females. The median age was 58 years (range 21 to 83 years). There were 200 patients in the single liver metastasis group and 290 patients in the multiple liver metastases group. The tumor recurrence and survival outcomes on follow-up were analyzed. Survival curves were plotted using the Kaplan-Meier method. Both overall survival and disease-free survival between two groups were compared by the log-rank test. Univariate and multivariate Cox regression analyses were used to analyze independent risk factors of overall survival.Results:The 1-, 3-, 5-, 10-year overall survival rates for the single versus the multiple liver metastases groups were 92.5%, 58.6%, 51.0%, 38.8% versus 90.7%, 53.2%, 41.1%, 29.9%. The differences were significant ( P<0.05). The disease-free survival was also significantly better in the single than the multiple groups ( P<0.05). Cox multivariate analysis showed that right-sided primary colonic tumor, preoperative carbohydrate antigen 19-9 level ≥50 U/ml, and RAS mutant were independent factors influencing survival in patients with single liver metastasis; while primary colonic tumor N 1-2, liver metastases diameter ≥5 cm, and RAS mutant were independent factors influencing survival in patients with multiple tumors. If the three independent factors affecting overall survival of patients with multiple liver metastases were assigned 1 point for each factor, the number of patients with scores of 0, 1, 2, and 3 were 50, 145, 84, and 11, respectively. The long-term survival of patients with a low score (0, 1) was similar to those with a single liver metastasis (both P>0.05). However, patients with a high score (2, 3) showed significantly worse long-term survival when compared with patients with a single liver metastasis (both P<0.05). Conclusions:The prognosis of patients with single colorectal liver metastasis was better than those with multiple liver metastases after hepatectomy. For patients with multiple liver metastases with fewer associated risk factors, surgical resection could still result in long-term survival outcomes which were comparable to those patients with a single liver metastasis.
RESUMEN
Objective To study the impact of RAS status on prognosis of patients after liver resection for colorectal cancer liver metastases (CRLM).Methods The data of 545 consecutive CRLM patients who underwent liver resection at the Hepatopancreatobiliary Surgery Department I,Peking University Cancer Hospital between January 1st,2008 and December 31st,2016,were retrospectively reviewed.According to the inclusion and exclusion criteria,356 patients were eventually included into this study.There were 232 males and 124 females,with ages ranging from 21 to 83 years.The clinical and follow-up data of patients with wild-type and mutant RAS were compared.Survival was estimated by the Kaplan-Meier method,and the difference was compared by the log-rank test.Factors influencing survival of these patients were assessed by univariate and multivariate Cox regression analyses.Results There were 247 patients with wild-type RAS and 109 patients with mutant RAS,respectively.The median overall survival of patients with wild-type and mutant RAS were 74 and 30 months respectively.Compared with mutant RAS patients,wild-type RAS patients had significantly better cumulative survival and disease free survival rates (both P ＜ 0.05).Multivariate Cox regression analyses revealed disease free interval from primary to metastases ≤ 12 months (HR =1.673,95％ CI:1.016-2.637),largest hepatic tumor diameter ＞ 5 cm (HR =1.717,95 ％ CI:1.102-2.637),and mutant RAS (HR =1.836,95％ CI:1.322-2.550) were independent risk factors for patients with colorectal cancer liver metastases after hepatic resection.Conclusion Mutant RAS was a poor prognostic factor of survival after liver resection in CRLM patients
RESUMEN
OBJECTIVE@#To investigate the effect of Aurora kinase B (AURKB) silencing-induced autophagy on apoptosis of osteosarcoma 143B cells and the underlying molecular mechanisms.@*METHODS@#Human osteosarcoma 143B cells were transfected with Lv/shAURKB or the negative control vector Lv/shScrambled followed by treatment with chloroquine (CQ) for 24 h. Western blotting was performed to detect the protein expression levels of AURKB, P62, LC3, cleaved caspase-3, Bcl-2, and P-ULK1. Transmission electron microscopy and LC3 dual-label fluorescence method were used to trace the autophagosomes in 143B cells to assess cell autophagy, and the cell apoptosis was detected using flow cytometry and TUNEL assay. Co-immunoprecipitation assay was used to detect the interaction between AURKB and ULK1.@*RESULTS@#The ratio of autophagy-related proteins LC3 II/I and the number of autophagosomes were significantly increased in 143B cells after transfection with Lv/shAURKB ( < 0.05), which significantly increased the expression of cleaved caspase-3 and reduced the expression of Bcl-2 ( < 0.05). Combined treatment of the cells with Lv/shAURKB and the autophagy inhibitor chloroquine obviously restored the expressions of caspase-3 and Bcl-2 ( < 0.05). Transfection with Lv/shAURKB significantly increased the apoptosis rate of 143B cells ( < 0.05), and this effect was significantly antagonized by combined treatment with chloroquine ( < 0.05). AURKB silencing strongly activated the phosphorylation of the autophagy-initiating protein ULK1 in 143B cells ( < 0.05). The results of co-immunoprecipitation assay confirmed when AURKB was immunoprecipitated, ULK1 also precipitated.@*CONCLUSIONS@#Silencing AURKB can induce autophagy by activating ULK1 phosphorylation to promote apoptosis in 143B cells.
RESUMEN
Objective To compare metabolic syndrome(MS)with Framingham risk score as predictors of cardiovascular disease( CVD) among Kazakhs. Methods The participants were the residents who had been followed up for more than 5 years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting development of CVD using Cox regression and receiver operating characteristic curve. Results The incidence of CVD was 13.87％. The incidence of CVD was higher in the MS group than it in the non-MS group(21.59％ vs 11.10％, P<0.001). The area under the receiver operating characteristic(ROC)curve of MS risk score was significantly larger than that of MS classification(0.727 vs 0.585, P<0.001);the area under the curve of MS risk score was close to that of Framingham risk score ( 0. 732 vs 0.727, P=0.673). The association between CVD and each quintile of MS risk score was more significant than that between Framingham risk score and CVD under the same exposed condition(4.61、9.33、14.15、22.29对3.69、6.36、8.47、16.99) . Conclusion MS risk score that included age may be a better predictor of CVD among Kazakhs.

Adverse Drug Event(ADE)is a major factor threatening patient safety.For now,the ADE detecting in China mostly relies on spontaneous reporting,a method detecting only a small proportion of ADEs,instead of reflecting the real-world clinical medication safety.Global Trigger Tool (GTT)is a relatively new method for detecting ADEs.This paper described the GTT as an effective and practical method for detecting ADEs,by introducing the history of GTT development,GTT basic principles,operating procedures,current relevant researches and application at home and aboard and comparing with other ADE detection methods.The GTT can evaluate the clinical medication safety in various medical institutions.In particular,it can target specific clinical departments or certain people to detect ADEs for obtaining more evidences of clinical medication safety.That is the reason that we recommend medical institutions at all levels learn and use GTT.
RESUMEN
Background and purpose:MicroRNA(miRNA) is a class of small non-coding RNA playing an important regulatory role in many tumors. This study investigated which miRNA might negatively regulate the expression of Aurora-B in osteosarcoma cells, and to lay the foundation for the further investigation of the effort and regulation of Aurora-B in osteosarcoma malignant phenotype.Methods:Bioinformatics prediction software (http://www.targetscan.org) and luciferase assays were used to investigate which miRNA might target to modulate the Aurora-B. Real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot assay were used to further verify which miRNA could negative regulate the expression ofAurora-B gene.Results:Bioinformatics prediction showed let-7 family have the possibility to modulate the expression of Aurora-B; Luciferase assays showed thatAurora-B might be the target gene of let-7a/b/c/d/e/f/g/i; RTFQ-PCR and Western blot analysis testiifed that both the expression levels of Aurora-B mRNA and Aurora-B protein were signiifcantly decreased in Let-7a/g/i up-regulated U2-OS and HOS cells, compared to the cells in the negative control group; but in Let-7b/c/d/e/f up-regulated U2-OS and HOS cells, the expression levels of Aurora-B mRNA and Aurora-B protein have no signiifcant difference, compared to the cells in the negative control group.Conclusion:Let-7a/g/i may downregulate the expression of Aurora-B in human osteosarcoma cells.
RESUMEN
Objective To investigate the relationship between polymorphisms of PPARγ gene(rs1801282, rs3856806 and rs4684847) and hypertension in Uygur. Methods Polymorphisms of PPARγ gene,rs1801282, rs3856806 and rs4684847, were identified in 145 hypertension patients and 165 healthy volunteersby matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Results(1)Frequencies of rs1801282 CC genotype and C allele were 75.9% and 87.2% in hypertension grouprespectively, which were higher than those in control group (63.6% and 79.7%, respectively, P 0.05). (5) SBP in rs1801282 CC genotypecarriers was higher than in CG / GG gene ones, whereas TC was opposite (P < 0.05). Conclusions In theUygur, individuals with CC genotype and C allele at rs1801282 of PPARγ gene are at higher risk ofhypertension. Polymorphism of rs3856806 and rs4684847 may be irrelevant with hypertension in the Uygur.
RESUMEN
Objective: To observe the characteristics of serum homocysteine (Hcy) distribution and the epidemiological characteristics of high serum level of Hcy (HHcy) in Kazakh population. Methods: The stratiifed cluster random sampling method was used to investigate 1003 kazakh individuals in Xinyuan county of Xinjiang including 433 male and 570 female, and they were individuals into 5 age groups:①(25-34) years, n=333,②(35-44) years, n=306, ③(45-54) years, n=230, ④(55-65) years, n=90, ⑤>65 years, n=44. The questionnaire survey, physical check-up and blood biochemical examination were performed and compared among different groups. Results: ① The geometrical mean of Hcy was 13.3μmol/L, and the male was higher than female as 16.0μmol/L vs 11.6μmol/L. ②By age stratiifcation, the serum levels of Hcy elevated with the increased age accordingly. Except for those with the age>65 years, the serum levels of Hcy were all higher in male than female in other 4 age groups. ③The average rate of HHcy prevalence was 31.5%, and the male was higher than female as 49.9%vs 17.5%.④The average rate of H type hypertension prevalence was 35.1%, and the male was higher than female as 44.3%vs 28.1%. There were 87.6%of H type hypertensive patients with H type hypertension, and the male was higher than female as 95.0%vs 80.0%, all P Conclusion: The serum levels of Hcy were different from gender and age; the prevalences of HHcy and H type hypertension were higher in Kazakh population at Xinyuan county of Xinjiang. Community intervention should be conducted to improve the public health condition in Kazakh population.
