Serine/arginine-rich splicing factor 7 (SRSF7), a known splicing factor, has been revealed to play oncogenic roles in multiple cancers. However, the mechanisms underlying its oncogenic roles have not been well addressed. Here, based on N⁶-methyladenosine (m⁶A) co-methylation network analysis across diverse cell lines, we find that the gene expression of SRSF7 is positively correlated with glioblastoma (GBM) cell-specific m⁶A methylation. We then indicate that SRSF7 is a novel m⁶A regulator, which specifically facilitates the m⁶A methylation near its binding sites on the mRNAs involved in cell proliferation and migration, through recruiting the methyltransferase complex. Moreover, SRSF7 promotes the proliferation and migration of GBM cells largely dependent on the presence of the m⁶A methyltransferase. The two m⁶A sites on the mRNA for PDZ-binding kinase (PBK) are regulated by SRSF7 and partially mediate the effects of SRSF7 in GBM cells through recognition by insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2). Together, our discovery reveals a novel role of SRSF7 in regulating m⁶A and validates the presence and functional importance of temporal- and spatial-specific regulation of m⁶A mediated by RNA-binding proteins (RBPs).

BACKGROUND: Anorexia nervosa (AN) is a psychological disorder, which is characterized by the misunderstanding of body image, food restriction, and low body weight. An increasing number of studies have reported that the pathophysiological mechanism of AN might be associated with the dysbiosis of gut microbiota. The purpose of our study was to explore the features of gut microbiota in patients with AN, hoping to provide valuable information on its pathogenesis and treatment. METHODS: In this cross-sectional study, from August 2020 to June 2021, patients with AN who were admitted into Peking University Third Hospital and Peking University Sixth Hospital ( n   =  30) were recruited as the AN group, and healthy controls (HC) were recruited from a middle school and a university in Beijing ( n   =  30). Demographic data, Hamilton Depression Scale (HAMD) scores of the two groups, and length of stay of the AN group were recorded. Microbial diversity analysis of gut microbiota in stool samples from the two groups was analyzed by 16S ribosomal RNA (rRNA) gene sequencing. RESULTS: The weight (AN vs. HC, [39.31 ± 7.90] kg vs. [56.47 ± 8.88] kg, P  < 0.001) and body mass index (BMI, AN vs. HC, [14.92 ± 2.54] kg/m 2vs. [20.89 ± 2.14] kg/m 2 , P  < 0.001) of patients with AN were statistically significantly lower than those of HC, and HAMD scores in AN group were statistically significantly higher than those of HC. For alpha diversity, there were no statistically significant differences between the two groups; for beta diversity, the two groups differed obviously regarding community composition. Compared to HC, the proportion of Lachnospiraceae in patients with AN was statistically significantly higher (AN vs. HC, 40.50% vs. 31.21%, Z  = -1.981, P  = 0.048), while that of Ruminococcaceae was lower (AN vs. HC, 12.17% vs. 19.15%, Z  = -2.728, P  = 0.007); the proportion of Faecalibacterium (AN vs. HC, 3.97% vs. 9.40%, Z  = -3.638, P  < 0.001) and Subdoligranulum (AN vs. HC, 4.60% vs. 7.02%, Z  = -2.369, P  = 0.018) were statistically significantly lower, while that of Eubacterium_hallii_group was significantly higher (AN vs. HC, 7.63% vs. 3.43%, Z  = -2.115, P  = 0.035). Linear discriminant effect (LEfSe) analysis (LDA score >3.5) showed that o_Lachnospirales, f_Lachnospiraceae, and g_Eubacterium_hallii_group (o, f and g represents order, family and genus respectively) were enriched in patients with AN. Microbial function of nutrient transport and metabolism in AN group were more abundant ( P  > 0.05). In AN group, weight and BMI were significantly negatively correlated with the abundance of Bacteroidota and Bacteroides , while positively correlated with Subdoligranulum . BMI was significantly positively correlated with Firmicutes; HAMD scores were significantly negatively correlated with Faecalibacterium. CONCLUSIONS The composition of gut microbiota in patients with AN was different from that of healthy people. Clinical indicators have correlations with the abundance of gut microbiota in patients with AN.

Objective:To investigate health literacy level and its influencing factors of 7, 945 Kazakh residents in Yili Prefecture, Xinjiang, China.Methods:Participants were enrolled from rural or urban Kazakh permanent residents aged 18 to 75 years living within the city and four counties of Yili Prefecture, Xinjiang, from April to November 2019. Stratified random sampling was adopted to divided the sites into five layers: Yining city, Gongliu County, Nilk County, Xinyuan County and Zhaosu County. According to the calculation of actual sample size, a total of 7, 945 subjects were selected. A health literacy questionnaire was used to determine the different demographic characteristics and health literacy status of Kazakh residents.Results:A total of 7, 945 cases, with mean age of (40.6±11.6) years, including 3, 391 males (42.68%) and 4, 554 females (57.32%) were studied. The total health literacy score was (45.8±17.2). In this study, we aimed to identify health literacy status of at least 424 cases(5.34%). The number of people with safety and first aid literacy was the largest, with a total of 2, 437 cases (30.67%). The number of people with health information access literacy and infectious disease prevention literacy was relatively small, with 860 (10.82%) and 866 cases (10.90%), respectively. Univariate analysis results showed that there were statistically significant differences (all P<0.05) in the scores of marital status, age, education level, personal monthly income, occupation, and household health literacy level. The results of multiple linear regression analysis showed that the main influencing factors of Kazakh residents′ health literacy were marital status, educational level, personal monthly income, occupation, and household registration. Conclusion:The health literacy of Kazakh residents in Yili prefecture, Xinjiang is at a low level, among which literacy in health information access and infectious disease prevention and control were the lowest. Ultimately, marital status, education level, personal monthly income, occupation, household registration, and other factors can have an impact on the level of health literacy.

Objective: This study aimed to explore and analyze the correlation between pulse pressure index (PPI), body mass index (BMI), and cerebral hemodynamics and evaluate their significance in early screening for stroke. Methods: The subjects were selected from those who had completed the cerebral blood flow function test in the First Affiliated Hospital of Xinjiang Medical University from January to December 2018. First, basic information and disease history of the respondents were obtained through on-site questionnaire survey. Height, weight, and blood pressure were measured, and BMI, pulse pressure, PPI, and mean arterial pressure were calculated. Meanwhile, cerebral hemodynamic monitoring was completed. Individuals with cerebral hemodynamic indexes ≥75 were classified as normal cerebrovascular function group and those with cerebral hemodynamic indexes <75 as abnormal group. This study divided the PPI into three subgroups: high, medium, and low. According to the Chinese Adult Overweight and Obesity Prevention and Control Guidelines, the BMI was divided into too low, normal, overweight, and obese. The correlations of PPI and BMI with cerebral hemodynamics in different groups were calculated and compared. Results: A total of 12 375 subjects, aged (52.6±7.3) years, were included in the study, consisting of 7 275 men (58.79%) and 5 100 women (41.21%). There were 9 900 patients (80.00%) in the normal group and 2 475 patients (20.00%) in the abnormal group. The abnormal rate of cerebral hemodynamics was higher in the Han nationality； those with a history of hypertension, diabetes, and hyperlipidemia. Moreover, those with abnormal cerebral hemodynamic indicators had a higher BMI, systolic pressure, diastolic pressure, pulse pressure and PPI, mean arterial pressure was higher than the normal group (all P<0.001). In different PPI groups, the average blood flow, average velocity, maximum velocity, minimum velocity, and critical pressure level of the left and right sides showed a downward trend with the increase in PPI. Peripheral resistance, pulse wave velocity, characteristic impedance, dynamic resistance, and difference between diastolic and critical pressure all showed an upward trend with the increase in PPI. In different BMI groups, the average blood flow in the obese group on the left side was lower than that in the underweight, normal, and super recombination groups. The average blood flow in the obese group on the right side was lower than that in the normal and super recombination groups and higher than that in the subhypoxia group. The mean, maximum, and minimum velocities of the left and right sides decreased with the increase in BMI. The differences in peripheral resistance, pulse wave velocity, characteristic impedance, dynamic resistance, critical pressure level, diastolic blood pressure, and critical pressure showed an increasing trend with the increase in BMI, and the differences of the above indicators were statistically significant (all P <0.001).The results of unconditional multivariate logistic regression analysis showed that Han nationality, history of hypertension, history of diabetes, PPI, and BMI were the main risk factors for abnormal cerebral hemodynamics. The higher the PPI and BMI, the higher the risk of abnormal cerebral blood flow. Conclusion The higher the PPI and BMI, the higher the possibility of abnormal cerebral hemodynamic indexes. Extremely high PPI and BMI should be paid greater attention.

Objective: The purpose of the present study was to evaluate of continuous metabolic syndrome score (cMetS) in screening metabolic syndrome (MetS) and to determine the cut-off values in a representative sample of Xinjiang population aged 15 to 18 years old. Methods: A stratified cluster sampling was used to select participants aged 15-18 years from 13 cities in Xinjiang. cMetS was calculated by summing up the Zscores of standardized waist circumference, mean arterial pressure, high-density lipoprotein, triglyceride, and fasting blood glucose by age and gender. Results: Totally 16.3% of subjects were overweight, and 5.2% were obese. The proportion of overweight and obesity in males was significantly higher than that in females (18.1% vs 13.8%)(6.0% vs. 4.1%)(χ2=15.36，7.89，P<0.05). The prevalence of total MetS was 6.1%, with 6.6% and 5.4% for men and women, respectively. There was a correlation between cMetS and MetS components, and the average cMetS value increased with increasing MetS component(P<0.05). The total cut-off value of cMetS was 0.99 (sensitivity 68.0%, specificity 80.7%), and the area under the ROC curve was 84.9%. The cMetS scores for boys and girls were 0.80 and 1.48, respectively. Conclusion Compared with MetS, cMetS shows more accuracy in screening MetS among youth aged 15-18 years in both gender.

Objective:To investigate the influence of the prevalence and co-prevalence of risk factors for metabolic syndrome on the scores of different levels of metabolic syndrome in people receiving physical examination in Urumqi.Methods:Using the 2017 Xinjiang Health Examination Database, a total of 175 927 people from 7 districts and 1 county in Urumqi were selected as subjects. Face-to-face survey and body measurements were used to collect cardiovascular risk factors and metabolic syndrome scores. Metabolic syndrome scores were used. For the 0-5 points at 6 levels, χ2, χ2 trend test, correlation analysis of ordered variable Kendall’s tau-b, and logistic regression analysis of ordered results were used to analyze the influence of prevalence and co-prevalence of behavioral risk factors on the MS scores. Results:The percentages of 6 metabolic syndrome scores in the sample population were 23.82 %, 27.87 %, 22.41 %, 16.03 %, 8.02 %, and 1.85 %, respectively. The scores of metabolic syndrome were different in different age groups, ethnic groups, groups with different drinking rates, and groups with different dietary types, with the differences all significant ( P<0.05).The MS score in men increased with the increase of oil/salt rate and excessive drinking rate ( P<0.01). The score in women increased with the increase of the current smoking rate, oil/salt rate, and increased with the decrease of physical activity ( P≤0.01). There was no significant difference in the distribution of regular drinking rates between different score groups ( P>0.05). The scores of metabolic syndrome increased with the increase of risk factors ( P<0.05). Ordered results logistic analysis found that in the men with ≥3 risk factors and the metabolic syndrome score was 1.15 (1.06-1.26) times higher than that in the men without risk factor, as well as in women with 2 risk factors and≥3 risk factors. The metabolic syndrome scores were 1.38 (1.22-1.55), 2.02 (1.53-2.66) times higher than those in the women without risk factors. Conclusions:The physical examination group in Urumqi, the more the metabolic syndrome disease behavior risk factors clustered, the higher the metabolic syndrome score was. Therefore, comprehensive intervention measures should be taken to control the different forms of metabolic syndrome to prevent the occurrence and progress of the disease.

Objective Analysis of community work personnel's general practitioner engaged in service intention and its influencing factors. Methods Between December 2016 and May 2017, using multi-stage cluster random sampling in the Urumqi area,across 7 community health service centers(CHSC) out of 59 in a county jurisdiction,we randomly selected 1-2 community health service centers in each area county.Wethen randomly selected 8 CHSC staff as the research participants and chose a total of 324 community work personnel, 66 male and 258 female, with an average age of (34.7 ± 10.4) years to complete a questionnaire survey.The general practitioner engaged with theservice staff will use chi-square test analysis and logistic regression analysis on the influencing factors. Results Of 324 medical workers in community health service centers, including 250 of Han ethnic group and 74 minority ethnic group workers, 97.6% workers of Han ethnic group and 95.9% of minority ethnic group had signing service awareness; 92.4% of Han workers would sign system services,and 95.9% of the minority ethnic group staff were willing to sign system services. Single factor analysis found that the staff were familiar with the signing system service, attended the health management training in general medicine,had teacher-training background,had teaching experience,wondered whether to have interns,wondered whether it can save manpower,wondered whether workload could be reduced, wondered whether it can improve compliance, and considered doctor-patient relationship. These nine parameters represented service contracts with the GPS system and showed statistically significant differences (χ2=6.433, 12.913, 5.984, 6.448, 14.593, 20.675, 17.031, 84.829, 97.943, respectively;P< 0.05). In the comparison of Han ethnic group and minority workers' signing intention,the nine indicators showed no significant differences(P>0.05).Conclusion Urumqi Han ethnic group and minority community workers' a wareness of signing service, willingness to sign system services, strengthening community staff of general medicine,and training for health management knowledge and skills are advantageous to the community engaged in service.

Objective:To treat the mixed and deeper infantile hemangioma with ladder dosage propranolol, and to explore its efficacy and safety.Methods:A total of 98 infants with hemangioma were treated by ladder treatment of propranolol.Before treatment,comprehensive assessments of electrocardiogram(ECG),heart color ultrasound, blood glucose,liver function,kidney function,myocardial enzymes and blood routine were conducted.After excluding contraindications,the dose of propranolol incrementally doubled from 0.5 mg·kg-1·d-1 to 4.0 mg·kg-1·d-1.Propranolol was taken 3 times a day.Before and after medication for 1 and 2 h,ECG was monitored.The changes of tumor size,texture,color and other changes or an onset of adverse reactions were dynamicly observed.The infants were visited every month.The efficacy was evaluated using Achauer system.Results: After medication,98 cases had different degrees of color changes or tumor consistency softening.After the dosage of propranolol was increased to 4.0 mg·kg-1·d-1,the change of tumor was the fastest.According to the 4-grade method, there were 84 cases(85.71%) as gradeⅣ (excellent),2 cases (2.04%) as grade Ⅲ (good),4 cases (4.08%) as gradeⅡ (medium)and 8 cases (8.16%) as gradeⅠ (poor).The curative effect of mixed hemangioma was better than that of deeper hemangioma(P<0.05).The recovery time of 74 cases of hemangiomas was 6 months.The major adverse reactions were heart rate decline(5/98,5.10%),drowsiness(3/98,3.06%),diarrhea(7/98,7.14%),loss of appetite (1/98,1.02%), and convulsions (2/98,2.04%).After treatment,all adverse reactions disappeared.Two months after drug withdrawal there were 4 cases of recurrence,and they were continously treated with propranolol.Conclusion: The efficacy of oral ladder dosage propranolol in treatment of mixed and deeper infantile hemangioma is increased significantly and there are no significant adverse reactions.
