Objective: To understand the smoking-related behaviors and influencing factors of current smoking among medical staff in Fengtai District, Beijing Municipality, so as to provide the reference for reducing the current smoking rate of medical staff. Methods: Medical staff in 28 medical and health institutions in Fengtai District were selected as the survey subjects from February to March and July to August 2023. Basic information, smoking and smoking cessation behaviors, and the provision of brief smoking cessation intervention services were collected through electronic questionnaires. Factors affecting current smoking among medical staff were analyzed using a multivariable logistic regression model. Results: Totally 6 716 questionnaires were allocated, and 6 714 valid questionnaires were recovered, with an effective recovery rate of 99.97%. There were 1 590 males (23.68%) and 5 124 females (76.32%). There were 3 315 medical staff in clinical department, accounting for 49.37%. There were 457 current smokers and the current smoking rate among medical staff was 6.81%. The proportion of medical staff in clinical departments who were current smokers and provided brief smoking cessation intervention services was 72.99%, which was lower than that of non-current smokers at 85.18% (P<0.05). Multivariate logistic regression analysis showed that medical staff in secondary and above hospitals (OR=1.454, 95%CI: 1.136-1.862), male (OR=51.158, 95%CI: 34.810-75.183), work experience of 10~<20 years (OR=1.492, 95%CI: 1.065~2.092) or ≥30 years (OR=1.574, 95%CI: 1.011~2.449), those with positions (OR=1.644, 95%CI: 1.159-2.332), and those in logistics departments (OR=2.124, 95%CI: 1.278-3.528) or other departments (OR=2.011, 95%CI: 1.297-3.118) had a higher likelihood of being current smokers. On the contrary, medical staff with a bachelor's or junior college education level (OR=0.487, 95%CI: 0.346-0.685) or a master's degree or above (OR=0.268, 95%CI: 0.159-0.454), and those with an intermediate professional title (OR=0.430, 95%CI: 0.291-0.636) or a senior professional title (OR=0.452, 95%CI: 0.283-0.723) had a lower likelihood of being current smokers. A total of 214 medical staff successfully quit smoking, and the smoking cessation rate was 31.89%. Among them, 20, 18, and 17 medical staff had used the smoking cessation service hotline, visited smoking cessation clinics, and taken smoking cessation medications, respectively. In the past year, 199 medical staff who were current smokers (43.54%) had attempted to quit smoking, and 280 medical staff who were current smokers (61.27%) had the willingness to quit smoking. Conclusions The current smoking rate among medical staff in Fengtai District is relatively high. Hospital level, gender, educational level, work experience, position, professional title, and department are influencing factors for current smoking among medical staff. It is necessary to enhance the willingness of medical staff to quit smoking and their understanding of smoking cessation intervention services, so as to reduce the current smoking rate.

Objective To investigate the serum micro-ribonucleic acid-15a(miR-15a)and macrophage mi-gration inhibitory factor(MIF)levels and their relationship with adverse maternal and infant outcomes in pa-tients with gestational diabetes mellitus(GDM).Methods From January 2020 to December 2022,106 patients with GDM who underwent prenatal examination and gave birth in the Hengshui Fourth People's Hospital were selected as the experimental group.Another 106 healthy women who underwent pregnancy examination and delivered in a hospital during the same period were selected as the control group.Detection of serum miR-15a level by real-time fluorescent quantitative polymerase chain reaction and serum MIF levels were detected by enzyme-linked immunosorbent assay.Serum MIF and miR-15a levels were compared between the two groups,and the relationship between miR-15a and MIF levels and adverse maternal and infant outcomes in GDM patients was analyzed by multivariate Logistic regression.Results The serum levels of miR-15a and MIF in the experimental group were higher than those in the control group,the difference was statistically sig-nificant(P＜0.05).The age of patients with adverse maternal and infant outcomes in the experimental group was＞35 years old,the pre-pregnancy body mass index was＞24 kg/m2,the proportion of patients with ad-verse pregnancy history,poor blood glucose control and serum MIF and miR-15a levels were higher than those with good maternal and infant outcomes in the experimental group,and the differences were statistically sig-nificant(P＜0.05).Multivariate Logistic regression analysis showed that age＞35 years old,pre-pregnancy body mass index＞24 kg/m2,adverse pregnancy history,poor blood glucose control and serum miR-15a and MIF were all risk factors for adverse maternal and infant outcomes in the experimental group(P＜0.05).Conclusion Serum miR-15a and MIF levels are abnormally elevated in GDM patients,and serum miR-15a and MIF levels are closely related to adverse maternal and infant outcomes.

Acute myeloid leukemia (AML) is a common malignant disease of the hematological system, with high EVI1 expression accounting for 8%-10% of adult AML. Studies have shown that high EVI1 expression plays an important role in the treatment and prognosis of AML. In recent years, researchers have continuously revealed the structure and role of EVI1, but its mechanism of mediating AML has not been fully clarified. Therefore, systematically exploring the role of EVI1 in AML may provide a useful reference for the precise treatment of AML patients with high EVI1 expression.

OBJECTIVE: To explore the genetic basis for a child featuring short stature and postaxial polydactyly. METHODS: A child who presented at Ningbo Women & Children's Hospital in May 2021 due to the"discovery of growth retardation for more than two years" was selected as the subject. Peripheral blood samples of the child and his parents were collected for the extraction of genomic DNA. Whole exome sequencing was carried out for the child, and candidate variant was verified by Sanger sequencing of his family members. RESULTS: The child was found to harbor a heterozygous c.3670C>T (p.Q1224) variant of the GLI2 gene, which may lead to premature termination of protein translation. The variant was not detected in either parent. CONCLUSION The child was diagnosed with Culler-Jones syndrome. The c.3670C>T (p.Q1224*) variant of the GLI2 gene probably underlay the disease in this child.

OBJECTIVE To study the protective effects of ligustrazine-scutellarein twin drug ST-11 on rat adrenal medullary pheochromocytoma PC12 cell injury induced by oxygen-glucose deprivation/reperfusion （OGD/R） and its mechanism. METHODS PC12 cells were divided into blank group， model group， nimodipine group （positive control， 5 μmol/L） and different concentration groups of ST-11 （5， 10， 20 μmol/L）. After 24 hours of pre-administration intervention， all the other groups except the blank group were cultured in glucose-free DMEM culture medium containing 10 mmol/L Na2S2O4 for 4 hours with glucose deficiency and hypoxia. After 4 hours of glucose and oxygen re-introduction， the survival rate of cells in each group， the contents of lactate dehydrogenase （LDH）， catalase （CAT）， glutathione （GSH）， malondialdehyde （MDA） and superoxide dismutase （SOD） in cell supernatant， apoptosis rate， the levels of reactive oxygen species （ROS） and mitochondrial membrane potential （MMP）， the protein expressions of B-cell lymphoma 2 related X protein （Bax）， B-cell lymphoma 2 （Bcl-2） and caspase-3 were all detected in each group. RESULTS Compared with blank group， the cell survival rate， the contents of CAT， GSH and SOD in cell supernatant， MMP level， relative expression of Bcl-2 and Bcl-2/Bax ratio in model group decreased significantly （P＜0.05）， while the contents of LDH and MDA， ROS level， apoptosis rate， relative expressions of Bax and caspase-3 were significantly increased （P＜0.05）. Compared with model group， above indexes of ST-11 groups （except for the protein expression of caspase-3 in 5 μmol/L ST-11 group） were reversed signifi-cantly （P＜0.05）. CONCLUSIONS ST-11 has a certain protec-tive effect on OGD/R-injured PC12 cells， and its effects may be related to reduction of oxidative stress and inhibition of cell apoptosis.

ObjectiveTo investigate the association between ZJU index and the onset of nonalcoholic fatty liver disease （NAFLD） in the Uygur population and the value of ZJU index in predicting the risk of NAFLD. MethodsThe Uighur community of The 51st Regiment of The Third Division of Xinjiang Kashgar Corps was selected as the investigation site， and the Uygur residents who lived in this area and had an age of >18 years were selected as subjects. Follow-up studies were conducted in 2019， 2020， and 2021， and the investigation of outcomes was completed in June to August of 2021. Finally 10 597 subjects were enrolled for analysis. The Kruskal-Wallis H test was used for comparison of continuous variables between groups， and the chi-square test was used for comparison of categorical variables between groups. The subjects were divided into Q1-Q4 groups according to the level of ZJU index. The Kaplan-Meier curve was used to predict the incidence rate of NAFLD， and the Cox regression model was used to analyze the association between ZJU index and the risk of NAFLD； the area under the ROC curve （AUC） was used to evaluate the value of ZJU index in predicting the risk of NAFLD. ResultsDuring the median follow-up time of 4.92 years， the incidence rate of NAFLD was 9.4% （992/10 597） among the study population. After adjustment for multiple factors， there was a significant increase in the risk of NAFLD with the increase in ZJU index， with a hazard ratio of 2.55 （95% confidence interval ［CI］： 1.60‍ — ‍4.06）， 7.32 （95%CI： 4.78‍ — ‍11.20）， and 21.74 （95%CI： 14.32‍ — ‍33.00）， respectively （all P_trend<0.001）. The ROC curve showed that ZJU index had a higher value in predicting NAFLD （AUC=0.816）， and the male subgroup had a significantly higher predictive accuracy of ZJU index than the female subgroup （AUC： 0.829 vs 0.809）. ConclusionZJU index is a predictive factor for the onset of NAFLD in the Uygur population in rural areas of Xinjiang and has a good value in predicting the risk of NAFLD.

Objective:To determine the regional boundary of para-aortic lymph node (PAN) metastasis in cervical cancer, and to explore the clinical target volume (CTV) margin.Methods:Eight-six patients with cervical cancer metastasis to PAN below and above left renal vein (LRV) were retrospectively included in this study. The anatomical relationship of the metastatic PANs and surrounding structures were analyzed according tocontrast-enhanced computed tomography (CT) and three dimensional reconstruction images.Results:Eight-six patients had metastatic PANs belowLRV: metastatic nodes were located onthe medial side of ovarian vessels and ureters, behind the renal veins, duodenum, mesenteric vessels, in front of the anterior border of lumbar vertebra and psoas. The inferior mesenteric vein was close to the left anterior side of PANs. Where the duodenum appeared, no node was presenton the anterolateral side of the inferior vena cava (IVC).Above the LRV, 27 patients had retrocrural node involvement along the azygos and hemiazgos vein, and 25/27 cases were located below the junction level of cardia and oesophagus, and 5/27 patients had metastatic lymph nodes between IVC and the right crura of diaphragm, all below the level of coeliac trunk artery.Conclusions:CTV margin delineation of PAN below and above LRV is recommended:superiorly, the junction level of cardia and oesophagus; laterally, crura and the medial side of ovarian vessels and ureters and inferior mesenteric vein; anteriorly, the posterior side of the coeliac trunk artery and renal veins and duodenum, mesenteric vessels; posteriorly, the anterior border of lumbar vertebra and psoas.

Objective:To investigate and analyze the correlation between blood pressure and serum creatinine (Scr) and glomerular filtration rate (GFR).Methods:This research was a cross-sectional study, a total of 46792 people over 20 years old with relatively complete data in the health management center of the First Affiliated Hospital of Xinjiang Medical University from January to December 2018 were included as the research subjects, and baseline data of these study subjects were obtained by on-site questionnaire, collection of blood pressure, creatinine and other physiological and biochemical indicators. The subjects were divided into 20-64 years old group and ≥65 years group according to their age; being treated as the continuous variables (systolic blood pressure, diastolic blood pressure, five categories), their blood pressure indicators were analyzed. The F test, t test, χ2 test and logistic regression model were used to analyze the baseline characteristics of Scr level and GFR, as well as the correlation between blood pressure and Scr and GFR. Results:(1) The average Scr level was (72.89±16.84) μmol/L in the study population aged 20-93. The average GFR was (102.17±17.01) ml·min -1·(1.73 m 2) -1. The average Scr of men was higher than that of women, the average GFR of men was lower than that of women (all P<0.001). (2) Among the subjects above, there were 514 cases (1.10%) with abnormal Scr level and 657 cases (1.40%) with abnormal GFR, the incidence of abnormal Scr and GFR was higher in men, subjects with age ≥65 years old, or diabetes, or hypertension (all P<0.05). (3) There were significant differences in Scr level and GFR in subjects with different gender, age, blood pressure and body mass index (BMI) (all P<0.05). (4) With the increase of blood pressure, among the crowd of 24-64 years old, the relative risk of abnormal Scr and GFR in the group with baseline blood pressure ≥180/110 mmHg was 8.434 and 5.168 times higher than that in the group with baseline blood pressure<120/80 mmHg, respectively, after adjusting variables such as sex, age, nationality, BMI, hypertension, diabetes. However, among the crowd of ≥65 years old, only the relative risk in the group with baseline blood pressure of 160-179/100-109 mmHg was statistically significant compared with<120/80 mmHg. Conclusion:The blood pressure is bound up with Scr and GFR in the crowd of 24-64 years old.

Objective:To explore the current status and influencing factors of self-management of depression in community residents, so as to provide clues and basis for promoting the mental health of community residents.Methods:From June to August 2020, the residents of a community in Jining city in Shandong Province were selected as the survey objects, and 458 permanent residents were selected by simple random sampling method. The self-designed general data questionnaire, Depression Self-management Scale, General Self-Efficacy Scale (GSES) , Simple Coping Style Questionnaire (SCSQ) and Social Support Rating Scale (SSRS) were used to conduct cross-sectional survey, and structural equation was used to analyze the influencing factors of depression self-management of community residents. A total of 458 questionnaires were sent out and 443 were effectively received, with the effective recovery rate of 96.72%.Results:The depression self-management score of 443 community residents was (32.72±5.72) , GSES score was (23.47±5.12) , score of positive coping in SCSQ (2.07±0.51) , score of negative coping in SCSQ was (1.14±0.43) and total score of SSRS (32.89±3.43) . The structural equation model showed that the total effects of self-efficacy, positive coping, negative coping and social support on self-management of depression in community residents were respectively 0.45, 0.42, -0.52 and 0.37 ( P<0.05) . Conclusions:The depression self-management level of community residents is directly or indirectly affected by self-efficacy, coping styles and social support. When conducting mental health publicity and education in the community, it should be based on improving the self-efficacy of residents, coping styles and the level of social support to choose effective methods and content of publicity and education to promote the improvement of the self-management level of individual depression.

Objective To explore the clinical features and prognosis of different PML_RARα fusion gene isoforms in acute promyelocytic leukemia (APL). Methods The clinical data of 78 patients initially diagnosed with APL in Fujian Medical University Union Hospital from February 2013 to July 2016 were collected. The clinical features and prognosis of different PML_RARα fusion gene isoforms were analyzed. Results There were 32 females (41%) and 46 males (59%) in 78 patients, with a median age of 40 years old (13-68 years old). The most common PML_RARα fusion gene was L type (48.7%, 38/78), followed by S type (46.2%, 36/78) and V type (5.1%, 4/78). The patients with white blood cell count more than 10×109/L (high_risk) occurred mostly in S type (61.1%, 22/36), compared with V type and L type, and there were statistically different (χ 2 ＝ 7.683, P < 0.05). A total of 78 patients included 8 cases (10.2%) of combined CD34 positive, 17 cases (21.8%) of combined FLT3_ITD mutation, 12 cases (15.4%) of combined DNMT3A mutation and 9 cases (11.5%) of additional chromosomal abnormalities. There were no significant differences in CD34 positive, FLT3_ITD, DNMT3A, and the incidence of additional chromosomal abnormalities among the three different isoforms (P＞0.05). The most common occurrence of retinoic acid syndrome (RAS) during treatment was S type (21/36), while rare for L type and V type (χ2＝ 7.633, P< 0.05). There were no statistical differences in the complete remission (CR) rate and disease_free survival rate among the patients with different PML_RARα isoforms (P＞0.05). Conclusions The clinical characteristics of different PML_RARα fusion gene isoforms are different, including most_common L type, more_common V type and S type in high risk groups; complicated RAS is commonly found in S type during the treatment. And different isoforms have no effect on the CR and DFS rate.
