It is of great significance to control weight and blood pressure reasonably and maintain good living habits and mental state for preventing and improving asymptomatic arrhythmia.

Background Job burnout has become an important factor affecting the mental and physical health and work efficiency of college counselors, and indirectly affects the quality and development of talent cultivation for college students. Objective To explore the relationship between job stress, job crafting, and job burnout among college counselors, and to test the mediating role of job crafting between job stress and job burnout, in order to take targeted measures to alleviate job stress and job burnout of college counselors, reduce associated health risks, and improve the effectiveness of higher education. Methods An anonymous questionnaire survey was conducted among 400 counselors from social network communication groups by convenience sampling. The Counselor Work Stress Scale, Job Crafting Scale, and Maslach Burnout Inventory-General Survey were used. Harman's single-factor method was used to evaluate common method bias in the survey data. One-way ANOVA was applied to test the difference in job stress, job crafting, and job burnout among college counselors by demographic characteristics, and chi-square test was used to analyze the difference in reporting job burnout. Partial correlation analysis was used to evaluate the correlation between selected variables. Structural equation modeling was used to analyze the relationship of job stress, job crafting, and job burnout among college counselors, and Bootstrap analysis was used to test if there was a mediating effect of job crafting on the relationship between job stress and job burnout. Results Of the 390 questionnaires recovered, there were 338 valid questionnaires (86.67%). Among the included subjects, the mean scores of job stress, job crafting, and job burnout were (2.70±0.62), (3.77±0.62), and (2.09±1.09), respectively. The positive rate of job burnout was 76.9% (260/338), with a positive rate of 72.8% in exhaustion dimension and 59.8% in cynicism dimension. There were significant differences in job crafting scores among the college counselors by different genders and professional titles (P<0.05). Female counselors had significantly higher job burnout scores and positive rates than male counselors (P<0.05). The partial correlation analysis showed that job stress, work load, school evaluation and expectation, and interpersonal relationship were positively correlated with job burnout (r=0.562, 0.442, 0.473, and 0.455, respectively, P<0.01), and negatively correlated with job crafting (r=−0.271, −0.169, −0.246, and −0.247, respectively, P<0.01); job crafting, cognitive crafting, relationship crafting, and task crafting were negatively correlated with job burnout (r=−0.447, −0.452, −0.366, and −0.340, respectively, P<0.01). The modified structural equation modeling indicated that job stress negatively affected job crafting (b=−0.348, P<0.001) and positively affected job burnout (b=0.454, P<0.001); job crafting negatively affected job burnout (b=−0.459, P<0.001), and played a partial mediating role in the relationship between job stress and job burnout, and the effect value was 0.160 (95%CI: 0.102, 0.230) that accounted for 26.10% of the total effect. Conclusion Job burnout among the college counselors is prominent. Job crafting presents an inhibitory effect on job burnout. Job stress indirectly affects the occurrence of job burnout by inhibiting the generation of job crafting.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

BACKGROUND: TRIM proteins are important members of E3 ubiquitin ligases, and many studies have confirmed that TRIM family members play an important role in the development of various tumors. We found that TRIM59 expression level in non-small cell lung cancer (NSCLC) was significantly increased through second-generation sequencing. The purpose of this study was to investigate the expression of TRIM59 in NSCLC and its relationship with the clinicopathological parameters as well as the prognosis of patients. METHODS: The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets were excavated to analyze the expression of TRIM59 mRNA in NSCLC and its relationship with the prognosis of patients; The expression of TRIM59 protein in 90 tumor tissues and adjacent tissues was detected by immunohistochemical staining, and the relationship between the expression of TRIM59 protein and clinicopathological parameters and prognosis was analyzed. RESULTS: Overexpression of TRIM59 mRNA in tumor tissues predicted poor prognosis. The expression level of TRIM59 protein was significantly higher in tumor tissues than in adjacent tissues, and TRIM59 protein expression was correlated with tumor size (P=0.007), tumor differentiation (P=0.009), tumor-node-metastasis (TNM) stage (P=0.003) and lymph node metastasis (P=0.003). Multivariate Cox regression analyses showed that along with TNM stage, overexpression of TRIM59 could be considered an independent prognostic factor for NSCLC patients. CONCLUSIONS The expression of TRIM59 is closely related to the prognosis of NSCLC patients, and it is an independent risk factor for NSCLC patients.

Objective:To investigate the clinical characteristics of pregnant women with leukemia, the condition of leukemia and the influence of clinical treatment on maternal and infant outcomes, and to explore the best clinical management method of leukemia in pregnancy.Methods:Among 79 890 pregnant and lying-in women in Qilu Hospital of Shandong University from January 2004 to December 2015, 22 cases (0.028%) were with leukemia, including 5 cases of leukemia diagnosed before pregnancy [all acute myeloid leukemia (AML)] and 17 cases of leukemia diagnosed for the first time after pregnancy [9 cases of AML, 5 cases of chronic myeloid leukemia (CML), 2 cases of acute lymphoblastic leukemia (ALL), and 1 case of chronic lymphocytic leukemia (CLL)]. According to the gestational weeks of admission and confirmed gestational weeks of leukemia, the 22 patients were divided into early-stage group (initial gestational week < 14 weeks, 5 cases), mid-stage group (newly diagnosed gestational week ≥ 14 weeks and < 28 weeks, 11 cases), and late-stage group (newly diagnosed gestational week ≥ 28 weeks, 6 cases, including 2 cases with previous diagnosis of leukemia). The final pregnancy outcomes included abortion, induced labor, premature delivery, full-term delivery and maternal and infant death. The effects of clinical treatment and obstetric treatment of leukemia on the final maternal and infant outcomes, follow-up to understand the progress of primary disease and fertility of pregnant women, and the impact of leukemia and pregnancy treatment on long-term health status of infants were analyzed.Results:Among 22 patients with leukemia in pregnancy, 14 cases (63.6%) (5 cases in early-stage group and 9 cases in mid-stage group) choosed to give up pregnancy, including 4 cases of early pregnancy abortion and 10 cases of mid pregnancy induced abortion; 12 cases of 14 cases were induced abortion or induced labor after leukemia remission induced by advanced chemotherapy. The remaining 8 patients (2 cases in mid-stage group and 6 cases in late-stage group) continued pregnancy and gave birth to live infants, of which 3 cases received chemotherapy before delivery.Conclusions:Gestational leukemia is a high-risk obstetric case, but it is still expected to achieve good pregnancy outcome under good management and treatment. On the basis of following the principles of leukemia treatment, according to the gestational weeks and patients' wishes, the individualized clinical management plan is formulated, and the accurate chemotherapy timing is conducive to the prognosis of mother and infant.

Objective:To investigate the variation of CD4 + /CD8 + ratio and related influencing factors after receiving antiviral treatment for HIV/AIDS in Shandong province. Methods:HIV/AIDS patients in Shandong province initially received HAART from 2010 to 2015, at least 15 years old with the CD4 + T and CD8 + T cell count tested at baseline, 6 months, 1 year, 2 years, 3 years, 4 years and 5 years after treatment initiation were selected. According to their retrospectively collected baseline and follow-up data, the variation of CD4 + /CD8 + and the related influencing factors were described and analyzed by using rank sum test and generalized estimating equation(GEE). Results:A total of 557 subjects were included in the study. The median baseline CD4 + /CD8 + ratio was 0.20, and the CD4 + /CD8 + ratio was inverted in 99.82% of the patients. The proportion of patients with CD4 + /CD8 + ratio > 1 was 0.18% at baseline, and increased to 13.11% after 5 years of treatment. The trend of time change was statistically significant ( χ2 =95.01, P< 0.05). The result of GEE analysis showed that baseline CD4 + T lymphocytes count level and baseline symptoms/signs were the main factors influencing the variation trend of CD4 + /CD8 + ratio. Conclusions:After 5 years of antiviral treatment with HIV/AIDS in Shandong province, the CD4 + /CD8 + ratio increased significantly. Baseline CD4 + T cell count level and baseline symptoms/signs of patients are the main factors affecting the rate of improvement of CD4 + /CD8 + ratio.
