Background The high work intensity and possible subsequently increased susceptibility to occupational hazards of calcium carbide plants may lead to hypertension in workers, but there are few studies on the relationship between occupational hazard exposure and hypertension in workers involving the production process of calcium carbide. Objective To explore the influence of occupational hazards on the incidence of hypertension in calcium carbide plants. Methods Using historical cohort design, the employees of a calcium carbide factory in the western part of Inner Mongolia Autonomous Region were selected as research subjects. According to the pre-determined inclusion and exclusion criteria, the study population comprised an exposure group of 377 employees (including furnace workers, inspection workers, and maintenance workers) exposed to dust, noise & carbon monoxide, and a control group of 388 employees (including central control workers, electricians, and administrative personnel) without above-mentioned exposure. The total sample size was 765 participants. The follow-up period was from April 2011 to October 2022, and the study endpoint was defined as the conclusion of the follow-up period or diagnosed hypertension in annual occupational health examination. Information on general demographic characteristics, living habits, and work status was collected from all study subjects. Cox proportional hazards regression model was used to analyze the association between occupational hazard exposure and the risk of hypertension among the calcium carbide plant employees. Results The average age, mean systolic and diastolic blood pressure, proportion of males, smoking rate, and alcohol consumption rate in the exposure group were higher than those in the control group (P<0.05). Compared to baseline, both systolic and diastolic blood pressure levels increased in the exposure group and the control group at the end of the follow-up (P<0.05). At the end of the follow-up, the average differences between systolic/ diastolic blood pressure and baseline values in the exposure group were higher than those in the control group (P<0.05). During the follow-up period, a total of 223 cases of hypertension occurred, with a total follow-up of 2785 person-years, resulting in an incidence density of 8007.18 per 100000 person-years, an average age of onset of (35.90±8.22) years, and an average working age of onset of (2.69±1.97) years. The incidence density in the exposure group was 128.71% higher than that in the control group, and the risk of hypertension in the exposure group was 2.115 times that of the control group. The risk of hypertension was 2.199 times higher for men than for women, 1.344 times higher for those aged 30 and above than for those under 30, 1.546 times higher for smokers than for non-smokers, and 1.750 times higher for drinking workers than for non-drinking ones. The results of Cox proportional hazards regression modeling indicated that the hazard ratio (95%CI) of hypertension among the employees exposed to dust, noise, and carbon monoxide was 2.254 (1.703, 2.982), 1.594 (1.107, 2.295), and 1.567 (1.079, 2.274), respectively, when different covariates (gender, age, smoking, and alcohol consumption) were included. The results of Log-rank test showed that there were statistically significant differences in the distribution of disease-free survival between the exposure group and the control group (P<0.05). Conclusion Occupational exposures to dust, noise, and carbon monoxide may increase the risk of hypertension among calcium carbide plant workers.

Acute skin failure (ASF) is an inevitable damage to the skin and subcutaneous tissue caused by hemodynamic instability and/or low perfusion. At present, there are some understandings and reports about adult ASF at home and abroad, but there are few reports about children's ASF. This article reviewed the definition, pathophysiological changes, risk factors, clinical manifestations, and management of children's ASF, and put forward suggestions in order to provide ideas for clinical diagnosis and treatment of children's ASF, and promote the further study of children's ASF.

OBJECTIVE: To evaluate the value of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) for assessing disease activity in patients with rheumatoid arthritis (RA) treated with tofacitinib. METHODS: This retrospective study was conducted among 98 RA patients in active stage treated with tofacitinib in Third Xiangya Hospital and 100 healthy control subjects from the Health Management Center of the hospital from 2019 to 2021. We collected blood samples from all the participants for measurement of erythrocyte sedimentation rate (ESR), high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and other blood parameters 1 month before and 6 months after tofacitinib treatment. We further evaluated PLR and NLR before and after tofacitinib treatment in the RA patients, and analyzed their correlations with RA disease activity. RESULTS: PLR and NLR increased significantly in RA patients as compared with the healthy controls. In the RA patients, PLR and NLR were positively correlated with the levels of hs- CRP, ESR, IL- 6, Disease Activity Score of 28 joints-ESR (DAS28-ESR), anti-cyclic citrullinated peptide (CCP), and rheumatoid factor (RF) before and after tofacitinib treatment. Tofacitinib treatment for 6 months significantly decreased hs-CRP, ESR, IL-6, CCP, RF and DAS28-ESR levels in the RA patients. CONCLUSION NLR and PLR can be useful biomarkers for assessing disease activity in RA patients treated with tofacitinib.

Objective:To examine the survival rates and clinical characteristics of people with newly discovered non-M 3 acute myeloid leukemia (AML) who carry the ASXL1 gene mutation. Methods:From January 2016 to April 2021, the clinical information of patients with newly diagnosed non-M 3 AML at Shandong University's Qilu Hospital was retrospectively examined, and their clinical characteristics and survival were compared and analyzed. Gene mutation was detected by next-generation sequencing. Results:① The study included 256 AML patients who were initially diagnosed and had complete data, including 47 cases of ASXL1 gene mutation-positive (ASXL1 +) patients and 209 cases of ASXL1 gene mutation-negative (ASXL1 -) patients. All patients were divided into three groups: elderly (≥60 years old, n=92) , middle-aged (45-59 years old, n=92) , and young (≤44 years old, n=72) . ②WBC, and age were higher in patients with ASXL1 mutations compared to ASXL1 - patients, while complete response after the first round of treatment (CR 1) was lower ( P<0.05) . In the elderly group, WBC and the proportion of aberrant cells in nuclear cells in ASXL1 + patients were higher than those in ASXL1 - patients ( P<0.05) . In the young group, the WBC of ASXL1 + patients was higher than that of ASXL1 - patients ( z=-2.314, P=0.021) . ③IDH2 mutation and ASXL1 mutation was related ( P=0.018, r=0.34) . In ASXL1 + patients, the proportion of peripheral blasts in the high VAF group (VAF>40% ) was higher than that in the low VAF group (VAF<20% ) , and the proportion of aberrant nuclear cells was higher in the duplication and replacement mutation patients than in the deletion mutation patients ( P<0.05) . ④The overall survival (OS) and progression-free survival (PFS) of ASXL1 + patients were shorter than those of ASXL1 - patients (median, 10 months vs 20 months, 10 months vs 17 months; P<0.05) . The proportion number of aberrant cells in nuclear cells (≥20% ) , complex karyotypes, and TET2 mutation were all independent risk variables that had an impact on the prognosis of ASXL1 + patients, according to multivariate analysis ( P<0.05) . Conclusion:ASXL1-mutated non-M 3 AML patients have higher WBC in peripheral blood, a higher proportion of aberrant cells in nuclear cells, lower CR 1 rate, and shorter OS and PFS. Additionally, a poor prognosis is linked to higher VAF, duplication, and substitution mutations in the ASXL1 gene, as well as the high proportion of aberrant cells in nuclear cells, complex karyotype, and TET2 mutation.

Diabetes is the most important comorbidity of cardiovascular disease, and cardiovascular disease is the main cause of mortality and disability of patients with type 2 diabetes. In order to standardize the diagnosis and treatment of patients with diabetes and cardiovascular disease, the National Health Commission Capacity Building and Continuing Education Center organized the experts from the field of cardiology and endocrinology systematically reviewing the research progresses and expert experiences of relevant disciplines from home and abroad, and formulated this consensus. This consensus covers the diagnosis, drug treatment, and risk factor management for patients with diabetes and cardiovascular disease (including atherosclerotic cardiovascular disease and heart failure) from the perspective of cardiovascular disease and diabetes management aiming to strengthen the comprehensive management of patients and ultimately to improve the prognosis of patients. The management of cardiovascular diseases mainly includes the management of blood pressure, blood lipids, anti-thrombosis, anti-myocardial ischemia, anti-ventricular remodeling and so on. Diabetes management mainly includes lifestyle intervention (including diet, exercise, weight loss, etc.), anti-hyperglycemia therapy (including drugs and insulin), blood glucose monitoring, and hypoglycemic prevention. In addition, specific clinical recommendations are given to patients with special health care needs such as diabetic nephropathy, elderly (>75 years), and cardiovascular critical illness.
