Objective:To evaluate the effect of hydrogen on lipopolysaccharide (LPS) and nigericin-induced pyroptosis in macrophages and the role of long non-coding RNA (lncRNA) nuclear-enriched abundant transcript 1 (NEAT1).Methods:Human monocyte-derived macrophages THP-1 cells were cultured in vitro and divided into 4 groups ( n=25 each) using a random number table method: control group (group C), LPS and nigericin group (group LN), hydrogen-rich medium+ LPS and nigericin group (group H+ LN), and lentiviral transfection+ hydrogen-rich medium+ LPS-nigericin group (group LV+ H+ LN). THP-1 cells were cultured in the common culture medium for 24 h in group C. LPS at a final concentration of 100 ng/ml and nigericin 10 μmol/L were added to the culture medium, and the cells were incubated for 24 h in group LN. In group H+ LN, the culture medium was replaced with 0.6 mmol/L hydrogen-rich medium, then LPS at a final concentration of 100 ng/ml and nigericin 10 μmol/L were immediately added, and the cells were incubated for 24 h. In group LV+ H+ LN, THP-1 cells over-expressing NEAT1 stably after being transfected with lentivirus were used, then LPS at a final concentration of 100 ng/ml and nigericin 10 μmol/L were immediately added, and the cells were incubated for 24 h. Cell viability was detected by CCK-8 assay. Lactic dehydrogenase (LDH) release was assessed by colorimetric method. The amount of LDH released was measured by colorimetry. The concentrations of interleukin-1beta (IL-1β) and IL-18 in culture medium were measured by enzyme-linked immunosorbent assay. The pyroptotic rate was detected by flow cytometry. The expression of nucleotide-binding oligomerization domain-like receptor-containing pyrin domain 3 (NLRP3), apoptosis-associated speck-like protein (ASC), caspase-1 and gasdermin D (GSDMD) was detected by Western blot. The expression of NEAT1 gene was determined by quantitative real-time polymerase chain reaction. Results:Compared with group C, the cell viability was significantly decreased, the amount of LDH released, concentrations of IL-1β and IL-18, and pyroptotic rate were increased, and the expression of NEAT1 gene, NLRP3, ASC, caspase-1 and GSDMD was up-regulated in group LN ( P<0.05). Compared with group LN, the cell viability was significantly increased, the amount of LDH released, concentrations of IL-1β and IL-18, and pyroptotic rate were decreased, and the expression of NEAT1 gene, NLRP3, ASC, caspase-1 and GSDMD was down-regulated in group H+ LN ( P<0.05). Compared with group H+ LN, the cell viability was significantly decreased, the amount of LDH released, concentrations of IL-1β and IL-18, and pyroptotic rate were increased, and the expression of NEAT1 gene, NLRP3, ASC, caspase-1 and GSDMD was up-regulated in group LV+ H+ LN ( P<0.05). Conclusions:Hydrogen can ameliorate LPS and nigericin-induced pyroptosis in macrophages, and the mechanism may be associated with down-regulating the expression of lncRNA NEAT1.

BACKGROUND:The number of hip fracture patients with dementia is increasing with an aging population,posing challenges for surgical treatment. OBJECTIVE:To determine the effect of dementia on postoperative complications in older patients with hip fractures. METHODS:Patients aged over 60 years old with hip fractures from 2000 to 2019 at Chinese PLA General Hospital were included.Dementia patients with a preexisting diagnosis of dementia at admission were identified.Each dementia patient was matched,for age±5 years,gender,and fracture type with 10 non-dementia patients.The differences in postoperative complications were compared between the two groups,including pneumonia,respiratory failure,gastrointestinal bleeding,urinary tract infection,surgical site infection,deep venous thrombosis,pulmonary embolism,angina pectoris,arrhythmia,heart failure,myocardial infarction,stroke,and death.The impact of dementia on major complications was evaluated using multivariate conditional logistic regression. RESULTS AND CONCLUSION:A total of 2 887 patients were included,of whom 125(4.3%)were dementia patients and matched with 1 243 non-dementia patients.The average age of dementia patients was(80.6±7.4)years;64.8%were female;53.6%were intertrochanteric fractures,and 46.4%were femoral neck fractures.Major complications occurred in 25(20.0%)patients with dementia and 123(9.9%)patients without dementia(P<0.01).The risk of major complications was 200.0 per 1 000 persons(95%CI,139.3-278.6)in dementia patients and 99.0 per 1 000 persons(95%CI,83.6-116.9)in non-dementia patients.Multivariate conditional logistic regression showed that a 2-fold risk of major postoperative complications after hip fracture surgery was found in dementia patients than in those without dementia(adjusted OR,2.11;95%CI,1.08-4.10).The results show that dementia is an independent risk factor for postoperative complications in elderly patients with hip fractures.Appropriate preoperative risk assessment and corresponding preventive and therapeutic measures should be given to this vulnerable population to mitigate postoperative complications.

Objective:To investigate the incidence and mortality of breast cancer in tumor registration areas of Shanxi Province in 2019.Methods:A cross-sectional study was conducted. The tumor registration data reported by 13 tumor registration areas in Shanxi Province in 2019 were collected, and the overall incidence and mortality of breast cancer were analyzed. The stratified analysis was conducted by gender and region, and the incidence, mortality, accumulation rate (0-74 years old), age-specific incidence rate, age-specific mortality rate, Chinese population standardized rate and world population standardized rate were calculated. The standard population was based on the 2000 China population census standard population composition and Segi world standard population composition.Results:In 2019, there were 871 new cases of breast cancer in the tumor registration areas of Shanxi Province, with an incidence rate of 17.83/100 000, and 202 deaths, with a mortality rate of 4.13/100 000. The age-specific incidence of breast cancer was at a low level in 0-25 years old, it increased rapidly after 30 years old, and reached a peak in people aged 60 years old. The age-specific mortality showed a slow rising trend with the increase of age, and increased rapidly in people over 75 years old. The age-specific incidence and mortality of breast cancer in female were higher than those in male. Although the general trend of change concerning urban and rural age-specific incidence was similar, the trend of change concerning urban and rural age-specific mortality had their own characteristics. In 4 urban tumor registration areas, the highest male and female Chinese population standardized incidence rates were found in Yuci District of Jinzhong City (0.62/100 000) and Yangquan City (41.86/100 000). Male Chinese population standardized mortality rate was 0/100 000, and the highest female Chinese population standardized mortality rate was found in Yangquan City (12.62/100 000). In 9 rural tumor registration areas, the highest male and female Chinese population standardized incidence rates were found in Jishan County (2.59/100 000) and Pingding County (36.42/100 000). The highest Chinese population standardized mortality rates were found in Yuanqu County (0.89/100 000) and Jishan County (4.82/100 000).Conclusions:Women, urban area people and middle-aged and elderly people are the foci of breast cancer prevention and control in Shanxi Province.

The current linear economy model relies on fossil energy and increases CO₂ emissions, which contributes to global warming and environmental pollution. Therefore, there is an urgent need to develop and deploy technologies for carbon capture and utilization to establish a circular economy. The use of acetogens for C1-gas (CO and CO₂) conversion is a promising technology due to high metabolic flexibility, product selectivity, and diversity of the products including chemicals and fuels. This review focuses on the physiological and metabolic mechanisms, genetic and metabolic engineering modifications, fermentation process optimization, and carbon atom economy in the process of C1-gas conversion by acetogens, with the aim to facilitate the industrial scale-up and carbon negative production through acetogen gas fermentation.
