Ankylosing spondylitis is a chronic immunoinflammatory disease that mainly affects the spine and the sacroiliac joint， the mechanism of which is closely related to signaling pathways， such as osteoprotegerin （OPG）/receptor activator of nuclear factor-κB （RANK）/RANK ligand， mitogen-activated protein kinase （MAPK）， Wnt/β-catenin （β-catenin）， phosphoinositide 3- kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）. Traditional Chinese medicine has the characteristics of multiple components and targets， and is widely used for the treatment of autoimmune diseases due to its low toxicity， strong specificity， and high efficacy. This review found that monomers and compounds of traditional Chinese medicine can exert anti ankylosing spondylitis effects by intervening in the aforementioned signaling pathways， regulating immune inflammatory responses， and inhibiting biological processes such as bone destruction， ectopic osteogenic differentiation， cell apoptosis， and autophagy.

OBJECTIVE: To assess the impact of albumin (Alb) administration on the prognosis of patients with acute kidney injury (AKI). METHODS: Clinical data of AKI patients in the intensive care unit (ICU) were retrospectively analyzed from the American Medical Information Mart of Intensive Care-IV (MIMIC-IV), including demographic data, acute physiology score (APS), comorbidities, vital signs, laboratory indicators, treatment status, ICU length of stay, and outcome indicators. The main outcome measure is ICU mortality. AKI patients were divided into Alb infusion group and Alb non infusion group based on whether they received Alb treatment. Multiple imputation was used to process missing data and eliminate variables that missing more than 30%. To ensure the stability of the results, propensity score matching (PSM) and inverse probability weighting (IPW) were used to correct the results. Using Kaplan-Meier survival curve and Cox proportional hazards regression model to evaluate the effect of Alb infusion on ICU survival rate in AKI patients. Perform subgroup analysis based on patient age, gender, and comorbidities to evaluate the prognostic effects of Alb on different patient subgroups. RESULTS: A total of 6 390 AKI patients were included, including 1 721 in the Alb infusion group and 4 669 in the Alb non infusion group. After adjusting for key covariates in the Cox regression model, compared with the Alb non infusion group, patients in the Alb infusion group were significantly younger in age, with APS III score, proportion of vasoactive drugs and continuous renal replacement therapy (CRRT) use, sepsis proportion, heart rate, respiratory frequency, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (Cr), lactic acid (Lac), and arterial partial pressure of carbon dioxide (PaCO₂) levels significantly higher. The proportion of hypertension, myocardial infarction, and congestive heart failure, as well as blood pressure, urine output, platelet count (PLT), and Alb levels were significantly lower. The results of univariate and multivariate Cox regression analysis on the raw data showed that the risk of death in the Alb infusion group was significantly lower than that in the Alb non infusion group [hazard ratio (HR) = 0.69, 95% confidence interval (95%CI) was 0.60-0.80, all P < 0.05]. The results after propensity score matching (PSM) and inverse probability weighting (IPW) processing are consistent with the original data trend (both P < 0.05). The Kaplan-Meier survival curve showed that the cumulative survival rate during ICU stay in the Alb infusion group was significantly higher than that in the Alb non infusion group (24.48% vs. 12.17%, Log-Rank test: χ² = 74.26, P < 0.05). Subgroup analysis shows that Alb infusion has a more significant survival benefit for AKI patients who use vasoactive drugs, have concurrent sepsis, and do not have liver disease. CONCLUSION Albumin infusion can decrease the ICU mortality of AKI patients.

Objective:To explore the surgical intervention strategy for metastatic cervical lymph nodes surrounding the carotid artery in head and neck squamous cell carcinoma.Methods:A total of 62 patients with advanced head and neck tumors and carotid wrap by disease treated in Department of Otorhinolaryngology and Head and Neck Surgery, the Affiliated BenQ Hospital of Nanjing Medical University between June 2019 and December 2023 were reviewed, of whom 9 patients presented with metastatic squamous cell carcinoma in cervical lymph nodes of unknown primary or with no recurrence of primary lesion and all the 9 patients were males, aged from 48 to 79 years old, with≤level 2 of Eastern Cooperative Oncology Group-Performance Status (ECOG-PS). Radiographically common carotid artery (CCA) and/or internal carotid artery (ICA) were surrounded by≥270° with tumor. All the 9 patients received implantation of covered stent in carotid artery and radical resection of metastatic cervical lymph nodes. The success rate, complications, surgery-related complications, local recurrence rate, quality of life (QOL) and overall survival (OS) were analyzed. The QOL of patients was compared by paired rank sum test, and P<0.05 indicated statistically significant difference. The OS was analyzed by Kaplan-Meier. Results:The success rate of stent implantation was 100%, with no implantation-related complications. R0 resection was performed in 8 cases and R1 resection in 1 case. The QOL of patients after surgery was improved, and the improvements in "pain", "mood" and "anxiety" were statistically significant( Z values were -2.236, -2.460 and -2.200, respectively, and all P values were<0.05). Follow-up was 1-18 months, with a median of 7 months, and 1 case was lost to follow-up. Local recurrence occurred in 3 patients with an incidence of 37.5% (3/8). OS was 59.9% at 12 months after surgery. Conclusion:Implantation of covered stent in carotid artery combined with radical resection is an effective method for the treatment of cervical lymph node metastasis.

hippocampus and HT22 cells of hypoxia pre-acclimated(HPC)mice and their relationship with neuroprotection.Methods(1)Thirty-six male Institute of Cancer Research(ICR)mice were randomly divided into three groups according to the random number table method of complete randomization:the control group,the hypoxia group and the hypoxia preconditioning group,with 12mice in each group.Mice in the control group were not exposed to hypoxia,mice in the hypoxia group were exposed to hypoxia once,and mice in the hypoxia preconditioning group were exposed to hypoxia four times.Immediately after the end of hypoxia treatment,all mice were decapitated and killed and hippocampal tissues were isolated and preserved in groups.(2)HT22 cells were cultured in medium containing 10％foetal bovine serum and 100 U/ml penicillin-streptomycin.When cell confluence was greater than 90％,they were transferred to 24-well plates for culture and then processed in 2 batches.6 pmol disordered small interfering RNA(siRNA),MALAT1 siRNA(siMALAT1),NEAT1 siRNA(siNEAT1),siMALAT1+siNEAT1 were transfected into the negative control group,siMALAT1 group,siNEAT1 group,and siMALAT1+siNEAT1 group of the first batch of HT22 cells one by one by transfection reagent,and the blank group did not have any treatment;then they were cultured under normal conditions(5％CO2 and 95％air)for 48 h.In the second batch of HT22 cells,6 pmol of disordered siRNA,disordered siRNA,siMALAT1,siMALAT1,siNEAT1 and siNEAT1 were transfected one by one correspondingly to the negative control group and the negative

mRNA([1.26±0.06]vs.[1.00±0.01]),and NR2B protein([1.47±0.05]vs.[1.00±0.01])was increased in the hypoxia group as compared to the control group(all P＜0.05),whereas the relative expression of NEAT1([1.02±0.10]vs.[1.00±0.03])were not statistically significant(P＞0.05),and the relative expression of MALAT1([1.12±0.13]vs.[1.00±0.08])and NEAT1([2.88±0.10]vs.[1.00±0.03])were increased in hypoxic preconditioned group.Compared with hypoxia group,the relative expression of NR2B mRNA([0.54±0.07]vs.[1.26±0.06])and NR2B protein([1.17±0.07]vs.[1.47±0.05])were decreased(both P＜0.05).(2)The differences in the relative expression of NR2B mRNA(F=36.92)and NR2B protein(F=56.98)after transfection of HT22 cells in the five groups were statistically significant(both P＜0.05).Compared with the negative control group,siMALAT1 group(NR2B mRNA:[2.04±0.08]vs.[0.94±0.04],NR2B protein:[1.72±0.13]vs.[0.93±0.02]),siNEAT1 group(NR2B mRNA:[2.15±0.13]vs.[0.94±0.04],NR2B protein:[1.87±0.46]vs.[0.93±0.02]),siMALAT1+siNEAT1 group(NR2BmRNA:[2.09±0.16]vs.[0.94±0.04],NR2B protein:[2.07±0.30]vs.[0.93±0.02])showed the relative NR2B mRNA and NR2B protein expression were increased(all P＜0.05).(3)Differences in relative expression of haematopoietin breakdown product(145/150 kDa)protein(F=12.43),haematopoietin breakdown product(120 kDa)protein(F=7.15),and activated cysteamine protease protein 3 protein(F=6.61)were statistically significant in the 6 groups of HT22 cells transfected and treated with OGD/R(all P＜0.05).Compared with the siMALAT1 group,the siMALAT1+OGD/R group had 145/150kDa([1.42±0.48]vs.[0.85±0.34]),120 kDa([1.33±0.37]vs.[0.52±0.19])haematopoietin catabolism products and activated cysteamine protease protein 3([2.43±0.35]vs.[1.15±0.24])relative expression increased(all P＜0.05);compared with the negative control+OGD/R group,the siMALAT1+OGD/R group showed an increase in 145/150kDa([1.42±0.48]vs.[1.23±0.17]),120 kDa([1.33±0.37]vs.[0.80±0.21])relative expression of haematopoietin breakdown products and activated cysteamine protease protein 3([2.43±0.35]vs.[1.46±0.39])increased(all P＜0.05);compared with the siNEAT1 group,the siNEAT1+OGD/R group had a higher expression of 145/150 kDa([1.28±0.44]vs.[0.87±0.32]),120 kDa([0.81±0.36]vs.[0.63±0.16])relative expression of haematopoietic proteolytic products and activated cysteamine protease protein 3([1.51±0.45]vs.[1.01±0.27])increased(all P＜0.05).(4)The difference in HT22 cell survival rate among the 6 groups was statistically significant(F=5.54,P＜0.05).Compared with the negative control group,HT22 cell survival was decreased in the siMALAT1,siNEAT1,siMALAT1+OGD/R and siNEAT1+OGD/R groups([0.65±0.40],[0.76±0.35],[0.24±0.17],[0.23±0.16]vs.[0.84±0.04],all P＜0.05);cell viability was reduced in the siMALAT1+OGD/R group compared with the siMALAT1 group([0.24±0.17]vs.[0.65±0.40],P＜0.05);and cell viability was reduced in the siNEAT1+OGD/R group compared with the siNEAT1 group([0.23±0.16]vs.[0.76±0.35],P＜0.05).Conclusion HPC increased the expression of MALAT1 and NEAT1 in the hippocampus of mice,and MALAT1 and NEAT1 may participate in the neuroprotective effect of mice after ischemia and hypoxia by affecting the expression of NR2B.

Transcatheter peripheral arterial embolization via transfemoral access(TFA)has been one of the most commonly used interventional treatments.Peripheral artery embolization via transradial access(TRA)has several advantages such as fewer complications at the puncture site,high patient comfort and satisfaction,short hospitalization stay,etc.when compared to TFA,therefore,in clinical practice its application frequency is constantly increasing.However,the clinical application,the postoperative complications,and the study of procedure-related instruments used for peripheral arterial embolization via TRA are still poorly recognized.This paper aims to make a comprehensive review about the clinical application and research status of peripheral arterial embolization via TRA,and to discuss the current challenges and the future development direction of this technique.

BACKGROUND: Epidemiological studies have demonstrated a causal relationship between ambient ozone (O 3 ) and mortality from chronic obstructive pulmonary disease (COPD), which is the only outcome considered in the Global Burden of Disease Study 2021 for O 3 . This study aims to evaluate the temporal trend and spatial distribution of the COPD burden attributable to O 3 across China from 1990 to 2021. METHODS: The ambient O 3 concentrations in China were estimated. Based on the methodology framework and standard analytical methods applied in the Global Burden of Disease Study 2021, we estimated the annual number, age-standardized rate, and percentage of deaths and disability-adjusted life-years (DALYs) from COPD attributable to O 3 pollution during 1990-2021 at the national and provincial levels in China. RESULTS: In 2021, a total of 125.7 (95% uncertainty interval [UI], 26.4-228.3) thousand deaths and 1917.5 (95% UI, 398.7-3504.6) thousand DALYs from COPD were attributable to ambient O 3 pollution in China, accounting for 9.8% (95% UI, 2.1-17.0%) and 8.1% (95% UI, 1.8-14.1%) of the total COPD deaths and DALYs, respectively. Generally, a higher burden was observed among males, the elderly, and the population residing in regions with worse health conditions. The age-standardized rates of COPD deaths and DALYs per 100,000 populations ranged from 0.5 (95% UI, 0-1.4) and 8.1 (95% UI, 0.7-20.9) in Hong Kong to 22.8 (95% UI, 3.9-43.5) and 396.6 (95% UI, 68.9-763.7) in Xizang. From 1990 to 2021, there was a notable decrease in the age-standardized rates of COPD-related deaths (68.2%, 95% UI, 60.1-74.9%) and DALYs (71.5%, 95% UI, 63.7-77.6%), especially in regions with poor health conditions. However, the attributable numbers and percentages changed relatively marginally. CONCLUSIONS Ambient O 3 pollution is a major contributor to the COPD burden in China. Our findings highlight the significant spatial heterogeneity across different provinces and underscore the implementation of geographically tailored policies to effectively reduce O 3 pollution and alleviate the associated disease burden.

Accumulating studies suggest that, as the subway is one of the important means of transport in cities, airborne microorganisms in its system have potential effects on human health, but previous studies have mainly focused on some foreign cities. We reviewed the spatio-temporal distribution characteristics of airborne microorganisms in subway stations in different cities, including diurnal, weekly, and seasonal variations, and the distribution of microorganisms in different regions of the world. The factors affecting airborne microorganisms, such as human activities, temperature and humidity, ventilation, and particulate matter, were presented. The potential health effects were described. Although there was no significant risk of infection from using subway, many pathogens do exist in the air. The influence of microorganisms in subway air on health has become a public health problem that cannot be ignored.

Objective:To investigate the risk factors for combined coronary microvascular dysfunction (CMD) in patients with ischemia and non-obstructive coronary artery disease (INOCA).Methods:From October 2020 to May 2022, 100 INOCA patients with myocardial ischemic symptoms who underwent coronary angiography (CAG) suggestive of <50% stenosis in all three coronary arteries at the Tenth People′s Hospital of Tongji University were prospectively recruited. Myocardial perfusion imaging (MPI), transthoracic echocardiography and cadmium-zinc-telluride (CZT) SPECT coronary flow quantification were performed in the same month, and 93 INOCA patients (36 males and 57 females, age (63.0±10.9) years) were finally included. CMD was defined as coronary flow reserve (CFR)<2.5. Independent-sample t test, Mann-Whitney U test and χ2 test were used to compare MPI results and left ventricular volume parameters between CMD and non-CMD groups. ROC curve analysis was used to analyze the efficacy of each index in predicting CMD, and independent risk factors for CMD were screened by multivariate logistic regression analysis. Results:Among 93 INOCA patients, 29 were in the CMD group and 64 were in the non-CMD group. The age, proportion of hypertension, left ventricular mass index (LVMI), summed stress score (SSS), summed difference score (SDS), left ventricular internal diameter systolic (LVIDS), interventricular septum thickness (IVST), and left ventricular posterior wall thickness (LVPWT) in the CMD group were higher than those in the non-CMD group ( t values: 2.42-3.76, χ2=8.94, z values: -3.31, -3.41, all P<0.05). ROC curve analysis showed that LVMI, SSS, SDS, LVPWT, IVST and age were significant in predicting CMD (AUCs: 0.67-0.72). Multivariate logistic regression analysis showed that LVMI (odds ratio ( OR)=1.08, 95% CI: 1.01-1.17), SDS ( OR=5.37, 95% CI: 1.95-14.78), hypertension ( OR=5.68, 95% CI: 1.34-24.18) and age ( OR=1.10, 95% CI: 1.03-1.18) were risk factors for CMD. Conclusion:LVMI, SDS, hypertension and age are strongly associated with combined CMD in INOCA patients, which can be used for early risk stratification of INOCA patients.

Both natural ginsenoside F2 and unnatural ginsenoside 3β,20S-Di-O-Glc-DM were reported to exhibit anti-tumor activity. Traditional approaches for producing them rely on direct extraction from Panax ginseng, enzymatic catalysis or chemical synthesis, all of which result in low yield and high cost. Metabolic engineering of microbes has been recognized as a green and sustainable biotechnology to produce natural and unnatural products. Hence we engineered the complete biosynthetic pathways of F2 and 3β,20S-Di-O-Glc-DM in Saccharomyces cerevisiae via the CRISPR/Cas9 system. The titers of F2 and 3β,20S-Di-O-Glc-DM were increased from 1.2 to 21.0 mg/L and from 82.0 to 346.1 mg/L at shake flask level, respectively, by multistep metabolic engineering strategies. Additionally, pharmacological evaluation showed that both F2 and 3β,20S-Di-O-Glc-DM exhibited anti-pancreatic cancer activity and the activity of 3β,20S-Di-O-Glc-DM was even better. Furthermore, the titer of 3β,20S-Di-O-Glc-DM reached 2.6 g/L by fed-batch fermentation in a 3 L bioreactor. To our knowledge, this is the first report on demonstrating the anti-pancreatic cancer activity of F2 and 3β,20S-Di-O-Glc-DM, and achieving their de novo biosynthesis by the engineered yeasts. Our work presents an alternative approach to produce F2 and 3β,20S-Di-O-Glc-DM from renewable biomass, which lays a foundation for drug research and development.

This cross-sectional study aimed to investigate the quality of care of diabetes in Shanghai, China. A total of 173 235 patients with type 2 diabetes in 2017 were included in the analysis. Profiles of risk factors and intermediate outcomes were determined. The patients had a mean age of 66.43 ± 8.12 (standard deviation (SD)) years and a mean diabetes duration of 7.95 ± 5.53 (SD) years. The percentage of patients who achieved the target level for HbA_1c (< 7.0%) was 48.6%. Patients who achieved the target levels for blood pressure (BP) < 130/80 mmHg and low-density lipoprotein-cholesterol (LDL-c) < 2.6 mmol/L reached 17.5% and 34.0%, respectively. A total of 3.8% achieved all three target levels, and the value increased to 6.8% with an adaptation of the BP target level (< 140/90 mmHg) for those over 65 years. Multivariable analysis identified the factors associated with a great likelihood of achieving all three target levels: male, young age, short diabetes duration, low body mass index, macrovascular complications, no microvascular complications, prescribed with lipid-lowering medication, and no prescription of antihypertensive medication. In conclusion, nearly 50% and one-third of the patients with diabetes met the target levels for HbA_1c and LDL-c, respectively, with a low percentage achieving the BP target level. The percentage of patients who achieved all three target levels needs significant improvement.
