Acute lung injury(ALI) is a critical clinical condition primarily characterized by refractory hypoxemia and infiltration of inflammatory cells in lung tissue, which can progress into a more severe form known as acute respiratory distress syndrome(ARDS). Immune cells and inflammatory cytokines play important roles in the progression of the disease. Due to its unclear pathogenesis and the lack of effective clinical treatments, ALI is associated with a high mortality rate and severely affects patients' quality of life, making the search for effective therapeutic agents particularly urgent. Ginseng Radix et Rhizoma, the dried root of the perennial herb Panax ginseng from the Araliaceae family, contains active ingredients such as saponins and polysaccharides, which possess various pharmacological effects including anti-tumor activity, immune regulation, and metabolic modulation. In recent years, studies have shown that ginsenosides exhibit notable effects in reducing inflammation, ameliorating epithelial and endothelial cell injury, and providing anticoagulant action, indicating their comprehensive role in alleviating lung injury. This review summarizes the pathogenesis of ALI and the molecular mechanisms through which ginsenosides act at different stages of ALI development. The aim is to provide a scientific reference for the development of ginsenoside-based drugs targeting ALI, as well as a theoretical basis for the clinical application of Ginseng Radix et Rhizoma in the treatment of ALI.

OBJECTIVES: To evaluate the application value of genetic newborn screening (gNBS) in the Yunnan region. METHODS: A prospective study was conducted with a random selection of 3 001 newborns born in the Yunnan region from February to December 2021. Traditional newborn screening (tNBS) was used to test biochemical indicators, and targeted next-generation sequencing was employed to screen 159 genes related to 156 diseases. Positive-screened newborns underwent validation and confirmation tests, and confirmed cases received standardized treatment and long-term follow-up. RESULTS: Among the 3 001 newborns, 166 (5.53%) were initially positive for genetic screening, and 1 435 (47.82%) were genetic carriers. The top ten genes with the highest variation frequency were GJB2 (21.29%), DUOX2 (7.27%), HBA (6.14%), GALC (3.63%), SLC12A3 (3.33%), HBB (3.03%), G6PD (2.94%), SLC25A13 (2.90%), PAH (2.73%), and UNC13D (2.68%). Among the initially positive newborns from tNBS and gNBS, 33 (1.10%) and 47 (1.57%) cases were confirmed, respectively. A total of 48 (1.60%) cases were confirmed using gNBS+tNBS. The receiver operating characteristic curve analysis demonstrated that the areas under the curve for tNBS, gNBS, and gNBS+tNBS in diagnosing diseases were 0.866, 0.982, and 0.968, respectively (P<0.05). DeLong's test showed that the area under the curve for gNBS and gNBS+tNBS was higher than that for tNBS (P<0.05). CONCLUSIONS gNBS can expand the range of disease detection, and its combined use with tNBS can significantly shorten diagnosis time, enabling early intervention and treatment.

OBJECTIVE: To assess the efficacy and safety of Erzhu Jiedu Decoction (EZJDD) Granules in treating mid-advanced hepatitis B virus-associated primary liver cancer (HBV-PLC) patients with Pi (Spleen)-deficiency and dampness-heat syndrome. METHODS: From January 2021 to June 2023, a cohort of 132 patients were enrolled and randomly assigned to a control group or a EZJDD group according to the random numbers, with 66 patients in each group. The patients in the control group received conventional treatment for 3 months, followed by a 3-month follow-up. In addition to the conventional treatment, patients in the EZJDD group were administered EZJDD Granules (10.9 g/pack, 2 packs twice per day) orally for same duration. Progression-free survival (PFS) as primary outcome was evaluated by Kaplan Meier method. Karnofsky performance status (KPS) scores were used to assess the quality of life in two groups before and after treatment, and survival rates were determined as well. The efficacy of Chinese medicine syndrome was calculated with Nimodipine method. Liver function, tumor indicators and T lymphocyte subsets were measured, respectively. Safety indicators were recorded and assessed. RESULTS: Of the 116 patients who completed the study, 57 were in the control group and 59 in the EZJDD group. The median PFS was 3.53 months (106 days) in the EZJDD group compared to 2.33 months (70 days) in the control group (P=0.005). Six-month survival rate was 52.63% (30/57) in the control group and 69.49% (41/59) in the EZJDD group (P=0.039). The median KPS score in the EZJDD group [70(63, 90)] was higher than that in the control group [70(60, 80)] (P=0.013). The total effective rate of CM syndrome was 52.63% (30/57) in the control group and 77.97% (46/59) in the EZJDD group (P=0.005). The levels of alpha fetoprotein, alpha fetoprotein-L3, alpha-L-fucosidase and protein induced by Vitamin K absence or antagonist- II in the EZJDD group increased less than the control group (P>0.05). CD8⁺ levels were decreased, while CD3⁺ and CD4⁺ levels, as well as CD4⁺/CD8⁺ ratio were significantly increased in the EZZJD group (P<0.05). No treatment-related adverse reactions were observed during the study. CONCLUSION EZJDD Granules significantly prolonged the median PFS and improved 6-month survival rate in patients with mid-advanced HBV-PLC (Registration No. ChiCTR2200056922).

OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is a major health concern in northwest China; however, the impact of particulate matter (PM) exposure during sand-dust storms (SDS) remains poorly understood. Therefore, this study aimed to investigate the association between PM exposure on SDS days and COPD hospitalization risk in arid regions. METHODS: Data on daily COPD hospitalizations were collected from 323 hospitals from 2018 to 2022, along with the corresponding air pollutant and meteorological data for each city in Gansu Province. Employing a space-time-stratified case-crossover design and conditional Poisson regression, we analyzed 265,379 COPD hospitalizations. RESULTS: PM exposure during SDS days significantly increased COPD hospitalization risk [relative risk ( RR) for PM _2.5, lag 3:1.028, 95% confidence interval ( CI): 1.021-1.034], particularly among men and the elderly, and during the cold season. The burden of PM exposure on COPD hospitalization was substantially high in Northwest China, especially in the arid and semi-arid regions. CONCLUSION Our findings revealed a positive correlation between PM exposure during SDS episodes and elevated hospitalization rates for COPD in arid and semi-arid zones in China. This highlights the urgency of developing region-specific public health strategies to address adverse respiratory outcomes associated with SDS-related air quality deterioration.

Cognitive dysfunction is one of the serious complications of type 2 diabetes.Exercise interven-tion has a certain effect on improving diabetes cognition,but the exact process remains ambiguous.This research aims to explore the impact and molecular processes of treadmill exercises in enhancing cognitive impairments in type 2 diabetic mice.Ten m/m 8-week-old male mice were used as the control group.Forty db/db mice,each 8 weeks old and male,were categorized into four distinct groups with each group containing 10 mice,including the db/db group(model group),db+Exe group(exercise group),db+Exe+SB203580 group(exercise combined with the p38 MAPK inhibitor group),db+SB203580 group(p38 MAPK inhibitor group).db+Exe group and db+Exe+SB203580 group were subjected to treadmill running intervention(40 min/time,5 times/week,a total of 8 weeks).db+Exe+SB203580 and db+SB203580 group were intraperitoneally injected with SB203580(5 mg/kg,5 times/week,8 weeks)2 hours before treadmill exercise.The results of body weights and fasting blood glucose measurement showed that 8-week treadmill exercise could significantly reduce the body mass and fasting blood glucose levels(P＜0.01);the results of water maze showed that treadmill exercise improved cognitive dysfunction in diabetic mice(P＜0.05).Immunofluorescence staining revealed that treadmill exercise diminished the fluorescence intensity of NLRP3 in hippocampus,and there was a significant difference in CA1 and CA3 regions(P＜0.05).Treadmill exercise reduced the fluorescence intensity of PI in the hippocampus,and there was a significant difference in the DG region(P＜0.01).The results of qRT-PCR revealed that treadmill exercise decreased IL-1β and IL-18 mRNA levels in hippocampus,with a notable difference in IL-1β mRNA levels(P＜0.05).Western blotting analysis revealed that treadmill exercise reduced the concentrations of Caspase3,Caspase9 and Bax in hippocampus(P＜0.01),reduced the concentrations of TXNIP,NLRP3,GSDMD-N,IL-1β,IL-18,Cleaved Caspase1 and Caspasel(P＜0.05),decreased the levels of p-RIPK1,RIPK1,p-RIPK3 and RIPK3(P＜0.05).After adding p38 inhibitors,treadmill ex-ercise combined with p38 inhibitor intervention further inhibited the expression of Caspase3,TXNIP,GS-DMD-N and IL-18(P＜0.05),and the expression levels of Caspase9,Bax,NLRP3,IL-1β,Cleaved Caspase 1 and Caspase 1 also showed a downward trend.The expression of RIPK1 and p-RIPK3 in-creased significantly(P＜0.05),and the protein expression levels of p-p38,p-RIPK1 and RIPK3 showed an upward trend.In conclusion,treadmill running intervention can effectively improve the cogni-tive dysfunction in type 2 diabetic mice,and its mechanism is partly through the p38 MAPK signaling pathway to regulate PANoptosis.

Objective:To establish the absorption and elution test for relatively quantitive obtaining anti-A and anti-B blood group IgG antibodies in the plasma of O-type RhD-positive pregnant women.Methods:95 cases of the O-type RhD-positive pregnant women plasma samples were randomly selected for obtaining the IgG antibodies of anti-A and anti-B blood group,with absorption test under 37 ℃ and elution test under 56 ℃,and the IgG anti-A and anti-B antibody titers of plasma and elution were determined by the microcolumn gel anti-human globulin test.The differences and correlation between the titers of IgG antibodies in the eluent and plasma were compared and analyzed.Results:After a logarithmic transformation(Log2),there was no statistically difference between IgG antibody anti-A difference value and anti-B difference value in the eluent and plasma(P＞0.05).The titer of IgG antibody in the eluent was positively correlated with the titer of IgG antibody in the plasma(r=0.914).The linear equation for IgG antibody titers fitted by a scatter plot between the eluent and plasma was Y=-3.55+0.96X.Conclusion:The absorption and elution test can be used to obtain the anti-A and anti-B IgG antibodies in the plasma of O-type RhD-positive pregnant women,whose plasma origin IgG titer is greater than 8.Meanwhile,the acquisition of anti-A antibodies was as effective as anti-B antibodies at the same time,and the antibodies obtained are positive proportional to their respective concentrations in the plasma.

Objective To understand the prevalence characteristics of influenza and changes of influenza virus strains,and provide reference for the prevention and control of influenza in the province.Methods Surveillance da-ta about influenza in Hunan Province from 2014 to 2023 were exported from China Influenza Surveillance Informa-tion System.Differences in the percentage of influenza-like illness(ILI)cases(percentage of influenza-like cases[ILI％]in outpatient and emergency department visits)among different years and different populations,as well as the positive rate of influenza virus in ILI specimens were compared.Results From 2014 to 2023,over 2.65 million cases of ILI were reported,with an ILI％of 4.70％.ILI％among different years presented statistically significant differences(P＜0.001).People aged 0-14 years old were the main population with ILI,accounting for 82.90％.The positive rate of influenza virus in ILI specimens was 14.14％,the positive rate of influenza virus among diffe-rent years and age groups were both significantly different(both P＜0.001).The main prevalent influenza strains from 2014 to 2023 included types A(H1N1),A(H3N2),B(Victoria),and B(Yamagata),alternating among di-fferent years.However,type B(Yamagata)strains were not detected from 2020 to 2023.There were basically two influenza prevalence seasons every year,namely winter-spring and summer.Conclusion People＜15 years old are the main population of influenza,and the prevalence peaks are in winter-spring and summer.From 2021 to 2023,the prevalence alternates mainly among 3 types:A(H1N1),A(H3N2),and B(Victoria).

Objective To investigate the role and mechanism of exosomes derived from mesenchymal stem cells in hyperbaric oxygen caused pulmonary oxygen toxicity.Methods Mice were divided into the control group that was exposed to normal air,and hyperbaric oxygen exposure groups treated with phosphate buffer saline(PBS)or exosomes,respectively.PBS and exosome treatment were given one day prior to exposure.Mice were subjected to 0.23 MPa pure oxygen for 8 hours.The lung wet-dry ratio,inflammation,exudation and pathological injury were analyzed,while cell death and antioxidant related molecules were detected.Results Pretreatment with exosome significantly attenuated lung injury caused by hyperbaric oxygen exposure by decreasing the lung wet-dry ratio,inflammation,and cell apoptosis.Conclusion Prophylactic administration of exosomes derived from mesenchymal stem cells can alleviate hyperbaric oxygen induced pulmonary oxygen poisoning by attenuating cell death and inflammation.

Analyzing polysorbate 20(PS20)composition and the impact of each component on stability and safety is crucial due to formulation variations and individual tolerance.The similar structures and polarities of PS20 components make accurate separation,identification,and quantification challenging.In this work,a high-resolution quantitative method was developed using single-dimensional high-performance liquid chromatography(HPLC)with charged aerosol detection(CAD)to separate 18 key components with multiple esters.The separated components were characterized by ultra-high-performance liquid chro-matography-quadrupole time-of-flight mass spectrometry(UHPLC-Q-TOF-MS)with an identical gradient as the HPLC-CAD analysis.The polysorbate compound database and library were expanded over 7-time compared to the commercial database.The method investigated differences in PS20 samples from various origins and grades for different dosage forms to evaluate the composition-process relationship.UHPLC-Q-TOF-MS identified 1329 to 1511 compounds in 4 batches of PS20 from different sources.The method observed the impact of 4 degradation conditions on peak components,identifying stable components and their tendencies to change.HPLC-CAD and UHPLC-Q-TOF-MS results provided insights into fingerprint differences,distinguishing quasi products.
