Objective To understand the mortality and potential life loss due to coronary heart disease (CHD) and stroke in Wujiang District, Suzhou from 2011 to 2022, and to provide strategies and basis for the prevention and treatment of CHD and stroke. Methods We collected the data of death cases due to CHD and stroke from the death monitoring system in Suzhou from 2011 to 2022. The mortality of CHD and stroke, potential years of life lost (potential years of life lost , PYLL), average years of life lost (average years of life lost , AYLL) and potential years of life lost rate (potential years of life lost rate , PYLLR) were calculated to analyze the development trend of death and disease burden of CHD and stroke. Results From 2011 to 2022, the crude mortality of CHD was 31.91/10 million, and that of stroke was 118.93/10 million. CHD and stroke mortality rates both showed an upward trend（P＜0.05, a statistically significant trend）. From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District increased rapidly with the increase of age. From 2011 to 2022, the disease burden caused by CHD totaled 11005 person-years, with PYLLR of 1.26% and AYLL of 12.34 years per person. The PYLL caused by stroke was 13 587.5 people-years, the PYLLR was 1.55%, and the AYLL was 8.93 years per person. PYLL, PYLLR and AYLL all decreased in women（P<0.05）, with no significant change in men（P>0.05）. Conclusion From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District appeared a tendency towards a rise, effective intervention and prevention measures should be taken among elderly and male residents.

Gouty arthritis （GA） is an inflammatory disorder caused by monosodium urate （MSU） crystal deposition， accompanied by elevated oxidative stress and aberrant release of inflammatory cytokines， resulting in joint tissue damage and intense pain. Nuclear factor E₂-related factor 2 （Nrf2）， a key transcription factor regulating the antioxidant defence system， exerts cytoprotective effects through dissociation from Kelch-like ECH-associated protein 1 （Keap1） and activates downstream antioxidant response element （ARE）-mediated pathways. It can upregulate the expression of heme oxygenase-1 （HO-1）， NADH quinone oxidoreductase 1 （NQO1）， superoxide dismutase （SOD）， and glutathione transferase （GST） to preserve redox homeostasis. Moreover， Nrf2 can suppress activation of NOD-like receptor protein 3 （NLRP3） inflammasomes， reduce pro-inflammatory cytokine production and release， modulate nuclear factor-κB （NF-κB） transcriptional activity， regulate gut microbiota balance， enhance mitophagy， and inhibit apoptosis， so as to reduce joint inflammation and pain and promote body recovery. This review systematically examined recent advancements in traditional Chinese medicine （TCM） for GA prevention and treatment via regulating the Nrf2 signaling pathway. It delineated Nrf2's molecular mechanisms and its role in GA pathogenesis and elucidated how TCM intervenes in multiple pathways including Keap1/Nrf2/ARE， Nrf2/HO-1（NQO1）， and Nrf2/NF-κB/NLRP3 to exert therapeutic effects. The study demonstrated that TCM monomers and compounds effectively counteract oxidative damage， attenuate inflammatory responses， promote autophagy， and inhibit apoptosis via regulating the Nrf2 signaling pathway. These findings not only clarify the scientific basis of TCM in GA treatment but also offer strategic insights for developing novel Nrf2-targeted anti-gout drugs.

Iron is an essential element for living organisms that plays critical roles in the process of bacterial growth and metabolism. However, it remains to be elucidated whether piuB encoding iron-uptake factor is involved in iron uptake and pathogenicity of Xanthomonas axonopodis pv. glycines (Xag). To investigate the function of piuB, we firstly generated a piuB deletion mutant (ΔpiuB) by homologous recombination. Compared with the wild-type, the piuB mutant exhibited significantly reduced growth and virulence in host soybean. The mutant displayed markedly increased siderophore secretory volume, and its sensitivity to Fe³⁺, Cu²⁺, Zn²⁺ and Mn²⁺ was significantly enhanced. Additionally, the H₂O₂ resistance, exopolysaccharide yield, biofilm formation, and cell mobility of ΔpiuB were significantly diminished compared to that of the wild-type. The addition of exogenous Fe³⁺ cannot effectively restore the above characteristics of ΔpiuB. However, expressing piuB in trans rescued the properties lost by ΔpiuB to the levels in the wild-type. Taken together, our results demonstrated that PiuB is a potential factor for Xag to assimilate Fe³⁺, and is necessary for Xag to be pathogenic in host soybean.

BACKGROUND:Gut microbiota is closely related to host energy balance and metabolism.The metabolites of intestinal flora can regulate the occurrence and development of obesity and can be a new target for the prevention and treatment of obesity. OBJECTIVE:To summarize the interaction between the intestinal flora and obesity,as well as the specific mechanism underlying regulation of obesity by metabolites of intestinal flora,thereby providing a new reference and basis for the prevention and treatment of obesity. METHODS:"Intestinal microbiota,intestinal bacteria,intestinal microbiota metabolites,short-chain fatty acids,bile acids,ipopolysaccharide,trimethylamine N-oxide,medium-chain fatty acids,tryptophan derivatives,obesity"were used as search terms in Chinese and English.Literature related to obesity from 1990 to 2022 was retrieved in PubMed and CNKI databases.According to inclusion and exclusion criteria,88 articles were finally selected. RESULTS AND CONCLUSION:Intestinal flora is closely related to the occurrence and development of obesity.For example,changes in the Firmicutes to Bacteroidetes ratio can be used as a biomarker for the diagnosis of obesity,and the occurrence of obesity can be delayed by the colonization of probiotics such as Bifidobacterium breve,Lactobacillus and Akkermansia.Intestinal flora is mainly mediated by the metabolites of intestinal flora to participate in the regulation of obesity.For example,short-chain fatty acid can regulate adipogenesis by regulating signaling pathways such as G protein-coupled receptors 41,43 and peroxisome proliferator-activated receptor γ,thus delaying the occurrence and development of obesity.Bile acids can increase insulin sensitivity and body energy expenditure by promoting the activation of G protein-coupled receptor 5 and farnesol X receptor.In addition,lipopolysaccharide,trimethylamine oxide,medium-chain fatty acids and tryptophan derivatives are also widely involved in the occurrence and development of obesity through various signaling pathways.Further studies have found that metabolites of the same bacterial community exert heterogeneous effects in the specific process of regulating obesity via different signaling pathways.For example,under the influence of high-fat diet,acetic acids can activate the parasympathetic nervous system,leading to hyperphagia and liver insulin resistance and thus accelerating the physiological course of obesity.

BACKGROUND:Intestinal flora and its metabolites can participate in the pathological process of osteoporosis and play an important role in the diagnosis and treatment of osteoporosis.In addition,exercise can regulate the intestinal flora and thus affect the occurrence and development of osteoporosis. OBJECTIVE:To summarize the effects and mechanism of intestinal flora on osteoblasts,osteoclasts,and bone marrow mesenchymal stem cells,and the potential role of exercise-mediated intestinal flora in regulating osteoporosis. METHODS:"Intestinal flora,intestinal bacteria,metabolites of intestinal flora,bone metabolism,osteoporosis,exercise"were selected as keywords.Literatures from 1990 to 2023 were retrieved from PubMed and CNKI databases. RESULTS AND CONCLUSION:Changes in the abundance and diversity of intestinal flora and changes in the levels of intestinal flora metabolites such as trimethylamine oxide and bile acid can be used as biomarkers for the diagnosis of osteoporosis.The imbalance of intestinal flora can lead to intestinal barrier dysfunction and excessive production of lipopolysaccharides and trimethylamine oxide,induce the secretion of tumor necrosis factor-α and other inflammatory cytokines,activate the nuclear factor κB signaling pathway and aggravate oxidative stress,thus promoting osteoclast differentiation,inducing osteoblast apoptosis and affecting bone marrow mesenchymal cell migration.Remodeling intestinal flora homeostasis can inhibit inflammatory response,downregulate oxidative stress,inhibit osteoclast differentiation,promote osteoblast differentiation,and regulate the osteogenic migration of bone marrow mesenchymal cells to prevent and treat osteoporosis.Exercise can regulate intestinal flora homeostasis,improve intestinal barrier function,promote the secretion of short-chain fatty acids and bile acids,down-regulate serum lipopolysaccharide level,reduce oxidative stress,and then inhibit osteocyte apoptosis,inhibit osteoclast differentiation,promote osteoblast differentiation,and regulate osteocyte nutrient metabolism to exert the potential of preventing and treating osteoporosis.

OBJECTIVE To systematically evaluate the therapeutic effect of acupuncture on geriatric insomnia.METHODS Randomized controlled trials(RCTs)on acupuncture in the treatment of senile insomnia were searched in CNKI,VIP,Wanfang,China Biomedical Database,PubMed,Web of science,Embase and Cochrane Library databases from inception dates to June 24,2024.Litera-ture was screened and data were extracted based on the inclusion and exclusion criteria.The literature quality was evaluated according to the risk of bias table recommended by the Cochrane Collaboration Handbook 5.1.0,and the outcome indicators were graded using the GRADE system for the quality of evidence.RevMan5.4 software was used to evaluate the quality of the included literature,and Sta-ta18.0 software was used to conduct Meta-analysis on the included literature.RESULTS A total of 18 studies involving 1399 pa-tients were included.Meta-analysis showed that:compared with the simple western medicine treatment,acupuncture in the treatment of senile insomnia patients could improve the clinical effective rate[RR=1.18,95%CI(1.13,1.24),P<0.001],reduce the total PSQI score[MD=-1.10,95%CI(-1.25,-0.96),P<0.001],daytime dysfunction[MD=-1.38,95%CI(-1.59,-1.16),P<0.001],sleep latency[MD=-0.66,95%CI(-0.86,-0.47),P<0.001],sleep duration[MD=-0.45,95%CI(-0.64,-0.25),P<0.001],sleep efficiency[MD=-0.69,95%CI(-0.89,-0.49),P<0.001],sleep disorder[MD=-1.24,95%CI(-1.47,-1.01),P<0.001],sleep quality[MD=-0.84,95%CI(-1.05,-0.64),P<0.001].GRADE classification showed that the clinical efficacy was advanced evidence;the adverse reactions were intermediate evidence;the total score of PSQI,daytime dysfunction,sleep latency,sleep efficien-cy,sleep quality and sleep disorder were low evidence;sleep time was extremely low evidence.CONCLUSION Acupuncture inter-vention in senile insomnia patients is superior to the control group in clinical efficiency and various PSQI scores.Acupuncture interven-tion is worthy of further promotion and use in clinical practice as the complementary and alternative therapy for the conventional western medication treatment of senile insomnia.However,the evidence levels of some outcome indicators are relatively low,and more high-quality RCTs with large sample sizes are still needed to increase the strength of evidence.

Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.

ObjectiveTo observe the effect of Youguiwan on the leptin/Janus kinase 2 （JAK2）/signal transducer and activator of transcription 3 （STAT3） signaling pathway in the lung tissue of the rat model of chronic obstructive pulmonary disease （COPD） due to kidney-Yang deficiency. MethodForty rats were modeled for COPD with the syndrome of kidney-Yang deficiency by intratracheal instillation of lipopolysaccharide on day 1 and day 14 and continuous fumigation for 6 weeks， during which hydrocortisone was injected intramuscularly at an interval of 3 days. The modeled rats were randomized into model， high- （11.7 g·kg^-1）， medium- （5.85 g·kg^-1）， and low-dose （2.93 g·kg^-1） Youguiwan， and aminophylline （0.054 g·kg^-1） group. In addition， 8 SD rats were set as the blank group. After the completion of modeling， the rats in each group were administrated with the corresponding drug by gavage for 28 consecutive days. After the last administration， samples were collected. A lung function analyzer was used to evaluate the lung function of rats. Enzyme-linked immunosorbent assay was employed to measure the levels of interleukin-17A （IL-17A）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in the bronchoalveolar lavage fluid （BALF）. Hematoxylin-eosin staining was employed to observe the pathological changes in the lung tissue， and Masson staining was employed to observe the deposition of blue collagen fibers around bronchi in the lung tissue and calculate the inflammation score. The immunofluorescence assay was employed to measure the protein content of collagen type Ⅰ （ColⅠ） and α-smooth muscle actin （α-SMA） in the bronchi. The protein and mRNA levels of leptin， IL-17A， JAK2， and STAT3 in the lung tissue were determined by Western blot and real-time fluorescence quantitative polymerase chain reaction， respectively. ResultCompared with the blank group， the model group showed decreased lung function （P<0.01）， elevated levels of IL-6， IL-17A， and TNF-α in the BALF （P<0.01）， and increased lung inflammation score， deposition of subcutaneous collagen fibers in the airway， and ColⅠ and α-SMA proteins （P<0.01）. Furthermore， the modeling up-regulated the proteins and mRNA levels of leptin， IL-17A， JAK2， and STAT3 in the lung tissue （P<0.01） and enhanced the phosphorylation of JAK2 and STAT3 （P<0.01）. Compared with the model group， high- and medium-dose Youguiwan improved the lung function， decreased the inflammation score， reduced collagen fiber deposition and ColⅠ and α-SMA proteins， lowered the levels of IL-6， IL-17A， and TNF-α in the BALF， down-regulated the mRNA and protein levels of leptin， JAK2， STAT3， and IL-17A， and weakened the phosphorylation of JAK2 and STAT3 （P<0.05， P<0.01）. The aminophylline group had higher IL-17A and TNF-α levels than the high-dose Youguiwan group， lower IL-17A level than the medium and low-dose Youguiwan groups， and lower TNF-α level than the low-dose Youguiwan group. Compared with the aminophylline group， the high- and medium-dose Youguiwan groups showed reduced deposition of collagen fibers and protein levels of ColⅠ and α-SMA around the bronchi in the lung tissue （P<0.05， P<0.01）， decreased inflammation score， and down-regulated protein and mRNA levels of leptin， JAK2， STAT3， and IL-17A in the lung tissue. ConclusionYouguiwan can prevent airway remodeling by inhibiting IL-17A to reduce inflammation and collagen deposition in COPD rats， which may be related to the inhibition of the leptin/JAK2/STAT3 signaling pathway.

ObjectiveTo observe the clinical efficacy and safety of Shugan Bushen Yulin Decoction （疏肝补肾毓麟汤， SBYD） in the treatment of asthenospermia and infertility with liver constraint and kidney deficiency. MethodsA multicenter， randomized， controlled clinical study was conducted in three hospitals in central China. Totally 95 patients with asthenospermia and infertility were controlled. According to random number table， the patients were divided into treatment group （47 cases） and control group （48 cases）. The control group was given vitamin E soft capsules （100 mg per time， twice daily） orally， and the treatment group was given SBYD （one dose daily， 30 min after breakfast and dinner， about 200 ml each time） orally. The course of treatment was 12 weeks in both groups. After the treatment， the sperm concentration， percentage of forward motile sperm （PR）， and percentage of total sperm activity， that is PR + percentage of non-progressively motile sperm （NP） were compared between groups， and the clinical efficacy was judged. Traditional Chinese medicine （TCM） syndrome score （inlcuding 6 single symptom scores and total symptoms score） and 21-item depression， anxiety， and stress scale （DASS-21） scores （including depression， anxiety and stress scores） were compared between the two groups before and after treatment. The patients were followed up for 6 months， and the pregnancy status of spouse between groups was compared. The occurrence of adverse events and vital signs during the trial were recorded for safety assessment. ResultsTwo cases in the treatment group and three cases in the control group dropped out. Finally， 45 cases in each group were included in the statistical analysis. The total effective rate was 86.67% （39/45） in the treatment group， significantly higher than 73.74% （33/45） in the control group （P＜0.05）. After treatment， PR and PR + NP significantly increased in both groups， and were much higher in the treatment group than in the control group （P＜0.05）. The scores of lumbar and knee soreness， emotional disturbance， cold sperm， chest and rib-side and lesser abdomen distension and pain， frequent sighing， and the total TCM syndrome score in the treatment group decreased after treatment （P＜0.05）； and except for cold sperm， the scores of other symptoms mentioned above as well as the total TCM syndrome score in the treatment group were lower than those in the control group （P＜0.05）. The scores of depression， anxiety and stress of DASS-21 in the treatment group decreased after treatment， and were lower than those in the control group （P＜0.05）. After 6 months of follow-up， the spouses of 5 patients in the treatment group and 3 patients in the control group got pregnant （P＞0.05）. No adverse events occurred in both groups during the treatment， and their vital signs were stable. ConclusionSBYD can obviously improve sperm vitality and effectively improve the clinical symptoms， anxiety and depression， and is safe in treating asthenospermia and infertility with liver constraint and kidney deficiency.

[Abstract] Blood transfusion is a common therapeutic measure with indispensable role in clinical medicine. However, there is a risk of transmitting diseases during blood transfusion, such as human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), etc. To reduce these risks and ensure blood transfusion safety, detection of disease markers in blood transfusion is particularly important. Biological sensing technology, with its advantages of high sensitivity, rapid response and portability, has broad application prospects in the detection of disease markers in blood transfusion. However, the biological sensing strategies for detection of disease markers in blood transfusion have not yet been systematically classified or fully discussed. Therefore, this paper first elucidates the common disease markers in blood transfusion and their importance. Then, it focuses on the application of biological sensors in the detection of disease markers in blood transfusion and discusses the challenges faced and the direction of future development in this field.
