Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.

Objective To investigate the prevalence status and influencing factors of metabolic syndrome (MS) in adult patients with hypopituitarism (HP) during hospitalization. Methods The data of adult HP patients who received treatment in the hospital were collected from March 2021 to March 2024. The prevalence status of MS in adult HP patients was counted, and logistic regression analysis was adopted to analyze the influencing factors of MS in adult HP patients. Results Among the 308 adult HP patients in this study, 121 cases developed MS and 187 cases did not develop MS, and they were included in the MS group (n=148) and the non-MS group (n=232). The incidence of MS in adult HP patients was 38.95% (148/380). Compared with the non-MS group, the levels of high-density lipoprotein cholesterol, serum total cholesterol and low-density lipoprotein cholesterol in the MS group were higher, the waist circumference was larger, and the growth hormone was lower (P<0.05). After logistic regression analysis, it was found that high-density lipoprotein cholesterol (OR=1.069, 95%CI: 1.010-1.132, P=0.021), total serum cholesterol (OR=1.065, 95%CI: 1.014-1.119, P=0.012), low-density lipoprotein cholesterol (OR=1.055, 95%CI: 1.005-1.108, P=0.031), waist circumference (OR=1.063, 95%CI: 1.006-1.123, P=0.030) and growth hormone (OR=1.077, 95%CI: 1.019-1.138, P=0.009) could independently affect the occurrence of MS in adult HP patients (P<0.05). Conclusion Adult HP patients during hospitalization are often complicated with MS. High-density lipoprotein cholesterol, serum total cholesterol, low-density lipoprotein cholesterol, waist circumference, and growth hormone are factors affecting the occurrence of MS in adult HP patients.

Objective: To investigate the status of overweight and obesity among primary and middle school students in Yuyao City, Zhejiang Province, so as to provide the basis for formulating weight management strategies for students. Methods: A census was conducted to investigate 72 primary schools and 23 middle schools students in Yuyao City in 2024, and data such as gender and age were collected through questionnaire surveys. Height and weight were measured to calculate the body mass index (BMI). Based on the BMI thresholds for different gender and age groups, overweight and obesity were determined. Results: Totally 75 082 individuals were surveyed, including 40 435 boys and 34 647 girls. Among them, 55 172 were primary school students and 19 910 were middle school students. A total of 8 677 overweight and 7 042 obese individuals were identified, with detection rates of 11.56% and 9.38%, respectively. The detection rates of overweight and obesity in boys were higher than in girls (14.01% vs. 8.69%, 11.58% vs. 6.81%, both P<0.05). The detection rate of obesity among students in rural schools was higher than students in urban schools (10.12% vs. 8.18%, P<0.05). The detection rates of overweight and obesity of students with non-local household registration were higher than students with local household registration (12.04% vs. 10.77%, 10.44% vs. 7.64%, both P<0.05). The detection rate of overweight showed an upward trend with age (P<0.05), while no significant age-related trend was observed for obesity (P>0.05). Conclusions The detection rates of overweight and obesity were notably high among primary and middle school students in Yuyao City. Boys, students in rural schools, students with non-local household registration, and older students are the key population.

Objectives To explore the feasibility of temporary veno-venous extracorporeal membrane oxygenation(VV-ECMO)technology for early on-site treatment,through establishing an animal model of severe blast lung injury in goats by free-field chemical explosion experiments in high-altitude regions.Methods A total of 16 adult goats were selected,and divided into the control group and the treatment group according to the random number table method,with 8 goats in each group.A model of severe blast lung injury was established at an altitude of 4 600 meters above sea level,then the goats in the control group were given respiratory support and the goats in the treatment group were given temporary VV-ECMO treatment.The survival status of the goats 15 minutes after injury was recorded,the vital signs[including body temperature,respiration rate,heart rate,and mean arterial pressure(MAP)]and arterial blood gas analysis indicators[including pH,arterial partial pressure of oxygen(PO2),arterial partial pressure of carbon dioxide(PCO2),oxygen saturation(SaO2),lactate(LAC),calcium(Ca2+),hematocrit(HCT),and hemoglobin(Hb)]before injury and 1 hour,2 hours,3 hours after injury were compared in the two groups.The post-mortem examination was performed on all dead goats and sacrificed goats after treatment,the severity of lung injury was assessed by organ injury scaling(OIS),and the lung injury score was evaluated by abbreviated injury scale(AIS).The wet-to-dry weight ratio(W/D)and lung coefficient were calculated.Results Within 15 minutes after the explosion,4 goats in the control group died and 4 goats survived;and 5 goats in the treatment group died and 3 goats survived.There was no statistically significant difference in the body temperature,respiration rate,heart rate,or MAP before and after injury between the two groups(P>0.05).The PaO2 and SaO2 1 hour,2 hours,and 3 hours after injury in the treatment group were superior than those in the control group(P<0.05),the Ca2+ 2 hours after injury was significantly higher than that in the control group(P<0.05),and there was no statistically significant difference in the pH,PCO2,LAC,HCT or Hb at different time points after injury between the two groups(P>0.05).There was no statistically significant difference in the OIS,AIS or lung coefficient between the two groups(P>0.05),but the W/D of the lung tissue in the control group was lower than that in the treatment group(P<0.05).Conclusion We have established a novel,feasible,and stable treatment effect temporary VV-ECMO animal treatment strategy for the first time in the high-altitude regions,which can provide animal experiment evidence for the early on-site VV-ECMO treatment of severe blast lung injury in high-altitude regions.

Objective To investigate the efficacy of different approaches for screw internal fixation in the treatment of posterior ankle fractures in trimalleolar fracture,and the complications was analyzed.Methods A prospective study was conducted on 80 patients with Haraguchi type Ⅰ posterior ankle fracture who admitted to our hospital from May 2019 to October 2020,they were randomly divided into group A and group B according to a random number table method,with 40 cases in each group.Patients in group A were treated with percutaneous anterior to posterior screw internal fixation for posterior ankle fractures,while patients in group B were treated with percutaneous posterolateral approach limited exposure and reduction screw internal fixation for posterior ankle fractures.The surgical indicators,postoperative recovery,American Orthopaedic Foot and Ankle Society(AOFAS)score,ROM score of ankle joint at the last follow-up,postoperative evaluation,and postoperative complications of patients between the two groups were compared.Results There was no statistically significant difference in operation time,complete weight-bearing time,or fracture healing time of patients between the two groups(P>0.05),but the fluoroscopy times of patients in group A was less than that in group B,the intraoperative bleeding volume and fibular incision length were less/shorter than those in group B(P<0.05).The AOFAS scores of patients 6 months after surgery and at the last follow-up in both groups increased compared with those 3 months after surgery,and the AOFAS scores at the last follow-up were higher than those 6 months after surgery,the differences were statistically significant(P<0.05).The AOFAS scores of patients 6 months after surgery and at the last follow-up in group B were higher than those in group A(P<0.05).There was no statistically significant difference in ROM score of ankle joints(plantar flexion,valgus,varus,dorsiflexion)of patients between the two groups at the last follow-up(P>0.05).There was no statistically significant difference in poor screw position,degree of pain,walking condition,or squatting condition of patients between the two groups(P>0.05).However,the reduction quality of posterior ankle fractures of patients in group B was better than that in group A(Z=4.248,P<0.05).No complications such as loosening of internal fixation or loss of fracture reduction occurred in both groups.Conclusion Both percutaneous anterior to posterior screw internal fixation and percutaneous posterolateral approach limited exposure and reduction screw internal fixation have good efficacy for posterior ankle fractures in trimalleolar fracture,with high safty.The former has more fluoroscopy times and less intraoperative bleeding,while the latter is better in improving ankle joint function and fracture reduction.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

The aim of this study was to investigate the impact of overexpressing 70-kD heat shock pro-teins(Hsp70)on glycolysis in C2C12 cells during myogenesis and adipogenesis.Using C2C12 cells as the research material,adenovirus was used to overexpress the Hsp70 gene,and changes in the expression of glycolytic genes were detected using fluorescence quantitative PCR and Western blotting techniques.The study indicated that during C2C12 cell myogenic differentiation,the expression trend of the Hsp70 gene was consistent with that of Gsk3β,Pkm,Prkag3,Pfkm,and Hk-2 genes,suggesting a relationship between Hsp70 and the glycolytic pathway during myogenic differentiation.Overexpression of Hsp70 in the later stages of myogenic differentiation significantly upregulated the expression of Gsk3β,Pkm,Prk-ag3,and Pfkm genes(P＜0.05),with no significant impact on Hk-2 gene expression(P＞0.05).Dur-ing C2C12 cell adipogenic induction,the expression trend of the Hsp70 gene was similar to that of Gsk3β,Pkm,Prkag3,Pfkm,and Hk-2 genes,indicating a relationship between Hsp70 and the glycolytic path-way during adipogenic induction.Following Hsp70 overexpression,in the later stages of adipogenic in-duction,the number of lipid droplets was significantly higher compared to the control group,with a sig-nificant upregulation of Gsk3β,Pkm,Prkag3,and Pfkm gene expression(P＜0.05),while Hk-2 gene expression was not significantly affected(P＞0.05).In conclusion,Hsp70 in C2C12 cells in myogenic and adipogenic states promoted the breakdown of glycogen into 6-phospho-glucose,thereby enhancing the glycolytic pathway,providing insights into the functional role of the Hsp70 gene in glycolysis in C2C12 cells.

Bamboo leaf flavonoids(BLF)are compounds extracted from bamboo leaves,possessing properties including antioxidant,antimicrobial and anti-inflammatory properties.This study aimed to investigate the effects of BLF on liver damage,antioxidant function,and related gene expression in rats induced by diquat(DQ).Thirty-two 5-week-old male Sprague-Dawley(SD)rats were randomly divided into four experimental groups:the control group(Con),1 000 mg/kg BLF group(BLF),DQ stress group(DQ),and 1 000 mg/kg BLF+DQ stress group(BLF-DQ).The results showed that compared to the Con,the DQ group exhibited significantly decreased serum AST lev-els(P＜0.05),as well as decreased levels of T-AOC,GPX,SOD,and CAT in the liver(P＜0.05),and increased MDA levels in rats(P＜0.05).Additionally,the gene expression levels of HO-1,GPX,CAT,SOD1,and Nrf2 in the liver were significantly reduced(P＜0.05).In contrast,1 000 mg/kg BLF significantly decreased serum AST and ALT levels(P＜0.05),increased levels of T-AOC,GPX,CAT,and SOD in liver(P＜0.05),and significantly increased gene expression of HO-1,GPX,CAT,SOD1,Nrf2,and NQO1(P＜0.05).Compared to the DQ group,BLF-DQ significant-ly decreased liver index(P＜0.05),reduced serum AST and ALT levels(P＜0.05),increased lev-els of CAT,GPX,and T-AOC in liver(P＜0.05),decreased MDA levels(P＜0.05),and signifi-cantly upregulated gene expression levels of HO-1,GPX,CAT,SOD1,and Nrf2(P＜0.05).These findings indicated that BLF alleviate liver damage caused by DQ stress in rats,improve liver an-tioxidant function inhibition,activate the Nrf2 signaling pathway and PINK/Parkin mitophagy-re-lated gene expression.
