Objective To analyze the influenza-like illness (ILI) data in Ordos City from 2017 to 2023 and conduct nucleic acid detection of the virus to understand the local influenza epidemic situation, and to provide a reliable basis for influenza prevention and control in the city. Methods Real-time quantitative polymerase chain reaction (qPCR) was used to identify virus subtypes in ILI throat swab samples. Comparisons of positive rates were conducted using the chi-square test, with a significance level of α=0.05. Results From 2017 to 2023, a total of 3,283,434 outpatient and emergency visits were recorded at the Ordos City Central Hospital, including 74,159 ILI cases, with an ILI proportion of 2.26%. The majority of ILI cases (74.43%) occurred in children aged 0~14 years old. The overall positive rate of influenza virus nucleic acid detection was 10.87%, with the highest proportion being subtype A (seasonal H3) at 43.03%. The highest detection rate was observed in the 5~14 years age group, with statistically significant differences in positive rates across age groups (χ²=155.638, P<0.001). Influenza peaks occurred mainly from November to March of the following year. From January to April, three types of influenza were prevalent alternately or mixed, while from October to December, subtype A (seasonal H3) predominated. Positive rates varied significantly across months (χ²=250.923, P<0.001). The temporal trends of ILI proportions and PCR-positive rates were consistent. Conclusion Influenza in Ordos City exhibits distinct seasonal and age distribution characteristics, with alternating or mixed circulation of three virus types. Continued efforts are needed to strengthen influenza surveillance, especially the prevention and control of influenza in infants and adolescents.

Objective To analyze the characteristics of viral hepatitis mortality and life loss among residents in Pudong New Area from 2003 to 2023, and to provide a basis for related prevention and control work. Methods Viral hepatitis mortality data were obtained from the Pudong New Area mortality monitoring system. The crude mortality rate (CMR), standardized mortality rate (SMR), potential years of life lost (PYLL), average years of life lost (AYLL), and standardized potential years of life lost (SPYLL) were calculated to analyze viral hepatitis deaths. The average annual change (AAPC) and annual percentage change (APC) of the mortality rate were calculated by Joinpoint regression analysis to analyze the trend of mortality. Results The CMR and SMR of viral hepatitis among residents in Pudong New Area from 2003 to 2023 were 3.89/100000 and 1.98/100000, respectively. Both CMR and SMR of viral hepatitis showed a decreasing trend over time (CMR:APC=-5.476, t=-13.581, P<0.001; SMR:APC=- 7.624, t= -21.253, P<0.001). The CMR for males was 4.75/100000 and the SMR for males was 2.65/100000; the CMR for females was 3.04/100000 and the SMR for females was 1.32/100000, with a higher mortality rate for males than for females（Z_CME=12.094，P<0.001; Z_SMR=-14.718，P<0.001). Deaths were concentrated in the age groups of 45-64 years old and 65 years old and above, accounting for 91.62% of the total deaths. The PYLL of deaths due to viral hepatitis among residents in Pudong New Area from 2003 to 2023 was 26912 person-years, with a PYLLR of 0.45% and an AYLL of 8.88 years per person. Conclusion The mortality rate of viral hepatitis among the residents of Pudong New Area in 2003-2023 shows a decreasing trend over time. The mortality rate of males is higher than that of females, and the deaths of middle-aged and elderly people account for a large proportion of the total deaths. Chronic hepatitis B is the main cause of death.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

Objective To explore the clinical efficacy of robot-assisted coronary artery bypass grafting through a small incision in the left intercostal space in the treatment of multivessel coronary disease. Methods A retrospective analysis was conducted on the clinical data of patients who underwent coronary artery bypass grafting through a small incision in the left intercostal space at Central China Fuwai Hospital of Zhengzhou University from January 1, 2023 to October 15, 2024. Patients were divided into a robotic group and a minimally invasive group based on whether the surgery was assisted by the Da Vinci robot. Results A total of 81 patients were included, with 57 in the minimally invasive group, including 41 males and 16 females, with a median age of 65.0 (57.5, 69.5) years; and 24 in the robotic group, including 17 males and 7 females, with a median age of 61.0 (56.0, 69.0) years. There was no statistically significant difference in baseline data between the two groups (P>0.05). The robotic group had less intraoperative bleeding [300 (200, 438) mL vs. 500 (375, 600) mL, P=0.006], shorter postoperative mechanical ventilation time [15.0 (13.3, 23.5) h vs. 22.0 (15.5, 39.5) h, P=0.037], and lower incidence of postoperative pain [8 (33.3%) vs. 33 (57.9%), P=0.043]. The hospitalization cost in the robotic group was higher than that in the minimally invasive group [130491 (123298, 135691) yuan vs. 123892 (115543, 133449) yuan, P=0.023]. There was no statistical difference in postoperative laboratory indicators between the two groups (P>0.05). There was also no statistical difference in the duration of surgery, postoperative 24 h drainage volume, ICU stay time, postoperative hospital stay or incidences of perioperative compications including pleural effusion, transfusion, new-onset atrial fibrillation, acute kidney injury, non-union of incision, major cardiovascular and cerebrovascular adverse events, and reoperation between the two groups (P>0.05). Conclusion Compared with the minimally invasive group, the robotic group shows satisfactory efficacy and can effectively reduce postoperative pain and intraoperative bleeding, and shorten postoperative mechanical ventilation time.

Objective To explore the action mechanism of dehydrocostus lactone(DHL)on renal interstitial fibrosis(RIF)in rats with unilateral ureteral obstruction(UUO).Methods Forty-four male SD rats were randomly divided into four groups:the sham surgery group(Sham group),the pure drug intervention group(Sham+DHL group),the experimental group(UUO+Vehicle group)and the DHL treatment group(UUO+DHL group),with 11 rats in each group.The rats underwent sham surgery,sham surgery+DHL[10 mg/(kg·d)],UUO modeling+the same volume of solvent and UUO modeling+DHL[10 mg/(kg·d)],respectively.After surgery,DHL or the same volume of solvent was administered by gavage for 14 days starting from day 2 post-surgery.Hematoxylin-eosin(HE)and Masson staining were used to observe the pathological changes in renal tissue.Immunohistochemical staining was performed to detect the expression levels of collagen I,collagen III and α-smooth muscle actin(α-SMA).Western blotting was used to detect the protein levels of the transforming growth factor(TGF)-β1/Smad2/3 pathway.Results Compared with the UUO+Vehicle group,DHL treatment alleviated renal interstitial pathological damage,reduced collagen fiber deposition,and decreased the expression of collagen I,collagen III and α-SMA.It also inhibited the expression of TGF-β1 and Smad2/3 proteins.Conclusions DHL mitigates RIF in rats by inhibiting the TGF-β1/Smad2/3 pathway,providing a new strategy for the treatment of chronic kidney disease.

BACKGROUND:Various clinical strategies for the treatment of tendinopathy have good short-term effects but poor long-term effects,and some studies have proven that mitochondria are closely related to the occurrence and development of tendinopathy.However,the relationship between mitochondria and tendinopathy and mitochondria-targeting therapeutic strategies for tendinopathy have not been summarized so far,which is not good for specialists and scholars in related fields to understand the recent research situation.OBJECTIVE:To review the existing clinical or preclinical original studies,in order to summarize the relationship between mitochondrial dysfunction and tendinopathy and the mitochondria-targeting methods for the treatment of tendinopathy,and to provide certain prospects for the evaluation and management of mitochondria in tendinopathy in the future.METHODS:The relevant literatures in PubMed,Web of Science,CNKI,WanFang and VIP databases were searched.The search time was from January 2009 to March 2024,and the search terms were"tendinopathy,tendon injuries,tendon,tendons,mitochondria,mitochondria dysfunction,mitochondria disease"both in English and Chinese.According to the exclusion and inclusion criteria,62 articles were finally included for review and analysis.RESULTS AND CONCLUSION:(1)In clinical tendinopathy patients or tendinopathy models,mitochondrial dysfunction is common,mainly represented by excessive production of reactive oxygen species,decreased activity of superoxide dismutase,ridge clutter and decreased number of mitochondria,which indicates that mitochondrial dysfunction will occur due to tendon injury,thus further worsening tendinopathy and forming a vicious cycle.(2)When the tendon has not been injured or tendinopathy has not yet occurred,the mitochondrial function will be affected by various internal and external factors,resulting in tendinopathy.This indicates that the normal tendon will be damaged,lesioned or even ruptured due to the abnormal function of the mitochondria.(3)Mechanical tensile stress,advanced glycosylation end products,aging and other internal and external factors are the main causes of mitochondrial dysfunction,and these factors will damage and weaken the biological activity and mechanical properties of normal tendons through molecular mechanisms such as apoptosis,inflammation and respiratory chain damage,and thereby induce tendinopathy.(4)According to molecular mechanisms,mitochondria-targeting therapies mainly include mitochondrial transfer/transplantation,transplantation,targeted antioxidants,etc.(5)This review mainly aims at clinical patients with tendinopathy or animal models with similar modeling methods,providing a reliable idea for clinical exploration of the pathogenesis of tendinopathy and targeted therapies for tendinopathy.However,the disadvantage is that the included studies are mainly animal experiments,and there is a lack of more clinical trials for verification.

Objective To explore the protective effect and mechanism of miR-202-5p on acute respiratory distress syndrome(ARDS)-induced lung injury in neonatal rats.Methods Sixty newborn SD rats were randomly divided into six groups:the control group(intraperi-toneal injection of normal saline by tail vein),ARDS group(ARDS model established via intraperitoneal injection of 4 mg/kg lipopolysac-charide by tail vein),ARDS+miR-NC group(ARDS rats receiving 2 mg/kg miR-NC via tail vein injection once every 4 h,with intervention for 12 h),ARDS+miR-202-5p group(ARDS rats receiving 2 mg/kg miR-202-5p via tail vein injection once every 4 h,with intervention for 12 h),ARDS+miR-202-5p+ov-NC group,and ARDS+miR-202-5p+ov-ROCK1 group(ARDS rats receiving 2 mg/kg miR-202-5p once every 4 h,with intervention for 12 h;with 6 × 108 plaque-forming units control or overexpression ROCK adenovirus administered via tail vein 3 days before lipopolysaccharide injection).Real-time quantitative PCR was employed to measure miR-202-5p and ROCK1 mRNA expression in rat lung tissue.Hematoxylin and eosin staining was performed to assess pathological lung injury.The lung tissue wet-to-dry weight ratio was determined to evaluate pulmonary edema.Western blotting was utilized to analyze ROCK1,Toll-like receptor 4(TLR4),phosphorylated-nuclear factor κB(p-NF-κB)p65,and phosphorylated-inhibitor of nuclear factor-κBα(p-IκBα)protein expression in lung tissue.The interaction between miR-202-5p and ROCK1 was validated using dual-luciferase reporter gene experiments.Results miR-202-5p expression was significantly down-regulated in ARDS rat lung tissue,while overexpression of miR-202-5p ameliorated pathological injury and pulmonary edema in ARDS rats.ROCK1 mRNA was upregulated in ARDS rat lung tissue;however,overexpression of miR-202-5p decreased the expression of ROCK1 in lung tissue of ARDS rats,while overexpression of ROCK1 reversed the protective effect of overexpression of miR-202-5p on lung injury in ARDS rats.Furthermore,miR-202-5p overexpression suppressed TLR4,p-NF-κB p65,and p-IκBα protein expression in ARDS rat lung tissue,an effect that was reversed by ROCK1 overexpression.Dual-luciferase reporter gene experiments confirmed that miR-202-5p directly targets ROCK1 mRNA 3'UTR.Conclusion miR-202-5p ameliorates ARDS-in-duced lung injury in neonatal rats through targeted suppression of ROCK1 expression,with the underlying mechanism potentially involving inhibition of ROCK1-mediated TLR4/NF-κB signaling pathway activation.
