OBJECTIVE To evaluate the efficacy and safety of amoxicillin combined with proton pump inhibitor （PPI） or potassium-competitive acid blocker （P-CAB） for Helicobacter pylori （Hp） eradication. METHODS Randomized controlled trial （RCTs） on amoxicillin combined with PPI or P-CAB for Hp eradication were retrieved from PubMed， Embase， the Cochrane Library， Web of Science， CNKI， Wanfang， and VIP data. The search time frame was from database inception to September 5， 2025. After literature screening， data extraction， and quality assessment， a network meta-analysis was performed using Stata 17.0 software. RESULTS A total of 12 RCTs involving 5 515 patients were included， encompassing 8 therapeutic regimens： PPI combined with high-dose amoxicillin for 14 days （TR1）， PPI combined with low-dose amoxicillin for 14 days （TR2）， P-CAB combined with high-dose amoxicillin for 7 days （TR3）， P-CAB combined with high-dose amoxicillin for 14 days （TR4）， P-CAB combined with high-dose amoxicillin for 10 days （TR5）， P-CAB combined with low-dose amoxicillin for 7 days （TR6）， P-CAB combined with low-dose amoxicillin for 14 days （TR7）， and P-CAB combined with low-dose amoxicillin for 10 days （TR8）. The network meta-analysis results showed that， in terms of intention-to-treat Hp eradication rates， the eradication rates of TR5 and TR4 were significantly higher than those of TR3， TR8， TR6 and TR1 （ P ＜0.05）. The surface under the cumulative ranking curve （SUCRA） values from highest to lowest were： TR4 （89.7%）＞TR5 （82.3%）＞TR7 （71.5%）＞ TR2 （48.6%）＞TR1 （43.9%）＞TR8 （28.7%）＞TR3 （22.7%）＞TR6 （12.6%）. Regarding safety， the incidence of adverse reactions in TR3 and TR5 was significantly lower than that in TR1 （ P ＜0.05）. The SUCRA values from highest to lowest were： TR1 （91.3%）＞TR4 （79.8%）＞TR5 （55.0%）＞TR7 （50.9%）＞TR8 （41.3%）＞TR2 （36.4%）＞TR3 （27.6%） ＞TR6 （17.7%）. CONCLUSIONS Although the regimen of P-CAB combined with high-dose amoxicillin for 14 days demonstrates the best efficacy， the combination of P-CAB with high-dose amoxicillin for 10 days exhibits a better balanced profile in terms of both efficacy and safety.

Obesity and its related metabolic diseases have become a major global public health threat, and its rising incidence significantly increases the risk of cardiovascular and cerebrovascular diseases, diabetes and other complications. Pancreatic lipase is a key enzyme that converts food-borne lipids into triglycerides and fatty acids, and the effective inhibition of its activity has become an important strategy for the treatment of obesity. This paper discusses the screening methods of pancreatic lipase inhibitors, and summarizes and reviews the basic principles, advantages and disadvantages and application status of traditional screening methods, modern new screening methods and virtual screening methods. In view of the problems faced by the screening methods of pancreatic lipase inhibitors, future research urgently needs to move towards a collaborative innovation path of multi-technology integration, intelligent screening and complex systematization of traditional Chinese medicine, so as to open up new research paradigms.

With the rapid advancement of hemodynamic indices and monitoring technologies, their classification methods and application processes have become increasingly complex. Currently, no unified standard hasbeen established, making it difficult to fully meet the clinical requirements for hemodynamic management. To assist in hemodynamic monitoring assessment and therapeutic decision-making in critically ill patients, the Critical Hemodynamic Therapy Collaborative Group, in conjunction with the Critical Ultrasound Study Group, has jointly developed the Standard for the Application of Hemodynamic Monitoring Techniques in Critical Care. The first part of this standard systematically categorizes hemodynamic indicators into flow indicators, pressure and its derivative indicators, and tissue perfusion indicators, while elaborating on the clinical application of each. The second part establishes a standardized clinical implementation pathway for hemodynamic monitoring. It proposes a tiered monitoring strategy-comprising basic, advanced, indication-specific, and special scenario monitoring-tailored to different clinical settings. It emphasizes the central role of critical care ultrasound across all levels of monitoring and establishes hemodynamic assessment standards for organs such as the brain, kidneys, and gastrointestinal tract. This standard aims to provide a unified framework for clinical practice, teaching, training, and research in critical care medicine, thereby promoting standardized development within the discipline.

To investigate the changes in peripheral blood immune cells before and after the onset of septic shock in patients with malignant tumors, and to analyze the relationship between these immune cells and patient prognosis.

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.

Based on the holistic view of "spleen-vessels-heart-spirit" system， this article explores the pathogenesis and progression of atrial fibrillation. It is proposed that the onset of atrial fibrillation is due to failure of the spleen to transport and disharmony of blood vessels； phlegm and blood stasis obstructing the collaterals and damage to the heart structure are the basis of its pathogenesis； the unclear mind and disorder of body and spirit are the causes of its progression. Based on the characteristics of pathological changes in different stages of the disease， it is proposed that early treatment should focus on restoring the middle jiao， clearing and promoting blood vessels， using modified Yigong Powder （异功散）； during the progression of the disease， treatment should remove blood stasis and phlegm， nourish heart and protect the pulse， using self-prescribed modified Mengshi Tongmai Decoction （礞石通脉汤）； meanwhile， calming mind and stabilizing palpitations， and regulating spirit should be sequentially incorporated， with self-prescribed Jiazao Ningmai Decoction （甲枣宁脉汤） or Shenying Dingji Decoction （参英定悸汤） and modified as appropriate. Clinical treatment should focus on the whole disease course of atrial fibrillation， implementing stage-based treatments to enable early intervention and holistic regulation.

Objective To analyze muscle activation intensity in patients with knee osteoarthritis(KOA)during physical activity by applying surface electromyography(sEMG),and investigate the impact of fear of movement on lower limb muscle function in patients with KOA.Methods A total of 30 patients with KOA were selected and categorized into a high-fear group(n=16)and a low-fear group(n=14)based on the TSK-17 scale(Tampa Scale for Kinesiophobia)scores,with 14 healthy individuals serving as the control group.A wireless sEMG system was used to record sEMG signals of different muscles.Test activities included walking at normal speed,stair ascent,and stair descent.Muscle activation was normalized to maximum voluntary contraction(MVC)by calculating the root mean square(RMS)of the EMG signals to compare muscle activation under different conditions.Correlation analyses were conducted to evaluate the relationship between muscle activation and TSK-17 scores.Results During normal walking,the healthy limb side of the high-fear group showed significantly greater activation in the rectus femoris(P＜0.05),vastus medialis(P＜0.01),and vastus lateralis(P＜0.01)compared to the affected limb side.Muscle activation of the healthy limb side was also elevated during stair ascent and stair descent in the high-fear group,with significant differences in the rectus femoris(P＜0.01),vastus medialis(P＜0.01),and vastus lateralis(P＜0.01).In the high-fear group,the affected/undominant and healthy/dominant limb side exhibited significantly increased activation in the rectus femoris(P＜0.05)during normal walking compared with the low-fear group and control group.The affected/undominant and healthy/dominant side also exhibited increased activation in the rectus femoris(P＜0.05)during stair ascent compared to the low-fear group and control group.There was a significant positive association between TSK-17 scores and rectus femoris activation on the healthy limb side during stair descent(r=0.95,P＜0.01).Conclusions Fear of movement has a significant impact on muscle activation patterns in patients with,particularly during stair descent,which places a greater functional demand on the lower limbs.Therefore,great attention should be paid to the intervention of psychological factors in KOA treatment,so as to comprehensively improve both motor function and life quality of the patients.

Objective:To study the resistance of Aedes albopictus to commonly used insecticides in Hangzhou, and to investigate the polymorphism distribution characteristics of voltage-gated sodium channel (VGSC) and acetylcholinesterase (AchE) 1 (Ace-1) genes in Aedes albopictus in the region, providing a scientific basis for control of Aedes albopictus in Hangzhou. Methods:From May to June 2023, Aedes albopictus larvae and pupae were collected from residential areas across divided different urban areas by directions in Hangzhou. They were reared in the laboratory, and their resistance to malathion, propoxur, pyrethroid insecticides (permethrin, deltamethrin, and beta-cypermethrin) was evaluated using the World Health Organization-recommended adult mosquito contact tube method. The 24 h mortality rates of adult mosquito of 98% - 100% was susceptible, 80% - < 98% was suspected resistance, < 80% was resistant. Genomic DNA was extracted from adult Aedes albopictus, and mutations in the VGSC and Ace-1 genes were detected through PCR amplification and Sanger sequencing. Results:The 24 h mortality rates of adult Aedes albopictus exposed to 0.5% malathion, 0.05% propoxur, 0.4% permethrin, 0.03% deltamethrin, and 0.08% beta-cypermethrin in Hangzhou were 100% (75/75), 96.00% (72/75), 41.43% (29/70), 17.33% (13/75), and 32.86% (23/70), respectively. A total of 146 surviving Aedes albopictus were tested for VGSC gene mutations at diagnostic doses of pyrethroid insecticides. Among them, 6 Aedes albopictus (4.11%) had a gene mutation at position V1016, and 146 Aedes albopictus (100%) had a gene mutation at position F1534. A total of 63 Aedes albopictus that died at diagnostic doses of pyrethroid insecticides were analyzed for VGSC gene mutations. No gene mutation was detected at position V1016, while 63 Aedes albopictus (100%) had a gene mutation at position F1534. One non synonymous mutation was detected at position V1016 of the VGSC gene, which was a heterozygous mutation of V1016V to V1016V/G. Two non synonymous mutations were detected at position F1534 of the VGSC gene, namely F1534F to F1534S or a F1534F/S heterozygous mutation. No Ace-1 gene mutation was detected in all Aedes albopictus exposed to 0.05% propoxur ( n = 75). Conclusions:The Aedes albopictus in Hangzhou has developed resistance to permethrin, deltamethrin, and beta-cypermethrin. It shows suspected resistance to propoxur and sensitivity to malathion. Moreover, a high frequency of mutations in the VGSC gene has been observed in these mosquitoes. It is crucial to enhance resistance monitoring in Aedes albopictus populations in Hangzhou and to implement the rational rotation of chemical insecticides to slow down the progress of drug resistance.

Objective:To investigate the value of T helper 17 cells（Th17）/regulatory T cells（Treg）imbalance in the evaluation of intravenous immunoglobulin（IVIG）resistance in children with Kawasaki disease and Kobayashi score≤4.Methods:A total of 78 children with Kawasaki disease and Kobayashi score ≤ 4 admitted to Hunan Children's Hospital from January 2020 to December 2023 were prospectively selected as the study subjects，all of whom received IVIG treatment.In the acute phase，the proportion of Th17 cells and Treg cells was detected.Children were divided into IVIG sensitive group and IVIG resistance group based on their responsiveness to IVIG treatment.Baseline data of children with different IVIG treatment responsiveness，acute Th17 cell inflammatory factors [interleukin（IL）-17，IL-21，tumor necrosis factor-α（TNF-α）]，Treg cell inflammatory factors [IL-10，IL-35，transforming growth factor-β（TGF-β）] levels，and Th17/Treg values were compared.The correlation between Th17/Treg values and IVIG resistance in children with Kawasaki disease was analyzed using a restricted cubic spline model（RCS）.According to the threshold of correlation between Th17/Treg values obtained from RCS analysis and drug resistance in children，Th17/Treg was grouped，with a focus on analyzing the predictive value and clinical benefits of Th17/Treg values for IVIG resistance in children with Kawasaki disease.Results:Among the 78 children with Kawasaki disease，16 were resistant to IVIG treatment，accounting for 20.51%.The levels of C-reactive protein（CRP）,IL-17,and Th17/Treg in the acute phase of children in the IVIG resistance group were higher than those in the IVIG sensitive group，while the levels of IL-10 were lower than those in the IVIG sensitive group（ P<0.05）.RCS analysis showed that there was a non-linear dose-response relationship between IVIG resistance and acute Th17/Treg values in children with Kawasaki disease（ P<0.05）.When the acute Th17/Treg value was greater than 1.05，the risk of IVIG resistance in children with Kawasaki disease increased with the increase in indicator levels.The levels of CRP and IL-17 in the acute phase of children with Th17/Treg>1.05 were higher than those in the Th17/Treg < 1.05 group，while IL-10 levels were lower than those in the Th17/Treg<1.05 group.The proportion of children resistant to IVIG treatment was higher than that in the Th17/Treg<1.05 group（ P<0.05）.Multivariate Logistic regression analysis showed that CRP，IL-17，IL-10，and Th17/Treg were the influencing factors of IVIG resistance in children with Kawasaki disease（ P<0.05）.It was found through a nomogram that the C-index of the acute phase Th17/Treg values and their secretion of inflammatory factors in children with Kawasaki disease and Kobayashi score ≤ 4，as well as other major indicators，predicted the risk of IVIG resistance.The C-index was 0.975（95% CI 0.944-1.000），indicating good discrimination.When drawing the decision curve，it was found that compared to using each indicator separately，the Th17/Treg value and its secreted inflammatory factors in the acute phase assisted other major indicators in drawing the decision curve with a higher net benefit rate，with a maximum net benefit rate of 0.205. Conclusion:IVIG resistance in children with Kawasaki disease and Kobayashi score≤4 is related to Th17/Treg imbalance.When the Th17/Treg value in the acute phase of the disease is greater than 1.05，the risk of IVIG resistance is higher.The inflammatory factors IL-17 and IL-10 secreted by the two can assist other known indicators related to IVIG resistance in Kawasaki disease patients，improving the accuracy of predicting resistance risk.

Chronic pancreatitis is a chronic inflammatory disease characterized by progre-ssive fibrosis of pancreatic tissue. Its pathological features primarily include parenchymal fibrosis, intraductal stone formation or calcification deposits, as well as segmental stenosis and dilation of the pancreatic duct. Prolonged chronic inflammatory stimulation not only leads to progressive pancreatic dysfunction but may also trigger the formation of pancreatic pseudocysts and even malignant transformation. In the comprehensive treatment of chronic pancreatitis, the core clinical goals are the removal of pancreatic duct stones, restoration of unobstructed pancreatic duct drainage, and preservation of residual pancreatic function. Traditional treatment strategies have been based on the principle of progressive intervention and early surgical management. In recent years, with advancements in extracorporeal shock wave lithotripsy, the application of new techniques such as endoscopic retrograde cholangiopancreatography combined with laser lithotripsy under direct cholan-gioscopic visualization, and improvements in pancreas-preserving surgical approaches, the debate over the superiority of progressive intervention versus early surgical treatment has intensified. Against this backdrop, the treatment mode of Xi′an Jiaotong University Pancreatic Disease Center (hereinafter referred to as "Western Pancreas") has emerged, emphasizing a personalized, multimodal treatment strategy based on different types of pancreatic duct stones. The treatment mode of "Western Pancreas" integrates lithotripsy, endoscopic treatment, and surgical interventions to optimize patient outcomes. By conducting a comprehensive analysis of domestic and international pancreatic duct stone classi-fication systems and drawing from our team′s clinical experience in managing over a thousand cases of chronic pancreatitis, the authors have further refined and proposed a classification system for pancreatic duct stones under the treatment mode of "Western Pancreas". This refinement aims to enhance the overall diagnostic and therapeutic standards for chronic pancreatitis.
