ObjectiveTo analyze the epidemiological characteristics of 8 major respiratory pathogens in influenza-like illness (ILI) cases with acute respiratory infections at fever clinics in Huangpu District, Shanghai from 2015 to 2024, and to provide a scientific basis for the prevention and treatment of respiratory diseases. MethodsA retrospective study was conducted in Huangpu District. Individuals meeting the case definition of ILI from 2015 to 2024 was registered. Their nasopharyngeal swabs were collected for pathogen detection. A total of 8 respiratory viruses were tested, including Influenza A virus (Flu A), Influenza B virus (Flu B), adenovirus (ADV), enterovirus/human rhinovirus (EV/HRV), human parainfluenza virus (HPIV), human coronavirus (HCoV), respiratory syncytial virus (RSV), and human metapneumovirus (HMPV). ResultsFrom 2015 to 2019, a total of 344 ILI cases were tested, of which 192 out of 344 cases (55.81%) were tested positive for single respiratory pathogen. From 2023 to 2024, 1 557 ILI cases were tested, with 572 out of 1 557 cases (36.74%) being positive for single pathogen. From 2023 to 2024, the positive rate of single pathogen in ILI cases was significantly lower than that in 2015‒2019 (χ²=42.66, P<0.001). Specifically, the positive rate of Flu A (χ²=74.43, P<0.001) decreased, while that of HPIV (χ²=8.66, P=0.003) increased, both with statistically significant differences. According to the seasonal pattern, the epidemic intensity of Flu A decreased in summer, while that of HPIV increased in summer and autumn. Demographic results showed statistically significant differences in the positive rates of EV/HRV between genders (χ²=22.38, P<0.001), with males exhibiting a higher positive rate than females. No statistically significant differences were identified in the positive rates of single pathogen among different age groups (χ²=4.42, P=0.110). Nevertheless, statistically significant differences were noted when comparing the positive rates of EV/HRV, Flu A, Flu B and HPIV across different age groups (P<0.05). EV/HRV was more commonly detected in the 15‒<25 age group (10.93%), while Flu A and HPIV had the highest positive rates in the ≥60 age group (21.24% and 4.77%). Flu B had the highest positive rate in the 25‒<60 age group (11.26%). 52.63% of cases with co-infections occurred during winter, with the primary pathogens involved being EV/HRV (9 cases) and HCoV (6 cases). The most prevalent combination of co-infection was Flu A with EV/HRV. ConclusionThe prevalence of respiratory pathogens among ILI cases from 2023 to 2024 exhibited notable fluctuations compared to that from 2015 to 2019. Therefore, influenza surveillance should be strengthened, and attention should also be paid to the prevalence of respiratory pathogens such as HPIV. These findings have profound implications for future research, surveillance, vaccine planning, and public health policy making.

Objective To investigate the advantages and efficacy of traction with titanium clips in endoscopic submucosal dissection(ESD)for large laterally spreading tumor(LST)in rectum and sigmoid colon.Methods 67 patients with large sigmoid or rectal LST underwent ESD from January 2018 to June 2022 were analyzed retrospectively,including 32 patients in Group A and 35 patients in Group B.Group A was treated with clip-line traction and group B was treated with traditional ESD.The size of lesion,the total operation time,the submucosal dissection time,submucosal dissection rate,submucosal injection number,en bloc resection rate,R0 resection rate,curative resection rate and complications of the two groups were compared.Results LST-G-M was the most common type and villous adenoma was the main pathology in both groups.There were no differences in en bloc resection rate,R0 resection rate and incidence of complications between the two groups.The average size of group A was(13.6±8.4)cm2,significantly larger than that in group B(9.3±4.7)cm2,the total operation time was(42.3±10.3)min in group A,significantly shorter than that in group B(47.9±10.1)min,submucosal dissection time was(30.7±8.2)min in group A,significantly shorter than that in group B(36.1±7.6)min,submucosal injection number was(2.7±1.1)times in group A,significantly less than that in group B(3.5±1.2)times,submucosal dissection rate was(0.4±0.2)cm2/min in group A,significantly faster than that in group B(0.2±0.1)cm2/min,the differences were statistically significant(P<0.05).Conclusion Compared with traditional ESD,clip-line traction can provide a better surgical field and more effective dissection for large LST in rectum and sigmoid colon.

ObjectiveTo investigate the value of the serum levels of Clusterin and sphingosine 1-phosphate （S1P） in assessing the prognosis of sepsis patients with acute liver injury. MethodsA total of 127 sepsis patients with acute liver injury who were admitted to Lianyungang Hospital， Xuzhou Medical University， from March 2019 to May 2022 were enrolled， and according to their prognosis after 28 days of treatment， they were divided into death group with 35 patients and survival group with 92 patients. The independent-samples t test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between groups. A pearson correlation analysis was used to investigate the correlation. The prognostic value of serum Clusterin and S1P was analyzed by receiver operating characteristic curve. ResultsThere were significant differences between the two groups in the degree of liver injury， Acute Physiology and Chronic Health Evaluation Ⅱ （APACHEⅡ） score， Sequential Organ Failure Assessment （SOFA） score， the presence or absence of acute kidney injury， prothrombin time （PT）， international normalized ratio （INR）， Child-Pugh class， and C-reactive protein （all P<0.05）. The death group had significantly lower serum levels of Clusterin and S1P than the survival group （t=11.094 and 10.390， both P<0.05）. The patients with severe liver injury had significantly lower serum levels of Clusterin and S1P than those with mild or moderate liver injury （t=9.825 and 11.418， both P<0.05）. The multivariate regression analysis showed that the degree of liver injury （odds ratio ［OR］=1.260， 95% confidence interval ［CI］： 1.081 — 1.468， P<0.05）， APACHEII score （OR=1.031， 95%CI： 1.019 — 1.044， P<0.05）， SOFA score （OR=1.066， 95%CI： 1.039 — 1.094， P<0.05）， Clusterin （OR=0.899， 95%CI： 0.859 — 0.940， P<0.05）， and S1P （OR=0.824， 95%CI： 0.749 — 0.908， P<0.05） were independent risk factors for the prognosis of patients with sepsis. The ROC curve analysis showed that serum Clusterin and S1P used alone or in combination had an area under the ROC curve of 0.864， 0.861， and 0.949， respectively. Serum Clusterin and S1P were significantly negatively correlated with alanine aminotransferase， total bilirubin， PT， and INR in sepsis patients with acute liver injury （all P<0.05）. ConclusionThe sepsis patients with acute liver injury who died had significant reductions in serum Clusterin and S1P compared with those who survived， and the levels of Clusterin and S1P are closely associated with the degree of liver injury. The combination of Clusterin and S1P has a good value in predicting the prognosis of sepsis patients with acute liver injury and is expected to become a potential marker for predicting the prognosis of sepsis patients with acute liver injury.

Portal hypertension (PH) is a commonly seen complication of chronic liver disease and is a direct cause of decompensated cirrhosis. Early diagnosis of PH is essential for the treatment and prognosis of liver cirrhosis. Hepatic venous pressure gradient (HVPG) is the gold standard for the diagnosis of PH, but its invasiveness limits its use. At present, progress has been achieved on the noninvasive diagnostic techniques and of which the serological indicators are simple for use, including inflammatory mediators, vasoactive substances, extracellular matrix (ECM) components and their circulating degrading products. This article reviewed the advances in research on serological assessment of PH.
