OBJECTIVE To explore the risk factors for severe influenza patients in Fuzhou,and to provide reference for the prevention and control of severe influenza.METHODS Information on 412 patients with severe influenza in Fuzhou City with onset dates from Jan.2023 to Jan.2025 was collected from the China Influenza Surveillance In-formation System and the China Disease Prevention and Control Information System.The severe patients were matched 1∶1 with non-severe patients based on gender and age±3 years of the severe patients.Basic infor-mation,vaccination history,clinical symptoms,types of infecting viruses and medical history of both groups of patients were collected to summarize the risk factors for severe illness progression in influenza patients.RESULTS The proportions of obesity,retired personnel,children or students,unemployed individuals and smokers in the se-vere group were all higher than those in the non-severe group,while the vaccination rate(6.07％)was lower than that of the non-severe group(16.50％)(P＜0.001).The proportions of typical symptoms of shortness of breath/dyspnea and altered mental status/convulsions in the severe group were 23.30％and 21.60％,respectively,which were higher than those in the non-severe group(P＜0.001).The proportions of individuals with a history of chro-nic respiratory diseases and cancer/tumors in the severe group were 26.70％and 19.90％,respectively,which were higher than those in the non-severe group(P＜0.001).The proportion of influenza A(H1 N1)in the severe group(58.50％)was higher than that in the non-severe group(39.32％)(P＜0.001).Retired personnel,children or students and unemployed individuals were high-risk groups for the severe influenza,while farmers were a low-risk group.Obesity(OR=1.966),unvaccination(OR=3.738),smoking(OR=1.787),typical symptoms of shortness of breath/dyspnea(OR=3.305),altered mental status/convulsions(OR=4.099),history of chronic respiratory diseases(OR=4.820)and history of cancer/tumors(OR=3.269)and infection with influenza A(H1N1)(OR=6.422)and influenza A(H3N2)(OR=4.441)were risk factors for the severe influenza(P＜0.05).The recovery time in the severe group was 21(6,33)days,which was longer than that in the non-severe group(P＜0.001).CONCLUSIONS Obesity,unvaccination,smoking,typical symptoms of shortness of breath/dyspnea,altered mental status/convulsions,history of chronic respiratory diseases and history of cancer/tumors and infection with influenza A(H1N1)and influenza A(H3N2)are risk factors for severe influenza patients.It is necessary to strengthen influenza prevention and control among the elderly and children,enhance health edu-cation,and continuously promote influenza vaccination among key populations.

Objective:To analyze the effect of rapid division of left Glisson pedicle and Arantius tube plane in laparoscopic anatomical left hemihepatectomy (LALH).Methods:Clinical data of 25 patients (15 with intrahepatic bile duct calculus and 10 with liver tumor) undergoing LALH in the Department of Hepatobiliary and Pancreatic Surgery, Jiangyin Hospital Affiliated to Nantong University from June 2020 to November 2024 were retrospectively analyzed, including 14 males and 11 females, aged (66.6±11.9) years. Among the patients, 15 received LALH with rapid division of left Glisson pedicle and Arantius tube plane in " one-clamp" fashion, and the others received LALH after traditional dissection of left Glisson pedicle. Age, sex, body mass index, time of left Glisson pedicle dissection, whether the MHV exposure, the time of liver transection, whether MHV and its important branches or bile duct injury occurred, intraoperative blood loss, the incidence of postoperative biliary leakage, the time of abdominal drainage remove, the hospital stay, and alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, albumin 3 days after postoperative were compared between the groups.Results:The times of left Glisson pedicle dissection in the new-fasion and traditional group were (6.1±1.6) min and (13.8±3.0) min, and the time of liver transection was (24.9±3.5) min and (33.4±3.3) min, respectively ( t=-8.34, 6.08, P<0.001 for both). After division of left Glisson pedicle, the MHV was well exposed in 14 cases of new-fashion group and none of traditional group ( P<0.001). All the patients successfully completed the operation without conversion to laparotomy. Intraoperative blood loss, incidence of postoperative bile leakage, time of peritoneal drainage tube removal, postoperative hospital stay, AST, ALT, total bilirubin and albumin 3 days after surgery between the two groups were no significant differences (all P>0.05). Conclusion:LALH using the rapid division of left Glisson pedicle and Arantius tube plane in " one-clamp" fashion could be safe and feasible, the time of left Glisson pedicle and liver transection was short.

Objective:To retrospectively analyze the changes in the proportion of refined lymphocyte subsets in peripheral blood of patients with Graves disease (GD), and their correlation with the clinical characteristics and efficacy of GD, and to explore the immunological pathogenesis of Graves disease for seeking new therapeutic targets.Methods:A total of 97 newly diagnosed GD patients (GD group), 27 patients after treatment (treatment group), and 31 healthy individuals (control group) who visited the Fifth Medical Center of the PLA General Hospital from 2018 to 2021 were included in this study. The data of refined lymphocyte subsets, thyroid function, blood routine and clinical treatment of the three groups were compared and analyzed. The t-test and rank sum test were used to compare the proportions of lymphocyte subsets among different groups, and Pearson correlation analysis was used to analyze the correlation between the proportions of lymphocyte subsets and thyroid function indicators.Results:The proportion of B cells in GD group was higher than that in the control group [16.2%(11.8%, 21.8%) vs 10.2%(8.1%,13.6%)], while the proportion of natural killer (NK) cells was lower [9.4%(4.9%, 13.6%) vs 14.6%(12.1%,18.8%)], and the differences were statistically significant ( P<0.05). Abnormal T cell differentiation: the proportions of functional cells, including activated T cells, memory T cells, clustering antigen(CD)4+memory T cells, Th1 cells, and Tc1 cells, were lower than that in the control group [3.2%(2.1%, 5.7%) vs 5.8%(3.0%, 9.3%), P<0.05; 36.7% (29.9%, 48.1%) vs 48.0%(39.2%,57.7%), P<0.05; 23.1%(17.4%, 30.1%) vs 28.9%(23.3%,34.6%), P<0.05; 16.4% (11.8%, 23.6%) vs 24.3%(16.9%,28.5%), P<0.05; 28.5% (14.7%, 39.2%) vs 46.3%(21.6%,69.2%), P<0.05]. The proportion of activated T cells in the treatment group was higher than that in the GD group [6.5% (4.6%, 13.6%) vs 3.2% (2.1%, 5.7%), P<0.05]. The total triiodothyronine results showed positive correlations with B cells ( r=0.356, P<0.01) and negative correlations with NK cells ( r=?0.416, P<0.01), while the total thyroxine values showed negative correlations with NK cells and activated T cells ( r=?0.318,?0.335; P<0.01). Thyroid stimulating hormone and CD8+initial T cells were positively correlated ( r=0.382, P<0.01). The proportion of B cells, cytotoxic T cells and suppressor T cells in CD8+cells of patients with complications [such as Graves orbitopathy (GO), thyroid toxic cardiomyopathy, etc.] was significantly different from that of the simple GD patients [18.3% (14.1%, 27.1%) vs 14.6% (10.8%, 21.4%), Z=2.54, P<0.05; 73.4%(65.6%,83.6%)vs 65.0%(50.3%,79.3%), Z=2.93, P<0.05; 26.6%(16.4%, 37.5%)vs 35.0%(20.7%,49.7%), Z=?2.74, P<0.05]. The proportion of suppressor T cells in GO patients was lower than that in non-GO patients [6.1% (3.4%, 8.1%) vs 8.5% (4.9%, 13.6%), Z=?3.20 P<0.05]. Conclusion:There are significant alterations in the circulating immune cells of GD patients, suggesting that immunological abnormalities play a crucial role in the onset and progression of the disease.

High-performance phototheranostics with combined photothermal therapy and photoacoustic imaging have been considered promising approaches for efficient cancer diagnosis and treatment. However, developing phototheranostic materials with efficient photothermal conversion efficiency (PCE), especially over the second near-infrared window (NIR-II, 1000-1700 nm), remains challenging. Herein, we report an ultraefficient NIR-II-activated nanomedicine with phototheranostic and vaccination capability for highly efficient in vivo tumor elimination and metastasis inhibition. The NIR-II nanomedicine of a semiconducting biradical oligomer with a motor-flexible design was demonstrated with a record-breaking PCE of 87% upon NIR-II excitation. This nanomedicine inherently features extraordinary photothermal stability, good biocompatibility, and excellent photoacoustic performance, contributing to high-contrast photoacoustic imaging in living mice and high-performance photothermal elimination of tumors. Moreover, a whole-cell vaccine based on a NIR-II nanomedicine with NIR-II-activated performance was further designed to remotely activate the antitumor immunologic memory and effectively inhibit tumor occurrence and metastasis in vivo, with good biosafety. Thus, this work paves a new avenue for designing NIR-II active semiconducting biradical materials as a promising theranostics platform and further promotes the development of NIR-II nanomedicine for personalized cancer treatment.

Objective To investigate the effect of circ_0114427 on apoptosis and inflammation of alveolar epithelial cells induced by lipopolysaccharide (LPS) and its mechanism. Methods Human alveolar epithelial cells were cultured in vitro and transfected with si-circ_0114427, microRNA (miR)-330-5p mimics or co-transfected with si-circ_0114427 and anti-miR-330-5p, and the cellswere then treated with 10 mg/L LPS for 24 hours. The expression levels of circ_0114427 and miR-330-5p in the cells were detected using real-time fluorescent quantitative polymerase chain reaction (qRT-PCR). The protein levels of Cleaved-caspase3 and Cleaved-caspase9 were evaluated using western blot. Enzyme-linked immunosorbent assay (ELISA) was used to assess the expression of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α). Cell apoptosis was analyzed using flow cytometry. The interaction between circ_0114427 and miR-330-5p was validated using a dual luciferase reporter assay. Results After LPS treatment of alveolar epithelial cells, the expression of circ_0114427 was upregulated, while miR-330-5p expression was downregulated in in the cells (P < 0.05). Knockdown of circ_0114427 or upregulation of miR-330-5p could inhibit LPS-induced apoptosis, Cleaved-caspase3, Cleaved-caspase9, IL-6, and TNF-α levels in alveolar epithelial cells (P < 0.05). Circ_0114427 directly interacted with and negatively regulated miR-330-5p. Downregulation of miR-330-5p reversed the inhibitory effect of circ_0114427 knockdown on LPS-induced cell apoptosis and inflammation. Conclusion Knockdown of circ_0114427 can inhibit LPS-induced apoptosis and inflammation in alveolar epithelial cells, possibly through upregulation of miR-330-5p.

Polymyxin B, which is a last-line antibiotic for extensively drug-resistant Gram-negative bacterial infections, became available in China in Dec. 2017. As dose adjustments are based solely on clinical experience of risk toxicity, treatment failure, and emergence of resistance, there is an urgent clinical need to perform therapeutic drug monitoring (TDM) to optimize the use of polymyxin B. It is thus necessary to standardize operating procedures to ensure the accuracy of TDM and provide evidence for their rational use. We report a consensus on TDM guidelines for polymyxin B, as endorsed by the Infection and Chemotherapy Committee of the Shanghai Medical Association and the Therapeutic Drug Monitoring Committee of the Chinese Pharmacological Society. The consensus panel was composed of clinicians, pharmacists, and microbiologists from different provinces in China and Australia who made recommendations regarding target concentrations, sample collection, reporting, and explanation of TDM results. The guidelines provide the first-ever consensus on conducting TDM of polymyxin B, and are intended to guide optimal clinical use.

Objective: To study the association between eating at night and skipping breakfast with college students anxiety symptoms, and to provide reference basis for preventing and alleviating college students anxiety symptoms. Methods: A cross sectional survey was conducted among 9 960 freshman from three universities in Kunming and Dali, Yunnan Province. The dietary frequency questionnaire was used to evaluate the dietary behavior of college students. The Depression Anxiety Stress Scale-21 (DASS-21) was used to evaluate the anxiety symptoms of college students. The association of late night snack and breakfast skipping with the association of anxiety symptoms in college students used generalized linear model and Logistic regression model. Results: The proportion of college students who reported eating at night and breakfast skipping in the last month was 72.5%(7 217/9 960) and 61.6%(6 131/9 960) respectively. The detection rate of anxiety symptoms in college students was 28.9%(2 875/9 960). There was a statistical significance between eating at night with anxiety symptoms( OR =1.40-2.54), and breakfast skipping with anxiety symptoms( OR =1.23-1.60)( P <0.05). The interaction between eating late at night and breakfast skipping was positively correlated with college students anxiety symptoms (multiplicative interaction, β=0.06, 95%CI=0.02- 0.10 , P<0.01; additive interaction, OR=2.00, 95%CI=1.59-2.51, P <0.01). Conclusion The study suggests that the college students who eat at night and frequently skipped breakfast are more likely to have anxiety symptoms. It suggested to promote the formation of healthy eating habits of college students, so as to reduce the occurrence of anxiety sympotoms.
