Objective To explore the effectiveness of the cumulative sum (CUSUM) and the exponentially weighted moving average (EWMA) for early warning of influenza epidemic using two datasets of reported influenza cases and influenza-like illness (ILI) cases. Methods Using the reported cases of influenza and ILI in Daxing District, Beijing, from week 23 of 2018 to week 22 of 2024 as data sets, the CUSUM and EWMA models were established, respectively. The positive rate of influenza etiology was used as the ^“gold standard^”, and the Youden index was used as the evaluation index to compare the early warning effect of the two models under different data sets and different parameters. Results In CUSUM, the optimal Youden indices of the reported influenza cases set and the ILI cases set were 0.751 and 0.635, respectively. In EWMA, the optimal Youden indices of the reported influenza cases set and the ILI cases set were 0.544 and 0.464, respectively. The optimal EWMA and CUSUM models could both issue early warning signals in advance of the ^“gold standard^”. Conclusion In the influenza epidemic early warning in Daxing District, Beijing, the CUSUM model established with the reported cases of influenza can achieve good early warning effects, but the model parameters need to be dynamically adjusted according to the local epidemic characteristics.

Objective To explore the impact of tumor-associated myeloid cell infiltration signatures on postoperative overall survival (OS) in patients with gastric cancer. Methods A retrospective analysis was performed on patients who underwent radical gastrectomy at Zhongshan Hospital, Fudan University from January 2005 to December 2019. Patients were randomly divided into a training set (n＝167) and an internal validation set (n＝168) at a 1:1 ratio. Meanwhile, 147 patients with gastric cancer treated at Zhongshan Hospital (Xiamen), Fudan University during the same period were enrolled as the external validation set (n＝147). Immunohistochemistry was used in all patients to evaluate the distribution characteristics of 18 immune markers in three regions of gastric cancer tissues, namely primary tumor (PT), invasive margin (IM), and normal tissue (NT). These markers include 11 myeloid cell markers (CD11b, CD33, CD11c, CD14, CD15, CD16, CD68, CD86, CD163, CD206, and CD66b) and 7 immune checkpoints (CD73, IDO, LAG3, PD-1, SIGLEC9, SIRPA, and TIM3). LASSO regression and Cox proportional hazards model were applied to screen immune markers associated with postoperative OS in gastric cancer patients, and a predictive model for 1-, 3-, and 5-year postoperative OS was established. Data from the internal and external validation set were used for internal and external verification of the predictive model. Receiver operating characteristic (ROC) curves were plotted and the area under the curve (AUC) was calculated to assess the discriminative ability of the model. Results In the training set, LASSO regression and Cox proportional hazards model identified 4 immune marker signatures (CD14_PT, CD15_PT, CD206_PT, and SIGLEC9_PT) to construct the predictive model. ROC curve analysis showed that the AUCs of the model for predicting 1-, 3-, and 5-year postoperative OS were 0.74, 0.75, and 0.84, respectively. When the model was applied to the internal and external validation sets, the AUCs for 1-, 3-, and 5-year postoperative OS were 0.74, 0.72, 0.72 (internal validation set) and 0.72, 0.71, 0.74 (external validation set), respectively. Cox multivariate regression analysis showed that the risk score was an independent risk factor for postoperative OS in patients with gastric cancer. Conclusion The model constructed based on LASSO-Cox regression exhibits good predictive performance and can effectively predict postoperative OS in gastric cancer patients, which may serve as a basis for intensive treatment of high-risk patients after surgery.

Objective: To investigate the occurrence of adverse events following immunization (AEFI) with meningococcus-containing vaccine (MCV) in Jiaxing City, Zhejiang Province from 2020 to 2024, so as to provide the evidence for MCV safety monitoring and evaluation. Methods : AEFI surveillance data following MCV vaccination were collected through the Immunization Program Information Management System of the China Disease Prevention and Control Information System, and MCV vaccination data were collected through the Zhejiang Provincial Immunization Program Smart Service Information System. Descriptive analyses were performed to examine the demographic distribution, temporal distribution, and regional distribution of AEFI cases, as well as the doses of MCV administered, the interval between vaccination and AEFI onset, clinical symptoms of AEFI, and outcomes. Results: From 2020 to 2024, a total of 263 AEFI cases were reported in Jiaxing City, with an average annual reported incidence of 27.73/105 doses, showing an increasing trend (P<0.05). Common adverse reactions predominated, accounting for 230 cases (87.45%), with the reported incidence of 24.25/105 doses. Among AEFI cases, 139 (52.85%) were males and 124 (47.15%) were females. The majority of cases were aged <2 years, accounting for 156 cases (59.32%). The number of reported AEFI cases was relatively high in the second and third quarters, with 75 and 77 cases, accounting for 28.52% and 29.28%, respectively, and reported incidence of 29.48/105 doses and 29.71/105 doses, respectively. Haiyan County and Pinghu City reported relatively higher numbers of cases, with 44 cases each, accounting for 16.73% each, and reported relatively higher AEFI incidence of 58.91/105 doses and 40.46/105 doses, respectively. Following the 1st, 2nd, 3rd, and 4th doses of MCV, 136, 111, 14, and 2 AEFI cases were reported, accounting for 51.71%, 42.21%, 5.32%, and 0.76%, respectively, with reported incidence of 30.63/105 doses, 23.24/105 doses, 55.59/105 doses, and 120.63/105 doses, respectively. A total of 198 AEFI cases (75.29%) were reported within 1 day after MCV vaccination. Among common adverse reaction cases, the predominant clinical symptoms were fever and local redness/swelling, occurring in 151 and 49 cases, accounting for 57.41% and 18.63%, respectively, with reported incidence of 15.92/105 doses and 5.17/105 doses, respectively. Conclusions From 2020 to 2024, the average annual reported incidence of AEFI following vaccination with five types of MCV in Jiaxing City was relatively low, but an increasing trend was observed. Common adverse reactions predominated. AEFI cases were concentrated in children aged <2 years, with relatively higher incidence in summer and autumn, as well as in Haiyan County and Pinghu City. Most cases occurred after the first dose of MCV and within 1 day post-vaccination, with fever and local redness/swelling being the main clinical symptoms.

Objective: To analyze the epidemiological characteristics and spatial-temporal clustering of influenza in Lishui City, Zhejiang Province from 2016 to 2025, so as to provide a reference for formulating regional influenza prevention and control strategies. Methods: Data on influenza cases in Lishui City from 2016 to 2025 were collected from the Infectious Disease Reporting Information System of China Disease Prevention and Control Information System. Descriptive epidemiological methods were used to analyze the temporal, population and regional distribution characteristics of influenza. The concentration ratio (M) method was used to evaluate seasonality. Spatial autocorrelation and spatial-temporal scan analysis were used to explore the spatial-temporal clustering. Results: A total of 192 016 influenza cases were reported in Lishui City from 2016 to 2025, with an average annual reported incidence of 774.32/105, showing an overall upward trend (P<0.05). The incidence peaked from November to March of the following year, indicating strong seasonality (M=0.661). There were 99 513 males and 92 503 females, with a male-to-female ratio of 1.08∶1. The majority of cases were aged 5-<15 years and were students, with 86 766 and 82 286 cases, accounting for 45.19% and 42.85%, respectively. The average annual reported incidence of influenza was relatively high in Songyang County, Jingning She Autonomous County and Yunhe County, with 1 255.22/105, 1 176.23/105 and 1 129.76/105, respectively. Spatial autocorrelation analysis showed a positive spatial correlation of influenza incidence in Lishui City from 2016 to 2025 (all P<0.05). From 2016 to 2018, the high-high clusters were mainly distributed in the northeastern region, while from 2019 to 2025, mainly distributed in the central and southern regions. Spatial-temporal scan analysis showed that the Class Ⅰ cluster was centered on Yuanhe Subdistrict in Yunhe County, covering Liandu District, Yunhe County, and Songyang County in the central region, as well as Jingning She Autonomous County and Longquan City in the southern region, involving 54 towns (subdistricts), with the clustering period from March 2023 to December 2025. Conclusions From 2016 to 2025, the reported incidence of influenza in Lishui City showed an upward trend, with a peak in winter and spring and strong seasonality. Children and adolescents aged 5-<15 years and students were identified as high-incidence populations. The incidence showed spatial-temporal clustering, with the central and southern regions being high-incidence areas.

BACKGROUND: Chronic kidney disease (CKD) is associated with common pathophysiological processes, such as inflammation and fibrosis, in both the heart and the kidney. However, the underlying molecular mechanisms that drive these processes are not yet fully understood. Therefore, this study focused on the molecular mechanism of heart and kidney injury in CKD. METHODS: We generated an microRNA (miR)-26a knockout (KO) mouse model to investigate the role of miR-26a in angiotensin (Ang)-II-induced cardiac and renal injury. We performed Ang-II modeling in wild type (WT) mice and miR-26a KO mice, with six mice in each group. In addition, Ang-II-treated AC16 cells and HK2 cells were used as in vitro models of cardiac and renal injury in the context of CKD. Histological staining, immunohistochemistry, quantitative real-time polymerase chain reaction (PCR), and Western blotting were applied to study the regulation of miR-26a on Ang-II-induced cardiac and renal injury. Immunofluorescence reporter assays were used to detect downstream genes of miR-26a, and immunoprecipitation was employed to identify the interacting protein of LIM and senescent cell antigen-like domain 1 (LIMS1). We also used an adeno-associated virus (AAV) to supplement LIMS1 and explored the specific regulatory mechanism of miR-26a on Ang-II-induced cardiac and renal injury. Dunnett's multiple comparison and t -test were used to analyze the data. RESULTS: Compared with the control mice, miR-26a expression was significantly downregulated in both the kidney and the heart after Ang-II infusion. Our study identified LIMS1 as a novel target gene of miR-26a in both heart and kidney tissues. Downregulation of miR-26a activated the LIMS1/integrin-linked kinase (ILK) signaling pathway in the heart and kidney, which represents a common molecular mechanism underlying inflammation and fibrosis in heart and kidney tissues during CKD. Furthermore, knockout of miR-26a worsened inflammation and fibrosis in the heart and kidney by inhibiting the LIMS1/ILK signaling pathway; on the contrary, supplementation with exogenous miR-26a reversed all these changes. CONCLUSIONS Our findings suggest that miR-26a could be a promising therapeutic target for the treatment of cardiorenal injury in CKD. This is attributed to its ability to regulate the LIMS1/ILK signaling pathway, which represents a common molecular mechanism in both heart and kidney tissues.

Metabolic dysfunction-associated steatotic liver disease (MASLD) comprises a spectrum of liver injuries, including steatosis to steatohepatitis (MASH), liver fibrosis, cirrhosis, and relevant complications. The liver mainly comprises hepatocytes, liver sinusoidal endothelial cells (LSECs), Kupffer cells (KCs), immune cells (T cells, B cells), and hepatic stellate cells (HSCs). Crosstalk among these different liver cells, endogenous aberrant glycolipid metabolism, and altered gut dysbiosis are involved in the pathophysiology of MASLD. This review systematically examines advances in understanding the molecular pathogenesis of MASLD, with a focus on emerging therapeutic targets and translational clinical trials. We first delineate the crucial regulatory mechanisms involving diverse liver cells and the gut-liver axis in MASLD development. These cell-specific pathogenic insights offer valuable perspectives for advancing precision medicine approaches in MASLD treatment. Furthermore, we evaluate potential therapeutic targets and summarize clinical trials currently underway. By comprehensively updating the MASLD pathophysiology and identifying promising strategies, this review aims to facilitate the development of novel pharmacotherapies for this increasingly prevalent condition.

Objective To investigate the clinical effect of free electromyography(fEMG)monitoring as-sisted unilateral biportal endoscopy(UBE)in the treatment of lumbar disc herniation.Methods Forty pa-tients with lumbar disc herniation were included.The UBE lumbar nucleus pulposus resection under general anesthesia was performed.The operation whole process was completed under the fEMG monitor.The recorded potential was displayed on the monitor screen and the myoelectrical activity was played through speaker.The treatment effect was evaluated by the Visual Analogue Scale(VAS)score and Oswestry Disability Index(ODI).Results All 40 patients completed the surgery successfully,and the postoperative symptoms were im-proved significantly.The VAS scores before operation and in postoperative 3 months were 7(6,8)points and 0(0,1)points respectively,and the difference between the two time points was statistically significant(P＜0.05).The ODI before operation and in postoperative 3 months were(58.30±11.58)and(13.28±5.20)re-spectively,and the difference between the two time points also was statistically significant(P＜0.05).The VAS score and ODI in postoperative 1 year were 1(0,1)points and(13.13±0.40)respectively,showing sta-tistically significant difference compared with before surgery(P＜0.05),but there was no statistically signifi-cant difference compared with postoperative 3 months(P＞0.05).There were 8 cases developing the abnor-mal EMG changes such as spike,burst or tonic fEMG during surgery,with an incidence rate of 20％.After surgery in 8 cases,7 cases had burning radiculalgia and paresthesia of lower extremity,and 1 case had no obvi-ous neuralgia,with a false positive rate of 12.5％.The patients without abnormal fEMG reaction during sur-gery had no significant postoperative neuralgia,and the false negative rate was zero.Conclusion fEMG moni-toring assisted UBE under general anesthesia is a safe and easy method for the treatment of lumbar disc herni-ation.

ObjectiveTo observe the analgesic efficacy and safety of Qihuang acupuncture theory combined with opioid analgesics in patients with moderate to severe cancer pain due to lung cancer. MethodsPatients with moderate to severe cancer pain from lung cancer were randomly divided into Qihuang acupuncture group and control group， with 33 cases in each group. The control group was treated with long-acting opioid analgesics at maintenance doses and supplementary analgesic medications as needed. In case of breakthrough pain， short-acting opioids were used for rescue. The Qihuang acupuncture group received Qihuang acupuncture treatment in addition to the treatment used in the control group， administered once every other day， with 3 sessions constituting one treatment course. The treatment duration for both groups was 5 days. The primary outcome was the change in pain intensity， measured using the numerical rating scale （NRS） before and after treatment， and the NRS change rate was calculated. Secondary endpoints included the daily NRS change rate， the Eastern Cooperative Oncology Group （ECOG） Performance Status （PS） score， the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire （EORTC QLQ-C30） score， and the 24-hour equivalent hydrocodone sustained-release tablet dose. Laboratory tests， including routine blood， urine， stool， liver function， and kidney function， were performed before and after treatment. Adverse events were recorded throughout the trial. ResultsAll patients completed the trial， and both groups showed a decrease in average NRS scores and PS scores after treatment， with the Qihuang acupuncture group showing lower average NRS scores and PS scores than the control group （P＜0.05 or P＜0.01）. After treatment， the NRS change rate in the Qihuang acupuncture group was （0.42±0.17）， significantly higher than that in the control group （0.14±0.27， P＜0.01）. The daily NRS change rate during treatment was also higher in the Qihuang acupuncture group compared to the control group （P＜0.01）. The Qihuang acupuncture group showed an increase in overall health status and functional scores in the EORTC QLQ-C30， and a decrease in symptom scores for fatigue， nausea and vomiting， pain， dyspnea， insomnia， appetite loss， constipation， and financial difficulties. In contrast， overall health status and constipation scores in the control group increased， while scores of fatigue， nausea and vomiting， pain， and appetite loss decreased （P＜0.05 or P＜0.01）. After treatment， the 24-hour equivalent hydrocodone sustained-release tablet dose did not show significant difference in the Qihuang acupuncture group （P＞0.05）， while the control group showed a significant increase in the 24-hour dose （P＜0.01）. No significant abnormalities were observed in laboratory tests before and after treatment in either group. During the study， the incidence of nausea and vomiting as well as constipation in the Qihuang acupuncture group was both 3.03% （1/33）， while the incidence in the control group was 27.27% （9/33） and 36.36% （12/33）， respectively， with the Qihuang acupuncture group showing significantly lower incidence （P＜0.01）. No serious adverse reactions were observed in either group. ConclusionQihuang acupuncture therapy combined with opioid analgesics is more effective than using opioids alone in relieving pain in patients with moderate to severe cancer pain due to lung cancer. It can improve the patients' physical condition and quality of life， reduce the dose of opioid analgesics， and has good safety.

Baxian Formula （八仙方） is a folk pediatric prescription in Quanzhou， Fujian Province. This paper summarized the clinical experience of Professor LI Candong in treating pediatric diseases with Baxian Formula. By analyzing the distinctive composition and theoretical underpinnings of the Baxian Formula for treating pediatric lung， liver and spleen diseases， it is considered that the formula prioritizes wind medicinals， aimed at restoring the dynamics of qi movement within the zang fu （脏腑） organs. It excels in dispelling and dispersing wind， promoting digestion， calming the mind， invigorating the spleen and draining dampness， clearing heat and soothing the liver， extinguishing wind and arresting convulsion. The prescription can treat pediatric disorders caused by pathological factors such as wind， phlegm， dampness， food， heat and constraint. Moreover， this paper summarized the clinical thinking of Baxian Formula in treating pediatric diseases of the lung system （common cold， cough， eczema）， spleen system （diarrhea， food retention） and liver system （fright from external stimuli， tic disorder）， aiming at providing reference for diagnosing and treating pediatric diseases in clinical practice.
