Triggering receptor expressed on myeloid cells 2 （TREM2） is expressed in resident non-parenchymal cells （NPCs） and is involved in various pathological processes including liver inflammation and immunoregulation. In recent years， TREM2 has attracted attention in the field of acute and chronic liver diseases， and more and more studies have shown that TREM2 is a potential target for the treatment of acute and chronic liver diseases； however， there is a lack of systematic summary for the mechanism of action of TREM2 in acute and chronic liver diseases. Therefore， this article reviews the latest research advances in the regulatory role of TREM2 in acute and chronic liver diseases， in order to provide new ideas for the clinical prevention and treatment of acute and chronic liver diseases.

Objective To understand the surveillance situation of poliovirus in Guangzhou from 2011 to 2024, and to further strengthen polio surveillance and ensure the continued maintenance of a polio-free status. Methods An analysis was conducted on the discovery and investigation results of six cases of vaccine-derived poliovirus (VDPV) detected in Guangzhou. Results A total of 6 VDPV incidents were reported in Guangzhou from 2011 to June 2024, among which 5 incidents were from sewage sample testing in the Liede Sewage Treatment Plant in Guangzhou, all of which were confirmed as VDPV, with 1 for type I, 1 for type II, and 3 for type III. In addition, one confirmed HFMD case was identified as a type VDPV II carrier. No presence of any wild poliovirus (WPV), VDPV cases, or circulating VDPV (cVDPV) was reported. Conclusion Guangzhou City has maintained a high level of vigilance and effectiveness in the monitoring and prevention of polio. Continuously strengthening the construction of the polio monitoring network, optimizing vaccination strategies, and comprehensively improving public health awareness are still the focus of the prevention and control work in the future.

Objective:To investigate the impact of early removal of nasogastric tubes on functional recovery after total gastrectomy for gastric cancer patients, to provide scientific evidence for enhanced recovery after surgery strategies in gastric cancer.Methods:A retrospective cohort study was conducted on 102 gastric cancer patients who underwent total gastrectomy at Beijing Friendship Hospital affiliated with the Capital Medical University from March 2018 to July 2022. Patients were divided into two groups based on whether the gastric tube was removed within 24 hours post-operation: the early removal group (within 24 hours, 55 patients) and the non-early removal group (beyond 24 hours, 47 patients). The recovery outcomes, including time to first flatus, time to fluid intake, length of hospital stay, and the incidence of postoperative complications, were compared between the two groups. Non-normally distributed data were expressed as M( Q1, Q3) and compared using the Wilcoxon rank-sum test. Categorical data were expressed as frequencies or percentages and compared using the chi-square test or Fisher′s exact test. To minimize the impact of potential confounders, multivariable linear regression and logistic regression analyses adjusted for propensity scores were further employed to compare quantitative and qualitative data between the groups. Statistical analyses were performed using R software. Results:The exhaust time, water intake time, and hospital stay in the early removal group were 3.0(2.0, 3.5) days, 4.0(3.0, 5.0) days, and 7.0(7.0, 8.0) days, respectively, while those in the non-early removal group were 4.0(3.0, 5.0) days, 6.0(5.0, 7.0) days, and 8.0(7.5, 11.0) days, respectively. Statistically significant differences were observed between the two groups ( P<0.05). However, there was no significant difference in the incidence of postoperative complications between the two groups (5.45% vs 17.02%, P=0.060). Propensity score-adjusted regression analysis suggested that early tube removal might reduce the risk of postoperative complications ( P=0.042). Conclusion:Early removal of nasogastric tubes can significantly accelerate functional recovery after total gastrectomy for gastric cancer patients and may reduce the risk of postoperative complications, providing important clinical guidance for enhanced recovery after surgery management in gastric cancer.

Objective:To investigate the mechanism of polygonatum and astragalus compound(PA)in inhibiting the progression of lung adenocarcinoma. Methods:CCK-8 assay was used to assess the inhibitory rate of proliferation in A549 and H1299 cells treated with PA at different concentrations and to calculate the half maximal inhibitory concentration(IC50).C57BL/6 mice(KRASG12D/+;TP53flox/flox)were treated with adenovirus carrying Cre enzyme via nasal inhalation to establish a mouse model of primary lung adenocarcinoma.The model mice were fed with PA-containing diet to directly observe the effect of PA on the lung adenocarcinoma tissue.Immunohistochemical staining was used to examine the pathological status of the lung tissue.Bioinformatics analysis indicated that PA affects the progression of lung adenocarcinoma through the apelin-peroxisome proliferator-activated receptor gamma coactivator 1-alpha(PGC1α)-mitochondrial brown fat uncoupling protein 1(UCP1).Real-time quantitative PCR and Western blotting analysis were used to study the effect of PA on the mRNA and protein expression levels of apelin-PGC1α-UCP1 signaling pathway related genes.An ATP detection kit and flow cytometry were used to evaluate the effect of PA on the ATP and mitochondrial ROS production,respectively,in A549 and H1299 cells.siUCP1 was used to silent the expression of UCP1 while Z160 was used to induce UCP1 overexpression in A549 and H1299 cells,and the changes in ATP and mitochondrial ROS production were examined to further investigate whether PA acts on apelin-PGC1α-UCP1 signaling pathway to affect the progression of lung adenocarcinoma. Results:PA could obviously inhibit the proliferation of A549 and H1299 cells with the IC50 values of 10.66 mg/mL for A549 cells and 9.66 mg/mL for H1299 cells.In the mouse primary lung adenocarcinoma model,PA could effectively inhibit the growth of tumor,downregulate apelin-PGC1α-UCP1 signaling pathway and inhibit the expression of lung adenocarcinoma-promoting gene UCP1.In A549 and H1299 cells,PA could significantly inhibit the expression of apelin,PGC1α and UCP1(P＜0.05),promote the production of ATP(P＜0.000 1)and ROS,restore mitochondrial oxidative phosphorylation,and inhibit aerobic glycolysis(P＜0.01).UCP1 silencing could increase the production of ATP(P＜0.01)and mitochondrial ROS and decrease the expression of key glycolysis enzymes hexokinase 2(HK2)and pyruvate kinase isozyme type M2(PKM2)(P＜0.05).Increasing the expression of UCP1 could reduce the ATP production(P＜0.01)and mitochondrial ROS generation in cells while increase the expression of HK2 and PKM2(P＜0.05).Treating cells with PA and Z160 simultaneously(PA+Z160)could reverse the inhibitory effect of PA on the ATP production and glycolysis of tumor cells(P＜0.05). Conclusion:PA can downregulate the apelin-PGC1α-UCP1 signaling pathway,inhibit mitochondrial uncoupling,restore mitochondrial oxidative phosphorylation,inhibit aerobic glycolysis,reverse the Warburg effect,and thus inhibit lung adenocarcinoma progression.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
