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.

ObjectiveTo preliminarily confirm the effective anti-lung cancer sites of Momordicae Semen and Epimedii Folium and study their mechanism of action. MethodOn the basis of preliminary research， the extraction method of Momordicae Semen and Epimedii Folium was optimized and the effective parts were screened under the guidance of pharmacological effects. Different ethanol elution and water elution sites of Momordicae Semen and Epimedii Folium were obtained through adsorption and elution with D101 macroporous resin. The methylthiazolyldiphenyl-tetrazolium bromide （MTT） colorimetric assay was used to detect the effects of total drug extracts and different elution sites on the proliferation of various tumor cell lines， and to screen for the optimal elution site and tumor sensitive strains. Flow cytometry was used to detect the effect of the elution sites of Momordicae Semen and Epimedii Folium on intracellular reactive oxygen species （ROS） and apoptosis in A549 cells. Western blot was used to compare the expressions of tumor protein 53 （p53）， Bcl-2-associated X protein （Bax）， cysteinyl aspartate specific proteinase-3 and 9 （Caspase-3 and Caspase-9） proteins in A549 cells. ResultThe inhibitory effect of Momordicae Semen on the proliferation of A549 cells was better than the kernel of Momordicae Semen， with 50% inhibitory concentration （IC₅₀） being （86.83±2.88） mg·L^-1 and （95.10±18.13） mg·L^-1， respectively. The effect of total extracts of Epimedii Folium on A549 anti proliferation IC₅₀ value was （4.71±0.81） mg·L^-1. The IC₅₀ values of the 40%， 60%， and 80% ethanol and anhydrous ethanol eluted macroporous resins of the total extracts of Momordicae Semen and Epimedii Folium inhibiting A549 proliferation were （45.32±4.38）、 （14.95±0.73）、 （17.07±1.76）、 （14.46±2.35）、 （51.7±2.26）、 （12.37±0.67）、 （20.29±0.93）、 and （3.43±0.91） mg·L^-1， respectively. Compared with the normal group， the 1∶1 combination of Momordicae Semen and Epimedii Folium inhibited A549 cell proliferation in a time-dependent and concentration-dependent manner. Compared with the normal group， 50 mg·L^-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased intracellular ROS expression （P<0.01）. Compared with the normal group， 12.5， 25， 50 mg·L^-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of A549 cell apoptosis （P<0.01）. Compared with the normal group， 25， 50 mg·L^-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of p53 in A549 cells （P<0.01）. Compared with the normal group， 12.5， 25， 50 mg·L^-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of Bax （P<0.01）. Compared with the normal group， 50 mg·L^-1 of the combination of Momordicae Semen and Epimedii Folium significantly reduced the expressions of Caspase-3 and Caspase-9 （P<0.01）. ConclusionThe anti-tumor effect of Momordicae Semen is better than that of the kernel of Momordicae Semen. The anti-tumor substances of Momordicae Semen and Epimedii Folium mainly concentrate in the 60% ethanol to anhydrous ethanol elution site. A549 cells are sensitive to the 1∶1 combination of Momordicae Semen and Epimedii Folium， which can effectively inhibit the cell proliferation. The mechanism may be related to increasing the generation of ROS in A549 cells， promoting their apoptosis， increasing the expressions of apoptotic proteins such as p53 and Bax， and reducing the expressions of Caspase-3 and Caspase-9.

Objective To analyze the epidemiological characteristics and epidemic situation of children with Kashin-Beck disease (KBD) in China,and provide the basis for formulating prevention and control measures. Methods Fixed-point monitoring,moving-point monitoring,and full coverage of monitoring were promoted successively from 1990 to 2023. Some children (7-12 years old) underwent clinical and right-hand X-ray examinations every year. According to the KBD diagnosis criteria,clinical and X-ray assessments were used to confirm the diagnosis. Results In 1990,the national KBD detectable rate was 21.01％. X-ray detection decreased to below 10％ in 2003 and below 5％ in 2007. Between 2010 and 2018,the prevalence of KBD in children was less than 0.4％,which fluctuated at a low level,and has decreased to 0％ since 2019. Spatial epidemiological analysis indicated a spatial clustering of adult patients prevalence rate in the KBD areas. Conclusion The evaluation results of the elimination of KBD in China over the last 5 years showed that all villages in the monitored areas have reached the elimination standard. While the adult KBD patients still need for policy consideration and care.

Objective To investigate the effect and mechanism of Twist-related protein 1(TWIST1)on pulmonary vascular remodeling induced by monocrotaline(MCT)in pulmonary arterial hypertension(PAH)rats.Methods A total of 50 healthy male Sprague Dawley(SD)rats were randomly divided into five groups including control group,MCT-treated group,MCT and dimethyl sulfoxide(DMSO)-treated group,MCT and harmine-treated group MCT and hydroxychloroquine(HCQ)-treated group.The right ventricle systolic pressure(RVSP)was measured,right ventricular hypertrophy index(RVHI)and percentage of medial wall thickness(MT％)to assess the development of PAH.The protein levels of TW1ST1,autophagy markers LC3B and RND3 were determined using western blot.Results Compared with control group,expressions of TWIST1 and LC3B were increased by 2.32±0.22 folds and 0.87±0.19 folds in MCT-induced PAH group,with significant differences(t=15.812,11.227,all P＜0.00 1),while the protein level of RND3 in MCT-induced PAH rats was decreased by 0.32±0.07 folds compared with control group,with significant difference(t=-13.003,P＜0.001).Administration of TWIST1 inhibitor Harmine or autophagy inhibitor hydroxychloroquine significantly suppressed MCT-induced increase in LC3B and down-regulation of RND3 expression,and reduced RVSP,RVHI and MT％expressions in MCT-induced PAH rats,with significant differences(t=-24.277～16.636,all P＜0.001).Conclusion TWIST1 promotes pulmonary vascular remodeling by inducing autophagy activation,thus promoting the occurrence and development of PAH.

Purpose To analyze the relationship between different molecular types and imaging manifestations of simultaneous bilateral breast cancer.Materials and Methods Eighty-one patients with simultaneous bilateral breast cancer confirmed by surgery and pathology in the Affiliated Hospital of Qingdao University from January 2016 to May 2022 were retrospectively analyzed,80 patients received mammography and 38 patients received MRI.Imaging features referred to the 5th edition of the breast imaging reporting and data system standards.Molecular typing was evaluated and classified according to the 2013 revised St.Gallen international expert consensus recommended the determination.The clinicopathological and imaging features of the index and contralateral breast cancer were compared,and the imaging features of different molecular types of the index and contralateral breast cancer were also compared.Results There were statistically significant differences in histological types and molecular typing between the index and contralateral cancers(x2=39.72,12.23,P＜0.05).Mammograph showed that the index cancer was mostly a mass(51.9％,40/77),while the contralateral cancer was mostly calcification(38.4％,28/73);the index cancer was mostly polymorphic calcification(68.8％,22/32),while the contralateral cancer was mostly amorphous calcification(45.2％,19/42)(x2=33.15,10.47,P＜0.05).There was a statistically significant difference in the MRI enhancement between the index cancer and the contralateral cancer(x2=6.79,P＜0.05).For contralateral cancer,mammograms showed statistically significant differences in the four molecular subtypes on tumor density,as well as MRI enhancement patterns,early enhancement degree,and time-signal intensity curve(x2=26.72,7.49,8.95,13.44,12.85,P＜0.05).There was a significant difference in the distribution of calcification among the four molecular subtypes on the X-ray of the first cancer(x2=20.15,P＜0.05).Conclusion The molecular typing and some imaging characteristics of simultaneous bilateral breast cancer are different,and some imaging characteristics can provide reference for predicting the molecular typing of simultaneous bilateral breast cancer.

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.

Objective To explore the relationship between the status of infarct related artery(IRA)occlusion and thrombus types in patients with non-ST-segment elevation myocardial infarction(NSTEMI)using optical coherence tomography(OCT).Methods A total of 170 NSTEMI patients who underwent emergency percutaneous coronary intervention at Henan Provincial People1s Hospital from October 2021 to August 2023 and underwent OCT examination were included in the study.Among them,83 cases were in the total occlusion group and 87 cases were in the non-total occlusion group.The baseline characteristics,coronary angiography findings,and OCT results of the patients were compared and analyzed.Results Compared with the non-total occlusion group,the patients in the total occlusion group were more younger(P=0.013),the proportion of male was higher(P=0.026),and the proportion of patients with hypertension(P=0.010)and diabetes(P=0.033)was lower.In the total occlusion group,left circumflex artery(LCX)served as the main IRA,whereas in the non-total occlusion group,left anterior descending(LAD)was the predominant IRA(P=0.012);In addition,there was a significantly higher occurrence of rentrop grade Ⅱ～Ⅲ in the total occlusion group compared to the non-total occlusion group(P=0.022).The OCT results showed that in most cases,the total occlusion group was caused by plaque rupture events(P=0.014),mainly red/mixed thrombus(P＜0.001);The non-total occlusion group was more commonly associated with plaque erosion events(P=0.014),with white thrombus being the main cause(P＜0.001).Conclusions Total occlusion of infarct-related artery in NSTEMI patients often occurs in the LCX,and the patient is more younger,the thrombus type is mainly red/mixed thrombus,while non-total occlusion lesions are mainly white thrombus.

Electrochemiluminescence(ECL)refers to the process of luminescence triggered by high-energy electron transfer between intermediate products during the oxidation-reduction reaction on the electrode surface.In the co-reactants involved ECL process,the presence of co-reaction accelerators can effectively catalyze the decomposition of co-reactants,leading to the generation of abundant free radical intermediates,thereby significantly enhancing the ECL signals.This plays a critical role in constructing simple,sensitive,and efficient ECL sensing platforms.This review focused on the novel co-reaction accelerators developed in recent years.Based on different types of co-reaction accelerator materials,including single atom catalysts,metal-based nanomaterials,polymers and other materials,the ECL reaction process and signal enhancement mechanisms,as well as their relevant applications in constructing ECL sensing platforms,were elucidated.Furthermore,the current research challenges and development prospect of co-reaction accelerators were also discussed.

Objective To investigate the effect of Hedyotis diffusa extract(HDE)on the proliferation of liver cancer cells and its relationship with sugar metabolism reprogramming and oxidative phosphorylation and analyze its possible mechanisms.Methods CCK-8 and EDU experiments were used to determine the effect of different concentrations(20,40,80 mg/mL)of HDE on the growth of liver cancer cell line SNU-368.Lactate dehydrogenase activity,glucose uptake,lactate production,extracellular pH,mitochondrial respiratory chain complex activity,and cellular oxygen consumption were measured to analyze the effect of HDE on aerobic glycolysis and oxidative phosphorylation in liver cancer cells.qRT-PCR experiments were used to detect the mRNA expressions of GLUT1,GLUT4,HK2,GPI,PFKL,ALDOA and HIF-1α in SNU-368 cells of different groups.Western blotting experiments were used to detect the protein expression of HIF-1α.A stable cell line overexpressing HIF-1αwas constructed by lentivirus transfection of liver cancer cells SNU-368 and then intervened with HDE;the expression of HIF-1α mRNA and protein was detected with qRT-PCR and Western blotting.Results CCK-8 results showed that the HDE exhibited a concentration-dependent inhibitory effect on the proliferation of liver cancer cells(all P＜0.05).Results from glucose metabolism-related tests indicated that the HDE could inhibit glucose uptake and lactate production,decrease lactate dehydrogenase activity,increase extracellular pH value,enhance cellular oxygen consumption,and elevate activities of mitochondrial respiratory chain complexes Ⅰ,Ⅱ,Ⅲ and Ⅳ(all P＜0.05).qRT-PCR results revealed that the HDE suppressed the mRNA expressions of GLUT1,HK2,GPI,and ALDOA(all P＜0.05).qRT-PCR and Western blotting experiments showed that compared to the control group,the expression of HIF-1α mRNA and protein in the HDE group was significantly reduced.However,when HIF-1α was overexpressed and HDE was added in the HIF-1α-LV group,the expression of HIF-1α mRNA and protein increased again compared to the HDE group.Conclusion HDE inhibits glycolysis and promotes oxidative phosphorylation to inhibit the proliferation of liver cancer cells,and its mechanism of action may be related to the inhibition of HIF-1α expression.
