Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.

A 55-year-old male patient was admitted to the hospital due to "recurrent chest pain for 8 months, with worsening symptoms for 2 weeks". After admission, comprehensive relevant examinations led to the consideration of a giant chronic left ventricular pseudoaneurysm caused by myocardial infarction with non-obstructive coronary arteries. Surgical treatment was performed at our hospital. We discuss the diagnosis and treatment of this patient.

Objective:To establish an indicator system for surveillance of data sources to provide a theoretical basis for respiratory infectious disease surveillance and early warning.Methods:Indicators for data sources in the surveillance of acute respiratory infectious diseases were initially compiled through a literature search. Subsequently, two rounds of expert consultations were conducted with 22 experts using the Delphi method to refine the indicators.Results:The questionnaire recovery rates for the two rounds of expert consultation were 100.00% and 86.36%, respectively. The authority coefficient of the experts was 0.83. The coordination coefficient of the second round of Delphi expert consultation was 0.32, and the coefficient of variation of each indicator was less than 0.25. Finally, the indicators system of data source for the surveillance of acute respiratory infectious diseases includes 4 first-level indicators, 10 second-level indicators, and 26 third-level indicators.Conclusion:The indicator system of data sources for the surveillance of acute respiratory infectious diseases constructed in this study is reasonable and reliable, providing a valuable reference for surveillance, early warning and policy formulation of acute respiratory infectious diseases.

Vaccination is an effective public health measure to prevent and control vaccine-preventable diseases for individual and society. However, China currently confronts significant challenges, including a dearth of skilled professionals in the field of vaccination and disparities in the capacity for immunization services. This review introduced the experiences of four prime international vaccinology education models, including London School of Hygiene & Tropical Medicine, Johns Hopkins University, Leading International Vaccinology Education, and the Bill & Melinda Gates Foundation, in the aspect of personnel development, academic research and communication platforms establishment. It is supposed to give some insights and feasible suggestions on the establishment and advancement of vaccinology as a sub-discipline within high-level public health school in China, with the aim of development of a robust vaccinology education framework in China, which is essential for nurturing the next generation of public health leaders and practitioners for our country.

Objective To study the changes of blood glutathione peroxidase (GSH-px),superoxide dis-mutase (SOD),malondialdehyde (MDA) and pathological tissues in the rat contrast-induced nephropathy (CIN) model,and to determine the role of oxidation mechanism in CIN.Methods A total of 40 adult male SD rats were selected and divided into three big groups and five small groups.After constructing the model,six rats with good status were taken from each group for conducting the experiment.The serum GSH-px,SOD and MDA levels were measured,the renal tissue biopsy was performed and the morphological changes of kid-ney cells were compared.Results There was no statistically significant difference in the baseline data among the blank control group,the control group and the experimental group (P>0.05).There was no statistically significant difference in serum GSH-px,SOD and MDA levels before model construction,at 24,48 h after model construction between the blank control group and the control group (P>0.05).There were statistical-ly significant differences in serum GSH-px,SOD and MDA levels of the experimental group between before model construction and after model construction (P<0.05).There was no statistically significant difference in serum GSH-px,SOD and MDA level in the experimental group between at 24 h after modelling and 48 h af-ter modeling (P>0.05).There was no statistically significant difference in serum GSH-px,SOD and MDA levels at 24 h after modeling among the three groups (P>0.05).There were statistically significant differ-ences in serum GSH-px,SOD and MDA levels at 48 h after modeling among the three groups and their pairs (P<0.05).The pathological sections of the blank control group and control group showed no obvious abnor-mal changes in glomeruli,renal tubule and renal interstitium.Renal interstitial fibrosis and inflammatory cell infiltration were seen after 24 h in the experimental group,but there was no obvious change in the renal tu-bules.After 48 h,moderate focal-like atrophy of renal tubules,epithelial cell granule degeneration and vacuolar changes were obviously seen.Conclusion The oxidative stress mechanism plays a role in CIN.The contrast a-gent acute renal injury mainly acts on the renal tubules and renal interstitium,and there is no obvious damage to the glomeruli.

AIM: To investigate the effects of autotransfusion on immune function and inflammation in patients undergoing cesarean section. METHODS: Ninty patients with high risk hemorrhage (central placenta previa, cicatritic uterus, etc.) who underwent cesarean section were divided into three groups according to the amount of autoblood transfusion, with 30 cases in each group. The control group did not receive autologous blood transfusion, the group with a transfusion volume of 0-400 mL received autologous blood transfusion 0-400 mL, and the group with a transfusion volume of 400-800 mL received autologous blood transfusion 400 -800 mL. Serum levels of HB, RBC, HCT, WBC, CD3

Human still has limited understanding of respiratory infectious diseases, especially emerging acute respiratory infectious diseases. Once the pandemic of this kind of infectious disease occur, it would be a serious challenge to health, political security, the economic development, and social stability. People hope to detect the changes in infectious diseases in early phase through surveillance and give early warning in time. In the field of public health, more attention has been paid to syndrome surveillance as an effective supplement to traditional surveillance. This paper summarizes the current surveillance system of infectious diseases abroad, introduces the syndrome surveillance system of acute respiratory infectious disease and its application in China, and discusses the development of syndrome surveillance and early warning technology for acute respiratory infectious diseases in the future.
