Helicobacter pylori(H.pylori)infection is the most significant controllable risk factor for gastric cancer,and its eradication is a critical component of gastric cancer prevention in China.A family-based screening and treatment strategy for H.pylori aligns well with China's public health needs.It demonstrates higher eradication success rate,lower recurrence rate,and superior cost-effectiveness,making it suitable for both high-and low-prevalence regions.Implementation of this family-based strategy can lead to greater precision,higher efficiency,and overall coverage in gastric cancer prevention in China,offering a scalable"China model"for global gastric cancer control.

As China is a country with high incidence of gastric cancer,it is of great significance to actively carry out mass screening at the population level for early diagnosis and treatment of gastric cancer.Current practical experience shows that the selection of screening methods and patterns is closely related to the compliance of the target population,screening coverage and lesion detection rate.Currently,mature gastric cancer screening methods include serologic examination,gastroscopy,liquid biopsy,etc.,while screening patterns include"one-step strategy"based on gastroscopy and"sequential strategy"combining serologic examination and gastroscopy.The purpose of this paper is to review the current mainstream status of gastric cancer screening methods and patterns,and to draw on the potential advantages of other cancer screening methods,with a view to providing reference for the exploration of feasible pathways for gastric cancer screening,and further contributing to the standardization of gastric cancer screening in China.

According to the current meditech conditions in China,we combined the domestic and overseas first aid modes and the problems in severe trauma together and inducted the methods of model study into the procedure of traumatic first aid.The purpose of the study is to establish the procedure of inner-hospital first aid in severe trauma.Through the investigation and practice in Daping Hospital,Third Military Medical University,on the basis principles of organizing first aid with high efficiency,shortening preoperative time and enhancing achievement ratio of remedy,we established the procedure of inner hospital first aid with the typical character of time-control mode.This method can effectively enhance achievement ratio of remedy,decrease the ratio of disability.Moreover,it may promotes the process of entirety,systematization and specialization of inner-hospital first aid in severe trauma.

Objective To explore the changes and clinical significances of serum vascular endothelial growth factor (VEGF) and endostatin concentrations for early detection of lung cancer in elderly long-term smokers. Methods Serum VEGF and endostatin concentrations were determined in 52 elderly long-term smokers and 20 elderly non-smokers by enzyme linked immunoabsent assay (ELISA) or competitive enzyme immunoassay. The 52 elderly long-term smokers were divided into lung cancer group (n = 32) and non-lung cancer group (n = 20). Results The concentration of serum VEGF was markedly higher in lung cancer group [(15. 7±8. 0) ng/L] than in non-lung cancer group and normal control group (t= 13. 681, t= 9. 372, respectively, both P＜0. 01). And the level of serum VEGF was significantly higher in non-lung cancer group than in normal control group (t=5. 250, P＜0. 05). The level of serum endostatin was significantly higher in elderly long-term smokers with or without lung cancer than in normal control group (t=5. 332, t=3. 700, respectively, P＜0. 01 and P＜0.05). But there was no statistic difference between non-lung cancer group and lung cancer group (t = 0. 814, P＞ 0.05 ). Notably, the endostatin/VEGF ratio was lower in lung cancer group than in non-lung cancer group and normal control group (t= 6. 270, t= 7. 138, respectively, both P＜0.01), while there was no significant difference between non-lung cancer group and normal control group (t= 1. 022, P＞0.05). Conclusions These findings suggest that the periodic detection of serum VEGF and endostatin and endostatin/VEGF ratio, especially endostatin/VEGF ratio, is of clinical importance and can be used as an early diagnostic marker of lung cancer in elderly long-term smokers.
