A 71-year-old male presented with esophageal cancer and severe aortic valve regurgitation. Treatment strategies for such patients are controversial. Considering the risks of cardiopulmonary bypass and potential esophageal cancer metastasis, we successfully performed transcatheter aortic valve implantation and minimally invasive three-incision thoracolaparoscopy combined with radical resection of esophageal cancer (McKeown) simultaneously in the elderly patient who did not require neoadjuvant treatment. This dual minimally invasive procedure took 6 hours and the patient recovered smoothly without any surgical complications.

Autophagy is the main degradation and recycling pathway for abnormal aggregates and damaged organelles in cells,and it maintains the normal metabolic balance and material renewal in cells.Autophagy has neuroprotective effects and can affect the functional state of the nervous system by regulating homeostasis,development,apoptosis,and other physiological processes of neurons and glial cells.In recent years,a large number of studies have shown that nervous system diseases are closely related to abnormal autophagy,and inhibition or overactivation of autophagy affects the occurrence and development of depression,neurodegenerative diseases,and schizophrenia.Understanding the mechanisms of autophagy in nervous system diseases is of great significance for their prevention and treatment.This paper mainly reviews the current progress of autophagy research and the above diseases of the nervous system,providing a reference for further research into these diseases.

The proportions of postoperative adjuvant therapy were 8.82%(21/238), 41.78%(89/213), 39.18%(143/365) in patients of low risk, moderate risk, high risk. Of 578 patients with moderate to high risk, the proportion of postoperative adjuvant therapy was 15.15%(5/33) in 2011, 14.71%(10/68)in 2012, 22.45%(11/49) in 2013, 29.09%(16/55) in 2014, 41.38%(24/58) in 2015, 46.15%(24/52) in 2016, 32.81%(21/64)in 2017, 60.00%(45/75) in 2018, 60.42%(29/48) in 2019, 61.84%(47/76) in 2020, respectively. Of 253 patients underwent postoperative adjuvant therapy, 247 cases received imatinib had 6 cases received sunitinib. (3) Comparison of clinicopathological characteristics of GIST with non-gastric origin and gastric origin. Of 847 patients, 262 cases had non-gastric origin and 585 cases had gastric origin. There were significant differences in gender, the number of tumor, tumor maximum diameter, Ki-67 index, risk classification of NIH, and R 0 resection between the two groups ( χ2=8.62, 8.40, 12.97, 6.57, Z=-6.15, χ2=17.19, P<0.05). (4) Analysis of influencing factors for recurrence-free survival rate in GIST patients. Results of multivariate analysis showed that the year of initial diagnosis, primary site, tumor maximum diameter, mitotic image, risk classification of NIH, R 0 resection, genetic testing and postoperative adjuvant therapy were independent factors influencing recurrence-free survival rate in GIST patients with initial surgical resection ( hazard ratio=0.58, 0.61, 2.00, 1.71, 5.81, 2.56, 0.65, 0.38, 95% confidence interval as 0.39-0.85, 0.45-0.83, 1.46-2.74, 1.24-2.35, 3.16-10.69, 1.63-4.02, 0.46-0.94, 0.25-0.56, P<0.05). Conclusions:GIST with initial surgical resection is common located in stomach, with high positive rate in CD117 and Dog-1. The number of people undergoing genetic testing and targeted therapy for GIST is increasing year by year. There are significant differ-ences in clinicopathological characteristics between GIST with non-gastric origin and gastric origin. The year of initial diagnosis, primary site, tumor maximum diameter, mitotic image, risk classifica-tion of NIH, R 0 resection, genetic testing and postoperative adjuvant therapy are independent factors influencing recurrence-free survival rate in GIST patients with initial surgical resection.

Objective To investigate the effect of orthokeratology combined with repeated low-level red-light(RL-RL)therapy on progressive myopia in adolescents.Methods A total of 106 adolescents(212 eyes)with progressive my-opia admitted to our hospital from March 2020 to September 2022 were selected and randomly classified into an observation group(n=57,114 eyes)and a control group(n=49,98 eyes).Patients in the observation group received orthokeratology and RLRL therapy,and patients in the control group received orthokeratology only.All patients were followed up for 1 year.The uncorrected visual acuity(UCVA),axial length(AL),diopter,tear film lipid layer thickness(LLT),break-up time(BUT),subfoveal choroidal thickness(SFChT),and the incidence of complications at different time points were compared between the two groups.Results Analysis of variance on the UCVA,diopter,LLT,BUT and SFChT at differ-ent time points before and after treatment revealed a significant time effect and time × group interaction effect(all P＜0.05),but no statistical group effect(all P＞0.05).For the AL,there was a significant time effect(P＜0.05),but no time x group interaction effect or group effect(all P＞0.05).Twelve months after treatment,the UCVA,LLT decrease and SFChT thickening were greater in the observation group compared to the control group,while the diopter progression and AL increase were milder in the observation group than in the control group(all P＜0.05).Changes in BUT yielded no sta-tistical difference between the two groups(P＞0.05).The complication rate demonstrated no statistical difference between the two groups(P＞0.05).Conclusion The application of RLRL therapy combined with orthokeratology for progressive myopia in adolescents can effectively improve the UCVA and control the growth of AL and diopter,with high safety.

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.
