Objective:To describe demographic,clinical and physiological characteristics,treatment between first-episode major depressive disorder(MDD)and relapse MDD,and to explore characteristics of relapse MDD.Methods:Totally 858 patients who met the diagnostic criteria for depression of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5),were included by using the Mini International Neuropsychiatric Interview(MINI),Clinician-Rated Dimensions of Psychosis Symptom Severity,and Hamilton Depression Scale etc.Among them,529(58.6％)were first-episode depression and 329(36.0％)were relapsed.The differences of demographic characteristics,clinical and physiological characteristics,treatment were compared byx2test and Kruskal-Wallis rank sum test.Multivariate logistic regression was used to explore the characteristics of MDD recur-rence.Results:Compared to first-episode MDD,relapse MDD had more comorbidity(OR=2.11,95％CI:1.00-4.44),more days out of role(OR=1.26,95％CI:1.01-1.56),more history of using psychiatric drug more than one month(OR=1.41,95％CI:1.02-1.97)and electroconvulsive therapy(OR=3.23,95％CI:1.42-7.36),and higher waist-hip ratio(OR=33.88,95％CI:2.88-399.32).Conclusion:Relapse MDD has positive as-sociation with comorbidity of mental disorders,out of role,and higher waist-hip ratio.

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.

Background and objective Lung cancer is the cancer with the highest incidence and mortality rates in China,and non-small cell lung cancer(NSCLC)accounts for 80％-85％of all malignant lung tumors.Currently,surgical treat-ment remains the primary treatment modality for lung cancer.In recent years,the effectiveness of immune checkpoint inhibi-tors for NSCLC has become a consensus,and neoadjuvant immunochemotherapy(nICT)has shown promising efficacy and safety in early to intermediate stage NSCLC.However,there are fewer studies related to nICT for locally advanced NSCLC.This study aims to evaluate the efficacy and safety of nICT therapy in locally advanced resectable NSCLC.Methods 85 con-firmed resectable stage ⅢA and ⅢB patients treated in the Department of Thoracic Surgery,Second Hospital of Lanzhou University,from January 2021 to April 2024,were divided into the nICT group(n=32)and the surgery alone group(n=53).Clinical baseline data,perioperative indicators,postoperative complications,imaging response rate,pathological response rate,incidence of adverse events,and quality of life were compared between the two groups.Results There were no statisti-cally significant differences in clinical baseline data between the two groups(P＞0.05).Incidence of choosing thoracotomy was higher in the nICT group than in the surgery alone group(P=0.002).There were no significant differences in surgical time,intraoperative blood loss,number of dissected lymph nodes,duration of chest tube placement,postoperative hospital stay,and R0 resection rate between the two groups(P＞0.05).The overall incidence of postoperative complications was 31.25％in the nICT group and 22.64％in the surgery alone group,with no statistically significant difference(P=0.380).In the nICT group,the objective response rate(ORR)was 84.38％,with 5 cases of complete response(CR)(15.63％),22 cases of partial response(PR)(68.75％),15 cases of pathological response rate(pCR)(46.88％),and 11 cases of major pathological reaponse(MPR)(34.38％).During nICT treatment,12 cases(37.50％)experienced grade 3 treatment-related adverse events,no death induced by adverse events or immune related adverse events.Moreover,the symptoms of the patients were improved after nICT treat-ment.Conclusion Neoadjuvant immunochemotherapy shows promising efficacy in locally advanced resectable NSCLC,with manageable treatment-related adverse events.It is a safe and feasible neoadjuvant treatment modality for locally advanced resectable NSCLC.

Objective:To explore the effects of online mindfulness-based stress reduction(MBSR)on the anxiety and depression status,and quality of life in the caregivers of patients with severe mental disorders.Methods:Ninety-three caregivers for patients with schizophrenia or bipolar disorder,who were hospitalized in Yunnan Provincial Mental Hospital in March 2021,were enrolled and randomly divided into control group(n=47)and MBSR intervention group(n=46).Both groups received basic health education and rehabilitation skill training,while the intervention group received additional online MBSR for 8 weeks.The anxiety and depression status,and the quality of life of the caregivers were evaluated by Self-rating Anxiety Scale(SAS),Self-rating Depression Scale(SDS)and the 36-item Short Form Health Survey(SF-36)before and 8 weeks after intervention,respectively.Results:Thirteen caregivers dropped out of the study,and 80 subjects(40 in each group)were included in the final analysis.At the baseline,there were no significant differences in SAS,SDS and SF-36 scores between two groups(all P>0.05).Compared with the baseline,SAS and SDS scores in the intervention group significantly decreased after 8 weeks of intervention(both P<0.01)and were significantly lower than those in the control group(both P<0.01).There were no significant changes in the control group(all P>0.05).Except the physiological function dimension,the total score and the scores of each dimension of SF-36 in the intervention group were significantly increased after 8-week intervention(all P<0.05),and were significantly higher than those in the control group(all P<0.01).There were no significant changes in the control group before and after intervention(all P>0.05).Conclusion:Online MBSR can reduce the anxiety and depression levels,improve the quality of life in the caregivers of patients with severe mental disorders.

Acute necrotizing encephalopathy (ANE) is a rare but deadly complication with an unclear pathogenesis. We aimed to elucidate the immune characteristics of H1N1 influenza virusassociated ANE (IANE) and provide a potential therapeutic approach for IANE. Seven pediatric cases from a concentrated outbreak of H1N1 influenza were included in this study. The patients’ CD4+T cells from peripheral blood decreased sharply in number but highly expressed Eomesodermin (Eomes), CD69 and PD-1, companied with extremely high levels of IL-6, IL-8 in the cerebrospinal fluid and plasma. Patient 2, who showed high fever and seizures and was admitted to the hospital very early in the disease course, received intravenous tocilizumab and subsequently showed a reduction in temperature and a stable conscious state 24 h later. In conclusion, a proinflammatory cytokine storm associated with activated CD4+T cells may cause severe brain pathology in IANE. Tocilizumab may be helpful in treating IANE.

Objective:To explore the application effects of modified laparoscopic total extraperitoneal hernia repair (TEP) and laparoscopic transabdominal preperitoneal hernia repair (TAPP) in inguinal hernia.Methods:One hundred and twenty-five patients with inguinal hernia in Yiwu Central Hospital from February 2017 to December 2019 were selected for retrospective study. They were divided into modified TEP group (63 cases) and TAPP group (62 cases). The modified TEP group was treated with modified TEP, and the TAPP group was treated with TAPP. The perioperative operation related indexes, serum oxidative stress indexes, 1-year recurrence rate and semen quality indexes were compared between the two groups.Results:The scores of visual analogue scale after operation for 24 h in the modified TEP group was lower than that in the TAPP group: (1.68 ± 0.39) scores vs. (1.97 ± 0.46) scores, P<0.05. After operation for 3 d, the levels of serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) in the modified TEP group were higher than those in the TAPP group: (92.79 ± 8.82) μmol/L vs. (84.40 ± 7.36) μmol/L, (81.52 ± 9.37) U/L vs. (75.75 ± 8.50) U/L; and the level of malondialdehyde (MDA) in the modified TEP group was lower than that in the TAPP group: (23.42 ± 3.3) μmol/L vs. (26.71 ± 3.92) μmol/L; the differences were statistically significant ( P<0.05). There was no significant difference in 1-year recurrence rate between the two groups ( P>0.05). One year after operation, the levels of acid phosphatase (ACP), fructose (FRU) and α- glucosidase (α- Glu) in the modified TEP group were higher than those in the TAPP group: (180.87 ± 20.15) kU/L vs. (159.85 ± 14.50) kU/L, (3.37 ± 0.84) g/L vs.(2.53 ± 0.67) g/L, (62.94 ± 6.25) kU/L vs. (43.96 ± 5.31) kU/L, the differences were statistically significant ( P<0.05). Conclusions:Both modified TEP and TAPP are effective methods for the treatment of inguinal hernia, but the former can reduce surgical trauma, recover quickly, and protect normal reproductive function.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Objective:To evaluate the associations of meeting intensive systolic blood pressure (SBP) control goals with risk for incident cardiovascular and cerebrovascular diseases among the adult hypertensive patients in China.Methods:We used data from adult hypertensive patients from the China Kadoorie Biobank. logistic regression models evaluated the influencing factors of meeting intensive and standard SBP control goals. Cox proportional hazard models evaluated the associations between meeting intensive vs. standard SBP control goals and risk for incident cardiovascular and cerebrovascular diseases.Results:A total of 3 628 hypertensive patients who reported continuous medication use were included in this study, of which 5.0% of the participants met the goals of intensive SBP control (≤130 mmHg). Participants with higher educational attainment ( OR=2.36,95% CI: 1.32-4.04), healthier diet ( OR=2.09,95% CI: 1.45-2.96), daily intake of fresh fruit ( OR=1.67,95% CI: 1.17-2.36) and combination treatment ( OR=1.82,95% CI: 1.03-3.09) were more likely to meet intensive SBP control goal after adjustment of age, sex and urban/rural areas. During an average follow-up of (10.0±3.7) years, 1 278 cases of composite cardiovascular outcome were recorded. This study did not find a statistical correlation between achieving the goal of enhanced SBP control and the occurrence of composite cardiovascular and cerebrovascular outcomes ( HR=0.89, 95% CI: 0.63-1.25). For major adverse cardiovascular events (MACE), cerebrovascular diseases, stroke, and ischemic stroke, we observed a trend of decrease in risk of outcomes with more intensive SBP control (trend test P<0.05). Conclusions:We observed decreased risk for MACE and cerebrovascular diseases with more intensive SBP control. However, there was no significant risk reduction for cardiovascular and cerebrovascular diseases when meeting the intensive SBP control goal, compared to the standard SBP control goal.

Objective:To explore the feasibility of applying quantitative flow ratio(QFR) to assess the degree of coronary artery functional stenosis before surgery, and to guide coronary artery bypass grafting(CABG) revascularization strategy.Methods:The study prospectively included a total of 154 patients who were electively treated with CABG in the 11th ward of the Department of Cardiac Surgery of Beijing Anzhen Hospital from January 2019 to September 2020, and their coronary angiography visually showed stenosis of the coronary artery to perform QFR analysis to know the diseased blood vessels. For functional stenosis, the surgeon was blinded to the results of QFR analysis before surgery. Collect its baseline data, perioperative data and recent clinical outcomes for summary analysis.Results:One year later, the coronary artery CTA showed that the occlusion rate of functionally significant disease(QFR<0.8) was 5.5%, and that of non-functionally significant disease(QFR≥0.8) was 15.6%. There was no difference in angina class or repeat interventions between patients with or without occluded bypass grafts.Conclusion:According to QFR analysis, coronary arteries with functional non-significant disease have a higher risk of grafts failure than those with functionally significant disease. For coronary arteries with negative QFR lesions, the risk of occlusion of arterial grafts is higher than that of venous. However, this finding is not significantly related to clinical prognosis, because patients with patency or occlusion of the grafts in non-significant lesions have not found excessive angina pectoris or repeated coronary interventions. QFR-guided selection of coronary surgery strategies is safe and feasible.
