During the Yan’an period， the party and government employed forms of health propaganda that were popular among the masses， focusing on superb medical skills and public feedback， as well as the strategy of skillfully using narrative techniques to carry out doctor-patient communication， which collectively created the image of good doctors characterized by “firm belief， superb medical skills， effective communication， and a friendly and approachable demeanor.” They were not only guardians of the people’s health but also the solid pillars of the success of the revolutionary cause. In the journey of the new era， contemporary medical professionals should deeply grasp the spiritual core of good doctors in the Yan’an period， uphold the leadership of the Communist Party of China， harbor a benevolent heart， and earn the trust and respect of patients through sincere humanistic care and superb medical services， so as to collectively promote the development of medical undertakings and contribute their strength to building a healthy China.

Gastric cancer is a malignant tumor of the digestive system with strong invasiveness and a high metastasis rate.Its morbidity and mortality rank among the top five in the world and the prognosis is closely related to the disease stage.Multidisciplinary comprehensive treatment based on systemic antitumor drugs is generally adopted in patients with advanced or metastatic gastric can-cer,but the prognosis is typically poor.With the in-depth research on the tumor microenvironment,the development of multi-omics technology,and the application of immunotherapy and neoadjuvant chemoradiotherapy,the therapeutic effect of advanced gastric can-cer has been initially improved,and immunotherapy has become the most potential of the treatment strategies.Many studies have found that Helicobacter pylori(Hp)infection status is closely related to the efficacy of immunotherapy for gastric cancer,especially im-mune checkpoint inhibitors(ICIs),but there is not clear whether it has advantages or disadvantages.This article reviews the current research on the efficacy of Hp on ICIs in advanced gastric cancer to provide ideas for further research on the interaction between Hp in-fection and tumor immunotherapy.

Objective:To explore the feasibility and value of performing a three-sided encapsulation procedure based on fascia anatomy in laparoscopic lateral lymph node dissection (LLND) for middle and low rectal cancer.Methods:This was a retrospective review. The study cohort comprised patients who met the diagnostic criteria for rectal cancer according to the Chinese Guidelines for the Diagnosis and Treatment of Colorectal Cancer, had a short lymph node diameter of >5 mm on the lateral side within the 15 days before surgery, were evaluated as feasible candidates for laparoscopic total mesorectal excision+LLND surgery, had been diagnosed with low or intermediate level rectal cancer, and whose tumor was less than 8 cm away from the anal verge according to pathological examination of the operative specimen. Patients with a history of other malignant tumors of the abdomen or with incomplete follow-up data were excluded. Forty-two patients with middle and low rectal cancer who had undergone lateral lymph node dissection in diagnosis and treatment center of Gastrointestinal Cancer of Guangdong Hospital of Chinese Medicine from Jan.2018 to Dec.2022 were enrolled. There were 24 men (57.1%) and 18 women (42.9%) aged 58.4±11.8 years and the median BMI was 22.5 (19.3–24.1) kg/m 2. The main point of the three-sided encapsulation procedure is to expand the external side medial to the external iliac artery and vein, narrowing the range of exterior side dissection. The anterior-medial side is designed to expand the vesical fascia to define the range of anterior-medial side extension. The internal side is fully extended to the ureterohypogastric nerve fascia; the distal point of the caudal extension reaches the level of the Alcock canal and the bottom reaches the piriformis, enabling dissection of the obturator nerve and No.283 lymph nodes. No.263D lymph nodes are dissected by exposing the internal iliac artery and its branches, dissecting the group No.263P lymph nodes, and severing the inferior vesical artery. Finally, the lateral lymphatic tissue is completely resected. Relevant variables were recorded, including the number of lateral lymph nodes detected, the rate of lymph node metastasis, operation duration, intraoperative blood loss, postoperative complications, postoperative hospital stay, and 3-year overall survival rate. Results:Laparoscopic surgery was successfully completed in all patients with no conversions to open surgery and no intraoperative complications. Twenty-seven (64.3%) of the study patients underwent left-sided LLND, 10 (23.8%) right-sided LLND, and five (11.9%) bilateral LLND, with lymph nodes cleared on both sides. All patients' lymph nodes were examined pathologically. A median of 17.0 (11.7, 26.0) lymph nodes was detected, the median of lateral lymph nodes being 5.0 (2.0, 10.2). The median operation time was 254.5 (199.0, 325.2) minutes. The median intra-operative blood loss was 50.0 (30.0, 100.0) mL. All patients were diagnosed with adenocarcinoma by pathological examination of the operative specimen. Two patients developed postoperative intestinal obstruction, one lymphatic leakage, and one a perineal incision infection. There were no cases of anastomotic leakage. The median postoperative hospital stay was 6.0 (5.0, 7.0) days and the median follow-up time 23.5 (9.0, 36.7) months. During follow-up, three patients (7.1%) died of tumor recurrence and metastasis. Two (4.8%) experienced mild urinary dysfunction, and one (2.4%) had moderate postoperative erectile dysfunction. One patient (2.4%) was found to have prostate and lung metastases 3 month after surgery. The 3-year overall survival rate was 74.4%.Conclusions:Three sided encapsulation is a safe and feasible procedure for LLND, achieving accurate and complete clearance of lateral lymphatic tissue.

Objective:To investigate the efficacy and safety of retroperitoneal soft tissue sarcoma resection combined with nephrectomy.Methods:The clinical data of 27 cases undergoing retroperitoneal soft tissue sarcoma resection combined with nephrectomy at the Gastrointestinal Tumor Center , Guangdong Provincial Hospital , Traditional Chinese Medicine from Jun 2017 to Aug 2022 were retrospectively analyzed for the indication of nephrectomy, postoperative progression of renal insufficiency and survival rate.Results:Twenty-six cases (96%) achieved R 0/R 1 resection and 1 case nderwent R 2 resection. Six cases underwent combined unilateral nephrectomy and 21 patients underwent combined multi-organ resection with a median number of resections of 4 (2,5). Postoperative pathology suggested that the combined resected kidney was positive for tumor infiltration in 17 cases. Five cases had Clavien-Dindo grade 3 or higher complications and no deaths occurred within 30 days after surgery. At the 90th day after surgery, 19 cases (70%) had decreased renal function ( Z=2.88, P=0.04), with a median decrease of -3.96 (-30.36, 0.31)ml·(min·1.73 m 2) -1, including 8 cases of preoperative Chronic Kidney Disease(CKD)1 stage progression (6 cases of CKD 2 stage, 2 cases of CKD 3 stage); 2 cases of CKD 2 stage progressed to CKD 3 stage; 1 case of preoperative CKD 3 stage progressed to CKD 4 stage. During the follow-up period of 3-38 months, no patient progressed to CKD 5 stage and no patient required dialysis treatment. Conclusion:Retroperitoneal soft tissue sarcoma resection combined with nephrectomy is safe and feasible while improving tumor radicality.

【Objective】 To investigate the relationship between the level of thrombin-antithrombin complex (TAT)/α2-plasmin inhibitor-plasmin complex (PIC) and the utilization rate of mechanical ventilation (MV) in critically ill patients. 【Methods】 For the cross-sectional study, adult patients who had been admitted to the intensive care unit (ICU) for one day or longer and had a record of the first four tests for thrombosis were enrolled. Age, gender, the results of TAT and PIC, disseminated intravascular coagulation score, treatment, and diagnostic information were retrospectively collected from the hospital information system and laboratory information system. Logistic regression model was used to explore the relationship between TAT/PIC and the MV utilization rate. Interaction analysis and subgroup analysis were conducted to explore whether there was any difference between patients with different age and gender, patients with/without DIC, and with/without infection. 【Results】 A total of 1 176 patients were enrolled in this study. The median of the first TAT/PIC was 15.84 (8.13-33.11) in all the patients. The multivariable Logistic regression model results showed that for every 5 increase in TAT/PIC, the possibility of using MV increased by 2.9% (OR=1.029, 95% CI: 1.008-1.050), and the possibility of using MV in Q3 patients was 1.566 times than that in Q1 patients (OR=1.566, 95% CI: 1.095-2.239); the possibility of using MV in Q4 patients was 2.457 times than that in Q1 patients (OR=2.457, 95% CI: 1.694-3.563). Interaction results showed that the relationship between the level of TAT/PIC and MV usage was different in patients with and without infection (Pinteraction=0.02). Further subgroup analysis showed that in the infected patients (674 cases), the possibility of using MV increased by 5.9% for every 5 increase in TAT/PIC (OR=1.059, 95% CI: 1.022-1.097, P=0.001), while there was no significant difference between different TAT/PIC and MV usage in non-infected patients (502 cases) (OR=1.012, 95% CI: 0.984-1.040, P=0.405). 【Conclusion】 There is a correlation between the level of TAT/PIC and mechanical ventilation in patients with infection in the ICU.

Objective: To investigate the effect of circadian heart rate variation on short-term and long-term mortality in intensive care unit (ICU) patients. Methods: A retrospective cohort study was conducted. A total of 32 536 ICU patients were recorded from 2001 to 2008 published by Multiparameter Intelligent Monitoring in Intensive Care Ⅱ (MIMIC-Ⅱ v2.6) in April 2011. The circadian heart rate variation was defined as the ratio of mean nighttime (23:00 to 07:00) heart rate to mean daytime (07:00 to 23:00) heart rate. The 28-day mortality and 1-year mortality were defined as outcome events. The information such as age, gender, ethnicity, first sequential organ failure assessment (SOFA) score, first simplified acute physiology score Ⅰ (SAPSⅠ), usage of sedatives and catecholamines within 24 hours admission of ICU, clinical complications [hypertension, chronic obstructive pulmonary disease (COPD), diabetes with or without complications, congestive heart failure, liver disease, renal failure, etc.], and the complete heart rate records within 24 hours after ICU admission were collected. Cox proportional risk regression models were used to investigate the association between circadian heart rate variation and 28-day mortality and 1-year mortality in ICU patients. Besides, subgroup analysis was also performed in patients with different first SOFA scores. Results: Totally 15 382 ICU patients in MIMIC-Ⅱ database were enrolled, excluding the patients without heart rate records or death records, using pacemaker with arrhythmia, without SOFA or SAPSⅠ score records. Finally, 9 439 patients were enrolled in the study cohort. ① Cox regression analysis of the whole patient showed that the higher circadian heart rate variation was correlated with the increased 28-day mortality [hazard ratio (HR) = 1.613, 95% confidence interval (95%CI) was 1.338-1.943, P < 0.001] and 1-year mortality (HR = 1.573, 95%CI was 1.296-1.908, P < 0.001). After adjustment for demographic factors (age, gender and ethnicity), severity of illness (SOFA and SAPS Ⅰ scores), clinical complications (hypertension, COPD, diabetes with or without complications, congestive heart failure, liver disease, renal failure, etc.), and influence of medications (sedatives and catecholamines), the night-day heart rate ratio was also correlated with 28-day mortality (HR = 1.256, 95%CI was 1.018-1.549, P = 0.033) and 1-year mortality (HR = 1.249, 95%CI was 1.010-1.545, P = 0.040). ② According to the SOFA score (median value of 5), the patients were divided into two subgroups, in which 5 478 patients with SOFA score ≤ 5 and 3 961 patients with SOFA score > 5. Cox regression subgroup analysis showed that circadian heart rate variation was related with higher 28-day mortality (HR = 1.430, 95%CI was 1.164-1.756, P = 0.001) and 1-year mortality (HR = 1.393, 95%CI was 1.123-1.729, P = 0.003) in patients with SOFA score > 5. After adjustment for covariates, the 28-day mortality (HR = 1.279, 95%CI was 1.032-1.584, P = 0.025) and 1-year mortality (HR = 1.255, 95%CI was 1.010-1.558, P = 0.040) also increased with the increasing of night-day heart rate ratio in patients with SOFA score > 5. However, the relationships did not exist in patients with SOFA score ≤ 5. Conclusion In ICU patients, the 28-day mortality and 1-year mortality increase with the higher circadian heart rate variation, which indicates that the circadian heart rate variation in ICU patients is positively correlated with the short-term and long-term mortality, especially in patients with relatively severe illness.
