Beclin-1 is the firstly-identified mammalian protein of the autophagy machinery, which functions as a molecular scaffold for the assembly of PI3KC3 (class III phosphatidylinositol 3 kinase) complex, thus controlling autophagy induction and other cellular trafficking events. Notably, there is mounting evidence establishing the implications of Beclin-1 in diverse tumorigenesis processes, including tumor suppression and progression as well as resistance to cancer therapeutics and CSC (cancer stem-like cell) maintenance. More importantly, Beclin-1 has been confirmed as a potential target for the treatment of multiple cancers. In this review, we provide a comprehensive survey of the structure, functions, and regulations of Beclin-1, and we discuss recent advances in understanding the controversial roles of Beclin-1 in oncology. Moreover, we focus on summarizing the targeted Beclin-1-regulating strategies in cancer therapy, providing novel insights into a promising strategy for regulating Beclin-1 to improve cancer therapeutics in the future.

Object:To explore surgical treatments for duodenal fistula with intra-abdominal infection.Methods:The data of 19 patients with duodenal fistula treated at the Affiliated Tumor Hospital of Zhenzhou University between Jan 2015 and Dec 2021 were analyzed retrospectively. Surgery is performed with duodenostomy or modified duodenal shunt procedures.Result:All patients were accompanied by intra-abdominal infection, including 9 duodenal stump fistulas. All patients successfully completed the operation,11cases underwent duodenostomy, 8 case underwent modified duodenal shunt procedures. operating time was 110(60-140)min, postoperative hospitalization time was 29(9-103)d. Two patients died postoperatively. Fistula heals in other patients.Conclusion:Surgical intervention for duodenal fistula should focus on controlling the source of infection, strengthening intestinal and abdominal drainage, and reducing postoperative complications.

Objective:To investigate the effect of transorally inserted anvil (OrVil TM) in patients with relapsed or denovo carcinoma at the esophagogastric junction. Methods:The clinical data of 60 patients who underwent radical intent resection for locally relapsed or denovo esophagogastric junction adenocarcinoma at Zhengzhou University Cancer Hospital from Jan 2011 to Jun 2021 were retrospectively analyzed. The patients were divided into two groups according to whether transorally inserted anvil was used. Twenty-six patients who had used the system were assigned to the experimental group. Thirty-four patients without transorally inserted anvil were set to control group.Results:The incisor distance of the experimental group was shorter than that of the control group [36(34-40)cm vs. 39(36-41)cm, Z=-4.948, P<0.05]. Operation time in experimental group was 177 (145-260) min, compared to control group of 172 (140-225) min ( Z=-0.735, P=0.463). Intraoperative blood loss was 200 (100-900) ml in the experimental group and 300 (100-800) ml in the control group ( Z=-1.244, P=0.213). Postoperative upper margin distance of the experimental group was (3.6±1.7) cm compared to control group of (1.8±1.1) cm ( t=-0.735, P<0.01). The positive rate of margin in the experimental group was 4% vs. 15% in the control group ( χ2=1.931, P=0.165). The length of postoperative hospital stay in the experimental group was (18.6±5.2) d vs. (20.5±4.7) d ( t=-1.455, P=0.151). Surgery-related complications developed in 19% in the experimental group vs. 27% in the control group ( P>0.05). Conclusion:The application of the transorally inserted anvil in the operation of patients with locally relapsed or denovo esophagogastric junction cancer after initial operation reduces the difficulty of operation and decreases the positive rate of margin.

Objective: To investigate the proportion of achieving the blood lipid control target and its influencing factors among residents at a high risk of atherosclerotic cardiovascular disease (ASCVD), so as to provide insights into management of blood lipid among residents at a high risk of ASCVD. Methods: Residents at a high risk of ASCVD and at ages of 35 to 70 years were sampled using a multi-stage cluster sampling method from 6 counties (districts) in Shaoxing City from May to July 2021. The residents' demographics, smoking, alcohol consumption and medical history of chronic diseases were collected using questionnaires, the height, weight, waist circumference (WC) and blood pressure were measured, and the total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and fasting blood glucose were detected. The proportion of blood lipids achieving the control target was analyzed, and factors affecting the proportion of blood lipids achieving the control target were identified using a multivariable logistic regression model. Results: A total of 1 695 individuals at a high risk of ASCVD were enrolled, including 940 men (55.46%) and 755 women (44.54%), with a mean age of (62.56±6.08) years. There were 285 participants that achieved the target of blood lipid control (16.81%). Multivariable logistic regression analysis identified gender (male, OR=1.962, 95%CI: 1.396-2.758), age (OR=1.037, 95%CI: 1.013-1.061), WC (OR=0.979, 95%CI: 0.964-0.995), diastolic blood pressure (OR=0.981, 95%CI: 0.967-0.994), smoking (OR=1.485, 95%CI: 1.034-2.133), alcohol consumption (OR=0.684, 95%CI: 0.498-0.941), hypertension (OR=1.428, 95%CI: 1.006-2.207), administration of hypoglycemic drugs (OR=2.326, 95%CI: 1.720-3.144) as factors affecting the achievement of the target for blood lipid control among residents at a high risk of ASCVD. Conclusions Individuals at a high risk of ASCVD with higher WC, higher diastolic blood pressure and alcohol consumption are less likely to achieve the target for blood lipid control, while male individuals with older age, hypertension and administration of hypogcemic drugs are more likely to achieve the target for blood lipid control.

Intracranial atherosclerotic disease is one of the main causes of ischemic stroke. Imaging evaluation plays an important role in the formulation of treatment strategies. More and more studies have shown that the changes in hemodynamics after stenosis may have higher predictive value for stroke onset/recurrence compared to the degree of stenosis. This article reviews the evaluation of cerebral hemodynamics in intracranial atherosclerotic diseases.

Objective:To evaluate the safety of double and a half layered esophagojejunal anastomosis in radical gastrectomy.Methods:This prospective, multi-center, single-arm study was initiated by the Affiliated Cancer Hospital of Zhengzhou University in June 2021 (CRAFT Study, NCT05282563).

Inclusion criteria were as follows: (1) gastric adenocarcinoma confirmed by preoperative gastroscopy;(2) preoperative imaging assessment indicated that R0 resection was feasible; (3) preoperative assessment showed no contraindications to surgery;(4) esophagojejunostomy planned during the procedure; (5) patients volunteered to participate in this study and gave their written informed consent; (6) ECOG score 0–1; and (7) ASA score I–III. Exclusion criteria were as follows: (1) history of upper abdominal surgery (except laparoscopic cholecystectomy);(2) history of gastric surgery (except endoscopic submucosal dissection and endoscopic mucosal resection); (3) pregnancy or lactation;(4) emergency surgery for gastric cancer-related complications (perforation, hemorrhage, obstruction); (5) other malignant tumors within 5 years or coexisting malignant tumors;(6) arterial embolism within 6 months, such as angina pectoris, myocardial infarction, and cerebrovascular accident; and (7) comorbidities or mental health abnormalities that could affect patients' participation in the study. Patients were eliminated from the study if: (1) radical gastrectomy could not be completed; (2) end-to-side esophagojejunal anastomosis was not performed during the procedure; or (3) esophagojejunal anastomosis reinforcement was not possible. Double and a half layered esophagojejunal anastomosis was performed as follows: (1) Open surgery: the full thickness of the anastomosis is continuously sutured, followed by embedding the seromuscular layer with barbed or 3-0 absorbable sutures. The anastomosis is sutured with an average of six to eight stitches. (2) Laparoscopic surgery: the anastomosis is strengthened by counterclockwise full-layer sutures. Once the anastomosis has been sutured to the right posterior aspect of the anastomosis, the jejunum stump is pulled to the right and the anastomosis turned over to continue to complete reinforcement of the posterior wall. The suture interval is approximately 5 mm. After completing the full-thickness suture, the anastomosis is embedded in the seromuscular layer. Relevant data of patients who had undergone radical gastrectomy in the above 12 centers from June 2021 were collected and analyzed. The primary outcome was safety (e.g., postoperative complications, and treatment). Other studied variables included details of surgery (e.g., surgery time, intraoperative bleeding), postoperative recovery (postoperative time to passing flatus and oral intake, length of hospital stay), and follow-up conditions (quality of life as assessed by Visick scores).Result:[1] From June 2021 to September 2022,457 patients were enrolled, including 355 men and 102 women of median age 60.8±10.1 years and BMI 23.7±3.2 kg/m2. The tumors were located in the upper stomach in 294 patients, mid stomach in 139; and lower stomach in 24. The surgical procedures comprised 48 proximal gastrectomies and 409 total gastrectomies. Neoadjuvant chemotherapy was administered to 85 patients. Other organs were resected in 85 patients. The maximum tumor diameter was 4.3±2.2 cm, number of excised lymph nodes 28.3±15.2, and number of positive lymph nodes five (range one to four. As to pathological stage,83 patients had Stage I disease, 128 Stage II, 237 Stage III, and nine Stage IV. [2] The studied surgery-related variables were as follows: The operation was successfully completed in all patients, 352 via a transabdominal approach, 25 via a transhiatus approach, and 80 via a transthoracoabdominal approach. The whole procedure was performed laparoscopically in 53 patients (11.6%), 189 (41.4%) underwent laparoscopic-assisted surgery, and 215 (47.0%) underwent open surgery. The median intraoperative blood loss was 200 (range, 10–1 350) mL, and the operating time 215.6±66.7 minutes. The anastomotic reinforcement time was 2 (7.3±3.9) minutes for laparoscopic-assisted surgery, 17.6±1.7 minutes for total laparoscopy, and 6.0±1.2 minutes for open surgery. [3] The studied postoperative variables were as follows: The median time to postoperative passage of flatus was 3.1±1.1 days and the postoperative gastrointestinal angiography time 6 (range, 4–13) days. The median time to postoperative oral intake was 7 (range, 2–14) days, and the postoperative hospitalization time 15.8±6.7 days. [4] The safety-related variables were as follows: In total, there were 184 (40.3%) postoperative complications. These comprised esophagojejunal anastomosis complications in 10 patients (2.2%), four (0.9%) being anastomotic leakage (including two cases of subclinical leakage and two of clinical leakage; all resolved with conservative treatment); and six patients (1.3%) with anastomotic stenosis (two who underwent endoscopic balloon dilation 21 and 46 days after surgery, the others improved after a change in diet). There was no anastomotic bleeding. Non-anastomotic complications occurred in 174 patients (38.1%). All patients attended for follow-up at least once, the median follow-up time being 10 (3–18) months. Visick grades were as follows: Class I, 89.1% (407/457); Class II, 7.9% (36/457); Class III, 2.6% (12/457); and Class IV 0.4% (2/457).Conclusion:Double and a half layered esophagojejunal anastomosis in radical gastrectomy is safe and feasible.

Object:To investigate the impact of carbon nanoparticle tracing on the number of lymph nodes harvested in obese patients during radical gastrectomy for gastric cancer.Methods:Clinical data of 127 patients undergoing D 2 radical gastrectomy in the Affiliated Tumor Hospital of Zhengzhou University from Jan 2015 to Dec 2019 were retrospectively analyzed. According to whether the patients were injected with carbon nano particles during operation, they were divided into two groups: 64 patients without carbon nano particles during operation served as control group; 63 patients with carbon nano particles were included into experimental group. Results:The operation time of the control group was (160±31) min and that of the experimental group was (168±28) min ( t=-1.521, P=0.445). Intraoperative blood lose in the control group was (234±82) ml and that in the experimental group was (238±84) ml ( t=-0.295, P=0.846). The number of lymph nodes harvested in the first station, in the second station, the number of total lymph nodes and the number of lymph nodes with diameter <5 mm in the control group were less than those in the experimental group(10.4±3.8 vs. 24.5±10.6, t=-10.054),(6.6±2.8 vs. 16.8±7.3, t=-10.381),(17.1±6.4 vs. 41.2±17.6, t=-10.293),(3.9±2.5 vs. 21.2±9.1, t=-14.662) (all P<0.05), while the number of positive lymph nodes was not statistically different between the two groups all (5.9±6.2 vs. 4.2±3.4, t=-1.963, P>0.05). Black staining of lymph nodes in nano carbon group: 1 542 black stained lymph nodes were detected in the experimental group, the black staining rate of lymph nodes was 59.44% (1 542/2 594). Conclusion:Intraoperative application of carbon nanoparticles can significantly increase the number of harvested lymph nodes in obese (BMI≥25 kg/m 2) gastric cancer patients after radical resection.

Objective:To investigate the pathogenesis, selection of endovascular treatment (EVT) strategies, and efficacies of acute vertebrobasilar artery occlusion (AVBAO) of different lesion sites.Methods:One hundred and five patients with AVBAO, admitted to and accepted EVT in our hospital from February 2017 to September 2019, were chosen in our study. The data of disease onset, imaging findings, EVT status, perioperative complications, and prognoses of these patients were collected. According to DSA results, the involved lesions were divided into 4 sites: the upper segment of basilar artery (BA), the middle segment of BA, the lower segment of BA, and the intracranial segment of vertebral artery (V4 segment), and patients with tandem lesions would be recorded as distal lesions. The risk factors, EVT strategies, and prognoses 90 d after follow-up (modified Rankin scale [mRS] scores≤3: good prognosis) were compared in patients with 4 different lesion sites.Results:There were significant differences in etiological classifications and percentage of patients combined with atrial fibrillation among patients with 4 different lesion sites ( P<0.05). There was significant difference in proportion of patients accepted emergency stent implantation among patients with 4 different lesion sites ( P<0.05): those with lesions at the V4 segment had the highest proportion of patients accepted emergency stent implantation (79.55%), followed by those with lesions at the lower segment of BA (50.00%). There was significant difference in EVT time (the time from arterial puncture to successful recanalization of occluded vessels) among patients with 4 different lesion sites ( P<0.05): the EVT time in patients with lesions at the middle segment of BA was the shortest (87.5 [58.5, 130.8] min), and the EVT time in patients with lesions at the lower segment of BA was the longest (115.0 [81.0, 163.0] min). There was no statistical difference among patients with different lesion sites in good prognosis rate 90 d after follow-up ( P>0.05). Conclusion:The pathogenesis of patients with different AVBAO lesion sites is different, so different EVT strategies should be adopted.

Objective:To assess the role of arterial spin labeling (ASL) in detecting the blood-brain barrier (BBB) permeability of cerebral infarction lesions in patients with anterior circulation subacute ischemic stroke (SIS), and to evaluate the value of ASL in predicting hemorrhagic transformation (HT) of SIS patients after endovascular recanalization.Methods:A prospective analysis was performed. Patients with anterior circulation SIS who received endovascular treatment (EVT) in our hospital from January 2021 to September 2021 were enrolled. At 24 h before EVT and immediately after EVT, MRI scans of ASL sequences and dynamic contrast-enhanced magnetic resonance (DCE) sequence were completed, and Xper CT was performed; accordingly, imaging typing was performed. Head CT scan was performed 24-48 h after EVT to observe HT; according to the presence or absence of HT, these patients were divided into HT group and non-HT group; the relative cerebral blood flow (rCBF) values of ASL sequence parameters, volume transfer constant (K trans) of DCE sequence parameters and the differences of ASL, DCE and Xper CT imaging types between the two groups were compared. The weighted Kappa coefficient was used to test the consistency among ASL, DCE and Xper CT imaging types. Results:Among 22 eligible patients, 5 patients occurred HT (5/22, 22.72%). As compared with those in the non-HT group (1.14±0.04; 0.032[0.024, 0.039]/min), patients in the HT group had significantly higher rCBF value (1.57±0.18) and K trans (0.072[0.0455, 0.117]/min, P<0.05). There were significant differences in the distribution of ASL, DCE and Xper CT imaging types between the two groups ( P<0.05); among them, 4 out of 6 patients with ASL imaging type III, 4 out of 6 patients with DCE imaging type III, and 4 out of 5 patients with Xper CT imaging type III had HT. ASL sequence and DCE sequence had a high consistency in the imaging types (Kappa coefficient=0.941, 95%CI: 0.862-1.020, P<0.001). Conclusion:ASL can effectively evaluate the BBB permeability of cerebral infarction lesions in patients with anterior circulation SIS; patients with ASL imaging type III have a relatively high risk of HT.
