Objective:To explore the characteristics of eosinophilic granulomatous polyangiitis (EGPA) and provide a basis for clinical diagnosis and treatment.Methods:A retrospective analysis was conducted on the epidemiology, clinical manifestations, laboratory tests, imaging and pathological characteristics, and treatment outcomes of 15 cases of eosinophilic granulomatous vasculitis.Results:Fifteen patients with eosinophilic granulomatous vasculitis were aged (50.7±17.2)years old, with a median time of 182.5 days from onset to diagnosis. Thirteen patients presented with respiratory symptoms as the initial diagnosis, while the other two presented with skin and nervous system damage. These patients were all accompanied by an increase in peripheral blood eosinophils, fluctuating between 10.6% and 60.94%. Thirteen patients had respiratory symptoms, mainly cough, sputum production, shortness of breath, and varied chest computed tomography (CT) findings. Histopathology or alveolar lavage fluid also showed changes in eosinophil count.Conclusions:The clinical manifestations of eosinophilic granulomatous vasculitis are diverse, often involving the respiratory system, as well as multiple systems such as the circulatory system, digestive system, nervous system, urinary system, and skin. However, due to its frequent early manifestations of wheezing, it is often misdiagnosed as refractory asthma. Improving the understanding of eosinophilic granulomatous vasculitis and improving the level of early diagnosis can help improve the prognosis of patients.

Objective: To investigate the impact of childhood traumatic experiences on individual risktaking decisions in early adulthood using functional nearinfrared spectroscopy (fNIRS), so as to provide the reference for clarifying the brain mechanisms underlying the impact of childhood trauma on individual risky decision. Methods: From December 2023 to March 2024, 28 children with childhood trauma experiences (trauma group) and 32 healthy college students (control group) were selected from Jining Medical University by a combination of stratified descent and convenient sampling methods. All subjects participated in the Iowa Game task fNIRS scanning. The brain activation, functional connectivity, graph theory properties (degree centrality, betweenness centrality, and local efficiency), and Receiver Operating Characteristic (ROC) analysis were performed by using preprocessing fNIRS data. Results: Compared with control group, trauma group showed significantly fewer choice times in the inferior deck (Z=-0.88), and showed significantly decreased activation levels in the right frontalpolar (Z=-2.59), as well as showed significant decreased functional connectivity between left dorsolateral prefrontal and in right dorsolateral prefrontal (Z=-3.78), and between left dorsolateral prefrontal cortex and the right frontal pole (Z=-3.68)(P<0.05). The central index of right inferior frontal gyrus in the trauma group was higher than that in the control group, while the central index of left and right dorsolateral frontal lobes was lower than that in the control group (Z=2.13, -2.53, -2.12, P<0.05). The centrality index of the right inferior frontal gyrus in the trauma group was higher than that in the control group (Z=2.47, P<0.05). The local efficiency indicators of the right inferior frontal gyrus, left and right frontal pole in the trauma group were higher than those in the control group (Z=2.51, 2.17, 2.53, P<0.05). The results of the ROC curve analysis showed that the local efficiency achieved the highest area under the curve (AUC=0.68). Conclusions Young adults with childhood trauma experience tend to choose lower loss, and the frontal pole shows a lack of activation in the whole process of risk decision performance. The abnormalities in the brain connectivity and network properties might be the neural basis of excessive defense mechanisms that childhood trauma leads to risky decisions.

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.

Improving the reproducibility of biomedical research results is a major challenge.Researchers reporting their research process transparently and accurately can help readers evaluate the reliability of the research results and further explore the experiment by repeating it or building upon its findings. The ARRIVE 2.0 guidelines, released in 2019 by the UK National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs), provide a checklist applicable to any in vivo animal research report. These guidelines aim to improve the standardization of experimental design, implementation, and reporting, as well as the reliability, repeatability, and clinical translatability of animal experimental results. The use of ARRIVE 2.0 guidelines not only enriches the details of animal experimental research reports, ensuring that information on animal experimental results is fully evaluated and utilized, but also enables readers to understand the content expressed by the author accurately and clearly, promoting the transparency and integrity of the fundamental research review process. At present, the ARRIVE 2.0 guidelines have been widely adopted by international biomedical journals. This article is a Chinese translation based on the best practices of international journals following the ARRIVE 2.0 guidelines in international journals, specifically for the complete interpretation of the ARRIVE 2.0 guidelines published in the PLoS Biology journal in 2020 (original text can be found at https://arriveguidelines.org). The third part of the article includes the items 8-10 of ARRIVE 2.0 Essential 10, which covers "experimental animals" "experimental procedures" and "results". Its aim is to promote the full understanding and use of the ARRIVE 2.0 guidelines by domestic researchers, enhance the standardization of experimental animal research and reporting, and promote the high-quality development of experimental animal technology and comparative medicine research in China.

OBIECTIVE To study the appearance characters, crystal morphology and trace element content of quartz from three different producing areas, in order to provide experimental basis for the processing and medicinal use of quartz. METHODS The crystal morphology and trace element contents of 23 quartz samples from Dachang Town, Qinglong County, Guizhou Province, Yata Town, Ceheng County, Guizhou Province and Badu Town, Tianlin County, Guangxi Zhuangzu Autonomous Region were studied by microscope and inductively coupled plasma mass spectrometry. OriginPro 2018 software was used for cluster analysis and multivariate principal component analysis of trace elements. RESULTS The white quartz in Badu area was mainly opalescent and lumpy coarse veined. Under the microscope, the white quartz was mainly granular and its surface was dark gray. In Dachang area, white quartz was often symbiosis with stibnite, and part of white quartz was light green. Under the microscope, white quartz was mainly veined and granular, and presents wavy extinction. The white quartz in Yata area was transparent and translucent, and the white quartz particles had a high degree of self-shape, and the white quartz surface could be seen grease luster. The common trace elements in white quartz included lithium(Li), aluminum(Al), titanium(Ti), vanadium(V), chromium(Cr), nickel(Ni), copper(Cu), zinc(Zn), gallium(Ga), arsenic(As), rubidium(Rb), strontium(Sr), yttrium(Y), antimony(Sb), barium(Ba), lead(Pb) and so on. The contents of trace elements in quartz from the three producing areas vary greatly, with the content ranging from lower than the instrument detection limit to 7 772.36 μg·g-1. The highest content was Al element. The contents of Al and Sb in white quartz from Dachang area were obviously higher than those in other areas, and the content of Al could reach 1 846.94-7 772.36 μg·g-1. CONCLUSION White quartz from the different regions of the morphology, microstructure, trace elements have obvious difference, in the same area of white quartz in trace elements has certain inner link, white quartz of Dachang area because contain higher content of neurotoxic element Al and heavy metal element Sb, so in the use of white quartz in the region should be considered as a source of medicinal materials.

Objective:To investigate the clinical and electrophysiological characteristics of facial onset sensory motor neuronopathy (FOSMN) syndrome.Methods:Ten patients diagnosed with FOSMN syndrome in Peking Union Medical College Hospital from January 2012 to December 2022 were included. The clinical and electrophysiological characteristics of patients were analyzed and summarized, and the genetic testing was also performed in these patients.Results:The age of onset was (56.6±6.5) years, and the longest survival duration of disease was 10 years. All patients had numbness around the face and mouth as the first symptom and abnormal blink reflex. A total of 52 sensory nerve conduction nerves were detected, among which 2 median nerves and 2 μlnar nerves showed decreased amplitude of sensory nerve action potential. Needle electromyography showed neurogenic lesions, with both progressive and chronic denervation. Whole exome sequencing identified the heterozygous variant c.272A>C in the exon 4 of the SOD1 gene resulting in the amino acid change p.Asp90Ala in 1 patient. In all patients, the disease progressed relentlessly and eventually led to involvement of respiratory muscle. Conclusion:FOSMN syndrome is characterized by abnormal blink reflex and sometimes abnormal sensory nerve conduction may be shown on electrophysiologic testing.

Objective:To report the clinical characteristics of a case of childhood amyotrophic lateral sclerosis (ALS) caused by SPTLC2 c.778G>A (p.Glu260Lys) mutation. Methods:Whole exon sequencing or whole genome sequencing data from 1 936 patients in the ALS cohort of Peking Union Medical College Hospital were screened for SPTLC2 gene mutations. Clinical data, laboratory examination, neurophysiological examination and genetic test results of the proband were collected. Results:Only one 9-year-old male child with SPLTC2 gene mutation was found. He was admitted to the Department of Neurology, Peking Union Medical College Hospital in December 2022 due to"progressive limb weakness for more than 4 years". Physical examination revealed atrophy and fasciculations of the tongue. Weakness of 4 limbs, muscle atrophy, as well as bilateral hyperreflexia, clonus, and Babinski sign were present. Whole genome sequencing indicated that SPTLC2 gene had c.778G>A (p.Glu260Lys) missense mutation, and no other pathogenic mutations of ALS related genes were detected. Sanger sequencing and family verification showed that neither father nor mother carried the mutation, suggesting that it was a de novo mutation. Nerve conduction velocity test showed no abnormalities, and electromyography suggested neurogenic lesions. Neurofilament light chain in cerebrospinal fluid and serum were increased significantly. The patient′s symptoms continued worsening even after oral administration of L-serine. Conclusion:SPTLC2 gene mutation can cause childhood ALS, and further study of its potential pathogenesis is helpful to uncover another potential pathway of ALS and a novel therapeutic target.

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). Participating institutions included Nanyang Central Hospital, Zhumadian Central Hospital, Luoyang Central Hospital, First Affiliated Hospital of Henan Polytechnic University, First Affiliated Hospital of Henan University, Luohe Central Hospital, the People's Hospital of Hebi, First People's Hospital of Shangqiu, Anyang Tumor Hospital, First People's Hospital of Pingdingshan, and Zhengzhou Central Hospital Affiliated to Zhengzhou University. 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.
