Robot-assisted surgery with its advantages such as three-dimensional high-definition vision, dexterous robotic arms, and tremor filtration, is increasingly being applied to complex radical gastrectomy. However, the role of the surgical assistant remains crucial during the procedure. The assistant is responsible for tasks outside the console, including adjusting robotic arms, changing instruments, exposing the surgical field, and addressing unexpected situations. The technical proficiency of the assistant and their collaboration efficiency with the primary surgeon directly impact the smoothness of surgery and patients' outcomes. With the expansion of robot-assisted surgical indications, the establishment of a standardized training system and the optimization of team collaboration models have become urgent challenges to address. This article draws on the author's practical experience as an assistant in robot-assisted gastric cancer surgeries, conducting an in-depth analysis of the responsibilities and operational skills of surgical assistants in robot-assisted procedures. The aim is to develop a relatively comprehensive set of operational guidelines for surgical assistants in robot-assisted radical gastrectomy, providing valuable references for enhancing the overall efficiency of surgical teams and improving surgical outcomes.

Objective:The purpose of this study was to develop a dynamic prediction model for patients with gastric signet ring cell cancer (GSRCC)following laparoscopic radical gastrectomy in order to improve the precision and usefulness of prognoses prediction for overall survival and disease-free survival.Methods:From 2011 to 2018, 914 National Cancer Center patients participated in the study. To find independent prognostic indicators and create a prognostic nomogram model, univariate and multivariate regression analyses were performed. Calibration curves, receiver operating characteristic curves, and consistency indices were used to assess the model's performance. To make clinical application more convenient, two web-based prediction tools were created.Results:A training set of 639 cases and a validation set of 275 instances were randomly selected from among the patients. Important predictive variables such as age, tumor size, location, pN and pT staging, and postoperative chemotherapy were all incorporated in the model (all P<0.05). The model's consistency index and area under the receiver operating characteristic curves were both higher than 0.7, and the calibration curves demonstrated a good fit between the expected and actual values, indicating high accuracy and consistency in postoperative survival prediction for patients with gastric signet ring cell carcinoma. Conclusion:We successfully developed two dynamic prediction models in this study, which improved its clinical practicability using web-based tools and is anticipated to be crucial to clinical practice going forward.

This study explores the diagnosis and treatment of needle knife therapy for ankylosing spondylitis (AS) at middle and advanced stage based on the theory of meridian tendons, from a holistic perspective and syndrome differentiation. The treatment strategy includes "harmonizing yin and yang" to address root causes and "tendons-based release" to harmonize qi and blood, with the "tendons nodule points" as the core acupoint selection criterion. Based on this approach, the study systematically elaborates on two needle knife methods for AS: "governor vessel bone-piercing technique" and "below-the-umbilicus release technique", covering indications, acupoint location, and procedures. Clinical case examples are provided to enrich needle knife therapy guided by the theory of meridian tendons, offering insights for clinical and research work on AS.

Objective:To evaluate the association between septic shock and tracheal injury in the intensive care unit (ICU) patients with invasive ventilation.Methods:This was a prospective single-centre cohort study. Patients who underwent invasive mechanical ventilation at the Department of Anesthesia Critical Care Medicine of the Second Hospital of Hebei Medical University from May 31, 2020 to March 5, 2022 were selected. The general characteristics of patients, reasons for ICU admission, vital signs, laboratory test results, Acute Physiology and Chronic Health Evaluation Ⅱ scores, Charlson Comorbidity Index, size of endotracheal tube, presence or absence of septic shock, oxygenation index, duration of intubation, consumption of norepinephrine and epinephrine, and tracheal injury scores at the time of extubation were recorded. Univariate linear regression analysis was used to identify the risk factors for tracheal injury, followed by adjustment using multivariate linear regression analysis.Results:Ninety-seven patients were ultimately included, and the average age was (56.6±16.5) yr, with 64.9% being male. The results of adjusted linear regression showed that septic shock was associated with tracheal injury scores ( β=2.99, 95% confidence interval 0.70-5.29). Subgroup analysis revealed a stronger correlation with a duration of intubation≥8 days ( P=0.013). Conclusions:Patients with septic shock exhibit significantly higher tracheal injury scores compared with those without septic shock, suggesting that septic shock may serve as an independent risk factor for tracheal injury.

Objective To investigate the impact of dexamethasone(DEX)on diaphragmatic atrophy caused by acute respiratory distress syndrome(ARDS)and its correlation with diaphragmatic protein metabolism.Methods Twenty healthy male Sprague-Dawley(SD)rats were randomly assigned to control,ARDS model,low-dose DEX,and high-dose DEX group,with each group consisting of five rats.ARDS was induced in the rats by intratracheal administration of lipopolysaccharide(LPS)at 4 mg/kg.Conversely,intratracheal saline was administered to the control group at 2 mL/kg.Following the induction of the model,an intraperitoneal injection of DEX at 1 mg·kg-1·d-1 was administered to the low-dose DEX group.Conversely,DEX at 5 mg·kg-1·d-1 was administered to the high-dose group for 7 consecutive days.Subsequently,on the eighth day of the experiment,the diaphragmatic weight of all rats was measured.Real-time quantitative polymerase chain reaction(PCR)was utilized to assess the mRNA expression of interleukins(IL-1β,IL-18)in each group.Western blotting was employed to determine the protein expression levels of nuclear factor-κB(NF-κB)p65,NOD-like receptor protein 3(NLRP3),caspase-1,Gasdermin D(GSDMD),myosin heavy chain 2(Myh2),and F-box protein 32(Fbxo32).Additionally,immunohistochemistry was utilized to evaluate the ratio of fast to slow muscle fibers in the diaphragm.Results The ARDS model group showed significant reductions in body weight,diaphragm weight,fast muscle fibers,and Myh2 protein expression compared to the control group[body weight(g):266±17 vs.292±15,diaphragm weight(g):0.77±0.02 vs.0.92±0.08,fast muscle fibers:(74±1)%vs.(78±3)%,Myh2 protein expression(Avalue):0.75±0.07 vs.0.95±0.05,all P<0.05].Conversely,significant increases were observed in the expressions of IL-1β and IL-18 mRNA,slow muscle fibers,and the proteins NF-κB p65,NLRP3,caspase-1,GSDMD,Fbxo32[IL-1β mRNA(IL-1β/GAPDH):2.2±0.3 vs.1.0±0.2,IL-18 mRNA(IL-18/GAPDH):2.3±0.3 vs.1.0±0.3,slow muscle fibers:(26±1)%vs.(22±3)%,NF-κB p65 protein expression(A value):0.40±0.15 vs.0.17±0.05,NLRP3 protein expression(A value):0.51±0.05 vs.0.27±0.08,caspase-1 protein expression(A value):0.54±0.12 vs.0.30±0.19,GSDMD protein expression(A value):0.40±0.12 vs.0.20±0.05,Fbxo32 protein expression(A value):0.51±0.15 vs.0.33±0.08,all P<0.05].Compared with the ARDS group,both low and high doses of DEX were found to further reduce body weight,diaphragm weight,fast muscle fibers,and Myh2 protein expression,and further increase the expressions of IL-1β and IL-18 mRNA,slow muscle fibers,and the proteins NF-κB p65,NLRP3,caspase-1,GSDMD,Fbxo32,with the changes in the high dose DEX group being more significant than those in the low dose group[body weight(g):198±14 vs.222±16,diaphragm weight(g):0.57±0.04 vs.0.68±0.04,fast muscle fibers:(56±5)%vs.(69±2)%,Myh2 protein expression(A value):0.29±0.16 vs.0.57±0.15,IL-1βmRNA expression:5.6±1.4 vs.3.3±0.6,IL-18 mRNA expression(IL-18/GAPDH):5.8±1.2 vs.3.9±0.6,slow muscle fibers:(44±5)%vs.(31±2)%,NF-κB p65 protein expression(A value):0.87±0.04 vs.0.70±0.07,NLRP3 protein expression(A value):0.75±0.08 vs.0.63±0.04,caspase-1 protein expression(A value):0.99±0.06 vs.0.82±0.08,GSDMD protein expression(Avalue):0.85±0.11 vs.0.61±0.10,Fbxo32 protein expression(Avalue):1.00±0.10 vs.0.78±0.12,all P<0.05].Normal muscle fiber structure was revealed by microscopic observation in the control group,clear fiber separation in the ARDS model group,and disordered muscle fiber arrangement with structural distortion was noted in both low and high-dose DEX groups.Conclusion Prolonged administration of DEX may worsen diaphragmatic atrophy induced by ARDS,possibly by promoting the activation of the NLRP3 inflammasome and cell pyroptosis.
