Objective:To evaluate the efficacy of ultrasound-guided subcostal quadratus lumborum block combined with general anesthesia in laparoscopic bariatric surgery.Methods:In this prospective randomized controlled study, 80 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱpatients, aged 18-40 yr, with a body mass index of 30-45 kg/m 2, of cardiac function classification Ⅰ or Ⅱ, who underwent laparoscopic bariatric surgery at the First Affiliated Hospital of Nanjing Medical University from February 2023 to May 2023, were selected and divided into 2 groups ( n=40 each) using a table of random numbers: general anesthesia group (GA group) and subcostal quadratus lumborum block combined with general anesthesia group (SQB+ GA group). Both groups received combined intravenous-inhalational anesthesia. Patients in SQB+ GA group underwent bilateral ultrasound-guided subcostal quadratus lumborum block with 20 ml of 0.375% ropivacaine before anesthesia induction. Oxycodone was administered for analgesia during the post-anesthesia care unit (PACU) stay. Patient-controlled intravenous analgesia with sufentanil and granisetron was used after returning to the ward. When the visual analog scale score >4 within 24 h after surgery, flurbiprofen axetil 50 mg was intravenously given as rescue analgesic. The intraoperative consumption of remifentanil and use of vasoactive drugs were recorded. The effective pressing times of patient-controlled analgesia and requirement for rescue analgesia were recorded. The tracheal extubation time, PACU stay time, use of oxycodone during PACU stay, and occurrence of hypoxemia after tracheal extubation and occurrence of adverse reactions within 24 h after surgery was also recorded. Arterial blood gas analysis was performed at discharge from PACU. Results:Compared with GA group, the intraoperative consumption of remifentanil was significantly reduced, the usage rate of oxycodone, effective pressing times of patient-controlled analgesia and rate of rescue analgesia were significantly decreased, the PaO 2 and PaCO 2 at discharge from PACU were decreased, the tracheal extubation time and PACU stay time were shortened, and the incidence of hypoxemia after tracheal extubation and postoperative nausea and vomiting was decreased in SQB+ GA group ( P<0.05). Conclusions:Compared with general anesthesia alone, ultrasound-guided subcostal quadratus lumborum block combined with general anesthesia can reduce the intraoperative consumption of opioids, alleviate postoperative pain, and decrease the occurrence of postoperative adverse reactions when used in laparoscopic bariatric surgery.

Objective: To identify biomolecular markers closely related to the occurrence of kidney renal clear cell carcinoma (KIRC) and verify their expression levels in clinical samples. Methods: Stage Ⅰ KIRC mRNA sequencing data were obtained from The Cancer Genome Atlas (TCGA).Principal component analysis (PCA) was used for dimensionality reduction to screen differentially expressed genes (DEGs)，which then underwent GO and KEGG analyses.Weighted gene co-expression network analysis (WGCNA) was used to screen genes significantly related to KIRC，and a protein-protein interaction (PPI) network was constructed to screen hub genes.The diagnostic value of hub genes was evaluated with receiver operating characteristic (ROC) curve，and their prognostic value was analyzed using survival curve plots.The correlation between the mRNA expressions of hub genes and the pathological stages of KIRC was analyzed.Clinical samples of 20 patients with stage Ⅰ KIRC treated in our hospital were included，and the expressions of the hub genes in cancerous and adjacent tissues were detected with reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR)，Western blotting，and enzyme-linked immunosorbent assay (ELISA). Results: A total of 8223 DEGs were screened out，including 4092 up-regulated ones and 4131 down-regulated ones.GO analysis showed that DEGs were related to bioadhesion，plasma membrane composition，and transporter activity.KEGG analysis showed that DEGs were related to pathways such as cell adhesion molecules，cytokine-cytokine receptor interactions，and interactions between viral proteins and cytokines and cytokine receptors.WGCNA analysis obtained 171 genes that were significantly related to stage Ⅰ KIRC.The hub gene，lymphocyte cytosolic protein 2 (LCP2)，screened out by the PPI network，was significantly related to stage Ⅰ KIRC.The area under the ROC curve was 0.96.The expression level was negatively correlated with the overall survival rate of patients.The expression of LCP2 was related to the stage and lymph node metastasis.Clinical verification showed that the mRNA and protein relative expressions of LCP2 in KIRC tissues were significantly higher than those in adjacent tissues (P<0.000 1). Conclusion: LCP2 is significantly up-regulated in stage Ⅰ KIRC tissues and can be used as a potential biomarker for the early diagnosis and treatment of KIRC.

Coronavirus disease 2019 (COVID-19) is a multi-system disease that can lead to various severe complications. Acute limb ischemia (ALI) has been increasingly recognized as a COVID-19-associated complication that often predicts a poor prognosis. However, the pathophysiology and molecular mechanisms underlying COVID-19-associated ALI remain poorly understood. Hypercoagulability and thrombosis are considered important mechanisms, but we also emphasize the roles of vasospasm, hypoxia, and acidosis in the pathogenesis of the disease. The angiotensin-converting enzyme 2 (ACE2) pathway, inflammation, and platelet activation may be important molecular mechanisms underlying these pathological changes induced by COVID-19. Furthermore, we discuss the hypotheses of risk factors for COVID-19-associated ALI from genetic, age, and gender perspectives based on our analysis of molecular mechanisms. Additionally, we summarize therapeutic approaches such as use of the interleukin-6 (IL-6) blocker tocilizumab, calcium channel blockers, and angiotensin-converting enzyme inhibitors, providing insights for the future treatment of coronavirus-associated limb ischemic diseases.

Objective:To investigate the current situation of uncivilized behavior in workplace encountered by nurses in Xianyang City, and analyze its influencing factors, so as to provide a basis for formulating corresponding intervention measures.Methods:In May 2023, convenience sampling was used to investigate the general information, current situation of uncivilized behavior in workplace and coping style of 1310 nurses in 8 secondary and tertiary general hospitals in Xianyang City by using the general information questionnaire, the Chinese version of the Nurse Incivility Scale and the Simplified Coping Style Questionnaire. Multiple linear regression analysis was used to analyze the influencing factors of uncivilized behavior encountered by nurses.Results:A total of 1285 valid questionnaires were collected, with an effective recovery rate of 98.09%. The total score of uncivilized behavior encountered by nurses was (86.41±22.49) points. Among them, the scores of five dimensions were nurses' uncivilized behavior (19.95±4.70) points, patients' uncivilized behavior (23.66±8.96) points, supervisors' uncivilized behavior (13.25±4.87) points, doctors' uncivilized behavior (14.32±5.63) points and colleagues' uncivilized behavior (15.23±4.93) points. The multiple linear regression analysis results showed that the hospital level and coping style were the significant influencing factors of uncivilized behavior in workplace encountered by nurses ( β=0.104, 0.056; P<0.05) . Conclusion:The current situation of uncivilized behavior in workplace encountered by nurses needs to be improved. Hospital managers should focus on coping styles, such as setting up simulation scene exercises, team cooperation training, training and counseling, so as to reduce the uncivilized behavior in workplace encountered by nurses.
