Research indicates that microbe activity within the human body significantly influences health by being closely linked to various diseases. Accurately predicting microbe-disease interactions (MDIs) offers critical insights for disease intervention and pharmaceutical research. Current advanced AI-based technologies automatically generate robust representations of microbes and diseases, enabling effective MDI predictions. However, these models continue to face significant challenges. A major issue is their reliance on complex feature extractors and classifiers, which substantially diminishes the models' generalizability. To address this, we introduce a novel graph autoencoder framework that utilizes decoupled representation learning and multi-scale information fusion strategies to efficiently infer potential MDIs. Initially, we randomly mask portions of the input microbe-disease graph based on Bernoulli distribution to boost self-supervised training and minimize noise-related performance degradation. Secondly, we employ decoupled representation learning technology, compelling the graph neural network (GNN) to independently learn the weights for each feature subspace, thus enhancing its expressive power. Finally, we implement multi-scale information fusion technology to amalgamate the multi-layer outputs of GNN, reducing information loss due to occlusion. Extensive experiments on public datasets demonstrate that our model significantly surpasses existing top MDI prediction models. This indicates that our model can accurately predict unknown MDIs and is likely to aid in disease discovery and precision pharmaceutical research.

Objective:To evaluate the optimization efficacy of transversus thoracic muscle plane block (TTPB)-pectoral nerve block (PECS) with compound lidocaine-general anesthesia for modified radical mastectomy for breast cancer.Methods:Ninety female patients, aged 40-64 yr, with American Society of Anesthesiologists physical status Ⅰ or Ⅱ and body mass index <30 kg/m 2, undergoing elective modified radical mastectomy for breast cancer, were divided into 3 groups ( n=30 each) using the random number table method: general anesthesia group (group C), TTPB-PECS with compound lidocaine-general anesthesia group (group L), and TTPB-PECS with ropivacaine-general anesthesia group (group R). The laryngeal mask was used for total intravenous anesthesia.PECS I, PECS II and TTPB were performed sequentially after laryngeal mask placement in L and R groups, and 0.4% compound lidocaine 15, 15 and 10 ml (group L) and 0.375% ropivacaine 15, 15 and 10 ml (group R) were injected at the above three points, respectively.Patient-controlled intravenous analgesia (PCIA) was performed with sufentanil at patient-controlled analgesia (PCA) dose of 2 ml/dose and a lockout time of 15 min at the end of operation, and when visual analog scale (VAS) score ≥ 3 points, sufentanil 5 μg was given intravenously for rescue analgesia.The intraoperative consumption of propofol and remifentanil, emergence time, and laryngeal mask removal time were recorded.The Ramsay sedation score and duration of postoperative analgesia were recorded at 10 min after removal of the laryngeal mask.The consumption of sufentanil, ratio of the effective pressing times to the total pressing times of PCA (D 1/D 2 ratio), requirement for rescue analgesia, and occurrence of adverse effects such as nausea and vomiting, skin pruritus, bradycardia, and respiratory depression within 48 h after surgery were recorded. Results:Compared with C group, the intraoperative consumption of propofol and remifentanil was significantly reduced, the emergence time and laryngeal mask removal time were shortened, Ramsay sedation scores was decreased, postoperative VAS scores were decreased, duration of postoperative analgesia was prolonged, D 1/D 2 ratios were increased, the consumption of sufentanil was reduced, and the requirement for rescue analgesia and incidence of postoperative nausea and vomiting were decreased in R and L groups ( P<0.05). Compared with R group, the duration of postoperative analgesia was significantly prolonged, D 1/D 2 ratio was increased, the consumption of sufentanil was decreased, and the requirement for rescue analgesia was decreased in L group ( P<0.05). Conclusions:Compared with general anesthesia, TTPB-PECS with compound lidocaine-general anesthesia used in modified radical mastectomy for breast cancer is helpful in achieving a low-opioid anesthetic mode, which is more conducive to suppressing postoperative hyperalgesia and promoting early postoperative recovery, and the optimization efficacy is more significant than that of ropivacaine.

Objective:To evaluate the dose-effect relationship of compound lidocaine hydrochloride for transverse abdominal plane-rectus abdominis sheath block (TAP-RSB) for postoperative analgesia in elderly patients undergoing laparoscopic radical colon cancer surgery with general anesthesia.Methods:Elderly patients of either sex, aged≥65 yr, with body mass index <30 kg/m 2, of American Society Anesthesiologists physical status Ⅰ-Ⅲ, undergoing elective laparoscopic radical colon cancer surgery with general anesthesia, were selected.After induction of general anesthesia, compound lidocaine hydrochloride was given under ultrasound guidance for bilateral TAP block (20 ml on each side) and for bilateral RSB (10 ml on each side), with the initial concentration of 0.4%.Each time the concentration increased/decreased in the next patient depending on whether or not the analgesia was effective.The ratio between the two successive concentrations was 1.00∶1.15.The analgesic effects were evaluated by the Numerical Rating Scale at 1 h intervals from the time of postoperative admission to the post-anesthesia care unit until 8 h after TAP-RSB (Numerical Rating Scale ≤ 3 was considered as effective analgesia). The probit method was used to calculate the half effective concentration (EC 50) and 95% effective concentration (EC 95) and 95% confidence interval of compound lidocaine hydrochloride. Results:The EC 50 and EC 95(95% confidence interval)of compound lidocaine hydrochloride for TAP-RSB were 0.289% (0.232%-0.352%) and 0.404% (0.345%-0.970%), respectively, when used for postoperative analgesia in elderly patients undergoing laparoscopic radical colon cancer surgery with general anesthesia. Conclusions:The EC 50 and EC 95 of compound lidocaine hydrochloride for TAP-RSB are 0.289% and 0.404%, respectively, when used for postoperative analgesia in elderly patients undergoing laparoscopic radical colon cancer surgery with general anesthesia.

Objective:To explore the clinical characteristics and risk factors of the severe delayed encephalopathy after acute carbon monoxide poisoning (s-DEACMP).Methods:A retrospective analysis of 170 acute carbon monoxide poisoning (ACMP) patients treated in the Hyperbaric Oxygen (HBO) Department of Beijing Chao-yang Hospital, Capital Medical University from January 1st, 2017 to December 31st, 2020 was conducted. According to the occurrence of delayed encephalopathy, the ACMP patients were divided into DEACMP group and non-DEACMP (n-DEACMP) group. The DEACMP patients were stratified by the activities of daily living scale when they were most severely ill. The patients with total score≤60 were classified as s-DEACMP and the patients with total score >60 were classified as mild to moderate DEACMP (m-DEACMP). Their clinical characteristics were compared and the risk factors of s-DEACMP were analyzed.Results:There were 70 s-DEACMP patients, 49 m-DEACMP patients, and 51 n-DEACMP patients. Compared with the n-DEACMP group, the s-DEACMP group was older (average age: 59.0 vs. 49.0, P=0.005), had a higher proportion of patients over 40 years old (97.1% vs. 66.7%, P<0.001), lower Glasgow coma scale scores [(4.0±3.0) vs.(6.0±5.0), P=0.024] on admission to the hospital, longer consciousness disturbance [(32.0±31.8) h vs.(20.5±26.4) h, P=0.017], a higher proportion of patients with consciousness disturbance over 48 hours (24.3% vs. 9.8%, P=0.041), a lower proportion of patients receiving HBO therapy (70.0% vs. 86.3%, P=0.036), a higher proportion of patients with hypertension (38.6% vs. 17.6%, P=0.013), a higher proportion of patients with hyperhomocysteinemia (40.0% vs. 19.6%, P=0.017), and a higher proportion of patients with smoking index over 400 (24.3% vs. 9.8%, P=0.041). Compared with the m-DEACMP group, the s-DEACMP group had a higher proportion of patients with hyperhomocysteinemia (40.0% vs. 20.4%, P=0.024). Multivariate Logistic regression showed that age over 40 years old, consciousness disturbance over 48 hours, hypertension, and hyperhomocysteinemia were independent risk factors of s-DEACMP( P<0.05). Conclusion:The clinical characteristics of s-DEACMP patients are that the patients are older, have a deeper and longer consciousness disturbance, a lower proportion of early HBO intervention, a higher proportion of hypertension, hyperhomocysteinemia, and smoking index over 400. Among them, the age over 40 years old, disturbance consciousness over 48 hours, and hypertension were the independent risk factors of the occurrence of s-DEACMP.In additon hyperhomocysteinemia was also an idependent risk factor for s-DEAMP, which special worth attention.
