Emergence agitation （EA） is a common complication after general anesthesia， especially in children and adolescents. Remifentanil， as a short-acting μ-receptor agonist， has become an important drug for the prevention and treatment of EA due to its rapid recovery and low risk of respiratory depression. This article reviews the mechanism of action and clinical research progress of remifentanil in the prevention and treatment of EA. Its mechanism of action involves the inhibition of pain signals mediated by traditional μ-receptor activation and potential new mechanism based on neural-endocrine-immune network， including regulation of microglial inflammatory pathways， and the modulation of cytokines and chemokines，etc. Clinical studies have shown that remifentanil can significantly shorten the recovery time， reduce the incidence of EA， and further optimize the analgesic effect and recovery quality by combining with other drugs （such as local anesthetics， sedatives， and opioid drugs）. Future research should further explore the mechanism of action of remifentanil， optimize clinical treatment strategies， and conduct large- scale clinical trials to standardize the drug use plan， while paying attention to its long-term effects and the development of multimodal treatment plans to promote the further development of EA prevention and treatment plans.

Objective To investigate the risk factors for arrhythmia after robotic cardiac surgery. Methods The data of the patients who underwent robotic cardiac surgery under cardiopulmonary bypass (CPB) from July 2016 to June 2022 in Daping Hospital of Army Medical University were retrospectively analyzed. According to whether arrhythmia occurred after operation, the patients were divided into an arrhythmia group and a non-arrhythmia group. Univariate analysis and multivariate logistic analysis were used to screen the risk factors for arrhythmia after robotic cardiac surgery. Results A total of 146 patients were enrolled, including 55 males and 91 females, with an average age of 43.03±13.11 years. There were 23 patients in the arrhythmia group and 123 patients in the non-arrhythmia group. One (0.49%) patient died in the hospital. Univariate analysis suggested that age, body weight, body mass index (BMI), diabetes, New York Heart Association (NYHA) classification, left atrial anteroposterior diameter, left ventricular anteroposterior diameter, right ventricular anteroposterior diameter, total bilirubin, direct bilirubin, uric acid, red blood cell width, operation time, CPB time, aortic cross-clamping time, and operation type were associated with postoperative arrhythmia (P<0.05). Multivariate binary logistic regression analysis suggested that direct bilirubin (OR=1.334, 95%CI 1.003-1.774, P=0.048) and aortic cross-clamping time (OR=1.018, 95%CI 1.005-1.031, P=0.008) were independent risk factors for arrhythmia after robotic cardiac surgery. In the arrhythmia group, postoperative tracheal intubation time (P<0.001), intensive care unit stay (P<0.001) and postoperative hospital stay (P<0.001) were significantly prolonged, and postoperative high-dose blood transfusion events were significantly increased (P=0.002). Conclusion Preoperative direct bilirubin level and aortic cross-clamping time are independent risk factors for arrhythmia after robotic cardiac surgery. Postoperative tracheal intubation time, intensive care unit stay, and postoperative hospital stay are significantly prolonged in patients with postoperative arrhythmia, and postoperative high-dose blood transfusion events are significantly increased.

In the past few decades, the global obesity population has been increasing, and still has an upward trend. With obesity, the risk of cardiovascular and cerebrovascular diseases has increased. It’s found that an increase in body mass index is associated with the occurrence of some cardiovascular and cerebrovascular diseases Hypertension and hyperlipidemia, as common chronic cardiovascular diseases, are particularly affected by obesity, which has attracted extensive attention in recent years. Moreover, the occurrence of hypertension and hyperlipidemia under the influence of obesity is significantly related, and their synergy can also cause a variety of cardiovascular and cerebrovascular diseases. However, there is still less work to study these three factors at the same time. Therefore, on the basis of summarizing the molecular mechanisms of obesity affecting hypertension and hyperlipidemia, this paper summarizes the relevant molecular mechanisms of hypertension and hyperlipidemia under the influence of obesity, and points out the co-acting molecules, providing a reference for future research on cardiovascular and cerebrovascular diseases.

Objective:To analyze the efficacy of allo-HSCT with total body irradiation (TBI) and chemotherapy alone in the treatment of adult ALL and to explore the factors affecting prognosis.Methods:The clinical data of 95 adult patients with ALL who underwent allo-HSCT from January 2015 to August 2022 were included. According to the conditioning regimen, the patients were divided into two groups: the TBI plus cyclophosphamide (TBI/Cy) group ( n=53) and the busulfan plus cyclophosphamide (Bu/Cy) group ( n=42). Hematopoietic reconstitution after transplantation, GVHD, transplantation-related complications, relapse rate (RR), non-relapse mortality (NRM), OS, and LFS were compared, and the factors related to prognosis were analyzed. Results:The median time of neutrophil engraftment was 14 (10-25) days in the TBI/Cy group and 14 (10-24) days in the Bu/Cy group ( P=0.106). The median time of megakaryocyte engraftment was 17 (10-42) days in the TBI/Cy group and 19 (11-42) days in the Bu/Cy group ( P=0.488). The incidence of grade Ⅱ-Ⅳ acute GVHD (aGVHD) in the TBI/Cy and Bu/Cy groups was 41.5% and 35.7%, respectively ( P=0.565). The incidence of grade Ⅲ-Ⅳ aGVHD in these two groups was 24.5% and 4.8%, respectively ( P=0.009). The incidence of severe chronic GVHD in the two groups was 16.7% and 13.5%, respectively ( P=0.689). The incidence of cytomegalovirus infection, Epstein-Barr virus infection, severe infection, and hemorrhagic cystitis in the two groups was 41.5% and 35.7% ( P=0.565), 34.0% and 35.7% ( P=0.859), 43.4% and 33.3% ( P=0.318), and 20.8% and 50.0% ( P=0.003), respectively. The median follow-up time was 37.1 months and 53.3 months in the TBI/Cy and Bu/Cy groups, respectively. The 2-year cumulative RR was 17.0% in the TBI/Cy group and 42.9% in the Bu/Cy group ( P=0.017). The 2-year cumulative NRM was 24.5% and 7.1%, respectively ( P=0.120). The 2-year LFS was 58.5% and 50.0%, respectively ( P=0.466). The 2-year OS rate was 69.8% and 64.3%, respectively ( P=0.697). In the multivariate analysis, the conditioning regimen containing TBI was a protective factor for relapse after transplantation ( HR=0.304, 95% CI 0.135-0.688, P=0.004), whereas the effect on NRM was not significant ( HR=1.393, 95% CI 0.355-5.462, P=0.634). Infection was an independent risk factor for OS after allo-HSCT in adult patients with ALL. Conclusion:allo-HSCT based on TBI conditioning regimen had lower relapse rate and lower incidence of hemorrhagic cystitis for adult ALL, compared with chemotherapy regimen. While the incidence o grade Ⅲ/Ⅳ aGVHD was hgher in TBI conditioning regimen than that in chemotherapy regimen.

Case 1: A 27-year-old female with ALK-positive anaplastic large cell lymphoma/leukemia; Case 2: A 27-year-old male with acute myeloid leukemia; Case 3: A 56-year-old male with myelodysplastic syndrome. These three patients underwent haploid hematopoietic stem cell transplantation and experienced severe oral mucosal inflammation, nausea, vomiting, diarrhea, and other symptoms over a long period, which significantly restricted eating. Neurological and psychiatric symptoms appeared at 50, 38, and 50 days following transplantation, respectively. The diagnosis of Wernicke encephalopathy was made by head magnetic resonance imaging, whereas the condition improved significantly after intravenous infusion of vitamin B 1.

Nerve block is a technique for anesthesia and pain management, which is realized by blocking nerve conduction in a specific nerve area with local anesthetic drugs. Compared with general anesthesia, nerve block has many advantages, which can provide local and selective analgesic effect, and meanwhile reduce complications and drug side effects related to general anesthesia. Dexmedetomidine is a type of α₂ adrenergic receptor agonist, and as a potential adjuvant, dexmedetomidine has been widely applied in nerve block. Dexmedetomidine has sedative, analgesic and anti-anxiety effects, and can be used in combination with local anesthetics to enhance the effect of nerve block. In this paper, the clinical effects of dexmedetomidine as an adjuvant of nerve block in various parts are reviewed, and application in maxillofacial nerve block and stellate ganglion block was added in order to provide reference for nerve block anesthesia and analgesia.

Objective:To explore the TCM syndromes and risk factors of patients with anxiety and/or depression after coronary revascularization through real-world data mining based on the national pilot project of Chinese and Western medicine clinical collaboration for major difficult diseases; To provide clinical evidence and guide practice for the diagnosis and treatment of bicardiac diseases after coronary revascularization.Methods:A retrospective multi-center clinical study was conducted. From September 2018 to December 2019, 577 patients who underwent successful percutaneous coronary intervention in the Department of Cardiovascular Medicine of Affiliated Hospital of Liaoning University of Traditional Chinese Medicine, Department of Cardiovascular Medicine of the People's Hospital of Liaoning Province were enrolled using the collaborative platform system of TCM and Western Medicine Diagnosis and follow-up for coronary disease. Clinical data database was established. Baseline data, TCM syndrome types and elements, coronary angiography and stent implantation status, relevant disease history, Hamilton Anxiety and Depression Scale, etc. were collected. A combination of postoperative phone calls and outpatient visits was performed, with follow-up every 3 months for a total of 1 year. The TCM treatment patterns and risk factors of patients with anxiety and depression after coronary artery revascularization surgery were analyzed and explored.Results:A total of 577 patients were enrolled and 561 patients were followed up. Age distribution: The age of males and females undergoing coronary revascularization due to ACS was (61.80±11.00) years and (68.37±10.13) years, with no statistical significance between groups ( P>0.05), but the age of onset in males tended to be earlier than in females. The distribution pattern of TCM syndrome elements showed that the most deficiency syndrome elements were qi deficiency (61.75%, 176/285), followed by yin deficiency (28.77%, 82/285). The most common excessive symptom was blood stasis (39.13%, 108/276), and the other syndromes were phlegm turbidity (36.23%, 100/276) and qi depression (20.29%, 56/276), etc. The distribution of TCM syndrome types was as follows: in the population with anxiety and depression state of coronary revascularization, the TCM syndrome types with frequency higher than 10% were successively phlegm and blood stasis with depression syndrome, qi deficiency and blood stasis syndrome, heart, gallbladder and qi deficiency and qi-yin deficiency with blood stasis syndrome. Among the people without anxiety and depression, the TCM syndromes with a frequency higher than 10% were heart blood stasis syndrome and qi deficiency and blood stasis syndrome, with statistical significance ( χ2=12.07, P<0.01). Correlation analysis showed that the number of stents, and LDL-C were positive correlated with anxiety and depression( r values were 0.107, 0.118,respectively, P<0.05), and the uric acid was negative correlation ( r=-0.127, P=0.011). Multivariate Cox proportional hazards regression showed the age [ RR (95% CI)=1.052 (1.012-1.094), P=0.010] and diabetes mellitus [ RR (95% CI)=4.561 (1.028-20.238), P=0.046] at the sixth month of treatment. Conclusions:The age of acute coronary syndrome and coronary revascularization is mainly concentrated in patients aged 60-70 years, and male patients tend to have earlier onset than female patients, and the risk of coronary heart disease is relatively high. Qi-deficiency syndrome accounts for the highest proportion, and the most excessive syndrome is blood stasis syndrome. The TCM syndromes with high frequency of anxiety and depression are phlegm and blood stasis with depression syndrome and qi-yin deficiency with blood stasis syndrome. The number of stents implanted and low density lipoprotein cholesterol are positively correlated with postoperative anxiety and depression. Age and diabetes history are independent risk factors for end-point events at about 6 months after treatment.

Objective:To evaluate the safety and efficacy of bortezomib plus highdose melphalan (L-phenylalanine nitrogen mustard) (Bor-HDM) pretreatment regimen for multiple myeloma (MM) with autologous hematopoietic stem cell transplantation (ASCT).Methods:From August 2008 to December 2021, the relevant clinical data were retrospectively reviewed for 58 MM patients undergoing MM transplantation.The conditioning regimens were Bor-HDM (n=36) and HDM (n=22). Non-hematopoietic adverse reactions, hematopoietic reconstruction time, remission rate post-ASCT and minimal negative rate of residual disease (MRD) on flow cytometry within 3 months post-ASCT and survivals were analyzed.Results:In Bor-HDM and HDM groups, median time of neutrophil engraftment was 12(8-30) and 11(8-29) day and median time of platelet reconstitution 16(8-33) and 16(7-32) day respectively.There was no significant inter-group difference ( P=0.890, P=0.638). In Bor-HDM group, the most common non-hematological adverse reactions were nausea (n=21, 58.0%) and diarrhea (n=11, 30.6%). There was no transplant-related death.Complete remission (CR) rate was (25/36, 69.4%) versus (9/22, 40.9%). The inter-group difference was statistically significant ( P=0.032). Median follow-up period was 29.0(2.0-91.0) vs. 20.5(5.0-114.0) month, 3-year progression-free survival(PFS)62.1% vs. 39.7% and 3-year overall survival(OS) 83.8% vs. 62.5%.There were relapse (n=10 vs.10) and death (n=6 vs. 7). Median PFS in Bor-HDM and HDM groups was non-attained and 27 months( P=0.047) and median OS time non-attained and 40 months respectively ( P=0.282). Multivariate analysis revealed that CR was an independent risk factor for PFS ( HR=28.896, 95% CI: 6.130-136.198, P<0.001). Non-CR was an independent risk factor for OS ( HR=3.843, 95% CI: 1.334-11.071, P=0.013; HR=28.595, 95% CI: 6.273-130.355, P<0.001). Conclusions:Bor-HDM pretreatment regimen of ASCT is both safe and efficacious for MM patients.
