OBJECTIVE: To explore the efficacy and apoptosis of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of acute myeloid leukemia (AML) with ASXL1 mutation. METHODS: The clinical data of 80 AML patients with ASXL1 mutation treated in our hospital from January 2019 to December 2021 were retrospectively analyzed. The clinical characteristics of the patients were summarized, and the therapeutic effect and prognostic factors of allo-HSCT for the patients were analyzed. RESULTS: Among the 80 patients, 38 were males and 42 were females, and the median age was 39(14-65) years. There were 17 patients in low-risk group, 25 patients in medium-risk group and 38 patients in high-risk group. ASXL1 mutation co-occurred with many other gene mutations, and the frequent mutated genes were TET2 (71.25%), NRAS (18.75%), DNMT3A (16.25%), NPM1 (15.00%), CEBPA (13.75%). Among medium and high-risk patients, 29 underwent allo-HSCT, while 34 received chemotherapy. The 2-year overall survival (OS) rate and disease-free survival (DFS) rate of the allo-HSCT group were 72.4% and 70.2%, while those of the chemotherapy group were 44.1% and 34.0%, respectively. The statistical analysis showed significant differences between the two groups (both P < 0.01). Multivariate analysis showed that age at transplantation >50- years and occurrence of acute graft-versus-host disease after transplantation were poor prognostic factors for OS and DFS in transplantation patients. CONCLUSION Allo-HSCT can improve the prognosis of AML patients with ASXL1 mutation.

BACKGROUND: Blood glucose and serum albumin have been associated with cardiovascular disease prognosis, but the impact of admission-blood-glucose-to-albumin ratio (AAR) on adverse outcomes in critical ill coronary artery disease (CAD) patients was not investigated. METHODS: Patients diagnosed with CAD were non-consecutively selected from the MIMIC-IV database and categorized into quartiles based on their AAR. The primary outcome was 1-year mortality, and secondary endpoints were in-hospital mortality, acute kidney injury (AKI), and renal replacement therapy (RRT). A restricted cubic splines model and Cox proportional hazard models assessed the association between AAR and adverse outcomes in CAD patients. Kaplan-Meier survival analysis determined differences in endpoints across subgroups. RESULTS: A total of 8360 patients were included. There were 726 patients (8.7%) died in the hospital and 1944 patients (23%) died at 1 year. The incidence of AKI and RRT was 63% and 4.3%, respectively. High AAR was markedly associated with in-hospital mortality (HR = 1.587, P = 0.003), 1-year mortality (HR = 1.502, P < 0.001), AKI incidence (HR = 1.579, P < 0.001), and RRT (HR = 1.640, P < 0.016) in CAD patients in the completely adjusted Cox proportional hazard model. Kaplan-Meier survival analysis noted substantial differences in all endpoints based on AAR quartiles. Stratified analysis and interaction test demonstrated stable correlations between AAR and outcomes. CONCLUSIONS The results highlight that AAR may be a potential indicator for assessing in-hospital mortality, 1-year mortality, and adverse renal prognosis in critical CAD patients.

Objective:To compare the efficacy of body posture combined with pharmacotherapy and pharmacotherapy alone in the treatment of chronic subdural hematoma(CSDH).Methods:Firstly, retrospective case series study was conducted. Thirty cases of CSDH that had received body posture combined with pharmacotherapy at Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University from December 2016 to October 2020 were studied retrospectively. Twenty-seven patients were male, and 3 patients were female. The age of patients ( M(IQR)) was 66(16) years (range:28 to 84). Nineteen patients had unilateral hematoma, and 11 patients had bilateral hematoma. All patients received pharmacotherapy and body posture therapy that was to raise their lower limbs 20 to 30 cm with leg lift pad and get abdominal compressed with customized abdominal belt in supine position. Patients were required to maintain the body posture as much as possible, with the maximum to 16 to 18 hours per day. Patients with unilateral hematoma should tilt the head to the affected side and avoid tilting it to the opposite side. For patients with bilateral hematoma, there was no need for head lateralization. Patient were treated with oral dexamethasone and atorvastatin simultaneously. The preliminary efficacy of body posture combined with pharmacotherapy was determined by hematoma improvement rate which was analyzed by Clopper-Pearson method. Then, the multi-center, prospective, randomized controlled trial had carried out in 9 medical centers from August 2020 to November 2021. The stratified block randomization method was adopted. Patients were randomized in a ratio of 1∶1 to either receive pharmacotherapy alone(the control group) or body posture combined with pharmacotherapy(the experiment group) for 3 months and followed up for 6 months. Effective treatment was defined as complete absorption of hematoma, or the hematoma volume decreased by more than 10 ml and Markwalder grading scale score had improved by more than 1 point compared to the baseline. The efficacy rate and surgery conversion rate at 3 months and recurrence at 6 months were observed. Comparison between groups was performed with paired sample t test, Mann-Whitney U test, χ2 test, corrected χ2 test, or Fisher exact probability method. Logistic regression was used to compare the effective rate and operation rate between the two groups. Results:In the respective study, 30 patients completed follow-up 13 to 353 days after treatment. At the last follow-up, the incidence of almost complete absorption or significantly absorption of hematoma (hematoma volume was significantly reduced accompanied by symptom improvement) was 93.3%. The 95% CI for the incidence that analyzed by the Clopper-Pearson method was 77.9% to 99.2%. One hundred and six patients were enrolled in the multicenter study. Fifty-five patients underwent body posture combined with pharmacotherapy. The age was 74(17) years (range:26 to 92). Thirty-nine patients were males and 16 were females. Fifty-one patients underwent pharmacotherapy alone. The age was 69(12) years (range:48 to 84). Thirty-seven patients were males and 14 were females. The length of body posture recorded in diary card was (15.7±2.3) hours(range:7.6 to 19.3 hours). The efficacy rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 83.6% (46/55) and 56.9% (29/51), respectively at 3 months. The result of the logistic regression analysis showed that the efficacy of body posture combined with pharmacotherapy group was better than that of pharmacotherapy alone group ( OR=3.88,95% CI:1.57 to 9.58, P=0.003). Surgery rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 5.5% (3/55) and 21.6% (11/51) respectively. The result of Logistic regression showed that the pharmacotherapy alone group was more likely to be converted to surgery ( OR=0.21,95% CI:0.05 to 0.80, P=0.023). At the 6 months, no recurrence of cases was found in the body posture combined with pharmacotherapy group. However, the recurrence rate of pharmacotherapy alone group was 6.3% (3/48), there was no significant difference between the two groups ( P>0.05). Conclusion:The effect of body posture combined with pharmacotherapy for chronic subdural hematoma is better than that of pharmacotherapy alone.

Objective:To evaluate the effect of robot-assisted laparoscopic technology via abdominal approach for patients with primary retroperitoneal tumors.Methods:A retrospective cohort analysis was conducted for the clinical data of 71 patients who underwent robot-assisted laparoscopic resection of primary retroperitoneal tumor via abdominal approach at the Department of Urology of Sir Run Run Shaw Hospital,Zhejiang University School of Medicine from January 2015 to December 2023. There were 35 male and 36 female patients. The age ( M(IQR)) was 56(21) years (range: 21 to 83 years). The median tumor diameter was 46 (31) mm (range: 15 to 134 mm). Postoperative pathology revealed 58 benign and 13 malignant cases. Patients were divided into non-adherent group ( n=47) and adherent group ( n=24) based on whether the tumor was adhered to major organs or vessels. Perioperative and postoperative situation were compared between the two groups. Data comparisons were conducted using independent samples t-test for normally distributed continuous variables, Mann-Whitney U tests for non-normally distributed data, χ2 test or Fisher′s exact test for categorical variables. Kaplan-Meier survival analysis was employed to estimate 3-year recurrence or metastasis rate and 3-year mortality rate. Results:Operative time was 120(60) minutes (range: 45 to 440 minutes), intraoperative blood loss was 50 (80) ml (range: 10 to 2 000 ml). The median change of intraoperative mean arterial pressure was 40 (19) mmHg(1 mmHg=0.133 kPa)(range: 10 to 112 mmHg). Intraoperative blood transfusion was required in 7 cases, whereas 64 cases did not necessitate transfusion. The change in hemoglobin levels before and after surgery was (17.9±13.6) g/L (range:-16 to 53 g/L), and the median change in serum creatinine levels was 2.0 (14.5) μmol/L (range:-71.0 to 100.4 μmol/L). Postoperative fasting duration was 2.0 (1.5) days (range: 1 to 6 days), and the median hospital stay was 10.0 (7.5) days (range: 4 to 24 days). No perioperative mortality occurred in any of the patients. The non-adherent group had shorter operation time, less estimated blood loss, lower blood transfusion rate, smaller delta value of hemoglobin before and after surgery, larger delta value of creatinine before and after surgery, fewer postoperative complications, shorter postoperative fasting time, and shorter length of hospital stay than the adherent group(all P<0.05), while there was no significant difference in mean arterial pressure fluctuation between the two groups ( P>0.05). Follow-up data were available for 69 patients, with a median follow-up duration of 39 (43) months (range: 4 to 88 months). Among these patients, 40 completed the 3-year follow-up. The 3-year recurrence or metastasis rate was 10.14%, and the 3-year mortality rate was 2.90%. Conclusions:Robot-assisted laparoscopic technology via abdominal approach for resection of primary retroperitoneal tumors is safe and feasible. It can also achieve secure surgical outcome for primary retroperitoneal tumors adherent to surrounding organs or vessels, albeit with increased surgical complexity and slower postoperative recovery compared to non-adherent cases.

BACKGROUND: The purpose of this study was to evaluate the safety and efficacy of subsequent radiotherapy (RT) following first-line treatment with durvalumab plus chemotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC). METHODS: A total of 122 patients with ES-SCLC from three hospitals during July 2019 to December 2021 were retrospectively analyzed. Inverse probability of treatment weighting (IPTW) analysis was performed to address potential confounding factors. The primary focus of our evaluation was to assess the impact of RT on progression-free survival (PFS) and overall survival (OS). RESULTS: After IPTW analysis, 49 patients received durvalumab plus platinum-etoposide (EP) chemotherapy followed by RT (Durva + EP + RT) and 72 patients received immunochemotherapy (Durva + EP). The median OS was 17.2 months vs . 12.3 months (hazard ratio [HR]: 0.38, 95% confidence interval [CI]: 0.17-0.85, P = 0.020), and the median PFS was 8.9 months vs . 5.9 months (HR: 0.56, 95% CI: 0.32-0.97, P = 0.030) in Durva + EP + RT and Durva + EP groups, respectively. Thoracic radiation therapy (TRT) resulted in longer OS (17.2 months vs . 14.7 months) and PFS (9.1 months vs . 7.2 months) compared to RT directed to other metastatic sites. Among patients with oligo-metastasis, RT also showed significant benefits, with a median OS of 17.4 months vs . 13.7 months and median PFS of 9.8 months vs . 5.9 months compared to no RT. Continuous durvalumab treatment beyond progression (TBP) prolonged OS compared to patients without TBP, in both the Durva + EP + RT (NA vs . 15.8 months, HR: 0.48, 95% CI: 0.14-1.63, P = 0.238) and Durva + EP groups (12.3 months vs . 4.3 months, HR: 0.29, 95% CI: 0.10-0.81, P = 0.018). Grade 3 or 4 adverse events occurred in 13 (26.5%) and 13 (18.1%) patients, respectively, in the two groups; pneumonitis was mostly low-grade. CONCLUSION Addition of RT after first-line immunochemotherapy significantly improved survival outcomes with manageable toxicity in ES-SCLC.

Objective:To develop and validate a clinical prediction model for assessing the risk of postoperative pulmonary complications (PPCs) in elderly patients undergoing surgery with general anesthesia.Methods:This prospective observational study enrolled patients aged ≥65 years who underwent general anesthesia with mechanical ventilation duration >3 hours across six tertiary hospitals between December 2022 and August 2023. Based on follow-up outcomes (until discharge or postoperative day 7), patients were categorized into a non-PPCs group and a PPCs group. Detailed records included baseline patient characteristics, preoperative comorbidities, surgical information (type, duration), and bedside lung ultrasound scores (LUS) assessed within 24 hours postoperatively using a standardized 12-zone protocol. Predictor selection was performed using LASSO regression. Significant predictors identified were incorporated into a multivariate logistic regression analysis to build the prediction model, visualized as a nomogram. Internal validation was conducted via bootstrap resampling (1 000 repetitions). Model performance was evaluated using the area under the receiver operating characteristic curve (AUC) for discrimination, calibration curves for calibration accuracy, and decision curve analysis (DCA) for clinical utility.Results:A total of 130 eligible elderly surgical patients were included. PPCs occurred in 17 patients (incidence rate: 13.1%). Multivariate analysis identified LUS ( OR=1.248, 95% CI: 1.099-1.417, P=0.001) and elective surgery type ( OR=0.206, 95% CI: 0.043-0.988, P=0.048) as independent predictors of PPCs. The nomogram model demonstrated an AUC of 0.867 (95% CI: 0.775-0.959) upon initial testing. Internal validation confirmed good discrimination (AUC=0.863, 95% CI: 0.778-0.972). Calibration curves indicated excellent agreement between predicted probabilities and observed outcomes. Decision curve analysis demonstrated significant clinical net benefit across a wide range of threshold probabilities (0.03-0.89). Conclusions:The clinical prediction model, developed using early postoperative LUS scores and surgical type, effectively predicts the risk of postoperative pulmonary complications in elderly patients following surgery under general anesthesia. The model exhibits strong discrimination, calibration, and clinical utility, providing clinicians with a reliable tool for individualized risk assessment to support clinical decision-making and potentially reduce PPC incidence.

OBJECTIVE: To evaluate clinical effect of transcutaneous acupoint electrical stimlation (TEAS) on perioperative immune function and postoperative recovery in patients with total knee arthroplasty (TKA). METHODS: From November 2021 to July 2022, 80 patients with unilateral TKA were selected and divided into TEAS group and sham TEAS group according to different treatment methods. There were 40 patients in TEAS group, including 9 males and 31 females;aged from 61 to 79 years old with an average of (66.90±5.86) years old;body mass index (BMI) ranged from 19.53 to 30.47 kg·m^-2 with an average of (25.34±2.83) kg·m^-2;21 patients on the left side, 19 patients on the right side;according to American Society of Anesthesiologists (ASA), 30 patients with gradeⅡ, 10 patients with grade Ⅲ;TEAS were administered at the bilateral Hegu (LI4), Neiguan (PC6) and non-operative Zusanli (ST36) and Sanyinjiao (SP6) points from 30 min before anesthesia to the end of operation, the frequency was 2/10 Hz, current intensity was tolerable and/or muscle rhythmic twitches of limbs were performed. There were 40 patients in sham TEAS group, including 9 males and 31 females;aged from 60 to 80 years old with an average of (67.35±4.29) years old;27 patients on the left side and 13 patients on the right side;BMI ranged from 20.02 to 30.09 kg·m^-2 with an average of (25.02±2.23) kg·m^-2;28 patients with gradeⅡand 12 patients with grade Ⅲ according to ASA;Electrodes were attached to the same points without electrical stimulation. Percentage contents of 24 h CD3+, CD4+, CD8+ and NK cells, postoperative infection, incidence of nausea, vomiting, abdominal distension and pruritus within 48 h after surgery, the first time on the ground, length of hospital stay and quality of recovery-15 (QoR-15) score were compared between two groups. RESULTS: Compared with pseudoteas group, expressions of CD3+ and CD4+ T lymphocytes in TEAS group were significantly increased at 24 h after surgery (P<0.05). The incidence of nausea within 48 h after surgery and the time spent on the ground early after surgery were significantly decreased (P<0.05). There was no significant difference in postoperative secondary infection, adverse reactions such as vomiting, abdominal distension, pruritus and hospitalization days (P>0.05). CONCLUSION Percutaneous acupoint electrical stimulation could improve perioperative cellular immunity in patients with total knee replacement, alleviate immunosuppression, reduce incidence of postoperative adverse reactions, and promote early postoperative recovery.
