Objective:To evaluate the efficacy and safety of lenvatinib combined with camrelizumab as the second-line treatment for advanced intrahepatic cholangiocarcinoma (ICC).Methods:The clinical data of patients with advanced ICC undergoing the second-line treatment of lenvatinib combined with camrelizumab in the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University from June 2021 to June 2022 were screened and analyzed. A total of 12 patients were enrolled, including seven males and five females, aged (67.5±8.6) years. Response evaluation criteria in solid tumor 1.1 was used to evaluate the efficacy of treatment. The safety assessment adopts the Adverse Event Evaluation Standard 5.0. Kaplan-Meier method was conducted to plot survival curves.Results:Among the 12 patients (after 1-7 cycles of immune and targeted therapy), three achieved partial response, four achieved stable disease, and five were defined as progression disease. Adverse events of different degrees occurred in seven cases, among which three patients had adverse events of grade ≥ 3: one with hypertension, which was managed after antihypertensive and symptomatic treatment; one with elevated serum total bilirubin, which was improved after reducing the dose of lenvatinib; one with liver dysfunction, which was considered as immune-related liver toxicity and alleviated after discontinuing camrelizumab. The 1-month, 3-month, and 6-month survival rates and progression-free survival rates of the patients were 100.0%, 91.7%, 66.7%, and 83.3%, 41.7%, and 25.0%, respectively. The median overall survival of patients was 14.7 months (95% CI: 9.2-21.2) and the median time to progression was 8.0 months (95% CI: 4.1-11.9). Conclusion:Combination of lenvatinib and camrelizumab could bring survival benefits with controllable adverse events as the second-line treatment of patients with advanced ICC.

Objective:To investigate the safety and effectiveness of endoscopic retrograde cholangiopancreatography (ERCP) for the diagnosis and treatment of pediatric pancreaticobiliary maljunction (PBM).Methods:Data of 40 pediatric patients under 14 with PBM diagnosed and treated by ERCP at Department of Gastroenterology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from November 2012 to September 2022 were collected. PBM types, ERCP-related diagnosis and treatment, adverse events and prognosis were retrospectively analyzed.Results:Nineteen cases were P-B type (joining of common bile duct with pancreatic duct), 17 were B-P type (joining of pancreatic duct with common bile duct), and 4 were complex type. Forty children with PBM underwent 50 ERCP-related operations, among which 48 procedures succeeded. One case failed during cannulation of ERCP, replaced by rendezvous-assisted endoscopic retrograde pancreatography (RV-ERP) afterwards. There were no serious postoperative adverse events such as bleeding, perforation or death. Thirty-four patients (85%) were followed up successfully, among which 14 underwent further surgery and 20 continued conservative treatment.Conclusion:ERCP is the golden standard to diagnose pediatric PBM, and it is also safe and effective treatment for PBM.

Objective:To investigate the clinical characteristics and prognosis of patients with left ventricular assist device (LVAD) implantation during the perioperative period.Methods:This retrospective study included 14 patients with end-stage heart failure who underwent LVAD implantation in the department of intensive care medicine of Nanjing Hospital Affiliated to Nanjing Medical University from February 2022 to March 2023, including 12 males and 2 females patients, the mean age was (57.6±9.8)years old. All patients were implanted with Corheart 6 implantable left ventricular assist system, did not use other mechanical assisted circulatory devices. The clinical data of enrolled patients were collected, and the clinical characteristics and prognosis during ICU treatment were analyzed.Results:Dilated cardiomyopathy (DCM) was the most common primary cause of heart failure. The results of transthoracic echocardiography showed that the left ventricular ejection fraction (0.297±0.074 vs. 0.238±0.064, P=0.031) of patients was significantly increased, while the left ventricular end diastolic diameter[69.0(65.8, 74.3)mm vs. 76.5(72.8, 83.0)mm, P=0.003]and systolic end systolic diameter[61.5(53.7, 65.3)mm vs. 68.3(63.8, 71.9)mm, P=0.005]were significantly decreased post LVAD implantation as compared to before LVAD implantation. Within one week after implantation, there was no significant difference in LVAD rotational speed, flow rate, and pulsation index ( P>0.05). During ICU treatment, dobutamine (13 cases) was the most commonly used vasoactive agent. 9 patients used phosphodiesterase Ⅲ inhibitors for perioperative pulmonary hypertension. Targeted management of volume and pressure indicators was conducted for enrolled patients to prevent postoperative right heart failure and to reduce right heart burden. Within 72 hours after LVAD implantation, the average pulmonary artery pressure of patients was 24 (22, 26) mmHg to 26 (21, 28)mmHg (1 mmHg=0.133 kPa), while the fluid balance was(-581±778)ml to(-1 209±1 134)ml. All enrolled patients survived to 28 days after LVAD implantation. The length of stay in the ICU was (8.0±1.8) days and the total length of hospital stay was 33 (29, 41)days, while the time of mechanical ventilation was 8 (5, 28)h. Conclusion:LVAD implantation can help improve left ventricular systolic function, prolong survival time so as to serve as an important means of terminal treatment or bridging therapy for heart transplantation of patients with end-stage heart failure. To strengthen the perioperative hemodynamic regulation and maintain the cardiac function of patients with LVAD implantation is the important purposes of ICU postoperative management.

Traf2- and Nck-interacting kinase (TNIK) is closely related to the cancer occurrence, development, and prognosis. TNIK plays an important role in regulating Wnt/β-catenin pathway, thus becoming a potential target for cancer treatment. Various small-molecule TNIK inhibitors with diverse structures and potent in vitro activities have been developed to treat tumors. However, no TNIK inhibitor has entered clinical phase mainly due to poor selectivity, toxicity, and unsatisfied in vivo anti-tumor efficiency. This review summarizes the research progress of small molecule inhibitors targeting TNIK, with the aim of giving some guidance for future research and development of small-molecule inhibitors.

Postoperative pain seriously affects the recovery process of patients, resulting in prolonged hospital stay and increased care costs. Appropriate application of patient-controlled analgesia devices can effectively relieve perioperative acute pain. In 1994 patient-controlled analgesia began to be used in Peking Union Medical College Hospital, and the Acute Pain Service Working Group was established in 2004. With the cooperation of anesthesiologists and specialist nurses, the group jointly has implemented the whole process and standardized management based on patient-controlled analgesia, and constantly improved and innovated working methods, laying a solid foundation for the development of postoperative pain management. This paper systematically reviews and summarizes the work from the aspects of clinical focus, nursing management experience, promotion and dissemination of pain treatment concepts, and development of acute pain service model under the new situation, with the hope of providing valuable reference for comprehensively strengthening pain management in the process of diagnosis and treatment, and enhancing patients' satisfaction with perioperative analgesia services.

  Objective  To identify the risk factors for postoperative nausea and vomiting (PONV) in surgical patients undergoing patient controlled intravenous analgesia (PCIA).  Methods  Our study was a retrospective cohort study, including patients who underwent surgery at Peking Union Medical College Hospital from July 1 to October 31, 2023 and received PCIA after surgery. Patient characteristics, medical history, surgical information, intraoperative medication information, postoperative analgesia follow-up information were obtained through the electronic medical record system. The patients were divided into PCIA-PONV group and non-PCIA-PONV group, depending on the occurrence of PONV during PCIA, and all patients were also divided into PCIA-POV group and non-PCIA-POV according to whether postoperative vomiting (POV) occurred. Multivariate Logistic regression analysis was used to identify the risk factors for PCIA-PONV and PCIA-POV.  Results  A total of 1373 patients were included in this study, with 676 cases in PCIA-PONV group. The incidence of PCIA-PONV was 49.2%. There were 285 patients in PCIA-POV group, and the incidence of PCIA-POV was 20.8%. The results of multivariate Logistic regression analysis showed that female (OR=2.134, 95% CI: 1.590-2.865, P < 0.001) and abdominal surgery (OR=1.655, 95% CI: 1.253-2.186, P < 0.001) were risk factors for PCIA-PONV, whereas the increase of age (OR=0.990, 95% CI: 0.982-0.998, P=0.019) and the increase of BMI (OR=0.961, 95% CI: 0.932-0.991, P=0.012) were protective factors for PCIA-PONV. Female (OR=2.646, 95% CI: 1.754-3.992, P < 0.001), history of general anesthesia (OR=1.372, 95% CI: 1.042-1.806, P=0.024), and intraoperative use of high-dose opioids (OR=1.607, 95% CI: 1.206-2.142, P=0.001) were risk factors for PCIA-POV, whereas no intraoperative use of neuromuscular blocking antagonists (OR=0.393, 95% CI: 0.237-0.651, P < 0.001) was protective factor for PCIA-POV.  Conclusions  Our study reveals the risk factors for PONV in surgical patients undergoing PCIA, and shows that comprehensive preoperative assessment and reasonable perioperative management strategies are significant in the prevention of PCIA-PONV.

Postoperative pain, a common problem in perioperative management, has negative impact on patients' experience and functional recovery. The development of postoperative pain is not only related to direct surgical trauma, but also a series of preventable perioperative risk factors, among which perioperative sleep quality should not be neglected. In recent years, more and more researches have indicated that poor perioperative sleep quality is a risk factor for both acute and chronic postoperative pain, and some researches have even pointed out that sleep quality can directly influence patients' pain threshold. Therefore, this review aims to summarize current research progress on the influence of perioperative sleep quality on postoperative pain, hoping to provide reference for improving the perioperative pain management for patients.

The acupoint sensitization theory,a breakthrough in acupuncture and moxibustion over the past two decades,has greatly enhanced the understanding of meridians and acupoints while increasing the effectiveness of clinical diagnosis and treatment in acupuncture and moxibustion practices.The number of studies on surface sensitization site detection for different diseases is increasing.However,systematic sorting and a summary of the detection mode of surface sensitization points are lacking.Therefore,this study categorizes the method of surface sensitization point detection into two modes:pan-scanning and focused scanning.The classification is based on the characteristics of the openness of the research purpose,the precision of the target range,and the degree of variation during detection.The two modes have considerable differences in the exploration efficiency and the presentation of result.The pan-scanning mode can be further subdivided into holistic and localized pan-scanning modes,whereas the focused-scanning mode can be subdivided into fixed-and variable-focused scanning modes.This study analyzes the application scenarios,characteristics,advantages,and limitations of each detection mode and presents opinions on mode selection,mode innovation,and future development directions.This study aims to provide valuable insights and guidance for the follow-up research on surface sensitization site detection of various diseases.

Objective To investigate the efficacy and safety of tyrosine kinase inhibitor(TKI)combined with immune checkpoint inhibitor as the second-line therapy for advanced hepatocellular carcinoma(HCC).Methods A retrospective analysis was performed for the clinical data of 63 patients with advanced HCC who were admitted to Department of Interventional Radiology,The First Affiliated Hospital of Soochow University,from January 2018 to December 2022,and all patients experienced progression/intolerance after transcatheter arterial chemoembolization combined with first-line TKI and were switched to second-line TKI with or without immune checkpoint inhibitor.The 32 patients receiving second-line TKI with immune checkpoint inhibitor were enrolled as combination group,and the 31 patients receiving second-line TKI alone were enrolled as single treatment group.Modified Response Evaluation Criteria in Solid Tumors was used to evaluate tumor response,and Common Terminology Criteria for Adverse Events 5.0 was used to evaluate adverse events.The Kaplan-Meier method was used to calculate median overall survival(mOS)and median progression-free survival(mPFS)for the two groups,and the two groups were compared in terms of objective response rate(ORR)and disease control rate(DCR).The chi-square test was used for comparison of baseline data and follow-up results between groups.Results The median follow-up time was 16.5(3.2-53.4)months for the 63 patients.The combination group had an mOS of 24.3(95%confidence interval[CI]:20.0-28.6)months and an mPFS of 9.8(95%CI:7.5-12.1)months,while the single treatment group had an mOS of 15.8(95%CI:11.4-20.1)months and an mPFS of 4.1(95%CI:3.2-4.9)months,and there were significant differences in mOS and mPFS between the two groups(P=0.029 and 0.038).The combination group had an ORR of 47%and a DCR of 84%,while the single treatment group had an ORR of 19%and a DCR of 65%;there was a significant difference in ORR between the two groups(P=0.021),but with no significant difference in DCR between the two groups(P=0.070).As for adverse events,4 patients(12.5%)in the combination group and 3(10.0%)in the single treatment group experienced grade Ⅲ-Ⅳ serious adverse events,with no fatal drug reactions in either group,and there was no significant difference in the incidence rate of adverse events between the two groups(P=0.783).Conclusion Compared with TKI alone,TKI combined with immune checkpoint inhibitor has a more significant therapeutic effect as the second-line therapy for advanced HCC,without increasing serious adverse reactions.

Objective:To explore the effectiveness and safety of endoscopic ultrasound-guided pancreatic duct drainage (EUS-PD).Methods:A retrospective analysis was conducted on data of 16 patients who underwent EUS-PD because of endoscopic retrograde pancreatography (ERP) failure, poor effectiveness or anatomical changes and couldn't undergo the routine ERP in Nanjing Drum Tower Hospital from June 2018 to July 2022. The technical success of EUS-PD, clinical efficacy and post-procedure adverse events were analyzed.Results:In the 16 patients, there were 14 males and 2 females, with age of 50.69±12.95 years. A total of 19 times of EUS-PD operations were included, 3 of them were rendezvous-assisted endoscopic retrograde pancreatography (RV-ERP), 15 transgastric or transenteric EUS-guided stent placement and 1 was EUS-guided nasopancreatic duct placement. Technical success was achieved in 84.21% (16/19) patients, and among whom 93.75% (15/16) achieved clinical success. The overall incidence of postoperative adverse events was 52.63% (10/19) including 47.37% (9/19) abdominal pain, 15.79% (3/19) fever and 15.79% (3/19) postoperative pancreatitis. All adverse effects were relieved after general conservative treatment and no primary disease or surgery-related death occurred. The mean follow-up was 17.6 (8.2,22.3) months and 93.75% (15/16) of the patients were followed up. By the time of follow-up, 76.92% (10/13) of the patients who had successfully received EUS-PD had no recurrence of abdominal pain or distension.Conclusion:EUS-PD is a safe and effective alternative therapy for those with pancreatic diseases with ERP failure, poor efficacy or anatomical changes.
