Objective:To evaluate the efficacy and safety of quadruple therapy involving radiotherapy (RT), lenvatinib, anti-PD-1 antibody and GEMOX (oxaliplatin and gemcitabine) chemotherapy (quadruple therapy) in treatment cohort of patients with unresectable intrahepatic cholangiocarcinoma (ICC).Methods:The patients with recurrent, metastatic, or unresectable ICC underwent quadruple therapy at Zhongshan Hospital, Fudan University between September 2018 and May 2022 were selected. The data about efficacy and safety of quadruple therapy were collected in the hospital electronic medical record system. All patients were followed up regularly to obtain the long-term prognostic data until December 31, 2022. The efficacy, prognosis, and toxicity data were collected and analyzed.Results:A total of 41 patients were included in the analysis. After a median follow-up period of 15 months, disease progression was diagnosed in 36 patients (18 patients died), while 3 patients were lost to follow-up. The causes of death included liver failure induced by intrahepatic tumor progression ( n=6), distant metastases (lungs or brain, n=6), abdominal lymph node metastases ( n=3), cancer cachexia ( n=2), and unknown cause ( n=1). The median progression-free survival (PFS) was 11 months (95% CI: 9.2-12.8), and the median overall survival (OS) was 35 months (95% CI: 17.0-52.0). All patients experienced treatment-related adverse events (AEs) during the study treatment period. Of the 41 patients, 13 patients experienced at least once grade 3 or worse treatment-related AE, but all were manageable with symptomatic treatment. No treatment-related deaths were reported during the follow-up period. Conclusions:Radiotherapy (RT), lenvatinib, anti-PD-1 antibody and GEMOX in the treatment of unresectable ICC shows significant efficacy and good safety, which is worthy of clinical application.

ObjectiveTo systematically review the effect of neurofeedback training on cognitive function in the elderly within the framework of the International Classification of Diseases 11th Revision (ICD-11), and International Classification of Functioning, Disability and Health (ICF). MethodsA PICO framework was constructed. Randomized controlled trials on neurofeedback training for cognitive function in the elderly from PubMed, Web of Science, ProQuest, and CNKI up to July, 2023 were systematically reviewed. Methodological quality assessment of the included literature was performed using Physiotherapy Evidence Database scale. ResultsA total of 15 researches were included, from ten countries, involving 520 participants, who were healthy elderly individuals or those with mild cognitive impairment. Various neurofeedback waveforms were utilized, such as alpha, beta, theta, beta/alpha, and sensorimotor rhythm (SMR) waves. Intervention duration ranged from 20 to 90 minutes, with intervention frequencies spanning from a long-term intervention of 30 sessions over 12 weeks to a high-frequency short-term intervention of eight sessions over one week. The primary health outcomes focused on cognitive function, including memory, attention, inhibitory control and executive function. ConclusionNeurofeedback training can improve the cognitive function of the eldery, and alleviate cognitive aging.

Objective:To evaluate the clinical outcomes of internal fixation using double reverse traction reducers in the treatment of tibial plateau fractures.Methods:This study retrospectively examined the medical records of 48 patients who underwent surgical intervention for tibial plateau fractures at the Affiliated Hospital of Qingdao University between January 2021 and September 2022. The cohort, aged between 35 to 68 years (mean: 53.0±7.9 years), included 23 males and 25 females. Fractures were classified according to the Schatzker system, with 9 type III, 23 type IV, 11 type V, and 5 type VI fractures recorded. Patients were divided into two groups based on the surgical approach: the minimally invasive group underwent treatment with double reverse traction reducers for reduction and internal fixation in 24 cases, while the open group received conventional open reduction and internal fixation in 24 cases. Comparative parameters included operation duration, intraoperative blood loss, hospital stay, early postoperative knee mobility, and weight-bearing timelines. Postoperative radiographic images were appraised using the Rasmussen imaging score, and knee functionality was assessed at the final follow-up with the Hospital for Special Surgery (HSS) score and the International Knee Documentation Committee (IKDC) score.Results:The preoperative general data were statistically indifferent between groups ( P>0.05). All patients were followed for 13.5±4.3 months (range, 9.5-24 months). In the minimally invasive group, operative time was 88.96±19.04 minutes, intraoperative blood loss was 65±32 ml, and hospital stay was 11.8±3.9 days. Early postoperative knee joint activity commenced at 8.96±2.84 days, significantly earlier compared to the open group, which recorded 178.63±67.75 minutes of surgery, 114.16±65.05 ml blood loss, a 15.3±4.8 days hospital stay, and 16.83±4.09 days to knee joint movement. The difference was statistically significant ( P<0.05). No significant variation was observed in the time to bone healing between the minimally invasive group at 12.6±3.8 weeks and the open group at 13.21±4.98 weeks ( P>0.05). Rasmussen imaging criteria revealed 21 excellent and 3 good outcomes in the minimally invasive group, and 19 excellent and 5 good in the open group, with no statistical significance in the excellent-good rate differentiation ( P>0.05). Bone healing occurred within 3.2±0.8 months (range, 2.5-6.0 months), with 79% (19/24) in the minimally invasive group and 75% (18/24) in the open group achieving healing within 3 months. The open group had one incidence of superficial skin infection, and one patient in the minimally invasive group developed deep vein thrombosis (DVT); no other related complications were documented. Conclusion:Minimally invasive treatment of tibial plateau fractures using double reverse traction reducers offers significant benefits, including reduced surgical time, minimal blood loss, less soft tissue trauma, and enhanced joint function recovery. This approach is particularly advantageous in managing complex tibial plateau fractures compared to traditional open reduction and internal fixation methods.

Objective:To explore the diagnostic performance of patella-tilt angle and congruence angle in episodic patellar dislocation (EPD) and the quantitative measurements of the patellar and femoral axial parameters as well as their correlation with and contributions to the patellofemoral joint alignment with the knee extended.Methods:A case control study was conducted to analyze the radiological data of EPD patients (EPD group, n=106) and patients without patellar instability (control group, n=106) admitted to Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University from January 2016 to December 2019. Each group consisted of 55 females and 51 males with the age range of 14-45 years [(23.0±5.3)years], showing 1∶1 match. Axial parameters included patellar parameters (patellar width, patellar thickness, Wiberg angle and Wiberg index), femoral parameters [trochlear sulcus angle, trochlear sulcus depth, trochlear sulcus height, trochlear width ratio (lateral/medial), trochlear height ratio (lateral/medial), lateral trochlear inclination and trochlear groove medialization], and patellofemoral joint parameters (patellar tilt angle and congruence angle). The receiver operating characteristic (ROC) curve of patellofemoral joint parameters for the prediction of EPD was analyzed. Univariate analysis was performed to determine the difference of those axial parameters between the two groups. Pearson correlation analysis was used to identify the correlation between those bony parameters and patellofemoral joint parameters. Stepwise regression model was further established to determine the influencing factors and corresponding contributions for patellofemoral joint parameters. Results:When the optimal cut-off values of patellar tilt angle and congruence angle were 17.2° and 25.5°, the area under the ROC curve (AUC) for predicting EPD was 0.91 (95% CI 0.87-0.95, P<0.01) and 0.92 (95% CI 0.87-0.95, P<0.01), and the Youden index was 0.745 (sensitivity=83.96%, specificity=90.57%) and 0.717 (sensitivity=81.13%, specificity=90.57%). Univariate analysis showed that Wiberg index, femoral parameters and patellofemoral joint parameters were significantly different between the two groups (all P<0.01). For all patients, Pearson correlation analysis showed that patellar tilt angle was moderately to strongly correlated with Wiberg index, trochlear sulcus angle, trochlear sulcus depth, trochlear width ratio (lateral/medial), trochlear height ratio (lateral/medial) and lateral trochlear inclination ( r=0.51, 0.41, -0.62, 0.43, -0.49, -0.65, all P<0.01) and that congruence angle has a moderate correlation with trochlear sulcus angle, trochlear sulcus depth, trochlear width ratio (lateral/medial) and lateral trochlear inclination ( r=0.43,-0.59,0.38,-0.51, all P<0.01). For all patients, Stepwise regression model analysis showed that lateral trochlear inclination, trochlear sulcus depth, trochlear sulcus angle, Wiberg index and trochlear height ratio (lateral/medial) could explain 60% of the variation of patellar tilt angle ( R 2=0.60, P<0.01) and that trochlear sulcus depth, lateral trochlear inclination, trochlear groove medialization, trochlear sulcus angle and Wiberg index could explain 44% of the variation of congruence angle ( R 2=0.44, P<0.01). Conclusions:The patellar tilt angle and congruence angle are reliable quantitative indicators representing patellofemoral axial alignment, with a good diagnostic performance for EPD. Variations in the patellar and femoral bony structures of EPD patients are related to the patellofemoral axial alignment, with the axial parameters differently contributing to the patellofemoral alignment.

Objective:To evaluate the relationship of rotator cuff muscle function with shoulder abduction function after posterior superior rotator cuff tear via dynamic biomechanical study.Methods:By using the customized dynamic shoulder biomechanical testing system, seven freshly frozen cadaveric shoulders were used to stimulate shoulder abduction at 90° under four statuses: (1) intact rotator cuff with activation (normal rotator cuff group); (2) posterior superior rotator cuff tear with activation (posterior superior rotator cuff tear with activation group); (3) posterior superior rotator cuff tear with posterior superior rotator cuff deactivation (posterior superior rotator cuff tear with deactivation group); (4) none rotator cuff tissue above the geometric rotation center of the humeral head with deactivation (global tear group). The peak and stable value of middle deltoid force were used to evaluate biomechanical status in different rotator cuff tear conditions during shoulder abduction procedure. The peak subacromial pressure, average subacromial pressure, subacromial contact area, and subacromial force were used to evaluate subacromial pressed conditions under different rotator cuff tear conditions. The peak and stable ratio of glenohumeral contact force/middle deltoid force were used to evaluate shoulder stability under different rotator cuff tear conditions.Results:During dynamic abduction at 90°, the peak and stable value of middle deltoid force were (42.1±8.7)N and (29.9±7.4)N in normal rotator cuff group, (45.7±10.3)N and (30.5±7.2)N in posterior superior rotator cuff tear with activation group, and (48.4±13.4)N and (29.9±4.8)N in posterior superior rotator cuff tear with deactivation group (all P>0.05). But the peak and stable value of middle deltoid force were (69.7±9.7)N and (53.7±8.9)N in global tear group, significantly increased compared with other three groups (all P<0.05). The elevated middle deltoid force increased the subacromial contact pressure between glenohumeral head and acromion. The peak subacromial pressure, average subacromial pressure, subacromial contact area, and subacromial force were (0.40±0.05)MPa, (0.22±0.03)MPa, (7.71±5.09)mm 2, and (1.66±1.06)N respectively in normal rotator cuff group, (0.41±0.05)MPa, (0.26±0.07)MPa, (12.71±11.35)mm 2, and (2.93±2.46)N respectively in posterior superior rotator cuff tear with activation group, and (0.50±0.12)MPa, (0.26±0.07)MPa, (17.29±9.11)mm 2, and (4.09±1.46)N respectively in posterior superior rotator cuff tear with deactivation group (all P>0.05). However, the peak subacromial pressure, average subacromial pressure, subacromial contact area, and subacromial force were (3.64±1.70)MPa, (0.98±0.49)MPa, (47.63±11.91)mm 2, and (45.48±23.86)N respectively in global tear group, significantly higher than those in other three groups (all P<0.05). The peak and stable ratio of glenohumeral contact force/middle deltoid force were 2.24±0.30 and 2.46±0.13 in normal rotator cuff group, 2.21±0.19 and 2.52±0.08 in posterior superior rotator cuff tear with activation group, and 2.03±0.14 and 2.42±0.16 in posterior superior rotator cuff tear with deactivation group (all P>0.05). However, the peak and stable ratio of glenohumeral contact force/middle deltoid force were 1.40±0.14 and 1.52±0.41 in global tear group, significantly higher than those in other three groups (all P<0.05). No significant differences of the above parameters were observed in posterior superior rotator cuff tear with activation group, posterior superior rotator cuff tear with deactivation group and global tear group (all P>0.05). Conclusions:After posterior superior rotator cuff tear, rotator cuff muscle function does not affect the whole abduction function of shoulder. When the size of rotator cuff tear involves the whole superior humeral head rotation center, the normal abduction function of shoulder will be significantly impaired.

Objective:To investigate the correlation between intraplaque hemorrhage (IPH) and new-onset embolic cerebral infarction after basilar artery angioplasty or stenting.Methods:Consecutive patients with severe basilar atherosclerotic stenosis underwent basilar artery angioplasty or stenting in the Department of Neurology, Guangdong Provincial Hospital of Chinese Medicine from January 2015 to February 2022 were retrospectively enrolled. High resolution magnetic resonance vessel wall imaging (HRMR-VWI) and diffusion-weighted imaging (DWI) were performed within one week before procedure, and brain DWI or CT examination was performed within 72 h after procedure to determine the patients with new-onset embolic cerebral infarction.Results:A total of 32 patients were enrolled in the analyze. IPH existed in 10 patients with basilar artery culprit plaque, and 5 had new-onset embolic cerebral infarction after procedure. The incidence of embolic cerebral infarction in the IPH group was significantly higher than that in the non-IPH group (50% vs. 0%; P=0.001). The proportion of patients with IPH in the embolic cerebral infarction group was significantly higher than that in the non-embolic cerebral infarction group (100% vs. 18.5%; P=0.001). Conclusion:IPH may be associated with new-onset embolic cerebral infarction after basilar artery angioplasty or stenting.

Objective:To compare the thickness of the macular ganglion cell inner plexiform layer (mGCIPL) in patients with a history of laser photocoagulation (LP) versus intravitreal injection of ranibizumab (IVR) for retinopathy of prematurity (ROP).Methods:A retrospective clinical study. From June 2020 to January 2021, 70 eyes of 35 children with a history of surgery for ROP in Shenzhen Eye Hospital were included in the study. Among them, 18 males had 36 eyes, and 17 females had 34 eyes. The average age was 5.54±1.04 years. There were 18 patients (36 eyes) in LP group and 17 patients (34 eyes) in IVR group. There was no significant difference in age ( t=-1.956), sexual composition ratio ( χ2=0.030), birth gestational age ( t=-1.316) and birth weight ( t=-1.060) between the two groups ( P=0.059, 0.862, 0.197, 0.297). All the eyes underwent the examination of optical coherence tomography (OCT). An elliptical region of 14.13 mm 2 centered on macular fovea was scanned according to the macular cube 512×128 model of the Cirrus HD-OCT 5000. The software was used to automatically divide macular fovea into six sectors (superior, inferior, temporal-superior, temporal-inferior, nasal-superior and nasal-inferior) and the average and minimum thickness of mGCIPL. t test was used to compared mGCIPL thickness between two groups using independent samples. Pearson correlation analysis was used to evaluate the correlation between mGCIPL thickness and age, birth gestational age, birth weight. Results:Patients in IVR group had significantly decreased mGCIPL thickness than that in LP group in the six sectors (superior, inferior, temporal-superior, temporal-inferior, nasal-superior and nasal-inferior) and the average and minimum ( t=6.484, 6.719, 7.682, 7.697, 5.151, 5.008, 7.148, 6.581; P<0.05). The thickness of mGCIPL was not significantly correlated with age, birth gestational age, birth weight ( P>0.05). Conclusion:The thickness of mGCIPL in patients with IVR treatment history is thinner than that in LP treatment.

Objective:To observe the changes of macular morphology and best corrected visual acuity (BCVA) in children with retinopathy of prematurity (ROP) after single treatment of laser photocoagulation or intravitreal injection of ranibizumab (IVR) by optical coherence tomography angiography (OCTA).Methods:A cross sectional study was conducted.Fourteen cases (23 eyes) of ROP children with a treatment history aged 4-10 years were enrolled as the ROP group in Shenzhen Eye Hospital from April to August 2018, with 8 cases (16 eyes) of age-matched full-term children as control group.Among the ROP group, 9 cases (14 eyes) receiving photocoagulation were set as the photocoagulation group and 5 cases (9 eyes) receiving IVR as the injection group.The 3 mm×3 mm scanning mode of OCTA was adopted to measure the area of foveal avascular zone (FAZ), FAZ morphological index, superficial retinal vascular density (VD) and superficial retinal perfusion density (PD), and the B-scan mode was used to determine the central foveal thickness (CFT). BCVA of all children was recorded and analyzed.This study adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Shenzhen Eye Hospital (No.b-03). Written informed consent was obtained from guardians prior to any examination.Results:Compared with the control group, there was smaller area of FAZ, more irregular FAZ morphology and thicker CFT in the ROP group.The central fovea of macula in the laser photocoagulation group was shallow and almost indiscernible, and FAZ morphology was irregular.The FAZ area, FAZ morphological index, VD and PD in the ROP group were (0.09±0.08) mm 2, 0.51±0.25, (19.18±2.50)mm/mm 2 and 0.35±0.04, respectively, which were significantly lower than (0.32±0.08)mm 2, 0.68±0.07, (20.94±0.93)mm/mm 2, 0.38±0.02, respectively in the control group ( t=-8.03, -3.14, -3.02, -2.52; all at P<0.05). The CFT in the ROP group was (215.00±21.32) μm, which was significantly thicker than (164.29±20.20) μm in the control group ( t=8.91, P<0.05). There was no statistical difference in BCVA between the two groups ( t=0.16, P=0.87). The CET in the laser photocoagulation group was significantly thicker than that in the injection group ( t=3.50, P=0.01). Conclusions:There are obvious morphology changes of macula in ROP children with single treatment history of laser photocoagulation or IVR, while the BCVA is not significantly affected by the treatment.

The clinical application of immune checkpoint inhibitors (ICIs) has significantly improved the prognosis of hepatocellular carcinoma (HCC) patients. With the widespread applica-tion of ICIs in HCC, the management of immune-related adverse events (irAE) gained more and more attention. However, the complicated disease characteristics and various combination therapies in HCC throw out challenges to irAE management. Therefore, the editorial board of the 'Chinese expert consensus on the management of immune-related adverse events of hepatocellular carcinoma treated with immune checkpoint inhibitors (2021 edition)' organizes multidisciplinary experts to discuss and formulate this consensus. The consensus focuses on issues related to HCC irAE manage-ment, and puts forward suggestions, in order to improve standardized and safety clinical medication, so as to maximize the benefits of immunotherapy for patients.
