Objective To analyze the application effects of artificial intelligence (AI) software and Mimics software in preoperative three-dimensional (3D) reconstruction for thoracoscopic anatomical pulmonary segmentectomy. Methods A retrospective analysis was conducted on patients who underwent thoracoscopic pulmonary segmentectomy at the Second People's Hospital of Huai'an from October 2019 to March 2024. Patients who underwent AI 3D reconstruction were included in the AI group, those who underwent Mimics 3D reconstruction were included in the Mimics group, and those who did not undergo 3D reconstruction were included in the control group. Perioperative related indicators of each group were compared. Results A total of 168 patients were included, including 73 males and 95 females, aged 25-81 (61.61±10.55) years. There were 79 patients in the AI group, 53 patients in the Mimics group, and 36 patients in the control group. There were no statistical differences in gender, age, smoking history, nodule size, number of lymph node dissection groups, postoperative pathological results, or postoperative complications among the three groups (P>0.05). There were statistical differences in operation time (P<0.001), extubation time (P<0.001), drainage volume (P<0.001), bleeding volume (P<0.001), and postoperative hospital stay (P=0.001) among the three groups. There were no statistical differences in operation time, extubation time, bleeding volume, or postoperative hospital stay between the AI group and the Mimics group (P>0.05). There was no statistical difference in drainage volume between the AI group and the control group (P=0.494), while there were statistical differences in operation time, drainage tube retention time, bleeding volume, and postoperative hospital stay (P<0.05). Conclusion For patients requiring thoracoscopic anatomical pulmonary segmentectomy, preoperative 3D reconstruction and preoperative planning based on 3D images can shorten the operation time, postoperative extubation time and hospital stay, and reduce intraoperative bleeding and postoperative drainage volume compared with reading CT images only. The use of AI software for 3D reconstruction is not inferior to Mimics manual 3D reconstruction in terms of surgical guidance and postoperative recovery, which can reduce the workload of clinicians and is worth promoting.

Consciousness disorders following traumatic brain injury (TBI) are alterations in consciousness due to damage to the brain parenchyma and/or brain vessels. As the number of TBI patients continues to increase, so does the number of patients with consciousness disorders following TBI. The patients′ quality of life was seriously affected due to a long course of illness and loss of most of independence. However, at present, the mechanisms of consciousness disorders in TBI are still unknown. The assessment of conscious state in patients with consciousness disorders following TBI mainly depends on scales, resulting in a high rate of misdiagnosis. Common interventions, including pharmacological interventions such as amantadine and zolpidem, as well as non-pharmacological interventions such as neuromodulation and sensory stimulation programs, fail to achieve extensive efficacy. Therefore, there is an urgent need for more accurate assessment indicators as well as effective therapeutic interventions. Various neurophysiological activities sustained by sleep are crucial for consciousness. Sleep regularity is likely to reflect the conscious state of patients with consciousness disorders following TBI. Sleep regularity is generally reflected through sleep architecture, including circadian rhythms and various sleep characteristics. Therefore, the authors reviewed the research progress in the application of sleep architecture in the assessment and recovery of conscious state in patients with consciousness disorders following TBI, so as to provide reference for its clinical application.

Objective:To analyze the disease characteristics, diagnosis and treatment methods of venous pulsatile tinnitus treated by intervention of sigmoid sinus.Methods:Fifty patients (from Shandong Provincial ENT Hospital, Shandong University between February 2014 and July 2020) with venous pulsatile tinnitus treated by sigmoid sinus surgery were analyzed retrospectively. The tinnitus characteristics, imaging findings, surgical methods, intraoperative findings and postoperative tinnitus changes were recorded. The patients were followed up for 6-12 months. The sign rank sum test was used to analyze the difference in tinnitus grading before and after surgery. There were 50 patients with unilateral venous pulsatile tinnitus, including 49 females and 1 male. The age ranged from 17 to 67 years, with a median age of 44 years. There were 45 cases of right tinnitus and 5 cases of left tinnitus. The degree of tinnitus before operation was grade Ⅱ or above, including 4 cases of gradeⅡ, 11 cases of grade Ⅲ, 22 cases of grade Ⅳ and 13 cases of grade Ⅴ.Results:Thirty-seven cases were cured, 8 cases were ineffective (no change in tinnitus), 3 cases were markedly effective (tinnitus grade decreased by 3 in 2 cases, 4 in 1 case), and 2 cases were effective (tinnitus grade decreased by 1). The difference of tinnitus grade before and after operation was statistically significant ( Z=-5.70, P<0.05). Temporal bone CT showed 36 cases of sigmoid diverticulum (including 17 cases with sigmoid sinus dehiscence), 12 cases of sigmoid sinus dehiscence and 2 cases of absence of the temporal bone cortex abutting to sigmoid sinus. Thirty-five cases were performed with closure of sigmoid sinus diverticulum, 4 cases were performed with resurfacing of the sigmoid plate, 5 cases were performed with narrowing of sigmoid sinus, 4 cases were performed with simple opening of pre sigmoid mastoid air chamber, 1 case of opening was performed with pre sigmoid mastoid air chamber combined with narrowing of sigmoid sinus, and 1 case was performed with opening of pre sigmoid mastoid air chamber combined with closure of sigmoid sinus diverticulum. Conclusions:Venous pulsatile tinnitus is common in women. The common causes may be sigmoid sinus wall abnormalities such as sigmoid sinus diverticulum and perisigmoid bone defect. Imaging examinations are helpful for diagnosis. Venous pulsatile tinnitus can be treated with surgery.

Objective To evaluate the efficacy and safety of transcatheter arterial chemoembolization(TACE)followed by hepatic arterial infusion chemotherapy(HAIC)combined with TKI drugs and PD-1 inhibitors as the first-line treatment for advanced hepatocellular carcinoma(HCC).Methods We retrospectively analyzed the data of 70 patients with advanced HCC treated in the Department of Oncology of Guangdong Provincial Hospital of Integrated Traditional Chinese and Western Medicine between July,2020 and June,2023.23 of the patients received TACE combined with HAIC and TKI(TACE+HAIC+TKI group)and 47 received TACE combined with HAIC,PD-1 inhibitors and TKI(TACE+HAIC+PD-1+TKI group).The clinical characteristics,laboratory test results,efficacy,outcomes and adverse events of the patients were compared between the two groups.Results The TACE+HAIC+TKI and TACE+HAIC+PD-1+TKI groups had significantly different objective remission rates(ORR;60.87%vs 36.17%,P=0.031),comparable disease control rates(95.65%vs 93.62%,P=0.068),and different median progression-free survival(PFS)time(10.2 vs 11.8 months,P=0.003)and median overall survival(OS)time(15.7 vs 19.5 months,P=0.035).After propensity score matching(PSM),the median PFS and OS time of the two groups was 10.1 vs 14.5 months(P=0.024)and 14.2 vs 21.2 months(P=0.221),respectively.The 1-year PFS rates of the 2 groups were 24.0%vs 52.2%,and the 1-,2-and 3-year OS rates were 72.3%vs 93.1%,23.9%vs 63.8%,and 23.9%vs 36.5%,respectively.The incidence of proteinuria was significantly higher in TACE+HAIC+PD-1+TKI group than in TACE+HAIC+TKI group(21.28%vs 0,P=0.025),but the incidences of grade 3-4 treatment-related adverse events were all similar between the two groups.Conclusion The first-line treatment with TACE+HAIC+PD-1+TKI is safe and effective for advanced HCC and can significantly prolong the survival of the patients.

Objective To explore growth pattern of neo-aortic root as well as development of neo-aortic regurgitation after arterial switch operation (ASO) for Taussig-Bing anomaly. Methods From 2002 to 2017, the patients who received ASO, and were discharged alive from Shanghai Children’s Medical Center and followed up for more than 3 years were retrospectively involved in this study. Results A total of 127 patients were enrolled. There were 98 (77.2%) males, the median age at ASO was 73.0 d and the average weight was 4.7 kg. Forty-five (35.4%) children were complicated with mild or mild-to-moderate pulmonary insufficiency (PI) before ASO. The average follow-up time was 7.0 years. During the follow-up, 14 (11.0%) children presented moderate or greater neo-aortic regurgitation (neo-AR). The diameter of neo-aortic annulus and sinus of Valsalva was beyond normal range during the entire follow-up. The average diameter of neo-aortic annulus was 18.0 mm at 5 years and 20.5 mm at 10 years. The average diameter of sinus of Valsalva was 25.9 mm at 5 years and 31.1 mm at 10 years. Neo-AR continued to develop over time. The diameter of children who developed moderate or greater neo-AR was constantly larger than that of children who did not (χ2=18.3, P<0.001). Preoperative mild or mild-to-moderate PI was an independent risk factor for the development of moderate or greater neo-AR during mid-to-long term follow-up (c-HR=3.46, P=0.03). Conclusion The diameters of neo-aortic annulus and sinus of Valsalva of Taussig-Bing children who receive ASO repair continue to expand without normalization. The dilation of annulus correlates with the development of neo-AR. PI before ASO repair increases the risk of neo-AR development.

Adjuvant chemoradiotherapy,molecular targeted therapy,and immunotherapy are frequently employed to extend the survival of patients with advanced gastric cancer(GC).However,most of these treatments have toxic side effects,drug resistance,and limited improvements in survival and quality of life.Therefore,it is crucial to discover and develop new medications targeting GC that are highly effective and have minimal toxicity.In previous studies,the total terpene extract from the stem of Celastrus orbiculatus demonstrated anti-GC activity;however,the specific mechanism was unclear.Our research utilising co-immunoprecipitation-mass spectrometry(Co-IP-MS),polypyrimidine tract binding protein 1(ptbp1)clustered regularly interspaced short palindromic repeat-associated protein 9(Cas9)-knockout(KO)mouse model,tissue microarray,and functional experiments suggests that alpha actinin-4(ACTN4)could be a significant biomarker of GC.PTBP1 influences actin cytoskeleton restructuring in GC cells by interacting with ACTN4.Celastrus orbiculatus stem extract(COE)may directly target ACTN4 and affect the interaction between PTBP1 and ACTN4,thereby exerting anti-GC effects.

Objective:To investigate the clinical and radiologic characteristics of children with congenital pseudarthrosis of the tibia (CPT) in a single center.Methods:This is a retrospective case series study. According to inclusion and exclusion criteria, clinical data of 497 children(507 limbs) with CPT who were treated at Department of Orthopedics, the Children′s Hospital Affiliated to Xiangya School of Medicine, Central South University from January 2011 to December 2020 were collected. Baseline data included gender, age at initial visit, age at onset of symptoms, accompanying symptoms, domicile, whether first treated at our hospital, and treatment-related information such as surgical or conservative treatment, surgical complications, etc., were extracted and analyzed using the health information system. Imaging data of the children, including Crawford classification, bilateral leg lengths, presence of fibular pseudarthrosis, and location of pseudarthrosis along the tibia segment, were analyzed using the Picture Archiving and Communication System. Data were compared using independent sample t test or χ2 tests. Results:Among 497 children with CPT, there were 305 males (61.4%) and 192 females (38.6%). The age at initial visit was (3.6±3.2) years (range: 0.1 to 16.2 years). Neurofibromatosis type 1 (NF1) symptoms were positive in 340 children (68.4%), and negative in 157 children (31.6%). Among NF1-positive children, those with symptoms onset before 1 year of age were significantly more than NF1-negative children (74.1%(252/340) vs. 66.2%(104/157); χ2=9.24, P=0.001), and the proportion of fractures (92.9%,316/340) was significantly higher than that in the NF1-negative group (84.7%,133/157) ( χ2=8.33, P=0.004). According to imaging data, Crawford type Ⅳ was the most common type, with 321 limbs (63.3%), followed by type Ⅱ in 100 limbs (19.7%), type Ⅲ in 54 limbs (10.7%) and type Ⅰ in 32 limbs (6.3%). Pseudarthrosis occurred in the proximal third of the tibia in 14 limbs (2.8%), in the middle third in 185 limbs (36.5%), and in the distal third in 308 limbs (60.8%). Seventy-four children (14.9 %) had associated fibular pseudarthrosis. The lateral proximal tibial angle was 86.91°±5.21°(range: 72.17° to 102.08°), and the lateral distal tibial angle was 87.27°±10.73°(range: 51.07° to 128.17°). A total of 421 children (84.7%) underwent surgical treatment with (3.1±2.4) surgeries performed per child (range:0 to 12 surgeries); 76 children (15.3%) received conservative treatment. Postoperative complications mainly included ankle valgus (77 cases), leg length discrepancy (71 cases),refracture (48 cases), osteomyelitis (11 cases), and hardware failure (10 cases). NF1-positive children underwent more surgeries than NF1-negative children ((5.1±2.2)times vs.(2.1±1.8)times; t=14.93, P<0.01). Conclusions:Crawford type Ⅳ is the most common type of CPT in children in this study. CPT predominantly occurs in the middle or distal third of the tibia. The majority of children with CPT experienced symptoms and were seen at outpatient clinics before the age of 3 years. The main surgical complications currently associated with CPT treatment are ankle valgus and leg length discrepancy. Compared with CPT without NF1, children with NF1-positive CPT tend to have earlier symptom onset and may require more frequent treatments.
