Liver cancer is the third leading cause of cancer-related deaths worldwide， among which hepatocellular carcinoma （HCC） accounts for approximately 90% in primary liver cancer. The advances in diagnostic and treatment tools， along with a deeper understanding of their application， are transforming the treatment modality for patients. The application of these innovations in clinical practice faces challenges and requires guidance， and related clinical practice guidelines provide the latest recommendations for the management of HCC patients and conduct a comprehensive review of related data. In the 2024 EASL guidelines， a multidisciplinary team from multiple specialties conducts a multi-parameter assessment of individual risks and benefits from the perspective of patients.

Objective To observe the relationship between functional connectivity(FC)of frontoparietal network(FPN)and cognitive function in patients with cerebral small vessel disease(CSVD)using resting-state functional MRI(rs-fMRI).Methods rs-fMRI of 50 CSVD patients with cognitive impairment(CI group),65 CSVD patients with normal cognition(NC group)and 60 healthy controls(HC group),as well as outcomes of neuropsychological tests were retrospectively analyzed.Brain regions with different FC of FPN were compared among 3 groups and between each 2 groups.Partial correlation analysis was used to evaluate the correlations of FC of brain regions value being statistically different between CI and NC groups and cognitive scores.Results Significant differences of FC in bilateral cingulate gyrus,left middle frontal gyrus,right supramarginal gyrus,right inferior parietal lobule and right medial superior frontal gyrus were found among groups(FWE correction,all P＜0.05).Compared with NC group,FC of left cingulate gyrus decreased,of right inferior frontal gyrus and right medial superior frontal gyrus increased in CI group(FWE correction,all P＜0.05).The decreased FC value of left cingulate gyrus was negatively correlated with clock drawing test score in CSVD patients(r=-0.159,P=0.049).Conclusion CSVD patients with or without CI had extensive abnormal FC of FPN,and the left cingulate gyrus was associated with patient's cognitive function.

A middle-aged male came to Peking Union Medical College Hospital for treatment because of "pain for 10+ years, aggravated with emotional instability for 5 years". The patient's pain had a huge impact on life, with poor results even after repeated diagnosis and treatment in other hospitals. After multi-disciplinary discussion, it had been clarified that the pain was mainly caused by gout. The disease was heavily influenced by psychosocial factors. Therefore, the patient fits the diagnosis of "Psychological and Behavioral Factors Affecting Physical Diseases". The multi-disciplinary comprehensive management of the patient was carried out to identify and treat psychological factors affecting other medical conditions. After this mental treatment was performed, the patient's conditions significantly improved. The diagnosis and treatment of this patient demonstrates the importance of the multi-disciplinary treatment team for somatic symptoms (disorders).

Objective To introduce the robotic-assisted left hemicolectomy and Soave procedure and its clinical outcome for Hirschsprung's allied disease.Methods From June 2015 to November 2022,19 cases diagnosed with Hirschsprung's allied disease underwent left colectomy and Soave pull-through by using the da Vinci surgical system,and the clinical data of 19 children were summarized and analyzed.A four trocar technique was used.The left colon was firstly mobilized by laparoscopy from splenic flexure of colon to the level of peritoneal reflection,then the rectum was mobilized by Robotic system to the level of dentate line.A circumferential incision was made in the mucosa at 0.5 cm proximal to the dentate line.The upward submucosal dissection was carried out for approximately 1-2 cm.The left colon was pulled through the anal canal and resected.The coloanal anastomosis was fashioned manually 0.5 cm above the dentate line.21 cases underwent conventional laparoscopic-assisted Soave surgery were used as control group.Results All patients were successfully operated.Compared with conventional laparoscopic-assisted Soave surgery,the operation time was significantly prolonged(P＜0.01),the intraoperative blood loss was significantly reduced(P＜0.01),and the overall postoperative complication rate was significantly reduced(11％VS.43％,P＜0.05).There were no serious complications such as major bleeding and death.Conclusion Robotic-assisted left hemicolectomy and Soave procedure are safe and feasible in the treatment of Hirschsprung's allied disease,with few postoperative complications and satisfactory clinical outcome.

Objective To explore the key of post-processing techniques for continuous and symmetrical display of cervical verte-bral bony structures using curve planar reformation(CPR).Methods Data from 150 patients who underwent cervical spine CT scans were collected and divided into three groups based on cervical curvature:normal,straightened,and kyphotic.A multi-slice CPR post-processing method was designed,using the display rate of structures such as C2/C3 to C6/C7 intervertebral foramina,uncovertebral joints,facet joints,and pedicles of vertebral arch as the measurement index to find the optimal site and angle for CPR baseline selection.Additionally,the consistency of the intervertebral foramen diameter and area measurements on both sides of the CPR baseline level,as well as the normal appearance of the cervical vertebral bony structures during baseline translation were observed.Results The optimal site for the CPR baseline was C4/C5 with a best angle of 100° for normal or straightened cervical curvature,and C5/C6 with a best angle of 100° for kyphotic curvature.At these baseline levels,the measurements of the longitudinal and transverse diameters,as well as the area,of the intervertebral foramina on both sides were similar,providing a valuable comparison.When translating the baseline forwards and backwards,CPR could continuously and symmetrically display the cervical vertebral bony structures clearly.Conclusion Performing multi-slice CPR image post-processing based on the aforementioned baseline sites and angles aids in the comparison of the left and right sides,facili-tating the convenient and intuitive detection of subtle abnormalities in cervical vertebral bony structures.

Objective:To investigate the impact of group-based rehabilitation exercise on motor and non-movement symptoms of Parkinson's disease(PD).Methods:A total of 88 patients from out-patient and in-patient services at our hospital were randomly assigned to an early exercise group(E-EG), a late exercise group(L-EG), and a control group(CG)using a randomized delayed-start design.Patients in the E-EG carried out a rigorous, formal group exercise program, one hour per session, twice per week, for 18 months(May 2018-November 2019). Patients in the L-EG took part in the exercise program in the final 6-12 months of the study.We assessed outcomes using the Unified Parkinson's Disease Rating Scale(UPDRS), Parkinson's disease questionnaire-39(PDQ-39 Q), trail-making test part A & B, nine-hole peg test(9-HPT), 30 second sit to stand test(30s SST), 10 m walk test(10 m W), mini-balance evaluation systems test(Mini-BEST), Fullerton Advanced Balance(FAB)Scale and time up and go(TUG)test.Results:Compared with pre-exercise levels, patients with PD in the E-EG had lower performance in UPDRS(17.5±8.3 vs.20.0±8.6, t=-2.2, P=0.02)and lower performance in PDQ-39(27.2±2.1 vs.29.0±9.8, t=-2.6, P=0.001)after exercise.Moreover, compared with pre-exercise levels, patients with PD in the E-EG showed decreased post-exercise performance in trail-making test part B(114.2±25.5 vs.129.8±28.4, t=-2.3, P=0.02)and in 9-HPT(33.7±7.3 vs.39.6±9.3, t=-2.6, P=0.001). Conclusions:The practice of group-based rehabilitation exercise can improve movement abilities and quality of life in PD patients, especially if implemented early.Targeted rehabilitation exercise should be taken as part of the treatment strategy for PD patients as early as possible to deliver the best benefits.

ObjectiveTo observe the clinical efficacy and safety of treating mediate-risk pure ground glass pulmonary nodules （pGGNs） based on the state theory. MethodsA prospective clinical randomized controlled trial was used. Totally 141 cases of mediate-risk pGGNs were divided into treatment group （92 cases） and control group （49 cases） according to the random table method. The treatment group was given the basic Sanjie Formula （基础散结方） orally with modification according to the identification of traditional Chinese medicine （TCM） state， 1 dose per day， 3 months as a course of treatment.Three months after the treatment patients were checked by CT. Patients who were clinically judged as cure， moderate to low risk， and turned to surgical resection do not carry out a second course of treatment，and the rest of the patients continued to complete the second courses. Patients in the control group did not receive any treatment and were only followed up periodically. Patients in both groups received a CT review 3 months and 6 months after enrolled. Comprehensive curative effect was evaluated according to the reduction rate of the area of pulmonary nodules shown in chest CT， to further explore the clinical effective difference for patients at different TCM state； the risk of malignancy index （Mayo score） was calculated by Mayo model at enrollment and 3 months and 6 months after enrolled. Adverse events were monitored continuously during the study. ResultsDuring the follow-up， 8 cases in the treatment group and 7 cases in the control group were lost. A total of 126 cases completed the whole process， including 84 cases in the treatment group and 42 cases in the control group. The total effective rates at 3 months and 6 months of the treatment group were 46.15% （30/65） and 45.71% （32/70） in the treatment group， while the total effective rates at 3 months and 6 months in the control group were 12.5% （4/32） and 10.00% （4/40）. Compared with the control group， the comprehensive curative effect of 3 months and 6 months of enrollment in treatment group was significantly better than that in corresponding control group （P＜0.01）. The pulmonary nodule area and Mayo score in the treatment group decreased after 3 and 6 months of enrollment （P＜0.01）. In contrast， there was no statistically significant difference in nodule area between pre- and post-enrollment time points in the control group （P＞0.05）， and probability of Mayo risk increased in the control group after 6 months of enrollment compared to pre-enrollment （P＜0.05）. Among the 84 patients in the treatment group， there were 15 cases of qi deficiency state， 7 cases of yin deficiency state， 5 cases of yang deficiency state， 20 cases of qi depression state， 32 cases of damp-heat state， and 5 cases of harmonious state； the difference in the distribution of the total clinical effective rate of the patients with different TCM states after treatment was statistically significant （P＜0.05）， and the total effective rate of two-by-two comparison of qi depression state was higher （13/20，65.00%） than that of the total effective rate of damp-heat state （8/32，25.00%， P＜0.00833）. There were no significant changes in blood routine， urine routine， liver function and kidney function in both groups， and no adverse events occurred. ConclusionTreating mediate-risk pGGNs based on the state theory can effectively reduce the area of pulmonary nodules and inhibit the growth of malignant risk of pulmonary nodules.

BACKGROUND: The presence of fibrosis is a criterion for subtype classification in the newly updated hypersensitivity pneumonitis (HP) guidelines. The present study aimed to summarize differences in clinical characteristics and prognosis of non-fibrotic hypersensitivity pneumonitis (NFHP) and fibrotic hypersensitivity pneumonitis (FHP) and explore factors associated with the presence of fibrosis. METHODS: In this prospective cohort study, patients diagnosed with HP through a multidisciplinary discussion were enrolled. Collected data included demographic and clinical characteristics, laboratory findings, and radiologic and histopathological features. Logistic regression analyses were performed to explore factors related to the presence of fibrosis. RESULTS: A total of 202 patients with HP were enrolled, including 87 (43.1%) NFHP patients and 115 (56.9%) FHP patients. Patients with FHP were older and more frequently presented with dyspnea, crackles, and digital clubbing than patients with NFHP. Serum levels of carcinoembryonic antigen, carbohydrate antigen 125, carbohydrate antigen 153, gastrin-releasing peptide precursor, squamous cell carcinoma antigen, and antigen cytokeratin 21-1, and count of bronchoalveolar lavage (BAL) eosinophils were higher in the FHP group than in the NFHP group. BAL lymphocytosis was present in both groups, but less pronounced in the FHP group. Multivariable regression analyses revealed that older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors for the development of FHP. Twelve patients developed adverse outcomes, with a median survival time of 12.5 months, all of whom had FHP. CONCLUSIONS Older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors associated with the development of FHP. Prognosis of patients with NFHP was better than that of patients with FHP. These results may provide insights into the mechanisms of fibrosis in HP.

Novel cancer immunotherapy can treat tumors through regulating innate immunity and adaptive immune system. cGMP-AMP synthase (cGAS) is a key regulator of innate immune response to both exogenous and endogenous DNA. After recognizing the cytoplasmic DNA, cGAS produces the second messenger cyclic GMP-AMP (cGAMP), which subsequently combines with the adaptor STING (also known as MITA, MPYS and ERIS) to mediate innate immunity by inducing the production of type I interferons and inflammatory cytokines. Recent studies have revealed that the cGAS/STING signaling pathway can be activated by tumor-derived DNA and by-products of genomic instability and affect the incidence and development of tumors, which plays a critical role in the natural antitumor immunity across cancer types and immune checkpoint blockade therapy. In this article, current understanding of cGAS/STING signaling pathway in tumors was summarized, the pivotal role in tumor immunity and radiotherapy was highlighted, and the potential targeted or alternative therapy of this signaling pathway was reviewed.
