Objective To analyze the influencing factors of chronic obstructive pulmonary disease(COPD)complicating pulmonary interstitial fibrosis,and to establish a nomogram prediction model.Methods The clinical data of 195 patients with COPD admitted and treated in this hospital from January 2019 to Feb-ruary 2021 were retrospectively analyzed.The factors possibly affecting the patients with COPD complicating pulmonary interstitial fibrosis were collected,and the patients were divided into 2 groups according to whether having pulmonary interstitial fibrosis.The independent risk factors were analyzed and screened by the multi-variate logistic regression.Then the nomogram prediction model was constructed.Results Among the includ-ed 195 cases of COPD in this study,there were 50 cases(25.64％)of complicating pulmonary interstitial fi-brosis.The univariate and multivariate logistic regression analysis results showed that the smoking history,duration of COPD,frequency of acute exacerbations onset,serum transforming growth factor β1(TGF-β1),basic fibroblast growth factor(bFGF)and angiotensin Ⅱ(AngⅡ)were the independent influencing factors of COPD complicating pulmonary interstitial fibrosis(P＜0.05).The nomogram model was constructed accord-ing to the results of multivariate analysis results,and the area under the receiver operating characteristic(ROC)curve was 0.956(95％CI:0.930-0.983),the average absolute error of internal verification by the Bootstrap method was 0.025,and the prediction model performance basically fitted the ideal model.Conclusion The nomogram model constructed by this study for predicting the pulmonary interstitial fibrosis in COPD patients has high accuracy and distinction degree.

Thrombocytopenia is one of the common complications of cirrhotic patients, which can induce an increasing bleeding risk and closely correlate with bleeding following invasive procedures. Consequently, how to respond to thrombocytopenia is crucial for improving the prognosis of patients with cirrhosis. This article reviews the main mechanisms of cirrhosis concurrent with thrombocytopenia, as well as the corresponding clinical management strategies.

Objective:To investigate effect of Yiqi Huoxue Huazhuo Jiedu Prescription(YHHJP)on inflammatory factors of brain tissues,tight junction between brain and colon tissues,intestinal flora and bacterial metabolites in cerebral ischemia reperfusion injury(CIRI)rats based on brain-gut axis.Methods:Fifty male SD rats of SPF grade were randomly divided into sham-operation group(Sham),model group(MCAO),low,medium,high doses YHHJP groups(TCM-L/TCM-M/TCM-H).Middle cerebral artery occlusion model was established according to Zea Longa methods.Neurological function defects were detected 3 days after administra-tion.TTC staining was used to calculate infarct size of brain tissue.Pathological changes of brain tissue were observed by Nissl staining,and pathological changes of brain and colon tissues were observed by HE staining.IL-1β,IL-6,TNF-α in brain tissue and LPS con-tent in serum were detected by ELISA,and D-LA content in serum was detected by biochemical method.Gene expressions of ZO-1 and Claudin-5 in brain tissue and gene expressions of ZO-1,Claudin-1 in colon tissue were studied by Real-time fluorescent quantita-tive PCR.Intestinal flora were detected by 16S rDNA high-throughput sequencing.Results:Compared with Sham group,pathological damage of brain and colon tissue were serious in MCAO group,intestinal flora structure was significantly different,neural function im-pairment was aggravated,infarct size was increased,IL-1β,IL-6,TNF-α contents in brain tissue,and LPS,D-LA contents in serum were increased,gene expressions of ZO-1 and Claudin-5 in brain tissue and gene expressions of ZO-1 and Claudin-1 in colon tissue were decreased significantly(P<0.05).Compared with MCAO group,pathological damage of brain and colon tissue of rats were relieved in TCM-L,TCM-M,TCM-H groups,disturbance of intestinal microflora microecology was improved,neurological function impairment and infarct size were markedly decreased,IL-1β,IL-6,TNF-α contents in brain tissue were decreased,gene expressions of ZO-1 and Claudin-1 in colon tissue were increased significantly(P<0.05);LPS and D-LA contents in serum were decreased in YH-HJP medium and high doses groups,while gene expressions of ZO-1 and Claudin-5 in brain tissue were increased significantly(P<0.05).Conclusion:YHHJP has a good effect on improving CIRI,whose mechanism may be related to regulating diversity of intestinal flora,reducing release of intestinal bacterial metabolites LPS and D-LA,increasing gene expressions of tight junction proteins ZO-1,Claudin-5 and Claudin-1,and down-regulating secretion of proinflammatory cytokine.

The secondary motor cortex (M2) encodes choice-related information and plays an important role in cue-guided actions. M2 neurons innervate the dorsal striatum (DS), which also contributes to decision-making behavior, yet how M2 modulates signals in the DS to influence perceptual decision-making is unclear. Using mice performing a visual Go/No-Go task, we showed that inactivating M2 projections to the DS impaired performance by increasing the false alarm (FA) rate to the reward-irrelevant No-Go stimulus. The choice signal of M2 neurons correlated with behavioral performance, and the inactivation of M2 neurons projecting to the DS reduced the choice signal in the DS. By measuring and manipulating the responses of direct or indirect pathway striatal neurons defined by M2 inputs, we found that the indirect pathway neurons exhibited a shorter response latency to the No-Go stimulus, and inactivating their early responses increased the FA rate. These results demonstrate that the M2-to-DS pathway is crucial for suppressing inappropriate responses in perceptual decision behavior.

Glioblastoma (GBM) is the most common and aggressive malignant brain tumor in adults and is poorly controlled. Previous studies have shown that both macrophages and angiogenesis play significant roles in GBM progression, and co-targeting of CSF1R and VEGFR is likely to be an effective strategy for GBM treatment. Therefore, this study developed a novel and selective inhibitor of CSF1R and VEGFR, SYHA1813, possessing potent antitumor activity against GBM. SYHA1813 inhibited VEGFR and CSF1R kinase activities with high potency and selectivity and thus blocked the cell viability of HUVECs and macrophages and exhibited anti-angiogenetic effects both in vitro and in vivo. SYHA1813 also displayed potent in vivo antitumor activity against GBM in immune-competent and immune-deficient mouse models, including temozolomide (TMZ) insensitive tumors. Notably, SYHA1813 could penetrate the blood-brain barrier (BBB) and prolong the survival time of mice bearing intracranial GBM xenografts. Moreover, SYHA1813 treatment resulted in a synergistic antitumor efficacy in combination with the PD-1 antibody. As a clinical proof of concept, SYHA1813 achieved confirmed responses in patients with recurrent GBM in an ongoing first-in-human phase I trial. The data of this study support the rationale for an ongoing phase I clinical study (ChiCTR2100045380).

This study critically examines the current status of interoception research in modern psychology， taking into account perspective of traditional Chinese medicine （TCM）， encompassing both foundational studies and clinical applications. The investigation highlights a deep interconnection between psychosomatic theories in TCM， such as the TCM emotions and viscera theory and the view of body-spirit syncretism， and the concept of interoception at the cognitive level. Moreover， philosophical principles， particularly the “Zhi Yi Lun” in TCM， align naturally with the three-dimensional interoception model. Importantly， this comparative analysis emphasizes that Western and Chinese medicine place different emphasis on interoception research with the former focusing on diagnosis and the latter on treatment. These differing approaches complement each other and provide opportunities for cross-fertilization. At the practical level of interoception application， “five-state personality classification” demonstrates promising potential for further clinical application. In addition， TCM has valuable insights for contemporary medical practices in terms of emotional regulation. TCM methods for emotional regulation， known as “Daoyin”， provide important knowledge in this area. One concept developed by TCM for clinical intervention targeting interoception is “Tiao Qi” （regulating qi）. This concept is used during diagnosis and treatment in TCM and plays a crucial role in managing interoceptive states. This paper aims to explain the cognitive and applied aspects of interoception in TCM， offering a perspective for future research and clinical application. By integrating modern psychology's psychosomatic medicine model， TCM can enhance its relevance and efficacy in contemporary medical contexts. This integration promotes a balanced relationship between the mind and body. TCM researchers have a responsibility to explore the inherent strengths and practical value of TCM in interoception research， and contribute to the advancement of TCM.

Objective:To analyze the clinical features of bronchiectasis in children after severe adenovirus pneumonia and to provide clinical clues for the early diagnosis of bronchiectasis in children after severe adenovirus pneumonia.Methods:A retrospective study was made to analyze the clinical data of 26 children with bronchiectasis after severe adenovirus pneumonia treated in Guangzhou Women and Children′s Medical Center, Guangzhou Medical University from May 2016 to May 2021.Results:A total of 26 cases were reported, including 18 males and 8 females.The median onset age of severe adenovirus pneumonia was 23.0 (15.0, 48.0) months.A total of 23 cases suffered concurrent infections, and bacterial co-infection was the most common (16 cases). High resolution computed tomography (HRCT) showed multiple lobar solids in the lung with/without pleural effusion.During the acute phase, most of the cases were treated with intravenous immunoglobulin (21 cases), mechanical ventilation (20 cases), and systemic glucocorticoids (19 cases). The median age at diagnosis of bronchiectasis was 29.5 (21.0, 56.8) months, and the median time that the patients took to develop into acute adenovirus pneumonia was 6.0 (3.3, 13.0) months.Six cases suffered bronchiectasis alone, and 20 cases had bronchiectasis combined with post-infectious bronchiolitis obliterans (PIBO). Of these 20 cases, 3 cases developed bronchiectasis and PIBO simultaneously, and the remaining 17 cases developed bronchiectasis after PIBO.In the included 26 cases, diffuse bronchiectasis predominated (24 cases), most frequently involving the left lower lobes (21 cases) and right lower lobes (21 cases). Cylindrical bronchiectasis was the most common type (23 cases). All the patients had recurrent cough and wheezing during follow-up, and only 3 cases coughed up pus sputum without hemoptysis.All children had acute exacerbations, which were mostly caused by bacteria (21 cases). Nineteen cases combined with PIBO and 1 case with only bronchiectasis were rehospitalized.There was no cases of surgical resection or death.Conclusions:Bronchiectasis after severe adenovirus pneumonia mostly occurs in patients with or without PIBO.Multiple lobe involvement and co-infection may be a risk factor for PIBO patients to develop bronchiectasis.The clinical manifestations are mostly recurrent cough and wheezing, while sputum and hemoptysis are less common.Pediatricians should promptly perform chest HRCT for early diagnosis of the disease.

Objective:To determine the effects of menopausal stage, age and other associated risk factors on symptoms of anxiety and depression among women in a community in Beijing.Methods:This study was a community-based prospective cohort. Participants who had transitioned through natural menopause, completed two or more depressive and anxiety symptoms evaluations, aged 35 to 64 years, and did not use hormone therapy were selected from the Peking Union Medical College Hospital aging longitudinal cohort of women in midlife to this analysis. The primary outcome variables were depressive and anxiety symptoms, assessed by hospital anxiety and depression scale (HADS). The generalized estimation equation was used in the statistical analysis.Results:Followed up from 2006 to 2014, 430 women and 2 533 HADS assessments were retained in the cohort. Depressive symptoms were more common than anxiety symptoms during all menopausal stages. The incidences of depressive and anxiety symptoms were 14.5% (19/191) and 3.1% (4/191) in the premenopausal -3 stage, respectively. The incidence increased in both menopausal transition and postmenopausal stage, with the highest incidence in the +1c stage [20.6% (155/751) and 8.8% (66/751), respectively]. However, these differences were not statistically significant (all P>0.05). Depressive symptoms were highest in the ≥60-<65 age group [20.8% (74/355)], and anxiety symptoms were highest in the ≥50-<55 age group [8.2% (62/754)]; but there were no statistical significances between different age groups and depressive and anxiety symptoms (all P>0.05). Multivariable analysis showed that high body mass index, low education status, and poor health status were independently associated with depressive symptoms (all P<0.05), and that poor health status, trouble falling asleep, and early awakening were independently associated with anxiety symptoms (all P<0.01). Conclusions:Depressive and anxiety symptoms are more common during menopausal transition and postmenopausal stage compared with reproductive stage. Depressive symptoms are more common than anxiety symptoms. To screen and assess depressive and anxiety symptoms in perimenopausal women is essential, especially for women with high risk factors.

Objective:To investigate the diagnosis and treatment of multicentric Castleman disease (MCD).Methods:The diagnosis and treatment of one MCD patient admitted in Hangzhou First People's Hospital in July 2020 was analyzed and related literatures were reviewed.Results:The patient was a 55-year-old male with anemia, elevated globulin levels and IgG4 > 10 g/L, and enlarged lymph nodes. He was undiagnosed for 7 years. Lymph node biopsy revealed a large number of polyclonal plasma cell hyperplasia, and the ratio of IgG4/IgG was less than 0.40; the serum interleukin (IL)-6 was more than 6 000 pg/ml and then he was eventually diagnosed as MCD (plasma cell type). Rituximab + cyclophosphamide + dexamethasone (RCD) regimen was not effective, and it was changed to anti-IL-6 receptor antibody tocilizumab for 2 courses and then the patient obtained good results.Conclusions:Castleman disease is a rare disease with a poor prognosis. It has high heterogeneity and is easy to be misdiagnosed clinically. The diagnosis requires pathological examination. IL-6 is considered to be closely related to the onset of Castleman disease and has become an effective target for treatment.
