Objective:To analyze the clinical characteristics of patients with chronic obstructive pulmonary disease (COPD) complicated by anorexia.Methods:This cross-sectional study included patients registered in the RealDTC study from May 2023 to December 2023. Demographic data, COPD Assessment Test (CAT) score, modified Medical Research Council (mMRC) dyspnea questionnaire score, Clinical COPD Questionnaire (CCQ) score, forced expiratory volume in one second (FEV 1), forced expiratory volume in the first second predicted of percentage (FEV 1%pred), FEV 1/forced vital capacity (FVC), Global Initiative for Chronic Obstructive Lung Disease (GOLD) grade, GOLD group, number of acute exacerbations and hospitalizations in the past year, and score of the Functional Assessment of Anorexia Cachexia Therapy-Anorexia/Cachexia Subscale-12 (FAACT-A/CS-12) were collected. Patients with a FAACT-A/CS-12 score ≤30 were diagnosed as having anorexia. Multivariate logistic regression analysis was used to evaluate the influencing factors of anorexia in COPD patients. Results:A total of 617 COPD patients were included, of whom 109(17.7%) had anorexia. Compared with non-anorexia patients, COPD patients with anorexia had higher age, CAT, mMRC and CCQ scores, and more acute exacerbations and hospitalizations in the past year, while body mass index, FEV 1, FEV 1%pred and FEV 1/FVC were lower (all P<0.05). The proportions of patients with primary education or below, GOLD 3-4 grade and GOLD E group were higher in COPD patients with anorexia (all P<0.05). Logistic regression analysis showed that a CAT score of 10-<20 [odds ratio ( OR)=4.017, 95% confidence interval ( CI): 1.673-59.645], a CAT score of 20-<30 ( OR=9.686, 95% CI: 3.777-24.842), a CAT score of ≥30 ( OR=78.286, 95% CI: 7.654-800.689) and ≥1 hospitalization in the past year ( OR=2.050, 95% CI: 1.292-3.254) were independent risk factors for anorexia in COPD patients (all P<0.05). Conclusions:COPD patients with anorexia have poor lung function, high symptom burden and high risk of acute exacerbation. Clinicians should pay attention to the management of COPD patients with anorexia and take corresponding intervention measures.

Objective The aim of this study was to explore the effects of lumbar lordosis on spinal sagittal balance after Roussouly type Ⅱ spinal lumbar fusion.Methods In the experiment,96 patients undergoing Roussouly type Ⅱ spinal lumbar fusion in Laohekou First Hospital were enrolled as the research objects between January 2022 and December 2023.According to random number table method,they were divided into control group(intraoperative maintaining of the original lumbar lordosis,n=48)and study group(intraoperative increasing of lumbar lordosis by 5°,n=48).The clinical symptoms[numerical rating scale(NRS),Oswestry disability index(ODI)],spinal and pelvic sagittal parameters[pelvic incidence(PI),sacral slope(SS),pelvic tilt(PT),lumbar lordosis(LL),thoracic kyphosis(TK)],rehabilitation status[Japanese Orthopaedic Association(JOA),Berg balance scale(BBS)]and postoperative complications were compared between the two groups.Results The experiment results showed that at 6 months after surgery,scores of NRS and ODI were decreased in both groups,which were lower in study group than control group(P＜0.05).At 6 months after surgery,PI,SS,PT and LL in study group were(48.48±1.62)°,(35.42±5.39)°,(16.75±1.84)°and(39.36±3.72)°,higher than those in control group[(47.51±2.32)°,(28.83±4.46)°,(13.95±1.77)°,(30.78±3.64),P＜0.05],while TK was lower than that in control group[(11.72±1.08)°vs.(14.26±1.23)°,P＜0.05].At 6 months after surgery,scores of JOA and BBS were increased in both groups,which were higher in study group than control group(P＜0.05).There was no significant difference in incidence of postoperative complications between study group and control group(12.50％vs.14.58％,P＞0.05).Conclusion It can be concluded that appropriate increase of lumbar lordosis can significantly improve spinal sagittal balance,promote the remission of clinical symptoms and rehabilitation process in patients after Roussouly type Ⅱ spinal lumbar fusion.

OBJECTIVE To investigate the current status of cleaning and disinfection of digestive endoscopes in vari-ous grades of hospitals of Hubei Province so as to improve the quality of cleaning and disinfection of the digestive endoscopes.METHODS A survey was conducted by the hospital infection management department of Tongji Hos-pital Affiliated to Tongji Medical College,Huazhong University of Science and Technology from Mar.25,2024 to Mar.29,2024.A questionnaire was formulated by brainstorming and literature review.The electronic question-naire was distributed through the"Wenjuanxing"platform.The questionnaire survey aimed to investigate the per-sonnel,training,equipment and facilities,cleaning and disinfection operations,monitoring and recording of the digestive endoscopy centers of the medical institutions in the province.RESULTS Totally 185 medical institutions were finally included,113 of which were tertiary hospitals,and 72 were secondary and lower-grade hospitals.The tertiary hospitals were superior to the secondary and lower-grade hospitals in the quantity of endoscopes,daily di-agnosis and treatment volume of patients,participation in external training(including continuous training,further education,hospital-level training),provision of some facilities and equipment(ultrasonic cleaners,full pipeline perfusion devices,cleaning brushes,high-pressure water guns,transport containers),some cleaning and disinfec-tion operations(changing the cleaning enzyme solution one time for one endoscope,disinfecting the cleaning brush one time after one-time use),implementation of surveillance of cleaning quality and preservation of surveil-lance records(P＜0.05).However,the tertiary hospital were inferior to the secondary and lower-grade hospitals in standardized use of transferring containers(65.49％)and drying time of air guns(57.52％)(P＜0.05).CONCLUSIONS The quality of cleaning and disinfection of the digestive endoscopes remains large room to be im-proved in the medical institutions of Hubei Province.It is necessary for the medical institutions to strengthen the supervision and training of personnel based on the their actual condition,complete the provision of facilities and e-quipment,standardize the cleaning and disinfection operations,and complete the surveillance and recordings.

Chronic urticaria (CU) is a persistent immune-mediated skin disease with an incompletely understood pathogenesis. As the largest micro-ecosystem in the human body, the gut microbiota participates in complex metabolic processes and produces a wide range of metabolites. The gut microbiota-metabolism axis plays a crucial role in the onset and progression of CU. Patients with CU commonly exhibit gut dysbiosis, characterized by a reduction in beneficial bacteria and an increase in opportunistic pathogens, accompanied by alterations in key metabolites. These changes may disrupt the intestinal barrier and modulate the function of immune cells such as mast cells and T cells, thereby triggering or aggravating distal cutaneous inflammation and contributing to CU pathophysiology. Certain bacterial taxa and metabolites hold promise as potential biomarkers for CU diagnosis, therapeutic response, and prognosis, while interventions targeting gut microbiota have demonstrated potential in ameliorating CU symptoms. Elucidating the characteristics and mechanistic roles of gut microbiota and metabolism in CU could provide a theoretical basis for developing novel individualized diagnostic and therapeutic strategies.

The glucagon receptor (GCGR) is a critical target for the treatment of metabolic disorders such as Type 2 Diabetes Mellitus (T2DM) and obesity. Activation of GCGR enhances systemic insulin sensitivity through paracrine stimulation of insulin secretion, presenting a promising avenue for treatment. However, the discovery of effective GCGR agonists remains a challenging and resource-intensive process, often requiring time-consuming wet-lab experiments to synthesize and screen potential compounds. Recent advances in artificial intelligence technologies have demonstrated great potential in accelerating drug discovery by streamlining screening and efficiently predicting bioactivity. In the present work, we propose DeepGCGR, a two-layer deep learning model that leverages graph convolutional networks (GCN) integrated with a multiple attention mechanism to expedite the identification of GCGR agonists. In the first layer, the model predicts the bioactivity of various compounds against GCGR, efficiently filtering large chemical libraries to identify promising candidates. In the second layer, DeepGCGR classifies high bioactive compounds based on their functional effects on GCGR signaling, identifying those with potential agonistic or antagonistic effects. Moreover, DeepGCGR was specifically applied to identify novel GCGR-regulating compounds for the treatment of T2DM from natural products derived from traditional Chinese medicine (TCM). The proposed method will not only offer an effective strategy for discovering GCGR-targeting compounds with functional activation properties but also provide new insights into the development of T2DM therapeutics.

Objective:This study aims to investigate the influence of microvessel density（MVD） and microlymphatic vessel density（MLVD） on the prognosis of patients with hypopharyngeal squamous cell carcinoma（HPSCC） and to develop a nomogram prediction model for prognosis based on pathological characteristics. Methods:A retrospective analysis was conducted on clinicopathological and follow-up data from HPSCC patients who underwent surgical treatment at our institution between June 2010 and June 2020. Immunohistochemical staining was performed on tumor tissues and adjacent normal margin tissues to evaluate MVD and MLVD. The associations among MVD, MLVD, and clinicopathological features were analyzed. Univariate and multivariate Cox regression analyses were conducted to identify independent risk factors affecting overall survival（OS）. Based on these findings, a nomogram model was constructed and its predictive accuracy was assessed using C-index, receiver operating characteristic（ROC） curve, and calibration curve. Results:Both MVD and MLVD were significantly higher in HPSCC tumor tissues compared to normal tissues. Patients in the high MVD and high MLVD groups exhibited significantly lower OS rates than those in the low MVD and low MLVD groups. Multivariate Cox regression analysis revealed that N stage, recurrence, nerve invasion, lymph node capsule invasion, MVD, and MLVD were independent prognostic factors of OS. Based on these factors, a nomogram prognosis model was successfully constructed. The nomograms demonstrated superior performance in terms of C-index, area under the ROC curve, and calibration, outperforming the AJCC TNM staging system. Conclusion:Elevated MVD and MLVD levels are associated with poorer prognosis in HPSCC patients. The nomogram model based on pathological features provides valuable insights for clinical assessment and decision-making.

Panvascular disease is a complex systemic disorder. Research by our team has established "kidney deficiency-vascular impairment" as its core pathogenesis. Consequently, we developed a three-tiered progressive prevention and treatment strategy: early prevention phase: focuses on tonifying the kidney and reducing turbidity; mid-term control phase: focuses on tonifying the kidney and stabilizing plaque; late recovery phase: focuses on tonifying the kidney and unblocking collaterals. This targeted therapeutic protocol effectively alleviates clinical symptoms, improves biochemical markers, enhances treatment efficacy, and achieves comprehensive management throughout the disease course. This article systematically elaborates on the concept of "kidney deficiency-vascular impairment" in panvascular disease, summarizes the mechanisms of kidney-tonifying Chinese herbal medicines, aiming to provide a beneficial reference for the whole-course management of panvascular diseases.
