The etiology of tumors is complex and influenced by multiple factors, including the host and environmental conditions. Allergy is primarily driven by the immune response of helper T cell 2 (Th2). Research has shown that the Th2 immune response is closely related to tumors, which is specifically manifested through Th2 antibodies, allergy-related effector cells and mediators within the tumors, as well as tumor immune-related functions. This internal interaction mechanism will increase the complexity and challenges associated with the clinical diagnosis and treatment of tumors and allergy. The formation of allergic constitution is shaped by both congenital and acquired factors, and its physical state is closely linked to the occurrence and progression of allergic diseases. Therefore, this paper aims to explore the relationship between tumors and allergic reactions from the perspective of traditional Chinese medicine (TCM) constitution theory. Based on the four basic principles of the TCM constitution, including endowment inheritance theory, environment constraint theory, body-spirit composition theory, and life process theory, this exploration will focus on four aspects: genetic factors and internal disease causes, inflammatory environments and functional regulation, psychological disorders and emotional pathogenesis, as well as age structure and disease risk. Furthermore, from the perspective of constitution-disease relation of chronic disease prevention, this paper will discuss the significant importance of adjusting allergic constitution to improve both subjective symptoms and objective indicators of allergic reactions in tumor patients.

The search covered publications up to December 17, 2022. Two researchers trained in evidence-based nursing independently completed the quality assessment, evidence extraction, and summary of the included literature.Results:A total of 16 publications were included, comprising two clinical decisions, one evidence summary, five guidelines, six systematic reviews, and two randomized controlled studies. The best evidence was summarized from seven aspects: multidisciplinary collaboration, identification of risk factors, assessment and monitoring, referral, psychological behavioral interventions, exercise management, and complementary therapies, resulting in 25 key recommendations.Conclusions:This study summarizes the current best evidence for non-pharmacological management of sleep disorders in breast cancer patients undergoing chemotherapy. Healthcare professionals can follow these best evidence practices to standardize the assessment of patient sleep disorder symptoms and choose appropriate intervention plans based on clinical context and patient preferences, thereby improving patient sleep quality.

BACKGROUND: Limited data are available on the comparison of clinical outcomes of complete vs. incomplete percutaneous coronary intervention (PCI) for patients with chronic total occlusion (CTO) and multi-vessel disease (MVD). The study aimed to compare their clinical outcomes. METHODS: A total of 558 patients with CTO and MVD were divided into the optimal medical treatment (OMT) group ( n = 86), incomplete PCI group ( n = 327), and complete PCI group ( n = 145). Propensity score matching (PSM) was performed between the complete and incomplete PCI groups as sensitivity analysis. The primary outcome was defined as the occurrence of major adverse cardiovascular events (MACEs), and unstable angina was defined as the secondary outcome. RESULTS: At a median follow-up of 21 months, there were statistical differences among the OMT, incomplete PCI, and complete PCI groups in the rates of MACEs (43.0% [37/86] vs. 30.6% [100/327] vs. 20.0% [29/145], respectively, P = 0.016) and unstable angina (24.4% [21/86] vs. 19.3% [63/327] vs. 10.3% [15/145], respectively, P = 0.010). Complete PCI was associated with lower MACE compared with OMT (adjusted hazard ratio [HR] = 2.00; 95% confidence interval [CI] = 1.23-3.27; P = 0.005) or incomplete PCI (adjusted HR = 1.58; 95% CI = 1.04-2.39; P = 0.031). Sensitivity analysis of PSM showed similar results to the above on the rates of MACEs between complete PCI and incomplete PCI groups (20.5% [25/122] vs. 32.6% [62/190], respectively; adjusted HR = 0.55; 95% CI = 0.32-0.96; P = 0.035) and unstable angina (10.7% [13/122] vs. 20.5% [39/190], respectively; adjusted HR = 0.48; 95% CI = 0.24-0.99; P = 0.046). CONCLUSIONS For treatment of CTO and MVD, complete PCI reduced the long-term risk of MACEs and unstable angina, as compared with incomplete PCI and OMT. Complete PCI in both CTO and non-CTO lesions can potentially improve the prognosis of patients with CTO and MVD.

The stem and branch extract of Tripterygium wilfordii (Celastraceae) afforded seven new dihydroagarofuran sesquiterpene polyesters [tripterysines A-G (1-7)] and eight known ones (8-15). The chemical structures of these new compounds were established based on combinational analysis of HR-ESI-MS and NMR techniques. The absolute configurations of tripterysines A-C (1-3) and E-G (5-7) were determined by X-ray crystallographic analysis and circular dichroism spectra. All the compounds were screened for their inhibitory effect on inflammation through determining their inhibitory effect on nitric oxide production in LPS-induced RAW 264.7 cells and the secretion of inflammatory cytokines TNF-α and IL-6 in LPS-induced BV2 macrophages. Compound 9 exhibited significant inhibitory activity on NO production with an IC₅₀ value of 8.77 μmol·L^-1. Moreover, compound 7 showed the strongest inhibitory effect with the secretion of IL-6 at 27.36%.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

The status of lymph node metastasis is an important prognostic factor for many malignant tumors, including lung cancer. In the 8th edition of the TNM staging system for lung cancer, the T staging had obvious changes and refinements, but the N staging had little changes. Recently, several studies have found that the prognosis of patients with the same N stage can vary greatly, suggesting that a more detailed subgroup of patients with the same N stage should be subdivided, including the inclusion of extra-capsular lymph node metastases (ENE). In this review, we reviewed the definition, classification/grading, imaging diagnosis, pathological diagnosis, related molecular markers and their relationship with the prognosis of lung cancer patients.

Objective:To study the distribution of the literature and the trend of international research of proliferative vitreoretinopathy (PVR) in 10 years from 2009 to 2018.Methods:Using Web of Science database of the American Institute of Scientific Information as the data source to collect literature on proliferative vitreoretinopathy published from 2009 to 2018 and a statistical analysis on the distribution of the publication time, nation and funding agency was made to figure out the institution, periodical, author with highest citations respectively among the collected literature.Meanwhile, the bibliometric analysis software Citespace and VOSviewer were employed to carry out the distribution analysis and cluster analysis of keywords as well as the co-citation cluster analysis.Results:A total of 905 articles related to PVR were included, mainly in English, most of which were written by American authors, and the number of literature published by Chinese authors was ranked the second.Among all the article funding institutions, the National Natural Science Foundation of China ranked NO.1 with the most funded articles.Citations increased year by year since 2009 and increased obviously since 2013.The journal with the highest citations was Investigative Ophthalmology & Visual Science, and the research institution with the highest citations was Harvard University.The statistical analysis of the citation quantity also showed that the top five authors with the highest citations were all from Massachusetts Eye and Ear, Department of Ophthalmology, Harvard Medical School.The results of cluster analysis showed that there were 41 high-frequency subject terms, and they were mainly grouped in 4 categories, which were etiology, risk factors, molecular mechanism, treatment and management of PVR.Keywords network visualization and overlay visualization both showed that etiology and risk factors were the focus of current research, while epithelial mesenchymal transition, transforming growth factor-β and fibrosis were new research fields in recent years.The results of citation cluster analysis showed there were 12 co-citation clusters. Conclusions:The literature of PVR shows an upward trend, and the researches focus on the molecular mechanism, prevention, and neuroprotection of PVR, which may be the future PVR research direction.

In recent years, the subthreshold micropulse laser is a kind of laser mode which is characterized by long intermittence. It achieves effective therapeutic effect while minimizes the damage to tissues. At present, it has been used to treat diabetic macular edema. Early studies suggested that the laser selectively acts on retinal pigment epithelial cells to reduce macular edema by regulating the expression of inflammatory biomarkers, growth factors, heat shock proteins and other substances. In recent years, with the development of research, more and more emphasis has been placed on the role of retinal glial cells. Müller cells are also considered as one of the target cells affected by micropulse laser, but there is no evidence of direct or indirect effects of micropulse laser on Müller cells. In the near future, it is expected that we will have more clinical evidence to confirm the target cells of the micropulse laser, which may be further confirmed by in vitro experiments through Müller cells or Müller cells co-cultured with retina pigment epithelium cells, so as to make a more detailed statement on the mechanism of it.

Objective To analyze the clinical features and prognosis of adult optic neuritis patients with positive serum myelin oligodendrocyte glycoprotein antibody (MOG-ON) or aquaporin 4 antibody (AQP4-ON).Methods A retrospective study. From December 2015 to February 2018, in the Beijing Chaoyang Hospital of Capital Medical University and Chinese PLA General Hospital, 162 eyes of 132 patients with positive serum MOG antibody and AQP4 were included in the study. There were 42 MOG-ON patients (49 eyes, 31.8％), 90 AQP4-ON patients (113 eyes, 68.2％). The clinical features of optic neuritis (annual recurrence frequency, incidence of optic disc edema), brain and optic nerve enhanced MRI, serum autoimmune antibodies and cerebrospinal fluid test results were compared between MOG-ON and AQP4-ON patients. All patients were treated with intravenous methylprednisolone sodium succinate in the acute phase and then switched to oral prednisone acetate tablets. The average follow-up time was 15 months. The glucocorticoid dependence, visual prognosis, spinal cord symptoms, and myelitis at the last follow-up were comparatively analyzed between MOG-ON and AQP4-ON patients. The comparison of the count data was performed by χ2 test, and the measurement data were compared byt test.Results Compared with AQP4-ON patients, MOG-ON patients had higher annual recurrence frequency (t=3.760,P=0.005), higher incidence of optic disc edema (χ2=14.777,P<0.001), higher incidence of hormone dependence (χ2=25.496,P<0.001), and better visual prognosis (χ2=28.759, P<0.001). MOG-ON patients were more likely to involve the optic nerve, AQP4-ON patients were more likely to involve the optic chiasm and the optic tract. There was a significant difference in the location of lesions between MOG-ON and AQP4-ON patients (χ2= 5.447,P= 0.015). The proportion of AQP4-ON patients with autoimmune antibodies was significantly higher than that of MOG-ON patients (χ2 = 20.453,P<0.001). The results of cerebrospinal fluid test showed that the white blood cell count of patients with MOG-ON and AQP4-ON were within the normal range, but the IgG level of AQP4-ON patients was significantly higher than that of MOG-ON patients (t=8.669,P<0.001). At the last follow-up, there were 7 and 29 patients of myelitis in MOG-ON and AQP4-ON patients respectively (χ2=3.494,P=0.046).Conclusions The clinical characteristics of MOG-ON were different from AQP4-ON. The incidence of optic disc edema and recurrence rate were higher, but the proportion of autoimmune antibodies was lower. MOG-ON was more likely to show hormone dependence, but the visual prognosis was better. AQP4-ON was easily involved in optic chiasm and optic tract, and the incidence of myelitis was higher.
