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.

ObjectiveTo investigate the effects of Buzhong Yiqitang on the abnormal expression of pulmonary surfactant-associated protein C （SFTPC） and lung injury induced by chronic intermittent hypoxia （CIH） and the mechanism of action. MethodsForty healthy adult male SPF-grade C57BL/6 mice were randomly allocated into five experimental groups： a normoxia group， a CIH group， and low-， medium-， and high-dose Buzhong Yiqitang groups， with eight mice in each group. During the modeling， mice in the normoxia group were housed under standard oxygen concentrations， while the CIH and all Buzhong Yiqitang groups were placed in a hypoxic chamber for 8 h daily over 35 d. Prior to each chamber session， mice in the low-， medium-， and high-dose Buzhong Yiqitang groups were administered decoctions by gavage at corresponding doses （8.1， 16.2， 32.4 g·kg^-1·d^-1 of crude drug， respectively）， while those in normoxia and CIH groups received an equivalent volume of saline by gavage. The general conditions of the mice were recorded before and after the experiment. Pulmonary function was assessed using a non-invasive detection system. Serum SFTPC levels were measured using enzyme-linked immunosorbent assay （ELISA）. Histopathological changes in lung tissue were evaluated using hematoxylin-eosin （HE） staining. Apoptosis in lung tissue was detected using terminal deoxynucleotidyl transferase dUTP nick end labeling （TUNEL）. Protein expression of SFTPC， B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， protein kinase R-like endoplasmic reticulum kinase （PERK）， phosphorylated PERK （p-PERK）， eukaryotic initiation factor 2α （eIF2α）， phosphorylated eIF2α （p-eIF2α）， activating transcript factor 4 （ATF4）， and CCAAT/enhancer-binding protein homologous protein （CHOP） in lung tissue was analyzed by Western blot. Immunofluorescence staining was employed to assess the expression of SFTPC and CHOP proteins in lung tissue. ResultsCompared to those in the normoxia group， mice in the CIH group showed significantly impaired pulmonary function and increased histopathological lung injury scores （P<0.05， P<0.01）. Serum SFTPC levels increased， while SFTPC expression in lung tissue was reduced （P<0.05， P<0.01）. The rate of apoptotic cells in lung tissue increased， and the expression of endoplasmic reticulum stress markers p-PERK， p-eIF2α， ATF4， and CHOP was upregulated （P<0.05， P<0.01）. Compared with the CIH group， Buzhong Yiqitang intervention improved pulmonary function indicators and decreased the histopathological lung injury scores （P<0.05， P<0.01）. Serum SFTPC levels were decreased， and lung tissue SFTPC expression was recovered （P<0.05， P<0.01）. The apoptotic rate of lung tissue cells was significantly reduced， with downregulation of pro-apoptotic Bax and upregulation of anti-apoptotic Bcl-2 expression （P<0.05， P<0.01）. Activation and expression of p-PERK， p-eIF2α， ATF4， and CHOP were also decreased （P<0.05， P<0.01）. ConclusionBuzhong Yiqitang can alleviate lung injury and improve pulmonary function by reducing lung cell apoptosis and enhancing alveolar surfactant secretion， which may be related to the modulation of the PERK/eIF2α/ATF4/CHOP signaling pathway.

Epilepsy, which leads to an enduring high tendency to generate epileptic seizures, is a neurological disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to abnormal synchronous neuronal discharges. Patients with epilepsy are usually comorbid with various sleep disorders, such as restless leg syndrome/periodic limb movement disorder (RLS/PLMD), chronic insomnia and narcolepsy. Frequent seizures may increase the risk of suffering from sleep disorders; conversely, poor control of sleep disorders exacerbates epilepsy. This review discusses common types of sleep disorders in patients with epilepsy, reveals potential mechanisms, and introduces new advances in the treatment of comorbidity between epilepsy and sleep disorders. The aim is to provide an overview of the close interactions between epilepsy and sleep disorders, providing new ideas and experiences for more effective treatment of sleep disorders and improving the prognosis of patients with epilepsy.

Objective To explore the correlation of MET status in patients with advanced prostatic acinar adenocarcinoma with the clinical pathological parameters and prognosis. Methods The specimen from 135 patients with advanced prostatic acinar adenocarcinoma was included. The expression of c-MET protein was detected via immunohistochemistry, and MET gene amplification was assessed by fluorescence in situ hybridization. The relationships of c-MET expression and gene amplification with clinicopathological features and prognosis were analyzed. Results The positive expression rate of c-MET was 52.60% (71/135). Compared with the c-MET expression in adjacent tissues, that in tumor tissues showed lower heterogeneous expression. Among the cases, 1.71% (2/117) exhibited MET gene polyploidy, but no gene amplification was detected. Positive c-MET expression was significantly correlated with high Gleason scores and grade groups (P=0.0073). However, no significant relationship was found between c-MET expression and progression-free survival or post-treatment t-PSA levels. Conclusion c-MET protein is expressed at a relatively low level in advanced prostatic acinar adenocarcinoma, suggesting that c-MET may not be a viable target for ADC drug development in prostatic acinar adenocarcinoma.

【Objective】 To explore the risk factors for the production of anti-HLA antibodies in patients with hematological diseases before hematopoietic stemcell transplantation. 【Methods】 The results and clinical data of 1 008 patients with hematological diseases in our hospital who underwent anti-HLA antibody testing were collected by using Luminex technology platform before transplantation from 2016 to 2018 for statistical analysis. 【Results】 The total positive rate of anti-HLA antibodies in 1 008 patients was 24.08%. Multivariate analysis showed that independent risk factors associated with the production of anti-HLA antibodies included age≥30 years old(P=0.046, OR1.467, 95%CI1.007-2.136), time from disease diagnosis to antibody testing≥41 days(P=0.000, OR1.830, 95%CI1.306-2.565), initial platelet count<20×10⁹/L(P=0.020, OR1.543, 95%CI1.072-2.220), prior pregnancy(P=0.000, OR5.187, 95%CI3.689-7.293), transfusions before admission(P=0.001, OR1.762, 95%CI1.257-2.470)and total platelet transfusion volumes after admission≥30 U(P=0.000, OR2.352, 95%CI1.638-3.376). Age ≥30 years old(P=0.023, OR=1.839, 95%CI1.088-3.108)and prior pregnancy(P=0.042, OR=5.258, 95%CI1.062-26.038)are associated with the production of anti-HLA class Ⅰ and class Ⅱ antibodies, respectively. The time from disease diagnosis to antibody testing≥41 days(P=0.000, OR=2.873, 95%CI1.612-5.119), initial platelet count<20×10⁹/L(P=0.008, OR=2.164, 95%CI1.225-3.822), prior pregnancy(P=0.002, OR=6.734, 95%CI1.993-22.751), transfusions before admission(P=0.001, OR=2.746, 95%CI1.531-4.925)and total platelet transfusion volumes after admission>30 U(P=0.006, OR=3.459, 95%CI1.416-8.451)are associated with the production of anti-HLA class Ⅰ and Ⅱ antibodies. 【Conclusion】 Older age, longer course of disease, lower PLT count, history of pregnancy and blood transfusion, and higher total amount of PLT transfusion are risk factors which affect the production of anti-HLA antibodies.Therefore, it is advisable to test for anti-HLA antibodies according to the situation before transplantation, which is of great value in guiding donor selection, monitoring antibody changes and improving transplant prognosis.

OBJECTIVE To compare the chemical components contained in Artemisiae Scopariae Herba （ASH） standard decoction and its decoction pieces， and provide foundation of their pharmacological substances. METHODS ASH standard decoction and its decoction pieces were prepared； UFLC-Q-TOF-MS/MS method was used for the detection in the negative ion mode， and the total ion chromatogram was extracted by the PeakView 1.6 software. By comparing with reference substances， literature data， and online search of compound database such as PubChem， the chemical components contained in ASH standard decoction and its decoction pieces were identified and analyzed for the differences. RESULTS A total of 125 chemical components were identified in ASH standard decoction and its decoction pieces， including 50 organic acids， 39 flavonoids， 3 coumarins， 2 amino acids， 5 lignans， and 26 others. 3-methoxy-caffeic acid-4-O- β -D-glucoside， p-hydroxybenzoic acid， caffeic acid 4-O- glucoside， spiraeoside， and phenyl β-D-glucoside in ASH standard decoction were not detected in its decoction pieces， while 6′-6′ chlorogenic acid dimer， quercetin-5-glucoside， apigenin 7-methyl ether 5-（6″-malonylglucoside）， quercetin-3-O-arabinoside， 6″-caffeoylhyperin and 6-O-caffeoyl-D-glucoside in decoction pieces were not detected in the standard decoction. CONCLUSIONS Most components in ASH decoction pieces are transferred to its standard decoction， but a few components undergo chemical reactions in whole or in part during the boiling process， transforming into other or new components in the standard decoction.

Objective To investigate the dyadic coping experience of patients undergoing cancer surgery and their spouses.Methods Sixteen cancer patients who were initially diagnosed with cancer and underwent cancer surgery in a general hospital in Henan province as well as and their spouses were selected as the study subjects by objective sampling method.All the patients and their spouses were included in the postoperative follow-up for dyadic coping experiences though a 3 months interview.The acquired data were summarised and analysed by Colaizzi's phenomenological method to identify relevant themes.Results A total of eight themes were identified,including three themes over the phase of confirmed diagnosis,strong stress response,coping with stress alone and consistent attitude towards seeking medical treatment;two themes over the perioperative phase,lack of coping ability and change in relationship;and three themes over the phase of home recovery,lack of disease information,poor communication skills and post-trauma growth of both patient and spouse.Conclusions The dyadic coping experience of patients who undergo cancer surgery and their spouses varies with the stages across the treatment.Therefore,medical staff should offer targeted nursing care according to the dyadic coping experience at different stages,hence to improve the physical and mental health of the cancer patients and their spouses.

Objective To study the brain functional connectivity(FC)changes in patients with normal tension glau-coma(NTG)and healthy volunteers using FC technique of resting-state functional magnetic resonance imaging(rs-fMRI)based on V1 region seed point(ROI),so as to explore the pathogenesis and early diagnosis of NTG.Methods Fourteen NTG patients(NTG group)who met the inclusion criteria and 14 healthy controls(HCs group)were enrolled.The clinical data of all subjects were collected,and rs-fMRI was performed in both groups.The magnetic resonance data was pre-pro-cessed by software,and bilateral A1 regions were taken as the ROI to analyze their correction with the whole brain voxel time series and obtain the FC value between the ROI and the whole brain by comparison of FC values in resting state be-tween the groups.Pearson correlation analysis was used to explore the relationship between FC value in the brain regions with significant differences with the ROI and clinical variables in the NTG group.Results Compared with the subjects in the HCs group,there were no statistically significant differences in age,gender,body weight,cup-disc ratio and 24 h mean intraocular pressure of patients in the NTG group(all P＞0.05),and there were statistically significant differences in the best corrected visual acuity(BCVA)of both eyes and peripapillary retinal nerve fiber layer thickness(RNFLT)(all P＜0.05).The Pearson correlation analysis showed that FC value of the brain regions with abnormal FC to V1 region were cor-related with RNFLT in the NTG group(P＜0.05).ROI1-left superior frontal gyrus,ROI1-right superior frontal gyrus,ROI2-left cingulate gyrus and ROI2-right middle frontal gyrus were significantly positively correlated with RNFLT(all P＜0.05).Compared with the HCs group,the brain regions with reduced FC to the right ROI in the NTG group were the left superior frontal gyrus and right superior frontal gyrus;the brain regions with reduced FC to the left ROI were the left cingulate gyrus and right middle frontal gyrus.Conclusion Compared to healthy individuals,NTG patients have significant changes in the functional connections between certain specific brain regions and V1 region,including bilateral superior frontal gyrus,left cingulate gyrus,and middle frontal gyrus.The changes in brain functional activity may be caused by visual dysfunction caused by NTG,leading to functional impairment of the visual and cognitive emotion processing brain regions,which may be one of the potential neuropathological mechanisms in NTG patients.

Objective To explore the changes in macular microcirculation status and visual function in patients with normal tension glaucoma(NTG)using the optical coherence tomography angiography(OCTA)and microperimeter MP-3 and analyze the correlation between the two.Methods In this cross-sectional observational study,17 NTG patients(30 eyes)were collected as the NTG group and then divided into mild,moderate and severe NTG subgroups according to the severity of the disease.During the same period,13 healthy subjects(23 eyes)with the same age and gender distribution were selected as the control group.OCTA was used to obtain linear density(LD)and perfusion density(PD)of superficial retinal vessels in the macular area.The microperimeter MP-3 was used to measure retinal sensitivity(RS)within 10° and fixation rate at 2° and 4° of the macular area.The OCTA parameters and microperimeter MP-3 parameters were compared among all groups,and the correlation between OCTA parameters and microperimeter MP-3 parameters in NTG patients was analyzed.Results There were no significant differences in LD and PD between the control group and the mild NTG sub-group in the central and nasal sides of the macula;the LD and PD in the remaining regions and overall average LD and PD showed a gradual downward trend in the control group and the mild,moderate and severe NTG subgroups.Compared with the control group,the RS of the mild NTG subgroup was lower in the inferior and temporal regions of the macular area.The RS of each region and overall average RS in the macular area decreased with the aggravation of the NTG.In the NTG group,LD and PD were significantly positively correlated with RS in each region and overall average RS in the macular area(all P＜0.05).In the NTG group,LD and PD were positively correlated with P2 in some regions of the macular area.Con-clusion Compared with the control group,the macular microcirculation status and visual function of NTG patients signif-icantly decreased with the progression of the disease;there is a significant correlation between macular LD and RS in NTG patients.

[Objective] To analyze the influencing factors of postoperative patency of longitudinal single suture intussusception microsurgical vasoepididymostomy, to provide reference for improving the repetition rate. [Methods] The clinical data of 82 patients with epididymal obstructive azoospermia who underwent longitudinal single suture intussusception microsurgical vasoepididymostomy in our hospital during Sep.2020 and Jan.2023 were retrospectively analyzed.The postoperative patency and spouse pregnancy were followed up by face to face and / or telephone interview.The effects of age, course of disease, body mass index (BMI), previous medical history (epididymitis, operation history, none), preoperative seminal plasma elastase (SPE) level, anastomosis site, unilateral and bilateral lesion, sperm quality, operation time and hospital stay on the postoperative patency rate were analyzed. [Results] All operations were successful, the follow-up rate was 95.12% (78/82), 78 were married, and the postoperative patency was 78.21% (61/78). Of the 61 patients who achieved patency, 56 were married, and the natural pregnancy rate of spouse was 45.21% (33/73). Univariate analysis showed that patients with age <30 years, course of disease <2 years, preoperative SPE level <290 ng/mL, bilateral anastomosis, body or tail anastomosis and motile sperm had higher postoperative patency rate (P>0.05). BMI, previous history, the number of motile sperms examined by epididymal fluid, the length of operation and hospital stay had no significant effects on postoperative patency (P>0.05). The results of multivariate logistic regression analysis showed that preoperative SPE level (OR=0.998, 95%CI: 0.997-1.000, P=0.008) and (OR=10.724, 95%CI: 2.243-51.283, P=0.003) were significantly correlated with postoperative patency. [Conclusion] The preoperative SPE level and anastomosis site are significant influencing factors of postoperative patency, which is higher in patients with age <30 years, course of disease <2 years, preoperative SPE level <290 ng/mL, bilateral anastomosis, body or tail anastomosis and motile sperm.
