Cough variant asthma (CVA) is a chronic respiratory disease with cough as its main symptom. The occurrence of CVA is closely related to non-specific airway inflammation, and its pathogenesis involves environmental, genetic, immune, and other factors. In recent years, the advantages of traditional Chinese medicine (TCM) in the treatment of CVA have attracted the attention of experts and scholars in China and abroad, especially its prominent role in regulating immune balance, relieving cough symptoms in CVA patients, and reducing recurrence. T Helper cells 1 (Th1), T helper cells 2 (Th2), T helper cells 17 (Th17), and regulatory T cells (Treg) are derived from CD4+ T cells. Immune imbalance of Th1/Th2 and Th17/Treg is a new hotspot in the pathogenesis of CVA and a potential key target in the treatment of CVA by TCM. Th cell subsets are in dynamic balance under physiological conditions, maintaining respiratory immune homeostasis in which pro-inflammatory cytokines and anti-inflammatory cytokines are balanced. Immature helper T cells (Th0) can be differentiated into Th1, Th2, Th17, Treg, and other cell subsets due to cytokine types in the microenvironment in the stage of CVA maturation. The proliferation of Th2 cells leads to eosinophilic airway inflammation. Excessive differentiation of Th17 cells induces neutrophil airway inflammation. Th1/Th2 and Th17/Treg cells are mutually restricted in number and function, and the immune imbalance of Th1/Th2 and Th17/Treg is easy to aggravate the generation of inflammatory response. Restoring immune balance is particularly important for the airway anti-inflammatory therapy of CVA. In this paper, the imbalance of Th1/Th2 and Th17/Treg and the pathogenesis of CVA were systematically expounded. Meanwhile, the latest research on the regulation of immune imbalance by TCM compound, single TCM, and its effective ingredients in the treatment of CVA was reviewed. It provides ideas and references for revealing the scientific connotation of TCM regulating immune balance therapy of CVA, as well as the development of clinical treatment and basic research of CVA.

Objective:To explore the clinical application pathway of the CT generative adversarial networks (CTGANs) algorithm in mandibular reconstruction surgery, aiming to provide a valuable reference for this procedure.Methods:A clinical exploratory study was conducted, 27 patients who visited the Department of Oral and Maxillofacial Surgery, Xiangya Hospital of Central South University between January 2022 and January 2024 and required mandibular reconstruction were selected. The cohort included 16 males and 11 females, with the age of (46.6±11.5) years; among them, 7 cases involved mandibular defects crossing the midline. The CTGANs generator produced 100 images, and the mean squared error (MSE) was calculated for differences between any two generated images. Preoperative cone-beam CT data from 5 patients were used to construct a labeled test database, divided into groups: normal maxilla, normal mandible, diseased mandible, and noise (each group containing 70 cross-sectional images). The CTGANs discriminator was used to evaluate the loss values for each group, and one-way ANOVA and intergroup comparisons were performed. Using the self-developed KuYe multioutcome-option-network generation system (KMG) software, the three-dimensional (3D) completion area of the mandible under cone-beam CT was defined for the 27 patients. The CTGANs algorithm was applied to obtain a reference model for the mandible. Virtual surgery was then performed, utilizing the fibular segment to reconstruct the mandible and design the surgical expectation model. The second-generation combined bone-cutting and prebent reconstruction plate positioning method was used to design and 3D print surgical guides, which were subsequently applied in mandibular reconstruction surgery for the 27 patients. Postoperative cone-beam CT was used to compare the morphology of the reconstructed mandible with the surgical expectation model and the mandibular reference model to assess the three-dimensional deviation.Results:The MSE for the CTGANs generator was 2 411.9±833.6 (95% CI: 2 388.7-2 435.1). No significant difference in loss values was found between the normal mandible and diseased mandible groups ( P>0.05), while both groups demonstrated significantly lower loss values than the maxilla and noise groups ( P<0.001). All 27 patients successfully obtained mandibular reference models and surgical expectation models. In total, 14 162 negative deviation points and 15 346 positive deviation points were observed when comparing the reconstructed mandible morphology with the surgical expectation model, with mean deviations of -1.32 mm (95% CI:-1.33- -1.31 mm) and 1.90 mm (95% CI: 1.04-1.06 mm), respectively. Conclusions:The CTGANs algorithm is capable of generating diverse mandibular reference models that reflect the natural anatomical characteristics of the mandible and closely match individual patient morphology, thereby facilitating the design of surgical expectation models. This method shows promise for application in patients with mandibular defects crossing the midline.

This paper summarized Professor LI Yueqing's clinical experience in treating prostate cancer by stages from the perspective of deficiency and stasis. It is believed that the onset of prostate cancer is due to kidney deficiency, while blood stasis is the core pathogenesis, and dampness-heat, phlegm-turbid, and cancer toxins are the key pathological factors in the progression of the disease. The pathogenesis in the early stage of the disease is kidney qi depletion and dampness, heat and phlegm coagulation; in the middle stage, it is spleen and kidney depletion, phlegm coagulation and blood stasis; and in the late stage, the pathogenesis changes into yin deficiency and essence depletion, and stasis-turbid toxin obstruction. For treatment, the basic principle is to supplement and boost kidney qi, enrich and nourish the kidney yin. The main treatment methods are draining dampness, dissolving phlegm, dispelling stasis, clearing heat and resolving toxins, and the method of invigorating blood and dispelling stasis runs through the whole course of treatment. In the early stage, radical treatment is mainly used, and Longshe Yangquan Decoction (龙蛇羊泉汤) with modifications is supplemented to clear and drain dampness and heat. In the middle stage, androgen deprivation therapy is the basic treatment, and Bushen Tongqiao Decoction (补肾通窍汤) with modifications is used in combination to nourish the spleen and kidney, dissolve phlegm and dispel stasis. In the late stage, Dabuyin Pills and Liuwei Dihuang Pills (大补阴丸合六味地黄丸) with modifications is mainly used to enrich yin and supplement essence, resolve toxins and dissolve stasis, and prevent cancer recurrence.

Objective:To investigate the influence of maternal autoimmune diseases and anticoagulants, including low-molecular-weight heparin (LMWH) and aspirin, on the fetal fraction of maternal plasma cell-free DNA of non-invasive prenatal testing (NIPT).Methods:A prospective cohort study was conducted on women with singleton pregnancies receiving NIPT in the Nanjing Drum Tower Hospital from March 2021 to July 2022. NIPT was carried out using a polymerase chain reaction (PCR)-free amplification platform. In this study, four types of maternal autoimmune diseases, which were antiphospholipid syndrome, undifferentiated connective tissue disease, Sj?gren's syndrome, and systemic lupus erythematosus (SLE), and two anticoagulants, LMWH and aspirin, were studied. Univariate and multivariate linear regression models were used to analyze the factors influencing fetal fraction of maternal plasma cell-free DNA.Results:A total of 4 102 singleton pregnant women were enrolled in the prospective cohort, and 3 948 were finally included after excluding the cases with unclear dosing time of LMWH or aspirin, other autoimmune diseases, conceiving through ovulation induction alone, and having true positive or failed NIPT result. There were 96 cases with antiphospholipid syndrome, 35 with undifferentiated connective tissue disease, 34 with Sj?gren's syndrome, and 18 with SLE. A total of 108 patients only received LMWH treatment, 121 only received aspirin treatment, and 113 received both LMWH and aspirin treatment. Univariate linear regression analysis showed that maternal body mass index at blood collection ( B=-0.423), conceived by assisted reproductive technology ( B=-0.803), male fetus ( B=-0.458), undifferentiated connective tissue disease ( B=1.774), and SLE ( B=3.467) had influence on the fetal fraction (all P<0.05). Multivariate linear regression analysis showed that maternal body mass index at blood collection ( B=-0.415), conceived by assisted reproductive technology ( B=-0.585), male fetus ( B=-0.322), SLE ( B=3.347) and undifferentiated connective tissue disease ( B=1.336) were factors influencing fetal fraction (all P<0.05). Conclusions:Maternal use of LMWH or aspirin does not affect fetal fraction when performing NIPT on a PCR-free amplification platform, but undifferentiated connective tissue disease and SLE are the influencing factors. Therefore, pregnant women should be informed before the NIPT that the fetal fraction of maternal plasma cell-free DNA may be affected by maternal autoimmune diseases.

ObjectiveTo systematically review the clinical experience of four sessions of Masters of Traditional Chinese Medicine and two sessions of National Famous Chinese Medicine Practitioners in treating ulcerative colitis (UC). Data mining and analysis were conducted to clarify the diagnosis and treatment ideas and characteristics of prescription used by these famous doctors in treating UC. MethodsRelevant literature on the treatment of UC by renowned doctors was retrieved from the establishment of the database until March 31, 2023. The literature was collected from databases such as China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, Chinese Science and Technology Periodicals Database, and China Biomedical Literature Database. The data mining techniques including frequency analysis, association rules, and cluster analysis were conducted using the Ancient and Modern Medical Case Cloud Platform V2.3.5. ResultsA total of 157 literatures were included in this study, including 115 clinical case data. The study found that UC can be categorized into 14 types of syndrome patterns for treatment, including large intestine dampness-heat syndrome (75,65.22%), syndrome of dampness stagnancy due to spleen deficiency (23, 20.00%), spleen-kidney yang deficiency syndrome (21, 18.26%). The main affected organs were the spleen (85, 73.91%) and large intestine (75, 65.22%), and they were closely related to liver (24, 20.87%) and the kidney (21, 18.26%). The predominant pathogenic factors were dampness (83, 72.17%) , heat (80, 69.57%) and qi deficiency (65, 56.52%). The treatment involved 30 kinds of treatment methods, including heat-clearing and dampness-draining method (75, 65.22%), pleen-tonifying and qi-boosting method (25,21.74%) and spleen-invigorating and dampness-transforming method (23, 20.00%). The medication involved 187 ingredients, with the most commonly used being heat-clearing herbs (37, 19.79%) and tonifying herbs (27, 14.44%). The tastes of the herbs were mostly sweet (85, 45.45%) , bitter (80, 42.78%) , and pungent (71, 37.97%). The association rules revealed 16 high-frequency combinations mainly composed of Huanglian (黄连), Baishao (白芍) and Gancao (甘草) along with Baizhu (白术), Fuling (茯苓), Muxiang (木香) and Danggui (当归). ConclusionFamous doctors are skilled in diagnosing and treating UC based on the differentiation of the zang-fu organs and qi-blood. The key pathological mechanism is “spleen deficiency as the root, and large intestine damp-heat as the manifestation”. The core treatment approach is “heat-clearing, spleen-tonifying, and dampness-draining”, with the inclusion of “regulating qi and blood, and balancing cold and heat”.
