ObjectiveTo investigate the effect of Tougu Xiaotong capsules (TGXTC) on the regulation of chondrocyte PANoptosis, delay of chondrocyte degeneration, and improvement of the symptoms in knee osteoarthritis (KOA). MethodsIn vivo experiments: 50 male C57BL/6 mice were randomly assigned into five groups (n=10 per group): sham operation group, model group, low-dose TGXTC group (7.2 g·kg-1), high-dose TGXTC group (14.4 g·kg-1), and diclofenac sodium group (0.05 g·kg-1). Except for the sham group, KOA models were established in all other groups using the modified Hulth method. Following successful model induction, the TGXTC groups received daily oral gavage of 7.2 or 14.4 g·kg-1 for 6 weeks, while the diclofenac sodium group received 0.05 g·kg-1 solution daily over the same duration. Model evaluation was performed using Lequesne MG score; micro-computed tomography (micro-CT) was used to scan the knee, hematoxylin-eosin (HE) staining and safranin O-fast green staining were used to observe the morphology of cartilage, transmission electron microscopy (TEM) was used to determine ultrastructural changes of PANoptosis. Multiple immunofluorescence (IF) co-localization assays was performed to detect the co-localization of cleaved Caspase-3, receptor-interacting protein 3 (RlPK3), and the N-terminal domain of gasdermin D (GSDMD-N) in cartilage tissue, while western blot was employed to detect the expression levels of cleaved Caspase-3, RIPK3, and GSDMD-N. In vitro experiments: The knee cartilages of 4-week-old SD rats were isolated, and a chondrocyte in vitro culture system was established through mechanical digestion with 0.2% type Ⅱ collagenase. Second-generation chondrocytes were divided into three groups: the control group, the model group (pretreated with 10 mg·L-1 lipopolysaccharide (LPS) for 24 h followed by treatment with 1 μmol·L-1 nigericin for 4 h), and the TGXTC treatment group (pretreated with 10 mg·L-1 LPS for 24 h, followed by exposure to 1 μmol·L-1 nigericin for 4 h and subsequently treated with 100 mg·L-1 TGXTC for an additional 24 h). The levels of reactive oxygen species (ROS), apoptosis, necroptosis, and pyroptosis of chondrocytes were evaluated via fluorescence microscopy following staining with ROS detection, AO/EB and YO-PRO-1/PI staining kits. Transmission electron microscopy was utilized to investigate the ultrastructural changes associated with PANoptosis in cartilage tissue of KOA mice. Inflammatory cytokine levels (IL-1β and IL-18) were measured using ELISA. Western blot was conducted to assess protein expressions related to PANoptosis, including cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3. ResultsCompared with the sham group, the Lequesne MG scores were significantly up-regulated(P<0.01) in the model group, and the pathological changes of cartilage were significantly, with joint spaces narrower, osteophyte formation increased, secere abrasion of cartilage surface. Ultrastructural analysis revealed pronounced chondrocyte apoptosis, necroptosis, and pyroptosis, along with markedly elevated expression of cleaved Caspase-3, RlPK3, and GSDMD-N in cartilage tissue (P<0.01). In addition, The mean fluorescence intensities of ROS, orange-red fluorescence in AO/EB staining, green fluorescence and red fluorescence in YO-PRO-1/PI staining were increased of chondrocyte in the model group (P<0.01) . The levels of inflammatory factors IL-1β and IL-18 in the supernatant were increased (P<0.01). The expression of PANoptosis related proteins (cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3) were also significantly upregulated(P<0.05). Compared to the model group, the TGXTC group demonstrated a significant improvement in various parameters of mice. These included a reduction in the Lequesne MG score, an increase in joint space, a decrease in osteophyte formation, diminished cartilage damage, reduced release of ROS, and alleviation of apoptotic, necroptotic, and pyroptotic processes in chondrocytes. Additionally, mitochondrial swelling and endoplasmic reticulum dilation were also mitigated. The levels of ROS as well as IL-1β and IL-18 were significantly decreased (P<0.05). Furthermore, the expression levels of proteins associated with PANoptosis in cartilage tissue showed marked reductions (P<0.05). Similar results were observed in chondrocytes: cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3 exhibited significant decreases as well (P<0.05). ConclusionTGXTC may mitigate chondrocytes degeneration and alleviate KOA symptoms by reducing oxidative stress and suppressing the activation of PANoptosis pathways.

Gastroesophageal reflux disease (GERD) is a frequently and commonly occurring disease in clinic. In recent decades, with the development in pathophysiology and drug researches, modern medicine has achieved remarkable progress and results in diagnosis and treatment. However, the treatments for non-erosive reflux disease, refractory gastroesophageal reflux disease, proton pump inhibitor resistance, overlap of disease symptoms, and extraesophageal symptoms are limited and ineffective. Traditional Chinese medicine (TCM) was widely used in clinical practice, which has been proved effective in relieving symptoms and improving the quality of life. Sponsored by China Association of Chinese Medicine (CACM) and undertaken by the Spleen and Stomach Disease Branch of CACM, "the 12th Youth Salon of Clinical Predominance Disease Series (GERD)" invited 18 authoritative digestive experts of TCM and western medicine to discuss "the difficulties of clinical diagnosis and treatment of GERD and TCM advantages". The focus issues such as modern medical diagnosis and treatment achievements and contributions, improvement and maintenance of symptoms, response to overlapping disease symptoms, reduction and withdrawal of acid suppressors, and treatment of extra-esophageal symptoms were discussed in depth. TCM and western medicine exchanged and complemented each other's strengths, combing the difficulties of modern medical diagnosis and treatment, which clarified the positioning and advantages of TCM and provided guidance for clinical and scientific research.

Objective:To explore the value of bedside chest radiograph in the diagnosis and follow-up of severe and critical COVID-19.Methods:Twenty-nine patients with severe or critical COVID-19 were collected from January 23 to February 23, 2020,from four COVID-19 designated hospitals in Guangdong Province. Bedside radiography was taken in all the 29 patients, ranged from 1 to 16 times for each patient. Twenty-seven patients underwent follow-up, and the number of re-examination ranged 1 to 15 times, and the interval of review is 1 to 8 days.The imaging findings of bedside chest radiography and the imaging changes on follow-up chest radiography were analyzed retrospectively.Results:Twenty-nine patients were collected. The radiography showed the lesions involved all more than 3 lung fields. The films showed consolidation shadow in 19 cases, multiple patches of shadow in 23 cases, reticular pattern in 12 cases, strips shadow in 14 cases, interlobar fissure thickening in 18 cases, and "white lung" in 4 cases.The complications included pleural effusion in 4 cases, pneumothorax in 2 cases, mediastinal and subcutaneous emphysema in 1 case. The radiography showed the lesions progressed in 15 cases, with expanded involvement of the lung.The increase of lesion density was found in 6 cases, new lesions were noted in 5 cases, while both of them were found in 4 cases. Nine cases showed improvement, with reduced range and decreased density. Patchy or consolidation shadow turned to strips shadow or articular pattern shadow in 8 cases.There was no significant change in 3 cases with large consolidation shadow.Conclusions:Bedside chest radiography has a good value in the follow-up of severely and critically ill patients with COVID-19, and can provide great help for clinicians to evaluate their condition.
