		                        			ObjectiveTo explore the mechanism of Dendrobium huoshanense polysaccharide (DHP) against inflammatory damage of neurons in Parkinson's disease (PD) model. MethodSH-SY5Y cells were randomized into blank group, model group, and DHP group. The survival rate of cells was measured by thiazole blue(MTT) assay, and the levels of lactate dehydrogenase (LDH), reactive oxygen species (ROS), malondialdehyde (MDA), and superoxide dismutase (SOD) were measured by colorimetric analysis. BV-2 microglia were classified into blank group, model group, DHP group, and MCC950 group (positive control group), and enzyme-linked immunosorbent assay (ELISA) was applied to detect the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-18 (IL-18). The expression of NOD-like receptor protein 3 (NLRP3), adaptor protein apoptosis-associated dot protein (ASC), cysteine aspartic protease-1 (Caspase-1), and IL-1β was measured by Western blot. A total of 50 C57BL/6 mice were randomized into blank group, model group, DHP low-dose (100 mg·kg-1) group, DHP equivalent-dose (350 mg·kg-1) group, and MCC950 group (positive control group), 10 mice in each group. The motor balance and coordination of C57BL/6 mice were observed by beam walking test, tail suspension test and rotarod test. The levels of Iba-1 and tyrosine hydroxylase (TH) were detected by immunofluorescence staining. The damage of dopaminergic neurons in the substantia nigra was detected by FJB staining. The levels of inflammatory factors such as IL-1β, IL-18, and TNF-α in mouse midbrain tissues were detected by ELISA and the protein levels of NLRP3, ASC, Caspase-1, and IL-1β protein were measured by Western blot. ResultCompared with the blank group, the SH-SY5Y model group showed decreased cell survival, increased levels of LDH, ROS, and MDA (P<0.05), and decreased levels of SOD (P<0.05). Compared with the model group, the DHP group demonstrated increased cell survival, decreased levels of LDH, ROS, and MDA (P<0.01), and increased level of SOD (P<0.01). Compared with the blank group, BV-2 model group had high levels of IL-1β, IL-18, and TNF-α (P<0.05) and high protein expression of NLRP3, Caspase-1, IL-1β, and ASC (P<0.05). Compared with the model group, DHP and MCC950 groups demonstrated low levels of IL-1β, IL-18, and TNF-α (P<0.01) and low protein expression of NLRP3, Caspase-1, IL-1β, and ASC (P<0.01). Compared with the blank group, the C57BL/6 model group displayed long time to pass the balance wood (P<0.05), short time spent on the rod in the rotarod test (P<0.05), high levels of IL-1β, IL-18, and TNF-α (P<0.05) and expression of Iba-1 in the midbrain substantia nigra (P<0.05), low TH expression (P<0.05), more positive neurons in the FJB staining (P<0.05), and high expression of NLRP3, Caspase-1, ASC, and IL-1β proteins (P < 0.05). Compared with the model group, the mice in the DHP and MCC950 groups had short time to pass the balance beam (P<0.01), long time spent on the rod (P<0.01), low levels of IL-1β, IL-18, and TNF-α (P<0.01), low Iba-1 expression in midbrain substantia nigra (P<0.01), high TH expression (P<0.01), and small number of positive neurons in the midbrain substantia nigra (P<0.01). The expression of NLRP3, ASC, and IL-1β proteins was lower in the MCC950 group (P<0.01), and the expression of NLRP3, ASC, Caspase-1 and IL-1β proteins was lower in the DHP equivalent-dose group (P<0.01) than in the model group. ConclusionDHP has anti-oxidative stress effect. It regulates the expression of NLRP3 inflammasome and inhibits the overactivation of microglia, thereby alleviating the neuroinflammatory injury in PD and exerting the neuroprotective effect.

		                        			This study aimed to explore the underlying framework and data characteristics of Tibetan prescription information. The information on Tibetan medicine prescriptions was collected based on 11 Tibetan medicine classics, such as Four Medical Canons(Si Bu Yi Dian). The optimal classification method was used to summarize the information structure of Tibetan medicine prescriptions and sort out the key problems and solutions in data collection, standardization, translation, and analysis. A total of 11 316 prescriptions were collected, involving 139 011 entries and 63 567 pieces of efficacy information of drugs in prescriptions. The information on Tibe-tan medicine prescriptions could be summarized into a "seven-in-one" framework of "serial number-source-name-composition-efficacy-appendix-remarks" and 18 expansion layers, which contained all information related to the inheritance, processing, origin, dosage, semantics, etc. of prescriptions. Based on the framework, this study proposed a "historical timeline" method for mining the origin of prescription inheritance, a "one body and five layers" method for formulating prescription drug specifications, a "link-split-link" method for constructing efficacy information, and an advanced algorithm suitable for the research of Tibetan prescription knowledge discovery. Tibetan medicine prescriptions have obvious characteristics and advantages under the guidance of the theories of "three factors", "five sources", and "Ro-nus-zhu-rjes" of Tibetan medicine. Based on the characteristics of Tibetan medicine prescriptions, this study proposed a multi-level and multi-attribute underlying data architecture, providing new methods and models for the construction of Tibetan medicine prescription information database and knowledge discovery and improving the consistency and interoperability of Tibetan medicine prescription information with standards at all levels, which is expected to realize the "ancient and modern connection-cleaning up the source-data sharing", so as to promote the informatization and modernization research path of Tibetan medicine prescriptions.

		                        			ObjectiveTo establish and evaluate a chronic obstructive pulmonary disease (COPD) model with lung-spleen qi deficiency. MethodA rat model mimicking COPD with lung-spleen qi deficiency was established by the combination of cigarette smoking and intratracheal instillation of lipopolysaccharide (LPS) along with gavage of Sennae Folium infusion. Forty male SPF-grade SD rats were randomly assigned to blank, model, and low- (L-FXY), medium- (M-FXY), and high-dose (H-FXY) Sennae Folium infusion groups. Other groups except the blank group were exposed to daily cigarette smoke, with LPS administrated via intratracheal instillation on the 1st and 14th days. On the 28th day of modeling, the L-FXY, M-FXY, and H-FXY groups were administrated with Sennae Folium infusion at 5, 10, and 20 g·kg-1, respectively, and at 4 ℃ for three weeks. The modeling lasted for 49 days. The general conditions (body mass, food intake, fecal water content, and anal temperature) and behaviors (grip strength test and tail suspension test) of rats in different groups were examined. The lung function, lung histopathology, D-xylose, amylase, and gastrin levels in the serum, interleukin(IL)-1β and IL-6 levels in the alveolar lavage fluid, levels of T-lymphocyte subsets (CD4+, CD8+, and CD4+/CD8+) in the peripheral blood, and thymus and spleen indices were measured. ResultTwo rats died in the H-FXY group. Compared with the blank group, both the M-FXY and H-FXY groups exhibited reduced body mass and food intake (P<0.01) and increased fecal water content (P<0.01). The anal temperature in the H-FXY group was lower than that in the blank group (P<0.01). The grip strength decreased in the modeling groups compared with the blank group (P<0.01), and the duration of immobility in the tail suspension test increased in the M-FXY and H-FXY groups (P<0.05, P<0.01). Compared with the blank group, the modeling groups showed reduced 0.3 second forced expiratory volume (FEV0.3), FEV0.3/forced vital capacity (FVC)(P<0.01), thickening of bronchial walls, proliferation of goblet cells, and the presence of emphysematous changes. In terms of gastrointestinal function, the M-FXY and H-FXY groups had lower levels of D-xylose, gastrin, and α-amylase than the blank group (P<0.01). Regarding the immune and inflammatory indices, the M-FXY and H-FXY groups showed lower thymus and spleen indices than the blank group (P<0.01). Compared with the blank group, the modeling groups presented lowered CD4+ level (P<0.01) and CD4+/CD8+ ratio (P<0.05, P<0.01) in the peripheral blood and elevated levels of IL-1β and IL-6 in the alveolar lavage fluid (P<0.01) than the blank group. ConclusionA model of COPD with lung-spleen Qi deficiency was established through the combination of daily cigarette smoke, intratracheal instillation with LPS, and gavage of Sennae Folium infusion. The comprehensive evaluation results suggested medium-dose (10 g·kg-1) Sennae Folium infusion for gavage during the modeling of COPD with lung-spleen Qi deficiency.

		                        			Objective: To analyze the impact of metabolic risk factors on the epidemiological characteristics of the reactivation of inactive HBsAg carriers (IHC) and provide effective intervention measures to standardize the management of chronic hepatitis B infections. Methods: Based on the chronic hepatitis B infection cohort established in 2010 in Jiangsu province, six follow-up visits from 2012 to 2020 were conducted to analyze the characteristics and influencing factors of the hepatitis B reactivation of IHC and the impact of metabolic risk factors, including obesity, high blood pressure, diabetes and hyperglycemia. Results: From 2012 to 2020, 2 527 IHC and 17 730 person-years were observed during a median follow-up period of 7.0 person-years. Ninety-eight cases of hepatitis B reactivation, with a cumulative reaction rate, was 3.9%, and the incidence density was 5.53/1 000 person-years. Multivariate Cox proportional risk regression analysis showed that age and baseline HBV DNA were independent risk factors of HBV reactivation. Compared with the patients ≥60 years, 40-49 age group (aHR=2.16, 95%CI:1.20-3.90) and 20-29 age group (aHR=5.48, 95%CI:2.07-14.48) were significantly associated with hepatitis B reactivation. Compared with the HBV DNA negative patients at baseline, the risk of hepatitis B reactivation was higher in the group with low HBV DNA level 100-1 999 IU/ml (aHR=1.67, 95%CI:1.11-2.52). Stratification analysis results showed that compared with those without metabolic risk factors, in the ≥50 age group, patients with ≥2 metabolic risk factors showed adjusted HR of 2.73 (95%CI:1.08-6.96). Conclusions: The risk of hepatitis B being reactive is the persistent existence of IHC in communities in Jiangsu province, especially young adults, low-level HBV DNA carriers, and IHC with ≥2 metabolic risk factors. Follow-up for these IHC should be strengthened to reduce the risk of disease progression by antiviral treatment at the right time.

		                        			Objective: To summarize the clinical features, management and outcome of superior vena cava syndrome (SVCS) associated with mediastinal malignancy in children. Methods: Clinical data of 42 children of SVSC associated with mediastinal malignancy in Shanghai Children's Medical Center from January 2015 to December 2021 were collected and analyzed retrospectively. The clinical manifestations, pathological diagnosis, disease diagnosis process, and prognosis were summarized. Results: Among 42 children of SVCS associated with mediastinal malignancy, there were 31 males and 11 females. The age at diagnosis was 8.5 (1.9, 14.9) years. Cough and wheezing (33 cases, 79%), orthopnea (19 cases, 45%) and facial edema (18 cases, 43%) occurred most commonly. T-cell lymphoblastic lymphoma (T-LBL) was the most frequent pathological diagnosis (25 cases, 60%), followed by T-cell acute lymphoblastic leukemia (T-ALL) (7 cases, 17%), anaplastic large cell lymphoma (4 cases, 10%) and diffuse large B-cell lymphoma (2 cases, 5%), peripheral T-lymphoma, Hodgkin lymphoma, Ewing's sarcoma and germ cell tumor (1 case each). Pathological diagnosis was confirmed by bone marrow aspiration or thoracentesis in 14 cases, peripheral lymph node biopsy in 6 cases, and mediastinal biopsy in 22 cases. Twenty-seven cases (64%) had local anesthesia. Respiratory complications due to mediastinal mass developed in 3 of 15 cases who received general anesthesia. Of the 42 cases, 27 cases had sustained remission, 1 case survived with second-line therapy after recurrence, and 14 cases died (2 cases died of perioperative complications and 12 cases died of recurrence or progression of primary disease). The follow-up time was 36.7 (1.2, 76.1) months for 27 cases in continuous complete remission. The 3-year overall survival (OS) and events free survival (EFS) rates of 42 children were 59% (95%CI 44%-79%) and 58% (95%CI 44%-77%) respectively. Conclusions: SVCS associated with mediastinal malignancy in children is a life-threatening tumor emergency with high mortality. The most common primary disease is T-LBL. The most common clinical symptoms and signs are cough, wheezing, orthopnea and facial edema. Clinical management should be based on the premise of stable critical condition and confirm the pathological diagnosis through minimal invasive operation.

		                        			Objective    To explore the mechanism of dihydrouridine synthase 4-like (DUS4L) on the development of lung adenocarcinoma (LUAD). Methods    The RNA-seq expression data of LUAD was downloaded from The Cancer Genome Atlas (TCGA), and the relationship between its clinical pathological characteristics and DUS4L mRNA expression was evaluated. The effect of DUS4L knockdown on the proliferation of A549 cells was detected by EDU proliferation assay. The gene expression profile of lung adenocarcinoma A549 cells in the DUS4L knockdown group (KD group) and control group (NC group) was detected by transcriptome sequencing technique. The differential genes were screened by DESeq2. ClusterProfiler was used to perform GO functional enrichment analysis of differential genes. Results    The expression of DUS4L mRNA in LUAD tissues was higher than that in normal tissues, and the up-regulation of DUS4L was related to the clinical pathological characteristics of LUAD patients. EDU proliferation assay suggested that knocking down DUS4L could inhibit the proliferation of A549 cells. A total of 456 differential genes were screened, including 289 up-regulated genes and 167 down-regulated genes [|log2(fold change)|>1 and Padj<0.05]. STC2 and TRIB3 were significantly down-regulated (P<0.05). Differential genes were mainly involved in the production of interleukin-8, angiogenesis, vascular endothelial cell proliferation and other biological pathways. Conclusion    DUS4L can widely regulate the gene expression of LUAD cells, which provides a new idea for further studying the function and role of DUS4L in the occurrence and development of LUAD and finding new therapeutic targets for LUAD.
