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 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.

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 （FEV_0.3）， FEV_0.3/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 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.

ObjectiveTo compare and analyze the effect of tubular gastric transsternal route and posterior mediastinal route combined with postoperative adjuvant radiotherapy on the short-term complications and safety of minimally invasive Mckeown esophageal carcinoma resection. MethodsRetrospective analysis of 89 patients who underwent minimally invasive Mckeown esophagectomy in the Department of thoracic surgery of the First Affiliated Hospital of China University of science and technology from January 2020 to June 2021. Some patients received postoperative adjuvant radiotherapy. According to the tubular gastric lifting pathway， they were divided into two groups： retrosternal route group and posterior mediastinal route group， including 39 cases in the retrosternal route group and 50 cases in the posterior mediastinal route group. The clinical characteristics and perioperative complications of the two groups were compared. ResultsThere was no significant difference in clinical characteristics between the two groups （P>0.05）； there was no significant difference in operation time， intraoperative bleeding， postoperative drainage and postoperative hospital stay between the two groups （P>0.05）. In addition， the incidence of pulmonary infection in the posterior mediastinal pathway group was higher than that in the retrosternal pathway group， and the difference was not statistically significant （P>0.05）. The incidence of gastroesophageal reflux in the posterior mediastinal route group was higher than that in the retrosternal route group， and the difference was statistically significant （P<0.05）. A total of 30 patients received adjuvant radiotherapy （10 cases in the retrosternal route group and 20 cases in the posterior mediastinal route group）. The incidence of radioactive gastritis in the retrosternal route group was lower than that in the posterior mediastinal route group （1 case had acute radioactive esophagitis， grade 1； In the posterior mediastinal route group， 6 patients developed acute radiation esophagitis （gastritis）， there were 2 cases in grade 1 and 4 cases in grade 2）. ConclusionThe short-term efficacy and safety of tubular gastric retrosternal route and posterior mediastinal route in minimally invasive Mckeown esophagectomy are consistent， but the incidence of gastroesophageal reflux after retrosternal route is lower.

OBJECTIVE: To investigate the application effect of sequential autologous hematopoietic stem cell transplantation (Auto-HSCT) with lenalidomide, bortezomib and dexamethasone (RVD) in the treatment of multiple myeloma (MM) evaluated by propensity score matching. METHODS: The clinical data of 49 MM patients treated with RVD scheme and followed-up for 36 months in the hospital from January 2015 to January 2021 were retrospectively analyzed and included in the control group, the clinical data of 54 MM patients who received RVD scheme and sequential Auto-HSCT scheme and completed 36 months of follow-up in the hospital during the same period were collected and included in the observation group. PSM method (1∶1, caliper value=0.01) was used to match the control group with the observation group based on baseline data and laboratory indexes, covariate equilibrium samples were obtained between groups (40 cases in each group). The clinical efficacy of patients in the two groups after 18 weeks of treatment was compared; the incidence of toxic and side effects during treatment of patients in the two groups was compared; the survival of patients in the two groups was compared after 36 months of follow-up. RESULTS: The ORR and DCR in the observation group were higher than those in the control group, the difference was statistically significant (P<0.05). Compared the incidence of fatigue, rash, thrombocytopenia, anemia and nausea of patients in the two groups, there was no statistical significant difference (P>0.05). After 36 months of follow-up (no loss during follow-up), 4 cases died from illness in the observation group, with a survival rate of 90% and an average survival time of 35.61 (95% CI: 35541-35.685) months, 10 cases died from illness in the control group, with a survival rate of 75% and an average survival time of 34.70 (95% CI: 34.559-34.832) months, the survival rate of the observation group was higher than that of the control group, the difference was statistically significant (P<0.05). CONCLUSION Sequential Auto-HSCT with RVD regimen in the treatment of MM can improve the short-term efficacy and increase the survival rate of patients, which will not increase toxic and side effects and has high safety.
