From the perspective of circular RNA forkhead box protein O3(circFOXO3) regulating glycolysis in osteoarthritis(OA) chondrocytes, this study investigated the mechanism by which Tougu Xiaotong Capsules(TGXTC) alleviated OA degeneration. In in vivo experiments, after randomized grouping and relevant interventions, morphological staining was used to observe structural changes in cartilage tissue. The mRNA level of circFOXO3 in cartilage tissue was detected by real-time quantitative PCR(RT-qPCR). Western blot analysis was used to detect changes in the expression of glucose transporter 1(GLUT1), hexokinase 2(HK2), pyruvate kinase M2(PKM2), lactate dehydrogenase A(LDHA), and matrix metalloproteinase 13(MMP13). In in vitro experiments, fluorescence in situ hybridization(FISH) was used to detect circFOXO3 expression in chondrocytes from each group. A lentiviral vector was used to construct circFOXO3-silenced(sh-circFOXO3) chondrocytes. RT-qPCR was used to analyze the changes in circFOXO3 levels after silencing, and Western blot was used to assess the regulatory effects of TGXTC on GLUT1, HK2, PKM2, LDHA, and MMP13 proteins in interleukin-1β(IL-1β)-induced chondrocytes under sh-circFOXO3 conditions. Masson staining and alcian blue staining results showed that the cartilage layer structure in the TGXTC and positive drug groups was improved compared with that in the model group. The mRNA level of circFOXO3 was significantly upregulated in both the TGXTC and positive drug groups, while the expression of the above-mentioned proteins was significantly reduced. FISH results showed that TGXTC upregulated the fluorescence intensity of circFOXO3 in IL-1β-induced chondrocytes. In the circFOXO3 silencing experiment, compared with the IL-1β group, circFOXO3 levels in the IL-1β + sh-circFOXO3 group were significantly decreased. Compared with the IL-1β + TGXTC group, circFOXO3 levels were significantly reduced in the IL-1β + sh-circFOXO3 + TGXTC group. Western blot results indicated that the elevated levels of GLUT1, HK2, PKM2, LDHA, and MMP13 proteins in chondrocytes of the IL-1β group were significantly inhibited by TGXTC intervention. However, this regulatory effect was attenuated after circFOXO3 silencing. In conclusion, TGXTC alleviate glycolytic metabolism disorder in OA chondrocytes and delay OA degeneration by regulating circFOXO3.

Adequate inflammation can effectively eliminate harmful substances and prevent disease as a self-protective measure to prevent further damage to the body,while abnormally activated inflammation is detrimental to the body.Nucleotide binding and oligomerization domain-like receptor protein 3(NLRP3)inflammasome that participates in inflammatory responses are closely related to many physiological and pathological processes and play an important role in the occurrence and development of pulmonary diseases.This article mainly reviewed the activation mechanism and hypothesis of NLRP3 inflammasome,as well as the research on treating respiratory diseases by interfering with NLRP3 inflammasome.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective: To compare the safety and efficacy of different anticoagulants in patients with indications for anticoagulation after transcatheter aortic valve replacement (TAVR). Methods: This is a retrospective study. Patients who underwent TAVR from April 2016 to February 2022 in Guangdong Provincial People's Hospital and had indications for anticoagulation were included and divided into two groups according to the type of anticoagulants, i.e. non-vitamin K antagonist oral anticoagulant (NOAC) and warfarin, and patients were followed up for 30 days. The primary endpoint was the combination of death, stroke, myocardial infarction, valve thrombosis, intracardiac thrombosis and major bleeding. The incidence of endpoints was compared between two groups, and multivariate logistic regression analysis was applied to adjust the bias of potential confounders. Results: A total of 80 patients were included. Mean age was (74.4±7.1) years, 43 (53.8%) were male. Forty-nine (61.3%) patients used NOAC, 31 used warfarin, and major indication for anticoagulants was atrial fibrillation (76/80, 95.0%). The adjusted risks of the primary endpoint (OR=0.23, 95%CI 0.06-0.94, P=0.040) of NOAC were lower than that of warfarin, mainly driven by a lower risk of major bleeding (OR=0.19, 95%CI 0.04-0.92, P=0.039). Conclusions: The short-term outcome of NOAC is better than that of warfarin in patients with indications for anticoagulation after TAVR. Randomized controlled trials of large sample size with long-term follow-up are needed to further testify this finding.

This study explored the feasibility of mineral element content and ratios of nitrogen isotopes to discriminate the cultivation mode of Dendrobium nobile in order to provide theoretical support for the discrimination of the cultivation mode of D. nobile. The content of 11 mineral elements(N, K, Ca, P, Mg, Na, Fe, Cu, Zn, Mn, and B) and nitrogen isotope ratios in D. nobile and its substrate samples in three cultivation methods(greenhouse cultivation, tree-attached cultivation, and stone-attached cultivation) were determined. According to the analysis of variance, principal component analysis, and stepwise discriminant analysis, the samples of different cultivation types were classified. The results showed that the nitrogen isotope ratios and the content of elements except for Zn were significantly different among different cultivation types of D. nobile(P<0.05). The results of correlation analysis showed that the nitrogen isotope ratios, mineral element content, and effective component content in D. nobile were correlated with the nitrogen isotope ratio and mineral element content in the corresponding substrate samples to varying degrees. Principal component analysis can preliminarily classify the samples of D. nobile, but some samples overlapped. Through stepwise discriminant analysis, six indicators, including δ~(15)N, K, Cu, P, Na, and Ca, were screened out, which could be used to establish the discriminant model of D. nobile cultivation methods, and the overall correct discrimination rates after back-substitution test, cross-check, and external validation were all 100%. Therefore, nitrogen isotope ratios and mineral element fingerprints combined with multivariate statistical analysis could effectively discriminate the cultivation types of D. nobile. The results of this study provide a new method for the identification of the cultivation type and production area of D. nobile and an experimental basis for the quality evaluation and quality control of D. nobile.

Objective:To study the feasibility of control charts in the quality management of hospital statistical data as a reference for improving such management.Methods:Main business indicators of the main campus and some business indicators of the affiliated campus of a tertiary general hospital from January to May 2022 were selected. K-S test and chi-square goodness of fit test were used to test data in its statistical daily report, analyzing whether the data conform to the specific distributions. Then appropriat control chart were used according to the data type and distribution type. Minitab 21.1 software was used to draw the hospital data quality control chart, and data quality was monitored by analyzing the distribution of data points in the control chart.Results:The test found that the number of admissions, ultrasound examinations and emergency department visits in the main campus, and CT examinations in the affiliated campus, conformed to normal distribution, and single value control charts were applied. The number of ambulance trips in the main campus and the affiliated campus conform to Poisson distribution, and the defect number control chart was applied. The number of inpatient deaths in the main campus conform to a geometric distribution, and a rare event control chart was applied. The volume of admissions and ultrasound examinations in the main campus were mostly influenced by other factors, and the single-value selective control chart was used to further determine the cause of abnormal data distribution. The results of the control chart analysis showed that, there were no abnormal points in the data distribution of admissions, color ultrasound volume and in-hospital deaths in the main campus, two abnormal points in the CT examination volume in the affiliated campus. The control charts for the number of emergency department visits in the main campus and the number of ambulance trips in the main and affiliated campuses each had one outlier. It was verified that one anomaly in the volume of CT examinations in the affiliated campus and one anomaly in the number of ambulance trips in the affiliated campus were caused by data errors, while the other data were correct.Conclusions:It is feasible to use control charts to monitor the quality of hospital data, which can be used as a quality management tool to assist the quality management of hospital data.

Licking behavior is important for water intake. The deep mesencephalic nucleus (DpMe) has been implicated in instinctive behaviors. However, whether the DpMe is involved in licking behavior and the precise neural circuit behind this behavior remains unknown. Here, we found that the activity of the DpMe decreased during water intake. Inhibition of vesicular glutamate transporter 2-positive (VGLUT2⁺) neurons in the DpMe resulted in increased water intake. Somatostatin-expressing (SST⁺), but not protein kinase C-δ-expressing (PKC-δ⁺), GABAergic neurons in the central amygdala (CeA) preferentially innervated DpMe VGLUT2⁺ neurons. The SST⁺ neurons in the CeA projecting to the DpMe were activated at the onset of licking behavior. Activation of these CeA SST⁺ GABAergic neurons, but not PKC-δ⁺ GABAergic neurons, projecting to the DpMe was sufficient to induce licking behavior and promote water intake. These findings redefine the roles of the DpMe and reveal a novel CeA^SST-DpMe^VGLUT2 circuit that regulates licking behavior and promotes water intake.
