Based on the analysis of the relevant records of the contralateral bloodletting technique, it is believed that this needling technique has 3 key characteristics, including "contralateral selection of points", "points on the four extremities dominated" and "collaterals selected rather than meridian points". Through the studies on philology and the annotation by the doctors in the past dynasties, a part of point prescriptions for the contralateral bloodletting is investigated, and those not belonged to the category of this needling technique in Suwen: Miuci Lun (On Contralateral Bloodletting) are distinguished. It is concluded that the failure of consensus-making in classifying point prescriptions is due to the lack of understanding on the characteristics of contralateral bloodletting and the misunderstanding on the errors of sentences and words. It is suggested that the study on theoretic concepts should lay on the problems relevant with the generalization and alienation of concepts. The mode of "combination of the detail with the whole" should be adopted. It starts from grasping the overall by systematic review, and followed by deliberating in details, so as to correctly identify the original concept and connotation.

Eight new diterpenoids, Isodons A-H (1-8), comprising seco-abietane and abietane-type structures, together with 13 known analogues (9-21), were isolated from Isodon lophanthoides (Buch.-Ham. ex D. Don) Hara. The compounds (+)-3/(-)-3, (+)-4/(-)-4, and (+)-5/(-)-5 were identified as three enantiomeric pairs. The planar structures and absolute configurations of 1-8 were determined through high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), 1D & 2D nuclear magnetic resonance (NMR) spectroscopy, electronic circular dichroism (ECD) calculations, and X-ray diffraction crystallography. A cholesterol 7α-hydroxylase (Cyp7a1) luciferase reporter assay revealed significant anti-cholestatic activities for compounds 1, (+)-4, 6, 7, 12-14, and 16. Additionally, compound 6 demonstrated anti-cholestatic effects through the farnesoid X receptor (FXR)-associated signaling pathways in vitro and in vivo. These findings suggest potential applications for I. Lophanthoides in pharmaceutical development.

This study started from the connotation of public welfare and, from the perspective of equal rights and responsibilities, interpreted the public welfare responsibilities and entitlements of hospitals. It developed corresponding quantitative measurement tools and constructed a Public Welfare Rights and Responsibilities Index. Public welfare responsibilities were reflected in the provision of equitable, accessible, appropriate, and reasonable basic medical and public health services. These responsibilities were quantified using the market price of basic medical services, the average cost per case-mix index unit, and public service expenditures. Entitlements were reflected in financial subsidies, tax exemptions, and land policy support. Based on this framework, the study applies the Public Welfare Rights and Responsibilities Index to evaluate 147 public hospitals in City S from 2019 to 2021. The results show that the overall level of public welfare among public hospitals in City S was relatively high (with an average index of 2.39), but showed a slight downward trend. Differences were observed across hospital grades and types, with secondary-level hospitals and general hospitals demonstrating relatively higher levels of public welfare. This study could provide a practical and quantifiable method for measuring hospital public welfare within an equal rights and responsibilities framework, offering a novel analytical tool and empirical evidence to support policy formulation and performance evaluation.

Set the control group, the low, medium and high dose groups of GP (50, 100, 200 μg/mL); Compared with the control group, the cell density decreased in the medium and high dose groups of GP, and the PI positivity, LDH release, ROS, Ca

Fetal heart rate plays an essential role in maternal and fetal monitoring and fetal health detection. In this study, a method based on Poincare Plot and LSTM is proposed to realize the high performance classification of abnormal fetal heart rate. Firstly, the original fetal heart rate signal of CTU-UHB database is preprocessed via interpolation, then the sequential fetal heart rate signal is converted into Poincare Plot to obtain nonlinear characteristics of the signals, and then SquenzeNet is used to extract the features of Poincare Plot. Finally, the features extracted by SqueezeNet are classified by LSTM. And the accuracy, the true positive rate and the false positive rate are 98.00%, 100.00%, 92.30% respectively on 2 000 test set data. Compared with the traditional fetal heart rate classification method, all respects are improved. The method proposed in this study has good performance in CTU-UHB fetal monitoring database and has certain practical value in the clinical diagnosis of auxiliary fetal heart rate detection.

Toxoplasma gondii, an intracellular protozoan parasite that infects one-third of the world’s population, has been reported to hijack host cell apoptotic machinery and promote either an anti- or proapoptotic program depending on the parasite virulence and load and the host cell type. However, little is known about the regulation of human FHs 74 small intestinal epithelial cell viability in response to T. gondii infection. Here we show that T. gondii RH strain tachyzoite infection or ESP treatment of FHs 74 Int cells induced apoptosis, mitochondrial dysfunction and ER stress in host cells. Pretreatment with 4-PBA inhibited the expression or activation of key molecules involved in ER stress. In addition, both T. gondii and ESP challenge-induced mitochondrial dysfunction and cell death were dramatically suppressed in 4-PBA pretreated cells. Our study indicates that T. gondii infection induced ER stress in FHs 74 Int cells, which induced mitochondrial dysfunction followed by apoptosis. This may constitute a potential molecular mechanism responsible for the foodborne parasitic disease caused by T. gondii.

Toxoplasma gondii is an intracellular parasite that causes severe disease when the infection occurs during pregnancy. Adenosine is a purine nucleoside involved in numerous physiological processes; however, the role of adenosine receptors in T. gondii-induced trophoblast cell function has not been investigated until now. The goal of the present study was to evaluate the intracellular signaling pathways regulated by adenosine receptors using a HTR-8/SVneo trophoblast cell model of T. gondii infection. HTR8/SVneo human extravillous trophoblast cells were infected with or without T. gondii and then evaluated for cell morphology, intracellular proliferation of the parasite, adenosine receptor expression, TNF-α production and mitogen-activated protein (MAP) kinase signaling pathways triggered by adenosine A3 receptor (A3AR). HTR8/SVneo cells infected with T. gondii exhibited an altered cytoskeletal changes, an increased infection rate and reduced viability in an infection time-dependent manner. T. gondii significantly promoted increased TNF-α production, A3AR protein levels and p38, ERK1/2 and JNK phosphorylation compared to those observed in uninfected control cells. Moreover, the inhibition of A3AR by A3AR siRNA transfection apparently suppressed the T. gondii infection-mediated upregulation of TNF-α, A3AR production and MAPK activation. In addition, T. gondii-promoted TNF-α secretion was dramatically attenuated by pretreatment with PD098059 or SP600125. These results indicate that A3AR-mediated activation of ERK1/2 and JNK positively regulates TNF-α secretion in T. gondii-infected HTR8/SVneo cells.

The discovery and application of Lanwei (EX-LE 7) was reviewed to elaborate its enlightenment on the inheritance and innovation of acupuncture. Literature published before April of 2017 was searched in CNKI and VIP database with"Lanwei (EX-LE 7)"and"acupuncture"as key words. Related references and publications were retrieved. According to the purpose, literature was screened and key information was extracted to perform systematic review and analysis. The results indicated Lanwei (EX-LE 7), reflection of relationship between organ and body surface under the guidance of acupuncture and meridians theory, was not a point, but an area. The discovery and application of Lanwei (EX- LE 7) was the product of western and Chinese combination. The best indication was simple appendicitis, but operation should be applied once adhesion, purulent and perforation occurred. It is indicated to improve clinical efficacy and avoid accident, the reasoned core of theory system should be insisted and the communication with modern medicine should be reinforced.
