Traditional Chinese medicine(TCM) resources are the essential material foundation for the development of TCM. The national survey of TCM resources serves as a periodic summary of these resources, ensuring the continuity, prosperity, and development of TCM in China. Since 1949, four national surveys of TCM resources have been conducted. The fourth survey incorporated an investigation into traditional knowledge related to TCM resources, including the traditional medicinal knowledge of Chinese ethnic minorities, with the goal of systematically exploring, preserving, and inheriting this knowledge. This manuscript provides an overview of the basic findings from the first three national surveys of TCM resources, while also clarifying the concepts, categories, forms, carriers, and acquisition pathways of traditional knowledge related to TCM resources. A preliminary summary of the findings from traditional knowledge investigations reported in current literature is also presented. Based on the fourth survey, this manuscript emphasizes the urgency of developing public medical knowledge through empirically-based investigations, the excavation, and compilation of traditional knowledge. It also outlines the potential for conducting "precise" investigations based on first-hand data obtained from the survey, as well as facilitating the discovery and evaluation of new medicines using traditional knowledge related to ethnic minority medicinal practices. This manuscript is expected to provide valuable insights for promoting the health and industrial development of ethnic minority populations in the post-"survey" phase.

This paper explored the specific mechanism of ginsenoside Rg_1 in regulating mitochondrial fusion through the neurogenic gene Notch homologous protein 1(Notch1) pathway to alleviate hypoxia/reoxygenation(H/R) injury in HL-1 cells. The relative viability of HL-1 cells after six hours of hypoxia and two hours of reoxygenation was detected by cell counting kit-8(CCK-8). The lactate dehydrogenase(LDH) activity in the cell supernatant was detected by the lactate substrate method. The content of adenosine triphosphate(ATP) was detected by the luciferin method. Fluorescence probes were used to detect intracellular reactive oxygen species(Cyto-ROS) levels and mitochondrial membrane potential(ΔΨ_m). Mito-Tracker and Actin were co-imaged to detect the number of mitochondria in cells. Fluorescence quantitative polymerase chain reaction and Western blot were used to detect the mRNA and protein expression levels of Notch1, mitochondrial fusion protein 2(Mfn2), and mitochondrial fusion protein 1(Mfn1). The results showed that compared with that of the control group, the cell activity of the model group decreased, and the LDH released into the cell culture supernatant increased. The level of Cyto-ROS increased, and the content of ATP decreased. Compared with that of the model group, the cell activity of the ginsenoside Rg_1 group increased, and the LDH released into the cell culture supernatant decreased. The level of Cyto-ROS decreased, and the ATP content increased. Ginsenoside Rg_1 elevated ΔΨ_m and increased mitochondrial quantity in HL-1 cells with H/R injury and had good protection for mitochondria. After H/R injury, the mRNA and protein expression levels of Notch1 and Mfn1 decreased, while the mRNA and protein expression levels of Mfn2 increased. Ginsenoside Rg_1 increased the mRNA and protein levels of Notch1 and Mfn1, and decreased the mRNA and protein levels of Mfn2. Silencing Notch1 inhibited the action of ginsenoside Rg_1, decreased the mRNA and protein levels of Notch1 and Mfn1, and increased the mRNA and protein levels of Mfn2. In summary, ginsenoside Rg_1 regulated mitochondrial fusion through the Notch1 pathway to alleviate H/R injury in HL-1 cells.

OBJECTIVES: To study the epidemiological characteristics of respiratory syncytial virus (RSV) infection in hospitalized children with community-acquired pneumonia (CAP) in Hebei Province. METHODS: Hospitalized children with CAP who tested positive for RSV and were admitted to Hebei Children's Hospital from various cities and counties across Hebei Province between January 2019 and December 2023 were included in the study. Clinical data were collected and analyzed to assess epidemiological characteristics. RESULTS: The clinical data of 43 978 children with CAP were collected, with an overall RSV detection rate of 25.98%. The detection rate was higher during the implementation of non-pharmaceutical interventions (NPIs) (30.60%) than in the non-NPIs period. Winter and spring were the primary epidemic seasons for RSV each year except in 2022. The detection rate in males (26.62%) was higher than in females (25.06%) (P<0.001). The highest detection rate (59.18%) was found in infants aged 29 days to <1 year. Single RSV infection was more common, with rhinovirus being the most frequent co-infection. CONCLUSIONS The overall RSV detection rate in Hebei Province is influenced by NPIs, being higher during their implementation. RSV predominantly circulates in winter and spring. The detection rate of RSV is higher in males and infants. RSV infection is primarily single, most often co-occurring with rhinovirus.

BACKGROUND:Due to the mismatch between the design of the proximal femoral nail antirotation Asian version(PFNA-Ⅱ)and Asian population,extrusion of the proximal femoral intertrochanteric nail may occur in the treatment of femoral intertrochanteric fractures.The influence of the protruding length on the curative effect of the operation needs to be further discussed. OBJECTIVE:To quantitatively measure the protruding length of the proximal trochanter of the femur with intramedullary nail after PFNA-Ⅱ,and to analyze the effect of protruding length on the efficacy of PFNA-Ⅱ in the treatment of femoral intertrochanteric fractures. METHODS:Totally 68 patients with femoral intertrochanteric fractures treated with PFNA-Ⅱ internal fixation in the First Affiliated Hospital of Anhui Medical University were selected.The extramedullary process of the proximal trochanter of the femur was quantitatively measured on the anterior and posterior X-ray films of the hip joint within 6 months after operation.According to the existence of extrusion of the proximal trochanter intramedullary nail,the patients were divided into protruding group and non-protruding group.The data of sex,height,fracture type,length and diameter of the intramedullary nail,the position of screw blade in the femoral neck and protruding length of proximal greater trochanter were collected.The postoperative curative effect was judged by visual analog scale pain score and hip joint Harris score at 6 months after operation.The influence of protruding proximal trochanter of the PFNA-Ⅱ intramedullary nail on the operative effect was observed. RESULTS AND CONCLUSION:(1)There were significant differences in sexual characteristics between the protruding group and the non-protruding group(P=0.001).(2)According to AO/OTA classification,there were no significant differences in fracture type between the protruding group and the non-protruding group(P=0.289).(3)There was no significant difference in the length and diameter of the intramedullary nail between the two groups(P=0.067,P=1.000).(4)There was no significant correlation between the height of all patients and the length of the intramedullary nail(P=0.510),but there was a significant correlation between height and protruding length(P=0.034).There was no significant correlation between screw blade position and protruding length(P=0.968).(5)Six months after operation,there was no significant difference in the hip Harris score(P=0.373),but the visual analog scale pain score was significantly higher in the protruding group than that in the non-protruding group(P=0.000).(6)The results suggest that nail extrusion often occurs in the proximal greater trochanter when PFNA-Ⅱ is used in the treatment of intertrochanteric fractures in Asians.When the nail extended into the proximal soft tissue of the greater trochanter,patients complained of proximal greater trochanteric pain and the visual analog scale score of proximal greater trochanter pain in the patient was significantly higher than that in the non-protruding group.To be more suitable for the Asian population,we suggest that the PFNA-Ⅱ should be improved to further shorten the proximal nail end to obtain better clinical results of femoral intertrochanteric fracture fixation.

This article summarizes the current research progress of natural drugs in the prevention and treatment of respiratory viruses, classifies the action mechanism of the active components of natural drugs against respiratory viruses, to provide reference basis for clinical treatment and drug discovery of respiratory diseases in the future.

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.

This study aimed to investigate the potential mechanism and the compatibility significance of Tanyu Tongzhi Formula in treating atherosclerosis(AS) in mice based on the transforming growth factor-β(TGF-β)/Smad2/3 signaling pathway. Eight C57BL/6J mice were as assigned to a normal control group and fed a regular diet, while 35 ApoE~(-/-) mice of the same strain were fed a high-fat diet for 8 weeks to establish an AS model. The model mice were randomly divided into a model group, a Tanyu Tongzhi group(18.2 mg·kg~(-1)), a Huatan(phlegm-resolving) group(10.4 mg·kg~(-1)), and a Quyu(blood stasis-resolving) group(7.8 mg·kg~(-1)), with 8 mice in each group. Except for the normal group, all other groups continued to be fed a high-fat diet for 8 weeks to maintain the AS model, and then the mice were treated by gavage for 8 weeks. Plasma levels of total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), interleukin-1β(IL-1β), and interleukin-18(IL-18) were measured using enzyme-linked immunosorbent assay(ELISA). Hematoxylin and eosin(HE) staining, oil red O staining, and Russell-Movat pentachrome staining were performed to observe the pathological changes in the aortic tissue. The proportions of aortic plaque area, lipid-stained area, collagen fibers, and elastic fibers were calculated. Immunofluorescence was used to detect the protein expression levels of matrix metalloproteinase 2(MMP2) and tissue inhibitor of metalloproteinases 2(TIMP2). Western blot was used to detect the protein expression levels of TGF-β1, TGF-β2, Smad2/3, and Smad7 in aortic tissue. Real-time fluorescence quantitative PCR(RT-qPCR) was used to measure the mRNA expression levels of TGF-β receptor(TGF-βR), TGF-β1, Smad2/3, Smad7, intercellular adhesion molecule-1(ICAM-1), and vascular cell adhesion molecule-1(VCAM-1) in aortic tissue. The results showed that compared with the normal control group, the model group had increased plasma TC and LDL-C, significantly decreased HDL-C, and significantly elevated plasma IL-1β and IL-18 levels. The model group also exhibited an increased proportion of aortic plaque area, lipid-stained area, and collagen fiber area, along with significantly upregulated MMP2 and downregulated TIMP2 expression in the aortic arch. Additionally, the expression levels of TGF-βR, TGF-β1, and p-Smad2/3 proteins and mRNA in the aortic tissue were significantly elevated, while Smad7 expression was decreased. Compared with the model group, the Tanyu Tongzhi group showed significantly reduced plasma TC and LDL-C levels, significantly increased HDL-C levels, and significantly decreased plasma IL-1β and IL-18 levels. The Tanyu Tongzhi group also exhibited a significant reduction in aortic plaque size and severity, a significant downregulation of MMP2 expression in the aortic arch, and significantly decreased ICAM-1 and VCAM-1 mRNA expression levels. Moreover, the Tanyu Tongzhi group demonstrated significantly reduced expression levels of TGF-β1 and p-Smad2/3 proteins and mRNA in the aortic tissue, and an increased expression level of Smad7 protein to varying degrees. Compared with the Tanyu Tongzhi group, the Quyu group had significantly higher LDL-C levels and elevated plasma IL-1β and IL-18 levels. The Huatan group showed upregulated MMP2 expression and downregulated TIMP2 expression in the aortic arch. In conclusion, Tanyu Tongzhi Formula, which is composed based on the pathogenesis of phlegm and blood stasis, maintains vascular homeostasis by primarily regulating lipid metabolism and controlling inflammatory factors through the Huatan group, and maintaining vascular wall permeability, inhibiting plaque development, and stabilizing plaques through the Quyu group. The mechanism of action may involve inhibiting TGF-β1 expression in the aorta, reducing Smad2/3 phosphorylation, and simultaneously increasing Smad7 expression.

This article explored the specific mechanism by which ginsenoside Rg_1 regulates cellular autophagy to attenuate hypoxia/reoxygenation(H/R) injury in HL-1 cardiomyocytes through the microRNA155(miR-155)/neurogenic gene Notch homologous protein 1(Notch1)/hairy and enhancer of split 1(Hes1) pathway. An HL-1 cell model with H/R injury was constructed, and ginsenoside Rg_1 and/or Notch1 inhibitor DAPT and miR-155 mimics were used to treat cells. Cell counting kit(CCK)-8 was used to detect the relative viability of HL-1 cells with H/R injury. The lactate dehydrogenase(LDH) content in cell culture medium supernatant was detected by using an LDH assay kit, and autophagosome in cells was observed by transmission electron microscopy. The level of autophagy in cells was detected through the mono-dansyl-cadaverine(MDC) detection method. Fluorescence quantitative polymerase chain reaction was used to detect the mRNA levels of miR-155, Notch1, Hes1, and microtubule-associated protein1 light chain 3(LC3), and Western blot was used to detect the protein expression levels of Notch1, Hes1, LC3Ⅰ, and LC3Ⅱ. The results show that after H/R injury, the activity of HL-1 cells decreases, and LDH leakage increases. Besides, the number of intracellular autophagosomes increases, and the mRNA level of LC3 and the LC3Ⅱ/LC3Ⅰ ratio are elevated. In addition, ginsenoside Rg_1 can increase cell activity, decrease LDH leakage and the number of intracellular autophagosomes, and reduce the mRNA level of LC3 and the LC3Ⅱ/LC3Ⅰ ratio. Therefore, it plays a cardioprotective role by inhibiting autophagy, and Notch1 inhibitor or miR-155 overexpression can inhibit the effect of ginsenoside Rg_1, promote autophagy, and aggravate H/R injury in HL-1 cells. Ginsenoside Rg_1 can inhibit the reduction of Notch1 and Hes1 mRNA levels and protein expressions and the increase in miR-155 mRNA levels caused by H/R injury, while Notch1 inhibitors or miR-155 overexpression show the opposite effect. In summary, ginsenoside Rg_1 can regulate autophagy through the miR-155/Notch1/Hes1 pathway to alleviate H/R injury in HL-1 cardiomyocytes.
