ObjectiveTo study the effects of applying different microbial fertilizers on the growth and rhizosphere soil environment of Codonopsis pilosula and provide a theoretical basis for ecological cultivation of this medicinal plant. MethodsSeven groups were designed， including CK （no application of microbial fertilizer）， T1 （Trichoderma longibrachiatum fertilizer）， T2 （Bacillus subtilis fertilizer）， T3 （Trichoderma viride fertilizer）， T4 （compound microbial fertilizer）， T5 （C. pilosula stems and leaves fermented with compound microbial fertilizer）， and T6 （Scutellaria baicalensis stems and leaves fermented with T. viride fertilizer）. The physiological indicators， yield， and quality of C. pilosula and the physicochemical properties， enzyme activities， and microbial diversity in the rhizosphere soil of different fertilizer treatments were measured. ResultsGroup T1 showed slight decreases in soluble protein content （SPC） and superoxide dismutase （SOD）. Groups T2-T6 showed increases in physiological indicators such as proline （Pro）， soluble solids content （SSC）， SPC， catalase （CAT）， and peroxidase （POD） and a decrease in malondialdehyde （MDA） in C. pilosula leaves. All the fertilizer treatments increased the yield of C. pilosula and the total polysaccharide content in the roots. T1， T2， T3， T4， and T5 increased the total flavonoid content in the roots. Meanwhile， T4 increased the total saponin content in the roots. All the fertilizer treatments reduced the pH and increased the electric conductivity （EC）， soil organic matter （SOM）， and alkaline nitrogen （AN） in the soil. T2 and T5 increased the available phosphorus （AP）， and T3， T4， T5， and T6 increased the available potassium （AK） in the soil. All the fertilizer treatments increased the activities of urease， sucrase， and CAT in the soil. Except that T1 decreased the bacterial diversity in the soil， other fertilizer treatments significantly increased bacterial and fungal diversity in the soil. Different fertilizer treatments significantly affected the composition of bacterial and fungal communities in the soil. At the phylum level， the dominant bacterial phyla included Proteobacteria， Acidobacteriota， and Bacteroideta， and the dominant fungal phyla were Ascomycota， Mortierellomycota， and unclassified_fungi in the rhizosphere soil of C. pilosula after bacterial fertilizer treatment. At the genus level， unclassified Gemmatimonadaceae， Sphingomonas， and unclassified Vicinamibacteraceae were the dominant bacterial genera， while unidentified， unclassified Fungi， and unclassified Sordariomycetes were the dominant fungal genera in the rhizosphere soil. The results of redundancy analysis indicated that the main physicochemical factors affecting changes of microbial communities in the rhizosphere soil of C. pilosula were pH， EC， AK， AN， AP， and soil organic matter （SOM） in the soil. The correlation heatmap showed that Bryobacter had significantly positive correlations with EC， AK， and AN. There was a significantly negative correlation between Fusarium and SOM. In summary， applying an appropriate amount of microbial fertilizer can promote the growth and improve the rhizosphere soil environment of C. pilosula. ConclusionThe compound microbial fertilizer and the C. pilosula stems and leaves fermented with compound microbial fertilizer can improve the soil nutrients， growth， development， yield， and quality of C. pilosula， and thus they can be applied to the artificial cultivation of C. pilosula.

The Huangdi Neijing proposes the " using bitter herbs to nourish or purge" theory to guide clinical prescription and formulation of herbal remedies based on the physiological characteristics and functions of the five zang viscera, along with the properties and flavors of medicinal herbs. This study explored diabetic kidney disease pathogenesis and treatment based on the " using bitter herbs to nourish or purge" theory. Kidney dryness is a key pathological factor in diabetic kidney disease, and the disharmony of kidney dryness is an essential aspect of its pathogenesis. Strengthening is the primary therapeutic principle, and kidney dryness is a persistent factor throughout the occurrence and progression of diabetic kidney disease. In the early stage, the pathogenesis involves heat-consuming qi and injuring yin, leading to kidney dryness. In the middle stage, the pathogenesis manifests as qi deficiency and blood stasis in the collaterals, resulting in turbidity owing to kidney dryness. In the late stage, the pathogenesis involves yin and yang deficiency, with kidney dryness and disharmony. This study proposes the staging-based treatment based on the " need for firmness" characteristic of the kidney. The aim is to provide new insights for clinical diagnosis and treatment in traditional Chinese medicine by rationally using pungent, bitter, and salty medicinal herbs to nourish and moisturize the kidney. This approach seeks to promote precise syndrome differentiation and personalized treatment for different stages of diabetic kidney disease, thereby enhancing clinical efficacy.

The paper summarizes Professor YANG Jun's thoughts on clinical treatment with acupuncture and moxibustion. Professor YANG Jun puts forward the "refined mode for diagnosis and treatment of diseases with acupuncture and moxibustion", aiming to improve the capacity of diagnosis and treatment in clinical practice. He advocates that the diagnosis and treatment should be guided by the identification of etiologies, syndromes and meridians; in accordance with regulating the shape/form, balancing yin and yang, and harmonizing the mind; and by means of skillful techniques of acupuncture and moxibustion, simplified selection of acupoints and delicate manipulations. Besides, he stresses on the combination of multiple techniques of acupuncture (such as penetrating technique with long needle, stuck needling by lifting and pulling, and micro-acupuncture systems) with moxibustion techniques (moxibustion for resolving stasis and unblocking collaterals, pressing moxibustion, borneol moxibustion, moxibustion with medicinal plaster) in clinical practice, so as to enhance the therapeutic effects.

eIF3a is a N ⁶-methyladenosine (m⁶A) reader that regulates mRNA translation by recognizing m⁶A modifications of these mRNAs. It has been suggested that eIF3a may play an important role in regulating translation initiation via m⁶A during infection when canonical cap-dependent initiation is inhibited. However, the death of animal model studies impedes our understanding of the functional significance of eIF3a in immunity and regulation in vivo. In this study, we investigated the in vivo function of eIF3a using eIF3a knockout and knockdown mouse models and found that eIF3a deficiency resulted in splenic tissue structural disruption and multi-organ damage, which contributed to severe sepsis induced by Lipopolysaccharide (LPS). Ectopic eIF3a overexpression in the eIF3a knockdown mice rescued mice from LPS-induced severe sepsis. We further showed that eIF3a maintains a functional and healthy immune system by regulating B cell function and quantity through m⁶A modification of mRNAs. These findings unveil a novel mechanism underlying sepsis, implicating the pivotal role of B cells in this complex disease process regulated by eIF3a. Furthermore, eIF3a may be used to develop a potential strategy for treating sepsis.

OBJECTIVE To compare the anti-thymic atrophy effects of petroleum ether(PEE), ethyl acetate(EAE), n-butanol(BE) and water extract(WE) fractions from root tubers of Tetrastigma hemsleyanum Diels et. Gilg based on mice thymic atrophy model established by intraperitoneal injection of PolyI:C to preliminarily investigate the mechanisms of its effects. METHODS One hunderd ICR mice were randomly divided into 10 groups: control group, model group, low- and high-dose groups of the four extract fractions, with 10 mice in each group. The control group and model group were given equal volume of purified water and gavaged for 10 d. Starting on the 9th day, PolyI:C solution of 16 mg·kg−1 was injected intraperitoneally for 2 consecutive days, except for the control group, which was injected intraperitoneally with physiological saline. Samples of thymics were weighed and and visceral index was calculated, blood samples were taken for analysis of IL-2, TNF-α and WBC, thymic histopathology was analyzed using hematoxylin-eosin staining, Western blotting was performed to detect the expression of TNF-α, p-NF-κB and NF-κB. RESULTS Compared with the model group, all groups of extracts could enhance the thymus weight and thymus index, as well as the cortex and medulla area ratio and the number of thymic corpuscles in 1 mm2 of medulla to different degrees, and at the same time, significantly reduce the level of TNF-α in plasma, evidently inhibited the phosphorylation of NF-κB, and reduced the protein expression of TNF-α, and each of them having distinct advantages and disadvantages. Peripheral blood white blood cell, lymphocyte absolute count and lymphocyte percentage were elevated in the low-dose WE group, low-dose EAE group and high dose PEE group, IL-2 levels were significantly elevated in the low-dose WE group and high dose BE group, and these effects were particularly well demonstrated. CONCLUSION Four extracts from root tubers of Tetrastigma Hemsleyanum Diels et. Gilg can improve morphological changes and atrophy of the thymus tissue in different degrees, regulate of peripheral blood leukocyte imbalance in post-modeling mice, it may be related to the inhibition of PolyI:C-induced phosphorylation of the NF-κB and reduction of protein expression of pro-inflammatory factors.

ObjectiveTo investigate the application of endoscopy in obtaining the great saphenous vein （GSV） during coronary artery bypass grafting （CABG） and explore the learning curve， with a particular focus on common challenges encountered during the learning process and their impact on early clinical outcomes. MethodsA retrospective analysis was conducted on clinical data from 83 patients who underwent off-pump CABG with endoscopic GSV harvesting at the First Affiliated Hospital of Zhengzhou University from July 2013 to April 2014. Patients were categorized into four groups based on the chronological order of their hospitalization： Group A （novice group， n=20）， Group B （proficient group， n=20）， Group C （progressive group， n=20）， and Group D （mature group， n=23）. Differences in perioperative and midterm follow-up outcomes among the groups were analyzed to determine the learning curve period. ResultsThe study population had a mean age of （60.22±8.06） years and a mean body weight of （69.77±11.66） kg. Comorbidities included hypertension （24 cases）， diabetes （26 cases）， and subacute cerebral infarction （14 cases）. The novice group exhibited significantly shorter GSV length-to-harvest time ratio relative to the other three groups （P<0.001） and a significantly higher incidence of main vein damage （P=0.006）. However， there was no statistically significant difference in graft patency at the 1-year follow-up. ConclusionThorough and reliable technical training in endoscopic GSV harvesting is essential to minimize vascular injury caused by novice operators. Approximately 20 cases of hands-on experience and a careful self-analysis of procedural challenges are likely required to achieve proficiency in GSV harvesting.

BACKGROUND:The proximal femoral nail antirotation is the preferred treatment for reverse osteoporotic intertrochanteric fractures.Bone cement enhancement can reduce the probability of proximal femoral nail antirotation cut-out and cut-through,but there are no relevant biomechanical studies demonstrating the effect of bone cement content and location on the stress and displacement of the fracture end. OBJECTIVE:To investigate the effects of different contents and locations of bone cement in cement-reinforced proximal femoral nail antirotation on stress,strain,and displacement of reverse osteoporotic femoral intertrochanteric fractures in the elderly by finite element analysis. METHODS:A healthy adult female right femur model was extracted by Mimics software and smoothed in Geometric software.Five types of internal fixation methods of proximal femoral nail antirotation(cementless,cephalic spherical 1 mL,cephalic spherical 2 mL,cephalic spherical 3.4 mL,and cylindrical 5 mL around spiral blade)and femoral intertrochanteric fracture(AO subtype 31-A3.1 type)model were established in Solidworks software.After assembly,the total stress distribution,peak stress and displacement of the five models of implants with the femur were compared in Ansys software. RESULTS AND CONCLUSION:(1)The peak stresses of proximal femoral nail antirotation with head-end spherical 1 mL,head-end spherical 2 mL,head-end spherical 3.4 mL,and cylindrical 5 mL enhanced proximal femoral nail antirotation around the spiral blade respectively were 571.07 MPa(located at the junction of the spiral blade and the main nail),495.45 MPa(located at the junction of the spiral blade and the main nail),467.20 MPa(located at the junction of the main nail and the distal screw connection),642.70 MPa(located at the junction of the main nail and distal screw connection),and 458.58 MPa(located at the junction of the spiral blade and the main nail).(2)The maximum displacements of proximal femoral nail antirotation with head end sphere 1 mL,head end sphere 2 mL,head end sphere 3.4 mL,and with cylindrical 5 mL enhancement around the spiral blade were 9.260 5,7.589 1,7.316 8,6.790 7,and 6.615 7 mm,respectively,all of which were located at the proximal end of the femoral head.(3)These findings revealed that for reverse femoral intertrochanteric fractures treated with proximal femoral nail antirotation,the bone cement enhancement had significant mechanical stability compared with no enhancement,and the enhancement of the spiral blade 5 mL around the perimeter was the best,which is more preferable for aged unstable intertrochanteric fractures.

BACKGROUND:Periprosthetic osteolysis is the most common long-term complication of total joint arthroplasty.Many studies suggest that the inflammasome may play an important role during the osteolysis.Melatonin is a rhythm-regulated hormone secreted by the pineal gland with many functions including anti-inflammatory,anti-oxidation,and antitumor,but its effects on osteolysis and inflammasome have yet to be explored. OBJECTIVE:To explore the effect of melatonin on the osteolysis induced by wear particles and the role of melatonin on the activation of NLRP3 inflammasome. METHODS:(1)In vivo test:Fifteen C57BL/6 mice were randomly divided into sham operation group,osteolysis group and melatonin group by random number table method,with 5 mice in each group.The osteolysis model of the osteolysis group and the melatonin group was established by injecting cobalt-chromium-molybdenum(CoCrMo)particles into the sagittal suture of the skull.After injection,the melatonin group was intraperitoneally injected with 50 mg/(kg·d)of melatonin for 14 consecutive days.After drug intervention,the mouse calvarium was collected for micro-CT analysis to observe the micro-structural changes around the sagittal suture.(2)In vitro test:Mouse bone marrow-derived macrophages and THP-1 cells(which had been induced to differentiate into macrophages)were taken and divided into seven groups:normal group,lipopolysaccharide group,lipopolysaccharide+CoCrMo group and melatonin 0.5,1,1.5,2 mmol/L groups(lipopolysaccharide and CoCrMo were added to the melatonin intervention groups).After the intervention for 6 hours,the expression of related proteins(NLRP3,Caspase-1,interleukin-1β,and gasdermin D,gasdermin D-N terminal)in the inflammasome of cell lysate or cell culture supernatant was detected by western blot assay.Cytotoxicity and cell death were observed through lactate dehydrogenase release and live-dead fluorescence staining. RESULTS AND CONCLUSION:(1)In vivo test:Micro-CT scanning 3D reconstruction images showed that the bone mass around the sagittal suture of the skull of mice in the osteolysis group was significantly reduced,and the bone tissue structure was severely damaged.Compared with the osteolysis group,the bone mass around the sagittal suture of the skull in the melatonin group was significantly increased,and the destruction of tissue structure was reduced.(2)In vitro test:For mouse bone marrow-derived macrophages,lipopolysaccharide significantly up-regulated NLRP3 protein expression in cell lysate,and melatonin intervention could reduce NLRP3 protein expression in a dose-dependent manner.CoCrMo particles significantly up-regulated the protein expressions of the gasdermin D-N terminal in cell lysate and Caspase-1 and interleukin-1β in the supernatant of cell culture,while melatonin intervention could reduce the expression of these proteins in a dose-dependent manner.For THP-1 cells,the protein expressions of Caspase-1 and interleukin-1β in the supernatant of cell culture were significantly up-regulated by CoCrMo particles,and the expression of these proteins was decreased dose-dependent by melatonin intervention.Lactate dehydrogenase release and live-dead fluorescence staining showed that CoCrMo particles significantly increased the release of lactate dehydrogenase and cell death in the supernatant of mouse bone marrow-derived macrophage culture,and melatonin intervention could reduce the release of lactate dehydrogenase and cell death.(3)The results show that melatonin can inhibit particle-induced inflammasome activation and pyroptosis to suppress periprosthetic osteolysis.
