ObjectiveTo explore the spatial distribution patterns of flavonoid glycosides in Epimedium sagittatum and the influences of environmental factors on the accumulation of these components. MethodsThe spatial statistical analysis and GeoDetector model were used to analyze the distribution patterns of epimedin A,epimedin B,epimedin C,icariin,and total flavonoid glycosides in E. sagittatum samples from 92 different production areas in 36 cities of 13 provinces/municipalities/autonomous regions of China,as well as the effects of 28 environmental factors on the accumulation of each component. ResultsThe average content of flavonoid glycosides 64 (69.56%) producing areas and 30 (83.33%) cities met the quality standard of no less than 1.50% of total flavonoid glycosides in the 2020 edition of Chinese Pharmacopoeia.Epimedin A,epimedin B,epimedin C,icariin,and their sum showed significantly high accumulation.The hot spots regions of epimedin A and epimedin B were similar with each other,mainly located in western Hunan,eastern Hubei,eastern Guizhou,and northern Guangxi.The common hot spot areas of epimedin C and total flavonoid glycosides were in western and southwestern Hunan,southern Henan,northern Anhui,eastern Guizhou,and southern Chongqing.The hot spots areas of icariin were in southern Chongqing,western Hunan,and eastern and northeastern Guizhou.The interactions between environmental factors had stronger explanatory power for the accumulation of components than single factors.The strongest single factor and interactive factor affecting the accumulation of epimedin C were precipitation of wettest quarter (q=0.16) and its interaction with temperature seasonality (q=0.35),respectively.The strongest single factor influencing both the accumulation of icariin and total flavonoid glycosides was the precipitation of coldest quarter (q equals 0.15 and 0.22,respectively).The strongest interactions were observed between precipitation of coldest quarter and gravel content (q=0.34),as well as between precipitation of coldest quarter and aspect (q=0.35). ConclusionThirteen cities,including Zhumadian and Nanyang in Henan,Huaihua,Shaoyang,and Zhangjiajie in Hunan,and Zunyi,Qiandongnan,and Tongren in Guizhou,were hot spots of total flavonoid glycosides in E.sagittatum.Precipitation,gravel content,temperature seasonality,and aspect significantly influence the accumulation of flavonoid glycosides in E.sagittatum.This study provides reference for the utilization and production zoning of E.sagittatum.

ObjectiveTo study the regulatory effects of Yinchenhao Tang combined with Yinchen Zhufu Tang on the expression of regulatory T (Treg)/helper T 17 (Th17) cells cultured in vitro from the patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). MethodsFresh peripheral blood was collected from the patients with HBV-ACLF for the separation of peripheral blood mononuclear cells (PBMCs). Immunomagnetic beads were used to isolate primary Treg and naive CD4+ T cells. After in vitro expansion, naive CD4+ T cells were induced to differentiate into Th17 cells. Rats were treated with the clearing method (Yinchenhao Tang), warming method (Yinchen Zhufu Tang), and combination of clearing method with warming method (Yinchenhao Tang combined with Yinchen Zhufu Tang, also known as Wenyang Jiedu Huayu Prescription), respectively, and then the medicated plasma samples were collected. Meanwhile, blank plasma was collected from the rats treated with normal saline. Cells were classified into blank, clearing method (5.04 g·kg-1), warming method (6.21 g·kg-1), and combination of clearing method with warming method (17.1 g·kg-1) groups and treated with corresponding plasma. The frequency of Treg/Th17 cells was detected by flow cytometry. The level of transforming growth factor-β (TGF-β) was measured by the enzyme-linked immunosorbent assay. The cytometric bead array (CBA) was employed to measure the levels of interleukin-10 (IL-10), interleukin-17A (IL-17A), tumor necrosis factor-α (TNF-α), and interleukin-23 (IL-23). The mRNA and protein levels of Forkhead box P3 (FoxP3) and retinoic acid-related orphan receptor-gamma t (ROR-γt) were determined by Real-time PCR and Western blot, respectively. ResultsCompared with the blank group, the combination of clearing method with warming method group showed decreased frequency of Treg and Th17 cells, lowered levels of Treg cytokines (TGF-β and IL-10) and Th17 cytokines (TNF-α, IL-17A, and IL-23), and down-regulated mRNA and protein levels of FoxP3 and ROR-γt (P<0.01). Compared with the clearing method group, the combination of clearing method with warming method group showed decreased Treg cell frequency and down-regulated mRNA and protein levels of FoxP3. Meanwhile, the combination group showed decreased Th17 cell frequency, lowered levels of TGF-β, IL-10, TNF-α, IL-17A, and IL-23, and down-regulated mRNA and protein levels of ROR-γt (P<0.05, P<0.01). Compared with the warming method group, the combination of clearing method with warming method group showed decreased frequency of Treg cells and down-regulated mRNA and protein levels of FoxP3. Meanwhile, the combination group showed decreased Th17 cell frequency, declined levels of TGF-β, IL-10, TNF-α, IL-17A, and IL-23, and down-regulated mRNA and protein levels of ROR-γt (P<0.05). ConclusionThe combination of clearing method with warming method can down-regulate the expression of specific cytokines of Treg and Th17 cells, inhibit the over activation of Treg and Th17 cells, and reduce the secretion of cytokines such as TGF-β, IL-10, TNF-α, IL-17A, and IL-23, thereby alleviating inflammation and improving the prognosis of the patients with liver failure.

ObjectiveTo investigate the differential expression of intestinal flora in patients with different traditional Chinese medicine (TCM) syndrome types (Yang Huang syndrome, Yin-Yang Huang syndrome, and Yin Huang syndrome) of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) and clarify the biological basis of jaundice and Yin Huang syndrome in liver failure. MethodsA total of 20 cases of HBV-ACLF patients were included in the Yang Huang group, 20 cases in the Yin-Yang Huang group, 16 cases in the Yin Huang group, and 20 healthy adult volunteers. 16S rRNA gene sequencing was used to detect the diversity, species distribution, and differences of the subjects' intestinal flora, and bioinformatics analysis was conducted. ResultsCompared with those in the healthy control group, the species richness and diversity of intestinal flora in the HBV-ACLF Yang Huang group, Yin-Yang Huang group, and Yin Huang group were significantly reduced, and there were significant differences in the composition of intestinal flora compared with healthy volunteers. However, there were no significant differences in the species richness, diversity, and composition of intestinal flora among the three groups. LEfSe analysis showed that compared with the healthy control group, the HBV-ACLF Yang Huang group showed significant enrichment of Staphylococcus aureus(P<0.01). Yin-Yang Huang group showed significant enrichment of s_Ileibacterium valens(P<0.05,P<0.01), and the Yin Huang group showed significant enrichment of Enterococcus faecium and Streptococcus sali varius(P<0.05). These strains may be biomarkers between the three groups of patients and the healthy control group. Compared with that in the Yin-Yang Huang group, Tyzzerella_nexilis was significantly enriched in the Yang-Huang group, and Streptococcus lactiae was significantly enriched in the Yin-Yang Huang group. Compared with that in the Yang-Huang group and the Yin-Yang Huang group, Enterococcus faecalis was significantly enriched in the Yin Huang group. The above strains may be biomarkers among the three groups of patients, and Enterococcus faecium may be a biomarker for the transition from the Yang Huang group to the Yin Huang group. ConclusionsThere are significant differences in the intestinal flora between patients with HBV-ACLF Yang Huang syndrome, Yin-Yang Huang syndrome, and Yin Huang syndrome. Enterococcus faecium is significantly enriched in the Yin Huang syndrome group, suggesting that dysbiosis of the intestinal flora may be the biological basis for jaundice and Yin Huang syndrome in liver failure.

BACKGROUND:As the incidence of spinal cord injury increases with the years and axon regeneration after spinal cord injury was very difficult.How to promote the recovery from spinal cord injury and improve the transplantation efficiency of stem cells and other therapeutic cells after spinal cord injury has been the focus of clinical and scientific research. OBJECTIVE:To establish the efficient transplantation and replacement of mouse spinal cord microglia in the spinal cord injury model. METHODS:CX3CR1 creER-/+::LSL-BDNF-/+-tdTomato mice,CX3CR1+/GFP mice,β-actin GFP mice and C57 BL/6J wild-type mice at 8-10 weeks of age were selected.According to the requirements of the experiment,they were randomly divided into six groups.(1)Sham operation group:eight C57 BL/6J wild-type mice were used when only the lamina was removed without injury.(2)Spinal cord contusion injury group:eight C57 BL/6J wild-type mice were used.(3)Spinal cord crush injury group:eight C57 BL/6J wild-type mice were used.(4)Conjoined symbiotic spinal cord strike injury group:β-actin GFP mice with green fluorescent blood were surgically stitched together with C57 BL/6J wild-type mice,using eight β-actin GFP mice and eight C57 BL/6J wild-type mice.(5)Mr BMT-X Ray group(using PLX5622 to eliminate the spinal microglia and bone marrow transplantation with X-ray radiation):Bone marrow cells from four CX3CR1 creER-/+::LSL-BDNF-/+-tdTomato mice were extracted and transplanted into eight C57 BL/6J wild-type mice for spinal cord injury modeling.(6)Mr BMT-Busulfan group(using PLX5622 to eliminate the spinal microglia and bone marrow transplantation with Busulfan):Bone marrow cells from four CX3CR1+/GFP mice were transplanted into eight C57 BL/6J wild-type mice.The percentage of cell transplantation replacement in this group was observed,and the spinal cord injury model was not established in this group.The sham operation group,spinal cord contusion injury group and spinal cord crush injury group were sampled by perfusion on day 14 after spinal cord injury.The conjoined symbiotic spinal cord strike injury group was sampled by perfusion on day 7 after spinal cord injury.Mr BMT-X Ray group was sampled by perfusion on day 28 after spinal cord injury.Mr BMT-Busulfan group was sampled by perfusion on day 28 after transplantation.The sampling site was a 1.2 cm long spinal cord with the T10 segment as the center.In the Mr BMT-X Ray group and Mr BMT-Busulfan group,additional mouse brain tissue was retained to see if it would lead to brain transplantation and replacement.The number and proportion of transplanted and replaced cells in the damaged area were measured using transgenic mice,symbiosis and immunofluorescence. RESULTS AND CONCLUSION:Compared with the traditional peripheral blood transplantation(9.8%)of mice in the conjoined symbiotic spinal cord strike injury group,the new transplantation methods,Mr BMT-X Ray and Mr BMT-Busulfan,could greatly improve the proportion of spinal microglia transplantation and replacement,which could reach 84.8%and 95.6%,respectively.The difference was significant(P<0.05).The results showed that Mr BMT-X Ray and Mr BMT-Busulfan could achieve efficient replacement of spinal microglia cells,and could improve the problems of low cell transplantation efficiency,few survival numbers and unclear differentiation of the traditional cell transplantation methods.In addition,Mr BMT-X Ray can only replace the microglia in the spinal cord,while Mr BMT-Busulfan could avoid brain inflammation and injury caused by X-ray radiation transplantation.

[Objective] To summarize the diagnosis and treatment of Antopol Goldman lesion (AGL) in clinical practice. [Methods] Clinical data and diagnosis and treatment process of one AGL case treated in our hospital were retrospectively analyzed, and relevant literature was reviewed. [Results] The patient presented with painless gross hematuria and right-sided lower back pain.Imaging examination suggested swelling of the right kidney, blood accumulation in the right calyx, renal pelvis and lower ureter, blood clot in the bladder, and multiple small stones in the left kidney.After multidisciplinary consultation, close imaging follow-up, interventional and flexible ureterdscope examination, tumors of hematological diseases, renal hematuria, arteriovenous fistula and collection system were excluded.After conservative treatment, the patient gradually recovered.During the follow-up of 1 year, no hematuria or low back pain recurred. [Conclusion] There is no clear diagnostic standard for AGL.Diagnosis relies on imaging, interventional methods and ureteroscopy.It is necessary to exclude other diseases and adopt conservative treatment.

Objective:To design a virtual simulation tutorial system for bone traction nursing of the lower limbs, and to investigate its application effect.Methods:Based on clinical cases, a 3D model was established for the fractured lower limb using the virtual simulation technique. The design of the model considered the position and mechanical relationship between bone traction and fracture ends, as well as the assessment and intervention of the condition after bone traction, and such factors were taken as the core elements of simulation design. Virtual experiments were conducted for the four scenarios of pre-hospital first aid, triage in the hospital, bone traction operation, and postoperative nursing. Such experiments were conducted among junior nursing undergraduates, and examination results and student satisfaction survey were used to evaluate the application effect of the experiments.Results:The teaching software consisted of four training modules, i.e., theoretical knowledge learning of fractures, preparation before bone traction operation, methods and principles of bone traction operation, and observation of conditions after bone traction. The final score of experiments was (90.99±0.58) points among the students, and the degree of satisfaction with the experimental system and the teaching model was 87.85% (441/502) and 63.35% (318/502), respectively.Conclusions:The virtual simulation experiments for bone traction nursing of the lower limbs are scientific, professional, and interesting and have a relatively high degree of satisfaction among students, and therefore, they can be applied in the education of nursing students and the continuing education of nurses.

Objective:To explore the current situation of fear of progression among parents of school-age children with asthma, and to analyze the latent profile categories and influencing factors, so as to provide the reference for the formulation of prevention and intervention.Methods:Using convenient sampling method, school-age children with asthma and their parents treated in the Affiliated Children's Hospital of Xiangya School of Medicine, Central South University from March to August 2023 were selected as the study objects. The General Data Questionnaire, Parent Fear of Progression Scale, Childhood Asthma Control Test, and Social Support Rating Scale were used to investigate school-age children with asthma and their parents. Latent profile analysis was performed on the fear of disease progression among parents of school-age children with asthma, and χ2 test and binary Logistic regression were used to explore the influencing factors. Results:A total of 210 parents of the children were included with 51 fathers and 159 mothers.The age distribution was 20-30 years old with 42 parents, 31-40 years old with 112 parents, 41-50 years old with 56 parents. In 210 children with asthma, there were 123 males and 87 females, with 141 cases aged<10 years old and 69 cases aged ≥10 years old. The fear of progression among parents of school-age children with asthma could be divided into two potential profile categories: "psychological dysfunction group (46.7%, 98/210)" and "psychological health good group (53.3%, 112/210)". The results of binary Logistic regression analysis showed that asthma family history, combined allergic rhinitis, child-parent relationship, marital status, asthma symptom control level, and social support level were the influencing factors of fear of progression among parents of school-age children with asthma( OR values were 0.925-10.010, all P<0.05). Conclusions:The fear of progression among parents of school-age children with asthma is at a moderate level, and there are obvious different classification characteristics. In the future, targeted and precise prevention and intervention should be implemented according to the category characteristics of fear of progression among parents of school-age children with asthma.

Objective:To explore the magnetic resonance imaging (MRI) features and classification of intraductal papillary neoplasm of the bile duct (IPNB).Methods:Data from 90 patients with intraductal papillary neoplasm of the bile duct confirmed pathologically between June 2010 and January 2023 were retrospectively analyzed. The image analysis included the shape and location of the tumor, whether bile ducts had dilatation and the degree of dilation, whether there was a history of liver disease, whether there was a history of schistosomiasis, whether there was cancerous transformation, whether there were concurrent bile duct stones, whether there was hepatic lobe atrophy, whether there was hilar or abdominal lymph node enlargement, whether there was invasion of the bile duct wall, whether there was invasion of surrounding blood vessels, whether the tumor appears on T1-and T2 weighted imaging (T 1WI and T 2WI), whether the diffusion was limited, whether there was concurrent bleeding, enhancement rate, and whether there was abdominal fluid accumulation. Intraductal papillary neoplasms of the bile duct were divided into four types according to the morphological classification standards: type I (local bile duct dilation), type II (cystic), type III (free tumor), and type IV (dilated bile duct). The differences in the clinical and MRI features of the four groups of lesions were analyzed. Statistical analysis was performed with a t-test, an analysis of variance, and an χ2-test according to the different data. Results:Among the 90 cases with hepatic IPNB, there were 31 cases of type I, 15 cases of type II, 16 cases of type III, and 28 cases of type IV, 41 cases of liver left lobe, 11 cases of right and left lobe liver span, 7 cases of liver right lobes, 2 cases of liver caudate lobe, and 13 cases of hepatic hilar. There were statistically significant differences between the four groups ( P ?0.05) in terms of age, clinical symptoms, direct bilirubin, γ-glutamyltransferase, whether they were cancerous, whether they were combined with bile duct stones, whether the liver lobes were atrophying, whether there was limited diffusion, intrahepatic bile duct diameter, and common bile duct diameter. However, there were no statistically significant differences among the four groups in gender, location, carbohydrate antigen 19-9, history of liver disease, history of schistosomiasis, carcinoembryonic antigen, alanine aminotransferase, aspartate aminotransferase, total bilirubin, whether hemorrhage was associated, lesion enhancement rate, whether the hilar/retroperitoneal lymph node was enlarged, whether the bile duct wall was invaded, whether blood vessels were invaded, and whether abdominal fluid was accumulated ( P ?>?0.05). Conclusion:MRI manifestations have certain features for different types of intraductal papillary neoplasm of the bile duct tumors; hence, MRI aids in the diagnosis and differential diagnosis of this disease.

To investigate the therapeutic effect of open reduction and internal fixation (ORIF) on supination external rotation (SER) ankle fractures (AF) and its impact on ankle joint function and range of motion in patients.Methods:The observation group patients were treated with ORIF, while the control group patients were treated with manual reduction combined with plaster external fixation. Both groups of patients were followed up after 3 and 6 months of treatment. Compare the ankle joint function levels of two groups of patients before treatment and after 3 and 6 months of treatment (Kofood score, AOFAS score, Olerud Molander subjective ankle score (OMAS)). Compare the joint range of motion (relative peak force, torque acceleration energy, endurance) between two groups of patients after 3 and 6 months of treatment. Compare the clinical indicators and incidence of adverse events between two groups of patients after 6 months of treatment. T-test was used for comparison between two groups. Multiple group comparisons were conducted using analysis of variance, while pairwise comparisons were conducted using Dunnett-t test. Comparison of count data between groups using χ2 inspections or Fisher exact test. Results:Before treatment, there was no statistically significant difference in the Kofoed score, AOFAS score, and OMAS score between the two groups of patients (all P>0.05). The Kofoed scores of patients in the observation group before treatment and at 3 and 6 months of treatment were (53.78±6.40), (76.73±4.12), and (89.07±5.78) points, respectively. The control group was (52.22±7.08), (71.68±4.82), and (84.05±5.45) points, respectively. The Kofoed scores of patients in both groups were higher than before treatment at 3 and 6 months of treatment (all P<0.05), and the observation group was higher than the control group (all P<0.01).The AOFAS scores of patients in the observation group before treatment and at 3 and 6 months of treatment were (70.13±5.39), (81.62±4.25), and (92.05±4.15) points, respectively. The control group was (69.85±5.41), (79.08±4.60), and (88.92±4.43) points, respectively. The AOFAS scores of patients in both groups were higher than before treatment at 3 and 6 months of treatment (all P<0.05), and the observation group was significantly higher than the control group (all P<0.01).The OMAS scores of the observation group patients before treatment and at 3 and 6 months of treatment were (53.43±5.07), (76.14±4.52), and (85.68±4.14) points, respectively. The control group was (54.42±4.86), (71.39±3.94), and (81.78±4.15) points, respectively. The OMAS scores of the two groups of patients at 3 and 6 months of treatment were higher than before treatment (all P<0.05), and the observation group was higher than the control group (all P<0.01). The fracture healing time (38.85±4.50) days and complete weight-bearing time (66.62±7.14) days of the observation group patients were shorter than those of the control group patients (49.42±5.43) days and (74.39±6.75) days, and the differences between the two groups were statistically significant (t-values were 12.89 and 6.80, respectively, all P<0.01); There was no statistically significant difference in the incidence of adverse events between the two groups of patients (5.41% (4/74) and 9.46% (7/74)), χ2=0.88, P=0.347). Conclusion:ORIF has a good therapeutic effect on SER-AF patients, promotes ankle joint function recovery, and has a low incidence of adverse events, indicating good safety.
