ObjectiveBased on traditional quality evaluation of Gardeniae Fructus（GF） recorded in historical materia medica， this study systematically compared the quality differences between wild and cultivated GF from morphological characteristics， microscopic features， and contents of primary and secondary metabolites. MethodsVernier calipers and analytical balances were used to measure the length， diameter and individual fruit weight of wild and cultivated GF， and the aspect ratio was calculated. A colorimeter was used to determine the chromaticity value of wild and cultivated GF， and the paraffin sections of them were prepared by safranin-fast green staining and examined under an optical microscope to observe their microstructure. Subsequently， the contents of water-soluble and alcohol-soluble extracts of wild and cultivated GF were detected by hot immersion method under the general rule 2201 in volume Ⅳ of the 2020 edition of the Pharmacopoeia of the People's Republic of China， the starch content was measured by anthrone colorimetric method， the content of total polysaccharides was determined by phenol-sulfuric acid colorimetric method， the sucrose content was determined by high performance liquid chromatography coupled with evaporative light scattering detection（HPLC-ELSD）， and the contents of representative components in them were measured by ultra-performance liquid chromatography（UPLC）. Finally， correlation analysis was conducted between quality traits and phenotypic traits， combined with multivariate statistical analysis methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）， key differential components between wild and cultivated GF were screened. ResultsIn terms of traits， the wild GF fruits were smaller， exhibiting reddish yellow or brownish red hues with significant variation between batches. While the cultivated GF fruits are larger， displaying deeper orange-red or brownish red. The diameter and individual fruit weight of cultivated GF were significantly greater than those of wild GF， while the blue-yellow value（b^*） of wild GF was significantly higher than that of cultivated GF. In the microstructure， the mesocarp of wild GF contained numerous scattered calcium oxalate cluster crystals， while the endocarp contained stone cell class round， polygonal or tangential prolongation， undeveloped seeds were visible within the fruit. In contrast， the mesocarp of cultivated GF contained few calcium oxalate cluster crystals， or some batches exhibited extremely numerous cluster crystals. The stone cells in the endocarp were predominantly round-like， with the innermost layer arranged in a grid pattern. Seeds were basically mature， and only a few immature seeds existed in some batches. Regarding primary metabolite content， wild GF exhibited significantly higher total polysaccharide level than cultivated GF（P<0.01）. In category-specific component content， wild GF exhibited significantly higher levels of total flavonoids and total polyphenols compared to cultivated GF（P<0.01）. Analysis of 12 secondary metabolites revealed that wild GF exhibited significantly higher levels of Shanzhiside， deacetyl asperulosidic acid methyl ester， gardenoside and chlorogenic acid compared to cultivated GF（P<0.01）. Conversely， the contents of genipin 1-gentiobioside， geniposide and genipin were significantly lower in wild GF（P<0.01）. ConclusionThere are significant differences between wild and cultivated GF in terms of traits， microstructure， and contents of primary and secondary metabolites. At present， the quality evaluation system of cultivated GF remains incomplete， and this study provides a reference for guiding the production of high-quality GF medicinal materials.

ObjectiveTo construct a comprehensive evaluation indicator system for clinical practice guidelines of traditional Chinese medicine （TCM） that is scientific， systematic， and reflects the characteristics of TCM. MethodsA systematic search was conducted in Chinese and English databases， including CNKI， Wanfang， VIP， SinoMed， PubMed， Embase， and Cochrane Library， to include literature on domestic and international guideline evaluation tools and TCM-related research. Document analysis and CiteSpace were utilized for keyword co-occurrence and clustering analysis. ResultsA total of 65 relevant studies were included， from which seven core thematic domains were identified. Based on the research objectives， a two-step construction strategy was adopted： first， an external evaluation framework was established by referencing international tools to cover methodological rigor and procedural standardization； second， an internal evaluation framework was developed to reflect the distinctive features of TCM clinical practice， including syndrome differentiation and efficacy feedback. Through expert consensus， the indicator system was refined， resulting in a dual-layered structure comprising 8 primary indicators， 22 secondary indicators， and 62 evaluation criteria. ConclusionThe comprehensive evaluation system for TCM clinical practice guidelines， based on bibliometric analysis and core element extraction， integrates both theoretical integrity and practical applicability. This study provides a preliminary research foundation for further optimization， validation， and development of a refined comprehensive evaluation system.

Aging is an inevitable, physiological process of the human body, leading to deterioration in bodily function and increased susceptibility to various diseases. Effective endogenous therapeutic strategies for anti-aging and related diseases remain limited. Exercise confers multifaceted benefits to physical health by augmenting osteogenic and myogenic processes, enhancing cardiovascular and nervous system function, and attenuating chronic inflammation. Angiogenesis and lymphangiogenesis play pivotal roles in anti-aging, tissue repair, and immune response modulation, underscoring their potential as therapeutic targets for age-related diseases. Modulating angiogenic and lymphangiogenic pathways may provide a promising strategy for mitigating vascular decline and immune system dysfunction associated with aging. Exercise-induced endogenous angiogenesis and lymphangiogenesis can exert beneficial effects on physiological function, thereby representing a potential therapeutic paradigm for combating age-related decline and diseases. This review offers a thorough summary of the present knowledge regarding angiogenesis and lymphangiogenesis induced by exercise, encompassing the underlying mechanisms and the effects in different organs. In addition, it explores the potential of physical activity as a non-pharmacological intervention for anti-aging strategies and disease management, offering novel insights into the intersection of physical activity, aging, and disease progression.

OBJECTIVES: To explore the active components that mediate the therapeutic effect of Centella asiatica on psoriasis and their therapeutic mechanisms. METHODS: TCMSP, TCMIP, PharmMapper, Swiss Target Prediction, GeneCards, OMIM and TTD databases were searched for the compounds in Centella asiatica and their targets and the disease targets of psoriasis. A drug-active component-target network and the protein-protein interaction network were constructed, and DAVID database was used for pathway enrichment analysis. In a RAW264.7 macrophage model of LPS-induced inflammation, the anti-inflammatory effect of 7.5, 15, 30, and 60 μmol/L quercetin, asiaticoside, and asiatic acid, which were identified as the main active components in Centella asiatica, were tested by measuring cellular production of NO, TNF‑α and IL-6 using Griess method and ELISA and by detecting mRNA expressions of IL-23, IL-17A, TNF-α and IL-6 and protein expressions of p-STAT3 (Tyr705) and p-STAT3 (Ser727) with RT-qPCR and Western blotting. RESULTS: A total of 139 targets of Centella asiatica and 4604 targets of psoriasis were obtained, and among them CASP3, EGFR, PTGS2, and ESR1 were identified as the core targets. KEGG analysis suggested that quercetin, asiaticoside, and asiatic acid in Centella asiatica were involved in cancer and IL-17 and MAPK signaling pathways. In the RAW264.7 macrophage model of inflammation, treatment with quercetin significantly reduced cellular production of NO, TNF‑α and IL-6, and lowered mRNA expressions of IL-23, IL-17A, TNF‑α and IL-6 and protein expressions of p-STAT3 (Tyr705) and p-STAT3 (Ser727). CONCLUSIONS Quercetin, asiaticoside and asiatic acid are the main active components in Centella asiatica to mediate the therapeutic effect against psoriasis, and quercetin in particular is capable of suppressing cellular production of NO, TNF‑α and IL-6 and regulating the IL-23/IL-17A inflammatory axis by mediating STAT3 phosphorylation to inhibit inflammatory response.

Objective To investigate the effects of total flavonoids from Vine tea on the intestinal flora of high-fat diet(HFD)induced non-alcoholic fatty liver disease(NAFLD)mice.Methods Twenty-eight mice were randomly divided into four groups:blank control group,model control group(HFD group),low-dose TF group(TF-L group),and high-dose TF group(TF-H group),with 7 mice in each group.Mice in the HFD group,TF-L group,and TF-H group were fed with high-fat diet(HFD)for 12 weeks,while those in the blank control group were fed a normal diet.After 12 weeks of high-fat diet feeding,mice in the TF-L group and TF-H group were orally administered TF solution at doses of 125 and 250 mg·kg-1·d-1 by gavage administration for 6 weeks of intervention.Pathological changes in the liver and intestine of mice were observed using hematoxylin-eosin(H&E)staining,and the expression levels of tight junction proteins between the epithelial cells of the colonic mucosa was analyzed by immunohistochemistry.ELISA kit was used to detect the level of serum inflammatory factors in mice.Changes of intestinal flora in mice were analyzed by 16S rRNA sequencing technology.Results Total flavonoids from Vine tea could effectively improve the pathological changes of liver and intestinal tract in mice,reduce the levels of serum inflammatory factors IL-6 and TNF-α,and promote the expression of tight junction proteins Occludin,ZO-1 and Claudin 1 in the colon.There were significant differences in the intestinal flora of the three groups of mice.Total flavonoids from Vine tea significantly decreased the ratio of Firmicutes to Bacteroidota(P＜0.05),increased the abundance of Faecalibaculum,Ligilactobacillus and Lactobacillus,which resulted in the improvement of intestinal flora disorders.Conclusion Total flavonoids from Vine tea have certain ameliorative effects on high-fat diet-induced NAFLD,and the mechanism may be related to the promotion of intestinal barrier repair and the improvement of intestinal flora disorders.

Objective:To explore the current situation of organizational silence among emergency nurses and analyze its influencing factors, so as to provide a basis for interventions.Methods:From April to July 2023, convenience sampling was used to select 150 nurses from the Emergency Department of the First Affiliated Hospital of Air Force Military Medical University as the research subject. These subjects were surveyed using the General Information Questionnaire, Nurse Organizational Silence Evaluation Questionnaire and the Emotional Intelligence Scale. Pearson correlation was used to analyze the correlation between organizational silence and emotional intelligence among emergency nurses, and multiple linear regression was used to analyze the influencing factors of nurse organizational silence.Results:A total of 150 questionnaires were distributed, and 132 valid questionnaires were collected, with an effective response rate of 88.00% (132/150). The score of the Nurse Organizational Silence Evaluation Questionnaire of 132 emergency nurses was (60.83±13.52). The results of Pearson correlation analysis showed that there was a negative correlation between emotional intelligence and organizational silence in emergency nurses ( r=-0.410, P<0.01). Multiple linear regression analysis showed that gender, education level, work years, perceived economic level, and emotional intelligence were the influencing factors of organizational silence among emergency nurses ( P<0.05), which could explain 33.9% of the variation. Conclusions:Nursing managers should focus on nurses who are female and with low education levels, short working years, and low perceived economic levels, and provide training to improve their emotional intelligence, thereby reducing the level of organizational silence among emergency nurses.

Objective To evaluate the effectiveness of a 1470 nm semiconductor laser therapeutic instrument(referred to as a curestar therapeutic instrument)for prostatectomy in Beagle dogs.Methods Twenty-eight adult male Beagle dogs were randomly divided into three groups:sham(n=3),experimental(n=15),and control(n=10).The experimental group was further divided into three subgroups:120 W/50 W,150 W/50 W,and 160 W/50 W for vaporization cutting/coagulation hemostasis.The control group was divided into two subgroups:120 W/50 W and 150 W/50 W with five in each subgroup.Experimental and control groups underwent canine prostatectomy through the entrance of the bladder neck under electrocision.The operational suitability and effectiveness of the product during surgery were assessed.After the operation,the general condition of the dogs was observed,and blood biochemical and hematological indicators were measured before,immediately after,and at 3,7,and 28 days after the operation.At 1 h and 4 weeks after surgery,B-ultrasound and electric resection were performed under anesthesia to observe the conditions of the urethra and prostate,and prostatic tissue was subjected to HE staining for pathological observations.The thickness of the coagulation layer at 1 h after the operation and repair of the urothelial epithelium at 4 weeks were analyzed.Results During the operation,experimental and control groups had good operability and showed good vaporization cutting and coagulation hemostasis performance.After the operation,no significant effects were observed on the general condition,and blood biochemical and hematological indicators of the dogs.Ultrasound showed that the urethral expansion was visible immediately after the operation,and the echo of the urethral epithelium was slightly enhanced.At 4 weeks,the prostate tissue had a slightly low echo with uniformly distributed small point-like echoes inside,and the capsule had a linearly high echo,consistent with the sham group.The weight of the vaporized prostate tissue in experimental and control groups was 0.91～1.33 g with a resection rate of 17.11％～20.27％.As the power of vaporization cutting increased,the laser emission time gradually decreased,while the vaporization cutting speed and efficiency both increased.However,no significant difference was found between experimental and control groups(P＞0.05).Under the electrocision microscope,a burn-like change was observed in the surgical wounds of the prostate urethra in experimental and control groups at 1 h after surgery,and the boundary between the wound and normal urothelium was visible.At 4 weeks,the urothelium of the prostate had been repaired and flattened,and the boundary with the surrounding normal urothelium was blurred.Similarly,pathological observations showed that experimental and control groups had significant damage to the prostate urethral orifice at 1 h after surgery with a small amount of carbonization and coagulative necrosis on the surface of the wound,a small amount of inflammatory cell infiltration,and a coagulation layer thickness of approximately 0.4 mm.At 4 weeks,the prostate urethral morphology of the sham group was normal,whereas experimental and control groups showed new epithelial growth covering the wound with a uniform thickness and no coagulative necrosis tissue attached to the wound.A mild inflammatory reaction was still present in the surrounding area,fibroblast proliferation was obvious,and stromal and epithelial cell proliferation was visible in the surrounding prostate,some of which showed squamous metaplasia.The prostate capsule was intact and the morphology of the surrounding nerves and blood vessels was normal.Conclusions The curestar therapy instrument is effective for prostatectomy in Beagle dogs with good vaporization cutting and coagulation hemostasis performance.No significant difference was found in postoperative physiological indicators compared with the sham group.

Objective To observe MRI features of H3K27M mutant type and wild type astrocyte differentiated diffuse midline glioma(DMG)in spinal cord.Methods Totally 91 patients with astrocyte differentiation diffuse midline glioma(DMG)in spinal cord confirmed by pathology were retrospectively enrolled and divided into mutant group(n=44)and wild group(n=47)according to H3K27M status.Clinical and MRI manifestations were compared between groups,and logistic regression analysis was used to screen the impact factors of H3K27M mutation.Results The incidence of peritumoral edema and spinal cord cavity in mutant group were lower than those in wild group(both P＜0.05),while no significant difference of other parameters was found between groups(all P＞0.05).All clinical and MRI parameters were included in logistic regression analysis,and the result showed that they were not influencing factors of H3K27M mutation(all P＞0.05).Conclusion The incidence of peritumoral edema and spinal cord cavity in spinal cord H3K27M mutant type astrocyte differentiated DMG were lower than those of wild type,yet not sufficient to be regarded as impact factors for predicting H3K27M mutation of DMG.

Objective To summarize the best evidence of nutrition management in patients with severe pneumonia,aiming to offer evidence-based guidance for clinical healthcare professionals.Methods All evidence on nutrition management in patients with severe pneumonia was retrieved from various databases and websites including BMJ Best Practice,UpToDate,National Guideline Clearinghous(NGC),Guidelines International Network(GIN),Registered Nurses'Association of Ontario(RNAO),National Institute for Health and Care Excellence(NICE),Cochrane Library,OVID,PubMed,Embase,Web of Science,CINAHL,Chinese Medical Journal Full-text Database,CNKI,VIP,Wanfang,CBM,American Society for Parenteral and Enteral Nutrition(ASPEN),European Society for Clinical Nutrition and Metabolism(ESPEN),Society of Critical Care Medicine(SCCM)and European Society of Intensive Care Medicine(ESICM).The retrieved evidence included clinical decisions,guidelines,systematic reviews,expert consensuses and evidence summaries.The search period ranged from January 1st,2012 to December 31st,2022.There were 2 researchers who independently assessed the quality of the included studies and then extracted and summarized the evidence by topic.Results A total of 13 articles were involved,including 3 clinical decisions,4 guidelines,1 systematic review,and 5 expert consensuses.A total of 24 pieces of evidence were summarized across 6 aspects which encompassed team building,nutrition screening and assessment,nutritional requirements,nutrition intervention,nutrition monitoring,and health education.Conclusion The production process of this evidence summary followed standardized procedures,ensuring comprehensive content.Medical professionals should integrate clinical conditions,patient factors,and family preferences to select the most optimal evidence in order to enhance patient prognosis and improve medical quality.

Objective:To summarize the distributional characteristics of postoperative occurrence of multi-drug resistant organism (MDRO) infections and their risk factors in simultaneous pancreas-kidney transplantation (SPK) recipients and examine the impact of MDRO infections on the survival of SPK recipients.Method:From January 2016 to December 2022, the relevant clinical data were retrospectively reviewed for 218 SPK recipients. The source of donor-recipient specimens and the composition percentage of MDRO pathogens were examined. According to whether or not MDRO infection occurred post-transplantation, they were assigned into two groups of MDRO (98 cases) and non-MDRO (120 cases). The clinical data of two groups of donors and recipients were analyzed. And the risk factors for an onset of MDRO infection were examined by binary Logistic regression. The survival rate of two recipient groups was compared by Kaplan-Meier method.Result:A total of 98/218 recipients (45%) developed MDRO infections. And 46 (46.9%) of sputum and 34 (34.7%) of urine were cultured positively and 49 (50%) pathogens expressed extended spectrum beta-lactamase. There were pneumonia (46 cases, 46.9%), urinary tract infections (34 cases, 34.7%), abdominal infections (16 cases, 16.3%) and bloodstream infections (2 cases, 2.0%). Univariate regression analysis revealed that length of renal failure ( P=0.037), length of hospitalization ( P<0.001), length of antibiotic use ( P<0.001), novel antibiotics ( P=0.014), albumin ( P<0.001) and leukocyte count ( P<0.001) were risk factors for an onset of MDRO infections. The results of multifactorial regression indicated that low albumin ( OR=0.855, 95% CI: 0.790~0.925, P<0.001) and leukopenia ( OR=0.656, 95% CI: 0.550~0.783, P<0.001) were independent risk factors for an onset of MDRO infections. The survival rates of recipients in MDRO group at Year 1/3 post-operation were 92.9% (91/98) and 89.8% (88/98). And the survival rate of recipients in non-MDRO group was 96.7% (116/120) at Year 1/3 post-operation. Inter-group difference was not statistically significant in 1-year survival rate of two recipient groups ( P=0.201); statistically significant inter-group difference in 3-year survival rate between two recipient groups ( P=0.041) . Conclusion:Low albumin and leukopenia are risk factors for MDRO infection. Infection with MDRO has some impact on the survival of recipients.
