Evaluation of hemostatic, anti-inflammatory, wound healing, skin irritation and allergy, and antimicrobial properties of active fraction from the ethanol extract of Chromolaena odorata (L.) R.M. King & H. Rob.

ETHNOPHARMACOLOGICAL RELEVANCE: Chromolaenaodorata (L.) R.M. King & H. Rob, a perennial herb, has been traditionally utilized as a herbal remedy for treating leech bites, soft tissue wounds, burn wounds, skin infections, and dento-alveolitis in tropical and subtropical regions. AIM OF THE STUDY: The present study was to analyze the active fraction of C. odorata ethanol extract and investigate its hemostatic, anti-inflammatory, wound healing, and antimicrobial properties. Additionally, the safety of the active fraction as an external preparation was assessed through skin irritation and allergy tests. MATERIALS AND METHODS: The leaves and stems of C. odorata were initially extracted with ethanol, followed by purification through AB-8 macroporous adsorption resin column chromatography to yield different fractions. These fractions were then screened for hemostatic activity in mice and rabbits to identify the active fraction. Subsequently, the hemostatic effect of the active fraction was assessed through the bleeding time of the rabbit ear artery in vivo and the coagulant time of rabbit blood in vitro. The anti-inflammatory activity of the active fraction was tested on mice ear edema induced by xylene and rat paw edema induced by carrageenin. Furthermore, the active fraction's promotion effect on wound healing was evaluated using a rat skin injury model, and skin safety tests were conducted on rabbits and guinea pigs. Lastly, antimicrobial activities against two Gram-positive bacteria (G+, Staphylococcus aureus and S. epidermidis) and three Gram-negative bacteria (G-, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa) were determined using the plate dilution method. RESULTS: The ethanol extract of C. odorata leaves and stems was fractionated into 30%, 60%, and 90% ethanol eluate fractions. These fractions demonstrated hemostatic activity, with the 30% ethanol eluate fraction (30% EEF) showing the strongest effect, significantly reducing bleeding time (P < 0.05). A concentration of 1.0 g/mL of the 30% EEF accelerated cutaneous wound healing in rats on the 3rd, 6th, and 9th day post-operation, with the healing effect increasing over time. No irritation or allergy reactions were observed in rabbits and guinea pigs exposed to the 30% EEF. Additionally, the 30% EEF exhibited mild inhibitory effect on mice ear and rat paw edema, as well as antimicrobial activity against tested bacteria, with varying minimal inhibitory concentration (MIC) values. CONCLUSIONS: The 30% EEF demonstrated a clear hemostatic effect on rabbit bleeding time, a slight inhibitory effect on mice ear edema and rat paw edema, significant wound healing activity in rats, and no observed irritation or allergic reactions. Antibacterial activity was observed against certain clinically isolated bacteria, particularly the G- bacteria. This study lays the groundwork for the potential development and application of C. odorata in wound treatment.

Green synthesis of silver nanoparticles using Phlebopus portentosus polysaccharide and their antioxidant, antidiabetic, anticancer, and antimicrobial activities.

Silver nanoparticles (AgNPs) by green synthesis from fungi polysaccharides are attracting increasing attention owing to their distinctive features and special applications in numerous fields. In this study, a cost-effective and environmentally friendly biosynthesizing AgNPs method with no toxic chemicals involved from the fruiting body polysaccharide of Phlebopus portentosus (PPP) was established and optimized by single factor experiment and response surface methodology. The optimum synthesis conditions of polysaccharide-AgNPs (PPP-AgNPs) were identified to be the reaction time of 140 min, reaction temperature of 94 °C, and the PPP: AgNO3 ratio of 1:11.5. Formation of PPP-AgNPs was indicated by visual detection of colour change from yellowish to yellowish brown. PPP-AgNPs were characterized by different methods and further evaluated for biological activities. That the Ultraviolet-visible (UV-Vis.) spectroscopy displayed a sharp absorption peak at 420 nm confirmed the formation of AgNPs. Fourier transform infrared (FTIR) analysis detected the presence of various functional groups. The lattice indices of (111), (200), (220), and (331), which indicated a faced-centered-cubic of the Ag crystal structure of PPP-AgNPs, was confirmed by X-ray diffraction (XRD) and the particles were found to be spherical through high resolution transmission electron microscopy (HRTEM). Energy dispersive X-ray spectroscopy (EDS) determined the presence of silver in PPP-AgNPs. The percentage relative composition of elements was determined as silver (Ag) 82.5 % and oxygen (O) 17.5 % for PPP-AgNPs, and did not exhibit any nitrogen peaks. The specific surface area of PPP-AgNPs was calculated to be 0.5750 m2/g with an average pore size of 24.33 nm by BET analysis. The zeta potential was -4.32 mV, which confirmed the stability and an average particle size of 64.5 nm was calculated through dynamic light scattering (DLS). PPP-AgNPs exhibited significant free radical scavenging activity against DPPH with an IC50 value of 0.1082 mg/mL. The MIC values of PPP-AgNPs for E. coli, S. aureus, C. albicans, C. glabrata, and C. parapsilosis are 0.05 mg/mL. The IC50 value of the inhibition of PPP-AgNPs against α-glucosidase was 11.1 µg/mL, while the IC50 values of PPP-AgNPs against HepG2 and MDA-MB-231 cell lines were calculated to be 14.36 ± 0.43 µg/mL and 40.05 ± 2.71 µg/mL, respectively. According to the evaluation, it can be concluded that these green-synthesized and eco-friendly PPP-AgNPs are helpful to improve therapeutics because of significant antioxidant, antimicrobial, antidiabetic, and anticancer properties to provide new possibilities for clinic applications.

Clinical characteristics and prognosis of 28 cases of infant acute lymphoblastic leukemia / 中华儿科杂志

Objective: To analyze the clinical characteristics and prognosis of patients with infant acute lymphoblastic leukemia (IALL). Methods: A retrospective cohort study.Clinical data, treatment and prognosis of 28 cases of IALL who have been treated at Beijing Children's Hospital, Capital Medical University and Baoding Children's Hospital from October 2013 to May 2023 were analyzed retrospectively. Based on the results of fluorescence in situ hybridization (FISH), all patients were divided into KMT2A gene rearrangement (KMT2A-R) positive group and KMT2A-R negative group. The prognosis of two groups were compared. Kaplan-Meier method and Log-Rank test were used to analyze the survival of the patients. Results: Among 28 cases of IALL, there were 10 males and 18 females, with the onset age of 10.9 (9.4,11.8) months. In terms of immune classification, 25 cases were B-ALL (89%), while the remaining 3 cases were T-ALL (11%). Most infant B-ALL showed pro-B lymphocyte phenotype (16/25,64%). A total of 22 cases (79%) obtained chromosome karyotype results, of which 7 were normal karyotypes, no complex karyotypes and 15 were abnormal karyotypes were found. Among abnormal karyotypes, there were 4 cases of t (9; 11), 2 cases of t (4; 11), 2 cases of t (11; 19), 1 case of t (1; 11) and 6 cases of other abnormal karyotypes. A total of 19 cases (68%) were positive for KMT2A-R detected by FISH. The KMT2A fusion gene was detected by real-time PCR in 16 cases (57%). A total of 24 patients completed standardized induction chemotherapy and were able to undergo efficacy evaluation, 23 cases (96%) achieved complete remission through induction chemotherapy, 4 cases (17%) died of relapse. The 5-year event free survival rate (EFS) was (46±13)%, and the 5-year overall survival rate (OS) was (73±10)%.The survival time was 31.3 (3.3, 62.5) months. There was no significant statistical difference in 5-year EFS ((46±14)% vs. (61±18)%) and 5-year OS ((64±13)% vs. (86±13)%) between the KMT2A-R positive group (15 cases) and the KMT2A-R negative group (9 cases) (χ2=1.88, 1.47, P=0.170, 0.224). Conclusions: Most IALL patients were accompanied by KMT2A-R. They had poor tolerance to traditional chemotherapy, the relapse rate during treatment was high and the prognosis was poor.

T Cell Invigoration is Associated with the Clinical Response to Anti-PD-1-Based Immunotherapy in Non-Small Cell Lung Cancer.

Purpose: Immune checkpoint inhibitors (ICIs) have been developed for clinical application and proven effective for non-small cell lung cancer (NSCLC). Blockade of the programmed cell death 1 (PD-1) protein can partially reinvigorate circulating exhausted-phenotype CD8+ T cells (Tex cells) in preclinical models, however the clinical implication in anti-PD-1-based immunotherapy in NSCLC is unknown. Methods: Serum specimens were obtained before and during treatment from 145 patients with NSCLC patients who received anti-PD-1 treatment and their prognoses were followed-up. Indicators such as cell subpopulations, T cell invigoration were detected by clinical laboratory testing. Survival curves were estimated by the Kaplan-Meier method, Cox regression analysis was used to identify factors associated with prognoses of NSCLC patients. Results: The expressions of Ki-67 in PD-1+/CD8+ T cells in most NSCLC patients (97 of 145 cases) increased after treatment. The responding Ki-67+/CD8+ T cell population was mainly CD45RAlo CD27hi, containing cells with high expression of CTLA-4, PD-1, and 2B4 and low expression of NKG2-D (P < 0.0001). The maximum fold change of Ki-67+/PD-1+/CD8+T cells in treatment cycles and the tumor burden determined by imaging may be associated with survival. Patients with higher Ki-67 expression on PD-1+CD8+ T-cells (pretreatment) had statistically significant increased progression-free survival (PFS). A Ki-67 expression to tumor burden ratio greater than 0.6 at the 1st cycle of anti-PD-1 immunotherapy was associated with improvement of PFS and overall survival (P < 0.05). Conclusion: Activation of circulating Tex cells before or during therapy related to tumor burden may be associated with clinical efficacy of anti-PD-1 immune therapy in NSCLC.

Extraction, Characterization, and In Vitro Hypoglycemic Activity of a Neutral Polysaccharide from the New Medicinal Mushroom Cantharellus yunnanensis (Agaricomycetes).

Polysaccharides serve as promising ingredients for health-beneficial functional foods, while there were no investigations into the structural characterizations and bioactivities of an edible mushroom Cantharellus yunnanensis. In the study, crude polysaccharides from this mushroom were extracted by hot water and isolated by ethanol precipitation. Then, a neutral polysaccharide (named CY-1) was purified from the crude polysaccharide by deproteinization with Sevag reagent, decolorization with a kind of macroporous adsorption resin SP-825, DEAE-52 cellulose column chromatography and dialysis. The physicochemical properties of CY-1 were characterized by UV, IR, SEM, NMR, and HPLC analyses. Structural characterizations revealed that CY-1 is a homogeneous heteropolysaccharide with an average molecular weight of 3.06 × 104 Da. CY-1 exhibited a honeycomb structure with an irregular branching shape, and it was composed of mannose, glucose, fucose, xylose, arabinose, galactose, rhamnose, and glucuronic acid, with molar fractions of 54.83%, 25.11%, 10.28% 4.53%, 2.12%, 1.64%, 0.83%, and 0.64%, respectively. In vitro hypoglycemic tests showed that CY-1 had an inhibitory effect on α-glucosidase. In addition, CY-1 of 160 µg/mL promoted glucose consumption in normal HepG2 cells. These results suggested that CY-1 may be a potential hypoglycemic agent.

Dissociable effects of transcranial direct current stimulation (tDCS) on early and later stages of visual motion perceptual learning.

Transcranial direct current stimulation (tDCS) has the potential to benefit visual perceptual learning (VPL). However, previous studies investigated the effect of tDCS on VPL within early sessions, and the influence of tDCS on learning effects at later stages (plateau level) is unclear. Here, participants completed 9 days of training on coherent motion direction identification to reach a plateau (stage 1) and then continued training for 3 days (stage 2). The coherent thresholds were measured before training, after stage 1 and after stage 2. In the first group, anodal tDCS was applied when participants trained over a period of 12 days (stage 1 + stage 2). In the second group, participants completed a 9-day training period without any stimulation to reach a plateau (stage 1); after that, participants completed a 3-day training period while anodal tDCS was administered (stage 2). The third group was treated the same as the second group except that anodal tDCS was replaced by sham tDCS. The results showed that anodal tDCS did not improve posttest performance after the plateau was reached. The comparison of learning curves between the first and third groups showed that anodal tDCS decreased the threshold at the early stage, but it did not improve the plateau level. For the second and third groups, anodal tDCS did not further enhance the plateau level after a continued 3-day training period. These results suggest that anodal tDCS boosts VLP during the early period of training sessions, but it fails to facilitate later learning effects. This study contributed to a deep understanding of the dissociable tDCS effects at distinct temporal stages, which may be due to the dynamic change in brain regions during the time course of VPL.

Flexor Tendon Repair Techniques: M-Tang Repair.

The authors present the methods and outcomes from six institutes where M-Tang repairs with early active flexion exercise are used for zone 2 digital flexor tendon repair. The authors had close to zero repair ruptures, and few digits needed tenolysis. The excellent to good results are generally between 80% and 90%. In the pandemic period, less stringent therapy supervision might have allowed some patients to move too aggressively, with repair ruptures not seen before the pandemic in one institute. In Nantong, Yixing, and Saint John, the rupture incidence is zero to 1%. In Florence and Heidelberg, the rupture incidence was 3%.

Objective:To introduce a reliable and easy method of philtrum crest and philtrum repairing in secondary repair of cleft lip.Methods:Lift the upper lip flap after removing the scar on upper lip. Then the superficial orbicularis oris muscle was carefully separated, which formed the abnormal muscular eminence in the affected side after the first cleft lip repair. The pedicle of the orbicularis oris muscle the reconstructing philtrum crest. The lingual orbicularis oris muscle flap was lifted and curled from outside. The superficialorbicularis oris muscle was cut in philtrum longitudinally and turned outward. The two evertedorbicularisoris muscle flaps were sutured on both sides and fixed them on the reconstructing philtrum crest. The exposed deep orbicularis oris muscle in philtrum was sutured with the upper dermis, which formed the prominentphiltrum crest and deeper philtrum.Results:We reviewed the hospital records of patients from July 2008 to November 2021. In total, 201 patients were included in this study. All of these patients underwent the reconstruction of philtrum crest and philtrum with orbicularis oris muscle intertangling and philtrum plasty in secondary cleft lip repairing. During the treatment, the patients had no complications such as infection, hematoma and flap necrosis.198 patients were observed from 1 months to 36 months (7.8 months on average). All of them improved in different degrees in early postoperative period. Most reconstructed philtrum crest was raised and basically symmetrical with the contralateral side in shape. The philtrum was clear and the scar was not obvious. The reconstructed philtrum crest would decrease with time. 91.7% (90/98) patients were satisfied with the postoperative effects after three months.Conclusions:The method of reconstruction of philtrum crest and philtrum with orbicularis oris muscle intertangling and philtrum plasty in secondary cleft lip repairing is safe and effective. The long term postoperative effect is stable with high satisfaction as well. As a result, this method can be used as the philtrum crest and philtrum correction scheme for secondary cleft lip repairing.

Research progress of sarcopenic obesity and chronic liver disease / 中华肝脏病杂志

Sarcopenia has attracted increasing attention with the study of nutrition in patients with liver disease. Sarcopenia is an independent risk factor for a poor prognosis of liver disease and is becoming increasingly common in patients with liver disease. Studies have shown that patients with liver disease and sarcopenic obesity have a worse prognosis than patients with liver disease and simple sarcopenia or obesity. In clinical practice, it is easy to recognize patients with malnutrition and decreased muscle mass, but we often ignore those patients with normal body weight or even obesity who will likewise experience muscle mass loss. Simply relying on the monitoring of body mass and body mass index to assess the nutritional and muscle status of patients with liver disease is not accurate. At present, our understanding of the relationship between chronic liver disease and sarcopenic obesity is still poorly understood. In this paper, the research progress on chronic liver disease, sarcopenia, and sarcopenic obesity in recent years is reviewed so as to provide a theoretical basis for improving the clinical prognosis of patients with liver disease.

Predictors of delayed function independence in patients with acute vertebrobasilar artery occlusion achieved successful recanalization after endovascular therapy / 国际脑血管病杂志

Objective:To investigate the prevalence and predictors of delayed function independence (DFI) in patients with acute vertebrobasilar artery occlusion (VBAO) achieved successful recanalization after endovascular therapy.Methods:Patients with acute VBAO received endovascular treatment in the Departments of Neurology, the First Affiliated Hospital of University of Science and Technology and General Hospital of Eastern Theater Command, PLA from December 2015 to December 2018 were retrospectively enrolled. The demographic, clinical, laboratory and imaging data were collected. Early functional independence (EFI) was defined as the modified Rankin Scale score 0-2 at discharge, and DFI was defined as the modified Rankin Scale score 0-2 at 90 d after discharge for non-EFI patients. Multivariate logistic regression analysis was used to determine the independent predictors of DFI. Results:A total of 122 patients with acute VBAO were included. Their age was 61.8±11.9 years old and 91 (74.6%) were male. The median Glasgow Coma Scale (GCS) score was 7, the median National Institutes of Health Stroke Scale (NIHSS) score was 26.5, and the median posterior circulation Alberta Stroke Program Early CT Score (pc-ASPECTS) score was 9. Twenty-four patients (20.0%) had EFI; of the 98 patients with non-EFI, 18 (18.4%) had DFI. Multivariate logistic regression analysis showed that male (odds ratio [ OR] 0.038, 95% confidence interval [ CI] 0.002-0.658; P=0.025), cardiogenic embolism ( OR 0.116, 95% CI 0.023-0.579; P=0.009), baseline NIHSS score ( OR 1.136, 95% CI 1.040-1.242; P=0.005) and lung infection ( OR 6.089, 95% CI 1.451-25.562; P=0.014) were the independent predictors of DFI. Conclusions:Nearly 1/5 of the non-EFI patients have DFI. Male, cardiogenic embolism, lower baseline NIHSS score and without pulmonary infection are the independent predictors of DFI.

Effect of community management based on Roy′s adaptation model in patients with chronic obstructive pulmonary disease / 中华健康管理学杂志

Objective:To determine the effect of community management based on the Roy′s adaptation model (RAM) in patients with chronic obstructive pulmonary disease (COPD).Methods:This study was a cluster randomized controlled study, with the community as the cluster unit, and selected 805 COPD patients from 8 communities in Xuzhou City who had completed community registration before June 2019. A total of 735 patients actually completed follow-up and participated in intervention evaluation. They were randomly divided into control group (362 cases) and intervention group (373 cases) by random number table method. The control group received routine follow-up, while the intervention group received RAM intervention for 6 months. The forced expiratory volume in 1 second (FEV1)/forced volume vital capacity (FVC) ratio (FEV 1/FVC) and the modified British medical research council (mMRC) were used to assess the pulmonary function. The hospital anxiety and depression scales (HADS) were used to evaluate the mental health. The Chinese version of the Short Form Coping and Adaption Processing Scale (CAP-15) was used to assess the adaptive capacity. And the St. George′s Respiratory Questionnaire (SGRQ) was used to evaluate the quality of life in COPD patients. The t test or χ 2 test was used for pre-intervention comparisons between groups, and the repetitive measure analysis of variance (ANOVA) was used for post-intervention comparisons between groups. Results:After 6 months intervention, there were no significant differences in FEV 1/FVC radio between the two groups [(0.61±0.11) vs (0.62±0.12)] ( P=0.172). The scores of mMRC [(2.04±0.33) vs (2.77±0.31) points], HAD-A [(5.28±4.28) vs (6.99±4.41) points], HAD-D [(5.82±5.12) vs (7.27±4.93) points] and SGRQ [(40.17±9.30) vs (53.69±9.77) points] were all lower in the intervention group than those in the control group (all P<0.001). The CAPS-15 score was higher in the intervention group than that in the control group [(35.87±3.62) vs (26.1±3.47)] ( P<0.001). Conclusion:RAM could be used in community management of COPD patients, which could improve their dyspnea symptoms and psychological and physiological functions, also improve their adaptability and quality of life.

Objective:To explore the effect of group cognitive behavior therapy (GCBT) on anxiety, depression and quality of life in patients with chronic obstructive pulmonary disease (COPD) in community.Methods:From August to November 2019, patients with moderate COPD in 18 communities in Xuzhou City were randomly divided into the intervention group ( n=240) and the control group ( n=223). The control group received routine management and the intervention group received group cognitive behavioral therapy intervention for 8 weeks on the basis of routine management.Before and after the intervention, FEV 1% predicted value and FEV 1/FVC were measured by pulmonary function tester.Hospital Anxiety and Depression Scale (HADS) was used to evaluate the anxiety and depression of patients.St.George's respiratory questionnaire (SGRQ), COPD assessment test (CAT) and modified medical research council dyspnea (mMRC) were used to evaluate the quality of life of patients.SPSS 20.0 software was used for analysis.The χ 2 test, independent sample t-test, paired sample t-test were used for statistical analysis. Results:After 8 weeks of intervention, the anxiety and depression scores of the intervention group were lower than those of the control group (anxiety: (8.23±4.02) vs (10.71±3.60); depression: (7.87±3.73) vs (10.20±3.72)( t=6.415, 6.185, both P<0.01). After the intervention, there was no significant difference in FEV 1%((51.7±12.3)% vs (52.0±12.6)%) predicted value and FEV 1/FVC((57.3±10.8)% vs (56.9±10.7)%) between the two groups( t=-0.259, 0.400, both P>0.05). The scores of CAT, mMRC and SGRQ in the intervention group were lower than those in the control group((17.35±5.78) vs (20.90±8.00), (1.55±0.82) vs (2.30±1.21), (41.78±21.56) vs (57.08±24.46))( t=-5.061, -7.227, -6.580, all P<0.01). Conclusion:Group cognitive behavioral therapy can relieve the anxiety and depression and improve the quality of life of patients with COPD.

Practice of clinical pharmacists participating in fine management of pharmaceutical affairs in gastroenterology department based on DRG data / 中国药房

OBJECTIVE To explor e the effect of clinical pharmacists participatin g in fine management of pharmaceutical affairs among the inpatients in the department of gastroenterology based on diagnosis related groups （DRG）data. METHODS The discharged patients in the gastroenterology department of our hospital were selected as the research objects to compare the changes of DRG indicators and hospitalization related indicators before （from April to December 2019）and after （from April to December 2020 and from April to December 2021） pharmacists participating in fine management of pharmaceutical affairs in the gastroenterology department. The key DRG with the highest number of enrolled cases and DRG cases of the total cost overrun were analyzed to explore the deviation of various costs. The rationality of drug use was evaluated for the cases in each DRG that exceeded the benchmark hospital payment standard by three times ，with the help of prescription doctor ’s advice review. RESULTS In the first year of intervention ，the case combination index value of gastroenterology department was increased ，meanwhile，the cost consumption index ，time consumption index and average hospital stay were decreased significantly （P＜0.01）. In the second year of intervention ，total weight of the cases in gastroenterology department was increased ，while cost consumption index ，time consumption index ，hospitalization cost per time ，drug cost per time and average hospital stay were all decreased significantly ， compared with before intervention （P＜0.01）. Among the top five DRG ，the drug cost per time in the GZ 15，GZ13 and GJ 15 were all decreased significantly in the first year of intervention ；hospitalization cost per time and drug cost per time in the GZ 15，GZ13， GJ15 and GJ 13 were all decreased significantly in the second year of intervention （P＜0.01）；after the intervention of clinical pharmacists in DRG over-expenditure cases ，the over-expenditure rate decreased significantly （P＜0.001）. CONCLUSIONS The fine management of pharmaceutical affairs in our hospital has achieved certain results and promotes the rationality of clinical drug use，and provides a new entry point for the cost control and utilization of medical institutions under the background of 〔2020〕68号） DRG.

Flexor tendon repair: recent changes and current methods.

The current clinical methods of flexor tendon repair are remarkably different from those used 20 years ago. This article starts with a review of the current methods, followed by presentation of past experience and current status of six eminent hand surgery units from four continents/regions. Many units are using, or are moving toward using, the recent strong (multi-strand) core suture method together with a simpler peripheral suture. Venting of the critical pulleys over less than 2 cm length is safe and favours functional recovery. These repair and recent motion protocols lead to remarkably more reliable repairs, with over 80% good or excellent outcomes achieved rather consistently after Zone 2 repair along with infrequent need of tenolysis. Despite slight variations in repair methods, they all consider general principles and should be followed. Outcomes of Zone 2 repairs are not dissimilar to those in other zones with very low to zero incidence of rupture.
