“Runner’s high” refers to a momentary sense of pleasure that suddenly appears during running or other exercise activities, characterized by anti-anxiety, pain relief, and other symptoms. The neurobiological mechanism of “runner’s high” is unclear. This review summarizes human and animal models for studying “runner’s high”, analyzes the neurotransmitters and neural circuits involved in runner’s high, and elucidates the evidence and shortcomings of researches related to “runner’s high”. This review also provides prospects for future research. Research has found that exercise lasting more than 30 min and with an intensity exceeding 70% of the maximum heart rate can reach a “runner’s high”. Human experiments on “runner’s high” mostly use treadmill exercise intervention, and evaluate it through questionnaire surveys, measurement of plasma AEA, miRNA and other indicators. Animal experiments often use voluntary wheel running intervention, and evaluate it through behavioral experiments such as conditional place preference, light dark box experiments (anxiety), hot plate experiments (pain sensitivity), and measurement of plasma AEA and other indicators. Dopamine, endogenous opioid peptides, endogenous cannabinoids, brain-derived neurotrophic factor, and other substances increase after exercise, which may be related to the “runner’s high”. However, attention should be paid to the functional differences of these substances in the central and peripheral regions, as well as in different brain regions. Moreover, current studies have not identified the targets of the neurotransmitters or neural factors mentioned above, and further in-depth researches are needed. The mesolimbic dopamine system, prefrontal cortex-nucleus accumbens projection, ventral hippocampus-nucleus accumbens projection, red nucleus-ventral tegmental area projection, cerebellar-ventral tegmental area projection, and brain-gut axis may be involved in the regulation of runner’s high, but there is a lack of direct evidence to prove their involvement. There are still many issues that need to be addressed in the research on the neurobiological mechanisms of “runner’s high”. (1) Most studies on “runner’s high” involve one-time exercise, and the characteristics of changes in “runner’s high” during long-term exercise still need to be explored. (2) The using of scales to evaluate subjects lead to the lacking of objective indicators. However, some potential biomarkers (such as endocannabinoids) have inconsistent characteristics of changes after one-time and long-term exercise. (3) The neurotransmitters involved in the formation of the “runner’s high” all increase in the peripheral and/or central nervous system after exercise. Attention should be paid to whether peripheral substances can enter the blood-brain barrier and the binding effects of neurotransmitters to different receptors are completely different in different brain regions. (4) Most of the current evidence show that some brain regions are activated after exercise. Is there a functional circuit mediating “runner’s high” between these brain regions? (5) Although training at a specific exercise intensity can lead to “runner’s high”, most runners have not experienced “runner’s high”. Can more scientific training methods or technological means be used to make it easier for people to experience the “runner’s high” and thus be more willing to engage in exercise? (6) The “runner’s high” and “addiction” behaviors are extremely similar, and there are evidences that exercise can reverse addictive behaviors. However, why is there still a considerable number of people in the sports population and even athletes who smoke or use addictive drugs instead of pursuing the “pleasure” brought by exercise? Solving the problems above is of great significance for enhancing the desire of exercise, improving the clinical application of neurological and psychiatric diseases through exercise, and enhancing the overall physical fitness of the population.

Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.

ObjectiveTo analyze the distribution, drug resistance characteristics, and changing trends of Acinetobacter baumannii (AB) isolated from environmental surfaces and healthcare workers’ hands in a grade Ⅱ level A general hospital in Xuhui District of Shanghai from 2018 to 2023, and to provide reference for infection control in the hospital. MethodsEnvironmental samples were collected quarterly from critical surfaces and healthcare workers’ hands in the intensive care unit (ICU), geriatrics, and respiratory departments from 2018 to 2023. Clinical isolates were obtained from all patients with AB infections in ICU, geriatrics, respiratory department, rehabilitation department, infectious diseases department, emergency department, cardiology department, and orthopedics of the hospital from 2018 to 2023. Retrospective analyses were performed on AB detection rates, strain origins, resistance rates to commonly used antimicrobial agents, and resistance gene features, comparing the antimicrobial resistance between clinically isolated strains and environmentally isolated strains. ResultsFrom 2018 to 2023, a total of 1 416 samples were collected from the hospital and a total of 272 strains of AB were detected, with a positive detection rate of 19.21%. The detection rate gradually decreased year-on-year (χ²_trend=45.290, P<0.001). The majority of samples originated from patient-contacted items (34.56%, 94/272), followed by shared items (26.84%, 73/272) and healthcare worker-contacted items (15.07%, 41/272). From 2018 to 2023, the resistance rate of AB on environmental surfaces and healthcare workers’ hands to commonly tested antibiotics in the hospital ranged from 10% to 40%. The resistance rates to cefotaxime (42.52%) and piperacillin (38.58%) were relative high, while the resistance to polymyxin E (1.57%), polymyxin B (2.36%), and doxycycline (3.94%) maintained low. The annual fluctuations in resistance to cefotaxime, piperacillin, ceftriaxone, tobramycin, doxycycline, minocycline and cotrimoxazole were statistically significant (all P<0.05). There were statistically significant differences in the resistance of clinical and environmental isolates to ampicillin/sulbactam, cefepime, ceftazidime, subamphetamine, meropenem, piperacillin, aztreonam, gentamicin, tobramycin, minocycline, ciprofloxacin, levofloxacin, and cotrimoxazole in the hospital from 2018 to 2023 (all P<0.05). The resistance rate of clinical isolates was generally high, especially to β-lactam and quinolone drugs, which were mostly above 80% [such as cefepime (93.86%), cefotaxime (97.37%), imipenem (98.25%), and ciprofloxacin (99.12%)]. The resistance rate of environmental isolated strains to similar antibiotics was relatively lower, mostly concentrated at 10%‒30%. The whole-genome sequencing of 34 carbapenem-resistant Acinetobacter baumannii (CRAB) strains isolated from the hospital environment in 2023 revealed that the main resistance mechanism was overexpression of efflux pumps (51.97%), followed by changes in target sites (32.46%). Among the 34 CRAB strains, carbapenem resistance genes OXA-23 and OXA-51 were detected in 6 strains (17.65%), while genes such as KPC, IMP, VIM, and SIM were not detected. ConclusionFrom 2018 to 2023, AB in the hospital environment exhibited high resistance rates to certain antimicrobial agents and carried multiple resistance genes, indicating a potential transmission risk. It is necessary to further strengthen bacterial resistance monitoring and hospital infection control, and use antibiotics reasonably.

Osteoporosis is a prevalent skeletal condition characterized by reduced bone mass and strength, leading to increased fragility. Buqi-Tongluo (BQTL) decoction, a traditional Chinese medicine (TCM) prescription, has yet to be fully evaluated for its potential in treating bone diseases such as osteoporosis. To investigate the mechanism by which BQTL decoction inhibits osteoclast differentiation in vitro and validate these findings through in vivo experiments. We employed MTS assays to assess the potential proliferative or toxic effects of BQTL on bone marrow macrophages (BMMs) at various concentrations. TRAcP experiments were conducted to examine BQTL's impact on osteoclast differentiation. RT-PCR and Western blot analyses were utilized to evaluate the relative expression levels of osteoclast-specific genes and proteins under BQTL stimulation. Finally, in vivo experiments were performed using an osteoporosis model to further validate the in vitro findings. This study revealed that BQTL suppressed receptor activator of NF-κB ligand (RANKL)-induced osteoclastogenesis and osteoclast resorption activity in vitro in a dose-dependent manner without observable cytotoxicity. The inhibitory effects of BQTL on osteoclast formation and function were attributed to the downregulation of NFATc1 and c-fos activity, primarily through attenuation of the MAPK, NF-κB, and Calcineurin signaling pathways. BQTL's inhibitory capacity was further examined in vivo using an ovariectomized (OVX) rat model, demonstrating a strong protective effect against bone loss. BQTL may serve as an effective therapeutic TCM for the treatment of postmenopausal osteoporosis and the alleviation of bone loss induced by estrogen deficiency and related conditions.

OBJECTIVE: To explore the clinical significance of circulating tumor DNA (ctDNA) in response evaluation and relapse monitoring for patients with primary mediastinal large B-cell lymphoma (PMBCL). METHODS: The clinical characteristics, efficacy and survival of 38 PMBCL patients in our hospital from January 2010 to April 2020 were retrospectively analyzed. The ctDNA monitoring was conducted by targeted next-generation sequencing (NGS). RESULTS: Among the 38 patients, 26 cases were female, and 32 cases were diagnosed with Ann Arbor stage I-II. The 5-year overall survival (OS) rate and progression-free survival (PFS) rate were 74.7% and 61.7%, respectively. Males and those with high aaIPI scores (3 points) had a relatively poor prognosis. The NGS results of 23 patients showed that STAT6 (65.2%), SOCS1 (56.5%), and TNFAIP3 (56.5%) were the most common mutated genes. Patients with stable disease (SD)/progressive disease (PD) exhibited enrichment in cell cycle, FoxO, and TNF signaling pathways. A total of 29 patients underwent end-of-treatment PET/CT (EOT PET/CT), and 16 of them received ctDNA monitoring with 12 negative. Among 6 patients with EOT PET/CT positive (Deauville 4), 4 underwent ctDNA monitoring, and 3 of them were negative, being still in continuous remission without any subsequent anti-tumor therapy. CONCLUSION CtDNA may be combined with PET/CT to assess efficacy, monitor relapse, and guide treatment of PMBCL.

BACKGROUND:Related studies have shown that bone density,postoperative infection,adjacent vertebral fracture,and lumbar fascial edema may be risk factors for lingering pain after vertebroplasty.OBJECTIVE:To scrutinize the risk factors for lumbar fascia edema in osteoporotic vertebral compression fractures patients and investigate its influence on lingering pain after vertebroplasty.METHODS:A retrospective analysis was conducted on 204 osteoporotic vertebral compression fractures patients who underwent percutaneous vertebroplasty at the Clinical Medical College of Yangzhou University from February to October 2022.Patients were categorized based on MRI findings into two groups:without lumbar fascia edema(84 cases)and with lumbar fascia edema(120 cases).Preoperative data,encompassing age,gender,height,weight,body mass index,bone density,serum total protein,serum albumin,inflammatory markers(C-reactive protein and erythrocyte sedimentation rate),degree of fracture compression,presence of prior compression fractures,fracture count,lumbar instability,and Japanese senile independence score were gathered.Postoperative follow-up recorded data such as the number of new vertebral fractures and visual analog scale scores were recorded.Logistic regression method was used to analyze the risk factors of lumbar fascial edema,and the receiver operating characteristic curve was used to determine whether the risk factors had relevant diagnostic significance.RESULTS AND CONCLUSION:(1)Age,prior vertebral compression fractures,Japanese senile independence score score,and lumbar instability presence emerged as autonomous risk factors for lumbar fascia edema in osteoporotic vertebral compression fractures patients,with corresponding odds ratios of 2.76,1.70,2.56,and 4.74,respectively.(2)Employing a visual analog scale score of 4 at 1 month postoperatively to distinguish residual pain revealed 31 cases with residual pain in the lumbar fascia edema group,in contrast to only 8 cases in the non-fascia edema group(P＜0.01).(3)The fascia edema group exhibited a significantly higher visual analog scale score at 1 month postoperatively(2.12±1.35)compared to the group without fascia edema(1.67±1.08)(P＜0.01).(4)It is indicated that age,Japanese senile independence score,prior compression fractures,and lumbar instability presence independently contribute to lumbar fascia edema in osteoporotic vertebral compression fractures patients.Lumbar fascia edema emerges as a determinant of persistent pain in the lumbar region following percutaneous vertebroplasty in these patients.

Objective To investigate the association of endometrial thickness(EMT)with obstetric and neonatal outcomes of monoparous pregnancy in fresh cleavage embryos transfer.Methods A total of 1 845 patients of monoparous pregnancy after fresh cleavage embryos transfer cycles from Jan 2016 to Mar 2022 at Shanghai First Maternity and Infant Hospital,Tongji Universtiy were analyzed retrospectively.Patients were categorized into three groups by EMT on transferation day:≤8 mm(group A),8-14 mm(group B)and≥14 mm(group C).The primary outcomes were preterm birth(PTB),birth weight and birth weight z-score,small-for-gestation age,large-for-gestation age,very low birth weight,low birth weight and macrosomia.The second outcomes were pregnancy and perinatal complications.The relationship between EMT and adverse neonatal outcomes was estimated by Logistic regression analysis.Results The rate of ectopic pregnancy was increased significantly in group A.No significant differences were found among the three groups in gestation age,birth weight,birth weight z-score,PTB,small for gestation age,large for gestation age,low birth weight,very low birth weight and macrosomia.Compared with group B,the odds of adverse neonatal outcomes did not show significant differences before and after adjustment in both group A and group C by Logistic regression analysis.Conclusion Thinner EMT in fresh cleavage embryos transfer is associated with higher rate of ectopic pregnancy,while it is not independently associated with adverse perinatal outcomes.

Objective:To evaluate the predictive value of whole blood cell derived inflammatory marker (including systemic immunoinflammatory index (SII), systemic inflammatory response index (SIRI), neutrophil count/lymphocyte count (NLR), platelet count/lymphocyte count (PLR), and monocyte count/lymphocyte count (MLR)) and in combination with N-terminal pro-B-type natriuretic peptide (NT-proBNP) on the prognosis of patients with chronic heart failure.Methods:This study was a retrospective cohort study. Patients with chronic heart failure hospitalized in the Department of Cardiovascular Medicine, Nanfang Hospital, Southern Medical University from January 2019 to August 2022 were enrolled. Patients were followed up and were divided into survival group and death group according to the follow-up results. Clinical characteristics of the two groups were compared. Receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value of each whole blood cell derived inflammatory marker for predicting all-cause death in patients with chronic heart failure. Kaplan-Meier survival curve was drawn, and log-rank test was used to compare the difference in survival of chronic heart failure patients with different levels of whole blood cell derived inflammatory markers. Univariate and multivariate Cox proportional hazards models were used to analyze the effects of whole blood cell derived inflammatory markers and NT-proBNP on the all-cause death of patients with chronic heart failure. ROC curve was used to analyze the predictive value of whole blood cell derived inflammatory markers combined with NT-proBNP on the prognosis of patients with chronic heart failure.Results:A total of 324 patients with heart failure aged (64.76±13.78) years were enrolled, with 212 males (65.43%). 297 patients (91.67%) completed follow-up, 27 patients (8.33%) were lost to follow-up. The follow-up time was 24.0 (18.0, 41.8) months. There were 258 patients in the survival group and 66 patients in the death group. The optimal cut-off values of SII, SIRI, NLR, PLR and MLR determined by ROC curve were 739.83, 1.65, 3.14, 151.95 and 0.37, respectively. Kaplan-Meier survival curve analysis showed that patients with chronic heart failure with high levels of SII (≥739.83), SIRI (≥1.65), NLR (≥3.14), PLR (≥151.95) and MLR (≥0.37) had higher incidence of all-cause death than patients with low levels of inflammatory markers (all P<0.001). Multivariate Cox proportional hazard regression analysis showed that age ( HR=1.04, 95% CI 1.01-1.06, P=0.002), NT-proBNP ( HR=2.93, 95% CI 1.64-5.23, P<0.001), SII≥739.83 ( HR=3.27, 95% CI 1.18-9.02, P=0.022) and PLR≥151.95 ( HR=2.67, 95% CI 1.02-6.96, P=0.045) were independent predictors of all-cause death in patients with chronic heart failure. ROC curve analysis showed that the predictive value of SII and PLR combined with NT-proBNP ( AUC=0.850) for the prognosis of patients with chronic heart failure was better than that of SII ( AUC=0.779)、PLR ( AUC=0.782)、NT-proBNP ( AUC=0.727) and CRP ( AUC=0.668) alone (all P<0.001). Conclusions:Whole blood cell derived inflammatory markers——SII, PLR, and NT-pro BNP were independently associated with all-cause death in patients with chronic heart failure. SII and PLR can independently predict the prognosis of patients with chronic heart failure, combination of SII and PLR with NT-pro BNP has better predictive value for the prognosis of patients with chronic heart failure.

The 30 best pieces of evidence were summarized from 6 aspects: preoperative evaluation and preparation, intraoperative prevention, diagnosis, diet and nutrition management, monitoring and treatment, and health education.Conclusions:This study summarized relevant evidence and provides reference for medical staff to formulate intervention measures and management plans for chyle leakage after thyroid cancer surgery.

Objective To explore the significance of the toxicity mechanism of butyl benzyl phthalate(BBP)in prevention and treatment of pulmonary fibrosis.Methods In this study,we used network toxicology combined with molecular docking technology to screen the targets of BBP and those related to pulmonary fibrosis through PubChem,GeneCards and other databases,and analyzed the intersecting genes by using a Wayne diagram.Protein-protein interaction networks were constructed to screen the core targets,and the pathway mechanisms were revealed by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes.Finally,molecular docking using AutoDock was performed to verify the binding patterns of core targets and BBP.Results A total of 91 potential targets of BBP-induced lung fibrosis were screened,among which PTGS2 and CYP3A4 were the core targets(binding energies of-1.84 kcal/mol and-1.68 kcal/mol,respectively).Enrichment analysis showed that BBP regulated the fibrosis process through G protein-coupled receptor signaling pathway,calcium signaling pathway and cyclic adenosine monophosphate signaling pathway.Molecular docking confirmed that BBP was stably bound to the core target through hydrogen bonding and hydrophobic interaction.Conclusion This study provides preliminary insights into the molecular mechanism of BBP-induced pulmonary fibrosis through network toxicology,and PTGS2 and CYP3A4 may play key roles in BBP-induced pulmonary fibrosis,which provides a novel reference for the exploration of the mechanism of toxicant-disease association.
