Objective: To explore the effects of different types of acute exercise on the working memory of sedentary college students，so as to provide a basis for exercise intervention. Methods: From April 15 to May 30, 2023, a total of 42 sedentary college students were recruited from one university in Beijing. Using a single blind, completely randomized experimental design, participants were randomly assigned to an open skill exercise group, a closed skill exercise group, or a control group, with 14 participants in each group. The open skill exercise group engaged in 30 minutes of badminton, the closed skill exercise group performed 30 minutes of running, and the control group remained seated for 30 minutes. All participants completed a 2-back working memory task and had their electroencephalogram (EEG) data recorded before and after the intervention. Results: The accuracy rates of the open skill exercise group, closed skill exercise group, and control group (0.90±0.06, 0.94±0.05; 0.88±0.05, 0.94±0.05; 0.85±0.10, 0.90±0.06) showed a significant main effect of time ( F=37.14, P <0.01). Reaction times [(923.65±145.08, 711.56± 140.93 ; 909.59±180.28, 807.85±169.66; 917.05±166.35, 871.86±186.07)ms] showed both a significant main effect of time and a significant interaction between group and time ( F=70.55, 11.83, P <0.01). Repeated measures ANOVA revealed that all three groups improved in accuracy and reaction time compared to pre test values, with no significant difference in accuracy between groups. However, the reaction time of the open skill exercise group was significantly faster than that of the control group ( P <0.05), while there was no significant difference between the closed skill exercise group and the control group ( P >0.05). For EEG data, the P2 amplitude showed a significant main effect of time and a significant interaction between groups and time ( F=10.60, 7.66, P < 0.01 ), with the open skill exercise group exhibiting a higher P2 amplitude than the control group ( P <0.05), while the closed skill exercise group showed no significant difference compared to the control group ( P >0.05). The N2 amplitude showed a significant main effect of time ( F=5.94, P <0.05). The P3 amplitude showed significant main effects of time and electrode position, as well as a significant interaction between groups and time ( F=23.16, 4.53, 5.85, P <0.05), with both exercise groups exhibiting higher P3 amplitudes than the control group ( P <0.05), but no significant difference between the two exercise groups ( P >0.05). Conclusion Open skill exercise is more effective than closed skill exercise in improving the working memory of sedentary college students.

Current research hotspots and future development trends mainly included the following aspects: TCM compounds, acupuncture therapy, oxidative stress, nerve conduction velocity, expression of related pathogenic genes, randomized controlled experiments, data mining, systematic evaluation, etc.Conclusion:At present, the research on the TCM prevention and treatment of diabetic peripheral neuropathy at home and abroad has gradually entered a stable development stage and has a certain research scale. However, it is necessary to strengthen the cooperation and communication between research teams and institutions and promote sustainable clinical efficacy evaluation and basic research development.

Sepsis-induced liver injury (SILI) is an important cause of septicemia deaths. BaWeiBaiDuSan (BWBDS) was extracted from a formula of Panax ginseng C. A. Meyer, Lilium brownie F. E. Brown ex Miellez var. viridulum Baker, Polygonatum sibiricum Delar. ex Redoute, Lonicera japonica Thunb., Hippophae rhamnoides Linn., Amygdalus Communis Vas, Platycodon grandiflorus (Jacq.) A. DC., and Cortex Phelloderdri. Herein, we investigated whether the BWBDS treatment could reverse SILI by the mechanism of modulating gut microbiota. BWBDS protected mice against SILI, which was associated with promoting macrophage anti-inflammatory activity and enhancing intestinal integrity. BWBDS selectively promoted the growth of Lactobacillus johnsonii (L. johnsonii) in cecal ligation and puncture treated mice. Fecal microbiota transplantation treatment indicated that gut bacteria correlated with sepsis and was required for BWBDS anti-sepsis effects. Notably, L. johnsonii significantly reduced SILI by promoting macrophage anti-inflammatory activity, increasing interleukin-10⁺ M2 macrophage production and enhancing intestinal integrity. Furthermore, heat inactivation L. johnsonii (HI-L. johnsonii) treatment promoted macrophage anti-inflammatory activity and alleviated SILI. Our findings revealed BWBDS and gut microbiota L. johnsonii as novel prebiotic and probiotic that may be used to treat SILI. The potential underlying mechanism was at least in part, via L. johnsonii-dependent immune regulation and interleukin-10⁺ M2 macrophage production.

Objective:To study the risk factors of complications after bowel resection for acute mesenteric ischemic disease.Methods:Retrospective case-control study was used to analyze the case data of 68 patients diagnosed with acute mesenteric ischemic disease (AMI) with bowel resection at the First Medical Center of the PLA General Hospital from January 2010 to January 2020, including 43 males and 25 females. The patients were divided into complication group ( n=21) and the non-complication group ( n=47) according to whether they had complications after surgery. The risk factors associated with the development of postoperative complications were analyzed by multivariate Logistic stepwise regression method to determine the risk factors with clinical significance. Measurement data with normal distribution were expressed as mean ± standard deviation ( ± s), and t-test was used for comparison between groups. Chi-square test was used for comparison between count data groups. Results:Univariate analysis showed that age >60 years, Marshall score≥2, type of resected bowel, pathology suggestive of irreversible transmural necrosis, length of ICU stay >6 d, length of mechanical ventilation >2 d, American Society of Anesthesiologists (ASA) classification, and preoperative procalcitonin≥2 ng/mL were the risk factors affecting the development of complications after bowel resection for acute mesenteric ischemic disease risk factors ( P<0.05). Multivariate Logistic regression analysis showed that age>60 years ( HR=12.364, 95% CI: 1.135-134.662, P=0.039) and preoperative procalcitonin ≥2 ng/mL ( HR=14.144, 95% CI: 1.280-156.303, P=0.031) were independent risk factors for the development of postoperative complications after AMI parallel bowel resection. Conclusion:The rate of complications after combined bowel resection for AMI is high. When patients are combined with age>60 years and preoperative procalcitonin≥2 ng/mL, preoperative prevention of postoperative complications should be emphasized to improve the prognosis of patients.

Thyroid nodule is a common endocrine system disease in clinic. Its onset is mostly related to affect-mind internal damage. The core pathogenesis is dysfunction of the liver and liver-qi stagnation, and the main pathological changes are qi stagnation, phlegm turbidity and blood stasis. Constitution is inherited from the natural factors and nourished from the postnatal factors, which is closely related to the occurrence of diseases, the transformation of syndromes and the transmission of diseases. Chaihu constitution refers to the type of constitution suitable for long-term use of Bupleuri Radix and prescriptions about Bupleuri Radix. The characteristics of patients with Chaihu constitution are similar to those of patients with thyroid nodules in clinic, and the risk of developing thyroid nodules is higher. Chaihu constitution is the internal basis of thyroid nodules. When treating thyroid nodule patients with Chaihu constitution, the dominant position of Bupleuri Radix should be highlighted, and Bupleuri Radix and prescriptions about Bupleuri Radix should be used flexibly. The dosage of Bupleuri Radix is mostly between 6-15 g, and according to the change of pathogenesis, it is often combined with Chinese materia medica with the efficacy of soothing liver and promoting qi, resolving phlegm and removing turbidity, promoting blood circulation and removing blood stasis, in order to prevent the occurrence and development of thyroid nodules.

ObjectiveTo explore the mechanism of Renshen Baidusan in repairing intestinal mucosa in ulcerative colitis （UC） by regulating autophagy to scavenge peroxides. MethodThe mouse model of UC was induced by free drinking of 3.0% dextran sulphate sodium （DSS） solution. Sixty male C57BL/6J mice were randomized into normal， model， mesalazine （0.3 g·kg^-1）， and high-， medium-， and low-dose （12.35， 8.22， 4.11 g·kg^-1， respectively） Renshen Baidusan groups （n=10）. The mice were administrated with corresponding drugs by gavage for 7 consecutive days. The colon tissue was stained with hematoxylin-eosin （HE） to reveal the pathological changes， and Alcian blue-Periodic acid Scheff （PAS/AB） staining was employed to observe the goblet cell changes. The fluorescence expression of reactive oxygen species （ROS） in the colon tissue was detected by the immunofluorescence assay. The activity of superoxide dismutase （SOD） and the content of malondialdehyde （MDA） were measured by the biochemical methods. Western blot was employed to determine the expression levels of proliferating cell nuclear antigen （PCNA）， microtubule-associated protein 1 light chain 3 （LC3）， leucine-rich repeat-containing G protein-coupled receptor 5 （LGR5）， and p62. ResultDestroyed mucosal epithelial structure， intestinal gland destruction， loss of goblet cells， and massive infiltration of inflammatory cells appeared in the model group. Compared with the normal group， the model group showed increased tissue damage injury （TDI） score of the colon tissue， decreased SOD activity and LC3Ⅱ/Ⅰ， PCNA value， and elevated levels of p62， MDA， ROS， and LGR5 （P<0.05）. Compared with the model group， different doses of Renshen Baidusan decreased the TDI score， promoted the generation of new goblet cells， elevated the levels of PCNA， LGR5， SOD， and LC3Ⅱ/Ⅰ， and lowered the levels of p62， MDA， and ROS （P<0.05）. Moreover， the low dose group showed the best performance （P<0.05）. ConclusionRenshen Baidusan can promote intestinal epithelial repair by activating intestinal autophagy， alleviating oxidative stress， and promoting intestinal stem cell proliferation and differentiation.

ObjectiveTo explore the mechanisms of internal treatment （Renshen Baidusan）， external treatment （Yurui Enema）， and combination of the two methods in treating intestinal mucosal injury in the rat model of ulcerative colitis （UC） from the changes of phosphatidylinositol-3 kinase （PI3K）/protein kinase B （Akt）/nuclear factor-κB （NF-κB） pathway. MethodFifty SPF-grade SD rats were randomized into blank， model， Renshen Baidusan （15.6 g·kg^-1）， Yurui Enema （25 g·kg^-1）， and combined treatment （15.6 g·kg^-1 Renshen Baidusan + 25 g·kg^-1 Yurui Enema） groups （n=10）. The rat model of UC was established in other groups except the blank group by 2，4， 6-trinitrosulfonic acid （TNBS）/ethanol. The rats were administered with corresponding drugs once a day for 14 consecutive days since the 8th day after modeling. The histopathological changes of colon were observed by hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of tumor necrosis factor （TNF）-α， interferon （IFN）-γ， interleukin （IL）-4， and IL-10 in the colon tissue. The apoptosis of colon epithelial cells was detected by terminal deoxynucleotidyl transferase-mediated nick end labeling （TUNEL）. The location and expression of B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， TNF-α， and IL-6 in the colon tissue were examined by immunohistochemistry. Real-time quantitative fluorescence polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the mRNA and protein levels， respectively， of the proteins in the PI3K/Akt/NF-κB pathway in the colon tissue. ResultIn the model group， HE staining showed a large number of inflammatory cell infiltration in the mucosa and submucosa. Compared with the blank group， the model group showed elevated levels of TNF-α and IFN-γ and lowered levels of IL-4 and IL-10 in the colon tissue， increased apoptosis rate of colon epithelial cells， increased positive expression of Bax， TNF-α， and IL-6， and decreased positive expression of Bcl-2 （P<0.05）. Moreover， the model group showed up-regulated mRNA levels of PI3K， Akt， and NF-κB and protein levels of PI3K， p-PI3K， Akt， p-Akt， p65， p-p65， Bax， and cleaved Caspase-3， increased Bax/Bcl-2 and cleaved Caspase-3/Caspase-3 ratios， and down-regulated protein levels of NF-κB suppressor protein α（IκBα）， Bcl-2， and Caspase-3 in the colon tissue （P<0.05）. Compared with the model group， the internal treatment， the external treatment， and the combination （referred to as the three groups） alleviated the colonic mucosal injury， lowered the levels of TNF-α and IFN-γ and elevated the levels of IL-4 and IL-10 in the colon tissue， decreased the apoptosis rate of colon cells， inhibited the positive expression of Bax， TNF-α， and IL-6， and promoted the positive expression of Bcl-2 （P<0.05）. Furthermore， the combination group down-regulated the mRNA level of PI3K （P<0.05）. The three groups down-regulated the mRNA levels of Akt and NF-κB and the protein levels of p-PI3K， Akt， p-Akt， p65， p-p65， Bax， and cleaved Caspase-3 in the colon tissue， decreased the Bax/Bcl-2 and cleaved Caspase-3/Caspase-3 ratios， and up-regulated the protein levels of IκBα， Bcl-2， and Caspase-3 （P<0.05）. ConclusionRenshen Baidusan， Yurui Enema， and their combination may inhibit the activation of PI3K/Akt/NF-κB signaling pathway and regulate the expression of genes and proteins related to this pathway to achieve anti-inflammatory and anti-apoptotic effects， thus restoring the intestinal mucosal barrier function of UC rats.
