ObjectiveTo explore the possible mechanism of Tongbian Decoction （通便汤， TD） in treating slow transit constipation （STC）. MethodsTwenty-four SD rats were randomly divided into normal group， model group， TD group， and mosapride group， with 6 rats per group. Except for the normal group， STC models were established by intragastric administration of loperamide hydrochloride combined with normal saline. On the day following successful model establishment， rats in the TD group received 18.63 g·kg⁻¹ of TD by gavage， while those in the mosapride group received 1.605 mg·d⁻¹ of mosapride， and those in the normal group and the model group received 10 ml·kg⁻¹ of normal saline by gavage. All treatments were administered once daily for 7 consecutive days. Twenty-four hours after the last administration， fecal pellet number and fecal water content were measured. After intragastric administration of a 10% activated charcoal suspension， the small intestinal transit rate was calculated 30 minutes later. Serum levels of gastrin （GAS） and motilin （MTL） were measured by ELISA. Colonic histopathology was observed by HE staining， and mucus secretion by Alcian blue-periodic acid-Schiff （AB-PAS） staining. Ultrastructure of colon tissue was examined using transmission electron microscopy. Protein expression levels of C-kit， stem cell factor （SCF）， autophagy-related protein 5 （ATG5）， Beclin1， vesicle-associated membrane protein B （VAPB）， and protein tyrosine phosphatase interacting protein 51 （VAPB-PTPIP51） were measured by Western Blot， and the mRNA levels were detected by real-time PCR. Immunohistochemistry was used to detect SCF， C-kit， Beclin1， and ATG5 expression. The calcium content in colon tissue was determined by ELISA. ResultsCompared to the normal group， rats in the model group showed significantly reduced fecal pellet number， fecal water content， small intestinal transit rate， and serum GAS and MTL levels （P＜0.01）； the number of goblet cells decreased， and the mucosal and muscular layers of the colon became thinner； mRNA and protein expression levels of ATG5 and Beclin1 in colon tissue significantly increased， while calcium content decreased （P＜0.05 or P＜0.01）； and electron microscopy revealed vacuolar degeneration and increased autophagosomes in colonic cells. Compared to the model group， both TD group and mosapride group showed increased fecal pellet number， fecal water content， small intestinal transit rate， serum GAS and MTL levels， and colonic calcium content， along with decreased Beclin1 and ATG5 protein levels （P＜0.05 or P＜0.01）； the mucosal thickness and goblet cell number increased significantly， and autophagosomes decreased； in the TD group， ATG5 and Beclin1 mRNA levels decreased； in the mosapride group， SCF， VAPB， and PTPIP51 mRNA levels increased， while Beclin1 mRNA decreased （P＜0.05 or P＜0.01）. Compared to the mosapride group， the TD group showed higher fecal pellet number， fecal water content， serum GAS levels， colonic calcium content， and C-kit expression， along with lower ATG5 and Beclin1 levels （P＜0.05 or P＜0.01）. ConclusionTD may improve constipation symptoms by upregulating the VAPB-PTPIP51 complex during mitochondria-endoplasmic reticulum interactions， reducing autophagy of interstitial cells of Cajal， and promoting intestinal motility.

Follicular lymphoma(FL)is a type of non-Hodgkin's lymphoma,and its treatment options face many challenges.This paper discusses the pathogenesis and treatment of FL based on the clear-turbid theory in traditional Chinese medicine(TCM)."The clear and the turbid being related,and the rise and fall of qi being disorderly"is the basic pathogenesis of FL.As the disease progres-ses,"evil qi being blocked inside,and turbid evil harming the clear"aggravates,and finally"evil qi is strong and the disease progres-ses,and evil poison is generated inside".Based on this theory,the method of raising the clear and lowering the turbid and the method of dispersing the clear and removing the turbid are proposed to treat FL.The emphasis of raising the clear and lowering the turbid is to take raising and lowering as the key,movement and stillness as the pivot,and to treat the middle jiao;the emphasis of dispersing the clear and removing the turbid is to clear the triple jiao,warm the yang and invigorate the qi,and harmonize the spleen and kidney.Ca-ses are attached to illustrate,providing new ideas for the TCM treatment of FL.

Objective This study aimed to investigate the relationship between multiple inflammatory markers and poor outcome in patients with intracerebral hemorrhage,and to compare their predictive abilities.Methods We retrospectively analyzed the patients with intracerebral hemorrhage admitted to the Department of Neurology of the First Affiliated Hospital of Nanchang University from January 1,2015 to March 31,2023.According to the Modified Rankin Scale at 90 days after onset,the patients were divided into good outcome(mRS≤2 points)and poor outcome(mRS score≥3 points).Clinical information,laboratory examinations and follow-up data were compared between the two groups.Inflammatory markers include neutrophil to lymphocyte ratio(NLR),platelet to lymphocyte ratio(PLR),monocyte to high-density lipoprotein ratio(MHR),systemic inflammatory response index(SIRI),systemic immune-inflammation index(SII),white blood cell count to mean platelet volume ratio(WMR),lymphocyte to monocyte ratio(LMR),and systemic coagulation-inflammation index(SCI).Univariate and multivariate logistic regression analysis were used to analyze the predictors of poor prognosis after intracerebral hemorrhage,and receiver operating characteristic curve(ROC)was constructed to compare their predictive ability.Results A total of 510 patients with intracerebral hemorrhage were included.Of those,297(58.2%)had good outcome,and 213(41.8%)had poor outcome.Comparison of baseline characteristics demonstrated that patients with poor prognosis had higher levels of white blood cells,neutrophils,high-density lipoprotein,fibrinogen,NLR,PLR,SIRI,SII,WMR at admission,larger baseline hematoma volume and baseline perihematomal edema volume,a higher proportion of lobar hemorrhage,older age,and lower levels of platelets,lymphocytes,LMR,and SCI(P<0.05).Multivariate regression analysis showed that NLR(OR:1.081,95%CI:1.032～1.1131,P=0.001),SIRI(OR:1.089,95%CI:1.014～1.169,P=0.019),SII(OR:1.000,95%CI:1.000～1.001,P=0.011),WMR(OR:2.627,95%CI:1.267～5.445,P=0.009)were independently associated with poor prognosis in patients with ICH.In ROC analysis,the area under the curve of NLR(0.729,95%CI:0.685～0.774)was higher than SIRI(0.692,95%CI:0.645～0.738),SII(0.688,95%CI:0.641～0.735)and WMR(0.65,95%CI:0.602～0.698)for predicting poor outcomes.Conclusion NLR,SIRI,SII and WMR at admission are independently associated with poor outcomes in patients with intracerebral hemorrhage,and NLR has the strongest predictive ability.

BACKGROUND:Poly(lactic-co-glycolic acid)copolymer with good biosafety,biodegradability,and superior mechanical properties has become a focal point of research in stomatology.OBJECTIVE:To review the advance in stomatology of poly(lactic-co-glycolic acid)copolymer.METHODS:Using a computer-assisted search of relevant literature published in the China National Knowledge Infrastructure(CNKI)and PubMed databases,the search terms included"polylactic acid-hydroxyacetic acid,PLGA,oral defect,tissue engineering"in Chinese,and"PLGA,polylactic acid-hydroxyacetic acid copolymer,poly(lactic-co-glycolic acid)copolymer,dent*,regeneration,caries,periodontal,pulp,implant,alveolar bone"in English.Preliminary screening was conducted by reading titles and abstracts,excluding literature unrelated to the theme of the article.Based on the inclusion and exclusion criteria,a total of 119 articles were included for review.RESULTS AND CONCLUSION:In the field of stomatology,the application scope of poly(lactic-co-glycolic acid)copolymer is rapidly expanding,gradually replacing the traditional therapeutic drugs and restorative materials.Poly(lactic-co-glycolic acid)copolymer nanoparticles/microspheres can carry a variety of hydrophobic and hydrophilic active substances,demonstrating excellent delivery capabilities in caries prevention,root canal disinfection,and pulp capping treatment.In periodontal therapy,poly(lactic-co-glycolic acid)copolymer is widely used as a barrier membrane and drug carrier for periodontal tissue regeneration.Poly(lactic-co-glycolic acid)copolymer used for surface modification of implants not only enhances the antibacterial ability of the implant surface but also improves the bio-inert nature of the implant surface.The effect of pure poly(lactic-co-glycolic acid)copolymer scaffolds on treating bone defects is limited and requires the integration of 3D printing,various bioactive components,and inorganic materials to enhance scaffold performance.The combination of poly(lactic-co-glycolic acid)copolymer and stem cells can improve the effectiveness of nerve therapy,meeting clinical needs.Based on the great potential of poly(lactic-co-glycolic acid)copolymer in the field of stomatology,it is expected that in the future,repair materials with specific functions for different diseases will be produced according to different needs of oral tissue engineering.

The heart serves as the "energy factory" of the human body and is responsible for maintaining blood circulation and oxygen supplies.Its normal functioning thus relies on the generation of substantial amounts of ATP to support its mechanical activities.Under pathological conditions such as myocardial infarction,coronary artery sclerosis,and pulmonary hypertension,however,an insufficient blood supply leads to a reduced oxygen supply,subsequently activating a series of compensatory protective mechanisms.Hypoxia-inducible factor-1α(HIF-1α),as a nuclear transcription factor stably expressed under hypoxic conditions,has been shown to regulate oxygen transport by promoting angiogenesis and vasodilation,and to optimize oxygen utilization by regulating the balance of glucose and lipid metabolisms,thus participating in the regulation of various cardiac diseases.HIF-1α plays a crucial role in regulating cardiac energy metabolism and oxidative stress.This review systematically summarizes recent research regarding the various mechanisms of action of HIF-1α in reprogramming cardiac energy metabolism,explores its potential clinical applications in cardiovascular diseases,and proposes future research directions and possible treatment strategies.By comprehensively summarizing the mechanism of HIF-1α in ischemic heart disease,this article aims to provide new ideas and therapeutic targets for the prevention and treatment of cardiovascular diseases.

BACKGROUND:Some studies have shown a potential relationship between dietary intake and osteoarthritis,but whether there is a causal relationship between food preferences and osteoarthritis is still unknown.There is currently no large-scale genome-wide association study on dietary preferences and osteoarthritis in China.OBJECTIVE:To explore the causal association between dietary preferences and osteoarthritis in European populations,in order to provide a theoretical basis for the prevention of osteoarthritis and to provide reference data for the identification of high-risk groups for hip and knee osteoarthritis in China.METHODS:A total of 20 dietary preference genetic statistics datasets were selected to screen for exposure factor-related instrumental variables.The dataset for osteoarthritis was selected for the ending.After exclusion of the instrumental variables related to confounders,the two-sample Mendelian randomized causal association analysis was conducted mainly by inverse variance weighted analysis,and other four statistical methods were used as supplements.Sensitivity test was performed for the results.RESULTS AND CONCLUSION:(1)The results of the inverse variance weighted analysis showed that preference for barbecue(OR=1.204,95％CI:1.058-1.370,P=0.005),beef(OR=1.167,95％CI:1.034-1.317,P=0.012),chicken(OR=1.399,95％CI:1.119-1.749,P=0.003),pork chops(OR=1.218,95％CI:1.039-1.427,P=0.015)and coffee(OR=1.133,95％CI:1.037-1.238,P=0.006)were risk factors for osteoarthritis of the knee and hip joints,vegetables(OR=0.893,95％CI:0.827-0.964,P=0.004),and vinegar(OR=0.897,95％CI:0.812-0.991,P=0.032)were protective factors for knee-hip osteoarthritis.(2)The results of the sensitivity analysis showed that the instrumental variables included in the analysis without horizontal pleiotropy and bias,and the corresponding inverse variance weighted analysis of effects model was used according to the results of the heterogeneity analysis.(3)The results of this study provide certain reference value in the research on the relationship between dietary preferences and hip and knee osteoarthritis,but only included human whole genome association study data from European populations,and the validity of the research results in other races remains to be tested.Moreover,no stratification was performed on gender,age and other health status.It is difficult to completely rule out the bias from population stratification in the research results.In the future,larger-scale and more finely classified sample data are still needed to carry out relevant causal relationship research.

Objective:To explore the effects of essential tremor(ET)on the mitochondrial morphology of GABAer-gic and glutamatergic neurons in the inferior olive(IO).Methods:The ET mouse model was established via intraper-itoneal injection of harmaline.Twelve 8-week-old male C57BL/6J mice were randomly divided into saline control group and harmaline treatment group(HA).Behavioral tests,including open field test,rotarod test,balance beam test,and tremor scoring,were conducted to assess the behavior of mice.Using genetic engineering technology and the CRISPR/Cas9 system,we designed and generated 6 male GAD2-Mito-GFP mice and 6 male VGLUT2-Mito-GFP mice,all being 8-week-old.The mice of each transgenic line were randomly divided into Control and HA group.Immunofluorescence staining was used to analyze the expression of c-FOS positive cells in the IO of both the Control and HA groups,and to classify different types of neurons.Mitochondrial network analysis(MiNA)was performed to quantitatively analyze the area,mean aspect ratio,branch length,and other of mitochondria in different types of neurons in the IO under ET con-ditions.Results:Compared to the Control group,the HA group exhibited motor abnormalities and significant tremors.Immunofluorescence results showed a significant increase in the number of c-FOS positive cells in the IO,primarily in GABAergic neurons.MiNA results revealed that the mitochondria of GABAergic neurons showed increased area,branch length diameter,demonstrating irregular morphology.Conclusion:ET induces activation of GABAergic neurons in the IO and leads to more prominent mitochondrial morphological changes.This provides a new perspective for further inves-tigation of the pathogenesis of essential tremor and its relationship with mitochondrial.
