Sleep disorders are a serious global health problem influenced by neuropsychiatric disorders, diseases, environment, diet, and other factors. Recent studies have revealed that gut microbes (GM) are closely associated with sleep. Their metabolites regulate circadian rhythms, neurotransmitter systems, and other physiological processes through the gut-brain axis, influencing brain homeostasis and contributing to the pathogenesis of insomnia. Suanzaoren decoction (SZRD) is a classic and well-known traditional Chinese medicine (TCM) prescription for the treatment of insomnia. Modern pharmacological research indicates that SZRD can maintain intestinal microbial homeostasis, regulate microbial metabolites, and safeguard the intestinal immune barrier. This review elucidates the pathophysiological interplay between sleep disorders and GM and summarizes the progress of research on SZRD in treating insomnia via the “microbes-gut-brain axis” by regulating intestinal microecology. It is expected to broaden the clinical application of TCM in insomnia treatment and provide a theoretical foundation for pharmacological innovation of classic TCM prescriptions.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Objective To measure the abdominal muscle composition of maintenance dialysis patients using quantitative computed tomography(QCT)and to analyze its relationship with abdominal aortic calcification(AAC).Methods The abdominal CT data of 193 maintenance dialysis patients were analyzed retrospectively and their clinical data were collected.The abdominal muscle composi-tion,including muscle area and muscle fat area,was measured at the middle level of L3 vertebral by QCT.The abdominal aortic calcifica-tion scores(AACs)were calculated using the Agatston method.The groups were grouped according to the quartiles of AACs,and differences in muscle area,muscle fat area and their associated variables were compared between the four groups.The relationship between abdominal muscle composition and AAC was assessed using Spearman rank correlation analysis and partial correlation analysis.Results AACs were positively correlated with age,male,dialysis age,diabetes,hypertension,and abdominal muscle fat area(r=0.555,0.172,0.192,0.348,0.335,0.358,all P<0.05),while no significant correlation was found with abdominal muscle area.A partial correlation analysis controlling for age,sex,dialysis age,hypertension and diabetes showed that AACs were still positively correlated with abdominal muscle fat area(r=0.183,P=0.012).Conclusion Abdominal muscle fat area in maintenance dialysis patients is positively associ-ated with the degree of AAC,and high abdominal muscle fat area is a risk factor for AAC.Enhanced muscle exercise may prevent the risk of vascular calcification in dialysis patients.

To clarify the content characteristics of mineral elements in different Artemisia argyi germplasm resources and their relationship with the quality properties of Artemisiae Argyi Folium, this study measured the content of 10 mineral elements including nitrogen(N), phosphorus(P), potassium(K), calcium(Ca), magnesium(Mg), aluminum(Al), manganese(Mn), iron(Fe), copper(Cu), and zinc(Zn) in 100 Artemisia argyi germplasm samples. Besides, their relationship with the quality properties of Artemisiae Argyi Folium was explored by correlation analysis, path analysis, and cluster analysis. The results demonstrated that the variation coefficient of the 10 mineral elements in Artemisiae Argyi Folium ranged from 12.23% to 64.38%, and the genetic diversity index from 0.97 to 3.09. The genetic diversities of N, P, and Zn were obvious. As revealed by the correlation analysis, N, P, and K showed strong positive correlations with each other. Except that Mg and Al were negatively correlated, Ca, Mg, Al, Mn, Fe, Cu, and Zn were positively correlated. The correlation analysis of mineral elements with the quality properties of Artemisiae Argyi Folium proved the significant correlations of 17 pairs of characters. According to the path analysis, P, K, Ca, and Mn greatly affected the yield of Artemisiae Argyi Folium, P, K, and Mg the output rate of moxa, N, P, and K the content of total volatile oil, P and K the content of eucalyptol, and P, K, and Ca the content of eupatilin. The 100 germplasm samples were clustered into three groups. Specifically, in cluster Ⅰ, the enrichment capacity of P, K, and Mg elements was strong, and the comprehensive properties of mineral elements were better, implying good development potential. Ca, Mn, Fe, and Zn elements in cluster Ⅱ and N and Al in cluster Ⅲ displayed strong enrichment capacities. This study has provided new ideas for resource evaluation and variety breeding of A. argyi and also reference for fertilizer application.

Objective To investigate the relationship between peripheral inflammatory cytokines and anxiety symptoms in patients with the first?episode generalized anxiety disorder. Methods 48 patients diagnosed with the first?episode generalized anxiety disorder according to ICD?10 criteria and 48 healthy sub?jects were recruited. Peripheral levels of IL?1, IL?2, IL?4, IL?5, IL?6, IL?8, IL?10, IL?12p70, GM?CSF and IFN?γ of both groups were evaluated by enzyme?linked immunosorbent assay ( ELISA) ,and CRP was evalua?ted by immunoturbidimetric method. Generalized Anxiety Disorder Scale( GAD?7) and State?Trait Anxiety Inventory ( STAI ) were used to assess the levels of overall anxiety, state anxiety and trait anxiety. Results The levels of CRP ( ( 1. 19 ± 0. 80 ) mg/L vs ( 0. 68 ± 0. 70 ) mg/L, t=3. 31 ) , IL?1α( ( 70. 34 ± 3.60)pg/ml vs (16.94±3.42)pg/ml, t=74.50),IL?2((7.25±3.42)pg/ml vs (4.95±2.31)pg/ml, t=3.85), IL?4((102.02±73.14)pg/ml vs (75.55±32.78)pg/ml, t=2.29),IL?6((12.55±2.37)pg/ml vs (2.71±1.35) pg/ml, t=14.79),IL?8((44.64±16.21)pg/ml vs (35.69±11.70)pg/ml, t=3.10),IL?12((18.16±24.17) pg/ml vs (10.82±4.72)pg/ml, t=2.06),IFN?γ((23.32±15.52)pg/ml vs (16.48±6.80)pg/ml, t=2.79), GM?CSF((19.07±11.12)pg/ml vs (13.40±8.54)pg/ml, t=2.80) in patients with the first?episode general?ized anxiety disorder were significantly higher than normal controls(P<0.05) . Both SAI and TAI had signifi? cantly positive correlation with the levels of IL?1α, IL?2, IL?6, IL?8, IL?12, IFN?γ and GM?CSF ( r=0.24?0.76, P<0.05) . Conclusion The levels of some peripheral inflammatory cytokines in patients with the first?episode generalized anxiety disorder are significantly increased,and they have positive correlation with gener?al anxiety,state anxiety and trait anxiety,which may suggest some immune system defects in the patients.

Objective To investigate the regulatory effects of glucocorticoids on the local renin-angiotensin system in osteoblasts by using MC3T3-E1 cells.Methods Cellular immune histochemistry was carried out to observe the renin-angiotensin system in osteoblasts.And then after 12-hour culture in serum-free solution,MC3T3-E1 cells were divided into four groups:control,dexamethasone (DXM),dexamethasone + mifepristone (DXM+MIF)and mifepristone (MIF).Components of the renin-angiotensin system including angiotensin type 1 receptor (AT1R),angiotensin type 2 receptor (AT2R)and angiotensin converting enzyme (ACE)in osteoblasts were detected at the mRNA and protein levels using Western blot and PCR.The activity of ACE was also measured after 36-hour intervention.Results The results of immunohistochemistry showed that AT1R,AT2R and ACE were all expressed in osteoblasts.The activity of ACE increased obviously after dexamethasone intervention compared with that in the control group,which was blocked by mifepristone.The mRNA levels of AT1R,AT2R and ACE were increased by dexamethasone compared with those in the control group,which was inhibited by mifepristone.The protein levels of AT1R,AT2R and ACE were enhanced by dexamethasone compared with those in the control group, which was blocked when the cells were co-intervened with mifepristone.However,ACE activity and the mRNA and protein levels of AT1R,AT2R and ACE did not change when the cells were intervened with mifepristone alone (P>0.05).Conclusion The local renin-angiotensin system in osteoblasts is activated by dexamethasone through glucocorticoid receptors on osteoblasts,which may be one of the pathogenesis of glucocorticoid-induced osteoporosis.

Objective To explore the feasibility of building tissue engineered cartilage by bone marrow stromal cells and pbotografting modified copolymers of 3-hydroxybutymte and 3-hydroxyvalerate.Methods Sheep BMSCs were seeded in three-dimensional photografting modified PHBV scaffoids.Twenty-four hours later.composites were cultured with ehondrogenically inductive medium(DMEM)containing TGF-B(10 ng/m1),IGF-1(150 ng/m1)and 20% fetal bovine serum.Three weeks later,the constructs were evaluated by scanning electron microscopy(SEM)and light microscopy with alcian blue,safrine 0 and type Ⅱ collage immunohistochemical staining.GAG contents of constructs were determined by DMB(1,9-dimethylmethylene blue)binding assay at weekly intervals up to 3 weeks.The composites were implanted subcutaneously in sheep abedoml and were evaluated macroscopically and bistologically at 4 weeks postoperatively.Results SEM photograph showed.after one week culture,cell morphology changed from fibroblast-like elongated spindle to the flat rounded like chondrocytes,and the extra cellular matrix also increased obviousl~.Furthmore,with the culture time extension,this change were more evident.HE staining showed that cells filled all the inter-connected pores in the constructs.And more cells were observed in the outer layer of the constructs.ECM(extraeellular matrix)Was strongly positive by Aleian blue,Safrine O staining and type Ⅱ collage immunohistechemical staining.DMB binding assay revealed that the induced BMSCs GAG secretion(1306.7±192.3)wag significantly higher than BMSCs(205.0±26.2)(P<0.001),but it was significantly lower than passage 2 ehondrocytes(1969.2±235.3)(P<0.001).Saltine O and type Ⅱ collage immunohistochemical staining were positive in constructs implanted subcutaneously.Conclusion Tissue engineered cartilage could be obtained using BMSCs and photografting modified PHBV,but there are still gaps physiologically between the constructs and the nature cartilage.
