Objective:To explore the relationship between depression, perfectionism and self-injurious function in adolescents with self-injury.Methods:A total of 6 149 adolescents from two middle schools were selected by multi-stage random sampling method to conduct a cross-sectional investigation, and 530 cases with self-injurious behaviors were screened out as the self-injury group, while the remaining 5 619 students served as the non-self-injury group.The self-rating depression scale, the Chinese-revised Frost multidimensional perfectionism scale, and the Ottawa self-injury inventory Chinese revised version were used for investigation.SPSS 24.0 software was used for descriptive statistics and Spearman correlation analysis, and the PROCESS 4.1 macro program was used for mediating effect test(model 4)and moderating effect test(model 7).Results:(1)The incidence of self-injury among adolescents was 8.62%(530/6 149), which was significantly different in gender( χ2=50.942, P<0.01) and grade( χ2=37.401, P<0.01). (2)The scores of depression(48(41, 55)) and maladaptive perfectionism(64(53, 76)) in the self-injury group were higher than those in the non-self-injury group(36(29, 43), 49(35, 61)), and the differences were statistically significant( Z=-23.233, -18.599, both P<0.01). (3)Adolescents with self-injury mostly had external emotion regulation(70.38%(373/530)) as the dominant function.(4)The results of Spearman correlation analysis showed that self-injurious function was significantly and positively correlated with depression( r=0.382, P<0.01) and maladaptive perfectionism( r=0.356, P<0.01), and depression was significantly and positively correlated with maladaptive perfectionism( r=0.352, P<0.01). (5)Maladaptive perfectionism partially mediated the relationship between depression and self-injurious function( β=0.086, P<0.001), and the mediating effect accounted for 21.88%(0.086/0.393)of the total effect.(6)Gender moderated the first stage of the mediation pathway(depression→maladaptive perfectionism)( β=0.180, P<0.05), which indicated that depression had a stronger predictive effect on maladaptive perfectionism in women( βsimple=0.105, 95% CI=0.063-0.154, P<0.05). Conclusion:In the prediction of depression on self-injurious function, maladaptive perfectionism plays a partial mediating role, and this mediating effect is moderated by gender.

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.

Breast cancer remains a substantial threat to women's health and is one of the most prevalent malignant tumors in women.Because breast cancer onset is closely associated with female physiological characteristics,this article proposes that breast cancer be classified as a"women's miscellaneous diseases"and that its treatment be explored from this perspective.Drawing from Chapter 8 on Golden Chamber of Prescriptions for Miscellaneous Diseases in Women of Synopsis of Golden Chamber,the initial pathogenesis of breast cancer is associated with"emotional stress,improper lifestyle,deficiency,cold,and stagnation."The fundamental mechanism behind its formation is"blood cold accumulation and hardened masses."Specifically,emotional imbalance and improper lifestyle habits contribute to the combined invasion of the uterus by"deficiency,""accumulated cold,"and"stagnant qi."Over time,"cold-blood stasis accumulates at the uterine ostium,"and the cold and the stasis ascends from the uterus along the thoroughfare and conception vessels,obstructing the breast collaterals.This combination of yang qi stagnation and yin cold congealment,ultimately leads to the development of breast cancer.The treatment principle should focus on"activating yang and dispersing cold."A therapeutic approach centered on Wenjing Decoction combined with Xiaoyao Powder can be adapted based on the stage and type of breast cancer while also considering the dynamic interplay between pathogenic factors and healthy qi,along with shifts in deficiency and excess patterns of disease.By adhering to the principles of consistency and flexibility and integrating disease and syndrome differentiation,the goal is to develop precise and personalized treatment strategies to improve clinical outcomes.

Objective:To explore the trends and distribution of liver cancer between sexes, ages, and urban-rural areas in Tianjin, China from 1999 to 2021, and provide data for targeted prevention and control strategies of liver cancer in Tianjin.Methods:Liver cancer mortality data of Tianjin during 1999-2021 were from the Tianjin population based mortality surveillance system maintained by the Tianjin Centers for Disease Control and Prevention (CDC), and the population data of permanent Tianjin residents were from Tianjin Municipal Public Security Bureau. Liver cancer mortality, years of life lost (YLL), years lived with disability (YLD), and disability adjusted life years (DALY) were calculated using the cause of death surveillance data collected by Tianjin Centers for Disease Control and Prevention. The distributions of these data among residents of different sexes, ages, and regions were analyzed. Segi's world standard population was used for standardization. Joinpoint regression was used for trend analysis on the mortality rate of liver cancer and the disease burden.Results:The liver cancer mortality rate in Tianjin decreased by 46.75% from 1999 to 2021, with distinct phased characteristics. From 1999 to 2010, the age-sex-standardized mortality rate (SMR) decreased from 12.62/100 000 to 11.64/100 000 with an annual percent change (APC) of -1.32% ( P=0.003). From 2010 to 2021, the SMR decreased from 11.64/100 000 to 6.72/100 000 (APC=-3.89%, P＜0.001). The age-sex-standardized DALY rates(SDR) decreased by 50.63% from 1999 to 2021, also with distinct phased characteristics. From 1999 to 2010, the SDR decreased from 388.67/100 000 to 349.38/100 000 (APC=-1.35%, P=0.002). From 2010 to 2021, the SDR decreased from 349.38/100 000 to 191.88/100 000 (APC=-4.43%, P＜0.001). The liver cancer mortality rate declined most rapidly in the age group under 45 years; the APC for those under 35 years was -5.07% ( P＜0.001), and for those aged 35-44 years, the APC was 0.63% ( P=0.707) and -8.21% ( P＜0.001) before and after 2007, respectively. Both SMR and SDR were significantly higher in males than in females ( P＜0.01). Both SMR and SDR were significantly higher in urban areas than in rural areas from 1999 to 2007 ( P＜0.05), but they became similar after 2008. Liver cancer DALY are predominantly YLL, accounting for 99%. The median age of liver cancer deaths in Tianjin during 1999-2021 was 64-68 years old, with males lower than females ( P＜0.05), and rural areas lower than urban areas ( P＜0.05), generally showing an increasing trend (1999-2014: APC=0.11%, P=0.047; 2014-2021: APC=0.51%, P=0.005). Conclusions:Liver cancer mortality rate and disease burden decreased from 1999 to 2021 in Tianjin, with an especially accelerated decline after 2010. Further efforts to reduce liver cancer mortality in Tianjin are needed, and special attention should be focused on the elderly, male, and rural residents.

ObjectiveTo investigate whether paeonol exerts a protective effect on mice with alcoholic liver injury by regulating the takeda G-protein-coupled receptor 5 （TGR5）/protein kinase A （PKA）/cAMP response binding element （CREB） signaling pathway mediated by Eubacterium. MethodC57BL/6 mice were randomly divided into five groups： normal group， model group， paeonol group （480 mg·kg^-1）， antibiotic group （Abs group）， and antibiotic + paeonol group. Lieber-DeCarli liquid was used to feed C57BL/6 mice on the second day of modeling for 10 days. The blood lipids， liver function， inflammatory factors， and oxidative stress levels in mice were measured. Hematoxylin-eosin staining （HE） and oil red O staining were used to observe the morphological changes and fat accumulation in liver tissue. 16S rDNA sequencing was used to detect the diversity of intestinal microbiota in the blank， model， and paeanol groups. Western blot was used to detect the effect of paeonol on the expression levels of protein related to the signaling pathway of atresia band protein 1 （ZO-1）， Claudin-1， and TGR5/PKA/CREB in mouse ileal tissue. ResultCompared with those in the blank group， the blood lipids， liver function， oxidative stress levels， and the expression of inflammatory factors in the model group increased （P<0.01）， and the liver fat vacuoles were obvious. The ileal mucosa was seriously damaged， and the protein contents of ZO-1， Claudin-1， and TGR5/PKA/CREB in the ileal tissue decreased significantly （P<0.01）. The intestinal microbiota changed， and the proteobacteria phylum increased significantly. The ratio of Bacteroidetes to Firmicutes decreased. The relative abundance of Dubosiella newyorkensis， Lactobacillus， Bifidobacterium， and other genera decreased， while the relative abundance of Escherichia-Shigella， Morganella， Providencia， and Proteus increased significantly. Compared with the model group， paeonol significantly reduced the blood lipids， liver function， oxidative stress levels， and expression of inflammatory factors in mice with alcohol diet-induced liver injury （P<0.05）， decreased liver fat vacuoles， improved and restored the ileal intestinal barrier， and restored the normal structure of hepatocytes and ileal cells. The intestinal microbiota disorder caused by alcohol was improved， and the relative abundance of beneficial bacteria such as Eubacterium spp. was increased. The protein expression levels of ZO-1， Claudin-1， and TGR5/PKA/CREB in ileal tissue were increased （P<0.05）. ConclusionPaeonol has a protective effect on alcoholic liver injury in mice， and the mechanism of action is achieved by regulating the Eubacterium-mediated TGR5/PKA/CREB signaling pathway to ensure anti-inflammatory effect and improve the intestinal barrier.

The anterior cruciate ligament (ACL) injury is a common sports injury that has a significant impact on knee function and patients′ mobility. With the popularity of national fitness campaign in China, the incidence of ACL injury is increasing year by year. Currently, there still lacks clinical standards or guidelines on how to choose appropriate treatment methods, surgical plans and rehabilitation protocols for ACL injury. In order to timely reflect the new treatment concept of ACL injury, standardize its diagnosis and treatment and improve the curative effect, the Sports Medicine Society of Chinese Research Hospital Association and the Editorial Board of Chinese Journal of Trauma organized domestic orthopedic and sports medicine experts to formulate the "clinical evidence-based guideline for the diagnosis and treatment of anterior cruciate ligament injury (2022 version)" based on the level of evidence-based medicine and in compliance with the principle of scientificity, practicability and advancement. The present guideline includes 12 recommendations for the diagnosis, treatment and rehabilitation of ACL injury in order to provide guidance and assistance for the clinical diagnosis and treatment of ACL injury in China.
