According to the Qi-blood-body fluid theory and the association between the spleen in visceral manifestation theory of traditional Chinese medicine （TCM） and mitochondria in modern cellular biology， it is proposed that the role of the spleen in generating and transforming Qi and blood is analogous to the energy-producing function of mitochondria—both serving as fundamental power sources for vital activities of the human body. The spleen governs transportation and transformation， playing a critical role in energy metabolism and the digestion and absorption of nutrients. Similarly， mitochondria are vital for maintaining physiological functions such as cellular energy supply， cell survival， and overall human metabolism. Furthermore， spleen deficiency is closely linked to mitochondrial dysfunction. Accordingly， mitochondrial energy conversion and substance metabolism are regarded as the microscopic essence of the spleen's function in transportation and transformation. Spleen deficiency and mitochondrial dysfunction contribute to the formation of pathological products such as phlegm-turbidity and blood stasis. This aligns with the pathogenesis of chronic obstructive pulmonary disease （COPD）， with Qi deficiency as the root cause and phlegm-turbidity and blood stasis as the manifestations. Therefore， the integrative treatment of COPD should follow the therapeutic principle of invigorating the spleen and reinforcing healthy Qi， while also resolving phlegm and removing blood stasis to address both root cause and manifestations. This approach can improve the mitochondrial function， regulate energy metabolism， and reduce oxidative stress levels to alleviate COPD symptoms， slow down disease progression， and improve prognosis. By integrating the holistic concept of TCM with molecular mechanisms of modern medicine， this paper explores the pathogenesis and therapeutic principles of COPD from the spleen-mitochondria correlation. It not only provides a new direction for the modern development of TCM and the integration of Chinese and Western medicine but also offers a theoretical foundation for the integrated treatment of chronic， complex age-related diseases.

For a long time， simple asymptomatic renal hematuria has not been taken seriously. Current studies have confirmed that renal hematuria is a risk factor for the progression of renal function， but there is no effective treatment available. Because asymptomatic renal hematuria is highly concealed and lacks typical symptoms， individualized syndrome differentiation in traditional Chinese medicine （TCM） is difficult， making it a challenge in clinical diagnosis and treatment. Although TCM has a long history and solid theoretical basis in the treatment of hematuria， it urgently needs to break through the bottleneck of traditional syndrome differentiation. Based on classical TCM theories， research achievements in modern constitution studies， and relevant clinical and pathological evidence， this article focuses on the decisive influence of age on constitution distribution and its regular association with the evolution of core syndromes， and constructs a three-dimensional diagnostic and therapeutic system of "age-constitution-syndrome". It reveals that the syndrome manifestations of asymptomatic renal hematuria are profoundly shaped by constitution， and that constitution shows a group distribution pattern with age-children often present with deficiency of lung and spleen Qi combined with wind-heat， young and middle-aged individuals often present with deficiency of liver and kidney Yin combined with deficient fire and stasis heat， and elderly individuals often present with deficiency of spleen and kidney combined with cold-dampness and stasis obstruction. By analyzing the common pathogenic mechanisms， outcome characteristics， and internal mechanisms among different age groups， this study provides a basic syndrome framework and core intervention strategies for specific populations in clinical practice， offering a new evidence-based approach to addressing the dilemma of “no identifiable syndrome”.

Objective To investigate the mechanisms by which Porphyromonas gingivalis(P.gingivalis)promotes the malignant progression of oral squamous cell carcinoma(OSCC)through the recruitment of chemokine receptor 6-positive(CCR6+)regulatory T cells(Treg)in the tumor microenvironment(TME).Methods The Cancer Genome Atlas(TCGA)database was used to analyze the correlation between chemokine ligand 20(CCL20),CCR6,and Treg.The Treg enrichment index and the expression levels of interleukin(IL)-10 and tumor necrosis factor β1(TGF-β1)were assessed in the high CCR6 expression group of OSCC patients.C57BL/6 mice were randomly assigned to a control group and an experimental group(n=6 in each group).The control group received a single injection of 100 μL SCC7,a mice head and neck squamous carcinoma cell line,while the experimental group received a single injection of 100 μL mixture of SCC7 cells and P.gingivalis in the cheek.After two weeks,the mice were sacrificed,and immunohistochemistry was performed to assess the expression levels of CCR6 and forkhead box protein 3(FOXP3)in OSCC.Flow cytometry was performed to analyze the effects of P.gingivalis on OSCC malignant biological behavior,CCR6+Treg cells,and the immune microenvironment.Results Bioinformatics analysis revealed a correlation between CCL20,CCR6,and Treg(r=0.373,P＜0.0001).OSCC patients with high CCR6 expression showed higher Treg enrichment scores and increased IL-10 expression.Animal experiments showed that P.gingivalis promoted the increase in the tumor volume(mm3)(0.294±0.105 in the control group and 0.526±0.101 in the experimental group,P＜0.01)and mass(mg)(206.200±53.950 in the control group and 376.000±119.200 in the experimental group,P＜0.01)in mice with OSCC.Immunohistochemistry confirmed a correlation between CCR6 and FOXP3(r=0.659,P＜0.05),and P.gingivalis promoted the expression of CCR6 and FOXP3.Flow cytometry analysis showed that P.gingivalis increased the proportion of CCR6+Treg(％)(13.780±1.506 in the control group and 18.260±2.257 in the experimental group,P＜0.01)and decreased the proportion of CD8+T cells(％)(27.120±1.647 in the control group and 21.060±3.148 in the experimental group,P＜0.01)in OSCC,thereby promoting the formation of a immunosuppressive microenvironment.Conclusion P.gingivalis promotes the malignant progression of OSCC by recruiting CCR6+Treg cells to form an immunosuppressive TME.

Objective To characterize the clinical features of the group of gout patients to facilitate earlier identifi-cation,and optimize the diagnosis and treatment of the condition.Methods The retrospective study analyzed 24 gout patients with shoulder joint(s)involved and consulted by physicians of Peking Union Medical College Hospital from March 2021 to April 2025,while 70 outpatient gout patients matched by clinical course duration and sex were enrolled as control group.Clinical data including medical history,laboratory tests,therapeutic interventions.Prog-nosis was systematically collected to delineate the distinctive clinical manifestations of the patients.Results All 24 gout patients with shoulder joints involved were male,aged(43.16±13.13)years and had an average BMI of 27.70±4.63.The duration of gout was 8(5,12)years while of those patients had an early onset before 30 years old.The maximal serum uric acid concentration was(754.15±175.79)μmol/L.It was shown by case review that 16.67％of the patients were asymptomatic,and 79.17％suffered from shoulder pain.A quarter of the patients developed subcutaneous tophi.All the patients affected(P＜0.05).The affected joints ascended from lower extremities to the upper averagely took 4.72±2.80 years and had heavier burden of hyperuricemia(P＜0.05),while no significant difference was found in renal function and inflammation level.Conclusions Gout patients with shoulder joints involvement are older and have atypical manifestation.The diagnosis needs support of imaging or ar-throcentesis.

Objective Chronic gouty arthritis(CGA)can lead to severe bone erosion resulting in joint destruction,which significantly decreases the life quality and prognosis of CGA patients.Osteoclasts play an important role in this course.We aim to investigate the effect of interleukin-17A(IL-17A)on osteoclast formation in vitro in patients with chronic gouty arthritis(CGA)and its potential mechanism.Methods Osteoclasts induced in vitro from pe-ripheral blood mononuclear cells(PBMC)of healthy controls(HC)and CGA patients were studied.CGA-derived osteoclasts were divided into four groups:untreated group,IL-17A-treated group,carbonyl cyanide 3-chlorophenyl-hydrazone(CCCP)group,and mitochondrial division inhibitor-1(Mdivi-1)group.Tartrate-resistant acid phospha-tase(TRAP)staining was used to observe and compare osteoclastogenesis between HC and the untreated group.Western blot was performed to detect mitophagy levels and the expression of key osteoclast differentiation factors.Results Compared with healthy controls,CGA patients showed higher osteoclastogenesis(P＜0.01).Compared with the untreated group,the IL-17A-treated group showed up-regulated expression of key osteoclast transcription factors and decreased mitophagy levels(P＜0.05).Intervention with 10 nmol/L and 15 nmol/L Mdivi-1 significantly promoted the expression of key osteoclast transcription factors(P＜0.01).Conclusions IL-17A promotes osteoclast formation in vitro in CGA patients,and its mechanism may be related to decreased mitophagy levels.

Objective To determine the intrahepatic portal blood flow distribution by using dynamic contrast-enhanced CT(DCE-CT)scan,and to evaluate its application value in preventing overt hepatic encephalopathy(OHE)after transjugular intrahepatic portosystemic shunt(TIPS).Methods The clinical data of 110 patients with digestive tract hemorrhage due to cirrhotic portal hypertension,who received TIPS at Henan Provincial Hospital of Traditional Chinese Medicine of China from July 2017 to November 2023,were retrospectively analyzed.Preoperative DCE-CT was performed to evaluate the type of intrahepatic portal blood flow distribution.In patients with different types of intrahepatic portal blood flow distribution,the incidence of post-TIPS OHE was compared between the patients receiving portal vein left branch shunting and the patients receiving portal vein right branch shunting.Results In patients with the right splenic vein type,the incidences of post-TIPS OHE in left portal branch shunting and right portal branch shunting were 58.3％and 21.1％respectively,and the difference was statistically significant(P=0.022).In patients with the left splenic vein type and the diffuse distribution type,there was no statistically significant difference in the incidence of post-TIPS OHE between left portal branch shunting and right portal branch shunting(P=0.246 and 0.846 respectively).Further subgroup analysis results showed that the incidences of OHE in patients receiving splenic vein dominant branch shunting and in patients receiving superior mesenteric vein dominant branch shunting were 20.8％and 57.9％respectively,and the difference was statistically significant(P=0.008).Conclusion Pre-TIPS DCE-CT evaluation of intrahepatic portal blood flow distribution and intraoperative selective portal vein branch shunting can reduce the risk of postoperative OHE to a certain extent.

Objective: To explore the changes of mechanosensitive channels Piezos (Piezo 1 and Piezo 2) in neurogenic bladder (NB) of young rats and their effects，so as to provide reference for clinical search of new therapeutic targets. Methods: A total of 30 female young SD rats were divided into 5 groups based on random number table method：sham operation group (sham)，2-week nerve transection group (NB-2W)，6-week nerve transection group (NB-6W)，2-week nerve transection + Piezos inhibitor group (NB-P-2W) and 6-week nerve transection + Piezos inhibitor group (NB-P-6W)，with 6 rats in each group.The NB models were constructed by transecting the L6 and S1 spinal nerves of young rats.The NB-2W and NB-6W groups were not intervened after modeling，while the NB-P-2W and NB-P-6W groups were intraperitoneally injected with Piezos inhibitor GsMTx4 (10 mg/kg) every 2 days after modeling.Bladder cystometry and ultrasound were performed after 2 and 6 weeks of transection.The expressions of Piezos and fibrosis-related indexes (Collagen Ⅰ and α-smooth muscle actin) were detected in bladder tissues. Results: The results of bladder cystometry showed that the basal bladder pressure in NB-2W group was significantly increased，while it was slightly decreased but was still higher in NB-6W group than in the sham group (P<0.05).Basal bladder pressure was lower in NB-P-2W group than in NB-2W group，but was higher than that in the sham group; basal bladder pressure was lower in NB-P-6W group than in NB-6W group，but higher than that in the sham group (P<0.05).Compared with the sham group，the NB-2W and NB-6W groups had firstly increased and then decreased maximum cystometric capacity (MCC) (P<0.05).Compared with NB-2W group，NB-P-2W group had lower bladder leakage point pressure (BLPP)，but higher MCC and bladder compliance (BC) (P<0.05).Compared with NB-6W group，NB-P-6W group had significantly lower BLPP but higher MCC and BC (P<0.05).HE and MASSON staining and ultrasound results showed that，with the extension of nerve transection time，bladder fibrosis gradually worsened，the bladder wall became rough and thickened，calculi were visible inside，and hydronephrosis gradually appeared; the degree of fibrosis in NB-P-2W and NB-P-6W groups was less than that in NB-2W and NB-6W groups，and no hydronephrosis was observed in the upper urinary tract.In addition，Western blotting and immunohistochemical results showed that NB-2W and NB-6W groups had significantly higher relative expression levels of Piezos，Collagen Ⅰ and α-SMA than the sham group (P<0.01)，while NB-P-2W and NB-P-6W groups had lower relative expression levels of Piezos,Collagen Ⅰ and α-SMA than NB-2W and NB-6W groups (P<0.01). Conclusion: The increased expressions of mechanosensitive channels Piezos in NB young rats may be involved in the progression of bladder fibrosis，but its mechanism needs further study.

Objective: To explore the core features of trait aggression in children and adolescents, so as to provide a theoretical basis for behavioral interventions targeting the central psychological characteristics of aggression in children and adolescents. Methods: From March to May 2020, a simple random convenience sampling method was employed to recruit 39 165 students from grades 4 to 12 in Sichuan, Chongqing, Guizhou, and Shandong. Data were collected via online questionnaires, with all participants completing the Chinese Version of the Aggression Questionnaire. Psychometric network analysis was utilized for data processing. Results: Trait aggression among Chinese children and adolescents was at a moderately low level. The core nodes of the network structure included physical aggression [if someone intentionally causes trouble for me, I will hit them severely (AGG6); if someone hits me, I will retaliate (AGG11)] and self aggression [When I am very irritable, I think of hurting myself (AGG5); when I am in a bad mood, I engage in behaviors that harm my health, such as overeating (AGG25)]. Across grade levels, core nodes primarily originated from the anger dimension [When I m angry, I feel like a powder magazine that could explode at any moment (AGG13); I can t control my temper (AGG18); I am prone to getting angry when I see things that are not pleasing to the eye (AGG23); I will get angry for no reason (AGG27)]. Except for grades 7 and 9, core nodes in other grades included the verbal aggression dimension [I am prone to arguments with people (AGG22)]. Before grade 8, core nodes incorporated the self aggression dimension (AGG 5, AGG 25); after grade 8, core nodes included the physical aggression dimension [AGG 6, AGG 11, I fight slightly more than others (AGG16), and if people around me make things difficult for me to a certain extent, I will fight with them (AGG26)]. No statistically significant differences were found in the trait aggression network structures across grades, genders, or within gender comparisons of different grades. Conclusion These findings broaden our understanding of aggression in children and adolescents, suggesting that behavioral interventions can effectively reduce aggressive behaviors in this population.

Hepatic osteodystrophy is a common complication in patients with chronic liver disease and is influenced by various risk factors， and it has become one of the important influencing factors for the prognosis of liver transplantation. By analyzing the influencing factors for bone health and bone metabolism during the perioperative period of liver transplantation， this article emphasizes the importance of a comprehensive assessment of bone health and necessary interventions at this stage， with an aim to reduce the risk of postoperative complications and improve the long-term prognosis of patients. A deeper exploration of the association between hepatic osteodystrophy and the prognosis of liver transplantation can help to reveal the key influencing factors for postoperative outcomes， thus providing a theoretical basis for optimizing postoperative management strategies. Furthermore， advances in this research field will offer new insights into the treatment of patients receiving liver transplantation， and it is expected to further improve quality of life and long-term survival rate.
