AIM: To investigate the distribution characteristics of pathogens in patients with post-traumatic infectious endophthalmitis(PTIE)and their relationship with serum levels of macrophage inflammatory protein 1α(MIP-1α), heat shock protein 70(HSP70), and soluble triggering receptor expressed on myeloid cells 1(sTREM-1).METHODS:A total of 157 patients with PTIE from the Handan City Eye Hospital(The Third Hospital of Handan)from May 2023 to May 2025 were selected as the study group. They were divided into a good prognosis group and a poor prognosis group based on their uncorrected visual acuity at discharge. Meanwhile, 157 patients with ocular trauma but without endophthalmitis during the same period were selected as control group 1, and 157 healthy volunteers who underwent physical examinations during the same period were selected as control group 2. Aqueous humor and vitreous fluid samples were collected from the study group to detect the distribution of pathogens. The levels of serum MIP-1α, HSP70, and sTREM-1 were measured using the enzyme-linked immunosorbent assay. Multivariate Logistic regression analysis was performed to identify risk factors for poor prognosis. The predictive value of serum MIP-1α, HSP70, and sTREM-1 levels for poor prognosis was evaluated using receiver operating characteristic(ROC)and decision curve analysis(DCA).RESULTS: The general data of the participants in the three groups was comparable. A total of 173 pathogens were detected in the 157 patients with PTIE, with Gram-positive bacteria being the predominant type. The levels of serum MIP-1α and sTREM-1 in the study group were higher than those in control groups 1 and 2, while the level of HSP70 was lower than those in control groups 1 and 2(all P<0.05). There were no significant differences in the levels of serum MIP-1α, HSP70, and sTREM-1 between control groups 1 and 2(all P>0.05). In the poor prognosis group, the time of wound suture was ≥24 h, the wound location was in zones II/III, the type of trauma was rupture, the proportion of rupture injuries, and the levels of serum C-reactive protein, MIP-1α, and sTREM-1 were higher than those in the good prognosis group, while the level of HSP70 was decreased(all P<0.001). Multivariate Logistic regression analysis showed that the time of wound suture, wound location, type of trauma, C-reactive protein, MIP-1α, HSP70, and sTREM-1 were risk factors for poor visual prognosis in patients with PTIE(all P<0.05). The ROC curve results showed that the combined prediction of serum MIP-1α, HSP70, and sTREM-1 for poor visual prognosis in PTIE patients had an AUC value of 0.965, which was significantly higher than that of individual predictions(ZMIP-1α, ZHSP70, ZsTREM-1=3.628, 4.705, 3.930, all P<0.05). Additionally, the DCA curve showed that the combined prediction had a higher net benefit rate than individual predictions in the high-risk threshold range of 0.03-0.97.CONCLUSION:Gram-positive bacteria are the predominant type of pathogenic bacteria in patients with PTIE, with elevated levels of serum MIP-1α and sTREM-1 and decreased levels of HSP70. The combined detection of these three factors has a high predictive efficacy for visual prognosis in patients.

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.

ObjectiveTo observe the effects of Danggui Shaoyaosan on macrophage polarization and renal inflammation in db/db mice with diabetic kidney disease （DKD）， and to explore its renal protective effects and underlying mechanisms. MethodsEight db/m mice were assigned to the normal group， and forty db/db mice were randomly divided into a model group， low-， medium-， and high-dose Danggui Shaoyaosan groups （8.39， 16.77， 33.54 g·kg^-1）， and an irbesartan group （0.025 g·kg^-1）. All mice were administered treatment by gavage for 12 consecutive weeks. General conditions of the mice were observed during the intervention. At the end of the 12-week intervention， 24-h urine samples were collected using metabolic cages， after which the mice were anesthetized for sample collection. Blood was collected by enucleation and centrifuged to obtain serum for the determination of glycated serum protein （GSP）， serum creatinine （SCr）， blood urea nitrogen （BUN）， total cholesterol （TC）， and triglycerides （TG）. The urinary albumin-to-creatinine ratio （UACR） was measured. Renal pathological changes were observed using hematoxylin-eosin （HE） staining， periodic acid-Schiff （PAS） staining， and Masson staining. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum tumor necrosis factor-α （TNF-α）， interleukin-10 （IL-10）， and monocyte chemoattractant protein-1 （MCP-1） levels. Immunofluorescence （IF） was performed to detect F4/80 expression in renal tissue， and immunohistochemistry （IHC） was used to assess CD206 expression. Real-time quantitative polymerase chain reaction （Real-time PCR） was employed to measure the mRNA expression of TNF-α， IL-10， inducible nitric oxide synthase （iNOS）， and arginase-1 （Arg-1）. Western blot analysis was used to detect the protein expression of iNOS， Arg-1， CD86， and CD206 in renal tissue. ResultsCompared with the normal group， the model group showed increased levels of GSP， UACR， SCr， BUN， TC， and TG， elevated levels of the inflammatory factor TNF-α and the chemokine MCP-1， and decreased IL-10 levels （P<0.01）. Pathological examination revealed glomerular hypertrophy， mesangial cell proliferation with marked mesangial expansion， inflammatory cell infiltration， vacuolar degeneration of renal tubular epithelial cells， prominent glycogen deposition， and increased collagen fiber deposition. In addition， relative F4/80 fluorescence intensity was enhanced， CD206 expression in the glomeruli and renal interstitium was reduced， and TNF-α and iNOS mRNA expression was increased. IL-10 and Arg-1 mRNA expression was decreased， iNOS and CD86 protein expression was increased， and Arg-1 and CD206 protein expression was decreased （P<0.05， P<0.01）. Compared with the model group， the Danggui Shaoyaosan groups and the irbesartan group showed decreased levels of GSP， UACR， SCr， BUN， TC， and TG， reduced serum TNF-α and MCP-1 levels， and increased IL-10 levels. Renal pathological damage was improved to varying degrees. Relative F4/80 fluorescence intensity was reduced， CD206 expression in the glomeruli and renal interstitium was increased， and TNF-α and iNOS mRNA expression was decreased. IL-10 and Arg-1 mRNA expression was increased， iNOS and CD86 protein expression was reduced， and Arg-1 and CD206 protein expression was increased （P<0.05， P<0.01）. ConclusionDanggui Shaoyaosan can improve renal function and alleviate renal pathological damage in db/db mice. Its mechanism may be related to inhibiting M1 pro-inflammatory macrophage polarization， promoting M2 anti-inflammatory macrophage polarization， reducing inflammatory responses， delaying the progression of renal fibrosis， improving renal pathological injury， and thereby exerting renal protective effects.

At present, the treatment of sepsis depends largely on non-specific methods, highlighting an urgent need for novel therapeutic strategies. Stem cells have garnered significant attention in the treatment of various diseases due to their unique biological properties. Stem cells enhance sepsis survival through mechanisms such as reducing bacterial burden, modulating inflammation, and ameliorating organ dysfunction. Recent studies have shown that stem cells can increase the survival rate of sepsis patients through multiple pathways such as reducing the bacterial load of the host, regulating inflammatory homeostasis, and improving multi-organ dysfunction. Their derivatives, exosomes, can also alleviate the imbalanced immune response in sepsis patients. Recent advances in stem cell-based therapies for sepsis were summarized in this paper.

ObjectiveTo explore the mechanism by which Yinchenhao Tang intervenes in α-naphthylisothiocyanate （ANIT）-induced cholestatic liver injury by regulating the Takeda G-protein-coupled receptor 5（TGR5）/NOD-like receptor protein 3（NLRP3）/cysteine aspartate-specific protease-1 （Caspase-1） pyroptosis signaling pathway. MethodsForty male Wistar rats were randomly assigned into blank， model， ursodeoxycholic acid， and Yinchenhao Tang groups. Except the blank group， other groups were treated with ANIT dissolved in olive oil for the modeling of cholestatic liver injury. Ursodeoxycholic acid （0.1 g·kg^-1） and Yinchenhao Tang （9.23 g·kg^-1） were administered by gavage. The blank group and the model group were administrated with the same amount of pure water， once a day for 3 days. The blood and liver tissue samples were collected， and the serum levels of liver function indicators were measured by an automatic biochemical analyzer. Hematoxylin-eosin staining was employed to observe the pathological changes of the liver. The levels of interleukin （IL）-1β and IL-18 in the liver tissue were determined by ELISA. The mRNA levels of IL-1β， IL-18， TGR5， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， Caspase-1， and GSDMD in the liver tissue were assessed by Real-time PCR. The protein levels of TGR5， NLRP3， ASC， Caspase-1， and GSDMD in the liver tissue were determined by Western blot. ResultsCompared with the blank group， the model group showed elevated levels of alanine amino-transferase （ALT）， aspartate transferase （AST）， alkaline phosphatase （ALP）， total bile acid （TBA）， and total bilirubin （TBil） in the serum （P<0.01）， inflammatory cell infiltration， hepatocyte swelling， and bile duct epithelial cell proliferation in the liver， raised levels of IL-1β and IL-18 in the liver tissue （P<0.01）， down-regulated mRNA and protein levels of TGR5 （P<0.01）， up-regulated mRNA levels of IL-18 （P<0.01）， ASC （P<0.01）， Caspase-1 （P<0.01）， GSDMD （P<0.01）， IL-1β （P<0.05）， and NLRP3 （P<0.05）， and up-regulated protein levels of NLRP3 （P<0.01）， ASC （P<0.01）， Caspase-1 （P<0.01）， and GSDMD （P<0.05）. Compared with the model group， the ursodeoxycholic acid group showed declined levels of AST （P<0.01）， TBA （P<0.01）， TBil （P<0.01）， and ALT （P<0.05） in the serum， lowered levels of IL-1β and IL-18 in the liver tissue （P<0.01）， down-regulated mRNA levels of NLRP3 （P<0.01）， Caspase-1 （P<0.01）， GSDMD （P<0.01）， IL-1β （P<0.05）， IL-18 （P<0.05）， and ASC （P<0.05）， up-regulated mRNA and protein levels of TGR5 （P<0.05）， and down-regulated protein levels of NLRP3， ASC， Caspase-1， and GSDMD （P<0.05）. Compared with the model group， the Yinchenhao Tang group showed lowered levels of ALT， AST， ALP， TBA， and TBil in the serum （P<0.01）， declined levels of IL-1β and IL-18 in the liver tissue （P<0.01）， down-regulated mRNA levels of IL-1β （P<0.01）， NLRP3 （P<0.01）， ASC （P<0.01）， Caspase-1 （P<0.01）， GSDMD （P<0.01）， and IL-18 （P<0.05）， up-regulated mRNA and protein levels of TGR5 （P<0.01）， and down-regulated protein levels of Caspase-1 and GSDMD （P<0.05）. The liver tissue of the administration groups showed reduced infiltration of inflammatory cells， reduced swelling of hepatocytes， and alleviated proliferation of bile duct epithelial cells. ConclusionYinchenhao Tang can ameliorate ANIT-induced cholestatic liver injury by regulating the hepatocyte pyroptosis mediated by the TGR5/NLRP3/Caspase-1 signaling pathway.

ObjectiveThis study aims to investigate the mechanism of Yinchenhao Tang （YCHT） in regulating macrophage polarization to alleviate cholestatic liver injury，focusing on the TLR4/NF-κB signaling pathway as the entry point. MethodsCholestasis was induced in Wistar rats through a single gavage of 100 mg·kg^-1 α-naphthyl isothiocyanate （ANIT） dissolved in olive oil. The animals were randomly divided into four groups：Model group，YCHT group，ursodeoxycholic acid （UDCA） group （n=10），and a blank group （n=10） that received only 5 mL·kg^-1 olive oil. The YCHT group received 9.23 g·kg^-1·day^-1 of YCHT by gavage，and the UDCA group was treated with 0.1 g·kg^-1·day^-1 of UDCA suspension. Both the normal and model groups were given an equal volume of normal saline，all for three consecutive days. Serum liver function was assessed using an automatic biochemical analyzer. Hematoxylin-eosin （HE） staining was used to observe liver tissue morphology. Levels of tumor necrosis factor-α （TNF-α），interleukin-1β （IL-1β），transforming growth factor-β （TGF-β），and interleukin-10 （IL-10） were quantified in liver homogenate supernatants via enzyme-linked immunosorbent assay （ELISA）. Western blot analysis measured the relative protein expression of Toll-like receptor 4 （TLR4），nuclear factor-κB （NF-κB），CD206，inducible nitric oxide synthase （iNOS）， CD86，and arginase-1 （Arg-1）. The relative mRNA expression of TLR4/NF-κB，CD206，iNOS，CD86，and Arg-1 in liver tissue was evaluated using real-time quantitative PCR. ResultsCompared with the normal group，the model group exhibited significantly elevated levels of alkaline phosphatase （ALP），total bile acid （TBA），total bilirubin （TBil），aspartate aminotransferase （AST），and alanine aminotransferase （ALT） （P<0.01）. There was a portal area expansion and pronounced inflammatory cell infiltration. The expression of pro-inflammatory markers TNF-α and IL-1β was significantly upregulated （P<0.01），and macrophage markers CD86 and CD206 showed positive expression. Protein and mRNA expressions of iNOS and CD86 were significantly elevated （P<0.01）. The mRNA and protein expressions of the related pathway molecules TLR4 and NF-κB were significantly increased （P<0.01）. Compared with those in the model group， the liver function indicators in the YCHT group showed significant decreases （P<0.05， P<0.01）. The bile duct hyperplasia was significantly alleviated， and the tissue structure became more orderly. The levels of IL-1β and TNF-α were significantly reduced （P<0.01）， while the expression levels of IL-10 and TGF-β significantly increased （P<0.05， P<0.01）. The expression of CD86 significantly decreased （P<0.01）， and the expression of CD206 significantly increased （P<0.01）. The protein and mRNA expressions of iNOS and CD86 significantly decreased （P<0.01）， and those of Arg-1 significantly increased （P<0.01）. The protein and mRNA expressions of CD206 significantly increased （P<0.05， P<0.01）， and the mRNA and protein expressions of related pathway molecules TLR4 and NF-κB significantly decreased （P<0.01）. ConclusionYCHT ameliorates cholestatic liver injury in rats by improving bile metabolism，reducing bile duct dilatation，and mitigating inflammation. These effects are achieved through the inhibition of M1 macrophage activation and the promotion of M2 macrophage polarization，likely via modulation of the TLR4/NF-κB signaling pathway.

Cholestatic liver injury refers to the bile production， secretion， and excretion disorder caused by various reasons. It induces liver injury， metabolic disorders， and dysfunction of the hepatobiliary system， which can further develop into liver fibrosis， cirrhosis， liver failure， and even death. At present， the preferred drug for clinical treatment is ursodeoxycholic acid， which， however， induces adverse reactions and is intolerant in some patients. Yinchenhao Tang is a representative prescription of traditional Chinese medicine for the treatment of jaundice due to Yang jaundice. It has the effects of clearing heat， eliminating dampness， and removing jaundice and has shown good therapeutic effect in long-term clinical application. Modern pharmacological studies have found that this prescription has anti-inflammatory， anti-oxidation， bile acid balance-regulating， hepatocyte apoptosis-inhibiting and other liver-protecting effects. This paper reviews the relevant clinical and animal experimental studies on Yinchenhao Tang in the treatment of cholestatic liver injury in recent years. Yinchenhao Tang can intervene in the progression of cholestatic liver injury by regulating bile acid metabolism and excretion， reducing inflammatory response， inhibiting oxidative stress， alleviating endoplasmic reticulum stress， inhibiting hepatocyte apoptosis， and protecting intestinal mucosal barrier. This paper systematically expounds the molecular mechanisms by which Yinchenhao Tang regulates cholestatic liver injury that are confirmed by current research， aiming to provide reference for the clinical application and in-depth study of Yinchenhao Tang.
