ObjectiveTo investigate the effects of Shengui Jiangtang Formula on insulin resistance and glucose-lipid metabolism in spontaneous type 2 diabetic db/db mice based on the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/forkhead box protein O1 (FoxO1) signaling pathway, and to provide theoretical foundation for its clinical application through fundamental experiments. MethodsA randomized controlled design was employed in this study. Thirty spontaneous type 2 diabetic db/db mice meeting the inclusion criteria (fasting blood glucose >7.0 mmol·L-1 and random blood glucose on a different day≥11.1 mmol·L-1) were selected as the subjects. After stratified block randomization by body weight and blood glucose levels, they were randomly assigned to a model group, a metformin group, and a Shengui Jiangtang formula group, with n=10 per group. Ten db/m mice were used as the normal group. During the 5-week intervention, general indicators (including general condition, fasting blood glucose (FBG), body weight, and food intake) were recorded weekly. An oral glucose tolerance test (OGTT) was performed at week 5. After 5 weeks, serum was collected to measure glucose-lipid metabolism parameters. Liver tissues were analyzed as follows: Histopathology was observed through hematoxylin and eosin (HE) staining, periodic acid-Schiff (PAS) staining, and Oil red O staining. The expression of proteins and genes related to the PI3K/Akt/FoxO1 signaling pathway was quantitatively analyzed using Western blotting (Western blot) and real-time quantitative polymerase chain reaction (Real-time PCR). ResultsGeneral observations: The mice in the normal group were generally healthy, exhibited agile responses and had smooth and glossy fur. Compared with the normal group, the mice in the model group displayed typical symptoms of polydipsia, polyphagia, and polyuria, along with listlessness and rough fur. Their food intake, initial body weight, liver weight, and liver index were all significantly higher than those in the normal group (P<0.01). After 5 weeks of drug intervention, neither the Shengui Jiangtang Formula group nor the metformin group significantly affected the food intake of the model mice. Compared with the model group, no statistically significant difference was observed in liver weight or liver index in the Shengui Jiangtang formula group. Serum biochemical indicators: Compared with the normal group, the model group showed significantly elevated levels of FBG, fasting insulin, homeostatic model assessment of insulin resistance (HOMA-IR), glycosylated serum protein, and blood lipids. After drug intervention, compared with the model group, the Shengui Jiangtang formula group significantly reduced FBG in the model mice (P<0.01). The blood glucose levels at all time points during the OGTT in the Shengui Jiangtang Formula group were lower than those in the model group, with statistically significant differences in the 0 min blood glucose and the area under the curve for glucose compared to the model group (P<0.05). Furthermore, the formula significantly reduced fasting insulin levels, HOMA-IR, and glycosylated serum protein levels (P<0.05). It also showed a tendency to decrease blood lipids, liver enzymes (aspartate aminotransferase, alanine aminotransferase), and blood urea nitrogen levels, and a tendency to increase creatinine levels, although these differences were not statistically significant. Liver histomorphology: HE staining indicated that Shengui Jiangtang formula improved the morphological structure of hepatocytes and attenuated steatosis in diabetic mice. Liver PAS staining showed that it increased hepatic glycogen content and promoted hepatic glycogen synthesis in diabetic mice. Oil red O staining demonstrated that it reduced lipid deposition within hepatocytes. Western blot: Compared with the normal group, the model group showed decreased protein expression of PI3K, Akt, p-Akt, and p-FoxO1, and increased FoxO1 protein expression. Compared with the model group, both the metformin and Shengui Jiangtang Formula groups showed increased protein expression of PI3K, Akt, p-Akt, and p-FoxO1, and decreased FoxO1 protein expression. Real-time PCR: Compared with the normal group, the mRNA expression of PI3K and Akt was downregulated (P<0.05), and the mRNA expression of FoxO1 was downregulated (P<0.05) in the model group. ConclusionShengui Jiangtang Formula can improve insulin resistance and glucose-lipid metabolic disorders in db/db mice. It alleviates hepatic steatosis, promotes hepatic glycogen synthesis, and reduces lipid deposition in these mice. The mechanism by which Shengui Jiangtang Formula improves insulin resistance may be associated with the PI3K/Akt/FoxO1 signaling pathway.

Diabetic foot ulcer (DFU) is one of the most severe and costly complications of diabetes, with its refractory nature largely attributed to the persistent vicious cycle of inflammation and oxidative stress. Conventional single-target therapeutic strategies often fail to effectively break this cycle. Traditional Chinese medicine (TCM), leveraging its unique philosophy of ''holistic regulation and multi-target intervention'', has demonstrated significant advantages in promoting DFU healing. This review introduced a ''systemic intervention'' perspective to systematically elucidate how TCM, through multi-component synergistic networks, precisely deconstructs and intervenes in this pathological loop. Firstly, this study provided an in-depth analysis of how, under hyperglycemic conditions, the crosstalk between the nuclear factor-kappa B (NF-κB) and NOD-like receptor family pyrin domain-containing protein 3 (NLRP3) inflammasome pathways, the imbalance in macrophage polarization and the disruption of redox homeostasis interact to form a self-sustaining vicious cycle that impedes wound repair. Subsequently, the core content systematically discussed the strategies by which TCM breaks this deadlock: (1) Active ingredients from single herbs (e.g., luteolin and astragaloside Ⅳ) can precisely modulate key nodes such as the phosphatidylinositol 3‑kinase/protein kinase B (PI3K/Akt) and TLR4/NF-κB pathways, thereby suppressing inflammation and oxidative stress. (2) Classical compound formulas (e.g., Simiao Yong'an decoction and Taohong Siwu decoction) synergistically improve microcirculation and the immune microenvironment through multi-component cooperation. (3) External preparations (e.g., Shengji Yuhong Ointment and Jinhuang powder) potently exert local anti-inflammatory and pro-repair effects by activating pathways such as nuclear factor erythroid 2-related factor 2/heme oxygenase 1 (Nrf2/HO-1). Collectively, these three modalities embody a synergistic mechanism characterized by ''internal treatment modulating the internal milieu to address the root cause, and external treatment targeting the lesion to alleviate symptoms''.” Existing clinical evidence has confirmed that the aforementioned multi-target interventions can effectively promote healing and improve symptoms. However, this field still faces persistent challenges, including an unclear material basis for the efficacy of compound formulas, and insufficient standardization in quality control and clinical protocols. These challenges stem from the inherent tension between the complex systems-based characteristics of TCM and the requirements of modern standardization. Future efforts urgently require to leverage cutting-edge technologies, such as network pharmacology, spatial multi-omics, and artificial intelligence to propel the paradigm shift in the prevention and treatment of DFU with TCM from ''empirical multi-target approaches'' toward ''precise systems regulation''. This will provide a theoretical foundation for developing innovative strategies for managing difficult-to-heal wounds based on an integrated traditional Chinese and Western medicine approach.

Crohn 's disease (CD) is an intestinal inflammatory disease of unknown etiology, the pathophysiological mechanism is still unclear. The enteric nervous system (ENS) is responsible for the autonomous regulation of intestinal function. Therefore, ENS dysfunction may be the core of the pathophysiological mechanism of CD. Here, we review the pathophysiological mechanism by which ENS contributes to the development of CD, with a focus on the role of aberrant histological manifestations of ENS and plexitis in predicting the recurrence of CD following surgery.

Objective To investigate the factors that influence ocular surface biology and visual acuity in individuals with diabetic dry eye(DDE)and analyze how these factors contribute to changes in visual quality.Methods Based on the disease duration,fasting blood glucose(FBG),and glycated hemoglobin(HbA1c)levels of patients with type 2 diabe-tes mellitus(T2DM),the DDE patients were divided into different groups.Logistic regression analysis was used to identify influencing factors related to ocular surface biology and visual quality in each group of DDE patients.Tear film stability was evaluated based on the tear film rupture time(BUT),Schirmer I test(SIt),and ocular surface disease index(OSDI).Lip-iview? Surface interferometers were used to measure tear film lipid layer thickness(LLT),meibomian gland loss rate(MGP),meibomian gland opening number(MGYLS),and meibomian gland secretion score(MGYSS).Wavefront aber-rometry was used to measure corneal wavefront aberration values at 4 mm and 6 mm pupil diameters.Ocular response ana-lyzer(ORA)was adopted to analyze corneal hysteresis(CH)and corneal resistance factor(CRF).Moreover,ELISA ex-periment to evaluate the trend of changes in inflammatory factors in tears.Results Logistic regression analysis revealed that T2DM duration,smoking history,FBG,HbA1c,total cholesterol(TC),triglycerides(TG),OSDI score,LLT,BUT,SIt,MGP,MGYLS,MGYSS,total higher-order aberrations,spherical aberration,coma aberration,trefoil aberration,tumor necrosis factor-α,interleukin-6,matrix metalloproteinase-9,receptor for advanced glycation end products,and insu-lin were all influencing factors for the risk of DDE(all P<0.05).As the T2DM course prolonged and FBG or HbA1 c levels rose,tear film-related indicators(LLT,BUT,and SIt)and meibomian gland-related indicators(MGYLS and MGYSS)inpa-tients gradually decreased,while OSDI scores and MGP gradually increased(all P<0.05).As the T2DM course prolonged and FBG or HbA1c levels rose,the total higher-order aberrations,spherical aberration,coma aberration,and trefoil aber-ration in DDE patients under 4 mm and 6 mm pupil diameters gradually increased;Meanwhile,best corrected visual acuity,corneal hysteresis,and corneal resistance factor gradually decreased;The contents of tumor necrosis factor-α,interleukin-6,matrix metalloproteinase-9,receptor for advanced glycation end products,and insulin in tears all gradually increased,while mucin-5AC gradually decreased(all P<0.05).Conclusion With the prolongation of T2DM duration and the in-crease of FBG or HbA1c,the ocular surface inflammatory response in DDE patients gradually worsens,corneal biological function decreases,and visual quality deteriorates.Timely systemic and local interventions are of great significance for im-proving dry eye symptoms and visual quality in DDE patients.

Objective:To explore the diagnostic value of the macrophage activation syndrome/systemic juvenile idiopathic arthritis(MS)score in macrophage activation syndrome(MAS)associated with systemic juvenile idiopathic arthritis(sJIA),and to provide a reference for clinical work.Methods:This study was a retrospective case-control analysis,conducted on the patients initially diagnosed as sJIA-associated with MAS and admitted into the Department of Rheumatology and Immunology of Children's Hospital Affiliated to Xi 'an Jiaotong University from July 1st,2016 to June 30th,2023. All of the patients met the diagnostic criteria for patients with MAS associated with sJIA according to the 2016 European Alliance of Associations for Rheumatology(EULAR)/American College of Rheumatology(ACR)/Pediatric Rheumatology International Trials Organization(PRINTO)standards. The basic information at baseline,clinical manifestations,and auxiliary examination results were collected. The MS score was applied to re-evaluate the children diagnosed as sJIA-associated with MAS. When the MS score ≥-2.1,the possibility of sJIA with MAS was high. Thirty cases of sJIA without MAS were randomly selected as the control group.Results:There were 28 cases in the MAS group,including 13 males(46.43%)and 15 females(53.57%),with an average age of(7.51±4.01)years. Compared with the control group,the MAS group were significantly more likely to have high fever( χ2=8.539, P=0.003),hepatomegaly( χ2=11.621, P<0.001),splenomegaly( χ2=11.710, P<0.001)and neurological involvement( χ2=27.619, P<0.001),with the differences being statistically significant. Meanwhile,there were statistically significant differences between the two groups in terms of white blood cell count( Z=-4.001, P<0.001),neutrophil count( Z=-3.659, P<0.001),platelet count( Z=-4.687, P<0.001),albumin level( Z=-4.018, P<0.001),alanine aminotransferase( Z=-3.846, P<0.001),aspartate aminotransferase( Z=-5.932, P<0.001),lactate dehydrogenase( Z=-6.150, P<0.001),triglycerides( Z=-5.874, P<0.001),fibrinogen( Z=-5.808, P<0.001),ferritin( Z=-5.280, P<0.001),erythrocyte sedimentation rate( Z=-3.971, P<0.001),ferritin/erythrocyte sedimentation rate( Z=-5.433, P<0.001),reduction of two-line cells in blood( χ2=11.408, P<0.001)and the presence of hemophagocytosis in bone marrow smears( χ2=28.260, P<0.001). Moreover,there was a statistically significant difference in MS scores between the two groups( Z=-6.148, P<0.001),with higher MS scores in the MAS group. Nevertheless,this study showed the median MS scores of both groups ≥-2.1. Conclusion:The MS score was significant to a certain degree as reference for the diagnosis of MAS,and this study showed that the MS score in the MAS group was significantly higher than the control group. However,the median MS scores in both groups were no less than -2.1. This might be related to the influence of factors during the assessment,which made it necessary to optimize the cutoff values of the MS score. Therefore,prospective studies should be carried out on the role of MS score in early identification of MAS.

Objective:To evaluate the clinical efficacy of Cai's gynecological nourishing kidney therapy for patients with diminished ovarian reserve (DOR).Methods:A randomly controlled trail was conducted. A total of 63 patients with DOR who were treated in the gynecology outpatient clinic of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine affiliated to Shanghai University of Traditional Chinese Medicine from September 2020 to January 2022 were set as observation subjects, and were divided into control group ( n=31) and observation group ( n=32) according to the random number table method. The patients in the control group were treated with Femoston, and the patients in the observation group were treated with Cai's gynecological nourishing kidney therapy on the basis of Femoston treatment. Both groups were treated for 3 menstrual cycles. Both antral follicle count (AFC) was performed by vaginal ultrasound, serum levels of TGF-β1, IL-1β, IL-2, IL-6 and IL-21 were detected by ELISA, and serum levels of FSH, LH, E2, anti-Müllerian hormone (AMH) and MDA were detected by biochemical methods. The TCM syndrome score was used to evaluate the severity of symptoms, and the menstrual score was used to evaluate the abnormal menstruation. Clinical efficacy was evaluated. Results:The total effective rate was 87.50% (28/32) in the observation group and 58.06% (18/31) in the control group, with statistical significance ( χ2=8.42, P=0.004). After treatment, the AFC in the observation group (3.93±2.32 vs. 2.21±2.18, t=3.03) was higher than that of the control group ( P<0.01). After treatment, the serum FSH level of the observation group [10.05 (8.35, 21.48) IU/L vs. 20.60 (8.00, 43.30) IU/L, Z=2.18] was lower than that of the control group ( P<0.05), and the level of AMH [0.19 (0.03, 0.47) μg/L vs. 0.02 (0.01, 0.24) μg/L, Z=-1.54] in the observation group was higher than that of the control group ( P<0.05). The serum levels of TGF-β1 [(68.27±11.76) ng/L vs. (55.33±13.03) ng/L, t=4.14] and IL-1β [(58.00±7.53) ng/L vs. (52.31±8.06) ng/L, t=2.89] in the observation group were higher than those in the control group, and the levels of IL-6 [(33.26±7.45) ng/L vs. (40.69±11.69) ng/L, t=3.02], the level of IL-21 [(118.37±15.56) ng/L vs. (140.43±25.51) ng/L, t=-4.04] was lower than that of the control group ( P<0.01). Conclusions:Cai's gynecological nourishing kidney therapy combined with Fenmaotong can effectively increase the AFC of DOR patients and improve clinical efficacy. Its mechanism of action may be related to reducing serum FSH and LH levels and increasing E2 levels.

Objective To investigate the relationship between the threonine and tyrosine kinase(TTK)gene and eyelid basal cell carcinoma(BCC).Methods Bioinformatics methods were used to screen the core gene(namely,TTK)associated with the occurrence and development of BCC from the Gene Expression Omnibus(GEO)database.Surgically removed eyelid BCC tissue specimens(BCC cells were divided into BBC Grade Ⅰ,Ⅱ and Ⅲ groups by tumor grade)and be-nign tumor tissue specimens(Control group)were collected from Ziyang Central Hospital for subsequent experiments.Cel-lular immunofluorescence assay(CIA)was used to detect the expression of the TTK gene in benign and malignant eyelid tumor cells.After knocking down TTK in BCC cells through transfection with lentiviruses(the cells transfected with LV-TTK-shRNA were taken as the TTK-shRNA group,and those transfected with LV-BBC-shRNA were taken as the BBC nega-tive control group),CIA was used to detect the expression of key proteins Bcl-2 and Bax in the apoptotic signaling pathway of each group of cells.Results The bioinformatics analysis showed that the TTK gene was the core gene associated with the occurrence and development of eyelid BCC.CIA detection results revealed that the fluorescence signal intensities in the tumor cytoplasm of Control,BCC Grade Ⅰ,Ⅱ,and Ⅲ groups were 1.03±0.07,1.28±0.11,1.58±0.13 and 1.92±0.17,respectively.The fluorescence signal intensity gradually increased,and the difference in fluorescence signal intensity among the four groups was statistically significant(all P<0.05).Compared with that in the Control group(1.02±0.05),the cell fluorescence intensity was increased in the BCC negative control group(1.74±0.12)and decreased in the TTK-shRNA group(1.31±0.09)(P<0.05).The difference in cell fluorescence intensity was significant among the Control,BCC nega-tive control and TTK-shRNA groups(all P<0.05).The fluorescence intensity of the anti-apoptotic protein Bcl-2 was 1.04±0.12 in the Control group,2.12±0.23 in the BCC negative control group,and 1.43±0.15 in the TTK-shRNA group.The fluorescence intensity of the pro-apoptotic protein Bax was 1.02±0.08 in the Control group,0.64±0.11 in the BCC negative control group,and 1.47±0.16 in the TTK-shRNA group.After TTK knockdown,the expression level of BcL-2 in BCC cells decreased,and that of Bax increased.The fluorescence intensities of BcL-2 and Bax were significantly different among the Control,BCC negative control and TTK-shRNA groups(all P<0.05).Conclusion The TTK gene plays a role in the regulation of eyelid BCC cell proliferation,and this effect is closely related to the PI3K-AKT-Bcl-2/Bax signaling path-way.
