Lipid turbidity disease is a metabolic disease featuring lipid metabolism disorders caused by many factors such as social environment， diet， and lifestyle， which is closely related to many diseases in modern medicine， such as hyperlipidemia， obesity， fatty liver， atherosclerosis， metabolic syndrome， and cardiovascular and cerebrovascular diseases， with a wide range of influence and far-reaching harm. According to the Huangdi Neijing， lipid turbidity disease reflects the pathological change of the body's physiologic grease. Grease is the thick part of body fluids， which has the function of nourishing， and it is the initial state and source of important substances in the human body such as brain， marrow， essence， and blood. Once the grease of the human body is abnormal， it can lead to lipid turbidity disease. The Huangdi Neijing also points out the physiological relationship between the transportation and transformation of body fluids and the rise and fall of the spleen and stomach， which can deduce the pathological relationship between the occurrence of lipid turbidity disease and the abnormal rise and fall of the spleen and stomach functions. Lipid turbidity disease is caused by overconsumption of fatty and sweet foods or insufficient spleen and stomach endowments， leading to disorders of the function of promoting clear and reducing turbidity in the spleen and stomach. This leads to the transformation of thick grease in body fluids into lipid turbidity， which accumulates in the body's meridians， blood vessels， skin pores， and organs， forming various forms of metabolic diseases. The research team believed that the pathological basis of lipid turbidity disease was the abnormal rise and fall of the spleen and stomach and the obstruction of the transfer of grease. According to the different locations where lipid turbidity stays， it was divided into four common pathogenesis types： ''inability to distinguish between the clear and turbid， turbid stagnation in the Ying blood''， ''spleen not rising clear， turbid accumulation in the vessels''， ''spleen dysfunction， lipid retention in the pores''， ''spleen failure to transportation and transformation， and grease accumulation in the liver''. According to the pathogenesis， it could be divided into four common syndromes， namely， turbid stagnation in the Ying blood， turbid accumulation in the vessels， lipid retention in the pores， and grease accumulation in the liver， and the corresponding prescriptions were given for syndrome differentiation and treatment， so as to guide clinical differentiation and treatment of the lipid turbidity disease.

AIM:To explore the efficacy and safe-ty of fecal microbiota transplantation combined with immune checkpoint inhibitors(ICIs)for malig-nant tumor patients with failed multi line anti-tu-mor treatment and concomitant cachexia,and to explore the changes in blood immunity and intesti-nal microbial environment in patients.METHODS:Five patients with malignant tumors who failed multi line anti-tumor treatment were enrolled and treated with ICIs combined with fecal microbiota transplantation.The efficacy was evaluated every 2-3 cycles,and adverse reactions were observed.Fe-cal 16srRNA gene sequencing and serum immuno-logical indicators were dynamically detected.RE-SULTS:Except for one patient who died 2.5 months after transplantation due to excessive tumor bur-den at enrollment,the overall survival of the re-maining four patients were extended(7.4,8.3,28.5,52.3 months).One patient with multiple intra-cranial metastases of lung adenocarcinoma signifi-cantly reduced the intracranial metastasis after in-testinal microbiota transplantation and almost dis-appeared.The serum IL-2,IL-10,TGF-β and other indicators of patients increased rapidly and then slowly decreased with the increase of transplanta-tion time,and finally were higher than before trans-plantation,with statistical differences.16srRNA gene sequencing analysis revealed significant differ-ences in the overall distribution of gut microbiota in patients after transplantation,gradually ap-proaching healthy transplant donors.All patients did not experience grade 2 or above adverse reac-tions,and the safety was good.CONCLUSION:For patients with malignant tumors,the combination of fecal microbiota transplantation and immuno-therapy may improve their quality of life,serum im-mune environment,and intestinal microbiota com-position,have a positive impact on survival progno-sis,and are safe and controllable,opening up new treatment methods for end-stage patients.

Non-small cell lung cancer(NSCLC)is one of the most common and deadly malignant tumors worldwide,with surgical resection being the primary treatment for early-stage NSCLC.Tumor spread through air spaces(STAS)is a novel pattern of tumor dissemination into the air spaces in the lung.Its occurrence after sublobar resection is closely associated with recurrence and distant metastasis,making its con-sideration a vital factor in surgical strategy selection and prognostic evaluation.Patients with STAS-positive status exhibit significantly higher postoperative recurrence rates than do STAS-negative patients,with molecular mechanisms involving tumor microenvironment remodeling,specific genetic mutations,and epithelial-mesenchymal transition(EMT).Imaging techniques including computed tomography(CT)and positron emission tomography/CT have shown potential for preoperative STAS prediction,although their accuracy and practicality require improvement.This paper reviews the definition,pathological characteristics,and related mechanisms of STAS,with a focus on surgical ap-proach selection for STAS-positive patients and its role in cancer recurrence after sublobar resection of early-stage NSCLC.Future research directions include optimization of preoperative diagnostic methods for STAS,exploration of molecular targeted therapies,and development of imaging-based precision prediction models.

BACKGROUND:Skeletal muscle insulin resistance is the key pathological link of type 2 diabetes.The traditional Chinese medicine compound Roujishuncuiyin can effectively improve skeletal muscle insulin resistance,but its mechanism has not been clarified.OBJECTIVE:To explore the mechanism of Roujishuncuiyin on skeletal muscle insulin resistance in type 2 diabetes mice.METHODS:Forty db/db mice with type 2 diabetes mellitus were randomized into a model group,a low-dose Roujishuncuiyin group,a high-dose Roujishuncuiyin group,and a positive drug group,with 10 mice in each group.The latter three administration groups were given 157.5 mg/g and 630 mg/g Roujishuncuiyin and 200 mg/g metformin hydrochloride aqueous solution by gavage once a day,respectively.In addition,10 db/dm mice were selected as the blank control group.Mice in the model and blank control groups were given the same dose of 0.9％NaCl solution by gavage.After 12 weeks of intervention,fasting blood glucose was measured in each group of mice,and oral glucose tolerance test was performed to calculate the area under the blood glucose curve.ELISA was used to detect serum insulin level and calculate the resistance index.Mitochondrial structure of skeletal muscle tissue was observed under transmission electron microscopy.Western blot was used to detect the expression levels and phosphorylation levels of protein kinase B(AKT)and glycogen synthase kinase 3β(GSK-3β)proteins in skeletal muscle.RESULTS AND CONCLUSION:(1)Compared with the blank control group,fasting blood glucose,fasting insulin and insulin resistance index were significantly higher in the model group(P＜0.05),the area under the curve of the oral glucose tolerance test was significantly increased(P＜0.05),the expression of p-AKT and p-GSK3β proteins in tibialis anterior muscle was significantly decreased(P＜0.05),and there was a large amount of mitochondrial damage in tibialis anterior muscle and a large number of lipid droplets in the interstitium.(2)Compared with the model group,fasting blood glucose,fasting insulin,and insulin resistance index were significantly reduced in the low-and high-dose Roujishuncuiyin groups and the positive control group(P＜0.05),the area under the curve of the oral glucose tolerance test was reduced(P＜0.05),the expression of p-AKT and p-GSK3β proteins in the tibialis anterior muscle was significantly elevated(P＜0.05),and mitochondrial damage in the tibialis anterior muscle was significantly ameliorated,with decreased lipid droplets in the interstitium.(3)The above indexes were better in the high-dose Roujishuncuiyin group than the low-dose Roujishuncuiyin group(P＜0.05),while there was no significant difference between the high-dose Roujishuncuiyin group and positive control group(P＞0.05).To conclude,by upregulating the protein levels of p-AKT and p-GSK3β in skeletal muscle tissue,the traditional Chinese medicine compound Roujishuncuiyin can improve structural disorders and mitochondrial morphology in skeletal muscle tissue,reduce insulin resistance in the skeletal muscle and regulate glucose homeostasis in the body.

Objective:To compare the efficacy and safety of a domestic hair follicle extraction system versus traditional follicular unit excision (FUE) in extracting hair follicles for the treatment of androgenetic alopecia (AGA) .Methods:A multicenter, randomized, self-controlled clinical trial was conducted on AGA patients aged 18 - 59 years who were recruited from the Huashan Hospital, Fudan University, the Affiliated Hangzhou First People's Hospital, and the China-Japan Friendship Hospital between June 2023 and September 2024. Each patient's scalp was randomly divided into two sides (experimental side vs. control side) using an envelope method. The experimental side underwent robotic hair transplantation with a domestic hair follicle extraction system, and the control side underwent traditional FUE. Hair follicles were extracted from the safe donor area in the occipital region, and implanted into the ipsilateral hair loss area. The primary outcome was the hair transection rate which was calculated immediately after follicular extraction. The secondary outcomes included the hair follicle unit loss rate and the change in hair density at the recipient site on postoperative day 14. Safety was evaluated by assessing the incidence of folliculitis at the donor site on postoperative day 14 and the overall incidence of adverse events. Surgical outcomes were evaluated at 9 months after surgery. Comparisons of evaluation indicators among groups were performed by using a paired t test or Wilcoxon signed-rank test. Results:A total of 55 patients with AGA (51 males and 4 females, aged 32.71 ± 5.75 years) completed the hair follicle transplantation and postoperative follow-up. The hair transection rate ( M[ Q1, Q3]) was 6.65% (4.56%, 10.16%) in the experimental group and 5.28% (3.04%, 8.89%) in the control group (difference = 1.24%, 95% CI: -0.24%, 2.65%) . The hair follicle unit loss rate was 2.00% (1.00%, 3.50%) in the experimental group and 0.50% (0, 2.00%) in the control group, with a significant difference between the two groups ( P = 0.008) . On postoperative day 14, there was no significant difference in the hair density between the experimental group and control group (72.20 ± 25.95 per cm 2vs. 76.49 ± 30.84 per cm 2, P = 0.173) . At 9-month follow-up, both groups showed improvement in the investigator's overall score in the recipient areas. Seven adverse events occurred in 7 subjects (12.72%) in each group, and all were mild folliculitis. Conclusion:The domestic hair follicle extraction system demonstrated comparable efficacy and safety to the traditional FUE in hair transplantation.

Objective To elucidate the mechanism through which Gypenoside L inhibits the growth of colon cancer by modulating carnitine palmitoyltransferase 1B (CPT1B),a pivotal enzyme in the fatty acid metabolism pathway. Methods Through in vitro experiments,various concentrations of Gypenoside LI LI were applied to inter-vene in colon cancer RKO and SW620 cells. The effects of Gypenoside LI on these cells were comprehensively evalu-ated using the CCK-8 assay,wound healing assay,colony formation assay,and live-dead cell staining,focusing on its impact on cell proliferation,migration,and apoptosis. Additionally,a human colon cancer tissue microarray (TMA) was utilized in conjunction with multiplex fluorescence immunohistochemistry to analyze the expression of CPT1B in colon cancer and adjacent tissues. SW620 cells were transfected with siRNA,and the mRNA and protein expression levels of CPT1B post-transfection were assessed using quantitative real-time PCR (qPCR) and Western blotting. Furthermore,an in vivo nude mouse colon cancer model was established to investigate the inhibitory effect of Gypenoside LI LI on colon cancer growth. Results In vitro experiments demonstrated that Gypenoside LI LI effectively inhibited the proliferation and migration of RKO and SW620 cells in a concentration-and time-dependent manner. Additionally,multiple fluorescence immunohistochemistry analyses revealed that the expression level of CPT1B in colon cancer tissues was significantly higher than that in adjacent non-tumor tissues. Gypenoside LI LI promoted ROS accumulation by inhibiting CPT1B expression. In vivo experiments further confirmed that Gypenoside LI LI could inhibit tumor formation in nude mice and reduce CPT1B expression. Conclusions This study elucidates the mechanism by which Gypenoside LI inhibits the growth of colon cancer cells. Specifically,it downregulates CPT1B,leading to increased accumulation of reactive oxygen species (ROS),disruption of fatty acid oxidation metabolism,and ultimately inducing apoptosis in colon cancer cells. These findings offer valuable insights into colon cancer treatment,suggesting new therapeutic strategies and potential drug targets.
