BACKGROUND:Abnormal extracellular matrix accumulation and excessive proliferation of fibroblasts are the main manifestations of pathological scars.Excessive proliferation of fibroblasts leads to the production of large amounts of collagen-based extracellular matrix.Therefore,to investigate the role of fibroblast fibrosis in the formation of pathological scar will provide a new idea for revealing the mechanism of pathological scar and biological therapy. OBJECTIVE:To investigate the effect of RAS-selective lethal small molecule 3(RSL3)on the fibrosis of human pathological scar fibroblasts. METHODS:Then cases of pathological scar tissue and normal skin tissue samples from the same individuals,provided by the Department of Burn Plastic Surgery,General Hospital of Ningxia Medical University,were collected.Fibroblasts of human pathological scar and human normal skin were extracted and used in the following experiments.The general condition of the pathological scar tissue and the normal skin tissue was detected by hematoxylin-eosin staining.The appearance of fibroblasts from pathological scar and normal skin were observed by inverted microscope.The fibroblasts were verified by immunofluorescence assay.The cells were treated with different concentrations of RSL3(1,3,5,7,9,11,13 μmol/L).The inhibitory concentration of RSL3 on fibroblasts was detected by cell counting kit-8.Control group(without treatment)and RSL3 intervention group(treated with 7 μmol/L RSL3 for 24 hours)were set up.The mRNA and protein expressions of glutathione peroxidase 4,type Ⅰ collagen,type Ⅲ collagen and α-smooth muscle actin were detected by Qrt-PCR and western blot,respectively.Level of malondialdehyde in cells was detected.The residual scratch area was measured by cell scratch test after 24 hours to calculate the percentage of residual scratch area. RESULTS AND CONCLUSION:The expression of glutathione peroxidase 4 in the pathological scar group was higher than that in the normal skin group(Mrna:t=3.252,P<0.01;protein:t=5.075,P<0.01).The expression of glutathione peroxidase 4 in the pathological scar fibroblast group was higher than that in the normal skin fibroblast group(Mrna:t=10.32,P<0.01;protein:t=26.22,P<0.01).Compared with the control group,the expression of glutathione peroxidase 4 was decreased(Mrna:t=2.798,P<0.05;protein:t=4.643,P<0.01),the content of malondialdehyde was increased(t=2.917,P<0.05),the expression of type Ⅰ collagen(Mrna:t=15.84,P<0.01;protein:t=4.610,P<0.01),type Ⅲ collagen(Mrna:t=28.86,P<0.01;protein:t=7.713,P<0.01)and α-smooth muscle actin(Mrna:t=2.671,P<0.05;protein:t=7.417,P<0.01)were decreased in the RSL3 intervention group.Compared with the control group,the migration ability was weakened in the RSL3 intervention group(t=14.06,P<0.01).To conclude,RSL3 can inhibit the expression of glutathione peroxidase 4 and then inhibit the ability of fibrosis and migration of pathological scar fibroblasts.

Eclipta prostrata L.has been used in traditional medicine and known for its liver-protective properties for centuries.Wedelolactone(WEL)and demethylwedelolactone(DWEL)are the major coumarins found in E.prostrata L.However,the comprehensive characterization of these two compounds on non-alcoholic fatty liver disease(NAFLD)still remains to be explored.Utilizing a well-established zebrafish model of thioacetamide(TAA)-induced liver injury,the present study sought to investigate the impacts and mechanisms of WEL and DWEL on NAFLD through integrative spatial metabolomics with liver-specific transcriptomics analysis.Our results showed that WEL and DWEL significantly improved liver function and reduced the accumulation of fat in the liver.The biodistributions and metabolism of these two compounds in whole-body zebrafish were successfully mapped,and the discriminatory endogenous metabolites reversely regulated by WEL and DWEL treatments were also characterized.Based on spatial metabolomics and transcriptomics,we identified that steroid biosynthesis and fatty acid metabolism are mainly involved in the hepatoprotective effects of WEL instead of DWEL.Our study unveils the distinct mechanism of WEL and DWEL in ameliorating NAFLD,and presents a"multi-omics"platform of spatial metabolomics and liver-specific transcriptomics to develop highly effective compounds for further improved therapy.

Zuoguiwan， one of the classic formulas of traditional Chinese medicine （TCM）， has the effects of nourishing genuine Yin， supplementing essence， and replenishing marrow， and it is widely used in the clinical treatment of diseases caused by congenital essence deficiency. This article systematically reviewed the ancient books involving congenital deficiency and the modern research reports on the treatment of congenital deficiency with Zuoguiwan. From the formulation principle of Zuoguiwan and the TCM concept of congenital deficiency， this article discussed the theoretical basis of treating congenital deficiency with Zuoguiwan based on the modern research results. Ancient physicians have discovered that the deficiency of parents can lead to abnormal physical development and weakness of the offspring. ZHANG Jingyue divided congenital essence Qi into genuine Yin and primordial Yang and formulated Zuoguiwan based on the principle of Yin-Yang mutual assistance for supplementing congenital genuine Yin. Experimental studies have shown that Zuoguiwan can up-regulate the expression of connexin 43 （Cx43） protein and improve gap junction intercellular communication （GJIC） function to promote osteogenic differentiation and maturation of bone marrow mesenchymal stem cells and ameliorate abnormal bone development caused by congenital essence deficiency. Zuoguiwan can enhance the expression and activity of Reelin to ameliorate abnormal brain development. It can upregulate the expression of Cx43 protein to intervene in the phosphatidylinositol 3 kinase/protein kinase B （PI3K/Akt） pathway， thus repairing the reproductive functions. Zuiguiwan can promote the development and maturation of T cells and activate the Wnt/β-catenin signaling pathway in the thymus to improve immune functions. In addition， it can promote the expression of β-catenin and inhibit the expression of microtubule-associated proteins 1 light chain 3 （LC3） to attenuate skin dysfunctions. Moreover， Zuoguiwan can guide the differentiation of stem cells via the correlation between essence and vitality in TCM. Zuoguiwan has demonstrated significant therapeutic effects on some diseases in the pediatric， andrological， gynecological， geriatric， internal medicine， orthopedic and skin disease departments. On the basis of the results of experiments and clinical applications， this paper analyzes the specific connotation of congenital deficiency proposes that congenital deficiency should be subdivided into the four aspects of essence， Qi， Yin， and Yang. Congenital essence deficiency as the deficiency of genuine Yin can lead to deficiency of kidney essence in the offspring and dysfunction of kidney storing essence. Pharmacological studies have discovered that Cuscutae Semen， Lycii Fructus， and Achyranthis Bidentatae Radix in Zuoguiwan contain active components such as quercetin and kaempferol， which act on the targets such as recombinant prostaglandin endoperoxide synthase 2 （PTGS2）， interleukin-6 （IL-6）， mitogen-activated protein kinases （MAPK14）， tumor necrosis factor （TNF）， TP53， Vascular permeability factor A （VEGFA）， and albumin （ALB） to play a role in reproductive system development and hormone responses. Zuoguiwan has unique advantages over Liuwei Dihuangwan in nourishing congenital genuine Yin in the kidney and can achieve better therapeutic effects on the syndromes and diseases caused by congenital essence deficiency. This review is expected to enrich the knowledge about the efficacy and clinical application of Zuoguiwan， provide new perspectives and methods for the prevention and treatment of congenital deficiency and congenital essence deficiency， and give insights into the application of Zuoguiwan in modern healthcare， especially in the nurturing of offspring.

Objective:To investigate the risk factors affecting the occurrence of perioperative complications in patients with locally progressive gastric cancer undergoing radical gastric cancer treatment.Methods:The clinical data of 129 patients with locally progressive gastric cancer from January 2017 to December 2019 in Shaanxi Provincial People′s Hospital were retrospectively analyzed, including 98 males and 31 females, with an age ranged from 27 to 79 years and a mean age of (60.61±10.00) years. The postoperative complications of 129 patients with gastric cancer were firstly counted, and then the relationship between clinical data such as patients′ general condition, intraoperative status and pathological indexes and the occurrence of perioperative complications was analyzed by using univariate analysis, and significant factors were included in the logistic regression model for multifactor analysis to study the independent risk factors for the occurrence of perioperative complications.Results:Of the 129 patients, 25 cases (19.38%) had postoperative complications, including 10 cases (7.75%) with Clavien-Dindo classification combined with grade Ⅲ or higher complications. The results of univariate analysis suggested ACCI score >4 (30.76% vs 68.00%, χ2=11.86, P=0.001), body mass index ≥25 kg/m 2 (24.03% vs 60.00%, χ2=12.18, P=0.001), and preoperative hypoproteinemia (17.30% vs 36.00%, χ2=4.25, P=0.039), vascular cancer embolism (14.42% vs 40.00%, χ2=7.70, P=0.006), operative time ≥ 400 min (26.92% vs 52.00%, χ2=5.84, P=0.016), intraoperative bleeding ≥ 400 mL (13.46% vs 44.00%, χ2=12.03, P=0.001) were risk factors for the development of perioperative complications in patients with locally progressive gastric cancer. Multifactorial analysis showed that ACCI score >4, body mass index ≥25 kg/m 2, preoperative hypoproteinemia, vascular cancer embolism, and intraoperative bleeding ≥400 mL were independent risk factors for the occurrence of perioperative complications in patients with locally progressive gastric cancer ( P<0.05). Conclusions:The occurrence of perioperative complications in locally progressive gastric cancer hands was closely associated with ACCI score, body mass index, preoperative hypoproteinemia, vascular cancer embolism and intraoperative bleeding. ACCI score is expected to be a predictor of the occurrence of perioperative complications in patients with locally progressive gastric cancer.
