Objective: To investigate the mechanism of Yishen Tongluo Formula in ameliorating renal pyroptosis in diabetic nephropathy mice by regulating the toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-κB (NF-κB) signaling pathway. Methods: Sixty C57BL/6 male mice were randomly divided into control (10 mice) and intervention groups (50 mice) using random number table method. The diabetes nephropathy model was established by intraperitoneally injecting streptozotocin(50 mg/kg). After modeling, the intervention group was further divided into model, semaglutide (40 μg/kg), and high-, medium-, and low-dose Yishen Tongluo Formula groups (15.6, 7.8, and 3.9 g/kg, respectively) using random number table method. The high-, medium-, and low-dose Yishen Tongluo Formula groups were administered corresponding doses of medication by gavage, the semaglutide group received a subcutaneous injection of semaglutide injection, and the control group and model groups were administered distilled water by gavage for 12 consecutive weeks. Random blood glucose levels of mice in each group were monitored, and the 24-h urinary protein content was measured using biochemical method every 4 weeks; after treatment, the serum creatinine and urea nitrogen levels were measured using biochemical method. The weight of the kidneys was measured, and the renal index was calculated. Hematoxylin and eosin, periodic acid-Schiff, periodic Schiff-methenamine, and Masson staining were used to observe the pathological changes in renal tissue. An enzyme-linked immunosorbent assay was used to detect urinary β2-microglobulin (β2-MG), neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule-1 (KIM-1) levels. Western blotting and real-time fluorescence PCR were used to detect the relative protein and mRNA expression levels of nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3), Caspase-1, gasdermin D (GSDMD), interleukin-1β (IL-1β), and interleukin-18 (IL-18) in renal tissue. Immunohistochemistry was used to detect the proportion of protein staining area of the TLR4, MyD88, and NF-κB in renal tissue. Results: Compared with the control group, the random blood glucose, 24-h urinary protein, serum creatinine, urea nitrogen, and renal index of the model group increased, and the urine β2-MG, NGAL, and KIM-1 levels increased. The relative protein and mRNA expression levels of NLRP3, Caspase-1, GSDMD, IL-1β, and IL-18 in renal tissue increased, and the proportion of TLR4, MyD88, and NF-κB protein positive staining areas increased (P<0.05). Pathological changes such as glomerular hypertrophy were observed in the renal tissue of the model group. Compared with the model group, the Yishen Tongluo Formula high-dose group showed a decrease in random blood glucose after 12 weeks of treatment (P<0.05). The Yishen Tongluo Formula high- and medium-dose groups showed a decrease in 24-h urinary protein, creatinine, urea nitrogen, and renal index, as well as decreased β2-MG, NGAL, and KIM-1 levels. NLRP3, Caspase-1, GSDMD, IL-1 β, and IL-18 relative protein and mRNA expression levels were also reduced, and the proportion of TLR4, MyD88, and NF-κB protein positive staining areas was reduced (P<0.05). Pathological damage to renal tissue was ameliorated. Conclusion Yishen Tongluo Formula may exert protective renal effects by inhibiting renal pyroptosis and alleviating tubular interstitial injury in diabetic nephropathy mice by regulating the TLR4/MyD88/NF-κB signaling pathway.

Objective To investigate the role of long non-coding RNA-small nucleolar RNA host gene 3(lncRNA-Snhg3)and its regulatory mechanism in the hepatic glucose metabolism of mice.Methods Adenovirus Snhg3 was over-expressed by the tail vein injection in db/db mice,and then glucose tolerance and pyruvate tolerance were meas-ured.The mRNA expression of mouse liver gluconeogenesis-related genes phosphoenolpyruvate carboxylase(Pepck)and glucose-6-phosphatase(G6pc)and stress-inducing protein 2(Sestrin2,Sesn2,a gene adjacent to Snhg3)were de-tected by RT-qPCR.The dual luciferase reporter assay was used to detect the effect of Snhg3 on the Sesn2 promoter activity in 293T cells.Results Snhg3 over-expression improved glucose tolerance and pyruvate tolerance in db/db mice.Snhg3 over-expression inhibited the mRNA of gluconeogenesis genes of Pepck(P＜0.05)and G6pc(P＜0.05),while promoted the mRNA of Sesn2(P＜0.01).Meanwhile,Snhg3 over-expression promoted Sesn2 promoter activity in 293T cells(P＜0.05).Conclusions Snhg3 improves glucose metabolism in mice by promoting Sestrin2 expression.

Objective To investigate the role and regulatory mechanism of stress-inducing protein 1(SESN1)in liver gluconeogenesis of fasting mice.Methods RT-qPCR was used to detect mRNA expression of SESN1 in liver tissues of C57BL/6J mice and primary mouse hepatocytes treated with forskolin(Fsk)and dexamethasone(Dex).HepG2 cells were transfected with plasmids and the effects of SESN1 overexpression on mRNA expression of gluconeogenesis related genes PGC-1α,PEPCK and G6Pase was detected by RT-qPCR.The effect of SESN1 on the promoter activity of PGC-1α in HepG2 cells was studied using a dual luciferase reporter system.The effect of SESN1 on PGC-1α deacetylation was detected by overexpression of SESN1 and inhibition of SIRT1 expression.By knocking down SIRT1 expression,we detected whether it mediated the changes in mRNA levels of SESN1 in-duced gluconeogenesis related genes.Results The mRNA expression of SESN1 was significantly increased in liver tissues of starved C57BL/6J mice and in primary hepatocytes treated with Fsk and Dex(P<0.001).Over-expression of SESN1 in HepG2 cells promoted mRNA expression of PGC-1α,PEPCK and G6Pase(P<0.001)and promoter activity of PGC-1α(P<0.001).Over-expression of SESN1 decreased the acetylation level of PGC-1α in primary hepatocytes.Sirt family inhibitors NAM and shRNA adenovirus interfered with SIRT1 expression respective-ly,and antagonized the deacetylation effect of SESN1 on PGC-1α.The expression of PGC-1α,PEPCK and G6Pase induced by SIRT1 was also significantly impaired(P<0.000 1).Conclusions SESN1 regulates liver gluconeogene-sis in mice with a SIRT1-dependent mechanism.

Objective To investigate independent risk factors for unintended initial dissection of the posterior plane(UIDPP)during small incision lenticule extraction(SMILE)by surgeons with different qualifications.Methods A total of 1 600 patients(3 003 eyes)who underwent SMILE performed by three surgeons with different qualifications from April to September 2021 were selected as the research subjects,including 911 males and 689 females,with an average age of(21.82±3.55)years.The incidence of UIDPP in patients was recorded,along with a comprehensive summary of the age,gender,eyes,surgeons,surgical proficiency,subjective refraction,central corneal thickness,lenticule thickness,side cut angle,and peripheral lenticule thickness of the patients.Independent risk factors of UIDPP were analyzed using the binary logistic regression.Test level:α=0.05.Results In this study,the incidence of UIDPP was 6.56％(197/3 003),and the lenticule was successfully removed in all eyes.Multivariate logistic regression analysis demonstrated that surgeon(P=0.035),surgical proficiency(P=0.026),eyes(P=0.007),lenticule thickness(P＜0.001),and peripheral lenticule thick-ness(P＜0.001)were independent risk factors associated with the UIDPP during SMILE surgery.No significant differences were observed in other parameters(all P＞0.05).Conclusion Surgeons,surgical proficiency,eyes,lenticule thick-ness,and peripheral lenticule thickness are independent risk factors of UIDPP.

[Abstract] Objective: To evaluate the expression level of FOXD1 in glioma tissues of different grades, and to investigate the correlation between the expression of FOXD1 and the prognosis of glioma patients. Methods: The tumor tissues were collected from 40 glioma patients, who received surgical treatment in the neurosurgery department of the First Hospital of China Medical University from September 2014 to February 2015; Seven non-tumor tissues obtained from patients underwent internal decompression for traumatic brain injury were used as controls. The FOXD1 expression in glioma and non-tumor brain tissues was analyzed by qRT-PCR and IHC, and the correlations between clinical pathological features of glioma patients and FOXD1 expression level were analyzed. Furthermore, the Kaplan-Meier method was used to analyze the relationship between FOXD1 expression and survival time of patients. In addition, the expression of FOXD1 in glioma tissues and its relationship with patients’prognosis were confirmed by the data from GEO (GSE4290, GSE2223) and Rembrandt database. Results: qRT-PCR showed that the FOXD1 mRNA expression in glioma tissues of WHO grade IV was significantly higher than that of non-tumor brain tissues and glioma tissues of WHO grade II (P<0.01). German immunohistochemical score (GIS) was used to evaluate the immunohistochemical staining intensity, and the relationship between FOXD1 expression and clinical pathological features was analyzed. The results showed that FOXD1 in glioma tissues was related to WHO phathological grade level (χ2=11.73， P<0.01). There was statistically significant difference between the survival time of FOXD1 high expression group and FOXD1 low expression group (P=0.043). The data from GEO data base (GSE4290, GSE2223) and Rembrandt datasets showed that glioma tissues have a higher FOXD1 mRNA expression level than normal brain tissues, and the elevated expression of FOXD1 mRNA was negatively associated with the survival time of glioma patients. Conclusion: FOXD1 was highly expressed in glioma tissues, and the expression level of FOXD1 was increased as the pathological grade increases. The elevated expression of FOXD1 was related with the poor survival of glioma patients.
