OBJECTIVE: To investigate the effects of three compounds extracted from Tripterygium wilfordii Hook (TW) on angiogenesis in the chick chorioallantoic membrane (CAM). METHODS: Fifty fresh Hongkong Mahua chicken eggs were divided into five groups: PBS-treated group, TW1-, TW2- and TW3-treated groups and Rg3-treated group. After disinfection, the eggs were incubated for six days in a constant temperature box with the temperature being controlled within 37.8 degrees C, then exposed CAM, laid the filter papers with specimen on the CAM, and the eggs were incubated for another two days. CAM was fixed with the mixture of methyl alcohol and acetone at room temperature for about 15 min, and then cutting the CAM, taking photos and observing the angiogenesis in the CAM. RESULTS: There were many CAM vessels in the PBS-treated group and the blood vessel net could be seen clearly. The number of CAM vessels in the TW1-, TW2- and TW3-treated groups (10 microg/egg) was much less than that in the PBS-treated group. Furthermore, the frame of the vessels was not clear, and the color was obscure. Inhibition rates of angiogenesis in the TW1-, TW2- and TW3-treated groups were 80%, 60% and 100% respectively, while the inhibition rate of angiogenesis in the Rg3-treated group (10 microg/egg) was only 10%. CONCLUSION: TW1, TW2 and TW3 can obviously restrain the angiogenesis in CAM and still need further study.

Objective:To explore a better measurement mode of shear wave elastography (SWE) in the skin of lymphedema limbs, and to test its diagnostic efficacy in lymphedema.Methods:Between 1st and 10th August, 2023, 22 healthy volunteers were recruited in the Department of Medical Ultrasonics, Institute of Diagnostic and Interventional Ulrasound, the First Afiliaed Hospital of Sun Yat-Sen University to measure the Young's modulus (E-value) of limb skin by SWE using a gel pad (GP group) and the thick-layer coupling gel (CG group) respectively. Then between 15th August and 28th September, 2023, 11 patients with 13 lower limb lymphedema, who were treated in the Department of Microsurgery, Orhopaedic Trauma and Hand Surgery, the First Affiliaed Hospital of Sun Yat-Sen University, were consecutively enrolled to find out the E-value of skin in oedematous limbs. The receiver operating characteristic curve (ROC) was constructed and the sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated to evaluate the diagnostic efficiency. SPSS 26.0, R studio and GraphPad Prism 8 software were used for statistical analysis. Paired sample non-parametric test (Wilcoxon signed rank test) was used to compare the difference in E-value between the 2 groups. P<0.01 was considered statistically significant. Spearman correlation test was used to analyse the correlation of E-value values between the GP group and CG group. Results:Overall, it was found from the healthy volunteers that E-value of skin in distal limbs were higher than that in proximal limbs, especially in lower extremities. E-value of all scanned location in GP group were found higher than those of CG group with statistically significant difference ( P<0.01), and the values of interclass correlation coefficient (ICC) showed a good repeatability. The 11 patients with lymphedema in 13 lower extremities were examined with the thick-layer coupling gel. The skin E-value in calf of patients with lymphedema were significantly higher than that of the healthy volunteers ( P<0.01), except the skin of thighs ( P>0.01). A lymphedema was diagnosed while either a skin E-value was 27.6 kPa calculated by Youden index or with the thickness of skin was 2.3 mm. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy in the diagnosis of a lymphedema were found at 92.3%, 100%, 100%, 95.7% and 97.1%, respectively. The area under curve (AUC) of ROC was 0.962. The correlation coefficients (R) of E-value in arm, forearm, thigh and lower leg in the GP group and CP group were 0.665, 0.882, 0.850 and 0.815, respectively, which were all significantly correlated. Conclusion:Application of thick layer coupler in ultrasound skin SWE is highly feasible, and the combination of ultrasound skin SWE and skin thickness has higher diagnostic efficiency in the diagnosis of lower extremities lymphedema. It allows more accurate ultrasonic image technical support for early monitoring and diagnosis of lymphedema, microsurgical treatment and a quantitatively perioperative evaluation.

Objective:To investigate the effect of tofacitinib on early atherosclerosis of patients with systemic lupus erythematosus and explore the possible relationship between lupus nephritis and early atherosclerosis of systemic lupus erythematosus.Methods:Sixteen 8-week-old female MRL/lpr mice with a body weight of 20~25 g were selected and randomly divided into the treatment group and placebo group, with 8 mice in each group. The treatment group diluted tofacitinib by normal saline, and given at a dose of 10 mg·kg -1·d -1, and the placebo group (starch tablets) administered the medication in the same way as the treatment group for a total of 8 weeks. The ELISA method was applied to detect serum anti-dsDNA antibody levels in the two groups of mice. Bradford method protein concentration was used to determine the level of urine protein in mice. Automatic biochemical analyzer was used to detect blood lipids, urea nitrogen, serum creatinine, complement C3, complement C4 levels. Western blotting was used to determine the protein expression levels of monocyte chemoattractant protein-1 (MCP-1), non-receptor protein tyrosine kinase family 1 (JAK1), signal transducer and activator of transcription 1 (STAT1) and signal transducer and activator of transcription 2 (STAT2) in aortic and kidney tissues. After the aortic arch section were prepared, oil red O was used to stain the sections, and the vascular plaque area and intimal thickness were evaluated by ImageJ software. The kidneys were dissected and stained with HE, and the active lesions of lupus nephritis were evaluated using the glomerular activity scoring system. SPSS 23.0 software was used for statistical analysis, in which the between-group comparison was performed using two independent samples t-test, and the correlation analysis was performed using the Spearman method.
