Marsdenia tenacissima injection, a standard Marsdenia tenacissima extract (MTE), has been approved as an adjuvant therapeutic agent for various cancers. Our previous study showed that MTE inhibited the proliferation and metastasis of prostate cancer (PCa) cells. However, the underlying mechanisms and active ingredients of MTE against PCa were not completely understood. This study revealed that MTE induced significant decreases in cell viability and clonal growth in PCa cells. In addition, MTE induced the apoptosis of DU145 cells by reducing the mitochondrial membrane potential and increasing the expression of Cleaved Caspase 3/7, Cyt c, and Bax. In vivo, DU145 xenografted NOD-SCID mice treated with MTE showed significantly decreased tumor size. TUNEL staining and Western blot confirmed the pro-apoptotic effects of MTE. Network pharmacology analysis collected 196 ingredients of MTE linked to 655 potential targets, and 709 PCa-associated targets were retrieved, from which 149 overlapped targets were screened out. Pathway enrichment analysis showed that the HIF-1, PI3K-AKT, and ErbB signaling pathways were closely related to tumor apoptosis. Western blot results confirmed that MTE increased the expression of p-AKTSer473 and p-GSK3βSer9, and decreased the expression of p-STAT3Tyr705in vitro and in vivo. A total of 13 compounds in MTE were identified by HPLC-CAD-QTOF-MS/MS and UPLC-QTOF-MS/MS. Molecular docking analysis indicated that six compounds may interact with AKT, GSK3β, and STAT3. In conclusion, MTE induces the endogenous mitochondrial apoptosis of PCa by regulating the AKT/GSK3β/STAT3 signaling axis, resulting in inhibition of PCa growth in vitro and in vivo.

Objective:To investigate the relationship between cumulative fasting blood glucose(cumFPG)exposure and all-cause mortality.Methods:The prospective cohort study included 56 845 subjects of Kailuan Group who participated in physical examinations from 2006 to 2007, 2008 to 2009, and 2010 to 2011 with complete data and a median of 7.77 years of follow up. The end point event was all-cause mortality. The incidence of all-cause mortality was compared in various groups divided by four quartile of cumFPG. The Cox proportional hazards model and natural spline were used to analyze the effect of cumFPG on all-cause mortality.Results:During the average(7.77±1.05)years of follow-up, the incidence density of all-cause mortality was on the rise with the increase of cumFPG(4.93, 5.87, 8.48, and 14.02 per 1 000 person-years), with statistically significant difference by Log- rank test( P<0.001). Cox proportional hazards model showed that after adjusting for potential confounding factors(age, sex, body mass index, hypertension, baseline fasting plasma glucose), the HR value(95% CI)of all-cause mortality in the fourth quartile group was 1.28(1.15-1.42)compared to the first quartile. When cumFPG increased every standard deviation, the risk of all-cause mortality increased by 17%. Natural spline analysis exhibited a similar J curve relationship between cumFPG and all-cause mortality. Conclusion:High cumFPG is a risk factor of all-cause mortality.

Glycosidases are widely used in food and pharmaceutical industries due to its ability to hydrolyze the glycosidic bonds of various sugar-containing compounds including glycosides, oligosaccharides and polysaccharides to generate derivatives with important physiological and pharmacological activity. While glycosidases often need to be used under high temperature to improve reaction efficiency and reduce contamination, most glycosidases are mesophilic enzymes with low activity under industrial production conditions. It is therefore critical to improve the thermo-stability of glycosidases. This review summarizes the recent advances achieved in engineering the thermo-stability of glycosidases using strategies such as directed evolution, rational design and semi-rational design. We also compared the pros and cons of various techniques and discussed the future prospects in this area.

Objective:To investigate the clinical efficiency of gastrocnemius muscle flap combined with antibiotics loaded calcium sulfate in the treatment of postoperative infection and plate exposure of tibial plateau fracture in elderly patients.Methods:From January, 2015 to May, 2019, 21 elderly patients with postoperative infection and plate exposure of tibial plateau fracture were treated, including 14 males and 7 females with an average age of 72.6 years, ranging from 61 to 82 years. The average course of disease was 22.7 days, ranging from 6 to 91 days. The site of wound infection was at medial in 8 cases, lateral in 9 cases and bilateral in 4 cases. The size of wound ranged from 2.0 cm×3.5 cm to 5.0 cm×12.0 cm. All wounds were implanted with antibiotics loaded calcium sulfate and repaired by gastrocnemius muscle flap combined with skin graft after debridement. Muscle flap survival, wound healing, inflammatory index, fracture healing and knee joint function were recorded. The curative effect was evaluated by McKee infection treatment criteria and the knee joint function was evaluated by HSS scoring criteria.Results:All 21 muscle flaps survived. In 1 case, skin graft necrosis occurred in a small area, and the wound healed well after dressing change. One case had exudation which was clear and the bacterial culturing was negative, and the wound healed after 2 weeks of dressing change. The other incisions were healed in stage I, and the healing rate was 90%. All patients were followed-up for an average of 28.7(16-39) months. The redness and swelling occurred in 1 case without exudation after 2 months which disappeared after anti-infection treatment and didn't recur again. The infection recurred in 1 case after 5 months, and it which was controlled after debridement and plate removal. According to McKee criteria, 19 cases were cured, 1 improved and 1 recurred with an effective rate of 95.2%. The fracture healing time was from 3 to 7 months, with an average of 4.6 months. According to HSS scoring criteria, the knee joint function was excellent in 12 cases, good in 7 cases and moderate in 2 cases.Conclusion:After thorough debridement, gastrocnemius muscle flap combined with antibiotic loaded calcium sulfate can effectively control the infection, repair the wound, promote fracture union and restore limb function in the treatment of postoperative infection and plate exposure of tibial plateau fracture in elderly patients.
