ABSTRACT

The antioxidant effects of the triterpenoid-rich extracts from Euryale ferox shell [ES] have been confirmed in vitro. This study examined whether the triterpenoid-rich extract from ES eases human hyperglycemia and diabetes caused by metabolic disorders. Normal and streptozocin [STZ]-induced diabetic mice were used as controls for the four groups that received the triterpenoid-rich extracts of ES suspended in distilled water orally at doses of 200, 300, 400, 500 +/- 2 mg/L. Body weight, blood glucose and pancreatic tissue morphology were observed after 4 weeks. The expression of protein tyrosine phosphatase-1B [PTP1B] and insulin receptor substrate [IRS-1] proteins, which are related to the regulation of glucose metabolism in vivo, were also investigated. Compared with the model group [LD[50] 900 +/- 2 mg/L], it was found that the triterpenoid-rich extracts of ES could regulate glucose metabolism [P<0.01] and cause body weight to return to normal levels [P<0.05]. Islet morphology recovered well, the expression of the negative regulation protein PTP1B gene was reduced and insulin receptor IRS-1 protein expression was increased. These data prove that the triterpenoid-rich extracts from ES have a therapeutic effect on diabetes by insulin resistance

ABSTRACT

Mannosylerythritol lipids (MELs), mainly produced by Ustilago and Pseudozyma, are surface active compounds that belong to the glycolipid class of biosurfactants. MELs have potential application in food, pharmaceutical and cosmetics industries due to their excellent surface activities and other peculiar bioactivities. In recent years, the research field of MELs has regained much attention abroad. However, MELs are rarely studied in China. In this review, the producing microorganisms and production conditions, diverse structures, biochemical properties, structure-function relationship and biosynthetic pathways of MELs are described. Some research problems and prospects are summarized and discussed as well.

ABSTRACT

Interferon beta (IFN-beta) and TNF-related apoptosis-inducing ligand (TRAIL) are effective anticancer agents. Adeno-associated virus (AAV) is one of the current most promising gene delivery vectors. Previously, we constructed tumor-targeting AAV-hTERT-IFN-beta and AAV-hTERT-TRAIL by inserting IFN-beta or TRAIL gene into AAV controlled by hTERT promoter. The studies showed that either single IFN-beta or TRAIL gene therapy exhibited a certain extent anticancer effect. Here, we report their inhibitory effects on A549 lung cancer cell growth in vitro and in vivo by combined AAV-hTERT-IFN-beta and AAV-hTERT-TRAIL. Expression of secreted IFN-beta in lung cancer A549 cells infected by AAV-hTERT-IFN-beta was detected by enzyme-linked immunosorbent assay (ELISA). The growth-suppressing effect of AAV-hTERT-IFN-beta in combination with AAV-hTERT-TRAIL on several cancer cell lines was assessed by MTT assay. Apoptosis of A549 cancer cells infected by AAV-hTERT-IFN-beta alone, AAV-hTERT-TRAIL alone, and their combination was evaluated by apoptotic cell staining and flow cytometry (FCM), respectively. The antitumor effect of the combination of AAV-hTERT-IFN-beta with AAV-hTERT-TRAIL in vivo was further evaluated through A549 lung cancer xenograft in nude mice. The results showed that the combinational treatment was superior to any alone and presented intensified tumor cytotoxic and apoptotic effect on A549 cancer cells. Most importantly, the combination of AAV-hTERT-IFN-beta with AAV-hTERT-TRAIL exhibited significant antitumor effect and eliminated all tumor masses in nude mice, which lay a foundation for exploring the molecular mechanisms of combined IFN-beta and TRAIL anti-tumor activity.

ABSTRACT

Objective To evaluate the CT features and the role of CT in the diagnosis of Crohn′s disease. Methods CT manifestations of 18 patients with pathology confirmed Crohn′s disease were retrospectively analyzed. The majority of the patients were scanned with spiral CT or multidetector row CT.Results All 18 patients, segmental thickening of the bowel wall was detected. There were two different appearances in contrast-enhanced CT scans: (1) mural thickening without enhancement or mural stratification, and homogeneous attenuation in the thickened wall were observed in 7 patients; (2) mural thickening and stratification, resulting in the target or double-halo appearance, were detected in 11 patients, and the bowel wall thickening ranged from 5 to 10 mm. Nine patients had perienteric abnormalities including fibrofatty proliferation, phlegmon and mesenteric hypervascularity. According to the CT manifestations, 5 patients were initially diagnosed as other diseases including intestinal obstruction (1 case), tuberculosis (1 case), cancer (2 cases), and abscess (1 case), respectively. Conclusion CT has the unparalleled ability to depict the abnormalities in the bowel wall, mesentery, abdominal and pelvic viscera, and contrast-enhanced CT can distinguish active Crohn′s disease from quiescent Crohn′s disease. These features make CT particularly valuable in the management of Crohn′s disease.

ABSTRACT

Objective: The effect of oil of Hippophae rhamnoides (OHR) supplements on sGOT,metabolism of free radical and ultrastructure of myocardium was observed in mice.Methods: 70 male ICR mice were randomly divided into six groups: sedentary control group (SCG), sedentary+OHR group (SHG), immediately after exhaustive exercise in control group (IEC) and in OHR group (IEO), 24 hours recovery after exhaustive exercise in control group (REC) and in OHR group (REO). After 6 w swimming program with gradually increasing intensity, these mice carried out an exhaustive swimming before sacrifice. Serum GOT, SOD and MDA in myocardium were measured and the changes of ultrastructure of myocardium were observed by transmission electron microscope (TEM). Results: 1) Serum GOT was significantly different among these groups except between SCG and SHG, IEC and REC. 2) SOD was significantly different among the above groups except between SCG and SHG, IEO and REO. 3) The concentration of MDA was significantly different among the above groups except between IEC and IEO, REC and REO. 4) The integrity of mitochondrion, rough surfaced endoplasmic reticulum and myofilament in myocardium was better in OHR groups than in control groups and the pathological tendency of these ultrastructures was lighter in OHR groups compared with control groups. Conclusion: OHR supplementation can reduce the damage of myocardium caused by exercise and enhance antioxidative status of myocardium; OHR supplementation can protect the ultrastructure of myocardium.
