Selenium-Containing Protein From Selenium-Enriched Spirulina platensis Attenuates High Glucose-Induced Calcification of MOVAS Cells by Inhibiting ROS-Mediated DNA Damage and Regulating MAPK and PI3K/AKT Pathways.

Hyperglycemia is the main feature of diabetes and may increase the risk of vascular calcification (VC), which is an independent predictor for cardiovascular and cerebrovascular diseases (CCD). Selenium (Se) may decrease the risk of CCD, and previous studies confirmed that Se-containing protein from Se-enriched Spirulina platensis (Se-SP) exhibited novel antioxidant potential. However, the effect of Se-SP against VC has been not investigated. Herein, the protective effect and underlying mechanism of Se-SP against high glucose-induced calcification in mouse aortic vascular smooth muscle cells (MOVAS) were explored. Inductively coupled plasma atomic emission spectroscopy (ICP-AES) results showed time-dependent uptake of Se-SP in MOVAS cells, which significantly inhibited high glucose-induced abnormal proliferation. Se-SP co-treatment also effectively attenuated high glucose-induced calcification of MOVAS cells, followed by decreased activity and expression of alkaline phosphatase (ALP). Further investigation revealed that Se-SP markedly prevented reactive oxygen species (ROS)-mediated DNA damage in glucose-treated MOVAS cells. ROS inhibition by glutathione (GSH) effectively inhibited high glucose-induced calcification, indicating that Se-SP could act as ROS inhibitor to inhibit high glucose-induced DNA damage and calcification. Moreover, Se-SP dramatically attenuated high glucose-induced dysfunction of mitogen-activated protein kinases (MAPKs) and phosphatidylinositol-3-kinase/AKT (PI3K/AKT) pathways. Se-SP after Se addition achieved enhanced potential in inhibiting high glucose-induced calcification, which validated that Se-SP as a new Se species could be a highly effective treatment for human CCD.

[Diagnosis and treatment of schistosomiasis japonica-concensuses among ex- perts in Hunan, Hubei and Jiangxi provinces].

In order to further standardize the diagnosis and treatment of schistosomiasis japonica in China, on the basis of evidence-based medicine, the experts on schistosomiasis control from Hunan, Hubei and Jiangxi provinces summarized their consensuses on the disease after the discussion on the current situation and progress of clinical diagnosis and treatment of schistosomiasis in China, with the reference to the Diagnostic Criteria for Schistosomiasis (WS261-2006), which aimed to establish the therapeutic standards or guideline of schistosomiasis in China.

[Endoscopic ligation in treatment of advanced schistosomiasis patients with esophageal variceal bleeding: a report of 68 cases].

OBJECTIVE: To evaluate the therapeutic effect of endoscopic ligation in the treatment of advanced schistosomiasis patients with esophageal variceal bleeding. METHODS: A total of 130 advanced schistosomiasis patients with esophageal varices rupture and bleeding were divided into a ligation group (68 cases) and a control group (64 cases), and the patients of ligation group were treated with the emergency endoscopic ligation, and the patients of control group received the routine therapy. The rebleeding rate, hemostatic success rate, and varicose veins red color sign were observed. RESULTS: In the ligation group, the rebleeding rate was 10.3% and the positive rate of varicose veins red color sign was 8.8%, which were better than those in the control group (both P values <0.01). CONCLUSION: Endoscopic ligation is an effective therapy for esophageal variceal bleeding.

[Recommendation of a new clinical classification of advanced schistosomiasis].

OBJECTIVE: To recommend a new clinical classification of advanced schistosomiasis for improving the diagnosis and evaluation of therapeutic effect of advanced schistosomiasis. METHODS: The medical records of 11 092 cases of advanced schistosomiasis from the Xiang-Yue Hospital from January 1990 to January 2010 and the medical aid centre for advance schistosomiasis in Hunan Province from January 2004 to January 2010 were collected and classified with the current and new clinical classification methods and the results were statistically analyzed and compared. RESULTS: Based on the current classification method, there were huge splenomegaly (5 710 cases), ascites (2 993 cases), colon proliferative (834 cases), and dwarf (54 cases). However, 1 501 cases were excluded from the current classification. Based on the new classification method, there were 8 types: huge splenomegaly (2 870 cases), ascites (1 885 cases), colon proliferative (425 cases), dwarf (38 cases), universal (1 281 cases), bleeding (1 857 cases), hepatic coma (553 cases), and miscellaneous (1 759 cases). Totally 424 cases were classified into chronic schistosomiasis. CONCLUSION: The new classification method can present a more comprehensive picture for clinical features, severe complications and prognosis of advanced schistosomiasis, and is useful for the diagnosis and treatment of advanced schistosomiasis.
