Moreover , recent studies also found that the concentration of the miRNAs enfolded in the microvesicles is higher than that of the miRNAs in the plasma , which means that the microparticles are the main form of miRNAs present in peripheral circula -tory system.This article is to review the recent research progress in microparticle-encapsulated miRNAs and their regulatory effect on endothelial cell injury .

OBJECTIVE To investigate the relationship of obstructive sleep apnea hypopnea syndrome (OSAHS) and hyperglycemia by analyzing the level of blood-fasting sugar (BFS) in patients with OSAHS. METHODS The data of BFS and AHI in patients with OSAHS (n=300) and the data of BFS of controls (n=225) were collected. The difference of high blood glucose in the OSAHS and the controls.and the difference of AHI between OSAHS patients with high blood glucose and OSAHS patients with normal blood glucose was analyzed. RESULTS There were 97 patients (32.3 %) with high BFS in 300 OSAHS patients, but only 14 cases (6.2 %) with high BFS in 225 controls. There was a significant difference between two groups. The average of AHI in OSAHS patients with high BFS was 67.8/h, and average of AHI in OSAHS patients with normal BFS was 38.4/h. There was a significant difference between the two groups. CONCLUSION There is a close correlation of OSAHS and hyperglycemia.

Objective The purpose of this study is to observe the property of guided bone regeneration by collagen membrane and investigate the mechanism of guided bone regeneration. Methods 10mm defect of radius was created bilaterally in adult New Zealand rabbits. The experimental group was transplanted by collagen membrane with surface decalcified bone allograft,and the control group was transplanted by surfaced decalcified bone allograft alone.Radiological and histological and immunohistochemical examinations were taken postoperatively. Results In the transplantation area of experimental group,distinctive periosteal reaction and new bone growth occurred remarkably,bone remodeling progressed successfully,and defects healed completely.But in the transplantation area of the control group,new bone growth and mature bone replacement were delay due to occupation of fibrous connective tissue. Conclusions Collagen membrance has an ability to block and guide.In addition,membrane tube can keep endogenic BMP with exogenic BMP greatly concentrating and effectively distributing. The distributive characteristic of BMP exerts an influence on cellular resources and pattern of bone healing.

Background and purpose:Irinotecan plus fuorouracil/Leucovorin has become the standard regimen as the first-line in treating advanced colorectal cancer.We investigated the clinical response and side-effects of the first-line treatment with Irinotecan plus fuorouracil/ leucovorin(FOLFIRI) for advanced colorectal cancer.Methods:From may 2001 to march 2005,37 patients with advanced colorectal cancer were treat with irinotecan 180mg/m~(2) i.v.on day 2,and fuorouracil 400 mg/m~(2),bolus on day 1,2 and 1200 mg/m~(2),civ.44hour;leucovorin 200 mg/m~(2) i.v.on day 1,2,two weeks per cycle.Results:The response rate was 41.7%.Incidence of III/IV Grade myelosuppression was 35.1%/8.1%,and 4 patients suffered from febrile neutropenia.Incidence of III Grade delayed diarrhea was 8.1%.Conclusions:The first-line chemotherapy with a combination of irinotecan and fuorouracil/ leucovorin is effictive and well tolerated by patients with advanced colorectal cancer.

As an oral chemotherapy drug, capecitabine is safe, effective and easy to use, has been widely used in the treatment of esophageal cancer, gastric cancer, colorectal cancer, breast cancer, ovarian cancer and other solid tumor.The chemotherapy scheme is mainly for 3 weeks, each cycle of capecitabine for 14 days, and 7 days off.As a modification to conventional chemotherapy, the biweekly scheme with capecitabine showed low toxicity and well tolerated by patients, short hospitalization time and other characteristics, it is worth of application in clinical.

OBJECTIVE: To observe the effects of Qingdan Capsule (QDC) and Yanggan Lidan Granule (YGLDG), two kinds of compound traditional Chinese herbal medicines, on biochemical parameters in guinea-pigs with pigment gallstones. METHODS: An animal model of pigment gallstones was established in male guinea-pigs by hypodermic injection of lincomycin. The guinea-pigs were randomly divided into blank control group, untreated group, QDC group and YGLDG group. There were 8 guinea-pigs in each group. After ten-day treatment, animals were sacrificed and sampled to calculate the rate of stone formation, total bilirubin (TB), unconjugated bilirubin (UCB) and Ca2+ density in bile of the four groups. RESULTS: In comparison with the untreated group, the rates of stone formation in the QDC and YGLDG groups were significantly decreased (P<0.01). TBIL, UCB and Ca2+ content of bile in both QDC and YGLD groups was also significantly decreased (P<0.05, P<0.01). CONCLUSION: QDC and YGLD have good effects on biochemical changes of animal model of pigment gallstone in reversing the lithogenesity of bile by reducing the content of TB, UCB and Ca2+, hence resulting in clinical treatment and prevention of pigment gallstone disease.

BACKGROUND:The incidence of open fracture of the elbow joint is increased rapidly with an increased number of accidents. Fractures are often accompanied by severe soft tissue injuries. At present, a combined therapy of autologous skin grafting, vacuum sealing drainage and external fixation for the treatment of open fractures has been widely reported. OBJECTIVE:To investigate the characteristics of the combined therapy of autologous skin grafting, vacuum sealing drainage, and external fixation for repair of complex and severe open fracture of the elbow joint. METHODS:A total of 41 patients with complex and severe open fracture of the elbow joint who received the combined therapy of autologous skin grafting, vacuum sealing drainage and external fixation during January 2009 to December 2013 in General Hospital of Tianjin Medical University, China were selected. Al patients were treated with routine debridement, external fixation and vacuum sealing drainage to cover wound during the first period. During the second period, autologous skin grafting or flap transfer was used to repair wound when the fresh granulation tissue covered the wound. RESULTS AND CONCLUSION:The postoperative folow-up period of these 41 patients was 8-22 months, with an average period of 13 months. External fixation period was 8-13 months with an average period of 9.8 months. The open wounds were completely healed after autologous skin grafting or skin flaps transfer. Fractures were healed in 31 patients during the first period. There were 7 cases of delayed union, 3 cases of nonunion. Al fractures were completely healed during 8-12 months after iliac bone grafting. The excelent and good rate of limb function recovery was 73.1% among 41 patients with severe open fracture of the elbow joint. The limb function of Gustilo II patients better recovered. These results suggest that the clinical effect of the combined therapy of autologous skin grafting, vacuum sealing drainage and external fixation for the treatment of complex and severe open fractures of the elbow joint is satisfactory.
