The feasibility and mechanism study on intravenously injected bone marrow mesenchymal stem cells (MSCs) improving bladder function after spinal cord injury (SCI) were discussed by review the biological characteristics of MSCs, the changes and mechanism of the lower urinary tracts after SCI, and the study on the MSCs promoting recovery of bladder function.

Objective To investigate the adherence mechanism of Candida albicans to host cells in molecular level. Methods and Results Yeast cell wall protein of Candida albicans were extracted, and purified fibronectin (Fn) adhesin was obtained from yeast cell wall extract. Fn adhesin was analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE), the molecular weights of Fn adhesin were 60kd and 105kd. In order to find out the effect of the protein on adherence to host cells, human buccal epithelial cells and Candida albicans cells were incubated at 37℃ for 2 hours on a rotator, and yeasts adhering to the surfaces of epithelial cells were assayed microscopically. The adherence rate of C.albicans to buccal epithelial cells was 44 7?6 28%, and after treating the epithelial cells with Fn adhesin, the adherence rate reduced to 28 3?6 18%, P

With the advances in techniques of localization, numerous minimally invasive parathyroid surgery were developed including open minimal incision and endoscopic approaches. According to the research results and the experiences from Peking Union Medical College Hospital, the indication and preoperative preparation were discussed in this paper. Some suggestions were given for minimally invasive parathyroid surgery in China.

Objective To understand the effect of curcumin and TSA on c-myc gene expression in human gastric cancer and to explore the dynamic balance of the histone acetylation / deacetylation in gene expression in gastric cancer and the significance of the regulation. Methods Gastric cancer cell line SGC-7901 and MGC803 were cultured,and then different concentrations of histone acetylase inhibitors curcumin and histone deacetylase inhibitor TSA were added,respectively.mRNA of c-myc expression wasdetected by RT-PCR. Results With increasing of the concentration of curcumin and redcuing of the TSA concentrations c-myc expression was inhibited (P

Objective Clinical investigation of treatment of osteoporotic vertebral compression fractures by unilateral kyphoplasty.Methods After Surgical intervention of sixteen vertebral compression fractures by unilateral kyphoplasty,then investigate the changes of height and Cobb angle of vertebral bodies.Results All surgical procedures were finished safely.The mean height of the anterior and media vertebral bodies was 1.8?0.3cm,1.4?0.4cm preoperatively and 2.2?0.4cm、2.3?0.3cm postoperatively;the Cobb angle was decreased from 28.4??10.2? preoperatively to 19.2??4.5? postoperatively.The mean absolute value of the difference in height between right and left side of the vertebral bodies was 0.1cm in this group.Conclusions The kyphosis is improved and the operative time is reduced by unilateral kyphoplasty.Though this result is satisfied,more clinical studies are needed to be done for authenticating the effect of unilateral kyphoplasty on the treatment of vertebral compression fractures in the future.

Objective To develop the formulation of self-microemulsifying drug delivery system for hawthorn leaves flavonoids (HAW-SMEDDS). Methods The optimum formulations of oil phase, surfactant, and assistant surfactant for HAW-SMEDDS were screened by solubility test, compatibility test, and pseudo-ternary phase diagrams, with the time of formulating microemulsion, the consequence of visual examination, and particle size as indexes. The dissolution of HAW-SMEDDS was measured, taking the commercial tablet Yixintong Tablet as reference. Results The optimum self-microemulsifying drug delivery system was composed of Labrasol (35%), Transcutol P (10%). The particle diameter was (39.5?5.4) nm, the time of self-microemulsifying was less than 1 min. The percent of accumulated dissolution of hawthorn leaves flavonoids in SMEDDS in distilled water was up to 70% at 10 min, while that in the Yixintong Tablet was less than 50% at 60 min. Conclusion The formulation of HAW-SMEDDS preparation could meet the request of the design. It could provide the reference for the new dosage form.

Objective To study the anticoagulation effects of Supplemented Salvia Beverage (SSB) on myocardial ischemia in rats. Methods Rat myocardial ischemia model was induced by occluding the left anterior descending coronary artery,the effects of SSB (8.24,4.12,2.06 g/kg) on the activated partial thromboplastin time (APTT),prothrombin time (PT),thrombin Time (TT),platelet adherence rate,platelet aggregation,length of thrombus and the dry and wet weight of thrombus,as well as amount of Fibrinogen (Fg) were observed. Results Compared with model group,the shortening of PT and TT,and the decrease of Fg were obviously suppressed in high dosage SSB group (P

BACKGROUND: The feasibility and the mechanism of human umbilical cord blood mesenchymal stem cel transplantation for the treatment of liver cirrhosis need to be discussed in-depth. OBJECTIVE: To observe the effect of human umbilical cord blood mesenchymal stem cel transplantation through portal vein on the liver function and tissue pathological changes of the rats with liver cirrhosis. METHODS: Carbon tetrachloride was used to prepare rat model of liver cirrhosis. After the success of modeling, the rats in the cel transplantation group received portal vein injection of 1 mL 5-bromo-2-deoxyuridine -labeled human umbilical cord blood mesenchymal stem cells (5×106), the model group was injected with the same volume of PBS; the normal rats received 1 mL human umbilical cord blood mesenchymal stem cel transplantation via the portal vein were as the control group. At 4 weeks after transplantation, the rat tail vein blood and liver tissue were obtained for testing. RESULTS AND CONCLUSION: At 4 weeks after cel transplantation, compared with the model group, levels of serum alanine aminotransferase, aspartate aminotransferase and total bilirubin in the cel transplantation group were significantly decreased, while the albumin level was increased significantly (P < 0.01); the liver cel inflammatory necrosis, steatosis and liver fibrosis were improved significantly (P < 0.05 or P < 0.01). Immunohistochemistry and immunofluorescence staining showed that human umbilical cord blood mesenchymal stem cel colonization could be seen in the rat liver tissues of the cel transplantation group and control group, but the number of 5-bromo-2-deoxyuridine-positive cells in cel transplantation group was significantly larger than that in the control group. Reverse transcription-PCR test result showed that the expressions of cytokeratin 18 and albumin mRNA could be observed in the rat liver tissue of the cel transplantation group, but no expression could be seen in the control group. It is visible that human umbilical cord mesenchymal stem cells can improve liver function and pathological damage of liver cirrhosis rats in a certain extent, which may relate with the intrahepatic homing colonization and hepatocyte-like cel differentiation of the transplanted cells in the liver cirrhosis rats.
