The pure squalene(99.9%) was separated from liver oil of Mustelus griseus(Pietschmann) by TLC on silver nitrate-impregnated silica gel. The structure of squalene was confirmed by MS, ~1H-NMR and ~(13)C-NMR techniques.

BACKGROUND:There are most single-center studies about bone marrow stem cels applied to treat decompensated cirrhosis, but the therapeutic results are not ideal. It is possibly related to aging, physical weakness, poor bone marrow hematopoietic function, less available number of stem cels and feeble ability of regeneration and proliferation in liver cirrhosis patients. Umbilical cord mesenchymal stem cels are characterized of easy to obtain, wide source and weak immunogenicity. Co-transplantation of bone marrow stem cels and umbilical cord mesenchymal stem cels may improve the therapeutic effects on decompensated cirrhosis patients. OBJECTIVE:To investigate the efficacy and safety of co-transplantation of umbilical cord mesenchymal stem cels and bone marrow stem cels on decompensated cirrhosis.METHODS:Thirty-two decompensated cirrhosis patients were randomly divided into two groups: in stem cel group, 13 patients received co-transplantation of umbilical cord mesenchymal stem cels and bone marrow stem cels based on regular medical treatment; in control group, 19 patients only underwent the regular medical treatment. Al the patients were folow-up for 1 year. Alanine aminotransferase, albumin, total bilirubin, prothrombin time, Child-Pugh score and Model for End-Stage Liver Disease score, 1-year survival rate, Quality of Life score and adverse reactions related to stem cel therapy were observed and recorded in the two groups at 4, 12, 52 weeks after treatment. RESULTS AND CONCLUSION:At 4, 12, 52 weeks after treatment, improvements in the liver function, prothrombin time, Child-Pugh score and Model for End-Stage Liver Disease score were found in the two groups, but there was no difference between the two groups (P > 0.05). At 4 weeks after transplantation, the clinical symptoms and Quality of Life score in the stem cel group were significantly improved, which were better than those in the control group (P < 0.05). But at 12 and 52 weeks after treatment, no difference was found between the two groups (P > 0.05). In addition, the 1-year survival rate showed no difference between the two groups, and no severe adverse reactions related to stem cel therapy occurred during the folow-up. Co-transplantation of umbilical cord mesenchymal stem cels and bone marrow stem cels is safe and effective to improve the clinical symptoms of decompensated cirrhosis patients. However, further studies with larger samples are warranted to better clarify the co-transplantation effects.

Objective To explore the clinical curative effect of pre cut type perforated patellar needle combined with tension band steel wire internal fixation minimally invasive in the treatment of patellar transverse fracture. Methods A total of 67 cases of patients with patellar transverse fracture were treated with pre cut with holes patellar needles com-bined with tension band wire fixation of minimally invasive, the fracture degree,joint activity,knee functional score and incidence of complications were observed and analysised. Results Postoperative knee function score, the excellent and good rate was 92.5%was significantly higher than the preoperative 9.0%,postoperative knee activity, excellent rate was 90.0% significantly higher than the preoperative 6.0%,postoperative X piece shows the alignment score the excellent rate of 100%was significantly higher than the preoperative 11.0%fractures ,the differences were statistically significant (P<0.05),the incidence of complications of patients was 9.0%. Conclusion Pre cut type perforated patellar needle combined with tension band steel wire internal fixation minimally invasive in the treatment of patellar transverse frac-ture is be conducive to the fracture and recover the function of knee joint,the incidence of complications of patients is low, witch is the practical operation in treatment of patella fracture.
