Objective To observe the effect of Diosmin Tablets about the prevention and treatment of edema that breaks out after a circular mixed hemorrhoids operation and the role of fibrosis on edema.Methods Having 120 cases of circular mixed hemorrhoid patients, Acco 60 cases were randomly divided into treatment group and the others were in comparison group.Both groups were outside the cut line of circular mixed hemorrhoid ligation within the injection, after these operations do conventional anti-inflammatory, hemostasia and local Ma Ying Long musk hemorrhoids ointment medication.The next day of the operation, the treatment group take a dose of Diosmin tablets 1.5 g bid 4 d, then changing the dose 1 g bid 3 d.ResultsThe incidence of edema, treatment group was 6.6% and the other group was 30%.edema in the incidence of the two groups were significantly different(P ＜ 0.01).The treatment group non-fibrosis, but the other group have 4 patients getting fibrosis.The two sets of rate about edema fibrosis were significantly different(P ＜ 0.01).Conclusion Diosmin Tablets can effectively do prevent and disperse circular mixed hemorrhoid postoperative edema.

Objective To detect the levels of Th1 and Th2 type cytokines of peripheral blood CD+4 T lymphocytes in the patients with cervical cancer in order to find out the laboratory evidence of tumor immunotherapy. Methods The peripheral blood lymphocytes were stimulated by stimulator in order to enhance expression of cytokines. Then specific fluorochrome-conjugated monoclonal antibody was added to be combined with its specific antigen. Results The level of IL-2 produced by Th1 cells were lower in patients of cervical cancer than those of normal controls, there were significant difference between them. But the level of IFN-? produced by Th1 cells had no significant change in patients of cervical cancer in comparison with normal controls. The levels of Th2 type cytokines such as interleukin-4(IL-4), interleukin-6(IL-6), interleukin-10(IL-10) were higher in patients of cervical cancer than those of normal controls, there were significant difference between them. Conclusion Th1/Th2 is imbalance in cervical cancer .Th1 type cytokines are inhibited, and Th2 type cytokines are relatively enhanced, so Th1/Th2 shifts to Th2. It may be the mechanism of tumor arising and transferring by immune escape from immunosurveillance.

After being introduced to Japan, the Chinese acupuncture and massage therapy has changed a lot, in which the influence aroused by the blind practitioners cannot be ignored. Through analyzing the development and the transition of the blind acupuncture and massage industry in Japan, it is found that the tube needle technique, changeable acupoints concept, technical deviation and the importance on acupoints rather than meridians are still existed commonly today, which are introduced by the blind acupuncture and massage practitioners, the special group in Japan. In the process of development, the interaction with the governmental strategy has played the essential role in the consolidation of the above features.

BACKGROUND:Platelet lysate has been known as a kind of lysate of autologous or alogeneic platelet-rich products. It not only removes the residual cel structure, reduces immunogenicity, but also retains many growth factors. Platelet lysate has been suggested as a substitute for fetal bovine serum to expand mesenchymal stem cels in vitro. OBJECTIVE:To observe the effects of platelet lysate on biological characteristics of human bone marrow mesenchymal stem cels and adipose mesenchymal stem cels, and provide some experimental data for clinical cel therapy and regenerative medicine. METHODS:Platelet lysate was prepared by repeated freezing and thawing from fresh blood. Healthy adult bone marrow and adipose tissue were colected. Human bone marrow mesenchymal stem cels and adipose mesenchymal stem cels were obtained by density gradient centrifugation and type I colagenase digestion. We tested the morphology, cel phenotype, differentiation characteristics, proliferation capacity, colony forming ability and the level of cytokine secretion of bone marrow mesenchymal stem cels and adipose mesenchymal stem cels after cultured with platelet lysis. RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cels and adipose mesenchymal stem cels were successfuly cultured in vitro using platelet lysate. There were no significant differences in morphology, cel phenotype, colony forming ability and the level of cytokine secretion, and chondrogenic, osteogenic and adipogenic capacities between bone marrow mesenchymal stem cels and adipose mesenchymal stem cels. Adipose mesenchymal stem cels had a high cumulative population doublings than bone marrow mesenchymal stem cels (P < 0.05). These findings suggest adipose mesenchymal stem cels had a stronger proliferative ability, and are more suitable for large-scale expansionin vitro cultivation system of platelet lysate compared with bone marrow mesenchymal stem cels.

BACKGROUND:Mesenchymal stem cells have been an important source of seed cells for tissue engineering, regenerative medicine and immunosuppressive therapy areas. The large expansion is the key to the clinical application of mesenchymal stem cells. OBJECTIVE:To summarize the research progress in the in vitro expansion of human mesenchymal stem cells in animal serum-free media. METHODS:A computer-based online retrieval of CNKI and PubMed databases was performed to search papers published between 2004 and 2014 using the key words of“mesenchymal (stromal) stem cells, animal serum-free media, humanized media, human serum, umbilical cord blood serum, platelet rich plasma, platelet lysate, defined medium”in English and Chinese, respectively. Final y, 41 articles were retained. RESULTS AND CONCLUSION:Human serum, umbilical cord blood serum, platelet rich plasma, platelet lysate and defined medium can replace fetal bovine serum for large-scale expansion of mesenchymal stem cells in vitro. These media or additives have their advantages and disadvantages;therefore, it is urgent to guarantee the functional effectiveness and transplantation safety before large-scale, systematic clinical application of mesenchymal stem cells.

BACKGROUND:Bone morphogenetic protein 9 is proved to promote the osteogenic differentiation of various kinds of stem cel s, but whether it can induce the osteogenic differentiation of dental fol icle cel s in vitro is yet unclear. OBJECTIVE:To investigate whether bone morphogenetic protein 9 can induce the osteogenic differentiation of rat dental fol icle cel s in vitro. METHODS:Purified rat dental fol icle cel s at passage 3 were transfected with bone morphogenetic protein 9 adenovirus. Then, alkaline phosphatase activity, calcium deposition and expression of osteogenesis-related factors at mRNA and protein levels were detected in the dental fol icle cel s. RESULTS AND CONCLUSION:After transfection with bone morphogenetic protein 9, the dental fol icle cel s showed continuously enhanced alkaline phosphatase activities and obviously enhanced calcium deposition. Real-time PCR results demonstrated that the mRNA expressions of alkaline phosphatase, osteocalcin, bone sialoprotein, osteopontin and core binding factor were increased significantly. The western blot assay showed that the expression of osteopontin enhanced in the dental fol icle cel s after transfection with bone morphogenetic protein 9. In summary, bone morphogenetic protein 9 can induce the osteogenic differentiation of dental fol icle cel s.

Objective To observe the treatment of continuous passive motion(CPM) on talipes valgus in the chil-dren with cerebral palsy. Methods There were 57 children in this research including normal group and valgus group, the children in valgus group were randomly divided into control group, non-CPM group and CPM group. The control group didn’t receive any rehabilitation treatment. The non-CPM group received conventional rehabilita-tion treatment. The CPM group received conventional rehabilitation and CPM therapy. Evaluate the children in nor-mal group with plantar pressure analysis and evaluate each patient before treatment two and four months after treat-ment with plantar pressure analysis. Results Compared with the normal group, the percentage of medial midfoot (MMF) pressure, HEEL pressure, initial contact phase(ICP) and forefoot contact phase(FFCP) were obviously higher in valgus groups. On the other hand, the percentage of lateral forefoot ( LFF) pressure, lateral midfoot (LMF) pressure and foot flat phase(FFP) were obviously lower in valgus groups(P < 0. 05). The percentage of MMF pressure, and FFP became lower after treatment in both CPM group and non-CPM group while the percentage of ICP and FFCP became higher(P < 0. 05). In CPM group there was a more obvious change with the percentage of MMF pressure, ICP and FFCP compared with non-CPM group and the control group(P < 0. 05). Conclusion U-sing CPM can alleviate muscle spasms and contracture, correct the deformity of midfoot, enhance the muscle group coordination on foot and further more improve gait of patients with cerebral palsy.
