In this paper attempt has been made to observe the effect of Anordrin and its analogue SIPPR-113 on the morphological characters of uterine endometrium in mice implantation period and after castration. 100 mice were used in two experiments. The first experiment was performed in mice after mating, it included 5 groups as follows: control, estradial, progesterone, Anordrin and SIPPR-113 groups. The mice were treated with least doses (2-4mg/kg) which can prevent implantation on dayl-2 after mating. The animals were killed on the 5th day of pregnancy. The second, experiment contained also 5 groups: mature female mice were treated with 1/4-1/2 of above doses on the 25-26th day and were killed on the 29th day after castration. The uterine endometrium was embedded with paraffin and Epon812, histological sections and semi-thin sections (1ftm thick) and ultra-thin sections were made. They were observed under light microscope and electron microscope (Hitachi-600). Similar results were obtained in the two series of experiments. The endometrium had grown obviously and the numbers of glands and of cell's mitosis were increased, edema was indicated in stroma, as well as secretory function of glands was prevented period of implantation. Some lysosomes and lipid drops were found in the glandular cells and micro-filaments were observed in stromal cells under electron microscope. The effect of SIPPR-113 were similar to Anordrin, their anti-implantation action may be related to their estrogen and anti-progestrone action.

Lymphoma is a group of malignancies that affect lymphatic system of the body,and often originates from the abnormal cloned proliferation of B,T or NK cell lineage.It contains mainly two categories:Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL).The treatment options consist of chemotherapy,radiotherapy,immunotherapy and radioimmunotherapy,et al.It has been demonstrated that lymphomas are typically radiosensitive tumors and undergo apoptosis readily after radiation therapy(RT).RT produces very high local complete response rate for all lymphoma subtypes.This review will mainly focus on the role of RT in the treatment of aggressive lymphoma,indolent lymphoma,extranodal lymphoma and HL,as well as the application of modem RT techniques.

BACKGROUND:Studies have shown that under certain conditions, mesenchymal stem cels can be induced to differentiate into hepatocytes and promote local angiogenesis to generate new capilary network and build rich colateral circulation for the purpose of improvement and treatment of liver cirrhosis. OBJECTIVE:To review the latest advances in mesenchymal stem cel transplantation for the treatment of liver cirrhosis. METHODS:PubMed, CNKI, Wanfang and VIP databases were searched using keywords of marrow stem cels, hepatic cirrhosis in the title and abstracts for articles addressing mesenchymal stem cel transplantation for liver cirrhosis published from January 2000 to December 2014. Finaly, 53 articles were reviewed. RESULTS AND CONCLUSION:Mesenchymal stem cels have self-replication and multi-directional differentiation potential, and also possess paracrine and immune functions, which are ideal seed cels used for cel replacement therapy. At present, the techniques for isolation, culture, identification andin vitroamplification of mesenchymal stem cels have been quite mature, and animal studies have confirmed that umbilical cord mesenchymal stem cels is safe and effective to treat decompensated cirrhosis, which can fundamentaly treat target organ damage and improve liver function, but there are stil many clinical issues to be resolved.

BACKGROUND: The long-term cryopreservation of embryonic stem cells is an important link in its researches and application. Traditional protectants of cryopreservation often contain dimethyl sulfoxide, glycerine, animal serum, etc., but they cannot effectively ensure the survival rate of some cells, and even damage some functions of the cells.OBJECTIVE: To develop the suitable protectant for the cropreservation of mouse embryonic stem cells. DESIGN: An observational study.SETTINGS: Department of Physiology, Conghua College of Guangzhou Medical College; Sinocells Bio Technologies Co.,Ltd.MATERIALS: The experiment was carried out in the laboratory of Sinocells Bio Technologies Co.,Ltd. from October 2004 to September 2005. Mouse cell line mES-1 was given as a present by the Research Room of Cell Biology, Institute of Basic Medical Sciences, Academy of Military Medical Sciences of Chinese PLA.METHODS: The cells collected from cultured mES-1, a mouse embryonic stem cell line. Dimethyl sulfoxide was used as the main protectant for cryopreservation. There were four different groups according to different protectants. In the control group, the protectant for cryopreservation contained DMEM (high sugar), 10% dimethyl sulfoxide, 10% FBS,10 mg/mL ascorbicacid, 0.18 mg/mL inositol and 0.44 mg/mL folic acid; Besides, 7.56 mg/mL mannose in the mannose group, 34.23 mg/mL mycose in the mycose and 41.94 mg/mL saccharu in the saccharu group were supplemented respectively. The effects of different polyols on the survival rate and ability of multiple differentiation of mouse embryonic stem cells after cryopreservation were observed.MATN OUTCOME MEASURES: Formation rate of mouse embryonic stem cells colony; Formation rate of embryoid bodies.were all significantly decreased as compared with that before cryopreservation [control group: (24.0±8.8)%; mannose group: (42.0±10.1)%; mycose group: (84.0±8.2)%; saccharu group (70.0±14.2)%; before cryopreservation: (95.0±4.7)%,embryoid bodies in the mycose group was higher than those in the control group and mannose group [(90.0±5.2)%,(80.0±6.9)%, (82.0±9.6)%, P＜0.05], but had no significant difference as compared with that in the saccharu group.CONCLUSION: The protectant for cryopreservation by taking mycose as the main component can effectively maintain the abilities of self-renewing and multiple differentiation of mouse embryonic stem cells.

Objective To explore the effect of the application of Rivaroxaban in the treatment of the patients with total hip replacement.Methods 114 patients with total knee arthroplasty were randomly divided into control group and observation group,57 cases in each group.All patients were operated by the standard operation in the department of orthopedics.The control group was given low molecular weight heparin before operation.The patients in the observation group were treated with 8h after the operation,and the color Doppler ultrasound was performed on the patients with double lower limbs and lungs after 2 courses of treatment.Observation of drainage,two groups of patients after total blood transfusion,blood index,adverse reactions and deep vein thrombosis cases.Results In the observation group,the deep vein embolism rate (1.75%)was significantly lower than that in the control group of 12.28% (χ2 =4.25,P <0.05 );The postoperative drainage volume,blood transfusion and blood index of the two groups had no significant differences (t =0.57,0.82,1.03,all P >0.05).During the treatment,the patients in the two groups were adverse reactions.Conclusion The effect of oral administration of Rivaroxaban after hip replacement surgery is remarkable,which can effectively reduce the incidence of deep venous thrombosis,and it is safe,and it is worthy of clinical application.

Objective To study the prognosis of hepatoblastoma (HB) in children.Methods Retrospective analysis on the clinical data and follow-up of children with HB admitted from September 2010 to February 2015 and sum up the clinical outcome and prognosis.Results Thirty-six children with HB (23 males and 13 females) were enrolled. The median age on diagnosiswas 20 months. Allthe36 patients received follow-up, the median follow-up time was 37 months (7~71 months).(1) Of the 36 patients, 8 died. The prognosis of patients with stageⅠorⅡwas signiflcantly better than those with stage Ⅲ or Ⅳ(P<0.05). The prognosis of patients with fetal type was signiflcantly better than those with other subtypes (P<0.05). (2) Serum AFP level of 35 newly diagnosed cases increased, AFP level of survivors returned to normal after treatment. Of the 8 died patients, 3 patients had AFP elevated when relapsed, 5 cases had a persistently high AFP level after adjuvant chemotherapy. The levels of LDH, CRP, and AST at diagnosis had signiflcant influence on the prognosis (P<0.05).Conclusions Serum AFP can be a monitoring indicator for recurrence and prognosis of hepatoblastoma. POG / CCG staging, pathology classiflcation are key points when assessing the prognosis of hepatoblastoma. The prognosis of patients with high levels of LDH, CRP, and AST might be worse.
