Bone marrow-derived mesenchymal stem cells(BMSCs)exist in and can be isolated from the bone marrow of adult human being and animals and can be induced to differentiate into different cells.They are easy to be isolated,cultivated,and amplified.They are also less immunogenic in the body and can avoid ethical dispute when applied in transplantation.Studies have shown that BMSCs can be induced to differentiate into neural cells under certain conditions in vitro.This article reviewed the recent development in the research on the induction protocols for neural differentiation of BMSCs and the possible mechanisms.

Objective To analyze the factors influencing the outcome in a frozen thawed embryo transfer (FTET)program Methods Sixty FTET cycles performed in 53 cases from September 1997 to May 2000 were analyzed retrospectively The related parameters were compared between the conceived and non conceived cycles Results One hundred and seventy eight out of 252 thawed embryos were survival Embryo transfers were undergone in 57 cycles (53 patients), resulting in 17 pregnancies (30% per transfer or 28% per thawed cycle) There were no significant difference between conceived and non conceived cycles in terms of the controlled ovarian hyperstimulation protocols, numbers of developed follicle and oocyte retrieved, fertilization rate, numbers of frozen embryo and the luteinizing hormone, estradiol, progesterone levels on human chorionic gonadotropin triggering day The percentage of good quality embryo before freezing and after thawing and survival thawed embryos were higher in conceived cycles than those in non conceived cycles (83 8% Vs 60 7%, 76 8% Vs 50 0%, 82 4% Vs 66 3%, respectively P

Objective To synthesize a new reagent, 1-(6-bromo-2-benzothiazolyl)-3-(5-bromo-8-quinolyl)-triazene (BBTBQT) and apply to the determination of cobalt. Methods The reagent had been synthesized by diazotization and coupling reaction. After purification and characterization, BBTBQT was tested for its color reaction conditions with cobalt in the presence of cetylpyridinium bromide (CPB). Results In the presence of borax buffer solution at pH value of 9.0, the reagent reacted with cobalt to form a blue stable complex with a molar ratio of 2∶1; the complex had a maximum absorption at 640 nm. The apparent molar absorptivity of the complex is 1.55 ?105 L/(mol?cm). Beer’s law was obeyed in the range of 0-0.28 mg/L for cobalt. The method had been applied to determine cobalt in drainage sediment and vitamin B12 injection solution with a mean relative error of 1.9%-5.8% and a standard relative deviation of 1.7%-3.8%. Conclusion The present method is selective, sensitive, accurate, convenient and suitable for determination of trace cobalt in the samples.

Objective To analyze the radiographical and histological features of implanted composites of decalcified bone matrix(DBM) impregnated with calcium phosphate cement(CPC) and recombinant human bone morphogenetic protein-2(rhBMP-2) in bone defect,and evaluate its biodegradation properties.Methods By prefabricating the rabbit DBM,the CPC/DBM/rhBMP-2 composites were prepared in a DBM/CPC ratio of 2∶8 and the rhBMP-2 content of about 1.2mg/cm3.Twenty-four rabbits were divided into groups A and B(12 each).Animals in group A were implanted with the composites in the bone defects at femoral condyle and femoral muscle,and the rabbits in group B CPC was implunted in the same place.Animals were sacrificed at 6,12 and 24 weeks after operation(4 each),and the implants were examined radiographically and histologically.Results It was shown by radiography that,in group A,the margin of implants in femoral condyle defects became irregular 6 weeks after operation;the appearance of the implants appeared hazy and shrunken in size 12 weeks after operation;and most of the implant was absorbed and the medullary cavity became partly rediotransparent 24 weeks after operation.The density of the implants in muscles beoame less dense gradually during 6 to 24 weeks after operation.While in group B,the appearance and density of the implants in femoral condyle defects and muscles were not obviously changed during 6-24 weeks after operation.Histological observation showed that,in group A,the interface between the implants in the bone defects was filled with newly formed bone grown into the composites 6 weeks after operation.New bone formed inside the composites 12 weeks after operation,and the bone defect was repaired,and most of the implants were replaced by new bones,with a little portion of it remained 24 weeks after operation.Fibrous tissue was seen to grow into the composites in muscles during 6-12 weeks after operation,and only a little of the composites remained 24 weeks after operation.In group B,no fibrous tissues or new bones grew into composites implanted in femoral condyle defects or muscles 6-12 weeks after operation,and the bone defects was still filled with materials of CPC,and no new bone or fibrous tissue was found inside CPC 24 weeks after operation.Conclusion Compare with CPC,the DBM with an optimal formula is are easy biodegradable and can be replaced by autologous bone.

OBJECTIVE:To evaluate the quality of TCM decoction pieces in our hospital preliminarily and explore the solu-tions for the problem of the quality of decoction pieces purchased by the hospital. METHODS:In Jun. 2012,a system was estab-lished by our hospital,where the quality inspector was designated to daily inspect new batches of TCM decoction pieces such as ap-pearance provided by suppliers. The batches of TCM decoction piece samples inspected and those of unqualified products from Jun. 2012 to May 2014 were calculated. The reasons of unqualified products were analyzed and corresponding solutions were made. RE-SULTS&CONCLUSIONS:Over two years,a total of 94 671 batches of TCM decoction piece samples were inspected by our hos-pital,among which 737 were unqualified products predominantly because of mildew,damage by worms,greasing,containing for-eign substances and others. The solutions to such problems included interviewing the suppliers,returning or discontinuing the use of crude drugs and special focus on particular seasons and on the demand for key varieties. The unqualified products rate in the quality inspection reduced from 0.56%in Jun. 2012 to 0.34%in May 2014. Therefore,setting the post of drug quality inspector in the hos-pital can ensure the quality of TCM decoction piece purchased,however,it need to improve the inspection and acceptance of quali-ty inspection by sampling,scoring and using the new technology.

Objective To investigate the clinical value of improved percutaneous tramhepatic cholangiographic drainage(PTCD)and percutaneous placement of biliary metallic stents on the treatment of malignant obstructive jaundice.Methods Thirty three patients with malignant biliary obstruction were treated by the improved PTCD guided by ultrasound followed by pereutaneous placement of biliary tract metallic stcnts 1～3 weeks later.Results Improved PTCD WaS succeeded in all the patients,30 patients(90.9%)accepted percutaneous placement of biliary metallic stents successfully,3 patients who failed in stents placement accepted PTCD again for palliative management of iallndice.Thofle who failed in stent placement were found to have bleeding from the PTCD tube,but recovered several days later.Jaundice alleviated in all the patients.The patients were followed up for 1～29 months,medium follow-up period is 14.8 months.Six cases were found lever and jaundice,among that,two ageepted improved PTCD again,one recovered after antibioic treatment,the remaining 3 patients failed in further treatment due to the metastasis of the tumor.Condusion Pereutaneous placement of biliary metallic stents after improved PTCD is a safe and effeetive method to relieve malignant biliary obstruction,it can improve life quality,prolong survival time.This method could be a good choice for treating the patients with mnlignant biliary obstruction without operation.
