Japan has accumulated much mature experience in hospital management, which is worthy of being drawn upon by hospital managers in China. By means of an account of the model of ward rounds by doctors at three levels, the system of academic previews and the system of regular meetings for copying down and reading medical papers in foreign languages in Japanese hospitals and in light of the situation of domestic hospital management, the paper discusses measures for improving the system of ward rounds and scientific research management. The goal is to enhance the medical expertise levels, scientific research capabilities and foreign languages proficiency of medical workers in China so as to deliver better medical and healthcare services to the broad masses of the people.

OBJECTIVETo report a case of simple congenital bilateral ejaculatory duct absence (EDA) complicated with seminal vesicle cyst and review the relevant literature in order to improve the diagnosis and treatment of the disease.

METHODSWe retrospectively reviewed the clinical data of a case of bilateral congenital EDA complicated with seminal vesicle cyst, reviewed the relevant literature at home and abroad, and comprehensively analyzed the embryonic development, diagnosis, and treatment of congenital EDA.

RESULTSThe patient was a 23-year-old man, present at the clinic for infertility after married for a year. Vasography and other imaging examinations confirmed simple congenital bilateral EDA complicated with seminal vesicle cyst. Pathologic biopsy showed normal spermatogenic function of the testes.

CONCLUSIONCongenital EDA originates from embryonic developmental defect of the mesonephric duct, and it can be confirmed by vasography. Transurethral incision of the ejaculatory duct and intracytoplasmic sperm injection can be employed for the treatment of bilateral EDA.

Chlorella pyrenoidosa No.2 was screened from five species of microalga Chlorella sp. for its higher lipid yield. Effects of medium components and culture conditions on cell growth as well as lipid ac-cumulation of C. pyrenoidosa No.2 were investigated and the results showed that the optimum medium rec-ipe was 20.0 g/L glucose,0.08 g/L glycine,1.0 g/L K2HPO4?3H2O,0.4 g/L MgSO4?7H2O and 0.004 g/L FeSO4?7H2O. The optimum culture temperature,initial pH,shaking rate and light intensity were 28℃,6.0,130 r/min and 650 Lux,respectively. Biomass and lipid content increased from 3.73 g/L and 40.15% to 6.56 g/L and 59.90% when Chlorella pyrenoidosa No.2 was cultivated under the above optimal conditions for 7 days,with lipid yield raised by 162%. Chlorella pyrenoidosa No.2 could produce lipid with xylose as carbon source,and so is potential for lipid production from renewable materials such as lignocellulose. GC analysis demonstrated that the fatty acid composition of the lipid was similar to that of vegetable oil and its unsaturated fatty acid content reached around 71%,thus it is a promising material for biodiesel production.

Objective To investigate the enhanced osteogenesis during bone fracture healing after intracerebroven-tricular (ICV) leptin injection, using rabbit model with created segmental bone defect in right tibial. Method Segmental critical-sized defects were created at the right tibial bone of skeletally mature New Zealand white rabbits. In experiment group (leptin group), recombinant rabbit leptin was injected into cerebellomedullary cistern through foramen magnum. While in control group, normal saline was injected in the same way. Bone Mineral Density (BMD) was evaluated by qCT at 1st, 3rd, 7th, 14th and the 21st days. At the 21st days, all rabbits were euthanized to collect the right tibia for histomorphology, to ex-amine the BMP-2 expression in the bone callus by Fluorescence in situ hybridization (FISH). Result In the leptin group, body weight declined more obviously than control group then it start to arise at the 14th day;qCT showed significant higher BMD in leptin group than in control group at the 7th day;FISH showed a higher BMP-2 expression in leptin group than in control group. Conclusion Cerebellomedullary leptin injection through foramen magnum could accelerate limb fracture healing in rabbit model with right tibial bone defection.
