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.

AIM: To observe the effect and safety of applying mitomycin C ( MMC ) in laser - assisted subepithelial keratomileusis ( LASEK) for extreme high myopia.
●METHODS:LASEK with 0. 02% MMC was performed in 364 eyes of 182 patients with extreme high myopia and spherical equivalent was-9. 0 to-10. 25 D. All the patients were divided into four groups according to the applying time of MMC. The time in Group l was 10s, in GroupⅡwas 25s, in Group Ⅲ was 40s and 55s in Group lV. Uncorrected visual acuity ( UCVA ) , residual refraction, Haze, healing time of corneal epithelium, density and variant index of corneal endothelium was examined in these patients and follow-up 6mo.
●RESULTS:At 6mo after surgery, 76. 3%, 94. 0%, 92. 3%and 93. 8% of the patients in Group l, GroupⅡ, GroupⅢ and Group lV respectively achieved the UCVA better than 15/20. There was significant difference of UCVA between Group l and the other three groups (χ2=19. 610, P=0. 000). Proportion of the residual refraction between ± 0. 5D in Group l (78. 8%) was lower than other groups (95. 2% in Group Ⅱ, 93. 3% in Group Ⅲ, and 92. 7% in GroupⅣ) at 6mo and there was significant difference (χ2=16. 329, P=0. 001). Group l had more Haze statistically than the other three groups at 6mo postoperatively ( Hc=50. 110, P=0. 000). The healing time of cornea epithelium seem to be no statistically difference between each group at 6mo (χ2=11. 611, P>0. 05). MMC had no influence on the density of corneal endothelium in each group postoperatively (P>0. 05), there were 3071. 3±284. 4 cells/mm2 in Group l, 3 105. 6 ± 337. 8 cells/mm2 in Group Ⅱ, 2 986. 3 ± 304. 1cells/mm2 in Group Ⅲ and 3 088. 7 ± 372. 5 cells/mm2 in Group lV respectively. The variant index of corneal endothelium calculated in each group at 6mo after surgery was 24. 72 ± 6. 52, 22. 93 ± 6. 74, 24. 38 ± 6. 63 and 23. 14±7. 22 repectively, compare with that preoperatively there were no statistically differences (P>0. 05).
●CONCLUSION: For extreme high myopia LASEK with 0. 02% MMC is effective and safe. The MMC applying time of 25s in LASEK can effectively reduce Haze after surgery and decrease potential complications.
