Objective To explore the acquired deficiencies of vitamin K-dependent coagulation factors in etiology, clinical characteristics and treatment. Methods Retrospective analysis was performed on the data of etiology, clinical manifestations of 45 patients with acquired deficiencies of vitamin K-dependent coagulation factor. All patients were treated with Vitamin K1 10 -40 mg/d, i. v. , for three months. Some patients with severe blooding were additionally treated with fresh freezing plasma or prothromibin complex. Prothrombin time(PT) and activated partial thromboplastic time(APTT) were measured using Stago automatic blood coagulation analyzer before and after treatment. Ⅱ , Ⅶ, Ⅸ and Ⅹ were measured in some patients. Results Among the 45 cases, no certain cause was found in 19 cases (42.2%), anticoagulant rodenticides poison was a common cause ( 11 cases,42.3% ). The main presentations was hemorrhage, the most common bleeding sites were mucosa (77.8%) (35/45)and hematuria (46.7%) ( 21/45 ). After vitamin K1 treatment, PT and APTT had shortened remarkably from ( 110.35 ± 35.36 ) s,(98.91 ±48.98)s to (13.48 ±2. 17)s,(33.25 ±6.95)s,respectively(t=19.10 and 6.19,Ps <0.01)and the activities of factor Ⅱ、Ⅶ、Ⅸ、Ⅹ had rapidly increased from ( 17.48 ± 10.93 ) %, ( 10.23 ± 5.68 )%, ( 11.98 ±4.69)%,(12.93±7.48)% to (70. 12 ±21.31)%,(92.76 ±29. 15)%,(88.64 ±40. 21)%,(63.97 ±20.11)%(t=12.13,14.43,13.27and9. 74,respectively,Ps<0. 01).Conclusions The histories of patients with acquired deficiencies of vitamin K-dependent coagulation factors are usually hiding, therefore it is easily misdiagnosed. It is worth of detecting PT and APTT in diagnosis and monitoring. Using vitamin K1 10 -40 mg/d is effective and safety.

OBJECTIVEObserve and analyze the informations of western medicine and traditional Chinese medicine in patients with coronary heart disease (CHD), in order to provide reference for clinical treatment.
METHODSelect patients with CHD in diagnosis of the first place in 17 hospitals, drug informations of these patients were analyzed using frequency method and association rules.
RESULTIn 84 697 patients,there were 47 564 males and 32 882 females. The median age was 71 years old, 76 172 patients have medicine records, including 278 kinds of western medicine and 331 kinds of traditional Chinese medicine. Aspirin was the most common used western medicine (51 132 patients, 67.08%), followed by isosorbide dinitrate, clopidogrel etc. The most common used traditional Chinese medicine was danhong injection, followed by shuxuetong injection. After classified the drugs, at the forefront of western medicine were antiplatelet drugs, nitrates drugs, statins, beta blockers, calcium antagonists, ACEI; the most used in traditional Chinese medicine was injection of blood-activating and stasis-resolving, followed by oral preparations of blood-activating and stasis-resolving medicine, Fuzheng class oral medicine, purgation medicine etc. After association rules, combination therapy among western medicine was the most common, combination of western medicine with blood-activating and stasis-resolving was very commonly, especially antiplatelet drugs and nitrates drugs.
CONCLUSIONWestern medicine in the treatment of patients with CHD was in accordance with the guidelines recommend, but with the lower utilization rate. Traditional Chinese medicine has become an important method for the treatment of CHD, promoting blood circulation and removing blood stasis is an important part of traditional Chinese medicine treatment in patients with CHD.

AIM: To measure the macular thickness of normal young people by 3D 1000 optical coherence tomography (OCT) and study the repeatability of measuring results and the relationship between the thicknesses of macular and gender. At the same time, to compare our result with the data of other types of OCT, and to understand the consistency of the measuring results of macular thickness of different types of OCT.
METHODS: Totally 222 eyes in 111 young people were detected using 3D scan mode of Topcon 3D OCT 1000 (ver 2.4 ) . Twelve cases ( 24 eyes ) underwent repeatability check. We took transverse comparison between our measured results with other research's results.
RESULTS: There were 111 cases of young people, whose age were from 18-27 years old, all uncorrected and corrected visual acuity were≥1. 0, all intraocular pressure were <21mmHg. The average thickness of all macular region was 273. 32±17.08μm. Retinal volume of macular area was 7. 73 ± 0.37mm3 . Center thickness was 161 -264μm, and the average thickness was 200. 13±18. 81μm. Central macular thickness were 188 - 273μm, and the average thickness was 229. 00 ± 18. 20μm. The central macular thickness in men was significantly greater than that in women, and there was statistical difference. The results of repeated check of 12 cases ( 24 eyes ) in the macular area were no statistical difference except the outer ring of nasal quadrant, and the repeatability of average thickness in central macular thickness was better than in center thickness.
CONCLUSION:The repeatability of macular examination is good. The central macular thickness can be better repeated than the center thickness. The central macular thickness is 229. 00±18. 20μm in young people, according to the 3D 1000 OCT measurements. There are statistical difference of central macular thickness between different genders.

Objective To explore whether the change of S phase kinase-associated protein 2 (Skp2) expression could regulate mesangial cell proliferation. Methods Skp2 siRNA and control siRNA, pIRES-GFP-Skp2 plasmid and pIRES-GFP plasmid were designed and synthesized. Cell transfection was performed by Lipofectamine 2000. Skp2 mRNA and protein levels were detected by semiquantitative PCR and Western blotting respectively. Primary culture rat mesangial cells were divided into 6 groups: 0%FCS, 20%FCS, 10%FCS+pIRES-GFP plasmid, 10%FCS+pIRES-GFP-Skp2 plasmid, 20%FCS+control siRNA, 20%FCS+Skp2 siRNA. Cell number was detected by MTT. S phase entry was measured by BrdU labeling. Cell cycle profile was determined by flow cytometric analysis. Results Skp2 mRNA level was significantly down-regulated by Skp2 siRNA compared to control siRNA. Skp2 protein level increased after pIRES-GFP-Skp2plasmid transfection compared to pIRES-GFP plasmid. MTT, BrdU labeling and cell cycle profile demonstrated that cell number (A: 0.419±0.088 vs 0.305±0.036, P<0.01) and S-phase cells (BrdU labeling positive cell: 0.21±0.04 vs 0.15±0.03, P<0.01;S-phase cell number:20.18±0.64vs 14.33±0.37, P<0.01) obviously increased after Skp2 plasmid transfection, while decreased after Skp2 siRNA transfection compared to control groups (A: 0.328±0.069 vs 0.482±0.133, P<0.01;BrdU labeling positive cell: 0.17±0.01 vs 0.24±0.00, P<0.01; S-phase cell number: 16.52±0.75vs 23.81 ±1.25, P<0.01). Conclusion Over-expression of Skp2 stimulates mesangial cell proliferation while down-regulated expression of Skp2 inhibits mesangial cell proliferation.

A study on the microbial transformation of glycyrrhetinic acid (GA) was conducted by a fungus, Cunninghamella blakesleeana CGMCC 3.970 systematically. After incubation with the cell cultures of C. blakesleeana CGMCC 3.970 at 25 degrees C for 7 days on a rotary shaker operating at 135 r x min(-1), GA was converted into one major product and five minor products. The products were extracted and purified by solvent extraction, macroporous adsorbent resin, silica gel column chromatography, and semi-preparative RP-HPLC chromatography. Their structures were identified as 3-oxo-15α-hydroxy-18β-glycyrrhetinic acid(1), 3-oxo-15β-hydroxy-18β-glycyrrhetinic acid (2), 7β,15α-dihydroxy-18β-glycyrrhetinic acid (3), 3-oxo-7β, 15α-dihydroxy-18β-glycyrrhetinic acid (4), 7β-hydroxy-18β-glycyrrhetinic acid(5) and 15α-hydroxy-18β-glycyrrhetinic acid(6) by the analyses of MS, 1H-NMR and 13C-NMR spectroscopic data respectively. Among them, 2 was a new compound. These results suggest that C. blakesleeana CGMCC 3.970 has the capability of selective ketonization and hydroxylation for GA.
