Traditional sequences of magnetic resonance imaging (MRI) such as T1-weighed imaging, T2-weighed imaging, and fluid-attenuated inversion recovery (FLAIR) imaging can sensitively detect the subacute and chronic intracranial hemorrhage; gradient echo sequence can detect various stages of intracranial hemorrhage, but there is no correlation between the signal intensity of the hematoma and the time of the presence of hematoma. Diffusion-weighted imaging and apparent diffusion coefficient may provide more information about the center and surrounding areas of hematoma, as well as the hemorrhagic tendency after infarction.

Background The extraocular muscles (EOMs) Pulley in primate is related to the function of EOMs,but there are arguments about that.The location of rabbit's eyes is different from the primate.Study on the structure of the extraocular muscle connective tissue in rabbit may play a role to analyze the function of the EOMs Pulley.Objective The structure of the connective tissue around EOMs in rabbit was studied,the difference between this structure in rabbit and homan' s EOMs Pulley in past reports was analyzed,and then,the role of EOMs Pulley to ocular movement was investigated.Methods Five adult rabbits were involved.The gross anatomy of an orbit in each rabbit was observed.The other orbit was processed with paraffin imbedding and coronal serial sections.A murine monocolonal antibody to α-smooth muscle actin(α-SMA) was used to show the smooth muscle,while Weigert stain was used to show muscle and collagen,and Masson trichrome stain to show the elastin.Results An encircling ring of collagen circled every EOM.The collagen ring was thin and connected to the orbital layer muscle fiber loosely.Collagen tissues coupled to adjacent EOMs.Less elastin fibers and scanty the smooth muscle cells were embedded in the collagen.Conclusions The connective tissue around rectus in rabbit is different from that in human with developed binocular ocular movements.It shows that connective tissue around EOMs may be related to the function of ocular movements.

Based on the survey of the learning preference of Kunming Medical College students,we analyze relationship between students’learning style and personalities.In order to match different learning style,teachers must find some strategies in their English teaching.

OBJECTIVE:To establish capillary GC method for the determination of residual organic solvents in artesunate,such as methanol and ethyl acetate.METHODS:Capillary GC was adopted and the temperature of flame ionization detector was 250℃.RESULTS:The linear range were 0.03～0.605 mg?mL-1 for methanol(r=0.999 8) and 0.05～1.002 mg?mL-1 for ethyl acetate(r=0.999 7).The average recovery rates were 98.7% for methanol(RSD=3.0%) and 99.1% for ethyl acetate(RSD=2.1%).Only the ethyl acetate was detected in samples.CONCLUSION:Established method is simple and accurate for the content determination of residual organic solvents in artesunate.

Hepatic artery stricture (HAS) after liver transplantation can lead directly to transplanted liver function exhaustion and complications of biliary system. The early diagnosis and treatment are crucial for better prognosis. Doppler ultrasound is the first method of choice, and angiography can give further clear dignosis. The balloon dilatation is still effective for hepatic arterial stenosis. With the more adaptable usage of oronary stent, if possible, would reveal more promising result especially for tortuous stenotic hepatic artery. The vascular reconstruction or repeated liver transplantation is still the effective therapeutic methods.

BACKGROUND: Tissue engineering provides a new way for the repair of urinary tissue and organ defects.Urinary tissue engineering has shown a bright prospect.OBJECTIVE: To review the latest research on urinary tissue engineering at national and international level.METHODS: With the keywords of tissue engineering, urology, scaffold, vascularization in Chinese and in English,respectively, a computer-based search for articles published from January 2000 to January 2016 was performed in CNKI and PubMed databases. The articles addressing urology tissue engineering, scaffolds and vascularization were collected,summarized and analyzed.RESULTS AND CONCLUSION: The selection and cultivation of seed cells, scaffold material performance, tissue construction in vitro, and degree of vascularization all make an important influence on the repair of urinary injuries. As different seed cells hold different biological characteristics, we should make full consideration prior to choosing an appropriate seed cell, so as to pave a good foundation for urinary tissue engineering. Scaffolds with good three-dimensional structure can promote the cell growth and proliferation, tissue in-growth and vascularization.Tissue-engineered materials are superior to traditional repair materials, but still on initial stage, and further large scale trials will be necessary. Moreover, some problems needed to be solved, such as the regenerated tissue with incomplete function different from natural tissues, and regeneration failure caused by biological stent rejection.

Object To study the difference of phenylethanoid glycoside between the cultured cells of Cistanche salsa (C. A. Mey.) Benth. et Hook. f. and Herba Cistanche. Methods Making comparison by means of FTIR and HPLC technique. Results Using the FTIR technique, the infrared spectrum of cutured cell of C. salsa was similar to that of native Herba Cistanche at a certain extent. The HPLC analysis indicated that the main chemical constituents in cultured cells of C. salsa were similar to that of native Herba Cistanche while considerable difference of constituents was found between them. Conclusion On the whole, there are much more constituents in the cultured cells of C. salsa comparing with the native Herba Cistanche. The content of echinacoside and acteoside in the cultured cells is much higher than that in the native Herba Cistanche.

Three bacteria of decomposing lecithin and 4 bacteria of dissolving aptite were incubated for 4 weeks with sand media respectively. Phosphorus in the sand was extracted with distilled water and measured by different methods. It was found that the bacteria have a quite different ability to release P from the materials. Part of the P released became organic phosphorus compounds in microbial tissue. However, a large amount of the P was reserved in microbial cells in a form of phosphates. The direct measurement of P in the extract by molybdenum blue method would underestimate the capacity of the bacteria to release P from the materials. The correct approach was that the sand was fumigated with chloroform and then digested with acid before the measurement by molybdenum blue method.
