Mental health investigation by way of questionnaires has been performed among postgraduates and doctors in Guangzhou university of traditional Chinese medicine (TCM) to reveal psychological puzzlements and demands of contemporary medical graduate students. We hope that the investigation results may be contributed to the plan of higher medical education, especially to mental health education.

Objective Investigate the compatible stabilities of Sodium Glucuronic Acid Injection and Ganlixin Injection.Methods The Sodium Glucuronic Acid Injection mixed with Ganlixin Injection,to study the content of Sodium Glucuronic Acid Injection and Ganlixin Injection in different time by uv spectrophotometry,Investigate the appearance of the mixed solution,detect PH values and Insoluble Particles.Results At experimental temperature(15℃),the mixed solution,PH values,Insoluble Particles and the relative percentage have no obvious change in 4 hours.Conclusions The Sodium Glucuronic Acid Injection mixed with Ganlixin Injection is stabilization,so Sodium Glucuronic Acid Injection can combined with Ganlixin Injection.

Objective To investigate the value of ultrasound in diagnosis of fetal simple unilateral multicystic dysplastic kidney (MCDK) disease.Methods Pregnant women who underwent prenatal ultrasound screening and follow-up were analyzed retrospectively,and 29 fetues with MCDK were found.After exclusion of pregnancy syndrome,other structural abnormalities and chromosomal abnormalities,15 fetues willing to continue pregnancy and accepting the follow-up tracking observation were observed to postpartum.Ipsilateral renal ultrasonographic characteristics,contralateral renal morphology and size,growth and development of children and the renal function were analyzed.Results The minimum follow-up time of the 15 fetus was pregnancy to 7 months after birth,the maximum follow-up time was pregnancy to 5 years of age in children.Ultrasound showed that ipsilateral kidney volume became large in fetal period,reduced gradually in late pregnancy,and atrophy in 5 6 months after birth,even could not displayed with untrasound.The shape,size,and sonographic characteristics of the healthy kidney were similar to the normal gestational age kidney.Prenatal fetal growth indicators and amniotic fluid volume were normal.After birth,except for 1 child with overweight,other children's growth and development indicators were almost normal.Conclusion Fetus with simple unilateral MCDK has a good prognosis.Ultrasound has important value in the examination and follow-up.It can provide reliable basis for prenatal diagnosis and consultation.

A rapid, reliable and sensitive pressurized capillary electrochromatography-Laser induced fluorescence ( pCEC/LIF ) method with trifluoroacetic acid ( TFA ) pre-column derivation for simultaneous determination of four aflatoxin ( AFB1 , AFB2 , AFG1 , AFG2 ) was developed. This method included separation on a capillary column packed with 1. 8μm C18 particles using 0. 05% FA aqueous solution/methanol (55:45, V/V) as mobile phase at a pump flow rate of 0. 05 mL/min when the split ratio was 1:300. Under the optimum conditions including running voltage of 15 kV, excitation wavelength of 375 nm and emission wavelength of 450 nm, the baseline separation of four aflatoxins was achieved within 10 minutes. The limits of detection (LODs) were 0. 02, 0. 016, 0. 008 and 0. 01 μg/L for AFG1, AFB1, AFG2, AFB2(S/N=3), respectively. The linear detection ranges of AFG1 , AFB1 , AFG2 , AFB2 were 0. 1-10, 0. 1-10, 0. 1-3 and 0. 1-3 μg/L with correlation coefficients (R2) of 0. 9999, 1. 0000, 0. 9995 and 0. 9997, respectively. The established method was applied to analyze the peanut butter, and the recoveries of standard addition experiment were between 90 . 0% and 112 . 0% for all analytes ( RSDs=0 . 5%-1 . 9%) .
