Objective To understand the effect of vanadium to liver ultramicro structure in SD rats.Methods One hundred and fifty generaMevel SD rats of 2 months were randomly divided into control groups,30 in each,the males and females were equivalent,treated with ammonium metavanadate at doses of 0,10,20,40,60 mg/L through drinking water.After 2,6 and 10 weeks of treatment,6 rats from each group were weighed and the changes of ultramicro-structure in the liver were examined with electron microscope.Results As the increasing of dose,the increase in body weight showed a downward trend,but the coefficient of liver showed a increasing trend,the consistent performance was seen in male and female rat.After two weeks of exposure,the rats acted,ate and drank less,hair roughing and no shining,often getting together were seen.After 10 weeks,the rats had not the basic activities,the hair was disheveled and loose,some died,the structure of mitochondria and endoplasmic reticulum was normal in the 10,20,40 mg/L group,the number of endoplasmic reticulum increased,in 60 mg/L group,the rough endoplasmic reticulum vanished,the liver cytoplasm had a swelling phenomenon,the mitochondria reduced.Conclusion Vanadium have little effect on the liver cells of rats in low exposure level,but high level exposure may damage the liver cells in rats.

Drug therapy is one of the efficient methods for prostate cancer treatment. However, drug resistance greatly hindered the treatment of prostate cancer patients. Herein, the mechanisms of drug resistance in prostate cancer have been exhaustively reviewed, and that can provide an alternative strategy and new targets for anti-prostate cancer therapy.

Objective To evaluate the nutritional status of iodine of pregnant and lactating women in coastal and inland areas of Zhejiang province,and to provide scientific basis for iodine supplementation.Methods In 2009,five coastal cities,five coastal counties and three inland areas from Zhejiang province were selected by the cluster sampling method,and one sub-district(township) was randomly selected in each city (county),then one community (village) was randomly selected in each sub-district (township).Thirty pregnant women,thirty lactating women and fifty children aged 8 - 10,were randomly selected in each community(village) as the investigation objects to collect instant urine samples to detect urine iodine,and to collect thirty resident edible salt and some water samples to detect salt iodine and water iodine,if the numbers of water source were more than 5 then 1 water sample was collected by their location of east,south,west,north and center in each community(village),otherwise,the numbers of water samples collected were equal to the number of community (village).Results The medians of salt iodine of coastal city,coastal county and inland area were 28.42,25.29,and 33.24 mg/kg,respectively,and the medians of water iodine correspondingly were 5.41,11.52,and 2.80 μg/L,respectively.The medians of urinary iodine of pregnant and lactating women in Zhejiang province were 148.72 and 161.34 μg/L,respectively,which were less than that of children aged 8 - 10(231.02 μg/L,Z =8.57,8.24,all P < 0.017).The medians of urinary iodine in pregnant women from different areas were ranked in order as inland areas(211.42 μg/L),coastal counties (150.51 μg/L) and coastal cities (123.33 μg/L,Z =2.80,5.31,2.42,all P < 0.017),and in lactating women,the medians of urinary iodine in inland areas( 197.43 μg/L) was higher than that in coastal cities( 139.64 μg/L,Z =4.03,P < 0.017).Conclusions The overall levels of iodine nutrition in lactating and pregnant women in Zhejiang province are in the appropriate level,but that of the pregnant women in the coastal cities is inadequate.

One new neolignan identified as 2, 3-( trans) -dihydro-2-(4-hydroxy-3-methoxyphenyl) -3-[(beta-D-glucopyranosyloxy) methyl]-7-methoxybenzofuran-5-propenoic acid (1) and five known steroidal glycosides namely torvoside A(2), torvoside C(3), torvoside H(4), solanolactoside A (5), (25S)-6alpha-hydroxy-5alpha-spirostan-3-one-6-0-[alpha-L-rhamnopyranosyl-(1-->3-beta3)-beta-D-D-quinovopyr-anoside] (6) were isolated from the fruits of Solanum torvum. Their structures were elucidated on the basis of 1D, 2D NMR and MS spectroscopic analysis.

OBJECTIVETo evaluate the clinical effects of iliolumbar fixation for the sacrum fractures of Denis type II.
METHODSThe clinical data of 86 patients with sacrum fracture of Denis type II treated by iliolumbar fixation from January 2008 to January 2012 were retrospectively analyzed. There were 55 males and 31 females, aged from 17 to 55 years old with an average of 39.1 years. Among them, 73 cases complicated with pelvis fracture and 13 cases with acetabular fracture; 37 cases with sacral neurological symptoms and 49 cases without sacral neurological symptoms. Fracture healing time, nerve function, clinical function and complications were observed in the patients.
RESULTSIn 86 cases, 6 cases were out of followed-up and 80 cases were followed up from 24 to 71 months with an average of 36 months. The mean fracture healing time was 13 weeks (ranged, 10 to 38 weeks). According to Gibbons scoring to evaluate the neurological function, preoperative nerve rehabilitation, lower limbs feeling, lower limbs activity,bladder and rectum function,total score respectively were 0.62 +/- 0.04, 1.54 +/- 0.35, 1.12 +/- 0.18, 0.23 +/- 0.01, 3.46 +/- 0.47 and postoperative respectively were 0.82 +/- 0.12, 0.36 +/- 0.04, 0.05 +/- 0.01, 0.03 +/- 0.01, 1.25 +/- 0.22, there were statistically significant differences between preoperative and postoperative (P < 0.05). According to Majeed scoring to evaluate the clinical function, postoperative pain, standing, sitting, sexual life, work ability, total score respectively were 22.54 +/- 4.02, 27.93 +/- 5.46, 8.47 +/- 3.61, 2.54 +/- 1.33, 16.46 +/- 4.34, 81.32 +/- 8.73, 60 cases got excellent results, 17 good, 3 fair. The main complications including fracture nonunion of 5 cases,deep incision infection of 1 case, and screw prominence resulting uncomfortable of 8 cases.
CONCLUSIONIliolumbar fixation has the advantages of stable fixation, satisfactory functional rehabilitation, less complications, and is a good method in treating sacrum fracture of Denis type II.

The effects of surfactants on the production of cellulase by Trichoderma viride in liquid substrate fermentation process were investigated. Straw was used as the sole carbon source and the surfactants were biosurfactant rhamnolipid from Pseudomonas aeruginosa and Tween 80. The changes of FPA,CMCase,Avicelase and surface tension with time were analyzed under different concentrations of the two surfactants. The results showed that the surfactants can enhance the enzyme activity of Trichoderma viride. The FPA,CMCase,Avicelase were promoted 1.08,1.6 and 1.03 times higher than the controls by rhamnolipid. The enhancement of the enzyme activity by rhamnolipid was much higher than that of Tween 80. At the same time,rhamnolipid was not degraded prior to other substrate.
