Aim To study ethanol-induced changes in the development and neuronal number of visual cortex in C57BL /6 mice. Methods Female mice were fed with ethanol during pregnancy . The neuron density (ND) and cortical thickness (CT) in visual cortex of off spring mice were measured at either P0, P7 and P14 with hematoxylin and eosin (H.E) and Nissl staining. Results Embryonic death and malformationswere found in the ethanol-treated groups. Malformations, such as microcephaly,anencephaly and myeloschisis with spinabifida, etc were found in late-term embryos. The malformation rate was 12%. Compared with control group, the development of visual cortex in ethanol-treated groups was delayed, and its lamination was in disorder. The neuron polarity was disturbed. Neuron loss was found after ethanol exposure. At various ages, the neuron density in ethanol-treated groups was lower than that in control group(P

To study the effect of wearing overnight orthokeratology ( OK) contact lens on corneal topography and tears in adolescents.METHODS: The diopter, corneal curvature, corneal surface regularity index ( SRl ) , tear break - up time ( BUT ) , Schirmer l test, and corneal fluorescent ( FL ) were recordedon 40 (80 eyes) adolescent myopia patients (mean age 13. 68±2. 32 years), who had worn OK contact lensfor more than 1 year, with mean spherical equivalent refraction -3. 61 ± 1. 48D before wearing OK contact lens. These indexes were tested and recorded before the patients' wearing OK contact lens and 5 times (1wk and 1, 3, 6, 12mo after the first wearing) during the patients' overnight wearing OK contact lens for 8~10 hours per day.RESULTS: Compared with pre - wearing, at post -wearing OK contact lens 12mo, the mean spherical equivalent refraction was apparently decreased from -3.61±1. 48D to -1. 39±1. 31D(P<0. 01). The corneal curvature was significantly flattened from 42. 29 ± 1. 55D to 40.13±1. 41D (P<0. 01). Mean SRl was increased from 0. 34± 0. 01 to 0. 37 ± 0. 01 ( P<0. 01 ). Mean BUT was decreased from 10. 39±2. 25s to 7. 26±1. 77s (P<0. 01). These indexes were stable at 1wk after wearing OK contact lens overnight and had no significant differences during the following (1, 3, 6, 12mo after wearing) tests (P > 0. 05 ). There were no significant differences on Schirmer▏test during the 12mo of OK wearing(P>0. 05). The cases of corneal fluorescent staining increased were mainly grade l, and the number of corneal staining grade l at 1 wk and 1, 3, 6, 12 mo after wearing were 15 eyes (18. 8%), 9 eyes (11. 3%),13 eyes (16. 3%), 9 eyes (11. 3%), and 12 eyes (15. 0%). BUT of corneal staining grade l wasdecreased significantly, compared with the BUT of corneal staining grade 0 during the 12mo of OK wearing (P<0. 05). CONCLUSlON: OK contact lens can significantly decrease the degree of myopia and K value of corneal curvature without changing tear volume. However, tear film stability weakens, which needs regular follow-up.

Objective To explore the expression of tissue inhibitor of metalloproteinases-2(TIMP-2) in peripheral blood lymphocytes in patients with chronic obstructive pulmonary diseases(COPD) and the association of smoking and TIMP-2 mRNA. Methods The expression of TIMP-2 mRNA in peripheral blood lymphocytes was measured by reverse transcription-polymerase chain reaction(RT-PCR) in 44 patients with COPD and 42 healthy smokers.The correlation analysis was then conducted between TIMP-2 mRNA expression and smoking index. Results The expression of TIMP-2 mRNA was 0.753?0.154 and 1.170?0.196,respectively,in patients with COPD and healthy smokers(P

In order to investigate the influence of angiotensin II on hematopoietic system, CD34+ cells in cord blood were purified, and the effects of angiotensin II in combination with various cytokines on their growth and differentiation were studied by cell culture in vitro. It was found that angiotensin II in suspending medium could stimulate both BFU-E and CFU-GM expansion. The number of BFU-E and CFU-GM was increased with the increases of angiotensin II concentrations during a certain range. In addition, the expansion fold of CFU-GM was increased from 2.3 +/- 0.8 times to 7.8 +/- 2.3 times when angiotensin II was added in the presence of SCF+G-CSF+GM-CSF+IL3 cytokines mixture. Similarly, the expansion fold of BFU-E was increased from 3.1 +/- 1.8 times to 9. 2 +/- 2.3 times with angiotensin II in the presence of SCF+EPO+TPO+IL-3. In the semi-solid medium, angiotensin II could stimulate CFU-GM expansion but had no effect on the growth of BFU-E. In conclusion, angiotensin II had some stimulating effects on cord blood hematopoietic progenitors expansion in vitro in the presence of other cytokines.

Objective To study intermediate and long term efficacy of uterine arterial embolization (UAE)with sodium alginate microspheres(KMG)at diameters 500-700μm in treatment of diffuse adenomyosis.Methods Totally 40 patients with standard difluse adenomyosis were enrolled and treated with UAE.KMG at diameters 500-700 μm for vascular embolization were used to embolize the arteries.The degree of dysmenorrhea,amount of menorrhea and uterine volume,as well as the level of serum CA125,follicle stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2)were investigated before andafter UAE.Results The follow up rates were 100%(40/40),100%(40/40),80%(32/40),68%(27/40),58%(23/40)after uterine arterial UAE 12,24,36,48 and 60 months respectively.The early,intermediate and long-term effective rates were 90%(36/40),88%(28/32),83%(19/23).The degree of dysmenorrhea,the amount of menorrhea and the uterine volume,as well as serum CA125 all decreased significantly 3 mouths after UAE at varying degrees(P＜0.05).Compared with other follow-up time,thedegree of dysmenorrhea and the amount of menorrhea declined to their lowest point at 6 month after UAE (P＜0.01).Paralleled with the decrease of volume of uterine,serum CA125 also decreased significantly and reached the lowest level 12 months later compared with other follow-up times(P＜0.01).Even at the 12th month after UAE serum CA125was not normal and FSH,LH and E2 did not change all the times after UAE(P>0.05).No recurrence was found during the 60 months after UAE.Condusion KMG used in UAE at diameters 500-700 μm has good intermediate and long term effectiveness in treatment of diffuse adenomyosis with no side effects.

Objective To evaluate value of narrow band imaging(NBI) endoscopy for children with abdominal Henoch?Schonlein purpura ( HSP ) . Methods A total of 46 patients with abdominal HSP were enrolled into the observation group(NBI intervention) from November 2010 to February 2016.Diagnostic rates of white light and NBI endoscopy in abdominal HSP patients, IgA positive rates of targeted biopsies and severe complications were retrospectively analyzed. A total of 25 abdominal HSP patients with no NBI intervention admitted from 2007 to 2009 were randomly enrolled into control group. Data of the control group were compared with those of observation group. Results In observation group, the diagnostic rate under NBI was significantly higher than that under white?light endoscopy[91. 3%(42/46)VS 67. 4%(31/46),χ2=8. 02,P<0. 05]. IgA positive rates of targeted biopsies under NBI was significantly higher than that under white?light endoscopy [ 95. 7%( 88/92 ) VS 69. 6%( 64/92 ) ,χ2 = 21. 79, P<0. 05 ] . Three patients developed such serious complications as digestive hemorrhage as predicted. Compared with control group, abdominal pain and blood stool relief time (10. 96±5. 32 d VS 19. 68±4. 29 d,t=7. 50,P<0. 01), fasting time(10. 37±5. 42 d VS 8. 80± 3. 71 d,t=7. 73,P<0. 01), hospital stay (18. 80±7. 11 d VS 23. 12±4. 36 d, t=3. 16,P<0. 01), time of stool occult blood negative ( 11. 41 ± 6. 30 d VS 19. 12 ± 4. 09 d, t=6. 22, P<0. 01 ) in observation group were significantly shortened. Conclusion NBI endoscopy is valuable for improving the diagnostic accuracy and biopsy accuracy and complication prediction of abdominal Henoch?Schonlein purpura in children.
