One of the hallmark features of children with autism is language barrier,which mainly manifested with lack of visual contact and attention,imitation speech,broad pronunciation problems,poor understanding abilities to speech and abstract questions,deficiency of logicality,spoken language disorder,confusion about the usage of pronouns such as you,I and she or he,etc.According to the basic principles of language training,visual perception tracing,vision contact,cultivation of communication desire,auditory and understanding training can all be used to make children with autism to understand the relationship between pronunciation and words,try to pronounce syllables,make good preparation for valid pronunciation in the early stage of language training.Respiration training,point massage of oral surface and valid usage of pronunciation organs' practice can help them to say phrase and simple sentences gradually.They can say a sentence correctly and achieve the destination of grasping language through learning decorative words and enhancement of understanding and logic abilities.Very efficient result could be approached through correct evaluation,found existing problems and using correct training methods during language training of children with autism.

Objective To evaluate the effects of therapy with small volume of different fluids on renal blood flow in endotoxemia rats.Methods Thirty parthogen-free SD rats weighing 180-250 g were randomly divided into 5 groups (n = 6 each):group Ⅰ control; group Ⅱ LPS; group Ⅲ LPS + 7.5 % hypertonic saline (HS);group Ⅳ LPS + hydrozyethly starch (HES) 130/0.4 and groupⅤ LPS + hypertonic saline plus hydroxyethly starch (HS-HES) 40. The animals were anesthetized with intraperitoneal 3% pentobarbital 40 mg/kg. Left carotid artery was cannulated for BP and HR monitoring and fluid administration. In groupⅡ-Ⅴ LPS 1 mg/kg was administered via arterial cannula. In group Ⅲ, Ⅳ and V 4 ml/kg of 7.5% HS, HES 130/0.4 AND HS-HES 40 were administered via arterial cannula respectively at 30 min after LPS administration.In groupⅠ and Ⅱ normal saline 4 ml/kg was given insteadt. Renal blood flow was measured with Doppler ultrasound before LPS (T1 ,baseline), at 30 min after LPS (T2), 10, 30 and 60 min after fluid therapy (T3, T4, T5). The animals were then sacrificed and both kidneys were removed for microscopic examination with light microscope. Results Renal blood flow was significantly decreased and was significantly recovered to some extent by therapy with different fluids especially with HS-HES 40 in group Ⅴ. Conclusion Therapy with small volume of HS,HES or HS-HES could increase renal blood flow and inprove renal microcirculation especially HS-HES.

A new UPLC method was developed for the simultaneous determination of eleven characteristic flavonoid glycosides in Ginkgo biloba leaves. The natural occurrence of flavonoid glycosides in Ginkgo biloba leaves within one vegetative season was investigated for the first time. The analysis was performed on an Agilent ZORBAX Eclipse Plus C18 column (50 mm x 4.6 mm, 1.8 microm), the mobile phase A was acetonitrile, the mobile phase B was 0.4% phosphate aqueous solution in a gradient elution at a flow rate of 0.6 mL x min(-1), the detection was carried out at 360 nm. The result showed that eleven flavonoid glycosides had good linearity with good average recovery, separately. The method was proved to be accurate, rapid and good reproducible for the quality evaluation of Ginkgo biloba leaves, and provide an easy and rapid means for the quantitative analysis of flavonoid glycosides and their content fluctuation with seasons.

The relationship between the hepatic ischemia/reperfusion (I/R) injury and the balance of nitric oxide/endothelins (NO/ET) was studied. The changes of the ratio of NO/ET and the hepatic injury were observed in a rat hepatic I/R model pretreated with several tool drugs. In the acute phase of hepatic I/R injury, the ratio of plasma NO/ET was reduced from 1.58 +/- 0.20 to 0.29 +/- 0.05 (P < 0.01) and the hepatic damage deteriorated. NO donor L-Arg and ET receptor antagonist TAK-044 could alleviate the hepatic I/R injury to some degree, whereas NO synthase inhibitor L-NAME aggravated the damage. It was concluded that the hepatic I/R injury might be related with the disturbance of the NO/ET balance. Regulation of this balance might have an effect on the I/R injury.

Whether M3 cholinergic receptor signal transduction pathway is involved in regulation of the activation of NF-kappaB and the expression of chemokine MOB-1, MCP-lgenes in pancreatic acinar cells was investigated. Rat pancreatic acinar cells were isolated, cultured and treated with carbachol, atropine and PDTC in vitro. The MOB-1 and MCP-1 mRNA expression was detected by using RT-PCR. The activation of NF-kappaB was monitored by using electrophoretic mobility shift assay. The results showed that as compared with control group, M3 cholinergic receptor agonist (10(-3) mol/L, 10(-4) mol/L carbachol) could induce a concentration-dependent and time-dependent increase in the expression of MOB-1, MCP-1 mRNA in pancreatic acinar cells. After treatment with 10(-3) mol/L carbachol for 2 h, the expression of MOB-1, MCP-1 mRNA was strongest. The activity of NF-kappaB in pancreatic acinar cells was significantly increased (P<0.01) after treated with M3 cholinergic receptor agonist (10(-3) mol/L carbachol) in vitro for 30 min. Either M3 cholinergic receptor antagonist (10(-5) mol/L atropine) or NF-kappaB inhibitor (10(-2) mol/L PDTC) could obviously inhibit the activation of NF-kappaB and the chemokine MOB-1, MCP-1 mRNA expression induced by carbachol (P<0.05). This inhibitory effect was significantly increased by atropine plus PDTC (P<0.01). The results of these studies indicated that M3 cholinergic receptor signal transduction pathway was likely involved in regulation of the expression of chemokine MOB-1 and MCP-lgenes in pancreatic acinar cells in vitro through the activation of NF-kappaB.

Objective To assess the relationship between fat metabolic parameters and androgen concentration in the cord blood of newborns of mothers with polycystic ovary syndrome (PCOS). Methods This cross-sectional study included PCOS women (n=55) and neonatal, and 40 cases with matched body mass index (BMI) were used as control. The clinical data including height, body mass, waist circumference, hip circumference of PCOS group, and length and head circumference in newborns after delivery were measured and compared. Blood lipid level, serum insulin and testosterone level were detected using umbilical artery-vein mixed cord blood after delivery. Regression analysis was used to analyze the influence factors of neonatal cholesterol and testosterone levels. Results The neonatal birth weight, head circumference, cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol and triglyceride level were significantly lower, birth height and testosterone level were significantly higher, in PCOS group than those of control group (P＜0.05). Values of waist to hip ratio, BMI, cholesterol, high density lipoprotein cholesterol and testosterone levels were significantly higher in PCOS group than those of control group (P＜0.05). The insulin, cholesterol and triglyceride levels of PCOS mother were risk factors for neonatal cholesterol level(P ＜ 0.05). The cholesterol, triglyceride and free testosterone levels of PCOS mother were risk factors for increased neonatal free testosterone (P ＜ 0.05). Conclusion Mother with PCOS may affect fetal birth weight, head circumference and cord blood lipid metabolism, which may be related with the elevated level of testosterone during the fetal period.
