Objective To observe and analyze the four changes of plasma D- dimer and coagulation in pregnant women at different stages of pregnancy, and to explore the value of the test. Methods The subjects of this study were 120 pregnant women who underwent routine physical examination in our hospital, according to different stages of pregnancy (early pregnancy, middle pregnancy, late pregnancy, and before delivery) Four D- dimer and four blood coagulation tests were performed in pregnant women, and the results were observed and compared. Results During the pregnancy, D- dimer has increase trend (P<0.05); early in pregnancy, pregnancy and late pregnancy, PT has shortened(P<0.05); pregnancy, APTT has shortened (P<0.05), at the end of pregnancy and parturient period, showing a significant shortening (P<0.05); phenomenon in early pregnancy to mid pregnancy stage, FIB increased significantly (P<0.05), and at the end of pregnancy to perinatal period, with a sharp increase (P<0.05). Conclusion It is of great significance to perform dynamic monitoring of of plasma D- dimer and coagulation four indices in pregnant women during pregnancy.

To investigate the mechanism of lead biosorption and biotransformation in lead-resistant bacteria in microcosmic scale, synchrotron radiation micro X-ray fluorescence (μ-SRXRF ) and X-ray absorption near edge structure ( XANES) was used to determine the element distribution characteristics and speciation of lead ( Pb) in lead-resistant bacteria strain isolated from farmland soil samples taken from a lead-zinc mine in Lanping county, Yunnan province in China. The isolated species was identified to be Arthrobacter sp. The concentration of Pb biosorpted in lead-resistant bacteria was directly determined byμ-SRXRF, and the results showed that the highest concentration was 5925μg/g and the bioaccumulate factor was 14 . 8 . Speciation of Pb in lead-resistant bacteria B2, LB ( Lysogeny Broth) medium and soil were also presented after using Pb LⅢXANES. Compared with Pb LⅢ XANES peak shape and peak position between standard samples, it was demonstrated that the Pb in lead-resistant bacteria was mainly formed by amorphous forms like PbS (58. 0%), (C17H35COO)2Pb (22. 2%), Pb5(PO4)3Cl (19. 8%) rather than organic Pb speciation which was exist in LB medium. Therefore, the isolated lead-resistant bacteria could biotransform Pb to sulfuric compounds. The biotransformation regular could be of great interest for other investigators as reference in study of bioavailability impact factor of heavy metals.

0.05)in cell volume between the experimental group and control group after exposured in hypertonic NaCl saline for 15 minutes. Compared with the control level,after 60 minutes and 1 day all astrocytes shrunk significantly, (P0.05). Conclusion:Astrocytes can restore their cell volume following exposition in hypertonic saline.

0.05). The cell volume of astrocytes was not significantly changed after exposition to hypertonic-hyperoncotic solution for 15 minutes. After 60 minutes all astrocytes shrunk significantly until 1 day later. 7 days later,their volumes restored to the value in control group. Conclusion: The hippocampal neuroncs have not the autoregulative ability of the cellular volume. but astrocytes have after exposition to hypertonic-hyperoncotic solution for 15 min: the volume of both cells 7 days later can restore to the previous value.

Intracerebral vessels from 10 hemispheres of children were perfused with ABS and observed under the 6212-Ⅲ surgical microscope and TSM-Ⅰ scanning electron microscope.1. The arterial network of the pia mater shows irregular anastomoses. Many terminal branches in the meshwork do not form anastomosis but perforate into the brain tissue at right angle. Most of the points where the arteries perforate are longit udinally arranged along the gyri.2. The venous network of the pia mater usually lies deeper than the arteries and becomes superficial to the latter after joining together to form larger vessels.3. The cortical arteries have an average diameter of 44.3?m. They are densely distributed like hairs of a brush.4. The tributaries of the cortical veins join to form larger veins assuming the shape of an inverted fir tree.5. The medullary arteries are different in length and in diameter. The diameter averages 158.2?m. The arteries perforating through the top of the gyrus are straight but those from the sulcus bend to a certain degree after they pass through the cortex. Branches from the middle segments come out vertically and form "T"-shape branches. The deep segments send out branches like the roots of a tree and form widespread anastomoses with the central arteries. Wavy, tortuous medullary arteries can be also found. The casts of these arteries were observed under the SEM.The medullary veins and central arteries have been studied and described microanatomically.

Chinese medicine (CM) develops with the survival, reproduction, growth, and progressing of the Chinese nation. Scientific technologies not only promote continual progressing of human societies, but also provide new ideas and methods for the development of CM. In recent years, great changes have taken place in CM complying with developing modern scientific technologies, mainly manifested in the depth of CM theories at molecular levels, the combination of syndrome differentiation and disease identification, continuous innovation and development of clinical diagnosis and treatment techniques, diversified dosages of Chinese materia medica, the academic tendency of education patterns, occupational refinement, diversified medical practice modes, and so on.

Tu-Jia medicine is an important part of traditional Chinese medicine (TCM).“San-Yuan doctrine”is the guiding ideology of Tu-Jia medicine, but there is no systematic exposition of its literature origin. This paper ar-gued that“San-Yuan doctrine”of Tu-Jia medicine was originated in the“San-Yuan”of Taoism. Its formation was closely related to the impact of Taoism and Tu-Jia culture, the understanding of human physiology and pathology in Tu-Jia medicine. This paper expounded the origin of“San-Yuan doctrine”, the guiding ideology of Tu-Jia medi-cine and Taoism culture through citing a number of theoretical bases. First of all, the concept of“San-Yuan”in Tu-Jia medicine originated in Taoism. Secondly, legends about the Lord Lao-Zi and Medicine King Bodhisattva in Tu-Jia medicine were closely related with Taoism. Moreover, there existed important links between Tu-Jia medicine and Taoist medicine. For example, both of them are aware of the importance of brain. The reason, I think, is firstly due to the penetration of Taoism in Tu-Jia culture. Taoism culture has a profound influence on Tu-Jia culture. Sec-ondly, the understanding of human physiology and disease in Tu-Jia medicine is closely related to“three”. There-fore, Tu-Jia medicine took“San-Yuan doctrine”as its own guiding ideology. It is of great significance to the study of ethnic minority medicine culture and inheriting its academic thoughts by the study of Tu-Jia medicine origin.

Objective To investigate whether the effect of pioglitazone on TNF-α-induced insulin resistance is associated with altering IRS-1-induced signaling. Methods 3T3-L1 adipocytes were treated with TNF-α for 24 hours with or without being pretreated with 10μM piglitazone for 6 hours or with pioglitazone alone.Insulin-stimulated glucose uptake of 3T3 adipocytes was measured by using 2-deoxy 3H glucose.The Western blot was used to measure IRS-1, PKB, PKC-λ protein and tyrosine phosphorylation on IRS-1, PKB and PKC-λ phosphorylation. Results Both TNF-α and pioglitazone increased glucose uptake of 3T3 adipocytes under basal status.On TNF-α treated cells, insulin-stimulated glucose uptake was decreased by about 50%, accompanied with the reductions of IRS-1 protein level, tyrosine-phosphorylation of IRS-1 and PKB phosphorylation.TNF-α treatment had no effect on PKC-λ phosphorylation. Pioglitazone pretreatment was able to antagonize TNF-α-induced insulin resistance in 3T3 adipocytes partly reverse IRS-1 protein, increase insulin-stimulated tyrosine phosphorylation of IRS-1,and increase phosphorylations of PKB and PKCλ. Conclusion TNF-α-induced insulin resistance in 3T3-L1 adipocytes is related to impaired tyrosine phosphorylation of IRS-1. Pioglitazone antagonizes the above TNF-α induced insulin resistance.

Objective To compare the features of cerebral palsy with pachygyria or periventricular leukomalacia (PVL). Methods 15 children with pachygyria and 35 children with PVL were included. Their diagnosed age, clinical subtype, complications, Gross Motor Func-tion Classification System (GMFCS) were compared. Results The diagnosed age was significantly younger (P<0.001), the GMFCS was lower (P<0.05), the incidence rate of epilepsy was higher (P<0.05), and the intelligence was significantly lower (P<0.001) in the pachygyria group than in the PVL group. Conclusion Cerebral palsy children with pachygyria develope worse than that with PVL, as well as their prog-nosis.
