It was found that the Lao Shan polsaccharide P, one of the chemical components of polystictus versicolor increased the number of acetylated low density lipoprotein ( acLDL ) receptorsin the macrophages and stimulated the binding, internalization and degradation of (125I ) acLDL by the macrophages in vitro. The effect on cell degradation of ( 125I ) acLDL was dose-effect. At 100?g/ ml of the Lao Shan polysaccharide P, the effect was maximum and the degradation of ( 125I ) acLDL increased 77% ( P

Objective To introduce the technique of three dimensional portal venography of multi detector row spiral CT and its clinical application in the evaluation of the portosystemic collateral shunts of liver cirrhosis. Methods All relevant literatures were retrospectively reviewed on the application of two dimensional and three dimensional reconstruction techniques such as MIP, SSD, VRT of multi detector row spiral CT to demonstrate the collateral vessels of liver cirrhosis.Results The distribution, pathway and anatomy of portosystemic collateral vessels were well shown by multi detector row spiral CT portal venography. Conclusion Multi detector row spiral CT portal venography provides excellent depiction of the anatomic characteristics of the collateral shunts and enables the continuous tracing of vascular structures, thus it is very helpful in the imaging evaluation of the collateral vessels of liver cirrhosis.

The paper analyzed the compensation mechanism applied in public hospitals in different localities in China,which are currently experimenting with the zero price margin for drugs.It also introduced the revenue variations resulting from this practice.It is discovered that public hospitals can hardly make their ends meet with merely governmental financial input,and that lowered income of doctors and price distortion arc evident in those experimental hospitals,with little progress in overcoming the subsidization of medical services with drug sales.The authors recommended a comprehensive reform,the mechanism of diversified health input,change of internal incentive mechanism within the hospital,improvement in the healthcare service pricing mechanism,and exploration of new operation mechanisms for public hospitals.

Stasis is the critical causative factor and pathological production considered in clinic treatment. Promoting the circulation in blood vessel and removing stasis are equally important in treatment. Stasis is interactive with qi and blood. Removing stasis aims to regulating the circulation of qi and blood. Scraping therapy is one of the major approaches to stasis removal in TCM. In clinical practice, the stasis can be removed with scraping, bleeding and cupping, etc. Additionally, removing stasis with scraping should be combined with regulating qi and blood to enhance the therapeutic effect.

Objective To introduce the new nomenclature scheme of the International Working Group (1995) on hepatic nodules, and summarize the imaging features of various hepatic nodules in light of their pathological characteristics, and evaluate the diagnostic values of various imaging facilities.Methods Ultrasound, computed tomography(CT), magnetic resonance imaging(MRI), and angiographic CT were reviewed and introduced.Results Many of these types of hepatic nodules play a role in the de novo and stepwise carcinogenesis of hepatocellular carcinoma(HCC) in the following steps: regenerative nodule, low grade dysplastic nodule, high grade dysplastic nodule, small HCC, and large HCC. Accompanying such transformations, there are significant alterations in the blood supply and perfusion of these hepatic nodules.Conclusion Modern state of the art medical imaging facilities can not only delineate and depict these hepatic nodules, but also provide important clues for the characterization of focal hepatic lesions in most cases, thus facilitating the early detection, diagnosis and management of HCC in its early stage.

The researches of air cleaning functional coatings in pathogenic microorganism and chemical gaseous pollutants removal and indoor micro-environment improvement were reviewed.The mechanism of air cleaning was discussed.It is pointed out that the evaluation method is essential for the coatings development.

Objective To investigate the clinical significance of routine application of choledochoscope during operation of biliary duct.Methods The clinical data of 136 patients with the routine application of intraoperative choledochoscope dealing with bile duct diseases in this hospital from October 2003 to July 2009 were analyzed and summarized.Results Intraoperative choledochoscope inspection,taking stones and targeted surgery were performed in 116 cases with extrahepatic and (or) intrahepatic bile duct stones.The taking out rate of extrahepatic bile duct stones was 100% (85/85),the residual stone rates of extrahepatic and intrahepatic bile duct were 0 (0/85) and 22.6% (7/31),respectively,with the total residual stone rate was 6.0% (7/116).By using intraoperative choledochoscope,benign intrahepatic bile duct stricture was found in 13 cases,malignant extrahepatic and intrahepatic bile duct stricture in 8 cases.Four cases of hilar cholangiocarcinoma and 4 cases of common bile duct cancer,2 cases of lower segment of common bile duct polyp,3 cases of hepatolithiasis with the left hepatic bile duct carcinoma were diagnosed by biopsy via choledochoscope.Causes were confirmed by applying choledochoscope in 16 patients with obstructive jaundice.The use of choledochoscope with surgical treatment enabled benign and malignant bile duct stricture to achieve good results,without serious complications such as bile duct dilaceration,subphrenic abscess or acute cholangitis.Conclusions Using choledochoscope can tremendously reduce the residual rate of stone in biliary duct surgery,increase the definite diagnosis rate of biliary duct diseases and play a role of reasonable instruction in its treatment options.It has unique advantages in identifying causes of jaundice.It is remarkable that the role of applying choledochoscope to diagnose and cure biliary duct diseases.It should be widely used.

Objective:To investigate the regional cerebral blood oxygenation changes of left prefrontal lobe during dyslexic children recognizing Chinese characters. Methods:We use functional near-infrared imaging (fNIRI) technique to observe 28 dyslexic elementary school students and 19 healthy students who are not reading-impaired.Results:With fNIRI, significant activations were observed in the left prefrontal cortex of both dyslexic children and non-dyslexic children during primary processing of Chinese characters, and children with dyslexia were evoked more significantly ( P

How to select endocrine agents for patients with ER-positive/ Her-2 -positive breast cancer has been a difficult question. Increasing evidences shows a consistent results that an association between Her-2 overexpression and poor response of endocrine treatment, tamoxifen and the third generation aromatase inhibitors has the similar poor efficacy. The treatment strategy for such patients should prefer chemotherapy alone or in combination with trastuzumab, and endocrine therapy combining with trastuzumab may be the development strategy.

Gemcitabine is important pyrimidine antimetabolites drug. Ribonucleotide reductase is oneof its targets whose overexpression has been observed in several gemcitabine- resistant cell lines. Meanwhile,the NSCLC patients with high RRM1 expression levels have a relatively poor survival when treated with gem-citabine. To this day, the relationship between RRM1 expression levels in peripheral blood mononuclear cellsand gemcitabine is still uncertain and it deserves further research.
