The painless needle insertion technique, summarized by Professor WU Lian-zhong during his decades of acupuncture clinical practice is introduced in this article, which is characterized as soft, flexible, fast, plucking and activating antipathogenic qi. The Sancai (three layers) lifting and thrusting manipulation technique is adopted by Professor WU for getting the qi sensation. And features of 10 kinds of needling sensation such as soreness, numbness, heaviness, distension, pain, cold, hot, radiation, jumping and contracture are summarized. Finger force, amplitude, speed and time length are also taken as the basis of reinforcing and reducing manipulations. Moreover, examples are also given to explain the needling technique on some specific points which further embodies Professor WU's unique experiences and understandings on acupuncture.

Collateral circulation may be a potential therapeutic target for ischemic stroke.However,aiming at improving the treatment of collateral circulation,it has not yet got the reliable clinical validation now.Therefore,undergoing the study of collateral circulation first in the animal models of chronic cerebral hypoperfusion has important practical significance.This article reviews the methods of rat chronic cerebral hypoperfusion models,neurobehavioral evaluation,cerebral perfusion assessment,collateral circulation pathways,and the experimental research status of improving collateral circulation.

Objective To study material basis of Zhou's prescription, components of effective parts Ⅰ in Zhou's prescription was gualitative and quantitative analyzed. Methods The components of effective part Ⅰ was identified by test-tube reaction and qualitative TLC method, the content of saponins and flavones was quantitative analyzed. Results Total content of the saponins and flavone are 1.07% and 0.85% in Zhou's Prescription. The purity of saponins and flavones in effective parts Ⅰ are 37.4% and 29.7%. Conclusion The main components of effective part Ⅰ in Zhou's Prescription were flavones and saponins.

By analyzing the situation that large general hospitals face at present in their development and the background of reform in the system of overall responsibility by the attending physician in the hospital, the authors offer an account of the guiding ideology for large general hospitals to adopt the system of overall responsibility by the attending physician, the specific steps taken and the initial results attained. They also discuss the impact of the system of overall responsibility by the attending physician on the hospital from the perspectives of human resources, technological innovation, managerial system, and information system. The positive significance of the system of overall responsibility by the attending physician in the management of the hospital reform is also identified.

Objective To analyze the corneal flap thickness in laser in situ keratomileusis(LASIK) using Moria M2 microkeratome and to identify the related factors. Methods Sixty patients with LASIK were divided into two groups: M2 90 group,using the Moria M2 90 microkeratome,n=30;M2 110 group,using the Moria M2 110 microkeratome,n=30.All were performed on both eyes with the right one treated first.Subtraction pachymetry was used to measure corneal flap thickness which was analyzed statistically with the data including age,preoperative corneal diameter,curvature,corneal thickness and refraction. Results In the 30 patients of M2 90 group,the mean corneal flap thickness of right eye and left eyes were(128.03?12.03)?m(105~156 ?m) and(123.40?12.38) ?m(92~147 ?m),respectively,and the corneal flap thickness were statistically different between the right and left eyes(P

Objective Through comparision of HER2/neu status detected by immunohistoehemistry (IHC),fluorescence insitu hybridization(FISH)and chromogenic insitu hybridization(CISH),to explore the clinical significance of FISH and CISH on detecting gene status of HER2.Methods Sixty-four paraffinembedded breast samples whose pathological types were infiltrating ductal carcinomas were tested by IHC for HER2 protein overexpression and CISH,FISH for HER2 gene status.The rate of chromosome 17 polysomy was also analyzed.Results Among the cases of HER2 protein overexpression(+++)group,the concordant ratios of IHC and CISH.FISH detecting HER2/neu status were 100%.Among the cases of HER2 protein overexpression(++)group,the concordant ratios were 95.83%and 91.67%.Among the cases of HER2 protein overexpression(+/-)group,the concordant ratios were also 100%.One case in which FISH and CISH were performed yielded the different results.so the general coincident rate was 98.41%.The incidence of chromosome 17 polysomy Was 45.16%,45.83%and 11.11%in three IHC(+++,++,+/-)groups,and the total incidence was 40.62%.ConclusionIHC is a preliminary screening method;HER2 gene status detected by CISH and FISH have high concordant ratio,CISH is a more convenience and viable method to detect HER2/neu status,when doubling interference of fichromosome 17 polysomy,we need to select FISH further.

Objective To investigate the effect of pigment epithelium- derived factor (PEDF) on p38MAPK-CREB pathway and the expression of fibronectin (FN) in human mesangial cells (HMCs) cultured with high glucose. Methods HMCs were treated with different concentrations of glucose and the osmotic control respectively in the presence or absence of PEDF for 24 h:normal glucose (5.6 mmol/L),24.4 mmol/L mannitol,high glucose (30 mmol/L),high glucose+PEDF(30 mmol/L glucose with 10 nmol/L PEDF,40 nmol/L PEDF or 100 nmol/L PEDF).After samples were collected,the expression of phospho-p38MAPK (p-p38) and p-CREB was assessed by Western blotting,while FN mRNA and protein expression was assessed with RT-PCR and ELISA respectively. Results In contrast to normal glucose and mannitol treatments,the expression of p-p38MAPK,p-CREB and FN increased significantly in high glucose group (all P＜ 0.01).However,PEDF abolished the up-regulation of p-p38MAPK,p-CREB and FN induced by high glucose (all P＜0.05). Conclusion PEDF may inhibit fibrosis through P38MAPK-CREB pathway in diabetic nephropathy.

Insulin resistance model of 3T3-L1 adipocytes were prepared with plamotic acid.Adipocytes with generated insulin resistance were cultured with different concentrations of globular domain of adiponectin(gAd:250,500,1 000 ng/ml).The cell culture medium glucose content was detected with the glucose oxidase method,the mRNA expressions of insulin receptor substrate-1 (IRS-1),phosphatidylinositol-3 kinase(PI3K),and protein kinase B(PKB) were detected with real-time quantitative PCR method.The phosphorylation of IRS-1 was detected by Western blot.Compared with the control group,the experimental group showed significantly increased glucose consumption (P ＜ 0.01),and with the increasing gAd concentration,glucose consumption was gradually increasing.IRS-1 phosphorylation was increased gradually with the increasing concentration of gAd.These results suggest that gAd can promote glucose uptake by 3T3-L1 adipocyte model with generated insulin resistance.This may be correlated with promoting insulin signal transduction and improving insulin resistance in adipocytes.

Objective To study the expression and significance of bcl-2 protein in esophageal squamous cell cancer and the surrounding tissues.Methods EnVision method was used to analyze the expression of bcl-2 protein in tissues of esophageal squamous cell cancer and the surrounding tissues from 62 patients.Results Expressions rates of bcl-2 protein were 80.3 ％ (49/61),45.9 ％ (28/61) and 67.7 ％ (20/62) in simple hyperplasia,high grade intraepithelial neoplasia and squamous cell carcinoma tissues,respectively,but 3.3 ％ (1/30) in normal mucosa tissue.There were significant differences between normal esophageal mucosa group and other groups (x2 =54.437,P ＜ 0.01).The expression of bcl-2 had no differentiation in tissue differentiation grade and degree of invasion of carcinoma (x2 =0.219,x2 =5.878,P ＞ 0.05).But it had significant relationship between the expression of bcl-2 and lymph node metastasis (x2 =4.120,P ＜ 0.05).Conclusion bcl-2 may predicting the occurrence of esophageal squamous cell cancer in early stage,and may be regarded as an useful index for prognosis.
