With Jianyu (LI 15), Jianliao (TE 14) and Jianzhen (SI 9) for instance, the three acupoints used to treat shoulder bi syndrome by needle knife, and through traceability and researching constant structure, the acupoint position, insertion trace, manipulation and clinical significance of needle knife medicine were discussed. Accurate position is one of the characteristics of acupoints selection of needle knife medicine. As for the acupoints selection method, the mean of body surface localization is always used. The phanerous or palpable bone processes, muscles and tendons are taken as positioning marks; pressing areas where appear sour, numb, or distensible and other sensations is considered as the principle of press positioning. So acupoints position method is the combination of observation and palpation. Different insertion methods can effectively relieve the accretive bursae synovialis, tendon, joint capsule and the compressed nerve, so that shoulder bi syndrome is relieved.

AIM: To verify the neuroprotective effect and optimize the therapeutic dose and time window of picroside Ⅱon cerebral ischemic injury in rats .METHODS:The forebrain ischemia model was established by the method of bilateral common carotid artery occlusion ( BCCAO ) .The successful model rats were randomly divided into 16 groups according to orthogonal design and treated by intraperitoneal injection of picroside Ⅱat different ischemic time poinis and different doses .The changes of the nerve fiber myelin were observed by fast green staining .The immunohistochemical assay and Western blotting were used to quantitatively and qualitatively determine the expression of myelin basic protein (MBP). The mRNA level of MBP in the brain tissues was tested by reverse transcription polymerase chain reaction (RT-PCR).RE-SULTS:Picroside Ⅱ increased the expression of MBP and decreased demyelination after cerebral ischemic injury .The best therapeutic time window and dose were:(1) ischemia for 2.0 h with picrosideⅡat dose of 10 mg/kg according to the results of fast green staining;(2) ischemia for 2.0 h with the dose of 10 mg/kg according to the results of immunohisto-chemical assay;(3) ischemia for 2.0 h with the dose of 10 mg/kg according to the analysis of Western blotting;(4) is-chemia for 1.5 h with the dose of 20 mg/kg according to the detection of RT-PCR.CONCLUSION:Given the principle of the lowest therapeutic dose with the longest time window , the optimized therapeutic dose and time window for rat cerebral ischemic injury is intraperitoneal injection of picroside Ⅱat the doses of 10~20 mg/kg and the time window of ischemia for 1.5~2.0 h.

Objective:To investigate the effect and the mechanism of T cell vaccination in inducing heterologous antigen specific immune tolerance Methods:T cell vaccination were made from the spleen cells of SD rats, which were induced by ConA and were challenged with the spleen cells of guinea pig (the heterologous specific antigen) Normal SD rats were vaccinated intraperitoneally with TCV or 1640 culture buffer(blank control) respectively One way mixed lymphocyte reaction(MLR)?the apoptosis of peripheral T cells and the rate of CD4/CD8 in peripheral blood were assayed before and after vaccination.Results:MLR showed that the response captivity of SD rat spleen cells in TCV group were suppressed significantly after vaccination(P

Objective To develop Z-score reference ranges for tricuspid annular plane systolic excursion(TAPSE) in normal fetuses from the measurements of gestational age(GA),biparietal diameter (BPD) or femur length(FL) using fetal echocardiography.Methods A retrospective cross sectional study of 1012 singleton normal fetuses were performed.The gestation age ranged from 20 to 41 weeks.Non-cardiac fetal biometric parameters included GA and BPD and FL were measured and calculated GA based on menstrual age.TAPSE was measured in a standard apical four-chamber view by free angle M-mode echocardiography.Normal Z-score ranges were developed for TAPSE using GA,BPD and FL as independent variables.These were accomplished by using first standard regression analysis and then weighted regression of absolute residual values for each parameter in order to adjust for inconstant variance.Results Linear regression model was the best description of the data in each case and correlations between TASPE and independent variables (GA,BPD,FL) were excellent.Heteroscedasticity of standard deviation (SD) with increasing independent variables also could be modeled with a simple linear regression.According to these equations,TAPSE Z-score =(the actual measurement of TAPSE-predicted TAPSE)/prediction SD.Conclusions Normal reference ranges and Z-scores for TAPSE have been provided.These normative data may be useful tools for assessment of fetal TAPSE,to evaluate fetal right ventricular function more accurately and effectively.

Objective ABCG2(ATP-binding cassette superfamily G member 2)is a member of ABC transporter superfamily,and participates in the mechanisms of high resistance to chemotherapeutic agents in tumor treatment.The aim of present study is to investigate the expression and significance of ABCG2 in lung cancer tissues.Methods Lung cancer tissues were obtained from 83 patients(64 NSCLC,19 SCLC)by bio-autopsy or surgery.No patients had received chemotherapy or radiotherapy before bio-autopsy or surgery.83 lung cancer specimens were analyzed for ABCG2 protein expression by using immunohistochemistry.Negative controls had the primary antibody eliminated.Human placenta tissues were used as positive control.In addition,five specimens of normal lung tissues were included for comparative study.Results The present study confirmed the predominant localization of ABCG2 transporter in plasma membrane.Some of ABCG2-positive tumors showed mixed membranous and cytoplasmic staining.ABCG2 expression was found in 71.9%(46/64)of NSCLC and 10.5%(2/19)of SCLC.The level of ABCG2 expression was significantly higher in NSCLC than in SCLC(P

Objective To evaluate CT in the diagnosis of small bowel obstruction in children. Methods Thirty one cases with small bowel obstruction manifestations on CT and plain radiograph were analysed. The age ranged from 9 months to 14 years, male 17 cases, female 14 cases. There were 29 acute small bowel obstructions, and 2 chronic obstruction. Seven cases had history of previous abdominal operation. Results Corred diagnosis was made in 19 cases and 29 cases respectively by plain film and CT. The accurate etiologic diagnosis could be made by CT in 18 cases, including small bowell stone 4 cases, intussusception, 5 localized infection and adhesion 6 intraluminal bowel duplication, 1 congenital umbilical hernia, congenital malrotation of the intestine 1 case.Combined with history of abdominal operation the accurate CT etiologic diagnosis increased to 25 cases.There were 4 CT false negative cases and 2 plain film false negative cases. Conclusion The CT is obviously superior to plain radiograph in detecting strangulation and gas in bowel wall,better dilineating the transitional segment of bowel stenosis thereby demonstrating the case of obstruction which is very helpful for clinical management.
