BACKGROUND: Both electroacupuncture and salviae act on prevention and treatment ofis chemia-reperfusion injury, but, whether such action is achieved or not by coordination of both? OBJECTIVE: To probe into the effects of electroacupuncture and salviae on expression of myocardial cellular heat-shock protein 70mRNA that acts on protecting myocardium and on dopamine level that is the mark for myocardial injury after ischemia-repeifusion as well as the interaction between electroacupuncture and salviae. DESIGN: Factorial design of two factors. SETTLNG: Department of Anesthesia of Renji Hospital Affiliated to Shanghai Second Medical Scientific University. PARTICIPANTS: The experiment was performed in Animal Experimental Room of Renji Hospital from September 2001 to December 2002, in which 24 healthy New Zealand white rabbits were employed and randomized into 4 groups, 6 rabbits in each, named ① ischemia-reperfusion group (IR group), ② electroacupuncture group (EA group), ③ salviae group (SA group), ④ electroacupuncture + salviae group (ES group). METHODS: ① IR group: ischemia-reperfusion model was prepared by clipped the anterior descend branch of cardiac coronal artery for 30 minutes and released for 2 hours. ② EA group: modeling was done as the previous method. Twenty minutes before ischemia, electroacupuncture was done on Neiguan (PC 6), Yunmen (LU 2) and Lieque (LU 7), 0.8 V in voltage, 3.0-4.0 Hz in frequency. ③ SA group: modeling was done as the previous method. Before ischemia, salviae was injected intravenously once at 1.5 mg/kg, and was injected before and after reperfusion once respectively at 1.0 mg/kg. ④ ES group: modeling was done as the previous method. Both electroacupuncture and medication were applied in the group. The content of dopamine was determined in blood before ischemia,30 minutes after ischemia and 2 hours after reperfusion successively in rabbits of every group. Reverse transcription-polymerase chain reaction (RT-PCR) was used to determine myocardial heat-shock protein 70mRNA expression in ischemic and non-ischemic areas. RESULTS: After supplemented, 24 rabbits entered result analysis. ① Expression of myocardial heat-shock protein 70mRNA: that after ischemia and reperfusion was increased significantly compared that before ischemia in every group (P ＜ 0.01). That in the rest 3 groups was all higher than IR group,and that in ES group was higher than EA and SA groups (F=4.48, P ＜0.05). CONCLUSION: ① Both electroacupuncture and salivae stimulate expression of heat-shock protein 70 mRNA after ischemia and reperfusion, enhance protein stability of heat-shock protein 70 and alleviate myocardial damage. ② Both electroacupuncture and salivae inhibit increased dopamine content in the body after ischemia and reperfusion, reduce dopamine mediated injury and protect myocardium. ③ Coordination is present between electroacupuncture and salivae.

BACKGROUNDIressa is the inhibitor of epidemic growth factor receptor and mainly used to treat non-small cell lung cancer (NSCLC). The aim of this study is to evaluate the antitumor efficacy and toxicity of Iressa in the treatment of advanced NSCLC patients who had failed to previous chemotherapy.

METHODSTwenty-four patiets with advanced NSCLC who were previously treated with chemotherapy received 250mg of Iressa orally once daily until disease progressing or intolerable toxicity developing. Tumor evaluation was performed before treatment. Then for every four weeks after administration they recevied the examination; after administration for sixteen weeks, examination was repeated once every eight weeks.

RESULTSAll twenty-four patients could be evaluated. One case got complete response, eight cases got partial response, three had no change and twelve had disease progression. So the response rate was 37.5%, the stable disease rate was 12.5%, and the clinical benifit rate was 50.0%. Median time to disease progressing was 87 days. All patients were followed up for two years and 1- and 2-year survival rate was 33.3% and 12.5% respectively. The common adverse effects were skin reaction and diarrhea and no grade III or IV toxicity was observed. Two cases were suspected of pulmonary interstitial changes and the treatment ended.

CONCLUSIONSIressa is effective in treatment of advanced NSCLC patients who had failed to previous chemotherapy and the adverse effects are tolerable. So Iressa is one of the best choice for NSCLC patients who need two or more line therapy.

Objective To investigate the significance of quantitative thermal testing (QTT) in the diagnosis of diabetic peripheral neuropathy. Methods One hundred and sixty-nine diabetic patients with neurological deficit (DM group) and 53 age-matched healthy controls underwent the determination of cold threshold (CT), warm threshold (WT), clod pain threshold (CPT), warm pain threshold (WPT) in both dorsum of hand and dorsum of foot. DM group were divided into subgroups with a course of disease > 5 years or with a course of disease ≤ 5 years, or divided into subgroups with normal or abnormal nerve conduction study (NCS). Results CT and WT of DM group with a course of disease ≤ 5 years ((29.6 ± 1.4), (26. 5±4. 3) ℃ ; (35.9±3.0), (41.3±4. 0) ℃) were higher than the health controls' ((30. 2±1.2), (29.1±1.5) ℃; (35.0±1.9), (36.5±1.5) ℃, respectively; t=3.27, 6.63, 2.80, 8.61, all P< 0. 05). The CT and WT of DM group with a course of disease > 5 years' ((28. 2±4. 0), (23. 1 ±7.9) ℃ ; (37.0±4. 7), (42. 6±4. 2) ℃, respectively) were higher than the DM group with course of disease≤ 5 years(t =4. 09, 4.63, 2.55, 2. 68 ,all P <0. 05). CT and WT of the normal NCS group((29. 5 ± 1.8), (27.0±4. 6) ℃ ; (35.0±1.9), (40. 9±3. 8)℃, respectively) were higher than the healthy controls' , and the difference was significant(t =3.22, 4. 17, 3.51,9. 95,all P<0.01). The frequency of abnormal QTT in DM group was higher than that of NCS in DM group. The QTT and NCS of DM group with a course of disease >5 years were higher than these in DM group with a course of disease ≤5 years; the frequency of abnormal WT in DM group(86. 4% ,146/169)was higher than that of CT in DM group(68. 1% ,115/169,x2=15.49, P<0.01), the frequency of abnormal QTT in the dorsum of foot in DM group was higher than that in the dorsum of hand in the DM group. PT of diabetic patients were higher than that in the healthy controls. Condusions QTT is more sensitive than NCS in the diagnosis diabetic peripheral neuropathy, which is neeossary to assist NCS when diabetic peripheral neuropathy is suspected, WT in dorsum of foot is a sensitive parameter in the diagnosis of diabetic peripheral neuropathy.

Rapid detection and classification of bacteria colonies ( Escherichia coli, Listeria monocytogens and Staphylococcus aureus) were investigated by using hyperspectral imaging. The hyperspectral reflectance images (390-1040 nm ) of bacterial colonies on agar plates were collected. Bacterial spectra were extracted automatically based on the masks produced by segmenting a band difference image using the OTSU method. Full wavelength and simplified PLS-DA models were established for classification of bacterial colonies. For the full wavelength model, the overall correct classification rate ( OCCR) and confident OCCR for the prediction set were 100% and 95. 9%, respectively. Besides, competitive adaptive reweighted sampling ( CARS), genetic algorithm ( GA ) and least angle regression-least absolute shrinkage and selection operator ( LARS-Lasso) were used to select feature wavelengths for the development of simplified models. Among them, the CARS-model outperformed the other two in terms of precision, stability and classification accuracy with OCCR and confident OCCR of 100% and 98. 0% for the prediction set, respectively. It was demonstrated that hyperspectral imaging was an effective technology for nondestructive detection of bacterial colonies with high accuracy and high speed. The allocated feature wavelengths by CARS could lay theoretical basis for developing low cost multispectral imaging systems for bacterial colony detection.
