Results: After intervention, the MMSE score changed significantly (P<0.01), and the total effective rate was 83.3%.
Conclusion: Acupuncture-moxibustion can significantly improve the cognitive function of AD patients, beneficial to the general promotion of the quality of life.

Objective:Through analyze the uncertainty sources in verification about defibrillation analyzer of DA-1 type, assess and verify of defibrillation energy uncertainty, repeatability and stability to ensure the quality of the analyzer. Methods:The maximum permissible error, energy display resolution, releasing energy measurement repeatability three aspects:source of uncertainty was analyzed and evaluated. Results:On the basis of WSB64-2003“verification regulation for cardiac defibrillators & cardiac defibrillator-monitors”, the relative expanded uncertainty can be obtained. Conclusion:Through analysis and evaluation, the source of the uncertainty of the results of defibrillation analyzer are conform to rules of the regulation, the defibrillation analyzer can detect the defibrillator of clinical to ensure the quality and safety.

OBJECTIVE:To establish a method for testing the bacterial endotoxin in ceftazidime/tazobactam sodium for injection.METHODS:Based on the bacterial endotoxin test method stated in Chinese Pharmacopoeia(2005 edition),an interference test was conduced on different batches No.of ceftazidime/tazobactam sodium samples using actachypleus amebocyte lysate(TAL)from different companies.RESULTS:No interference was found in the bacterial endotoxin test after ceftazidime/tazobactam sodium for injection was diluted to 5.0 mg?mL-1.Its limit value of bacterial endotoxin was 0.1 EU?mL-1.CONCLUSION:Actachypleus amebocyte lysate test was suitable for determining bacterial endotoxin in ceftazidime/tazobactam sodium for injection.

Intractable abdominal distension refers to the reasonable application of the general dialectical therapy with no significant efficacy. Professor SHI Zai-xiang believes that on the basis of hepatosplenic disorder, there are the etiology and pathogens of spleen yang not raising and spleen and stomach in disorder in intractable abdominal distension, which should be treated with raising qing yang, tonifying qi, and consolidating the superficial resistance. Therefore, modifiedBuzhong Yiqi Decoction was used; as for abdominal distension with blood stasis and meridian stasis, the treatment should be motivating blood circulation and eliminating stasis, motivating qi stagnation, and making free the passage of blood in the vessels, which should be treated withGexia ZhuyuDecoction combined withDahuang Zhechong Pills; as for abdominal distension with lung qi stagnation, the treatment should be motivating lung qi, moisturizing dryness and laxation, promoting qi and eliminating swelling, which should be treated with modified WenbaiPills; as for abdominal distension with cold and yang deficiency, the treatment should be warming and expelling cold, warmly tonifying spleen and kidney, which should be treated withJiuzhuan Yuhu Pills; as for abdominal distension with extra meridians tiredness and deficiency of yin and yang, the treatment should be tonifying extra meridians, warmly tonifying yin and yang and tonifying liver and kidney, which should be treated with modified Roucongrong Pills. Intractable abdominal distension needs the overall dialectical and alternative treatment.

Objective:The platelet thermostatic storage box is widely used in hospital, laboratory, and blood station. It is very necessary to develop a calibration device to ensure the accuracy of the technical parameters.Methods: Using Infrared emitter, digital temperature sensor, ARM microcontroller etc to form a calibration device, the parameters of temperature, amplitude and frequency are processed. Data is transferred by Bluetooth communication, final; the test report is printed out for clinical.Results: The calibration device is developed, it can detect the important performance parameters of preservation box, it can ensure the safety of patient's blood transfusion. Conclusion: This calibration device is simple operation, strong practicability, stable performance; it can detect the technical parameters of platelet thermostatic storage box through experiment to ensure the safety and quality.

Neoadjuvant chemotherapy (NAC) has been widely used in ⅡA, ⅡB, ⅢA stage and locally advanced breast cancer. The best way to evaluate NAC effect is to detect the changes in total tumor lesion volume by three-dimensional reconstruction under magnetic resonance imaging (MRI). At present, it is a hotspot for many scholars to effectively evaluate the efficacy of NAC and the impact of shrinkage modes on the evaluation after NAC in breast cancer by combination of multiple parameters, such as the area under receiver operating characteristic curve (ROC), time-intensity curve (TIC) type and minimum apparent diffusion coefficient (ADC). To provide more practical and accurate means and methods in evaluating the effect of NAC in breast cancer for clinic is the medical researchers′eternal target.

With the continuous advent of new types of electron microscopes and the continuous improvement and development of electron microscope technique , biological electron microscope tech-nique has become one of the important experimental means in the fields of biology , molecular biology, basic medicine and clinical medicine , Department of Pathology of College of Basic Medical Sciences in Jilin University has reviewed the teaching feature and teaching status of biological electron microscope technique based on the training objectives of postgraduate education.

Objective: To study the morphological changes of erythrocytes in hyperl ipemia. Methods: Wistar rats used were divided into normal control group (NC) an d hyp erlipemia group (HL, fed with high lipid diets). The morphological changes of er ythrocytes were observed by SEM, and classified and counted. Results: Compared with NC,percentage of normal erythrocytes in HL were decreased from 76.4 % to 45.7%. The percentage of echinocytes, spherostomatocytes and target cells w ere increased from 4%, 2.2%, 1.5% to 17.3%, 10.4%, 5.8% respectively. The nu mber of ridged cells and abnormal cells was a little increased.Conclusion: The number of abnormal erythrocytes was significantly increased in h yperlipemia.
