The levels of triglyceride(TG)and free fatty acid(FFA)in serum,liver,skeletal muscle,and pancreas of lipoprotein lipase gene knockout heterozygous(LPL+/-)mice and C57 mice were determined.Intraperitoneal glucose tolerance test(IPGTT)was performed to evaluate insulin sensitivity and β-cell function.The results showed that the Iipid content in 16 weeks LPL+/- group did not increase significantly.The TG and FFA contents in 28 weeks LPL+/- group were significantly higher than those in control and 16 weeks LPL+/-group(all P<0.05).In 50 weeks LPL+/- group,FFA levels in serum and pancreas,and TG content in pancreas increased significantly compared with other three groups(all P<0.05).The IPGTT result showed that the blood glucose levels increased from 15 to 120 min,not at 0 and 5 min.The blood glucose levels during 30-120 min increased significantly in 50 weeks LPL+/- group compared with other three groups(P<0.05).Fasting insulin(FINS),homoestasis assessment of insulin resistance(HOMA-IR)and pancreatic β cell function also increased gradually with age.FINS and HOMA-IR in 28 weeks LPL+/- group were higher than those in control and 16 weeks LPL+/- group.These results suggest that LPL is a key enzyme in lipid metabolism and plays a crucial role in the development of insulin resistance and diabetes.

OBJECTIVETo compare the differences in the clinical efficacy on Alzheimer's disease between acupuncture and medicine.

METHODSOne hundred and forty-one patients were randomized into an acupuncture group (72 cases) and a medicine group (69 cases). In the acupuncture group, the needling technique for benefiting qi, promoting blood circulation, regulating mind and improving intelligence was used at Shenting (GV 24), Baihui (GV 20), Fengchi (GB 20), Wangu (GB 12), Danzhong (CV 17), Zhangwan (CV 12), Qihai (CV 6), Xuehai (SP 10) and Zusanli (ST 36). The supplementary acupoints were selected according to the symptoms and physical signs. Acupuncture was given once a day and 6 treatments were required for a week. In the medicine group, the choline sterase inhibitor, donepezil (aricept) was prescribed for oral administration, 1 tablet (5 mg) each time, once every night. Four weeks later, the dose was increased to 2 tablets (10 mg) each time. In the two groups, the treatment of 4 weeks made one session and 4 sessions were required. The changes of scores before and after treatment in the minimum mental state examination (MMSE), the activity of daily living scale (ADL), Alzheimer's disease assessment scale-cognition (ADAS-cog) and the digit span (DS) were observed.

RESULTSAfter treatment, scores of MMSE and DS were increased as compared with those before treatment (both P < 0.05) and scores of ADL and ADAS-cog were reduced as compared with those before treatment. The score differences in MMSE, ADL, ADAS-cog and DS before and after treatment were significant in the two groups (all P < 0.01).

CONCLUSIONThe needling technique for benefiting qi, promoting blood circulation, regulating mind and improving intelligence significantly improves the overall function, cognition and activity of daily life in the patients of Alzheimer's disease and the efficacy is better than donepezil.

Objective To analyze the mammographic features of invasive lobular carcinoma (ILC)compared to those of invasive ductal carcinoma (IDC).Methods Twenty cases with ILC and 95 cases with IDC were retrospectively evaluated by two breast radi-ologists according to the Breast Imaging Reporting and Data System (BI-RADS)lexicon.The mammographic findings were com-pared between ILC and IDC with the independent samples chi-square test or Fisher’s exact test,as appropriate.Results Mass was the most common finding in both ILCs and IDCs,but less frequent in ILCs (36.4% vs 63.9%,P =0.008).Mass in ILCs was more frequently lobular or irregular shape with spiculated margin.Architectural distortion and focal asymmetry were more frequent in ILCs than in IDCs,however,the differences were no significant.The frequency of calcifications was not significantly different between the two groups.The distributions of calcifications were more regional in ILCs,and more segmental or linear in IDCs (P =0.01).Conclu-sion ILCs are more usually shown as non-mass appearances on mammography.ILCs that appeared as mass are more frequently ir-regular in shape with spiculated margins.

Objective To make up an exercise prescription based on traditional Chinese medical training (EP-TCMT) for patients with stable chronic obstructive pulmonary disease (COPD).Methods Eighty-five pa- tients with stable COPD were randomly divided into a control group (CG group),a traditional Chinese medicine group ( TC group) and an exercise prescription group ( EP group).The patients in the TC and EP groups were giv- en intensive training for 8 weeks.Their 6 rain walk distance (6MWD) and Borg scale scores were assessed before and after the treatment.Results The 6MWD in the TC group increased from 337.68?59.18 m to 386.14?76.71 m,while those in the EP group improved from 348.00?55.94 m to 425.17?53.22 m.The Borg scale scores in the TC group decreased from 3.14?1.94 to 2.32?1.25,while those in the EP group declined from 3.45?1.84 to 1.72?0.70.Conclusion Making up EP-TCMTs is feasible.Additional treatment was found to improve exercise tolerance and decrease dyspnea in COPD patients.Exercise therapy based on traditional Chinese methods is easy and safe.

Objective To compare four methods of monitoring vascularization of tissue engineered bone in the rhesus so as to find our the best. Methods Twenty-five lower limbs of 13 rhesuses were used in this study to make models of tibial diaphyseal defect of 20mm which were to be fixed with an AO reconstruction plate of 7 holes. The monkeys were randomly divided into five groups according to defect filling materials: group A:?-tricalcium phosphate (?-TCP) and bone marrow stromal cells (BMSCs) and blood vessel bundles; group B:?-TCP and blood vessel bundles; group C:?-TCP and BMSCs; group D:?-TCP; group E: blank. Perfusion weighted MR imaging (PWMR), X-ray, radionuclide imaging and histological examinations were carried out at weeks 4, 8, 12 postop- eratively. The maximum slope rates of the single intensity-time curve (SS_(max)) and values of baseline (Sl_(?))were calculated at the same time points. Transmittances of the X-ray films were assessed. Ratios between isotope counts in region of interest (ROI) were calculated. Chinese ink perfusion and calculation of blood vessel areas were done for histological examinations, Results Compared with other groups, the SS_(max) in group A was the highest at weeks 4, 8, 12 postoperatively. In group A, the SS_(max) at week eight was significantly higher than that at week four (P= 0. 003), and the SS_(max) and transmittance of X-ray were negatively related at week 12 after operation (rs=-0. 892, P=0. 042), but the SS_(max) and blood vessel area were positively related (rs=0. 894, P=0.041)Conclusions PWMR can be a sensitive, quantitative, noninvasive and non-radiant method to monitor vascularization of tissue engineered bone, because SS_(max) of the single intensity-time curve of PWMR can reflect the most accurately the process of vascularization of tissue engineered bone.

Objective To probe into the effect of health education pathway in stoke unit,and provide evidence for formulating an effective health education programs of stroke unit.Methods A total of 265 stroke patients were divided into intervention group and control group randomly.Patients of control group were given conventional health education while those in the intervention group received conventional health education.Results The 3-month and 1-year follow-up rate were 96.96％ and 82.71％ respectively in intervention group,There were statistically significant differences between the two groups(x2 =20.267,9.546;P ＜0.01 ).the knowledge level and service satisfaction were 90.91％ and 9.4.70％ respectively in intervention group,There were statistically significant differences between the two groups( x2 =15.481,11.362;P ＜ 0.01 ).Conclusions The health education pathway in stroke unit could enhance satisfaction degree of patients,create high quality nursing service and promote the full rehabilitation of patients.It' s worth of clinical generalization.

An old male patient visited the hospital due to shortness of breath and palpitation for 6 h, with fever 3 days before and pump failure at admission. Having no risk factor of coronary diseases such as hypertension, diabetes mellitus and obesity, with ST-T changes and abnormal Q wave on ECC, the signs were compatible with those of acute anterior wall myocardial infarction, while the characteristics of cardiac biomarkers ( significant increase in Troponin I and creatine kinase's isoform, and normal creatine kinase) were not in accordance with those of acute myocardial infarction. Emergency angiography was performed, which indicated normal coronary artery, normal pulmonary artery and global systolic dysfunction of left ventricle. The diagnosis of acute severe myocarditis was established, and intra-aortic balloon pump (IABP) was employed to provide hemodynamic support. Severe myocarditis mimicking acute myocardial infarction may be fatal, and can be easily misdiagnosed. Careful analysis of clinical manifestations, early diagnostic angiography and possible IABP placement are important for the successful treatment.

OBJECTIVETo assess the potential impact of warming climate in winter to the scale and severity of schistosomiasis epidemics in China.

METHODSBased on the data of mean temperature and monthly minimum temperature in January from 126 (out of 733) weather observation stations in China, the trend and oscillation amplitude was analyzed. The impact of warming climate in winter to the scale of schistosomiasis spreading was assessed, using the indices of 0 degrees C mean temperature and -4 degrees C mean monthly minimum temperature in January. Correlation between these two indices was analyzed.

RESULTSEvidences showed the warming climate in winter was seen all over China with the mean monthly minimum temperature and the mean temperature in January had increased 1.3 degrees C and 0.9 degrees C since 1986. The contours of mean monthly minimum temperature -4 degrees C and mean temperature 0 degrees C in January moved 1 - 2 latitudes northward.

CONCLUSIONThe warming climate phenomenon seen in winter was considered favorable to the living of snails in winter, resulting in the possible increase of northward spreading of snails.Thus, monitoring of snails should be paid special attention.
