The levels of serum lipids, lipoproteins and apoproteins were determined in 36 age over 90 year long-living people, 43 patients with old myocardial infarction (OMI) and 56 normal subjects of the age 40 to 64 years old. The resutts showed that: the ratioes of HDL-c/TC, HDL-c/LDL-c and ApoA_1/ApoB_(100) of the long-living people were higher than that of the patients with OMI; the levels of TC, TG, LDL-c, VLDL-c, ApoB_(100) and ApoA_1 in longevity group were lower than that of OMI group; no significant difference of HDL-c level was found between longevity and OMI group. Compared with normal group, the serum concentration of ApoA_1/ApoB_(100) ratio, TG and VLDL-c in the long-living group were obviously higher, and the serum concentration of ApoB_(100), ApoA_1 and HDL-c significantly lower. No significant differences were found in the levels of TC, LDL-c, and in the ratioes of HDL-c/TC and HDL-c/LDL-c between longevity and normal group. Stepwise regression analysis showed that the serum ApoB_(100) concentration and ApoA_1/ApoB_(100) ratio was the most important factor of longevity. It was suggested that the internal balance of serum lipids and lipoprotein metabolism in long-living people was good co-ordination, and the lower ApoB_(100) level and higher ApoA_1/ApoB_(100) ratio were probably parameters of longevity.

Objective Based on scientific research grants to explore the feasibility of analyzing the subiect's hot topics. Methotis The CRISP(Computer Retrieval of Information on Scientific Projects)database of National Institutes of Health was used to retrieve the grants related of gene mechanism of essential hypertension in 2006. We obtained concepts from the fields of title and abstract by MetaMap. and then analyzed the key concepts about genes that were found more than 3 times. Results There were 73 related grants about that from CRISP in 2006. After processing the samples by MetaMap, we got 45 high frequency concepts about genes. which were divided into seven groups. Conclusions It iS feasible to analyze and study subject hotspot by scientific research grants. and it can be used to the supplement of normal literature analysis. MetaMap is a better tool for natural language processing, but also has some limitations.

Objective To investigate the effect of warfarin on coagulation function and hemorheology index in patients with atrial fibrillation. Methods Retrospective a total of 90 patients with atrial fibrillation who underwent anticoagulant therapy from June 2014 to December 2015 in The Fourth People's Hospital of Wenling City were randomly divided into the control group and the warfarin group with 45 cases in each group.The patients in the control group were treated with aspirin, the patients in the warfarin group were treated with warfarin.The indexes of coagulation function and hemorheology were measured before and after treatment, and the effects of warfarin on patients with atrial fibrillation were observed and analyzed. Results After treatment, there was no significant change in coagulation function in the control group, the thrombin time (PT), thrombin time (TT), and partially activated thrombin time (APTT) of warfarin group were significantly increased, the difference was statistically significant (P<0.05), and the coagulation function of warfarin group was significantly higher than that of the control group, the difference was statistically significant (P<0.05).The plasma viscosity, red blood cell index, high shear whole blood viscosity, low shear whole blood viscosity and fibrinogen (FIB) were significantly lower in the two groups, the difference was statistically significant (P<0.05), and the high shear whole blood viscosity, low shear whole blood viscosity and FIB of warfarin group were significantly lower than those of the control group, the difference was statistically significant ( P <0.05 ). Conclusion Warfarin has a potent effect on platelet activation, which can produce anticoagulation by adjusting coagulation function, platelet parameters and hemorheology in patients with atrial fibrillation.

Objective To evaluate the clinical efficacy,overall survival and toxicities in the patients with advanced non-small cell lung cancer treated by liposome paclitaxel combined with nedaplatin as first-line treating.Methods 34 cases with advanced NSCLC were treated with liposome paclitaxel 150 mg/m2 on day 1 and nedaplatin 80 mg/m2 on day 1 by intravenous infusion,with 21 days as one cycle.The patients were treated with chemotherapy more than 2 cycles.Efficacy evaluation and adverse events were evaluated every 2 cycles.Results 34 patients were available for evaluation of efficacy and adverse events.The patients recieved 174 cycles of chemotherapy,and the median was 5.3 cycles.The objective response rate of liposome paclitaxel combined with nedaplatin was 32.3 ％,the disease control rate was 67.6 ％,the median overall survival was 9.5 months (95 ％ CI 6.2-10.7),1 years survival rate was 40.6 ％.The main adverse events were hematological and gastrointestinal toxicities.Frequent grade Ⅲ-Ⅳ toxicities included neutropenia (41.7 ％),anemia (17.6 ％),thrombocytopenia (8.8 ％),nausea and vomiting (8.8 ％),diarrhea (5.8 ％).Conclusions The regimen of liposome paclitaxel combined with nedaplatin is against advanced non-small cell lung cancer with high efficacy and acceptable toxicities,and it may be used as a new choice for treatment of advanced non-small cell lung cancer.

Objectives To analyze comparatively the adverse reactions of Nedaplatin(NDP)and Cisplatin(DDP)in concurrent chemoradiotherapy for locally advanced nasopharyngeal carcinoma and summarize the nursing points as well.Methods From March 2012 to March 2013,112 patients with locally advanced nasopharyngeal carcinoma were randomly divided into NDP group and DDP group.Besides intensity modulated radiotherapy for both groups,NDP group were treated with intravenous drop infusion of NDP by 100 mg/m2 and the control group with intravenous drop infusion of DDP by 100 mg/m2 both for three courses of once every three weeks (e.g.day one,day 22 and day 43 during the course).The two groups were compared in terms of therapeutic effects and incidences of adverse reactions.Results The complete remission rates of the NDP group and DDP group were 87.5%and 85.7%,respectively (P>0.05).The incidences of adverse reactions like gastrointestinal reactions and radioactive mucositis in the NDP group were significantly lower than those in the DDP group(P<0.05)and the index of platelet decrease was significantly higher(P<0.05).There were no significant differences between the two groups in terms of liver and kidney dysfunction and white blood cells decrease(P>0.05). Conclusions Chemotherapy with NDP combined with radiotherapy for locally advanced nasopharyngeal carcinoma has fewer adverse effects and is easy to be accepted by patients so that their quality of life can be improved.In the application of the two kinds of chemotherapy,we should pay attention to the adverse reactions on patients in order to give pertinent care.

ObjectiveTo assess the impact of intense pulsed light (IPL) on the dermatopathological manifestation in a Bama miniature pig model of steroid-induced dermatitis.MethodsFive female Bama miniature pigs aged two months were selected.The white skin areas with white hair at both sides of the neck served as the target area.Halometasone(0.05％) cream was applied to the right target area twice daily for 60 days to establish a model of steroid-induced dermatitis.Then,3 pigs were randomly selected and irradiated with IPL of 25 J/cm2 at the model area with an interval of 3 weeks for 9 weeks,the remaining 2 pigs receiving no treatment served as the natural recovery group.Finally,skin tissues were obtained from the left and right target areas and subjected to haematoxylin and eosin staining for the observation of histopathological changes.ResultsA significant increase was observed in the layer number of keratinocytes and thickness of dermal collagen fiber in the IPL-treated pigs compared with the pigs in natural recovery group (6.27 ± 1.26 vs.2.98 ±0.92,t =3.27,P＜ 0.01; 1.88 ± 0.19 mm vs.0.84 ± 0.15 mm,t =4.25,P＜ 0.01).Moreover,IPL irradiation resulted in the regression of telangiectasis in the dermis.ConclusionIPL may increase skin thickness,relieve flushing and improve skin elasticity efficiently.
