Objective To understand the motivation of blood donation and the main influencing factors of blood donation behav-ior to formulate a targeted recruitment strategy.Methods A stratified cluster sampling method was adopted to perform the ques-tionnaire investigation on the influencing factors of blood donation without payment in 583 non-donors and 554 blood donors of Fos-han City.The analysis was performed by using the chi square test and Logistic regression analysis method.Results The character-istics of blood donation population were more males,aged 20-<30 years old,high school or secondary education,monthly income in 1 000-<3 000 Yuan;the main motivation for donating blood wasdevotion to love and social responsibility;the blood donation behavior was affected by the factors ofdevotion to love and social responsibility,give repeated donors certificate and medalfear of infectious disease and blood donation will affect healthfear of painandblood donation site traffic inconvenience and other factors.Conclusion The factors of incentive measures,barriers measures,psychological factors,blood donation services,and so on will affect the citizens to donate blood.Different recruitment strategies should be developed for different crowds.

Objective To analyze the related factors of donor′s donation reaction in first time apheresis platelets to provide a basis for formulating the preventive measures of donation reactions in apheresis platelets.Methods The donation data in 743 cases of first time apheresis platelet in this blood station were retrospectively analyzed,and the factors possible influencing the donation reaction occurrence in donors of the first time apheresis platelet were performed the univariate Logistic regression analysis,then observation indicators with statistical significance were performed the multivariate Logistic regression analysis.Results The univariate Logistic regression analysis showed that gender,age,body mass,whole blood donation history were the influencing factors of donors′ donation reaction in the first time apheresis platelets.In multivariate Logistic regression analysis,the main factors were age (OR=0.301,P<0.05),body mass (OR=0.411,P<0.05)and whole blood donation history(OR=0.441,P<0.05).Conclusion Age,body mass and whole blood donation history are the main influencing factors of donors′ donation reactions in the first time apheresis platelets.

Objective To discuss the imaging findings and pathological features of primary pulmonary lymphoepithelioma-like carcinoma (LELC). Methods Imaging and pathological data of 13 patients (9 male and 4 female, age from 17 to 72 years, median age 52 years) with pathology-proven primary pulmonary LELC from January 2010 to March 2015 were retrospectively analyzed. Thirteen patients underwent X-ray examination, two of them underwent non-enhanced CT scan, eight underwent non-enhanced and enhanced CT scans, one underwent non-enhanced MR scan. All imaging data including location, number, shape, size and density of lesions were analyzed by two experienced chest radiologists respectively and reached an agreement after consultations. Surgery was performed in 11 cases and aspiration biopsy in 2 cases. HE staining was performed in all cases and immunohistochemistry staining in 6 cases. Results All thirteen primary pulmonary LELC were unilateral. Nine peripheral tumors and four central tumors were identified. Lobulations (n=11), spiculas (n=7), vessel convergences (n=3), vascular encasements (n=2), pleural indentations (n=4) and punctuate calcification sign (n=1) were seen in the CT images. Thirteen tumors had diameters ranging from 1.3—11.0 cm, average diameter of (4.4 ± 2.7) cm, and all showed homogeneous density in non-enhanced CT. CT value ranged from 22—48 HU, average value of(34± 10)HU, and during arterial phase it ranged from 33—70 HU, average value of(53 ± 13)HU;and during venous phase it ranged from 43—86 HU, average value of(66±14)HU;the tumor had long T1 and long T2 signal in non-enhanced MR scan, and signals were homogeneous. Pathologically, the tumor was from pleomorphic epithelial with large cells, syncytia in the infiltration of lymphocytes or accompanied with collagenzation. Large nucleus showed vacuole-shape. Immunochemistry CK(+), P63(+), CK5/6(+), CK14(-) supported the diagnosis of LELC. Conclusions There are certain imaging characteristics for primary pulmonary LELC. Histopathological and immunohistochemistry examination could provide the definitive diagnose.

To study action mechanism and time of administration of indomethacin in SMAO shock rabbits. Method:Thirty-two SMAO shock rabbits were randomly divided into four groups: control group A,indomethacin 5mg/kg I.V. at the occlusion of superior mesenteric artery (group B), indomethacin 5mg/kg L V. immediately after clamp being removed(group C) and the same dose 30min after clamp being removed(group D). Survival rate,hemodynamics, plasma calcium, myocardial calcium, TXB_2 and 6-keto-PGF_1. levels were observed in 4h shock period. Myocardial apecmen were examined with electronic microscope. Result: After indomethacin I.V,the survival rate was higher and bemodynamie better than those of controll. The plasma calcium level remained stable in indomethacin groups. Myocardial calcium content of group B and C was lower than that of group D and A. The TXB_2 and 6-ketoPGF_1. contents were similar in all groups. Under electronic microscope, the damages were slightest in group C and most serious in group D and A among the four groups. Conclusion:Indomethacin has a beneficial effect on the SMAO shock rabbits ,the mechanism of which can be related to improving myocardium contractivity as well as to blocking calcium channel,rather than the action through prostaglandins. The time of administration should be early as possible after shock.

Objective To investigate the attention network in patients with obsessive-compulsive disorder (OCD) and generalized anxiety disorder (GAD).Methods 31 GAD patients,31 OCD patients and 30 healthy controls (HC) were tested with attention network test.Results There were significant differences in the main effects with respect to the alerting network(15.87±5.24,26.77±4.33,34.87±3.47) (F=4.619,P=0.012)) and the executive network(114.84±9.64,122.45±5.57,96.57±5.45) (F=3.388,P=0.038) among the OCD,GAD and HC groups.The three groups did significantly differ in RT of the attention network (F=19.808,P=0.000).For the HC group,there was significant main effects with respect to cue conditions(F=29.699,P=0.000).There was a significant correlation between the executive network and Hamilton anxiety scale (r=0.351) and also a significantly negative correlation between the alerting network and Hamilton depression scale (r=-0.267).Conclusion There are attention network damages in patients with OCD and GAD,which may be involved in the impairment of emotion.

Nitrogen-doped carbon nanoparticles (N-CNPs) with a fluorescence quantum yield of 15.1％ were prepared from sucrose and urea in oleic acid medium by a one-pot solvothermal method.A new approach for quick,sensitive,and selective determination of free chlorine in water was developed based on fluorescence quenching of N-CNPs.There existed a good linear correlation between the fluorescence quenching and the concentration of ClO-in the range of 0.05-25.00 μmol/L.The limit of detection (LOD,S/N =3) was estimated to be 23 nmol/L.This method can be applied to the determination of free chlorine in real water samples.

The mollusicidal effect and toxicity to fish with META-Li in field were tested in mountain areas in Zhejiang Province. The snail control test, which had 3 groups including a META-Li group, niclosamide group and control group, were performed by the spraying method. The adjusted mortalities of snails in the META-Li group on the 3rd, 7th and 15th day were 89.76% , 87.98% and 94.10% , respectively, in the niclosamide group were 89.70% , 83.22% and 94.72% , respectively .and there was no significant difference between the two groups ( P > 0.05), but they were decreased obviously compared with the control group, which were 9.24% , 9.50% and 15.21% , respectively(P <0.05). The toxicity test to fish with META-Li included 3 groups, namely a high concentration META-Li group, low concentration META-Li group and control group, and none fish was dead. It is suggested META-Li has low toxicity to fish, and is suitable to snail control in aquiculture areas.

Objective To investigate the value of diffusion kurtosis imaging (DKI) in diagnosing early diabetic nephropathy. Methods Twelve pigs were divided into the experimental group (7 pigs) and the control group (5 pigs), used the random number table method. The experimental group was fed with high?fat high?sugar diet,and then repeatedly injected small doses(50 mg/kg) of Streptozotocin (STZ) through the ear vein. Meanwhile,the control group was fed with normal diet and injected with the same dose of citric acid?sodium citrate buffer solution.After the type 2 diabetes was established successfully, T1WI, T2WI and DKI sequence imaging were performed every month for 2 pigs from the experimental group and the control group,respectively.Mean kurtosis(MK), axial kurtosis (K∥), radial kurtosis (K⊥), fractional anisotropy (FA) and mean diffusivity(MD) were measured on the pseudo?color map of the post?processing workstation. fasting blood glucose(GLU),insulin (INS),renal function, urine routines and random albumin creatinine ratio(RACR) were measured before MRI scan. Specimens from bilateral kidneys were taken for pathological examination after MRI scan. The paired t test was used to compare the parameter values of the cortex and medulla. Independent sample t test was used tocompare the parameter values of the experimental group and the control group. Results In the experimental group,the MK, FA values of medulla were 0.66±0.07 and 0.19± 0.04, the MK, FA values of cortex were 0.60±0.06 and 0.16±0.03.In the control group,the MK, FA values of medulla were 0.59±0.03 and 0.20±0.04, the MK, FA values of cortex were 0.53±0.03 and 0.17±0.04.The MK and FA values of medulla were increased compared with the cortex and the difference were statistically significant (P<0.01). The MK, K⊥ values of cortex and medulla were increased in the experimental group compared with the control group and the difference were statistically significant (P<0.05). There was no significant differences in the K∥, FA and MD values between two groups (both cortex and medulla, P>0.05). Conclusion DKI sequencehas certain value in the diagnosis of early diabetic nephropathy, and to some extent reveals the pathological change in early diabetic nephropathy.
