One hundred and five patients with non-ST segment elevation acute coronary syndrome were followed up for 1 year.They were assigned to the event group or non-event group according to the presence of endpoint events(cardiac death and nonfatM myocardial infarction).B-type natriuretic peptide level was measured at 30 days and 1 year and compared between the two groups.The results showed that the level of B-type natriuretic peptide was higher in the event group[(235±107)μg/L vs(154±49)μg/L at 30 days;(259±100)μg/L vs(143±57)μg/L at 1 year].Thus,B-type natriuretic peptide is an important prognostic factor for patients with non-ST segment elevation acute coronary syndrome.

Objective To study the inlfuence of the allicin on abnormal crypt focus(ACF). in Wister rat model. Methods 60 Wister rats were subcutaneous injected by dimethylhydrazine (DMH), according to 20 mg/kg weight, once a week, feeding 18 weeks continuously. All of the rats were randomly divided into allicin group and non-allicin group, each group was divided into three groups evenly, and put to death at 8, 16 and 24 weeks after medication separately. Large intestines were observed after dyeing. Results Large intestines were divided into ten equally, and all pieces were observed. ACF were almostly distributed in the middle and distal of the large intestines, about in 50%-80%.The basic situation of non-allicin group was as follows:ACF at 8 weeks was 63.97±1.22 on average per each, 16 weeks was 83.97±1.13, 24 weeks was 69.33±2.01. The basic situation of allicin group:ACF at 8 weeks was 9.4±1.12 on average per each , 16 weeks was 7.17±1.33, 24 weeks was 4.97±1.23.The occurrence of ACF in non-allicin group was higher than allicin group, the differences of incidence rate and number of ACF between two groups was significant (χ2=15.88,P<0.01).Conclusion Allicin can significantly reduce the number of ACF in Wister rats, lower the incidence of colorectal cancer, has prevention effect.

OBJECTIVETo observe the therapeutic effect of needle-pricking (NP) for treatment of anejaculation (AE), and its influences on sex hormone levels.

METHODSOne hundred and twenty-two AE patients were randomized into the treated group (62 patients) treated with NP applied mainly on bilateral points of sacral plexus and para-vertebra L1, every 5 days; and the control group (60 patients) treated orally with L-dopa and ephedrine 1 h before sexual intercourse. The therapeutic course for both was 45 days. Changes of clinical conditions and blood sex hormones levels were observed.

RESULTSThe total effective rate was 82.3% (51/62) in the treated group, which was significantly higher than that in the control group, 58.3% (35/60, P < 0.05); levels of luteinizing hormone (LH), follicular stimulating hormone (FSH) and estradiol (E2) were improved significantly in the treated group after treatment (P < 0.01), but in the control group no significant change of FSH was shown, and the improvement of LH and FSH was inferior to that in the treated group (P < 0.01).

CONCLUSIONNP could improve the clinical symptoms and adjust the blood levels of sex hormone in patients with AE, showing an effect better than L-dopa plus ephedrine in increasing LH and FSH levels.

Objective: To evaluate the short-term effect of thrombus aspiration catheters combining tiroifban medication for myocardial tissue reperfusion recovery in patients with acute ST-elevation myocardial infarction (STEMI).
Methods: A total of 105 STEMI patients with percutaneous coronary intervention (PCI) in our hospital from 2011-05 to 2013-05 were studied, there were 73 male and 32 female with the mean age of (58.39 ± 10.37) years. The patients were randomly divided into 2 groups, Group A, the patients received thrombus aspiration catheters with intravenous tiroifban, n=53 and Group B, the patients received tiroifban and PCI, n=52. The basic clinical features, myocardial tissue perfusion level, major adverse cardiovascular events (MACE) at post operative and in-hospital period were recorded, the cardiac function was examined by echocardiography at 6 months after PCI in both groups.
Results: The basic clinical features were similar between 2 groups. The thrombolysis in myocardial infarction trial (TIMI) 3 lfow rate was higher in Group A than that in Group B (92.45% vs 55.77%), P=0.000. TIMI 2 and TIMI 0~1 lfow rates were lower in Group A than that in Group B (7.55%vs 26.92%), P=0.008 and (0%vs 17.31%), P=0.002. The adjusted TIMI frame was lower in Group A (27.26±5.50) vs (38.98±5.42), P<0.001. The echocardiography at 6 months after PCI indicated that Group A had higher LVEF than that in Group B (0.55±0.06) vs (0.47±0.06), P<0.001;lower left ventricular end diastolic diameter (50.77±5.45) vs (54.76±5.34), P<0.001;less angina and target vessel revascularization (16.98%vs 40.38%), P=0.008 and (9.43%vs 17.31%), P=0.008. The incidence of MI, acute heart failure, cardiac death and non-target vessel revascularization were similar between 2 groups, P>0.05.
Conclusion:Thrombus aspiration catheters combining tiroifban medication may obviously improve the myocardial tissue reperfusion and the short-term cardiac function in STEMI patients after PCI, it could reduce the incidence of no-relfow without increasing MACE.

Objective To investigate cross-cultural differences in picture recognition memory of medical students. Methods Picture recognition memory were assessed by the classic new-old picture recognition,and behavioral results were recorded during the test. Results For new medical picture recognition, mean accuracy of Chinese medical students( 83.21 ± 8.95 )% was considerably higher than that of Indian medical students( 75.56 ±12.63)% (P＜0.05), while for old medical picture recognition, reaction time (RT) of Chinese medical students ( ( 887.57 ± 104.07 ) ms ) was longer than that of Indian medical students ( ( 840.93 ± 1 22.48 ) ms) (P＜0.05).Three way ANOVA suggested that cultural background and picture type significantly affected accuracy and RT,learning experience affected RT. In addition to picture type and learning experience, the interaction of each factors is not remarkable. Conclusion Cultural background, professional background and learning experiences have affected recognition memory. Medical students of different cultural background adopted difference strategies in picture recognition memory.

Objective To compare the event-related potential(ERP) difference waveforms between attention deficit hyperactivity disorder (ADHD) children and normal children in the conflict task,and to investigate the neural mechanism of conflict monitoring of ADHD. Methods ERPs elicited by performing the spatial SimonStroop task were recorded in 32 children with ADHD and 32 normal children. The differences of ERP and behavior dren with ADHD(0.80±0. 11 ,0.87 ±0.08) were less than normal children (0.88 ±0.07,0.93 ±0. 04)in Sireaction time of ADHD group( (773.03 ±99.34)ms) in the Siin were longer than the control group( (737.21 ±81.40)ms) ,the differences had statistic significance (P＜0. 05). 2. ERP results:the amplitude of N2 of the children with ADHD in the four conditions were smaller than the control group, the difference in Siin had statistic sigof prefrontal and anterior cingulate cortex of ADHD were weaker than the control group. Conclusions The results suggest that, due to the inadequate allocation of attention resources of the children with ADHD, they have conflict monitoring function defects compare with normal children. The function defects of conflict information processing related brain areas may be the main neural mechanism. The result of the behavior and ERP can become the reference indicator for the early diagnosis and treatment of ADHD.

Objective To report 11 cases with the tissue defects of their upper or lower limbs repaired with the anastomsed medial sural artery perforator flaps.Methods The free medial sural artery perforator flaps,with length of 8 cm to 15 cm and width of 6 cm to 14 cm were used for tissue defect reconstruction of the distal upper or lower limbs in 11 cases,including 6 females and 5 males.The flap was harvested from the ho- mo-lateral calf,confined between the posterior-medial edge of the tibia and the middle line of the calf and a- bove the distal half part of the medial sural muscle,with a same axis of this muscle.Results Ten cases survived very well,which was relatively thin,and the donor site can be acceptable.One case resulted in a complete flap necrotized and covered with a split skin graft.No obvious motor function defect was observed of the donor leg.Conclusion The anastomsed medial sural artery perforator flap is alternative donor flap for the upper or lower limb tissue defect repair,especially for the defect in the hand or foot.

Objective To investigate pathological mechanism of dysfunction of executive control in children with attention-deficit hyperactivity disorder (ADHD) ,using a new resting-state functional magnetic resonance imaging(fMRI) index, fractional amplitude of low frequency fluctuation (fALFF). Methods Thirty children of school age with ADHD and thirty gender, age and education-matched healthy controls were experienced restingstate fMRI scans. fALFF approach was used to analyze blood oxygen level-dependent fMRI(BOLD-fMRI) data in resting state. Results Compared with the normal controls,the ADHD showed decreased fALFF in the bilateral superior frontal gyrus( BA10, t=5. 40,4.11 ,Z =4.81,3.82),bilateral middle frontal gyrus( BA9,BA46, t=5.72,5.37, Z = 5.04,3.08 ), right medial frontal gyrus ( BA 10, t = 5.53, Z = 4.90 ) and left precuneus ( t = 3.81, Z =3.57). And the ADHD showed increased fALFF in the bilateral limbic lobe (BA36, t = 4.37,5.20, Z = 4.02,4.66 ), right brainstem ( t = 4.77, Z = 4.34) and bilateral cerebellum ( t = 4.65,4.83, Z = 4.24,4.38 ). Conclusion The results suggest that lower activition of frontal may be the core deficit of executive control with ADHD in resting state,and high activation in several brain regions may be related to compensatory effect.

Objective To evaluate the differential diagnostic value of 18F-FDG PET/CT between pancreatic lymphoma (PL) and pancreatic carcinoma (PC).Methods The 18 F-FDG PET-CT data of 16 patients who were pathological diagnosed with PL were retrospectively reviewed and compared with those of 32 consecutive pancreatic cancer patients who were pathologically diagnosed and randomly enrolled.The age,location,diameter and the maximum standard uptake values (SUVmax) of pancreatic lesions,pancreatic ductal dilatation,distal pancreatic atrophy,serum CA19-9 level and extrapancreatic organs involvement were analyzed.Results The 16 patients with PL included 8 men and 8 women,the mean age was (46 ± 17)year,and 11.1％ (1/9) patients had elevated CA19-9.The 32 patients with PC included 15 men and 17 women,the mean age was (61 ± 12)year,and 81.3％ patients had elevated CA19-9.There were no significant differences on gender between the two groups,while the mean age of PL patients was younger than that of PC,elevated CA19-9 was less common than that in PC,and the differences were statistically significant (all P＜0.05).There were 12 cases of diffusive large B cell lymphoma,2 cases of B lymphoblastic lymphoma/leukaemia,1 case of follicular lymphoma and 1 case of dysplastic large T cell lymphoma in 16 PL patients.There was no significant difference on the site of pancreatic lesions between the two groups,but long diameter of PL lesions was larger than that of PC [(6.6 ± 3.3) vs (4.3 ± 1.8) cm,P =0.038].Dilated pancreatic duct and distal parenchyma atrophy in PL were less than those in PC (3/16 vs 17/32,1/16 vs 13/32),and SUVmax of PL lesions was significantly higher than that of PC (12.0 ± 5.5 vs 8.6 ± 3.8),indicating that the differences were statistically significant (all P ＜ 0.05).The cut-off value of SUVmax was 9.95,and Youden's index was 0.406 with the sensitivity and specificity of 68.8％ and 71.9％ for differentiating PL from PC.The incidence of extrapancreatic lesions including bone marrow and kidney and spleen infiltration was significantly more frequent in patients with PL than that in patients with PC(56.3％ vs 6.25％,43.8％ vs 3.1％,50.0％ vs 6.3％),while the incidence of liver metastases was significantly lower than that in PC (12.5％ vs 5.0％),indicating that the differences were statistically significant (all P ＜0.01).There were no significant differences on the incidence of other extrapancreatic lesions.Conclusions PL should be considered in relatively younger patients and manifested as a bulky mass with significant FDG uptake and extrapancreatic involvement of bone,kidney and spleen but without distinct pancreatic ductal dilation or distal parenchymal atrophy or liver metastasis.
