Objective:To investigate the efficacy and safety of different doses of tirofiban combined with coronary artery intervention in treatment of Non ST-segment elevation acute coronary syndromes (NST-ASC).Methods:110 cases with NST-ACS from October 2014 to January 2016 in our hospital were chosen and divided into the all dose group and half dose group.The TIMI blood grade before and after treatment,cardiac function before and after treatment for 30 d,major adverse cardiac events and bleeding events,hospitalization expenses and hospitalization days were recorded and compared between two groups.Results:Compared with before treatment,the TIMI 2 grade and 3 grade were obvious decreased,and the left ventricular end diastolic volume (LVEDV),left ventricular end systolic volume (LVESV) after treatment for 30 d were all obvious decreased,while the left ventricular ejection fraction (LVEF) were significant increased,P＜0.05.And the TIMI blood flow grading,LVEDV,LVESV and LVEF before and after treatment in two groups had no significant difference (P＞0.05),and the major adverse cardiac events and hospitalization days of two groups had no significant difference,P＞0.05.While the bleeding events and hospitalization expense of all dose group was obvious higher than those of half dose group,P＜0.05.Conclusions:The half dose group of tirofiban combined with coronary artery intervention in treatment NST-ACS has obvious efficacy,it can decrease the bleeding events and hospitalization expense.

OBJECTIVETo apply the Wright-Giemsa stain in micronucleus test and to explore the stain outcomes of Wright-Giemsa dye of various proportions and staining times.

METHODSUse Wright-Giemsa dye, Wright dye (staining time 3 min) and Giemsa dye (staining time 5 min) to stain HepG2 and then observe the staining effect. The Wright-Giemsa dye was applied under 5 different proportions (3:1-1:3) and different staining times (1, 3, 5, 10, 15 min).

RESULTSAfter stained for 3-5 min with the proportion ratio of 3:1 of Wright-Giemsa dye, the HepG2 cells showed much better staining outcomes compared with the single stain of either Wright or Giemsa.

CONCLUSIONSWright-Giemsa stain can be used in cell micronucleus test to obtain good staining outcomes.

One hundred and eighty three women with high risk of breast cancer identified in Baoding First Central Hospital from June 2007 to June 2014,were enrolled in the study.In these 183 cases,41 received preventive therapy (22.4％),142 did not.Factors associated with acceptance of chemoprevention included older age,menopause,comorbidities,lower level education,being married,higher BMI,having high level hyperplasia of ductal epthelia and counseling to breast specialists (P ＜ O.05);whilenot informed by doctors was the main reason for failed taking preventive agents(95.1％,135/142).Thirteen of 41 women receiving chemoprevention discontinued the therapy (31.7％);no-insurance,no side-effects and higher BMI were related to the discontinuing (P ＜ 0.05).The 1-,2-,3-,and 5-year adherence rates of chemoprevention was 86.1％ (31/36),65.4％ (17/26),59.1％ (13/22),8/13 and 5/10,respectively.The results show that chemoprevention rate is low among Chinese women at high risk of breast cancer,and the long-term adherence to preventive therapy is poor.Corresponding measures should be taken to strengthen the chemoprevention of breast cancer.

Objective To observe the oral part of the facial artery and facial vein and to provide anatomical data for clinical applica-tion. Methods The origin, branches, course, diameter, position of oral part of facial artery and facial vein were observed on 32 fixed cada-ves (64 sides). Results The position relation between the facial artery and facial vein is non-constant. Measure the distance from inferior border of mandible to corner of the mouth, angulus mandibulae, mental protuberance midpoint. It is (5. 49 ± 0. 63) cm, (2. 50 ± 0. 89) cm and (6. 20 ± 1. 68) cm in the left side respectively, and (5. 69 ± 0. 72) cm, (2. 56 ± 1. 08) cm and (6. 85 ± 1. 86) cm in the right side re-spectively. The diameter of facial artery in inferior border of mandible is (0. 33 ± 0. 08) cm in the left side and (0. 38 ± 0. 07) cm in the right side;while the diameter of facial vein is (0. 40 ± 0. 12) cm in the left side and (0. 42 ± 0. 18) cm in the right side. The facial artery and facial vein are not concomitant and they are not asymmetry also. The position of superior labial artery arteries is constant, but the position of inferior labial artery arteries have more variations. Conclusion The branches, course, diameter and position of oral part of facial artery and facial vein have a number of variations. The superior labial artery arteries could be positioned more easily than inferior labial artery arter-ies. Being familiar with their distribution is of great importance for clinical application.

Aim To evaluate the efficacy of the combination of leonurine(SCM),polygonatum polysaccharide(PSP)and deoxynojirimycin(DNJ)in hypoglycemic and antithrombotic aspects by establishing and using zebrafish type II diabetes combined with thrombosis model. Methods On the basis of the zebrafish type II diabetes model established by streptozotocin,phenylhydrazine(PH),arachidonic acid(AA)and ponatinib(PT)were used respectively to establish thrombosis models,which were divided into control group,model group,metformin+aspirin group,and the high,medium and low concentration groups of the combination drugs. After drug intervention in the experimental group,the thrombosis of tail vein was observed. Kit was used to determine the sugar content of juvenile fish tissues in each group. Quantitative analysis of cardiac erythrocytes by o-dianisidine staining method was used to calculate the inhibition rate of thrombus. Quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the mRNA expressions of related genes in zebrafish. Results Compared with the model group,the combined drug could significantly increase the staining intensity of erythrocytes in zebrafish hearts,inhibit thrombosis,down-regulate the expression of thrombosis-related genes,and reduce tissue glucose content. Conclusions The combined use of the three drugs can effectively reduce the tissue sugar content and have antithrombotic effect,which show great potential in the development of drugs for the treatment of type II diabetes and thrombosis.

Objective:To analyze the clinical and pathological features and gene mutations of pancreatic acinar cell carcinoma (PACC).Methods:Clinical data of 34 patients with PACC admitted to the Department of Pancreatic Surgery of the First Affiliated Hospital of Naval Medical University from December 2009 to July 2018 were retrospectively analyzed to summarize its clinical characteristics, and the expressions of α1-ACT, CaM5.2, Syn and CgA in pancreatic tumor tissues were detected by immunohistochemistry. Next-generation gene sequencing technology was used to detect gene mutations in tumor specimens.Results:Among the 34 PACC patients, 23(68%) were males and 11(32%) were females; the age ranged from 25 to 75 years, with an average age of 54 years. The first symptom was abdominal pain or distension in 21 cases (62%), skin or scleral yellow staining in 4 cases(12%), and 9 cases(26%) were found in routine physical examination. BMI was 17.6-34.0 kg/m 2, of which 3 cases (9%) were <18.5 kg/m 2, 23 cases (68%) were 18.5-24.0 kg/m 2, and 8 cases (23%) were >24.0 kg/m 2. Preoperative examination showed elevated CA19-9 in 7 cases (20.6%), elevated CEA in 3 cases (8.8%), and elevated AFP in 7 cases (20.6%). Blood amylase was 16-247 U/L, with an average of 80 U/L. Enhanced CT showed that the lesion was irregular in shape, showing inhomogeneity and slightly low density, with areas of cystic degeneration and necrosis. The tumor was located in the head of the pancreas in 14 cases (41%), the body and tail of the pancreas in 19 cases (56%), and the neck of the pancreas in 1 case (3%). The largest tumor diameter was 1.5-15.5 cm, with an average of 5.4 cm. Postoperative pathologic stage I was confirmed in 4 cases (12%), stage Ⅱ in 14 cases (41%), stage Ⅲ in 14 cases (41%) and stage Ⅳ in 2 cases (6%). Immunohistochemical results showed that both α1-ACT and CaM5.2 were positively expressed (100%). Syn was positive in 8 cases (23.5%) and CgA was positive in 6 cases (17.6%). Ki-67 index was from 9% to 70%, with an average of 41%. Gene sequencing of pancreatic tumor tissue from 6 patients showed BRCA2 mutation in 2 patients (7155C>G), K-ras mutation in 1 patient (35G>T), RET mutation in 1 patient (200G>A), and LKB1 mutation (234G>T) in 1 patient, and one double mutation of K-ras and RET (35G>A, 1 798C>T). 30 patients were followed up, and the median survival was 38.3 months. Conclusions:PACC was a rare pancreatic tumor with no specific clinical manifestations. The positive expression rates of α1-ACT and CAM5.2 in tumor tissues were 100%. BRCA2, K-ras, RET and LKB1 were common gene mutations.
