Objective To observe the clinical efficacy and safety of ticagrelor tablets combined with aspirin tablets in patients with ST-segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI) . Methods A total of 426 patients with STEMI treated with PCI were randomly divided into control and treatment groups with 213 cases per group. Control group was orally given the loading dose of clopidogrel 600 mg + aspirin 300 mg before PCI, followed by oral clopidogrel 75 mg per time, qd + aspirin 100 mg per time, qd, after operation. Treatment group was given orally ticagrelor with the loading dose of 180 mg + aspirin 300 mg before PCI, followed ticagrelor 90 mg per time orally, bid + aspirin 100 mg per time, qd, after operation.Two groups were treated for 30 days. The red blood cell distribution width (RDW) , neutrophil/lymphocyte ratio (NLR) , platelet/lymphocyte ratio (PLR) and adverse drug reactions were compared between two groups. Results After PCI 30 days, the main indexes of treatment and control groups were compared: RDW were (14. 85 ± 0. 95) ％ and (11. 48 ± 1. 43) ％, NLR were (2. 98 ± 0. 98) ％ and (2. 09 ± 1. 68) ％, PLR were (120. 34 ± 13. 88) ％ and (131. 36 ± 12. 96) ％, the differences were statistically significant (all P < 0. 05) . The adverse drug reactions of treatment group were dizziness, gastrointestinal bleeding and serum creatinine rise, which in control group were diarrhea, gastrointestinal bleeding, headache, nausea and vomiting. The total incidences of adverse drug reactions in the treatment and control groups were 5. 16％ and9. 86％ with significant difference (P < 0. 05) . Conclusion Ticagrelor tablets combined with aspirin tablets have a definitive clinical efficacy and safety in the treatment of patients with STEMI treated with PCI.

Objective: To investigate the incidence of CMV infection(CMV-I) and CMV related diseases (CMV-D) after allogeneic hematopoietic stem cells transplantation in 70 consecutive allogeneic hematopoietic stem cells transplantation(allo-HSCT) patients and to search for the optimal prophylactic strategy.Methods: Blood samples were monitored using the CMV pp65 antigenemia assay.Of the 70 patients observed,30 patients with chronic myeloid leukemia［CML:CP(27),AP(2),BC(1)］,12 with acute myeloblastic leukemia(AML),10 with acute lymphoblastic leukemia(ALL)and other cases were NHL(3), AA(5), MDS(7), SCLC with pancytopenia (1),CLL(1), and MF (1). Sixty six patients received HLA - identical siblings transplantation and four received tranplants from their HLA- haploidentical donors. Seventy cases included allo-PBPCT (64 cases) , allo-BMT (4 cases) and allo-PB+BMT (2). Before transplantation, all patients and donors received CMV serological examination except 4 pairs of donors/recepients. All 66 patients (3 cases were CMV IgM positive) and 64/66 donors were CMV IgG positive. Results：After transplantation, 64/70 patients developed CMV viremia during monitoring period. Forty three of 70 patients developed CMV-D.Thirty five of them suffered from CMV-associated interstitial pneumonia(CMV-IP). The high peak levels of CMV antigenemia were associated with development of CMV disease　. Close correlation was found between acute graft vs host disease(GVHD) and CMV disease. The patients were followed up for 2 to 24 months. The patients who received preemptive therapy(group A)had significantly better outcome than CMV disease group(group B, P=0.0001). Conclusions: The results suggest that CMV antigenemia has high predictive value for subsequent CMV disease and CMV pp65 antigenemia -guided early therapy has particular advantage for avoiding morbidity and mortality caused by CMV disease.

OBJECTIVETo study the association of beta-fibrinogen(Fg) gene -148 C/T and 448 G/A polymorphisms, plasma Fg concentration, molecular reactivity and the type of cerebral infarction.

METHODSGene polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism. The plasma Fg concentration and the molecular reactivity were also determined.

RESULTSThe Fg concentration in MCI patients with T -148 allele was higher than that in PCI patients and controls. The MCI patients with A448 allele had higher Fg concentration, FMPV and FMPV/Amax when compared with controls, and had higher FMPV/Amax when compared with PCI patients.

CONCLUSIONFgB beta -148 and 448 mutational genotypes have impact on Fg concentrationì and therefore increase the risk of MCI.

OBJECTIVETo investigate the correlation between lifestyle factors, parental obesity and adiposity in children, in order to provide theoretical evidence for public health policy establishment.

METHODSA cross-sectional observation study was conducted among approximately 20 thousand children aged 2 - 18 years old in urban and rural regions of Beijing, by using stratified randomization clustering sampling methods. Familial environmental risk factors of children adiposity and parental obesity were assessed with standardized questionnaire. Anthropometric measurements, including height and weight, were conducted. SPSS 13.0 software was applied to analyze the data, including general description, chi(2) trend test and non-condition logistic analyse.

RESULTSWith IOTF obesity references, the prevalence of obesity in 21,198 children aged 2 - 18 years old was 5.6%. The behavioral characters (for example, smoking and drinking) and children obesity showed significant familial aggregation. In groups including "both parents not smoke", "only one parent smoke" and "both parents smoke", the smoking rates of offsprings were 1.50%, 2.93% and 6.01%, respectively (chi(trend)(2) = 107.009, P < 0.01). A similar pattern was found for offsprings' alcohol consumption rates (5.85%, 9.12% and 13.96%; chi(trend)(2) = 107.009, P < 0.01). Based on parents' BMI status, in groups including "both parents had normal weight", "father was obese", "mother was obese" and "both parents were obese", the prevalence of obesity in children were 3.29%, 11.48%, 9.12% and 27.01%, respectively (chi(trend)(2) = 293.404, P < 0.01). After controlling for sex and ages, factors such as physical exercises, sleeping times per day, fat intakes, watching TV, drinking alcohol were impact factors of children obesity. After controlling of confounding factors, such as children gender, age, birth weight, puberty, smoking history, drinking history, fat intakes, soft drink, physical exercises, education experiences of parents, smoking history, drinking history, family income and so on, maternal obesity had a greater influence on daughters than on sons (OR = 5.93, 95% CI: 3.57 - 9.84), and paternal obesity showed similar influence on sons (OR = 4.29, 95% CI: 3.21 - 5.72). Comparing to parents with normal weight, obese parents had more powerful impact on daughters (OR = 28.51, 95% CI: 15.13 - 53.72) than on sons (OR = 7.21, 95% CI: 4.07 - 12.75), regarding to 2 - 5 years group and 10 - 12 years group versus other age group (OR = 18.67, 95% CI: 1.49 - 234.46; OR = 22.25, 95% CI: 10.62 - 46.59).

CONCLUSIONParental obesity is an independent risk factor of adiposity in children; gender and age affect this association. The lifestyle patterns of parents should have great impact on children. When prevention or intervention with children obesity, familial environmental factors should be emphasized.

AIM: To investigate the curative effect of phacoemulsification and intraocular lens ( IOL ) implantation combined with goniosynechialysis in the treatment of age-related cataract merging with primary angle-closure glaucoma ( PACG) . · METHODS: Totally 80 patients with age-related cataract merging with PACG were in our hospital from January 2014 to January 2016. The preoperative average intraocular pressure ( IOP) was 33. 22 ± 3. 17mmHg; the average depth of anterior chamber was 2. 07 ± 0. 15mm;the dynamic situation of primary angle closure ≤1/2 cycle by gonioscope. They were randomly divided into Group A and B for doing a study. All the two groups were treated with phacoemulsification and intraocular lens implantation. And the Group A was with goniosynechialysis. The following up period was 2mo, and we observed the IOP, chamber depth and the anterior chamber angle. · RESULTS: The change of chamber depth and intraocular pressure about the two groups: the average intraocular pressure of the Group A was 15. 11 ± 3. 67mmHg,the chamber depth was 3. 11±0. 08mm;those of the Group B were 17. 24 ± 1. 67mmHg, 2. 76 ± 0. 15mm respectively; the differences had statistical significance (P<0. 05). Postoperatively, there were 28 eyes (70%) in Group A with fully open anterior chamber angle, and 18 eyes (45%) in Group B (P<0. 05). · CONCLUSION: The phacoemulsification and intraocular lens implantation combined with goniosynechialysis in the treatment of age-related cataract merging with primary angle-dosure glaucoma is safe and reliable. It's simple to operate, and do not increase the risk of surgery.

Objective To classify and grade the environments with Oncomelania hupensis snails inside embankment in marsh-land and lake areas,so as to improve the work efficiency and realize the systematic management. Methods The schistosomiasis endemic area Liaodi and Xiongdi villages in Jiangling County,Hubei Province were selected as the experiment villages,and the environments with snails in the two villages were divided into sections with a length of 500m,then the snail situation were sur-veyed by the systematic sampling method with 10m and 50m a frame respectively. The environments were classified according to the discovery of infected snails and wild fecal contamination,and the numbers of sites with snails and their areas in different class-es were recorded. Meanwhile,the data of sites with infected snails in Jingzhou City during the recent 5 years were collected and graded according to the average density of snails,so as to discuss the correlativity between the grades of environments with snails and the numbers of sites with infected snails and the occurrence rate of frames with snails. Results There were 1 967 sites with in-fected snails in Jingzhou City during the recent 5 years,and there was a positive correlation between the grades of environments with snails and the occurrence rate of frames with snails(rs=0.77,P<0.01),when the grade was 5,the constituent ratio of num-bers of sites with infected snails was 3.1%,and when the grade was 2-3,the ratio raised to 56.3%. There were 39 sites with snails in the two villages,the Class 1,2 and 3 environments included 1,18 and 20 sites,with the areas of 1 080,51 640 m2 and 41 220 m2 , respectively. There were no statistically significant difference between the grades divided by snail survey with 10m and 50m a frame(χ2=4.667,P>0.05),but the time-consuming of the former was 3 times of the latter. Conclusions The classification and grading of the environments with snails inside embankment in marshland and lake areas can master the key point of the snail survey. The subsection and setting frames at a suitable distance can save time and manpower,improve work efficiency,as well as understand the distribution of snail status of the environment with snails,which can realize the sort management of the snail envi-ronments inside embankment.

The effects of femoral nerve electrostimulation (FNES) on ischemia-reperfused myocardium were examined in the urethane- anesthetized rats to determine whether FNES may provide cardioprotection and to observe the possible mechanism. The area at risk (AR) and infarct area (IA) were determined using Evans blue and nitro-blue tetrazolium staining, respectively. Infarct size (IS) was defined as 100xIA/AR (%). The results are as follows: (1) During 30 min myocardial ischemia and subsequent 120 min reperfusion, the myocardial infarct size occupied (54.96+/-0.82)% of the area at risk. (2) FNES of high frequency (10 V, 100 Hz, 1 ms) significantly reduced myocardial infarct size to (36.94+/-1.34)% (P<0.01), indicating the cardioprotective effect FNES of high frequency on myocardial ischemia-reperfusion, while FNES of low frequency (10 V, 10 Hz, 1 ms) had no effect on myocardial infarct size. (3) Pretreatment with either naloxone (5 mg /kg, i.v), a nonselective opioid receptor antagonist, or glibenclamide (5 mg /kg, i.v), a K(ATP) channel antagonist, completely abolished the cardioprotection of FNES (100 Hz) from myocardial ischemia-reperfusion. It is suggested that FNES of high frequency can protect myocardium from ischemia-reperfusion injury. The possible mechanism is that FNES of high frequency may induce the release of opioids from the central nervous system, and the activation of opioid receptors in the heart results in an opening of myocardial K(ATP) channels which can protect myocardium.

OBJECTIVETo explore the mechanism of 'erythroblast island (EI)' formation in the bone marrow of patients with immun-related hemocytopenia (IRP).

METHODSThe category of BM-auto antibody (au Ab) in 48 patients with IRP was detected with FCM. The BM-au Ab in the 'EI' of these cases were explored with immuonhistofluorescence (IF). Clinical and laboratory characteristics of these cases were also analyzed retrospectively.

RESULTSIgG could be detected in the 'EI' on the BM smear of 14 cases (29.17%), BM-au Ab mainly deposited at the edge/membranes between macrophage and erythroblasts rather than cyto plasm. Positive reaction were seen in all the cases with GlycoAIgG. The red blood cell count [(1.8 ± 0.5) × 10(12)/L] and hemoglobin level [(59.6 ± 16.2)g/L] were significantly lower than that in the IF(-) group [(2.5 ± 0.9) × 10(12)/L and (83.4 ± 25.0) g/L] (P < 0.05). The percentage of reticulocyte [(2.0 ± 0.8)%], serum level of IBIL [(9.4 ± 4.7) µmol/L], percentage of erythroblats in sternum BM (0.441 ± 0.139) and response rate to therapy (85.7%) in IF(+) group were significantly higher than that in IF(-)group [(1.3 ± 1.0)%, (6.6 ± 6.7)µmol/L, 0.298 ± 0.082, 61.3%, respectively] (P < 0.05).

CONCLUSIONMacrophage was connected with erythroblasts through autologous IgG in the 'EI's of some patients with IRP. 'EI' were the places where macrophages devoured and destroyed erythroblasts rather than erythroid development and differentiation. The pathogenetic mechanism of IRP might be associated with macrophages phagocytosing and destroying BM hematopoietic cells.
