Objective To analysis newborn stage and long-term physiological and neuropsychological development in children born after assisted reproductive technology(ART),and to evaluate the safety of ART.Methods Eighty-four 6-month-old to 6-year-old children born after ART performed from January 1st,2006 to June 30th,2011 in Reproduction Center of Fuzhou General Hospital were taken as ART group; and 84 matched children born after spontaneous conception were as control group.The physiological and neuropsychological states of these children in their newborn stage and 6-month-old to 6-year-old duration were compared with Chi-square or t test.Results There was no statistical difference in childbearing age of mothers,the prevalence of gestational diabetes mellitus and hypcrtensive disorder complicating pregnancy,delivery mode,living environment,parents' education level,newborn birth length,birth weight,the rate of premature birth,low birth weight,asphyxia and hospitalized to neonatal intensive care unit between two groups (P＞0.05).In ART group,the incidence of growth retardation and abnormal social life skills was 6.0 ％ (5/84) and 1.2 ％ (1/84),and no statistical difference were found comparing with control guoup [4.8％(4/84) and 1.2％(1/84),x2 =0.12 and 0.00,P＞0.05],neither the developmental quotient (95.9±6.1 vs 94.8±5.1,t=1.25,P=0.21).Twins had higher rates of preterm birth [41.8％ (33/79) vs 10.1％(9/89),x2 =22.37,OR=6.38,95％CI:2.81-14.50,P=0.00],low birth weight [51.9％(41/79) vs 6.7％(6/89),x2=42.35,OR=14.93,95％ CI:5.84-38.16,P=0.00],asphyxia [10.1 ％ (8/79) vs 1.1 ％(1/89),x2 =6.69,OR=9.92,95％ CI:1.21～81.15,P=0.01],hospitalized to neonatal intensive care unit [36.7 ％ (29/79) vs 14.6 ％ (13/89),x2 =10.90,OR =3.39,95％CI:1.61-7.14,P=0.00] and growth retardation [11.4％(9/79) vs 0.0％(0/89),x2=10.71,RR=0.11,P=0.00] than singleton.Conclusions ART has no negative effects on children's physical and neuropsychological development.It could increase the incidence of twins,so that it might increase the incidences of preterm labor and low birth weight,which might affect the long-term physical and neuropsychological development of the offspring.

Dermoid cysts occur in the maxillary sinus mucosa were rare. Patient's CT showed: maxillary sinuses Sinus cavity expansion, sinus wall thinning. The inside of the sinus wall disappeared, the maxillary sinus filled with soft tissue mass shadow. Bacterial culture: Staphylococcus aureus. Pathological report: a very small a mount of scattered broken squamous epithelium and keratosis, no atypia cells. Lesions consistent with epidermoid cyst. Patients with epidermoid cysts, formated probably in the process of embryonic development, the reasons of rapid growth may be considered for inflammatory stimulation.

BACKGROUND:With the development of AO, the treatment of intercondylar humeral fractures with open reduction has been a trend. However, the methods of fixation become many. There is no conclusion of which method is optimal.
OBJECTIVE:To investigate the clinical effect of two kinds of different fixation methods (Y-type steel plate and double steel plate) for intercondylar humeral fractures via different surgical approaches.
METHODA retrospective analysis of clinical data of 86 cases of fresh intercondylar humeral fractures in the Department of Orthopedics, Sixth Affiliated Hospital, Xinjiang Medical University, between December 2003
and May 2014 were conducted in this study. According to the different fixation materials, patients were divided into two groupdouble steel group (n=44, including the surgical approach of ulna olecranon osteotomy which had 22 cases and the surgical approach of triceps V shaped severance which had 22 cases), Y-type steel group (n=42, including the surgical approach of ulna olecranon osteotomy which had 21 cases and the surgical approach of triceps V shaped severance which had 21 cases). The clinical curative effect and related complications of the two groups after operation were analyzed. During fol ow-up, modified Cassebaum elbow scoring system was used to evaluate the excellent and good rate of therapy.
RESULTS AND CONCLUSION:After fol owed up for 12-36 months, the total excellent and good rate of Y-type steel plate was 76%and the total excellent and good rate of double steel plate was 77%. There were no significant differences between the two groups (P>0.05). But interestingly, the surgical approach of ulna olecranon osteotomy was better than the surgical approach of triceps V shaped severance and the difference was statistical y significant (P<0.05). Above data suggested that Y-type steel plate and double steel plate were effective ways in the repair of intercondylar humeral fractures. However, for different surgical approaches, the surgical approach of ulna olecranon osteotomy was better than the surgical approach of triceps V shaped severance.

Objective: To compare therapeutic effects of clopidogrel and loading dose ticagrelor on aged patients with ST elevation myocardial infarction (STEMI).Methods: A total of 160 aged STEMI patients undergoing emergency percutaneous coronary intervention (PCI) were selected.According to random number table, they were randomly and equally divided into clopidogrel group (received loading dose aspirin and clopidogrel therapy) and ticagrelor group (received loading dose aspirin and ticagrelor therapy).Coronary TIMI flow grade, incidence rate of no-reflow after PCI, and incidence of cardiac adverse events and bleeding events in one month after PCI were compared between two groups.Results: Compared with clopidogrel group after PCI, there was significant rise in percentage of coronary TIMI flow grade 3 (71.25% vs.90.00%), and significant reduction in incidence rate of no-reflow (28.75% vs.10.00%) in ticagrelor group,P<0.05 all.Compared with clopidogrel group on one month after PCI, there were significant reductions in incidence rates of cardiogenic death (13.75% vs.3.75%), in-stent thrombosis (6.25% vs.0) and recurrent myocardial infarction (10.00% vs.1.25%), but significant rise in incidence rate of dyspnea (3.75% vs.12.50%) in ticagrelor group, P<0.05 all.There was no significant difference in incidence of bleeding events between two groups, P>0.05 all.Conclusion: Loading dose ticagrelor can effectively improve coronary blood flow, reduce no-reflow and its safety is good in aged patients with ST elevation myocardial infarction, which is worth extending.

[Summary]_ Severe hypertriglyceridemia is the third common cause of acute pancreatitis following after alcohol abuse and cholelithiasis. Moreover, it is also an important risk factor of cardiovascular events. However, the cases of severe hypertriglyceridemia caused by autoimmune disease were rare in clinical, which would bring the difficulty for diagnosis and treatment. A better understanding of the clinical characteristics, possible pathogenesis, and corresponding therapy of the disease would be helpful, which would reduce the risk of complications, and finally improve both the survival rate as well as quality of life of these patients.

Objective: To explore assessment value of heart rate variability (HRV) of Holter for cardiac autonomic nervous function in patients with acute stroke.Methods: A total of 80 cases with acute stroke treated in our hospital were regarded as stroke group, and another 80 inpatients without cardio-and cerebrovascular diseases were enrolled as control group simultaneously.Holter was used to perform 24h ambulatory heart rate monitoring on two groups, and the results were compared between two groups.Results: Compared with control group, there were significant reductions in standard deviation of normal to normal RR intervals calculated over the 24 h period [SDNN, (129.89±5.42) ms vs.(92.58±4.36) ms], standard deviation of normal to normal RR intervals in all 5 min segments of the entire recording [SDANN, (118.85±5.79) ms vs.(77.36±4.82) ms], root-mean square of differences between successive normal to normal intervals [rMSSD, (27.04±1.18) ms vs.(7.31±1.09) ms] and adjacent normal RR interval difference >50ms stroke accounted for a percentage of 24h total RR interval [PNN50, (8.97±1.48)% vs.(2.62±0.54)%] in stroke group, P<0.01 all;in stroke patients, there were no significant difference in above indexes between cerebral infarction patients and cerebral hemorrhage patients, P>0.05 all.Conclusion: HRV indexes possess significant assessment value for cardiac autonomic nervous function in patients with acute stroke.They can predict patient′s status changes, and help to prevent and identify severe cerebrovascular disease in time.
