AIMTo evaluate the effects of atria-His bundle sequential pacing on cardiac electrophysiology and heamodynamics in dogs.

METHODSIn 20 opening chest anesthetized dogs, platinum electrodes were fixed at the epicardium of right atria (RA) and the right ventricular apex (RVA) respectively, pacing right atria and the right ventricle. A special lead was located at His bundle (based on a optical "H" wave and narrow duration of the QRS complexes recorded in ECG), pacing His bundle. Cardiac electrophysiology and hemodynamics parameters were compared in the different pacing models RA(AAI, RVA-(VVI), HisB-(VVI) single chamber pacing and RA-RVA(DDI), RA-HisB(DDI) dual chamber pacing.

RESULTSThe threshold of His B pacing is similar to that of RVA pacing. Cardiac output (CO) is increased in pacing of RA(AAI), His B-(VVI) and RA-His B(DDI). It is increased by 29.64% in pacing of RA-His B(DDI) (P < 0.01) and by 0.25% (P > 0.05) in pacing of RA-RVA(DD1) While CO is decreased by 5.41% in RVA-VVI) pacing (P > 0.05). SV, LVSW and RVSW of RA-HisB(DDI) pacing are superior to those in RVA-VVI) and RA-RVA(DDI) pacing.

CONCLUSIONRight atria-His bundle sequence pacing significantly improves cardiac function compared with the other model pacing because it maintains normal physiological electronic activity sequence and systolic synchrony. It will be adapted to clinical application.

OBJECTIVETo investigate the clinical effects and operative options for the treatment of Forestier disease.

METHODSFrom June 2005 to May 2012, 8 patients with progressive dysphagia due to Forestier disease were treated through anterior approach, their clinical data were retrospective analyzed. There were 6 males and 2 females, aged from 65 to 83 years old with an average of 73 years. Among the patients, osteophytes removal was performed in 3 cases, osteophytes removal with discectomy and fusion was performed in 2 cases, osteophytes removal with corpectomy and fusion was performed in 3 cases. According to Bazaz dysphagia score to assess the improvement of the patients' symptoms before and after operation.

RESULTSAll patients were followed up from 12 to 40 months with the mean of 18.5 months. Seven cases were asymptomatic and 1 case had mild symptom in the last follow-up. Radiographs showed the space enlargement between vertebral body and trachea.

CONCLUSIONIt is effective to treat patients with progressive dysphagia due to Forestier disease through surgical method. And the operative options depend on the stability of cervical spine and the neurological symptoms of the patients.

This study aimed to study the epidemiological and clinical characteristics of human bocavirus 1-4 (HBoV1-4) in children with acute diarrhea in Lanzhou and to investigate the association between HBoV and acute gastroenteritis. A total of 331 stool samples were collected from children aged under 5 years with acute diarrhea at the Department of Pediatrics, the First Hospital, Lanzhou University, between July 2012 and June 2013. Nested PCR was used to screen for HBoV and a general PCR was employed to screen other common diarrhea viruses. We found human bocavirus 1, 2, 3 and 4 in 26, 15, 7 and 1 cases, respectively. There was no specific seasonal distribution of HBoV, with infections occurring throughout the year. HBoV was mostly found in children aged between 7 and 12 months, with a mean age of 11.04 months (+/- 6.92 months), and 93.88% of affected children were aged under 2 years. Overall, 71.3% of mixed infections were mixed and the majority of other infections were caused by rotavirus. There was no statistical difference in the incidence of fever and vomiting associated with HBoV infection. A rare virus strain, HBoV4 (LZFB086), was identified, which showed highest levels of nucleotide sequence identity (99.0%) with a single Thai HBoV strain (JQ267789). No case of HBoV2B was found. In conclusion, HBoV1 was a major etiological pathogen of HBoV in pediatric cases in Lanzhou. HBoV4 was detected in feces for the first time in China. The rate of mixed infections was high and rotavirus was dominant. The data presented suggests that HBoV is not a major causative agent of gastroenteritis.

OBJECTIVETo explore the association between genetic polymorphism of serum amyloid protein A1 (SAA1) with carotid intima media thickness in a healthy Han Chinese population of Xinjiang.

METHODSA total of 449 healthy Han Chinese participating the cardiovascular risk survey between June 2007 and September 2009 were included, the genotypes of the SAA1 were detected by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). The mean IMT of the right and left common carotid arteries were measured by B-mode ultrasonography.

RESULTS(1) There was strong linkage disequilibrium between rs12218 and rs2229338 (D' = 0.89). (2) The carotid common IMT (CC-IMT) and the carotid bulb IMT (CB-IMT) were similar between the AA genotype (wild genotype) and the GGFAG genotype (mutational genotype) in rs2229338 of SAA1 gene. (3) CC-IMT [(0.081 ± 0.071) cm vs (0.068 ± 0.019) cm, P = 0.01] was significantly thicker in CC + CT genotype (mutational genotype) group than in TT genotype (wild genotype) of rs12218 group and the difference remains significant after adjustment for age, gender, blood pressure, waist circumference, creatinine and high density lipoprotein cholesterol. CB-IMT [(0.085 ± 0.038) cm vs. (0.081 ± 0.052) cm, P = 0.36] was similar between CC + CT genotype and TT genotype of rs12218 groups.

CONCLUSIONOur results suggested that the genetic polymorphism of SAA1 might be linked with IMT and rs12218 mutation could serve as a promoting factor for IMT in Han Chinese people.

From January 2013 to January 2015, 19 patients of traumatic hemothorax with hemorrhagic shock were treated in our department by thoracoscopic surgery combined with autologous blood transfusion. This study retrospectively analyzed the therapeutic effect and shared our experience. The average amount of blood transfused back was 662.41 ml ± 269.15 ml. None of the patients developed transfusion reaction and were all discharged uneventfully. Thoracoscopic surgery combined with autologous blood trans- fusion is effective in the rescue of patients with progressive hemothorax and hemorrhagic shock. When corresponding indications are well managed, treatment for these patients is quicker, safer, and more effective.

Objective To investigate the prevalence and epidemiological features of valvular heart disease (VHD)adult populations with different ethnicities in Xinjiang.Methods A total of 14 618 adults aged 35 or older were surveyed.Random sampling was employed to study valvular heart diseases in different age,gender and ethnic groups.Samples were collected fiom 7 localities (Urumqi,Ke lamayi,Fukang,Turfan Basin,Hetian,Altay,Yili Hazakh Autonomous Prefecture) in 23 municipalities and 5 autonomous counties in Xinjiang.The proportion of male to female accounted for 50％ each.Results The overall prevalence of valvular heart diseases was 7.67％ (male:7.31％ vs.female:8.00％).The prevalence rates of valvular heart diseases were 10.57％,2.36％ and 12.22％in Han,Uygur and Kazakh populations,respectively.The prevalence of valvular heart diseases was lower in Uygur than in Hazak and Han ethnic populations ( x2=3.90,P=0.000).Complications related to valvular heart diseases would include hypertension (63.20％),diabetes (7.60％),coronary heart disease (7.50％) and fibrillation atrial (3.20％).Conclusion The prevalence of valvular heart diseases had a substantial increase,parallel with age.Differences were seen on the prevelance rates of VHD among ethnic populations.

OBJECTIVETo investigate the association between the polymorphism of prostacyclin synthase gene (CYP8A1) and myocardial infarction (MI) in Uigur population.

METHODSTotally 210 patients with MI and 206 healthy control subjects were detected by polymerase chain reaction and restriction fragment length polymorphism. The serum 6-keto-PGF(1alpha) was detected with radioimmunoassay kit in all subjects.

RESULTSThe frequencies of CC, AC and AA were 0.024 (5/210), 0.124 (26/210) and 0.852 (179/210) in MI group while ones those 0.010 (2/206), 0.073 (15/206) and 0.917 (189/206) in the controls. There was no significant difference in frequencies of CC, AC and AA genotypes between controls and MI cases (chi(2) = 0.782, P > 0.05), but the frequency of CC + AC genotype in MI group [0.14 (31/210)] was higher than that in the controls [0.083 (17/206)] giving significant difference (chi(2) = 4.321, P = 0.031). The C allele frequency in the MI group [0.086 (36/420)] was higher than that in the controls [0.046 (19/412)] showing significant statistical difference (chi(2) = 5.284, P = 0.021). There was significant difference (t = 6.255, P < 0.01) in serum 6-keto-PGF(1alpha) level between MI group [(17.40 +/- 4.56) pg/ml] and control group [(20.34 +/- 5.02) pg/ml]. In the cases and control group, the serum 6-keto-PGF(1alpha) level of the persons with CC + AC genotype [(14.30 +/- 3.31) pg/ml, (18.31 +/- 4.62) pg/ml] was lower than those of AA genotypes [(19.34 +/- 5.51) pg/ml, (25.10 +/- 5.00) pg/ml], and the statistical significance was also observed (t' = 6.934, P < 0.05; t = 5.393, P < 0.01). Logistic regression analysis showed that the C allele of the CYP8A1 gene was an independent risk factor for MI (OR = 1.77; 95% CI: 1.06 - 2.05).

CONCLUSIONThe C allele of CYP8A1 might be a risk factor of MI in Uigur population, and be resulting from the decrease of serum 6-keto-PGF(1alpha) level for gene variation.
