Objective:To investigate the epidemic features of allergic rhinitis(AR)and correlative risk factors in Shihezi city,Xinjiang province,China. Method:A question-naire survey on AR and airway diseases was conducted among 2300 elementry school children in 12 schools,aged from 9 to 10 years old,from july 10 to 25,2008. in Shihezi city,Xinjiang province.Suspects of AR was identified by the survey,then they were recommended to specialist examinations for accurate diagnosis. Allergen skin tests were peformed to explore the allergenic varieties of allergic rhinitis. Diagnosis criteria of AR were that of ARIA(Allergic rhinitis and its impact on asthma). Resuit:Two thousand two hundred and eleven questionnaires were returned. The response rate was 96.1% and 2205 questionnaires were available.The prevalence rate of AR in children aged from 9 to 10 was 12.56%(277/2205) in Shihezi city.The difference of prevalence between female 13.76%(153/1112) and male 11.34%(124/1093) was insignificant statistically(χ~2=2.924,P＞0.05). The positive rate of the allergen skin test was 65.3%. The most common allergen of allergic rhinitis were plants of the mugwort and house dust mite. According to the ciassification criteria of ARIA in 2001,of 155 children suffered from intermittent AR,112 cases were mild and 43 cases were moderate-severe,while 122 suffered from persistent AR,110 cases were mild and 12 cases were moderatesevere. 5.4%(15/277) patients with AR also had bronchial asthma.25.3%(70/277) of the children with AR had inherent predisposition.Conclusion:The prevalence rate of AR in children aged from 9 to 10 in Shihezi city is 12.56%. Strategy of prevention and treatment of AR can be worked out according to the epidemical feature of AR.

Objective To analyze experimentally the compressive strength of veneers on mottled teeth after Dul8e Nd:YAG laser irradiation.Methods Sixty motded teeth were extracted,including thirty maxdlary central incisors and thirty maxillary lateral incisors and each were divided equally into two groups randomly(experimental groups and control groups).The former were irradiated by pulse Nd:YAG lafer and then etched by 37%phosphorus acid.The latter only etched by 37%phosphorus acid.All the teeth were restored by composite resin veneers and tested with Instron 4505 electronic testing machine.The average collapse loads of the veneers of incisors were tested. The maximal compressive loads of the samples were obtained,then the experimental results were analyzed.Results The average collapse loads of central incisors of test groups and control groups were(0.342±0.053),(0.289±0.041) kN respectively,with a signiticant difference(t=3.16,P<0.05).The average collapse loads of lateral incisors of test groups and control groups were(0.321±0.041),(0.208 ±0.032)kN respectively.There was a significant difference when they were compared(t=7.66,P<0.05).Conclusions The compressive strength of the veneers incneases significandv when the mottled teeth are irradiated by pulse Nd:YAG laser.This method is worthy of recommending.

Objective To inquire clinical effects of hysteroscopic electroresection in the treatment of submucous hysteromyoma. Methods A retrospective analysis regarding curative effects of hysteroscopic electroresection in 72 cases of submucous hysteromyoma was carried out. Results The resected myoma was 1.5~7 cm in diameter, and the number of resected myoma was 1~3. The operation time was 10~90 min (mean, 30 min). The operation was accomplished on one session in all the 72 cases. No uterine perforation, bleeding and bowel injuries took place. Postoperative follow-up for 4~20 months in the 72 cases reported a satisfaction rate of 97 2% (70/72). Out of 6 patients who had pregnancy desire, 2 were pregnant with child and 1 of them had a delivery. Conclusions Hysteroscopic electroresection in the treatment of submucous hysteromyoma is safe and effective. It can markedly improve the menstruation and elevate the pregnancy rate.

Objective To explore the predictive value of P wave dispersion (Pd) and maximum P wave duration (Pmax) of 12 lead ECG in patients with atrial arrhythmia.Methods51 cases of atrial arrhythmia group from October 2013 to April 2015 in Jiashan County First People's Hospital, patients with frequent atrial premature atrial tachycardia, were examined for the determination of P wave dispersion by 12 lead electrocardiograms (Pd) and maximum P wave duration (Pmax), and 53 healthy persons (control group) were compared.ResultsAtrial arrhythmia group Pd and Pmax were significantly higher than the control group, the rate is Pmax=100ms with Pd=40ms high prediction of atrial arrhythmia sensitivity, specificity and diagnostic, Pd=40ms=100ms combined with Pmax diagnosis, the sensitivity increased, but the specificity and diagnostic rate of decline.ConclusionPd is an effective index to predict atrial arrhythmias, and the combined detection of Pd and Pmax can improve the diagnostic sensitivity.

BACKGROUND:Clinical treatment of epicondyle fractures and intercondylar comminuted fractures is quite tricky due to instability and spread to the articular surface. Common complications contained bone delayed union, nonunion, broken nails and broken boards. Internal fixation for fractures is various, but reasonable choice for clinical fixation plays a decisive role for repair of fractures.
OBJECTIVE:To explore the repair effects of various fixation methods on femoral condyle fracture from different aspects such as fracture type, bone healing, functional recovery and biomechanics.
METHODS:First author searched PubMed database and China National Knowledge Infrastructure for articles about various fixation methods in repair of femoral condyle fracture published from January 2000 to April 2014. Key words were“femoral condyle fracture, internal fixation, biomechanics, load-displacement, axial stiffness, horizontal shear stiffness”. Total y 142 articles were retrieved, but 39 articles met the inclusion criteria.
RESULTS AND CONCLUSION:Femoral condyle fracture caused the damage to normal anatomic structure of knee join, changed normal anatomical axis and the mechanical axis of knee joint. Therefore, anatomic reduction and rigid internal fixation are necessary. During treatment, the advantages and disadvantages of various fixation methods should be known. It is necessary to ful y evaluate the type of intercondylar fractures of the femoral condyle and soft tissue injury. According to biological characteristics of the human body and mechanical property, internal fixation device should be reasonably used. Individual treatment programs should be provided. Thus, the occurrence of postoperative complications should be reduced utmostly, resulting in a satisfactory repair outcome.

Phytoene synthase is a rate-limiting enzyme in the pathway of carotenoid biosynthesis.To aim at establishing a transformation of Ginseng callus cells, elevating the nutritive value through encouraging the composition of corresponding carotenoid,taking Ginseng callus cells as acceptor,psy gene were transformed into cells via Agrobacterium-mediated. The factors affecting genetict ransformation were also investigated seperately from concentrations of A.tumefaciens, age of Ginseng callus cells, infection time and co-culture time. PCR,PCR-Southern and RT-PCR analysis from the transferred gene plants proved that psy gene has been transferred into Ginseng callus cells and can be expressed. The content of ?-carotene was increased by an average of 26 times.A base of improving and raising the contents of carotenoid in the Ginseng callus cell was established.
