Objective: To explore and practice the method of quality management of software about medical apparatus and instruments so as to ensure the quality of software. Methods:The quality management system of software developed from medical X-ray imaging equipment was constructed through two aspects included target management (quality measurement of qualitative and quantitative were adopted to ensure the quality of software could achieve predictive target) and process management(included the development management of Scrum mode, change management of process and version control based on Git technique. Results: After this method of quality management of software about medical apparatus and instruments was implemented, the software quality and satisfaction of customer were obviously enhanced. Conclusion: Through the control and management of two aspects, the target for ensuring and enhancing quality of software was achieved.

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.

ObjectiveTo determine the clinical effect and the prospect of cervical side-to-side stapled esophagogastric anastomosis. MethodsEighteen cases of upper and middle thoracic esophageal carcinoma were treated with esophagectomy and cervical side-to-side stapled esophagogastric anastomosis. The clinical data were collected and retrospectively analyzed. The average age of patients was 60.7 years and the ratio of male to female was 17∶1. The tumor included 4 upper part and 14 middle thoracic parts. The length of tumors was from 1 cm to 7 cm, with an average of 3.2 cm.ResultsThe post-operative TNM staging(AJCC) included 4 Stage Ⅱa,9 Stage Ⅱb,and 5 Stage Ⅲ. The operative incisions included 8 nontransthoracic cervical and abdominal double incisions, 9 right cervico-thoraco-abdominal triple incisions, and 1 left cervico-thoracic incision. One (5.56%) patient complicated with anastomotic leakage and was cured in 2 weeks by cervical drainage and absolute diet. All the 18 patients were followed up for 1 to 5 years,and no anastomotic stricture was found. Reflux esophagitis was found in 2 and the incidence rate was 11.11%.ConclusionCervical side-to-side esophagogastric anastomosis is a safe procedure with larger resection of margins and fewer complications. It is worth replicating.

Objective To approach the advantages and summarize the experience of mesh & plug tension-free hernia repair. MethodsThe mesh & plug tension-free hernia repair was administered in 102 patients of groin hernia with the BardR Mesh & PerfixR plug offered by Bard Company in U. S. A. The operation time,postoperative pain,patient's ability recovery, complications and recurrence rate were followed up. ResultsThe average operation time was 31.5minutes. The patients could move 4～6 hours after operation. Postoperative pain lasted about 2～3 days. One had retention of urine and two had wound subcutaneous hydrops. No wound infection. Nine had feeling of foreign matter in the groin region. Only one had recurrence in 89 patients who were followed-up. ConclusionBardR Mesh & PerfixR Plug has good tissue-compatibility,no rejection,and capability of anti-infection. It is an ideal material for hernia repair. The mesh & plug tension-free hernia repair is easy to be administered, with minor lesion, quicker recovery and lower recurrence. And the operation indication can be widened. It is a most advanced method in treating groin hernia.

Objective:To construct eukaryotic expression vector for anti-human melanoma chimeric antibody,and express the antibody in eukaryotic cells.Methods:Variable regions of the murine antibody were cloned from the anti-human melanoma hybridoma cell line HB8459,HB8760,Mel3,and was inserted them into the chimeric antibody eukaryotic expression vector pMH-CA.The constructed vector was transfected into 293T,the chimeric antibody was expressed,as detected by RT-PCR,ELISA,and Western blot.Results:Eukaryotic expression vectors of the chimeric antibody against human melanoma were successfully constructed,and expressed in eukaryotic cells.The expression of chimeric gene was confirmed by RT-PCR,specificity of the chimeric antibody was proved by ELISA and Western blot.Conclusion:Anti-human melanoma chimeric antibody was expressed successfully.

Objective To explore the cognition processes of language in stroke patients by characterizing the differences between the event-related potentials (ERPs) N400 evoked bypicture-word andsentence-wordparadigms.Methods Twenty patients with a single brain lesion resulting from a first episode of stroke were tested along with 20 normal controls.Their N400 ERPs were tested using pictures and sentences as activating stimuli and phrases composed of nouns and verbs as the target stimuli.The N400 potentials were recorded from electrodes located at Fz,Pz,T3 and T4 positions of the International 10-20 system.The N400 latencies and amplitudes and the behavioral responses of the experimental and control groups were compared.Results The latencies were longer and the amplitudes were lower in response to sentence activation than to picture activation.The differences in terms of amplitude were the greatest with N400 recorded from Pz.The responses to the target stimuli were not significantly different with regard to the types of stimuli and recording location.The average response time was longer and the error rate was higher in response to sentence activation than to picture activation.Conclusion Multiple accesses,activating stimuli and integrating processes are involved in language cognition.The brain is more sensitive and accurate in response to picture stimuli in language cognition.The response to sentence stimuli is slower,and the error rate is higher.This suggests that it is better to usc varied prime stimuli in teaching children languages.

The application of PET-CT could not only play a part in the diagnosis of clinical stage for NSCLC on PET, but also make full use of the discrimination of anatomical structure on CT. The precision of target contouring could be increased and the normal tissue and risk organ are also protected efficiently.

The involvement of oxidization of peroxid in the antigen-antibody reaction makes the cell membrane permeability enhanced, so the fluorescence-labeled antibody stain can infiltrate into the cell easily and contact the antigen rapidly and diffusely, and then the antigen-antibody crosslinking can be formed efficiently. With the enhanced staining efficiency, shortened test duration, simplified operation, increased positive detection rate and accuracy, the new technology lays a foundation of clinical definite, curative effect view and prognosis.
