Objective:Through to the CR in imaging, scanning and transmission process of artifact analysis, find out the causes of artifacts, and to explore methods and countermeasures to reduce and eliminate artifacts, improve the quality of CR picture. Methods:Collected between September 2009 and mid-February 2012 CR images of 103 cases with artifacts, through the analysis of the morphology and characteristics of image artifacts on the causes of artifacts. Results:from 103 have artifacts in the image analysis and proof, the photography, scanning and so on ordinary maintenance produces CR image artifacts, most of the artifacts, through the corresponding processing, most of them can reduce and eliminate. Conclusion:As long as technicians and maintenance engineers to strengthen the sense of responsibility, familiar with the working principle of CR equipment and strengthen the ordinary maintenance, CR image artifacts can be avoided and eliminated.

Objective:To observe the surgical effects of laparoscopy and choledochoscope combination in the treatment of common bile duct stones and the complications occurrence situation,so as to provide reference for the clinical surgical treatment for common bile duct stones.Methods:The clinical materials of 120 common bile duct stones received surgical treatment in the Hepatobiliary Surgery of our hospital from January 2013 to January 2015 were retrospectively analyzed,and were divided into two groups according to the surgical approaches.The control group were given conventional open cholecystectomy,and the research group were given laparoscopy and choledochoscope combination surgery.The surgical situations and complications in these two groups were observed.Results:The surgical time in the research group was significantly longer than in the control group (P＜0.05),the blood loss,gastrointestinal recovery time,ambulation time,hospital stay were significantly shorter than in the control group (P＜0.05);the complication incidence such as pain,infection,bile leakage,residual stone in the research group was 8.3％,significantly lower than 21.7％ in the control group (P＜0.05).Conclusion:The combination treatment of laparoscopy and choledochoscope in the common bile duct stones has good curative effects,less blood loss,rapid recovery,and less impact on the gastrointestinal function,low incidence of complications,and can significantly shorten the length of hospital stay,can be used as the first choice in clinical practice.

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 explore the clinical analysis of 65 cases of elderly patients with gastric carcinoma. Methods The clinical data of 65 cases of elderly patients with gastric carcinoma from October 2002 to September 2007 were analyzed retrospectively. Results 34 eases took place a variety of complications in this group of 26 cases of patients,and they are 5 cases of incision dehiscence,2 cases of anastomotie leakage, 1 cases of duodenal stump leakage,1 cases of gastric dysfunction,ll cases of heart failure,14 cases of lung infection,3 cases of urinary tractin-fection, two case of intra-abdominal infection, two cases of intestinal obstruction, 1 case of postoperative died. Conclu-sion As early as mid-term elderly gastric cancer should be perfrmed radical resection,at the same time,prevent and treat complications actively.

Risk factors related to malnutrition were prospectively studied in 82 cases with acute ischemic stroke in our hospital during December 1,2007 and December 31,2008. The incidences of malnutrition on the first and ( 14 ± 1 )th day were 18% (15/82) and 30% (25/82). Study showed that age ( P = 0. 007 ), dysphagia ( P = 0. 043 ), malnutrition on admission ( P = 0. 003 ) were risk factors related to malnutrition on the ( 14 ± 1)th day after admission; there was no interaction between dysphagia and the other two factors, dysphagia was an independent risk factor related to malnutrition after acute ischemic stroke.

Malnutrition is significantly correlated with the high mortality and other poor outcomes of stroke;in turn,stroke can increase the incidence of malnutrition.Old age and swallowing dysfunction are independent risk factors of post-stroke malnutrition.The sequential nutritional support with enteral nutrition and parenteral nutrition can reduce or avoid the complications of both malnutrition and stroke,and therefore should be considered for stroke patients,especially those who are critically ill.

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 observe the clinical effect of treating acute mastitis with tuina manipulation.Method: Tuina manipulation was applied to treat 32 cases in the observation group, while external Jinhuang san was applied to treat 16 cases in the control group. Result: The total effective rate in the observation group was 96.8% and the total effective rate in the control group was 87.4%. The therapeutic effect of the two groups had significant difference (P＜0.01) and the treatment period and times between the two groups had significant difference as well (P＜0.01). Conclusion: Tuina manipulation had better effect for acute mastitis.

ObjectiveTo investigate the postoperative analgesic activity offlurbiprofen to intracranial aneurysm patients who went under endovascular treatment with propofol and remifentanil anesthesia.Methods Totally 40 ASA physical status Ⅰ - Ⅱ intracranial aneurysm patients were randomly scheduled flurbiprofen group (group F, 20 cases) and control group (group C, 20 cases). The patients in group F were given flurbiprofen 1 mg/kg respectively at 10 min before operation and at the end of the operation; while the patients in group C were given fat milk at the same time. The patients' circulation of the two groups before and after operation,the headache visual analog scores (VAS) and body comfort score (BCS) were observed.ResultsThe mean arterial pressure(MAP) in group C after operation 1,2 and 3 h were significantly higher than that before operation (P ＜ 0.05 ); the heart rate in group C after operation had no significantly difference compared with before operation (P ＞0.05). The MAP and the beart rate in group F had no significantly differences before and after operation(P ＞ 0.05 ). The VAS of postoperation headache after operation 1,2 and 3 h were (0.30 ± 0.65 ), (0.30 ± 0.57) and (0.25 ± 0.44) scores in group F, which were significantly lower than those in group C [ (3.25 ± 1.58), (3.00 ± 1.56) and (2.90 ± 1.48 ) scores](P ＜ 0.05 ) ; the BCS after operation in group F after operation 1,2 and 3 h were (3.30 ±0.86), (3.45 ±0.86) and(3.62 ±0.86)scores, which were significantly higher than those in group C [ ( 1.20 ± 1.00), ( 1.45 ± 0.94) and ( 1.50 ±1.00)scores](P＜ 0.05 ). ConclusionFlurbiprofen can reduce intracranial aneurysm patient's postoperative headache under endovascular treatment.
