ObjectiveTo study the diagnosis of thyroid cancer concurrent with multiple thyroid nodules.Methods The clinical data of 23 patients of multiple thyroid nodules with thyroid cancer undergoing exploration from May 1988 to December 2000 were analyzed retrospectively.ResultsThe diagnosis of concurrent carcinoma was made preoperatively in 6 cases. 13 out of the 23 patients underwent second operation for the postoperative pathology being malignant. Thyroid cancer was identified concurrent with benign nodules in 20 cases. Conclusion Thyroid cancer when found on the background of multiple thyroid nodules is often coexistant with benign thyroid disease, hence the diagnosis is difficult to make clinically. Second operation is sometimes inevitable when the pathology identified a cancer in preoperatively diagnosed benign nodules.

Objective To analyze the effect of perioperative blood transfusion in orthopedic surgery.Methods A total of 201 patients who underwent an orthopedic surgery in our hospital in October 2015 to September 2016 were reviewed.Hemoglobin concentrations,hematocrit,postoperative hospital stay,infection and other related data were analyzed.Results 90 patients were transfused with blood and in 111 patients were not during orthopedic surgery (massive blood transfusion group including 17 cases;non massive blood transfusion group including 94 cases).Hemoglobin concentrations of transfusion group (103.09±16.37)g/L was lower than the non transfusion group (115.79± 13.68)g/L before liying hospital,postoperative hospitalization time of transfusion group (12.012±8.36) was longer than that of non transfusion group (16.14 ± 10.47)days.Postoperative infection rate in non transfusion group was 1.11％,and in transfusion group was 15.32％,in massive transfusion group is 52.94％.Conclusion Perioperative blood transfusion is not conducive to the recovery of hemoglobin level patients in orthopedic surgery,prolong hospital stay and increase the rate of infection after surgery.Perioperative blood transfusion makes it difficult to support the outcome of the disease

Objective To investigate the prevalence of H.Pylori infection and antibiotic resistance in patients with peptic ulcer.Methods A retrospective analysis of 429 endoscopy and H.Pylori culture results in the First People's Hospital of Hangzhou from 2012 to 2013 was conducted.The rate of H.Pylori infection in patients with peptic ulcer, and the resistance rates of H.Pylori to metronidazole, levofloxacin, clarithromycin,amoxicillin, gentamicin, furazolidone were analysed.Results The positive rate of H.Pylori in people with peptic ulcer was 53.1％ (228/429).The resistance rates to metronidazole, levofloxacin, clarithromycin,amoxicillin, gentamicin and furazolidone were 94.7％ (216/228), 18.9％ (43/228), 18.9％ (43/228), 0, 0 and 0.Double antibacterial resistant rates of metronidazole and clarithromycin, metronidazole and levofloxacin were 18.0％ (41/228) and 17.1％ (39/228).Triple antibacterial resistant percentage of levofloxacin + metronidazole + clarithromycin was 8.3％ (19/228).The resistance rate of clarithromycin in 43 patients who were also resistant to levofloxacin was 46.5％ (20/43), while the resistance rate of clarithromycin in 185 patients who were also sensitive to levofloxacin was 12.4％ (23/185)with significant difference(x2 =26.480,P =0.000).A positive association between the resistance to levofloxacin and to clarithromycin was found.Conclusion The H.Pylori infection is closely related to the occurrence of peptic ulcer.Without the basis of culture results in patients with H.Pylori positive, amoxicillin, gentamicin and furazolidone could be the first choices in clinical,because of their low resistance rates.Clarithromycin can be used as an alternative.

Objective Wether preoperative freezing plus traditional operative resection would improve 5 year survival of patient with esophageal cancer was studied. Methods 50 patients admitted for esophageal cancer were divided equally at random.The treatment group (n=25) received cryotherapy before traditional surgery.The rest,without pretreatment,had surgery as controls.Their 1,3,5 year survival rates were contrasted. Results With pretreatment the 1,3,5 year survival rate reached 92,76,56 percent respectively,while that of the controls attained 80,40,and 28 percent accordingly.Statistically significant difference in survival did exist between groups by the end of 3 and 5 years after the combined therapy, yet no difference was detected within 1 year. Conclusion Preoperative cryotherapy could reduce the possibility of lymphatic metastasis,iatrogenic spread during operation and improve patient’ s immunological functions and life span.

Objective To investigate the association of the gene polymorphism of plasminogen activator inhibitor 1 (PAI 1) with the cerebral infarction and recurrent cerebral infarction (RCI). Methods The plasma PAI 1 activity, by means of chromgenic substrate assay, and the sequence polymorphisms of 4G/5G in promotor region and (CA)n dinucleotide repeats in the 4th intron of PAI 1 gene, by amplified fragment length polymorphism assay, were measured in 50 patients with first ever cerebral infarction (FCI), 45 patients with RCI and 60 healthy controls.Results The plasma PAI 1 activities in both FCI patients (1.13?1 1 AU/ml) and RCI (1.13?0.150 AU/ml) were remarkably higher than that in the controls (0.7?0.25 AU/ml) (both P

BACKGROUND:Many previous experiments have confirmed that transforming growth factor?1(TGF-?1) plasmids can inhibit or decrease the injection in nerve transplantation,but there has rare report about their effects on vein transplantation.OBJECTIVE:To investigate the action pathway of immune tolerance of allogenic femoral vein transplantation in rats induced by local injection of TGF-?1.DESIGN,TIME AND SETTING:A randomized block animal observational experiment was performed at Animal Experimental Center of Harbin Medical University from March 2007 to April 2008.MATERIALS:A total of 18 Wistar rats were selected to assign as donors.A total of 48 Sprague Dawley rats were selected to assign as recipients and randomly divided into four groups with 12 rats in each group:autograft,allograft,immunosuppressant,and TGF-?1 groups.METHODS:The rats in the immunosuppressant group were administated(i.p.) cyclosporin A(10 mg/kg) one time per day from three days before transplantation till they were sacrificed.Each rat in the TGF-?1 group was injected 40 ?g TGF-?1 plasmids into two ends of femoral vein.Vein transplantation was performed in the autograft and allograft groups.MAIN OUTCOME MEASURES:Imaging,histology and immunological assays of these groups were conducted at two weeks after transplantation.RESULTS:In the autograft group,the endothelial cells of vein were flat,and nuclear membrane thickened.In the allograft group,the exfoliated endothelial cells and fragments,as well as subendothelium were observed.In the immunosuppressant group,the nuclear membrane of endothelial cells thickened,and rough endoplasmic reticulum expanded widely.In the TGF-?1 group,the expand of rough endoplasmic reticulum and mitochondrial vacuolation were observed.Tight junction could be seen between adjacent cells.Histologic and immunologic parameters in the TGF-?1 group were better than those in the immunosuppressant and allograft groups.The absorbance value of lymphocyte culture in the autograft,allograft,immunosuppressant,and TGF-?1 groups were 1.07?0.14,4.15?0.67,1.77?0.23 and 1.38?0.23,respectively.The absorbance value of lymphocyte culture in the TGF-?1 group was significantly lower than that in the immunosuppressant and allograft groups(P
