Objective To investigate the echocardiographic features in patients with right atrial myxoma and thus evaluate the value of echocardiog?raphy in the diagnosis of right atrial myxoma. Methods The echocardiographic findings of 20 patients with right atrial myxomas were retrospectively analyzed,and the echocardiographic features of these patients were summarized. Results The main clinical symptoms of right atrial myxoma includ?ed chest tightness,shortness of breath,lower limb edema,and syncope. Of these 20 patients,the echocardiography showed that the average size of the right atrial myxomas was 3.11 cm × 2.90 cm to 7.44 cm × 4.52 cm. The myxomas were round or oval shape in 15 patients(75%)and lobulated shape in 5(25%). The myxomas were attached to the atrial septum in 15 patients(75%)and to right atrial free wall in 25%of the patients. The aver?age width of the basement was 1.62±0.30 cm,and the width was greater than 1 cm in 80%of the patients had the width over 1 cm. Some myxomas had internal areas of calcification and anechoic cystic areas. The percentages of patients with the blocking of right atrium,tricuspid and pulmonary hy?pertension were 70%,50%,and 10%,respectively. Conclusion The echocardiographic features of right atrial myxoma were specific. Echocardiog?raphy can accurately assess the tumor and identify the secondary changes in cardiac structure and hemodynamics and thus provide evidence for time?ly and accurate diagnosis of right atrial myxoma.

Objective To discuss the clinical value of the suture of sacral ligament and pubovaginalis fascia plus sacrospinous ligament fixation in the treatment of moderate and severe pelvic organ prolapse ( POP) . Methods Thirty-two cases with moderate or severe POP,who were treated by the suture of sacral ligament and pubovaginalis fascia besides sacrospinous ligament fixation,were retrospectively analyzed. Results The locations of POP in the 32 patients were mainly in the anterior and middle pelvis cavity. The degree of uterine prolapse was not less than POP-Q Ⅲ phase. The anterior and/or posterior vaginal walls were also prolapsed. The patients were treated by the transvaginal panhysterectomy,vaginal wall neoplasty,sacrospinous ligament fixation and the suture of sacral ligament and pubovaginalis fascia. Those with stress incontinence were also treated with urethral posterior ligament plication. The operation time was 60~120 min,and the hemorrhage vol-ume was 100~300 mL. There were no severe complications or recurrence in all patients. Conclusion The suture of sacral ligament and pubovaginalis fascia could greatly reduce the hazard rate of the recurrence of anterior pelvic organ defects in POP patients treated by sacrospi-nous ligament fixation. The suture operation could strengthen the anterior pelvis cavity,and was proven to be simple,secure and effective. Therefore,the operation is valuable to be used in clinical application.

Objective To study whether Clonorchis sinensis eggs were involved in the pathogen esis of gallbladder stones.Method From March to August 2011,the gallbladder stones from 183 patients were studied using microscopic examination and FTIR spectroscopy.Twenty egg-positive and 20egg-negative gallbladder stones found under microscopic examination were chosen randomly and analyzed through real-time fluorescent PCR and scanning electron microscopy.Results Eggs were detected in 118 of 183 gallbladder stones.The eggs were preliminarily diagnosed as Clonorchis sinensis eggs using the morphologic characteristics under light microscope.The results of real-time fluorescent PCR showed eggs in the gallbladder stones were Clonorchis sinensis eggs.The 118 egg-positive gallbladder stones were composed of 97 pigment stones,21 mixed stones and no cholesterol stones.The detection rate of Clonorchis sinensis eggs in pigment stones were the highest among the three types of gallbladder stones (P＜0.001).The 20 egg-positive stones were observed by scanning electronic microscopy:dozens or even hundreds of Clonorchis sinensis eggs were visible under 400 times magnification; and a dozen or even dozens of Clonorchis sinensis eggs and the surrounding particles were adherent to or parceled with each other under 1000 times magnification.While under 3000 times magnification,uneven texture was seen on the surface of eggs with pieces being shed from some eggs.Some eggs were hollow or without cover.Most of them were adherent to or wrapped with amorphous particles or mucoid matter.Conclusions A large amount of Clonorchis sinensis eggs were detected in gallbladder stones.Clonorchis sinensis eggs were associated with the formation of gallbladder stones,especially with pig ment stones.

Objective To construct a naive human Fab fragment phage display library,from which the anti-gp96 antibodies may be panned by the gp96 purified from the tissue of urothelial carcinoma in the urinary bladder and provide a basis to new therapy for the malignant tumors.Methods Peripheral blood lymphocytes were isolated from 800 ml of blood,which was obtained from four healthy blood donors.The heavy chain Fd and light chain cDNA synthesized from the total RNA of lympbocytes were amplified by PCR with variable regions 5' and 3' primers of heavy and light chain, and the amplification products were ligated into the phagemid vector pComb3, then the ligated sample was transformed into competent E.coli XL1-Blue by electroperation.The transformed cells were infected with VCSM13 helper phage to yield recombinant phage antibody Fabs.The phagemids abstracted from amplified E.coli were cut with endonucleases such as Sac Ⅰ,Xba Ⅰ,Xho Ⅰ and Spe Ⅰ, and both the phage antibody Fabs and phage-raids abstracted from amplified E.coil were amplified by PCR to monitor the insertion of the genes of light chain or heavy chain Fd fragment.The gp96 purified from the urothelial carcinoma tissue of the bladder by affinity chromatog-raphy on eoncanavalin-A sephnrose and DEAE-sephnrose ion exchange chromatography were utilized as antigens to process three rounds of panning to the original Fab antibody library.Results The quantity of total RNA and cDNA were qualified.By combination of light chain and heavy chain genes, an antibody library containing 6.6×106 clones was obtained, and both the cutting of enzymes and PCR showed that there were the genes of light chain or heavy chain Fd fragment in the phagemids.The gp96 protein was obtained from urothelial carcinoma tissue in the urinary bladder.After having been panned by gp96, the original antibody library gained enrichment by 68 times.Conclusion Utilizing the technology of phage surface display, specific antibody can be gained from the human naive Fab phage display library,which can be used for immunological therapy for tumors.

Objective To investigate the expression of β-catenin and Oct-4 in colonal carcinoma and explore the relationship with recurrence and metastasis after operation. MethodsImmunohistochemical analysis was used to evaluate the expression of β-catenin and Oct-4.The correlation of β-catenin and Oct-4 expression with tumor cell differentiation,T stage,N stage and metastasis was analyzed.The gene expression of Oct-4 was examined by RT-PCR in 20 frozen tumor tissues and normal tissues adjacent to tumor.Results Thirty-five patients had metastasis. The positive rates of β-catenin and Oct-4 expression were significantly higher in metastasis group than in the non-metastasis group (65.71％ vs 31.11％,51.43 ％vs 13.33 ％,x2 =9.843,P =0.002,x2 =13.605,P =0.001).Expression of β-catenin and Oct-4 was not associated with differentiation,T stage or N stage.The positive expression rate of Oct-4 in colonal carcinoma tissues was significantly higher than that in normal tissues.Metastatic rates in patients with positive expression of β-catenin and Oct-4 was higher than that in negative expression.The survival analysis showed that time of metastasis was significantly different in two groups of patients (P ＜0.05).Conclusion The expression of β-catenin and Oct-4 in tumor tissues is related to metastasis of colonal cancer after surgery and might be used to predict metastasis of colonal cancer after operation.
