To investigate an approach of treatment for atrial fibrillation with discrete ablation lesion, 12 dogs with experimental atrial fibrillation underwent radiofrequency catheter ablation. Atrial lesion was made at the most vulnerable site. The results showed that in 10 of 12 dogs persistent fibrillation could be ablated. There was no significant change in sinus heart rate, P wave duration, and corrected sinoatrial node recovery time (cSNRT). The results suggested that paroxysmal atrial fibrillation could be eliminated by point ablation of the lesion, and that trigger activity might be involved in the mechanism of atrial fibrillation.

Objective To explore the diagnosis and operative treatment of spinal tumor. Methods Clinical symptom, diagnosis and operative treatment of 22 patients with spinal tumor in our institution from August 1987 to August 2002 were analysed retrospectively. Results Combining with patients' clinical symptoms and results of corresponding examination, all cases were diagnosed before operation. After operation, all the patients recovered with different outcome except 3 patients died. There were 18 cases nearly cured. Conclusion The clinical symptoms of the patients with spinal tumor have some specialty. The preoperative diagnosis mainly depends on MRI. The various operative modes should be taken according to tumor localization.

ObjectiveTo explore the clinical characteristics and diagnosis of primary small intestinal tumor (PSIT). MethodsRetrospective analysis of the clinical and pathological data of the 112 PSIT cases was made. ResultsDuodenum was the most common site for PSIT (62 5%). Leiomyomas were most common benign tumors which were most likely found in ileum and jejunum. Adenocarcinoma was the most frequently seen malignant PSIT followed by lymphoma and leiomyosacroma. The chief method of diagnosis is barium meal X ray examination especially with the hypotonic contrast X ray examination. Endoscopy can increase the diagnostic rate. Superior mesenteric arteriography sometimes helps in determing the site of gastrointestinal haemorrhage. CT scan can be helpful in establishing diagnosis, preoperative classification and postoperative recurrences. Conclusion Duodenal adenocarcinoma is most common PSIT, followed by malignant lymphoma, liomyoma and leiomyosarcoma. Hypotonic contrast X ray examination is most effective in diagnosis, and locating of small bowel tumors. Superior mesenteric artery angiography and CT scanning are also helpful.

Objective To explore the effects of different methods of antigen retrieval on the results of immunohistochemical staining of nuclear receptors. Methods Antigens were retrieved by using microwave oven, autoclave, enzyme and autoclave plus enzyme, respectively, in liver sections from DA.1U rats, followed by immunohistochemical staining. Results After antigen retrieval with autoclave, the positive staining intensity of nuclear receptors LXR-α, LXR-β, PPAR-γ and FXR in the liver sections from DA.1U rats was enhanced obviously, and the location of nuclear receptors was better by using this method than the others. Conclusion In the immunohistochemical staining of nuclear receptors, using autoclave to retrieve antigens is the best method.

Objective To explor the ultrasonography methodology of the fetal ductus arteriosus.Methods Based on the fetal four-chamber sight, the characteristic ultrasound images were observed by moving probe,such as "V-shape" sign,"three-finger" sign,"Z-shape" sign and"hockey-handle" sign making up of the ductus arteriosus and the nearby structures were observed by moving probe. The inner diameter,the systole flow velocity,the diastole flow velocity and the resistance index of the ductus arteriosus via the "V-shape" sign section were measured. Results Among the 365 normal fetus cases,355 "V-shape" sign cases,237 "three-finger" sign cases,298 "Z-shape" sign cases and 331 "hockey-handle" sign cases were identified. The inner diameter of the fetal ductus arteriosus increases gradually with the growth of the gestational weeks and the flow velocity increases gradually too, while the resistance index had no obvious variation with the growth of the gestational weeks. Conclusions According to the characteristic ultrasound images, such as "V-shape" sign, "three-finger" sign, "Z-shape" sign and "hockey-handle" sign, the fetal ductus arteriosus can be identified promptly.

ObjectiveTo study the value of the exfoliative cytology of prostatic fluid obtained from patients with elevated PSA in prostate cancer diagnosis.MethodsProstatic fluid was obtained from 130 patients with elevated PSA before prostate biopsy and then the Wright's stain and cytological class were done.Each cytological class and patient's age,PSA,total prostate volume,prostatic fluid volume and the number of leukocyte in the prostatic fluid were recorded.The relationship of leukocyte number and patient's age,PSA and prostate volume was analyzed by Spearman correlation test.ResultsProstate biopsy pathology results showed that there were 77 (59.2%) cancer cases and 53 (40.8%) non-cancer cases.Patient numbers in cytological class 1 to 5 were 28 (21.5%),32 (24.6%),22 (16.9%),36 (27.7%),12(9.2%),respectively.The prostate fluid cytology had a specificity of 100% and high sensitivity of 62.5%(10/16) in patients with PSA≥20 μg/L.PSA value had significant difference between class 1,2,3,4and 5.Significant correlation was found among the prostatic fluid volume,total leukocyte number and prostate volume.Prostate volume,leukycyte density and total leukycyte number was significant higher in noncancer patients than in prostate cancer patients.ConclusionsThe exfoliative cytology of prostatic fluid is a valuable method in detecting prostate cancer,particularly in patients with high PSA levels.It has the advantages of non-invasion and less injury than prostate biopsy.There is a relationship between elevated PSA value and high leukocyte numbers.
10.Short- and long-term respiratory complications in late preterm infants: a review
Chinese Journal of Perinatal Medicine 2018;21(12):850-854
There are more and more late preterm infants in recent years. Due to the immature physiological and metabolic functions, late preterm neonates are more prone to various short- and long-term respiratory complications in their early postnatal period, such as neonatal respiratory distress syndrome, wet lung and apnea in the short term, and asthma and respiratory syncytial virus infection in the long term, which significantly increase the admission and fatality rate of late preterm infants in their infancy and school age compared with the full-term ones. Clinicians should be much aware of the short- and long-term respiratory complications in late preterm infants so as to promote clinical management and improve the long-term quality of lives of these infants.
