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 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.

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 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 explore the prevalence of syphilis and HSV-2 among female sex workers (FSWs) who use new types of drugs in Jiaozhou city.
METHODSThrough convenient sampling, an anonymous questionnaire survey was conducted among female sex workers to collect demographic characteristics, new-type drugs abusing characteristics and related sexual behaviors from October to December, 2013. Blood specimens were drawn for serological tests of syphilis antibody and HSV-2 antibody. Urine specimens of the subjects surveyed were collected to test for methamphetamine. Differences in demographic characteristics, new-type drug abusing characteristics, and sexual behaviours between drug-abusing FSWs and non-drug-abusing FSWs were compared by t-test and χ(2)-test.
RESULTSA total of 460 FSWs were recruited in this study, and 105 FSWs admitted their drug abuse history. Among the 341 urine specimens confirmed to be methamphetamine positive, there were 3 FSWs claimed that they never abuse new-type drugs. The rate of new-type drug abuse was 23.5% (108/460). A total of 71.4% (75/105) of the new drug-abusing FSWs started using drugs under 25 years old. The main reasons for drug abuse were clients request (24, 22.9%), making more money (23, 21.9%) and companion temptations (22, 21.0%). Totally, 41.9% of them (44/105) took drugs with 4-5 persons, 32.4% (34/105) had sex with 2-3 men after taking drugs, and 60.2% of new-type drug-abusing FSWs (65/108) used condoms in the latest commercial intercourse, while only 7.4% FSWs (8/108) used condoms every time during their commercial sex activities in the recent month. Compared with FSWs having no drug abuse behavior, drug-abusing FSWs had higher single proportion (73.2% (79/108) vs 63.6% (224/352), χ(2) = 8.64, P < 0.05), lower condom use rate in the recent month (7.4% (8/108) vs 22.7% (80/352), χ(2) = 12.53, P < 0.01) and higher pregnancy rate in the recent 6 months (24.1% (26/108) vs 8.8% (31/352), χ(2) = 17.74, P < 0.01) and most of them come from the middle and high-level entertainmens (78.7% (85/108) vs 65.1% (229/352), χ(2) = 13.09, P < 0.01). Among the new-type drug-abusing FSWs, the prevalence rates of syphilis and HSV-2 were 12.0% (13/108) and 55.6% (60/108) , respectively. A total of 33 FSWs claimed that they were diagnosed with STDs in the recent year (30.6%) . The rates of syphilis(12.0% (13/108) vs 4.0% (14/352), χ(2) = 9.72, P < 0.01), HSV-2(55.6% (60/108) vs 39.2% (138/352), χ(2) = 9.01, P < 0.01) and diagnosed STDs (30.6% (33/108) vs 17.9% (63/352), χ(2) = 8.02, P < 0.01) among the drug-abusing FSWs were significantly higher than those of non-drug-abusing FSWs.
CONCLUSIONThere is a higher proportion of new-type drug abuse among the FSWs in Jiaozhou, with significantly higher prevalence rates of syphilis and HSV-2 infection, compared with non-new types of drug abusing FSWs. Prevalent risk sexual behaviors and ignorance of new-types drugs' harm were seen among them.
