Objective To compare the value of the coronary angiography by dual source CT (DSCT)and the transthoracic echo-cardiography (TTE)in the diagnosis of patent foramen ovale(PFO).Methods Recruiting total 476 cases,those who had both of the coronary angiography by DSCT and TTE within 24 hours,collecting the diagnosis cases number and related data for analysis.Results There were 101 out of 476 cases(21.2%)that were diagnosed PFO by coronary angiography DSCT.There were 68 out of 101 cases (67.3%)combined with left right shunt in atrium and there were 33 of 101 cases (32.7%)had no findings in diagnosis of left right shunt(LRS).There were also 5 out of 101 cases combined with atrial septal aneurysm.Meanwhile,there were 71 out of 476 cases (14.94%)that were diagnosed PFO by TTE.5 out of them were combined with atrial septal aneurysm.The diagnosis rate of PFO by TTE combined with CDFI was less than coronary angiography DSCT(P<0.05).The diameter of the opening in PFO measured by DSCT and TTE were (2.55 ±1.62)mm and (2.71±1.41)mm respectively,which was no statistically significant (P>0.05).Con-clusion Coronary angiography DSCT is better than TEE in diagnosis rate and anatomical structures displing in PFO.

Objective To investigate the effect of intra-articular carboxymethylated ehitosan(CM- CTS)injection on inducible nitric oxide synthase(iNOS)expression in cartilage at the early stage of os- teoarthfitis(OA).Methods Thirty-two white rabbits were underwent unilateral anterior cruciate ligament transection(ACLT)and were randomly divided into 4 groups 5 weeks after transection.Rabbits of group A re- ceived 0.3 ml of 2% high molecular weight CMCTS(H-CMCTS)once every two weeks.Rabbits in group B were treated using 2% low molecular weight(L-CMCTS)CMCTS at:the same intervals.Group C rabbits were injected intra-articularly with 0.3 ml of 1% sodium hyaluronate(Na-HA)once a week.Animals of group D were not injected.At sacrifice,11 weeks following surgery,the expression of iNOS in cartilages was analyzed by immunohistochemistry and reverse transcription-polymerase chain reaction(RT-PCR)methods.Results Both immunohistochemistry and RT-PCR showed that the level of iNOS expression of cartilage in CMCTS in- jection groups was lower than that in Na-HA injection group and the untreated group.There was no significant difference in iNOS expression between the two different molecular weight CMCTS injection groups. No signifi- cant difference of iNOS expression in cartilage was found between Na-HA injection group and the untreated group.Conclusion CMCTS suppresses iNOS expression in cartilage during the early stage of OA.Na-HA treatment has no effect on iNOS expression in cartilage.

OBJECTIVETo establish discriminant functions of diarrhea-predominant irritable bowel syndrome (IBS-D) by studying it from quantitative diagnosis angle, hoping to reduce interference of subjective factors in diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

METHODSA Chinese medical clinical epidemiological survey was carried out in 439 IBS-D patients using Clinical Information Collection Table of IBS. Initial syndromes were obtained by cluster analysis. They were analyzed using step-by-step discrimination by taking information of four Chinese medical diagnostic methods and serum brain-gut peptides (BGP) as variables.

RESULTSClustering results were Gan stagnation Pi deficiency syndrome (GSPDS), Pi-Wei weakness syndrome (PWWS), Gan stagnation qi stasis syndrome (GSQSS), Pi-Shen yang deficiency syndrome (PSYDS), Pi-Wei damp-heat syndrome (PWDHS), cold-damp disturbing Pi syndrome (CDDPS). Of them, GSPDS was mostly often seen with effective percentage of 34. 2%, while CDDPS was the least often seen with effective percentage of 5.5%. A total of 5 discriminant functions for GSPDS, PWWS, GSQSS, PSYDS, and PWDHS were obtained by step-by-step dis- crimination method. The retrospective misjudgment rate was 4.1% (16/390), while the cross-validation misjudgment rate was 15.4% (60/390).

CONCLUSIONThe establishment of discriminant functions is of value in objectively diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

Objective To investigate the value of the imaging findings of soft tissue abnormality in the differential diagnosis between osteomyelitis and malignant bone tumor.Methods The CT and MRI findings of soft tissue changes in 57 cases of osteomyelitis and 70 cases of malignant bone tumor were retrospectively defined,observed,recorded and statistically analyzed.Results In 57 cases of osteomyelitis, 54 cases were examined with CT,and soft tissue swelling was presented in 52 cases (degree Ⅰin 19 cases, degreeⅡin 16 cases,degree Ⅲin 17 cases).Abscess-like cysts in soft tissue occurred in 6 cases,masses in 5,air in 1,fat-fluid level in 1 and sinus tract in 1.Among 14 cases examined with MR imaging,soft tissue swelling was presented in all cases (degreeⅠin 2 cases,degree Ⅱin 6 cases and degree Ⅲin 6 cases). Abscess-like cysts appeared in 3 cases and showed high signal in diffusion weighted imaging, mass in Ⅰand fat-fluid level in 1.Among 54 cases examined with CT in 70 cases of malignant bone tumor, soft tissue swelling was presented in 44 cases (degreeⅠin 29 cases,degreeⅡin 12 cases,degreeⅢin 3 cases).Soft tissue masses appeared in 49 cases,bone shell and shell-like calcification in 16 cases and neoplastic bone and neoplastic calcified cartilage within soft tissue mass in 25 cases.Among 49 cases examined with MR imaging,soft tissue swelling was presented in 46 cases (degree Ⅰin 21 cases,degreeⅡin 17 cases and degree Ⅲin 8 cases),and soft tissue masses appeared in 43 cases.The degree of soft tissue swelling and the occurrence of abscess-like cyst,mass,bone shell or shell-liked calcification in the rim of mass,neoplastic bone or neoplastic calcified cartilage in masses showed significant difference(P

Objective To explore the effect of intervertebral foramen puncture under image equipment guidance. Methods 52 patients with lumbar disc herniation from January 2014 to January 2017 were enrolled in this study. All the patients underwent lumbar posterior lateral approach for endoscopic surgery. Patients were divided into control group and observation group by random number table method, 26 patients in each group. The patients in the observation group were treated with ultrasound volume, and the patients in the control group were treated with C arm X-ray machine. The intraoperative condition, preoperative and postoperative visual analogue scale (VAS score), Oswestry dysfunction index (ODI score) and postoperative complications were compared between the two groups. Results The operation time, the total time of puncture and the number of fluoroscopy were lower in the observation group than that in the control group. The patients in the observation group and the control group were treated before operation, 1 month after operation, 3 months after operation, 6 months after operation and there was no statistically significant difference in VAS score and ODI score between 12 months (P > 0.05). The patients in the observation group and the control group had no significant complication after operation. Although they had pain symptoms, they could be relieved by themselves or by drug treatment. Conclusion Ultrasonic volume navigation can enhance the accuracy of puncture and reduce the puncture time, and there is no significant complication after operation. The safety is better than that of C arm X-ray machine.

OBJECTIVETo investigate the clinical efficacy and safety of oxcarbazepine (OXC) suspension in children with focal epilepsy.

METHODSA total of 118 children aged 2-14 years, who were newly diagnosed with focal epilepsy between October 2009 and December 2011, were randomly divided into experimental group (n=60) and control group (n=58). The experimental group was treated with an orally suspension of OXC and the control group was orally administered with carbamazepine (CBZ) tablets. The two treatment regimens were compared in terms of clinical efficacy and safety.

RESULTSAfter 13 and 26 weeks of treatment, the experimental group had response rates of 75% and 72% respectively and seizure-free rates of 53% and 50%, and the control group had response rates of 71% and 66% and seizure-free rates of 50% and 43% respectively. There were no significant differences in the clinical efficacy between the two groups (P>0.05). After 26 weeks of treatment, the adverse event rates of the experimental and control groups were 18% and 40% respectively, with a significant difference between the two groups (P<0.05).

CONCLUSIONSOXC suspension has a comparable clinical efficacy to that of CBZ tablets in children aged 2-14 years who are newly diagnosed with focal epilepsy, but OXC suspension causes fewer adverse events and has higher safety.
