Objective To investigate the effect of the delayed interventional therapy to acute myocardial infarction prognosis. Methods Retrospective analysis was used to analyse the clinical data of 212 patients with myocardial infarction,there were 98 cases in the delayed PCI group,no line of PCI patients who had 114 cases were compared clinical data,medication compliance and clinical incidents situation. Results The clinical data and medication compliance between the two groups had no statistical difference (P＞0.05), delayed PCI group patients with heart failure symptoms have increased and the incidence of recurrent angina was significantly lower than that in OK PCI operation group(P＜0.05). Conclusion Delayed interventional treatment could improve the prognosis of patients with acute myocardial infarction.

Objective To investigate the expression of S100 and MMP-7 in human cholangiocarcinoma and their correlation with the perineural invasion of cholangiocarcinoma.MethodsThe expression of S100 and MMP-7 in 36 cases of human cholangiocarcinoma tissues and edjunct cancer tissues were analyzed by immunohistochemistry method,combining with the clinical documents analysis.ResultsThe positive rates of S100 and MMP-7 in 36 cases of human cholangiocarcinoma were 61.11%(22/36) and 83.33%(30/36),respectively,while in edjunct cancer tissues were 30.56%(11/36),0.0%(0/36).The positive rate of Hematoxylin and Eosin staining indicated perineural invasion was significantly correlated with S100(P0.05).There was a significant positive correlation between S100 and MMP-7(P

MicroRNAs (miRNAs)are involved in the pathological and physiological process of life activities,and some of them exist stably and abundantly in serum,plasma,and other body fluids.Previous studies have indicated that there are significant differences in the expres-sion patterns of circulating miRNAs between patients with viral hepatitis,liver fibrosis,liver cirrhosis,hepatocellular carcinoma,drug-in-duced hepatitis,and other hepatobiliary diseases at different disease stages.Among these circulating miRNAs,some can act as novel nonin-vasive biomarkers for the early diagnosis,disease progression,and prognostic evaluation of related diseases.The latest research advances in circulating miRNAs for the diagnosis of hepatobiliary diseases are reviewed.

Objective To explore the feasibility of la pa roscopic total extraperitoneal hernia repair without the use of the balloon diss ector. Methods Laparoscopic total extraperitoneal hernia repai r using no balloon dissector was completed in 10 cases of groin hernia from Nove mber 2003 to April 2004, including 7 cases of indirect inguinal hernia, 1 case o f occult indirect hernia combined with direct inguinal hernia, and 3 cases of di rect inguinal hernia (1 of which was recurrent hernia). Results All the 10 operations were successful. The mean operation time was 69.5 min, t he mean blood loss was 11 ml, the mean postoperative hospital stay was 2.1 days , and the mean duration to normal activities, 5.2 days.Complications included 1 case of disassociated inferior epigastric artery, 1 case of operation in wrong anatomic layer, and 1 case of laceration of the peritoneum, respectively. Follow -up observations for 1~6 months found no recurrence and neuropathic pain. Conclusions Laparoscopic total extraperitoneal hernia repair without the use of the balloon dissector is feasible, safe and effective.

Objective To evaluate the role of contrast enhanced ultrasound in treatment of ultrasound guided high intensity fo‐cused ultrasound ablation for uterine fibroids .Methods Forty eight women with uterine fibroids were allocated into contrast en‐hanced group(25cases ,42fibroids) and non contrast enhanced group(23 cases ,35 fibroids) .The average volume of fibroids and the non perfused volume and the fractional ablation and adverse effects between the tow groups were compared .Results Non perfused volume was observed in all fibroids of the two groups after high intensity focused ultrasound ablation through sulphur hexafluoride micro bubbles .The average non perfused volume was 19 .5(18 .2)cm3 and 22 .5(14 .5)cm3 ,fractional ablation was (78 ± 18)% and (87 ± 13)% of the uterus immediately after HIFU respectively .The average non perfused volume was 18 .6(18 .2)cm3 and 19 .5 (18 .7)cm3 ,fractional ablation was (85 .7 ± 15 .2)% and (87 .6 ± 8 .0)% of the uterus two days after HIFU .There was no signifi‐cant difference was observed in average non perfused volume and the fractional ablation between the two groups(P>0 .05) .During HIFU procedure ,more patients in non contrast enhanced group complained sacral pain than those in contrast enhanced group(P<0 .05) .Conclusion Contrast enhanced ultrasound is an accurate method in assessing the treatment effect of HIFU and could be safely used during HIFU treatment for uterine fibroids ,shorten therapy time ,and decrease side reaction .

Objective The research aimed to translate the English version of the Caregiver Preparedness Scale (CPS) into Chinese and to test the reliability and validity of the Chinese version of CPS in caregivers of stroke survivors. Methods Totally 176 stroke survivors and their caregivers were recruited and were investigated by the Chinese version of CPS. Results The internal consistency coefficient of the Chinese version of CPS was 0.925;the test-retest reliability was 0.807 (P<0.01). Factor analysis got one factor, which explained 61.647% of the total variance. The factor loading of each item was>0.4. Conclusions The Chinese version of CPS has been proved to be reliable and valid. It can be used as a valid tool for the measurement of caregiver preparedness in caregivers of stroke survivors.

Objective To translate the English version of the Exercise Self-Efficacy Scale (ESES) into Chinese and test the reliability and validity of the Chinese version of ESES in patients after stroke. Methods Totally 214 patients after stroke were recruited and were investigated by the Chinese version of ESES. Results The internal consistency coefficient of the Chinese version of ESES was 0.879. The split half reliability coefficient was 0.858(P<0.01). The test-retest reliability was 0.657. Item-total correlation coefficient ranged between 0.627 and 0.779 (P<0.01). Factor analysis got one factor, which explained 59.745%of the total variance, and the factor loading of each item was above 0.4. Using General Perceived Self-Efficacy Scale (GSES) as an external criterion, the Pearson correlation coefficient of ESES with GSES was 0.496. Conclusions The Chinese version of ESES has been proved to be reliable and valid. It can be used as a valid tool for the measurement of exercise self-efficacy in patients after stroke.

Objective To discuss the feasibility of laparoscopic closure of the internal ring and high ligation of the hernial sac in children with indirect inguinal hernia.Methods Laparoscopic closure of the internal ring and high ligation of the hernial sac was conducted in 21 children with indirect inguinal from January 2003 to December 2004 in this hospital.A 5-mm 30? laparoscope was introduced through the umbilicus.The internal ring and the posterior crus(PC) on the side of hernia were identified.A 3-mm dissection forceps was placed on the midline between the umbilicus and pubic symphysis.At the skin projection of the internal ring on the side of hernia,a round-tip needle with 3-0 Prolene suture grasped by a regular needle holder was passed directly into the abdominal cavity to suture the posterior crus and then penetrate out of the abdomen via the roof of the internal ring through the musculoaponeurotic arch of the transversus abdominis.Then the Prolene suture was cut off,and passed by using the Endoclose device into the extraperitoneal cavity at the skin projection of the internal ring.The dissection was continued from without outward around the sac to encircle the neck and an extracorporeal high circumferential ligation of the sac was finished.Results The operation was successfully completed in all the 21 cases.The operating time was 16~50 min(mean,32.9 min),the postoperative duration in hospital was 1~2 d,and the time to normal activity,1~4 d(mean,1.4 d),respectively.No postoperative bleeding,hematoma of scrotum,or incisional infection occurred.Follow-up checkups in the 21 cases for 1~24 months(mean,15 months) showed no recurrence.Conclusions Laparoscopic closure of the internal ring and high ligation of the hernial sac is a novel,feasible,reliable and effective herniorrhaphy for the treatment of pediatric indirect inguinal hernia.
