OBJECTIVETo evaluate the possibility of radial artery pressure and waveform as a convenient definition of pulsatile flow and the the effect of pulsatile perfusion during cardiopulmonary bypass (CPB) procedures.
METHODSFrom March 2008 to December, Eighty patients underwent open heart surgery were randomly divided into a pulsatile group (P, n=45) and a nonpulsatile group (NP, n=35). Monitored by radial artery pressure and waveform, the pulsatile low was applied from the point of the aortic cross-clamp until its release in P group. A P group of patients whose radial artery pressure and waveform revealed "double peak" or "single peak" (>30 mm Hg, 1 mm Hg=0.133 kPa) were compared with NP group. Parameters examined were lactate, urine volume, high sensitivity C reactive protein, blood urea nitrogen, creatinine, blood uric acid, lactate dehydrogenase, glutamic oxalacetic transaminase, ratio of urine for occult blood test, prothrombin time and tracheal intubation time.
RESULTSThe waveform with "double peak" or "single peak" (>30 mm Hg) presented in 35 (77.78%) in P group. The urine volume during CPB was significantly higher in P group. The lactate (P<0.01) during CPB, high sensitivity C reactive protein (P<0.05), increasing extend of lactic acid dehydrogenase (P<0.05) and the prothrombin time (P<0.01) after CPB were significantly lower in P group. The blood uric acid after CPB was increased in P group and decreased in NP group.
CONCLUSIONSEffective pulsatile flow can be generated by optimization of equipment and adjustment of pulsatile parameter. The radial artery pressure and waveform is a convenient definition of pulsatile flow. The pulsatile flow is predominant monitored by radial artery pressure and waveform.

Journal of Xinxiang Medical College 2018;35(6):525-527
Objective To analyze the clinical features of invasive Klebsiella pneumoniae liver abscess syndrome (IKLAS). Methods The clinical data of IKLAS patients diagnosed in China-Japan Friendship hospital from January 2010 to October 2017 was analyzed retrospectively. Results There were 9 patients with IKLAS including 6 males and 3 females aged (56. 77 ± 10. 28)years old. Four cases with diabetes mellitus,one case with impaired glucose tolerance,and two cases with cholelithiasis history. Single abscess (7 / 9),multiple abscess(2 / 9). Involved organs:lung(7 / 9),eyes(3 / 9),soft tissue (1 / 9),joint(1 / 9)and nerve system(1 / 9). Laboratory test showed an elevation of the white blood cell count (8 / 9),the al-anine aminotransferase (9 / 9)and the PCT (7 / 9 ),and only one ESBL positive Klebsiella pneumonia. Three cases with en-dophthalmitis lost their sight,and one with meningitis died. Conclusion IKLAS is common in people with diabetes,and it may be associated with multiple sites of metastasis of the body and lungs are the most involved organ.

BACKGROUNDIntravascular ultrasound (IVUS) examination can provide useful information during endovascular stent graft repair. However, its actual clinical utility in thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (type B-AD) remains unclear, especially in complicated aortic dissection. We evaluated the effect of IVUS as a complementary tool during TEVAR.
METHODSFrom September 2011 to April 2012, we conducted a prospective cohort study of 47 consecutive patients with "complicated" type B-AD diagnosed. We divided the patients into two groups: IVUS-assisted TEVAR group and TEVAR using angiography alone group. The general procedure of TEVAR was performed. We evaluated the perioperative and follow-up events. Patient demographics, comorbidities, preoperative images, dissection morphology, details of operative strategy, intraoperative events, and postoperative course were recorded.
RESULTSA total of 47 patients receiving TEVAR were enrolled. Among them (females, 8.51%; mean age, 57.38 ± 13.02 years), 13 cases (27.66%) were selected in the IVUS-assisted TEVAR group, and 34 were selected in the TEVAR group. All patients were symptomatic. The average diameter values of IVUS measurements in the landing zone were greater than those estimated by computed tomography angiography (31.82 ± 4.21 mm vs. 30.64 ± 4.13 mm, P < 0.001). The technique success rate was 100%. Among the postoperative outcomes, statistical differences were only observed between the IVUS-assisted TEVAR group and TEVAR group for total operative time and the amount of contrast used (P = 0.013 and P < 0.001, respectively). The follow-up ranged from 15 to 36 months for the IVUS-assisted TEVAR group and from 10 to 35 months for the TEVAR group (P = 0.646). The primary endpoints were no statistical difference in the two groups.
CONCLUSIONSIntraoperative IVUS-assisted TEVAR is clinically feasible and safe. For the endovascular repair of "complicated" type B-AD, IVUS may be helpful for understanding dissection morphology and decrease the operative time and the amount of contrast used.

Objective: To analyze associations of MRI-lesions and clinical features with disability in patients
with multiple sclerosis (MS) in Shanghai, China. Methods: We studied patients with MS, identified
from a survey in Shanghai, whose sites of lesions in the CNS was based on the MRI examinations.
Associations between MRI-lesions, various clinical variables and the severity of disability were analyzed
with univariate and multivariate logistic regression analysis. Results: There were 210 patients in this
study. The disability of the patients with lesions confined to the spinal cord was significantly more
severe than those with lesions in the brain (p < 0.008). Current age (OR: 1.041, 95% CI: 1.007~1.077),
MS duration (OR: 1.082, 95% CI: 1.011~1.159) and MRI-lesions in the spinal cord (OR: 2.441, 95%
CI: 1.039~5.737) were significantly associated with severity of disability on multivariate logistic
regression analysis.
Conclusion: MRI-lesions in the spinal cord, older age, a longer MS duration were significantly
associated with a more severe disability in this MS study in Shanghai China.
