Objective To investigate the MR imaging (MRI) appearances of postoperative residual liver after hepatic resection for hepatocellular carcinoma (HCC) and the MRI features of tumor recurrences.Methods Twenty patients with previous surgical resection of HCC underwent MR examination of upper abdomen for routine follow-up study or due to clinical suspicion of tumor recurrence. MRI protocol included T1W axial unenhanced images and Gadolinium-enhanced sequences, Gadolinium-enhanced VIBE sequence, unenhanced T2W axial images and coronal TrueFisp sequence.Results Thirteen patients showed normal edge of surgical resection, while 6 patients demonstrated MR signs of incision edge recurrence of HCC and 1 patient was suspicious of tumor recurrence at the incision edge. Among the 20 patients, 12 had MRI features of tumor recurrence of the residual liver, including invasion of left, right and common hepatic ducts 3 cases. Three patients had metastatic lymphadenopathy in portal hepatis, portacaval space and retroperitoneal space. Two patients showed extensive tumor implantation of peritoneum and mesentery. Conclusion MRI is effective in differentiating normal surgical incision edge of residual liver from tumor recurrence. It is also very useful for the early detection of intra-hepatic and extra-hepatic tumor lesions.

A suitable liquid chromatography quadrupole time-of-flight mass spectrometric (LC–Q-TOF–MS) method was developed for separation and characterization of related substances in bacitracin test drug. The separation was performed on LiChrospher RP-18 column using methanol as mobile phase A and 0.2% ammonium acetate buffer solution as mobile phase B in gradient elution. A total of 12 related substances were detected through high resolution mass spectrometric determination in a positive electrospray ionization mode. They were identified as co-existing active components and degradation products of bacitracin through the analysis and elucidation of both the protonated parents and the product ions of all the related substances and their fragmentation pathways were also proposed.

Avulsion injury of the flexor digitorum profundus tendon from distal phalanx is considered as a rare injury. Accrording to the classification by Leddy and Pacter, this case is Type III, which is a large bony fragment retained by the tendon. The distal pulley prevents retraction beyond the middle phalanx. We are reporting a case with brief review of literatures.

PURPOSE: The aim of this study was to evaluate the clinical manifestations, contact history, and status of tuberculosis contact investigations in school-age children and adolescents with pulmonary tuberculosis (TB) at two centers. METHODS: This study was conducted with 54 patients in the age ranging from 10 to 18 years, who were diagnosed with pulmonary TB at the Pusan National University Hospital and Pusan National University Children's Hospital, January 2008 to December 2012. We retrospectively reviewed the medical records of the patients. RESULTS: The median age of the patients was 16 years old; 11 patients were aged 10 to 14 and 43 patients were aged 15 to 18. Among 54 patients, 19 had history of contact with pulmonary TB, 10 had contact with house members (household), and remaining 9 had contact with classmates (non-household). One out of 10 patients who had household contacts and 6 out of 9 patients who had non-household contacts were evaluated with contact investigation after the exposure to pulmonary TB. Among 7 patients who were evaluated with contact investigation, 3 were diagnosed with active pulmonary TB, 1 had latent tuberculosis infection (LTBI), and 3 had no evidence of TB or LTBI. The median period of diagnosis after the exposure to active pulmonary TB was 2 years in patients with household contacts and 0.23 years in patients with non-household contacts. CONCLUSION: This study suggested that if the contact investigation conducted properly, it would be helpful for early diagnosis and prevention of pulmonary TB.

Objective To evaluate the clinical efficacy and safety of domestic Sirolimus-eluting stents (Firebird) and imported Zotalimus-eluting stents ( Resolute) in the treatment of patients with unprotected left main coronary artery disease ( ULMCA) . Methods We retrospectively enrolled 76 patients with ULMCA treated by percutaneous coronary intervention (PCI) under the guidance of IVUS in our hospital. According to the different stents used in the procedure, the patients were divided into two groups: Domestic Sirolimus-Eluting Stents group (Firebird group, n = 42) and Imported Zotarolimus-Eluting Stents group (Resolute group, n = 34) . We analyzed the baseline characteristics, coronary artery lesion characteristics, stenting strategies and any changes in left ventricular ejection fraction ( LVEF) in both groups and investigated the long-term clinical outcomes. Results There were no significant differences in the baseline characteristics, the SYNTAX scores of the coronary artery lesion and the rate of complete revascularization between the two groups. Compared with that in Firebird group, there were more cases involving the distal left main (79. 4% vs. 45. 2% , P ﹤ 0. 05) and more patients using two stents strategies (29. 4% vs. 7. 1% , P ﹤ 0. 05) in the Resolute group. The change in LVEF post-PCI had no difference between the two groups. The patients were followed up for a mean of (23. 3 ± 10. 7) months. During the follow-up period, the occurrence of MACCE had no significant difference between the two groups. In the Firebird group, there were one sudden cardiac death, one nonfatal myocardial infarction, one stroke and five patients with recurrence of angina pectoris. In the Resolute group there were one sudden cardiac death, one target lesion revascularization and four patients with recurrence of angina pectoris. Conclusions Compared with the imported Zotalimus-Eluting Stents, the domestic Sirolimus-Eluting Stents are safe and effective in the treatment of patients with unprotected left main lesions under the guidance of IVUS. The two kinds of stent showed similar long-term clinical outcomes.
