Objective To explore the specific features and value of spiral CT delay repeated scanning in diagnosis of cerebral schistosomiasis granuloma.Methods The spiral CT dynamil scanning material of 49 cases of intracerebral schistomiasis proved by pathology and clinic were retrospectively analyzed.Results There was no focus enhancement within ninety seconds post contialed;Focus showed a beginning enhancement was begun within the second to the fifith minutes and the peak enhancement was within the fifth to the fifteenth minutes mixed together like a ball gradually ;Focus enhancement decreased with time within the fifteenth to the twentieth minutes and disappeared after the twenty-fifth minutes.Conclusion Spiral CT delay repeated scanning had specific features in diagnosis of cerebral schistosomiasis granuloma,the diagnosis accuracy rates was 100%.

Objective Mesenteric panniculitis is an idiopathic , uncommon disease involving the adipose tissue of mesentery .The etiology , diagnosis and treatment are still unnoticed .We thus reported a case series to improve the understanding of this rare disorder .Methods We retrospectively analyzed the clinical data of 12 patients with mesenteric panniculitis including manifestation , diagnosis, treatment and prognosis.Results We found a male predominance (M∶F 3∶1) with the median age of 58 years old at diagnosis.The most common symptom was abdominal pain (9/12), followed by abdominal distension (3/12) and weight loss (3/12).Physical examination was unremarkable in the majority of patients (8/12).C reactive protein (9/12) and erythrocyte sedimentation rate (10/12) were normal in majority of patients.CT findings were of much diagnostic value .All patients had small intestinal mesentery involvement and multi-nodular appearance with increased fat density .Pseudo-capsule sign ( 8/12 ) and fat halo sign (6/12) were common.Pathological diagnosis was obtained in 4 cases showing fat tissue inflammation with local necrosis and fibrosis .Six cases all received prednisone , 2 with combined cyclophosphamide , 1 with azathioprine, 1 with tripterygium wilfordii .Short-term clinical response was achieved in all cases , but two patients relapsed .Conclusions Mesenteric panniculitis occurs predominantly in middle-aged and elderly . Abdominal pain is the leading symptom .Inflammatory markers are often normal while computed tomography is the most important diagnostic tool .Surgery combined with cortical steroid and immunosuppressant agents is effective.

Objective To explore the clinical prognosis and efficacy of adjuvant therapy with imatinib of postoperative patients with gastric intermediate-risk gastrointestinal stromal tumor (GIST).Methods The clinicopathological data and follow-up data of 93 gastric intermediate-risk GIST cases from Jan 2005 to Dec 2016 at Union Hospital were analyzed retrospectively.Univariate and multivariate analysis were performed to assess the prognostic factors.Results There were 93 patients undergoing complete GIST resection with 42(45％) cases receiving post-op imatinib 400 mg/d for targeted therapy.The median target therapy period was 12 (6-72) months.86％ (80 cases) patients were followed up for 46 (6-120) months.The 1-,3-,5-year recurrence-free survival rate (RFS) of the whole group were 100％,91.5％,88.5％ respectively.Multivariate analysis revealed that mitotic count (P =0.040,RR =6.078,95％ CI:0.541-68.274) and neutrophil-lymphocyte ratio (NLR) (P =0.036,RR =6.102,95％ CI:0.782-47.632) were prognostic risk factors of RFS.For those mitotic count ＞ 2/50 HPF and NLR ＞ 2.3,adjuvant therapy with imatinib significantly increases RFS.Conclusion Mitotic count and NLR were independent risk factors of RFS in gastric intermediate-risk GIST.For those with mitotic count ＞ 2/50 HPF and NLR ＞ 2.3,postoperative adjuvant therapy with imatinib helps improve the prognosis.
