Objective To explore the clinical, radiological features and gene mutation of GALC gene in one child with globoid cell leukodystrophy (Krabbe disease). Methods The clinical and radiological data of a patient diagnosed with Krabbe disease through next-generation sequencing were retrospectively analyzed. Sanger sequencing was used to confirm the results. Results The patient was late infantile form with main manifestations of progressive psychomotor regression and convulsion. Brain MRI showed symmetric long T1 and long T2 signal changes in the white matter next to lateral ventricle angle, posterior limb of internal capsule, and the ministry of corpus callosum. The patient was found to have compound heterozygous mutations of c.1832T>C in exon 15 and c.979T>G in exon 9, which resulted in amino acid changes of p.L611S and p.F327V, respectively. Sanger sequencing results showed that the two heterozygous mutations were correspondingly inherited from his mother and father. Conclusions Next-generation sequencing technology is a useful tool for the detection of GALC gene mutation, which is valuable for definite diagnosis and differential diagnosis of Krabbe disease in clinical practice.

Background and purpose:Clinical data show that Endostar, a recombinant human endostatin, has the therapeutic beneift for patients with non-small cell lung cancer (NSCLC) while combined with chemotherapy or ra-diotherapy. However, the microenvironment changes induced by Endostar monotherapy in NSCLC is not yet clear. The purpose of this study was to prospectively study tumor vascular effects of Endostar monotherapy in patients with locally advanced or advanced NSCLC by dynamic contrast-enhanced perfusion computed tomography (CT perfusion, CT-p). Methods:Previously untreated patients with histologically or cytologically conifrmed locally advanced or advanced NSCLC were eligible. All patients received daily Endostar (7.5 mg?m2) for 14 days. CT-p scans were acquired at the baseline and post-treatment. CT-p parameters, such as blood lfow (BF), blood volume (BV) and permeability surface PS (area product), were measured in all patients.Results:Of all 7 patients enrolled, four were staged asⅢB and three as stageⅣ (2 with malignant pleural effusion, 1 with brain metastasis). The median BF, BV and PS values of baseline and post-treatment were 27.1/48.9 mL/100 mL/min, 86.8/84.8 mL/100 mL and 45.0/54.0 mL/100 mL/min, respectively. After administration of Endostar for 14 days , BF showed a signiifcant increase compared with that at baseline (P=0.028), whereas no signiifcant changes were found in BV (P=0.398) and PS (P=0.237) values.Conclusion:Our results suggest that Endostar monotherapy induces a signiifcant increase in BF whereas no signiifcant difference in BV and PS.

Objective:To assess whether Veronicastrum axillare (V. axillare) can ameliorate ethanol-induced gastric mucosal lesions in rats, reduce the production of pro-inflammatory cytokines, suppress apoptosis and improve local microcirculation disturbances.
Methods:Totally 48 male Sprague-Dawley rats were randomly divided into six groups, eight rats in each group. Rats in the normal group and the model group were administered with 0.9%normal saline respectively. Rats in the positive group and ranitidine group were administered with 0.18% ranitidine suspension by intragastric administration respectively. Those in the high dose V. axillare group, the medium dose V. axillare group and the low dose V. axillare group were administrated with V. axillare at the daily dose of 2.8 g/kg, 1.4 g/kg and 0.7 g/kg by intragastric administration. Gastric mucosal lesions were produced by intragastric administration of absolute ethanol. Water extract of V. axillare was successively injected for 14 d and last day was injected 1 h before ethanol administration. Gastric mucosal ulcer index and ulcer inhibitory rate were counted by improved Guth methods. The tissue sections were made for pathological histology analysis. Also, we measured the concentrations of tumor necrosis factor-α (TNF-α) and endothelin-1 (ET-1) in gastric mucosal, as an index of the pro-inflammatory cytokines, apoptosis and local microcirculation. Besides, the mRNA contents of TNF-αand ET-1 were measured to verify effects on gene expression by real-time fluorescent quantitative PCR.
Results: Water extract of V. axillare significantly ameliorated the gastric mucosal lesions induced by ethanol administration (P<0.01). Pro-inflammatory cytokines, TNF-αand ET-1 were increased after ethanol administration and significantly reduced by water extract of V. axillare. The expressions of TNF-αand ET-1 mRNA were also be inhibited by water extract of V. axillare.
Conclusion: Current evidences show water extract of V. axillare is effective for defending against ethanol-induced gastric mucosal lesions, significantly inhibiting the production of pro-inflammatory cytokines and the expressions of TNF-αand ET-1 mRNA, which may be useful for inhibiting apoptosis and improving local microcirculation.

Background and purpose:We investigated whether lfuorine-18 lfuorodeoxyglucose (18F-FDG) maximal standard uptake value (SUVmax) of the primary tumor (SUV-T), SUVmax of the regional lymph nodes (SUV-N) or the overall loco-regional lesion SUVmax (SUV-TOTAL) was related to survival of patients with stage Ⅲ non-small cell lung cancer (NSCLC) who received Cetuximab and combined definitive chemoradiotherpay. Methods:From September 2009 to July 2012, seventeen patients with unresectable stageⅢNSCLC receiving cetuximab with cisplatin/vinorelbine (NP) followed by concomitant NP and intensity-modulated radiotherapy (IMRT) at the Fudan University Shanghai Cancer Center were enrolled onto a prospectively study. All patients received positron emission tomography/computerized tomography (PET/CT) scans within 2 weeks before enrolment. Univariate analysis were used to assess the correlation between SUV-T, SUV-N, SUV-TOTAL, gender, age, histology, tumour-node-metastasis (TNM) stage, performance status (PS) as well as smoking status and survival. The factors which showed statistical signiifcance entered into multivariate Cox-regression model. Survival functions of different populations were estimated by Kaplan-Meier method and compared by Log-rank test. Results:In the univariate analysis, SUV-T, SUV-N, SUV-TOTAL, PS and smoking status were prognostic factors. The best cut-off values for SUV-T, SUV-N and SUV-TOTAL were 11, 11 and 20, respectively. Multivariate analysis revealed that SUV-TOTAL (P=0.012), SUV-T (P=0.025), and SUV-N (P=0.033) were independent predictors of survival with hazard ratio (HR) of 14.7, 11.2, and 6.2, respectively. Conclusion:Local, regional and locoregional maximal SUVs deifned by 18F-FDG PET-CT scanning may have a strong correlation with survival in this patients setting, which merits further study.

Objective: To evaluate the diagnostic value of a histologic scoring system in congenital biliary atresia and its prognostic relevance. Methods: From January 2017 to June 2018 at Children′s Hospital of Fudan University, 172 wedge liver biopsy specimens were obtained from infants with neonatal cholestasis [119 patients with congenital biliary atresia (CBA) and 53 patients with non-obstructive cholestasis as control]. A pathologist, single-blinded to the final diagnosis, made the histological diagnosis individually based on an 8-feature (portal ductal proliferation, bile duct reaction, bile plugs in portal ductules, liver fibrosis, edema in portal region, cholestasis, inflammatory cells infiltration in portal region, and ductal plate malformation), 21-point scoring system. Results: The main pathologic changes of biliary atresia were hepatocyte cholestasis, hyperplasia of bile ducts, fibrosis and infiltration of inflammatory cells in the portal area. There were significant difference in the degree of portal edema, bile duct hyperplasia and fibrosis between two groups (P<0.01). In addition, there were characteristic bile duct thrombosis in 97.5%(116/119) of the cases and abnormal development of bile duct plate in 9.2%(11/119) of the cases. Compared with non-CBA infant cholestasis group, the difference was statistically significant (P<0.05). The scoring system has high sensitivity, specificity (both 94.1%) and accuracy (94.3%) in the diagnosis of CBA. A score equal to or more than 11 points supported a diagnosis of CBA; whereas a score less than 11 points might suggest cholestasis. The degree of hepatic fibrosis and ductal plate malformation were related to prognosis. Conclusions The liver pathology scoring system (8-feature, 21-point) is more accurate in diagnosing CBA than previous methods, which may guide the clinicopathological diagnosis. This histological scoring system also helps to assess the prognosis of CBA.
