Case based learning was introduced in the teaching ward round on oncology. Our heuristic, interactive, discussion-style teaching model was focused on real clinical cases, by raising questions to discuss strategies for solving problems. Therefore, we can foster clinicians' ability of solving problems, their innovative spirit and team-work spirit so as to meet the requirements of multidisciplinary treatment in new era oncology.

Objective To explore the possibility of anterior open reduction and internal fixation to treat the lower cervical irreducible dislocation. Methods 15 cases of lower cervical irreducible dislocation were treated by the anterior open reduction and internal fixation, 11 cases were male and 4 cases were female, 10 cases were unilateral facet locked and 5 eases were bilateral facet locked which were confirmed by the MRI and CT scan. All the cases were failed to the skull traction before operation and received anterior open reduction and plate fixation, and interver-tebral fusion. All the cases were followed up, the recovery of neurological function and the fusion rate were evaluated. Results 15 cases were completely reduction and none of them got a worse neurological function. Conclusion The treatment effect of anterior open reduction and fixation for the lower cervical irreducible dislocation were good.

Background Various studies demonstrated that the apoptosis of lens epithelial cells(LECs) is associated with the overexpression of the c-myc gene in LECs induced by galactose.Inhibiting the abnormal expression of the c-myc gene in LECs is an effective approach to mitigate the pathogenesis and development of cataract.Objective The goal of this study is to investigate the inhibitory effects of c-myc antisense oligodeoxynucleotide(c-myc ASODN) on the apoptosis of LECs in the eye with galactose-induced cataract.Methods Galactose-induced cataract models were established by the retrobulbar injection of 0.2 mL of 20% galactose once per day.Lipo-antisense oligodeoxynucleotide(Lipo-ASODN,0.2 mL) was retrobulbarly injected 4 hours after the injection of galactose at one-day intervals.The animals were sacrificed and lenses were obtained to evaluate the apoptosis of LECs and the effect of c-myc ASODN on LECs apoptosis induced by galactose was examined by TUNEL assay after 7,14 and 24 days.The ultrastructural changes of LECs were examined under the transmission electron microscopy(TEM).Results A significant difference in the apoptotic rate of LECs was found among the 7 day,14 day and 24 day groups(F_(7 days)=3 418.495,P＜0.01;F_(14 days)=1137.555,P＜0.01;F_(24 days)=2198.871,P＜0.01).The apoptotic rate of LECs in the galactose group was markedly higher than that in the normal saline solution group 7 days,14 days and 24 days after the experiment(P＜0.01).The apoptotic rate of LECs in the galactose+lipo+ ASODN group significantly declined in comparison to the galactose group after 7 days,14 days and 24 days(P＜0.05).TUNEL assay showed the condensation,breakage and irregularity of the nuclei of apoptotic cells in the galactose group.The destruction of the ultrastructure of the cells and organelles were observed under the transmission electron microscope.Conclusion Galactose induces apoptosis of LECs in cataractogenesis.C-myc ASODN inhibits apoptosis of LECs induced by galactose.

Objective:To investigate the role of miR-146a in the pathogenesis of systemic juvenile idiopathic arthritis (sJIA) and its clinical significance.Methods:This article is a prospective clinical cohort study.Twenty-six patients with sJIA (14 cases of initial active group and 12 cases of stable group), 15 patients with multijoint juvenile idiopathic arthritis (JIA) and 15 patients with oligojoint JIA diagnosed in the Department of Rheumatology and Immunology of Anhui Provincial Children′s Hospital from June 2018 to December 2020 were enrolled.Twenty healthy controls from the out-patient clinic were also recruited.The expression level of miR-146a in peripheral blood mononuclear cells (PBMCs) of research objects was detected by real-time fluorescence quantitative polymerase reaction (qPCR), and the serum levels of interleukin (IL) - 6, tumor necrosis factor (TNF) - α and IL-1β in sJIA patients and healthy controls were detected by enzyme-linked immunosorbent assay.The expression levels of miR-146a in PBMCs and cytokines among different groups were compared by analysis of variance. Pearson correlation analysis was used to analyze the correlation of the relative expression level of miR-146a in PBMCs with clinical inflammatory indexes and serum cytokines in sJIA patients. Results:(1) The expression level of miR-146a in PBMCs of early sJIA patients was significantly higher than that in the multijoint JIA group and oligojoint JIA group (8.77±3.15 vs.4.40±1.59, 2.55±1.15, t=6.27, 14.23; all P<0.05). The expression level of miR-146a in PBMCs of sJIA active patients was significantly higher than that in sJIA stable patients (8.77±3.15 vs.3.63±1.37, t=10.27, P<0.05). There was no significant difference in the expression level of miR-146a between the sJIA stable group and healthy control group ( P>0.05). (2) The expression levels of IL-1β, IL-6 and TNF-α were significantly higher in sJIA active patients group than those in sJIA stable group[(58.56±17.47) ng/L vs.(26.32±10.54) ng/L, (73.72±11.16) ng/L vs.(23.20±9.12) ng/L, (70.93±19.97) ng/L vs.(24.25±9.49) ng/L, all P<0.05]. There was no significant difference in the expression levels of IL-1β, IL-6 and TNF-α between the sJIA stable group and healthy control group(all P>0.05). (3)The expression of miR-146a in PBMCs of sJIA patients was positively correlated with serum ferritin levels, platelets, erythrocyte sedimentation rates, C-reactive proteins, IL-1β, IL-6 and TNF-α( r=0.542, 0.433, 0.329, 0.306, 0.333, 0.342, 0.319, all P<0.05). Conclusions:miR-146a may be involved in the inflammatory process of sJIA disease.miR-146a can well distinguish sJIA from multijoint JIA and oligojoint JIA.TNF-α, IL-1β and IL-6 are involved in sJIA inflammatory responses.
