Objective To explore the effect of Fas, Fas ligand (FasL), soluble Fas (sFas) and their clinical significance in KD. Methods The expression of Fas, FasL in peripheral blood lymphocytes (PBLC) were detected with flow cytometery at acute and remission stages in patients with KD; and the serums Fas was detected by double antibody sandwich ELISA in the patients with KD at acute and remission stage, meanwhile erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) were also tested. Results The expression of Fas, FasL in PBLC in patients with KD at acute stage was (14.2±0.5)% and (1.61±0.09)% respectively , which were significantly lower than those at remission stage [(15.7±0.5)%, (1.95±0.09)% respectively (P<0.05 and P<0.01)]. The expression of Fas in PBLC in the patients with KD at acute and remission stage was both significantly lower than that in normal control group (20.8±0.5)% (P<0.01 both);The expression of FasL in PBLC in patients with KD at acute and remission stage was both significantly lower than that in normal control group (20.8±0.5)% (P<0.01 both); the serum sFas in patients with KD at acute and remission stage was (1906±55)μg/L and (1622±52)μg/L respectively , which was significantly higher than that in normal control group (1151±51)μg/L (P<0.01 both); the serum sFas at acute stage was obviously higher than that at remission stage (P<0.01); there was positive correlation between sFas and ESR, CRP (P<0.01 both). Conclusion There are abnormal expressions of Fas/FasL in PBLC and sFas in patients with KD. Fas/FasL is lower and sFas is higher than that of the controls. The abnormal expression of Fas/ FasL in lymphocytes and the apoptosis triggered by sFas are probably involved in the immunological aberrance and pathogenesis of KD. sFas may be used as a marker to evaluate the disease activity and therapeutic efficacy.

OBJECTIVETo evaluate postoperative renal function in children with congenital moderate or severe hydronephrosis.

METHODS99mTc-labeled diethylenetriaminepenta-acetic acid scintigraphy was performed in 50 children with unilateral moderate or severe hydronephrosis to determine postoperative renal function. We also analyzed the factors influencing renal function recovery.

RESULTSAverage postoperative renal function in 50 cases was 40.62% +/- 10.09%. Among them, 32% of patients had nearly normal renal function and differentiated renal function reached up to 45%. Average preoperative and postoperative renal function in 25 cases was 23.89% +/- 11.65% and 39.33% +/- 8.59% respectively and the increase of renal function was about 15.44% +/- 11.18% (P = 0.0003). Renal parenchyma thickness was negatively correlated with postoperative renal function (r = -0.62, P = 0.0009). The follow-up period was positively correlated with postoperative renal function (r = 0.58, P = 0.0026). The patients' age had no correlation with renal function recovery (r = -0.05, P = 0.80). Recovery of renal function in hydronephrosis with extrarenal pelvis was greater than that in hydronephrosis with intrarenal pelvis (P = 0.016).

CONCLUSIONSPostoperative renal function in children with moderate or severe hydronephrosis can recover to normal. Recovery of renal function was more obvious in hydronephrosis with thinner renal parenchyma, longer follow-up period and extrarenal pelvis.

The medical-industrial fusion training model combines the knowledge and technology of medical and engineering disciplines in the training of oncology graduate students, which can help accurate diagnosis and treatment of tumors, promote cooperation and innovation in oncology research, as well as promote the cultivation and exchanges of composite and innovative medical talents in oncology, promote the innovation and development of oncology diagnostic and treatment technology, and improve the survival rate and quality of life of oncology patients. This paper discusses the application of medical-industrial fusion training model in the training of o ncology professionals, and explores the new teaching mode of medical-industrial fusion thinking in the cultivation of complex and innovative medical talents in oncology under the background of "new medical science".

With the deepening of China's medical reform, people's demand for health is growing, which promotes the construction of "new medicine" and puts forward higher requirements for the cultivation and education of medical students. Undergraduate medical education is a crucial period for the growth of medical students, and how to do a good job in undergraduate teaching under the background of "new medicine" is currently a research hotspot. The clinical teaching stage is an important period for medical students to fully understand clinical disciplines and cultivate their understanding of specialties. Therefore, we should explore new teaching methods and means to adapt to the needs of the new era. In the context of "new medicine", the medical-engineering fusion diagnosis and treatment technology has become an important trend in the clinical diagnosis and treatment of oncology. In order to adapt to this change, clinical teaching and teaching management in oncology also need new exploration and research. Taking the clinical teaching of oncology as an example, this article discusses how to cultivate medical students' thinking of medical-engineering fusion.
