Small bowel intusssusception is relatively rare in children and the manifestation is always atypical.Abdominal ultra-sonography conduces to final diagnosis.It can be classified into transient and persistent small bowel intussusception with their own clinical characteristics respectively.This article systematically reviews the clinical features and treatment advances of small bowel intussusception in children.

OBJECTIVETo find out the morphological regularity of root canal in the primary tooth.

METHODSThrough transparent specimen of a set of deciduous teeth, the shape of root canal was observed under stereomicroscope.

RESULTSAmong the deciduous anterior teeth, 92% were single canal except for one single-double mixed canal. Maxillary deci-duous molar had 3 canals and mandibular deciduous molar had 4 canals, lateral canal and anastomosis between the root canals were popular in deciduous molar.

CONCLUSIONDeciduous root canal morphology is simple in anterior teeth and comparatively complex in molar.

Wnt signaling pathway plays an important role in development.In the process of intestinal development, Wnt affects differentiation, proliferation and function of different intestinal cell types, and its abnormal regulation could lead to the occurrence of various diseases.The effect of Wnt on intestinal development, physiology and pathology will be discussed in this paper.

Objective:To systematically evaluate the effectiveness of Kunxian capsule related regimens for patients with lupus nephritis(LN)in order to provide a reference basis for treatment strategies for LN patients.Methods:The computer searched the rele-vant studies of Kunxian capsule in PubMed,Web of Science,Cochrane Library,CBM,CNKI,Wanfang and VIP databases on the treatment of LN,the limited time for the establishment of the database is April 6,2022,and used R 4.0.2 software and Revman 5.3 software for Meta-analysis.Results:Four RCTs with 1 cohort study including 310 patients were finally included.The results of the Me-ta-analysis showed that:In terms of 24 h urinary protein and SLEDAI score,Glucocorticoid+Cyclophosphamide+Kunxian capsule achieved the best result after treatment;in terms of Scr,IgE,and IgG,the levels of each index were significantly lower in Glucocorti-coid+Cyclophosphamide+Kunxian capsules than in Glucocorticoid+Cyclophosphamide(P<0.05).Conclusion:The 5 regimens may work best as Glucocorticoids+Cyclophosphamide+Kunxian capsules in terms of clinical efficacy in treating LN patients.Because of the quality and quantity limitations of the included studies,more high-quality studies are needed for validation.
