Objective To investigate the clinical features of infantile diarrhea with intussusception,improve the level of diagnosis and treatment,reduce the misdiagnosis and delayed treatment.Methods The clinical data of 23 cases with infantile intussusception were retrospectively analyzed.Results Twenty-three cases of children with diarrhea symptoms at the beginning of the disease had different degree,12 cases characterized by vomiting,diarrhea,fever and other symptoms of acute gastroenteritis,5 cases stool were mucous pus blood,6 cases for blood in the stool.Five cases were confirmed within 24 h of the diagnosis (3 cases with air enema reduction of intussusception,2 cases with manual reduction),11 cases were confirmed at 24 h to 3 d of the diagnosis and operated,7 cases were confirmed more than 3 d of the diagnosis and operated.Except 1 cases was died from shock,22 cases were cured.Conclusion Infantile intussusception atypical symptoms,illness development is rapid,in critical condition,easy misdiagnosis,missed diagnosis,should actively improve the standard of diagnosis.,early diagnosis,so as not to delay treatment.

In this paper, 2 cases of collagen Type Ⅲ glomerulopathy were analyzed. The clinical manifestations mainly included nephrotic syndrome, proteinuria, hypertension and renal dysfunction. One patient showed that the complement factor H-related protein 5 (CFHR5) gene was likely a disease-causing mutation. The pathological examination of renal tissues showed hyperplasia of mesangial matrix, sub-endothelial insertion, and double-track formation. Immunohistochemistry of Type III collagen was positive. Electron microscopy revealed that massive collagen fibers (40-70 nm in diameter) deposited in the mesangial matrix and basement membrane. As for the follow-up results, the normal renal function had kept steady and the proteinuria was moderate in 1 case treated with angiotensin Ⅱ receptor blocker. Due to other system disease, another case developed into acute kidney injury and then received hemodialysis. The clinical manifestations of collagen Type Ⅲ glomerulopathy was atypical, the light microscope pathological features were various, and the disease was mainly diagnosed by electron microscopy and immunohistochemistry.

OBJECTIVES: To evaluate the value of thrombospond in Type I domain-containing 7A (THSD7A) and M-type phospholipase A2 receptor (PLA2R) in primary membranous nephropathy (PMN) and to explore the relationship between their antibody levels and prognosis. METHODS: Renal tissues in 128 patients with membranous nephropathy in the Second Xiangya Hospital of Central South University were collected from February 2015 to August 2017, including 108 patients with primary membranous nephropathy (PMN group) and 20 patients with secondary membranous nephropathy (SMN) (SMN group). Indirect immunofluorescence method was used to detect the expression of PLA2R antigen in kidney tissues,and the glomerular expression of THSD7A antigen was examined by immunohistochemistry and indirect immunofluorescence. The serum levels of anti-PLA2R antibodies and THSD7A antibodies were also detected by ELISA. According to the results of PMN examination,the patients were also divided into a PLA2R-related membranous nephropathy group and a THSD7A-related membranous nephropathy group. RESULTS: The positive rate of PLA2R in the renal tissues in the PMN group was higher than that in the SMN group (78% in the PMN group, 35% in the SMN group, <0.01),while the positive rate of anti-PLA2R antibody in the PMN group was also higher than that in the SMN group (50% in the PMN group, 25% in the SMN group, <0.05).The serum level of anti-PLA2R antibody was positively correlated with 24 h urine protein (=0.254, <0.05) and negatively correlated with serum albumin (=-0.236, <0.05). The expression of THSD7A was positive in glomeruli in 7 cases of the PMN group (6%) by immuno-histochemistry, and which was positive in 1case of the SMN group (5%).The serum levels of anti-THSD7A antibody in the PMN group were higher than those in the SMN group [(0.49±0.26) pg/mL in the PMN group,(0.34±0.27) pg/mL in the SMN group, <0.05]. There was no difference in the clinical characteristics between the PLA2R-related membranous nephropathy group and the THSD7A-related membranous nephropathy group. CONCLUSIONS PLA2R and THSD7A are the target antigen of PMN, and the associated autoantibodies are helpful for the differential diagnosis of PMN. The anti-PLA2R antibody levels can reflect the severity of the disease and evaluate the effect of treatment. The incidence of THSD7A membranous nephropathy is low, and monitoring the serum anti-THSD7A antibody levels can assess patients' condition and predict disease outcome.
