Objective:To study the effect of Xihuang Capsule combined with GP regimen on the serum levels of tumor necrosis factor-oα (TNF-α),vascular endothelial growth factor (VEGF),matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) of patients with advanced breast cancer.Methods:88 patients with advanced breast cancer admitted in our hospital from March 2014 to February 2015 were selected and divided into the observation group and the control group according to the order of admission.The control group was treated by the GP program,the observation group was given Xihuang capsule combined with GP regimen.The serum levels of TNF-α,VEGF,MMP-2 and MMP-9 in the two groups were compared before and after treatment.The clinical efficacy and incidence of side effects were analyzed.Results:The total effective rate of observation group was significantly higher than that of the control group [84.09％ (37/44) vs 50.00％ (22/44)] (P＜0.05).There was no significant difference in the serum levels of TNF-α,VEGF,MMP-2 and MMP-9 between the two groups before treatment (P＞0.05).After treatment,the serum TNF-α,VEGF,MMP-2 and MMP-9 levels were significantly lower than those before treatment (P＜0.05).The serum levels of TNF-α,VEGF,MMP-2 and MMP-9 of observation group were significantly lower than those of the control group (P＜0.05).There was no significant difference in the incidence rate of nausea and vomiting between the two groups (P＞0.05).The incidence ofalopecia,diarrhea,abnormal liver function,decreased appetite,anemia and leukopenia in the observation group were significantly lower than those of the control group (P＜0.05).Conclusion:Xihuang Capsule combined with GP regimen could more effectively reduce the levels of serum TNF-α,VEGF,MMP-2 and MMP-9 of patients with advanced breast cancer than GP regime alone with higher safety.

To retrospectively analyze the clinical data of a case of shunt nephritis as the manifestation of systemic lupus erythematosus (SLE) admitted to the Department of Nephrology, Wuhan Children′s Hospital in November 2019, and to analyze its clinical characteristics and diagnosis and treatment through literature review.A 11-year-old female child was diagnosed as SLE for fatigue after exercise, onset of gross hematuria, auxiliary detection of anemia, hematuria albuminuria, hypocomplementemia, positive test for the antinuclear antibody, positive test for anti-human globulin, and hyperplastic lesions detected by renal pathology.However, immunosuppressive therapy was not effective.Considering the previous history of congenital hydrocephalus and ventricular and atrial shunt and through literature review, the patient was finally diagnosed was shunt nephritis.After active anti-infection and ventriculoatrial shunt to ventriculoperitoneal shunt, the symptoms were relieved.Shunt nephritis is a rare complication caused by ventricle shunt tract infection.Early recognition and treatment can avoid misdiagnosis and improve prognosis.

Objective:To assess the efficacy of Rituximab (RTX) in treating children with refractory nephro-tic syndrome.Methods:A retrospective study was carried out.Twenty-two children diagnosed with refractory nephrotic syndrome in the Department of Nephrology of Wuhan Children′s Hospital, Tongji Medical College, Huazhong University of Science and Technology from November 2018 to November 2020 were included in the study.All patients were treated with RTX.Patients with CD 19+ B lymphocytes≥1% total lymphocytes in peripheral blood were supplemented with one dose of RTX (375 mg/m 2), and each patient received 3-4 doses of RTX on average.The patients were treated with Mycophenolate mofetil after early discontinuation of calcineurin inhibitors (CNI). The Kaplan-Meier method was used to analyze the proteinuria relapse-free rate and the incidence of frequently recurrent nephrotic syndrome or steroid-dependent nephrotic syndrome in children after RTX treatment.The relapse times before and after using RTX were analyzed by the Wilcoxon signed rank test.Besides, the body mass indexes (BMI) and height of children before and after RTX treatment were compared by the rank sum test. Results:Of 22 patients studied, 20 patients accomplished the therapeutic protocol.One-year and two-year proteinuria relapse-free survival rates were 85% and 40%, respectively.The recurrence rate was reduced under the discontinuation of CNI.Compared with those before RTX treatment, the BMI and height of all children were significantly improved at 1 year and 2 years after RTX treatment (all P<0.05). However, no significant improvement was observed between 1 or 2 years after RTX treatment (all P>0.05). Conclusions:The use of RTX can effectively reduce the recurrence rate of refractory nephrotic syndrome even when hormones and other immunosuppressants are discontinued.At the same time, RTX can significantly improve the BMI and height of children.RTX is safe and effective for treatment of refractory nephrotic syndrome.

Objective:To investigate and analyze the clinical phenotypes and genotypes in children diagnosed with nephronophthisis (NPHP), and to provide references for clinical diagnosis.Methods:Clinical data of 9 children with NPHP diagnosed by genetic testing in the Department of Nephrology, Wuhan Children′s Hospital from April 2017 to January 2022 were retrospectively collected. The clinical characteristics and genetic test results were analyzed.Results:The median onset age was 11.2(3.4, 14.2) years old in 9 patients, including 5 females and 4 males. There were 8 cases of glomerular proteinuria, 8 cases of renal tubular proteinuria, and 7 cases of reduced urinary gravity in 9 patients. All the children had varying degrees of impaired renal function at the time of diagnosis. Seven cases entered chronic kidney disease (CKD) stage 5, 1 case entered CKD stage 3, and 1 case entered CKD stage 4 at the time of diagnosis. All the children had renal ultrasound abnormalities of varying degrees: size change (3/9), echo enhancement (8/9) and cysts (3/9). Extrarenal phenotypes were present in 3 children. Genetic test showed that 6 patients had mutation of NPHP1 gene, 1 patient had mutation of WDR19 gene, 1 patient had mutation of NPHP3 gene and 1 patient had mutation of NPHP5 gene. Conclusions:Deletion mutation of NPHP1 gene is the most common, while NPHP3, NPHP5 and extremely rare WDR19 mutations have also been found in NPHP patients. The clinical manifestations of NPHP are not typical, so it is necessary to find a specific diagnosis method in the early.

Objective To investigate the clinical manifestations and genetic features of children with papillorenal syndrome caused by PAX2 gene mutation.Methods Clinical manifestations,imaging changes and sequencing data were collected and analyzed from a family with papillorenal syndrome who were diagnosed in Wuhan Children's Hospital in February 2018."PAX2","papillorenal syndrome" and "renal coloboma syndrome" were used as key words to search in China National Knowledge Infrastructure,Wangfang Data Knowledge Service Platform,PubMed and Human Gene Mutation Database up to April 2018.Results A ten years old girl was admitted due to "edema and urine output decreased for one week".Lab showed BUN 25.30 mmol/L,Scr 766.5 μmol/L,Urine protein 3.6 g/24 h.Imaging examination showed bilateral vesical and ureter reflux combined with left duplex kidney and duplication of ureter.Developmental dysplasia of the left hip was also found.The father of the patient had been diagnosed with chronic kidney disease for 10 years and on hemodialysis for 6 years.Next generation sequencing revealed that both the father and daughter carried a heterozygous nonsense mutation in the exon3 c.219C ＞ G(p.Y73X) of PAX2.No Chinese literature ever was reported about papillorenal syndrome.Ninety-four articles in English were retrieved and 177 patients with papillorenal syndrome were confirmed by gene analysis with a total of 92 PAX2 variants.Ten nonsense mutations had been reported.Developmental dysplasia of the hip (DDH) never be reported before.Conclusion Papillorenal syndrome caused by PAX2 mutation can mainly manifest as abnormal development of both kidney and optic nerve,which may be accompanied by other systemic abnormalities,it is rarely reported in China.DDH may be a new phenotype of papillorenal syndrome.
