Objective To analyze the clinical characteristics,prognosis and the risk factors in 48 children with lupus nephritis combined with renal insufficiency.Methods The clinical data from 48 pediatric lupus nephritis with renal insufficiency from January 2000 to January 2013 were retrospectively analyzed.Results Forty-eight cases showed renal insufficiency among 168 children with lupus nephritis,and the incidence rate was 28.6％.The age ranged from 5.8 to 16.2 years.The male to female ratio was 1.0 ∶ 2.2.Among 48 children,43 cases had hematuria,41 cases had heavy proteinuria,25 cases had anaemia and 23 cases had persistent hypertension.Totally 20 cases underwent renal biopsy,and among them,15 cases(75.0％) were diagnosed as diffuse proliferative lupus nephritis(class Ⅳ).The histological activity index was ≥7 in 13 cases and the histological chronicity index was ≥4 in 3 cases.Corticosteroid and/or cytotoxic drugs were used in all of 48 cases.Thirty-five cases had normal urine and renal function,5 cases had stable renal function with persistent proteinuria,4 cases developed into chronic renal failure and 4 cases died.Persistent hypertension (x2 =4.274,P =0.039),the time of starting therapy (x2 =28.830,P =0.000),and histologic chronicity index(P =0.008 8 by Fisher's exact probability test)were the prognostic factors.Conclusions Among pediatric lupus nephritis with renal insufficiency,class Ⅳ (diffuse proliferative lupus nephritis) is the most frequent finding.Persistent hypertension,the time of starting therapy,and histologic chronicity index are the prognostic factors.The outcomes of lupus nephritis with insufficiency can be improved by adequate and appropriate treatment.

Objective To explore the clinical features of invasive fungal infection in 27 children treated at nephrology department between 1999 and 2014.Methods Twenty-seven cases of invasive fungal infection at nephrology department were analyzed retrospectively.Results Candida urinary infection was found in 9 cases,pneumocystis carinii pneumonia were found in 8 cases,invasive pulmonary aspergillosis and urinary aspergillosis found in 4 cases and 1 case respectively,cryptococcus neoformans meningitis and pulmonary candidiasis found respectively in 2 cases,and pulmonary filamentous fungal disease was found in 1 case.These 27 cases showed different features of illness:10 primary nephrotic syndrome,7 secondary nephrotic syndrome,6 malformation of urinary development and 4 preterm birth ＜ 32 weeks gestational age with low birth weight.All of the cases had the history of taking antibiotics.Seventeen cases of them had used corticosteroid and cytotoxic drugs in a long-term.Sixteen cases had experienced invasive procedures.All children had fever in varying degrees,14 cases showed gasp,7 cases had progressive hypoxia and respiratory failure,and 5 cases developed into multiple organs failure.Chest computed tomographic (CT) imaging data showed diffuse ground-glass opacity with mosaic sign of pneumocystis carinii pneumonia(8 cases).The features of pulmonary aspergillosis included multiple nodules and cavity in bilateral lungs (4 cases).The radiologic findings showed patching lesions with indistinct edge and uncertained density of bilateral middle-lower lung fields with pulmonary candidiasis (2 cases).Full dose of antifungal drug was given to 23 cases of them,16 cases recovered completely,3 got better,4 cases died.Four cases gave up full dose antifungal therapy.Conclusions Long-term use of corticosteroid and cytotoxic drugs,use of broad-spectrum antibiotics,invasive therapies,such as indwelling centralvenous catheters,endotracheal intubation with mechanical ventilation,and preterm birth with low birth weight were risk factors in predicting invasive fungal infection.Chest CT findings were different among these cases.Even though not specific,the relatively differences were helpful to the differential diagnosis of these diseases.

Objective To investigate the risk factors with lymph node metastatic recurrence in patients with N0 esophageal cancer after Ivor-Lewis Esophagectomy. Methods The subjects were 82 patients with pN0 esophageal cancer who underwent Ivor-Lewis esophagectomy from January 2001 to January 2005. By using RT-PCR, VEGF-C mRNA was detected in tumor issues, and Mucin l( MUC1 )mRNA was detected in lymph nodes. The Kaplan-Meier method was used to calculate the survival rate and lymph nodal metastatic rate. Log-rank test was performed to compare the recurrence rate, and Cox regression multivariate analysis was performed to determine independent prognostic factors. Results VEGF-C mRNA was identified in 42 patients (51.22%), and MUC1 mRNA was identified in 23 patients(28.05% )from at least 1 lymph node station . The diagnosis of lymph node micrometastasis (LNMM) was based on the detection of MUC1 mRNA. The first recurrence exhibiting lymph node metastasis was recognized in 37 patients (45.1%) at the first 3 years after operation and this was significantly associated with T status ( P ＜ 0. 05 ). Lymph node metastatic rate for patients with VEGF-C mRNA expression in tumor issues was significantly higher than that for patients without VEGF-C mRNA expression( P ＜0. 01 ). And lymph node metastatic rate for patients with LNMM was significantly higher than that for patients without LNMM ( P ＜0. 01 ). The results of multivariate analysis confirmed that T status, VEGF-C mRNA expression in tumor issues and LNMM were independent relevant factors. Conclusion Status,VEGF-C mRNA expression in tumor issues and LNMM in patients with N0 esophageal cancer were independent risk factors for 3-year lymph node metastatic recurrence after Ivor-Lewis Esophagectomy.

Objective To investigate the expression of chemokine receptor CCR7 and its correlation with lymph node metastasis and prognosis in esophageal cancer after esophagectomy. Methods One hundred and eighty-four patients with middle third squamous cell carcinoma of the esophagus were enrolled in this study. All patients underwent operation in Provincial Hospital Affiliated to Shandong University between June, 2003 and June, 2005. The expression of CCR7 was detected by immunohistochemistry. All statistic analyses were performed with SPSS 13.0 statistical software. According to the clinico-patho-logic factors, the difference of CCR7 expression was compared by x2 test. Kaplan-meier method was performed to calculate the survival rate, Cox regression multivariate analysis was performed to determine independent prognostic factors. Results The expression rate of CCR7 in stage Ⅰ , stage Ⅱ and stage Ⅲ patients was 25.0 % , 70.3% and 85.5% , respectively. The difference of CCR7 expression between stage Ⅱ and stageⅢ was statistically significant (x2 =5.0, P =0.02). The CCR7 expression rate in T1, T2 and T3 patients was 33.3% , 64.9% and 80.9% , respectively. The difference of CCR7 expression between T2and T3 was statistically significant (x2 =5.4, P =0.01). The level of expression of CCR7 in patients with lymph node metastasis was significantly higher than those without metastasis (x2 =10.8, P = 0.00). The 5-year survival rate instage Ⅰ , stage Ⅱand stage Ⅲ patients was 100.0% , 38. 3% and 22.4% , respectively. The 5-year survival rate in patients with CCR7 overexpression was significantly lower than those without CCR7 overexpression (x2 = 23.7, P = 0.00). The 5-year survival rate in T2, T3, NO and N1 patients with CCR7 overexpression was significantly lower than those without CCR7 overexpression The result of Cox analysis demonstrated that T , N and CCR7 overexpression were independent prognostic factors. Conclusion CCR7 expression was detected in esophageal squamous cell carcinoma and was found to be significantly associated with T stage,N stage and lymph node metastasis. The patients with CCR7 expression was significantly lower the 5-year survival rate than without CCR7 expression. T stage, lymph node metastasis and CCR7 expression were independent prognostic factors.

Objective To investigate the expression of MTA1 protein and its relationship to the prognosis in esophageal cancer after esophagectomy. Methods One hundred and sixty-five patients with middle third squamous cell carcinoma of the esophagus were enrolled in this study. All patients underwent operation in Provincial Hospital Affiliated to Shandong University between January 2002 and January 2004. The expression of MTA1 protein was detected by immunohistochemistry. All statistic analyses were performed with SPSS 10.0 statistical software. According to the clinicopathologic factors, the difference of MTA1 protein expression was compared by x2 test. Kaplan-meier method was performed to calculate the survival rate, Cox regression multivariate analysis was performed to determine independent prognostic factors. Results The 5-year survival rate in Ⅰ stage,Ⅱ stage and Ⅲstage was separately 100.0% 、38.3% and 22.4%, and the MTA1 protein expression rate in Ⅰ stage, Ⅱ stage and Ⅲ stage was separately 25.0% 、30.9% and 57.9%, the difference of MTA1 protein expression between Ⅱ stage and Ⅲ stage was statistically significant ( x2 = 11.6, P = 0. 00). The MTA1 protein expression rate in T1 stage, T2 stage and T3 stage was separately 42.9% 、13.3% and 50%. MTA1 protein expression rate in T2 stage patients and T3 stage patients was separately 13.3% and 50%, the difference of MTA1 protein expression between them was statistically significant (x2 = 13.2, P =0.00). The positive expression of MTA1 protein in patients with lymph node metastasis was significantly higher than those without metastasis ( x2 = 8.2, P = 0.04). The 5-year survival rate in patients with MTA1 protein positive expression was significantly lower than those without MTA1 protein positive expression (P =0.00 ), and the 5-year survival rate in T3 stage patients with MTA1 protein positive expression was significantly lower than those without MTA1 protein positive expression ( P =0.01 ), and the 5-year survival rate in N0 stage patients with MTA1 protein positive expression was significantly lower than those without MTA1 protein positive expression (P = 0.03 ), and the 5-year survival rate in N1 stage patients with MTA1 protein positive expression was significantly lower than those without MTA1 protein positive expression ( P =0.04). However, the 5-year survival rate in T2 stage patients with MTA1 protein positive expression was not significantly lower than those without MTA1 protein positive expression (P =0.20). The result of Cox analysis demonstrated that N stage and MTA1 protein positive expression were independent prognostic factors. Conclusion MTA1 protein overexpression was detected in esophageal squamous cell carcinoma and was found to be significantly associated with T stage and lymph node metastasis. The patients with MTA1 protein overexpression was significantly lower the 5-year survival rate than without MTA1 protein expression. Lymph node metastasis and MTA1 protein overexpression were independent prognostic factors.

Objective: To explore the effect of radiotherapy on preventing the recurrence of lymph node metastasis of esophageal cancer after Ivor-Lewis esophagectomy. Methods: Three hundred and sixty-six pa-tients with middle third squamous cell carcinoma of the esophagus were enrolled in this study. All patients un-derwent Ivor-Lewis esophagectomy with two-field lymph node dissection in our hospital between June 1999 and June 2004. All statistical analyses were performed with SPSS 13.0 statistical software. Kaplan-Meier method was performed to calculate the relapse rate. Log-rank test was performed to compare the relapse rate. Cox regression analysis was performed to identify independent prognostic factors for postoperative lymph node metastasis. Results: Of the 366 cases, lymph node metastasis was found in 105 patients (28.5%)within 3 years after surgery, occupying 52.2% (105/201) of total recurrence. Of the 181 patients treated with postoperative radiotherapy, lymph node metastasis was found in 37 patients. The rate of lymph node metasta-sis was 20.4%, significantly lower than that in patients treated with chemotherapy alone and those without sys-temic adjuvant therapy (P<0.05). Chemotherapy was administered in 103 cases and lymph node metastasis was found in 33 patients. The rate of lymph node metastasis was 32.0%, lower than that in patients without systemic adjuvant therapy, but without statistical significance (P=0.17). The results of Cox analysis demon-strated that T stage, lymph node metastasis and postoperative adjuvant radiotherapy were independent prog-nostic factors. Conclusion: Ivor-Lewis esophagectomy for the middle third thoracic esophageal cancer was a safe surgical procedure. Postoperative radiotherapy is helpful for the control of local recurrence. T stage,lymph node metastasis and postoperative adjuvant radiotherapy are independent prognostic factors. Radio-therapy is helpful for preventing the recurrence of lymph node metastasis of esophageal cancer after Ivor-Lew-is esophagectomy.
