Objective To investigate the prognostic value of serum P-cadherin( P-cad)level in patients with non-small cell lung cancer(NSCLC). Methods A total of 80 patients with NSCLC in Hanzhong 3201 Hospital of Shaanxi Province from January 2012 to December 2013 were selected as study subjects. The relationships between serum P-cad level and clinicopathological characteristics were analyzed. The Cox regres-sion analysis was used to analyze the risk factors affecting prognosis of NSCLC patients. The survival curve was drawn by Kaplan-Meier method and the difference test was carried out by log-rank method. Results There were significant differences in lymph node metastasis(χ2 = 14. 31,P < 0. 001),vascular invasion(χ2 = 5. 56, P = 0. 018)among NSCLC patients with different levels of serum P-cad. Multivariate Cox regression analysis showed that lymph node metastasis(HR = 0. 856,95％ CI:0. 702-0. 955,P = 0. 012),TNM stage(ⅢA HR =1. 315,95％ CI:1. 058-1. 991,P = 0. 024;ⅢB HR = 1. 448,95％ CI:1. 124-2. 215,P = 0. 011;Ⅳ HR =1. 569,95％ CI:1. 182-2. 441,P < 0. 001)and high level of serum P-cad(HR = 1. 815,95％ CI:1. 224-3. 562,P < 0. 001)were risk factors for progression-free survival in NSCLC patients,and lymph node metasta-sis(HR = 0. 755,95％ CI:0. 652-0. 915,P = 0. 022),poor differentiation(HR = 1. 622,95％ CI:1. 112-2. 015,P < 0. 001),TNM stage(ⅢA HR = 1. 335,95％ CI:1. 064-2. 014,P = 0. 011;ⅢB HR = 1. 489, 95％ CI:1. 129-2. 297,P < 0. 001;Ⅳ HR = 1. 622,95％ CI:1. 192-2. 501,P < 0. 001)and high level of serum P-cad(HR = 1. 677,95％ CI:1. 193-2. 668,P < 0. 001)were risk factors for overall survival of NSCLC patients. The results of Kaplan-Meier survival curve showed that the overall survival and progression-free survival of patients with high level of serum P-cad were shorter than those of patients with low level of serum P-cad(χ2 = 5. 18,P = 0. 015;χ2 = 5. 48,P = 0. 011). Conclusion High level of serum P-cad is closely related to poor prognosis in NSCLC patients.

Objective To investingate the effect of SGK1 expression level on the prognosis of patients with NSCLC,and provide new biological predictors for the prognosis assessment of patients with NSCLS.Methods One hundred and twenty patients with NSCLC received radical resection in Hanzhong 3201 hospital from Jan 2011 to Dec 2013 were selected.There were 75 males and 45 females,age (63.15 ± 16.44) years,age range 45-80 years.According to the results of immunohistochemical staining,the SGK1 cut-off value determined by the integral was determined,and NSCLC patients were divided into SGK1 high expression group (n =70) and SGK1 low expression group(n =50).The relationship between the expression of SGK1 and clinicopathological features (age,sex,smoking history,alcoholism history,BMI,tissue type,tumor diameter,T stage,N stage,TNM stage,differentiation degree) in NSCLC were analyzed,and the overall survival rate in NSCLC were also analyzed.Followup was carried out by telephone or patient admission.The follow-up period was up to June 1,2018.Chest X-ray and ultrasonography were reviewed every 3 to 6 months after operation,and enhanced CT or MRI were performed if the results were abnormal.The measurement data conforming to normal distribution were expressed by t test and showed by (Mean ± SD);the counting data were tested by x2 test;the 5-year overall survival rate was used as the endpoint event for univariate analysis,and the significant variables for univariate analysis were analyzed by COX risk ratio model for multivariate analysis.The cumulative survival curve was drawn by Kaplan-Meier method,and the difference was tested by Log-rank method.Results The expression level of SGK1 in tissues was not related to age,sex,smoking history,alcoholism,BMI,tissue type and tumor diameter (P ＞ 0.05),but it was related to T stage,N stage,TNM stage and differentiation degree (P ＜ 0.05).The univariate and multivariate COX risk ratio model showed that TNM stage and SGK1 expression were independent factors affecting the 5-year overall survival rate of NSCLC patients (P ＜ 0.05).The results of Kaplan-Meier survival curve showed that the 5-year overall survival rate in NSCLC with low expression of SGK1 was significantly higher than that in NSCLC with high expression of SGK1 (P ＜ 0.05).Conclusions The expression of SGK1 in tissues is closely related to the prognosis of patients with NSCLC.The high expression of SGK1 in tissues is not conducive to the prognosis of patients with NSCLC.

A recurrent misdiagnosed case of congenital left renal arteriovenous fistula (RAVF) with multiple left renal arteries and scoliosis was reported. The patient was admitted to hospital on 29 August 2020 due to repeated hematuria for one year. No abnormality was found in two flexible ureteroscope examinations, imaging and laboratory examinations after admission. It was found that the structure of blood vessels in the inferior pole of renal sinus was disordered, and the blood vessels were tortuous and clustered through careful reading of CT enhancement films. The dilated tortuous blood vessels were also seen around the renal pelvis, and hematuria was considered to be caused by renal vascular malformation. In order to confirm the etiology, digital subtraction angiography (DSA) of renal artery was performed. DSA showed a congenital left renal RAVF with three renal arteries, and the arteriovenous fistula of renal arteries was embolized. For patients presenting with severe gross hematuria, if tumor, stone, tuberculosis, or coagulation abnormalities were excluded by conventional imaging and/or laboratory examination the possibility of congenital renal vascular malformation should be suspected, and DSA examination should be performed. Endovascular embolization is an effective treatment for congenital RAVF.

Solitary kidney, renal duplication and malrotation are rare congenital renal malformations in urology department, and probably contributed to some complications such as obstruction, hydronephrosis, infection, stones. In this case report, we firstly presented a male patient with rarely multiple renal malformations, including solitary kidney, renal duplication, misaligned malrotation of upper and lower moieties, and accompanied by complete staghorn stones and hydronephrosis, who was treated with open pyelolithotomy under general anesthesia. After the operation, obstruction, hydronephrosis, and infection were relieved.

Objective:To study the clinical characteristics of neonatal onset of diabetes mellitus.Methods:Neonatal onset diabetes mellitus infants admitted to Children's Hospital of Fudan University from January 2003 to December 2020 were selected for retrospective analysis. All clinical characteristics including the basic conditions, family history, clinical manifestations, laboratory examination, diagnosis and treatment were recorded and analyzed.Results:There were 21 cases of diabetes mellitus diagnosed during neonatal period, including 13 males and 8 females. There were 16 term infants and 5 premature infants with gestational age between 34 weeks and 40 weeks. The birth weight ranged from 1 420 g to 3 450 g, including 14 low birth weight infants, 2 very low birth weight infants and 13 small for gestational age infants. Four infants had family history of diabetes. All diabetic infants with onset time within 28 days after birth included 10 cases within 10 days, 4 cases between 11 days and 20 days, 7 cases between 21 days and 28 days. Hyperglycemia was the main feature of 21 infants, and their blood glucose was ≥11.1 mmol/L for many times, with a maximum of 41.98 mmol/L. Only 2 cases had ketoacidosis and 8 cases were complicated with infections. Genetic testing was performed in 6 neonates,2 cases of ABCC8 gene pathogenic variant, 1 case of KCNJ11 and 1 case of INS pathogenic variant, and 2 cases of negative results. Insulin was mainly used in the initial stage of treatment, and then orally glibenclamide was taken in 9 infants. After treatment, 15 patients had stable blood glucose and were discharged with medication. 5 infants were withdrawn the treatment and discharged, and 1 infant combined with other serious illness died after giving up the treatment by the parents.Conclusions:When diabetes is diagnosed during the neonatal period, it is helpful to choose the appropriate treatment and get good results.

Objective: To investigate the role and mechanism of Krüppel-like factor 4 (KLF4) in regulating epithelial-mesenchymal transition (EMT) and migration of bladder cancer cells. Methods: Bladder cancer 5637 and T24 cell lines that stably over-expressing KLF4 (LV-KLF4, experiment group) were constructed, and the negative control group (LV-NC) was also established; the mRNA and protein expressions of KLF4 were verified by qPCR and WB, respectively. Transwell chamber assay was used to detect the migration ability of cells in LV-KLF4 and LV-NC groups. WB was performed to detect the expression levels of EMT-related markers (E-cadherin, N-cadherin, Vimentin) and Wnt signaling pathway-related proteins. Immunofluorescence technique was used to detect the distribution of β-catenin in cells after over-expression of KLF4. Results: The 5637 and T24 cell lines over-expressing KLF4 gene were successfully constructed. Compared with the LV-NC group, the mRNA and protein expressions of KLF4 increased in LV-KLF4 groups (all P<0.01); the expression of E-cadherin increased (P<0.01), while the expressions of N-cadherin, vimentin, and the expression levels of total β -catenin, nuclear β -catenin, MMP 9 and c-Myc decreased (all P<0.01); moreover, the migration ability of cells decreased significantly (P<0.01); the fluorescence expression of β-catenin in cells also decreased significantly in LV-KLF4 group as compared to LV-NC group. Conclusion: Over-expression of KLF4 gene in bladder cancer cells may inhibit EMT process by regulating Wnt/β-catenin signaling pathway, and further inhibit the migration of bladder cancer 5637 and T24 cells.
