Objective To observe the difference of caveolin-3(CAV3) gene polymorphism between normal people and diabetic patients in Chinese Han population. Methods Exon gene polymorphism in 50 normal people and 50 T2DM patients were detected by PCR-SSCP. Results The cumulative incidence rate of electrophoretic variation in T2DM patients was 48%, while cumulative incidence rate of normal people was 7%(P<0.001). It was proved that in the variant bands, there were base variant. Conclusions The variant base number of CAV3 gene in human T2DM samples are significantly more than the normal which can be preliminary detected by PCR-SSCP. It indicates that CAV3 gene polymorphism may be one of the genetic backgrounds for the occurence of Chinese T2DM.

A total of 32 pieces of evidence were summarized from three aspects, consisting of nutritional risk screening and assessment, nutritional education or counseling, and nutritional intervention.Conclusions:This study summarizes the best evidence for nutritional management in elderly cancer patients. It is recommended that medical and nursing staff apply evidence based on clinical situations and patient preferences.

Objective:To discuss the diagnosis and treatment 0f WAGR syndrome.Methods:The clinical data of 10 cases of WAGR syndrome children admitted to our hospital from January 2008 to November 2019 were respectively analyzed including the clinical features, diagnosis, and surgical treatments. There were 6 males and 4 females, aged from 13 to 36 months, with an average of 23.6 months. 9 cases were diagnosed as iris absence due to ocular abnormalities in infancy, and 1 case was diagnosed as iris absence due to ocular abnormalities by physical examination because of renal mass. There were 2 boys with cryptorchidism, and 2 boys with hypospadias, 1 of which did not received operation because of mild hypospadias, and another undergoing surgery. There were no abnormality of genitourinary system in the remaining 5 cases. There were 7 cases of unilateral nephroblastoma, with 1 case at the left and 6 cases at the right, and there were 3 cases of bilateral nephroblastoma. Abdominal doppler ultrasound and enhanced abdominal CT were performed for all patients. Abdominal doppler ultrasound indicated solid mass in renal parenchyma or non-uniform echo zone. Abdominal enhanced CT indicated renal tumor with diameter of 1.8 cm-12.7 cm and locally non-uniform enhanced echo. Among the 7 cases of unilateral nephroblastoma, 4 underwent nephrectomy, 1 underwent tumor enucleation, and 2 underwent tumor enucleation for unilateral tumor complicated with nephrogenic rests. There were 3 cases of bilateral nephroblastoma, 2 cases undergoing unilateral tumor enucleation firstly and contralateral tumor enucleation following chemotherapy. One case underwent unilateral tumor nephrectomy followed by contralateral tumor enucleation. One case of unilateral nephrogenic rests did not undergo renal tumor surgery. Preoperative chemotherapy was performed in 7 patients, including 3 bilateral nephroblastoma, 1 unilateral nephroblastoma combined with contralateral nephroblastoma, and 3 unilateral tumors larger enough to pass the midline. The chemotherapy regimen was VCR+ ACTD in 5 cases, VCR+ ACTD+ CTX+ DOX/CDDP+ VP16 and VCR+ CTX+ DOX in another 2 cases respectively.Results:All 10 cases were diagnosed as nephroblastoma. There were 3 patients without preoperative chemotherapy which belongs to COG stageⅠ(1 case) and STAGEⅢ(2 cases); Preoperative chemotherapy was performed in 2 patients with SIOP stage Ⅱ, 2 patients with SIOP stage Ⅲ, and 3 patients with SIOP stageⅤ. Nine children received regular chemotherapy after surgery, among which 1 child in stage Ⅰ received DD4A chemotherapy regimens, 2 children in stage Ⅱ received DD4A and EE4A regimen respectively, and 3 of the 4 children in stage Ⅲ received regular chemotherapy after surgery, including EE4A(1 case)and DD4A(2 cases). EE4A(1 case)and DD4A(2 cases) chemotherapy were performed in 3 patients with stage Ⅴ according to their unilateral tumor stage. Ten cases were followed up, with 9 of the 10 cases having no tumor recurrence or metastasis, and death in 1 case. At present, abdominal doppler ultrasound of 1 child with nephrogenic rests showed no obvious progress. The renal function of 9 children was not significantly abnormal during the regular follow-up. The results of intelligence screening showed that 6 of the 10 patients were significantly behind their peers, and 4 had no obvious abnormality compared with their peers. Gene tests were performed 3 times after surgery, and the results showed the deletion of 11p13 and adjacent distal genes.Conclusions:WAGR syndrome is rare in clinical practice, and renal ultrasound should be monitored after diagnosis to detect renal tumors in early stage. For bilateral cases, renal function should be preserved as long as possible in order to reduce the probability of renal failure. Long-term follow-up of nephroblastoma with this syndrome is particularly important.

OBJECTIVES: The aim of this study was to evaluate the disease burden of prostate cancer (PC) and assess key influencing factors associated with the disease expenditures of PC in the United States. METHODS: The total deaths, incidence, prevalence, and disability-adjusted life-years of PC were obtained from the Global Burden of Disease Study 2019. The Medical Expenditure Panel Survey was used to estimate healthcare expenditures and productivity loss and to investigate patterns of payment and use of healthcare resources in the United States. A multivariable logistic regression model was conducted to identify key factors influencing expenditures. RESULTS: For patients aged 50 and older, the burden for all age groups showed a modest increase over the 6-year period. Annual medical expenditures were estimated to range from US$24.8 billion to US$39.2 billion from 2014 to 2019. The annual loss in productivity for patients was approximately US$1,200. The top 3 major components of medical costs were hospital inpatient stays, prescription medicines, and office-based visits. Medicare was the largest source of payments for survivors. In terms of drug consumption, genitourinary tract agents (57.0%) and antineoplastics (18.6%) were the main therapeutic drugs. High medical expenditures were positively associated with age (p=0.005), having private health insurance (p=0.016), more comorbidities, not currently smoking (p=0.001), and patient self-perception of fair/poor health status (p<0.001). CONCLUSIONS From 2014 to 2019, the national real-world data of PC revealed that the disease burden in the United States continued to increase, which was partly related to patient characteristics.

Objective To discuss the diagnosis and treatment of unilateral ectopic ureter in children.Methods The clinical data of 41 cases of ureteral ectopic children admitted to our hospital from January 2014 to June 2018 were retrospectively analyzed including the clinical features,diagnosis,surgical treatments.There were 4 males and 37 females patients,aged from 0.4 to 12.7 years,with an average of 3.5 years old.Urinary incontinence was the main manifestation in 35 cases,including 14 cases with urinary tract infection.Preoperative ultrasonography and IVP examination were performed in all the 41 children.The dynamic radionuclide renal imaging was performed in the children who showed no renal inhencement with IVP.There were 27 cases of ipsilateral renal duplication and 9 cases of ipsilateral renal dysplasia.Ectopic fusion of kidney with ipsilateral ectopic ureter has one case on each side,and bilateral renal duplication with ectopic fusion of kidney with left ureteral ectopic in 1 case.The ipsilateral kidneys were normal in 2 cases.There were 27 cases with renal duplication,24 cases with upper renal dysplasia due to upper heminephrectomy,3 cases with well upper renal function,2 cases with lower superior ureteral pelvis anastomosis,and 1 case with ureterocystostomy.Laparoscopic dysplasia nephrectomy was performed on 9 patients with renal dysplasia,and nephrectomy was performed on 3 patients with renal dysplasia with ectopic renal fusion.Ureterocystostomy was performed in 2 cases with normal kidney.Results All 41 patients were followed up for 4-57 months,with an average of 25.3 months.Among the 35 children with urinary incontinence before the operation,33 cases had complete disappearance of urinary incontinence symptoms,and 2 cases had urgent urinary incontinence after the operation,presenting as frequent and small amount of urine discharge,with a strong sense of urination urgency.The micturition interval was shortened,ranging from 30 to 40min in the daytime,and 2 to 3 hours at night.The parents of the children were required to remind them to micturate regularly.Of the 41 cases,3 developed urinary tract infection 6-10 months after operation,and cured by antibiotics without recurrence.Conclusions Ectopic ureter is relatively rare,but urinary incontinence is the most common clinical manifestation.Ultrasound examination could be the preferred examination method.IVP further identified the patients with ectopic ureter who had kidney combined with malformation and renal function.The surgical treatments are mainly based on the corresponding renal function,and the prognosis is good.

To analyze the clinical outcomes of emergency percutaneous intervention in acute myocardial infarction (AMI) during hospital, and to find the relevant risk factors for the prognosis and cardiac events. 
 Methods: We retrospective analyzed the patient with acute ST segment elevation myocardial infarction, who was successfully performed emergency percutaneous coronary intervention (PCI) in the Cardiac Cath Lab of the Second Xiangya Hospital from January 2010 to December 2014. According to situation for cardiovascular events, patients were divided into 2 groups. The clinical factors were compared between the 2 groups.
 Results: The incidence of adverse event was 22% (67/304). By using t test and χ2 analysis, we found that Cr, NT-proBNP, HCT, WBC, age>75, Killip grade≥2, TIMI flow after PCI≤2, arrhythmia, multi-vessel lesion, ST-segment resolution≥50%, long D2B time are statistically different between the 2 groups. Logistic analysis revealed that HCT, NT-proBNP, Killip grade≥2, TIMI flow after PCI≤2, ST-segment resolution≥50%, long D2B time were important predictors for cardiac events in-hospital.
 Conclusion: HCT, NT-proBNP, Killip grade≥2, TIMI flow after PCI≤2, ST-segment resolution≥50%, long D2B time are important predictors for cardiac events in-hospital. The prognosis for AMI patient after emergency PCI could be improved and the incidence of cardiac event in hospital could be reduced if the high risk factors can be properly handled.
