Wilms' tumor is the most common kidney tumor in childhood.MicroRNAs (miRNAs) are about the size of 19-22 nucleotide sequences that exist widely in the non-coding RNA in eukaryotes,function primarily through combination with mRNA target base pairing causing target mRNA degradation or inhibition of translation,and then develop his inhibiting or promoting the role of tumor.Abnormal expressions of miRNAs can cause a lot of kidney diseases,such as chronic kidney disease,polycystic kidney disease,renal fibrosis and renal cancer.Wilms'tumor,abnormal expression of key genomes,such as miR-17-92,miR-185,miR-204,miR-48 anomalies and tumors are closely related.Paper of miRNAs in incidence of Wilms'tumor expression,and the possible role for future targeted gene targeted drug sites are reviewed.

Objective To investigate the monocyte chemoattractant protein (MCP1) gene expression of the bladder urothelial carcinoma and its correlation with the pathogenesis of the bladder urothelial carcinoma.Methods Thirty cases of patients with the bladder urothelial carcinoma, including 20 cases of male and 10cases of female, were taken the blood and bladder tissue.In control group, 30 cases of non-cancer patients,including 20 cases of male and 10 cases of female, were taken the blood samples.ELISA method was used to detected the concentration of plasma MCP1, immunohistochemical method to investigate the expression of MCP1 in the bladder urothelial carcinoma and adjacent tissues.Real-time quantitative RT-PCR was applied to detected the expression of MCP1. Data of the two groups were comparied and the relationship between the expression of MCP1 and the clinical characteristics of the bladder urothelial carcinoma was analyzed.Results MCP1 in group of patients with the bladder urothelial carcinoma was (193.4±105.7) pg/ml, and higher than that in non-tumor group (91.8±34.6) pg/ml (t = 8.37, P ＜0.001).MCP1 in invasive bladder cancer was (204.3±167.5) pg/ml and superficial bladder cancer was (130.6±69.2) pg/ml (t = 2.667, P = 0.013). By immunohistochemistry, the MCP-1 positive rate in the bladder urothelial carcinoma was 70.0 % (21/30), that in adjacent cancer tissue was 43.3 % (13/30) (χ2 = 4.9, P ＜0.05). The positive rate of MCP1 in invasive bladder cancer in tumor group was 80.0 % (8/10) and that in superficial bladder cancer was 65.0 %(13/20).At the same time, MCP- 1 positive intensity in the bladder urothelial carcinoma was significantly higher than that in adjacent tissues. The intensity in invasive bladder cancer was higher than that in superficial ones. Total RNA and mRNA levels of MCP-1 in the bladder urothelial carcinoma were statistically differences compared with that in adjacent tissues (χ2 = 10.08, P ＜0.05).Conclusion The upregulation of MCP1 gene expression is likely to play an important role in the incidence and metastasis of the bladder urothelial carcinoma.

Objective To investigate the clinical characteristics of hypertrophic cardiomyopathy (HCM) in the elderly. Methods The clinical characters of HCM in 70 elderly patients were retrospectively analysed. Results Among the 196 identified HCM patients, 70 were elders. Out of them, 7 patients(10.0%) were suspected as HCM according to the clinical symptoms, 29 patients (41.4%)were suspected as other cardiac diseases, 34 (48.3%) were diagnosed HCM due to other reasons. Among the 70 patients, 12 patients(17.1%) had history of cerebrovascular diseases, 54 (77.1%) manifested symptoms after 45 years of age and 4 (5.7%) showed no obvious symptoms. Among them, 18 patients were examined by UCG for two times and HCM was diagnosed at the second time. Conclusions HCM in the elderly is not an uncommon disease. The onset of cardiac symptoms is relatively late in the elderly HCM and frequently misdiagnosed; cerebrovascular diseases are commonly seen in elderly HCM patients.

Objective To evaluate magnetic resonance imaging (MRI) in the diagnosis of deep anorectal abscess. Methods Twenty-one patients who were suspected of having deep anorectal abscess were admitted to the Affiliated Hospital of Nanjing University of Chinese Medicine from January 2006 to December 2007, and their clinical data were retrospectively analyzed. Phased-array coil MRI was applied to all patients before the operation. We compared the efficacy of MRI and rectal digital examination in the classification of deep anorectal abscess and the diagnosis rate of internal opening according to the postoperative results. All data were analyzed using the chi-square test. Results Nineteen patients were diagnosed with deep anorectal abscess, one patient had presacral cyst combined with infection and one patient had perianal mucinous adenocarcinoma. A total of 25 lesions were identified, including 14 ischiorectal abscesses, five pelvirectal abscesses, and six high intersphincteric abscesses. Thirteen patients had single space abscesses and six had multiple space abscesses. There were no significant differences in the diagnosis rate between MRI (12/19) and rectal digital examination for internal opening (13/19) (χ2 =0. 116, P>0.05). The accuracy rate was significantly different between MRI (25/25) and rectal digital examination (16/25) in the classification of deep anorectal abscess (χ2 = 10.970, P <0.05). Operative exploration revealed that there were 13 patients with single space abscesses and six with multiple space abscesses. The accuracy rate was significantly different between MRI (19/19) and the rectal digital examination (13/19) for detecting multiple space abscesses (χ2 =7. 125, P <0. 05). Conclusions MRI with a phased-array coil can accurately detect the extent of deep anorectal abscess and its relationship with anorectal sphincters. MRI examination is helpful in excluding potential lesions in the anorectal region.

The bile was collected from fro patients with biliary infections, with the bacterium isolated to study the sensitivity of each kind of the bacterium to several antibiotics in common use. Except G- bacterium, we also found some kinds of G+ bacterium in infection bile. G- bacterium were not sensitive to Clindamycin, G+ bacterium were sensitive to Ciprofloxacin. Escherichia coli, Xanthomonas maltophilia, Enterobacter cloacae, Pseudomonas aeruginosa were sensitive to Ampicillin. G+ bacterium were not sensitive to Azactam. Enterococcus faecalis, Enterococcus faecium, Enterobacter cloacae were not sensitive to Ceftazidime. Enterococcus faecalis, Staphylococcus coagulase negative, Staphylococcus epidermidis, Pseudomonas aeruginosa were not sensitive to Ceftriaxone Sodium. We didn't found any bacterium resistance Imipenem. The possibility of the existence of G+ bacterium as well as drug resistance should be considered n patients with biliary infections. The value of susceptibility test should be respected to avoid drug abuse of antibiotics.

Objective To investigated the role of antithrombin Ⅲ (AT-Ⅲ) levels in the early diagnosis of disseminated intravascular coagulation (DIC) in patients with sepsis and the predictive effect of AT-Ⅲ on the development of DIC.Methods A retrospective study was conducted. Patients admitted to intensive care unit (ICU) of the First Affiliated Hospital of China Medical University from January to December in 2015 were enrolled. The patients were divided into sepsis group and non-sepsis group according to the diagnostic criteria of sepsis. In addition, sepsis patients were divided into 3 subgroups according to the international society on thrombosis and haemostasis (ISTH) scores on the first day: overt DIC (ISTH ≥ 5), non-overt DIC (ISTH 1-4) and none DIC group (ISTH = 0). Blood routine test, prothrombin time (PT), fibrinogen (Fib), D-dimer, fibrin degradation products (FDP), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores, sequential organ failure assessment (SOFA) scores and ISTH scores were recorded on the first ICU day. AT-Ⅲ was recorded during 7 days. The differences were compared among these 3 groups. Correlations of AT-Ⅲ with various parameters were calculated by using Pearson correlation analysis in sepsis group and overt DIC group. Receiver operating characteristic (ROC) curves for diagnosis of DIC with AT-Ⅲ, AT-Ⅲ+PT were drawn to evaluate the diagnostic efficiency. The AT-Ⅲ levels of DIC patients were compared between early-onset DIC and late-onset DIC during their ICU stay. The change of AT-Ⅲ levels with time and prognosis in patients with early-onset DIC was compared between groups.Results Totally 445 patients were recruited, with 138 patients in sepsis group, and 307 in non-sepsis group. There were 20 patents diagnosed with overt DIC on the first ICU day, 115 patients non-overt DIC and 3 patients of none DIC. Twenty-five sepsis patients were diagnosed overt DIC during the ICU days. AT-Ⅲ level in sepsis patients on the first ICU day were lower than that in non-sepsis patients [(55.29±13.92)% vs. (76.54±12.31)%,P < 0.01]. Patients with overt DIC had a lower AT-Ⅲ level than non-overt DIC or none DIC patients [(43.85±13.00)% vs. (56.95±13.03)%, (68.00±16.52)%, bothP < 0.05]. It was shown by Pearson correlation analysis that AT-Ⅲ level of sepsis patients on the first ICU day was negatively correlated to ISTH score and PT (r value were -0.467, -0.654, bothP < 0.01). AT-Ⅲ level of overt DIC patient on the first ICU day was negatively correlated with PT (r = -0.675,P = 0.001). It was shown by ROC curve that area under ROC curve (AUC) of AT-Ⅲ combined with PT for diagnosis overt DIC in sepsis patients was higher than that of AT-Ⅲ or PT alone (0.843 vs. 0.763, 0.834), the sensitivity 90.0%, specificity 73.7%. The cut-off value for overt DIC diagnosis in sepsis patients of AT-Ⅲ level alone was 48.5%, sensitivity was 78.0%, specificity was 70.0%. On the first ICU day, AT-Ⅲ level was risen when ISTH score improved in patients with sepsis. There was similar change of AT-Ⅲ level between patients with early-onset DIC and late-onset DIC. AT-Ⅲ level increased with DIC improvement.Conclusion AT-Ⅲ level can be used for diagnosing sepsis-associated overt DIC independently or with a combination of PT. When ISTH score improved, AT-Ⅲ level was risen in patients with sepsis associated DIC.

Objective To compare the diagnostic value of endoscopic ultrasonography (EUS) versus intraoperative cholangiography (IOC) for suspected common bile duct stones (CBDS).Methods 324 patients with suspected CBDS who were admitted to the Hepatobiliary Pancreatic Surgery Department of Shaoxing People's Hospital between June 2010 and June 2014 were retrospectively studied.Either EUS or IOC was used and the diagnostic value of these two imaging modalities was compared.Results The sensitivity, specificity, positive predictive value and negative predictive value of IOC in diagnosing suspected CBDS were 90.6％, 98.4％, 9.5％ and 97.7％ respectively.Its consistency rate was 96.9％.The sensitivity, specificity, positive predictive value and negative predictive value of EUS in diagnosing suspected CBDS were 97.1％, 100％, 100％ and 99.1％ respectively.Its consistency rate was 99.3％.Conclusions In diagnosing suspected CBDS, the sensitivity, specificity, positive predictive value and negative predictive value of EUS were significantly higher than IOC.When compared with IOC, EUS was more sensitive to detect occult CBDS and avoided unnecessary ERCP or bile duct exploration.Patients with negative EUS were less likely to have retained CBDS.

BACKGROUND:Old femoral neck fractures with senile osteoporosis have more surgical difficulties.There are a lot of intraoperative and postoperative complications and long-term effects are poor.OBJECTIVE:To explore the clinical outcomes of hip arthroplasty in patients with old femoral neck fractures with senile osteoporosis.METHODS:From October 2012 to July 2014,20 patients with old femoral neck fractures and senile osteoporosis were enroled in this study.Posterolateral approach was used to perform hip arthroplasty.Of them,14 patients received primary total hip arthroplasty with biological prosthesis,and 6 patients were subjected to semi-hip arthroplasty with straight shank cylindrical renovated biological prosthesis.RESULTS AND CONCLUSION: The patients were folowed up for 3 to 24 months.Harris score was apparently increased after arthroplasty in patients with old femoral neck fractures and senile osteoporosis compared with pre-arthroplasty.Postoperative radiographs revealed that femoral stem biological fixation was good.Bone fixation was visible in radiographs at 3 months after arthroplasty.These findings suggested that old femoral neck fractures and senile osteoporosis could be treated with hip arthroplasty.To select the type of prosthesis and surgical methods according to the femoral calcar-medulary cavity ratio in patients with old femoral neck fractures and senile osteoporosis can effectively restore the function of hip joint.

Objective To investigate the effect and recurrence of the esomeprazole combined with trimebutine on treatment for non-erosive reflux disease(NERD).Methods One hundred and twenty-five cases of patients with NERD were randomly divided into the treatment group (n =62) and the control group (n =63).Patients in treatment group were received the esomeprazole 20 mg,twice a day and trimebutine 0.2 g,3 times a day,in control group were received the esomeprazole 20 mg,twice a day and mosapride 5 mg,3 times a day.After 8 weeks treatment,6 months follow-up was conducted and the effects and recurrence were evaluated.Results The clinical curative rates at 4th and 8th weeks treatment in treatment group were 75.8％ (47/62) and 95.2％ (59/62),higher than that of control group (57.1％ (36/63),x2 =4.879,P =0.027 ; 84.1％ (53/63),x2 =4.083,P =0.043).The GERDQ curative rates at 4th and 8th weeks treatment in treatment group were 72.6％ (45/62),93.5％ (58/62) respectively,significantly higher than that of the control group (52.4％ (33/ 63),x2 =5.434,P =0.020 ; 79.4％ (50/63),x2 =5.350,P =0.021).The recurrence rates of 6 months followup were 77.4％ (48/62) in the treatment group and 81.0％ (51/63) in the control group,there was no significant difference between the two groups (P =0.627).Conclusion Esomeprazole combined with trimebutine is safe and effective treatment on non-erosive reflux disease,and the recurrence rates was lower than that in the control group.

As a kind of source wide,low inherent immnunogenicity multipotent stromal cells,mesenchymal stem cells (MSCs) have been used to cell-based therapeutic researches of immunodeficient deseases or other severe clinical disorders.Despite low levels of engraftment in the injured lung,numerous preclinical trials indicate that mesenchymal stem cells can promote damaged tissue repair constructed by secreting paracrine factors to regulate the host immunity,inhibit inflammation and restore epithelial integrity.Acute lung injury(ALI) is a serious organ dysfunction occurred earliest and the most commonly affected organ.Currently there is no effective medicine therapy and the mortality remains high.Researches demonstrate MSCs can reduce alveolar edema,improve lung function and reduce motality.So understanding of the mechanism will be conductive to the MSCs from experimental stage into clinical application.This issue will put a brief overview pointed on the mechanism of mesenchymal stem cells in repairing the injured lung.
