Results were showed that 918 bp nanog fragments were expressed in mouse ES cells mediated by lentiviral vector PLL-IRES-Nanog-Neo,mouse nanog-ES cells were taken on mass-like image and positve with alkaline phosphatase staining and Oct4 and SSEA1 immunocytochemistry under no LIF condition in the media. It is concluded that mouse ES cells Elevated nanog gene expression by mediation of lentiviral were constucted and cultured.

OBJECTIVERecent studies have shown that integrin linked kinase (ILK) plays an important role in the pathogenesis and development of some kidney diseases. This study aimed to investigate the relationship between ILK and renal glomerular damage in children with Henoch schonlein purpura nephritis (HSPN).

METHODSOne hundred and eighty eight HSPN children (aged 3 to 17 years) were assigned to five groups according to the classification of the International Study of Kidney Disease in Children (ISKDC): grade < or = IIa (n = 62), grade IIb (n = 42), grade IIIa (n = 29), grade IIIb (n = 40) and grade > or = IV (n = 15). Fifteen children with basement membrane nephropathy served as the control group. ILK expression on glomeruli was ascertained by immunohistochemical staining. The relationships of ILK expression on glomeruli with glomerular histopathologic lesions and urinary protein excretions were examined.

RESULTSThe positive areas of ILK expression on glomeruli in the control, grade < or = IIa, grade IIb, grade IIIa, grade IIIb and grade > or = IV groups were (3.35 + or - 1.01)%, (4.88 + or - 1.13)%, (9.64 + or - 1.36)%, (11.27 + or - 1.68)%, (17.42 + or -3.0)% and (20.62 + or - 2.32%), respectively. There were significant differences in the ILK expression between groups (p<0.01). ILK expression on glomeruli increased with increased urinary protein excretions. There were significant differences in the ILK expression in children with different urinary protein excretions (p<0.01).

CONCLUSIONSILK might be involved in the process of renal glomerular histopathologic damage and the production of proteinuria in children with HSPN.

Objective To investigate the nursing method to spine surgery inpatients suffering postoperative cognitive dysfunction. Methods Nineteen spine surgical patients who had postoperative cognitive dysfunction were closely observed , and special nursing measures such as cognitive behavioral intervention, save care, sleep care and comfort care were taken. Results Patients' mental symptoms lasting 3 ～ 10 days lessened gradually after receiving specific treatment and nursing. 15 Discharged Patients were followed up. Their cognitive dysfunction could improve gradually and could be recovered at last. Conclusions Postoperative cognitive dysfunction after Spine surgery can be found more easily in old patients. Careful observation and active nursing intervention can reduce the cognitive damage of POCD patients and promote their recovery effectively.

Objective To analyze the surveillance data on hemorrhagic fever with renal syndrome (HFRS) including the epidemiological characteristics and trend of the disease,in 2010.Methods Descriptive methods were conducted to analyze the surveillance data in 2010 which were collected from the internet-based National Notifiable Disease Reporting System and 40 HFRS sentinels in China.Results There were 9526 cases of HFRS reported in 2010 in the country with an annual morbidity of 0.71/105,which was higher than that reported in 2009.And the case fatality rate in 2010 was 1.24％.During the year 2010,most cases were reported in spring and autumn-winter season,with November as the peak month.The proportion of cases reported in autumn-winter season was higher than that in spring.The number of cases reported in males was higher than that in females among all the age groups,and similar pattern of mortality could be seen in most of the age groups.The percentage of cases over 60 years old had increased in recent years.Farmers were still under the highest risk.Density and the virus-carrying rate of animal hosts,as well as the infection rate were relatively stable and similar to the previous findings.As to the prevailing species,Apodemus agrarius and Rattus norvegicus were still the most common and leading animal hosts.However,the dominant species in sentinel of Yunnan were Rattus flavipectus and Eothenomys miletus respectively,and a new hantavirus called LUXV was found,namely Eothenomys miletus.Conclusion HFRS cases were widely distributed in most provinces of China,but cases mainly focus on certain areas and present the nature of aggregation.The risk of outbreak could not be ruled out for variety of factors.Population characteristics and seasonal fluctuation had been changing.

OBJECTIVETo investigate the distribution of congenital heart disease (CHD) aged 3 - 18 in several regions of Yunnan province.

METHODSCross-rectional studies were carried out among 48 638 children from Xishuangbanna, Dali, Baoshan Longling, Luxi Mangshi and Gejiu in Yunnan province with stratified, clustered sampling.

RESULTSThe overall morbidity of CHD was 5.08 per thousand with 5.09 per thousand in males and 5.07 per thousand in females. Morbidity rates in different regions were 2.75 per thousand in Xishuangbanna, 7.85 per thousand in Dali, 9.59 per thousand in Baoshan Long ling, 4.80 per thousand in Gejiu, 16.99 per thousand in Luxi Wuchalu. However, in the same area, rates were different among different residents:3.25 per thousand in Gejiu, and was 9.10 per thousand in Laochang stannum mine, 11.20 per thousand in Datunxuanchang; 5.74 per thousand at the city of Baoshan Longling, 11.35 per thousand at countryside; 4.90 per thousand at the city of Dali, 8.71 per thousand at countryside; 1.69 per thousand at the city of Xishuangbanna, 4.40 per thousand at country. Morbidity rates in different ethnic groups were as follows: 5.39 per thousand in Dai, 6.83 per thousand in Jinuo, 0 per thousand in Hani, 8.12 per thousand in Bai, 14.18 per thousand in Jingpo.

CONCLUSIONThere were significant regional and ethnic differences seen in Yunnan on the mobidity of CHD which was different from the domestic literature reported.

OBJECTIVETo study the expression of a novel marker, kidney-specific-protein (Ksp)-cadherin, in renal epithelial neoplasms and its clinicopathologic significance.

METHODSImmunohistochemical study (using EnVision method) for Ksp-cadherin, CD10, vimentin, epithelial membrane antigen and CK7 was carried out in normal human kidney samples, as well as in 166 cases of primary renal neoplasms (including 120 cases of clear cell renal cell carcinoma (RCC), 20 cases of papillary RCC (type I papillary RCC 15 cases and type II papillary RCC 5 cases), 18 cases of chromophobe RCC and 8 cases of oncocytoma).

RESULTSKsp-cadherin was expressed in distal convoluted tubules of normal kidney in a membranous pattern. It was also detected in 23% (27/120) of clear cell RCC, 20% (4/20) of papillary RCC, 100% (18/18) of chromophobe RCC and 75% (6/8) of oncocytoma. High expression of CD10 and vimentin was noted in clear cell RCC and papillary RCC. CD10 was also expressed in chromophobe RCC in cytoplasmic pattern, compared with membranous staining in the other tumors. CK7 expression was mainly seen in chromophobe RCC and papillary RCC, while epithelial membrane antigen was expressed in all variants of RCC. On the other hand, the expression of Ksp-cadherin in clear cell RCC correlated with tumor stage and grade.

CONCLUSIONSKsp-cadherin is expressed in normal distal convoluted tubules and the related neoplasms. It carries relatively high specificity and sensitivity in diagnosis of chromophobe RCC and oncocytoma. The expression of Ksp-cadherin also correlates with biologic behavior of clear cell RCC.

To evalue the coincidence and correlation between the four domestic quantity assay reagents and with ARCHITECTi2000 immunoassay system. 185 weak-reactive serum samples and standard materials of different concentrations were tested by four domestic quantity assay reagents for HBsAg test and ARCHITECTi2000 immunoassay system. The coincidence, the precision and the correlations between different systems were analyzed. The coincidence rates of the results of 0.05-1.00 IU/ml samples between the four domestic quantity assay reagents and ARCHITECTi2000 immunoassay system were 25.93%, 35.19%, 51.85% and 18.52% respectively, and for those results of more than 1.00 to 10.00 IU/ml samples the coincidence rates were 71.76%, 87.79%, 95.42% and 69.47% respectively. The samples of 0.05 to 0.80 IU/ml weak-reactive serum samples detected by the i2000 system were all negative detected by the four domestic systems. The coincidence rates of more than 7.93 IU/ml serum samples detected by i2000 system were 100% detected by the four domestic systems. The correlations of the four domestic quantity assays were around 0.8629 to 0.9265. The analysis sensitivity of the four domestic quantity assay reagents were below the i2000 system. The results of under 0.80 IU/ml samples detected by i2000 system were disaccord with the results detected by the four domestic systems, whereas for the sapmples over 7.93 IU/ml the results were consistent.

BACKGROUNDPeople with metabolic syndrome are at higher risk for developing coronary artery disease (CAD). The effect of the metabolic syndrome on outcomes in patients with preexisting CAD has not been well studied. This study was conducted to assess the prevalence, characteristics, in hospital and long term prognosis of CAD with metabolic syndrome and to determine the factors influencing the prognosis of the disease.

METHODSThe DESIRE registry contains data of 3696 patients with CAD between 2001 and 2004. Mean long term followup was (829 +/- 373) days. Diagnosis of metabolic syndrome was based on modified International Diabetes Federation (IDF) Worldwide Definition of the Metabolic Syndrome, using body mass index (BMI) instead of waist circumference.

RESULTSOf 2596 patients with complete records of height, weight, and so on, 1280 (49.3%) were identified with metabolic syndrome. The patients with metabolic syndrome had higher level of body mass index, systolic blood pressure, diastolic blood pressure, fasting glucose and disordered blood lipid (all P < 0.0001), with higher creatinine [(10.5 +/- 4.3) mg/L vs (9.9 +/- 2.9) mg/L, P < 0.0001] and the number of white blood cells [(7.49 +/- 2.86) x 10(9)/L vs (7.19 +/- 2.62) x 10(9)/L, P = 0.008) compared with those without metabolic syndrome. The patients with metabolic syndrome showed severer coronary angiographic alterations (left main artery and/or > or = 2-vessel) (73.6% vs 69.6%, P = 0.031). There were no significant differences of major adverse cardiac and cerebral events (MACCE) or mortality in hospital between the two groups. During followup, the ratio of MACCE in CAD with metabolic syndrome patients increased significantly (11.8% vs 10.0%, P = 0.044). Fasting blood glucose (> or = 1000 mg/L) and triglyceride (TG, > or = 1500 mg/L) were responsible for most of the increased risk associated with the metabolic syndrome (adjusted OR 1.465, 95% CI 1.037 - 1.874, P = 0.032; OR 1.378, 95% CI 1.014 - 1.768, P = 0.044).

CONCLUSIONSThe prevalence of metabolic syndrome was very high in CAD patients. The metabolic syndrome confers a higher risk of long term MACCE in patients with CAD, and dysglycaemia and hypertriglycaemia appear to be responsible for most of the associated risk.
