Objective To identify the risk factors for progression of advanced chronic kidney disease(CKD) patients who were cared by nephrologists in a specific CKD outpatient management clinic.Methods A prospective monocentric cohort study was performed.CKD patients of stage 3, 4 and 5 without renal replacement treatment were followed up regularly by nephrologists in this specific CKD management clinic.Patients with established atherosclerotic renal artery stenosis(ARAS) and chronic tubulointerstitial nephritis, and those who had not been followed-up for at least 12 months before Jun.30, 2010 were excluded.Clinical and laboratory data including blood pressure (BP), proteinuria, hemoglobulin (Hb), calcium phosphate product (Ca×P) and serum creatinine were consecutively collected.The treatment regimen was also recorded.Estimated glomerular filtration rate(eGFR) was calculated with the formula modified for Chinese to evaluate the change of renal function.The progression of kidney disease was defined as initiation of renal replacement therapy, the annual decrease of eGFR＞4 ml·min-1·(1.73 m2)-1, and/or death associated with renal disease.Results A total of 138 patients were enrolled in the final analysis with 84 patients of CKD stage 3, 36 of CKD stage 4 and 18 of CKD stage 5, respectively.At the time of enrollment, patients had an average age of (56.5:±:16.7) years old with an average eGFR of (32.3±13.4) ml·min-1·(1.73 m2)-1.During a mean follow-up interval of (27.1±12.1) months, the patients were well-controlled with an average blood pressure of (126.5±12.4)/(76.4±7.9) mm Hg in 50.7％(70/138), less than or equal to 130/80 mm Hg, an average Hb of(123.8±17.1) g/L in 73.9％(102/138), above or equal to 110 g/L and an average Ca×P of (45.2±7.7) mg2/dl2 in 89.1％(123/138), less than or equal to 55 mg2/dl2.Sixty-two patients (44.9％) had progression of kidney disease. On univariate analysis, factors predicting progression were low eGFR at referral, high systolic pressure, low Hb level, high Ca×P and proteinuria during follow-up, and renin-angiotensin system inhibitors treatment did not affect the progression.After the adjustment, multivariate analysis revealed proteinuria and low Hb level were independent factors for the progression of kidney disease.Conclusions The co-morbidities of advanced CKD patients can be managed efficiently in specific CKD outpatient management clinic.Control of proteinuria and correction of anemia may be beneficial to prevent the progression of advanced CKD.

Objective To investigate the influence of comprehensive intervention on improving the quality of life of idiosyncratic infants and young children.Methods A control study Was conducted on 106 idiosyncratic patients aged 6 months to 1 year with specific genetic background,eczema and wheezing under allergen test and comprehensive intervention via a randomized double-blind method.The onset of symptoms and measurement of immunological function were compared after 18 months.Results Serum IgG and IgA increased(all P＜0.05),wheezing and eczema attacks decreased significantly(all P＜0.01),sleep and emotion also improved significantly in the treatment group after 18 months(all P＜0.05).Milk and eggs were the most common allergen for infants and young children.Conclusion Idiosyncrasy and environmental factors were risk factors for allergic diseases.Early childhood was a critical period influencing the occurrence of allergic diseases in children.Early intervention could reduce the incidence of allergic diseases in children and improve the quality of life of idiosyncratic infants and young children.

Objective To investigate the cytokines levels in peripheral blood of ulcerative colitis (UC) patients at active stage, and to observe the effect of baicalin at various concentrations on the cytokines. Methods Quantitative polymerase chain reaction (Q-PCR) assay was used for the detection of interleukin 4 receptor (IL4R), IL6R, IL23R and RAR-related orphan receptor C (RORC) expression in single peripheral mononuclear cell of UC patients. Enzyme-linked immunosorbent assay (ELISA) was used to examine the serum levels of interferon gamma (IFN-γ), IL-4, IL-5, IL-6, IL-10, and transforming growth factor beta (TGF-β) levels in UC patients, and was applied for in-vitro detection of these indicators after baicalin intervention. Results Q-PCR results showed that IL4R, IL6R, IL23R, RORC gene expression levels in UC patients were increased to various degrees as compared to diarrhea-predominant irritable bowel syndrome (IBS-D) patients and the healthy volunteers, and then the levels were decreased to various degrees after intervention by baicalin at different concentrations, in particular at 20 and 40μmol/L. The results of ELISA showed that serum levels of cytokines of IFN-γ, IL-5, IL-6 in UC patients were increased to various degrees while IL-4, IL-10 and TGF-β1 was decreased as compared to IBS-D patients and the healthy volunteers. Baicalin at the concentrations of 20 and 40 μmol/L had an effect on decreasing IFN-γ, IL-5, IL-6 and on increasing IL-4 and IL-10. Conclusion Higher concentrations of baicalin show obvious effect on inhibiting RORC and IL23R expression, on decreasing IFN-γ, IL-5, IL-6 levels, and on increasing IL-4, IL-10 and TGF-β1 levels, which indicated that the therapeutic mechanism of baicalin in relieving ulcerative colonic inflammation is related with the regulation of immune function.

Objective: To study the effect of berberine (BR) on ventricular remodeling in experimental rats with myocardial infarction (MI) and its mechanisms.
Methods: The MI model of experimental rats was established by ligation of the left anterior descending coronary artery and the MI animals were randomly divided into 3 groups: MI+BR group, in which the rats received BR 20 mg/kg.d, Sham group and MI group, the rats in those 2 groups received the same volume of normal saline. All animals were treated for 8 weeks. The cardiac function and structure were assessed by echocardiography, cardiac interstitial collagen deposition was evaluated by Masson stain, the myocardial cell apoptosis was detected by Tunel method, and the activation of nuclear factor (NF-κB) was also examined.
Results: For echocardiography, MI group had enlarged left ventricular end diastolic diameter (7.28 ± 0.29) mm than Sham group (6.86 ± 0.36) mm,P<0.05, but it decreased in MI+BR group (6.89 ± 0.99) mm,P>0.05. MI group had increased left ventricular end systolic diameter (5.88 ± 0.33) mm than Sham group (4.61 ± 0.31) mm, but it decreased in MI+BR group (4.68 ± 1.17) mm, allP< 0.01. MI group showed increased left ventricular posterior wall compensatory hypertrophy (1.81 ± 0.85) mm than Sham group (1.67 ± 0.16 mm),P<0.05, while in MI+BR group, it was deereased to (1.65 ± 0.14) mm. MI group presented decreased LVEF (45.77 ± 3.17) % than Sham group (67.28 ± 4.15) %, but it increased in MI+BR group (64.64 ± 5.82) %, allP<0.01. For Masson stain, cardiac interstitial collagen deposition in MI group (11.39 ± 0.45) % was higher than Sham group (2.65 ± 0.45) %, but less in MI+BR group (7.00 ± 0.87) %, allP<0.01. For Tunel examination, the myocardial cell apoptosis index was increased in MI group (21.31 ± 2.34) than Sham group (0.99 ± 0.38), but decreased in MI+BR group (14.15 ± 1.62), allP<0.01. For NF-κB activation study, the nuclear protein p65 content was higher in MI group (0.14 ± 0.02) ng/ml than Sham group (0.06 ± 0.01) ng/ml, but lower in MI+BR group (0.10 ± 0.02) ng/ml, allP<0.01.
Conclusion: Application of BR may improve the ventricular remodeling and cardiac function in experimental MI rats, it might be because of BR partially inhibit NF-κB activation, reduce collagen deposition and help anti-apoptosis in myocardial cells.

Objective To observe the feasibility of 125I intra-operative implantation plus palliative resection of gastric carcinoma for treatment of advanced gastric cancer infiltrating pancreas. Methods 125 I was implanted intraoperatively into the residual pancreatic cancer tissues after gastric carcinoma was palliatively removed. Results From Feb. 2005 to Jun. 2009, 15 cases (9 male, 6 female) advanced gastric cancer patients were treated with 125 I intra-operative implantation. The patients' ages ranged from 41 to 78 years, with the median age of 64 years old. There were 10 cases of gastric cancer infiltrating the neck or body of pancreas and 5 cases infiltrating pancreatic head. No severe post-operative complications were recorded. The follow-up showed that there were 5 cases of CR (33.3%), 9 cases of PR (60%), 1 case of NC (6.7%) and no PD patients were found. Conclusion 125I intra-operative implantation plus palliative gastric resection is feasible and effective for patients of advanced gastric cancer infiltrating the pancreas.

Metastasis is a multistep process involving modification of morphology to suit migration, reduction of tumor cell adhesion to the extracellular matrix, increase of cell mobility, tumor cell resistance to anoikis, and other steps. MicroRNAs are well-suited to regulate tumor metastasis due to their capacity to repress numerous target genes in a coordinated manner, thereby enabling their intervention at multiple steps of the invasion-metastasis cascade. In this study, we identified a microRNA exemplifying these attributes, miR-124, whose expression was reduced in aggressive MDA-MB-231 and SK-3rd breast cancer cells. Down-regulation of miR-124 expression in highly aggressive breast cancer cells contributed in part to DNA hypermethylation around the promoters of the three genes encoding miR-124. Ectopic expression of miR-124 in MDA-MB-231 cells suppressed metastasis-related traits including formation of spindle-like morphology, migratory capacity, adhesion to fibronectin, and anoikis. These findings indicate that miR-124 suppresses multiple steps of metastasis by diverse mechanisms in breast cancer cells and suggest a potential application of miR-124 in breast cancer treatment.
