To explore the risk factors of acute kidney injury(AKI)in adult primary nephrotic syndrome(PNS). Totally 185 patients with PNS were divided into AKI group(=51)and non-AKI group(=134).The demographic data and clinical and histological features at admission were compared between the two groups.The independent risk factors for AKI were evaluated by Logistics regression analysis. In 51 PNS patients with AKI,the common pathological types of AKI included minor glomerular abnormalities(29.4%),IgA nephropathy(25.5%),and membranous nephropathy(17.6%).The incidences of renal tubular casts and epithelial vacuoles in the AKI group were significantly higher than those in the non-AKI group(=0.004,=0.030).Males were more likely to suffer from AKI than females(=0.000).Patients in AKI group had significantly lower albumin level(=0.015)and higher levels of random urine protein,serum creatinine,uric acid,urea nitrogen,and triglyceride than non-AKI group(=0.030,=0.000,=0.000,=0.000,and =0.006),and polyserous and oliguria occurred more often in the AKI group(=0.000,=0.002).The AKI group had significantly higher incidences of high blood pressure and infections(=0.035,=0.000).Multivariate logistics regression analysis showed albumin(<25 g/L),serum creatinine(>96 μmol/L),urea nitrogen(≥6.8 mmol/L),uric acid(≥400 μmol/L),diabetes,infection,and renal tubular casts were the independent risk factors for AKI. AKI complicating PNS is associated with a variety of factors.Its independent risk factors include the levles of albumin,serum creatinine,urea nitrogen,and uric acid,diabetes,infections,and renal tubular casts.

Aim To explore the interaction between nitric oxide( NO) and hydrogen sulfide(H 2S) on the relaxation reactivity of pulmonary arteries in rats.Methods Seven male healthy rats were anaesthesed with chloral hydrate; the pulmonary artery of each rat was removed for the study. Th e reactivities of pulmonary artery rings in response to different doses of NO do nar-sodium nitroprusside(SNP) and H 2S donar-NaHS were measured in vitro.DL-propargylglycine(PPG)and N?-nitor-L-methyl ester(L-NAME) were provided to pulmonary artery, respectively;the relaxation reactivities of pulmonary artery were observed.Results The relaxation reactivities of pulmonary arteries showed a dose-dependent increase in response to different doses of SNP and H 2S.The relaxation reactivity to SNP decreased by PPG. The relaxation reactivity to H 2S decreased by L-NAME.Conclusion H 2S acted as a vasorelaxator either independently or accompanied with NO, SNP acted as a vasorelaxator either independently or accompanied with H 2S;the networ k of gastransmitter played an important role in the relaxation of pulmonary arte ries.

AIM: To isolate targeted the peptides that binding and internalizing into endometrial carcinoma cell line EAC. METHODS: The tumor cells were screened five rounds of whole cell screen through the Ph.D.-12 phage display library. Analysis of the displayed peptides specific binding efficiency to the tumor cells was proceeded. The DNA of phages was extracted, sequenced and translated to the sequences of amino acid and analysis using computer software. RESULTS: After five biopannings, the isolated phages showed high specificity and strong affinity for their cognate cell types relative to different cell lines. Through sequencing, the sequences of displayed peptides were obtained. CONCLUSIONS: Whole cell screening against EAC cells through random phage peptide library can obtain phage peptides with a highly tissue specific binding and internalizing ability. The peptides do provide a basis for tumor's targeted delivery as therapy vector.

Objective To estimate the prevalence and associated factors of adult female urinary incontinence in Hebei province. Methods Stratified and multistage sampling method was used, between January 2016 to May 2016, to investigate the target population in Hebei province. While, logistic regression was used to analyse datas. Results A population-based survey was conducted in 2 450 women in Hebei province, there were 2 408 effective questionnaires after deleting 48 invalid questionnaires. According to the results, the average age of subjects was (56±15) years old, and the urinary incontinence prevalence of adult female in Hebei province was 27.70%(667/2 408). Stress urinary incontinence, urge urinary incontinence and mixed urinary incontinence were diagnosed as 23.13%(557/2 408), 1.58%(38/2 408) and 2.99%(72/2 408), respectively. There were only 2.85% (19/667) urinary incontinence patients seeking medical help. The results of logistic regression analysis showed that age, daily water intake, pulmonary diseases, urinary tract infection, hypertension, chronic low back pain, dysmenorrhea, vaginitis, abortion, mode of delivery, postpartum infection were statistically significant (all P≤0.05). Among these factors, cesarean section was the protective factor for urinary incontinence (OR=0.365, 95%CI: 0.195-0.685, P<0.01). Conclusions The prevalence of urinary incontinence in adult female in Hebei province is high, and there are few patients seeking medical help. It is a common disorder in women and is associated with many factors;among these factors, cesarean section is the protective factor for urinary incontinence.

To explore the effect of advanced glycation end-products(AGEs)on cell viability and level of reactive oxygen species(ROS)in MIN6 cells. After intervention of various concentrations(100,200, and 400 mg/L)of AGEs for some time, cell viability was detected by MTT assay. 2', 7'-dichlorofluorescein diacetate(DCFH-DA)was used as a reactive oxygen species capture agent. The fluorescent intensity of 2', 7'-dichlorofluorescein(DCF), which was the product of cellular oxidation of DCFH-DA, was detected by flow cytometry. The level of ROS and insulin secretion was thus measured. Viability of MIN6 cells was inhibited by AGEs in a dose and time dependent manner(P＜0.05).Intracellular fluorescent intensity of DCF was markedly elevated in the AGEs groups as compared with that in the control group(P＜0.05).Insulin secretion was decreased in the AGEs groups than that in the control group(P＞0.05). The results suggest that AGEs inhibit the viability and induce oxidative stress in MIN6 cells by overproduction of ROS.

The effects of tumor suppressor in lung cancer-1(TSLC1)upregulation on gene expressions involved in glucose and lipid metabolism in Hepa1-6 cells were investigated.The results showed that TSLC1 overexpression decreased fatty acid synthase and acetyl CoA carboxylase expressions(P<0.05 or P<0.01),increased adipose triglyceride lipase expression(P<0.05),and did not change hormone-sensitive lipase,glucose transporter (GLUT)1,and GLUT4 expressions.These results suggest that TSLC1 overexpression may promote lipolysis and inhibit adipogenesis in liver cells.

OBJECTIVETo summarize the clinical characteristics of an infant with chronic myelogenous leukemia (CML) and the effects of imatinib on the case.

METHODThe clinical features of an infant with CML, who was treated with imatinib in the Norman Bethune International Peace Hospital at June 2009, were retrospectively analyzed and the reports in literature were reviewed. The 1-year-old boy suffered from recurrent low-degree fever and pallor. He had a moderate anemia, distended abdomen and marked splenomegaly. Bone marrow aspiration revealed CML in chronic phase)CP). The t (9; 22))q34; q11) could be detected and BCR-ABL (p210) was positive. The boy was diagnosed as CML-CP and treated with imatinib 100 mg per day. There were 10 related papers and more than 100 child CML patients were reported as retrieved from CNKI)from its establishment to August 2014) and Wanfang Database)from its establishment to August 2014) when "Child", " Chronic" and "Leukemia" were used as keywords. And there were 30 related papers including 400 cases from PubMed Database (from its establishment to August 2014) and one detailed report of an infant with CML was retrieved when "childhood" and "chronic myeloid leukemia" "imatinib" were used as keywords. The clinical effects of imatinib in infant CML cases were analyzed and summarized based on the literature.

RESULTThe boy obtained a complete hematologic response (CHR) at the 6th week of diagnosis, a complete cytogenetic response (CCyR) at the 3rd month and a complete molecular response)CMR) at the 12th month without side effect. This boy grows very well and after a 62-month follow-up, his disease was stable. According to the domestic literature, 5 children CML cases aged 6 -12 years were treated with imatinib without side effects and got complete hematologic response (CHR) after 2-month-therapy. The dose, metabolic characteristics and clinical observation of imatinib can be found in foreign literature and imatinib showed good response with good tolerance in children with CML. Imatinib is regarded as the first line drug for children CML. But it may affect the development of the children.

CONCLUSIONThe children with CML-CP had a good response to imatinib, but more experience in the treatment of children with CML with iniatinib is needed.
