Objective To investigate the level of serological interleukin 35 (IL-35) in breast cancer patients and its clinical significance.Methods From Jan 2015 to July 2016,serum of 55 patients with breast cancer were collected from a tertiary hospital of Nanjing.Their pathological stages were also analyzed,including 12 cases of stage Ⅰ,15 cases of stage Ⅱ,12 cases of stage Ⅲ,and 15 cases of stage Ⅳ.Meanwhile,serum from 54 healthy individuals also selected.The level of serological IL-35 was determined by ELISA,and the IL-35 level,pathological stage and tumor metastasis were analyzed by correlation a nalysis.Results The serum IL-35 in patients with breast cancer was significantly elevated than health individuals.With the increase in pathological stage,IL-35 level in breast cancer patients with stage Ⅲ and Ⅳ was significantly higher compared to patients with stage Ⅰ breast cancer (P＜0.05).Further,patients with breast cancer metastasis had increased level of IL-35,compared to breast cancer patients without tumor metastasis (P＜ 0.05).Finally,Spearman correlation analysis indicated that the serum level of IL-35 in patients with breast cancer was positlvely correlated with the pathological stages (r=0.390,P=0.004) and tumor metastasis (r=0.361,P=0.008) of the patients,respectively.Conclusion High level of IL-35 was detected in serum from breast cancer patients,and its expression was highly correlated with pathological stage and tumor metastasis.Detection of IL-35 could be applied as a valuable potential biomarker for the diagnosis of breast cancer.

Objective To investigate the expression and clinical significance of zinc finger protein 217 (ZNF217)in human pancreatic cancer.Methods 43 cases with pancreatic cancer undergoing surgery in the PLA 117 Hospital and People's Hospital of Ruian City from Apr .2011 to May.2014 were enrolled in the study . The pancreatic cancer and the corresponding tumor-adjacent tissues were collected .Real-time quantitative PCR (qRT-PCR)was applied to detect ZNF217 mRNA expression in pancreatic cancer (n=43)and the corresponding tumor-adjacent normal tissues.The protein expression of ZNF217 was measured by immunohistochemistry(IHC). The relationship between the expression of ZNF 217 and clinical features was analyzed by pearson chi-square test . Results The expression level of ZNF217 mRNA and protein was significantly higher in pancreatic cancer tissues than in adjacent normal tissues(P<0.05).The high expression of ZNF217 protein was positively correlated with perineural invasion, tumor size, lymphatic metastasis and advanced TNM stage (P<0.05).Conclusions The expression of ZNF217 is significantly higher in pancreatic cancer tissues than in tumor-adjacent normal tissues , and the upregulation of ZNF 217 is associated with clinicopathological features of tumor malignance .ZNF217 may become a new marker and effective therapeutic target in early diagnosis of pancreatic cancer .

Objective To investigate the clinical value of urinaryα1-acid glycoprotein (AAG)in the early diagnosis of diabetic nephropathy(DN).Methods 266 cases of diabetic patients in Drum Tower Hospital Affiliated to Medical School of Nanjing University from May 2013 to October 2014 were recruited,and patients were divided into four groups based on the urine al-bumin/creatinine (ACR)levels,as follows:non-diabetic nephropathy group (Non-DN)152 cases,low urinary albumin/cre-atinine group (LUA)49 cases,high urinary albumin/creatinine group (HUA)32 cases,and very high urinary albumin/cre-atinine group (VHUA)33 cases.63 cases of healthy subjects (NC group)and 66 cases of fracture patients (stress group) were recruited as control group.The urinary AAG and other biochemical indicators were measured for all subjects.Results The level of urinary AAG in DN group was significantly higher than that in stress group,Non-DN group and NC group (t=7.951,7.985,8.021,P <0.05),and gradually increased from LUA,HUA to VHUA group (P <0.05).The urinary AAG level was positively correlated with UA,Cr,CRP and ACR (r=0.169,0.286,0.373,0.606,P <0.01).Stepwise logistic re-gression analysis showed that the urinary AAG was the independent risk factor of DN (P <0.05).Conclusion The level of urinary AAG has good application value in the early diagnosis and monitoring progression of DN.

Objective To study the iodine nutritional status and the thyroid function of pregnant women during different periods,and provide scientific basis for iodine supplementation.Methods Totally 728 pregnant women who visited the obstetric outpatient of Nanjing Drum Tower Hospital for routine prenatal care from December 2014 to August 2016 were recruited in this study,and at the same time 182 non-pregnant women were recruited as control group.The thyroid stimulating hormone (TSH) and free thyroxine (FT4) were measured by Roche 601.The urinary iodine level was measured by SR-I-100 kit.Results The median urinary iodine of 728 pregnant women was 168.24 g/L,and the median urinary iodine of those women in the T1,T2 and T3 period were 186.31,162.65 and 148.76 g/L,respectively.The TSH at T1 period was lower than T2 and T3 period (t=3.429,3.135,P＜0.05).The FT4 at T1 period was higher than T2 and T3 period (t=5.251,5.965,P＜ 0.05).The prevalence rate of thyroid disease in normal urinary iodine group was lower than that in low urinary iodine group and high urinary iodine group (x2 =4.139,4.131,P＜0.05).Conclusion There was no iodine deficiency among those pregnant women groups,but only 34.75 ％ individuals reached the appropriate iodine nutritional level,and the ratio of iodine insufficient increased with the extension of pregnancy.The whole prevalence rate of thyroid disease in abnormal urinary iodine pregnant women was obviously higher than that in normal.It is necessary to improve the pregnant women's knowledge of iodine nutrition,moreover it is suggested that urinary iodine monitoring and thyroid function should be conducted in pregnant women.

Objective To explore the molecular mechanisms of carbapenem-resistant Klebsiella pneumoniae.Methods Carba NP confirmatory test were used to detect carbapenemases.Carbapenemase genes,ESBL genes and plasmid-mediated AmpC genes were amplified by polymerase chain reaction (PCR).The genetic correlation analysis was carried out by using multiple sequence type (MLST).Results 42 out of the 50 carbapenem-resistant Klebsiella pneumoniae strains were KPC-2-positive strains,1 strain was positive for NDM-1,the other 7 strains were not detected for any carbapenemase genes.The percentages of KPC-2-positive Klebsiella pneumoniae with the bla CTX-M,bla SHV,bla TEM,bla DHA were 21.5 ％,42.9 ％,69.1％ and 4.8％ respectively.The results of MLST showed that 37 out of 42 KPC-2 positive strains were ST11.Conclusion The production of KPC-2 is the main mechanism of Klebsiella pneumoniae resistance to carbapenem and there is an outbreak of ST11 KPC-2 Klebsiella pneumoniae in this hospital.

Objective · To investigate the clinical characteristics and multidisciplinary treatment of children with clear cell sarcoma of kidney (CCSK). Methods · Data of seven children with CCSK treated at Xinhua Hospital, Shanghai Jiao Tong University School of Medicine between Jan 2011 and Jan 2016 were collected. The retrospective analysis of clinical manifestations, features of imaging and pathology, treatment, and follow-up was performed. Results · Of 7 children with CCSK, 6 were male and 1 was female with the median age of 28 months (4-59 months), and 3 were at stageⅠ, 2 at stage Ⅲ, and 2 at stage Ⅳ. All cases were discussed and evaluated by multidisciplinary teams, including pediatric hematology/oncology, pediatric surgery, pathology, radiology and radiotherapy. CCCG-WT-2009 protocol was adopted to treat these patients. The median follow-up period was 22 months (8-56 months). Six children survived and one died. Conclusion · The multidisciplinary treatment mode can effectively improve the prognosis of CCSK. CCCG-WT-2009 protocol has good therapeutic effect and high cure rate for children with early stage CCSK, but the treatment of advanced stage CCSK needs to be further explored and perfected.
