Objective To investigate clinical characteristics and risk factors in elderly patients with type 2 diabetes mellitus (T2DM) complicated with chronic kidney disease (CKD).Methods Two hundred and two T2DM patients aged ≥60 y admitted in Tongren Hospital from August 2009 to February 2012 were enrolled in the study,including 64 cases complicated with CKD (CKD group)and 138 cases without CKD (non-CKD group).Hemoglobin (Hgb),albumin (ALB),glycated hemoglobin A1C (HbA1 c),fasting plasma glucose(FBG),postprandial glucose (PBG),serum creatinine (Scr),blood urea nitrogen (BUN),uric acid (UA),total cholesterol (TC),triglyceride (TG),high densitylipoprotein (HDL-C),low density lipoprotein (LDL-C) were measured and ratio of urinary albumin to creatinine (UAER/CR) were calculated,ankle brachial index (ABI) and ambulatory blood pressure was examined.Results The duration of diabetes in CKD group was longer than that in non-CKD group [(13 ± 11) vs.(10 ± 7) y,t =2.35,P ＜ 0.05].Hgb and ALB in CKD group were lower than those in non-CKD group [(12.1 ± 1.7) vs.(13.3 ±1.3) g/L,(34.4±2.6) vs.(36.8 ±3.4) g/L,t=-5.73,-4.75,allP＜0.01]; UA,TG,24 h systolic blood pressure (SBP),24 h pulse pressure (PP)in CKD group were higher than those in non-CKD group [(367 ± 81) vs.(323 ± 74) μmol/L,(1.6 ± 0.9) vs.(1.3 ± 0.7) mmol/L,(133 ± 14) vs.(127±16)mmHg,(65 ±12) vs.(58 ±12)mmHg,t =3.82,2.50,2.47,3.68,all P＜0.1].The UAER/CR in CKD group and non-CKD group was 86.2 mg/g (24.6-374.8 mg/g) and 6.0 mg/g (3.6-17.8 mg/g),respectively (P ＜ 0.01) and ABI in CKD group and non-CKD group was 0.94 ± 0.18 and 1.03 ±0.18 (-2.78,P ＜0.05).There were no significant differences in FBG,PBG,HbA1c,TC,HDL-C andLDL-C between two groups(t =-2.02,1.47,1.48,-0.53,-1.20,-0.76,all P＞0.05).Logistic regression analysis showed that ALB,TG and UAER/CR were the independent risk factors of CKD in T2DM patients(OR:0.79,3.63 and 1.04,95％ CI:0.62-1.01,1.45-9.01 and 1.00-1.08).Spearman correlation analysis demonstrated that eGFR was positively associated with Hgb,ALB,ABI (r =0.38,0.33 and 0.28,all P ＜ 0.01),negatively associated with age,BUN,Cr,UA,TG,UAER/CR,24 hSBP and PP in all diabetes patients(r =-0.32,-0.63,-0.89,-0.34,-0.18,-0.65,-0.16 and -0.248,all P ＜0.01).Conclusions ALB,TG,UAER/CR are the independent risk factors of chronic kidney disease in elderly patients with type 2 diabetes mellitus.

It has been demonstrated that astrocyte elevated gene 1 ( AEG-1 ) can promote tumor initia-tion and progression .Over expression of AEG -1 is correlated with tumor angiogenesis ,metastasis and chemother-apy resistance of tumor cells of different origins .The present article is a review on the mechanism of AEG -1 me-diated drug resistance .Studies have shown that AEG -1 participates in carcinogenesis through Ha -ras,myc,NF-κB and PI3K/Akt signalling pathways .AEG-1 can also promote autophagy through activating AMP Kinase . Other researchers demonstrate that AEG -1 promotes MDR1 protein translation by up-regulating MDR1 mRNA expression ,and thus increases polyribosome .It is testified that AEG-1 can influence drug susceptibility and ex-pression of MDR gene as a RNA binding protein .Multiple functions of AEG -1 in drug resistance in multiple cancers demonstrate that AEG -1 can be used as a novel target for antitumor drugs .

OBJECTIVETo provide evidence for Chinese medical treatment of children with EB virus infection by exploring its clinical efficacy from multiple angles.

METHODSTotally 81 children patients were randomly assigned to the treatment group (46 cases) and the control group (35 cases). Patients in the treatment group took Chinese medical decoction, while those in the control received intravenous dripping of Ganciclovir and oral administration of pidotimod. The treatment period for the two groups was 2 weeks. Patients were followed-up till the 12th week. Clinical symptoms such as fever, lymphadenopathy and hepatosplenomegaly, as well as lab indices such as abnormal lymphocyte percentage, EB virus antibody, virus DNA load, T cell subsets, immunoglobulin, and so on were observed before and after treatment, at week 4 and 12 of follow-ups.

RESULTS(1) The total effective rate at week 2 was 95.6% in the treatment group, higher than that of the control group (94.3%), but there was no statistical difference between the two groups. (2) The time for defervescence, duration of pharyngeal hyperemia, duration of swollen tonsils was shorter in the treatment group than in the control group (P<0.05). The subsidence of lymphadenopathy, hepatomegaly, and abnormal lymphocytes was better in the treatment group than in the control group (P < 0.05). (3) The positive cases of peripheral blood hetero-lymphocyte was significantly reduced after treatment, at week 4 and 12 of follow-ups both in the treatment group and the control group (P < 0.01). The expression of IgA and IgM decreased after treatment in the two groups when compared with before treatment in the same group (P < 0.05, P < 0.01). IgG in the treatment group also obviously decreased after treatment, at week 4 and 12 of follow-ups (P < 0.05, P < 0.01), while it decreased only after treatment in the control group (P < 0.05). Activities of AST and ALT in the treatment group and the AST activity in the control group were markedly improved when compared with those before treatment (P < 0.05). Compared with the control group, the abnormal lymphocyte positive case number obviously decreased in the treatment group after treatment, at week 4 and 12 of follow-ups (P < 0.05). (4) After treatment, at week 4 and 12 of follow-ups, CD3+ and CD8+ significantly decreased; CD4+, CD4/CD8, and B cells significantly increased in the two groups, when compared with before treatment (P < 0.05). NK cells significantly increased more in the treatment group after treatment, at week 4 and 12 of follow-ups, higher than before treatment as well as the control group (P < 0.05). (5) EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the two groups after treatment, at week 4 and 12 of follow-ups (P < 0.05). Compared with the control group, EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the treatment group after treatment and at week 4 of follow-ups (P < 0.05).

CONCLUSIONSTreatment of EB virus infection by Chinese medical treatment was effective. It could promote the recovery of EB viral infection, and reduce the risk of vicious disease after EB viral infection.

Background Glial cell line derived neurotrophic factor (GDNF) is determined to have a neurotrophy effect and promoting effect to the growth of axon.GDNF has been applied in ophthalmology.Research showed that artemin,a new member of GDNF family,has a better function in protection of neuron,but seldom relevant document of distruibution of artemin in retina is found so far.Objective The aim of the present study is to investigate the distribution and expression of artemin in normal rat retinal neuron cells and retinal ganglion cells,and imitate diabetic environment to observe the expression of artemin at the condition of high glucose.Methods Retinal tissue was isolated from clean neonatal SD rats and cultured by expand culture method in DMEM/F12 containing 10% fetal bovine serum.40 mmol/L of glucose was added in medium in the seventh day after culture for 12 hours as experimental group.The expression and location of artemin in retina were tested by real-time PCR and cell immunofluorescence assay.Use of experimental animals followed the Management Regulation of experimental animals of Jiangsu Province.Results Cultured cells showed the typical cell body and processes in the seventh day.Cultured retinal ganglion cells (RGCs) presented the red fluorescence for Thy1.1 antibody,and multiple fluorescence label revealed that RGCs exhibited the green fluorescence for artemin antibody and red fluorescence for Thy1.1 antibody,indicating artemin protein was positively expressed in cultured RGCs.The numbers of positive cells for Thy1.1 antibody was (442±9)/high field in normal culture group and (263±7) /high field in 40mmol/L glucose culture group,showing a significant difference between them (P＜0.05).The expression of artemin mRNA in normal culture group and in 40 mmol/L glucose culture group,was showing a considerably difference between them(P＜0.05).Conclusion Artemin can be expressed in cultured retinal neuron cells and RGCs in rats.High glucose environment down-regulate the expression of artemin.This study proved a new idea for protecting RGCs against damage.

Objective To investigate the application value of virtual touch tissue image technology (VTI) and virtual touch tissue quantification technique (VTQ) in the differential diagnosis of benign and malignant superficial lymph nodes. Methods Fifty superficial lymph nodes were obtained, including 23 for nonspecific inflammatory, 2 for tuberculosis, 5 for lymphoma and 20 for metastasis. All lymph nodes were confirmed by biopsy pathology or follow-up after anti-inflammatory treatments and scanned by traditional ultrasound, VTI and VTQ before resections or treatments. Receiver operating characteristic curve of traditional ultrasound, VTI and VTQ was made to determine the optional cut-off point in the differential diagnosis of benign and malignant superficial lymph nodes and calculate the sensitivity, specificity, accuracy, positive predictive value and negative predictive value. Final diagnosis was defined as the golden standard. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value were calculated by the combined application of traditional ultrasound with VTI and VTQ technology. Results Nine (evaluation value) was taken as the critical value which was scanned by both two-dimensional ultrasound and color Doppler. The ROC curve indicated that the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of conventional two-dimensional ultrasound of benign and malignant lymph nodes were 76.0%, 84.0%, 80.0%, 82.6%, and 77.8%. Taking three (critical value) as the cut-off point, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of VTI in the diagnosis of benign and malignant lymph nodes were 88.0%, 64.0%, 76.0%, 71.0%and 84.2%. Taking 2.755 m/s (shear wave velocity) as the cut-off value, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of VTQ in the differentiation of benign and malignant superficial lymph nodes were 80%, 92.0%, 86.0%, 90.9%and 82.1%. Defined“traditional ultrasound +VTI+VTQ series method” as using conventional ultrasound, VTI, VTQ simultaneously, superficial lymph nodes could be diagnosed with malignant or benign if each method confirmed the same diagnosis. Defined“traditional ultrasound+VTI+VTQ parallel method”as using conventional ultrasound, VTI, VTQ simultaneously, superficial lymph nodes could be diagnosed with malignant if any one method indicated malignancy, otherwise benign. Specificity of‘traditional ultrasound+VTI+VTQ series method’ was consistent with VTQ, which was 92.0%, while the sensitivity and accuracy decreased significantly, which was 64.0%and 78.0%, respectively;the sensitivity and negative predictive value increased significantly by using “traditional ultrasound +VTI+VTQ parallel method” when compared with traditional ultrasound, VTI or VTQ, almost near 100%, but declined significantly in specificity and accuracy, which was 64.0%and 82.0%, respectively. Conclusions Traditional ultrasound, VTI and VTQ have certain clinical value for differential diagnosis of benign and malignant superficial lymph nodes. Combined application of traditional ultrasound, VTI and VTQ can improve the accuracy in the diagnosis of benign and malignant lymph nodes effectively.

Objective To investigate effects of Kanglaite injection on proliferation, cycle and apoptosis of human breast cancer MCF-7 cells;To discuss its relevant mechanism. Methods Logarithmic growth phase cells were divided into control group and Kanglaite-treatment group (10, 20, 40μL/mL). Cells were cultured in RPMI-1640 for 24 h before drug treatment. The inhibition rate of Kanglaite injection on proliferation of human breast cancer MCF-7 cells was detected by MTT assay. Apoptosis and cell cycle of MCF-7 cells were detected by flow cytometry. Changes in cell nucleus were determined by Hochest staining assay. Protein expressions of Bcl-2 and Bax were detected by ELISA and Western blot. Results Kanglaite injection for 12 h, 24 h or 48 h resulted in a significant inhibition of MCF-7 cells proliferation (P<0.05, P<0.01);Compared with the control group, Kanglaite injection-treated cells showed increased percentage in G2/M and G0/G1 phases (P<0.001, P<0.01), but showed decreased percentage in S phase (P<0.01), and apoptosis rate increased (P<0.05, P<0.001). Kanglaite injection significantly decreased protein expression of Bcl-2, and enhanced protein expression of Bax of MCF-7 cells (P<0.01, P<0.001). Conclusion Kanglaite injection can inhibit the proliferation of human breast cancer MCF-7 cells, decrease cell cycle and induce apoptosis, the mechanism is related with decreasing protein expression of Bcl-2 and enhance the protein expression of Bax.
