Objective To investigate the expression and diagnostic significance of CK19,CD56 and p53 protein in papillary thyroid microcarcinoma and thyroid papillary hyperplasia.Methods The expressions of CK19、CD56 and p53 protein were detected in 52 cases of papillary thyroid microcarcinoma and 31 of thyroid papillary hyperplasia by iImmunohistochemical methods.Results The positive rate of CK19 expression was 100 ％ (52/52) of papillary thyroid microcarcinoma and 29.0 ％ (9/31) in 31 of thyroid papillary hyperplasia.There was significant difference between two groups (P ＜ 0.001).CK56 in 2 cases (3.8 ％) of papillary thyroid microcarcinoma appeared mild positive expression,and in 20 cases (66.7 ％) of thyroid papillary hyperplasia positive expression (P ＜ 0.001).The positive expression rates of p53 were 69.2 ％(36/52) in papillary thyroid microcarcinoma and 6.5 ％ (2/31) in thyroid papillary hyperplasia (P ＜ 0.001).Conclusion CK19,CD56 and p53 may be important value on differential diagnosis of papillary thyroid microcarcinoma from thyroid papillary hyperplasia,and they are the indispensable markers of differential diagnosis.

Objective To explore the expression and the role of Toll-like receptor(TLR3 and TLR4) in rats with nephrotic syndrome induced by respiratory syncytial virus(RSV).Methods SD rats were inoculated intranasally and intraperitoneally with 6?106 plaque for-ming unit(PFU) RSV to construct RSV-induced nephropathy in rat model.Rats were anesthetized and blood was withdrawn from cardiac on day 4,14,30,60 after inoculation.The normal ones without intervention were set as control group.The renal histology was observed by light microscope and electron microscope.The urinary protein collected in 24 hours were measured.Meanwhile,the expressions of TLR3 and TLR4 were detected by indirect immunofluorescence staining and flow cytometry in peripheral blood mononuclear cells of rats.The results were analyzed by SPSS 13.0 softwore.Results After inoculation,the proteinuria increased and under the electron microscope the foot processes of glomerular epithelial cells were fused which resembled human minimal change nephrotic syndrome.Proteinuria reached the peak and the fusion of foot processes were most extensive in rats of RSV at 60 d.The expressions of TLR3 and TLR4 in each group of RSV-induced nephropathy in rat models were significantly higher than those in normal control group(Pa0.05).Conclusions TLR3 and TLR4 in peripheral blood mononuclear cells of RSV-induced nephropathy rat mo-dels had being significantly activated until 60 d after RSV inoculation.TLR signaling pathway may play an important role in nephrotic syndrome of rats induced by RSV.

Objective To evaluate pigtail catheter mashing thrombosis combined with catheter directed thrombolysis in the treatment of acute iliofemoral venous thrombosis complicated by Cockett syndrome in the left lower limbs.Method Data of 137 cases of acute iliofemoral venous thrombosis complicated with Cockett syndrome in left lower limb by interventional therapy from January 2007 to October 2012 were analyzed retrospectively.Inferior vena cava filters were placed in all of the patients.Patients were divided into two groups:Group A (n =81) treated with catheter directed thrombolysis only,Group B (n =56) treated with pigtail catheter mashing thrombosis combined with catheter directed thrombolysis.After operation,patients were treated by anticoagulation with urokinase and heparin calcium,and then warfarin for 6 to 1 2 months.Results The thrombolysis time in group B was significantly shorter than that in group A (P ＜0.01),the dosage of urokinase was significantly less than that in group A(P ＜ 0.01).The venous patency score in group B after therapy was significantly better than in group A (P ＜ 0.01).121 patients were followed up for 10-60 months.There were no pulmonary embolism.Conclusions Pigtail catheter mashing thrombosis combined with catheter directed thrombolysis in the treatment of acute iliofemoral venous thrombosis complicated with Cockett syndrome in left lower limb can improve thrombolytic efficiency,shorten thrombolysis time,reduce the use of urokinase.

Aim The expression of NF-?B activation and the effect of antioxidant (N- acetylcysteine, NAC) on NF-?B activity in human airway epithelial cell was assessed. Methods Using the TNF-?,the airway epithelial cell strains of normal subject(16HBE) and tumor patient (H292) was activated and using Western-Blot and ELISA the expression of NF-?B and IL-8 were detected. Results It was found that the activity of NF-?B could be stimulated by the TNF-? and increase with the amount of TNF-? with the peak occurring at 2 to 4 hours after stimulation and then decreasing at six hours. At the same time, the level of IL-8 was elevated, but decreased with inhibition of NF-?B activity by NAC, that means the action of NAC has a dose-dependent effect. Conclusion NAC not only blocks the signal transmission activated by NF-?B, but also anticipates the transcription modulation of expression of many cell factors and inflammatory mediums. It suggests that NAC may play a role in the anti-inflammatory treatment of respiratory diseases.

OBJECTIVETo observe the therapeutic effect of xiaoke shen' an capsule on diabetic nephropathy.

METHODSNinety patients with diabetic nephropathy were randomly divided into two groups, the patients in the control group (CG) were treated with conventional western medicine, and those in the treated group (TG) were treated with combined therapy of xiaoke shen'an capsule and conventional western medicine. The treatment course of both groups was 8 weeks, and the therapeutic effect related indexes were measured before and after treatment.

RESULTSThe curative rate was 85.0% and 73.3% in CG and TG respectively, it was better in TG than that in CG (P < 0.05). Indexes such as fasting blood glucose, glycosylated hemoglobin, blood pressure, quantity of 24h urinary protein, urinary albumin excretion rate, renal function, blood lipids and hemoreheologic parameters were significantly different before and after treatment in TG (P < 0.05 or P < 0.01). As compared with CG, some of these indexes after treatment were superior to those in CG (P < 0.01 or P < 0.05).

CONCLUSIONCombined therapy of xiaoke shen'an capsule and conventional western medicine has definite therapeutic effect on diabetic nephropathy.

OBJECTIVETo investigate the effects of nano-lead exposure on learning and memory and iron homeostasis in the brain of the offspring rats on postnatal day 21 (PND21) and postnatal day 42 (PND42).

METHODSTwenty adult pregnant female Sprague-Dawley rats were randomly divided into control group and nano-lead group. Rats in the nano-lead group were orally administrated 10 mg/kg nano-lead, while rats in the control group were administrated an equal volume of normal saline until PND21. On PND21, the offspring rats were weaned and given the same treatment as the pregnant rats until 42 days after birth. The learning and memory ability of offspring rats on PND21 and PND42 was evaluated by Morris water maze test. The hippocampus and cortex s amples of offspring rats on PND21 and PND42 were collected to determine iron and lead levels in the hippocampus and cortex by inductively coupled plasma-mass spectrometry. The distributions of iron in the hippocampus and cortex were observed by Perl's iron staining. The expression levels of ferritin, ferroportin 1 (FPN1), hephaestin (HP), and ceruloplasmin (CP) were measured by enzyme-linked immunosorbent assay.

RESULTSAfter nano-lead exposure, the iron content in the cortex of offspring rats on PND21 and PND42 in the nano-lead group was significantly higher than those in the control group (32.63 ± 6.03 µg/g vs 27.04 ± 5.82 µg/g, P<0.05; 46.20 ±10.60 µg/g vs 36.61 ± 10.2µg/g, P<0.05). The iron content in the hippocampus of offspring rats on PND42 in the nano-lead group was significantly higher than that in the control group (56.9 ± 4.37µg/g vs 37.71 ± 6.92µg/g, P<0.05). The Perl's staining showed massive iron deposition in the cortex and hippocampus in the nano-lead group. FPNl level in the cotfex of offspring rats on PND21 in the nano-lead group was significantly lower than that in the control group (3.64 ± 0.23 ng/g vs 4.99 ± 0.95 ng/g, P<0.05). FPN1 level in the hippocampus of offspring rats on PND42 in the nano-lead group was significantly lower than that in the control group (2.28 ± 0.51 ng/g vs 3.69 ± 0.69 ng/g, P<0.05). The escape latencies of offspring rats on PND21 and PND42 in the nano-lead group were longer than those in the control group (15.54 ± 2.89 s vs 9.01 ± 4.66 s; 6.16 ± 1.42 s vs 4.26 ± 1.51 s). The numbers of platform crossings of offspring rats on PND21 and PND42 in the nano- lead group were significantly lower than those in the control group (7.77 ± 2.16 times vs 11.2 ± 1.61 times, P<0.05; 8.12 ± 1.51 times vs 13.0 ± 2.21 times, P<0.05).

ONCLUSIONn Nano-lead exposure can result in iron homeostasis disorders in the hippocampus and cortex of offspring rats and affect their learning and memory ability.
