Purpose To investigate the imaging features of breast phyllodes tumor on mammography(MG),ultrasound(US) and pathology, correlated with its clinical manifestation.Materials and Methods Twelve cases of pathologically confirmed breast phyllodes tumors were examined by US and MG. The imaging findings were retrospectively analyzed. Results Of the 12 cases of breast phyllodes tumors, 6 were benign, 3 were malignant and 3 were borderline. MG predicted 3 breast phyllodes tumors, 3 breast carcinomas and 6 adenomas. US predicted 2 phyllodes tumors, 8 breast masses and 2 adenomas. Conclusion The imaging findings of phyllodes tumors on MG and US are characteristic but not specific. Combined application of both US and MG are helpful for early detection but can not differentiate its malignancy which is determined by pathology.

Objective To explore basic regularities in sinew lesion distribution in patients with knee osteoarthritis. Method Two hundred and thirty knee osteoarthritis patients with 253 affected knees were selected. Under the sinew theory, the positions and frequency of sinew foci around the knee joint were counted by palpation. Result In the distribution of foci, the total frequency accounted for 39.1% in the Foot-Yangming. Of them, the single Foot-Yangming sinew type accounted for 23.3% and the complex type accounted for 48.5%. The total frequency accounted for 32.4% in the Foot-Taiyang. Of them, the single Foot-Taiyang sinew type accounted for 21.3%, the complex type accounted for 44.5%. The Foot-Yangming + Foot-Taiyang sinew lesions accounted for 14.6% and the single foot-three-yin sinew type accounted for 15.0%. Conclusion Knee osteoarthritis of Foot-Yangming or Foot-Taiyang sinew type should be treated from “sinew”.

OBJECTIVE:To investigate the characteristics and regularity of lornoxicam related ADR,and to provide reference for rational and safe use of lornoxicam. METHODS:From Jan. 1,2006 to Dec. 31,2013,lornoxicam related ADR reports collect-ed by National ADR Monitoring System in Beijing were analyzed retrospectively about their characteristics and related factors. RE-SULTS:In the statistical period,there were 48 ADR reports related to lornoxicam. The people over 40 years age accounted for 62.5%. 38 patients used lornoxicam by intravenous infusion or intramuscular injection ,accounting for 79.17%. The clinical mani-festations were diverse and complex,in which skin(32.96%)and gastrointestinal damage(25.00%)were more common ADR oc-curred within 30 min,accounting for 35.42%,and it would be better after stopping drug or 1-3 days symptomatic treatment. CON-CLUSIONS:The rational use of lornoxicam can reduce the occurrence of ADR. Suggestion on the use of the drug,is that the pa-tient should be monitored for security,in order to reduce the risk of ADR.

ObjectiveTo investigate the protective effect of combination of triptolide and irbesartan on the podocytes in a type 2 diabetic(T2DM) rat model,and evaluate its mechanism.Methods T2DM rats were induced by fed with high-sucrose-high-fat diet combined with a low dose of streptozocin.The rats were randomly divided into 5 groups:normal control group ( NC,n =10),diabetes group ( DM,n =11),triptolide treatment group (DT,n =12),irbesartan treatment group (DI,n =12) and triptolide combined with irbesartan treatment group (DTI,n =13). Ultrastructure of podocytes was observed by electronic microscopy and urinary albumin (UAL) excretion by ELISA was determined after 8 weeks.The expression of nephrin and bone morphogenetic protein-7(BMP-7), connective tissue growth factor (CTGF),transforming growth factor (TGF)β1 mRNA and proteins were detected by immunohistochemistry,real-time PCR and Western blot. Results Increased UAL was significantly attenuated in all treatment groups.Compared to NC group,UAL in DM group was increased significantly (0.45 ± 0.09 vs 6.36 ± 0.87,P ＜ 0.01 ),while decreased in triptolide or irbesartan alone treatment group (2.48 ± 0.37 and 2.68 ±0.42,both P ＜ 0.01 ).Compared with those in control groups,kidney expression of nephrin,BMP-7 mRNA and proteins were downregulated while CTGF, TGFβ1 mRNA and proteins were significantly upregulated in T2DM rats. Triptolide or irbesartan each alone moderately ameliorated albuminuria and podocyte damage.However,their combined usage showed a dramatic therapeutic synergism,manifested by prevention of progressive albuminuria,restoration of the glomerular filtration barrier,reversal of the decline in slit diaphragm proteins,reduction expression of CTGF,TGFβ1,and upregulation of BMP-7.Conclusion Our findings show that triptolide can increase the efficacy of irbesartan,leading to a more effective prevention of kidney disease in T2DM rat model,which may through upregulation of BMP-7 and inhibition the overexpression of CTGF and TGFβ1.

Objective To explore the clinical characteristics of IgG4-related disease (IgG4-RD) in Chinese by detailed clinicopathological and laboratory assessments.Methods The baseline features of 36 patients with biopsy-proven disease were reviewed.The diagnosis was confirmed by pathology review according to consensus diagnostic criteria and clinicopathologic correlation.Disease activity and damage were assessed by the IgG4-RD responder index (RI).Results Thirty (83.3％) of the patients were male,while six were female,and the average age of onset was 65.1 years.All of the 36 patients had active disease,in which submandibular gland,lymph nodes,retroperitoneal tissue were the most common affected organs in this group of patients.Among 36 patients,77.7％ had elevated serum IgG4 concentrations and 44.4％ had hypocomplementemia.Patients with elevated serum IgG4 had a higher RI,a greater number of organs involved (P ＜ 0.01 for all comparisons).The correlation between serum IgG4 level and RI (r=0.737,P ＜ 0.01) was stronger than IgG,ESR,CRP and serum complement levels.The incidence of hypocomplementemia in IgG4-RD patients with renal involvement was higher than that in IgG4-RD patients with other organs involvement (P ＜ 0.01).Twenty-eight patients received glucocorticoids therapy,and had lower RI and serum IgG4 concentration after therapy (P ＜ 0.05).Conclusions Both IgG4-RD RI and IgG4 concentration may be regarded as assessment markers of disease activity and therapeutic effect of IgG4-RD.The diagnosis of IgG4-RD should be supported by histopathology and clinical features.

Objective To investigate the correlation between fatigue and coping strategies among peritoneal dialysis patients,to improve their health consciousness and reduce the fatigue.Methods A total 107 patients were surveyed with general data questionnaire,Multidimensional Fatigue Symptom Inventory-Short Form( MFSI-SF) ,and Medical Coping Modes Questionnaire,MCMQ.Results The score of fatigue was (83.32 ±1.54) points,which indicated the fatigue remained in high level.Scores from high to low were dialysis≥5years,dialysis<1year and 1year≤dialysis<5years.Patients mainly took the coping style with positive face.Pearson correlation analysis showed that fatigue was negatively correlated withface(r=-0.300,P<0.05),while it was positively correlated with withdrawand yield(r=0.227,0.300,all P<0.05).Conclusion Patiens should be encouraged to actively face the disease,pay more attention to their own state of dialysis and improve the effect of drain,reduce fatigue,then to reply for both mind and body health.

Objective To study the expression of RhoA and C-myc in gastric carcinoma , and to discuss the action in infiltration and metastasis of gastric carcinoma as well as their dependability. Methods RhoA protein expression and C-myc protein expression were detected by immunohistochemical method in 46 cases of gastric carcinoma and 20 cases of normal tissues..RhoA protein expression was compared with clinical pathologic parameters as related to C-myc. Results The positive rate of RhoA,C-myc were significantly higher in gastric carcinoma than in normal tissue (P < 0.05). The expression of RhoA and C-myc were associated with the loss of tumor differentiation, lymph node metastasis and deep invasion (P<0.05). There was a significant correlation between RhoA and C-myc (r=0.62, P<0.05). Conclusions The data suggests that the expression level of RhoA protein was closely related to biological behavior of gastric carcinoma. RhoA and C-myc were possibly both correlated with the infiltration and metastasis of gastric carcinoma.

AIM:Tostudywhe ther theangiotens in-(1-7)[Ang-(1-7)]/Mas receptor axis protects cardio-myocytes against high glucose (HG)-induced injury by inhibiting nuclear factor-κB (NF-κB) pathway.METHODS:The cell viability was measured by CCK-8 assay.The intracellular levels of reactive oxygen species ( ROS) were detected by DCFH-DA staining .The number of apoptotic cells was tested by Hoechst 33258 nuclear staining .Mitochondrial membrane potential ( MMP) was examined by JC-1 staining.The levels of NF-κB p65 subunit and cleaved caspase-3 protein were de-termined by Western blotting.RESULTS: Treatment of H9c2 cardiac cells with 35 mmol/L glucose (HG) for 30, 60, 90, 120 and 150 min significantly enhanced the levels of phosphorated ( p) NF-κB p65, peaking at 60 min.Co-treatment of the cells with 1 μmol/L Ang-(1-7) and HG for 60 min attenuated the up-regulation of p-NF-κB p65 induced by HG. Co-treatment of the cells with Ang-(1-7) at concentrations of 0.1~30μmol/L and HG for 24 h inhibited HG-induced cy-totoxicity, evidenced by an increase in cell viability .On the other hand, 1 μmol/L Ang-(1-7) ameliorated HG-induced apoptosis, oxidative stress and mitochondrial damage , indicated by decreases in the number of apoptotic cells , cleaved caspase-3 level, ROS generation and MMP loss .However, the above cardioprotective effects of Ang-(1-7) were markedly blocked by A-779, an antagonist of Ang-(1-7) receptor (Mas receptor).Similarly, co-treatment of H9c2 cardiac cells with 100 μmol/L PDTC ( an inhibitor of NF-κB) and HG for 24 h also obviously reduced the above injuries induced by HG.CONCLUSION:Ang-(1-7)/Mas receptor axis prevents the cardiomyocytes from the HG-induced injury by inhibiting NF-κB pathway .

AIM:To investigate the roles of ATP-sensitive potassium ( KATP ) channels in high glucose-induced cardiac injury and the inhibitory effect of hydrogen sulfide ( H2 S) on the cardiomyocyte injury.METHODS:The expres-sion level of KATP channel protein was tested by Western blot.The cell viability was measured by CCK-8 assay.The number of apoptotic cells was observed by Hoechst 33258 nuclear staining.Mitochondrial membrane potential ( MMP) was exam-ined by JC-1 staining.RESULTS:After the H9c2 cells were treated with 35 mmol/L glucose ( high glucose, HG) for 1~24 h, the protein level of KATP channel was significantly reduced at 6 h, 9 h, 12 h and 24 h, reaching the minimum level at 12 h and 24 h.Pretreatment of the cells with 400μmol/L NaHS ( a donor of H2 S) prior to exposure to HG for 12 h con-siderably blocked the down-regulation of KATP channels induced by HG.Pretreatment of the cells with 100 μmol/L mito-chondrial KATP channel opener diazoxide, 50μmol/L non-selective KATP channel opener pinacidil or NaHS obviously inhibi-ted HG-induced injuries, leading to an increase in the cell viability, and decreases in the number of apoptotic cells and the MMP loss.Pretreatment with 100μmol/L mitochondrial KATP channel antagonist 5-hydroxydecanoic acid or 1 mmol/L non-selective KATP channel antagonist glibenclamide attenuated the above cardioprotective effects of NaHS.CONCLUSION:KATP channels mediate the inhibitory effect of H2 S on HG-induced cardiac injury.

Objective To explore whether the phosphorylation of NF-κB P65 subunit is involved in the cytotoxicity to and inflammation in an immortal human keratinocyte cell line HaCaT during cobalt chloride (CoCl2-induced chemical hypoxia. Methods HaCaT cells were treated with CoCl2 of 2 mmol/L to set up a chemical hypoxia-induced cell model of injury. Then, RNA interference was used to down-regulate the expression of P65 in CoCl2-induced HaCaT cells. After additional culture, cell viability was tested by cell counting kit8 (CCK-8), the levels of interleukin 6 (IL-6) and interleukin 8 (IL-8) were detected by ELISA kits, phosphorylated and total P65 protein was measured by Western blot. Results The exposure of HaCaT cells to 2 mmol/L CoCl2 for 0 to 4 hours enhanced the phosphorylation of P65, which began at 0.5 hour, peaked at 1.5 hours, and restored to the normal level at 4 hours, and the level of P65 phosphorylation was about 6.6 times that in the untreated control group. The CoCl2 of 2 mmol/L decreased the cell viability of HaCaT cells in a time dependent manner, and a significant difference was observed in the viability of HaCaT cells between CoCl2-treated and untreated HaCaT cells at 2, 4, and 6 hours (P ＜ 0.05, 0.01, 0.01 ). The release of IL-6 and IL-8 from HaCaT cells was also promoted by CoCl2 treatment. The knockdown of P65 expression with siRNA markedly suppressed the CoCl2-induced cytotoxicity to and increase in the release of IL-6 and IL-8 from HaCaT cells,despite of an increment in cell viability by about 11%. Conclusion The phosphorylated P65 subunit mediates CoCl2-induced cytotoxicity and inflammatory injury to HaCaT cells.
