OBJECTIVE:To investigate the effect of Cyslosorus acuminatus flavonone glycoside (CAF) on kidney epitheli-al-mesenchymal transition(EMT)in rats with diabetic kidney disease(DKD). METHODS:Rats were randomly divided into nor-mal group(normal saline),model group(normal saline),positive group [rosiglitazone,0.4 mg/(kg·d)],CAF high-dose and low-dose groups [12.5,25 mg/(kg·d)],10 in each group. Except for normal group,other groups were intraperitoneally injected strepto-zotocin(60 mg/kg)+high fat diet to induce DKD,and intragastrically administrated related medicines in 13-16 weeks. After the ex-perimental period,fasting blood glucose level and serum creatinine(Scr),blood urea nitrogen(BUN)contents of rats were detect-ed,collagen deposition and basement membrane thickening in kidney tissue were observed. Immunohistochemistry was used to de-tect α-smooth muscle actin(α-SMA),fibronectin,epithelial cadherin(E-cadherin)expressions in kidney tissue,and Western blot was used to determine the glycogen synthase kinase 3β(GSK-3β),phosphorylated GSK-3β(p-GSK-3β),β-catenin expressions in kidney tissue. RESULTS:Compared with normal group,fasting blood glucose level,Scr and BUN contents in model group were significantly increased (P<0.01);kidney tissue showed obvious collagen deposition and basement membrane thickening;theα-SMA,fibronectin,β-catenin expression levels and GSK-3β phosphorylation degree in kidney tissue were significantly increased (P<0.01),while E-cadherin expression levels was significantly decreased(P<0.01). Compared with model group,fasting blood glucose level,Scr and BUN contents in each administration group were significantly reduced(P<0.05 or P<0.01);collagen depo-sition and basement membrane thickening in kidney tissue were significantly improved;the α-SMA,fibronectin,and β-catenin ex-pression levels and GSK-3β phosphorylation degree in kidney tissue were significantly decreased (P<0.05 or P<0.01),while E-cadherin expression levels in positive group and CAF high-dose group were significantly increased(P<0.01). CONCLUSIONS:CAF can inhibit the kidney EMT of rats with DKD,the molecular mechanism may be associated with downregulating β-catenin ex-pression and inhibiting GSK-3βphosphorylation inactivation.

The new ultrasound device, automated breast ultrasound (ABUS), has the advantages of repeatable reading of standardized whole breast images, and can separate ultrasound scanning and diagnosis. ABUS is more suitable for breast ultrasound training. This study compared the breast ultrasound imaging training model with ABUS diagnosis practice as the core and the traditional breast ultrasound imaging training model with handhold ultrasound operation and diagnosis as the core, and found that the new training model with ABUS diagnosis practice as the core had a short training period. The diagnostic level of doctors have improved rapidly, and the new training model could efficiently train more technically qualified ultrasound doctors for breast disease.

Objective To study the protective effect of compound nitroglycerin gel on rats with skin ulcer wound and its action mechanism. Methods Skin ulcer modle of 54 rats was established.Then the rats were randomly divided into three groups (n=18 each), including model control group, Jin wan hong group, and compound nitroglycerin gel group. Wound healing process and healing time were recorded.At the day 7 and 14 after the model was established, the number of fibroblasts and new blood capillaries of granulation tissue from center of the wound were measured,and RT-PCR was used to detect mRNA expression levels of VEGF, Ang1 andHIF-1α. Results As compared with model control group [(24.17±5.91) days], healing time of skin in the compound nitroglycerin gel group was significantly shorter [(14.67±3.76) days, P<0.01].The numbers of fibroblasts (61.20±7.56) and new blood capillaries (9.35±1.43) were increased, and mRNA expression levels of VEGF (1.692±0.196), HIF-1α (1.527±0.174) and Ang1 (1.548±0.203) were remarkably up-regulated on 7th day (P<0.05 or P<0.01).While on 14th day, the numbers of fibroblasts (28.00±5.96) and new blood capillaries (4.20±1.30) were decreased and the mRNA expression levels of VEGF (1.156±0.123), HIF-1α(1.021±0.105) and Ang1 (1.034±0.134) were significantly down-regulated (P<0.05 or P<0.01) . Conclusion Compound nitroglycerin gel can treat skin ulcer wound via regulating the numbers of fibroblasts, new blood capillaries and VEGF/Ang1/HIF-1α signal transduction pathway.

Objective To compare and investigate the role of ultrasonography and X-ray examination in the assesment of peripheral joints in psoriatic arthritis (PsA).Methods One hundred and twenty-five groups joints of twenty-five patients with PsA underwent ultrasonography and X-ray examination,including knee joints,wrist joints,ankle joints,metacarpophalangeal joints and interphalangeal finger joints,metatarsophalangeal joints and interphalangeal toe joints.The results of the two examinations were analysed and compared.Results The numbers of patients with abnormal joints in knee joints,wrist joints,ankle joints,metacarpophalangeal/interphalangeal finger joints,and metatarsophalangeal/interphalangeal toe joints were 9,9,9,10,and 11,respectively.Ultrasonography found more abnormal joints than X-ray ( P ＜0.01 ).The cardinal ultrasonographic manifestations of PsA were synovitis (29),tendonitiS (16),and bone erosion (7).The cardinal X-ray manifestations of PsA were bone destruction (11 ),periarticular osteoporosis (5),periosteal reaction (3) and periarticular soft tissue swelling (4).Ultrasonography found more synovium and tendon abnormalities than X-ray (P ＜ 0.01 ),and X-ray found more bone abnormalities than ultrasonography ( P ＜0.01).Conclusions Ultrasonography has the ability of demonstrating early changes of peripheral joints in PsA.The combination of ultrasonography and X-ray can make the diagnosis of PsA more correct and comprehensive.

Objective To evaluate the value of contrast-enhanced ultrasound in superficial lymphadenopathy. Methods Ninty-four superficial enlarged lymph nodes were studied by 2-dimensional, color Doppler ultrasound, and contrast-enhanced ultrasound. Then the contrast-enhanced images were analyzed by Philips Q-LAB software. All the results were compared with pathological diagnosis. Results For the 94 superficial lymph nodes examined,44 were benign,33 were metastases and 17 were lymphomas. The sensitivity, specificity,and accuracy of contrast-enhanced images were 84% ,74% and 790//oo respectively. Contrast-enhanced ultrasound examination showed intense homogeneous enhancement in 39 of 44 benign lymph nodes; high or low homogeneous enhancement in 25 of 33 and 7 of 33 in metastases respectively;intense homogeneous, and scarce enhancement in 6 of 17 and 9 of 17 in lymphomas respectively. Time-intensity curves showed that compared with metastasis lymph nodes and lymphomas, benign lymph nodes had higher peak intensity and larger area under the curve (P<0.01). Conclusions The diagnosis accuracy was significant increased when contrast-enhanced ultrasound was test against conventional ultrasound. The character of contrast agent enhancement and Q-LAB time-intensity curves provide valuable diagnosis information for differential diagnosis of benign,metastasis lymph nodes and lymphomas.
