Pancreatic cancer is a common disease with a poor prognosis. Despite recent advance in the field of diagnos-tic technique, surgical resection and adjuvant therapy for pan-creatic cancer, the overall 5-year survival rate is still less than 5%. This is due to its aggressive growth behavior, early local invasion and metastasis, and resistance to chemotherapy and radiation therapy. Surgical treatment is still regard as the only chance for curing pancreatic cancer. Many new strategies in the surgical treatment of pancreatic cancer, including extended lymphadeneetomy, vascular resection, the use of laparoscopy, surgery for metastastic or recurrent disease, and neoadjuvant therapy, are currently under debate. In this review, we discuss the current status of surgical treatment for pancreatic cancer, and highlight the controversies and focus.

Nanobodies are derived from the variable domain of the heavy-chain antibodies (HCAbs) that occur naturally in the serum of Camelidae. They are the smallest antibody fragments capable to bind antigens. With the characteristics of their increased solubility, increased domain stabilities, nanomolar affinities, easy crossing the blood-brain barrier, easy generation, engineering, optimization and tailoring, easy humanization, nanobodies have extensive application prospects in diagnosis and detection. Although nanobody has demonstrated tremendous success, a number of practical challenges limit its broader applications in disease diagnosis and detection, including construction of a phage library and selection of nanobody fragments with high affinity and immunogold labeling technique. Here, we review several recent findings on the use of nanobodies in molecular diagnostics and suggest some practical strategies in resolving the current challenges in this attractive research area, particularly to optimize the affinity, solubility, humanization of nanobodies.

OBJECTIVETo investigate the effects of micro(mi) RNA-195 on high-glucose induced neonatal cardiomyocyte hypertrophy and to explore the related mechanism.

METHODSThe potential target gene of miRNA-195 (Smad7) was predicted by TargetScan5. 1 software. Cardiomyocytes were isolated from neonatal SD rats and cells were then randomly divided into three groups: cells treated by culture medium containing 5 mmol/L glucose (control group) , by culture medium containing 25 mmol/L glucose (high glucose group) and treated by culture medium containing 25 mmol/L glucose and miRNA-195 inhibitor transfection (miRNA-195 inhibitor group). After 24, 48, or 72 h of in vitro culture, the morphology of cardiomyocytes was examined under phase contrast microscope. Micrographs were captured and the cell surface was calculated. The mRNA expressions of miRNA-195 and myosin heavy chain β (β-MHC), a biomarker for cardiomyocyte hypertrophy, in cardiomyocytes were detected by RT-PCR. The protein expression of Smad7 was determined by Western blot. The concentration of transforming growth factor-β1 (TGF-β1) in the supernatant of culture medium was measured by ELISA.

RESULTSCross-sectional area of cardiomyocytes, expression of miRNA-195 and β-MHC and secretion of TGF-β1 were significantly increased in high glucose-treated cells (P < 0.05 vs. normal control). The protein expression of Smad7 was significantly downregulated in cells exposed to high glucose for 48 h (P < 0.05 vs. normal control). Downregulation of miRNA-195 partly reversed the high glucose-induced effects. The expression of Smad7 was negatively correlated with miRNA-195 in high glucose control group (correlation coefficient: -0.945, P < 0.05).

CONCLUSIONOur results demonstrate that Smad7 could be the target gene of miRNA-195. miRNA-195 might play a crucial role in the development and progression of diabetic cardiomyopathy possibly through downregulating the expression of Smad7 and modulating TGF-β/Smad pathways.

OBJECTIVE:To explore the effects and safety of Hedan tablets on the levels of blood lipid,inflammatory factors and oxidative stress in coronary heart disease(CHD)patients with type 2 diabetes mellitus(DM2). METHODS:A total of 118 pa-tients diagnosed as CHD with DM2 were collected from our hospital during Jul. 2013-Nov. 2015,and then divided into observation group(63 cases)and control group(55 cases)according to random number table. Control group received conventional treatment such as controlling blood glucose,regulating blood lipid,vasodilator,anticoagulant. Observation group additionally received He-dan tablets 1.46 g before meal,tid,on the basis of control group. Both groups received treatment for 6 months. The levels of blood lipid (TC,TG,LDL-C,HDL-C),serum inflammatory factors (TNF-α ,IL-10,IL-6,hs-CRP) and oxidative stress indexes (MDA,SOD,NO)before and after treatment as well as the occurrence of ADR were compared in 2 groups. RESULTS:Before treatment,there was no statistical significance in levels of blood lipid,serum inflammatory factors or oxidative stress indexes be-tween 2 groups(P>0.05). After treatment,the serum levels of TC,TG,LDL-C,TNF-α,IL-6,hs-CRP and MDA in 2 groups were decreased significantly,while those of IL-10,SOD and NO were increased significantly;the observation group was signifi-cantly better than the control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Hedan tablets can effectively improve the level of blood lipid,reduce the lev-el of inflammatory factors,relieve inflammatory injury,reduce the level of oxygen free radical,strengthen antioxidant capacity and lighten oxidative stress injury with good safety.
