Objective To explore the correlation of adipnectin with T2DM and its macrovascular complications. Methods The levels of serum adiponectin, plasma glucose, serum lipids, and fasting insulin were measured in normal subjects, type 2 diabetic patients and type 2 diabetic patients with macrovascular complications. Results (1) The serum adiponectin level was significantly lower in type 2 diabetic patients than in normal subjects, and was the lowest in type 2 diabetic patients with macrovascular complications. (2) Serum adiponetin level was negatively correlated with BMI,HOMA-IR, HbA_1c,TG and fasting insulin level. Conclusions The results suggest that lower serum adiponectin level may be related to macrovascular complications in type 2 diabetic patients.

The majority of complications due to orthotopic liver transplantation (OLT)need interventional treatment. For arterial and venous complications after OLT, we have established clear and definite interventional therapeutic mode. However, it has been the difficult point as well as the weak point for interventional radiologists to treat the biliary complications. With the technical improvement and deep-going understanding, a part of biliary complications of OLT can be relieved or even finally be cured with percutaneous biliary drainage(PTBD) and endoscopic nasobiliary drainage(ENBD). For some patients, PTBD and ENBD seem to be the main palliative therapeutic means, which might accompany the patients for a lifetime. Now, it is an urgent demand to formulate the clinical therapeutic guidelines for the treatment of biliary complications after OLT.

Objective To measure the changes of portal venous pressure before and after APS by percutanous portal vein catheterization and to quantitatively analyse the correlation between portal pressure and portal hypertension.Methods All the 18 central arterioportal shunts (APS) patients with hepatocellular carcinoma (HCC) were treated with embolization of APS and TACE, and the pressure of portal vein was measured by percutaneous portal vein catheterization pre- and post-embolization of APS. Color dopplar sonography and endoscopy were employed to investigate before and 2 weeks after embolization in all patients. Results The pressure of portal vein decreased significantly after embolization, and the decreased rate was 5.4%-33.3% with the mean rate 20.1%. After the embolization, the width of portal vein decreased and the blood flow velocity of portal vein increased significantly, P

Objective To understand the serum adiponectin levels in normal subjects and type 2 diabetes patients with macrovascular complications, to investigate the correlation between adipnectin and macrovascular complications in type 2 diabetes patients. Methods One hundred and two normal subjects, 116 type 2 diabetes patients and 123 type 2 diabetic patients with macrovascular complications were recruited in the current study. The serum adiponectin levels among three groups were compared, and the factors affecting the serum adiponectin were investigated. Results ①The serum adiponectin level was significantly lower in type 2 diabetic patients (8. 62 ± 2. 97) mg/L than that in normal subjects (10. 03 ± 4.41) mg/L, and was the lowest in type 2 diabetic patients with macrovascular complications(6. 17 ± 2. 55) mg/L(P < 0.05). ②Serum adiponetin level was negatively correlated with BMI,WHR,HOMA-IR,fasting insulin level, HbAlC and TG(r = -0.492, -0. 581, -0. 813, -0. 754, -0.619, -0.387, P<0.05). ③In a general multivariate regression, HOMA-IR fasting insulin and HbAlc.were negatively correlated with serum adipnectin level (r = - 0. 828, - 0. 769, - 0. 631, P < 0. 01). Conclusions The serum adiponectin level in type 2 diabetic patients is significantly decreased and even more in type 2 diabetic patients with macrovascular complications. These results suggest that lower serum adiponectin level is related to macrovascular complications in type 2 diabetic patients and maybe plays an important role in atherosclerosis in type 2 diabetic patients.

We selected several platiniferous and non-platiniferous chemotherapy strategies of typical in the article to analyze patients with non-small cell lung cancer can tolerate non-platiniferous chemotherapy strategies, side effects are smaller than p]atiniferous chemotherapy strategies.

Atrial fibrillation (AF) is one of the most common and age-related persistent arrhythmias. With the increase of age, the prevalence of AF and the incidence of atrial fibrillation-related stroke are increased. Due to the decline of cognition and function of various organs, coupled with the increase of comorbities and complications, the types of drug use also are increased in elderly patients, and their anticoagulant therapy has become complex. New anticoagulant drugs increase the choice of treatment in elderly patients with AF. This article reviews the clinical characteristics, necessity, challenge and drug selection of anticoagulant therapy in elderly patients with non-valvular AF to provide information for rational anticoagulant therapy.

Objective To investigate the expression of metallothionein (MT) in 113 specimens of liver transplantation for patients with benign end-stage liver diseases and 10 normal liver specimens,and analyze their clinical significance and prognostic value.Method 113 specimens of liver transplantation for patients with benign end-stage liver diseases and 10 normal liver specimens were included in this study.MT in these specimens was detected by using immunohistochemistry.Cox regression model was used to analyze the multi-factors for the prognosis.Results MT levels were lower in specimens of liver transplantation for patients with benign end-stage liver diseases than in normal liver specimens.MT levels were higher in specimens of HCV-related cirrhosis than in those of autoimmune hepatic (AIH) cirrhosis,but there was no significant difference among all other groups.Conclusion MT expression level in AIH cirrhosis tissue is higher than in HCV-related cirrhosis tissue.MT is the independent influencing factor for survival following liver transplantation in patients with benign end-stage liver diseases.

AIM: To study the infiltration of polymorphonuclear neutrophils ( PMNs ) after conjunctival flap covering in alkali-burned cornea.
●METHODS: Rabbit cornea alkali-burned model was made, then 50 rabbits were randomly divided into the experimental group ( n=25 ) and the control group ( n=25 ) . At the same time the surgery of conjunctival flap covering was given to rabbits of the experimental group. The condition developing of alkali-burned cornea was observed by slit lamp biomicroscopy, and took photos in two groups. The infiltration of PMNs was identified by hematoxylin eosin ( HE) staining in different periods.
●RESULTS:The quantity of PMNs increased on the 3d, reached the lower level on 7d, shown a peak on the 14d, then decreased gradually. PMNs level of the experimental group was significantly lower than that in the control group, and the difference of 3, 14 and 21d was significant (P<0. 05).
●CONCLUSION: During the wound healing process, alkali - burned cornea has close relation with the infiltration of PMNs. The treatment of conjunctival flap covering for the severe alkali-burned cornea was found to have good effect.

Quorum sensing systems of pathogens are central regulators for the expression of virulence factors. Increasing evidence implies that targeting the quorum sensing system of many pathogenic bacteria is a promising therapeutic approach to control infections. In this work,we isolated 47 strains of actinomycetes from the mud sample of Jiaozhou Bay. Quorum sensing inhibitory activity was monitored by Chromobacterium violaceum CV026. As a result,the culture broth extract of actinomycetes WA-7 was found to have significant quorum sensing inhibitory activity. This strain was assigned to the genus Streptomyces based on its 16S rDNA sequence. Further investigation revealed that the extract could inhibit the quorum sensing-controlled violacein and proteases production of C. violaceum in a concentration-dependent manner.
