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.

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.

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.

0.05, but the duration of pain was different in group A and B, P

0.05). The most frequent side-effects were abdominal pain and fever. The degree and duration of abdominal pain were higher and longer in group B than those in group A, but the occurrance rate of fever was lower in group B. The occurrance rate of severe complications showed no significant differences for both groups. The increase of embolization degree may aggravate post-embolization side-effects and raise the incidence of complications. Conclusions PVA may be used as the embolic material of PSE with embolization degree ranging from 50% to 70% which may alleviate hypersplenism in patients with cirrhosis, relieve post-embolization syndrome and decrease the incidence of severe complications.

Objective To analyze the risk factors of hospital acquired pneumonia (HAP) caused by nonfermentative bacteria in ICU.Methods Using binary logistic regression analysis,we reviewed the related risk factors of hospital acquired pneumonia caused by nonfermentative bacteria from January,2002 to May,2006 in ICU of our hospital.Results Univariate regression ana- lysis identified 22 variables associated with HAP,including age,diabetes mellitus,malignant tumor,chronic obstructive pul- monary disease (COPD),smoking,Glasgow Coma Scale (GCS) score,Acute Physiology and Chronic Healthy EvaluationⅡ(APACHEⅡ) score.Multivariate regression analysis confirmed 6 high risk factors:aspiration,COPD,use of antacids,seda- tive agents,mechanical ventilation and tracheal intubation or tracheostomy.Conclusions Aspiration,COPD,use of antacids, sedative agents,mechanical ventilation,tracheal intubation or tracheostomy are high risk factors associated with HAP.

Objective To study the human brucellosis infection status and its epidemic feature during 2003-2006.Methods A total of 485 blood samples of serum underwent rose bengal plate test(RBPT)and serum agglutination test(SAT),which include 422 cases having a history of contacting with sheep/goats or cattle,22 suspected eases,and 41 cases having contacted with infected persons.All cases were diagnosed according serology test and epidemiologic survey.Results The positive rates of Serum antibodies(SAT titer)were 8.8%(12/137),12.7%(8/63),13.1%(22/171)and 16.2%(19/114),respectively,during 2003 to 2006 in Tangshan,in an increasing Rend and peaked in the second and the third seasons 77.0%(47/61).The mostly infected population were those who contacted with sheep/goats or cattle,accounting for 98.4%(60/61).Livestock farmers 86.9%(53/61),and veterinarians 8.2%(5/61)were mostly likely to be infected.Assay of serum antibodies is negative in the persons contacting with infected cases.Conclusions The prevalence of human brucellsis had presented a rising tendency in highly dangerous crowd of Tangshan.Contacting with infected livestock(such as sheep/goats or cattle),especially their aborted materials and placenta were mainly transmitted modes of human brucellsis.However,cases of person-to-person transmission has not been discovered in this study.

Nitrites play multiple characteristic functions in invasion and metastasis of hepatic cancer cells, but the exact mechanism is not yet known. Cancer cells can maintain the malignant characteristics via clearance of excess mitochondria by mitophagy. The purpose of this article was to determine the roles of nitrite, reactive oxygen species (ROS) and hypoxia inducing factor 1 alpha (HIF-1 α) in mitophagy of hepatic cancer cells. After exposure of human hepatocellular carcinoma SMMC-7721 cells to a serial concentrations of sodium nitrite for 24 h under normal oxygen, the maximal cell vitality was increased by 16 mg x (-1) sodium nitrite. In addition, the potentials of migration and invasion for SMMC-7721 cells were increased significantly at the same time. Furthermore, sodium nitrite exposure displayed an increase of stress fibers, lamellipodum and perinuclear mitochondrial distribution by cell staining with Actin-Tracker Green and Mito-Tracker Red, which was reversed by N-acetylcysteine (NAC, a reactive oxygen scavenger). DCFH-DA staining with fluorescent microscopy showed that the intracellular level of ROS concentration was increased by the sodium nitrite treatment. LC3 immunostaining and Western blot results showed that sodium nitrite enhanced cell autophagy flux. Under the transmission electron microscopy (TEM), more autolysosomes formed after sodium nitrite treatment and NAC could prevent autophagosome degradation. RT-PCR results indicated that the expression levels of COX I and COXIV mRNA were decreased significantly after sodium nitrite treatment. Meanwhile, laser scanning confocal microscopy showed that sodium nitrite significantly reduced mitochondrial mass detected by Mito-Tracker Green staining. The expression levels of HIF-1α, Beclin-1 and Bnip3 (mitophagy marker molecular) increased remarkably after sodium nitrite treatment, which were reversed by NAC. Our results demonstrated that sodium nitrite (16 mg x L(-1)) increased the potentials of invasion and migration of hepatic cancer SMMC-7721 cells through induction of ROS and HIF-1α mediated mitophagy.

An ultra-performance liquid chromatography-quadrupole/time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) combined with reference herb method was developed to rapidly screen commercial sulfur-fumigated ginseng. Sufur-fumigated ginseng reference herb was prepared using genuine ginseng by conventional procedure. Then the reference sulfur-fumigated ginseng sample was analyzed by UPLC-Q-TOF-MS/MS to identify characteristic marker components. 25-hydroxyl-Re sulfate with higher abundance was se- lected as marker compound from 8 characteristic components identified in sulfur-fumigated ginseng reference herb. The fragmentation of 25-hydroxyl-Re sulfate was extensively investigated, fragment ion m/z 879.44 with higher intensity was chosen as the characteristic ion of sulfur-fumigated ginseng. The response of ion m/z 879. 44 was improved by optimizing the MS conditions so that this ion could be used as the characteristic marker ion for screening purpose in ion extracting screening mode. The established approach was successfully applied to inspect 21 commercial ginseng samples collected from different cities in China It was found that the chemical profiles of 9 samples were similar to that of sulfur-fumigated ginseng reference herb, and the characteristic ion m/z 879. 44 of 25-hydroxyl-Re sulfate was also detected in these samples, suggesting that there were nearly 43% ginseng samples analyzed being sulfur-fumigated. This findng agreed well with the results of sulfur dioxide residues of these 21 commercial ginseng samples determined with the method documented in Chinese Pharmacopeia Compared with the method documented in Chinese Pharmacopeia, the proposed approach is more rapid and specific for screening sulfur-fumigated ginseng. SFDA of China should strengthen the enforcement to prohibit ginseng being sulfur-fumigated, so that ginseng and it preparations could be effectively and safely benefit to the health of human beings.
