Ojective To investigate the relationship between the serum adiponectin concentration and insulin resistance in patients with obesity and diabetic patients. Methods Fasting serum adiponectin concentration was measured by RIA in 19 normal subjects, 23 obese subjects, 31 diabetic patients without obesity and 26 diabetic patients with obesity. Results There was no significant difference in serum adiponectin concentration between nomal and obese subjects, and between type 2 diabetics without obesity and type 2 diabetics with obesity . The serum adiponectin concentrations was significantly higher in type 2 diabetics without or with obesity than that in nomal and obese subjects. There was significant difference in serum adiponectin concentration between female and male subjects. Body mass index (BMI), waist circumference(WC), waist-hip ratio (WHR), body fat percentage (BF%), fasting plasma glucose (FPG), insulin sensitivity index (ISI), triglyceride (TG) and high density lipoprotein-C (HDL-C) were significantly correlated with serum adiponectin concentration. A stepwise mulitiple linear regression analysis showed that HDL-C, FPG, WC, BF% entered the regression equation. Conclusion Serum adiponection level was associated with sex, obesity, type 2 diabetes mellitus and insulin resistance.

The effectiveness and safety of acupuncture for the treatment of supraventricular tachycardia were systematically reviewed. The randomized controlled trials (RCTs) regarding acupuncture for supraventricular tachycardia were searched in domestic and overseas databases, and the evaluation tool of bias risk in Cochrane Handbook 5.1.0 software was used to perform the evaluation of bias risk in literature, and RevMan 5.2 software was applied for statistics and Meta-analysis. Five RCTs involving 323 patients were included. The results showed that compared with the blank control group, the acupuncture reduced the heart rate by 18.8 times/min [95% CI (12.68, 24.92)]; the clinical effective rate in the acupuncture group was superior to that in the diltiazem group [OR= 3.11, 95% CI (1.50, 6.46)]; the difference of immediate effect between propafenone and acupuncture was not significant. No reports regarding adverse events was described in 5 RCTs. As was shown in the present evidence, acupuncture is safe and effective for the treatment of supraventricular tachycardia, but the level of evidence was low and the intensity of conclusion needed to be improved.

The event-related potential (ERP) is considered as one of the most effective methods to study and analyze objectively human mental activity based on nerve electrophysiology. At present, ERP is not only used in the study of lie detection, but also in the clinical medicine for the cognitive assessment on patients with cerebrovascular disease, dementia or traumatic brain injury and auxiliary diagnosis of mental illness. With the further development of ERP detection technology, it would have a wider application prospect in the field of forensic medicine.

Tumor brings great threat to human public health. In recent years, incidence rate and mortality of tumor were rapidly increased in the world. Anti-tumor therapies have undergone the development of cytotoxic therapy, targeted therapy, and immunotherapy. Among them, tumor immunotherapy is rapidly developed and becomes an important anti-tumor therapy in recent years, although it also brings some related side effects. Tumor microenvironment (TME) is composed of immune cells, vascular vessels, fibroblasts, the extracellular matrix, etc. TME significantly affects the efficacy of immunotherapy. Macrophages in the TME are named as tumor associated macrophages (TAMs). Recently, increasing studies have shown that TAMs play an important role in the regulation of tumor immunity, especially in tumor immune surveillance and immune escape. Currently, more and more anti-tumor immunotherapy strategies targeting TAMs are at the development stage. Based on the important role of TAMs in the TME and their potential as therapeutic targets in tumor immunotherapy, we first reviewed the subtypes and functions of TAMs, as well as the roles of TAMs in tumors. Furthermore, we summarized the research progress on anti-tumor strategies targeting TAMs and the current status of drug targeting TAMs. The current review will provide new ideas and novel insights for tumor immunotherapy.

Sodium-glucose co-transporters are a family of glucose transporter found in the intestinal mucosa of the small intestine (SGLT-2) and the proximal tubule of the nephron (SGLT-1 and SGLT-2). They contribute to renal glucose reabsorption and most of renal glucose (about 90%) is reabsorbed by SGLT-2 located in the proximal renal tubule. Selectively inhibiting activity of SGLT-2 is an innovative therapeutic strategy for treatment of type 2 diabetes by enhancing urinary glucose excretion from the body. Therefore SGLT-2 inhibitors are considered to be potential antidiabetic drugs with an unique mechanism. This review will highlight some recent advances and structure-activity relationships in the discovery and development of SGLT-2 inhibitors including O-glycoside, C-glycoside, C, O-spiro glycoside and non glycosides.

Objective To observe whether the expression of interferon-regulatory factor genes are re- lated to systemic lupus erythematosus (SLE).Methods The clinical data of 45 SLE patients and 37 normal controls were collected.Total RNA of peripheral blood was extracted and transcripted into cDNA.Sybr green dye based real-time quantitative PCR method was used to compare the expression (indicated as-??Ct value) of IRFI,IRF4,IRF8 in patients with SLE and those in the controls.Results The levels of IRF1,IRF4 and IRF8 mRNA were-3.90?0.19,-8.04?0.25 and 3.60?0.15 respectively in normal controls.In SLE patients, IRF4 mRNA expression was -8.82?0.18,higher than that in normal (P=0.011).But IRF8 mRNA expression was 3.09?0.13,lower than that in normal (P=0.012).Conclusion Abnormal IRF mRNA expression is found in the peripheral blood of SLE patients.IRFs may play roles in the pathogenesis of SLE by affecting the differen- tiation of Th cells.

Objective To report a case of deep mycosis caused by Rhizomucor chlamydosporus. Methods Medical history,histopathology and laboratory examination were investigated,and fungal identifi- cation by microscopy and culture as well in the patient.Results The patient,a 41-year-old male,initially presented with mild-tender and progressively aggravating masses on the right glutea,both groins,and back of the head of pancreas.Later,ulcer,necrosis,and black crusts developed at the primary lesions accompanied with nausea,vomitting and dysfunction of liver.Pathological examination revealed a chronic granuloma- tous inflammation in the dermis and subcutaneous tissue;and branching,nonseptate and broad hyphae in multinuclear giant cells,tissue spaces and blood vessel lumens,and,few PAS-positive septate hyphae as well as basophilic chlamydospores located in multinuclear giant cells.The isolate was identified as R. chlamydosporus.Conclusions The case of deep mycosis caused by R.chlamydosporus began with invasive granuloma,followed by necrotic ulcer,with condition aggravating rapidly,and the patient finally died of se- rious cachexia.

BACKGROUNDAtrial fibrillation (AF) is the most common supraventricular arrhythmia in clinical practice. Chronic atrial fibrillation (CAF) is associated with ionic remodeling. However, little is known about the activity of ATP-sensitive potassium current (IK, ATP) during CAF. So we studied the changes of IK, ATP density and allosteric modulation of ATP-sensitivity by intracellular pH during CAF.

METHODSMyocardium samples were obtained from the right auricular appendage of patients with rheumatic heart disease complicated with valvular disease in sinus rhythm (SR) or CAF. There were 14 patients in SR group and 9 patients in CAF group. Single atrial cells were isolated using an enzyme dispersion technique. IK, ATP was recorded using the whole-cell and inside-out configuration of voltage-clamp techniques. In whole-cell model, myocytes of SR and CAF groups were perfused with simulated ischemic solution to elicit IK, ATP. In inside-out configuration, the internal patch membranes were exposed to different ATP concentrations in pH 7.4 and 6.8.

RESULTSUnder simulated ischemia, IK, ATP current density of CAF group was significantly higher than in SR group [(83.5 +/- 10.8) vs. (58.7 +/- 8.4) pA/pF, P < 0.01]. IK, ATP of the two groups showed ATP concentration-dependent inhibition. The ATP concentration for 50% current inhibition (IC50) for the SR group was significantly different in pH 7.4 and pH 6.8 (24 vs. 74 micromol/L, P < 0.01). The IC50 did not change significantly in CAF group when the pH decreased from 7.4 to 6.8.

CONCLUSIONSDuring CAF, IK, ATP current density was increased and its allosteric modulation of ATP-sensitivity by intracellular pH was diminished.
