OBJECTIVETo investigate the effect of Jiangtang Yishen Recipe (JTYSR) on high insulin induced cell proliferation of human glomerular mesangial cells (HMCs) and the expression of insulin receptor substrate 1 (IRS-1) and phosphatidylinositol-3-kinase (PI-3K).

METHODSHMCs were divided into 4 groups, i.e., the negative control group, the high insulin model group, the JTYSR group, and the LY294002 group. The concentration of insulin, JTYSR, and LY294002 was respectively confirmed by pre-experiment. Different culture solution was respectively added for different groups. RPMI1640 culture solution was added for HMCs in the negative control group, while HMCs in the rest 3 groups were cultured by 100 nmol/L insulin for 24 h. Meanwhile, HMCs from the JTYSR group and the LY294002 group were exposed to 125 mg/L JTYSR and 80 micromol/L LY294002 respectively for further 48 h. The proliferation of HMCs was detected by MTT and flow cytometry. The protein expression of IRS-1 and PI-3K in HMC was detected by immunohistochemical assay and Western blot. Results The proliferation of HMCs induced by high insulin could be significantly lowered, and the protein expression of IRS-1 and PI-3K could be down-regulated in the JTYSR group and the LY294002 group (P <0.01). Compared with the LY294002 group, the protein expression of IRS-1 and PI-3K could be slightly down-regulated in the JTYSR group (P <0.05).

CONCLUSIONJTYSR could lower high insulin induced proliferation of HMCs, and its mechanism might be related to insulin signaling pathway.

Background and Objective:The gross tumor volume (GTV) obviously reduces after induction chemotherapy (IC) for primary Iocoregionally advanced nasopharyngeal carcinoma (NPC). This study was to investigate the impact of changing gross tumor volume delineation on the dose distribution and clinical treatment outcome after IC. Methods: From January 2008 to April 2009, 24 patients with Stage Ⅲ-Ⅳb primary locoregionally advanced NPC were treated with TPF regimen IC followed by intensitymodulated radiotherapy (IMRT) with concurrent chemotherapy The primary GTVs were delineated into two parts: the post-IC primary GTV (GTVpost-IC-NP),and the region of pre-IC primary GTV minus GTVpost-IC-NP (GTVprepost-IC-NP). The dose distributions of two plans with GTVpost-IC-NP or pre-IC primary GTV were assessed by analyzing ten cases. The clinical treatment outcome and toxicity of all patients were observed. Results:The post-IC GTV was significantly smaller than the pre-IC GTV(primary GTV 25.5 cm~3 vs.51.1 cm~3,P=0.001;lymph nodes GTV 9.1 cm~3 vs. 31.4 cm~3, P=0.035;primary+lymph nodes GTV 33.2 cm~3 vs. 82.6 cm~3, P=0.004), the overall GTV with an average shrinkage of 61%. The high dose region was also smaller after IC(volumes covered by 64.4 Gy were 422.9 cm~3 vs.457.9cm~3, P=0.003; 274.2 cm~3 vs.334.5 cm~3 by 68 Gy, P=0.041). The complete response rate was 38% after IC,and 100% three month after radiotherapy.The toxicity of following IMRT with concurrent chemotherapy was similar to that of IMRT with concurrent chemotherapy alone. With median follow-up of 9 months, the locoregionally control rate was 100% and only one patient presented metastasis 15 months after treatment. Gonclusions: TPF regimen IC could significantly reduce tumor volume. The following IMRT with GTVpost-IC-NP plan reduced the high dose region,which didn't add toxicity while had excellent short-term treatment outcome.

OBJECTIVETo study the relationship between the serum levels of adipocyte fatty acid-binding protein (A-FABP) level and type 2 diabetes mellitus in a community population.

METHODSA total of 255 residents (aged 45-85 years) were randomly selected from 4 communities in Guangzhou to examine the fasting plasma glucose (FPG), 2-hour postprandial blood glucose (2hPG), glycosylated hemoglobin (HbA1c), body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR), blood pressure (BP), triglyceride (TG), cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C). The insulin resistance index (HOMA-IR) was calculated and enzyme-linked immunosorbent assay (ELISA) was used to determine serum A-FABP and fasting insulin (FINs) levels. The cases were divided into 3 groups according to blood glucose level, namely the normal group (group A, n=90), impaired glucose tolerance group (group B, n=85), and diabetic group (group C, n=80), and the A-FABP levels were compared between them.

RESULTSCompared with group A, the subjects in groups B and C showed significantly increased FPG, 2hPGh, HbA1C, HOMA-IR, systolic blood pressure (SBP), and waist circumference (P=0.000) as well as FINs, WHR, diastolic blood pressure (DBP) , TG, and HDL-C (P=0.038, 0.047, 0.01, and 0.046, respectively). Compared with group B, group C showed significantly higher FPG, 2hPG, HbA1c, TG, and SBP (P=0.00), with also higher levels of FINs, BMI, WC, DBP, and HDL-C (P=0.012, 0.006, 0.03, 0.019, and 0.029, respectively). A-FABP increased significantly in the order of group A, B, and C (P=0.00), and this result was not affected by the differences in age between the 3 groups (P>0.05). A-FABP level was positively correlated to FPB, 2hPG, FINS, WHR, BMI, WC, SBP, and HOMA-IR, but inversely to TG and HDL-C (P=0.00).

CONCLUSIONElevated serum A-FABP is closely related to glucose metabolism disorder, and A-FABP may serve as a useful marker for the occurrence and development of type 2 diabetes in the community population.

microRNAs (miRNAs) are a class of non-coding RNAs that function as endogenous triggers of the RNA interference pathway. Studies have shown that thousands of human protein-coding genes are regulated by miRNAs, indicating that miRNAs are master regulators of many important biological processes, such as cancer development. miRNAs frequently have deregulated expression in many types of human cancers, and play critical roles in tumorigenesis, which functions either as tumor suppressors or as oncogenes. Recent studies have shown that miRNAs are highly related with cancer progression, including initiating, growth, apoptosis, invasion, and metastasis. Furthermore, miRNAs are shown to be responsible for the cancer-related inflammation, anti-cancer drug resistance, and regulation of cancer stem cells. Therefore, miRNAs have generated great interest as a novel strategy in cancer diagnosis and therapy. Here we review the versatile roles of miRNAs in cancers and their potential applications for diagnosis, prognosis, and treatment as biomarkers.

OBJECTIVETo analyze effects of different thread helix angles and densities on the primary stability of immediately loaded implants using the three-dimensional finite element model analysis.

METHODSFive models of three-dimensional finite element (0.8 mm, 1.6 mm, 2.4 mm, double-threaded, and triple-threaded) were created using the commercial codes of Pro/E software, Hypermesh software, and ABAQUS software. In conditions of horizontal and vertical loading, the micro-motion of the finite element models with different thread helix angles and densities were computed with ABAQUS software.

RESULTSConcerning different thread helix angles, the micro-motion of single-threaded implant was the minimum and that of the triple-threaded was the maximum with vertical and horizontal loading. The micro-motion of doubled-threaded implant was the minimum compared with thread pitch 1.6 mm and the micro-motion of triple-threaded implant was the minimum compared with thread pitch 2.4 mm with vertical and horizontal loading.

CONCLUSIONSThe thread helix angle and density of implants can greatly affect the vertical interfacial micro-motion. With increasing thread pitchs, the resistance of implant to vertical load is weakened; with increasing thread helix angle, the resistance of implant to vertical load is weakened; with increasing thread density, the resistance of implant to the vertical load is weakened.
