Objective To explore the significance and correlation between MCP-1 and cardiovascular complication of diabetes. Methods 65 patients with diabetes and 64 patents with IGT and 60 healthy persons as control group are chosen from a population of 1231residents at Jiangnan community in Guangzhou city. Ultrasonic inspection of carotid artery was applied to the intimae media thickness (IMT),and the levels of-MCP-1 were detected by Elisa. Result There was significant difference in the levels of MCP-1 among the normal control group, IGT group and DM group (P=0.000).The levels of MCP-1 in IGT complicated with AS patients were significantly higher than that in IGT alone patients. The levels of MCP-1 in DM complicated with AS patients were significantly higher than that in DM alone patients. The levels of MCP-1 were positively correlated with IMT in these patients. A forward LR Logistic regression analysis showed that IMT was a dependent variable, gender, MCP-1 and age are independently correlated with IMT. Conclusion MCP-1 is correlated with diabetes and its cardiovascular complication and it may be served as the target of therapy.

In this study, the rat type 2 diabetes mellitus (T2DM) model was established through tail vein injection with low dose of streptozotocin (STZ) and high fat diet for 8 weeks, and then treated with Jiaotai Pill. The oral glucose tolerance test (OGTT), fasting serum insulin (FINS), free fatty acid(FFA) levels and blood lipid were assayed. HOMA-IR was calculated. Pancreatic pathology was performed. And pancreatic triglyceride (TG) content was examined by the lipid extraction method. Pancreatic islet cell apoptosis were detected by terminal dexynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL). According to the results, the model group showed abnormal OGTT, increased FINS, HOMA-IR, FFA, lipid disorder, obvious fat accumulation and significantly increased TG content in pancreatic tissues, and enhanced pancreatic islet cell apoptosis. Compared with the model group, the Jiaotai Pill group displayed improved OGTT, reduced FINS, HOMA-IR, FFA, recovered lipid disorder, decreased fat accumulation and significantly declined TG content in pancreatic tissues, and lowered pancreatic islet cell apoptosis. In summary, Jiaotai pill could effectively treat type 2 diabetes in rats. Its mechanism may be related to the reduction in pancreatic fat accumulation and islet cell apoptosis.

OBJECTIVEThe purpose of this study was to evaluate the maximum binding (Bmax) and affinity Kd value changes of acetylcholine receptor (n-AchR) on rat's superficial masseter muscles after functional mandibular advancement.

METHODSForty 5-week-old male SD rats were randomly divided into experimental and control groups. The mimic functional appliances were only used in experimental groups, and the rats of two groups were killed after 1, 3, 7, 14 days. Radio-ligand binding assay (RBA) was applied to determine the Bmax and Kd value of n-AchR on the superficial masseter muscles.

RESULTSThe Bmax of n-AchR in experimental groups was higher than that in the control groups at all time points, and the differences had statistical significance. The Kd value of n-AchR was higher in experimental group than that in control groups in 1, 3, 7 days, while Kd value in experimental group of n-AchR was lower than that in control groups in 14 days. The differences had statistical significance in 7 and 14 days, but the differences had no statistical significance in 1 and 3 days.

CONCLUSIONThe functional orthopedics can increase the Bmax and affinity of n-AchR on rapid growing rat's superficial masseter muscles.

AIMTo identify "Shegan" [Belamcanda chinensis (L.) DC.] and relative medicinal plants of Iris including Iris tectorum Maxim., I. dichotoma Pall., I. germanica L. and I. japonica Thunb. by ribulose 1,5-bisphosphate carboxylase Large Gene (rbcL) sequence analysis.

METHODSGeneral DNA was isolated from the fresh leaves of Belamcanda chinensis and 4 Iris spp. by CTAB. A pair of primers was designed to amplify the rbcL gene and PCR Preps DNA kit was used to purify the PCR products. The rbcL sequences were determined by ABI (Applied Biosystems Inco.) Prism 310 Genetic Analyzer.

RESULTSA fragment of about 750 bp of rbcL gene from Belamcanda chinensis and 4 Iris spp. were amplified and sequenced. The rbcL sequences of Iris tectorum, I. dichotoma Pall. and I. japonica were reported for the first time. The rbcL sequences of 5 species of Iridaceae were aligned and analyzed using Clustal (Version 8.0) and MEGA (Version 2.0.) programs. The nucleotide number of difference is from 1.000 to 20.000. The tranversions is from 0.000 to 9.000 and the transitions is from 0.000 to 14.000. Phylogenetic tree based on rbcL partial sequence data indicated that the eleven samples of 5 species clustered separately.

CONCLUSIONThe sequence variation of rbcL can be used to identify Belamcanda chinensis and 4 species of relative medicinal plants of Iris. The molecular phylogenetic tree accords with the classical taxonomy.

OBJECTIVETo explore the follow-up visit, outcome and auxiliary diagnosis method on the cases with indeterminate antibody level measured by Western blotting as well as the related biological factors.

METHODSThe cases with indeterminate result were followed up according to the National Guideline for Detection of HIV/AIDS (2009) and samples were collected for HIV antibody detection, p24 antigen and nucleic acid were detected as a supplementary diagnosis at the same time. The samples were also be detected for HBV, HCV, TP, HTLV-I/II, ANA, and AFP, and the results were compared to that of screened positive and confirmed negative cases.

RESULTSA total of 73 were followed up successfully and taken a second HIV test, 25 cases were tested positive and 48 were tested negative for HIV during the follow-up period. For the 25 HIV positive cases, the HIV seroconversion rate was 100.00% at any time point when the interval between the first and returning detection was longer than 1 week. The major Western blotting bands for the cases with indeterminate result were p24 and gp160 and it was different between HIV positive and negative cases in Western blotting band profiles. The consistency and sensitivity of nucleic acid detection were higher than 90.00%, and were higher than that of p24 antigen (69.09% (38/55) and 27.27% (6/22)) (χ(2)(consistency) = 6.875, χ(2)(sensitivity) = 18.893, P < 0.05). The positive rates of ANA and AFP of indeterminate cases excluded from HIV infection were 20.83% (10/28) and 6.25% (3/48) and higher than that of screened positive and confirmed negative cases (0.00%), the difference had statistic significance (χ(2)(ANA) = 19.430, χ(2)(AFP) = 5.520, P < 0.05).

CONCLUSIONIt is critical to get timely diagnosis for the indeterminate cases according to the new national guideline for detection of HIV/AIDS. Nucleic acid detection has higher application value as auxiliary diagnosis for HIV infection than p24 antigen. The increased levels of ANA and AFP may be the factors resulting in the nonspecific indeterminate results.
