Objective:To investigate the effects of Yukuiqing (YKQ) on the expression of connective tissue growth factor (CTGF) in cultured human renal mesangial cells (HRMC) incubated with AGEs. Methods:The HRMCs were incubated with AGEs (200 ?g/mL) and 1.25% YKQ which was prepared by Chinese herbal medicine serum pharmacological approach for 0,8,16,24,48 and 72h or different concentrations (0.313%,0.625% and 1.25%) of YKQ for 48h,respectively,which were incubated with DMEM and rat serum (RS) as the control. CTGF mRNA and protein were detected by reverse transcription polymerase chain reaction (RT-PCR) and Western Blotting respectively. Results:In Yukuiqing group,the expression of CTGF mRNA and protein decreased significantly compared with control groups (P

0.05),but the decrease of 2-hour postprandial blood glucose level and the increase of ISI in group A were superior to those in group B (P0.05).For the therapeutic effect,11 patients were cured,24 markedly effective,22 effective,13 ineffective and the total effective rate was 81.43% in group A;5 patients were cured,6 markedly effective,11 effective,13 ineffective and the total effective rate was 62.86% in group B.No obvious toxic and side effects were observed in the two groups during the treatment.【Conclusion】Yang-warming and spleen-strengthening therapy combined with antihyperglycemic drugs exerts a better effect on the treatment of insulin resistance in type 2 diabetes.

Objective To investigate the relationship between rapists and related allele genes based on the analysis of 15 short tandem repeats (STRs) loci genetic polymorphism. Methods The method of Genome-wide scan was being used. Buccal swab samples of 129 rapists and 156 random populations were collected and PCR compound amplification was carried out with the aid of AmpFISTR Identifiler system. Then the products were subjected to electrophoresis and gene detection with AB13100 type gene analysis system so as to calculate and compare the alleles of 15 STRs gene frequency in the two groups. Results All the 15 STRs loci allele gene frequency in rapists and random population was found to coincide with Hardy-Weinberg law(P>0. 05). Allele 28 of D21S11 (rapists: 1.55% ,control group:5. 13%) ,allele22 of FGA(rapists:24.03% ,control group:16.99%),allele23 of FGA(rapists: 17.05% ,control group:26.28%) ,allele 10 of TH01(rapists:1.16% ,control group:4.17%) ,allele 8 of TPOX(rapists:55.77% ,control group:63.77%),allele 12 of TPOX(rapists:4.26% ,control group: 1.28%) were different between the two groups (P< 0.05) .while it is no differ significantly in other STRs loci allele gene(P >0.05). Conclusion Allele 28 of D21 S11,allele 22 and 23 of FGA, allele 10 of TH01, allele 8 and 12 of TPOX may be associated with the violent crime of rape. It is suggested that there are existing sensitive or resistance genes about the violent crime of rape in chromosome 2,4,11,21.

Objective To verify the antiviral effects of Siji Kangbingdu mixture (SJKBDM) against coxsackievirus A16 (CoxA16).Methods Vero cells and 5-day-old suckling mice, injected with 75/50 and 1×106 TCID50 CoxA16, were used as evaluation models.The preventive influences of SJKBDM against CoxA16 in Vero cells were assessed in the models.The effects of SJKBDM on the mortality, survival time, change rate of body weight, and clinical symptom scores of suckling mice were observed.Results ①The half maximal inhibitory concentration of SJKBDM on Vero cells was 9.59 mg·mL-1.②Toxic effects were not observed from 32.3 g·kg-1 single dose or continuous intraperitoneal injectin of SJKBDM in suckling BALB/c mice.③The SJKBDM had significant inhibitory effect against CoxA16 virus.Doses higher than 1.22 mg·mL-1 could significantly improve the Vero cell survival rate, and the SJKBDM inhibition of 75/50 TCID50 CoxA16 induced pathological changes in Vero cells.④The SJKBDM significantly improved clinical symptoms of mice with CoxA16 viral infection, especially with crude drug doses of higher than 1.62 g·kg-1.The survival rate and other indicators were comparable or slightly higher compared with ribavirin, and the clinical score was higher than that of ribavirin.Conclusion The SJKBDM has significant inhibitory effect on CoxA16 cell proliferation, significantly decreases death rate, and improves clinical symptoms of mice infected with CoxA16 virus.

Purpose To investigate the application value in diagnosis of pleural effusion by cell block combined with immunohisto-chemistry. Methods 60 cases of pleural effusion were collected, and paraffin-embedded cell block was prepared and immunohisto-chemistry was used to detect the expression of CK7, TTF-1, E-cadherin, CEA and Calretinin. Results By use of cell block combined with immunohistochemistry, malignant detected rate was higher than that of the conventional centrifugal smear. There was statistical significance in the expression of CK7, TTF-1, E-cadherin, CEA and Calretinin between pleural effusion lung adenocarcinoma and reac-tive hyperplasia mesothelial cells (P<0. 05). CK7, TTF-1, E-cadherin and CEA were highly expressed in pleural effusion of lung ad-enocarcinoma cell. Calretinin was highly expressed in hyperplastic mesothelial cells. Conclusion Cell block and immunohistochemi-cal technique combination in the differential diagnosis of difficult pleural effusion has important clinical significance. It is worthy of popularization and further clinical application.

Objective　To investigate genes involved in cancer metastasis, mRNA differential display was used to compare the levels of gene expression in two cell sublines derived from human giant cell carcinoma of lung (PG) which had different metastatic potentials. Methods　Using in vivo tumorigenicity and a spontaneous metastasis assay in nude mice, two sublines (BE1, LH7) from human giant cell carcinoma of lung (PG) with different metastatic potentials were isolated and characterized. mRNA differential display was used to compare the levels of gene expression between them and the obtained results were confirmed by Northern hybridization. Results　One differentially expressed band was nearly identical (99% homology) to Ras-GTPase-Activating protein SH3 domain binding protein (G3BP). G3BP displayed a strong expression in LH7 (non-metastatic in recipient nude mice) and a very weak expression in BE1 (100% metastatic frequency). The same different expression level of G3BP was detected in Northern hybridization with another panel of cell sublines with different metastatic potentials (established in our lab) derived from human prostate carcinoma cell line PC-3M. Conclusion　Our results indicate that G3BP was implicated in cancer metastasis because of its differential expressions in the two panels of cell sublines with different metastatic potentials.

Radiographic detection of pulmonary nodules based on three-dimensional Hessian matrix is highly sensitive but frequently produces false positive results in areas where blood vessels intersect. We propose a novel approach to pulmonary nodule detection using Hessian matrix-based adaptive window structure analysis, in which the structure coefficients is used to differentiate a voxel that belongs to a nodule or vascular structures, followed by construction of the 3D adaptive window to analyze the local structure characteristics; the nodules were then detected using the discrimination function. The experimental results on pulmonary CT images from 17 patients showed a 100% detection sensitivity for nodules of varying sizes and types, with also significantly reduced false positive results generated by the vessel junctions. This approach provides valuable assistance to follow-up positioning and segmentation of the pulmonary nodules.

Regular physical activity (PA) is a key element in the prevention and management of type 2 diabetes mellitus (T2DM). Participation in regular PA improves blood glucose control and can prevent or delay T2DM and its complications, along with positively affecting lipids, blood pressure, cardiovascular events, mortality, and quality of life. However, most people with T2DM are not active and show poor adherence. This paper reviews the possible barriers to PA and strategies to improve the adherence to PA. Based on the currently available literature, it is concluded that self-efficacy and social support from family, friends, and health care providers play the important role in adoption and maintenance of regular PA. Here we also highlight some new modern and innovative interventions that facilitate exercise participation and improve the adherence.
