Objective To observe the influence of short-term continuous subcutaneous insulin infusion(CSII)on ?-cell function in newly diagnosed type 2 diabetes(T2DM).Methods A total of 32 inpatients with newly diagnosed T2DM who had a 14-day course of CSII were randomly assigned to two groups of OGTT and arginine stimulating test(AST).Before and after 3 days and 14 days CSII treatments,OGTT and AST were performed respectively.The changes of the values of plasma glucose,HOMA-IR,HOMA-? and △C30/△G30,△C120/△G120 or arginine-induced acute C-peptide reaction(ACRARG)in two groups were compared.Results In OGTT,the values of plasma glucose and HOMA-IR were decreased,HOMA-? and △C120/△G120 were increased significantly after CSII therapy,both in day 3 and day 14;and △C30/△G30 were unchanged after 3 days but increased markedly after 14 days.However,in ACRARG,the above mentioned parameters almost remained unchanged after CSII treatment in 3 days or 14 days.Conclusions In newly diagnosed T2DM with elevated fasting glucose levels,intensive insulin therapy can partly improve ?-cell function showed by OGTT,not by AST.

Type 1 diabetes mellitus and autoimmune thyroid disorders are the most common combination of autoimmune polyendocrine syndrome type Ⅲ(APS Ⅲ). However, APS Ⅲ combined with myasthenia gravis is rare. We described a male patient with myasthenia gravis, type 1 diabetes mellitus, and Hashimoto thyroiditis, who was diagnosed as APS Ⅲ. The human leukocyte antigen (HLA)type was analyzed in this patient. We subsequently reviewed 11 cases of APS Ⅲ combined with myasthenia gravis. This review revealed that HLA-DR9/DQ9 might be a specific HLA subtype associated with APS Ⅲ and complicated with myasthenia gravis .

To propose the new concept of multidimensional omics, and define that the multidimensional omics is a proper method for studying the material base and mechanism of traditional Chinese medicine (TCM) compounds. Zhuanggu Zhitong capsule was taken for example to study its effect against experimental postmenopausal osteoporosis. From the perspective of chemi-omics, genomics and proteomics of TCM, it systematically interpreted the efficacious materials and mechanisms of Zhuanggu Zhitong capsule in preventing and treating experimental postmenopausal osteoporosis, while taking the lead in designing a three dimensional form to intuitively exhibit the results of the multidimensional omics study. This study provides a new idea and solution for studies on the efficacious materials and mechanisms of TCM compounds.

In order to investigate the prevalence and track genetic and antigenic evolutions of infectious bronchitis virus (IBV) and their prevalence in Guangxi, China since 1985, gene amplification and sequencing and virus neutralization (VN) test on chicken embryo tracheal organ cultures were used in genotyping and serotyping of 28 IBV isolates during 2009-2011 in Guangxi. The results of N gene sequencing and comparison showed that the 28 isolates and reference strains were classified into three groups, and most isolates belonged to group Ill, while the isolates in 1985-2008 belonged to groups IV and II. The data of VN test indicated that the 28 isolates belonged to 6 serotypes; among them, 71. 4% belonged to serotypes 1, 2, and 3, and 11 (39.3%) shared the same serotype with the current vaccine strains. Given the data of our previous study, it is found that prevalent serotypes and their proportions varied in different areas of Guangxi and during different periods. These data lay a good foundation for developing an oil-emulsified inactivated polyvalent vaccine containing local dominant serotypes for the effective prevention and control of infectious bronchitis.

Objective To explore the effect of Rational Emotive Therapy on depression and anxiety of patients with breast cancer. Methods A total of 82 patients with breast cancer were divided into the observation group (42 cases) and the contrast group (40 cases). They were investigated before and after the psychotherapy with Self-rating Depression Scale (SDS) and self-rating Anxiety Scale (SAS). Results The scores between the two groups were similar before intervention (P > 0. 05). while, after the psychotherapy, there were significant differences in each item of SDS and SAS (P <0. 01). Conclusions Rational Emotive Therapy is proved to be effective to improve the psychological status and promote healthy behaviors among breast cancer patients.

In this study, Actin, 18S rRNA, PAL, GAPDH and CPR of Artemisia annua were selected as candidate reference genes, and their gene-specific primers for real-time PCR were designed, then geNorm, NormFinder, BestKeeper, Delta CT and RefFinder were used to evaluate their expression stability in the leaves of A. annua under treatment of different concentrations of Cd, with the purpose of finding a reliable reference gene to ensure the reliability of gene-expression analysis. The results showed that there were some significant differences among the candidate reference genes under different treatments and the order of expression stability of candidate reference gene was Actin > 18S rRNA > PAL > GAPDH > CPR. These results suggested that Actin, 18S rRNA and PAL could be used as ideal reference genes of gene expression analysis in A. annua and multiple internal control genes were adopted for results calibration. In addition, differences in expression stability of candidate reference genes in the leaves of A. annua under the same concentrations of Cd were observed, which suggested that the screening of candidate reference genes was needed even under the same treatment. To our best knowledge, this study for the first time provided the ideal reference genes under Cd treatment in the leaves of A. annua and offered reference for the gene expression analysis of A. annua under other conditions.

OBJECTIVETo determine the significance of MSCT perfusion scan on differentiation of NSCLC and to investigate its possible mechanisms.

METHODSForty four NSCLC patients underwent CT perfusion scan by MSCT. Among them, 22 cases were selected to detected the two-dimensional tumor microvascular architecture phenotype (2D-TMAP), the relationships between CT perfusion parameters (BF, BV, PEI, TIP), and the differentiation of NSCLC were analysed by using the correlation analysis and trend test. Spearman correlation analysis was used to study the relationships between CT perfusion parameters, differentiation, and 2D-TMAP.

RESULTSThe total BF, BV and PEI decreased with decreasing differentiation of NSCLC (P<0.05). The total PEI showed a positive correlation with the total MVD (P<0.05). There were negative correlations between the surrounding area BF, the total BF, BV, and PEI, the uncomplete lumen of the surrounding area MVD, and expression of PCNA, respectively (P<0.05). There were positive correlations between degree of differentiation and the uncomplete lumen of the surrounding area MVD (P<0.05). It was the same as degree of differentiation and expression of PCNA, VEGF, respectively. There were positive correlations between the uncomplete lumen of the surrounding area MVD and expression of VEGF, ephrinB2, EphB4, and PCNA, respectively (P<0.05).

CONCLUSIONPerfusion parameters reflect the difference of density of vassels with mature functional lumen. Careful evaluation of the differences of blood flow pattern in pulmonary space-occupying lesions by MSCT perfusion scan can be used to identify the degree of NSCLC differentiation.

OBJECTIVETo investigate the role of the expression of ephrinB2 and EphB4 in non-small cell lung cancer (NSCLC), and their relationship with multi-slice spiral CT pulmonary perfusion imaging.

METHODSThirty-one nodules with pathologically proven NSCLC underwent CT perfusion scan. The perfusion parameters including blood flow (BF), blood volume (BV), peak enhancement image (PEI) were collected. The expression of ephrinB2 and EphB4 in tumor cells and interstitial vasculature were detected by immunohistochemistry. Correlation analysis and trend test were used to assess the relationship between ephrinB2/EphB4 expression and clinicopathological features, and between ephrinB2/EphB4 expression and perfusion parameters.

RESULTSPositive expression of ephrinB2 and EphB4 in the NSCLC group was 83.9% and 71.0%, respectively, significantly higher than that in the internal control group (P < 0.01). The expression of ephrinB2 and EphB4 was consistently in tumor parenchyma but differently in tumor vessels. The expressions of ephrinB2 and EphB4 were positively correlated with lymphatic metastasis (P < 0.05). The expression of EphB4 was negatively correlated with blood flow (BF) and blood volume (BV), respectively (P < 0.05). There was a significant positive correlation between ephrinB2 expression and BF (r = 0.516, P = 0.003), and a positive correlation between ephrinB2 expression and BV (r = 0.448, P = 0.013). The expressions of ephrinB2 and EphB4 were not correlated with PEI (P > 0.05). The values of BF and BV in the high and moderate EphB4 expression groups were significantly decreased compared with that in the negative group (P < 0.01). The value of BF in the high ephrinB2 expression group was significantly increased compared with that in the moderately positive group and negative group (P < 0.01). The value of BV in the high ephrinB2 expression group was significantly increased compared with that in the negative group (P < 0.01).

CONCLUSIONThe CT pulmonary perfusion imaging reflects the density difference of blood vessels with functional lumen, and such difference also depends on the quantity and quality of vasculature with functional lumen.
