Objective To explore the effect of TLR2 on collagen Ⅰ(colⅠ) in adipose tissue of high-fat-diet induced obese mice.Methods Male C57bl/6J mice and TLR2 knockout mice were divided into groups according to high fat diet or normal chow.Total collagen, TLR2, colⅠ, MMP1, MMP2, TIMP1, colⅠα1 mRNA and colⅠα2 mRNA in adipose tissue were measured at the end of the experiments.Results Total collagen, TLR2, colⅠ, MMP2, TIMP1, colⅠα1 mRNA, and colⅠα2 mRNA in adipose tissue increased while MMP1 in adipose tissue decreased in mice with high fat diet.Decreased levels of total collagen, colⅠ, MMP2, TIMP1, colⅠα1 mRNA and colⅠα2 mRNA in adipose tissue were detected in TLR2 gene knockout mice with high fat diet.However, there was an increased level of MMP1 in TLR2 gene knockout mice with high fat diet.Conclusion In high-fat-diet induced obese mice, deposition of colⅠ in adipose tissue seems to be alleviated by TLR2 gene knockout via MMP1 and TIMP1.

OBJECTIVE: To evaluate the diagnostic value of multi-slice spiral CT (MSCT) for plasma cell mastitis. METHODS: Radiographs of MSCT for forty-six patients with plasma cell mastitis diagnosed by pathological examination were reviewed. RESULTS: The findings of MSCT of plasma cell mastitis could be divided into four types, including the inflammation type, the abscess type, the sinus and fistula type, and the mixed type, and each type had its radiographic characteristics. CONCLUSION: MSCT is helpful for diagnosing plasma cell mastitis and should be used as an examination of first choice for the patients.

Objective To evaluate the clinical application of the fistulography of multi-slice spiral CT(MSCT)in the diagnosis of anal fistula.Methods A total of 28 patients who were verified operatively of fistula in ano underwent preoperative fistulography of MSCT.The multi-planar reformation(MPR)and surface shadow display(SSD)images were generated and analyzed retrorespectively.Results There were 8 cases with perianal abscess and 20 cases with anal fistula in 28 patients.Complex fistula was diagnosed in 16 cases,and simple inter-sphincteric fistula was found in 4 cases;the inner orificiums of anal fistulas were revealed accurately with MPR images in 18 cases.Conclusion The fistulography of MSCT is valuable for preoperative assessment of anal fistula,in particular for investigation of the inner orificiums of anal fistulas with MPR.

Purpose To investigate the expression of estrogen receptor ( ER) and progesterone receptor ( PR) in endometrial tissue in patients with intrauterine adhesion ( IUA) and their clinical significance. Methods Two experimental methods, immunohistochemical MaxVision two step method and real-time fluorescencequantitative PCR ( qRT-PCR) , were used for detection of ER and PR in endome-trial tissue both in group IUA ( study group) and non IUA group ( control group) . Results MaxVision immunohistochemical method showed that ER protein expression in the study group (3. 52 ± 0. 71) was significantly higher than that (2. 75 ± 1. 00) in the control group (P=0. 01), ER mRNA expression by qRT-PCR was also significantly higher in the study group (1. 59 ± 0. 26) than that (1. 00 ± 0. 19) in the control group (P=0. 00). The immunohistochemical detection of showed that PR protein expression in the study group (3.26 ±0.70) had no significant different from that (3.58 ±0.28) in the control group (P=0.12), qRT-PCR also showed that ER mRNA in the study group (1.15 ±0.21) had no significantly different from that (1.00 ±0.31) in the control group (P=0. 21 ) . Immunohistochemical expression of ER and PR proteins showed a significant difference between the endometrial glands and en-dometrial stroma (χ2 =5. 797, P=0. 016,χ2 =4. 857, P=0. 027). Conclusion The expression of ER in endometrial tissue in the study group is higher than that in the control group, but the expression of PR has no different between the two groups, ER and PR pro-teins expression are higher in endometrial glands than that in endometrial stroma. These provide a theoretical reference for clinical use of estrogen and progesterone to IUA patients.

BACKGROUND:Phytohemagglutinin (PHA) can stimulate the peripheral blood mononuclear cells (PBMCs) into cellcycle, and cause their immune activation, which is a common immune proliferation model. However, the role of non-PBMC ingredient of peripheral blood is unclear, as wel as the expression of endothelial cells related cytokines. OBJECTIVE:To study the effect of whole blood culture and PBMCs alone culture with PHA on the PBMC proliferation and apoptosis, expression of inflammatory cytokine and endothelial cellsecreted cytokine markers. METHODS:Morphological changes of PBMCs separated from normal karyotype human peripheral blood individual y cultured with or without PHA were observed. The PBMCs were col ected by whole blood culture or PBMC separated culture. mRNA was extracted for the fluorescence quantitative RT-PCR, which was applied to detect the cellproliferation, apoptosis, and expression of inflammatory cytokine and endothelial cellsecreted cytokines. The statistic analysis was used for the significance explication. RESULTS AND CONCLUSION:PBMCs alone cultured ere different from those undergoing whole blood culture. The PHA could up-regulate the gene expression of Ki67, proliferating cellnuclear antigen, Caspase 3, interferon-γ, tumor necrosis factor-βand interleukin-6, but down-regulate Protein C. This indicted that PHA could promote the proliferation and apoptosis of PBMCs and up-regulate the expression of inflammatory cytokines, but down-regulate the expression of endothelial cells secreted coagulation cytokines.

Diabetic vascular complications are the key cause of the poor life quality and high mortality in diabetic patient. Advanced glycation end products (AGEs) and its cross-links play important roles in the diabetic vascular complications. Endothelial cells damage induced by AGEs may account for the initial agent for diabetic vascular complications. Recent studies have shown that AGEs inhibitors and breakers can prevent and reverse these complications. This article reviewed the research progress of AGEs and endothelium dysfunction. The potential therapeutic method was also stated.

Methods: Heparanase gene-targeted hairpin siRNA was designed, two complementary oligonucleotide strand was synthesized and inserted into pGPU6/GFP/Neo vector,which was identified by sequence identify. Human malignant breast cancer MDA-MB-231 cells were transfected with the constructed vector with lipofectamine method. Western blot was per-formed to evaluate the expression of heparanase protein. Results: Four kinds of heparanase gene-targeted hairpin siRNA were designed, and were inserted into pGPU6/GFP/Neo vector after annealing. The vector containing siRNA was proved to be right by sequencing. The result of Western blot indicated that the expression of heparanase could be degraded by siRNA. Conclusion: The expression of heparanase can be degraded by siRNA method, and HPSE-A and HPSE-B showed the best results.
