Different from fasting blood glucose reflecting the basal glucose level of the body, the post-prandial blood glucose gives us the information about the highest glucose level during a day. It has been proved that post-prandial hyperglycemia (PPG) is associated with cardiovascular diseases more closely, which may be caused by oxidative stress, hence the management of PPG is of great meanings. But what is the effect of PPG control on the treat-to-target blood glucose management? This is a question worth discussing.

Objective Wnt signal is very important to control the gastrointestinal mucosal proliferation, but its role in the gastric mucosal proliferation after acidified ethanol injury is not clear yet,neither is the relationship with cyclooxygenase 2 (COX-2). Methods X-gal staining was used to measure the expression of Wnt signaling; Western blot and RT-PCR were used to measure the expression of TCF4 and P-Catenin in the gastric mucosa before and after acidified ethanol injury. We also used TOP/flash plasmid to further indentify the relationship between COX-2 and Wnt signal pathway. Results After acidified ethanol injury, the expression of LacZ signal, β-Catenin and TCF4 increased only in the wild type mouse. The expression of β-Catenin and TCF4 protein increased about (3.52 ±0.52) times and (3.02 ±0.62) times separately, and the expression of β-Catenin and TCF4 mRNA increased about (19. 85 ±3.63) times and (17.82 ±4.82) times separately. Without ethanol injury, the expression of TOP/flash plasmid was inhibited by COX-2 inhibitor (NS398) about 80% and promoted by prostaglandin E2(PGE2) about 50%.After 1% ethanol injury, the expression of plasmid was inhibited by NS398 about 25% ; on the contrary,PGE2 promoted the expression about 10%. Conclusion Wnt signal in gastric mucosa is activated after acidified ethanol injury. COX-2 may work through modulating Wnt signal to control the proliferation of gastric mucosa.

Objective To generate a comD gene knock-out mutant of Streptococcus pneumoniae,and determine the correlation of comD gene and the bacterial resistance against β-lactam antibiotics and understand the effect of closantel down-regulating comD, comE and comC mRNA levels. Methods A suicide plasmid pEVP3comD was constructed for comD gene knock-out and a comD gene knock-out mutant (comD-)was generated through homologous recombination and insertion inactivation. PCR and immunofluorescence method were used to identify the comD- mutant and real-time fluorescence quantitative PCR was applied to detect the changes of comD, comE and comC mRNA levels before and after closantel treatment in comD-mutant and wild-type strain. Double agar dilution method was performed to determine the sensitivity of comD- mutant and wild-type strain to penicillin G and cefotaxime. Results The comD gene in genome DNA of the generated comD- mutant was inactivated by sequencing and immunofluorescence detection. 50 μ mol/L or 100 μmol/L closantel had a function to down-regulate the comD, comE and comC mRNA levels ( P ＜ 0. 05) whereas 25 μmol/L closantel did not. Both the MIC values of penicillin G and cefotaxime inhibiting comD- mutant were 32 μg/ml which was significantly higher than that of wild-type strain (0.06 μg/ml and 1 μg/ml). Conclusion In this study a comD gene knock-out mutant of S. pneumoniae was successfully generated. There is a close correlation between comD gene and β-lactam antibiotics resistance of S. pneumoniae. Closantel has a function to inhibit the competence formation of S. pneumoniae through down-regulating the transcription levels of comD, comE and comC genes.

The precise measurement in lens thickness in vivo, provides great application value for intraocular accommodation and ametropia development mechanism research.And it has great clinical significance for the diagnosis and treatment of glaucoma and cataract.Currently, many ultrasonic methods and optical methods are used in measuring lens thickness.The measurement principles, advantages, disadvantages and the accuracy of the instruments are summarized in this paper.Among these methods, Orbscan II, Pentacam, Lenstar and AS-OCT can be used to measure lens thickness instead of A-scan.More important is the fact that UL-OCT can dynamically monitor the change of the lens thickness with intraocular accommodation.Choosing an instrument with higher measuring accuracy to examine the lens thickness, can provide more accurate and convincing lens thickness data for clinical and scientific research.

Objective·To investigate the role of collagen triple helix repeat containing-1 (CTHRC1) in ovarian cancer cell metastasis and the related mechanism. Methods·The expression of CTHRC1 in ovarian cancer cells was detected by Western blotting. The cell line which had high expression of CTHRC1 was transfected with a CTHRC1 specific shRNA, and the lenti-CTHRC1 was used to overexpress CTHRC1 in the cell line whose expression of CTHRC1 was very low. Then the expression of Slug and MMP-2 was assessed. Transwell assay was used to determine the migration and invasion capability of ovarian cancer cells after transfection. Results·The expression of CTHRC1 in HO8910 cells was the lowest, while the CTHRC1 protein level was dramatically increased after transfection of lenti-CTHRC1. Meanwhile, there was a distinct rise of the migration and invasion ability, as well as the expression of Slug and MMP-2 (all P<0.05). Conversely, CaOV3 cells had a higher protein expression of CTHRC1. By using lenti-shCTHRC1, a remarkable knockdown of CTHRC1 was obtained. Likewise, the capability of migration and invasion was decreased, and the Slug and MMP-2 expression was reduced (all P<0.05). Conclusion·CTHRC1 might positively regulate Slug and MMP-2 to promote ovarian cancer cell metastasis.
