One year after surgical treatment, there were no phonologic disorders caused by tongue motion in children <1 year old, but the levels of phonologic prognosis in children >1 years old were better, moderate, and insignificant respectively.ConclusionThe ideal surgical period of children with tongue-tie is age of 6～12 months.

AIM:To investigate the potential role of Sonic hedgehog (Shh) signaling pathways in the radioresistance of esophageal cancer.METHODS:Radioresistant cell line Eca109R was established by repeating X-ray irradiation at dose of 60 Gy in total using Eca109 cells as parental cells.The radiosensitivity of the parental and radioresistant cells was confirmed by colony formation assay.The cell viability was detected by CCK-8 assay.The intracellular protein levels of Shh and Gli1 were determined by Western blot and immunofluorescence.RESULTS:The survival fractions at dose of 2 Gy for Eca109R cells and Eca109 cells were 0.937±0.013 and 0.499±0.042, respectively.The inhibitory rate of cell viability decreased gradually in the Eca109R cells (P<0.05), suggesting that the radioresistant cell line was successfully established.The results of Western blot indicated that the protein expression of Shh and Gli1 was much higher in the Eca109R cells than that in the Eca109 cells (P<0.05).Immunofluorescence staining showed that Gli1 was expressed in the cytoplasm and nucleus, and presented nuclear clustering in the Eca109R cells.The positive rate of Gil1 expression in Eca109 cells was 52.3%± 0.035%, while that in Eca109R cells was 87.6%±0.021% (P<0.05).CONCLUSION:The radioresistance of esophageal cancer may be related to the activation of Shh signaling pathways with over-expression of Gli1 and other related proteins.

Objective To investigate the suppression effects of Tripotolide (TL) on the pancreatic cancer xenograft models and angiogenesis. Methods The growth suppression effect of TL on SW1990 was determined using cell count kit (CCK-8), apoptotic cells induced by TL were examined by morphology and terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) assay. The inhibitory effects of TL on the growth of tumor xenografts and tumor microvascular density (MVD) were investigated. ResultsTL inhibited the growth and proliferation of SW1990 cells in a concentration-dependent and time-dependent manner. The inhibition ratios of cells treated at 160 mg/ml TL for 24 h was 50. 6%, the apoptotic rate increased from 9.6% in the control group to 45.1% (P <0.01 ). The inhibition rate of cancer xenograft growth was 89.9% when TL was intratumorally injected at the dose of 0.5 mg/kg. The expression of VEGF in tumor tissue decreased while MVD also decreased from 36.25±8.64 to 9.87±3.34 (P <0.01 ). ConclusionsTL induced prominent growth inhibition and apoptosis in human pancreatic cancer cell lines. TL.can attenuate the growth of pancreatic caner xenografts through its effect on antiangiogenesis.

A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the determination of butoconazole in human plasma. Human plasma samples of 0.2 μL were pretreated by a single step protein precipitation procedure and analyzed using a high performance liquid chromatography (HPLC) electrospray tandem mass spectrometer system. The compounds were eluted isocratically on an Inertsil ODS-SP column (100 mm×2.1 mm, 3 μm), ionized using a positive ion atmospheric pressure electrospray ionization source and analyzed using multiple reaction monitoring (MRM) mode. The ion transitions monitored were m/z 412.8→165.1 for butoconazole and m/z 453.4→230.3 for the internal standard. The chromatographic run time was 3.5 min per injection, with retention time of 2.47 min and 2.15 min for butoconazole and repaglinide, respectively. The method was validated to be linear over the range of 20 to 8000 pg/mL (r>0.999) by using a weighted (1/x(2)) quadratic regression. The mean recovery rate was more than 86.7%, and the intra- and inter-day precision of the quality control samples (QCs) was less than 8.3% and the accuracy ranged from 96.0% to 110.2%, which indicated that the quantitative method was reliable and accurate. The method is simple, rapid, and has been applied successfully to a pharmacokinetics study of butoconazole nitrate suppositories in healthy Chinese females.

OBJECTIVETo evaluate the effect of chronic virus infection on laboratory tests results in patients with osteoarticular tuberculosis.

METHODSA total of 121 patients with osteoarticular tuberculosis, who were hospitalized in Shenzhen Third People's Hospital during June 2008 to June 2012, were recruited for analysis. Clinical laboratory tests results were collected for comparison between patients with or without chronic co-infection with virus.

RESULTSAmong the 121 patients, thirty patients were co-infected with hepatitis B virus (HBV), two were with Human immunodeficiency virus (HIV), and one was co-infected with HBV, HIV and hepatitis C virus (HCV). Compared to patients with osteoarticular tuberculosis without HBV/HCV/HIV infection, patients with chronic HBV/HCV/HIV virus infection had similar positive rate of laboratory tests including tissue smear acid-fast bacilli (AFB) staining, tissue Mycobacterium tuberculosis (Mtb) culture, tissue Mtb DNA detection, serological test of antibodies against Mtb, and Mtb. antigen-specific interferon-gamma release assay. Similar results were also found for erythrocyte sedimentation rate, C-reative protein level and liver function including Alanine aminotransferase and Aspartate Aminotransferase.

CONCLUSIONChronic infection with HBV/HCV in patients with have no obvious effect on clinical laboratory tests related to tuberculosis.
