Objective To investigate the radiosensitizing effects of cyclooxygenase-2 selective inhibitor LM-1685 on A549 cells in vitro.Methods A549 human lung adenocarcinoma cell line was used in this study.Cell growth kinetics Was determined using MTT assay.Cell survival was analyzed by clonogenic assay.The change of cell cycle Was measured by flow cytometry.Results LM-1685 inhibited the growth of A549 cells,showing a dose-dependent and time-dependent manner.LM-1685(50/μmol/L),either with or without IL-1β,showed the radiosensitizing effects on A549 cells,and the sensitizing enhancement ratio(SER)was 1.12 and 1.06,respectively.LM-1685(50 μmol/L)abrogated radiation-induced G2/M arrest of the tested A549 cells.Conclusions Cyclooxygenase-2 selective inhibitor can enhance the radiosensitivity of A549 cell line.Abrogation of radiation-induced G2/M arrest could be part of the mechanism.

OBJECTIVETo investigate diagnostic efficacy of transvaginal three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy) in assessing tubal patency with chromolaporoscopy.

METHODSA total of 157 infertile women underwent 3D-HyCoSy to evaluate tubal patency. Among these patients, 39 patients were also examined by chromolaporoscopy. The concordance of the two clinical assessment methods was analyzed by the Kappa coefficient test.

RESULTSAmong the 306 oviducts examined by 3D-HyCoSy, 99 (32.4%) were patent, 126 (41.2%) partially obstructed, and 81 (26.5%) completely obstructed. Diagnostic results with 3D-HyCoSy were not statistically different from those obtained in the 39 women (78 oviducts) who also underwent chromolaporoscopy, and the two methods showed a high concordance (k=0.747, P=0.000). The 3D-HyCoSy procedure had a sensitivity of 84.8% (28/33), a specificity of 96.2% (25/26), and positive and negative predictive values of 93.3% (28/30) and 86.2% (25/29) respectively.

CONCLUSIONTransvaginal 3D-HyCoSy can accurately reveal the spatial path and morphology of the oviduct and is a safe and effective method to evaluate tubal patency.

Objective To investigate and compare the applications of white blood cell count (WBC),neutrophil percentage (N%),C reactive protein (CRP)and procalcitonin (PCT)in the detection of bacterial infections.Methods Patients were randomly recruited in the study,70 patients with bacterial infection disease were recruited in the study as bacterial infection group,81 patients without bacterial infection were enrolled as no infection group.WBC,N%,CRP and PCT were detected,then comparative analysis of test results performed.Results Compared with no bacterial infection group,WBC,N%,CRP and PCT were increased in bacterial infection group(P <0.05),CRP and PCT increased obviously.The positive rate of WBC,N%,CRP and PCT in bacterial infection group was significantly higher than that of no bacterial infection group(P <0.05).In the bacterial infection group,the positive rate of N%,CRP and PCT was significantly higher than that of WBC(P <0.05),the positive rate of CRP was higher than PCT(P <0.05).But the positive rate of CRP was relatively high,and PCT was low in no bacterial infection group,suggesting that the false positive rate of CRP was higher,while that of PCT was lower,which had higher specificity.Conclusion WBC,N%,CRP and PCT all have clinical value for bacterial infections diagnosis.For the diagnosis of bacterial infections,N%,CRP and PCT is superior to WBC.CRP is more sensitive,but less specific,therefore,PCT with higher specificity was more suitable in the diagnosis of bacterial infections.

The levels of triglyceride(TG)and free fatty acid(FFA)in serum,liver,skeletal muscle,and pancreas of lipoprotein lipase gene knockout heterozygous(LPL+/-)mice and C57 mice were determined.Intraperitoneal glucose tolerance test(IPGTT)was performed to evaluate insulin sensitivity and β-cell function.The results showed that the Iipid content in 16 weeks LPL+/- group did not increase significantly.The TG and FFA contents in 28 weeks LPL+/- group were significantly higher than those in control and 16 weeks LPL+/-group(all P<0.05).In 50 weeks LPL+/- group,FFA levels in serum and pancreas,and TG content in pancreas increased significantly compared with other three groups(all P<0.05).The IPGTT result showed that the blood glucose levels increased from 15 to 120 min,not at 0 and 5 min.The blood glucose levels during 30-120 min increased significantly in 50 weeks LPL+/- group compared with other three groups(P<0.05).Fasting insulin(FINS),homoestasis assessment of insulin resistance(HOMA-IR)and pancreatic β cell function also increased gradually with age.FINS and HOMA-IR in 28 weeks LPL+/- group were higher than those in control and 16 weeks LPL+/- group.These results suggest that LPL is a key enzyme in lipid metabolism and plays a crucial role in the development of insulin resistance and diabetes.

The effectiveness and safety of acupuncture for the treatment of supraventricular tachycardia were systematically reviewed. The randomized controlled trials (RCTs) regarding acupuncture for supraventricular tachycardia were searched in domestic and overseas databases, and the evaluation tool of bias risk in Cochrane Handbook 5.1.0 software was used to perform the evaluation of bias risk in literature, and RevMan 5.2 software was applied for statistics and Meta-analysis. Five RCTs involving 323 patients were included. The results showed that compared with the blank control group, the acupuncture reduced the heart rate by 18.8 times/min [95% CI (12.68, 24.92)]; the clinical effective rate in the acupuncture group was superior to that in the diltiazem group [OR= 3.11, 95% CI (1.50, 6.46)]; the difference of immediate effect between propafenone and acupuncture was not significant. No reports regarding adverse events was described in 5 RCTs. As was shown in the present evidence, acupuncture is safe and effective for the treatment of supraventricular tachycardia, but the level of evidence was low and the intensity of conclusion needed to be improved.

Mouthpart developmental histology of Whitmania pigra at different month of age were studied by paraffin section, HE staining combined alcian blue and periodic acid schifts reaction procedure (AB-PAS). The following results was obtained: Change ranges: oral width 0.6 mm (1-3 month), 1.2 mm (34 month); oral diameter 0.3 mm (1-3 month); 1.2 mm (34 month), the oral size reached maximum during 4-6 months and unchanged thereafter. Oral lip had a thin protective film located in the front of the mouthpart. The W. pigra possessed three jaws in oral cavity, the big one was in dorsum, the other two separated on both side of abdomen respectively. Jaws and muscular pharynx were interrelated closely. The jaws were composed by cuticle, epithelial layer, muscularis and jaw cavity from outside to inside. In the front of jaws had mastoid abdomen with function of secreting acidophilic granule from 2 month age. Oral cavity was composed by mucosa, submucosa and muscularis inside and outside. Oral cavity was rich of peristomial nerves. And pharynx was composed of mucosa, muscularis, adventitia from inside to outside. The folds height and width become heighten and thicken. Mucosa epithelium from complex flat epithelium changed into columnar epithelium, muscularis gradually developed into thickened along with growing. Muscular thickness reached maximum at 4 months. Mucous cells of W. pigra were classified into I-IV types based on different staining and two mainly morphological shapes (Tubular, Pear-shaped). Jaws, oral cavity, pharynx by AB-PAS staining showed little changes at different month of age. Mucous cells were few at 1 month age, and type II cells were increased rapidly in 2-3 month age in oral lip. Oral cavity contains more mucous gland cells type I. Under the muscularis there were connective tissues which distributed a few of mucous cells type II.

OBJECTIVETo investigate the impact of ethanol extracts from Sedum sarmentosum (ESB) on STAT-3 signaling and its probable molecular mechanism in inducing apoptosis.

METHODMTT assay was used to detect the impact of ESB on HepG2 cell proliferation. FITC-Annexin V-FITC /PI double-labeling were used to investigate the impact on hepatoma carcinoma cell apoptosis. Western blot analysis was used to test the expression levels of cell apoptosis-related proteins Caspase-3, Caspase-9, PARP, P-STAT-3 (Tyr705) , STAT-3, Bcl-2, Mcl-1.

RESULTESB could notably inhibit proliferation of HepG2 cells, and induce HepG2 cell apoptosis, with the dose-dependent inhibitory effect. In addition, ESB could inhibit STAT-3 signaling, down-regulate Mcl-1 and Bcl-2 expressions, and induce degradation/activation of apoptosis-related proteins Caspase-3 and Caspase-9 and PARP degradation in a dose-dependent manner.

CONCLUSIONESB inhibits HepG2 cell proliferation and induces apoptosis by inhibiting STAT-3 signaling and Mcl-1 and Bcl-2 expressions.
