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.

To study the inhibitory effect of gigantol on proliferation, migration and invasion of human osteosarcoma U20S cells and to explore the mechanism. Methods: After being treated with different concentrations (10, 25, 50, 75, 100, 150 µmol/L) of gigantol for 24 and 48 h, the proliferation of U20S cells was detected by CCK-8 assay. Transwell assay was used to detect the effects of 25 µmol/L and 50 µmol/L gigantol on the migration and invasion abilities of U20S cells. The lipopolysaccharide (LPS) was used to induce inflammatory reaction in U20S cells before gigantol treatment; qPCR and WB were used to detect the mRNA and protein expressions of NF-κB (p65), TNF-α, IL-6 and PRL-3, respectively. Results: Different concentrations of gigantol could all inhibit the proliferation of sarcoma U20S cells at different time (P<0.05 or P<0.01). The 25 µmol/L and 50 µmol/L of gigantol could significantly inhibit the migration and invasion of osteosarcoma U20S cells (all P<0.01); at the same time, it could inhibit the protein expressions of NF-κB, TNF-α, IL-6 and PRL-3 (P<0.05 or P<0.01). After LPS induction, the mRNA and protein expressions of NF-κB, TNF-α, IL-6 and PRL-3 in U20S cells were significantly increased (all P<0.01); however, the consequent treatment with gigantol (25 and 50 µmol/L) reversed the effects of LPS on U20S cells obviously (P<0.05 or P<0.01). Conclusion: Gigantol can inhibit the proliferation, migration and invasion of osteosarcoma U20S cells, and its mechanism may be related to the regulation of NF-κB/PRL-3 signaling pathway.

Objective To compare the analgesic efficacy and safety of the sole local anesthetic ropivacaine with the combination of both local anesthetic ropivacaine and opioidergic analgesic sufen-tanil given epidurally on the labor pain control.Methods After institutional review board approval and patient consent,a total of 481 nulliparas requesting epidural labor analgesia were randomized into two groups:a sole local anesthetic group (0.125% ropivacaine,group R)and a combination of local anesthetic and opioidergic analgesic group (0.125% ropivacaine+0.3 μg/ml sufentanil,group RS). Analgesic efficacy was measured using numerical rating scale (NRS)of pain and maternal visual ana-logue scale (VAS)analgesia satisfaction with regard to the first and the second stage of labor.Anal-gesic safety was measured with the Bromage scale of maternal safety and epidural labor analgesia re-lated side effects,as well as fetal safety including Apgar scoring and umbilical cord artery blood gas a-nalysis.Results A total of 346 participants completed the study,with 1 64 and 182 women in each group R and RS,respectively.The median NRS pain score during the first stage of labor was signifi-cantly lower in the combination group (2.2,IQR:1.8-2.7 )comparing to the sole local analgesic group (2.4,IQR:2-2.8)(P <0.001).No significant difference was observed in NRS pain score dur-ing the second stage of labor.Patients in both groups were rated the same VAS satisfaction of analge-sia.Patients in the sole local analgesic group experienced fewer side effects than those in the combina-tion group (37.7% versus 47.2%,P =0.082).The incidence of 1-min Apgar≤7 was lower in the sole local analgesic group 2 (1.2%) than the combination group 10 (5.5%) (P < 0.05 ). Conclusion The sole local anesthetic ropivacaine produces a comparable labor analgesic effect as the combination of both local anesthetic ropivacaine and opioidergic analgesic sufentanil but the former has less maternal side effects,and less incidence of lower 1-min Apgar scoring.
