Objective To summarize the contrast enhanced ultrasonographic (CEUS) features of benign focal liver lesions, on and to investigate the value of contrast enhanced ultrasound techniques in the diagnosis of benign focal liver lesion. Methods The contrast enhanced ultrasonographic performance of 68 benign focal liver lesions cases which were dififcult for routine ultrasound diagnosis and conifrmed by pathology or follow-up were retrospectively analyzed. Chi-square test of four-fold table were used to compare the diagnostic coincidence rate of conventional ultrasound and contrast-enhanced ultrasound. Results The 68 cases of benign focal liver lesions included complex cysts (n=7), liver hydatids (n=2), liver abscess (n=15), focal nodular hyperplasia (n=8), angiomyolipoma (n=2), hepatocellular adenoma (n=4), focal fat accumulation (n=16), inlfammatory pseudotumor (n=12), solitary necrotic nodule (n=1), intrahepatic biliary cystadenoma (n=1). There were no enhancement among 7 complex cysts, 2 liver hydatids and 1 solitary necrotic nodule. Isoenhancement was detected in focal fat accumulation (n=16);hypoenhancement during the arterial phase and sustained enhancement during the portal or late phase was found in focal nodular hyperplasia (n=8) and angiomyolipoma (n=2). Grid-like enhancements during the arterial phase and isoenhancement or hypoenhancement during the portal phase, and hypoenhancement during the late phase was presented in liver abscess (n=15). Hyperenhancement during the arterial phase were detected in 4 cases of hepatocellular adenoma, 3 of which showed isoenhancement or hyperenhancement during the portal and delayed phase, one case showed hypoenhancement during the portal phase. Eight cases of all the inlfammatory pseudotumor showed no enhancement during all phases;3 cases showing grid enhancement during the arterial phase and the enhancement washed out rapidly;1 case showed mild edge enhancement during the arterial phase and hypoenhancement during the delayed phase. The solid part of the intrahepatic biliary cystadenoma showed hyperenhancement during the arterial phase and hypoenhancement during the portal and late phase.The central area showed no enhancement during all phase. The coincidence rate between pathology and conventional ultrasound diagnosis was 61.8%(42/68). The coincidence rate between pathology and contrast- enhanced ultrasound diagnosis was 92.6%(63/68). The coincidence rate of contrast-enhanced ultrasound diagnostic was higher than that of conventional ultrasound, with a statistically signiifcant difference (χ2=8.17, P < 0.01). Conclusion Real-time gray-scale contrast-enhanced sonography can improve the accuracy of the diagnosis and differential diagnosis for benign focal liver lesions.

BACKGROUND:In recent years, studies on the application of traditional Chinese medicine in bone tissue engineering are stil at the initial stage in China. Reports about psoralen antibiotic biphasic ceramic bone have not been seen in bone tissue engineering research. OBJECTIVE:To fabricate the psoralen antibiotic biphasic ceramic bone by vacuum evaporator and to observe the physicochemical properties, antibiotic activity and biocompatibility of the material. METHODS:Biphasic ceramic bone was prepared by twice low-temperature calcining pig vertebrae combined with sodium pyrophosphate, and then the ceramic bone was immersed in chitosan/psoralen compound solution to prepare psoralen antibiotic biphasic ceramic bone. The surface morphology was observed by scanning electron microscope, and the compressive strength was tested. Antibiotic activity of the psoralen antibiotic biphasic ceramic bone on Escherichia coli and Staphylococcus aureus was tested by microbiological methods. Mouse osteoblasts MC3T3-E1 were co-cultured with the psoralen antibiotic biphasic ceramic bone for 4 and 8 days, and the cel adhesion and proliferation on the scaffold surface were observed under the scanning electron microscope. RESULTS AND CONCLUSION:Psoralen antibiotic biphasic ceramic bone had natural pore structure with the trabecular bone, trabecular space and lumen system and exerted great antibiotic effect on Escherichia coli and Staphylococcus aureus. The compressive strength was (4.69±0.50) MPa. Mouse osteoblasts MC3T3-E1M could be adherent to the psoralen antibiotic biphasic ceramic bone and proliferate rapidly, suggesting the psoralen antibiotic biphasic ceramic bone has good cytocompatibility.

Objective:To explore the relationship between contact lens (CL) related dry eye and morphological changes of meibomian glands.Methods:A cross-sectional study was performed.A total of 157 consecutive subjects (314 eyes) to underwent refractive surgery from May 2014 to June 2015 in Tianjin Medical University Eye Hospital were included.The subjects wearing soft CL for a long time were divided into CL group (182 eyes of 91 subjects), while the subjects who never wore CL were divided into the control group (132 eyes of 66 subjects). The ocular surface disease index (OSDI) questionnaire, tear meniscus height (TMH), first non-invasive tear film breakup time (fNIBUT), average non-invasive tear film breakup time (avNIBUT) and corneal fluorescein staining (CFS) score of all subjects were collected and analyzed.Morphological evaluation of meibomian glands were performed.The meibomian glands dropout ratio of upper eyelid, lower eyelid and total meibomian gland area as well as meibomian glands distortion number of the two groups were compared.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Tianjin Medical University Eye Hospital (No.2014KY[L]-09). Written informed consent was obtained from each patients prior to any examination.Results:The OSDI score, CFS score, TMH, fNIBUT and avNIBUT were 16.67(10.00, 25.00), 13.88(7.50, 18.26), 0.20(0.17, 0.23) mm, 5.64(3.95, 7.92)s and 8.56(6.56, 12.12)s in CL group, respectively, while 13.88(7.50, 18.26), 1.00(0.00, 2.00), 0.22(0.17, 0.29) mm, 7.33(4.54, 13.21)s and 11.49(7.46, 17.83)s in the control group, respectively.Compared with the control group, the CL group had the higher OSDI score, higher CFS score, lower TMH, lower fNIBUT, lower avNIBUT, and the differences were significant (all at P<0.01). The MG dropout ratio and meibomian gland distortion number were (29.42±12.24)% and 4(3, 6) in CL group, respectively, while (20.37±10.83)% and 3(1, 4) in the control group, respectively.In comparison with the control group, the CL group had the higher MG dropout ratio and greater meibomian gland distortion number ( t=6.76, P<0.01; U=7 656.00, P<0.01). A positive correlation was found between the total meibomian gland area dropout ratio and duration of CL wearing ( rS=0.404, P<0.01), OSDI scores ( rS=0.275, P<0.01), CFS scores ( rS=0.319, P<0.01). Conclusions:Long-term wearing of CL can lead to severe ocular discomfort, dry eye syndrome and morphological alterations in meibomian gland, suggesting that morphological abnormality of meibomian gland is presumably associated with the occurrence of ocular discomfort and dry eye syndromes in CL wearers.

ObjectiveTo investigate the effects of glioma microenvironment and COX-2 inhibitor celecoxib on the phenotypes and function of dendritic cell (DC).MethodsThe expression of cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) production were detected in glioma C6 cells treated with different concentration of celecoxib.Monocytes were isolated from human peripheral blood and cultured with 200 ng/ml rhGM-CSF and 50 ng/ml rhIL-4,either C6 tumor cells supernatant (TSN) or TSN from C6 cells treated with celecoxib to generate DCs.Cell morphology was observed.Cell phenotype including CD1a,CD80,CD83 and D86 were analyzed on a FACScan.Production of IL-12 in DC supernatant and the potential to stmiulate allogeneic T cell proliferation were detected.ResultsThe expression of COX-2 and PGE2 production in C6 cells decreased after treated with celecoxib in a concentration dependant manner.Typical DCs were induced in all groups and the expression of CD1a ((75.56±2.40)％,(75.09±3.67)％,(76.03 ±3.43)％),CD83((72.04±3.45)％,(71.44±3.78)％,( 73.63 ± 3.31 ) ％ ) had no difference (P ＞ 0.05 ).Expression of CD80 ( ( 58.41 ± 3.85 ) ％ ),CD86 ( ( 58.22 ±3.25)％ ) in DC with TSN obviously decreased compared with normal group( (70.36 ± 2.91 )％,(69.31 ±4.29 ) ％,P ＜ 0.01 ) as well as the IL-12 production ( ( 137.88 ± 5.33 ) pg/ml,( 186.04 ± 4.76 ) pg/ml) and the potential to stmiulate allogeneic T cell proliferation ( P ＜ 0.01 ).Celecoxib increased the expression of CD80,CD86 (66.83 ± 2.51,63.51 ± 5.47,P＜ 0.01 ) in DC and the same as IL-12 production( ( 170.31 ± 3.46) pg/ml,P ＜ 0.01 ) and the potential to stmiulate allogeneic T cell proliferation ( P ＜ 0.01 ),which were lower than the normal level.ConclusionGlioma microenvironment may induce the celecoxib can inhibit the expression of COX-2 and PGE2 in gliomas cells and improve the phenotypes and function defect of DCs.

Aim To detect the effects of cetuximab combined with adriamycin on the proliferation and ap-optosis of triple-negative breast cancer cells.Methods Cell viability was evaluated by MTT assay.The cell apoptosis was analyzed by flow cytometry with propidi-um iodide staining.JC-1 staining was used to deter-mine mitochondrial membrane potential.The expres-sions of glucose regulated protein78 (GRP-78),Bcl-2 and Caspase-3 were measured with Western blot.Re-sults MTT assay showed that cetuximab had inhibi-tion effect on the breast cancer cell MDA-MB-231 growth,and the effect was related to concentration of drug.The inhibition effect of adriamycin on MDA-MB-231 had remarkabe relationship with time and concen-tration.When combined with each other,they could re-markably increase inhibition effect.The viability of cells in combination group for 1 2 h,24 h,48 h,sig-nificantly lower than that in cetuximab or adriamycin group (P <0.05 or P <0.01 ).Apoptosis results showed that cell apoptosis was significantly increased when cetuximab combined with adriamycin,reached (43.93 ±3.59)% for 24 h,had remarkably statistical significance compared to cetuximab or adriamycin
group (P <0.01 ).JC-1 staining indicated that cetux-imab or adriamycin could reduce the mitochondrial membrane potential,but the reduction effect was more remarkable in the combination group.Western blot re-vealed that cetuximab could reduce the expression of GRP-78 and Bcl-2,and increased the expression of Caspase-3 and its activity.The expressions of Bcl-2, Caspase-3 had no significant change in adriamycin group,but GRP-78 was increased.In combination group,the expression of GRP-78 and Bcl-2 was signifi-cantly decreased,but Caspase-3 was increased nota-blely compared to adriamycin group.Conclusions The combination of cetuximab and adriamycin enhances the inhibition effect on the triple-negative breast cancer MDA-MB-231 cells,and increases cell apoptosis.The mechanism may be that cetuximab reduces the endo-plasmic reticulum stress level,then activates the mito-chondrial pathways by decreasing the expression of Bcl-2,reducing the mitochondrial membrane potential,and promoting cell apoptosis.
