OBJECTIVEIn this study, we aimed to investigate the expressions of adhesion molecules on human bronchial epithelial cells and neutrophils in co-culture system, assess the effects of puerarin on suppressing these adhesion molecules expressions, and explore the roles of two crucial signal-transduction elements p38 mitogen-activated protein kinase (p38 MAPK) and nuclear factor kappa B (NF-κB) in modulating adhesion molecules expressions.

METHODSNeutrophils and BEAS-2B cells (one human bronchial epithelial cell line) were co-cultured, and adhesion molecules expressions on cell surface were detected using flow cytometry. The mRNA levels of adhesion molecules were assessed by real-time quantitative polymerase chain reaction (real-time qPCR). Phosphorylated p38 MAPK and inhibitor κB were analyzed by Western blot.

RESULTSIn co-culture system, adhesion molecules expressions on BEAS-2B cells and neutrophils were enhanced significantly (P<0.05). Correspondingly, the mRNA levels of adhesion molecules were also increased greatly. Moreover, the pretreatment of peurarin obviously suppressed adhesion molecules expressions on cell surface. Furthermore, phosphorylated p38 MAPK and inhibitor κB in BEAS-2B cells and neutrophils were elevated in co-culture system, but decreased significantly after upon the treatment of peurarin (P<0.05).

CONCLUSIONSCoculture boosted the interactions between human bronchial epithelial cells and neutrophils mimicking airway inflflammation, whereas peurarin decreased the expression of adhesion molecules on cell surface by suppressing the activities of p38 MAPK and NF-κB pathways, and exhibiting its anti-inflflammation activity.

OBJECTIVETo analyse clinical feasibility of two electrophoresis procedures of seminal plasma proteins, agarose gel electrophoresis and SDS-agarose gel electrophoresis.

METHODSSixty-nine semen samples were examined and classified into three groups: the asthenozoospermia (n = 22), the asthenoteratozoospermia (n = 19), and the relative normal group (n = 28) with normal routine and special test results, according to WHO routine and special test criterion. Then, the seminal plasma protenis were separated by two different electrophoresis, with SDS-agarose and agarose support medium, the buffer pH 7.0 and 9.2 respectively. The agarose gel electrophoresis was done under various sample loading time, motion power and staining modules. The completed gels were scanned and compared the each other statistically.

RESULTSSeminal plasma proteins can be separated into 4 strips by SDS-agarose gel electrophoresis with acid crystal violet, and the strips were diffusion and with dark background. However, 6 clear strips named A, B, C, D, E, and F can be obtained by agarose gel electrophoresis with 6 min. After samples were loaded and stained by amidoblack, there showed appropriate spaces among strips, and it was very easy to scan the drying gel by a densitometer. Using agarose gel electrophoresis, the statistical difference in strip C and E was shown between the asthenozoospermia and the relative normal group, and between the asthenozoospermia and the asthenoteratozoospermia, however, not between the relative normal and the asthenoteratozoospermia group. Moreover, the samples in the relative normal group with normal routine and special test results were in different electrophoresis maps.

CONCLUSIONAgarose gel electrophoresis of seminal plasma proteins with buffer pH 9.2, 6 min. sample loading and amidoblack stain was a simple, fast and fit technique for clinic.

Objective To investigate the effects of different standard cross sections and angles on the measurement accuracy of induced postnatal fetal long bones. Methods Fetal long bones (femori and humeri) in 30 cases with induced abortion were measured utilizing ultrasound from different angles and /or at different directions. The values measured from different sections and angles with vernier calipers were compared prenatally and postnatally. Results There was no apparent difference between the pre-induced abortion and those of the post-induced abortion. The results in the 30 cases showed that: (1) the values measured from anterior 90 degree, the long bone length would best match with the bare long bone length up to 96.7%, the match rate of other angles and/or directions was up to 80%; (2) no apparent statistical difference was between the length of left and right bone and no difference was found using 4 different directions and 3 different angles; (3)there was no difference between the left and right femuri and humeri.Conclusions Though the measured value from anterior 90 degree direction was the most accurate one, the statistical analtical results showed no difference among 12 values measured from 3 different angles and/or 4 different directions.

Objective:To compare the diagnostic values of C-TIRADS, ACR-TIRADS and EU-TIRADS.Methods:According to the classification methods of the 3 guidelines, the ultrasonographic features of 283 thyroid nodules from 266 patients in Sir Run Run Shaw Hospital from January 2019 to June 2020 were analyzed retrospectively. The pathological results were taken as the gold standard, the malignant percentage of different classification was calculated, the ROC curve was plotted, the area under the ROC curve (AUC) and the best diagnostic cut-off value were calculated, and the diagnostic values of the three guidelines were compared. According to the FNA recommendations of the guidelines, the recommended number of thyroid nodules and the detection rate of malignant nodules in different guidelines were analyzed.Results:The AUCs of C-TIRADS, ACR-TIRADS and EU-TIRADS were 0.80, 0.66, 0.61, respectively. The AUC of C-TIRADS was higher than those of ACR-TIRADS and EU-TIRADS ( P<0.001, P<0.001). The best diagnostic cutoff values of C-TIRADS, ACR-TIRADS and EU-TIRADS were 4C, 5 and 5, respectively. Under the critical points, the sensitivities of the 3 guidelines were 95.27%, 98.10%, 99.53%, the specificities were 54.17%, 33.33%, 20.83%, respectively. There was no significant difference in the number of FNA recommendations among the 3 guidelines(all P>0.05), their FNA recommendations were highly consistent (Kappa>0.9). Conclusions:The diagnostic value of C-TIRADS in the classification of benign and malignant thyroid nodules is higher than those of ACR-TIRADS and EU-TIRADS. The best critical value for diagnosis of thyroid nodules is C-TIRADS 4C. The three guidelines are similar in the number of FNA recommendations and the detection rate of malignancy.

Given that the current Newcastle disease virus (NDV) infection in wild birds poses the threat to poultry, surveillance of Newcastle disease in captive wild birds was carried out in Jilin, China in 2018. Here, an NDV strain obtained from toco toucan was firstly characterized.The results showed that the F gene of the NDV isolate Toucan/China/3/2018 is classified as genotype II in class II. Sequence analysis of the F0 cleavage site was 113 RQGR/L 117 , which supports the result of the intracerebral pathogenicity index assay indicating classification of the isolate as low-pathogenicity. Experimental infection demonstrated that Toucan/ China/3/2018 can effectively replicate and transmit among chickens. To our knowledge, this is the first report on genetically and pathogenically characterizing NDV strain isolated from toucan, which enriches the epidemiological information of NDV in wild birds.
