This study examined the effects of Bangdeyun on the expressions of nuclear factor-kappaB (NF-kappaB), interferon-gamma (IFN-gamma) and interleukin-10 (IL-10) in the endometrium of mice with embryo implantation dysfunction (EID) during the implantation time (namely on pregnancy day 5, 6, 7 and 8) and explored the local immune regulatory effects of Bangdeyun. The gestational mice were randomly divided into normal group, model group and Bangdeyun-treated group. EID models of mice were established by using indomethacin. The endometrial expression of NF-kappaB was detected by immunohistochemistry and Western blotting. IFN-gamma and IL-10 were measured by enzyme-linked immunosorbent assay (ELISA). The results showed that in the normal group, NF-kappaB and IFN-gamma were weakly expressed and IL-10 was strongly expressed in the endometrium during the whole implantation period. In the model group, the expressions of NF-kappaB and IFN-gamma were increased on pregnancy day 5, 6 and 7, and IL-10 expression decreased during the whole implantation time when compared with those in the normal group (P<0.01 for all). In the Bangdeyun-treated group, little amount of NF-kappaB and IFN-gamma was expressed and IL-10 expression was strong, much the way they were expressed in the normal group (P>0.05). The expressions of NF-kappaB and IFN-gamma were much lower in the Bangdeyun-treated group than those in the model group on pregnancy day 5, 6 and 7 (P<0.01 for all), while the expression of IL-10 was much higher than in the model group during the whole implantation time (P<0.01). It was suggested Bangderun may favor a shift from Th1- to Th2-type immune response, therefore inhibiting the maternal immune rejection, inducing the immune tolerance and improving the fetal implantation.

In a dot Hot using the McAb B10, less than 0.05 pg of sulfonated DNA could be detected while 10 ng of DNA was not coloured The result showed that the sensitivity of McAb B10 was higher than that of the McAb from "Chemiprobe" kit

Objective To build an antibody microarray based on direct labeling strategy for microalbnrninuria measurement, and evaluate it's technical potentiality for clinical application. Methods Urine samples of diabetic patients were collected. Antibody microarrays were constructed by preparation of array support, array fabrication, then protein assay and data analysis were performed. Procedure conditions for each step especially the labeling of samples were optimized. The set-ups were evaluated in terms of sensitivity, specificity and reproducibility. Urinary albumin excretion in the samples was detected by fabricated protein array, which was compared to that detected with immunoturbidimetry. Results The signal intensity was best when protein quality ratio of pure albumin or urine sample against NHS-biotin was 2:1. A calibration curve with a correlation coefficient of 0.9995 was established. The lower limit of detection was 0.0617 mg/L. Interehip and intrachip variation studies conducted on patient urine demonstrated CVs as 6.78%-9.22% and 3.35%-7.59%, respectively. Compared with the immunoturbidimetry, the antibody microarray was able to detect the extremely lower grade albumin in urine samples. The correlation coefficient of the results obtained by the two methods was 0.9199 (P <0.01). Conclusion An antibody microarray based on direct labeling strategy for microalbuminuria measurement is successfully established, which is comparable to immunoturbidimctry in its accuracy and will have great potential for clinical use with its high throughput, sensitivity, specifity and reproducibility.

Conclusion NS4B could play a role in persistence and resistance to IFN therapy in HCV infection.

OBJECTIVE: To evaluate the anxiety and depression status of patients with nasal septum deviation before and after surgery, and explore the relationship between anxiety and depression and nasal symptoms. METHOD: By means of visual analogue scale (VAS) as the evaluation index of quality of life, self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to analyze statuses before and after surgery. The 98 patients with nasal septum deviation were collected. RESULT: The preoperative SAS/SDS scores of the nasal septum deviation patients were higher than those of the national standards. The level of anxiety and depression were lower than the national norm after treatment. The patients of the normal and moderate SAS/SDS scores felt better after surgery. The patients of the severe SAS/SDS scores felt the symptoms improve poor. CONCLUSION Doctors should pay attention to the application of the SAS/SDS in patients of nasal septum deviation. Surgeon should actively communicate with severe patients in psychological problems, and strictly control the surgical indication of such patients.

OBJECTIVETo determine expression changes of major outer membrane protein(OMP) antigens of Leptospira interrogans serogroup Icterohaemorrhagiae serovar Lai strain Lai during infection of human macrophages and its mechanism.

METHODSOmpR encoding genes and OmpR-related histidine kinase (HK) encoding gene of L.interrogans strain Lai and their functional domains were predicted using bioinformatics technique. mRNA level changes of the leptospiral major OMP-encoding genes before and after infection of human THP-1 macrophages were detected by real-time fluorescence quantitative RT-PCR. Effects of the OmpR-encoding genes and HK-encoding gene on the expression of leptospiral OMPs during infection were determined by HK-peptide antiserum block assay and closantel inhibitive assays.

RESULTSThe bioinformatics analysis indicated that LB015 and LB333 were referred to OmpR-encoding genes of the spirochete, while LB014 might act as a OmpR-related HK-encoding gene. After the spirochete infecting THP-1 cells, mRNA levels of leptospiral lipL21, lipL32 and lipL41 genes were rapidly and persistently down-regulated (P <0.01), whereas mRNA levels of leptospiral groEL, mce, loa22 and ligB genes were rapidly but transiently up-regulated (P<0.01). The treatment with closantel and HK-peptide antiserum partly reversed the infection-based down-regulated mRNA levels of lipL21 and lipL48 genes (P <0.01). Moreover, closantel caused a decrease of the infection-based up-regulated mRNA levels of groEL, mce, loa22 and ligB genes (P <0.01).

CONCLUSIONExpression levels of L.interrogans strain Lai major OMP antigens present notable changes during infection of human macrophages. There is a group of OmpR-and HK-encoding genes which may play a major role in down-regulation of expression levels of partial OMP antigens during infection.

Objective: To investigate the value of initial CT quantitative analysis of ground-glass opacity (GGO), consolidation, and total lesion volume and its relationship with clinical features for assessing the severity of coronavirus disease 2019 (COVID-19). Materials and Methods: A total of 84 patients with COVID-19 were retrospectively reviewed from January 23, 2020 to February 19, 2020. Patients were divided into two groups: severe group (n = 23) and non-severe group (n = 61). Clinical symptoms, laboratory data, and CT findings on admission were analyzed. CT quantitative parameters, including GGO, consolidation, total lesion score, percentage GGO, and percentage consolidation (both relative to total lesion volume) were calculated. Relationships between the CT findings and laboratory data were estimated. Finally, a discrimination model was established to assess the severity of COVID-19. Results: Patients in the severe group had higher baseline neutrophil percentage, increased high-sensitivity C-reactive protein (hs-CRP) and procalcitonin levels, and lower baseline lymphocyte count and lymphocyte percentage (p < 0.001). The severe group also had higher GGO score (p < 0.001), consolidation score (p < 0.001), total lesion score (p < 0.001), and percentage consolidation (p = 0.002), but had a lower percentage GGO (p = 0.008). These CT quantitative parameters were significantly correlated with laboratory inflammatory marker levels, including neutrophil percentage, lymphocyte count, lymphocyte percentage, hs-CRP level, and procalcitonin level (p < 0.05). The total lesion score demonstrated the best performance when the data cut-off was 8.2%. Furthermore, the area under the curve, sensitivity, and specificity were 93.8% (confidence interval [CI]: 86.8–100%), 91.3% (CI: 69.6–100%), and 91.8% (CI: 23.0–98.4%), respectively. Conclusion CT quantitative parameters showed strong correlations with laboratory inflammatory markers, suggesting that CT quantitative analysis might be an effective and important method for assessing the severity of COVID-19, and may provide additional guidance for planning clinical treatment strategies.
