Objective To clone and bioinformatically analyze the full-length sequence of F protein binding protein 1 (FBP1). Methods Yeast two-hybrid system was employed to obtain an unknown gene and named it as FBP1.The coding sequence of FBP1 was cloned using molecular biological techniques. Results The coding sequence of FBP1 was cloned successfully. Conclusion FBP1, a cellular protein binding to F protein of HCV, plays an important role in the interaction of virus protein and host cell protein.

OBJECTIVEThe study investigated the epidemiology of Filifactor alocis (F. alocis) in subgingival plaque samples from subjects with different periodontal statuses. The relationship between the prevalence of F. alocis and clinical periodontal parameters was also analyzed.

METHODSSubgingival plaque samples and periodontal data were collected from 68 healthy sites (H groups) in 17 healthy subjects, 64 healthy (G-H group) and 76 diseased sites (G-D group) in 19 patients with chronic gingivitis, and 36 healthy (P-H group) and 56 diseased sites (P-D group) in 14 patients with chronic periodontitis. The plaque samples were analyzed by polymerase chain reaction, and possible correlations between the F. alocis detection rate and the bleeding index, probing depth, or clinical attachment level were determined.

RESULTSThe detection levels of F. alocis increased in both healthy and diseased groups. The lowest level at 30.88% (21/68) was noted in the H group, whereas the highest level at 91.07% (51/56) was obtained from the P-D group. A significant correlation was found between the F. alocis detection levels and periodontal disease condition (P < 0.000 1). Further analyses showed that a significant correlation also existed between the detection level of F. alocis and the abnormal clinical periodontal parameters, namely, bleeding index, probing depth, and clinical attachment loss. The odds ratios were 5.26, 8.85, and 11.65, respectively.

CONCLUSIONF. alocis was found at increased-levels in subjects with periodontal disease. The presence of F. alocis increases the risk of sites with abnormal clinical periodontal parameters.

, 15min),the clearance of reticuloendothelial system (RES) of mice on iv charcoal particles were decreased apparently; serum hemolysin concentration were diminished notably; delayed type hypersensitivity (DTH) reaction induced by sheep red blood cell (SRBC) were inhibited obviously. Ginseng root saponins (GRS) 50, 100 mg ??? kg-1ip at 15min before the heat-stressprotected the immunity of mice from inhibitory effects induced by the heat-stressor. The suppression of the clearance of RES on charcoal particles,serum hemolysin concentration as well as DTH reaction induced by SRBC were all abolished by GRS.

Objective To assess the biophysical characteristics of normal skin and inflammatory skin lesions in mild and moderate acne. Methods Seventy-five mild and moderate acne vulgaris patients were included in the study. One inflammatory lesion measuring 2.0 to 5.0 mm in diameter which occurred within 48 hours prior to the measurement was selected as the target lesion. Trans-epidermis water loss (TEWL), capacitance and a* value were measured in target lesions and lesion-adjacent normal skin. Sebum content immediately,1 and 4 (saturated) hours after face washing was also determined on target lesions and central forehead between the eyebrows. Sebum secretion rate (SSR) was calculated. Results The TEWL and SSR significantly increased in the lesion-adjacent normal skin with the increment of inflammatory lesion number (both P < 0.05), and increased in target lesions with the elevation of a* value (both P < 0.05). The target lesions exhibited a significantly higher TEWL but a lower saturated sebum content and SSR than the adjacent normal skin did (all P <0.05). Conclusions The severity of inflammatory lesions is correlated with the impaired barrier function and increased SSR in facial skin. Compared with the adjacent normal skin, inflammatory skin lesions have a reduced skin barrier function and SSR.

Objective: To explore the relationship between family intergenerational contact, depressive symptoms and self-rated health status in the elderly, so as to provide insights into promoting health of the elderly and actively coping with population aging. Methods: Demographic information, intergenerational contact frequency, self-rated health status and depressive symptoms in the elderly at ages of 65 years and older were collected through the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Structural equation model was established to analyze the effects of intergenerational contact on self-rated health and the mediating role of depressive symptoms between family intergenerational contact and self-rated health in the elderly. Results: Totally 15 497 elderly participants were enrolled, with 6 727 males (43.41%) and 8 770 females (56.59%), and there 12 583 individuals lived with family members (81.19%). The median age was 85.00 (interquartile range, 16.00) years. The scores of self-rated health and depressive symptoms were (3.39±0.87) and (2.22±0.56), respectively. The results of structural equation model analysis showed that after adjusting for age, gender and residence, frequent intergenerational contact had a direct positive effect on self-rated health (effect size=0.038, P<0.001), and could improve the depressive symptoms (effect size=0.089, P<0.001) in the elderly. In addition, depressive symptoms had a negative effect on self-rated health in the elderly (effect size=-0.422, P<0.001). Conclusions Frequent intergenerational contact can improve the self-rated health status in the elderly, and indirectly improve the self-rated health level by alleviating depressive symptoms.

Objective:To evaluate the prediction value of preoperative Fibrinogen(FIB) in combination with neutrophil-lymphocyte ratio(NLR)for the prognosis of operable pancreatic cancer patients.Methods:The clinical data of 124 patients who underwent radical resection for pancreatic cancer in our hospital from Jan 2010 to Dec 2018 were retrospectively analyzed.The patients were divided into three groups according the high and low NLR, FIB value which defined by the receiver operating characteristic curve (ROC). The clinicopathological data and overall median survival time were compared between the three groups.Results:Univarate analysis showed that age, tumor stage, NLR, FIB and F-NLR score were associated with the prognosis( P<0.05), while multivariate analysis showed that high F-NLR score was the independent prognostic factor. The median survival time of patients with F-NLR scores 0, 1 and 2 group was 30.6, 20.3 and 13.9 months( P<0.05). The prognosis of high F-NLR score was significantly worse than that of low F-NLR score( P<0.05). Conclusions:A high preoperative F-NLR score was a promising predictor for the prognosis of pancreatic cancer patients after radical resection.
