The detection rate of streptococcus oralis, lactobacillus,fusobacterium nucleatum,black-pigment bacteria,Capnocytophaga gingivalis,actinomycetes, escherichia coli,staphylococcus aureus and pseudomonas aeruginosa had no significant differences,there was a positive correlation between quantity of black-pigment bacteria, Capnocytophaga gingivalis and fasting blood glucose and glycosylated hemoglobin of patients with diabetic ketoacidosis. Conclusions Diabetic ketoacidosis strengthened the bacterial invasion and oral colonization of patients.

OBJECTIVETo investigate the effects of Newcastle disease virus (NDV) infection on the expression of survivin and cell cycle in human tongue squamous carcinoma TSCCa cells.

METHODSThe proliferation of TSCCa cells infected with NDV in vitro was evaluated by means of MTT assay, and survivin expression in the infected cells was detected using RT-PCR and Western blotting. Flow cytometry was performed to assess the changes in the cell apoptosis, cell cycle and cell proliferation index (PI) of the cells.

RESULTSNDV infection resulted in decreased survivin expression and increased apoptosis of TSCCa cells, with reduced cell percentage in G2/M and S phases and lowered PI of the cells, showing significant differences from those of the negative control cells (P<0.05).

CONCLUSIONNDV infection can inhibit survivin expression, affect the cell cycle of TSCCa cells and induce their apoptosis.

The objective of the study is to find out the effect of shark chondroitin on T lymphocyte subsets in cancer patients. Patients were divided into two groups. One group was treated with chemotherapy alone, and the other group was treated with chemotherapy plus shark chondroitin. Using immunofluorescence technique, T lymphocyte subsets in the peripheral blood were determined in two groups before and after chemotherapy. The results showed that CD4(+)/CD8(+) ratio increased in the patients received shark chondroitin. In the chemotherapy group, CD3(+) had no change, but CD4(+) decreased while CD8(+) increased significantly. The results suggest that shark chondroitin could enhance immune function in cancer patients, especially during chemotherapy.

Dissolved organic matter (DOM) is the most active fraction of compost organic matter. The presence of the redox-active functional groups in DOM allows it to act an electron shuttle to promote the electron transfer between microorganisms and terminal electron acceptors. In this study, the electron transfer capacities (ETCs) of compost DOM samples at eight different composting stages were determined by electrochemical method. The 2, 2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and Diquat dibro-mide monohydrate (DQ) were used to measured electron donating capacity (EDC) and electron accepting capacity(EAC) with working voltage 0.61 V/-0.49 V,respective. The evolution characteristics of the chemical structures and components were analyzed by combining the three-dimensional fluorescence spectra,fourier transform infrared (FTIR) spectra and elemental analysis. The results showed that the electron donating capacity(EDC) of DOMincreased from 16.850 μmol e-/(g C) to 22.077 μmol e-/(g C), The corresponding electron accepting capacity (EAC) decreased from 1.866 μmol e-/(g C)to 1.779 μmol e-/(g C). The results of three-dimensional fluorescence spectroscopy show that the relative contents of humuc-likeand protein-like components gradually increased and decreased, respectively, during the composting process. The humuc-like components were the main contributor for the ETC of DOM. FTIR spectra shows that there was no significant change in the hydroxyl and carboxyl group contentsof DOM during composting, suggesting no contribution of these function groups to the ETC of DOM. The elemental analysis showed that the content of oxygen in the DOM increased during the composting process, while the sulfur-containing group may be dominated contributor forits ETC.

Objective: To explore the value of baseline geriatric nutritional risk index (GNRI) in evaluating the prognosis of patients with end-stage renal disease (ESRD) who underwent peritoneal dialysis (PD). Methods: The clinical data of patients who underwent PD catheterization and started PD therapy at the First Affiliated Hospital of Zhengzhou University from January 1, 2013 to December 30, 2018 were collected retrospectively. The follow-up endpoint was death or hemodialysis. The follow-up deadline was March 1, 2019. The GNRI cut-off value was determined according to the ROC curve, and the patients were divided into GNRI≤90.5 group and GNRI>90.5 group. The differences of clinical data and laboratory tests were compared between the two groups. Kaplan-Meier survival curves were used to compare the difference in PD rate between the two groups during follow-up, and the factors that affecting patients PD withdrawal were analyzed by Cox regression. Results: The GNRI cut-off value was determined to be 90.5 based on the ROC curve. Until the deadline for follow-up, the drop-out rate of GNRI≤90.5 group was significantly higher than the GNRI>90.5 group (35.88% vs 21.58%, P=0.003). Kaplan-Meier survival curves showed a higher rate of maintaining PD in the GNRI>90.5 group than that in GNRI≤90.5 group during follow-up (P=0.021). Cox univariate regression showed that male, GNRI and serum Alb were protective factors for PD patients, and Scr was a risk factor. After multiple factors correction, male and GNRI were also the protective factors for PD patients. Conclusion As an objective indicator of nutritional evaluation, baseline GNRI can be used as a prognostic indicator for PD patients.

Objective:To explore the research hotspots and evolution of Common Sense Model (CSM) , in order to provide a clearer research direction for nursing workers to improve health-related outcomes of patients from the perspective of health psychology.Methods:English literature related to CSM was searched in Web of Science Core Collection database from January 1, 1985 to December 31, 2020. VOSviewer 1.6.15 software was used to draw a visual map of keyword density, clustering and time distribution and CiteSpace 5.6.R5 software was used to detect emerging words.Results:Finally, 364 papers were included, and the annual publication volume and citation frequency of CSM research showed an overall upward trend. CSM research hotspots mainly focused on interpreting or intervening patients' perception of disease, in order to improve self-management of patients, compliance, quality of life, anxiety, depression and psychological distress. The research objects were mainly cancer patients. Social support and psychological distress were explored based on the CSM framework and using Meta-analysis methods to summarize may be an important part of future CSM research work. CSM research was currently in the stage of summarizing and deepening after theoretical perfection and extensive application.Conclusions:The annual publication volume and citation frequency of CSM research have generally shown an upward trend, which has attracted the attention of domestic scholars, but there is still a big gap compared with foreign countries. Future research can explore the role of social support in the process of individual self-regulation after illness and explore effective methods to intervene in patients' negative disease perception through Meta-analysis, in order to improve patients' health outcomes.

Objective:To observe the effect of curricular reforms of physical medicine and rehabilitation in medical engineering interdisciplinary on learning of eight-year medical students. Methods:The eight-year medical students studying Physical Medicine and Rehabilitation in Tsinghua University in 2018 and 2019 were enrolled into control group (n = 20) and observation group (n = 18), respectively. The control group used routine courses and studied with teachers of rehabilitation medicine; while the observation group added neuroscience theory and new advances, the development of functional magnetic resonance and application in rehabilitation medicine, new technology and progress in medical engineering in the course, and studied with teachers of electronic engineering, mechanical engineering and medicine. Their performances were compared. The observation group was surveyed with self-designed questionaire. Results:The performance of paper test, general test and total test were higher in the observation group than in the control group (t > 2.694, P < 0.01). The questionnaire showed that the observation group could better understand the course of Physical Medicine and Rehabilitation and the development of medical engineering interdisciplinary crossing and translational research within physical medicine and rehabilitation, and they thought it was more necessary to study the new course after the curriculum finished (|Z| > 2.304, P < 0.05). The proportion of students who were interested and very interested in medical engineering interdisciplinary crossing and translational research within physical medicine and rehabilitation increased from 77.78% to 94.44% (P = 0.222), and the the proportion of students who were probably and very probably engaged in physical medicine and rehabilitation increased from 61.11% to 83.33% (P =0.043). Conclusion:The curricular reforms in medical engineering interdisciplinary crossing could raise the interest and improve the test performance of eight-year students with physical medicine and rehabilitation.

Objective:To explore the factors affecting curative effect of motor imagery brain-computer interface (MI-BCI) training on upper limb paralysis for subacute stroke patients. Methods:From January, 2018 to July, 2019, 23 inpatients with post-stroke upper limb paralysis accepting MI-BCI training were reviewed. The gender, age, course of disease, aphasia, location and nature of lesion, history of Botulinum toxin, hemisphere injured and modified Ashworth Scale (MAS) score of affected fingers were recorded, and they were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) before and four weeks after MI-BCI training. According to improvement of FMA-UE wrist and hand scores (≥ 2), the patients were divided into effective group (n = 11) and inefficacy group (n = 12). Results:The MAS scores before MI-BCI training (t = 2.677, P < 0.05) and history of botulinum toxin (Z = 0.000, P < 0.05) were more in the inefficacy group than in the efficacy group. FMA-UE scores (total and dimensions) after training were correlated to their baseline levels (r > 0.831, P < 0.01), FMA-UE total scores (Eta = 0.453, P < 0.05) and upper arms scores (Eta = 0.506, P < 0.05) were correlated to aphasia, FMA-UE scores of hands were correlated with MAS (r = -0.521, P < 0.05). Conclusion:Poor baseline motor function, spasticity and complication with aphasia were the factors unfavorable to MI-BCI training for subacute stroke patients with upper limb paralysis.
