Objective To analyze the efficacy of the combination of MALDI-TOF and immunoadsorption to detect new biomarkers for lupus. Methods Twenty lupus patients at active stage (SLE group), 10 SLE patients in remission (SLE control group), 10 RA patients and 10 PSS patients (other rheumatic disease control group) and 20 healthy volunteers (healthy control group) were enrolled. The serum samples before and after immunoadsorption from SLE group and those from the control groups were co-incubated with activated chitosan copper derivative nano material. The adsorbed nano material was spotted onto the matrix used in MALDI-TOF for analysis by the Axima-CFR plus MALDI-TOF mass spectrometer. T-test was used for statistical analysis. Results MALDI-TOF MS screening showed that three potential protein biomarkers of mass-to-charge (m/z) ratio 3136, 3264, 3326 were found to be very specific for lupus patients: All of them were expressed before immunoadsorption in high quantity and none of them could be detected both after immunoadsorption and in all the three control groups. None of them (<10 000) were in the molecular weight range of the biomarkers used nowadays such as auto antibodies and complement (>50 000). Conclusion The combination of MALDI-TOF and immunoadsorption is effective in the detection of new serum protein biomarkers for lupus and it may be helpful in the screening of SLE patients at active stage from healthy people.

Objective:To explore the application situation and hotspots of the Q method in the field of nursing research and provide a reference for the nursing workers in China to learn and apply the Q method.Methods:Literature retrieval was conducted based on Web of Science, and statistical analysis was conducted on the number of articles published, countries, journals, institutions, authors, highly cited papers, research directions and high-frequency co-occurrence words by using the analysis function of Web of Science and visual imaging of VOSviewer.Results:A total of 686 authors from 25 countries and 23 institutions published 326 papers in 157 journals applying the Q method in nursing research, showing an overall increasing trend. South Korea (12.27%) , the United States (7.98%) , the United Kingdom (7.06%) ranked the highest number of articles published, and China ranked the sixth (3.68%) The number of citations per article was the highest in the United Kingdom (33.78 times) , followed by Canada (19.67 times) . Psychology and health care were the most interdisciplinary subjects. The research hotspots expanded from methodological discussions to nursing education, clinical practice, psychological nursing and health promotion.Conclusions:Q method is still in its infancy in the field of nursing in China and has not been widely promoted and practiced. China's publication volume and influence are relatively weak. In the future, international exchanges and cooperation should be expanded and academic frontiers and research hotspots should be grasped to improve the level and quality of research.

Objective To investigate the expression and significance of microtubule-associated protein 1 light chain 3 (LC3), an autophagy marker protein, in ameloblastomas. Methods Immunohistochemical methods were employed to evaluate the expression of LC3 in104 cases of ameloblastomas and 20 cases of normal oral mucosal tissues. The results were analyzed by a semiquantitative analysis method. Results The reactivity of LC3 in the epithelial cells of ameloblastomas was positive, and the positivity rate was significantly higher than that in normal oral mucosal tissues (P < 0.05). There were no significant differences between the LC3 expression levels with respect to age, gender, or recurrence (P < 0.05). The positivity rate in mandible ameloblastomas was significantly higher than that in maxilla and gingiva ameloblastomas (P < 0.05). The reactivity for LC3 was significantly higher in solid ameloblastomas than that in the other three tissue types (P < 0.05). Conclusion Autophagic activity in ameloblastomas was higher than that in normal oral mucosal tissues. This suggests that autophagy plays an important role during tumorigenesis, and contributes to the local invasion of ameloblastomas.

Objective To investigate the expression characteristics of S100 calcium binding protein P(Sl00P)and thymic stromal lymphopoietin(TSLP)in patients with breast cancer and their relationship with prognosis.Methods GEPIA database and bc-GenExMiner v4.3 were used to analyze the expression levels of S100P and TSLP in breast cancer tissues,and Kaplan-Meier Plotter was used to analyze effects of S100P and TSLP on patient prognosis.The protein interaction network analysis of S100P and TSLP were carried out by using STRING database.The co-expressed genes of S100P and TSLP were analyzed using Linked Omics database,and the role of S100P and TSLP co-expressed genes in related biological processes and signaling pathways were evaluated by gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis.The correlation between S100P and TSLP and breast cancer immunoinfiltration was analyzed by TIMER.Results The expression of S100P in breast cancer patients was significantly higher than that in normal population,and the expression of TSLP was significantly lower than that in normal population(P<0.05).The overall survival,disease-free survival and distant metastasis-free survival of patients with high S100P expression were significantly shorter than those of patients with low S100P expression(P<0.05).The distant metastasis-free survival of patients with high expression of TSLP was significantly longer than that of patients with low expression of TSLP(P<0.05).The results of protein interaction showed that S100P had a strong interaction with interleukin-11,and TSLP had a strong interaction with interleukin family proteins.The co-expressed genes of S100P and TSLP were mainly responsible for biological functions such as DNA replication and immune function.TSLP was correlated with breast cancer immune cell infiltration.Conclusion S100P and TSLP can be used as biomarkers to predict the prognosis of breast cancer,and they can also help to evaluate the tumor immunoinfiltration in breast cancer patients,and TSLP could provide theoretical basis for predicting the prognosis and tumor immunotherapy in breast cancer patients.

This paper aimed to explain the clinical thinking of using the method of unblocking the bowels and harmonizing viscera. Based on theory of "viscera-bowels extraordinary connection" of The Gateway to Medicine (《医学入门》), combined with the theoretical research, clinical practice and individual experience of ancient physicians, modern scholars, it is believed that viscera qi disorder caused by bowels qi blocking is the basic mechanism of insomnia. In clinic, it is common that gallbladder phlegm-heat harassing the heart spirit, stagnant blood and qi in stomach blocking the pericardium, turbid heat in large intestine causing fire and affecting liver, dampness insmall intestine trapping the spleen, water retention in the bladder drying up lungs, and the inhibited original qi of sanjiao damaging the kidney, which could be treated with Wendan Decoction (温胆汤), Taohe Chengqi Decoction (桃核承气汤), Chengqi-series Decoction (承气汤类方), Linggui Zhugan Decoction (苓桂术甘汤), Wuling Powder (五苓散), Xiaochaihu Decoction (小柴胡汤), respectively.
