Abstract	Abstract Purpose To investigate underlying co-mechanisms of PCOS and periodontitis through transcriptomic approach. Methods PCOS and periodontitis gene expression data were downloaded from the GEO database to identify differentially expressed genes. GO and KEGG pathway enrichment analysis and random forest algorithm were used to screen hub genes. GSEA analyzed the functions of hub genes. Correlations between hub genes and immune infiltration in two diseases were examined, constructing a TF-ceRNA regulatory network. Clinical samples were gathered from PCOS and periodontitis patients and RT-qPCR was performed to verify the connection. Results There were 1661 DEGs in PCOS and 701 DEGs in periodontitis. 66 intersected genes were involved and were enriched in immune and inflammation-related biological pathways. 40 common genes were selected from the PPI network. RF algorithm demonstrated that ACSL5, NLRP12, CCRL2, and CEACAM3 were hub genes, and GSEA results revealed their close relationship with antigen processing and presentation, and chemokine signaling pathway. RT-qPCR results confirmed the upregulated gene expression in both PCOS and periodontitis. Conclusion The 4 hub genes ACSL5, NLRP12, CCRL2, and CEACAM3 may be diagnostic genes for PCOS and periodontitis. The created ceRNA network could provide a molecular basis for future studies on the association between PCOS and periodontitis.

Abstract	Abstract Background Standardized residency training (SRT) is crucial for graduate medical education and the training of high-quality doctors. Nevertheless, China started SRT nationwide only in the recent decade. During these years, researchers have been searching for suitable teaching methods to improve the abilities of residents. Although the problem-based learning (PBL) teaching mode has been applied in undergraduate teaching for many years, the teaching effect of PBL has not been unified in Chinese SRT according to the core competences of the residents. Methods Studies that compared the teaching effect of PBL and lecture-based learning (LBL) on SRT in China from January 2010 to April 2020 in the Chinese databases, such as China National Knowledge Infrastructure (CNKI), WanFang, WeiPu, Chinese BioMedical Literature (CBM), and English-language online databases, such as PubMed, Embase, and Cochrane Library were systematically reviewed. Data were analyzed using the Stata version 12.0 software. Results A total of 75 articles (76 studies) were included in this meta-analysis. Compared with LBL group, PBL-based methods are more effective in the mastery of medical theory knowledge (WMD = 7.14, 95% CI: 5.93–8.34), operational skills (WMD = 6.54, 95% CI: 4.55–8.53), analysis and diagnosis of cases (WMD = 8.52, 95% CI: 7.50–9.53), and overall capacity (WMD = 8.70, 95% CI: 6.87–10.53), but showed no advantage on operational skills in diagnostic imaging (WMD = 1.30, 95% CI: -0.11–2.71). The questionnaire surveys analyzed in this meta-analysis indicated the positive effects of PBL on the mastery of theoretical knowledge, clinical diagnostic thinking, teamwork ability, ability to analyze and solve problems, ability to consult documents, learning interest and learning efficiency, but that there were no advantages in improving self-directed learning ability, communication ability and hands-on ability. The questionnaire result analyzed in this meta-analysis also showed the residents’ satisfaction with PBL-based strategies. ...

Abstract	Preeclampsia (PE) is a complex pregnancy syndrome. Convincing evidence indicates that long non-coding RNAs (lncRNAs) are involved in the pathogenesis of PE. This research mainly investigated the mechanism of family with sequence similarity 99 member A (FAM99A) in PE. The expressions of FAM99A, miR-134-5p, and YAP1 were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Cell apoptosis, migration, and invasion were detected by flow cytometry or transwell assay. The interaction between miR-134-5p and FAM99A or YAP1 was confirmed by dual-luciferase reporter assay. The protein expression of YAP1 was determined by western blot assay. FAM99A and YAP1 were significantly up-regulated, and miR-134-5p was significantly down-regulated in PE tissues (n=30). miR-134-5p was verified as a candidate of FAM99A and YAP1. FAM99A promoted cell metastasis, but reduced apoptosis in HTR8/SVneo cells by regulating miR-134-5p. miR-134-5p down-regulated YAP1 expression to suppress cell metastasis, while it induced apoptosis in HTR8/SVneo cells. FAM99A positively modulated YAP1 expression by sponging miR-134-5p. FAM99A modulated YAP1 to accelerate cell migration and invasion, and inhibited cell apoptosis in PE cells by sponging miR-134-5p. The novel regulatory network may shed light on the pathogenesis of PE.

Abstract	Background: The purpose of this study was to systematically evaluate the effect of renin–angiotensin–aldosterone system blockers on the incidence of contrast-induced nephropathy in patients undergoing coronary angiography or percutaneous coronary intervention. Methods: A systematic literature search of several databases was conducted to identify studies that met the inclusion criteria. A total of 12 studies with 14 trials that performed studies on a total of 4864 patients (2484 treated with renin–angiotensin–aldosterone system blockers and 2380 in the control group) were included. The primary endpoint was the overall incidence of contrast-induced nephropathy. Analyses were performed with STATA version 12.0. Results: The overall contrast-induced nephropathy incidence in renin–angiotensin–aldosterone system blocker and control groups was 10.43% and 6.81%, respectively. The pooled relative risk of contrast-induced nephropathy incidence was 1.22 (95% confidence interval: 0.81–1.84) in the renin–angiotensin–aldosterone system blocker group. An increased risk of developing contrast-induced nephropathy in the renin–angiotensin–aldosterone system blocker group was observed among older people, non-Asians, chronic users, and studies with larger sample size, and the pooled RRs and 95% confidence intervals were 2.02 (1.21–3.36), 2.30 (1.41–3.76), 1.69 (1.10–2.59) and 1.83 (1.28–2.63), respectively. Conclusions: Intervention with renin–angiotensin–aldosterone system blockers was associated with an increased risk of contrast-induced nephropathy among non-Asians, chronic users, older people, and studies with larger sample size. Large clinical trials with strict inclusion criteria are needed to confirm our results and to evaluate the effect further.

Abstract	Objectives: Peripheral skeletal muscle dysfunction is an important extrapulmonary manifestation of chronic obstructive pulmonary disease (COPD) that can be counteracted by exercise training. This study aimed to review the effect of three major exercise training modalities, which are used in pulmonary rehabilitation to improve on skeletal muscle mass, function, and exercise capacity in COPD.Methods: PubMed, Embase, EBSCO, Web of Science, and the PEDro database were searched on April 25, 2020. Only randomized controlled studies published in English evaluating the effects of exercise interventions on peripheral skeletal muscle mass, strength, and exercise capacity in stable COPD patients were included. The quality of included studies was evaluated using the PEDro scale. The mean difference (MD) or the standardized mean difference (SMD) with 95% CI was calculated to summarize the results. Subgroup meta-analysis was used to investigate the effects of different exercise training modalities and different outcome measures. The Grading of Recommendations Assessment, Development, and Evaluation guidelines were used to rate evidence quality.Results: A total of 30 randomized controlled trials involving 1,317 participants were included. Data from trials investigating endurance exercise (EE), resistance exercise (RE), and combined aerobic and resistance exercise (CE) were pooled into a meta-analysis, and the differences compared with the non-exercising COPD control were improvement in the muscle strength and exercise capacity in stable COPD patients. Subgroup meta-analysis for different exercise training modalities showed that RE significantly improved muscle strength (SMD = 0.6, 95% CI 0.35–0.84, I2 = 61%), EE and CE significantly increased VO2peak (EE: MD = 3.5, 95% CI 1.1–5.91, I2 = 92%; CE: MD = 1.66, 95% CI 0.22–3.1, I2 = 1%). Subgroup meta-analysis for different outcome measures showed that only isotonic strength was improved after exercise interventions (SMD = 0.89, 95% CI 0.51–1.26, I2 = 71%).Conclusion: Moderate ...

Abstract	Background: Oral lichen planus (OLP) is a common chronic inflammatory disease of the oral mucosa and considered a potential malignant disease, for which a method for complete cure is lacking. The dexamethasone and gentamicin mouthwash, combined with total glucosides of paeony (TGP), was tested in the treatment of OLP patients without fungal infection, with a view to provide evidence that may assist in resolving the dilemma. Methods: A randomized and single-blind clinical trial of 48 non-erosive and erosive OLP patients was conducted, with the patients divided into two groups. Group A was treated with dexamethasone plus gentamycin mouthwash and Group B received an additional TGP capsule together with the aforementioned mouthwash. All the patients were followed up with four times, at 2 weeks, 1 month, 3 months, and 6 months. The clinical manifestations, sign score, and VAS scale were recorded. The total effective rate (%) was defined as (cases of complete resolution + cases of partial resolution)/total cases observed × 100%. Results: A total of 43 patients completed all follow-up appointments. Among the 21 patients in Group A, the total effective rate was 61.9%. Of the 22 patients in Group B, the total effective rate was 89.66%. The clinical manifestation, sign score, and VAS of the two groups all indicated improvements, and there were significant differences between the two groups ( p < 0.05). Conclusions: Dexamethasone plus gentamycin mouthwash combined with TGP treatment for OLP patients is a safe and effective treatment of OLP.

Abstract	Introduction: Negative symptoms and cognitive impairment are common residual symptoms of schizophrenia that seriously affect the quality of life and social function of patients. The intervention of residual symptoms is an important part of schizophrenia rehabilitation. Traditional Chinese exercise has been applied as a supplementary rehabilitation method for schizophrenia. However, research on its use and pertinence in the rehabilitation of residual symptoms remains lacking. In this study, we will verify the intervention effect of a new method, namely, shen-based qigong exercise, on the residual symptoms of schizophrenia, in the hopes of finding a safe and effective rehabilitation method for the residual symptoms of schizophrenia. Methods: This is a single-centre randomised controlled trial. A total of 60 schizophrenics who meet the criteria will be randomly divided into the control and intervention groups in accordance with the ratio of 1:1. Conventional drug treatment will remain unchanged in both groups. In this case, the control group will be given daily rehabilitation, whereas the intervention group will be given daily rehabilitation and shen-based qigong exercise intervention. The intervention period will be 12 weeks. The primary outcome will be negative symptoms assessed by the Scale for the Assessment of Negative Symptoms. The secondary outcome will be the global cognitive function assessed by the Repeatable Battery for the Assessment of Neuropsychological Status and event-related potential P300. Other outcomes will include specific cognitive domain (i.e. working memory), quality of life and social function. The results will be measured within 1 week before and after the intervention. Discussion: The results of this study will likely help find an economical and convenient rehabilitation method for the residual symptoms of schizophrenia and, at the same time, may promote the popularisation and application of traditional Chinese exercises and traditional Chinese medicine theories in the treatment of mental ...

Abstract	Background Medullary thyroid carcinoma (MTC) is an infrequent form malignant tumor with a poor prognosis. Because of the influence of competitive risk, there may suffer from bias in the analysis of prognostic factors of MTC. Methods By extracting the data of patients diagnosed with MTC registered in the Surveillance, Epidemiology, and End Results (SEER) database from 1998 to 2016, we established the Cox proportional-hazards and competing-risks model to retrospectively analyze the impact of related factors on lymph nodes statistically. Results A total of 2,435 patients were included in the analysis, of which 198 died of MTC. The results of the multifactor competing-risk model showed that the number of total lymph nodes (19-89), positive lymph nodes (1-10,11-75) and positive lymph node ratio (25%-53%,>54%), age (46-60,>61), chemotherapy, mode of radiotherapy (others), tumor size(2-4cm,>4cm), number of lesions greater than 1 were poor prognostic factors for MTC. For the number of total lymph nodes, unlike the multivariate Cox proportional-hazards model results, we found that it became an independent risk factor after excluding competitive risk factors. Competitive risk factors have little effect on the number of positive lymph nodes. For the proportion of positive lymph nodes, we found that after excluding competitive risk factors, the Cox proportional-hazards model overestimates its impact on prognosis. The competitive risk model is often more accurate in analyzing the effects of prognostic factors. Conclusions After excluding the competitive risk, the number of lymph nodes, the number of positive and the positive proportion are the poor prognostic factors of medullary thyroid cancer, which can help clinicians more accurately evaluate the prognosis of patients with medullary thyroid cancer and provide a reference for treatment decision-making.

Abstract	This paper attempts to overcome the inefficiency of covariance model (CM) in the search for non-coding sequence. For this purpose, the members of non-coding RNA family were compared and the CM of the family was discussed in details. Next, the CM was improved for structural units in the secondary structure, through the addition of the upper and lower limits on subsequence length. Based on the length distribution of each structural unit, the improved model limits the number of insertions and deletions during the evolution of sequences in the same family. After that, the author put forward a novel non-coding RNA sequence alignment algorithm. The experimental results show that the proposed algorithm can greatly reduce the computing time of non-coding RNA sequence comparison.

Abstract	Introduction Cognitive impairment, an important complication in patients with chronic obstructive pulmonary disease (COPD), seriously affects self-management of the disease and quality of life (QoL). As an exercise-based intervention programme, pulmonary rehabilitation (PR)—especially aerobic exercise (mainly mind–body exercise) and resistance exercise (RE)—has been proposed for its potential effectiveness in improving cognitive function. However, there is still a lack of strong evidence for PR’s effectiveness. In this study, we expect to clarify the effects of pulmonary-based Qigong exercise and elastic band-based RE on cognitive function in patients with COPD and to fill in the relevant evidence blanks.Methods and analysis This study is a single-centre randomised controlled trial with assessor and data analyst blinding. We will recruit 108 participants with stable COPD starting on 23 December 2019, and randomly allocate them into the pulmonary-based Qigong exercise group, elastic band-based RE group, pulmonary-based Qigong exercise and elastic band-based RE combined group, or control group at a 1:1:1:1 ratio. Participants in intervention groups will perform 30 min of exercise two times per day, 5 days a week, for 12 weeks. The primary outcome will be the global cognitive function as assessed by the Montreal Cognitive Assessment and auditory event-related potential P300. Secondary outcomes will include the specific cognitive domains—attention, memory, executive function, verbal fluency and mental-processing speed; psychological functions and QoL. Exploratory outcomes will include grey matter volume and levels of inflammatory mediators. Outcomes will be measured before and after the interventions.Ethics and dissemination Ethics approval has been granted by the Ethics Committee of Yue-Yang Integrative Medicine Hospital, an affiliate of Shanghai University of Traditional Chinese Medicine, Shanghai, China (Grant No. 2019-141). Written informed consent will be obtained from each participant before any procedures are ...
