RESUMO

BACKGROUND: Verrucous epidermal nevi (VEN) are benign skin tumors, considered keratinocytic epidermal nevi, that appear at birth or early childhood. VEN may display a range of appearances, depending on patient age. Although the number of studies regarding VEN is increasing, the exact mechanism of VEN is still unknown. OBJECTIVES: The aim of this study was to analyze the changes in the expression of protein factors in lesions of VEN children by TMT labeling-based quantitative proteomics. METHODS: A total of 8 children with VEN (5 for experiment and 3 for validation) and 8 healthy children (5 for experiment and 3 for validation) presented to the Department of Dermatology, the First Affiliated Hospital of Anhui Medical University, Boao Super Hospital, between January 2019 and November 2019. The lesions and lesion-adjacent tissues from children with VEN and nevus-adjacent normal skin tissues from children with pigmented nevi were defined as the VEN group, VENC group and C group, respectively. We performed a proteomics analysis to screen for differentially expressed proteins in the lesions of these individuals. We further performed Western blotting to validate the relative expression levels of nine targeted proteins in the validation group. RESULTS: According to the proteomics results, a total of 4,970 proteins were identified, and 4,770 proteins were quantified. Among these proteins, 586 proteins were up- or downregulated at least 1.3-fold with a P value <0.05 (upregulated: 399, downregulated: 187) in lesions between the VEN group and the C group. These proteins played important roles in multiple biological functions, such as cornification, epidermal cell differentiation, and neutrophil activation, and formed a complicated protein-protein interaction network. Of the 586 up- or downregulated proteins, nine were selected for further validation. According to Western blotting analysis results, the relative expression levels of Involucrin, NDUFA4, Loricrin, Keratin type II cytoskeletal 6A (Cytokeratin 6A), BRAF, Filaggrin, S100A7 and Desmocollin-3 were significantly upregulated in VEN children and may be associated with skin barrier dysfunction, epidermal cell overgrowth and differentiation, inflammation, and immune and oxidative phosphorylation, which are involved in the pathogenesis of VEN. CONCLUSIONS: According to TMT-based proteomics and Western blotting results, we identified eight noteworthy proteins, Involucrin, NDUFA4, Loricrin, Keratin type II cytoskeletal 6A, BRAF, Filaggrin, S100A7 and Desmocollin-3, that were upregulated in the lesions of VEN children and may be associated with the pathogenesis of VEN. Our findings provide new starting points for identifying precise pathogenic mechanisms or therapeutic targets for VEN.

RESUMO

Objective: This study aimed to examine the relationship between physical performance and mild cognitive impairment (MCI) in Chinese older adults. Methods: The sample comprised 956 relatively healthy and aged ≥65 years old Chinese community-dwelling participants (mean age, 72.56 ± 5.43 years; 56.8% female), which did not include those with dementia, severe cognitive impairment, mental illness etc. The Mini-Mental State Examination (MMSE) and the Instrumental Activities of Daily Living (IADL) scale were used for the initial classification of patients with MCI. Physical performance was measured via hand grip, Timed Up and Go Test (TUGT), and 4-m walking speed. Results: The physical performance (grip strength, TUGT, and 4-m walking speed) correlated with MCI. The grip strength [odds ratio (OR) = 0.96, 95% confidence interval (CI) = 0.93-0.99] and 4-m walking speed (OR = 0.25, 95% CI = 0.10-0.64) correlated negatively with MCI, while TUGT (OR = 1.08, 95% CI = 1.03-1.13) and MCI correlated positively. Conclusion: The physical performance (grip strength, TUGT, and 4-m walking speed) correlated with MCI. Further analysis showed that the grip strength was associated with overall cognition, time orientation, recall, and language, while TUGT and 4-m walking speed were associated with overall cognition and various cognitive domains, except recall.

RESUMO

The aim of the work described here was to evaluate the diagnostic performance of ultrasound thyroid computer-aided diagnosis (CAD) software. This multicenter prospective study included 494 patients (565 thyroid nodules) who underwent surgery or biopsy after ultrasonography at four hospitals from January 2019 to September 2019. The diagnostic performance metrics of different readers were calculated and compared with the pathologic results. The sensitivity of CAD was outstanding and was equivalent to that of a senior radiologist (90.51% vs. 88.47%, p > 0.05). The area under the curve of CAD was equivalent to that of a junior radiologist (0.748 vs. 0.739, p > 0.05). However, the specificity was only 49.63%, which was lower than those of the three radiologists (75.56%, 85.93% and 90.37% for the junior, intermediate and senior radiologists, respectively). The diagnostic performance of the junior radiologist was significantly improved with the aid of CAD (junior + CAD). The sensitivity and area under the curve of junior + CAD were improved from 72.20% to 89.93% and from 0.739 to 0.816, respectively (both p values <0.05), and the positive predictive value, negative predictive value and κ coefficient improved from 76.3% to 78.6%, 82.0% to 86.8% and 0.394 to 0.511, respectively. Though specificity slightly decreased from 75.56% to 73.33%, the difference was not statistically significant (p > 0.05). In general, the clinical application value of CAD is promising, and its instrumental value for junior radiologists is significant.

RESUMO

The removal efficiency of contaminants in large-scale integrated vertical-flow constructed wetland (IVCW) and vertical-flow constructed wetland (VCW) for wastewater treatment plant (WWTP) tail-water was evaluated, and the microbial community was also investigated in this study. The results for 14 months study period indicated that 40.05% chemical oxygen demand (COD), 45.47% ammonia nitrogen (NH4+-N), 62.55% total phosphorus (TP), 55.53% total nitrogen (TN) and 57.20% total suspended solids (TSS) average removal efficiencies were achieved in the IVCW. There was a poor performance of TN removal in the VCW, with an average removal efficiency of 38.13%. There was no significant seasonal difference in TP removal, and a strong positive correlation between influent TP load and removed load. The high-throughput sequencing analysis revealed that Proteobacteria, Planctomycetes, Bacteroidetes and Acidobacteria were dominant in nature and wetland systems. The relative abundance of nitrifying bacteria, denitrifying bacteria and anammox bacteria confirmed that nitrification, denitrification and anammox may be the main processes for nitrogen removal in the IVCW.

RESUMO

BACKGROUND: Thoracic facet joint disorder is a common thoracic disorder in clinic, inducing pain and discomfort at the dislocated thoracic vertebrae, radiating to pain of the neck and back. The incidence of thoracic facet joint disorder is higher than the facet disorder of the cervical and lumbar vertebrae. Therefore, an ideal strategy to relieve thoracic facet joint disorder is urgently needed. In recent years, massage therapy has been increasingly accepted by thoracic facet joint disorder patients due to its lower costs, fewer unwanted side effects and safety for clinical use. In this systematic review, we aim to evaluate the effectiveness and safety of massage therapy for patients with thoracic facet joint disorder. METHODS: We will search the following electronic databases for randomized controlled trials to evaluate the effectiveness of massage therapy in treating thoracic facet joint disorder: Wanfang and PubMed Database, CNKI, CENTRAL, CINAHL and EMBASE. Each database will be searched from inception to October 2020. The entire process will include study selection, data extraction, risk of bias assessment and meta-analyses. RESULTS: This proposed study will evaluate the effectiveness of massage therapy for patients with thoracic facet joint disorder. CONCLUSIONS: This proposed systematic review will evaluate the existing evidence on the effectiveness and safety of massage therapy for patients with thoracic facet joint disorder. DISSEMINATION AND ETHICS: The results of this review will be disseminated through peer-reviewed publication. Because all of the data used in this systematic review and meta-analysis has been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process. OSF REGISTRATION NUMBER: DOI 10.17605/OSF.IO/XMEJD.

RESUMO

BACKGROUND AND AIM: Traditionally, surgery is the only choice for esophageal foreign bodies (FBs) penetrating into the mediastinum or cervical para-esophageal space. Recent progress in endoscopic techniques and devices has made it possible to perform endoscopic procedures in the mediastinum. Here, we describe a novel method to remove the entirely embedded esophagus-penetrating FBs through an endoscopic approach. METHODS: Patients who underwent endoscopic removal of entirely embedded esophagus-penetrating FBs were prospectively enrolled between December 2018 and June 2020. All procedures were performed by using five major steps: localization of the FB; mucosal incision; wound debridement, myotomy, and FB exposure; FB extraction; and closure of the esophageal wound. RESULTS: A total of five cases of entirely embedded esophagus-penetrating FBs were evaluated, two in children and three in adults. All FBs were successfully removed and extracted using a therapeutic endoscope and a hook knife or a hybrid knife and a grasping forceps as accessories. The average procedure time was 19.0 ± 12.4 min (range 10-40 min). The major surgical procedure was avoided in all patients. The average length of hospital stay was 3.8 ± 2.5 days (range 2-8 days). There were no severe short-term adverse events after all procedures. During the 1 month and 3 months follow-up, no patient developed long-term adverse events including stenosis of the esophagus and fistula formation. CONCLUSIONS: Endoscopic approach was a safe and effective way to remove entirely embedded esophagus-penetrating FBs.

RESUMO

Purpose: The number of families who lost their only child was over one million in 2012 in China, and it is growing rapidly every year. Without their only child, they will inevitably worry about their health and life for their later years. It is important to explore the quality of life and influencing factors of the parents. Methods: The cluster sampling method was adopted to select the participants in Wuhu city, Anhui province, central China. The generalized linear regression models were performed to analyze factors influencing EQ-VAS scores. Results: The parents with different monthly income (P = 0.001) and self-rated health status (P < 0.001) had different EQ-VAS scores. Educational level, self-rated health status, number of chronic diseases, depression and having grandchildren were significantly associated with their EQ-VAS score. Conclusion: The government should encourage public medical institutions to provide convenient health management and medical services to this vulnerable group. Priority treatment should be given to the parents who already have multiple diseases. The parents who were depressed should be given timely intervention. The government should give more financial subsidies to the parents who need to raise their grandchildren.

RESUMO

Due to the multi-potential differentiation and immunomodulatory function, mesenchymal stem cells (MSCs) have been widely used in the therapy of chronic and autoimmune diseases. Recently, the novel coronavirus disease 2019 (COVID-19) has grown to be a global public health emergency but no effective drug is available to date. Several studies investigated MSCs therapy for COVID-19 patients. However, it remains unclear whether MSCs could be the host cells of SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) and whether they might affect the SARS-CoV-2 entry into other cells. Here, we report that human MSCs barely express ACE2 and TMPRSS2, two receptors required for the virus endocytosis, indicating that MSCs are free from SARS-CoV-2 infection. Furthermore, we observed that MSCs were unable to induce the expression of ACE2 and TMPRSS2 in epithelial cells and macrophages. Importantly, under different inflammatory challenge conditions, implanted human MSCs failed to up-regulate the expression of ACE2 and TMPRSS2 in the lung tissues of mice. Intriguingly, we showed that a SARS-CoV-2 pseudovirus failed to infect MSCs and co-cultured MSCs did not increase the risk of SARS-CoV-2 pseudovirus infection in epithelial cells. All these results suggest that human MSCs have no risk of assisting SARS-CoV-2 infection and the use of MSCs as the therapy for COVID-19 patients is feasible and safe.

RESUMO

BACKGROUND: Postprandial distress syndrome (PDS), characterized by the presence of prevalently meal-related early satiation and fullness, is a highly prevalent condition with major socioeconomic and healthcare impact. To date, there is a lack of pharmacological treatment proven value for PDS. Therefore, an ideal strategy to relieve PDS is urgently needed. In recent years, massage therapy has been increasingly accepted by PDS patients due to its lower costs, fewer unwanted side effects and safety for clinical use. In this systematic review, we aim to evaluate the effectiveness and safety of massage therapy for patients with postprandial distress syndrome. METHODS: We will search the following electronic databases for randomized controlled trials to evaluate the effectiveness and safety of massage therapy in treating postprandial distress syndrome: Wanfang and Pubmed Database, CNKI, CENTRAL, CINAHL, and EMBASE. Each database will be searched from inception to October 2020. The entire process will include study selection, data extraction, risk of bias assessment, and meta-analyses. RESULTS: This proposed study will evaluate the effectiveness and safety of massage therapy for patients with postprandial distress syndrome. The outcomes will include changes in PDS relief and adverse effect. CONCLUSIONS: This proposed systematic review will evaluate the existing evidence on the effectiveness and safety of massage therapy for patients with postprandial distress syndrome. DISSEMINATION AND ETHICS: The results of this review will be disseminated through peer-reviewed publication. Because all of the data used in this systematic review and meta-analysis has been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process. OSF REGISTRATION NUMBER: DOI 10.17605/OSF.IO/9WRX8.

RESUMO

The combination of having a low physical performance and obesity results in a vicious cycle, but the effect of this combination on the incidence of hypertension is still unknown. This article aims to examine the effect of obesity and low physical performance on the incidence of hypertension in older adults. The sample was comprised of 349 Chinese community-dwelling participants (199 women; mean age 66.30 ± 5.78 years) without hypertension at baseline. Obesity was defined as having a body mass index (BMI) greater than or equal to 28 kg/m2. Participants scoring in the top 20% on the Timed Up and Go Test (TUGT) or in the slowest 20% of the 4-m walking test were defined as having a low physical performance. The outcome was new onset hypertension at the 1-year follow-up. We found that 89 (25.5%) of the 349 participants without hypertension at baseline had developed hypertension at their 1-year follow-up. After multivariate adjustments, it was found that the incidence of hypertension was associated with the combination of obesity and having a low physical performance (OR = 7.30, 95% CI = 1.36-39.11), but not solely with obesity (OR = 1.40, 95% CI = 0.68-2.88) or solely with low physical performance (OR = 0.98, 95% CI = 0.29-3.27). Hence, although obesity and low physical performance did not independently affect the incidence of hypertension after one year, the combination of the two can significantly increase the incidence of hypertension in Chinese community-dwelling older adults.

RESUMO

This study aimed to design and fabricate a customized distractor based on 3D printing technology and compare its mechanical properties with conventional distractor. The investigators designed and implemented a study composed of conventional and customized distractors. The design of customized distractor was based on the specification of conventional mandibular distractors and was fabricated using selective laser melting (SLM) technology. The same type of conventional distractors served as control group. Vickers-hardness test, three-point bending test and welding strength test were carried out for the conventional and customized distractor respectively and data was analyzed with t test using SPSS13.0 software package. The sample was composed of 18 distractors grouped as follows: customized distractor (n = 9) and conventional distractor (n = 9). The customized distractor showed better result than the conventional distractor in mechanical property tests, with statistically significant differences in Vickers-hardness and maximum load (P < 0.05), and no significant differences in yield strength and welding strength (P > 0.05). The results of this study suggest indicated that compared to the conventional distractor, the customized distractor had better mechanical properties and could be used in maxillofacial distraction osteogenesis.

RESUMO

PURPOSE: The purpose of this study was to compare the post-operative radiographic and clinical outcomes of less invasive plate fixation versus screw fixation of displaced intra-articular calcaneus fractures (DIACFs) via sinus tarsi approach. METHODS: A total of 165 consecutive DIACFs that underwent open reduction internal fixation via sinus tarsi approach from 2013 to 2018 were reviewed at least a two year follow-up. The methods of fixation were divided into two groups: less invasive plate fixation versus screw fixation of calcaneus fracture (59 vs 106, respectively). The radiographic outcomes including pre- and post-operative Bohler's and Gissane's angles were evaluated. The post-operative function was evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, the Olerud and Molander Scale and the Visual Analogue Scale (VAS). The complications, the rates of implant removal and cost were also compared. RESULTS: The average follow-up was 44.2 months in the plate groups and 47.9 months in the screw groups (P > 0.05). There was no significant difference in the Bohler's angle and Gissane's angle between the plate group and screw group during the pre-operation and the last follow-up. There was no significant difference in the final AOFAS score, Olerud and Molander score and VAS score between the two groups (P > 0.05). The total incidence of complications was 6.7% in the plate group and 6.6% in the screw group (P > 0.05). The rates of implant removal and total cost during the hospitalization in the plate group were significantly higher compared with screws group (P < 0.05). CONCLUSION: The less invasive plate fixation versus screw fixation of DIACFs via sinus tarsi approach contributed comparable quality of reduction, complications and post-operative functional outcomes. The less invasive plate technique was significantly higher in terms of implant costs and the rate of implant removal.

RESUMO

In this study, the degradation performance of nutrients in zeolite trickling filter (ZTF) with different influent C/N ratios and aeration conditions was investigated. Microaeration was beneficial for enhancing NH4+-N removal performance. Due to the sufficient carbon source supply under a C/N ratio of 8, a high removal efficiency of NH4+-N and TN was simultaneously observed in ZTF. In addition, TN removal mainly occurred at the bottom, which might be explained by the sufficient nutrients available for bacteria to multiply in this zone. The abundant genera were Acinetobacter, Gemmobacter, Flavobacterium, and Pseudomonas, all of which are heterotrophic nitrification-aerobic denitrification (HNAD) bacteria. In addition, biofilm only slowed down the adsorption rate but did not significantly reduce the adsorption capacity of zeolite. Bio-zeolite had NH4+-N well adsorption capacity and bio-desorption capacity. Biological nitrogen removal performance was superior to physicochemical absorption of zeolite. The results suggested that the physicochemical of zeolite and biochemical reactions of microorganism coupling actions may be the main nitrogen transformation pathway in ZTF. Our research provides a reference for further understanding the nitrogen removal mechanism of zeolite bioreactors.

RESUMO

PURPOSE: Circular RNAs (circRNAs) have been reported to act as important regulators in pancreatic cancer. Abnormal expression of circRNAs in pancreatic cancer cells (PCCs) can promote the development of pancreatic cancer; however, the role of circRNAs in cancer-associated pancreatic stellate cells (CaPSCs) remains unclear. PATIENTS AND METHODS: In this study, we isolated CaPSCs from pancreatic cancer tissues from 5 pancreatic cancer patients and NaPSCs from normal pancreatic tissue from 5 patients with benign pancreatic disease. After the PSCs were co-cultured with the pancreatic cancer cell line PANC-1, a CCK-8 assay was used to detect PANC-1 proliferation ability, and CaPSCs1, which had the strongest promoting effect on PANC-1 proliferation, and NaPSCs1, which had the weakest effect, were screened. Then, the circRNA, microRNA (miRNA) and mRNA profiles between CaPSCs1 and NaPSCs1 were compared by RNA-seq. The candidate circRNA/miRNA/target protein axis was selected using bioinformatics analysis. circRNAs were silenced and miRNAs were overexpressed in CaPSCs1, and the expression of circRNAs, miRNAs and target proteins were detected by qRT-PCR and Western blot, respectively. At the same time, CCK8, wound healing, and Transwell assays were used to detect the proliferation, migration and invasion of PANC-1 cells in the different co-culture groups. Moreover, a tumour xenograft model was used to observe the tumorigenic ability of PANC-1 cells in different co-culture groups. Finally, immunohistochemistry was used to detect the expression of target proteins in PDAC tissues, and the clinicopathological features and prognosis were analysed. RESULTS: The expression of the differentially expressed RNAs identified by RNA-seq was verified by qRT-PCR, and the chr7:154954255-154998784+/miR-4459/KIAA0513 axis was selected from the candidate targets. Functional studies of PANC-1 cells after co-culture with chr7:154954255-154998784+-silenced CaPSCs1 showed that the proliferation, invasion and metastasis of PANC-1 cells decreased. Moreover, after chr7:154954255-154998784+ was silenced, the expression of miR-4459 in CaPSCs1 increased, and the expression of KIAA0513 decreased. When PANC-1 cells were co-cultured with CaPSCs1 with miR-4459 overexpression, they showed an increased ability to proliferate, invade and metastasize. Additionally, when miR-4459 was overexpressed in CaPSCs1, the expression of chr7:154954255-154998784+ and KIAA0513 decreased. Animal experiments revealed that silencing chr7:154954255-154998784+ in CaPSCs1 inhibited tumour growth in nude mice inoculated with CaPSCs1+PANC-1 cells. Finally, we performed immunohistochemistry and a prognostic analysis of KIAA0513 expression in paraffin tissue samples from patients with pancreatic cancer and found that high expression of KIAA0513 was associated with more aggressive clinicopathological factors. Furthermore, patients with high expression of KIAA0513 had worse disease-free survival (DFS) and overall survival (OS). CONCLUSION: Chr7:154954255-154998784+ may promote the development of pancreatic cancer through the miR-4459/KIAA0513 axis in CaPSCs and may be an important therapeutic target for patients with pancreatic cancer in the future.

RESUMO

There is currently no available cure or universally effective treatment for dry eye (DE). The aim of the present study was to investigate the clinical efficacy of transcutaneous electrical stimulation (TES) combined with artificial tears in treating DE. Patients diagnosed with DE were referred for therapy with TES combined with sodium hyaluronate (SH)-containing artificial tears. A total of 52 patients (104 eyes) with DE were enrolled in this randomized controlled trial. The patients were randomized 1:1 to the TES + SH or SH group. The patients in the TES + SH group were treated with 20 sessions (5 sessions per week for 4 weeks), and each session lasted for 20 min. The treatment was continued for 4 weeks in all cases. The Ocular Surface Disease Index (OSDI), tear film breakup time (BUT), Schirmer's I test and corneal fluorescein scores were used to assess treatment efficacy. A total of 90 eyes of 45 patients completed all aspects of the study: 22 patients (44 eyes) in the TES + SH group and 23 patients (46 eyes) in the SH group. There was no statistically significant difference in sex, age or course between the two groups. The mean OSDI scores, BUT, Schirmer's I test and corneal fluorescein scores exhibited a significant improvement in the TES + SH group compared with the SH group after treatment. No serious adverse events were recorded during TES treatment. In conclusion, TES combined with artificial tears appeared to be an effective treatment for DE. Therefore, TES may represent a new therapeutic option with promising potential applications.

RESUMO

Larou is a traditional smoked meat product in China. In this experiment, larou was processed with different smoking materials and methods evaluating whether the control of processing methods could balance the quality of larou and the content of carcinogens. Pork bellies were marinated, dried and divided into four groups then directly smoked by four different smoking materials for 40 minutes. The best index smoking material would be brought into the indirect smoking device for larou single-factor variable indirect smoking with nano-activated carbon fiber. Results showed that the specific surface area of the nano-activated carbon fiber was 978.00 m 2 /g, and such fiber could effectively adsorb the smoking ash particles. In pomelo skins group (PS), the highest phenols content and variety were found as 4.48% and 11, which increased the smoking flavor most significantly. The moisture, SA, LAB, Y&M values were 32.64%, 0.98 log 10 CFU/g, 1.10 log 10 CFU/g, 0.59 log 10 CFU/g, which could best inhibit harmful bacteria and benefit microbial environment for larou fermentation maturity. The benzo[a]pyrene (B[a]P) content of indirect smoking device (IN) by PS was 1.82 µg/kg, whereas the B[a]P content of direct smoking by PS was 36.1 µg/kg, which indicated a significant difference ( p  < 0.01). These findings suggested that pomelo skins with indirect smoking device of larou could effectively maintain the inspection indexes and reduce the content of B[a]P. The control of this processing method can be used for the actual production of meat.

RESUMO

BACKGROUND: The efficacy and safety of secukinumab, an interleukin-17 inhibitor, as systemic treatment for patients with moderate-to-severe psoriasis have been demonstrated, but real-world data pertaining to this is limited in China. OBJECTIVE: To evaluate the efficacy and safety of secukinumab in clinical practice in Chinese psoriasis patients with or without psoriatic arthritis (PsA) and identify potential baseline factors that affect the response of patients to secukinumab treatment. MATERIALS & METHODS: Data from 81 patients treated with secukinumab for at least 16 weeks were analysed in a retrospective observational study. RESULTS: After 16 weeks of treatment with secukinumab, 91.1%, 73%, and 38.3% of patients achieved a PASI 75 (75% improvement based on the Psoriasis Area and Severity Index), PASI 90, and PASI 100, respectively. A significant improvement in the quality of life of patients was also observed. Notably, baseline factors, such as young age, lower BMI, no scalp involvement and absence of concomitant PsA, were associated with better clinical response to secukinumab. Approximately 42% of patients (34/81) experienced adverse events, of which the most common was pruritus. CONCLUSION: The results demonstrated that secukinumab appears to be an effective treatment alternative for the majority of Chinese plaque psoriasis patients. Baseline factors, including age, BMI, scalp involvement and concomitant presence of PsA, were associated with response to secukinumab.

RESUMO

Plant homeodomain finger protein 8 (PHF8) has been reported to participate in cancer development and metastasis of various types of tumors. However, little is known about the functional mechanism of PHF8 in gastric cancer (GC). This study aimed to explore the PHF8 expression pattern and function, and the role of the MYC/miRNA/PHF8 axis in GC. PHF8 expression was upregulated in GC tissues and cells as measured using quantitative reverse transcription polymerase chain reaction and western blotting. PHF8 knockdown suppressed the proliferation, migration, and invasion of GC cells, as determined using the CCK-8 assay and Transwell assay. MicroRNA-22-3p targeted PHF8, as verified by a dual-luciferase reporter assay. MYC upregulated the protein expression of PHF8 but had no effect on PHF8 mRNA expression. MYC regulates PHF8 by affecting the stability of miR-22-3p. We identified a novel MYC/miR-22-3p/PHF8 regulatory axis in GC. Therefore, PHF8 may provide a new therapeutic target for patients with GC.

OBJECTIVES: To compare the clinical outcomes of plate fixation and arthroscopic-assisted plate fixation in patients with displaced isolated medium-sized fractures of the greater tuberosity. METHODS: From July 2013 to October 2017, patients with displaced isolated medium-sized fractures of the greater tuberosity who underwent arthroscopic-assisted plate fixation (ASPF group) or open reduction and internal plate fixation (ORIF group) were retrospectively reviewed and analyzed. There were 19 patients in the ASPF group and 27 patients in the ORIF group, with comparable demographic characteristics. The average age of patients was 49.4 ± 12.1 years in the ASPF group and 46.9 ± 11.4 years in the ORIF group. The shoulder function reflected by the Constant-Murley (CS) scores, the American Shoulder and Elbow Surgeons (ASES) scores, and the range of motion (ROM) in the both groups at the last follow-up were analyzed in the study. Surgery time, postoperative pain, and postoperative complications were also reviewed. RESULTS: A total of 46 eligible patients were included in this study. The mean follow-up was similar for the ASPF (19.4 ± 3.7 months) and the ORIF (18.2 ± 3.2 months) groups (P = 0.372). All patients had achieved primary incision healing in both groups at the last follow-up. The surgery time was 96.8 ± 11.7 min and 64.2 ± 8.3 min in the ASPF group and the ORIF group, respectively (P < 0.01). All the CS scores (P = 0.278), ASES scores (P = 0.426), and ROM were slightly better in the ASPF group than in the ORIF group, but they did not attain significant differences. In addition, there was no significant difference in the postoperative complication rate between the ASPF group (10.5%) and the ORIF group (18.5%) (P = 0.522). In the ASPF group, there was only one patient with postoperative shoulder stiffness and one case of fracture malunion. In the ORIF group, there were two cases of postoperative shoulder stiffness, two cases of fracture malunoin, and one case of subacromial impingement. Other major postoperative complications, such as fracture nonunion, pullout of the suture anchor, and screw penetration, were not observed in either group. CONCLUSION: Arthroscopic-assisted plate fixation is effective and may be an alternative in the treatment of displaced isolated medium-sized fractures of the greater tuberosity.

RESUMO

Model warming projections, forced by increasing greenhouse gases, have a large inter-model spread in both their geographical warming patterns and global mean values. The inter-model warming pattern spread (WPS) limits our ability to foresee the severity of regional impacts on nature and society. This paper focuses on uncovering the feedbacks responsible for the WPS. Here, we identify two dominant WPS modes whose global mean values also explain 98.7% of the global warming spread (GWS). We show that the ice-albedo feedback spread explains uncertainties in polar regions while the water vapor feedback spread explains uncertainties elsewhere. Other processes, including the cloud feedback, contribute less to the WPS as their spreads tend to cancel each other out in a model-dependent manner. Our findings suggest that the WPS and GWS could be significantly reduced by narrowing the inter-model spreads of ice-albedo and water vapor feedbacks, and better understanding the spatial coupling between feedbacks.
