Abstract
OBJECTIVE Polypharmacy and multiple diseases are common in geriatric practice; however, such kind of multiple interventions might result in adverse effects. Some previous studies have found the association of polypharmacy and Parkinson's disease, to confirm this relationship, we conducted a meta-analysis to analyze this issue quantitively. MATERIALS AND METHODS In total, we included 8 studies, 165,689 polypharmacy subjects and 373,660 non-polypharmacy controls, and 5644 PD patients among these subjects and controls. RESULTS For model without any adjustment, polypharmacy group has a significantly higher prevalence than control, OR = 2.53, 95 %CI [2.00, 3.20] (p < 0.001). However, this model showed a very high heterogeneity (I2 = 91 %, p < 0.001). In age, gender and disease history adjusted model, polypharmacy group has a significantly higher prevalence than control, OR = 1.43, 95 %CI [1.35, 1.52], p < 0.001. The heterogeneity decreased to zero (I2 = 0 %, p < 0.45). CONCLUSION In this study we have found an association between PD risk and polypharmacy, a better designed prospective long-term cohort study might be required for further discussion on this issue (Tab. 1, Fig. 5, Ref. 14).

Abstract
Objective: To investigate the biological function of miR-758-3p and the underlying mechanism in non-small cell lung cancer (NSCLC). Methods: miR-758-3p mimics was transfected to A549 NSCLC cells, miRNA control was used as a negative control, cells transfected with nucleolar and spindle associated protein 1 (NUSAP1)-overexpression vector indicated as NUSAP1 group, cells co-transfected with miR-758-3p mimics and NUSAP1-overexpression vector indicated as miR-758-3p mimics+ NUSAP1 group. The effects of miR-758-3p on the proliferation, migration and invasion abilities of A549 cells were detected by cell counting kit-8 (CCK-8) and Transwell assays, respectively. Bioinformatics and dual luciferase reporter assay were used to predict and verify the target gene of miR-758-3p. Results: The expressions of miR-758-3p and NUSAP1 in A549 cells were significantly up-regulated at 24 hours after transfection with miR-758-3p mimics (P<0.05). Compared with the miRNA control group (1.15±0.06), the OD value of miR-758-3p mimic group (0.78±0.06) was significantly decreased at 72 hours after transfection (P<0.05). The number of migrated cells of miR-758-3p mimic group (119.04±11.49) was significantly lower than that of the control group (271.38±19.05) (P<0.05). The number of invaded cells of miR-758-3p mimic group (71.33±5.36) was significantly lower than the control group (164.30±8.11) (P<0.05). The result of dual-luciferase reporter assay showed that NUSAP1 was a direct target of miR-758-3p. Moreover, up-regulation of NUSAP1 abolished the inhibitory effects of miR-758-3p on the proliferation, migration and invasion abilities of A549 cells. Conclusion: miR-758-3p inhibits the proliferation, migration and invasion of NSCLC cells by targeting NUSAP1.

Abstract
This study aimed to evaluate the effectiveness and long-term outcomes of free and pedicled, expanded deltopectoral flaps with perforation of the internal thoracic artery to repair facial scars. This retrospective review was of 37 patients who presented between June 2013 and June 2019 with various types of facial scar. Ten patients received a free expanded deltopectoral flap and 27 a pedicled, expanded deltopectoral flap. During the stage-one operation, the expander was implanted into the deltopectoral area and fully expanded by normal saline injection. In stage two, the facial lesions were incised, and the free or pedicled flap transferred to reconstruct the defect. Flap necrosis did not occur in the 10 patients treated with free flaps. Two patients need to have the pedicle trimmed three months after surgery because it had become bloated. Distal necrosis occurred in five of 27 patients who received a pedicled, expanded deltopectoral flap. Healing by conservative treatment was noted in two cases and healing after skin grafting was documented in the other three. All 37 patients achieved satisfactory results. A pedicled, expanded deltopectoral flap appears to be a reliable and safe option for the treatment of facial scars.

Abstract
Secondary lower extremity lymphedema is a common complication of treatment for gynecological cancers. Conservative therapy plays an important role in the treatment of patients with secondary lower extremity lymphedema; in particular, complex decongestive therapy (CDT) has been recognized as an effective nonoperative technique for these patients. But CDT therapy for secondary lower extremity lymphedema remains a problem in China because this technique and its effectiveness have not achieved widespread use and popularity. Our goal was to assess effects of CDT in patients with secondary lower limb lymphedema after treatment for gynecological cancers. The retrospective study consisted of 60 patients who were treated with 20 sessions of CDT. Assessments included objective changes in limb circumference, degree of LE, imaging features, and incidence of erysipelas before and after CDT treatment. We found that CDT can effectively improve lymph stasis and promote backflow, and decrease circumference, interstitial fluid content, and incidence of erysipelas of lymphedematous lower limb. Our results demonstrate that CDT is an effective treatment method for patients with secondary lower limb lymphedema following treatment for gynecologic cancers. This technique should be more widely utilized and popularized in China to improve the quality of life of millions of patients with secondary lower limb lymphedema.

Abstract
Objective: To investigate the inhibitory effects of nucleolar and spindle associated protein 1 (NUSAP1) on lung cancer and the related mechanisms. Methods: A549 cells were transfected with NUSAP1 siRNA, the cell proliferation, migration and invasion, and apoptosis were detected by CCK8, Transwell and flow cytometry, respectively. Western blot was used to detect the expressions of apoptosis and AKT/mTOR signal pathway related proteins. Results: Compared with the negative control group, the proliferation [(0.610±0.058) vs (1.724±0.067), P<0.05], migration [(178.267±14.780) vs (272.464±36.232), P<0.05] and invasion [(73.527±6.617) vs (120.585±13.235), P<0.05] of NUSAP1 deleted A549 cells were significantly inhibited, while the apoptosis [(3.572±0.214)% vs (11.358±1.047)%, P<0.05] was significantly increased. The expressions of apoptosis related protein Bax and active-caspase 3 were increased (P<0.05), while the expressions of anti-apoptosis protein Bcl-2 and proliferation related protein P70, the phosphorylation levels of AKT and mTOR were reduced in NUSAP1 knockdown cells (P<0.05). Conclusion: NUSAP1 knockdown can inhibit the proliferation, migration and invasion, and promote the apoptosis of tumor cells through suppressing AKT/mTOR signaling pathway in lung cancer cells.

Abstract
BACKGROUND Although the interaction between gut microbiota and pouchitis after ileal pouch anal anastomosis (IPAA) for ulcerative colitis (UC) has been confirmed, evidence of commensal mycobiota in the etiology of pouchitis is still lacking. This study aimed to investigate the role of fungi in the pathogenesis of pouchitis. METHODS Fecal samples were collected from UC patients with or without pouchitis after IPAA. Experimental pouchitis was induced by 5% dextran sulfate sodium for 7 consecutive days in a rat model of IPAA. Fungal dysbiosis was induced by 0.5% fluconazole (Flu), and commensal fungal recognition through dectin-1 was blocked by 5% laminarin. Fecal fungal composition was analyzed using internal transcribed spacer 2 sequencing. Severity of pouchitis and activation of the CARD9-nuclear factor kappa-B pathway was determined among different groups. RESULTS Patients with pouchitis had a lower alpha (α) diversity in mycobiota composition and a higher abundance of Saccharomyces at the genus level compared with those with a normal pouch. In the rat model of pouchitis, Flu treatment decreased fungal burden but induced fungal dysbiosis, characterized by increased α diversity, a decreased relative abundance of Kazachstania, and increased Polythrincium and Saccharomyces. In addition, Flu treatment worsened dextran sulfate sodium pouchitis, as indicated by increased mortality, weight loss, higher histological score, and CD4+ cell infiltration. Laminarin also increased the severity of pouchitis. In the Flu and laminarin groups, the expression of interferon-γ, tumor necrosis factor-α, CARD9, and phosphorylated nuclear factor kappa-B inhibitor alpha was decreased. CONCLUSIONS Patients with pouchitis had altered fungal composition. Fungal dysbiosis or recognition deficiency by the host may exacerbate experimental pouchitis. Strategies targeting commensal mycobiota may provide therapeutic potential against pouchitis, especially for antibiotic-refractory patients.

Abstract
Abstract
Background
Numerous genome-wide association studies revealed that SNPs at phosphatase and actin regulator 1 (PHACTR1) locus are strongly correlated with coronary artery disease (CAD). However, the mechanism linking these variants to CAD remains uncertain.
Purpose
We studied the biological functions and molecular mechanisms of PHACTR1 in atherosclerosis.
Methods and results
Analysis of GTEx database showed that CAD-related SNPs in PHACTR1 are cis-eQTLs for PHACTR1 in arteries. Therefore, we generated Phactr1 knockout mice and crossed them with apolipoprotein E-deficient (ApoE−/−) mice to induce atherosclerosis by high-fat/high-cholesterol (HF-HC) diet. Phactr1 deficiency significantly inhibited atherosclerosis with decreased inflammatory cell infiltration. Western blot showed that PHACTR1 was restricted to endothelial cells (ECs) in mice. Mechanistically, RNAseq of aortic ECs revealed that the major molecular function of PHACTR1 was transcriptional regulation. PPARγ/RXRα was the top transcription factor, and PPARγ target gene expression substantially increased in Phactr1−/− mice. Moreover, we generated endothelial cell specific Phactr1−/−, ApoE−/− mice and found decreased atherosclerotic plaque area in aortic sinus. In vitro, PHACTR1 associated with PPARγ and inhibited PPARγ transcriptional activity. The inhibitory effect of PHACTR1 on PPARγ required its shuttling from cytosol to nucleus triggered by disturbed flow, a well-established pro-atherosclerotic stimulus.
Conclusion
Our results identified PHACTR1 as a mechanosensitive corepressor of PPARγ in ECs to promote atherosclerosis. Endothelial PHACTR1 is a potential therapeutic target for atherosclerosis treatment.

Abstract
BACKGROUND Polymeric micellar paclitaxel (pm-Pac) is a novel Cremophor EL-free, nanoparticle micellar formulation of paclitaxel. We aimed to compare the efficacy and safety between pm-Pac plus cisplatin and solvent-based paclitaxel (sb-Pac) plus cisplatin in advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS A total of 448 stage IIIB to IV NSCLC patients were randomly assigned (2:1) to receive six 3-week cycles of either pm-Pac (230 mg/m2) plus cisplatin (70 mg/m2; n = 300), followed by dose escalation of pm-Pac to 300 mg/m2 from the second 3-week cycle if prespecified toxic effects were not observed after the first cycle, or sb-Pac (175 mg/m2) plus cisplatin (70 mg/m2; n = 148). The primary end point was objective response rate (ORR) assessed by independent review committees (IRCs). The secondary end points included IRC-assessed progression-free survival (PFS), overall survival (OS), and safety. RESULTS Patients in the pm-Pac-plus-cisplatin group showed significant improvements in IRC-assessed ORR compared with those in the sb-Pac-plus-cisplatin group (50% versus 26%; rate ratio 1.91; P < 0.0001). Additionally, subgroup analysis showed that a higher ORR was consistently observed in both squamous and nonsquamous histological types. IRC-assessed median PFS was significantly higher in the pm-Pac-plus-cisplatin group than in the sb-Pac-plus-cisplatin group (6.4-month versus 5.3-month; hazard ratio 0.63; P = 0.0001). Median OS was not significantly different between the two groups. The incidence of treatment-related serious adverse events (9% versus 18%; P = 0.0090) was significantly lower in the pm-Pac-plus-cisplatin group than in the sb-Pac-plus-cisplatin group. CONCLUSION Pm-Pac plus cisplatin yielded superior ORR and PFS along with a favorable safety profile and should become an option for patients with advanced NSCLC.

Abstract
OBJECTIVE Esophagus squamous cell carcinoma (ESCC) was a dominant histological type of esophagus cancer, which has a very high incidence due to distant metastasis and local invasion. MicroRNA-148a (miR-148a) functioned as a tumor suppressor in a variety of cancers. The purpose of our study was to explore the vital role of miR-148a in esophagus squamous cell carcinoma. PATIENTS AND METHODS The Kaplan-Meier method was applied to calculate the 5-year overall survival of esophagus squamous cell carcinoma patients. Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) and Western blot were conducted to calculate the mRNA levels of miR-148a and genes. The cell counting kit-8 (CCK-8) and transwell assays were performed to measure the proliferative and invasive ability. RESULTS MiR-148a was observed to be significantly downregulated and the downregulation of miR-148 predicted poor prognosis of esophagus squamous cell carcinoma patients. MAP3K9 was a target gene of miR-148a and its expression was mediated by miR-148a through directly binding to the 3'-untranslated region (3'-UTR) of its mRNA in the esophagus squamous cell carcinoma. Moreover, miR-148a remarkably inhibited the proliferation and invasion through directly targeting to MAP3K9 via extracellular-signal-regulated kinase (ERK)/mitogen-activated protein kinase (MAPK) pathway and epithelial-mesenchymal transition (EMT) in the ESCC cells. In addition, overexpression of miR-148a inhibited the growth of ESCC in vivo. CONCLUSIONS MiR-148a inhibited the proliferation and invasion through directly targeting to MAP3K9 by ERK/MAPK pathway and EMT in ESCC cells. The newly identified miR-148a/MAP3K9 axis provides a novel insight into the pathogenesis of the esophagus squamous cell carcinoma.

Abstract
Objective: To evaluate clinical effect of deproteinized bovine bone for delayed implantation after fenestration. Methods: This trial is a continuation of a prospective clinical trial. From May 2011 to February 2015 in Department of Implantology, School of Stomatology, The Fourth Military Medical University after planting division of 55 cases of maxillary teeth missing area of residual alveolar bone height ≤5 mm patients. There were 21 female and 34 male patients, their average age were (55.2±7.1) years. A total of 62 side fenestration of maxillary sinus floor lift, clinical and imaging examination, evaluation of implant retention rate, complications, peripheral soft tissue health and marginal bone resorption. Results: A total of 82 implants were followed up in 41 patients. The average follow-up time was (51.8±14.3) months (36-78 months). The follow-up rate of the maxillary sinus was 75.8% (47/62), the follow-up rate of the implant was 73.9% (82/111), and the implant survival rate was 98.8% (81/82). The bone resorption results at the implant margins were (0.64±0.63) mm (-0.28 mm, 1.47 mm) in the near and (0.49±0.73) mm (-0.51 mm, 1.21 mm) in the far, the improved hemorrhage index was 0.46±0.72, the improved plaque index was 0.60±0.87, and the keratinized mucosa width was (2.14±1.22) mm. The incidence rate of peri-implant mucositis was 28.4% (23/81) among 23 implants, and there was no complication of peri-implant inflammation. Conclusions: This study shows that under the condition of insufficient sinus ridge spacing in the maxillary posterior area, it is feasible to use bovine bone alone to remove protein for delayed implantation of maxillary sinus floor elevation by windowing, and the clinical effect is reliable.

Abstract
Staphylococcus aureus is a major human pathogen that has acquired alarming broad-spectrum antibiotic resistance. One group of secreted toxins with key roles during infection is the phenol-soluble modulins (PSMs). PSMs are amphipathic, membrane-destructive cytolytic peptides that are exported to the host-cell environment by a designated adenosine 5'-triphosphate (ATP)-binding cassette (ABC) transporter, the PSM transporter (PmtABCD). Here, we demonstrate that the minimal Pmt unit necessary for PSM export is PmtCD and provide its first atomic characterization by single-particle cryo-EM and x-ray crystallography. We have captured the transporter in the ATP-bound state at near atomic resolution, revealing a type II ABC exporter fold, with an additional cytosolic domain. Comparison to a lower-resolution nucleotide-free map displaying an "open" conformation and putative hydrophobic inner chamber of a size able to accommodate the binding of two PSM peptides provides mechanistic insight and sets the foundation for therapeutic design.

Abstract
Aims Preoperative diagnosis is important for revision surgery after prosthetic joint infection (PJI). The purpose of our study was to determine whether reverse transcription-quantitative polymerase chain reaction (RT-qPCR), which is used to detect bacterial ribosomal RNA (rRNA) preoperatively, can reveal PJI in low volumes of aspirated fluid. Methods We acquired joint fluid samples (JFSs) by preoperative aspiration from patients who were suspected of having a PJI and failed arthroplasty; patients with preoperative JFS volumes less than 5 ml were enrolled. RNA-based polymerase chain reaction (PCR) and bacterial culture were performed, and diagnostic efficiency was compared between the two methods.According to established Musculoskeletal Infection Society (MSIS) criteria, 21 of the 33 included patients were diagnosed with PJI. Results RNA-based PCR exhibited 57.1% sensitivity, 91.7% specificity, 69.7% accuracy, 92.3% positive predictive value, and 55.0% negative predictive value. The corresponding values for culture were 28.6%, 83.3%, 48.5%, 75.0%, and 40.0%, respectively. A significantly higher sensitivity was thus obtained with the PCR method versus the culture method. Conclusion In situations in which only a small JFS volume can be acquired, RNA-based PCR analysis increases the utility of preoperative puncture for patients who require revision surgery due to suspected PJI.

Abstract
Background:Takayasu arteritis (TA) is the most prevalent large-vessel vasculitis in children. Patients with TA have a high mobidity and mortality.It remains a therapeutic challenge because corticosteroids monotherapy can rarely cure TAK and the relapse rate is high during GC tapering.Objectives:The aim of this study is to investigate the efficacy and safety of tocilizumab (TCZ)in Chinese children with Takayasu arteritis(TAK).Methods:We retrospectively studied 6 TAK children treated with TCZ in our hospital from July 2017 to October 2018. The demographic and clinical data, laboratory examination results and vascular imaging data were collected.Results:Six pediatric patients with critical or refractory TAK treated with TCZ were analyzed, including 3 males and 3 females.The diagnosis age was ranging in age from 2 to 13 years(median age:7 years).Three patients were initially treated with TCZ and Mycophenolate Mofetil(MMF) as the first-line regimen without corticosteroid or with a quite rapid GC taper duration,two of which had lifte-threatening coronary arteries involved and heart failure.The other three paitients were swcithed to TCZ from conventional disease modifying anti-rheumatic drugs (DMARDs) or other biologics due to being refractory to them and recurrent relapses.Four patients were given TCZ at 4 weeks regular intervals for 10 to 22 months,while two patients withdrew TCZ because of disease deterioration and unbearable abdominal or chest pain after the second dose.After 6 months follow-up,four patients experienced significant clinical and biological improvement with angiographically progression in one patient. A corticosteroid-sparing effect is obvious. Drug-related side effects occur in 1 patients manifesting as a mild elevated liver fuction. Neither neutropenia nor infection was observed.Conclusion:Our study shows a clinical, biological, and radiological response in patients with refractory TAK treated with TCZ.References :[1]Hellmich B, Agueda A, Monti S,et al.2018 Update of the EULAR recommendations for the management of large vessel vasculitis.

Abstract
Background:Osteoporosis and renal insufficiency are coexisting disease states in a substantial proportion of postmenopausal women. Since bisphosphonates are generally contraindicated in patients with estimated glomerular filtration rate (eGFR) <35 mL/min, it is important to evaluate other osteoporosis treatments in this setting.Objectives:To determine if baseline renal function affects the efficacy and safety of romosozumab.Methods:We performed post hoc analyses of two clinical trials of romosozumab in postmenopausal women with osteoporosis. In ARCH (NCT01631214), 4,093 patients were randomised 1:1 to romosozumab 210 mg monthly or alendronate 70 mg weekly for 12 months (mean age: 74.3 years; 96.1% with prevalent vertebral fractures [VFx]). In FRAME (NCT01575834), 7,180 patients were randomised 1:1 to romosozumab 210 mg or placebo monthly for 12 months (mean age: 70.9 years; 18.3% with prevalent VFx). For these analyses, patients were categorised by baseline eGFR (mL/min/1.73m2): normal renal function (eGFR ≥90), mild renal insufficiency (eGFR 60–89), or moderate renal insufficiency (eGFR 30–59). Least squares mean (LSM) percent change from baseline in bone mineral density (BMD) at the lumbar spine, total hip, and femoral neck; incidence of new VFx and adverse events (AEs); and changes in renal function were assessed for each eGFR category at Month 12 of the double-blind treatment period.Results:At baseline, most patients had mild/moderate renal insufficiency: 84% in ARCH, 88% in FRAME. In both studies, change from baseline in BMD was significantly higher in the romosozumab group across baseline eGFR categories (Figure). There was an interaction between BMD increase and renal function, and although BMD increase was not as large in women with impaired renal function, differences between romosozumab and control groups remained significant (Figure). In ARCH, among patients with eGFR ≥90, 60–89, and 30–59, the incidence of new VFx (romosozumab vs alendronate) at Month 12 was 3.3% vs 7.3%, 3.2% vs 3.9%, and 3.4% vs 6.2% in ARCH. In FRAME, the incidence of new VFx (romosozumab vs placebo) at Month 12 was 0.5% vs 3.0%, 0.4% vs 1.5%, and 0.6% vs 2.1%.In both studies, the incidences of AEs and serious AEs were similar in both treatment groups within and across eGFR categories. AEs of mild-to-moderate hypocalcaemia (investigator reported) occurred in two patients in ARCH (one romosozumab [eGFR 60–89] and one alendronate [eGFR ≥90]), and one patient in FRAME (romosozumab [eGFR 60–89]). Five patients in ARCH (all in the alendronate group) and 19 patients in FRAME (14 romosozumab, 5 placebo) had decreases in serum Ca levels (albumin adjusted); in the romosozumab group all were mild (<LLN–8.0 mg/dL) or moderate (<8.0–7.0 mg/dL). A similar percentage of patients in each group had changes in renal function over 12 months of treatment.Conclusion:The efficacy and safety of romosozumab vs alendronate or placebo was similar among postmenopausal women with osteoporosis and different levels of renal function.Acknowledgments:This study was funded by Amgen, Astellas and UCB Pharma.

Abstract
Background:SpA has historically been a difficult clinical diagnosis, especially early diagnosis. Two imaging techniques that address this problem are magnetic resonance imaging (MRI) and Single-Photon Emission Computed Tomography-Computed Tomography (SPECT-CT). Their accuracies have not been adequately compared.Objectives:The purpose of this study is to compare the sensitivities and specificities of SPECT-CT and MRI in SpA.Methods:This retrospective study assessed all patients who underwent SPECT-CT of the sacroiliac joint to assess for SpA. The results of SPECT-CT were compared against MRI for all patients in the cohort who underwent an MRI within 4 weeks of the SPECT-CT. A diagnosis of SpA in the discharge summary was considered the reference standard, and was based on a combination of clinical scenario, response to therapy, imaging,, patient history or lab index.Results:200 patients (173 men; average 22±4 years of age) were included SpA was diagnosed in 189 (AS patients=99 and excluded in 11. SPECT-CT and MRI had similar (P >0 .05;k ¼ 0.74) sensitivities (0.94 vs 0.94),specificities (1.00 vs 1.00),positive predictive values (1.00 vs 1.00),negative predictive values (0.94 vs 0.80),and accuracies (0.97 vs 0.95) when compared to the reference standard.Conclusion:Although MRI remains the initial modality of choice in early diagnosing SpA, SPECT-CT appears diagnostically equivalent and should be considered a viable supplementary or alternative imaging modality particularly if there is contra-indication or inaccessibility to MRI.References:[1]Taurog J D, Chhabra A, Colbert R A.
