[PMID: 33966905 DOI: 10.1016/j.anplas.2021.03.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 03/24/2021] [Accepted: 03/29/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND Improving the survival rate of fat grafts is yet a difficult problem in the field of autologous fat transplantation. Prevailing methods such as making nanofat and SVF are time-consuming. Hence, the role of additives application in the improvement of fat graft survival during fat transplantation was considered and preliminarily evaluated in a rabbit animal model. METHODS A rabbit animal model was established where rabbit ears were injected with a mixture of 1.5mL of adipose tissue and 1mL of saline (group A), 1.5mL of adipose tissue and 1mL of botulinum toxin A (BoNTA) (group B), 1.5mL of adipose tissue and 1mL of prostaglandin E2 (groupC), 1.5mL of adipose tissue and 1mL of PDRN (group D) respectively. Then, the extents of neovascularization and inflammation were evaluated on the 7th, 14th, 28th, 42nd, 56th and 70th day after injection by ELISA assays and H&E and immunofluorescence staining. RESULTS The results showed that pre-treatment with BoNTA, prostaglandin E2 and PDRN improved graft volume and weight. The H&E and immunofluorescence staining revealed that BoNTA, prostaglandin E2 and PDRN improved the graft angiogenesis. Simultaneously, TNF-α expression level detected by ELISA was the lowest in the PDRN group. CONCLUSION Henceforth, the present preliminary study suggests that pre-transplantation treatment with BoNTA, prostaglandin E2 and PDRN can improve the fat graft angiogenesis and graft integrity, whereby the effect of adding PDRN may be significant.

Abstract
OBJECTIVE To uncover the role of LINC01287 in the progression of hepatocellular carcinoma (HCC) and the indicated molecular mechanism. PATIENTS AND METHODS Relative levels of LINC01287 and miR-559 in 32 pairs of HCC tissues and normal ones, as well as HCC cell lines were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Receiver operating characteristic (ROC) curves and Kaplan-Meier curves were depicted for assessing the diagnostic and prognostic potentials of LINC01287 in HCC, respectively. Proliferative and migratory capacities in HCC cells influenced by LINC01287 were assessed by cell counting kit-8 (CCK-8) and transwell assay, respectively. The regulatory loop LINC01287/miR-559/TCF12 was ascertained by Dual-Luciferase reporter assay. The involvement of the regulatory loop in the progression of HCC was examined via rescue experiments. RESULTS LINC01287 was upregulated in HCC tissues and cell lines, whereas miR-559 was downregulated. LINC01287 displayed certain diagnostic and prognostic potentials in HCC. Knockdown of LINC01287 could inhibit proliferative and migratory capacities in HCC cells. The regulatory loop LINC01287/miR-559/TCF12 was responsible for the aggravation of HCC. CONCLUSIONS LINC01287 drives proliferative and migratory capacities in HCC via targeting the miR-559/TCF12 axis.

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
BACKGROUND Cardiovascular disease (CVD) is the most common complication and the leading cause of death in patients with chronic kidney disease (CKD). Accelerated atherosclerosis is a pathophysiological process that is vital to the occurrence of cardiovascular complications associated with CKD. Abnormal platelet activation is not only the leading cause of atherosclerosis but also plays a critical role in the occurrence of thrombotic events. Currently, antiplatelet drugs are commonly used as a secondary prevention strategy for high blood pressure, obesity, diabetes, and ischemic heart disease and can reduce the risk of CVD in the susceptible population. However, the benefits and evidence of using antiplatelet agents in patients with CKD remain controversial. This study aimed to determine whether antiplatelet therapy can safely prevent atherosclerosis in patients with CKD in the primary care setting. METHODS/DESIGN The ALTAS-CKD study is a multicenter, prospective, randomized, double-blind, placebo-controlled trial of 554 adult patients with stage 3-5 non-dialysis-dependent CKD recruited from 10 territory medical centers in China. A secured web-based computer randomization system will be used to administer aspirin 100 mg once daily or a matching inactive placebo for 36 months. The primary endpoint will be the occurrence of atherosclerosis, as measured by carotid ultrasonography. The secondary endpoints will be combined cardiovascular events, all-cause mortality, and 50% decrease in the estimated glomerular filtration rate. TRIAL REGISTRATION {2A}: Current controlled trials number: ChiCTR1900021393 . Registered on 18 February 2019.

Abstract
PURPOSE Previous studies have indicated that platelet indices are related to the pathogenesis of cardiovascular diseases (CVD). However, it is unclear which platelet-related indicators are associated with CVD events in patients with chronic kidney disease (CKD) without dialysis. METHODS We performed a single-center prospective cohort study involved 1391 CKD patients to explore the relationship between platelet indices and CVD events in CKD patients. A nomogram was generated to predict CVD-free survival after 3 and 5 years of follow-up in terms of the fitted Cox regression model. And the time-dependent receiver-operating characteristic (ROC) curves were applied to evaluate the prediction accuracy of platelet indices on CVD events. RESULTS During a median follow-up of 3.41 years, 211 (15.2%) patients experienced CVD events. Results showed that platelet counts (PLT), plateletcrit (PCT), platelet-large cell ratio (P-LCR), and platelet distribution width (PDW) among 5 platelet indices were significantly lower in advanced CKD stages. Cox regression model showed that PLT, PDW, and PCT were associated with CVD events. However, after multivariable-adjusted, low level of PLT, hazard ratio (HR) 0.994 and 95% confidence interval (95% CI 0.989-1.000, p = 0.04), and PDW, HR 0.936 (95% CI 0.878-0.998, p = 0.044) predicted CVD events. The area under the ROC curve (AUC) of platelet indices assessed by time-dependent ROC curve analysis showed that only PLT and PDW were significant for predicting CVD events for 5 years. CONCLUSIONS We demonstrated that PLT and PDW among 5 platelet indices were independently associated with CVD events in patients with CKD.

Abstract
AIMS To investigate the potential role of renal arterial resistance index (RI) in the differential diagnosis between diabetic kidney disease (DKD) and non-diabetic kidney disease (NDKD) and establish a better-quantified differential diagnostic model. MATERIALS AND METHODS We consecutively reviewed 469 type 2 diabetes patients who underwent renal biopsy in our center. According to the renal biopsy results, eligible patients were classified into the DKD group and the NDKD group. The diagnostic significance of RI was evaluated by receiver operating characteristic (ROC) curve analysis. Logistic regression analysis was used to search for independent risk factors associated with DKD. Then a novel diagnostic model was established using multivariate logistic regression analysis. RESULTS A total of 332 DKD and 137 NDKD patients were enrolled for analysis. RI was significantly higher in the DKD group compared with those in the NDKD group (0.70 vs. 0.63, p< 0.001). The optimum cutoff value of RI for predicting DKD was 0.66 with sensitivity (69.2%) and specificity (80.9%). Diabetic retinopathy, diabetes duration ≥ 60 months, HbA1c ≥ 7.0(%), RI ≥ 0.66, and body mass index showed statistical significance in the multivariate logistic regression analysis. Then, we constructed a new diagnostic model based on these results. And the validation tests indicated that the new model had good sensitivity (81.5%) and specificity (78.6%). CONCLUSIONS RI has a potential role in discriminating DKD from NDKD. The RI-based predicting model can be helpful for differential diagnosis of DKD and NDKD.

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
Objectives The objective of this study was to evaluate whether the non-pharmaceutical interventions (NPIs) introduced to curb the spread of coronavirus disease 2019 (COVID-19) also interrupted the transmission of influenza. Study design This is a descriptive epidemiological study. Methods Data on changes in the number of reported influenza cases, number of influenza-like illness (ILI) visits, ILI percentage and influenza virus positivity were compared between the first 18 weeks of 2020 and the same period of 2019. Results The changes in the weekly average number of influenza cases were statistically significant between 2020 and 2019 (−4319 vs −525 per week; P < 0.05). The slopes of regression lines for the number of ILI visits were also statistically significant between 2020 and 2019 (−911 vs −98 per week; P < 0.05). Conclusions This study found that the prevalence of influenza was substantially decreased when NPIs were implemented for the containment of COVID-19. The prevalence of influenza was substantially decreased when non-pharmaceutical interventions were implemented for the containment of coronavirus disease 2019. Changes in the weekly average number of influenza cases were statistically significant between 2020 and 2019 (−4319 vs −525 per week; P < 0.05). Changes in the number of influenza-like illness visits were also statistically significant between 2020 and 2019 (−911 vs −98 per week; P < 0.05).

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.
