Prognosis of Connective Tissue Disease Related Interstitial Lung Disease after Initiation of Long-Term Oxygen Therapy: Comparison with Idiopathic Pulmonary Fibrosis

Objective: The studies of long-term oxygen therapy (LTOT) for patents with connective tissue disease-related interstitial lung disease (CTD-ILD) are limited. This study aimed to evaluate the prognosis of CTD-ILD patients following the initiation of LTOT, compared to those with idiopathic pulmonary fibrosis (IPF). Methods: We conducted a retrospective analysis of patients with CTD-ILD and IPF who were introduced to LTOT between January 2014 and December 2020. Results: The study included 24 patients with CTD-ILD and 55 patients with IPF. At the initiation of LTOT, female gender, never-smoking history, higher body mass index (BMI), higher lactate dehydrogenase (LDH) level, lower pulmonary Surfactant Protein-D (SP-D) level and lower Gender-Age-Physiology (GAP) scores were more common in the CTD-ILD group (all Conclusion: Although patients with CTD-ILD had longer overall survival than those with IPF, there was no significant difference in prognosis after the initiation of LTOT between the two groups. Early intervention including treatment and management will be needed in CTD-ILD as in IPF.

Oncological results, functional outcomes and health-related quality-of-life in men who received a radical prostatectomy or external beam radiation therapy for localized prostate cancer： a study on long-term patient outcome with risk stratification

Health-related quality-of-life （HRQOL） after a radical prostatectomy （RP） or extemal beam radiation therapy （EBRT） has not been studied in conjunction with oncological outcomes in relation to disease risk stratification. Moreover, the long-term outcomes of these treatment approaches have not been studied. We retrospectively analyzed oncological outcomes between consecutive patients receiving RP （n = 86） and EBRT （n = 76） for localized prostate cancer. HRQOL and functional outcomes could be assessed in 62 RP （79%） and 54 EBRT （79%） patients over a 3-year follow-up period （median： 41 months） using the Medical Outcomes Study Short Form-36 （SF-36） and the University of Califomia Los Angeles Prostate Cancer Index （UCLA PCI）. The 5-year biochemical progression-free survival did not differ between the RP and EBRT groups for low-risk （74.6% vs. 75.0%, P = 0.931） and intermediate-risk （61.3% vs. 71.1%, P = 0.691） patients. For high-risk patients, progression-free survival was lower in the RP group （45.1%） than in the EBRT group （79.7%） （P = 0.002）. The general HRQOL was comparable between the two groups. Regarding functional outcomes, the RP group reported lower scores on urinary function and less urinary bother and sexual bother than the EBRT group （P 〈 0.001, P 〈 0.05 and P 〈 0.001, respectively）. With risk stratification, the low- and intermediate-risk patients in the RP group reported poorer urinary function than patients in the EBRT group （P 〈 0.001 for each）. The sexual function of the high-risk patients in the EBRT group was better than that of the same risk RP patients （P 〈 0.001）. Biochemical recurrence was not associated with the UCLA PCI score in either group. In conclusion, low- to intermediate-risk patients treated with an RP may report relatively decreased urinary function during long-term follow-up. The patient＇s HRQOL after treatment did not depend on biochemical recurrence.

A study on sleep architecture in patients with chronic respiratory failure under long-term oxygen therapy—Focused on the influence of ventilatory failure (high CO₂) elements on the patient’s sleep architecture

Sleep disturbance related symptoms are common in patients with long-term oxygen therapy (LTOT). Essentially, there were only few previous reports about the sleep architecture in patients with respiratory disease, such as chronic obstructive pulmonary disease (COPD). This study aims to clarify the objective sleep state and the elements that affect sleep architecture in Chronic Respiratory Failure (CRF) patients with focus on clinical cases of chronic hypercapnia. 13 subjects with chronic respiratory failure were enrolled in the study. All the subjects were pre-evaluated by pulmonary function test and Arterial blood gas analysis (ABG) including exercise testing. Polysomnography (PSG) test was performed in each subject with supplemental oxygen. The estimated base line PaCO2 value that reflects overall PaCO2 including sleep period was calculated using equation of PaCO2[2.4×(HCOˉ3)-22]from obtained ABG value just before PSG test. 6 subjects were classified as hypercapnic group (base line PaCO2 ≥ 45 mmHg) and 7 subjects were non-hypercapnic group (base line PaCO2 < 45 mmHg). Latency persistent sleep of PSG data was significant higher in patients with hypercapnic than non-hypercapnic (p < 0.01). Periodic Limb Movement was seen in 23.6% of the subjects, however there was no contribution for arousals. Other PSG data include mean SpO2 were no significant difference. This study suggests that patients with estimated hypercapnia had more disturbed sleep architecture especially significant loss of sleep latency than non-hypercapnic patient with chronic respiratory failure under LTOT. Nocturnal PaCO2 level or ventilatory function may contribute to sleep disturbance in patients with estimated hypercapnia during LTOT.

Short-course or long-course radiation therapy as a part of a neoadjuvant regimen for stage Ⅱ & Ⅲ rectal adenocarcinoma?

The aim of this mini-review is to compare and contrast the pros and cons of short-course and long-course neoadjuvant chemoradiation therapy regimens for stageⅡ&Ⅲrectal adenocarcinoma.Multiple trials have demonstrated the equal efficacy and safety of short-course and long-course radiation therapy as a part of neoadjuvant regimens.Published data also shows that total neoadjuvant therapy could be more successful than neoadjuvant chemoradiation followed by adjuvant chemotherapy.This review points out future research directions for patients with locally advanced rectal adenocarcinoma such as comparing total neoadjuvant therapy that contains a short-course of radiation therapy to the standard of care,and evaluating how the sequence of short-course radiation therapy and chemotherapy in the total neoadjuvant therapy impacts the pathological complete response(pCR)rate,local control,and survival outcomes.

Long non-coding RNAs with essential roles in neurodegenerative disorders

Recently,with the advent of high-resolution and high-throughput sequencing technologies,an increasing number of long non-coding RNAs(lncRNAs)have been found to be involved in the regulation of neuronal function in the central nervous system with specific spatiotemporal patterns,across different neurodegenerative diseases.However,the underlying mechanisms of lncRNAs during neurodegeneration remain poorly understood.This review provides an overview of the current knowledge of the biology of lncRNAs and focuses on introducing the latest identified roles,regulatory mechanisms,and research status of lncRNAs in Alzheimer's disease,Parkinson's disease,Huntington's disease,and amyotrophic lateral sclerosis.Finally,this review discusses the potential values of lncRNAs as diagnostic biomarkers and therapeutic targets for neurodegenerative diseases,hoping to provide broader implications for developing effective treatments.

Long noncoding RNA steroid receptor RNA activator 1 inhibits proliferation and glycolysis of esophageal squamous cell carcinoma

BACKGROUND The clinical effects and detailed roles of long non-coding RNA(LncRNA)steroid receptor RNA activator 1(SRA1)in esophageal squamous cell carcinoma(ESCC)remain ambiguous.In the present study,the complementary sites between lncRNA SRA1,miRNA-363-5p,and phospholysine phosphohistidine inorganic pyrophosphate phosphatase(LHPP)predicted via bioinformatics analysis stimulated us to hypothesize that miRNA-363-5p/LHPP axis might be required for SRA1-mediated ESCC progression.AIM To investigate the molecular events of SRA1 in the malignant behavior in ESCC.METHODS Thirty-eight ESCC tissues and paired adjacent normal tissues were acquired.SRA1 expression was detected in ESCC tissues and cell lines using quantitative reverse transcription-polymerase chain reaction.Cell counting Kit-8 assay,transwell invasion assay,glycolysis assay,and xenograft tumor model were performed to address the malignant biological behaviors of ESCC cells after the introduction of SRA1.The t-test and theχ2 test were used for comparison between groups.Survival curve analysis was performed using the Kaplan-Meier method.RESULTS SRA1 downregulation was identified in ESCC.ESCC patients exhibiting a low SRA1 expression faced shorter overall survival than those with a high SRA1 expression.The introduction of SRA1 inhibited cell proliferation,glucose uptake,and lactate production in ESCC.In vivo,the growth of ESCC was hindered by SRA1 overexpression.Then,SRA1 overexpresses the LHPP by inhibiting miRNA-363-5p.Lastly,the introduction of small interfering RNA si-LHPP or miRNA-363-5p mimic could abrogate the inhibition roles triggered by SRA1.CONCLUSION SRA1 inhibits the oncogenicity of ESCC via miRNA-363-5p/LHPP axis.The SRA1/miRNA-363-5p/LHPP pathway may be a therapeutic target for ESCC.

Expression profiles of long noncoding RNAs in retinopathy of prematurity

Long noncoding RNA(lncRNA)regulates the proliferation and migration of human retinal endothelial cells,as well as retinal neovascularization in diabetic retinopathy.Based on similarities between the pathogenesis of retinopathy of prematurity(ROP)and diabetic retinopathy,lncRNA may also play a role in ROP.Seven-day-old mice were administered 75±2% oxygen for 5 days and normoxic air for another 5 days to establish a ROP model.Expression of lncRNA and mRNA in the retinal tissue of mice was detected by high-throughput sequencing technology,and biological functions of the resulted differentially expressed RNAs were evaluated by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses.The results showed that compared with the control group,57 lncRNAs were differentially expressed,including 43 upregulated and 14 downregulated,in the retinal tissue of ROP mice.Compared with control mice,42 mRNAs were differentially expressed in the retinal tissue of ROP mice,including 24 upregulated and 18 downregulated mRNAs.Differentially expressed genes were involved in ocular development and related metabolic pathways.The differentially expressed lncRNAs may regulate ROP in mice via microRNAs and multiple signaling pathways.Our results revealed that these differentially expressed lncRNAs may be therapeutic targets for ROP treatment.This study was approved by the Medical Ethics Committee of Shengjing Hospital of China Medical University on February 25,2016(approval No.2016PS074K).

Yu Gan Long Ameliorates Hepatic Fibrosis by Inhibiting PI3K/AKT,Ras/ERK and JAK1/STAT3 Signaling Pathways in CCl4-induced Liver Fibrosis Rats

Yu Gan Long(YGL)is a Chinese traditional herbal formula which has been reported to attenuate liver fibrosis for many years and we have explored its anti-fibrotic mechanism through blocking transforming growth factor(TGF-β)in the previous study.But the mechanisms associated with platelet-derived growth factor(PDGF)-BB remain obscure.In this study,we further investigated the mechanism of YGL reducing carbon tetrachloride(CCl4)-induced liver fibrosis in rats.Our results showed that YGL suppressed CCl4-induced upregulation of collagen IV(Col IV),type HI precollagen(PCHI),hyaluronuc acid(HA)and laminin(LN),which are implicated in liver fibrosis.Also,YGL reduced theα-smooth muscle actin(α-SMA)expression,which acts as the indicator of liver fibrosis.Furthermore,YGL decreased the serum levels of hepatic stellate cell(HSC)mitogen PDGF-BB and inflammation cytokines,including TNF-α,IL-1β,IL-6.Markers involved in liver fibrosis,such as Ras,p-Raf-1,p-ERK1/2,p-JNK,p-P38,p-PI3K,p-AKT,p-JAKl,p-STAT3 were downregulated significantly after treatment with YGL.Our results indicated that YGL ameliorated CCl4-induced liver fibrosis by reducing inflammation cytokines production,and suppressing Ras/ERK,PI3K/AKT,and JAK1/STAT3 signaling pathways,which provided further evidence towards elucidation of the anti-fibrotic mechanism of YGL.

Main factors influencing long-term outcomes of liver transplantation in 2022

Liver transplant(LT)outcomes have markedly improved in the recent decades,even if long-term morbidity and mortality are still considerable.Most of late deaths are independent from graft function and different comorbidities,including complications of metabolic syndrome and de novo neoplasms,seem to play a key role in determining long-term outcomes in LT recipients.This review discusses the main factors associated with late mortality and suggests possible strategies to improve long-term management and follow-up after liver transplantation.In particular,the reduction of drug toxicity,the use of tools to identify high-risk patients,and setting up a multidisciplinary team also for long-term management of LT recipients may further improve survival after liver transplantation.

Hyperbaric Oxygen Treatment for Long COVID:From Molecular Mechanism to Clinical Practice

Long COVID symptoms typically occur within 3 months of an initial COVID-19 infection,last for more than 2 months,and cannot be explained by other diagnoses.The most common symptoms include fatigue,dyspnea,coughing,and cognitive impairment.The mechanisms of long COVID are not fully understood,but several hypotheses have been put forth.These include coagulation and fibrosis pathway activation,inflammatory and autoimmune manifestations,persistent virus presence,and Epstein-Barr virus reactivation.Hyperbaric oxygen therapy(HBOT)is a therapeutic method in which a person inhales 100%oxygen under pressure greater than that of the atmosphere.HBOT has some therapeutic effects,including improvement of microcirculation,inhibition of cytokine release leading to a reduction in inflammatory responses,inhibition of autoimmune responses,and promotion of neurological repair.Several clinical trials have been carried out using HBOT to treat long COVID.The results suggest that HBOT helps to improve symptom severity,reduce symptom duration,and enhance patients’quality of life.It is believed that HBOT is an effective option for patients with long COVID,which is worth actively promoting.

Long-term follow-up of two interventional procedures for achalasia

Objective To observed the long-term follow-up of the two types of interventional procedure for achalasia. Methods The study cohort was comprised of 140 patients of achalasia including 70 patients treated under fluoroscopy with pneumatic dilation (group A) and 70 with temporary partially covered metal stent dilation (group B). Results One hundred and forty dilations were performed on the 70 patients of group A with complications of chest pain (n=35), reflux (n=18), and bleeding (n=8); 38 patients of relapsing dysphagia during a 12-month follow-up, and 50 patients out of 60 of recurrent dysphagia during a 36-month follow-up. Seventy partially covered expandable metal stents were temporarily placed in the 70 patients of group B and withdrawn after 3-7 days via gastroscopy with complications of chest pain (n=28), reflux (n=15), and bleeding (n=9); 7 patients out of 70 exhibited dysphagia relapse during a 12-month follow-up, and 9 out of 58 patients exhibited dysphagia relapse during a 36-month follow-up. All the stents were inserted and withdrawn successfully. The follow-up in groups A-B lasted for 12-96 months. Conclusion Temporary partially covered metal stent dilation is one of the best methods of interventional procedure for achalasia in long-term follow-up.

Role of exosomal long non-coding RNAs in colorectal cancer

Exosomes are a class of small extracellular vesicles,30-150 nm in diameter,that transfer biological information(e.g.,DNA,RNA,and protein)via cell-to-cell communication.Exosomes play critical roles in the occurrence and development of human cancers,including colorectal cancer(CRC).Recent studies have shown that long non-coding RNAs(lncRNAs)can be encapsulated in exosomes,which transfer lncRNAs from secretory cells into recipient cells.This process affects the progression of CRC,since exosomal lncRNAs display special and extensive functions in CRC tumorigenesis,including malignant proliferation,metastasis,chemoresistance,and inflammatory response.Moreover,due to their specificity and sensitivity,exosomal lncRNAs are released into body fluids(e.g.,urine,sputum,and plasma),which have the potential to be biomarkers of CRC tumorigenesis within screening efforts and medical and epidemiologic research.In this review,we aim to clarify the function and mechanism of exosomal lncRNAs in CRC tumorigenesis and provide a strategy for early diagnosis and medical treatment of this malignancy.

Long-term outcomes in patients initially responsive to selective laser trabeculoplasty

AIMTo determine the long-term effects of selective laser trabeculoplasty (SLT) on intraocular pressure (IOP) and the number of medications used up to 5y following treatment in glaucoma patients receiving maximally tolerated medical therapy (MTMT).METHODSThe Wills Eye Hospital Glaucoma Research Center retrospectively reviewed the charts of glaucoma patients who underwent SLT after receiving MTMT. Eyes that did not achieve their target pressure within 3mo following SLT were excluded from the study. Changes in mean IOP and number of glaucoma medications used were analyzed at 1, 3, and 5y following SLT.RESULTSSeventy-five eyes of 67 patients were included in the study. Fifteen eyes that received SLT failed to achieve their target pressure within 3mo and were excluded from the study. The average follow-up time was 37.4mo (&#x000b1;14.4). Mean IOP was significantly reduced 1y after treatment (P=0.005). It was also reduced 3, 5y after treatment without reaching statistical significance (P=0.20 and P=0.072, respectively). There was a significant decrease in mean number of medications used 1, 3, 5y after treatment (P&#x0003c;0.001, P&#x0003c;0.001, and P=0.039, respectively). In the span of 5y, 2 eyes (2.7%) underwent repeat SLT, 7 eyes (9.3%) underwent glaucoma surgery and an additional 3 eyes (4.0%) underwent both.CONCLUSIONSLT significantly reduced the number of glaucoma medications used 5y following treatment in glaucoma patients receiving MTMT. SLT may delay operating-room surgery.
