Abstract
Periodontitis has been emphasized as a risk factor of insulin resistance-related systemic diseases. Accumulating evidence has suggested a possible "oral-gut axis" linking oral infection and extraoral diseases, but it remains unclear whether periodontal pathogens can survive the barriers of the digestive tract and how they play their pathogenic roles. The present study established a periodontitis mouse model through oral ligature plus Porphyromonas gingivalis inoculation and demonstrated that periodontitis aggravated diet-induced obesity and insulin resistance, while also causing P. gingivalis enrichment in the intestine. Metabolic labeling strategy validated that P. gingivalis could translocate to the gastrointestinal tract in a viable state. Oral administration of living P. gingivalis elicited insulin resistance, while administration of pasteurized P. gingivalis had no such effect. Combination analysis of metagenome sequencing and nontargeted metabolomics suggested that the tryptophan metabolism pathway, specifically indole and its derivatives, was involved in the pathogenesis of insulin resistance caused by oral administration of living P. gingivalis. Moreover, liquid chromatography-high-resolution mass spectrometry analysis confirmed that the aryl hydrocarbon receptor (AhR) ligands, mainly indole acetic acid, tryptamine, and indole-3-aldehyde, were reduced in diet-induced obese mice with periodontitis, leading to inactivation of AhR signaling. Supplementation with Ficz (6-formylindolo (3,2-b) carbazole), an AhR agonist, alleviated periodontitis-associated insulin resistance, in which the restoration of gut barrier function might play an important role. Collectively, these findings reveal that the oral-gut translocation of viable P. gingivalis works as a fuel linking periodontitis and insulin resistance, in which reduction of AhR ligands and inactivation of AhR signaling are involved. This study provides novel insight into the role of the oral-gut axis in the pathogenesis of periodontitis-associated comorbidities.

Evaluation of air quality changes in a Chinese megacity over a 15-year period (2006-2021) using PM 2.5 receptor modelling. Environ Pollut 2024; 340:122803.

Abstract
Air quality impairment has a massive impact on human health, with atmospheric particulate matter (PM) playing a major role. The People's Republic of China experienced a trend of increasing PM2.5 concentrations from 2000 to 2013. However, after the application of the Air Pollution Prevention and Control Action Plan and other related control measures, sharp decreases in air pollutant concentrations were particularly evident in the city of Wuhan (central China). This study analysed major changes in PM2.5 concentrations, composition and source apportionment (using receptor modelling) based on Wuhan's PM2.5 chemical speciation datasets from 2006 to 2007, 2019-2021 and contemporaneous gaseous pollutant values. Average SO2 concentrations decreased by 88%, from the first to the second period, mostly due to measures that reduced coal combustion. However, NO2 only declined by 25%, with policy measures likely being undermined by an increased number of vehicles. PM2.5 concentrations decreased by 65%, with the PM constituents each being affected differently. Coal combustion-related element concentrations, OC, SO42-, NH4+, EC, Cl-, Al, Ca, Cu, Fe, Co and NO3- decreased by 22-90%. Secondary inorganic aerosol (SIA) was initially dominated by (NH4)2SO4 (73%) in 2006, but later dominated by NH4NO3 (52%) in 2021. Receptor modelling identified major sources contributing to PM2.5: Mineral, road and desert dust (MRDD), Secondary sulphate (SECS), Secondary nitrate (SECN), Tungsten industry (W), Toxic Elements of Coal (TEC), Iron and Steel (IRONS), Coal Combustion (CC), Residential Heating (RH), Refinery (REF) and Traffic (TRF). In relative proportions, TEC (-83%), SECS (-64%) and SECN (-48%) reduced their contributions to PM2.5 whilst MRDD increased (+62.5%). Thus, the results indicate not only a drastic abatement of PM pollution in Wuhan but also a change in the sources of pollution, which requires further actions to reduce PM2.5 concentrations to health protective values. Secondary PM and fugitive emissions are key components to abate.

Abstract
BACKGROUND Worldwide, frozen embryo transfer (FET) has become a new strategy for the treatment of infertility. The success of FET is closely related to endometrial receptivity. Does uterine artery Doppler during the implantation window predict pregnancy outcome from the first FET? METHODS A total of 115 retrospectively collected cycles were included in the study, with 64 cycles of clinical pregnancy and 51 cycles of nonclinical pregnancy; There were 99 nonabsent end-diastolic flow (NAEDF) cycles and 16 absent end-diastolic flow (AEDF) cycles. The differences in uterine artery Doppler findings between different pregnancy outcomes were investigated. The clinical pregnancy rate and spontaneous abortion rate in the NAEDF and AEDF groups were compared. The predictive value of uterine artery Doppler during the implantation window in the success rate of pregnancy from the first FET was also investigated. RESULTS Between the clinical pregnancy group and the nonclinical pregnancy group, there were no significant differences in the mean resistance index (mRI) (Z = -1.065, p = 0.287), mean pulsatility index (mPI) (Z = -0.340, p = 0.734), and mean peak systolic/end-diastolic velocity(mS/D) (Z = -0.953, p = 0.341); there were significant differences in the mean peak systolic velocity (mPSV) (Z = -1.982, p = 0.048) and mean end-diastolic velocity (mEDV) (Z = -2.767, p = 0.006). Between the NAEDF and AEDF groups, there was no significant difference in the clinical pregnancy rate (χ2 = 0.003, p = 0.959), and there was a significant difference in the spontaneous abortion rate (χ2 = 3.465, p = 0.019). Compared with uterine artery Doppler alone, its combination with artificial abortion history, waist-to-hip ratio, LH (Luteinizing hormone) of P (Progesterone) administration day, mPSV and mEDV had a higher predictive value regarding clinical pregnancy from the first FET [ROC-AUC 0.782, 95% CI (0.680-0.883) vs. 0.692, 95% CI (0.587-0.797)]. CONCLUSIONS Uterine artery Doppler, particularly mPSV and mEDV during the implantation window, was useful for predicting clinical pregnancy, and AEDF was related to spontaneous abortion in the first trimester. Uterine artery Doppler combined with artificial abortion history, waist-to-hip ratio, LH of P administration day, mPSV and mEDV have a higher predictive value than uterine artery Doppler alone regarding the pregnancy from the first FET.

Abstract
BACKGROUND This study summarized the available randomized controlled trials (RCTs) to assess the efficacy and safety of macrolides on pathogens, lung function, laboratory parameters, and safety in children with bronchiectasis. METHODS PubMed, EMBASE, and the Cochrane Library were searched for available papers published up to June 2021. The outcomes were the pathogens, adverse events (AEs), and the forced expiratory volume in one second (FEV1%) predicted. RESULTS Seven RCTs (633 participants) were included. The long-term use of macrolides reduced the risk of the presence of Moraxella catarrhalis (RR = 0.67, 95% CI: 0.30-1.50, P = 0.001; I2 = 0.0%, Pheterogeneity = 0.433), but not Haemophilus influenza (RR = 0.19, 95% CI: 0.08-0.49, P = 0.333; I2 = 57.0%, Pheterogeneity = 0.040), Streptococcus pneumonia (RR = 0.91, 95% CI: 0.61-1.35, P = 0.635; I2 = 0.0%, Pheterogeneity = 0.515), Staphylococcus aureus (RR = 1.01, 95% CI: 0.36-2.84, P = 0.986; I2 = 61.9%, Pheterogeneity = 0.033), and any pathogens present (RR = 0.61, 95% CI: 0.29-1.29, P = 0.195; I2 = 80.3%, Pheterogeneity = 0.006). Long-term macrolides had no effect on FEV1% predicted (WMD = 2.61, 95% CI: -1.31, 6.53, P = 0.192; I2 = 0.0%, Pheterogeneity = 0.896). Long-term macrolides did not increase the risk of AEs or serious AEs. CONCLUSION Macrolides do not significantly reduce the risk of pathogens present (except for Moraxella catarrhalis) or increase FEV1% predicted among children with bronchiectasis. Moreover, macrolides were not associated with AEs. Considering the limitations of the meta-analysis, further larger-scale RCTs are needed to confirm the findings. IMPACT Macrolides do not significantly reduce the risk of pathogens present (except for Moraxella catarrhalis) among children with bronchiectasis. Macrolides do not significantly increase FEV1% predicted among children with bronchiectasis. This meta-analysis reports on the efficacy and safety of macrolides in the treatment of children with bronchiectasis, providing evidence for the management of children with bronchiectasis. This meta-analysis does not support the use of macrolides in the management of children with bronchiectasis unless the presence of Moraxella catarrhalis is provenor suspected.

Abstract
OBJECTIVE This study aimed to systematically evaluate the effect of whole-body vibration (WBV) training on the improvement of limb function in patients with Parkinson's disease (PD). MATERIALS AND METHODS An electronic search was performed on the databases, including PubMed, Web of Science, Scopus, SCI-hub, ScienceDirect, Embase, IEEE, Medline, Wiley, ClinicaIKey, CNKI, Wanfang, VIP database, Chinese Medical Association, and CBM Database from inception to May 2022 to collect randomized controlled studies on whole-body vibration training for patients with Parkinson's disease. Two researchers independently screened the literature, extracted the data, and evaluated the quality of the literature, then used ReviewManager 5.4 software for quantitative statistical analysis, including heterogeneity test, sensitivity analysis, risk of bias assessment, combined outcome index effect size and effect size inspection. RESULTS A total of 9 studies were included in the meta-analysis, including 346 patients, 174 patients in the control group and 172 patients in the observation group. Meta-analysis results showed that, compared with conventional physical therapy or drug therapy alone, whole-body vibration reduced the Unified Parkinson's Disease Rating Scale (UPDRSIII) score and significantly improved the motor function of patients with Parkinson's disease [MD=-2.39, 95% CI (-4.41, -0.37), Z=2.14 (p=0.23)]. Moreover, whole-body vibration significantly improved the walking stability of Parkinson's patients [MD=-1.96, 95% CI (-2.71-1.21), Z=1.17 (p=0.03)]. However, its improvement in balance ability [MD=-0.06, 95% CI (-0.77, 0.65), Z=1.07 (p=0.19)] and daily living ability [MD=0.03, 95% CI (-1.68, 0.74), Z=0.24 (p=0.87)] of patients, it was not t statistically significant. CONCLUSIONS Compared with conventional therapy, WBV has certain advantages in improving the balance function and gait performance of PD patients, but the effect on balance ability and daily living ability is not significant. Thus, more high-quality research is required for further verification.

Abstract
BACKGROUND Vascular endothelial growth factor receptor 2 (VEGFR2) plays a key role in antiangiogenesis which has been an essential strategy for cancer treatment. We report the first-in-human study of AK109, a novel anti-VEGFR2 monoclonal antibody, to characterize the safety profile and pharmacokinetics/pharmacodynamics (PK/PD) properties, and explore the preliminary antitumor efficacy in patients with solid tumors. PATIENTS AND METHODS This was a multicenter, open-label, phase I study, including dose escalation and dose expansion (NCT04547205). Patients with advanced cancers were treated 2 and 3 weekly with escalating doses of AK109. A 3 + 3 design was used to determine the maximum tolerated dose. Blood was sampled for PK/PD analysis. The primary endpoint was safety and recommended phase II dose (RP2D). RESULTS A total of 40 patients were enrolled. No dose-limiting toxicity was observed. However, 38 patients reported treatment-related adverse events (TRAEs); grade ≥3 TRAEs occurred in 10 patients. The most common TRAEs were proteinuria (n = 24, 60%), hypertension (n = 13, 32.5%), increased aspartate transaminase (n = 11, 27.5%), thrombopenia (n = 10, 25%), and anemia (n = 10, 25%). A total of 28 patients (70%) reported adverse events of special interest (AESIs). The most common AESIs were proteinuria (60%), hypertension (32.5%), and hemorrhage (32.5%), mainly including gum bleeding and urethrorrhagia. AK109 exhibited an approximately linear PK exposure with dose escalation at 2-12 mg/kg. PD analyses showed rapid target engagement. Among the 40 patients, 4 achieved partial response and 21 achieved stable disease with an objective response rate of 10% and a disease control rate of 62.5%. Based on the safety profile, the PK/PD profile, and preliminary antitumor activities, 12 mg/kg Q2W and 15 mg/kg Q3W were selected as RP2D. CONCLUSIONS AK109 showed manageable safety profile and promising antitumor activity, supporting further clinical development in a large population.

Abstract
PURPOSE Patients with tumor-induced osteomalacia (TIO) often suffer from irreversible height loss due to vertebral deformity. However, the prevalence of vertebral deformity in TIO patients varies among limited studies. In addition, the distribution and type of vertebral deformity, as well as its risk factors, remain unknown. This study aimed to identify the prevalence, distribution, type and risk factors for vertebral deformity in a large cohort of TIO patients. METHODS A total of 164 TIO patients were enrolled in this retrospective study. Deformity in vertebrae T4-L4 by lateral thoracolumbar spine radiographs was evaluated according to the semiquantitative method of Genant. Bone microstructure was evaluated by trabecular bone score (TBS) and high-resolution peripheral QCT (HR-pQCT). RESULTS Ninety-nine (99/164, 60.4%) patients had 517 deformed vertebrae with a bimodal pattern of distribution (T7-9 and T11-L1), and biconcave deformity was the most common type (267/517, 51.6%). Compared with patients without vertebral deformity, those with vertebral deformity had a higher male/female ratio, longer disease duration, more height loss, lower serum phosphate, higher bone turnover markers, lower TBS, lower areal bone mineral density (aBMD), lower peripheral volumetric BMD (vBMD) and worse microstructure. Lower trabecular vBMD and worse trabecular microstructure in the peripheral bone and lower spine TBS were associated with an increased risk of vertebral deformity independently of aBMD. After adjusting for the number of deformed vertebrae, we found little difference in clinical indexes among the patients with different types of vertebral deformity. However, we found significant correlations of clinical indexes with the number of deformed vertebrae and the spinal deformity index. CONCLUSION We reported a high prevalence of vertebral deformity in the largest cohort of TIO patients and described the vertebral deformity in detail for the first time. Risk factors for vertebral deformity included male sex, long disease duration, height loss, abnormal biochemical indexes and bone impairment. Clinical manifestation, biochemical indexes and bone impairment were correlated with the number of deformed vertebrae and degree of deformity, but not the type of deformity.

Abstract
A randomized, double-blind, placebo-controlled multicenter trial was conducted in healthy Chinese infants to assess the efficacy and safety of a hexavalent live human-bovine reassortant rotavirus vaccine (HRV) against rotavirus gastroenteritis (RVGE). A total of 6400 participants aged 6–12 weeks were enrolled and randomly assigned to either HRV (n = 3200) or placebo (n = 3200) group. All the subjects received three oral doses of vaccine four weeks apart. The vaccine efficacy (VE) against RVGE caused by rotavirus serotypes contained in HRV was evaluated from 14 days after three doses of administration up until the end of the second rotavirus season. VE against severe RVGE, VE against RVGE hospitalization caused by serotypes contained in HRV, and VE against RVGE, severe RVGE, and RVGE hospitalization caused by natural infection of any serotype of rotavirus were also investigated. All adverse events (AEs) were collected for 30 days after each dose. Serious AEs (SAEs) and intussusception cases were collected during the entire study. Our data showed that VE against RVGE caused by serotypes contained in HRV was 69.21% (95%CI: 53.31–79.69). VE against severe RVGE and RVGE hospitalization caused by serotypes contained in HRV were 91.36% (95%CI: 78.45–96.53) and 89.21% (95%CI: 64.51–96.72) respectively. VE against RVGE, severe RVGE, and RVGE hospitalization caused by natural infection of any serotype of rotavirus were 62.88% (95%CI: 49.11–72.92), 85.51% (95%CI: 72.74–92.30) and 83.68% (95%CI: 61.34–93.11). Incidences of AEs from the first dose to one month post the third dose in HRV and placebo groups were comparable. There was no significant difference in incidences of SAEs in HRV and placebo groups. This study shows that this hexavalent reassortant rotavirus vaccine is an effective, well-tolerated, and safe vaccine for Chinese infants. A multicenter, double-blind, phase III clinical trial for the efficacy and safety of hexavalent rotavirus vaccine (HRV). The vaccine efficacy against rotavirus gastroenteritis caused by serotypes contained in HRV was 69.21%. The efficacy against severe rotavirus gastroenteritis and hospitalization caused by serotypesin HRV were 91.36% and 89.21%. No significant difference between the incidences of adverse events and severe adverse events in HRV and placebo group. This hexavalent live human-bovine reassortant rotavirus vaccine iseffective, well tolerated and safe in Chinese infants.

Abstract
The study aims to explore the clinicopathological features and whether the nonsense mutations of CLCN5 gene have effect on the renal expression of CLC-5 protein and megalin/cubilin complex in children with Dent-1 disease. The clinicopathological features and genetic examination of three patients with Dent-1 disease were investigated. The expression of CLC-5 and megalin/cubilin complex in renal tissues was detected by using immunohistochemistry method. Urinary albumin, α1-microglobulin, β2-microglobulin, retinol binding protein, and calcium levels were measured by immunonephelometry. Urinary calcium and low molecular weight proteinuria (LMWP) were enhanced in three patients, and two presented with nephrotic range proteinuria. Focal glomerular obsolescence, minor tubulointerstitial injury, and focal calcification in corticomedullary junction were found in one patient. Nonsense mutations of CLCN5 gene from their mothers were identified in all three patients with Dent-1 disease; however, the expression of CLC-5 protein was not decreased in renal tubular cells. As the receptor complex of albumin and LMWP reabsorption, the expression of megalin/cubilin in the brush border of proximal tubules was decreased in Dent-1 patients. Even if the renal CLC-5 protein is expressed normally, the reduced expression of megalin/cubilin in the brush border of renal proximal tubules may be helpful to understand the physiopathology of Dent-1 disease with nonsense mutations of CLCN5 gene.

Abstract
Noninvasive prenatal testing (NIPT) for monogenic disorders has been developed in recent years; however, there are still significant technical and analytical challenges for clinical use. The clinical feasibility of NIPT for methylmalonic acidemia cblC type (cblC type MMA) was investigated using our circulating single-molecule amplification and re-sequencing technology (cSMART). Trios molecular diagnosis was performed in 29 cblC type MMA-affected children and their parents by traditional Sanger sequencing. In the second pregnancy, invasive prenatal diagnosis (IPD) of the pathogenic MMACHC gene was used to determine fetal genotypes, and NIPT was performed using a novel MMACHC gene–specific cSMART assay. Maternal–fetal genotypes were deduced based on the mutation ratio in maternal plasma DNA. Concordance of fetal genotypes between IPD and NIPT, and the sensitivity and specificity of NIPT were determined. After removing two cases with a low P value or reads, the concordance ratio for NIPT and IPD was 100.00% (27/27), and the sensitivity and specificity were 100.00% (54.07–100.00%) and 100.00% (83.89–100.00%), respectively. This study demonstrates that NIPT using the cSMART assay for cblC type MMA was accurate in detecting fetal genotypes. cSMART has a potential clinical application as a prenatal diagnosis and screening tool for carrier and low-risk genotypes of cblC type MMA and other monogenic diseases.

Abstract
Radiomic features are being increasingly studied for clinical applications. We aimed to assess the agreement among radiomic features when computed by several groups by using different software packages under very tightly controlled conditions, which included standardized feature definitions and common image data sets. Ten sites (9 from the NCI's Quantitative Imaging Network] positron emission tomography–computed tomography working group plus one site from outside that group) participated in this project. Nine common quantitative imaging features were selected for comparison including features that describe morphology, intensity, shape, and texture. The common image data sets were: three 3D digital reference objects (DROs) and 10 patient image scans from the Lung Image Database Consortium data set using a specific lesion in each scan. Each object (DRO or lesion) was accompanied by an already-defined volume of interest, from which the features were calculated. Feature values for each object (DRO or lesion) were reported. The coefficient of variation (CV), expressed as a percentage, was calculated across software packages for each feature on each object. Thirteen sets of results were obtained for the DROs and patient data sets. Five of the 9 features showed excellent agreement with CV < 1%; 1 feature had moderate agreement (CV < 10%), and 3 features had larger variations (CV ≥ 10%) even after attempts at harmonization of feature calculations. This work highlights the value of feature definition standardization as well as the need to further clarify definitions for some features.

Abstract
AIM To analyse the efficacy and safety of endothelin receptor antagonists for people with diabetic kidney disease. METHODS Randomized controlled trials comparing endothelin receptor antagonists with placebo in people with diabetic kidney disease were identified through PubMed, Embase and the Cochrane Library. We used a random-effect model to calculate the mean difference or risk ratio with the 95% CI. RESULTS Seven studies with a total of 4730 participants were included. Overall, endothelin receptor antagonists significantly reduced albuminuria compared with placebo (standardized mean difference -0.48, 95% CI -0.64 to -0.33). Atrasentan, in particular, effectively reduced albuminuria (standardized mean difference -0.58, 95% CI -1.00 to -0.17) and the risk of composite renal endpoints (risk ratio 0.65; 95% CI 0.49 to 0.88), with insignificant change in the rate of congestive heart failure (risk ratio 1.40, 95% CI 0.76 to 2.56) and mortality (risk ratio 1.11, 95% CI 0.77 to 1.61). In contrast, although avosentan reduced albuminuria (standardized mean difference -0.47, 95% CI -0.57 to -0.36) and the risk of composite renal endpoints (risk ratio 0.63, 95% CI 0.42 to 0.94), it was associated with a significant increase in congestive heart failure risk (risk ratio 2.61, 95% CI 1.36 to 5.00) and an insignificant increase in mortality risk (risk ratio 1.50, 95% CI 0.81, 2.78). No significant change in efficacy or safety outcomes with bosentan was detected. Dose-response analysis indicated that 0.75 mg/day atrasentan is expected to be optimal for renoprotection, with maximal albuminuria reduction and minimal fluid retention events. CONCLUSIONS Among the endothelin receptor antagonists, atrasentan and avosentan, but not bosentan, are effective for renoprotection in people with diabetic kidney disease. Compared with other types and doses, atrasentan 0.75 mg/day is the most promising, with maximal albuminuria reduction and minimal fluid retention. Vigilant monitoring of congestive heart failure risk is needed in future clinical practice. (PROSPERO registration no. CRD42020169840).

Abstract
OBJECTIVE We hope it will provide a reference for early detection, early diagnosis, and early treatment of atypical Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis with non-typical autonomic dysfunctions as the first symptom. PATIENTS AND METHODS We present a 15-year-old girl with the repetition of conscious disturbance at different levels, but no abnormal movements. Initially, there were no positive findings on routine electroencephalography (EEG) and dynamic video-electroencephalography (V-EEG), but the head-up tilt test (HTT) suggested neurocardiogenic syncope (vascular rejection type), which seemed to be the final diagnosis. However, the patient later experienced several episodes of disturbance of consciousness with unexplained abdominal pain. Abnormalities were discovered on EEG, which indicated the possibility of "epileptic seizures with autonomic-gastrointestinal features". Based on these findings, we finally tested the autoimmune encephalitis-related antibodies for the patient after the literature search and review. RESULTS The patient was finally diagnosed with anti-NMDAR encephalitis. Her symptoms were fully controlled after glucocorticoid and gamma globulin treatment, and she left the hospital with complete recovery. CONCLUSIONS Although autonomic nervous dysfunction occurred in our patient, her prognosis was good because she did not have respiratory or (and) circulatory failure. Exclusive diagnosis and early treatment are important in patients with anti-NMDAR encephalitis. Abdominal pain with positive HTT may be a manifestation of autonomic dysfunction in this disease.

Abstract
OBJECTIVE The aim of this study was to detect the relationship between long-chain non-coding RNA (lncRNA) NEAT1 and microRNA-1224 (miR-1224) in lung cancer and to explore its underlying mechanism. MATERIALS AND METHODS The expression levels of lncRNA NEAT1 and miR-1224 in lung cancer tissues and cells were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The interaction between lncRNA NEAT1 with miR-1224, miR-1224, and KLF3 was detected by Dual-Luciferase Reporter Gene Assay. MTT 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide and flow cytometry were used to detect the changes in the proliferative and apoptosis abilities of lung cancer cells after silencing lncRNA NEAT1 or up-regulating miR-1224, respectively. RESULTS Compared with adjacent normal tissues, lncRNA NEAT1 was significantly up-regulated, while miR-1224 was significantly down-regulated in lung cancer tissues. LncRNA NEAT1 could specifically bind to the 3'UTR of miR-1224 and regulate its expression. The inhibition of lncRNA NEAT1 remarkably reduced the proliferation and enhanced the apoptosis of lung cancer cells. However, the upregulation of the expression of miR-1224 level could significantly inhibit proliferation and promote the apoptosis rate of lung cancer cells. Furthermore, miR-1224 could downregulate KLF3 expression by directly binding to its 3'UTR. CONCLUSIONS LncRNA NEAT1 can sponge the expression of miR-1224, thereby affecting the proliferation and apoptosis of lung cancer.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) is a heterogeneous disease with different clinical characteristics and different treatment responsiveness. The aims of this study were to compare the nasal fluid cytology and cytokines between eosinophilic CRSwNP (eCRSwNP) and non-eosinophilic CRSwNP (neCRSwNP) and establish a new multivariate model to predict eCRSwNP before surgery to improve personalized treatment for CRSwNP patients. METHODS Eighty-six consecutive patients with CRSwNP and sixteen healthy controls were recruited in this study. Nasal fluid (NF) was collected from all subjects and nasal polyp tissue was collected during the surgery. The differential cell counts and concentrations of IL-6, IL-8, TNF-77; and IL-10 in NF were measured. Univariate and multivariate logistic regression were used to identify predictors for eCRSwNP. RESULTS There were more inflammatory cells in NF of CRSwNP than controls. The eosinophil percentage was significantly higher in eCRSwNP than neCRSwNP and controls. The level of IL-8 was significantly higher in neCRSwNP than in eCRSwNP and controls. Blood eosinophilia, nasal fluid eosinophilia, higher total ethmoid score / total maxillary score (E/M ratio) and higher visual analogue scale (VAS) score of CRS were associated with eCRSwNP, the area under receiver operating characteristic curve (AUC) was 0.800, 0.755, 0.703 and 0.648, respectively. Using the coefficients of multivariate regression, we set up a scoring system to predict eCRSwNP with three of the variates and the AUC was 0.883. CONCLUSION ECRSwNP, neCRSwNP and healthy controls demonstrated different cytology and cytokine profiles in NF. A new preoperational multivariate prediction model for eCRSwNP with NF eosinophilia, blood eosinophilia and higher E/M ratio was established.

Abstract
OBJECTIVE To evaluate the clinical feasibility of noninvasive prenatal diagnosis (NIPD) for β-thalassaemia using circulating single molecule amplification and re-sequencing technology (cSMART). DESIGN Through carrier screening, 102 pregnant Chinese couples carrying pathogenic HBB gene variants were recruited to the study. Pregnancies were managed using traditional invasive prenatal diagnosis (IPD). Retrospectively, we evaluated the archived pregnancy plasma DNA by NIPD to evaluate the performance of our cSMART assay for fetal genotyping. SETTING Chinese prenatal diagnostic centres specialising in thalassaemia testing. POPULATION Chinese carrier couples at high genetic risk for β-thalassaemia. METHODS Fetal cell sampling was performed by amniocentesis and HBB genotypes were determined by reverse dot blot. NIPD was performed by a newly designed HBB cSMART assay and fetal genotypes were called by measuring the allelic ratios in the maternal cell-free DNA. MAIN OUTCOME MEASURES Concordance of HBB fetal genotyping between IPD and NIPD and the sensitivity and specificity of NIPD. RESULTS Invasive prenatal diagnosis identified 29 affected homozygotes or compound heterozygotes, 54 heterozygotes and 19 normal homozygotes. Compared with IPD results, 99 of 102 fetuses (97%) were correctly genotyped by our NIPD assay. Two of three discordant samples were false positives and the other sample involved an incorrect call of a heterozygote carrier as a homozygote normal. Overall, the sensitivity and specificity of our NIPD assay was 100% (95% CI 88.06-100.00%) and 97.26% (95% CI 90.45-99.67%), respectively. CONCLUSIONS This study demonstrates that our cSMART-based NIPD assay for β-thalassaemia has potential clinical utility as an alternative to IPD for pregnant HBB carrier couples. TWEETABLE ABSTRACT A new noninvasive test for pregnancies at risk for β-thalassaemia.

Abstract
Background Echinococcosis is a chronic zoonosis caused by tapeworms of the genus Echinococcus. Treatment of the disease is often expensive and complicated, sometimes requiring extensive surgery. Ultrasonographic imaging is currently the main technique for diagnosis, while immunological analysis provides additional information. Confirmation still needs pathological analysis. However, these diagnostic techniques generally detect infection in late stages of the disease. An accurate, early and non-invasive molecular diagnostic method is still unavailable. Methodology/Principal findings We sequenced the cell-free DNA (cfDNA) from plasma of echinococcosis patients and confirmed the presence of Echinococcus DNA. To improve detection sensitivity, we developed a method based on targeted next-generation sequencing of repeat regions. Simulation experiments demonstrate that the targeted sequencing is sensitive enough to detect as little as 0.1% of an Echinococcus genome in 1 mL of plasma. Results obtained using patient plasma shows that the Area Under the Curve (AUC) of the method is 0.862, with a detection sensitivity of 62.50% and specificity of 100%, corresponding to a Youden-index of 0.625. Conclusions/Significance This study provides evidence that hydatid cysts release cfDNA fragments into patient plasma. Using the repeat region targeted sequencing method, highly specific detection of Echinococcus infection was achieved. This study paves a new avenue for potential non-invasive screening and diagnosis of echinococcosis. Echinococcosis is a severe chronic parasitic disease caused by tapeworms of the genus Echinococcus. According to the World Health Organization, there are more than 1 million people living with echinococcosis worldwide. For decades, little progress has been made to develop a molecular diagnosis and specific treatment for the disease. Although imaging and immunological detection are used for diagnosis, these technologies are either only effective for late stages of the disease or hardly conclusive. The detection of cell-free DNA has been a powerful tool for precise diagnosis. In this study, we showed the presence of Echinococcus-derived cell-free DNA in plasma of echinococcosis patients. We further established an assay to detect parasite DNA in blood samples based on amplification of Echinococcus specific repeat regions followed by targeted next-generation sequencing. This technique provides a new method for potential extensive screening and precision diagnosis of echinococcosis with high specificity.

Abstract
OBJECTIVE To explore the correlation between change in sclerostin level and heart valve calcification in patients with chronic kidney disease (CKD) in stages 3-5, as well as the possible underlying mechanism, which could provide a clinical reference for the diagnosis and treatment of cardiovascular disease (CVD). PATIENTS AND METHODS 110 patients were divided into a healthy control group and three groups of patients with CKD stages 3, 4, and 5 according to CKD staging guidelines. Scr, BUN, AKP, TC, TG, HDL, LDL, Ca, Pi, and CRP were measured, and calcium-phosphate product (Ca×Pi) calculated. ELISA was used to measure the sclerostin level, and the estimated glomerular filtration rate (eGFR) was calculated by MDRD. Heart valve calcification was measured by a physician in the Cardiac Department of our hospital. The correlations between sclerostin-level change and heart valve calcification, as well as each index in CKD patients in stages 3-5, were analyzed. RESULTS Compared with the healthy control group, the serum Ca in CKD stage-3, stage-4, and stage-5 groups (p < 0.05) was reduced, and PTH was increased (p < 0.05). Blood Pi and Ca×Pi in the stage-4 and stage-5 groups were increased (p < 0.05). The serum sclerostin level increased with renal hypofunction in stage-3 CKD patients, and was significantly increased compared with that of the control group, reaching the highest level in the terminal stage (p < 0.01). Pearson correlation analysis indicated that serum sclerostin was negatively correlated with eGFR (r = -0.91, p < 0.001) and blood Ca (r= -0.271, p < 0.001), and positively correlated with SCr (r = 0.608, p < 0.001), blood Pi level (r = 0.295, p < 0.001), PTH (r = 0.334, p < 0.001), and Ca×Pi (r = 0.275, p < 0.001). The rate of heart valve calcification in the CKD patients in stage 5 was relatively high (11/30, 36.67%), and significantly higher than that in healthy controls (1/20, 5%; p < 0.01). Logistic regression analysis of heart valve calcification indicated that sclerostin was a risk factor for heart valve calcification in CKD patients in stages 3-5. CONCLUSIONS The sclerostin level gradually increased with renal hypofunction in CKD patients in stages 3-5, and the increase in serum sclerostin level in the CKD patients occurred earlier than the change in Pi and Ca×Pi. The risk of heart valve calcification in stage-5 CKD patients was significantly increased. Sclerostin is an independent risk factor for heart valve calcification in CKD patients.

Abstract
OBJECTIVE Long noncoding RNA LINC00675 (LINC00675) seems to play an anti-oncogenic role in cancers, though its exact function remains unknown. Up to date, little is known about the role of LINC00675 in esophageal squamous cell carcinoma (ESCC). In this study, we aimed to explore the expression pattern, clinical significance and biological function of LINC00675 in ESCC. PATIENTS AND METHODS RT-PCR was performed to detect the expression levels of LINC00675 in both ESCC tissue and cell lines. The association of LINC00675 expression with clinicopathological factors and prognosis was statistically analyzed. Cell growth was detected by MTT assay and colony formation assay. Cell apoptosis was evaluated with flow cytometry. Migration and invasion ability of ESCC cells were detected wound healing assay and transwell assays. The expressions of EMT-related proteins and Wnt/β-catenin-related proteins by Western blot were investigated. RESULTS LINC00675 expression was significantly downregulated in both ESCC tissues and cell lines. Decreased LINC00675 expression was correlated with histological grade, lymph nodes metastasis and advanced clinical stage. Furthermore, LINC00675 could serve as an independent predictor for overall survival in ESCC. Importantly, in vitro experiments indicated that that forced LINC00675 expression significantly suppressed inhibited ESCC cell proliferation, colony formation, migration, invasion and EMT, and promoted cell apoptosis through suppressing Wnt/β-catenin signaling pathway. CONCLUSIONS We suggested that LINC00675 acted as a tumor suppressor in ESCC via regulation of Wnt/β-catenin signaling pathway and may be a new prognostic biomarker and potential therapeutic target for ESCC intervention.

Abstract
OBJECTIVE To develop a technique for non-invasive prenatal diagnosis of spinal muscular atrophy and validate its performance. STUDY DESIGN Pregnant women with 1 copy of SMN1 and male fetuses were enrolled. Seventeen women were included in test set A, and 10 of them were selected into test set B randomly and blinded. The two sets were tested independently by two different researchers blinded to fetal genotypes. Fetal DNA fractions were calculated based on the relative proportion of mapped chromosome Y sequencing reads. An algorithm was developed to decide fetal SMN1 copy numbers. RESULTS The concordance rate with the results of MLPA testing of amniocyte DNA was 94.12% in test set A and 90% in set B. For all tests with a classifiable result, the percent of agreement with the results of MLPA testing of amniocyte DNA was up to 100% (25/25). CONCLUSION We have developed a direct, rapid, and low-cost technique, which has a potential to be utilized for first-trimester non-invasive prenatal diagnosis and screening for spinal muscular atrophy with considerable reliability and feasibility.

Abstract
OBJECTIVE Recently, the vital role of circular RNAs is discovered in many diseases, including tumor progression. Hepatocellular carcinoma (HCC) is one of the most ordinary malignant tumors. The purpose of our study is to detect the potential function of circ_0000885 in HCC to offer new biomarkers and targets. PATIENTS AND METHODS The expression level of circ_0000885 in HCC tissues and cell lines was monitored by Real Time-quantitative Polymerase Chain Reaction (RT-qPCR). Pearson's Chi-square test was used to determine the association of circ_0000885 expression with several clinicopathological factors. Then knockdown of circ_0000885 was constructed to uncover its function in HCC. The cell growth ability was measured through the cell counting kit-8 (CCK-8) assay, colony formation assay, and cell cycle assay. The Western blot assay was performed to analyze the protein level of Caprin1. RESULTS Circ_0000885 was highly expressed in HCC tissues than that in adjacent samples. The miR-532-5p expression was associated with lymphatic metastasis and TNM stage. The expression of circ_0000885 was also higher in HCC cell lines. The cell growth ability of HCC cells was inhibited after circ_0000885 was silenced. Furthermore, Caprin1 was inhibited via knockdown of circ_0000885. CONCLUSIONS Circ_0000885 could enhance cell proliferation and regulate cell cycle of HCC by promoting Caprin1.

Abstract
OBJECTIVE To assess the diagnostic performance of a novel circulating single molecule amplification and re-sequencing technology (cSMART) method for noninvasive prenatal testing (NIPT) of Phenylketonuria (PKU). DESIGN Blinded NIPT analysis of pregnancies at high risk for PKU. SETTING Shanghai Xinhua Hospital and Hunan Jiahui Genetics Hospital, China. POPULATION Couples (n = 33) with a child diagnosed with PKU. METHODS Trio testing for pathogenic PAH mutations was performed by Sanger sequencing. In second pregnancies, invasive prenatal diagnosis (IPD) was used to determine fetal genotypes. NIPT was performed using a PAH gene-specific cSMART assay. Based on the plasma DNA mutation ratio relative to the fetal DNA fraction, fetal genotypes were assigned using a maximum-likelihood algorithm. MAIN OUTCOME MEASURES Concordance of fetal genotyping results between IPD and NIPT, and the sensitivity and specificity of the NIPT assay. RESULTS Compared with gold standard IPD results, 32 of 33 fetuses (96.97%) were accurately genotyped by NIPT. The sensitivity and specificity of the NIPT assay was 100.00% (95% CI 59.04-100.00%) and 96.15% (95% CI 80.36-99.90%), respectively. CONCLUSIONS The novel cSMART assay demonstrated high accuracy for correctly calling fetal genotypes. We propose that this test has useful clinical utility for the rapid screening of high-risk and low-risk pregnancies with a known history of PKU on one or both sides of the family. TWEETABLE ABSTRACT NIPT of couples at high risk for PKU using a full-coverage cSMART PAH gene test.

Abstract
OBJECTIVE To study the efficacy of transarterial chemoembolization (TACE) combined with high-intensity focused ultrasound (HIFU) in patients with middle-advanced liver cancer. PATIENTS AND METHODS A total of 100 patients with middle-advanced liver cancer treated in our hospital from January 2015 to January 2018 were selected and randomly divided into TACE group (control group, n=50) and TACE combined with HIFU group (experimental group, n=50) according to different therapeutic regimens. The efficacy was observed after the operation, the blood was collected to detect the postoperative liver function indexes aspartate aminotransferase (AST) and alanine aminotransferase (ALT), the postoperative complications were observed. Also, the immune indexes cluster of differentiation 3+ (CD3+), CD4+, and CD8+ were determined. Moreover, the quality of life (QOL) score was compared between the two groups, the 1-, 2-, 3-, and 5-year survival rates were observed after the operation. Also, the changes in the levels of tumor markers α-L-fucosidase (AFU), alpha-fetoprotein (AFP), carbohydrate antigen 19-9 (CA19-9), and carcinoembryonic antigen (CEA) were observed. RESULTS In experimental group, the levels of AST, ALT, and blood urea nitrogen (BUN) after the operation were significantly decreased (p<0.05), while the postoperative efficacy was significantly superior to that in control group (p<0.05). The incidence of postoperative complications was significantly reduced (p<0.05), the levels of CD3+, CD4+, CD8+, and natural killer (NK) cells were markedly increased (p<0.05). Also, the QOL score was evidently better than that in control group (p<0.05) and the 1-, 2-, 3-, and 5- year survival rates after the operation were evidently higher than those in control group (p<0.05). After treatment, the levels of AFU, AFP, CA19-9, and CEA were remarkably lower than those before treatment in both groups, while they were remarkably lower in experimental group than those in control group (p<0.05). CONCLUSIONS TACE combined with HIFU in the treatment of patients with middle-advanced liver cancer can restore the hepatic metabolism, enhance the immunity, improve the QOL, prolong the survival time of patients, and significantly reduce the tumor markers. Also, it has fewer adverse reactions and definite overall efficacy, which is worthy of popularization and application.

Abstract
Chrysophanol (CHR), a purified active constituent extracted from Rheum palmatum L., possesses anti-inflammatory activity. This study aimed to evaluate its effects on asthma-associated airway inflammation and remodeling. BALB/c mice were sensitized and challenged by ovalbumin (OVA) and administrated with different doses of CHR. We found that CHR decreased OVA-induced pulmonary inflammation: the levels of interleukin (IL)-4, IL-5, and IL-13, tumor necrosis factor (TNF)-α, and inducible nitric oxide synthase were downregulated. CHR also attenuated airway remodeling induced by OVA challenge-CHR inhibited pulmonary α-smooth muscle actin expression. Moreover, both the nuclear translocation and activity of NF-κB p65 were inhibited by CHR in the asthmatic lung. Enhanced autophagy was initiated in the lung by OVA challenge as evidenced by upregulated light chain 3 beta, autophagy-related protein 5, and Beclin 1. CHR suppressed OVA-induced alterations in these autophagy-related molecules. In vitro, CHR (2 or 20 μM) was used to treat human pulmonary epithelial BEAS-2B cells in the presence of 10 ng/ml recombinant TNF-α. CHR not only exhibited the antiproliferation effect but also inhibited the activation of nuclear factor-kappa B (NF-kB) signaling pathway in TNF-α-treated BEAS-2B cells. In conclusion, our study indicates that CHR has the potential to ameliorate asthma.

Abstract
RATIONALE Hereditary multiple exostoses (HMEs) is an autosomal dominant skeletal disorder. PATIENT CONCERNS Six probands of the 6 unrelated Han Chinese families were identified as having HME. These patients had exostoses at multiple sites and significantly affected joints malformation and movement. DIAGNOSES Hereditary multiple exostoses. INTERVENTIONS To detect the genetic mechanism of HME in 6 unrelated Chinese families, whole-exome sequencing (WES) and multiplex ligation-dependent probe amplification (MLPA) were used after genomic DNA was isolated from peripheral blood leucocytes. Point mutations identified by these methods were verified by Sanger sequencing after PCR amplification. OUTCOMES Six mutations in the EXT1 and EXT2 genes were identified, including a heterozygous deletion mutation from exon 2 to exon 8 (Family 1), a c.448C>T, p.(Gln150X) heterozygous nonsense mutation (Family 4), a c.1057-2A>T heterozygous splicing substitution (Family 5), and a c.1468dupC, p.(Leu490fs519X) (Family 6) heterozygous duplication mutation in the EXT1 gene in addition to a heterozygous deletion mutation from exon 2 to exon 3 (Family 2) and a c.1197C>G, p.(Tyr399X) heterozygous nonsense mutation (Family 3) in the EXT2 gene. LESSONS Overall, we identified 5 novel mutations and 1 recurrent mutation in the EXT1 and EXT2 genes in 6 Chinese families with HME. Our findings expand the mutational spectrum of the EXT1 and EXT2 genes and are useful for genetic counseling and prenatal diagnosis.

Abstract
Autosomal recessive cornea plana is a very rare hereditary ocular disease, characterized by a flattened corneal curvature, marked hyperopia due to low refractive power and frequently consequent accommodative esotropia. Other features include various cornea anterior segment abnormalities, without systemic problems. The purpose of the present study was to investigate the clinical and molecular alterations in a Chinese family with cornea plana. Full ophthalmic examinations of the patients were performed, including slit-lamp examination, fundus examination and ocular ultrasound. Whole-exome sequencing data were screened for pathological variants in the proband, which were confirmed by Sanger sequencing. One novel missense mutation, c.242A>G (p.N81S) and another novel 7 base-pair deletion mutation, c.772-779del (p.G258Cfs*30), were detected in the keratocan (KERA) gene; two affected siblings inherited these variations in a compound heterozygous state, which were derived from the clinically unaffected heterozygous father (c.772_779del) and mother (c.242A>G), respectively. Neither mutation was observed in unrelated healthy controls (n=200). Multiple computer software predictions supported the pathogenicity of the two variants. Furthermore, protein modeling prediction was performed to better understand the molecular basis of cornea plana, particularly the importance of the leucine-rich repeat domain. This study presents the 14th pathogenic KERA mutations identified worldwide and the first in East Asia so far, to the best of our knowledge. These findings guided prenatal diagnosis for the family in question and expand on the variant spectrum of KERA, therefore facilitating genetic counseling.

Abstract
Purpose To detect the underlying pathogenesis of congenital cataract in a four-generation Chinese family. Methods Whole-exome sequencing (WES) of family members (III:4, IV:4, and IV:6) was performed. Sanger sequencing and bioinformatics analysis were subsequently conducted. Full-length WT-MIP or K228fs-MIP fused to HA markers at the N-terminal was transfected into HeLa cells. Next, quantitative real-time PCR, western blotting and immunofluorescence confocal laser scanning were performed. Results The age of onset for nonsyndromic cataracts in male patients was by 1-year old, earlier than for female patients, who exhibited onset at adulthood. A novel c.682_683delAA (p.K228fs230X) mutation in main intrinsic protein (MIP) cosegregated with the cataract phenotype. The instability index and unfolded states for truncated MIP were predicted to increase by bioinformatics analysis. The mRNA transcription level of K228fs-MIP was reduced compared with that of WT-MIP, and K228fs-MIP protein expression was also lower than that of WT-MIP. Immunofluorescence images showed that WT-MIP principally localized to the plasma membrane, whereas the mutant protein was trapped in the cytoplasm. Conclusions Our study generated genetic and primary functional evidence for a novel c.682_683delAA mutation in MIP that expands the variant spectrum of MIP and help us better understand the molecular basis of cataract.

Abstract
This meta-analysis compared the efficacy and safety of the contact force (CF)-sensing catheter and second-generation cryoballoon (CB) ablation for treating atrial fibrillation (AF). Six controlled clinical trials comparing ablation for AF using a CF-sensing catheter or second-generation CB were identified from PubMed, EMBASE, Cochrane Library, Wanfang Data, and China National Knowledge Infrastructure. The procedure duration was significantly lower in the CB group compared with that in the CF group [mean difference (MD)=29.4; 95%CI=17.84–40.96; P=0.01], whereas there was no difference between the groups for fluoroscopy duration (MD=0.59; 95%CI=–4.48–5.66; P=0.82). Moreover, there was no difference in the incidence of non-lethal complications (embolic event, tamponade, femoral/subclavian hematoma, arteriovenous fistula, pulmonary vein stenosis, phrenic nerve palsy, and esophageal injury) between the CB and the CF groups (8.38 vs 5.35%; RR=0.66; 95%CI=0.37–1.17; P=0.15). Transient phrenic nerve palsy occurred in 17 of 326 patients (5.2%) of the CB group vs none in the CF group (RR=0.12; 95%CI=0.03–0.43; P=0.001). A comparable proportion of patients in CF and CB groups suffered from AF recurrence during the 12-month follow-up after a single ablation procedure [risk ratio (RR)=1.03; 95%CI=0.78–1.35; P=0.84]. AF ablation using CF-sensing catheters and second-generation CB showed comparable fluoroscopy duration and efficacy (during a 12-month follow-up), with shorter procedure duration and different complications in the CB group.

Abstract
Sclerosing stromal tumor (SST) is a rare ovarian neoplasia deriving from the sex cord stromal tumor, which occurs usually in the sec- ond and third decades of life. However, the authors report a 46-year old multiparous woman who presented with a cystic-solid left pelvic mass, a large amount of ascites, and elevated serum CA-125, all suggesting a malignant tumor. Surgery was performed and final histopathological diagnosis of the specimen was diagnosed with SST. The authors herein report an extremely rare case of SST with a cystic-solid pelvic mass and a large amount of ascites, which is useful to demonstrate the possibility of SST in multiparous woman.

Abstract
BACKGROUND Hirschsprung's disease (HSCR) is one of the common digestive disorders in the new born. Long non-coding RNAs (lncRNAs) play an important role in various biological processes. However, knowledge on lncRNAs in HSCR is limited. METHODS The expression profile of lncRNAs in HSCR was obtained using microarray. A total of 2078 differentially expressed lncRNAs were detected by microarray in HSCR tissues compared with matched normal colon tissues (fold change ≥2, p < 0.05). Candidate biomarkers were selected from these differentially expressed lncRNAs based on artificial criterion (raw signal intensity ≥50; fold change ≥8) and then validated in 80 pairs of HSCR and normal tissues using quantitative real-time polymerase chain reaction (qRT-PCR). Moreover, the computational analysis was used to evaluate the lncRNA-microRNA and lncRNA-protein relationships. KEY RESULTS A panel of 5-lncRNAs was identified to distinguish HSCR from normal tissues with remarkable sensitivity and specificity. The area under the receiver operating characteristic curve (AUC) for HSCR identification in the validation set was 0.875. The bioinformatics analysis reveals that these dysregulated lncRNAs are mainly involved in RNA-protein relationships, including RNA splicing, binding, transport, processing, and localization. CONCLUSIONS & INFERENCES Our results are the first to report the expression profile of dysregulated lncRNAs in HSCR and infer that lncRNAs may serve as novel diagnostic biomarkers for HSCR.

Abstract
Deep infiltrating endometriosis (DIE) is a complex disorder that affects 6% to 12% of all women in the reproductive age. In these cases, treatment is more difficult with possible incomplete pain relief and a considerable possibility of recurrence. Here, the authors report a case of a 41-year-old woman with a history of severe dysmenorrhea, dyspareunia, and chronic pelvic pain because of deep infiltrating pelvic and peritoneal endometriosis, who underwent segmental colorectal resection three years ago for large bowel obstruction due to colonic endometriosis. To ensure complete removal of the disease, the authors injected gonadotropin-releasing hormone agonist (GnRHa) in three periodic cycles before laparoscopic surgery. We performed laparoscopic hysterectomy and deep pelvic nodule resection and pelvic adhesion releasing. After five days of hospitalization, the patient recovered totally and was not experiencing any pain at three months' follow-up. Laparoscopic treatment has more become the standard of treatment for DIE. A review of the literature regarding pathology and physiology of DIE and surgical aspects of its management is undertaken. The authors would like to renew the current laparoscopic surgery in curing the DIE, as they believe that this is also a useful addition to the literature.
