RESUMO

OBJECTIVE: To investigate the implementation of schistosomiasis control activities in China during the coronavirus disease 2019 (COVID-19) epidemic, so as to evaluate the impact of COVID-19 epidemic on the national schistosomiasis control program in China. METHODS: On April 2020, 3 counties (districts) were randomly selected from each of the 12 schistosomiasis-endemic provinces (municipality, autonomous region), and a questionnaire survey was conducted to investigate the implementation of schistosomiasis control activities in these counties (districts) from January to March 2020. Then, the impact of the COVID-19 epidemics on the national schistosomiasis control program of China was evaluated using a comparative analysis approach. RESULTS: Among the 36 counties (cities, districts) sampled from 12 provinces (municipality, autonomous region), 66.67% were at a high and medium risk of COVID-19 epidemics. The implementation of schistosomiasis control activities assignment, human schistosomiasis examination and treatment, snail control with chemical treatment and health education reduced by 44.26% to 91.56% as compared to 2019 during the same time period, and the schistosomiasis control program was more affected by COVID-19 in transmission-controlled provinces. The gross funds invested into the schistosomiasis control program reduced by 23.39% in relative to the expected, while the total expenditure increased by 41.22%. In addition, all 36 surveyed counties (districts) considered that the COVID-19 epidemic had a short-term impact on the schistosomiasis control program, with the most predominant impact on schistosomiasis control activities assignment, human resources and monitoring of endemic situation of schistosomiasis. CONCLUSIONS: The COVID-19 epidemics affect the routine schistosomiasis control program across the endemic-foci of China. Policy and financial support should be strengthened to ensure the completion of the schistosomiasis control program.

RESUMO

BACKGROUND: HCC as the 6th most common tumor entity with the fourth highest mortality and an increasing prevalence especially due to today's lifestyle acquires a high attention in the clinical setting. Beside CECT and CEMRI, CEUS depicts a dynamic, low-risk and radiation free imaging method that finds its use mainly in screening and active surveillance programs. PURPOSE: The aim of the retrospective study was to evaluate the diagnostic value of CEUS in correlation to pathologic findings. MATERIALS AND METHODS: Between 2004 and 2018 a total number of 119 patients were included in this retrospective single-center study. Every patient underwent CEUS in addition to a native B-mode and Color-Doppler scan. After given informed consent SonoVue® (Bracco, Milan, Italy), a second-generation blood-pool agent, was used as contrast medium. Every examination was performed and interpreted by a single experienced radiologist (EFSUMB level 3). A low mechanical index (MI) of <0,2 was chosen to obtain a good imaging quality. RESULTS: All 119 included patients received CEUS followed by a renal biopsy for inter-modality comparison. In correlation to the pathology results, CEUS showed a diagnostic sensitivity of 96,6%, a specificity of 63,9%, a PPV of 86,7% and a NPV of 88,5% by detecting liver lesions suspicious for HCC. According to the Cohen's Kappa coefficient (k = 0,659) CEUS shows a strong inter-modality agreement in comparison to the histopathological finding. CONCLUSION: With a high sensitivity and a strong cross-modality comparability to histopathology, the CEUS is highly effective in the detection of suspicious HCC lesions.

RESUMO

Objectives: To explore changes in the quality of life(QoL)in patients with non-severe aplastic anemia(NSAA)after 2 years of cyclosporine A(CsA)therapy, and possible factors may affect the QoL. Methods: Patients with de novo NSAA from January 2014 to 2016 who had been treated with only CsA for at least 2 years in the outpatient department of Peking Union Medical College Hospital were instructed to fill-in the SF-36 form before and after 2 years of CsA treatment. Data from NSAA were compared with those of normal controls; patients' information such as age, sex, education, annual income, type of payment, and compliance were collected, disease severity and response to treatment were also evaluated. Results: A total of 52 patients were included in our study with 27(51.9%)men and 25(48.1%)women, with the medium age of 48(21-85)years. After 2 years of treatment, 15(28.8%)patients achieved complete response(CR), 25(48.1%)achieved partial response(PR), and 12(23.1%)patients had no response(NR). The overall response rate(ORR)was 76.9%. Before the therapy, SF-36 scores in patients with NSAA were significantly lower than that of normal controls either in physical or mental component summaries(P<0.05). However, after 2 years of therapy, patients with NSAA had significant improvement of mental component summaries and recovered to normal with even higher scores in mental health(MH)(65.9±17.6 vs 59.7±22.9, P=0.014)and energy/vitality(VT)(58.8±20.1 vs 52.3±20.9, P=0.023)compared with normal controls, although they still had comparatively lower scores in physical component summaries. No associations were found between QoL and age, sex, educational level, family income, type of payment, patient adherence, or transfusion dependency. Patients with higher ECOG (the Eastern Cooperative Oncology Group score)at the beginning experienced greater progress in QoL compared to those with lower ECOG. Both patients with CR and PR had shown significant improvement in QoL. Conclusion: Patients with NSAA had impaired QoL compared with normal patients. CsA treatment can improve the QoL, especially in mental component summaries. Patients can benefit from the treatment regardless of their social status, and patients with lower ECOG at the beginning seem to benefit more from the therapy.

RESUMO

Objective: To compare the clinical characteristics and outcomes of patients newly diagnosed with multiple myeloma(NDMM)with bone-related extramedullary(EM-B)disease and those with extraosseous extramedullary(EM-E)disease and to address their prognostic factors. Methods: The clinical features, outcomes, and prognostic factors were retrospectively analyzed in 80 patients with NDMM with extramedullary disease. Results: Among 80 patients with extramedullary disease, 51 had EM-B and 29 EM-E. The level of ß(2)-microglobulin(5.82 mg/L vs 3.99 mg/L, P=0.030), lactate dehydrogenase(256 U/L vs 184 U/L, P=0.003), 1q21 amplification rate(78.6% vs 53.1%, P=0.035), and Ki-67 proliferation index(50% vs 25%, P=0.002)in the EME group were significantly higher than those in the EM-B group. The posieive rate of CD56(14.3% vs 66.7%)and overall response rate(60% vs 82.3%)in EM-E group were significantly lower than those in EM-B group. The median overall survival (OS)of patients with EM-E and EM-B was 14.5 and 49.5 months, and the median progression-free survival(PFS)of the two groups was 9.0 and 18.0 months. Patients with EM-E had a significantly shorter OS(P=0.035)and PFS(P < 0.001)than those of patients with EM-B, whereas the PFS did not significantly differ(P=0.263)when patients accepted proteasome inhibitor(PI)-based regimens for induction therapy. Multivariate analysis with Cox model showed the best response that did not achieve partial response(PR)was an independent poor prognostic factor for both OS and PFS in NDMM patients with EM-E(P=0.031, P=0.005), ISS-III, and the best response that did not achieve PR were independent prognostic factors for the shorter OS in patients with NDMM with EM-B(P=0.009, P=0.044). Conclusions: The clinical characteristics and outcomes of patients with NDMM with EM-E are different from patients with EM-B. Outcomes of patients with EM-E is significantly poor. PI induction therapy improved the PFS of patients with EM-E.

RESUMO

AIM: To investigate the diagnostic efficacy of the contrast-enhanced ultrasound Liver Imaging Reporting and Data System (CEUS LI-RADS) for categorising hepatic observations in patients at risk of hepatocellular carcinoma (HCC) compared with magnetic resonance imaging (MRI) LI-RADS. MATERIALS AND METHODS: CEUS and MRI data were analysed retrospectively according to the LI-RADS scheme. Follow-up results and pathological findings served as the reference standard. Receiver operating characteristic (ROC) curve analysis was used to reveal the area under the curve (AUC). The sensitivity, specificity, accuracy, and positive (PPV) and negative predictive values (NPV) of LR-5 for determining HCC were calculated. The intra-observer agreement of CEUS LI-RADS was also evaluated. RESULTS: Eighty-four patients with 86 liver observations were enrolled. Forty-two observations were classified as LR-5 by CEUS and MRI, respectively. Based on the reference standard, 53 nodules were HCC. The AUCs were 0.876 for CEUS and 0.873 for MRI, without a significant difference (Z=0.050, p=0.960). The sensitivity, specificity, PPV, NPV, and accuracy of LR-5 was 75.47%, 93.94%, 95.24%, 70.45%, 82.56% with CEUS and 73.58%, 90.9%, 92.86%, 68.18%, 80.23% with MRI, respectively. There was a significant difference in specificity between CEUS and MRI (p=0.006). There was almost perfect agreement for arterial phase hyperenhancement (k=0.870), substantial agreement for washout (k=0.765) and CEUS LI-RADS category (k=0.787). CONCLUSION: The CEUS LI-RADS scheme is an effective diagnostic tool for HCC with substantial intra-observer reliability. The diagnostic performance of CEUS LI-RADS for determining HCC was comparable to MRI LI-RADS, and the specificity of CEUS LR-5 was significantly higher.

RESUMO

OBJECTIVE: To evaluate the impact of the flood disaster on schistosomiasis transmission along the Yangtze River basin in 2020, so as to provide insights into schistosomiasis prevention and control in flood-affected areas. METHODS: The data pertaining to the endemic situation of schistosomiasis were collected from 5 provinces of Hunan, Hubei, Jiangxi, Anhui and Jiangsu from 2013 to 2019, including Schistosoma japonicum infections in humans and livestock and snail distribution, and the warning water levels and actual water status were collected in water regions locating in these 5 provinces. The cumulative numbers of S. japonicum egg-positive individuals and bovines during the period from 2013 to 2019, the area of snail habitats in 2019 and the water level on July 12, 2020 were estimated at a county level and employed as parameters for classification of schistosomiasis transmission risk. Then, the cumulative value of each risk index was calculated to assess the risk of schistosomiasis transmission risk. RESULTS: After the flood disaster along the Yangtze River basin in 2020, there were 10, 5 and 9 counties (districts) at high risk of schistosomiasis transmission in 5 provinces of Hunan, Hubei, Jiangxi, Anhui and Jiangsu based on number of egg-positive individuals, number of egg-positive bovines and snail distribution, respectively. Based on comprehensive risk indices, there were 10 (8 in Dongting Lake regions of Hunan Province and 2 in Poyang Lake regions of Jiangxi Province) and 15 counties (districts) (4 in Hubei Province, 7 in Hunan Province and 4 in Jiangxi Province) identified at grades 5 and 4 risk of schistosomiasis transmission. CONCLUSIONS: Dongting Lake regions and Poyang Lake regions are the most severely flood-affected schistosomiasis-endemic foci of China in 2020, and the flood disaster may facilitate the transmission of schistosomiasis in affected areas. Therefore, schistosomiasis control requires to be intensified after the flood disaster to prevent the rebound of the disease.

RESUMO

To determine the effects of normal and low dietary calcium (Ca) and phosphorus (P) levels and 25-hydroxycholecalciferol (25-OH-D3) supplementation on performance, serum antioxidant status, meat quality, and bone properties of broilers, 224 1-day-old Arbor Acre male broilers were used in this study. Broilers were allotted randomly to 1 of 4 treatments in a 2 × 2 factorial arrangement that included normal or low Ca and P diet with or without 69 µg/kg 25-OH-D3. The trial consists of a starter phase from day 1 to 21 and a grower phase from day 22 to 42. Dietary 25-OH-D3 supplementation increased (P < 0.05) average daily weight gain from day 22 to 42 and decreased feed conversation ratio from day 22 to 42 and day 0 to 42. On day 21, 25-OH-D3 increased serum concentrations of total antioxidant capacity (T-AOC), catalase (CAT), and glutathione peroxidase in broilers fed low Ca and P diet (Interaction, P < 0.05). 25-hydroxycholecalciferol significantly decreased serum malondialdehyde concentration. Dietary Ca and P deficiencies significantly decreased serum Ca and P concentrations and increased serum parathyroid hormone (PTH) concentration, and serum Ca and 25-OH-D3 concentrations were significantly increased by 25-OH-D3 supplementation. On day 42, serum T-AOC and CAT concentrations were decreased by dietary Ca and P deficiencies without 25-OH-D3 (Interaction, P < 0.05) and unaffected by dietary Ca and P deficiencies with 25-OH-D3. Dietary Ca and P deficiencies significantly decreased Ca, P, and alkaline phosphatase concentrations and increased PTH concentration in serum. Dietary 25-OH-D3 increased (P < 0.05) serum Ca and 25-OH-D3 concentrations and decreased (P < 0.05) serum tartrate-resistant acid phosphatase concentration. The interaction between CaP level and 25-OH-D3 was observed (P < 0.05) for tibial Ca content and femoral bone density. 25-hydroxycholecalciferol significantly increased tibial breaking strength. These data indicated that 25-OH-D3 supplementation at 69 µg/kg increased growth performance in some periods, enhanced serum antioxidant capacity, and improved bone mineralization and breaking strength of broilers.

RESUMO

To investigate the effects of dietary taurine supplementation on growth performance, antioxidant status, and lipid metabolism in broilers, 384 male broilers (Arbor Acres, 1 D of age) were randomly allocated into 4 groups with 8 replicates of 8 birds. Dietary treatments were supplemented with taurine at the level of 0.00, 2.50, 5.00, and 7.50 g/kg of the diet (denoted as CON, TAU1, TAU2, TAU3, respectively). The BW gain from 1 to 21 D and from 22 to 42 D were all increased linearly (linear, P < 0.001) by taurine supplementation. Throughout the trial period, the highest BW gain and favorable gain-to-feed ratio were observed in the TAU2 group. Taurine supplementation increased the antioxidant enzyme activities and decreased (linear, P < 0.001) the content of malondialdehyde in both serum and the liver of broilers and alleviated oxidative damage through enhancing (P < 0.05) the hepatic genes expression of nuclear factor erythroid-2-related factor 2 (NRF2), glutathione peroxidase (GPX), and heme oxygenase-1 (HO-1). Correspondingly, in serum, the activities of hepatic lipase and total lipase were decreased linearly and quadratically (linear and quadratic, P < 0.001) with the increasing inclusion of taurine in the diet. Meanwhile, in serum, the content of triglycerides was significantly decreased (P < 0.05), and except for TAU3, the total cholesterol content was also significantly decreased (P < 0.05) by taurine supplementation. In addition, the hepatic content of triglycerides was significantly decreased (P < 0.05) in the TAU1 and TAU2 groups. Compared with the CON group, the hepatic genes expression of adenosine monophosphate-activated protein kinase alpha (AMPKα), silent 1, (SIRT1) and carnitine palmitoyltransferase 1 (CPT-1) were all increased (P < 0.05), and sterol regulatory element-binding protein-1 (SREBP-1) expression was decreased (P < 0.05) in the TAU2 group. These results indicated that taurine supplementation improved the growth performance, antioxidant capacity, and lipid metabolism of broilers.

RESUMO

Objective To understand the effects and clinical significance of the 2019 guidelines for the human epidermal growth factor receptor 2 (HER2) detection. Methods: According to the 2014 guidelines, 548 cases of invasive breast cancer with equivocal HER2 (2+) detected by immunohistochemistry (IHC) in Taizhou Enze Medical Center, Zhejiang Province, China from 2013 to 2019 were selected. The results of IHC and HER2/CEPl7 double-probe were reevaluated and divided into groups according to the 2019 guidelines for the comparative analysis. Results: Among the 548 IHC HER2 (2+) invasive breast cancers, the number of positive, equivocal and negative cases for HER2 were 96 (17.52%), 81 (14.78%) and 371 (67.70%), respectively, according to the 2014 guidelines. However, according to the 2019 guidelines, 10 cases (1.82%) were reclassified as IHC 1+, 2 cases in the group 2 were reclassified as negative, and all the originally equivocal cases in group 4 were reclassified as negative. Finally, the total number of positive and negative cases for HER2 were 94 (17.15%) and 454 (82.85%), respectively. Conclusions: After applying the 2019 guidelines, the number of IHC 2+ cases decreases, and the positive rate for HER2 also decreases slightly due to the reevaluation change in groups 2 and 4, leading to reclassification of the cases that were deemed equivocal according to the 2014 guidelines. In general, the new 2019 guidelines are more reasonable and easier to use.

RESUMO

Objective: To investigate the long-term clinical efficacy and safety of the bilateral superior oblique tendon suture spacer in treatment of A-pattern strabismus with superior oblique overaction (SOOA). Methods: Retrospective case series study. Twenty-one A-pattern strabismus patients who received the quantitative bilateral superior oblique tendon suture spacer with a complete follow-up from January 2009 to August 2017 were enrolled. Among these patients, 19 were exotropic and 2 were esotropic, including 11 males and 10 females, aged (14±9) years. Patients with unilateral superior oblique overaction, Broun syndrome or Helveston syndrome were excluded. The A-pattern strabismus, objective torsion, function of the superior oblique muscle and binocular vision were examined pre-and post-operatively. Paired t-test was used for normal distribution data, Wilcoxon rank-sum test was used for non-normal distribution data, Spearman rank correlation test and simple linear regression were used to analyze the correlation between the two variables. Results: The follow-up was 12 to 109 months (mean, 26±17 months). Twenty patients showed good alignment in the primary position with a deviation angle less than 10 prism diopter (PD), and 1 patient with esotropia had an angle greater than 15 PD. All the patients had no A pattern after surgery. The average pre-and post-operative A-patterns were (23.81±9.47) PD and (0.90±3.59) PD (t=11.29, P<0.01), respectively, and the average corrected A pattern was (23.52±9.68) PD.The average pre-and post-operative torsion was 3.18°±3.26° and -4.81°±4.13° (t=8.87, P<0.01), espectively, and the average corrected torsion was 7.95°±3.88°. No patient complained of torsional diplopia after surgery. The average amount of pre-and post-operative SOOA was 3.0 (2.0) and 0.0 (1.0) in 42 eyes (Z=-5.78, P<0.01), respectively. Suture extension of the superior oblique tendon was related with the pre-operative SOOA (r=0.47, P<0.01), but was not related with the pre-operative torsion (r=0.02, P=0.88). The linear regression results was suture extension=2.71× the grade of pre-operative SOOA (t=27.93, P<0.01). Conclusions: The bilateral superior oblique tendon suture spacer can improve the A-pattern, objective torsion and SOOA, with no torsional diplopia or V pattern after the long-term follow-up. It is a safe and effective superior oblique muscle weakening procedure. (Chin J Ophthalmol, 2020, 56: 853-858).

RESUMO

AIM: Podocytes dysfunction including the cell integrity, apoptosis and inflammation plays crucial role in diabetic nephropathy. Current exploration evaluated the protective role of eicosapentaenoic acid (EPA) in high glucose-treated podocytes and the underlying mechanisms. METHOD: MPC5 cell were stimulated by high glucose or treated by EPA of different concentrations. CCK8 assay was utilized to assess MPC5 cell viability, flow cytometry analyzed cell apoptosis. RESULTS: Data showed that EPA prominently alleviated the high glucose-induced apoptosis and inflammation. Besides, the disruption of the podocytes structure certifying by podocin and synaptopodin induced by hyperglycemia was hindered by EPA administration. In addition, overexpression of the sterol regulatory element-binding protein-1 (SREBP-1) reversed the protective effects of EPA in high glucose-treated podocytes. EPA inhibits the SREBP-1/TLR4/MYD88 signaling in high glucose treated cells. CONCLUSIONS: This study suggests that EPA protects against podocytes dysfunction by regulating SREBP-1 and these findings provide a better understanding for diabetic nephropathy and a novel therapeutic strategy (Fig. 7, Ref. 24).

RESUMO

Objective: To evaluate the effect and safety of laparoscopic cholecystectomy (LC) on the treatment of patients with gallbladder cancer (GBC), compared with patients undergoing open cholecystectomy (OC). Methods: PubMed, EMBASE, Web of Science, CNKI, CQVIP and WANFANG DATA and the Cochrane Library were searched for all Chinese and English literatures of randomized or non-randomized concurrent controlled trials of OC and LC treatment of GBC from the database establishment to March 2020. Two reviewers selected the studies according to inclusion and exclusion criteria, extracted the data, and then a meta-analysis was subsequently performed by the RevMan 5.3 software provided by the Cochrane Library. Results: A total of 15 studies (1 074 patients) including 14 retrospective studies and 1 prospective study met the inclusion criteria. The meta-analysis showed that compared with OC, LC has significant short-term efficacy in the treatment of patients with gallbladder cancer, including shorter operation time (mean difference (MD) =-18.78, 95% confidence interval (CI) : -36.68-0.88; P=0.04), less intraoperative blood loss (MD=-166.57, 95%CI: -248.51--84.63; P<0.000 1), shorter post-operative hospital stays (MD=-5.00, 95%CI: -6.43--3.57; P<0.000 1), less complication rate (OR=0.47, 95%CI: 0.28-0.79; P=0.004), but there was no significant difference on the aspects of recurrence rate (OR=0.48, 95%CI: 0.21-1.11; P=0.09), 5-year overall survival (HR=0.93, 95%CI: 0.54-1.61, I2=33.5%, P=0.198) and long-term survival. Conclusion: Whether it is radical cholecystectomy (RC) or simple cholecystectomy (SC), the short-term efficacy of LC is more significant than that of OC, and the long-term survival rate has no significant statistical difference. Limited by the quality of literature and experiments, the above conclusions still need to be supported by higher quality research.

RESUMO

Objective: The storage of medical data has been digitized in China, but a unified and structured model has not yet been established. The standardized collection, analysis and sorting of tumor clinical data is the foundation of improving the standard of tumor diagnosis and treatment. Therefore, establishing a database platform of gastric cancer (GC) is an urgent need to integrate data resources and improve the level of diagnosis and treatment. The population economics indexes of GC patients in the last 20 years are analyzed in a single-center GC database. The medical records were structured by natural language processing technology. Authors aim to investigate the clinical pathological characteristics, staging and survival of the GC patients with gastrectomy. Method: A retrospective cohort study was carried out. Clinicopatological data of patients receiving surgical treatment from 2000 to 2019 were retrospectively collected. According to the gastric cancer TNM staging guidelines from the Union for International Cancer Control and the American Joint Committee on Cancer (UICC/AJCC) 8th edition, the structured gastric cancer clinicopathological data were re-evaluated and interpreted. The Kaplan-Meier method and the log-rank test were used to compare survival rate among different groups of patients with complete follow-up data of 2010-2016. Results: Clinicopathological data of 13 492 GC patients were enrolled. The ratio of men to women in the whole group was 3.25:1.00, including 10 320 men with average onset age of 59.68 years, which was basically stable in recent 20 years, and 3172 women with average onset age of 55.93 years, which presented a trend of average increasement of 0.17 year per year. The average hospitalization duration for GC patients showed a decreasing trend year by year, which was 13.87 days in 2019. Average hospitalization cost for GC patients was increasing year by year, with a peak of 83 600 CNY in 2017 and 75 400 CNY in 2019. By natural language identification and exclusion criteria screening, a total of 7218 GC patients obtained structured clinicopathological information. Analysis on clinicopathological characteristics of 3626 GC patients in the last 5 years showed that the average diameter of tumor was (4.44±2.61) cm; the average number of harvested lymph node was 24.30±13.29; the proportion of surgical methods were as following: open surgery in 1398 cases (38.55%), laparoscopic surgery in 1856 cases (51.19%) and robotic surgery in 372 cases (10.26%). The postoperative pathological stage was as following: IA in 658 cases (18.15%), IB in 318 cases (8.77%), IIA in 559 cases (15.42%), IIB in 543 (14.98%), III A in 632 (17.43%), III B in 612 cases (16.88%), III C in 276 cases (7.61%), and IV in 28 cases (0.77%).

RESUMO

OBJECTIVE: LncRNA HCG11 has been confirmed to act as a crucial role in several human cancers. Nevertheless, to our knowledge, the function of HCG11 on the progression of ovarian cancer (OC) has not been studied. This article is designed to explore the mechanism and role of HCG11 in the tumorigenesis and development of OC. PATIENTS AND METHODS: RT-qPCR analysis was applied to detect the expression of HCG11, miR-144-3p and PBX3 in OC tissues and cell lines. MTT assay and transwell assay were opted to measure the cell viability of OC cells. The protein expression level of PBX3 was measured by Western blot assay. Dual-Luciferase reporter assay was carried out to assess the correlation between HCG11, miR-144-3p and PBX3. RESULTS: The upregulated of HCG11 was observed in OC tissues and OC cell lines. Moreover, miR-144-3p was down expressed in OC tissues and cell lines. Functionally, the knockdown of HCG11 prevented cell viability of SKOV3 cells, while miR-144-3p inhibitor abrogated the suppressor on cell progression. Furthermore, PBX3 was verified to be a target gene of miR-144-3p. In addition, PBX3 knockdown prevented the cell progression of SKOV3 cells. CONCLUSIONS: These data displayed that the knockdown of HCG11 prevented cell progression in OC by sponging miR-144-3p and downregulating PBX3. All results revealed that HCG11 can be a potential therapeutic target for OC therapy.

RESUMO

Genes associated with the WNT pathway play an important role in the etiology of tooth agenesis. Low-density lipoprotein receptor-related protein 6 encoding gene (LRP6) is a recently defined gene that is associated with autosomal dominant inherited tooth agenesis. Here, we aimed to identify novel LRP6 mutations in patients with tooth agenesis and investigate the significance of Lrp6 during tooth development. Using whole-exome sequencing, we identified 4 novel LRP6 heterozygous mutations (c.2292G>A, c.195dup, c.1095dup, and c.1681C>T) in 4 of 77 oligodontia patients. Notably, a patient who carried a nonsense LRP6 mutation (c.2292G>A; p.W764*) presented a hypohidrotic ectodermal dysplasia phenotype. Preliminary functional studies, including bioinformatics analysis and TOP-/FOP-flash reporter assays, demonstrated that the activation of WNT/ß-catenin signaling was compromised as a consequence of LRP6 mutations. RNAscope in situ hybridization revealed dynamic and special changes of Lrp6 expression during murine tooth development from E11.5 to E16.5. It was noteworthy that Lrp6 was specifically expressed in the epithelium at E11.5 to E13.5 but was expressed in both dental epithelium and dental papilla from E14.5 and persisted in both tissues at later stages. Our study broadens the mutation spectrum of human tooth agenesis and is the first to identify a LRP6 mutation in patients with hypohidrotic ectodermal dysplasia and reveal the dynamic expression pattern of Lrp6 during tooth development. Information from this study is conducive to understanding the functional significance of Lrp6 on the biological process of tooth development.

RESUMO

BACKGROUND: Colorectal cancer (CRC) has emerged as a major public health concern. However, little is known about the burden attributable to specific risk factors. The present study aimed to estimate the temporal trends and geographical variation of CRC burden attributable to a diet low in milk in China. METHODS: Following the general analytic strategy used in the 2017 Global Burden of Disease study, we assessed the age-, sex-, and province-specific mortality and disability-adjusted life-years (DALYs) of CRC caused by a diet low in milk in China from 1990 to 2017. RESULTS: In 2017, a diet low in milk contributed 32 032 [95% uncertainty interval (UI) = 11 350-53 806] deaths and 726 710 (95% UI = 256 651-1 218 153) DALYs for CRC with a population attributable fraction of 17.1%. The age-standardised mortality and DALY rates per 100 000 were 1.7 (95% UI = 0.6-2.9) and 36.8 (95% UI = 13.0-61.7), respectively. An upward trend with age in rates of mortality and DALYs was observed. Males had higher age-standardised rates than females. The number of deaths and DALYs increased significantly from 1990 to 2017, whereas the corresponding age-standardised rates showed relatively stable trends. In 2017, Hunan and Liaoning were ranked as the top two provinces in terms of disease burden. Socio-demographic index had a weak correlation with the age-standardised mortality (r = 0.348, P = 0.047). CONCLUSIONS: The present study shows a substantial increase in the CRC burden attributable to a diet low in milk over the past three decades. Greater priority in CRC prevention should be given to males and the elderly population throughout China, particularly in less-developed provinces.

RESUMO

Objective: To summarize the etiology and surgical treatment experience of tricuspid valve disease due to permanent pacemaker lead. Methods: The medical records of 22 patients who underwent tricuspid valve operation for tricuspid valve disease due to permanent cardiac pacemaker lead from January 2008 to December 2017 were retrospectively reviewed. There were 12 males and 10 females, with a mean age of (62.6±12.1) years old (45-82 years old). All patients underwent tricuspid valve surgery via open thoracotomy under general anesthesia, including 8 patients through median thoracotomy approach, 4 patients through right mini-thoracotomy approach, and 10 patients with endoscopy-assisted and totally endoscopic technique. Moreover, 8 patients underwent tricuspid valve replacement, and 14 patients received tricuspid valve repair. Results: During the operation, 10 cases of severe tricuspid regurgitation were detected due to valve and subvalvular structures dysfunction involved in the pacing electrode, 7 cases showed tricuspid annulus dilation, and pacing electrode-related infective endocarditis were involved in the tricuspid valve of 5 cases. Compared with conventional median thoracotomy surgery, the amount of postoperative drainage fluid and hospitalization time after minimally invasive surgery (including right mini-thoracotomy and endoscopic surgery) were significantly reduced [281(120, 489) ml vs 368(180, 560) ml, P=0.02; 9.2(4.8, 14.5) d vs 11.2(6.3, 16.9) d, P=0.03]. Postoperative echocardiographic data showed that the size of the right atrium and ventricle in these patients was significantly reduced compared with preoperative data, and their cardiac function were normal. There was no difference of pacing electrode parameters between pre-and postoperative period. All 22 patients were cured and discharged, with no valve-and pacemaker-related complications. Conclusions: Patients with tricuspid valve disease due to permanent cardiac pacemaker lead should actively undergo surgery including tricuspid replacement or repair according to different etiologies, which exhibit satisfactory outcomes. Minimally invasive endoscopic tricuspid surgery is a new technique for the treatment of isolated tricuspid valve disease, with less surgical trauma and faster recovery.
