Abstract
BACKGROUND Oral and dental disease is a major cause of long-term morbidity following allogeneic blood and marrow transplantation (Allo-BMT). This study aimed to describe the extent and range of oral and dental complications in BMT recipients and to identify gaps in service provision provided to this high-risk group. METHODS Participants were Allo-BMT recipients, aged >18 years, and received transplants between 2000 and 2012 in NSW. They completed seven surveys, the purpose-designed Sydney Post-BMT Study survey and six other validated instruments. RESULTS Of 441 respondents, many reported dry mouth (45.1%), dental caries (36.7%), mouth ulcers (35.3%), oral GVHD (35.1%), gingivitis (16.2%), tooth abscess (6.1%) and oral cancer (1.5%). Regular dental visits were reported by 66.2% of survivors. Middle-high income, older age and geographic location showed a positive association with regular dental visits. Of those who did not visit the dentist regularly, 37% stated they did not feel it necessary, 36% reported cost and 20% stated it was not advised by the treating team. CONCLUSION Despite oral complications commonly occurring after Allo-BMT, many survivors receive inadequate dental care. These results emphasize the need for improved oral health education, the importance of regular dental checks and improvement in the delivery of dental health services for BMT survivors.

Abstract
AIM To evaluate the technical feasibility and treatment results of ultrasound (US)-guided percutaneous radiofrequency ablation (RFA) combined with ethanol ablation (EA) for hepatocellular carcinoma (HCC) in the caudate lobe. MATERIALS AND METHODS The institutional review board approved this retrospective study and the requirement for informed consent was waived. From October 2009 to June 2016, there were 49 patients with HCC in the caudate lobe underwent ablation. Among them, 14 patients (12 men and two women, mean age: 49.9±14.9 years) with 16 caudate lobe HCCs (mean size: 3±1.1 cm) who underwent US-guided RFA-EA were identified. These patients were compared with patients who underwent RFA alone (n=17) and EA alone (n=18). RESULTS HCCs in the RFA-EA group were larger than those in the EA-alone group (3±1.1 versus 2.1±0.7 cm, p=0.028). In the RFA-EA group, all the patients achieved treatment success (14/14) and entered follow-up. After a follow-up period of 17.1±10.6 months (range, 5-36 months), local tumour progression (LTP) was detected in four tumours. The 1- and 2-year LTP rates after RFA-EA were 18.8% and 27.8%, respectively. The 1- and 2-year disease-free survival (DFS) rates were 35.7% and 13.4%. Six patients died, with the 1-, 2-, and 3-year overall survival (OS) rates of 85.1%, 63.1%, and 21%, respectively. There were no significant differences in the LTP, DFS, and OS rates between the RFA-EA group and RFA-alone or EA groups (p=0.363-0.733). CONCLUSION US-guided percutaneous RFA-EA appears to be a feasible and effective treatment for HCC in the caudate lobe.

Abstract
The aim of the study was to investigate the effect of immunosuppression therapy early after kidney transplantation, particularly exposure of mycophenolic acid (MPA) and calcineurin inhibitor (CNI), on posttransplantation de novo HLA antibody production. METHODS A single-center retrospective cohort study was performed at the First Affiliated Hospital of Sun Yat-sen University, enrolling the kidney transplant or pancreas-kidney transplant recipients who had surgery between January 2010 and February 2016. RESULTS A total of 214 recipients were included in the study with a median follow-up period of 1.06 years. A total of 30 recipients (14.0%) were positive in HLA antibody detection posttransplant with a median follow-up period of 1.46 years. Ten recipients (4.7%) lost their allograft function during follow-up, and 6 of them (60%) developed de novo HLA antibody after graft failure. Multivariate analysis showed that acute rejection significantly increased the risk of de novo HLA antibody (hazard ratio [HR], 2.732). Intensified MPA dosing therapy reduced the risk by 59.8% (HR, 0.402); low-dose CNI therapy increased the risk by 33.3% (HR, 1.333), and the effect of extremely low-dose CNI therapy was even larger (HR, 2.242). CONCLUSION The risk of de novo HLA antibody can be decreased by reducing the risk of acute rejection. A tendency was seen in low-dose CNI therapy to increase the risk of de novo HLA antibody, but intensified MPA dosing therapy may provide an umbrella protection effect by reducing the risk. Prospective study was required to confirm the effects.

Abstract
Objective: To discuss the application of three dimentional(3D)visualization technologies in treatment plan of hepatic malignant tumor. Methods: The clinical data of 300 patients with liver malignant tumor who received treatment from January 2016 to January 2017 in the Third Department of Hepatic Surgery of Eastern Hepatobiliary Surgery Hospital was retrospectively analyzed in this study, including 221 male and 79 female patients aged from 7 to 76 years with median age of 54 years. The median height was 168 cm (115-183 cm), the median weight was 65 kg (20-105 kg) and the median tumor volume was 142 ml (23-2 493 ml). Three-dimensional visualization technology was used in all patients to reconstruct liver three-dimensional graphics. Also, two and three-dimensional methods were taken respectively to evaluate patients and develop treatment strategy. The change of treatment strategy caused by 3D evaluation, actual surgical plan, operation time, time of hepatic vascular occlusion, intraoperative blood loss, volumes of blood transfusion and postoperative complications was observed. Results: After three-dimensional visualization technology was applied, 75(25%) of 300 patients' treatment strategies had been changed. The range of hepatectomy was extended in 25 patients. And 7 of them were due to hepatic venous variation, which resulted in increasing drainage area. In other 4 patients, liver resections were extended due to lack of perfusion of the liver parenchyma after the removal of portal vein. And hepatectomy was expanded in 14 patients in order to increase the surgical margin. The range of hepatectomy was reduced in 8 patients, 4 of which were due to hepatic venous variation, such as hepatic vein of segment 4 or lower right posterior hepatic vein. The remaining 4 cases were because of insufficient residual liver volume.The surgical resection was performed in 278 cases, 257 of which received operation directly. Left hepatectomy was performed in 24 patients and right hepatectomy was performed in 33 patients. Left trisectionectomy was carried out in 12 patients and right trisectionectomy was carried out in 11 patients. Caudate lobectomy was applied in 10 patients. There were 18 cases of left lateral sectionectomy, 7 cases of right anterior sectionectomy, 25 cases of right posterior sectionectomy and 18 cases of mesohepatectomy. Single or multi segment resection was performed in 99 patients. The treatment strategy of thirty-six patients was converted to staged hepatectomy (ALPPS 11 cases and portal vein embolization 25 cases). The median operation time was 130 minutes (90-360 minutes) and the median inflow blood occlusion time was 20 minutes (0-75 minutes). Median blood loss volume was 200 ml (20-1 600 ml). Thirty-seven of 278 patients received transfusions, and the average red blood transfusion volume was (4.4±1.7)units (0-8 units). Median hepatic resection volume was 530 ml(30-2 600 ml). There were 117 cases of pleural effusion after operation, including 3 patients needing invasive therapy. Ascites occurred in 23 patients, 6 of whom needed invasive therapy. Biliary leakage was observed in 30 patients. Eight patients occurred hepatic cutting surface hemorrhage, 6 of whom received blood transfusion, and 4 of whom underwent laparotomy to stop bleeding. Three patients had pulmonary infection after surgery and 3 patients appeared biliary obstruction. Deep vein thrombosis took place in 2 patients and portal vein thrombosis was observed in 4 patients. No postoperative liver failure and death ever happened in our study group. Conclusion: Three-dimensional visualization technique can optimize the treatment strategy of patients with liver malignant tumor, improve surgical safety.

Abstract
The aim of this study was to evaluate the clinical and radiographic outcomes of upper thoracic (UT) versus lower thoracic (LT) upper instrumented vertebrae (UIV) for adult scoliosis by meta-analysis. We conducted a literature search in three databases to retrieve related studies up to March 15, 2017. The preliminary screened studies were assessed by two reviewers according to the selection criteria. All analyses were carried out using the statistical software package R version 2.31. Odds ratios (OR) with 95% confidence intervals (CI) were used to describe the results. The I2 statistic and Q statistic test were used for heterogeneity assessment. Egger's test was performed to detect publication bias. To assess the effect of each study on the overall pooled OR or standardized mean difference (SMD), sensitive analysis was conducted. Ten trials published between 2007 and 2015 were eligible and included in our study. Meta-analysis revealed that the UT group was associated with more blood loss (SMD=0.4779, 95%CI=0.3349-0.6209, Z=6.55, P<0.0001) and longer operating time (SMD=0.5780, 95%CI=0.1971-0.958, Z=2.97, P=0.0029) than the LT group. However, there was no significant difference in Oswestry Disability Index, Scoliosis Research Society (SRS) function subscores, radiographic outcomes including sagittal vertical axis, lumbar lordosis, and thoracic kyphosis, length of hospital stay, and revision rates between the two groups. No evidence of publication bias was found between the two groups. Fusion from the lower thoracic spine (below T10) has as advantages a shorter operation time and less blood loss than upper thoracic spine (above T10) in posterior long-segment fixation for degenerative lumbar scoliosis.

Abstract
AIM To evaluate the relationship between the imaging features of combined hepatocellular-cholangiocarcinoma (CHC) on contrast-enhanced ultrasound (CEUS) and clinicopathological findings. MATERIALS AND METHODS From August 2004 to August 2016, 40 patients (29 males, 11 females; mean age 52.8±11.2 years) with histopathologically proven CHC were investigated. The CEUS imaging features and clinicopathological findings of CHC were analysed and compared retrospectively. RESULTS On CEUS, peripheral irregular rim-like enhancement, diffuse heterogeneous enhancement, and diffuse homogeneous enhancement was illustrated in 13 (32.5%), 21 (52.5%), and six (15%) lesions, respectively. Histopathological findings showed hepatocellular carcinoma (HCC) predominance and cholangiocarcinoma (CC) predominance throughout the tumour were illustrated in 21 (52.5%) and 19 (47.5%) cases, respectively. HCC-predominant CHCs displayed diffuse heterogeneous enhancement more frequently than peripheral irregular rim-like enhancement (p=0.005), whereas CC-predominant CHCs displayed peripheral irregular rim-like enhancement more frequently than diffuse heterogeneous enhancement and homogeneous enhancement (p=0.005 and p=0.01, respectively). CHCs >5 cm displayed diffuse heterogeneous enhancement more frequently than diffuse homogeneous enhancement, whereas CHCs ≤5 cm displayed diffuse homogeneous enhancement more frequently than diffuse heterogeneous enhancement (p=0.004). CONCLUSION The enhancement pattern of CHC on CEUS depended on the relative proportions of the HCC and CC components and showed size-dependent characteristics.

Abstract
BACKGROUND Smoking rates are higher among adolescents in South Korea than among those in other Asian countries. Researchers have reported associations between the presence of licensed tobacco retailers and adolescent smoking rates. However, few researchers have examined the factors that influence adolescent smoking including those that are intrapersonal, interpersonal or related to the tobacco retailers' environment. AIM The purpose of this study was to describe factors related to the students, the licensed tobacco retailers and the schools and how those factors are associated with adolescent smoking outcomes such as tobacco marketing receptivity, lifetime smoking and current smoking. METHODS The survey data were gathered from 740 South Korean adolescents, and geographic data for 3488 licensed tobacco retailers were also used. Geographic Information Systems and multilevel modeling were used to describe the variables and determine the factors associated with smoking outcomes in the sample. RESULTS The factors that influenced receptivity to tobacco marketing included the presence of peers who smoke and the frequencies of licensed tobacco retailers passed on the way to school. The factors that influenced lifetime smoking included gender, perceived economic status, weekly income, the presence of siblings or peers who smoke and frequencies of licensed tobacco retailers passed on the way to school. The factors that influenced current smoking included gender, weekly income, and the presence of siblings or peers who smoke. CONCLUSIONS These factors will guide adolescent tobacco prevention programs and policies. IMPLICATIONS FOR NURSING PRACTICE AND HEALTH POLICY The study's implications for nursing practice and health policy are that school nurses and public health nurses need to be encouraged to use retailer-related factors in adolescent smoking-prevention programs. There is also a need for zoning and licensing regulations to restrict licensed tobacco retailers in areas that adolescents frequent, including schools.

Abstract
Objective: To investigate the prevalence and clinical characteristics of peripheral blood eosinophilia (EOS) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods: From July 2014 to June 2016, AECOPD patients in the Department of Respiratory Medicine of Affiliated Hospital of Chengdu University, were retrospectively stratified into two groups according to two standards of eosinophilic exacerbations (the peripheral blood eosinophil count ≥2% or ≥3% on admission). Demography, clinical symptoms, laboratory results, length of stay, total hospitalization expenses, and defined daily expenses were compared between groups. Results: A total of 559 cases with AECOPD were finally recorded, the prevalence of eosinophilia was 43.1% (241 cases by EOS≥2%) and 27.2% (152 cases by EOS≥3%), respectively. According to either standard, there were no significant differences in sexes, age, course of disease (P>0.05), and there were no significant differences in global initiative for chronic obstructive lung disease (GOLD) grades, parameters of pulmonary function, modified british medical research council (mMRC) scores, rate of antibiotic use, systemic glucocorticoids administration, and average daily expenses (P>0.05). According to 2% standard, leucocytes, neutrophils, monocytes, hs-CRP were lower than non-eosinophilic patients [(5.9±2.0)×10(9)/L vs (8.2±4.0)×10(9)/L, (3.9±1.6)×10(9)/L vs (6.5±3.8)×10(9)/L, (0.446±0.169)×10(9)/L vs (0.501±0.276)×10(9)/L, (25.8±35.9) vs (46.2±55.6) mg/L, all P<0.01]; basophils, lymphocytes were higher than non-eosinophilic patients [(0.043±0.025)×10(9)/L vs (0.029±0.021) ×10(9)/L, (1.3±0.6) ×10(9)/L vs (1.1±0.6) ×10(9)/L, both P<0.01]; length of stay, total hospital expense were shorter (or lower) than non-eosinophilic patients [(10.6±5.0) vs (11.6±5.8) d, (11 851±7 491) vs (14 254±10 751) RMB, both P<0.05]. According to 3% standard, leucocytes, neutrophils, monocytes, hs-CRP were lower than non-eosinophilic patients (all P<0.05), and basophil were higher than non-eosinophilic patients (P<0.01), but no significant differences were observed in lymphocytes, length of stay and total hospital expense (all P>0.05). Conclusion: Eosinophilia is of relative high prevalence in AECOPD patients, and basophil in eosinophilic patients is higher than non-eosinophilic patients.

Abstract
Maintaining teeth in their corrected positions following orthodontic treatment can be extremely challenging. Teeth have a tendency to move back towards the original malocclusion as a result of periodontal, gingival, occlusal and growth related factors. However, tooth movement can also occur as a result of normal age changes. Because orthodontics is unable to predict which patients are at risk of relapse, those which will remain stable and the extent of relapse that will occur in the long-term, clinicians need to treat all patients as if they have a high potential to relapse. To reduce this risk, long term retention is advocated. This can be a significant commitment for patients, and so retention and the potential for relapse must form a key part of the informed consent process prior to orthodontic treatment. It is vital that patients are made fully aware of their responsibilities in committing to wear retainers as prescribed in order to reduce the chance of relapse. If patients are unable or unwilling to comply as prescribed, they must be prepared to accept that there will be tooth positional changes following treatment. There is currently insufficient high quality evidence regarding the best type of retention or retention regimen, and so each clinician's approach will be affected by their personal, clinical experience and expertise, and guided by their patients' expectations and circumstances.

Abstract
To explore the therapeutic effect of curcumin (Cur) and soybean oligosaccharides (SBOS) on ulcerative colitis (UC) through testing the intestinal flora and ulcerative colitis (UC). 80 male SD rats were selected divided into four groups with 20 rats in each group: normal group, sulfasalazine (SASP) group, model group and group of curcumin plus soy oligosaccharide. All animals were treated for 4 weeks. In the fifth week rats were decapitated. Macroscopic damage scores of colonic mucosa were calculated. A 4mL blood sample was taken to detect the contents of serum tumor necrosis factor -α (TNF-α) and interleukin 8 (IL-8) by the double antibody sandwich ABC-ELISA method (enzyme-linked immunosorbent assay). Colonic tissues with the most obvious lesions were obtained using a surgical scissor. A routine hematoxylin-eosin (HE) staining method was used to stain pathological specimens and images of staining results were obtained. Histological injury scores of colonic mucosa were calculated. Ulcerative colitis model rats had the highest macroscopic damage scores and histological injury scores of colonic mucosa. After treatment the contents of TNF-α and IL-8 decreased significantly in the group of curcumin plus soy oligosaccharide compared with the model group with statistical significance (P <0.01) while the contents were close to those in the SASP group. There was no statistical significance (P> 0.05). The treatment could decrease TNF-α and IL- 8 expression and reduce colonic mucosa inflammation and tissue damage.

[PMID: 28746466 PMCID: PMC5520219 DOI: 10.1590/1414-431x20175891] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2017] [Accepted: 05/04/2017] [Indexed: 01/24/2023]
Abstract
This study aimed to investigate the function and mechanism of microRNA-143 (miR-143) in the occurrence and development of breast cancer (BC). A total of 30 BC tissues, 30 corresponding noncancerous tissues, and 10 normal control (NC) breast tissues were obtained to detect the levels of miR-143, extracellular signal-regulated kinase 5 (ERK5) and mitogen-activated protein 3 kinase 7 (MAP3K7) using RT-qPCR, western blotting or immunohistochemistry. The correlation of miR-143 with ERK5 or MAP3K7 was evaluated using Pearson correlation analysis. MCF-7 cells were transiently transfected with miR-143 mimic, miR-143 inhibitor, miR-143 mimic/inhibitor + si-ERK5, si-MAP3K7 or si-cyclin D1. Then, cell growth was evaluated by MTT assay and the expressions of phospho-ERK5 (p-ERK5), ERK5, p-MAP3K7, MAP3K7 and cyclin D1 were detected by western blotting. Results showed that, compared with noncancerous tissues or NC breast tissues, miR-143 level was decreased, while p-ERK5, ERK5, p-MAP3K7 and MAP3K7 expressions were increased in BC tissues (all P<0.01). The miR-143 level was negatively correlated with the mRNA level of ERK5 or MAP3K7 (r=-4.231 or r=-4.280, P<0.01). In addition, up-regulated miR-143 significantly decreased the expressions of p-ERK5, ERK5, p-MAP3K7, MAP3K7 and cyclin D1 (all P<0.01), as well as cell viability in MCF-7 cells (all P<0.05) while the effect of down-regulated miR-143 was the opposite. In conclusion, both ERK5 and MAP3K7 may be the target genes of miR-143. Increased expression of miR-143 can inhibit cell growth, which may be associated with ERK5 and MAP3K7 expressions in BC.

Abstract
Rheumatoid arthritis (RA) is a chronic immune inflammatory disease mediated by the influx of immune cells into the synovial joint space. As Tanshinone IIA (TIIA) has potent anti-oxidant and anti-inflammatory activities, we used the adjuvant-induced arthritis (AA) murine model of RA to investigate the impact of TIIA on RA and immune cell activation. The anti-arthritic activity of TIIA was investigated in an adjuvant-induced arthritis model of RA in mice. Myeloperoxidase and neutrophil elastase expression levels were assessed in ankle joints by immunohistochemistry analysis. Immune cell infiltration was evaluated in air pouch experiments. Proinflammatory cytokines expression levels were determined by quantitative real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assays. Neutrophil extracellular traps (NETs) were assessed by immunostaining and confocal microscopy. Treatment with TIIA alleviated cartilage erosion and neutrophil infiltration in the ankle joints of AA mice and reduced proinflammatory cytokine expression levels in sera. TIIA suppressed interleukin-6 and tumour necrosis factor-α expression and release in neutrophils and promoted neutrophil apoptosis. TIIA also inhibited the NET formation of neutrophils. Our findings demonstrated that TIIA can ameliorate RA effectively by targeting neutrophils, indicating that TIIA may act as a potential therapeutic for RA.

Abstract
Total gastric necrosis is a rare disease and easy to misdiagnose. Here we report a rare case of total gastric necrosis. The patient, an 89-year-old male, had epigastric pain for 5 days. He was transferred to our hospital because of intraperitoneal hemorrhage and hypovolemic shock. We performed an emergency laparotomy. During the surgery, we found a total of 3500ml unclotted blood in the abdomen, splenic infarction and gastric necrosis. Total gastrectomy with Roux-en-Y esophagojejunostromy and splenectomy was performed. However, the patient died on the second day after the surgery. This case suggests that surgical treatment should be performed as early as possible when ischemia of abdominal organs is suspected.

MicroRNA-92a-3p regulates the expression of cartilage-specific genes by directly targeting histone deacetylase 2 in chondrogenesis and degradation. Osteoarthritis Cartilage 2017; 25:521-532. [PMID: 27884646 DOI: 10.1016/j.joca.2016.11.006] [Citation(s) in RCA: 80] [Impact Index Per Article: 11.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2016] [Revised: 11/08/2016] [Accepted: 11/12/2016] [Indexed: 02/02/2023]
Abstract
OBJECTIVE Increased activity of histone deacetylase 2 (HDAC2) has been found in patients with osteoarthritis (OA) and cartilage matrix degradation and has been shown to mediate the repression of cartilage-specific gene expression in human chondrocytes. We aimed to determine whether microRNA-92a-3p (miR-92a-3p) regulates cartilage-specific gene expression via targeted HDAC2 in chondrogenesis and degradation. METHODS miR-92a-3p expression was assessed in vitro in a human mesenchymal stem cells (hMSCs) model of chondrogenesis and in normal and OA primary human chondrocytes (PHCs), and in normal and OA human cartilage by in situ hybridization. hMSCs and PHCs were transfected with miR-92a-3p or its antisense inhibitor (anti-miR-92a-3p), respectively. PHCs were transfected with miR-92a-3p or anti-miR-92a-3p for 24 h before chromatin immunoprecipitation (ChIP) assay was performed with anti-ac-H3 antibody. Direct interaction between miR-92a-3p and its putative binding site in the 3'-untranslated region (3'-UTR) of HDAC2 mRNA was confirmed by luciferase reporter assay. RESULTS miR-92a-3p expression was elevated in chondrogenic and hypertrophic hMSC, while reduced in OA cartilage compared with normal cartilage. The overexpression of miR-92a-3p suppressed the activity of a reporter construct containing the 3'-UTR and inhibited HDAC2 expression in both hMSCs and PHCs, while treatment with anti-miR-92a-3p enhanced HDAC2 expression. ChIP assays showed that miR-92a-3p enhances H3 acetylation on aggrecan (ACAN), cartilage oligomeric protein (COMP) and Col2a1 promoter, and also promotes relative cartilage matrix expression. CONCLUSION Our results suggest that miR-92a-3p regulates cartilage development and homeostasis, which directly targets HDAC2, indicating histone hyperacetylation plays an important role in increased expression of cartilage matrix.
