There is an obvious need to diagnose hepatocellular carcinoma using novel non-invasive and sensitive biomarkers. In this regard, the aim of this study was to evaluate and correlate both relative quantification of microRNA-7 using quantitative real time polymerase chain reaction and quantitative analysis of selenoprotein P using enzyme-linked immunosorbent assay in sera of hepatocellular carcinoma patients, chronic liver disease patients, as well as normal healthy subjects in order to establish a new diagnostic biomarker with a valid non-invasive technique. In addition, this study aimed to investigate whether changes in selenium supply affect microRNA-7 expression and selenoprotein P levels in human hepatocarcinoma cell line (HepG2). The results showed a highly significant decrease in serum microRNA-7 relative quantification values and selenoprotein P levels in malignant group in comparison with benign and control groups. The best cutoff for serum microRNA-7 and selenoprotein P to discriminate hepatocellular carcinoma group from benign and control groups was 0.06 and 4.30 mg/L, respectively. Furthermore, this study showed that changes in selenium supply to HepG2 cell line can alter the microRNA-7 profile and are paralleled by changes in the concentration of its target protein (selenoprotein P). Hence, serum microRNA-7 and selenoprotein P appear to be potential non-invasive diagnostic markers for hepatocellular carcinoma. Moreover, the results suggest that selenium could be used as an anticancer therapy for hepatocellular carcinoma by affecting both microRNA-7 and selenoprotein P.

AbstractBackground and objectives:Chronic nonspecific pharyngitis is a chronic inflammation of the pharynx. It is found worldwide, and treatment is difficult. The underlying aetiopathogenesis is still controversial. The aim of this study was to investigate Helicobacter pylori seroprevalence in chronic nonspecific pharyngitis patients without other possible causative factors for chronic pharyngeal irritation and without H pylori gastric mucosal infection.Materials and methods:Forty-one patients with symptoms of chronic nonspecific pharyngitis and 30 healthy control subjects were enrolled in this prospective, controlled, clinical study. In both study and control groups, selected patients were shown to have gastric mucosa uninfected by H pylori, as demonstrated by the 14C-urea breath test. Comprehensive otorhinolaryngological examination did not elicit any factor contributing to the chronic pharyngeal complaint. Serum H pylori immunoglobulin G antibody titres were assayed using serum enzyme-linked immunosorbent assay. The difference between the study and control groups was analysed by the chi-square test (the likelihood ratio was used).Results:Thirty-two of the 41 patients (78 per cent) and 14 of the 30 control subjects (46.7 per cent) were found to be H pylori positive. Patients with chronic nonspecific pharyngitis were found to have a significantly higher rate of H pylori seropositivity than the control group (p = 0.016).Conclusion:These data may be important in developing future treatment strategies for chronic nonspecific pharyngitis.

Background This study evaluated changes in interleukin (IL)-27 levels in patients with acute coronary syndrome (ACS) and their influence on Th1, Th2, and Th17 cells. Methods Serum levels of IL-27, IL-4, IL-17, and interferon (IFN)-γ in healthy subjects as well as patients with ACS, including stable angina pectoris (SA), unstable angina pectoris (UA), and acute myocardial infarction (AMI), were determined using an enzyme-linked immunosorbent assay. The proportions of Th1, Th2, and Th17 cells among peripheral blood mononuclear cells (PBMCs), were measured using flow cytometry, after incubation with phorbol myristate acetate (PMA) for 4 h. The proportions of Th1 and Th17 cells among PBMCs in AMI and UA were detected after stimulation with IL-27 or PMA + IL-27 for 4, 8, and 12 h. Results Serum levels of IL-27 in patients with AMI and UA were significantly lower than those in SA and control groups, while serum levels of IL-17 and IFN-γ in AMI and UA groups were dramatically increased compared to those in SA and healthy control groups. However, there were no statistically significant differences in serum IL-4. The proportions of Th1 and Th17 cells among PBMCs were statistically significantly higher in the AMI and UA groups than those in the SA and control groups, while there was no statistically significant difference in the proportion of Th2 cells among different groups. For patients with AMI and UA, the effect of co-stimulation of PBMCs with PMA and IL-27 was not significantly different from that of PMA single stimulation, while PMA + IL-27 co-stimulation lowered the Th17 cell proportion significantly compared to PMA single stimulation. Discussion Compared to SA patients and healthy controls, patients with ACS (AMI + UA) had lower serum levels of IL-27 and higher proportions of PBMC Th1 and Th17 cells, which could be attributed to the inhibitory effects of IL-27 on the proliferation of Th17 cells. These results indicated that IL-27 could be a novel therapeutic target in ACS patients.

Abstract Introduction:Electroconvulsive therapy (ECT) is the oldest procedure among the early biological treatments introduced in psychiatry. However, the most debated and treatment-limiting adverse effect of ECT is amnesia. Therefore, due to the restriction of the use of drugs to manage amnesia in patients undergoing ECT, the present study investigated the effect of reflexology on amnesia. Methods:In this randomized controlled trial, 68 patients who met the inclusion criteria were randomly allocated to intervention and control groups. The intervention group received foot reflexology with olive oil 20 minutes a day for 3 days, while the control group was given a gentle foot rub with olive oil 20 minutes a day for 3 days. The amnesia rate of all patients was measured by the Galveston Orientation and Amnesia Test (GOAT) 30 minutes after the end of ECT. The data were analyzed using SPSS software version 11.5 and t-test, chi-squared test, and repeated measures ANOVA. Results:The results showed that reflexology significantly increased recalling scores in the intervention group compared to the control group. Foot reflexology seems to be effective in managing amnesia in patients after ECT. Conclusion:Foot reflexology, as a relatively simple, inexpensive, and non-invasive technique with few side effects, can be used to manage amnesia in patients after ECT.

Abstract. Background: We investigated the association of the 5A/6A polymorphism in the promoter region at -1612 of the matrix metalloproteinase-3 gene (MMP-3-1612) and deep venous thrombosis (DVT). Patients, materials and methods: The distribution of the MMP-3 (-1612 5A/6A) polymorphism in the case and control groups was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Serum MMP-3 level of two groups was detected using enzyme-linked immunosorbent assay (ELISA). HepG2 cells containing MMP-3-1612 recombinant plasmid were cultured in vitro and the MMP-3 level was defined by luminescence intensity of luciferase. A DVT rat model was built. Serum MMP-3 level in the rats’ wounded vein at different time points was detected by ELISA and recorded for investigation of the association between MMP-3 and DVT. Statistical data analysis was conducted with SPSS18.0. Results: On the basis of the observation of MMP-3-1612 genotype frequency and allele frequency in the case and control groups, we identified significantly higher MMP-3-1612 5A allele frequency and higher serum MMP-3 level in the case group than in the control group (both P < 0.05). According to in vitro luciferase measurements, the 5A allele had higher transcriptional activity than the 6A allele. As observed in the rat model, serum MMP-3 level increased with time passing and thrombosis formation after modelling. Conclusions: The MMP-3-1612 5A/6A polymorphism may effect serum MMP-3 level and over-expression of serum MMP-3 level may be a risk factor for DVT formation.

Abstract Objectives In this study, the seroprevalence of anti-Toxoplasma gondii (T. gondii) specific antibodies in patients undergoing hemodialysis compared to the control group were evaluated. In this case–control study, 200 hemodialysis patients (HDP) and 100 healthy controls were participated. The specific antibodies (IgG/IgM) in both groups were tested using enzyme-linked immunosorbent assay (ELISA) method. A structured questionnaire containing some demographic information was completed for each person in case and control groups. Results The overall seroprevalence of T. gondii infection was 49.5% (99/200) and 23.0% (23/100) in the case and control groups, respectively. There was a significant association between seroprevalence of T. gondii infection and contact with cats (P < 0.001), consumption of raw/undercooked meat (P = 0.01), and source of drinking water (P = 0.001) in the hemodialysis patients. Also, in the control subjects, there were a significant association between consumption of raw/undercooked meat (P = 0.04) and source of drinking water (P = 0.001) with T. gondii infection. The findings showed a high seroprevalence of T. gondii infection in HDP compared with healthy controls; thus, we recommend the regular screening programs for T. gondii infection in this susceptible group.

Objective To explore the relationship between the omentin-1 gene rs2274907 A>T polymorphism and colorectal cancer (CRC) in the Chinese Han population. Methods rs2274907 A>T was assessed by PCR–restriction fragment length polymorphism analysis. Plasma omentin-1 expression from 358 patients with CRC and 286 healthy controls was analyzed by enzyme-linked immunosorbent assay. CRC and control groups were divided into subgroups according to the body mass index (BMI) threshold of 25 kg/m2. Results No significant differences were observed between CRC and control groups in terms of genotype or allele frequencies of rs2274907 A>T. Compared with individuals with BMI <25 kg/m2 and the rs2274907 TT genotype, those with AA+AT genotypes and BMI ≥25 kg/m2 had a 3.027-fold increased risk of CRC. A significant tendency toward a higher stage of colorectal adenocarcinomas and depth of invasion was observed in individuals with the rs2274907 AA genotype compared with other genotypes. Conclusions The omentin-1 gene rs2274907 A>T polymorphism does not seem to play a critical role in the development of CRC in the Chinese Han population, but an interaction between the rs2274907 A allele and BMI may increase the CRC risk. The rs2274907 AA genotype is a potential biomarker for CRC stage progression.

Stereotactic body radiotherapy (SBRT) is an emerging ablative modality for hepatocellular carcinoma (HCC). Most patients with HCC have advanced disease at the time of diagnosis, and therefore, are not candidates for definitive-intent therapies such as resection or transplantation. For this reason, various alternative local and regional therapies have been used to prevent disease progression, palliate symptoms, and delay liver failure. Stereotactic body radiation therapy is a non-invasive technique of delivering ablative doses of radiation to tumors while sparing normal or non-tumor hepatic tissue. Incorporation of SBRT in multidisciplinary HCC management is gradual, initially applied when other liver-directed therapies have failed or are contraindicated, and tried in combination with other locoregional or systemic therapies for more unfavorable conditions by more experienced teams. In order to improve SBRT therapeutic ratio, there has been much interest in augmenting the effect of radiation on tumors by combining it with chemotherapy, molecularly targeted therapeutics, nanoparticles, and immunotherapy. This review aims to synthesize available evidence to evaluate the clinical feasibility and efficacy of SBRT for HCC, and to explore novel radio-potentiation concepts by combining SBRT with novel therapeutics. It is expected that those approaches would result in improved therapeutic outcomes, even though many questions remain with regard to the optimal way to assemble treatments. Further trials are needed to evaluate and consolidate these promising therapies for HCC.

Aim To evaluate the safety and efficacy of the administration of radiofrequency ablation (RFA) and stereotactic body radiotherapy (SBRT) in the short term to the same patients in Barcelona Clinical Liver Cancer (BCLC) stages 0–B1. Methods From April 2014 to June 2019, we retrospectively reviewed BCLC stage 0–B1 patients with fresh hepatocellular carcinoma (HCC) lesions that were repeatedly treated by RFA (control group, n = 72), and by RFA and subsequent SBRT (case group, n = 26). Propensity score matching (PSM) was performed to reduce the selection bias between two groups. Recurrence, survival, Child–Pugh scores and short-term side effects (fever, bleeding, skin change, abdominal pain and fatigue) were recorded and analyzed. Results After PSM, 21 patients remained in each group. Seventeen and 20 patients in the case and control groups experienced recurrence. For these patients, the median times to progression and follow-up were 10.7 and 35.8 months, respectively. After PSM, the 1-year progression-free survival rate in case and control groups were 66.7% and 52.4%, respectively (P = 0.313). The inter-group overall survival (OS) was comparable (3 and 5-year OS rates in case groups were 87.3% and 74.8%, while rates in control groups were 73.7% and 46.3%, respectively; P = 0.090). The short-term side effects were mild, and the incidence showed no inter-group difference. The 1-year rates of the Child–Pugh score deterioration of ≥2 in case and control groups were 23.8% and 33.3% (P > 0.05), respectively. Conclusion The short-term administration of RFA and SBRT to the same BCLC stage 0–B1 patients may be feasible and effective because of their good prognosis and safety.

BackgroundMicrovascular invasion (MVI) is a significant predictive factor for early recurrence, metastasis, and poor prognosis of hepatocellular carcinoma. The aim of the present study is to identify preoperative factors for predicting MVI, in addition to develop and validate non-invasive nomogram for predicting MVI.MethodsA total of 381 patients with resected HCC were enrolled and divided into a training cohort (n = 267) and a validation cohort (n = 114). Serum VEGF-A level was examined by enzyme-linked immunosorbent assay (ELISA). Risk factors for MVI were assessed based on univariate and multivariate analyses in the training cohort. A nomogram incorporating independent risk predictors was established and validated.ResultThe serum VEGF-A levels in the MVI positive group (n = 198) and MVI negative group (n = 183) were 215.25 ± 105.68 pg/ml and 86.52 ± 62.45 pg/ml, respectively (P &lt;0.05). Serum VEGF-A concentration ≥138.30 pg/ml was an independent risk factor of MVI (OR: 33.088; 95%CI: 12.871–85.057; P &lt;0.001). Higher serum concentrations of AFP and VEGF-A, lower lymphocyte count, peritumoral enhancement, irregular tumor shape, and intratumoral artery were identified as significant predictors for MVI. The nomogram indicated excellent predictive performance with an AUROC of 0.948 (95% CI: 0.923–0.973) and 0.881 (95% CI: 0.820–0.942) in the training and validation cohorts, respectively. The nomogram showed a good model fit and calibration.ConclusionsHigher serum concentrations of AFP and VEGF-A, lower lymphocyte count, peritumoral enhancement, irregular tumor shape, and intratumoral artery are promising markers for MVI prediction in HCC. A reliable non-invasive nomogram which incorporated blood biomarkers and imaging risk factors was established and validated. The nomogram achieved desirable effectiveness in preoperatively predicting MVI in HCC patients.

Background: Considering the importance of treatment of sour nipples in breastfeeding mothers, the aim of this study was to evaluate the effect of dexpanthenol creams on the treatment of traumatic nipples. Materials and Methods: This study was a double-blinded, randomized, control trial, in which 82 postpartum mothers with nipple injuries who had attended health centers and Children’s Hospital of Sanandaj, Iran, participated. The participants were randomly divided into two groups of dexpanthenol and control. Nipple pain and trauma was measured using Storr and Champion scale. Analysis was done through chi-square and ANOVA tests using SPSS software version 13.0. P value less than 0.05 was considered significant. Results: The results of this study demonstrated that the mean score of pain and trauma in third, seventh, and fourteenth days of study in intervention group was decreased. In addition, there was significant differences in pain and trauma scores between dexpanthenol and control groups. Conclusion: Dexpanthenol is advised as an effective, simple, and non-invasive technique with no side effects for the treatment of nipple fissures and pain.
