Background: We aimed to detect IL-17, MMP-9 and CD23 in serum of patients with colorectal cancer to provide some proper references for diagnosis and treatment of this disease. Methods: Overall, 287 patients with colorectal cancer were collected in the Digestive Surgery Department of Chinese PLA General Hospital, Beijing, China from January 2017 to November 2018 and were used as the study group, meanwhile, 200 people who took physical examination in the same period were used as the control group. They were retrospectively analyzed. The concentrations of IL-17, MMP-9 and CD23 in serum were detected by ELISA 10 d before and after treatment and 30 d after treatment. The relationship between IL-17, MMP-9 and CD23 concentration and clinicopathology was analyzed. Results: The concentrations of CD23, IL-17 and MMP-9 in peripheral blood of the patients in the study group were significantly higher than those in the control group (P<0.001). IL-17, MMP-9 and CD23 were negatively correlated with treatment time and pathological features in the study group (P<0.001). Conclusion: The concentrations of IL-17, MMP-9 and CD23 obviously increased in peripheral blood of patients with colorectal cancer, the three were negatively correlated with treatment time and were significantly correlated with TNM staging and differentiation degree of colorectal cancer. It is expected to estimate the illness.

Background and objectives: T regulatory lymphocytes (Treg) are one of the subsets of T-lymphocytes involved in the interaction of neoplastic tumors and the host immune system, and they may impair the immune reaction against cancer. It has been shown that Treg are increased in the peripheral blood of patients with various cancers. In colorectal cancer, the prognostic role of Treg remains controversial. Colorectal cancer is a heterogenous disease, with many variations stemming from its primary tumor location. The aim of this study is to analyse the relationship between the amount of Treg in the peripheral blood of patients with left-sided colorectal cancer in various stages of disease and long-term survival. Materials and Methods: A prospective analysis of 94 patients with left-sided colorectal cancer and a group of 21 healthy volunteers was carried out. Treg levels in peripheral blood were analysed using flow cytometry. Results: There was a statistically significant difference between the amount of Treg in the Ist and IInd TNM stages (p = 0.047). The number of Treg in the entire study group was significantly lower than in the control group (p = 0.008) and between patients in stages II and III and the control group (p = 0.003 and p = 0.018). The group of pT3+pT4 patients also had significantly lower Treg counts in their peripheral blood than the control group (p = 0.005). In the entire study group, the level of Treg cells in the peripheral blood had no influence on survival. The analysis of the TNM stage subgroups also showed no difference in survival between patients with “low” and “high” Treg counts. Conclusion: The absolute number of Treg in the peripheral blood of patients with left-sided colorectal cancer was significantly decreased in comparison to healthy controls, especially for patients with stage II+III disease. Treg presence in the peripheral blood had no impact on survival.

Objective: This study aims to investigate the expression and clinical significance of Th17 cells and related factors in peripheral blood of patients with Autoimmune Hepatitis (AIH). Methods: A retrospective selection of 100 patients with AIH were included as a study group, and 100 healthy volunteers in the outpatient clinic were selected as the control group. The levels of IL- 17, IL-6, IL-21 and TNF-α in peripheral blood of all subjects were detected by enzyme-linked immunosorbent assay and the frequency of Th17 cells and Treg cells was detected by flow cytometry. Results: Results showed that the study group had higher levels of serum total bilirubin (TBil), alkaline phosphatase (ALP), γ -glutamyltranspeptidase (γ-GT), immunoglobulin G (IgG), immunoglobulin M (IgM), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) than the control group, as well as higher levels of IL-17, IL-6, IL-21 and TNF-α in serum. The frequency of Th17 cells in peripheral blood was higher in the study group, while the frequency of Treg cells was lower. Also, serum IL-17, TNF-α levels and Th17 cells frequency were positively correlated with ALT and AST, whereas Treg cells frequency were negatively correlated with ALT and AST levels. Conclusion: Our finding demonstrates that Th17 cell frequency and their related factors IL-17 and TNF-α, are associated with liver damage, which might be used to monitor AIH disease severity.

Background/aims Workers engaged in vehicle spray painting are at a risk of developing respiratory problems because of the solvents in the spray paints. Changes in respiratory functions and functional capacities caused by spray painting can be improved with respiratory exercises. The aim of this study was to examine the effects of respiratory exercises on the respiratory functions, functional capacity and quality of life in vehicle spray painters. Methods A total of 70 volunteers with similar characteristics participated in the study. The groups were divided into two groups randomly (35 study group, 35 control group). Respiratory functions (value of forced expiratory volume percentage in 1 second [FEV1]), forced vital capacity percentage [FVC], FEV1/FVC percentage, peak expiratory flow percentage [PEF (%)] and maximum voluntary ventilation percentage [MVV (%)]), functional capacity (6-Minute Walk Test) and quality of life (Short Form Health Survey [SF-36]) were evaluated. The study group undertook supervised breathing exercises 3 days a week for 6 weeks. The same exercises were given to the control group as a home programme. Home programmes were followed up by telephone calls. Evaluations were performed again after 6 weeks. Results In the study group, FEV1 (%) increased more than in the control group (P<0.05). The increase in PEF (%) was similar in both groups (P>0.05). In the study group, FEV1/FVC (%) and MVV (%) were significantly different before and after the intervention (P<0.05), but there was no difference in the control group (P>0.05). There was a greater increase in the study group than in the control group (P<0.05). 6-Minute Walk Test distance (m) before and after the intervention in both groups were similar (P>0.05). Before and after the intervention, a significant difference was found in the vitality and the social function domains of the SF-36 in the study group. In the comparisons of groups, a significant difference was found in the study group in the role-emotional, social function and bodily pain domains of the SF-36 after the intervention (P<0.05). Conclusions Breathing exercises can be recommended for vehicle spray painters to avoid an increase in respiratory resistance and to improve their quality of life.

Research background. Falling is one of the most important problems in the elderly’s mobility disorder, which is most often affected by the loss of balance. It is known that Pilates exercises could help to increase the deep muscle strength, improve posture and proprioception, which affects the improvement of the balance. Objective – to evaluate the effects of Pilates exercises on the elderly’s static and dynamic balance. Methodology. The study population consisted of 20 volunteers, men and women, who were divided into Pilates exercises (n = 10, age 65.1 ± 2.6) and control (n = 10, age 68.6 ± 4.9) groups. The study group participated in Pilates classes 2 times per week for six weeks (session duration 60 minutes). The control group did not participate in any physical activity, but they were physically active as usually in their daily life. The main outcome measures were assessed before and after the intervention. The static balance was assessed by measuring posturographic parameters using the force platform, dynamic balance was measured with the Timed up and Go Test (TUG) and the Four Square Step Test (FSST). Results. The results showed signifcant improvement in static balance of the experimental group after the Pilates exercises during standing tests when the feet were apart, eyes opened and closed and when the feet together with eyes opened, and when the foot was in front of the other foot. The results of the control group did not differ during both tests. The results of both groups did not differ in the static balance tests before and after the study, but after the Pilates exercises, the results of the Pilates group signifcantly differed from the control group test results when the feet were in shoulder line with open eyes. The results of the dynamic balance after Pilates exercises signifcantly improved in both tests in the study group. Before the study, there were not statistically signifcant differences in the dynamic balance results between the groups. Conclusions. Six-week Pilates exercises had a positive effect on the elderly’s static and dynamic balance.Keywords: Pilates training, static balance, dynamic balance.

Vanilloid Receptors

Abstract Background: Endocannabinoids take part in physiology of neural and immune system. Last data showed that these compounds and their receptors play an important role in proliferation and apoptosis of different neoplastic cells. Cannabinoids were shown to increase the apoptosis in human neoplastic cells through a number of mechanisms including vanilloid receptors (Sanchez et al. 1998, Maccarone et al. 2000). The vanilloid receptor family of cation channels includes the capsaicin-sensitive, proton- and heat-activated vanilloid receptor type I (TRPV1). Furthermore Saunders et al. (2006) showed that TRPV1 are expressed on normal lymphocytes in human peripheral blood. Aims: The aim of our study was the assessment of receptor TRPV1 mRNA expression in the lymphocytes B derived from patients with newly diagnosed chronic lymphocytic leukaemia. Material and methods: The study group contains newly diagnosed, untreated adult patients with B-cell chronic lymphocytic leukaemia; 11 males and 10 females, aged from 46 to 74. The patients were in A-C stage according to Binet. We used 13 samples from healthy donors as a control group. The isolation of mononuclear cells from peripheral blood was carried out with the use of density centrifugation method. The resolution of mononuclear cell population to lymphocytes B subpopulation was done with negative isolation method utilizing magnetic microballs (Dynal). Total RNA was isolated from B-lymphatic cells of which 10ng was used in each reaction. Quantitative RT-PCR was carried out with the use of Light Cycler (Roche) and respective commercial kits. The nucleotides sequence of the studied receptor and parameters of the amplification process were based on method previously described by Qiao et al (2003). We used house keeping gene hexose-6-phosphate dehydrogenase (glucose 1-dehydrogenase) (G6PDH) as a reference gene. Amplification product was sequenced by ABI PRISM (Applied Biosystem). All results are presented as a mean concentration ratio of TRPV1 to G6PDH mRNA ± standard error. Statistical analysis was performed using Shapiro-Wilk, non parametric U Mann-Whitney Tests. Results: We found that concentration ratio of studied transcript was significantly lower in the study group in comparison to the control group (0,048± 0,012 vs. 106,836± 40,215 respectively. We found no differences between the subgroups irrespectively of gender, age, stage of the disease and some prognostic factors (LDH, lymphocyte doubling time, β2-microglobulin). Conclusions: The results confirm the existence of vanilloid receptors on the lymphocytes B of healthy individuals and for the first time show presence of this type of receptors in CLL group. The lower level of TRPV1 transcripts in the group of patient may suggests their potential role in the process of leukemic transformation. Thus the effect of endocannabinoids through this receptor may be altered in CLL. However, further studies are required to elucidate the nature of relationship between this type of receptor and neoplastic development of CLL.

14512 Background: The presence of CTCs is associated with poor prognosis in patients with metastatic carcinomas. The significance of CTCs at the time of diagnosis and after therapy is not known. A prospective clinical trial is conducted to determine if monitoring CTC levels in pts diagnosed with breast and colorectal cancer identify pts at risk for recurrence. CTCs are correlated with pathological stage as follow-up is too short to assess recurrence risk. Methods: Currently 213 pts with newly diagnosed breast and 119 pts with colorectal cancer before surgery with curative intend have been enrolled as well as a control group of 120 patients in whom diagnosis of breast or colorectal cancer was excluded. Thirty ml of blood was screened for the presence of CTCs at baseline before surgery and every following year using the CellSearch™ System. Results: Presence of CTCs in 30mL of blood in breast, colorectal cancer and the control group is provided in the table . In colorectal cancer the average number of CTCs /30 mL at baseline for Dukes A, B and C was 0.2, 0.7 and 1.1 respectively, for stage 0, I, II, III breast cancer 0.3, 0.5, 0.6 and 1.8 respectively and for the control group 0.24 CTCs /30 mL. Conclusions: CTC can be detected in a substantial proportion of pts before and after definitive surgery for breast and colorectal cancer. The number of CTCs before surgery correlated with the stage of the disease. Specificity of the CellSearch™ System is being increased to improve the discrimination of patients with benign and malignant disease. Follow-up must clarify whether the presence CTCs is an identifier for the risk of recurrence. [Table: see text] No significant financial relationships to disclose.

Abstract Background miR-92b is a carcinogenic miRNA that has great potential as a biomarker for disease prognosis, diagnosis, and treatment in the clinic. It is of great significance to analyse the relationship between miR-92b and the clinicopathological characteristics of cancer patients. This paper aimed to investigate the expression levels and clinical values of miR-92b-3p in breast cancer (BC). Methods Altogether, 112 female BC patients who were treated in our hospital were included as a study group, and 108 healthy women who came to our hospital for physical examinations were included as a control group. miR-92b-3p expression in the serum of subjects in both groups was detected by fluorescence quantitative PCR (RT-PCR) to analyse the correlation of this miRNA with the patients’ pathological features and prognoses. The diagnostic value of miR-92b-3p expression for BC was analysed by plotting a receiver operating characteristic (ROC) curve. Results miR-92b-3p expression was remarkably higher in the study group (P < 0.05), and its area under the curve (AUC) for detecting BC was 0.88. The expression was correlated with the tumour size, degree of differentiation, TNM staging, and lymphatic metastasis (P < 0.05). miR-92b-3p was significantly positively correlated with the TNM staging (r = 0.40, P < 0.05), was significantly negatively correlated with the degree of differentiation of the breast cancer cells (r =  − 0.35, P < 0.05), and was significantly positively correlated with the expression of carbohydrate antigen 125 (CA125) (r = 0.39, P < 0.05). The overall survival rate (OSR) of the 99 patients who had follow-up was 73.74%. The survival status was remarkably better in the low expression group (P < 0.05). miR-92b-3p expression was remarkably higher in the death group (P < 0.05). The AUC of miR-92b-3p alone in the death and survival groups was 0.76. Conclusion miR-92b-3p expression obviously rises in the serum of BC patients and is closely related to the clinical staging, degree of differentiation, and CA125 in BC, so the detection of this miRNA is of great significance to the diagnosis and prognostic evaluation of BC. This miRNA can be used as a potential biomarker for the diagnosis and prognosis of the disease.

Zirconia Implants

Introduction: Zirconia is considered as an alternative material for the fabrication of implants. Surface roughness of the implant plays a fundamental role in the initial bone formation. The rationale of using 3D optical profilometry in this study was to evaluate the surface roughness of the zirconia implants before and after Ultraviolet (UV) photofunctionalisation. Also, Moreso 3D optical instruments have a better resolution than the mechanical ones like Atomic Force Microscopy (AFM). Aim: To analyse the surface roughness and topography of zirconia implants after photofunctionalisation using optical profilometry. Materials and Methods: This is an in-vitro study conducted over a period of six months from March 2020 to August 2020. Ten commercially machined Zirconia implants, five each in study and control group, were micro analysed at three different regions (abutment, thread and crest) by optical profilometry. Study group was surface treated by UV radiation for 48 hours. Quantitative morphometric analysis was done between two groups and p-value less than 0.05 was considered statistically significant. The statistical test applied in this study was independent t-test. Results: Scanning micrographs of the study group revealed highest density of summits contributing to increased surface area in the study group. Quantitative analysis of surface roughness showed statistically significant higher mean roughness parameter for photofunctionalised implants in abutment, crest and thread region (p<0.05). Conclusion: Photofunctionalisation is a potentially synergistic technique in producing textured zirconia implants.

Purpose: To study the combined effects of tenofovir and interferon α1b on viral load and peripheral blood regulatory T cell concentrations of chronic hepatitis B (CHB) subjects. Methods: Patients with chronic hepatitis B (86 cases) were randomly assigned to two groups: control group and study group. In control subjects, tenofovir was given orally (300 mg/kg bwt/day). In addition to tenofovir, the study group received interferon α1b injection intramuscularly at a dose of 50 μg/kg thrice a week. Liver function, serum hepatitis B viral (HBV) load, and serum levels of peripheral blood regulatory T-lymphocytes were determined. Clinical effectiveness and adverse reactions in both groups were also assessed. Results: After treatment, total effectiveness was higher in the study group (86.04 %) than in control patients (62.79 %) (p < 0.05). Serum aspartate transaminase (AST), alanine aminotransferase (ALT) and total bilirubin (TBIL) significantly decreased in the study group, relative to control, but HBV DNAnegative, HbeAg-negative and HbsAg-negative cells were markedly higher in patients in the study group (p < 0.05). Moreover, there were higher CD4+ T and CD8+ T counts, and CD4+ T/CD8+ T ratio in study subjects than in control subjects (p < 0.05). Conclusion: The combination of tenofovir with interferon α1b effectively improves liver functions in patients with CHB, reduces viral load, and exerts anti-HBV effect by regulating the levels of peripheral blood T-lymphocytes.

The objectiveis to measure the level of fatty acids in erythrocyte membranes and serum of patients with colorectal cancer.Materials and methods.The study group included 100 patients with diagnosed colorectal cancer (57 men and 43 women). The control group included 24 reasonably healthy people (14 men and 10 women) matched for age and sex, without malignant cancers or manifested pathology of the internal organs.Results.Decreased levels of saturated, monounsaturated fatty acids and increased levels of polyunsaturated fatty acids (PUFAs) in erythrocyte membranes and serum (p <0.0001–0.05) were observed. The levels of omega-3 PUFAs in colorectal cancer exceeded the levels in healthy individuals both in erythrocyte membranes and in serum; for omega-6 PUFAs only a trend was observed. At the same time, the ratio of omega-6/omega-3 PUFAs in colorectal cancer was lower than in control (p <0.0001–0.002). The state of erythrocyte membranes more significantly and for more parameters characterized differences between the groups than serum. The most discriminating parameters between patients with colorectal cancer and healthy individuals both in erythrocyte membranes and serum were the levels of C20:2;11,14 (eicosadienoic), C20:3;8,11,14 (dihomo-γ-linolenic), C20:4;5,8,11,14 (eicosatetraenoic, arachidonic), C22:5;7,10,13,16,19 (docosapentaenoic), and C22:6;4,7,10,13,16,19 (docosahexaenoic) PUFAs.
