RESUMO

With the acceleration of the population aging in China, the health problems and the demands of health services such as health check-up for rural residents should attract the attention of the whole society. The group standard entitled Health check-up guide for rural residents (T/CHAA 005-2019), was written by experienced researchers from Chinese Center for Disease Control and Prevention and other professional institutes coordinated by Chinese Health Association. The standard aims to establish a service model that takes health information collection as a means, health risk assessment, health risk intervention and information services as the core, improving the health of rural residents as the target.

RESUMO

Objective: To investigate the predictive value of epicardial adipose tissue volume (EATV) and inflammatory factors on in-stent restenosis (ISR) after percutaneous coronary implantation (PCI) in patients with coronary heart disease (CAD). Methods: A total of 407 patients with CAD who were treated with drug-eluting stents in TEDA international cardiovascular disease hospital were enrolled from November 2016 to October 2017. Levels of inflammatory cytokines such as high sensitive c-reactive protein (Hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor (TNF-α) were detected. EATV was measured preoperatively by multi-sliced CT. Patients were divided into ISR group (n=52) and N-ISR group (n=355) according to ISR occurred within 1 year after procedure. The relationship between EATV and inflammatory factors and ISR after PCI was analyzed. Results: The differences between ISR group (n=52) and N-ISR group (n=355) were statistically significant in terms of diabetes history, IL-6, TNF-α, EATV ((150±36) cm(3)vs(120±40) cm(3),P=0.001)), bifurcation lesions, stent length and Gensini score (P<0.05). Multivariate Logistic regression analysis results showed that diabetes history,bifurcation lesions, TNF-α, EATV, and Gensini score were risk factors for in-stent restenosis.The area under the ROC curve (AUC) of EATV, TNF-α, and IL-6 in patients with CAD after PCI was 0.712, 0.752 and 0.675 (95%CI 0.648-0.776, 0.686-0.819, 0.584-0.766, respectively, all P<0.001), with a sensitivity of 86.5%, 67.3% and 69.2%, a specificity of 53.8%, 74.4% and 70.1% and a cut-off value of 116.61 cm(3),138.40 µg/L and 126.4 µg/L, respectively. Conclusion: EATV, TNF-α, and IL-6 have certain predictive values for in-stent restenosis, and can be used as clinical indicators to predict in-stent restenosis.

RESUMO

Objective: To investigate the detection of thyroid nodules and related risk factors in nuclear power workers, and to provide scientific evidence for thyroid protection of nuclear power workers. Methods: In December 2018, select 295 workers of a nuclear power production enterprise and 238 administrative staff of it, and select 250 staff members of a thermal power generation enterprise 70 kilometers away from the nuclear power station to conduct thyroid ultrasound examination and questionnaire survey for single factor. Analysis and further multivariate logistic regression analysis were used to study the risk factors of thyroid nodules in the population. Results: Women and smoking history were independent risk factors for the increased incidence of thyroid nodules in the study population; three shifts work pattern was an independent risk factor for the increased prevalence of thyroid nodules in nuclear power workers (P<0.05) , and other factors such as the history of nuclear exposure had no significant correlation with thyroid nodules (P>0.05) . Conclusion: Nuclear exposure has little effect on the prevalence of thyroid nodules in nuclear power workers.

RESUMO

Objective: To compare the clinical efficacy of proximal gastrectomy with double tract reconstruction (PG-DT) and total gastrectomy with Roux-en-Y reconstruction (TG-RY) for proximal gastric cancer. Methods: The retrospective study was conducted. Clinicopathological data of 132 patients with proximal gastric cancer confirmed by pathology who underwent PG-DT (n=51) or TG-RY (n=81) by the same surgeon team in Southwest Hospital of Army Military Medical University between January 2006 and December 2016 were collected. Patients with preoperative neoadjuvant therapy, non-R0 resection and non-adenocarcinoma confirmed by pathology were excluded. Observation indicators included intraoperative (operation time and blood loss); postoperative (time to flatus, hospital stay, total complications, metastasis of lymph nodes around distal side of stomach from cases undergoing TG-RY), follow-up (long-term hemoglobin level, incidence of anemia, and survival) parameters. Survival analysis was conducted using the Kaplan-Meier method, and Log-rank test was used to compare survival difference between two groups. Results: No statistically significant differences were found between two groups in the baseline data, including age, gender, BMI, hemoglobin level before operation, postoperative TNM stage, tumor size and histological differentiation between two groups (all P>0.05). There were no significant differences between PG-DT and TG-RY in intraoperative blood loss [200 (200) ml vs. 200 (195) ml, Z=-1.860, P=0.063], time to flatus [(2.7±1.0) days vs. (2.6±1.1) days, t=0.225, P=0.823], postoperative hospital stay [10(3) days vs. 10 (4) days, Z=-0.449, P=0.654] and morbidity of perioperative complications [5.9% (3/51) vs. 8.6% (7/81), χ(2)=0.081, P=0.775]. Compared with the TG-RY group, PG-DT group had longer total operative time [294 (97) minutes vs. 255 (71) minutes, Z=-3.148, P=0.002]. The hemoglobin data of 42 patients with PG-DT and 56 patients with TG-RY were collected 1 year after operation. The incidence of anemia in PG-DT group was lower than that of TG-RY group [64.2%(27/42) vs. 82.1% (46/56), χ(2)=4.072, P=0.045], and PG-DT group had higher level of hemoglobin than TG-RY group [(114.4±16.3) g/L vs. (106.6±15.0) g/L, t=2.435, P=0.017]. There were 4 cases (4/81, 4.9%) with metastasis of lymph nodes around distal side of stomach in TG-RY group. All of these 4 tumors were T4 in depth and were more than 5 cm in diameter. The median follow-up period was 26 (1 to 110) months. One-year, 3-year and 5-year survival rates were 93.2%, 65.3% and 55.0% in PG-DT group, and 85.8%, 63.8% and 47.2% in TG-RY group, respectively without significant difference (χ(2)=0.890, P=0.345). Conclusions: Compared with TG-RY, PG-DT has the same safety and feasibility for proximal gastric cancer. Although the operative time is a little longer than TG-RY, PG-DT has advantages in improving the postoperative hemoglobin level.

RESUMO

Objective:The aim of this study is to investigate the relationship between the level of (pro) renin(P)RR in obstructive sleep apnea syndrome (OSA) patients, and the gender and disease severity of the disease.b>Method:From March 2010 to March 2018, eighty OSA patients who were treated and diagnosed in our hospital were selected as subjects. Another 20 healthy subjects were selected as the control group.Plasma soluble (pro) renin receptor ï¼»s(P)RRï¼½ levels and clinical parameters were measured in healthy subjects and OSA patients with different sex and disease severity. Result:The plasma s(P)RR concentrations were significantly higher in OSA patients than that in control group. In all patients, plasma s(P)RR concentrations increased with increasing disease levels and showed the same trend between men and women. In addition,in all patients, plasma s(P)RR concentrations were significantly positively correlated with waist-to-hip ratio, HbA1c, AHI, and oxygen desaturation index. There was a significant negative correlation between saturation (MSpO2) and minimum oxygen saturation (minSpO2) (P<0.05).In female subjects,plasma s(P)RR concentrations were significantly positively correlated with waist-to-hip ratio and AHI,but significantly negatively correlated with eGFR (P<0.05).In male subjects,plasma s(P)RR concentration was significantly positively correlated with waist-to-hip ratio,HbA1c,renin level,AHI and oxygen desaturation index, but negatively correlated with eGFR, MSpO2 and minSpO2 (P<0.05). Plasma s(P)RR concentrations were significantly reduced after treatment with nasal continuous positive airway pressure ventilator. In addition, ESS,AHI,MSpO2,minSpO2,and oxygen desaturation index were all significantly improved (P<0.05).Conclusion: Plasma s(P)RR levels in OSA patients are significantly positively correlated with the severity of the disease and can directly reflect the severity of the disease. In addition, the patient with higher waist-to-hip ratio and HbA1c, and lower eGFR can effect plasma s(P)RR levels, and may lead to OSA aggravation.

RESUMO

Objective: To investigate alteration of proteins profile in malignant transformation bronchial epithelial cells(16HBE-T) induced by hexavalent chromium[(Cr(VI))] and analyze the expression level of SET protein, then to provide some new insights for the carcinogenesis mechanism of Cr(VI). Methods: Total protein was extracted from 16HBE cells and was alkylated and desalinated before digested into peptides. The products were labeled with Tandem Mass Tag (TMT) and identified using LC-ESI-MS/MS. Results: A total of 3 517 proteins were found, expression differences greater than 1.5 or less 0.67 times were to found have 185 and 201 proteins, respectively. Gene enrichment analysis revealed that differential proteins were mainly involved in autophagy, DNA damage repair, RNA processing and other biological processes. Western blot results showed the expression level of SET was significantly increased while downregulated in histone H3K18/27 acetylation and p53 protein. Conclusion: Proteins involved in multiple biological processes altered in 16HBE-T cells and regulation mode of SET inhibiting histone H3K18/27 acetylation regulating transcriptional activity of p53 may paly an important role in Cr(VI)-association carcinogenesis.

RESUMO

Objective: To understand epidemiological characteristics of human rabies in China in 2017 and provide evidence for the development of strategy of human rabies control and prevention. Methods: The descriptive epidemiological analysis was conducted based on the epidemic data from Chinese Infectious Disease Surveillance Reporting System, sentinel surveillance system in 6 provinces (Hunan, Guangxi, Anhui, Guizhou, Jiangsu and Shandong) and National Bureau of Statistics in 2017. Results: A total of 516 human rabies cases, including 502 deaths, were reported by 27 provinces in 2017 with the morbidity rate and mortality rate of 0.037/100 000 and 0.036/100 000, respectively. The case number and death number decreased by 19.88% (128/644) and 15.20% (90/592) respectively compared with 2016. Rabies epidemics were mainly found in southern and central areas. The first 5 provinces reporting high case numbers were Hunan (71 cases), Henan (52 cases), Guangxi (41 cases), Anhui (39 cases) and Hubei (39 cases), their cases accounted for 46.90% (242/516) of the total reported cases in China. Rabies mainly occurred in summer and autumn, and the majority of patients were farmers, students and children outside child care settings. The male to female ratio of the cases was 2.46 ∶ 1 (367 ∶ 149). Cases was reported in all age groups, and more cases occurred in middle aged and old adults than in adolescents. Questionnaires survey was conducted for 186 cases, the results indicated that 94.89% (167/176) of exposures were caused by dog bites. The exposure degree was mainly category Ⅲ, accounting for 68.86% (115/167), and only 6.02% (10/166) of cases were immunized after exposure. The median of latent period of these cases was 72 days. Conclusions: By 2017, the human rabies incidence in China had declined consecutively for ten years, more cases were reported in southern area than in northern area. The case number showed downward trends in provinces with high incidences and fluctuant increase in provinces with low incidence. Rabies cases mainly occurred in rural areas, and most cases were men and farmers. Low rate of post exposure prophylaxis, low rates of vaccination and passive immunization product injection were main causes for the onset of human rabies. It is necessary to strengthen the surveillance for human rabies, especially in rural areas, health education about treatment after rabies exposure and expend the coverage of canine immunization.

RESUMO

OBJECTIVE: To determine the associations between the family history of rheumatic diseases and clinical features in patients with rheumatoid arthritis (RA). METHODS: In total, eight hundred and ninety patients with RA were enrolled. The demographic and clinical data were collected, including gender, age, height, body weight, age of disease onset, history of smoking and drinking, family history of rheumatic diseases, clinical and laboratory features, pain and global visual analogue scale (VAS), and multi-dimensional health assessment questionnaire (MDHAQ). Finally, 803 patients were completed the dataset and were included in the study. RESULTS: In this cohort, the male/female ratio was 1:3.5, and the age of onset was (45.09±14.50) years. A total of 123 (15.32%) patients were accompanied with family history of rheumatic diseases, including RA, spondyloarthritis, Sjögren's syndrome, systemic lupus erythematosus and systemic sclerosis. The percentages of first degree, second degree and both first and second degree relatives were 91 (73.98%), 22 (17.89%), and 10 (8.13%) respectively. The most common disease was RA (70.73%), followed by other rheumatic diseases (21.95%), and RA combined with other rheumatic diseases (7.32%). The clinical and laboratory characteristics were compared between the patients with and without family history. The onset-age of the subjects was significantly different between those with and without family history of rheumatic diseases (39.97 ±13.68 vs. 46.01±14.46; P<0.01), which meant that the onset-age in patients with family history was 6.04 years earlier than that in patients without family history. The patients with family history had higher positive rate of rheumatoid factor (RF) compared with those without family history (78.48% vs. 66.67%, P<0.05). By adjusting with gender, body mass index (BMI), smoking and alcohol drinking, anti-cyclic citrullinated peptide (CCP) antibody and RF level, the age at disease onset in the patients with family history was 4.54 years earlier than that in the patients without family history (ß=-4.54; 95%CI:-8.70, -0.38; P<0.05). Further hierarchical regression analysis showed that, the age at onset of the RA patients with family history was 10.02 years earlier than that without family history among the smoking patients (ß= -10.02; 95%CI:-17.60, -2.43; P=0.01), while the age at onset of the RA patients with family history was 3.27 years earlier than that without family history among the never smoking patients (ß=-3.27; 95%CI:-8.37, 1.82; P=0.21). CONCLUSION: The family history of rheumatic diseases is a risk factor for early onset of RA, and may interact with smoking.

RESUMO

Objective: To investigate the safety and feasibility of laparoscopic operation in thetreatment of gastric gastrointestinal stromal tumor (GIST) at unfavorable positions. Methods: A retrospective cohort study was conducted to analyze the clinical data of patients with gastric GIST at unfavorable positions confirmed by pathology after surgery (laparoscopy or laparotomy) at the Southwest Hospital of the Army Medical University and the Minda Hospital of Hubei Minzu University from June 2008 to June 2018. The unfavorable positions of stomach are defined as the esophagogastric junction, the proximal cardia of gastric lesser curvature, the pylorus of stomach, the posterior wall of stomach and the antrum of stomach.Exclusion criteria:(1) preoperative chemotherapy or imatinib therapy; (2) diameter of tumor > 10 cm; (3) tumor metastasis or concurrence of other malignant tumors. A total of 244 patients (238 in Southwest Hospital and 6 in Minda Hospital) were enrolled, including 122 males and 122 females with age of 41-70years. Operative methods should be adopted according to patients' wishes. There were 146 cases in the laparoscopic surgery group and98 cases in the open surgery group. The intraoperative blood loss, operative time, postoperative first flatus time, postoperative firstfeeding time,average hospital stay, morbidity of postoperative complication,1-,3-,and 5-year recurrence free survival(RFS) and overall survival (OS)rate were compared between the two groups. Results: There were no significant differences in sex, age, tumor size, tumor risk grade or growth pattern between the laparoscopic and the open surgery groups (all P>0.05),and these two groups were comparable. Compared with open group, laparoscopic group had less intraoperative blood loss [(31.4±2.3) ml vs. (143.9±3.7) ml, t=292.800, P<0.001], shorter postoperative first flatus time [(2.1±0.7) days vs.(3.8±0.8) days, t=17.550,P<0.001], shorter postoperative first feeding time [(2.1±0.5) days vs.(2.3±1.7) days, t=1.339,P=0.020], shorter hospital stay [(8.6±2.6) days vs. (13.6±3.2) days, t=13.410, P<0.001], and lower morbidity of postoperative complication [16(11.0%) vs. 21(21.4%),χ2=4.996,P=0.025], whose differences were statistically significant. While the operation time was similar in two groups [(124.7±15.8) minutes vs. (120.9±14.5) minutes, t=1.903,P=0.058]. The median follow-up of all the patients was 43 (1 to 119) months.In laparoscopic group and open group, the 1-, 3- and 5-year RFS were 94.5% vs. 93.9%, 91.1% vs. 90.8%,and 82.2% vs. 81.6%, respectively, and 1-, 3- and 5-year OS were 98.6% vs. 95.9%, 95.9% vs. 94.9%,and 91.1% vs. 88.8%, respectively, whose differences were not statistically significant (all P>0.05). Conclusion: In the experienced gastrointestinal surgery center, laparoscopic resection of gastric GIST at unfavorable position is safe and feasible, achieving the same efficacy of open surgery.

RESUMO

OBJECTIVES: The aim of this study was to investigate the predictive factors for relapse of IgG4-related disease (IgG4-RD) and observe the long-term clinical outcomes in patients with IgG4-RD. METHODS: We included in the present analysis 122 patients who were newly diagnosed with IgG4-RD, treated with glucocorticoid (GC) monotherapy or GC and immunosuppressant combination therapy, and followed for at least 3 years. Clinical relapse, response and side effects were recorded. RESULTS: The cumulative relapse rates of patients in this study were 10.66%, 22.95% and 27.87% at 12, 24 and 36 months, respectively. Complete drug withdrawal was an independent risk factor for disease relapse. Higher serum IgG4 concentrations, involvement of more organs, higher IgG4 RI scores and elevation of eosinophils at baseline were closely associated with disease relapse. Re-elevation of serum IgG4 concentrations and low GC maintenance dosage during the follow-up period were significantly associated with clinical relapse. The GC dosage should be more than 6.25 mg day-1 as monotherapy during the maintenance stage; moreover, combining with immunosuppressants can reduce the GC dosage. Adding GC or immunosuppressants for patients with re-elevation of serum IgG4 levels could prevent later disease relapse. No serious complications were noted during long-term follow-up. CONCLUSIONS: The combination of GC with immunosuppressants was more effective than GC monotherapy during the steroid tapering and maintenance stages. Higher serum IgG4 levels, involvement of more organs, higher IgG4 RI scores, history of allergy, eosinophil elevation at baseline, re-elevation of serum IgG4 levels and lower GC maintenance dosage at follow-up might be predictive of relapse.

RESUMO

Objective: Breast cancer stem cells (BCSC) have been suggested to have clinical implications for cancer therapeutics because of their proposed role in chemo-resistance. The aim of this study was to investigate effects of BCSC on endocrine therapy response by regulating PI3K/Akt/mTOR signaling pathway. Methods: We evaluated the susceptibility of BCSC to NVP-BKM120 (BKM120), a new generation of PI3K-specific inhibitor, when used individually or in combination with letrozole in vivo. For this, a stem-like cell population (SC) was enriched from breast cancer cell line MCF-7 after mammosphere cultures. We have constructed high aromatase expression BCSC (BCSC-CYP19) and non-stem cells (MCF-7-CYP19) subcloning. We demonstrate BKM120 inhibits growth, generation of drug-resistant derivatives and SC formation in BCSC-CYP19 and MCF-7-CYP19. Result: BKM120 could inhibit BCSC-CYP19 growth by dose-dependence, reduce migration and colony formation of BCSC-CYP19, and also significantly reduced expression of PI3K, Akt1 and S6. Combined BKM120 and letrozolecaninhibit BCSC-CYP19 growth and proliferation, make BCSC-CYP19 stayed in G0-G1 phase increasing significantly to induce early apoptosis, and down-regulate expression of PI3K, Akt1 and S6. Conclusion: PI3K/Akt/mTOR pathway effects on letrozole resistance by regulating BCBSs characteristics. Combination of PI3K inhibitor BKM120 and letrozole could reduce letrozole resistance.

RESUMO

BACKGROUND: TCS (topical corticosteroids) are the first-line drug in the treatment of oral lichen planus (OLP). However, the value of topical calcineurin inhibitors (TCI) including tacrolimus, pimecrolimus and ciclosporin for OLP is still controversial. OBJECTIVES: To compare the efficacy and safety of TCI vs. TCS for OLP. METHODS: The authors searched PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science and four Chinese databases from 1950 to May 2018. The randomized controlled trials comparing TCI and TCS for OLP reported at least one of the following outcomes: improvement of clinical signs and/or symptoms, relapse, blood levels of TCI and adverse events. RESULTS: Twenty-one trials involving 965 patients were included in the analysis. For the treatment of OLP (3-8 weeks), TCI including tacrolimus, pimecrolimus and ciclosporin were similar to TCS in efficacy. Tacrolimus-TCS resulted in similar outcomes, with relapse at 3 weeks to 6 months. Blood levels of TCI were usually undetectable. In addition, tacrolimus showed a statistically higher incidence of local adverse events than TCS for short-term treatment. A few systemic adverse events occurred in the tacrolimus and ciclosporin groups, but they were not serious. CONCLUSIONS: The evidence for tacrolimus (n = 12), pimecrolimus (n = 3) and ciclosporin (n = 6) demonstrated that treatment with TCI may be an alternative approach when OLP does not respond to the standard protocols. Tacrolimus 0·1% should be the first drug of choice when selecting TCI for short-term treatment in recalcitrant OLP. Further well-designed trials are warranted to evaluate the long-term efficacy and safety of TCI. What's already known about this topic? The main topical drug for oral lichen planus (OLP) is topical corticosteroids (TCS). Patients with OLP who are not responsive to TCS or are at risk of adverse events from TCS need other alternative drugs. Topical calcineurin inhibitors (TCI), including tacrolimus, pimecrolimus and ciclosporin, have become a hot topic in a variety of mucocutaneous immune-mediated diseases. What does this study add? TCI including tacrolimus, pimecrolimus and ciclosporin were similar to TCS in efficacy for the short-term treatment of OLP. The local adverse events of tacrolimus were higher than with TCS. A few systemic adverse events were reported with TCI, but they were all tolerable and not serious. The limited evidence for pimecrolimus (three trials) and ciclosporin (six trials) requires further studies to evaluate the short-term and long-term efficacy and safety of TCI compared with TCS.

RESUMO

OBJECTIVE: The aim of this study was to investigate the influence of micro-ribonucleic acid-34a (miR-34a) on preeclampsia through the Notch signaling pathway. PATIENTS AND METHODS: The expressions of miR-34a, Notch-1, Notch-2, and Notch-3 in the placenta of 39 preeclampsia patients and 42 normal patients were detected by immunohistochemistry and Reverse Transcription-Polymerase Chain Reaction (RT-PCR). The correlations between miR-34a expression with the expressions of Notch-1, Notch-2 and Notch-3 were analyzed, respectively. Besides, placental trophoblasts were isolated from preeclampsia patients and cultured in vitro. The expressions of miR-34a, Notch-1, Notch-2 and Notch-3 in placental trophoblasts were analyzed. Furthermore, the influences of miR-34a on the protein expressions of Notch-1, Notch-2, Notch-3, and hairy and enhancer of split-1 (Hes-1) in the Notch signaling pathway were analyzed by Luciferase reporter gene assay and Western blotting. The role of Notch in trophoblast invasion was investigated through the Notch inhibitors. In addition, its influence on the expression of urokinase-type plasminogen activator (uPA) was studied by miR-34a overexpression. RESULTS: The expressions of miR-34a and Notch-1 were correlated with preeclampsia in the placentas of preeclampsia patients and normal patients to a certain degree. The expression of miR-34a in preeclamptic placenta was significantly higher than that of the normal placenta (p<0.05). However, Notch-1 expression was markedly lower in preeclamptic placenta (p<0.05). No significant differences were found in the expressions of Notch-2 and Notch-3 between the two types of placentas (p>0.05). MiR-34a had a remarkable negative correlation with Notch-1 expression in the Notch family (p<0.001, r=-0.5775). RT-PCR results revealed that the mRNA expression of miR-34a in placental trophoblasts of patients with preeclampsia was notably higher than that of normal people (p<0.01). However, Western blotting demonstrated that the protein expressions of Notch-1, Notch-2 and Notch-3 exhibited the opposite results. Additionally, the protein expression of Notch-1, Notch-2, Notch-3 and Hes-1 in trophoblasts transfected with pre-miR-34a was significantly decreased. The treatment with Notch inhibitors markedly reduced the trophoblast invasion. Furthermore, miR-34a overexpression or intracellular domain of Notch (ICN) overexpression regulated uPA expression. CONCLUSIONS: MiR-34a regulates uPA system through the Notch signal transduction, thereby regulating the invasion of placental trophoblasts in patients with preeclampsia.

RESUMO

Objective: To investigate the correlation between blood pressure variability (BPV) and target organ damage in children with essential hypertension. Methods: A retrospective review identified 144 children (104 boys (72.2%) and 40 girls (27.8%), age (11.7±2.5)years) diagnosed with essential hypertension at Children's Hospital Affiliated to Capital Institute of Pediatrics from January 2013 to June 2018. Data on indicators for assessing fundus, cardiac, and renal damages obtained included 24-hour ambulatory blood pressure monitoring, BPV, fundus oculi examination, electrocardiogram, echocardiography, renal function, 24-hour urine protein quantitation, urine microalbumin, serum and urine ß(2)-microglobulin. According to the existence of target organ damage, subjects were divided into target organ damage group and non-target organ damage group. Comparison between groups was analyzed using independent sample t test, chi square test and pearson correlation analysis. Results: The study included 144 children. There were 108 children (75.0%) diagnosed with phase 1 hypertension and 36 children (25.0%) diagnosed with phase 2 hypertension. Patients in target organ damage group (n=86, 59.7%) had a higher coefficient of 24 h diastolic BPV (14.5%±3.2% vs. 13.2%±2.5% t=2.558, P=0.012), a higher coefficient of daytime systolic BPV (8.2%±2.1% vs. 7.4%±2.0%, t=2.253, P=0.026) and a higher coefficient of daytime diastolic BPV (12.8%±3.4% vs.11.1%±2.4%, t=3.188, P=0.002) compared with patients in non-target organ damage group (n=58, 40.3%). The coefficients of daytime systolic BPV and daytime diastolic BPV were significantly associated with cardiac damage (r=0.190, P=0.023; r=0.366, P<0.01) and renal damage (r=0.167, P=0.046; r=0.167, P=0.045). The coefficient of daytime diastolic BPV was positively correlated with left ventricular mass index (r=0.366, P<0.01). Conclusions: There is a correlation between BPV and target organ damage in children with essential hypertension. Daytime BPV is strongly associated with cardiac and renal damage, and daytime diastolic BPV may predict early cardiac hypertrophy. As a noninvasive method, daytime BPV can provide evidence for early identification of hypertensive target organ damage.

RESUMO

AIM: To identify the basic characteristics and gene expression profiles of supernumerary teeth derived stem cells (SNTSCs) and compare them with those of normal dental pulp stem cells (DPSCs). METHODOLOGY: Flow cytometry was conducted to identify the protein expression of stem cell markers. Cell proliferation, migration and differentiation abilities of both SNTSCs and DPSCs were determined by CCK8, transwell and differentiation assays, respectively. Gene expression profiles were studied by RNA sequencing analyses. After knocking down the expression of certain differential expression genes (DEGs), the function of DEGs was investigated by CCK8 and transwell assays. Statistical differences were determined using a two-tailed t-test and P values below 0.05 were considered significant. RESULTS: Supernumerary teeth derived stem cells were capable of differentiating into adipocyte, chondrocyte and osteoblast lineage cells, and compared to ordinary DPSCs, SNTSCs had a significantly higher cell proliferation rate (P < 0.01) and significantly lower migration rate (P < 0.01). RNA-seq results revealed the differential expression genes (DEGs) between SNTSCs and DPSCs. A principal component analysis (PCA) and cluster analysis revealed that the gene expression patterns of SNTSCs and DPSCs were different from each other. A total of 12 861 genes were differentially expressed at a significant P value (P ≤ 0.01), and 5292 of these increased in SNTSCs and 7569 decreased. Further study on the selected DEGs revealed that FUT11, FAM155A and BRD2 inhibited the cell proliferation rate of SNTSCs, and FUT11 and GLUD1 inhibited the cell migration rate, whilst FAM155A promoted the migration rate. CONCLUSIONS: The biological characteristics and gene expression profile of SNTSCs was revealed. The stem cell properties of SNTSCs were similar to normal DPSCs but they had a high cell proliferation rate and may have greater potential for cell differentiation.

RESUMO

Objective: To study the prevalence of musculoskeletal disorders (MSDs) and related factors in female greenhouse workers. Method: A questionnaire survey was conducted among 851 female greenhouse workers in Shandong province in 2015. Results: The incidence of MSDs among the female greenhouse workers was 82.79%. For the MSDs in female greenhouse workers, the top four affected body sites were low back (65.82%), knees (49.10%), neck (25.75%) and shoulder (23.47%). Multivariate logistic regression analysis showed that age ≥50 years (OR=2.098, 95%CI: 1.353-3.252), working years ≥20 (OR=1.703, 95%CI: 1.116-2.599), repetitive work (OR=1.903, 95%CI: 1.183-3.061), standing for prolonged time (OR=2.902, 95%CI: 1.183-7.120) and frequent slightly bending down (OR=2.979, 95%CI: 1.823-4.867) were the main risk factors for MSDs in female greenhouse workers. Aiding tools was the protective factor (OR=0.400, 95%CI:0.229-0.697). Conclusions: The findings showed a relatively higher prevalence of MSDs in female greenhouse workers. It is necessary to take appropriate measures to prevent and control the incidence of MSDs in female greenhouse workers.

RESUMO

OBJECTIVE: High blood pressure (hypertension) is one of the most common cardiovascular diseases. In recent years, there were more and more studies on the function of inflammation in hypertension. CD68 mainly mediates the activation of cytokine interleukin-17 (IL-17) signaling pathway and participates in inflammatory responses. It has been studied the function of CD68 and IL-17 in hypertension, but it has not been reported whether it affected hypertension and vascular remodeling when macrophage CD68 expression inhibited. In this study, antisense-CD68 mice were used to study the effect and mechanism of angiotensin II-induced hypertensive vascular remodeling under specific suppression of macrophage CD68. MATERIALS AND METHODS: Fifty 8-week-old male antisense-CD681 and C57 mice were divided into control and experimental group (angiotensin II group, 1000 ng•kg-1•min-1). After infusion of angiotensin II for 28 days, hematoxylin-eosin (HE) staining and immunohistochemical staining were used to observe the remodel of vascular. The changes of aortic inflammatory factors were detected by Real-time PCR (RT-PCR) and Western blotting. RESULTS: By specifically inhibiting the expression of macrophage CD68, macrophage infiltration was mitigated in Ang II-induced hypertensive vascular remodeling model mouse, which also down-regulated the expression of vascular tissue inflammatory factor and activation of vascular smooth muscle cell p65. CONCLUSIONS: CD68 regulates the Ang II-induced hypertensive vascular remodeling through mediating macrophage inflammatory factor release.

RESUMO

Objective: To investigate DNA damage in the transformed human bronchial epithelial cells (16HBE) induced by hexavalent chromium (Cr(6+)) and further elucidate the potential carcinogenesis mechanism of Cr(6+). Methods: 16HBE were treated with different concentration of Cr(6+ ()0, 0.625, 1.25, 2.5 µmol/L) for 15 weeks. The malignant degrees of transformed cells were identified by the assays for anchorage-independent growth and tumorigenicity. According to the single cell gel electrophoresis (SCGE) assay, the DNA damage rate was calculated. The expression level of 53BP1 was determined by Western blot. Results: Chromium-treated cells could form colonies in soft agar and tumors in nude mice. Compared with the control group, colony formation efficiency of 1.25µmol/L and 2.5 µmol/L Cr(6+)-treated cells in soft agar showed significant increases (p<0.05) . The 2.5 µmol/L Cr(6+)-treated cells also formed tumors subcutaneously in nude mice. Cr(6+) could cause different degree of DNA damage to 16HBE cells in a dose-dependent manner. In addition, Western blot analyses showed that 53BP1 was aberrantly down-regulated at 2.5 µmol/L dose and has no significant changes at 0.625 µmol/L and 1.25 µmol/L dose under the treatment of Cr(6+). Conclusion: The declined expression of 53BP1 may mediate Cr(6+)-induced DNA damage and further involved in the cell malignant transformation.

RESUMO

Objective: To explore the trichloroethylene-induced alteration of methylation on the promoter region of SET and related mechanisms in hepatic L-02 cells. Methods: L-02 cells were treated with different concentrations of TCE(0 mmol/L, 1 mmol/L, 2 mmol/L, 4 mmol/L, 8 mmol/L) for 24 h. The genomic DNA were then extracted and modified by bisulfite sodium. The DNA methylation was then analyzed using bisulfite sequencing PCR (BSP). Results: The overall methylation on promoter region of SET was decreased along with the increased concentrations of TCE in hepatic L-02 cells. Moreover, 73 CpG islands were found abnormally altered, among which 9 were predicted in transcriptional factor binding regions. Conclusion: The decreased levels of CpG islands in the transcriptional factor binding region may contribute to the elevation of SET in TCE-induced hepatotoxicity.

RESUMO

Objective: To investigate the effects ofepicardial adipose tissue volume (EATV) and inflammatory factors on left ventricular diastolic function in patients with coronary heart disease(CHD). Methods: The clinical data of patients with coronary heart disease receiving coronary artery intervention therapy from January 2014 to October 2015 in TEDA international cardiovascular hospital were preoperatively collected.We measured the indexes of EATV and left ventricular diastolic function. Results: The difference of age (F=7.76, P=0.01), IL-6 (F=14.34, P<0.01), Hs-CRP (F=4.08, P=0.04), adiponect-in (F=4.50, P=0.04) and EATV (F=71.29, P<0.01) between the diastolicdysfunction group (n=156) and the normal group (n=76) was statistically significant.Multivariate logistic regression analysis showed that EATV was a risk factor for left ventricular diastolic dysfunction in patients with coronary artery disease (P<0.05), OR=1.05, 95%CI (1.03-1.06). The AUC value of EATV in the diagnosis of left ventriculardiastolic function in patients with coronary heart disease was 0.79, 95%CI (0.73-0.85) P<0.01. Conclusions: EATV can be used as an independent risk factor for left ventricular diastolic dysfunction.It has some non-invasive diagnosis and predictive value, and it can be used as a new therapeutic target.
