ABSTRACT

Objective To investigate the clinical application value of pulp mummification therapy and root canal therapy in senile chronic pulpitis. Methods The clinical data of elderly patients with chronic pulpitis who were admitted to our department from January 2016 to January 2017 were analyzed retrospectively. According to the different treatment methods, 120 elderly patients were divided into two groups: the pulp mummification therapy group and the root canal group. The clinical efficacy of the two groups were observed and the patients were followed up for a period of six months. The prognosis of the patients was recorded and counted. Results There were 60 patients in the pulp mummification therapy group, of which 34 were markedly effective, 19 were effective and 7 were ineffective. There were 60 patients in the root canal treatment group, of which 33 were markedly effective, 17 effective and 10 ineffective. There was no significant difference between data of the two groups (P>0. 05). Six months after treatment, the patients were followed up for half a year. There were 2 adverse reaction cases in 60 patients of the pulp mummification therapy group. The incidence of adverse reactions was 3. 33%. Among the 60 patients in the root canal treatment group, 1 patient developed adverse reactions, The incidence of adverse reactions was 1. 67%. There was no difference in the incidence of adverse reactions between the two groups (P>0. 05). Conclusion Both pulp mummification therapy and root canal therapy have a good clinical effect on elderly patients with chronic pulpitis. However, the pulp mummification therapy is suitable for patients whose radicular pulp have not been infected and the root canal is suitable for patients whose radicular pulp have been infected. Therefore, appropriate treatment should be selected based on patient characteristics to improve the treatment effect during the process of treatment.

ABSTRACT

Objective To assess the impact of miR-429 on lung adenocarcinoma cell SPC-A1 growth inhibition.Methods Pre-miRTM miR-429 precursor was synthesized and transfected to the SPC-A1 cells by liposome; qRT-PCR assay was used to quantify the miR-429 expression levels; The proliferation of SPC-A1 cells was evaluated by Cell Counting Kit-8 (CCK8).The cell apoptosis was evaluated by Annexin V Assay; The cell cycles of each group were assayed by flow cytometry;Western-blot was used to analyze the expression of cylines.Results The expression level of miR-429 was highly induced after transfection (P < 0.001) ;CCK-8 assay showed the cell proliferation activity of pre-miR-429 group was lower than that of blank and control group 48h and 72 h after transfection(P =0.0167,0.0383,P =0.0320,0.0465),whereas the apoptosis rate had no significant difference between pre-miR-429 and control 24h after transfection by Annexin V Assay(P > 0.05) ; The flow cytometry at 48h after transfection showed that miR-429 decreased the percentage of cells in G1 phase,but increased in S phase,indicating the cell cycle arrest at S phase(P =0.0010,0.0010 ; P =0.0068,0.0133) ; however,the expression level of Cyclin E in pre-miR-429 group had no difference compared with control.Conclusion miR-429 could inhibit cell proliferation and promote cell cycle arrest of lung adenocarcinoma cell SPC-A1.miR-429 may play a potential tumor suppressor role in lung adenocarcinoma cell SPC-A1.

ABSTRACT

Objective To study the microbial strains,risk factors and resistance profiles of lower respiratory tract fungal infection in hospital of Zhoushan archipelago area.Methods A total of 204 patients who were hospitalized for lower respiratory tract infection were retrospectively analyzed from May 2008 to April 2011 in Zhoushan archipelago area,and collected 204 fungal strains isolated from confirmed lower respiratory tract fungal infection cases.Chi-square test and Logistic regression analysis were performed.Results Among the 204 fungal strains isolated from lower respiratory tract specimens,110 (53.8%) strains of Candidaalbicans,32 (15.7%) strains of Candida tropicalis,24 (11.8%) strains of Candida glabrata,12 (5.9%) strains of Candida krusei,14 (6.9%) strains of other Candida,and 12 (5.9%) strains of Aspergillus were detected.Logistic regression analysis showed that chronic obstructive pulmonary disease,bacterial pneumonia,long-term use of broadspectrum antibiotics and corticosteroids,endotracheal intubation or incision,old age,exposure in intensive care unit (ICU),and hospitalization ≥7 days were major risk factors (P=0.000,0.001,0.000,0.000,0.012,0.000,0.000,0.000).The resistance rates of isolated Candida against amphotericin B,5-flucytosine,voriconazole,itraconazole and fluconazole were 0,2.1%,4.2%,14.8% and 22.9%,respectively.Conclusions Candida albicans is the major pathogen of lower respiratory tract fungal infection in hospital of Zhoushan archipelago area,and Candida is sensitive to amphotericin B,5-flucytosine and voriconazole.

ABSTRACT

Objective To investigate iodine nutrition and thyroid health status among residents in Zhoushan archipelago, and to analyse their relationship.Methods A total of 3 284 residents in Zhoushan archipelago were surveyed by questionnaire and their thyroids were examined by B-mode ultrasound.The levels of urinary iodine and thyroid function were detected.Results The median level of urinary iodine in 3 284 residents was 226.0 μg/L, being 320.7 μg/L in citizens, 188.9 μg/L in farmers, 122.2 μg/L in salt-makers, 193.6 μg/L in fishers, and 271.7 μg/L in buddhist.The prevalence of diffuse goiter, nodular goiter, colloid goiter, thyroid adenoma, thyroid carcinoma, hyperthyroidism, subclinical hyperthyroidism, hypothyroidism, subclinical hypothyroidism, and positve rate of TPOAb were 1.7% ,25.3% ,8.7% ,0.2% ,0.4% ,0.5% ,0.8% ,0.03%,1.0% ,and 9.5% repectively.The prevalence of thyroid diseases was increasing with aging, and higher in women than in men (P<0.05).There was no significant relationship of the thyroid diseases with seafood, smoking,drinking, and tea (P>0.05).Conclusions The citizens of Zhoushan archipelago have adequate iodine intake.It is pertinent to discuss Universal Salt Iodization.Excessive iodine intake may contribute to the high prevalence rate of thyroid diseases in Zhoushan.
