RESUMO
Objective:To explore the application value of radical prostatectomy(RP) combined with extented pelvic lymph node dissection(ePLND) in patients with clinically localized prostate adenocarcinoma.Methods:We searched the PubMed, Embase, Cochrane Library databases, the China Knowledge Network(CNKI) database, Wanfang database, Chinese Biomedical Literature Database by computer.The following MeSH terms and their combinations were searched in English and Chinese, respectively: prostate neoplasms, prostate neoplasm, prostatic neoplasm, prostate cancer, prostate cancers, cancer of the prostate, prostatic cancer, prostatic cancers, cancer of prostate, lymph node excisions, lymphadenectomy; lymphadenectomies, lymph node dissections, radical prostatectomy, extent, extented, standard, standardized, limit, limited; prostate cancer, radical prostatectomy, lymph node dissections.The search was set for all case-control studies on the comparison in patients with clinically localized prostate cancer beteeen RP with ePLND with standard (sPLND) or limited PLND(lPLND). Two authors independently screened the literature, extracted relevant literature data, and evaluated the quality of the literature.The software Revman 5.3 and Stata 12.0 were used to perform meta-analysis in this study. The software R 3.6.0 was used to combine the total survival curves. The limited template was included in the sPLND for comparison.Results:Fourteen studies with a total of 12, 148 patients were included.Compared with sPLND, ePLND significantly improved lymph node yield(LNY)( WMD=9.72, 95% CI 6.81-12.63, P<0.05) and the detection of more lymph node positivity of metastasis(LN+ )( RR=2.89, 95% CI 2.16-3.86, P<0.00001). ePLND increased the complication rate, but the differences were not statistically significant( RR=1.39, 95% CI 0.95-2.05, P=0.09). The ePLND group had significantly lower biochemical recurrence(BCR)( RR=0.69, 95% CI 0.52-0.91, P=0.01) and higher biochemical-free survival( HR=0.59, 95% CI 0.56-0.63, P<0.05). Meanwhile, according to the overall survival, the two groups of curves became more and more distant over time( HR=0.59, 95% CI 0.56-0.63, P<0.05). Conlucsions:Compared with sPLND, RP combined with ePLDN could be more effective than standard PLND in patients with clinically localized prostate cancer and provides a better prognosis.
RESUMO
Objective@#To understand the prevalence of HIV (human immunodeficiency virus) testing and associated factors among sexual active college students in Zhuhai City.@*Methods@#From November to December, 2019, an anonymous electronic questionnaire was administered among 12 235 students in six colleges and universities in Zhuhai City by multistage sampling. A total of 1 789 college students ever had sex were selected. Pearsons Chisquare test and nonconditional Logistic regression model were applied to analyze the factors associated with uptake of HIV testing.@*Results@#Among these students ever had sex, 7.55% (135/1 789) had been tested for HIV mainly through hospitals (71.85%). The main reasons for testing were regular testing (50.37%) and intending to know their infection status (23.70%). Multivariable Logistic regression showed that homosexual individuals (OR=4.62, 95%CI=1.07-19.95) and those who had heterosexual commercial sex in the past year (OR=3.77, 95%CI=1.96-7.26) were more likely to test for HIV, while female (OR=0.41, 95%CI=0.24-0.69) were less likely to test for HIV.@*Conclusion@#The proportion of HIV testing was low among sexual active college students in Zhuhai City. Interventions should be tailored including strengthening the HIV testing propaganda education and enhancing students awareness of HIV testing, and the influencing factors such as gender, sexual orientation and commercial sexual behavior should be taken into consideration, so as to improve the HIV testing coverage of this population.
RESUMO
Objective:To investigate the preventive efficacy of pirfenidone in esophageal stent-related restenosis and the related underlying mechanisms.Methods:Twenty-four rats underwent esophageal stent placement were included in this study. The rats were randomly assigned to three groups, with 8 rats in each group. The three groups were set to receive placebo, 150 mg/kg pirfenidone and 300 mg/kg pirfenidone daily by oral administration for 28 days, respectively. Twenty-eight days after stent placement, the stented esophagi were harvested for histological examinations. The number of epithelial layers, the thickness of submucosal fibrosis, the percentage of granulation tissue area, the degree of inflammatory cell infiltration, the degree of collagen deposition, and the α-SMA staining scores were evaluated. One-way ANOVA was performed for the statistical comparison of the number of epithelial layers, the degree of inflammatory cell infiltration, the degree of collagen deposition and the α-SMA staining scores among these three groups. The Kruskal-Wallis H test was used for comparison of the thickness of submucosal fibrosis and the percentage of granulation tissue area among the three groups. Results:Gross pathological findings showed that both pirfenidone groups had significantly less luminal fibrotic tissue formation and restenosis than placebo group. The percentage of granulation tissue areas in placebo group, 150 mg/kg and 300 mg/kg pirfenidone groups were 57.23%±25.68%, 21.80%±6.65% and 12.18%±6.37%, respectively. Both pirfenidone groups showed significantly less granulation tissue areas than placebo group ( P<0.01). The degree of inflammatory cell infiltration, the degree of collagen deposition and the α-SMA staining scores were 3.28±0.55, 3.38±0.63 and 2.75±0.38 in placebo group, 2.30±0.46, 2.36±0.58 and 2.00±0.42 in 150 mg/kg pirfenidone group, and 1.86±0.38, 1.91±0.41 and 1.57±0.28 in 300 mg/kg pirfenidone group, respectively. Both pirfenidone groups showed significantly less inflammatory cell infiltration, collagen deposition and α-SMA staining scores than placebo group ( P<0.01). Conclusion:Pirfenidone can suppress esophageal stent-related restenosis in rats by significantly inhibiting inflammation, myofibroblast activation and proliferation, and fibrotic tissue formation.

RESUMO
Objective To investigate the long?term outcomes of posterior long segment instrumentation and fusion in adult degenerative scoliosis (ADS), and to explore the correlative factors of sagittal imbalance after long segment instrumentation and fusion, and to summarize the impacts of different lowest instrumented vertebra (LIV) on sagittal complication rates. Meth?ods ADS patients who underwent long segment instrumentation and fusion between January 2008 and January 2014 were retro?spectively reviewed and divided into two groups depended on LIV (L 5 group and S1 group). The follow?up time was at least five years. Radiographic parameters, Visual Analogue Score (VAS),Oswestry Disability Indexscore(ODI), the 12?item Short Form Health Survey?Physical Component Summary (SF?12 PCS)and sagittal complications were analyzed.And the correlation between sagittal imbalance and sagittal complications were calculated. Patients were divided into two groups(sagittal imbalance group and sagittal balance group) to explore the correlative factors of sagittal imbalance. Results All of 56 patients were included and evaluat? ed in this study, and 35 cases stopped at L 5, 21 cases at S1. The mean follow?up time was 6.6±1.6 years. No significant difference were found in age, gender, follow?up time and surgery method (P>0.05) between two groups.No significant differences were found in Cobb angle(11.8°±7.3°vs 12.6°±6.4°), coronal balance distance(CBD) (0.7±0.6 cm vs 1.0±0.5 cm), sagittal vertebral axis (SVA)(3.0±3.1 cm vs 2.6±5.6 cm), thoracic kyphosis(TK) (21.4°±9.6°vs 22.5°±6.9°), lumbar lordosis(LL) (-32.7°±7.3°vs -34.8°± 9.1°), pelvic tilt (PT) (23.4°±9.8°vs 23.3°±8.1°), VAS score(2.0±1.2 vs. 2.2±0.9), ODI score(18.5%±6.4% vs 19.3%±5.2%) and SF?12 PCSscore(45.5±5.2 vs 42.4±7.0) between two groups at final follow?up time( P>0.05). Radiographic parameters including Cobb angle, CBD, SVA and health related quality of life scores including VAS score, ODI score and SF?12 PCS scores were improved significantly at two weeks postoperatively, two?year follow?up time andfinal follow?up time in two groupscompared with those preop?eratively (P<0.05). And no significant difference were found in radiographic parameters and health related quality of life scores be?tween those at two years follow?up time and those at final follow?up time; Sagittal complication rates at final follow?up were higher than these at two years follow?up (82.1% vs 33.9%, P=0.000). Sagittal imbalance was related to internal fixation failure in L 5 group (r=0.691, P=0.011), internal fixation failure in S1 group (r=0.691, P=0.001) and pseudoarticulation formation (r=0.499, P=0.021). 10 patients in the sagittal imbalance group were with preoperative sagittal imbalance, 9 with preoperative coronal imbalance, 6 with internal fixation failure, 5 with proximal junctional kyphosis (PJK), 4 with adjacent segment degeneration during the follow?up periods, the incidence rates of which were higher than those in the sagittal balance group. LL in the sagittal imbalance group was lower than that in the sagittal balance group at two years follow?up time and final follow?up time. Compared with the sagittal imbal?ance group, the sagittal balance group achieved a higher SF?12 PCS (45.4 ± 5.1 vs 41.6 ± 7.4, P<0.05) and lower ODI scores (17.8%±6.1% vs 21.5±4.6%, P<0.05), and no significant difference was found in VAS scores between two groups (1.9±1.2 vs 2.4± 0.8, P>0.05). The incidence of adjacent segment degeneration in L 5 group was higher than that in S1 group (P<0.05) at final follow?up time, and the incidence of pseudojoint in S1 group was higher than that in L 5 group (P=0.002) at final follow?up time. Conclu?sion Posterior long segment instrumentation and fusion for adult degenerative spinal deformity can obtain satisfying long?term clinical outcomes, and postoperative sagittal imbalance was related to preoperative sagittal/coronal imbalance, postoperativein?ternal fixation failure, PJK, pseudoarticulation formation and adjacent segment degeneration. Distal fusion at L 5 or S1 may lead to high risk of adjacent segment degeneration or pseudoarticulation formation respectively.
RESUMO
Objective@#Through the bibliometrics analysis, to understand the research status quo and trend of the application of gamification in health management.@*Methods@#Based on the Web of Science Core Collection, We retrieved the article, review and proceedings paper published from 1900 to 2018 and analyzed literature retrieved in term of document types, publication years, authors, and funding agencies. In addition, VOSviewer1.6.9 was used for visualization analysis of keywords and countries/regions.@*Results@#A total of 364 pieces of literature were retrieved, of which 177 (48.63%) pieces were article. Since 2013, the number of literature has shown an upward trend at a rapid speed. However, only 16.48% of the literature were published by high productivity authors, which means a core group of authors has not yet formed in this research direction. The United States published the most literature, 89 pieces. Seven of the top ten funding agencies by volume were belong to the United Kingdom. However, only 10 pieces of literature were published by China. A total of 55 high-frequency keywords were included in this study, forming 5 research topics: physical activities management of adolescent based on mobile devices; internet-based behavior and mental health management for older-adults; design and application of fitness games; intervention and promotion of youth health behavior; the application of mobile health in adult self-management. The new high frequency keywords included older-adults, adults, mental health etc.@*Conclusion@#The application of gamification in health management is in its infancy, but it develops rapidly. European and American countries are in a leading position, while China is relatively backward. The research topics tend to be diversified and gamification is initially applied to the older-adults, adults and mental health management. In the future, the application scope of gamification in health management should be further expanded and effectively combined gamification with mHealth.

RESUMO
Objective@#Using Meta-analysis to evaluate the association between the short-term exposure to fine particular matter (PM2.5) and the morbidity of ischemic heart disease (IHD). @*Methods@#In this paper, "particulate matter" , "PM2.5" , "ischemic heart disease" , "coronary heart disease" , "coronary artery disease" , "atherosclerotic heart disease" , and "atherosclerotic cardiovascular disease" were used to systematically search for the literature on the association between the short-term exposure to PM2.5 and the ischemic heart disease through China Biology Medicine disc (CBMdisc), China National Knowledge Infrastructure (CNKI), Wanfang, Vip as well as Pubmed and Web of Science. The time was up to January 31st 2019. The quality of literature was evaluated by the Newcastle-Ottawa Scale. Meta-analysis method was performed by using R3.5.0 software and was used to perform heterogeneity test, calculate combined risk of IHD with short-term exposure to PM2.5 and carry out publication bias test. @*Results@#A total of 1 424 literatures were retrieved. Of the 23 literatures included studies (2 literatures in Chinese and 21 literatures in English) according to the inclusion and exclusion criteria, 14 used a time-series design and 9 used a case-crossover design. The heterogeneity existed across all identified studies (I2=81%, P<0.05). The Random effect model showed that a 10 μg/m3 increase in PM2.5 was associated with estimated relative risk of IHD morbidity at 1.007 (95%CI: 1.005-1.009); Publication bias was noted in the analysis (t=2.76, P<0.05), and the combined effect values of IHD morbidity was reduced to 1.005(95%CI: 1.004-1.007) after adjusting for asymmetry. @*Conclusion@#Short-term exposure to PM2.5 may lead to the increase of ischemic heart disease morbidity.
RESUMO
Objective To evaluate the clinical outcome of anterolateral lumbar interbody fusion (ALLIF) for the treat-ment of degenerative lumbar spondylolisthesis(DLS). Methods All of 53 patients with degenerative spondylolisthesis were en-rolled in this study during January 2014 to January 2016. All patients underwent stand-alone ALLIF with self-locked cage, includ-ing 15 males and 38 females with an average of 57.4±11.2 years old. The surgical level included L3,4(4 cases), L4,5(33 cases) and L5S1(16 cases). The operative time, bleed loss and complications were recorded. Clinical outcome was measured by visual analogue scale (VAS), Oswestry disability index (ODI) and the health questionnaire (SF-36). Radiological measures were slippage, disc height, lumbar lordosis, sagittal diameter and area of dural canal, foraminal height and area, and fusion rate. All the data were sta-tistically analyzed. Results All patients were followed up for at least 24 months. The mean operation time was 64.2 ± 12.5 min-utes, and the mean bleed loss was 72.8 ± 14.3 ml. No serious complications such as vascular or nerve injury occurred during peri operation. VAS for low back pain,VAS for leg pain and ODI were significantly decreased from 6.8 ± 1.5,5.6 ± 2.4 and 58.5％± 18.6％preoperatively to 1.6±1.2, 1.2±1.1 and 18.5％±8.8％at 24 months postoperatively.The SF-36 scores were improved signif-icantly from 56.7 ± 12.8 preoperatively to 79.4 ± 14.3 at 24 months postoperatively. Slippage of patients was reduced significantly from 22.5％± 8.3％preoperatively to 5.7％± 2.3％. Disc height and lumbar lordosis were significantly increased from 6.2 ± 1.6 mm and 46.4°±9.2° preoperatively to 10.5±1.4 mm and 53.2°±11.2° at 24 months postoperatively. Sagittal diameter and cross-section-al area of thecal sac were significantly increased from 11.7±2.2 mm and 78.4±28.6 mm2 preoperatively to 13.8±1.6 mm and 112.5± 23.9 mm2 at 6 months postoperatively. Intervertebral foramina height and area were significantly increased from 15.8 ± 4.3 mm and 136.5±25.6 mm2 preoperatively to 19.2±2.5 mm and 157.6±23.1 mm2 at 6 months postoperatively. At 24 months follow-up, the fusion rate was 100％and the subsidence rate was 10.5％. Conclusion Stand-alone ALLIF could achieve satisfactory clinical re-sults and reduction for DLS. Disc height and lumbar lordosis were restored. Efficient decompression was obtained with significant-ly increased sagittal diameter and cross-sectional area of thecal sac and intervertebral foramina height and area. Stand-alone AL-LIF provides a new surgical strategy for the treatment of DLS.

RESUMO
OBJECTIVE:To investigate the effects of olmesartan medoxomil on cardiac function,plasma N-terminal pro-brain natriuretic peptide(NT-proBNP)and serum interleukin-23(IL-23)in patients with chronic heart failure(CHF),and to evaluation its safety. METHODS:A total of 40 CHF patients selected from Lianshui County People's Hospital of Jiangsu Province during Dec. 2014-May 2016 were divided into control group and observation group according to random number table,with 20 cases in each group. Control group was given Enalapril maleate tablets with initial dose of 5 mg,po,qd(increasing gradually after one week,limiting dose of 20 mg/d)+Metoprolol tartrate tablets 25 mg,po,bid+Isosorbide mononitrate tablets 40 mg,po,qd+Furose-mide tablets 20 mg,po,bid. Observation group was additionally given Olmesartan medoxomil tablets 20 mg,po,qd,on the basis of control group. Both groups received treatment for consecutive 8 weeks. Cardiac function indexes [LVEDD,LAD,IVST,LVP-WT,LVEF,early diastolic peak E filling velocity/late diastolic peak A filling velocity(E/A)],plasma NT-proBNP and serum IL-23 levels were observed in 2 groups before and after treatment. The incidence of ADR was recorded. RESULTS:Before treat-ment,there was no statistical significance in cardiac function indexes,plasma NT-proBNP or serum IL-23 levels between 2 groups (P>0.05).After treatment,LVEDD,LAD,plasma NT-proBNP and serum IL-23 levels of 2 groups were decreased significantly, while LVEF and E/A levels were increased significantly;the observation group was significantly better than control group,with sta-tistical significance(P<0.05). There was no statistical significance in IVST or LVPWT levels between 2 groups before and after treatment,and there was no statistical significance in the incidence of ADR between observation group(25.00%)and control group(20.00%)(P>0.05). CONCLUSIONS:Olmesartan medoxomil can decrease the levels of plasma NT-proBNP and serum IL-23 in CHF patients,and improve cardiac function with good safety.
RESUMO
Objective The purpose of this work was to compare the efficacy of narrow band imaging-assisted transurethral resection of bladder tumour (TURB) with conventional white light imagingassisted TURB in primary non-muscle-invasive bladder cancer.Methods Several databases were searched,including Cochrance Libarary,PubMed,Embase,Wanfang,VIP,CNKI and CBM.The endpoints were biochemical failure in 3 months,1 year and 2 years.We performed a meta-analysis of the published data.The results are expressed as risk ratio (RR),with the corresponding 95％ confidence interval (CI).Results The final analysis included seven trials comprising 1889 patients.Biochemical failure in 3months (RR0.73,95％ CI 0.55-0.96;P =0.02),1 year(RR 0.69,95％ CI 0.58-0.80;P ＜ 0.01) and 2 years (RR 0.58,95％ CI 0.41-0.82;P =0.002) were fewer in patients who received narrow band imagingassisted TURB.The recurrence rates of 3 months,1 year and 2 years were 14.44％,29.35％ and 30％ in white light imaging group.The recurrence rates of 3 months,1 year and 2 years were 3.61％,9.35％ and 12.59％ lower in narrow band imaging group compared with white light imaging group.Conclusions Narrow band imaging-assisted TURB was superior to conventional white light imaging-assisted TURB in primary non-muscle-invasive bladder cancer in 2 years.

Objective:To modify Ganodermalucidum polysaccharides(GLP) with sulfate and observe the protective effect of Ganodermalucidum polysaccharide sulfate (GLPS) on the cerebral ischemia reperfusion injury in the rats,and to investigate its mechanism.Methods:GLP was modified by sulfation to obtain GLPS.A total of 100 SD rats were randomly divided into sham operation group, model group, GLP group (40 mg·kg-1·d-1), GLPS group (40 mg·kg-1·d-1) and nimodipine group (1 mg·kg-1·d-1).The cerebral ischemia reperfusion models were established by middle cerebral artery occlusion method in the rats.The neurologic deficit score and the content of water in brain tissue of the rats with cerebral ischemia reperfusion injury were detected and the activities of superoxide dismutase(SOD) and the levels of malondialdehyde (MDA) were detected.The levels of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB),tumor necrosis factor-alpha (TNF-α), interleukin-1 (IL-1) and interleukin-6 (IL-6) in the brain tissue homogenate were detected by ELISA.Western blotting method was used to detect the protein expression levels of HSP70 and p-Akt in the brain tissue of the rats.Results:Compared with model group, the neurological function scores of the rats in GLP group and GLPS group were decreased(P<0.01),the water contents in brain tissue were decreased(P<0.05), the SOD activities were increased and the MDA levels were decreased(P<0.05), and the levels of NF-κB, TNF-α, IL-1 and IL-6 were decreased(P<0.05);the effect in GLPS group was significantly better than that in GLP group(P<0.05).The results of Western blotting method showed that the p-Akt protein expression levels in the brain tissue of the rats in GLP and GLPS groups were increased compared with model group (P<0.05);compared with model group, the HSP-70 protein expression level in the brain tissue of the rats in GLPS group was increased(P<0.01),but the effect in GLP group was not obvious.Conclusion:Sulfation can significantly improve the protective effect of GLP on the cerebral ischemia reperfusion injury in the rats and its mechanism may be related to regulating the HSP70/PI3K/Akt signaling pathway and inhibiting the inflammatory reaction damage to the nerve cells of reperfusion.
RESUMO
OBJECTIVE:To investigate the effects of olmesartan medoxomil on cardiac function,plasma N-terminal pro-brain natriuretic peptide(NT-proBNP)and serum interleukin-23(IL-23)in patients with chronic heart failure(CHF),and to evaluation its safety. METHODS:A total of 40 CHF patients selected from Lianshui County People's Hospital of Jiangsu Province during Dec. 2014-May 2016 were divided into control group and observation group according to random number table,with 20 cases in each group. Control group was given Enalapril maleate tablets with initial dose of 5 mg,po,qd(increasing gradually after one week,limiting dose of 20 mg/d)+Metoprolol tartrate tablets 25 mg,po,bid+Isosorbide mononitrate tablets 40 mg,po,qd+Furose-mide tablets 20 mg,po,bid. Observation group was additionally given Olmesartan medoxomil tablets 20 mg,po,qd,on the basis of control group. Both groups received treatment for consecutive 8 weeks. Cardiac function indexes [LVEDD,LAD,IVST,LVP-WT,LVEF,early diastolic peak E filling velocity/late diastolic peak A filling velocity(E/A)],plasma NT-proBNP and serum IL-23 levels were observed in 2 groups before and after treatment. The incidence of ADR was recorded. RESULTS:Before treat-ment,there was no statistical significance in cardiac function indexes,plasma NT-proBNP or serum IL-23 levels between 2 groups (P>0.05).After treatment,LVEDD,LAD,plasma NT-proBNP and serum IL-23 levels of 2 groups were decreased significantly, while LVEF and E/A levels were increased significantly;the observation group was significantly better than control group,with sta-tistical significance(P<0.05). There was no statistical significance in IVST or LVPWT levels between 2 groups before and after treatment,and there was no statistical significance in the incidence of ADR between observation group(25.00%)and control group(20.00%)(P>0.05). CONCLUSIONS:Olmesartan medoxomil can decrease the levels of plasma NT-proBNP and serum IL-23 in CHF patients,and improve cardiac function with good safety.
RESUMO
Objective@#To evaluate the feasibility of combining simultaneous triple semicircular canal plugging (TSCP) and cochlear implantation (CI) to treat vertigo and hearing loss in advanced Meniere's disease(MD) patients, so as to provide an alternative surgical procedure for treating this disorder.@*Methods@#Data from seven patients, who were referred to our hospital and diagnosed with unilateral MD strictly meeting the criteria issued by Chinese Academy of Otolaryngology-Head and Neck Surgery Committee (2006), from Jan. 2015 to Jan. 2016, were retrospectively analyzed in this work. Seven patients, in whom the standardized conservative treatment had been given for at least one year and frequent vertigo still occurred, underwent simultaneous TSCP and CI under general anesthesia via mastoid approach. Postoperative follow-up time was more than six months. Vertigo control and auditory function were measured. Pure tone audiometry, speech perception scores, caloric test, head impulse test (HIT), and vestibular evoked myogenic potential (VEMP) were performed for evaluation of audiological and vestibular functions.@*Results@#All patients had bilateral severe sensorineural hearing loss preoperatively. One side hearing loss was due to MD and another side was due to reasons including sudden sensorineural hearing loss, mumps and other unknown reason. The total control rate of vertigo in seven MD patients was 100.0% in the six-month follow-up, with complete control rate of 85.7% (6/7) and substantial control rate of 14.3% (1/7). Improved hearing threshold and speech perception scores were observed in all study participants. Postoperative average aided hearing threshold was 32.5 dBHL, the average monosyllabic word score was 42.6% and speech perception scores of sentences tested in quiet was 52.3%. Tinnitus improved in five cases, and no significant change in two patients. Post-operatively, all patients suffered from temporary vertigo and balance disorders. Vertigo was disappeared in all patients within 3-5 days, while, an average recovery time of balance disorders was 19.7 days. Six months after treatment, loss of semicircular canal function by caloric test was found in the operation side of all patients and no change in cVEMP or oVEMP test was noted. All patients had no facial paralysis, cerebrospinal fluid leakage, and other complications.@*Conclusions@#A combined approach of TSCP and CI which could control vertigo effectively and improve hearing loss and tinnitus represents an effective and safe therapy for some advanced MD patients.
RESUMO
Objective To investigate the relationship between the expression level of HOTAIR and cellular radiosensitivity in esophageal squamous cell carcinoma (ESCC). Methods Four ESCC cell lines ( K150, K450, TE-1, and Eca109 ) were used in this study. Quantitative real-time polymerase chain reaction was applied to measure the expression level of HOTAIR in the above cell lines;colony-forming assay was applied to measure the survival fraction of different cells irradiated by different doses of X-ray. The t-test or analysis of variance was applied for analysis of differences. The correlation analysis was used by Pearson methods. Results The four cell lines all showed high expression levels of HOTAIR and radioresistance. Compared with the other three cell lines, Eca109 had a lower expression level of HOTAIR, a lower survival fraction at each radiation dose point, and significantly lower D0 and Dq . The mRNA expression level of HOTAIR and radiosensitivity were K150
RESUMO
Objective:To explore the clinical value of vestibular autorotation test (VAT) in the treatment for otogenic vertigo patients. Method:One hundred and twenty-nine definite otogenic vertigo patients were included. All patients underwent the VAT and caloric test (CT). The results were analyzed statistically. Result:In VAT examination, 89 (69.0%) cases were abnormal. In CT examination, 56 (43.4%) cases were abnormal. In the contrast test of VAT and CT, VAT results were abnormal in 47 (36.4%) patients and CT results were abnormal in 14 (10.9%) patients. The number of patients whose both VAT and CT results were abnormal was 42 (32.6%). The total number of patients with various abnormal results was 103 (79.8%). According to statistical analysis, the abnormal result rate of VAT was higher than that of CT. The abnormal result rate of both VAT and CT was higher than that of each single test. There was statistic significance in the difference (χ²=1.670, P<0.05). Conclusion:For otogenic vertigo patients, their abnormal result rate of VAT is higher than that of CT. VAT and CT can be mutually complementary. The combination of VAT and CT can help to understand the function of semicircular canal in the general and provide reference for the treatment of otogenic vertigo diseases.
RESUMO
Objective:To investigate frequency and position characteristics of the vestibular dysfunction in vestublar neuritis patients. Method:Colaric test (CT), head impulse test (HIT), cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential (oVEMP) were applied in 43 vestublar neuritis patients to assess their vestublar dysfunction. Superior vestublar nerve (S-VN), inferior vestibular nerve (I-VN), total vestibular nerve (T-VN) and each vestibular end organ incidence rate were calculated and statistically analyzed. Result:CT incidence rate (93.0%) was statistically higher than that of HIT (72.1%) (P<0.01). Total frequency incidence rate (72.1%) was statistically higher than that of low frequency (20.9%) (P<0.01). No high frequency only case was observed. The incidence rate of S-VN only, I-VN only and T-VN was 44.2%, 4.7% and 51.2% respectively. Among them, the incidence rate of I-VN was significantly lower than the others (P<0.01). The incidence rate of vestibular end organs was 17.4% (S-SCC), 44.2% (H-SCC), 20.9% (P-SCC), 39.5% (utricule) and 26.7% (saccule) respectively. The incidence rate of H-SCC was remarkably higher than the other semicircular canals (P<0.01). The difference between utricule and saccule was not statistically significant. Conclusion:The semicricular canal dysfunction in vestibular neuritis patients mainly involves total frequency of vestibular function, low frequency is more common than high frequency. Total vestibular nerve and single S-VN are mostly involved in vestibular neuritis.
RESUMO
Photodynamic therapy (PDT), because of its good targeting, minimal invasion, and safety, is becoming a very active area in cancer prevention and treatment, in which the photosensitizers have proved to be the core element for PDT. We developed a new HPLC method for analyzing porphyrin photosensitizers using Shiseido Capcell PAK C18 (150 mm x 4.6 mm, 5 µm) as the column at 30 °C, methanol-1% aqueous solution of acetic acid as the mobile phase in a flow rate of 1.0 mL · min(-1) in a gradient elution mode, and the detection wavelength at 380 nm. This method, showing good specificity, precision, accuracy and robusty via methodology validations, can be applied to the purity test and assay of porphyrin photosensitizers, and has played a key guide role in the R&D of the new porphyrin photosensitizer--sinoporphyrin sodium.
