ABSTRACT

Objective:To identify objective markers between the Parkinson variant of multiple system atrophy (MSA-P) and Parkinson′s disease (PD).Methods:Retrospective analysis was performed on 10 patients with MSA-P, 15 patients with PD, and 15 healthy control group during the period from August 2016 to February 2019 in Baoshan Branch of Shanghai First People′s Hospital.We combined the novel tract based spatial statistics (TBSS) and region of interest (ROI) analyses for the first time to investigate three groups with diffusion tensor imaging. By TBSS, we performed pairwise comparisons of mean diffusivity and fractional anisotropy (FA) maps. The clusters with significant differences between MSA-P and PD were used as ROIs for further analyses.Results:FA values in the left anterior thalamic radiation(ATR) (ROI values were 0.371(0.287-0.535), 0.472(0.390-0.594), 0.473(0.388-0.555); P values were 0.008, 0.008) and left superior longitudinal fasciculus (SLF)(ROI values were 0.397(0.291-0.469), 0.456(0.338-0.560), 0.473(0.427-0.530); P values were 0.013,<0.001) were significantly decreased in MSA-P compared with PD or controls, and significantly correlated with clinical data(( r =-0.807, P =0.005),( r =-0.455, P =0.022)). Conclusion:Our findings indicate the abnormalities of left ATR and left SLF as specific biomarkers for differential diagnosis.

ABSTRACT

Objective:To construct and confirm a predictive model for the risks of cardiovascular diseases (CVD) with metabolic syndrome (MS) and its factors in Xinjiang Kazakh population.Methods:A total of 2 286 Kazakh individuals were followed for 5 years from 2010 to 2012 as baseline survey. They were recruited in Xinyuan county, Yili city, Xinjiang. CVD cases were identified via medical records of the local hospitals in 2013, 2016 and 2017, respectively. Factor analysis was performed on 706 MS patients at baseline, and main factors, age, and sex were extracted from 18 medical examination indexs to construct a predictive model of CVD risk. After excluding the subjects with CVD at baseline and incomplete data, 2007 were used as internal validation, and 219 Kazakhs in Halabra Township were used as external validation. Logistic regression discriminations were used for internal validation and external validation, as well as to calculate the probability of CVD for each participant and receiver operating characteristic curves.Results:The prevalence of MS in Kazakh was 30.88%. Seven main factors were extracted from the Kazakh MS population, namely obesity factor, blood lipid and blood glucose factor, liver function factor, blood lipid factor, renal metabolic factor, blood pressure factor, and liver enzyme factor. The area under the curve (AUC) for predicting CVD in the internal validation was 0.773 (95% CI 0.754-0.792). In the external validation, the AUC for predicting CVD was 0.858 (95% CI 0.805-0.901). Conclusions:The CVD risk prediction model constructed by 7 main factors extracted from Kazakh MS patients has high validation efficiency and can be used for risk assessment of CVD in Xinjiang Kazakh population.

ABSTRACT

Objective:To investigate the clinical value of serum miR-208a in early differential diagnosis of acute coronary syndrome(ACS).Methods:One hundred ACS patients admitted to our department from January 2016 to January 2018 were randomly divided into the non-ST elevation myocardial infarction(NSTEMI)group(n=50)and the unstable angina(UA)group(n=50). Fifty healthy people during the same period were included as the control group(control). Serum levels of miR-208a, cardiac troponin-T(cTnT)and creatine kinase MB isoenzyme(CK-MB)were detected immediately, 4 h, 12 h and 24 h after admission and compared among the three groups of NSTEMI, UA and control.Receiver operating characteristic(ROC)curve was used to analyze the early diagnostic value of above serum indexes in NSTEMI and UA group, and the correlations of miR-208a level with cTnT and CK-MB were analyzed.Results:Serum miR-208a and cTnT levels had significant differences( P<0.05), while serum CK-MB level had no significant difference( P>0.05)among the NSTEMI and UA groups immediately after admission and the control group in the fasting state.There were significant differences in serum miR-208a, cTnT and CK-MB levels between NSTEMI group and UA group at different time points( P<0.05). After further multiple comparisons, the results showed that serum miR-208a and cTnT levels had statistical differences( P<0.05)and serum CK-MB level had no difference( P>0.05)between the NSTEMI group and the UA group immediately after admission.The above three biochemical indexes showed statistically significant differences between the NSTEMI group and the UA group at 4 h, 12 h and 24 h after admission( P<0.05). ROC curve analysis showed that miR-208a had a high diagnostic value in ACS(AUC>0.9, P=0.004), and the best diagnostic cut-off point was 9.278.The cTnT had a medium diagnostic value in ACS(0.7<AUC<0.9, P=0.013), and the diagnostic cut-off point was 5.147 μg/L.CK-MB had a low diagnostic value in ACS(0.5<AUC<0.7, P=0.031), and the diagnostic cut-off point was 82.716 u/l.Serum miR-208a level was positively correlated with cTnT level in ACS patients( P<0.05), and there was no correlation between serum miR-208a level and CK-MB level( P>0.05). Conclusions:Serum miR-208a has a higher value in early diagnosis of ACS than cTnT and CK-MB, and it has a better differentiation ability of NSTEMI than UA.

ABSTRACT

Objective:To systematically evaluate the clinical efficacy of laparoscopic common bile duct exploration (LCBDE) combined with endoscopic nasobiliary drainage (ENBD) versus T-tube drainage in the treatment of choledocholithiasis.Methods:Databases including PubMed(Medline), Embase, the Cochrane Library, Web of Science, Wanfang, CNKI and CBM were searched for literatures from January 1960 to May 2019 with the key words including "胆总管结石病,胆总管结石; T管引流, T管;鼻胆管引流,经内镜鼻胆管引流术, ENBD管, ENBD引流; cholelithiasis, common bile duct stone, jaundice, obstructive, Jaundice, gallstone; T-tube drainage, T-tube, t-tube, biliary tract drainge, drainge tube; endoscopic nasobiliary drainage, nasobiliary drainage, nasobiliary tube, endoscopic drainage tubes, endoscopic drainage tube, endoscopic retrograde biliary drainage" . The randomized controlled trials (RCTs) and high quality non-randomized controlled trials (NRCTs) on comparing ENBD and T-tube drainage during laparoscopic choledocholithotomy were included.Patients who received LCBDE combined with preoperative or intraoperative ENBD were allocated into ENBD group, and patients who received LCBDE combined with postoperative T-tube drainage were allocated into T-tube drainage group. Reported outcomes: operation time, volume of intraoperative blood loss, duration of postoperative hospital stay, time to drainage tube removal, time to postoperative gastrointestinal function recovery, treatment expenses, rate of surgical failure, incidence of postoperative biliary fistula, incidence of postoperative incisional infection, incidence of postoperative residual stones, incidence of postoperative pancreatitis, incidence of postoperative hyperamylasemia, incidence of postoperative bile peritonitis. Count data were represented as odds ratio ( OR) and 95% confidence interval (95% CI). Measurement data were represented as mean difference ( MD) and 95% CI. The I2 and Q tests were used to analyze literature heterogeneity. I2≤50% or P>0.10 indicated no significant heterogeneity, so fixed effects model was used for Meta analysis. I2>50% and P≤0.10 indicated a significant heterogeneity, so random effects model was used for Meta analysis. When analyzing the measurement data, subgroup analysis of individual indicators was performed if there were more than 4 RCTs included, and NRCTs were analyzed for supplement if there were no more than 4 RCTs included. When analyzing the count data, RCTs and NRCTs were combined for analysis. Funnel plots were used to test potential publication bias if there were more than or equal to 10 studies included, while no test was needed if there were less than 10 studies included. Results:(1) Document retrival: 26 literatures meeting the standards were included, including 9 RCTs and 17 NRCTs (4 semi-randomized studies and 13 case-control studies). There were 2 098 patients, including 1 114 patients in the ENBD group and 984 patients in the T-tube drainage group. (2) Results of Meta analysis. ① Duration of postoperative hospital stay: there was a significant difference in the duration of postoperative hospital stay between the ENBD group and T-tube drainage group ( MD=-6.53, 95% CI: -8.64 to -4.43, P<0.05). Further analysis of 9 RCTs showed significant differences in the duration of postoperative hospital stay between patients without acute complications of choledocholithiasis in the ENBD group and those in the T-tube drainage group, between patients with acute complications of choledocholithiasis in the ENBD group and T-tube drainage group, respectively ( MD=-5.88, -8.77, 95% CI: -8.32 to -3.45, -12.39 to -5.15, P<0.05). ② Time to drainage tube removal: for the RCTs, there was a significant difference in the time to drainage tube removal between the ENBD group and T-tube drainage group ( MD=-46.01, 95% CI: -83.64 to -8.37, P<0.05). For the NRCTs, there was a significant difference in the time to drainage tube removal between the ENBD group and T-tube drainage group ( MD=-24.05, 95% CI: -32.93 to -15.18, P<0.05). ③ Time to postoperative gastrointestinal function recovery: for the RCTs, there was a significant difference in the time to postoperative gastrointestinal function recovery between the ENBD group and T-tube drainage group ( MD=17.80, 95% CI: -31.11 to -4.48, P<0.05). For the NRCTs, there was a significant difference in the time to drainage tube removal between the ENBD group and T-tube drainage group ( MD=-5.64, 95% CI: -10.16 to -1.12, P<0.05). ④ Incidence of postoperative biliary fistula: there was a significant difference in the incidence of postoperative biliary fistula between the ENBD group and T-tube drainage group ( OR=0.50, 95% CI: 0.28-0.89, P<0.05). ⑤ Incidence of postoperative incisional infection: there was a significant difference in the incidence of postoperative incisional infection between the ENBD group and T-tube drainage group ( OR=0.35, 95% CI: 0.17-0.73, P<0.05). (3) Analysis of publication bias. The incidence of postoperative biliary fistula in the two groups was analyzed by funnel plot based on the 15 studies. The bilateral symmetry was presented in the funnel plot for incidence of postoperative biliary fistula, suggesting that publication bias had little influence on results of Meta analysis. Conclusion:For patients with choledocholithiasis that endoscopic lithotomy is not feasible, LCBDE combined with ENBD can significantly shorten duration of postoperative hospital stay, time to drainage tube removal, postoperative gastrointestinal function recovery time, reduce the incidence of postoperative biliary fistula and incisional infection compared with LCBDE combined with T-tube drainage.

ABSTRACT

Objective@#To compare metabolic syndrome(MS)with Framingham risk score as predictors of cardiovascular disease(CVD)among Kazakhs population.@*Methods@#The participants were the residents who had been followed up for more than 5 years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting development of CVD using Cox regression and receiver operating characteristic curve.@*Results@#The incidence of CVD was 13.87%. The incidence of CVD was higher in the MS group than it in the non-MS group(21.59% vs 11.10%, P<0.001). The area under the receiver operating characteristic(ROC)curve of MS risk score was significantly larger than that of MS classification(0.727 vs 0.585, P<0.001); the area under the curve of MS risk score was close to that of Framingham risk score(0.732 vs 0.727, P=0.673). The association between CVD and each quintile of MS risk score was more significant than that between Framingham risk score and CVD under the same exposed condition(4.61, 9.33, 14.15, 22.29 vs 3.69, 6.36, 8.47, 16.99).@*Conclusion@#MS risk score that included age may be a better predictor of CVD among Kazakhs population.

ABSTRACT

Objective To investigate the correlation between myeloperoxidase(MPO)levels and adverse cardiac events in patients undergoing coronary stent implantation.Methods A total of 76 patients undergoing coronary stent implantation from January 2015 to June 2016 in the cardiac surgery department of our hospital were enrolled in this study.Serum levels of MPO,high sensitivity C-reactive protein(hs-CRP),and interleukin 6 (IL-6)were detected by enzyme-linked immunosorbent assays(ELISA).After a one-year follow-up,the receiver operating characteristic(ROC)curve was used to determine the predictive value of the difference in MPO before and after the operation(△MPO)on the long-term prognosis of patients after coronary stent implantation.The correlations of △MPO with the traditional risk factors for coronary heart disease and adverse cardiac events were analyzed using multi factor Logistic regression analysis.Results Serum levels of MPO,hs-CRP and IL 6 increased in patients after coronary stent implantation,compared with those before treatment (P < 0.05).The results of ROC curve analysis showed that the area under the curve(AUC)value of serum △MPO was 0.786,the 95 % confidence interval was 0.471~ 1.000 and the predictive value of serum △MPO for adverse cardiac events was significant(P <0.05).There was a significant correlation between △MPO and age,and the incidence of adverse cardiac events increased with increased △MPO levels.Logistic regression analysis showed that serum △MPO levels could preliminarily diagnose the cardiovascular risk after coronary stent implantation and independently predict the occurrence of adverse cardiac events.Conclusions MPO levels in peripheral blood are notably elevated in patients after coronary stent implantation when compared with pre-treatment levels.Serum △MPO levels can preliminarily diagnose adverse cardiac events after coronary stent implantation and can be used as a marker to predict adverse cardiac events.

ABSTRACT

Objective To investigate the relationship between serum markers β amyloid (Aβ), tau and thyroid hormone levels and post-stroke cognitive impairment (PSCI) in the acute phase of cerebral infarction. Methods A total of 214 patients with acute cerebral infarction were enrolled. The baseline data and serological indicators were collected and the cognitive function of patients was evaluated. All patients were divided into cognitive impairment group and normal group based on follow-up results. The differences of Aβ1-42, tau protein and thyroxine levels between the two groups and their relationship with disease progression were analyzed. The Cox regression analysis and ROC curve were used to compare the above parameters to predict the development of PSCI. Results The total protein level of Tau (210.6 ±98.9 pg/mL) was higher and Aβ1-42 (426.1 ±123.5 pg/mL) and triiodothyronine (T3) (1.43 ±0.57 nmol/L), free thyroxine (FT4) (13.15±2.23 pmol/L) was significantly lower in the cognitive impairment group than in the normal group (P<0.05). Tau protein (r=-0.457), Aβ1-42 (r=0.348), T3 (r=0.211), and FT4 (r=0.306) were all associated with disease progression (P<0.05). Cox regression analysis showed that Aβ1-42 and T3 were important influencing factors in the occurrence of PSCI. The area under the curve of Aβ1-42 combined with T3 was 0.841. The specificity and the sensitivity were 74.8% and 85.3%, respectively, with a diagnostic cutoff value of 0.572. Conclusion Aβ1-42 and T3 levels in the acute phase of cerebral infarction may predict the progression of PSCI.

ABSTRACT

Objective Meningiomas in the trigone of the lateral ventricle are characterized by deep location and low inci-dence. A few studies have been done on its treatment at home and abroad. This study was to explore the access,techniques,and clini-cal effect of microsurgery for lateral ventricular trigone meningiomas (LVTM). Methods We retrospectively analyzed the clinical data about 36 cases of LVTM treated by microsurgery in our hospital from December 2011 to December 2015. The operation involved lumbar cistern tube drainage, intraoperative drainage of cerebrospinal fluid, a unilateral parieto-occipital U-shaped cut, approach through the interparietal fissure,a sagittal incision about 3 cm long at the interparietal fissure for exposure and resection of the tumor. We followed up the patients for a mean of 17 months postoperatively and analyzed the results and complications. Results Simpson grade I removal of the tumors was achieved in all the 36 cases. Postoperative complications included homonymous hemianopia in 4 cases, central nervous system infections in 3,secondary epilepsy in 2,subcutaneous hydrops in 2,and intratumoral hemorrhage in 1 (which necessitated a second operation). Extended temporal horn of the right lateral ventricle occurred at 32 months after surgery,which was treated by fistulation. Homonymous hemianopia was improved in 2 of the 4 ca-ses. All the patients were capable of daily life activities and none experienced recurrence. Conclusion Sufficient preoperative evalu-ation of the tumor characteristics,rational selection of surgical approach,and expert operation techniques are the key factors for the mi-crosurgical treatment of meningiomas in the trigone of the lateral ventricle.

ABSTRACT

Objective To investigate the expression of microsomal glutathione S-transferase 1 ( MGST1) in hepa-tocellular carcinoma ( HCC) and its significance in the development of HCC. Methods Western blot was used to measure MGST1 expression in human hepatocellular carcinoma and adjacent tissues and HCC cell lines. Further-more, shRNA targeting MGST1 was constructed and transected into MHCC97H and HCCLM3 cells to deplete MGST1 expression. MGST1 was over-expressed in SK-Hep-1 cells using pCDH lentivirus system. Cell proliferation and migration were analyzed by colony formation and Transwell migration assay, respectively. The subcutaneous xenograft model of MHCC97H cells in nude mice was established to check tumor development and mouse survival.Results MGST1 was higher in 71% (17/24) of HCC tissues compared with their adjacent liver tissues. Cell proliferation and migration were significantly decreased by MGST1 knockdown, while they were increased by MGST1 overexpression. Furthermore, mice implanted with shMGST1 MHCC97H cells exhibited retarded tumor formation and tumor progression compared with control group. Conclusions MGST1 overexpression promotes hepatocellular carcinoma development and this molecule targeted for HCC treatment.

ABSTRACT

Objective To investigate the effect of ultrasound elastography combined with serum carbohydrate antigen 15-3(CA15-3 C), C keratin 19 fragment antigen 21-1(CYFRA21-1)and prostate specific antigen (PSA) levels detection on the sensitivity and accuracy of breast cancer diagnosis. Methods Sixty cases of breast cancer from December 2015 to January 2017 were selected as study group, and all cases were diagnosed as breast cancer by pathological examination.They were divided into groups according to the TNM classification criteria of breast cancer, stageⅠ22 cases, stageⅡ17 cases, stage Ⅲ14 cases, stageⅣ7 cases.Fifty-three cases of benign breast diseases were selected as control group. The levels of serum CA15-3, CYFRA21-1 and PSA were compared among two groups and the study group at different stages. The correlations between serums CA15-3, CYFRA21-1 and PSA expression level and breast cancer staging were analyzed. The results of pathological examination were regarded as "gold standard". Serum CA15-3, CYFRA21-1, PSA levels, single detection of ultrasound elastography and combined detection of breast cancer results were compared. Results The levels of serum CA15-3, CYFRA21-1 and PSA in study group were higher than those in control group:(37.98 ± 4.71)kU/L vs.(8.58 ± 3.04) kU/L,(5.41 ± 3.24)μg/L vs.(1.42 ± 0.47)μg/L,(0.39 ± 0.11)μg/L vs. (0.16 ± 0.04) μg/L, and there were significant differences (P<0.01). The levels of serum CA15-3, CYFRA21-1 and PSA in patients with stageⅢandⅣof breast cancer were higher than those of patients with stageⅠandⅡof breast cancer,and there were significant difference(P<0.01).Spearman correlation analysis showed that serum CA15-3, CYFRA21-1 expression levels and breast cancer staging was positively correlated (P < 0.05). There was a negative correlation between serum PSA expression and breast cancer staging(P<0.05).The sensitivity 98.33%(59/60), specificity 96.23%(51/53)and accuracy rate 97.35%(110/113) of breast cancer detected by serum CA15-3, CYFRA21-1, PSA levels and ultrasonic elastography was higher than that of single dectction, and the difference was statistically significant (P < 0.05). Conclusions The levels of serum CA15-3, CYFRA21-1 and PSA are closely related to the occurrence and progression of breast cancer.The combination of serum CA15-3, CYFRA21-1 and PSA levels with ultrasonic elastography can improve the specificity, sensitivity and accuracy of diagnosis of breast cancer.

ABSTRACT

Objective Toinvestigatetheapplicativevalueof3D-DSAandheadMRIorCTfusion technology for guiding the individualized treatment of intracranial arteriovenous malformation (AVM ). Methods Twenty-onepatientswithAVMdiagnosedwithDSAattheDepartmentofNeurosurgery,Nanjing General Hospital of Nanjing Military Command from January 2015 to May 2015 were analyzed retrospectively. All patients performed DSA,MRI,and CT scan respectively before procedure,and they also performed 3 D-DSA and MRI or CT fusion. Of the 21 patients,15 performed MRI and 3D-DSA fusion,6 performed CT and 3D-DSA fusion. According to the image fusion results of the patients,the individualized treatment regimens were further developed,including microsurgical resection,endovascular embolization,and stereotactic radiotherapy (alone or combined treatment). The patients were followed up and observed for 2 to 6 months after procedure.Results Fromthe3D-DSAwithheadMRIorCTfusionimagesofthepatientsbeforetheprocedure not only could observe the vascular architecture of AVM,the relationship between the niduses and the surrounding nerve structures,but also could precisely locate the positions of AVM with small aneurysms or tiny AVMs. According to the results of image fusion,17 patients with AVM were treated with microsurgical resection,2 were treated with interventional embolization and stereotactic radiotherapy,and 2 were treated with stereotactic radiotherapy only. Of the 17 patients with AVM underwent microsurgical resection, none experienced intracranial rebleeding during the follow-up period. The last Glasgow outcome scale (GOS)score was 5 in 13 cases,and 4 in 4 cases. One patient with AVM underwent combined stereotactic radiotherapy had intracranial rebleeding during the follow-up period,and their last GOS score was 4. The other remaining 3 patients did not have new neurological deficits or rebleeding during the follow-up period,and theirGOSscorewas5.Conclusions 3D-DSA,headMRI,andCTfusiontechnologyarenovel, the operative method is simple,and the fusion image is accurate. They can effectively develop the individualized treatment regimens for patients with AVM.

ABSTRACT

Objective To investigate the preoperative and intraoperative assessed values of the color-coded digital subtraction angiography (DSA ) for intracranial arteriovenous malformation (AVM). Methods Fifteen patients with AVM performed preoperative routine whole brain DSA were analyzed retrospectively,and the iFlow software was used to perform color-coded DSA of image post-processing. A comprehensive analysis such as the range of lesions,vascular architecture and hemodynamics of AVM was conducted on the two-dimensional DSA images and color-coded DSA. Results Of the 15 patients with AVM,9 were small-sized (including 4 nidi showed diffuse type),3 were medium-sized,and 3 were large-sized;8 patients had single feeding artery,and 7 had multiple feeding arteries;11 had single draining vein,and 4 had multiple draining veins. When showing the size of AVM nidus,particularly diffuse type nidus, the color-coded DSA was clearer than the two-dimensional image. The color-coded DSA could visually display the traveling of the superficial and deep draining veins,at the same time,the primary and secondary draining veins could be identified according to the size of the area under the curve and the full width at half maximum,and intuitively reflected the complete cycle of cerebral blood flow. Conclusion The color-coded DSA can quickly and accurately depict the range of AVM,angioarchitecture features and intraoperative hemodynamic changes.

ABSTRACT

The circulating tumor cells (CTCs) are derived from primary or metastatic tumor lesions and can be detected in the peripheral blood. With certain specific features, CTCs can,to certain extent, reflect the progression and invasiveness of tumors. Detection of CTCs may provide a powerful and noninvasive approach for diagnosing neoplastic disease, identifying drug sensitivity, and enabling real-time treatment monitoring and prognosis prediction. Improvements in cell isolation and molecular identification will enable a broad range of clinical applications.

ABSTRACT

To assess the clinical effect and safety of Chinese traditional medicine injection combined with radiotherapy for esophageal cancer. The relative randomized controlled trials (RCTs) of Chinese medical injections (CMI) combined with radiotherapy as well as simple radiotherapy for esophageal cancer were searched from PubMed, Cochrane Library, EMBASE, Chinese Biomedical Literature Database(CBM), China National Knowledge Infrastructure (CNKI), Wanfang Database and VIP Database as at September 2014. Two researchers completed the data extraction and quality evaluation independently. The data were analyzed by GeMTC 0.14.3 and Stata 12. 0 software. Finally, 43 RCTs involving 3 289 patients were finally included. The star network was constructed by different comparison groups. The results of network meta-analysis showed that the seven CMIs combined with radiotherapy was superior to simple radiotherapy in the treatment of esophageal cancer in efficacy, quality of life, and reduction in the incidence of nausea and leucopenia, but with no significant difference among the seven CMIs. Probability ranking result showed a great possibility for Shenqi Fuzheng and astragalus polysaccharide injections in improving the overall response rate and quality of life, which were followed by cinobufagin and kangai injections. However, only one study was included for Shenqi Fuzheng and astragalus polysaccharide injections. Therefore, cinobufagin or kangai injections were preferred in improving the overall response rate and quality of life. Aidi or compound sophora injections were better than other CMIs in reducing? the incidences of nausea (III-IV) and leukopenia. More RCTs of Shenqi Fuzheng and astragalus polysaccharide injections combined with radiotherapy for patients with esophageal cancer were expected in the future to confirm our results. Moreover, study findings will be reported, particularly for the adverse events in radiotherapy for esophageal cancer.

ABSTRACT

Long non-coding RNAs(LncRNA)may play a key role in tumorigenesis by regulating gene expression and intervening transcription. Recent studies have demonstrated that a series of patterns including protein modification,chromosomal reconstruction,regulation of target gene expression,transcription intervention,epigenetic modification,and natural antisense transcript are involved in this process. This article reviews recent research advances in this aspect with an attempt to better understand the role of LncRNA in tumorigenesis.

ABSTRACT

A high-performance liquid chromatography method of pre-column derivatization with 1-phenyl-3-methyl-5 -pyrazolone (PMP) has been established for determination of 6 kinds of monosaccharides simultaneously. A special Agilent HC-C18 column (4. 6 mm x 250 mm, 5 microm), optimized for the separation of PMP derivatives, was used at ambient temperature of 40 degrees C. The PMP derivatives elution was performed with a mixture of 0.1 mol x L(-1) phosphate buffer (pH 6. 8) and acetonitrile in a ratio of 84: 16 at a flow rate of 1 mL x min(-1), and UV absorbance of the effluent was monitored at 245 nm. The results showed that the polysaccharides from exopleura of Ginkgo biloba were acidic heteropolysaccharides mainly containing mannose, rhamnose, D-galacturonic acid, glucose, galactose, arabinose, with the molar ratio of 0.032: 0.14: 0.296: 0.403:0.106: 0.046.
