ABSTRACT
A simple,fast and highly sensitive fluorescence analysis method for detection of mercury ion was developed based on N-methyl-mesoporphyrin IX (NMM)/G-quadruplex DNA system and specific T-Hg-T mismatches.In this strategy,a large number of thymine was introduced into guanine-rich oigonucleotides which could form G-quadruplex.In the presence of Hg2+,guanine-rich oigonucleotides and complementary strand could form double-stranded DNA molecule by specific T-Hg-T mismatch pair,leading to destruction of G-quadruplex DNA structure.In the absence of Hg2+,guanine-rich oigonucleotides spontaneously formed G-quadruplex DNA structure that could bound NMM to generate intense fluorescence.Based on the above facts,a sensitive fluorescence biosensor for determination of Hg2+ was fabricated.And the optimal conditions for Hg2+ determination were as follows:buffer solution pH of 6.7,20 mmol/L KCl and 2.5 μmol/L NMM in buffer and incubation for 2 h.Under the optimal conditions,the fluorescence intensity signal change (F0-F) and the Hg2+ concentration exhibited a linear correlation within 50 nmol/L to 1000 nmol/L range with a low detection limit of 22.8 nmol/L (3σ).The biosensor exhibited good selectivity toward common metal ions.The developed method was successfully employed to detect Hg2+ in tap water with recovery of 106.1％-107.8％.
ABSTRACT
This study was aimed to analyze the application of non-pharmacotherapy in treating cervical radiculopathy (CR) in real-world,and to provide clinical reference for CR non-pharmacotherapy.The clinical real-world data of CR was extracted by using information sharing system of traditional Chinese medicine (TCM) and clinical research.Six hundred and twenty-eight inpatients and outpatients with CR were enrolled from December 2012 to July 2014 in the information system database of Wangjing Hospital.Basic characteristics of the non-pharmacotherapy groups were analyzed by statistical description method.The node degree and mutual information value were recorded for non-pharmacotherapy application of all patients by using liquorice software.Complex network diagrams were generated.The results showed that 47％ of CR patients received non-pharmacotherapy (294/628),including 67 males and 227 females.The average age of patients was 49 years old,and the prevalence of the disease was the highest from 45 to 65 years old.In all patients,the usage of manipulation and cervical traction was higher,and the combination of manipulation and acupuncture was the most.Within outpatients,the proportion of cervical traction was higher,and the combination of manipulation and acupuncture was the most frequently.Within inpatients,the proportion of manipulation and cervical traction was higher,and the combination of comprehensive physical therapy and exercise therapy was the most frequently.It was concluded that non-pharmacotherapy has been commonly used in clinical treatment of CR.Cervical traction and manipulation was the widest applications.The combination treatment was in wide application.Future studies should increase the sample size of CR patients from different regions,and enhance gradually the level of evidence of clinical research for non-pharmacotherapy treating CR.
ABSTRACT
Objective:To evaluate the clinical value and the prognostic factors of postoperative radiotherapy in type B3 thymoma pa-tients. Methods:A total of 159 patients with thymoma were treated by surgery and postoperative radiotherapy. According to Masaoka staging system, 12, 33, 62, and 52 patients had stageⅠ,Ⅱ,Ⅲ, andⅣlesions, respectively. Myasthenia gravis existed in 38 patients. Altogether 58 patients underwent chemotherapy. Overall survival, disease-free survival, and local control rates were calculated by Ka-plan-Meier method. Prognostic factors were analyzed by Cox regression model. Results:With a median follow-up of 52 months (8-125 months), the overall 5-year survival rate was 81.6%. The 5-year progression-free survival rate was 76.2%. The 5-year local control rate was 82.6%. The recurrence rate was 32.6%, and the metastatic rate was 9.3%. In the univariate analysis, tumor size, Masaoka stage, re-section margin, radiotherapy, and chemotherapy were significantly associated with 5-year overall survival and progression-free surviv-al (P<0.05). In the multivariate analysis, Masaoka stage, resection margin, and radiotherapy were independent prognostic factors of 5-year progression-free survival (P<0.05). Radiotherapy could improve the regional control rate and the overall survival of patients in Ma-saoka stagesⅢ-Ⅳ. Conclusion:The major failure mode for type B3 thymoma is the recurrence of pleure. Radiotherapy can improve the regional control rate and the overall survival of patients in advanced stages. Masaoka staging, surgical margin, and radiotherapy are the independent prognostic factors for type B3 thymoma treated by postoperative radiotherapy.
ABSTRACT
Chemotherapy is one of the main treatment methods in malignant tumor.Tumor multidrug resistance (MDR) is one of the important reasons for the failure of chemotherapy.It makes some progress in reversing tumor MDR,such as chemical drug,traditional Chinese medicine,immunotherapy,gene therapy,nanoparticles drug system and so on.But it takes more effort to develop medicine of less adverse reactions,better pharmacodynamic and application to clinic widely.
ABSTRACT
OBJECTIVE:To observe the effects of Vitamin B6 on efficacy and related indexes of patients with peripartum car-diomyopathy(PPCM). METHODS:64 PPCM patients were randomly divided into control group(32 cases)and observation group (32 cases). Control group received diuretic drugs,angiotensin converting enzyme inhibitors or angiotensin Ⅱ receptor antagonist,β-blockers,digitalis,low molecular weight heparin and other conventional treatment. Observation group additionally received Vita-min B6 tablet 50 mg,orally,twice a day. They treated for 2 weeks. Clinical efficacy,serum prolactin(PRL),brain natriuretic pep-tide (BNP),left ventricular end-diastolic diameter (LVEDD) before and after treatment,milk back rate and the incidence of ad-verse reactions in 2 groups were observed. RESULTS:There was no significant difference in the total effective rate in 2 groups (P>0.05). Before treatment,there were no significant differences in PRL,BNP and LVEDD in 2 groups (P>0.05). After treat-ment,PRL,BNP and LVEDD in 2 groups were significantly lower than before,and observation group were lower than control group,with statistical significances (P<0.05). And the milk back rate in observation group was significantly higher than control group,with statistical significance(P<0.05). There were no obvious severe adverse reactions during treatment. CONCLUSIONS:Based on conventional treatment,Vitamin B6 shows similar efficacy and safety with conventional treatment in the treatment of PPCM,though it is superior to conventional treatment in terms of decreasing PRL level,it has high milk back rate.
ABSTRACT
Traditional chemotherapy mostly caused the proliferative cancer cells'deoxyribonucleic acid damaged and suspended copy.It is purposed to kill cancer cells as far as possible.So we adopted chemotherapeutics' human maximum tolerated dose clinically.Recent findings indicate that some chemotherapy drugs such as paclitaxel are applied under way in the low dose and high frequency could inhibit tumor angiogenesis.
