ABSTRACT
Objective@#To investigate the efficiency and safety of hypofractionated radiotherapy (HFR) combined with chemotherapy using paclitaxel for the treatment of esophageal cancer (EC) patients with post-operative tracheoesophageal groove lymph node (TGLN) metastasis.@*Methods@#A total of fifty-three post-operative EC patients with TGLN metastasis were randomly divided into HFR group (n=25), receiving a radiation of 60 Gy/20 fractions, and conventional fractionated radiotherapy (CFR) group (n=28), receiving a radiation of 60 Gy/30 fractions combined with chemotherapy using paclitaxel with a dosage of 50 mg once per week through tossing a coin. the adverse events and the prognosis between two groups were compared.@*Results@#The incidence of radiation esophagitis and pneumonitis (grade 3-4) between the HFR group and CFR group showed no statistically significant difference (44.0%, 25.0%, P>0.05; 16.0%, 7.1%, P>0.05). No statistical difference was noticed in the efficiency between the HFR group and the CFR group (P>0.05). The efficiency in patients with lymph node metastasis at diameters ≤2 cm was significantly higher than that with lymph node metastasis at diameters >2 cm (P<0.05). The median overall survival (OS) of the HFR group showed a significant increase compared with that of the CRF group [24.2 months (95%CI 16.2-32.1 months) vs. 11.8 months (95%CI 9.2-14.4 months)] (χ2=5.063, P<0.05). Both univariate and multivariate analysis indicated that TGLN diameter (P<0.05) and fractioned types (P<0.05) were factors that affected the prognosis.@*Conclusions@#The combination of HFR and chemotherapy contributed to the improvement of prognosis in EC patients with TGLN metastasis and there was no obvious increase in the adverse events.@*Trial registration@#Chinese clinical trial registry, ChiCTR1800016848
ABSTRACT
OBJECTIVE:To study the chemical constituents of the flower of Zang Epipremnum aureum. METHODS:The con-stituents of ethyl acetate extract of the flower of E. aureum were separated and purified with varied chromatographic techniques, and the structures were identified based on spectral data and chemical properties. RESULTS:Ten compounds were isolated from eth-yl acetate extract of the flower of E. aureum,they were identified as rutamontine(1),edgeworoside C(2),edgeworin(3),tiliro-side (4),helichrysoside (5),kaempferol (6),2,4-dihydroxypheny-2-hydroxy-4-metho-xybenzyl-ketone (7),ethyl caffeate (8), phthalic acid bis-(2-ethyl-hexyl) ester (9) and noreugenin (10). CONCLUSIONS:Compound 7 is firstly isolated from natural source,compounds 5,8 and 9 is firstly isolated from the family Thymelaeaceae,compound 6 is firstly isolated from Edgeworthia and compound 2 and 10 are firstly isolated from the flowers of E. aureum. The study lays certain foundation for the quality evalua-tion of E. aureum.
ABSTRACT
Objective To investigate the clinical effect of longxuejie capsule in combination with tinidazole in the treatment of chronic cervicitis and its effects on levels of immunoglobulin.Methods 90 cases in our hospital from January 2013 to June 2014, with chronic cervicitis meeting the inclusion critera were randomly divided into 2 groups by method of stratified randomization equally.Control group (n=45) was treated with tinidazole and conventional treatments, while observation group ( n =45 ) was treated with tinidazole and longxuejie capsule.Then, the curative efficacy, scale of symptoms and levels of immunoglobulin were observed and compared.Results The therapeutic efficiency ratio of observation group was 95.6%, which was significantly higher than that of control group ( 80.0%, P<0.05 ).After the treatment, in comparison with the control group, scale of cervical secretion and severity of cervical lesion was statistically lower respectively than observation group ( P<0.05 ).As to immunological function, concentrations of IgG, IgM, IgA in observation group were statistically higher than that in control group after the treatment (P<0.05).The control group and observation group respectively in 2 cases and 3 cases of abdominal pain, alleviated by themselves without treatment.Conclusion longxuejie capsule combined with tinidazole is effective and reliable for patients with chronic cervicitis, which significantly improves symptoms and elevates levels of immunoglobulin.
