RESUMO
Objective:To investigate the effects of nedaplatin combined with docetaxel on serum tumor markers and T lymphocyte subsets in patients with epithelial ovarian cancer.Methods:Ninety-two patients with epithelial ovarian cancer who received treatment from March 2016 to December 2017 were included in this study. They were randomly assigned to undergo nedaplatin combined with docetaxel (observation group, n = 46) or cisplatin combined with paclitaxel (control group, n = 46). Both groups received two 21-day courses of treatment. Serum tumor marker level, T lymphocyte subset level, clinical efficacy, incidence of adverse reactions, and 2-year survival rate were compared between the two groups. Results:After treatment, serum cancer antigen 125 (CA125), cancer antigen 199 (CA199), and carcinoembryonic antigen (CEA) levels were (45.84 ± 22.46) U/mL, (35.13 ± 15.03) U/mL, (16.21 ± 3.20) U/mL, respectively in the control group and they were (28.33 ± 20.11) U/mL, (14.82 ± 10.11) U/mL, (5.16 ± 1.33) U/mL, respectively in the observation group. After treatment, CA125, CA199, and CEA levels in each group were significantly decreased compared with before treatment. After treatment, CA125, CA199, and CEA levels were significantly lower in the observation group than in the control group ( t = 3.94, 7.61, 21.63, all P < 0.05). After treatment, the numbers of CD3 +, CD4 +, CD8 + cells in the control group were (16.22 ± 3.12)%, (15.20 ± 1.46)%, (29.21 ± 5.17)%, respectively, and they were (31.22 ± 4.11)%, (24.99 ± 1.71)%, (24.25 ± 4.45)% respectively in the observation group. After treatment, the numbers of CD3 + and CD4 + cells in the observation group were significantly higher than those in the control group ( t = 19.72, 29.53, both P < 0.05). After treatment, the number of CD8 + cells in the observation group was significantly lower than that in the control group ( t = 4.93, P < 0.05). Total response rate was significantly higher in the observation group than in the control group [78.26% (36/46) vs. 58.70% (27/46), χ2 = 4.08, P < 0.05]. The incidence of adverse reactions was significantly lower in the observation group than in the control group [23.91% (11/46) vs. 45.65% (21/46), χ2 = 4.79, P < 0.05]. The 2-year survival rate was significantly higher in the observation group than in the control group [43.48% (20/46) vs. 23.91% (11/46), χ2 = 3.94, P < 0.05]. Conclusion:Nedaplatin combined with docetaxel is highly effective on epithelial ovarian cancer. The combined therapy can greatly reduce serum CA125, CA199, and CEA levels but has no great effects on T lymphocyte subsets. It can increase the survival rate but has no serious adverse reactions.
RESUMO
OBJECTIVE：To o ptimize the t ype of nervous system medicines in National Essential Medicine List of China. METHODS：Various editions of WHO Essential Medicine Model List （WHO EML ）were consulted ，the collection of nervous system medicines was analyzed statistically ，and 2017 edition of WHO EML was compared with 2018 edition of National Essential Medicine List of China （NEML）. RESULTS ：During 1977-2017，the total number of nervous system medicines and disease coverage included in each edition of WHO EML had little change. Compared with 2017 edition of WHO EML ，2018 edition of NEML contained more medicines for nervous system disease （54 medicines vs. 30 medicines），and covered more disease types ， such as dementia （huperzine A ）and neuralgia （pregabalin），etc. However ，for the treatment of multiple sclerosis ，neuralgia， dementia and other diseases ，there were not many medicines to choose ，and some similar medicines （with the same or similar mechanism of action ）were collected repeatedly and some medicines had serious adverse reaction. CONCLUSIONS ：It is suggested that National Essential Medicine List should be continuously optimized and perfected ，the varieties of essential medicines for the treatment of nervous system diseases should be increased appropriately ，for improving the treatment effect of such diseases and reducing the cost burden of patients.
RESUMO
OBJECTIVE:To observe clinical efficacy and safety of recombinant human interleukin-11 (rhIL-11) in the treat-ment of chemotherapy-induced thrombocytopenia. METHODS:86 patients with thrombocytopenia induced by chemotherapy were selected and divided into control group and observation group according to random number table,with 43 cases in each group. Con-trol group was given platelet transfusion 10 IU,once every 2-3 d;observation group was given Recombinant human IL-11 for injec-tion 25-50 μg/kg,qd. Both groups received treatment for 14 d. Clinical efficacies of 2 groups were observed as well as platelet count before and after treatment. The duration of platelet decrease and recovery,the occurrence of ADR were compared between 2 groups. RESULTS:The total effective rate of observation group was 81.40%,which was significantly higher than 62.79% of con-trol group,with statistical significance (P0.05);after treatment,platelet count of 2 groups increased significantly,and the observation group was significant-ly higher than the control group,with statistical significance(P0.05). CON-CLUSIONS:rhIL-11 shows good therapeutic efficacy in the treatment of chemotherapy-induced thrombocytopenia,and can signifi-cantly improve platelet count,shorten the duratione of platelet decrease and recovery with good safety.
RESUMO
Objective:To find the best synthesis method of 6-benzyl-1-[ ( benzyloxy ) methyl ]-3-hydro-xy-5-(hydroxymethyl)pyrimidine-2,4(1H,3H)-dione e for observing the change of its biological activity after N-3 hydroxylation .Methods:After trying some N-hydroxylation methods , the target compound was successfully synthesized via one-pot oxidizing process by sodium hydride ( NaH) and 3-chloroperbenzoic acid( m-CPBA);the anti-HIV reverse transcriptase ( RT) activity and integrase ( IN) activity of the tar-get compound was assayed via enzyme-linked immunesorbent assay ( ELISA) and phosphorylation of DNA package method .Results:The target compound could be obtained through the improved m-CPBA oxida-tive method by only one step , and the yield of the reaction could reach 60%-70%.And the structure of this compound was identified by 1 H NMR, 13 C NMR and MS;The activity result showed it added the an-ti-HIV IN activity after N-3 hydroxylation as well as retained the anti-HIV RT activity.Conclusion:The improved m-CPBA oxidative method is a convenient and efficient way to prepare the compound 6-benzyl-1-[(benzyloxy)methyl]-3-hydroxy-5-(hydroxymethyl)pyrimidine-2,4(1H,3H)-dione e which has both anti-HIV RT and IN activity .
