Through the map analysis of various metabolites in rat's urine, the biomarkers in syndrome suitable for Small Qing-Long Decoction (SQLD) were found out, which provided objective basis for the clinical diagnosis and treatment. Based on the rat's urine nuclear magnetic resonance (NMR) spectrum detection of the blank control group, the model group and the SQLD group, the data come from the map by MestRenova pretreatment and integration were analyzed using SIMCA-P+ by (PLS-DA). Then, the corresponding scatter diagram and diagram of loading were re-ceived and the differences of metabolites were found out by the comparison . The results showed that compared with the blank control group, contents of creatinine, guanidinoacetic acid, trimethylamine, taurine, allantoin metabolites in the model group had elevated. And the contents of succinic acid, 2-OG, lactic acid, glycine, methyl nicotine metabolite had decreased. After medication, contents of creatinine, trimethylamine, allantoin, taurine of SQLD group were still higher than the blank control group. However, the contents were reduced compared with the model group. The content of lactic acid was lower than the blank control group, but higher than the model group. There was no statistical significance on changes of guanidinoacetic acid, 2-OG, N-nornicotine. It was concluded that substances found were mainly related to energy metabolism, inflammation and immune resistance, which was especially related to energy metabolism change obviously.

Objective To determine the pharmacokinetic interaction between cefalor and bromhexine in healthy Chinese volunteers. Methods Twelve subjects received a cefaclor (CEF) treatment, a bromhexine (BHX) treatment, and a co-treatment of CEF and BHX with a 3 × 3 Latin square design. The wash-out time between periods was 14 days. The plasma and urine drug concentrations of CEF and BHX were detected by HPLC-UV and LC/MS, respectively. Results All the 12 volunteers completed the study. There were no significant differences in AUC0-t and Cmax of CEF in logarithm between the single administration group of CEF and the co-administration group of CEF with BHX. Two one sided t-test showed that CEF was bioequivalent in the 2 groups. There were no significant differences in tmax, MRT, t1/2, and Clr between the 2 groups. Vd/F was significantly lower in the single CEF group than in the co-administration group of CEF and BHX. There were no significant differences of AUC0-t and Cmax of BHX in logarithm between the single administration group of BHX and the co-administration group of BHX with CEF. Two one sided t-test showed that BHX was bioequivalent in the 2 groups. There were no significant differences in tmax, MRT, t1/2, Vd/F, and Clr between the 2 groups. Conclusion There is no significant pharmacokinetic parameter change in the drug absorption, metabolism, and excretion, but Va/F of CEF significant increases in the co-administration of CEF with BHX. The co-administration of CEF and BHX has no adverse drug interaction. The increase of Vd/F may be a favorable drug interaction, which may be the mechanism of the synergistic effect of the 2 drugs.

OBJECTIVE:To study the pharmacokinetics of prulifloxacin capsules in Chinese healthy volunteers after single and multiple oral administration of prulifloxacin capsules.METHODS:A total of 12 healthy adult subjects were randomly grouped by 3? 3 Latin square,who were assigned to receive oral single dose of 132,264 and 528mg prulifloxacin capsules and multiple doses of 264mg prulifloxacin capsule for 6 days in succession.The blood concentration of NM394-the metabolite of Prulifloxacin was determined by HPLC at different time after oral administration of Prulifloxacin.The simulation and fitting,and computation of parameters were performed using DAS ver1.0 software.RESULTS:All 12 subjects had completed single oral administration test,with no adverse drug reactions appeared during the test.No prulifloxacin but its metabolite-NM394 was identified in the blood sample of subjects.The high,medium and low dosage groups were all fitted two-compartment model.The pharmacokinetics fitted first order kinetics process without gender difference.There was no accumulation and pharmacokinetic parameters change after multiple oral administration of prulifloxacin,suggesting prulifloxacin had no self-enzyme inhibition or induction.CONCLUSION:The established method is sensitive,accurate,reliable and specific,and it can meet the requirement of clinical pharmacokinetic trial.Its parameters are in line with literature reported abroad,with no gender difference among Chinese adults.

The effectiveness of rhIL-11 on thrombocytopenia induced by carboplatin in rhesus monkeys was investigated. Thrombocytopenia was induced in monkeys by i.v. administration of carboplatin at a dose of 15 mg/kg(-1)/d(-1) for three consecutive days. rhIL-11 (50 or 100 micro g/kg(-1)/d(-1)) or Neumega (100 micro g/kg(-1)/d(-1)) were administered s.c. for 14 days beginning one day following the final dose of carboplatin. The results showed that rhIL-11 significantly improved mean platelet nadirs and shortened the mean duration of platelet counts less than 50% of pre-treatment values. Administration of rhIL-11 also resulted in moderate increase of the reticulated platelet, leukocyte and reticulocyte counts in peripheral blood and megakaryocytic and erythroid progenitors in bone marrow. rhIL-11 did not enhance ADP-induced platelet aggregation. These results indicate that rhIL-11 has a potent thrombopoietic effect in vivo and could be an important agent to reduce the severity and duration of thrombocytopenia following chemotherapy.

Objective:To analyze the epidemiological characteristics and track probable imported sources of the local dengue outbreak in Zhangzhou city, Fujian province, 2019.Methods:Serum samples of patients with suspected dengue fever at acute phases were collected for virus detecting and serotyping by real-time fluorescence quantitative RT-PCR. For the positive specimens of local cases, full-length fragments of E gene were amplified by RT-PCR, and were sequenced and analyzed.Result:In 2019, there were 98 local cases of dengue fever in Zhangzhou city, which were concentrated in Zhao’an county, Longhai district and Yunxiao county. In this study, fourteen dengue virus E gene sequences representing different sources in different districts and counties were selected. The amino acid sequence virulence site analysis showed that the local epidemic strains were relatively virulent strains. The gene sequence alignment and phylogenetic analysis showed that all the local strains were classified as DENV-I subgenotype genotype I, divided into a, b and c three different branches. The evolutionary branch a contained all Zhao’an and Longhai sequences and was divided into three sub-branches, the b and c evolutionary branches were both the sequences of Yunxiao. There was a high correlation between the Shenqiao Town in Zhao’an and the Haicheng Town in Longhai. The other areas of the strains were limited to the towns, and the evolutionary branches were close to the other areas in China and countries in Southeast Asia.Conclusions:The indigenous dengue outbreaks in Zhangzhou, 2019 were caused by multiple sources of introduction and originated from other areas in China or from Southeast Asian countries and there was also the possibility of local cross-county transmission.
