ABSTRACT
ObjectiveTo compare the recovery rates calculated according to different criteriain patients with urogenital Chlamydia trachomatis (Ct) infection after treatment with azithromycin. Methods Clinical data on outpatients who were diagnosed with urogenital Ct infection and treated with azithromycin in the sexually transmitted disease(STD) outpatient clinic of Tianjin Medical University General Hospital were retrospectively reviewed. Recovery rates were calculated according to the improvement of symptom and (or) reexamination results of Ct at 1,5 and 9 weeks after the end of treatment.ResultsSignificant differences were observed between the recovery rates calculated according to symptom improvement and those according to laboratory reexamination results.No obvious correlation existed between the presence of symptom and positive reexamination results.The recovery rates calculated according to the second reexamination result differed significantly from those according to the first reexamination result,but were similar to those according to the third reexamination result. ConclusionsThe cure of Ct infection should be determined according to laboratory test results,and two times of reexamination at 1 and 5 weeks after the final treatment are recommended.
ABSTRACT
Objective To investigate effects of α-crystallin on proliferation of lipopolysaccharide (LPS)-activated retinal microglia and bioactivity of iNOS.Methods The retinal microglial cells cultured in vitro were analyzed and their purity was identified by cell immunofluorescence and flow cytometry.After microglia cells being intervened using LPS and α-crystallin at various concentrations,influence of α-crystallin on activity of LPS-activated retinal microglia was detected by MTT method and level of NO was measured by RT-PCR to observe changes of iNOS expression in microglia.Results Purity of primary cultured microglial cells was 94.15％ by GSA-IB4 immunohistochemical identification and 93.34％ by CD11b flow cytometry.α-crystallin of 10-4g/L awakened activity of microglia induced by 10-6g/L LPS (P ＜ 0.01).Expressions of iNOS protein and mRNA showed significant decrease in combined treatment group (P ＜ 0.05).Conclusion In clinical condition,α-crystallin decreases the harm of microglial cells on retinal ganglial cells (RGCs) after optical nerve injury by inhibiting the microglia cells to produce NO and iNOS.
ABSTRACT
A method for rapid and accurate distinction of Radix Angelica sinensis and Levisticum officinale Koch was developed after detailed studies of their gross appearnce,specific characteristics of powdered tissue and TLC analysis.
