Objective To investigate the efficacy of widely used antibiotics for urogenital Chlamydia trachomatis infection in recent 5 years.Methods A total of 2 809 cases of Chlamydia trachomatis urogenital infected patients who visited STD clinics of Tianjin Medical University General Hospital from 2006 to 2010 were collected.All the patients had accomplished a course of treatment of azithromycin, minocycline, moxifloxacin or clarithromycin and followed up for 3 months (once every month).Cochran-Armitage trend test was used to analyzed the antibiotics effect changing trends overtime.Results From 2006 to 2010, the etiology clearance rates of azithromycin were 76.70% (79/103), 74.19% (92/124), 74.13% (106/143), 71.43% (100/140) and 70.77% (92/130), respectively;those of minocycline were 75.31% (61/81), 64.67% (97/150), 66.53% (159/239), 65.05% (188/289) and 63.03% (104/165), respectively;those of moxifloxacin were 88.82% (167/188), 86.23% (119/138), 82.96% (185/223), 81.19% (233/287) and 81.03% (158/37), respectively;those of clarithromycin were 82.93% (34/41), 80.49% (33/41), 79.25% (42/53), 78.18% (43/55) and 75.00% (18/24), respectively.Ochran-Armitage trend test showed that antimicrobial efficacy of moxifloxacin for urogenital Chlamydia trachomatis infection rates declined year by year (P<0.05), while those of azithromycin, clarithromycin and minocycline did not decline significantly (all P>0.05).Conclusions The etiology clearance rate of moxifloxacin is the highest but gradually declines by years, and that of azithromycin takes the second place, while the treatment efficacy of minocycline is lower but quite stable.The number of cases treated with clarithromycin is too small to draw a conclusion.

Persistent Chlamydia trachomatis urogenital tract infection may lead to pelvic inflammatory disease, ectopic pregnancy and tubal infertility in women, and urethritis, epididymitis and other complications in men, which is a hotspot and chanllenge in disease control at home and abroad. In recent years, many researches have shown that Chlamydia trachomatis aberrant reticulate body may be one of the major causes of persistent infection. This review summarized the genomic and proteomic characteristics of Chlamydia trachomatis aberrant reticulate body induced under various conditions in vitro, aiming to elucidating its role in antimicrobial resistance. The identification of persistent infection-related factors, providing new diagnostic targets for the detection of subclinically refractory long-term infections, is a prerequisite for finding appropriate methods to diagnose and treat the complications of Chlamydia trachomatis infection and is crucial for identifying new targets in the post-genomic era.

Objective To provide reference for the optimization and improvement of interoperability between the standard system of the Chinese Pharmacopoeia and other standards.Methods The interoperability of various pharmacopoeia standard systems was compared by searching for citations from the Chinese Pharmacopoeia,the United States Pharmacopoeia-National Formulary,the European Pharmacopoeia,the Japanese Pharmacopoeia,and other standards,including references to domestic regulations and guidelines,standards of the International Organization for Standardization,guidelines from the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use,documents of the World Health Organization,and standards from other countries and international organizations.Results In recent years,pharmacopoeias in the world had continuously increased the citation of non pharmacopoeial standards.The types,quantities,and fields of the United States Pharmacopoeia-National Formulary referencing other standards far exceed those of other pharmacopoeias.The Chinese Pharmacopoeia cites the least number of other standards.Conclusion It is suggested that the Chinese Pharmacopoeia should enhance the interoperability with other standard systems in the standards of various professional fields,enhance the openness,harmonization and advantages,and form a more complete standard system.

The purpose of this paper is to review the research on the influence and mechanism of intolerance of uncertainty （IU） on anxiety both at home and abroad in recent years. IU refers to the individual's disgust response due to the intolerance of perceived lack of prominent， critical or sufficient information， and it has individual tendency. IU plays an important role in the occurrence and development of anxiety， but the specific process and mechanism remain unclear. This paper reviews the influence of IU on anxiety， and clarifies its mechanism of action on the generation and development of anxiety from the perspectives of cognition， emotion and behavior， so as to provide references for preventing the development of general anxiety into anxiety disorders and developing new psychological intervention and treatment strategies.
