The original articles cited by other researchers were 7.86, 6.54, 5.48, 2.98 and 1.78, with an average of 5.62. The highest one was citated by 68 times. The most frequently cited authors were from 30 provinces of China and the city Beijing, Shanghai and Tianjin were the three topest cities among other cities in the naion. There were 461 citing journals, and there was 191 items self citsted, self-citing rate is 0.045. Conclusion Chinese Journal of Orthopaedics has published high quality articles.

15 0 mU/L treatment with 20 mg levothyroxine a day was needed. Conclusions The thyroid function of elderly patients, taking low oral dose of aminodarone for cardiac arrhythmias, especially those with cardiac pacemaker was affected early (on the 6th day) and significantly. However, it recovered spontaneously but gradually in most of the cases even with abnormal thyroid hormone levels throughout the study. Therefore, oral low dose amiodarone (in one year) is safe for the elderly patients, but they must be monitored closely in the first 6 months.

The time that industrial microbiology alone took the course is short,so it requires a discussion about reform on teaching content and method.The thesis first discusses the reforms on teaching content from basic theory knowledge combining to scientific research,experiment and producing practice.Then reforms the teaching method,such as adopting the computer-assisted instruction(CAI) pattern,combining the problem-based learning(PBL) and case-based studying(CBS) each other,and leading into partly bilingual education method.By all above investigation and discussion practice in two aspects,the students produces deep interest to industrial microbiology,and reached the purpose of teaching reform.

Objective To analyze the core authors, and their organizations, geographical regional distribution of Chinese Journal of Orthopaedics. Methods The core authors, coauthors and their organizations whose articles were published in Chinese Journal of Orthopaedics between 1995 and 2004 were quantitatively analyzed using literature search through CMCI, which programmed by the People's Liberation Army Medical Library and their geographical regions distribution, the organizations of whom had high quantitative publication were determined using literature metrology methods. Results There were 2660 articles published in Chinese Journal of Orthopaedics between 1995 and 2004. All of 1123 authors of 2660 articles had only one article published which accounted for 69.67% of total first authors on the Chinese Journal of Orthopaedics in ten years. There were 2385 articles with one or more coauthors and the cooperative rate was 89.66%, and cooperative degree was 4.11 in the period of time. There were 275 articles with single author, which accounted for 10.34% of total articles. The articles written by the authors from military hospitals, university affiliated hospitals and provinces-level hospitals were 646(24.28%), 1091(41.01%) and 706(26.54%), respectively during the period. There were 218 core authors with 959(36.05%) articles published and there were 20 high-quantities organizations with 1007(37.86%) articles published in this study. The number one region of published articles was Beijing with 667(25.08%) articles. There were 2443 (91.84%) articles pressed from the organizations of affiliated hospitals of universities, provinces-level hospitals and army hospitals. Among them, Tianjin hospital (101 articles), Beijing Jishuitan hospital (100 articles) and affiliated Xijing hospital of the 4th military medical mniversity (79 articles) occupied 10.53% of the pressed papers and they were in the first three positions. Conclusion Authors of Chinese Journal of Orthopaedics have a wide distribution and highly cooperative rate. There were a group of active and talented core authors who has a great influence on the journal.

Objective: To study the DNA ploidy and DNA index (DI) in human benign and malignant bronchopulmonary change, and evaluate their value in diagnosis of benign and malignant bronchopulmonary diseases.Methods: The DNA ploidy and DI were analysed by image cytometry analysis (ICM) in 39 cases of bronchitis, 45 cases of squamous metaplasia, 45 cases of dysplasia,and 63 cases of carcinoma.Results: The mean DI for bronchitis and squamous metaplasia were 0.92 and 1.03 respectively, and dysplasia was 1.34,while the mean value for carcinoma was 1.72.Among the four groups,the difference was of evident statistical significance.Conclusion: The DNA content and DNA aneuploidy are with different percentage in benign and malignant bronchopulmonary pathological change.Quantitative analysis of the DNA ploidy and DI may be beneficial in diagnosis and differencial diagnosis of benign and malignant changes,which can provide objective data for clinical treatment and prognosis.

Objective To analyze the therapy and prognosis of palindromic ovarian carcinoma. Methods The clinical data of 40 cases of palindromic ovarian carcinoma were reviewed retrospectively. Results After the first surgery, the mean recurrent time of the patients with remained tumors smaller than 2 0 cm was (37 26?11 79) months, and that of the patients with remained tumors larger than 2 0 cm was (7 88?1 49) months. There was a significnat difference in the mean recurrent time between the two groups of the patients with different size of remained tumors(P0 05). Conclusion The recurrence of ovarian cancer was related to the size of remained tumor. Secondary operation plus chemotherapy could improve the short-term survival rate of the patients with palindromic ovarian carcinoma.
