OBJECTIVE:To observe the effects of thalidomide in the growth of the human ovarian cancer cells (OVCAR-3) and HCT-8 as well as the angiogenesis in tumor tissue through building a model of heterograft of nude mice with human tumors. METHODS: After implanting human tumors in nude mice for modeling, the inoculated nude mice were intragastrically administered different dose of thalidomide, with tumor growth condition observed and compared with control group. The diversity of microvessel density(MVD) in tumor tissue was detected by immunohistochemistry. RESULTS: Middle and high dose thalidomide could significantly inhibit the growth of OVCAR-3 human tumor in nude mice(P

Objectives To provide outline for the Research & Development department of hospitals making research strategy by analyzing the quantity of publications and their cited status for the top 20 hospitals in SCI and MEDLINE, and the top 100 hospitals in domestic publications in 2008. Methods The number of publications and their cited times for the first 20 hospitals in SCI and MEDLINE, and the top 100hospitals in domestic publications in 2008 were analyzed with bibliometric analysis. Results Compared with 2007, the increased number and ratio of publications in SCI and MEDLINE for the top 20 hospitals were 1050, 51.19% and 658, 15.04%, respectively; for top 100 hospitals, the average decreased number of domestic publications was 2.08, and the number of cited publications was increased 202.52 and the increased ratio was 13.51%. Conclusions The SCI publications from top 20 hospitals increase sharply, the increase of the MEDLINE articles from the top 20 hospitals is slowly. The negative growth is showed in the number of domestic articles for the top 100 hospitals. In addition, the increase of cited articles is slowly and disproportion.

Objective To investigate the authors, the institution and endemic distribution of these authors of Chinese Journal of Orthopaedics, and understand the current situation and problems in the field of Orthopaedics. Methods The authors, the co-authors and the core authors of papers published in Chinese Journal of Orthopedics from 2005 to 2009 were quantitatively analyzed using literature search through CMCI.The distribution of institution, region and highly quantitative organization were also analyzed. Results The 1182 papers were published by the Journal within 5 years. There were 1108 papers with one or more co-authors; the cooperative rate and degree were 93.74% and 5.02, respectively. 74 papers were written by single author, which accounted for 6.26% of all papers. 615 authors (75.18% of all first authors) published only one paper. There were 295 (24.96%) papers from 67 (8.19%) core authors. 601 (50.85%) papers were from 20 high-productivity institutes. The top three high-productivity institutes were Tianjin hospital, Beijing Jishuitan hospital and Nanjing Drum Tower hospital of Nanjing University Medical School. The number of papers were 89 (7.53%), 75 (6.35%) and 43 (3.64%), respectively. The number of papers from the teaching hospital,provincial or municipal hospitals, military hospitals were 722 (61.08%), 226 (19.12%) and 157 (13.28%),respectively. According to the distribution of Province, Beijing was the first of place with 264 (22.34%) papers, followed by Shanghai by 160 (13.54%) papers and Tianjin by 136 (11.51%) papers. The distribution range of the authors has been expanded to five countries. Conclusion The influence of the Chinese Journal of Orthopaedics has greatly increased. Authors of the Chinese Journal of Orthopaedics have a highly cooperative rate. There is a group of active and talented core authors who has a great influence on the journal. But the number of core authors and the papers published by core authors need to be expanded.

OBJECTIVE: To evaluate the status quo and trend of the application of narcotic drugs and psychotropic substances Ⅰ in Yangzhou area.METHODS: The narcotic drugs and psychotropic substances Ⅰ used in 124 hospitals of Yangzhou from 2005 to 2007 were analyzed in respect of consumption sum,DDDs and DDC etc. RESULTS: A total of 13 kinds of narcotic drugs and 4 psychotropic substances Ⅰ were used in the 124 hospitals,and the consumption sum of these drugs increased year on year.Fentanyl remained at the first place in terms of DDDs in each year,Remifentanil Hydrochloride for Injection and Sufentanil Citrate showed an obvious increasing trend in consumption,but the consumption of Bucinnazine Hydrochloride Injection(Tablet),Triazolam and Buprenorphine Hydrochloride Injection decreased to a large extent.CONCLUSION: The use of narcotic drugs and psychotropic substances Ⅰ in the 124 hospitals in Yangzhou area was basically in line with the standard.However,the DDDs of Pethidine Hydrochloride Injection had all along dominated the front place suggesting that clinicians should attach great importance to the standard treatment of cancer pain.

Recurrence and metastasis are main causes ofsurgical treatment failure of non-small cell lung cancer.In prevention of non-small cell lung cancer recurrence and metastasis,Chinese medicine has achieved a certain effect. It has been proved by clinical use of Chinese patent drugs, compound modification based on syndrome differentiation, integrated traditional Chinese and western medicine treatment, and molecular mechanism of anti-recurrence and metastasis, though there are still some problems. This article reviews the recent clinical and experimental research status.

Objective To conclude nursing experience of second anastomotic leakage after radical gastric cancer surgery. Methods The present study compared the differences of clinical symptoms between these two anastomotic leakages, and found a way to detect latent anastomotic leakage with an unobvious abdominal sign accurately and opportunely. The study also intervened in the patient′s observation, psychological condition, peritoneal irrigation and nutritional support after surgery. Results The patients were discharged from the hospital after cured with well controlled condition. Conclusions In order to make an early detection and treatment of the second anastomotic leakage, nurses should not only observe the abdominal sign, but also observe the systematic poisoning and concomitant symptoms.

Liver cirrhosis is the advanced stage of various chronic liver diseases,and its complications include portal hypertension,esophageal and gastric varices,hepatocellular carcinoma,etc. Transient elastography( TE),a noninvasive method for liver stiffness measurement( LSM),has been used widely to detect liver fibrosis qualitatively and quantitatively. Recently,correlations were observed for LSM with liver cirrhosis and its complications. This article reviewed the studies focused on these correlations,as well as the clinical application of TE.
