Objective To evaluate the diagnostic value in pulmonary interstitial fibrosis by transbronchial lung biopsy(TBLB) and immunohistochemistry. Methods The lung tissue samples were obtained from 20 cases of pulmonary fibrosis due to different causes, including 9 cases of idiopathic pulmonary fibrosis(IPF) and 11 cases of pulmonary fibrosis caused by chronic obstructive pulmonary disease (PF COPD), by means of transbronchial lung biopsy. Hematoxylin and eosin staining, Masson trichrome staining and immunostaining with anti type Ⅲ collagen and anti type I collagen multiclonal antibodies were performed. Differences in clinical characteristics, pathological manifestations, levels, types and distribution of proliferation of collagen fibers between IPF and PF COPD were compared. Results The proliferation of collageneous fibers was significantly higher in IPF than in PF COPD( P

By collecting literatures on apoplexy recorded in"Database of Basic TCM disease"from 2001 to 2005,we statistically analyzed changes on volume of documents,major authors,major journals,and contents of study in these literatures.

Co-citation analysis, co-word analysis and strategic coordinates are combined to make known the subject theme evolu-tion. The research history of general surgery is described by eo-citation eluster analysis, citation strategic diagram is pictured by the theory of strategy coordinates to learn more about the novelty and attention of each hot topic. The present research focused on general surgery that would be found by co-words cluster analysis, and stages of development about each topic are discussed by strategic coordinates based of cluster results. It is helpful to provide a decision-making reference for professionals and managers.

Objective: To construct the Behavior Inhibition Scale. Methods: The compilation of items was in accordance with the content validity of seven kinds behavior inhibition. The Self Consistency and Congruence Scale and SCL-90 were also applied as validity index. Results: Factor analysis on 660 subjects rating on original 86 items of Behavior Inhibition Scale yielded seven factors composed of 42 items, measuring the inhibition of help-seeking, self-confidence, independence, negativeness, alienation, dominate, and refuse, respectively. Behavior inhibition correlated significantly with SCL-90 and self congruence, and significant sex and education differences were also detected. Conclusion: The Behavior Inhibition Scale has good reliabilities and well validated.

Objective: To investigate the characteristics of Behavior Styles personality dimension among subjects of dif- ferent age, genders, marriage status, and occupations. Methods: After subjects fulfilled Chinese Personality Scale (QZPS), score differences of Behavior Styles and its sub- factors were compared among age, genders, marriage status, and occupa- tions. Results: Significant differences were detected among different age, genders, and occupations. Males have lower scores than females; the elder the subjects, the higher the scores; executives and technicians have the same scores, and both have higher scores than workers and peasants. Some interactions were also significant. Conclusion: There were sig- nificant differences among subjects of different gender, age, and occupation.

Objective To evaluate the safeness of this treatment by comparing the serum IGF-Ⅰ and IGFBP3 concentration level before and after receiving rhGH treatment in pediatric patients.Methods 30 pediatric patients in our hospital receiving rhGH treatment were subjected to monitor serum IGF-Ⅰ and IGFBP3 level before and after the treatment and calculate the IGF-Ⅰ and IGFBP3 ratio.At the same time the serum T3,T4 and TSH are also assayed.Results The average increase of booly heights was(8.77?3.01)cm /y(t=7.773,P0.05),but the serum IGFBP3(t=3.759,P0.05).However,there was statistical significance of the serum IGFBP3 level between subgroups(f=22.964 P0.05).Conclusion The serum IGF-Ⅰ and IGFBP3 level are able to be used as one of clinical evaluation benchmarks to detect the risks of inducing tumor during the rhGH treatment in the pediatric patients.

The key reason for reparative process interruption of femoral head necrosis is the formation of hardening layer, which make it hard for medicine to act on the necrosis center. The research on formation mechanism of hardening layer is limited and the reason for reparative process interruption is unknown. Based on lots of pathological section and literature data, four hypotheses about the reason for reparative process interruption are proposed, including resource competition, damage of stress, disturbance of nerves and stasis of blood vessel. The internal mechanism of incomplete reparation and chronicity of hardening layer was analyze from different aspects. The four hypotheses provides a new thinking for study the reason for reparative process interruption.

Objective To establish a recombinant retroviral vector containing insulin-like growth factor-1(IGF-1) gene and to provide the basis for the application of IGF-1 in treating nervous system diseases such as stroke.Methods The plasmid pcDNA3.1-IGF-1 was cut by EcoR I/Xho I,and subcloned to retroviral vector pLXSN,resulting in the recombinant plasmid(pLXSN-IGF-1.)The recombinant IGF-1 expression vector was evaluated by using enzyme cutting and sequencing.By the Lipofectamine 2000,pLXSN-IGF-1 was transferred to packaging cell line-pA317.Culture supernatant of these cells was detected for titration of the recombinant virus.Results The two fragments from recombined IGF-1 eukaryotic expression vector by EcoR I and Xho I represented 400?bp and 6.0?kb by agarose electrophoresis,and PCR showed positive fragment which was about 400?bp long,and sequence analysis showed the same sequence as expected.The cell line pA317-IGF-1 was established,and average virus titer of the recombinant virus in the culture supernatant was about 6.5?10~5 CFU/ml.Conclusion A recombinant retroviral containing IGF-1 gene was successfully constructed.

Objective To assess the effectiveness of Chinese medicine treatment in endometriosis(EMT) by evidence-based medicine methods.Methods Retrieve articles mainly from Wanfang data,VIP information,CNKI and China TCM Database.Bring the articles report into research on the basis of strict quality evaluation.Consolidate cure rate and effective rate for meta-analysis.Results Based on 8 articles report,cure rate of Chinese medicine treatment is superior to western medicine treatment,and effective rate is equivalent to western medicine treatment.There is no side effect and other harmful consequence in evidence.Conclusions Chinese medicine treatment is superior to western medicine treatment in treating EMT.However,existence of some data methodological problems maybe directly affect the authenticity of the findings.So,more rigorous,randomized controlled trials should be designed in order to draw more reliable conclusions.

OBJECTIVE: To study extraction method of anthraquinones components of Radix et Rhizoma Rhei and optimize extraction technology.METHODS: Ultrasonic extraction,heating reflux extraction and soxhlet extraction were adopted to extract Radix et Rhizoma Rhei respectively.3 kinds of extraction technology were compared with the content of total anthraquinone,aloe-emodin,rhein,emodin,chrysophanol,physcione as index.The extraction technologies of UV and 5 kinds of anthraquinone compounds were optimized by uniform design method on the basis of previous study.RESULTS: Heating reflux extraction which was optimal extraction technology was as follows: extracting time of 90 min,extracting for 1 time,methanol concentrations of 95%,medicinal mesh of 2.000 7.Comprehensive score of anthraquinones could reach 6.556.CONCLUSION: The extraction technology is reasonable,available in quality control.
