BACKGROUND: To review progressions in the pharmacological study of natural plant Ficus carica L. (fig), summarize its main pharmacological effects so as to manifest values in clinical practice.DATA SOURCES: .By computer retrieval system, the relevant papers on the researches on Ficus carica were retrieved on Medline from January 1950 to September 2004 and limited at the referred word "Ficus carica" in English. Simultaneously, the relevant papers were searched by the computer on China National Knowledge Infrastructure (CNKI) database from January 1999 to September 2004, focusing on the referred word "Fieus carica" in Chinese.STUDY SELECTION: Of all the relevant papers, ones focusing on the pharmacological study of Ficus carica were selected and the whole text were checked, meanwhile those had no relation with the pharmacological latex as well as various constituents and preparations. Exclusion criterion:repeated studies.DATA EXTRACTION: A total of 226 papers were checked on the study of Ficus carica, 30 papers were consistent with the standards. Among the 196 excluded papers, 189 were excluded because they were clinical experience report or repeated studies, 7 were reviews.DATA SYNTHESIS: Investigations of the fig, its leaves and latex as well as various constituents and preparations, have revealed many pharmacological effects such as: anti-tumor effects, the ability to mediate body metabolism, mediating hyperglycemia, hyperlipidemia and cholesterol levels, enhancing oxidation resistance, antibiotic effects, antivirus effects, the ability to mediate immunity, activating blood coagulation etc. It also may play an important role in supportive therapy in tumor treatment by reducing toxicity and side effects in actinotheraphy and chemotherapy. Several reports of anaphylaxis after fig intake have reported both in China and abroad.CONCLUSION: As an herb, fig has wide pharmacological effects and clinical practise values. The main pharmacological studies of it were focused on its anti-tumor effects and the ability to mediate body metabolism.Separation and purification of its active components and determining the interactions between them as well as the pharmacological and toxicological effects need further study. New pharmacological effect s will be found by studying various fig extracts.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2010;(1):21-24
Objective:To observe the anatomic characteristics of supratubal recess and the morphological change of it in the sick ear. To investigate the relation between the morphological changes of supratubal recess and otitis media.Method:Using high resolution CT to observe and measure the supratubal recess of the normal ears and the ailing ones.Result:For the normal adults, the anteroposterior diameter of the supratubal recess is(3.83±1.28)mm,the vertical diameter(3.67±1.14)mm,the height(3.76±0.36)mm;and the length of the cog is(2.84±0.38)mm.The size of the supratubal recess showed no significant difference between left and right(P>0.05).There was no relationship between the size of the supratubal recess and pneumatization of mastoid cells (P>0.05).There was significant differences in size of the supratubal recess between normal ears and the ears with cholesteatoma(P<0.05),but there was no relationship between the size of the supratubal recess and pneumatization of mastoid cells(P>0.05)in the ears with cholesteatoma.There was no significant differences in size of the supratubal recess between normal ears and the ears with chronic otitis media(P>0.05).In the ears with cholesteatoma,40% had osseous destruction in supratubal recess.Conclusion:For the normal adults, the size of the supratubal recess showed no significant difference between left and right, and there was no relationship between the size of the supratubal recess and pneumatization of mastoid cells. Anterior tympanic isthmus , posterior tympanic isthmus and supratubal recess which is the supplement of the formers constitute the air way between attic and mesotympanum. The supratubal recess of the cholesteatoma is smaller than the normal, when the eustachian tube dysfunction occurs, the air way in the middle ear would herein be affected, and cholesteatoma forms eventually. There was no significant differences in size of the supratubal recess between normal ears and ears with chronic oti-tis media, as in the clinic.The effect of the supratubal recess should be taken into account when we consider the pathogeny and treatment of the middle ear cholesteatoma.

Chinese Journal of Orthopaedic Trauma 2012;14(7):566-570
Objective To assess the interobserver reliability and intraobserver reproducibility of Neer classification system and its influencing factors.Methods The present study reviewed the series preoperative radiographs (including those of scapular anteroposterior view,scapular lateral view and modified Velpeau axillary view and an axial CT scan) of 40 patients who had been treated in our department from January 2010 to December 2010 for proximal humeral fractures.The radiographs were assessed by 12 individual observers on 2 separate occasions with an interval of 3 months at least Half of the observers (the professional group; n =6) had received a shoulder fellowship training and the other half (the control group; n =6) had not All the observers were asked to categorize the radiographs according to the Neer classification system of 16 types of fractures in a same process.The reliability and reproducibility of the system were assessed with the Kappa statistics.Comparisons of classification agreement were made between the professional group and the control group.We also evaluated the simplified Neer system of only 6 types of fractures with recombinant data.Results The interobserver reliability coefficients were 0.534 and 0.473 for the first and second assessments,with an intraobserver reproducibility coefficient of 0.669.The agreement level in the professional group was significantly higher than in the control group ( P < 0.05).The interobserver reliability coefficients of the simplified Neer system were 0.581 and 0.502,with an intraobserver reproducibility coefficient of 0.680.Use of the modified Neer system did not elevate the agreement level beyond the moderate range.The classification was agreed on by all the observers in 17.5% of the fractures during the first assessment and in 15.0% during the second assessment.Conclusions Neer classification may have fair interobserver reliability and moderate intraobserver reproducibility.Experience of shoulder fellowship training is an important factor influencing the reliability of the Neer system.Simplification of the system may not help increase its reliability.
9.Meta-Analysis on Clinical Efficacy of Integrated Treatment of Traditional Chinese and Western Medicine on Immune Thrombocytopenia
Chinese Journal of Information on Traditional Chinese Medicine 2014;(3):5-9
Objective To evaluate the clinical efficacy of integration of traditional Chinese and western medicine (ITWM) or pure western medicine on the patients with immune thrombocytopenia (ITP). Methods Randomized controlled trials (RCTs) on ITWM treatment of ITP were searched in PubMed, EMBASE, Wanfang database, CBMDisc, CNKI and VIP. Quality of the RCTs was evaluated strictly, and statistical analysis was performed with Cochrane Collaboration’s RevMan5.1.7 software. Results Twenty-two trials involving 1527 patients were included. The results of Meta-analysis showed that the ITWM treatment of ITP significantly improved the total effective rate [RR=1.23, 95%CI (1.17, 1.29), P<0.000 01] compared with that of pure western medicine treatment. Funnel plot showed that publication bias was small. Meanwhile, peripheral platelet count and the number of megakaryocyte which can generate platelet in bone marrow increased, obvious advantage was showed in long-term effect, and adverse reactions were reduced with ITWM treatment in ITP patients. Conclusion The existed limited evidences suggest that ITWM treatment of ITP can significantly improve clinical efficacy. The quantity and quality of research literature were limited, and well-designed randomized double-blind controlled trials with large sample and multi-centers are required for a more reliable conclusion.
