Chinese Journal of Medical Education Research 2003;0(02):-
The study on medical education directly affects the quality of education and cultivation of medical professionals as well as the level of running school.It is very important for the medical colleges to take some measures to solve these problems existing in medical teaching reform and research,such as renewing teachers' ideas,enhancing the standardization of management,increasing the enthusiasm of the teachers etc.

Objectives To review the publications of general practice research in China mainland from 1993 to 2012.Methods The literatures on general practice research published in China mainland from 1993 to 2012 were retrieved from the China Journal Full Text Databases , Wanfang Databases and PubMed . The publications were analyzed using the literature management software NoteExpress 2, Excelland SPSS 19.0.Results A total of 16 349 Chinese publications and 266 English publications of general practice research were collected .The amount of publications was gradually increasing during 1993 and 2012 and there was a sharp increase in the Chinese publications from 2008 to 2012 comparing with the previous years.The Chinese publications in China′s core journals accounted for 32.39%(5 295/16 349) of total of publications;and the English publications in SCI journals accounted for 96.62% ( 257/266 ) of total publications.The authors from community health service facilities accounted for 76.01%(12 427/16 349) of Chinese publications; while authors from research institutes and universities accounted for 61.65%(164/266) of the English publications .Results showed that 37.59% ( 6 145/16 349 ) and 37.12%( 6 069/16 349 ) of the Chinese publications were commentaries and descriptive studies , only 9.57%(1 565/16 349) were randomized controlled trials;52.63% (140/266) of the English publications were descriptive studies and 9.02% ( 24/266 ) were randomized controlled trials .60.75% ( 9 932/16 349 ) of the Chinese publications and 75.94% ( 202/266 ) of the English publications were focused on clinical topics.Conclusion Although the number of general practice publications has been increasing during 1993-2012, the quality of publications is still less satisfactory and need to be further improved .

Objective Developing an index system to evaluate the community teaching bases of general practice, for the purpose of identifying and completing at least one demonstration teaching base for general practice in each city in 2010. Methods Initial building of the index system by means of Delphi method and experts interview, followed by selection of experts for consultation, statistical analysis on the results of letter inquiries, and rounded up by the establishment of the index system for evaluation in the end. Results The recovery rates of a two-round Delphi questionnaire response are 94.12% and 100.00%respectively. Expert's authority degrees of five indexes are all over 0.8, which suggests high expert's authority. The average coordination coefficient of two-round Delphi experts consultation is 0.262and 0.534 respectively, showing good experts coordination. In the end, the study established four first-class indexes, ten second-class indexes, 41 third-class indexes and five additional indexes. Conclusions The index system is established in view of the current development of community teaching bases. It focuses on evaluating teachers, the teaching process and base's function. The evaluation system provides reference for selecting demonstration community teaching bases of general practice.

Objective To study the validity of RAND-UCLA (Rand Corporation and University of California at Los Angeles) consensus panel method in developing guidelines of referral indications for low back pain (LBP).Methods Evidence-based clinical guidelines for LBP management at community level and its referral guidelines published since 2001 and other tools were retrieved with varied tools.All clinical guidelines met inclusion criteria were evaluated with clinical studies and evaluation tools (AGREE).An pool of indication items was established based on evidence for developing referral indications for LBP, which were added by RAND-UCLA consensus panel method, and alternative referral indications were selected and clinical guidelines for LBP referral were established.Results A total of 15 copies of clinical guidelines from nine countries or regions were included in it after critical appraisal.Four copies of referral guidelines from two countries were included.Referral indications for LBP were derived directly from the RAND-UCLA consensus panel process, consisting of 44 referral indications for three groups (immediate, urgent and routine referral).Conclusions The RAND-UCLA consensus panel method is a more useful and practical tool in developing clinical guidelines, referral guidelines, which is worthwhile being recommended and spread.

Objective To explore the predictive value of CT radiomics and morphological features for the prognosis and survival in non-small cell lung cancer(NSCLC)patients.Methods The clinic data of 300 NSCLC patients(300 lesions)were downloaded from the Cancer Imaging Archive,with 210 randomly selected as the training set and 90 as the test set.According to the prognosis and survival,the patients were divided into two groups with survival period≤3 and>3 years.3D Slicer software was used to delineate the regions of interest layer by layer in CT images,and the radiomics features were extracted from each region of interest.Both t-test and least absolute shrinkage and selection operator were utilized for radiomics feature screening.Three types of prediction models,namely radiomics model,morphological model and combined model,were constructed with Logistic regression,whose performances were evaluated using the receiver operating characteristic(ROC)curve.Results The differences in radiomics labels and mediastinal lymph node metastasis between the training set and the test set were statistically significant.For radiomics model,morphological model and combined model,the area under the ROC curve was 0.784(95%CI:0.722-0.847),0.734(95%CI:0.664-0.804)and 0.748(95%CI:0.680-0.815)in the training set,and 0.737(95%CI:0.630-0.844),0.665(95%CI:0.554-0.777)and 0.687(95%CI:0.578-0.797)in the test set,which demonstrated that radiomics model had the best diagnostic performance.Conclusion The CT radiomics model can effectively predict the prognosis and survival in NSCLC patients.

Via an insufficient coat protein complex I (COPI) retrieval signal, the majority of SARS-CoV-2 spike (S) is resident in host early secretory organelles and a tiny amount is leaked out in cell surface. Only surface-exposed S can be recognized by B cell receptor (BCR) or anti-S therapeutic monoclonal antibodies (mAbs) that is the trigger step for B cell activation after S mRNA vaccination or infected cell clearance by S mAbs. Now, a drug strategy to promote S host surface exposure is absent. Here, we first combined structural and biochemical analysis to characterize S COPI sorting signals. A potent S COPI sorting inhibitor was then invented, evidently capable of promoting S surface exposure and facilitating infected cell clearance by S antibody-dependent cellular cytotoxicity (ADCC). Importantly, with the inhibitor as a probe, we revealed Omicron BA.1 S is less cell surface exposed than prototypes because of a constellation of S folding mutations, possibly corresponding to its ER chaperone association. Our findings not only suggest COPI is a druggable target against COVID-19, but also highlight SARS-CoV-2 evolution mechanism driven by S folding and trafficking mutations.
