In view of the deficiency of class hour and the limitations of classroom teaching in the course of ocular fundus disease, a network teaching platform, based on Browser/Server structure, was explored and constructed to assist classroom teaching. The network platform was constituted with teaching demonstration system, communication-test system, search system, and help system, mainly including 18 functional modules of learning-world et al. The students can be guided with the modules such as navigation, acting as a self-regulated learner through the modules such as learning-world, searching and downloading the related learning materials through the modules such as searching and discussing different learning topics with other students and their teachers through the modules such as forum. The network platform was used for classroom teaching of ocular fundus disease in auxiliary , and the result showed it was helpful to breaking the time and space constraints in conventional teach-ing, expanding the teaching content, solving the difficulties in teaching, improving the students' learning initiative, and realizing the interactive teaching.

In order to prepare monoclonal antibody to σ A protein of avian reovirus(ARV)and es-tablish a sandwich ELISA method for the detection of ARV pathogens.In this study,the σ A pro-tein of ARV was expressed as antigen by prokaryotic expression and used to immunize BALB/c mice.Then,stable hybridoma cell lines were screened,and monoclonal antibodies were prepared.A sandwich ELISA detection method based on monoclonal antibody of σA protein was established,and the sensitivity,specificity,repeatability,and accuracy were tested.The results showed that the recombinant plasmid pET-32a-σA was successfully constructed and well expressed in Escherichia coli.After immunizing mice,two hybridoma cell lines 6B3 and 8E11,which could secrete mono-clonal antibodies stably,were successfully prepared.Both monoclonal antibodies could react with natural ARV.One of the monoclonal antibodies secreted by 6B3 was selected as the capture anti-body and the ARV-positive chicken polyclonal antibody was used as the detection antibody.A sand-wich ELISA method was established to detect ARV by optimizing the reaction conditions.The specific test showed that the method only detected ARV pathogens and no other common chicken viral pathogens were detected.The detection limit was 7.72 X 102 EID50/mL of ARV antigen.The coefficient of variation of the intra-and inter-assay tests were less than 5.0％and the reproducibili-ty was good.Thirty samples were tested simultaneously by σA-sandwich ELISA and PCR,and the results were consistent with each other.In conclusion,a sandwich ELISA method based on the monoclonal antibody of σA protein was successfully established for the identification and detection of ARV,which provided a technical means for the accurate and rapid detection of ARV.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

  Objective  To analyze the current status of the development of adaptation guidelines in China, as well as their methodological quality and the reporting quality, in order to provide reference for the development of adaptation guidelines.  Methods  We searched and collected adaptation guidelines led by Chinese researchers or institutions from 2015 to 2023 from four electronic databases, China National Knowledge Infrastructure, WanFang Data Knowledge Service Platform, SinoMed and PubMed, extracted the basic information of the adapted guidelines, and assessed their methodological quality and reporting quality using the Appraisal of Guidelines for REsearch and Evaluation (AGREE) Ⅱ and RIGHT-Ad@pt tools.  Results  A total of 14 adaptation guidelines were included, mainly focusing on nursing (42.9%, 6/14), with the most frequently used adaptation method of ADAPTE (71.4%, 10/14), and with reference to pre-existing guidelines mainly from the United States, the United Kingdom, and international organizations. Assessment by the AGREE Ⅱ tool showed that the average methodological quality score of the adapted guidelines was 36.6%. The scores were relatively high in the domains of clarity of expression and rigor of formulation (44.4% and 54.9%), and lowest in the domain of applicability (15.3%). The results of the RIGHT-Ad@pt tool showed that the reporting quality of the adaptation guidelines was relatively good, with the highest reporting rate of 91.2% and the lowest of 35.3%, and the reporting rates of seven articles were higher than 70%.  Conclusions  Adaptation guidelines in China are still in their infancy, with a relatively small number and mainly focusing on the nursing field. The most commonly used adaptation method is the ADAPTE method. The methodological quality and reporting quality of adaptation guidelines need to be further improved, and more research should be conducted on the specific conditions and timing of adaptation guidelines development.
