Pathology is a subject that studies the etiology,pathogenesis,pathological changes,progression and outcome of diseases.Pathology links the basic research and clinical practice and is an important part of translational medicine.In order to cultivate qualified pathological graduates with solid pathological theories and the abilities of proposing and addressing scientific hypotheses from pathological morphology changes,we employ modularized special training to divide the pathology training courses into morphology learning module,article searching and reading module,project design module,experiment operation module and scientific presentation module.The training contents among these modules are relatively independent but closely connected,and compose a strategy that aims to improve the scientific innovation ability of pathological graduates.

Objective: To investigate the clinicopathological features, special morphologic variants and potential diagnostic traps of classical follicular dendritic cell sarcoma (FDCS). Methods: A total of 25 cases of classical FDCS diagnosed in the First Hospital Affiliated to Army Medical University from 2006 to 2018 were examined by hematoxylin-eosin staining, immunohistochemistry and in situ hybridization for Epstein-Barr virus-encoded mRNA (EBER). Meanwhile, the types and characteristics of the special variants of FDCS were summarized along with those reported in the literature. Results: The age of patients ranged from 23 to 77 years (mean 52 years), the male to female ratio was 1.5, and the maximum diameter of tumor was 1.5 to 20 cm (mean 7.4 cm). Twelve cases (48%) were misdiagnosed at the initial evaluation. Follow-up information was available for 17 patients, and the follow-up time was 5 to 96 months. The propotion of patients having recurrence, metastasis and mortality was 3/17, 5/17 and 2/17, respectively. Microscopically, besides the typical morphology, 10 cases of FDCS showed special histomorphologies and/or structures, including those mimicking lymphoepithelioma-like carcinoma, desmoplastic infiltrating carcinoma, classical Hodgkin′s lymphoma (CHL), anaplastic large cell lymphoma (ALCL) and hemangiopericytoma. These morphologic variants were potential diagnostic pitfalls and warranted attention. Immunohistochemistry showed that more than two markers of follicular dendritic cells (such as CD21, CD23, CD35, etc.) were expressed in cases showing typical morphology and the special variants. All 25 cases were all negative for EBER by in situ hybridization. Conclusions Classical FDCS is rare, besides the typical morphologic features, there are many special variants. In particular, these may be confused with lymphoepithelioma-like carcinoma in the nasopharynx, CHL or ALCL in the mediastinum/lymph node. Awareness of these variants is essential for accurate diagnosis.

In order to identify 35 key work items indicating the workload, difficulty of nursing technology and nursing risk of different wards scientifically, a mathematical model of classification of wards was established by literature review, conference discussions, expert consultation, brainstorming, and field measurement, and information technology as well. On such basis, scores of the wards were calculated, and the total scoring of each ward was ranked from high to low into three categories and six grades. Each grade of wards was assigned with different performance distribution weights. Such a mathematical model for ward categorizing and grading based on HIS system and key item and weights, can monitor ward nursing in real time, and provide nursing administrators at all levels with clinical risk early warning by means of vertical and horizontal comparisons. These administrators can take precautions in time in terms of human resources and materials. Ward categorizing and grading as an indicator for performance distribution ensures the rationality of such distribution, enhances nursing motivation and stabilizes front-line nursing teams in the end.

Objective To retrospectively analyze the implementation of the antimicrobial agents prescription monthly review at the emergency and outpatient departments for the past five years, for evaluation of its action in promoting rational application of antimicrobial drugs. Methods At the baseline investigation stage, 1780 prescriptions on antibiotics in emergency and outpatient department from June 2012 to November 2012 were randomly selected for centralized evaluation. The period of correction and observation falls into two stages. The first stage ranged from December 2012 to February 2015, when the prescription of antibiotics was sampled manually for monthly review. The second stage ranged from March 2015 to June 2017, when a prescription review software for prescription comment was introduced for the sample purpose. The data so acquired were subject to chi-square test and linear regression analysis using Excel 2010 and SPSS 16. 0. Results The rational rate of prescription for antibiotics at the emergency department increased from 80. 56％ of the baseline stage to 99. 47％ of the second stage (166506/167400), scoring a difference of statistical significance (P<0. 001). With intervention of the prescription review software, the percentage of irrational use of antimicrobial agents dropped by 5. 18％ compared to the baseline stage. Conclusions Monthly prescription review on antimicrobial agents at the outpatient and emergency departments could promote the rational use of antimicrobial agents and play an important role in clinical drug safety. Information system and performance assessment contributed to the effect of prescription review.

The gross specimens and tissue slices used for traditional experimental pathology curriculum are fragile, and some specimens or slices are difficult to be supplemented. Besides, the classroom and schedule for experimental pathology teaching are inflexible. Therefore, the teaching effects for experimental pathology course are limited. The development of digital technology has promoted the teaching reform of medical experimental curriculum. We have digitalized the gross specimens and tissue slices to preserve and expand the samples, and constructed pathological sample repository containing both physical samples and digital samples. Furthermore, we have established a platform for remote access, and thus improved the flexibility and autonomy of study for experimental pathology curriculum. Additionally, we have integrated clinical information of the teaching samples, and interpreted the specimens with the assistance of two-dimensional code technology and voice broadcast technology, to realize human-computer interactive learning. The questionnaire shows that the application of pathological sample repository in experimental teaching has improved student learning effect and recognition.

Pathological specimen sampling is not only the prerequisite of a good pathological diagnosis, but also the primary clinical skill that must be mastered by the standardized residency training trainees (resident trainees) in clinical pathology department. In view of the problems and difficulties encountered in the teaching of specimen sampling, through five years of exploration and attempt, this paper has gradually established a new model with five basic elements, including theory teaching, practice teaching, promoting teaching effect by examination, learning from senior students, and review teaching. The results of evaluation analysis and questionnaire survey show that the teaching mode can make the trainees master the methods of specimen sampling quickly and efficiently, learn and improve clinical skills in practice, and lay a solid foundation for the subsequent standardized training of histopathological diagnosis.

To meet the requirement of pathological practice and development, we systematically analyzed the situation of pathological residents training and the importance of initiating the clinical scientific research training. Additionally, we proposed the principle and implementation strategy for clinical scientific research training. According to features of pathological practice, we employed the modularized teaching to divide the training courses into several modules: discussion module for clinical pathology, lecture module for advanced research, and training modules for basic scientific theory, technology and writing skill. With these approaches, the systematic and structured system of standardized residents training is implemented to improve the clinical research ability of pathological residents.
