Primary bronchopulmonary carcinoma occurs in the bronchial mucosa epithelium, also called lung cancer (LC), and has currently become the first cause of death of malignant tumors in China. With constant efforts of Chinese physicians, the diagnosis and management of LC has made certain progress, but standardized surgery for LC still varies to a great extent due to difference regions, nature of medical centers, and technical levels. Complete and standardized surgical resection can provide good long-term survival for patients with stageⅠ, Ⅱand partly ⅢA LC, and cannot be a substitute for other treatment, which shows the importance of standardized surgery. As the most solid member, surgery plays a decisive role in comprehensive multidisciplinary treatment of LC. Today's medical development requires thoracic surgeons to provide most standardized and individualized treatment with principles of evidence-based medicine. This review focuses on progress of standardized surgery for stage Ⅰto ⅢA LC.
Objective Tissue engineering advance in supplying the reparative and reconstructive medicine with promising tissue engineered medical products(TEMPs) and the new therapy alternative. The related supervision and administration of TEMPs is being developed and the standard research of TEMPs is also in progress. The Food and Drug Administration(FDA) of the United States has treated TEMPs as combined products and supervised them according to the level of risk to patients. Lately, FDA has determined that the Center for Devices and Radiological Health (CDRH) should take charge of examination and approval of TEMPs, with the cooperation of the Center for Biological Evaluations and Research(CBER). The regulatory controls have been established respectively in European Union and Japan. In China, TEMPs are identified as medical devices combined with cells. The Department of Medical Device of the State Food and Drug Administration (SFDA) is responsible for the examination and approval of TEMPs, and National Institute for the Control of Pharmaceutical amp; Biological Products(NICPBP) is responsible for evaluation tests. The standards of TEMPs are formulated mainly by the American Society of Testing Materials(ASTM) and International Standardization Organization(ISO).
ObjectiveTo analyze the relationship between maximum standardized uptake value (SUVmax) of primary tumor detected by 18F-FDG positron emission tomography/computed tomography (PET/CT) and clinicopathologic factors in stageⅠnon-small cell lung cancer (NSCLC), and investigate the prognostic value of PET/CT on pathological feature. MethodsWe retrospectively analyzed clinical data of 182 patients with stageⅠNSCLC who underwent 18F-FDG PET/CT scan before lobectomy or segmentectomy in China-Japan Friendship Hospital from April 2013 to June 2014. There were 121 male and 61 female patients with their ages of 34-85 (68.1±9.8) years. Clinicopathologic factors including sex, age, smoking history, histology, TNM stage, T stage, tumor size, lymphatic vessel invasion, blood vessel invasion (BVI) and visceral pleural invasion were evaluated to identify the independent factors affecting SUVmax by univariate and multivariate regression analysis. The diagnostic efficiency and best cut-off point of SUVmax were calculated by the receiver operating characteristic curve. ResultsThe univariate analysis identified that sex (P=0.015), smoking history (P=0.001), histology (P < 0.001), TNM stage (P=0.004), T stage (P=0.001), tumor size (P < 0.001), BVI (P=0.001) were factors affecting SUVmax. Only histology (P=0.001), tumor size (P=0.006), BVI (P=0.009) were found to be significant independent factors according to multivariate regression analysis. The SUVmax of primary tumor was a predictor for BVI with the highest diagnostic accuracy at a cut-off value of 4.85, the sensitivity and specificity were 65.5% and 71.7%. ConclusionThe SUVmax is correlated with histology, tumor size and BVI in stageⅠNSCLC, higher in patients with non-adenocarcinoma, lager tumor and positive BVI. Furthermore, the probability of BVI could be predicted by SUVmax of the primary tumor.
We summarize the primary structure, objective and achievements of the resident standard training program in West China Hospital of Sichuan University during the past decade. We also give some advices on how to develop and accomplish future goals of resident standard training.
ObjectiveTo analyze the value of structured electronic medical records for pulmonary nodules in increasing the ability of outpatient service and hospital management by resident physicians.MethodsWe included 40 trainees [94 males and 26 females aged 22-31 (26.45±2.81) years] who were trained in the standardized training base for surgical residents in our hospital from January 2018 to January 2021. The trainees were randomly divided into two groups including a structured group using the structured electronic medical record for pulmonary nodule and an unstructured group using unstructured electronic medical record designed by our department. The time of completing hospitalization records and first-time course records, the quality of course records, the accuracy of issuing admission orders, the quality of teaching rounds, and patient’s satisfaction between the two groups were analyzed and compared.Results(1) The average time in the structured group to complete inpatient medical records was significantly shorter than that of the unstructured group (53.61±8.12 min vs. 84.25±16.09 min, P<0.010); the average time in the structured group to complete the first-time course record was shorter than that of the unstructured group (13.20±5.43 min vs. 27.51±8.62 min, P<0.010), and there was a significant statistical difference between the two groups. (2) The overall teaching round quality score of the students in the structured group was significantly higher than that in the unstructured group (84.21±15.61 vs. 70.91±12.28, P<0.010). (3) The score of the medical record writing quality of the structured group was significantly higher than that of the unstructured group (80.25±9.22 vs. 74.22±5.40, P<0.010).ConclusionThe structured electronic medical record specific for pulmonary nodules can effectively improve the training efficiency in the standardized training of surgical residents, improve the clinical ability to deal with pulmonary nodules, improve the integrity and accuracy of key clinical data collected by students, and improve doctor-patient relationship.
Currently, there is a lack of clarity and standardization regarding the implementation details of interventions in traditional Chinese medicine clinical practice guidelines (CPGs). This in methodological guidance for standardizing the implementation prescription adversely impacts the quality of implementation and hinders the clinical application rate of recommendations. Through in-depth analysis of implementation prescription of evidence-based CPGs in traditional Chinese medicine, we identified the challenges associated with standardization. In response, we propose enhancing the technical specifications of implementation prescriptions, advocating for improved formulation processes, diverse reporting approaches, and standardizedological guidelines. These recommendations aim to serve as a methodological reference and guidance for clinical practice guideline developers.
Objective To investigate the status of knowledge, attitude and practice (KAP) of Standard Practice for Intravenous Nursing among nurses. Methods A total of 140 nurses were recruited and investigated with a self-designed questionnaire on March 16th, 2016. Results A total of 140 questionnaires were collected and 137 valid questionnaires were finally analyzed. Nurses’ KAP scores of Standard Practice for Intravenous Nursing were good. Hospital level, hospital characteristics, position and whether the nurses were specialized in intravenous nursing were influencing factors of the scores (P<0.05). Conclusions The general situation of KAP of Standard Practice for Intravenous Nursing is good, but nurses' knowledge on intravenous treatment is rather weak. Nurses should pay more attention to the knowledge of Standard Practice for Intravenous Nursing. Targeted education should be provided for nurses to promote the formation of positive attitude and healthy behaviors of clinical intravenous nursing practice.
The American Thoracic Society Committee Task Force on Standards for Pulmonary Function had recommended a standardized reporting format for pulmonary function tests due to considerable variability in pulmonary function reports presented to end users, which might lead to potential confusion and miscommunication. This recommendation includes seven parts: overview, introduction, methods, report format, selecting and reporting reference values, grading the quality of pulmonary function tests and conclusions. This document presents a reporting format in test-specific units for spirometry, lung volumes, and diffusing capacity that can be assembled into a report appropriate for a laboratory’s practice. Recommended reference sources are updated, with especially emphasizing to adapt lower limit of normal (LLN) or z score instead of percent of prediction to estimate the abnormal results. This document provides detail and clear explanation on the recommendations, which might improve the interpretation, communication, and understanding of test results. However, parts of recommendation might not be used directly in our clinical practice owing to some specific conditions in China. We suggest to use appropriate normal predictions from Chinese population, to include small airway parameters such as mid-maximal expiratory flow for early detection of pulmonary function deterioration, and to include inspiratory flow volume curve, as well as strengthen the quality control data and figures in the report format.
ObjectiveTo develop a standardized dataset for adverse drug reactions (ADR) of Chinese herbal formula granules (CHFG) to regulate the collection content of ADR, promote the standardization and normalization of ADR data collection for CHFG, and facilitate the sharing, integration, and analysis of adverse reaction data. MethodsWe used a combination of literature research, Delphi survey and consensus meeting. ResultsA Delphi survey questionnaire was constructed based on the results of literature research, including 6 domains and 76 items. After the Delphi survey and consensus meeting, a final CHFG adverse reaction dataset was developed, including 6 domains and 75 items. The six domains were patient details, suspected drugs, other treatments/concomitant medications, detailed information on the suspected adverse reaction, possible influencing factors (causes of the suspected adverse reaction), and details of the person reporting the suspected adverse reaction. Compared with the data collected by the National Adverse Drug Reaction Monitoring Center, this dataset introduced a new domain called "Possible influencing factors", which included several items such as irrational use of CHFG, toxic varieties of Chinese herbal medicine, storage and usage conditions, physical characteristics, processing methods, and patient diet. It also contained the information on Chinese medicine syndromes and other herbs in the prescription, and modified multiple items based on the particularities of formula granules. ConclusionThe development and application of this standardized dataset of ADR for CHFG can facilitate data collection, integration, and analysis, furthermore improve doctors' awareness of prescribing safely and enhance patient medication safety.
ObjectiveTo summary the standard treatment for early gastric cancer. MethodsThe current early gastric cancer treatment guidelines around the world were analyzed and the standardized treatment patterns for early gastric cancer were concluded. ResultsThe accurate preoperative evaluation for early gastric cancer is the basis of standardized treatment which can be divided into staging evaluation and histological evaluation.The staging evaluation is focused on the gastric wall invasion and lymph node involvement of the tumor while the histologic evaluation emphasize the histological type and grading of the tumor.According to the precise evaluation for early gastric cancer, endoscopic surgery, laparoscopic surgery, open surgery, and multimodal therapy can be applied individually to the patients.Different treatment methods have their indications, but the indications of the therapies in different guidelines are suggested with slight differences. ConclusionIn clinical practice, the choice of treatment should be made with comprehensive consideration of diagnosis and individual characteristics of patients to achieve the most benefit on prognosis.
