OBJECTIVE:To investigate the situation of pharmacoeconomic researches about lipid-lowering drugs in China, and to seek the regimen with good cost-effectiveness in order to provide reference for rational drug use in the clinic. METHODS:Retrieved from CNKI and Wanfang database,pharmacoeconomic literatures about lipid-lowering drugs,published in domestic jour-nals during 2011-2015,were included to discuss the problems of pharmacoeconomic researches about lipid-lowering drugs and put forward related suggestions. RESULTS:Rosuvastatin and other medicines showed good cost-effectiveness,while there were many problems of domestic published pharmacoeconomic researches about lipid-lowering drugs,such as different research methods,dif-ferent treatment courses,different methods of cost calculation,single effect index and absence of ADR. On the whole,the research-es were low in quality,which led the difficulty of accurately obtaining the drugs with best cost-effectiveness. CONCLUSIONS:In the future,related researches should confirm research duration and health output index,effect index and evaluation method accord-ing to disease types and research objectives;enhance the unity of research and design methods;pay attention to cost discount;in addition,strengthen pharmacoeconomic researches about lipid-lowering TCM and compare it with chemical drugs.

Objective To identify the imaging features of pancreatic acinar cell carcinomas.Methods Eleven patients of pancreatic acinar cell carcinomas proven surgically and pathologically were included.We retrospectively evaluated the CT and MR findings including the location, size, shape, margin, necrosis , calcification, hemorrhage, enhancement degree, enhancement pattern, invasion to other organs, perilesional lymph nodes, metastasis, recurrence.Results The tumors were distributed in the head(n=4), body and tail(n=4),tail(n=3) of pancreas.The median tumor size was 97 mm(27 to 180 mm).Nine cases presented with a well-defined enhancing capsule.Tumor vessels could be seen in 9 cases.Seven cases were hypovascular while the other 4 were hypervascular.Different extents of necrosis could be seen in all masses as a swirling or cleft low density in the enhanced tumors, with an median of 10％ (2％ to 25％).The hypovascular masses more frequently demonstrated a lobulated tumor, heterogeneous enhancement pattern, with a larger necrotic component and were more common invasion to other organs.Conclusions Pancreatic acinar ccll carcinoma typically presents as a sizable pancreatic mass with a well-defined enhancing capsule.

Objective To clinically verify the rationality of evaluation standard of oropharynx involvement in the Chinese 2008 staging system for nasopharyngeal carcinoma (NPC).Methods 333 consecutive patients with newly diagnosed,untreated,and nonmetastatic NPC were included.All patients had an MRI examnation of the nasopharynx and neck.The status of oropharynx involvement were evaluated.Results Of the 333 patients with NPC,26 (7.8 ％) patients presented with oropharynx involvement.Tumor invasion into oropharynx was highly related to tumor invasion into nasal cavity,parapharyngeal space,skull base,medial pterygoid muscle,paranasal sinuses,intracalvarium and masticator space excluding medial pterygoid muscle (P ＜ 0.050).The oropharynx involvement was associated with poorer 5-year overall survival (OS) and distant failure-free survival (DFFS) (38.1％ vs 72.6 ％,P＜ 0.001 and 49.1％ vs 84.5 ％,P＜ 0.001,respectively).By multivariate analyze,it was observed that oropharynx involvement was a significant predictive factor for OS and DFFS (P ＜ 0.001,P ＜ 0.001).Significant differences were observed in the 5-year OS (38.1％ vs 80.9 ％,P ＜ 0.001) and DFFS rates (49.1％ vs 89.3 ％,P ＜ 0.001) between the patients with oropharynx involvement and stage T2 patients.Conclusions MRI-evidenced oropharynx involvement had a negative impact on OS and DFFS in NPC patients.The oropharynx involvement is associated with poorer 5-year OS and DFFS compared with stage T2.The evaluation standard of oropharynx involvement for NPC in the Chinese 2008 staging system could be revised.

Accurately assessing and positioning the current development status of disciplines can help hospitals formulate targeted disciplinary development strategies and achieve disciplinary development goals. In 2022, a large tertiary public hospital established a discipline-demand-oriented " pyramid" hierarchical discipline evaluation system based on Maslow′s need-hierarchy theory. The discipline evaluation system set six levels of evaluation indicators from low to high, including medical quality and safety, department operation, sub specialty construction, scientific and educational achievements, platform construction, and talent cultivation(including 6 primary indicators, 21 secondary indicators, and 44 tertiary indicators). By applying the evaluation system and providing feedback on the evaluation results in the form of " disciplinary diagnostic reports" and " disciplinary evaluation conferences, " the hospital′s discipline construction had been improved at six levels. From 2022 to 2023, the hospital added five national clinical key specialties; The number of sub major construction disciplines increased from 18 in 2021 to 61 in 2023, and patient satisfaction increased from 94.64% to 96.25%. This evaluation system could objectively reflect the level of discipline development, lead the high-quality development of disciplines, and provide references for other public hospitals to promote discipline development.

Objective:To explore the safety and clinical value of ultrasound-guided percutaneous core needle biopsy in the diagnosis of cardiac intermural tumors and pericardial tumors.Methods:Seven patients who underwent ultrasound-guided percutaneous cardiac tumors needle biopsy in Fujian Provincial Hospital from January 2012 to December 2019 were selected for this study. The locations and sizes of the lesions were recorded preoperatively by echocardiography and the operation time was recorded by conventional ultrasonography. The postoperative complications was followed up, and the satisfaction of pathological materials was used as the evaluation standard to comprehensively analyze the safety and clinical application value of ultrasound-guided percutaneous biopsy in the diagnosis of cardiac tumors.Results:Ultrasound-guided percutaneous biopsy was performed successfully in all the 7 cases, 3 of them were intermural tumors and 4 of them were pericardial tumors. Except for 2 patients with diffuse pericardial space, the maximum diameter of the remaining 5 patients was (58.6±23.5)mm. Six cases were punctured from the apex of the heart, and 1 case from the left parasternal through third intercostal space toward the bottom of the heart as the needle pathway. The satisfaction of pathological material was 100%, and the time of procedure was (15.1±3.3)min. There were no postoperative complications such as bleeding, infection or arrhythmia.Conclusions:Ultrasound-guided percutaneous transthoracic needle biopsy is safe and feasible, which provides a simple and easy method for the biopsy of cardiac intramural tumors and pericardial tumors.
