OBJECTIVE To explore the hotspots of aging adaptation of drug package inserts， and to provide evidence for the development of aging adaptation of drug package inserts in China. METHODS The relevant English literature on drug package inserts for the elderly published from 2012 to 2022 was retrieved from Web of Science Core Collection； bibliometric analysis was performed by using VOSviewer and CiteSpace software， to explore research hotspots in this field， and summarize obstacles and solutions for the development of this field. RESULTS & CONCLUSIONS This study collected a total of 335 literature related to the aging adaption of drug package inserts， from 819 research institutions in 51 countries （regions）， involving 2 174 authors. The research development of drug package insert adaptation for the elderly has slowed down in the past decade， and developed countries such as the United States and Japan dominate this field. Authors such as Wolf from Northwestern University in the United States， have the largest number of publications（12 literature）. The research focuses in this field include the risk management of medication for the elderly， the updating of medication information for the elderly in drug package inserts， and the understanding and compliance of the elderly with drug package inserts and their influencing factors. The solutions to related obstacles in the development of aging adaption in drug package inserts include improving the visibility and readability of drug package inserts， filling in the information on elderly medication in drug package inserts， and so on. China can learn from the experiences and methods of other countries， conduct investigations into the influencing factors of elderly package inserts and pharmacokinetic studies based on the characteristics of the Chinese population， and improve the safety of medication for elderly patients in multiple dimensions.

Clinical analysis of 56 cases of occupational pulmonary thesaurosis induced by dust of iron and its compounds / 中国职业医学

Objective: To analyze the clinical characteristics and imaging features of occupational pulmonary thesaurosis induced by dust of iron and its compounds (OPTIDIC). Methods: A total of 230 cases of occupational welder's pneumoconiosis (OWP) patients or observation subjects were selected as the research subjects using the retrospective analysis method. They were diagnosed in four occupational disease diagnosis institutions in Shandong Province from 2010 to 2017. The high kV X-ray chest radiography or chest digital radiograph (hereinafter referred to as X-ray) were re-read to screen OPTIDIC patients. The clinical data of OPTIDIC patients were collected and analyzed. Results: Among the 230 cases, 56 cases were diagnosed as OPTIDIC, accounting for 24.3%. The clinical symptoms of the 56 patients with OPTIDIC were cough, sputum, chest tightness, shortness of breath, and difficulty breathing, while their physical signs were low or coarse breath sounds in lungs and others. Most of the X-ray results showed p shadows or q shadows, accounted for 98.2%, of which p/p shadow and q/q shadow accounted for 62.5%. The result of chest computed tomography (CT) showed diffuse point/round shadow and diffuse glass shadow in OPTIDIC patients. The result of fibro-bronchoscopy showed that a large amount of iron lutein particles was accumulated in macrophages and biopsy of lung showed idiopathic pulmonary hemosiderosis in OPTIDIC patients. Conclusion: The clinical characteristics of OPTIDIC patients showed no different from OWP. However, the result of X-ray of OPTIDIC patients mainly showed small circular shadows, and their CT images mainly showed diffuse point/round shadows or grinding glass shadow, which could be used to the differential diagnosis of OPTIDIC and OWP.

Objective:To investigate the efficacy of microsurgical treatment in cavernous sinus tumors.Methods:The clinical data of 87 patients with cavernous sinus tumor treated by microsurgery from January, 2010 to August, 2019 were analysed retrospectively. The surgical approaches and microsurgical skills for common tumors in Cavernous Sinus region were discussed. The follow-up included outpatient and telephone follow-ups, and the follow-up results were evaluated by KPS score.Results:Among the 87 cases, 57 were totally resected (65.5%), 14 were subtotal resected (16.1%) and 16 were major resected (18.4%). Hospitalisation ranged from 14 to 98 days, with an average of 29 days. Postoperative complications occurred in 30 cases with cranial nerve injury, 2 brain stem injury, 4 postoperative bleeding, 5 cerebrospinal fluid leakage, 4 infection, 1 Pituitary damage and 1 death. Prognosis and follow-up analysis showed 68 cases with KPS>60 and 66 with KPS>80 at 1 month after surgery; 74 with KPS>70 and 72 with KPS>80 at 3 months after surgery; 78 with KPS>80 by 12 months after surgery. During the follow-up period of 6-120 months, 3 cases died. Recurrence: 6 of incomplete resection of meningioma, were in 1-6 years after the surgery, 4 of incomplete resection of schwannoma in 1-8 years, 2 of pituitary adenoma respectively in 13 and 16 months after the surgery. There was no recurrence after reoperation. Two cases of chondrosarcoma, 3 of chordoma and 3 of germinoma were treated with radiotherapy, and during the follow-up, there was no progress of the focus. No tumor progression or recurrence was found in other cases during follow-up.Conclusion:Surgery of cavernous sinus tumor is difficult due to frequent postoperative complications. Reasonable preoperative plan, surgical approach and precise microsurgical techniques are the keys in reduction of postoperative complications and in the improvement of prognosis.

Structural characteristics and catalytic cycle of dihydroorotate dehydrogenase-a review / 生物工程学报

Dihydroorotate dehydrogenase is a flavin-dependent mitochondrial enzyme to catalyze the fourth step of the de novo synthesis of pyrimidine and to oxidize dihydroorotate to orotate. By selectively inhibiting dihydroorotate dehydrogenase, thereby inhibiting pyrimidine synthesis, the enzyme has been developed for the treatment of cancer, autoimmune diseases, bacterial or viral infections, parasitic diseases and so on. The development of inhibitory drugs requires a detailed understanding of the structural characteristics and catalytic cycle mechanism of dihydroorotate dehydrogenase. Therefore, this paper reviews these two aspects, and indicates perspectives of these inhibitors in clinical application.
