The Hazardous Drug Exposure Management: Information for Healthcare Settings (2023 Edition) released by the National Institute for Occupational Safety and Health (NIOSH) of US provided detailed protection recommendations for medical personnel to mitigate the risks of occupational exposure to hazardous drugs. This study reviewed the literature in terms of hazard identification, occupational exposure assessment, risk assessment, risk management planning, and waste and spill control. It also explored the precautions for each step of hazardous drug handling, aiming to raise medical personnel's awareness of hazardous drug protection and improve their self-protection skills. The findings provided valuable references for medical institutions to develop hazardous drug disposal plans and reduce employees' exposure to hazardous drugs and occupational injuries.

Objective: To explore the clinical and imaging characteristics of patients with regional odontodysplasia accompanied by hypodontia and to provide a reference for clinical diagnosis and treatment. Methods: This report presents the imaging manifestations, diagnosis, and treatment of a case of regional odontodysplasia (RO) accompanied by hypodontia. It includes a retrospective summary of the dynamic changes in the imaging characteristics of the affected teeth over a 5-year period, along with a comparative analysis of the literature. The patient was a 9-year-old female who presented to the Clinic of Oral Rare and Genetic Diseases of our hospital with the chief complaint of “discomfort for over seven months following the extraction of the teeth in the left mandibular region.” Based on her clinical manifestations and imaging findings, she was diagnosed with RO in the left mandible and with hypodontia of permanent teeth 12 and 34. A treatment plan was formulated, and long-term follow-up was conducted. The current radiographic images were compared with previous imaging data to summarize the developmental changes in her teeth, and a comparative analysis was also performed with the literature to identify similarities and differences with previously reported RO dental characteristics. Results: During the follow-up period, the patient's symptoms did not worsen, and a conservative observation approach was adopted; the treatment plan was decided after the eruption of the affected teeth. By comparing and analyzing imaging data from three ages (4.5, 8.5, and 9 years old), it was determined that the deciduous and permanent teeth in the left mandible of this patient exhibited typical “ghost” radiographic features, alongside hypodontia of teeth 12 and 34, as well as the delayed development of tooth 35. A literature review and analysis indicated that RO manifests clinical characteristics such as delayed tooth eruption, reduced tooth size, and yellow crowns, along with typical “ghost” radiographic appearances. Treatment requires a personalized approach based on the patient’s specific condition. To date, only five cases of RO patients with hypodontia have been reported, while the delayed development of permanent tooth buds has not yet been documented. Conclusion For patients with RO, dynamic imaging evaluation plays a critical role in early diagnosis. RO is associated with hypodontia and delayed tooth germ development. Long-term follow-up and personalized treatment plans are the key to RO treatment.

The operating room is the core settings of various surgical treatments, and exhibits distinct attributes and systemic complexities. Medical staff who work long term in operating rooms face multiple exposures to potential health hazards. Especially with the progress of electrosurgical technology and the frequent use of electrosurgical equipment, the possible health effects of the resulting electrosurgical smoke to those working in operating rooms have gradually attracted attention. This paper reviewed the composition, hazard, exposure risk monitoring, and protective measures of electrosurgical smoke, aiming to deepen the understandings of potential health risks of electrosurgical smoke, improve the self-protection awareness of medical staff, strengthen attention to electrosurgical smoke protection in all hospitals, and ensure the occupational safety of medical staff.

Objective To explore the cost effectiveness of osimertinib and gefitinib in the treatment of advanced non-small cell lung cancer （NSCLC） with epidermal growth factor receptor （EGFR） mutation. Methods A total of 52 advanced NSCLC patients with EGFR mutation treated by osimertinib were selected as group A from June 2021 to August 2022 at the Chengde Central Hospital, and 52 patients treated by gefitinib were selected as group B according to the propensity score matching method in 1∶1 ratio. The treatment cost and effect of the two groups of patients were compared, and the cost-effectiveness ratio was calculated, and sensitivity analysis was conducted. Results The total effective rate of group A was higher than that of group B （90.38% vs 71.15%, χ²=6.190, P=0.013）. The drug cost and total treatment cost of group A were higher than those of group B（P<0.05）, and other direct costs were lower than those of group B （P<0.05）. The incremental cost effectiveness ratio of group A was 374.71. After the cost-effectiveness sensitivity analysis on adjusting drug costs to decrease by 10% and the total effective rate to decrease by 10% of the two groups, the sensitivity analysis results were basically consistent with the original results. Conclusion Based on the latest prices and actual case data of osimertinib and gefitinib, osimertinib was better than gefitinib in the treatment of advanced NSCLC patients with EGFR mutation. Although gefitinib had lower treatment costs, osimertinib had more cost effectiveness advantages. These findings could provide important reference for the clinical development of treatment plans for advanced NSCLC patients with EGFR mutations.

OBJECTIVE To provide a reference for clinically rational drug use and pharmaceutical care for patients with diabetes complicated with hyperlipidemia induced by immunosuppressive agents after liver transplantation. METHODS Clinical pharmacists participated in the treatment of a patient with diabetes complicated with suspected hyperlipidemia induced by immunosuppressive agents after liver transplantation. Due to the poor glucose control of the patient， the clinical pharmacists assisted the doctor in adjusting the glycemic control plan： subcutaneous injection of 18， 12 and 16 units of Insulin lispro injection before meals， and subcutaneous injection of 16 units of Insulin glargine injection before bedtime. Due to the occurrence of hyperlipidemia in the patient， clinical pharmacists clarified the possible cause of abnormal blood lipid elevation was using immunosuppressants by reviewing the timeline of dose adjustment of immunosuppressive agents and changes in blood lipid levels based on relevant guidelines. Clinical pharmacists suggested using Rosuvastatin calcium tablets 5 mg， qd for lipid-lowering treatment， reducing the dosage of Mycophenolate mofetil capsules and Tacrolimus capsules to 500 mg， bid and 2 mg， bid， respectively. Medication education and pharmaceutical care were also carried out. RESULTS The doctor adopted the advice of the clinical pharmacists. After treatment， the levels of blood glucose and blood lipid in the patient improved， and he was allowed to be discharged with medication. CONCLUSIONS Clinical pharmacists provide pharmaceutical services such as recommending the addition of statins， adjusting the dosage of immunosuppressive agents， and conducting pharmaceutical care to optimize individualized medication plans for patients and ensure the safety and effectiveness of medication.

OBJECTIVE To establish the analysis methods of 33 banned pesticides in Ginkgo Biloba leaves and the extracts, and conduct the risk assessment study. METHODS One hundred and thirty-six batches of Ginkgo Biloba leaves and 58 batches of Ginkgo Biloba leaves extract were detected by UPLC-MS and GC-MS. The acute and chronic intake risk of pesticide residues in samples were calculated by point assessment method, and the risk scores of the pesticides were calculated by the Britain veterinary residues matrix ranking. RESULTS Six kinds of banned pesticides were detected in 136 batches of Ginkgo Biloba leaves, the total detection rate was 35.29%, and the detection amount was 0.002−0.210 mg·kg−1. The chronic dietary intake risk was 0.018%−0.620%, and the acute dietary intake risk was 0.000 1%−0.014 0%, indicated that the dietary exposure risk of pesticides in Ginkgo biloba leaves was at a low level. Two kinds of banned pesticides were detected in 58 batches of Ginkgo Biloba leaves extract, the detection rate was 55.17%, and the detection amount was 0.002−1.788 mg·kg−1. The percentage of acceptable daily intake was 0.003%−0.143%, and the percentage of acute reference dose was 0.002 4%, which was also at a low level. Risk ranking results indicated that the risk of phorate was the highest and should be focused on the production and safety supervision. CONCLUSION The method has good stability, high precision and promising repeatability, which can be used for the detection of 33 prohibited pesticides in Ginkgo biloba leaves and their extracts. The results show that the residual amounts of 33 banned pesticides in Ginkgo Biloba leaves and its extracts were extremely low, and there is no significant health risks.

Pain is one of the most common symptoms in cancer patients. Apart from causing patients to suffer from unpleasant feelings and negative emotional experiences, uncontrolled pain may also influence patients' function and quality of life, and may be associated with poorer prognosis. Poor management of chronic cancer-related pain may be related to its complicated mechanisms, limitations of current clinical treatment and clinicians' and patients' insufficient understanding of the symptom. Therefore, this review summarizes the definitions, classifications, evaluation and treatment principles of chronic cancer-related pain, and emphasises the importance of multidisciplinary management and patient education in cancer pain management to provide clinicians with the overall idea of pain management in adult cancer patients.

Objective To assess the effectiveness of Healthcare Failure Mode and Effect Analysis(HFMEA)in the intravenous thrombolysis process for patients with Acute Ischemic Stroke(AIS).Methods The targeted and comprehensive emergency care plan was constructed using HFMEA methodology.This plan was then applied to optimize the intravenous thrombolysis process in the target hospitals.Key indicators were evaluated before and after the intervention using t-tests,chi-square tests,and non-parametric tests.Results After the implementation of HFMEA,the mean Risk Priority Number value for the intravenous thrombolysis process in AIS decreased compared to before implementation.Additionally,the rate of intravenous thrombolysis within 4.5 hours of onset increased to 54％.The HFMEA model management group showed an 8％improvement compared to the conventional management group.The median time between patient admission and the start of intravenous thrombolysis door to needle time(DNT)was shorter,hospitalisation costs were lower,and National Institutes of Health Stroke Scale scores were reduced at 1 and 2 weeks post-treatment,as well as at discharge.However,there was no significant difference in the number of hospital days between the two groups.Conclusion The use of HFMEA management tools can effectively improve the intravenous thrombolysis process in patients with AIS.This can increase the rate of reperfusion therapy in AIS,shorten the time to DNT,and improve early neurological function.Additionally,it can promote patient health and reduce the burden on families.

Objective To preliminarily analyze the influencing factors of benign thyroid nodule malignant transformation and provide a basis for early intervention of benign thyroid nodule malignant transformation. Methods Selected 158 patients with benign thyroid nodules who visited our hospital from January 2019 to January 2022 for inclusion in the study, and followed up for 3 year to observe whether the nodules had malignant changes. The age, gender and dietary habits were collected. 3 mL of fasting venous blood of subject were collected , and the level of TT3, TT4, FT3, FT4, TSH, TgAb, CEA, thyroglobulin and calcitonin were collected. Results The results of this study suggest that the plasma levels of serum TgAb, TSH, TT4, TT3, FT3, FT4, CEA, thyroglobulin, and calcitonin of subjects were not statistically significant between sexes. The results of univariate analysis showed that compared with non malignant group, the patients in malignant nodule group were younger, the longest diameter of nodule was smaller, TgAb level was higher, TSH level was higher, FT3 level was lower, the proportion of internal calcification was higher, thyroglobulin level was higher, CEA level was higher, calcitonin level was higher, and the proportion of abnormal lipid metabolism and glucose metabolism was also higher, which was statistically significant (P<0.05). Multivariate logistic regression analysis showed that TgAb positive, internal calcification, increased carcinoembryonic antigen level, dyslipidemia, elevated thyroglobulin level, and abnormal glucose metabolism, elevated calcitonin level were associated with the increased risk of node canceration, and increased total FT3 level was associated with the reduced risk of canceration (P<0.05). Conclusion TgAb positive, internal calcification, increased carcinoembryonic antigen level, small nodule diameter, abnormal blood lipids, elevated thyroglobulin level, low total FT3 level, abnormal glucose metabolism, and elevated calcitonin level are associated with the increased risk of malignant transformation of benign thyroid nodules, which should be paid attention to clinically.
