BACKGROUND Schizophrenia is a psychiatric disorder characterized by chronic or recurrent symptoms.Lurasidone was licensed in China in 2019 for the treatment of adult schizophrenia in adults with a maximum dose of 80 mg/d.However,post-market surveillance(PMS)with an adequate sample size is required for further validation of the drug’s safety profile and effectiveness.AIM To conduct PMS in real-world clinical settings and evaluate the safety and effectiveness of lurasidone in the Chinese population.METHODS A prospective,multicenter,open-label,12-wk surveillance was conducted in China's Mainland.All patients with schizophrenia from 10 sites who had begun medication with lurasidone between September 2019 and August 2022 were eligible for enrollment.Safety assessments included adverse events(AEs),adverse drug reactions(ADRs),extrapyramidal symptoms(EPS),akathisia,use of EPS drugs,weight gain,and laboratory values as metabolic parameters and the QTc interval.The effectiveness was assessed using the brief psychiatric rating scale(BPRS)from baseline to the end of treatment.RESULTS A total of 965 patients were enrolled in the full analysis set and 894 in the safety set in this interim analysis.The average daily dose was 61.7±19.08 mg(mean±SD)during the treatment.AEs and ADRs were experienced by 101 patients(11.3%)and 78 patients(8.7%),respectively,which were mostly mild.EPS occurred in 25 individuals with a 2.8%incidence,including akathisia in 20 individuals(2.2%).Moreover,59 patients received drugs for treating EPS during the treatment,with an incidence of 6.6%which dropped to 5.4%at the end of the treatment.The average weight change was 0.20±2.36 kg(P=0.01687)with 0.8%of patients showing a weight gain of≥7%at week 12 compared with that at the baseline.The mean values of metabolic parameters and the QTc interval at baseline and week 12 were within normal ranges.The mean changes in total BPRS scores were-8.9±9.76(n=959),-13.5±12.29(n=959),and-16.8±13.97(n=959)after 2/4,6/8,and 12 wk,respectively(P<0.001 for each visit compared with the baseline)using the last-observation-carried-forward method.CONCLUSION The interim analysis of the PMS of adult patients with schizophrenia demonstrate the safety and effectiveness of lurasidone in the Chinese population.No new safety or efficacy concerns were identified. 展开更多

Safety surveillance is considered one of the most important factors in many constructing industries for green internet of things(IoT)applications.However,traditional safety monitoring methods require a lot of labor source.In this paper,we propose intelligent safety surveillance(ISS)method using a convolutional neural network(CNN),which is an autosupervised method to detect workers whether or not wearing helmets.First,to train the CNN-based ISS model,the labeled datasets mainly come from two aspects:1)our labeled datasets with the full labeled on both helmet and pedestrian;2)public labeled datasets with the parts labeled either on the helmet or pedestrian.To fully take advantage of all datasets,we redesign CNN structure of network and loss functions based on YOLOv3.Then,we test our proposed ISS method based on the specific detection evaluation metrics.Finally,experimental results are given to show that our proposed ISS method enables the model to fully learn the labeled information from all datasets.When the threshold of intersection over union(IoU)between the predicted box and ground truth is set to 0.5,the average precision of pedestrians and helmets can reach 0.864 and 0.891,respectively. 展开更多

Avian influenza (AI), caused by the influenza A virus, has been a global concern for public health. AI outbreaks not only impact the poultry production, but also give rise to a risk in food safety caused by viral contamination of poultry products in the food supply chain. Distinctions in AI outbreak between strains H5N1 and H7N9 indicate that early detection of the AI virus in poultry is crucial for the effective warning and control of AI to ensure food safety. Therefore, the establishment of a poultry surveillance system for food safety by early detection is urgent and critical. In this article, methods to detect AI virus, including current methods recommended by the World Health Organization (WHO) and the World Organisation for Animal Health (Office International des Epizooties, OIE) and novel techniques not commonly used or commercialized are reviewed and evaluated for feasibility of use in the poultry surveillance system. Conventional methods usually applied for the purpose of AI diagnosis face some practical challenges to establishing a comprehensive poultry surveillance program in the poultry supply chain. Diverse development of new technologies can meet the specific requirements of AI virus detection in various stages or scenarios throughout the poultry supply chain where onsite, rapid and ultrasensitive methods are emphasized. Systematic approaches or integrated methods ought to be employed according to the application scenarios at every stage of the poultry supply chain to prevent AI outbreaks. 展开更多

OBJECTIVE: To systematically examine the postmarketing safety of depside salt injection made from Danshen(Radix Salviae Miltiorrhizae),identifythe potential risk factors, and ensure its clinical safety.METHODS: We examined a comprehensive series of studies on the production process, quality standards, pharmacology, population pharmacokinetics, and safety evaluation of depside salt injection made from Danshen(Radix Salviae Miltiorrhizae). Data from Ⅰ-Ⅳ clinical drug trials, hospital information systems(HIS), and spontaneous reporting systems(SRS) were also analyzed.RESULTS: The effective components of salvianolic acid salt content reached almost 100%, and the magnesium lithospermate B content reached morethan 80%. The median lethal dose(LD50) calculated by the Bliss method was 1.49 g/kg, with 95%confidence intervals of 1.29-1.72 g/kg. Long-term tests on Beagle dogs indicated that doses of less than 80 mg/kg were safe and doses of 320 mg/kg were toxic. Adverse drug reactions(ADRs) included digestive disorders; drug-induced erythrocyte deformation in lung, liver, spleen, kidney, bone marrow, intestinal mucosa, lymph nodes, and other tissues; megakaryocytes in lung, liver, and spleen resulting from mild hemolysis; and mild hyperplasia in bone marrow hematopoietic tissue. Other studies indicated no irritative effect of the injection on local tissues and blood vessels, and no allergic reactions, erythrocyte coagulation, or hemolysis. SRS data showed that the most common ADRs were headache, head distention, dizziness, facial flushing, skin itching, thrombocytopenia, and the reversibility of elevated Aspartate transaminase. HIS data indicated no damage to renal function from using depside salt injection made from Danshen(Radix Salviae Miltiorrhizae) at a dosage higher than the recommended dose.CONCLUSION: This study analyzes the clinical characteristics of ADRs from depside salt injection made from Danshen(Radix Salviae Miltiorrhizae),and discusses the factors influencing such reactions. It provides scientific reference and recommendations for clinically safe medication of the Danshen injection. 展开更多

OBJECTIVE: To systematically research the postmarketing safety of Dengfeng shenmai injection, identify potential risk factors, and ensure its clinical safety. METHODS: We investigated a comprehensive series of studies on the production process, quality standards, pharmacology, postmarketing clinical studies, and safety evaluation of Shenmai injection, including literature analysis of adverse drug reaction(ADR) case analysis and systematic review. Data from the hospital information system(HIS) and spontaneous reporting system(SRS) were also analyzed. RESULTS: The approximate dosage leading to death in dogs is 45.0-67.5 g raw drug/kg and the toxic reactions are restlessness, skin irritation, salivation, and vomiting. The results of chronic toxicity tests in mice and dogs, and the other tests such as 6-month toxicity, drug safety, genetic toxicity, and reproductive toxicity of rats and dogs, were positive or qualified. Patient ADR history and ADR family history were closely associated with itching based on the data analysis from SRS. There was no damage to renal function from Shenmai injection use at a dosage and a treatment course outside the recommended dosage and treatment course as specified based on data analysis from HIS. The most common ADR from Shenmai injection are difficulty breathing, facial flushing, nausea, vomiting, chest tightness, skin itching, rash, and back pain. CONCLUSION: This study includes complete information on Shenmai injection ADR incidence rate. We found that Shenmai injection is safe and this study can provide clinical, research, and production institutions with an objective, reliable, and scientific basis for use of Shenmai injection. 展开更多

OBJECTIVE: To assess the safety and effectiveness of Dengzhanxixin injection(DZI) extracted from Dengzhanxixin(Herba Erigerontis Breviscapi) and identify its potential risks.METHODS: A series of studies were conducted on the production process, quality standards, and pharmacology. Postmarketing clinical studies and literature reviews including adverse reactions(ADR),adverse events(ADE), case analysis and systematic reviews were also conducted. Data from the hospital information system and spontaneous reporting system were analyzed.RESULTS: The acute toxicity test indicated that the Lethal Dose 50 test( LD 50) dosage was 250 times more than the clinical maximum daily dosage(6mg/kg). In long-term toxicity tests, rats experi-enced renal tubular damage at 480 mg/kg. However, the dose of 120 mg/kg is safe and non-toxic,which is 40 times above the clinical daily maximum. Beagles had increased serum creatinine at160 mg/kg. In a prospective study, 15 962 cases experienced 16 ADR/ADE. The rate of ADR/ADE was0.1002%. ADR symptoms included rash(16.00%),chills(16.00%), and fever(16.00%).CONCLUSION: There is significant evidence that DZI is safe and effective in a clinical setting. 展开更多

OBJECTIVE: To systematically investigate the safety of Xingxue~ Shuxuening injection(SXN) in preand post-marketing, and to ensure clinical drug safety.METHODS: Strict quality control in raw herb selection and production processes was adopted and pharmacology research on SXN was performed by the drug manufacturing company, Heilongjiang ZBD Pharmaceutical Co., Ltd. We systematically reviewed the safety literature of Xingxue~ SXN. Adverse drug reaction(ADR) data of the drug, extracted from Spontaneous Reporting System(SRS), and clinical characters based on 20 hospital information systems(HIS) in China, were analyzed. Large-scale prospective safety monitoring and Risk Minimization Action Plans(Risk MAPs) of Xingxue~SXN were carried out.RESULTS: The quality of SXN was stable and controllable when it was produced. Drug toxicology studies found no effect on rabbits with hemolytic or condensed, local stimulation and muscle stimulation, and no allergic reactions in guinea pigs. The ADRs of Xingxue~ SXN were dizziness, phlebitis,and vomiting based on SRS data. The injection did not conform to instructions in clinical practice when we analyzed HIS database, and patient’s abnormal blood urea nitrogen levels may be related to the drug, when analyzed using the propensity score method. A nested case-control study was designed and performed to analyze the influencing factors of suspected allergic reactions to SXN. The study showed that patients with an allergy history were more prone to allergic reactions(P<0.001),and some medicine combinations could cause allergic reactions.CONCLUSION: These studies have established a body of evidence on Xingxue~ SXN safety, and provide a good model for Chinese medicine injection for clinical safety. The Xingxue~ SXN production process and toxicology research indicate the safety of the injection. However, the use of the injection is not consistent with instructed clinical practice.Xingxue~ SXN causes ADRs perhaps from inappropriate usage or its pharmacological action. This injection needs better Risk MAPs to ensure its clinical safety. 展开更多
