Computer and Internet become a great threat to personal privacy. The paper introduces several forms of how computer and Internet threaten personal privacy, such as drive-by installation, webbug, electronic payment mechanism, as well as other computer or network application with potential privacy destruction, and provides some policies for protecting privacy, including improving legal system, applying websites privacy seal, etc.

Objective To explore the effect of implementation of prevention and control measures on reducing the incidence of multidrug-resistant organisms(MDROs)healthcare-associated infection(HAI)rate.Methods Imple-mentation of prevention and control measures on MDROs were strengthened in a hospital in 2012,the relationship between implementation status and change in MDROs infection in the whole hospital were analyzed statistically. Results Through continuous monitoring and tracking,the implementation of prevention and control measures on MDROs continued to be improved,MDRO HAI rate of the second half year was significantly lower than the first half year ([0.29%,119/41 579]vs[0.49%,186/38 252])(χ2 =20.95,P <0.01).Conclusion Continuous monito-ring and tracking of MDROs is helpful for implementing the prevention and control measures on MDROs infection, as well as reducing the incidence of HAI caused by MDROs .

[Objective] : To improve the accuracy and professionalism of question-answering (QA) model in traditional Chinese medicine (TCM) lung cancer by integrating large language models with structured knowledge graphs using the knowledge graph (KG) to text-enhanced retrieval-augmented generation (KG2TRAG) method. [Methods] : The TCM lung cancer model (TCMLCM) was constructed by fine-tuning ChatGLM2-6B on the specialized datasets Tianchi TCM, HuangDi, and ShenNong-TCM-Dataset, as well as a TCM lung cancer KG. The KG2TRAG method was applied to enhance the knowledge retrieval, which can convert KG triples into natural language text via ChatGPT-aided linearization, leveraging large language models (LLMs) for context-aware reasoning. For a comprehensive comparison, MedicalGPT, HuatuoGPT, and BenTsao were selected as the baseline models. Performance was evaluated using bilingual evaluation understudy (BLEU), recall-oriented understudy for gisting evaluation (ROUGE), accuracy, and the domain-specific TCM-LCEval metrics, with validation from TCM oncology experts assessing answer accuracy, professionalism, and usability. [Results] : The TCMLCM model achieved the optimal performance across all metrics, including a BLEU score of 32.15%, ROUGE-L of 59.08%, and an accuracy rate of 79.68%. Notably, in the TCM-LCEval assessment specific to the field of TCM, its performance was 3% − 12% higher than that of the baseline model. Expert evaluations highlighted superior performance in accuracy and professionalism. [Conclusion] TCMLCM can provide an innovative solution for TCM lung cancer QA, demonstrating the feasibility of integrating structured KGs with LLMs. This work advances intelligent TCM healthcare tools and lays a foundation for future AI-driven applications in traditional medicine.
