    The simplified model for parameter σwi in the model of Formula
    (18) can be obtained through parameter simplification process, in the form of: 
    In the formula, the parameter item m0 is the mean value ob-tained from the diagonal Exendin 4 of the matrix, and the parameter item m1 is the mean value obtained from the diagonal element of ∑ i. The specific form of improvement algorithm is shown Algo-rithm 1:

    During the construction of Bayesian geometry reconstruction model for the use analysis of anesthetic analgesic drugs in cancer patients above, because there are two loops nested, the compu-tational complexity of the algorithm can be analyzed according to these two nested loops. The computational complexity of the first loop is 1: L and that of the latter is 1: K. Therefore, the computational complexity of the outer loop is O (4L × K ), and that
    4.1. Type analysis of anesthetic analgesic drugs used in patients
    Seven kinds of anesthetic analgesic drugs were used in pa-tient with cancer pains, including three kinds of injection and tablets and one kind of patch. Three kinds of injection include Mor-phine Hydrochloride Injection, Tramadol Injection and Dezocine Injection; the tablets include Morphine Hydrochloride Sustained-release Tablets, Tramadol Hydrochloride Sustained-release Tablets and Oxycodone Hydrochloride Sustained-release Tablets; and the patch is Fentanyl Transparent Dressing.
    4.2. Dosage and relevant specification analysis of anesthetic analgesic drugs
    In the anesthetic analgesic drugs used by patients with cancer pains, the dosage of Morphine Hydrochloride Sustained-release Tablets is the highest, followed by Tramadol Hydrochloride Sustained-release Tablets, Oxycodone Hydrochloride Sustained-release Tablets, Fentanyl Transparent Dressing, Morphine 
    Hydrochloride Injection, Tramadol Injection and Dezocine Injec-tion, as shown in Table 1 in details.
    4.3. Use analysis of anesthetic analgesic drugs in patients with cancer pains
    In the anesthetic analgesic drugs used by patients with can-cer pains, the defined daily dosage (DDD) of Fentanyl Transpar-ent Dressing is the highest, followed by Morphine Hydrochloride Sustained-release Tablets, Morphine Hydrochloride Injection, Oxy-codone Hydrochloride Sustained-release Tablets, Tramadol Hy-drochloride Sustained-release Tablets and Tramadol Injection, Constitutive heterochromatin of Dezocine Injection is the lowest. The drug utilization index of Oxycodone Hydrochloride Sustained-release Tablets is the lowest, followed by Dezocine Injection, Tramadol Hydrochloride Sustained-release Tablets, Tramadol Injection, Morphine Hydrochloride Injection and Fentanyl Transparent Dressing, that of Morphine Hydrochloride Sustained-release Tablets is the highest. See details in Table 2:
    5. Conclusion
    As a common symptom of advanced cancer patients, cancer pain is an important and difficult problem in preoral clinical pain research. Cancer pain will not only affect the effect of clinical treat-ment, but also reduce the survival quality of patients. Therefore, relieving the pains of patients becomes the key focus in the clinical. In recent years, the incidence of cancer in China has been increasing year by year, and the use of anesthetic analgesic drugs to a large extent alleviates the pain of patients and improves the survival life of patients. In anesthesia and analgesia of cancer pain, the basic principles of cancer treatment shall be complied with: oral admin-istration, timely administration, ladder administration, individual-ized administration and attention to details. It is shown from the related data that the dosage and the amount of anesthetic analgesic drugs used for cancer pain are increasing year by year due to the increase of cancer incidence and the change of doctor’s concept of drug use. In the clinical treatment of patients with preoral cancer pain, the anesthetic drugs are widely used; including a variety of anesthetic analgesic drugs, to a large extent alleviating the pain of patients. The key clinical focus is to comply with the clinical use principle of anesthetic drugs, improve the anesthetic and analgesic effect, avoid drug dependence and addictive symptoms of patients and conform to the three-step principle of cancer pain of WHO.
