Observation of Efficacy of Internet-Based Chronic Disease Management Model Combined with Modified Therapy of Bushenyiliu Decoction in Treating Patients with Type 2 Diabetes Mellitus and Prostate Cancer and Its Effect on Disease Control Rate

Objective To explore the efficacy of Internet-based chronic disease management model combined with the modified therapy of Bushenyiliu decoction in treating patients with type 2 diabetes mellitus (T2DM) and prostate cancer and its effect on disease control rate (DCR). Methods 120 patients with T2DM and prostate cancer admitted to the Affiliated Hospital of Yangzhou University, Yangzhou First People's Hospital, from February 2019 to February 2020, were retrospectively analyzed and equally divided into the experimental group and the control group according to their admission order. Conventional treatment combined with the modified therapy of Bushenyiliu decoction was performed on all patients for 3 months, and the Internet-based chronic disease management model was adopted for patients in the experimental group additionally, so as to compare their short-term effect, survival time, disease progression, blood glucose indicators, immune function indicators, and type 2 Diabetes Self-Care Scale (2-DSCS) scores. Results Compared with the control group, the experimental group obtained significantly higher DCR and objective remission rate (ORR) (P < 0.05), higher survival time and disease progression (P < 0.001), better blood glucose indicators and immune function indicators (P < 0.001), and higher 2-DSCS scores (P < 0.001) after treatment. Conclusion Combining the Internet-based chronic disease management model with the modified therapy of Bushenyiliu decoction can effectively enhance the self-care ability of patients with T2DM and prostate cancer, improve their blood glucose level, promote their body immunity, and comprehensively optimize the cancer control effect, which should be promoted in practice.

agnosis rate has not been significantly improved, and patients are mostly in the metastatic or advanced stage when diagnosed. e role of radical surgery, chemotherapy, and endocrine therapy is limited, and treatment methods such as chemotherapy, like a double-edged sword, will greatly reduce the patients' body immunity, so screening a treatment method that is safer and highly effective has become a research hotspot in the field of prostate cancer treatment.
Recent clinical experiments have confirmed the unique advantages of traditional Chinese medicine (TCM) holism and the therapy with syndrome differentiation in treating the malignant tumors, and both Bushenyiqi decoction and Fuzhengyiliu decoction can improve the functional status of prostate cancer patients [8,9]. e latest studies have shown that Bushenyiqi decoction can affect the Notch signaling pathway and regulate PC-3 cells [10], which has a precise efficacy and higher safety, indicating that TCM treatment is able to enhance the disease control effect of patients. However, clinical experiments usually focus on the treatment of the prostate and ignore the multiple complications that may exist in patients with prostate cancer, and the influence of different complications on the efficacy of TCM treatment is not clear. Type 2 diabetes mellitus (T2DM) is one of the most common complications of prostate cancer, and there are mixed opinions among academia regarding whether the disease is a risk factor predisposing to prostate cancer, but most of the literature have identified that T2DM is closely related to the prognosis of prostate cancer patients [11]. Bjornsdottir and other scholars suggested that T2DM can increase the mortality rate of prostate cancer patients [12], and the levels of blood glucose and glycosylated hemoglobin (HbA1c) can affect the division and apoptosis of prostate cancer cells, so the control of blood glucose level is the focus of treatment for patients with prostate cancer and T2DM. e World Health Organization (WHO) proposes that chronic disease management is a cosmopolitan conundrum [13], and even in Shanghai, where the level of selfcare is high, the rate of blood glucose achievement is still under 10%. Some scholars have shown that the "Internet Plus" chronic disease management model based on mobile communication technology can improve the blood glucose control effect and enhance the patients' treatment compliance [14], which may work in both T2DM and prostate cancer at the same time.
Hence, 120 patients with T2DM and prostate cancer were included in the study to explore the efficacy of combining Internet-based chronic disease management model with the modified therapy of Bushenyiliu decoction in treating patients with T2DM and prostate cancer was explored herein, with the study reported as follows.

1.6. Methods. All patients accepted the conventional treatment combined with the modified therapy of Bushenyiliu decoction for three months. (1) ① Prostate cancer treatment: the total androgen deprivation therapy was adopted, intermittent endocrine blockade was performed after maximum androgen blockade, bilateral orchidectomy was conducted, and 250 mg of flutamide (manufactured: Jiangsu Tasly Diyi Pharmaceutical Co., Ltd.; NMPA approval no. H19990144) was taken after three meals every day; if the patients presented painful bone metastases, zoledronic acid (manufactured: Yangtze River Pharmaceutical (Group) Co., Ltd.; NMPA approval no. H20041975) was added; the chemotherapy project was intravenous infusion of 75 mg/m 2 of docetaxel (manufactured: Yangtze River Pharmaceutical (Group) Co., Ltd.; NMPA approval no.

(1) Designing the chronic disease online management miniprogram: e Wechat miniprogram was developed by personnel from a software development company jointly with our hospital, which included the backstage management side and the patient side, being used by the medical workers and patients as well as their family members, respectively. (2) Building a chronic disease online management team: e team that included 2 endocrinologists, 2 prostate cancer physicians, 4 diabetes specialist nurses, 4 prostate cancer specialist nurses, and 2 nutritionists established a one-to-many management model with the patients, accepted the miniprogram training before the study, joined the theoretical examination and operational examination after training, and obtained the access to the backstage management side after getting the qualification certificate. (3) On the day of patients being enrolled in the experimental group, rehabilitation plans were proposed according to their actual condition, diagnosis, treatment, diet, and exercise plans with individual differences were made, one-to-one training was conducted aiming at the chemotherapy and insulin injection for patients, and then the team helped the patients to join the Wechat group, follow the Wechat miniprogram, and use the miniprogram correctly, to improve the utilization rate of the management platform. (4) Chronic disease online management miniprogram module: ① Electronic health records: e patients filled in the electronic health record that was updated once every two weeks with their basic information including blood pressure, blood glucose, weight, cancer stage, family history, and prior history, the system intelligently identified the health status of the patients and emphatically monitored their blood glucose values, hepatic and kidney function, etc., and then the physicians of the platform reminded the patients of physical examination and urged the patients to upload data, so as to dynamically monitor their condition changes in real time; the miniprogram could analyze the data sent by patients each time and reminded the patients with the risk of the deterioration of disease and at the same time sent message to the physicians of the platform; then the physicians gave proper advice and guidance to patients so that they could understand their own condition changes. ② Health consultation: the medical workers established the disease symptoms database for patients to do the self-service enquiry and find correspondent medical advice; in case the database could not satisfy the patient needs, the patients could enter the interface of physician service and raise questions, which the physicians needed to reply within 2 days. ③ Lifestyle assessment: it included the patients' dietary habits, exercise habits, and occupational habits, and by referring to the functional software such as Boohee, the miniprogram could help the patients record their daily diet and exercise and self-screen their health status with the authoritative scales confirmed by international literature and automatically mark the patients with poor scale scores as the key intervention object; then the physicians pointed out their health risks in life and provided reasonable advice and guidance. ④ Sign-in: the sign-in module was based on the calendar and recorded the dates of logging in the miniprogram, return visits, and blood pressure recording, etc. of patients; the miniprogram pushed the sign-in reminder at 9 pm every day to the patients who did not record the information on time. ⑤ Health education: the knowledge resources about disease prevention and treatment were integrated according to the characteristics of diabetes and prostate cancer; information in popular and easy-to-understand language was screened from newspapers and scientific articles and pushed to Wechat in the form of articles, pictures, and short videos, so as to promote the patients' passive reading volume and increase their health knowledge. (5) All patients constantly recorded their data on the miniprogram and accepted telephone follow-up and clinical follow-up for a year.

Discussion
Diabetes mellitus is the metabolic syndrome characterized by chronic increases in blood glucose levels. China has more than 100 million cases of diabetes mellitus, making the incidence of the disease ranking first in the world [19]. 90% of diabetes is T2DM, and recent epidemiological reports have confirmed that the disease is closely related to malignancy due to the facts that malignancy occurs in T2DM patients at a significantly increased risk than the general population and that there is an important relationship between patient prognosis and glycemic control [20]. Bjornsdottir and other scholars pointed out that T2DM increased mortality in patients with prostate cancer, with implicated factors including insulin-like growth factor I, insulin, blood glucose, and HbA1c. Insulin-like growth factor I and insulin are able to promote tumor development, long-term maintenance of high blood glucose levels increases the risk of prostate cancer recurrence, and prostate cancer patients with T2DM undergoing radical prostatectomy have a 50% increase in recurrence rate compared with prostate cancer patients with normal blood glucose values [21], suggesting that blood glucose levels may serve as a predictor of postoperative recurrence in T2DM patients with prostate cancer. erefore, it is extremely important to strengthen the glycemic control of patients. However, the universal glycemic control rate across China is low, which is less than 10% even in Shanghai, where medical conditions and scientific research conditions are more advanced, and the  Figure 1: Comparison of patients' survival time and disease progression (‾x ± s, months). e horizontal axes from left to right denote the experimental group and the control group, and # denotes P < 0.001. In Figure 1(a), the vertical axis indicate the survival time, of which the experimental group was significantly higher than the control group (40.56 ± 8.96 vs. 28.12 ± 7.98, P < 0.001). In Figure 1(b), the vertical axis indicate the disease progression, of which the experimental group was significantly higher than the control group (34.21 ± 2.56 vs. 25.12 ± 2.98, P < 0.001). 2.89 ± 0.45, P < 0.001). In Figure 2( [22], showing that diabetes management is still an important problem in the management of chronic diseases in China. Based on the Guiding Opinions on Actively Promoting the "Internet Plus" Action Plan released by the State Council, Han and other scholars proposed the "Internet Plus" chronic management model, aiming to make the most of the convenience of the Internet, improve the use efficiency of medical resources, reduce the medical cost of chronic disease management, and enable diabetic patients to obtain better medical services [23]. e results of Han et al. showed that the "Internet Plus" chronic management mode could improve metabolic parameters in T2DM patients, with significantly higher selfcare scale scores in patients with diabetes than in those in the control group (P < 0.001), which was similar to the results herein, in which the experimental group had significantly higher posttreatment 2-DSCS scores than the control group (P < 0.001), demonstrating that this chronic disease management model could achieve seamless docking of home care and hospital resources, promote the information sharing between doctors and patients, and fully address the decreasing regulatory efforts when patients were at home. To improve the efficiency of "Internet Plus" chronic management mode, Wechat miniprogram, with the advantages of real-time operation and convenience and the utilization better than computer-based platforms, was used as a tool in this study. For patients with prostate cancer, mobile phones are also a more practical tool. In this study, after regular entry of personal information, the patient's T2DM data and prostate cancer data were under dynamic regulation, so the improved glycemic control rate and posttreatment blood glucose indicators of the experimental group were significantly better than those of the control group (P < 0.001).   Figure 3: Comparison of patients' immune function indicators (‾x ± s). e horizontal axes from left to right denote T 1 , T 2 , and T 3 , the lines with dots denote group A, and the lines with blocks denote group B; and # denote P < 0.001. In Figure 3(a), the vertical axis indicate the CD3 + cells; at T 1 , the CD3 + cells of the two groups were not statistically different (56.98 ± 2.10 vs. 56.23 ± 2.14, P > 0.05); and at T 2 and T 3 , the CD3 + cells were significantly higher in the experimental group than in the control group (58.11 ± 2.14 vs. 53.29 ± 2.10, 60.23 ± 2.15 vs. 49.54 ± 2.13, P < 0.001). In Figure 3(b), the vertical axis indicate the CD4 + cells; at T 1 , the CD4 + cells of the two groups were not statistically different (34.21 ± 2.10 vs. 34.41 ± 2.23, P > 0.05); and at T 2 and T 3 , the CD4 + cells were significantly higher in the experimental group than in the control group (37.68 ± 2.12 vs. 33.24 ± 2.11, 40.25 ± 2.41 vs. 30.98 ± 2.10, P < 0.001). In Figure 3(c), the vertical axis indicate the CD8 + cells; at T 1 , the CD8 + cells of the two groups were not statistically different (30.13 ± 1.89 vs. 30.20 ± 1.87, P > 0.05); and at T 2 and T 3 , the CD8 + cells were significantly lower in the experimental group than in the control group (28.98 ± 1.68 vs. 32.10 ± 2.14, 26.41 ± 1.41 vs. 32.89 ± 1.88, P < 0.001). In Figure 3(d), the vertical axis indicate the CD4 + /CD8 + ratio; at T 1 , the CD4 + /CD8 + ratios of the two groups were not statistically different (1.19 ± 0.32 vs. 1.18 ± 0.30, P > 0.05); and at T 2 and T 3 , the CD4 + /CD8 + ratios were significantly higher in the experimental group than in the control group (1.25 ± 0.15 vs. 1.13 ± 0.11, 1.32 ± 0.23 vs. 1.12 ± 0.20, P < 0.001).
Improvement in blood glucose indicators is key to the consolidation of therapeutic effects in prostate cancer. Hyperglycemia inhibits docetaxe-induced apoptosis of prostate cancer cells, while there is a positive correlation between HbA1c and metastasis of prostate cancer, so the numerical reduction of both is beneficial for Bushenyiliu decoction to exert therapeutic effects. In Bushenyiliu decoction, epimedium herb, malaytea scurfpea fruit, glossy privet fruit, phellodendri amurensis cortex, and other herbs can inhibit proliferation and induce apoptosis of PC-3 cells and are conducive to slowing down the progression of prostate cancer, which has been proved in the in vitro study [24]; in addition, mongolian milkvetch root and tangshen have the effect of supplementing spleen to nourish lung, while largehead atractylodes rhizome can invigorate stomach, and fried orange fruit plays a role in regulating functional activities of vital energy and helping the patients to regulate their qi and blood; from the perspective of modern pharmacology, although tangshen cannot accelerate the rate of tumor cells apoptosis, it can promote the cellular metabolism in malignant tumor host, and there is a counterpromotion effect of largehead atractylodes rhizome, which can selectively inhibit the cell subset of malignant tumor responsible for metastasis; mongolian milkvetch root is able to accelerate protein synthesis, promote energy metabolism, and induce the generation of interleukin, the anticancer factor in the body, tuckahoe can affect the macrophage and lymphocyte, and coixenolide in the coix seed can fully enhance body immunity. Hence, the immune function indicators of the experimental group were significantly better than those of the control group after treatment (P < 0.001).
In conclusion, with the combined action of multiple factors, the DCR and ORR of the experimental group were significantly higher than those of the control group (P < 0.05), and so were the survival time and disease progression (P < 0.001), indicating that the Internet-based chronic disease management mode combined with the modified therapy of Bushenyiliu decoction can effectively enhance the self-care ability of patients with T2DM and prostate cancer, improve their blood glucose level, boost their body immunity, and comprehensively optimize the cancer control effect, which should be promoted in practice.
