Primary bronchial LC, referred to as lung cancer (LC), is one of the most common malignant tumors that seriously threaten people’s life safety. According to relevant clinical data statistics, LC has gradually become the largest cancer in China since 2004. Its morbidity and mortality are very high and increasing year by year, and it is also one of the tumors with the longest prognosis [1, 2]. LC has no obvious symptoms in the early stage, so its early diagnosis and treatment are lacking, and more than half of patients are already in stages IIIb and IV at the time of the first diagnosis. At present, the cure rate of modern medical treatment of the disease is low, the median survival is generally less than 6 months, and the 5-year survival rate is only 5–10% [3].
At present, relevant clinical studies have shown that cisplatin as the main body of two-drug combination therapy for patients with better conditions can reduce symptoms and prolong survival, relevant clinical trials and evidence-based medicine results show that the efficacy of systemic chemotherapy is better than supportive care alone. Combination chemotherapy can only increase one-year survival by 10% and is not significant for prolongation of survival [4]. IIIb standard treatment is the most common local treatment, and its general median survival is 11 ~ 13 months. However, it should be noted that patients with PS ≥ 2 had worse treatment outcomes and more intense toxicities compared with patients with PSO ~ 1. Currently, new drugs of clinical concern are gefitinib and erlotinib. Both drugs are EGFR-TKI and both belong to molecularly targeted drugs. Recent results of large-scale clinical studies in China and internationally have shown that oral administration of gefitinib and erlotinib in some non-responders to chemotherapy can control the incidence and control rate of the disease between 35% and 54%, with a median survival of 6 to 8 months [5]. In addition, targeted drugs and anti-vascular drugs, such as Endostar, have also shown good application prospects in the treatment of LC. However, the price of these drugs is generally high, which is the main reason that these drugs can’t be widely promoted in clinical practice [6].
At present, the treatment guidelines for LC still take the comprehensive treatment of western medicine as the main direction of treatment, but many adverse reactions (AR) expose the limitations of western medicine treatment. Many researchers in China try to treat LC using traditional Chinese medicine (TCM) [7, 8]. Some scholars have conducted a meta-analysis of clinical studies on LC treated with TCM alone in the past seven years. The results showed that the treatment of LC with TCM had the characteristics of high stability rate, and the TCM group showed obvious advantages in survival [9]. TCM treatment of cancer mainly includes acupuncture and drug treatment. Both methods take treatment with syndrome differentiation and eliminating pathogenic factors as the therapeutic principles, and achieve the effect of reconstructing the regulatory function of the body by regulating the function of qi, blood, yin and yang, and viscera of the body [10, 11]. However, most of the previous cancer research has been on drug therapy, and acupuncture has been lacking. In recent years, relevant clinical and experimental studies have shown that acupuncture plays a very important role in the rehabilitation of cancer patients by regulating qi and blood and promoting meridians. It can regulate the immune function of patients, play a role in relieving clinical symptoms, relieving pain syndrome, and reducing adverse reactions after chemotherapy [12, 13]. Existing clinical studies have shown that acupuncture combined with chemoradiotherapy can significantly reduce the immunosuppression caused by chemoradiotherapy, improve hematopoietic function, promote the increase of white blood cell count, improve the main symptoms and signs after chemotherapy, and significantly increase the total effective rate [14]. Therefore, acupuncture and moxibustion combined with comprehensive treatment can give full play to the advantages of various treatment methods, adjust the balance of the body's internal environment, and stimulate the body's various potential. In conclusion, acupuncture and moxibustion has a high application prospect in LC treatment, but there are not many related comprehensive application studies.
With the intellectualization of today's society, the application of artificial intelligence technology in clinical practice is more and more extensive, especially the emergence of medical robots provides more possibilities for clinical development [15]. At present, an intelligent acupuncture robot has been proposed by experts to assist clinical acupuncture treatment [16]. The intelligent acupuncture robot includes the function of automatic acupuncture, which will greatly reduce the working pressure of clinicians. In addition, in order to solve the problem that some patients are reluctant to perform acupuncture due to fear of pain, some experts have proposed a painless and infection-free laser acupuncture therapy [17]. The acupuncture treatment is designed and implemented on a smart phone by integrating a variety of machine learning algorithms and computer vision technology. The positioning error is less than 5 mm, convenient for patients to use, and has a good application effect.
Therefore, this work selected LC patients as research objects and combine automatic laser acupuncture therapy with comprehensive drugs to explore the effects of this therapy on patients' prognosis and side effects, so as to provide reference for the treatment of clinically related diseases.
