γδ T cells possess both innate and adaptive immune characteristics. Their antigen recognition is independent of major histocompatibility complex presentation， and they can directly recognize abnormal tumor metabolism， showing unique application potential in tumors with low immune infiltration. This paper systematically sorts out the biological characteristics and antitumor immune functions of γδ T cells， and mainly reviews the relevant mechanisms by which active ingredients of traditional Chinese medicine regulate γδ T cells to exert antitumor immune functions. Glycyrrhiza polysaccharide and Astragalus polysaccharide can enhance the antitumor immune function of γδ T cells by promoting the expression of various cytokines， regulating intestinal flora and alleviating immunosuppressive state. Quercetin and puerarin can strengthen γδ T cell-mediated tumor cell killing by regulating the proliferation of γδ T cells， the expression of cytotoxic effector molecules and related signaling pathways. Toosendanin can potentiate γδ T cell-induced tumor cell killing by down-regulating the expression of anti-apoptotic protein in tumor cells. Artesunate can boost γδ T cell-mediated antitumor immune responses by enhancing the effector function of γδ T cells and weakening tumor immune escape. Future research shall focus on exploring the synergistic effects and molecular mechanisms of the combined application of active ingredients of traditional Chinese medicine and γδ T cell immunotherapy， and identifying the key targets for γδ T cells to exert antitumor immune functions.

Objective:To evaluate Zhuang medicine Fuzheng compound combined with epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) in the treatment of advanced epidermal growth factor receptor (EGFR) sensitive mutant non-small cell lung cancer (NSCLC).Methods:A total of 120 patients with advanced NSCLC who met the inclusion criteria from June 2019 to May 2020 in Guangxi International Zhuang Medical Hospital were divided into 2 groups according to the random number table method, with 60 in each group. The control group was treated with TKIs, and the observation group was treated with Zhuang medicine Fuzheng compound combined with EGFR-TKIs. TCM syndrome scores were compared, and the quality of life of the patients was assessed by the Quality of Life Scale (QLQ-C30). The serum levels of carcinoembryonic antigen (CEA), squamous cell carcinoma associated antigen (SCC-Ag) and carbohydrate antigen 50 (CA50) were detected by radioimmunoassay, and the levels of CD3 +, CD4 +, and CD8 + were detected by flow cytometry, and the CD4 +/CD8 + ratio was calculated. The adverse reactions during the treatment were observed and recorded. Results:The objective remission rate in the observation group was 66.7% (40/60) and the disease control rate was 81.7% (49/60), while in the control group were 48.3% (29/60) and 63.3% (38/60), respectively.The differences were statistically significant ( χ2 values were 4.13 and 5.06, P values were 0.042 and 0.025, respectively). After treatment, the scores of chest tightness, shortness of breath, blood in sputum, mental fatigue in the observation group were significantly lower than those in the control group ( t values were 8.72, 5.02, 5.47, all Ps<0.001), After treatment, QLQ-C30 score in the observation group was significantly higher than that of the control group ( t=5.21, P<0.01). After treatment, CEA [(31.45±4.56) mU/L vs. (38.98±5.71) mU/L, t=7.98], SCC-Ag [(4.87±0.93) μg/L vs. (7.29±1.25) μg/L, t=12.03], CA50 [(58.27±7.14) U/L vs. (66.48±7.94) U/L, t=5.96] levels were significantly lower than those in the control group ( P<0.01); CD3 +[(52.43±5.01)% vs. (48.56±4.87)%, t=4.29], CD4 + [(54.89±5.03)% vs. (51.09±5.22)%, t=4.06], CD4 +/CD8 + [(1.95±0.28) vs. (1.65±0.27), t=5.97] significantly higher than those in the control group ( P<0.01), CD8 + [(28.12±2.70)% vs. (31.23±2.64)%, t=6.38] significantly lower than that of the control group ( P<0.01). During the treatment period, the incidence of adverse reactions in the observation group was 13.3% (8/60) and that in the control group was 8.3% (5/60), with a statistically significant difference between two groups ( χ 2=0.78, P=0.378). Conclusion:The Zhuang medicine Fuzheng compound combined with EGFR-TKIs can reduce the level of tumor markers in patients with advanced EGFR-sensitive mutant NSCLC, improve patients' TCM syndromes, quality of life, enhance patient immunity, and improve efficacy.

Objective:To analyze the effect of morphine hydrochloride sustained-release tablets given by different administration routes on patients with cancer pain.Methods: Chosen patients with cancer pain as research subjects, underwent morphine hydrochloride sustained-release tablets for treatment of pain, randomized to receive oral administration as control group and rectally administration as observation group, observed pain relief degree, onset time of analgesia and adverse reaction rates.Results:1)After treatment, the observation group patients’ overall response rate was 94.05%,no significant difference compared with the control group; 2) After treatment, the observation group patients had a mean onset time (0.68 ±0.17) h, significantly shorter than the control group,0.5h, 1h, 2h, 4h of onset percentages of analgesia were higher than control group; 3)After treatment, the observation group patients’ incidence of adverse reactions was 2.38%, significantly lower than the control group.Conclusion: The morphine hydrochloride sustained release tablets rectal administration route can significantly alleviate cancer pain, shorten onset time of analgesia, and don’t increase the incidence of adverse reactions.
