Objective:To explore the effect of sodium cantharidate vitamin B6 injections in the adjuvant treatment of advanced cer-vical cancers. Methods:Totally 60 cases of advanced cervical cancer patients were randomly divided into the observation group and the control group, and the control group was given common DP chemotherapy and radiotherapy, while the observation group was given sodium cantharidate vitamin B6 injections additionally. After the 6-week treatment, the short-term curative effect, bone marrow inhibi-tion adverse reaction, immune function and life quality were compared between the two groups. Results:The short-term curative effect in the observation group was 66. 7%, which was significantly higher than that in the control group (40%)(P<0. 05). The degree of adverse reaction was significantly lower than that in the control group with statistical significance (P<0. 05). After the treatment, CD8 +, NK cells and CD8 + / CD4 + in the two groups were significantly improved, and those in the observation group were all better than those in the control group (P<0. 05). The improvement of life quality in the observation group was more notable than that in the control group with statistical significance (P <0.05). Conclusion: Sodium cantharidate vitamin B6 injections can significantly in-crease the short-term curative effect and immune function, decrease bone marrow inhibition and improve life quality of advanced cervi-cal cancer patients.

Circulating tumor cells (CTCs) in breast cancer patients can be detected by Cell Search system. Results from recent studies suggested that CTCs level might serve as a prognostic marker and be used in the early assessment of therapeutic response in patients with metastatic breast cancer. However the role of CTCs in early stage breast cancer is not well established. Large prospective trials are needed to further understand its biological characteristics and to confirm its role as a predictive and prognostic marker.

Objective To observe the clinical effect of psychological intervention combined with somatostatin in the operation of pancreas. Methods From January 2016 to August 2017, 68 cases of pancreatic surgery were treated in our hospital. The patients were randomly divided into the observation group (n=34) and the control group (n=34). All patients were treated with somatostatin after the operation of pancreas. The patients in the observation group were treated with positive psychological intervention, and the effect of the application was observed. Results After the intervention, the two groups of patients with SAS and SDS were improved, the improvement is more obvious in the observation group (P<0.05);the observation group anal exhaust time, patients with gastrointestinal peristalsis time, bed time, hospitalization time were significantly shorter than the control group (P<0.05). Conclusion The combination of psychological intervention and somatostatin can improve the psychological status and promote postoperative recovery of patients after pancreatic surgery.

OBJECTIVE:To analyze volatile oil from the roots and fruits of Kadsura longipedunculata. METHODS:GC-MS method was adopted. The determination was performed on HP-5MS quartz capillary column with nitrogen as carrier gas at the flow rate of 0.9 mL/min.
