With the development of information technology, the massive growth of pharmaceutical electronic data and the significant increase in the reports of drug adverse event reports have brought great challenges to pharmacovigilance research. Data mining techniques can automatically extract the risk signals of adverse drug reaction from real-world data. Therefore, efficient data mining of massive adverse event reporting is a necessary measure to realize the automatic detection of adverse drug reactions. By introducing the current major large-scale adverse drug event reporting databases and related data mining methods, this study reviews the application and limitations of adverse drug reaction data mining technology in pharmacovigilance, which provides reference for pharmacovigilance-related institutions and researchers.

Objective:To explore the effect of hyperbaric oxygen (HBO) therapy on the healing of the skin flap, the vascular endothelial growth factor (VEGF) and hypoxia inducing factor-1α (HIF-1α) after modified radical mastectomy.Methods:A total of 132 patients with breast cancer admitted in the Department of Breast Surgery of Heping Hospital Affiliated to Changzhi Medical College from January 2017 to June 2019 were selected as the research subjects and randomly divided into control group ( n=66) and observation group ( n=66). The control group was given the modified radical mastectomy, while the observation group was additionally given hyperbaric oxygen therapy. The postoperative healing condition of incision flap, including healing time, drainage volume, and pain score, was compared between two groups. And the serum VEGF and HIF-1α levels of patients in the two groups were compared before and after the treatment. Besides, postoperative complications were also observed. Results:The healing time of the skin flap in the observation group with HBO [(10.43±0.96) d] was significantly shorter than that in the control group [(13.81±1.15) d]. The drainage volume of the observation group was (274.01±13.10) ml, and the visual analogue scale (VAS) were (4.02±0.34) and (2.84±0.30) on the first and the third day after the operation respectively. The healing condition and VAS scores of the observation group were both better than those in the control group, and all the differences were statistically significant ( P<0.05). Serum VEGF and HIF-1α levels in the observation group were (809.67±40.22) pg/ml and (243.71±22.84) pg/ml respectively, which were significantly improved compared with those before the treatment and those of the control group, and all the differences were statistically significant ( P<0.05). The incidence of postoperative complications in the observation group (3.03%) was lower than that of the control group (10.61%). Conclusion:The hyperbaric oxygen therapy has a significant clinical effect on the patient after the modified radical mastectomy. It can accelerate skin flap healing, relieve patients’ pain, and promote prognosis by reducing HIF-1α level and increasing VEGF content.

Objective To analyze the diagnostic value of serum procalcitonin (PCT), C-reactive protein (CRP) and interleukin-6 (IL-6) in the detection of incision infection after breast cancer surgery. Methods A total of 152 breast cancer patients admitted to our hospital from June 2016 to April 2018 were enrolled. All patients were given surgery.According to whether the wound infection occurred after operation, the patients were divided into control group (not infected, n=114) and observation group (infected, n=38). The serum levels of PCT, CRP and IL-6 were measured in the two groups on the 2 nd postoperative day. Results The average operation time and hospital stay in the observation group were longer than those in the control group (P<0.05). The serum levels of PCT, CRP and IL-6 in the observation group were higher than those in the control group (P<0.05). The positive rate of the observation group was higher than that of the control group (P<0.05). Conclusion In patients with breast cancer surgery, serum PCT, CRP and IL-6 detection can provide a good reference for the prediction of postoperative incision infection.

Diabetes is in the category ofin TCM, which is mainly discussed in light ofdeficiency. The conception vessel is the sea ofmeridians, acting on regulating the accumulation and irrigation ofand blood of twelve meridians and collaterals. The physiological function of the conception vessel is closely related to the pathogenesis of, its running course is highly coincident with the location ofand the symptoms ofare relevant with the indications of the conception vessel. Hence, harmonizingand blood of the conception vessel may be an effective approach to the prevention and treatment of.
