OBJECTIVE： To investigate pharmaceutical care of cancer pain therapy in medical institutions from Beijing area， and to provide reference for improving the quality of pharmaceutical care for cancer pain in medical institutions and formulating cancer pain therapy decision by public health administration departments at different levels. METHODS： Inspection results of standardized diagnosis and treatment for cancer pain were analyzed retrospectively in Beijing Pain Therapy Quality Control and Improvement Center during Feb.-Mar. 2018. Scoring results of pharmaceutical care （20 points） and its 5 sub-items （personnel participation， drug supply， drug management， outpatient prescription comment and inpatient prescription comment， 4 points each item） were analyzed statistically and classified according to hospital level and pharmaceutical care inspection results. RESULTS： A total of 64 hospitals in Beijing participated in the inspection， including 27 tertiary A hospitals （42.19％）， 21 tertiary B hospitals （32.81％）， 16 secondary hospitals or first-level hospitals （25.00％）. Pharmaceutical care in all hospitals met the inspection requirements with qualified rate of 100％. 52 hospitals performed excellently （81.25％）， and 12 hospitals were qualified for pharmaceutical care （18.75％）. Among 5 sub-items of personnel participation， drug supply， drug management， outpatient prescription comment and inpatient prescription comment， the average score of drug supply item was the highest （3.83±0.05）； the lowest was the personnel participation item （2.93±0.13）. The results of pharmaceutical care inspection in tertiary A hospitals （17.80±0.28） and tertiary B hospitals （17.78±0.30） were significantly better than those in secondary hospitals or first-level hospitals（16.16±0.50）（P＜0.01 or P＜0.05）； there was statistical significance only in the score of outpatient prescription comment among 5 sub-items（P＝0.026）. Total scores of the hospitals with excellent pharmaceutical care were significantly higher than those of the hospitals with qualified pharmaceutical care in terms of personnel participation， outpatient prescription comment and inpatient prescription comment （P＜0.01 or P＜0.05）. There was significant difference in the inspection results of pharmaceutical care among the excellent group， the qualified group and the unqualified group classified by the results of personnel participation item （P＜0.01 or P＜0.05）. CONCLUSIONS： The quality of pharmaceutical care for cancer pain therapy in medical institutions from Beijing area has reached the qualified level， but the participation of clinical pharmacists in cancer pain therapy and outpatient prescription comment still need improvement in further. The training of clinical pharmacists and information construction of narcotic drug management should be strengthened so as to improve the overall quality of pharmaceutical care for cancer pain.

This article reviews relevant literature on the prevention and treatment of cancer with hesperidin published in the past 10 years by searching electronic databases such as China National Knowledge Infrastructure（CNKI）， Wanfang， and PubMed， and summarizes the research progress on the anticancer mechanism of hesperidin. Hesperidin has a wide range of pharmacological effects， including anti-inflammatory， antioxidant， antibacterial， antiviral， anticancer， immune-regulatory， anti-radiation， neuroprotective and cardiovascular protective properties and so on. Its anticancer mechanisms mainly include inhibiting cancer cell proliferation， promoting apoptosis， reducing angiogenesis， inhibiting invasion and migration of cancer cells， regulating immunity and autophagy， and exerting antioxidant and anti-inflammatory effects. As a broad-spectrum anticancer drug， hesperidin manifests chemo-preventive and therapeutic effects across various cancers， contingent upon its multifaceted anticancer mechanisms. Furthermore， this article summarizes the synergistic effects of hesperidin in combination with cisplatin， doxorubicin， cyclophosphamide and paclitaxel. It elucidates that hesperidin can enhance the cytotoxicity of these anticancer drugs against cancer cells while mitigating drug resistance and adverse side effects. Nonetheless， the clinical use is somewhat constrained due to its poor water solubility and limited bioavailability. Therefore， this article also outlines the current strategies for enhancing hesperidin's bioavailability， including structural modification， combination with other chemical substances， and utilization of nano drug carriers.The discovery of derivatives of hesperidin not only preserves the anticancer efficacy of hesperidin, but also effectively overcomes the shortcomings of poor water solubility and low bioavailability of hesperidin, effectively predicting the good application prospects of hesperidin and its derivatives.
