Objective:To evaluate the efficacy of computed tomography (CT)-guided implantation of radioactive ~(125)I seeds in the treatment of residual foci of nasopharyngeal carcinoma after radiotherapy.Methods:Twenty-five nasopharyngeal carcinoma patients who had residual foci after radiotherapy were implanted radioactive ~(125)I seeds from January 2007 to January 2008 in our hospital. Three-dimensional treatment planning system (TPS) was used to calculate the quantity and total dosage of ~(125)I seeds. The radioactive ~(125)I seeds were implanted into residual foci under CT guidance. The dosage distribution of radioactive ~(125)I seeds were verified after surgery. The nasopharyngeal endoscopy CT scans were performed at 3, 6, and 12 months after surgery and the short-term efficacy and adverse reaction were evaluated. Results:Out of the 25 patients, 20 patients had complete response (CR), 2 patients had partial response (PR), 2 patients had no change (NC), and 1 patient had progressive diseases (PD). The overall effective rate (CR+PR) was 88.0%. All patients had no serious postoperative complications. Conclusion:CT-guided implantation of radioactive ~(125)I seed was an effective and safe method in the treatment of the residual foci of nasopharyngeal carcinoma after radiotherapy.

0.05).Conclusion Multi-disciplinary techniques combined with 125Ⅰ seeds implantation is effective in the management of the malignant obstructive jaundice.No significant difference for relief and liver function were found between CT-guided and during operation interstitial 125Ⅰ seeds implantations,but it seems more quickly relief or recovery was achieved in the latter.

Objective To investigate the application value of extracorporeal extended field radiotherapy in locally advanced cervical cancer. Methods A total of one hundred and twenty patients with stage IIB?IVA cervical cancer in the First Affiliated Hospital of Hebei North University from June 2012 to June 2014 were randomly divided into two groups:the control group and the observation group,each with 60 cases. The routine concurrent chemoradiotherapy was adopted in the control group. The observation group was treated with extracorporeal extended field radiotherapy combined with concurrent chemotherapy. The patients have been followed up for three years. The total efficacy rate,toxicity reaction,local progression free survival time ( PFS) and survival rate of the two groups were compared. Results The total efficacy rate in the observation group was significantly higher than that of the control group ( 88. 3%( 53/60 ) vs. 73. 3%( 44/60 ) , χ2 = 4. 357, P=0. 037),while the incidences of toxicity reaction in the two groups were 18. 3%(11/60) and 16. 7%(10/60), the difference was not statistically significant (χ2=0. 058,P=0. 810) ,the percentages of I and II degree in the two groups were 3. 4%( 2/60 ) and 3. 4%( 2/60 ) , the difference between the two groups was not statistically significant (Z=0. 000,P=1. 000). The PFS value in the observation group was significantly longer than that of the control group ( 25. 6 months vs. 13. 8 months,χ2 = 25. 624, P= 0. 000 ) , and the survival rate in the observation group improved significantly ( 53. 3%( 32/60 ) vs. 33. 3%( 20/60 ) , the difference was statistically significant (χ2 = 4. 887, P= 0. 027 ) . Conclusion Extracorporeal extended field radiotherapy is safe and effective in the treatment of locally advanced cervical cancer.

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.
