Effect of Dingkundan in Adjuvant Treatment of Patients with Radiotherapy and Chemotherapy After Endometrial Carcinoma Operation / 中国实验方剂学杂志

Objective:To observe the effect of Dingkundan in adjuvant treatment of clinical symptoms， quality of life， immune function and prognosis of patients with radiotherapy and chemotherapy after endometrial carcinoma （EC） operation. Method:Patients were divided into control group （82 cases） and observation group （86 cases） according to random number table. A total of 75 patients in control group completed the study （4 patients fell off or lose visit， and 3 patients were eliminated）， while 77 patients in observation group completed the study （5 patients fell off or lose visit， and 4 patients were deleted）. After operation， patients got brachytherapy， external pelvic irradiation and chemotherapy. Patients in control group got Bazhenwan， 1 pill/time， 2 times/day， and those in observation group got Dingkundan， 7 g/time， 2 times/day. The course of treatment lasted for 4 months， and long-time follow-up data was recorded. Before treatment， and at the second and fourth month after treatment， deficiency of Qi and blood was scored. Toxic reactions after radiotherapy and chemotherapy were recorded， and incidence rate of acute and advanced radiation injury of bladder and rectum and toxicity of chemotherapeutic drugs at grade 3 or above grade 3 level were compared. And levels of T lymphocyte subsets （CD3⁺， CD4⁺， CD8⁺ and CD4⁺/CD8⁺） were detected， European collaborative quality of life Cancer Core Scale （EORTC QLQ-C30） was evaluated， and expressions of pce125 （CA125）， epididymis protein 4 （HE4）， Dickkopf-related protein-1 （DKK1）， vascular endothelial growth factor （VEGF）， matrix metalloproteinase-9 （MMP-9） and transforming growth factor-<italic>β</italic>₁ （TGF-<italic>β</italic>₁） were tested before and after treatment. The follow-up was made for every three months， and the progression （recurrence/metastasis） of patients was recorded. Result:Scores of deficiency of Qi and blood in observation group were lower than those in control group at the second and fourth week after treatment （<italic>P</italic><0.01）. Incidence rates of acute and advanced radiation injury of bladder and rectum and toxicity of chemotherapeutic drugs at grade 3 or above grade 3 level and incidence rates of bone marrow suppression， gastrointestinal toxicity， neurotoxicity were lower than those in control group （<italic>P</italic><0.05）. Five functional dimensions and overall quality of life score based on EORTC and QLQ-C30 in observation group were higher than those in control group （<italic>P</italic><0.01）， and scores of three symptom dimensions were lower than those in control group （<italic>P</italic><0.01）. Levels of CD3⁺， CD4⁺ and CD4⁺/CD8⁺ were higher than those in the control group （<italic>P</italic><0.01）， and CD8⁺ was lower than those in the control group （<italic>P</italic><0.01）. Levels of CA125， HE4， DKK1， VEGF， MMP-9 and TGF-<italic>β</italic>₁ were lower than those in the control group （<italic>P</italic><0.01）. The disease progression rate in observation group was 18.18% （14/77）， which was lower than 33.33% （25/75） in control group （<italic>χ</italic>²=4.572， <italic>P</italic><0.05）. Conclusion:In adjuvant treatment of patients with radiotherapy and chemotherapy after EC operation， Dingkundan can reduce the symptoms of Qi and blood deficiency syndrome and side effects caused by radiotherapy and chemotherapy， improve the quality of life and immune function， inhibit the expression of tumor markers and tumor growth factor， delay the progression of tumor and improve the prognosis.

RNA interference against interleukin-5 attenuates airway inflammation and hyperresponsiveness in an asthma model / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Interleukin-5 (IL-5) accompanies the development of airway inflammation and hyperresponsiveness through the activation of eosinophils. Therefore, interference of IL-5 expression in lung tissue seems to be an accepted approach in asthma therapy. In this study, we designed a small interfering RNA (siRNA) to inhibit the expression of IL-5. The siRNAs against IL-5 were constructed in a lentivirus expressing system, and 1.5x10(6) IFU (inclusion-forming unit) lentiviruses were administered intratracheally to ovalbumin (OVA)-sensitized murine asthmatic models. Our results show that lentivirus-delivered siRNA against IL-5 efficiently inhibited the IL-5 messenger ribonucleic acid (mRNA) expression and significantly attenuated the inflammation in lung tissue. Significant decrease of eosinophils and inflammatory cells were found in peripheral blood, bronchoalveolar lavage fluid (BALF), and lung tissue. In addition, significant inhibition of airway hyperresponsiveness (AHR) was found in the mice treated with siRNA against IL-5. These observations demonstrate that siRNA delivered by means of the lentivirus system is possibly an efficacious therapeutic approach for asthma.
