OBJECTIVE To observe the clinical efficacy of Xuefu Zhuyu Decoction(XFZY)in the prevention and treatment of radiation-induced lung fibrosis(RILF)in esophageal cancer patients with blood stasis type underwent concurrent chemoradiotherapy(CRT).METHODS A total of 130 esophageal cancer patients with blood stasis type who treated with concurrent CRT were randomly divided into an experimental group and a control group,with 65 cases in each group.No patients dropped out during the study period.Patients in both groups received CRT and standardized symptomatic treatment was given according to the condition if radiation-induced lung injury occurred during treatment.On the basis of the treatment of the control group,the patients in the experimental group received XFZY from the beginning day until 30 days after the completion of CRT.The TCM syndrome score of the two groups were compared before and after treatment.The incidence of acute radiation pneumonia(RP)and chronic RILF and changes in pulmo-nary function indicators[forced expiratory volume in the first second as a percentage of predicted value(FEV1%pred),forced vital ca-pacity(FVC),FVC as a percentage of predicted value(FVC%pred),FEV1/FVC ratio,and carbon monoxide diffusing capacity as a per-centage of predicted value(DLCO%pred)]and serum cytokine levels[interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),hypoxia-inducible factor-1α(HIF-1α),vascular endothelial growth factor(VEGF),and transforming growth factor β1(TGF-β1)]were compared at 6 months and 12 months after the completion of CRT.The occurrence of adverse reaction during treatment was recorded.RESULTS The total score of TCM syndrome of the two groups was significantly improved and the experimental group was better than that of the control group(P<0.01)after treatment.The efficacy of TCM syndrome was better in the experimental group than that of the control group(P<0.01).There was no statistically significant difference in the incidence rate of acute RP between the two groups(P>0.05)at 6 months after the completion of CRT.The levels of lung function indicators FEV1%pred,FVC%pred,and DLCO%pred in the experimental group were higher than those in the control group(P<0.05),and the levels of various cytokines in the experimental group were lower than those in the control group(P<0.05).The incidence rate of chronic RILF in the experimental group was significantly lower than that of the control group(P<0.05)at 12 months after the completion of CRT.The DLCO%pred level in the experimental group was higher than that in the control group(P<0.01),and the levels of cytokines HIF-1α,VEGF,and TGF-β1 were lower than those in the control group(P<0.05,P<0.01).There was no serious adverse event observed in either group of patients during the treat-ment.CONCLUSION XFZY can effectively prevent and treat RILF in esophageal cancer patients with blood stasis type underwent CRT,reducing the loss to lung function caused by radiotherapy,and its mechanism may be related to downregulating the levels of cyto-kines of HIF-1α,VEGF,and TGF-β1.

OBJECTIVE To observe the clinical efficacy of Yangyin Jiedu Decoction in the prevention and treatment of acute ra-diation-induced oral mucositis(RTOM).METHODS A total of 80 inpatients who were diagnosed with head and neck tumors by pathological examination and received radiotherapy in the Department of Radiotherapy,Affiliated Hospital of Nanjing University of Chi-nese Medicine from November 2021 to September 2023 were selected and randomly divided into an observation group and a control group with 40 cases in each group.The control group was given mouthwash treatment from the onset of RTOM symptoms until the symp-toms disappeared;the observation group was given Yangyin Jiedu Decoction from the first day of radiotherapy on the basis of the treat-ment of the control group until the end of radiotherapy.During the treatment,the onset time,duration and incidence of grade Ⅱ-ⅣRTOM in the two groups were observed;the pain numerical rating scale(NRS)score,Karnofsky performance status(KPS)score,body mass index(BMI)changes were evaluated;and the levels of serum inflammatory factors[C-reactive protein(CRP),interleukin 6(IL-6),interleukin 1β(IL-1β),tumor necrosis factor α(TNF-α)]were detected.RESULTS After radiotherapy,RTOM ap-peared in both groups to varying degrees.The incidence of grade Ⅱ-Ⅳ RTOM,the onset time,duration and NRS score of RTOM in the observation group were significantly better than those in the control group(P<0.05,P<0.01).After radiotherapy,the levels of se-rum CRP,IL-6,IL-1β and TNF-α in the observation group were lower than those in the control group(P<0.05,P<0.01).After radiotherapy and 1 month of follow-up,the KPS score and BMI in the observation group were higher than those in the control group(P<0.05,P<0.01).CONCLUSION Yangyin Jiedu Decoction can decrease the incidence and severity of RTOM in patients with head and neck tumors,shorten its duration,improve the quality of life of patients,downregulate the level of inflammatory cytokines,and has a preventive effect on RTOM caused by radiotherapy in patients with head and neck tumors.

Background and purpose: The diagnosis of thyroid papillary carcinoma sometimes is difficult, metastasis of lymph node is the major reason of local relapse and influence prognosis.This study explores the immunohistochemical expression and their diagnostic value of CK19,HBME-1,galectin3,p27 and cyclinD1 in thyroid papillary carcinoma and the relations between p27,cyclinD1 and lymph node metastasis of papillary carcinoma.Methods: Immunohistochemical staining was used on 50 specimens of benign lesions (40 speciments of nodular goiters and 10 cases of follicular adenomas) and 50 specimens of papillary carcinomas (40 specimens of classic variants and 10 specimens of follicular variants) operated in our hospital from January of 2005 to December of 2008. Results: CK19,HBME-1 and galectin3 were expressed in cytoplasm or on the membrane, but p27 and cyclinD1 were expressed on the nucleus. The expressions of CK19,HBME-1 and galectin3 in thyroid papillary carcinoma were middle to strong positive, the positive ratios were 100%,96% and 100%, respectively;their expressions in benign lesions were negative or low positive, the positive ratios were 10%,10% and 6%, respectively;there were statistical differences between them (P<0.01). The expression of p27 in thyroid papillary carcinoma was low positive or negative, the positive ratio was 14%, but the expression of p27 in benign lesions was middle to strong positive, the ratio was 84%, there was also significant difference between them(P<0.01). The expression of CyclinD1 were similar in benign and malignant lesions of thyroid, the positive ratios were 68% and 78%, respectively, there was no statistical difference between them(P>0.05). There were significant differences(P<0.01) between the benign lesions and the papillary carcinomas in terms of the combination of CK19,HBME-1 and galectin3 expression and there were no significant differences(P>0.05) in the group of the former with underexpression of p27 between the two groups. The differences were not statistically significant (P>0.05) between the underexpression of p27 with the expression of cyclinD1 (the positive ratios in metastasis group and no metastasis group are 72.7% and 71.4%) in the lymph node metastasis. Conclusion: The combined immunohistochemical stainings of CK19,HBME-1 and galectin3 are useful on the diagnosis and differential diagnosis of thyroid papillary carcinoma, there is no predicted value of the underexpression of p27 with the expression of cyclinD1 for lymph node matastasis of thyroid papillary carcinoma.
