Guidelines for TCM Intervention After Conventional Western Medicine Treatment for Stage Ⅰ-Ⅲ Colorectal Cancer / 中国实验方剂学杂志

Colorectal cancer is one of the common malignant tumors with high morbidity， and changes in lifestyle， dietary structure and environment in China in recent decades have been associated with an increase in the incidence of colorectal cancer. A large number of studies have shown that traditional Chinese medicine（TCM） can be used as a complementary and alternative treatment for colorectal cancer after conventional western medicine treatment. TCM physicians have accumulated a lot of clinical experience in the treatment of patients with stage Ⅰ-Ⅲ colorectal cancer， and have proved that TCM has unique efficacy， but there is still a lack of relevant clinical practice guidelines to standardize and guide the diagnosis and treatment of TCM. Based on this， according to the guideline development process of the World Health Organization Handbook for Guideline Development and the Clinical Evidence Grading Criteria on TCM Based on Evidence Body， under the framework of relevant laws， regulations and technical guidance documents， combined with the evidence of relevant domestic and foreign clinical research in recent years for evidence grading and opinion recommendation， and then the Guidelines for TCM Intervention After Conventional Western Medicine Treatment for Stage Ⅰ-Ⅲ Colorectal Cancer were developed by expert consensus. This guideline introduces the etiology， pathogenesis， syndrome differentiation and treatment of TCM intervention for colorectal cancer， which can provide guiding opinions for TCM clinicians and clinicians of integrated traditional Chinese and western medicine engaged in the prevention and treatment of colorectal cancer.

Comparison of efficacy and safety between simultaneous integrated boost intensity-modulated radiotherapy and standard-dose intensity-modulated radiotherapy in locally advanced esophageal squamous cell carcinoma: a retrospective study.

OBJECTIVE: This study aimed to evaluate the efficacy and safety of simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) versus standard-dose intensity-modulated radiotherapy (SD-IMRT) in the treatment of locally advanced esophageal squamous cell carcinoma. METHODS: From July 2003 to March 2014, 1748 patients in a single center who received definitive chemoradiotherapy were included in the analysis. A total of 109 patients who underwent SIB-IMRT and fulfilled all inclusion and exclusion criteria were identified as the study group. A total of 266 patients who underwent SD-IMRT (60 Gy/30 fractions, 2 Gy/fraction, 1 time/day, 5 times/week) during the same period were selected as the control group. Propensity score matching (PSM) was used to balance the baseline characteristics. Survival status, treatment failure mode, and the occurrence of adverse events were compared between the two groups. RESULTS: There were more women and more cervical and upper thoracic cancers (P = 0.038, < 0.001, respectively) in the SIB-IMRT group before case matching. The median progression-free survival (PFS) in the SD-IMRT and SIB-IMRT groups was 22 and 19 months, respectively, and the median overall survival duration was 24 and 22 months, respectively, with χ2 = 0.244 and P = 0.621. After PSM of 1:1, 138 patients entered the final analysis (69 cases from each group). The median PFS of the SD-IMRT group and the SIB-IMRT group was 13 and 18 months, respectively, with χ2 = 8.776 and P = 0.003. The 1­, 3­, and 5­year overall survival rates were 66.7, 21.7, and 8.7% and 65.2, 36.2, and 27.3%, respectively, and the median overall survival duration was 16 and 22 months, respectively, with χ2 = 5.362 and P = 0.021. Treatment failure mode: 5­year local regional recurrence rates of SD-IMRT and SIB-IMRT were 50.7 and 36.2%, respectively, with χ2 = 2.949 and P = 0.086. The 5­year distant metastasis rates of the two groups were 36.2 and 24.6%, respectively, with χ2 = 2.190 and P = 0.139. ADVERSE EVENTS: 3 patients experienced grade 4-5 toxicity (2.2%), including one case of grade 4 radiation esophagitis and two cases of grade 5 radiation pneumonitis, all in the SD-IMRT group; 14 patients experienced grade 3 adverse events (10.1%), primarily including radiation esophagitis, radiation pneumonitis, and hematological toxicity. CONCLUSION: The technique of SIB-IMRT was safe and reliable compared with SD-IMRT. In addition, SIB-IMRT had locoregional control advantages and potential survival benefits.

Magnetic nanoparticle application in the biological sciences and medicine get rapid development over the past decades.In the current cancer therapy,hyperthermia has become a new treatment method after surgical therapy,radiotherapy,chemotherapy and biological therapy.With the advent of magnetic nanoparticles,magnetic targeting hyperthermia has provided a new method for tumor hyperthermia,and has a broad development prospects.

A Study on Enema Technology Optimization in the Treatment of Radiation Proctitis / 中国中医药信息杂志

Objective To explore the optimal method of treatment for radiation proctitis by keeping coloclysis with traditional Chinese medicine (TCM), including administation temperature, infusion time, dosage and catheter depth. Methods The orthogonal experimental design was adopted. Sixty-three patients with radiation proctitis were randomly divided into 9 groups, and they were under enema for 6 weeks according to different test conditions. TCM syndrome score, radiation injury effect and Karnofsky scores were set as evaluation indexes. An orthogonal design and analysis of variance were conducted for optimization. The best technical schemes for traditional Chinese herb in treating radiation proctitis were obtained. Results The obtained optimum methods are:drug temperature of (39±0.5)℃, infusion time of 30 minutes, dosage of 100 mL, catheter depth of 20 cm. Conclusion The optimal scheme of enema for the treatment of radiation proctitis is reasonable and feasible.

The incidence of postoperative complications of artificial abortion and its impact on physical and mental health of patients / 中国基层医药

Objective To investigate the incidence of postoperative complications of artificial abortion and its impact on physical and mental health of patients .Methods 123 patients underwent the artificial operation ( the observation group ) were followed up after operation , and 90 women without history of abortion were selected as the control group .The patients were asked by registration form and checked ,the incidence and the times of postoperative menstruation and complications were recorded .Results The incidence rate of gynecological disease in the observa-tion group was 26.8%,which was higher than 8.9% in the control group (χ2 =10.762,P0.05).The SAS score and SDS score of the observation group were (37.58 ±5.27)points and (44.26 ±5.81)points,respectively,which were significantly higher than those of the control group (t=9.87,10.43,all P<0.05).Conclusion After artificial abor-tion,the patients have multiple complications , and serious patients even affect pregnancy later , and have seriously impact on women's physical and mental health .

Effects of Changrui Enemas on expression of IL-1β and NF-κB in radiation-induced proctitis rats / 肿瘤研究与临床

Objective To observe the effects of Changrui Enemas on IL-1β and NF-κB in the rat model of radiation-induced proctitis, and to explore the mechanism of its repairing mucous membrane and diminishing inflammation. Methods Radiation was given on the pelvis of rats through linear accelerator to establish the model of proctitis. 70 rats were divided into seven groups randomly. Small dose (0.4 g/ml), middle dose(0.8 g/ml) and large dose(1.6 g/ml) of Changrui Enemas by retention enema were given for 7 days, with the admixture liquids of Gentamyein and Dexamethasone, Xilei Powder was used as controls. Changes of IL-1β and NF-κB expression were investigated by semi-quantitative RT-PCR and IHC respectively. Results The expression of IL-1β and NF-κB were determined in the groups accepted radiation, but there had been a dramatic decline in the treatment groups(P<0.05). The high dose treatment group was superior to the low dose one on the whole. Conclusion Changrui Enemas can down-regulate the expression of inflammatory factor IL-1β and NF-κB on radiation induced proctitis rats, and reduce the inflammatory reaction, protect the rectal mucosa, accelerate healing up of the ulcer and relief the symptoms.
