ABSTRACT
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.
ABSTRACT
In recent years， the incidence of colorectal cancer has been rising in China， and with the promotion of early screening and early diagnosis， most colorectal cancers are able to achieve long-term survival through timely diagnosis and treatment. Nevertheless， 30%-70% of patients with early to mid-stage colorectal cancer after radical surgery still have psychological problems such as anxiety， depression， and fear of recurrence and metastasis， and they hope to seek help from traditional Chinese medicine（TCM） treatment. In order to further standardize the integrated traditional Chinese and western medicine psychological rehabilitation interventions of stage Ⅰ-Ⅲ colorectal cancer after radical surgery， and to improve the diagnosis and treatment level， under the support of the pilot project of clinical collaboration between Chinese and western medicine for major and difficult diseases of National Administration of TCM， experts in oncology， integrated Chinese and western medicine， psychology， surgery， nursing， evidence-based medicine and other disciplines from 10 units nationwide participated in the work， led by Xiyuan Hospital，China Academy of Chinese Medical Sciences and Beijing Cancer Hospital. Based on the methodology and process of guideline development of the World Health Organization Handbook for Guideline Development and the Regulations for Group Standards of China Association of Chinese Medicine， the Guidelines for Psychological Rehabilitation Intervention Combined Integrated Traditional Chinese and Western Medicine After Radical Surgery for Early and Middle Stage Colorectal Cancer have been developed according to the current best evidence， extensive consultation with clinical experts and following the situation of current clinical practice. The guideline provides the psychological characteristics， the needs and willingness to accept psychological rehabilitation， the interventions for psychological rehabilitation， evaluation of efficacy， follow-up review， educational guidance and others of patients with stage Ⅰ-Ⅲ colorectal cancer after radical surgery. It can provide guidance for TCM（integrated Chinese and western medicine） clinicians and psychologists engaged in the psychological rehabilitation of integrated Chinese and western medicine oncology， especially for doctors in primary medical institutions.

ABSTRACT
This study was aimed to verify the effect of traditional Chinese medicine (TCM) dietary therapy in improving symptoms induced by chemotherapy.A total of 20 patients were included in the study according to the inclusion and exclusion criteria.The randomized autocontrol double-blind method was used in the trial.In group A,the dietary therapy was used in the first chemotherapy cycle,and the control therapy was used in the second chemotherapy cycle;and vice versa for group B.There were 3 cases fell out of the study.Finally,there were 8 cases in group A and 9 cases in group B.There were all together 17 patients.Observations were given on patients from both groups for 2 cycles.So the total observed case number was 34 person-time.Observations were given on differences of quality of life (QOL) and unpleasant symptoms (including fatigue,poor appetite,dry stool,loose stool,nausea and vomiting,night sweating,spontaneous sweating,dry mouth and throat,bitter taste in the mouth,pain,restlessness and irritable,insomnia and other symptoms) by TCM dietary therapy and control therapy on cancer patients during chemotherapy.The results showed that there was significant difference on the tenth day of chemotherapy from the QOL (P＜0.05).There was significant difference on the tenth day of chemotherapy from the total score of unpleasant symptoms (P＜0.05).Among them,there were significant differences on fatigue and poor appetite on the tenth day of chemotherapy (P＜0.05).It was concluded that TCM dietary therapy has certain effects in the improvement of patients' clinical symptoms during chemotherapy.On the tenth day of chemotherapy,the unpleasant symptoms of TCM dietary therapy group were lower than that of the control group (P＜0.05);the QOL score was higher in the treatment group than that of the control group (P＜0.05).After in-depth discussion,there was statistical significance on dietary therapy in improving fatigue and poor appetite in the dietary therapy group.It demonstrated that TCM dietary therapy help patients during chemotherapy.
ABSTRACT
Cox regression model is one of the most widely used methods in the survival analysis.One assumption of this model is that there is no tie in the failure times,that is,individual has different failure times.In practical applications,the existence of ties in time data is very common.In this paper,four common methods of dealing with ties in Cox model,including Exact method,discrete model method,Efron method and Breslow method,were compared with simulation.The results showed that Exact method and discrete model were the best,but they took the longest time.Efron method and Breslow method were faster but there was a greater deviation in parameter estimation.Moreover,the sample amount and ties degree also affect the results.In general,when there are a few ties,the difference between four methods was small;and in the case of large datasets or a large number of ties,the bias of three approximation methods increased except Exact method.However,there was no significant change on computational time.While the computational time of the Exact method increased rapidly.Therefore,if the estimation precision is not as important as the estimation time,Efron method and Breslow method will be good choices.Efron method is more preferably as it is more precise.And Breslow method tends to underestimate the true β.If there is no limit in time,Exact method and discrete model can be chosen to achieve more accurate results.
ABSTRACT
Elucidation of molecular mechanisms underlying host-pathogen interactions is important for control and treatment of infectious diseases worldwide. Within the last decade, mass spectrometry (MS)-based proteomics has become a powerful and effective approach to better understand complex and dynamic host-pathogen interactions at the protein level. Herein we will review the recent progress in proteomic analyses towards bacterial infection of their mammalian host with a particular focus on enteric pathogens. Large-scale studies of dynamic proteomic alterations during infection will be discussed from the perspective of both pathogenic bacteria and host cells.
