Anticipatory nausea and vomiting (ANV) is one of the common adverse effects in cancer patients undergoing chemotherapy.ANV is related to classical conditioning,psychosocial and demographic factors.Psychological intervention such as systematic desensitization,hypnosis and biofeedback therapy could be used to treat ANV,while some psychotropic medication including benzodiazepines and olanzapine is also helpful to prevent ANV.Now the recognition about ANV in clinical oncology is not adequate and large sample epidemiological survey of ANV is lacked.So far there are no special tools to predict and assess ANV,and the effects of pharmacological interventions also need solid evidence from large sample double-blind randomized controlled trials.

Objective To construct the continuing nursing management model for lung cancer chemotherapy complications based on m-health. Methods Literature research, qualitative interviews and expert group meeting were used to build the continuing nursing management model for lung cancer chemotherapy complications based on m-health.

Conclusions The continuing nursing management model for lung cancer chemotherapy complications based on m-health has strong scientific and practical characteristics, which is helpful for patients to timely monitor the occurrence of complications of chemotherapy, access the corresponding prevention and intervention measures.

Objective:To determine if a group psychotherapy programme offers significant benefits to psycho-logical wellbeing for early and mid-term colorectal cancer patients compared to control group.Methods:Totally 67 patients previously diagnosed with colorectal cancer who participated in this study,34 patients accepted an invitation to join the intervention group,received 10 consecutive,weekly sessions group psychotherapy,and 33 patients served as control subject with usual care only.All participants were assessed at baseline and post-therapy (week 10 follow-ing enrollment or equivalent ).Assessment comprised self-completed Cancer Quality-of-life Core Questionnaire (QLQ-C30),Self-Rating Depression Scale (SDS)and Self-Rating Anxiety Scale (SAS).Results:At baseline, 67participants completed questionnaires,and 60 questionnaires returned at post-therapy,from 30 intervention group participants and 30 control group participants.Baseline scores for SAS and SDS were higher in intervention than control group[(42.0 ±7.7)vs.(36.0 ±6.8),(44.4 ±11.5)vs. (38.7 ±9.0),Ps <0.05],while other itemswere not differ(Ps>0.05 ).Post-therapy,intervention group participants reported significantly scores for anxiety, depression and fatigue compared with controlled group.In the comparison of before-post difference between inter-vention and controlled group,the difference of SAS score,SDS score,role function score and fatigue score showed significant discrepancy,intervention group improve significantly (Ps <0.05 ).Conclusion:Group psychotherapy could improve anxiety and depression,for colorectal cancer patients,and may help to improve quality of life,possi-bly through improving role function and decreasing fatigue symptoms.

Aim To study the activation of Nrf2 in-duced by baicalein ( BAI ) , and its protection against carbon tetrachloride ( CCl4 ) , ethanol and acetamino-phen ( APAP )-induced hepatotoxicity. Methods A reporter gene assay was conducted in human normal liver L-02 cells to detect the activation of transcription factor Nrf2 induced by baicalein. APAP ( 10 mmol · L-1 ) , CCl4 (10 mmol·L-1 ) and Ethanol (100 mmol · L-1 ) were used to induce hepatotoxicity in L-02 cells. After the pre-incubation with Baicalein (0, 1, 10, 25, 50, 100 μmol·L-1 ) for 15 min, cells were administrated with or without those above hepatotoxins. 48 h later, cell viability was detected by 3-(4, 5-dim-ethylthiazol-2-yl ) 2 , 5-diphenyltetrazolium bromide (MTT) method. Results Baicalein (25, 50 μmol· L-1 ) induced the activation of Nrf2 ( P <0. 01 , P <0. 05) in the reporter gene assay. As compared with control, three hepatotoxins ( APAP, CCl4 , Ethanol ) all decreased cell viability ( P<0. 01 ) , and baicalein significantly reversed such decreases in a concentra-tion-dependent manner ( P<0. 01 ) . Conclusion Ba-icalein can induce the activation of transcription factor Nrf2 , which is probably one of the mechanisms con-tributing to the protection of baicalein against hepato-toxins (APAP, CCl4, Ethanol)-induced hepatotoxici-ty.

Objective To investigate potential problems and solutions within the data of national surveillance of Keshan disease(KSD), to improve the quality of surveillance data and the reliability of the results. Methods Four key variables (name, sex, age, and KSD diagnosis) in the national surveillance data of KSD in 2009 were cleaned by SPSS 15.0. Cleaning contents included duplicate records, missing values, outliers and logic errors. Name, sex, age, currently residing in townships and currently residing in villages and other variables were combined into different filters to find duplicate records by the command of Identify Duplicate Cases , then the duplicate records were returned to the data reporting agencies, and finally delete or merge. Data with missing values, outliers, or logical errors were found by commands of Frequencies, Descriptives and Select if, then the duplicate records were returned to the data reporting agencies. Data were revised based on not only the feedback , but also by using the relationship between variables, and by consulting KSD clinical experts. Results Four hundred and sixty-four cases of duplicate records were found and cleaned. The number of missing values was 2 047 (specifically, name 0, sex 3, age 32 and KSD diagnosis 2 012). The number of outliers was 1 988 (specifically, name 6, sex 3, age 10 and KSD diagnosis 1 969). The records of 5 kinds of logic errors of KSD diagnosis were 105 in all. Conclusion There are duplicate records, missing values, outliers and logic errors in the national surveillance data of KSD, cleaning work could improve the quality of surveillance data, ensure the authenticity and rliability of the monitoring data.

Rotavirus is the leading causal agent of severe acute gastroenteritis in children aged <5 years. A specific pharmacologic agent for the treatment of rotavirus-infected children is lacking. In China, only the Luo Tewei oral vaccine (Lanzhou Institute of Biological Products, Shanghai, China), which is produced from Lanzhou lamb rotavirus vaccine (LLR), is available. Studies have hypothesized that the genotype of LLR is G10P[12], To identify the genotype of LLR by reverse transcription-polymerase chain reaction, we showed that the VP7 and VP4 genotypes of LLR were G10 and P[15], respectively, based on sequencing, alignment and phylogenetic analyses. In conclusion, we identified the genotype of rotavirus strain LLR to be G10P[15].

Objective To describe the epidemiological features of severe cases and deaths of pandemic influenza A (H1N1) 2009 in Beijing and to explore the main risk factors associated with the disease severity. Methods Data of pandemic influenza A (H1N1) 2009 reported in Beijing were collected and analyzed. The relative risks between disease condition and possible risk factors were determined using the multi-factor Logistic regression analysis. Results The incidence of pandemic influenza A(H1N1) 2009 was 66. 1/100 000, and the highest incidence was 86. 8/100 000 which occurred among people aged 25-60 years old. The prevalence of critical patients (12. 5/100 000 and 3.9/100 000, respectively), mortality (0. 9/100 000 and 0. 7/100 000, respectively) and fatality (2.4 % and 3.3 %, respectively) in people aged 0-5 years old and above 60 years old were higher than other age groups. There were 110 (20. 0%) preschool children among 549 critical cases, which were the largest proportion of critical cases. Among 69 death cases, 17 (24. 6%) were retirees with the highest proportion of death cases. More than 70. 0% of the critical cases and deaths visited hospital within two days of onset. The chronic heart disease and chronic lung disease were the most frequent risk factors of severe and death cases. Multi-factor Logistic regression analysis showed that the variables including aged above 60 years old (OR = 3. 586, 95 % CI = 1. 586 - 8. 117), chronic heart disease (OR=2. 126, 95%CI= 1. 178-3. 835), and chronic lung disease (OR=1. 954, 95%CI=1. 126-3. 391) were significantly associated with the disease severity. Conclusion Factors of aged above 60 years older, chronic heart disease and chronic lung disease may aggravate the severity of influenza A (H1N1).
