Objective:To study the impact factors of psychological distress in patients with first diag-nosed lung cancer.Methods:The cross-sectional study was applied to newly diagnosed lung cancer pa-tients who received treatments in Cancer Center of West China Hospital of Sichuan University in Chengdu from June 201 3 to March 201 5 by distributed questionnaires.The general information of the patients,the hospital anxiety and depression scale (HADS)and distress management screening measure (DMSM) were included in the questionnaire to evaluate the states of distress,pain and the factors related to the distress of the patients.Results:The survey investigated a total of 390 patients with first diagnosed lung cancer,including 291 male patients and 99 female patients.The proportion of the patients with positive anxiety symptom was 26.7% (1 04 /390),with positive depression symptom was 27.7% (1 08 /390), and with positive distress symptom was 30.0% (1 1 7 /390).On the top five problem list of DMSMwere worry,disease treatment,breathing,pain and sleep.The Spearman correlation analysis showed that an-xiety score,depression score,and the pain intensity were positively correlated with the distress.Multiple linear regression analysis showed that gender (β=-0.209,P =0.003),age (β=-0.098,P =0.042),chronic disease (β=0.378,P <0.001 ),and pain score (β=0.1 00,P =0.029)could affect the distress of the patients.Smoking (β=0.1 1 1 ,P =0.041 )could affect the anxiety of newly diagnosed lung cancer patients.Conclusion:The gender,age,chronic disease and pain score of the patients are the independent factors of the psychological distress of first diagnosed lung cancer patients.Smoking is the predictive factors of the patients with anxiety.Controlling the pain intensity and the clinical process of chronic disease of the patients actively,solving the sleep and breathing problem and helping the patients to quit smoking progressively could alleviate the psychological distress of the patients.

Objective To explore the effect of cognitive behavioral intervention on quality of life and distress of cancer patients. Methods The research was a random control study, and computer randomized grouping, the experimental group and control group contained 64 cases, 66 cases, respectively. The control group only accepted health education, while experimental group accepted cognitive behavioral intervention twice a week. Before and after the research, the patients were investigated with quality of life and distress scale. Results After the study of cognitive behavioral intervention, quality of life of experimental group scored (71.7±17.5) points which showed greater improvement than the control group scored (63.9±18.3) points (t=2.2,P<0.05), the distress score of experimental group was (2.6±0.6) points which was significant lower than the control group scored (3.9 ±0.7) points (t=11.8, P<0.05), and the proportions of distress problems contained anxiety [42.2% (27/64)], pain [29.7% (19/64)], depression [35.9% (23/64)] and sleep [23.4% (15/64)] in the experimental group were all significant lower than the control group [60.6% (40/66), 47.0% (31/66), 53.0% (35/66), 39.4% (26/66)]( X2=4.4, 4.1, 3.9, 4.5, P<0.05). Conclusions Short-term group cognitive behavioral intervention can alleviate the distress and pain, improve their negative emotions and sleep, eventually improve the quality of life of cancer patients.

Objective: To explore the effect of quality control circle(QCC)on reducing the incidence of moderate or severe malnutrition in gastric cancer patients under chemotherapy. Methods: Before the activity (February to March 2016), 146 gastric cancer patients under chemotherapy were selected as the control group, and regular nutrition nursing (dietary guidance and regular nutrition-related health lectures) was given. After the activity (February to March 2017), 139 gastric cancer patients under chemotherapy were selected as QCC group, and the standard intervention of quality control circle was implemented. The nutritional status of patients before and after improvement was compared. Results: After finding the cause and formulating and implementing the measures, the 24-hour consultation rate, the incomplete remission rate of nausea/vomiting, the incidence of cancer anorexia, and the rate of missed visits in QCC group were significantly different with those in control group (P<0.05). The incidence of moderate or severe malnutrition was 16.55% in QCC group and 65.07% in control group, and the difference was statistically significant (P<0.01). Conclusions The quality control circle activity can effectively reduce the incidence of moderate or severe malnutrition and improve the quality of life in gastric cancer patients under chemotherapy. It can also improve the self-discipline and initiative of medical staff and improve the quality of medical care.

OBJECTIVE:To develop a method for rapid determination of moisture and salidroside in Rhodiolae crenulatae.METHODS:The content of moisture was determined by the methods of oven drying (as reference value);the content of salidroside was determined by HPLC (as reference value).Near infrared spectroscopy (NIR) combined with partial least squares (PLS) algorithm were adopted to establish quantitative model for the contents of moisture and salidroside.According to reference value,83 samples were collected for preprocessing spectra by Savitsky Golay with second derivative and Norris Derivative with first derivative.The optimal spectrum range of moisture and salidroside were 7 343.60-6 865.34,5 183.72-4 890.59 cm-1 and 7 050.47-4 327.48 cm-1,respectively.RESULTS:The content determination methodology of salidroside was in line with the requirement.The correlation coefficients of calibration for moisture and salidroside were 0.968 9 and 0.920 3,and the root mean square errors of calibration were 0.273 0 and 0.085 0,respectively.The correlation coefficients of predication were 0.977 1 and 0.930 0,and the root mean square errors of prediction were 0.222 0 and 0.075 5,respectively.CONCLUSIONS:The method is proved to be simple,rapid,non-destructive and accurate,which can be used for the rapid determination of moisture and salidroside in R.crenulatae.
