Objective To investigate the health-related quality of life (HRQOL), demographic characteristics, and health behaviors of the Chinese elderly to find out high-risk population and behaviors. Methods Data was collected from a cross-sectional survey performed in Jiangsu, Anhui, Gansu,Qinghai, Fujian, Beijing, Jilin, Jiangxi, and Henan province. MOS SF-36 was used for HRQOL assessment, t test was used for HRQOL comparison between the elderly and the general population. Multiple stepwise linear regression analysis was used to evaluate the affecting factors. Results The HRQOL among the Chinese elderly were PF ( Physical Functioning) 79 ± 21, RP ( Role-Physical ) 68 ± 40, BP ( Bodily Pain) 72 ± 23, GH ( General Health) 57±22, VT ( Vitality ) 69 ± 20, SF ( Social Functioning) 79 ± 23, RE ( Role-Emotional ) 72 ±40, M H ( Mental Health)76 ± 18, which were lower than Sichuan Norm on 7 dimensions ( P < 0. 05 ; except on M H dimension) and lower than Hangzhou Norm on 5 dimensions (P < 0. 05 ;except on GH, VT, and MHdimensions). The important affecting factors included physical exercise, education level, medical history of chronic disease, age, race, marriage, body mass index ( BMI ), sleeping habits, and gender. Conclusions Compared with the general population, the HRQOL in the elderly might be lower. The health policy and community heahhcare services should focus on the elderly individuals with insufficient exercise, lower education level, chronic disease history, and ethnic minority, or widows. Health education should encourage them to improve physical exercise and sleeping behavior.

Objective: To examine the relationship between traditional Chinese medicine (TCM) constitutional types and health status among groups of different age or gender in the general population of China. Methods: Data of 8 448 cases were randomly sampled from a database of 21 948 cases of a cross-sectional survey on the TCM constitutional types and health status which was carried out in 9 provinces or municipalities of China (Jiangsu, Anhui, Gansu, Qinghai, Fujian, Beijing, Jilin, Jiangxi and Henan) according to gender and age structure of the Chinese population in 2005. Scores of health-related quality of life scale--the Medical Outcomes Study 36-Item Short-Form Health Survey (MOS SF-36)--were analyzed by Nemenyi test to compare the health status of individuals with different constitutional types. Results: Compared with the gentleness type, the MOS SF-36 scores of the 8 types of pathological constitution were significantly low (P<0.05) among groups of different age or gender. The MOS SF-36 score was the lowest in men of the qi-deficiency, qi-depression and blood-stasis types, while it was the lowest in women of the phlegm-dampness, qi-depression and qi-deficiency types. For the age group of 15 to 34, the special diathesis, qi-depression and blood-stasis types had the lowest MOS SF-36 scores; for the age group of 35 to 59, the qi-deficiency, qi-depression and blood-stasis types had the lowest MOS SF-36 scores; for the age group of over 60, the qi-deficiency, qi-depression and phlegm-dampness types had the lowest MOS SF-36 scores. Conclusion: In groups of different gender or age, the MOS SF-36 scores of the 8 types of pathological constitution were significantly lower than that of the gentleness type, indicating a deficient health status. The health status of different types of constitution showed different characteristics in groups of different gender or age.

Objective:To investigate the efficacy and toxicity of oxaliplatin reintroduction combined with raltitrexed as second-line che-motherapy after the first-line oxaliplatin-based chemotherapy in advanced colorectal cancer patients. Methods:The 48 evaluable pa-tients with advanced colorectal cancer following disease progression prior to the first-line chemotherapy were treated with oxaliplatin and raltitrexed (raltitrexed 3 mg/m2 ivgtt d1, oxaliplatin 100-130 mg/m2 ivgtt d1, q21d). All 48 patients were divided into two groups:Group A, non-oxaliplatin-based regimens as the first-line chemotherapy, 20 cases;Group B, oxaliplatin-based regimens as the first-line chemotherapy, 28 cases. Each group was evaluated every two cycles. Results:The response rates (RR) of Groups A and B were 30.0%(6/20) and 32.1%(9/28), the disease control rates (DCR) were 80.0%(16/20) and 75.0%(21/28), the median progression free survival time (mPFS) was 6.5 and 7.0 months, and the median overall survival time (mOS) was 10 and 13 months, respectively. No statistical sig-nificance was observed between the two groups in their RR, CR, mPFS, and mOS (P=0.264, 0.514, 0.713, 0.788), respectively. The most common adverse effects observed wereⅠ-Ⅱgrades of bone marrow suppression, aminotransferase abnormality, and digestive toxici-ties. The incidence of neurotoxicity (Ⅰ-Ⅱgrades) between the two groups was similar. Conclusion:Instead of irinotecan combined with raltitrexed, oxaliplatin reintroduction combined with raltitrexed for second-line chemotherapy after the first-line oxaliplatin-based chemotherapy in advanced colorectal cancer patients is feasible.

Aim To study the mechanism of DSF-Cu induced apoptosis of human nasopharyngeal carcinoma CNE-2 Z cells by affecting the function of mitochondria and cytoskeleton. Methods The cell cycle,the rate of apotosis,the levels of intracellular ROS and MMP in CNE-2 Z cells were tested by flow cytometry after trea-ted with different concentration of DSF-Cu. The chan-ges of the cell surface morphology, ultrastructure, cell height, width and roughness were detected by AFM. The distribution and reorganization of cytoskeleton F-actin were observed by Laser scanning confocal micro-scope. Results Cells were incubated with different concentration of DSF-Cu ( 0 ~200 nmol · L-1 ) for 24 h, the apoptotic ratio increased significantly and the treatment of DSF-Cu resulted in a concentration-de-pendent accumulation of CNE-2Z cells in G2/M phase. Furthermore,the treatment of DSF-Cu was able to in-crease the production of intracellular ROS and decrease the MMP in CNE-2Z cells. In addition,AFM imaging showed that compared to the control group,with the in-crease of DSF-Cu concentration,the CNE-2Z cells be-came smaller, cytoplasm condensed, the height in-creased,and the surface roughness reduced. Moreover, the filopodia became shorter, shrinked and even com-pletely destroyed after treated with different concentra-tion of DSF-Cu. At last,the LSCM image showed that the fluorescence intensity of F-actin networks was de-creased, then the structure was rearranged and de-stroyed obviously by treated with DSF-Cu. Conclusion DSF-Cu can induce apoptosis and arrest cell cycle at G2/M phase in CNE-2Z cell through a mitochondria-dependent pathway. Above findings highlight the appli-cations of AFM at the single cell level for the investiga-tion of antineoplastic drug in nasopharyngeal carcinoma therapy.

OBJECTIVE:To provide reference for rational use of antibiotics in the clinic. METHODS:Blood culture positive specimens were collected from our hospital during Jan. 2011-Dec.2016. Distribution of bloodstream infection(BSI)pathogens and drug resistance were analyzed in our hospital retrospectively. RESULTS:During 2011-2016,26 034 blood culture specimens isolat-ed from inpatients of our hospital were examined,including 1 775 positive specimens with positive rate of 6.82%. The specimens mainly came from tumor hematology department(10.65%),neurosurgery department(8.28%)and pediatric department(8.00%). A total of 1 775 strains of pathogens were detected,including 967 strains of Gram-negative bacteria(54.48%)mainly as Escherich-ia coli,Klebsiella pneumoniae,649 strains of Gram-positive bacteria(36.56%)mainly as Coagulase negative Staphylococci, Staphylococcus aureus and 159 strains of fungus(8.96%)mainly as Candida albicans. E. coli and K. pneumoniae were resistant to common antibiotics to different extents,but sensitive to piperacillin sodium and tazobactam sodium,imipenem,meropenem. Aci-netobacter baumanii was highly resistant to enzyme inhibitors,cephalosporins,aminoglycosides,quinolones. Pseudomonas aerugi-nosa was sensitive to third-generation cephalosporins,aminoglycosides and quinolones. S. aureus was highly resistant to penicil-lins,cephalosporins and aminoglycosides. Resistance rate of Coagulase negative Staphylococci to most commonly used antibiotics was higher than 40%. Above two bacteria were sensitive to linezolid and vancomycin with resistance rate of 0. A total of 205 strains of ESBLs-producing E. coli(42.01%),64 strains of ESBLs-producing K. pneumoniae(30.33%)and 31 strains of Methicil-lin-resistant S.aureus(17.61%)were detected.No vancomycin-resistant Enterococcus or vancomycin-resistant S.aureus was detect-ed. CONCLUSIONS:BSI pathogens mainly distribute in tumor hematology department of our hospital. BSI pathogens mainly in-clude Enterobacteriaceae and Staphylococcus,and also involve fungus. The situation of drug resistance and enzyme production are not optimistic.Antibiotics,which are sensitive to the major pathogens,include carbapenems,linezolid and vancomycin.

Objective:To explore the effect of empathy nursing intervention on negative emotion, sleep quality and health literacy of patients with pulmonary tuberculosis.Methods:A total of 77 patients in Department of Infectious Diseases of People′s Hospital of Leshan from June 2019 to September 2020 were divided into intervention group ( n=39) and control group ( n=38) by random digits table method. The patients in the control group were given routine nursing, and the patients in the intervention group were given empathy nursing intervention on the basis of routine nursing. Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Pittsburgh Sleep Quality Index (PSQI) and Health Literacy Management Scale (HeLMS) were used before and 12 weeks after intervention to evaluate the effects. Results:There was no significant difference in the total scores of HAMD, HAMA, PSQI and HeLMS between the two groups before intervention ( P>0.05), but after intervention, the scores of HAMD and HAMA in the intervention group were 10.64 ± 1.86, 12.64 ± 2.12, lower than those in the control group (14.63 ± 2.19, 15.11 ± 2.71). The differences were statistically significant ( t=-8.63, -4.46, P<0.05). The total score of PSQI and the scores of daytime dysfunction, use of hypnotic drugs, time of falling asleep, time of sleep, sleep quality, sleep disorder and sleep efficiency in the intervention group were 10.26 ± 1.65, 1.22 ± 0.22, 1.48 ± 0.23, 1.51 ± 0.27, 1.45 ± 0.26, 1.57 ± 0.22, 1.54 ± 0.21,1.49 ± 0.24, lower than those in the control group (13.07 ± 2.14, 1.92 ± 0.31, 1.75 ± 0.34, 1.95 ± 0.29, 2.02 ± 0.33, 1.84 ± 0.31, 1.72 ± 0.27, 1.87 ± 0.29). The differences were statistically significant ( t values were -11.45--3.27, all P<0.05). The total score of HeLMS and the scores of information acquisition, communication and interaction, and health improvement intention in the intervention group were 96.12 ± 14.71, 37.87 ± 5.83, 35.91 ± 5.13, 16.21 ± 2.53, higher than those in the control group (86.35 ± 14.12, 33.17 ± 5.27, 32.87 ± 5.42, 14.16 ± 2.19). The differences were statistically significant ( t values were 2.53-3.80, all P<0.05). Conclusions:Empathy nursing intervention can effectively alleviate the negative emotions of pulmonary tuberculosis patients, improve their sleep quality, and improve their health literacy level.
