Objective To investigate the resilience of primary caregivers of cancer patients undergoing chemotherapy and explore the influencing factors. Methods General information questionnaire and Cornor-Davidson resilience scale (CD-RISC) were used in the survey among 173 cancer patients undergoing chemotherapy as well as their primary caregivers. Results The score of resilience of primary caregivers was (70.76 ±13.34), at middle or above level. Multiple linear regression analysis showed that caregivers'resilience was affected by gender, age, family income and religious belief (all P<0.05). Conclusion The resilience among primary caregivers of cancer patients undergoing chemotherapy is at a relatively high level. Clinically, we should pay more attention to female and young patients with lower family income and no religious beliefs.

By using traditional Chinese medicine inheritance support system to analyze the dominant experience and recessive principles of the prescriptions for stranguria in the dictionary of traditional Chinese medicine prescription (DCMP), we aim to define the medication pattern and rule and to acquire new prescriptions. In dominant experience analysis, we were able to find 22 drugs used over 50 times, including drugs of clearing heat, diuresis and relieving stranguria which are the most used and drugs of clearing heat, cooling blood, benefiting Qi and nourishing Yin. In addition, drugs of activating Qi and Xue, eliminating phlegm and removing toxic are often used, including 34 herb pairs and 5 combinations of three-taste drugs are used more than 35 times. These results fully reflect the composition principles and compatibility characteristic of prescriptions for treating stranguria in DCMP. Thirteen new prescriptions by way of recessive principle excavating were acquired. These new prescriptions might be suitable to clinical treatments of variable syndromes. This article provides an useful clue to research and produce new drugs.

Objective To find out the differences of sleep posture between normal children and those with obstructive sleep apnea hypopnea syndrome(OSAHS),and assess the effects of sleep posture on the children with OSAHS.Methods The results of polysomnography(PSG) of 385 children diagnosed as OSAHS by polysomnography were compared with that of 161 children who matched the former in age and gender(Controls).The effects of different sleep posture on obstructive apnea,hypopnea index(AHI) and apnea index(AI) were analyzed.Results For the children with OSAHS when sleeping,the percentages of sleep time in different posture were 45.4%+36.3% in supine posture,39.5%+34.5% in side posture and 15.1%+32.6% in prone posture,respectively;while in control group,the correspond percentages were 32.8%+24.5%,54.7%+23.9% and 12.5%+17.2%,respectively.Comparing the two groups,significant differences existed on the sleep time in both supine and side posture(P0.05).Children with OSAHS spent more time in supine posture and less time in side posture than those children in control group(P0.05).For the children with OSAHS,the average AHI and obstructive AI in three sleep-related postures were 14.5 and 3.80,respectively.The values of both AHI and AI in supine posture were significantly greater than that in side or prone posture(P

More and more interest has been put on the investigations of saccharides recent years. Saccharides have a vast number of bioactivities and the immunomodulating effect of saccharides is one of the important mechanisms via which saccharides exert their bioactivities. Saccharides exert their bioactivities mainly by interacting with all kinds of saccharide receptors on cells, followed by a series of signal transduction process. In the present paper, numerous saccharide receptors and the characters of the mutual interaction between saccharides and their receptors are summarized.

Objective To investigate the passive smoking prevalence and its influencing factors among residents aged 15 and ol-der in Chongqing City ,and provide the evidence for the government to make tobacco control policy or improve the present tobacco control policy ,reduce the harm of secondhand smoke .Methods 753 non-smoker residents was investigated by using the multi-stage random sampling .Results The passive smoking rate of residents aged 15 and older in Chongqing city is 45 .95% ,among which ,the male′s is 43 .13% ,the female′s is 47 .45% ,there is no significant difference between gender distribution .There is a significant difference among different age groups(P<0 .05) ,the passive smoking rate of people aged 25 to 34 is the highest(55 .17% ) .There is a significant difference among different occupational groups (P<0 .05) ,the passive smoking rate of the people who engaged in commercial service is the highest(58 .01% ) .There is no significant difference among education level groups .About the non-smok-ers′attitudes to others smoking around ,the higher education level people have ,the more they will care about this ,the number of fe-male(87 .98% ) is significantly higher than male(70 .99% ) .Conclusion The harm of secondhand smoke to the residents aged 15 and older in Chongqing City is high ,so strengthening legislation and law enforcement is necessary to prevent the public exposure to secondhand smoke and reduce passive smoking level .

Objective To analyze the physical examination data of 557 faculty and staff working in one uni-versity,in order to provide a basis for control and prevent chronic disease in the same group people .Methods Five physical examination items including blood pressure ,blood sugar,cholesterin,triglyceride and blood uric acid were chosen and analyzed .Results The abnormal rate of high blood pressure was 20.83%,and that in males was obviously higher than the females(χ2 =26.82,P<0.05).The abnormal rate of high blood sugar was 9.69%,and that in males was obviously higher than females (χ2 =19.76,P<0.05).The abnormal rate of high blood uric acid was 16.52%, and that in males was apparently higher than the females (χ2 =10.89,P <0.05).The abnormal rate of high triglyceride was 28.55%,and that in males was obviously higher than females (χ2 =53.92,P<0.05).The abnormal rate of high cholesterin was 42.55%,there was no significant difference in gender (χ2 =0.00,P>0.05).Conclusion The health situation of faculties and staff is not optimistical .It is urgent to strengthen health education in these people .

Objective To explore the effects of three kinds of respiratory training methods on pulmonary function and quality of life in patients with thoracic cancer radiotherapy. Methods A total of 76 patients with thoracic cancer were divided into the control group (20 cases), the retracting-lip breathing group (19 cases), the blowing balloons group (18 cases), and the resisting respiratory exercise group (19 cases) by the draw method. Based on conventional health services, the retracting-lip breathing group, the blowing balloons group, and the resisting respiratory exercise group were given respiratory training (one month), whereas the control group only followed routine nursing care. The pulmonary function and quality of life were measured at the first and the thirtieth day of radiotherapy by electronic pulmometer and quality of life instruments for cancer patients-general module respectively. Results The indicators of pulmonary function at thirtieth day of patients in each group were lower than those at the first day, the intragroup differences were significantly (t=2.17-6.32, P<0.01), whereas no significantly different among intergroups (P>0.05). Scores of quality of life of the retracting-lip breathing group were (78.74±5.51) points, the blowing balloons group were (78.43 ± 7.41) points, the resisting respiratory exercise group were (79.11 ± 8.84) points, which were significantly increased than that of control group (73.01 ± 7.46) points(F=3.00, P < 0.05). Conclusions The pulmonary function of patients with thoracic cancer radiotherapy significantly reduces after radiotherapy. Three kinds of respiratory training show no effects on pulmonary function, but the quality of life of patients with thoracic cancer radiotherapy could be improved.
