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 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 investigate influence of living locations on the personality characteristics of the only child and none-only children in an air force academy.Methods:1921 cadets were tested by the Chinese version of the MBTI-G.Results:Scores of the only child cadets from cities on the Sensing-Intuition and Thinking-Feeling dimensions were higher than those of none-only children group from cities and those of the only child group from countries.The scores of them on the SN scale were 93.0?18.5,90.4?17.6 and 90.1?17.7(t=2.25,P=0.025;t=1.99,P= 0.048).The scores of them on the TF scale were 94.6?22.6,89.1?21.1 and 88.4?21.0(t=4.02,P

Ever from FDA approved the Rituxan in 1997,an Anti-CD-20 chimeric antibody,there have been more than 20 antibodies approved and they have got into more than 56 countries.About half approvied antibodies are curing kinds of cancers and seven of them have got a excellent sale targets to be "Blockbuster Drug".As the cell culture technology improving,the large scale cell expression titer comes from 1g/L to 5g/L.At the same time,the culture scale is coming form 12,000L to 15,000L,even 20000L and it can run several bioreactors at the same time.All these are make the improvement of the antibody purification.The new edition of media,system,chromatography technology and filtration technology can product the protein to several tens kilogram antibody per cycle and tons per year,although the productivity is only several kilograms per cycle many years ago.Also the new combined technology makes a two-step chromatography production protocol come into been.This will highly improve the antibody productivity and save the investment cost.

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.

To investigate the repairing effect of fibrochondrocyte collagen construct in meniscus lesion, fibrochondrocytes were isolated and expanded in vitro , then seeded onto collagen construct .18 dogs with wedged shape lesion in the lateral meniscus were randomly divided into 3 groups: the lesion were filled with either cell collagen construct or collagen or untreated. The lateral meniscus was then examined grossly and histologically at different periods. The results showed that the lesions that had been filled with fibrochondrocyte collagen construct healed with fibrocartilage tissue. The results suggest that tissue engineering method is practical.
