Objective To investigate the serum levels of C-C motif chemokine ligand 25(CCL25)and human Parkinson's disease protein 7(PARK7)in patients with sepsis and their relationship with acute lung injury(ALI).Methods 138 sepsis patients diagnosed and treated in Hefei Jingdongfang Hospital from February 2019 to February 2023 were selected as sepsis group.They were divided into ALI group(n=40)and non-ALI group(n=98)based on whether ALI occurred.70 healthy individuals who underwent physical examinations at the same time were taken as a control group.Enzyme linked immunosorbent assay was used to detect serum levels of CCL25 and PARK7.The correlation between serum CCL25,PARK7 and clinical indicators were analyzed by Pearson correlation analysis.Risk factors for secondary ALI in sepsis were conducted by multivariate logistic regression analysis.The value of serum CCL25 and PARK7 levels in predicting secondary ALI in sepsis were conducted by the receiver operating characteristic curve.Results Serum CCL25(367.52±46.87ng/L)and PARK7(54.26±17.45μg/L)in patients with sepsis was higher than that of the control group(48.17±5.26ng/L,12.31±4.12 μg/L),and the differences were statistically significant(t=46.825,19.813,all P＜0.05).ALI group patients CCL25(434.65±52.87ng/L vs 340.12±42.64ng/L),PARK7(103.47±22.51μg/L vs 34.18±7.46 μg/L),respiratory index(1.58±0.48 vs 0.88±0.07),PaCO2(50.11±6.27mmHg vs 40.42±5.20mmHg),APACHE Ⅱ score(23.37±3.82 point vs 17.15±3.41 point)and SOFA score(13.56±2.93 point vs 10.18±2.81 point)were all higher in the non-ALI group,while oxygenation index(237.14±23.56 point vs 341.14±21.37 point)and PaO2(55.87±8.03mmHg vs 63.11±7.14mmHg)were lower in the non-ALI group,and the differences were statistically significant(t=10.998,27.151,14.145,9.342,9.385,6.332,25.172,5.210,all P＜0.05).The serum levels of CCL25 and PARK7 in ALI patients were positively correlated with APACHE II score,SOFA score,respiratory index and PaCO2(r=0.579～0.801,all P＜0.05),while negatively correlated with oxygenation index and PaO2(r=-0.687,-0.643;-0.654,-0.712,all P＜0.05).Serum CCL25(OR=1.309,95%CI:1.040～1.646),PARK7(OR=1.288,95%CI:1.016～1.633),APACHE II score(OR=1.188,95%CI:1.019～1.384)and SOFA score(OR=1.197,95%CI:1.006～1.425)were independent risk factors for secondary ALI in sepsis patients.The area under the curve(95%CI)of the combination of serum CCL25 and PARK7 for predicting secondary ALI in sepsis was 0.833(0.784～0.872),which was greater than the individual indicators 0.770(0.725～0.835)and 0.741(0.691～0.790),and the differences were statistically significant(Z=4.602,4.318,P＜0.05).Conclusion Elevated serum levels of CCL25 and PARK7 in patients with sepsis are independent risk factors affecting the occurrence of secondary ALI in sepsis.The combination of the two has high predictive value for secondary ALI in sepsis.

Objective To understand the cognition ,attitudes and needs of the science and technology achievement trans-formation policies among the medical personnel of 21 tertiary hospitals in Shanghai .Methods Convenient sampling method was used .The self-designed questionnaires were used to survey 420 personals in 21 tertiary hospitals in Shanghai ,and 411 valid questionnaires were responded with a valid rate of 97 .86％ .Results The cognition of science and technology achievement transformation policies of the respondents was low ,and the degree of cognition was related to the professional titles ( P<0 .05) .While the recognition degree of some policies was high ;40 .47％ agreed that enterprises could be the decision-maker during the transformation process ;85 .99％ agreed that it is OK to hire the Technology intermediary service agencies to evalu-ate the achievements value ,confirmed that need such agencies to provide the services of information collection and screening . Conclusions More Policy publicity should be enhanced among the medical personnel ,communications about their needs and suggestions on the science and technology achievement transformation should be carried out to further update related policies , as well as improve the transformation of science and technology achievements in health system .

Objective To investigate the causes of the dilemma in the medical patents transfer,analyze the corresponding countermeasures.Methods The research clarify the causes of the dilemma in the medical patents transfer and put forward countermeasures to promote the medical patents trans fer according to depth interviews to relevant personnel involved in medical patents transfer and literature analysis.Results A lot of factors,including the professionalism and technical of the medical patents,the special status of the inventor,the imperfect institutions,attitude of hospital administration to the medical patents transfer and environment which ignore the medical patents transfer,lead to the dilemma of the medical patents transfer.Countermeasures like the establishment of a special transfor mation entity,the incentives for transformation personnel,improve the transformation system and processes can promote the medical patents transfer.Conclusions Comprehensive consideration of the objective environment,the effective using of available resources,encouraging collaborations between hospitals and enterprises to making good use of their own advantages,as well as ask for related regulatory support,can help the smooth transfer of medical patents.
RÉSUMÉ
Objective To study the similarities and differences of information needs between cancer patients treated with radiotherapy and chemotherapy, analyze the causes for cancer patients' different choices, and provide reasonable and disease-related information for cancer patients. Methods A total of 102 and 119 cancer patients treated with radiotherapy and chemotherapy relatively were asked to complete the questionnaire (IPQCP+2) and two questions about the total information capacity and content requirements. Results Two groups had different needs of therapeutic information and treatment in IPQCP. Cancer patients treated with chemotherapy needed more widely-ranged information than patients underwent radio-therapy. Conclusions Most of cancer patients treated with radiotherapy and chemotherapy need to be informed of disease-related information, among which the content of therapeutic information and total information is relative to the treatment. Nurses should provide disease-related medical information based on their different needs, as to improve the life quality of cancer patients.
RÉSUMÉ
A series of research results on the influence of soybean to the bioavai?lability of non-heme iron in diet are reported. It is proved that Soybean and some of its products decrease the bioavailability of non-heme iron in diet by human observation and animal experiments. This result is due to insufficient control over the inhibitors and utilization of the enhancers of the bioavailability of iron in soybean itself.Experiments show that through some special treatment processes such as sprouting, fermenting and making bean curd, the above disadvantages may be effectively reduced and remarkably increase the bioavailability of the non-heme iron. These conclusions possess both theoretical and practical meaning for full utilization of soybean protein and effective prevention of iron deficiency anemia.
