Research on the Strategies for Personal Information Protection in the Period of Normalization of Epidemic Prevention and Control / 中国医学伦理学

By analyzing the theoretical basis of safeguarding citizens’ personal information right during the normalization period of epidemic prevention and control, this paper concluded that there are some problems in personal information, such as solidified collection and utilization mode, low degree of management systematization, imperfect processing technology and narrow application scope, low degree of data value development and high risk coefficient. Further combined with China’s current epidemic prevention mode and social governance characteristics, this paper put forward the idea of innovating data hierarchical management and implementing the sharing mode in the industry to reduce the number of information circulation, trace the source, strengthen data desensitization technology and broaden its application scope, make rational use of personal information and appropriately develop its commercial use to increase its utilization efficiency.

Tolerance engineering regulates stress resistance of microbial cell factory / 生物工程学报

The production efficiency of microbial cell factory is determined by the growth performance, product synthetic capacity, and stress resistance of the strain. Strengthening the stress resistance is the key point to improve the production efficiency of microbial cell factory. Tolerance engineering is based on the response mechanism of microbial cell factory to resist stress. Specifically, it consolidates the cell wall-cell membrane barrier to enhance the defense against stress, accelerates the stress response to improve the damage repair, and creates tolerance evolutionary tools to screen industrial microorganisms with enhanced robustness. We summarize the regulation strategies and forecast the prospects of tolerance engineering, which plays an important role in the microbial cell factories for sustainable production of natural products and bulk chemicals.

Objective To investigate the illness uncertainty state of the family members of elder patients with colostomy,explore their correlation with social support.Methods A total of 138 family members of elder patients with colostomy in two hospitals from September 2013 to November 2014 were recruited in this study.The General Information Questionnaire,Mishel Uncertainty in Illness Scale-Family Member Form (MUIS-FM) and Social Support Rating Scale (SSRS) were used to investigate the family members of elder patients with colostomy and analyse the correlation between illness uncertainty of family members and its influencing factors and social support.Results The average total score of illness uncertainty was (72.17±9.44) scores.There was significantly different of the family members of elder patients with colostomy in total uncertainty on degree of education,the relationship with patient,stoma nature and economic conditions (P＜0.05).The average total score of social support was (37.14±5.25) scores.The level of illness uncertainty was negatively associated with social support (r=-0.526,P＜0.01).Conclusions The illness uncertainty was mostly in higher levels in the family members of elder patients with colostomy and was negatively correlated with social support.Clinical practice should improve social support of family members to relieve illness uncertainty,so as to provide better services of family and promote physical and psychological rehabilitation of patients.

Nutritional status of children during and post-global economic crisis in China / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To describe the impact of the global economic crisis on the nutritional status of children in China during and after the crisis.</p><p><b>METHODS</b>Data from 1990 to 2010 were sourced from the National Food and Nutrition Surveillance System. Approximately 16 000 children under 5 years old were selected using a stratified random cluster method from 40 surveillance sites. Anthropometric and hemoglobin measurements for children under 5 were conducted. Nutritional status was determined according to WHO child growth standards.</p><p><b>RESULTS</b>Prevalence of underweight and stunting in children under 5 had a downward trend. Underweight prevalence was close to normal (less than 5%), with prevalence of stunting 12.6% in 2009 and 12.1% in 2010 in rural areas. Prevalence of stunting in infants under 6 months and 6-12 months old in poorer rural areas increased from 5.7%-9.1% and 6.7%-12.5%, respectively, in 2008-2009. This trend also continued post-crisis in 2010. Prevalence of stunting in children left behind by mothers was 20%-30% higher than in children the same age in general and poorer rural areas. Prevalence of anemia in children did not change in rural areas, but prevalence of anemia in all age groups increased in poorer rural areas, especially in children under 24 months old. Level reached 30%-40% in 2009, and fluctuated in 2010.</p><p><b>CONCLUSION</b>The nutritional status of children under 5 was comparatively stable during and after the global economic crisis, attributable to the Chinese government's policy response. The nutritional status in poorer rural areas fluctuated in response to the economic crisis and, thus, relevant action and intervention must be taken immediately to help the most vulnerable population in poorer rural areas. A proper national nutritional strategy for children under 2 years old, including nutrition supplementation for pregnant women and in-home fortification for complementary feeding, should be initiated.</p>

Effect of the levels of serum gonadal hormone and plasma calcitonin gene-related peptide on the hot flushes symptom of perimenopausal women / 中国综合临床

Objective To study the effect of the levels of serum gonadal hormone and plasma calcitonin gene-related peptide(CGRP) on the hot flushes symptom of perimenopausal women. Methods 65 perimenopausal women (35 with hot flushes and 30 without hot flushes) and 25 healthy fertile women were enrolled. The subjects were analyzed for serum estradiol (E2), follicle-stimulating hormone (FSH) ,luteinizing hormone (LH) and plasma calcitonin gene-related peptide (CGRP). Results. ① There were no significant differences of the E2 levels between the perimenopausal women with and without hot flushes (P>0.05). The levels of FSH and LH were significantly higher in the women with hot flushes than women without hot flushes and fertile women(P<0.05),② The levels of plasma CGRP were significantly higher in the women with hot flushes than women without hot flushes (P<0.05), and significantly lower than fertile women,③The levels of plasma CGRP were significantly higher in severe hot flu-shes group than that in the mild hot flushes group and moderate hot flushes group(P<0.05), the severity of hot flu-shes was positively related to the level of plasma CGRP(rs=0.823, P<0.01), but there was no relationship be-tween serum E2 and the severity of hot flushes (P>0.05). Conclusion The occurrence of perimenopansal hot flu-shes might be closely related to the decline and fluctuation of serum E2,increase of FSH and LH and the concentra-tion variety of plasma CGRP.
