Objective To investigate the protective effect of the combined application of carlbachol and compound dietary fiber on the intestinal barrier function in burn rats.Methods The 30％ total body surface area (TBSA) Ⅲ scald Wistar rats were randomly divided into four groups.Rats in group A were fed with physiological saline,in group B were fed with compound dietary fiber,in group C were fed with carlbachol and in group D were fed with carlbachol and compound dietary fiber.The rats were sacrificed at 6,12 and 24 hours after treatment,and selected normal rats for control group.Blood samples were taken for detecting plasma endotoxin,D-lactic acid,D-lactic acid content.Tissue samples were harvested from the small intestine for pathological study under light microscopy.Results (1) The damage of the structure of small intestine mucosa was different among 4 groups,and the most obvious was at 24 h after treatment.(2)The level plasma of endotoxin in Group D was (0.517±0.034) EU/L,significant lower than that in group A ((0.659±0.074) EU/L),Group B ((0.589 ±0.027) EU/L) and Group C((0.587±0.026) EU/L),and the difference was significant(P＜0.05).(3) Dlactic acid level in Group D was (102.996±10.102) μg/L,significant lower than that in group A((133.538 ±8.621) μg/L),Group B ((121.223± 10.519) μg/L) and Group C ((122.700± 11.146) μg/L),and the difference was significant(P＜0.05).Conclusion In early stage of burn shock,the therapy of combined with carlbachol and compound dietary fiber has obvious protective effect on rat intestinal barrier.Meanwhile,it is better than the treatment effect of single carlbachol or compound dietary fiber to some extent.

Objective To investigate the correlation between Toll-like receptor2 (TLR2) gene promoter region -597T/C polymorphism and primary ANCA associated small vasculitis (AAV) in Guangxi Han people. Methods A case contrastive control study was adopted in the study. Patients with AAV (patients group, n=110) and healthy people (control group, n = 200) were recruited. Associated serum indexes were detected and polymorphisms of TLR2 gene promoter 597T/C were analyzed by polymerase chain restricted fragment length polymorphisms (PCR-RFLP). Results (1)Three TLR2-597T/C genotypes were discovered in 110 AAV patients, namely, TT, TC and CC, with the frequency of 54.55%,40.00% and 5.45% respectively. And the frequencies of allele T and C were 74.55% and 25.45%. In control group, the genotype frequencies of TT, TC and CC were 56.00%,40.50% and 3.50%, with 76.25% of allele T and 23.75% of allele C. No significant differences were found in neither genotype distribution nor allele frequencies between the patients group and control group ( P > 0 . 05 ) . ( 2 ) Significant differences were found in the incidence of proteinuria rate and the hemoglobin (P< 0.05)in AAV patients. (3)There was no significant difference between AI and CI in TT, TC and CC genotype in AAV patients. Conclusions Polymorphism of TLR2-597T/C may be correlated with the incidence of proteinuria and the level of hemoglobin, while no obvious correlation with the genetic susceptibility of ANCA in vasculitis patients of Guangxi Han people.

Recently,as the exposure of the incident of‘octuplet’in Guangdong province,China's underground surrogate market has once again surfaced and led to a wide range of discussion.In this paper,the connotation and characteristics of surrogacy were analyzed and related laws and regulations of surrogacy in foreign countries were discussed.The main types of surrogacy-related legislation and regulations abroad are autonomy of private law,governmental regulation and complete prohibition.This paper carried out thorough legal analysis on whether to prohibit strictly or establish an authoritative legal system in view of the existing and ineffectively prohibited underground surrogate market in our country.

Objective To explore the induced effects of colchicine in different concentration and times on Foeniculum vulgare polyploidy.Methods Seed germination rate and mutation rate,morphology of radicle induced mutants,chromosome number,tissue structure,and content and component of essential oil,which induced by colchicine in different concentiation and times were investigaled using the method of soaking seeds.Results The results showed that 0.13% of colchicine concentration and 24 h inducing time had the best induction on F.vulgare polyploidy.Compared to the control,the radicle of mutant was thicker,the chromosome number increased clearly,and the cell number in radicle manifolded distinctly.Among the four main components of essential oil,the contents of Dill apiol in anamorphosis radicle was a little lower than that of the control,but the contents of limonene,(E)-anethole,and camphene in anamorphosis radicle were all remarkably higher than that of the control after induced by colchicine.ConclusionThe content of main essential oil components in fennel mutant induced by colchicine is remarkably enhanced.The study provides the theoretical basis for the breeding of F.vulgare new varieties of high oil content.

ObjectiveTo investigate the relationship between complement-3(C3) and progression of early cerebral infarction.Methods168 consecutive patients with acute cerebral infarction within the first 24 hours from onset were recruited.Fasting venous blood sample was drawn on the morning of the second or the third day after admission.C3 and other clinical chemistry variables were measured.The relationship of C3 and progressing stroke(PS) was analyzed by Logistic regression.Results68 cases(40.48%) were considered as PS.Level of serum C3 in PS patients was 1.28±0.20 g/L higher than in those with non-PS(1.16±0.25 g/L,P=(0.000)).A higher C3 accompanied a higher tendency of prevalence of PS(P=0.001).Logistic regression analysis showed that C3 was significantly correlated with PS(OR for each 1.0 g/L=7.27;95% CI=1.52～36.39; P=0.013).ConclusionElevated serum C3 may play an important role in the prevalence of PS.

Objective To investigate and explore the awareness and willingness of breast cancer screening between Han and Mongolian women in Ordos, Inner Mongolia Autonomous Region, and to analyze the influence factors. Methods The patients answered investigation questionnaires face to face, and the content of questionnaire included demographic information, breast cancer awareness and relevant affecting factors on the awareness and willingness. Results 11162 (88.2 %) Han women and 1495 (11.8 %) Mongolian women were enrolled in the survey, with the average age of (45.4 ±7.1) years old and (45.4 ±6.8) years old. The education level (high school and above) of Han women was lower than that of Mongolian women [4456 women (40.0%) vs. 750 women (50.2%), χ2= 57.041, P< 0.001]. The Main way to delivery information on breast cancer screening in Han and Mongolian women was from their family members or friends [5002 women (44.9%) vs. 688 women (46.1%),χ2=40.699, P<0.001]. The proportions of never attending screening in the Han and Mongolian women were 41.7 % (4640 women) and 45.9 % (683 women), respectively (χ2=14.075, P=0.001). The breast self-examination rate of Han women were higher than that of Mongolian [71.1 % (7926 women) vs. 58.5 % (872 women), χ2= 98.466, P< 0.001]. According to logistics regression analysis, the cognitive level of women with high education level and breast disease history was higher (all P<0.001). Conclusions The cognitive level of breast cancer screening in Han women is better than that in the Mongolian, however, the overall level are low. It is necessary to strengthen the propaganda and education, and to encourage women to actively participate in breast cancer screening.

Methods: A decorative coating manufacturing enterprise in Hebei Province was chosen as research object, following the types of occupational hazards and contact patterns, the occupational hazard risk index model was used to evaluate occupational health risk factors of occupational hazards in the key positions of the decorative coating manufacturing enterprise, and measured with workplace test results and occupational health examination. Results: The positions of oily painters, water-borne painters, filling workers and packers who contacted noise were moderate harm. And positions of color workers who contacted chromic acid salts, oily painters who contacted butyl acetate were mild harm. Other positions were harmless. The abnormal rate of contacting noise in physical examination results was 6.25%, and the abnormality was not checked by other risk factors. Conclusion The occupational hazard risk index model can be used in the occupational health risk assessment of decorative coating manufacturing enterprises, and noise was the key harzard among occupational harzards in this enterprise.

Objective:To determine the relationship between health self-empowerment level and health self-management skill in older adults.Methods:A household survey was conducted from June 2020 to April 2021, among older adults in two communities each in Zhuzhou and Changsha selected by stratified cluster sampling. Data were collected through a general questionnaire, simplified. Elders Health Empowerment Scale, and Rating Scale of Health Self-Management Skill for Adults. A total of 444 questionnaires were distributed, of which 425 were valid. Pearson correlation and hierarchical regression analyses were used to analyze the relationship between health self-empowerment level and health self-management skill.Results:Final sample included 425 elderly people. Health self-empowerment was at medium to high level (30.9±5.6), whereas health self-management was at medium level (146.2±21.7); and the two factors were significantly correlated (Pearson coefficient was 0.724). After controlling for confounding factors (demographic characteristics), health self-empowerment independently accounted for 34.3% of the variation in health self-management ability.Conclusion:Health self-empowerment positively affects health self-management ability among older adults, which suggests the importance of stimulating health self-empowerment awareness in the process of health self-management.
