Objective@#To explore the effects of community building environment and sports with fitness APP usage and their interactions on teachers exercise habits in the Yangtze River Delta Region, so as to provide a scientific basis for the development of a sports and health promotion intervention program for teachers.@*Methods@#A total of 2 530 in service teachers from four provinces and cities in the Yangtze River Delta region, namely, Shanghai, Zhejiang, Jiangsu and Anhui Province, were sampled in May-June 2023 by using convenient cluster random sampling method. Self designed questionnaire was used to collect the basic information of the surveyed teachers, Physical Activity Building Environment Evaluation Questionnaire and the Sports with Fitness APP Usage Questionnaire were used to measure the teachers subjective perception of the community building environment and the usage of sports with fitness APP, respectively. Physical Exercise Habituation Scale was used to assess the level of exercise habits. Logistic regression models were applied to analyze the effects of community building environment and sports with fitness APP usage on physical exercise, and the interaction effects were analyzed by using additive and multiplicative models.@*Results@#Among all the teachers surveyed, 658 of them reported good physical exercise habits (26.0%), and differences in the rate of physical activity habit formation by gender, age, years of teaching, as well as subject of teaching were statistically significant ( χ 2=42.94, 39.73, 35.47, 218.23 , P <0.05). Teachers with physical exercise habits had significantly higher community building environment scores and sports and fitness APP use than teachers without exercise habits ( t =12.17,16.54, P <0.05). Adjusting for the confounders of age, gender, years of teaching experience, and subjects taught, multifactorial unconditional Logistic regression analysis showed that the probability of teachers having good physical exercise habits increased by 22% for every 1-point increase in the community building environment score on average ( OR =1.22, 95% CI =1.11-1.40), and the probability of teachers having good physical exercise habits increased by 16% for every 1-point increase in the sports with fitness APP score on average ( OR = 1.16 , 95% CI =1.03-1.31) ( P <0.05). Interaction analyses showed that there was an additive interaction between the effects of community building environment and sports and fitness APP use on teachers physical exercise habits after adjustment, and the 95% CI for RERI , API and SI were 1.17 -1.65, 0.12-0.46 and 1.78-3.33 ( P <0.05), respectively, and there was no multiplicative interaction ( P >0.05).@*Conclusions@#The community building environment and the usage of sports & fitness APP show impacts in the formation of teachers physical exercise habits in the Yangtze River Delta region, and there is an interaction effect. Enhancing the construction of smart sports centers around the community can provide a high quality external environment for the physical exercise habits formation.

Expression of antimicrobial peptide Cecropin P1 in Saccharomyces cerevisiae and its antibacterial and antiviral activity in vitro

BACKGROUND: Cecropin P1, acting as an antimicrobial, has a broad-spectrum antibacterial activity with some antiviral and antifungal properties. It is a promising natural alternative to antibiotics which is originally isolated from the pig intestinal parasitic nematode Ascaris suum. Many studies have shown that Cecropin P1 is helpful for the prevention or treatment of clinical diseases. Therefore, it is very necessary to establish a safe, nontoxic, and efficient expression method of Cecropin P1. RESULTS: The results indicated that the recombinant protein was about 5.5 kDa showed by Tricine­SDS­ PAGE and Western blot. And Cecropin P1 was efficiently secreted and expressed after 12 h of induction, with an increasing yield over the course of the induction. Its maximum concentration was 7.83 mg/L after concentration and purification. In addition, in vitro experiments demonstrated that Cecropin P1 not only exerted a strong inhibitory effect on Escherichia coli, Salmonella sp., Shigella sp., and Pasteurella sp., but also displayed an antiviral activity against PRRSV NADC30-Like strain. CONCLUSIONS: Collectively, the strategy of expressing Cecropin P1 in Saccharomyces cerevisiae is harmless, efficient, and safe for cells. In addition, the expressed Cecropin P1 has antiviral and antibacterial properties concurrently.

Effect of diammonium glycyrrhizinate and phospholipids complex oninflammatory gene expression induced by palmitic acid / 浙江大学学报·医学版

To investigate the effect of glycyrrhizinate and phospholipids (DGPL) complex on inflammatory gene expression in cell inflammation model induced by palmitic acid (PA).Huh7 cells were divided into control, PA and PA+DGPL groups. For control group, cells were treated with BSA; for PA group, cells were incubated with 0.2 mmol/L saturated fatty acid PA, PA+DGPL group was given 20 μmol/L or 100 μmol/L DGPL in addition to 0.2 μmol/L PA. After 24 h, the expression of inflammation-related genes COX-2 and iNOS and endoplasmic reticulum (ER) stress-related gene GRP78 was determined by RT PCR. Oil red staining was conducted to observe the effect of DGLP on steatosis.Compared with control group, the expression of COX-2, iNOS and GRP78 in PA group was enhanced to 6.07±0.73(<0.05), 3.18±0.91 (<0.01) and 3.21±1.00(<0.05), respectively. Compared to control group, the expression of COX-2,iNOS and GRP78 in 100 μmol/L DGPL group was reduced to 2.40±0.76, 1.60±0.49 and 1.17 ±0.42 (<0.05); and 20 μmol DGPL had similar inhibition effect on COX-2 and iNOS elevation induced by PA (<0.01,<0.05 respectively). In addition, DGLP enhances the steatosis of Huh7 cells as demonstrated by oil red staining.PA can induce the up-regulated expression of inflammation associated genes COX-2, iNOS and ER stress-associated gene GRP78 in Huh7 cells. DGPL is able to protect Huh7 cells from PA induced inflammatory gene expression and the beneficial effect may be partially due to its unsaturated phospholipid component, which may improve ER stress and enhance steatosis.

Validation for access recirculation and access flow rate measurement by contrast-enhanced ultrasonography during hemodialysis / 生物医学工程学杂志

To evaluate the feasibility and accuracy of contrast-enhanced ultrasonography (CEUS) for the measurement of hemodialysis access recirculation (AR) and access flow rate (Qa), a two pump system was used to simulate access and dialyzer flow. AR and Qa under different conditions, such as reversal connection of dialysis lines and the needle orientation, were compared with each other. The value of access flow and recirculation flow were calculated based on the formulas introduced in this paper, and the correlation and consistency between true flow rate and calculated values were analyzed. The measured R correlated well with true value of flow rate (r = 0.57, P = 0.038, Qa > Qb; r = 0.95, P = 0.001, Qa < Qb). The Bland-altman test showed good agreement between the calculated value based on CEUS and true values. The CEUS can be used as a new advanced technology for AR and Qa measurement.

Objective To investigate the expression of Mta-1 in bladder transitional cell carcinoma (BTCC)and to analyze its correlation with the clinical staging,pathologic grading,metastasis and recur- rence,and to explore the possible molecular mechanisms.Methods Samples of 42 cases of BTCC and 12 normal bladder mueosa tissues were examined with immunohistochemical analysis for the expression of Mta- 1,ER,u-PA and PAI-1.Endothelial cells were stained by anti-CD34,and microvascular density(MVD)of carcinoma tissue was calculated.The correlation of Mta-1 expression with the invasion,metastasis,angiogene- sis and recurrence of BTCCs was analyzed;and the correlation of Mta-1 expression with ER,u-PA,PAI-1,and MVD was also analyzed.Results The positive rate of Mta-1 expression in BTCCs was 73.8%(31/42) , while it was 0.0% in normal bladder mucosa tissues(P＜0.01).The expression level of Mta-l increased with the higher clinical stages and pathologic grades of BTCCs;it was higher in recurrence group(100.0% , 15/15)than in non-recurrence group(59.3%,16/27),and high in metastasis group(100.0%,14/14) than in non-metastasis group(60.7%,17/28)(P＜0.05).The expression level of ER increased with the lower clinical stages and pathologic grades of BTCCs;the positive rate of ER expression was 0.0% in 14 ca- ses with metastasis and was 53.6% in 13 of 28 cases without metastasis(P＜0.05);and the rate was 6.7% in 1 of 15 cases with recurrence and 44.4% in 12 of 27 cases without recurrence(P＜0.05).Negative cor- relation was found between Mta-1 and ER expression(r=-0.739,P＜0.01).The positive rate of u-PA ex- pression(59.5%,25/42)was significantly higher in BTCCs than that in normal bladder mucosa tissues (16.7%,2/12)(P＜0.05).Positive correlation was found between u-PA and Mta-1 expression(r= 0.875),while negative correlation was found between u-PA and PAI-1 expression(r=-0.535).The posi- tive rate of PAI-1 expression in normal bladder mucosa tissues(50.0%,6/12)was significantly higher than that in BTCCs(19.0%,8/42)(P＜0.05).In addition,negative correlation was found between PAI-1 and Mta-1 expression(r=-0.706).And positive correlation was found between MVD in BTCCs marked by an- ti-CD34 and Mta-1 expression(r=0.683).Conclusions Mta-1 is highly expressed in BTCCs,and it correlates closely with tumor pathologic grades,clinical stages,recurrence and metastasis.Mta-1 up-regulates the expression of u-PA and down-regulates that of PAI-1,which is associated with invasion and metastasis and acts as an angiogenic mediator in BTCCs.A negative correlation is found between Mta-1 and ER in inva- sion and metastasis of BTCCs.
