Effects of chronic disease management on patients with carotid atherosclerosis and the analysis of the related indicators / 中华健康管理学杂志

Objective To evaluate the effects of chronic disease management on carotid atherosclerosis. Methods From May 2016 to October 2016, 500 subjects with carotid atherosclerosis diagnosed by ultrasound at the Physical examination center of the First Hospital of Jilin University were enrolled. The participants were aged 55?65(60.7±3.5) years. They were divided into the control group (n=250) and intervention group (n=250) using a random number table; a total of 20patients, 13 in the control group and 7 in the intervention group, were lost to follow-up at the end of the study. The control group only received anti-atherosclerosis treatment, while the intervention group underwent additional chronic disease management, and a 1-year follow-up study was conducted. The health of all the subjects was assessed at the beginning of the study and after the study, based on the health file. The chi-square test, two independent sample t-tests, and rank sum test were used to evaluate the effect of chronic disease management on carotid atherosclerosis. Results After 1 year of intervention, the proportion of patients with an unhealthy lifestyle (smoking, excessive drinking, high-salt diet intake, high-fat diet intake, lack of exercise, and overweight/obesity) decreased in the intervention group(10.3%, 13.1%, 7.8%, 8.6%, 6.2%, 28.0%, vs. 28.8%, 35.0%, 21.0%, 22.6%, 13.2%, 39.5%; χ2=26.49, 33.01, 17.09, 18.03, 6.80, 7.21; P<0.05), while the drug compliance increased(44.4% vs. 35.4%, χ2=4.15, P<0.05), and the total cholesterol (TC), triglyceride (TG), low density lipoproteincholesterol (LDL-C), fasting plasma glucose (FPG), uric acid (UA) and blood pressure (BP) compliance rate also increased (91.8%, 73.3%, 83.1%, 83.1%, 52.3%, 76.5%, 74.1%, 60.5%, vs. 67.5%,72.8%,28.0%,58.8%, respectively; χ2=26.86, 8.92, 15.97, 7.49, 29.81, 17.39, respectively; P<0.05); all indicators, except the drug compliance control rate, were better than those in the control group. After 1 year of intervention, the degree of carotid atherosclerosis in the intervention group was significantly reduced compared to that in the control group. Conclusions Chronic disease management could effectively interfere the control risk factors of atherosclerosis, such as smoking, drinking, obesity or overweight, BP, levels of FPG, blood lipids, and UA, improve drug compliance, delay the progression of atherosclerosis and provide a basis for the construction of the atherosclerosis management model.

Risk factors for female pelvic organ prolapse and urinary incontinence / 中南大学学报(医学版)

To explore the risk factors for and the pathogenic mechanisms of pelvic organ prolapse and urinary incontinence.
 Methods: A total of 2 668 females who completed pelvic floor functional detection from July 2014 to October 2015 in the Physical Examination Center of the Third Xiangya Hospital of Central South University. The patients were divide into 4 groups: an urinary incontinence group, an organ prolapse group, an organ prolapse with urinary incontinence group, and a normal group. We compared the age, BMI, menopause, gravidity and parity, delivery pattern, the coordination of pelvic floor and abdominal muscles among the 4 groups.
 Results: There were statistical differences in age and BMI values among the 4 groups (P0.05). In the mode of delivery, there were statistical difference among the normal group and the other 3 groups (P0.05). Among the 4 groups, the normal group was the best one in coordination between pelvic floor and abdominal muscles, following by the organ prolapse group, the pelvic organ prolapse group and the urinary incontinence group.
 Conclusion: Aging, menopause, number of pregnancies and delivery, BMI, and mode of delivery all affect the occurrence of pelvic organ prolapse and urinary incontinence. Females with urinary incontinence or organ prolapse are not good in coordination between the pelvic floor and abdominal muscles.

Curcumin protects against the intestinal ischemia-reperfusion injury: involvement of the tight junction protein ZO-1 and TNF-alpha related mechanism

Present study aimed to investigate the eff ect of curcumin-pretreatment on intestinal I/R injury and on intestinal mucosa barrier. Thirty Wistar rats were randomly divided into: sham, I/R, and curcumin groups (n=10). Animals in curcumin group were pretreated with curcumin by gastric gavage (200 mg/kg) for 2 days before I/R. Small intestine tissues were prepared for Haematoxylin & Eosin (H&E) staining. Serum diamine oxidase (DAO) and tumor necrosis factor (TNF)-alpha levels were measured. Expression of intestinal TNF-alpha and tight junction protein (ZO-1) proteins was detected by Western blot and/or immunohistochemistry. Serum DAO level and serum and intestinal TNF-alpha leves were signifi cantly increased after I/R, and the values were markedly reduced by curcumin pretreatment although still higher than that of sham group (p<0.05 or p<0.001). H&E staining showed the significant injury to intestinal mucosa following I/R, and curcumin pretreatment signifi cantly improved the histological structure of intestinal mucosa. I/R insult also induced significantly down-regulated expression of ZO-1, and the eff ect was dramatically attenuated by curcumin-pretreatment. Curcumin may protect the intestine from I/R injury through restoration of the epithelial structure, promotion of the recovery of intestinal permeability, as well as enhancement of ZO-1 protein expression, and this eff ect may be partly attributed to the TNF-alpha related pathway.

Role of helicity of α-helical antimicrobial peptides to improve specificity

A major barrier to the use of antimicrobial peptides as antibiotics is the toxicity or ability to lyse eukaryotic cells. In this study, a 26-residue amphipathic α-helical antimicrobial peptide A12L/A20L (Ac-KWKSFLKTFKSLKKTVLHTLLKAISS-amide) was used as the framework to design a series of D- and L-diastereomeric peptides and study the relationships of helicity and biological activities of α-helical antimicrobial peptides. Peptide helicity was measured by circular dichroism spectroscopy and demonstrated to correlate with the hydrophobicity of peptides and the numbers of D-amino acid substitutions. Therapeutic index was used to evaluate the selectivity of peptides against prokaryotic cells. By introducing D-amino acids to replace the original L-amino acids on the non-polar face or the polar face of the helix, the hemolytic activity of peptide analogs have been significantly reduced. Compared to the parent peptide, the therapeutic indices were improved of 44-fold and 22-fold against Gram-negative and Gram-positive bacteria, respectively. In addition, D- and L-diastereomeric peptides exhibited lower interaction with zwitterionic eukaryotic membrane and showed the significant membrane damaging effect to bacterial cells. Helicity was proved to play a crucial role on peptide specificity and biological activities. By simply replacing the hydrophobic or the hydrophilic amino acid residues on the non-polar or the polar face of these amphipathic derivatives of the parent peptide with D-amino acids, we demonstrated that this method could have excellent potential for the rational design of antimicrobial peptides with enhanced specificity.
