Design and clinical application of peritoneal dialysis tube to prevent breakage / 中国实用护理杂志

Objective To design the protection of peritoneal dialysis catheter and solve the problem of broken peritoneal dialysis catheter during clinical use. Methods A total of 94 patients with end-stage renal disease who received newly opened peritoneal dialysis in the Department of Nephrology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2016 to December 2017 were selected as research objects. In order of the time of tube opening, 47 patients with singular ordinal number receiving treatment were set as the control group, and 47 patients with even ordinal number receiving treatment were set as the observation group. The patients of control group, using the traditional peritoneal dialysis tube nursing; the patients of observation group, using anti- broken peritoneal dialysis tube for nursing. To observe and compare the incidence of dialysis catheter loosening and breakage during dialysis in the 2 groups of peritoneal dialysis patients, as well as the patient satisfaction. Results The catheter crease deformation of the observation group(0 case) was significantly lower than that of the control group (12 cases), and the difference was statistically significant (χ2=13.610, P<0.05). The total satisfaction of patients in the observation group was 97.87％ (46/47), while that of patients in the control group was 72.34％ (30/47). The total satisfaction rate of observation group was significantly higher than that of control group (χ2=12.086, P<0.01). No leakage occurred in the observation group, which was also significantly lower than that in the control group. However, due to the limited observation time, the number of cases was small without statistical significance (P>0.05). Conclusions The improved peritoneal dialysis catheter is more convenient, safe and effective for long-term peritoneal dialysis patients, and it can reduce the incidence of peritonitis associated with peritoneal dialysis catheter, which is worthy of clinical application.

Development of single base extension-tags microarray for the detection of food-borne pathogens / 生物工程学报

We developed single base extension-tags (SBE-tags) microarray to detect eight common food-borne pathogens, including Staphylococcus aureus, Vibrio parahaemolyticus, Listeria monocytogenes, Salmonella, Enterobacter sakazaki, Shigella, Escherichia coli O157:H7 and Campylobacter jejuni. With specific PCR primers identified and integrated for eight food-borne pathogens, target sequences were amplified and purified as template DNA of single base extension-tags reaction. The products were hybridized to microarrays and scanned for fluorescence intensity. The experiment showed a specific and simultaneous detection of eight food-borne pathogens. The system limits is 0.1 pg for a genomic DNA and 5x10(2) CFU/mL for Salmonella typhimurium cultures. The single base extension-tags assay can be used to detect food-borne pathogens rapidly and accurately with a high sensitivity, and provide an efficient way for diagnosis and control of disease caused by food-borne pathogens.

Insulin resistance and hypertension / 华中科技大学学报（医学）（英德文版）

The insulin sensitivity in hypertensive patients with normal glucose tolerance (NGT), impaired glucose tolerance (IGT) and type 2 diabetes mellitus (DM) and the insulin resistance (IR) under the disorder of glucose metabolism and hypertension were studied. By glucose tolerance test and insulin release test, insulin sensitivity index (ISI) and the ratio of area under glucose tolerance curve (AUCG) to area under insulin release curve (AUCI) were calculated and analyzed. The results showed that ISI was decreased to varying degrees in the patients with hypertension, the mildest in the group of NGT with hypertension, followed by the group of IGT without hypertension, the group of IGT with hypertension and DM (P = 0). There was very significant difference in the ratio of AUCG/AUCI between the hypertensive patients with NGT and controls (P = 0). It was concluded that a significant IR existed during the development of IGT both in hypertension and nonhypertension. The increase of total insulin secretion (AUCI) was associated with nonhypertension simultaneously. IR of the hypertensive patients even existed in NGT and was worsened with the deterioration of glucose metabolism disorder, but the AUCI in the HT group changed slightly. A relative deficiency of insulin secretion or dysfunction of beta-cell of islet existed in IGT and DM of the hypertensive patients.
