Objective: To explore the impacts of vitamin D deficiency on early carotid elasticity in patients with type 2 diabetes mellitus (T2DM) using ultrafast pulse wave velocity (UFPWV) technique. Methods: A total of 92 patients with T2DM were enrolled (T2DM group) and divided into vitamin D deficiency subgroup and vitamin D non-deficiency subgroup according to the level of 25-hydroxyvitamin D3 (25[OH]D3), while 1 544 normal adults were taken as controls(control group). UFPWV technique was used to measure carotid elasticity parameters, including pulse wave velocity at the beginning of systole (PWV-BS) and the end of systole (PWV-ES), and clinical data and laboratory indicators of both groups were collected. Then statistical analysis of the above data was performed. Results: ①Among T2DM group, the levels of body mass index (BMI), fasting blood glucose (FPG), systolic blood pressure, diastolic blood pressure, total cholesterol (TC), triglyceride, PWV-BS and PWV-ES of vitamin D deficiency subgroup were higher than those of non-deficient subgroup (all P<0.05), while the level of high density lipoprotein cholesterol (HDL-C) was lower than that of the vitamin D non-deficient subgroup (P<0.05). ②Pearson correlation analysis showed that PWV-BS and PWV-ES were positively correlated with age, BMI, FPG, systolic blood pressure, diastolic blood pressure and TC (all P<0.05) but negatively correlated with 25(OH)D3 and HDL-C (P<0.05). ③Multivariate linear stepwise regression analysis showed that FPG, systolic blood pressure, age and TC were risk factors for PWV-BS and PWV-ES (all P<0.05), whereas 25(OH)D3 was a protective factor for PWV-ES (P<0.05). Conclusion: PWV-BS and PWV-ES values in T2DM patients with vitamin D deficiency significantly elevated. Vitamin D may be a protective factor for carotid elasticity in patients with T2DM. Monitoring vitamins level in T2DM patients is promptly supplemented. Vitamin D may delay the development of T2DM complications.

Objective To investigate the drug resistance characteristics and epidemic trend of Escherichia coli in Anning, Yunnan, and to provide a reference for clinical rational use of antibiotics. Methods A total of 376 strains of Escherichia coli were isolated from June 2018 to June 2019 from Kungang Hospital of Yunnan Province. The ESBLs producing strains were screened by double disk method and the sensitivity of ESBLs to antibiotics was detected by K-B method. The genotyping of ESBLs strains and the class I, II and III integrase genes in integron 3^' and 5^' conservative regions was conducted using polymerase chain reaction (PCR). Results The detection rate of ESBLs producing Escherichia coli was 53.19% (200/376). ESBLs-producing Escherichia coli had a low resistance rate to carbapenem antibacterial drugs with a relatively high sensitivity. The resistance rates to amikacin and piperacillin were 7.50% and 12.50% respectively, which had good antibacterial activity. The resistance rate to other antibiotics was high. There were 74.00% (148/ 200) of ESBLs-producing Escherichia coli carrying CTX-M gene, 34.50% (69/200) carrying TEM genes, and 1.00% (2/200) of strains carrying SHV genes. In addition, there were 9.00% (18/200) of strains carrying both CTX-M and TEM genes, and 0.50% (1/200) of strains carrying both CTX-M and SHV genes. The detection rate of integrons accounted for 37.00% (74/200), all of which were class I integrons. Conclusion The prevalence of ESBLs-producing Escherichia coli was relatively high in Anning, Yunnan. ESBLs-producing Escherichia coli showed a trend of multi-drug resistance. The genotype was mainly CTX-M, and the integron was classified as class I.

OBJECTIVETo discuss the relationship between the onset of peptic ulcers (PU) and meteorological factors (MF).

METHODSIn reviewing records from 17 hospitals in the city of Nanning from 1992 to 1997, we found 24, 252 cases of PU in 104, 121 samples of gastroscopic examinations. We then calculated the detectable rate of PU (DRPU) during each season every five days (FD) and made a correlated analysis with the seasonal MF during the same period in Nanning. Finally, we made a multiple regressive correlated analysis of DRPU and the 5MF for the same period of the year. A forecast model based on the MF of the previous FD was established. The real value and the forecast value was being tested and verified.

RESULTSFrom 1992 to 1997, the DRPU is: winter and spring > summer and autumn (P < 0.005). There is a close relationship between the DRPU and the average temperature (AT), the average highest temperature (AHT), the average lowest temperature (ALT), average air pressure (AAP) and the average dew point temperature (ADT) of the five days of the same period of the year (the correlated coefficients are -0.5348, -05167, -0.5384, 0.4579 and -0.4936, respectively), with P < 0.01. The AT, AHT, ALT, AAP and ADT of the previous FD are of great value in forecasting the onset of PU, with its real value and forecast value corresponding to 66.6%.

CONCLUSIONSThere exists a close relationship between DRPU and the AT, AHT, ALT, AAP and ADT of the FD for the same period. A mid-term medical meteorological forecast of the onset of PU can be made more accurately and reliably according to the close relation between the DRPU and some MF of the previous FD.

Objective:To identify the key convergence points in the medical-nursing combined care among literature, and establish a mechanism for medical-nursing combined care integration from the perspective of the synergy theory, for the purpose of promoting the integrated development of such care in China.Methods:Relevant literature on the medical-nursing combined care were retrieved from the CNKI database from September 2013 to September 2021. The search formula used was TI= "the medical-nursing care integration" AND SU=(convergence+ transformation+ coordination+ mechanism), while supplementary searches were made using " pkulaw.com database" and Baidu Scholar database. The method of literature content analysis was used to screen key points of the medical-nursing combined care, and the convergence mechanism was built based on the perspective of the synergy theory.Results:A total of 42 literatures were included in this study, 8 key convergence points of medica-nursing combined care integration were identified. Namely the 4 key horizontal convergence points of medical care, aging care, rehabilitation and nursing, the 3 key vertical convergence points of home care, institution care and community care, and the one key convergence point of institutional medical care. Based on the synergy theory and the 8 key convergence points, the " 431" convergence mechanism of medical-nursing combined care was constructed. This mechanism refered to the horizontal linkage of healthcare, nursing, rehabilitation and aging care, the vertical redirection among home care, institution care and community care modes, and the development mode focusing on institutional aging care.Conclusions:At present, the poor convergence between aging care and nursing care in China is a key roadblock hindering the integrated development of aging and nursing care. Medical-nursing combined care should be conducive to the " 431" convergence development, achieving horizontal linkage, vertical redirection, and resource sharing, for the purpose of high-quality development of China′s aging care system.

Objective:To evaluate the efficacy and safety of lactulose combined with polyethylene glycol for bowel preparation before colonoscopy in patients of different risks.Methods:A total of 208 patients undergoing colonoscopy were enrolled, including 108 high-risk and 100 low-risk patients. The high-risk patients were divided into group A (54 taking lactulose + polyethylene glycol) and group B (54 taking polyethylene glycol), and the low-risk patients were divided into group C (49 taking lactulose + polyethylene glycol) and group D (51 taking polyethylene glycol). The Boston bowel preparation score, cecal intubation time, withdrawal time, the detection rate of colonic polyps and adenoma, and the incidence of adverse reactions were observed.Results:Among the high-risk patients, the Boston bowel preparation score and adenoma detection rate in group A [(6.35±1.15) scores, 46.3%] were significantly higher than those in group B [(5.76±0.89) scores, 22.2%, both P<0.05], and the first defecation interval in group A was significantly shorter than that in group B [(1.20±0.85) h VS (3.29 ± 2.93) h, P<0.05]. There was no significant difference in adequate bowel preparation rate, polyp detection rate, frequency of defecation or incidence of adverse reactions between group A and B. In the low-risk patients, the first defecation interval in group C was significantly shorter than that in group D [(1.65 ± 1.35) h VS (3.42 ± 2.64) h, P<0.05], and the incidence of adverse reactions was significantly lower than that in group D (44.9% VS 64.7%, P<0.05). There was no significant difference in adequate bowel preparation rate, Boston bowel preparation score, adenoma detection rate, polyp detection rate or frequency of defecation between group C and D. Conclusion:For the high-risk patients, the effect of lactulose combined with polyethylene glycol for bowel cleansing is better than that of traditional polyethylene glycol in the improvement of the Boston bowel preparation score, adenoma detection rate, and the first defecation interval. For low-risk patients, lactulose combined with polyethylene glycol regimen has few advantages over traditional polyethylene glycol regimen.

BACKGROUND: Meshes play a crucial role in hernia repair. However, the displacement of mesh inevitably leads to various associated complications. This process is difficult to be traced by conventional imaging means. The purpose of this study is to create a contrast-enhanced material with high-density property that can be detected by computed tomography (CT). METHODS: The contrast-enhanced monofilament was manufactured from barium sulfate nanoparticles and medical polypropylene (PP/Ba). To characterize the composite, stress tensile tests and scanning electron microscopy (SEM) was performed. Toxicity and biocompatibility of PP/Ba materials was verified by in vitro cellular assays. Meanwhile, the inflammatory response was tested by protein adsorption assay. In addition, an animal model was established to demonstrate the long-term radiographic effect of the composite material in vivo. Subsequent pathological tests confirmed its in vivo compatibility. RESULTS: The SEM revealed that the main component of the monofilament is carbon. In vitro cell experiments demonstrated that novel material does not affect cell activity and proliferation. Protein adsorption assays indicated that the contrast-enhanced material does not cause additional inflammatory responses. In addition, in vivo experiments illustrated that PP/Ba mesh can be detected by CT and has good in vivo compatibility. CONCLUSION These results highlight the excellent biocompatibility of the contrast-enhanced material, which is suitable for human abdominal wall tissue engineering.
