Objective:To understand the current situation of nurses in 52 hospitals in China on mastery of knowledge about skin injury in the elderly based on the background of mixed-mode homogenization training.Methods:Using the convenient sampling method, a total of 1 067 nurses from 52 hospitals in China were selected as the research objects in January 2021. A self-designed questionnaire on knowledge of skin injury in the elderly was used to investigate the nurses through the questionnaire star and univariate analysis was used to analyze the influencing factors. A total of 1 067 questionnaires were distributed and 1 067 valid questionnaires were recovered, and the effective recovery rate was 100%.Results:The knowledge scores of pressure injury, incontinence-associated dermatitis, skin tear and xerosis cutis among 1067 nurses were (95.66±7.37) , (95.65±9.15) , (91.37±15.45) and (87.67±15.91) , respectively. The results of univariate analysis showed that hospital grade was the influencing factor of nurses' knowledge score of pressure injury, skin tear and incontinence-associated dermatitis ( P<0.05) , educational background was the influencing factor of nurses' knowledge score of skin tear ( P<0.05) , professional title was the influencing factor of nurses' knowledge scores of pressure injury, incontinence-associated dermatitis and xerosis cutis ( P<0.05) . Conclusions:Hospitals at all levels need to strengthen the theoretical and practical knowledge training for nurses on skin xerosis and skin tear in the elderly, especially for nurses with primary titles and lower education in grassroots hospitals.

Background: Type 2 diabetes (T2DM) patients are susceptible to Helicobacter pylori (HP), and it has been reported that the occurrence of proteinuria is associated with HP infection in T2DM patients; however, this view remains controversial. This meta-analysis aimed to explore the association between HP infection and the occurrence of proteinuria in T2DM patients. In addition, we hope to provide some recommendations to readers in clinical or related fields. Methods: Our meta-analysis was conducted with the methodology of the Cochrane Collaboration. Search strategies were formulated by relevant professionals. Case-control studies that compared the occurrence of proteinuria in T2DM patients with and without HP infection were involved in our meta-analysis. Relevant English or Chinese studies were searched on online databases before 2018, including PubMed, the Cochrane library, Medline, Google Scholar, the China National Infrastructure, and Wanfang database. The search strategies were "diabetic proteinuria, diabetic microalbuminuria, diabetic albuminuria, diabetic kidney disease, diabetic renal dysfunction, diabetic renal disease, diabetic nephropathy, diabetic complications, and diabetic mellitus, combined with HP." The quality of these involved articles was separately assessed by two investigators using the Newcastle-Ottawa Scale (NOS). Odds ratios (ORs) and associated 95% confidence intervals (CIs) were extracted and pooled using fixed-effects models. Results: Seven studies involving 1029 participants were included. The quality of these seven articles was all above five stars as assessed by NOS, and there was no significant publication bias in our meta-analysis. We found that T2DM patients with HP infection had a 2.00 times higher risk of the occurrence of proteinuria than patients without HP infection (OR: 2.00, 95% CI: 1.48-2.69). Conclusions Our analysis showed that HP infection was associated with the occurrence of proteinuria in T2DM patients. HP radical surgery might be a therapeutic option for protecting kidney function in patients with T2DM.

Objective·To evaluate the value of texture analysis in the discrimination of colorectal cancer (CRC) and ulcerative colitis (UC). Methods?·?The CT images of 61 CRC patients, 62 UC patients and 42 control objects were retrospectively analyzed. All the patients were pathologically proved and performed triphasic contrast-enhanced CT scan: non-enhanced phase (NP), the arterial phase (AP) and the enteric phase (EP). The region of interest was drawn along the abnormal bowel wall’s edge in each scan phase and texture features were generated by MaZda software. Based on 3 texture feature selection methods, the optimal subsets were generated and analyzed by 6 texture feature classification methods. The results were shown by misclassification rate (MCR). To compare the performance of texture-based classification and human visual classification, two radiologists with more than 10 years of gastrointestinal disease diagnostic experience analyzed the data. Results?·?The texture analysis based average MCR of differentiation between CRC and UC was (28.42±6.89)%, (28.19±4.07)%, (19.10±3.58)% in NP, AP, EP respectively. Compared with other texture feature classification methods, nonlinear discriminant analysis (NDA) was more accurate. In EP, NDA achieved an excellent classification result (MCR=12.61%). The average MCR between CRC and normally dilated bowel wall (NOR) was (13.33±7.21)%, (15.49±5.47)%, (6.74±3.02)%, while the average MCR between UC and NOR was (19.26±4.68)%, (20.04±6.63)%, (16.74±6.36)% in NP, AP and EP respectively. For visual classification between CRC and UC, the average MCR was (40.48±3.21)%, (35.71±1.60)%, (26.43±1.15)% in NP, AP, EP respectively. But the MCR of texture classification was lower than that of human vision classification, and computer texture classification had higher differential diagnosis rate. Conclusion?·?The CT-based texture analysis could be a feasible supplementary method to differentiate CRC from UC. NDA is more accurate than other classification methods, especially in EP.

Objective To explore the efficacy and safety of thymalfasin in the treatment of severe pulmonary infection after liver transplantation.Methods Twenty seven patients who developed severe lung infection after undergoing liver transplantation in Organ Transplant Institute of the 309 th Hospital of People’s Liberation Army from January 2008 to May 2014 were enrolled in this study.According to whether the application of thymalfasin,the patients were divide into thymalfasin group (n =11)and control group (n =16).In the thymalfasin group,thymalfasin was administered via subcutaneous injection at a dose of 1.6 mg once daily for consecutive two weeks.In the control group,conventional anti-infection therapy was delivered. Ventilator time,duration of fever,the length of intensive care unit (ICU)stay and mortality were statistically compared between two groups.And the incidence of acute rejection (AR)was monitored.Results Ventilator time,duration of fever,length of ICU stay of patients in the thymalfasin group were significantly shortened compared with those in the control group (all in P <0.05).There was no significant difference in the mortality between two groups.No clinical AR was observed in either group.No thymalfasin-related adverse event was found in the thymalfasin group.Conclusions Thymalfasin can improve the curative effect to anti-infection of patients with severe pulmonary infection after liver transplantation without the incidence of AR,which is efficacious and safe in the treatment of severe pulmonary infection.

OBJECTIVETo observe the effect of Compound Shenhua Tablet (, SHT) on the sodium-potassium- exchanging adenosinetriphosphatase (Na(+)-K(+)-ATPase) in the renal tubular epithelial cells of rats with acute ischemic reperfusion and to investigate the mechanisms underlying the effects of SHT on renal ischemic reperfusion injury (RIRI).

METHODSFifty male Wistar rats were randomly divided into the sham surgery group, model group, astragaloside group [150 mg/(kg·d)], SHT low-dose group [1.5 g/(kg·d)] and SHT high-dose group [3.0 g/(kg·d)], with 10 rats in each group. After 1 week of continuous intragastric drug administration, surgery was performed to establish the model. At either 24 or 72 h after the surgery, 5 rats in each group were sacrificed, blood biochemistry, renal pathology, immunoblot and immunohistochemical examinations were performed, and double immunofluorescence staining was observed under a laser confocal microscope.

RESULTSCompared with the sham surgery group, the serum creatinine (SCr) and blood urea nitrogen (BUN) levels were significantly increased, Na(+)-K(+)-ATPase protein level was decreased, and kidney injury molecule-1 (KIM-1) protein level was increased in the model group after the surgery (P<0.01 or P<0.05). Compared with the model group, the SCr, BUN, pathological scores, Na(+)-K(+)-ATPase, and the KIM-1 protein level of the three treatment groups were significantly improved at 72 h after the surgery (P<0.05 or P<0.01). And the SCr, BUN of the SHT low- and high-dose groups, and the pathological scores of the SHT high-dose group were significantly lower than those of the astragaloside group (P<0.05). The localizations of Na(+)-K(+)-ATPase and megalin of the model group were disrupted, with the distribution areas overlapping with each other and alternately arranged. The severity of the disruption was slightly milder in three treatment groups compared with that of the model group. The results of immunofluorescence staining showed that the SHT high-dose group had a superior effect as compared with the astragaloside group and the SHT low-dose group.

CONCLUSIONSThe SHT effectively alleviated RIRI caused by ischemic reperfusion, promoted the recovery of the polarity of renal tubular epithelial cells, and protected the renal tubules. The therapeutic effects of SHT were superior to those of astragaloside as a single agent.

OBJECTIVETo investigate the impact of a traditional Chinese medicinal compound known as Fufang Shenhua Tablet (SHP) on the expression of Toll-like receptors (TLRs) during renal ischemia-reperfusion injury (IRI)-induced acute kidney injury (AKI) in rats.

METHODSA total of 28 Wistar rats were randomly divided into five groups: (1) pseudo-operation control group, (2) ischemia-reperfusion model group, (3) Astragaloside group, (4) high-dose SHP group, and (5) low-dose SHP group. There were four rats in the pseudo-operation group and six rats in each of the other groups. The accepted ischemia-reperfusion model was established after a 7-day gavage intervention, and pathological changes and renal function were observed, using an enzyme-linked immunosorbent assay (ELISA) to detect interleukin 8 (IL-8) and interferon gamma (IFN-γ) levels, as well as immunohistochemical staining to detect altered levels of TLR2 and TLR4 expression in renal tissue.

RESULTSAfter 24 h, renal pathological damage and the expression levels of serum creatinine (Scr), IL-8, IFN-γ, TLR2, and TLR4 were significantly higher in the model group as compared with the pseudo-operation group (P<0.05). In addition, at 24 h the above indicators decreased significantly in the Astragaloside group, high-dose SHP group and low-dose SHP group as compared with the ischemia-reperfusion model group (P< 0.05). TLR2 and TLR4 expression levels were significantly reduced in the SHP treatment and Astragaloside group as compared with the pseudo-operation group (P<0.05). Further, the high-dose SHP group showed significantly less renal damage score and decreased levels of TLR expression than those of low-dose SHP group and Astragaloside group (all P<0.05).

CONCLUSIONSHP can alleviate the renal structural and functional damage caused by IRI-induced AKI in rats by reducing the damage of renal pathology, which may reduce inflammatory cytokine levels by downregulating the expression of TLRs in renal tissue in a dose-dependent manner.

OBJECTIVETo investigate the mechanism of anti-death receptor 5-10 (AD5-10) combined with epirubicin in treating rheumatoid arthritis (RA).

METHODSWe detected the cell viability of the fibroblast-like synoviocytes (FLS) from RA patients with MTT. The expression level of apoptosis signaling pathways protein, p53, and p21 were evaluated with Western blot.

RESULTSWe found that epirubicin, at different doses, could enhance the effect of AD5-10 on FLS, promoting the apoptosis of FLS. The expression levels of caspase-3, -8, -9, c-FLIP, Bcl-2, p53, and p21 in the FLS changed after epirubicin treatment.

CONCLUSIONEpirubicin may coordinate with AD5-10 in inducing FLS apoptosis through affecting the levels of p53, p21, c-FLIP, and Bcl-2.

OBJECTIVETo investigate the effect of aging on the expressions of monocyte chemoattractant protein 1 (MCP-1) and intercellular adhesion molecule 1 (ICAM-1) in the lung tissue of rats with lipopolysaccharide (LPS)-induced acute lung injury (ALI).

METHODSBoth young (3 months old) and aged (27 months old) female Wistar rats were randomly divided into two groups (n=8), namely the normal control and LPS-induced ALI groups. Immunohistochemistry for of ED-1 was used to detect the infiltrating inflammatory cells. Western blot and Northern blot analyses were employed for evaluating the expressions of MCP-1 and ICAM-1 at the protein and mRNA levels.

RESULTSVirtually no ED-1-positive cells were found in the lung tissue of the control rats in the young and aged groups. After LPS-induced ALI, ED-1-positive cells in the lung tissues increased significantly in both young and aged groups (P<0.05), and the increment was more obviously in the aged group (P<0.05). In the two normal control groups, the aged rats showed significantly higher expressions of MCP-1 and ICAM-1 than the young rats (P<0.05); LPS significantly up-regulated their expression in the young and aged groups (P<0.05), but the latter showed greater increments (P<0.05). The aged rats with ALI also showed significantly greater MCP-1 and ICAM-1 increments than those of the young rats (P<0.05).

CONCLUSIONSAging may upregulate lung MCP-1 and ICAM-1 expressions and enhance LPS-induced increments of MCP-1 and ICAM-1 expressions to exacerbate the pulmonary inflammation in rats.

Objective To investigate liver and kidney lesions in HBV-GN patients and relationship between them and provide evidences to make early diagnosis of HBV-GN. Methods Reviewing the clinicopathological and laboratory indexes of 205 patients with HBV-GN diagnosed by renal biopsy in our hospital from Semptember 1995 to November 2008. Results HBV-GN account for 5.6% of all renal biopsies at the same time. Among them, 157 (76. 5% ) patients were male, 123 (60%)was 19-45 years-old.95(46% )patients break out with kidney disease. HBsAg, HBeAg, HBcAg were the most common HBV makers. 102(49.8% ) patients present nephrotic syndrome, 18(8.8% ) suffered kidney dysfunction; 18 patients with hepatic cirrhosis. Patients with or without liver disfunction got no different in clinic manifestation and renal pathology. With the rising of the content of HBV-DNA in surum,the urinary protein increases.Renal data shows that membranous nephropathy(MN) was the most frequent type(60. 5% ). Conclusion males. Nephrotic syndrome was the most common clinic manifestation and membranous nephropathy was the most common pathology. 10% persent patisnts had loss of renal function at the time of renal biopsy. The HBV copies in serum correlated with the albuminuria. HBV-GN patients had desynchroneity lesions in kidney and liver. As the high rate of HBV infection in China, It needs to prevent the kidney damage in HBV infecious people and to elevate early diagnosis and therapy.
