ABSTRACT

The novel coronavirus 2019(2019-nCoV)was first detected from patients with pneumonia of an unknown cause in Wuhan in December 2019.It has since been confirmed as the pathogen for the new coronavirus pneumonia, recently named coronavirus disease 2019(COVID-19) by the WHO.Although the general population is commonly susceptible to the disease, infected elderly people show fast progression and severe manifestations with a high proportion in serious or critical condition as a result of compromised immunity and underlying diseases.In order to improve the quality of nursing management, reduce complications and decrease mortality for critically ill elderly patients, we assembled a national expert group with expertise in critical care nursing to write this consensus, based on a literature review and a subsequent panel discussion.The consensus covers the assessment, clinical nursing management, nursing care following hospital discharge and other aspects of care for critically ill elderly patients with COVID-19, aiming to share insights and provide guidance for clinical practice.

ABSTRACT

Objective To study the clinicopathological signiticance of the expression of musashi2 (MSI 2) protein and mRNA levels in human colorectal cancer (CRC).Methods The expression of MSI 2 protein in 85 CRC specimens and paired adjacent non-cancerous tissues were detected by immunohistochemistry (IHC).The relationship between the protein expression and clinicopatho]ogical features was analyzed.Immunoblotting and real time quantitative PCR were used to examine the expression of MSI 2 protein and mRNA levels in 12 paired fresh CRC and adjuvant non-cancerous tissues.Results MSI 2 overexpression was found in 45 cases of 75 CRC tissues,which was much higher than that in noncancerous tissues (59% vs.30%,P < 0.01).MSI 2 overexpression had a positive correlation with tumor size (x2 =7.682,P =0.006),T stage (x2 =4.218,P =0.040),Dukes stage (x2 =8.590,P =0.014),and Ki67 expression (x2 =6.412,P =0.011).Moreover,CRC patients with MSI 2 overexpression had a worse prognosis (x2 =4.855,P =0.028).Both MSI 2 protein and mRNA levels in 12 cases of CRC tissues were much higher than that in non-cancerous tissues (t =3.323,P < 0.01;t =2.673,P =0.022,respectively).Conclusion MSI 2 overexpression is closely related with tumor size,T stage,Dukes stage,Ki67 expression and poor prognosis of CRC patients.

ABSTRACT

PURPOSE: To investigate the effects of hyperbaric oxygen (HBO) pretreatment on cognitive decline and neuronal damage in an Alzheimer’s disease (AD) rat model. MATERIALS AND METHODS: Rats were divided into three groups: normal saline (NS), AD, and HBO+AD. In the AD group, amyloid β peptide (Aβ)₁₋₄₀ was injected into the hippocampal CA1 region of the brain. NS rats received NS injection. In the HBO+AD group, rats received 5 days of daily HBO therapy following Aβ₁₋₄₀ injection. Learning and memory capabilities were examined using the Morris water maze task. Neuronal damage and astrocyte activation were evaluated by hematoxylin-eosin staining and immunohistochemistry, respectively. Dendritic spine density was determined by Golgi-Cox staining. Tumor necrosis factor-α, interleukin-1β, and interleukin-10 production was assessed by enzyme-linked immunosorbent assay. Neuron apoptosis was evaluated by terminal deoxynucleotidyl transferase dUTP nick end labeling. Protein expression was examined by western blotting. RESULTS: Learning and memory dysfunction was ameliorated in the HBO+AD group, as shown by significantly lower swimming distances and escape latency, compared to the AD group. Lower rates of neuronal damage, astrocyte activation, dendritic spine loss, and hippocampal neuron apoptosis were seen in the HBO+AD than in the AD group. A lower rate of hippocampal p38 mitogen-activated protein kinase (MAPK) phosphorylation was observed in the HBO+AD than in the AD group. CONCLUSION: HBO pretreatment improves cognition and reduces hippocampal damage via p38 MAPK in AD rats.

ABSTRACT

Objective:To explore the effect of microRNA-101 on apoptosis of condylar cartilage cells and the specific mechanism of molecular biology. Methods: IL-1 was used to stimulate and establish the model of apoptosis of condylar cartilage cells. The expression change of miR-101 in control group was compared with that in IL-1 stimulation group by qRT-PCR. Overexpression and down-regulation models of miR-101 were established by transfecting Mimics and Inhibitor and verified by qRT-PCR. Flow cytometry was used to detect the effect of miR-101 overexpression and down-regulation on apoptosis. Target gene of miR-101 was analyzed and calculated through bioinformatics. Western blot and Luciferase report assay were used to detect whether Sox9 could become the target gene of miR-101. Results:qRT-PCR results showed that IL-1 stimulation could cause the increase of miR-101 expression. After the transfection of rabbit condylar cartilage cells by Mimics and Inhibitor, qRT-PCR results confirmed the significant effect of miR-101 overexpression and down-regulation. It was confirmed by flow cytometry that overexpression of miR-101 could promote the apoptosis of condylar cartilage cells, and down-regulation of miR-101 could reduce the apoptosis. It was confirmed by Western blot and Luciferase report assay that Sox9 was the target gene of miR-101, and miR-101 inhibited SOX9 expression through complementary pairing with 3’UTR of Sox9 mRNA. Conclusions:miR-101 can promote the apoptosis of condylar cartilage cells through inhibiting the protein level of target gene SOX9.

Methods A total of 1536 adult residents were selected by using cluster sampling method, and 1496 completed the questionnaire survey. Blood pressure was measured for each participant. Results The prevalence of hypertension was 31.1%. Higher prevalence of hypertension was found in male ( 42. 0% vs 24. 5%, P < 0. 05 ) and the elderly. No statistically significant difference of prevalence of hypertension was investigated in different nationalities (P > O. 05 ). Conclusion The prevalence of hypertension among adult residents in Mongolian region of Hulunbeier is relatively higher.

ABSTRACT

Objective To investigate the prevalence of hypertension and its related factors in Hulunbeier Mongolian region. Method A stratified multistage sampling was used to select residents aged 18 and over in a town of Hulunbeier region. 453 persons served as subjects for this questionnaire survey. Their blood pressure, height, weight, waist circumference were measured and body mass index (BMI) were calculated. Then an analysis of the prevalence of hypertension and its related risk factors were performed. Results The hypertension prevalence rate was 34.5%, the standardized rate was 45.4%, and the prevalence in men (48.9%) was significantly higher than that in women (25.4%) (P50 (OR=11.312, 95%CI 4.309~22.132), BMI (2.255, 1.180~4.311), gender (OR=2.788, 1.461~5.323) and drinking (2.306, 1.287~4.134) were significantly related to hypertension. Conclusion The standardized prevalence of hypertension in Hulunbeier Mongolian region is higher than the average prevalence in China, 2002. Old age, abdominal obesity, overweight or obesity, male and alcohol drinking were the main risk factors for hypertension in this region. The government and the health sector should strengthen the health education of healthy lifestyle and health promotion and the control.

ABSTRACT

Objective To determine the contents of lutein,zeaxanthin and ?-carotene in 31 vegetables.Method High performance liquid chromatography method with Develosil C30 column and ultraviolet detector was used to detect lutein,zeaxanthin and ?-carotene at wavelength of 480nm.A gradient elution method with elution A (acetonitrile:methol=75:25) and B (methyl-tert-butyl-ether) was used to separate the carotenoids in both raw and cooked vegetables.Results The retention time of lutein,zeaxanthin and ?-carotene was 10.355,10.732 and 20.789 min respectively.The contents of lutein,zeaxanthin and ?-carotene were linearly related with the peak area.Analysis showed that dark leafy vegetable such as amaranth,Chinese celery leaf,parsley,spinach and pakchoi petiole contained the highest amount of lutein.Zeaxanthin was detected only in dehydrated daylily.There was little or no loss of lutein,zeaxanthin and ?-carotene but an average increase in lutein and ?-carotene in vegetables after cooking.Conclusion Vegetables,especially dark leafy vegetables are major sources of dietary lutein,and ?-carotene.Consuming cooked vegetables tends to increase the intakes of lutein,zeaxanthin and their bioavailability.
