ObjectiveTo observe the dynamic changes of plasma Clara cell secretory protein (CC16) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), and to explore its role in the occurrence and development of the disease and clinical significance.MethodsA total of 71 AECOPD patients were included in this study as observation group. All subjects completed the CAT questionnaire and were sampled 2 ml of venous blood on day 1 and day 7 after their admission. And the percentage of forced expiratory volume in the first second (FEV1%pred), percentage of forced vital capacity in the estimated value (FVC%pred), FEV1/FVC ratio, arterial partial pressure of carbon dioxide (PaCO2), white blood cell count (WBC), the proportion of neutrophils (NEUT%), C-reactive protein (CRP), procalcitonin (PCT) and the length of stay of subjects were recorded. Another 20 healthy adults were enrolled as the control group. Each subject of the control group was sampled 2 ml of venous blood. The plasma CC16 levels of the two groups were tested and compared, and analyzed its correlation with CAT score and length of stay.ResultsThe plasma CC16 level of AECOPD patients was significantly lower than that of the control group, lung function was significantly lower than that of the healthy control group, WBC and NEUT% were significantly higher than that of the healthy control group, and the difference was statistically significant (P<0.05). Compared with day 1 after admission, the plasma CC16 level, CAT score, PaCO2, WBC, NEUT%, CRP, PCT of AECOPD patients on day 7 were significantly decreased, with statistically significant differences (P<0.05). The plasma CC16 level of AECOPD patients was negatively correlated with their CAT score (r=–0.704, P<0.001), and also was negatively correlated with the length of stay (r=–0.351, P=0.003).ConclusionsCC16 is involved in the development and progression of AECOPD and closely related to the severity and prognosis of the disease. Its dynamic changes can predict the condition changes and evaluate the clinical treatment effect of patients with AECOPD. Combined with common clinical indicators, CC16 can shorten the length of stay of patients.
ObjectiveTo investigate the practice effect of WeChat on the treatment compliance of patients with hyperlipidaemia in general out-patient department. MethodsFrom June 2012 to May 2013, 178 patients with hyperlipidaemia who could use WeChat software were selected. The patients were randomly divided into the control group (87 patients) and experimental group (91 patients). All the patients were treatment with routine nursing intervention. The experimental group was giving nursing intervention based on WeChat. After 180 days, the compliance score and serum lipid level of the patient were tested and analyzed. ResultsThe score in experimental group on the treatment compliance were as follows:diet:6.57±0.78, take medicine:8.64±1.13, exercise:5.11±0.97, and return visit:5.75±0.74; the percentage effective control of lipid level was 93.4%. The score of the control group on the treatment compliance were as follows diet:4.63±1.23, take medicine:6.91±0.73, exercise:3.98±0.54, and return visit:4.86±0.39; the percentage effective control of lipid level was 57.5%. The difference in the results between two groups is significant (P<0.05). ConclusionApplying WeChat software on nursing intervention for patients with hyperlipidaemia may increase the treatment compliance and enhance the control of serum lipid level.
ObjectiveTo explore the best nursing interventions for advanced-age diabetes with pressure ulcer in Sichuan area. MethodsWe retrospectively analyzed the reasons for pressure ulcer and the nursing process for 37 patients with diabetes treated between March 2012 and March 2013 in our hospital. Then, we analyzed and summarized the susceptibility factors, wound nursing, nutritional support and blood sugar monitoring in all the patients. ResultsThrough intensive nursing, pressure ulcer in 36 patients were cured, and one patient died due to lung infection. ConclusionThe risk of pressure ulcer is high in advanced-age diabetes patients, and they need promising nursing. Individualized plan is necessary for them to improve their life-quality.
Objective To explore the application of WeChat software in the follow-up of patients with primary hypertension. Methods Seventy-two patients with primary hypertension treated between June and December 2014 were randomly divided into two groups, WeChat group and phone group, with 36 in each. The patients in both the two groups were followed up once a week for three months. We recorded patients’ blood pressure, heart rate, and body mass index (BMI), assessed their life style, and compared follow-up time, rate of readmission, satisfaction degree, medication compliance and follow-up loss rate between the two groups. Results There were no significant differences in blood pressure, heart rate and BMI between the two groups (P>0.05). At the end of the follow-up, there were no significant differences in blood pressure, heart rate, BMI, salt-intake compliance, medicine-intake compliance, patient satisfaction, follow-up loss rate, and readmission rate between the two groups (P>0.05), but patients in the WeChat group were less than those in the Phone group in terms of average weekly smoking, alcohol consumption, and follow-up time (P<0.05), and were better in terms of average weekly sport-time (P<0.05). Conclusion The application of WeChat software for follow-up in patients with primary hypertension can effectively improve the patients’ life style and follow-up efficiency.
The AC impedance of human hepatoma SMMC-7721 cells were measured in our laboratory by Agilent 4294A impedance analyzer in the frequency range of 0.01-100 MHz. And then the effect of hematocrit on electrical impedance characteristics of hepatoma cells was observed by electrical impedance spectroscopy, Bode diagram, Nyquist diagram and Nichols diagram. The results showed that firstly, there is a frequency dependence, i.e., the increment of real part and the imaginary part of complex electrical impedance (ΔZ', ΔZ″), the increment of the amplitude modulus of complex electrical impedance (Δ|Z*|) and phase angle (Δθ) were all changed with the increasing frequency. Secondly, it showed cell volume fraction (CVF) dependence, i.e., the increment of low-frequency limit (ΔZ'0, Δ|Z*|0), peak (ΔZ″p, Δθp), area and radius (Nyquist diagram, Nichols diagram) were all increased along with the electric field frequency. Thirdly, there was the presence of two characteristic frequencies: the first characteristic frequency (fC1) and the second characteristic frequency (fC2), which were originated respectively in the polarization effects of two interfaces that the cell membrane and extracellular fluid, cell membrane and cytoplasm. A conclusion can be drawn that the electrical impedance spectroscopy is able to be used to observe the electrical characteristics of human hepatoma cells, and therefore this method can be used to investigate the electrophysiological mechanisms of liver cancer cells, and provide research tools and observation parameters, and it also has important theoretical value and potential applications for screening anticancer drugs.
Objective To systematically review the correlation of activated partial thromboplastin time (APTT) and prognosis after ECMO treatment. Methods The PubMed, EMbase, MEDLINE, CNKI, WanFang Data and VIP databases were electronically searched to collect studies on the correlation of APTT and prognosis after ECMO treatment from database inception to April 11th, 2022. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4 software. Results A total of 22 studies, involving 2 913 patients were included. The level of APTT in the bleeding group was higher than that in the non-bleeding group during ECMO support treatment (MD=10.34, 95%CI 1.32 to 19.37, P=0.02). The APTT level in the thrombus group was lower than that in the non-thrombus group (MD=−3.58, 95%CI −5.89 to −1.27, P=0.002). The level of APTT in the death group was significantly higher than that in the survival group (MD=8.97, 95%CI 5.89 to 12.06, P<0.00001). Conclusion The APTT level of ECMO patients is closely related to the prognosis of bleeding, thrombosis and death. Due to the limited quantity and quality of the included studies, the above conclusion needs to be verified by more high-quality studies.
