Objective To study the coping strategies of patients with mood disorders and explore the corresponding nursing strategies.Methods A survey,using the coping strategies questionnaire,was conducted among 32 patients with unipolar disorder and 55 patients with bipolar disorder including 34 with current depressive episode,14 with current manic episode and 7 with mixed episode.Results As for coping strategies,no difference was found between unipolar depression and bipolar disorder with current depressive episode or mixed episode(P>0.05);while significant difference was found between bipolar depression and bipolar mania on problem solving(t=-2.869,P=0.006),help seeking(t=-2.443,P=0.018),self accusation(t=2.461,P=0.018)and withdrawing(t=2.870,P=0.006).The patients with unipolar disorder,bipolar depressive or mixed episode tended to use mixed coping strategies,with the percentages of 50.00%,41.18%and 42.86%respectively and 64.29%of the patients with bipolar mania tended to use mature coping strategies.Conclusions Coping strategies of patients with mood disorder are associated with the status of the diseases but independent of the categories of the diseases.Therefore,the corresponding nursing strategies include setting aside the problems,encouraging family member to make decisions and conducting active guidance.

Objective To evaluate the diagnostic value of shear wave elastography on deep venous thrombosis in different stage.Methods Models of rabbits'deep venous thrombosis have been established to noninvasively measure Young's moduli of thrombosis in day 1 ,4,7,10 and 14 respectively by shear wave elastography.Results The elastic modulus of thrombosis increased with increment of the stages of thrombosis.Specifically,the mean Young's moduli of thrombosis increased from (4.0±1 .42)kPa (day 1)to (25.71 ±6.09)kPa (day 14),with statistical differences between each two observation time points (P <0.05).Conclusions Shear wave elastography can effectively reflect the elasticity of thrombosis in different stages,and the stage of thrombosis can be estimated judging by quantitative ultrasound elasticity preliminarily.

Objective To explore the antibacterial effect and mechanisms of platelets (PLT)on Staphylococcus epidermidis (SE).Methods Built infectious model of SE in vitro,whose final concentration was 105 CFU/ml in the reaction.Separately cocultured these models with PLT (the final concentration 400 × 109/L)-plasma (positive control)and BHI medium 12 hours later,and detected the antibacterial effect of PLT by making a liquid thinner and spreading counting method,and draw-ing antibacterial curve.Meanwhile,observed the bacterial structure by transmission electron microscope (TEM),and initially explored the antibacterial mechanism of PLT.Results The study showed the antibacterial effect of PLT on SE was very ob-vious,which appeared later than the plasma (M)group,but enduring.The images of TEM showed an electronlight region appeared in the centre of bacterium,contained condensed DNA molecules and leaded to slower fission.Conclusion PLT can damage the DNA structure of SE,and then affect the fission of SE,finally inhibit the proliferation of SE.

Objective:To assess the left ventricular (LV) myocardial mechanical dysfunction in patients with cirrhosis using ultrasonic layer-specific strain imaging and to explore its value in clinical application.Methods:A total of 80 consecutive cirrhosis patients without cardiovascular diseases were prospectively enrolled from October 2020 to March 2021 in Sichuan Provincial People′s Hospital, 39 of whom were assigned to the compensated group and 41 were assigned to the decompensated group according to the occurrence of portal hypertension. Forty-three healthy volunteers during the same period were randomly recruited as the control group. Transthoracic echocardiography was performed to assess the LV configuration and functional parameters. LV global longitudinal strain in endocardial, middle and epicardial myocardium (GLSendo, GLSmid, GLSepi), and longitudinal strain (LS) in basal, middle and apical segments, and peak strain dispersion (PSD) were obtained using ultrasonic layer-specific strain imaging. ΔLS was calculated by the formula of GLSendo-GLSepi. Then, the differences of related parameters among three groups were compared.Results:①Conventional echocardiography: compared with the control group, the interventricular septum end-diastolic thickness (IVSTd), left ventricular posterior wall end-diastolic thickness (LVPWd), left ventricular mass (LVM) and LVM index (LVMI) were increased in compensated and decompensated groups (all P<0.05), while no significant differences in conventional echocardiographic parameters were identified between the two cirrhosis groups (all P>0.05). ②Global layer-specific strain: compared with the control group, GLSendo, GLSmid, GLSepi and ΔLS were decreased and PSD was increased in compensated and decompensated groups (all P<0.05); Moreover, the decompensated group showed a more impaired GLSendo, GLSmid and GLSepi than compensated group (all P<0.05), whereas there were no significant differences of ΔLS and PSD between the two groups(all P>0.05). ③Segmental layer-specific strain: compared with the control group, LS values of three layers in compensated and decompensated groups were reduced at basal, middle and apical levels (all P<0.05); Compared with the compensated group, LS values of three layers in decompensated group tended to be reduced at above there levels, but only apical segments had significant differences (all P<0.05). Conclusions:There are different degrees of LV mechanical dysfunction in patients with variable severity of cirrhosis. Ultrasonic layer-specific strain imaging has the potential to quantitatively assess the state of cardiac involvement in patients with cirrhosis and to provide visual evidence for the early and accurate diagnosis of myocardial injuries.

Objective: To explore the value of bioelectrical impedance analysis in evaluating hemodialysis patients′ nutritional status. Methods: Cross-sectional design was employed to evaluate 193 hemodialysis patients′ nutritional status in a Level 3 hospital in Zhuhai, with bioelectrical impedance analysis, modified quantitative subjective global assessment, physical and biochemical measurement. The correlation between each index and the predictive effect of bioelectrical impedance analysis on malnutrition of patients were analyzed. Results: According to bioelectrical impedance analysis, hemodialysis patients′ average muscle mass was (44.06±8.84) kg, body fat rate was (19.81±8.89)%, fat free mass index was (17.70±2.45) kg/m², presumed bone mass was (2.49±0.46) kg, and extracellular water rate was (40.54±3.75)%. The bioelectrical impedance analysis indexes were significantly correlated with most other nutritional evaluation indexes (P<0.05). The muscle mass and bone mass of the malnourished group were lower than that of the well-nourished group (P<0.01). Multivariable logistic regression analysis found that body fat rate (OR=0.94, 95%CI 0.89-0.99), fat free body mass index (OR=0.79, 95%CI 0.66-0.93) were associated with lower risk of malnutrition, age (OR=1.08, 95% CI 1.04-1.12), dialysis age (OR=1.02, 95%CI 1.01-1.04), high sensitive C reactive protein (OR=1.11, 95%CI 1.03-1.23) were associated with higher risk of malnutrition. Conclusion Bioelectrical impedance analysis is a valid measurement on evaluating maintenance hemodialysis patients′ nutritional status. There has a high prevalence of malnutrition in hemodialysis patients. The lower risk of malnutrition is associated with higher body fat rate and higher fat free mass index, and the higher risk of malnutrition is associated with older age, longer dialysis age and higher level of high sensitive C reactive protein.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.
