Unless otherwise indicated, reagents and materials used in the following examples are commercially available.

Example 1

1. Data and Experimental methods

1.1 study object

This study retrospectively analyzed 131 patients with Sars-cov-2 infection from 1 month to 5 months of 2020, 14 asymptomatic patients according to the national health and wellness committee "protocol for prevention and treatment of new coronary pneumonia" (6 th edition), 12 light patients, 34 general patients, and 18 severe/critical patients according to the new guidelines for diagnosis and treatment of coronavirus, and 33 convalescent patients according to the standard for discharge from convalescence prescribed by the guidelines. 20 healthy control samples were from the university of medicine, cis-de hospital, guangzhou. Samples are collected in early stage of diseases, and the collection time of the samples of patients in the rehabilitation group is from three days before discharge to 20 days after discharge.

1.2 antibody array Q440

COVID19 Cytokines adopts Riboao QAH-CAA-440 protein chip to measure the level of biomarkers in 131 serum samples, and the levels of COVID19 serum Cytokines of different typing patients in the samples are analyzed and observed.

Specifically, protein screening was performed using a cytokine array Q440(QAH-CAA-440, RayBiotech, Inc, Peachtree Corners, GA, USA) that can quantitatively detect 440 kinds of human serum proteins. Antibody array manipulations were performed exactly according to the manufacturer's instructions. Briefly, the array was dried at room temperature for 2 hours, then plugged by adding 100 μ l of 2-fold diluted sample diluent to each well, and after 30 minutes the sample diluent was aspirated. Mu.l of 2-fold diluted serum samples were added to each well and incubated overnight at 4 ℃. The slides were washed 5 times for 5min with wash buffer I and then 3 times for 5min with wash buffer II. Wash buffer was blotted dry and 80ul biotin-conjugated antibody mix was added to each well and incubated for 2 hours at room temperature. After washing the array, 80ul of AlexaFluor 555-conjugated streptavidin was added to each well and incubated for 1 hour at room temperature in the absence of light. Finally, the signal was scanned and extracted using an InnoScan310 scanner (Innopsys, carbone, france).

1.3 statistical analysis

And determining the influence of the controllable factors on the research result by analyzing the contribution of the variation from different sources to the total variation in the research. Differentially Expressed Proteins (DEP) are defined as p-values (p. val) less than 0.05 and foldchange greater than 1.2 or less than 0.83(absolutelogFC > 0.263). All statistics were analyzed using R software (version 3.6.3).

Principal component analysis and hierarchical clustering analysis are based on differences in protein expression patterns to analyze differences between different sets of samples and proteins. GO analysis and KEGG enrichment analysis determined significant enrichment of protein function and signaling pathways with p values < 0.05. PCA (R package "ggbilot"), hierarchical cluster analysis (R package "gplots"), KEGG enrichment analysis (R package "clusterProfiler"), and GO enrichment analysis (R package "org.hs.e.db" and "clusterProfiler") were analyzed using R software (version 3.6.3). An ROC curve is constructed by using an R software package 'pROC', and the diagnostic value of the protein to different stages and different symptoms of COVID-19 is evaluated.

2. Results of the experiment

The statistical data are shown in Table 1

TABLE 1

2.1 pairwise differential comparisons between groups, Differentially Expressed Proteins (DEPs) were defined as p-value (P.Val) less than 0.05, foldchange greater than 1.2, or less than 0.83(absolutelogFC > 0.263). 160 proteins which are different between a healthy control group and a heavy group are screened out in the experiment; 56 differential proteins between the asymptomatic group and the heavy group; there were 107 differential proteins between the light and heavy groups; there were 60 differential proteins between the normal and heavy groups; there were 88 different proteins between the convalescent group and the heavy group.

Making a Wein diagram of the differential proteins of the screened heavy type group, the screened asymptomatic group, the screened light type group and the screened common type group respectively to obtain 8 overlapped cytokines, wherein the overlapping cytokines comprise: eotaxin-2, IP-10, IL-18Rb, IL-18, OPN, IL-2Rb, GDF-15, IL-12p 40. See fig. 1.

Simultaneously, 71 cytokines unique to healthy control groups and heavy groups, 15 cytokines unique to asymptomatic groups and heavy groups, 41 cytokines unique to light groups and heavy groups, 8 cytokines unique to common groups and heavy groups and 28 cytokines unique to convalescent groups and heavy groups are obtained.

2.2A trend graph was made using the expression levels of 8 proteins overlaid to observe cytokine expression at different severity of disease, see FIG. 2.

2.3 GO and KEGG analysis of protein function with R software package "clusterProfiler". KEGG analysis shows that the differential factors are mainly enriched in pathways such as 'interaction of cytokines and receptors thereof', 'Toll-like receptor signal pathway', 'interaction of viral proteins and cytokines and receptors thereof', and the like, which are shown in figure 3. GO analysis shows that the differential factors are mainly involved in biological processes such as 'T cell and NK mediated immune response' (figure 4), and play a role in regulating 'activity and binding of cytokines and receptors thereof' (figure 5). The cytokine function is shown in table 2.

TABLE 2

2.4 Using the R software package "pROC", we constructed ROC curves and calculated the area under the ROC curve (AUC). For both the patients with severe and non-severe symptoms, GDF-15(AUC 0.887), IP-10(AUC 0.858), OPN (AUC 0.858), Eotaxin-2(AUC 0.798), IL-18(AUC 0.792), IL-12p40(AUC 0.728) had better diagnostic efficacy, as shown in fig. 6.

(5) the cytokine marker combination for distinguishing severe cases and rehabilitation of the novel coronavirus pneumonia and evaluating the curative effect is selected from one or more of the following cytokines:

more importantly, based on the above results, the invention provides a novel coronavirus pneumonia severe illness and curative effect evaluation system, which comprises a preset value module, a data collection module, a data storage module, a data processing module and a result display module;

(1) the preset value module comprises concentration values of the cytokine markers corresponding to severe cases and non-severe cases:

cytokine (pg/ml) Severe illness Non-severe disease
IP-10 1657.431 858.5427
OPN 44767.89 20083.95
IL-2Rb 505.336 1955.144
IL-18Rb 46.04179 727.1648
IL-18 8821.305 2679.998
GDF-15 589.8844 167.732
Eotaxin-2 62.98553 126.6738
IL-12p40 36.44589 118.7969

(2) The data collection module comprises a data monitoring module and/or a data entry module and is used for collecting and/or entering the concentration value of the cytokine marker;

(3) the data storage module is used for storing the information of the data collection module;

(4) the data processing module is used for comparing the information of the preset value module and the data collecting module;

(5) and the data display module is used for displaying the result of the data processing module.

The result display basis of the step (5) is as follows:

the concentration values of the cytokine markers are determined according to the following criteria for severe and non-severe cases:

furthermore, the system can also comprise a communication equipment association device or an interface, wherein the communication equipment association device or the interface is used for connecting a computer, a mobile phone, a storage cloud end or other mobile equipment;

the data collection module can also be connected with a noninvasive medical detection device, and the noninvasive medical detection device comprises a cytokine concentration tester.

The above embodiments are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents thereof, and all such changes, modifications, substitutions, combinations, and simplifications are intended to be included in the scope of the present invention.
