Renal tumor scoring systems can describe the anatomical characteristics of renal tumors. It is an important standard to evaluate the surgical complexity and to evaluate the surgical complexity and feasibility of partial nephrectomy. Scholars at home and abroad have established various scoring systems based on different anatomical parameters，such as R.E.N.A.L.，PADUA，C-Index，which are used to guide the clinical selection of surgical modalities，and predict perioperative complications and prognosis. In this paper，various scoring systems are grouped into three major categories according to their functions：prediction of surgical complexity，prediction of complications，and prediction of prognosis. The contents，characteristics and clinical application value of various renal tumor scoring systems are introduced in detail to guide urologists，enhance their surgical decision-making ability，and improve the clinical outcomes.

Medicinal plants have provided numerous medicinal active ingredients for thousands of years and these ingredients have been used in Chinese medicine (CM) and traditional pharmacologies worldwide. Recently, the exploitation and utilisation of medicinal plant resources has increased significantly. The results of the studies have led to the identification of many active components, such as steroidal alkaloids, saponins, terpenoids, and glycosides, in various medicinal plants with different evolutionary levels. Moreover, research on the chemical classification, molecular phylogeny, and pharmacological activity of medicinal plants is increasing in popularity. Pharmacophylogeny is an interdisciplinary topic that studies the correlation between plant phylogeny, chemical composition, and curative effects (pharmacological activity and the traditional curative effect) of medicinal plants. In addition, it provides the basic tools to enable research and development of CM resources. This literature review, based on the genetic relationship between phytogroup and species, highlights the formation process, research content, applications, and future directions of pharmacophylogeny.

Abstract: Objective　To analyze the clinical characteristics and changes of serum IgG, IgM antibodies in patients infected with the SARS-CoV-2 B.1.1.529 (Omicron) variant. Methods　The clinical data of 82 patients with SARS-CoV-2 B.1.1.529 variant was analyzed retrospectively. Based on the presence of pneumonia on chest CT, the patients were divided into pneumonia group and non-pneumonia group. Serum IgG, IgM antibodies were observed at 5 time points T1 (1~<4 d), T2 (4~<8 d), T3 (8~<15 d), T4 (15~<22 d) and T5 (22~<30 d) after admission. Results　Among the 82 patients infected with the SARS-CoV-2 B.1.1.529 variant strain, there were 62 cases of cough, 31 cases of fever, 33 cases of throat discomfort, 5 cases of muscle soreness and 3 cases of diarrhea. The serum IgG antibody levels at 5 time points were 50.22 (142.20) AU/mL, 326.50 (220.63) AU/mL, 368.23 (76.21) AU/mL, 368.65 (79) AU/mL, and 385.26 (113.10) AU/mL, respectively. The level of serum IgG antibody in the pneumonia group was lower than that of the non-pneumonia group at T1 and T4 time points, and the differences were statistically significant (P<0.05) , the positive rate of serum IgG antibody in the pneumonia group was lower than that of the non-pneumonia group at the T1 time point, and the difference was statistically significant (P<0.05) . The serum IgM antibody levels at 5 time points were 0.41 (0.81) AU/mL, 0.95 (1.62) AU/mL, 1.09 (2.42) AU/mL, 0.74 (3) AU/mL, and 0.81 (3.10) AU/mL respectively, and there was no significant difference between the two groups. Conclusion　The clinical symptoms of patients infected with the SARS-CoV-2 B.1.1.529 variant strain are mild. Serum IgG antibodies increased after infection, but there are some differences between the pneumonia group and the non-pneumonia group, whether serum IgG has a protective effect needs further research; the serum IgM antibodies do not increase highly after infection, there are some differences between individuals.

OBJECTIVE: To establishment the Sense of Security Scale for Medical Staff and test its reliability and validity. METHODS: The pre-test version scale was formulated through methods of literature review, semi-structured interviews with clinical medical staff, discussion with members of research groups, and consultation with medical experts. A total of 350 and 403 medical staff who worked in a tertiary A hospital in Guangdong Province were selected as the prediction and the verification samples, respectively, by convenience sampling method. The reliability and validity of the final version scale were tested by item analysis, exploratory factor analysis and confirmatory factory analysis. RESULTS: Through item analysis, it was determined that the scale was mainly composed of 24 items. Exploratory factory analysis extracted five characteristics: environmental factors, patient factors, self factors, organizational management, and social support, that explained 72.8% of the total variation. The results of confirmatory factory analysis showed that the ratio of chi-square to degree of freedom was 2.851, the mean square error of approximation was 0.068, the standardized mean square residual was 0.078, the goodness of fit index was 0.883, the normative fit index was 0.904, the comparative fit index was 0.935, the non-standard fitting index was 0.924, and the incremental fitting index was 0.936. The results of reliability and validity test showed that the total Cronbach alpha coefficient, Spearman-Brown coefficient and retest reliability were 0.939, 0.967 and 0.808, respectively. The item reliability of each item was 0.420-0.814, the composite reliability was 0.775-0.920, the content validity ratio was 0.904, the convergent validity was 0.514-0.741, and the discriminative validity was 0.717-0.861. CONCLUSION: The reliability and validity of each dimension of the Sense of Security Scale for Medical Staff is good, and it can be used as an evaluation tool to measure the sense of security in medical staff.

Objective:To study the association between metabolic syndrome （MS） and Chinese healthy eating index （CHEI）， and to identify the beneficial or adverse effects of diets on MS in a community population of Shanghai. Methods:Based on the inclusion and exclusion criteria， the data of 4 856 subjects from a community in Shanghai was collected by interview. Total CHEI score and its component score were calculated based on the frequency of food consumption. Physical examination and blood biochemical tests were used to diagnose MS. The logistic regression model was used to analyze the relationship between MS or relative indexes and the total CHEI score or its component score. Results:The study showed the overall prevalence of MS was 24.71%. There were significant differences between MS group and controls （P<0.05） in age， BMI， waist circumference， fasting blood glucose， triglycerides， total cholesterol， systolic blood pressure， diastolic blood pressure， glycated hemoglobin， high-density lipoprotein and energy intake. After adjusting for potential confounders， it showed that the higher total CHEI score， the lower risk of central obesity， increased diastolic blood pressure， increased glycated hemoglobin， hyperglycemic and MS （P<0.05）. The increase in component score of potatoes， milk， beans， dark vegetables， fruits， oil and sodium reduced risk of obesity， hypertension， hyperglycemia， dyslipidemia and MS （P<0.05）. Conclusion:The quality of healthy diet （CHEI score more than 80） and increased intake of specific dietary components （potatoes， milk， beans， dark vegetables， fruits） reduce the risk of MS effectively.
