Objective: To measure serum testosterone level, plasma levels of interleukin-18 (IL-18) and IL-10 and explore their correlation in patients with different types of coronary heart disease (CHD), and their possible role in occurrence and development of CHD. Methods: A total of 96 male CHD patients were divided into acute myocardial infarction (AMI) group (n=35), unstable angina pectoris (UAP) group (n=32) and stable angina pectoris (SAP) group (n=29). Another 30 patients who were excluded for CHD by coronary angiography were enrolled as non CHD control group. Enzyme linked immunosorbent assay (ELISA) was used to measure serum testosterone level and plasma levels of IL-18 and IL-10 in all groups. Results: Compared with non CHD control group, there were significant decreases in serum testosterone level [(13.46±1.99) mmol/L vs. (6.89±1.35) mmol/L vs. (5.02±1.87) mmol/L, t=1.917～2.365, P<0.05 both] in UAP group and AMI group, and that of AMI group was significantly lower than that of UAP group, t=1.034, P<0.05; there were significant increases in IL-18 levels [(146.72±79.36) pg/ml vs. (209.32±80.49) pg/ml vs. (316.78±75.63) pg/ml vs. (457.78±83.21) pg/ml, t=2.016～3.167,P<0.05 all] in SAP group, UAP group and AMI group, and those of UAP group and AMI group were significantly higher than that of SAP group, t=2.173, 2.596, P<0.05; there were significant increases in IL-10 levels [(48.46±18.27) pg/ml vs. (116.45±42.76) pg/ml vs. (85.64±27.33) pg/ml vs. (70.26±18.55) pg/ml, t=2.997～2.018, P<0.05 all] in SAP group, UAP group and AMI group, and those of AMI group and UAP group were significantly lower than that of SAP group (t=2.034, 2.291, P<0.05 both). Pearson linear regression analysis indicated that serum testosterone level was negatively correlated with levels of IL-10 (r=-0.678, P<0.01) and IL-18 (r=-0.579, P<0.01) in CHD group. Conclusion: There are significant changes in serum testosterone level and plasma IL-18, IL-10 levels, and testosterone level is significantly negatively related with IL-18, IL-10 levels, and they can be regard as new indexes assessing coronary atherosclerotic lesion.

Objective:To evaluate the effectiveness of correction of sunken upper eyelid with central orbital fat transposition during upper blepharoplasty.Methods:We performed 58 cases of upper blepharoplasty with sunken upper eyelids during January 2016 and June 2020. The lateral portion of the central orbital fat was dissected and reversed 180 degrees, and then fixed to the medial fat pad. Photographs before and 6 months post-operatively were measured to determine the degree of the upper eyelid depression. The results were compared statistically. At the consultation 6 months postoperatively, the patients were asked to evaluate the results of the operation using the Clients Satisfying Questionnaire, with the grade between 4 (very satisfactory) and 0 (very dissatisfactory).Results:Sunken eyelids were effectively corrected in 41 of the 52 patients, but 11 patients had minimal effect because of the lack of sufficient central fat volume mostly due to the prior blepharoplasty. At 6 months post-operatively, 52 of the 58 patients finished the satisfaction questionnaire. Forty one of the 52 patients were satisfying with the results. The mean score was 3.3+ 0.73. The degree of the upper eyelid depression was (4.9+ 1.1) mm preoperatively and (2.4+ 0.7) mm postoperatively. There was a statistically significant difference ( P<0.05). Conclusions:The central orbital fat transposition is an effective way to correct the sunken upper eyelids during the upper blepharoplasty. The results are satisfactory with full upper eyelids and smooth double eyelids.

Sunlight consists of lights of continuous spectra. Ultraviolet light and blue light in the sunlight have higher energy. High dose exposure to sunlight can cause direct cellular damage. In the eye, sunlight is known to cause pathological changes in various eye structures. We reviewed the studies on the role of sunlight in corneal diseases, cataracts, glaucoma, and age-related macular degeneration in recent years. Possible sunlight-triggered signaling pathways and mechanisms in the eye are summarized. Excessive exposure to sunlight may lead to increased DNA damage, aberrant protein modification and aggregation, and oxidative stress of ocular tissues, and thus results in the development of ocular diseases. Accordingly, physical protection, topical and/or oral antioxidants and small molecules blocking sunlight-activated signal pathways could be used independently or combinedly to prevent and reduce sunlight-induced ocular damages.

ObjectiveTo explore the underlying mechanism of bran-fried Atractylodis Rhizoma （AR） in improving gastrointestinal function by comparing the effects of raw AR and bran-fried AR on the small intestine tissue structure and transport-related protein carriers in rats with spleen deficiency syndrome. MethodSeventy male SD rats were randomly divided into a normal group， a model group， high- and low-dose raw AR groups （10， 2.5 g·kg^-1）， high- and low-dose bran-fried AR groups （10， 2.5 g·kg^-1）， and a compound glutamine group （9 mg·kg^-1）， with 10 rats in each group. Except for the normal group， the other six groups were subjected to the spleen deficiency model induced by the method of bitter and cold breaking stagnated Qi and abnormal hunger and fullness for 21 days. After modeling， each treatment group was given medication orally according to the corresponding doses every day for a total of 14 days， and the normal group and the model group were given an equal volume of normal saline orally. During the treatment period， the general survival status， macroscopic syndrome score， daily increase in body weight and food intake， and rectal temperature of the spleen deficiency rats were evaluated， and after the treatment， the rats were sacrificed. The pathological changes in the small intestine tissues of each group were observed by hematoxylin-eosin （HE） staining. The content of serum 5-hydroxytryptamine （5-HT） was detected by enzyme-linked immunosorbent assay （ELISA）， and the content of serum D-xylose， lactate， and amylase was detected by colorimetry. The levels of free fatty acid receptor 3 （FFA3） and peptide transporter 1 （PepT1） in small intestinal tissues were detected by the Bradford method， and the protein expression of sodium-dependent glucose transporter 1 （SGLT1） and glucose transporter 1 （GLUT1） in small intestinal tissue was detected by immunohistochemistry. Real-time fluorescence-based quantitative PCR was used to detect the mRNA expression of glucose transporter 2 （GLUT2）， sodium/hydrogen exchanger 3 （NHE3）， and 5-hydroxytryptamine receptor 4 （5-HT4R）. ResultCompared with the normal group， the model group exhibited symptoms of spleen deficiency， such as sluggishness， squint， reduced food intake， and lethargy at the end of modelling， damaged basic structure of the small intestinal mucosal epithelium and lamina propria， increased serum lactate and 5-HT content， and decreased serum amylase and D-xylose （P<0.01）. Compared with the model group， all treatment groups showed varying degrees of improvement， with the small intestinal microstructure repaired to different degrees. The daily weight gain， anal temperature， and macroscopic syndrome score of spleen deficiency improved to varying degrees （P<0.05， P<0.01）. The serum lactate and 5-HT content decreased to varying degrees， while the serum amylase and D-xylose content increased to varying degrees （P<0.05， P<0.01）. The PepT1 content in the small intestinal tissues increased， while the FFA3 content decreased to varying degrees. The protein expression of SGLT1 and GLUT1 increased， while the mRNA expression of GLUT2 and NHE3 increased to varying degrees. The mRNA expression of 5-HT4R decreased to varying degrees （P<0.05， P<0.01）. Compared with the high- and low-dose raw AR groups， the high- and low-dose bran-fried AR groups showed significant improvement in general conditions and histopathological improvement of the small intestinal tissues. The daily weight gain， anal temperature， and macroscopic syndrome score of spleen deficiency also improved （P<0.05， P<0.01）. The serum lactate and 5-HT content decreased， while the serum amylase and D-xylose content increased （P<0.05， P<0.01）. The PepT1 content in the small intestinal tissues increased， while the FFA3 content decreased. The protein expression of SGLT1 and GLUT1 increased， while the mRNA expression of GLUT2 and NHE3 increased. The mRNA expression of 5-HT4R decreased significantly （P<0.05， P<0.01）. ConclusionBran-fried AR can improve the spleen deficiency-related symptoms and histopathology of the small intestinal tissues in spleen deficiency model rats. Its mechanism may be related to the regulation of the expression of various transport-related protein carriers and the secretion of various digestive enzymes after stir-frying of AR， thus restoring the absorption and transport function of the small intestine.

Objective:To understand the current situation of nurses in 52 hospitals in China on mastery of knowledge about skin injury in the elderly based on the background of mixed-mode homogenization training.Methods:Using the convenient sampling method, a total of 1 067 nurses from 52 hospitals in China were selected as the research objects in January 2021. A self-designed questionnaire on knowledge of skin injury in the elderly was used to investigate the nurses through the questionnaire star and univariate analysis was used to analyze the influencing factors. A total of 1 067 questionnaires were distributed and 1 067 valid questionnaires were recovered, and the effective recovery rate was 100%.Results:The knowledge scores of pressure injury, incontinence-associated dermatitis, skin tear and xerosis cutis among 1067 nurses were (95.66±7.37) , (95.65±9.15) , (91.37±15.45) and (87.67±15.91) , respectively. The results of univariate analysis showed that hospital grade was the influencing factor of nurses' knowledge score of pressure injury, skin tear and incontinence-associated dermatitis ( P<0.05) , educational background was the influencing factor of nurses' knowledge score of skin tear ( P<0.05) , professional title was the influencing factor of nurses' knowledge scores of pressure injury, incontinence-associated dermatitis and xerosis cutis ( P<0.05) . Conclusions:Hospitals at all levels need to strengthen the theoretical and practical knowledge training for nurses on skin xerosis and skin tear in the elderly, especially for nurses with primary titles and lower education in grassroots hospitals.

AIM: The main chemical components of Yufang Fangji II (Hubei Fang) of COVID-19 were studied systematically and combined with network pharmacology to provide a reference for the study of its effective substances. METHODS: Ultra high-performance liquid chromatography quadrupole time of flight mass spectrometry (UHPLC-Q-TOF/MS) was applied to identify the absorbed components of the prescription in rat plasma. TCMSP database and Swiss Target Prediction data platform were used to predict the target of the identified blood components, and network visualization software Cytoscape 3.7.2 was used draw the association network diagram, and GO enrichment analysis and KEGG pathway enrichment analysis were conducted for the key targets. With the help of CB-Dock online molecular docking platform, the molecular docking of key targets and blood entering compounds was carried out, and the docking combination with good affinity value was displayed by ligplot software to verify the preventive effect of Yufang Fangji II on COVID-19. RESULTS: A total of 52 chemical components identified in the prescription, in which 13 components were absorbed in the rat plasma as the prototype, and they were from Astragalus membranaceus, Atractylodes macrocephala, Saposhnikoviae Radix, Lonicerae Japonicae Flos, and Citri Reticulatae Pericarpium, respectively. These compounds were recognized to act on 17 core targets, including mapk3, TNF and other targets related to inflammation, MPO and other targets related to oxidative stress, VEGFR, KDR and other targets related to vascular endothelium. The results of molecular docking showed that the absorbed components had good binding activity with the key targets. CONCLUSION: Compounds in Yufang Fangji II are involved in regulating inflammation, oxidative stress, vascular and cellular physiological activities, which have preventive effects on COVID-19 through regulating IL-17, PI3K Akt, MAPK and other pathways.
