Objective To investigate the early predictive value of combined detection of serum sodium,heparin-binding protein-to-albumin ratio(HBP/ALB)and interleukin-10(IL-10)in Ka-wasaki disease shock syndrome(KDSS)caused by Kawasaki disease in children.Methods A total of 105 children with KDSS caused by Kawasaki disease(KDSS group)and 105 children with Kawasa-ki disease(control group)were selected as study subjects.Clinical data,serum sodium levels,HBP/ALB and IL-10 levels were compared between the two groups.Multivariate logistic regression a-nalysis was used to screen the influencing factors of KDSS caused by Kawasaki disease in children a-mong serum sodium,HBP/ALB and IL-10.Receiver operating characteristic(ROC)curve analysis was conducted to evaluate the predictive value of traditional prediction schemes(coronary artery dam-age and IVIG resistance)and new prediction schemes(serum sodium and HBP/ALB,IL-10)for KDSS caused by Kawasaki disease in children.Results The proportion of patients with coronary ar-tery damage and IVIG resistance was significantly higher in the KDSS group than those in the control group(P＜0.05).Serum sodium levels were lower,while HBP/ALB and IL-10 levels were higher in the KDSS group compared to the control group(P＜0.05).Multivariate logistic regression analysis showed that serum sodium,BP/ALB and IL-10 were influencing factors of KDSS caused by Kawasaki diseasein children(P＜0.05).For traditional prediction schemes,the areas under the curves(AUCs)for coronary artery damage,IVIG resistance and their combination in predicting KDSS caused by Kawasaki disease were 0.795,0.676 and 0.873,respectively(P＜0.05);for new prediction schemes,the AUCs for serum sodium,HBP/ALB,IL-10 and their combination in predicting KDSS were 0.767,0.824,0.760 and 0.945,respectively(P＜0.05).The AUC for the combination of serum sodium,HBP/ALB and IL-10 was greater than that for the combination of coronary artery dam-age and IVIG resistance(P＜0.05).Conclusion Decreased serum sodium,elevated HBP/ALB and elevated IL-10 are associated with KDSS caused by Kawasaki disease in children.Combined prediction using serum sodium,HBP/ALB and IL-10 has a high predictive value for KDSS caused by Kawasaki disease in children.

Chronic disease patients often experience negative emotions such as anxiety and depression,and the accurate assessment of these emotions is crucial for developing effective care plans and interventions.Traditional assessments of negative emotions are limited by subjectivity,error and accessibility issues,making precise identification and evaluation difficult.In recent years,vision technology has demonstrated unique advantages in emotion recognition due to its accuracy,speed,consistency,objectivity nature.This paper reviews the development process of computer vision technology,the content and effects of its application in negative emotion assessment for chronic disease patients,and the current challenges,in order to provide references for the evaluation of chronic disease patients'negative emotions.

Objective:To explore the effect of early essential newborn care technology during cesarean section on early health outcomes of mothers and infants and breast feeding.Methods:This study was a randomized controlled study. From October 2020 to August 2021, 104 delivery women and their newborns who were scheduled for full-term cesarean section in Peking University First Hospital were selected as the study subject. The subjects were randomly divided into control group and intervention group, 52 cases in each group. The control group received routine nursing of the newborn after cesarean section, while the intervention group received early essential newborn care technology after cesarean section. The amount of postpartum hemorrhage, hospital stay, Apgar score at one and five minutes after birth, the incidence of abnormal conditions within 90 minutes after birth, the time of umbilical cord shedding, the time of the first feeding sign of the newborn, the success rate of early initiation of breastfeeding and the implementation of breast feeding at discharge were compared between the two groups.Results:There was no statistical difference between the two groups in the amount of postpartum hemorrhage within two hours, the amount of postpartum hemorrhage within two to 24 hours and the number of days in hospital ( P>0.05) . There was no statistical difference between the two groups in Apgar scores at one and five min after birth ( P>0.05) . There was no statistical difference between the two groups in the occurrence of re-attraction, respiratory abnormalities, resuscitation, Neonatal Intensive Care Unit (NICU) transfer and other abnormalities within 90 minutes after birth ( P>0.05) . There was no statistical difference in the time of umbilical cord shedding between the two groups ( P>0.05) , and no umbilical infection occurred. The first foraging reflex in the intervention group was earlier than that in the control group, and the success rate of early initiation of breastfeeding was higher than that in the control group, and the differences was statistically significant ( P<0.05) . There was no statistical difference in the implementation of breast feeding between the two groups at discharge ( P>0.05) . Conclusions:It is safe and feasible to implement early essential newborn care technology during cesarean section, and it can effectively promote early initiation of breastfeeding, which is of great significance for breast feeding and has the value of clinical promotion.

Objective:To assess the value of the parotid fat fraction (FF) and T 2 relaxation time (T 2 value) in the evaluation of early parotid involvment in patients with primary Sj?gren′s syndrome (pSS) using multi-echo Dixon technique and T 2 mapping imaging. Methods:From December 2018 to December 2019, 26 early pSS patients (pSS group) and 20 healthy controls (control group), matched to age and gender, were enrolled at the First Affiliated Hospital of Zhengzhou University in this prospectively study. All subjects underwent conventional MRI, DWI, multi-echo Dixon and T 2 mapping sequences before treatment. The ADC, FF and T 2 value of bilateral parotid parenchyma in pSS group and control group were measured respectively. Paired sample t test was used to compare the differences of ADC, FF and T 2 values between left and right parotid glands for pSS group and control group, while independent sample t test was used to compare the differences of ADC, FF and T 2 values between pSS group and control group. The ROC curves were drawn to evaluate diagnostic performance of ADC, FF and T 2 values to distinguish early pSS, and the difference of diagnostic efficacy of each parameter was compared by Delong test. Binary logistic regression analysis and ROC curve were used to evaluate the diagnostic performance of the combination of the 3 parameters in early pSS. Results:There were no significant differences of ADC, FF and T 2 values between left and right parotid glands for pSS group and control group (all P>0.05). The parotid ADC values were significantly lower in pSS group than control group ( t=4.641, P=0.006), while the FF and T 2 values of pSS group were significantly higher than those of control group ( t=-2.910, -6.411, both P<0.001). The areas under the ROC curve of ADC, FF and T 2 values to distinguish early pSS were 0.666, 0.750 and 0.862, respectively. The area under ROC curve of the combination of ADC, FF and T 2 values was 0.930, with a sensitivity of 73.1% and a specificity of 97.5%. T 2 values showed a better diagnostic efficacy than ADC values ( Z=2.626, P=0.009) and FF values ( Z=2.112, P=0.035) when distinguishing pSS group from control group. The area under ROC curve of the combination of ADC, FF and T 2 values showed a better diagnostic efficacy than each parameter alone ( Z=4.869, P<0.001, Z=3.628, P<0.001, Z=2.162, P=0.031). Conclusions:Multi-echo Dixon technique and T 2 mapping can quantitatively evaluate the parotid gland fat deposition and inflammatory response in the early stage of pSS. T 2 value has great potential in evaluating early parotid gland injury of pSS, and the combination of ADC, FF and T 2 values can further improve the diagnostic efficiency.

Objective To introduce the development strategy of“Internet Plus”AIDS prevention services and its implementation results from 2010 to 2015 in Guangzhou, China. Methods A gay men's health column was created for an active website aimed at men who have sex with men (MSM), in collaboration with local community organizations and the Guangzhou CDC. We designed intervention tools (including scenario-based applications and HIV risk self-assessment systems) and an online HIV testing service platform, integrated with applied psychology and behavioral theory as well as the“Internet Plus”concept, to intervene in HIV infection risk factors among MSM. Data of clients who accessed the“Internet Plus”AIDS services from 2010 to 2015 were used to evaluate service operation. Six-year consecutive surveys, conducted between April and July of each service year, were collected using a national AIDS sentinel surveillance questionnaire. For each year of surveillance, information on HIV prevalence, HIV interventions received during the past year, unprotected anal intercourse in the past 6 months, and HIV testing in the past year were compared using the chi-squared (χ2) test, to roughly reflect the effect of“Internet Plus”AIDS prevention services. Results As of 31 December 2015, a total of 34 395 MSM had received“Internet Plus”services and HIV testing. The number of MSM tested increased from 2 338 in 2010 to 8 054 in 2015. From 2010 to 2015, newly identified HIV cases in each year were 59, 166, 312, 283, 291, and 270, which accounted for 25.0%, 32.8%, 38.8%, 35.1%, 30.5%, and 23.2% of MSM HIV cases of Guangzhou, respectively. Sentinel surveillance data showed that during the study period, 3 047 MSM were investigated, with 405, 400, 401, 633, 608, and 600 each year, respectively. The proportion of participants who had received any HIV intervention during the past year was 74.3% (301), 70.8% (283), 83.3% (334), 85.0%(538), 69.1%(420), and 83.8%(503) each year, respectively (trend χ2=6.53, P=0.011). HIV testing done during the past year accounted for 44.0%(178), 44.3%(177), 49.4%(198), 53.4%(338), 56.1%(341), and 60.2%(361) each year, respectively (trendχ2=40.83, P<0.001). Unprotected anal intercourse in the past 6 months accounted for 59.3% (240), 62.0% (248), 56.6% (227), 57.0% (361), 48.4% (294), and 43.7%(262) each year, respectively (trend χ2=42.21, P<0.001). Conclusion The“Internet Plus”AIDS prevention services in this study represent a manner to enhance traditional HIV prevention strategies. We found these services to be effective in implementation of the national AIDS control and prevention strategy, especially for the expansion of intervention, testing, and case identification among high-risk populations.

The purpose of this study is to investigate the penetration effects and mechanism of N-arginine chitosan (ACS). This novel transdermal enhancer with a mimetic structure of cell-penetration peptides was synthesized by introducing hydrophilic arginine groups to the amino-group on chitosan's side chain. The structure of ACS was confirmed by FT-IR, 1H NMR and element analysis. In addition, attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) was used to study the protein conformation and the water content of stratum corneum, and the result suggested that ACS can change the orderly arrangement of the molecules in the stratum corneum, making the stack structure of keratin become loose. And ACS can increase the water content of the stratum corneurn. Inverted fluorescence microscope and flow cytometry were used to examine penetration effect of ACS on Hacat cell. The result confirmed that the uptake of ACS was enhanced with increased substitution degree of arginine by 4-8 folds compared to chitosan. In vitro penetration studies on three electrical types of drugs were carried out using three model drugs of negatively charged aspirin, positively charged terazosin and neutral drug isosorbide mononitrate by the method of Franz diffusion cells. The results showed that ACS has obviously penetration of the negatively charged drug aspirin, and certain penetration of neutral drug issorbide mononitrate, but inhibition of positively charged terazosin. In vivo imaging technology research results show that the ACS can significantly enhance the fluorescence intensity of morin, which is the auto-fluorescence anionic drug. These obtained results suggested that ACS, as a promising transdermal enhancer, can change the structure of the keratinocytes and analog penetrating peptides promote absorption, but have certain selectivity for the drug.

Objective To investigate the expression of Dysadherin and analyze its role in renal clear cell carcinoma (RCCC).Methods RT-PCR and immunohistochemical were used to detect the expression of Dysadherin in 60 cases of fresh RCCC and 60 adjacent normal renal tissues(male 35,female 25; age 37-78,median age 61; ＞7 cm 24,≤7 cm 36; Ⅰ/Ⅱ 39,Ⅲ/Ⅳ 21).Results Dysadherin mRNA expression in RCCC tissues (2.0043±0.2890) was higher than that in adjacent normal renal tissues (0.8461 ±0.2479) (t =6.8020,P ＜ 0.05).Dysadherin expression was associated with nuclear grade.The expression of Dysadherin in nucleus grade Ⅲ and Ⅳ tumors were significantly higher than that in nucleus grade Ⅰ and Ⅱ tumors [the mRNA expression were 4.6224±0.3194,2.7780±0.2288,the positive rates of protein were 64.1％ (25/39),95.2 ％ (20/21) (t =6.5750,x2 =5.495,P ＜ 0.05)].There was no association between the expression of Dysadherin with sex (t =1.0530,x2 =0.023),age(t =0.0511,x2 =0.089) and tumor size (t =1.0330,x2 =0.370) (P ＞ 0.05).Conclusion In RCCC,Dysadherin expression is positively associated with tumor aggressiveness based on grading.It seems that Dysadherin may be a valuable prognostic marker in RCCC.
