Sjogren's syndrome (SS) is a common autoimmune disorder that primarily targets exocrine glands, leading to hallmark manifestations of xerostomia and xerophthalmia, with potential progression to multisystem involvement. The rapid advances in omics technologies-including metabolomics, proteomics, and transcriptomics-have yielded substantial insights into SS pathophysiology. This review consolidates current evidence on omics-derived biomarkers in SS. Studies consistently implicate aberrant glucose metabolism, neutrophil-derived enzyme activity, mitochondrial bioenergetic impairment, ferroptosis, and apoptotic pathways as central to SS development. These findings refine our understanding of disease mechanisms and the heterogeneity of therapeutic responses. Hydroxyproline has emerged as a candidate marker for distinguishing SS from IgG4-related disease, whereas distinct cytokine and chemokine signatures may enable earlier diagnosis. Genomic analyses demonstrate a robust association between expression of the rs11797 locus and SS-related lymphomagenesis, and several genes controlling DNA methylation represent promising therapeutic targets. Collectively, these findings lay the groundwork for personalized risk stratification and intervention in SS. The review concludes by summarizing existing progress and outlining priorities for future omics-based investigations.

AIM:To investigate the molecular mechanism of long noncoding RNA(lncRNA)SNHG1 in regu-lating ferroptosis to alleviate inflammation in CHME-5 human microglia induced by HIV-1 gp120 V3 loop.METHODS:CHME-5 human microglia were cultured in vitro,and were divided into 7 groups:blank group,random peptide group,gp120 V3 loop group(HIV-1 gp120 group),HIV-1 gp120+shCon group,HIV-1 gp120+SNHG1 sh2 group,HIV-1 gp120+SNHG1 sh2+ferrostatin-1(Fer-1;ferroptosis inhibitor)group,and HIV-1 gp120+SNHG1 sh2+EX527(Sirt1 in-hibitor)group.Normal CHME-5 cells were treated with random peptide or gp120 V3 loop for 24 h.After pretreatment of SNHG1 sh2 cells with inhibitors for 2 h,the cells were then treated with gp120 V3 loop for 24 h.The levels of inflammato-ry cytokines in the cell supernatants were detected by ELISA.Western blot was used to detect the protein expression levels of solute carrier family 7 member 11(SLC7A11),glutathione peroxidase 4(GPX4),Sirt1 and p53.Microplate reader was used to detect the levels of intracellular ferrous ion(Fe2+)and malondialdehyde(MDA).RESULTS:(1)The results of ELISA showed that the expression levels of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and IL-1β in HIV-1 gp120 group were significantly higher than those in blank group(P<0.05).Compared with HIV-1 gp120 group,the ex-pression levels of inflammatory cytokines in HIV-1 gp120+SNHG1 sh2 group were significantly decreased(P<0.05).Compared with HIV-1 gp120+SNHG1 sh2 group,the expression levels of inflammatory factors in HIV-1 gp120+SNHG1 sh2+Fer-1 were significantly decreased(P<0.05),but those in HIV-1 gp120+SNHG1 sh2+EX527 group were significant-ly increased(P<0.01).(2)The results of Western blot showed that compared with blank group,the expression levels of ferroptosis-related proteins SLC7A11 and GPX4 in HIV-1 gp120 group were significantly down-regulated(P<0.01).Com-pared with HIV-1 gp120 group,the expression levels of SLC7A11 and GPX4 in HIV-1 gp120+SNHG1 sh2 group were sig-nificantly up-regulated(P<0.01).Compared with HIV-1 gp120+SNHG1 sh2 group,the expression levels of SLC7A11 and GPX4 in HIV-1 gp120+SNHG1 sh2+Fer-1 group were significantly up-regulated(P<0.05),but the expression levels of SLC7A11 and GPX4 in HIV-1 gp120+SNHG1 sh2+EX527 group were significantly down-regulated(P<0.01),and the expression level of p53 was significantly up-regulated(P<0.05).(3)Compared with blank group,the levels of Fe2+and MDA in HIV-1 gp120 group were significantly increased(P<0.05).Compared with HIV-1 gp120 group,the levels of Fe2+and MDA in HIV-1 gp120+SNHG1 sh2 group were significantly decreased(P<0.01).Compared with HIV-1 gp120+SNHG1 sh2 group,Fe2+and MDA in HIV-1 gp120+SNHG1 sh2+Fer-1 group were significantly decreased(P<0.05),but those in HIV-1 gp120+SNHG1 sh2+EX527 group was significantly increased(P<0.05).CONCLUSION:Knockdown of SNHG1 can attenuate the inflammation in microglia induced by HIV-1 gp120 V3 loop,which may be achieved by regulating ferrop-tosis-related signaling molecules through the Sirt1/p53 signaling pathway.

Objective To observe the value of 18F-FDG PET/CT semi-quantitative parameters for predicting spread through air spaces(STAS)of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.Methods Data of 85 patients with clinical stage Ⅰa—Ⅲ a lung adenocarcinoma who underwent preoperative 18F-FDG PET/CT were retrospectively analyzed.The patients were divided into positive group(n=23)or negative group(n=62)according to whether pathology showed STAS or not.Clinical and PET/CT data were compared between groups,and logistic analysis was performed to explore the efficacy of each parameter for predicting STAS.Results Significant differences of gender,carcinoma embryonic antigen,clinical stage,pathological grade,micropapillary growth and proportion were found between groups(all P＜0.05).The maximum,the mean,the peak standard uptake value(SUVmax,SUVmean,SUVpeak),as well as the maximum,the mean and the peak standard uptake value normalized by lean body mass(SULmax,SULmean,SULpeak),also the total lesion glycolysis(TLG)in positive group were all significantly higher than those in negative group(all P＜0.05).Patients'gender,proportion of micropapillary growth,SUVmax and SULmax were all independent risk factors of STAS of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.The area under the curve(AUC)of the above parameters for predicting STAS was 0.666,0.912,0.839 and 0.842,respectively,and of the combination was 0.957.Conclusion 18 F-FDG PET/CT semi-quantitative parameters SUVmax and SULmax were helpful for predicting STAS of clinical stage Ⅰa—Ⅲ a lung adenocarcinoma,and further combination of gender and proportion of micropapillary growth could improve diagnostic efficacy.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

Objective:To explore the application effect of defect scenario simulation combined with joint review action in the training of blood-borne occupational exposure of nursing assistants.Methods:From February 1, 2020 to February 1, 2021, a total of 97 nursing assistants from Central District of Provincial Hospital Affiliated to Shandong First Medical University, were selected as the experimental group and 89 nursing assistants from the Eastern District were selected as the control group. The control group received routine training, while the observation group received defect scenario simulation combined with action training. After 1 year of training, the incidence of blood-borne occupational exposure and blood-borne occupational exposure knowledge scores of nursing assistants in the two groups were compared.Results:During the intervention period, 1 nursing assistant in the experimental group resigned, 2 nursing assistants asked for leave twice or more, and 94 nursing assistants were finally enrolled. In the control group, 2 nursing assistants resigned and 3 nursing assistants asked for leave twice or more, and 84 nursing assistants were eventually enrolled. The incidence of blood-borne occupational exposure of nursing assistants in the experimental group was lower than that in the control group and the score of blood-borne occupational exposure knowledge was higher than that in the control group, and the differences were all statistically significant ( P<0.05) . Conclusions:Defect scenario simulation combined with joint review action has a good effect in blood-borne occupational exposure training of nursing assistants, which can reduce the incidence of blood-borne occupational exposure and improve their blood-borne occupational exposure knowledge scores. It is worthy of clinical promotion.

Objective To explore the hospitalization time and family financial burden of children under 14 years old with severe asthma in this region. Methods Children under 14 years old with severe asthma who were admitted to our hospital from January 2017 to December 2019 as a result of an acute attack were selected in this study. Questionnaire surveys, hospital charging system, and follow-up methods were used to collect clinical data, length of hospital stay, and direct and indirect costs of the children with asthma. Stepwise regression was applied to analyze the factors influencing the total cost. Results A total of 206 children were enrolled from 2017 to 2019, including 117 males and 89 females, with an average age of (7.24±1.53) years old. The total age distribution mainly consisted of six months to 3 years old (33.01%), >3 to 4 years old (24.27%), and >6-13 years old (20.39%). The onset season was mainly autumn and winter (33.01%). The average length of hospital stay was (8.50±1.42) d. The annual average family cost was (6884.20±957.61) RMB. The length of hospital stay decreased year by year, while the total cost increased year by year (P<0.05). Multiple stepwise regression analysis showed that the length of hospitalization, antibiotic use time, and presence/absence of allergic rhinitis, pulmonary heart disease and GINA standard treatment were the related factors affecting the total cost in children with severe asthma (P<0.05). Conclusion From 2017 to 2019, the hospitalization time of children under 14 years old with severe asthma in this region decreased over time, while the total cost gradually increased. Shortening the hospitalization time, actively preventing and controlling complications, and standardizing treatment can effectively reduce the financial burden of children's families.

Solid tumors always exhibit local hypoxia, resulting in the high metastasis and inertness to chemotherapy. Reconstruction of hypoxic tumor microenvironment (TME) is considered a potential therapy compared to directly killing tumor cells. However, the insufficient oxygen delivery to deep tumor and the confronting "Warburg effect" compromise the efficacy of hypoxia alleviation. Herein, we construct a cascade enzyme-powered nanomotor (NM-si), which can simultaneously provide sufficient oxygen in deep tumor and inhibit the aerobic glycolysis to potentiate anti-metastasis in chemotherapy. Catalase (Cat) and glucose oxidase (GOx) are co-adsorbed on our previously reported CAuNCs@HA to form self-propelled nanomotor (NM), with hexokinase-2 (HK-2) siRNA further condensed (NM-si). The persistent production of oxygen bubbles from the cascade enzymatic reaction propels NM-si to move forward autonomously and in a controllable direction along H

Objective: To investigate the echocardiographic characteristics, pathological anatomy and genetic abnormality of congenital absent semilunar valves in first trimester. Methods: Eleven cases of congenital absent semilunar valve fetus diagnosed at 11-13^{+ 6} weeks of gestation in Guangxi Magernity & Child Healthcare Hospital from December 2014 to December 2018 were analyzed. The characteristics of echocardiography and the abnormal microanatomy of cardiac tissue after labor induction was compared. Results: The crown-lump length of the 11 fetus was 46-74(62.0±9.2)mm, and nuchal translucency thickness(NT) was 2.4-10.4 (6.4±2.6)mm. The NT of 10 cases were greater than 3.0 mm. Color Doppler flow imaging revealed that biphasic bidirectional flow in the aortic arch and/or pulmonary artery at the 3VT view( "to-and-fro" ) in those 11 cases, and pansystolic turbulence and pandiastolic reflux spectrum were showed on spectral Doppler. Among them, there were 10 cases of " stealing type" , including 2 cases of isolate absent aortic valves, 3 cases of absent pulmonary valves and 5 cases of absent both aortic and pulmonary valves; and all the 10 cases had secondary ultrasonic manifestations of fetal heart failure. Chromosome analysis and detection of genes showed that 4 cases with Trisomy 13 syndrome, 3 cases with Trisomy 18 syndrome, 1 case with 22q11.2 deletion, 1 case with 12q24.32q24.33 deletion and 1 case was normal. Pathological anatomy revealed enlarged heart in 8 cases, isolate absent aortic valves in 2 cases (1 case complicated with pulmonary atresia, absence of ductus arteriosus and thymus), absent pulmonary valves in 3 cases, absent both aortic and pulmonary valves in 3 cases, relics of semilunar valves in 3 cases. And 2 cases of absent pulmonary valves and 3 cases of absent both aortic and pulmonary valves with short and thick ductus arteriosus. Only 1 case was congenital absent semilunar valve in " non-stealing type" without secondary ultrasonic manifestations of fetal heart failure. Chromosome analysis and detection of genes showed 22q11.2 deletion, and there were relics of semilunar valves in the pathological anatomy. It also combined with tetralogy of Fallot and absence of ductus arteriosus. Conclusions In first trimester, congenital absent semilunar valves are more common as " stealing type" . The echocardiographic features of congenital absent semilunar valves are the " in-out sign" of aorta arch and/or pulmonary artery and biphasic spectrum in spectral Doppler. Trisomy 13 syndrome and trisomy 18 syndrome significantly increased the risk of congenital absent semilunar valves in " stealing type" in first trimester.

The scar contracture of Achilles tendon in burn patients after operation is easy to cause " foot drop" , which leads to ankle dorsiflexion dysfunction. To solve this problem, the authors designed and made a static progressive ankle foot orthosis. The foot support part and the crus support part of the orthotic device are connected by rivets, and the distal end of the foot support part and the proximal end of the crus support part are pulled by the traction belt on both sides, gradually improving the ankle dorsiflexion function. This static progressive ankle foot orthosis is simple, practical, cost-effective, and worthy of clinical promotion.
