Objective:To explore the clinical characteristics of pregnancy complicated by primary Sj?gren's syndrome (pSS) and the related factors of adverse outcomes in pregnant women with pSS.Methods:A retrospective analysis was conducted on the clinical data of 32 pregnancies complicated by pSS treated in the Department of Obstetrics at the Third Affiliated Hospital of Guangzhou Medical University from February 2017 to August 2022. The patients were divided into two groups according to whether they had perinatal adverse outcomes: an adverse outcome group ( n=20) and a favorable outcome group ( n=12). The clinical characteristics of the two groups were compared with two independant sample t-test, Mann-Whitney U test, and Fisher's exact test, and multivariate logistic regression analysis was used to analyze the related factors of adverse outcomes in pregnant women with pSS. Results:(1) The average maternal age of the 32 pSS pregnancies was (32.9±4.6) years, the pre-pregnancy body mass index was (21.1±3.8) kg/m 2, and the median gestational age at delivery was 37.8 (35.4-38.5) weeks. There were 18 women (56.3%, 18/32) were diagnosed before pregnancy and 14 women (43.7%, 14/32) during pregnancy. Out of the 32 pregnancies, 25 (79.1%, 25/32) received therapy with glucocorticoids and/or hydroxychloroquine during pregnancy, whereas seven (21.9%, 7/32) had no medication during pregnancy. (2) The main adverse maternal outcomes included oligohydramnios (25%, 8/32), hypertensive disorder of pregnancy (18.8%, 6/32), preterm birth (18.8%, 6/32), fetal growth restriction (15.6%, 5/32), miscarriage (12.5%, 4/32), gestational diabetes mellitus (9.4%, 3/32), and postpartum hemorrhage (3.1%, 1/32). (3) Adverse neonatal outcomes included low birth weight infants in seven cases (25.0%, 7/28), neonatal asphyxia in seven cases (25.0%, 7/28), and two cases of congenital heart block (7.1%, 2/28). (4) The rate of diagnosis before pregnancy in the favorable outcome group was higher than the adverse outcome group [10/12 vs. 40.0%(8/20), Fisher's exact test, P=0.028]. There were no significant differences between the two groups concerning maternal age, pre-pregnancy BMI, weight gain during pregnancy, parity, rates of positivity for autoantibodies (antinuclear antibody, Sj?gren-specific antibody A, Sj?gren-specific antibody B, anti-Ro-52), and proportion of drug treatment (glucocorticoids, hydroxychloroquine) (all P>0.05). (5) Multivariate logistic regression analysis showed that diagnosis before pregnancy ( OR=0.02, 95% CI: 0.00-0.62, P=0.024) and positive Sj?gren-specific antibody B ( OR=0.01,95% CI: 0.00-0.75, P=0.038) were the protective factors. Conclusions:The clinical manifestations of pSS among pregnant women are varied and atypical,often with insidious onset. For pregnant women with pSS, being diagnosed before pregnancy, positive Sj?gren-specific antibody B may reduce adverse outcomes. It is important to address pre-pregnancy examination, early diagnosis and timely intervention to reduce the occurrence of adverse outcomes in pregnant women with pSS.

Objective The existing evidence of exercise rehabilitation in patients undergoing surgery for valvular heart disease was analyzed,described and evaluated by using evidence mapping methods.Methods Systematic reviews and randomized controlled trials on exercise rehabilitation of patients undergoing valvular heart disease surgery were searched from CNKI,Wanfang Data,VIP,CBM,Embase,PubMed,Cochrane Library,Web of Science,Ovid,CINAHL and other databases,and the search period was established until April 23,2024.The quality of the included literature was evaluated,and the feature information of the included literature was visualized in the form of bubble map and table.Results Fifty-one literatures(including 44 randomized controlled trials and 7 systematic evaluations)were finally included.Among the 44 randomized controlled trials,the types of exercise were mainly related to anaerobic exercise(3 literatures),aerobic exercise(11 literatures),flexibility training(8 literatures),and multisport exercise(22 literatures);postoperative inpatient rehabilitation accounted for a relatively high proportion(16 literatures),followed by overall postoperative rehabilitation(13 literatures)and pre-operative prehabilitation(7 literatures).Twenty-seven conclusions were categorized as"beneficial",15 as"possibly beneficial,"and one ach as"unclear"and"no effect".Seven systematic evaluations were subjected to Meta-analysis,and in terms of the design of the included studies,there were only 3 systematic reviews that included randomized controlled trials.Of the study conclusions,three were"beneficial",three were"possibly beneficial"and one was"unclear".Conclusion The evidence mapping shows that exercise rehabilitation is generally beneficial or potentially beneficial in the rehabilitation of valvular heart disease surgery,mainly in the postoperative inpatient rehabilitation phase.High-quality studies are needed to further investigate the effectiveness of exercise programs with different intensities,frequencies,and durations,as well as different valve types,adverse effects of exercise,and other outcome indicators.

Objective To systematically review the efficacy of enhanced recovery after surgery(ERAS)nursing on patients with dissection of aorta.Methods Nine databases,including PubMed,CNKI,etc were searched to identify randomized controlled trials involving dissection of aorta patients undergoing ERAS nursing.The retrieval time was from setting up of the databases until March 2024.Literature quality assessment followed by"Cochrane handbook for systematic reviews of interventions.Version 5.1.0",and Meta-analysis was conducted utilizing software of RevMan 5.4.Results Nine literatures with a total of 723 patients were included.The results of Meta-analysis showed that compared with the conventional nursing model,the application of ERAS nursing model could effectively promote the process of patients'postoperative recovery,and there were significant differences in indicators such as the time of postoperative mechanical ventilation,the time of the first postoperative out-of-bed activity,the time of tubing removal,the incidence of complications,the length of hospital stay,and the degree of perceived pain(P＜0.05).Conclusion Implementing nursing model based on ERAS on dissection of aorta patients can effectively enhance patients'postoperative recovery outcomes,thus worth clinical promotion and application.

Objective To evaluate the effect of mindfulness-based intervention in patients after percutaneous coronary intervention(PCI)through Meta-analysis.Methods Nine databases,including CNKI and PubMed,were searched for randomized controlled trials on the effect of mindfulness intervention in patients after PCI,and the search period was from the establishment of the database to May 31,2024.Two researchers independently screened the literature,extracted data and evaluated the quality,and used Revman 5.4 software for Meta-analysis.Results A total of 11 randomized controlled trials involving 998 patients were included.The results of Meta-analysis showed that compared with conventional care,the use of mindfulness-based intervention therapy could positively improve patients'postoperative anxiety,perceived stress level,mindfulness awareness and other indicators.In terms of safety measures,the incidence of cardiac adverse events was not statistically significant compared with usual care(P＞0.05).Conclusion Mindfulness intervention has a significant effect in patients after PCI.

Objective To investigate the effect of aqueous extract of Scrophularia ningpoensis(AESN)on AMP-activated protein kinase(AMPK)activity in INS-1 cells under high glucose(HG)conditions.Methods INS-1 cells were cultured in HG medium and treated with different concentrations of AESN.The influences of AESN on cell viability and pyroptotic body formation were detected using the CCK-8 assay.Western blotting was used to observe the effects of AESN on AMPK expression and phosphorylation.The effect of AESN on AMPK activity was measured using time-resolved fluorescence resonance energy transfer(TR-FRET)assay.Results Compared with normal glucose controls,INS-1 cells exposed to HG showed decreased cell viabilities and increased formation of pyroptotic bubbles using CCK-8 assay.Western blotting results indicated that HG exposure led to a decrease in intracellular AMPK phosphorylation levels.However,co-incubation with AESN under HG exposure AESN treatment increased the cell viabilities and phosphorylation of AMPK and decreased the pyroptotic bubbles formation in a concentration-dependent manner.In addition,the results of TR-FRET revealed that AESN treatment effectively increased AMPK activity in a concentration-dependent manner.Conclusion AESN has an activating effect on AMPK activity in HG-treated INS-1 cells.

AIM:This study is aimed to investigate the impact of 3,5,6,7,8,3',4'-heptamethoxyflavone(HMF)on the proliferation,invasion,and migration of human colorectal cancer(CRC)cell lines(SW480 and HCT116)and preliminarily explore the underlying molecular mechanisms.METHODS:Human colorectal cancer cells(SW480 and HCT116)cultured in vitro were subjected to various concentrations of HMF(0,12.5,25 and 50 μmol/L)for 48 h.Proliferation levels were assessed using the CCK-8 assay,invasion abilities were examined via the Transwell assay,migra-tion rates were measured using the scratch assay,and oxidative stress levels were determined by the DCF-DA reactive oxy-genation assay.The mRNA expression levels of heme oxygenase-1(HO-1)mRNA and NAD(P)H:quinone oxidoreduc-tase-1(NQO-1)were quantified using RT-qPCR.RESULTS:Treatment with varying concentrations of HMF resulted in a significant reduction in the proliferative capacity of SW480 and HCT116 cancer cells,as was indicated by CCK-8 experi-ments(P<0.05).Transwell assays demonstrated a pronounced attenuation in the invasive potential of SW480 and HCT116 following HMF treatment(P<0.05).Scratch assays highlighted a notable constraint on the migratory capabilities of SW480 and HCT116 after HMF treatment(P<0.05).DCF-DA staining revealed a substantial increase in reactive oxy-gen species(ROS)levels within SW480 and HCT116 cells after HMF treatment(P<0.05).Furthermore,RT-qPCR ex-periments elucidated that HMF markedly suppressed the mRNA expression of antioxidant genes HO-1 and NQO-1.CON-CLUSION:HMF induces oxidative stress response in SW480 and HCT116 cells,consequently inhibiting their prolifera-tion,invasion and migration.

Objective To establish a personalized Stanford type B aortic dissection numerical simulation model, and using computational fluid dynamics (CFD) numerical simulation to obtain the hemodynamic behavior and law of the type B aortic dissection at different stages of development. Methods Based on the theory of three-dimensional model reconstruction, we used CT images of a patient with type B aortic dissection in the Xiamen Cardiovascular Hospital of Xiamen University, relevant medical image processing software to reconstruct a personalized aortic three-dimensional model, and CFD to reconstruct the model which was simulated in fluid mechanics. Results The three-dimensional reconstruction model could intuitively observe the changing trend of the false cavity at different stages of the dissection development. Through fluid mechanics simulation, the blood flow rate, pressure, wall shear stress, vascular wall Von Mises stress and other parameters at different stages of the dissection development were obtained. Conclusion The hemodynamic behavior and law of relevant parameters in the development stage of aortic dissection are analyzed. The combination of the values of relevant parameters and clinical medical detection and diagnosis can well predict the development of the disease, and finally provide more theories and methods for the scientific diagnosis of aortic dissection.

【Objective】 To review the scientific research advances in the field of preschool children′s nutrition from 2012 to 2022, in order to provide reference for relevant policy formulation and further scientific exploration in this area. 【Methods】 High-quality literature published both domestically and internationally between 2012 and 2022 was retrieved through Web of Science (WOS) and China National Knowledge Infrastructure (CNKI) database. Excel and CiteSpace software were applied to visualize the research hotspots and frontier trends. 【Results】 A total of 1 816 English articles and 110 Chinese articles were included in the analysis. The cooperation network density of research institutions and authors was found to be low. Excluding the search terms, the top three English keywords were vitamin A (0.74), intervention (0.67), obesity prevention (0.55); the top three Chinese keywords were "anemia" (0.41), "obesity" (0.38), and "nutritional status" (0.18). In Chinese and English clusters, "anemia" and "physical activity" ranked first, respectively. The latest burst words identified were "dietary pattern" and "diet quality". 【Conclusions】 The number of English literature published in the field of preschool children′s nutrition is increasing, but it has shown a downward trend in the past three years in China. There are few studies in this field in China. The research hotspots primarily focus on the nutritional status of preschool children, with less attention paid to intervention research and methodological exploration. Further research in the field of preschool children′s nutrition in China may need to focus on the external determinants of preschool children′s nutrition, such as parental education, diet and food supply.

Objective To discuss the possible etiology,pathogenesis,clinical features,diagnosis and treatment of epidermoid cysts of the jaw and to provide a reference for clinical diagnosis and treatment.Methods A case of an epi-dermoid cyst in the right mandible with retained deciduous teeth and succedaneous impacted teeth was reviewed and an-alyzed in combination with the relevant literature.Results A patient presented with a mass in the right mandible that had persisted for 1 month after being found at imaging examination.Tooth 83 was retained,and tooth 43 was unerupted.Swelling was characterized by no obvious tenderness,fluctuation,or table tennis sensation and was observed in the lin-gual alveoli of teeth 83,44,and 45.Imaging revealed a low-density shadow in the apex of teeth 83,44,45,and 46,approximately 1.9 cm × 2.6 cm × 1.6 cm in size,which wrapped around the dental crown of tooth 43.Preliminary diag-noses were as follows:right mandibular mass thought to be a dentigerous cyst;impacted tooth 43;and retained primary tooth 83.The mass in the right mandible was removed,and teeth 43 and 83 were extracted under intravenous and inha-lation anesthesia.During the operation,the mass was observed to have a thin cyst wall and contained bean-like residue.Histopathological examination indicated an epidermoid cyst in the right mandible.At the 1-week follow-up examination,the patient reported no discomfort,and the surgical area showed good recovery.According to the literature,epidermoid cysts are benign cysts originating from ectopic ectodermal tissue that can occur throughout the body but rarely in the oral cavity and are even extremely rarer in the jaw.Epidermoid cysts of the jaw,which have no specific clinical manifes-tations,can be confused with odontogenic cysts such as dentigerous cysts and odontogenic tumors.Dental pulp tests and other techniques can serve as a reference for clinicians.The diagnosis is confirmed via histopathology.Surgical removal is a common treatment,with a good prognosis and a low recurrence rate.Conclusion The principle of treatment for an epidermoid cyst of the jaw is similar to that for a jaw cyst.The prognosis is good when the cyst is removed completely.
