ObjectiveTo investigate the main risk factors for liver cirrhosis in chronic hepatitis B （CHB） patients with high metabolic risk， to establish a noninvasive predictive model， and to compare the diagnostic efficiency of this model and other models including fibrosis-4 （FIB-4）， aspartate aminotransferase-to-platelet ratio index （APRI）， gamma-glutamyl transpeptidase-to-platelet ratio （GPR）， and Forns index. MethodsA total of 527 CHB patients with high metabolic risks who were admitted to The Second Affiliated Hospital of Guangxi Medical University from September 1， 2017 to October 31， 2022 were enrolled as subjects， and they were randomly divided into modeling group with 368 patients and validation group with 159 patients at a ratio of 7∶3. The LASSO regression analysis and the multivariate Logistic regression analysis were performed for the modeling group to identify independent risk factors， and a nomogram model was established. The receiver operating characteristic （ROC） curve， the calibration curve， and the decision curve analysis were used to validate the nomogram prediction model in the modeling group and the validation group and assess its discriminatory ability， calibration， and clinical practicability. The Delong test was used to compare the area under the ROC curve （AUC） of the nomogram prediction model and other models. ResultsThe multivariate Logistic regression analysis showed that prealbumin （odds ratio ［OR］ = 0.993， 95% confidence interval ［CI］： 0.988 — 0.999， P= 0.019）， thrombin time （OR=1.182， 95% CI： 1.006 — 1.385， P=0.047）， log₁₀ total bilirubin （TBil） （OR=1.710， 95%CI： 1.239 — 2.419， P=0.001）， and log₁₀ alpha-fetoprotein （AFP） （OR=1.327， 95%CI： 1.052 — 1.683， P=0.018） were independent influencing factors for liver cirrhosis in CHB patients with high metabolic risks. A nomogram model for risk prediction was established based on the multivariate analysis， which had an AUC of 0.837 （95%CI： 0.788 — 0.888）， a specificity of 73.5%， and a sensitivity of 84.7%， as well as a significantly higher diagnostic efficiency than the models of FIB-4 （0.739）， APRI （0.802）， GPR （0.800）， and Forns index （0.709） （Z=2.815， 2.271， 1.989， and 2.722， P=0.005， 0.017， 0.045， and 0.006）. ConclusionThe nomogram model established based on prealbumin， thrombin time， log₁₀ TBil， and log₁₀ AFP has a certain clinical application value.

Objective To identify the impact of glucose variability(GV)on the development of gestational hyper-tension(GH)in patients with gestational diabetes mellitus(GDM),and to find the differences between various GV metrics as well as to evaluate their predictive value in management strategy development.Methods A total of 127 pregnant women diagnosed with GDM were included in this study.After the diagnosis of GDM,continuous glu-cose monitoring(CGM)and blood pressure measurements were performed,and the occurrence of gestational hyper-tensive disorders was recorded.Indices of glucose variability were calculated using an automated software EasyGV version 9.0.Results The results revealed an association between gestational hypertension and glucose variability in GDM patients.Among the study participants,2 cases(1.6％)were diagnosed with preeclampsia and 9 cases(7.1％)were diagnosed with gestational hypertension.TBR％(time below range)showed a significantly negative correlation with diastolic blood pressure at 29-32 weeks of gestation and with both diastolic and systolic blood pres-sure during delivery.TIR％(time in range)showed a negative correlation with the rate of change in systolic blood pressure between two prenatal visits.CONGA(continuous overlapping net glycemic action)emerged as an inde-pendent predictor of gestational hypertension(OR:3.648;95％CI:1.046,12.721;P=0.042).When CONGA exceeded 4.856,the risk of gestational hypertension in GDM patients increased.Conclusions Blood glucose varia-tion is an independent factor affecting the occurrence of pregnancy-induced hypertension in GDM women.This study suggests new targets for the use and management of CGM in pregnant women with GDM.For GDM patients at high risk of hypertensive disease during pregnancy,blood glucose should be kept at a reasonable and stable level.

Objective To evaluate the influencing factors of aspiration in neurological critically ill patients by Meta-analysis.Methods PubMed,Embase,Web of Science,CNKI,and Wanfang Data were searched from inception to 1 October,2023,to obtain relevant studies on influencing fac-tors of aspiration in neurological critically ill patients.The literature screening,data extraction and quality evaluation were completed by two researchers.RevMan 5.4 and Stata 13.0 software were ap-plied for pooled Meta-analysisand assessed publication bias,respectively.Results A total of 8 arti-cles,including 1,315 neurocritical care patients,were included in this study.Nine influencing factors related to aspiration were extracted for Meta-analysis.The Meta-analysis results showed that the three influencing factors that caused aspiration in neurocritical care patients were stroke history(OR=5.03,95％CI,2.71 to 9.32,P＜0.000 01),National Institutes of Health Stroke Scale(NIHSS)score＞10(OR=3.35,95％CI,1.75 to 6.42,P=0.000 3),and gastric residual volume＞150mL(OR=7.13,95％CI,2.55 to 9.96,P=0.001).Conclusion This study provides a scientific basis for clinical healthcare professionals to early identify high-risk patients for aspiration,take targeted inter-vention measures,and prevent the occurrence of aspiration.

Objective To evaluate the therapeutic effects of different intracranial pressure lower-ing regimens in patients with acute large-area cerebral infarction based on electrical impedance tomo-graphy(EIT)technology.Methods A total of 75 patients with acute large-area cerebral infarction were selected as the study subjects and randomly divided into study group(n=40,using mannitol combined with albumin to decrease intracranial pressure)and control group(n=35,using mannitol alone to decrease intracranial pressure).EIT technology was used to continuously monitor the changes in intracranial pressure within 48 hours in the patients.Clinical data of the two groups were collected,and the 24-hour intracranial pressure change rate,48-hour intracranial pressure change rate,ICU stay duration,hospitalization duration,antibiotic use duration,and National Institutes of Health Stroke Scale(NIHSS)score at discharge were observed and compared between the two groups.A 90-day sur-vival follow-up was also conducted.Results There was no statistically significant difference in the 24-hour intracranial pressure change rate between the two groups(P＞0.05).The 48-hour intracrani-al pressure change rate in the study group was higher than that in the control group,and the difference was statistically significant(P＜0.05).The ICU stay duration,hospitalization duration,and antibiotic use duration in the study group were all shorter than those in the control group,and the NIHSS score at discharge in the study group was lower than that in the control group,with statistically significant differences(P＜0.05).The follow-up results showed that the survival duration in the study group was longer than that in the control group,and the 90-day cumulative survival rate in the study group was higher than that in the control group,but the differences were not statistically significant(P＞0.05).The modified Rankin Scale score in the study group was lower than that in the control group,and the difference was statistically significant(P＜0.05).Conclusion Compared with the use of mannitol alone,early use of mannitol combined with albumin can effectively decrease the in-tracranial pressure within 48 hours,shorten the hospitalization duration,and improve neurological function in patients with acute large-area cerebral infarction.

Objective To investigate the clinical efficacy and impact on psycho-behavioral as-pects of sublingual immunotherapy with dermatophagoides farinae drops in children with multiple al-lergies and young-age allergic rhinitis(AR).Methods A total of 139 children with AR sensitized to mites who were treated at the Second Affiliated Hospital of Nanjing Medical University were retrospec-tively selected.Based on the types of allergens,they were divided into single-allergen group and mul-tiple-allergen group,and into young-age group(≤4 years old)and older-age group(＞4 years old)according to age.Visual Analogue Scale(VAS),Total Nasal Symptom Score(TNSS),Child Behav-ior Checklist(CBCL)score,and serum total immunoglobulin E(IgE)levels were compared before treatment and at 6 and 12 months after treatment.Results A total of 123 children completed one-year of sublingual immunotherapy and clinical observation.Compared with pre-treatment,the VAS scores,TNSS,and serum total IgE concentrations of children decreased at 6 and 12 months after desensitization treatment.Moreover,the VAS scores,TNSS,and serum total IgE concentrations at 12 months of treatment were lower than those at 6 months(P＜0.05).Compared with pre-treatment,after 12 months of desensitization treatment,the scores of social withdrawal,anxiety/depression,somatic complaints,and hyperactivity items in children decreased(P＜0.05).After 6 and 12 months of desensitization treatment,the VAS scores and TNSS in the multiple-allergen group were lower than those in the single-allergen group(P＜0.05).Compared with pre-treatment,the serum total IgE concentrations in both the single-allergen group and the multiple-allergen group decreased at 6 and 12 months after treatment,with statistically significant differences(P＜0.05).Before treat-ment,the serum total IgE concentration in the older-age group was higher than that in the young-age group(P＜0.05).Conclusion Sublingual immunotherapy can achieve significant efficacy in chil-dren with multiple allergies and young-age(≤4 years old)AR,and shows better efficacy in chil-dren with multiple allergies.Meanwhile,this treatment is also beneficial for reducing the occurrence of psycho-behavioral problems in children,especially for improving hyperactive behavior.
