Objective To explore the correlation between pre-pregnancy body mass index (BMI) and the risk of difficult airway during labor and delivery through grading changes of Mallampati test (MT). Methods A total of 354 primiparous women who delivered at Obstetrics and Gynecology Hospital of Fudan University from October 2020 to April 2021 were enrolled and categorized into low BMI, normal BMI, and high BMI groups based on pre-pregnancy BMI. Changes in MT grading were analyzed during early labor, postpartum (20 minutes to 1 hour after placental delivery), and 48 hours postpartum. A multifactor logistic regression model was used to analyze the factors increased MT grading postpartum. Results Among the 354 participants, 97 (27.4%) exhibited increased MT grading postpartum, with the proportion of women classified as MT grade 3-4 rising from 39 (11.0%) during early labor to 77 (21.8%) postpartum. By 48 hours postpartum, the number of women with MT grade 3-4 decreased to 21 (5.9%). Multifactor logistic regression analysis showed that low pre-pregnancy BMI (vs high BMI: OR＝2.15, 95%CI 1.02-4.53, P＝0.045) and snoring history during pregnancy (OR＝2.32, 95% CI 1.38-3.90, P＝0.001) were independent risk factors for postpartum MT grading elevation. Conclusions MT grading might increase postpartum in parturients, with low pre-pregnancy BMI and prenatal snoring history identified as significant risk factors for elevated MT grading after delivery.

Objective To establish an ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry(UPLC-QTOF-MS)method for identifying the active ingredients of Zhizi Houpu decoction,and to predict its material basis and mechanism of anti-insomnia effects using network pharmacology.Methods The chemical components of Zhizi Houpu decoction were identified according to UHPLC-QTOF-MS ion fragmentation rule combined with compound library and literature review.Components with oral bioavailability(OB)≥30％and drug-like properties(DL)≥0.18 were selected to construct the Zhizi Houpu decoction-active ingredients-target network.The STRING database and the Database for Annotation,Visualization,and Integrated Discovery(DAVID)were used to screen key target proteins.Subsequently,enrichment analysis was performed for biological processes,molecular functions,cellular components,and signaling pathways.Results A total of 107 chemical components were identified,including 35 compounds related to insomnia and 11 anti-insomnia targets such as AKT serine/threonine kinase 1,tumor protein 53,and prostaglandin-endoperoxide synthase 2.Gene Ontology functional enrichment analysis indicated that Zhizi Houpo decoction may exert its effects through cellular components such as the presynaptic membrane,dendrite,and plasma membrane,by participating in biological processes like chemical synaptic transmission,G protein signaling pathway,and neuron apoptosis,and by regulating molecular functions such as G protein-coupled serotonin receptor activity.Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis revealed that its anti-insomnia effects were mainly concentrated in pathways such as neuroactive ligand-receptor interaction,calcium signaling pathway,serotonergic synapse,and cyclic adenosine monophosphate signaling pathway.Conclusion The anti-insomnia effect of Zhizi Houpo decoction is the result of a synergistic action involving multiple components,multiple targets,and multiple pathways.Its material basis and mechanism of action are primarily related to regulating biological processes such as neurotransmitter metabolism,synaptic function,neuronal apoptosis,and inflammatory response.

Objective To investigate the incidence of intraoperative hypothermia(IH)and rewarming efficacy in elderly patients with different traditional Chinese medicine(TCM)constitutions undergoing general anesthesia.Methods A total of 500 elderly patients undergoing general anesthesia at the First Affiliated Hospital of Guangzhou University of Chinese Medicine from June 2022 to November 2022 were enrolled.The patients were divided into IH group and non-IH group depending on the occurrence of IH.Baseline data of the patients were collected,and univariate and multivariate logistic regression analyses were performed to identify risk factors for IH.A risk prediction model was constructed after value-assignment of influencing factors and its diagnostic efficiency was assessed by receiver operating characteristic(ROC)curve.External validation of the model was conducted in 50 elderly patients undergoing general anesthesia at the same period.From December 2022 to February 2023,80 elderly patients undergoing general anesthesia and complicated with IH were randomized into a control group(routine measures for keeping warm)and an observation group(keeping warm with forced-air-warming blanket)to compare the rewarming efficacy.Results(1)Among 500 elderly patients undergoing general anesthesia,180 cases developed IH,with an incidence of 36.0%.(2)Except for age,sex,type of surgery,American Society of Anesthesiologists(ASA)classification,type of anesthesia,and total fluid output volume,statistically significant differences were presented in body mass index(BMI),TCM constitution type,surgical complexity grading,preoperative core body temperature,operating room temperature,rewarming strategy,surgical duration,anesthesia duration,total fluid intake volume,intraoperative irrigation volume,and intraoperative blood transfusion between the two groups(P＜0.05 or P＜0.01).(3)Multivariate logistic regression analysis identified BMI,TCM constitution type,surgical complexity grading,preoperative core body temperature,operating room temperature,rewarming strategy,anesthesia duration,total fluid intake volume,and intraoperative irrigation volume as independent influencing factors for the occurrence of IH in elderly patients undergoing general anesthesia.ROC curve analysis demonstrated that the area under the curve(AUC)of the constructed risk prediction model was 0.816,with a sensitivity of 74.40%and a specificity of 77.50%.(4)In an external validation cohort of 50 elderly patients undergoing general anesthesia(19 IH cases versus 31 non-IH cases),the constructed risk prediction model exhibited a sensitivity of 73.68%and a specificity of 77.42%.(5)The observation group exhibited lower tympanic temperature upon post-anesthesia care unit(PACU)admission,shorter rewarming time and PACU stay duration,faster rewarming rate,and lower incidence of shivering than the control group,the differences being statistically significant(P＜0.05 or P＜0.01).Conclusion IH is common in elderly patients undergoing general anesthesia,particularly in those under the conditions of low BMI,qi/yang/blood deficiency constitutions,major surgery,low preoperative core body temperature,low operating room temperature,passive rewarming,prolonged anesthesia,high fluid intake volume,and high and intraoperative irrigation volume.The constructed risk prediction model demonstrates favorable diagnostic performance.Proactive use of forced-air-warming blankets effectively improves rewarming outcomes in elderly patients undergoing general anesthesia and complicated with IH.

Objective To investigate the value of secreted frizzled-related protein 1(SFRP1),GATA binding protein 3(GATA3)combined with human papillomavirus deoxyribonucleic acid(HPV-DNA)in predicting the risk of postoperative recurrence of high-grade cervical intraepithelial neoplasia(CIN)with positive thin-prep cytologic test(TCT).Methods A total of 200 patients with high-grade CIN and positive TCT results from July 2021 to July 2023 were selected as study subjects.All patients underwent cervical conization,and were divided into recurrence group and non-recurrence group according to the recurrence status one year after surgery.The clinical data,HPV-DNA viral load,and the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cer-vical tissues were compared between the two groups.The HPV-DNA viral load,SFRP1 mRNA,and GATA3 mRNA expression levels in patients with different CIN grades were compared,and their cor-relations with CIN grade and the risk of postoperative recurrence were analyzed.The predictive val-ues of SFRP1,GATA3,and HPV-DNA for the risk of postoperative recurrence were analyzed.Results Among 200 patients,2 were lost during the follow-up period.The recurrence group(n=30)had higher proportions of CIN grade Ⅲ,glandular involvement,positive surgical margins,high-risk human papillomavirus(HPV),higher HPV-DNA viral load,and a higher proportion of HPV positivity at 6 months after surgery compared with the non-recurrence group(n=168),and the differences were statistically significant(P＜0.05).The relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues of the recurrence group were lower than those of the non-recur-rence group,and the differences were statistically significant(P＜0.001).The HPV-DNA level in pa-tients with CIN grade Ⅲ was higher than that in those with CIN grade Ⅱ,and the relative expres-sion levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were lower than those in patients with CIN grade Ⅱ,and the differences were all statistically significant(P＜0.001).Spearman cor-relation analysis showed that HPV-DNA was positively correlated with CIN grade(P＜0.001),while the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were neg-atively correlated with CIN grade(P＜0.001).Logistic regression analysis showed that HPV-DNA,the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were independ-ent influencing factors for the risk of postoperative recurrence(P＜0.001).The receiver operating characteristic(ROC)curve results showed that the areas under the curve(AUCs)for predicting the risk of postoperative recurrence by HPV-DNA,the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were 0.787,0.781,and 0.764,respectively,with sensitivities of 80.00％,76.67％,and 76.67％,and specificities of 74.40％,73.81％,and 67.26％,respec-tively.The AUC for the combined prediction of the risk of postoperative recurrence by the three indica-tors was 0.924,with a sensitivity of 80.00％and a specificity of 93.45％,which was superior to the pre-dictive values of each indicator alone(Z=3.159,3.306,4.018,P＜0.001).Conclusion HPV-DNA,SFRP1,and GATA3 in cervical tissues have certain predictive values for the risk of postoperative re-currence in patients with high-grade CIN and positive TCT results,and combined detection can im-prove the predictive efficacy.

Objective: To explore the clinical application value of neural network technology,and to screen the clinical early warning indicators of severe hand-foot-mouth disease(HFMD) by constructing a back propagation neural network(BPNN) model. Methods: The clinical data of children with HFMD admitted to the Department of Infectious Diseases and Pediatrics of the First Affiliated Hospital of Xinxiang Medical University from January2019 to January 2023 were collected.The data were divided into 70% training samples and 30 % test samples using SPSS Modeler 18.0.The BPNN model and Logistic model were constructed to compare and evaluate the prediction accuracy and screening effect of the model. Results: The clinical data of 589 children were collected and analyzed,including 324 cases in the mild group and 265 cases in the severe group.The prediction accuracy of the test set(n=178) of BP neural network model and Logistic regression model was 82.02% and 84.83%,respectively.The area under the ROC curve(95% CI) was 0.791(0.749-0.834) and 0.625(0.577-0.674),respectively.Among the predictive variables output by the BPNN model,the top five factors that had the greatest impact on the grouping were highest body temperature,duration of fever,glutamyl transpeptidase,aspartate aminotransferase,and globulin.There were 3 of the top 10 overlaps in the importance of the predictive variables output by the two models,which were the highest body temperature,duration of fever and limb shaking. Conclusion The BPNN model and Logistic regression model perform well in screening and verifying the risk factors of severe hand-foot-mouth disease,but the comprehensive prediction performance of BP neural network model is better.The top five influencing factors of severe HFMD screened by the BPNN model are the highest body temperature,duration of fever,glutamyl transpeptidase,aspartate aminotransferase and globulin.

Objective To investigate the incidence and severity of enamel demineralization during clear aligner treatment and provide reference for clinical medical nursing work.Methods A total of 151 patients(3 507 teeth)undergoing clear aligner treatment in our hospital from 2015 to 2022 were collected.The enamel demineralization before and after treatment was compared,and the enamel demi-neralization index(EDI)was calculated to evaluate the severity of demineralization.The incidence and severity of enamel demineraliza-tion were analyzed statistically,and the differences among different genders,ages and dental positions were compared.Results Enam-el demineralization occurred in 84 patients during treatment,with an incidence rate of 55.63%.Gender and treatment time had no effect on the incidence,and the incidence of adolescent patients was higher than that of adult patients.Among the investigated 3 507 teeth,601 teeth had enamel demineralization,and the incidence rate was 17.14%.The incidence of maxillary anterior teeth and mandibular posterior teeth was higher;the incidence of right teeth was significantly higher than that of left teeth,and the incidence of teeth with ad-hesive attachments was also significantly increased.88%of the enamel demineralization lesions were 1－2 degrees,and the degree of enamel demineralization was similar in male and female patients.But the degree in adolescents was significantly higher than that in adult patients.The average EDI value of maxillary anterior teeth was significantly higher than that of mandible,but that of maxillary posterior teeth was significantly lower than that of mandible.The average EDI value of right teeth was significantly higher than that of left.Conclusion The incidence of enamel demineralization is high in the process of clear aligner treatment,and teenagers are suscep-tible to it.The demineralization of teeth is significantly different among different tooth positions,and adhesive attachments will increase the risk of enamel demineralization.Therefore,medical staff should take active and effective measures in the prevention and treatment of enamel demineralization.

This paper analyzes a patient's clinical and laboratory characteristics with lumbar disc herniation invaded by Brucella in the bloodstream, causing brucellar spondylitis with paravertebral and psoas abscesses in Hebei Province in 2022. A 50-year-old male patient presented with lower back pain two months after physical exertion, and the symptoms were alleviated after bed rest but recurred intermittently. A Lumbar CT scan indicated disc protrusion, and the patient experienced multiple episodes of fever during this period. Twelve days before admission, the patient developed unexplained swelling pain and numbness in the right lower limb, which persisted despite bed rest. On October 21, 2022, tissue and abscess specimens were directly cultured and Gram-stained, along with blood culture, Brucella antibody testing, and CT imaging. Gram staining of the pus sample revealed tiny, sand-like bacterial bodies, suspected to be Brucella species. Paravertebral abscess samples and positive blood cultures were cultured on blood agar plates, yielding Brucella melitensis. Brucella antibody tests were positive. CT scanning of the lumbar vertebrae revealed bone destruction from L3 to L5, with swelling of the paravertebral soft tissues and left psoas muscle. The patient was diagnosed with brucellar spondylitis, with the accompanying paravertebral and psoas abscesses being a rare complication of brucellar spondylitis. Conservative treatment was ineffective, so surgery was performed to relieve nerve compression symptoms, along with the administration of anti-Brucella medication. The patient was discharged 15 days and continued anti-Brucella treatment post-discharge. One year follow-up showed the patient was cured with no recurrence. Brucellosis is characterized by sporadic outbreaks, with atypical clinical symptoms that can easily result in missed or incorrect diagnoses. Timely blood cultures are crucial for early diagnosis and effective anti-Brucella treatment to prevent disease progression and dissemination through the bloodstream, which could lead to multiple organ involvement, exacerbating the condition and hindering recovery.

Objective:To explore the relationship of infertility-related stress and depression of infertility women, and the effect of coping style and resilience in it.Methods:A cross sectional study was conducted in 230 infertility women who treated with Assisted Reproductive Technology in Reproductive Medical Center of the First Affiliated Hospital of Soochow University using convenience sampling method from April 2020 to April 2021 with self-made general information questionnaire, Fertility Problem Inventory, Simplified Coping Style Questionnaire, 10-item Connor-Davidson Resilience Scale and Patients' Health Questionnaire Depression Scale-9 item. And correlation and effect analysis was conducted.Results:Two hundred and nineteen questionnaires were finally collected, the effective recovery rate was 95.2%(219/230). The score of Fertility Problem Inventory was (136.21 ± 27.38) points, the score of Simplified Coping Style Questionnaire was (34.26 ± 7.66) points, the score of 10-item Connor-Davidson Resilience Scale was (27.50 ± 6.78) points, the score of Patients' Health Questionnaire Depression Scale-9 item was (4.26 ± 3.83) points. Correlation analysis results showed that infertility-related stress of infertility women was positively correlated with negative coping ( r=0.20, P<0.01) and depression ( r=0.26, P<0.01), negative coping was positively correlated with depression ( r=0.23, P<0.01). Effect analysis results showed that negative coping had a partial mediating effect between infertility-related stress and depression, and the mediating effect size was 0.05, accounting for 15.63% of the total effects. Resilience moderated the second half path of the mediation relationship ( β=-0.137, t=-2.11, P<0.05). Conclusions:The infertility-related stress is a positive predictor of depression. Negative coping has a mediating effect between infertility-related stress and depression, and resilience moderates the effect of negative coping on depression.
