Objective To explore the trajectory of psychological symptom clusters in pregnant women with assisted reproductive technology(ART),and analyze the influencing factors of each trajectory subgroups,in order to provide a theoretical basis for the management of psychological health during pregnancy in pregnant women with ART.Methods A total of 205 pregnant women who had conceived using ART were sampled from the obstetrics clinic of a tertiary hospital in Nanjing from August 2023 to April 2024 using a convenient sampling method.The baseline data were assessed by general information questionnaire,Symptom Checklist-90,Distress Disclosure Index and Positive Psychological Capital Questionnaire at 10-14 weeks gestation,and the follow-up information was assessed by Symptom Checklist-90 at 22-26 weeks of gestation and 34-38 weeks of gestation.Exploratory factor analysis was used to extract symptom clusters;the latent class growth mixture model was used to identify the track categories;the multiple logistic regression analysis was used to analyze the influencing factors of the track.Results 180 cases were finally included.By exploratory factor analysis,5,4 and 5 factors were extracted at 3 time points respectively.Trajectories of psychological symptom clusters in pregnant women with ART is divided into 3 potential classes:low level-slow relieving group(28.89％),high level-significant increasing group(6.11％),medium level-slow increasing group(65.00％).Logistic regression analyses showed that duration of infertility,number of ART,literacy,pain self-expression and positive psychological capital were influential factors in the potential categories of psychological symptom clusters in pregnant women conceived with ART(all P＜0.05).Conclusion The trajectory of psychological symptom clusters in pregnant women with ART was divided into 3 potential classes.Medical workers could develop corresponding interventions based on the influencing factors and implement comprehensive and efficient symptom management.

Objective:To investigate dietary patterns under social jet lag in pregnant women with gestational diabetes mellitus (GDM) and analyze its relationship with blood glucose control and delivery outcomes, to provide a reference for comprehensive management of pregnant women with GDM.Methods:A cross-sectional study method was used to select pregnant women with GDM during their stay in the obstetrics ward of the Obstetrics and Gynaecology Hospital of Nanjing Medical University from October 2022 to December 2023 as the study population. Social jet lag and dietary information were collected using Simplified Food Frequency Questionnaire and Self-assessment Questionnaire on Social Jet Lag. Spearman correlation analysis was used to analyze the correlation between dietary patterns and blood glucose control as well as delivery outcomes. Receiver operating characteristic curve was used to analyze the predictive performance of social jet lag, dietary patterns and fasting blood glucose for cesarean section.Results:A total of 350 pregnant women with GDM were included, 140 pregnant women with social time lag, aged (31.97 ± 3.88) years old; 210 pregnant women without social time lag, aged (32.32 ± 3.91) years old. The plant-based dietary pattern factor, fast food dietary pattern factor, and the intakes of protein, fat, and carbohydrates of pregnant women with social jet lag were -0.06 (-0.25, 0.32) and 0.08 (-0.43, 0.66), (119.57 ± 89.77) g, (82.69 ± 59.48) g, (228.77 ± 140.18) g, compared with pregnant women without social jet lag [-0.21 (-0.39, 0.08), -0.24 (-0.57, 0.07), (86.29 ± 47.75) g, (57.31 ± 37.86) g, (170.79 ± 85.56) g], the differences were statistically significant ( Z=-2.39, -2.86, t=81.43, 90.78, 88.34, all P<0.05). The social jet lag of GDM women was positively correlated with plant-based dietary patterns, fast food dietary patterns, fasting blood glucose, glycated hemoglobin and cesarean section ( r values were 0.19-0.24, all P<0.05). The plant-based dietary pattern of pregnant women with GDM was negatively correlated with fasting blood glucose and cesarean section ( r=-0.17, -0.24, both P<0.05), while the fast food dietary pattern was positively correlated with fasting blood glucose and cesarean section ( r=0.20, 0.19, both P<0.05). The area under the curve in the combined prediction of multiple factors such as social jet lag, plant-based dietary pattern, fast food dietary pattern and fasting blood glucose for the outcome of cesarean section during pregnancy was 0.742. Conclusions:The dietary structure of GDM women with social jet lag is unreasonable, consume more carbohydrates, sugar, and fats, which are associated with poor glycemic control and increased cesarean section rate. Medical staff should be alerted to social jet lag preferences and dietary intake of GDM and include them in the risk assessment of adverse outcomes of GDM, give timely correction and strengthen management, which can provide a reference for early preventive interventions for GDM with different risk stratification.

Objective:To investigate the attributes and influencing factors of care needs for maternal after perinatal loss, and to provide a reference for promoting maternal physical and mental health and improving the quality of care.Methods:From February to June of 2023, a cross-sectional study was used, 222 maternal after perinatal loss were selected by the convenience sampling method and completed a battery of questionnaires, including a general information questionnaire, the Distress Thermometer (DT), the Perceived Social Support Scale (PSSS), the Attitudes Toward Seeking Professional Psychological Help Scale-Short Form (ATSPPH-SF) and Kano Model-based Questionnaire on Care Needs for Maternal after Perinatal Loss.Results:A total of 207 maternal after perinatal loss were included in the complete data, (31.12±4.55) years old, (68.64 ± 10.70) of PSSS, (16.10 ± 3.43) of ATSPPH-SF. The care needs for maternal after perinatal loss included 4 must-be quality, 8 one-dimensional quality and 13 attractive quality. Multiple linear regression analysis showed that education level ( t=2.28), the PSSS score ( t=2.15) and the ATSPPH-SF score ( t=3.94) were the main influencing factors of care needs for maternal after perinatal loss (all P<0.05). Conclusions:Health care professionals should gradually improve the nursing service system according to the priority division of care needs attributes of maternal after perinatal loss, and develop personalized care according to different influencing factors.

Objective:To evaluate the impact of assisted reproductive technology (ART) on postpartum breastfeeding outcomes.Methods:This paper electronically retrieved the China Biology Medicine disc, China National Knowledge Infrastructure, VIP, WanFang Data, PubMed, Embase, Web of Science, and Cochrane Library. The search period was from database establishment to March 15, 2023. After independent literature search, screening, data extraction, and quality evaluation by two researchers, Meta-analysis was conducted using R 4.2.2 software.Results:A total of 11 articles were included. Meta-analysis showed that compared with naturally conceived mothers, the rates of exclusive breastfeeding at 1th week postpartum ( RR=0.84, 95% CI: 0.73-0.97), exclusive breastfeeding at 6th months postpartum ( RR=0.77, 95% CI: 0.61-0.98), and the incidence of breastfeeding for >6 months postpartum ( RR=0.71, 95% CI: 0.53-0.96) were decreased, and the rate of artificial feeding at 12th months postpartum ( RR=1.09, 95% CI: 1.02-1.17) was increased. However, there were no statistically significant differences in the rate of artificial feeding at 8th months postpartum, the incidence of breastfeeding duration >12 months, and the incidence of breastfeeding difficulties ( P>0.05) . Conclusions:ART reduces the rate of exclusive breastfeeding in postpartum 1th week and 6th months, and the incidence of postpartum breastfeeding duration>6 months, and increases the artificial feeding rate in postpartum 12th months. However, the impact of ART on the incidence of breastfeeding difficulties is not yet clear and still needs to be further demonstrated by high-quality studies.

Objective To explore and analyze the feasibility of using indocyanine green(ICG)near-infrared fluores-cence(NIF)imaging technology for the early diagnosis of oral potential malignant disorders and oral squamous cell car-cinoma.Methods 7,12-Dimethylbenz[a]anthracene in acetone solution was used to induce various pathological models of buccal mucosal lesions(mild/moderate dysplasia,severe dysplasia,squamous cell carcinoma)in golden hamster.ICG-NIF was conducted for the quantitative analysis of the fluorescence signal of lesion tissue,and evaluation of the diagnos-tic and discriminative capabilities of the ICG-NIF technology for mucosal lesions in various pathological states.Immuno-histochemical staining was perform to examine the mi-crovessel density(MVD)and microlymphatic vessel den-sity(MLVD)of mucosa in various pathological states and explore the histological reasons underlying the differ-ences in fluorescence signals.Results The results of ICG-NIF fluorescence quantitative analysis reveal the higher fluorescence intensity of mucosal lesions in the experimental group compared with that of the normal mucosa on the control side,with statistical differences(P＜0.05).Moreover,the more severe the malignancy of mucosal lesions in the experimental group,the higher the fluorescence intensity.According to histopathological analysis,the malignant pro-gression of mucosal lesions in golden hamsters was accompanied with an increase in MVD(P＜0.05)and a decrease in MLVD(P＜0.05).Conclusion The abnormal proliferation of mucosal lesions in golden hamsters exhibits a difference in ICG-NIF fluorescence signal compared with normal mucosal tissue.Fluorescence quantitative analysis methods can provide assistance in differentiation and show potential for clinical applications.

Objective To investigate the prevalence of tick-borne rickettsial infections in selected areas of Liupanshui City, Guizhou Province, 2023, so as to provide insights into the management of tick-borne rickettsioses in the city. Methods Ticks were captured from the body surface of bovines and sheep in Gaoxing Village, Dashan Township, Liupanshui City, Guizhou Province during the period between April and June, 2023, and tick species were identified using morphological and molecular biological techniques. In addition, tick-borne Rickettsia was identified using a nested PCR assay, including spotted fever group rickettsiae (SFGR), Coxiella spp., Anaplasma spp., Ehrlichia spp., and Orientia spp., and positive amplified fragments were sequenced and aligned with known sequences accessed in the GenBank database. Results A total of 200 ticks were collected and all tick species were identified as Rhipicephalus microplus. Nestle PCR assay combined with sequencing identified ticks carrying Candidatus Rickettsia jingxinensis (40.50%), Coxiella burnetii (1.50%), and Coxiella-like endosymbionts (27.00%), and Anaplasma spp., Ehrlichia spp. or Orientsia spp. was not detected. Conclusions R. microplus carried Candidatus R. jingxinensis, C. burnetii, and Coxiella-like endosymbionts in selected areas of Liupanshui City, Guizhou Province. Intensified monitoring of tickborne rickettsial infections is needed in livestock and humans to reduce the damages caused by rickettsioses.

Objective: To evaluate the clinical effect of clear aligners in the anterior region in non-extraction cases by establishing a three-dimensional model of crown-root fusion to guide clinical application. Methods: Eleven patients visiting the orthodontic department of Xuzhou Stomatological Hospital from December 2020 to December 2021 were collected, and the orthodontic plan was designed using Maestro 3D Dental Studio scheduling software to obtain the expected three-dimensional model of the patient's orthodontic treatment result. CBCT, intraoral scan, and 3D reconstruction software were used to create a postoperative model of the patient. The crown and root data were aligned in Geomagic Studio 2014, and differences in torque and axial inclination between the actual model after treatment and the predicted model of the anterior teeth before treatment were compared in 3-matic. Results: The actual torque angles of the anterior teeth were all smaller than the predicted angles before treatment, with the highest realization rate of 77.55% for lateral incisors and the lowest of 60.70% for central incisors; the actual axial inclination angles of the anterior teeth were also smaller than the predicted angles before treatment, with the highest realization rate of 81.49% for central incisors and the lowest of 74.95% for cuspids. Conclusion A digital model of crown-root integration based on a combination of 3D reconstruction and intraoral scanning techniques is advantageous in assessing the efficacy of clear aligners. In non-extraction cases with clear aligner, the efficiency of movement is higher for small areas of the anterior region.

Objective To evaluate the effect and safety of catheter constant drainage combined with pericardial perfusion lentinan in treatment of patients with malignant pericardial effusion caused by lung cancer.Methods One hundred and eighteen patients with malignant pericardial effusion caused by lung cancer were divided into 2 groups by table of random digit,the treatment group (56 cases) was treated by pericardial perfusion lentinan after catheter constant drainage by central venous catheter,and the control group (62 cases) was treated by pericardial perfusion cisplatin after catheter constant drainage by central venous catheter.The therapeutic effect and adverse reaction were contrasted between the two groups.Results There was no significant difference in effective rate between treatment group and control group [89.3％(50/56) vs.83.9％ (52/62),x2 =0.736,P =0.391].The adverse reaction rate of treatment group was significantly lower than that of control group [8.9％ (5/56) vs.24.2％ (15/62),x2 =4.871,P =0.027].There was no significant difference in recurrence rate between treatment group and control group [14.3％(8/56) vs.11.3％(7/62),x2 =0.004,P =0.948].Conclusions Catheter constant drainage combined with pericardial perfusion lentinan for malignant pericardial effusion caused by lung cancer is safety and effective,and can be widely applied to clinical application.
