Objective:To investigate the status and influencing factors of substantial weight retention in patients with gestational diabetes mellitus (GDM) in early postpartum.Methods:This cross-sectional study employed a convenience sampling method to select 373 patients with GDM who underwent a 6-week postpartum health check at the Postpartum Health Clinic of Women′s Hospital of Nanjing Medical University from February to July in 2023. According to postpartum weight retention (PPWR) on the survey day, the participants were divided into a substantial PPWR group (≥5 kg, 139 cases) and a non-substantial PPWR group (<5 kg, 234 cases). Independent sample t-tests and χ2 tests were used to compare differences in demographic data, clinical data, and biochemical indicators between the two groups. Binary logistic regression was used to analyze the influencing factors of early substantial postpartum weight retention in patients with GDM. Results:A total of 37.27% (139/373) of GDM patients experienced substantial postpartum weight retention at 6 weeks postpartum. The rates of diabetes in family history, excessive gestational weight gain, gestational hypertension, and infant neonatal intensive care unit (NICU) admission in substantial PPWR group were all significantly higher than those in the non-substantial PPWR group (32.37% vs 23.08%, 73.38% vs 20.09%, 13.67% vs 5.56%, 21.58% vs 9.83%) (all P<0.05); but the proportion of overweight or obese before pregnancy and postpartum self-monitoring of blood glucose were both lower in the substantial PPWR group than those in the non-substantial PPWR group (25.18% vs 41.03%, 17.99% vs 27.78%)(all P<0.05). Binary logistic regression indicated that family history of diabetes ( OR=2.826, 95% CI: 1.517-5.265), excessive gestational weight gain ( OR=19.240, 95% CI: 10.360-35.732), and infant NICU admission ( OR=2.447, 95% CI: 1.150-5.205) were positively related to the occurrence of substantial weight retention in patients with GDM in early postpartum, whereas pre-pregnancy overweight or obesity ( OR=0.189, 95% CI: 0.100-0.360) was negatively correlated to substantial weight retention in patients with GDM in early postpartum (all P<0.05). Conclusion:Substantial weight retention is prevalent among GDM patients in early postpartum, which is significantly influenced by family history of diabetes, pre-pregnancy overweight or obesity, excessive gestational weight gain, and infant NICU admission history.

BACKGROUND: The prevalence of obesity and overweight in childhood has increased dramatically over the past decades globally. Thus, the risk factors of overweight and obesity in children and adolescents must be studied. OBJECTIVES: This study aimed to reveal the prevalence of childhood obesity and examine the relationship between socioeconomic status (SES) and z-body mass index (z-BMI) via parental obesity and dietary intake using path analysis. METHODS: Stratified cluster sampling was used to select 17,007 participants aged 6-12 years on two avenues per region in urban, suburban, and rural areas. Path analysis was conducted to examine the mediators between SES and z-BMI. RESULTS: The prevalence rates of overweight and obesity were 13.36% and 8.60%, respectively, and were positively correlated with the father's education level, family income, a birth weight > 3000g, a parental obesity history, vegetable intake and red meat intake (all P < 0.05). Four mediators (paternal obesity history, red meat intake, vegetable intake, and nutritional supplements) were observed, and the four path analyses were significant (all P < 0.05). The adjusted total effects on z-BMI were significant for income (β CONCLUSIONS The prevalence of overweight/obesity in children was notable, and the relationship between SES and z-BMI was mediated by paternal obesity history and dietary intake.

Objective:To evaluate an anticoagulation management method based on mobile health technology and artificial intelligence.Methods:The study was a single-center, prospective, randomized, controlled, non-inferiority clinical trial. From November 2017 to September 2018, 67 patients who received warfarin therapy after mechanical valve replacement were consecutively enrolled and randomized into two groups: 34 were randomized to intervention group and 33 to control group. The intervention group was managed via Anticlot Assistant and the control group was handled as routine care. Evaluations were performed at least 3 months after enrollment and ended on 30 September 2019. Non-inferiority was evaluated using one-sided tests with a non-inferiority margin set 11.0% for time in therapeutic range (TTR) and 10.0% for the percentage of international normalized ratio (INR) in the therapeutic range.Results:The mean TTR was (58.2±23.4)% in the intervention group and (54.8±23.6)% in the control (the difference: 3.4%; low limit of one-side 95% confidence interval for the difference: -6.4%; and P value for non-inferiority was 0.009). The percentage of INR in the therapeutic range was (55.4±21.9)% in the intervention group and (52.8±22.5)% in the control (the difference: 2.6%, low limit of one-side 95% confidence interval for the difference: -6.6%; and P value for non-inferiority was 0.012). Conclusion:The outcomes of patients managed via the anticoagulation management method base on mobile health technology and artificial intelligence are not inferior to those handled as routine care.

Objective    To verify the reliability of Anticlot Assistant, a patient self-management system for warfarin therapy assisted by artificial intelligence. Methods    It was a single-center, prospective cohort study. The eligible 34 participants were recruited consecutively between November 29, 2017 to September 27, 2018 and managed by warfarin therapy via Anticlot Assistant. The recommendations of Anticlot Assistant were examined and verified by the doctors to ensure the security. Medical records were exported from the the background management system. An univariate analysis compared the outcomes between accepted and overridden records and a logistic regression model was built to determine independent predictors of the outcomes. The research team analyzed 153 medical records, which were from 18 participants and were input by 19 doctors. There were 97 records with doctor accepting the suggestion and 56 records with doctor rejecting the suggestion . Results    When the doctors accepted the recommendations, the percentage of the next-test international normalized ratio (INR) in the therapeutic range was higher (64.95% vs. 44.64%, RR=2.298, 95%CI 1.173 to 4.499, P=0.014). The logistic regression analysis revealed that accepting the recommendations was an independent predictor for the next-test INR being in the therapeutic range after controlling potentially confounding factors (OR=2.446, 95%CI 1.103 to 5.423, P=0.028). Conclusion    The algorithm of Anticlot Assistant is reasonable and reliable.

Objective To compare patellar ring,Kirschner wire tension band and patellar ring plus Kirschner wire in fixation for treatment of patella fractures.Methods A retrospective analysis was conducted on the 285 patients with patellar fracture who had been treated between September 2009 and January 2016.They were 155 men and 130 women,with an average age of 45.5 years (from 18 to 70 years).Their fractures included 176 transverse,28 longitudinal split and 81 comminuted ones.They were divided into 3 groups according to their different internal fixation methods:patellar ring fixation (98 cases),Kirschner wire tension band (92 cases),patellar ring plus Kirschner wire fixation (95 cases).The 3 groups were compared in terms of operative time,intraoperative bleeding,fracture healing time,knee function by B(o)stman score at the last follow-up and postoperative complications.Results The operative time in the patellar ring group(58.9 ±6.4 min) was significantly shorter than in the Kirschner wire group (71.8 ± 7.8 min) and in the patellar ring plus Kirschner wire group (74.4 ± 8.0 min) (P ＜ 0.05).There were no statistical significant differences between the 3 groups in fracture healing time and intraoperative bleeding (P ＞ 0.05).The good to excellent rate of knee function at the last follow-up in the Kirschner wire tension band group was 100.0％ (92/92),significantly higher than in the patellar ring group (90.8％,89/98) and in the patellar ring plus Kirschner wire group (91.6％,87/95) (P ＜ 0.017).There was no significant difference in postoperative complication rate between the patellar ring fixation group (2.0％,2/98),Kirschner wire tension band fixation group (1.1％,1/92) and the patellar ring plus Kirschner wire group (2.1％,2/95) (P ＞ 0.05).Conclusion Internal fixation with Kirschner wire tension band has definite curative effect on patellar fractures,showing the advantages of less operative invasion,fewer postoperative complications,better functional recovery of the affected knee joint,and lower price over the other 2 internal fixation methods.

ObjectiveTo compare the clinical effect of percutaneous iliosacral screws osteosynthesis (PISO) and open reduction internal reconstruction plate fixation in treating unstable pelvic fractures combined with sacroiliac joint dislocation,and evaluate their safety and practicality.MethodsFrom March 2004 to October 2010,37 patients with vertical unstable pelvic fractures were admitted to our department.Twenty cases were treated with percutaneous sacroiliac screw fixation and 17 cases were performed opened reduction and internal reconstruction plate fixation under C-arm X-ray's guide.The perioperative parameters and postoperative imaging indexes were compared and analyzed.ResultsAll patients were followed up for 6 months to 26 months,with an average of 15 months.There were statistical significances between the PISO group and open reduction internal fixation group in operation time,blood loss,postoperative pain,mean fever time and hospital stay.The two groups showed no significant difference on postoperative X-evaluation of reduction effect.The average healing time was 3.2 months and the difference was not statistically significant between two groups.PISO group had no complications such as infection,bent nails or broken nails.ConclusionThrough compared and analyzed the two groups in treating unstable pelvic fractures,the percutaneous sacroiliac screw fixation has been proved for a kind of ideal minimally invasive surgery method because of locating exactly,less damage and blood loss,milder pain and quicker recovery.But it demands higher operation techniques.Adequate preoperative preparation and postoperative patients' cooperation can reduce complications incidence.The second group of anterior reconstruction plate or T-shape plate to fix vertically unstable pelvic fractures at same time shows a good result of stabilization.

ObjectiveTo study the reasons and mechanism of cardiomyocyte apoptosis in chronic heart failure by using Losartan and to provide a theoretical basis for the treatment of chronic heart failure. Methods The models of chronic heart failure were produced by injecting Adriamycin and Losartan as intervention agents, the expression of apoptotic protein Bax, Bcl-2 and channel protein ERK1, JNK1 and P38MAPK were detected by immunohistochemistry and RT-PCR.Cardiomyocyte apoptosis and myocardial ultrastructure are detected by transmission electron microscopy and TUNEL staining.Results Compared with the model group of heart failure, after Losartan treatment, the ultra structure of myocardial cells were significantly improved, Apoptosis index was decreased significantly (P <0.01), The level of Bax and JNK1 decreased (Bax χ~2=6.6149, P=0.0078; JNK1 q=22.0156,P<0.01). However, the expressions of ERK1 and Bcl-2 were significantly increased (ERK1 q=15.3514,P<0.01;Bcl-2 χ~2=6.81,P=0.0074).Conclusion The effect of Losartan on chronic heart failure is related closely with the pathway of ERK1 and JNK1, and no p38 MAPK pathway.
