Objective:To carry out carrier screening among people of childbearing age, detect the pathogenic genes of monogenic genetic diseases and analyze the carrier status of pathogenic variants, so as to provide fertility guidance and intervention measures for high-risk families.Methods:From August 2022 to August 2023, 1 533 families of childbearing age who met the criteria were recruited in the Chinese PLA General Hospital, including a total of 3 044 subjects. According to the standard enrollment procedure, 223 genes (197 autosomal recessive genes and 26 X-linked genes) of the subjects were tested. According to the screening results, genetic counseling and fertility guidance were provided to the subjects. Invasive prenatal diagnosis was performed for high-risk couples (both couples being carriers of the same autosomal recessive disease gene or the woman was a carrier of X-linked disease gene), and their pregnancy pattern, outcome and offspring phenotype were followed up.Results:(1) A total of 3 044 cases from 1 511 couples and women of childbearing age from 22 families were included for carrier screening. Totally 1 503 families chose simultaneous screening and 30 families chose sequential screening out of the 1 533 families. Among the 3 044 subjects, 1 603 individuals carried at least one pathogenic or likely pathogenic variant, and the overall carrier rate was 52.66% (1 603/3 044). A total of 2 292 pathogenic or likely pathogenic variants were detected, and 0.75 variants (2 292/3 044) were detected per capita. (2) The three genes with the highest carrier rates were GJB2 (8.67%, 264/3 044), CYP21A2 (3.19%, 97/3 044) and PAH (3.09%, 94/3 044). There were 32 genes with a carrier rate ≥1/200, 17 genes with a carrier rate ≥1/100, and 7 genes with a carrier rate ≥1/50. (3) Thirty-eight high-risk families were identified. After excluding G6PD gene mutation, there were 33 high-risk families, of which 25 couples were carriers of the same autosomal recessive gene, 9 women were carriers of X-linked gene, and 1 family was double high-risk couple with both autosomal recessive and X-linked gene. After further excluding the GJB2 c.109G>A mutation, 21 high-risk families were identified. Preimplantation genetic testing for monogenic disease was performed in 12 families after genetic counseling. Prenatal diagnosis was completed in 4 out of 5 high-risk families who conceived naturally. Two fetuses carried the parental variants and terminated the pregnancy, one fetus did not carry the parental variants but was induced due to trisomy 21 syndrome, and one fetus was a carrier of congenital disorders of glycosylation type 1a.Conclusions:Carrier screening effectively identifies high-risk genetic disease families and provides reproductive guidance to prevent the birth of affected children. However, establishing multidisciplinary team is essential for managing complex cases. Implementation should prioritize prenatal institutions with genetic counseling or diagnostic expertise for monogenic disorders or established referral networks.

Objective:To develop a novel, flexible, dual-arm, master-slave digestive endoscopic minimally invasive surgical robot system named dual-arm robotic endoscopic assistant for minimally invasive surgery (DREAMS) and to evaluate its feasibility for endoscopic submucosal dissection (ESD) by using ex vivo porcine stomachs.Methods:A novel endoscopic robot (DREAMS) system was developed which was composed of a flexible two-channel endoscope, two flexible robotic manipulators, a master controller, a robotic arm, and a control system. A total of 10 artificial round-like lesions with diameters ranging from 15 to 25 mm were created (5 in gastric antrum and 5 in gastric body) by using fresh peeled stomach of healthy pigs as the model. Submucosal dissection was performed with the assistance of the DREAMS system by two operators. The main outcome was submucosal dissection speed, and the secondary outcomes included muscular injury rate, perforation rate, and grasping efficiency of the robot.Results:All 10 lesions were successfully dissected en bloc by using the DREAMS system. The diameter of the artificial lesions was 22.34±2.39 mm, dissection time was 15.00±8.90 min, submucosal dissection speed was 141.79±79.12 mm 2/min, and the number of tractions required by each ESD was 4.2 times. Muscular injury occurred in 4/10 cases of ESD. No perforation occurred. Conclusion:The initial animal experiment shows the DREAMS system is safe and effective.

Objective:To investigate COVID-19 vaccination status and relevant adverse reactions in patients with psoriasis treated with biological agents, and to explore the effect of COVID-19 vaccination on psoriatic lesions.Methods:Clinical data were collected from 572 psoriasis patients aged 18 - 60 years, who were registered in the management system of psoriasis patients treated with biological agents in the University of Hong Kong-Shenzhen Hospital from May 2019 to June 2021. The COVID-19 vaccination status was investigated by telephone interviews, and the vaccination-related information was obtained by fixed healthcare workers during a fixed time period according to a predesigned questionnaire. Measurement data were compared between two groups by using t test, and enumeration data were compared by using chi-square test or Fisher′s exact test. Results:The COVID-19 vaccination coverage rate was 43.13% (226 cases) among the 524 patients who completed the telephone interview, and was significantly lower in the biological agent treatment group (30.79%, 105/341) than in the traditional drug treatment group (66.12%, 121/183; χ2 = 60.60, P < 0.001) . The main reason for not being vaccinated was patients′ fear of vaccine safety (49.66%, 148/298) , followed by doctors′ not recommending (26.51%, 79/298) . In the biological agent treatment group after vaccination, the exacerbation of psoriatic lesions was more common in patients receiving prolonged-interval treatment (42.86%, 6/14) compared with those receiving regular treatment (4.40%, 4/91; Fisher′s exact test, P < 0.001) . Skin lesions were severely aggravated in two patients after COVID-19 vaccination, who ever experienced allergic reactions and whose skin lesions did not completely subside after the treatment with biological agents. Conclusions:The COVID-19 vaccination coverage rate was relatively low in the psoriasis patients treated with biological agents, and no serious adverse reaction was observed after vaccination. Prolonged-interval treatment due to COVID-19 vaccination ran the risk of exacerbation of skin lesions.

Objective:To explore the influence of interpregnancy interval (IPI) on pregnancy complications in multiparas.Methods:This was a retrospective cohort study involving 7 669 singleton parturients who delivered at ≥28 gestational weeks in the Affiliated Hospital of Southwest Medical University between December 2015 and December 2020 and had given birth in the third trimester before. Clinical data were collected, including the baseline characteristics, pregnancy complications, gestational weeks at delivery, and neonatal birth weight. According to the IPI, these women were divided into five groups: <12 months ( n=350), 12-<24 months ( n=945), 24-<60 months ( n=2 544), 60-<120 months ( n=2 478), and ≥120 months ( n=1 352). Based on the recommendation of the World Health Organization, pregnant women with an IPI of 24-<60 months were the control group. A multivariate logistic model was used to adjust for confounders and calculate the risks of pregnancy complications, including gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP). The influences of maternal age and previous delivery mode on the associations between IPI and maternal complications were analyzed. Analysis of variance (ANOVA), Chi-square test, and Cochran-Mantel-Haenszel Chi-square test were used for statistical analysis. Results:Compared with the control group, the incidence of GDM and HDP increased in the 60-<120 months group ( OR=1.23, 95% CI: 1.01-1.48 and OR=1.47, 95% CI: 1.13-1.92) and ≥120 months group ( OR=1.37, 95% CI:1.07-1.78 and OR=1.92, 95% CI: 1.39-2.64); the risks of uterine rupture/postpartum hemorrhage and placental abruption increased in the <12 months group ( OR=1.54, 95% CI: 1.01-2.34) and 12-<24 months group ( OR=2.38 95% CI: 1.13-5.02), respectively. In the 60-<120 months group, the risk of GDM increased only in non-elderly women (adjusted OR=1.71, 95% CI: 1.36-2.14), so did the risks of GDM and HDP in the ≥120 months group (adjusted OR=3.11, 95% CI: 2.10-4.62 and adjusted OR=1.81, 95% CI: 1.12-2.91). Among women who had undergone a previous cesarean section, the risk of GDM increased in the ≥120 months group (adjusted OR=1.35, 95% CI: 1.00-1.81). In the 60-<120 months group and ≥120 months group, the risk of HDP increased in postpartum women (adjusted OR=1.79, 95% CI: 1.08-2.95 and adjusted OR=3.32, 95% CI: 1.91-5.77). Conclusion:IPI≥60 months is a risk factor for GDM and HDP, and the associations between IPI and maternal complications are influenced by maternal age.

Objective:This study aimed to investigate the risk features of postoperative tumor recurrence of medullary thyroid carcinoma.Methods:One hundred and seventy two patients with medullary thyroid carcinoma diagnosed at Tianjin Cancer Hospital between Jan 2010 and Jan 2018 were enrolled in this study. Based on the follow-up results, patients were divided into tumor recurrence and non-tumor recurrence group. US features,clinicopathological characteristics and somatic RET mutations were evaluated between the two groups. The cut-off values of pre-and post-operative serum calcitonin were calculated by ROC curve.Univariate and multivariate analysis were adopted between the two groups to determine independent risk factors for tumor recurrence of MTC.Tumor-free survival was determined by Kaplan-Meier analysis.Results:Univariate analysis showed that preoperative serum calcitonin≥1 367 pg/ml ( χ2=18.909, P=0.000), postoperative serum calcitonin ≥61 pg/ml ( χ2=72.278, P=0.000), mulifocality ( χ2=11.787, P=0.001),lesions in both lobes ( χ2=10.452, P=0.003), extrathyroidal invasion ( χ2=14.511, P=0.000), T3+T4-staging ( χ2=11.920, P=0.001)、TNMⅢ+Ⅳ-staging ( χ2=18.915, P=0.000), ACR TI-RADS 5 ( χ2=7.162, P=0.006) and RET mutation ( χ2=10.937, P=0.001) were significantly related to tumor recurrence of medullary thyroid carcinoma. Multivariate analysis demonstrated that postoperative serum calcitonin≥61 pg/ml ( OR=22.323, 95%CI: 6.370-78.236) and RET mutation ( OR=4.054, 95%CI: 1.354-12.139) were the independent factors related to tumor recurrence of medullary thyroid carcinoma.The survival curves of MTC patients showed a significantly lower percentage of surviving patients in the group with postoperative serum calcitonin ≥61 pg/ml ( P=0.000) or RET mutations ( P=0.001). Conclusions:Postoperative serum calcitonin ≥61 pg/ml and oncogenic RET mutation were the independent risk factors for tumor recurrence of MTC.Patients with postoperative serum calcitonin ≥61 pg/ml or a RET mutation tended to have a shorter tumor-free survival.
