The health of women and children serves as the cornerstone of comprehensive public health and represents a crucial barometer for measuring social progress and civilization. It directly impacts family well-being and social harmony. As a national-level guidance center for complex disease diagnosis and treatment, Beijing's critical maternal care center, and the designated consultation hospital for pregnancy complicated by rheumatic immune and endocrine disorders, Peking Union Medical College Hospital bears significant responsibilities in managing complex medical cases and implementing counterpart assistance programs. Confronted with diverse and complicated maternal sources, particularly emergency cases lacking standardized prenatal care, the hospital has established a multi-tiered, whole-process, and comprehensive maternal-infant safety management system. Through implementing high-risk maternal management protocols, optimizing critical care procedures, promoting informatization development, and enhancing multidisciplinary collaboration, Peking Union Medical College Hospital has substantially improved the efficiency of critical maternal care and maternal-infant safety assurance. This paper systematically summarizes the institutional development experience in maternal management and explores potential optimization approaches, aiming to provide valuable references for enhancing maternal-infant safety management systems in domestic healthcare institutions.

Objective:To evaluate the effect of statins combined with PCSK9 inhibitors on coronary artery atherosclerotic plaque, as well as to verify the lipid-lowering effect of the combined therapy.Methods:A computerized search of PubMed, Embase, Web of Science, Cochrane Library, Wanfang, and CNKI databases was conducted to retrieve published literature from inception to December 20, 2022. The English search terms utilized included "PCSK9 inhibitors," "Alirocumab," "Evolocumab," "plaque," "IVUS," and "OCT." The corresponding Chinese search terms were "PCSK9 inhibitors," "plateau," "intravascular ultrasound," and "optical coherence tomography." The literature that examined the effect of statins alone or in combination with PCSK9 inhibitors on coronary atherosclerotic plaques using intravascular ultrasound or optical coherence tomography was identified. The collected data were subsequently processed using Review Manager (Revman) version 5.4.Results:In the final analysis, nine studies involving 1912 patients were included. The analysis results revealed that compared with statins alone, statins combined with PCSK9 inhibitors significantly reduced the percentage of atherosclerotic volume ( MD: -2.08 mm 3, 95% CI: -2.94 to -1.23 mm 3, P < 0.001), accelerated the regression of atherosclerotic volume ( MD: -1.13 mm 3, 95% CI: -1.49 to -0.77 mm 3, P < 0.001), slightly, but not significantly, reduced the overall atherosclerotic volume ( MD: -6.42 mm 3, 95% CI: -14.34-1.51 mm 3, P = 0.110). Nevertheless, the combined therapy contributed to a significant reduction in atherosclerotic volume ( MD: -5.16 mm 3, 95% CI: -7.09 to -3.23 mm 3, P < 0.001) and significantly increased the fiber cap thickness of thin cap plaques ( MD: 8.46 μm, 95% CI: 5.13-11.79 μm, P < 0.001). Additionally, this combined therapy significantly lowered blood lipid levels. Conclusion:The combination of statins and PCSK9 inhibitors can significantly improve the characteristics and phenotype of atherosclerotic plaques and significantly reduce blood lipid levels. For patients with high cardiovascular risk, it is recommended to initiate treatment with statins combined with PCSK9 inhibitors as soon as possible and maintain it for a long time to ensure more benefits.

Objective To evaluate the patient-reported outcome(PRO)of patients with breast cancer who underwent autologous breast reconstruction and implant breast reconstruction.Methods Patients who underwent breast reconstruction in Shanghai Cancer Center,Fudan University from Jan 2020 to Jun 2021 were selected,including 111 patients who underwent autologous breast reconstruction and 108 patients who underwent implant breast reconstruction.Chinese version Breast-Q2.0 scale,breast cancer specificity scale QLQ-BR23 and EORTC quality of life scale QLQ-C30 were used to investigate the PRO of the two groups 18 months after operation.Results The rate of stage Ⅲ breast cancer in the self-weight construction group was higher than that in the implant reconstruction group(64.9%vs.44.4%,P<0.001).The preoperative neoadjuvant therapy and postoperative radiotherapy in the autologous reconstruction group were higher than those in the implant reconstruction group(P<0.001).Postoperative chemotherapy and endocrine therapy in the autologous reconstruction group were lower than those in the implant reconstruction group(P<0.001).The study based on Breast-Q scale showed that the breast satisfaction of autologous reconstruction group was higher than that of implant reconstruction(59.28±17.20 vs.54.94±14.48,P<0.05).The study based on QLQ-BR23 showed that the self-weight construction group was higher than the implant reconstruction group in the field of arm symptoms(20.02±20.80 vs.12.65±16.18,P<0.05).The study based on QLQ-C30 scale showed that there was no significant difference in all functional areas and symptom areas of patients.There was no significant difference in the number and time of social regression between the two groups.Conclusion Breast reconstruction can improve the PRO of breast cancer patients,and oncology factors will affect the choice of breast reconstruction.Patients with autologous breast reconstruction are more satisfied with breast appearance,but upper limb symptoms such as swelling and pain are more obvious than implant reconstruction,which is related to the higher proportion of axillary lymph node dissection in patients with autologous reconstruction.There is no significant difference in quality of life and social regression between the two groups.

Objective:To evaluate the diagnostic performance of the Prostate Imaging Reporting and Data System version 2.1(PI-RADS v2.1)for clinically significant prostate cancer(CSPCa)in the peripheral zone(PZ),transitional zone(TZ)and multiple zones(MZs).Methods:We retrospectively studied the clinical data on 108 patients undergoing multiparametric magnetic resonance imaging(mpMRI)and transperineal prostate biopsy in our hospital from January 2021 to January 2023.Using PI-RADS v2.1,we ex-amined the MR images of the patients with suspected PCa,compared the PI-RADS v2.1 scores with the results of prostate biopsy,and analyzed the correlation of the PI-RADS v2.1 scores with CSPCa.We calculated the area under the receiver operating characteristic(ROC)curve(AUC),and described the diagnostic performance of PI-RADS v2.1 for CSPCa in the PZ,TZ and MZs.Results:Transperineal prostate puncture biopsy was successfully completed in all the patients,which revealed 66(61.11％)cases of CSPCa with Gleason score(GS)7-10.Suspected CSPCa was observed in 45(95.74％)of the 47 PZ lesions,8(47.06％)of the 17 TZ le-sions,and 40(90.91％)of the 44 MZ lesions.The PZ,TZ and MZ lesions diagnosed by PI-RADS v2.1 were significantly correlated with CSPCa(r=0.492,P＜0.001).The AUCs of PI-RADS v2.1 for PZ,TZ and MZs were 0.644,0.732 and 0.811,with specificities of 66.8％,57.6％and 62.1％,and sensitivities of 57.2％,78.4％and 93.2％,respectively.The negative predictive values were 46.5％,85.7％and 79.2％,and the positive predictive values 76.2％,43.4％and 84.8％,respectively.Conclusion:The PI-RADS v2.1 score has a high diagnostic value for CSPCa in the PZ,TZ and MZs,with the best performance for that in the MZs.

Objective To investigate the factors influencing the occurrence of small for gestational age(SGA)at different degrees and provide a basis for early identification of severe SGA cases.Methods Neonatal and maternal prenatal information were retrospectively collected from January 2018 to December 2022 at Peking University People's Hospital.The neonates were divided into three groups:severe SGA group(birth weight below the 3rd percentile for gestational age and sex),mild SGA group(birth weight ≥3rd percentile and＜10th percentile),and non-SGA group(birth weight ≥10th percentile).An ordered multinomial logistic regression model was used to analyze the factors influencing the occurrence of SGA at different degrees.Results A total of 14 821 neonates were included,including 258 cases(1.74％)in the severe SGA group,902 cases(6.09％)in the mild SGA group,and 13 661 cases(92.17％)in the non-SGA group.The proportions of preterm births and stillbirths were higher in the severe SGA group compared to the mild SGA and non-SGA groups(P＜0.0125).The proportion of neonatal asphyxia was higher in both the severe SGA and mild SGA groups compared to the non-SGA group(P＜0.0125).Ordered multinomial logistic regression analysis showed that maternal pre-pregnancy underweight(OR=1.838),maternal pre-pregnancy obesity(OR=3.024),in vitro fertilization-embryo transfer(OR=2.649),preeclampsia(OR=1.743),connective tissue disease during pregnancy(OR=1.795),nuchal cord(OR=1.213),oligohydramnios(OR=1.848),and intrauterine growth restriction(OR=27.691)were all associated with a higher risk of severe SGA(P＜0.05).Maternal parity as a multipara(OR=0.457)was associated with a lower likelihood of severe SGA(P＜0.05).Conclusions Maternal pre-pregnancy underweight,maternal pre-pregnancy obesity,in vitro fertilization-embryo transfer,preeclampsia,connective tissue disease during pregnancy,oligohydramnios,nuchal cord,and intrauterine growth restriction are closely related to the occurrence of more severe SGA.Maternal parity as a multipara acts as a protective factor against the occurrence of severe SGA.[Chinese Journal of Contemporary Pediatrics,2024,26(3):262-268]

The prevalence of Lyme disease in endogenous populations in Urumqi,Xinjiang was investigated.In total,795 serum samples were collected from residents of three townships in the surrounding area of Urumqi City from 2022 to 2023,which included 383 from Lucaogou Town,145 from Shuixigou Town,and,267 from Tori Township.Serum levels of IgG and IgM antibodies were screened with an enzyme linked immunosorbent assay(ELISA)and confirmed by western blot(WB)analysis.Clinical data of WB-positive indi-viduals were collected and comprehensive analysis was con-ducted for case diagnosis.The chi square test was used for statistical analysis of the results and the P＜0.05 was consid-ered statistically significant.In total,110(13.84％)of 795 samples were positive.The positivity rates was higher in females than males[16.26％(73/449)vs.10.69％(37/346),x2=5.076,P=0.024],while there was no significant difference among age groups(x2=2.569,P=0.766).The positivity rates for serum antibodies in Shuixigou Town,Lucaogou Town,and Tuoli Township were 17.98％(48/267),14.48％(21/145),and 10.70％(41/383),respectively,with a significantly higher rate in Tuoli Township than Lucaogou Town(x2=7.041,P=0.008).Of 110 individuals who were initially positive for IgG and IgM antibodies with the ELISA,82(10.31％)were con-firmed positive by WB analysis.In total,20(2.52％)patients were diagnosed with Lyme disease based on clinical manifesta-tions.Lyme disease is epidemic among the population in Urumqi,as the infection rate is higher than the national average.Hence,continued surveillance is recommended for prevention of Lyme disease.

BACKGROUND: Osteopenia has been well documented in adolescent idiopathic scoliosis (AIS). Bone marrow stem cells (BMSCs) are a crucial regulator of bone homeostasis. Our previous study revealed a decreased osteogenic ability of BMSCs in AIS-related osteopenia, but the underlying mechanism of this phenomenon remains unclear. METHODS: A total of 22 AIS patients and 18 age-matched controls were recruited for this study. Anthropometry and bone mass were measured in all participants. Bone marrow blood was collected for BMSC isolation and culture. Osteogenic and adipogenic induction were performed to observe the differences in the differentiation of BMSCs between the AIS-related osteopenia group and the control group. Furthermore, a total RNA was extracted from isolated BMSCs to perform RNA sequencing and subsequent analysis. RESULTS: A lower osteogenic capacity and increased adipogenic capacity of BMSCs in AIS-related osteopenia were revealed. Differences in mRNA expression levels between the AIS-related osteopenia group and the control group were identified, including differences in the expression of LRRC17 , DCLK1 , PCDH7 , TSPAN5 , NHSL2 , and CPT1B . Kyoto Encyclopedia of Genes and Genomes enrichment analyses revealed several biological processes involved in the regulation of autophagy and mitophagy. The Western blotting results of autophagy markers in BMSCs suggested impaired autophagic activity in BMSCs in the AIS-related osteopenia group. CONCLUSION Our study revealed that BMSCs from AIS-related osteopenia patients have lower autophagic activity, which may be related to the lower osteogenic capacity and higher adipogenic capacity of BMSCs and consequently lead to the lower bone mass in AIS patients.

Objective: To compare the effects and safety of dydrogesterone (DG) and medroxyprogesterone acetate (MPA) on the treatment in patients with endometrial hyperplasia without atypia (EH). Methods: This was a single-center, open-label, prospective non-inferior randomized controlled phase Ⅲ trial. From February 2019 to November 2021, patients with EH admitted to the Obstetrics and Gynecology Hospital of Fudan University were recruited. Enrolled patients were stratified according to the pathological types of simple hyperplasia (SH) or complex hyperplasia (CH), and were randomised to receive MPA or DG. Untill May 14, 2022, the median follow-up time after complete response (CR) was 9.3 months (1.1-17.2 months). The primary endpoint was the 6-month CR rate (6m-CR rate). The secondary endpoints included the 3-month CR rate (3m-CR rate), adverse events rate, recurrence rate, and pregnancy rate in one year after CR. Results: (1) A total of 292 patients with EH were enrolled in the study with the median age of 39 years (31-45 years). A total of 135 SH patients were randomly assigned to MPA group (n=67) and DG group (n=68), and 157 CH patients were randomly assigned to MPA group (n=79) and DG group (n=78). (2) Among 292 patients, 205 patients enrolled into the primary endpoint analysis, including 92 SH patients and 113 CH patients, with 100 patients in MPA group and 105 in DG group, respectively. The 6m-CR rate of MPA group and DG group were 90.0% (90/100) and 88.6% (93/105) respectively, and there were no statistical significance (χ²=0.11, P=0.741), with the rate difference (RD) was -1.4% (95%CI:-9.9%-7.0%). Stratified by the pathology types, the 6m-CR rate of SH patients was 93.5% (86/92), and MPA group and DG group were respectively 91.1% (41/45) and 95.7% (45/47); and the 6m-CR rate of CH patients was 85.8% (97/113), and MPA group and DG group were 89.1% (49/55) and 82.8% (48/58) respectively. The 6m-CR rates of the two treatments had no statistical significance either (all P>0.05). A total of 194 EH patients enrolled into the secondary endpoint analysis, including 88 SH patients and 106 CH patients, and 96 patients in MPA group and 98 in DG group, respectively. The 3m-CR rate of SH patients were 87.5% (77/88), while the 3m-CR rates of MPA group and DG group were 90.7% (39/43) and 84.4% (38/45), respectively; the 3m-CR rate of CH patients was 66.0% (70/106), and MPA group and DG group had the same 3m-CR rate of 66.0% (35/53). No statistical significance was found between the two treatments both in SH and CH patients (all P>0.05). (3) The incidence of adverse events between MPA group and DG group had no statistical significance (P>0.05). (4) A total of 93 SH patients achieved CR, and the cumulative recurrence rate in one year after CR were 5.9% and 0 in MPA group and DG group, respectively. While 112 CH patients achieved CR, and the cumulative recurrence rate in one year after CR were 8.8% and 6.5% in MPA group and DG group, respectively. There were no statistical significance between two treatment groups (all P>0.05). Among the 93 SH patients, 10 patients had family planning but no pregnancy happened during the follow-up period. Among the 112 CH patients, 21 were actively preparing for pregnancy, and the pregnancy rate and live-birth rate in one year after CR in MPA group were 7/9 and 2/7, while in DG group were respectively 4/12 and 2/4, and there were no statistical significance in pregnancy rate and live-birth rate between the two treatment groups (all P>0.05). Conclusions: Compared with MPA, DG is of good efficacy and safety in treating EH. DG is a favorable alternative treatment for EH patients.

Objective: To investigate the clinical characteristics of colon complications in patients with necrotizing pancreatitis(NP). Methods: The clinical data of 403 patients with NP admitted to the Department of General Surgery,Xuanwu Hospital, Capital Medical University from January 2014 to December 2021 were retrospectively analyzed. There were 273 males and 130 females,aged (49.4±15.4) years(range: 18 to 90 years). Among them,there were 199 cases of biliary pancreatitis,110 cases of hyperlipidemic pancreatitis,and 94 cases of pancreatitis caused by other causes. A multidisciplinary diagnosis and treatment model was used to diagnose and treat patients. Depending on whether the patients had colon complications,they were divided into colon complications group and noncolon complications group. Patients with colon complications were treated with anti-infection therapy,parental nutritional support,keeping the drainage tube unobstructed,and terminal ileostomy. The clinical results of the two groups were compared and analyzed using a 1∶1 propensity score match(PSM) method. The t test,χ² test, or rank-sum test was used to analyze data between groups,respectively. Results: The incidence of colon complications was 13.2%(53/403),including 15 cases of colon obstruction,23 cases of colon fistula,and 21 cases of colon hemorrhage. After PSM,the baseline and clinical characteristics at admission of the two groups of patients were comparable (all P>0.05). In terms of clinical outcome,compared to patients with NP without colon complications,the number of patients with colon complications who received minimally invasive intervention(88.7%(47/53) vs. 69.8%(37/53),χ²=5.736,P=0.030),the number of minimally invasive interventions (M(IQR))(2(2) vs. 1(1), Z=4.638,P=0.034),the number of patients with multiple organ failure(45.3%(24/53) vs. 32.1%(17/53),χ²=4.826,P=0.041),and the number of extrapancreatic infections(79.2%(42/53) vs. 60.4%(32/53),χ²=4.476,P=0.034) increased significantly. The time required for enteral nutrition support(8(30)days vs. 2(10) days, Z=-3.048, P=0.002), parental nutritional support(32(37)days vs. 17(19)days, Z=-2.592, P=0.009),the length of stay in the ICU(24(51)days vs. 18(31)days, Z=-2.268, P=0.002),and the total length of stay (43(52)days vs. 30(40)days, Z=-2.589, P=0.013) were also significantly prolonged. However,mortality rates in the two groups were similar(37.7%(20/53) vs. 34.0%(18/53),χ²=0.164,P=0.840). Conclusions: Colonic complications in NP patients are not rare,which can lead to prolonged hospitalization and increased surgical intervention. Active surgical intervention can help improve the prognosis of these patients.
