Perinatal depression is a psychological disorder that occurs during pregnancy and within one year of delivery, which can seriously affect the physical and mental health of pregnant and postpartum women, as well as the cognitive and behavioral abilities of offspring, with potential multigenerational effects. Therefore, it is important to identify its potential modifiable risk factors. Phthalic acid esters (PAEs), as common environmental endocrine disruptors, can affect maternal estrogen through multiple mechanisms and are important potential modifiable risk factors for developing maternal perinatal depression. At present, studies on the correlation between PAEs and perinatal depression are still very limited, and the mechanisms by which PAEs affect perinatal depression have not been clarified. Based on existing epidemiological and toxicological studies at home and abroad, the article briefly introduced the characteristics of multiple pathways, high doses, and long-term exposure to maternal PAEs, focused on reviewing the current status of epidemiological studies, pointed out the possible associations between some specific PAEs exposure and elevated risk of perinatal depression. It also summarized the potential roles of hormone-neurotransmitter pathway, inflammation mediation, gene regulation, and other possible mechanisms in the association between exposure to PAEs and perinatal depression. The article concluded with a look at how future research on the association between exposure to PAEs and perinatal depression can be scientifically validated, with a view to providing more high-quality evidence for the scientific prevention of the onset and progression of maternal depressive symptoms.

Objective To investigate the expression of circular RNA(Circ RNAS)Actinin α 4(ACTN4)and platelet thrombin protein 1(THBS1)in intrahepatic cholangiocarcinoma(ICC)and their relationship with clinicopathological characteristics and prognosis,and provide reference for clinical diagnosis and treatment.Method A retrospective analysis was conducted on 84 ICC patients diagnosed and treated in the Second Affiliated Hospital of Xian Jiaotong University from May 2017 to June 2020.The expressions of CircACTN4 mRNA,THBS1 mRNA and protein were detected by real-time fluorescent quantitative PCR and immunohistochemistry.Pearson correlation analysis was used to analyze the correlation between CircACTN4 mRNA and THBS1 mRNA in ICC cancer tissue.The prognostic differences of ICC patients with different CircACTN4 mRNA and THBS1 mRNA expressions were compared by the Kaplan-Meier method(log rank test).COX regression analysis was performed to identify prognostic factors in ICC patients.The prognostic value of CircACTN4 mRNA and THBS1 mRNA in evaluating the risk of death in ICC patients was assessed by receiver operating characteristic(ROC)curve analysis.Results The expression of CircACTN4 mRNA in ICC tissues(3.14±0.42)was higher than that in adjacent tissues(0.76±0.25),with significant difference(t=44.094,P＜0.001).The positive rates of THBS1 mRNA(2.82±0.36)and protein positive rate(92.86％)in ICC tissues were higher than those in adjacent tissues(0.81±0.24,7.14％),and the differences were statistically significant(t/x2=42.068,123.429,all P＜0.001).CircACTN4 mRNA was positively correlated with THBS1 mRNA in ICC cancer tissue(r=0.669,P＜0.001).The expressions of CircACTN4 mRNA,THBS1 mRNA in ICC cancer tissues with TNM stage Ⅲ,low differentiation,and lymph node metastasis were higher than those in TNM stage Ⅰ～Ⅱ,high differentiation,and non-lymph node metastasis cancer tissues,and the differences were statistically significant(x2=7.949,9.164,12.207;23.270,18.625,19.828,all P＜0.001).The 3-year cumulative survival rates of the high expression group of CircACTN4 mRNA and THBS1 mRNA were lower than those of the low expression group of CircACTN4 mRNA(25.00％vs 56.82％)and THBS1 mRNA(19.51％vs 62.79％),and the differences were statistically significant(Log rank x2=13.601,24.310,all P＜0.001).CircACTN4 mRNA(OR=1.839,95％CI:1.228～2.753),THBS1 mRNA(OR=1.744,95％CI:1.245～2.443),lymph node metastasis(OR=1.925,95％CI:1.316～2.816),TNM staging(OR=1.613,95％CI:1.223～2.126),and tumor differentiation(OR=1.510,95％CI:1.205～1.892)were independent factors affecting the prognosis of ICC.The area under the curve of the combination detection of circACTN4 and THBS1 mRNA on the prognosis of death in patients with ICC was 0.868,which was greater than that of the single index(0.812 and 0.784),with significant differences(Z=3.348,3.847,all P＜0.001).Conclusion The expressions of CircACTN4 mRNA and THBS1 mRNA were increased in ICC,and they were associated with TNM stage,differentiation,and lymph node metastasis.These markers may serve as novel indicators to evaluate the poor prognosis of ICC patients.

After laparoscopic-assisted Soave procedure, the child had normal bowel movements, and no surgery-related compli-cations occurred during the follow-up period.The child′s motor development improved after rehabilitation treatment.According to literature review, 2 female cases show similar clinical manifestations to this girl, but the genotypes were different.This patient expands the clinical phenotype of ZEB2 gene pathogenicity.

Objective:To investigate the predictive value of neutrophil-lymphocyte ratio (NLR) for Trousseau’s syndrome (TS) in patients with acute multiple cerebral infarctions (AMCI).Methods:The patients with AMCI in Suzhou Kowloon Hospital, Shanghai Jiaotong University School of Medicine from July 2013 to March 2022 were retrospectively enrolled. The demographic and baseline clinical data of patients with TS and those without TS were compared. Multivariate logistic regression analysis was used to determine the independent influencing factors of TS-AMCI, and receiver operating characteristic (ROC) curve was used to evaluate the predictive value of NLR for TS-AMCI. Results:A total of 59 patients with AMCI were enrolled, including 43 males and 16 females, aged 64.9±14.0 years. There were 16 patients in the TS-AMCI group and 43 in the non-TS-AMCI group. The proportions of patients with diabetes mellitus, hypertension and previous stroke or transient ischemic attack in the TS-AMCI group were significantly lower than those in the non-TS-AMCI group (all P<0.05), while the proportion of patients with ischemic heart disease were significantly higher than that in the non-TS-AMCI group ( P<0.05). The proportion of patients with bilateral infarction in the TS-AMCI group was significantly higher than that in the non-TS-AMCI group ( P<0.001). The D-dimer, NLR, white blood cell count, neutrophil count, monocyte count, percentage of neutrophils, total cholesterol and low-density lipoprotein cholesterol in the TS-AMCI group were significantly higher than those in the non-TS-AMCI group (all P<0.001), while the lymphocyte count, lymphocyte percentage, red blood cell count, hemoglobin and hematocrit were significantly lower than those in the non-TS-AMCI group (all P<0.001). Multivariate logistic regression analysis showed that high NLR was an independent predictor of TS-AMCI (odds ratio [ OR] 2.897, 95% confidence interval [ CI] 1.270-6.527; P=0.011), while high hemoglobin was independently negatively correlated with TS-AMCI ( OR 0.839, 95% CI 0.723-0.975; P=0.022). ROC curve analysis showed that the area under the curve of NLR for predicting TS-AMCI was 0.929 (95% CI 0.831-0.979; P<0.001). When the NLR cutoff value was 4.01, the corresponding Youden index was 0.744. At this time, the sensitivity and specificity were 100% and 74.42% respectively. Conclusion:NLR has high predictive value for TS-AMCI.

Objective:To compare the accuracy of two methods in reducing leg length discrepancy(LLD)during hip hemiarthroplasty.Methods:We retrospectively analyzed 89 patients of hip hemiarthroplasty who suffered from femoral neck fracture.There were 47 patients in the new method group(NM), and 42 patients in the traditional method group(traditional method, TM)which comparing the position of the greater trochanter tip and the center of the femoral head.In the NM group, the distance from the center of femoral head to the lesser trochanter(L)and the diameter of femoral head(D)of the healthy side hip were measured on preoperative anteroposterior pelvic X-ray film, and the ratio(R)of D to L was calculated.During operation, the diameter of the femoral head(d)was measured with a caliper, and the distance should be obtained from the center of the femoral head prosthesis to the lesser trochanter according to the ratio R of the healthy side.The difference of postoperative LLD between the two groups and the incidences of |LLD| in each range were compared.Results:In the NM group, the maximum LLD was 11.10 mm and the minimum LLD was -4.0 mm, with an average of(4.4±3.2)mm, 80.9%(38/47)| LLD | < 6 mm, 93.6%(44/47)| LLD | < 10 mm, 6.4%(3/47)| LLD | ≥ 10 mm.In the TM group, the maximum LLD was 13.2 mm and the minimum LLD was -8.3 mm, with an average of (6.2±5.1)mm, 42.9%(18/42)|LLD|<6 mm, 69.0%(29/42)|LLD| <10 mm, 31.0%(13/42)|LLD|≥10mm.The differences of patients of the mean postoperative LLD and the incidences of |LLD| in each range between two the groups were statistically significant( t=-2.036、 χ2=14.629, P=0.046、0.001). Conclusions:The new method is simple, convenient, more accurate and can obtain a more satisfactory LLD compared with the traditional method which refers to the relative position of the great trochanter tip and the center of the femoral head.

Histone lysine specific demethylase 1 (LSD1) has been recognized as an important modulator in post-translational process in epigenetics. Dysregulation of LSD1 has been implicated in the development of various cancers. Herein, we report the discovery of the hit compound (IC = 3.93 μmol/L) and further medicinal chemistry efforts, leading to the generation of compound (IC = 49 nmol/L, and = 16 nmol/L), which inhibited LSD1 reversibly and competitively with H3K4me2, and was selective to LSD1 over MAO-A/B. Docking studies were performed to rationalize the potency of compound . Compound also showed strong antiproliferative activity against four leukemia cell lines (OCL-AML3, K562, THP-1 and U937) as well as the lymphoma cell line Raji with the IC values of 1.79, 1.30, 0.45, 1.22 and 1.40 μmol/L, respectively. In THP-1 cell line, significantly inhibited colony formation and caused remarkable morphological changes. Compound induced expression of CD86 and CD11b in THP-1 cells, confirming its cellular activity and ability of inducing differentiation. The findings further indicate that targeting LSD1 is a promising strategy for AML treatment, the triazole-fused pyrimidine derivatives are new scaffolds for the development of LSD1/KDM1A inhibitors.

Objective: To analyze the risk factors of cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. Methods: 530 patients with esophageal cancer underwent thoracoscopic-lapacoscopic esophagectomy at the Cancer Hospital, Chinese Academy of Medical Sciences from Jan 2011 to Dec 2015. The demographic, surgical and clinical data of patients were retrospectively analyzed. Multivariate logistic regression was used to evaluate risk factors of cervical anastomotic leakage in these patients. Results: A total of 530 patients undergoing thoracoscopic-lapacoscopic esophagectomy were enrolled in this study. There were 421 males and 109 females. The mean age was (59.40±8.08) years old, and 91 patients with cervical anastomotic leakage. Sigle factor analysis revealed that the risk grading by American Society of Aneshesiologists, previous history of chest surgery, respiratory comorbidity, diffusion capacity for carbon monoxide of the lung, operation time, anastomosis, average days of postoperative hospitalization, death within 30 days after surgery, respiratory complications, pleural effusion or empyema, and poor healing of the incision were statistically associated with cervical anastomotic leakage (all P<0.05). Multivariate analysis showed that previous history of chest surgery, hepatic insufficiency, manual anastomosis, prolonged postoperative hospitalization, and poor healing of the incision were independent risk factors for cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy (all P<0.05). Conclusions Previous history of chest surgery, hepatic insufficiency, poor healing of the incision, manual anastomosis and prolonged postoperative hospitalization were significantly associated with cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. It′s important to strengthen perioperative nursing and surgical techniques to prevent anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.
