Objective To investigate the predictive value of labor progress angle (AOP), fetal head descent distance (HPD) and their change rates in the outcome of vaginal trial of cesarean scar uterus. Methods A total of 170 pregnant women who underwent vaginal trial production of scar uterus after cesarean section were selected as study subjects, and were divided into successful group and failed group based on the trial production outcomes. Advanced oxidation processes (AOP) and head-perineum distance (HPD) were measured by ultrasound during the active phase of the first stage of labor when the cervix dilated to 4 cm and at 1 hour after the cervix dilated to 4 cm, respectively. The AOP change rate and HPD change rate after 1 hour of progress were calculated. The receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of AOP, HPD and their change rates in the outcome of vaginal trial production of scar uterus after cesarean section. Delong test was used to compare the differences in area under curves (AUCs). Results Among 170 pregnant women with scarred uterus after cesarean section who were pregnant again, 139 cases (success group) were succeed in transvaginal delivery, while 31 cases failed trial delivery, and transferred to cesarean section (failure group). The AOP of the successful group was significantly larger than that of the failed group when the cervix was opened to 4 cm, and the HPD was significantly shorter than that of the failure group (P < 0.05). The AOP change rate and the change rate of HPD of the successful group were significantly higher than that of the failed group when the cervix dilated to 4 cm and at 1 hour (P < 0.05). The AUC of AOP and HPD in predicting the outcome of vaginal trial delivery of scar uterus after cesarean section were 0.846 and 0.812 respectively, and AUC predicted jointly by AOP and HPD showed no significant differences compared with AUC predicted separately (P>0.05). The AUC of the change rate of AOP and HPD in predicting the outcome of vaginal trial delivery of scarred uterus after cesarean section was 0.899 and 0.852 respectively, and the combined prediction of AOP change rate and HPD change rate had a higher AUC value than the AUC predicted separately. Its AUC value was higher than that of AOP combined with HPD (P < 0.05). Conclusion The AOP, HPD and their change rates when the uterine orifice expands to 4 cm in the active phase of the first stage of labor have predictive value for the outcome of vaginal trial production of scarred uterus after cesarean section.

Objective:To assess the changes in corneal endothelial cell density (CD) and morphology in patients with different stages of keratoconus.Methods:A cross-sectional study was conducted.One hundred and nineteen patients (199 eyes) with keratoconus who were treated in the Eye Hospital of Shandong First Medical University were included from March 2018 to October 2021.The 199 eyes were classified into stage Ⅰ (111 eyes of 58 cases), stage Ⅱ (41 eyes of 30 cases), stage Ⅲ (47 eyes of 31 cases) keratoconus groups according to the Amsler-Krumeich classification.In the same period, 25 age- and sex-matched healthy subjects (50 eyes) were enrolled as a normal control group.Corneal topography and anterior segment parameters such as keratometry (K), central corneal thickness (CCT), thinnest corneal thickness (TCT), anterior chamber depth (ACD), corneal diameter and corneal volume were obtained by Pentacam 3-dimensional anterior segment imaging and analysis system.The corneal endothelial CD, percentage of hexagonal cells (6A), average cell area (AVE), maximum cell area (MAX), minimum cell area (MIN), cell area standard deviation (SD) and cell area coefficient of variation (CV) in the central area were evaluated by non-contact specular microscopy.The correlation between corneal endothelial CD, morphological parameters and corneal topographic parameters was analyzed by Spearman rank correlation.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Shandong Eye Hospital (No.SDSYKYY201803). All patients were informed of the purpose and methods of the study and written informed consent was obtained before any medical examination.Results:The CD of the normal control group and stage Ⅰ, Ⅱ, Ⅲ keratoconus groups was 2 941(2 809, 3 072), 2 825(2 667, 3 030), 2 747(2 475, 2 903) and 2 370(2 142, 2 525) cells/mm 2, respectively.With the progression of keratoconus, CD decreased gradually, and there was a significant difference in CD among the four groups ( H=94.862, P<0.001). There were significant differences in CV and 6A among the four groups ( H=45.018, 20.421; both at P<0.001). CV was significantly higher in stage Ⅲ keratoconus group than that of the normal control group and stage Ⅰ and Ⅱ keratoconus groups and 6A was significantly lower in stage Ⅲ keratoconus group than that of the normal control group and stage Ⅰ keratoconus group (all at P<0.05). With the progression of keratoconus, MAX, MIN, AVE and SD increased gradually, and there were significant differences in MAX, MIN, AVE and SD among the four groups ( H=37.905, 32.437, 110.182, 72.941; all at P<0.001). MAX and MIN in stage Ⅲ keratoconus group were significantly higher than those in stage Ⅰ keratoconus groups and normal control group (all at P<0.05). AVE and SD in stage Ⅲ keratoconus group were significantly higher than those in normal control group and stage Ⅰ and Ⅱ keratoconus groups (all at P<0.05). In patients with keratoconus, CD was moderately positively correlated with CCT ( rs=0.47, P<0.001) and TCT ( rs=0.53, P<0.001), and was moderately negatively correlated with mean keratometry (Km) ( rs=-0.59, P<0.001).6A was weakly positively correlated with CCT ( rs=0.18, P=0.01) and TCT ( rs=0.22, P=0.002), and was weakly negatively correlated with Km ( rs=-0.32, P<0.001). CV was weakly negatively correlated with CCT ( rs=-0.35, P<0.001) and TCT ( rs=-0.37, P<0.001), and was moderately positively correlated with Km ( rs=0.48, P<0.001). There was no correlation between CD, CV, 6A and ACD, or corneal volume. Conclusions:As the keratoconus progresses, the cornea protrudes and becomes thinner with CD and 6A decreasing while CV increasing.Corneal topographic parameters are related to the density and morphology of corneal endothelial cells.

Objective:To evaluate the efficacy and safety of peroral endoscopic myotomy (POEM) in achalasia of cardia (AC) patients with the long course.Methods:A total of 159 AC patients who received POEM from January 2015 to March 2022 in the First Affiliated Hospital of Soochow University were divided into the long course group (≥10 years) and the non-long course group (<10 years). The baseline information, POEM procedure and postoperative recurrence were compared and the differences between the recurrent patients and non-recurrent patients in the long course group were explored.Results:The age (57.09±14.30 years VS 42.08±15.68 years, t=5.569, P<0.001), the rate of treatment history [28.9% (13/45) VS 9.6% (11/114), χ2=9.319, P=0.020], the proportion of Henderson grade Ⅲ esophagus [17.8% (8/45) VS 6.1% (7/114), χ2=7.020, P=0.030] in the long course group were significantly higher than those in the non-long course group. The recurrence rate in the long course group was significantly higher than that in the non-long course group [33.3% (15/45) VS 14.9% (17/114), χ2=6.811, P=0.009]. In the long course group, the age (62.50 ± 16.94 years VS 53.77 ± 12.95 years, t=-2.121, P=0.040), and the rate of treatment history [53.3% (8/15) VS 16.7% (5/30), χ2=6.544, P=0.016] in the recurrent patients were higher than those in the non-recurrent patients. Conclusion:POEM is safe and effective for long-course AC patients. In patients with the long course, the aged patients with previous treatment are more likely to relapse.

Objective:To evaluate the safety and efficacy of carotid artery stenting (CAS) in the treatment of non-circumferential severe calcification using the distal embolic protection device.Methods:Clinical data of patients with severe calcification lesions in cervical carotid artery treated by CAS from Jan 2018 to Dec 2020 at our center was analyzed retrospectively.Results:226 consecutively admitted patients of cervical carotid artery stenosis and non-circumferential severe calcification (CR>270°) underwent CAS using the distal embolic protection device. The technical success rate was 90.26%. No death or myocardial infarction occurred during the perioperative period. Two patients had ipsilateral hemiparesis ischemic stroke during post-dilatation. The incidence of perioperative bradycardia/hypotension was 25.34%. Patients were followed up for 6-36 months, with median follow-up period of 17.3 months. The incidence of mild or moderate in-stent restenosis (<70%) was 16.59%, and the incidence of severe in-stent restenosis or occlusion (>70%) was 3.22%.Conclusions:For carotid artery stenosis with non-circumferential severe calcification in high risk for CEA patients, carotid artery stenting is safe and effective with the aggressive pre-dilation strategies, strict stent selections and implantation standards. The incidence of perioperative death, myocardial infarction or ipsilateral hemiparesis ischemic stroke was low. The patency rate of the carotid stent in the calcification lesion is satisfactory during the mid-term follow-up.

Exploring the genetic basis of human infertility is currently under intensive investigation.However,only a handful of genes have been validated in animal models as disease-causing genes in infertile men.Thus,to better understand the genetic basis of human spermatogenesis and bridge the knowledge gap between humans and other animal species,we construct the FertilityOnline,a data-base integrating the literature-curated functional genes during spermatogenesis into an existing sper-matogenic database,SpermatogenesisOnline 1.0.Additional features,including the functional annotation and genetic variants of human genes,are also incorporated into FertilityOnline.By searching this database,users can browse the functional genes involved in spermatogenesis and instantly narrow down the number of candidates of genetic mutations underlying male infertility in a user-friendly web interface.Clinical application of this database was exampled by the identifi-cation of novel causative mutations in synaptonemal complex central element protein 1(SYCE1)and stromal antigen 3(STAG3)in azoospermic men.In conclusion,FertilityOnline is not only an integrated resource for spermatogenic genes but also a useful tool facilitating the exploration of the genetic basis of male infertility.

Background/Aims: Colorectal cancer (CRC) patients often exhibit peritoneal metastasis, which negatively impacts their prognosis. CD31 and D2-40 have recently been suggested to be predictors of breast cancer prognosis, but their role in colorectal peritoneal metastasis (CRPM) remains unknown. Methods: The expression profiles of CD31 and D2-40 were analyzed in CRC patients with or without CRPM and in CRC cell lines with increasing metastatic potential. Overexpression and short hairpin RNA knockdown assays were performed in CRC cells, and the effects of these alterations on epithelial-mesenchymal transition (EMT) in vitro, growth of xenograft tumors in vivo, and peritoneal metastasis potential in a mouse model of CRPM were examined. Results: The expressions of CD31 and D2-40 were upregulated in CRC tumor tissues and was elevated further in tumor tissues from patients with CRPM. CD31 and D2-40 expression levels exhibited increasing trends parallel to the EMT potential of CRC cells. CD31 and D2-40 are essential for CRC cell EMT in vitro as well as for xenograft tumor growth and peritoneal metastasis in vivo. Conclusions CD31 and D2-40 contribute to CRPM by promoting EMT and may serve as prognostic markers and therapeutic targets for CRC, particularly in patients with peritoneal metastasis.
