Objective To investigate the predictive value of the expression levels of YY1 transcription fac-tor(YY1)and microRNA(miR)-181a-5p in peripheral blood mononuclear cell for adverse pregnancy out-comes in gestational diabetes mellitus(GDM).Methods A total of 200 patients with GDM were enrolled as the GDM group.100 healthy pregnant women who underwent prenatal examinations during the same period were selected as the control group.The expressions levels of YY1 and miR-181a-5p in peripheral blood mono-nuclear cell were detected by fluorescent quantitative PCR.Receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of YY1 and miR-181a-5p for adverse pregnancy outcomes in GDM pa-tients.Results Compared with the control group,the expression levels of YY1 and miR-181a-5p in peripheral blood mononuclear cell of GDM group were obviously decreased(P＜0.05),and the incidence rates of post-partum hemorrhage,macrosomia and neonatal hypoglycemia in GDM group were obviously higher(P＜0.05).Multivariate Logistic regression analysis showed that age and poor blood glucose control were inde-pendent risk factors for adverse pregnancy outcomes in GDM patients(P＜0.05),and the expression levels of peripheral blood mononuclear cell YY1 and miR-181a-5p were independent protective factors for adverse preg-nancy outcomes in GDM patients(P＜0.05).ROC curve results showed that the area under the curve(AUC)of the expression levels of YY1 and miR-181a-5p in peripheral blood alone and in combination in predicting ad-verse pregnancy outcomes in GDM patients was 0.717,0.751 and 0.832,respectively,and the AUC of their combination was obviously higher than that of the two alone(P＜0.05).Conclusion The decreased expres-sion levels of YY1 and miR-181a-5p in peripheral blood mononuclear cell of GDM patients could increase the risk of adverse pregnancy outcomes,YY1 and miR-181a-5p are closely related to adverse pregnancy outcomes in GDM patients,and both could be used as predictors of adverse pregnancy outcomes in GDM patients.

Objective:To determine the total and age-specific cut-off values of total prostate specific antigen (tPSA) and the ratio of free PSA divided total PSA (fPSA/tPSA) for screening prostate cancer in China.Methods:Based on the Chinese Colorectal, Breast, Lung, Liver, and Stomach cancer Screening Trial (C-BLAST) and the Tianjin Common Cancer Case Cohort (TJ4C), males who were not diagnosed with any cancers at baseline since 2017 and received both tPSA and fPSA testes were selected. Based on Cox regression, the overall and age-specific (＜60, 60-＜70, and ≥70 years) accuracy and optimal cut-off values of tPSA and fPSA/tPSA ratio for screening prostate cancer were evaluated with time-dependent receiver operating characteristic curve (tdROC) and area under curve (AUC). Bootstrap resampling was used to internally validate the stability of the optimal cut-off value, and the PLCO study was used to externally validate the accuracy under different cut-off values.Results:A total of 5 180 participants were included in the study, and after a median follow-up of 1.48 years, a total of 332 prostate cancer patients were included. In the total population, the tdAUC of tPSA and fPSA/tPSA screening for prostate cancer were 0.852 and 0.748, respectively, with the optimal cut-off values of 5.08 ng/ml and 0.173, respectively. After age stratification, the age specific cut-off values of tPSA in the <60, 60-<70, and ≥70 age groups were 3.13, 4.82, and 11.54 ng/ml, respectively, while the age-specific cut-off values of fPSA/tPSA were 0.153, 0.135, and 0.130, respectively. Under the age-specific cut-off values, the sensitivities of tPSA screening for prostate cancer in males <60, 60-70, and ≥70 years old were 92.3%, 82.0%, and 77.6%, respectively, while the specificities were 84.7%, 81.3%, and 75.4%, respectively. The age-specific sensitivities of fPSA/tPSA for screening prostate cancer were 74.4%, 53.3%, and 55.9%, respectively, while the specificities were 83.8%, 83.7%, and 83.7%, respectively. Both bootstrap's internal validation and PLCO external validation provided similar results. The combination of tPSA and fPSA/tPSA could further improve the accuracy of screening.Conclusion:To improve the screening effects, it is recommended that age-specific cut-off values of tPSA and fPSA/tPSA should be used to screen for prostate cancer in the general risk population.

Objective To develop multimodal joint cognitive representations for the research of visual cognitive activities of the brain,enhance the classification performance of visual information cognitive representations,predict brain electro-encephalogram(EEG)responses from visual image features,and decode visual images from EEG signals.Methods A architecture combining a multimodal variational autoencoder network with the Mixture of Product Experts(MoPoE)approach and with a style generation adversarial network based on adaptive discriminator augmentation(Style-GAN2-ADA)was used for facilitating the learning of cognitive representations and the encoding and decoding of EEG signals.This framework not only catered to classification tasks but also enabled cross-modal generation of images and EEG data.Results The present study integrated features from different modalities,enhancing the classification accuracy of cognitive representations of visual information.By aligning the feature spaces of diverse modalities into a cohesive latent space,cross-modal generation tasks were made possible.The cross-modal generation results of EEG and images,derived from this unified latent space,outperformed the one-way mapping methods that involved transition from one modality to another employed in previous research.Conclusion This study effectively integrates and aligns information from various modalities,enabling the classification performance of joint cognitive representations beyond any single modality.Moreover,the study demonstrates superior outcomes in cross-modal generation tasks compared to modality-specific unidirectional mappings,which is expected to offer a new line of thought for the effective unified encoding and decoding modeling of visual cognitive information in the brain.

Objective To investigate the imaging findings,clinical diagnosis and treatment outcomes of ovarian epithelial tumors during pregnancy.Methods Nineteen patients confirmed pathologically to be ovarian epithelial tumors during pregnancy were retro-spectively reviewed.All patients'clinical and imaging datas were analyzed in order to provide a basis for accurate diagnosis and treat-ment.Results There were 19 patients with 22 tumors,among of which 11 were benign tumors,3 borderline tumors and 5 malignant tumors.All tumors were composed of cystic or cystic-solid components,mainly polycystic.Mural nodules could be seen in 3 cases of borderline or malignant tumors.Obvious enhancement of solid components,septas and mural nodules could be seen on contrast-enhanced scans.Other imaging findings included pelvic effusion 2 cases,the adjacent tissues or organs displacement due to mass effect.Definite invasion of adjacent structures and distant metastases was not found.Conclusion There is no significant difference in the age,loca-tion,size and number of cysts between ovarian epithelial tumors during pregnancy and non-pregnancy,but the incidence of complica-tions increases due to physiological changes related to pregnancy.Early diagnosis and timely treatment are of great value.

Objective:To understand the current status of human resources in Operating Room nursing in China, so as to provide reference for nursing management, human resource allocation, nursing education and training in Operating Rooms.Methods:Using the stratified sampling method, a self-made Operating Room nursing human resource survey questionnaire of Chinese Nursing Society was used as a research tool in July 2021 to investigate the general situation, surgical workload, human resource allocation, Operating Room management, Operating Room information construction, nursing education and training of 2 201 hospitals in 31 provinces, autonomous regions and municipalities of China.Results:Among the 2 201 hospitals, there were 1 021 tertiary hospitals (46.39%), 1 177 secondary hospitals (50.75%), and 63 primary and below hospitals (2.86%). There were 2 056 hospitals with less than 30 Operating Rooms, accounting for 93.41%. There were 1 991 hospitals with an annual number of surgical cases less than 20 000, accounting for 90.46%, the educational background of Operating Room nurses was mainly undergraduate (66.93%, 43 359/64 780), with a total of 67.99% (44 045/64 780) having a bachelor's degree or above. Nurses were the main professional titles (42.66%, 27 632/64 780). Number of Operating Rooms: the number of Operating Room nurses (median) was 1: 2.43 and 78.96% (1 738/2 201) of hospital operating theatres were managed by Nursing Departments or hospitals. A total of 1 479 hospitals (67.20%) established anesthesia recovery rooms in their Operating Rooms, which was higher than 59.34% (1 210 hospitals) surveyed in 2016, and the difference was statistically significant (χ 2=226.701, P<0.01). 74.69% (1 644/2 201) and 87.87% (1 934/2 201) of hospitals carried out post management and capacity classification management in Operating Rooms, respectively. Day surgery and robotic surgery were performed in 47.80% (1 052/201) and 7.68% (169/2 201) hospitals, respectively. 36.98% (814/2 201) of the hospitals passed the information evaluation system certification and 64.61% (1 422/2 201) of the hospitals used the Operating Room information management system. In the Operating Room information system of the hospital, 2.54% (56/2 201) had intelligent functions. And 77.24% (1 700/2 201) of hospitals participated in the qualification training of Operating Room specialist nurses. Conclusions:By July 2021, the number of Operating Rooms in most hospitals in China is less than 30, and the annual number of operating cases is less than 20 000. The educational background and professional title of Operating Room nurses are mainly undergraduate and nurse. More than 60% of hospitals have set up anesthesia recovery rooms and have information management systems for Operating Rooms. At the same time, Operating Rooms in Chinese hospitals have widely implemented diversified nursing management models such as post management and ability grading management.

Objective:To explore the relationship between insomnia and osteoporosis.Methods:Mendelian randomization (MR) analysis were used in this study. The single nucleotide polymorphisms (SNPs) related to insomnia from genome-wide association analysis research data were selected as the instrumental variables by using inverse variance weighted (IVW), MR-Egger regression, weighted median method, maximum likelihood, penalized weighted median estimator, and Mendelian randomization robust adjusted profile score (MR-RAPS) to determine the causal relationship between insomnia and osteoporosis. Odds ratio ( OR) and 95% confidence interval ( CI) values were used to evaluate the association between insomnia and osteoporosis. Cochran′s Q-test was used to detect heterogeneity of SNPs, MR-Egger regression was used to test for level pleiotropy, and the leave-one-out method was used to test sensitivity, MR pleiotropy residual sum and outlier (MR-PRESSO) method and radial MR were used to detect erroneous outliers. Results:The screening criteria were set based on the three major assumptions of MR; finally, 31 SNPs were included in the MR analysis. The results of MR causal effect analysis using the IVW method showed that insomnia increased the risk of osteoporosis by about 0.7% ( OR=1.007, 95% CI 1.001-1.014, P=0.044); heterogeneity testing showed heterogeneity between SNPs ( Q=57.91, P<0.001); and the MR- Egger intercept test did not indicate horizontal pleiotropy in this study (intercept value=3.807×10 -5, P=0.888). Leave-one-out method showed that no single SNP had a significant impact on the overall results. No abnormal SNP was detected according to the MR-PRESSO results ( P=0.059), and radial MR did not detect any outliers. Conclusion:Mendelian randomization analysis showed that insomnia can increase the risk of osteoporosis.

Objective:To evaluate the preliminary effectiveness and safety of surgical peripheral iridectomy (SPI) combined with goniosynechilysis (GSL) and goniotomy (GT) in the treatment of advanced primary angle-closure glaucoma (PACG).Methods:A multicenter observational case series study was performed.Thirty-five eyes of 27 patients with advanced PACG, who underwent SPI+ GSL+ GT with a follow-up of at least 6 months, were included from August 2021 to January 2022 at Zhongshan Ophthalmic Center, Handan City Eye Hospital, Shijiazhuang People's Hospital, West China Hospital of Sichuan University, and the Third Affiliated Hospital of Chongqing Medical University.The mean follow-up time was 9(7, 10) months.Pre- and post-operative best corrected visual acuity (BCVA) and intraocular pressure (IOP) were measured with an ETDRS chart and a Goldmann applanation tonometer, respectively.The number of anti-glaucoma medications applied before and after surgery was recorded, and the complications after surgery were analyzed.Success rate of surgery was calculated.Complete surgical success was defined as an IOP of 5-18 mmHg (1 mmHg=0.133 kPa) and 20% reduction from baseline without anti-glaucoma medication or reoperation.Qualified success was defined as achieving criterion of complete success under anti-glaucoma medications.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Zhongshan Ophthalmic Center, Sun Yat-sen University (No.2021KYPJ177). Written informed consent was obtained from each subject.Results:The mean preoperative IOP was (30.83±8.87)mmHg, which was significantly decreased to (15.69±3.70)mmHg at 6 months after the surgery ( t=8.588, P<0.001), with a 44.00% (34.78%, 60.00%) decline of 13.00(8.00, 21.00)mmHg.The median number of anti-glaucoma medications was significantly reduced from 2(0, 3) preoperatively to 0 (0, 1) postoperatively ( Z=-3.659, P<0.001). The mean preoperative and postoperative 6-month BCVA were 0.80(0.63, 1.00) and 0.80(0.60, 1.00), respectively, showing no significant difference ( Z=-0.283, P=0.777). Complete surgical success rate was 62.86%(22/35), and the qualified success rate was 91.43%(32/35). Surgical complications mainly included hyphema (6/35), IOP spike (3/35), and shallow anterior chamber (4/35). There was no vision-threatening complication. Conclusions:SPI+ GSL+ GT is preliminarily effective and safe in the treatment of advanced PACG, which provides a new option for PACG.

Objective    To compare and investigate the efficacy and differences of modified B-T shunt, central shunt and right ventricle-pulmonary artery (RV-PA) connection in the treatment of pulmonary atresia with ventricular septal defect (PA/VSD). Methods    A total of 124 children with PA/VSD underwent initial palliative repair in Shanghai Children's Medical Center from September 2014 to August 2019, including 63 males and 61 females, aged 7 days to 15 years. They were divided into in a modified B-T shunt group (55 patients), a central shunt group (22 patients) and a RV-PA connection group (47 patients). The clinical data of these children were retrospectively analyzed. Results    There were 9 early deaths after palliation, with an early mortality rate of 7.3%. The mean follow-up time was 26.5±20.3 months, with 5 patients lost to follow-up, 5 deaths during the follow-up period, and 105 survivors. The 1-year and 5-year survival rates were both 89.7%. The monthly increased Nakata index was 5.2 (–0.2, 12.3) mm2/m2, 9.2 (0.1, 23.6) mm2/m2, 6.3 (1.8, 23.3) mm2/m2 in the modified B-T shunt group, the central shunt group, and the RV-PA connection group, respectively, with no statistical difference among the three groups. The 1-year survival rate was 85.3%, 78.4%, 95.2%, and the 5-year (4-year in the central shunt group) survival rate was 85.3%, 58.8%, 95.2% in the three groups, respectively, with a statistical difference among them (P<0.05). The complete repair rate was 36.5%, 19.0% and 67.4% in the three groups, respectively, with a statistical difference among the three groups (P<0.001). Conclusion    All these three palliative surgical approaches can effectively promote pulmonary vascular development. But compared with systemic-pulmonary shunt, RV-PA connection has a lower perioperative mortality rate and can achieve a higher complete repair rate at a later stage, which is beneficial for long-term prognosis.

OBJECTIVE: To analyze the flow immunophenotype and clinical characteristics of leukemia patients with positive SET-CAN fusion gene. METHODS: A total of 7 newly diagnosed acute leukemia patients with SET-CAN fusion gene admitted to Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology from February 2016 to February 2020 were collected. Multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the expression of SET-CAN fusion gene. The immunophenotype was detected by four-color flow cytometry. The case information of 17 literatures published at home and abroad was extracted for statistical analysis. RESULTS: Among the 7 patients, 2 cases were diagnosed as mixed phenotype acute leukemia (MPAL), 2 cases as acute myeloid leukemia (AML), and 3 cases as T-acute lymphoblastic leukemia (ALL)/lymphoblastic lymphoma (LBL). Leukemia cells in bone marrow specimens of all cases expressed or partially expressed CD34, CD33 and CD7. CD5 and cytoplasmic CD3 were expressed in 5 patients except 2 patients diagnosed with AML. Bone marrow and lymph node specimens were both detected in 2 patients, and the immunophenotypes of the two specimens were not completely consistent, with differences in lineage or maturity related markers. Two patients with MPAL showed differentiated response to treatment. One AML patient gave up treatment, and another AML patient with FLT3-ITD gene mutation had a poor prognosis. All three T-ALL/LBL patients maintained a long duration of remission after induced remission, and one case underwent allogeneic hematopoietic stem cell transplantation. CONCLUSIONS There are common characteristics of immunophenotype in patients with positive SET-CAN fusion gene. Differential expression of immunophenotype in samples from different parts is observed in some cases. The prognosis of these diseases varies.
