Abstract
Objective: To study the clinical characteristics of cornual pregnancy and compare the effects of various surgical methods on the outcomes. Methods: This was a single-center retrospective study. The clinical records of patients with cornual pregnancy who underwent surgery in Peking Union Medical College Hospital from June 2012 to December 2020 were collected. Surgical interventions included curettage (guided by ultrasound or monitored by laparoscope), and cornuostomy/cornectomy (the surgical approach by laparoscopy or laparotomy). The baseline data, perioperative treatment and whether persistent ectopic pregnancy (PEP) occurred after surgery were collected and analyzed statistically. Results: A total of 109 patients with cornual pregnancy diagnosed by surgical treatment were included in this study, whose average age was (32.9±4.8) years. Among them, the incidence of postoperative PEP was 16.5% (18/109). The risk of PEP in multipara was significantly higher than that in nulliparous women (OR=7.639, 95%CI: 2.063-28.279, P=0.001). The risk of PEP in patients with the maximum diameter of lesion<1.5 cm was significantly higher than that in patients with the maximum diameter of lesion≥1.5 cm (OR=8.600, 95%CI: 2.271-32.571, P=0.002). Among all surgical approaches for cornual pregnancy, the proportion of PEP in curettage under ultrasound monitoring was the highest (56.0%, 14/25), which was higher than that in curettage under laparoscope monitoring (1/10; χ2=6.172,P=0.013); the proportion of PEP in curettage group (42.9%, 15/35) was higher than that in cornuostomy/cornectomy group (4.1%, 3/74; χ2=25.950,P<0.01). Neither salpingectomy in the operation nor the routine use of methotrexate (MTX) in perioperative period could significantly reduce the incidence of PEP (all P>0.05). Conclusions: Among the patients with cornual pregnancy, multipara, the maximum diameter of lesion<1.5 cm and ultrasound-guided curettage are the risk factors of PEP after operation. Cornuostomy or cornectomy is recommended for patients with cornual pregnancy. If the patients would perform the curettage operation, laparoscopic monitoring is recommended. For patients with possible satisfactory operation outcome, it is not recommended to use MTX as a routine preventing measure.

Abstract
Objectives: To investigate the prevalence and associated risk factors of tinnitus in Sichuan and Chongqing. Methods: We designed a tinnitus epidemiological questionnaire. The multi-stage stratified cluster random sampling methods was applied to obtain study subjects in six areas (Nanchong, Jiangjin, Fengdu, Yunyang, Suining and Ya'an), which were selected for epidemiological investigation. Home visit completion of epidemiological questionnaires was conducted. The trained investigators guided the respondents to fill in the tinnitus epidemiological questionnaires, and the epidemiological status of six areas on prevalence and risk factor was investigated. SPSS 22.0 software was used for statistical analysis. Results: Sampling population were 10 289, in which 9 273 were valid questionnaires. There were 4 281 males and 4 992 females, with an average age of 47.3 years, among which 34.83% (3 230/9 273) had tinnitus. 3.99% (370/9 273) were diagnosed with bothersome tinnitus. In a multivariable logistic regression mod, the following factors were associated with onsetting of tinnitus: sleep disorder [Odds Ratio(OR)=3.74] and noise exposure(OR=1.99). The risk of disease was lowest in the age of 30-40 years old, while the risk of disease was higher for people under 30 and over 40. In another multivariable logistic regression mode, the following factors were associated with having bothersome tinnitus: older people were more likely to suffer from tinnitus, sleep disorders (OR=4.68) and noise exposure (OR=1.56). Conclusions: The prevalence of tinnitus in Sichuan and Chongqing is about 34.83%, but most of the tinnitus is short-lived and has low loudness, which will not affect the patients. Only a small number of patients with tinnitus (3.99%) persist and affect their health and need treatment. The occurrence and exacerbation of tinnitus may be related to sleep, age, and noise exposure.

Abstract
PURPOSE Glioblastoma multiforme (GBM) is one of the most common malignant brain tumors in adults and has high mortality and relapse rates. Over the past few years, great advances have been made in the diagnosis and treatment of GBM, but unfortunately, the five-year overall survival rate of GBM patients is approximately 5.1%. Inhibitor of nuclear factor kappa-B kinase subunit epsilon (IKBKE) is a major oncogenic protein in tumors and can promote evil development of GBM. Snail1, a key inducer of the epithelial-mesenchymal transition (EMT) transcription factor, is subjected to ubiquitination and degradation, but the mechanism by which Snail1 is stabilized in tumors remains unclear. Our study aimed to investigate the mechanism of IKBKE regulating Snail1 in GBM. METHODS First, we analyzed the correlation between the expression of IKBKE and the tumor grade and prognosis through public databases and laboratory specimen libraries. Second, immunohistochemistry (IHC) and western blot were used to detect the correlation between IKBKE and Snail expression in glioma samples and cell lines. Western blot and immunofluorescence (IF) experiments were used to detect the quality and distribution of IKBKE and Snail1 proteins. Third, In situ animal model of intracranial glioma to detect the regulatory effect of IKBKE on intracranial tumors. RESULTS In this study, Our study reveals a new connection between IKBKE and Snail1, where IKBKE can directly bind to Snail1, translocate Snail1 into the nucleus from the cytoplasm. Downregulation of IKBKE results in Snail1 destabilization and impairs the tumor cell migration and invasion capabilities. CONCLUSION Our studies suggest that the IKBKE-Snail1 axis may serve as a potential therapeutic target for GBM treatment.

Abstract
Objective: To compare the value of 25-hydroxyvitamin D3 (25-(OH)D3) with other clinical parameters in the prediction and diagnosis of eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP). Methods: Eligible chronic rhinosinusitis with nasal polyps (CRSwNP) patients and healthy subjects in the Affiliated Hospital of Guizhou Medical University from January to April of 2021 were included for this study. The age, gender, past history and other basic characteristics of all subjects were recorded. The CRSwNP patients were classified into ECRSwNP and non-eosinophilic chronic rhinosinusitis with nasal polyps (nECRSwNP) endotypes by the percentage of tissue eosinophils. Serum 25-(OH)D3 levels measurements were performed in all subjects. Paranasal sinus CT scans, blood eosinophil counts, and determination of total immunoglobulin E (total IgE), Th1/Th2 plasma cytokines and nasal nitric oxide (nNO) levels were performed before surgery. Logistic regression analysis was used to evaluate the related factors of ECRSwNP. Receiver operating characteristic (ROC) curves was used to evaluate the predictive potential of the clinical parameters. Results: One hundred and twenty-seven CRSwNP patients and 40 healthy subjects were recruited, including 74 males and 93 females of the patients, with the age of (38.73±13.05) years. In patients with ECRSwNP, serum 25-(OH)D3 levels were significantly lower than those in nECRSwNP patients ((26.14±4.58) ng/ml vs (35.71±7.86) ng/ml, t=-8.564, P<0.01). The prevalence of asthma, prevalence of allergic rhinitis, peripheral blood eosinophil counts, total IgE levels, nNO levels and CT scores ratio for ethmoid sinus and maxillary sinus (E/M ratio) of ECRSwNP patients were significantly higher than those in nECRSwNP patients (all P<0.05). However, there was no significant difference in Th1/Th2 cytokines levels between the histological types of CRSwNP (all P>0.05). Among the predictive indicators, 25-(OH)D3 had the highest predictive value, with ROC area under curve (AUC) value of 0.882. The best cut-off point of 28.5 ng/ml for 25-(OH)D3 demonstrated a sensitivity of 0.871 and a specificity of 0.762 for ECRSwNP. Conclusion: Measurement of serum 25-(OH)D3 level may be used as an effective method to distinguish between ECRSwNP and nECRSwNP.

Abstract
OBJECTIVE To estimate the incidence of urinary incontinence (UI), including its subtypes stress UI (SUI), urgency UI (UUI) and mixed UI (MUI), and to examine risk factors for de novo SUI and UUI in Chinese women. DESIGN Nationwide longitudinal study. SETTING Six geographic regions of China. PARTICIPANTS Women aged ≥20 years old were included using a multistage, stratified, cluster sampling method. METHODS This study was conducted between May 2014 and March 2016, with follow up in 2018. Data on demographics, medical history, lifestyle and physiological and anthropometric information were collected. MAIN OUTCOME MEASUREMENTS Incidence, rate ratio (RR). RESULTS Analyses included 24 985 women (mean age 41.9 years).The follow-up response rate was 55.5%, median follow-up time was 3.7 years. The standardised incidences of UI, SUI, UUI and MUI were 21.2, 13.1, 3.0 and 5.1 per 1000 person-years, respectively. Risk factors for de novo SUI included delivery pattern (vaginal spontaneous delivery RR 2.12, 95% CI 1.62-2.78 and instrumental delivery RR 3.30, 95% CI 1.99-5.45), high body mass index (BMI) (overweight RR 1.52, 95% CI 1.33-1.74 and obesity RR 1.67, 95% CI 1.32-2.11), cigarette smoking (RR 1.54, 95% CI 1.12-2.12), chronic cough (RR 1.44, 95% CI 1.17-1.76), diabetes (RR 1.33, 95% CI 1.10-1.60) and older age (50-59 years RR 1.49, 95% CI 1.16-1.90 and 60-69 years RR 1.61, 95% CI 1.22-2.13).The risk factors significantly associated with de novo UUI were age (RR increased from 1.21, 95% CI 0.74-1.99, at 30-39 years to 6.3, 95% CI 3.85-10.30, at >70 years) and diabetes (RR 1.48, 95% CI 1.05-2.09). CONCLUSIONS The incidence of female UI is 21.2 per 1000 person-years in China. Delivery (vaginal spontaneous delivery, instrumental delivery), high BMI, cigarette smoking, chronic cough, diabetes and older age were risk factors. TWEETABLE ABSTRACT The incidence of female urinary incontinence was 21.2 per 1000 person-years in China. Delivery, BMI, diabetes and old age are risk factors.

Abstract
BACKGROUND Continuous spike and wave of sleep with encephalopathy (CSWS) is a rare and severe developmental electroclinical epileptic encephalopathy characterized by seizures, abundant sleep activated interictal epileptiform discharges, and cognitive regression or deceleration of expected cognitive growth. The cause of the cognitive symptoms is unknown, and efforts to link epileptiform activity to cognitive function have been unrevealing. Converging lines of evidence implicate thalamocortical circuits in these disorders. Sleep spindles are generated and propagated by the same thalamocortical circuits that can generate spikes and, in healthy sleep, support memory consolidation. As such, sleep spindle deficits may provide a physiologically relevant mechanistic biomarker for cognitive dysfunction in epileptic encephalopathies. CASE PRESENTATION We describe the longitudinal course of a child with CSWS with initial cognitive regression followed by dramatic cognitive improvement after treatment. Using validated automated detection algorithms, we analyzed electroencephalograms for epileptiform discharges and sleep spindles alongside contemporaneous neuropsychological evaluations over the course of the patient's disease. We found that sleep spindles increased dramatically with high-dose diazepam treatment, corresponding with marked improvements in cognitive performance. We also found that the sleep spindle rate was anticorrelated to spike rate, consistent with a competitively shared underlying thalamocortical circuitry. CONCLUSIONS Epileptic encephalopathies are challenging electroclinical syndromes characterized by combined seizures and a deceleration or regression in cognitive skills over childhood. This report identifies thalamocortical circuit dysfunction in a case of epileptic encephalopathy and motivates future investigations of sleep spindles as a biomarker of cognitive function and a potential therapeutic target in this challenging disease.

Abstract
Abstract
BACKGROUND
The diagnosis of brain metastasis involves high morbidity and mortality and remains an unmet clinical need in spite of being the most common tumor in the brain. Exclusion of these cancer patients from clinical trials is a major cause of their limited therapeutic options.
MATERIAL AND METHODS
We report a novel drug-screening platform (METPlatform) based on organotypic cultures which allows identifying effective anti-metastasis agents in the presence of the organ microenvironment. We have applied this approach to clinically relevant stages of brain metastasis using both experimental models and human tumor tissue (by performing patient-derived organotypic cultures - PDOCs -). We have also used METPlatform to perform unbiased proteomics of brain metastases in situ to identify potential novel mediators of this disease and explore resistance mechanisms to targeted therapy. Finally, we have exploited METPlatform as “avatars” to predict response to therapy in patients with primary brain tumors.
RESULTS
We identified heat shock protein 90 (HSP90) as a promising therapeutic target for brain metastasis. DEBIO-0932, a blood-brain barrier permeable HSP90 inhibitor, shows high potency against mouse and human brain metastases from different primary origin and oncogenomic profile at clinically relevant stages of the disease, including a novel model of local relapse after neurosurgery. Furthermore, in situ proteomic analysis of brain metastases treated with the chaperone inhibitor revealed non-canonical clients of HSP90 as potential novel mediators of brain metastasis and actionable mechanisms of resistance driven by autophagy. Combined therapy using HSP90 and autophagy inhibitors showed synergistic effects compared to sublethal concentrations of each monotherapy, demonstrating the potential of METPlatform to design and test rationale combination therapies to target metastasis more effectively. Finally, we show that brain tumor PDOCs predict the response of the corresponding patient to standard of care, thus proving the potential of METPlatform for improving personalized care in cancer.
CONCLUSION
Our work validates METPlatform as a potent resource for metastasis research integrating drug-screening and unbiased omic approaches that is fully compatible with human samples and questions the rationale of excluding patients with brain metastasis from clinical trials. We envision that METPlatform will be established as a clinically relevant strategy to personalize the management of metastatic disease in the brain and elsewhere.

Abstract
1. A better understanding of intestinal development is essential for the intestinal health of poultry. Intestinal villification starts on embryo day E15 and is generally completed before hatching (E21). The development of lymphoid organs in the intestine starts during embryogenesis. However, transcriptional information on the processing of intestinal morphogenesis and immune development during chick embryogenesis is limited.2. In this work, RNA-sequencing was performed using 12 biological replicates to investigate Hy-Line brown chick embryonic small intestinal transcription at E15 and E21. Differentially expressed genes (DEGs) between E15 and E21 were identified. GO and KEGG enrichment analyses, based on the DEGs, were performed to identify key GO terms in the biological process category and key KEGG pathways. PPI networks were constructed based on the DEGs in the key pathways to screen hub genes. The embryonic small intestinal morphology and IgA distribution were observed by histological processing. The serum levels of IgA and lysozyme were measured by ELISA.3. A total of 76.38 Gb of high-quality RNA-sequencing data were generated and uploaded. A total of 2,676 DEGs, between E15 and E21, were identified. Structural development and villification of the small intestine at E15 tended to proceed via the expression of nervous system development-related genes. A combination of the histological and serological results with the transcriptome data indicated that the identified genes and pathways may be strong candidates for intestinal morphogenesis-regulation.4. The small intestine appears to have developed a relatively complete morphology and transport, metabolism, digestion and immunity functions by E21. This work provided a transcriptome profile of the chick embryonic small intestine and provided insights into the intestinal development and health of poultry.

Abstract
Abstract
Study question
Does repeated cryopreservation process effect embryo implantation potential and neonatal outcomes of human embryos?
Summary answer
Repeated cryopreservation impaired embryo implantation potential, resulting in a lower live birth rate and higher miscarriage rate, despite a comparable neonatal complication rate.
What is known already
With significant advances in the field of ART, the number of available embryos for transfer per cycle has also increased, resulting in a slew of surplus embryo cryopreservation. However, limited researches have focused on the embryonic development potential, clinical outcomes, pregnancy complications as well as the neonatal complications of embryos experiencing repeated cryopreservation.
Study design, size, duration
This was a retrospective, single-center cohort study. All ART cycles from January 2014 to December 2018. Age, body mass index, and number of oocytes retrieved were preferentially matched within a required range, with a total of 709 couples included in the study.
Participants/materials, setting, methods
The study was conducted in the Reproductive Medicine Centre affiliated to a university. Preferentially matched participants were divided into three groups according to the times of embryo cryopreservation: the fresh group (n = 249), the cryopreservation group (n = 244) and the re-cryopreservation group (n = 216). Embryo implantation rate, live birth rate, miscarriage rate, and neonatal complication rate were compared among these three groups.
Main results and the role of chance
The embryo implantation rate, clinical pregnancy rate and live birth rate in the re-cryopreservation group were significantly lower, and there was also a slight increase in the miscarriage rate. Logistic regression analysis indicated that embryos with repeated cryopreservation and lower TE scores were at higher risk of embryo implantation failure in single embryo transfer cycles (OR = 1.79 and 1.56 respectively). No significant differences were observed in gender, gestational age, birthweight, neonatal abnormality, and neonatal complications among the groups.
Limitations, reasons for caution
This was a retrospective cohort study conducted in single center. A multi-center prospective study with a larger sample size in well-matched participants is needed to reinforce our findings.
Wider implications of the findings: Our findings demonstrated the adverse effect of repeated cryopreservation on embryo implantation potential. To avoid embryo waste, or in some special circumstances such as re-biopsy in PGT cycles, an additional cryopreservation on embryos was considered to be available to achieve clinical pregnancy and live birth.

Abstract
Objective: To investigate the long-term mesh-related complications and treatment outcome of total pelvic reconstruction surgery with tension-free transvaginal mesh (PROSIMATM pelvic floor repair system). Methods: From July 2010 to June 2012, 48 patients with severe pelvic organ prolapse(POP)who underwent PROSIMATM were enrolled and treated in Peking Union Medical College Hospital. 29 patients (60.4%) were followed up periodically for at least 3 years to observe the occurrence of long-term mesh-related complications, and the clinical characteristics, classification of complications and treatment outcome of these cases were summarized. Results: The 29 cases with an average age of (65.1±5.2) years were followed up for an average of (71.6±21.2) months. The last follow-up was 36-105 months after treatment. The long-term success rate of the treatment was 79.3% (n=23). There were 18 cases of mesh exposure (18/48, 37.5%), of which 10 cases (55.6%) were new and persistent. 4 cases (4/18) had symptoms; the rest were found by pelvic examination. Ten patients (10/18) were positive for vaginal swab culture. As for treatment outcome, one case suffered from mesh erosion into the bladder. 4 patients (6.9%) complained of postoperative pain. Twenty-nine patients were divided into the exposure group (n=18) and the non-exposure group (n=11) according to mesh exposure occurrence. There was a significant difference in the proportion of positive swab culture results between the two groups (P=0.019), but no significant difference in the incidence of postoperative pain (P=0.566). Conclusion: The incidence of long-term mesh exposure in PROSIMATM is not low, and most of patients with which had no symptoms.

Abstract
Cytoskeletal protein β-actin is abundant both in the cytoplasm and the nucleus, its mRNA is commonly utilized an internal control for gene expression analysis. Recent reports demostrated that hypoxia influences the levels of β-actin in a variety of cells. The mechanism underlying this change are not yet elucidated. In this work, we show that the changes in the levels of hypoxia-induced Nuclear respiratory factor-1 (NRF-1) lead to the change in expression of β-actin. We compared the protein levels of NRF-1 and β-actin in gastric cancer and adjacent tissues and found their significantly upregulation in cancer (33% patitents). When gastric cancer cells and normal gastric cells were treated with 1% O2 for 48 h, the trends in expression levels of NRF-1 and β-actin were similar. When NRF-1 expression was modified by its overexpressing or silencing, the levels of β-actin changed accordingly. In β-actin gene (ACTB), three binding sites for NRF-1 were found. These sites are conserved in human, mouse and rat genomes. In ChIP experiments, we showed that NRF-1 directly binds to human ACTB and mouse Actb coding regions. Its seems that the transcription of β-actin encoding gene is NRF-1 dependent.

Abstract
The Coatomer protein complex subunit beta 2 (COPB2) is involved in the formation of the COPI coatomer protein complex and is responsible for the transport of vesicles between the Golgi apparatus and the endoplasmic reticulum. It plays an important role in maintaining the integrity of these cellular organelles, as well as in maintaining cell homeostasis. More importantly, COPB2 plays key roles in embryonic development and tumor progression. COPB2 is regarded as a vital oncogene in several cancer types and has been implicated in tumor cell proliferation, survival, invasion, and metastasis. Here, we summarize the current knowledge on the roles of COPB2 in cancer development and progression in the context of the hallmarks of cancer.

Abstract
Objective: To investigate the impact of perioperative anesthesia management with enhanced recovery after surgery (ERAS) strategy on postoperative recovery in patients undergoing laparoscopic surgery for gynecologic malignancy. Methods: Ninety patients undergoing laparoscopic surgery for gynecologic malignancies from April 2018 to April 2019,aged 18-65 years,with American Society of Anesthesiologists (ASA) physical status Ⅰ or Ⅱ, were recruited and randomly divided into two groups (n=45) using a random number table:ERAS group (group E) and control group (group C). Patients in group E received general anesthesia combined with transverses abdominis plane block and a series of interventions to optimize anesthetic and perioperative management, while patients in group C were treated with routine anesthesia management. Quality of Recovery-40 questionnaire (QoR-40) was administered to assess the early postoperative quality of recovery on 1 day before surgery, and at 24 and 48h after surgery. C-reactive protein (CRP) before and after the operation were evaluated. The incidence of nausea, vomiting and shivering, the time of first exhaust, ambulation, resumption of normal diet, postoperative hospital stay and complications were recorded. Results: The scores of QoR-40 [M(Q1, Q3)] in Group E were 175(171, 179) and 185(183, 189) at 24 h and 48 h after operation, which were higher than those in group C [162(160, 167) and 180(179, 183)] (both P<0.01). The levels of CRP in both group E and group C increased at 24 h and 72 h after operation. Moreover, the extent of increasing level of CRP in group C was much higher than that in group E [(39.8±18.0) mg/L vs (13.4±6.3) mg/L, (16.6±8.6) mg/L vs (6.7±2.5) mg/L] at 24 h and 48 h after operation (both P<0.01). Compared with group C, the numerical rating scale (NRS) for nausea decreased significantly in group E [0(0, 2) vs 3 (0, 5), P<0.01]. Meanwhile, the incidence of vomiting and shivering in group E was lower than that in group C [8.9% (4/45) vs 26.7% (12/45); 11.1% (5/45) vs 31.1% (14/45); both P<0.05]. The time of first exhaust, ambulation and resumption of normal diet in group E was (14±6) h, 6(6, 13) h and 1(1, 2) d, respectively, which was markedly shorter than that in group C [(25±10) h, 21(19, 27) h and 3(2, 3) d] (all P<0.01). Overall, the postoperative length of hospital stay reduced significantly for patients who followed the ERAS protocol [7(5, 11) d vs 10(7, 14) d, P<0.01]. The incidence of postoperative complications was 17.8% (8/45) and 37.8% (17/45) in group E and group C, respectively, with a significant difference (P<0.05). Conclusion: Implementation of ERAS anesthesia management in gynecologic oncology patients undergoing minimally invasive surgery alleviates perioperative discomfort, decreases surgical stress response, and improves the early postoperative quality of recovery.

Abstract
BACKGROUND Visceral function localization of the brain is very complex. For many years, people have been actively exploring the neural mechanism regulating visceral and substance metabolism, clarifying the complex relationship between the brain and peripheral nervous system related to the regulation of visceral activity, and analyzing its complex neural pathways. The brain is the advanced center of visceral function regulation. As an advanced center for substance metabolism and visceral regulation, the hippocampus is crucial for regulating visceral function. The liver is the core organ of material metabolism, and its afferent signals are mainly projected to the Nucleus of the solitary tract(NTS) through vagus nerve, and then they are projected to the hypothalamus and limbic system. MATERIALS AND METHODS We placed a stereotaxic instrument on the head of each rat and performed craniotomy to open a window above the left hippocampus. We used gold-plated tungsten electrodes to monitor hippocampal neuronal discharges. Grounding was achieved using screws and silver wire. We electrically stimulated the liver branch of the vagus nerve and observed changes in hippocampal neuron discharges using a biological method; in this way, we identified hepatosensitive hippocampal region. We injected FluoroGold into this region and related brain areas. After 3 days, the rats were sacrificed and perfused; the hippocampi were fixed, dehydated, frozen, sectioned, and subjected to fluorescence microscopy. RESULTS Nerve discharge frequency and amplitude significantly increased in the hippocampal CA3 region (AP: -4.9, ML: -5.1, DV: -5.0 mm). After FluoroGold was injected into the left hepatosensitive region in the hippocampus, labeled cells were found in the contralateral hippocampus, ipsilateral piriform cortex (PC), locus coeruleus (LC) and bilateral lateral hypothalamus (LHA); fluorescence in the ipsilateral hypothalamus was stronger than that of the contralateral hypothalamus. FluoroGold was injected into the LHA, PC, and LC; no labeled cells were found in the hippocampal CA3 region or in the control group. CONCLUSIONS The hippocampal CA3 area of rats may contain a hepatosensitive region that plays important roles in the regulation of liver and other organ function. These region may receive input from the LHA, PC, and LC.

Abstract
A new α-emitting isotope ^{214}U, produced by the fusion-evaporation reaction ^{182}W(^{36}Ar,4n)^{214}U, was identified by employing the gas-filled recoil separator SHANS and the recoil-α correlation technique. More precise α-decay properties of even-even nuclei ^{216,218}U were also measured in the reactions of ^{40}Ar, ^{40}Ca beams with ^{180,182,184}W targets. By combining the experimental data, improved α-decay reduced widths δ^{2} for the even-even Po-Pu nuclei in the vicinity of the magic neutron number N=126 are deduced. Their systematic trends are discussed in terms of the N_{p}N_{n} scheme in order to study the influence of proton-neutron interaction on α decay in this region of nuclei. It is strikingly found that the reduced widths of ^{214,216}U are significantly enhanced by a factor of two as compared with the N_{p}N_{n} systematics for the 84≤Z≤90 and N<126 even-even nuclei. The abnormal enhancement is interpreted by the strong monopole interaction between the valence protons and neutrons occupying the π1f_{7/2} and ν1f_{5/2} spin-orbit partner orbits, which is supported by the large-scale shell model calculation.

Abstract
Objective: To evaluate the effect of the pessary treatment on general anxiety disorder in patients with symptomatic pelvic organ prolapse (POP). Methods: Between December 2018 and January 2020, 213 patients who received the pessary treatment for symptomatic POP in the Peking Union Medical College Hospital (PUMCH) were enrolled in this prospective observational study. Accepting the pessary successfully means that the patient keeping the pessary for 2 weeks were satisfied with it and willing to use it afterwards, or means that the patient having changed a new pessary and keeping it for 2 weeks were satisfied with it and willing to use it afterwards. The questionnaire General Anxiety Disorder-7 (GAD-7) was used to assess the anxiety state of POP patients, including 163 patients who accepted the pessary treatment successfully and 50 patients who failed, before and after the pessary treatment. A score of 10 or more was considered as the moderate or severe anxiety and defined as the anxiety disorder. Patients who accepted the pessary treatment successfully were followed up for 3 months. Results: Before the treatment, the prevalence of anxiety disorders was 20.9% (34 out of 163) for those patients accepting the pessary and that was 20.0% (10 out of 50) for those patients who failed in keeping the pessary, the difference of which were not statistically significant (P=0.896). The difference of demographic data and clinical characteristics between the anxiety disorder group and the non-anxiety disorder group were not statistically significant (P>0.05). After 3 months of the pessary treatment for those patients using the pessary treatment, the prevalence of anxiety disorders dropped to 3.7% (6/163) from 20.9% (P<0.001). The GAD-7 score of patients with anxiety disorders decreased from a median of 16.0 (12.5, 21.0) before the treatment to 1.0 (0, 4.0) after the treatment, and the difference was statistically significant (P<0.001). Conclusion: Around 20% POP patients receiving pessary treatment had the moderate or severe general anxiety disorder. After 3 months of using the pessary treatment, the prevalence of anxiety disorders in POP patients had dropped significantly.
