Abstract
OBJECTIVE To explore the association between postpartum depression (PPD) and transforming growth factor-β (TGF-β) concentrations in human colostrum. METHODS Participants were recruited from a maternal and infant cohort established in a tertiary general hospital in Guangdong Province between December, 2020 and September, 2021. In the afternoon of the second postpartum day, the women were evaluated with Edinburgh Postnatal Depression Scale (EPDS) for screening PPD (defined as a score of 10 or higher). The women with PPD were matched at a 1:1 ratio with women without PPD with maternal age difference within 5 years and the same mode of delivery. Colostrum samples were collected in morning on the third postpartum day for measurement of TGF-β concentrations using enzyme-linked immunosorbent assay (ELISA), and the association between EPDS scores and TGF-β concentrations was analyzed in the two groups. RESULTS A total of 90 women were included in the final analysis. The mean concentrations of TGF-β1, TGF-β2 and TGF-β3 in the colostrum were 684.03 (321.22-859.25) pg/mL, 5116.50±1747.04 pg/mL and 147.84±48.68 pg/mL in women with PPD, respectively, as compared with 745.67 (596.00-964.22) pg/mL, 4912.40±1516.80 pg/mL, and 168.21±48.15 pg/mL in women without PPD, respectively. Compared with women without PPD, the women with PPD had significantly lower concentrations of TGF-β1 (P=0.026) and TGF-β3 (P=0.049) in the colostrum. Spearman correlation analysis revealed that the EPDS scores were negatively associated with the concentrations of TGF-β1 (r=-0.23, P=0.03) and TGF-β3 (r=-0.25, P=0.02) in the colostrum. CONCLUSION PPD is associated with decreased concentrations of TGF-β1 and TGF-β3 in human colostrum, suggesting the need of early PPD screening and interventions during pregnancy and the perinatal period to minimize the impact of PPD on human milk compositions.

Abstract
OBJECTIVE Using claims data from an integrated payer-provider, we compared the costs incurred by insulin-dependent diabetes mellitus (IDDM) patients who received Hospital Inpatient/Observation/Emergency Department care (HIghER care) for diabetes-related events with those who did not receive such care to identify a target population for interventions in future studies. METHODS A retrospective study pooled real-world claims data for IDDM with type 1 or type 2 DM between July 1, 2018 and June 30, 2019. Medical claims were used to calculate the total and diabetes-related allowed medical costs to the Enterprise and per-member per month (pmpm) costs. RESULTS A total of 19,378 members' medical and prescription drug coverage were analyzed. Only 8.4% of the IDDM population received HIghER care but incurred 20% of medical expenses, and nearly 40% of diabetes-related medical costs. For HIghER care patients, medical spending was higher in every inpatient and outpatient category (Wilcoxon two sample tests, all p < 0.0001). Non-diabetes related prescription drug costs were greater in this group (Wilcoxon, Z = 2.2879, p = 0.0221), but diabetes-related prescription drug costs were higher for non-HIghER care (Wilcoxon, Z = -9.5918, p < 0.0001). In a longitudinal study of 29,602 patients over 24 months, prior-year receipt of HIghER care was a significant predictor of HIghER care the subsequent year (odds ratio 3.28) CONCLUSIONS: Medical spending for HIghER care patients was disproportionately high and greater in every inpatient and outpatient category. Receipt of HIghER care in the previous year was highly predictive of HIghER care episodes the following year.

Abstract
Objective: To explore the clinical value of mismatch negativity and P3a combined with electroencephalogram (EEG) reactivity to predict the prognosis of patients after severe brain injury. Methods: The clinical data of patients with severe brain injury who were admitted to the neurosurgical intensive care unit of Xiangya Hospital of Central South University from October 2019 to July 2020 were retrospectively analyzed. All patients underwent evaluation of auditory mismatch negativity (MMN), P3a, and EEG reactivity (EEG-R) within 28 days after the onset of coma. Patients were divided into two groups using the 3-month Glasgow Outcome Scale (GOS) after coma onset, a GOS score of 3-5 was defined as a favorable outcome, and GOS grades 1-2 were defined as an unfavorable outcome. The correlation between clinical indicators and prognosis was analyzed, and the predictive values of statistically significant indicators and the cut-off values were determined using the receiver operating characteristic (ROC) curve. Results: A total of 48 patients were enrolled in the study, including 35 males and 13 females (age range:18-68 years old). Twenty-nine of the patients had a favorable outcome and 19 had an unfavorable outcome. The Glasgow Coma Scale (GCS), EEG-R, absolute amplitude of MMN at Fz (FzMMNA), and amplitude of P3a at Cz (CzP3aA) were significantly correlated with the prognosis of comatose patients (P<0.001). Multivariate logistic regression analysis revealed that only EEG-R, FzMMNA, and CzP3aA were independent predictors for the prognosis of comatose patients after severe brain injury (all P<0.05), with the area under the curve (AUC) of 0.757 (0.613-0.900), 0.912 (0.830-0.994) and 0.887 (0.793-0.981), respectively. The combination of FzMMNA and CzP3aA and the combinationof EEG-R, FzMMNA and CzP3aA increased the value of AUC to 0.942 (0.879-1.000) and 0.964 (0.920-1.000), respectively. Moreover, a cut-off value of 1.27 μV and 2.64 μV for FzMMNA and CzP3aA, respectively, yielded the best sensitivity and specificity for the prognosis prediction of patients with severe brain injury [FzMMNA: 89.66%(26/29) and 84.21%(16/19); CzP3aA:82.76%(24/29) and 84.21%(16/19)]. Conclusion: This study indicates that the combination of EEG-R, FzMMNA, and CzP3aA may serve as a favorable prognostic indicator for comatose patients after severe brain injury.

Abstract
Ductal origin of distal pulmonary artery (DODPA) is a rare congenital cardiovascular anomaly, with an incidence of approximately 1 in 200 000 people. It involves the proximal interruption of one pulmonary artery branch, with the distal part arising from the base of the brachiocephalic artery, via the ipsilateral ductus arteriosus (DA) and the intrapulmonary branch of the pulmonary artery is usually intact. If timely treatment is not provided after birth, it is very likely that, due to DA closure, severe hypoplasia will occur in the lung supplied by the abnormal pulmonary artery. Hence, prenatal diagnosis of DODPA is important to enable initiation of prostaglandin treatment and early rehabilitation of the affected lung. Herein, we report three cases of fetal DODPA diagnosed via two-dimensional (2D) ultrasonography combined with four-dimensional (4D) spatiotemporal image correlation. We also present a literature review, and explore the ultrasonographic findings and the importance of 2D and 4D ultrasonography in obtaining an accurate prenatal diagnosis of DODPA. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
This Letter reports the first measurement of high-energy reactor antineutrinos at Daya Bay, with nearly 9000 inverse beta decay candidates in the prompt energy region of 8-12 MeV observed over 1958 days of data collection. A multivariate analysis is used to separate 2500 signal events from background statistically. The hypothesis of no reactor antineutrinos with neutrino energy above 10 MeV is rejected with a significance of 6.2 standard deviations. A 29% antineutrino flux deficit in the prompt energy region of 8-11 MeV is observed compared to a recent model prediction. We provide the unfolded antineutrino spectrum above 7 MeV as a data-based reference for other experiments. This result provides the first direct observation of the production of antineutrinos from several high-Q_{β} isotopes in commercial reactors.

Abstract
AIM To explore the value of preoperative contrast-enhanced computed tomography (CT) tumour texture characteristics, and clinical and laboratory parameters on the prognosis of curative resection for non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS This retrospective study included 64 patients (34 men and 30 women) with NSCLC who underwent curative resection and were then followed up for 5 years or until death. Preoperative contrast-enhanced CT images, clinical features, and laboratory parameters were collected for these patients. CT texture features of the primary tumour before surgery were extracted from the contrast-enhanced CT images using ImageJ software. Based on the cut-off values determined by X-tile software, the preoperative CT texture features, clinical features, and laboratory parameters were divided into two groups. Kaplan-Meier survival curves and log-rank tests were used to compare the 5-year overall survival (OS) of patients. Multivariate Cox regression analysis was used to determine the independent factors influencing the prognosis. RESULTS The mean survival was 51.5 months. Tumour volume, entropy, platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), and albumin-to-globulin ratio (AGR) were shown to be significantly associated with 5-year OS (p<0.05). Multivariate Cox regression analysis revealed that entropy was the independent factor of prognosis (hazard ratio 4.375, 95% confidence interval [CI]: 1.646-11.620, p=0.003). CONCLUSION Entropy is an important and potentially non-invasive imaging biomarker for predicting the prognosis of NSCLC undergoing curative resection.

Abstract
BACKGROUND No standard of care for mucosal melanoma (MM) in the adjuvant setting has been established. Meanwhile, relapse-free survival (RFS) is only about five months after surgery alone. This phase II trial aimed to compare toripalimab vs. high-dose interferon-α2b (HDI) as an adjuvant therapy for resected MM. PATIENTS AND METHODS From July 2017 to May 2019, 145 patients with resected MM were randomized (1:1) to receive HDI (N = 72) or toripalimab (N = 73) for one year until disease relapse/distant metastasis, unacceptable toxicity, or withdrawal of consent. The primary endpoint was RFS. The secondary endpoints included distant metastasis-free survival (DMFS), overall survival (OS), and safety. RESULTS After a median follow-up of 26.3 months, the numbers of RFS, OS, and DMFS events were 51 vs. 46, 33 vs. 29, and 49 vs. 44 in the toripalimab arm and the HDI arm, respectively. The median RFS were 13.6 (95%CI: 8.31-19.02) months and 13.9 (95%CI: 8.28-19.61) months in the toripalimab arm and HDI arm, respectively. The DMFS was not significantly different between the two arms (HR: 1.00, 95%CI: 0.65-1.54). The median OS was 35.1 months (95%CI: 27.93-NR) in the toripalimab arm, with no significant difference in all-cause death (HR: 1.11, 95% CI: 0.66-1.84) for the two arms. The median sums of the patients' actual infusion doses were 3672 mg and 1054.5 MIU in the toripalimab arm and HDI arm, respectively. The incidence of treatment-emergent adverse events with a grade ≥ 3 was much higher in the HDI arm than in the toripalimab arm (87.5% vs. 27.4%). CONCLUSION Toripalimab showed a similar RFS and a more favorable safety profile than HDI, both better than historical data, suggesting that toripalimab might be the better treatment option. However, additional translational studies and better treatment regimens are still warranted to improve the clinical outcome of MM.

Abstract
Abstract
Study question
The impact of endometriosis on the outcomes of ART is still ambiguous and the mechanism by which endometriosis impacts fertility has not been fully elucidated
Summary answer
Endometriosis was associated with low CLBR in IVF, which might be due to the change of follicular microenvironment and compromising the quality of embryos.
What is known already
Despite the great advantages of IVF treatment in endometriosis-linked infertility, the impact of endometriosis on outcomes of infertility management with ART is controversial and few studies focused on the association between endometriosis and CLBR. Numerous mechanisms have been proposed in an effort to delineate the multifaceted pathophysiology that induces impairment of reproductive dynamics in patients with endometriosis. Reactive oxygen species, dysregulation of the immune system and cellular architectural disruption constitute the crucial mechanisms that detrimentally affect oocyte and embryo developmental potential.
Study design, size, duration
This study retrospectively included 433 patients with endometriosis and 1299 patients with tuber factor infertility to evaluate the impact of endometriosis on IVF pregnancy outcome between January 2016 and December 2018.The basic study prospectively recruited 30 patients with ovarian endometriosis and 35 controls with tubal factor infertility to analyze polarization stage of macrophages in their follicular fluid, and another 20 females with ovarian endometriosis and 30 controls to detect cytokines in their FF.
Participants/materials, setting, methods
Data on all women undergoing fresh or frozen IVF treatment cycles were analysed to compare the CLBR between endometriosis and tuber factor infertility patients. A cytometry panel of 4 antibodies (CD45, CD3, CD80, CD163) was designed to enumerate the numbers of MI and MII macrophages from the cell sediment from FF samples. Quantibody® array was utilized to determine the concentration of 10 cytokines in FF, including IFN-γ, IL-1α, IL-1β, IL-10,IL-13,IL-4, IL-6, IL-8, MCP-1 and TNF-α.
Main results and the role of chance
The results showed that patients with endometriosis were associated with noticeably fewer retrievable oocytes, a lower oocyte maturity rate, decreased numbers of available and high-quality embryos (all p < 0.001) in comparison with the control group. The clinical pregnancy and live birth rate of the endometriosis group were lower in the frozen-thawed embryo transfer cycles (p = 0.028 and p = 0.008, respectively), which leading to a declined cumulative live birth rate (CLBR) (p = 0.001). Logistic regression analysis indicated a close association between endometriosis and low CLBR (p = 0.002). Furthermore, the numbers of type I and type II macrophages in follicular fluid (FF) of patients with ovarian endometriosis were significantly increased compared with the control group (p < 0.001). The expressions of IL-1α, IL-1β, TNF-α, IL-6, IL-13, and IL-10 in FF were higher in endometrioma group(p < 0.05). The increased expression of cytokines was negatively correlated with embryo outcomes, including the numbers of total oocytes retrieved, mature oocytes, and fertilized oocytes, and the numbers of high-quality blastocysts and embryos. Additionally, IL-6 and IL-8 were positively correlated with AMH, rate of available blastocysts, number of blastocysts formed and available blastocysts, but were negatively associated with rate of MII oocytes.
Limitations, reasons for caution
The present study being of a retrospective and monocentric study, may not come to a very convincing conclusion, and some unknown biases might still exist due to possible underestimation of some confounders.
Wider implications of the findings
Collectively, our results indicate that endometriosis does adversely affect pregnancy outcomes of ART, as women with endometriosis produce a lower quantity of oocytes and embryos. Moreover, endometriosis might play a role in oocyte or embryo outcomes via regulating the production of cytokines or the number of immune cells in FF.

Abstract
OBJECTIVE We aimed to systematically review the impact of local estrogen use in combination with a pessary on vaginal complications in postmenopausal women with pelvic organ prolapse (POP). METHODS We searched databases including Medline, Embase, PubMed, Clinical Trials and the Cochrane Central Register of Controlled Trials for relevant literature published in English from inception to 31 May 2021. Only randomized controlled trials (RCTs) and cohort studies were included. RESULTS In total, five studies were included (three RCTs, one prospective study and one retrospective cohort study). The meta-analysis was performed with subgroups. Our results indicated a significantly lower incidence of bacterial vaginosis (BV) among postmenopausal women who used estrogen than among controls, with a total pooled odds ratio (OR) of 0.29 (95% confidence interval [CI]: 0.11-0.72; I2 = 38%; p = 0.008). The summary ORs of the estrogen use group were 0.98 (95% CI: 0.59-1.63; I2 = 41%; p = 0.95) for vaginal ulceration, 0.80 (95% CI: 0.42-1.54; I2 = 29%; p = 0.50) for vaginal bleeding and 0.74 (95% CI: 0.35-1.58; I2 = 35%; p = 0.44) for vaginal discharge. CONCLUSIONS Local estrogen in combination with a pessary could decrease the BV rate among postmenopausal women with POP. However, consensus regarding the value of estrogen use for decreasing other pessary complications has not yet been reached. Additional multicenter RCTs with large sample sizes should be conducted to better understand the effect of estrogen use on reducing pessary-related complications.

Abstract
Objective: To understand the incidence of pneumoconiosis in the non-coal mining industry in Jiangsu Province, and provide reference for the prevention and control of pneumoconiosis in the non-coal mining industry. Methods: The data of 7019 newly diagnosed pneumoconiosis patients in non-coal mining industry in Jiangsu Province from January 1956 to December 2019 were collected through the Jiangsu Province Pneumoconiosis Follow-up Network Report System, including the gender of the pneumoconiosis patients, the name of the employer and the location, the industry classification of the employer, the duration of dust exposure in dust exposure, the name of occupational pneumoconiosis disease, the date of diagnosis of pneumoconiosis, etc. The collected case data of patients with pneumoconiosis were entered into the statistical software, and the characteristics of the patients' diagnosis time, region and industry were analyzed. Results: The number of confirmed pneumoconiosis patients in the non-coal mining industry in Jiangsu Province was mostly in 2007 (395 cases) , concentrated in Wuxi City (40.96%, 2875/7019) and Suzhou City (27.72%, 1946/7019) . The industries to which the patients belonged were mainly non-metallic mining and dressing (60.95%, 4278/7019) , and the most common type of pneumoconiosis was silicosis (96.40%, 6766/7019) . The patients were mainly stageⅠpneumoconiosis (61.33%, 4305/7019) . There were statistically significant differences in the mean age of diagnosis and the average duration of dust exposure among patients with different pneumoconiosis stages (P<0.01) . The differences in the average diagnosis age and the average duration of dust exposure of patients with different types of pneumoconiosis were statistically significant (P<0.05) , the mean age of diagnosis and the average duration of dust exposure of electric welders were the smallest, which were (44.92±7.74) years old and (17.38±10.15) years, respectively. Conclusion: The regional and industry distribution characteristics of new pneumoconiosis patients in the non-coal mining industry in Jiangsu Province are obvious, and attention should be paid to the treatment of pneumoconiosis patients with young diagnosed age and short duration of dust exposure, as well as the personal protection and health protection of front-line workers such as electric welders who are exposed to productive dust in a short period of time.

Abstract
Objective: To explore the feasibility and perioperative safety of transoral robotic surgery with da Vinci Xi platform for pharyngolaryngeal tumors. Methods: A retrospective analysis was performed on 55 consecutive cases with resection of pharyngolaryngeal tumors by transoral robotic surgery with da Vinci Xi platform from July 27, 2020 to October 31, 2021 in the Department of Head and Neck Surgery, Fudan University Eye, Ear, Nose and Throat Hospital, including 44 males and 11 females, aged 25-79 years. There were 41 cases of oropharyngeal tumors, 9 cases of parapharyngeal space tumors, 2 cases of laryngeal tumors, 2 cases of hypopharyngeal tumors and 1 case of retropharyngeal space tumor. Operative time, intraoperative blood loss, postoperative hospital stay, perioperative tracheotomy, nasal feeding, hemorrhage and other complications were analyzed. Results: Of the 55 patients, 54 received resection of pharyngolaryngeal tumors by da Vinci robot through oral approach, and only 1 case of pyriform sinus carcinoma underwent a conversion to open surgery due to poor exposure of lower margin. The average surgical time for the patients with transoral robotic surgeries was 64.4 min, the average blood loss was 24.8 ml, the average postoperative hospital stay was 6.9 d, and the average oral feeding time was 11.1 d. Seventeen patients (30.9%) underwent preventive tracheotomy during surgery. Among 38 cases of laryngeal cancer, 28 underwent simultaneously neck dissection. No serious complications occurred in all patients during and after operation. The follow-up time was 1-15 months. Aside from 1 patient had a relapse 10 months after surgery, other patients had no recurrence or metastasis. Conclusion: Transoral robotic surgery with da Vinci Xi is safe, effective and minimally invasive for resection of pharyngolaryngeal tumors under reasonable indications.

Abstract
Realizing quantum speedup for practically relevant, computationally hard problems is a central challenge in quantum information science. Using Rydberg atom arrays with up to 289 qubits in two spatial dimensions, we experimentally investigate quantum algorithms for solving the Maximum Independent Set problem. We use a hardware-efficient encoding associated with Rydberg blockade, realize closed-loop optimization to test several variational algorithms, and subsequently apply them to systematically explore a class of graphs with programmable connectivity. We find the problem hardness is controlled by the solution degeneracy and number of local minima, and experimentally benchmark the quantum algorithm's performance against classical simulated annealing. On the hardest graphs, we observe a superlinear quantum speedup in finding exact solutions in the deep circuit regime and analyze its origins.

Abstract
Objective: To understand the characteristics and trend of the premature death rate of 4 major chronic diseases in Ji'nan from 2015 to 2020. Methods: The death cause surveillance data and population data during 2015-2020 in Ji'nan were collected, and abbreviated life table, Joinpoint regression analysis and other methods were used to analyze the characteristics and change trends of the premature death rates of 4 major chronic diseases. Results: The crude mortality rate and age standardized mortality rate changes for the 4 major chronic diseases from 2015 to 2020 range from 568.65/100 000 to 604.06/100 000 and 366.77/100 000 to 432.48/100 000, respectively. The annual premature death rate of 4 major chronic diseases declined by 3.33% averagely from 2015 to 2020 (95%CI: -6.25%--0.32%), which might be explained by the declines of the premature death rates of cardiovascular and cerebrovascular diseases [average annual percentage change (AAPC)=-3.23%, 95%CI: -6.32%--0.05%] and cancer (AAPC=-3.58%,95%CI:-6.83%--0.21%). The average decline rate in women (AAPC=-4.19%,95%CI:-7.56%- -0.70%) was higher than that in men (AAPC=-2.92%,95%CI: -5.65%--0.11%). Conclusions: The premature death rate of 4 major chronic diseases showed a downward trend in Ji'nan from 2015 to 2020. Men should be considered as a key population in the prevention and control of 4 major chronic diseases, and attention should also be paid to the non-significant declines in the premature death rates of chronic respiratory diseases and diabetes.

Abstract
A joint determination of the reactor antineutrino spectra resulting from the fission of ^{235}U and ^{239}Pu has been carried out by the Daya Bay and PROSPECT Collaborations. This Letter reports the level of consistency of ^{235}U spectrum measurements from the two experiments and presents new results from a joint analysis of both data sets. The measurements are found to be consistent. The combined analysis reduces the degeneracy between the dominant ^{235}U and ^{239}Pu isotopes and improves the uncertainty of the ^{235}U spectral shape to about 3%. The ^{235}U and ^{239}Pu antineutrino energy spectra are unfolded from the jointly deconvolved reactor spectra using the Wiener-SVD unfolding method, providing a data-based reference for other reactor antineutrino experiments and other applications. This is the first measurement of the ^{235}U and ^{239}Pu spectra based on the combination of experiments at low- and highly enriched uranium reactors.

Abstract
Artificial liver is one of the effective methods to treat liver failure. Patients with liver failure are critically ill and have great individualized differences. Therefore, the specific program for the treatment of liver failure with artificial liver should be individualized. The commonly used non-biological artificial liver models include simple plasmapheresis, double filtration plasmapheresis, plasma filtration with dialysis, double plasma molecular adsorption system, molecular absorbent recirculating system, hemodiafiltration, continuous venovenous hemodiafiltration, hybrid, etc. The curative effect should be properly judged from patient's symptoms, laboratory test indicators, survival rate and other aspects after artificial liver therapy.

Abstract
Objective: To study the clinicopathological and genetic features of natural killer (NK)-cell enteropathy for better understanding of this rare disease and prevention of its misdiagnosis. Methods: Two cases of NK-cell enteropathy were diagnosed in the First Affiliated Hospital of Zhengzhou University, China from October 2017 to February 2021. The clinical characteristics, morphology, immunohistochemistry, Epstein-Barr virus-encoded RNA (EBER) in situ hybridization and T cell receptor gene rearrangement were analyzed. The patients were followed up by a telephone interview. Results: The patients were both male, aged 40 and 28 years, respectively. Both patients were admitted to the hospital for an annual checkup without obvious gastrointestinal symptoms. The endoscopy showed that the gastric body of case 1 had a mucosal bulge, small area of congestion and erosion, while the rectum of case 2 had congestion and erosion. Microscopically, the lesions of the 2 cases were relatively limited. Many lymphoid cells infiltrated within the lamina propria of the mucosa and into the muscularis mucosa in case 2. In case 1, the glands were reduced in the lesion, and the glandular cavity was slightly compressed and deformed. There was no infiltration or destruction of the glands in either case. Lymphoid cells were atypical, with medium-to-large cell sizes. Their cytoplasm was medium-to-slightly abundant and appeared eosinophilic or translucent. In case 2, characteristic eosinophilic granules were seen in the cytoplasm of a few cells. The nuclei in both cases were round, oval and irregular, with fine chromatin, inconspicuous nucleoli, and no mitotic figures were noted. Necrosis was seen in case 1 while both cases had no central growth or destruction of blood vessels. Immunophenotyping showed that CD56, granzyme B and TIA-1 were positive in both cases, part of the cells was CD3-positive, and some cells were weakly CD4-positive in case 2. The CD5, CD8, CD30, ALK and B-lineage markers (CD20, CD79α) were all negative. The Ki-67 proliferation index was about 60% and 30%, respectively. Both cases were EBER negative. TCR gene rearrangement was polyclonal. Follow-up showed that none of the 2 patients had any special treatments and stayed well. Conclusions: NK-cell enteropathy is rare, with biological behaviors similar to benign tumors, and occasional recurrence. Its histology and immunophenotype are easily confused with NK/T cell-derived lymphomas. Combination of its unique endoscopic features, EBER negativity, polyclonal TCR gene rearrangement and good prognosis can confirm the diagnosis and avoid misdiagnosis and overtreatment.

Abstract
Objective: To investigate the survival outcomes and prognostic factors of patients with salvage surgery for hypopharyngeal carcinoma after radiotherapy. Methods: A retrospective analysis was performed, including 26 patients treated in Ningbo Medical Center Lihuili Hospital between January 2010 and December 2015. All patients were males, aged 48-83 years, of whom 8 cases were local residual after radiotherapy alone, 8 cases were local recurrence after postoperative radiotherapy, 2 cases were residual of cervical lymph nodes after radiotherapy alone, 2 cases were recurrence of cervical lymph nodes after radiotherapy alone, 2 cases were recurrence of cervical lymph nodes after postoperative radiotherapy and 4 cases were recurrence of tracheal stoma. The salvage operations included: local resection, local resection with neck dissection, simple neck dissection, tumor resection of tracheostomy, and additional repair according to the defect. Chi square test was used for recurrence and metastasis analysis, Kaplan-Meier method for survival analysis, Log-rank test for univariate analysis, and Cox regression model for multivariate analysis. Results: The complication rate of salvage surgery was 23.1% (6/26). The recurrence rate was 65.4% (17/26) and the distant metastasis rate was 42.3% (11/26) in the 5-year follow-up after salvage surgery. Patient's age and tumor invasion extent were correlated with recurrence. Initial treatment, tumor persistence or recurrence after radiotherapy, recurrence location and tumor invasion extent were correlated with distant metastasis (all P<0.05). Overall, 3 year and 5 year survival rates were 42.3% and 23.1% respectively. Age, recurrence location, surgical margin and tumor invasion extent were related to prognosis (χ²=6.56, 10.68, 9.32, and 7.90 respectively, all P<0.05). Multivariate analysis showed that surgical margin and tumor invasion extent were independent risk factors for prognosis (OR (95%CI) = 3.19 (1.03-9.84), 14.37 (2.46-84.08), both P<0.05). Conclusion: Salvage surgery is the first choice for patients with recurrence after radiotherapy for hypopharyngeal carcinoma. Safe surgical margin should be ensured, especially in tumors invading muscle, bone tissue or lymph node capsule.

Abstract
RATIONALE Stereoisomer profiling is always a difficult issue. Based on the difference between diastereomers, usually because of steric hindrance, isomers can be differentiated by mass spectrometry (MS), although it is often not an easy task. In the current study, tetracycline, chlortetracycline and doxycycline could be distinguished from their respective 4-epimers by MS. METHODS The electrospray ionization tandem mass spectrometry (ESI-MSn ) analyses were carried out on a Bruker 3000plus ion trap mass spectrometer. For MS/MS experiments, the collision energy was set between 0.18 and 0.45 V to perform energy-resolved mass spectrometry (ERMS). Test solutions were prepared in methanol/water (90:10, v/v) at a concentration of 10 μg/mL. RESULTS Compared with the collision-induced dissociation (CID) spectrum of protonated tetracycline, the most abundant peak changed from m/z 427 to m/z 410 for 4-epitetracycline. For chlortetracycline and its 4-epimer, differences in relative abundance were observed too. In the CID spectrum of a fragment ion of doxycycline, the abundance of m/z 154 was relatively higher than for the 4-epimer, showing the same trend as in the CID spectra of the other two pairs of tetracyclines. CONCLUSIONS The CID spectra of tetracycline and chlortetracycline were different from those of their 4-epimers. The CID spectra of protonated doxycycline and its 4-epimer showed only a subtle difference, but the m/z 154 fragment ion in the CID spectra of the fragment ion at m/z 428 offers the possibility to differentiate both epimers.

Abstract
OBJECTIVE To evaluate the performance of FibroTouch in combination with four hepatic fibrosis biomarkers for assessment of the degree of hepatic fibrosis among patients with chronic schistosomiasis-induced liver disorders. METHODS A total of 63 patients with chronic schistosomiasis-induced liver diseases admitted to The Third People's Hospital of Kunshan City from January to March 2021 were enrolled as the observation group, while 50 healthy volunteers receiving health examinations in the hospital during the study period were randomly selected as the control group. The liver stiffness measurement (LSM) was determined using the FibroTouch technique, and the serum levels of four hepatic fibrosis biomarkers were detected using chemilumi-nescence immunoassay, including type IV collagen (IV-C), type III procollagen (PC-III), hyaluronidase (HA) and laminin (LN). The receiver operating characteristic (ROC) curves of LSM and four hepatic fibrosis biomarkers alone and in combination for assessing the degree of hepatic fibrosis among patients with chronic schistosomiasis-induced liver disorders were plotted and the area under the ROC curve (AUC) was estimated to examine the value of LSM and four hepatic fibrosis biomarkers alone and in combination for assessing the degree of hepatic fibrosis. RESULTS There were 63 subjects in the observation group, including 28 men and 35 women, and the participants had a mean age of (65.34 ± 12.56) years and a mean body mass index (BMI) of (24.47 ± 11.05) kg/m2. There were 50 subjects in the control group, including 22 men and 28 women, and the participants had a mean age of (64.28 ± 13.10) years and a mean BMI of (25.12 ± 11.64) kg/m2. There were no significant differences between the observation and control groups in terms of gender ratio (χ2 = 0.002, P > 0.05), age (t = 0.437, P > 0.05) or BMI (t = 0.303, P > 0.05). The LSM [(8.65 ± 5.22) vs. (3.24 ± 1.10) kPa; t = 8.013, P < 0.05], IV-C [(51.80 ± 9.45) vs. (30.10 ± 10.34) ng/L; t = 11.506, P < 0.05], PC-III [(77.28 ± 17.22) vs. (48.62 ± 9.54) ng/L; t = 11.224, P < 0.05], HA [(39.55 ± 5.32) vs. (84.89 ± 10.34) ng/L; t = 30.158, P < 0.05] and LN [(99.47 ± 7.37) vs. (61.93 ± 9.80) ng/L; t = 22.496, P < 0.05] were significantly greater in the observation group than in the control group, and Spearman correlation analysis showed that the degree of liver fibrosis positively correlated with LSM (rs = 0.675, P < 0.01), IV-C (rs = 0.421, P < 0.01), PC-III (rs = 0.517, P < 0.01), HA (rs = 0.550, P < 0.01) and LN (rs = 0.539, P < 0.01) among patients with chronic schistosomiasis-induced liver diseases. ROC curve analysis revealed that the AUC of LSM for assessment of the hepatic fibrosis degree was 0.884 (P < 0.001), and the LSM cutoff, sensitivity and specificity were 11.75 kPa, 71.43% and 84.00% at the highest Youden index, respectively. In addition, the AUC of four hepatic fibrosis biomarkers for assessment of the hepatic fibrosis degree was 0.577 to 0.670, with 70.174 to 115.237 ng/L cutoff values, 17.46% to 68.25% sensitivity and 71.01% to 96.00% specificity. In addition, the sensitivity and specificity of LSM combined with four hepatic fibrosis biomarkers were 92.06% and 95.07% for assessment of the hepatic fibrosis degree among patients with chronic schistosomiasis-induced liver diseases. CONCLUSIONS FibroTouch in combination with detection of four hepatic fibrosis biomarkers has a high sensitivity and specificity for assessing the degree of hepatic fibrosis among patients with chronic schistosomiasis-induced liver diseases, which deserves widespread clinical uses.

Abstract
Objective: To analyze the efficacy and safety of toripalimab combined with axitinib in the treatment of advanced renal cell carcinoma. Methods: Clinical data of 50 patients with advanced renal cell carcinoma who received axitinib combined with toripalimab were retrospectively collected from the database of Peking University Cancer Hospital. ORR, DCR, PFS, and OS were analyzed. Results: Among the 50 patients, 37 were males; median age was 56 (22-73) years; 38 were pathologically diagnosed as clear cell renal cell carcinoma and 12 were non-clear cell carcinoma. Common metastatic sites included lung, bone, lymph node, liver, and so on. 90% of the patients had received at least one-line of systemic therapy. With a median follow-up time of 11.9 months (0.8-24), 27 of the 50 patients are still on treatment, ORR was 34%, DCR was 86%, median PFS was 13.1 months (95%CI 5.8-20.4), and median OS has not yet reached. One-year OS rate was 84.6%. Common adverse reactions were proteinuria, diarrhea, hypertension, abnormal thyroid function, elevated transaminase, and hand-foot syndrome. Most adverse events were grade 1-2. Conclusion: Toripalimab combined with axitinib was efficient in the treatment of advanced renal cell carcinoma, and had manageable adverse reactions.

Abstract
Microvascular compression of the trigeminal root entry zone (TREZ) is the main cause of most primary trigeminal neuralgia (TN), change of glial plasticity was previously studied in the TREZ of TN rat model induced by chronic compression. To better understand the role of astrocytes and immune cells in the TREZ, different cell markers including glial fibrillary acidic protein (GFAP), complement C3, S100A10, CD45, CD11b, glutamate-aspartate transporter (GLAST), Iba-1 and TMEM119 were used in the TN rat model by immunohistochemistry and flow cytometry. On the post operation day 28, GFAP/C3-positive A1 astrocytes and GFAP/S100A10-positive A2 astrocytes were activated in the TREZ after compression injury, there were no statistical differences in the ratios of A1/A2 astrocytes between the sham and TN groups. There was no significant difference in Iba-1-positive cells between the two groups. The ratios of infiltrating lymphocytes (CD45+CD11b−) (p = 0.0075) and infiltrating macrophages (CD45highCD11b+) (p = 0.0388) were significantly higher than those of the sham group. In conclusion, different subtypes A1/A2 astrocytes in the TREZ were activated after compression injury, infiltrating macrophages and lymphocytes increased, these neuroimmune cells in the TREZ may participate in the pathogenesis of TN rat model.

Abstract
Endometrial cancer (EC) is the fourth most common malignancy in women in developed countries. The prognosis of EC is extremely poor, and it is an important factor that contributes to the death of patients. Therefore, studying EC pathogenesis and therapeutic targets, and exploring effective drugs are the primary tasks to improve the prognosis of EC. In the present study, we aimed to explore the function of ginkgolic acid (GA) in EC cell apoptosis and autophagy through PI3K/Akt/mTOR signal pathway in vitro and in vivo. Firstly, MTT assay and clone formation assay were employed to analyze the Ishikawa and HEC-1-B cell viabilities and proliferation after treatment with GA. The results showed that GA inhibited endometrial cancer cell survival. Flow cytometry assay and western blot assay were applied to examine the apoptosis and apoptosis related protein Bcl-2, Bax, Cleaved caspase-3 expression levels of Ishikawa and HEC-1-B cells after treatment with GA. Next, we applied western blot assay to analyze the autophagy associated proteins LC3I, LC3II, p62 and Beclin-1 in GA treated Ishikawa and HEC-1-B cells. We found that GA promoted apoptosis and induced autophagy of endometrial cancer cells. Meanwhile, western blot assay was also used to determine the expression levels of the PI3K/Akt/mTOR signal pathway related protein and the results revealed that GA inhibited the activity of PI3K/Akt/mTOR pathway. Finally, we found that GA inhibited tumor growth in vivo through immunohistochemistry assay. In conclusion, GA induces apoptosis and autophagy of EC cells via inhibiting PI3K/Akt/mTOR pathway in vivo and vitro.

Abstract
Recovery from exercise refers to the period between the end of a bout of exercise and the subsequent return to a resting or recovered state. It is a dynamic period in which many physiological changes occur. A large amount of research has evaluated the effect of training on intramuscular lipid metabolism. However, data are limited regarding intramuscular lipid metabolism during the recovery period. In this study, lipid metabolism-related proteins were examined after a single bout of exercise in a time-dependent way to explore the mechanism of how exercise induces intramuscular lipid metabolism adaptation. Firstly, all rats in the exercise group underwent a five-week training protocol (HIIT, five times/week), and then performed a more intense HIIT session after 72 h of the last-time five-week training. After that, rats were sampled in a time-dependent way, including 0 h, 6 h, 12 h, 24 h, 48 h, 72 h, and 96 h following the acute training session. Our results discovered that five weeks of HIIT increased the content of intramuscular triglyceride (IMTG) and enhanced the lipolytic and lipogenesis-related proteins in skeletal muscle. Furthermore, IMTG content decreased immediately post HIIT and gradually increased to baseline levels 48 h postexercise, continuing to over-recover up to 96 h postexercise. Following acute exercise, lipolytic-related proteins showed an initial increase (6-12 h) before decreasing during recovery. Conversely, lipogenesis-related proteins decreased following exercise (6-12 h), then increased in the recovery period. Based on the changes, we speculate that skeletal muscle is predominated by lipid oxidative at the first 12 h postexercise. After this period, lipid synthesis-related proteins increased, which may be the result of body recovery. Together, these results may provide insight into how the lipid metabolism-related signaling changes after chronic and acute HIIT and how protein levels lipid metabolism correlates to IMTG recovery.

Abstract
Occupational disease diagnosis standards are an important basis for occupational disease diagnosis, occupational health surveillance, occupational health supervision, occupational disease treatment, occupational disease disability assessment, and handling of occupational disease diagnosis disputes in conjunction with the "Occupational Disease Prevention and Control Law of the People's Republic of China". With the successive promulgation of the "Standardization Law of the People's Republic of China" and the "Administrative Measures on Health Standards", the establishment of a mandatory standard implementation evaluation mechanism has gradually been paid attention to. However, there is still a lack of systematic research on the evaluation of diagnostic criteria for occupational diseases. Therefore, this article combines the current status of the diagnostic standards for occupational diseases in China, and proposes reasonable suggestions on how to carry out the evaluation of the implementation of this type of standard in terms of evaluation methods and content.

Abstract
Background Gingival enlargement (GE) is one of the most common soft tissue problems encountered during fixed orthodontic treatment. Aims: This study aimed to evaluate the factors affecting GE in adolescents and young adults, compared with their normal peers. Subjects and Methods This is a cross-sectional comparative study. The sample consisted of 329 subjects (ages 10-30 years) of both genders, which was divided into four main groups: The control group (G0) with no orthodontic treatment; subjects who underwent orthodontic treatment were divided according to treatment duration into G1 (4-12 months), G2 (13-24 months), and G3 (>24 months). The clinical examinations included the level of debris, calculus (simplified oral hygiene), and GE indices. Regression analyses were used to assess the GE association in all the studied groups. Results The mean GE score increased significantly with increased treatment duration (0.42 ± 0.29 for G0 and 1.03 ± 0.52 for G3). GE scores of the lower arch were significantly higher in the anterior segment than in the posterior segment among all treatment groups. Regression analysis revealed that gender, age, oral hygiene, and treatment duration had a significant effect on GE (P < 0.05), while angle classification, overjet, overbite, treatment stage, bracket type, and therapeutic extraction did not show significant associations (P > 0.05). Conclusion Gender, age, oral hygiene, and treatment duration were the most important risk factors for GE during fixed orthodontic treatment.

Abstract
Objective: To analyze the clinical effect of extracorporeal membrane oxygenation (ECMO) in the treatment of burn patients with acute respiratory distress syndrome (ARDS). Methods: The retrospective observational study and the systematic review were applied. From March 2014 to July 2020, five burn patients with ARDS received ECMO treatment in the First Affiliated Hospital of Army Medical University (the Third Military Medical University). All the five patients were male, aged from 40 to 62 years. The average total burn surface area was 58.8% total body surface area (TBSA) and four cases had severe inhalation injury. Patient's ECMO starting time, duration and mode, and whether successfully weaned or the cause of death, and others. were recorded. Furthermore, the changes of oxygenation and infection before, during, and after utilizing ECMO were analyzed. PubMed and Web of Science from the establishment of each database to August 2021 were searched using "Extracorporeal Membrane Oxygenation", "ECMO", "burn", "inhalation" as the search terms and "Title/Abstract" as the field to retrieve the clinical articles that meet the selection criteria . Basic information were extracted from the articles, including sample size, gender, age, total burn area, inhalation injury, the indication of ECMO, the start and lasting time of ECMO, ECMO mode, rate of successful weaning, complications of ECMO, mortality, the combined application of continuous renal replacement therapy (CRRT). Results: Five patients started venovenous ECMO on an average of 10.2 days after injury and lasted an average of 180.4 hours. Three out of 5 patients were weaned successfully with one patient survived. Four patients died of multiple organ dysfunction syndrome (MODS) and septic shock. Compared with those before ECMO treatment, the arterial oxygen partial pressure (PaO2) and oxygen saturation in arterial blood (SaO2) of three successfully weaned patients obviously increased during and after ECMO treatment. The fraction of inspired oxygen (FiO2) decreased below 50% and PaO2/FiO2 ratio increased above 200 mmHg (1 mmHg=0.133 kPa) during and after ECMO. Furthermore, lactic acid and respiratory rate decreased, basically. Compared with those before ECMO, PaO2 and SaO2 in the other two patients during ECMO, who failed to be weaned, continuously decreased while lactic acid increased. Before and during ECMO, the PaO2/FiO2 ratios of unsuccessfullg weaned cases were less than 200 mmHg, and partial pressure of carbon dioxide in arterial blood (PaCO2) were more than 40 mmHg. Compared with those before ECMO, there were no significant changes in body temperature during and after ECMO, which were less than 38 ℃. Compared with those before ECMO, the leucocyte number (the index without this in unsuccessfully weaned cases was omitted, the same as below) in four patients showed a significant decrease during ECMO, but rose after removal of ECMO. The proportion of neutrophils in three patients were slightly higher during ECMO than before ECMO, and did not change significantly after removal of ECMO. Compared with those before ECMO, platelet counts in three patients were significantly reduced during ECMO, and all five patients during ECMO were below normal levels. Compared with those before ECMO, the procalcitonin levels in four deaths were significantly increased during ECMO. Catheter culture of microorganism was performed in three successfully weaned patients, all of which were negative. A total of 13 literature were included, ranging from 1990 to 2019. The sample size in 6 studies was less than 10, and the sample size in 4 studies was between 10 and 20, and only 2 literatures had a sample size larger than 50. ECMO was applied in 295 burn patients with overall mortality of 48.8% (144/295), including 157 adults and 138 children. The most common indication of ECMO was severe ARDS. Among 157 adult burn patients (95 males and 65 females), 36 cases had inhalation injury. The average burn area was 27%-37%TBSA in 5 reported studies and was more than 50%TBSA in 2 reported studies. The most common mode was venovenous ECMO. ECMO treatment began 26.5 hours to 7.4 days after injury and lasted from 90 hours to 18 days, and the rate of successful weaning ranged from 50% to 100%. The most common complications were bleeding and infection. The mortality was 52.9% (83/157). MODS and sepsis were the leading causes of death. Among 138 pediatric burn patients (77 boys and 61 girls), 29 patients had inhalation injury. The average burn area was 17%-50.2%TBSA in 3 studies. ECMO treatment lasted from 165.2 hours to 324.4 hours. Bleeding was the most common complication. The mortality was 44.2% (61/138). Conclusions: ECMO is an effective strategy for the salvage treatment of burns complicated with ARDS. Furthermore, the prevention and treatment of bleeding, infection and organ dysfunction should be emphasized during the use of ECMO. More importantly, evidence-based guidelines for burns are urgently needed to further improve the clinical effect of ECMO.

Abstract
Oroxylum indicum is one of the valuable Dai pharmaceuticals; the dry seeds and bark of O. indicum were used to treat acute cough, sore throat and so on. Of the seven compounds from O. indicum were determined and obtained using the bioassay-guided method. Among them, compound 7 was obtained from the plant for the first time. Eight bacterial strains and one yeast fungi were exposed to the compounds. Minimum inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs) or minimum fungicidal concentrations were determined according to the standard broth microdilution method. Baicalein (2) exhibited relative strong antibacterial activities with MIC of 8 μg ml-1 and MBC of 16 μg ml-1 against three MRSA strains of Staphylococcus aureus of SCCmec III type, whereas flavonoids 3, 5 and 7 showed some degree of activities against methicillin-susceptible S. aureus (MSSA, ATCC 25923). The findings may offer new evidence that why O. indicum was used widely in Dai peoples' life.

Abstract
BACKGROUND Postinflammatory hyperpigmentation (PIH) is a common, acquired pigmentary disorder of the skin associated with significant quality-of-life impairment, especially in individuals with skin of colour. Current treatment for PIH is limited, largely due to a poor understanding of disease pathogenesis and the lack of a representative disease model. OBJECTIVES This study is intended to further develop, update and validate our previously designed in vivo model of acne-induced PIH/postinflammatory erythema (PIE) using different concentrations of trichloroacetic acid (TCA), a medium-depth chemical peel. METHODS Twenty-nine patients with skin types II-VI and clinician-confirmed presence of two or more truncal acne pustules and PIH/PIE were included. On the basis of Investigator's Global Assessment (IGA), clinical polarized photography (CPP), colorimetry and Skindex, we experimentally determined an optimum TCA concentration and assessed our model's ability to exhibit a dose-response relationship between degree of inciting insult and severity of resulting pigmentation. We also performed differential microRNA profiling and pathway analysis to explore the potential of microRNAs as molecular adjuncts to our model. RESULTS Application of TCA 30% produced lesions indistinguishable from acne-induced PIH and PIE lesions on the basis of colorimetry data without causing epidermal necrosis. Application of progressively increasing TCA doses from 20% to 30% resulted in concentration-dependent increases in CPP, IGA and colorimetry scores at all timepoints during the study. miRNA-31 and miRNA-23b may play a role in PIH pathogenesis, although further validation is required. CONCLUSIONS Our TCA-based in vivo model, using TCA concentrations between 20% and 30% with an optimum of 30%, enables the quantitative assessment of the pigmentary response to varying degrees of cutaneous inflammation in a fashion that mirrors natural acne-induced PIH and PIE.

Abstract
Objective: To explore related factors associated with unilateral aldosterone secretion of patients with primary aldosteronism (PA) and construct a predictive model. Methods: The clinical data of patients who were diagnosed as PA in West China Hospital from April 2016 to September 2020 was analyzed retrospectively. According to the results of the adrenal enhancement CT, patients were divided into 3 groups, namely non-nodular group with no bilateral adrenal glands lesions, only with unilateral adrenal hyperplasia or bilateral adrenal hyperplasia, unilateral nodule group with unilateral adrenal nodules and the contralateral adrenal glands with hyperplasia or not, and bilateral nodules group with nodules in both adrenal glands. Regarding the related factors of dominant side of aldosterone secretion, univariate analysis and binary logistic regression were used. Receiver operating characteristic curve and nomogram were used to evaluate the diagnostic performance of regression models. Results: A total of 237 patients with PA were included, of which, 118 males and 119 females, the median age was 39 years, and the body mass index (BMI) was (25.2±3.5) kg/m2. There were 157 (66.2%) of 237 patients with typical imaging findings. There were 32 cases in no-nodular group, 183 cases in unilateral nodule group, and 22 cases in bilateral nodules group. Multivariate analysis showed that age (OR=0.876, P<0.001), blood potassium concentration (OR=0.430, P=0.004), and typical imaging findings (OR=2.202, P=0.035) were associated with unilateral aldosterone secretion. As for unilateral nodule group, multivariate analysis showed that age (OR=0.900, P<0.001), plasma aldosteronism concentration (PAC) (OR=1.050, P=0.018), and typical imaging findings (OR=2.637, P=0.025) were associated with unilateral aldosterone secretion. The agreement rate between the dominant side of the adrenal CT and AVS was only 50.2%. Multivariate analysis showed that age (OR=0.954, P=0.001), BMI (OR=0.893, P=0.024) and PAC (OR=1.043, P=0.011) were independently associated with concordance between AVS and CT. The cut-off value of the ROC curve was 0.43; the model sensitivity was 56.3%; the specificity was 86.7% and the area under the ROC curve was 0.742. Conclusions: Age is an important predictor in the diagnosis of PA subtypes. It is recommended to refer to subgroup based on imaging results for clinical decision. For patients with no obvious lesions or bilateral lesions on CT, AVS should be performed as far as possible to confirm the subtypes in diagnosis of PA.

Abstract
OBJECTIVE To explore the expression characteristics of ELK3 and its role in the occurrence, progression and prognosis of gastric cancer. METHODS We analyzed the expression characteristics of ELK3 in gastric cancer based on E-MTAB-6693 dataset and explored the prognostic value of ELK3 using Kaplan-Meier survival analysis and univariate and multivariate Cox regression analysis. Chip-Atlas, ChipBase, Genes Transcription Regulation Database, and hTFtarget were used for predicting the target genes of ELK3 and constructing the transcription regulation network. Functional enrichment analysis of the target genes was performed using R software. The proportions of infiltrating immune cells in gastric cancer were analyzed using Cibersort tool, and the Pearson coefficients between ELK3 and these cells were calculated. The expression profile of ELK3 was verified based on Gene Expression Profiling Interactive Analysis and Human Protein Atlas databases. We also collected 5 pairs of gastric cancer and adjacent tissue samples and detected the expression of ELK3 at both the mRNA and protein levels using RT-PCR and Western blotting. RESULTS In public datasets and clinical samples, ELK3 was highly expressed in gastric cancer (P < 0.05), and its expression increased with the progression of M stage, AJCC stage, and perineural invasion (P < 0.05). ELK3 expression was correlated with N stage, AJCC stage, Lauren classification, differentiation, pathological classification, and microsatellite status of gastric cancer (P < 0.05). A high expression of ELK3 was associated with significantly reduced overall survival and disease-free survival of the patients, and served as an independent prognostic factor of gastric cancer (P < 0.05). Comprehensive analysis identified 176 potential target genes of ELK3, and enrichment analysis showed that ELK3 may regulate Rap1, AMPK, chemokines, VEGF, TNF, and tumor PD-L1/PD-1 signaling (PP < 0.05). The expression of ELK3 was negatively correlated with regulatory T cells, follicular helper T cells, and CD8+T cells in gastric cancer (P < 0.05). CONCLUSION ELK3 acts as an oncogene in gastric cancer, and its high expression may promote the occurrence, progression and immune escape of gastric cancer.

Abstract
OBJECTIVE To explore whether procyanidin B2 (PCB2) regulates the P13K/Akt/Nrf2 signaling pathway to protect neurons from oxidative stress induced by cypermethrin (CYP). METHODS Primary cultures of cerebral cortex neurons from C57BL/6 mice were randomly divided into 5 groups: normal control group (cultured in serum-free neurobasal-B27 medium), PCB2 treatment group(treated with 5 μg/mL PCB2 for 24 h), CYP exposure group(treated with 50 μmol/L CYP for 24 h), PCB2 pretreatment group(pretreated with 5 μg/mL PCB2 for 30 min followed by exposure to 50 μmol/L CYP for 24 h), and LY294002 treatment group (pretreated with 20 μmol/L LY294002 for 30 min before treatment with PCB2 for 30 min and then CYP for 24 h).CCK-8 assay was used to analyze the neuronal viability after the treatments.Reactive oxygen species (ROS) production in the cells was detected using the fluorescent probe DCFH-DA and flow cytometry.The changes in nuclear morphology and mitochondrial membrane potential of the cells were examined with Hoechst 33342 and JC-1 staining, respectively.Western blotting was performed to detect the protein expressions of Nrf2, HO-1, p-Akt and Akt in the cells. RESULTS In CYP exposure group, the cells showed significantly decreased viability and mitochondrial membrane potential with obvious apoptotic morphological changes and abnormal ROS production.By comparison, the cells in PCB2 preconditioning group showed improved cell survival rate, reduced abnormalities in nuclear morphology, increased mitochondrial membrane potential, and lowered intracellular ROS production.CYP exposure caused Nrf2 nuclear translocation and up-regulated Nrf2, HO-1, p-Akt protein expressions in the cells, which were inhibited by PCB2 pretreatment.Inhibition of the P13K/Akt signaling pathway obviously neutralized the protective effect of PCB2 against CYP-induced neuronal injury. CONCLUSIONS PCB2 regulates the Nrf2/ARE signaling pathway by activating the P13K/Akt signaling pathway to protect mouse cerebral cortical neurons against oxidative injury induced by cypermethrin.

Abstract
The dominance effect is a kind of non-additive effect due to the interaction between alleles at the same locus. Quantitative traits such as growth traits in farm animals have been found to be influenced by dominance effects. However, dominance effects are usually ignored in the genome-wide association study (GWAS) of complex traits for farm animals. In this study, we performed GWAS and genetic parameters estimation for the two traits age at 100 kg (AGE) and backfat thickness at 100 kg (BF) of 3572 Large White pigs. The pigs were from three breeding farms of China and were genotyped by an in-house designed 50k SNP chip. Our results showed significant non-zero variance for the dominance effect of AGE, while the dominance effect of BF was not significant. Using a GWAS model accounting for both additive and dominance effects, we identified three additive and two dominance significant SNPs for the trait AGE. For the trait BF, three genome-wide significant additive SNPs were detected, but no significant SNP was found for the dominance effect. In total, six important functional genes (NPAS3, USP16, PARN, ARL15, GPC3, ABHD4) near significant SNPs were identified as candidate genes associated with AGE or BF. Notably, ARL15 and PARN were associated with AGE near the dominance association signals. Overall, the newly detected SNPs and newly identified candidate genes in our study added new information about the genetic architectures of growth and fatness traits in pigs, and have the potential to be applied to the pig breeding program in the future.

Abstract
Abstract
Study question
Is it safe using aspirin (A) and prednisone (P) before pregnancy among women with antithyroid antibodies (ATAbs) undergoing assisted reproductive technology?
Summary answer
Combination therapy of aspirin and prednisone didn’t improve likelihood of clinical pregnancy, but increased miscarriage rate.
What is known already
Compared with women with negative-ATAb, women with positive-ATAb had a lower live birth rate and a higher miscarriage rate. Insufficient evidence existed to determine whether aspirin and prednisone therapy improved the success of pregnancy following assisted reproductive technology (ART) in ATAb-positive euthyroid women. Aspirin and prednisone were used frequently in clinical practice, but the use of these medicines before pregnancy during ART process is still controversial, and the risks of these medicines were not well understood.
Study design, size, duration
A prospective study involving 268 women with unexplained reason for infertility who tested positive for antithyroperoxidase antibody (TPOAb) and/or thyroglobulin antibody (TgAb) were being treated for infertility at the Second Affiliated Hospital of Zhejiang University School of Medicine, Ningbo Women and Children’s Hospital and People’s Hospital of Jinhua from October 2017 to July 2020. Their TSH level ranged from 0.35–4.0mIU/ml and they all underwent fresh embryo transfer.
Participants/materials, setting, methods
Overall, a total of 268 ATAb-positive women were divided 2 groups: group A: no treatment; B: A+P. Both medicines were used in the lowest effective dose. Between the two groups, we measured oocytes retrieved, fertilization rate, high-quality embryo rate, blastulation rate, cleavage rate,implantation rate, likelihood of clinical pregnancy and miscarriage rate. Kruskal-Wallis test was used in nonnormally distributed variables, and the χ2 test or Fisher exact test was used to compare categorical variables.
Main results and the role of chance
A total of 268 infertile women with unexplained reason who tested positive for TPOAb and/or TgAb were recruited in our study. According to assignment, they were divided into two groups. All women in different groups had the similar age, BMI, number of miscarriage and duration of infertility. Levels of FSH, AMH, TSH, FT4, FT3, fibrinogen and d-dimer were similar in all groups. The use of A+P reduced cleavage rate (F = 23.982, P < 0.001) and implantation rate (F = 4.388, P = 0.036). The fertilization rate (P = 0.407), high-quality embryo rate (P = 0.208) and blastulation rate (P = 0.157) were not influenced by the use of medication. In this study, likelihood of clinical pregnancy (P = 0.066) did not change significantly after therapy, and miscarriage rate (P = 0.042) increased after medical treatment.
Limitations, reasons for caution
Firstly, Aspirin is just one representation of anticoagulation therapy, so additional consideration of low molecular heparin should also be considered. Secondly, further randomized controlled trials of aspirin and prednisone alone are needed.
Wider implications of the findings: In this study, use of A+P showed no positive effect, and reduced cleavage rate and implantation rate, while increased miscarriage rate. So, the use of medication for interfile women should be cautious.

Abstract
OBJECTIVE The acceleration of population aging has brought an unprecedented impact on China's health system. This study is designed to examine the association between depressive symptoms and activity of daily living disability among the elderly in China. STUDY DESIGN This is a cross-sectional study. METHODS Data were drawn from the China Health and Retirement Longitudinal Study (CHARLS). The 10-item Center for Epidemiologic Studies-Depression (CES-D) scale was used to access depressive symptoms, and physical function was assessed by the Activity of Daily Living (ADL) scale. Multivariate logistic regression was used to assess the association between depressive symptoms and ADL among the elderly. RESULTS Based on a sample of 5863 elderly people over 60 years old, our results showed that 1999 elderly people are with depressive symptoms, accounting for 34.1%. The mean score of ADL among the elderly with depressive symptoms (20.65 ± 7.14) was much higher than that in those without depressive symptoms (17.40 ± 4.87). After controlling potential confounders, multivariate logistic regression showed that ADL and its specific domains including personal care, transfer, medical care, household, and managing money were associated with depressive symptoms. CONCLUSION This cross-sectional study provides evidence of the association between depressive symptoms and ADL disability among the Chinese elderly. As a result, prevention or reduction of ADL disability may have a positive effect on the medical care of the elderly with depressive symptoms.
