Abstract
OBJECTIVE The aim of this study was to clarify the minimum number of examined lymph nodes (MNELNs) required to ensure the quality of lymph node detection and its impact on long-term survival in distal pancreatectomy for pancreatic ductal adenocarcinoma. METHODS Clinicopathological characteristics and survival data of patients with resectable pancreatic cancer who underwent distal pancreatectomy between 2004 and 2017 were collected from the Surveillance, Epidemiology, and End Results database. The associations between the number of examined lymph nodes (ELNs) and number of positive lymph nodes (PLNs), stage migration, and overall survival were investigated through adjusted multivariate models with locally weighted scatterplot smoothing smoothing fitting curves and estimation of the structural breakpoints. Kaplan-Meier survival analysis and X-tile software were used to identify the ideal cut-off value for ELNs. RESULTS In total, 2610 consecutive patients who underwent distal pancreatectomy between 2004 and 2017 were included in this study. The optimal ELN count according to the associations between the number of ELNs and number of PLNs, odds ratio for stage migration, or hazard ratio for overall survival were 19, 17, and 19, respectively. Furthermore, the optimal division of ELN count for maximum overall survival was divided into three populations (ELN ≤ 8, ELN 9-18, ELN ≥ 19) based on X-tile software. CONCLUSION A minimal count of 19 lymph nodes was demanded to guarantee the quality of lymph node examination in patients with distal pancreatectomy. Long-term survival could be delimited by MNELNs. A sufficient number of ELNs could improve the accuracy of cancer staging and reflect a better overall survival.

Abstract
Global warming results in high temperature stress (HTS), which presents severe challenges worldwide for modern agricultural production and will have significant impacts on the yield and quality of crops. Accumulation of photosynthetic products, activity of enzymes involved in sucrose-starch metabolism, phytohormone levels and metabolic profiling using LC-MS were analysed in the flag leaves and/or developing grains subjected to HTS during the grain-filling stage of an indica rice. HTS induced significant yield loss and reduced the grain quality, with lower amylose content. HTS reduced photosynthetic product accumulation in flag leaves and reduced starch accumulation in developing grains, compared to growth under normal temperatures. The activity of enzymes related to sucrose-starch metabolism were dis-regulated in developing grains grown under high temperature (HT). Moreover, phytohormone homeostasis in flag leaves and developing grains was also dramatically disturbed by HT. Metabolic profiling detected many metabolites with remarkably different relative fold abundances at different time points in the developing grain at HT versus normal temperatures, these metabolites were enriched in several HTS response pathways. The change in phytohormone ratio and auxin level might be associated with the reduction in photosynthetic products and their translocation, and ultimately with reduced starch accumulation in the developing grain. The detected metabolites might have different roles in response to the HTS in developing grain at different development stages. These results provide a theoretical reference and basis for future rice production towards higher quality and yield when grown under HTS.

Abstract
Objective: To conclude the clinical features and the postoperative efficacy of congenital middle ear malformation treated with Malleostapedotomy (MS), and to explore the security and effectiveness of MS surgery. Methods: The clinical data of 17 patients (18 ears) with congenital middle ear malformation undergoing MS procedure were analyzed. There were 10 males (11 ears) and 7 females (7 ears), aged from 7 to 48 years. The imaging examination, pure-tone audiometry, intraoperative findings and postoperative hearing improvement of these patients were analyzed and summarized, and software SPSS23.0 was used for statistical analysis. Rusults All the 17 patients (18 ears) presented with hearing loss since childhood on the affected sides. Preoperative high resolution CT (HRCT) of the temporal bone revealed definite malformations in 9 ears (6 ears with incus long process dysplasia and 3 ears with anterior and posterior crus dysplasia). Before surgery, the mean bone conductive hearing threshold at 500, 1 000, 2 000 and 4 000 Hz was (15.6±10.2) dB HL, the mean air conductive hearing threshold was (60.6±9.7) dB HL, and the mean air-bone gap was (45.0±8.9) dB. During the surgery, all 18 ears were found to be accompanied by absence or hypoplasia of incus long process. 12 ears had stapes fixation, 6 ears had oval window atresia. All patients were treated with MS procedure by using Piston. The patients were followed up for 3 months to 1 year. The mean bone conductive hearing threshold was (14.7±8.8) dB HL. The mean air conductive hearing threshold was (37.7±11.6) dB HL, and the mean air-bone gap was (23.0±8.0) dB. There were statistically significant differences in the mean air conductive hearing threshold and mean air-bone gap before and after surgery (P<0.05). While there were no statistically significant differences in the mean bone conductive hearing threshold before and after surgery (P=0.550). Conclusions: MS procedure is safe and reliable in patients with congenital middle ear malformation of incus long process dysplasia, stapes fixation or oval window atresia. HRCT is useful in evaluating the major deformity of ossicular chain and facial nerve deformity. However, it is not enough to evaluate the joint of incus-stapes and oval window atresia. MS surgery in middle ear malformation requires advanced surgical experience and skills. The hearing improvement can be significant, even though some air-bone gap after surgery exist.

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
APOL1 encodes a secreted high-density lipoprotein, which has been considered as an aberrantly expressed gene in multiple cancers. Nevertheless, the role of APOL1 in the regulatory mechanisms of pancreatic cancer remains unknown and should be explored. We identified APOL1 was abnormally elevated in human pancreatic cancer tissues compared with that in adjacent tissues and was associated with poor prognosis. The effects of APOL1 in PC cell proliferation, cell cycle, and apoptosis was verified via functional in vitro and in vivo experiments. The results showed that knockdown of APOL1 significantly inhibited the proliferation and promoted apoptosis of pancreatic cancer. In addition, we identified APOL1 could be a regulator of NOTCH1 signaling pathway using bioinformatics tools, qRT-PCR, dual-luciferase reporter assay, and western blotting. In summary, APOL1 could function as an oncogene to promote proliferation and inhibit apoptosis through activating NOTCH1 signaling pathway expression in pancreatic cancer; therefore, it may act as a novel therapeutic target for pancreatic cancer.

Abstract
Objective: To analyze the cause of late postoperative opacification of hydrophilic acrylic intraocular lenses (IOLs) and the effect of IOL replacement surgery. Methods: This retrospective case series study comprised 15 eyes of 15 patients who were diagnosed as late postoperative opacification of hydrophilic acrylic IOLs from January 2019 to June 2020 at Qingdao Eye Hospital of Shandong First Medical University. The clinical data of patients were reviewed, and two IOLs were examined by scanning electron microscopy and energy dispersive X-ray spectroscopy. The intraoperative and postoperative complications of IOL replacement surgery were evaluated, and best corrected visual acuity was compared before and after surgery. Preoperative and postoperative data were compared using the paired t test. Results: The interval between the first IOL implantation and the detection of IOL opacification in 15 patients was (27.3±5.9) months. All the 15 patients had unilateral IOL opacification, and 9 patients had hypertension. Glycosylated hemoglobin A1c was significantly higher than the normal value in 4 of the 10 patients who underwent cataract surgery at our hospital. Confocal microscopy disclosed coralliform deposits on the superficial IOL optic. Scanning electron microscopy and energy dispersive X-ray spectroscopy showed the presence of calcium and phosphorus crystals in the opacification region of IOLs. Visual acuity in all 13 eyes receiving IOL exchange was significantly improved from 1.03±0.64 (logarithm of the minimum angle of resolution) to 0.39±0.21 (P<0.05). Posterior capsule rupture (4 eyes), new IOL implanted in the ciliary sulcus (3 eyes) and zonule breaking (1 eye) occurred during IOL replacement. Conclusions: IOL opacification is related with the IOL material and calcium ion concentration on the IOL surface. IOL replacement surgery can improve visual acuity safely and effectively.

Abstract
OBJECTIVE To explore the potential factors that affect the accuracy of endoscopic diagnosis for Japan narrow-band imaging (NBI) Expert Team (JNET) type 2B colorectal lesions. OBJECTIVE The clinical data were collected from 261 patients with JNET type 2B colorectal lesions diagnosed in Nanfang Hospital between July, 2018 and July, 2021. We analyzed the macroscopic type, size, location or pit pattern classification of the lesions for their potential influence of the diagnostic accuracy of JNET type 2B lesions. OBJECTIVE The 261 lesions included 91 low-grade intramucosal neoplasia lesions (34.9%), 132 high-grade intramucosal neoplasia lesions (50.6%), 13 submucosal invasive cancer lesions (5.0%), and 25 deep submucosal invasive cancer lesions (9.6%). The coincidence rate between endoscopic prediction and pathological diagnosis of these lesions was 55.6% (145/ 261). The macroscopic type and size of the lesions were significantly associated with the diagnostic accuracy of JNET type 2B lesions (P < 0.001). There was a significant difference in the diagnostic accuracy among the lesions with different pit pattern types (P < 0.001). OBJECTIVE Both the macroscopic type and size affect the accuracy of endoscopic diagnosis of JNET type 2B colorectal lesions. JNET classification combined with pit pattern types can have better accuracy in predicting the pathological diagnosis of these lesions.

Abstract
OBJECTIVE This study aims to evaluate the changes in left ventricular diastolic function after coronary artery bypass grafting through tissue Doppler imaging (TDI) and N-terminal pro-brain natriuretic peptide (NT-proBNP) concentration and the correlation between the two. PATIENTS AND METHODS A total of 133 patients who underwent coronary artery bypass grafting between January 2016 and December 2018 were included in this study. Echocardiography and NT-proBNP concentration were reviewed pre-operation, 1 month post-operation, and 3-6 months post-operation. The transmitral peak flow velocity (E) of the mitral valve was measured at each of the three-time points using spectral Doppler imaging. The mitral annulus displacement (Ea peak and Aa peak) was then measured at each of the time points using TDI, and the E/Ea ratio was calculated. Subsequently, the correlation of the E value, Ea value, and E/Ea ratio with NT-proBNP concentration was statistically analyzed. RESULTS The data obtained at the three-time points were compared with the respective concentrations of NT-proBNP. Multiple linear regression analysis revealed a correlation between NT-proBNP concentration and E value, Ea value, and E/Ea ratio. CONCLUSIONS Left ventricular diastolic function gradually recovered at 1 month and 3-6 months after coronary artery bypass grafting. There was a correlation between TDI-related values and NT-proBNP concentration.

Abstract
Tumor microenvironment comprises of a variety of cell types, which is quite complex and involved in chemotherapy and immune checkpoint blockage resistance. In order to explore the mechanisms involved in tumor immune microenvironment in pancreatic ductal adenocarcinoma (PDAC), we first constructed an immunity-related 18-gene signature using The Cancer Genome Atlas (TCGA) PDAC project data. Then we applied the 18-gene signature to divide PDAC patients into low score and high score groups. Patients in high score group showed inferior prognosis, which was validated in another four independent cohorts, including Ruijin cohort. High score group showed significant enrichment of pathways involved in cell division and cell cycle especially in G1/S phase transition. In high score group, IHC analysis revealed higher levels of the proliferative indexes of Ki67 and PCNA than that in low score group. Prognostic analysis confirmed that patients in high score group could benefit from the gemcitabine-based adjuvant chemotherapy. In low score group, the programmed cell death 1 ligand 1(PD-L1) (+) cases showed worse prognosis but higher T cell infiltration than PD-L1(−) cases. Our immunity-related 18-gene signature could effectively predict PDAC prognosis, and it might be a practical predictive tool to identify PDAC subtype benefitting from gemcitabine-based adjuvant chemotherapy or potentially responding to PD1/PD-L1 blockade therapy.

Abstract
BACKGROUND Several studies have suggested an association between visceral obesity and adverse perioperative outcomes in pancreatic surgery. However, no study has reported the impact of visceral obesity on robotic pancreatic surgery. This study aimed to assess the impact of preoperative visceral obesity on clinically relevant postoperative pancreatic fistula (CR-POPF) in pancreatic ductal adenocarcinoma (PDAC) patients following robotic distal pancreatectomy (RDP) or open distal pancreatectomy (ODP). METHODS A retrospective analysis was performed on all patients who consecutively underwent RDP or ODP for PDAC. The visceral adipose tissue was measured on preoperative computed tomography (CT) images at the L3 vertebra level. A 1:1 propensity score matching method was used in the visceral obesity group and the nonvisceral obesity group to minimize the bias between RDP and ODP. RESULTS Between December 2011 and December 2018, a total of 445 patients were included. Visceral obesity (n = 219) was found to be associated with higher estimated blood loss (p = 0.033), a higher CR-POPF rate (p = 0.001), delayed drain removal (p = 0.005) and a longer length of stay (p = 0.033). In multivariable analysis, visceral obesity was an independent risk factor for CR-POPF (OR: 1.69; 95% CI 1.07-2.67, p = 0.024). Among patients without visceral obesity, the incidence of CR-POPF was lower among RDP than among ODP patients (11.27% vs. 23.87%, p = 0.028), and the difference remained after propensity score matching (9.52% vs. 26.98%, p = 0.011). However, there was no significant difference in the CR-POPF rate between RDP and ODP for visceral obesity patients. CONCLUSION In nonvisceral obesity patients, RDP had better perioperative outcomes than ODP, with a significantly lower CR-POPF rate. However, in visceral obesity patients, RDP showed equivalent CR-POPF rate when compared to ODP.

Abstract
OBJECTIVE Heart failure (HF) is the loss of myocardial structure and function caused by various congenital or acquired heart diseases. This study explored the new target of treatment of HF by investigating the effect of Kallistatin (KS) on inflammation and apoptosis of myocardial tissue in HF rats. MATERIALS AND METHODS We used doxorubicin to induce rat HF, and determined the success rate of modeling by detecting changes in rat heart weight and body weight, cardiac function and histology. We used two different doses (1 mg/kg, 2 mg/kg) of KS intraperitoneally injected rats and detected changes in inflammation and apoptosis of rat myocardial tissue by enzyme-linked immunosorbent assay (ELISA), Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and immunohistochemical staining. Changes in the expression of sirt1 were also detected. In addition, we cultured rat myocardial cell line, H9c2 cells, and used siRNA-sirt1 to inhibit sirt1 in H9c2 cells to clarify the mechanism of KS regulating myocardial cells. RESULTS The body weight of HF rats treated with KS decreased while the heart weight increased. KS has also been found to reduce the concentration of brain natriuretic polypeptide (BNP) in rat serum. The results of echocardiography showed that KS effectively relieved the cardiac function of HF rats. Inflammatory factors (interleukin (IL)-1β, IL-6, IL-8 and tumor necrosis factor (TNF)-α) and pro-apoptotic molecules (caspase3/9 and Bax) in the serum and myocardial tissue of rats treated with KS were also significantly reduced. The inhibition of sirt1 in H9c2 cells significantly reduced the anti-apoptotic effect of KS on H9c2 cells. CONCLUSIONS KS reduces the inflammation and apoptosis of myocardial tissue in HF rats by promoting the expression of sirt1, thereby alleviating HF-induced myocardial injury.

Abstract
OBJECTIVE Nasopharyngeal carcinoma (NPC) is a malignancy and is prone to distant metastasis and radioresistance. Long non-coding RNAs (lncRNAs) play vital roles in human cancers. The purpose of this study was to explore the role and the action mechanism of intergenic lncRNA (LINC00114) in NPC. MATERIALS AND METHODS The expression of LINC00114 and microRNA-203 (miR-203) was measured by quantitative real-time polymerase chain reaction (qRT-PCR). NPC cells were exposed to X-ray as radiation treatment. Cell proliferation, migration, cell survival fraction and apoptosis were assessed by 3-(4, 5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT), transwell, colony formation, and flow cytometry assays, respectively. The expression of Cleaved-cas-3, Cleaved-cas-9, phosphor-ERK (p-ERK) and phosphor-JNK (p-JNK) was quantified by Western blot. The interaction between miR-203 and LINC00114 was predicted by bioinformatics tool microRNA.org and verified by dual-luciferase reporter assay. Tumor formation assay in nude mice was conducted to examine the role of LINC00114 in vivo. RESULTS LINC00114 was upregulated in serums from NPC patients, tissues and cell lines of NPC. LINC00114 knockdown inhibited proliferation, migration, and radioresistance of NPC cells. MiR-203 was a target of LINC00114, and miR-203 inhibition eliminated the effects of LINC00114 knockdown. Besides, the extracellular signal-regulated kinases (ERK)/c-Jun N-terminal kinases (JNK) pathway was inactivated by LINC00114 knockdown but recovered by miR-203 inhibition. Moreover, LINC00114 knockdown suppressed tumor growth and radioresistance in vivo. CONCLUSIONS LINC00114 contributed to NPC development and radioresistance through the regulation of ERK/JNK signaling pathway and the mediation of miR-203, suggesting that LINC00114 was a promising biomarker to defense NPC progression and radioresistance.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal common cancer because of late diagnosis. Novel biomarkers for PDAC early detection are urgently needed. tRNA-derived small RNAs (tsRNAs) are novel small RNAs might serve as biomarkers for cancer diagnosis and participate in diverse physiological and pathological process. We investigated whether the expression of tsRNAs in serum could be a noninvasive method in the early detection of PDAC. Blood sample of PDAC patients and healthy controls were collected from Ruijin Hospital, Shanghai, China. Tumor and adjacent normal pancreas tissues were collected from 51 patients with PDAC undergoing therapeutic surgery. The testing cohort comprised 6 PDAC patients and 6 healthy controls and the expression of small RNAs in serum was analyzed by small RNA sequence. We verified the diagnostic performance of serum tsRNAs by qPCR in validation cohort including 110 PDAC patients and 100 healthy controls. Expression level of tsRNAs in tissue was also verified in another independent cohort including 51 tumor and 51 adjacent normal pancreas tissues. Unpaired t-test and paired t-test are used for comparing depending on whether the samples are paired. The predictive performance of tsRNAs was evaluated by Kaplan-Meier survival and receiver operating characteristic (ROC) curve. There were 45 tsRNAs expressed at remarkably higher levels, 6 tsRNAs expressed at lower levels in PDAC patients, respectively, compared with healthy volunteers. tsRNA-ValTAC-41, tsRNA-MetCAT-37 and tsRNA-ThrTGT-23 expressed significant highly (P < 0.05) in serum of PDAC patients in validation cohort. tsRNA-ValTAC-41 or tsRNA-MetCAT-37 combined with CA19-9 could increase the AUC of PDAC prediction (AUC = 0.947 and 0.949 respectively), relative to CA19-9 test alone. Besides, patients with higher serum tsRNA-ValTAC-41 level showed shorter overall survival (OS). tsRNA-ValTAC-41 also expressed at remarkably higher level in tumor tissue, and it was obviously associated with tumor staging both in serum and tissue. We provide tsRNAs profiles observed by small RNA sequencing. The diagnostic accuracy of tsRNA-ValTAC-41 and tsRNA-MetCAT-37 in serum of PDAC patients were verified. Further studies for tsRNA-ValTAC-41 are needed to confirm the findings. These tsRNAs may be promising and effective candidates in the development of highly sensitive, noninvasive biomarkers for PDAC diagnosis.
