Abstract
The epigenetic modification levels of donor cells directly affect the developmental potential of somatic cell nuclear transfer (SCNT) embryos. BRG1, as an epigenetic modifying enzyme, has not yet been studied in donor cells and SCNT embryos. In this study, BRG1 was overexpressed in porcine fetal fibroblasts (PFFs), its effect on chromatin openness and gene transcription was examined, subsequently, the development potential of porcine SCNT embryos was investigated. The results showed that compared with the control group, the percentage of G1 phase cells was significantly increased (32.3 % ± 0.87 vs 25.7 % ± 0.81, P < 0.05) in the experimental group. The qRT-PCR results showed that the expression of H3K9me3-related genes was significantly decreased (P < 0.05), HAT1 was significantly increased (P < 0.05). Assay of Transposase Accessible Chromatin sequencing (ATAC-seq) results revealed that SMARCA4、NANOG、SOX2、MAP2K6 and HIF1A loci had more open chromatin peaks in the experimental group. The RNA-seq results showed that the upregulated genes were mainly enriched in PI3K/AKT and WNT signaling pathways, and the downregulated genes were largely focused on disease development. Interestingly, the developmental rate of porcine SCNT embryos was improved (27.33 % ± 1.40 vs 17.83 % ± 2.02, P < 0.05), the expression of zygotic gene activation-related genes in 4-cell embryos, and embryonic development-related genes in blastocysts was significantly upregulated in the experimental group (P < 0.05). These results suggest that overexpression of BRG1 in donor cells is benefit for the developmental potential of porcine SCNT embryos.

Abstract
Brahma-related gene 1 (BRG1) enhances the pluripotency of embryonic and adult stem cells, however, its effect on induced pluripotent stem cell (iPSC) pluripotency has not been reported. The aim of this study was to investigate the effect of BRG1 on porcine iPSC pluripotency and its mechanisms. The effect of BRG1 on porcine iPSC pluripotency was explored by positive and negative control it. The mechanism was investigated by regulating the WNT/β-catenin signaling pathway and autophagy flux. The results showed that inhibition of BRG1 decreased pluripotency-related gene expression in porcine iPSCs; while its overexpression had the opposite effect, the expression of WNT/β-catenin signaling pathway- and autophagy-related genes was significantly up-regulated (P < 0.05) in the BRG1 overexpressed group when compared to the control group. Inhibited pluripotency-related gene or protein expression, decreased autophagy flux, and increased mitochondrial length and mitochondrial membrane potential (MMP) were observed when porcine iPSCs were treated with the WNT/β-catenin signaling pathway inhibitor IWR-1. Forced BRG1 expression restored porcine iPSC pluripotency, increased autophagy flux, shortened mitochondria, and reduced MMP. Lastly, Compound C was used to activate porcine iPSC autophagy, and it was found that the expression of BRG1 and β-catenin increased, and pluripotency-related gene and protein expression was up-regulated; these effects were reversed when the BRG1 inhibitor PFI-3 and IWR-1 were added. These results suggested that BRG1 enhanced the pluripotency of porcine iPSCs through WNT/β-catenin and autophagy pathways.

Abstract
Objective: To analyze the classification, diagnosis and treatment status of patients with pulmonary hypertension (PH) in Yunnan province. Methods: This was a retrospective study. Hospitalized patients with PH at Yan'an Affiliated Hospital of Kunming Medical University from January 2012 to December 2019 were enrolled. The clinical data of enrolled patients, including demographic data, comorbidities, targeted drug therapy, echocardiography and right heart catheterization results, were obtained through the electronic medical record system. The composition ratio of PH, diagnosis and treatment were analyzed. Results: A total of 13 590 patients with PH were enrolled, accounting for 3.09% (13 590/440 056) of the total number of hospitalizations during the same period. The composition of PH was predominantly pulmonary arterial hypertension (PAH) (55.50% (7 542/13 590)), followed by pulmonary hypertension (PH) caused by left heart disease (24.16% (3 284/13 590)). Among them, PAH could be subdivided into four types: idiopathic pulmonary arterial hypertension (IPAH), PAH associated with connective tissue disease, PAH associated with portal hypertension, and PAH associated with congenital heart disease (CHD-PAH), with CHD-PAH as the predominating type (98.09% (7 398/7 542). Patients with PAH were predominantly adolescents. In hospitalized patients with PH, from 2012 to 2019, the proportion of children and adolescents showed a decreasing trend from year to year, and the proportion of middle-aged and older adults showed a significant increasing trend, and the proportion of female patients showed a gradual decreasing trend, and the proportion of patients with comorbid hypertension, diabetes mellitus, coronary artery disease, arrhythmia, and pneumonia showed an increasing trend. A total of 1 034 patients (7.61% (1 034/13 590)) underwent right heart catheterization. The concordance rate between echocardiographic and right heart catheterization findings was (86.98% (875/1 006)). A total of 2 574 (18.94%) of PH patients were treated with PAH targeted drugs, of which 58.16% (1 497/2 574) were treated with monotherapy. Among the PH patients treated with PAH targeted drugs, the majority of patients were PAH patients (86.44% (2 225/2 574)), and 83.53% (2 150/2 574) patients treated with PAH targeted drugs were CHD-PAH. Conclusions: Hospitalized PH patients in our center between 2012 and 2019 are predominantly CHD-PAH, and the proportion of patients receiving right heart catheterization and targeted drug therapy is relatively low. The percentage of middle-aged and elderly PH patients shows an increasing trend from year to year, as well as the percentage of those with concomitant comorbidities.

Abstract
Early cleavage (EC) influences the development of the pre-implantation and post-implantation embryo. Symmetric cleavage (Sym) and asymmetric cleavage (Asy) have been observed in EC, but its molecular mechanism remains unclear. This study was designed to pick out the key candidate genes and signaling pathway between Sym and Asy embryos by applying Smart-seq2 technique. In in-vitro fertilization (IVF) 2-cell embryos, Sym embryos and Asy embryos accounted for 62.55% and 37.45%, respectively. The 2-cell rate, blastocyst rate and total blastocyst cells of Sym group were significantly higher than those of Asy group (31.38% vs 18.79%, 47.55% vs 29.5%, 71.33 vs 33.67, P < 0.05). The 2-cell rate, blastocyst rate and total blastocyst cell number in parthenogenetic activation (PA) embryos in Sym group were significantly higher than those in Asy group (40.61% vs 23.64%, 63.15% vs 30.11%, 50.75 vs 40.5, P < 0.05). A total of 216 differentially expressed genes (DEGs) incorporating 147 genes up-regulated and 69 genes down-regulated genes were screened under the p-value <0.05 and |log2 (fold change)| ≥ 1 when compared with Sym group. Further Gene Ontology (GO) analysis showed that these DEGs were related to the regulation of metabolic process, cell cycle, chromosome segregation, centromeric region and microtubule cytoskeleton. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed that the DEGs were mainly enriched to oocyte meiosis, cell cycle, p53 and Hippo signaling pathways. We concluded that asymmetric cleavage is a consequence of altered gene expression. Atg4c, Sesn2, Stk11ip, Slc25a6, Cep19 and Cep55 associated with mitochondrial function and cytoskeletal structure were probably the key candidate genesto determine the zygote cleavage pattern.

Abstract
PURPOSE To explore the prevalence of nocturnal intermittent hypoxemia (NIH) in a tertiary hospital geriatric department and the relationship between NIH and mild cognitive impairment (MCI) in older adults, and to examine the role of brain-derived neurotrophic factor (BDNF) Val66Met polymorphism. METHODS Older adults aged ≥ 60 were enrolled. NIH and cognitive assessments were conducted. BDNF concentrations and BDNF Val66Met polymorphism were detected for a preliminary exploration of the possible mechanism of the process. RESULTS Of 325 older adults enrolled, 157 (48%) had NIH and were further divided into mild, moderate, and severe NIH groups according to their oxygen desaturation of ≥ 4% per hour of sleep (ODI4). MCI detection rate in the four groups gradually increased, and the differences were statistically significant (chi-square = 4.457, P = 0.035). ODI4 was negatively correlated with MoCA score in all participants (r = - 0.115, P = 0.039) and patients with NIH (r = - 0.199, P = 0.012). After adjusting for sex, age, and cardiovascular risk factors, NIH and MCI remained independently associated (OR = 3.13, 95% CI 1.03-9.53, P = 0.045). BDNF levels were positively correlated with MoCA score (r = 0.169, P = 0.028) and negatively correlated with nocturnal average oxygen saturation in patients with NIH (r = - 0.288, P = 0.008). Older adults with different BDNF Val66Met genotypes did not show significant differences in MCI rate and BDNF levels (P > 0.05). CONCLUSION The older adults with NIH have a higher MCI detection rate. BDNF levels may be a potential biomarker for cognitive dysfunction in patients with NIH.

Abstract
BACKGROUND We conducted this animal study to assess the efficacy of the novel hydrogel containing zinc oxide-loaded and minocycline serum albumin nanoparticals (Mino-ZnO@Alb NPs) on peri-implantitis in an experimental mouse model. MATERIAL AND METHODS Mino-ZnO@Alb NPs was prepared as previously reported. The peri-implantitis model was successfully established in rats, and the rats were divided into three groups randomly: Mino-ZnO@Alb NPs (Mino-ZnO) group, minocycline group, and untreated group. Four weeks later, clinical and radiographic assessments were performed to evaluate soft tissue inflammation and bone resorption level. Histologic analysis was performed to estimate the amount of remaining supporting bone tissue (SBT) around implants. ELISA tests were used to determine the concentration of inflammation factor interleukin-1-beta (IL-1β) and anti-inflammation factor tumor necrosis factor-alpha (TNF-α) around implants. RESULTS After one month, the Mino-ZnO group showed better results than the other two groups in regards to the results of bleeding on probing, probing pocket depth, bleeding index and gingival index. X-ray showed that SBT at mesial and distal sites around implants in the other two groups was significantly lower compared with that of Mino-ZnO group. The quantity of osteoclasts in peri-implant tissues of the Mino-ZnO group was less than that in the minocycline and untreated groups. IL-1β in the Mino-ZnO group was lower than that in the other two groups. TNF-α level was the opposite. CONCLUSIONS Mino-ZnO@Alb NPs can effectively treat peri-implantitis and promote soft tissue healing, and may act as a promising product.

Abstract
Objective: To investigate the effect of pretreatment with oral contraceptives (OC) on cumulative clinical pregnancy of oocyte retrieval cycle in polycystic ovary syndrome (PCOS) women with gonadotropin releasing hormone (GnRH) antagonist protocol. Methods: A retrospective cohort study was conducted to analyze PCOS women who underwent in vitro fertilization-embryo transfer (IVF-ET)/intracytoplasmic sperm injection (ICSI) treatment with GnRH antagonist in the Reproductive Medical Center of Peking University First Hospital from January 2017 to December 2020. A total of 225 patients were divided into OC pretreatment group (119 patients) and non-pretreatment group (106 patients), according to whether they received OC before GnRH antagonist protocol. The baseline information, IVF, and pregnancy outcomes of the two groups were compared. A multivariate logistic regression model was used to analyze the effect of OC pretreatment on cumulative clinical pregnancy of the oocyte retrieval cycle. Results: The age of 225 patients was (31.1±3.3) years old. The ages of patients in the OC pretreatment group and non-pretreatment group were (31.0±3.3) and (31.2±3.3) years old (P>0.05), respectively. The cumulative clinical pregnancy rate of oocyte retrieval cycle was significantly higher in the OC pretreatment group than that in the non-pretreatment group (79.8%, 95 patients; 67.0%, 71 patients; P=0.029). Age <35 years old (OR=3.199, 95%CI: 1.200-8.531, P=0.020), OC pretreatment (OR=3.129, 95%CI: 1.305-7.506, P=0.011), number of oocytes retrieved (OR=1.102, 95%CI: 1.007-1.206, P=0.035) and number of high-quality embryos (OR=1.536, 95%CI: 1.205-1.957, P=0.001) were related factors for the cumulative clinical pregnancy of oocyte retrieval cycle. Conclusions: OC pretreatment before GnRH antagonist protocol can significantly increase the cumulative clinical pregnancy rate of oocyte retrieval cycle in women with PCOS. Age <35 years old, OC pretreatment, the number of oocytes retrieved, and the number of high-quality embryos were related factors for the cumulative clinical pregnancy of oocyte retrieval cycle.

Abstract
BACKGROUND Semen cryopreservation is a critical tool for breed improvement and preservation of biodiversity. However, instability of sperm freezability affects its application. The Mediterranean buffalo is one of the river-type buffaloes with the capacity for high milk production. Until now, there is no specific cryopreservation system for Mediterranean buffalo, which influences the promotion of excellent cultivars. To improve the semen freezing extender used in cryopreservation of Mediterranean buffalo, different protein datasets relating to freezability sperm were analyzed by iTRAQ-based proteomics. This study will be beneficial for further understanding the sperm freezability mechanism and developing new cryopreservation strategy for buffalo semen. RESULTS 2652 quantified proteins were identified, including 248 significantly differentially expressed proteins (DEP). Gene Ontology (GO) analysis indicated that many these were mitochondrial proteins, enriched in the molecular function of phospholipase A2 activity and enzyme binding, and biological processes of regulation of protein kinase A signaling and motile cilium assembly. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis identified 17 significant pathways, including oxidative phosphorylation (OXPHOS). Furthermore, 7 DEPs were verified using parallel reaction monitoring or western blot, which confirmed the accuracy of the iTRAQ data. Peroxiredoxin 6 (PRDX6), which expressed 1.72-fold higher in good freezability ejaculate (GFE) compared to poor freezability ejaculate (PFE) sperms, was selected to explore the function in sperm freezability by adding recombinant PRDX6 protein into the semen freezing extender. The results showed that the motility, mitochondrial function and in vitro fertilization capacity of frozen-thawed sperm were significantly increased, while the oxidation level was significantly decreased when 0.1 mg/L PRDX6 was added compared with blank control. CONCLUSIONS Above results revealed the metabolic pattern of freezability of Mediterranean buffalo sperms was negatively associated with OXPHOS, and PRDX6 had protective effect on cryo-damage of frozen-thawed sperms.

Abstract
Esophageal cancer is a malignant tumor with a high incidence in China. At pesent, advanced esophageal cancer patients are still frequently encountered. The primary treatment for resectable advanced esophageal cancer is surgery-based multimodality therapy, including preoperative neoadjuvant therapy, such as chemotherapy, chemoradiotherapy or chemotherapy plus immunotherapy, followed by radical esophagectomy with thoraco-abdominal two-field or cervico-thoraco-abdominal three-field lymphadenectomy via minimally invasive approach or thoracotomy. In addition, adjuvant chemotherapy, radiotherapy, or chemoradiotherapy, or immunotherapy may also be administered if suggested by postoperative pathological results. Although the treatment outcome of esophageal cancer has improved significantly in China, many clinical issues remain controversial. In this article, we summarize the current hotspots and important issues of esophageal cancer in China, including prevention and early diagnosis, treatment selection for early esophageal cancer, surgical approach selection, lymphadenectomy method, preoperative neoadjuvant therapy, postoperative adjuvant therapy, and nutritional support treatment.

Abstract
Recent advances in multimodality treatment offer excellent opportunities to rethink the paradigm of perioperative management for locally advanced esophageal squamous cell carcinoma. One treatment clearly doesn't fit all in terms of a broad disease spectrum. Individualized treatment of local control of bulky primary tumor burden (advanced T stage) or systemic control of nodal metastatic tumor burden (advanced N stage) is essential. Given that clinically applicable predictive biomarkers are still awaited, therapy selection guided by diverse phenotypes of tumor burden (T vs. N) is promising. Potential challenges regarding the use of immunotherapy may also boost this novel strategy in the future.

Abstract
Objective: To investigate the effects of calorie-restricted diet (CRD), high protein diet (HPD), high protein, and high dietary fiber diet (HPD+HDF) on metabolic parameters and androgen level in overweight/obese patients with polycystic ovary syndrome(PCOS). Methods: Ninety overweight/obese patients with PCOS from Peking University First Hospital from October 2018 to February 2020 were given medical nutrition weight loss therapy for 8 weeks and were randomly divided into CRD group, HPD group, and HPD+HDF group, with 30 patients in each group. Body composition, insulin resistance, and androgen level were detected before and after weight loss, and the efficacy of three weight loss therapies was compared through variance analysis and Kruskal-Wallis H test. Results: Eight patients in CRD group quit because they could not strictly complete the follow-up, therefore at the end of weight loss, 22, 30, and 30 patients in CRD group, HPD group and HPD+HDF group, respectively, were included in the final analysis. The baseline ages of the three groups were (31±2) years, (32±5) years and (31±5) years, respectively (P=0.952). After weight loss, the relevant indicators in HPD group and HPD+HDF group decreased more than those in CRD group. The body weight of CRD group, HPD group and HPD+HDF group decreased by 4.20 (11.92, 1.80), 5.00 (5.10, 3.32) and 6.10 (8.10, 3.07) kg, respectively (P=0.038); BMI of the three groups decreased by 0.80 (1.70, 0.40), 0.90 (1.23, 0.50) and 2.20 (3.30, 1.12) kg/m2, respectively (P=0.002); homeostatic model assessment-insulin resistance(HOMA-IR) index decreased by 0.48(1.93, 0.05), 1.21(2.91, 0.18) and 1.22(1.75, 0.89), respectively (P=0.196); and free androgen index(FAI) decreased by 0.23(0.67, -0.04), 0.41(0.64, 0.30) and 0.44(0.63, 0.24), respectively (P=0.357). Conclusions: The three medical nutrition therapies can effectively reduce the weight of overweight/obese patients with PCOS, and improve insulin resistance and hyperandrogenism. Compared with CRD group, HPD group, and HPD+HDF group have better fat-reducing effect, and can better preserve muscle and basal metabolic rate while losing weight.

Abstract
OBJECTIVES Frailty is a pervasive condition among older people worldwide. Despite the association between higher protein intake and lower frailty risk has been well documented, older individuals encounter barriers to enhancing their protein consumption due to reduced appetite and impaired digestive capacity. This study aims to delve into the potential correlation between dietary protein diversity, protein patterns, and the risk of frailty among older Chinese individuals. DESIGN Prospective cohort study. SETTING Community-based. PARTICIPANTS 2,216 participants aged 65 and above and not frail at the baseline were recruited from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) dataset spanning from 2014 to 2018. MEASUREMENTS Dietary protein diversity was evaluated utilizing a protein diversity score (PDS), calculated based on the results of a food frequency questionnaire. Dietary protein patterns were identified by employing principal component analysis (PCA). Frailty was ascertained using a 40-item frailty index (FI) where FI > 0.21 indicated frailty. Logistic analysis was employed to investigate the association between dietary variables and frailty. RESULTS 541 participants were identified as frail after a 4-year follow-up. After adjusting for confounders, each 1-unit increase in PDS was linked to a 10% decrease in frailty risk. Compared to individuals with PDS ≤ 1, those with PDS scores of 2-3, 4-5, and 6 had lower risks of frailty, with OR (95% CI) of 0.78 (0.58-1.06), 0.58 (0.38-0.87), 0.42 (0.20-0.81), respectively (P trend = 0.038). Individuals who consistently maintained high PDS demonstrated a lower frailty risk in contrast to those who maintained low PDS (OR = 0.60, 95% CI, 0.41-0.87). Additionally, the "meat-fish" pattern exhibited a protective association with frailty, with OR Q4 versus Q1 (95% CI) of 0.54 (0.40-0.74), P trend < 0.001. CONCLUSION Maintaining a variety of dietary protein sources and following a "meat-fish" protein pattern might decrease the likelihood of frailty among the older Chinese population.

Abstract
OBJECTIVES The objective of this 8-year follow-up study was to investigate the relationship between magnesium intake and frailty, as well as recurrent falls, in individuals diagnosed with Osteoarthritis (OA) or those at a heightened risk for developing the condition. METHODS This study utilized data from the Osteoarthritis Initiative (OAI) database and conducted a prospective cohort study with a 8-year follow-up period. Total magnesium intake from both food sources and supplements was assessed using a food frequency questionnaire (FFQ), while frailty and recurrent falls were evaluated through established criteria and self-report, respectively. To account for potential confounding factors, various covariates were considered, and statistical analyses, including generalized additive mixed models (GAMMs), were employed to examine the associations. RESULTS Among the 4,667 participants with OA, those with lower total magnesium intake were characterized by younger age, a higher proportion of African American individuals, higher body mass index (BMI), and lower dietary fiber intake (P<0.001). Notably, this group exhibited higher odds of experiencing recurrent falls and frailty (P = 0.034 and 0.006, respectively). Controlling for various factors, the GAMMs consistently revealed negative correlations between magnesium intake and the likelihood of frailty and recurrent falls, with each 1 mg/1000 kcal increase in magnesium intake associated with a 0.5% reduced frailty risk (p < 0.001) and a 0.2% decreased risk of recurrent falls (p = 0.001). Subgroup analyses suggested that increased total magnesium intake from both food sources and supplements may exert a more pronounced preventive effect on recurrent falls and frailty in men, older adults, individuals with normal BMI, and those with higher dietary fiber intake. CONCLUSIONS Elevated total magnesium intake from both food sources and supplements was found to be associated with a decreased risk of recurrent falls and frailty in individuals diagnosed with OA or those at risk of developing the condition. These findings imply that increased total magnesium intake might be beneficial in managing the risk of these outcomes, particularly within specific subgroups, including men, older adults, those with a normal BMI, and those with higher dietary fiber intake.

Abstract
The cryotolerance of semen obtained from Mediterranean buffalo bulls usually is more likely to deteriorate during the summer. To obtain the optimal sperm for fertility, the physiological status and reproductive performance of Mediterranean buffalo bulls in the summer and spring were first analysed by assessing blood serum and seminal plasma samples; then, the lipid profiles of seminal plasma were investigated by LC-MS/MS. The T, T3 and SOD levels of serum and seminal plasma in the spring were significantly higher than in the summer (p < .05). The results suggest that T3 level is positively correlated with semen cryotolerance; sphingolipids are potential markers for semen cryotolerance of Mediterranean buffalo. To our knowledge, this is the first report of targeted lipidomics in semen cryotolerance.

Abstract
Semen cryopreservation is used for the propagation of variety among species and domestic breeding. Mitochondria are implicated in sperm freezability, and their proteins are prone to succinylation, but the relationship between sperm freezability and mitochondrial protein succinylation is unclear. In this study, six bulls were classified as having good or poor freezability ejaculates (GFE or PFE, each 3 bulls). The fresh sperm mitochondrial membrane potential (MMP) and pan succinylation level of the two groups were first detected. Then the lysine succinylome and fatty acid content of the two groups were analyzed using label-free LC-MS/MS and GC-MS/MS in multiple reaction monitoring (MRM) modes, respectively. The results indicated that the GFE sperm had significantly higher MMPs than the PFE group (p < 0.05). A total of 1393 succinylation sites corresponding to 426 proteins were assessed and 5 succinylated peptides of the GFE group were markedly upregulated, while 3 were significantly downregulated (FC > 2.0 - < 0.5 and p-value < 0.05) when compared to the PFE group. Forty-six succinylated proteins were identified to have consistent presence/absence expression. The upregulated succinylated proteins in the GFE sperm were enriched in lipid metabolic processes. A total of 31 fatty acids were further subjected to quantitative analysis of which 23 including arachidic (C20:0), linolenic (C18:3n3), and docosahexaenoic acids (C22:6n3) were decreased in GFE sperm when compared with PFE (p < 0.05). These results suggest that lysine succinylation can potentially influence the sperm freezability of Mediterranean buffaloes through mitochondrial lipid metabolism. This novel study provides our understanding of sperm succinylation and the molecular basis for the mechanism of sperm freezability.

Abstract
The reconfigurable higher-order topological states are realized in valley photonic crystals with enhanced optical Kerr nonlinearity. The inversion symmetry of the designed valley photonic crystal is broken due to the difference in optical responses between adjacent elements rather than their geometry structures. Therefore, by constructing photonic crystals with distinct topological phases, valley-dependent topological states can be realized, and their reconfigurability is demonstrated based on the Kerr effect. The investigated higher-order topological photonic crystals exhibit great robustness against the structural defects and inferior quality of pump introduced around the corner. Our work provides a new, to the best of our knowledge, platform for studying optical field manipulation and optical devices fabrication in the context of nonlinear higher-order topology.

Abstract
Objective: To investigate the effect of spread through air spaces (STAS) on the postoperative prognosis of patients with stage pT1N0M0 lung adenocarcinoma according to different tumor sizes. Methods: The clinicopathological and follow-up data of 511 patients with pT1N0M0 lung adenocarcinoma treated surgically in the Department of Thoracic Surgery, Cancer Hospital, Chinese Academy of Medical Sciences from January 2014 to June 2018 were retrospectively analyzed. There were 285 males and 226 females, aged 60 (53, 66) years. Those patients were divided into two groups according to STAS status, including STAS (-) group (342 cases) and STAS (+) group (169 cases). And the stratified analysis was performed according to the American Cancer Consortium (AJCC) 8th edition postoperative pathological tumor size T-stage (pT) of lung cancer, which was divided into pT1a (pT≤1 cm, 93 cases), pT1b (1 cm<pT≤2 cm, 280 cases), pT1c group (2 cm<pT≤3 cm, 138 cases) and pT1b/c (1 cm<pT≤3 cm, 418 cases). Univariate and multivariate Cox regression analyses and inverse probability weighted (IPTW) adjusted Kaplan-Meier (K-M) curves were used to analyze the effect of STAS on recurrence-free survival (RFS) in patients included in this study. Results: The recurrence rate was significantly higher in the STAS (+) group compared to the STAS (-) group (22.5% vs 3.2%, P<0.001). Multifactorial Cox regression analysis based on pT stratification showed that the risks of recurrence were 4.56-fold (95%CI:1.56-13.33; P=0.006) and 3.16-fold (95%CI:1.07-9.33; P=0.038) higher in pT1b and pT1c staged patients with STAS (+) than in STAS (-) patients, respectively. There was no significant difference in RFS between the STAS (-) group of pT1b/c, pT1b and pT1c and all pT1a patients [(84.97±0.72) vs (84.05±1.11) months, (85.60±0.74) vs (84.05±1.11) months, (81.49±1.63) vs (84.05±1.11) months; all P>0.05]. Before and after IPTW adjustment, statistically significant differences were found in RFS between STAS (+) group and STAS (-) group [(72.50±2.23) vs (85.12±0.72) months, (77.74±1.12) vs (84.59±0.64) months, all P<0.001]. In addition, the risks of both local and distant recurrence were higher in STAS (+) group compared to STAS (-) group (6.7% vs 1.2% and 8.2% vs 3.6%, respectively; both P<0.05). Conclusion: For lung adenocarcinoma patients with pT1bN0M0 and pT1cN0M0, those patients with STAS (+) had a higher incidence of both local and distant recurrence and with poor RFS.

Abstract
Objective: To investigate the effect of continuous intravenous infusion of subanesthetic dose of esketamine intraoperatively on postoperative opioid consumption in patients undergoing thoracoscopic surgery. Methods: A total of 71 patients with elective thoracoscopic lung surgery in the First Affiliated Hospital of Zhengzhou University from December 2020 to December 2021 were selected. Patients who were classified as grade Ⅰ or Ⅱ by the American Society of Anesthesiologists (ASA) and aged 18-70 years were included, including 32 males and 39 females, with a body mass index (BMI) of 18.5-30.0 kg/m2. The patients were randomly divided into three groups: (1) Control group (group C, n=24): continuous intravenous infusion of normal saline at the same rate during surgery; (2) Subanesthetic dose of esketamine 0.125 mg·kg-1·h-1 group (group ES1, n=23): continuous intravenous infusion of esketamine at a rate of 0.125 mg·kg-1·h-1 during surgery; (3) Subanesthetic dose of esketamine 0.250 mg·kg-1·h-1 group (group ES2, n=24): continuous intravenous infusion of esketamine at a rate of 0.250 mg·kg-1·h-1 during surgery. The main outcome measures were the total consumptions of hydromorphone of 3 groups within 24 and 48 hours after surgery. The secondary outcome measures were the extubation time, length of postanesthesia care unit (PACU) stay, the time of first feeding, and the incidences of adverse effects within 24 h after surgery in 3 groups. Results: The 24 h postoperative consumption of hydromorphone in group C, ES1 and ES2 was (5.4±1.0) mg, (4.5±1.5) mg and (4.0±0.8) mg, respectively. Likewise, the 48 h postoperative consumption of hydromorphone was (9.7±2.2) mg, (9.0±3.0) mg and (7.7±1.8) mg, respectively. Compared with group C, the 24 h postoperative hydromorphone consumptions were significantly reduced in group ES1 and ES2 (both P<0.05). The extubation time, length of PACU stay and the time of first feeding after surgery in group C were (23±10) min,(70±12) min,(17±3) h,in group ES1 were (22±4) min,(69±11) min,(14±5) h,in group ES2 were (16±8) min,(58±12) min,(14±3) h, respectively. Compared with group C and group ES1, both of the extubation time and length of PACU stay were shortened in group ES2 (both P<0.05). Compared with group C, the first postoperative feeding time of group ES1 and ES2 was shortened (both P<0.05). There were no differences in the incidences of adverse effects at postoperative 24 h among 3 groups (all P>0.05). Conclusion: Continuously intravenous infusion of subanesthetic esketamine at a rate of 0.250 mg·kg-1·h-1 can significantly reduce the postoperative opioid consumption and improve the patient's outcomes.

Abstract
This study was intended to define T lymphocyte subsets in different clinical groups of COVID-19-infected patients to explore the interaction between T cell-mediated immune response and the severity of COVID-19 course. Lymphopenia in patients with severe COVID-19 was found. In patients with severe COVID-19 course, the absolute counts of CD3+, CD4+, and CD8+ T lymphocytes at admission were lower than on day 14 after discharge. Further analysis showed that the older were the patients with COVID-19, the more likely they developed severe infection. The results confirmed the significance of T lymphocytes in the clearance of the COVID-19.

Abstract
High-quality semen with high viability is critical to improving the in-vitro fertilization efficiency. This study aimed to understand the effect of ambient temperature and humidity on semen quality and seminal plasma biochemical parameters of Mediterranean buffalo in March and July. The metabolites of seminal plasma in two seasons were detected using the UPLC-MS/MS method. The results showed that temperature and humidity index (THI) in March were 66.86 ± 2.98, and 82.94 ± 3.52 in July. Compared with in March, breath frequency, rectal temperature, and heat shock protein 70 expressions of seminal plasma were significantly increased in July (p < 0.05), motility of sperm was dramatically reduced, and sperm deformity rate was significantly increased (p < 0.05). Fructose, acid phosphatase and α-glucosidase in seminal plasma were significantly increased (p < 0.05) in July, while testosterone level was significantly reduced (p < 0.05). Six different metabolites were found in the two groups, which involved in three metabolic pathways, the tricarboxylic acid cycle, glycerophospholipid, glyoxylic acid and dicarboxylic acid. The above results indicate that the increased ambient temperature has obvious side effects on the semen quality of Mediterranean buffalo, and the compromised quality is associated with the change of metabolites related to male hormone secretion, energy metabolism and fatty acid oxidation.

Abstract
Objective: To investigate the clinical features and the value of different diagnostic indices for etiology in reproductive age women with hyperandrogenism. Methods: The medical records of 96 reproductive age women with hyperandrogenism in the multi-disciplinary team of Peking University First Hospital from January 2020 to April 2021 were collected. The patients were divided into four groups based on final diagnosis: congenital adrenal hyperplasia (CAH) (n=8), polycystic ovary syndrome (PCOS) (n=67), idiopathic hyperandrogenism (n=13) and other specific diseases (n=8), respectively. The indices related to androgens in different groups were compared, and then their efficiency for diagnosis of CAH and PCOS were analyzed with receiver operator characteristic curve (ROC curve). Results: A total of 96 patients with hyperandrogenism were recruited, with the age of 19-45 (29±6) years old. Overall, 4.2% (4/96) of the patients were with single clinical hyperandrogenism, 56.3% (54/96) were with single laboratory hyperandrogenaemia and 39.6% (38/96) were with both. The breakdown into laboratory hyperandrogenaemia subtypes was as follows: only T elevation 22.8% (21/92), only A2 elevation 7.6% (7/92), none DHEAS elevation, only FAI elevation 5.4% (5/92) and elevation of more than one of the androgen indices mentioned above accounted for 64.1% (59/92). In the reasons of consultation, simple irregular menstruation (36.0%, 32/89) or accompanied by clinical hyperandrogenism with or without infertility (36.0%, 32/89) were the most common. As for primary visiting departments, Obstetrics and Gynecology accounted for 53.2% (51/96), and then Endocrinology as 39.5% (38/96). The 17-OHP level of CAH, PCOS and idiopathic hyperandrogenism group was 20.0 (8.2, 33.1), 1.1 (0.8, 1.4), 0.9 (0.8, 1.3) ng/ml, respectively. The androstenedione level in these groups was 6.3 (4.6, 8.7), 3.8 (2.9, 4.8) and 3.2 (2.7, 3.7) ng/ml, respectively. The 17-OHP and androstenedione levels of CAH group were significantly higher than that in PCOS or idiopathic hyperandrogenism group (all P<0.05). The ratio of LH and FSH in these three groups was 0.8(0.5, 1.0), 1.3(0.6, 1.9) and 0.6(0.3, 0.7), respectively. The ratio of LH and FSH was significantly higher in PCOS than that in idiopathic hyperandrogenism group (P=0.024), but yet there was no significant difference compared with CAH group (P>0.05). The AUC of ROC curve of 17-OHP for CAH diagnosis was 0.94, followed by androstenedione 0.83, whereas LH/FSH for PCOS diagnosis was only 0.63. Conclusions: Among the reasons of consultation in reproductive age women who visited our multi-disciplinary team for female hyperandrogenism, simple irregular menstruation or accompanied by clinical hyperandrogenism with or without infertility are the most common. PCOS accounts for the majority of different androgen excess disorders. 17-OHP is the most valuable parameter for the diagnosis of CAH and secondly androstenedione.

Abstract
Objective: To investigate the diagnosis, treatment and prognosis of ureteral endometriosis with hydronephrosis. Methods: A retrospective study was performed of 92 cases diagnosed as ureteral endometriosis with surgery confirmed in Peking University First Hospital from January 2000 to January 2021. Results: The incidence of ureteral endometriosis was 0.9% (92/10 222), with an average age of (40.0±6.0) years. Among 92 cases, urological symptoms and pelvic pain including dysmenorrheal, periodic abdominal pain were the main forms of clinical characteristics, while 11 patients (12%, 11/92) were asymptomatic. All patients with ureteral endometriosis had hydronephrosis and hydroureter before surgery, hydronephrosis were left sided in 48 (52%, 48/92) patients, right sided in 39 (42%, 39/92) patients, both sided in 5 (5%,5/92) patients. The distal and middle sections of ureteral obstructions existed in 73 (79%, 73/92) patients and 19 (21%, 19/92) patients, respectively. Out of the 92 ureteral lesions 71 (77%, 71/92) patients were extrinsic lesions, 21 (23%, 21/92) patients presented intrinsic lesions. Of the 38 cases who took preoperative radionuclide renal dynamic imaging examination, there were 6 (16%, 6/38) cases of mildly damaged, 7 (18%, 7/38) cases of moderately dameged, 14 (37%, 14/38) cases of severely damaged, and 11 (29%, 11/38) cases of normal renal function. Laparotomy was decided in 25 (27%, 25/92) patients, and laparoscopic surgery in 67 (73%, 67/92) patients. In cases of ureteral surgery, ureterolysis, partial ureteral resection and ureterocystoneostomy, partial ureteral resection and end-to-end ureteral anastomosis and nephroureterectomy were undertaken in 52 (57%, 52/92), 20 (22%, 20/92), 12 (13%, 12/92) and 8 (9%, 8/92) patients separately. The median follow up was 108 months (range: 6 to 240 months). During the follow-up period, 68 (87%, 68/78) patients took urinary ultrasound after surgery, and 60 (88%, 60/68) cases of hydronephrosis disappeared, and 8 (12%, 8/68) cases were better than before. Conclusion: Most of the patients with ureteral endometriosis are impaired with renal function, and early surgical treatment could effectively relieve urinary obstruction and promote the recovery of renal function.

Abstract
Objective: To investigate the effect and mechanism of tumor necrosis factor α (TNF-α) and its inhibitor etanercept (ETA) on the invasion ability of extravillous trophoblast in patients with unexplained recurrent spontaneous abortion (URSA). Methods: (1) Patients were collected from March to June in 2019. They were divided into the URSA group (n=15) and the normal control group (n=15), according to whether diagnosed with URSA or not. The mRNA expression levels of TNF-α in villi tissue of patients in the two groups were detected by quantitative real-time PCR (qRT-PCR). (2) The mRNA and protein expression levels of matrix metalloproteinase-2 (MMP-2), Slug and CXC chemokine rceptor 4 (CXCR4) in HTR-8/SVneo cells were detected by qRT-PCR or western blot after being stimulated by exogenous TNF-α (0.2, 2, 20 ng/ml) alone or TNF-α along with ETA, or phosphate buffered saline (PBS) as control. (3) The invasion ability of HTR-8/SVneo cells was investigated by transwell test after stimulating by TNF-α alone or TNF-α along with ETA. (4) The mRNA and protein expression levels of MMP-2, Slug and CXCR4 in HTR-8/SVneo cells, which were stimulated by TNF-α (2 ng/ml) alone after nuclear factor-κB (NF-κB) inhibitor, BAY 11-7028, preconditioning, were detected by qRT-PCR or western blot. Results: (1) The mRNA expression level of TNF-α in villi tissue of URSA group (4.10±0.49) was 4.1 times as much as the normal control group (t=10.51, P<0.05). (2) The mRNA and protein expression levels of MMP-2, Slug and CXCR4 in HTR-8/SVneo cells of TNF-α group were significantly lower than those in PBS control group (P<0.05) and those in TNF-α along with ETA group (P<0.05). (3) The invasion ability of HTR-8/SVneo cells in TNF-α group was significantly decreased than PBS group and TNF-α along with ETA group (78±14 vs 373±26 vs 227±44, P<0.05). (4) The mRNA and protein expression levels of MMP-2, Slug and CXCR4 in HTR-8/SVneo cells with BAY 11-7028 preconditioning (mRNA: 1.03±0.10, 1.03±0.06, 1.09±0.08; protein: 1.09±0.03, 1.49±0.03, 1.12±0.03) were significantly higher than without preconditioning after being stimulated by TNF-α (all P<0.05). Conclusions: The expression of TNF-α in the villi of URSA patients is much higher than normal early pregnant women. TNF-α could decrease the capacity of invasion by suppressing the expression of MMP-2, Slug and CXCR4 through NF-κB signaling pathway in extravillous trophoblast cells. While ETA could improve the invasiveness capability of extravillous trophoblast cells through inhibiting the negative effect of TNF-α.

Abstract
Objective: To evaluate the clinical effect of oral contraceptive (OC) pretreatment on the outcome of gonadotropin releasing hormone antagonist (GnRH-a) protocol in patients with non-polycystic ovary syndrome. Methods: From January 2017 to May 2019, a total of 436 patients undergoing in vitro fertilization and embryo transfer/Intracytoplasmic sperm injection (IVF-ET/ICSI) treatment in Peking University First Hospital reproductive center clinic were included in this retrospective cohort study. A total of 144 patients (147 cycles) used OC pretreatment prior to GnRH-a protocol and 292 patients (306 cycles) used GnRH-a protocol without OC pretreatment. The drug usage as well as pregnant outcomes between groups were examined. The primary outcome was the cumulative clinical pregnancy rate of oocyte retrieval cycle and the secondary outcome included the number of oocytes, MⅡ oocytes, embryos and clinical pregnancy rate of fresh embryo transfer cycle. Results: The median ages (and Q1, Q3) of OC pretreatment group and non-OC group were 33 (30,36) and 34 (30,38) years old, respectively. The number of MⅡ oocytes was higher in OC pretreatment group (7/9) than in non-OC group (6/8) (P=0.002). The significant difference were not found in the cumulative clinical pregnancy rate of each oocyte retrieval cycle (61.7% vs 54.6%), the clinical pregnancy rate of fresh embryo transfer cycle (34.4% vs 35.6%), and the number of oocytes (9 vs 8) and embryos (6 vs 6) between groups. Conclusion: Our findings suggest that compared to non-OC pretreatment group, pretreatment with OC is associated with more MⅡ oocytes, and with an increasing trend of the cumulative clinical pregnancy rate in non-polycystic ovary syndrome patients undergoing fresh IVF-ET/ICSI.

Abstract
The incidence and mortality of lung cancer ranked the first in China. China had 787, 000 new cases of lung cancer in 2015, and a majority of these patients with advanced lung cancer. With the development and popularization of high-resolution computed tomography, more and more early-stage lung adenocarcinomas are found in screening. The imaging finding of early-stage lung adenocarcinomas often manifests as part solid nodule (PSN) containing ground glass opacity (GGO). Although the imaging manifestation of the nodules can't accurately predict the pathologic type of nodules, the parts of solid nodule and GGO still have some pathologic indications, and the prognostic evaluation effect of the maximum diameter of PSN is superior to that of the whole nodule. With the development of the molecular radiography and molecular pathology, the relationship of imaging manifestation of the PSN and metastasis were focused on. Some PSNs with special nature are more active and rapidly progressed than the pure GGOs. While compared to the pure solid nodules, the aggressiveness of PSNs are insufficient, with lower metastatic rates of lymph node and better prognoses. Currently, international acknowledge recommends to take active intervention measure for PSNs which are highly suspected to be malignant. We focus on the diagnosis and treatment of PSNs, systemically depict their staging, follow-up, surgical treatment, gene detection and immunotherapy.

Abstract
OBJECTIVE Increasing evidence indicated that N6-methyl-adenosine (M6A) played a key role in a variety of pathophysiological processes. Methylases could promote the processing of mature mi-RNA in a M6A-dependent manner, thereby participating in the pathological cells' occurrence and development. However, the regulatory mechanism of M6A in atherosclerosis (AS) was still unclear. PATIENTS AND METHODS Quantificational Real-time polymerase chain reaction (qRT-PCR) was used to detect the relative expression levels of M6A, methyltransferase, demethylase transferase, miR-19a and other mi-RNA in atherosclerotic vascular endothelial cells (ASVEC). Cell Counting Kit (CCK8) was used to detect cell proliferation, the expression of PCNA was measured by Western Blot (WB) and qRT-PCR. Transwell assays were used to detect the invasion ability of ASVEC. Co-immunoprecipitation (Co-IP) was used to detect the binding of METTL14 to DGCR8. RNA Immunoprecipitation (RIP) was used to detect the binding of METTL14 to miR-19a. RESULTS M6A modification levels and METTL14 methylation transferase were significantly overexpressed in ASVEC. Silencing METTL14 inhibited the proliferation and invasion of ASVEC. Low expression of METTL14 suppressed the binding of methylated RNA and RNA splicing related protein DGCR8. Moreover, silencing METTL14 significantly inhibited the expression of miR-19a while promoted the expression of primary pre-miR-19a. However, high expression of METTL14 obviously increased the expression of DGCR8 and methylated m6A. Furthermore, silencing miR-19a inhibited the proliferation and invasion of ASVEC. CONCLUSIONS METTL14 increased the M6A modification of pri-miR-19a and promoted the processing of mature miR-19a, thus promoting the proliferation and invasion of ASVEC. These results suggested that METTL14/ M6A/ miR-19a signaling pathway may be a new target for atherosclerosis treatment.

Abstract
Objective: To explore the feasibility, safety and effectiveness of anatomical partial lobectomy. Methods: The clinical data of 3 336 patients with lung nodules underwent anatomical partial lobectomy in our center from November 2013 to November 2019 were retrospectively analyzed. We set the safety margin distance according to the imaging feature of the lesion. The surgeons then anatomically detached the major vessels and bronchus in this region, resected the targeted lung tissue along the plane, and completed the resection of anatomical pulmonary lobe and clean and sampling of systemic lymph nodules. Results: A total of 668 cases were multiple nodules and 2 668 cases were solitary pulmonary nodules. According to the postoperative pathological results, 283 cases were benign, 1 197 cases were preinvasive lesions (including 38 cases of atypical adenomatous hyperplasia, 445 cases of adenocarcinoma in situ and 714 cases of minimally invasive adenocarcinoma), 1 713 cases were invasive adenocarcinoma, 73 cases were non-adenocarcinoma and 70 cases were metastatic carcinoma. Among 1 786 invasive primary lung cancers, 11 cases received preoperative neoadjuvant chemotherapy, and their postoperative pathologic diagnoses were stage ypIA. Other 1 775 cases who did not receive postoperative neoadjuvant treatment included 1 587 cases in stage ⅠA, 112 cases in stage ⅠB, 3 cases in stage ⅡA, 18 cases in stage ⅡB, 37 cases in stage ⅢA, 9 cases in stage ⅢB, 9 cases in stage Ⅳ. The average operation time was (127.3±55.3) minutes, and the mean postoperative hospital stay was (4.8±2.4) days. The incidence rate of complications (grade>2) was 1.1%(38/3 336), and no death occurred during 30 days after operation. Conclusion: Anatomic partial lobectomy has good clinical applicability, safety and effectiveness, which is worthy of clinical application and recommendation.

Abstract
Objective: To investigate the rule of mediastinal lymph node metastasis of papillary thyroid carcinoma and the application of therapeutic mediastinal lymph node dissection through the sternotomy approach in the treatment of mediastinal lymph node metastasis of papillary thyroid carcinoma. Methods: All cases of papillary thyroid carcinoma with mediastinal lymph node metastasis treated through sternotomy cooperated by thoracic surgeons and head and neck surgeons from January 2006 to January 2017 in Cancer Hospital of Chinese Academy of Medical Sciences were included in this study. The distribution, metastasis rate, metastasis degree, surgical method, surgical complications and postoperative survival of patients with mediastinal lymph node metastasis were retrospectively analyzed. Results: A total of 31 patients (16 males and 15 females) with papillary thyroid cancer with mediastinal lymph node metastasis, with a median age of 46 (19-65) years, were enrolled in the group. Partial upper sternotomy was used in 28 cases, and total sternotomy was used in 3 cases. The mediastinal lymph nodes of papillary thyroid carcinoma metastasized farthest to the station 6, and the lymph node metastasis rate of each group from high to low was: 2R (61%), 1R (39%), 3A (39%), 1L (16%), 2L (10%), 4R (10%), 5 (3%) and 6 (3%). No metastasis was observed in station 3P, 4L and 7. In addition, the degree of lymph node metastasis at station 2R was the highest, reaching 35% (77/219). Extra-nodal invasion of mediastinal metastatic lymph nodes in thyroid papillary carcinoma is common (23%), easily fuses into masses (23%) and invades peripheral vascular nerves (26%). Up to 29% of blood transfusions are required during or after surgery due to oozing or bleeding (9/31). The 1-, 3-, 5-and 10-year survival rates of patients undergoing surgical treatment were 94%, 94%, 87% and 81%, respectively. Conclusion: Papillary thyroid carcinoma can metastasize to almost all mediastinal lymph nodes except station 3P, 4L and 7. Radical mediastinal lymph node dissection through sternotomy is an effective method for the treatment of mediastinal lymph node metastasis of thyroid papillary carcinoma.

Abstract
Objective: To examine the results of surgical treatment for endograft infection after thoracic endovascular aortic repair (TEAVR). Methods: Clinical data of 7 patients underwent surgical treatment for endograft infection after TEAVR at Department of Cardiothoracic Surgery, Changhai Hospital, the Navy Medical University between January 2016 and December 2018 were analyzed retrospectively. There were 6 males and 1 female, aging (51.5±16.7) years (range: 25 to 68 years). The origin of the aortic disease was descending aortic aneurysm in 5 cases, and Stanford B aortic dissection in 2 cases. Abdominal aorta below the level of the diaphragm was not involved in all patients. Two patients received "chimney technology" for left subclavian artery procedures. Time to infection was 5(3) months (M(Q(R))) (range: 1 to 24 months). Aortic endograft infection was diagnosed with a combination of microbiology (positive blood cultures, except one with mycotic), radiological evidence and clinical evidence of sepsis. Two patients suffered from aorto-esophageal fistula received emergency surgery, others were treated with elective surgery. Extra-anatomic prosthetic graft bypass was used for reconstruction of aorta, infected endogarft and aorta was removed, sac drainage was performed. Aorto-esophageal fistula was procedured according to the degree of lesions. All patients received antibiotics with specialist advice for 6 to 8 weeks. Results: One patient died due to septic shock. In the follow-time (range: 6 to 24 months), 1 patient suffered from thoracic infection in 3 months after surgery, an other patient got iliac abscess after a month. Conclusions: Endograft infection after TEAVR is high risk but may be curative. Appropriate selection of patients for infected endograft explantation could get a satisfied results.

Abstract
AIMS The aims of this study were to investigate the biocontrol effects of Penicillium griseofulvum strain CF3 and its mechanisms against soil-borne root pathogens (Fusarium oxysporum and Sclerotium rolfsii) of the medical plant Aconitum carmichaelii Debx. METHODS AND RESULTS The effects of P. griseofulvum strain CF3 were evaluated with regard to the hyphal growth of S. rolfsii and F. oxysporum, the sclerotial formation and germination of S. rolfsii and its expression of sclerotia-formation-related genes. A field experiment was conducted to explore how strain CF3 controls the severity of soil-borne diseases, promotes the growth of A. carmichaelii plants and mediates shifts in the culturable rhizosphere microbial populations. The results showed that treatment with a cell-free culture filtrate of strain CF3 considerably inhibited the hyphal growth of both S. rolfsii and F. oxysporum, in addition to limiting the sclerotial formation and germination of S. rolfsii. Three genes related to sclerotial formation (ArsclR, ArnsdD1 and ArnsdD2) were predicted in S. rolfsii and their expression was found suppressed by the CF3 treatment. Field application of the CF3 biocontrol agent in a powder form (1·9 × 1010 conidia per gram of substrate) reduced soil-borne disease severity by 15·0%. The shoot and root growth of A. carmichaelii plants was promoted by 61·6 and 83·1% respectively, as the biocontrol strain massively colonized the rhizosphere soil. The CF3 treatment also markedly reduced the density of some known species harmful to plants while increasing the density of some beneficial species in the rhizosphere soil. SIGNIFICANCE AND IMPACT OF THE STUDY Genes related to sclerotia formation of S. rolfsii are predicted for the first time and their expression patterns in the presence of P. griseofulvum strain CF3 are evaluated.

Abstract
Objective: To compare the expression of leukemia inhibitory factor (LIF), interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) in tissue and fluid samples from patients with endometriosis, and investigate whether LIF and IL-6 regulate VEGF in human endometriotic stromal cells (ESC). Methods: The levels of VEGF, LIF, IL-6 in serum, peritoneal fluid of patients with and without endometriosis were measured by ELISA. The mRNA of these three factors in the ectopic and eutopic endometrial tissue and stromal cells were measured by real-time PCR. ESC derived from ovarian endometriomas were cultured using the method of primary cell culture with LIF and IL-6, and the level of VEGF mRNA and protein were measured by the method of real-time PCR and ELISA respectively. Results: VEGF and IL-6 concentration were 1.2 and 1.3 times higher in the serum of patients with endometriosis than in the control group [(94±19) versus (78±17) ng/L; (45±14) versus (35±9) ng/L; all P<0.05]. VEGF and IL-6 concentration were 1.2 and 1.4 times higher in the peritoneal fluid of patients with endometriosis than in the control group [(110±25) versus (91±21) ng/L; (69±20) versus (49±15) ng/L; all P<0.05]. VEGF and IL-6 concentrations in peritoneal fluid of patients with endometriosis were 1.2 and 1.5 times higher than in serum (all P<0.01). VEGF, LIF and IL-6 mRNA expression were 2.2, 8.6, 44.7 times higher in ESC compared with the matching eutopic endometrial stromal cells (all P<0.01). LIF and IL-6 mRNA were 2.0 and 64.8 times higher in ectopic endometrial tissue than the matching eutopic endometrial tissue (all P<0.05).ESC cultured with LIF, IL-6 and LIF+IL-6 induce VEGF protein secretion [(106±18), (124±30), (140±27) ng/L] by 1.3, 1.5 and 1.7 times (all P<0.05). Conclusion: Overexpression of LIF and IL-6 may synergistically contribute to upregulation of VEGF in ESC and promote development of endometriosis.

Abstract
Objective: To elucidate whether metformin could regulate the mRNA expression level of estrogen synthetase and ER in human uterine leiomyoma tissues. Methods: (1) Seventeen pairs of uterine leiomyoma tissues and adjacent myometrium (>2 cm) were collected from patients underwent hysterectomy in Peking University First Hospital between December 2016 and January 2017. Real-time PCR was used to measure the mRNA expression level of estrogen synthetase [including cytochrome P450 cholesterol side chain cleavage enzyme (P450scc), cytochrome P450 17α-hydroxylase (P450c17), 3-beta-hydroxysteroid dehydrogenase type 2 (3β-HSD-2), 17-beta-hydroxysteroid dehydrogenase type 1 (17β-HSD-1) and aromatase cytochrome P450 (P450arom)] and ER (including ERα and ERβ) in the uterine leiomyoma tissues and adjacent myometrium. (2) Uterine leiomyoma cells derived from uterine leiomyoma tissues were identified by immunocytochemistry method and cultured to the third generation. The treatment groups were cultured with different concentrations of metformin (10, 50 and 100 μmol/L) for 48 hours, and the control group was cultured with deionized water for 48 hours. The mRNA expression level of estrogen synthetase and estrogen receptor subtypes were measured by real-time PCR. Results: (1) P450scc, P450c17, 3β-HSD-2, 17β-HSD-1, P450arom mRNA median expression levels were 112, 4, 13, 42 and 194 in the uterine leiomyoma tissues, and were respectively 114, 5, 11, 32 and 6 in the myometrium. Compared to those of the myometrium, 3β-HSD-2 and P450arom mRNA expression levels in the uterine leiomyoma tissue were significantly higher (P<0.05), while there were no significant change of mRNA expression levels among P450scc, P450c17 and 17β-HSD-1 (P>0.05). ERα and ERβ mRNA median expression levels were 208 and 116 in the uterine leiomyoma tissues, and were 24 and 95 in the myometrium. Compared to that of the myometrium, ERα mRNA level in the uterine leiomyoma tissue was significantly higher (P=0.001), while there were no significant change of ERβ mRNA level (P=0.193). (2) After cultured with different concentrations of metformin (10, 50 and 100 μmol/L), the P450arom mRNA levels in the uterine leiomyoma tissues were 9±4, 8±5 and 8±3 respectively in the treatment groups and was 16±5 in the control group. Compared to that of the control group, P450arom mRNA expression levels in the treatment groups were significantly declined (P<0.05). There were no significant different change of mRNA expression levels among 3β-HSD-2, ERα and ERβ between the treatment groups and the control group (P>0.05). Conclusions: Metformin could down-regulate the mRNA expression level of aromatase in the uterine leiomyoma cells. These results indicate that metformin may inhibit the local estrogen synthesis and therefore suppress the development of uterine leiomyoma.

Abstract
Objective: The role of planned neoadjuvant radiotherapy or chemoradiotherapy in the non-radical resection of esophageal squamous cell carcinoma was unclear. The study aimed to evaluate their therapeutic effect and analyze the prognostic factors. Methods: We retrospectively analyzed the clinical data of locally advanced esophageal squamous cell carcinoma who received neoadjuvant radio therapy (33 patients) and concurrent chemoradiotherapy (119 patients) from January 2004 to December 2016 in our single-institution database.The survival rates were calculated by Kaplan-Meier method. The prognostic factors were analyzed by using Log rank test and Cox proportional hazards model. Results: The median follow-up was 29.8 months. One hundred and one patients survived more than 3 years. The rates of overall survival (OS) and disease-free survival (DFS) at 3 years were 63.9% and 55.6%, respectively.The rates of complete, partial and minimal pathological response of the primary tumor were 50.3%, 38.4%, 11.3%, the corresponding 3-year OS were 75.5%, 57.4%, 27.3% (P<0.001) and 3-year DFS were 72.0%, 44.7%, 17.6% (P<0.001), respectively.The postoperative lymph node metastasis rate was 27.0%. The 3-year OS and DFS of the lymph node positive group was 45.6% and 32.8%, significantly lower than 70.8% and 63.7% of the negative group (both P<0.001). The 3-year OS and DFS of pathologic stage Ⅰ, Ⅱ, ⅢA, ⅢB and Ⅵ A were 76.2%, 57.4%, 64.7%, 35.0%, 33.3% (P<0.001) and 70.1%, 49.3%, 41.2%, 22.1%, 33.3% (P<0.001), respectively.The operation-related mortality was 3.3%. Multivariate analysis showed that chest pain, postoperative respiratory failure, pathological differentiation, more than 15 lymph node dissection and ypTNM stage were the independent prognostic factors of OS (P<0.05 for all). Conclusions: The planned neoadjuvant radiotherapy or chemoradiotherapy for the non-radical resection of advanced esophageal squamous cell carcinoma could result in favorable survival. The chest pain, postoperative respiratory failure, pathological differentiation, the number of lymph node resection and ypTNM stage are the independent prognostic factors of the prognosis of these patients.

Abstract
Objective: Adenosquamous carcinoma of lung is an uncommon subtype with more aggressive behavior and poor prognosis than adenocarcinoma and squamous cell carcinoma. This study was aimed to investigate the clinicopathological characteristics and prognostic factors of lung adenosquamous carcinoma. Methods: The pathological features and follow-up data of 133 patients were collected and the prognostic factors of these patients were retrospectively analyzed. Results: Among the 133 patients, 81 cases (60.9%) smoked. Among the 62 patients whose percentage of histological components were identified, 45 cases had >50% adenocarcinoma components, and 17 cases had >50% squamous cell carcinoma components. 55 patients had lymph node metastasis at the first visit. All patients accepted at least one test of tumor driven gene mutation, and the results showed that the mutation rate of EGFR was 50.8% (67/132), the mutation rate of K-ras was 8.6% (11/128), the ALK-positive rate was 4.2% (2/48). The gender, smoking status, and the proportion of pathological components were the main influence factors of EGFR mutation status. The median overall survival was 28 months, the rates of 1-year, 3-year, and 5-year survival were 72.9%, 23.3%, and 9.0%, respectively. EGFR tyrosine kinase inhibitors (TKIs) treatment was an independent risk factor for prognose of these patients (P=0.024). Conclusions: Lung adenosquamous carcinoma is a rare subtype with high malignancy and poor prognosis. Early diagnosis and driven-mutation-based individualized therapy may improve the survival of patients with lung adenosquamous carcinoma.
