Abstract
Recent studies have attracted intense attention on the quasi-2D kagome superconductors AV_{3}Sb_{5} (A=K, Rb, and Cs) where the unexpected chiral flux phase (CFP) associates with the spontaneous time-reversal symmetry breaking in charge density wave states. Here, commencing from the 2-by-2 charge density wave phases, we bridge the gap between topological superconductivity and time-reversal asymmetric CFP in kagome systems. Several chiral topological superconductor (TSC) states featuring distinct Chern numbers emerge for an s-wave or a d-wave superconducting pairing symmetry. Importantly, these CFP-based TSC phases possess unique gapless edge modes with mixed chiralities (i.e., both positive and negative chiralities), but with the net chiralities consistent with the Bogoliubov-de Gennes Chern numbers. We further study the transport properties of a two-terminal junction, using Chern insulator or normal metal leads via atomic Green's function method with Landauer-Büttiker formalism. In both cases, the normal electron tunneling and the crossed Andreev reflection oscillate as the chemical potential changes, but together contribute to plateau transmissions (1 and 3/2, respectively) that exhibit robustness against disorder. These behaviors can be regarded as the signature of a TSC hosting edge states with mixed chiralities.

Abstract
Various dissipative soliton solutions exist in the parameter space of mode-locked fiber lasers, including both coherent and incoherent pulses. Novel ultrafast laser designs can lead to distinctive dissipative soliton solutions formed by unique pulse shaping dynamics in the same cavity. However, transitionary states in between steady-state mode-locked regimes remain largely unexplored. Here, we investigate the intermediate transition dynamics in a versatile Tm-doped fiber laser capable of emitting both dissipative solitons with anomalous-dispersion and normal-dispersion pulse-shaping mechanisms by adjusting an intracavity polarization controller. Real-time pulse dynamics during mode-locking transitions are analyzed with a modified dispersive Fourier transform setup, illustrating characteristic pulse shaping mechanisms typically reserved for different dispersion regimes. Combined with a spectral intensity correlation analysis, the coherence evolution between two distinct mode-locked states is fully resolved for the first time.

Abstract
The Southern Ocean is a major sink of atmospheric CO2, but the nature and magnitude of its variability remains uncertain and debated. Estimates based on observations suggest substantial variability that is not reproduced by process-based ocean models, with increasingly divergent estimates over the past decade. We examine potential constraints on the nature and magnitude of climate-driven variability of the Southern Ocean CO2 sink from observation-based air-sea O2 fluxes. On interannual time scales, the variability in the air-sea fluxes of CO2 and O2 estimated from observations is consistent across the two species and positively correlated with the variability simulated by ocean models. Our analysis suggests that variations in ocean ventilation related to the Southern Annular Mode are responsible for this interannual variability. On decadal time scales, the existence of significant variability in the air-sea CO2 flux estimated from observations also tends to be supported by observation-based estimates of O2 flux variability. However, the large decadal variability in air-sea CO2 flux is absent from ocean models. Our analysis suggests that issues in representing the balance between the thermal and non-thermal components of the CO2 sink and/or insufficient variability in mode water formation might contribute to the lack of decadal variability in the current generation of ocean models. This article is part of a discussion meeting issue 'Heat and carbon uptake in the Southern Ocean: the state of the art and future priorities'.

Abstract
Here, we propose that Floquet engineering offers a strategy to realize the nonequilibrium quantum anomalous Hall effect (QAHE) with tunable Chern number. Using first-principles calculations and Floquet theorem, we unveil that QAHE related to valley polarization (VP-QAHE) is formed from the hybridization of Floquet sidebands in the two-dimensional family MSi2Z4 (M = Mo, W, V; Z = N, P, As) by irradiating circularly polarized light (CPL). Through the tuning of frequency, intensity, and handedness of CPL, the Chern number of VP-QAHE is highly tunable and up to C = ±4, which attributes to light-induced trigonal warping and multiple-band inversion at different valleys. The chiral edge states and quantized plateau of Hall conductance are visible inside the global band gap, thereby facilitating the experimental measurement. Our work not only establishes Floquet engineering of nonequilibrium VP-QAHE with tunable Chern number in realistic materials but also provides an avenue to explore emergent topological phases under light irradiation.

Abstract
Giant cell tumors (GCTs) of the bone are locally aggressive primary bone tumors with a benign character. Spinal involvement is rare which accounts for approximately 5% of all primary bone tumors and it is quite rare in the lumbar spine. An 11-year-old boy patient presented with pain of low back and bilateral low extremities. Lumbar CT and MRI revealed a lytic lesion of the L4 vertebra corpus. The patient earned remarkable and timely recovery with 2 surgical interventions and the use of denosumab. Surgical resection for GCTs is still preferable as the initial treatment, denosumab should be utilized after tumor resection whether based on the purpose of prevention or treatment of tumor recurrence.

Abstract
OBJECTIVE To explore the molecular mechanisms of Porphyromonas gingivalis infection-induced umbilical vein endothelial barrier dysfunction in vitro. METHODS Human umbilical vein endothelial cells (HUVECs) were cultured in vitro, and after the formation of the endothelial barrier, the cells were infected with P. gingivals at a multiplicity of infection (MOI). The transepithelial electrical resistance (TEER) of the cell barrier was measured, and FITC-dextran trans-endothelial permeability assay and bacterial translocation assay were performed to assess the endothelial barrier function. The expression levels of cell junction proteins including ZO-1, occludin and VE-cadherin in the cells were examined by qRT-PCR and Western blotting. RESULTS In freshly seeded HUVECs, TEER increased until reaching the maximum on Day 5 (94 Ωcm2), suggesting the formation of the endothelial barrier. P. gingivals infection caused an increase of the permeability of the endothelial barrier as early as 0.5 h after bacterial inoculation, and the barrier function further exacerbated with time, as shown by significantly lowered TEER, increased permeability of FITC-dextran (40 000/70 000), and increased translocation of SYTO9-E. coli cross the barrier. MTT assay suggested that P. gingivals infection did not significantly affect the proliferation of HUVECs (P>0.05), but in P. gingivalsinfected cells, the expressions of ZO-1, occludin and VE-cadherin increased significantly at 24 and 48 h after bacterial inoculation (P < 0.05). CONCLUSION P. gingivals may disrupt the endothelial barrier function by down-regulating the expressions of the cell junction proteins (ZO-1, occludin, VE-cadherin) and increasing the permeability of the endothelial barrier.

Abstract
BACKGROUND Urinary and sexual dysfunctions are among the most common complications in rectal cancer surgery. This study aimed to investigate the protective effect of laparoscopic functional total mesorectum excision (TME) on urinary and sexual functions in male patients. METHODS A total of 248 male patients with mid-low rectal cancer were recruited in this study between February 2017 and July 2020. To overcome selection bias, we performed a 1:1 match using six variables, including age, BMI, ASA score, tumor distance, clinical T stage, and tumor size. The urinary function was assessed by the International Prostate Symptom Score (IPSS), sexual function was assessed by a 5-item version of the International Index of Erectile Function (IIEF-5) and ejaculation grading at postoperative 3 and 12 months. RESULTS 79 patients received functional TME surgery (FTME group), and 169 patients received routine TME surgery (RTME group). After the propensity score, 79 pairs were balanced and analyzed. Patients in the FTME group showed a lower IPSS score and higher IIEF-5 score than patients in the RTME group at postoperative 3 and 12 months. The incidence of ejaculation dysfunction for patients in the FTME group was lower than patients in the RTME group at postoperative 3 and 12 months. CONCLUSION Laparoscopic functional total mesorectal excision was beneficial to faster recovery of urinary and sexual function for patients with rectal cancer, and it could be used as a superior surgical technique for pelvic autonomic nerve preservation in mid-low rectal cancer.

Abstract
Background The currently available prediction models, such as the Cox model, were too simplistic to correctly predict the outcome of gastric adenocarcinoma patients. This study aimed to develop and validate survival prediction models for gastric adenocarcinoma patients using the deep learning survival neural network. Methods A total of 14,177 patients with gastric adenocarcinoma from the Surveillance, Epidemiology, and End Results (SEER) database were included in the study and randomly divided into the training and testing group with a 7:3 ratio. Two algorithms were chosen to build the prediction models, and both algorithms include random survival forest (RSF) and a deep learning based-survival prediction algorithm (DeepSurv). Also, a traditional Cox proportional hazard (CoxPH) model was constructed for comparison. The consistency index (C-index), Brier score, and integrated Brier score (IBS) were used to evaluate the model's predictive performance. The accuracy of predicting survival at 1, 3, 5, and 10 years was also assessed using receiver operating characteristic curves (ROC), calibration curves, and area under the ROC curve (AUC). Results Gastric adenocarcinoma patients were randomized into a training group (n = 9923) and a testing group (n = 4254). DeepSurv showed the best performance among the three models (c-index: 0.772, IBS: 0.1421), which was superior to that of the traditional CoxPH model (c-index: 0.755, IBS: 0.1506) and the RSF with 3-year survival prediction model (c-index: 0.766, IBS: 0.1502). The DeepSurv model produced superior accuracy and calibrated survival estimates predicting 1-, 3- 5- and 10-year survival (AUC: 0.825-0.871). Conclusions A deep learning algorithm was developed to predict more accurate prognostic information for gastric cancer patients. The DeepSurv model has advantages over the CoxPH and RSF models and performs well in discriminative performance and calibration.

Abstract
Objective: To evaluate the safety and feasibility of robotic-assisted thoracoscopic day surgery for pulmonary nodules. Methods: Clinical data of 523 patients with pulmonary nodule underwent robotic-assisted thoracoscopic surgery in the Department of Thoracic Surgery, Xiangya Hospital, Central South University from January 2021 to June 2022 were retrospectively analyzed, which including 223 males and 300 females, aged from 19 to 72 (54.0±11.7) years. Those patients were divided into the day surgery group (DSG) and inpatient surgery group (ISG) according to perioperative management methods. Propensity score matching (PSM) (1∶2) was performed according to the general baseline information, T stage of the tumor, surgery approach, and tumor position, and a total of 178 patients were finally included. Clinical outcomes of DSG were observed. The differences in incidence of postoperative complications, treatment-related costs and resource consumption between DSG and ISG were compared. Subgroup analysis was performed according to surgery method to evaluate the difference between DSG and ISG in lobectomy and sublobectomy. Results: In 81 cases DSG, eight patients were transferred to thoracic surgery ward, and the day surgery discharge rate was 90% (73/81). There was no statistically significant difference in incidence of postoperative complications between DSG and ISG (P=0.612). The length of stay after surgery, period of chest draining, average hospital cost, and drug cost of DSG were statistically significant lower than ISG, ((2.19±0.84) vs (4.74±1.81) days, (1.70±0.65) vs (3.45±1.85) days, (6.64±0.74) vs (8.29±0.97)×104 CNY, (0.35±0.07) vs (0.69±0.18)×104 CNY), respectively(all P<0.05). The drainage volume and VAS score at discharge in DSG and ISG group were(220.47±120.02) ml and(242.21±129.96) ml, 1.68±0.79 and 1.64±0.91, respectively, with no statistically significant difference (P>0.05). In subgroup analysis, there was no statistically significant difference in incidence of postoperative complications, drainage volume after surgery and VAS score at discharge between DSG and ISG both for lobectomy and sublobectomy patients. And the results of the length of stay after surgery, period of chest draining, and drug cost in DSG were also significantly lower than ISG (P<0.05). Conclusions: Robotic-assisted thoracoscopic day surgery for pulmonary nodule is safe and feasible, with the advantage of short length of stay after surgery, short period of chest draining, less average hospital cost and drug cost. There is no difference in incidence of postoperative complications between DSG and ISG.

Abstract
BACKGROUND Mutations in the neurofibromin 1 (NF1) gene are associated with clinical manifestations of neurofibromatosis type 1 (NF1). OBJECTIVE To clarify the relationship between NF1 variants and disease phenotype. METHODS Peripheral blood samples were collected from a patient and her relatives and genomic DNA was extracted for next-generation sequencing (NGS) to detect potential variants; the results were validated by Sanger sequencing. RESULTS A novel frameshift variant c.4508_c.4509delAT (p.Asn1503fsTer26) was detected in exon 34 of the NF1 gene in the patient and her daughter, but not in any other (healthy) family member. This c.4508_c.4509delAT (p.Asn1503fsTer26) frameshift variant of NF1 may underlie NF1 in this family. CONCLUSIONS This finding expands the spectrum of pathogenic mutations of the NF1 gene, which could aid genetic counseling and prenatal diagnosis.

Abstract
BackgroundHyperuricemia may have a protective role in diseases characterized by high levels of oxidative stress, such as osteoporosis. Previous studies have shown that hyperuricemia is associated with osteoporotic. However, this association is controversial and even yielded conflicting results.ObjectivesThis study investigated the relationship between hyperuricemia and osteoporotic among Chinese adults.MethodsThe data of cross-sectional study was collected at Guangdong Second Provincial General Hospital in Guangzhou City, China between January 2009 and December 2019. Physical examinations and laboratory measurement variables were obtained from the medical check-up system. The multivariate-adjusted logistic regression model was performed to assess the association between hyperuricemia and osteoporotic.ResultsA total of 18917 participants (11334 males and 7579 females) were included in this study, with an average age of 46.23 years (SD: 11.67) at baseline. It included 5881 cases of hyperuricemia and 1587 osteoporotic. After adjusted for the confounding factors in logistic regression analysis, we observed a negative significant association between hyperuricemia and risk of osteoporotic (odds ratio [OR],0.852, 95%CI 0.795–0.967; P <0.05). Further stratified analyses showed a negative significant association with the risk of osteoporotic in women (OR,0.787, 95%CI 0.698–0.853; P <0.05), man (OR,0.897, 95%CI 0.786–0.954; P <0.05) and old adults (OR, 0.808, 95%CI, 0.759-0.894; P <0.05). No significant differences in other groups.ConclusionOur study observed participants with hyperuricemia had significantly less osteoporosis. More high-quality research is needed to further support these findings.References[1]Zong Q, Hu Y, Zhang Q, Zhang X, Huang J, Wang T.

Abstract
BackgroundPrevious studies have observed an increasing trend in the prevalence of hyperuricemia which is linked to the physiological prerequisite for gout in recent years. However, the prevalence of hyperuricemia varies across different populations and different areas.ObjectivesThe aim of this study was to explore the prevalence of hyperuricemia and influencing factors in Chinese adults.MethodsThe analysis was a part of a cross-sectional study in Guangdong Second Provincial General Hospital in Guangzhou City, China between January 2009 and December 2019. A total of 205922 participants (21401 with hyperuricemia) were included in this study. Hyperuricemia was defined as serum uric acid ≥416.0 µmol/L (7.0 mg/dl) for men and ≥357.0 µmol/L(6.0 mg/dl) for women. We calculated the prevalence of hyperuricemia and used the multivariate-adjusted logistic regression model to identify the risk factors associated with hyperuricemia.ResultsThe overall estimated prevalence of HUA was 10.4% in China. Our study showed the prevalence of hyperuricemia in male (10.7%) was higher than that in female (9.9%) (P<0.05). The prevalence of HUA in the age group(≥75) subjects (13.3%) was higher than others. Multivariate logistic regression analysis revealed that sex (OR=1.75), age (OR=1.68), blood urea nitrogen (BUN) (OR=1.051), creatinine (Cr) (OR=1.045), high-density lipoprotein cholesterol (HDL-C) (OR=1.225), low-density lipoprotein cholesterol (LDL-C) (OR=1.466), systolic blood pressure (SBP) (OR=1.012),triglycerides (TG) (OR=1.460) and Body Mass Index (BMI) (OR=1.080) could increase the risk of hyperuricemia, while diastolic blood pressure (DBP) (OR=0.998), fasting plasma glucose (FPG) (OR=0.902) and total cholesterol (TC) (OR=0.704) were associated with a lower risk of hyperuricemia in all adults.ConclusionThe latest prevalence of hyperuricemia is high in Chinese adults and is associated with multiple factors, indicating that prevention and control strategies for hyperuricemia are needed urgently.References[1]Han B, Wang N, Chen Y, Li Q, Zhu C, Chen Y, Lu Y.

Abstract
Purpose To identify the mutations of the NEMO gene in two Chinese females with incontinentia pigmenti. Patients and Methods Patients were both from Nanchong, Sichuan Province. Genomic DNA was extracted from the peripheral blood of patients and patient 1's father. The mutations of the NEMO gene in patient 1 by GAP polymerase chain reaction and Sanger sequencing and her father were detected. NEMO-specific polymerase chain reaction and Sanger sequencing were used to identify the NEMO gene mutation in patient 2. Results DNA analysis identified a rare frameshift mutation, c.723_c.724insCAGG(p.A242QfsX15) in exon 5 of the NEMO gene in patient 1 with a family history but not in her healthy father. The common deletion of exons 4-10 of the NEMO gene was found in sporadic patient 2. Conclusion Our data revealed that the rare frameshift mutation, c.723_c.724insCAGG(p.A242QfsX15) in exon 5 of the NEMO gene in patient 1 and the deletion of exons 4-10 of the NEMO gene in patient 2 could cause the occurrence of IP. Genetic testing is helpful for early diagnosis and genetic counseling for families.

Abstract
Background Station 253 node dissection with high ligation of the inferior mesenteric artery (IMA) is difficult to perform without damage to the surrounding autonomic nerve plexuses. This study aimed to investigate the significance of the nerve plane for inferior mesenteric plexus (IMP) preservation in laparoscopic rectal cancer surgery. Methods A total of 56 consecutive rectal patients underwent laparoscopic en bloc station 253 node dissection with high ligation of the IMA. Station 253 nodes were divided into the extra- and intra-nerve plane station 253 nodes for further H&E staining and immunohistochemical analysis. Based on IMP nerve plane-based evidence and histopathological results, a novel nerve-sparing technique, IMP nerve plane orientation, was proposed and performed on 68 rectal cancer patients. Urinary and sexual functions in all patients were evaluated at 6 months postoperatively. Results Lymph node metastasis was not found, but abundant nerve bundles containing gangliocytes were observed in extra-nerve plane station 253 nodes. The nerve plane was identified intraoperatively and then confirmed by both postoperative gross specimen evaluation and histopathological analysis. The novel nerve-sparing technique (IMP nerve plane orientation) was successfully performed with no postoperative complications, and the operated patients had improved postoperative urinary and sexual functions. Conclusion The nerve plane is helpful for IMP preservation and station 253 node dissection. This novel nerve-sparing technique of nerve plane orientation is technically feasible and safe, which could result in faster recovery of urinary and sexual functions.
