Abstract
Hemorrhagic pleural effusion (PE) is common in clinical practice. According to the guidelines, the etiological diagnosis of PE should focus on the identification of common diseases. In most cases, the etiology of PE can be determined by clinical history, physical examination, laboratory and imaging examinations, and pleural biopsy or video-assisted thoracic surgery (VAST). We reported a rare case of a 32-year-old woman with recurrent unilateral hemorrhagic pleural effusion (highly correlated with menstrual cycle) and chest pain that was diagnosed as thoracic endometriosis syndrome (TES) by pathological biopsy and immunohistochemistry. Later she underwent surgery combined with hormone therapy. During the follow-up, the right PE decreased, and she had no chest pain. Therefore, women of reproductive age with regular unilateral bloody pleural effusions should be alert to TES.

Abstract
Artificial electronic kagome lattices may emerge from electronic potential landscapes using customized structures with exotic supersymmetries, benefiting from the confinement of Shockley surface-state electrons on coinage metals, which offers a flexible approach to realizing intriguing quantum phases of matter that are highly desired but scarce in available kagome materials. Here, we devise a general strategy to construct varieties of electronic kagome lattices by utilizing the on-surface synthesis of halogen hydrogen-bonded organic frameworks (XHOFs). As a proof of concept, we demonstrate three XHOFs on Ag(111) and Au(111) surfaces, which correspondingly deliver regular, breathing, and chiral breathing diatomic-kagome lattices with patterned potential landscapes, showing evident topological edge states at the interfaces. The combination of scanning tunnelling microscopy and noncontact atomic force microscopy, complemented by density functional theory and tight-binding calculations, directly substantiates our method as a reliable and effective way to achieve electronic kagome lattices for engineering quantum states.

Abstract
Objective: The aim of this study was to evaluate the impact of neoadjuvant radiotherapy on anorectal function of patients with mid-low rectal cancer by means of high-resolution anorectal manometry. Methods: A retrospective observational study was conducted. Information on patients with mid-low rectal cancer was collected from the prospective registry database of Rectal Cancer at Peking Union Medical College Hospital (PUMCH) from June 2020 to April 2023. Anorectal functions were detected using three-dimensional high-resolution manometry system. Logistic regression analysis was performed to identify the factors associated with the changed anorectal manometry. Results: A total of 45 patients with mid-low rectal cancer were included in the study. Thirty-two (71.1%) patients were male, 13 (28.9%) patients were female. The mean age was 60±11 years, and the mean BMI was 23.4±3.7 kg/m2. The mean distance between the lower edge of the tumor and the anal verge was 5.4±1.5 cm. The median size of the tumor was 3.4 (2.9-4.5) cm, and the median circumferential extent of the tumor was 66.0 (45.5-75.0) %. 41 (81.1%) patients were MRI T3-4 and 40 (88.9%) patients were MRI N positive. The resting pressure has a decreasing trend after neoadjuvant radiotherapy (55.3±32.0 mmHg vs. 48.0±28.5 mmHg, t=1.930, P=0.060). There was no significant change in maximum squeezing and the length of the high-pressure zone after neoadjuvant radiotherapy. All volumes describing rectal sensitivity (first sensation, desire to defecate, and maximum tolerance) were lower after neoadjuvant radiotherapy. And maximum tolerance was significantly lower (66.0 [49.0,88.0] ml vs. 52.0 [39.0,73.5] ml, Z=-2.481,P=0.013). Univariate analysis demonstrated that the downstage of N-stage was associated with the decrease in maximum tolerance (OR=6.533, 95%CI:1.254-34.051, P=0.026). Conclusion: Neoadjuvant radiotherapy damages anorectal function by decreasing the resting pressure and rectal sensory threshold of patients. The N-stage downstaging was associated with a decrease in maximum tolerance.

Abstract
Objective: To investigate the application value of computed tomography (CT) examination of lymph node short diameter in evaluating cardia-left gastric lymph node metastasis in thoracic esophageal squamous cell carcinoma (ESCC). Methods: A total of 477 patients with primary thoracic ESCC who underwent surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from January 2013 to December 2017 were collected. All of them underwent McKeown esophagectomy plus complete two-field or three-field lymph node dissection. Picture archiving and communication system were used to measure the largest cardia-left gastric lymph node short diameter in preoperative CT images. The postoperative pathological diagnosis results of cardia-left gastric lymph node were used as the gold standard. Receiver operating characteristic (ROC) curve was used to evaluate the efficacy of CT lymph node short diameter in detecting the metastasis of cardia-left gastric lymph node in thoracic ESCC, and determine the optimal cut-off value. Results: The median short diameter of the largest cardia-left gastric lymph node was 4.1 mm in 477 patients, and the largest cardia-left gastric lymph node short diameter was less than 3 mm in 155 cases (32.5%). Sixty-eight patients had cardia-left gastric lymph node metastases, of which 38 had paracardial node metastases and 41 had left gastric node metastases. The lymph node ratios of paracardial node and left gastric node were 4.0% (60/1 511) and 3.3% (62/1 887), respectively. ROC curve analysis showed that the area under the curve of CT lymph node short diameter for evaluating cardia-left gastric lymph node metastasis was 0.941 (95% CI: 0.904-0.977; P<0.05). The optimal cut-off value of CT examination of the cardia-left gastric lymph node short diameter was 6 mm, and the corresponding sensitivity, specificity and accuracy were 85.3%, 91.7%, and 90.8%, respectively. Conclusion: CT examination of lymph node short diameter can be a good evaluation of cardia-left gastric lymph node metastasis in thoracic ESCC, and the optimal cut-off value is 6 mm.

Abstract
Due to the diversity of molecular building blocks, the two-dimensional (2D) metal-organic frameworks (MOFs) are ideal platforms to realize exotic lattice models in condensed matter theory. In this work, we demonstrate the universal existence of topological corner states in 2D MOFs with a star lattice configuration, and confirm the intriguing higher-order nontrivial topology in the energy window between two Kagome-bands, or between Dirac-band and four-band. Furthermore, combining first-principles calculations and scanning tunneling microscopy measurements, the unique topological corner state is directly identified in monolayer Ni3(HITP)2 (HITP = 2,3,6,7,10,11-hexaiminotriphenylene) grown on the Au(111) substrate. Our results not only illustrate the first organic topological state in the experiments, but also offer an exciting opportunity to study higher-order topology in 2D MOFs with the large insulating band gap.

Abstract
Objective: To compare the safety and clinical efficacy of endoscopic and surgical treatment of patients with delayed iatrogenic bile duct injury (DBDI) with severity (SG) grade 1 to 2. Methods: The clinical data of 129 patients with SG grade 1 to 2 DBDI who received endoscopic or surgical treatment in the First Hospital of Lanzhou University from November 2007 to November 2021 were retrospectively collected. There were 46 males and 83 females,aged (M(IQR)) 54(22)years(range: 21 to 82 years). The baseline data of the two groups were matched 1∶1 by propensity score matching(caliper value was 0.2). Independent sample t test,rank sum test,χ2 test or Fisher exact probability test were used to analyze the data of the two matched groups. Results: There were 48 patients in each of the endoscopic treatment and surgical groups after matching,and there was no difference in general information between the two groups(both P>0.05). The bile duct injury-repair interval and intraoperative anesthesia complications were not statistically significant between the two groups after matching(all P>0.05). Compared with the surgical group, patients in the endoscopic treatment group had significantly shorter operative time(50 (30) minutes vs. 185 (100) minutes, Z=7.675,P<0.01) and postoperative hospital stay(5 (5) days vs. 12 (7) days, Z=5.848, P<0.01).For safety,there was no statistical difference in the incidence of immediate postoperative complications between the two groups with Clavien-Dindo classification of surgical complications<Ⅲ;the incidence of serious postoperative complications (Clavien-Dindo classification of surgical complications≥Ⅲ) was significantly higher in the surgical group than in the endoscopic treatment group(P=0.012). The incidence of long-term postoperative complications was not statistically different between the two groups(28.1% vs. 20.7%,P=0.562). In terms of efficacy,the postoperative liver function indexes of patients in both groups improved significantly compared with the preoperative period and returned to normal or near normal levels; the postoperative infection indexes of both groups showed an increasing trend,but were within the normal range. Of the 96 patients in both groups,61 obtained follow-up,and the follow-up time was (89.4±48.0)months(range: 3 to 165 months),and there was no statistical difference between the two groups(P=0.079). The probability of excellent long-term follow-up (78.1% vs. 86.2%) was not statistically different between the two groups(P=0.412).In patients with Strasberg-Bismuth type E1,the probability of excellent long-term follow-up was higher in the endoscopic treatment group compared with the surgical group(13/14 vs. 2/5,P=0.037). Conclusions: For DBDI patients with SG grade 1 to 2 and bile duct continuity,endoscopy can be used as the first deterministic treatment. The advantages of endoscopic therapy compared to surgery are the lower incidence of postoperative serious complications,and the shorter duration of surgery and postoperative hospital stay.

Abstract
Territorial ecological restoration planning is a carrier process for carrying out territorial space regulation and ecological restoration. However, current urban planning efforts only focus on ecological processes, and fail to coordinate the development of both ecology and society. Taking Shantou, a city in Guangdong Province, as an example, we focused on the identification of ecological restoration nodes and the development of differentiated planning strategies from a comprehensive ecological-social perspective. By considering ecosystem integrity, we extracted the ecological corridors and key points by identifying ecological sources and constructing resistance surfaces, constructed an ecological recreation service evaluation system from the social perspective in terms of recreational allocation and recreational value to identify key areas for recreation services, and obtained different types of ecological restoration strategies by synthesizing the results of ecology and recreation. The results showed that there were 136 ecological corridors and 77 ecological nodes in Shantou, with a total length of 380.58 km. The most important recreation areas were the coastline, several inland bays, and wetland tidal flats, with an area of 33.78 km2 and accounting for 1.6% of the total area. Low-level recreation areas was the largest, accounting for 57.3% of the total area. We proposed the composite strategy of "recreation expansion & fishery development", the connectivity strategy of "ecological construction & corridor connection", and the protection strategy of "vegetation restoration & development restriction". This study would provide a comprehensive analysis path for the ecological protection and restoration planning of coastal cities, and would help promote the practicality and maximizing the comprehensive benefits of territorial ecological restoration planning.

Abstract
Objective: To evaluate the long-term efficacy of laparoscopic-assisted natural orifice specimen extraction surgery (NOSES) colectomy using Cai tube for treating left-sided colorectal cancer. Methods: This was a randomized controlled trial. Inclusion criteria were as follows: preoperative pathological diagnosis of left-sided colorectal adenocarcinoma (rectal, sigmoid colon, descending colon, or left transverse colon cancer with the caudad margin ≥8 cm from the anal margin); preoperative abdominal and pelvic computed tomography (or magnetic resonance imaging) showing maximum tumor diameter <4.5 cm; and BMI <30 kg/m2. Patients with synchronous multiple primary cancers or recurrent cancers, a history of neoadjuvant chemoradiotherapy, preoperative evidence of significant local infiltration, distant metastasis, or complications such as intestinal obstruction and intestinal perforation, or who were not otherwise considered suitable for laparoscopic surgery were excluded. A random number table was used to randomize sequential patients to NOSES surgery using Cai tube (non-assisted incision anal sleeve: patent number ZL201410168748.2) (NOSES group) or traditional laparoscopic-assisted surgery (CLS group). Relevant clinical data of the two groups of patients were analyzed, the main outcomes being disease-free survival, overall survival, overall recurrence rate, and local recurrence rate 5 years after surgery. Results: Patients in both study groups completed the surgery successfully with no requirement for additional surgery. After mean 70 (7-83) months postoperative follow-up, the 5-year overall postoperative survival in the NOSES and CLS groups was 90.0% and 83.3%, respectively (P=0.455); disease free survival was 90.0% and 83.3%, respectively (P=0.455); overall recurrence rate 6.6% and 10.0%, respectively (P=0.625); and local recurrence rate both were 3.3% (P=0.990), respectively. None of these differences was statistically significant. Conclusions: NOSES and CLS have similar long-term efficacy, and NOSES deserves to be used in clinical practice.

Abstract
Objective: To investigate the feasibility of Cai tube-assisted natural orifice specimen extraction surgery (NOSES) in gastrointestinal surgery. Methods: This was a descriptive case-series study. Inclusion criteria: (1) colorectal or gastric cancer diagnosed by preoperative pathological examination or redundant sigmoid or transverse colon detected by barium enema; (2) indications for laparoscopic surgery; (3) body mass index <30 kg/m2 (transanal surgery) and 35 kg/m2 (transvaginal surgery); (4) no vaginal stenosis or adhesions in female patients undergoing transvaginal specimen extraction; and (5) patients with redundant colon aged 18-70 years and a history of intractable constipation for more than 10 years. Exclusion criteria: (1) colorectal cancer with intestinal perforation or obstruction, or gastric cancer with gastric perforation, gastric hemorrhage, or pyloric obstruction; (2) simultaneous resection of lung, bone, or liver metastases ; (3) history of major abdominal surgery or intestinal adhesions; and (4) incomplete clinical data. From January 2014 to October 2022, 209 patients with gastrointestinal tumors and 25 with redundant colons who met the above criteria were treated by NOSES utilizing a Cai tube (China invention patent number:ZL201410168748.2) in the Department of Gastrointestinal Surgery, Zhongshan Hospital, Xiamen University. The procedures included eversion and pull-out NOSES radical resection in 14 patients with middle and low rectal cancer, NOSES radical left hemicolectomy in 171 patients with left-sided colorectal cancer, NOSES radical right hemicolectomy in 12 patients with right-sided colon cancer, NOSES systematic mesogastric resection in 12 patients with gastric cancer, and NOSES subtotal colectomy in 25 patients with redundant colons. All specimens were collected by using an in-house-made anal cannula (Cai tube) with no auxiliary incisions. The primary outcomes included 1-year recurrence-free survival (RFS) and postoperative complications. Results: Among 234 patients, 116 were male and 118 were female. The mean age was (56.6±10.9) years. NOSES was successfully completed in all patients without conversion to open surgery or procedure-related death. The negative rate of circumferential resection margin was 98.8% (169/171) with both two positive cases having left-sided colorectal cancer. Postoperative complications occurred in 37 patients (15.8%), including 11 cases (4.7%) of anastomotic leakage, 3 cases(1.3%) of anastomotic bleeding, 2 cases (0.9%) of intraperitoneal bleeding, 4 cases (1.7%) of abdominal infection, and 8 cases (3.4%) of pulmonary infection. Reoperations were required in 7 patients (3.0%), all of whom consented to creation of an ileostomy after anastomotic leakage. The total readmission rate within 30 days after surgery was 0.9% (2/234). After a follow-up of (18.3±3.6) months, the 1-year RFS was 94.7%. Five of 209 patients (2.4%) with gastrointestinal tumors had local recurrence, all of which was anastomotic recurrence. Sixteen patients (7.7%) developed distant metastases, including liver metastases(n=8), lung metastases(n=6), and bone metastases (n=2). Conclusion: NOSES assisted by Cai tube is feasible and safe in radical resection of gastrointestinal tumors and subtotal colectomy for redundant colon.

Abstract
Objective: To investigate the diagnostic performance of MRI Liver Imaging Reporting and Data System version 2018 in high-risk hepatocellular carcinoma (HCC) patients with intrahepatic parenchymal substantial lesions ≤3.0 cm. Methods: A retrospective analysis was conducted in hospitals between September 2014 to April 2020. 131 pathologically confirmed non-HCC cases with lesions ≤3.0 cm in diameter were randomly matched with 131 cases with lesions ≤3.0 cm in diameter and divided into benign (56 cases), other hepatic malignant tumor (OM, 75 cases), and HCC group (131 cases) in a 1:1 ratio. MRI features of the lesions were analyzed and classified according to LI-RADS v2018 criteria (tie-break rule was applied to lesions with both HCC and LR-M features). Taking the pathological results as the gold standard, the sensitivity and specificity of the LI-RADS v2018 classification criteria and the more stringent LR-5 criteria (with three main signs of HCC at the same time) were calculated for HCC, OM or benign lesions diagnosis. Mann -Whitney U test was used to compare the classification results. Results: The number of cases classified as LR-M, LR-1, LR-2, LR-3, LR-4, and LR-5 in HCC group after applying the tie-break rule were 14, 0, 0, 12, 28, and 77, respectively. There were 40, 0, 0, 4, 17, 14 and 8, 5, 1, 26, 13, 3 cases in benign and OM group, respectively. There were 41 (41/77), 4 (4/14) and 1 (1/3) lesion case in the HCC, OM and benign group, respectively, that met the more stringent LR-5 criteria. The sensitivity of LR-4 combined with LR-5 (LR-4/5) criteria, LR-5 criteria and more stringent LR-5 criteria for HCC diagnosis were 80.2% (105/131), 58.8% (77/131) and 31.3% (41/131), respectively, and the specificity were 64.1% (84/131), 87.0% (114/131) and 96.2% (126/131), respectively. The sensitivity and specificity of LR-M were 53.3% (40/75) and 88.2% (165/187), respectively. The sensitivity and specificity using LR-1 combined with LR-2 (LR-1/2) criteria for the diagnosis of benign liver lesions were 10.7% (6/56) and 100% (206/206), respectively. Conclusions: LR-1/2, LR-5, and LR-M criteria have high diagnostic specificity for intrahepatic lesions with a diameter of ≤3.0 cm. Lesions classified as LR-3 are more likely to be benign. The specificity of LR-4/5 criteria is low, while the more stringent LR-5 criteria has a high specificity for HCC diagnosis.

Abstract
Potassium (K+) is one of the essential macronutrients for plant growth and development. However, the available K+ concentration in soil is relatively low. Plant roots can perceive low K+ (LK) stress, then enhance high-affinity K+ uptake by activating H+-ATPases in root cells, but the mechanisms are still unclear. Here, we identified the receptor-like protein kinase Brassinosteroid Insensitive 1-Associated Receptor Kinase 1 (BAK1) that is involved in LK response by regulating the Arabidopsis (Arabidopsis thaliana) plasma membrane H+-ATPase isoform 2 (AHA2). The bak1 mutant showed leaf chlorosis phenotype and reduced K+ content under LK conditions, which was due to the decline of K+ uptake capacity. BAK1 could directly interact with the AHA2 C terminus and phosphorylate T858 and T881, by which the H+ pump activity of AHA2 was enhanced. The bak1 aha2 double mutant also displayed a leaf chlorosis phenotype that was similar to their single mutants. The constitutively activated form AHA2Δ98 and phosphorylation-mimic form AHA2T858D or AHA2T881D could complement the LK sensitive phenotypes of both aha2 and bak1 mutants. Together, our data demonstrate that BAK1 phosphorylates AHA2 and enhances its activity, which subsequently promotes K+ uptake under LK conditions.

Abstract
Objective: To evaluate the mid-term efficacy of laparoscopic-assisted natural orifice specimen extraction surgery (NOSES) colectomy using the Cai tube in the treatment of left colorectal cancer. Methods: A prospective randomized control trial (China Clinical Trials Registration Number: ChiCTR-OOR-15007060) was performed. Sixty patients with left colorectal cancer at Department of Gastrointestinal Surgery of Zhongshan Hospital from September 2015 to August 2017 were prospectively enrolled. Case inclusion criteria: (1) left colorectal adenocarcinoma (rectal cancer with distance ≥ 8 cm from tumor low margin to anal edge, sigmoid colon cancer, descending colon cancer and left transverse colon cancer) confirmed by preoperative pathology; (2) satisfactory conditions of conventional laparoscopic surgery; (3) maximum diameter of the tumor < 4.5 cm confirmed by preoperative abdominal and pelvic CT or MRI; (4) BMI < 30 kg/m2. Case exclusion criteria: (1) benign lesions, mucinous adenocarcinoma, signet-ring cell carcinoma and other special pathological types of tumors confirmed by preoperative pathological examination; (2) multiple or recurrent cancers; (3) with a history of neoadjuvant chemoradiotherapy; (4) obvious regional infiltration or distant metastasis indicated by preoperative imaging examination; (5) intestinal obstruction, intestinal perforation, etc. Participants were randomly assigned to NOSES group (using the Cai tube) and conventional laparoscopy (CL) group by random number table method. Clinical data between two groups were compared and analyzed, including perioperative conditions, tumor exfoliation cell detection and bacterial culture results of intraperitoneal lavage fluid, postoperative complications (Clavien-Dindo grading), postoperative pain [visual simulation scoring (VAS) assessment], anal function (Kirwan anal function grading assessment), and postoperative 3-year disease-free survival (DFS), overall survival (OS), overall recurrence rate, and local recurrence rate. Results: A total of 60 patients were enrolled, with 30 in the NOSES group and 30 in the CL group. All the patients in the NOSES group successfully completed operation with Cai tube. Baseline data between the two groups were not significantly different (all P>0.05). There were no statistically significant differences between two groups in conversion rate to open surgery, number of lymph node harivested, proximal and distal resection margin of tumor, negative rate of circumferential margin, operation time, blood loss, inflammatory indexes, postoperative anal function, postoperative hospital stay, hospitalization cost, morbidity of postoperative complications (Clavien-Dindo grade II or above) (all P>0.05). Compared to the CL group, the NOSES group had lower maximum postoperative VAS score (2.5±0.3 vs. 5.1±0.4, t=3.187, P<0.01), and fewer use of additional postoperative analgesia [6.7% (2/30) vs. 33.3% (10/30),χ2=6.670, P=0.02]. The postoperative time to gas passage was shorter in the NOSES group [(2.2±1.4) days vs. (3.1±1.2) days,P=0.026]. No tumor cells and bacterial contamination were found in abdominal lavage fluid before and after operation in either group. The anal function at postoperative 3-month of all the patients in the NOSES group was Kirwan grade I to II, while in the CL group, anal function of 2 cases (6.7%) was Kirwan grade III, and of 28 cases was also Kirwan grade I to II, whose difference was not statistically significant (P>0.05). In the NOSES group and the CL group, 3-year DFS was 96.7% and 83.3% (P=0.090), OS was 100% and 90% (P=0.096), overall recurrence rate was 3.3% and 10.0% (P=0.166), and local recurrence rate was 3.3% and 3.3% (P=0.999), respectively, whose differences were not statistically significant (all P>0.05). Conclusions: In the treatment of left colorectal cancer, compared with conventional laparoscopic colectomy, NOSES colectomy using Cai tube exhibits less scar, less postoperative pain, shorter recovery of gastrointestinal function, and similar mid-term outcomes. Given proper surgical indications, the surgical procedure is safe and feasible.

Abstract
Potassium and nitrogen are essential mineral elements for plant growth and development. The protein kinase LKS1/CIPK23 is involved in both K+ and NH4+ uptake in Arabidopsis root. The transcripts of LKS1 can be induced by low K+ (0.1 mM) and high NH4+ (30 mM); however, the molecular mechanism is still unknown. In this study, we isolated the transcription factor STOP1 that positively regulates LKS1 transcription in Arabidopsis responses to both low-K+ and high-NH4+ stresses. STOP1 proteins can directly bind to the LKS1 promoter, promoting its transcription. The stop1 mutants displayed a leaf chlorosis phenotype similar to lks1 mutant when grown on low-K+ and high-NH4+ medium. On the other hand, STOP1 overexpressing plants exhibited a similar tolerant phenotype to LKS1 overexpressing plants. The transcript level of STOP1 was only upregulated by low K+ rather than high NH4+; however, the accumulation of STOP1 protein in the nucleus was required for the upregulation of LKS1 transcripts in both low-K+ and high-NH4+ responses. Our data demonstrate that STOP1 positively regulates LKS1 transcription under low-K+ and high-NH4+ conditions; therefore, LKS1 promotes K+ uptake and inhibits NH4+ uptake. The STOP1/LKS1 pathway plays crucial roles in K+ and NH4+ homeostasis, which coordinates potassium and nitrogen balance in plants in response to external fluctuating nutrient levels.

Abstract
Organismal homeostasis of the essential ion K+ requires sensing of its availability, efficient uptake, and defined distribution. Understanding plant K+ nutrition is essential to advance sustainable agriculture, but the mechanisms underlying K+ sensing and the orchestration of downstream responses have remained largely elusive. Here, we report where plants sense K+ deprivation and how this translates into spatially defined ROS signals to govern specific downstream responses. We define the organ-scale K+ pattern of roots and identify a postmeristematic K+-sensing niche (KSN) where rapid K+ decline and Ca2+ signals coincide. Moreover, we outline a bifurcating low-K+-signaling axis of CIF peptide-activated SGN3-LKS4/SGN1 receptor complexes that convey low-K+-triggered phosphorylation of the NADPH oxidases RBOHC, RBOHD, and RBOHF. The resulting ROS signals simultaneously convey HAK5 K+ uptake-transporter induction and accelerated Casparian strip maturation. Collectively, these mechanisms synchronize developmental differentiation and transcriptome reprogramming for maintaining K+ homeostasis and optimizing nutrient foraging by roots.

Abstract
Objective: To investigate the effect of platelet reactivity and other clinical factors on the postoperative 1-year adverse clinical events in patients who underwent selective percutaneous coronary intervention (PCI) anticoagulated with bivalirudin. Methods: This is a multicenter, retrospective and observational study, enrolling 632 patients at high risk of bleeding adjudicated by operators who underwent selective PCI anticoagulated with bivalirudin and had preoperative thrombelastography (TEG) test results in Fuwai Hospital, Northern Theater General Hospital and Xinxiang Central Hospital between January 2017 and August 2018. Platelet reactivity was tested by TEG and adenosine-induced maximal amplitude (MAADP) was recorded. According to MAADP patients were divided into three groups: low on-treatment platelet reactivity (LTPR) group (MAADP<31 mm, n=229), normal on-treatment platelet reactivity (NTPR) group (31 mm≤MAADP≤47 mm, n=207) and high on-treatment platelet reactivity (HTPR) group (MAADP>47 mm, n=196). The endpoints consisted of major adverse cardiovascular and cerebrovascular events (MACCE) and bleeding events. The definition of MACCE was the composite of all-cause mortality, myocardial infarction, intrastent thrombosis, stroke and revascularization. Bleeding events were defined by bleeding academic research consortium (BARC) type 2, 3 and 5 bleeding. Using multivariate Cox regression to analyze the factors of MACCE and bleeding events in patients underwent selective PCI anticoagulated with bivalirudin. Results: A total of 632 patients were finally enrolled in the study with age of (68.3±10.0) years and there were 423 (66.9%) males. All of 632 patients finished one-year follow-up, and 48 (7.6%) patients occurred MACCE and 11 (1.7%) patients occurred bleeding events. There was not statistically significant difference in the incidence of MACCE (8.3% (19/229) vs. 6.3% (13/207) vs.8.2% (16/196), P=0.68) and bleeding events (1.8% (4/229) vs. 2.9% (6/207) vs. 0.5% (1/196), P=0.17) in LTPR, NTPR and HTPR group. Multivariate Cox regression showed that HTPR was not the independent factor of MACCE (HR=1.25, 95%CI 0.67-2.30, P=0.49), and the history of peripheral vessel disease was the independent risk factor of MACCE (HR=2.47, 95%CI 1.19-5.11, P=0.02). LTPR was not the independent factor of bleeding events (HR=1.35, 95%CI 0.39-4.66, P=0.64), and the independent factors of bleeding events were history of peripheral vessel disease (HR=3.95, 95%CI 1.03-15.22, P=0.05) and hemoglobin (HR=0.96, 95%CI 0.93-0.99, P=0.01). Conclusions: In patients undergoing selective PCI anticoagulated with bivalirudin, there is no significant association between platelet reactivity and postoperative 1-year MACCE or bleeding events. History of peripheral vessel disease is an independent risk factor of MACCE, and history of peripheral vessel disease and decreased hemoglobin are independent risk factors of bleeding events.

Abstract
Objective: To understand the current status of foreign dual-degree programs of Medical Doctor (MD) and Master of Public Health (MPH) and provide evidence-based decision-making reference for promoting the education of high-level applied public health talents in China. Methods: The list of involved institutions and information of foreign MD-MPH dual-degree programs was collected through literature retrieval, online information searching, and additional survey of key figures. We extracted the details of each project regarding professional fields, core competence, length of schooling, teaching and learning arrangement, internship eligibility, and graduation assessment. Python 3.8.0 was used for data cleaning, and the occurrence frequency of related items in each dimension was calculated. Results: A total of 99 MD-MPH programs from 104 foreign institutions were included, among which 97.1% of them were implemented in universities from the United States. The School of Public Health provided 42.4% (42/99) of the programs. Epidemiology was the major discipline set up among most programs, accounting for 12.0% (29/241) of all the specialties involved. Epidemiological research methods, health policy management and practice, and public health practice were the top 3 core competencies to be mastered. Of the 99 programs, 87 gave information on the length of the program, of which 74.7% (65/87) were five years, 6.9% (6/87) were four years, and 18.4% (16/87) included both 4-year and 5-year programs. Conclusions: The international MD-MPH programs were sophisticated and mainly organized by the School of Public Health alone or in conjunction with the School of Medicine. Epidemiology is the core course and competence objective, with a length of 4-5 years. Through learning experience from international MD-MPH programs and the Chinese unique medical development background, China should optimize its medical education system to develop a suitable talent training strategy for MD-MPH dual-degree programs in the new era.

Abstract
Objective: To report a method of visualized saphenous nerve block (VSNB) through minimally invasive far medial-subvastus approach distal to the adductor canal in total knee arthroplasty (TKA), and investigate the effect of VSNB in this way on postoperative pain relief. Methods: A total of 100 patients with knee osteoarthritis were prospectively included from June 2018 to October 2019, 29 males and 71 females, aged 50-87(70±8) years. All patients undergoing TKA through minimally invasive far medial-subvastus approach were randomized to visualized saphenous nerve block combined with periarticular infiltration analgesia group (Group VSNB+PIA) or only periarticular infiltration analgesia group (Group PIA),50 cases in each group. The visual analogue scale (VAS) was used to evaluate the pain degree of patients. Furthermore, the scores of VAS in resting and active state at 4, 8, 12, 24, 48, 72 hours after operation and the proportion of patients receiving parecoxib within 72 hours after operation were compared between the two groups. Results: There was statistically significant difference between the two groups in terms of VAS scores in resting state after surgery(F=15.295,P<0.05).The postoperative VAS scores of Group VSNB+PIA at 4, 8, 12, 24 hours at resting state were 1.3±0.8, 1.4±0.7, 1.7±0.8, 3.1±0.8 respectively, which were all significantly lower than those of Group PIA (1.6±0.9, 1.8±0.8, 2.3±0.9, 3.6±0.8) (P<0.05). The overall difference in terms of VAS scores at active state after surgery was statistically significant between the two groups(F=18.532, P<0.05). The postoperative VAS scores of Group VSNB+PIA at 4, 8, 12, 24 hours at active state were 2.0±0.8, 2.2±0.7, 2.7±0.6, 3.7±0.7 respectively, which were all significantly lower than those of Group PIA (2.3±0.8, 2.7±0.7, 3.3±0.8, 4.4±0.7)(P<0.05). Fourteen percent of patients (7/50) in VSNB+PIA group accepted parecoxib within 72 hours after surgery, which was significantly lower than that in PIA group (34%, 17/50) (P<0.05). Conclusions: It is easy to expose the saphenous nerve beyond the adductor canal through minimally invasive far medial-subvastus approach. The Combination therapy of VSNB+PIA is more effective than the simple per-articular infiltration analgesia in providing pain relief after total knee arthroplasty.

Abstract
BACKGROUND The impact of obstructive sleep apnea (OSA) on subsequent cardiovascular events in patients with acute coronary syndrome (ACS) remains inconclusive. AIM Our aim was to systematically assess the relationship between preexisting OSA and adverse cardiovascular events in patients with newly diagnosed ACS by conducting a systematic review and meta-analysis. METHODS We systematically searched PubMed, EMBASE, and Cochrane library for studies published up to May 1, 2020, that reported any association between OSA and cardiovascular events in patients with newly diagnosed ACS. The main outcomes were a composite of all-cause or cardiovascular death, recurrent myocardial infarction, stroke, repeat revascularization, or heart failure. We conducted a pooled analysis using the random-effects model. We also performed subgroup, sensitivity, heterogeneity analysis, and the assessment of publication bias. RESULTS We identified 10 studies encompassing 3350 participants. The presence of OSA was associated with increased risk of adverse cardiovascular events in newly prognosed ACS (risk ratio [RR] 2.18, 95% confidence interval [CI]: 1.45-3.26, P < .001, I2 = 64%). Between-study heterogeneity was partially explained by a multicenter study (9 single-center studies, RR 2.33 95% CI 1.69-3.19, I2 =18%), and I2 remarkably decreased from 64% to 18%. Moreover, OSA significantly increased the incidence of repeat revascularization (8 studies) and heart failure (6 studies) in patients with newly diagnosed ACS. CONCLUSION Patients with preexisting OSA are at greater risk of subsequent cardiovascular events after onset of ACS. Further studies should investigate the treatment of OSA in patient with ACS.

Abstract
Objective: To explore the characteristics of esophageal motility and clinical presentation in gastroesophageal reflux disease (GERD) patients of different age groups. Methods: This was a case-control study. Confirmed GERD patients in the Department of Gastroenterology of Peking Union Medical College Hospital from January 2015 to September 2018 were enrolled and divided into two groups: elderly group (≥60 years old) and young and middle-aged group (<60 years old). Characteristics of gender, disease course, clinical symptoms, esophageal motility, gastroscopic manifestations and esophageal hiatus function of patients in the two groups were analyzed. Results: A total of 250 patients met the inclusion criteria, with 61 patients in elderly group and 189 in young and middle-aged group. There were no significant differences in gender ((male/female: 24/37 vs 78/111, P>0.05) and disease course((4.9±4.2) years vs(4.5±3.8)years, P>0.05) between the two groups. However, there were significant differences in typical symptoms (acid regurgitation and heartburn) and atypical symptoms (chest pain, cough, foreign body sensation in pharynx, etc.) (typical/atypical symptoms: 35/26 vs 146/43, P<0.01) between the two groups. Compared with young and middle-aged group, upper esophageal sphincter (UES) resting pressure was lower ((65±28) mmHg (1 mmHg=0.133 kPa)vs (74±28) mmHg, P<0.05), but the percentage of ineffective esophageal motility (IEM) (78.7%(48/61) vs 65.1%(123/189),P<0.05) and DeMeester score (16.3(6.0,36.3) vs 6.4(2.5,18.0), P<0.05) were higher in elderly group. There were no significant differences in lower esophageal sphincter (LES) resting pressure and distal contractile integral (DCI) between the two groups. Higher proportion of grade C and D reflux esophagitis,and grade C and D reflux esophagitis complicated with esophageal hiatus dysfunction was observed in elderly group compared with young and middle-aged group (2.04%(8/49) vs 0.65%(1/155); 14.29%(7/49) vs 0(0/155); both P<0.01). Pearson correlation analysis showed that there was a negative correlation between UES resting pressure and age(r=-0.145, P<0.05), while there was a positive correlation between the LES length and age (r=0.129, P<0.05). Conclusion: Compared with young and middle-aged GERD patients, the atypical symptoms, lower LES resting pressure, increased incidence of ineffective esophageal motility and acid exposure were more prominent in the elderly. Considering that anti-reflux function was weakened, long-term acid suppressants may be needed in elderly patients.

Abstract
Objective: To explore the epidemiological characteristics and treatment outcomes of inhalation injury patients combined with burn area less than 30% total body surface area (TBSA) admitted to the First Affiliated Hospital of Naval Medical University. Methods: Retrospective observational study with performed on medical records of 266 inhalation injury patients combined with burn area less than 30% TBSA who were admitted to the First Affiliated Hospital of Naval Medical University from January 2008 to September 2016 and met the inclusion criteria. The gender, age, injured site, injurious factors of inhalation injury, degree of inhalation injury, combined total burn area, way of tracheotomy, time of tracheotomy, whether conducted mechanical ventilation or not, whether in intensive care unit (ICU) or not, microbial culture results of bronchoalveolar lavage, total hospitalization days, ICU days, mechanical ventilation days, and whether respiratory infections occurred or not. Single factor and multivariate linear regression analysis was used to screen out the risk factors impacting the total hospitalization days, ICU days, and mechanical ventilation days of patients. Single factor and multivariate logistic regression analysis was used to screen out the risk factors impacting respiratory infections of patients. Results: The 266 patients included 190 males and 76 females, with the majority age of above and equal to 21 and below 65 years (217 patients). Confined space was the major injured site. Hot air was the major factor of inhalation injury. Mild and moderate inhalation injuries were commonly seen in patients. The combined total burn area was 9.00 (3.25, 18.00) %TBSA. In 111 patients who were conducted with tracheotomy, the most were conducted before admitted to the First Affiliated Hospital of Naval Medical University. The total hospitalization days of patients were 27 (10, 55) days. The ICU days of 160 patients were 15.5 (6.0, 40.0) days. The mechanical ventilation days of 109 patients were 6.0 (1.3, 11.5) days. A total of 119 patients were diagnosed with respiratory infections, with 548 strains including 35 types of pathogens were isolated, mainly of Gram-negative bacteria. Single factor linear regression analysis showed age, injurious factors of inhalation injury, combined total burn area, degree of inhalation injury, way of tracheotomy, whether conducted mechanical ventilation or not, and whether respiratory infections occurred or not were the risk factors impacting the total hospitalization days of patients (95% confidence interval (CI)=-0.397-0.001, -0.395--0.053, 0.015-0.028, 0.009-0.263, 0.008-0.319, -0.419--0.176, 0.242-0.471, 0.340-0.555, P<0.1). Multivariate linear regression analysis showed smoke inhalation, mechanical ventilation, and respiratory infections were the independent risk factors impacting the total hospitalization days of patients (95% CI=-0.384-0.082, 0.022-0.271, 0.261-0.506, P<0.05 or P<0.01). Single factor linear regression analysis showed injurious factors of inhalation injury, combined total burn area, degree of inhalation injury, way of tracheotomy, whether conducted mechanical ventilation or not, and whether respiratory infections occurred or not were the risk factors impacting the ICU days of patients (95% CI=0.053-0.502, 0.006-0.010, -0.018-0.457, -0.022-0.428, -0.575--0.241, -0.687--0.018, 0.132-0.486, 0.369-0.678, P<0.1). Multivariate linear regression analysis showed that no tracheotomy and respiratory infections were the independent risk factors impacting the ICU days of patients (95% CI=-0.414--0.084, 0.278-0.601, P<0.01). Single factor linear regression analysis showed injured site, injurious factors of inhalation injury, combined total burn area, degree of inhalation injury, way of tracheotomy, and whether respiratory infections occurred or not were the risk factors impacting mechanical ventilation days of patients (95% CI=-0.565--0.034, 0.145-0.946, 0.051-1.188, 0.001-0.009, 0.127-0.847, 0.436-1.162, -1.243--0.229, 0.005-0.605, P<0.1). Multivariate linear regression analysis showed open space inhalation, smoke inhalation, severe inhalation injury, no tracheotomy, prophylactic tracheotomy, and respiratory infections were the independent risk factors impacting mechanical ventilation days of patients (95% CI=-0.588--0.127, 0.138-0.560, 0.143-0.848, -0.909--0.330, -1.008--0.015, 0.007-0.519, P<0.05 or P<0.01). Single factor logistic regression analysis showed age, injured site, degree of inhalation injury, combined total burn area, way of tracheotomy, and whether conducted mechanical ventilation or not were the risk factors impacting respiratory infections of patients (95% CI=0.840-1.362, 0.641-1.044, 1.122-1.526, 1.028-1.661, 1.344-2.405, 1.460-2.612, 0.744-1.320, 0.241-0.424, 2.331-4.090, P<0.1). Multivariate logistic regression analysis showed prophylactic tracheotomy, no tracheotomy, and mechanical ventilation were the independent risk factors impacting respiratory infections of patient (95% CI=0.430-0.641, 0.290-0.511, 2.152-8.624, P<0.05 or P<0.01). Conclusions: The inhalation injury patients combined with burn area less than 30% TBSA are mainly young and middle-aged males. Confined space, smoke inhalation, mechanical ventilation, respiratory infection, and way of tracheotomy are influencing factors of the outcomes in hospital of inhalation injury patients combined with burn area less than 30% TBSA. Additionally, prophylactic tracheotomy shows its potential role in avoiding respiratory infection for patients with moderate or severe degree of inhalation injury.

Abstract
The two-dimensional (2D) twisted bilayer materials with van der Waals coupling have ignited great research interests, paving a new way to explore the emergent quantum phenomena by twist degree of freedom. Generally, with the decreasing of twist angle, the enhanced interlayer coupling will gradually flatten the low-energy bands and isolate them by two high-energy gaps at zero and full filling, respectively. Although the correlation and topological physics in the low-energy flat bands have been intensively studied, little information is available for these two emerging gaps. In this Letter, we predict a 2D second-order topological insulator (SOTI) for twisted bilayer graphene and twisted bilayer boron nitride in both zero and full filling gaps. Employing a tight-binding Hamiltonian based on first-principles calculations, three unique fingerprints of 2D SOTI are identified, that is, nonzero bulk topological index, gapped topological edge state, and in-gap topological corner state. Most remarkably, the 2D SOTI exists in a wide range of commensurate twist angles, which is robust to microscopic structure disorder and twist center, greatly facilitating the possible experimental measurement. Our results not only extend the higher-order band topology to massless and massive twisted moiré superlattice, but also demonstrate the importance of high-energy bands for fully understanding the nontrivial electronics.

Abstract
Pesticides are among the most widespread organic contaminants in aquatic environments. In this work, a new green fluorescence application was proposed for the simultaneous determination of four widely employed pesticides in environmental water samples. To overcome the highly overlapped spectra within the analytes, and with the tissue matrix interferences in complex solutions, we have used the multivariate calibration methods such as parallel factor analysis (PARAFAC) and unfolded partial least squares coupled to residual bilinearization (U-PLS/RBL). These four pesticides can be identified simultaneously, and the correlation coefficients between resolved and actual spectra are all above 0.95. The second-order advantage allowed the determination of four pesticides at the ng mL-1 level, even in the presence of humic acid (HA). The best results were obtained with the limits of detection of 1.72-18.69 for Carbendazim (CBZ), 0.30-5.19 for carbaryl (CAR), 0.35-6.32 for chlorothalonil (CHL), and 4.92-29.96 for tsumacide (TSU) (ng mL-1), which can fully meet the quantitative detection and analysis requirements of trace pesticides in water samples. The real water sample of Bohai Seawater was used to check the performance of this approach in practical applications, which have achieved good prediction results of U-PLS/RBL. This study demonstrated the proposed method is rapid, accurate, sensitive, low detection limit, and environmentally friendly to determinate multi-pesticide residues in environmental water samples.

Abstract
Background: Mesenchymal stem or stromal cells (MSCs) derived from the induced pluripotent stem cells (iPSCs) have uniform biological activity, which makes the clinical application of MSCs in bone repair possible. Culturing the iPSC-MSCs onto osteoconductive materials is a promising tissue engineering-based strategy in bone regeneration. The aim of this work was to evaluate the effects of semaphorin 3A (Sema3A) and hypoxia inducible factor 1 subunit alpha (HIF1α) co-overexpression on the survival and osteogenic differentiation of iPSC-MSCs. Methods: Sema3A and HIF1α were linked together with the three (GGGGS; G, glycine; S, serine) peptide fragment, and their co-expression in iPSC-MSCs was mediated by a lentiviral vector. The fusion protein retained the immune reactivity for both Sema3A and HIF1α as determined with Western blotting. iPSC-MSCs were infected with overexpression lentivirus (oeLenti) as negative control, oeLenti-Sema3A, oeLenti-HIF1α or oeLenti-Sema3A-HIF1α lentiviruses. Results: Sema3A overexpression alone promoted the osteogenic differentiation of iPSC-MSCs (the activity and/or expression of osteoblast markers, such as alkaline phosphatase, osteopontin, and osteocalcin, were upregulated), and suppressed cell survival. The Sema3A-HIF1α fusion protein showed a comparable osteoconductive effect to that of Sema3A without reducing cell survival. We further seeded iPSC-MSCs modified by SemaA-HIF1α overexpression onto hydroxyapatite (HA) scaffolds, and evaluated their growth and differentiation on this three-dimensional material. Additional data indicated that, as compared to iPSC-MSCs cultured in ordinary two-dimensional dishes, cells cultured in HA scaffolds grew (blank vs. HA scaffolds: 0.83 vs. 1.39 for survival) and differentiated better (blank vs. HA scaffolds: 11.29 vs. 16.62 for alkaline phosphatase activity). Conclusion: Modifying iPSC-MSCs with pro-osteogenic (Sema3A) and pro-survival (HIF1α) factors may represent a promising strategy to optimize tissue engineering-based strategy in bone repair.

Abstract
Objective: To explore the feasibility and safety of a newly developed simple and rapid axillary vein puncture technique based on the surface landmarks for pacemaker implantation. Methods: From January to November 2018, we enrolled 110 patients who underwent pacemaker implantation in Beijing Anzhen Hospital. Basic clinical characteristics, such as gender, age, major diagnosis, type of pacemaker, and His-purkinje system pacing, were collected. The success rate of this axillary vein puncture technique, complications, and technical parameters of present puncture method were analyzed. Results: There were 58 (52.7%) male patients in this cohort and the average aged was (70.26±10.45) years old. This "blind" axillary vein puncture method was successful in 105 out of 110 patients (95.5%). The relevant puncture-related parameters included: the distance between points "a and b" was (3.89±0.40) cm, the first angle α was (25.84±5.54)° and the second angle β was (66.18±10.26)°. There were no puncture-related complications, such as hematoma, pneumothorax and hemothorax. Conclusion: The new "blind" axillary vein puncture approach is a simple, effective and safe technique for pacemaker implantation, which is easy to learn and practice and suitable for promotion.

Abstract
The hourglass fermion, as an exotic quasiparticle protected by nonsymmorphic symmetry, has excited great research interest recently. However, its bulk counterpart in two-dimensional (2D) solid-state materials has seldom been studied. In this Letter, we propose a 2D rectangular lattice made of p_{x} and p_{y} orbitals with glide mirror symmetry but without inversion symmetry to realize the hourglass fermion. The glide mirror symmetry guarantees a Dirac nodal line, while the Rashba spin-orbital coupling splits it into two Weyl nodal lines and generates two pairs of hourglass fermion located at the glide mirror plane. Furthermore, based on first principles calculations, we predict a surface-supported 2D material Bi/Cl-SiC(111) to realize our proposal, making a huge-bandwidth hourglass cone. Moreover, the hourglass fermion exhibits a spin-momentum locking spin texture and also sustains a giant spin Hall conductivity. Our results demonstrate a general routine for designing an hourglass fermion in 2D materials, which will be easily extended to other surfaces with different adatoms and lattice symmetries.

Abstract
Two-dimensional quadrupole topological insulator (2D QTI), as a new class of second-order topological phases, has been experimentally confirmed in various artificial systems recently. However, its realization in electronic materials has seldom been reported. In this work, we predict that the experimentally synthesized γ-graphyne is a large-gap (∼0.2 eV) 2D QTI. Three characterized features for 2D QTI are simultaneously observed in γ-graphyne: quantized finite bulk quadrupole moment, gapped topological edge states, and in-gap topological corner states. Intriguingly, we found that gapped topological edge states exist on armchair edge with C≡C (but not C-C) termination, and in-gap topological corner states exist at corner with 120° (but not 60°) termination, which can be explained by different edge-hopping textures and corner chiral charges. Moreover, the robustness of in-gap topological corner states is further identified by varying edge-disorder and system-size calculations. Our results demonstrate a realistic electronic material for large-gap 2D QTI, which is expected to draw immediate experimental attention.

Abstract
So far, most theoretically predicted and experimentally confirmed quantum anomalous Hall effects (QAHEs) are limited in two-dimensional (2D) materials with out-of-plane magnetization. In this Letter, starting from 2D nodal-line semimetal, a general rule for searching QAHE with in-plane magnetization is mapped out. Because of spin-orbital coupling, we found that the magnetization will prefer an in-plane orientation if the orbital of degenerate nodal-line states at the Fermi level have the same absolute value of magnetic quantum number. Moreover, depending on the broken or conserved mirror symmetry, either a QAHE or 2D semimetal can be realized. Based on first principles calculations, we further predict a real material of monolayer LaCl to be an intrinsic QAHE with in-plane magnetization. By tuning the directions of in-plane magnetization, the QAHE in LaCl demonstrates a threefold rotational symmetry with a Chern number of either +1 or -1, and the transition point is characterized by a 2D semimetal phase. All these features are quantitatively reproduced by tight-binding model calculations, revealing the underlying physics clearly. Our results greatly extend the scope for material classes of QAHE and hence stimulate immediate experimental interest.

Abstract
Objective: To master the status of ophthalmic human resource allocation and service delivery at county level in Mainland China, and to provide the basis for strengthening the construction of grassroots ophthalmic personnel team and formulating feasible medium and long-term eye health plans. Methods: All the medical institutions that provided ophthalmic service at county level or above were investigated by online reporting. This study only included medical institutions at county level. Descriptive statistics were used. Results: Three thousand three hundred and fifty-nine medical institutions were included, of which 1 463 hospitals had independent departments of ophthalmology (43.55%). Each medical institution has 3.93 ophthalmologists, 4.59 ophthalmic nurses, 0.30 full-time optometrist and 0.21 full-time optician. Ophthalmologists are mainly undergraduate, and the ratio of senior, intermediate and junior titles is 1.0∶1.7∶1.9. The ophthalmic nurses are mainly graduated from junior colleges or secondary schools, and the ratio of senior, intermediate and junior titles is 1.0∶7.3∶22.3. There were statistically differences in the distribution of job titles of ophthalmologists (χ(2)=106.21, P<0.01) and nurses (χ(2)=128.54, P<0.01) in the eastern, central and western regions. Of each ophthalmologist, the annual number of outpatient, outpatient surgery, inpatient and inpatient operation was 2 377.62, 109.79, 124.03, and 85.97 respectively. Four thousand one hundred and sixty ophthalmologists were able to carry out cataract surgeries independently, accounting for 31.50% of all ophthalmologists. The quantity for annual per capita cataract operation among ophthalmologists who can perform cataract surgery independently was 181.81 per capita. The average beds rate of utilization was 68.91%, and that was less than 60% in 52.99% of medical institutions. Conclusions: Compared with 1998, ophthalmic health personnel at county level in Mainland China has expanded rapidly. But cataract ability of ophthalmologists and the number of cataract surgeries still need to be improved. The structure of ophthalmic nursing staff is irrational. The full-time optometrists and opticians are extremely scarce. It is necessary to cultivate high-quality ophthalmic health personnel and improve beds rate of utilization at county level.

Abstract
Objective: To evaluate the efficacy and safety of testa triticum tricum purif for the treatment of functional constipation(FC) in the late middle-aged and elderly patients. Methods: This study was designed as a multicenter randomized controlled trial. Patients who met Rome Ⅲ diagnostic criteria of FC were enrolled, with age between 55-85 years old. Those with organic diseases were excluded. The patients were randomly allocated to receive testa triticum tricum purif (3.5 g bid) or polyethylene glycol 4000 powder (PEG4000, 10g bid) for 8 weeks, followed by single dose of maintenance therapy for 4 weeks. Follow-up visits were at 4 and 12 weeks after treatment discontinuation. The independent investigators in each center evaluated the constipation symptoms scores. The primary endpoints included rates of significant improvement, improvement and overall improvement at the end of 2, 4 and 8 weeks of therapy, which were calculated by the reduction of symptom scores ≥75%, 50%-74%, ≥25% respectively. Results: A total of 127 FC subjects were enrolled from 3 centers, and 122 cases valid for final analysis. The mean age was (69.4±6.9) years old, including 62 cases in testa triticum tricum purif group and 60 cases in PEG4000 group. The demographic data, constipated symptoms scores and proportion of FC subtypes at baseline were comparable. The rates of significant improvement, improvement and overall improvement in testa triticum tricum purif and PEG4000 groups at the end of 2, 4 and 8 weeks were 37.70% (23/61) vs 59.32% (35/59) (P=0.018), 57.38% (35/61) vs 74.14% (43/58) (P=0.054), and 64.41% (38/59) vs 79.31% (46/58) (P=0.073) respectively. Testa triticum tricum purif therapy significantly improved the proportion of spontaneous bowel movement(SBM) ≥3 times/week from 43.55% (27/62) to 80.33% (49/61), 83.61% (51/61) and 93.22% (55/59) at 2, 4, and 8 weeks respectively (all P<0.01), which were comparable with PEG4000 group (all P>0.05). The proportion of normalized stool forms in study group was significant higher than that of control group at the end of 8 weeks [86.44% (51/59) vs 67.24% (39/58), P=0.014]. Only one patient complained mild abdominal distension during testa triticum tricum purif therapy. Conclusions: The efficacy of testa triticum tricum purif for the treatment of FC in late middle-aged and older patients is comparable with osmotic laxatives PEG4000, which has significant effect on normalization of fecal forms and reliable safety.

Abstract
Objective: To investigate the effect of excimer laser coronary atherectomy (ELCA) in the interventional treatment of acute coronary syndrome (ACS). Methods: This prospective study enrolled 31 patients with ACS who underwent ELCA treatment in our hospital from November 8, 2016 to December 13, 2017. The efficacy and complications of ELCA were observed, and patients were followed up for postoperative observation of major adverse cardiovascular and cerebrovascular events (including target vessel revascularization, stroke, stent thrombosis, coronary artery bypass grafting, and death). Results: The patients were aged (65.0±10.8) years old and 25 were males (80.6%).There were 5 cases (16.1%) ST-segment elevation myocardial infarction, 3 cases (9.7%) non-ST-segment elevation myocardial infarction, and 23 cases (74.2%) unstable angina in this cohort.There were 9 cases (29.0%) in-stent restenosis, 11 cases (35.5%) saphenous vein graft, 2 cases (6.5%) chronic total occlusive disease, and 4 cases (12.9%) calcification.Two patients with chronic complete occlusive disease and 1 patient with calcified lesion were examined by intravascular ultrasound (IVUS). The other lesions were not examined with IVUS and optical correlation tomography (OCT).The ELCA success rate was 100% (31/31) and the PCI success rate was 100% (31/31).Intraoperative use of 0.9 mm diameter catheters accounted for 38.7% (12/31), 1.7 mm diameter catheters accounted for 32.3% (10/31), and 1.4 mm diameter catheters accounted for 29.0% (9/31).One patient with ST-segment elevation myocardial infarction experienced no reflow of coronary artery during operation. The other 30 patients had no complications such as perforation, small dissection, large dissection, distal occlusion, slow blood flow and collateral occlusion. One cardiac death(3.2%) occurred during the postoperative follow-up of (6.4±1.9) months. Conclusion: Our preliminary study results indicate that the use of ELCA in the interventional therapy of ACS is safe and effective.

Abstract
Since the discovery of graphene, two-dimensional (2D) materials have paved new ways to design high-performance nanoelectronic devices. To facilitate applications of such devices, there are three key requirements that a material needs to fulfill: sizeable band gap, high carrier mobility, and robust environmental stability. However, among the most popular 2D materials studied in recent years, graphene is gapless, hexagonal boron nitride has a very large band gap, transition metal dichalcogenides have low carrier mobility, and black phosphorene is ambience-sensitive. Thus far, these three characteristics could seldom be satisfied by only a single material. Therefore, it is a great challenge to find an ideal 2D material that can overcome these limitations. In this study, we theoretically predicted a novel planar 2D material penta-Pt2N4, which was designed using the Cairo pentagonal tiling as well as the rare nitrogen double bonds. Most significantly, 2D penta-Pt2N4 exhibits excellent intrinsic properties, including large direct band gap (up to 1.51 eV), high carrier mobility (up to 105 cm2·V-1·s-1), very high Young's modulus (up to 0.70 TPa), and robust dynamic, thermal, and ambient stabilities. Moreover, penta-Pt2N4 is the global minimum structure among 2D materials with PtN2 stoichiometry. We also propose a CVD/MBE scheme to enable its experimental synthesis. We envision that 2D penta-Pt2N4 may find wide applications in the field of nanoelectronics.

Abstract
Coupling a quantum anomalous Hall (QAH) state with a superconducting state offers an attractive approach to detect the signature alluding to a topological superconducting state [Q. L. He et al., Science 357, 294 (2017)SCIEAS0036-807510.1126/science.aag2792], but its explanation could be clouded by disorder effects in magnetic doped QAH materials. On the other hand, an antiferromagnetic (AFM) quantum spin Hall (QSH) state is identified in the well-known high-temperature 2D superconductor of monolayer FeSe [Z. F. Wang et al., Nat. Mater. 15, 968 (2016)NMAACR1476-112210.1038/nmat4686]. Here, we report a light-induced type-II band inversion (BI) and a QSH-to-QAH phase transition in the monolayer FeSe. Depending on the handedness of light, a spin-tunable QAH state with a high Chern number of ±2 is realized. In contrast to the conventional type-I BI resulting from intrinsic spin-orbital coupling (SOC), which inverts the band an odd number of times and respects time reversal symmetry, the type-II BI results from a light-induced handedness-dependent effective SOC, which inverts the band an even number of times and does not respect time reversal symmetry. The interplay between these two SOC terms makes the spin-up and -down bands of an AFM QSH state respond oppositely to a circularly polarized light, leading to the type-II BI and an exotic topological phase transition. Our finding affords an exciting opportunity to detect Majorana fermions in one single material without magnetic doping.

Abstract
Objective: To investigate the osseointegration of a novel coating-plasma-sprayed zirconia in dental implant. Methods: Zirconia coating on non-thread titanium implant was prepared using plasma spraying, the implant surface morphology, surface roughness and wettability were measured. In vivo, zirconia coated implants were inserted in rabbit tibia and animals were respectively sacrificed at 2, 4, 8 and 12 weeks after implantation. The bond strength between implant and bone was measured by push-out test. The osseointegration was observed by scanning electron microscopy (SEM), micro CT and histological analyses. Quantified parameters including removal torque, and bone-implant contact (BIC) percentage were calculated. Results: The surface roughness (1.6 µm) and wettability (54.6°) of zirconia coated implant was more suitable than those of titanium implant (0.6 µm and 74.4°) for osseointegration. At 12 weeks, the push-out value of zirconia coated implant and titanium implant were (64.9±3.0) and (50.4±2.9) N, and BIC value of these two groups were (54.7±3.6)% and (41.5±3.6)%. All these differences had statistical significance. Conclusions: The surface characters of zirconia coated implant were more suitable for osseointegration and present better osseointegration than smooth titanium implant in vivo, especially at early stage.

Abstract
OBJECTIVE To investigate serum IgG4 levels in different diseases and the changes of serum IgG4 levels in post treatment of IgG4 related disease. METHODS Clinical data of 620 patients who received investigation of serum IgG4 in Peking University People's Hospital from January 1, 2015 to March 31, 2016 were collected retrospectively. According to the difference of the diseases, they were divided into common group of diseases, autoimmune diseases and IgG4 related diseases; pancreatic disease patients were divided into autoimmune pancreatitis and pancreatic cancer group; According to different treatment stages of the disease, the patients with IgG4 related diseases were divided into pretreatment group and post treatment group. And the expressions of the patients'serum IgG4 levels in different groups were analyzed. RESULTS The median serum IgG4 level in the group of the patients with common diseases was 0.480(0.005, 50.400) g/L, in the group of autoimmune disease was 0.406 (0.003, 18.700) g/L , in the group of IgG4 related diseases was 5.200(0.046, 46.000)g/L, which was signi-ficantly higher in the group of IgG4 related diseases than the other two groups, and there was obvious statistical significance in serum IgG4 levels between the group of IgG4 related diseases and the other two groups (P<0.01); There was no obvious difference in serum IgG4 levels between the common disease group and the autoimmune disease group, and there was no obvious statistical difference in serum IgG4 levels between the two groups (P>0.05). In the patients with IgG4 related diseases, the median serum IgG4 level in the group of pretreatment patients was 6.540 (1.330, 34.100) g/L, and 3.735 (0.063, 46.000) g/L in the post treatment patients. Serum IgG4 levels decreased in post treatment group, signi-ficantly lower than in pretreatment, there was obvious statistical difference in serum IgG4 levels between the two groups (P<0.01). The median serum IgG4 level in the group of patients with autoimmune pancreatitis was 3.735 (0.063, 46.000) g/L ,and 0.438 (0.056, 1.130) g/L in the group of patients with pancreatic cancer,which was significantly higher in the group of patients with autoimmune pancreatitis than the others, and there was obvious statistical difference in serum IgG4 levels between the two groups (P<0.01). CONCLUSION Serum IgG4 levels in patients with different diseases were different, and were significantly higher in patients with autoimmune pancreatitis and IgG4 related diseases, so serum IgG4 levels can provide the basis for the differential diagnosis of different diseases; Serum IgG4 levels in patients with IgG4 related diseases decrease significantly after treatment, so it can be used as an important index to evaluate the curative effect of IgG4 related diseases.

Abstract
Objective: To investigate the correlation between TNM staging of primary cholangiocarcinoma and the maximum standard uptake value (SUVmax) of (18)F-2-deoxy-D-glucose positron emission tomography with computerized tomography ((18)F-FDG PET/CT). Methods: A retrospective analysis of 36 patients with confirmed primary cholangiocarcinoma from October 2014 to July 2016 was carried out. All the patients underwent preoperative PET/CT in the Fifth Affiliated Hospital of Wenzhou Medical University from November 2014 to July 2016, the SUVmax was calculated by drawing region of interest around the primitive tumor area.According to the American Cancer Joint Committee (AJCC) guidelines for the clinical staging of intrahepatic and extrahepatic cholangiocarcinoma, the differences of SUVmax were compared in the patients with different age, gender and staging, and the correlation between TNM staging and SUVmax was determined.Data were compared with independent sample t test between groups. Results: The mean SUVmax of 36 patients with primary cholangiocarcinoma was 7.87±3.17 (2.1-14.6). The SUVmax values of patients with lymph node metastasis or distant metastasis were significantly higher than those without lymph node metastasis or distant metastasis (t=0.364, 0.343, both P<0.05), respectively. There was significant difference in SUVmax between patients with different TNM staging (F=1.352, P=0.021). There was no significant differences in SUVmax between patient with different gender, age (>70 years or<70 years) and T staging (t=1.058, 1.980, F=1.252, all P>0.05). Spearman correlation analyses showed that the TNB stage of primary cholangiocarcinoma was positively correlated with its SUVmax (r=0.658, P=0.007). Conclusion: The SUVmax is positively correlated with the TNM staging of primary cholangiocarcinoma, which is helpful for the clinical staging and prognosis of the patients.

Abstract
Potassium and nitrogen are essential macronutrients for plant growth and have a positive impact on crop yield. Previous studies have indicated that the absorption and translocation of K+ and NO3- are correlated with each other in plants; however, the molecular mechanism that coordinates K+ and NO3- transport remains unknown. In this study, using a forward genetic approach, we isolated a low-K+-sensitive Arabidopsis thaliana mutant, lks2, that showed a leaf chlorosis phenotype under low-K+ conditions. LKS2 encodes the transporter NRT1.5/NPF7.3, a member of the NRT1/PTR (Nitrate Transporter 1/Peptide Transporter) family. The lks2/nrt1.5 mutants exhibit a remarkable defect in both K+ and NO3- translocation from root to shoot, especially under low-K+ conditions. This study demonstrates that LKS2 (NRT1.5) functions as a proton-coupled H+/K+ antiporter. Proton gradient can promote NRT1.5-mediated K+ release out of root parenchyma cells and facilitate K+ loading into the xylem. This study reveals that NRT1.5 plays a crucial role in K+ translocation from root to shoot and is also involved in the coordination of K+/NO3- distribution in plants.

Abstract
Dracontomelon duperreanum, the most representative species of the family Anacardiaceae, is an important multipurpose tree in China and Vietnam. However, no genetic diversity studies have been reported on this species. In this study, we identified 11 microsatellite markers for D. duperreanum by using the restriction-site-associated DNA sequencing (RAD-seq) method and examined their polymorphisms in 22 samples obtained from the South China Botanical Garden, South China. We could detect only two or three alleles for each microsatellite marker. The mean observed and expected heterozygosities were 0.41 and 0.39, respectively, which were lower than those reported for the species with similar life history forms. These relatively low genetic diversities in this common plant species are unexpected and might have resulted from its extensive cultivation. To our knowledge, this is the first report of microsatellite markers in the genus Dracontomelon. These microsatellite markers will be valuable for studying the genetic diversities and structures in D. duperreanum and other Dracontomelon species.

Abstract
Chinese tallow (Triadica sebifera) is an important crop and ornamental tree. After it was introduced into the USA, it gradually became a noxious invasive tree in south-eastern America since the middle of the 1900s. Because only six microsatellites were reported previously in T. sebifera, to better understand the genetic diversity and population dynamics of such species, we reported here 28 new microsatellite markers. For these 28 microsatellites, the number of alleles per locus ranged from 2-16. The expected heterozygosity and the expected heterozygosity corrected for sample size varied from 0.0796 to 0.9081 and from 0.0805 to 0.9176, respectively. These microsatellites will provide additional choice to investigate the genetic diversity and structure in T. sebifera.

Abstract
This study represents the first report of a C-type lectin (ctl) in yellow catfish Tachysurus fulvidraco. The complete sequence of ctl complementary (c)DNA consisted of 685 nucleotides. The open reading frame potentially encoded a protein of 177 amino acids with a calculated molecular mass of c.y 20.204 kDa. The deduced amino-acid sequence contained a signal peptide and a single carbohydrate recognition domain with four cysteine residues and GlnProAsp (QPD) and TrpAsnAsp (WND) motifs. Ctl showed the highest identity (56.0%) to the predicted lactose binding lectin from channel catfish Ictalurus punctatus. Quantitative real-time (qrt)-PCR analysis showed that ctl messenger (m)RNA was constitutively expressed in all examined tissues in normal fish, with high expression in trunk kidney and head kidney, which was increased following Aeromonas hydrophila challenge in a duration-dependent manner. Purified recombinant Ctl (rCtl) from Escherichia coli BL21 was able to bind and agglutinate Gram-positive and Gram-negative bacteria in a calcium-dependent manner. These results suggested that Ctl might be a C-type lectin of T. fulvidraco involved in innate immune responses as receptors (PRR).

Abstract
Superconducting and topological states are two most intriguing quantum phenomena in solid materials. The entanglement of these two states, the topological superconducting state, will give rise to even more exotic quantum phenomena. While many materials are found to be either a superconductor or a topological insulator, it is very rare that both states exist in one material. Here, we demonstrate by first-principles theory as well as scanning tunnelling spectroscopy and angle-resolved photoemission spectroscopy experiments that the recently discovered 'two-dimensional (2D) superconductor' of single-layer FeSe also exhibits 1D topological edge states within an energy gap of ∼40 meV at the M point below the Fermi level. It is the first 2D material that supports both superconducting and topological states, offering an exciting opportunity to study 2D topological superconductors through the proximity effect.

Abstract
Bretschneidera sinensis is an endangered species that is mainly distributed in South China. As a tertiary relict and the single species in the Bretschneideraceae family, it has a high conservation value. To investigate the influence of human disturbance on its mating system, 63 new microsatellites were developed using restriction-site-associated DNA sequencing and their polymorphisms were tested on 30 samples from one population. Among the 63 microsatellites, the number of alleles per locus ranged from 2 to 16. The observed and expected heterozygosities ranged from 0.133 to 0.967 and from 0.127 to 0.912, respectively. These microsatellites may be used for studying the mating system of B. sinensis as well as the within-population hereditary structure.

Abstract
OBJECTIVE To explore the association and gene-environment interaction between single nucleotide polymorphisms (SNPs) involved in cell-cell adhesion and non-syndromic cleft lip with or without cleft palate (NSCL/P) among Chinese population. METHODS A total of 806 NSCL/P trios were drawn by an international consortium, which conducted a genome-wide association study (GWAS) using a case-parent trio design to investigate genes affecting risks to NSCL/P. The transmission disequilibrium test (TDT) was used to explore the association between cell-cell adhesion genes, including CDH1, CTNNB1, PVRL1, PVRL2, PVRL3, ACTN1, VCL, LEF1, and NSCL/P. Conditional Logistic regression models were used to estimate effects on risk of exposed and unexposed children. Four common maternal exposures including maternal smoking, environmental tobacco smoke, alcohol consumption and multivitamin supplementation during pregnancy were included in this study. RESULTS A total of 226 SNP markers were tested after quality control in this study. Although 23 SNPs in three genes (CTNNB1, CDH1, ACTN1) showed nominal significant association with NSCL/P in the TDT (P<0.05).There were no significant evidence of linkage and association that remained in the transmission disequilibrium test after Bonferroni correction(P>0.000 2). Tests for gene-environment interaction yielded significant results between rs743127 in ACTN1 and environmental tobacco smoke (P=0.000 1) with an estimated OR (case|G and E)=2.00(95%CI: 1.23-3.26) and OR (case|G no E)=0.59 (95%CI: 0.38-0.90). Among the lower P value results in gene-environment tests, there were no significant results between rs1475034, rs370535, rs2273419 in ACTN1, rs106871 in CTNNB1 and environmental tobacco smoke interaction. There were also no significant results between rs7634000, rs2971366, rs2634553, rs1489032, rs7624812 in PVRL3 and multivitamin supplementation during pregnancy in gene-environment tests(P>0.000 2). CONCLUSION There is no association between cell-cell adhesion genes, including CDH1, CTNNB1, PVRL1, PVRL2, PVRL3, ACTN1, VCL, LEF1, and NSCL/P when the genes are considered alone. But our results suggest that SNPs in ACTN1 may influence the risk to NSCL/P through gene-environment interaction.
