Abstract
BACKGROUNDS AND AIMS This study aims to explore the efficacy of reperfusion strategies on the clinical outcomes of ST-elevation myocardial infarction (STEMI) patients over 80 years old in China. METHODS A retrospective cohort study was performed on STEMI patients over 80 years old who underwent reperfusion strategies and no reperfusion between January 2014 and December 2021 based on the China Cardiovascular Association (CCA) Database-Chest Pain Center. RESULTS This study included a total of 42,699 patients (mean age 84.1 ± 3.6 years, 52.2% male) among which 19,280 (45.2%) underwent no reperfusion, 20,924 (49.0%) underwent primary percutaneous coronary intervention (PCI), and 2,495 (5.8%) underwent thrombolytic therapy. After adjusting for potential confounders, multivariable logistic regression analysis revealed that patients who underwent primary PCI strategy showed a significantly lower risk of in-hospital mortality (OR = 0.62, 95% CI: 0.57-0.67, P < 0.001) and the composite outcome (OR = 0.83, 95% CI: 0.79-0.87, P < 0.001) compared to those received no reperfusion. In contrast, patients with thrombolytic therapy exhibited a non-significantly higher risk of in-hospital mortality (OR = 0.99, 95% CI: 0.86-1.14, P = 0.890), and a significantly elevated risk of the composite outcome (OR = 1.15, 95% CI: 1.05-1.27, P = 0.004). During a median follow-up of 6.7 months post-hospital admission, there was a percentage 31.4% of patients died and patients in the primary PCI group consistently demonstrated a reduced incidence of all-cause mortality (HR = 0.58, 95% CI: 0.56-0.61, P < 0.001). CONCLUSION STEMI patients over 80 years old who underwent the primary PCI strategy are more likely to have favorable clinical outcomes compared to those who received no reperfusion, whereas, thrombolytic therapy warrants careful assessment and monitoring.

Abstract
Background Microvascular dysfunction in patients with non-obstructive epicardial coronary may aggravate patient's symptoms or lead to various clinical events. Objective To investigate the correlation between dynamic single photon emission computed tomography (D-SPECT) derived coronary flow reserve (CFR) and TIMI frame count (TFC) in patients with non-obstructive epicardial coronary patients. Methods Patients with suspected or known stable CAD who were recommended to undergo invasive coronary angiography were prospectively enrolled in this study. Those who had non-obstructive coronary received TIMI frame count (TFC) and D-SPECT. A cut-off value of >40 was defined as slow flow referred to TFC. Results A total of 47 patients diagnosed with non-obstructive coronary were enrolled. The mean age of patients was 66.09 ± 8.36 years, and 46.8% were male. Dynamic SPECT derived coronary flow reserve (CFR) was significantly correlated with TIMI frame count in 3 epicardial coronary (LAD: r=-0.506, P = 0.0003; LCX: r= -0.532, P = 0.0001; RCA: r= -0.657, P < 0.0001). The sensitivity and specificity of CFR in identifying abnormal TIMI frame count < 40 was 100.0% and 57.6% in LAD, 62.5% and 87.0% in LCX, 83.9% and 75.0% in RCA, respectively. The optimal CFR cut-off values were 2.02, 2.47, and 1.96 among the three vessels. Conclusion In patients with non-obstructive coronary, CFR derived from D-SPECT was strongly correlated with TFC. This study demonstrates that that CFR may be an alternative non-invasive method for identifying slow flow in non-obstructive coronary.

Abstract
PURPOSE/OBJECTIVE(S) Consolidation immunotherapy after chemoradiotherapy (CRT) is the standard of care for unresectable stage III non-small cell lung cancer (NSCLC). However, whether upfront immunotherapy before CRT has similar benefits has not been addressed. This study aimed at exploring the efficacy and safety of induction immunotherapy for unresectable stage III NSCLC through real-world data. MATERIALS/METHODS Patients diagnosed with stage III NSCLC who received immunotherapy in combination with sequential (sCRT) or concurrent CRT (cCRT) between November 2018 and December 2021 were retrospectively identified. Patients were divided into induction (Ind), consolidation (Con) and induction plus consolidation (Ind+Con) immunotherapy groups. Progression-free survival (PFS) and overall survival (OS) were assessed from the initiation of treatment and estimated by Kaplan‒Meier method. The potential factors affecting PFS and OS were analyzed by univariate and multivariate Cox regression models. RESULTS One hundred and two patients were included, with 52 (51.0%) patients in the Ind group, 35 (34.3%) in the Con group and 15 (14.7%) in the Ind+Con group. Median PFS was 24.0 months vs. 36.0 months vs. 19.0 months in the three groups, and 2-year PFS were 43.0% vs 51.1% vs 44.4% (p = 0.940). Median OS was not reached (NR) vs. 44.0 months vs. NR, with a 2-year OS rate of 80.5% vs. 84.4% vs. 86.2% (p = 0.861). In the cCRT setting, 2-year PFS rates were 56.7% vs. 71.6% vs. 100.0% (p = 0.439), 2-year OS rates were 92.3% vs. 89.3% vs. 100.0% in the three groups (p = 0.827). In multivariate analysis, elder (HR = 0.487, p = 0.037) and cCRT (HR = 0.282, p = 0.001) were the independent factors favoring PFS, while only elder (HR = 0.088, p = 0.021) was the independent factors favoring OS. Adverse events were similar in the three arms. Further analysis found the objective response rate (ORR) and disease control rate (DCR) in the Ind and Ind+Con group after induction immunotherapy were 59.7% and 98.5%, respectively. Only 1 (1.5%) patient developed progression. Subgroup analysis showed no significant difference in PFS (p = 0.520) and OS (p = 0.116) between patients who responded to induction immunotherapy (PR+CR) and those who did not (SD+PD). Patients with <4 cycles of induction immunotherapy exhibited numerically better PFS than those with ≥4 cycles of induction immunotherapy (p = 0.113) and improved OS (p = 0.021). CONCLUSION Induction immunotherapy may achieve similar survival benefits to consolidation immunotherapy, and the combination of induction and consolidation immunotherapy with cCRT appears to achieve better outcomes. It seems feasible and safe to upfront immunotherapy before CRT, and further investigations on the combination of induction immunotherapy and CRT are warranted.

Abstract
OBJECTIVE To investigate the correlation of stress-inducible phosphoprotein 1 (STIP1) expression level with prognosis of different cancers and its potential role in immunotherapy. METHODS TCGA, TARGET and GTEx databases were used for bioinformatic analysis of STIP1 expression level and its prognostic value in different cancers. We also detected STIP1 expression immunohistochemically in 10 pairs of colorectal cancer and adjacent tissues. We further analyzed the correlation of STIP1 expression level with tumor mutational burden, microsatellite instability, immune cell infiltration, immune regulators and outcomes of different cancers. STIP1- related proteins were identified using protein- protein interaction (PPI) network analysis, and functional enrichment analysis was performed to analyze the regulatory pathways involving STIP1. RESULTS Bioinformatics analysis showed that STIP1 was highly expressed in most tumors compared with the normal tissues (P < 0.05), which was confirmed by immunohistochemistry of the 10 pairs of colorectal cancer tissues. STIP1 expression level was correlated with clinical stages of multiple cancers (P < 0.05), and in some cancer types, an upregulated STIP1 expression was correlated with a poor prognosis of the patients in terms of overall survival, disease-specific survival, disease-free survival and progression-free survival (P < 0.05). STIP1 expression was significantly correlated with tumor mutational burden, microsatellite instability, immune cell infiltration and immunomodulatory factors in most tumors (P < 0.05). PPI network analysis indicated that STIP1-related proteins included HSPA4, HSPA8, and HSP90AA1. KEGG enrichment analysis suggested that the high expression of STIP1 in liver cancer was related mainly with valerate metabolism, tryptophan metabolism, and butyrate metabolism pathways; HALLMARK enrichment analysis suggested high STIP1 expression in liver cancer was involved in bile acid and fatty acid metabolism. CONCLUSION STIP1 is up-regulated in multiple cancer types and its expression level is correlated with clinical tumor stage, tumor mutational burden, microsatellite instability, immune cell infiltration and immunomodulatory factors.

Abstract
Objective: To compare the efficacy and safety of short-course radiotherapy with total neoadjuvant therapy (SCRT-TNT) and neoadjuvant chemoradiotherapy (nCRT) in patients with locally advanced middle and low rectal cancer. Methods: A retrospective cohort study was carried out. A of 126 patients with locally advanced middle and low rectal cancer who were treated in the Department of Gastrointestinal Cancer Surgery of Fujian Cancer Hospital from September 2016 to March 2020 were enrolled, including 73 males and 53 females, with a mean age of (56.5±9.8) (23-77) years. Based on neoadjuvant regimen (nCRT treatment was performed before December 2018 and SCRT-TNT treatment was carried out after January 2019), patients were divided into nCRT group (n=68) and SCRT-TNT group (n=58). There were no statistically significant differences in age, sex, distance from tumor to anal verge, Eastern Cooperative Oncology Group (ECOG) performance status and clinical TNM stage between the two groups (all P>0.05). Patients in both groups received pelvic intensity-modulated radiotherapy (IMRT). The radiotherapy dose of nCRT group was 50Gy/25 times/5 weeks. Patients in nCRT group received oral capecitabine chemotherapy during radiotherapy and underwent surgery 6-8 weeks after chemoradiation. However, patients in SCRT-TNT group received CapeOX regimen (oxaliplatin+capecitabine) for 2 cycles of induction chemotherapy, followed by short-course radiotherapy (25Gy/5 times/5 days), then underwent a radical surgery two weeks after completion of consolidation chemotherapy (4 cycles). The adverse reactions, perioperative safety and efficacy of neoadjuvant therapy were compared and analyzed between the two groups. Results: Both groups completed neoadjuvant therapy as planned. Patients in nCRT group and SCRT-TNT group had similar incidence of adverse reactions to radiotherapy and chemotherapy, however, there were no statistically significant differences in the incidence of surgical complications, operation time, intraoperative blood loss and postoperative length of hospital stay (all P>0.05). A total of 119 patients underwent total mesenterectomy (TME), including 64 patients in the nCRT group and 55 patients in the SCRT-TNT group, all with R0 resection. The pathological complete response (pCR) rate was 10.9% (7/64) in the nCRT group and 25.5% (14/55) in the SCRT-TNT group, respectively, with a statistically significant difference (P=0.038). Two years after surgery, there was no statistically significant difference in local recurrence rate and overall survival rate between the two groups (both P>0.05). However, the clinical metastasis rate of SCRT-TNT group was significantly lower than that of nCRT group (20.3% vs 9.1%), with a statistically significant difference (P<0. 05). Conclusion: SCRT-TNT do not increase the adverse reactions of radio chemotherapy and perioperative risks in the treatment of locally advanced middle and low rectal cancer, and the tumor regression effect is good, which is worthy of clinical promotion.

Abstract
Background Coronary physiology measurement in serial coronary lesions with multiple stenoses is challenging. Therefore, we evaluated the feasibility of Murray fractal law‐based quantitative flow ratio (μQFR) virtual stenting for guidance of serial coronary lesions intervention. Methods and Results Patients who underwent elective coronary angiography and had 2 serial de novo coronary lesions of 30% to 90% diameter stenosis by visual estimation were prospectively enrolled. μQFR and fractional flow reserve (FFR) were assessed after coronary angiography. In vessels with an FFR ≤0.80, the lesion with the larger pressure gradient was considered to be the primary lesion and treated firstly, followed by FFR measurement. The second lesion was stented when FFR ≤0.80. All μQFR and predicted μQFR after stenting were calculated from diagnostic coronary angiography before interventions, with the analysts masked to the FFR data. A total of 54 patients with 61 target vessels were interrogated. Percutaneous coronary intervention was performed in 44 vessels with FFR ≤0.80. After stenting the primary lesions, 14 nonprimary lesions had FFR ≤0.80 and a second drug‐eluting stent was implanted. There was excellent correlation (r=0.97, P<0.001) and good agreement (mean difference: 0.00±0.03) between baseline μQFR and FFR in identifying flow‐limiting lesions. Per‐vessel diagnostic accuracy of μQFR on de novo lesions was 96.7% (95% CI, 88.7%–99.6%). μQFR and FFR are highly consistent (93.2%) in identifying the primary lesion requiring revascularization. After stenting the primary lesions, per‐vessel diagnostic accuracy of predicted μQFR for identifying the significance of the nonprimary lesion was 90.9%. Predicted residual μQFR with virtual stenting was higher than final FFR (mean difference: 0.05±0.06). Conclusions In vessels with serial coronary lesions, virtual stenting by μQFR can identify the primary flow‐limiting lesion for revascularization.

Abstract
Objective: To explore the surgical strategy of nipple areola complex (NAC) management in central breast cancer. Methods: A retrospective analysis was conducted on 164 cases of central breast cancer who underwent surgery treatment from December 2017 to December 2020 in the Breast Center of Beijing Tongren Hospital, Capital Medical University. Prior to the surgery, the tumor-nipple distance (TND) and the maximum diameter of the tumor were measured by magnetic resonance imaging (MRI). The presence of nipple invagination, nipple discharge, and nipple ulceration (including nipple Paget's disease) were recorded accordingly. NAC was preserved in patients with TND≥0.5 cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative intraoperative frozen pathological margin. All patients with signs of NAC involvement, TND<0.5 cm or positive NAC basal resection margin confirmed by intraoperative frozen pathology underwent NAC removal. χ(2) test or Fisher exact test was used to analyze the influencing factors. Results: Of the 164 cases of central breast cancer, 73 cases underwent breast-conserving surgery, 43 cases underwent nipple-areola complex sparing mastectomy (NSM), 34 cases underwent total mastectomy, and the remaining 14 cases underwent skin sparing mastectomy (SSM). Among the 58 cases of NAC resection (including 34 cases of total mastectomy, 14 cases of SSM, and 10 cases of breast-conserving surgery), 25 cases were confirmed tumor involving NAC (total mastectomy in 12 cases, SSM in 9 cases, and breast-conserving surgery in 4 cases). The related factors of NAC involvement included TND (P=0.040) and nipple invagination (P=0.031). There were no correlations between tumor size (P=0.519), lymph node metastasis (P=0.847), bloody nipple discharge (P=0.742) and NAC involvement. During the follow-up period of 12 to 48 months, there was 1 case of local recurrence and 3 cases of distant metastasis. Conclusions: For central breast cancer, data suggest that patients with TND≥0.5cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative NAC margin in intraoperative frozen pathology should be treated with NAC preservation surgery, whereas for those with TND<0.5 cm or accompanied by signs of NAC invasion, NAC should be removed. In addition, nipple reconstruction can be selected to further improve the postoperative appearance of patients with central breast cancer.

Abstract
INTRODUCTION Coronary CT angiography (CCTA)-derived quantitative flow ratio (CT-QFR) is a novel non-invasive technology to assess the physiological significance of coronary stenoses, which enables fast and on-site computation of fractional flow reserve (FFR) from CCTA images. The objective of this investigator-initiated, prospective, single-centre clinical trial is to evaluate the diagnostic performance of CT-QFR with respect to angiography-derived QFR, using FFR as the reference standard. METHODS AND ANALYSIS A total of 216 patients who have at least one lesion with a diameter stenosis of 30%-90% in an artery with ≥2.0 mm reference diameter will be enrolled in the study. FFR will be measured during invasive coronary angiography. CT-QFR and QFR will be assessed in two independent core laboratories in a blinded fashion. The primary endpoint is the diagnostic accuracy of CT-QFR in identifying haemodynamically significant coronary stenosis with FFR as the reference standard. The major secondary endpoint is the non-inferiority of CT-QFR compared with QFR in the patients without extensively calcified lesions. ETHICS AND DISSEMINATION The study was approved by the Ethics Committee of Huadong Hospital Affiliated to Fudan University (2020K192). Outcomes will be disseminated through publications in peer-reviewed journals and presentations at scientific conferences. TRIAL REGISTRATION NUMBER NCT04665817.

Abstract
Background No validated biomarkers currently exist for predicting the efficacy outcomes in patients with neuroendocrine tumors (NETs) treated with antiangiogenic therapy. We aimed to evaluate the association between treatment-related adverse events (TRAEs) and efficacy outcomes of surufatinib in patients with advanced NET. Patients and methods We included patients with NET treated with surufatinib in two multicenter, randomized, double-blind, placebo-controlled, phase III trials (SANET-p and SANET-ep) in this study. The main exposure was the presence of any of the TRAEs including hypertension, proteinuria, and hemorrhage in the first 4 weeks of surufatinib treatment. The primary outcome of the study was investigator-assessed progression-free survival (PFS). PFS outcomes were estimated using the Kaplan–Meier method with the log-rank test. Hazard ratios (HRs) were calculated by using univariable and multivariable Cox proportional hazard regression models. Blinded independent image review committee (BIIRC) assessments and 4-week landmark analysis were also performed as supportive evaluations. Results During the study period, a total of 242 patients treated with surufatinib were included in the analysis, and 164 (68%) patients had at least one of hypertension, proteinuria, and hemorrhage in the first 4 weeks of treatment. The presence of TRAEs in the first 4 weeks was associated with prolonged median PFS [11.1 versus 9.2 months; HR 0.67, 95% confidence interval (CI) 0.47-0.97; P = 0.036]. In multivariable Cox regression analysis, the presence of TRAEs was also significantly associated with longer PFS (HR 0.65, 95% CI 0.44-0.97; P = 0.035). Similar results were obtained in the BIIRC assessments and 4-week landmark analysis. Conclusions Treatment-related hypertension, proteinuria, and hemorrhage could be potential biomarkers to predict antitumor efficacy of surufatinib in patients with advanced NET. Future prospective studies are needed to validate the findings. Trial registration ClinicalTrials.govNCT02589821; https://clinicaltrials.gov/ct2/show/NCT02589821 and ClinicalTrials.gov NCT02588170; https://clinicaltrials.gov/ct2/show/NCT02588170 Treatment-related hypertension, proteinuria, or hemorrhage is associated with longer survival in NETs. The association is confirmed by the BIIRC assessments and 4-week landmark analysis. TRAEs can be biomarkers to predict antitumor efficacy in patients with NET.

Abstract
Objective: To examine the outcome of different incision selection for nipple-sparing mastectomy (NSM) with implant-based breast reconstruction (IBBR). Methods: Ninety-Two cases accepted NSM and IBBR from totally 1 002 cases of breast cancer admitted to Beijing Tongren Hospital Affiliated to Capital Medical University from June 2013 to December 2020 were analyzed retrospectively. All the patients were female, aging (42.0±7.5) years (range: 27 to 64 years). There were 12 patients at stage 0, 47 patients at stage Ⅰ, 17 patients at stage Ⅱ, and 16 patients at stage Ⅲ. The patients were divided in three groups by the incision: peri-areolar group (n=23), inframammary group (n=33) and lateral group (n=36). The age, tumor size, lymph node status, hormone receptor, operation method and postoperative complications were followed-up of three groups and compared by one-way ANOVA, χ2 test or Fisher's exact test and expansion to comparied. Results: There was no significant difference in operation time ((180.7±54.0) minutes vs. (176.9±48.1) minutes vs. (194.6±37.5) minutes, F=1.401, P=0.252), postoperative drainage volume ((497.5±226.0) ml vs. (495.4±182.5) ml vs. (519.8±172.0) ml, F=0.167, P=0.846) and drainage time ((8.8±3.8) days vs. (8.0±2.5) days vs. (8.3±2.9) days, F=0.542, P=0.583) among the peri-areolar, inframammary, and lateral groups. The cumulative postoperative complications were relatively higher in the peri-areola group (26.1%(6/23) vs. 0 vs.8.3%(3/36), χ²=9.675, P=0.004). All female patients were followed up for (49.0±25.6) months(range: 12 to 112 months). Breast cancer related death rate was 2.2% (2/92), local recurrence was 1.1% (1/92), regional recurrence was 4.3% (4/92), distant metastasis was 6.5% (6/92), and the disease-free survival rate was 88.0% (81/92). Conclusion: The surgical effects of the peri-areolar, inframammary and lateral incisions for NSM and IBBR are approximate, the total complication rate of the peri-areolar incision is slightly higher.

Abstract
Background:Paraoxonase-1 (PON1) is a high-density lipoprotein (HDL)-associated enzyme with paraoxonase, lactonase and arylesterase activities.1 PON1 contributes to the antioxidant properties of HDL, and is being investigated for its atheroprotective properties.1 Patients (pts) with rheumatoid arthritis (RA) who are homozygous for the RR genotype of the Q192R gene polymorphism on PON1 (rs662) have increased paraoxonase activity, and lower risk of carotid plaques, vs those with QQ or QR genotypes.2 Tofacitinib is an oral Janus kinase inhibitor for the treatment of RA.Objectives:To investigate the relationship between PON1 genotype/activity and risk of major adverse cardiovascular events (MACE) in the tofacitinib RA clinical programme.Methods:In this post hoc analysis, data were pooled from pts enrolled in nine Phase 2/3 studies of tofacitinib in RA. Enzyme activities in pt plasma samples were measured at individual study baseline (BL) and at follow-up visits using three substrates: paraoxon (paraoxonase activity), dihydrocoumarin (lactonase activity) and phenylacetate (arylesterase activity). The effect of the PON1 Q192R genotype (QQ, QR or RR) on BL paraoxonase/lactonase/arylesterase activity was assessed using linear regression for each study, with age and sex as covariates, and then fixed-effect meta-analysis assessed effects across studies. The risk of MACE by enzyme activity was determined using Cox proportional hazards regression stratified by clinical studies. Univariate regression against BL enzyme activity and other risk factors, as well as both minimally and fully adjusted multivariable regressions against time-varying enzyme activity, are presented.Results:The analysis included 1969 pts with RA who received ≥1 dose of tofacitinib and had PON1 activity measures available at BL; 39 pts had ≥1 MACE event. Compared with the QQ genotype, the RR genotype had a highly significant positive association with BL paraoxonase activity, and a highly significant negative association with BL lactonase and arylesterase activity (Table 1). A univariate analysis identified several BL covariates significantly associated with risk of MACE (Figure 1a). Time-varying models found a highly significant association of increased paraoxonase activity over time with lower risk of future MACE, even after controlling for low-density lipoprotein or HDL cholesterol levels, and other traditional cardiovascular (CV) risk factors identified in univariate analysis (Figure 1b), with similar findings for lactonase and arylesterase (data not shown).Table 1.Effect of PON1 genotype (RR vs QQ) on BL enzyme activitynEstimate95% CIp valueCochran’s Q testParaoxonase12291.0350.93, 1.141<0.00010.209Lactonase1188-0.375-0.505, -0.246<0.00010.025Arylesterase1231-1.016-1.382, -0.649<0.00010.251Fixed-effects model; estimate >0 favours RR genotype and <0 favours QQ genotypeBL, baseline; CI, confidence intervalConclusion:Higher activity of the HDL-associated protein PON1 over time was associated with a significantly reduced risk of future MACE in pts with RA receiving tofacitinib, after controlling for traditional CV risk factors and cholesterol levels.

Abstract
Objective: To investigate the efficacy and safety of emergency venous sinus stenting in the treatment of acute visual impairment caused by idiopathic intracranial hypertension (IIH). Methods: A descriptive cross-sectional study design was used to retrospectively analyze 38 patients undergoing venous sinus stenting in the First Affiliated Hospital of Zhengzhou University from January 2013 to October 2019. A total of 9 patients who had sudden short-term vision loss met the inclusion criteria. Routine visual field and fundus examination were performed. The venous sinus stenosis (CVSS) was confirmed by MR venography or DSA. The pressure gradient at both ends of CVSS was ≥10 mmHg(1 mmHg=0.133 kPa). All patients were treated with emergency venous sinus stenting. Six-month follow-up data were collected for comparison, evaluation of the therapeutic effect, and observation of adverse reactions. Results: All 9 patients were successfully treated with venous sinus stent. The pressure gradient at the distal and proximal ends of the stenosis after stent implantation decreased to (2.3±1.2) mmHg. After 6 months of follow-up, the papilledema was significantly improved or disappeared in all patients. The average grade of papilledema decreased from 2.44±0.73 before operation to 0.56±0.53 after treatment (t=6.314, P<0.001). The visual acuity of 9 patients recovered to the pre-onset level or improved significantly after 6 months. The average baseline value of preoperative visual acuity (logMAR) was 0.12±0.11, which increased to 0.74±0.13 on average 6 months after operation (t=-10.827, P<0.001). No recurrence of symptoms or serious adverse reactions occurred in all patients during the follow-up period. Conclusion: For patients with acute visual impairment caused by idiopathic cranial hypertension, emergency venous sinus stenting is a relatively safe and effective treatment that can effectively improve visual acuity.

Abstract
Tooth eruption is a complex process requiring precise interaction between teeth and adjacent tissues. Molecular analysis demonstrates that bone remodeling plays an essential role during eruption, suggesting that a parathyroid hormone 1 receptor (PTH1R) gene mutation is associated with disturbances in bone remodeling and results in primary failure of eruption (PFE). Recent research reveals the function of PTH1R signaling in mesenchymal progenitors, whereas the function of PTH1R in mesenchymal stem cells during tooth eruption remains incompletely understood. We investigated the specific role of PTH1R in Prx1+ progenitor expression during eruption. We found that Prx1+-progenitors occur in mesenchymal stem cells residing in alveolar bone marrow surrounding incisors, at the base of molars and in the dental follicle and pulp of incisors. Mice with conditional deletion of PTH1R using the Prx1 promoter exhibited arrested mandibular incisor eruption and delayed molar eruption. Micro-computed tomography, histomorphometry, and molecular analyses revealed that mutant mice had significantly reduced alveolar bone formation concomitant with downregulated gene expression of key regulators of osteogenesis in PTH1R-deficient cells. Moreover, culturing orofacial bone-marrow-derived mesenchymal stem cells (OMSCs) from Prx1Cre;PTH1Rfl/fl mice or from transfecting Cre recombinase adenovirus in OMSCs from PTH1Rfl/fl mice suggested that lack of Pth1r expression inhibited osteogenic differentiation in vitro. However, bone resorption was not affected by PTH1R ablation, indicating the observed reduced alveolar bone volume was mainly due to impaired bone formation. Furthermore, we found irregular periodontal ligaments and reduced Periostin expression in mutant incisors, implying loss of PTH1R results in aberrant differentiation of periodontal ligament cells. Collectively, these data suggest that PTH1R signaling in Prx1+ progenitors plays a critical role in alveolar bone formation and periodontal ligament development during eruption. These findings have implications for our understanding of the physiologic and pathologic function of PTH1R signaling in tooth eruption and the progression of PFE.

Abstract
Trigeminal neuralgia is one of the most common of the neuropathic pains, and it can seriously influence patients' quality of life. Calcitonin gene-related peptide (CGRP) is a type of nociceptive neurotransmitter that is expressed in neurons of the trigeminal ganglion and plays a major part in transmitting pain. The rat model of trigeminal neuralgia was established by causing a chronic constriction injury of the infraorbital nerve (CCI-ION). Male Sprague-Dawley rats (n=24) were randomly divided into a sham control group (sham, n=6), sham-treated with palmatine group (sham+palmatine, n=6), trigeminal nerve model group (TN, n=6), and trigeminal nerve treated with palmatine group (TN+palmatine, n=6). Fifteen days after the operation the mechanical response threshold was decreased in the TN group compared with the sham group. From postoperative day 7 to day 15, the mechanical response threshold in the TN+palmatine group significantly increased compared with the TN group. On postoperative day 15 the results of quantitative polymerase chain reaction (qPCR), immunohistochemical staining, and western blotting showed an obvious increase in expression of CGRP and its receptors, serum concentrations of interleukin-1β (IL-1β), and tumour necrosis factor-α (TNF-α), and phosphorylation of protein kinase C (PKC) in the trigeminal ganglia of the TN group compared with the sham group, but these increases could be down-regulated by treatment with palmatine. Palmatine might therefore have therapeutic potential for the treatment of trigeminal neuralgia by inhibiting the expression of CGRP and its receptors in trigeminal ganglia, suppressing the serum concentrations of IL-1β and TNF-α, and decreasing the phosphorylation of PKC in the trigeminal ganglia of affected rats.

Abstract
Objective: To summarize the status of immediate breast reconstruction (IBR) after mastectomy in Beijing City, Tianjin City and Hebei Province. Methods: A retrospective analysis was made on the data of 382 cases with breast cancer who were treated and followed up successfully with immediate breast reconstruction after mastectomy from January 2012 to December 2016 in Beijing City, Tianjin City and Hebei Province. Clinic data of the followed-up 382 cases (all female, age (38.5±4.2) years (range: 24 to 70 years)), including general information, tumor information, sugery methods, and treatments after surgery were collected. The survival status, metastasis,complications and prognosis were followed up. Cosmetic effcet was evalated by Harris method, and life quality by Functional Assessment of Cancer Therapy-Breast scale (FACT-B). χ(2) test was used to compare the difference between year 2012 and year 2013 to 2016. Bonferroni method was used to correct the inspection level, which was 0.05/10=0.005. The trend of IBR rate (ratio of IBR to modified radical mastectomy) from 2013 to 2016 was analyzed by trend χ(2) test. Results: There was 46 cases in stage 0, 152 cases in stage Ⅰ, 165 cases in stage Ⅱ, 19 cases in stage Ⅲ. Twenty-five cases was treated by neoadjuvant chemotherapy, 231 by chemotherapy and 35 by radiotherapy. The proportion of implant reconstruction was 48.7% (186/382), more than expanded of 21.5% (82/382), with latissimus dorsi of 12.0% (46/382), TRAM of 8.9% (34/382), DIEP of 2.1% (8/382), and latissimus plus implant of 6.8% (26/382). According to the Harris standard, the excellent and good rate of the cosmetic effect of the reconstructed breast was 93.7%. The score of FACT-B was 108.20±16.9 (range: 67 to 144) 1 year postoperatively. Compared with 2012, the IBR rate was significant increased, till 2015, the IBR rate was 153/10 000 cases (χ(2)=47.028, P=0.000). Conclusions: There is a significant increase on IBR rate in Beijing City, Tianjin City and Hebei province by year. Most of cases received IBR is stage Ⅰ to Ⅱ. Implant reconstruction is the main reconstructive method. Postoperative cosmetic effects and quality of life are both meet patients' demon.

Abstract
Acute myocardial infarction is one of the leading causes of deaths worldwide. Although ameliorative therapies against ischemic injury have remarkably reduced death rates among patients, they are inevitably complicated by reperfusion injury. Therefore, it is essential to explore other approaches to reduce ischemia/reperfusion injury (IRI). Modulating the levels of nicotinamide adenine dinucleotide (NAD+) is a promising therapeutic strategy against some aging-related diseases. The aim of this study was to determine the role of NAD+ in a swine model of myocardial IRI. Fourteen Bama miniature pigs were subjected to 90 min transluminal balloon occlusion, and then randomly administrated with 20 mg/kg NAD+ or saline before reperfusion. Emission computerized tomography (ECT) was performed immediately and 4 weeks after reperfusion, and the cardiac tissues were analyzed histologically. In addition, the levels of cardiac function markers and the pro-inflammatory cytokines IL-1β and TNF-α were also measured. NAD+ administration markedly reduced myocardial necrosis, enhanced glucose metabolism, and promoted cardiac function recovery. The extent of inflammation was also reduced in the NAD+ treated animals, and corresponded to less cardiac fibrosis and better ventricular compliance. Thus, NAD+ supplementation protected the myocardium from IRI, making it a promising therapeutic agent against acute myocardial ischemic disease.

Abstract
Many robotic platforms can indeed reduce radiation exposure to clinicians during percutaneous coronary intervention (PCI), however, interventionalists' natural manipulations are rarely involved in robot-assisted PCI. This requires more attention to analyze interventionalists' natural behaviors during conventional PCI. In this study, four types of natural behavior (i.e., muscle activity, hand motion, proximal force, and finger motion) were synchronously acquired from ten subjects while performing six typical types of guidewire manipulation. These behaviors are evaluated by a hidden Markov model (HMM) based analysis framework for relevant behavior selection. Relevant behaviors are further used as the input of two HMM-based classification frameworks to recognize guidewire motion patterns. Experimental results show that under the basic classification framework (BCF), 91.01% and 93.32% recognition accuracies can be achieved by using all behaviors and relevant behaviors, respectively. Furthermore, the hierarchical classification framework can significantly enhance the recognition ability of relevant behaviors with an accuracy of 96.39%. These promising results demonstrate great potential of proposed methods for promoting the future design of human-robot interfaces in robot-assisted PCI.

Abstract
Implantable neural probes that are mechanically compliant with brain tissue offer important opportunities for stable neural interfaces in both basic neuroscience and clinical applications. Here, we developed a Neurotassel consisting of an array of flexible and high-aspect ratio microelectrode filaments. A Neurotassel can spontaneously assemble into a thin and implantable fiber through elastocapillary interactions when withdrawn from a molten, tissue-dissolvable polymer. Chronically implanted Neurotassels elicited minimal neuronal cell loss in the brain and enabled stable activity recordings of the same population of neurons in mice learning to perform a task. Moreover, Neurotassels can be readily scaled up to 1024 microelectrode filaments, each with a neurite-scale cross-sectional footprint of 3 × 1.5 μm2, to form implantable fibers with a total diameter of ~100 μm. With their ultrasmall sizes, high flexibility, and scalability, Neurotassels offer a new approach for stable neural activity recording and neuroprosthetics.

Abstract
OBJECTIVE To prove the effectiveness and safety of multi-electrode ablation catheter in renal denervation (RDN) by optical coherence tomography (OCT). METHODS Sixteen renal arteries were enrolled from 8 pigs. Angiography and OCT were performed to analyze the morphological changes before RDN and at 1-month follow-up. Blood pressure and creatinine were measured to prove the effectiveness and safety of the catheter. RESULTS One renal artery was excluded because of the small diameter. Fifteen renal arteries successfully underwent renal denervation and OCT. Mean blood pressure was significantly reduced at 1 month after RDN (122.40 ± 3.54 mmHg vs. 106.50 ± 2.06 mmHg, n = 8, P < .001). Creatinine follow-up after 1 month showed no significant change (45.37 ± 7.44 vs. 65.87 ± 49.20 μmol/L, n = 8, P = 0.275). The minimal lumen diameter showed that the renal artery immediately narrowed after the procedure (7.17 ± 0.60 mm vs. 5.93 ± 0.97 mm, n = 15, P < .001). Vasospasm, vascular wall edemas, and thrombus formations all showed significant changes after the procedure except renal artery dissection (0% vs. 21.4%, P = 0.067) under the OCT. Adverse event as renal artery occluded showed no significant difference (0% vs. 6.7%, P > .05). OCT results showed no significant difference in vasospasm, dissections, wall edemas, and thrombus formations (P > .05) at 1 month after the procedure. CONCLUSION This multi-electrode ablation catheter could cause minor injury to renal artery instantly after RDN, but it is found to be safe in the animal model at 1-month follow-up.

Abstract
This study was designed to explore the effects of long-term renal denervation (RDN) on blood pressure and renal function in spontaneously hypertensive rats (SHR). RDN was performed in bilateral renal arteries with 10% phenol in absolute ethanol in SHR and Wistar-Kyoto rats (WKY) at 13 weeks. Age-matched SHR and WKY served as controls. Blood pressure was measured. Plasma, urine and kidneys were collected 8 months after the RDN operation. Plasma renin activity (PRA), aldosterone levels, reactive oxidative stress, renal function and structural remodeling were assessed. RDN-treated SHR demonstrated a lower spontaneous rise in systolic blood pressure than rats in the SHR-Sham group (P < 0.01, at 20, 27, 34 and 41 weeks), except at 48 weeks (198.2 ± 12.9 vs 209.4 ± 11.9 mmHg, P = 0.145). WKY were not affected by RDN. Renal tissue norepinephrine was decreased by RDN in both SHR and WKY. Plasma PRA activity, aldosterone levels, and NAD(P)H oxidase activity were reduced by the RDN in SHR. Plasma eNOS and NO were increased by RDN only in SHR. The renal nerve was destroyed by RDN with no regeneration after 8 months. The progression of renal dysfunction associated with urinary protein excretion, glomerular sclerosis, and tubulointerstitial fibrosis was attenuated by RDN only in SHR through downregulation of the ACE/Ang II/AT1R axis and upregulation of the ACE2/Ang-(1-7)/MasR axis in the kidney. Thus, RDN delays the onset of hypertension and ameliorates glomerular sclerosis and tubulointerstitial fibrosis in SHR.

Abstract
Cardiovascular disease is a leading cause of death worldwide, requiring the development of new therapeutic strategies including stem cell therapy. Pentraxins (PTXs) are a superfamily of proteins highly involved in different myocardial disorders, and thus this study aimed to identify the modulation of long pentraxin 3 (PTX3) in the differentiation of mouse embryonic stem cells (mESCs) toward cardiomyocytes. Cell toxicity of PTX3 was detected by MTT and LDH assays in mESCs. Embryoid bodies (EBs) were differentiated using hanging drop method, and the beating was observed under microscope. Expressional levels of early cardiac progenitor marker genes were assessed by qRT-PCR. Expression of marker proteins in early myocardial development and the activation of JNK signaling pathway was evaluated by Western blot. PTX3 treatment at 50 ng/mL significantly promoted the expression of cardiac-specific marker genes including Nkx2.5, Mef2c, Tbx5, dHand, and αMHC, and increased the expression of cardiac maturity indicative markers including connexin 43 and troponin C1. PTX3 enhanced the phosphorylation of JNK across the incubation duration, whereas the activation of p38 remained the same as control group. Co-treatment of JNK signaling pathway inhibitor SP600125 impaired the PTX3-promoted transcription of Nkx2.5, Mef2c, Tbx5, dHand, and αMHC. This study revealed the promotion of PTX3 in the differentiation of mESCs into cardiomyocytes and the underlying mechanism.

Abstract
The prevalence of chronic kidney disease (CKD) is high in patients with atrial fibrillation (AF). Left atrial appendage closure (LAAC) has been recognized as an efficient alternative to oral anticoagulation for the prevention of thromboembolic events in patients with non-valvular AF (NVAF); however, the long-term safety and efficacy of LAAC in patients with CKD remain unclear. This study was designed to provide data regarding the safety and efficacy of LAAC in NVAF patients with CKD. A real-world analysis of the safety and efficacy of LAAC was performed on a cohort of 300 NVAF patients with or without CKD who underwent LAAC using the Watchman (WM) device at our center. The patients with CKD (n = 151) were significantly older (77.0 ± 7.2 vs. 73.2 ± 7.8 years, respectively, P < 0.0001) and had a higher CHA2DS2-VASc score (4.3 ± 1.5 vs. 3.4 ± 1.4, respectively, P < 0.0001) and HAS-BLED score (4.0 ± 1.0 vs. 3.0 ± 1.0, respectively, P < 0.0001) than the patients without CKD (n = 149). However, there were no differences between groups with respect to the device implant success rate (98.7 vs. 97.3%, respectively, P = 0.446) or severe periprocedural complications within 7 days. The patients were followed up for 637 ± 398 days, and all patients received repeat transesophageal echocardiography (TEE). Thirteen (4.3%) device-related thrombi, 3 (1.0%) ischemic strokes, and 19 (6.3%) non-procedural major bleeding cases were documented, and there were no differences in these complications between groups. The observed rate of all thromboembolic events by Kaplan–Meier analysis decreased by 68.8% (CKD) and 48.6% (non-CKD); moreover, the observed annual rate of bleeding was reduced by 57.5% (CKD) and 11.4% (non-CKD). Our results indicate that LAAC with the WM device is safe and effective in preventing stroke in NVAF patients with and without CKD.

Abstract
We evaluated the efficacy and safety of tacrolimus (TAC) combined with corticosteroids in treating patients with idiopathic membranous nephropathy (IMN). One hundred seventy-seven biopsy-proven IMN patients were recruited in this retrospective clinical study. Sixty patients received TAC (target blood concentration of 4–8 ng/mL) and 117 patients received daily cyclophosphamide (CYC, 100 mg) combined with prednisone. Remission rates at the end of the first, second and third month in the TAC group were significantly higher than that in the CYC group (1st: 35.0 vs 19.7%, P<0.05; 2nd: 56.7 vs 38.5%, P<0.05; 3rd: 76.7 vs 59.0%, P<0.05). In the first 3 months, daily urinary protein and serum albumin in the TAC group obtained a better improvement than that in the CYC group (P<0.05). At the end of the sixth and the twelfth month, the remission rates, daily urinary protein and serum albumin were all comparable between the two groups (P>0.05). No significant difference of relapse rate between the groups was found (16.3 vs 12.0%, P>0.05). Patients were more likely to develop glucose intolerance in the TAC group. The TAC regimen obtained more benefits in treating IMN patients, especially in the first 3 months, than the CYC regimen.

Abstract
Objective: To discuss the surgical treatment and efficacy of endoscopic nipple-sparing mastectomy with skin lifting system (ENSMSLS) followed by immediate breast reconstruction. Methods: ENSMSLS was conducted on 21 patients followed by immediate breast reconstruction with implant via axillary incision from August 2014 to January 2016 in Oncology Center, Beijing Tongren Hospital, Capital Medical University. These 21 patients were frequency matched with 21 patients, who received nipple-sparing mastectomy via loop periareolar incision from November 2012 to May 2015 in the same center. These 21 patients formed the control group. The operation data of two groups were compared by t test and Fisher's exact test. Results: Differences in operation time ((185±43) minutes vs. (165±33) minutes, t=1.778, P=0.101), amount of bleeding ((60±48) ml vs. (75±57) ml, t=-0.535, P=0.329), and drainage ((240±112) ml vs. (201±91) ml, t=1.238, P=0.233) between these two groups of patients were not statistically significant. There was no nipple necrosis recorded in the ENSMSLS group, while there were three cases (14.3%) recorded in the control group. Two cases (9.5%) of nipple transposition were recorded in the ENSMSLS group, while five cases (23.8%) were recorded in the control group. Differences in nipple necrosis and nipple transposition were statistically significant (0 vs. 5, P=0.001). There were 16 cases (76.2%) of excellent appearance recorded in the ENSMSLS group, while there were 11 cases (52.4%) recorded in the control group. There were 5 cases (23.8%) of good appearance recorded in the ENSMSLS group, while there were 9 cases (42.9%) recorded in the control group. There was no case of fair appearance in the ENSMSLS group, while there was 1 case (4.8%) recorded in the control group. Difference in postoperative appearance was statistically significant (P=0.001). Conclusions: ENSMSLS significantly decreases the possibility of nipple necrosis and nipple transposition. This technique avoids visible incisions of breast. It also enhances the aesthetic appeal of reconstructed breasts.

Abstract
OBJECTIVES To explore the relationship of general health decline assessed by frailty and risk of dementia and Alzheimer's disease (AD). DESIGN A seven-year prospective cohort study. SETTING Secondary analysis of data from the Beijing Longitudinal Study on Aging. PARTICIPANTS Urban and rural community-dwelling people aged 60 and older at baseline. MEASUREMENTS Frailty was quantified using the deficit accumulation-based frailty index (FI), constructed from 40 health deficits at baseline. Dementia was diagnosed by DSM-IIIR. AD and vascular dementia (VaD) were diagnosed by NINCDS-ADRDA and NINDS-AIREN. The relationships between frailty and the risk of dementia, AD and death were evaluated through multivariable models. RESULTS Of 2788 participants at baseline (1997), 171 (11.1%) reported a history of dementia. In seven years, 351 people developed dementia (13%: 223 AD and 128 other types of dementia) and 813 died (29%). After adjustment for age, sex, education, and baseline cognition, baseline frailty status significantly associated with Alzheimer's disease and dementia and death. For each deficit accumulated, the odds ratio of death increased by 5.7%, and the odds ratio of dementia increased by 2.9% (p < 0.001). CONCLUSION Frailty was associated with Alzheimer's disease and dementia over a seven years period. Frailty index might facilitate the identification of older adults at high risk of dementia for the application of the most effective, targeted prevention strategies.

Abstract
Acute myocardial infarction is one of the leading causes for death around the world. Although essential for successful interventional therapy, it is inevitably complicated by reperfusion injury. Thus effective approaches to reduce ischemia/reperfusion (I/R) injury are still critically needed. To test our hypothesis that intravenous administration of NAD(+) can attenuate I/R injury by reducing apoptotic damage and enhancing antioxidant capacity, we used a rat mode of myocardial I/R. Our study found that administration of 10-20 mg/kg NAD(+) can dose dependently reduce myocardial infarct induced by I/R, with an approximately 85% reduction of the infarct at the dosage of 20 mg/kg NAD(+). We further found that the injection of NAD(+) can significantly decrease I/R-induced apoptotic damage in the heart: NAD(+) administration can both decrease the TUNEL signals, Bax, cleaved caspase-3 levels and increase the Bcl-XL levels in the rats that are subjected to myocardial I/R injury. NAD(+) administration can also significantly attenuate I/R-induced decreases in SOD activity and SOD-2 protein levels in the hearts. NAD(+) can profoundly decrease myocardial I/R injury at least partially by attenuating apoptotic damage and enhancing the antioxidant capacity, thus suggesting that NAD(+) may become a promising therapeutic agent for myocardial I/R injury.

Abstract
Since hepatitis C virus (HCV) non-structural 3 (NS3) protease inhibitor (PI) combined with pegylated interferon/ribavirin (PR) has been approved for chronic HCV genotype (GT) 1b infection, a reliable and clinically useful predictor combining with serum HCV RNA to predict early virologic response, breakthrough, and relapse is important during HCV antiviral treatment. We evaluated the role of HCV NS3 antigen (HCV NS3Ag) on the prediction of virologic response in patients with HCV GT1b during PR or PR/simeprevir (triple) therapy. Three hundred patients were recruited, and HCV RNA and HCV NS3Ag were tested at baseline and weeks 2, 4, 12, 24, 48, and 72. NS3Ag and HCV RNA were significantly related (r(2) = 0.67) in the whole patient selection. The kinetic pattern of HCV RNA and HCV NS3Ag during triple treatment was similar. HCV NS3Ag levels in the triple group closely followed those of HCV RNA; the r(2) values were 0.756 (baseline), 0.837 (2 weeks), 0.989 (4 weeks), and 0.993 (12 weeks), respectively. For patients treated with PR, the positive and negative predictive values (PPVs and NPVs) for viral response were 96.31 % and 67.19 %, respectively, at week 4 by using the decrease of NS3Ag (dHCV NS3Ag) combined with HCV RNA. At week 12, the PPV was similar at 94.16 %, while the NPV reached 87.26 %. The PPV and NPV for the prediction of relapse and breakthrough were 90.6 % and 76.7 %, respectively. HCV NS3Ag is a valuable marker and could be a supplementary predictor of HCV RNA for the prediction of antiviral response, breakthrough, or relapse during HCV antiviral treatment.

Abstract
AIM To report the results of two phase III trials assessing the efficacy of ranolazine for glycaemic control in patients with type 2 diabetes on metformin or glimepiride background therapy. METHODS In two double-blind trials we randomized 431 and 442 patients with type 2 diabetes to ranolazine 1000 mg twice daily versus placebo added to either glimepiride (glimepiride add-on study) or metformin background therapy (metformin add-on study). Patients receiving ranolazine added to metformin had their metformin dose halved (with the addition of a metformin-matched placebo) relative to the placebo group to correct for a metformin-ranolazine pharmacokinetic interaction. The primary endpoint of the trials was the change from baseline in glycated haemoglobin (HbA1c) at week 24. RESULTS When added to glimepiride, ranolazine caused a 0.51% least squares mean [95% confidence interval (CI) 0.71, 0.32] decrease from baseline in HbA1c at 24 weeks relative to placebo and roughly doubled the proportion of patients achieving an HbA1c of <7% (27.1 vs 14.1%; p = 0.001). When added to metformin background therapy, there was no significant difference in the 24-week HbA1c change from baseline [placebo-corrected LS mean difference -0.11% (95% CI -0.31, 0.1)]. CONCLUSIONS Compared with placebo, addition of ranolazine in patients with type 2 diabetes treated with glimepiride, but not metformin, significantly reduced HbA1c over 24 weeks. The decreased dose of metformin used in the metformin add-on study complicates the interpretation of this trial. Whether an effective regimen of ranolazine added to metformin for glycaemic control can be identified remains unclear.

Abstract
Perinereis aibuhitensis is a commercially and ecologically important intertidal worm. In this study, eight polymorphic microsatellite loci were isolated in this species for the first time, and a wild population was used to estimate the properties of these loci. The number of alleles per locus ranged from 6 to 20, and the observed and expected heterozygosities ranged from 0.375 to 0.875 and from 0.590 to 0.946, respectively. These microsatellite loci will act as effective markers for related P. aibuhitensis studies, and the data will be helpful for the rational exploitation and conservation of this species.

Abstract
A continuous germanene layer grown on the Al (111) surface has recently been achieved in experiment. In this work, we investigate its structural, electronic, and hydrogenation-induced properties through first-principles calculations. We find that despite having a different lattice structure from its free-standing form, germanene on Al (111) still possesses Dirac points at high-symmetry K and K' points. More importantly, there exist another three pairs of Dirac points on the K(K')-M high-symmetry lines, which have highly anisotropic dispersions due to the reduced symmetry. These massless Dirac Fermions become massive when spin-orbit coupling is included. Hydrogenation of the germanene layer strongly affects its structural and electronic properties. Particularly, when not fully hydrogenated, ferromagnetism can be induced due to unpaired local orbitals from the unsaturated Ge atoms. Remarkably, we discover that the one-side semihydrogenated germanene turns out to be a two-dimensional half-semimetal, representing a novel state of matter that is simultaneously a half-metal and a semimetal.

Abstract
An integration of virtual screening and kinase assay was reported to identify AMPK kinase inhibitors from various natural medicines.The activation of AMP-activated protein kinase (AMPK) signalling pathway plays a central role in the pathologic progression of atherosclerosis (AS). Targeting the AMPK is thus considered as a potential therapeutics to attenuate AS. Here, we report the establishment of a synthetic pipeline that integrates in silico virtual screening and in vitro kinase assay to discover new lead compounds of AMPK inhibitors. The screening is performed against a large-size pool of structurally diverse natural products, from which a number of compounds are inferred as promising candidates, and few of them are further tested in vitro by using a standard kinase assay protocol to determine their inhibitory potency against AMPK. With this scheme we successfully identify five potent AMPK inhibitors with IC50 values at micromolar level. We also examine the structural basis and molecular mechanism of nonbonded interaction network across the modelled complex interface of AMPK kinase domain with a newly identified natural medicine.

Abstract
OBJECTIVE To investigate the associations between plasma levels of pentraxins 3 (PTX3) and C reactive protein (CRP) and the severity of coronary artery lesions. DESIGN AND METHODS 60 patients with coronary heart disease (CHD) who underwent coronary angiography (CAG) in our hospital were included. Plasma was collected during CAG. The coronary Gensini score was used to evaluate the severity of coronary artery lesions. Associations between Gensini scores and plasma levels of PTX3 and CRP were analysed. Patients with estimated glomerular filtration rate <60 mL/min/1.73 m(2) were included in the chronic renal dysfunction subgroup. RESULTS A linear correlation was observed between PTX3 and the Gensini score (r=0.513, p<0.001). One-way analysis of variance showed that PTX3 levels were significantly higher in patients with Gensini scores >90 compared with patients with scores of 46-90 or <45 (0-45:4.8±0.8, 46-90:6.7±1.2, >90:7.7±2.0, p<0.001). Stepwise multiple linear regression showed that PTX3 levels were significantly associated with Gensini score in patients with chronic renal dysfunction (p=0.012), while no significant association was found for CRP. CONCLUSIONS PTX3 levers were positively associated with the severity of coronary artery lesions. PTX3 is closely associated with the severity of coronary artery stenosis in patients with chronic renal dysfunction.

Abstract
Accurate assessment of coronary chronic total occlusion (CTO) lesion is essential to design an appropriate procedural strategy before revascularization. The present study aims to evaluate the significance of a single multislice computed tomography (MSCT) examination in patients with CTO lesion. We retrospectively analyzed the clinical data of 23 CTO lesions in twenty patients underwent computed tomography coronary angiography (CTCA) and SPECT. The CTCA was more powerful and sensitive to determine the CTO lesion length (100% v.s 47.8%) and to identify the length and location of calcification in occluded vessels compared with the coronary angiography (CAG). The LVEF measured by MSCT was comparable to that from the gated SPECT. Myocardial perfusion imaging showed that the location of the early defect region identified by MSCT was corresponded to the nuclide filling defect on the stressed 201thallium-SPECT imaging. The late hyperenhancement on MSCT was presented as incomplete nuclide filling on the 99mTc-MIBI imaging. The results suggested that a single MSCT examination in previous myocardial infarction without revascularization facilitates to provide some valuable information on the nature of the occluded lesion, myocardial perfusion and globe cardiac function, which would be helpful to design appropriate revascularization strategy in these subjects.
