Abstract
Biocomplex materials formed by oppositely charged biopolymers (proteins) tend to be sensitive to environmental conditions and may lose part functional properties of original proteins, and one of the approaches to address these weaknesses is protein modification. This study established an electrostatic composite system using succinylated ovalbumin (SOVA) and ε-polylysine (ε-PL) and investigated the impact of varying degrees of succinylation and ε-PL addition on microstructure, environmental responsiveness and functional properties. Molecular docking illustrated that the most favorable binding conformation was that ε-PL binds to OVA groove, which was contributed by the multi‑hydrogen bonding and hydrophobic interactions. Transmission electron microscopy observed that SOVA/ε-PL had a compact spherical structure with 100 nm. High-degree succinylation reduced complex sensitivity to heat, ionic strength, and pH changes. ε-PL improved the gel strength and antibacterial properties of SOVA. The study suggests possible uses of SOVA/ε-PL complex as multifunctional protein complex systems in the field of food additives.

Abstract
The implementation of a laparoscope-holding robot in minimally invasive surgery enhances the efficiency and safety of the operation. However, the extra robot control task can increase the cognitive load on surgeons. A suitable interface may simplify the control task and reduce the surgeon load. Foot interfaces are commonly used for commanding laparoscope-holding robots, with two control strategies available: decoupled control permits only one Cartesian axis actuation, known as decoupled commands; hybrid control allows for both decoupled commands and multiple axes actuation, known as coupled commands. This paper aims to determine the optimal control strategy for foot interfaces by investigating two common assumptions in the literature: (1) Decoupled control is believed to result in better predictability of the final laparoscopic view orientation, and (2) Hybrid control has the efficiency advantage in laparoscope control. Our user study with 11 experienced and trainee surgeons shows that decoupled control has better predictability than hybrid control, while both approaches are equally efficient. In addition, using two surgery-like tasks in a simulator, users' choice of decoupled and coupled commands is analysed based on their level of surgical experience and the nature of the movement. Results show that trainee surgeons tend to issue more commands than the more experienced participants. Single decoupled commands were frequently used in small view adjustments, while a mixture of coupled and decoupled commands was preferred in larger view adjustments. A guideline for foot interface control strategy selection is provided.

Abstract
The aim of this investigation was to scrutinize the effects of a thermal treatment on the electrostatic complex formed between gum arabic (GA) and ε-polylysine (ε-PL), with the goal of improving the antibacterial properties and reducing the hygroscopicity of ε-PL. The heated complex with a ratio of 1:4 exhibited an encapsulation efficiency of 93.3%. Additionally, it had an average particle size of 350.3 nm, a polydispersity index of 0.255, and a zeta potential of 18.9 mV. The formation of the electrostatic complex between GA and ε-PL was confirmed through multispectral analysis, which demonstrated the participation of hydrogen bonding and hydrophobic and electrostatic interactions, as well as the enhanced effect of heat treatment on these forces within the complex. The complex displayed a core-shell structure, with a regular distribution and a shape that was approximately spherical, as observed in the transmission electron microscopy images. Additionally, the heated GA-ε-PL electrostatic composite exhibited favorable antibacterial effects on Salmonella enterica and Listeria monocytogenes, with reduced minimum inhibitory concentrations (15.6 μg/mL and 62.5 μg/mL, respectively) and minimum bactericidal concentrations (31.3 μg/mL and 156.3 μg/mL, respectively) compared to free ε-PL or the unheated electrostatic composite. Moreover, the moisture absorption of ε-PL reduced from 92.6% to 15.0% in just 48 h after being incorporated with GA and subsequently subjected to heat. This research showed a way to improve the antibacterial efficiency and antihygroscopicity of ε-PL, reducing its application limitations as an antimicrobial substance to some extent.

Abstract
Objective: To investigate the impact of COVID-19 on treatment of patients with acute ST segment elevation myocardial infarction(STEMI) undergoing primary percutaneous coronary intervention(PPCI). Methods: This was a multicenter retrospective study. STEMI patients undergoing PPCI from January 1, 2019 to December 31, 2021 were selected, based on the data of Xinnaolvsetongdao App. Clinical data and treatment time indicators, including symptom to first medical contact (S-FMC), symptom to door (StoD), first medical contact to ECG (FMC-ECG), first medical contact to guide wire (FMC-W), door to balloon (DtoB) and total ischemic time in 2019, 2020 and 2021 were compared. STEMI patients aged<60 years were sub-grouped as the young and middle-aged group, and STEMI patients aged≥60 years were sub-grouped as the elderly group. Results: A total of 7 435 (3 305 in 2019, 1 796 in 2020 and 2 334 in 2021) STEMI patients aged (59.6±12.6) years undergoing PPCI were included in this analysis. There were 5 990 males. For STEMI patients with PPCI in 2019, 2020 and 2021, FMC-ECG was 3 (1, 5) min, 3(1, 7) min and 4 (1, 7) min. FMC-W was 73 (56, 87) min, 78 (62, 95) min and 77 (62, 87) min. DtoB was 73 (56, 85) min, 78 (62, 95) min and 77 (62, 86) min. Total ischemic time was 189 (130, 273) min, 196 (138, 295) min and 209 (143, 276) min. FMC-ECG, FMC-W, DtoB and total ischemic time were longer in 2020 and 2021 than in 2019 (all P<0.05). The proportions of patients with FMC-ECG≤10 min (88.4% (1 588/1 796) vs. 92.7% (3 064/3 305), P<0.05), FMC-W≤120 min (87.9% (1 579/1796) vs. 91.7% (3 030/3 305), P<0.05) and DtoB≤90 min (72.3% (1 298/1 796) vs. 80.8% (2 672/3 305), P<0.05) were lower in 2020 than in 2019, whereas no differences were observed in the proportions of patients with FMC-ECG≤10 min (91.3% (2 131/2 334) vs. 92.7% (3 064/3 305), P=0.054), FMC-W≤120 min (92.0% (2 148/2 334) vs. 91.7% (3 030/3 305), P=0.635) and DtoB≤90 min (80.0% (1 867/2 334) vs. 80.8% (2 672/3 305), P=0.424) in 2021 compared with 2019. In the subgroup analysis, the proportions of patients with FMC-ECG≤10 min, FMC-W≤120 min and DtoB≤90 min were lower in the elderly group than in young and middle-aged group in 2019 (all P<0.05). The proportions of patients with FMC-W≤120 min and DtoB≤90 min were lower in the elderly group than in young and middle-aged group in 2021(all P<0.05). No differences were observed in the proportions of patients with FMC-ECG≤10 min, FMC-W≤120 min and DtoB≤90 min between the two group in 2020 (all P>0.05). Conclusions: Affected by the COVID-19, there is a reduction in the number of PPCI cases and treatment delays in STEMI patients, especially in the elderly. After adjusting the treatment strategy and widely applying the Xinnaolvsetongdao APP, the above indicators are significantly improved in 2021 as compared with 2020.

Abstract
Objective: To investigate the clinical features and long-term prognostic factors of diabetic patients with low or intermediate complexity coronary artery disease (CAD) post percutaneous coronary intervention (PCI). Methods: This was a prospective, single-centre observational study. Consecutive diabetic patients with SYNTAX score (SS)≤32 undergoing PCI between January and December 2013 in Fuwai hospital were included in this analysis. The patients were divided into two groups based on SS, namely SS≤22 group and SS 23-32 group. Multivariate Cox regression analysis was performed to identify independent factors related to poor 5-year prognosis. The primary outcomes were cardiac death and recurrent myocardial infarction, the secondary outcomes were all cause death and revascularization. Results: Of the 3 899 patients included in the study, 2 888 were men (74.1%); mean age was 59.4±9.8 years. There were 3 450 patients in the SS≤22 group and 449 patients in the SS 23-32 group. Compared with SS≤22 group, the incidence of revascularization was higher in SS 23-32 group (18.9% (85/449) vs. 15.2% (524/3450), log-rank P=0.019). There was no significant difference in all-cause death, cardiac death and recurrent myocardial infarction between the two groups (log-rank P>0.05). Multivariate Cox regression analysis showed that age (HR=1.05, 95%CI 1.02-1.08, P<0.001), chronic obstructive pulmonary disease (HR=3.12, 95%CI 1.37-7.07, P=0.007) and creatinine clearance rate (CCr)<60 ml/min (HR=3.67, 95%CI 2.05-6.58, P<0.001) were independent risk factors for 5-year cardiac death, while left ventricular ejection fraction (HR=0.94, 95%CI 0.91-0.96, P<0.001) was a protective factor. Previous PCI (HR=2.04, 95%CI 1.38-3.00, P<0.001), blood glucose level≥11.1 mmol/L on admission (HR=2.49, 95%CI 1.32-4.70, P=0.005) and CCr<60 ml/min (HR=1.85, 95%CI 1.14-2.99, P=0.012) were independent risk factors for 5-year recurrent myocardial infarction. The SS of 23-32 was independently associated with risk of revascularization (HR=1.54, 95%CI 1.09-2.16, P=0.014), after adjusting for residual SS. Residual SS was not a risk factor for 5-year prognosis. Conclusions: In diabetic patients with low-or intermediate complexity CAD, SS 23-32 is associated with increased risk of 5-year revascularization; the clinical characteristics of the patients are associated with the long-term mortality and recurrent myocardial infarction, but not related to revascularization.

Abstract
Objective: To investigate the current situation of cell phone use and sleep quality among college students, establish a sleep quality trajectory model and explore the influence of cell phone use on the sleep quality trajectory. Methods: Based on data from the College Student Behavior and Health Cohort Study 2019-2020, a latent class growth modeling was used to establish a sleep quality trajectory model among college students. The baseline influencing factors of sleep quality trajectories among college students were analyzed by χ2 test, and the effects of cell phone use on sleep quality trajectories were analyzed by binary logistic regression. Results: A total of 1 092 college students were included in the analysis. The detection rates of cell phone use and poor sleep quality were 24.5% and 13.3%. Latent class growth model identified two groups of sleep quality trend trajactories: an improved sleep quality group (86.0%) and a decreased sleep quality group (14.0%). The result of binary logistic regression showed that the cell phone use was a risk factor of sleep quality trajectories. Conclusion: The cell phone use during college period could increase the risk of poor sleep quality. Targeted intervention measures about cell phone use should be adopted to improve the sleep quality among college students.

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
There are many kinds of pharmaceutical preparations for children in China, which are generally divided into oral solid preparations and oral liquid preparations. Solid preparations, such as microtablets, pellets, dispersible tablets, and fine granules, have become the development trend of pediatric drugs. Liquid preparations mainly include syrup, suspension, oral solution, and drops. The poor taste and the treatment of drugs in children of different ages are the key factors affecting the efficacy, safety, and compliance of pediatric drugs. To reduce the risk caused by the fluctuation of blood concentration and improve the oral compliance of pediatric drugs, it is urgent to develop new techniques for granulation and flavor maskingto improve the poor taste of solid preparations. For liquid pre-parations with poor taste, the flavor correction technique should be used. This paper summarized the new pharmaceutical techniques for granulation and flavor masking, and it was found that sustained/controlled-releasegranules, fine granules, and chewing solid mini-tablets became the mainstream of oral solid preparations for children. Generally, multiparticle preparation, coating, microencapsulation, and other granulating techniques were involved in these preparations. Granulation and flavor masking are closely related and synergetic. Flavor masking techniques mask the bitter taste of Chinese medicine from four aspects, including confusing the brain taste, changing the compounds, reducing the exposure of bitter molecules to bitter receptors in the mouth, and numbing the taste cells to increase the threshold of bitter perception. At present, the main drugs for children on the market mainly inhibit the oral release of bitter drugs.

Abstract
This study aimed to forecast the main active components of Xiaoer Chiqiao Qingre Granules(XECQ) in the treatment of children with acute upper respiratory tract infection by UPLC-MS, network pharmacology, molecular docking and cell biology, and explore the mechanism of action, so as to provide certain reference for the research on its pharmacodynamics substances and mechanism of action. The main chemical components of XECQ were comprehensively analyzed by UPLC-Q-TOF-MS combined with UNIFI platform. According to the MS1 and MS2 data of XECQ, comparison and identification were carried out in combination with reference substances and reference articles. On this basis, the chemical components of XECQ were targeted and enriched by network pharmacology, to screen the main pharmacodynamic substances of XECQ in the treatment of acute upper respiratory tract infection in children and discuss the mechanism of action. In addition, the binding degree of core targets and main active components was verified by molecular docking. The results revealed that 202 compounds were identified from XECQ, among which 22 were the main active components, including obovatol, dihydroartemisinin, and longikaurin A. Enrichment analysis of the key target pathways showed that XECQ played its role in the treatment of children with acute upper respiratory tract infection mainly by regulating PI3K/Akt signaling pathway and MAPK signaling pathway. In the experimental verification by Western Blot(WB), it was found that XECQ significantly inhibited the expression of PI3K and Akt, which was consistent with the prediction results of network pharmacology. In conclusion, the potential pharmacodynamic substances of XECQ were obovatol, dihydroartemisinin, longikaurin A and other 19 active components. It treated children with acute upper respiratory tract infection by regulating the PI3K/Akt signaling pathway.

Abstract
This study aimed to elucidate the digestive characteristics of flavonoid components in Xiaoer Chiqiao Qingre Granules(XECQ) in the gastrointestinal environment of infants. An in vitro model was established to simulate the gastric and intestinal environment of infants. UPLC was used to analyze the content change of flavonoid components in XECQ, and their overall content was integrated through the mass fraction weight coefficient method. UPLC-Q-TOF-MS was employed to determine the digestive products of flavonoid components in gastrointestinal fluids and their metabolic pathways. The results showed that in the process of digestion, 11 digestion products were generated by oxidation, reduction, deglycosylation, methylation and other phase Ⅰ metabolism. From flavonoid content and component changes, it was found that the flavonoid components in XECQ were relatively stable in the gastric fluid, while their content in the intestinal fluid was first increased and then maintained stable. This was mainly because flavonoid components were released from proteins, polysaccharides and other macromolecular substances during gastrointestinal digestion. In addition, phase Ⅰ metabolism occurred, but with relatively low metabolic rate, resulting in their stable content. This study preliminarily explored the digestive characteristics of flavonoid components in XECQ in the infant gastrointestinal environment, which laid a foundation for further studying the absorption, transport and metabolism of pharmacodynamics components in XECQ, and facilitated the study of the biopharmaceutical pro-perties of pediatric Chinese medicine.

Abstract
Mineral medicine is a characteristic element of advantage of traditional Chinese medicine(TCM), which embodies unique scientific connotation. Cinnabaris is a characteristic drug in Chinese medicinal preparations, especially in Chinese medicinal pediatric preparations. Because of the adverse reactions caused by mercury contained, the safety and application of Cinnabaris have attracted much attention. To explore the application regularity and the value of the pediatric preparations containing Cinnabaris, this study statistically analyzed 32 Cinnabaris-contained pediatric preparations in the 2020 edition of the Chinese Pharmacopoeia and 105 pediatric preparations containing Cinnabaris in the Dictionary of Traditional Chinese Medicine Prescriptions(Vol. Ⅰ and Ⅱ). The statistical results indicated that the pediatric preparations and formulae containing Cinnabaris had great advantages in the treatment of pediatric convulsions, but there were still problems in dosage form, dosage, and quality control. In this study, ICP-MS and LC-AFS were further used to determine the content of total mercury and soluble mercury in 15 commercially available pediatric preparations containing Cinnabaris. It was found that the total mercury content was far higher than soluble mercury content in the sample preparations, and there was no obvious correlation between them. According to the results, the research and application strategies of Cinnabaris were put forward in order to provide references for the rational application of Cinnabaris in pediatric preparations.

Abstract
Pediatric medication in China is characterized by a lack of child-specific drugs and insufficient types, specifications, dosage forms, and delivery devices. In recent years, new dosage forms with good compliance, such as inhalation preparation, rectal delivery system, and transdermal delivery system, have attracted more attention in pediatric medication. Because of the physiological characteristics of delicate viscera, difference in swallowing ability and psychological characteristics of fear of pain and aversion to bitter taste, it is particularly important to select suitable drug delivery route and drug delivery device according to children's physiological characteristics. With the help of the special drug delivery devices, traditional Chinese medicine and innovative Chinese medicine can be administered according to the expected design path, and drug delivery devices can ensure the accurate dose and improve the complia-nce to achieve the purpose of effective and safe drug delivery. It is also a way to realize the re-innovation of traditional Chinese medicine. The present study summarized the research progress in drug delivery devices for common drug delivery routes and new drug deli-very routes, put forward the innovative design idea of children's drug delivery devices according to the special needs of children, poin-ted out the compatibility of drug delivery devices and other problems in the current development, and prospected the application of intelligent information technology and additive manufacturing technology in drug delivery device innovation. This is expected to provide references for the development of innovative drugs and drug delivery devices suitable for children's multidimensional demand for medication.

Abstract
To clarify the metabolic transformation mechanism of phenylethanoid glycosides in Xiaoer Chiqiao Qingre Granules in vivo, this study extracted and separated the phenylethanoid glycosides in Xiaoer Chiqiao Qingre Granules. Based on UPLC-Q-TOF-MS/MS technology, the retention time and primary and secondary mass spectrometry information were analyzed by UNIFI software, and 11 phenylethanoid glycosides in Xiaoer Chiqiao Qingre Granules were preliminarily identified. Sixty-nine metabolites related to phenylethanoid glycosides were identified from the plasma samples of juvenile rats after administration of Xiaoer Chiqiao Qingre Granules. In addition, this study simulated the transformation system of intestinal flora in children, and discussed the metabolic effects of intestinal flora on the representative components forsythoside A, forsythoside E, and salidroside of phenylethanoid glycosides. The model of gastrointestinal heat retention in children with food accumulation was established to study the differential metabolites of phenylethanoid glycosides. Through the comparative analysis of the representative components absorbed in blood and the intestinal floral transformation products, it was found that the main metabolic pathways of phenylethanoid glycosides were dehydrogenation, oxidation, acetylation, sulfation, and glucuronidation. The findings of this study revealed the transformation law of phenylethanoid glycosides in the gastrointestinal tract. Through the preliminary discussion of the pharmacological mechanism, this study provides references for further clarifying the pharmacodynamic material basis of Xiaoer Chiqiao Qingre Granules and exploring the pediatric Chinese medicine compound.

Abstract
In this study, the secondary osteoporosis model was induced by oral administration of retinoic acid for two weeks in SD male rats. The efficacy and mechanism of LG on secondary osteoporosis in rats were explored through the bone morphogenetic protein 2(BMP-2)/Runt-related transcription factor 2(Runx2)/Osterix signaling pathway. With Xianling Gubao Capsules(XLGB) as the positive control, three dose groups of low glycoside from Epimedii Folium flavonoids(LG), i.e., low-dose group(LG-L), medium-dose group(LG-M), and high-dose group(LG-H), were set up. After modeling, the rats in each group were treated correspondingly by gavage for eight weeks. The action target of LG in the treatment of secondary osteoporosis in rats was analyzed by measuring the body weight and the organ indexes of rats including heart index and testis index. The efficacy of LG was characterized by the pathological changes of the femur, the microstructural parameters of the trabecular bone, and the biomechanical properties of femoral tissues in rats. The mechanism of LG was explored by measuring the relevant biochemical indexes and the changes in BMP-2, Runx2, and Osterix content in rats with secondary osteoporosis. The results showed that the action target of LG in the treatment of secondary osteoporosis in rats was the testis. LG can improve the bone loss of the femur, increase the number and thickness of the trabecular bone, reduce the porosity and separation of the trabecular bone, potentiate the resistance of bone to deformation and destruction, up-regulate the serum content of Ca, P, aminoterminal propeptide of type Ⅰ procollagen(PINP), and osteocalcin(OC), promote bone matrix calcification and the expression of BMP-2, Runx2, and Osterix proteins, and accelerate bone formation, thereby reducing the risk of fractures, and ultimately exerting anti-secondary osteoporosis efficacy.

Abstract
Epimedii Folium possesses many pharmacological activities including immunomodulation, anti-oxidation, and anti-tumor. Polysaccharides are the main components of Epimedii Folium, and their activities are closely related to the structure. The present study isolated a neutral polysaccharide(EPS-1-1) and an acidic polysaccharide(EPS-2-1) from the aqueous extract of Epimedii Folium through DEAE-52 cellulose anion-exchange chromatography and Sephadex G-100. The structures were characterized by chemical composition analysis, high-performance gel permeation chromatography(HPGPC), Fourier-transform infrared spectrometry(FT-IR), 1-phenyl-3-methyl-5-pyrazolone(PMP) derivatization, scanning electron microscopy(SEM), Congo red test, etc. The immunomodulatory activity of polysaccharides in vitro was determined by investigating the effects on the maturation of bone marrow-derived dendritic cells(BMDCs) and the release of inflammatory cytokines. According to the structural characterization analysis, EPS-1-1 was composed of fructose(Fuc), mannose(Man), ribose(Rib), rhamnose(Rha), glucose(Glc), galactose(Gal), xylose(Xyl), and arabinose(Ara) at 1.90∶0.67∶0.05∶0.08∶3.29∶1.51∶0.05∶0.37(molar ratio), while EPS-2-1 was mainly composed of Fuc, Man, Rha, glucuronic acid(GlcA), galacturonic acid(GalA), Glc, Gal, Xyl, and Ara at 5.25∶0.18∶0.32∶0.13∶1.14∶0.16∶0.55∶0.08∶0.2. EPS-1-1 and EPS-2-1 could promote the maturation and function of BMDCs through up-regulating the expression of MHC-Ⅱ, CD86, CD80, and CD40, and increasing the levels of inflammatory cytokines(IL-6, IL-12, and TNF-α) in vitro experiments, which suggested that EPS-1-1 and EPS-2-1 possessed good immunomodulatory activity.

Abstract
The present study explored the optimum synthesis process of Rehmannia glutinosa seleno-polysaccharides with acetic acid as a catalyst, characterized the structure of R. glutinosa seleno-polysaccharides by Fourier transform infrared spectroscopy(FT-IR), scanning electron microscopy(SEM), thermogravimetry(TG), and atomic force microscopy(AFM), and preliminarily investigated the immunological activity of R. glutinosa seleno-polysaccharides. The results showed that the optimal conditions for the synthesis of R. glutinosa seleno-polysaccharides included m(acetic acid)∶m(R. glutinosa polysaccharides)=0.80, m(Na_2SeO_3)∶m(R. glutinosa polysaccharides)=1.25, reaction temperature of 80.0 ℃, and reaction time of 7.0 h. Under these conditions, the selenium content of R. glutinosa seleno-polysaccharides was 2.239 mg·g~(-1). The acetic acid catalysis method was milder than the nitric acid method, without affecting the structure of polysaccharides. The results of IR, SEM, TG, and AFM showed that R. glutinosa seleno-polysaccharides were properly prepared. The results of immunological activity showed that compared with the control group, R. glutinosa seleno-polysaccharides could significantly promote the phagocytic capacity of mouse monocyte macrophages and improve the spleen index and thymus index of mice. In the concentration range of 15-240 μg·mL~(-1), the proliferation of spleen lymphocytes of mice was strengthened, and the IL-2 and IFN-γ secretion by Th1 cytokines was promoted. This study can provide references for the further development and application of R. glutinosa polysaccharides.

Abstract
Objective: To explore and compare the effect of standard or prolonged dual antiplatelet therapy (DAPT) on the long-term prognosis of elderly patients with coronary heart disease complicated with diabetes mellitus after drug-eluting stent (DES) implantation. Methods: Consecutive patients with diabetes mellitus, ≥65 years old, underwent DES implantation, and had no adverse events within 1 year after operation underwent percutaneous coronary intervention (PCI) from January to December 2013 in Fuwai Hospital were enrolled in this prospective cohort study. These patients were divided into three groups according to DAPT duration: standard DAPT duration group (11 ≤ DAPT duration≤ 13 months) and prolonged DAPT duration group (13<DAPT duration≤ 24 months; DAPT duration>24 months). All the patients were followed up at 1, 6 months, 1, 2 and 5 years in order to collect the incidence of major adverse cardiovascular and cerebrovascular events (MACCE), and type 2 to 5 bleeding events defined by the Federation of Bleeding Academic Research (BARC). MACCE were consisted of all cause death, myocardial infarction, target vessel revascularization or stroke. The incidence of clinical adverse events were compared among 3 different DAPT duration groups, and Cox regression model were used to analyze the effect of different DAPT duration on 5-year long-term prognosis. Results: A total of 1 562 patients were enrolled, aged (70.8±4.5) years, with 398 female (25.5%). There were 467 cases in standard DAPT duration group, 684 cases in 13<DAPT duration≤ 24 months group and 411 cases in DAPT duration>24 months group. The patients in standard DAPT duration group and the prolonged DAPT duration groups accounted for 29.9% (467/1 562) and 70.1% (1 095/1 562), respectively. The 5-year follow-up results showed that the incidence of all-cause death in 13<DAPT duration≤ 24 months group (4.8%(33/684) vs. 8.6%(40/467),P=0.011) and DAPT duration>24 month group(4.1%(17/411) vs. 8.6%(40/467),P=0.008) were significantly lower than in standard DAPT group. The incidence of myocardial infarction in 13<DAPT duration≤ 24 months group was lower than in standard DAPT duration group (1.9%(13/684) vs. 5.1%(24/467),P=0.002). The incidence of MACCE in 13<DAPT duration≤ 24 months group was the lowest (standard DAPT duration group, 13<DAPT duration≤ 24 months group and DAPT duration>24 month group were 19.3% (90/467), 12.3% (84/684), 20.2% (83/411), respectively, P<0.001). There was no significant difference in the incidence of stroke and bleeding events among the three groups (all P>0.05). Multivariate Cox analysis showed that compared with the standard DAPT group, prolonged DAPT to 13-24 months was negatively correlated with MACCE (HR=0.601, 95%CI 0.446-0.811, P=0.001), all-cause death (HR=0.568, 95%CI 0.357-0.903, P=0.017) and myocardial infarction (HR=0.353, 95%CI 0.179-0.695, P=0.003). DAPT>24 months was negatively correlated with all-cause death (HR=0.687, 95%CI 0.516-0.913, P=0.010) and positively correlated with revascularization (HR=1.404, 95%CI 1.116-1.765, P=0.004). There was no correlation between prolonged DAPT and bleeding events. Conclusions: For elderly patients with coronary heart disease complicated with diabetes mellitus underwent DES implantation, and had no MACCE and bleeding events within 1 year after operation, appropriately prolonging of the DAPT duration is related to the reduction of the risk of cardiovascular adverse events. Patients may benefit the most from the DAPT between 13 to 24 months. In addition, prolonging DAPT duration does not increase the incidence of bleeding events in this patient cohort.

Abstract
Due to the complex source and different physical and chemical properties of traditional Chinese medicines(TCM) powder, there are many common pharmaceutical problems in its preparation, such as large particle size difference, poor mixing uniformity, and poor compliance with oral intake, which has directly affected the quality of solid preparations as well as their clinical efficacy and safety. This study observed the property of Zhuhuang Chuihou Powder and extract its pharmaceutical defects. It was found that realgar and calcined Borax in Zhuhuang Chuihou Powder were heavy in texture and toxic, and they were easy to be isolated, indicating the potential safety hazard. At the same time, Coptidis Rhizoma and Phellodendri Chinensis Cortex were the main sources of its bitterness. Therefore, based on the idea of "drug-excipients unity", the particle design technology was used to prepare core/shell-type composite particles with bitter medicines as the core and mineral medicines as shell. Both infrared spectroscopy and scanning electron microscopy results indicated the formation of composite particles, and the taste of these composite particles were improved. Compared with the physical mixtures, the composite particles exhibited significantly decreased RSD values in the content uniformity of berberine hydrochloride, arsenic disulfide, and sodium tetraborate and appearance uniformity. The introduction of particle design technology solved the problem of uneven dispersion of Zhuhuang Chuihou Powder, thus ensuring its uniform dispersion, stability, and control and improving the quality of the original preparation. This has provided a scientific basis for the quality control of TCM powder.

Abstract
Targeting the deficiencies of Lingzhu Powder, this study introduced the particle design technology to improve its quality. Based on the mechanism of particle design for powder and the characteristics of solvent evaporation method, composite particles consisting of Succinum, Cinnabaris, and artificial Bovis Calculus were prepared. And the powder properties of composite particles and physical mixtures as well as the content uniformity of toxic components were investigated for exploring the technological advantages of particle design in improving the quality of Lingzhu Powder. The results showed that the composite particles prepared using solvent evaporation method and particle design technology were micro-particles, and the stable agglomerate structure could be observed under SEM. Composite particles exhibited better fluidity and compliance in oral intake than physical mixtures. The differences in chromatism, bulk density, and content uniformity of the composite particles were smaller than those of physical mixtures, and the corresponding RSD values \[4.8%, 1.8%, 3.4%(bilirubin), and 0.63%(HgS), respectively\] were smaller. The solvent evaporation combined with particle design technology can be utilized to significantly improve the quality of Lingzhu Powder, which has provided new ideas for the optimization of the quality of traditional Chinese medicinal powder.

Abstract
In conventional Minimally Invasive Surgery, the surgeon conducts the operation while a human or robot holds the laparoscope. Laparoscope control is returned to the surgeon in teleoperated camera holding robots, but simultaneously controlling the laparoscope and surgical tools might be cognitively demanding. On the other hand, fully automated camera holders are still limited in their performance. To help the surgeon to better focus on the main operation while maintaining their control authority, we propose an automatic laparoscope zoom factor control framework for Robot-Assisted Minimally Invasive Surgery. In this paper, we present the perception section of the framework. It extracts and uses the surgical tool's geometric characteristics to adjust the laparoscope's zoom factor, without any artificial markers. The acceptable range and tooltip's position frequency during operations are analysed based on the gallbladder removal surgery dataset (Cholec80). The common range and tooltip's heatmap are identified and presented quantitatively.

Abstract
Objective: To establish a novel nomogram to predict overall survival of patients with gastric neuroendocrine neoplasms (g-NEN). Methods: A case control study was conducted. Clinicopathological and follow-up data of patients with g-NEN who were treated in two academic medical centers in Southern China between July 2008 and June 2018 were retrospectively collected, including 174 patients from Sun Yat-sen University Cancer Center and 102 patients from the First Affiliated Hospital of Sun Yat-sen University. Univariate survival analysis using Kaplan-Meier method and multivariate analysis using Cox regression were performed to identify prognostic factors. A nomogram was subsequently established based on prognostic factors. Harrell's concordance index (C-index), receiver operating characteristic (ROC) curve, calibration curve and decision curve analysis (DCA) were used to verify the performance of the model according to differentiation, calibration and clinical utility. Results: A total of 276 patients were enrolled in the study, of whom 189 patients were male and 87 were female. The age at diagnosis was below 60 years old in 150 patients and 60 years or older in 126 patients. There were patients diagnosed with gastric neuroendocrine carcinoma (g-NEC) and 101 patients with gastric neuroendocrine tumor (g-NET). The number of patients with primary tumor locating at upper, middle and lower parts of stomach was 131, 98 and 47, respectively. As for TNM stage, 72 patients were categorized as stage I, 26 patients stage II, 93 patients stage III, and 85 patients stage IV. Univariate analysis indicated that age, pathological type, primary site, Ki-67 index, T stage, N stage, and M stage were associated with overall survival of g-NEN patients (all P<0.05). Multivariate regression analysis testified that high Ki-67 index, advanced T stage and advanced M stage were independent prognostic factors (all P<0.05). The C-index of the nomogram was 0.806 (95%CI: 0.769-0.863). The calibration curve of the nomogram showed that the predicted survival rate was consistent with the actual survival rate in g-NEN patients. The ROC curves and DCA showed that the nomogram had better differentiation and clinical utility than the American Joint Committee on Cancer (AJCC) 8th TNM staging system (the area under the ROC curve was 0.862 vs. 0.792). Conclusion: The first nomogram to predict overall survival of patients with g-NEN is established and verified in this study, which provides individual prediction of 3-year overall survival rate and is applicable to both g-NET and g-NEC patients.

Abstract
Abstract
Background
In euthyroid patients undergoing percutaneous coronary intervention (PCI), it is still unclear whether thyroxin deiodination level can predict the recurrence of cardiovascular events (CVEs). Using free triiodothyronine to free thyroxine (FT3/FT4) ratio, a marker of peripheral thyroxin deiodination, we aim to investigate its association with recurrent long-term adverse events in this population.
Methods
3549 euthyroid patients with prior CVEs history undergoing PCI were consecutively enrolled in our study and subsequently divided into three FT3/FT4 ratio tertiles (T1<2.41, n=1170; 2.41≤T2<2.75, n=1198; T3>2.75, n=1181). The primary endpoint was major adverse cardiovascular and cerebrovascular event (MACCE), a composite of all-cause death, myocardial infarction, stroke and revascularization. The secondary endpoints were all-cause death and cardiac death.
Results
The median follow-up time was 5 years. The incidence of all-cause death, cardiac death and MACCE were significantly higher among patients in the lowest FT3/FT4 tertile (P<0.05). After adjustment of confounding factors, decreased FT3/FT4 ratio was independently associated with an increased risk of all-cause death (HR 1.82, 95% CI 1.13–2.93, P=0.014), cardiac death (HR 1.90, 95% CI 1.04–3.46, P=0.036) and MACCE (HR 1.33, 95% CI 1.10–1.60, P=0.003).
Conclusions
In euthyroid patients undergoing PCI, FT3/FT4 ratio, a surrogate marker of peripheral thyroxin deiodination, demonstrates a strong association with long-term recurrent cardiovascular events. Routine assessment of FT3/FT4 ratio might be a simple and effective tool for risk stratification in this specific patient population.

Abstract
Abstract
Background
Microvascular endothelial injury is recently considered playing an initial role in myocardial ischemia/reperfusion injury (MIRI). Cardiac microvascular endothelial cells (CMECs) regulate cardiomyocytes and haematocytes via secreting cytokine. MIRI jeopardize not only the barrier function but also the paracrine function of microvasculature. Resveratrol, a natural polyphenolic compound, was demonstrated to protect myocardium against MIRI and to preserve the function of endothelium. However, how the paracrine function of CMECs is regulated by MIRI and resveratrol remains to be elucidated.
Purpose
The study was to illuminate the alteration of cytokine profiles secreted by CMECs under hypoxia/reoxygenation (H/R) condition and its modulation by resveratrol.
Methods
CMECs were exposed to different concentrations of resveratrol for 30 minutes and then were subjected to H/R for 12 h/2 h. Apoptotic rates were measured to determine the optimal concentration. Protein antibody arrays were performed to find the alteration of cytokine secreted into conditioned medium by CMECs. A Gene Ontology (GO) analysis was applied to interpret the functional implication of changes in cytokine profiles.
Results
Resveratrol inhibited apoptosis of CMECs in a dose-dependent manner after H/R and reached its peak effect at the concentration of 100μM, which reduced apoptosis from 27.27±2.95% to 15.01±1.36% (Figure 1A and B). The results of a cluster analysis and all significantly altered factors are shown in figure 1C (fold-change >1.5; p<0.05). Twenty-nine types of cytokine were significantly changed by H/R (15 factors decreased and 14 increased, Figure 2A), and resveratrol at 100μM changed 98 types of cytokine compared with the H/R group (93 factors decreased and 5 increased, Figure 2B). Among these cytokine, eight factors were increased by H/R and they were decreased by resveratrol. Eleven were attenuated by H/R and further decreased by resveratrol. Insulin-like growth factor binding protein-1 was up-regulated by H/R and it was further increased by resveratrol (Figure 2C). The factors with significant alteration were involved in cellular growth, proliferation and differentiation, as well as chemotaxis and transport.
Conclusions
Resveratrol inhibited the apoptosis of CMECs and modulated the paracrine function of cardiac microvascular endothelium under ischemia/reperfusion condition.

Abstract
Abstract
Background
DNA 5-hydroxymethylcytosine (5hmC) modification is an epigenetic marker involved in a range of biological processes. However, little information is available about its role in coronary artery disease (CAD), particularly in the acute phase of acute coronary syndrome (ACS).
Aims
To investigate whether 5hmC modification correlates with the pathogenesis and progression of CAD and whether 5hmC in cfDNA can be used as biomarkers.
Methods
We utilized 5hmC-Seal to generate genome-wide 5hmC profiles in plasma cell-free DNA (cfDNA) of normal coronary artery (NCA, n=200) controls and CAD patients, including stable coronary artery disease (sCAD, n=200) patients and ACS patients (n=371). To investigate the correlation between 5hmC modifications and CAD subtypes, we separated samples into training and validation cohorts and developed a 5hmC-based logistic regression model from the training cohort to predict the progression of CAD in the validation cohort.
Results
We detected a significant difference of 5hmC enrichment in gene bodies from CAD patients compared with NCA individuals. Particularly, our results showed that patients of CAD subgroups can be well separated from NCA individuals by 5hmC markers. The prediction performance of the model established by differentially regulated 5hmC modified genes achieved an AUC of 0.81 (sCAD vs. NCA) and 0.74 (ACS vs. NCA) in validation cohorts.
Conclusions
Our results demonstrated that patients of CAD subtypes and NCA individuals had distinct differences in 5hmC enrichment. 5hmC markers derived from plasma cfDNA may potentially serve as a clinical-applicable, minimally invasive, and liquid biopsy-based approach to diagnose CAD, particularly used to predict the occurrence of fetal ACS.

Abstract
Abstract
Background
The prognosis for patients with coronary artery disease (CAD) remains unfavorable despite advances in treatment. Fibrinogen (FIB) is an independent risk factor for mortality and cardiovascular events in general population. However, the relationship between FIB and long-term mortality among CAD patients undergoing PCI is less investigated, especially in individuals concomitated with diabetes mellitus (DM) and prediabetes (Pre-DM).
Methods
6140 patients with CAD undergoing PCI were consecutively enrolled in our study and subsequently divided into three groups according to FIB levels (FIB-L, FIB-M, FIB-H). These patients were further grouped by glycemic metabolism state [normoglycemia (NG), Pre-DM, DM]. The primary endpoint was all-cause mortality. The secondary endpoint was cardiac mortality.
Results
FIB was positively associated with hemoglobin A1c (HbA1c) and fasting blood glucose (FBG) both in CAD patients with and without DM. During a median follow-up time of 5.1 years, elevated FIB was significantly associated with long-term mortality from all-cause (adjusted HR: 1.86; 95% CI: 1.28–2.69; P=0.001) and cardiac specific (adjusted HR: 1.82; 95% CI: 1.15–2.89; P=0.011). Similarly, patients with DM but not Pre-DM had increased risk of all-cause and cardiac mortality (all P<0.05). When grouped by both FIB levels and glycemic metabolism state, diabetic patients with medium and high FIB levels had higher risk of mortality [(adjusted HR: 2.57; 95% CI: 1.12–5.89), (adjusted HR: 3.04; 95% CI: 1.35–6.82), all P<0.05]. Notably, prediabetic patients with high FIB also had higher mortality risk (adjusted HR: 2.27; 95% CI: 1.01–5.12).
Conclusion
FIB was strongly associated with long-term all-cause and cardiac mortality among CAD patients undergoing PCI, especially in persons concomitated with DM and Pre-DM, indicating FIB test may help identify high-risk individuals in this specific patient population.

Abstract
As an excellent foaming agent, egg white protein (EWP) is always contaminated by egg yolk in the industrial processing, therefore, decreasing its foaming properties. The aim of this study was to simulate the industrial EWP (egg white protein with 0.5% w/w of egg yolk) and characterize their foaming and structural properties when hydrolyzed by two types of esterase (lipase and phospholipase A2). Results showed that egg yolk plasma might have been the main fraction, which led to the poor foaming properties of the contaminated egg white protein compared with egg yolk granules. After hydrolyzation, both foamability and foam stability of investigated systems thereof (egg white protein with egg yolk, egg white protein with egg yolk plasma, and egg white protein with egg yolk granules) increased significantly compared with unhydrolyzed ones. However, phospholipids A2 (PLP) seemed to be more effective on increasing their foaming properties as compared to those systems hydrolyzed by lipase (LP). The schematic diagrams of yolk fractions were proposed to explain the aggregation and dispersed behavior exposed in their changes of structures after hydrolysis, suggesting the aggregated effects of LP on yolk plasma and destructive effects of PLP on yolk granules, which may directly influence their foaming properties.

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 evaluate the acute and long-term outcome of patients with ST segment elevation myocardial infarction (STEMI) concurrent with chronic total occlusion (CTO) undergoing primary percutaneous coronary intervention (PCI). Methods: 11 905 STEMI patients from the China Acute Myocardial Infarction Registry were enrolled in this study and divided into CTO group and non-CTO group according to the angiography results of primary PCI. 1∶3 propensity score matching was used to match the patients between the two groups. The primary endpoint was in-hospital mortality and mortality at 1-year post PCI. The secondary endpoint was major adverse cardiovascular events (MACE) including death, re-myocardial infarction, revascularization, heart failure associated readmission, stroke and major bleeding at 1-year post PCI. Results: There were 931 CTO patients (7.8%) in this cohort (male=755 (81.1%), mean age (62.2±11.4 years)). The rest 10 974 patients were STEMI without CTO (male=8 829 (80.5%),mean age (60.0±11.8) years). After propensity score matching, 896 patients were enrolled in CTO group and 2 688 in non-CTO group. In-hospital mortality was significantly higher in the CTO group than in non-CTO group (4.2% vs. 2.4%, P=0.006). The ratio of all cause death, cardiac death, and MACE at 1-year follow up was also significantly higher in the CTO group than in non-CTO group (8.5% vs. 4.4%, P<0.001, 5.3% vs. 2.6%, P=0.001, 35.1% vs. 23.3%, P<0.001, respectively). Multiple regression analysis showed that CTO (HR=1.54, 95%CI 1.06-2.22, P=0.022), advanced age (HR=1.06, 95%CI 1.04-1.08, P<0.001), and previous heart failure history (HR=4.10, 95%CI 1.90-8.83, P<0.001) were independent risk factors of 1-year mortality. Conclusions: The in-hospital and 1-year mortality increased significantly in STEMI patients concurrent with CTO. CTO, advanced age and history of heart failure are independent risk factors of 1-year death among STEMI patients.

Objective We sought to assess the relative merits of different revascularization strategies in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease complicated by cardiogenic shock or chronic total occlusion (CTO). Background Recent randomized trials and meta-analysis have suggested that multivessel percutaneous coronary intervention (PCI) is associated with better outcomes in patients with STEMI and multivessel coronary artery disease, however, patients complicated by cardiogenic shock or CTO were excluded. Methods Studies that compared multivessel PCI (immediate or staged) with culprit-only PCI in patients with STEMI and multivessel coronary artery disease complicated by cardiogenic shock or CTO were included. Random odd ratio (OR) and 95% confidence interval (CI) were conducted. Results Sixteen studies with 8695 patients complicated by cardiogenic shock and eight studies with 2259 patients complicated by CTO were included. In patients complicated by cardiogenic shock, a strategy of CO-PCI was associated with lower risk for short-term renal failure (OR: 0.75; 95% CI: 0.61 to 0.93; I2 = 0.0%), with no significant difference in MACE, all-cause mortality, re-infarction, revascularization, cardiac death, heart failure, major bleeding, or stroke compared with an immediate MV-PCI strategy. In patients complicated by CTO, a strategy of CO-PCI was associated with higher risk for long-term MACE (OR: 2.06; 95% CI: 1.39 to 3.06; I2 = 54.0%), all-cause mortality (OR: 2.89; 95% CI: 2.09 to 4.00; I2 = 0.0%), cardiac death (OR: 3.12; 95% CI: 2.05 to 4.75; I2 = 16.8%), heart failure (OR: 1.99; 95% CI: 1.22 to 3.24; I2 = 0.0%), and stroke (OR: 2.80; 95% CI: 1.04 to 7.53; I2 = 0.0%) compared with a staged MV-PCI strategy, without any difference in re-infarction, revascularization, or major bleeding. Conclusions For patients with STEMI and multivessel coronary artery disease complicated by cardiogenic shock, an immediate multivessel PCI was not advocated due to higher risk for short-term renal failure, whereas for patients complicated by CTO, a staged multivessel PCI was advocated due to reduced risks for MACE, all-cause mortality, cardiac death, heart failure, and stroke.

Background
Patients with diabetes mellitus (DM) are known to be at high-risk for both ischemic and bleeding complications post-percutaneous coronary intervention (PCI). The ischemic benefit versus bleeding risk associated with extended dual antiplatelet therapy (DAPT) in high-risk "TWILIGHT-like" patients with diabetes mellitus after PCI has not been established.
Methods
All consecutive high-risk patients fulfilling the "TWILIGHT-like" criteria undergoing PCI from January 2013 through December 2013 were identified from prospective Fuwai PCI Registry. High-risk "TWILIGHT-like" patients were defined by at least 1 clinical and 1 angiographic feature based on TWILIGHT trial selection criteria. The present analysis evaluated 3425 diabetics patients with concomitant high-risk angiographic features who were event-free at 1 year after PCI. Median follow-up was 2.4 years. The primary effectiveness endpoint was a composite of death, myocardial infarction, or stroke (termed major adverse cardiac and cerebrovascular events) and primary safety endpoint was clinically relevant bleeding according to Bleeding Academic Research Consortium type 2, 3, or 5.
Results
On inverse probability of treatment weighting (IPTW) analysis, prolonged-term (>1-year) DAPT with aspirin and clopidogrel decreased the risk of primary effectiveness endpoint compared with shorter (≤1-year) DAPT (1.8% vs. 4.3%; hazard ratio [HR]IPTW: 0.381; 95% confidence interval [CI]: 0.252-0.576; P < 0.001) and reduced cardiovascular death (0.1% vs. 1.8%; HRIPTW: 0.056 [0.016-0.193]). Prolonged DAPT was also associated with a reduced risk of definite/probable stent thrombosis (0.2% vs. 0.7%; HRIPTW: 0.258 [0.083-0.802]), and non-significantly lower rate of myocardial infarction (0.5% vs. 0.8%; HRIPTW: 0.676 [0.275-1.661]). There was no significant difference between groups in clinically relevant bleeding (1.1% vs. 1.1%; HRIPTW: 1.078 [0.519-2.241]; P = 0.840). Similar results were observed in multivariable Cox proportional hazards regression model.
Conclusion
Among high-risk PCI patients with diabetes mellitus without an adverse event through 1 year, extending DAPT > 1-year significantly reduced the risk of major adverse cardiac and cerebrovascular events without an increase in clinically relevant bleeding, suggesting that such high-risk diabetic patients may be good candidates for long-term DAPT.

Abstract
Objective: To investigate the feasibility and safety of fetal intravascular transfusion via the intrahepatic vein in the treatment of fetal anemia. Methods: This was a retrospective analysis of all fetuses requiring intrauterine transfusion (IUT) in the Shanghai First Maternity and Infant Hospital between January 2010 and December 2019. According to the different ways of IUT, they were divided into intrahepatic venous transfusion group and umbilical venous transfusion group, fetal outcomes and the incidence of procedure-related complications between the two groups were compared. Results: A total of 97 IUTs were performed on 48 fetuses. Among them, 16 cases were performed in the intrahepatic vein (31 transfusions), 32 cases were performed in the cord of the umbilical vein (66 transfusions).There were no significant differences between the two groups in age, labor history and the proportion of fetal hydrops before the first transfusion. In the intrahepatic venous transfusion group, the posterior placenta was 14/16, which was significantly higher than 78% (25/32) in the umbilical venous transfusion group (P<0.01). The live-birth rates of the two groups were 13/16 and 75% (24/32). There was no significant difference between the two groups (P>0.05). Before intrahepatic venous transfusion, the proportion of fetal hydrops was significantly higher than that of umbilical venous transfusion [55% (17/31) vs 24% (16/66), P<0.05]. Puncture success rate of intrahepatic venous transfusion and umbilical venous transfusion were both 100%. In the umbilical venous transfasion group, the incidence of needle slippage (5%, 3/66) and the abnormality of fetal heart rate (11%, 7/66) were higher than those in the intrahepatic venous transfasion group [0 and 3% (1/31)], but there were no significant differences between the two groups (all P>0.05). There were no cases of fetal loss within 24 hours, premature rupture of membranes, infection within 7 days and emergency cesarean section after IUT in both groups. Conclusions: Fetal intravascular transfusion via the intrahepatic vein is safe and feasible in the treatment of fetal anemia. But the requirements of puncture technique are relatively high, so it is recommended to be carried out in experienced fetal treatment center.

Background
Whether the underlying risk of high bleeding risk (HBR) influences the relationship of high ischemic risk (HIR) features with adverse events after drug-eluting stent implantation remains unclear. The purpose of this study was to evaluate (1) the prognostic effect of ESC guideline-endorsed HIR features on long-term clinical outcomes and (2) whether the outcomes of HIR versus non-HIR features vary by HBR status.
Methods
Ten thousand one hundred sixty-seven consecutive patients who underwent percutaneous coronary intervention between January 2013 and December 2013 were prospectively enrolled in Fuwai PCI Registry. Patients who are at HIR were defined as: diffuse multivessel disease in diabetic patients, chronic kidney disease, at least three stents implanted, at least three stents lesions treated, bifurcation with two stents implanted, total stent length > 60 mm, or treatment of chronic total occlusion. The definition of HBR was based on the Academic Research Consortium (ARC) for HBR criteria. The primary ischemic outcome was major adverse cardiac event (MACE), a composite of cardiac death, myocardial infarction, target vessel revascularization and stent thrombosis. The primary bleeding outcome was clinically relevant bleeding, defined according to Bleeding Academic Research Consortium (BARC) type 2, 3 or 5 bleeding.
Results
With a 2.4-year median follow-up, 4430 patients (43.6%) having HIR experienced a significantly higher risk of MACE (hazard ratio [HR] adjust : 1.56, 95% confidence interval [CI]: 1.34–1.82; P < 0.001) and device-oriented composite endpoint (composite of cardiac death, target-vessel MI, and target lesion revascularization) (HRadjust : 1.52 [1.27–1.83]; P < 0.001), compared to those having non-HIR. The risk of clinically relevant bleeding did not differ between groups (HRadjust : 0.85 [0.66–1.08]; P = 0.174). Associations between HIR and adverse events were similar in HBR and non-HBR groups, without evidence of interaction (all P interaction > 0.05); however, adverse event rates were highest among subjects with both HIR and HBR.
Conclusions
ESC guideline-endorsed HIR was associated with significantly increased risk of MACE without any significant differences in clinically relevant bleeding. The presence of ARC-HBR does not emerge as a modifier of cardiovascular risk for patients at HIR, suggesting more potent and longer antiplatelet therapy may be beneficial for this patient population.

Abstract
One 51 years old man was admitted to the rheumatology department with a history of prominent eyes, headache and blurred vision for half year. The main manifestations included retrobulbar inflammatory pseudotumor and retroperitoneal fibrosis. He was initially diagnosed as granulomatosis with polyangiitis. Prednisone and cyclophosphamide were administrated and effective. New mass of dura mater and osteosclerosis presented during follow up. Finally Erdheim Chester disease(ECD) was diagnosed by biopsy and pathological examination. Vemurafenib, a v-raf murine sarcoma viral oncogenes homolog B1 (BRAF) inhibitor, 480 mg was given twice a day. The patient's condition is stable and still in follow-up. Although ECD is a rare histiocytosis, clinicians should pay attention to its manifestations and differential diagnoses.

Abstract
Brassica campestris L. is the important oil-bearing crop in China. Rapeseed cake is the main byproduct of rapeseed oil extraction. As the main active ingredient in rapeseed cake, sinapine has several important biological activities. Therefore, the inhibitory activity of sinapine on tyrosinase in vitro and its free radical-scavenging rate were determined. Tyrosinase activity in A-375 human melanocytes was also investigated and the effects of sinapine on the melanin content and its antioxidant effects on melanin biosynthesis were studied. The results showed that sinapine had significant antioxidant activity. Sinapine significantly inhibited A-375 human melanocytes in a dose-dependent manner. Sinapine inhibited melanin synthesis in A-375 cells by downregulating the mRNA and protein expression of TRP-1, TRP-2, and MITF factors. The results showed that rapeseed cake sinapine inhibited melanin production and could be used as a potential active ingredient in the development of whitening agents.

Abstract
Objective: To explore the related factors of premature acute myocardial infarction(AMI), and to compare the the long-term outcomes in patients with and without premature AMI after percutaneous coronary intervention (PCI). Methods: This study was a prospective cohort study.From January 2013 to December 2013, 10 724 consecutive patients with coronary heart disease undergoing PCI in Fuwai Hospital were enrolled. Among them 1 920 patients with the diagnosis of AMI were divided into two groups: premature AMI (man≤50 years old, woman≤60 years old) and non-premature AMI. The baseline characteristics were collected, and multivariate logistic regression was uesed to analysis the related factors of premature AMI. The clinical outcomes, including the major adverse cardiovascular and cerebrovascular events(MACCE) which was the composite of cardiac death, myocardial infarction, revascularization, stroke and stent thrombosis, as well as bleeding events, during hospitalization, at 2 years and 5 years follow-up were analyzed. Results: A total of 1 920 AMI patiens were included(age was (56.5±11.3) years old),with 1 612(84.0%) males. There were statistically significant differences between the two groups in gender, body mass index, blood lipid, complications, inflammatory markers, etc (all P<0.05). Multivariate logistic regression analysis showed body mass index(OR=1.06, 95%CI 1.01-1.10, P<0.01), triglyceride(OR=1.47, 95%CI 1.14-1.90, P<0.01), serum uric acid level(OR=1.02, 95%CI 1.01-1.04, P<0.01), high density lipoprotein cholesterol level(OR=0.33, 95%CI 0.14-0.78, P=0.01) and history of hypertension(OR=0.72, 95%CI 0.56-0.93, P=0.01) were independent related factors of premature AMI. The incidence of all-cause death and cardiac death were lower during hospitalization, at 2 years and 5 years follow-up in the premature AMI group than in non-premature AMI group(all P<0.05). In the premature AMI group, the incidence of MACCE and stroke was lower, with more bleeding events in 5 years follow-up(all P<0.05). Conclusions: Metabolic abnormalities, including high BMI, high triglyceride level and high serum uric acid, low high-density lipoprotein cholesterol level are the related factor of premature AMI. The incidence of ischemic events in patients with premature AMI is lower, while the incidence of bleeding events is higher than non-premature AMI patients.

Abstract
OBJECTIVE Long non-coding RNAs are an emerging special class of regulatory RNAs with more than 200 nucleotides that play vital roles in gene regulation, metabolism, drug resistance, cell differentiation, and other processes. These RNAs were also reported to be dysregulated in human disease, especially malignant tumors. However, the underlying mechanisms remain elusive. HOXD cluster antisense RNA 1 (HOXD-AS1), a recently discovered long non-coding RNA, is overexpressed in many cancers. We now review recent advances in understanding the function, role, regulation, and oncogenic properties of HOXD-AS1. MATERIALS AND METHODS A systematic literature review in PubMed of HOXD-AS1 and cancer-related articles in English, published until June 2018, was conducted. RESULTS The literature suggests that HOXD-AS1 is an oncogene that regulates diverse physiological and cellular processes such as proliferation, apoptosis, migration, invasion, metastasis, chemoresistance, epithelial to mesenchymal transition, and stem cell formation by interacting with various regulatory proteins and sequestering several microRNAs such as miR-608, miR-130a, and miR-217. CONCLUSIONS HOXD-AS1 may be a prognostic biomarker and potential therapeutic target for various tumor diagnosis and treatment.

Abstract
OBJECTIVE Lingzhu San (LZS) is a traditional Chinese medicine (TCM) prescription which can be effective in treating febrile seizures (FS) and has few researches on the mechanisms. In order to better guide the clinical use of LZS, we used the research ideas and methods of network pharmacology to find the potential core compounds, targets and pathways of LZS in the complex TCM system for the treatment of FS, and predict the mechanism. MATERIALS AND METHODS Databases such as BATMAN, TCMSP, TCMID, and SWISS TARGET are used to mine the active compounds and targets of LZS, and the target information of FS was obtained through GENECARDS and OMIM. Using Venny2.1.0 and Cytoscape software to locked the potential core compounds and targets of FS. The R language and ClusterProfiler software package were adopt to enrich and analyze the KEGG and GO pathways of the core targets and the biological processes and potential mechanisms of the core targets were revealed. RESULTS 187 active compounds and 2113 target proteins of LZS were collected. And 38 potential core compounds, 35 core targets and 775 metabolic and functional pathways were screened which involved in mediating FS. Finally, the role of the core compounds, targets and pivotal pathways of LZS regulated FS in the pathogenesis and therapeutic mechanism of FS was discussed and clarified. CONCLUSIONS In this paper, the multi-compounds, multi-targets and multi-pathways mechanism of LZS in the treatment of FS was preliminarily revealed through the analysis of network pharmacology data, which is consistent with the principle of multi-compounds compatibility of TCM prescriptions and unified treatment of diseases from multiple angles, and it provides a new way for TCM to treat complex diseases caused by multiple factors.

Abstract
OBJECTIVE To describe differences in outcomes between pregnant women with and without coronavirus dsease 2019 (COVID-19). DESIGN Prospective cohort study of pregnant women consecutively admitted for delivery, and universally tested via nasopharyngeal (NP) swab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using reverse transcription-polymerase chain reaction. All infants of mothers with COVID-19 underwent SARS-CoV-2 testing. SETTING Three New York City hospitals. POPULATION Pregnant women >20 weeks of gestation admitted for delivery. METHODS Data were stratified by SARS-CoV-2 result and symptomatic status, and were summarised using parametric and nonparametric tests. MAIN OUTCOME MEASURES Prevalence and outcomes of maternal COVID-19, obstetric outcomes, neonatal SARS-CoV-2, placental pathology. RESULTS Of 675 women admitted for delivery, 10.4% were positive for SARS-CoV-2, of whom 78.6% were asymptomatic. We observed differences in sociodemographics and comorbidities among women with symptomatic COVID-10 versus asymptomatic COVID-19 versus no COVID-19. Caesarean delivery rates were 46.7% in symptomatic COVID-19, 45.5% in asymptomatic COVID-19 and 30.9% in women without COVID-19 (P = 0.044). Postpartum complications (fever, hypoxia, readmission) occurred in 12.9% of women with COVID-19 versus 4.5% of women without COVID-19 (P < 0.001). No woman required mechanical ventilation, and no maternal deaths occurred. Among 71 infants tested, none were positive for SARS-CoV-2. Placental pathology demonstrated increased frequency of fetal vascular malperfusion, indicative of thrombi in fetal vessels, in women with COVID-19 versus women without COVID-19 (48.3% versus 11.3%, P < 0.001). CONCLUSION Among pregnant women with COVID-19 at delivery, we observed increased caesarean delivery rates and increased frequency of maternal complications in the postpartum period. Additionally, intraplacental thrombi may have maternal and fetal implications for COVID-19 remote from delivery. TWEETABLE ABSTRACT COVID-19 at delivery: more caesarean deliveries, postpartum complications and intraplacental thrombi.

Abstract
Objective: To analyze the clinical and prognostic characteristics in patients with eosinophilic granulomatosis with polyangitis (EGPA). Methods: The clinical data of 146 EGPA patients hospitalized in Peking Union Medical College Hospital from 2000 to 2019 were analyzed retrospectively, including clinical manifestations, laboratory results, treatment, complications and outcome at discharge. Birmingham Vasculitis activity score-V3 (BVAS-V3) was used to evaluate disease activity. Results: The ratio of male to female was 1.8∶1 with average age (41.7±16.1) year-old. The median time from disease onset to diagnosis was 18(6, 60) months (0.5~450). The most common clinical manifestations were lung [121(82.9%)] and nose/paranasal sinuses [119(81.5%)] involvement. The positive rate of anti-neutrophil cytoplasmic antibody (ANCA) was 24.7%, mainly peripheral (P)-ANCA/myeloperoxidase (MPO)-ANCA. Compared with ANCA-negative patients, the ANCA-positive patients had a higher incidence of renal involvement and nervous system involvement (66.7% vs. 20.9%, 80.6% vs. 51.8%, P<0.001), fever and optic neuropathy (66.7% vs. 40.9%,8.3% vs. 0, P<0.05), more active disease [median BVAS-V3 25(18,30)vs. 19(14,24),P=0.001] and more elevated erythrocyte sedimentation rate [40.5(20.5,82.8)mm/1h vs. 25.0(13.3,50.8)mm/1h,P=0.006] and C-reactive protein [37.1(11.8,72.9)mg/L vs.13.5(3.4,66.1)mg/L,P=0.036]. More ANCA-negative patients had pleural effusion (20.9% vs. 5.6%, P<0.04) compared with ANCA-negative patients. Pulmonary infection was the most common complication. A total of 12 EGPA patients (8.2%)achieved remission and 6 patients (4.1%)died or discharged themselves from the hospital. Conclusion: EGPA is a rare small vessel vasculitis. The clinical manifestations and outcomes are heterogenous. The mortality rate of EGPA is high.

Abstract
Objective: To investigate the impact of metabolic syndrome (MS) and its individual components on long-term prognosis of patients undergoing percutaneous coronary intervention(PCI). Methods: Patients who underwent PCI in Fuwai Hospital in 2013 were enrolled and divided to two groups: with MS and without MS. The primary endpoint of 2-year follow-up was major adverse cardiovascular events (MACE), including death, myocardial infarction, and repeat revascularization. Results: Of the 10 422 PCI patients, there were 5 656 (54.27%) without MS and 4 766 (45.73%) with MS. Patients in the MS group were younger, tended to be male and had more comorbidities. There were no significant differences between the two groups in the proportion of drug-coated stents and the success rate of interventional therapy. The 2-year follow-up showed that the incidence of MACE in the MS group was significantly higher than that in the MS-free group (12.0% vs 10.0%, P<0.001), which was mainly due to the significantly higher revascularization rate in the MS group than in the non-MS group (9.5% vs 7.9%, P=0.003). Cox's regression analysis showed that MS was an independent risk factor for MACE. In MS component analysis, abnormal glucose metabolism was an independent risk factor for MACE events. Conclusions: Among the patients undergoing PCI, the incidence of MACE in patients with MS is significantly higher than that in patients without MS, and MS was an independent risk factor for MACE. In addition, hyperglycemia is an independent predictor for MACE.

Abstract
Objective: To explore the end criteria of forced vital capacity(FVC) curve in adults. Methods: A multicenter cross-sectional study was performed in Zhongshan Hospital Affiliated to Fudan University, the First Affiliated Hospital of Fujian Medical University, and the Third Affiliated Hospital of Inner Mongolia Medical University from January 2017 to August 2017. A consecutive sample of subjects who completed the spirometry test and FVC curves met end criteria of no volume change (<0.025 L) for ≥ 1 s were qualified in this study. Subjects were divided into a normal group (n=610), an obstructive group (n=536), and a restrictive group(n=306) according to pulmonary function test results. The FET values in different groups were compared. The side effects in the 3 groups and the diagnostic accuracy, specificity and security of different FET in the obstructive group were assessed. Results: The FET values of the normal group, the obstructive group, and the restricted group were (4.00±1.07) s, (8.08±1.56) s and (2.97±0.76) s respectively, and the 95% CI of FET in the 3 groups were between 3.88-4.12 s, 7.02-10.14 and 2.21- 3.73 s (F=2 263.80, P<0.01). When the exhalation platform was used as the standard of FVC curve, the adverse reaction rate in the normal group and the restricted group were 1.1% and 1.3% respectively, lower than the rate of 17.2% in the obstructive group (χ(2)=92.73, χ(2)=48.49 respectively; all P<0.05). In the obstructive group, 7 s as the ending criterion had similar incidence of adverse reactions to 6 s (χ(2)=0.01, P=0.93). With further extension of expiration time, the incidence of adverse reactions increased significantly. In the obstructive group, the sensitivity of FEV(1)/FEV(7) was 99.25%, higher than that at FEV(1)/FEV(6) (χ(2)=4.06, P=0.04), and the specificity of diagnosis was very similar and 100%. Conclusions: FET was variable in subjects with different lung function status. It is not appropriate to use a fixed FET≥ 6 s as the end criterion of spirometry for adults. For patients with normal lung function or restrictive lung function defect, exhalation platform should be used as the end of exhalation standard. For patients with obstructive lung function defect, an FET of up to 7 s is appropriate.

Abstract
To explore the relationship between the community of epilithic algae and environmental factors in tributaries of the Three Gorges Reservoir region, the epilithic algae and related environment factors were investigated from 26 sampling sites in Meixi River, a tributary of the Three Gorges Reservoir region, during flood period (August 2016), drought period (November 2016), and normal water period (March 2017). Results showed that 106 species (including varieties) belonging to 47 genera and 5 families were identified from 26 sampling sites during the three periods. Among these, 73 species belonged to 38 genera and 5 families in the flood period, 67 species belonged to 36 genera and 4 families in the drought period, and 63 species belonged to 33 genera and 4 families in the normal water period. Nineteen, 17, and 18 dominant species were identified during the flood period, drought period, and normal water period, respectively. The main dominant species were Achnanthes sp., Aphanizomenon sp., and Phormidium sp. in the flood period; Achnanthes sp., Gomphonema sp., and Microcystis sp. in the drought period; and Gomphonema sp., Nitzschia sp., and Chroococcus sp. in the normal water period. Moreover, species such as Cocconeis placentula, Achnanthes sp., Gomphonema subclavatum, G. parvulum, Navicula parva, and G. constrictum were determined to be the common dominant species during the three periods. Redundancy analysis revealed that the changes in the relative abundance of dominant species in the backwater sections were significantly related to the electrical conductivity, dissolved oxygen, pH, total phosphorus, and total nitrogen, and the relative abundance of dominant species in the natural sections was mainly related to the electrical conductivity, pH, total phosphorus, temperature, and velocity. Moreover, a different relationship with the environmental factors was determined among the three periods. However, a negative correlation between total phosphorus and the relative abundances in G. parvulum, G. constrictum, and Achnanthes sp. and a positive correlation between pH and the relative abundances in G. parvulum, G. constrictum, and Achnanthes sp. were found during the three periods. These results indicated that the differences in the hydrological regime and environmental factors in the Three Gorges Reservoir played an important role on the composition of epilithic algae community and led to a significant change in the community structure of epilithic algae.
