Abstract
Two previously undescribed cholestanol saponins, parpetiosides F - G (1-2), and six known analogs (3-8) were isolated from the rhizomes of Paris fargesii var. petiolata. Their structures were elucidated by extensive spectroscopic data analysis and chemical methods. Compound 1 was a rare 6/6/6/5/5 fused-rings cholestanol saponin with disaccharide moiety linked at C-26 of aglycone which was hardly seen in genus Paris. All of these compounds were discovered in this plant for the first time. In addition, the cytotoxicities of saponins (1-8) against three human cancer cell lines (U87, HepG2 and SGC-7901) were evaluated by CCK-8 method, and saponins 5-8 displayed certain cytotoxicities. The strong interactions between saponins 5-8 and SCUBE3, an oncogene for glioma cells, were displayed by molecular docking.

Abstract
Primary alkyl amines are highly reactive in N-nucleophilic reactions with electrophiles. However, their α-C-H bonds are unreactive towards electrophiles due to their extremely low acidity (pKa ~57). Nonetheless, 1,8-diazafluoren-9-one (DFO) can activate primary alkyl amines by increasing the acidity of the α-amino C-H bonds by up to 1044 times. This makes the α-amino C-H bonds acidic enough to be deprotonated under mild conditions. By combining DFO with an iridium catalyst, direct asymmetric α-C-H alkylation of NH2-unprotected primary alkyl amines with allylic carbonates has been achieved. This reaction produces a wide range of chiral homoallylic amines with high enantiopurities. The approach has successfully switched the reactivity between primary alkyl amines and allylic carbonates from intrinsic allylic amination to the α-C-H alkylation, enabling the construction of pharmaceutically significant chiral homoallylic amines from readily available primary alkyl amines in a single step.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zanthoxylum bungeanum Maxim. (Rutaceae) is a known herbal medicine with various bioactivities, including anti-obesity, lipid-lowering, learning & memory improving and anti-diabetes, and amides in Z. bungeanum (AZB) are considered as the major active agents for its bioactivities. AIM OF THE STUDY This research was carried out to uncover the anti-NAFL effect of AZB and its corresponding molecular mechanisms. METHODS The central composite design-response surface methodology (CCD-RSM) was utilized to optimize the AZB extraction process, and the anti-NAFL effect of AZB was investigated on high fat diet (HFD) fed mice (HFD mice). The levels of ROS in liver tissues were determined using laser confocal microscopy with DCFH-DA probe staining, and anti-enzymes (such as HO-1, SOD, CAT & GSH-PX) and MDA in liver tissues were measured using commercial detecting kits. GC-MS was used to determine the short-chain fatty acids (SCFAs) contents in feces and blood of mice. 16S high-throughput sequencing, western blotting (WB) assay and immunofluorescence (IF) were used to explore the intestinal flora changes in mice and the potential mechanisms of AZB for treatment of NAFL. RESULTS Our results showed AZB reduced body weight, alleviated liver pathological changes, reduced fat accumulation, and improved oxidative stress in HFD mice. In addition, we also found AZB improved OGTT and ITT, reduced TG, TC, LDL-C, whereas increased HDL-C in HFD mice. AZB increased total number of the species and interspecies kinship of gut microbiota and reduced the richness and diversity of gut microbiota in HFD mice. Moreover, AZB decreased the ratio of Firmicutes/Bacteroidota, whereas increased the abundance of Allobaculum, Bacteroides and Dubosiella in feces of HFD-fed mice. Furthermore, AZB increased the production of SCFAs, and up-regulated the phosphorylation of AMPK and increased the nuclear transcription of Nrf2 in liver of HFD mice. CONCLUSION Collectively, our results suggested AZB can improve NAFL, which could reduce body weight, reverse liver lesions and fat accumulation, improve oxidative stress in liver tissues of HFD mice. Furthermore, the mechanisms are related to increase of the abundance of high-producing bacteria for SCFAs (e.g. Allobaculum, Bacteroides and Dubosiella) to activate AMPK/Nrf2 signaling.

Abstract
BACKGROUND Accumulating evidence suggested increasing energy expenditure is a feasible strategy for combating obesity, and browning of white adipose tissue (WAT) to promote thermogenesis might be one of the attractive ways. Hydroxy-α-sanshool (HAS), a natural amide alkaloid extracted from the fruits of Zanthoxylum bungeanum Maxim, possesses lots of benefits in lipid metabolism regulation. METHODS The anti-obesity effect of HAS was investigated by establishing an animal model of obesity and a 3T3-L1 differentiation cell model. Effects of HAS on the whole-body fat and liver of obese mice, and the role of HAS in inducing browning of white fat were studied by Micro CT, Metabolic cage detection, Cell mitochondrial pressure detection, transmission electron microscopy and cold exposure assays. Furthermore, the Real-time PCR (qPCR), digital PCR (dPCR), western blot, Co-immunoprecipitation (Co-IP), molecular docking, drug affinity responsive target stability (DARTS), Cellular thermal shift assay (CETSA) and other methods were used to investigate the target and mechanisms of HAS. RESULTS We found that treatment with HAS helped mice combat obesity caused by a high fat diet (HFD) and improve metabolic characteristics. In addition, our results suggested that the anti-obesity effect of HAS is related to increase energy consumption and thermogenesis via induction of browning of WAT. The further investigations uncovered that HAS can up-regulate UCP-1 expression, increase mitochondria number, and elevate the cellular oxygen consumption rates (OCRs) of white adipocytes. Importantly, the results indicated that browning effects of HAS is closely associated with SIRT1-dependent PPAR-γ deacetylation through activating the TRPV1/AMPK pathway, and TRPV1 is the potential drug target of HAS for the browning effects of WAT. CONCLUSIONS Our results suggested the HAS can promote browning of WAT via regulating AMPK/SIRT-1/PPARγ signaling, and the potential drug target of HAS is the membrane receptor of TRPV1.

Abstract
This study investigated the impact of subway car interior design on passenger evacuation and boarding/alighting efficiency. The usability of pedestrian agent models was verified through real-life experiments. A seven-factor orthogonal simulation experiment was designed, using key geometric features of the subway car interior as variables. The results of the computer simulation showed that the impact of subway car interior design factors on evacuation and boarding/alighting time was not entirely consistent, with seat layout and door width being the most important factors affecting passenger movement. In the evacuation scenario, only the connectivity of the subway car has no effect on evacuation time, while in the boarding and alighting scenario, seat layout, car type, door width, and foyer width all significantly affect boarding and alighting time. Multivariate regression models were established to predict evacuation and boarding/alighting times through design features, which can explain 86.7% and 58.9% of the time variation, respectively. The research results were used to guide subway car design, and the proposed new scheme demonstrated better performance.

Abstract
Background Metabolic syndrome is characterized by a cluster-like occurrence of conditions such as hypertension, hyperglycaemia, elevated low-density lipoprotein (LDL) cholesterol or triglycerides (TG) and high visceral fat. Metabolic syndrome is linked to the build-up of plaque within the artery, which leads to disorders of the circulatory, nervous and immune systems. A variety of treatments target the regulation of these conditions; nevertheless, they remain dominant risk factors for the development of type 2 diabetes (T2DM) and cardiovascular disease (CVD), which affect 26.9% of the US population. Management and intervention strategies for improving cholesterol and/or TG are worthwhile, and recent studies on hydrogen treatment are promising, particularly as molecular hydrogen is easily ingested. This study aimed to investigate the lipid-lowering effects and quality of life (QOL) improvement of hydrogen-rich coral calcium (HRCC) in patients with metabolic syndrome. Methods The patients, all Taiwanese, were randomly assigned to 3 different doses (low, medium, and high) of HRCC capsules. The primary outcome was the adverse effects/symptoms during this 4-week use of HRCC capsules. The secondary outcome was lipid profile changes. Complete blood count, inflammatory biomarkers, and QOL were also measured before and after the course of HRCC. Results Sixteen patients with metabolic syndrome completed this study (7 males, 9 females; mean age: 62 years; range: 32-80). No obvious adverse effects were recorded. Only changes in blood TG reached significance. The baseline TG value was 193.19 μL (SD = 107.44), which decreased to 151.75 μL (SD = 45.27) after 4 weeks of HRCC (p = 0.04). QOL showed no significant changes. Conclusion This study is the first human clinical trial evaluating HRCC capsules in patients with metabolic syndrome. Based on the safety and potential TG-lowering effects of short-term HRCC, further long-term investigations of HRCC are warranted. Clinical trial registration [ClinicalTrials.gov], identifier [NCT05196295].

Abstract
Current clinical approaches for septic shock increasingly incorporate bundle treatment, a multi-component approach that uses a collection of tests and agents to assist in the identification and treatment of infection. The present study analyzed completion rates of 3 h and 6 h bundle treatment among patients with septic shock in intensive care units (ICUs) of hospitals in Jiangsu Province from 2016 to 2020, using data from the Jiangsu Provincial Intensive Care Medical Quality Control Center. Current approaches and factors affecting treatment completion were assessed.The completion rates of 3 h and 6 h bundle treatment in ICUs of all medical units in Jiangsu Province and in ICUs of hospitals of different levels were recorded. Analyses show that the completion rate of 3 h and 6 h bundle treatment for patients with septic shock in ICUs in Jiangsu Province increased year by year from 2016 to 2020.The completion rate of 3 h bundle treatment increased from 69.82% (3 604/5 162) to 82.47% (8 915/10 775) (all P<0.001). The completion rate of 6 h bundle treatment increased from 62.69% (3 236/5 162) to 72.54% (7 816/10 775) (all P<0.001). In addition, year by year, the completion rate of 3 h bundle treatment in ICUs in tertiary hospitals increased, from 69.80% (3 596/5 152) to 82.23% (7 375/8 969), while the completion rate of 6 h bundle treatment increased from 62.69% (3 230/5 152) to 72.18% (6 474/8 969) (all P<0.001). Completion rates in secondary hospitals also increased year by year, from 80.00% (8/10) to 85.27% (1 540/1 806) for 3 h treatment and from 60.00% (6/10) to 74.31% (1 342/1 806) (all P<0.001) for 6 h treatment. Completion rates for 3 h treatment in first-tier cities (83.99% (2 099/2 499)) and second-tier cities (84.68% (3 952/4 667)) was higher than in third-tier cities (79.36% (2 864/3 609)). The completion rate of 6 h bundle treatment gradually decreased in first-line (77.19% (1 929/2 499)), second-line (74.37% (3 471/4 667)), and third-line (66.94% (2 416/3 609)) cities (all P<0.001). The data collectively show that from 2016 to 2020, the completion rate of bundle treatment in septic shock patients in ICUs in Jiangsu Province improved significantly.

Abstract
A phytochemical investigation of the steroidal saponins from the rhizomes of Paris polyohylla var. latifolia led to the discovery and characterization of three new spirostanol saponins, papolatiosides A-C (1-3), and nine known compounds (4-12). Their structures were established via extensive spectroscopic data analysis and chemical methods. Interestingly, compounds 1 and 2 possessed a fructosyl in their oligosaccharide moiety, which is rare in natural product and was firstly reported in family Melanthiaceae. The cytotoxicity of these saponins against several human cancer cell lines was evaluated by a CCK-8 experiment. As a result, compound 1 exhibited a significant cytotoxic effect on LN229, U251, Capan-2, HeLa, and HepG2 cancer cells with IC50 values of 4.18 ± 0.31, 3.85 ± 0.44, 3.26 ± 0.34, 3.30 ± 0.38 and 4.32 ± 0.51 μM, respectively. In addition, the result of flow cytometry analysis indicated that compound 1 could induce apoptosis of glioma cells LN229. The underlying mechanism was explored by network pharmacology and western bolt experiments, which indicated that compound 1 could induce glioma cells LN229 apoptosis by regulating the EGFR/PI3K/Akt/mTOR pathway.

Abstract
BACKGROUND Icaritin is an aglycone of flavonoid glycosides from Herba Epimedii. It has good performance in the treatment of hepatocellular carcinoma in clinical trials. However, the natural icaritin content of Herba Epimedii is very low. At present, the icaritin is mainly prepared from flavonoid glycosides by α-L-rhamnosidases and β-glucosidases in two-step catalysis process. However, one-pot icaritin production required reported enzymes to be immobilized or bifunctional enzymes to hydrolyze substrate with long reaction time, which caused complicated operations and high costs. To improve the production efficiency and reduce costs, we explored α-L-rhamnosidase SPRHA2 and β-glucosidase PBGL to directly hydrolyze icariin to icaritin in one-pot, and developed the whole-cell catalytic method for efficient icaritin production. RESULTS The SPRHA2 and PBGL were expressed in Escherichia coli, respectively. One-pot production of icaritin was achieved by co-catalysis of SPRHA2 and PBGL. Moreover, whole-cell catalysis was developed for icariin hydrolysis. The mixture of SPRHA2 cells and PBGL cells transformed 200 g/L icariin into 103.69 g/L icaritin (yield 95.23%) in 4 h in whole-cell catalysis under the optimized reaction conditions. In order to further increase the production efficiency and simplify operations, we also constructed recombinant E. coli strains that co-expressed SPRHA2 and PBGL. Crude icariin extracts were also efficiently hydrolyzed by the whole-cell catalytic system. CONCLUSIONS Compared to previous reports on icaritin production, in this study, whole-cell catalysis showed higher production efficiency of icaritin. This study provides promising approach for industrial production of icaritin in the future.

Abstract
Objective: To analyze the status of excess heart age and its risk factors among Chinese residents aged 35 to 64 years. Methods: The study subjects were Chinese residents aged 35 to 64 years who completed the heart age assessment by WeChat official account"Heart Strengthening Action"through the internet from January 2018 to April 2021. Information such as age, gender, body mass index (BMI), blood pressure, total cholesterol (TC), smoking history, and diabetes history was collected. The heart age and excess heart age were calculated according to the characteristics of individual cardiovascular risk factors and the heart aging was defined as excess heart age≥5 years and 10 years respectively. The heart age and standardization rate were calculated respectively based on the population standardization of the 7th census in 2021.CA trend test was used to analyze the changing trend of excess heart age rate and population attributable risk (PAR) was used to calculate the contribution of risk factors. Results: The mean age of 429 047 subjects was 49.25±8.66 years. The male accounted for 51.17% (219 558/429 047) and the excess heart age was 7.00 (0.00, 11.00) years. The excess heart age rate defined by excess heart age≥5 years and≥10 years was 57.02% (the standardized rate was 56.83%) and 38.02% (the standardized rate was 37.88%) respectively. With the increase of the age and number of risk factors, the excess heart age rate of the two definitions showed an upward trend according to the result of the trend test analysis (P<0.001). The top two risk factors of the PAR for excess heart age were overweight or obese and smoking. Among them, the male was smoking and overweight or obese, while the female was overweight or obese and having hypercholesterolemia. Conclusion: The excess heart age rate is high in Chinese residents aged 35 to 64 years and the contribution of overweight or obese, smoking and having hypercholesterolemia ranks high.

Abstract
BACKGROUND Controversy has persisted over the clinical benefits of low-dose sacubitril/valsartan in patients with heart failure (HF). HYPOTHESIS Low-dose sacubitril/valsartan might also be effective and safe in HF patients. METHODS Electronic databases including PubMed, Ovid, and Cochrane Library were systematically retrieved from inception to August 5, 2021. Review manager 5.4 and Stata 15.1 were employed in this systematic review and meta-analysis. Key efficacy outcomes of interest included HF hospitalization, all-cause mortality, left ventricular ejection fraction (LVEF), N-terminal pro-B-type natriuretic peptide (NT-proBNP), together with New York Heart Association (NYHA) functional class. The safety outcome was systolic blood pressure (SBP). The grading of recommendations assessment, development, and evaluation approach was conducted to evaluate the quality of evidence for each outcome. RESULTS A total of 1269 studies were screened and 9 real-world studies met the inclusion criteria were included in the meta-analysis, with 1697 participants. Compared with low-dose sacubitril/valsartan, high-dose sacubitril/valsartan significantly reduced the risk of HF hospitalization (odds ratio [OR]: 0.4, 95% confidence interval [CI]: 0.27-0.61, p < .0001) and the risk of all-cause mortality (OR: 0.23, 95% CI: 0.11-0.47, p < .0001). However, there were no appreciable differences in improvements of NYHA (OR: 0.59, 95% CI: 0.15-2.35, p = .45), changes of LVEF (mean difference [MD]: 2.73%, 95% CI: -2.24% to 7.7%, p = .28), changes of NT-proBNP (MD: 43.09, 95% CI: -28.41 to 114.59, p = .24) and changes of SBP (MD: 3.01, 95% CI: -4.62 to 10.64, p = .44) between groups with low-dose and high-dose sacubitril/valsartan. CONCLUSIONS Compared with high-dose sacubitril/valsartan, low-dose sacubitril/valsartan was associated with increased risks of HF hospitalization and all-cause mortality. However, no distinct between-group differences in improvements of NYHA, changes of LVEF, changes of NT-proBNP and changes of SBP were observed.

Abstract
Phytochemical investigation on the rhizomes of Paris fargesii var. petiolata (Baker ex C. H. Wright) Wang et Tang led to the isolation of five previously undescribed steroidal saponins, parpetiosides A-E (1-5), and six known analogs (6-11). Their structures were established by extensive spectroscopic data analysis and chemical methods. Compound 5 was a rare steroidal saponin with disaccharide moiety linked at C-26 of dehydrokryptogenin that was hardly seen in the genus Paris. The cytotoxicities of the isolated compounds against three human cancer cell lines (U87, HepG2 and SGC-7901) were evaluated, and compound 1 displayed certain inhibitory effect with IC50 values of 8.02 ± 0.45, 8.24 ± 0.57 and 6.20 ± 0.79 μM, respectively. Moreover, the preliminary mechanism of 1 inhibiting the proliferation of the three cancer cell lines might be related to cell cycle distribution and the induction of S phase arrest.

Abstract
Purpose Development and evaluation of a drug-safety signal detection system integrating data-mining tools in longitudinal data is essential. This study aimed to construct a new triage system using longitudinal data for drug-safety signal detection, integrating data-mining tools, and evaluate adaptability of such system. Patients and Methods Based on relevant guidelines and structural frameworks in Taiwan's pharmacovigilance system, we constructed a triage system integrating sequence symmetry analysis (SSA) and tree-based scan statistics (TreeScan) as data-mining tools for detecting safety signals. We conducted an exploratory analysis utilizing Taiwan's National Health Insurance Database and selecting two drug classes (sodium-glucose co-transporter-2 inhibitors (SGLT2i) and non-fluorinated quinolones (NFQ)) as chronic and episodic treatment respectively, as examples to test feasibility of the system. Results Under the proposed system, either cohort-based or self-controlled mining with SSA and TreeScan was selected, based on whether the screened drug had an appropriate comparator. All detected alerts were further classified as known adverse drug reactions (ADRs), events related to other causes or potential signals from the triage algorithm, building on existing drug labels and clinical judgement. Exploratory analysis revealed greater numbers of signals for NFQ with a relatively low proportion of known ADRs; most were related to indication, patient characteristics or bias. No safety signals were found. By contrast, most SGLT2i signals were known ADRs or events related to patient characteristics. Four were potential signals warranting further investigation. Conclusion The proposed system facilitated active and systematic screening to detect and classify potential safety signals. Countries with real-world longitudinal data could adopt it to streamline drug-safety surveillance.

Abstract
BACKGROUND Mediation is increasingly used for medical dispute resolution, and the particularity of such mediation necessitates specialized training. In response to the promotion of compulsory mediation ahead of a legislation in Taiwan, we invited experts with an interdisciplinary team to design a case-based mediator training workshop. Our study aimed to investigate the learning outcomes of trainees and analyze their perspectives. METHODS We recruited 129 trainees of a non-probability convenience sample who served as mediators or have dealt with medical dispute-related cases to undergo 2.5 h of lectures (introduction; procedure; roles of two mediators; principles and techniques of mediation; dispute arrangement; and issue analysis) and 1.5 h of case-based exercises. An after-class survey was conducted using a 4-point Likert-type scale to evaluate trainees' viewpoints and learning outcomes. A total of 104 questionnaires were collected (response rate: 80.6%). RESULTS The professions of the participants were medical (56%), law (16%), and administration and others (28%). Males considered the course more helpful (3.79 vs. 3.63, p = 0.053) and more important (3.88 vs. 3.74, p = 0.042) than did females. Participants with a legal background scored the highest in helpfulness (3.84), followed by medical (3.74) and administrative (3.63) professionals. Medical and administrative professionals scored the highest (3.85) and lowest (3.76), respectively, on importance. Respondents with more than 10 years (3.81) and less than 1 year (3.79) of experience produced higher scores in helpfulness. Respondents with 1-5 years of experience (3.68) were found to be less likely to agree with the practical importance of course content compared with other groups of trainees. Administrative professionals obtained the highest scores (89.68) in written examinations. CONCLUSIONS There are variations in mediators' perspectives based on gender, occupation, and work experience. Our nationwide mediation training workshop can be utilized to cultivate capabilities of mediators for handling medical disputes to achieve the goal of non-litigation in medical disputes.

Abstract
OBJECTIVES To establish a training programme to cultivate trainee mediation skills through time investment, skill incorporation and formation of in-house mediation services. DESIGN A four-round consensus conference was conducted by a number of seasoned experts selected in the manner of purposive sampling to determine core competences and relevant curricula through the modified Delphi process. SETTING Responses collected from enrolled experts through four rounds of the Delphi process from 11 November 2018 to 17 May 2019. PARTICIPANTS Onboard seasoned mediators with different specialties. OUTCOME MEASURES Items with a median rating of 4 or more on a Likert scale of 1-7 points and 70% or more in agreement were identified as core competence and curricula. RESULTS Eleven enrolled experts reached the consensus about the training syllabus based on the 4-round agreement with four pillars of core competence, including 'knowledge base of law', 'internalisation of the denotative and connotative meanings of care', 'effective, smooth and timely communication' and 'conflict resolution'. To grasp the dynamics and diversity of medical disputes on target, it is necessary to have sufficient knowledge and skills. We arrange our course in the order of teaching materials with pure didactics in the former two and with mixed contents comprising lectures and field exercises in the rest two. CONCLUSIONS The sample developed a syllabus to train apprentices to take intermediate responses to medical disputes through the skills of conflict resolution and establishment of effective communication to improve the relationship between patients/relatives and medical staff, as a result of eventually reducing the conversion rate from dispute into litigation or alternative pathway. Policy-makers in healthcare and top management in healthcare institutions can use this syllabus to guide their future education and training programme.

Abstract
Objective: To analyzed perioperative safety of cytoreductive surgery (CRS) for patients with colorectal cancer peritoneal metastasis (CRPM) and to construct a predictive model for serious advese events (SAE). Methods: A descriptive case-series study was conducted to retrospectively collect the clinicopathological data and treatment status (operation time, number of organ resection, number of peritoneal resection, and blood loss, etc.) of 100 patients with peritoneal metastases from colorectal cancer or appendix mucinous adenocarcinoma who underwent CRS at the Sixth Affiliated Hospital of Sun Yat-sen University from January 2019 to August 2021. There were 53 males and 47 females. The median age was 52.0 (39.0-61.8) years old. Fifty-two patients had synchronous peritoneal metastasis and 48 had metachronous peritoneal metastasis. Fifty-two patients received preoperative neoadjuvant therapy. Primary tumor was located in the left colon, the right colon and the rectum in 43, 28 and 14 cases, respectively. Fifteen patients had appendix mucinous adenocarcinoma. Measures of skewed distribution are expressed as M (range). Perioperative safety was analyzed, perioperative grade III or higher was defined as SAE. Risk factors associated with the occurrence of SAEs were analyzed using multivariate logistic regression. A nomogram was plotted by R software to predict SAE, the efficacy of which was evaluated using the area under the ROC curve (AUC) and correction curves. Results: The median peritoneal cancer index (PCI) score was 16 (1-39). Sixty-eight (68.0%) patients achieved complete tumor reduction (tumor reduction score: 0-1). Sixty-two patients were treated with intraperitoneal hyperthermic perfusion chemotherapy (HIPEC). Twenty-one (21.0%) patients developed 37 SAEs of grade III-IV, including 2 cases of ureteral injury, 6 cases of perioperative massive hemorrhage or anemia, 7 cases of digestive system, 15 cases of respiratory system, 4 cases of cardiovascular system, 1 case of skin incision dehiscence, and 2 cases of abdominal infection. No grade V SAE was found. Multivariate logistic regression analysis showed that CEA (OR: 8.980, 95%CI: 1.428-56.457, P=0.019), PCI score (OR: 7.924, 95%CI: 1.486-42.259, P=0.015), intraoperative albumin infusion (OR: 48.959, 95%CI: 2.115-1133.289, P=0.015) and total volume of infusion (OR: 24.729, 95%CI: 3.956-154.562, P=0.001) were independent risk factors for perioperative SAE in CRS (all P<0.05). Based on the result of multivariate regression models, a predictive nomogram was constructed. Internal verification showed that the AUC of the nomogram was 0.926 (95%CI: 0.872-0.980), indicating good prediction accuracy and consistency. Conclusions: CRS is a safe and effective method to treat CRPM. Strict screening of patients and perioperative fluid management are important guarantees for reducing the morbidity of SAE.

Abstract
Owing to the strong nucleophilicity of the NH2 group, free-NH2 glycinates react with MBH acetates to usually deliver N-allylated products even in the absence of catalysts. Without protection of the NH2 group, chiral pyridoxal catalysts bearing an amide side chain at the C3 position of the naphthyl ring switched the chemoselectivity of the glycinates from intrinsic N-allylation to α-C allylation. The reaction formed chiral multisubstituted glutamic acid esters as SN 2'-SN 2' products in good yields with excellent stereoselectivity (up to 86 % yield, >20 : 1 dr, 97 % ee). As compared to pyridoxal catalysts bearing an amide side arm at the C2 position, the pyridoxals in this study have a bigger catalytic cavity to enable effective activation of larger electrophiles, such as MBH acetates and related intermediates. The reaction is proposed to proceed via a cooperative bifunctional catalysis pathway, which accounts for the high level of diastereo- and enantiocontrol of the pyridoxal catalysts.

Abstract
BACKGROUND Whether hepatitis B virus (HBV) infection can affect the outcomes of drug-induced liver injury (DILI) is controversial. This study aimed to evaluate the characteristics and outcomes of DILI in Taiwan, with an emphasis on the impact of HBV infection. METHODS We prospectively recruited patients with DILI from multiple centers in Taiwan from 2010 to 2018. RESULTS A total of 1,014 patients were enrolled. The leading culprit drug category was antimicrobials (481, 47.4%), followed by nonsteroidal anti-inflammatory drugs, anticonvulsants, and statins. Among the antimicrobials, antituberculosis agents were most likely to induce liver injury (257, 25.3%), followed by antibacterial, antifungal, and antiviral agents. The liver-related mortality rate was 8.2% (83/1,014). The patients who died had higher rates of hepatocellular-type liver injury, elevated liver biochemical tests, preexisting liver cirrhosis, jaundice, chronic HBV infection, and antituberculosis drug-induced liver injury (ATDILI) than the survivors. A total of 131 patients (12.9%) with DILI were HBV carriers, of whom 23 (17.6%) died of hepatic failure. The rate of HBV-DNA > 2000 IU/mL was higher in the patients who died (47.8% vs. 26.9%, p = 0.047) than in the survivors. After adjusting for possible risk factors, active HBV infection with HBV-DNA > 2000 IU/mL was the most significant risk factor for liver-related mortality (adjusted HR, 4.40, 95% CI, 2.31%-8.38%, p < 0.001). The other independent risk factors for mortality were ATDILI and albumin-bilirubin (ALBI) score (adjusted HR, 1.25 and 4.09, respectively, p < 0.003). CONCLUSION Antituberculosis agents were the leading cause of DILI in Taiwanese, and they were associated with poorer outcomes than other drug categories. Active HBV infection, ATDILI and ALBI score were independent risk factors for fatal DILI. Close monitoring of liver tests and timely antiviral therapy should be implemented in HBV carriers during the administration of high-risk drugs, such as antituberculosis agents.

Abstract
A new type of chiral super Brønsted C-H acids, BINOL-derived phosphoryl bis((trifluoromethyl)sulfonyl) methanes (BPTMs), were developed. As compared to widely utilized BINOL-derived chiral phosphoric acids (BPAs) and N-triflyl phosphoramides (NTPAs), BPTMs displayed much higher Brønsted acidity, resulting in dramatically improved activity and excellent enantioselectivity as demonstrated in catalytic asymmetric Mukaiyama-Mannich reaction, allylic amination, three-component coupling of allyltrimethylsilane with 9-fluorenylmethyl carbamate and aldehydes, and protonation of silyl enol ether. These new strong Brønsted C-H acids have provided a platform for expanding the chemistry of asymmetric Brønsted acid catalysis.

Abstract
PURPOSE Free triiodothyronine (FT3) and FT3/free thyroxine (FT4) ratio have been associated with mortality in various diseases. However, no study to date has identified a link between FT3, FT3/FT4 ratio and all-cause mortality in patients with diabetic foot ulcers (DFUs). This study aimed to investigate this relationship. METHODS This retrospective cohort study included 726 patients diagnosed with DFUs in a public hospital from January 2015 to October 2019. Patients were classified by the optimal cut-off values of the FT3 and FT3/FT4 ratio, respectively. The association of FT3 and FT3/FT4 ratio with all-cause mortality was evaluated in a multivariable cox regression model. Directed acyclic graphs were used to assess the minimally sufficient sets of confounding variables. RESULTS Log rank tests indicated that patients with low FT3 and FT3/FT4 ratio had lower overall survival rates (all p < 0.001). The adjusted HRs for all-cause mortality were 0.48 (95% CI: 0.32-0.73, P = 0.001) when comparing high versus low FT3 and 0.47 (95% CI: 0.32-0.70, P < 0.001) when comparing high versus low FT3/FT4 ratio. Subgroup analyses showed that these associations existed only in elderly patients (≥65 years) and women, after adjustment. In men, only high FT3/FT4 ratio was associated with low all-cause mortality, after adjustment. CONCLUSION Routine assessment of FT3 and FT3/FT4 ratio may be a simple and effective way to identify high-risk patients with DFUs, especially in elderly patients and women.

Abstract
PURPOSE The magnetic compression technique (MCT) is a new surgical method that has been used for gastrointestinal anastomosis, choledochojejunostomy, and intestinal anastomosis, but there are no reports on its use for esophagogastric anastomosis. This study aimed to investigate the feasibility of using MCT to fashion esophagogastric anastomoses in rabbits. METHODS Twenty rabbits were randomized into an MCT group (study group, n = 10) and a hand-sewn group (control group, n = 10). The magnetic compression anastomosis device used in this study was made of neodymium iron boron (NdFeB) and possessed parent (PMR) and daughter (DMR) magnetic rings. To fashion the anastomosis, the PMR and DMR were inserted into the lower esophagus and gastric fundus, respectively. The coupled magnets automatically compressed the sandwiched tissues and were expelled once the anastomosis was installed. The two groups were further compared in terms of the anastomosis construction time, survival rate, and postoperative complications. One month after the anastomosis was installed, the burst pressure and gross appearance of the anastomoses were evaluated. RESULTS The anastomosis construction time in the study group was significantly shorter than that in the control group (10.50 ± 1.58 min vs. 18.60 ± 2.22 min; P < 0.05), and the magnetic rings were defecated out in 10.70 ± 3.49 days. The incidence of anastomotic blockage in both the study and control groups did not differ significantly (0%, 0/10 vs. 20%, 2/10; P > 0.05). Anastomotic leakage was not found in either of the groups, and the anastomoses burst pressures were similar in the two groups. However, the magnetically compressed anastomoses in the study group had a relatively smoother gross appearance than the hand-sewn anastomoses. CONCLUSION The magnetic compression anastomosis device is a safe and feasible tool for fashioning esophagogastric anastomoses in this animal model.

Abstract
To investigate associations between isoniazid for latent tuberculosis and risk of severe hepatitis, affecting patients with rheumatoid arthritis or ankylosing spondylitis whose treatment includes tumor necrosis factor inhibitors. Our self-controlled case series study analyzed Taiwan’s National Health Insurance Database from 2003 to 2015 to identify RA or AS patients, aged ≥ 20 years, receiving TNF inhibitors and a 9-month single isoniazid treatment. The outcome of interest was hospitalization due to severe hepatitis. We defined risk periods by isoniazid exposure (days): 1–28, 29–56, 57–84, 85–168, 169–252, and 253–280. To compare risk of severe hepatitis in exposed and non-exposed periods, we performed conditional Poisson regressions to generate incidence rate ratios (IRR) and 95% confidence intervals, with adjustment of patients’ baseline covariates including age, sex, HBV, HCV and related medication. Of 54,267 RA patients and 137,889 AS patients identified between 2000 and 2015, 11,221 (20.7%) RA and 4,208 (3.1%) AS patients underwent TNFi therapy, with 722 (5%) receiving isoniazid for latent tuberculosis. We identified 31 incident cases (4.3%) of hospitalization due to severe hepatitis. Of these hospitalization events, 5 occurred in the exposed periods, 25 occurred in the INH unexposed periods, and 1 occurred in the pre-exposure period. Compared with non-exposure, the risk of severe hepatitis was higher in exposed periods (incidence rate ratio [IRR]: 5.1, 95% CI: 1.57–16.55), especially 57–84 days (IRR: 17.29, 95% CI: 3.11–96.25) and 85–168 days (IRR:10.55, 95% CI: 1.90–58.51). The INH related fatal hepatotoxicity was not identified in our study. Our findings suggest an association between risk of severe hepatitis and exposure to isoniazid in patients with RA or AS under TNFi therapy, particularly within the exposed period 57–168 days. A close monitoring of liver function is mandatory to minimize the risk, especially within the first 6 months after initiation of 9 months isoniazid.

Abstract
Objective: To explore whether the cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS+HIPEC) can improve the survival rate of colorectal cancer patients with peritoneal metastasis. Methods: The relevant studies were systematically retrieved from PubMed, Embase, Cochrane Library, CNKI, Wanfang, VIP database, and the study of French Elias' team on peritoneal metastasis was retrieved manually. Inclusion criteria: (1) The patients were colorectal cancer peritoneal metastasis. (2) There were CRS+HIPEC treatments (treatment group) and other treatments (control group). (3) Survival analysis data of treatment group and control group were available. (4) Types of studies were randomized controlled trials, cohort studies, or case-control studies. (5) The literature was in Chinese or English. Exclusion criteria: (1) studies without full-text; (2) studies without complete data. The literature screening and data extraction were carried out by two people independently, and the third person decided on the literature with differences. The extracted data included authors, year of publication, number of patients, time of enrollment, time of follow-up, studies design, treatment regimen, hazard ratio (HR) and 95% CI of treatment group and control groups. If the HR and 95% CI of the treatment group and control group were not provided in the literature, Engauge Digitizer 11.1 software was used to extract the time of follow-up and the survival rate at the corresponding time point from the survival curves of both groups, and the HR and 95% CI of both groups were calculated by combining the number of both groups. The quality of study was evaluated by Newcastle-Ottawa scale (NOS) or Cochrane collaboration's tool for assessing risk bias. STATA 15.1 software was used for statistical analysis. HR and 95% CI of both groups were pooled and analyzed. Inter-trial heterogeneity was assessed by Q test and I(2) statistics. When there was no significant heterogeneity (Q test: P≥0.10), fixed-effect model was used for pooled analysis. When significant heterogeneity existed (Q test: P<0.10), random effect model was used for pooled analysis, and subgroup analysis was used to find out the source of heterogeneity. Sensitivity analysis was used to evaluate the stability of the pooled results. Publication bias was assessed by Egger's test and Begg's test (P<0.05 indicated publication bias) and it is reflected by the visual symmetry of Begg's funnel plot on the natural logarithm of HR. Results: A total of 10 studies were enrolled in the meta-analysis, including 1 randomized controlled trial and 9 cohort studies. The risk of bias in 1 randomized controlled trial was uncertain, and 9 cohort studies were all higher than 7 points, indicating high quality literatures. There were 781 patients in treatment group receiving CRS+HIPEC and 2452 patients in control group receiving other treatment, including tumor cytoreductive surgery (CRS), palliative chemotherapy (PC) and intraperitoneal chemotherapy (IPC). The results of pooled analysis by random effect model showed that the OS rate in treatment group was significantly higher than that in control group (HR=0.43, 95% CI: 0.34-0.54), but the heterogeneity of the study was high (P=0.024, I(2)=52.9%). The subgroup analysis of different control treatments showed that the OS rate in treatment group was significantly higher than that in CRS control group (HR=0.63, 95% CI: 0.44-0.90), in PC control group (HR=0.37, 95% CI: 0.32-0.43), in CRS+ IPC control group (HR=0.60, 95% CI: 0.37-0.96), and the heterogeneity of each subgroup was low (CRS control group: P=0.255, I(2)=22.9%; PC control group: P=0.222, I(2)=29.9%; CRS+IPC control group: P=0.947, I(2)=0). Due to the low heterogeneity of subgroups, fixed-effect models were used to pool and analysis. The results of sensitivity analysis revealed that there was little difference between the pooled analysis results after each study was deleted, suggesting that the pooled analysis results were more reliable. Publication bias detection of each study showed Begg's test (P=0.088) >0.05 and Egger's test (P=0.138)>0.05. According to the Begg's funnel plot, the scatter point distribution was basically symmetric, indicating that there was no publication bias in the included study. Conclusion: CRS+HIPEC can improve the OS of patients with colorectal cancer peritoneal metastasis.

Abstract
Development of glycogen synthase kinase-3β (GSK-3β) inactivation-centric agents with polypharmacological profiles is increasingly recognized as a promising therapeutic strategy against the multifactorial etiopathology of Alzheimer's disease (AD). In this respect, a series of disubstituted aminopyrazole derivatives were designed and synthesized as a new class of GSK-3β inhibitors. Most of these derivatives possess GSK-3β inhibitory activities with IC50 values in the micromolar ranges, among which bisindole-substituted aminopyrazole derivative 6h displayed moderate GSK-3β inhibition (IC50 = 1.76 ± 0.19 μM), and alleviative effects against lipopolysaccharide (LPS)-induced glial inflammation in BV-2 cells and glutamate-induced oxidative neurotoxicity in HT-22 cells. Further in vivo studies indicated that compound 6h had potent anti-inflammatory effect, by showing markedly reduced microglial activation and astrocyte proliferation in the brain of LPS-injected mice. Overall, the simultaneous modulation of 6h on multiple dysfunctions of disease network highlights this structural distinctively bisindole-substituted aminopyrazole could be a useful prototype for the discovery of novel therapeutic agents to tackle AD and other GSK-3β associated complex neurological syndromes.

Abstract
PURPOSE Real-world evidence has become increasingly relevant in regulatory decision making. Compared to large regulatory bodies, the national pharmacovigilance system in Taiwan is still under development, and the aim of this study is to demonstrate how a resource-limited health authority utilizes real-world evidence in decision making. METHODS We described different sources of real-world data available in Taiwan and illustrated the structural framework that integrates real-world evidence into Taiwan's national pharmacovigilance system. Additionally, we reviewed real-world studies conducted in the past 10 years and provided examples to show how these studies influenced drug safety-related decision making in Taiwan. RESULTS During the past 10 years, real-world evidence used when making drug safety-related regulatory decisions in Taiwan was mainly generated from nationwide claims databases, but other sources of real-world data, such as national registries and large electronic hospital databases, also became available recently. Different types of real-world evidence, including drug utilization studies, risk evaluation studies, and risk minimization measure evaluation studies, have been used to support regulatory decisions in Taiwan. CONCLUSIONS Through collaborations between the government and academics, Taiwan has started to integrate real-world evidence into the national pharmacovigilance system. However, future efforts, including linkages between different sources of real-world data and improvements in procedural and methodological practices, are needed to generate more regulatory-quality real-world evidence.

Abstract
2-Azaallyl anions are valuable intermediates which have versatile applications in functionalization with various electrophiles. Decarboxylation of the imines formed from aromatic aldehydes and α,α-diphenylglycine provides an interesting and efficient way to generate delocalized 2-azaallyl anions, which display high reactivity toward different electrophiles with excellent regioselectivity at the diphenylketimino aryl carbon of the 2-azaallyl anions. The transformation produces various amines in good yields under very mild conditions. This Synpacts article highlights the recent advances on the decarboxylative umpolung synthesis of amines from carbonyl compounds.1 Introduction2 Decarboxylative Umpolung Reactions of Carbonyl Compounds with Different Electrophiles2.1 Reaction with π-Allyl–Pd(II) Species2.2 Reaction with Morita–Baylis–Hillman Adducts2.3 Reaction with Imines2.3.1 Intermolecular Reaction with N-Ts Imines2.3.2 Intramolecular Reaction with Chiral N-tert-Butanesulfinyl Imines2.4 Reaction with Aldehydes and Ketones3 Decarboxylative Umpolung Reaction of α,β-Unsaturated Aldehydes with Aldehydes4 Conclusion

Abstract
An enantioselective asymmetric annulation of 2-formylboronic acids with internal alkynes has been realized using a chiral phosphinooxazoline/palladium(II) catalyst. The reaction tolerates a variety of alkynes including the relatively inert diaryl substituted internal ones. A wide range of optically active 2,3-disubstituted indenols was afforded in high yields with good to excellent enantioselectivities (up to 99% yield and 99% ee).

Background
The immediate effect on myocardial function and deformation after coronary revascularization is incompletely studied. Effective revascularization along with perioperative myocardial injury compromises improved regional and global left ventricular function and leads to the risks of adverse perioperative events following coronary artery bypass grafting (CABG) surgery. Global longitudinal strain (GLS) assessed by speckle-tracking echocardiography (STE) has been reported as a better predictor and a more sensitive marker for postoperative ventricular remodeling.
Purpose
This study aimed to evaluate changes of left ventricular (LV) systolic function and GLS in the perioperative period during CABG and to investigate the value of GLS using two-dimensional STE in predicting short-term outcome.
Methods
A total of 22 patients who underwent elective CABG surgery (EuroSCORE II 1.84 ± 1.2) were evaluated. Transesophageal echocardiography was performed, 2D and three-dimensional echocardiography (3DE) data was acquired before sternotomy, before cardiopulmonary bypass (CPB), after bypass and after chest closure. LV GLS and tissue motion annular displacements (TMAD) of the mitral valves were quantified by 2D STE using CMQ software. LV volumes and ejection fraction (EF) were evaluated by 3DE at the same timepoints. Short-term outcomes were defined as death, stroke, myocardial infarction, acute kidney dysfunction, rehospitalization and repeated revascularization in a one-month period after surgery.
Results
Both 2D and 3DE of all patients were analyzed. The cohort had a mean age of 68.2 ± 7.2 years and 9.1% was women. Before sternotomy, GLS was -15.7 ± 2.9%. Despite little change in 3D LVEF, GLS was immediately impaired after coronary artery bypass graft (before bypass vs after chest closure, -15.9 ± 3.6% vs -13.5 ± 4.0%, P = 0.001). There was strong correlation between GLS and 3D LVEF (r=-0.77, P < 0.001), moderate correlations between GLS and absolute value of TMAD (r=-0.61, P < 0.05), between GLS and percentage of TMAD (r=-0.64, P < 0.05). Patients with poor outcome (n = 6) had a lower longitudinal strain (LS) in the apical 2-chamber (A2C) views (-14.5 ± 4.6% vs -10.8 ± 1.3%, P = 0.007) but no statistical difference between A3C and A4C views. The ROC analysis demonstrated a cutoff value -11.8% for A2C-LS to predict adverse events (AUC 0.81, P = 0.027, 95% CI 0.632-0.993), with an 83.3% sensitivity and 81.2% specificity, followed by 3D LVEF (AUC = 0.29), absolute and percentage of TMAD (AUC = 0. 21, 0.23) as less sensitive predictors of poor postoperative outcome.
Conclusion
Direct effects of myocardial deformation related to revascularization can be characterized by STE during CABG surgery. GLS could be a more sensitive parameter in the perioperative environment, which correlates well with LV global function assessed by 3D LVEF and TMAD. Early impairment of anterior and inferior wall myocardial strain after CABG may contribute to short-term adverse clinical outcome.

Abstract
Objective: To investigate the dynamic changes of copper and iron contents in brain tissue, body fluids and barriers of rats exposed to lead at different periods in order to provide a theoretical basis for the study of the mechanism of lead nerve injury. Methods: Sixty-four healthy adult SPF male SD rats were randomly divided into control group and lead exposure group, after one week of adaptive feeding, rats in the lead exposure group were treated with 250 mg/L lead acetate, and rats in control group were treated with ordinary drinking water, the experimental period was 12 weeks. After exposure for 3, 6, 9 and 12 weeks, the samples including blood, choroid plexus, cerebrospinal fluid, cortex, hippocampus, striatum, hypothalamus, amygdala, substantia nigra and cerebellum were obtained. Lead, copper and iron content in all kinds of samples were detected by Inductively Coupled Plasma Mass Spectrometry(ICP-MS). The measurement data were presented as Mean±SD, Comparison of metal contents in different tissues of rats at different time analyzed using repeated measurement analysis of variance, Two-variable correlation analysis using Spearman correlation test.The relationship between lead exposure experiod and copper and iron in samples was studied by using trend test. Results: After 12 weeks of lead exposure compared with the control group, lead contents in cortex, hippocampus, striatum, hypothalamus, amygdala, substantia nigra and cerebellum of rats were 2.21, 2.44, 2.95, 3.53, 4.01, 1.85 and 2.86 folds of control group, and the differences were statistically significant(P<0.05). At the same time, lead content in blood, cerebrospinal fluid,choroid plexus, brain microvessels and bones increased. The increase rate in the amygdala and cerebrospinal fluid ranked first among brain tissue or barrier,which were 4.01 and 3.0 folds respectively. Compared with the control group, Compared with the control group, copper content in cortex,hippocampus, striatum, hypothalamus,amygdala, cerebellum,blood,cerebrospinal fluid,choroid plexus and cerebral microvasculature showed an increasing trend among rats following 3,6,9,12 weeks of lead exposure. Copper content change in the striatum was highest among all brain tissue. The increase rate of copper content in the striatum was at the top among brain tissues. After 12 weeks of lead exposure,copper content in brain microvessels was 4.98 folds higher than that of the control group (P<0.05). After lead exposure at different periods,the iron content in the cortex, hippocampus, striatum,cerebrospinal fluid,choroid plexus and brain microvessels of experimental rats all increased(P<0.05). And the iron increase rate in the hypothalamus or cerebrospinal fluid increase ranked first among brain tissues or body fluid the most obviously. Conclusion: With the increase of exposure time, lead exposure can changes in the contents of copper and iron in different brain tissues,body fluids and barriers in rats,among which, the contents of copper and iron in the amygdala,cerebrospinal fluid and brain microvessels increase significantly. This may be related to nerve damage from lead exposure.

Abstract
AIMS Allopurinol carries a well-known risk of cutaneous adverse reactions (CARs). Although febuxostat, a xanthine-oxidase inhibitor with different chemical structure, has been considered an alternative to allopurinol, post-marketing case reports of life-threatening febuxostat-related CARs have been reported. We aimed to compare the risk of CARs between allopurinol and febuxostat in real-world settings and to assess the impact of the market entry of febuxostat on allopurinol use and associated CARs. METHODS A nationwide study was conducted using Taiwan's National Health Insurance Research Database. In the new-user cohort study, patients who received their first prescriptions of allopurinol or febuxostat were included, and Poisson regression was used to estimate the incidence rate ratios (IRRs) of CARs. In the interrupted time series analysis, time series data on new users and incidence rate of CARs were divided into three periods based on the reimbursement scheme of febuxostat in Taiwan, and segmented regression models were used to estimate changes in both the level and trend in each period. RESULTS We identified 526 cases of CARs with 487 among new users of allopurinol and 39 among new users of febuxostat (incidence rate: 15.37 vs 3.48 per 1000 person-years). Allopurinol was associated with higher risk of CARs (adjusted IRR 5.55, 95% CI [3.97-7.76]), mild CARs (1.86, [1.24-2.81]), severe CARs (16.75, [8.87-31.62]) and fatal CARs (16.18, [5.05-51.83]) than febuxostat. The overall incidence rates of xanthine-oxidase inhibitor-related CARs decreased from 15.28 to 14.28 per 1000 person-years after the initial reimbursement of febuxostat and further decreased to 9.46 after the reimbursement coverage of febuxostat expanded; however, the changes were not statistically significant. CONCLUSION Febuxostat can be considered an alternative for patients carrying risk factors for allopurinol-related CARs. However, since there were fatal cases of febuxostat-related CARs, the closely monitoring of symptoms of CARs during the initiation of febuxostat is still warranted.

Abstract
The drug-injury relief system in Taiwan was implemented 20 years ago with the goal of providing timely relief for drug injuries incurred by the proper use of legal drugs. This system utilizes a nonlitigation expert review process to evaluate drug-injury relief applications, and 2,732 applications have been reviewed from 1999-2016. Of these, 1,572 applications received relief payments, an approval rate of 58%. Average review timeframes per application have decreased from 248 days (2003-2011) to 182 days (2012-2016). Most adverse drug reactions (ADRs) for approved cases involved skin and subcutaneous tissue disorders (67%), with allopurinol being the primary culprit drug. A recent decline observed for such ADRs may reflect the influences of promotional activities and policy initiatives carried out according to informed analysis from drug-injury relief applications, which suggests that the drug-injury relief system can also play an important public health role in enhancing drug safety.

Abstract
OBJECTIVE After discovering the association between the HLA-B*15:02 allele and carbamazepine-related severe cutaneous adverse reactions (SCARs), particularly in Southeastern Asian populations, clinical strategies to prevent carbamazepine-related SCARs have changed. We aimed to investigate 10-year trends in carbamazepine use and carbamazepine-related SCARs and to examine the patterns and determinants of HLA-B*15:02 screening in Taiwan. METHODS A nationwide study was performed using Taiwan's National Health Insurance Research Database. In the first part of the study, new users of carbamazepine were included, and those who experienced SCAR-related admissions were further identified. In the second part of the study, recipients of HLA-B*15:02 screening (reimbursed by Taiwan's National Health Insurance since June 2010) were included and multivariate logistic regression was used to explore factors associated with the use of screening. RESULTS The numbers of new users of carbamazepine and SCAR cases decreased remarkably during the 10-year period (-82.6% and -87.1%, respectively), and the incidence rates of SCARs showed a downward trend after 2011. The screening rate of the HLA-B*15:02 allele increased to 24.9% in 2014. Neurologists (odds ratio 12.33, 95% confidence interval 9.30-16.35), psychiatrists (9.97, 7.31-13.61), and neurosurgeons (3.23, 2.42-4.32) were more likely to perform screening tests than other specialties were. Physicians practicing in medical centers (6.00, 5.51-6.54) were more likely to perform screening tests than those practicing in other hospitals, whereas the screening rates in clinics remained at 0.0% throughout the study period. SIGNIFICANCE In recent years, the number of carbamazepine-related SCAR cases has decreased substantially in Taiwan. However, only one-fourth of new users of carbamazepine received HLA-B*15:02 screening, and there were considerable disparities in the screening rates across different physician groups. Policymakers should consider solutions to barriers to implementing screening tests in clinical practice and should not neglect the value of other safety communications and regulations to complement the limitations of pharmacogenomic testing.

Abstract
OBJECTIVE Liver is uniquely vulnerable during sepsis. MicroRNA-155 (miR-155) is confirmed to play crucial roles in septic liver injury. The present study aims to investigate the mechanisms of miR-155 in septic liver injury. METHODS The sepsis model was established by intraperitoneal injection of lipopolysaccharide (LPS) in mice. Mice were divided into four groups: Vehicle, miR-155 antagomir, LPS, LPS+ miR-155 antagomir. The survival rate and body weight were monitored. Liver injury was assessed by H&E staining. The levels of serum ALT and inflammatory cytokines were determined by ELISA kits. Oxidative stress was detected by MDA and SOD detection kits. The miR-155, Nrf-2, and markers related to oxidative stress, endoplasmic reticulum (ER) stress, mitochondrial injury and apoptosis were detected by western blotting and qPCR. Apoptosis in liver tissues was detected by TUNELstaining. RESULTS MiR-155 antagomir alleviated liver injury as evidenced by enhancing survival rate and body weight, inhibiting inflammatory cell infiltration, liver cells necrosis and decreasing ALT level. The productions of TNF-α, IL-6 were suppressed, while anti-inflammatory cytokine IL-10 was promoted by miR-155 antagomir. Oxidative stress was inhibited by miR-155 antagomir via enhancing nuclear factor, erythroid 2-like 2 (Nrf-2) expression. ER stress and Cytochrome C (Cyto-C) release were restrained by miR-155 antagomir. Sepsis-induced apoptosis was repressed by miR-155 antagomir as manifested by the decreased levels of Bax, cleaved caspase-12, 9 and 3, and increased levels of Bcl-2 and uncleaved PARP. CONCLUSION MiR-155 antagomir relieved septic liver injury through inhibiting oxidative stress-mediated ER stress, mitochondrial dysfunction and apoptosis via targeting Nrf-2, suggesting miR-155 as a therapeutic target for septic liver injury.

Abstract
Type 2 diabetes mellitus (T2DM) is associated with an increased risk of the development of colorectal cancer (CRC). A previous study revealed that the levels of arginine-specific mono-ADP-ribosyltransferase 1 (ART1) in CRC tissues from patients with T2DM were higher than in non-diabetic patients. Hyperglycemia, which is a risk factor of cancer, is a common feature of T2DM; however, the effects of ART1 on glycolysis and energy metabolism in CRC cells under high-glucose conditions remains to be elucidated. β-caryophyllene (BCP) has been reported to exert anticancer and hypoglycemic effects. In the present study, CT26 cells were cultured under a high-glucose conditions and the expression levels of relevant factors were detected by western blotting. Cell Counting Kit-8 assay, flow cytometry, Hoechst 33258 staining, ATP assay and lactic acid assay were used to detect the proliferation, apoptosis and energy metabolism of CT26 cells. To observe the effects of ART1 and BCP on tumor growth in vivo, CT26 cell tumors were successfully transplanted into BALB/c mice with T2DM. The results demonstrated that overexpression of ART1 may increase glycolysis and energy metabolism in CT26 CRC cells under high glucose conditions by regulating the protein kinase B/mammalian target of rapamycin/c‑Myc signaling pathway and the expression of glycolytic enzymes. BCP inhibited the effects induced by ART1, which may be due to a BCP-induced reduction in the expression levels of ART1 via nuclear factor-κB. Therefore, ART1 may be considered a therapeutic target for the treatment of diabetic patients with CRC.

Abstract
RATIONALE Hand, foot and mouth disease (HFMD) is caused by enterovirus. The virus may exist in secretions. PATIENT CONCERNS Five neonates had symptoms of fever and maculopapular rashes involving face, trunk, breech, arms, and legs, especially scattering on palms and feet. Blood, oropharyngeal fluid, urine, and cerebrospinal fluid (CSF) samples were collected and detected for further diagnoses with the consent of the infants' parents. Some of them suffered aseptic meningitis. DIAGNOSES They were diagnosed as HFMD with CSF enterovirus positive. INTERVENTIONS All of them continued breastfeed. Water bag was used during the pyrogenic stage. Antibiotics were administrated at first and withdrawn as soon as possible. OUTCOMES None of them developed into brainstem encephalitis or pulmonary edema and they all recovered well. LESSONS HFMD is more common in neonates than it has been thought. Enterovirus may exist in neonatal CSF and cause CSF cell to increase similar to purulent meningitis. Medical history, physical examination, and CSF enterovirus detection are important in making correct diagnosis. Unlike bacterial infection, HFMD is a self-limited disease. Once HFMD is determined and bacterial infection is ruled out, antibiotics should be avoided.
