Abstract
Reputable evidence from multiple studies suggests that excessive and uncontrolled inflammation plays an indispensable role in mediating, amplifying, and protracting acute lung injury (ALI). Traditionally, immunity and energy metabolism are regarded as separate functions regulated by distinct mechanisms, but recently, more and more evidence show that immunity and energy metabolism exhibit a strong interaction which has given rise to an emerging field of immunometabolism. Mammalian lungs are organs with active fatty acid metabolism, however, during ALI, inflammation and oxidative stress lead to a series metabolic reprogramming such as impaired fatty acid oxidation, increased expression of proteins involved in fatty acid uptake and transport, enhanced synthesis of fatty acids, and accumulation of lipid droplets. In addition, obesity represents a significant risk factor for ALI/ARDS. Thus, we have further elucidated the mechanisms of obesity exacerbating ALI from the perspective of fatty acid metabolism. To sum up, this paper presents a systematical review of the relationship between extensive fatty acid metabolic pathways and acute lung injury and summarizes recent advances in understanding the involvement of fatty acid metabolism-related pathways in ALI. We hold an optimistic believe that targeting fatty acid metabolism pathway is a promising lung protection strategy, but the specific regulatory mechanisms are way too complex, necessitating further extensive and in-depth investigations in future studies.

Abstract
BACKGROUND Hydrochlorothiazide, a diuretic commonly used for the treatment of hypertension, is often associated with serious metabolic side effects. Pyrrosia petiolosa (Christ) Ching is a traditional Chinese medicine that possesses diuretic properties, without any obvious side effects. AIM To evaluate the diuretic effect of P. petiolosa (Christ) Ching and to elucidate its underlying mechanism of action. METHODS Extracts obtained from different polar components of P. petiolosa (Christ) Ching were analyzed for toxicity in a Kunming mouse model. The diuretic effects of the extracts were compared to that of hydrochlorothiazide in rats. In addition, compound isolation procedures, cell assays of Na-Cl cotransporter inhibition and rat diuretic test of monomeric compounds were conducted to identify the active ingredients in the extract. Subsequently, homology modeling and molecular docking were performed to explain the reason behind the diuretic activity observed. Finally, LC-MS analysis was used to elucidate the underlying mechanism of action of P. petiolosa (Christ) Ching. RESULTS No toxicity was observed in mice administered P. petiolosa (Christ) Ching extracts. The ethyl acetate fraction showed the most significant diuretic effect. Similar results were obtained during the analysis for Na+ content in rat urine. Further separation of P. petiolosa (Christ) Ching components led to the isolation of methyl chlorogenate, 2',3'-dihydroxy propyl pentadecanoate, and β-carotene. Results from cell assays showed that the Na-Cl cotransporter inhibitory activity of methyl chlorogenate was greater than that of hydrochlorothiazide. This result was again confirmed by the diuresis tests of monomeric compounds in rats. The molecular simulations explain the stronger interactions between the methyl chlorogenate and Na-Cl cotransporter. Of the compounds determined using LC-MS analysis, 185 were identified to be mostly organic acids. CONCLUSIONS P. petiolosa possesses significant diuretic activities without any obvious toxicity, with least two possible mechanisms of action. Further study on this herb is warranted.

Abstract
The prototypical calcium release-activated calcium (CRAC) channel, composed of STIM1 and Orai1, is a sought-after drug target for treating autoimmune disorders. Herein, we identified two novel and selective CRAC channel inhibitors, the indole-like compound C63368 and pyrazole core-containing compound C79413, potently and reversibly inhibiting the CRAC channel with low micromolar IC50s and sparing various off-target ion channels. These two compounds did not inhibit STIM1 activation or its coupling with Orai1, nor did they affect the channel's calcium-dependent fast inactivation. Instead, they directly acted on the Orai1 protein, with the channel's pore geometry profoundly affecting their potencies. In vitro, C63368 and C79413 effectively inhibited Jurkat cell proliferation and cytokines production in human T lymphocytes. Intragastric administration of C63368 and C79413 to mice yielded great therapeutic benefits in psoriasis and colitis animal models of autoimmune disorders, reducing serum cytokines production and significantly relieving pathological symptoms. It's worth noting, that this study provided the first insight into the characterization and mechanistic investigation of an indole-like CRAC channel antagonist. Altogether, the identification of these two highly selective CRAC channel antagonists, coupled with the elucidation of their action mechanisms, not only provides valuable template molecules but also offers profound insights for drug development targeting the CRAC channel.

Abstract
Potassium Calcium-Activated Channel Subfamily N1 (KCNN1), an integral membrane protein, is thought to regulate neuronal excitability by contributing to the slow component of synaptic after hyperpolarization. However, the role of KCNN1 in tumorigenesis has been rarely reported, and the underlying molecular mechanism remains unclear. Here, we report that KCNN1 functions as an oncogene in promoting breast cancer cell proliferation and metastasis. KCNN1 was overexpressed in breast cancer tissues and cells. The pro-proliferative and pro-metastatic effects of KCNN1 were demonstrated by CCK8, clone formation, Edu assay, wound healing assay and transwell experiments. Transcriptomic analysis using KCNN1 overexpressing cells revealed that KCNN1 could regulate key signaling pathways affecting the survival of breast cancer cells. KCNN1 interacts with ERLIN2 and enhances the effect of ERLIN2 on Cyclin B1 stability. Overexpression of KCNN1 promoted the protein expression of Cyclin B1, enhanced its stability and promoted its K63 dependent ubiquitination, while knockdown of KCNN1 had the opposite effects on Cyclin B1. Knockdown (or overexpression) ERLNI2 partially restored Cyclin B1 stability and K63 dependent ubiquitination induced by overexpression (or knockdown) of KCNN1. Knockdown (or overexpression) ERLIN2 also partially neutralizes the effects of overexpression (or knockdown) KCNN1-induced breast cancer cell proliferation, migration and invasion. In paired breast cancer clinical samples, we found a positive expression correlations between KCNN1 and ERLIN2, KCNN1 and Cyclin B1, as well as ERLIN2 and Cyclin B1. In conclusion, this study reveals, for the first time, the role of KCNN1 in tumorigenesis and emphasizes the importance of KCNN1/ERLIN2/Cyclin B1 axis in the development and metastasis of breast cancer.

Abstract
Intercellular signaling and component conduction are essential for multicellular organisms' homeostasis, and mitochondrial transcellular transport is a key example of such cellular component exchange. In physiological situations, mitochondrial transfer is linked with biological development, energy coordination, and clearance of harmful components, remarkably playing important roles in maintaining mitochondrial quality. Mitochondria are engaged in many critical biological activities, like oxidative metabolism and biomolecular synthesis, and are exclusively prone to malfunction in pathological processes. Importantly, severe mitochondrial damage will further amplify the defects in the mitochondrial quality control system, which will mobilize more active mitochondrial transfer, replenish exogenous healthy mitochondria, and remove endogenous damaged mitochondria to facilitate disease outcomes. This review explores intercellular mitochondrial transport in cells, its role in cellular mitochondrial quality control, and the linking mechanisms in cellular crosstalk. We also describe advances in therapeutic strategies for diseases that target mitochondrial transfer.

Abstract
The proton-activated chloride (PAC) channel plays critical roles in ischemic neuron death, but its activation mechanisms remain elusive. Here, we investigated the gating of PAC channels using its novel bifunctional modulator C77304. C77304 acted as a weak activator of the PAC channel, causing moderate activation by acting on its proton gating. However, at higher concentrations, C77304 acted as a weak inhibitor, suppressing channel activity. This dual function was achieved by interacting with 2 modulatory sites of the channel, each with different affinities and dependencies on the channel's state. Moreover, we discovered a protonation-independent voltage activation of the PAC channel that appears to operate through an ion-flux gating mechanism. Through scanning-mutagenesis and molecular dynamics simulation, we confirmed that E181, E257, and E261 in the human PAC channel serve as primary proton sensors, as their alanine mutations eliminated the channel's proton gating while sparing the voltage-dependent gating. This proton-sensing mechanism was conserved among orthologous PAC channels from different species. Collectively, our data unveils the polymodal gating and proton-sensing mechanisms in the PAC channel that may inspire potential drug development.

Abstract
Overfeeding and a lack of exercise are increasingly causing obesity in dogs, which has become a big problem threatening the health of dogs. Therefore, it is necessary to investigate how dietary regulations can help to improve dogs' body conditions and minimize obesity. This study was carried out to investigate the effects of dietary mulberry leaf powder (MLP) supplementation on the growth performance, lipid metabolism parameters, and gut microbiota of Chinese indigenous dogs. Fifteen Chinese indigenous dogs (6.34 ± 0.56 kg) were randomly assigned to three treatment groups and received either the control diet (CON), high-fat diet (HF), or high-fat diet containing 6% Mulberry leaf powder (MLP) for four weeks. The CON group received a basal diet, the HF group received a basal diet supplemented with 10% lard, and the MLP group received a basal diet supplemented with 10% lard and 6% MLP. The trial lasted for four weeks. The growth performance, lipid metabolism parameters, immune globulins, cytokines, and fecal microbiota were measured. Results showed that there was no significant difference in growth performance. The MLP group appeared to have decreased (p < 0.05) the serum level of low-density lipoprotein cholesterol (LDL-C) and apoliprotein-A1(APO-A1) in serum. The MLP group appeared to have higher (p < 0.05) serum immune globulin A (IgA) levels. UPGMA results showed that the MLP group was closer to the CON group than to the HF group. LEfSe analysis showed that dietary supplementation with MLP contributed to an alteration in the genus Alloprevotella, Sarcina, and species belonging to the Bacteroides and Lactobacillus genus. Overall, the dietary supplementation of 6% MLP can improve lipid metabolism conditions and immunity in high-fat-diet-fed dogs, and can alter the gut microbial composition of dogs.

Abstract
Mulberry is an economically important plant in the sericulture industry and traditional medicine. However, the genetic and evolutionary history of mulberry remains largely unknown. Here, this work presents the chromosome-level genome assembly of Morus atropurpurea (M. atropurpurea), originating from south China. Population genomic analysis using 425 mulberry accessions reveal that cultivated mulberry is classified into two species, M. atropurpurea and M. alba, which may have originated from two different mulberry progenitors and have independent and parallel domestication in north and south China, respectively. Extensive gene flow is revealed between different mulberry populations, contributing to genetic diversity in modern hybrid cultivars. This work also identifies the genetic architecture of the flowering time and leaf size. In addition, the genomic structure and evolution of sex-determining regions are identified.

Abstract
OBJECTIVE To observe the effect of Shenbing Decoction Ⅲ for improving renal function and pathology in rats with 5/6 nephrectomy and analyze its therapeutic mechanism for renal fibrosis in chronic kidney disease using network pharmacology combined with molecular docking. METHODS Forty male SD rats were randomized into two groups to receive two-staged 5/6 nephrectomy (n=30) or sham operation (n=10), and 2 weeks after the final operation, serum creatinine level of the rats was measured. The rats with nephrectomy were further randomized into Shenbing Decoction Ⅲ group, losartan group and model group for daily treatment with the corresponding drugs via gavage starting at 1 week after 5/6 nephrectomy. After 16 weeks of treatment, serum creatinine and urea nitrogen levels of the rats were measured, and HE staining and Western blotting were used to examine the changes in renal pathology and fibrosis-related factors. Network pharmacology combined with molecular docking study was performed to explore the therapeutic mechanism Shenbing Decoction Ⅲ against renal fibrosis in chronic kidney disease, and Western blotting was used to verify the expressions of the core targets. RESULTS Compared with those in the model group, the rats receiving 5/6 nephrectomy and Shenbing Decoction Ⅲ treatment showed significantly reduced serum creatinine and urea nitrogen levels, lessened renal pathologies, and improvement of the changes in epithelial mesenchymal transition-related proteins. Network pharmacological analysis showed that the main active ingredients of Shenbing Decoction Ⅲ were acacetin, apigenin, eupatilin, quercetin, kaempferol and luteolin, and the key targets included STAT3, SRC, CTNNB1, PIK3R1 and AKT1. Molecular docking study revealed that the active ingredients of Shenbing Decoction Ⅲ had good binding activity to the key targets. Western blotting showed that in rats with 5/6 nephrectomy, treatment with Shenbing Decoction Ⅲ obviously restored the protein expression of STAT3, PI3K, and AKT in renal tissue. CONCLUSION Shenbing Decoction Ⅲ can reduce renal injury induced by 5/6 nephrectomy in rats, and its therapeutic effects are mediated possibly by its main pharmacologically active ingredients that alleviate renal fibrosis via modulating multiple targets including STAT3, PIK3R1, and AKT1.

Abstract
Acute lung injury (ALI), caused by intrapulmonary or extrapulmonary factors such as pneumonia, shock, and sepsis, eventually disrupts the alveolar-capillary barrier, resulting in diffuse pulmonary oedema and microatasis, manifested by refractory hypoxemia, and respiratory distress. Not only is ALI highly lethal, but even if a patient survives, there are also multiple sequelae. Currently, there is no better treatment than supportive care, and we urgently need to find new targets to improve ALI. Histone deacetylases (HDACs) are epigenetically important enzymes that, together with histone acetylases (HATs), regulate the acetylation levels of histones and non-histones. While HDAC inhibitors (HDACis) play a therapeutic role in cancer, inflammatory, and neurodegenerative diseases, there is also a large body of evidence suggesting the potential of HDACs as therapeutic targets in ALI. This review explores the unique mechanisms of HDACs in different cell types of ALI, including macrophages, pulmonary vascular endothelial cells (VECs), alveolar epithelial cells (AECs), and neutrophils.

Abstract
The accurate identification of high-risk zones and risk source-sink responses for heavy-metal (HM) contamination of agroecosystems remains challenging due to involving multiple environmental media such as soils, dustfall, and crops and a wide range of evaluation criteria and constraints. This study established a novel evaluation model based on the integration of Geographical Information Systems (GIS) and multi-criteria decision analysis (MCDA) to assess agroecosystem risk in the Lihe River watershed, China. Bivariate local indicators of spatial association (LISA) were adopted to explore the spatial interaction of risk sources and sinks with outputs ranging from 0.0003 (no risk) to 0.83 (high risk). Areas with moderate, considerable, and high risk constituted 67.4 % of the total land area, and only 1.8 % of the area was classed as low risk. Central urban and eastern areas around Taihu Lake were risk accumulation regions that needed more remedial attention. Risk cluster zones in the central urban area involved significant source-sink response relationships with the spatial distribution of industries, whereas eastern zones were linked to vehicular traffic distribution, accounting for 27.5 % and 16.5 % of the total area, respectively. This study provides a new methodological framework for the assessment of environmental risk, risk zonation, and risk source-sink spatial interaction in agroecosystems.

Abstract
Papillary thyroid cancer (PTC) is one of the most common malignant tumors in female, and estrogen can affect its progression. However, the targets and mechanisms of estrogen action in PTC remain unclear. Therefore, this study focuses on the relationship between estrogen-related genes (ERGs) expression and prognosis in PTC, particularly neuropeptide U (NMU), and its important role in tumor progression. Based on The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases, differentially expressed genes (DEGs) predominantly enriched in ERGs were identified between PTC and normal tissue. Then, we identified ERGs that contributed most to PTC prognosis, including Transducer of ERBB2 1 (TOB1), trefoil factor 1 (TFF1), phospholipase A and acyltransferase 3 (PLAAT3), NMU, kinesin family member 20A (KIF20A), DNA topoisomerase II alpha (TOP2A), tetraspanin 13 (TSPAN13), and carboxypeptidase E (CPE). In addition, we confirmed that NMU was highly expressed in PTC and explored the effect of NMU on PTC cells proliferation in vitro and in vivo. The results showed that the proliferative capacity of PTC cells was significantly reduced with NMU knockdown. Moreover, the phosphorylation levels of the Kirsten rat sarcoma virus (KRAS) signaling pathway were significantly lower with NMU knockdown. These results suggest that ERGs, especially NMU, may be novel prognostic indicators in PTC.

Abstract
Objective: To investigate the efficacy and safety of CT-guided radiofrequency ablation of posterior root of spinal nerve in the treatment of postherpetic neuralgia (PHN). Methods: A total of 102 PHN patients (42 males and 60 females) aged (69.7±9.4) years who underwent CT-guided radiofrequency ablation of posterior root of spinal nerve in the Department of Pain Medicine of the Affiliated Hospital of Jiaxing University from January 2017 to April 2020 were retrospectively included. Patients were followed up, and numerical rating scale (NRS) score, Pittsburgh sleep quality index (PSQI), satisfaction score and complications before surgery (T0) and at 1 d (T1), 3 months (T2), 6 months (T3), 9 months (T4) and 12 months (T5) after surgery were recorded. Results: The NRS score of PHN patients at T0, T1, T2, T3, T4, and T5 [M(Q1, Q3)] was 6(6, 7), 2(2, 3), 3(2, 4), 3(2, 4), 2(1, 4), 2(1, 4), respectively. Likewise, the PSQI score [M(Q1, Q3)] at aforementioned time points was 14(13, 16), 4(3, 6), 6(4, 8), 5(4, 6), 4(2, 8), 4(2, 9), respectively. Compared with T0, the NRS and PSQI scores at all time points from T1 to T5 were lower, with statistically significant differences (all P<0.001). The overall effective rate of surgery at 1 year postoperatively was 71.6% (73/102) with a satisfaction score of 8(5, 9), and the recurrence rate was 14.7% (15/102) with a recurrence time of (7.5±0.8) months. The main postoperative complication was numbness, with an incidence of 86.0% (88/102), and the degree of numbness gradually decreased with time. Conclusion: CT-guided radiofrequency ablation of posterior root of spinal nerve for PHN has a high effective rate and a low recurrence rate, with high safety profile, and may be a feasible surgical option for the treatment of PHN.

Abstract
RATIONALE Limited patients with locoregionally advanced nasopharyngeal carcinoma (LA-NPC) have achieved complete response (CR) from induction chemotherapy (IC). Neoadjuvant immunotherapy combined with chemotherapy has marked therapeutic effects in some locoregionally advanced solid tumors. However, its efficacy and safety of NPC have not been reported so far. The rapid response of neoadjuvant tislelizumab combined with chemotherapy on LA-NPC may be associated with long-term survival benefit. PATIENT CONCERNS A 57-year-old male patient presented with a 2-month history of bloody nasal discharge and right neck mass for 2 weeks. DIAGNOSIS The patient was eventually diagnosed with nasopharyngeal nonkeratinizing undifferentiated cell carcinoma (stage IVA). INTERVENTIONS The patient received tislelizumab combined with nanoparticle albumin-bound paclitaxel (nab-paclitaxel) nab-paclitaxel plus cisplatin for 4 cycles, followed by cisplatin-based concurrent chemoradiotherapy (CCRT). OUTCOMES A partial response (PR) was achieved after 2 cycles of tislelizumab and nab-paclitaxel plus cisplatin, and CR was achieved after 4 cycles of neoadjuvant treatment. The duration of response lasted 24 months, and the patient was still in CR as of November 2022. The patient had no serious adverse event (AEs) during the treatment. LESSONS This case report showed that tislelizumab combined with cisplatin plus nab-paclitaxel followed CCRT for treatment of patients with LA-NPC may receive a fast and durable response with a manageable safety profile and long-term survival.

Objective: To explore the efficacy and safety of transcatheter pulmonary valve perforation in the treatment of neonatal pulmonary atresia with intact ventricular septum (PA-IVS). Methods: The clinical data on surgical treatment and follow-up in 16 patients with PA-IVS who underwent transcatheter pulmonary valve perforation in Women and Children's Hospital, Qingdao University from October 2018 to October 2021 were analyzed retrospectively. The right ventricular systolic pressure and percutaneous oxygen saturation (SpO2) were compared before and after operation. In addition, the SpO2 and echocardiographic data at preoperative and the last follow-up were compared. Comparisons between groups were performed using paired-samples t test. Results: Among the 16 patients (10 males and 6 females) with the age at operation of 19 (14, 26) days, 12 cases underwent transcatheter pulmonary valve perforation successfully, 2 cases were transferred to surgery department for open-heart pulmonary valvulotomy, and the remaining 2 cases were transmitted to surgery department for transthoracic pulmonary valve perforation. The age at operation of the 12 patients who underwent transcatheter pulmonary valve perforation was 18 (14, 27) days, and the weight was (3.6±0.4) kg. The immediate postoperative right ventricular systolic pressure decreased significantly ((57±16) vs. (95±19) mmHg (1 mmHg=0.133 kPa), t=7.49, P<0.001), and the postoperative SpO2 was improved effectively (0.90±0.48 vs.0.75±0.09, t=-5.61, P<0.001). The follow-up time was 22 (7, 33) months for 12 patients who underwent transcatheter pulmonary valve perforation successfully. At the last follow-up, the ratio of right to left ventricular transverse diameter was significantly higher than that before operative (0.55±0.05 vs. 0.45±0.05, t=-3.27,P=0.007). Furthermore, the Z-scores of pulmonary valvular diameter (-0.78±0.23 vs. -1.73±0.56, t=-8.52, P<0.001) and the tricuspid valvular diameter (-0.52±0.12 vs. -1.46±0.38, t=-10.40, P<0.001) were all significantly higher than preoperative data. At last, all the patients achieved biventricular circulation without death or major complications. Conclusion: Transcatheter pulmonary valve perforation is a safe and effective therapy for neonatal PA-IVS, and its curative effect has been confirmed by the medium follow-up data.

Abstract
Porcine parvovirus (PPV) is the primary cause of reproductive disorders in pigs. The porcine parvovirus 7 (PPV7) subtype was first identified in the United States in 2016. In this study, PPV7 was detected in different porcine samples, including serum, feces, saliva, and milk, from 69 pig farms in the Fujian and Guangdong regions of South China, and its coinfection with porcine circovirus 2 (PCV2), porcine circovirus 3 (PCV3), and porcine reproductive and respiratory syndrome virus (PRRSV) was determined. Whole-genome sequencing, phylogenetic analysis, and recombination analysis were performed on seven isolates, with each selected isolate originating from a different farm. There was a high rate of PPV7 positivity in blood, stool, and saliva but PPV7 DNA was absent from breast milk. The findings also showed that PPV7-positive samples had a high rate of coinfection with PCV2, PCV3, and PRRSV. Real-time PCR was used to determine the viral copy numbers of PCV2, PCV3, PRRSV, and PPV7 in serum samples and to assess whether PPV7 affected PCV2, PCV3, and PRRSV viral loads. Phylogenetic analysis showed that PPV7e and PPV7f were the most prevalent and widespread subtypes in the Fujian and Guangdong regions, respectively. While the PPV7a, PPV7b, PPV7c, and PPV7f subtypes were most prevalent in Fujian Province, PPV7a-e subtypes were prevalent in Guangdong, indicating that PPV7 has rich genetic diversity in these regions. A putative recombinant strain, 21FJ09, was identified using SimPlot and the Recombination Detection Program 4 software.

Abstract
The bacterial sodium channel NaChBac is the prokaryotic prototype for the eukaryotic NaV and CaV channels, which could be used as a relatively simple model to study their structure–function relationships. However, few modulators of NaChBac have been reported thus far, and the pharmacology of NaChBac remains to be investigated. In the present study, we show that the spider toxin κ-LhTx-1, an antagonist of the KV4 family potassium channels, potently inhibits NaChBac with an IC50 of 491.0 ± 61.7 nM. Kinetics analysis revealed that κ-LhTx-1 inhibits NaChBac by impeding the voltage-sensor activation. Site-directed mutagenesis confirmed that phenylalanine-103 (F103) in the S3–S4 extracellular loop of NaChBac was critical for interacting with κ-LhTx-1. Molecular docking predicts the binding interface between κ-LhTx-1 and NaChBac and highlights a dominant hydrophobic interaction between W27 in κ-LhTx-1 and F103 in NaChBac that stabilizes the interface. In contrast, κ-LhTx-1 showed weak activity on the mammalian NaV channels, with 10 µM toxin slightly inhibiting the peak currents of NaV1.2–1.9 subtypes. Taken together, our study shows that κ-LhTx-1 inhibits the bacterial sodium channel, NaChBac, using a voltage-sensor trapping mechanism similar to mammalian NaV site 4 toxins. κ-LhTx-1 could be used as a ligand to study the toxin–channel interactions in the native membrane environments, given that the NaChBac structure was successfully resolved in a nanodisc.

Abstract
Objective: To summarize the interim outcome and right heart development of pulmonary atresia with intact ventricular septum (PA-IVS) in children after fetal cardiac intervention (FCI). Methods: The clinical data of 5 live births underwent FCI from October 2018 to April 2019 in Women and Children's Hospital, Qingdao University were analyzed retrospectively. The development of right ventricle (RV) and tricuspid valve (TV) in uterus after FCI, at birth, the age of 6 months, 1 year and 2 years, and the final outcome were assessed. Results: Five PA-IVS fetuses were included in this study. The first evaluation was performed at 24-26 weeks of gestational age, and the FCI was performed at 26-28 weeks of gestational age. During the follow-up of 6 weeks after FCI, the minimum diameter of tricuspid annulus increased from 0.85 cm to 0.92 cm, and the minimum Z-score of tricuspid annulus decreased from -0.03 to -1.62. The minimum values of TV/mitral valve annular diameter and RV/left ventricular length ratios of all fetuses increased from 0.57, 0.52 to 0.88, 0.82, respectively. The maximum tricuspid regurgitation velocity decreased from 4.60 m/s to 3.64 m/s. No severe hemodynamic change was found in any of the fetuses. All 5 fetuses were born alive. Three cases underwent percutaneous balloon pulmonary valvuloplasty (PBPV) and stent implantation for ductus arteriosus. Two cases received PBPV alone. At follow-up (26 to 32 months), obvious development of TV was observed 6 months to 1 year after birth in 5 cases with the growth rate ranging from 19.64% to 40.00%. Meanwhile, the RV development was relatively slow at 6 months with the growth rate ranging from 9.41% to 21.42%. There were individual differences in RV development at 2 years. The growth and development of all children were equal to healthy children of the same age with the body mass index less than 18.4 kg/m2. At the last follow-up, all children had a transcutaneous oxygen saturation of greater than 0.95, three became biventricular circulation and two had circulation approximation to biventricular circulation with almost closed stent. Conclusions: The findings support the potential of development of right ventricular and tricuspid valve for fetuses with PA-IVS underwent FCI. All fetuses underwent FCI received intervention after birth, and biventricular circulation can be realized finally. The development of right ventricular and tricuspid valve is not proportional. In utero, the right ventricle develops rapidly, and the development of tricuspid valve is more advantageous after birth.

Abstract
Background The association between conventional folic acid supplement (FAS) in pregnancy and the occurrence of adverse pregnancy outcomes, newborn defects has been proven. However, recent researches have reported a weakened association. Based on the different maternal metabolism capability of folic acid, it's beneficial for clinicians to provide pregnant women with different doses of FAS, that's individualized FAS. Subjects and Methods A total of 2,677 pregnant women in Dazu, Chongqing, China were recruited in this cohort study. 1,539 women volunteered to receive individualized FAS, in which FAS dose increased with the risk level of maternal genotype? specify MTHFR and MTRR (write in full then abbreviate bracket open and close) while 1,138 women received conventional FAS with unified FAS dose. Additionally, 1,964 pregnant women without FAS were retrospectively analyzed as the control. Finally, the incidence of adverse pregnancy outcomes and newborn defects were recorded. Results Based on the genotype of MTHFR and MTRR, women were identified as five risk levels of folic acid metabolism. The distributions of genotype and risk levels were not significantly different between FAS-individualized supplement group and FAS-unified supplement group. However, compared with control or FAS-unified supplement group, the incidence of spontaneous abortion, prolonged pregnancy, premature labor, fetal macrosomia and congenital heart disease were significantly decreased in FAS-individualized supplement group. In subgroup analysis, individualized FAS significantly improved pregnancy outcomes for women between 20-40 years old and inhibited the occurrence of newborn defects in both women of the first gestation and women of ≥2 gestations. Conclusions The application of individualized FAS based on gene polymorphisms was more effective in preventing adverse outcomes in the mother and child.

Abstract
BACKGROUND Myocardial ischemia/reperfusion injury (IRI) is a common perioperative complication of heart and great vessels surgery, aggravating the original myocardial damage and seriously affecting the postoperative recovery of cardiac function. The aim of this study was to reveal the functional effects and potential mechanisms of notoginsenoside R1 (NG-R1) in myocardial cells injured by hypoxia-reoxygenation (H/R). METHODS The rat cardiomyocyte line H9c2 was subjected to H/R with or without NG-R1 treatment. The levels of miR-132 and HBEGF in the cell were altered by microRNA or short-hairpin RNA transfection. Cell viability, apoptosis, lactate dehydrogenase (LDH) and malondialdehyde (MDA) were monitored. Dual luciferin was used to detect the relationship between miR-132 and HBEGF. RESULTS NG-R1 (20 μM) had no impact on H9c2 cells, but cell viability was significantly reduced at 80 μM. NG-R1 (20 μM) protected H9c2 cells against H/R-induced cell damage, accompanied by increased cell viability, reduced cell apoptosis, and downregulation of LDH and MDA. Furthermore, the level of miR-132 was decreased in response to H/R exposure but then increased after NG-R1 treatment. When miR-132 was overexpressed, H/R-induced cell damage could be recovered. Downregulation of miR-132 limited the protective effect of NG-R1 on H/R damage. We also found that HBEGF was a direct target of miR-132. The expression of HBEGF was increased upon H/R damage, and this increase was reversed after NG-R1 treatment. CONCLUSIONS This study demonstrated that NG-R1 markedly protected H9c2 cells against H/R-induced damage via upregulation of miR-132 and downregulation of its target protein HBEGF.

Abstract
Reactive oxygen species (ROS) mediate multiple physiological functions; however, the over-accumulation of ROS causes premature aging and/or death and is associated with various inflammatory conditions. Nevertheless, there are limited clinical treatment options that are currently available. The good news is that owing to the considerable advances in nanoscience, multiple types of nanomaterials with unique ROS-scavenging abilities that influence the temporospatial dynamic behaviors of ROS in biological systems have been developed. This has led to the emergence of next-generation nanomaterial-controlled strategies aimed at ameliorating ROS-related inflammatory conditions. Accordingly, herein we reviewed recent progress in research on nanotherapy based on ROS scavenging. The underlying mechanisms of the employed nanomaterials are emphasized. Furthermore, important issues in developing cross-disciplinary nanomedicine-based strategies for ROS-based inflammatory conditions are discussed. Our review of this increasing interdisciplinary field will benefit ongoing studies and clinical applications of nanomedicine based on ROS scavenging.

Abstract
OBJECTIVE In this study, the effect of epithelial cell transformation sequence 2 (ECT2) on the proliferation, invasion and migration of esophageal squamous cell carcinoma (ESCC) was investigated by interfering the expression of ECT2. PATIENTS AND METHODS Interfering with the expression level of ECT2 in human squamous cell carcinomas KYSE140 and EC9706 cell lines, the changes of KYSE140 and EC9706 cell proliferation, invasion, and migration were measured using the CCK-8 method, transwell test, and scratch test, respectively. The effects of ECT2 on the Ras homolog gene family, member A-extracellular regulated protein kinases (RhoA-ERK) signaling pathway were also observed. RESULTS Compared with the control group, the proliferation, migration, and invasion ability of EC9706 and KYSE140 cells after ECT2 knockout were significantly reduced (p <0.05). The knockdown of ECT2 expression in ESCC cell lines suppressed the activation of RhoA-ERK signaling pathway and protein expression of VEGF and MMP9. CONCLUSIONS ECT2 could regulated the expression of VEGF and MMP9 to inhibit cells proliferation, invasion, migration and tumor development through RhoA-ERK signaling pathway. Therefore, ECT2 could be an available marker, and provide a new theoretical basis for the treatment of ESCC.

Abstract
We present the first results of the Fermilab National Accelerator Laboratory (FNAL) Muon g-2 Experiment for the positive muon magnetic anomaly a_{μ}≡(g_{μ}-2)/2. The anomaly is determined from the precision measurements of two angular frequencies. Intensity variation of high-energy positrons from muon decays directly encodes the difference frequency ω_{a} between the spin-precession and cyclotron frequencies for polarized muons in a magnetic storage ring. The storage ring magnetic field is measured using nuclear magnetic resonance probes calibrated in terms of the equivalent proton spin precession frequency ω[over ˜]_{p}^{'} in a spherical water sample at 34.7 °C. The ratio ω_{a}/ω[over ˜]_{p}^{'}, together with known fundamental constants, determines a_{μ}(FNAL)=116 592 040(54)×10^{-11} (0.46 ppm). The result is 3.3 standard deviations greater than the standard model prediction and is in excellent agreement with the previous Brookhaven National Laboratory (BNL) E821 measurement. After combination with previous measurements of both μ^{+} and μ^{-}, the new experimental average of a_{μ}(Exp)=116 592 061(41)×10^{-11} (0.35 ppm) increases the tension between experiment and theory to 4.2 standard deviations.

Abstract
Mulberry leaves are used in traditional Chinese medicine and contain numerous active substances that are known to be beneficial for human health. The aim of this study was to investigate the phenolic compositions and antioxidant activities of the leaves from 23 mulberry cultivars. Qualitative LC-ESI-QTOF analysis revealed the presence of 11 phenolic compounds in the free phenolic extracts and 10 phenolic compounds in the bound fractions. Chlorogenic acid and caffeic acid were the major components in the free and bound fractions, respectively. The results revealed that the changguosang cultivar from Taiwan contained the greatest content of phenolic compounds as well as the highest antioxidant activity among the 23 cultivars examined, as determined using three separate antioxidant assays. The isoquercitrin, chlorogenic acid, and rutin contents of the free phenolic extracts displayed significant correlations with the antioxidant activities, while syringic acid and rutin were the main contributors to the antioxidant activities of the bound phenolic fractions. The obtained results demonstrate that mulberry leaves contain a variety of beneficial phenolic substances and may be suitable for further development as a herbal medicine.

Abstract
Objective: To summarize the experience of perioperative management strategy of fetal pulmonary valvuloplasty (FPV) for hypoplastic right heart syndrome (HRHS). Methods: In the retrospective study of perioperative data, 13 fetuses of HRHS were treated with FPV in Qingdao Women and Children's Hospital from July 2018 to June 2019. Results: (1) The evaluation indexes of the right ventricle in 13 fetuses before FPV: the mean ratio of tricuspid/mitral annulus, right/left ventricular length, pulmonary/aortic annulus, and tricuspid inflow time/cardiac cycle were 0.81±0.04, 0.56±0.14, 0.69±0.06, and 0.35±0.03, respectively. (2) All pregnant mothers underwent general anesthesia. The basic fetal heart rate was (156±12) beats per minutes before FPV, and 9 fetuses showed bradycardia during the operation, and recovered to normal after drug resuscitation. On the first day after FPV, two cases had bradycardia and pregnancy was terminated. The fluctuation of systolic blood pressure of pregnant mother was less than 20%, and there was no significant difference between preoperative and intraoperative pulse pressure [(36.0±5.6) vs (35.8±6.9) mmHg (1 mmHg=0.133 kPa); t=8.102, P=0.951]. (3) All cases of HRHS fetus successfully underwent FPV. The average gestational age was (27.3±0.8) weeks. The average operation time was (23.2±1.0) minutes. The ratio of tricuspid to mitral annulus (t=-2.513, P=0.022) and the ratio of right to left ventricular length (t=-3.373, P=0.003) were significantly improved at 6 weeks postoperatively. Ten fetuses were delivered, and there was no death after early intervention. (4) Of 13 pregnant women, 3 cases were nausea and vomiting on the day of FPV operation, the treatment of the symptoms was improved by tropisetron; one case had tolerable abdominal pain and improved without special treatment. Pregnant women had no major complications such as cardiac failure, abortion and death. (5) Chromosome karyotype analysis and microarray analysis of amniotic fluid was retained during the operation. No typical chromosome abnormality or other abnormal genetic diagnosis was found. Conclusions: FPV colud be used as an effective intervention measure to promote the development of right ventricle in HRHS fetuses. The scientific management of multidisciplinary professional technical team in perioperative period is particularly important to ensure the success of FPV and the safety of pregnant women and fetuses.

Abstract
Mulberry (Morus atropurpurea) is an economically important woody tree and has great potential for the remediation of heavy metals. To investigate how cadmium accumulates and its detoxification in mulberry, we assessed the physiological and transcriptomic effects of cadmium contamination and as well as its chemical forms and subcellular distribution. Cadmium significantly inhibited mulberry plant growth and primarily accumulated in mulberry roots. Antioxidant enzymes were induced by cadmium in all tissues of mulberry. Subcellular fractionation analyses of cadmium indicated that the majority was compartmentalized in soluble fraction in roots while it mainly located in cell wall in leaves and stems. The greatest amount of the cadmium was integrated with proteins and pectates in all mulberry tissues. RNA-seq transcriptomic analyses of mulberry roots revealed that various metabolic pathways involved in cadmium stress response such as RNA regulation, hormone metabolism, and response to stress, secondary metabolism, as well as signaling, protein metabolism, transport, and cell-wall metabolism. These results will increase our understanding of the molecular mechanisms of cadmium detoxification in mulberry and provide new insights into engineering woody plants for phytoremediation.

Abstract
Macrophages are key innate immune cells in the tumor microenvironment that regulate primary tumor growth, vascularization, metastatic spread and response to therapies. Macrophages can polarize into two different states (M1 and M2) with distinct phenotypes and functions. To investigate the known tumoricidal effects of M1 macrophages, we obtained RNA expression profiles and clinical data from The Cancer Genome Atlas Thyroid Cancer (TCGA-THCA). The proportions of immune cells in tumor samples were assessed using CIBERSORT, and weighted gene co-expression network analysis (WGCNA) was used to identify M1 macrophage-related modules. Univariate Cox analysis and LASSO-Cox regression analysis were performed, and four genes (SPP1, DHRS3, SLC11A1, and CFB) with significant differential expression were selected through GEPIA. These four genes can be considered hub genes. The four-gene risk-scoring model may be an independent prognostic factor for THCA patients. The validation cohort and the entire cohort confirmed the results. Univariate and multivariate Cox analysis was performed to identify independent prognostic factors for THCA. Finally, a prognostic nomogram was built based on the entire cohort, and the nomogram combining the risk score and clinical prognostic factors was superior to the nomogram with individual clinical prognostic factors in predicting overall survival. Time-dependent ROC curves and DCA confirmed that the combined nomogram is useful. Gene set enrichment analysis (GSEA) was used to elucidate the potential molecular functions of the high-risk group. Our study identified four genes associated with M1 macrophages and established a prognostic nomogram that predicts overall survival for patients with THCA, which may help determine clinical treatment options for different patients.

Abstract
BACKGROUND Homocysteine (Hcy) has been suggested as an independent risk factor for atherosclerosis. Apolipoprotein M (apoM) is a constituent of the HDL particles. The goal of this study was to examine the serum levels of homocysteine and apoM and to determine whether homocysteine influences apoM synthesis. METHODS Serum levels of apoM and Hcy in 17 hyperhomocysteinemia (HHcy) patients and 19 controls were measured and their correlations were analyzed. Different concentrations of homocysteine (Hcy) and LY294002, a specific phosphoinositide 3- kinase (PI3K) inhibitor, were used to treat HepG2 cells. The mRNA levels were determined by RT-PCR and the apoM protein mass was measured by western blot. RESULTS We found that decreased serum apoM levels corresponded with serum HDL levels in HHcy patients, while the serum apoM levels showed a statistically significant negative correlation with the serum Hcy levels. Moreover, apoM mRNA and protein levels were significantly decreased after the administration of Hcy in HepG2 cells, and this effect could be abolished by addition of LY294002. CONCLUSIONS Present study demonstrates that Hcy downregulates the expression of apoM by mechanisms involving the PI3K signal pathway.

Abstract
Abstract
Introduction
The 2009 Pandemrix influenza A pH1N1 vaccine has been linked to an increased number of Narcolepsy type I onsets in children across Europe whereas administration of a very similar adjuvanted vaccine, Arepanrix, had little effects in Canada. One possible explanation for the difference may be vaccine composition differences that could modify peptide binding to narcolepsy associated HLA-DQ0602 allele, as viral extracts for these two vaccines used distinct processes in different factories. Other explanations may involve differences in vaccination timing in relation to the pandemic H1N1 infection wave, or other environmental factors. We have previously compared the amino acid sequence of the Hemagglutinin (HA) component of the Pandemrix and the 2010 Arepanrix vaccine, finding possible contributors, but excluding most of these after DQ0602-tetramer analysis of T cell reactivity in narcolepsy versus controls.
Methods
Mass spectrometric characterization of multiple additional batches of Pandemrix and Arepanrix used during 2009 influenza pandemic vaccination campaign was performed.
Results
In addition to confirming previously published results such as increased deamidation of hemagglutinin (HA) (146N>D) in Pandemrix (p=2.1e-9), we identified novel differences, including a significant 2-fold post-translation deamidation increase in 277N in Arepanrix versus Pandemrix (p=0.032), together with increased 2-fold glycosylation in the 286-323 positions in Arepanrix (p=0.00036). The 277 N to D/isoD substitution is located in pocket 1 of the binding core of a strong binder NAGSGIIIS, (< 10% rank) for HLA-DQ0602 allele and abolishes epitope binding. The increased glycosylation in Arepanrix occurs in the immediate flanking area of the same 277N epitope and could also reduce DQ0602 presentation of the same epitope through differential binding and/or proteolysis of HA in this region of the molecules. As CD4 T cells recognizing this epitope have been reported to be significantly increased in narcolepsy versus DQ0602 controls, with possible mimicry with homologous hypocretin sequence.
Conclusion
These changes could explain why Arepanrix was less narcolepsy inducing. Confirmatory studies, as well as studies of all novel changes observed, are ongoing, but this is a promising result.

Abstract
Apolipoproteins, the key components of lipoproteins, play vital roles in the combination and transportation of lipids. Numerous research articles have accumulated solid evidence that lipoproteins are closely related to various types of tumorigenesis. In this review, we focused on the associations between several apolipoproteins and breast carcinoma and distinguished the effects and significance of apolipoproteins in different locations to validate their roles in breast carcinoma development. For example, apoD and apoE in serum are viewed as risk factors for breast carcinoma. ApoD, apoE and apoA-I in mammary tissues inhibit tumor growth. Moreover, apoB, apoJ and apoA-I have the potential to function as diagnostic or prognostic markers in the clinic. ApoEdp and apoJ treatment on breast carcinoma could significantly restrict tumor growth. In general, the aim of this review was to further analyze the associations between some members of the apolipoprotein family and breast cancer.

Abstract
Objective: To summarize the experience of arterial duct (AD) stenting in children with ductus-dependent hypoplastic right heart syndrome (HRHS). Methods: Seven children including 4 cases of pulmonary atresia with intact ventricular septum (PA-IVS) with HRHS and 3 cases of critical pulmonary stenosis (CPS)-IVS with HRHS underwent AD stenting in Qingdao Women and Children's Hospital between January 2012 and January 2019. During the same period, 9 patients of PA-IVS with HRHS received Blalock Taussig (B-T) shunt. Two groups of children on the operation time, hospital stay time, intensive care time and mortality were compared.T test or Mann-Whitney U test was used for comparison between the two groups. Results: There was no significant difference in the age (18 (7-100) vs. 17 (1-142) d, U=31.000, P>0.05) and weight ((3.8±1.1) vs. (3.7±1.3) kg, t=0.272, P>0.05) between the AD stenting group and the B-T group.The operation time ((108±7) vs. (160±49) min, t=-4.304), intensive care time ((3.4±1.0) vs. (6.3±4.5) d, t=-8.692) and total hospitalization time ((10.3±1.0) vs. (26.3±1.0) d, t=-7.822) in the AD stenting group were differed significantly compared with the B-T group (all P<0.05). The transcutaneous oxygen saturation improved significantly (0.723±0.125 vs. 0.926±0.005, t=-6.044, P<0.05) after AD stenting. The diameter of AD stent ranged from 3.5 to 4.0 mm, and the length of AD stent was 16-21 mm. There were no complications such as vascular injury, acute thrombus, catheter spasm and death in the AD stenting group. The mortality of children in the B-T group was 3 in 9 cases. Three cases in the AD stenting group received pulmonary valvulotomy and bilateral Glenn operation at 6, 9 and 9 months after AD stenting, respectively. Conclusions: AD stenting is a feasible, effective, safe and minimally invasive procedure for children with ductus-dependent HRHS. It can even be used as an alternative to B-T shunt.

An international collaborative study was conducted of a high-performance liquid chromatography (HPLC)-UV method for the determination of the major (ephedrine [EP] and pseudoephedrine [PS]) and minor (norephedrine [NE], norpseudoephedrine [NP], methylephedrine [ME], and methylpseudoephedrine [MP]) alkaloids in selected dietary supplements representative of the commercially available products. Ten collaborating laboratories determined the ephedrine-type alkaloid content in 8 blind replicate samples. Five products contained ephedra ground herb or ephedra extract. These 5 products included ground botanical raw material of Ephedra sinica, a common powdered extract of Ephedra sinica, a finished product containing only Ephedra sinica ground botanical raw material, a complex multicomponent dietary supplement containing Ma Huang, and a high-protein chocolate flavored drink mix containing Ma Huang extract. In addition, collaborating laboratories received a negative control and negative control spiked with ephedrine alkaloids at high and low levels for recovery studies. Test extracts were treated to solid-phase extraction using a strong-cation exchange column to help remove interferences. The HPLC analyses were performed on a polar-embedded phenyl column using UV detection at 210 nm. Repeatability relative standard deviations (RSD r) ranged from 0.64–3.0% for EP and 2.0–6.6% for PS, excluding the high protein drink mix. Reproducibility relative standard deviations (RSD R) ranged from 2.1–6.6% for EP and 9.0–11.4% for PS, excluding the high protein drink mix. Recoveries ranged from 84.7–87.2% for EP and 84.6–98.2% for PS. The data developed for the minor alkaloids are more variable with generally unsatisfactory HORRATS (i.e., >2). However, since these alkaloids generally add little to the total alkaloid content of the products, the method gives satisfactory results in measuring total alkaloid content (RSD r 0.85–3.13%; RSDR 2.03–10.97%, HORRAT 0.69–3.23, exclusive of the results from the high protein drink). On the basis of these results, the method is recommended for Official First Action for determination of EP and PS in dietary supplements exclusive of the high protein drinks.

Abstract
A collaborative study was conducted to evaluate the accuracy and precision of a method for ephedrine-type alkaloids (i.e., norephedrine, norpseudoephedrine, ephedrine, pseudoephedrine, methylephedrine, and methylpseudoephedrine) in human urine and plasma. The amount of ephedrine-type alkaloids present was determined using liquid chromatography (LC) with tandem mass selective detection. The test samples were diluted to reflect a concentration of 5.00–100 ng/mL for each alkaloid. An internal standard was added and the alkaloids were separated using a 5 μm phenyl LC column with an ammonium acetate, glacial acetic acid, acetonitrile, and water mobile phase. Eight blind duplicates of human urine and eight blind duplicates of human plasma were analyzed by 10 collaborators. In addition to negative controls, test portions of urine and plasma were fortified at 3 different levels with each of the 6 ephedrine-type alkaloids at approximately 1, 2, and 5 μg/mL for urine and 100, 200, and 500 ng/mL for plasma. On the basis of the accuracy and precision results for this collaborative study, it is recommended that this method be adopted Official First Action for the determination of 6 different ephedrine-type alkaloids in human urine and plasma.

Abstract
An interlaboratory study was conducted to evaluate the accuracy and precision of a method for ephedrine-type alkaloids [i.e., norephedrine (NE), norpseudoephedrine (NPE), ephedrine (E), pseudoephedrine (PE), methylephedrine (ME), and methylpseudoephedrine (MPE)] in dietary supplements and botanicals. The amount of ephedrine-type alkaloids present was determined using liquid chromatography with tandem mass selective detection. The samples were diluted to reflect a concentration of 0.0200 to 1.00 μg/mL for each alkaloid. An internal standard was added and the alkaloids were separated using a 5 μm phenyl LC column with an ammonium acetate, glacial acetic acid, acetonitrile, and water mobile phase. Eight blind duplicates of dietary supplements or botanicals were analyzed by 10 collaborators. Included was a negative control, ephedra nevadensis, and negative controls fortified at 2 different levels with each of the 6 ephedrine-type alkaloids. The spike levels were approximately 100 and 1000 μg/g for NE, 100 and 600 μg/g for NPE, 6500 and 65 000 μg/g for E, 1000 and 10 000 μg/g for PE, 300 and 3000 μg/g for ME, and 100 and 1000 μg/g for MPE. On the basis of the accuracy and precision results for this interlaboratory study, it is recommended that this method be adopted Official First Action for the determination of 6 different individual ephedrine-type alkaloids in dietary supplements and botanicals.

Abstract
Objective: To evaluate the mid-term outcomes of coronary artery bypass grafting (CABG) with left radial artery (RA) graft bypassed to right main coronary artery (RCA) of severe stenosis. Methods: Between September 2014 and April 2019, a total of consecutive 47 patients who had severe stenosis (≥90%) of RCA underwent total arterial revascularization, with left RA bypassed to RCA. There were 31 males and 16 females, with a mean age of (56.5±9.7) years old. The perioperative outcomes were observed and mid-term results were followed up. Results: A total of 46 left internal mammary artery (LIMA) grafts, 47 left radial artery (LRA), and 40 right RA grafts (RRA) were harvested with pedicles. LIMA was bypassed to LAD in 43 patients, RRA was to diagonal branches, ramus or oblique marginal in 37 cases, and LRA was to RCA. All grafts (except 3 composite Y or T grafts) were single. Mean graft number was 2-4 (2.7±0.9). There was one death due to cardiac tamponade. Three patients had postoperative atrial fibrillation, 1 had a forearm hematoma, 1 had acute renal insufficiency, and 2 had acute myocardial infarction. The mean tracheal intubation duration was 3.5-20.3 (8.3±4.7) hours, and the mean hospital stay was 6-13 (7.1±2.9) days. The average follow-up was 3-47 (23.3±7.5) months, with a follow-up rate of 86.96% (40/46). There were no major cardiovascular events during the follow-up. Three month after surgery, the mean left ventricular ejection fraction was significantly improved than that of pre-operation (60.0%±4.0% vs 42.4%±7.5%, P=0.003). Computed tomography angiography (CTA) examination showed that 58.7% (27/46) of patients had patent LRA after a mean follow-up duration of (19.5±7.3) months. Conclusion: CABG with LRA bypassed to RCA of severe stenosis proves to be safe and effective, with good mid-term outcomes.

Abstract
Malignant glioma is the most common and aggressive primary brain tumor and the overall prognosis for glioma patients remains poor. Clarification of the molecular mechanism responsible for glioma progression is critical for the effective treatment of glioma. Melanoma antigen gene (MAGE)-A2 (MAGEA2) is a member of the MAGE-A family proteins widely studied for cancer vaccine development and identification of tumor markers. However, MAGEA2 clinical significance and biological function in glioma remain unclear, especially for the prognosis of glioma patients. This study investigates MAGEA2 expression in glioma tissue samples and its significance in predicting glioma patient prognosis. MAGEA2 protein expression in tissue samples was measured by immunohistochemistry and western blotting, and MAGEA2 mRNA expression was determined by real-time polymerase chain reaction. Our results confirmed that MAGEA2 mRNA and protein expression levels were upregulated in glioma tissues, compared with normal brain tissue. The high expression of MAGEA2 in glioma tissues significantly correlated with World Health Organization advanced grade. Univariate and multivariate analyses revealed that high MAGEA2 expression is an independent prognostic factor for glioma patient poor overall survival. The P53 mRNA expression levels were downregulated in glioma tissues compared to noncancerous brain tissue and MAGEA2 expression negatively correlated with P53 expression. Taken together, our results suggest that MAGEA2 plays an oncogenic role in glioma progression, and they provide insight into MAGEA2 application as a novel predictor of clinical outcomes and a potential glioma biomarker.
