Abstract
Understanding the dynamics of neurotransmitters is crucial for unraveling synaptic transmission mechanisms in neuroscience. In this study, we investigated the impact of terahertz (THz) waves on the aggregation of four common neurotransmitters through all-atom molecular dynamics (MD) simulations. The simulations revealed enhanced nicotine (NCT) aggregation under 11.05 and 21.44 THz, with a minimal effect at 42.55 THz. Structural analysis further indicated strengthened intermolecular interactions and weakened hydration effects under specific THz stimulation. In addition, enhanced aggregation was observed at stronger field strengths, particularly at 21.44 THz. Furthermore, similar investigations on epinephrine (EPI), 5-hydroxytryptamine (5-HT), and γ-aminobutyric acid (GABA) corroborated these findings. Notably, EPI showed increased aggregation at 19.05 THz, emphasizing the influence of vibrational modes on aggregation. However, 5-HT and GABA, with charged or hydrophilic functional groups, exhibited minimal aggregation under THz stimulation. The present study sheds some light on neurotransmitter responses to THz waves, offering implications for neuroscience and interdisciplinary applications.

Abstract
Objective: To explore the diagnosis and treatment of adolescence-onset methylenetetrahydrofolate reductase (MTHFR) deficiency. Methods: This was a retrospective case study. Nine patients with adolescence-onset MTHFR deficiency were diagnosed at Peking University First Hospital from January 2016 to December 2022, and followed up for more than 1 year. Their general information, clinical manifestations, laboratory tests, cranial images, MTHFR gene variants, diagnosis, treatment, and outcome were analyzed retrospectively. Results: The 9 patients came from 8 families. They had symptoms at age of 8.0 years to 17.0 years and diagnosed at 9.0 years to 17.5 years. Eight were male and 1 was female. Two patients were brothers, the elder brother developed abnormal gait at 17.0 years; and the younger brother was then diagnosed at 15.0 years of age and treated at the asymptomatic stage, who was 18.0 years old with normal condition during this study. The main manifestations of the 8 symptomatic patients included progressive dyskinesia and spastic paralysis of the lower limbs, with or without intellectual decline, cognitive impairment and behavioral abnormalities. Totally, 15 variants of MTHFR gene were identified in the 9 patients, including 8 novel variants. Five patients had brain image abnormalities. Increased plasma total homocysteine level (65-221 μmol/L) was found in all patients, and decreased to 20-70 μmol/L after treatment with betaine and calcium folinate. Besides, the 8 symptomatic patients had their behavior and cognitive problems significantly improved, with a legacy of lower limb motor disorders. Conclusions: Late-onset MTHFR deficiency can occur in adolescence. The diagnosis is usually delayed because of non-specific clinical symptoms. The test of blood total homocysteine could be used as a selective screening test. Eight novel varients of MTHFR gene were identified. Timely treatment can improve clinical condition significantly, and pre-symptomatic treatment may prevent brain damage.

Abstract
Background The most common disorder of the intracellular cobalamin metabolism pathway is the combined methylmalonic acidemia and homocysteinemia, cblC type (cblC). There is a variation in its clinical spectrum ranging from severe neonatal-onset forms that are highly fatal to later-onset forms which are milder. In this study, the first case of an asymptomatic Chinese woman with a defect in congenital cobalamin (cblC type) metabolism at prenatal diagnosis due to elevated homocysteine level is identified. Case presentation The proband, a male child born to a 29-year-old G1P0 mother, admitted to local hospital with feeding disorder, intellectual disability, seizures, microcephaly, as well as heterophthalmos. The level of the urine methylmalonic was elevated. Equally found were increased blood propionylcarnitine (C3) and propionylcarnitine/free carnitine ratio (C3/C0) and decreased methionine levels. The plasma total homocysteine level was elevated at 101.04 μmol/L (normal < 15 μmol/L). The clinical diagnosis of combined methylmalonic acidemia and homocysteinemia was supported. Four years later, the mother of the boy married again and came to us for prenatal diagnosis exactly 15 weeks after her last menstrual period. Subsequently, there is an increase in the amniotic fluid methylmalonate. The level of the amniotic fluid total homocysteine was marginally high. A considerably elevated amniotic fluid C3 was equally observed. In addition, there is a respective significant increase in the plasma and urine total homocysteine at 31.96 and 39.35 μmol/L. After the sequencing of MMACHC genes, it is found that the boy, a proband carried a homozygous mutation of the MMACHC at c.658_660delAAG. While the boy's mother, she carries two mutations in MMACHC: c.658_660delAAG and c.617G>A. The fetus is a carrier of the MMACHC gene. Following the administration of routine treatment, the mother remained symptom-free in the course of pregnancy, and she gave birth to a healthy boy. Conclusion Variable and nonspecific symptoms characterized the cblC type of methylmalonic acidemia combined with homocysteinemia. Both biochemical assays and mutation analysis are recommended as crucial complementary techniques.

Abstract
Objective: Propionic acidemia is a rare inherited metabolic disorder caused by propionyl CoA carboxylase (PCC) deficiency. This study aims to analyze the clinical characteristics and gene variations of Chinese patients with propionic acidemia, and to explore the correlation between clinical phenotypes and genotypes. Methods: Single-center, retrospective and observational study. Seventy-eight patients of propionic acidemia (46 males and 32 females) from 20 provinces and autonomous regions were admitted from January 2007 to April 2022. Their age of initial diagnosis ranged from 7 days to 15 years. The clinical manifestations, biochemical and metabolic abnormalities, genetic variations, diagnosis, treatment and outcome were studied. Chi-Square test or Mann-Whitney U test were used for statistical analysis. Results: Among 78 cases, 6 (7.7%) were identified by newborn screening; 72 (92.3%) were clinically diagnosed after onset, and the age of onset was 2 hours after birth to 15 years old; 32 cases had early-onset disease and 40 cases had late-onset disease. The initial manifestations included lethargy, hypotonia, vomiting, feeding difficulties, developmental delay, epilepsy, and coma. Among the 74 cases who accepted gene analysis, 35 (47.3%) had PCCA variants and 39 (52.7%) had PCCB variants. A total of 39 PCCA variants and 32 PCCB variants were detected, among which c.2002G>A and c.229C>T in PCCA and c.838dupC and c.1087T>C in PCCB were the most common variants in this cohort. The variants c.1228C>T and c.1283C>T in PCCB may be related to early-onset type. The variants c.838dupC, c.1127G>T and c.1316A>G in PCCB, and c.2002G>A in PCCA may be related to late-onset disease. Six patients detected by newborn screening and treated at asymptomatic stage developed normal. The clinically diagnosed 72 cases had varied complications. 10 (12.8%) cases of them died. 62 patients improved after metabolic therapy by L-carnitine and diet. Six patients received liver transplantation because of recurrent metabolic crisis. Their clinical symptoms were markedly improved. Conclusion: The clinical manifestations of propionic acidemia are complex and lack of specificity. Newborn screening and high-risk screening are keys for early treatment and better outcome. The correlation between the genotype and phenotype of propionic acidemia is unclear, but certain variants may be associated with early-onset or late-onset propionic acidemia.

Abstract
Objective: To analyze the clinical features and CBS gene variants of 13 patients with classic homocystinuria, and the strategies of individual treatment and prevention were explored. Methods: The general information, clinical manifestations, laboratory tests, cranial images, CBS gene variants, diagnosis and therapeutic strategies of 13 patients with classic homocystinuria admitted to the Department of Pediatrics of Children's Hospital Affiliated to Zhengzhou University and Peking University First Hospital from November 2013 to June 2021 were analyzed retrospectively. Results: There were 13 patients diagnosed at the age of 10 days to 14 years, 6 were male and 7 were female. There were 3 patients detected by newborn screening and received treatment at the asymptomatic stage. There were 10 patients clinically diagnosed at the age of 5 to 14 years. Their symptoms appeared at age of 1 to 6 years. The major clinical manifestations were marfanoid features, lens dislocation and (or) myopia, developmental delay, osteoporosis, and cardiovascular diseases. Brain magnetic resonance imaging showed asymmetric infarcts in 4 patients and hypomyelination in 1 case. Increased blood methionine, plasma total homocysteine and urinary total homocysteine with normal urinary methylmalonic acid were found in 13 patients. The biochemical features were consistent with classic homocystinuria. Totally 18 variants were identified in CBS gene of 13 patients, 10 variants were novel and 8 were reported. only 1 patient was partially responsive to vitamin B6 treatment, while 12 cases were non-responsive. They were mainly treated with low methionine diet and betaine supplement. Three vitamin B6 non-responsive cases received liver transplantation at age of 3, 8 and 8 years, respectively. Their blood methionine and total homocysteine returned to normal within a week after liver transplantation. One patient died. Prenatal diagnosis was performed for a fetus when the mother was pregnant again. Two pathogenic CBS gene variants were identified from the amniocytes as same as the proband. Conclusions: The clinical manifestations of classic homocystinuria are complex and variable. Blood amino acid analysis, serum or urine total homocysteine assay and gene analysis are critical for its diagnosis. There were 10 novel CBS gene varients were identified expanding the CBS gene varient spectrum. Liver transplantation is an effective treatment. Prenatal diagnosis is important to prevent classic homocysteinuria.

Abstract
Objective: To assess the association of genetic polymorphisms and circulating levels of chemokine monocyte chemoattractant protein-1 (MCP1) with risk of breast cancer. Methods: A total of 820 patients with pathologically confirmed breast cancer and 900 age-and area-of-residence-matched healthy controls who visited the hospital for routine health screening during the same period were included in this case-control study. Mendelian randomization analysis was performed using three widely followed functional single nucleotide polymorphisms (SNPs) of the MCP1 gene rs1024611, rs2857656 and rs4586 to construct instrumental variables. Results: MCP1 rs1024611 (OR=1.26, P=0.002), rs2857656 (OR=1.23, P=0.006) and rs4586 (OR=1.23, P=0.003) were significantly associated with increased risk of breast cancer. SNP rs1024611 (β=1.194, P<0.001), rs2857656 (β=1.221, P<0.001) and rs4586 (β=1.137, P<0.001) were positively correlated with higher circulating level of MCP1. The case-control study showed that an increase of 23.7 pg/ml of circulating levels of MCP1 was associated with a 0.25-fold increased risk of breast cancer. MR analysis confirmed that the genetic predicted circulating levels of MCP1 were associated with an increased risk of breast cancer, and the risk of breast cancer increased by 0.20 times with an increase of 23.7 pg/ml in MCP1. Conclusion: Genetic variants and circulating levels of MCP1 are significantly associated with the risk of breast cancer and can be used as a biomarker for early prediction of breast cancer.

Abstract
As a common soil-borne nematode, hookworm is mainly parasitized in the intestine, and the clinical manifestations of hookworm infections mainly include gastrointestinal symptoms and iron-deficiency anemia. In addition, hookworm may be also parasitized in other organs in addition to gastrointestinal system, resulting in development of disorders in other systems. Proteinuria caused by hookworm infections is rare and easy to be misdiagnosed in clinical practices. Hereby, the diagnosis and treatment of a case of proteinuria associated with hookworm infections was reported, in order to increase the understanding of hookworm infection-associated proteinuria among clinicians.

Abstract
Objective: To analyze the clinical features, genetic characteristics, treatment and follow-up results of patients with hydrocephalus caused by methylmalonic acidemia combined with homocysteinuria, and to discuss the optimal strategies for assessing and treating such patients. Methods: From January 1998 to December 2020, 76 patients with hydrocephalus due to methylmalonic acidemia combined with homocysteinuria in the Department of Pediatrics in 11 hospitals including Peking University First Hospital were diagnosed by biochemical, genetic analysis and brain imaging examination. The patients were divided into operation-group and non-operation-group according to whether they underwent ventriculoperitoneal shunt. The clinical features, laboratory examinations, genotype, and follow-up data were retrospectively analyzed. Data were compared between the two groups using rank sum test, and categorical data were compared using χ2 test. Results: Among the 76 patients (51 male, 25 female), 5 were detected by newborn screening, while 71 were diagnosed after clinical onset, 68 cases (96%) had early-onset, 3 cases (4%) had late-onset. The most common clinical manifestations of 74 cases with complete data were psychomotor retardation in 74 cases (100%), visual impairment in 74 cases (100%), epilepsy in 44 cases (59%), anemia in 31 cases (42%), hypotonia or hypertonia in 21 cases (28%), feeding difficulties in 19 cases (26%) and disturbance of consciousness in 17 cases (23%). Genetic analysis was performed in 76 cases, all of whom had MMACHC gene variations, including 30 homozygous variations of MMACHC c.609G>A. The most common variations were c.609G>A (94, 62.7%), followed by c.658_660del (18, 12.0%), c.567dupT (9, 6.0%) and c.217C>T (8, 5.3%). Therapy including cobalamin intramuscular injection, L-carnitine and betaine were initiated immediately after diagnosis. A ventriculoperitoneal shunt operation was performed in 41 cases (operation group), and 31 patients improved after metabolic intervention (non-operation group). There was no significant difference in the age of onset, the age of diagnosis, the blood total homocysteine, methionine, and urinary methylmalonic acid concentration between the two groups (all P>0.05). The symptoms of psychomotor development, epilepsy, and visual impairments improved gradually after a long-term follow-up in the operation group. Conclusions: Hydrocephalus is a severe complication of methylmalonic acidemia combined with homocysteinuria. The most common clinical manifestations are psychomotor retardation, visual impairment, and epilepsy. It usually occurs in early-onset patients. Early diagnosis and etiological treatment are very important. Hydrocephalus may improve after metabolic intervention in some patients. For patients with severe ventricular dilatation, prompt surgical intervention can improve the prognosis.

Abstract
Objectives: To summarize the clinical and genetic characteristics of the patients with isolated methylmalonic acidemia and investigate the strategies for the diagnosis, treatment and prevention. Methods: Three hundred and fourteen patients (180 males, 134 females) with isolated methylmalonic acidemia were ascertained from 26 provinces or cities across the mainland of China during January 1998 to March 2020. Genetic analysis was performed by Sanger sequencing, gene panel sequencing, whole exome sequencing, multiplex ligation-dependent probe amplification or quantitative PCR. According to the age of onset, the patients were divided to early-onset group (≤12 months of age) and the late-onset group (>12 months of age). They were treated by cobalamin, L-carnitine and (or) special diet and symptomatic treatment. Statistical analysis was done using Chi-square test. Results: Fifty-eight of 314 (18.5%) patients were detected by Newborn screening using liquid chromatography tandem mass spectrometry. Five cases (1.6%) had a postmortem diagnosis. Two hundred and fifty-one patients (79.9%) were clinically diagnosed with an age of onset ranged from 3 hours after birth to 18 years. One hundred and fifty-nine patients (71.0%) belonged to early-onset groups, 65 patients (29.0%) belonged to the late-onset group. The most common symptoms were metabolic crises, psychomotor retardation, epilepsy, anemia and multiple organ damage. Metabolic acidosis and anemia were more common in early-onset patients than that in late-onset patients (20.8%(33/159) vs. 9.2% (6/65), 34.6% (55/159) vs. 16.9% (11/165), χ(2)=4.261, 6.930, P=0.039, 0.008). Genetic tests were performed for 236 patients (75.2%), 96.2%(227/236) had molecular confirmation. One hundred and twenty-seven variants were identified in seven genes (MMUT, MMAA, MMAB, MMADHC, SUCLG1, SUCLA2, and MCEE), of which 49 were novel. The mut type, caused by the deficiency of methylmalonyl-CoA mutase, was the most common (n=211, 93%) cause of this condition. c.729_730insTT, c.1106G>A and c.914T>C were the three most frequent mutations in MMUT gene. The frequency of c.914T>C in early-onset patients was significantly higher than that in late-onset patients (8.3% (18/216) vs. 1.6% (1/64), χ(2)=3.859, P=0.037). Metabolic crisis was more frequent in mut type than the other types (72.6% (114/157) vs. 3/13, χ(2)=13.729, P=0.001),developmental delay and hypotonia were less frequent in mut type (38.2% (60/157) vs. 9/13, 25.5% (40/157) vs. 8/13, χ(2)=4.789, 7.705, P=0.030, 0.006). Of the 58 patients identified by newborn screening, 44 patients (75.9%) who were treated from asymptomatic phase developed normally whereas 14 patients (24.1%) who received treatment after developing symptoms exhibited varying degrees of psychomotor retardation. Conclusions: The characteristics of phenotypes and genotypes among Chinese patients with isolated methylmalonic acidemia were analyzed. Expanded the mutation spectrum of the associated genes. Because of the complex clinical manifestations and severe early onset of isolated methylmalonic acidemia, Newborn screening is crucial for early diagnosis and improvement of prognosis. MMUT gene is recommended for carrier screening as an effort to move the test earlier as a part of the primary prevention of birth defects.

Abstract
The patients with spinal cord injury (SCI) suffered significantly higher risk of deep vein thrombosis (DVT) than normal population. The aim was to assess the clinical significance of macrophage migration inhibitory factor (MIF) as the risk factor for DVT in acute SCI patients. 207 Chinese patients were enrolled in this study, including thirty-nine (39) patients (18.8 %; 95 %CI: 13.5 %–24.2 %) diagnosed as DVT at the follow-up of 1 month. Nine (9) of the 39 patients (23.1%) were suspected of thrombosis before the screening. The MIF levels in plasma of DVT patients were significantly higher than DVT-free patients. The risks of DVT would be increased by 11 % (OR unadjusted: 1.11; 95% CI, 1.06–1.17, P<0.001) and 8 % (OR adjusted: 1.08; 1.03–1.14, P=0.001), for each additional 1 ng/ml of MIF level. Furthermore, after MIF was combined with established risk factors, area under the receiver operating characteristic curve (standard error) was increased from 0.82(0.035) to 0.85(0.030). The results showed the potential association between the high MIF levels in plasma and elevated DVT risk in SCI patients, which may assist on early intervention.

Abstract
Objective: To examine the overall status of the Jiangsu Province Coronary Artery Bypass Grafting Registry database. Methods: The patients date of Jiangsu Province Coronary Artery Bypass Grafting Registry database from October 2017 to December 2019 was collected retrospectively.Risk factors, history, cardiac function (New York Heart Association class), extent of coronary artery lesion, European system for cardiac operative risk evaluation Ⅱ (EuroSCORE Ⅱ), cardiopulmonary bypss, arterial grafts, the numbers and flow of grafts and postoperative major adverse cardiac and cerebrovascular event(MACCE) information were analyzed. The clinical data of patients underwent on-pump CABG(ONCABG) or off-pump CABG (OPCAB) were compared by t test or χ(2) test. Results: Up till December 2019, the database enrolled 7 138 patients, in which 4 661 patients receiving primary isolated CABG. There were 3 486 males and 1 175 females with the age of (64.6±8.1) years (range:31 to 87 years). There were coronary left main disease in 960 patients, triple vessel disease in 3 934 patients, both left main and triple vessel disease in 837 patients, ejection fraction>50% in 3 841 patients, cardiac function class Ⅲ to Ⅳ in 1 664 patients. EuroSCORE Ⅱ was (2.3±0.7)% (range: 0.5% to 35.8%). There were 2 731 patients (58.59%) underwent ONCABG and 1 930 patients (41.41%) underwent OPCAB. There were 4 144 patients (88.91%) for whom the left internal thoracic artery was harvested. Seven centers (2 centers routinely) used left radial artery, 5 centers (3 centers routinely) used the transit time flow meter. The graft was 3.4±0.7 (range:1 to 7), the aortic crossclamp time was (65.0±20.4) minutes (range: 21 to 196 minutes), the cardiopulmonary bypass time was (90.0±24.2) minutes (range: 33 to 227 minutes). In-hospital death ocurred in 84 patients(1.80%), while re-operation in 93 patients (2.00%), myocardial infarction in 71 patients (1.52%), cerebral infarction in 33 patients (0.71%) and dialysis in 56 patients (1.20%). There were 2 936 patients prescribed with secondary prevention drugs(62.99%).Comparing with OPCAB group, ONCABG group had younger age, more female, more diabetes mellitus, more history of myocardial infarction and percutaneous transluminal coronary angioplasty, poorer cardiac function and coronary lesions, higher EuroSCORE Ⅱ, preoperatively (all P<0.05), and was associated with higher MACCE (135/2 731 vs. 71/1 930, χ(2)=4.280, P=0.039), and of more grafts, transfusion and intra-aortic balloon counterpulsation application (all P<0.05). Conclusions: Jiangsu Province Coronary Artery Bypass Grafting Registry database is generally in good operation, and some parameters still need to be improved. Comparing with OPCAB group, ONCABG has more severe preoperative general conditions, while the outcomes is acceptable.

Abstract
2,2',4,4'-Tetrabromodiphenyl ether (BDE-47) is associated with various adverse human health effects; however, the knowledge of its toxicity is still very limited. Mitochondrial injury has been observed in liver cells exposed to BDE-47 in vitro. Mitophagy impairment causes the accumulation of dysfunctional mitochondria, contributing to the pathological mechanisms of liver injury. The aim of this study was to investigate whether BDE-47 impairs mitophagy to trigger mitochondrial dysfunction-related liver injury and the underlying mechanisms. This study revealed that BDE-47 elicited mitochondrial dysfunction and related oxidative liver injury by impairing mitophagy. Moreover, our results showed that NAD+ insufficiency is responsible for BDE-47-mediated mitophagy defect and mitochondrial dysfunction in mouse livers, which was associated with suppression of Sirt3/FoxO3a/PINK1 signaling. Furthermore, our results indicated a potential role of miR-34a-5p in the hepatotoxicity of BDE-47. Mechanistically, BDE-47 dramatically upregulated miR-34a-5p expression in mouse livers. The data from AAV-sponge-mediated miR-34a-5p inhibition suggested that miR-34a-5p diminished NAD+ level by directly targeting NAMPT expression in BDE-47-treated mouse livers, which was confirmed by luciferase reporter assay. Consequently, miR-34a-5p markedly abated Sirt3/FoxO3a/PINK1 signaling-mediated mitophagy to promote mitochondrial dysfunction in BDE-47-treated mouse livers. The present study provided in vivo evidence to reveal a potential mechanism for BDE-47-induced mitochondrial dysfunction and related liver injury and indicated that miR-34a-5p-mediated mitophagy impairment might be a therapeutic target for BDE-47 toxicity.

Abstract
AB209371 gene has been characterized as an oncogenic lncRNA in liver cancer. However, its involvement in ovarian carcinoma (OC) is unknown. In the present study, we analyzed the roles of AB209371 in OC. We found that AB209371 gene and Survivin gene were up-regulated in OC and positively correlated with OC development. AB209371 over-expression led to up-regulated Survivin in OC cells, while Survivin over-expression failed to affect AB209371. In addition, AB209371 over-expression led to down-regulated miR-203. However, miR-203 over-expression failed to affect AB209371, but down-regulated the expression of Survivin. In addition, over-expressions of AB209371 and Survivin resulted in the increased proliferation rate of OC cells. Over-expression MiR-203 played the opposite role and attenuated the effects of AB209371 over-expression. Therefore, AB209371 may down-regulate miR-203 to up-regulate Survivin, thereby promoting OC cell proliferation. Our study provided novel insights into the pathogenesis of OC.

Abstract
Long non-coding RNAs (lncRNAs) are an emerging class of RNA species that may play a critical regulatory role in gene expression. However, the association between lncRNAs and atrial fibrillation (AF) is still not fully understood. In this study, we used RNA sequencing data to identify and quantify the both protein coding genes (PCGs) and lncRNAs. The high enrichment of these up-regulated genes in biological functions concerning response to virus and inflammatory response suggested that chronic viral infection may lead to activated inflammatory pathways, thereby alter the electrophysiology, structure, and autonomic remodeling of the atria. In contrast, the downregulated GO terms were related to the response to saccharides. To identify key lncRNAs involved in AF, we predicted lncRNAs regulating expression of the adjacent PCGs, and characterized biological function of the dysregulated lncRNAs. We found that two lncRNAs, ETF1P2, and AP001053.11, could interact with protein-coding genes (PCGs), which were implicated in AF. In conclusion, we identified key PCGs and lncRNAs, which may be implicated in AF, which not only improves our understanding of the roles of lncRNAs in AF, but also provides potentially functional lncRNAs for AF researchers.

Abstract
Long noncoding RNAs, including HOTAIR, are involved in the pathogenesis of a wide range of diseases. This study aimed to explore the mechanism underlying the involvement of HOTAIR in neonatal bronchial hyperresponsiveness (BHR). A total of 105 newborns were recruited in this study to collect their peripheral blood mononuclear cell and serum samples, which were then divided into different genotype groups based on the genotypes of rs4759314, rs874945, and rs7958904. The real-time polymerase chain reaction, western blot analysis, computational analyses, and luciferase assays were performed to establish the regulatory relationships between the HOTAIR, microRNA-126 (miR-126), and interleukin-13 (IL-13). The level of HOTAIR, miR-126, and IL-13 among rs4759314 AA, AG, and GG groups, as well as among rs874945 GG, AG, and AA groups was similar. However, the level of HOTAIR was increased in the rs7958904 GG group, accompanied by a decreased level of miR-126 and IL-13. In addition, the level of airway responsiveness was comparable among rs4759314 AA, AG, and GG groups, as well as among rs874945 GG, AG, and AA groups. However, the airway responsiveness in the groups rs7958904 CG and CC was much stronger than that of the GG group. We also demonstrated that, by directly binding to miR-126, HOTAIR reduced the expression of miR-126, which in turn decreased the expression of IL-13. In summary, we demonstrated the role of HOTAIR-induced downregulation of miR-126 and IL-13 in the development of BHR in neonates.

Abstract
Breast cancer is one of the most prevalent and fatal diseases around the world. The mechanism of tumorigenesis in breast cancer remains to be clarified. miR-421 plays an oncogenic role in many cancers. Although, the clinical significance of miR-421 in patients with breast cancer is still to be investigated. Caspase-10 is one of the initiator of apoptosis. But the relationship between miR-421 and caspase-10 has not been investigated. In the present study, we found that miR-421 was expressed much higher in breast cancer tissues compared to those in adjacent non-tumor tissues. Furthermore, miR-421 promotes cell proliferation and colony formation in vitro. miR-421 inhibits cell apoptosis probably through restraining caspase-10 expression. Thus, miR-421 might be a potential diagnostic maker and therapeutic target for breast cancer.

Abstract
Due to the insufficient use of local information, the traditional fuzzy C-means (FCM) algorithm and its extension algorithm combined with spatial information show poor robustness and low segmentation accuracy. In addition, in the process of image segmentation based on the FCM algorithm, the initial center estimation is regarded as the process of searching the appropriate value in the gray range. To solve these problems, a new robust algorithm is proposed in this paper. The algorithm searches the optimal initial center by introducing an improved parallel Lévy grey wolf optimization algorithm, which is an improved fuzzy C-means segmentation algorithm that combines local information and adaptive gray weighting. Experimental results infer that both the precision and efficiency of the proposed method are superior to those of the state-of-arts.

Abstract
OBJECTIVE Omentin-1, an adipokine released from visceral fat tissue, is associated with diabetes and stroke. The purpose of this study was to assess the impact of serum omentin-1 levels on functional prognosis in nondiabetic patients with ischemic stroke. METHODS From March 2016 to December 2017, consecutive patients with first-ever ischemic stroke admitted to our hospital, China, were recorded. Functional impairment was evaluated at 3-month after admission using the modified Rankin scale (mRS). Uni-and multivariate analyses with Cox proportional hazard regression was used for assessing the relationship between serum level of omentin-1 and functional outcome. RESULTS We recorded 209 stroke patients, 52 of them (24.9%) experienced as poor functional outcome. The obtained omentin-1 level in patients with poor outcome was lower than in those patients with good outcome [100.8 (80.9-131.6) ng/ml vs. 137.6 (IQR, 106.1-171.5) ng/ml; Z=4.692; P<0.001). Multivariate analysis models were used to assess stroke outcome according to omentin-1 quartiles (the highest quartile [Q4] as the reference), the 1st and 2nd quartile of omentin-1 were compared against the Q4, and the risks were increased by 505% (HR=6.05; 95% CI: 2.13-12.15; P=0.007) and 215% (31.5; 1.21-7.98; P=0.03), respectively. The inclusion of omentin-1 in the routine prediction model for the prediction of poor functional outcome, enhanced the NRI (P=0.006) and IDI (P=0.001) values, confirming the effective reclassification and discrimination. Kaplan-Meier analysis suggested that the patients with low serum omentin-1 levels had a higher risk of death than those patients with high levels of omentin-1 (log-rank test P=0.033). CONCLUSION In this cohort of nondiabetic patients with ischemic stroke, a reduced baseline level of serum omentin-1 was related with an increased risk for poor functional outcome or death, independent of baseline variables.

Abstract
Pancreatic cancer is a lethal malignancy with relatively few effective therapies. Recent investigations have highlighted the role of microRNAs (miRNAs) as crucial regulators in various tumor processes including tumor progression. Hence the current study aimed to investigate the role of bone marrow mesenchymal stem cell (BMSC)-derived exosomal microRNA-126-3p (miR-126-3p) in pancreatic cancer. Initially, miRNA candidates and related genes associated with pancreatic cancer were screened. PANC-1 cells were transfected with miR-126-3p or silenced a disintegrin and a metalloproteinase-9 (ADAM9) to examine their regulatory roles in pancreatic cancer cells. Additionally, exosomes derived from BMSCs were isolated and co-cultured with pancreatic cancer cells to elucidate the effects of exosomes in pancreatic cancer. Furthermore, the effects of overexpressed miR-126-3p derived from BMSCs exosomes on proliferation, migration, invasion, apoptosis, tumor growth, and metastasis of pancreatic cancer cells were analyzed in connection with lentiviral packaged miR-126-3p in vivo. Restored miR-126-3p was observed to suppress pancreatic cancer through downregulating ADAM9. Notably, overexpressed miR-126-3p derived from BMSCs exosomes inhibited the proliferation, invasion, and metastasis of pancreatic cancer cells, and promoted their apoptosis both in vitro and in vivo. Taken together, the key findings of the study indicated that overexpressed miR-126-3p derived from BMSCs exosomes inhibited the development of pancreatic cancer through the downregulation of ADAM9, highlighting the potential of miR-126-3p as a novel biomarker for pancreatic cancer treatment.

Abstract
Our preliminary data showed that VEGFR2 upregulation promoted renal ROS overproduction in high-fat diet- (HFD-) treated mice. Given that ROS-induced NLRP3 activation plays a central role in the pathogenesis of type 2 diabetic kidney injury, we evaluate whether VEGFR2 upregulation induces type 2 diabetic kidney injury via ROS-mediated NLRP3 activation and further explore the underlying mechanism. Our results showed that VEGFR2 knockdown decreased ROS overproduction, blocked NLRP3-dependent inflammation, and alleviated kidney damage in HFD-treated mice. Treatment with α-lipoic acid, a scavenger of ROS, lowered ROS overproduction and alleviated NLRP3-triggered kidney injury of HFD-treated mice. Collectively, the VEGFR2/ROS/NLRP3 signal is a critical therapeutic strategy for the kidney injury of HFD-treated mice. Purple sweet potato color (PSPC), a natural anthocyanin, can exert renal protection by inhibiting ROS in HFD-treated mice. Here, we provide a novel mechanism of PSPC against renal damage in HFD-treated mice by downregulating VEGFR2 expression.

Abstract
Myasthenia gravis (MG) is an autoimmune neuromuscular disorder, affecting the quality of life of millions of people worldwide. The present study aims to determine the relationship between micro-RNA-143 (miR-143) and C-X-C motif chemokine 13 (CXCL13) and whether it influences the pathogenesis of myasthenia gravis (MG). Thymus specimens were resected from patients with thymic hyperplasia combined with MG and then infused into normal mouse cavities to establish MG mouse models. Immunohistochemistry, reverse transcription-quantitative PCR, in situ hybridization detection, and Western blot analysis were employed to identify the expression of miR-143 and CXCL13 in MG and normal mice. The obtained thymocytes were cultured in vitro and transfected with a series of miR-143 mimic, miR-143 inhibitor, overexpression of CXCL13, or siRNA against CXCL13. MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] and flow cytometry assays were employed to assess cell viability, cycle entry, and apoptosis of the thymocytes. Dual-luciferase reporter assay provided verification, confirming that CXCL13 was the target gene of miR-143. Low miR-143 expression in the thymus tissues of the MG mice was detected, which presented with a reciprocal relationship with the expression rate of CLCX13. Observations in relation to the interactions between miR-143 mimic or siRNA-CXCL13 exposure showed reduced cell viability, with a greater number of cells arrested at the G0/G1 phase and a greater rate of induced apoptosis. Furthermore, overexpression of CXCL13 rescued miR-143 mimic-induced apoptosis. The findings have identified the potential role of miR-143 as a MG development mediator by targeting CXCL13. The key results obtained provide a promising experimental basis for targeted intervention treatment with miR-143.

Abstract
BACKGROUND/AIMS Parkinson's disease (PD) is a neurodegenerative movement disease with a high annual incidence. Accumulating evidence demonstrates that microRNAs play important roles in the pathogenesis of multiple neurological disorders, including PD. This study aims to investigate how microRNA-200a (miR-200a) regulates striatal dopamine receptor D2 (DRD2) to affect apoptosis of striatum in rats with PD and to explore the associated mechanism. METHODS After successfully establishing a PD model by 6-hydroxydopamine injections, PD rats were mainly treated with miR-200a mimics, inhibitors, Forskolin or a combination of miR-200a inhibitors and Forskolin. High-performance liquid chromatography-electrochemical detection (HPLC-ECD) was employed to detect the levels of dopamine, 3, 4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA), and chemistry colorimetric methods were applied to detect the levels of malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). A TUNEL assay and immunocytochemical staining were performed to observe apoptosis and tyrosine hydroxylase (TH)-positive cells in the striatum. The expression of miR-200a, DRD2, Bad, Bax, Bcl-2, cAMP and PKA was determined by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blot assays. RESULTS In the cellular experiments, after transfection with the inhibitor of miR-200a, decreased levels of Bax, GSH-Px, SOD, dopamine, DOPAC and HVA but increased levels of MDA and Bcl-2 were found along with a reduced apoptosis rate and increased TH-positive cell number. In addition, downregulating miR-200a resulted in lower expression of AKT, cAMP and PKA but higher expression of DRD2 and CREB, indicating that the downregulation of miR-200a increases DRD2 expression, which blocks the cAMP/PKA signaling pathway. CONCLUSION This study provides evidence that the inhibition of miR-200a can repress apoptosis in the striatum via inhibition of the cAMP/PKA signaling pathway by upregulating DRD2 expression in PD rats.

Abstract
Glioma is known to be the most prevalent primary brain tumor. In recent years, there has been evidence indicating myeloid cell leukemia-1 (MCL1) plays a role in brain glioblastoma. Therefore, the present study was conducted with aims of exploring the ability of MCL1 silencing to influence glioma cell senescence and apoptosis through the mediation of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway. Glioma and tumor-adjacent tissues were collected in order to detect the presence of higher levels of MCL1 protein expression. Next, the mRNA and protein expression of MCL1, PI3K, Akt, B cell lymphoma 2 (Bcl2), Bcl2-associated X (Bax), B lymphoma Mo-MLV insertion region 1 homolog (Bmi-1), and phosphatase and tensin homolog (PTEN) were determined. Cell counting kit-8 assay was applied to detect cell proliferation, β-galactosidase staining for cell senescence, and flow cytometry for cell cycle entry and apoptosis. Initially, the results revealed higher positive expression rate of MCL1 protein, increased mRNA and protein expression of MCL1, PI3K, Akt, Bmi-1, and Bcl-2 and decreased that of Bax and PTEN in human glioma tissues. The silencing of MCL1 resulted in a decrease in mRNA and protein expression of PI3K, Akt, Bmi-1, and Bcl-2 and an increase in Bax and PTEN expressions in glioma cells. Moreover, silencing of MCL1 also inhibited cell proliferation and cell cycle entry in glioma cells, and promoted glioma cell senescence and apoptosis. In conclusion, the aforementioned results collectively suggested that the silencing of MCL1 promotes senescence and apoptosis in glioma cells through inhibiting the PI3K/Akt signaling pathway. Thus, decreasing the expression of MCL1 might have therapeutic functions in glioma. © 2018 IUBMB Life, 71(1):81-92, 2019.

Abstract
Purpose: Gastric cancer is mainly treated by gastrectomy, the results of which were unsatisfactory without any adjuvant treatments. This study aimed to examine the performance of radiotherapy, chemotherapy, and chemoradiotherapy after surgery in order to acquire the optimal adjuvant treatment. Method: Embase and PubMed were retrieved to conduct a systematic research. Hazard ratios (HR) of overall survival (OS) and progression-free survival (PFS) as outcomes were calculated by synthesizing direct and indirect evidence to evaluate the efficacy of three treatments against surgery alone. The P-score ranking was utilized to rank the therapies. Consistency was assessed by heat plot. Begg's test was performed to evaluate publication bias. Results: A total of 35 randomized controlled studies (RCTs) with 8973 patients were included in our network meta-analysis (NMA). As for efficacy outcomes, OS and PFS of 1, 2, 3, and 5 years, all revealed chemoradiotherapy (CRT) as the best of three adjuvant therapies. Meanwhile, P-score ranking results also displayed that CRT was the optimal regimen. Additionally, radiotherapy (RT) and chemotherapy (CT) were two alternative options following CRT since RT performed well in short-term survival while CT could improve the long-term survival. Conclusion: CRT was the most recommended therapy to accompany surgery according to our results. However, no analysis about the safety of these three treatments was mentioned in our study. Further studies including safety outcomes were required to draw a more comprehensive conclusion.

Abstract
BACKGROUND/AIMS Spinal cord glioma is a highly aggressive malignancy that commonly results in high mortality due to metastasis, high recurrence and limited treatment regimens. This study aims to elucidate the effects of long non-coding RNA LINC01260 (LINC01260) on the proliferation, migration and invasion of spinal cord glioma cells by targeting Caspase recruitment domain family, member 11 (CARD11) via nuclear factor kappa B (NF-κB) signaling. METHODS The Multi Experiment Matrix (MEM) website was used for target gene prediction, and the DAVID database was used for analysis of the relationship between CARD11 and the NF-κB pathway. In total, 60 cases of glioma tissues and adjacent normal tissues were collected. Human U251 glioma cells were grouped into blank, negative control (NC), LINC01260 vector, CARD11 vector, siRNA-LINC01260, siRNA-CARD11, LINC01260 vector + CARD11 vector and LINC01260 + siRNA-CARD11 groups. A dual-luciferase reporter assay was conducted to verify the target relationship between LINC01260 and CARD11. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blot analysis were employed to assess expression of LINC01260, E-cadherin, p53, CARD11, Ki67, N-cadherin, matrix metalloproteinase (MMP)-9, NF-κBp65 and NF-κBp50. MTT, flow cytometry, wound-healing and Transwell assays were performed to examine cell viability, the cell cycle, apoptosis, invasion and migration. Tumor growth was assessed through xenografts in nude mice. RESULTS CARD11 was confirmed to be a target gene of LINC01260 and was found to be involved in regulating the NF-κB pathway. Compared with adjacent normal tissues, glioma tissues showed reduced expression of LINC01260 and elevated expression of CARD11 and genes related to apoptosis, invasion and migration; activation of NF-κB signaling was also observed. In contrast to the blank and NC groups, an elevated number of cells arrested in G1 phase, increased apoptosis and reduced cell proliferation, invasion and number of cells arrested in S and G2 phases, as well as tumor growth were found for the LINC01260 vector and siRNA-CARD11 groups. CONCLUSIONS Our findings demonstrate that overexpression of LINC01260 inhibits spinal cord glioma cell proliferation, migration and invasion by targeting CARD11 via NF-κB signaling suppression.

Abstract
Objective: To analyze the correlation between circumcision and incidence and clearance of male genital HPV infection. Methods: From May to July 2014, 18-55 year old men who had sexual behavior history were recruited from the general population in Liuzhou, Guangxi to set up a cohort. Totally, 113 circumcised and 560 uncircumcised men were enrolled and interviewed using a questionnaire (including information on demographic characteristics and sexual behaviors), then they were followed-up with 6-month interval for 2 times. On each visit, specimens of male external genitalia were collected and genotyped for HPV DNA. The differences of incidence and clearance of genital HPV infections between circumcised and uncircumcised men were analyzed by Log-rank test. Cox regression was used to analyze the relationship between circumcision and incidence and clearance of HPV infection. Results: The median age (P(25), P(75)) of circumcised and uncircumcised men were 28 (24, 35) and 32 (24, 31), respectively. The incidences of any HPV infections were 9.1 (95%CI: 2.4-15.7) and 8.4 (95% CI: 5.6-11.2) per 1 000 person-months (χ(2)=0.10, P=0.758), respectively. The clearance of circumcised men [136.3 (95%CI: 70.0-202.7) per 1 000 person-months] was higher than that in uncircumcised men [89.6 (95%CI: 65.9-113.3) per 1 000 person-months] (χ(2)=8.19, P=0.004). In multivariate COX regression analysis, compared with uncircumcised men, circumcised men had higher possibility to clear any HPV infections (HR: 2.41, 95%CI: 1.30-4.46). Compared with men having one sexual partner, people having more than 4 sexual partners had lower possibility to clear any HPV infections (HR: 0.49, 95%CI: 0.25-0.96). Compared with 18-25 years old men, men aged 26-35 years old had higher possibility to clear high-risk HPV infections (HR: 2.14, 95%CI: 1.08-4.23). Conclusion: Circumcised and uncircumcised men had similar incidence of genital HPV infection, whereas, men conducted circumcision and having fewer sexual partners could increase the clearance of genital HPV infections.

Abstract
Background/Aims: MiRNAs are involved in phenotype modulation of neural cells after peripheral nerve injury. However, the roles of miRNAs on the survival of dorsal root ganglion (DRG) neurons have not yet been fully understood. Methods: In this study, the expression of miR-142-3p was measured in rat DRGs (L4-L6) during the initial 24 hours post sciatic nerve transection by microarray profiling and quantitative PCR. The functional assays including the cell viability, colony formation, cell cycle and apoptosis assays were performed in miR-142-3p mimic or inhibitor transfected cell lines. Results: MiR-142-3p was identified to be siginificantly upregulated in rat DRGs (L4-L6) during the initial 24 hours post sciatic nerve transection. MiR-142-3p mimic enhanced cell viability by promoting cell cycle and inhibiting cell apoptosis in cultured DRG neurons. In addition, cyclin-dependent kinase inhibitor 1B (CDKN1B, also known as p27/Kip1) and tissue inhibitor of metalloproteinase 3 (TIMP3) were identified as targets of miR-142-3p. Furthermore, knockdown of CDKN1B or TIMP3 by specific siRNAs could reverse the effect of miR-142-3p. Conclusions: In the conclusion, the results showed that miR-142-3p could promote neuronal cell cycle and inhibit apoptosis at least partially through suppressing CDKN1B and TIMP3 after peripheral nerve injury.

Abstract
Background/Aims: Parkinson’s disease (PD) is the second most common neurodegenerative disease after Alzheimer’s disease, and recent studies suggested that oxidative stress (OS) contributes to the cascade that leads to dopamine cell degeneration in PD. In this study, we hypothesized that salidroside (SDS) offers protection against OS injury in 6-hydroxydopamine (6-OHDA) unilaterally lesioned rats as well as the underlying mechanism. Methods: SDS and LiCl (activators of the Wnt/β-catenin signaling pathway) administration alone and in combination with 6-OHDA injection in rats was performed 3 days before modeling for 17 consecutive days to verify the regulatory mechanism by which SDS affects the Wnt/β-catenin signaling pathway as well as to evaluate the protective effect of SDS on PD in relation to OS in vivo. In addition, pheochromocytoma 12 (PC12) cells were incubated with 10 µmol/L SDS or LiCl alone or with both in combination for 1 h followed by a 24-h incubation with 100 µmol/L 6-OHDA to obtain in vitro data. Results: In vivo the administration of LiCl was found to ameliorate behavioral deficits and dopaminergic neuron loss; increase superoxide dismutase (SOA) activity, glutathione peroxidase (GSH-Px) levels, and glycogen synthase kinase 3β phosphorylation (GSK-3β-Ser9); reduce malondialdehyde (MDA) accumulation in the striatum and the GSK-3β mRNA level; as well as elevate β-catenin and cyclinD1 mRNA and protein levels in 6-OHDA-injected rats. This SDS treatment regimen was found to strengthen the beneficial effect of LiCl on 6-OHDA-injected rats. In vitro LiCl treatment decreased the toxicity of 6-OHDA on PC12 cells and prevented apoptosis. Additionally, LiCl treatment increased SOA activity, GSH-Px levels, and GSK-3β-Ser9 phosphorylation; decreased MDA accumulation in the striatum and GSK-3β mRNA levels; as well as increased β-catenin and cyclinD1 mRNA and protein levels in 6-OHDA-treated PC12 cells. Additionally, SDS treatment increased the protective effect of LiCl on 6-OHDA-treated PC12 cells. Conclusion: Evidence from experimental models suggested that SDS may confer neuroprotection against the neurotoxicity of 6-OHDA in response to OS injury and showed that these beneficial effects may be related to regulation of the Wnt/β-catenin signaling pathway. Therefore, SDS might be a potential therapeutic agent for treating PD.

Abstract
Evidence indicates that oxidative stress is the central pathological feature of 2, 2´, 4, 4´-tetrabromodiphenyl ether (BDE-47)-induced neurotoxicity. Protein kinase C delta (PKCδ), an oxidative stress-sensitive kinase, can be proteolytically cleaved to yield a catalytically active fragment (PKCδ-CF) that is involved in various neurodegenerative disorders. Here, we showed that BDE-47 treatment increased ROS, malondialdehyde, and protein carbonyl levels in the mouse hippocampus. In turn, excessive ROS induced caspase-3-dependent PKCδ activation and stimulated NF-κB p65 nuclear translocation, resulting in inflammation in the mouse hippocampus. These changes caused learning and memory deficits in BDE-47-treated mice. Treatment with Z-DEVD-fmk, a caspase-3 inhibitor, or N-acetyl-L-cysteine, an antioxidant, blocked PKCδ activation and subsequently inhibited inflammation, thereby improving learning and memory deficits in BDE-47-treated mice. Our data further showed that activation of ROS-PKCδ signaling was associated with DJ-1 downregulation, which exerted neuroprotective effects against oxidative stress induced by different neurotoxic agents. Adeno-associated viral vector-mediated DJ-1 overexpression in the hippocampus effectively inhibited excessive ROS production, suppressed caspase-3-dependent PKCδ cleavage, blunted inflammation and ultimately reversed learning and memory deficits in BDE-47-treated mice. Taken together, our results demonstrate that DJ-1 plays a pivotal role in BDE-47-induced neurotoxic effects and learning and memory deficits.

Abstract
Diabetes often causes learning and memory deficits, which leads to unfavorable behavioral performance. In this study, we investigated the effects of long non-coding RNA (lncRNA) ANRIL on learning, memory abilities, and hippocampal neuronal apoptosis via the NF-κB signaling pathway in streptozotocin (STZ)-induced diabetic rats. After successful establishment of diabetic rat models, the subjects were then assigned into the DM, DM + si-ANRIL, DM + si-negative control (si-NC) groups, as well as an additional normal group. Morris water maze test was employed to assess behavioral performance of rats, followed by the recording of body weight and blood glucose levels. Expressions of ANRIL, NF-κB signaling pathway-related, and apoptosis-related genes were examined by qRT-PCR and western blotting. Rat hippocampus expression levels of cleaved-caspase-3 were determined by immunofluorescence. Cell apoptosis was examined by TUNEL assay. Versus to the normal group, revealed there to be activation of the NF-κB signaling pathway, decreased weight, increased blood glucose, increased escape latency, reduced residence time, memory impairment, increased cleaved-caspase-3 expression, and increased apoptosis were detected in the DM and DM + si-NC groups. The DM + si-ANRIL group exhibited inhibited NF-κB signaling pathway, weight loss, decreased blood glucose, recovered memory, decreased cleaved-caspase-3 expression and reduced apoptosis compared to the DM group, with higher weight of rats, lower blood glucose levels, and stronger memory abilities in the DM + si-ANRIL group. Taken together, these findings indicate that silencing lncRNA ANRIL promotes memory recovery and decreases hippocampal neurons apoptosis in diabetic rats through the inhibition of the NF-κB signaling pathway.

Abstract
The present study was to investigate the effect of lncRNA LINC00880 targeting CACNG5 on cell proliferation, migration, invasion, and apoptosis in spinal cord ependymoma (SCE) through the MAPK signaling pathway. GEO database was used to download gene expression data related with SCE (GSE50161 and GSE66354) and annotation file. LncRNA with differential expression was predicted by Multi Experiment Matrix website (MEM). The target gene was analyzed by KEGG pathway enrichment analysis. SCE tissues and adjacent tissues were collected. The positive expression of CACNG5 protein was tested by immunohistochemistry. Expression of LINC00880, CACNG5, and MAPK signaling pathway-related proteins was measured with qRT-PCR and Western blotting. Cell proliferation, migration, invasion, cycle, and apoptosis were detected using MTT, Transwell assay, Scratch test, and Flow cytometry. SCE tissues showed increased LINC00880 expression. CACNG5 was a target gene of LINC00880 and correlated with MAPK signaling pathway. Compared with adjacent tissues, SCE tissues showed lower positive expression of CACNG5. Compared with the blank group, LINC00880 expression was higher in the LINC00880 vector and LINC00880 vector + CACNG5 vector groups, and lower in the si-LINC00880 and si-LINC00880 + si-CACNG5 groups; in the LINC00880 vector and si-CACNG5 groups, expression of survivin, p38MAPK, ERK1/2, JNK1/2/3 increased and CACNG5 and Bax expression reduced, the proliferation, invasion and migration of tumor cells increased, and apoptosis rate decreased. Opposite results were found in the si-LINC00880 and CACNG5 vector groups. The findings indicate that lncRNA LINC00880 targeting CACNG5 inhibits cell apoptosis and promotes proliferation, migration, and invasion in SCE through the MAPK signaling pathway.

Abstract
Epilepsy is a group of neurological disorders characterized by epileptic seizures. In this study, we aim to explore the role of microRNA-421 (miR-421) in hippocampal neurons of epilepsy mice via the TLR/MYD88 pathway. Forty mice were randomly served as the normal and model (established as epilepsy model) groups. Hippocampal neurons were assigned into seven groups with different transfections. The RT-qPCR and western blotting were conducted to examine the expression of miR-421 TLR2, TLR4, MYD88, Bax, Bcl-2, p53, Beclin-1, and LC3II/LC3I. Cell proliferation and apoptosis were detected by MTT and flow cytometry.MYD88 is a target gene of miR-421. Model mice showed elevated expression of TLR2, TLR4, MYD88, Bax, p53, Beclin-1, and LC3II/LC3I but reduced expression of miR-421 and Bcl-2. In vitro experiments reveals that overexpression of miR-421 inhibited the TLR/MYD88 pathway. Besides, overexpressed miR-421 declined cell apoptosis but increased cell proliferation. It reveals that miR-421 targeting MYD88 could inhibit the apoptosis and autophagy of hippocampal neurons in epilepsy mice by down-regulating the TLR/MYD88 pathway.

Abstract
Hypoxia–ischaemia (HI) remains a major cause of foetal brain damage presented a scarcity of effective therapeutic approaches. Dexmedetomidine (DEX) and microRNA‐140‐5p (miR‐140‐5p) have been highlighted due to its potentially significant role in the treatment of cerebral ischaemia. This study was to investigate the role by which miR‐140‐5p provides cerebral protection using DEX to treat hypoxic–ischaemic brain damage (HIBD) in neonatal rats via the Wnt/β‐catenin signalling pathway. The HIBD rat models were established and allocated into various groups with different treatment plans, and eight SD rats into sham group. The learning and memory ability of the rats was assessed. Apoptosis and pathological changes in the hippocampus CA1 region and expressions of the related genes of the Wnt/β‐catenin signalling pathway as well as the genes responsible of apoptosis were detected. Compared with the sham group, the parameters of weight, length growth, weight ratio between hemispheres, the rate of reaching standard, as well as Bcl‐2 expressions, were all increased. Furthermore, observations of increased levels of cerebral infarction volume, total mortality rate, response times, total response duration, expressions of Wnt1, β‐catenin, TCF‐4, E‐cadherin, apoptosis rate of neurons, and Bax expression were elevated. Following DEX treatment, the symptoms exhibited by HIBD rats were ameliorated. miR‐140‐5p and si‐Wnt1 were noted to attenuate the progression of HIBD. Our study demonstrates that miR‐140‐5p promotes the cerebral protective effects of DEX against HIBD in neonatal rats by targeting the Wnt1 gene through via the negative regulation of the Wnt/β‐catenin signalling pathway.

Abstract
Previous studies suggested that lower vitamin D might be a risk factor for autism spectrum disorders (ASDs). The aim of this study was to estimate the prevalence of ASDs in 3-year-old Chinese children and to examine the association between neonatal vitamin D status and risk of ASDs. We conducted a study of live births who had taken part in expanded newborn screening (NBS), with outpatient follow-up when the children 3-year old. The children were confirmed for ASDs in outpatient by the Autism Diagnostic Interview-Revised and Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 criteria. Intellectual disability (ID) status was defined by the intelligence quotient (IQ < 80) for all the participants. The study design included a 1:4 case to control design. The concentration of 25-hydroxyvitamin D3 [25(OH)D3] in children with ASD and controls were assessed from neonatal dried blood samples. A total of 310 children were diagnosed as having ASDs; thus, the prevalence was 1.11% (95% CI, 0.99% to 1.23%). The concentration of 25(OH)D3 in 310 ASD and 1240 controls were assessed. The median 25(OH)D3 level was significantly lower in children with ASD as compared to controls (p < 0.0001). Compared with the fourth quartiles, the relative risk (RR) of ASDs was significantly increased for neonates in each of the three lower quartiles of the distribution of 25(OH)D3, and increased risk of ASDs by 260% (RR for lowest quartile: 3.6; 95% CI, 1.8 to 7.2; p < 0.001), 150% (RR for second quartile: 2.5; 95% CI, 1.4 to 3.5; p = 0.024), and 90% (RR for third quartile: 1.9; 95% CI, 1.1 to 3.3; p = 0.08), respectively. Furthermore, the nonlinear nature of the ID-risk relationship was more prominent when the data were assessed in deciles. This model predicted the lowest relative risk of ID in the 72rd percentile (corresponding to 48.1 nmol/L of 25(OH)D3). Neonatal vitamin D status was significantly associated with the risk of ASDs and intellectual disability. The nature of those relationships was nonlinear. © 2017 American Society for Bone and Mineral Research.

Abstract
This network meta-analysis compared the short-term and long-term efficacies of first-line chemotherapy regimens in patients with advanced colorectal cancer (CRC). The 10 regimens included folinic acid + 5-fluorouracil + oxaliplatin (FOLFOX), folinic acid + 5-fluorouracil + irinotecan (FOLFIRI), folinic acid + 5-fluorouracil + gemcitabine (FFG), folinic acid + 5-fluorouracil + trimetrexate (FFT), folinic acid + 5-fluorouracil (FF), irinotecan + oxaliplatin (IROX), raltitrexed + oxaliplatin (TOMOX), folinic acid + tegafur-uracil (FTU), raltitrexed, and capecitabine. Electronic searches were performed in the Cochrane Library, PubMed and Embase databases from inception to June 2017. Network meta-analysis combined direct and indirect evidence to obtain odds ratios (ORs) and surface under the cumulative ranking curves (SUCRA) of different chemotherapy regimens for advanced CRC. Fourteen randomized controlled trails (RCTs) covering 4,383 patients with advanced CRC were included. The results revealed that FOLFOX, FOLFIRI, IROX, and TOMOX all showed higher overall response rates (ORRs) than FF or raltitrexed. Compared with raltitrexed, the aforementioned four regimens also had higher 1-year progression-free survival (PFS) rates. In addition, FOLFOX and FOLFIRI exhibited higher disease control rates (DCRs) and 1-year PFS rates than FF or raltitrexed. Cluster analysis revealed that FOLFOX, FOLFIRI, and TOMOX had better short-term and long-term efficacies. These findings suggest FOLFOX, FOLFIRI, and TOMOX are superior to other regimens for advanced CRC. These three regimens are therefore recommended for clinical treatment of advanced CRC.

Abstract
We investigated the involvement of microRNA-433 (miR-433) in the proliferation, migration, and invasiveness of oral squamous cell carcinoma (OSCC). Totally 108 OSCC tissues and adjacent normal tissues from patients with OSCC were collected. Also, transplanted tumor formation experiment in nude mice was conducted to verify the effect of miR-433 and FAK on subcutaneous transplanted tumor. The CD44+ stem cell from SCC-9 were collected and assigned into the blank, miR-433 mimics, mimics control, miR-433 inhibitors, inhibitors control, siFAK and miR-433 inhibitors + siFAK groups. The qRT-PCR and western blotting were used to detect miR-433, FAK, ERK, MEK, pERK and pMEK after transfection. Flow cytometry, MTT assay, scratch test and Transwell assay were performed to determine the cell proportion, growth, migration and invasion of SCC-9 cells. In cell line SCC-9, expression of CD133, Oct-4, and BIM-1 was greater in CD44+ cells than CD44- cells, indicating that CD44+ cells had characteristics of tumor stem cells. Expression of FAK, ERK, MEK, p-ERK and p-MEK was decreased in tumor tissues from the CD44-, miR-433, and siFAK groups. Expression of MiR-433 mRNA was elevated, while levels of FAK, ERK, MEK, p-ERK, and p-MEK mRNA were all decreased in the miR-433 mimics group. In the miR-433 mimics and siFAK groups, cell proliferation, migration, and invasion were all decreased, while the opposite trends were seen in the miR-433 inhibitor group. These results indicate that miR-433 downregulates FAK through the ERK/MAPK signaling pathway to inhibit the proliferation, migration, and invasiveness of SCC-9 OSCC cells.

Abstract
It is now commonly known that exposure to polybrominated diphenyl ethers (PBDEs) may cause neurotoxicity and cognitive deficits in children as well as adults, but the underlying mechanisms are still not clear. In the present study, we aimed to elucidate the potential underlying mechanism of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47)-induced neurotoxicity and cognitive impairment. Our results showed that BDE-47-treated mice exhibited impaired cognition and robust upregulation of nuclear TDP-43 in the hippocampus. Hippocampus-specific TDP-43 knockdown attenuated hippocampal apoptosis, restored synaptic protein levels and thus improved cognitive dysfunction in BDE-47-treated mice. Furthermore, our data demonstrated that NLRP3 inflammasome activation played a distinct role in the upregulation of nuclear TDP-43 by downregulating Parkin in the hippocampus of BDE-47-treated mice. Knocking down NLRP3 in the hippocampus or inhibiting caspase 1 activity in BDE-47-treated mice effectively increased Parkin expression in the hippocampus, which decreased the levels of nuclear TDP-43 and ultimately abrogated TDP-43-induced neurotoxic effects. Taken together, our data indicate that TDP-43 upregulation mediated by NLRP3 inflammasome activation via Parkin downregulation in the hippocampus induces cognitive decline in BDE-47-treated mice, and suggest that inhibition of NLRP3 or TDP-43 may be a potential strategy for the prevention or treatment of cognitive impairment in BDE-47-induced neurotoxicity and brain diseases.

Abstract
The aim of this study was to investigate the correlation of expression of IGF1R-RACK1-STAT3 and Bcl-xl in nasopharyngeal carcinoma (NPC) with the clinicopathological features and the prognosis of NPC. Our study selected 215 NPC tissues and 178 chronic nasopharyngitis tissues (control group). Positive expression rates of IGF1R, RACK1, STAT3, and Bcl-xl were tested by immunohistochemical method, and expression of IGF1R, RACK1, STAT3, Bcl-xl, Bcl-2, and Bax by western blotting. Correlation of IGF1R, RACK1, STAT3, and Bcl-xl with the clinicopathological features of NPC was analyzed. The correlation among those four expression was analyzed by Spearman. The survival of NPC and independent factors of prognosis were tested by Kaplan-Meier and COX proportional hazards model respectively. The NPC group had higher positive expression rates of IGF1R, RACK1, STAT3, and Bcl-xl, and elevated expression of IGF1R, RACK1, STAT3, Bcl-xl, Bcl-2, and Bax. The lymph node metastasis (LNM) group had higher positive expression rates of IGF1R and RACK1 when compared with the non-LNM group. Patients with stage III and IV had higher positive expression rates of IGF1R, RACK1, STAT3, and Bcl-xl. There was positive correlation between expression of IGF1R and RACK1, STAT3. Such correlation was found between RACK1 and STAT3. Patients with negative expression of IGF1R, RACK1, STAT3, and Bcl-xl had higher survival rates. The risky factors of poor prognosis of NPC were positive expression of IGF1R, RACK1, STAT3 and Bcl-xl, and LNM. IGF1R-RACK1-STAT3 and Bcl-xl expression correlated with the clinicopathological features and poor prognosis of NPC.

Abstract
Objective: To analyze the type-specific prevalence of human papillomavirus (HPV) among women aged 18-45 years from the general population in Liuzhou, Guangxi Zhuang Autonomous Region. Methods: Totally, 2 300 women aged 18-45 years old were enrolled in Liuzhou,from March to July, 2013. Cervical exfoliated cells were collected for liquid based cytological and HPV DNA tests. Women were referred to colposcopy exam, based on the clinical practice guideline. Results: Overall, the prevalence rates of any HPV or oncogenic HPV appeared as 22.7% (95% CI: 21.0%-24.4%) and 17.3% (95% CI: 16.0%-19.1%), respectively in this population under study. The high-risk HPV prevalence peaked at the age groups of 18-25 and 41-45, increasing along with the severity through cytological and histological tests. Statistically significant differences between the prevalence of CIN2+ (Cervical intraepithelial neoplasia 2+) in women older than 26 years (1.7%, 95% CI: 1.0%-2.4%) and 18-25 years (1.2%, 95% CI: 0.5%-1.9%) of age, were not observed. Among samples diagnosed as CIN2+, positivity of HPV bivalent (16/18) and nine-valent (6/11/16/18/31/33/45/52/58) vaccine, related high risks on the types of HPV types appeared as 44.1% and 97.1%. Conclusions: The age-specific HPV prevalence rates in the general women aged 18-45 in Liuzhou presented as having bimodal distribution, suggesting that the disease burden of cervical diseases in women aged 26-45 years should not be ignored. Nine-valent HPV vaccine might provide more effective prevention outcomes on cervical cancer in China.

Abstract
Graves' disease is an autoimmune process in which the thyroid gland is triggered by autoantibodies, resulting in hyperthyroidism. The purpose of the present study is to elucidate whether exon-1 49 A/G and promoter region 318C/T polymorphisms in the CTLA-4 gene. This study consisted of 653 eligible patients with Graves' disease. After receiving 131I radionuclide therapy, these patients were classified into the remission and non-remission groups. A logistic regression-based model was used to analyze independent factors affecting the patient response to 131I radionuclide therapy. The results showed that CTLA-4 49 A/G was closely related to the efficacy of 131 I treatment for Graves' disease (AG + GG vs. AA: OR = 6.543, 95%CI = 2.611 ∼ 16.40, P < 0.001; G vs. A: OR = 3.482, 95%CI = 2.457 ∼ 4.934, P < 0.001). Moreover, the findings revealed that haplotype A-C (P < 0.001, OR = 3.592, 95%CI: 2.451 ∼ 5.262) and G-C (P < 0.001, OR = 0.282, 95%CI: 0.204 ∼ 0.391) were associated with the efficacy of 131 I therapy in treating Graves' disease. Logistic regression analysis indicated that thyroid weight (OR = 0.963, 95%CI = 0.944 ∼ 0.982, P < 0.001) and CTLA-4 exon-1 49 A/G polymorphism (OR = 0.334, 95%CI = 0.233 ∼ 0.478, P < 0.001) independently affect the efficacy of 131 I therapy in Graves' disease. These data indicated that CTLA-4 exon-1 49 A/G polymorphism may be associated with patient response to radionuclide 131 I therapy in Graves' disease.

Abstract
Objective: To understand the level of bactericidal antibodies against Neisseria meningitidis and their rate of protection in children aged between 3 and 23 months, in Liuzhou, in 2012. Methods: Convenience sampling was performed in Liujiang, Rong'an and Sanjiang Counties from May through August, 2012. The inclusion criteria for 603 subjects were: Children aged between 3 and 23 months; no history of meningococcal meningitis; no vaccination against Neisseria meningitidis serogroup C; more than 30 days from the last vaccination against Neisseria meningitidis serogroup A. Demographic information and immunization history of the subjects were obtained using questionnaires. Venous blood samples (2.0 ml each) were collected and levels of Neisseria meningitides antibodies determined using a Serum Bactericidal Assay (SBA). The geometric mean titer (GMT) of serum bacterial antibodies was positive when it was greater than or equal to 1∶2 and protective when greater than 1∶8. Chi-square and Fisher's exact tests were used to compare differences in the positive and protective rates of serum antibodies of Neisseria meningitidis serogroup A and Neisseria meningitidis serogroup C, among children with different demographic characteristics. Kruskal-Wallis H test was used to compare differences in the GMT of serum antibodies of Neisseria meningitidis serogroup A and Neisseria meningitidis serogroup C, among children with different demographic characteristics. Results: Of 603 subjects, 325 (53.9%) were female and 278 (46.1%) were male; 276 (45.8%), 143 (23.7%) and 184 (30.5%) subjects were administered, respectively, no treatment, 1 dose vaccine and 2 doses vaccine. The GMT of serum antibodies against group A Neisseria meningitidis was 1∶1.11, the positive rate was 7.6% (46) and the protective rate was 2.0% (12). The GMT of antibodies in children receiving 1 vaccine dose was 1∶1.16 and the protective rate was 3.5% (5), both values higher than those in children receiving 2 vaccine doses (GMT: 1∶1.2, protective rate: 3.5% (5)). However, these differences were not statistically significant (GMT: H=0.64, P=0.728; protective rate: Fisher's exact test, P= 0.080). The GMT of antibodies in children receiving 1 and 2 doses of meningococcal polysaccharide vaccines were 1∶1.12 and 1∶2.30, respectively (≤180 d). The GMT of serum antibodies for group C meningococcal vaccine was 1∶1.18 and its positive and protective rates were 14.6% (88) and 2.2% (13), respectively. Conclusion: Children aged between 3 and 23 months are susceptible to Neisseria meningitidis groups A and C. The immune effectiveness of group A meningococcal polysaccharide vaccine is relatively poor in this age group and their antibody levels decreased rapidly.

Abstract
Objective: This study aimed to investigate the clinical, biochemical and genetic features of two Chinese children with hereditary folate malabsorption. Method: Clinical features, laboratory examinations, treatment and SLC46A1 gene of two cases were studied. Reports on hereditary folate malabsorption utill September of 2016 were searched and the clinical and genetic characteristics of reported cases were summarized. Result: The two patients presented with megaloblastic anemia from their infant period and seizures, psychomotor retardation and regression. In case1, mean corpuscular volume (MCV) was 100 fl. Serum folate was 9.96 nmol/L. Folate and 5-methylenetetrahydrofolate in cerebrospinal fluid were 0 and 0.01 separately. In case 2, MCV was 93.9 fl. Serum folate was 4.49 nmol/L. The concentration of folate and 5-methylenetetrahydrofolate in cerebrospinal fluid were both zero. On their brain CT, progressive bilateral symmetrical calcification was observed. On their SLC46A1 gene, four mutations were identified. Case 1 had one novel mutation, c. 1238T>C (L413P) and c. 194-195insG (p.Cys66LeufsX99). From Case 2, two reported mutations, c. 1A>T (M1L) and c. 194-195insG (p.Cys66LeufsX99) were identified. The administration of folinic acid (60 to 120 mg per day) was initiated after diagnosis. Clinical improvement and normalized hematologic markers were observed after treatment. Totally 37 cases were reported in reviewed English literature, including 30 cases with mutations on SLC46A1 gene (only one Chinese patient). All the cases had the onset in infancy. The ratio of boys to girls was 1 to 1.5. Main manifestations were characterized by megaloblastic anemia (77%), failure to thrive (50%), diarrhea (27%), psychomotor retardation (63.6%), epilepsy (27%), and infection of respiratory system (45.5%). The concentration of folate in both serum and cerebrospinal fluid was decreased (72.7% and 63.6% respectively). Hypoimmunoglobulinemia accounted for 27.3%. Most of mutations in HFM were distributed between p. 65 and p. 68 (c.194-c.204), mainly due to insertion- or deletion-related frame shifts or generation of stop codons. Oral and parenteral folinic acid treatment was effective. Conclusion: Hereditary folate malabsorption often presented with megaloblastic anemia, abnormalities of digestive and nervous system, and hypoimmunoglobulinemia with recurrent infections. Low level of serum and CSF folate and screening SLC46A1 gene are keys to the etiologic study of the patients. Early supplement with folinic acid is beneficial to the prognosis.

Abstract
Objective: To explored the effects of lumbar dorsal muscle damage on local lumbar vertebral bone quality. Methods: Thirty SD female rats, at age of 20 weeks, were randomly divided into three groups: control group, or say pseudo surgery group, an incision in the back were performed as CNT; bilateral erector spinal muscle group in which group bilateral lumbar erector spinal muscle were removed as RESM; castration group in which bilateral ovaries were resected as OVX.After three months, bone mineral density, microscopic CT and vertebral compression test were taken in lumbar vertebral (L4-6) in turn. Results: After three months bone mineral density in RESM group was obviously lower than the control group [(0.211±0.028) g/cm2 vs(0.253±0.021) g/cm2, P<0.01], however, there was no significant difference between OVX and RESM[(0.197±0.015) g/cm2 vs(0.211±0.028) g/cm2, P>0.05]. In microscopic CT three-dimensional reconstruction and bone histomorphometry analysis, compared with control group CNT , in the experimental groups OVX and RESM, bone trabecula of vertebral bodies were more sparse, the overall number and interconnection of trabecula were less.Especially in the OVX, osteoporotic trend of trabecular network trend is more obvious.In vertebral compression test, the maximum load, energy absorption, the maximum stress and elastic modulus in both OVX and RESM were significantly reduced (P<0.01). In the RESM the above four biomechanical parameters were significantly higher than those of OVX (P<0.05). Conclusion: Integrity and vigor of paravertebral muscles would be of great significance to maintain adjacent vertebral bone quality.Resection of lumbar dorsal muscles could lead to a significant decrease of local vertebral bone quality.Damage and atrophy of lumbar dorsal muscle could cause osteoporosis of vertebral bodies.
