Abstract
Objective: To explore the value of predicting shunt-dependent hydrocephalus (SDHC) in patients with aneurysmal subarachnoid hemorrhage (aSAH) based on whole brain CT perfusion(CTP) and clinical data within 24 hours at admission. Methods: The clinical and imaging data of aSAH patients who received interventional embolization in our hospital were retrospectively collected from March 2018 to August 2022. All patients underwent one-stop whole brain CT examination within 24 hours after symptom onset, and the qualitative and quantitative CTP parameters were obtained after post-processing. Follow-up was conducted once every 2 months by consulting electronic medical records or by telephone for 6 months. According to whether SDHC occurred or not, the patients were divided into SDHC group and non-SDHC group. The differences between the two groups were compared. Logistic regression model was used to analyze and determine the predictive factors of SDHC, and the SDHC predictive model was established. The effectiveness of the predictive model was evaluated by drawing the receiver operating characteristic (ROC) curve of the subjects. Results: A total of 414 patients were included, including 132 males and 282 females, aged (59±11) years. 17.6%(73/414) patients had SDHC. There were significant differences in the occurrence of acute hydrocephalus, the World Neurosurgical League Scale (WFNS), the Hunt-Hess scale, the modified Fisher score (mFS), and the qualitative and quantitative parameters of CTP between the two groups (both P<0.001). Multivariate logistic regression analysis showed that acute hydrocephalus (OR=8.621, 95%CI: 4.237-17.542),old age (OR=1.107, 95%CI: 1.068-1.148), high mFS and high Hunt-Hess classification (OR=3.740, 95%CI: 1.352-10.342) were the risk factors of SDHC in aSAH patients, and high mean cerebral blood flow (mCBF) (OR=0.931, 95%CI: 0.885-0.980) was a protective factor of SDHC.The area under ROC curve (AUC) of the prediction model constructed by these five variables was 0.923(95%CI: 0.89-0.95), with 84.5% sensitivity and 87.7% specificity. Conclusion: The mCBF and acute hydrocephalus, age, mFS and Hunt-Hess classification within 24 hours at admission can be used to predict SDHC for aSAH patients.

Abstract
PURPOSE OF REVIEW Acute coronary syndrome (ACS) and non-alcoholic fatty liver disease (NAFLD) are two clinically common disease entities that share numerous risk factors. This review aimed to discuss the impacts of NAFLD on ACS. RECENT FINDINGS In an era of improved control of traditional risk factors, the substantial burden of cardiometabolic abnormalities has caused widespread concern. NAFLD is considered the hepatic component of metabolic syndrome, which can exert an impact on human health beyond the liver. Accumulating studies have demonstrated that NAFLD is closely related to cardiovascular disease, especially coronary artery disease. Interestingly, although recent data have suggested an association between NAFLD and the incidence and outcomes of ACS, the results are not consistent. In this review, we comprehensively summarized evidence and controversies regarding whether NAFLD is a contributor to either the development of ACS or worse outcomes in patients with ACS. The potential pathophysiological and molecular mechanisms involved in the impacts of NAFLD on ACS were also elucidated.

Abstract
Objective: To explore the clinical and biochemical discriminants of hyperandrogenism in functional hypothalamic amenorrhea (FHA). Methods: From January to September 2022, a total of 56 patients with FHA group in the Obstetrics and Gynecology Hospital of Fudan University outpatient clinic were included in this retrospective cross-sectional analysis. According to the clinical or biochemical features of hyperandrogenism, FHA patients can be divided into two subgroups, namely hyperandrogenic FHA and non-hyperandrogenic FHA. Explore the differences and its significances between hyperandrogenic FHA and non-hyperandrogenic FHA by comparing anthropometry, reproductive hormones, AMH, ultrasonic manifestation, the scores of eating attitude test, depression questionnaire and anxiety scale respectively and analyzing their correlations. Results: The age of 56 FHA patients was 15-32(23.36±4.90) years, and body mass index(BMI) was (18.91±2.49) kg/m2. The age of hyperandrogenic FHA and non-hyperandrogenic FHA was (21.76±4.40) and (24.05±5.00) (P=0.109) years old respectively, and BMI was (19.14±3.15 )and (18.81±2.18) kg/m2 (P=0.702). Compared to the non-hyperandrogenic FHA, the AMH (6.46 and 3.63 ng/ml, P=0.025) and PRL (278.78 and 149.46 mU/ml, P=0.002) levels were higher in hyperandrogenic FHA group. There was no significant difference between the hyperandrogenic and non-hyperandrogenic FHA group in body composition.GAD-7 (r=0.455, P=0.005) and PHQ-9 (r=0.664, P<0.001) were correlated with EAT-26 scores in non-hyperandrogenic FHA group, but no significant correlation was shown between PHQ-9 (r=0.091, P=0.766)、GAD-7 (r=0.304, P=0.313) and EAT-26 in hyperandrogenic FHA group. Conclusions: Some patients with FHA had clinical manifestations of hyperandrogenism and mildly elevated AMH and PRL, with underlying PCOS endocrine characteristics.

Abstract
The cornea is a transparent tissue with significant refractive and barrier functions. Corneal epithelium constitutes the first line of defense against foreign pathogens. Corneal epithelial cells interact to form a functionally selective permeability barrier. Dysfunction of this barrier leads to corneal impairment followed by a series of ocular surface diseases and even blindness. Tight junctions (TJ), located at the top of the intercellular space of corneal epithelial superficial cells, play a critical role in establishing and maintaining the barrier function. Previous studies have shown that destruction of the TJ acts as a crucial step of the occurrence and progression of multiple ocular surface diseases. Understanding the fundamental features and functions of the TJ, noticing the risk factors of TJ disruption, and clarifying the key role of TJ in the pathogenesis of various ocular surface diseases will help to better understand and treat ocular surface diseases.

Abstract
Objective: To verify the efficacy and safety of daily oral minodronate in postmenopausal women with established osteoporosis. Methods: In this randomized, double-blinded, placebo-controlled trial, 262 postmenopausal women were enrolled. Patients were randomized to receive daily oral minodronate 1 mg with supplements of 500 mg calcium and 200 U vitamin D3 (n=130) or placebo (n=132) with daily supplements of 500 mg calcium and 200 U vitamin D3, for 48 weeks. The primary endpoint was the average bone mineral density (BMD) change in the lumbar vertebrae 48 weeks post-treatment. Secondary outcome measures was the incidence of vertebral fractures. Safety assessments included the rate of adverse events. Results: At the end of 48 weeks treatment, the average BMD change rate from baseline were: full analysis set results: (3.52±4.82)% in the minodronate group and (2.00±5.74)% in the placebo group; per-protocol set results: (3.99±5.05)% in the minodronate group and (2.07±6.20)% in the placebo group; the differences were all significant (all P<0.05). Vertebral fracture occured in 3 patients (2.3%, 3/132) in the placebo group, and 1 case (0.8%, 1/130) in the minodronate group (P>0.05). The incidence of adverse events was 71.5% (93/130) in the minodronate group and 78.0% (103/132) in the placebo group (P>0.05). Conclusion: Minodronate is effective and safe in the treatment of postmenopausal osteoporosis without severe side effects.

Abstract
Objective: To investigate the diagnosis, treatment and prognosis of ureteral endometriosis with hydronephrosis. Methods: A retrospective study was performed of 92 cases diagnosed as ureteral endometriosis with surgery confirmed in Peking University First Hospital from January 2000 to January 2021. Results: The incidence of ureteral endometriosis was 0.9% (92/10 222), with an average age of (40.0±6.0) years. Among 92 cases, urological symptoms and pelvic pain including dysmenorrheal, periodic abdominal pain were the main forms of clinical characteristics, while 11 patients (12%, 11/92) were asymptomatic. All patients with ureteral endometriosis had hydronephrosis and hydroureter before surgery, hydronephrosis were left sided in 48 (52%, 48/92) patients, right sided in 39 (42%, 39/92) patients, both sided in 5 (5%,5/92) patients. The distal and middle sections of ureteral obstructions existed in 73 (79%, 73/92) patients and 19 (21%, 19/92) patients, respectively. Out of the 92 ureteral lesions 71 (77%, 71/92) patients were extrinsic lesions, 21 (23%, 21/92) patients presented intrinsic lesions. Of the 38 cases who took preoperative radionuclide renal dynamic imaging examination, there were 6 (16%, 6/38) cases of mildly damaged, 7 (18%, 7/38) cases of moderately dameged, 14 (37%, 14/38) cases of severely damaged, and 11 (29%, 11/38) cases of normal renal function. Laparotomy was decided in 25 (27%, 25/92) patients, and laparoscopic surgery in 67 (73%, 67/92) patients. In cases of ureteral surgery, ureterolysis, partial ureteral resection and ureterocystoneostomy, partial ureteral resection and end-to-end ureteral anastomosis and nephroureterectomy were undertaken in 52 (57%, 52/92), 20 (22%, 20/92), 12 (13%, 12/92) and 8 (9%, 8/92) patients separately. The median follow up was 108 months (range: 6 to 240 months). During the follow-up period, 68 (87%, 68/78) patients took urinary ultrasound after surgery, and 60 (88%, 60/68) cases of hydronephrosis disappeared, and 8 (12%, 8/68) cases were better than before. Conclusion: Most of the patients with ureteral endometriosis are impaired with renal function, and early surgical treatment could effectively relieve urinary obstruction and promote the recovery of renal function.

Abstract
Objective: To investigate the phenomenon of epileptic spasms (ES) and focal seizures (FS) in a single ictal event (FS-ES phenomenon) and to study the etiology, manifestations, and prognosis of this phenomenon. Methods: The data of the 15 neonates who had ES and FS in a single ictal event, according to video-electroencephalography (VEEG) recording in Department of Neonatology of Children's Hospital of Fudan University during the period of January 2018 to December 2019, was analyzed retrospectively. Results: Of the 15 neonates, 7 were male and 8 were female. Gestational age was 39 (32-42) weeks. Birth weight was 3 100 (1 825-3 850) g. The initial onset age of convulsions was 2 (1-10) days. The age of the first discovery of FS-ES phenomenon was 25 (14-32) days. The age of seizure-free was 7(1-27) months. All of the initial seizure types were FS. The FS-ES phenomenon of 15 patients started with FS. The FS-ES phenomenon manifested in 2 forms: FS followed by ES (12 cases), ES appeared during an FS without interrupting FS (2 cases). In 1 neonate the spasm occurred in both forms. The etiology included genetic factors (9 cases), intracranial infection (1 case), abnormal brain tissue structure (2 cases), and etiology was unknown in 3 cases. All the neonates had a poor prognosis except one. Conclusions: The FS-ES phenomenon in the neonatal period starts with FS. There are various etiologies. Etiologies of most patients are genetic factors. Most of the patients have a poor prognosis.

Abstract
Objective: To investigate the present situation of unintended pregnancy within two years postpartum and its influencing factors in China. Methods: Participants who delivered a live birth at 60 hospitals in 15 provinces in the eastern, central and western regions of China during July 2015 to June 2016 were interviewed by using structured questionnaire. Information on occurrence of unintended pregnancy within 2 years after delivery, postpartum contraceptive use, sexual resumption, breastfeeding, and women's socio-demographic characteristics, and so on, were collected. Life-table analysis, cluster log-rank tests and a 2-level Cox regression model were used for data analysis. Results: A total of 18 045 postpartum women were investigated. The cumulative 1- and 2-year unintended pregnancy rates after delivery were 5.3% (95%CI: 4.5%-6.1%) and 13.1% (95%CI: 11.3%-14.8%), respectively. Cox regression model analysis showed that the risk of unintended pregnancy within 2 years postpartum were increased in younger women, ethnic minorities, women with abortion history, and those who had a vaginal delivery with short lactation time and late postpartum contraceptive initiation (all P<0.01). The risk of postpartum unintended pregnancy was not associated with geographic regions and hospitals where women gave a birth (all P>0.05). Conclusions: In China, the risk of unintended pregnancy within 2 years after delivery is relatively high. Service institutions and service providers should improve the quality of postpartum family planning services, promote the use of high effect contraceptive methods, and educate women to use a method at the time of their sexual resumption or even before.

Abstract
BACKGROUND Human amniotic epithelial cells (hAECs) are seed cells used to treat acute myocardial infarction (AMI), but their mechanism remains unclear. METHODS We cultured hAECs and extracted exosomes from culture supernatants. Next, we established a stable AMI model in rats and treated them with hAECs, exosomes, or PBS. We assess cardiac function after treatment by echocardiography. Additionally, heart tissues were collected and analyzed by Masson's trichrome staining. We conducted the tube formation and apoptosis assays to explore the potential mechanisms. RESULTS Cardiac function was improved, and tissue fibrosis was decreased following implantation of hAECs and their exosomes. Echocardiography showed that the EF and FS were lower in the control group than in the hAEC and exosome groups, and that the LVEDD and LVESD were higher in the control group (P<0.05). Masson's trichrome staining showed that the fibrotic area was larger in the control group. Tube formation was more efficient in the hAEC and exosome groups (P<0.0001). Additionally, the apoptosis rates of myocardial cells in the hAEC and exosome groups were significantly decreased (P<0.0001). CONCLUSIONS hAECs and their exosomes improved the cardiac function of rats after AMI by promoting angiogenesis and reducing the apoptosis of cardiac myocytes.

Abstract
Objective: To analyze the related factors that affect the one-year mortality in elderly patients following hip fracture surgery. Methods: The clinical data of the elderly patients who needed a surgery for hip fracture in the Second Affiliated Hospital of Wenzhou Medical University from January 2017 to April 2018 were retrospectively analyzed. According to the inclusion criteria of the study, 489 cases were included. Then the information of patients including age, sex, Charlson comorbidity index, type of fracture, Braden score at admission, American Society of Anesthesiologists (ASA) score, length of hospital stay, type of anesthesia, whole blood cells analysis were collected. Univariate and multivariate Cox regression analyses were conducted to investigate the factors related to one-year mortality of patients. Results: After excluding 39 patients, 450 patients were finally included. Patients in this cohort study had a mortality rate of 3.33% (15/450) at 1 month, 7.78% (35/450) at half a year, and 10.89% (49/450) at 1 year after surgery. Univariate analysis showed that age, sex, ASA score, type of fracture, Charlson comorbidity index, Braden score at admission, type of analgesia, preoperative hemoglobin concentration, preoperative albumin concentration, postoperative delirium of high activity correlated with one-year mortality after surgery. Further, multivariate Cox regression analysis revealed that age>80 years old (HR=2.32, 95%CI: 1.11-4.85, P=0.025), Charlson comorbidity index ≥ 3 (HR=3.24, 95%CI:1.75-6.03, P<0.001), Braden score at admission ≤16 (HR=1.93, 95%CI:1.03-3.57, P=0.040) and postoperative delirium of high activity (HR=2.49, 95%CI:1.16-5.35, P=0.019) were risk factors for one-year mortality. Conclusions: The current study indicates that one-year mortality rate of elderly patients following hip fracture surgery is 10.89%. Meanwhile, age>80 years, Charlson comorbidity index ≥ 3, Braden score at admission ≤ 16, postoperative delirium of high activity are risk factors for one-year mortality.

Abstract
Aims: A meta-analysis was conducted to evaluate the safety and efficacy of novel oral anticoagulants (NOACs) compared with vitamin K antagonists (VKAs) in patients with left ventricular thrombus (LVT). Methods and Results: We searched PubMed, Web of Science, and Cochrane Library for cohort studies comparing the use of VKAs vs. NOACs for the treatment of LVT from the earliest date available to September 30, 2020. The predetermined efficacy and safety outcomes included thromboembolic events, resolution of LVT, clinically significant bleedings, and all-cause death. Fixed-effects model was used to estimate the pooled effects. Publication bias analyses and sensitivity analyses were conducted to check the robustness of results. A total of 6 studies enrolling 837 patients (mean age 60.2 ± 1.6 years; 77.2% were male) were included. We found no significant differences in thromboembolic events [relative risk (RR) 1.69, 95% confidence interval (CI) 0.94–3.06, P 0.08, I2 12.7%], the rate of resolution of thrombus (RR 1.08, 95% CI 0.96–1.21, P 0.21, I2 4.8%), and clinically significant bleedings (RR 0.70, 95% CI 0.37–1.32, P 0.27, I2 0%) between the VKAs and NOACs group. Additionally, no significant difference in all-cause mortality was found between the two groups (RR 1.24, 95% CI 0.79–1.96, P 0.35, I2 0.0%). Sensitivity analyses, using the “1-study removed” method, detected no significant differences. Conclusion: NOACs and VKAs have similar efficacy and safety in treating LVT, prompting the inference that NOACs are the possible alternatives of VKAs in LVT therapy.

Abstract
Objective: To evaluate the influence of preoperative fasting duration on blood volume status of pediatric patients during induction based on ultrasonic technique. Methods: One hundred and ten pediatric patients, scheduled for elective operation in the Second Affiliated Hospital & Yuying Children's Hospital, were recruited during January and October in 2018. After sedation by inhalation of sevoflurane, the maximum (expiratory) and minimum (inspiratory) diameter of inferior vena cava (IVC(max), IVC(min)) and aorta velocity-time integral (VTI) in apical five-chamber cardiac view were measured with an ultrasound machine. Respiratory variabilities of these parameters were further calculated. Furthermore, passive leg raising (PLR) test was performed and above measurements/calculations were repeated. The correlation between the duration of fasting and IVC respiratory variations index (IVC(RVI)) or aortic VTI variability (ΔVTI) was then analyzed. Results: Before PLR, IVC(max), IVC(min) and IVC(RVI) were (0.78±0.19), (0.43±0.15) cm and 0.45±0.12, respectively. After PLR, IVC(max) and IVC(min) increased to (0.94±0.20), (0.55±0.18) cm, while IVC(RVI) decreased to 0.42±0.13, the differences were statistically significant (t=15.66, 10.85, 3.14, all P<0.05). However, IVC(max), IVC(min) and IVC(RVI) were not significantly correlated with the duration of fasting analyzed by linear regression (before PLR: r=0.052, 0.163, 0.171; after PLR, r=0.062, 0.169, 0.165, all P>0.05). Before PLR, expiratory aortic VTI (VTI(max)), inspiratory aortic VTI (VTI(min)) and ΔVTI were 21±5, 17±4 and 17±8, respectively. After PLR, the VTI(max) and VTI(min) significantly increased to 23±5 and 19±4 (t=13.60, 10.43, all P<0.05), but ΔVTI was not changed significantly, which was 17±8(t=0.34, P>0.05). Linear regression analysis showed that VTI(max), VTI(min) and ΔVTI were not significantly correlated with the duration of fasting (before PLR: r=0.111, 0.100, 0.047; after PLR: r=0.003, 0.033, 0.073, all P>0.05). Further multiple linear regression analysis indicated that, age and body weight were independent factors influencing IVC(RVI) and ΔVTI before and after PLR (IVC(RVI): β=-0.441, 0.515, -0.451, 0.507; ΔVTI: β=-0.442, 0.545, -2.422, 2.850; all P<0.05). However, the duration of fasting was not correlated with IVC(RVI) and ΔVTI after adjusting the age and weight (IVC(RVI): β=0.177, 0.160; ΔVTI: β=0.037, 0.054; all P>0.05). Conclusion: Age and weight, but not preoperative fasting duration, are correlated with respiratory variabilities of inferior vena cava diameter and aortic VTI in pediatric patients.

Abstract
Objective: To evaluate the incidence of deeply infiltrating endometriosis (DIE) among patients of pelvic endometriosis confirmed by pathology and to make analysis of its clinical and pathological characteristics. Methods: From January 1, 2018 to December 31, 2018, clinical data of 240 cases of pelvic endometriosis diagnosed by laparoscopy and pathology hospitalized in Peking University First Hospital were analyzed retrospectively for the characteristics of symptoms, pelvic examination and anatomic distribution of endometriosis foci. Results: (1) Among 240 cases of pelvic endometriosis, 94 were diagnosed with DIE with an incidence of 39.2% (94/240); of them the diagnosis were made preoperatively in 44 cases (46.8%, 44/94). (2) Compared with those without DIE, patients with DIE had higher rates of secondary dysmenorrhea [53.2% (50/94) versus 38.4% (56/146), P=0.033], anal pain [43.6% (41/94) versus 28.1% (41/146), P=0.013], dyspareunea [39.4% (37/94) versus 18.5% (27/146), P=0.001] and frequent bowel movement [33.0% (31/94) versus 15.8%(23/146), P=0.002]. (3) Patients with DIE had higher rates of bad movement of uterus [21.3% (20/94) versus 6.8% (10/146), P=0.001], painful nodularity on uterosacral ligaments [26.6% (25/94) versus 6.2% (9/146), P<0.01], painful nodularity of posterior fornix [19.1% (18/94) versus 4.8% (7/146), P<0.01], blue nodule in vaginal wall [6.4% (6/94) versus 0 (0/146), P=0.003] by pelvic examination compared with those without DIE. (4) Ninety-four patients with DIE had a total of 162 nodules, of those 88 (54.3%, 88/162) located in uterosacral ligaments, 14 (8.6%, 14/162) in the rectum, 7 (4.3%, 7/162) in vaginal wall, 6 (3.7%, 6/162) in ureter, 4 in bladder (2.5%, 4/162), 2 (1.2%, 2/162) in Douglas pouch. Forty-three DIE patients (45.7%, 43/94) had more than one nodules. Patients with DIE had concomitant ovarian endometriosis in 69 cases (73.4%, 69/94), with a total of 103 endometrial cysts. (5) Patients with DIE had a higher rate of obliterated Douglas pouch [76.6% (72/94) versus 19.2% (28/146), P<0.01]. Conclusions: More than one third of patients with pelvic endometriosis have concomitant DIE with a lower rate of preoperative diagnosis. Pelvic pains, bad movement of uterus and painful nodulirity around cervix suggest the presence of DIE.

Abstract
Objective: To investigate the incidence and risk factors of ventilator-associated pneumonia (VAP) in neonatal intensive care unit (NICU), and to provide evidence for the prevention and control of VAP. Methods: A total of 1 872 neonates, who were admitted into NICU of Hunan Provincial Maternal and Child Health Hospital and subjected to mechanical ventilation from October 2016 to June 2018, were enrolled in the study. The neonates who met the diagnostic criteria of VAP were selected as the case group, and those who were treated with ventilator for 48 hours at the same time were regarded as the control group. Multivariate logistic regression model was used to analyze the related factors of VAP. Results: Of the 1 872 neonates who underwent the mechanical ventilation, the VAP occurred in 160 cases with the incidence rate of 8.5% (160 cases). The 227 specimens were collected. Gram-positive bacteria (n=116, 51.1%) were the main pathogens. The main pathogens were Staphylococcus epidermidis, Enterococcus faecalis, Acinetobacter baumannii. By Chi-square test, birth weight, birth age, Apgar score, duration of ventilator, and whether newborn mothers with pregnancy hypertension were influencing factors. The result of logistic regression analysis showed that compared with no pregnancy included hypertension, the first aid measure at birth was initial resuscitation, and the MV time ≤ 5 days, the risk factors of ventilator-associated pneumonia in neonates included: their mothers with hypertensive disorders complicating pregnancy, using of tracheal intubation and ventilator time more than 5 days. Conclusion: The incidence of VAP in neonates receiving continuous MV therapy in neonatal intensive care unit is higher. Gram-positive bacteria are the main pathogens. VAP in neonates is related to whether newborn mothers with pregnancy hypertension, MV duration and tracheal intubation.

Abstract
Many published studies have evaluated the association between the 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T (rs1801133) polymorphism and the risk of congenital heart disease (CHD); however, the specific conclusion is still controversial.To get a more accurate conclusion, we used a meta-analysis to evaluate the association between the MTHFR gene C677T polymorphism and the risk of CHD.Based on the design-based search strategy, a comprehensive literature search was conducted on PubMed, OVID, Cochrane Library, Embase, Wanfang, CNKI, and Web of Science. We selected the Newcastle-Ottawa Scale (NOS) to assess the quality of the included studies. We performed a heterogeneity test on the results of the study and calculated the combined odds ratios (ORs) and its corresponding 95% confidence intervals (95% CIs) under a random- or fixed-effect model. Subgroup analyses were conducted by ethnicity, source of controls, sample size, and genotyping method. Sensitivity analysis was used to insure authenticity of this meta-analysis result. Egger's test and Begg's funnel plot were performed to detect publication bias.Eventually, our meta-analysis included 15 eligible studies. We observed a significant correlation between the MTHFR C677T polymorphism and the development of CHD in the recessive model (OR: 1.35, 95% CI: 1.06-1.71, P = 0.006) for the overall population. In subgroups stratified by ethnicity and source of controls, subgroup analyses indicated similar associations in Asians and hospital-based groups, but not for Caucasians and population-based groups. Egger's test and Begg's funnel plot demonstrated no significant publication bias in our study.Our analysis identified that MTHFR C677T allele is a risk genetic for CHD development, especially in Asians compared with Caucasians.

Abstract
Aldehyde dehydrogenase-2 (ALDH2) rs671 G>A polymorphism can influence the activity of ALDH2 and may be associated with the risk of essential hypertension (EH). Although many previous studies have explored such a relationship, the conclusion is still controversial.The PubMed, Embase, and China National Knowledge Infrastructure databases were searched on the ALDH2 gene and EH. We used the Newcastle-Ottawa Scale to evaluate the quality of the study. Then we calculated the strength of relationship between ALDH2 rs671 mutation and EH by utilizing odds ratios and 95% confidence intervals. Besides, subgroup analysis and sensitivity analysis were performed and the publication bias was assessed.There were 12 studies containing 8153 cases and 10,162 controls. Our meta-analysis showed significant association between ALDH2 rs671 polymorphism and EH in four genetic models (the allele model, the homozygote model, the heterozygote model, and the dominant model), whereas it did not indicate this connection in the recessive model. However, a trend of decreased risk still could be seen. Furthermore, we also found an obvious association between rs671 mutation and the risk of EH in the male group than in the female group in all five genetic models.We concluded that ALDH2 rs671 G>A polymorphism may decrease the risk of EH. Furthermore, susceptibility to EH reduced in males but not in females. As a variant in ALDH2, rs671 G>A could be an attractive candidate for genetic therapy of EH. In addition, more case-control studies should be conducted to strengthen our conclusion and evaluate the gene-gene and gene-environment interactions between the ALDH2 gene and EH.

Abstract
BACKGROUND It has been reported the rs10757274 SNP (present on locus 9p21 in the gene for CDKN2BAS1) might be associated with susceptibility to coronary artery disease (CAD). Owing to mixed and inconclusive results, we conducted a meta-analysis to investigate the association between rs10757274 polymorphism and the risk of CAD. OBJECTIVES The present study aimed to investigate the relationship between rs10757274 polymorphism and the risk of CAD. METHODS All studies of the rs10757274 SNP with CAD that were published between 2007 and 2018 were retrieved from the PubMed database. Meta-analysis was performed with Stata 14.0 software. The effect size of the rs10757274 SNP with CAD risk was assessed based on the odds ratios (ORs) with calculation of 95% confidence interval (CI). RESULTS Eleven studies including 52,209 subjects (cases: 7990, controls: 44,219) were included in the final data combination. Pooled overall analyses showed that rs10757274 (allele model: P < .001; dominant model: P < .001; recessive model: P < .001; Heterozygote codominant: P = .002; Homozygote codominant: P < .001) polymorphisms were significantly associated with the likelihood of CAD. Significant heterogeneity between individual studies appears in all 5 models. Further subgroup analyses revealed that rs10757274 polymorphisms were all significantly correlated with the likelihood of CAD and no heterogeneity were observed in West Asians. CONCLUSIONS Our findings indicated that rs10757274 polymorphisms may serve as genetic biomarkers of CAD, especially in West Asians.

Abstract
The study was initiated to evaluate constructed wetland technology as a method for treating alkaline (pH 8.0-8.6) drainage high in Al, Mo, V, As and Ga originating from bauxite residue storage areas. Pilot-scale horizontal flow constructed wetlands were operated over a 40-week period using three filter materials (granitic gravel, bauxite and alum water treatment sludge), and half of the wetlands were planted with Phragmites australis and the other half left unplanted. Gravel was the least effective medium for removing the target elements, while of the two active media, water treatment sludge was more effective than bauxite. Plants removed only small amounts of elements into their above- and below-ground dry matter (0.4-4.9% of that added). Nonetheless, the presence of plants greatly increased the effectiveness of all three media since their presence decreased effluent pH values by 0.5-1.3 pH units and that of the filter media by 0.4 pH units. Removal of elements followed the order Al > Ga > V > As > Mo. For planted wetlands, total elemental removal ranged from 18 to 98% for gravel, 80 to 99% for bauxite, and 93 to 99% for water treatment sludge. The lowest removal was for Mo (ranging from 18% for gravel to 93% for water treatment sludge) and the highest for Al (ranging from 98% in gravel to 99% in water treatment sludge). A sequential fractionation scheme for As, V and Mo on filter material at the end of the experiment showed that for bauxite and water treatment sludge, V and As were concentrated in the NaOH extractable fraction while Mo was concentrated in the less strongly adsorbed NaHCO3 extractable fraction. It was concluded that a constructed wetland with water treatment sludge as an active filter material is an effective technology for removal of the target elements from the alkali drainage.

Abstract
Background The SYNTAX score for decision makings or outcome predictions in coronary artery disease does not account for the variations in the coronary anatomy, which is a clear fallacy for patients with less typical anatomy than suggested by the SYNTAX score. The current study aimed to derive a new coronary angiographic scoring system accommodating the variability in the coronary anatomy. Methods The 17-myocardial segment model and laws of competitive blood supply and flow conservation were utilized to derive this new scoring system. Results We obtained 6 types of RCA dominance, 3 types of diagonal size and 3 types of left anterior descending artery (LAD) length, which together resulted in a total of 54 patterns of coronary artery circulation to account for the variability in the coronary anatomy among individuals. A Coronary Artery Tree description and Lesion EvaluaTion (CatLet) angiographic scoring system has been designed based on the above-mentioned reclassification scheme (htpp://www.catletscore.com, IE browser is required to run this calculator). Conclusions This new CatLet angiographic scoring system accommodated the variability in the coronary anatomy and standardized the collection of the coronary angiographic data, which could facilitate the comparison and exchange of these data between different catheter labs. Its utility for predicting the clinical outcomes and standardizing the angiographic data collection will be investigated in a series of clinical trials enrolling "all-comers" with coronary artery disease (CAD).

Abstract
Objective: To evaluate the effects of parthenolide on estradiol-synthesizing enzyme, steroidogenic acute regulatory protein (StAR), and ER isoforms,VEGF in human endometriotic stromal cells. Methods: Primary endometriotic stromal cells were treated with different concentrations (1, 5, 10 and 20 μmol/L) of parthenolide. The mRNA of StAR, ER isoforms (ERα and ERβ), PR, vascular endothelial growth factor (VEGF), interleukin-6 (IL-6), tumour necrosis factor-α (TNFα), tumour necrosis factor receptor (TNFR) 1, TNFR2 were measured by real-time PCR. The levels of estradiol and progesterone in the cell supernatant were measured by ELISA. Results: Different concentrations of parthenolide could up-regulate the mRNA of StAR in primary endometriotic stromal cells (F=5.722, P<0.05); the mRNA of StAR in the group of 20 μmol/L was significantly higher than that of the control group [2.6±0.3 versus 1.0, P<0.01]. Different concentrations of parthenolide could down-regulate the mRNA of ERα (F=6.921, P<0.01); the mRNA of ERα in the group of 20 μmol/L and 10 μmol/L were significantly lower than those of the control group [0.2±0.3 versus 0.3±0.3 versus 1.0, all P<0.05]. Different concentrations of parthenolide could down-regulate the ratios of ERα/ERβ mRNA levels (F=4.209, P<0.05). Different concentrations of parthenolide could up-regulate the mRNA of VEGF and TNFR1 (F=10.964, P<0.01; F=7.286, P<0.01). There were no statiscal significances with different concentrations of parthenolide on the mRNA of ERβ, PR, IL-6, TNFα and TNFR2, and the levels of estradiol and progesterone in the cell supernatant (all P>0.05). Conclusions: Parthenolide may regulate the expression of estradiol-synthesizing enzyme, ER isoforms and angiogenesis in endometriotic stromal cells. Parthenolide may promote the development of endometriosis.

Abstract
Objective: To compare the expression of leukemia inhibitory factor (LIF), interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) in tissue and fluid samples from patients with endometriosis, and investigate whether LIF and IL-6 regulate VEGF in human endometriotic stromal cells (ESC). Methods: The levels of VEGF, LIF, IL-6 in serum, peritoneal fluid of patients with and without endometriosis were measured by ELISA. The mRNA of these three factors in the ectopic and eutopic endometrial tissue and stromal cells were measured by real-time PCR. ESC derived from ovarian endometriomas were cultured using the method of primary cell culture with LIF and IL-6, and the level of VEGF mRNA and protein were measured by the method of real-time PCR and ELISA respectively. Results: VEGF and IL-6 concentration were 1.2 and 1.3 times higher in the serum of patients with endometriosis than in the control group [(94±19) versus (78±17) ng/L; (45±14) versus (35±9) ng/L; all P<0.05]. VEGF and IL-6 concentration were 1.2 and 1.4 times higher in the peritoneal fluid of patients with endometriosis than in the control group [(110±25) versus (91±21) ng/L; (69±20) versus (49±15) ng/L; all P<0.05]. VEGF and IL-6 concentrations in peritoneal fluid of patients with endometriosis were 1.2 and 1.5 times higher than in serum (all P<0.01). VEGF, LIF and IL-6 mRNA expression were 2.2, 8.6, 44.7 times higher in ESC compared with the matching eutopic endometrial stromal cells (all P<0.01). LIF and IL-6 mRNA were 2.0 and 64.8 times higher in ectopic endometrial tissue than the matching eutopic endometrial tissue (all P<0.05).ESC cultured with LIF, IL-6 and LIF+IL-6 induce VEGF protein secretion [(106±18), (124±30), (140±27) ng/L] by 1.3, 1.5 and 1.7 times (all P<0.05). Conclusion: Overexpression of LIF and IL-6 may synergistically contribute to upregulation of VEGF in ESC and promote development of endometriosis.

Abstract
Objective: To measure the uterine volume by ultrasonic imaging in nullipara patients with endometriosis and analyze its clinical significance. Methods: From July 1st, 2016 to August 1st, 2017, 107 cases of nullipara patients with endometriosis hospitalized in Peking University First Hospital were selected as endometriosis group. Among 107 cases, 59 cases were in proliferative phase of menstrual cycle, 48 cases were in secretory phase; and 10 cases had an abortion history.Totally 101 cases of patients without endometriosis operated for other benign disease during the same period were chosen as the control group. All patients underwent laparoscopic surgery, and the diagnosis was confirmed by pathology. The uterine size was measured by transvaginal or transrectal color Doppler ultrasound, and the uterine volume was calculated according to the known formula. Results: The uterine volume of the endometriosis group [(69±26) cm(3)] was larger than that of the control group [(54±18) cm(3), P<0.01]. In the endometriosis group, the uterine volume of patients with pregnant history [(78±34) cm(3)] was larger than that of patients without pregnant history [(68±25) cm(3)]. The endometrial thickness in endometriosis group was higher than that of the control group [(9.1±3.5) versus (7.8±2.9) mm, P<0.05], and positively correlated with the uterine volume (r=0.39, P<0.05). The hemoglobin in endometriosis group was lower than that in the control group [(124±12) versus (131±10) g/L, P<0.01], and was negatively correlated with the uterine volume in the two groups (r(endometriosis)=-0.12, r(control)=-0.21; both P<0.05).The uterine volume of dysmenorrhea patients in the endometriosis group [(73±28) cm(3)] was greater than that of patients without dysmenorrhea [(62±19) cm(3), P<0.01]; both uterine volumes of patients with and without dysmenorrhea in endometriosis group were larger than those of patients with or without dysmenorrhea in the control group (P<0.05). The degree of dysmenorrhea in endometriosis group was positively correlated with the uterine volume (r=0.20, P=0.042). The uterine volume of stage Ⅳendometriosis patients [(79±30) cm(3)] was greater than that of stage Ⅲ patients in endometriosis group [(58±14) cm(3), P<0.01]. Conclusion: Patients with endometriosis are of increased uterine volume, which may be related to dysmenorrhea, menorrhagia and infertility.

Abstract
Objective: To elucidate whether metformin could regulate the mRNA expression level of estrogen synthetase and ER in human uterine leiomyoma tissues. Methods: (1) Seventeen pairs of uterine leiomyoma tissues and adjacent myometrium (>2 cm) were collected from patients underwent hysterectomy in Peking University First Hospital between December 2016 and January 2017. Real-time PCR was used to measure the mRNA expression level of estrogen synthetase [including cytochrome P450 cholesterol side chain cleavage enzyme (P450scc), cytochrome P450 17α-hydroxylase (P450c17), 3-beta-hydroxysteroid dehydrogenase type 2 (3β-HSD-2), 17-beta-hydroxysteroid dehydrogenase type 1 (17β-HSD-1) and aromatase cytochrome P450 (P450arom)] and ER (including ERα and ERβ) in the uterine leiomyoma tissues and adjacent myometrium. (2) Uterine leiomyoma cells derived from uterine leiomyoma tissues were identified by immunocytochemistry method and cultured to the third generation. The treatment groups were cultured with different concentrations of metformin (10, 50 and 100 μmol/L) for 48 hours, and the control group was cultured with deionized water for 48 hours. The mRNA expression level of estrogen synthetase and estrogen receptor subtypes were measured by real-time PCR. Results: (1) P450scc, P450c17, 3β-HSD-2, 17β-HSD-1, P450arom mRNA median expression levels were 112, 4, 13, 42 and 194 in the uterine leiomyoma tissues, and were respectively 114, 5, 11, 32 and 6 in the myometrium. Compared to those of the myometrium, 3β-HSD-2 and P450arom mRNA expression levels in the uterine leiomyoma tissue were significantly higher (P<0.05), while there were no significant change of mRNA expression levels among P450scc, P450c17 and 17β-HSD-1 (P>0.05). ERα and ERβ mRNA median expression levels were 208 and 116 in the uterine leiomyoma tissues, and were 24 and 95 in the myometrium. Compared to that of the myometrium, ERα mRNA level in the uterine leiomyoma tissue was significantly higher (P=0.001), while there were no significant change of ERβ mRNA level (P=0.193). (2) After cultured with different concentrations of metformin (10, 50 and 100 μmol/L), the P450arom mRNA levels in the uterine leiomyoma tissues were 9±4, 8±5 and 8±3 respectively in the treatment groups and was 16±5 in the control group. Compared to that of the control group, P450arom mRNA expression levels in the treatment groups were significantly declined (P<0.05). There were no significant different change of mRNA expression levels among 3β-HSD-2, ERα and ERβ between the treatment groups and the control group (P>0.05). Conclusions: Metformin could down-regulate the mRNA expression level of aromatase in the uterine leiomyoma cells. These results indicate that metformin may inhibit the local estrogen synthesis and therefore suppress the development of uterine leiomyoma.

Abstract
BACKGROUND Research interest in endothelial nitric oxide synthase(eNOS) polymorphisms and atrial fibrillation (AF) has grown in last recent years, but the results of individual studies are inconsistent due to their small sample sizes. MATERIAL AND METHODS We searched databases for eligible studies on eNOS and AF, extracted the relevant data, and rigorously screened them according to inclusion and exclusion criteria. Then, we evaluated the study quality according to the Newcastle-Ottawa scale score, and we pooled the odds ratios (ORs) and 95% confidence intervals (CIs) by using a random-effects model or fixed-effects model based on inter-study heterogeneity. In addition, we performed subgroup analysis and sensitivity analysis and assessed publication bias. RESULTS According to the inclusion and exclusion criteria, we finally found 8 studies in this search. The recessive (OR=0.81; 95% CI=0.67 to 0.97; p=0.988; I²=0.0%) model showed that the eNOS 786T/C polymorphism was relevant to AF. We also found that the eNOS 786T/C polymorphism decreases the risk of AF, especially in white people (OR=0.81; 95% CI=0.67 to 0.97; P=0.023 for recessive model) and in the control population (OR=0.79; 95% CI=0.65 to 0.97; P=0.022 for recessive model). We found no obvious publication bias. CONCLUSIONS The eNOS gene loci 786T/C polymorphism is relevant to the risk of AF. Our results suggest that the 786T/C polymorphism significantly decreases AF risks in white people and control populations. Larger studies are required for further evaluation.

Abstract
Objective: To analyze the expression microarray data in the public databases of intracranial aneurysms (IA) using bioinformatics, and to provide important information for the study of disease mechanisms. Methods: Gene co-expression network was constructed by weighted gene co-expression network analysis (WGCNA) based on the dataset (GSE75436) and pivot genes were identified. Using the online tool DAVID (Database for Annotation, Visualization, and Integrated Discovery) to perform GO function enrichment and KEGG path analysis on modules highly related to IA. Results: Three IA-related modules were screened out, and 14 pivot genes (COL3A1, SPARC, CDH11, COL5A1, HOPX, CLEC11A, GALNT10, ADAMTS2, CEMIP, KIAA1755, COL11A1, ZIC2, CDKN2A, and LINC00460) in the brown module were identified; the analysis of GO showed that the brown module was mainly enriched in extracellular matrix organization, extracellular matrix organization, cell adhesion and other biological processes; the analysis of KEGG indicated that the brown module involved in ECM-receptor interaction, Focal adhesion, protein digestion and absorption, PI3K-Akt signaling pathway. Conclusion: Based on WGCNA, we identified modular and pivotal genes that are critical to the development of IA, and they may become potential biomarkers and/or therapeutic targets.

Abstract
BACKGROUND Rapid progress has been made in research of cadmium-zinc-telluride (CZT) technology in the last few years, which might serve as a new method to diagnose coronary artery disease. However, compared with coronary angiography, the diagnostic value of CZT is still controversial. We aimed to evaluate diagnosis value of coronary angiography versus CZT in coronary artery disease. METHODS We searched the database for eligible researches associated with CZT- myocardial perfusion imaging (MPI) and invasive coronary angiography, extracted the relevant data, and rigorously screened it according to the inclusion and exclusion criteria. The accuracy indicators included sensitivity, specificity, accuracy, positive and negative likelihood ratios. RESULTS According to the inclusion and exclusion criteria, we finally found 20 studies containing 2350 patients in this search. Pooled results showed that sensitivity of CZT-MPI was 0.84% and 95% confidence interval (95% CI): 0.78 to 0.89, specificity was 0.72, 95% CI (0.62-0.76), the specificity was lower apparently. The positive likelihood ratio was 3.0, 95% CI (2.4-3.8), the negative likelihood ratio was 0.22, 95% CI (0.16-0.31), diagnostic odds ratio was 14, 95% CI (7.84-17.42). CONCLUSION This meta-analysis showed that CZT-MPI had satisfactory sensitivity and specificity for diagnosing coronary artery disease. Larger studies are required for further evaluation.

Abstract
A 32-week leaching column study was carried out in the greenhouse to investigate the effects of incorporation of gypsum, cattle manure, biosolids, gypsum plus cattle manure and gypsum plus biosolids into the topsoil layer (0-10 cm) on growth of Rhodes grass, and on root distribution and chemical and microbial properties in the topsoil and subsoil (10-30 cm) layers of seawater neutralized bauxite residues. The columns were leached for a period of 8 weeks prior to sowing Rhodes grass and during that time the bulk of the salts accumulated during seawater neutralization were leached out. The main cation leached was Na+ and the main balancing anions were Cl- and SO42-. During this period the pH of leachates rose from 7 to 8 up to 9-10. At the end of the study, exchangeable Na and pH were lowered in the surface horizon by all treatments with a combination of gypsum plus organic amendments having the greatest effect. The latter treatments also caused a significant decrease in pH, extractable Al and exchangeable Na in the subsoil. Rhodes grass dry matter production followed the order Control < gypsum < cattle manure = gypsum plus cattle manure < biosolids = gypsum plus biosolids. Growth of roots into the subsoil layer was inhibited in the Control and gypsum treatments but when organic amendments were applied, 50% or more of root dry matter was recovered in the subsoil layer. It was concluded that incorporating a combination of gypsum and organic matter into the surface soil is an effective strategy for revegetation of bauxite residue.

Abstract
When low-cost adsorbents are being used to remove contaminant ions (e.g. arsenate, vanadate, and molybdate) from wastewater, competitive adsorption/desorption are central processes determining their removal efficiency. Competitive adsorption of As, V, and Mo was investigated using equimolar oxyanion concentrations in single, binary, and tertiary combinations in adsorption isotherm and pH envelope studies while desorption of previously adsorbed oxyanions was examined in solutions containing single and binary oxyanion combinations. The low-cost adsorbent materials used were alum water treatment sludge (amorphous hydroxy-Al) and bauxite ore (crystalline Al oxides). Adsorption isotherm and pH envelope studies showed that Mo had only a small effect in decreasing adsorption of As and V but V and As had substantial and similar effects in reducing adsorption of the other. As had a greater effect than V in reducing adsorption of Mo and it was concluded that the affinity of oxyanions for the surfaces of water treatment sludge and bauxite followed the order As > V >> Mo. In 0.3 M NaCl electrolyte, desorption of previously adsorbed oxyanions amounted to 0.3-3.4% for V and As, and 11-20% for Mo. As had approximately four times greater effect than Mo in increasing desorption of V while V had about three times the effect of Mo in increasing desorption of As. Thus, the order of oxyanions in inducing desorption of the other oxyanions (i.e. As on V and As) was the same as that for adsorption selectivity: As > V >> Mo. Water treatment sludge was a more effective adsorbent than bauxite because it had a greater adsorption capacity for all three anions and, in addition, they were held more strongly so desorption in the background electrolyte was proportionately less. It was concluded that at similar molar concentrations, arsenate would tend to reduce adsorption of vanadate as well as displace vanadate already held on adsorbent surfaces while both anions will compete effectively with molybdate. The limiting factor for simultaneous removal of As, V, and Mo from multielement solutions by adsorption will therefore be the removal of Mo.

Abstract
BACKGROUND More susceptibility genes have been proved to be associated with coronary heart disease (CHD). The goal of our study is to evaluate the association between the R262W polymorphism of SH2B3 gene and risk of CHD. METHODS A systematic search was conducted using PubMed, Embase, Web of Science, CNKI, and WanFang databases up to March of 2018. The data of individual study were individually performed by 2 reviewers. The meta-analysis was performed by Stata software and expressed by the pooled odds ratio (OR) and the 95% confidence interval (CI), which were calculated by specific model according to heterogeneity. RESULTS Our research was based on 12 studies involving 25,845 patients and 68,910 healthy controls. Significant association between the variant R262W and CHD were found in overall populations (OR = 1.12, 95%CI = 1.09-1.15, P = .389, I = 5.4%), but not found in Asian (OR = 1.05, 95%CI = 0.98-1.12, I = 0.0%) in subgroup analysis by ethnicity. In another subgroup analysis, when classified into CHD and myocardial infarction (MI), there was a significance association between R262W and CHD (OR = 1.11,95% CI = 1.07-1.15, I = 13.5%) and MI (OR = 1.13, 95%CI = 1.08-1.18, I = 0.0%). The Begg's funnel plot revealed no significant publication bias. CONCLUSIONS The R262W polymorphism is associated with risk of CHD or MI in Europeans, but not in Asians.

Abstract
Low temperature is an important abiotic stress that negatively affects morphological growth and fruit development in melon (Cucumis melo L.). Chilling stress at the seedling stage causes seedling injury and poor stand establishment, prolonging vegetative growth and delaying fruit harvest. In this study, association mapping was performed for chilling tolerance at the seedling stage on an expanded melon core collection containing 212 diverse accessions by 272 SSRs and 27 CAPSs. Chilling tolerance of the melon seedlings was evaluated by calculating the chilling injury index (CII) in 2016 and 2017. Genetic diversity analysis of the whole accession panel presented two main groups, which corresponded to the two subspecies of C. melo, melo, and agrestis. Both the subspecies were sensitive to chilling but with agrestis being more tolerant. Genome-wide association study (GWAS) was conducted, respectively, on the whole panel and the two subspecies, totally detecting 51 loci that contributed to 74 marker-trait associations. Of these associations, 35 were detected in the whole panel, 21 in melo, and 18 in agrestis. About half of the associations identified in the two subspecies were also observed in the whole panel, and seven associations were shared by both the subspecies. CMCT505_Chr.1 was repeatedly detected in different populations with high phenotypic contribution and could be a key locus controlling chilling tolerance in C. melo. Nine loci were selected for evaluation of the phenotypic effects related to their alleles, which identified 11 elite alleles contributing to seedling chilling tolerance. Four such alleles existed in both the subspecies and six in either of the two subspecies. Analysis of 20 parental combinations for their allelic status and phenotypic values showed that the elite alleles collectively contributed to enhancement of the chilling tolerance. Tagging the loci responsible for chilling tolerance may simultaneously favor dissecting the complex adaptability traits and elevate the efficiency to improve chilling tolerance using marker-assisted selection in melon.

Abstract
Insufficient supply of Met and choline (Chol) around parturition could compromise hepatic metabolism and milk protein synthesis in dairy cows. Mechanistic responses associated with supply of Met or Chol in primary liver cells enriched with hepatocytes (PHEP) from cows have not been thoroughly ascertained. Objectives were to isolate and culture PHEP to examine abundance of genes and proteins related to transmethylation, transsulfuration, and cytidine 5'-diphosphocholine (CDP-choline) pathways in response to Met or Chol. The PHEP were isolated from liver biopsies of Holstein cows (160 d in lactation). More than 90% of isolated cells stained positively for the hepatocyte marker cytokeratin 18. Cytochrome P450 (CYP1A1) mRNA abundance was only detectable in the PHEP and liver tissue compared with mammary tissue. Furthermore, in response to exogenous Met (80 μM vs. control) PHEP secreted greater amounts of albumin and urea. Subsequently, PHEP were cultured with Met (40 μM) or Chol (80 mg/dL) for 24 h. Compared with control or Chol, mRNA and protein abundance of methionine adenosyltransferase 1A (MAT1A) and phosphatidylethanolamine methyltransferase (PEMT) were greater in PHEP treated with Met. The mRNA abundance of S-adenosylhomocysteine hydrolase (SAHH), betaine-homocysteine methyltransferase (BHMT), and sarcosine dehydrogenase (SARDH) was greater in Met-treated PHEP compared with control or Chol. Compared with control, greater expression of 5-methyltetrahydrofolate-homocysteine methyltransferase (MTR), betaine aldehyde dehydrogenase (BADH), and choline dehydrogenase (CHDH) was observed in cells supplemented with Met and Chol. However, Chol led to the greatest mRNA abundance of CHDH. Abundance of choline kinase α (CHKA), choline kinase β (CHKB), phosphate cytidylyltransferase 1 α (PCYT1A), and choline/ethanolamine phosphotransferase 1 (CEPT1) in the CDP-choline pathway was greater in PHEP treated with Chol compared with control or Met. In the transsulfuration pathway, mRNA and protein abundance of cystathionine β-synthase (CBS) was greater in PHEP treated with Met compared with control or Chol. Similarly, abundance of cysteine sulfinic acid decarboxylase (CSAD), glutamate-cysteine ligase, catalytic subunit (GCLC), and glutathione reductase (GSR) was greater in response to Met compared with control or Chol. Overall, these findings suggest that transmethylation and transsulfuration in dairy cow primary liver cells are more responsive to Met supply, whereas the CDP-choline pathway is more responsive to Chol supply. The relevance of these data in vivo merit further study.

Abstract
Seawater neutralization is a technique that can be used to treat bauxite residue prior to its storage but, as yet, no attempts have been made to revegetate it. Seawater neutralized bauxite residue was found to have a pH1:5 of 9.3 and to be highly saline (EC1.5 16.5 dS m-1). After leaching pH1:5 rose to 9.7 and the residue was still highly sodic (ESP = 64-69%). Addition of 1% gypsum, prior to leaching, arrested this increase in pH while with 5% gypsum addition the pH1:5 was lowered to 8.9. Addition of 5% gypsum also reduced ESP to 38% and increased watercress germination in the residue from 58% in control treatments to 88%. The major ions in leachates were Na+ and Cl- and gypsum application increased the quantities of Na+, Ca2+ and SO42- leached. Addition of 6% biosolids or 6% poultry manure added exchangeable cations to the mud and lowered ESP by 5-11%.The EC was 2.8-3.7 (mean 3.1) times higher and pH 0.2-0.7 (mean 0.43) units lower in saturation paste compared with 1:5 soil:water extracts. Addition of amendments had only small effects on physical properties. While organic C content was increased more by biosolids than poultry manure addition the reverse was the case for soluble organic C, microbial biomass C and basal respiration. It was concluded that although seawater neutralization initially lowers the pH of bauxite residues it is unlikely to increase the ease with which they can be revegetated.

Abstract
Laboratory and greenhouse experiments were carried out to investigate the chemical, physical, and microbial properties of seawater-neutralized bauxite residues and the effects of additional leaching (1 pore volume of deionized water versus an additional 6 pore volumes) and amendment with gypsum (5%) and/or cattle manure (6%) on its properties and on the growth of Rhodes grass (Chloris gayana). Additional leaching resulted in a decrease in EC, exchangeable Na, SAR, and ESP. For unamended control treatments, additional leaching induced a rise in pHSE from 8.5 to 9.6 and pH1:5 from 9.1 to 10.1 due to dissolution of residual alkalinity. Addition of gypsum arrested this pH increase resulting in a final pHSE of 7.5 and pH1:5 of 8.8. In control treatments, additional leaching resulted in a pronounced decrease in Rhodes grass yields. However, in gypsum and cattle manure-amended treatments, it led to substantial yield increases and decreases in tissue Al and Na concentrations and increased K/Na ratios. Upon drying for the first time, bauxite residue was shown to contract and form a solid massive structure. The aggregates formed from crushing this material were water stable (as measured by wet sieving). Additions of cattle manure or gypsum to residue aggregates did not affect pore size distribution. Addition of cattle manure increased organic C and microbial biomass C content and basal respiration rate while additional leaching increased basal respiration and metabolic quotient. It was concluded that a combination of drying and crushing the residue, amending it with gypsum and organic manure followed by extensive leaching results in the formation of a medium that supports plant growth.

Abstract
Painful diabetic neuropathy (PDN) is a common and troublesome diabetes complication. Protein kinase C (PKC)-mediated dorsal root ganglia (DRG) P2X3 receptor upregulation is one important mechanism underlying PDN. Accumulating evidence demonstrated that electroacupuncture (EA) at low frequency could effectively attenuate neuropathic pain. Our previous study showed that 2-Hz EA could relieve pain well in PDN. The study aimed to investigate whether 2-Hz EA relieves pain in PDN through suppressing PKC-mediated DRG P2X3 receptor upregulation. A 7-week feeding of high-fat and high-sugar diet plus a single injection of streptozotocin (STZ) in a dose of 35 mg/kg after a 5-week feeding of the diet successfully induced type 2 PDN in rats as revealed by the elevated body weight, fasting blood glucose, fasting insulin and insulin resistance, and the reduced paw withdrawal threshold (PWT), as well as the destructive ultrastructural change of sciatic nerve. DRG plasma membrane P2X3 receptor level and DRG PKC expression were elevated. Two-hertz EA failed to improve peripheral neuropathy; however, it reduced PWT, DRG plasma membrane P2X3 receptor level, and DRG PKC expression in PDN rats. Intraperitoneal administration of P2X3 receptor agonist αβ-meATP or PKC activator phorbol 12-myristate 13-acetate (PMA) blocked 2-Hz EA analgesia. Furthermore, PMA administration increased DRG plasma membrane P2X3 receptor level in PDN rats subject to 2-Hz EA treatment. These findings together indicated that the analgesic effect of EA in PDN is mediated by suppressing PKC-dependent membrane P2X3 upregulation in DRG. EA at low frequency is a valuable approach for PDN control.

Abstract
This study investigated the factors affecting the semen traits of boars in Southern China. A total of 172,408 ejaculates of boars from 9 AI centers were collected from January 2013 to May 2016. A linear growth model was used to analyze the effects of leve1 1 (boar breed, age, season, and boar age at herd entry) and level 2 (housing type) factors on semen quality. The intraclass correlation coefficients of semen volume, total sperm number, functional sperm number, sperm concentration, motility, and abnormal sperm were 0.62, 0.62, 0.61, 0.60, 0.54, and 0.70, respectively. Boars reared in ordinary houses had lower total and functional sperm numbers than those reared in air filtration houses ( < 0.05). The functional sperm number of Duroc boars was lower than that of Landrace and Yorkshire boars ( < 0.05). The total and functional sperm numbers were lowest from May to September and peaked at the age of 34.1 and 37.7 mo, respectively. Furthermore, boars aged 8 and 9 mo at herd entry had greater functional sperm numbers than those aged 5, 6, 7, and 12 mo at herd entry ( < 0.05), whereas no significant difference was observed between boars aged 8 mo and boars aged 9 mo at herd entry ( > 0.05). In conclusion, the linear growth model is suitable for longitudinal data analysis. To improve boar breeding, sunstroke prevention in the early spring should be given greater attention. Importantly, 8 mo appears to be the most suitable age for boar introduction, especially for Duroc boars.

Abstract
The effects of increasing pH on the adsorption and extractability of Si in two Si-deficient Australian sugarcane soils was investigated and the effects of increasing rates of fertilizer Si (as blast furnace slag) on pH and extractable Si were also examined. Equilibrium studies showed that maximum adsorption of Si by the two soils occurred in the pH range 9-10. When soil pH was increased from 5.0 to 6.5, subsequent adsorption of Si by the two soils, as measured by adsorption isotherms, increased. After incubation with progressive lime additions there was a decline in CaCl2- extractable Si due to its increased adsorption and an increase in acid (H2SO4- and acetic acid)-extractable (mainly adsorbed) Si. The increase in acid extractable Si was greater than the decrease in CaCl2- extractable Si suggesting a supply from an additional source. Alkali (Na2CO3 and Tiron)-extractable Si decreased greatly with increasing pH suggesting dissolution of the amorphous (mainly biogenic) pool of silica was occurring with increasing pH. When increasing rates of slag were incubated with the soils, pH, CaCl2- and acid- extractable Si were all increased because upon dissolution slags release both silicic acid and OH- ions. There was, therefore, a positive relationship between extractable Si and soil pH. However, Na2CO3-and Tiron-extractable Si decreased with increasing slag rates (and increasing soil pH) suggesting dissolution of the biogenic pool of soil Si. It was concluded that future research needs to examine the desorption potential of adsorbed Si and the effects of liming on dissolution of the biogenic pool of soil silica under field conditions.

Abstract
Generation of human cardiomyocytes from cells derived from various sources, including skin biopsy, has been made possible by breakthrough advances in stem cell research. However, it is attractive to build up a negligibly invasive way to create induced pluripotent stem (iPS) cells. In this study, we created iPS cells from human urine-derived epithelial cells by gene transduction using lentiviral vectors in a totally noninvasive manner. Then, we induced the differentiation of iPS cells into functional cardiomyocytes both in vitro and in vivo Action potentials were recorded in putative cardiomyocytes and spontaneous beating cells were observed. Our results offered an alternative method to generate cardiomyocytes in a totally noninvasive manner from an easily accessible source. The availability of urine and its potent reprogramming characteristics will provide opportunities for the use of cells with specific genotypes to study the pathogenesis and molecular mechanisms of disease in vitro.

Abstract
Recently a large number of investigations have implicated the association between the chemokine CXC ligand 12 gene polymorphism (rs1746048) and risk of coronary heart disease (CHD), but the results remain debatable. The aim of our study was to provide more compelling evidence for the relationship between rs1746048 and CHD risk. Studies eligible for this meta-analysis were identified through electronic search of PubMed, EMBASE, and CNKI. Two authors performed independent literature review and study quality assessment by using the Newcastle-Ottawa Scale checklist. The odds ratios (ORs) with 95% confidence intervals (CIs) were pooled in a specific genetic model to assess the association. The meta-analysis of 48,852 patients and 64,386 controls from 12 studies showed that patients with rs1746048 had 1.11 times of high risk in developing CHD (OR = 1.11; 95% CI = 1.09-1.14; P < .005; I = 35.8%). The increased risk of CHD was also found in both Asian (OR = 1.07; 95%CI = 1.02-1.12; P < .005; I = 40.6%) and Caucasian populations (OR = 1.14; 95% CI = 1.10-1.18; P < .005; I = 22.2%). The results of our meta-analysis suggested that chemokine CXC ligand 12 gene polymorphism (rs1746048) may be linked with susceptibility to CHD.

Abstract
BACKGROUND Previous case-control studies on association between KCNE1 G38S polymorphism and risk of atrial fibrillation (AF) have been published but because of the conflicting results and small sample size of individual studies, the consolidated result is still controversial. OBJECTIVES The aim of this study was to explore the relationship between KCNE1 G38S polymorphism and risk of AF. METHODS We performed a comprehensive literature search on PubMed, Embase, OVID, Web of Science, Wan Fang, and CNKI databases up to March 10, 2017 in English and Chinese languages. Two of the authors individually extracted study data and assessed the study quality using Newcastle-Ottawa scale. Odds ratios (ORs) and 95% confidence intervals (CIs) were combined in different genetic models for evaluation using a random-effect model or fixed-effect model according to interstudy heterogeneity. RESULTS There were totally 14 independent case-control studies of 2810 patients and 3080 healthy controls included. Significant associations were found between KCNE1 G38S polymorphism and AF in overall population under all genetic models: allelic (OR: 1.34, 95% CI: 1.24-1.45, P < .001), homozygous (OR: 1.90, 95% CI: 1.61-2.24, P < .001), heterozygous (OR: 1.43, 95% CI: 1.21-1.68, P < .001), recessive (OR: 1.42, 95% CI: 1.20-1.69, P < .001), dominant genetic model (OR: 1.62, 95% CI: 1.39-1.89, P < .001). Subgroup analyses indicated similar association in Chinese and white. CONCLUSIONS The G38S polymorphism in the KCNE1 gene can significantly increase the risk of AF in both Chinese and white.
