Abstract
BACKGROUND Endoscopic mucosal resection (EMR) appears to be a promising technique for the removal of sessile serrated polyps (SSPs) ≥ 10 mm. To assess the effectiveness and safety of EMR for removing SSPs ≥ 10 mm, we conducted this systematic review and meta-analysis. METHODS We conducted a thorough search of Embase, PubMed, Cochrane, and Web of Science databases for relevant studies reporting on EMR of SSPs ≥ 10 mm, up until December 2023. Our primary endpoints of interest were rates of technical success, residual SSPs, and adverse events (AE). RESULTS Our search identified 426 articles, of which 14 studies with 2262 SSPs were included for analysis. The rates of technical success, AEs, and residual SSPs were 100%, 2.0%, and 3.1%, respectively. Subgroup analysis showed that the technical success rates were the same for polyps 10-19 and 20 mm, and en-bloc and piecemeal resection. Residual SSPs rates were similar in en-bloc and piecemeal resection, but much lower in cold EMR (1.0% vs. 4.2%, P = 0.034). AEs rates were reduced in cold EMR compared to hot EMR (0% vs. 2.9%, P = 0.168), in polyps 10-19 mm compared to 20 mm (0% vs. 4.1%, P = 0.255), and in piecemeal resection compared to en-bloc (0% vs. 0.7%, P = 0.169). CONCLUSIONS EMR is an effective and safe technique for removing SSPs ≥ 10 mm. The therapeutic effect of cold EMR is superior to that of hot EMR, with a lower incidence of adverse effects.

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
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
Purpose We aimed to explore the clinical diagnostic value of combined detection via protein induced by vitamin K absence or antagonist II (PIVKA-II), alpha-fetoprotein (AFP), and D-dimer (D-D) in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). Materials and Methods We analyzed PIVKA-II, AFP, and D-D levels in 291 subjects comprising liver cirrhosis (LC) patients (n = 143) and HCC patients (n = 148). Receiver operating characteristic (ROC) curves were used to analyze and compare the clinical diagnostic value of the three biomarkers for HBV-related HCC alone and in combination. Results The levels of PIVKA-II, AFP, and D-D were positively correlated with tumor size in HCC patients. The levels of PIVKA-II and AFP in early-stage HCC, advanced HCC, HBV DNA+ HCC, and HBV DNA- HCC patients were higher than those in LC patients, while the levels of D-D were lower. The area under the curve for combined detection was greater than that for single-index detection in early-stage HCC, advanced HCC, HBV DNA+ HCC, and HBV DNA- HCC patients. Conclusion D-D may be a useful biomarker for the diagnosis of HBV-related HCC. The combined detection of PIVKA-II, AFP, and D-D had better diagnostic value for different types of HCC than the detection of individual biomarkers.

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 determine the role of replication factor C subunit 5 (RFC5) in acute myeloid leukemia (AML) from four aspects: expression, prognosis, biological functions, and its effects on the immune system. METHODS The RFC5 gene expression and survival analyses, biological function analyses including functional enrichment analysis of genes co-expressed with RFC5, RFC5-interacted gene network construction, gene set enrichment analysis (GSEA), and immune infiltration analysis were performed using data based on GDC TCGA and GEO. The CIBERSORT algorithm was employed to quantify immune cell fractions. All the statistical analyses were performed in SPSS software, GraphPad Prism, and R software. RESULTS RFC5 expression was abnormally expressed in AML (P <0.05). Notably, differential RFC5 expression was observed among different FAB AML subtypes and hematopoietic lineages (all P <0.05). More importantly, high RFC5 expression served as an independent prognostic factor for the poor overall survival of AML patients (P <0.001). Enrichment analyses revealed that RFC5 was involved in cell cycle-related pathways in AML. CIBERSORT analysis showed high proportions of M2 macrophages in the high RFC5 expression group. CONCLUSIONS RFC5 might serve as an effective and robust biomarker for the diagnosis and prognosis of AML. RFC5 might be involved in the AML progression via cell cycle regulation. Moreover, the correlation between RFC5 and immune cells might provide potential assistance for AML treatment.

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
Purpose We explored the expression levels of IgG4 and interleukin (IL)-21 in the serum and ankle joints of collagen-induced arthritis (CIA) rats at different disease stages. Materials and Methods Wistar rats were randomly divided into normal and model groups, and the latter group was administered bovine type II collagen to induce arthritis. Enzyme-linked immunosorbent assay was performed at 21, 28, 35, and 42 days to detect IgG4 and IL-21 in the serum, followed by histological and immunohistochemical analyses of IgG4 and IL-21r in the ankle joint of rats. Results The contents of IgG4 and IL-21 in the serum of the CIA model group were positively correlated and increased with disease progression. The expression of IgG4 and IL-21 receptors in the ankle joint of the CIA model group was significantly higher than that in the control group. These proteins were closely related to the pathological score. The serum IL-21 level in the model group was closely related to the level of IL-21 receptor in the ankle joint. Conclusion IL-21 may promote the occurrence and development of rheumatoid arthritis by combining with IL-21r to regulate the content of IgG4.

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
Purpose Spermidine (SPD) is a naturally occurring polyamine. In this study, we examined the role and possible mechanism of SPD in collagen-induced arthritis (CIA) mice. Materials and Methods CIA mice were intraperitoneally injected with SPD (2 and 50 mg/kg), dexamethasone (0.5 mg/kg), or saline daily for 21 days. The severity of the disease and inflammatory responses in the serum and joint tissue were assessed through macroscopic, immunohistochemical, and histological analyses. Results Macroscopic and histological results indicated that SPD protected against the development of CIA. SPD suppressed the levels of the pro-inflammatory cytokines IL-6 and IL-1β and increased the levels of the anti-inflammatory factor IL-10 in the serum. Immunohistochemical staining showed that 50 mg/kg SPD inhibited iNOS expression in synovial macrophages in the ankle joints of CIA mice. Conclusion These results suggest that SPD may protect CIA mice by inhibiting the polarization of M1 macrophages in the synovial tissue, reducing pro-inflammatory cytokines, and promoting anti-inflammatory factor release.

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
BACKGROUND AND AIM Fully covered self-expandable metal stents (FCSEMSs) have been increasingly used in the management of benign or malignant biliary disorders. However, the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) with transpapillary placement of the FCSEMS remains controversial. This study therefore aimed to investigate the risk of PEP in patients who received FCSEMS implantation. METHODS In total, 602 patients who underwent endoscopic transpapillary FCSEMS placement at five Chinese medical centers, between 2011 and 2018, were included in this retrospective study. Patients who were younger than 18 years and with stent placement above the papilla were excluded from the study. PEP and the risk factors were reviewed. RESULTS PEP occurred in 56 (9.3%) patients, and eight (1.3%) of them experienced moderate-to-severe PEP. The incidence of PEP rose to 14.6% (51/349) when patients had no pancreatic duct (PD) dilation, and even to 18.6% if no prophylactic approaches were adopted. Prophylactic PD stenting showed better efficacy in reducing the incidence of PEP than did rectal use of indomethacin (3.5% vs 10.8%, P = 0.023). Multivariate logistic regression revealed that difficult cannulation (OR 2.837, 95% CI 1.245-6.465, P = 0.013), PD dilation (OR 0.145, 95% CI 0.05-0.422, P < 0.001), and PD stenting (OR 0.247, 95% CI 0.089-0.686, P = 0.007) were significantly associated with PEP risk. Post-procedure cholecystitis was found in 4.0% of patients. CONCLUSION The risk of post-procedure pancreatitis is modestly increased in patients receiving transpapillary FCSEMS placement, particularly when there is absence of PD dilation. Thus, prophylactic pancreatic stenting is recommended in such a condition.

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
This study uses a combined data envelopment analysis and logarithmic mean Divisia index (DEA-LMDI) method to decompose affecting factors for PM2.5 emissions into effects related to the potential emission intensity (PEI), environmental efficiency and technology, production efficiency and technology, regional economic structure, and national economic growth, and investigates differences in the effects on PM2.5 emissions, considering the diversity among different areas and periods in China. This study provides a new insight in the decomposition method, which can decompose the emissions into new effects compared with the exiting studies. This study reveals that the regional environmental-based technology (EBT) effect is the key curbing factor for PM2.5 emissions, followed by the regional PEI effect. The curbing effect of regional EBT on PM2.5 emissions is strong in East China and weak in Northeast China. The environment-oriented scale efficiency (ESE), environment-oriented management efficiency (EME), production-oriented scale efficiency (PSE), production-oriented management efficiency (PME), and production-based technology (PBT) had relatively small effects on PM2.5 emissions on the whole. The effects differ among different areas and periods in China. The emission reduction potential of these efficiency effects has not been realized. The national economic growth greatly promotes PM2.5 emissions. The regional economic structure effect slightly increases PM2.5 emissions because of the unbalanced development of regional economy. The relative policy suggestions are put forward based on the findings of this study.

Abstract
Present investigation was aimed at developing methotrexate (MTX) and miR-22 mimics-loaded lipid nanoparticles for the effective treatment of rheumatoid arthritis. The dual therapeutics loaded nanoparticles was prepared and subjected to in vitro and in vivo characterizations. The in vivo study was performed on adjuvant- induced arthritis model. The addition of IL-1β significantly decreased the expression of miR-22 levels in negative control groups, whereas miR-22 mimics treated cells showed significantly higher miR-22 expression compared to both the NC groups. MTX+miR-22 showed significantly lower cell viability compared to that of free MTX indicating a synergistic anti-inflammatory in the MH7A cells. To be specific, MTX/miR-22-loaded lipid nanoparticles (MTmiR-NP) showed the significantly lower cell viability compared to any other group indicating the potential of lipid nanoparticles. Consistently, MTmiR-NP exhibited a significantly higher cell apoptosis (~50%) compared to any other tested group further reiterating the nanoparticle-based combinational therapeutics. MTmiR-NP exhibited the significant reduction in the paw thickness and significantly lower arthritic score compared to all other groups on all time points. Present study clearly highlights the potential of lipid nanoparticles-based synergistic combination of MTX and miR-22 in achieving higher therapeutic response in rheumatoid arthritis treatment.

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
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
In this study, a simple and effective strategy for the enrichment of total steroidal saponins (TSS) from the fibrous roots of Ophiopogon japonicus (L. f.) Ker-Gawl. (FROJ) using macroporous adsorption resin was systematically developed. XAD-7HP resin was selected from six macroporous resins for further study because of the highest static adsorption and desorption capacities. The static adsorption of TSS on XAD-7HP resin fitted well to the Langmuir isotherm model and pseudo second-order kinetic model; the thermodynamics test showed that the adsorption process was spontaneous and exothermic. The dynamic tests on XAD-7HP resin columns demonstrated that the breakthrough volume was 16 bed volume (BV), and 6 BV of 80% ethanol was suitable for dynamic desorption. In a lab scale-up separation under optimal dynamic conditions, the content of TSS in the resin-enrichment fraction increased from 1.83% in the crude extracts to 13.86% by 7.59-fold with a recovery yield of 82.68%. Three steroidal saponins were obtained from the resin-enrichment fraction, and showed protective effects against oxidized low-density lipoprotein (ox-LDL) induced human umbilical vein endothelial cell (HUVEC) injury. Overall, these results suggested that XAD-7HP resin chromatography was an effective strategy for the large scale enrichment of TSS from FROJ, which showed the potential for functional food and pharmaceutical application. In this study, a simple and effective strategy for the enrichment of total steroidal saponins (TSS) from the fibrous roots of Ophiopogon japonicus (L. f.) Ker-Gawl. (FROJ) using macroporous adsorption resin was systematically developed.![]()

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
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
A 2-period field trial was conducted to determine the effects of feeding regimen on weight gain, semen characteristics, libido, and lameness in 170- to 200-kg (period 1) and 200- to 250-kg (period 2) boars. Sixty-one Duroc boars were allotted to 1 of 3 dietary treatments and 15 g/d fish oil was also provided for each experimental boar, to maintain the n-6:n-3 intake ratio at approximately 6.1:1. The energy intakes of the 3 treatment groups were controlled by basing the feed intake on a corn-soybean meal-based diet (3.11 Mcal/kg of ME) to create: 1) low energy intake group (L, = 20, 7.3 Mcal/d of ME), 2) medium energy intake group (M, = 20, 7.7 Mcal/d of ME), and 3) high energy intake group (H, = 21, 8.3 Mcal/d of ME) in period 1. Feed intake was then increased to 7.6, 8.2, and 8.6 Mcal/d of ME for the 3 groups, respectively, in period 2. During the 28-wk experimental period, boar weight gain, testis volume, semen characteristics, libido, toe measurements, claw lesions, and lameness were examined, and the number of boars culled in each group was recorded to calculate the culling rate. Although there were no differences in testis volume, sperm concentration, and motility, the percentage of abnormal sperm, the percentage of claw lesions, and claw lesion scores differed among treatments ( > 0.05), and ADG was significantly increased with the increase of energy intake between the 2 periods ( < 0.05). The M and H boars had significantly greater total sperm number and functional sperm number than the L boars ( < 0.05), while no significant difference was observed between the M and H groups ( > 0.05). Nonetheless, the H boars took more time to mount the collection dummy and produce an ejaculate and, in particular, showed a greater percentage of lameness than the L and M boars ( < 0.05). Therefore, the medium energy intake regimen (energy intakes of 7.7 and 8.2 Mcal/d of ME with ADG of 454.5 and 375.3 g/d in 2 periods, respectively) improved the total sperm number and functional sperm number, and meanwhile decreased the occurrence of lameness in 170- to 250-kg Duroc boars.

Abstract
The aim of the current study was to determine the digestible lysine (DLys) requirement of Cherry Valley ducks from 1 to 14 d and from 15 to 35 d of age. One-day-old male Cherry Valley ducks (n = 320) were divided randomly and evenly into five treatments with 8 replicates of 8 birds. Ducks were fed adequate levels of digestible amino acid but with graded levels of DLys: 0.80, 0.88, 0.96, 1.04, and 1.12% from 1 to 14 d; 0.60, 0.68, 0.76, 0.84, and 0.92% from 15 to 35 d. At 35 d of age, 8 ducks per treatment were slaughtered for evaluating the yields of abdominal fat, subcutaneous fat, breast meat, and leg meat. Additionally, a 7-d metabolizable experiment was conducted with ducks of the same hatch beginning on d 35 (8 ducks per treatment). The results showed that the DLys level in diet had a quadratic relationship both with the average daily gain (ADG) and feed:gain ratio (F/G). According to the quadratic model, an optimum digestible lysine level was 0.948% from 0 to 14 d and 0.758% from 15 to 35 d based on ADG. The digestible lysine level for obtaining minimum F/G were 0.986% (0 ∼ 14 d) and 0.792% (15 ∼ 35 d), respectively. Breast meat yield (P = 0.110) and subcutaneous fat percentage (P = 0.021) showed a quadratic or linear response to the increasing dietary DLys level. To achieve maximum breast meat yield, the digestible lysine level of 0.961% and 0.761% were needed for the starter period (1 ∼ 14 d) and the growth period (14 ∼ 35 d), respectively. N excretion showed a quadratic response to the increasing dietary DLys level (P = 0.103). The results of the current study suggested that the optimum digestible lysine level was very different with the response criterion. The dietary digestible lysine levels were 0.948, 0.961% in the starter period (1 ∼ 14 d) and 0.758, 0.761% in the growth period (15 ∼ 35 d) for ADG, F/G, respectively.

Abstract
Coilia ectenes is a commercially important fishery species in China. C. ectenes taihuensis is an endemic and dominant species found in Taihu Lake of China. When compared with C. ectenes, C. ectenes taihuensis lacks anadromous behavior, and can independently grow and reproduce in Taihu Lake. In this study, the mitochondrial DNA control region (D-loop) sequences were employed to investigate the genetic diversity and population structure of C. ectenes taihuensis. Sixty-eight individuals collected from 4 localities in Taihu Lake were examined. Results indicated that in the 887-bp D-loop region, seventy-seven (8.68%) sites were variant, contributing to 53 distinct haplotypes. Although the population haplotype diversity (Hd = 0.971 to 1.000) was generally high, the nucleotide diversity (π = 0.616 to 0.731%) was relatively low among the 4 populations. Additionally, the genetic distances ranged from 0.62 to 0.74% within the populations and from 0.67 to 0.74% between the populations. The neighbor-joining tree indicated that a distinct distribution of phylogenetic structure existed among haplotypes. Analysis of molecular variance and FST statistics suggested that a divergence existed among populations in 4 localities, indicating that gene communication might have occurred among those populations. Furthermore, neutral tests and analysis of mismatch distribution reflected that C. ectenes taihuensis might have undergone a population expansion during the evolution process. Our study showed the population genetic diversity and structure of C. ectenes taihuensis. Results from this study might be helpful in the development and protection of fishery resource within the localities in Taihu Lake in future.

Abstract
Diagnostic method of Schistosoma japonicum (S.japonicum) is the key of schistosomiasis prevention and control. In China, schistosomiasis reached the stage of transmission control, and almost of the epidemic areas tend to have low infection rate and intensity, but it is difficult for the existing detection methods to achieve accurate monitoring. In this study, a novel method to detect the circulating antigens of S.japonicum using gold nanorods optical sensor was developed. Gold nanorods were prepared by seed-mediated growth followed by deposition onto Indium-Tin-Oxide (ITO) glass to fabricate a solid phase biosensor. In order to assembly between the ITO glass and gold nanorod, hydroxylation and sulfhydrylation were carried out to modify the ITO glass. Surface of gold nanorods was conjugated with an SIEA26-28kDaSjscFv antibody against S.japonicum circulating antigens, and the sensor optical changed upon antigen-antibody recognition. The sensor was used to detect S.japonicum infection in rabbits by testing the serum once a week for 8 weeks. Results revealed different displacement of localized surface plasmon resonance (LSPR) of the gold nanorod optical sensor each week while the control group showed no such change in LSPR. Simultaneously, Indirect Hemagglutination Assay(IHA) and Fast Enzyme-Linked Immuno Sorbent Assay (F-ELISA) method were used to test these samples. Ten human serum samples from S.japonicum infected patients were analyzed using the gold nanorods optical sensor, which revealed that health human serum did not show any spectrum displacement. We developed a specificity gold nanorod optical sensor by combining the SIEA26-28kDaSjscFv, which was used to detect circulating antigens of S.japonicum. This method is expected to overcome the issues pertaining to the testing of circulating antigens of S.japonicum.

Abstract
BACKGROUND The conventional venous access for cardiovascular implantable electronic device (CIED) is the subclavian vein, which is often accompanied by high complication rate. The aim of this study was to assess the efficacy and safety of optimized axillary vein technique. METHODS A total of 247 patients undergoing CIED implantation were included and assigned to the axillary vein group or the subclavian vein group randomly. Success rate of puncture and complications in the perioperative period and follow-ups were recorded. RESULTS The overall success rate (95.7% vs. 96.0%) and one-time success rate (68.4% vs. 66.1%) of punctures were similar between the two groups. In the subclavian vein group, pneumothorax occurred in three patients. The subclavian gaps of three patients were too tight to allow operation of the electrode lead. In contrast, there were no puncture-associated complications in the axillary vein group. In the patient follow-ups, two patients in the subclavian vein group had subclavian crush syndrome and both of them received lead replacement. The incidence of complications during the perioperative period and follow-ups of the axillary vein group and the subclavian vein group was 1.6% (2/125) and 8.2% (10/122), respectively (χ2 = 5.813, P = 0.016). CONCLUSION Optimized axillary vein technique may be superior to the conventional subclavian vein technique for CIED lead placement.

Abstract
Previous research has shown benefits of dietary fish oil supplementation on semen quality of boars. However, little is known about how antioxidant protects lipid peroxidation on spermatozoa from n-3 polyunsaturated fatty acid (PUFA) addition. This study evaluated the effect of oregano essential oil (OEO) supplementation on semen antioxidant status and semen quality in boars fed a diet enriched with fish oil. Thirty-four mature boars of proven fertility, received daily 2.5 kg basal diet top-dressed with 45 g soybean oil and 15 g fish oil to meet the n-3 PUFA requirement of spermatozoa, randomly allocated to one of four groups supplemented with 100 mg α-tocopheryl acetate kg-1 (control), or 250 or 500 or 750 mg OEO kg-1 for 16 weeks. Semen was collected at weeks 0, 8, 12 and 16 for measurements of sperm production, motion characteristics, sperm α-tocopherol content, antioxidant enzyme activities, reactive oxygen species (ROS), DNA damage (8-hydroxydeoxyguanosine, 8-OHdG), lipoperoxidation (malondialdehyde, MDA) and seminal total antioxidant capacity (TAC). Sperm production and motion characteristics were similar (p > .05) among groups throughout the experimental week 16, but increased (p < .01) with experimental week. Although higher α-tocopherol content and superoxide dismutase (SOD) activities were in OEO group spermatozoa, feeding diet with 500 mg/kg OEO resulted in elevation in seminal TAC, decrease in sperm ROS, MDA and 8-OHdG than control group (p < .05). Overall, these results support the view that oregano essential oil has a positive effect on antioxidant capacity in boar when used fish oil.

Abstract
OBJECTIVE To study the clinical outcome of autologous ipsilateral lamellar corneal-flap transposition for treatment of peripheral corneal perforation. METHODS Medical records of 13 patients who underwent autologous ipsilateral lamellar corneal-flap transposition for peripheral corneal perforation from January 2008 to February 2015 were retrospectively reviewed. The diameter of the corneal ulcers was all ≤ 3.0 mm, and the diameter of perforations was all ≤ 2.0 mm. All patients were followed up for 3-12 months with an average of 8 months. The healing of ulcer, clarity of the grafts, pre-and postoperative visual acuity, and astigmatism were documented and analyzed. RESULTS At 1 day after surgery, all patients had normal anterior chamber depth without aqueous leak. No double chamber or iris synechia was found. The corneal grafts showed mild to moderate edema. On postoperative days 7-14, the corneal edema receded, the grafts became transparent gradually, and the ulcer margin was blurred. Three months after surgery, all the grafts remained transparent. There was no recurrence of ulcer during the follow-up period. The best corrected visual acuity before and after surgery was 0.44 ± 0.19 and 0.47 ± 0.20, respectively, which indicated no statistically significant difference(t=0.706, P=0.461). The corneal astigmatism before and after surgery was 0.44±0.19 and 0.47±0.20, respectively, which showed statistically significant difference(t=2.391, P<0.05). CONCLUSIONS Autologous ipsilateral lamellar corneal-flap transposition is a safe and effective surgical procedure for treating peripheral corneal perforation. It can be considered as an alternative method for penetrating or lamellar keratoplaty when the availability of corneal tissue is limited, or for cases with a high risk of developing immunologic allograft rejection, although the surgical indications are limited.

Abstract
BACKGROUND Bevacizumab, a recombinant humanized monoclonal antibody that blocks angiogenesis by inhibiting vascular endothelial growth factor A, was described to be effective in the treatment of recurrent or platinum-resistance ovarian cancer. The present retrospective study was performed to further evaluate the clinical efficacy and toxicity of bevacizumab in the treatment of Chinese recurrent ovarian cancer patients who had been previously treated by platinum-based chemotherapy. MATERIALS AND METHODS We reviewed the hospital database and finally included 26 recurrent ovarian cancer patients who were treated with bevacizumab combined with gemcibabine or paclitaxel or single agent. All included patients received >3 cycle of bevacizumab treatment. The tumor response, overall survival, and toxicities were documented. RESULTS Under the treatment of bevacizumab combined with gemcibabine or paclitaxel, 2 complete response (7.7%), 8 partial response (30.8%), 7 stable disease (26.9%) and 9 progression disease (34.6%) was documented with the objective response rate of 38.5% and disease control rate of 65.4%. The median overall survival from the first application of bevacizumab was 15.3 months [Figure 1] for all of the 26 patients. The median overall survival time was 16.2 and 14.0 months for bevacizumab + gemcitabine and bevacizumab + paclitaxel treatment schedule respectively. The overall survival was not different between bevacizumab + gemcitabine and bevacizumab + paclitaxel treatment regimen hazard ratio = 0.80 (95% confidence interval: 0.32-2, P = 0.64). The hypertension and proteinuria were the major bevacizumab related toxicities. CONCLUSIONS Bevacizumab combined with gemcibabine or paclitaxel was a promising treatment schedule for platinum-resistance recurrent ovarian cancer.

Abstract
Paroxysmal kinesigenic dyskinesia is a rare episodic movement disorder that can be isolated or associated with benign infantile seizures as part of choreoathetosis syndrome. Mutations in the PRRT2 gene have been recently identified as a cause of paroxysmal kinesigenic dyskinesia and infantile convulsion and choreoathetosis (ICCA). We reported a PRRT2 heterozygous mutation (c.604-607delTCAC, p.S202Hfs*25) in a 3-generation Chinese family with infantile convulsion and choreoathetosis and paroxysmal kinesigenic dyskinesia. The mutation was present in 5 family members, of which 4 were clinically affected and 1 was an obligate carrier with reduced penetrance of PRRT2. The affected carriers of this mutation presented with a similar type of infantile convulsion during early childhood and developed additional paroxysmal kinesigenic dyskinesia symptoms later in life. In addition, they all had a dramatic clinical response to oxcarbazepine/phenytoin therapy. Reduced penetrance of the PRRT2 mutation in this family could warrant genetic counseling.

Abstract
The pharmacokinetics and bioavailability of cefquinome in Beagle dogs were determined by intravenous (IV), intramuscular (IM) or subcutaneous (SC) injection at a single dose of 2 mg/kg body weight (BW). The minimum inhibitory concentrations (MIC) of cefquinome against 217 Escherichia coli isolated from dogs were also investigated. After IV injection, the plasma concentration-time curve of cefquinome was analyzed using a two-compartmental model, and the mean values of t1/2α (h), t1/2β (h), Vss (L/kg), ClB (L/kg/h) and AUC (μg·h/mL) were 0.12, 0.98, 0.30, 0.24 and 8.51, respectively. After IM and SC administration, the PK data were best described by a one-compartmental model with first-order absorption. The mean values of t1/2Kel , t1/2Ka , tmax (h), Cmax (μg/mL) and AUC (μg·h/mL) were corresponding 0.85, 0.14, 0.43, 4.83 and 8.24 for IM administration, 0.99, 0.29, 0.72, 3.88 and 9.13 for SC injection. The duration of time that drug levels exceed the MIC (%T > MIC) were calculated using the determined MIC90 (0.125 μg/mL) and the PK data obtained in this study. The results indicated that the dosage regimen of cefquinome at 2 mg/kg BW with 12-h intervals could achieve %T > MIC above 50% that generally produced a satisfactory bactericidal effect against E. coli isolated from dogs in this study.

Abstract
AIM: To determine the existence of a potential relationship between the methylation state of the Vimentin gene and its prognostic value in pancreatic cancer.
METHODS: Sixty-four primary tumor specimens and normal tissues were collected consecutively from pancreatic cancer patients during surgery at Hangzhou First People’s Hospital and Affiliated Hospital of the Logistics University of the Chinese People’s Armed Police Force. DNA was extracted from the samples and subsequently quantitative methylation-specific polymerase chain reaction was used to detect the Vimentin methylation status of the samples. All of the patients were followed up to December 2012. χ2 test, Kaplan-Meier survival and Cox regression statistical models were used.
RESULTS: Out of 64 pancreatic cancer tissues, 21 were marked as Vimentin methylation-positive, and 43 were marked as Vimentin methylation-negative. The location of pancreatic carcinoma was related to the Vimentin methylation state. The pathological T staging (P < 0.001), adjuvant chemotherapy (P = 0.003) and the Vimentin methylation state (P = 0.037) were independent prognostic factors.
CONCLUSION: In our study, Vimentin methylation status can predict the prognosis of pancreatic cancer patients. However, additional experiments and clinical trials are needed to accurately validate this observation.
