Abstract
While there have been previous studies examining the relation between the rs17820943 and rs6072081 polymorphisms in the v-maf musculoaponeurotic fibrosarcoma oncogene homolog B (MAFB) gene and rates of nonsyndromic cleft lip with or without cleft palate (NSCL/P), at present the results of these studies have been inconsistent. This meta-analysis therefore aimed to conduct a more robust assessment of the association between the MAFB rs17820943 and rs6072081 polymorphisms and NSCL/P risk. The Embase, Web of Science, PubMed, the China National Knowledge Internet (CNKI), and Wanfang databases were systematically searched to identify relevant studies. In total, five studies incorporating 2769 patients and 2885 controls were identified assessing the rs17820943 polymorphism and three studies incorporating 1242 patients and 1310 controls assessing the rs6072081 polymorphism were identified. This analysis revealed the MAFB rs17820943 and rs6072081 polymorphisms to be linked to a significantly reduced NSCL/P risk (rs17820943: C vs T: OR=0.76, 95% CI=0.70-0.82; CC vs CT: OR=0.75, 95% CI=0.67-0.85; CC vs TT: OR=0.58, 95% CI=0.49-0.67; CC+CT vs TT: OR=0.67, 95% CI=0.59-0.77; CT+TT vs CC: OR=1.43, 95% CI=1.28-1.60; rs6072081: A vs G: OR=0.77, 95%CI=0.68-0.86; AA vs AG: OR=0.76, 95%CI=0.64-0.90; AA vs GG: OR=0.58, 95%CI=0.45-0.74; AA+AG vs GG: OR=0.68, 95%CI=0.54-0.84; AG+GG vs AA: OR=1.40, 95% CI=1.19-1.65). The results of the present meta-analysis indicate that in an East Asian population, for both rs17820943 and rs6072081 were associated with NSCL/P.

Abstract
Objective: To explor staging of the general course of occupational medicamentosa-like dermatitis due to trichloroethylene (OMDT) to better understand the characteristics of OMDT course, and to provide reference for clinical diagnosis and treatment and related studies. Methods: We collected main clinical manifestation and auxiliary examination data during hospitalization to May 2019 from 35 OMDT patients with complete course record who were hospitalized from January 2014 to December 2018. Continuous monitoring indicators with changing trends including main clinical manifestation indicators, peripheral white blood cell counts, liver function indicators such as serum alanine aminotransferase activity, myocardial enzyme indicators such as serum lactate dehydrogenase activity were selected and used with their standardized values to do cluster analysis on time point (week as unit) of the course of each patient. The clustering results combined with changing trends of the indicators were used to determine the stages of course of each patient, and therefore the staging of general course of OMDT was calculated. Positive rates or average levels of the indicators were compared between different stages, and the correlation of duration of each stage was analyzed with physical characteristics, disease characteristics and treatment measures of the patients. Results: General course of OMDT could be divided into acute phase (3.0±1.5) weeks and chronic phase (11.0±4.4) weeks, while chronic phase could be further divided into early period (5.0±3.0) weeks and later period (6.5±3.7) weeks. Compared with chronic phase, clinical manifestation indicators, white blood cell counts (except eosinophil count) , liver function indicators (except total protein and albumin concentration) , and myocardial enzyme indicators were all increased (all P<0.01) , while total protein and albumin concentration decreased (P<0.05 and P<0.01, respectively) in acute phase. Compared with later period of the chronic phase, clinical manifestation indicators (except fever) , white blood cell counts (except lymphocyte count) , liver function indicators (except total protein and albumin concentration) , and creatine kinase isoenzyme activity were all increased (all P<0.01) , while total protein, albumin concentration and creatine kinase activity decreased (all P<0.01) . Duration of acute phase were positively correlated with the time before glucocorticoid treatment (r(spearman)=0.62, P(adjust)<0.01) , and early and later periods of chronic phase were both positively correlated with corresponding duration of glucocorticoid treatment (r(spearman)=0.96, P(adjust)<0.01, r(spearman)=0.91, P(adjust)<0.01, respectively) . Conclusion: For the first time, the study objectively determined stages of general course of OMDT based on combination of multiple indicators, and analyzed characteristics of main indicators in each phase and potential factors related to the duration of each phase.

Abstract
The submental artery perforator flap (SAPF) has been a new option for the intraoral reconstruction of oral squamous cell carcinoma (OSCC) patients in recent years, but its surgical outcomes have not been well assessed. We compared the surgical outcomes and oncological safety of SAPF reconstruction for medium-sized soft-tissue defects after the ablation of primary oral cancer with traditional submental island flaps (SIF) and anterolateral thigh perforator flaps (ALTPF). Fifty-one SAPFs, 30 SIF, and 74 ALTPF were reviewed for the intraoral medium-sized reconstructions after the ablation of oral cancer from our institutional clinical oncological databases. We performed comparative assessments on the variables of surgical outcome and oncological safety among the 3 cohorts. A Kaplan-Meier estimate of survival for each flap was calculated. Operating time was significantly reduced in the SIF and SAPF groups than ALTPF (p = 0.021 and 0.014, respectively). Flap thickness of SAPF was the significantly thinnest (mean 0.5 cm) among three groups. The common complications of donor site for both SAPF and SIF group were incision dehiscence and orocutaneous fistula. There was no significant difference in disease-free survival (DFS) among the 3 groups. However, several OSCC patients with the SIF reconstruction were found to have recurrences with a metastatic lymph node under the flap after the first operation. SAPF could be a versatile choice of the intraoral reconstruction for the medium-sized soft-tissue defects after the ablation of oral cancer.

Abstract
OBJECTIVES The relationship between marijuana use and markers of chronic lung disease in people living with HIV (PLWH) is poorly understood. METHODS We performed a cross-sectional analysis of the Examinations of HIV-Associated Lung Emphysema (EXHALE) study, including 162 HIV-positive patients and 138 participants without HIV. We modelled marijuana exposure as: (i) current daily or weekly marijuana smoking vs. monthly or less often; or (ii) cumulative marijuana smoking (joint-years). Linear and logistic regression estimated associations between marijuana exposure and markers of lung disease, adjusted for tobacco smoking and other factors. RESULTS In PLWH, current daily or weekly marijuana use was associated with a larger forced vital capacity (FVC), larger total lung capacity and increased odds of radiographic emphysema compared with marijuana non-smokers in adjusted models; these associations were not statistically significant in participants without HIV. Marijuana joint-years were associated with higher forced expiratory volume in 1 s and FVC in PLWH but not with emphysema. CONCLUSIONS In PLWH, marijuana smoking was associated with higher lung volumes and potentially with radiographic emphysema. No consistently negative associations were observed between marijuana and measures of chronic lung health.

Abstract
Objective: To explore the the effectiveness of using short-latency somatosensory evoked potential(SLSEP) combined with electroencephalogram(EEG) reactivity to predict the prognosis of severe brain injury(SBI) patients. Methods: Consecutive patients with SBI admitted in neurosurgery intensive care unit(NSICU) at Xiangya Hospital of Central South University from July 2018 to January 2019 were prospectively collected. SLSEP and EEG were recorded in these patients in NSICU within two weeks after injury onset. EEG reactivity(EEG-R) was tested during EEG signal stabilization. In addition, the concentrations of serum neuron-specific enolase (NSE) and S100 protein were also detected. All patients were evaluated with Glasgow Outcome Scale(GOS) during 12 months' follow-up. GOS grade 3 to 5 was defined as favorable group, and GOS grade 1 to 2 was defined as unfavorable group. The association of relevant predictors with patient's prognosis was assessed. The area under the receiver operating characteristic (ROC) curve (AUC) was used to evaluate each potential predictor. Results: Forty-three patients were included in the study, with 26 patients of favorable outcomes and 17 patients with unfavorable prognosis. Univariate analysis revealed that the Glasgow Coma Scale (GCS) score, the concentration of serum NSE, EEG-R, the amplitude of SLSEP were all associated with the prognosis after 12 months' follow-up. Moreover, the AUC for prediction of favorable prognosis by GCS, NSE, EEG-R, SLSEP was 0.661(95%CI: 0.493-0.829), 0.697(95%CI: 0.531-0.862), 0.718(95%CI: 0.557-0.879) and 0.758(95%CI: 0.609-0.907) respectively. However, there was no significant difference of age, gender, pupillary light reflex and S100 protein between the two groups. Furthermore, multiple logistic regression analysis showed that only SLSEP amplitude (OR=2.058, 95%CI: 0.867-4.888) and EEG-R(OR=3.748, 95%CI: 0.857-16.394) were independent predictors of favorable prognosis, and the prognostic model containing these two variables yielded an predictive performance with an AUC of 0.798. Conclusion: The higher amplitude of SLSEP and the existence of EEG-R are predictors of good prognosis in SBI patients, and the combined use of SLSEP and EEG-R in predicting the prognosis of SBI patients is more reliable.

Abstract
Mineral nutrition plays a critical role in growth and bone mineralization in meat ducks as well as reproductive performance in duck layers and duck breeders. In addition to improving production performance parameters, minerals are also essential to support several enzymatic systems to enhancing antioxidant ability and immune function. This review explores the biological function and metabolism of minerals in the body, as well as mineral feeding strategy of various species of ducks. Topics range from mineral requirement to the physiological role of macroelements such as calcium and phosphorus and microelements such as zinc and selenium, etc. As with the improvement of genetic evolution and upgrade of rearing system in duck production, mineral requirements and electrolyte balance are urgent to be re-evaluated using sensitive biomarkers for the modern duck breed characterized by the rapid growth rate and inadequate bone development and mineralization. For duck breeders, mineral nutrition is not only required for maximal egg production performance but also for maintaining normal embryonic development and offspring's performance. Therefore, the proper amounts of bioavailable minerals need to be supplemented to maintain the mineral nutritional state of duck species during all phases of life. In addition, more positive effects of high doses microelements supplementations have been revealed for modern meat ducks subjected to various stresses in commercial production. The nutritional factors of mineral sources, supplemental enzymes, and antinutritional factors from unconventional ingredients should be emphasized to improve the effectiveness of mineral nutrition in duck feed formulation. Organic mineral sources and phytase enzymes have been adopted to reduce the antagonistic action between mineral and antinutritional factors. Therefore, special and accurate database of mineral requirements should be established for special genotypes of ducks under different rearing conditions, including rearing factors, environmental stresses and diets supplemented with organic sources, phytase and VD3.

Abstract
OBJECTIVES The purpose of this study was to compare the changes of the condylar axis, the anteroposterior condylar position relative to the glenoid fossa, after intraoral vertical ramus osteotomy (IVRO). STUDY DESIGN 21 patients diagnosed as skeletal class III malocclusion underwent IVRO and were followed according to the authors' postoperative management regimen. The three-dimensional positions of the condyles were evaluated by cone-beam computerized tomography (CBCT) at pre-op, post-op, and at follow-up. CBCT images were referenced to assess the condylar axis change and the anteroposterior condylar position in the glenoid fossa. A repeated-measures analysis of variance (P<0.05) also was performed. RESULTS After surgery, both the axial condylar angles and the anteroposterior condylar position were significantly different (P<0.05). The coronal condylar axis rotated outwardly. The anteroposterior condylar position in the glenoid fossa had moved from the concentric to the anterior position. But the condyle changes between post-op and follow-up (P>0.05) were insignificant. CONCLUSIONS With postoperative intermaxillary elastic traction, the condyles changed their positions physiologically for newly established jaw movement after IVRO.

Abstract
Objective: To investigate the association of cadmium exposure with liver function among adults in a non-ferrous metal mining area in Guangxi. Methods: A total of 310 residents aged 18 and above were recruited from 5 heavy metals polluted villages in a non-ferrous metal mining area in Guangxi from 2013 to 2014. The general demographic characteristics, blood cadmium levels and indicators of liver function index [Total bilirubin (TBIL), Glutamic oxaloacetic transaminase (AST), Alanine transaminase (ALT) and Glutamine transaminase (GGT)] were obtained by using questionnaire, physical examination and laboratory test. The blood cadmium levels were divided into quartiles as Q1-Q4 groups (using Q1 group as the reference).Multivariate logistic regression model was used to analyze the correlation between the blood cadmium level and functional liver index. Results: The age of subjects was (49.2±15.4) years, and 112 (36.1%) subjects were male residents. The prevalence of abnormal rates of TBIL,AST,ALT and GGT were 17.4% (54), 19.7% (61), 10.7% (33) and 11.9% (37), respectively. The geometric mean value of cadmium levels in adults was 3.72(95%CI: 3.43-4.02) μg/L. After adjusting for age, gender, body mass index (BMI), smoking, drinking, total cholesterol, hypertriglyceridemia and other factors, the risk of abnormal AST index in the highest concentration of blood cadmium group (Q4) was higher than that in the lowest concentration of blood cadmium group (Q1) (OR=2.92, 95%CI:1.07-7.98). Conclusion: The level of blood cadmium exposure is higher than the reference value of general population in China, and the elevated cadmium exposure is related to the increasing risk of AST abnormality.

Abstract
Macrophages are important members of innate immunity and play an extremely important role in the host defense against pathogenic infections, tumors, and allergic diseases. Macrophages have a high degree of plasticity, and may be polarized into classical activated macrophages (M1 macrophages) and alternative activated macrophages (M2 macrophages) under the stimulation of different environments. M1 macrophages are found to promote inflammatory responses, which facilitates the clearance of pathogens, while M2 macrophages may inhibit inflammatory responses, which facilitates the survival and reproduction of pathogens. This review summarizes the role of macrophage polarization in parasitic infections, so as to provide insights into the prevention and treatment of parasitic diseases.

Abstract
Survival rates for oral squamous cell carcinoma (OSCC) has remained stagnant in recent years and improving surgical mortality could be an avenue to enhance outcomes. This systematic review aims to identify the causes of mortalities, determine both the modifiable and non-modifiable factors involved and target a reduction in postoperative 30-day mortality. In May 2019, a comprehensive search of key databases including PubMed, EMBASE, Cochrane Library was conducted. Blinded selection by two researchers identified papers that included participants who received oral squamous cell carcinoma resection and suffered an in-hospital or 30-day mortality. Selection identified two relevant papers that meet the inclusion criteria. One study had one death in its population sample but only had the cause of death described. Another study had an overall surgical mortality rate of 1% in a population of 21,681. Patients with multiple factors had the highest mortality rates; 4.6% in patients >85 years old and have a T4 diagnosis, 3.9% in patients with a Comorbidity Index ≥1 and a T4 diagnosis. These studies did not determine relationships between factors and causes of death. There are significant knowledge gaps in the literature, that can be addressed through further population analysis studies.

Abstract
OBJECTIVE Long non-coding RNA (lncRNA) is a significant member of the non-coding RNA family. New evidence has shown that it plays a pivotal role in the processes of tumor genesis and development. According to previous verification, the lncRNA Tubulin Alpha 4B (TUBA4B) is a tumor-associated molecule, but how TUBA4B expresses and functions in breast cancer is still not clear. PATIENTS AND METHODS We conducted this study to examine what expression and biological role TUBA4B plays in breast cancer. The expression of TUBA4B was measured in breast cancer samples and cell lines. CCK8 assays and transwell assays were used for evaluating the effects of TUBA4B on breast cancer cell proliferation and invasion. Luciferase reporter assays were used for identifying the direct target of TUBA4B. RESULTS According to the results, TUBA4B was largely downregulated in breast cancer samples and cell lines. The functional analysis demonstrated that breast cancer cells proliferation and invasion could be inhibited by overexpression of TUBA4B. The results of Luciferase reporter assays indicated that TUBA4B directly targeted miR-19, which could rescue the effects of TUBA4B on breast cancer cells. CONCLUSIONS It is suggested that TUBA4B was downregulated in breast cancer and suppressed proliferation and invasion of breast cancer by targeting miR-19.

Abstract
The specific expression profile and function of circular RNAs (circRNAs) in mammalian ovarian follicles, especially during the atresia process, are unclear. In this study, genome-wide deep circRNA sequencing was applied to screen circRNAs in healthy and early atretic antral follicles in pig ovaries. A total of 40,567 distinct circRNAs were identified in follicles, among which 197 circRNAs (108 upregulated and 89 downregulated) were significantly shifted during the early atresia process. Most differentially expressed circRNAs (DECs) lacked protein-coding potential. Annotation analysis of the DECs revealed 162 known host genes, or noncoding RNAs, and 10 intergenic regions. The key pathways in which these host genes are involved include the focal adhesion-PI3K-Akt-mTOR signaling pathway, vascular endothelial growth factor A (VEGFA)-vascular endothelial growth factor receptor 2 signaling pathway and transforming growth factor-beta signaling pathway. Further comparison analysis between host genes of DECs and the differentially expressed linear messenger RNA transcripts revealed the cotranscription of circRNAs and their linear mRNAs in inhibin beta units (INHBA and INHBB), glutathione S-transferase (GSTA1), and VEGFA. In addition, we predicted 196 pairs of potential circRNA-micro RNA (miRNA) interactions among 77 DECs and 101 porcine miRNAs. We have identified 16 functional miRNAs by comparing the 101 miRNAs to the functional miRNAs reported in mammal ovarian follicle atresia and granulosa cell apoptosis studies. Our study adds new knowledge to circRNA distribution profiles in pig ovarian follicles, offers a valuable reference for transcriptomic profiles in the initiation of follicular atresia, highlights warranted circRNAs for further functional investigation, and provides possible biomarkers for ovarian dysfunctions.

Abstract
BACKGROUND Previous studies have demonstrated that pure transanal endoscopic surgery is safe and feasible in the treatment of rectal cancer. However, the role of pure transanal endoscopic colectomy in ascending colon cancer (ACC) treatment has not been evaluated. We report a case of transanal endoscopic surgery for ACC. METHODS A 35-year-old woman was treated for ACC, using a transanal endoscopic surgery device as the operation platform, and pure transanal endoscopic right hemicolectomy without transabdominal assistance was safely performed. An instrument suture, side-to-side, ileocolic anastomosis was performed. Operative time was 245 min and intraoperative blood loss was 60 ml. RESULTS The patient recovered well from the surgery. Compared with the traditional approach, this approach was less invasive and resulted in satisfactory outcomes and cosmesis (no scar). CONCLUSIONS Application of pure transanal endoscopic colectomy without abdominal assistance to ACC appears to be feasible and safe.

Abstract
Objective: To explore the association between serum levels of osteopontin (OPN) and systolic pulmonary artery pressure (sPAP) in healthy men following acute high altitude exposure. Methods: According to the inclusion and exclusion criteria, this observational study included 94 male subjects (aged from 18 to 30 years, dwelling in lowland<500 m) who ascended to Litang (4 100 m) from Chongqing (400 m) by bus with a stair-like journey within 7 days in June 2013. Data including basic information, OPN, superoxide dismutase (SOD), and malondialdehyde (MDA) and echocardiographic derived sPAP were collected within 48 hours before ascent and within 2-7 hours after arrival. Accordingly, subjects were divided into 3 groups based on the tertiles of sPAP after acute high altitude exposure: low sPAP group (26.8-32.3 mmHg (1 mmHg=0.133 kPa)) (n=31), middle sPAP group (32.4-37.4 mmHg) (n=32) and high sPAP group (37.5-55.6 mmHg) (n=31). Associations of serum OPN and SOD levels with sPAP were analysed by univariate and multivariate linear regression analysis. Results: After acute high altitude exposure, the levels of sPAP were significantly increased (P<0.001). There were no differences in age, height, weight, body mass index, percent of Han nationality and smoking among 3 subgroups. However, following acute high altitude exposure, the levels of heart rate, systolic and diastolic blood pressure elevated (all P<0.05), whereas the levels of oxygen saturation were reduced in the total subjects and all subgroups (all P<0.05). Moreover, systolic blood pressure of subjects in the high sPAP group was higher than that in low and middle sPAP groups (both P<0.05), and diastolic blood pressure of subjects in high sPAP group was higher than that in low sPAP group (P<0.05). The serum levels of OPN were increased in total cohort(27.9 (22.5,34.0) μg/L vs. 25.6 (18.4, 33.1) μg/L, P<0.05), and high sPAP group (P<0.05), whereas no differences were found in serum SOD and MDA levels among groups. Furthermore, the serum level of OPN in high sPAP group was higher than that in low sPAP group at high altitude (P<0.05), and there was a trend for decline in SOD level with increasing sPAP (P>0.05). Results from univariable linear regression analysis showed that the serum levels of OPN (r=0.32, P=0.002) and SOD (r=-0.22,P=0.032) were linearly correlated with sPAP in total cohort after high altitude exposure. Multivariate regression analysis showed that the serum levels of OPN(β=0.310,P=0.002) and SOD (β=-0.199,P=0.043) were independently associated with the levels of sPAP at high altitude. Conclusion: After acute high altitude exposure, the serum level of OPN is positively associated with sPAP, suggesting that OPN may be a novel bio-marker for predicting the increase of pulmonary pressure in response to acute high altitude exposure.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2020; 720:137514.

Abstract
Agricultural practices of no-till and crop rotations are critical to counteract the detrimental effects of monocultures and tillage operations on ecosystem services related to soil health such as microbial N cycling. The present study explored the main steps of the microbial N cycle, using targeted gene abundance as a proxy, and concerning soil properties, following 19 and 20 years of crop monocultures and rotations of corn (Zea mays L.), and soybean [Glycine max (L.) Merr.], either under no-till or chisel tillage. Real-time quantitative polymerase chain reaction (qPCR) was implemented to estimate phylogenetic groups and functional genes related to the microbial N cycle: nifH (N2 fixation), amoA (nitrification) and nirK, nirS, and nosZ (denitrification). Our results indicate that long-term crop rotation and tillage decisions affect soil health as it relates to soil properties and microbial parameters. No-till management increased soil organic matter (SOM), decreased soil pH, and increased copy numbers of AOB (ammonia oxidizing bacteria). Crop rotations with more corn increased SOM, reduced soil pH, reduced AOA (ammonia oxidizing archaea) copy numbers, and increased AOB and fungal ITS copy numbers. NirK denitrifier groups were also enhanced under continuous corn. Altogether, the more corn years included in a crop rotation multiplies the amount of N needed to sustain yield levels, thereby intensifying the N cycle in these systems, potentially leading to acidification, enhanced bacterial nitrification, and creating an environment primed for N losses and increased N2O emissions.

Abstract
Aims The emergence of carbapenem‐resistant Klebsiella pneumoniae (CRKP) strains has led to increased mortality and morbidity rates. Tigecycline, a new class of broad‐spectrum glycyl‐tetracycline antibiotics, has been used to target multi‐ and pan‐drug‐resistant bacterial infections. This study aimed to assess the molecular characteristics of CRKP in a tertiary hospital, and its susceptibility to tigecycline, to create a reference for hospital infection control and clinical drug use. Methods and Results We retrieved patient clinical information and CRKP characterization from medical records and detected the MIC of tigecycline using the micro‐broth dilution method. Multi‐locus sequence typing was performed, and antibiotic resistance genes associated with CRKP were detected by qPCR. A total of 166 CRKP strains were detected in the sputum, urine and blood among intensive care unit patients (average age, 69·6 years). The most infrequently observed resistance genes were amikacin resistance genes, followed by tobramycin resistance genes. KPC‐2, CTX‐M9 and CTX‐M1 were the most frequently detected resistance genes. Conclusions No strain was resistant to tigecycline (MIC ≥ 8 µg ml−1). Twenty‐four sequence types were identified, with ST11 being the most common type. Significance and Impact of the Study Clinicians and infection control experts should be aware of CRKP prevalence to facilitate clinical treatment and improve nosocomial infection control.

Abstract
Abstract
Introduction
Sodium oxybate (SXB) is a standard of care for the treatment of cataplexy and excessive daytime sleepiness in narcolepsy. JZP-258 is an oxybate product candidate (at same concentration as SXB) with 92% less sodium. JZP-258 dose adjustment during titration was evaluated.
Methods
At study entry, participants were taking SXB only, SXB+other anticataplectics, anticataplectics other than SXB, or were cataplexy treatment-naive. JZP-258 treatment began during a 12-week, open-label optimized treatment and titration period. Participants taking SXB only or SXB+other anticataplectics transitioned to JZP-258 at the same gram-for-gram dose as SXB and titrated to an efficacious and tolerable (optimal) dose from weeks 3-12. Participants taking other anticataplectics or who were anticataplectic-naive initiated JZP-258 at 4.5 g/night and were titrated to an optimal dose at 1-1.5 g/night/week (maximum total dose, 9 g/night). A 2-week stable-dose period and 2-week, double-blind, randomized withdrawal period followed.
Results
During the stable-dose period, total nightly JZP-258 dose (median [range]) was higher in participants taking SXB at study entry (SXB-only, 7.5 g [4.5-9.0], n=45; SXB+other anticataplectics, 9.0 g [6.0-9.0], n=14) compared with those not taking SXB (other anticataplectics, 7.5 g [4.5-9.0], n=23; anticataplectic-naive, 7.0 g [3.0-9.0], n=67), and dose adjustments were fewer. In most (69%) participants taking SXB at study entry who entered the stable-dose period, no change in dose was required (median [range] number of adjustments was 0 ([0-8]); for those with a change in dose, most changes were within one titration step (1.5 g/night). In participants not taking SXB at study entry, the median (range) number of adjustments was 3.0 (0-7).
Conclusion
Most participants taking SXB at study entry transitioned to JZP-258 treatment at the same dose with retained effectiveness. Participants not previously taking SXB achieved a tolerable and efficacious dose of JZP-258 after a median of 3 adjustments.

Abstract
Abstract
Introduction
Sodium oxybate (SXB) is a standard of care for the treatment of cataplexy and excessive daytime sleepiness in narcolepsy. JZP-258 is an oxybate product candidate with 92% less sodium. This analysis evaluated cataplexy-free days/week, as a measure of treatment impact, in a placebo-controlled randomized withdrawal study of JZP-258 treatment in patients with narcolepsy.
Methods
Treatment for cataplexy at study entry included 1) SXB (SXB-only); 2) SXB plus other anticataplectics (SXB+other); 3) anticataplectics other than SXB (other anticataplectics); or 4) cataplexy treatment-naive (anticataplectic-naive). Participants (aged 18-70 years with narcolepsy with cataplexy) began JZP-258 treatment during a 12-week, open-label, optimized treatment and titration period (OLOTTP), followed by a 2-week stable-dose period (SDP). Participants were randomized to receive placebo or continue JZP-258 treatment during a 2-week, double-blind, randomized withdrawal period (DBRWP).
Results
Of 201 enrolled participants, 134 comprised the efficacy population (placebo, n=65; JZP-258, n=69). Median (Q1, Q3) cataplexy-free days/week at first week of OLOTTP (while initiating JZP-258) by prior treatment were SXB-only, 5.8 (2.0, 7.0); SXB+other, 6.4 (5.0, 7.0); other anticataplectics, 4.0 (1.8, 6.0); anticataplectic-naive, 3.5 (0, 5.8). At end of SDP (on stable dose of JZP-258), median (Q1, Q3) cataplexy-free days/week were 6.0 (3.5, 7.0), 6.1 (1.4, 7.0), 6.0 (2.6, 7.0), and 6.2 (4.0, 7.0), respectively. Prior to randomization, there was no difference in median cataplexy-free days/week between participants to be randomized to placebo (6.0 [3.5, 7.0]) or JZP-258 treatment (6.0 [3.0, 7.0]); during DBRWP, median cataplexy-free days/week decreased in participants randomized to placebo (3.5 [0, 5.83]) but remained similar in participants randomized to continue JZP-258 treatment (5.6 [2.8, 7.0]). The overall safety profile of JZP-258 was similar to SXB.
Conclusion
Number of cataplexy-free days/week increased with JZP-258 treatment in participants previously naive to oxybate. Number of cataplexy-free days/week decreased during placebo exposure in participants randomized to placebo.

Abstract
The objective of this study was to explore the clinical significance of perioperative CTCs (circulating tumor cells) counts and EMT-CTCs (epithelial-mesenchymal transition-CTCs) in rectal cancer patients. A total of 30 patients with rectal cancer who underwent radical resection of rectal cancer at the Guangxi Zhuang Autonomous Region People's hospital were enrolled. Five ml peripheral blood was withdrawn from 30 patients with rectal cancer before the operation and seven days after the operation and at the corresponding time also from 20 healthy volunteers. CanPatrol™ CTC detection technique was used to enrich and identify CTCs and IER3 expression simultaneously. We found out that the preoperative total CTCs were correlated with lymph node metastasis (p=0.008) and tumor size, and mixed CTCs were closely correlated with lymph node metastasis (p=0.009). The number of IER3-positive total CTCs and mesenchymal CTCs were statistically associated with tumor size, p=0.034 and 0.043, respectively. The number of CTCs varied significantly before and after the operation in all patients (p=0.049). There were significant differences in CTCs variations between the open operation group and the laparoscopic operation group. In the laparoscopic operation group, the average number of single-cell CTCs was 6.9 before operation and 3.5 after the operation (p=0.013). In the open operation group, the average number of single-cell CTCs was 5.9 before operation and 4.2 after the operation. To conclude, surgery is associated with a decrease of CTCs in rectal cancer patients, especially in patients receiving laparoscopic surgery. The number of CTCs before the operation in rectal cancer patients is related to the size of tumors and regional lymph node metastasis. CTCs detection and characterization may be useful for clinical staging and lymph node dissection during operation.

Abstract
Nitrogen (N) could affect storage root growth and development of sweet potato. To manage external N concentration fluctuations, plants have developed a wide range of strategies, such as growth changes and gene expression. Five sweet potato cultivars were used to analyse the functions of N in regulating storage root growth. Growth responses and physiological indicators were measured to determine the physiological changes regulated by different N concentrations. Expression profiles of related genes were analysed via microarray hybridization data and qRT-PCR analysis to reveal the molecular mechanisms of storage root growth regulated by different N concentrations. The growth responses and physiological indicators of the five cultivars were changed by N concentration. The root fresh weight of two of the sweet potato cultivars, SS19 and GS87, was higher under low N concentrations compared with the other cultivars. SS19 and GS87 were found to be having greater tolerance to low N concentration. The expression of N metabolism and storage root growth related genes was regulated by N concentration in sweet potato. These results reveal that N significantly regulated storage root growth. SS19 and GS87 were more tolerant to low N concentration and produced greater storage root yield (at 30 days). Furthermore, several N response genes were involved in both N metabolism and storage root growth.
