Abstract
Objective: To investigate the prevalence of iron deficiency (ID) and iron deficiency anemia (IDA) in pregnant women in urban areas of China. Methods: The study was a national cross-sectional survey conducted from September 19th, 2016 to November 20th, 2016. According to the classification of the National Bureau of Statistics, all survey sites were set up in 6 regions of the country.Pregnant women were continuously selected using multistage stratified sampling. A total of 12 403 pregnant women were collected and examined for serum ferritin and hemoglobin levels. Results: The median serum ferritin level during pregnancy was 20.60 μg/L (11.78-36.98 μg/L) , the hemoglobin level was (118±12) g/L. With the progress of pregnancy, the levels of serum ferritin and hemoglobin decreased gradually. The median serum ferritin levels in the first, second trimester and third trimester were 54.30 μg/L (34.48-94.01 μg/L) , 28.60 μg/L (16.40-50.52 μg/L) , and 16.70 μg/L (10.20-27.00 μg/L) respectively (P<0.01) . The mean hemoglobin levels were (127±10) g/L, (119±11) g/L and (117±11) g/L respectively (P<0.01) . The prevalence of ID in urban pregnant women was 48.16% (5 973/12 403) , and IDA prevalence was 13.87% (1 720/12 403) . The prevalence of IDA in the first, second trimester and third trimester were 1.96% (20/1 019) , 8.40% (293/3 487) and 17.82% (1 407/7 897) ,respectively (P<0.01) . The prevalence of standardized ID and IDA were significantly different in various regions of China (P<0.01) . The standardized prevalence of ID were relatively higher in East China and Northeast China, 57.37% and 53.41% respectively, while it was the lowest in Southwest China, 30.51%. The standardized prevalence of IDA in South Central, Northwest, and East China were relatively high, 21.30%, 16.97% and 17.53% respectively, and the standardized prevalence of IDA in Southwest China was the lowest, 5.44%, the differents in various regions were significant (all P<0.01) . Conclusion: The current phenomenon of ID and IDA in pregnant women is still very common, and nutrition and health care during pregnancy should be strengthened.

Abstract
Melanoma is the main cause of death in patients with skin cancer. While the pathogenesis of cutaneous melanoma is poorly understood, increasing evidence shows that epidermal growth factor (EGF) may be involved. Herein, we tested the hypothesis that down-regulation of EGFL7 inhibits development and progression of human cutaneous melanoma (CM). Initially, we performed immunohistochemical analysis of EGFL7 in 130 specimens and the findings indicated that EGFL7 was highly expressed in CM. The expressions of EGFL7 and Notch signaling pathway-related genes in CM were then measured by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and Western blot assay. In order to assess biological functions of EGFL7 in CM we up-regulated or down-regulated endogenous EGFL7 using EGFL7-OE or shRNA against EGFL7 in the A375 CM cell line. To better understand the pivotal role of Notch signaling pathway in CM, we blocked this pathway in A375 cells by inhibitor treatment. Finally, tumor xenograft in nude mice was performed to test the in vivo tumorigenesis of the transfected A375 cells. While EGFL7 activated the Notch signaling pathway in CM, gain- and loss-of-function studies established that decreased EGFL7 inhibited cell proliferation and promoted apoptosis in A375 cells. Moreover, down-regulated EGFL7 suppressed in vivo tumorigenesis. Most importantly, we determined that down-regulating EGFL7 inhibited CM development by suppressing the Notch signaling pathway. The combined findings define potential roles of decreased EGFL7 as inhibitors of CM development by suppressing the Notch signaling pathway, and EGFL7 may therefore be a novel therapeutic target in cutaneous melanoma patients.

Abstract
Despite advances in diagnosis and treatment, the survival of non-small cell lung cancer (NSCLC) patients is poor. Further understanding of the disease mechanism and treatment strategies is required. Copines are a family of calcium-dependent phospholipid-binding proteins that are evolutionally conserved in various eukaryotic organisms and protists. Copine 1, encoded by CPNE1, is a soluble membrane-binding protein, which includes two tandem C2 domains at the N-terminus and an A domain at the C-terminus. A previous study reported that Copine 1 binds with various intracellular proteins via its A domain and C omain. However, the role of CPNE1 in lung cancer remains unclear. In the presented study, CPNE1 expression level was demonstrated to be positively associated with the stage (P=0.002) and significantly associated with lymph node status (P=0.011) and distant metastasis (P=0.042). Furthermore, the function of CPNE1 in regulation of cell growth, migration and invasion was investigated, and it was demonstrated that knockdown of CPNE1 inhibits the cell cycle in NSCLC cells. Collectively, these data suggest that CPNE1 is an oncogene in NSCLC and serves an important role in tumorigenesis of NSCLC progression.

Abstract
Mesenchymal stem cells (MSCs) constitute an important repair system, but may be impaired by exposure to cardiovascular risk factors. Consequently, adipose tissue-derived MSCs from pigs with the metabolic syndrome (MetS) show decreased vitality. A growing number of microRNAs (miRNAs) are recognized as key modulators of senescence, but their role in regulating senescence in MSC in MetS is unclear. We tested the hypothesis that MetS upregulates in MSC expression of miRNAs that can serve as post-transcriptional regulators of senescence-associated (SA) genes. MSCs were collected from swine abdominal adipose tissue after 16 weeks of Lean or Obese diet ( n = 6 each). Next-generation miRNA sequencing (miRNA-seq) was performed to identify miRNAs up-or down-regulated in MetS-MSCs compared with Lean-MSCs. Functional pathways of SA genes targeted by miRNAs were analyzed using gene ontology. MSC senescence was evaluated by p16 and p21 immunoreactivity, H2AX protein expression, and SA-β-Galactosidase activity. In addition, gene expression of p16, p21, MAPK3 (ERK1) and MAPK14, and MSC migration were studied after inhibition of SA-miR-27b. Senescence biomarkers were significantly elevated in MetS-MSCs. We found seven upregulated miRNAs, including miR-27b, and three downregulated miRNAs in MetS-MSCs, which regulate 35 SA genes, particularly MAPK signaling. Inhibition of miR-27b in cultured MSCs downregulated p16 and MARP3 genes, and increased MSC migration. MetS modulates MSC expression of SA-miRNAs that may regulate their senescence, and the p16 pathway seems to play an important role in MetS-induced MSC senescence.

Abstract
Background Despite advances in diagnosis and treatment, the survival of non-small cell lung cancer (NSCLC) patients remains poor. There is therefore a strong need to identify potential molecular targets for the treatment of NSCLC. In the present study, we investigated the function of CPNE1 in the regulation of cell growth, migration and invasion. Methods Quantitative real-time PCR (qRT-PCR) was used to detect the expression of CPNE1 and miR-335-5p. Western blot and immunohistochemical assays were used to investigate the levels of CPNE1 and other proteins. Flow cytometry was used to determine cell cycle stage and apoptosis. CCK-8 and clonogenic assays were used to investigate cell proliferation. Wound healing, migration and invasion assays were used to investigate the motility of cells. A lung carcinoma xenograft mouse model was used to investigate the in vivo effects of CPNE1 overexpression. Results We observed that knockdown of CPNE1 and increased expression of miR-335-5p inhibits cell proliferation and motility in NSCLC cells, and found that CPNE1 was a target of miR-335-5p. In addition, our data indicated that CPNE1 inhibition could improve the clinical effects of EGFR-tyrosine kinase inhibitors. Conclusions The present results indicate that CPNE1 may be a promising molecular target in the treatment of NSCLC.

Abstract
The alterations induced in gut microbiota by tacrolimus may affect immune function and organ transplantation. Mice were treated with high-dose tacrolimus for 14 days. The fecal microbiota were analyzed by pyrosequencing the 16S rRNA genes, and the effect on metabolism was predicted using the sequence data. The subgroups of T cells in the serum, gut-associated lymphoid tissue, and draining lymph nodes were determined by flow cytometry. Tacrolimus treatment significantly altered the relative abundance of Allobaculum, Bacteroides, and Lactobacillus and CD4+ CD25hi FoxP3+ regulatory T cells in the colonic mucosa and the circulation. These were significantly increased after either tacrolimus treatment or treatment by fecal microbiota transfer from tacrolimus-treated donors. Further, treatment with low-dose tacrolimus plus fecal microbiota transfer from high-dose tacrolimus-altered mice increased skin allograft survival rate in a skin transplantation model. Thus, high-dose tacrolimus alters the compositions and taxa of the gut microbiota. Administration of these conditioned gut microbiota plus low-dose tacrolimus resulted in regulation of colonic and systemic immune responses and an increased allograft survival rate. This study demonstrated a new strategy for controlling allograft rejection by combining an immunosuppressive agent with gut microbiome transplantation.

Abstract
OBJECTIVES To validate the analysis capability of RapidHIT™ 200 system for four kinds of routine forensic samples and the recyclable capability of template, template DNA and PCR products in the process of twice duplicate detection. METHODS The buccal swabs underwent the test twice by RapidHIT™ 200 system, and the template DNA and PCR products that arose in the system were also tested for two times. After four kinds of routine forensic samples were detected by RapidHIT™ 200 system, the follow-up tests of the template, template DNA and PCR products that arose in the system were performed. RESULTS The STR loci could be detected in the buccal swabs by the system for the first time. However, part of the STR loci lost during the second test. And the peak value obtained in the second test was significantly reduced than the one in the first time. The average STR loci detection rates of the template DNA and PCR products were both less than 50% in the second test, which were significantly reduced than that in the first test. In addition, the analysis capability of the system for the tissues and buccal swabs was better than that for the blood and cigarette butts. Compared with the first test, the STR loci detection rate of the tested items, template DNA and PCR products decreased with the numbers of tests. CONCLUSIONS RapidHIT™ 200 system is more effective in retesting buccal swabs than other samples, whereas the items, DNA template, PCR products obtained in the first and second time cannot be directly used for the further application and study of forensic medicine.

Abstract
Abstract
Background
Lymph node status is crucial in determining the prognosis for early oesophageal squamous cell carcinoma (SCC). This study aimed to develop and validate a nomogram for the prediction of lymph node metastasis in patients with early SCC.
Methods
A prediction model was developed in a derivation cohort of patients with clinicopathologically confirmed early SCC. Patients who underwent oesophagectomy for pT1 SCC between January 2010 and December 2013 were identified from an institutional database. Risk factors for lymph node metastasis were assessed using a binary logistic regression modelling technique. A nomogram for the prediction of lymph node metastasis was constructed using the results of multivariable analyses. For internal validation, bootstraps with 1000 resamples were performed. The predictive performance of the nomogram was measured by Harrell's concordance index (C-index). An independent cohort from the same hospital was used to validate the nomogram. This cohort included consecutive patients with early SCC who underwent oesophagectomy from January 2014 to December 2015.
Results
The derivation cohort included 281 patients. Four variables associated with lymph node metastasis were included in the model: depth of tumour invasion (odds ratio (OR) 4·37, 95 per cent c.i. 1·59 to 12·03; P = 0·004), grade of differentiation (OR 4·47, 1·02 to 19·70; P = 0·048), tumour size (OR 2·52, 1·11 to 5·75; P = 0·028) and lymphovascular invasion (OR 6·58, 2·54 to 17·05; P < 0·001). The C-index was 0·790 (95 per cent c.i. 0·717 to 0·864) in the derivation cohort and 0·789 (0·709 to 0·869) for the validation cohort (198 patients).
Conclusion
A validated nomogram for patients with early oesophageal SCC can predict the risk of lymph node metastasis.

Abstract
BACKGROUND Skin blood flow is believed to link with many diseases, and shows a significant heterogeneity. There are several papers on basal cutaneous microcirculation perfusion in different races, while the data in Chinese is vacant. OBJECTIVE The aim was to establish the database of absolute fundamental supply of skin blood flow in the Chinese Han population. METHODS With a full-field laser perfusion imager (FLPI), the skin blood flow can be quantified. Cutaneous perfusion values were determined in 17 selected skin areas in 406 healthy participants aged between 20 and 80 years (mean 35.05 ± 11.33). Essential parameters such as weight, height were also measured and values of BMI were calculated. The perfusion values were reported in Arbitrary Perfusion Units (APU). RESULTS The highest cutaneous perfusion value fell on eyelid (931.20 ± 242.59 in male and 967.83 ± 225.49 in female), and pretibial had the lowest value (89.09 ± 30.28 in male and 85.08 ± 33.59 in female). The values were higher in men than women on the bank of fingertips, nose, forehead, cheek, neck and earlobe (P < .05). Perfusion values on stretch and flexion side of forearm had negative correlation with age (P = .01 and P = 4.88 × 10-3 , respectively) in male. Abdomen was negatively correlated with BMI in both gender (P = .02, respectively). CONCLUSIONS Skin blood flow values vary with skin regions. There is a tendency to measure higher perfusion values in men than in women. And the values are irrelevant with age or BMI.

Abstract
Liver biopsy is not routinely performed in treated chronic hepatitis B. Liver stiffness measurement has been validated for noninvasive liver fibrosis assessment in pretreatment chronic hepatitis B but has not been assessed for fibrosis monitoring during antiviral therapy. Liver stiffness was systemically monitored by Fibroscan® every 6 months in a cohort of patients with hepatitis B receiving antiviral therapy and compared with liver biopsies at baseline and week 104. A total of 534 hepatitis B e antigen-positive treatment-naive patients receiving telbivudine-based therapy with qualified liver stiffness measurement at baseline and week 104 were analyzed, 164 of which had adequate paired liver biopsies. Liver stiffness decreased rapidly (-2.2 kPa/24 weeks) in parallel with alanine aminotransferase (ALT) from 8.6 (2.6-49.5) kPa at baseline to 6.1 (2.2-37.4) kPa at week 24. Interestingly, liver stiffness decreased slowly (-0.3 kPa/24 weeks) but continually from week 24 to week 104 (6.1 vs 5.3 kPa, P < .001) while ALT levels remained stable within the normal range. More importantly, liver stiffness declined significantly irrespective of baseline ALT levels and liver necroinflammation grades. From baseline to week 104, the proportion of patients with no or mild fibrosis (Ishak, 0-2) increased from 74.4% (122/164) to 93.9% (154/164). Multivariate analysis revealed that percentage decline of 52-week liver stiffness from baseline was independently associated with 104-week liver fibrosis regression (odds ratio, 3.742; P = .016). Early decline of 52-week liver stiffness from baseline may reflect the remission of both liver inflammation and fibrosis and was predictive of 104-week fibrosis regression in treated patients with chronic hepatitis B.

Abstract
BACKGROUND The U.S. Food and Drug Administration recently issued a safety communication requiring new warnings of increased leg and foot amputation risk be added to canagliflozin drug labelling. However, the risk associated with other sodium-glucose co-transporter 2 inhibitors (SGLT2i) remains uncertain. AIM This meta-analysis aimed to evaluate the potential risks of diabetic foot syndrome (DFS) and amputation associated with SGLT2i. METHODS Relevant databases were searched from inception to June 14, 2017 to identify randomized controlled trials (RCTs) that evaluated risks of DFS and amputation associated with SGLT2i use. A random effects model was performed to estimate odds ratios (ORs) and 95% confidence intervals (CIs) using STATA 14. RESULTS Fourteen RCTs involving 26,167 patients were eligible for this meta-analysis. SGLT2i were not significantly associated with increased risk of DFS compared with placebo (OR 1.05, 95% CI: 0.58-1.89). No significant association was observed in the subgroup and sensitivity analysis on DFS risk either. Although SGLT2i, as a class, were not significantly associated with amputation risk (OR 1.40, 95% CI: 0.81-2.41), subgroup analysis showed an increased incidence of amputation in participants using canagliflozin (OR 1.89, 95% CI: 1.37-2.60), compared with oral anti-diabetic drugs and placebo, but not in those using empagliflozin (OR 1.02, 95% CI: 0.71-1.48). CONCLUSION Current evidence from RCTs suggests that canagliflozin may be positively associated with an increased risk of amputation. Due to limited data, large-scale studies are required to further clarify the association between amputation and individual SGLT2i drugs.

Abstract
We report on the smooth transition between gradient-banded velocity profiles with a sharp interface and curved velocity profiles, both resulting from strong shear-thinning dispersions of concentrated xanthan (a highly charged poly-saccharide). Pronounced shear-banded flow, where two extended shear-bands are separated by a relatively sharp interface, is observed in a limited range of shear rates, at very low ionic strength and at a high concentration, using heterodyne light scattering to measure spatially resolved velocity profiles. The width of the interface between the coexisting shear-bands broadens to span a sizable fraction of the gap of the shear cell, either by changing the shear rate, by lowering the concentration, or by increasing the ionic strength. The broadening results in a smooth transition to highly curved velocity profiles and is connected to a disappearing flow birefringence. Thus, these experiments show that the classic shear-banding instability can give rise to highly curved velocity profiles, due to the existence of broad interfaces between the bands, with an extent of the order or larger than the cell gap width. This observation may aid to resolve the ongoing dispute concerning shear-banding of highly entangled polymeric systems, suggesting that the curved velocity profiles that have been observed in the past are in fact shear-banded states with an unusually broad interface.

Abstract
Objective: To analyze the incidence and causes of stillbirth in 11 hospitals of Guangdong province, and to explore the appropriate interventions. Methods: Clinical data of stillbirth in 11 hospitals of Guangdong province were collected from January 2014 to December 2016. The gestational weeks, causes, maternal conditions and other factors were analyzed. Results: (1) From 2014 to 2016, 103 472 newborns were delivered in the 11 hospitals, and the number of stillbirth was 2 204, with the incidence of 2.13%. Among them, 0.71%(738/103 472) was therapeutic induction, 1.42%(1 066/103 472) was natural stillbirth. At different gestational age (<28 weeks, 28-<37 weeks and ≥37 weeks), the incidence of stillbirth was 55.63% (1 226/2 204), 28.45% (627/2 204) and 15.92% (351/2 204), respectively, with statistically significant difference (P<0.01). (2) For stillbirth<28 weeks, the first reason was therapeutic induction, accounting for 53.34% (654/1 226). For stillbirth during 28-37 weeks, pre-eclampsia was the major cause, accounting for 40.67% (255/627). And for full-term stillbirth, the causes were umbilical cord factors (19.37%, 68/351), abnormal labor (17.09%, 60/351). (3) In all the stillbirth cases, the incidence of fetal growth restriction (FGR) <28 weeks was significantly higher than that during 28-37 weeks [23.49% (288/1 226) vs 18.02% (113/627) , P<0.01]. (4) The stillbirth rate during labor was significantly higher in women ≥35 years old than in younger women [63.88% (191/299) vs 36.12% (108/299) ; χ(2)=9.346, P=0.000]. For the causes of stillbirth during labor, the incidence of severe maternal obstetrical complications [61.11% (33/54) vs 38.89% (21/54) ; χ(2)=3.323, P=0.002], abnormal labor [65.82% (52/79) vs 34.18% (27/79) ; χ(2)=4.067, P=0.001] and abnormal fetal position [66.63% (26/39) vs 33.37% (13/39) ; χ(2)=3.002, P=0.013] were higher in women ≥35 years old than in younger women. (5) Cesarean section during labor accounted for 33.77% (101/299) of stillbirth, including 76 cases of emergency cesarean section or converted to cesarean section during labor. Conclusions: (1) The incidence of stillbirth in the 11 hospitals is high, and the causes are different at different gestational ages, therefore, different interventions are needed to reduce the incidence in different gestational weeks. Supervision of therapeutic induction should be strengthened <28 gestational weeks; standard management of pregnancy might decrease the occurrence of natural death ≥28 weeks. (2) Attention should be paid to fetal body weight during pregnancy, especially FGR. (3) The stillbirth rate is high in elderly pregnant women, so it is important to strengthen the management of the elderly pregnant women.
