Abstract
The estrogen receptor (ER) has played an important role in breast cancer development and progression and is a central target for anticancer drug discovery. In order to develop novel selective ERα modulators (SERMs), we designed and synthesized 18 novel 3-aryl-4-anilino-2H-chromen-2-one derivatives based on previously reported lead compounds. The biological results indicated that most of the compounds presented potent ERα binding affinity and possessed better anti-proliferative activities against MCF-7 and Ishikawa cell lines than the positive control tamoxifen. The piperidyl substituted compounds such as 16d and 18d demonstrated strong ERα binding affinities and excellent anti-proliferative activities respectively. Compound 18d displayed the most potent ERα binding affinity with RBA value of 2.83%, while 16d exhibited the best anti-proliferative activity against MCF-7 cells with IC50 value of 4.52±2.47μM. Further molecular docking studies were also carried out to investigate binding pattern of the newly synthesized compounds with ERα. All these results together with the structure-activity relationships (SARs) indicated that these 3-aryl-4-anilino-2H-chromen-2-one derivatives with basic side chain could serve as promising leads for further optimization as novel SERMs.

Abstract
Records of the Ediacaran carbon cycle (635-541 million years ago) include the Shuram excursion (SE), the largest negative carbonate carbon isotope excursion in Earth history (down to -12‰). The nature of this excursion remains enigmatic given the difficulties of interpreting a perceived extreme global decrease in the δ13 C of seawater dissolved inorganic carbon. Here, we present carbonate and organic carbon isotope (δ13 Ccarb and δ13 Corg ) records from the Ediacaran Doushantuo Formation along a proximal-to-distal transect across the Yangtze Platform of South China as a test of the spatial variation of the SE. Contrary to expectations, our results show that the magnitude and morphology of this excursion and its relationship with coexisting δ13 Corg are highly heterogeneous across the platform. Integrated geochemical, mineralogical, petrographic, and stratigraphic evidence indicates that the SE is a primary marine signature. Data compilations demonstrate that the SE was also accompanied globally by parallel negative shifts of δ34 S of carbonate-associated sulfate (CAS) and increased 87 Sr/86 Sr ratio and coastal CAS concentration, suggesting elevated continental weathering and coastal marine sulfate concentration during the SE. In light of these observations, we propose a heterogeneous oxidation model to explain the high spatial heterogeneity of the SE and coexisting δ13 Corg records of the Doushantuo, with likely relevance to the SE in other regions. In this model, we infer continued marine redox stratification through the SE but with increased availability of oxidants (e.g., O2 and sulfate) limited to marginal near-surface marine environments. Oxidation of limited spatiotemporal extent provides a mechanism to drive heterogeneous oxidation of subsurface reduced carbon mostly in shelf areas. Regardless of the mechanism driving the SE, future models must consider the evidence for spatial heterogeneity in δ13 C presented in this study.

Abstract
Objective: To evaluate the specificity and limitations of sacroiliac joint magnetic resonance imaging (MRI) in the diagnosis of axial spondyloarthritis (SpA)in patients with chronic low back pain. Methods: We retrospectively analyzed clinical data of 390 patients with chronic low back pain in Department of Rheumatology, the PLA General Hospital from January 2013 to December 2015, including clinical manifestations, laboratory examinations and MRI data of sacroiliac joints. Results: There were 238 men and 152 women recruited. A total of 326 cases were diagnosed as axial SpA, including 216 men and 110 women with mean age (27.10±8.64) years and mean duration (7.64±3.50) months. Among these 326 patients, 243 (74.5%) were HLA-B27 positive. The other 64 patients were considered as diagnoses rather than SpA (non-SpA), consisting of 22 men and 42 women with mean age (31.29±7.76) years and mean duration (5.75±2.90)months. Non-SpA group had 10 (15.6%) patients with HLA-B27 positive. There were 68.1% and 65.0% SpA patients showing bone marrow edema and bone erosion of sacroiliac joint in MRI imaging respectively. Although there were 25.0% non-SpA patients with bone marrow edema and 7.8% with bone erosion in MRI of sacroiliac joint, the scores of bone marrow edema 0.00(0.00, 0.75) and bone erosion [0.00(0.00, 0.00)] were significantly lower compared with those in axial SpA group [bone marrow edema scores 2.00(0.00, 4.00), bone erosion scores 1.00(0.00, 3.00); P<0.05]. The scores of fat infiltration [1.00(0.00, 4.25), 1.00(0.00, 4.00)] and bone sclerosis [0.00(0.00, 1.00), 0.00(0.00, 1.75)] were not statistically different between two groups. Diagnostic sensitivity of bone marrow edema and bone erosion for axial SpA were 56.4% and 64.1% respectively, specificity were 93.8% and 92.2% respectively. The positive predictive value of bone marrow edema and bone erosion for axial SpA were 9.09 and 8.21, negative predictive value were 0.46 and 0.38.Diagnositic sensitivity of fatty infiltration and bone sclerosis for axial SpA group were 29.1% and 57.7%, specificity were 64.1% and 46.9%.The positive predictive value of fatty infiltration and bone sclerosis for axial SpA were 0.81 and 1.08, negative predictive value were 1.10 and 0.90. Conclusion: Sacroiliac joint MRI is a valuable method to diagnose axial SpA in patients with chronic low back pain. Yet it still has some limitations. Clinical presentations and spinal MRI would be helpful in some patients.

Abstract
OBJECTIVE To explore the causes of rectal injuries during laparoscopic peritoneal vaginoplasty (Luohu operation) and assess measures that can be taken to increase safety of the operation. MATERIALS AND METHODS Data of patients with rectal injuries that occurred during Luohu vaginoplasty were analyzed retrospectively. RESULTS Three hundred and six patients received Luohu vaginoplasty. Rectal injuries occurred in 13 patients (4.2%). All patients recovered after intraoperative repair or postoperative rectovaginal fistula repair, performed within three to six months. Full display of the anatomical structures at the bottom of the pelvic cavity and successful construction of the vaginal tunnel are the two most important requirements for reducing the risk of rectal injury in laparoscopic vaginoplasty. In repair of fistulae postoperatively, it is important that resection of tissues or scars around the fistulae be avoided in order to reduce the chance of a injuries caused by diverting colostomy or colostomy closure. CONCLUSION Laparoscopic vaginoplasty is a generally safe procedure, but rectal injury can occur. Retaining the tissues or scars around the rectovaginal fistula can be successfully repaired, either when they are recognized during the operation or within a few months postoperatively.

Abstract
Purpose: To explore the antihyperglycemic and antioxidant effects of Fructus Hordei Germinatus extract (FHGE) in diabetic rats.Methods: The aqueous extract of FHG was obtained by steeping the dried Fructus Hordei Germinatus in water at 60oC three times, each for 1 h before first drying in an oven and then freeze-drying the last extract thus obtained. Antihyperglycemic effect was measured by blood glucose and plasma insulin levels. Oxidative stress was evaluated in liver and kidney by antioxidant markers, viz, lipid peroxidation (LPO), superoxide dismutase (SOD), reduced glutathione (GSH), glutathione peroxidase (GPx) and catalase (CAT), while blood serum levels of creatinine and urea were also determined in both diabetic control and treated rats.Results: Compared with diabetic rats, oral administration of FHGE at a concentration of 20, 40 and 80 mg/kg daily for 45 days showed a significant decrease in fasting blood glucose (p < 0.05) and increased insulin (p < 0.05) level,. Furthermore, it significantly reduced biochemical parameters (serum creatinine and serum urea, p < 0.05)). The treatment also resulted in significant increase in GSH, GPx (p < 0.05), SOD and CAT (p < 0.05), as well as decreased LPO (p < 0.05) level in the liver and kidney of diabetic rats.Conclusion: The results suggest that FHGE may effectively normalize the impaired antioxidant status in streptozotocin-induced diabetes in a dose-dependent manner. FHGE has a protective effect against lipid peroxidation by scavenging free radicals and is thus capable of reducing the risk of diabetic complications.Keywords: Fructus hordei Germinatus, Diabetic, Antihyperglycemic, Lipid peroxidation, Antioxidant, Fasting blood glucose, Creatinine, Urea

Abstract
Nude mice are important in vivo model for characterization of cell malignancy behavior; however, many cancer cells fail to form tumors in it. Understanding this defective mechanism may provide novel insights into tumorigenesis and how tumor cells escape innate immunity. Whole-genome sequencing was conducted on two gastric cancer (GC) cells, BGC823 and AGS, which do and do not form tumors in nude mice, to identify their genomic differences relevant to natural killer (NK) cells. We found that the tumorigenic capacity of human GC cell lines was dependent on the recruitment and activation of NK cells in xenograft tumors. We used whole-genome sequence (WGS) on GC cell lines to identify potential genes controlling susceptibility to NK-mediated killing. The tumorigenic cell line BGC823 expressed high levels of HLA-I because of copy gain and was resistant to NK cell killing. In contrast, another cell line AGS expressing low levels of HLA-I with activated NKp30/MAPK/IL-12 (interleukin-12) or IL-2 (interleukin-2) pathway was susceptible to NK lysis. Treatment of tumor bearing mice with systemic administration of IL-12 in combination with intratumor injection of anti-HLA-I antibody significantly increased NK cell recruitment into xenograft tumors, which became sensitive to NK killing, resulting in reduced tumor progression. In human GC specimens, decreased HLA-I expression and increased NK cells surrounding tumor cells were correlated with decreased metastasis potential and better prognosis of patients. Our results provide a mechanistic basis for GC cells to escape NK lysis and a promising prospect of NK immunotherapy for GC cells.

Abstract
Obesity is a strong determinant of blood pressure. Uncertainty remains, however, about which indices of adiposity most strongly predict blood pressure, particularly among those who were relatively lean, such as those from rural China. We analyzed cross-sectional data on 55 687 (38.3% men) participants aged 30–79 years who were enrolled into the China Kadoorie Biobank from a rural county in southwest of China during 2004–2008. Measured body mass index (BMI) and waist circumference (WC) were related to blood pressure in multivariable linear regression analyses. The overall mean values of BMI, WC, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 23.3 kg m−2, 78.0 cm, 129.2 mm Hg and 77.2 mm Hg, respectively. There was a strongly positive, and apparently linear, relationship of BMI and WC with blood pressure, with 1 s.d. higher BMI associated with 4.3/2.3 mm Hg higher SBP/DBP and 1 s.d. WC associated with 3.8/2.1 mm Hg (P<0.0001). Additional adjustment for WC only slightly attenuated the association of BMI with blood pressure, whereas additional adjustment for BMI almost completely eliminated the association of WC with blood pressure. Our findings suggest that in relatively lean Chinese adults, general adiposity is more strongly assciated with blood pressure than central adiposity.

Abstract
The A(n+1)B(n)O(3n+1) Ruddlesden-Popper homologous series offers a wide variety of functionalities including dielectric, ferroelectric, magnetic and catalytic properties. Unfortunately, the synthesis of such layered oxides has been a major challenge owing to the occurrence of growth defects that result in poor materials behaviour in the higher-order members. To understand the fundamental physics of layered oxide growth, we have developed an oxide molecular beam epitaxy system with in situ synchrotron X-ray scattering capability. We present results demonstrating that layered oxide films can dynamically rearrange during growth, leading to structures that are highly unexpected on the basis of the intended layer sequencing. Theoretical calculations indicate that rearrangement can occur in many layered oxide systems and suggest a general approach that may be essential for the construction of metastable Ruddlesden-Popper phases. We demonstrate the utility of the new-found growth strategy by performing the first atomically controlled synthesis of single-crystalline La3Ni2O7.

Abstract
AIMS To examine the relationship of self-reported diabetes, and of random blood glucose levels among individuals without known diabetes, with the prevalence of cardiovascular disease in Chinese adults. METHODS We examined cross-sectional data from the China Kadoorie Biobank of 0.5 million people aged 30-79 years recruited from 10 diverse regions of China in the period 2004-2008. Logistic regression was used to estimate the odds ratios of prevalent cardiovascular disease associated with self-reported diabetes, and with measured random blood glucose levels among participants with no history of diabetes, adjusting simultaneously for age, sex, area, education, smoking, alcohol, blood pressure and physical activity. RESULTS A total of 3.2% of participants had self-reported diabetes (men 2.9%; women 3.3%) and 2.8% had screen-detected diabetes (men 2.6%; women 2.8%), i.e. they had no self-reported history of diabetes but a blood glucose level suggestive of a diagnosis of diabetes. Compared with individuals without a history of diabetes, the odds ratios associated with self-reported diabetes were 2.18 (95% CI 2.06-2.30) and 1.88 (95% CI 1.75-2.01) for prevalent ischaemic heart disease and stroke/transient ischaemic attack, respectively. Among participants without self-reported diabetes there was a positive association between random blood glucose and ischaemic heart disease and stroke/transient ischaemic attack prevalence (P for trend <0.0001). Below the diabetic threshold (<11.1 mmol/l) each additional 1 mmol/l of random blood glucose was associated with 4% (95% CI 2-5%) and 5% (95% CI 3-7%) higher odds of prevalent ischaemic heart disease and stroke/transient ischaemic attack, respectively. CONCLUSIONS In this adult Chinese population, self-reported diabetes was associated with a doubling of the odds of prevalent cardiovascular disease. Below the threshold for diabetes there was still a modest, positive association between random blood glucose and prevalent cardiovascular disease.

Abstract
OBJECTIVE In this study, we performed a case-control association analysis to determine whether the candidate genes COL2A1 and IGF-1 are susceptibility genes for mandibular prognathism (MP). METHODS Eleven and five single-nucleotide polymorphisms (SNPs) located in COL2A1 and IGF-1, respectively, were selected and genotyped in 211 cases and 224 controls. The individual SNPs and the relevant haplotypes were analyzed and tested for an association with MP, to identify genes potentially associated with MP. RESULTS In the analysis of individual SNPs, the SNP rs1793953 in the COL2A1 gene showed a possible association with MP with regard to allelic frequency and genotypic distribution (p = 0.031; p = 0.025, respectively) in the 211 cases and 224 controls. The A allele of rs1793953 was associated with a significantly decreased risk of MP (OR: 0.74; 95% CI: 0.58-0.97). Linkage disequilibrium and haplotype analysis revealed that MP was not associated with haplotypes that included the rs1793953 alleles. IGF-1 gene did not show the association with MP. CONCLUSION An association between polymorphism in the COL2A1 gene and MP was observed. The results suggested that the COL2A1 gene could be a new susceptibility gene for use in the study of genetic risk factors for MP.
