Abstract
The randomized, multicenter, double-blind, placebo-controlled, phase III PEONY trial (NCT02586025) demonstrated significantly improved total pathologic complete response (primary endpoint) with dual HER2 blockade in HER2-positive early/locally advanced breast cancer, as previously reported. Here, we present the final, long-term efficacy (secondary endpoints: event-free survival, disease-free survival, overall survival) and safety analysis (62.9 months' median follow-up). Patients (female; n = 329; randomized 2:1) received neoadjuvant pertuzumab/placebo with trastuzumab and docetaxel, followed by adjuvant 5-fluorouracil, epirubicin, and cyclophosphamide, then pertuzumab/placebo with trastuzumab until disease recurrence or unacceptable toxicity, for up to 1 year. Five-year event-free survival estimates are 84.8% with pertuzumab and 73.7% with placebo (hazard ratio 0.53; 95% confidence interval 0.32-0.89); 5-year disease-free survival rates are 86.0% and 75.0%, respectively (hazard ratio 0.52; 95% confidence interval 0.30-0.88). Safety data are consistent with the known pertuzumab safety profile and generally comparable between arms, except for diarrhea. Limitations include the lack of ado-trastuzumab emtansine as an option for patients with residual disease and the descriptive nature of the secondary, long-term efficacy endpoints. PEONY confirms the positive benefit:risk ratio of neoadjuvant/adjuvant pertuzumab, trastuzumab, and docetaxel treatment in this patient population.

Monitoring trends in the absolute lymphocyte count and the neutrophil-to-lymphocyte ratio in patients with breast cancer receiving eribulin. BMC Cancer 2024; 24:195.

Abstract
BACKGROUND Studies have shown that the absolute lymphocyte count (ALC) and the neutrophil-to-lymphocyte ratio (NLR) are related to the outcomes in patients with breast cancer receiving specific chemotherapies. However, the reports have focussed on the initial blood test and there is a lack of evidence or data to support that dynamic changes of ALC or NLR are associated with the patients' survival outcomes. METHODS We retrospectively reviewed electronic medical records from patients with breast cancer treated with eribulin from 2015 to 2019 at our institution. Blood test data were available prior to starting eribulin (baseline), and at 1, 3 and 6 months after initiating eribulin. We classified the patients into ALC and NLR high and low groups using the following cut-offs: 1000/µl for ALC and 3 for NLR. We defined ALC and NLR trends as increasing or decreasing compared with the initial data. We assessed the associations between the ALC and NLR with progression-free survival and overall survival. RESULTS There were 136 patients with breast cancer treated with eribulin. Of these patients, 60 had complete blood tests and follow-up data. Neither a high ALC nor a low baseline NLR was associated with the survival outcome. One month after initiating eribulin treatment, a high ALC and a low NLR were significantly associated with longer progression-free survival (p = 0.044 for each). Three months after initiating eribulin, a high ALC was significantly associated with better overall survival (p = 0.006). A high NLR at 3 or 6 months after initiating eribulin was associated with worse overall survival (p = 0.017 and p = 0.001, respectively). The ALC and NLR trends across times were not associated with survivals. CONCLUSION We showed that 1, 3 and 6 months after initiating eribulin, a high ALC and a low NLR may be related to the patients' survival outcomes. The ALC and NLR trends were not associated with survival. Accordingly, we believe patients who maintain a high ALC and a low NLR may have better clinical outcomes after initiating eribulin.

Abstract
Phage therapy is one of the most important tools for the treatment of infections with multi-drug resistant bacteria. Such phages are usually isolated from hospital effluents, however, no systematic study on the distribution of phages in hospital effluents has been conducted so far. The aim of this study was to isolate the corresponding phages of common pathogenic bacteria isolated in the clinic as hosts, so as to assess the ecological distribution of phages in hospital wastewater and to provide a reference for the isolation and application of phages of drug-resistant bacteria in the clinic. A cross-sectional study design was used in this study. The 125 pathogenic bacteria (belonging to 16 different strains) isolated from the clinical microbiology laboratory of Qilu Hospital of Shandong University from May to June 2023 were selected as the target strains, and the phages corresponding to these strains were isolated and purified from the hospital wastewater by using the double-layer plate sandwich method. At the same time, the distribution of pathogenic bacteria in the same batch of wastewater was analyzed with the help of mNGS sequencing technology, so as to preliminarily investigate the abundance correspondence between pathogenic bacteria and phages in wastewater. The results showed that a total of 56 phage strains were isolated from 125 clinical pathogens as hosts, corresponding to six pathogens, including Acinetobacter baumannii, Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Stenotrophomonas maltophilia. All six pathogenic bacteria contained strains with different degrees of drug resistance, with a higher percentage of multi-drug resistant strains in A. baumannii, Escherichia coli and P. aeruginosa. The phage acquisition rates of these six pathogens were, in descending order, Escherichia coli (80%), Stenotrophomonas maltophilia (75%), Pseudomonas aeruginosa (70%), Klebsiella pneumoniae (66.67%), Acinetobacter baumannii (36.36%) and Staphylococcus aureus (12.5%). Preliminary mNGS sequencing results showed that the pathogenic bacteria with higher abundance in the batch of effluent were Enterococcus faecalis, Klebsiella pneumoniae, Escherichia coli, Enterococcus faecalis, Acinetobacter baumannii, Klebsiella aerogenes, Klebsiella michiganensis and Pseudomonas aeruginosa. In conclusion, phages of most common clinical Gram-negative pathogens were isolated from hospital wastewater with high isolation rates; however, phages of Gram-positive pathogens were isolated at lower rates, and only phages corresponding to Staphylococcus aureus were isolated in this study. The corresponding mNGS sequencing results showed that the distribution of Gram-negative pathogens in sewage may had a positive correlation with the ecological distribution of phages.

Abstract
Thromboembolism is a crucial part of the global disease burden. It has high incidence, high mortality and disability rates, and the mechanism of occurrence and development is extremely complex. It is difficult to detect the disease in the early stage so that we have trouble with clinical prevention and treatment in general. At present, four items of blood coagulation and D-dimer have been widely used in the evaluation and auxiliary diagnosis of thromboembolism, the monitoring of effect for antithrombotic drugs and other fields. The thrombus biomarkers including thrombin-antithrombin complex (TAT), thrombomodulin (TM), tissue plasminogen activator-inhibitor complex (t-PAIC) and α2-plasmin inhibitor-plasmin complex (PIC) fill the gap of laboratory diagnosis before clinical symptoms appear in some degree. This article aims to explain the current application status of TAT, TM, t-PAIC and PIC in thromboembolism and explore their potential application value, so as to provide a reference for selecting appropriate early monitoring indicators for high-risk population of thromboembolism.

Abstract
Sweet sorghum silage (SS; Sorghum dochna 'Dochna') has been extensively studied in recent years as a supplementary forage-to-corn silage (CS; Zea mays L.), but there are still relatively few studies on its effects on the rumen environment of sheep. Determining the short-term impact of converting roughage from corn straws to SS compared to CS on rumen fermentation and bacterial population dynamics was the main goal of the current study. Twelve female thin-tailed Han sheep (29.8 ± 1.34 kg) were randomly divided into one of two treatments: concentrate supplemented with SS or CS, respectively. During the 15-day pretest period, concentrate was fed in two separate feedings at 0800 h and 1800 h, and ensure that the animals were all consumed within an hour of being fed. Thereafter, the animals had free access to corn straw. The feeding procedures during the pretest period were the same as during the measurement period. Rumen fluid was collected via sheep esophageal tube on the last day of adaptation phase (1-7 days) and stabilisation phase (8-30 days), respectively. The results showed that there was a similarity in the total concentration of VFA (volatile fatty acid) and the proportions of acetate, propionate, butyrate, and branched-chain VFA (P > 0.05) and microbial diversity indices (P > 0.05) between the two silage groups throughout the experimental period. The concentration of Ammonia nitrogen (P = 0.001) and proportion of valerate (P = 0.028) decreased in the CS and SS groups, respectively. The abundance and predicted function of rumen bacteria in the SS group did not differ significantly (P > 0.05) between the two measurement phases. However, the abundance of Prevotella_1 (P = 0.038) was higher in the CS group than in the SS group at 7 d. The abundances of Firmicutes (P = 0.005) and Ruminococcaceae_NK4A214_group (P = 0.002) increased, while the abundances of Bacteroidetes (P = 0.044), Proteobacteria (P = 0.046), and Prevotella_1 (P = 0.009) decreased in the CS group at 30 d. Genes related to pyruvate metabolism (P = 0.020) were significantly higher at 30 d than at 7 d, whereas purine metabolism (P = 0.007), pyrimidine metabolism (P = 0.007), and metabolic pathways (P = 0.010) were lower at 30 d in the CS group. In conclusion, this study indicated that SS maintained a steady rumen environment, while CS caused high fluctuations in bacterial abundance and predicted function for sheep.

Abstract
OBJECTIVES This study aimed to compare the time required and concerns raised by various perspectives of participants regarding administering subcutaneous and intravenous trastuzumab for patients with breast cancer (BC). DESIGN This observational time-motion study design with mixed-methods research (cross-sectional surveys and semistructured interviews) was conducted. The time spent on preparing or administering trastuzumab by different healthcare professionals (HCPs) was recorded. The data were analysed by descriptive/inferential statistical analyses, followed by thematic analyses. SETTING Outpatient and inpatient administration units of a single medical centre in Taiwan. PARTICIPANTS The study included patients with early-stage BC who received subcutaneous or intravenous trastuzumab (n=93), and HCPs including two attending physicians, a nurse practitioner, two pharmacists and two nurses. RESULT Based on the perspectives of patients and HCPs, the subcutaneous form of trastuzumab was more efficient, less expensive and produced less discomfort in outpatient units than inpatient units. More participants preferred the subcutaneous form over the intravenous form in both outpatient and inpatient units. Pharmacists and nurse practitioners spent threefold more time on patients when preparing and administering the intravenous form in both outpatient and inpatient units. The concerns raised by patients and HCPs varied in certain aspects, including the injection skills, speed, mental distress (eg, needle phobia) and pain associated with the subcutaneous form. Almost all patients preferred receiving the subcutaneous form in outpatient units after the initial COVID-19 outbreak. CONCLUSION Patients with early-stage BC preferred receiving subcutaneous trastuzumab in outpatient units rather than inpatient units or the intravenous form before and after the COVID-19 outbreak. Such findings may serve as real-world evidence to facilitate better quality of care regarding administration of subcutaneous or intravenous trastuzumab in medical settings, and its feasible resolutions to balance the quality, concerns and efficiency of anticancer administration during the COVID-19 pandemic.

Abstract
Abstract
Background: Imlunestrant is a novel, orally bioavailable selective estrogen receptor degrader (SERD) with pure antagonistic properties that result in sustained inhibition of estrogen receptor (ER)-dependent gene transcription and cell growth. Preclinically, imlunestrant has favorable efficacy and pharmacokinetic (PK) properties, including antitumor activity in ESR1-mutant models, along with enhanced efficacy when combined with abemaciclib. In dose escalation (Phase 1a) and dose expansion (Phase 1b) in the EMBER study, imlunestrant monotherapy was well tolerated with favorable safety, PK and encouraging antitumor activity in heavily pre-treated ER+, HER2- advanced breast cancer (aBC) patients (Jhaveri, ASCO 2022); imlunestrant recommended phase 2 dose (RP2D) was determined as 400mg QD. Here, we present the phase 1b dose expansion of imlunestrant with abemaciclib ± aromatase inhibitor (AI) in EMBER (NCT04188548).
Methods: Phase 1b enrolled patients with ER-positive (ER+), HER2-negative (HER2-) aBC [shown prior endocrine therapy (ET) sensitivity or untreated de novo aBC; ≤1 prior therapies for aBC but must not have received a prior CDK4/6 inhibitor]. Patients were randomized, based on menopausal status and presence of visceral metastases, to receive imlunestrant + abemaciclib OR imlunestrant + abemaciclib + AI. Men and premenopausal women received a concomitant GnRH agonist. Serial plasma samples were obtained for PK and ctDNA analysis. Key endpoints included safety and tolerability, PK, objective response rate (ORR) per RECIST v1.1 (ORR: complete response [CR] or partial response [PR]) in patients with measurable disease), and clinical benefit rate (CBR: CR or PR, or stable disease ≥24 weeks) in patients enrolled ≥24 weeks prior to data cut.
Results: As of 26 May 2022, 85 patients have received imlunestrant [n=80 at 400 mg (RP2D); n=5 at 800 mg] in combination with abemaciclib (150mg twice daily) ± AI. Forty-eight (56%) patients had visceral disease and 9% had at least 1 ESR1 mutation detected in ctDNA at baseline. Patients were predominantly (75%) ET pre-treated, 51% with an AI; and 8% and 5%, respectively, had received prior chemotherapy or fulvestrant, for aBC. The most common treatment-emergent adverse events were diarrhea (87%), nausea (58%), fatigue (45%), neutropenia (39%) and abdominal pain (34%). The majority of treatment-related AEs (TRAEs) were Grade 1 or 2, with Grade ≥3 TRAEs occurring in 36% of patients. Most common TRAEs at RP2D (400mg) were diarrhea (81%), nausea (45%), fatigue (33%) and neutropenia (35%). No patient discontinued treatment due to an AE. Dose reductions were required of both imlunestrant and abemaciclib in 6 (7%) patients and of either imlunestrant in 3 (4%) or abemaciclib in 22 (26%) patients. Preliminary efficacy is presented in Table 1.
Conclusion: Imlunestrant in combination with abemaciclib ± AI showed acceptable safety and tolerability, comparable to the MONARCH 2 trial of fulvestrant + abemaciclib, along with evidence of clinical activity in ER+, HER2- aBC patients. These data suggest no additive toxicity of imlunestrant when administered in combination with abemaciclib, along with comparable clinical benefit to that observed in MONARCH 2. Further data will be presented at the meeting. The phase 3, EMBER-3 study is ongoing; evaluating imlunestrant, investigator’s choice ET, and imlunestrant + abemaciclib in ET pre-treated ER+, HER2- aBC patients (NCT04975308).

Abstract
Abstract
BACKGROUND In the Phase II NeoSphere study (NCT00545688), dual HER2 blockade with pertuzumab (P) + trastuzumab (H), + docetaxel (D) significantly increased pathologic complete response (pCR) vs. H+D in the neoadjuvant setting for HER2-positive early breast cancer (EBC), locally advanced (LA) BC, or inflammatory BC, with supportive progression- and disease-free survival (DFS) data. Consistently, the randomized, multicenter, double-blind, placebo (Pla)-controlled Phase III PEONY trial (NCT02586025) significantly improved total pCR (tpCR; primary endpoint) with P+H+D vs. H+D in an Asian population, and safety data were in-line with the known P safety profile. We present the final analysis of long-term efficacy (at 3 and 5 years) and safety from the study.
METHODS Patients had centrally confirmed HER2-positive EBC (T2–3, N0–1) or LABC (T2–3, N2 or N3; T4, any N) and were randomized 2:1 to four neoadjuvant P+H+D or Pla+H+D cycles every 3 weeks. P: 840 mg loading/420 mg maintenance doses (or Pla); H: 8 mg/kg loading/6 mg/kg maintenance; D: 75 mg/m2. Patients then received three fluorouracil, epirubicin, and cyclophosphamide cycles, followed by 13 of P+H or Pla+H in the adjuvant setting for up to 1 year. Long-term outcomes (event-free survival [EFS], DFS, overall survival [OS]; all secondary endpoints) were assessed by Kaplan–Meier methods, Cox proportional hazards models, and a two-sided log-rank test (stratified by disease category and hormone receptor status).
RESULTS Data cut-off was Mar 14, 2022, and 329 patients were randomized; 219 to P; 110, to Pla. Safety populations were 218 and 110 patients, respectively. Baseline characteristics were well balanced. Most patients received the full HER2-targeted cycles. Median follow-up was 62.9 months. Long-term efficacy data are shown in the table.
During the overall treatment period, 70.6% of patients in the P+H+D arm and 68.2% in the Pla+H+D arm experienced grade ≥3 adverse events (AEs); the most common (in ≥5% of patients in either arm) being neutropenia (59.2% vs. 55.5%), leukopenia (34.4% vs. 34.5%), and febrile neutropenia (5.0% vs. 3.6%). Of the most common any-grade AEs (in ≥30% of patients in either arm), diarrhea was more common in the P+H+D arm (40.8% vs. 17.3% in the Pla+H+D arm). Serious AEs were reported in 17.0% and 13.6% of patients, respectively. No primary cardiac events (heart failure [New York Heart Association grade III or IV] or significant decline of left ventricular ejection fraction) or secondary cardiac events occurred during any study periods.
CONCLUSIONS Long-term efficacy endpoints (EFS, DFS, and OS) were supportive of the primary endpoint results (tpCR) and suggested a clinically meaningful improvement with P+H vs. Pla+H when administered before and after surgery for one year of anti-HER2- therapy. Safety data were in-line with the known P safety profile and generally comparable between arms, with the exception of diarrhea.
PEONY adds to the totality of data showing the benefit of the P+H+D regimen in HER2-positive EBC.

Abstract
BACKGROUND This study aimed to examine the effectiveness and safety of eribulin used as an early-line (EL, i.e., first-/second-line) versus late-line (LL, i.e., third-line and beyond) chemotherapy for recurrent advanced or metastatic breast cancer (A/MBC) patients. METHODS This study conducted a retrospective observation of A/MBC patients initiating eribulin between January 1, 2015, and June 30, 2019, using medical database at a university-affiliated teaching hospital in Taiwan. Patients were assigned into either the EL or LL group based on the timing of respective eribulin treatments and were observed for at least 6 months up to December 2019 for progression-free survival (PFS), time to treatment failure (TTF), overall survival (OS), disease response, and occurrence of adverse events. The Kaplan-Meier and Cox proportional hazard regression survival analyses were performed. RESULTS Of 127 patients, 23.6% (n = 30) and 76.4% (n = 97) were assigned to the EL and LL groups, respectively, between which no difference in patient characteristics was noted. Median PFS and TTF were 6.5 months and 5.0 months for the EL and 4.2 months and 3.4 months for the LL, respectively. Median OS could not be estimated in the EL group and was 20.5 months in the LL group. Eribulin as an EL treatment was the only factor associated with longer TTF and OS, whereas the number of metastatic sites was additionally associated with PFS in the multivariate analysis. No complete response was reported in either group, but a partial response was obtained in 6.7% in the EL group and 3.1% in the LL group. The common adverse events between two groups were similar, including leukopenia (80.0%), neutropenia (76.7%), and anemia (60.0%). CONCLUSIONS The eribulin used as an EL of chemotherapy was effective for A/MBC patients with known toxicities in this study, while eribulin as the LL chemotherapy showed consistent results with previous reports.

Abstract
Objective: To analyze the clinical characteristics of vestibular syncope (VS) associated with drop attacks (DA) in delayed endolymphatic hydrops (DEH). Methods: DEH cases with complete data were retrospectively analyzed, including three DEH cases with DA and VS (VS group), and six DEH cases without DA or VS (control group). The clinical profile, the results of neurotological examinations [such as pure tone audiometry, electrocochleography (EcochG), caloric test, vestibular evoked myogenic potentials (VEMP), and video head impulse test (vHIT)] and treatment outcomes were analyzed. Results: (1) In the VS group, there were three cases of ipsilateral DEH; in the control group, there were six cases of ipsilateral type. One case in each group had a history of migraine. (2) The prevalence of abnormal results in caloric test, vHIT, cervical VEMP, and ocular VEMP in the VS group was 3/3, 1/3, 2/2, and 2/2, respectively, and in the control group was 3/6, 0/3, 1/6, and 4/6, respectively. Two cases in each group underwent EcochG, and no identifiable waveform was elicited on the affected side, and-SP/AP ratio of unaffected side was less than 0.4. (3) Patients in both groups were initially treated with conservative medication. Two cases in the VS group subsequently received intratympanic injections of dexamethasone. No DA or VS occurred during a follow-up period lasting over one year. All patients achieved good control of vertigo during the follow-up period. Conclusions: VS may occur in the patients with DEH. The differential diagnosis of syncope in patients with otogenic vertiginous disease can help improve clinical diagnosis and treatment.

Abstract
Abstract
Study question
Is cervical secretion gene methylation profile different between receptive and non-receptive endometrium and associated with implantation outcome in frozen-embryo transfer (FET) cycle?
Summary answer
The combination of candidate genes methylation profiles obtained from cervical secretion showed significant associations with pregnancy outcomes.
What is known already
Implantation failure remains a black box in reproductive medicine, and the exact mechanism of how endometrial receptivity is regulated is still unknown. Epigenetic modifications play a role in the gene expression pattern and may alter the endometrial receptivity in the human endometrium. Cervical secretion containing various implantation-related cytokines, and the gene methylation change can be used as a non-invasive molecular source that reflects the endometrium condition.
Study design, size, duration
In this retrospective case-control study, sixty-two women who entered the FET cycle (30 pregnant and 32 non-pregnant women) were enrolled.
Participants/materials, setting, methods
Cervical secretion was collected before embryo transfer from women enrolled in multicenter university-affiliated reproductive units. The DNA methylation status of six candidate genes was measured using quantitative methylation-specific PCR (qMSP). The correlation between methylation change and the pregnancy outcome was analyzed.
Main results and the role of chance
The candidate genes were selected from that associated with implantation with literature review and the original genome-wide DNA methylation data from NCBI GEO DataSets (GSE90060) which processed using bioinformatics analysis. Six candidate genes whose CpG-level methylation analysis with β-value statistically higher in receptive endometrium than in a pre-receptive endometrium were selected. All six candidate genes showed different degrees of correlation with the pregnancy outcomes. Among them, PRKAG2 methylation changes showed the highest correlation with the pregnancy outcome. A logistic regression model was used to evaluate the performance of a single gene or a combination of genes for implantation prediction. The results showed a statistically significant association between the methylation status of a combination of genes (PRKAG2, KRS1, HAND2) and the pregnancy outcome (p = 0.008), resulting in an optimal AUC of 0.7 (95% CI: 0.57 - 0.81) for implantation prediction.
Limitations, reasons for caution
The results obtained from a relatively small cohort size. A larger study and further comprehensive methylome investigations are warranted.
Wider implications of the findings: This study is the first proof-of-concept study that cervical secretion methylation profile is associated with implantation outcome in a FET cycle, and showed potential as a non-invasive method for implantation prediction.

Abstract
BACKGROUND/AIM Triple negative breast cancer (TNBC) is characterized by increased recurrence and poor survival. Mounting evidence suggests that interleukin-10 (IL-10) plays a role in carcinogenesis, however, little is known about the contribution of IL-10 to TNBC. The study evaluated the contribution of IL-10 promoter A-1082G (rs1800896), T-819C (rs3021097), A-592C (rs1800872) genotypes to the risk of TNBC. MATERIALS AND METHODS IL-10 genotypes were examined among 1,232 breast cancer patients and 1,232 controls and evaluated. RESULTS The percentages of AG and GG for IL-10 A-1082G genotypes were higher in the breast cancer patient group than in the control group. The GG genotype carriers were of higher risk for breast cancer [odds ratio (OR)=2.02, 95% confidence interval (CI)=1.28-3.21, p=0.0021]. Interestingly, G allele carriers were of higher risk of TNBC (OR=1.25, 95%CI=1.07-1.46, p=0.0050). CONCLUSION The G allele of IL-10 A-1082G genotype may serve as a predictor for TNBC risk. The finding should be validated in other populations.

Abstract
BACKGROUND/AIM The current study aimed at evaluating the contribution of IL-13 promoter rs1881457 and rs1800925 genotypes to the risk of breast cancer in Taiwan. MATERIALS AND METHODS A total of 1,232 breast cancer cases and 1,232 age-matched controls were genotyped by typical polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodology. RESULTS As for IL-13 rs1881457, the rates of AA, AC and CC genotypes were 54.8, 37.9 and 7.3% among the cases, and 53.8, 38.7 and 7.5% among the healthy controls, respectively; there were no statistically significant differences between the two groups (p for trend=0.8889). Also, regarding IL-13 rs1800925, there were no statistically significant differences between the two groups either (p for trend=0.6803). Furthermore, the allelic frequencies for IL-13 rs1881457 and rs1800925 were not differentially distributed between the case and control groups (p=0.6515 and 0.8753, respectively). CONCLUSION The rs1881457 and rs1800925 IL-13 promoter polymorphisms may not serve as breast cancer susceptibility determinants for Taiwanese.

Abstract
AIM To analyse the effects of the alternatively spliced fibronectin (FN) gene and its isoforms on osteoclastogenesis in radicular cysts. METHODOLOGY Specimens of radicular cysts were collected surgically from 22 patients whose radiolucent periapical areas were measured on digital panoramic radiographs before surgery. The associations between the radiolucent areas and FN isoforms, vascular endothelial growth factor (VEGF) expression or micro-vessel density, as well as the relationships amongst them, were analysed by immunohistochemical staining using the antibodies IST-9, BC-1, P1F11, VEGF and CD34. Fibroblasts isolated from those specimens were used to induce Trap + MNCs, and the effects of induction were assessed by blocking FN containing extra domain A (EDA + FN), COX-2 or VEGF in vitro. The effects of EDA exon knockout using CRISPR/Cas system were also assessed. Quantitative PCR was used to analyse relative expression of FN isoforms and osteoclastogenic genes. Data were analysed using linear regression, Spearman's rank correlation analysis, chi-square test and Student's t-test; P < 0.05 was considered significant. RESULTS Micro-vessel density and EDA + FN staining were positively associated with the size of radiolucent periapical areas (mm2 ; P < 0.05), consistent with a positive association between Trap + MNCs and VEGF expression in fibroblasts (P < 0.05). Blocking the interaction between EDA + FN and fibroblasts inhibited Trap + MNC formation. In addition, EDA exon knockout decreased VEGF expression and inhibited Trap + MNC formation to the extent of blocking VEGF by bevacizumab, but osteoclastogenic induction was restored by recombinant VEGF. Using retrospective clinicopathological data, VEGF staining was shown to be positively associated with EDA + FN staining, micro-vessel density and the size of radiolucent areas (P < 0.05). CONCLUSION In fibrous capsules of radicular cysts, the alternatively spliced isoform EDA + FN generated by fibroblasts stimulated VEGF expression via an autocrine effect and then facilitated osteoclastogenesis. Both blockage of VEGF and EDA exon knockout could be used to inhibit bone destruction.

Abstract
Graphene derivatives are the new bioactive material with good physical and chemical properties and excellent biocompatibility. It has been found that graphene derivatives can improve the mechanical properties of biomaterials and promote the adhesion, proliferation and differentiation of osteoblast-related cells, so as to promote implant-bone bonding and repair of bone defects. This makes it a research hotpot in the field of bone tissue regeneration. In this paper, the mechanism of graphene derivatives promoting bone regeneration and their application in the oral field were reviewed, so as to provide theoretical basis for their application in basic and clinical research.

Abstract
BACKGROUND/AIM The family of matrix metalloproteinases (MMPs) are responsible for the homeostasis of extracellular matrix components and their genetic polymorphisms may be associated with cancer susceptibility. The serum levels of MMP-1 have been reported to be lower in breast cancer patients than healthy subjects. In the current study, we aimed at investigating the contribution of a polymorphism in the promoter region of MMP-1 to breast cancer in Taiwan. MATERIALS AND METHODS The MMP-1 rs1799705 polymorphic genotypes were genotyped among 1,232 breast cancer patients and 1,232 healthy controls by the typical polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The percentages of 2G/2G, 1G/2G, and 1G/1G for MMP1 -1607 genotypes were 35.4, 40.6 and 24.0% in the breast cancer group and 34.1, 43.6, and 22.3% in the healthy control group (p trend=0.3025), respectively. The odds ratios (ORs) after adjusting for age, smoking and alcohol drinking status for those carrying 1G/2G and 1G/1G genotypes at MMP1 -1607 were 0.93 (95%CI=0.76-1.11, p=0.2390) and 1.01 (95%CI=0.77-1.23, p=0.7377), respectively, compared to those carrying the wild-type 2G/2G genotype. Supporting this finding, the adjusted OR for those carrying the 1G allele at MMP-1 -1607 was 1.03 (95%CI=0.91-1.18, p=0.8860), compared to those carrying the wild-type 2G allele. Our findings suggest that the polymorphic genotypes at MMP1 promoter -1607 investigated in the current study, may not play a major role in determining cancer susceptibility to breast cancer in Taiwan. Other early diagnostic and predictive markers are urgently needed for personalized and precise breast cancer detection and therapy.

Abstract
Compared with other subgroups of breast cancer, triple negative breast cancer (TNBC) is considered to be the one with the greatest invasiveness and metastatic mobility, and the highest recurrence rate. Considering the lack of predictive markers for TNBC, we aimed to examine the contribution of excision repair cross complementing-group 1 (ERCC1) genotypes to TNBC. The rs11615 and rs3212986 of ERCC1 were investigated and evaluated for their associations with susceptibility to breast cancer, especially TNBC, in Taiwan. In this study, 1,232 breast cancer patients (104 were TNBC) and 1,232 healthy controls were recruited and their genotypes at ERCC1 rs11615 and rs3212986 were revealed by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) analysis. Our results indicated that genotypes of ERCC1 rs11615 (Ptrend = 2.2*10E-9), but not rs3212986 (Ptrend = 0.6181), were associated with breast cancer risk. In the allelic frequency distribution analysis, breast cancer patients carried the T allele of ERCC1 rs11615 a higher rate than the control subjects, further supporting the idea that ERCC1 rs11615 TT genotype is positively associated with breast cancer susceptibility. More importantly, the frequency of the ERCC1 rs11615 TT genotype was even higher among TNBC patients than among other subtypes of breast cancer patients (P = 0.0001, odds ratio = 1.73, 95% confidence interval = 1.15-2.63). The genotypes of ERCC1 rs11615 were not associated with Ki67 status. Our findings firstly show that the T allele of ERCC1 rs11615 can serve as a predictive biomarker for breast cancer and TNBC. We believe that ERCC1 could serve as a target for personalized treatment of breast cancer, especially for TNBC.

Abstract
BACKGROUND/AIM The family of matrix metalloproteinases (MMPs) controls homeostasis of the extracellular matrix and their genetic polymorphisms may be associated with personal cancer susceptibility. The serum levels of MMP8 was reported to be higher in patients with breast cancer than in healthy individuals. In this study, we aimed to investigate the contribution of a polymorphism in the promoter region of MMP8 (-799C/T) and two nonsynonymous polymorphisms (Val436Ala and Lys460Thr) to breast cancer. MATERIALS AND METHODS MMP8 -799C/T, Val436Ala and Lys460Thr polymorphic genotypes were determined for 1,232 patients with breast cancer and 1,232 healthy controls by polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The odds ratios (ORs) after adjusting for age, gender, smoking and alcohol drinking status for those carrying CT and TT genotypes at the MMP8 promoter C-799T were 1.03 (95% CI=0.88-1.23, p=0.7475) and 1.08 (95% CI=0.91-1.53, p=0.3561), respectively, compared to those carrying the wild-type CC genotype. The OR for the combined T-bearing genotypes were of a similar non-significant level (OR=1.05, 95% CI=0.90-1.26, p=0.5176). Supporting this finding, the adjusted OR for those carrying the T allele at MMP8 C-799T was 1.05 (95% CI=0.86-1.21, p=0.3797), compared to those carrying the wild-type C allele. There was also no significant association of MMP8 Lys460Thr with breast cancer. There was no polymorphic genotype at MMP8 Val436Ala found among any of the investigated individuals. CONCLUSION MMP8 -799C/T, Val436Ala and Lys460Thr polymorphisms may only play an indirect role in determining personal cancer susceptibility to breast cancer in Taiwan.

Abstract
This study aimed to determine if short-term nutrient alteration affects (1) ovarian morphology, (2) plasma and ovarian antioxidant capability and (3) cell apoptosis and AKT signaling within the ovary. After estrus synchronization, 24 Hu sheep were assigned to three groups based on the nutrient requirement recommended for maintenance (M): 1 × M (Control), 1.5 × M (S) and 0.5 × M (R) during days 7–14 of their estrous cycle. The results indicated that undernourishment significantly increased the counts and volume of follicles <2.5 mm and decreased the counts and volume of follicles ≥2.5 mm (P < 0.05). Feed restriction altered the plasma and follicular redox balance within follicles ≥2.5 mm by inhibiting total antioxidant capacity, increasing malondialdehyde concentration (P < 0.05) and reducing the mRNA expression levels of superoxide dismutase 2 (SOD2) and glutathione peroxidase (GSH-PX), as well as the activities of total SOD and GSH-PX. Feed restriction also attenuated B-cell lymphoma-2 (BCL2) but enhanced Bcl-2-associated X protein (BAX) andBAX/BCL2transcription and translation levels in granulosa cells (P < 0.05). Uniform staining intensities of AKT and P-AKT-Ser473 were observed in each follicle stage, whereas weaker P-AKT-Thr308 staining in the antral follicle than in the pre-antral follicle suggested possible involvement of P-AKT-Thr308 during the beginning of follicle development. P-AKT-Ser473 levels in follicles ≥2.5 mm was significantly reduced in the R group (P < 0.05). The results presented in this study demonstrate that suppressed folliculogenesis caused by feed restriction might be associated with attenuated AKT signaling, reduced follicular antioxidant capacity and enhanced granulosa cells apoptosis.

Abstract
BACKGROUND/AIM The matrix metalloproteinase (MMP) family of enzymes are in charge of degradation of various components of the extracellular matrix and their functional genetic polymorphisms may be associated with cancer susceptibility. The functional polymorphisms in the promoter region of MMP7 (A-181G and C-153T) have been reported to influence the binding capacity of nuclear proteins and may contribute to genetic susceptibility to cancer. In this study, we focused on investigating the contribution of the genotypes of MMP7 (A-181G and C-153T) to breast cancer in Taiwan. MATERIALS AND METHODS These two polymorphisms were genotyped in 1,232 patients with breast cancer and 1,232 controls by polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The odds ratios (ORs) after adjusting for age, family history of cancer, smoking and alcohol drinking status for those carrying AG and GG genotypes at MMP7 promoter A-181G were 1.22 (95%CI=0.91-1.63, p=0.2235) and 2.84 (95%CI=1.64-7.48, p=0.0007) respectively, compared to those carrying the wild-type AA genotype. Supporting this finding, the adjusted OR for those carrying the G allele at MMP7 promoter A-181G was 1.57 (95%CI=1.29-1.93, p=0.0008), compared to those carrying the wild-type A allele. There was no polymorphic genotype at MMP7 C-153T found among any of the investigated individuals. CONCLUSION Our findings suggest that the MMP7 A-181G polymorphisms may play a role in determining personal cancer susceptibility and GG genotype at MMP7 A-181G may serve as a biomarker for early detection and prediction of breast cancer in Taiwanese.

Abstract
AIM PEGylated liposomal doxorubicin (PLD) has comparable efficacy and differing toxicity from conventional anthracyclines used to treat advanced breast cancer. This study compared disease-free survival and toxicity between PLD-based and conventional anthracycline-based regimens as adjuvant treatments for early-stage breast cancer. METHODS We analyzed disease-free survival (DFS) rates, and adverse events in 102 women with early-stage (I-IIIa) breast cancer who received adjuvant PLD-based chemotherapy from 2002 to 2008. Each patient was matched for age, stage at diagnosis, HER-2 expression and hormone therapy use to a patient treated with an epirubicin-based regimen. Fisher's exact and Pearson's chi-square tests were used for categorical data analysis. Kaplan-Meier analysis and Cox regression models were used to analyze DFS. RESULTS DFS at 5 years was 81.3% for PLD-based regimen and 82.3% for epirubicin-based regimen. This difference was not significant (p = 0.939). Stage IIIa disease was associated with a shorter DFS in univariate analysis (p = 0.048). In multivariate analysis that controlled for adjuvant treatment, age at diagnosis, stage, HER-2 expression, type of surgery and hormone and radiation therapy, stage IIIa disease (P = 0.023) and lack of hormone therapy (P = 0.024) were each independently associated with shorter DFS. Adverse events were evaluated, and with the exception of hand-foot syndrome, more grade 3 and 4 toxicities occurred in patients who received epirubicin-based regimens than in those given PLD-based regimens. CONCLUSION For patients with early-stage breast cancer who received PLD-based adjuvant chemotherapy, 5-year DFS was comparable and toxicity was acceptable, yet different from those of patients who received epirubicin-based regimens.

Abstract
Nonlinear effects of photo-induced waveguides based on isomerization photochemistry are investigated. It is found that polarization information of the controlling light can be used to control the propagation of the signal light in all-optical waveguides, and an accurate and convenient light-controlling-light scheme is proposed, that is, controlling propagation of the signal light by synergic use of the intensity information and polarization information of the controlling light. The polarization dependence of optical nonlinearity is expected to enrich the connotation of the optical nonlinear effects and has theoretical significance and practical value.

Abstract
The gastrointestinal lumen can directly absorb all di- and tripeptide protein degradation products, and oligopeptide absorption depends on the specific peptide transport carriers, which are located in gastrointestinal epithelial cells on the brush border membrane. Yak () use N more efficiently than cattle do, which implies that yak have a specific mechanism of nonprotein utilization including a peptide absorption mechanism. However, this mechanism has not been clarified. Our objective was to explore whether yak possess any adaptive mechanisms of peptide absorption to survive in the harsh foraging environment of the Qinghai-Tibetan plateau. Twelve castrated males of each of 2 genotypes, yak () and indigenous cattle (), were fed diets of various N levels. The yak PepT1 (yPepT1) cDNA was cloned in omasum epithelial tissue. Our results showed that the full-length yPepT1 cDNA contains 2,805 bp, and a 2,121-bp open reading frame encodes a putative protein of 707 AA residues. The yPepT1 AA sequence identified 5 putative extracellular N-glycosylation sites (Asn, Asn, Asn, Asn, and Asn), 2 putative intracellular protein kinase A sites (Ser and Thr), and 3 intracellular putative protein kinase C sites (Ser, Ser, and Ser). The yPepT1 AA sequence was 99, 95, 86, and 83% identical to PepT1 from cattle (), sheep (), pigs (), and humans (), respectively. The relative PepT1 mRNA expression for indigenous cattle was greater than yak in the rumen, omasum, duodenum, ileum, and liver ( < 0.001); however, it was lower in jejunum tissue ( < 0.01). The relative PepT1 mRNA expression in response to increasing dietary N for both genotypes were linear in the rumen and jejunum ( < 0.10); quadratic or cubic in the reticulum ( < 0.01); linear or quadratic in the duodenum, ileum, and liver ( ≤ 0.01); and linear, quadratic, or cubic in the omasum ( < 0.001). Moreover, there were significant interactions between genotype and dietary N in rumen, reticulum, omasum, duodenum, jejunum, ileum, and liver tissues. In conclusion, the PepT1 profile and expression in gastrointestinal epithelial cells of yak varied from those of cattle, implying that yak have evolved a peptide transport mechanism to adapt the environment of the Qinghai-Tibetan plateau.

Abstract
Objective: To analyze the epidemic features of dyslipidemia among 39 980 Uygur, Kazak and Han ethnic groups in Urumqi, and to explore the methods of prevention and treatment on dyslipidemia. Methods: The differences of blood total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) of health examination population with different ethnics, genders, and ages were compared, from 2012 to 2014 in the First Affiliated Hospital of Xinjiang Medical University. Results: Among the Uygur, Kazak and Han ethnic groups, the positive rate was respectively 35.0%, 37.0%, 30.3% in TC; 34.5%, 30.1% and 32.0% in TG; 24.9%, 18.3%, and 18.2% in HDL-C; 30.1%, 31.6% and 23.3% in LDL-C. In the same ethnic group, the abnormality rate of blood lipid in the female was lower than that of the male (P<0.001). The blood lipid abnormality rate increased significantly in those with 30-39 years, and reached the highest value in the 50-59 years group, then it decreased in those aged over 60 years (P<0.001). Conclusion: The lipid abnormality rate of the Uygur and Kazak residents was higher than that of the Han nationality, and the abnormal levels of TC and LDL-C were particularly evident in Urumqi.

Abstract
In this paper, we develop a diode-pumped all-solid-state high-energy and high beam quality Nd:YAG laser system. A master oscillator power amplifier structure is used to provide a high pulse energy laser output with a high repetition rate. In order to decrease the amplifier working current so as to reduce the impact of the thermal effect on the beam quality, a beam splitting-amplifying-combining scheme is adopted. The energy extraction efficiency of the laser system is 50.68%. We achieve 3.36 J pulse energy at a 100 Hz repetition rate with a pulse duration of 7.1 ns, a far-field beam spot 1.71 times the diffraction limit, and 1.07% energy stability (RMS).

Abstract
To study metabolic adaptation to harsh foraging conditions, an experiment was conducted to characterize and quantify N utilization efficiency and urea metabolism in Tibetan and fine-wool sheep fed 4 levels of dietary N (11.0, 16.7, 23.1, and 29.2 g N/kg DM) in 2 concurrent 4 × 4 Latin square designs. Urea kinetics were determined using continuous intrajugular infusions of 15N15N-urea. Urinary excretions of total N and urea N increased linearly (P < 0.001) with dietary N and were not different between breeds (P ≥ 0.37). Fecal N excretion increased with dietary N for Tibetan sheep but not for fine-wool sheep (linear dietary N × breed; P < 0.05). Nitrogen retention (both amount per day and percentage of N intake) increased with increasing dietary N concentration (P < 0.001), and the rates of increase were greater in fine-wool than in Tibetan sheep (linear dietary N × breed and cubic dietary N × breed; P < 0.05). In Tibetan sheep, N retention as a percentage of intake was greatest for diets containing 16.7 g N/kg DM, whereas it was maximal for fine-wool sheep when the diet contained 23.1 g N/kg DM. Urea N entry rate, urea N recycled to the gastrointestinal tract (GIT), and urea N returned to the ornithine cycle all increased with dietary N (P < 0.05), and all were greater in Tibetan than fine-wool sheep for the 11.0 g N/kg DM diet but were greater in fine-wool than Tibetan sheep for the diet with 29.2 g N/kg DM (linear dietary N × breed; P < 0.05). Urea N excreted in feces, both amount and fraction of GIT entry rate, was less in Tibetan than fine-wool sheep for the 11.0 and 16.7 g N/kg DM diets but similar for diets with 23.1 or 29.2 g N/kg DM (linear dietary N × breed; P < 0.01). For the lowest-protein diet, the fraction of urea N production recycled to the GIT was greater in the Tibetan than fine-wool sheep (88% vs. 82%), but for the diet with 29.2 g N/kg DM it was greater for fine-wool than Tibetan sheep (46% vs. 39%; linear dietary N × breed; P < 0.05). Plasma urea N increased more rapidly in response to increasing dietary N concentration for fine-wool sheep than for Tibetan sheep (linear dietary N × breed; P < 0.05). Urea tubular load and the amount and percentage of urea reabsorbed by the kidney were greater in Tibetan than fine-wool sheep (P < 0.05). These results suggest that Tibetan sheep have mechanisms that allow them to utilize N more efficiently than the fine-wool sheep when dietary N is inadequate.

Abstract
BACKGROUND Conventional anthracyclines play an essential role for the treatment of breast cancer and have potent cytotoxic activity, but are associated with severe toxicity. In metastatic breast cancer, pegylated liposomal doxorubicin (PLD) is a formulation with efficacy similar to conventional doxorubicin but with reduced toxicity. This multicenter study evaluated the efficacy and safety of PLD-based adjuvant chemotherapy for women with stage I-III operable breast cancer. PATIENTS AND METHODS One hundred and eighty women with stage I-III breast cancer who received PLD-based adjuvant chemotherapy at six different Institutions in Taiwan from February 2002 to March 2008 were included and followed-up until April 2015. Treatment efficacy was determined by disease-free survival (DFS) rate and safety was evaluated by adverse events. RESULTS The 5- and 10-year DFS rates were 76.3 and 72.6%, respectively. Univariate analysis revealed that tumor size >5 cm (p=0.045; hazard ratio=3.31) and stage III (hazard ratio=3.54; p=0.019) were each associated with shorter DFS. Only stage III (hazard ratio=5.60; p=0.018) retained statistical significance with regard to DFS in the multivariate analysis. Grade 3/4 hematological toxicity was neutropenia (n=13; 7.2%). The women receiving PLD had low-grade 3 or 4 nausea/vomiting, mucositis, and alopecia. Grade 3 hand-foot syndrome occurred in three patients (1.7%). CONCLUSION PLD could be considered an effective and safe alternative to conventional anthracyclines in the treatment of stage I-III operable breast cancer.

Abstract
The tissue inhibitors of metalloproteinases (TIMPs) are a family of multifunctional proteins which have been shown to be upregulated in various types of cancers. However, the contribution of TIMPs in breast cancer is not fully understood, not to mention triple negative breast cancer (TNBC). This study’s aim was to evaluate the contribution of TIMP-1 rs4898, rs6609533, and rs2070584 genotypes to the risk of breast cancer, especially the subtype of TNBC. The contributions of these TIMP-1 genotypes to cancer risk were examined among 1232 breast cancer patients and 1232 healthy controls, and several clinicopathologic factors were also analyzed. The results showed that the percentages of CC, CT, and TT of TIMP-1 rs4898 were differentially distributed at 28.5%, 33.1% and 38.4% in the breast cancer patient group and 34.5%, 41.0% and 24.5% in the control group, respectively (P for trend = 7.99*10-13). It was also found that the CC genotype carriers were of increased risk for breast cancer (odds ratio = 1.90, 95% confidence interval = 1.55-2.33, P = 0.0001) than the TT genotype carriers. In addition, we analyzed the allelic frequency distributions of all three TIMP-1s, and the results showed that the C allele of TIMP-1 rs4898 contributes to an increase in breast cancer susceptibility (P = 2.41*10-12). On the other hand, there was no difference found in the distribution of genotypic or allelic frequencies among the patients and the controls for TIMP-1 rs6609533 and rs2070584. Thus, it is our conclusion that the CC genotype of TIMP-1 rs4898 compared to the TT wild-type genotype may increase the risk for breast cancer, especially TNBC in Taiwan, and may serve as an early detective and predictive marker.

Abstract
Despite sharing a similar genetic abnormality, patients with core binding factor acute myeloid leukemia (CBF-AML), which is characterized by the presence of t(8;21) or inv(16)/t(16;16), show heterogeneous survival. Other molecular or cytogenetic factors are supposed to have an impact on the prognosis. We enrolled 24 CBF-AML patients to determine the impact of cytogenetic abnormality, and c-KIT, FLT3, NPM1, and CEBPA mutations on the prognosis. Only three patients had the c-KIT mutation (3/24, 12.5%) and one had the FLT3 mutation. However, over half of the patients (14/24) harbored additional cytogenetic changes, including ten with loss of sexual chromosomes (LOS) [all in the t(8;21) group], and six had additional abnormalities (two cases had both LOS and additional abnormalities). From this small-number study, no association was found between c-KIT mutation and survival and relapse rate. However, additional chromosome abnormalities had a significant association with relapse of the disease (P = 0.027). Stem cell transplant had a trend of benefitting patients after relapse (P = 0.065). This implies that chromosome abnormalities occur in CBF-AML and might take part in the heterogeneous nature of CBF-AML.

Abstract
Growth and meat quality traits play important roles in the evaluation of cattle productivity and are influenced by genetic and environmental factors. CRTC2 is a recently discovered gene related to obesity that may influence fat deposition. The aim of the current study was to detect polymorphisms of bovine CRTC2 and explore their relationships to growth and meat quality in Qinchuan cattle. Three single nucleotide polymorphisms (SNPs); g.3001 C>T; g.3034 G>A; and g.3467 T>C, were identified from sequencing results of 422 Qinchuan cattle. The genotypic distributions of both g.3034 G>A and g.3467 T>C mutations were in agreement with Hardy-Weinberg equilibrium, (P < 0.05), while the T3001C mutation was not (P > 0.05), based on χ(2) test analysis. The SNPs g.3001 C>T and g.3034 G>A are missense mutations (Ser/Phe and Ser/Thr respectively). Additionally, SNPs g.3034 G>A and g.3467 T>C showed a medium polymorphism level (0.25 < PIC< 0.50), whereas g.3001 C>T showed a low polymorphism level (PIC < 0.25). These three SNPs were significantly associated with several growth and meat quality traits in the Qinchuan cattle population (P < 0.05 or P < 0.01). Collectively, these results demonstrate that CRTC2 is involved in the regulation of cattle growth and meat quality, and suggest that CRTC2 is a potential candidate gene for marker-assisted selection in future breeding development programs for Qinchuan cattle.

Abstract
BACKGROUND Monthly goserelin 3.6 mg dosing suppresses estradiol (E2) production and has proven efficacy in pre-menopausal women with estrogen receptor (ER)-positive breast cancer. This non-inferiority study evaluated the efficacy and safety of 3-monthly goserelin 10.8 mg compared with monthly goserelin 3.6 mg. METHODS This was a Phase 3, open-label, multicenter trial. Pre-menopausal women with ER-positive advanced breast cancer were randomized to 3-monthly goserelin 10.8 mg or monthly goserelin 3.6 mg; all patients received concomitant tamoxifen (20 mg daily). The primary endpoint was progression-free survival (PFS) rate at 24 weeks; non-inferiority was to be confirmed if the entire 95 % confidence interval (CI) for the treatment difference was above -17.5 %. Secondary endpoints included objective response rate (ORR), serum E2 levels, safety, and tolerability. RESULTS In total, 222 patients were randomized (goserelin 10.8 mg, n = 109; goserelin 3.6 mg, n = 113). PFS rate at week 24 was 61.5 % (goserelin 10.8 mg) and 60.2 % (goserelin 3.6 mg); treatment difference (95 % CI) was 1.3 % (-11.4, 13.9), confirming non-inferiority of goserelin 10.8 mg compared with goserelin 3.6 mg. ORR was 23.9 % (goserelin 10.8 mg) and 26.9 % (goserelin 3.6 mg); treatment difference (95 % CI) was -3.0 % (-15.5, 9.7). At week 24, mean serum E2 concentrations were similar in the goserelin 10.8 mg and goserelin 3.6 mg groups (20.3 pg/mL and 24.8 pg/mL, respectively). CONCLUSION A regimen of 3-monthly goserelin 10.8 mg demonstrated non-inferiority compared with monthly goserelin 3.6 mg for PFS rate at 24 weeks, with similar pharmacodynamic and safety profiles, in pre-menopausal women with ER-positive breast cancer.

Abstract
The incidence of urinary calculus (UC) is very high in Uyghur children in the Kashi region of Xinjiang, China, which seriously affects the growth and life quality of these children. This study was aimed at investigating the risk factors of UC in Uyghur children in Kashi region. One hundred fifteen Uyghur children (age <7 years) with UC who were treated in First People's Hospital in Kashi were enrolled in the case group. A 1:1 case-control study with a questionnaire was performed. The results showed that, among the 115 UC patients, there were more boys (71.3%) than girls (28.7%), and most cases had an onset age of 1-3 years (75.7%). A lower than primary school education in the mother, drinking unboiled water, water intake <500 mL/day, and eating too much sweets were risk factors [odds ratio (OR) = 2.385, 9.160, 3.263, and 8.945, respectively], whereas vegetable intake and exposure to summer sunshine of <2 h/day were protective factors against UC onset (OR = 0.154 and 0.344, respectively). Analysis of UC-related factors in 99 cases of <3-year-old children revealed that breastfeeding was also a protective factor (OR = 0.007), whereas frequent cow's milk intake within 5 months (OR = 2.414) and frequent "panada" intake (OR = 2.529) were risk factors. The occurrence of UC in Uyghur children in the Kashi region is mainly affected by maternal educational background, quality of drinking water, water intake volume, and dietary pattern. Furthermore, geography may also have a role.

Abstract
Silent information regulator 5 (SIRT5), a member of the Sirtuin family class III nicotinamide adenine dinucleotide-dependent protein deacetylases, plays an important role in metabolic and aging processes in mammals. We identified 4 single-nucleotide polymorphisms (SNPs) (G22010A, G22052A, G22119T, and G22245C) in the 3' untranslated regions of the SIRT5 gene from 572 Qinchuan cattle by sequencing and investigating their association with growth and ultrasound traits. The frequencies of genotype GG and allele G were high at the 4 SNPs. Based on the X(2) test, the genotypic distributions of the 4 SNPs were not in Hardy-Weinberg equilibrium (P < 0.05 or P < 0.01). Association analysis of individual SNPs and haplotype combinations revealed that the 4 loci were significantly associated with some body measurement and ultrasound traits in Qinchuan cattle, and the H1H5 (AG-GA-GG-GG) diplotypes had better performance than other combinations in Qinchuan cattle. Our results demonstrate that SIRT5 may be a candidate for marker-assisted selection in future breeding programs for Qinchuan cattle.

Abstract
In wastewater treatment plants (WWTPs), activated sludge is thickened in secondary settling tanks and recycled into the biological reactor to maintain enough biomass for wastewater treatment. Accurately estimating the activated sludge concentration in the lower portion of the secondary clarifiers is of great importance for evaluating and controlling the sludge recycled ratio, ensuring smooth and efficient operation of the WWTP. By dividing the overall activated sludge-thickening curve into a hindered zone and a compression zone, an empirical model describing activated sludge thickening in the compression zone was obtained by empirical regression. This empirical model was developed through experiments conducted using sludge from five WWTPs, and validated by the measured data from a sixth WWTP, which fit the model well (R² = 0.98, p < 0.001). The model requires application of only one parameter, the sludge volume index (SVI), which is readily incorporated into routine analysis. By combining this model with the conservation of mass equation, an empirical model for compression settling was also developed. Finally, the effects of denitrification and addition of a polymer were also analysed because of their effect on sludge thickening, which can be useful for WWTP operation, e.g., improving wastewater treatment or the proper use of the polymer.

Our objective was to evaluate the efficacy and safety of PLD-based adjuvant chemotherapy compared to conventional chemotherapy for patients with stages I-III Triple-negative breast cancer (TNBC). PATIENTS AND METHODS A total of 162 patients, histologically proven to have TNBC at stages I-III between 2003 and 2010, were enrolled to evaluate the impact of PLD- and non-PLD-based adjuvant chemotherapy by using the end-pint of overall survival (OS) and relapse-free survival (RFS). RESULTS Forty-nine (30.2%) patients received PLD-based adjuvant chemotherapy and 113 (69.8%) a non-PLD regimen, including 84 (52%) patients receiving non-PLD anthracycline. The Kaplan-Meier calculation indicated no differences in RFS and OS between the PLD and non-PLD groups. Multivariate analysis adjusted for tumor size and lymph node status also revealed similar RFS (HR=0.86, 95% CI=0.43-1.73, p=0.678) and OS (HR=0.86, 95% CI=0.41-1.79, p=0.692) for PLD-based chemotherapy compared with non-PLD-based. Patients receiving PLD-based chemotherapy had a relatively lower incidence of grade 3-4 neutropenia (25% vs. 41.6%, respectively; p=0.054) and significantly higher incidence of hand-foot syndrome (16.3% vs. 4.4%, respectively; p=0.010). CONCLUSION PLD-based adjuvant chemotherapy was as effective as conventional chemotherapy for patients with TNBC. PLD is an alternative for patients with TNBC when conventional anthracycline is inappropriate.

Abstract
Primary spontaneous pneumothorax usually occurs as a sporadic event, but may be clustered in certain families with an underlying inherited disorder. Birt-Hogg-Dubι (BHD) syndrome is a rare autosomal dominant disease accounting for familial pneumothorax. BHD syndrome, caused by mutation of the folliculin gene, is characterized by skin fibrofolliculoma, pulmonary cysts, pneumothorax, and renal cancer. We describe a BHD-affected Taiwanese family with clinical and genetic study. A rare mutation of the folliculin gene was detected in the patient and members with pulmonary cysts or pneumothorax, but no skin or renal lesions were found. This mutation was reported in a Taiwanese family and might indicate a pneumothorax-predominant phenotype. Isolated pneumothorax is an uncommon initial presentation of BHD syndrome. Family history should be carefully reviewed when managing a patient with pneumothorax.

Abstract
Overexpression of cyclooxygenase 2 (COX-2) has been suggested to be associated with breast carcinogenesis. The aim of the present study was to evaluate the contribution of genotypic polymorphisms in COX-2 to breast cancer risk of Taiwanese females. In total, 1,232 breast cancer patients and 1,232 healthy controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodology. Six polymorphic variants of COX-2, including G-1195A (rs689466), G-765C (rs20417), T8473C (rs5275), intron 1 (rs2745557), intron 5 (rs16825748) and intron 6 (rs2066826) were examined. The results showed that the GC genotype of COX-2, G-765C was associated with a lower risk compared to the wild-type GG genotype (odds ratio(OR)=0.66, 95% confidence interval(CI)=0.53-0.83, p=0.0005). The C allele of COX-2 G-765C was significantly more frequently found in controls than in cancer patients (p=0.0006). In addition, the OR of the GG/AG+AA, GC/GG and GC/AG+AA at G-765C/Intron 1 combined genotypes compared to wild-type GG/GG genotype were 0.79 (95%CI=0.66-0.96; p=0.0166), 0.61 (95%CI=0.48-0.78; p=0.0001), and 0.71 (95%CI=0.36-1.37; p=0.3040), respectively. As for the combination of G-765C and intron 6, the OR of the GG/AG+AA, GC/GG and GC/AG+AA combined genotypes compared with wild-type GG/GG reference genotype were 0.79 (95%CI=0.62-1.01; p=0.0561), 0.63 (95%CI=0.50-0.81; p=0.0003), and 0.68 (95%CI=0.38-1.21; p=0.1897), respectively. Our results indicate that the C allele of COX-2, G-765C was associated with a decreased risk of breast cancer in Taiwan, and could serve as an early detection and predictive marker for breast cancer risk.

Abstract
BACKGROUND We assessed the effect of zoledronic acid on quality of life (QOL) and pain outcome in breast cancer patients with bone metastases using the European Organization for Research and Treatment of Cancer bone metastases module (EORTC QLQ-BM22). PATIENTS AND METHODS Three hundred sixty-six breast cancer patients receiving zoledronic acid for bone metastases from 13 Centers were prospectively enrolled. QOL was evaluated using the EORTC QLQ-BM22 and pain outcome were measured monthly with a Visual Analog Scale (VAS) score for 24 months. RESULTS No significant change of functional scale (functional interference and psychosocial aspects) of the EORTC QLQ-BM22 was reported. Significant reduction of the symptom scale was noted after treatment compared with the baseline. The painful site subscale was significantly reduced during the first 12 months, with the exception the 6-month follow-up of point. Pain characteristics subscale was also significantly lower from the 2-month time point onwards. VAS scores indicated a significant reduction in pain over the course of the study to the 22-month time point follow-up compared to the baseline. CONCLUSION Zoledronic acid treatment improved QOL of breast cancer patients with bone metastases by relieving bone pain.

Abstract
Aim: Cell cycle regulator cyclin D1 (CCND1) is a pivotal regulator for G1/S phase transition, playing a critical part in initiation of carcinogenesis. Triple negative breast cancer comprises a very heterogeneous group of cancer cells, but little is known about what is wrong in the genome of these patients. This study investigated contribution of CCND1 genotype to individual triple negative breast cancer susceptibility. Materials: In all, 2464 native Taiwan subjects consist of 1232 breast cancer cases and 1232 controls were enrolled in a hospital-based, case-control study. CCND1 A870G (rs9344) genotyping was analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Risk-stratified analyses correlated genotype and age-related characteristics of breast cancer subgroups. Results: No significant difference was found between patient and control groups in distribution of genotypic and allelic frequencies in CCND1 genotype, yet CCND1 A870G (rs9344) GG genotype was far less prevalent in breast cancer patients younger than 55 years (OR=0.62, 95%CI=0.43–0.89, P=0.0362), with first menarche earlier than 12.2 years (OR=0.61, 95% CI=0.42–0.87, P=0.0241), with menopause earlier than 49.0 years (OR=0.57, 95%CI=0.39–0.82, P=0.0093), or showing triple-negative breast cancer (OR=0.28, 95%CI=0.13–0.62, P=0.0006). Such valuable findings suggest CCND1 A870G (rs9344) as a predictive marker for triple negative breast cancer in Taiwanese women; the authors sincerely hope these help us fight the toughest subtype in clinical management.

Abstract
The aim of the present study was to evaluate the effects of the genotypic polymorphisms in methylenetetrahydrofolate reductase (MTHFR) and its interaction with early-onset breast cancer risk in Taiwan. Two well-known polymorphic variants of MTHFR, C677T (rs1801133) and A1298C (rs1801131), were analyzed and their joint effects with individual age- and estrogen-related factors on breast cancer risk were discussed. In total, 1,232 patients with breast cancer and 1,232 healthy controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The MTHFR C677T genotype, but not the A1298C, was differently distributed between cancer and control groups. The T allele of MTHFR C677T was significantly more frequently found in controls than in patients with cancer. In addition, females carrying MTHFR C677T CT or TT genotypes had a higher odds ratio of 1.21 (95% confidence interval=1.03-1.42, p=1.85E-5) for breast cancer, especially before the age of 45.4 years (odds ratio=1.51 and 95% confidence interval=1.20-1.90). Our results indicate that MTHFR C677T T allele was associated with increased risk of breast cancer in Taiwan, especially in cases who were 45.4 old or younger and with earlier menarche age (<12.2 years).

Abstract
Tobacco (Nicotiana tabacum L.) is a leafy, annual, solanaceous plant grown commercially for its leaves. China is the biggest single tobacco market and accounts for more than 40% of the global tobacco consumption (1). Tobacco seed harvested in Guiyang, Guizhou Province, China, are commonly contaminated or infected by various fungal pathogens, which can cause abnormal seedlings with dark brown lesions and stunting of roots and decayed seeds. In 2013, five samples of 500 seeds from tobacco cv. Guiyan 4 were tested for germination on moistened paper on petri dishes. On average, 35% of the seeds from all five samples developed into abnormal seedlings or were decayed and were plated onto potato dextrose agar media and grown for 5 days at 25°C in darkness to confirm the presence of a pathogen. However, one fungus was isolated from an average of 10% of the 500 seeds sampled. It was identified morphologically as Cladosporium cladosporioides (Fresen.) de Vries based on the velvety olive-brown with almost black reverse colony color and dimensions and color of conidia and conidiophores. Conidia formed in long branched chains that readily disarticulate, single celled, elliptical to limoniform, 2 to 8 (avg. 4.3) × 2 to 3 (avg. 2.1) μm. Conidia were pale to olive brown and smooth to verruculose. Ramoconidia were 0 to 1 septate, 7 to 14 (avg. 9.2) × 2 to 4 (avg. 2.6) μm, smooth or sometimes minutely verruculose. Conidiophores were pale to olive brown, macro- and micronemateus, smooth or sometimes verruculose, and of various lengths up to 320 μm long and 2 to 5 μm wide. Primer pair ITS1 and ITS4 was employed to amplify the regions of ITS1-5.8s-ITS2 of the pathogens. Sequences of all three isolates (G3, G10, and G18) (Accession Nos. KF841547, KF841554, and KF841560) were identical to each other and to four sequences in GenBank (JX230994.1, JQ768317.1, JQ768322.1, and AB763555.1). Pathogenicity of the three isolates of C. cladosporioides was verified on tobacco seedlings of 3-week-old grown on wet filter paper in the petri dishes (9 cm in diameter). For each isolate, 20 seedlings incubated in one plate were inoculated with 0.5 ml of a suspension of 105 conidia/ml. Twenty seedlings were treated with sterile water as control treatment. After inoculation, the petri dishes were incubated at 25°C, 100 to 120 μEm-2 S-1, RH > 80%, and 16 h light per day for disease development. At 96 h after inoculation, symptoms comprising medium brown to black lesions on the roots were clearly visible on inoculated plants but not on the control plants. All seedlings inoculated died 9 days after inoculation whereas control seedlings remained symptomless. Re-isolation attempts on PDA from roots demonstrated C. cladosporioides to be present in symptomatic seedlings but not in roots of the control plants. Moreover, the characteristics of the cultured fungi were exactly the same as those originally isolated. Isolates G3, G10, and G18 (KF841547, KF841554, and KF841560) were deposited with the Tobacco Diseased Fungi, Guizhou Academy of Tobacco Sciences, Guizhou, China. Previously, C. cladosporioides has also been isolated from macadamia (Macadamia integrifolia Maiden & Betche) racemes in South Africa (4), from diseased papaya (Carica papaya L.) in Taiwan province of China (2), and from seeds of Amaranthus spp. in Poland (3). To the best of our knowledge, this is the first report of C. cladosporioides causing seed disease on tobacco in China and the disease should be considered in existing disease management practices.

Abstract
BACKGROUND The current study aimed to examine the impact of zoledronic acid therapy on health-related quality of life (HRQoL) in Taiwanese patients with bone metastases from breast cancer. PATIENTS AND METHODS Patients with bone metastases from breast cancer who received zoledronic acid according to the standards of care were enrolled in this observational phase IV study. HRQoL was measured monthly using the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30 (QLQ-C30) and the breast cancer-specific module (BR-23) for 24 months. RESULTS A total of 366 patients from 13 centers were enrolled. QLQ C-30 demonstrated that zoledronic acid improved the HRQoL in different aspects. In particular, a significant reduction of pain in the first 14 months and the 22-month follow-up was reported by patients. QLQ-BR23 indicated improved future perspective and breast symptom scores over the course of the study. CONCLUSION These data confirm the HRQoL benefits and safety of zoledronic acid in Taiwanese patients with bone metastases from breast cancer.
