Abstract
OBJECTIVE The aim of this study was to investigate whether microRNA-577 could inhibit myocardial infarction (MI)-induced cardiomyocyte apoptosis by regulating poly ADP-ribose polymerase 1 (PARP1). MATERIALS AND METHODS MI model was successfully established in mice by ligation of the left anterior descending coronary artery (LAD). The expression levels of microRNA-577 and PARP1 in myocardial tissues of mice were examined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). MI model in cells was established by hypoxia pre-treatment in primary cardiomyocytes and MCM cells. Subsequently, the expression levels of microRNA-577 and PARP1 in hypoxia preconditioning cardiomyocytes were determined as well. Meanwhile, Caspase3 activity in cardiomyocytes overexpressing microRNA-577 or PARP1 was detected using a relative commercial kit. Furthermore, the binding relationship between microRNA-577 and PARP1 was examined by Dual-Luciferase reporter gene assay. RESULTS Infarct size/risk region and risk region/LV in MI group were (62.1±2.2)% and (57.6±1.9)%, respectively. Both of the above two indexes in the MI group were significantly higher than those of the control group. The serum level of LDH in MI mice increased by 2.8-fold when compared with controls. Meanwhile, the expressions of microRNA-577 and PARP1 in myocardial tissues of MI mice were markedly down-regulated in a time-dependent manner. Compared with normoxia preconditioning cardiomyocytes, microRNA-577 expression in hypoxia preconditioning MCM cells and primary cardiomyocytes was remarkably decreased. Dual-Luciferase reporter gene assay confirmed that microRNA-577 could bind to PARP1. After transfection of microRNA-577 mimics, the expression of PARP1 was significantly down-regulated. Moreover, microRNA-577 over-expression inhibited caspase3 expression in hypoxia preconditioning cells, which could be reversed by PARP1 up-regulation. Similarly, microRNA-577 over-expression markedly decreased infarct size, risk region and serum level of LDH in MI mice, which could be reversed by PAPR1 over-expression. CONCLUSIONS MicroRNA-577 inhibits MI-induced cardiomyocyte apoptosis by degrading PARP1.

Abstract
Droplet bouncing on repellent solid surfaces (e.g., the lotus leaf effect) is a common phenomenon that has aroused interest in various fields. However, the scenario of a droplet bouncing off another droplet (either identical or distinct chemical composition) while moving on a solid material (i.e., ricocheting droplets, droplet billiards) is scarcely investigated, despite it having fundamental implications in applications including self-cleaning, fluid transport, and heat and mass transfer. Here, the dynamics of bouncing collisions between liquid droplets are investigated using a friction-free platform that ensures ultrahigh locomotion for a wide range of probing liquids. A general prediction on bouncing droplet-droplet contact time is elucidated and bouncing droplet-droplet collision is demonstrated to be an extreme case of droplet bouncing on surfaces. Moreover, the maximum deformation and contact time are highly dependent on the position where the collision occurs (i.e., head-on or off-center collisions), which can now be predicted using parameters (i.e., effective velocity, effective diameter) through the concept of an effective interaction region. The results have potential applications in fields ranging from microfluidics to repellent coatings.

Abstract
The spin states of magnetic molecules have advantageous attributes as carriers of quantum information. However, spin-vibration coupling in molecules causes a decay of excited spin states and a loss of spin coherence. Here, we detect excitations of spin-vibration states in single nickelocene molecules on Ag(110) with a scanning tunneling microscope. By transferring a nickelocene to the tip, the joint spin-vibration states with an adsorbed nickelocene were measured. Chemical variations in magnetic molecules offer the opportunity to tune spin-vibration coupling for controlling the spin coherence.

Abstract
Abstract
Objective
Clinically significant weight gain of ≥5% from baseline has been commonly reported during chemotherapy treatment for early stage breast cancer and persisting after completion. Based on the known poorer outcomes associated with weight gain after a breast cancer diagnosis, we evaluated differential weight gain by race/ethnicity as a potential explanation for disparities in breast cancer clinical outcomes among racial/ethnic minorities compared to non-Hispanic white women.
Methods
We conducted a retrospective cohort study among women diagnosed with stage I-III breast cancer between 2007 and 2016, who received chemotherapy at Columbia University Medical Center (CUMC) in New York, NY. We extracted data on demographics, clinical characteristics, chemotherapy regimens, and height/weight from the electronic health records. Our main exposure variable of interest was race/ethnicity. The outcome variable was dichotomized as ≥5% weight gain or stable weight (defined as <5% weight gain or loss/≥5% weight loss) from baseline at 3, 6, 12, and 18 months after initiating chemotherapy. We used multinomial logistic regression analyses to determine the association between race/ethnicity and weight gain before and after adjusting for confounders.
Results
Among 789 evaluable women, median age was 55 years (range, 19-92) and the study cohort was racially/ethnically diverse: 39.8% non-Hispanic white, 30.4% Hispanic, 18.0% non-Hispanic black, 10.4% Asian, and 1.4% other. Mean baseline body mass index (BMI) was highest among black women (30.7 kg/m2 ± 7.0), followed by Hispanic (29.4 kg/m2 ± 5.2), non-Hispanic white (27.9 kg/m2 ± 6.9), and Asian (25.5 kg/m2 ± 5.4) women. The proportion of women with ≥5% weight gain increased over time with 13.6% at 3 months, 15.2% at 6 months, 19.0% at 12 months, and 23.6% at 18 months. Compared to non-Hispanic whites, Asian women had a 63% lower odds of ≥5% weight gain (95% Confidence Interval [CI]: 0.15-0.92) at 3 months after initiating chemotherapy. No statistically significant associations were found between other racial/ethnic groups and ≥5% weight gain. Factors associated with weight gain after chemotherapy included younger age at diagnosis, lower baseline BMI, longer duration of chemotherapy, and having Medicaid insurance coverage.
Conclusions
Race/ethnicity was not significantly associated with weight gain after chemotherapy among women with early stage breast cancer. Socioeconomic status (SES) rather than race/ethnicity may be a contributing factor in disparities in weight gain and breast cancer clinical outcomes. Future weight loss programs should target younger, pre-menopausal women and those with lower SES.

Background: Viral infection contributing to systemic lupus erythematosus (SLE) development has been largely reported. However, the SLE risk in patients with human papillomavirus (HPV) infection is unknown. Methods: Data were retrieved from the Longitudinal Health Insurance Database (2000) in Taiwan. We identified 43,567 patients with HPV infection and 174,268 age- and sex-matched uninfected controls from 2002 to 2012. Individuals were followed up from index date (first date of diagnosis with HPV) until the occurrence of SLE, at the end of the study (December 2013), or when they were withdrawn from the insurance program. The incidence rate ratio (IRR) was calculated using the univariate Poisson regression. The adjusted hazard ratios (aHRs) were calculated, and sensitive and subgroups analyses were also conducted. Results: Compared with the non-HPV controls, the IRR of SLE in HPV patients was 1.52 (95% confidence interval (CI): 1.09–2.12). The risk of SLE in HPV-infected individuals was significantly high (aHR: 1.48, 95% CI: 1.06–2.06) after adjusting for age, sex, and comorbidities. Men aged between 16 and 45 years were more susceptible to developing SLE (aHR: 21.57, 95% CI: 2.52–184.60, p = 0.0051). Conclusion: Our study showed a significantly higher risk of SLE among HPV-infected patients, especially in men aged between 16 and 45 years.

Abstract
MXenes are novel 2D transition metal carbides with metallic conductivity and hydrophilic surfaces, which have highly active 2D surfaces and can act as a promising new type of electrode material; however, their low capacity and irreversible self-restacking limit their practicality and development. This paper presents a novel method for preparing an MXene-polyoxometalate (POM) nanohybrid using poly(ionic liquid) (PIL) as the linker. The electrostatic interactions, chemical structure, and morphology of this nanohybrid are systematically characterized and have indicated that the MXene-PIL-POM nanohybrid provides the uniform distribution of POM nanoparticles on the MXene nanosheets and exhibits excellent electrochemical activity and stability due to the use of PIL as the linker and stabilizer. The prepared MXene-PIL-POM nanohybrid, used as an electrode, displayed a definite improvement in electrochemical performance with the specific capacitance of 384.6 F g-1 at a current density of 1 A g-1, which is about three-fold higher than that of the MXene electrode. The MXene-PIL-POM electrode also achieved a good rate performance (90.5% retention at 10 A g-1) and a long cycling life (91.7% maintenance of specific capacitance at a constant current density of 4 A g-1 after 2000 cycles). The proposed nanohybrid structure capitalizes on the enhancement of the redox reactions of POM through the PIL linkers to facilitate charge transfer and provide efficient ion transfer channels in the nanohybrid.

Abstract
Realization of the quantum spin Hall effect in graphene devices has remained an outstanding challenge dating back to the inception of the field of topological insulators. Graphene's exceptionally weak spin-orbit coupling-stemming from carbon's low mass-poses the primary obstacle. We experimentally and theoretically study artificially enhanced spin-orbit coupling in graphene via random decoration with dilute Bi2Te3 nanoparticles. Multiterminal resistance measurements suggest the presence of helical edge states characteristic of a quantum spin Hall phase; the magnetic field and temperature dependence of the resistance peaks, x-ray photoelectron spectra, scanning tunneling spectroscopy, and first-principles calculations further support this scenario. These observations highlight a pathway to spintronics and quantum information applications in graphene-based quantum spin Hall platforms.

Abstract
OBJECTIVE To identify ways that provision of hemophilia care can be maximized at the local level, irrespective of available resources or cultural or geographic challenges. METHODS The SHIELD group used its multinational experience to share examples of local initiatives that have been employed to deliver optimal hemophilia care. RESULTS The examples were reviewed and categorized into four key themes: guidelines and algorithms for delivery of care; collaboration with patients and allied groups for care and education; registries for the monitoring of treatment and outcomes and health care planning and delivery; and opportunities for personalization of care. These themes were then incorporated into a road map for collaborative care in hemophilia that reflected the contribution of best practice. DISCUSSION Differing healthcare reimbursement systems, budgetary constraints, and geographical and cultural factors make it difficult for any country to fully deliver ideal care for people with hemophilia. The SHIELD approach for collaborative care provides illustrative examples of how four key themes can be used to optimize hemophilia care in any setting.

Abstract
PURPOSE To determine the association between serum periostin and the presence of diabetic retinopathy (DR). METHODS Serum periostin was detected in 114 healthy subjects, 122 patients with type 2 diabetes mellitus (T2DM) and 159 patients with DR and compared among groups. Clinical data and other laboratory measurements such as glycated hemoglobin (HbA1c), lipid profiles, serum creatinine (Cr) and high-sensitivity CRP (hsCRP) were also collected and compared among groups. For subgroup analysis, patients with DR were divided into a non-proliferated diabetic retinopathy (NPDR) group and a proliferated diabetic retinopathy (PDR) group. Multivariate analysis was performed using logistic regression models. RESULTS The serum periostin level was significantly higher in patients with diabetic retinopathy compared with healthy subjects and patients with T2DM (both P < 0.001, respectively). Also, the periostin level was significantly higher in the PDR group compared to the NPDR group (P = 0.044). Multivariate logistic regression revealed that serum periostin was independently associated with the presence of DR in patients with T2DM (P < 0.001). The receiver operating characteristic (ROC) curves for DR development using serum periostin showed that the area under the receiver operating characteristic curves (AUC) was 0.838 (P < 0.001). CONCLUSIONS The current study demonstrated that serum periostin is significantly associated with the presence of DR in patients with T2DM and is an independent risk factor of DR.

Abstract
Objective: To explore the effects of oleic acid and palmitic acid on lipid deposition and mTOR/S6K1/SREBP-1c pathways in HepG2 cells. Methods: The model of steatosis was established with induction of oleic acid and palmitic acid and was intervened by rapamycin. The changes in lipid droplets were observed after staining the cells with oil Red O. Intracellular triglyceride (TG) contents in cells were measured by TG kit. mTOR, S6K1, and SREBP-1c mRNA expression levels were detected using QRT-PCR. Western blot was used to determine protein expression levels of mTOR, S6K1 and SREBP-1c. Results: Both fatty acids increased lipid droplets in HepG2 cells. Fatty degeneration with elevated TG occurred with significant changes in oleic acid group lipids. Rapamycin alleviated lipid deposition caused by oleic acid and palmitic acid and inhibited their induction of increased expression of mTOR, S6K1, and SREBP-1c. QRT-PCR and Western blot results showed that mRNA and protein expressions of mTOR, S6K1, and SREBP-1c in oleic acid and palmitic acid group were significantly higher than the control group (P < 0.05). The increase was more pronounced in the palmitic acid group (P < 0.05); however, after rapamycin intervention, the expression of mRNA and protein in the three groups were significantly lower (P < 0.05), and the change in palmitic acid group was more pronounced (P < 0.05). Conclusion: Oleic acid and palmitic acid can induce lipid deposition in HepG2 cells and increase expression of every component of mTOR/S6K1/SREBP-1c pathway; however, Oleic acid-induced lipid deposition is more pronounced, and the mTOR, S6K1, and SREBP-1c pathway change is more obvious in palmitic acid. Rapamycin has high potent inhibitory effect on palmitic acid-induced lipid deposition. These results specify that lipid synthesis involved in the mTOR/S6K1/SREBP-1c pathways are mainly associated to palmitic acid in HepG2 cells, whereas other signaling pathway may mediate oleic acid-induced lipid synthesis.

Abstract
Streptococcus mutans and Candida albicans are frequently co-isolated from dental plaque of children with early childhood caries (ECC) and are only rarely found in children without ECC, suggesting that these species interact in a manner that contributes to the pathogenesis of ECC. Previous studies have demonstrated that glucans produced by S. mutans are crucial for promoting the formation of biofilm and cariogenicity with C. albicans; however, it is unclear how non-glucan S. mutans biofilm factors contribute to increased biofilm formation in the presence of C. albicans. In this study we examined the role of S. mutans antigen I/II in two-species biofilms with C. albicans, and determined that antigen I/II is important for the incorporation of C. albicans into the two-species biofilm and is also required for increased acid production. The interaction is independent of the proteins Als1 and Als3, which are known streptococcal receptors of C. albicans. Moreover, antigen I/II is required for the colonization of both S. mutans and C. albicans during co-infection of Drosophila melanogaster in vivo. Taken together, these results demonstrate that antigen I/II mediates the increase of C. albicans numbers and acid production in the two-species biofilm, representing new activities associated with this known S. mutans adhesin.

Abstract
Extracellular ATP is a widespread cell-to-cell signaling molecule in the brain, where it functions as a neuromodulator by activating glia and neurons. Although ATP exerts multiple effects on synaptic plasticity and neuro-glia interactions, as well as in mood disorders, the source and regulation of ATP release remain to be elaborated. Here, we define Calhm2 as an ATP-releasing channel protein based on in vitro and in vivo models. Conventional knockout and conditional astrocyte knockout of Calhm2 both lead to significantly reduced ATP concentrations, loss of hippocampal spine number, neural dysfunction and depression-like behaviors in mice, which can be significantly rescued by ATP replenishment. Our findings identify Calhm2 as a critical ATP-releasing channel that modulates neural activity and as a potential risk factor of depression.

Abstract
Objective: To determine whether thyroid hormone (TH) level could also be an independent and incremental predictor of adverse events in patients with hypertrophic cardiomyopathy (HCM). Methods: A total of 982 consecutive patients with HCM at the National Center for Cardiovascular Diseases (China) from October 2009 to December 2013 were included in the present study, and followed up till the end of December 2016. The patients were divided into three groups according to the levels of free triiodothyronine (FT3): the group 1 (FT3≤4.28 pmol/L, n=335), the group 2 (FT3>4.28-<4.79 pmol/L, n=310), and the group 3 (FT3 4.79-6.30 pmol/L, n=337). Results: After a follow-up period of (53.8±14.1) months, 39 patients (4.0%) either suffered death with all causes or received a cardiac transplantation (7.8%, 2.9% and 1.2% of the patients in the group 1, group 2 and group 3, respectively). A multivariable Cox regression analysis revealed that FT3≤4.28 pmol/L was associated with a significantly higher risk of all-cause mortality or cardiac transplantation (HR 8.83, 95% CI 1.115- 69.905,P=0.039) in HCM patients. Conclusions: Low levels of FT3 is a risk factor of adverse events for patients with HCM, indicting a role of FT3 as a marker for assessing the risk of long-term adverse events in these patients.

Abstract
Objective: To determine the value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) on predicting the long-term outcome of patients with hypertrophic cardiomyopathy (HCM) . Methods: NT-proBNP was measured in 831 consecutive patients with HCM at Fuwai Hospital from October 2009 to December 2013 and patients were followed up clinically for (53.3±15.4) months. Patients were divided into 3 groups according to NT-proBNP values: NT-proBNP<860 pmol/L (n=276) , 860 pmol/L≤NT-proBNP≤1 905 pmol/L (n=278) , NT-proBNP>1 905 pmol/L (n=277) . The related baseline data, laboratory examination and echocardiographic results were compared among groups. The primary endpoints of this study were all-cause mortality and cardiac transplantation. Cox proportional hazards model was used to estimate hazard ratio (HR) . Kaplan-Meier analysis was used to evaluate the survival status of patients among the 3 groups. Results: During a median follow-up of (53.3±15.4) months, all-cause mortality or cardiac transplantation occurred in 37 patients (4.5%) , event rate was 1.4% (4/276) , 4.0% (11/278) and 7.9% (22/277) in patients with NT-proBNP<860 pmol/L, 860 pmol/L≤NT-proBNP≤1 905 pmol/L and NT-proBNP>1 905 pmol/L, respectively. Multivariable Cox regression analysis identified that age (HR 1.066, 95%CI 1.027-1.107) and NT-proBNP (HR 1.026, 95% CI 1.010-1.042) were independent predictors of all-cause mortality or cardiac transplantation. Among the 3 groups, the survival rate of the NT-proBNP<860 pmol/L group was the highest,and that of the NT-proBNP>1 905 pmol/L group was the lowest (P<0.01) . Conclusions: The level of NT-proBNP provides clinically relevant information for long-term adverse events risk stratification in patients with HCM.

Abstract
Abstract
Background: In the U.S., around 252,710 new breast cancer cases will be diagnosed in the year 2017. About 15-20% of these patients will be candidates for treatment with Her-2 directed therapy. The College of American Pathologists (CAP) published initial guidelines for immunohistochemistry (IHC) in 2003 with revisions in 2007 and 2013. 2013 guidelines define 3+(positive) as >10% intense complete membrane staining similar to 2003; >30% complete in 2007. Equivocal 2+ category in 2013 includes incomplete staining > 10% for the first time; this was negative in 2003 and 2007.Hypothesis: The 2013 guidelines do not result in more true positives but increased equivocal cases resulting in clinical uncertainty and increased cost. Methods : A retrospective analysis was performed of all IHC and FISH testing done at a single institution with a single pathology reader from 2003-2016. Criteria for IHC and FISH positivity were followed for each time period and compared to one another for positive and negative HER2 expression. The equivocal categories than compared for outcome by FISH. Ultimate numbers for percentage in each category compared for statistical significance. Results:

When further analysis was carried out, period 1 and 2 were added together and compared to period 3. When all positives and negatives were compared, there was no statistical difference between the periods. However in the equivocal category, Period 1 and 2 were statistically different than period 3. In fact the only change in period 3 was the increase in the equivocal cases (same case-equivocal IHC and FISH).
Conclusion: In the 2013 CAP guidelines, 2+ IHC now includes incomplete staining in >10% of cells. This does not result in more positive cases as was the intention but an increase in the equivocal category by 8.19%. This adds to clinical uncertainty as to how to treat this group of patients. A send out for FISH is labor intensive, slow and costs on average of $650/case. With over 250,000 new cases expected this year in the U.S. this cost exceeds $13million. From all our data, the best parameters for IHC testing would be; positive-strong, complete staining in >10% cells and equivocal to eliminate the incomplete staining category. This would yield the highest number of true positives by FISH and almost eliminate ultimate equivocal cases.

Abstract
Purpose To discuss the intraoperative and postoperative complications of combining phacoemulsification and foldable intraocular lens (IOL) implantation with pars plana vitrectomy in eyes with significant cataract and coexisting vitreoretinal diseases. Methods This retrospective study consisted of 186 eyes of 149 patients with various vitreoretinal abnormalities and visually significant cataracts. Vitreoretinal surgery was combined with clear corneal phacoemulsification and foldable IOL implantation. Main outcome measures were the intraoperative and postoperative complications at from 6 to 56 months. Results The most common intraoperative complication was iatrogenic retinal hole (5.3%), transient corneal edema (3.2%), and posterior capsule break (2.1%). The most common postoperative complication was posterior capsule opacification (21.5%) and elevated intraocular pressure (9.7%), macular edema (8.1%), fibrinous reaction (6.9%), vitreous hemorrhage (3.7%), posterior synechiae (3.7%), and recurrent retinal detachment (3.2%). Postoperatively, in 162 eyes (87.1%), visual acuity improved by 3 lines or more on the Snellen chart. In 14 eyes (7.5%), vision remained within 3 lines of preoperative levels and in 10 eyes (5.3%), vision had decreased at the last follow-up. Conclusions Postoperative complications did not increase significantly in the combined phacoemulsification and vitreoretinal surgery. Combined vitreoretinal surgery and phacoemulsification with foldable IOL implantation is safe and effective in treating vitreoretinal abnormalities coexisting with cataract. Based on extensive experience with the combined procedure, the authors suggest that combined surgery is recommended in select patients having simultaneous vitreoretinal pathologic changes and cataract.

Abstract
The Zeeman splitting and degree of circular polarization (DCP) of photoluminescence (PL) from type-II submonolayer ZnTe/ZnSe quantum dots (QDs) have been investigated in magnetic fields up to 18 T. To explain the observed relative intensities and energy positions of the σ+ and the σ- PL, a non-Boltzmann distribution for holes with ultra-long spin-flip time, confined to submonolayer QDs, is proposed. The g-factor of electrons, located in the ZnSe barriers, was obtained from fitting the temperature dependence of the DCP, and its value is in excellent agreement with that of bulk ZnSe. The g-factor of type-II excitons was extracted by analyzing the Zeeman splitting, from which the g-factor of holes confined within submonolayer ZnTe QDs was found to be ~2.65 ± 0.40. This value is considerably larger than that in bulk ZnTe. Tight-binding calculations using an sp 3 s* model were employed to understand the origin of such an increase. The results of the simulation match the experiment and show that the enhancement of the hole g-factor is mostly caused by a reduced orbital contribution to Zeeman splitting arising from the submonolayer thickness of these QDs.

Abstract
Objective: To investigate the demographic characteristics, clinical features, diagnosis and treatment of patients with gout in China. Methods: Clinical data of 6 814 patients with gout from 100 hospitals in 27 provinces, municipalities or autonomous regions in China were collected and analyzed. Results: (1) The ratio of male to female in patients with gout was 14.7∶1. The mean age of onset was (48.8±15.1) years old. Mean serum urate level was (526.7±132.3) μmol/L. Patients' education background was of U-shaped distribution; (2) Hypertension was the most common comorbidity [15.8%(1 079/6 814)], then overweight or obesity [51.9%(3 536/6 814)]; (3) Alcohol and high-purine food intake were dominant triggering factors in men. The diagnosis of gout was made after onset in majority of patients with cardinal symptom arthralgia. Most patients had the disease less than 5 years, and the longer the course, the more flares in the previous year of entry; (4) Febuxostat was the mostly used urate-lowering medication. 20.7%(1 412/6 814), 10.8%(739/6 814) and 3.9%(265/6 814) of patients were followed up in 4 weeks, 12 weeks and 24 weeks after registration, and 18.9%(267/1 412), 29.1%(215/739) and 38.1%(101/265) of them reached the control target of serum urate levels, respectively. After treatment, patients' liver function was not affected, but serum creatinine levels decreased significantly. Conclusions: The proportion of gout patients who reach target serum urate level is very low. Further steps including education and survey need to be carried on.

Abstract
INTRODUCTION As the pharmacokinetics (PK) of factor VIII (FVIII) is individualized in children with haemophilia A (HA), PK parameters may be indicators of patients' bleeding phenotype and instruction for their personalized replacement program. AIM The aim of this study was to investigate the possible relationship between PK/FVIII level and bleeding frequency in Chinese paediatric patients with severe (HA). METHODS A total of 24 patients were enrolled in Beijing Children's Hospital from February to October 2015, all of whom were given 50 IU/kg of FVIII concentrates after a 72-hours washout period. Samples' activities (FVIII:C) were tested at 5 time points, using WinNonlin software for PK testing, and then the individual half-life(t1/2 ) and the time (h) of FVIII concentrations <1 IU/dL within a week during prophylaxis were calculated. Baseline and the annual bleeding rate (ABR), annual joint bleeding rate (AJBR) were recorded and analyzed. RESULTS The mean t1/2 of FVIII was 10.20 ± 2.72 hours and the mean time of FVIII <1 IU/dL in 1 week was 44.7 hours (-38.56 to 102.33 hours). A significant relationship between t1/2 of FVIII and ABR0 /AJBR0 (baseline bleeding) was found (R2 = 0.75 and 0.62, P < .001). Besides, baseline and the annual bleeding rate during prophylactic treatment of haemophilia had a positive correlation with the time (hours) of FVIII <1 IU/dL in 1 week (R2 = 0.67 and 0.52, P < .001). CONCLUSION t1/2 was an important indicator to prevent bleeding in severe HA; the frequency of bleeding will be reduced with the increased of t1/2 of FVIII. The data also demonstrates that increasing the time with a FVIII<1 IU/dL is associated with an increased rate of bleeding during prophylaxis.

Abstract
With reduced dimensionality, it is often easier to modify the properties of ultrathin films than their bulk counterparts. Strain engineering, usually achieved by choosing appropriate substrates, has been proven effective in controlling the properties of perovskite oxide films. An emerging alternative route for developing new multifunctional perovskite is by modification of the oxygen octahedral structure. Here we report the control of structural oxygen octahedral rotation in ultrathin perovskite SrRuO_{3} films by the deposition of a SrTiO_{3} capping layer, which can be lithographically patterned to achieve local control. Using a scanning Sagnac magnetic microscope, we show an increase in the Curie temperature of SrRuO_{3} due to the suppression octahedral rotations revealed by the synchrotron x-ray diffraction. This capping-layer-based technique may open new possibilities for developing functional oxide materials.

Abstract
Phase separated potassium intercalated FeSe thin films have been synthesized by pulsed laser deposition. The coexistence of FeSe phase and 245 phase was investigated both by x-ray photoemission spectroscopy (XPS) and x-ray diffraction. The volume ratio of these two phases is sensitive to temperatures and amount of extra potassium dosing. The XPS and ultraviolet photoelectron spectroscopy results indicated that these two phases shows the different hybridization strength between adjacent Fe layer and Se layer. We infer that the layered electronic structure is the necessary condition of superconductivity in potassium-doped FeSe system, and the phase separation is driven by competition between quasi-2D and 3D bonding mode within FeSe layer. Similar competition may also be able to interpret the phase seperation in K x Fe2-y Se2 bulk single crystal.
