Abstract
Numerous reported bioinspired osmotic energy conversion systems employing cation-/anion-selective membranes and solutions with different salinity are actually far from the biological counterpart. The iso-osmotic power generator with the specific ionic permselective channels (e.g., K+ or Na+ channels) which just allow specific ions to get across and iso-osmotic solutions still remain challenges. Inspired by nature, we report a bioinspired K+ -channel by employing a K+ selective ligand, 1,1,1-tris{[(2'-benzylaminoformyl)phenoxy]methyl}ethane (BMP) and graphene oxide membrane. Specifically, the K+ and Na+ selectivity of the prepared system could reach up to ≈17.8, and the molecular dynamics simulation revealed that the excellent permselectivity of K+ mainly stemmed from the formed suitable channel size. Thus, we assembled the K+ -selective iso-osmotic power generator (KSIPG) with the power density up to ≈15.1 mW/m2 between equal concentration solutions, which is higher than traditional charge-selective osmotic power generator (CSOPG). The proposed strategy has well shown the realizable approach to construct single-ion selective channels-based highly efficient iso-osmotic energy conversion systems and would surely inspire new applications in other fields, including self-powered systems and medical materials, etc.

Abstract
Interleukin 8 (IL8) is a CXC chemokine that plays a crucial role on promoting inflammatory response and immune regulation. In teleost, IL8 can induce the migration and activation of immune cells. However, the biological functions of IL8 are still unknown in Takifugu rubripes. In this study, we examined the biological characteristics of TrIL8 in T. rubripes. TrIL8 is composed of 98 residues and contained a chemokine CXC domain. We found that the TrIL8 expression was detected in diverse organs and significantly increased by Vibrio harveyi or Edwardsiella tarda challenge. The recombinant TrIL8 (rTrIL8) exhibited significantly the binding capacities to 8 tested bacteria. In addition, rTrIL8 could bind to peripheral blood leukocytes (PBL), and increased the expression of immune gene, resistance to bacterial infection, respiratory burst, acid phosphatase activity, chemotactic activity, and phagocytic activity of PBL. In the presence of rTrIL8, T. rubripes was enhanced the resistance to V. harveyi infection. These results indicated that TrIL8 is a chemokine and involved in the activation of immune cells against bacterial infection in teleost.

Abstract
Mechanical force loading is essential for maintaining bone homeostasis, and unloading exposure can lead to bone loss. Osteoclasts are the only bone resorbing cells and play a crucial role in bone remodeling. The molecular mechanisms underlying mechanical stimulation-induced changes in osteoclast function remain to be fully elucidated. Our previous research found Ca2+-activated Cl- channel Anoctamin 1 (Ano1) was an essential regulator for osteoclast function. Here, we report that Ano1 mediates osteoclast responses to mechanical stimulation. In vitro, osteoclast activities are obviously affected by mechanical stress, which is accompanied by the changes of Ano1 levels, intracellular Cl- concentration and Ca2+ downstream signaling. Ano1 knockout or calcium binding mutants blunts the response of osteoclast to mechanical stimulation. In vivo, Ano1 knockout in osteoclast blunts loading induced osteoclast inhibition and unloading induced bone loss and. These results demonstrate that Ano1 plays an important role in mechanical stimulation induced osteoclast activity changes.

Abstract
Major depressive disorder is a global mental illness associated with severe mortality and disability. The dopaminergic system is involved in both the etiology and therapeutics of depression. Distinct functions of dopamine D1 and D2 receptor subtypes have attracted considerable research interest, and their roles in the pathogenesis of depression and interaction with antidepressants need to be comprehensively elucidated. Herein, we investigated the antidepressant effects of a candidate antidepressant from a cinnamamide derivative, M2, and examined underlying neural mechanisms. We observed that a single dose of M2 (30 mg/kg, ip) produced rapid antidepressant-like effects in mice subjected to the forced swim and tail suspension tests. Using whole-cell recordings in mouse coronal brain slices, we found that application of M2 (10-150 μM) concentration-dependently increased the frequency of spontaneous excitatory postsynaptic currents (sEPSCs) of the pyramidal neurons in the medial prefrontal cortex (mPFC). Furthermore, M2-induced enhancement of sEPSC frequency was abolished by sulpiride (10 µM), a dopamine D2 receptor antagonist, but not by the dopamine receptor D1 antagonist, SCH23390 (10 μM). In addition, M2 administration significantly increased expression levels of synaptogenesis-related proteins, including p-mTOR and p-TrkB, in the mPFC at 30 min, and increased postsynaptic protein PSD-95 at 24 h. Our results demonstrated that M2 produces rapid antidepressant actions through a novel mechanism via dopamine D2 receptor-mediated enhancement of mPFC neurotransmission.

Abstract
OBJECTIVE In this review, we aimed to discuss the efficacy of immunotherapy of anti-programmed cell death protein 1 (PD-1) and programmed death ligand 1 (PD-L1) and potential immune mechanism combination with various standard systemic therapies for breast cancer (BC) such as chemotherapy, targeted therapy, endocrine therapy, and radiotherapy. BACKGROUND Single-drug therapy of antibodies against PD-1 and its ligand, PD-L1, have only presented modest responses in patients with BC, partly due to the deficiency of tumor-infiltrating lymphocytes (TILs) and low mutation burden. Thus, the combinations of PD-1/PD-L1 blockade with other approaches which may increase the immune therapy effect are being studied. Moreover, an understanding of the immune mechanism of PD-1/PD-L1 blockade with other approaches will contribute to better application of clinical therapy. METHODS We searched the studies that focus on PD-1/PD-L1 therapy with or without other systemic therapy and relative immune mechanisms indicated between 2000 and 2020. CONCLUSIONS Anti PD-1/L1 blockade combined with therapeutic approaches is safe and effective in BC, in particular for PD-L1 antibody atezolizumab plus nab-paclitaxel by inducing PD-1/L1 expression and the number of cytotoxic T cells. Otherwise, the toxicity also exists during clinical treatment. Future researches should be evaluated to explore the immune mechanism and vast clinical trials need to be conducted for evidential support for combination therapy of BC.

Abstract
Abstract
Background
Marfan syndrome (MFS) is an autosomal dominant connective tissue disorder caused by mutations in the Fibrillin1 gene (FBN1) that leads to impaired elastin formation and extra-cellular matrix homeostasis. Elastin synthesis and related lamellae formation in the aorta is completed in the newborn. Thereafter further elastin turnover is thought to be minimal during life. Elastin homeostasis is little studied in patients with MFS who have been reported to have reduced elastin in their aorta and are at risk of aortic dilatation and consequent life-threatening dissection. It is not clear if elastin loss is due to reduced elastin formation in utero or accelerated degradation during life. However, aortopathy develops early in MFS with 70% of patients developing aortic dilatation by the age of 20 years. Therefore, the longitudinal and circumferential aortic growth that occurs in childhood may involve elastic lamellae remodelling that is impaired in MFS. Desmosine is the cross-link component in the elastin molecule and is exclusively released from mature elastin breakdown, thus is a physiologically relevant biomarker of elastin turnover. We hypothesise that physiologic aortic growth is associated with elastic lamellae remodelling and increased elastin turnover, detected by elevated plasma desmosine (pDES), and that elastin turnover is exaggerated during the fast-growing period in MFS.
Purpose
The aims of this study were 1. To investigate the relationship between elastin turnover and age in the control subjects, and 2. To compare the elastin turnover in MFS with control subjects.
Methods
pDES was measured by stable isotope dilution LC-MS/MS in 113 MFS subjects (48% male, mean age 18.2±9.4 (SD) years), mean aortic root 33.8±2.1mm and Z-score 3.4±2.1 in the AIMS trial at baseline before intervention, and in 109 healthy controls (46% male, mean age 26.1±9.5 years).
Results
pDES levels were associated positively with age, body surface area and negatively with diastolic BP in the control group (p=0.05 and 0.21 respectively after correcting for age). In MFS subjects pDES also positively correlated with age and male sex (p<0.05). Interestingly, the age-dependent association with pDES showed a peak distribution in both control and MFS groups (Figure 1) where teenage children expressed the highest pDES levels. MFS subjects had significantly higher pDES compared to controls before the age of 20 (p=0.01) but in adulthood, there was no difference (Figure 2).
Conclusion
Elastin turnover is highly dynamic before early adulthood, and peaks in adolescence and is exaggerated in MFS, suggesting that this period of growth is critical in developing aortopathy.

Abstract
Background: Patients with chronic obstructive pulmonary disease (COPD) are more susceptible to Aspergillus colonization or infection. Several studies have demonstrated that invasive pulmonary Aspergillosis (IPA) and Aspergillus hypersensitivity (AH) have a detrimental effect on COPD. However, it remains to be clarified whether Aspergillus colonization is associated with acute exacerbation of COPD (AECOPD). This study aimed to explore the impact of Aspergillus colonization in the lower respiratory tract on AECOPD. Method: Patients with Aspergillus colonization were identified from a retrospective cohort of hospitalized AECOPD from 2011 to 2016 in eight centers in Shanghai, China. The demographic information, conditions of the stable stage, clinical characteristics during hospitalization, and 1-year follow-up information after discharge were collected and compared to participants without fungi colonization. Result: Twenty-six hospitalized AECOPD patients with Aspergillus colonization and 72 controls were included in the final analysis after excluding patients with other fungi isolation and matching. The rates of recurrence of acute exacerbation within 90 days and 180 days after discharge in the patients with Aspergillus colonization were both significantly higher than that in the fungi negative patients (90 days: 19.2 vs. 4.2%, p = 0.029; 180 days: 23.1 vs. 4.2%, p = 0.010), and the all-cause mortality within 1 year was also higher (11.5 vs. 0.0%, p = 0.017). Multivariate logistic regression analysis showed that Aspergillus colonization was an independent risk factor for the recurrence of acute exacerbation within 90 days and 180 days (90 days: OR = 8.661, 95% CI: 1.496-50.159, p = 0.016; 180 days: OR =10.723, 95% CI: 1.936-59.394, p = 0.007). Conclusion:Aspergillus colonization may predict poor prognosis of AECOPD while leading to an increased risk of recurrent AECOPD in a short period.

Abstract
OBJECTIVE To investigate the epidemiology, clinical features, treatment and outcome of Noninvasive ventilation (NIV)-treated acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients in secondary hospitals of Shanghai. METHOD Relying on Shanghai alliances for respiratory diseases, a retrospective observational study was performed in 34 secondary hospitals of Shanghai. The AECOPD patients treated with NIV and admitted to the respiratory department or respiratory intensive care unit were recruited between December 1, 2016, and November 30, 2017. RESULTS There were 555 patients finally recruited in this study. The age was 75.8 ± 9.6 years old and 380 patients (68.5%) were male. 70.5% of all patients had respiratory acidosis (pH <7.35). 55.3% of all patients received nebulised bronchodilator and 77.7% were treated with systemic or inhaled corticosteroids during hospitalisation. 525 patients (94.6%) recovered successfully and the mortality was 3.2%. The hospitalisation was 15.3 ± 6.7 days and hospital expenses were 22 911 ± 13 595 RMB. Inadequate and nonstandard drug treatments were the most important problems during management. CONCLUSION The NIV can be successfully used for AECOP patients in local hospitals of Shanghai, but accompanied by high costs and long hospital stays. However, the treatments for exacerbation and stable COPD patients are still insufficient.

Abstract
The act of observing a quantum object fundamentally perturbs its state, resulting in a random walk toward an eigenstate of the measurement operator. Ideally, the measurement is responsible for all dephasing of the quantum state. In practice, imperfections in the measurement apparatus limit or corrupt the flow of information required for quantum feedback protocols, an effect quantified by the measurement efficiency. Here, we demonstrate the efficient measurement of a superconducting qubit using a nonreciprocal parametric amplifier to directly monitor the microwave field of a readout cavity. By mitigating the losses between the cavity and the amplifier, we achieve a measurement efficiency of (72±4)%. The directionality of the amplifier protects the readout cavity and qubit from excess backaction caused by amplified vacuum fluctuations. In addition to providing tools for further improving the fidelity of strong projective measurement, this work creates a test bed for the experimental study of ideal weak measurements, and it opens the way toward quantum feedback protocols based on weak measurement such as state stabilization or error correction.

Abstract
Micro ribonucleic acid (miRNA) is a type of noncoding RNA, and it has been revealed to play important roles in the activity of the mammary gland (MG) in some species. However, the function of miRNAs in MG of sheep is poorly understood. In the study, Gansu Alpine Merino (GAM; n = 9) and Small-tailed Han sheep (STH; n = 9) with different milk production traits were investigated. Microstructures and the expression profile of miRNAs of MG tissues at peak lactation were studied. Mature alveolar lumens of MG in appearance were larger in STH than GAM. The expression levels of CSN2 and the content of rough endoplasmic reticulum were also higher in STH ewes than GAM ewes. A total of 124 mature miRNAs were expressed, and 18 of these were differentially expressed between the 2 breeds. The KEGG analysis results showed that the targeted genes of differentially expressed miRNAs were mainly involved in some metabolic pathways and signaling pathways related to MG development, milk protein, and fat synthesis. The findings in the study can improve our understanding of the roles of miRNAs in the development and lactation of MG in sheep.

Abstract
Objective: To explore impact of Candida on the acute exacerbation of chronic obstructive pulmonary disease (AECOPD) outcome. Methods: A retrospective, multi-center, case-control study was performed. Patients hospitalized for AECOPD in 25 centers during Jan 2011-Dec 2016 were enrolled. Data were collected, including demographic information, conditions during the stable phase of COPD, clinical characteristics of AECOPD, and follow-up information within 1 year after discharge. Univariate analysis and binary logistic regression were applied, and p < 0.05 was regarded as significant. Results: Totally 1,103 patients were analyzed, with 644 lower respiratory airway (LTR) Candida positive cases and 459 Candida negative controls. Long-term prognosis was significantly different between Candida positive and negative group, including the recurrent AECOPD within 180 days (75.5 vs. 6.6%, p < 0.001) and mortality within 1 year (6.9 vs. 0.4%, p < 0.001). Univariate logistic analysis showed that LTR Candida isolation was related to higher recurrence rate of AECOPD within 180 days and mortality within 1 year. Binary logistic regression analysis demonstrated that LTR Candida isolation was independently associated with recurrence of AECOPD within 180 days. Conclusions: LTR Candida isolation was associated with worse long-term prognosis of AECOPD and independently related to higher risks of recurrent AECOPD within 180 days.

Abstract
Background The outbreak of COVID-19 has led to international concern. We aimed to establish an effective screening strategy in Shanghai, China, to aid early identification of patients with COVID-19. Methods We did a multicentre, observational cohort study in fever clinics of 25 hospitals in 16 districts of Shanghai. All patients visiting the clinics within the study period were included. A strategy for COVID-19 screening was presented and then suspected cases were monitored and analysed until they were confirmed as cases or excluded. Logistic regression was used to determine the risk factors of COVID-19. Findings We enrolled patients visiting fever clinics from Jan 17 to Feb 16, 2020. Among 53 617 patients visiting fever clinics, 1004 (1·9%) were considered as suspected cases, with 188 (0·4% of all patients, 18·7% of suspected cases) eventually diagnosed as confirmed cases. 154 patients with missing data were excluded from the analysis. Exposure history (odds ratio [OR] 4·16, 95% CI 2·74-6·33; p<0·0001), fatigue (OR 1·56, 1·01-2·41; p=0·043), white blood cell count less than 4 × 109 per L (OR 2·44, 1·28-4·64; p=0·0066), lymphocyte count less than 0·8 × 109 per L (OR 1·82, 1·00-3·31; p=0·049), ground glass opacity (OR 1·95, 1·32-2·89; p=0·0009), and having both lungs affected (OR 1·54, 1·04-2·28; p=0·032) were independent risk factors for confirmed COVID-19. Interpretation The screening strategy was effective for confirming or excluding COVID-19 during the spread of this contagious disease. Relevant independent risk factors identified in this study might be helpful for early recognition of the disease. Funding National Natural Science Foundation of China.

Abstract
Objective: To investigate the clinical efficacy of Laparoscopic cornuotomy on Interstitial Tubal Pregnancy (IP) which diameter was shorter than 3 cm. Methods: The women who had IP under 3 cm diameter were selected from January, 2016 to December, 2018 at the Department of Gynecology, JiaXing Maternity and Child Health care Hospital. A total of 32 IP patients were divided into two groups. They were all treated with laparoscopic surgery. 17 patients were in study group, conducted by a cornuotomy and suturing the cornual.15 patients were in control group, conducted by a cornual resection and suturing the cornual. Patients' genenral conditions were not significantly different(all P values>0.05). The peri-surgical data and the related clinical data were compared in the two groups. Results: All the 32 patients were successfully treated by laparoscopic surgery. The mean operating time was significantly shorter for cornuotomy than for cornual resection[ (33±6) min vs (53±9) min, P<0.05].Changes in blood loss[(45±5) ml vs (50±7) ml]、the total hospital stays[ (4.4±1.4) d vs (4.6±1.4) d] and the recovery time of HCG[(16±5) d vs (15±5) d] were not significantly different between the two groups (all P values>0.05) . There were no persistent ectopic pregnancy and uterine rupture happened in two groups. Compared with the control group,the interval time to pregnancy was shorter[ (8±3) m vs (16±4) m, P<0.05] and the number of full-term pregnancy cases were more (9 vs 3, P<0.05). Conclusion: The Laparoscopic cornuotomy was feasible and safe on interstitial tubal pregnancy which diameter was shorter than 3cm. It deserved popularization in the clinical work and regarded as one of selection operative treatment on interstitial heterotopic pregnancy.

Abstract
Background Despite the release of a national guideline in 2016, the actual practices with respect to adult community-acquired pneumonia (CAP) remain unknown in China. We aimed to investigate CAP patient management practices in Shanghai to identify potential problems and provide evidence for policy making. Methods A short-period, 5-day prospective cross-sectional study was performed with sampled pulmonologists from 36 hospitals, encompassing all the administrative districts of Shanghai, during January 8–12, 2018. The medical information was recorded and analyzed for the patients with the diagnosis of CAP who were cared for by 46 pulmonologists during the study period. Results Overall, 435 patients were included in the final analysis, and 94.3% had a low risk of death in terms of CRB-65 criteria (C: disturbance of consciousness, R: respiratory rate, B: blood pressure, 65: age). When diagnosed with CAP, 70.1% of patients were not evaluated using the CURB-65 score (CRB-65 + U: urea nitrogen), but most patients (95.4%) were evaluated using CRB-65. Time to achieve clinical stability was longer in patients with hypoxemia than in those without hypoxemia (8.42±6.36 vs. 5.53±4.12 days, P=0.004). Overall, 84.4% of patients with a CRB-65 score of 0 were administered antibiotics intravenously, and 19.4% were still hospitalized after excluding hypoxemia and comorbidities. The average duration of antibiotic treatment was 10.4±4.9 days. Overall, 72.6% of patients received antibiotics covering atypical pathogens whose time to clinical stability was significantly shortened compared with those without coverage, but the antibiotic duration was similar and not correspondingly shortened. Conclusions CRB-65 seems to be more practical than CURB-65 for the initial evaluation of CAP in the context of local practice, and oxygenation assessment should be included in the evaluation of severity. Overtreatment may be relatively common in patients at low risk of death, including unreasonable hospitalization, intravenous administration, and antibiotic duration.

Abstract
Objective: To investigate the effect of modified tubal resection or ligation on the incidence of interstitial pregnancy during the re-pregnancy. Methods: Patients who underwent tubal resection or ligation in our hospital from June 2017 to June 2019 were selected as research subjects and randomly divided into observation group and control group, with 43 cases in each group.The observation group received modified tubal resection or ligation, while the control group received traditional tubal resection or ligation, and the occurrence of re-gestation interstitial pregnancy was followed up. Results: A total of 86 subjects were included, with an average age of (32.3±2.6) years old, 2-5 pregnancies, and 2-4 births. There was no statistical difference in general data between the two groups.The success rate of operation in both groups was more than 95%, with 6.98% (3/43) patients in the observation group having temporary fever and other discomforts after operation, and 9.30%(4/43) patients in the control group having good outcomes.In the observation group and the control group, 36 and 34 patients underwent in vitro fertilization and embryo transfer three months after the operation, respectively, and 23 pregnancies were successful in each group. All pregnancies in the observation group were intrauterine, and no ipsilateral tubal interstitial pregnancy occurred; in the control group, 19 were intrauterine pregnancies, and 4 cases of ipsilateral tubal interstitial pregnancy occurred.Ipsilateral tubal interstitial pregnancy after modified tubal ligation was significantly lower than that after traditional tubal resection or ligation (χ(2)=4.195, P=0.041). Conclusion: Modified tubal ligation and resection can effectively reduce the occurrence of interstitial pregnancy during the re-pregnancy.

Abstract
We present a new optomechanical device where the motion of a micromechanical membrane couples to a microwave resonance of a three-dimensional superconducting cavity. With this architecture, we realize ultrastrong parametric coupling, where the coupling not only exceeds the dissipation in the system but also rivals the mechanical frequency itself. In this regime, the optomechanical interaction induces a frequency splitting between the hybridized normal modes that reaches 88% of the bare mechanical frequency, limited by the fundamental parametric instability. The coupling also exceeds the mechanical thermal decoherence rate, enabling new applications in ultrafast quantum state transfer and entanglement generation.

Abstract
In this article, a series of novel quinoline derivatives of ursolic acid (UA) bearing hydrazide, oxadiazole, or thiadiazole moieties were designed, synthesised, and screened for their in vitro antiproliferative activities against three cancer cell lines (MDA-MB-231, HeLa, and SMMC-7721). A number of compounds showed significant activity against at least one cell line. Among them, compound 4d exhibited the most potent activity against three cancer cell lines with IC50 values of 0.12 ± 0.01, 0.08 ± 0.01, and 0.34 ± 0.03 μM, respectively. In particular, compound 4d could induce the apoptosis of HeLa cells, arrest cell cycle at the G0/G1 phase, elevate intracellular reactive oxygen species level, and decrease mitochondrial membrane potential. In addition, compound 4d could significantly inhibit MEK1 kinase activity and impede Ras/Raf/MEK/ERK transduction pathway. Therefore, compound 4d may be a potential anticancer agent and a promising lead worthy of further investigation.

Abstract
STUDY QUESTION Is pinopode measurement of any prognostic value? SUMMARY ANSWER Pinopode expression was significantly associated with the occurrence of pregnancy after frozen embryo transfer. WHAT IS KNOWN ALREADY Pinopodes are expressed in the endometrium during the implantation period. Pinopode measurement has been proposed as a marker of endometrial receptivity. STUDY DESIGN, SIZE, DURATION A prospective cohort study was conducted at the Center of Reproductive Medicine, Sir Run Run Shaw Hospital, between 2014 and 2016, recruiting 172 women with infertility and undergoing frozen embryo transfer following IVF treatment. Among 172 participants, 46 women took part in the first study to quantify the daily changing pattern of pinopodes 3-7 days after the initiation of progesterone therapy in the hormone replacement cycles and the remaining 126 women with infertility participated in a study to examine the relationship between pinopode count and pregnancy outcome following frozen embryo transfer in hormone replacement cycles. PARTICIPANTS/MATERIALS, SETTING, METHODS The mean age of participants was 29 years old. All participants received an artificial hormone replacement protocol capable of supporting successful implantation. Endometrial biopsies from 46 women were obtained 3, 4, 5, 6 and 7 days after the initiation of progesterone therapy (P + 3, n = 6; P + 4, n = 6; P + 5, n = 11; P + 6, n = 13; P + 7, n = 10, respectively). Another 126 endometrial biopsies were obtained precisely 6 days after the initiation of progesterone. Scanning electron microscopy was used to capture the pinopode images, followed by use of the image J program to quantify the count and subtype of the pinopodes. MAIN RESULTS AND THE ROLE OF CHANCE We found that at least 60 microscopic fields were necessary to achieve a reproducible result. An intra-observer variability study showed good agreement between two measurements regarding the developing pinopode (DP) subtype (r = 0.95) and the fully developed pinopode (FDP) subtype (r = 0.86) but not for the regressing (RP) pinopode subtype (r = 0.39). The proportion of DP/total pinopodes (TP) declined rapidly form day P + 4 to a minimum on day P + 6. The percentage of FDP/TP increased rapidly from day P + 4 to reach a peak on day P + 6. On the other hand, the percentage of RP/TP reached a peak on day P + 7. Participants who conceived had a significantly (P = 0.011) higher percentage of FDP/TP on day P + 6 and significantly (P = 0.005) lower percentage of DP/TP on the same day compared with participants who did not become pregnant. Using a scoring system incorporating the percentages of DP and FDP, it was found that the pregnancy rate and the embryo implantation rate of women with a high pinopode score (82.3%; 63.0%) was significantly (P = 0.001; P = 0.046) higher than that of women with a low pinopode score (53.3%; 46.7%), respectively. There remains a possibility that the observations could have arisen due to chance. LIMITATIONS, REASONS FOR CAUTION This study examined pinopode count and subtype in the HRT cycles, and it is uncertain whether the same observations apply to in natural cycles. WIDER IMPLICATIONS OF THE FNDINGS Pinopodes have been questioned as a potential marker of endometrial receptivity for many years. Our results suggested that pinopode measurement may be of value in predicting pregnancy. STUDY FUNDING/COMPETING INTEREST(S) The study was supported by the grants from the general project of medicine and health in Zhejiang Province of China (2015KYA142; 2018KY106), the Key Research and Development Program of Zhejiang Province (2017C03022) and the National Natural Science Foundation of China (81701514).The funders had no role in the study design, data collection and analysis, decision to publish or preparation of the manuscript. We have no competing interests to declare. TRIAL REGISTRATION NUMBER ISRCTN26300668.

Abstract
A series of novel 2-aryl-benzimidazole derivatives of dehydroabietic acid were synthesized and characterized by IR, 1H NMR, 13C NMR, MS and elemental analyses. All the target compounds were evaluated for their in vitro cytotoxic activity against SMMC-7721, MDA-MB-231, HeLa and CT-26 cancer cell lines and the normal hepatocyte cell line QSG-7701 through MTT assays. Among them, compound 6j displayed the most potent cytotoxic activity with IC50 values of 0.08 ± 0.01, 0.19 ± 0.04, 0.23 ± 0.05 and 0.42 ± 0.07 μM, respectively, and substantially reduced cytotoxicity against QSG-7701 cells (5.82 ± 0.38 μM). The treatment of SMMC-7721 cells with compound 6j led to considerable inhibition of cell migration ability. The influence of compound 6j on cell cycle distribution was assessed on SMMC-7721 cells, exhibiting a cell cycle arrest at the G2/M phase. Moreover, tubulin polymerization assays and immunofluorescence assays elucidated that compound 6j could significantly inhibit tubulin polymerization and disrupt the intracellular microtubule network. A molecular docking study provided insight into the binding mode of compound 6j in the colchicine site of tubulin. In addition, compound 6j was found to induce apoptosis of SMMC-7721 cells, an increase of intracellular ROS level and a loss of mitochondrial membrane potential in a dose-dependent manner. These findings provided new molecular scaffolds for the further development of novel antitumor agents targeting tubulin polymerization.

Abstract
Long non-coding RNAs (lncRNAs) serve critical roles in the pathogenesis of various cancers, including lung adenocarcinoma (LUAD). Herein, in this study, we aimed to investigate the biological and clinical significance of lncRNA DiGeorge syndrome critical region gene 5 (DGCR5) in LUAD. It was observed that DGCR5 was upregulated in LUAD tissues and LUAD cell lines. Inhibition of DGCR5 can prevent LUAD progression via playing anti-apoptosis roles. Both mRNA expression and protein levels of BCL-2 were increased by DGCR5 downregulation while reversely BAX was increased. Additionally, a novel microRNA target of DGCR5, hsa-mir-22-3p was identified through bioinformatics search and confirmed by dual-luciferase reporter system. Gain and loss-of-function studies were performed to verify whether DGCR5 exerts its biological functions through regulating hsa-mir-22-3p in vitro. Overexpression of DGCR5 was able to reverse the tumor inhibitory effect of hsa-mir-22-3p mimics. Furthermore, in vivo tests tumor xenografts were established to detect the function of DGCR5 in LUAD tumorigenesis. Downregulated DGCR5 expression was greatly associated with smaller tumor size, implying a favorable prognosis of LUAD patients. Taken these together, DGCR5 could be considered as a prognostic biomarker and therapeutic target in LUAD diagnosis and treatment.

Abstract
OBJECTIVES To study the genetic polymorphisms of 30 insertion/deletion (InDel) loci and evaluate their forensic application in Ewenki ethnic group from Inner Mongolia. METHODS Peripheral blood samples were collected from 87 unrelated healthy individuals in Ewenki ethnic group. Genomic DNA were extracted, and 30 InDel loci of the samples were multiplex amplified and genotyped. Hardy-Weinberg balance tests were preformed for all loci and genetic parameters were calculated by modified PowerStats v1.2 software. The linkage disequilibrium between loci were tested by SNPAnalyzer v2.0 software. Based on the allele frequencies of 30 InDel loci, the genetic relationships between Ewenki ethnic group and other populations were evaluated by analysis of molecular variance, principal component analysis and phylogenetic reconstruction. RESULTS After correction, 30 InDel loci conformed to Hardy-Weinberg equilibrium. It was found that the pairwise InDel loci were in linkage equilibrium after Bonferroni correction. The results of population genetics indicated that Ewenki ethnic group had close genetic relationships with Henan Han and Beijing Han populations; whereas it was significantly different from several populations in Europe and Mexico. CONCLUSIONS There are relatively high genetic polymorphisms on 30 InDel loci of Ewenki ethnic group from Inner Mongolia, which can be used as a helpful supplement application for STR detection system.

Abstract
A series of new quinoline derivatives of ursolic acid were designed and synthesized in an attempt to develop potential anticancer agents. The structures of these compounds were identified by 1H NMR, 13C NMR, IR and ESI-MS spectra analysis. The target compounds were evaluated for their in vitro cytotoxicity against three human cancer cell lines (MDA-MB-231, Hela and SMMC-7721). From the results, compounds 3a-d displayed significant antitumor activity against three cancer cell lines. Especially, compound 3b was found to be the most potent derivative with IC50 values of 0.61±0.07, 0.36±0.05, 12.49±0.08μM against MDA-MB-231, HeLa and SMMC-7721 cells, respectively, stronger than positive control etoposide. Furthermore, the Annexin V-FITC/PI dual staining assay revealed that compound 3b could significantly induce the apoptosis of MDA-MB-231 cells in a dose-dependent manner. The cell cycle analysis also indicated that compound 3b could cause cell cycle arrest of MDA-MB-231 cells at G0/G1 phase.

Abstract
A series of new 1H-benzo[d]imidazole derivatives of dehydroabietic acid were designed and synthesized as potent antitumor agents. Structures of the target molecules were characterized using MS, IR, 1H NMR, 13C NMR and elemental analyses. In the in vitro cytotoxic assay, most compounds showed significant cytotoxic activities against two hepatocarcinoma cells (SMMC-7721 and HepG2) and reduced cytotoxicity against noncancerous human hepatocyte (LO2). Among them, compound 7b exhibited the best cytotoxicity against SMMC-7721 cells (IC50: 0.36±0.13μM), while 7e was most potent to HepG2 cells (IC50: 0.12±0.03μM). The cell cycle analysis indicated that compound 7b caused cell cycle arrest of SMMC-7721 cells at G2/M phase. Further, compound 7b also induced the apoptosis of SMMC-7721 cells in Annexin V-APC/7-AAD binding assay.

Abstract
OBJECTIVE To validate the effectiveness, repeatability and treatment responsiveness of the Chinese version of Hull airway reflux questionnaire (HARQ), and to determine its clinical value. METHODS A standard Chinese version of HARQ was developed by an established translation procedure and its repeatability was assessed in a preliminary study involving 55 untreated patients with stable chronic cough. Thereafter, a total of 132 patients with chronic cough referred to our respiratory clinic were recruited into the study between May 2014 and April 2015. After their cough was evaluated with the HARQ, cough symptom score or cough reflex sensitivity to inhaled capsaicin and the correlations among them were analyzed, and the causes of chronic cough in all the patients were presumptively determined according to an established diagnostic protocol and finally confirmed with the subsequent therapy specific to the etiologies. After two weeks of effective treatment, HARQ, cough symptom score and cough reflex sensitivity to inhaled capsaicin were measured once more, and treatment responsiveness was calculated. The score of the HARQ in 132 patients with chronic cough were compared with that in 104 healthy volunteers. RESULTS The repeatability of the Chinese version of the HARQ was validated at a week interval with the intraclass correlation coefficients of 0.96 (95%CI: 0.93-0.98, P=0.00) for total score (n=55). No correlation was found between the HARQ and cough symptom score, and the HARQ showed a weak negative correlation with cough threshold C2 (rIgC2=-0.23, P=0.01) but not with C5. The value of HARQ was significantly higher in patients with chronic cough than in healthy volunteers[20.00(14.00, 28.00) vs 4.00 (2.00, 6.00), Z=-12.89, P=0.00], but no difference of HARQ in gender or age existed in chronic cough. Although all the patients with various etiologies of chronic cough had an increased value of HARQ, cough due to gastroesophageal reflux showed the highest HARQ score among them[28.50 (25.00, 32.25) vs 18.50 (14.00, 26.25), Z=4.43, P=0.00]. After two weeks of effective treatment, the HARQ score decreased from 20.00 (14.00, 28.00) pre-treatment to 10.00 (4.25, 17.75) post-treatment (Z=-6.06, P=0.00), with 52.04% of score change ratio, 1.38 of effect side and 1.97 of standard response mean respectively. CONCLUSION HARQ is a reliable and valid tool for the management of chronic cough with good treatment responsiveness, and may be used as an easy way to predict cough due to gastroesophageal reflux.

Abstract
PURPOSE We explored and compared the clinical effects of whole-brain radiotherapy (wbrt) with and without elemene liposomes in patients with multiple brain metastases from non-small-cell lung carcinoma (nsclc). METHODS We retrospectively analyzed 62 patients with multiple brain metastases from nsclc who received wbrt (30 Gy in 10 fractions) at Shengjing Hospital of China Medical University from January 2012 to May 2013. In 30 patients, elemene liposomes (400 mg) were injected intravenously via a peripherally inserted central catheter for 21 consecutive days from the first day of radiotherapy. Overall survival (os) and nervous system progression-free survival (npfs) for the two groups were compared by Kaplan-Meier analysis. Factors influencing npfs were examined by Cox regression analysis. Chi-square or Fisher exact tests were used for group comparisons. RESULTS The median os was 9.0 months in the wbrt plus elemene group and 7.8 months in the wbrt-alone group (p = 0.581); the equivalent median npfs durations were 5.2 months and 3.7 months (p = 0.005). Patient treatment plan was an independent factor associated with npfs (p = 0.002). Tumour response and disease-control rates in the wbrt plus elemene group were 26.67% and 76.67% respectively; they were 18.75% and 62.5% in the wbrt group (p = 0.452). Compared with the patients in the wbrt-alone group, significantly fewer patients in the wbrt plus elemene group developed headaches (p = 0.04); quality of life was also significantly higher in the wbrt plus elemene group both at 1 month and at 2 months (p = 0.021 and p = 0.001 respectively). CONCLUSIONS The addition of elemene liposomes to wbrt might prolong npfs in patients with multiple brain metastases from nsclc, while also reducing the incidence of headache and improving patient quality of life.

Abstract
OBJECTIVE To study the genotyping characteristics and antibiotic resistance of methicillin-resistant Staphylococcus aureus(MRSA) isolated from lower respiratory tract at 2 different level hospitals in Shanghai. METHODS The subjects included 155 patients at Ruijin Hospital and Tongren Hospital between January 2013 and June 2014, including 108 males and 47 females, with a mean age of 67.8±16.5. The 155 MRSA strains were isolated from lower respiratory tract specimens and multilocus sequence typing (MLST) and spa typing were analyzed by the PCR method. The antimicrobial resistance of MRSA was tested by VITEK-32. Fisher's exact test was used for statistical analysis. RESULTS Among the 155 strains, 28 MLST-spa molecular types were identified, of which ST764-t002(41.29%), ST239-t037(17.42%) and ST239-t030(10.32%) were the most predominant types. The MRSA strains were susceptible to linezolid, vancomycin and teicoplanin, and also had a lower resistance to trimethoprim-sulfamethoxazole and rifampin, with a susceptible rate of 83.9% and 83.2% respectively, but were highly resistant to other antibiotics. The resistance rate of ST239-t037 to trimethoprim-sulfamethoxazole was higher than that of other types, and the resistance rate of ST239-t030 to rifampin was higher than that of other types, the differences being significant(P<0.001). The mean length of hospital stay of the 155 patients was (97±84) days, and mechanical ventilation were used in 78(50.3%) patients, while 108(69.7%))patients received invasive procedures. Broad-spectrum antibiotics were used in 136 (87.1%) patients. There were differences in age, hospitalization days, smoking history, history of COPD, mechanical ventilation, and operation between the 2 hospitals(P<0.05). CONCLUSION Most of the MRSA strains at Ruijin Hospital and Tongren Hospital between January 2013 and June 2014 were multi-drug resistant, and the susceptibility spectrum of different genotypes was different.

Abstract
BACKGROUND Recent studies have shown that T helper type-2 (Th2) cells can induce the apoptosis of CD4+CD25+ Treg cells or resist the immunosuppressive effect of Treg cells. We hypothesize that an imbalance of Th2/Treg is present in patients with allergic asthma. METHODS Twenty-two patients with mild asthma, 17 patients with moderate to severe asthma, and 20 healthy donors were enrolled. All patients were allergic to house dust mites. The proportion of peripheral blood CD4+CD25+ Treg cells and Th2 cells were determined by flow cytometry. The concentration of interleukin (IL)-10, transforming growth factor (TGF)-β and IL-4 in plasma was determined by enzyme linked immunosorbent assay. In these subjects, peripheral blood mononuclear cells from 17 mild asthmatic patients, 13 moderate to severe asthmatic patients and 14 healthy donors were acquired and expression of forkhead box P3 (Foxp3) and GATA-3 mRNA was detected by reverse-transcriptase polymerase chain reaction. RESULTS Compared with healthy donors and patients with mild asthma, the percent of CD4+CD25+ Treg cells and plasma IL-10 levels were decreased in patients with moderate to severe asthma. There were no significant differences in Foxp3 mRNA expression among three groups, but a downward trend seen among patients with asthma. However, the percent of Th2 cells, IL-4 levels and expression of GATA-3 mRNA was markedly higher in patients with mild and moderate to severe asthma than in the control group. The ratio of Th2/Treg and their cytokines was increased in allergic asthma, especially for moderate to severe asthma. The ratio of GATA-3/Foxp3 mRNA was also increased in allergic asthma. In patients with moderate to severe asthma, the percentage of peripheral blood Treg cells was negatively correlated to the percentage of Th2 cells and IL-4 levels. CONCLUSIONS The decline of CD4+CD25+ Treg cells in patients with moderate to severe asthma may play an important role in progress of the disease. Furthermore, the deficiency of CD4+CD25+ Treg cells was associated with the over-expression of Th2 response.

Abstract
We investigated the association between CASP-9 polymorphisms and susceptibility to neoplasm. Fourteen studies with a total of 2733 neoplasm cases and 3352 healthy controls were included. Meta-analysis showed that the rs4645981 T allele and the rs4645981 T allele carrier were positively associated with neoplasm susceptibility [odds ratio (OR) = 1.43, 95% confidence interval (95%CI) = 1.12-1.81, P = 0.004; OR = 1.46, 95%CI = 1.10-1.93, P = 0.009, respectively]. However, the rs1052576 A allele, rs1052576 A carrier, rs2308941 T allele, and rs2308941 T carrier might decrease the risk of cancer (OR = 0.72, 95%CI = 0.58-0.89, P = 0.003; OR = 0.76, 95%CI = 0.63-0.92, P = 0.004; OR = 0.20, 95%CI = 0.09-0.45, P < 0.0001; OR = 0.21, 95%CI = 0.06-0.75, P = 0.02, respectively). There was no significant association between rs1263, rs1052571, rs2308950, rs4645978, rs4645980, rs4645982, and rs4646018 and cancer risk (all P > 0.05). In conclusion, this meta-analysis suggests that CASP-9 gene polymorphisms are involved in the pathogenesis of various cancers. The rs4645981 T allele and the rs4645981 T allele carrier might increase the risk of cancer, but the rs1052576 A allele, rs1052576 A carrier, rs2308941 T allele, and rs2308941 T carrier might be protective.

Abstract
We made a meta-analysis of the association between X-ray cross-complementing gene 1 (XRCC1) genetic polymorphism Arg399Gln and esophageal cancer (EC) risk. Statistical analysis was performed with the Review Manager version 4.2.8 software program and STATA version 11.0. We selected 16 case-control studies for this meta-analysis, including 3591 EC cases and 5752 controls. Overall, the Gln399 allele was not associated with EC risk, compared with the Arg399 allele in the populations included in the analysis. However, stratified analysis revealed that the Gln399 allele was associated with increased EC risk among the Chinese population in a recessive model [odds ratio (OR) = 1.42; 95% confidence interval (95%CI) = 1.07-1.90; P = 0.02 for heterogeneity] and by homozygote contrast (OR = 1.43; 95%CI = 1.05-1.96; P = 0.02 for heterogeneity), particularly for the tumor histology of squamous cell carcinoma (OR = 1.46; 95%CI = 1.10-1.95 for the recessive model and OR = 1.42; 95%CI = 1.03-1.95 for the homozygote contrast). We conclude that the XRCC1 Arg399Gln polymorphism has potential as a biomarker for EC susceptibility in the Chinese population, particularly for squamous cell carcinoma.

Abstract
The caspase (CASP) gene family is known to be involved in apoptosis, cytokine maturation, cell growth, and differentiation. A large number of single nucleotide polymorphisms (SNPs) in the CASP gene family have been increasingly recognized as important regulators in the development of lung cancer. However, this specific association is still controversial. In this Human Genome Epidemiology review and meta-analysis, we summarized the available evidence associating lung cancer with the CASP gene family. Seven studies, which included 1155 lung cancer cases and 1120 healthy controls, met the inclusion criteria and were included in our meta-analysis. In seven studies, 19 different SNPs have been studied in seven CASP genes, including CASP-1, -2, -5, -7, -8, -9, and -10. Meta-analysis results showed positive associations between heterozygote (A/G) of rs507879 in the CASP-5 gene, the T allele of rs12415607 in the CASP-7 gene, and the T allele and T carrier (C/T+T/T) of rs4645981 in the CASP-9 gene with lung cancer susceptibility [odds ratio (OR) = 1.83, 95% confidence interval (95%CI) = 1.07-3.12, P = 0.03; OR = 1.18, 95%CI = 1.02-1.37, P = 0.03; OR = 1.43, 95%CI = 1.12-1.81, P = 0.004; OR = 1.46, 95%CI = 1.10-1.93, P = 0.009; respectively]. However, we found that homozygote (G/G) of rs2227310 in the CASP-7 gene, del allele, heterozygote (ins/del), and del carrier (ins/del + del/del) of rs3834129 in CASP-8 could be protective factors for lung cancer (OR = 0.17, 95%CI = 0.14-0.21, P = 0.0003; OR = 0.83, 95%CI = 0.72-0.97, P = 0.02; OR = 0.74, 95%CI = 0.64-0.85, P < 0.0001; OR = 0.81, 95%CI = 0.71-0.93, P = 0.002; respectively). In conclusion, based on this meta-analysis, we suggest that SNPs in CASP-5, -7, -8, and -9 are associated with susceptibility to lung cancer.

Abstract
PURPOSE This study was to evaluate the influence of radiotherapy on the selenium serum levels of non-small cell cancer patients with brain metastases. PATIENTS AND METHODS This prospective study included 95 non-small cell cancer patients with brain metastases treated by radiotherapy from December 2007 until November 2010. Plasma selenium levels were determined before and at the end of the radiotherapy. Age, body mass index (BMI), prior chemotherapy, pathological type and personal habits (smoking and alcoholism) were recorded for each patient. RESULTS The mean age was 63 years; the mean BMI was 27.6. Seventy-six patients (80%) were non-smokers. Sixty-two patients (65.3%) showed no drinking habits and 8 (8.4%) have no prior chemotherapy. Thirty-nine patients (41.1%) were adenocarcinoma, 51 (53.7%) were squamous cell carcinoma and five (5.3%) were large cell carcinoma. At the beginning of radiotherapy, the mean selenium level for all patients was 90.4 μg/l and after radiation this value dropped to 56.3 μg/l. Multivariate analysis showed statistically significant difference in the plasma selenium concentration before and after radiotherapy for age (P<0.001), BMI (P<0.001), smoking (P<0.001), alcoholism (P<0.001), prior chemotherapy (P<0.001) and pathological type (P<0.001). CONCLUSION Significant reduction in plasma levels of selenium was recorded in patients undergoing radiotherapy, suggesting attention to the nutritional status of this micronutrient and other antioxidant agents.

Abstract
PURPOSE To determine the safety and radiation-enhancing effect of sodium glycididazole in laryngeal squamous cell carcinoma (stage T3-4,N0-3,M0) with conventional radiotherapy. PATIENTS AND METHODS Patients with locoregional advanced laryngeal cancer (stage T3-4,N0-3,M0) were included: group 1(control, n=30)were not administered of sodium glycididazole; group 2 (test, n=30) received sodium glycididazole at a dose of 700 mg/m(2) intravenous infusion 30 minutes before radiotherapy three times a week. Surrogate end-points of efficacy were tumor and nodal size. Safety parameters were vomiting, nausea, mucositis, laryngeal edema, esophagus and skin reaction, dysphagia, dyspnea, neurological deficit. Patients were evaluated weekly during treatment for 7 weeks and thereafter monthly for 3 months. RESULTS In the test, the overall response rate was 88.89% (95%CI, 71.00-97.00%) at 7 weeks and 92.59% (95%CI, 76.00 to 99.00%) at 1 month of follow-up. In the control, the overall response rate was 62.5% (95%CI, 41.00 to 81.00%) at 7 weeks and 58.33% (95%CI, 37.00 to 78.00%) at 1 month of follow-up. The short-term locoregional response rate was better in the test group at 7 weeks (p=0.027) and at 1 month (p=0.005) of follow-up. The test group had significantly more nausea and vomiting in weeks 1 (p=0.047), 2 (p=0.007), and 3 (p=0.01) of treatment. CONCLUSIONS The study indicates sodium glycididazole is an effective radiation-enhancing agent that improves short-term locoregional control and is well tolerated in patients with locoregionally advanced laryngeal cancer.

Abstract
We have investigated macroscopic quantum tunneling in Bi(2)Sr(2)CaCu(2)O(8 + delta) intrinsic Josephson junctions at millikelvin temperatures using microwave irradiation. Measurements show that the escape rate for uniformly switching stacks of Nu junctions is about Nu(2) times higher than that of a single junction having the same plasma frequency. We argue that this gigantic enhancement of the macroscopic quantum tunneling rate in stacks is boosted by current fluctuations which occur in the series array of junctions loaded by the impedance of the environment.

Abstract
OBJECTIVE Atheromatous ascending aortic aneurysms (AAA) frequently present with aortic regurgitation (AR) from dilatation of the sino-tubular junction (STJ) and extension of the pathological process into the root. Experience suggests that root dilatation begins in the non-coronary, then right coronary sinus. Rather than employ aortic root replacement or the David procedure, we have elected to replace the ascending aorta and remodel the STJ and involved sinuses. We studied the outcome after selective sinus replacement in 29 consecutive AAA patients between 1995 and 2001. METHODS There were nine male and 20 females. Age ranged from 47 to 79 years (mean 67.5). Seven had arch aneurysms and four coronary artery disease. Nineteen were NYHA III or IV. Grade of AR was IV in 20, III in five and II in four. The STJ was dilated >50% of annulus diameter in each case (5.3-10.0 cm, mean 6.4 cm). All valves had three cusps. All patients underwent ascending aortic replacement. Seven had arch replacement and four coronary artery bypass. Seven had replacement of both right and non-coronary sinuses with re-implantation of the right coronary ostium. Twelve had replacement of the non-coronary sinus alone whilst nine had right coronary sinus replacement. One with dextrocardia had left coronary sinus replacement with ostial re-implantation. The graft size was within 2 mm of annulus size except for two patients (24 mm 12, 26 mm 11, and 28 mm six). Post operative echocardiographic studies were performed. None of the patients received anticoagulation. RESULTS There were no hospital or late deaths and no thromboembolic or infective complications. Two patients had mild to moderate aortic regurgitation. These had a size 28 graft, which in retrospect was too large. Others had no significant regurgitation. CONCLUSIONS The native aortic valve can be preserved in the majority of patients with AAA. Remodelling of the STJ and selective sinus replacement restores valve competence. Anticoagulation and prosthesis related complications are thereby avoided.

Abstract
The objective of this study was to determine the effects of sizing policy for pericardial stentless valves on hemodynamic performance and aortic root geometry. Discharge echocardiography was performed on 103 patients out of 110 consecutive implants (54 men and 49 women, mean age 75 +/- 9 years, and 36% with Co-CABG). Valve prosthesis size was based on largest annulus size plus 1 to 2 mm in the first 50 implants (group A, n = 48). Following continuous echo assessment, sizing policy was changed to annulus size plus 3 to 4 mm in the next 60 implants (group B, n = 55). Sinotubular (ST) junction was kept within 115% of the annulus size by surgical remodeling of aortic root. In comparison with group A, group B had a 7% larger valve size (25.2 +/- 2.1 mm v 23.6 +/- 2.3, mm, P <.01) implanted for patients of same body surface area and left ventricular cavity size. However, group B has a 38% lower mean pressure gradient (4.0 +/- 2.7 v 6.5 +/- 3.2, mm Hg, P <.01), a 32% greater effective orifice area (2.3 +/- 0.9 cm(2) v 1.7 +/- 0.7 cm(2), P <.01), better root distensibility (9.3% +/- 6.0% v 6.8% +/- 4.1%, P =.026), and a lower ratio of ST junction to valve size (0.92 +/- 0.13 v 0.99 +/- 0.14, P =.009). Group B also had lower grade of prosthesis regurgitation (0.35 +/- 0.62 v 0.89 +/- 1.1, P =.002). Sizing of pericardial stentless aortic valves by annulus diameter plus 3 to 4 mm provides better valve competence and hemodynamic efficiency by improving aortic root geometry and distensibility. Pericardial stentless valves may be of advantage in elderly patients with significant geometric root mismatch.

Abstract
Long-term clinical and hemodynamic performance is a key consideration in using a stentless aortic bioprosthesis. This study reports clinical and hemodynamic performance of Prima stentless aortic valve during our 8-year follow-up. In the study, 85 patients underwent aortic valve replacement (Edwards Prima or Prima plus stentless valve) and had follow-up at discharge and then annually up to 8 years. The mean age at operation was 72 +/- 5 yrs, 49 were male and 25% underwent concomitant CABG. Doppler Echo studies were performed to determine mean pressure gradient (mPG), effective orifice area (EOA) and the degree of regurgitation of stentless valves. Aortic root geometry was assessed by the ratio of sinotubular junction to valve size at peak systole. Patient survival rate was 82% +/- 5% at 5th year and 72% +/- 6% at 8th year. The freedom from valve structure failure was 97% +/- 2% at 5th and 8th year. Valve mPG and EOA at 8 years remained significantly better than those at discharge (6.8 +/- 4.4 mm Hg v 9.7 +/- 6.2 mm Hg; 1.91 +/- 0.54 cm(2) v 1.63 +/- 0.71 cm(2), both P <.01), and did not differ from those at 3-year follow-up. Mean sinotubular junction diameter remained below valve size (0.96 +/- 0.14). Mild degree of valvular regurgitation was present in 17% of patients, but this did not progress over the period of follow-up. After aortic valve replacement with the Prima stentless valves, excellent valve hemodynamics and normal root geometry were well maintained up to 8 years, but longer-term follow-up of a larger cohort remains essential.

Abstract
The objective of this study was to elucidate the relationship of aortic pressure gradient (mPG) and effective orifice area (EOA) with mean systolic flow rate of left ventricle in patients who received a stentless aortic valve. Two hundred thirteen patients (age: 73 +/- 6 years, 123 men and 90 women) who received a Freestyle stentless valve in subcoronary position for aortic valve diseases were studied. EOA, mPG, and systolic aortic flow rate were determined by Doppler echocardiography at 1 and 20 months after implant. With follow-up, there was a 13% increase in EOA and a 30% decrease in mPG, both P <.01. Although systolic aortic flow did not change, the intercept of EOA-flow relationship increased significantly at late follow-up (0.56 +/- 0.13 v 0.11 +/- 0.13, P <.01). Multiple regression analysis showed that systolic aortic flow accounted for 54%, and mPG for only 27%, variation of EOA. Linear relationship between EOA and systolic aortic flow provides a comprehensive approach to describe stentless valve performance, when mean valve pressure gradient appears to be flow independent. These hemodynamic features distinguish stentless valves from stented or mechanical prosthesis. Ultimately, the variations in aortic root anatomy, surgical experience and their interactions are likely to become major determinants of in vivo performance of stentless aortic valves.

Abstract
Stentless aortic bioprostheses (SBPs) convey hemodynamic and perhaps survival benefit over stented counterparts. The aim of this study was to determine whether the more taxing operation increases surgical risk. We studied contemporary multicenter (USA) data submitted to the Food and Drug Administration (FDA) for Freestyle stentless (group I, n = 583) and Mosaic stented xenograft approval (group II, n = 1260). The study compared 30-day mortality for the two groups overall, then for isolated aortic valve replacement (AVR) and for AVR and coronary bypass (CABG). Because the USA Freestyle valves were used in selected patients (pts) we included SBP data (group III) from Oxford, where Freestyle valves were used consecutively within the same time frame. We also reviewed hospital mortality in the stentless bioprosthesis literature and compared this with the Society of Thoracic Surgery Database. There were no differences in age, NYHA, or incidence of CABG between the groups. There was no significant difference in operative mortality between stented (group II) and exclusive (group III) SBP patient groups (P =.233 for AVR and P =.478 for AVR + CABG), or between selective (group I) and exclusive (P =.929 for AVR and P =.390 for AVR + CABG) groups, after adjustment for risk factors. However, there was a significantly higher mortality both for isolated AVR (P =.026) and AVR + CABG (P =.001) in the selected stentless group compared with stented. This was partly attributed to greater mortality when the Freestyle was used in elderly patients by the full root replacement method, and to the higher proportion of females, and subjects with intra-aortic balloon pump insertion in this group. A meta-analysis of published stentless valve series, showed mortality rates to be lower than those of the STS National Database average. During the learning curve selective use of SBPs increased hospital mortality for AVR +/- CABG. Consecutive use dispelled the difference and the literature now suggests that SBPs may reduce hospital mortality for high-risk patients.
