Abstract
BACKGROUND Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac anomaly, mortality rates in infancy reach approximately 90%, with only a small number of patients surviving into adulthood, therefore, most of the literature reports mainly focus on infantile type. CASE PRESENTATION A 55-year-old female was admitted due to persistent repeated chest pain experienced and had worsened for unknown reasons. Color doppler echocardiography, coronary computed tomographic angiography, and coronary angiography confirmed the diagnosis of ALCAPA and concurrent right coronary artery-right atrial fistula. The symptoms of chest pain exhibited notable improvement subsequent to corrective surgery for the anomalous origin of the coronary artery. CONCLUSIONS This report shows an unique case of ALCAPA in an adult patient, characterizing the condition's combination with a right coronary-right atrial fistula, and it is prone to misdiagnosis and misdiagnosis. We aim to provide valuable insights for clinical diagnosis and treatment of ALCAPA.

Abstract
Doxorubicin (DOX) is an anthracycline antineoplastic agent that has limited clinical utility due to its dose-dependent cardiotoxicity. Although the exact mechanism remains unknown, inflammatory responses have been implicated in DOX-induced cardiotoxicity (DIC). In this study, we analyzed the transcriptomic, metabolomic as well as lipidomic changes in the DOX-treated mice to explore the underlying mechanisms of DIC. We found that continuous intraperitoneal DOX injections (3 mg/kg/d) for a period of five days significantly induced cardiac dysfunction and cardiac injury in male C57BL/6 J mice (8 weeks old). This corresponded to a significant increase in the myocardial levels of IL-4, IL-6, IL-10, IL-17 and IL-12p70. Furthermore, inflammation-related genes such as Ptgs2, Il1b, Cxcl5, Cxcl1, Cxcl2, Mmp3, Ccl2, Ccl12, Nfkbia, Fos, Mapk11 and Tnf were differentially expressed in the DOX-treated group, and enriched in the IL-17 and TNF signaling pathways. Besides, amino acids, peptides, imidazoles, toluenes, hybrid peptides, fatty acids and lipids such as Hex1Cer, Cer, SM, PG and ACCa were significantly associated with the expression pattern of inflammation-related genes. In conclusion, the integration of transcriptomic, metabolomic and lipidomic data identified potential new targets and biomarkers of DIC.

Abstract
Endoplasmic reticulum (ER) stress plays a central role in myocardial ischemia/reperfusion (I/R) injury. Irisin has been reported to have protective properties in ischemia disease. In this study, we aimed at investigating whether irisin could alleviate myocardial I/R injury by ER stress attenuation. The in vitro model of hypoxia/reoxygenation (H/R) was established, which resembles I/R in vivo. Cell viability and apoptosis were estimated. Expressions of cleaved caspase-3, cytochrome c, GRP78, pAMPK, CHOP, and eIF2α were assessed by western blot. Our results revealed that pre-treatment with irisin significantly decreased cytochrome c release from mitochondria and caspase-3 activation caused by H/R. Irsin also reduced apoptosis and increased cell viability. These effects were abolished by AMPK inhibitor compound C pre-treatment. Also, GRP78 and CHOP expressions were up-regulated in the H/R group compared to the control group; however, irisin attenuated their expression. The pAMPK level was significantly decreased compared to the control, and this effect could be partly reversed by metformin pre-treatment. These results suggest that ER stress is associated with cell viability decreasing and cardiomyocytes apoptosis induced by H/R. Irisin could efficiently protect cardiomyocytes from H/R-injury via attenuating ER stress and ER stress-induced apoptosis.

Abstract
Background It is known that increased gastrin concentration is negatively correlated with cardiovascular mortality, and plasma gastrin levels are increased in patients after myocardial infarction (MI). However, whether gastrin can play a protective role in MI remains unknown. Methods Adult C57BL/6 mice were subjected to ligation of the left anterior descending coronary artery (LAD) and subcutaneous infusion of gastrin (120 μg/Kg body weight/day, 100 μL in the pump) for 28 days after MI. Plasma gastrin concentrations were measured through an ELISA detection kit. Mice were analyzed by echocardiography after surgery. CD31 and VEGF expression were quantified using immunofluorescence staining or/and western blot to assess the angiogenesis in peri-infarct myocardium. Capillary-like tube formation and cell migration assays were performed to detect gastrin-induced angiogenesis. Results We found that gastrin administration significantly ameliorated MI-induced cardiac dysfunction and reduced fibrosis at 28 days in post-MI hearts. Additionally, gastrin treatment significantly decreased cardiomyocyte apoptosis and increased angiogenesis in the infarct border zone without influencing cardiomyocyte proliferation. In vitro results revealed that gastrin up-regulated the PI3K/Akt/vascular endothelial growth factor (VEGF) signaling pathway and promoted migration and tube formation of human coronary artery endothelial cells (HCAECs). Cholecystokinin 2 receptor (CCK2R) mediated the protective effect of gastrin since the CCK2R blocker CI988 attenuated the gastrin-mediated angiogenesis and cardiac function protection. Conclusion Our data revealed that gastrin promoted angiogenesis and improved cardiac function in post-MI mice, highlighting its potential as a therapeutic target candidate.

Abstract
Doxorubicin (DOX) is a widely used antitumor drug that causes severe cardiotoxicity in patients; no effective strategy yet exists to address this problem. We previously reported that 8-formylophiopogonanone B (8-FOB), a natural isoflavone in Ophiopogon japonicas, antagonizes paraquat-induced hepatotoxicity. Here, we explored the mechanisms underlying DOX-induced cardiotoxicity as well as whether 8-FOB can alleviate DOX-induced cardiotoxicity. Acute cardiotoxicity was established by injecting C57BL/6J mice with a single dose of DOX (20 mg/kg, intraperitoneal). To elucidate the mechanisms underlying DOX-induced cardiotoxicity, differentially expressed genes between hearts from DOX-treated and control mice were identified from the Gene Expression Omnibus (GEO) database via GEO2R. Using the Cytoscape software plugin cytoHubba, five hub genes associated with DOX-induced cardiotoxicity were identified: CD68, PTEN, SERPINE1, AIF1, and HMOX1. However, of these, only HMOX1 protein expression levels were significantly increased after DOX treatment. We also confirmed that HMOX1-dependent myocardial inflammation and fibrosis were closely associated with DOX-induced cardiotoxicity. More importantly, 8-FOB protected against DOX-cardiotoxicity by ameliorating cardiac injury and dysfunction, reducing cardiac fibrosis and inflammatory cytokine release, and inhibiting HMOX1 expression. In conclusion, our results suggest that inhibition of HMOX1-dependent myocardial inflammatory insults and fibrosis is essential for 8-FOB to ameliorate DOX-caused cardiotoxicity.

Abstract
Ischemia reperfusion (I/R)-induced arrhythmia is a serious complication in patients with cardiac infarction. Remodeling of connexin (Cx) 43, manifested as phosphorylation, contributes significantly to arrhythmogenesis. Integrin-linked kinase (ILK) attenuated ventricular remodeling and improved cardiac function in rats after myocardial infarction. We hypothesized that ILK, through Cx43 phosphorylation, would be protective against I/R-induced ventricular arrhythmias. Our study showed that I/R-induced ventricular arrhythmias were attenuated by an ILK agonist LPTP and worsened by the ILK inhibitor Cpd22. I/R disrupted Cx43 distribution, but it was partially normalized in the presence of LPTP. Compared with I/R, the phosphorylation of Akt was increased significantly after pretreatment with LPTP. The increase in phosphorylated Akt was physiologically significant because, in the presence of the Akt inhibitor MK2206, the protective effects of LPTP were blocked. This indicated that ILK activation prevented I/R-induced-ventricular arrhythmia, an effect potentially related to inhibition of Cx43 remodeling via Akt activation.

Abstract
BACKGROUND Ischemia/reperfusion injury (IRI) is one of the most predominant complications of ischemic heart disease. Gastrin has emerged as a regulator of cardiovascular function, playing a key protective role in hypoxia. Serum gastrin levels are increased in patients with myocardial infarction, but the pathophysiogical significance of this finding is unknown. The purpose of this study was to determine whether and how gastrin protects cardiac myocytes from IRI. METHODS AND RESULTS Adult male Sprague-Dawley rats were used in the experiments. The hearts in living rats or isolated Langendorff-perfused rat hearts were subjected to ischemia followed by reperfusion to induce myocardial IRI. Gastrin, alone or with an antagonist, was administered before the induction of myocardial IRI. We found that gastrin improved myocardial function and reduced the expression of myocardial injury markers, infarct size, and cardiomyocyte apoptosis induced by IRI. Gastrin increased the phosphorylation levels of ERK1/2 (extracellular signal-regulated kinase 1/2), AKT (protein kinase B), and STAT3 (signal transducer and activator of transcription 3), indicating its ability to activate the RISK (reperfusion injury salvage kinase) and SAFE (survivor activating factor enhancement) pathways. The presence of inhibitors of ERK1/2, AKT, or STAT3 abrogated the gastrin-mediated protection. The protective effect of gastrin was via CCK2R (cholecystokinin 2 receptor) because the CCK2R blocker CI988 prevented the gastrin-mediated protection of the heart with IRI. Moreover, we found a negative correlation between serum levels of cardiac troponin I and gastrin in patients with unstable angina pectoris undergoing percutaneous coronary intervention, suggesting a protective effect of gastrin in human cardiomyocytes. CONCLUSIONS These results indicate that gastrin can reduce myocardial IRI by activation of the RISK and SAFE pathways.

Abstract
Primary cilia, with highly regulated cellular sensory functions, play key roles in tissue development and function maintenance. Intraflagellar transport 140 (IFT140) is a subunit of IFT complex A, which is specialized for retrograde transportation in cilia. Mutations of Ift140 are usually associated with syndromic ciliopathy and may cause isolated diseases such as retinal dystrophy, short ribs, and polycystic kidney. However, the role of IFT140 in tooth development has not been well investigated. In this study, a close relationship between IFT140 and dentin formation is disclosed. During tooth development, IFT140 was highly expressed in odontoblasts. To further understand the role of IFT140 in dentinogenesis, Ift140flox/flox/Osx-Cre mouse was generated. The dentin thickness of Ift140flox/flox/Osx-Cre mouse is thinner and the dentin formation is slower than that in control. In vitro, deletion of IFT140 in odontoblasts led to poor odontogenic differentiation, abnormal primary cilia, and decreased Sonic hedgehog signaling molecules. More important, due to loss of primary cilia in odontoblasts by IFT140 deletion, reparative dentin formation was impaired in a tooth-drilling model. These results suggest that cilia gene IFT140 is essential in promoting dentin formation and reparation.

Abstract
BACKGROUND Adult mammalian hearts have a limited ability to generate new cardiomyocytes. Proliferation of existing adult cardiomyocytes (ACMs) is a potential source of new cardiomyocytes. Understanding the fundamental biology of ACM proliferation could be of great clinical significance for treating myocardial infarction (MI). We aim to understand the process and regulation of ACM proliferation and its role in new cardiomyocyte formation of post-MI mouse hearts. METHODS β-Actin-green fluorescent protein transgenic mice and fate-mapping Myh6-MerCreMer-tdTomato/lacZ mice were used to trace the fate of ACMs. In a coculture system with neonatal rat ventricular myocytes, ACM proliferation was documented with clear evidence of cytokinesis observed with time-lapse imaging. Cardiomyocyte proliferation in the adult mouse post-MI heart was detected by cell cycle markers and 5-ethynyl-2-deoxyuridine incorporation analysis. Echocardiography was used to measure cardiac function, and histology was performed to determine infarction size. RESULTS In vitro, mononucleated and bi/multinucleated ACMs were able to proliferate at a similar rate (7.0%) in the coculture. Dedifferentiation proceeded ACM proliferation, which was followed by redifferentiation. Redifferentiation was essential to endow the daughter cells with cardiomyocyte contractile function. Intercellular propagation of Ca2+ from contracting neonatal rat ventricular myocytes into ACM daughter cells was required to activate the Ca2+-dependent calcineurin-nuclear factor of activated T-cell signaling pathway to induce ACM redifferentiation. The properties of neonatal rat ventricular myocyte Ca2+ transients influenced the rate of ACM redifferentiation. Hypoxia impaired the function of gap junctions by dephosphorylating its component protein connexin 43, the major mediator of intercellular Ca2+ propagation between cardiomyocytes, thereby impairing ACM redifferentiation. In vivo, ACM proliferation was found primarily in the MI border zone. An ischemia-resistant connexin 43 mutant enhanced the redifferentiation of ACM-derived new cardiomyocytes after MI and improved cardiac function. CONCLUSIONS Mature ACMs can reenter the cell cycle and form new cardiomyocytes through a 3-step process: dedifferentiation, proliferation, and redifferentiation. Intercellular Ca2+ signal from neighboring functioning cardiomyocytes through gap junctions induces the redifferentiation process. This novel mechanism contributes to new cardiomyocyte formation in post-MI hearts in mammals.

Abstract
BACKGROUND Transplantation of cardiosphere-derived cells (CDCs) has been shown to exert a therapeutic effect in patients with myocardial infarction (MI). However, poor survival of transplanted CDCs limits their beneficial effect. Metformin (MET) activates AMP-activated protein kinase (AMPK) which is associated with cell survival. The aim of this study is to determine whether MET improves CDC survival in the transplantation microenvironment and enhances the therapeutic effect of CDC transplantation against MI. METHODS CDCs were isolated and expanded from transgenic β-actin-GFP mice. CDCs were pretreated with MET and intramyocardially injected into wild-type C57 mouse heart with MI injury. The survival of CDCs was quantified, and the infarct size and cardiac function of treated hearts were evaluated. RESULTS CDC transplantation modestly reduced infarct size and improved cardiac function in the post-MI heart, which was further improved by MET treatment. MET pretreatment significantly increased the survival of CDCs transplanted into the myocardium. MET also reduced CDC apoptosis induced by oxidative stress in vitro. The anti-apoptotic effect of MET was blocked by the AMPK inhibitor compound C. MET increased AMPK phosphorylation and upregulated endothelial nitric oxide synthase (eNOS) in CDCs under oxidative stress, which might be associated with the anti-apoptotic effect of MET. CONCLUSIONS MET improves the survival of transplanted CDCs in the myocardium, thereby enhancing their therapeutic effect against MI injury. The pro-survival function of MET on CDCs might be associated with an AMPK-eNOS-dependent mechanism.

Abstract
Proliferation of vascular smooth muscle cells (VSMCs) is thought to have a key role in the development of atherosclerotic lesions. Neuropeptide Y (NPY), norepinephrine and dopamine are sympathetic neurotransmitters. NPY has been particularly shown to stimulate proliferation of VSMCs. NPY, norepinephrine and dopamine are all sympathetic transmitters. In our previous study, we found that in the presence of the dopamine receptor, the α1-adrenergic receptor-mediated VSMC proliferation is reduced. We hypothesize that the activation of the D1-like receptor might inhibit the NPY-mediated VSMC proliferation. In our present study, we found that NPY, mainly via the Y1 receptor, increased VSMC proliferation. This was determined by [(3)H]-thymidine incorporation, in a concentration (10(-11) to 10(-8) M)-dependent manner. In the presence of the D1-like receptor agonist, fenoldopam (10(-12) to 10(-5) M), the stimulatory effect of NPY on VSMC proliferation was reduced. The involvement of the D1-like receptor was confirmed when the inhibitory effect of fenoldopam was reversed in the presence of the D1-like receptor antagonist SCH-23390 (10(-8) M). Moreover, the inhibitory effect of fenoldopam on NPY-mediated VSMC proliferation was also blocked in the presence of the PKA inhibitor 14-22 (10(-6) M). Protein kinase A activator 8-(4-chlorophenylthio) adenosine-3,5-cyclic monophosphorothioate, Sp-isomer sodium salt (10(-6) M) could simulate the stimulatory effect of fenoldopam. It indicated that the inhibitory effect of D1-like receptors on NPY-mediated VSMC proliferation may have an important role in the regulation of blood pressure or prevention of atherosclerosis.

Abstract
Mitochondrial (mt) dysfunction and oxidative stress are involved in the pathogenesis of ischemia/reperfusion (I/R)-injury. Lycopene, a lipophilic antioxidant found mainly in tomatoes and in other vegetables and fruits, can protect mtDNA against oxidative damage. However, the role of mtDNA in myocardial I/R-injury is unclear. In the present study, we aimed to determine if and how lycopene protects cardiomyocytes from I/R-injury. In both in vitro and in vivo studies, I/R-injury increased mt 8-hydroxyguanine (8-OHdG) content, decreased mtDNA content and mtDNA transcription levels, and caused mitochondrial dysfunction in cardiomyocytes. These effects of I/R injury on cardiomycoytes were blocked by pre-treatment with lycopene. MtDNA depletion alone was sufficient to induce cardiomyocyte death. I/R-injury decreased the protein level of a key activator of mt transcription, mitochondrial transcription factor A (Tfam), which was blocked by lycopene. The protective effect of lycopene on mtDNA was associated with a reduction in mitochondrial ROS production and stabilization of Tfam. In conclusion, lycopene protects cardiomyocytes from the oxidative damage of mtDNA induced by I/R-injury.

Abstract
Calpain plays an important role in myocardial ischemia/reperfusion (I/R) injury. PD150606, a nonpeptide, cell-permeable and noncompetitive calpain inhibitor, has been shown to have protective properties in ischemic disease. The aims of the present study were to investigate whether PD150606 could alleviate myocardial I/R injury and to examine the possible mechanisms involved. The I/R model was established in vivo in C57BL/6 mice and in vitro using neonatal mouse cardiomyocytes, respectively. To evaluate the protective effects of PD150606 on I/R injury, we measured the myocardial infarct area, apoptosis, and expression of cleaved caspase-3. We also investigated the underlying mechanisms by examining mitochondrial function as reflected by the ATP concentration, translocation of cytochrome c, dynamics of mPTP opening, and membrane potential (ΔΨm), coupled with calpain activity. Pretreatment with PD150606 significantly reduced the infarct area and apoptosis caused by I/R. PD150606 pretreatment also reduced mitochondrial dysfunction by inhibiting calpain activation. Moreover, we found that μ-calpain is the main contributor to I/R-induced calpain activation. Knockdown of μ-calpain with siRNA significantly reversed calpain activation, mitochondrial dysfunction, and cardiomyocyte apoptosis caused by I/R in vitro. Our results suggest that PD150606 may protect against I/R injury via preventing μ-calpain-induced mitochondrial apoptosis.

Abstract
Angiotensin type 1a receptor (AT1aR) is thought to play an important role in the development of hypertension. However, it is unknown how the AT1aR expression in vascular tissue is changed during the development of hypertension or if the degree of methylation in the AT1aR promoter correlates with the expression of AT1aR. To address these questions, we measured AT1aR mRNA, protein expression, and methylation status of the AT1aR promoter in the aorta and mesenteric artery of male spontaneously hypertensive rats (SHRs) and age-matched Wistar-Kyoto (WKY) rats acting as controls at pre-hypertensive (4 weeks), evolving (10 weeks), and established (20 weeks) stages of hypertension. The expression of the AT1aR mRNA and protein was not different between the SHRs and WKY rats at 4 weeks. However, they were significantly greater in SHRs than in WKY rats at 20 weeks. Bisulfite sequencing revealed that the AT1aR promoter from the aorta and mesenteric artery of the SHRs was progressively hypo-methylated with age as compared with their WKY rat counterparts. These results suggest that the heightened AT1aR expression in SHRs is related to the AT1aR promoter hypo-methylation, which might be a consequence of the increased blood pressure and may be important in the maintenance of high blood pressure.

Abstract
AIMS To synthesize silver-loaded mesoporous silica SBA-15 (Ag/SBA-15) materials and examine their antimicrobial action and antimicrobial mechanism. METHODS AND RESULTS Ag/SBA-15 materials were prepared by means of incipient wetness impregnation, impregnation and direct hydrothermal synthesis methods. The antimicrobial activity of Ag/SBA-15 was investigated using Escherichia coli as an indicator bacterium, and the antimicrobial mechanism was explored. The properties and Ag(+) release behaviour of Ag/SBA-15 materials were compared. Experimental results showed that Ag/SBA-15 materials resulted in 7·5 log inactivation of E. coli for only 60 min, which exhibited very high antimicrobial activities at room temperature without using any light or electrical power input. The cell wall and cell membrane were destroyed in the antimicrobial process, leading to leakage of intracellular components. The formation of extracellular reactive oxygen species (ROS) involved in the bactericidal process was confirmed. Production of intracellular ROS was also discovered. CONCLUSIONS Ag/SBA-15 exhibited high antimicrobial activity against E. coli. This antimicrobial effect was a synergistic action between extracellular ROS and the toxicity of Ag(+) , which induced intracellular ROS production and subsequent cell death. SIGNIFICANCE AND IMPACT OF THE STUDY This study revealed for the first time the antimicrobial activities and mechanisms of Ag/SBA-15 materials prepared with different methods.

Abstract
BACKGROUND Hypoxia/reoxygenation(H/R)-induced apoptosis of cardiomyocytes plays an important role in myocardial injury. Lycopene is a potent antioxidant carotenoid that has been shown to have protective properties on cardiovascular system. The aim of the present study is to investigate the potential for lycopene to protect the cardiomyocytes exposed to H/R. Moreover, the effect on mitochondrial function upon lycopene exposure was assessed. METHODS AND FINDINGS Primary cardiomyocytes were isolated from neonatal mouse and established an in vitro model of H/R which resembles ischemia/reperfusion in vivo. The pretreatment of cardiomyocytes with 5 µM lycopene significantly reduced the extent of apoptosis detected by TUNEL assays. To further study the mechanism underlying the benefits of lycopene, interactions between lycopene and the process of mitochondria-mediated apoptosis were examined. Lycopene pretreatment of cardiomyocytes suppressed the activation of the mitochondrial permeability transition pore (mPTP) by reducing the intracellular reactive oxygen species (ROS) levels and inhibiting the increase of malondialdehyde (MDA) levels caused by H/R. Moreover, the loss of mitochondrial membrane potential, a decline in cellular ATP levels, a reduction in the amount of cytochrome c translocated to the cytoplasm and caspase-3 activation were observed in lycopene-treated cultures. CONCLUSION The present results suggested that lycopene possesses great pharmacological potential in protecting against H/R-induced apoptosis. Importantly, the protective effects of lycopene may be attributed to its roles in improving mitochondrial function in H/R-treated cardiomyocytes.

Abstract
Abstract
Introduction: Breast-conserving surgery (BCS) followed by radiation therapy has proven to be as effective as modified radical mastectomy, and has, therefore, been considered as the standard treatment for patients with localized breast cancer in Western societies. However, performance of BCS for the treatment of breast cancer in China is not as common as in Western countries. This study was to evaluate healthy women's attitudes towards BCS in an urban region of China.Method: Between February and March 2009, three hundred and fifty healthy women from three urban suburbs of Taiyuan city in Northern China were invited to complete a self-administered questionnaire. Participants' characteristics, including age, education, occupation, and attitudes towards breast cancer treatment options and involvement of treatment decisions, were collected and analyzed.Results: Three hundred and fifteen women returned the questionnaire. The response rate was 90%. The median age of the participants was 31.2 years old (range: 16 – 69 years old). Among them, 49.2% were married, 27.9% had received high levels of education, and 87.3%, 95.2% and 71.4% would like to know the disease status, to involve making treatment decisions, and to accept BCS, respectively, if they were diagnosed with breast cancer. Women aged above 45 years were more likely to choose BCS compared with those less than 45 years old (73.4% vs 61.5%, P = 0.08). There was no association between choices of surgical approaches and levels of education or occupation. As for breast cancer treatment information sources, 76.8% of the participants mentioned oncologists, followed by the internet (12.1%), friends, and media (10.8%). Almost all responders (93.3%) would like to attend hospitals specialized in cancer treatment if breast lumps were detected.Conclusion: Although only 7.1% of breast cancer patients attending a specialized tumor hospital in Taiyuan city underwent BCS, the current study indicate that most women in Northern China would prefer BCS to mastectomy if they were diagnosed with breast cancer. Therefore, further occupational training is warranted for oncologists in China so that optimal treatments for patients with breast cancer can be carried out.

Abstract
Abstract
Introduction: The incidence rate of female breast cancer has increased rapidly over the past 20 years in China. It has become the leading cause of newly diagnosed cancer and a major cause of mortality among women in some large Chinese cities with higher socio-economic status. This was partly explained by the change of lifestyle and reproductive risk factors. However, little data exists on the extent to which the menstrual and reproductive factors with breast cancer risk have changed in other less developed Chinese cities.Method: One cross sectional study was conducted in urban region of Taiyuan of China from September 2008 to March 2009. One thousand and five hundreds healthy women were invited to complete a self-administered questionnaire. Participants' characteristics, including age, education, occupation, weight, height, age at menarche, age at first birth, parity, duration of breastfeeding, and age at menopause were collected and analyzed. Study subjects were divided into six groups: younger than or equal to 20, 21 to 30, 31 to 40, 41 to 50, 51 to 60 and older than 60 years old.Results: One thousand four hundreds and twenty eight women returned the questionnaire. The response rate was 95.2%. Median age of women in this study was 39 years old (range: 16 – 86 years old). There was a 4.8cm difference in the mean height between women born in 1990s and 1940s. The average age at menarche dropped from 16 years for women aged above 60 to 14.3 years for those younger than 20 years old. The average birth rate markedly decreased from 4.4 births per woman in the 1960s to 1.1 births per woman in the 1990s. The mean age at first birth increased 5.6 years through the period from the 1940s to 1980s. The breastfeeding time significantly reduced from 20.3 months to 3.6 months over 40 years.Conclusion: This study indicates that there has been significant change in the menstrual and reproductive factors associated with breast cancer risk in the last 40 years. These changes will certainly influence the incidence rate of breast cancer in the local city. Therefore, measures are needed to enhance the awareness of breast cancer and its early-detection methods among the urban region women in China.

Abstract
PURPOSE Non-steroidal anti-inflammatory drugs (NSAIDs) are used as analgesic in postoperative pain to reduce opioid side effects, such as drowsiness and nausea. However, NSAIDs have not been used extensively in cardiac surgical patients due to the fear of untoward effects on gastric, renal, and coagulation parameters. This study will evaluate the efficacy and safety of three NSAIDs for pain control in CABG patients. METHODS One hundred and twenty patients scheduled for elective CABG surgery were enrolled in randomized, double blind, controlled study. Standardized fast track cardiac anesthesia was used. One dose of drug (75 mg diclofenac, 100 mg ketoprofen, 100 mg indomethacin, or placebo) was given pr one hour before tracheal extubation and a second dose 12 hr later. Pain was treated with morphine iv and acetaminophen po. Visual analogue pain scores were recorded at baseline, 3, 6, 12 and 24 hr after the first dose of drug. RESULTS There were no differences among the groups in pain scores. Only patients who received diclofenac required less morphine than patients in the control group (P < 0.05). When the total amounts of pain medications were computed to morphine equivalents, only patients in the diclofenac group received less pain medications than the placebo group (P < 0.05). Proportion of patients with postoperative increase of creatinine level (20% and over) did not differ between placebo and drug groups. CONCLUSION Non-steroidal anti-inflammatory drugs may be used for analgesia management post CABG surgery in selected patients. Diclofenac appears to have the best analgesic effects by reducing the morphine and other analgesic requirement postoperatively.

Abstract
The activities of hybrid dimers of alkaline phosphatase containing two chemically modified subunits have been investigated. One hybrid species was prepared by dissociation and reconstitution of a mixture of two variants produced by chemical modification of the native enzyme with succinic anhydride and tetranitromethane, respectively. The succinyl-nitrotyrosyl hybrid was separated from the other members of the hybrid set by DEAE-Sephadex chromatography and then converted to a succinyl-aminotyrosyl hybrid by reduction of the modified tyrosine residues with sodium dithionite. A comparison of the activities of these two hybrids with the activities of the succinyl, nitrotyrosyl and aminotyrosyl derivatives has shown that either the subunits of alkaline phosphatase function independently or if the subunits turnover alternately in a reciprocating mechanism, then the intrinsic activity of each subunit must be strongly dependent on its partner subunit.
