Abstract
The β2‑adrenergic receptor (β2‑AR, encoded by the ADRB2 gene) is a member of the G‑protein‑coupled receptor superfamily that can be stimulated by catecholamines. Studies in vivo and in vitro have confirmed that β‑blockers (β‑AR antagonists) exert antitumor effects on various tumors. Furthermore, ADRB2 single‑nucleotide polymorphisms (SNPs) have been identified to alter the expression and conformation of β2‑AR, which may alter the β‑blocker drug response. The aim of the present study was to investigate the effect of β‑blockers on triple‑negative breast cancer cells and determine whether ADRB2 SNPs affect the response to β‑blocker drugs. Propranolol and ICI 118,551 significantly inhibited the viability of MDA‑MB‑231 cells, arrested cell cycle progression at G0/G1 and S phase and induced cell apoptosis. Western blot analysis indicated that the phosphorylation levels of extracellular‑signal‑regulated kinase (ERK)1/2 and the expression levels of cyclo‑oxygenase 2 (COX‑2) were significantly decreased following β‑blocker treatment. Four haplotypes, which comprised ADRB2 SNPs rs1042713 and rs1042714, were transfected into 293 cells. After 24 and 48 h of transfection, ADRB2 mRNA expression was significantly decreased in mutant groups compared with the wild‑type group. The ADRB2 SNPs exerted no effect on cell viability, but did affect the drug response of ICI 118,551. Furthermore, ADRB2 SNPs also affected the regulatory function of ICI 118,551 on the ERK/COX‑2 signaling pathway. Collectively, propranolol and ICI 118,551 inhibited the viability of MDA‑MB‑231 cells by downregulating the ERK/COX‑2 signaling pathway and inducing apoptosis. The results of the present study indicated that SNPs rs1042713 and rs1042714 of ADRB2 affected the response to ICI 118,551, and the underlying molecular mechanism was elucidated.

Abstract
Aim: The clinical efficacy of valproic acid (VPA) varies greatly among epileptic patients. To find the potential genetic factors related to VPA responses, the pharmacogenetics study was conducted. Methods: Two hundred and one Chinese Han epileptic patients who were treated by VPA for at least 1 year were recruited. Up to 24 SNPs in 11 candidate genes that correlate with the metabolism, transport or target of VPA were genotyped. Results: Three SNPs, rs1731017 (ABAT), rs2304016 (SCN2A) and rs1054899 (ALDH5A1) were found associated with VPA responses with the p-values of 0.003, 0.007 and 0.048, respectively. Further interaction analysis showed that the interaction between rs17183814 (ABAT) and rs1641022 (SCN2A) was also correlated with the response of VPA (p = 0.006). Conclusion: This study found three SNPs and one interaction among ABAT, SCN2A and ALDH5A1 were significantly associated with VPA response, which indicated that these genes may play important roles in the pharmacological mechanism of VPA.

Abstract
β-ARs are extensively spread in different tissues of our body, which could be activated by neurotransmitters norepinephrine and epinephrine to mediate physiological function and abnormal states including cancer. Recently, β-AR blockers could have significant implications in cancer therapy. But the precise molecular mechanisms are far from being fully understood. Through identifying the β-AR system signal pathways relevant to cancer, we can understand the mechanisms of β-blockers used for cancer treatment. What's more, retrospective clinical data made β-blockers jump out of the traditional field of cardiovascular disease and strengthened our confidence in cancer therapy. At last, genetic studies of β-adrenergic system offered crucial genes to analyze the effects of polymorphisms on cancer susceptibility, therapy response and prognosis of cancer patients.

Abstract
We demonstrate the formation of a two-dimensional electron gas (2DEG) at the (100) surface of the 5d transition-metal oxide KTaO3. From angle-resolved photoemission, we find that quantum confinement lifts the orbital degeneracy of the bulk band structure and leads to a 2DEG composed of ladders of subband states of both light and heavy carriers. Despite the strong spin-orbit coupling, our measurements provide a direct upper bound for the potential Rashba spin splitting of only Δk(parallel)}~0.02 Å(-1) at the Fermi level. The polar nature of the KTaO3(100) surface appears to help mediate the formation of the 2DEG as compared to nonpolar SrTiO3(100).

Abstract
Many-body interactions in transition-metal oxides give rise to a wide range of functional properties, such as high-temperature superconductivity, colossal magnetoresistance or multiferroicity . The seminal recent discovery of a two-dimensional electron gas (2DEG) at the interface of the insulating oxides LaAlO(3) and SrTiO(3) (ref. 4) represents an important milestone towards exploiting such properties in all-oxide devices. This conducting interface shows a number of appealing properties, including a high electron mobility, superconductivity and large magnetoresistance, and can be patterned on the few-nanometre length scale. However, the microscopic origin of the interface 2DEG is poorly understood. Here, we show that a similar 2DEG, with an electron density as large as 8×10(13) cm(-2), can be formed at the bare SrTiO(3) surface. Furthermore, we find that the 2DEG density can be controlled through exposure of the surface to intense ultraviolet light. Subsequent angle-resolved photoemission spectroscopy measurements reveal an unusual coexistence of a light quasiparticle mass and signatures of strong many-body interactions.

Abstract
The charge density wave (CDW) is usually associated with Fermi surfaces nesting. We here report a new CDW mechanism discovered in a 2H-structured transition metal dichalcogenide, where the two essential ingredients of the CDW are realized in very anomalous ways due to the strong-coupling nature of the electronic structure. Namely, the CDW gap is only partially open, and charge density wave vector match is fulfilled through participation of states of the large Fermi patch, while the straight Fermi surface sections have secondary or negligible contributions.

Abstract
The body-centered-cubic (bcc) phase of Ni, which does not exist in nature, has been achieved as a thin film on GaAs(001) at 170 K via molecular beam epitaxy. The bcc Ni is ferromagnetic with a Curie temperature of 456 K and possesses a magnetic moment of 0.52+/-0.08 micro(B)/atom. The cubic magnetocrystalline anisotropy of bcc Ni is determined to be +4.0x10(5) ergs x cm(-3), as opposed to -5.7x10(4) ergs x cm(-3) for the naturally occurring face-centered-cubic (fcc) Ni. This sharp contrast in the magnetic anisotropy is attributed to the different electronic band structures between bcc Ni and fcc Ni, which are determined using angle-resolved photoemission with synchrotron radiation.

Abstract
A polymerase chain reaction (PCR) method was established for the detection of gonococcal gene in samples obtained from women and children with lower genital tract infection. The primers were used for PCR amplification derived from sequence for DNA representing part of the open reading frame (ORF) for the chromosome of N. gonorrhoea. In this study, a total number of 9204 specimens were obtained from women and children with lower genital tract infection from 1986 to 1995 in Taiyuan. The positive rate of N. gonorrhoea for Gram's stain of smears was 26.5% while the rates for culture and PCR were 12.4% and 21.0%, respectively. The results showed that PCR test was simple, rapid sensitive and specific for the detection of gonococcal gene in clinical specimens.

Abstract
In this study, we have measured plasma glucose and insulin levels at fasting and following an oral glucose load (75g) in 39 non-diabetic subjects (22 untreated hypertensive, 17 normotensive subjects). We also assessed plasma cholesterol (Ch), triglyceride (TG) levels and Na(+)-K(+)-pump activity in the membranes of their erythrocytes. Overall, hypertensive subjects have hypercholesterol, hypertriglyceride, glucose intolerance and hyperinsulinemia. These changes accorded with Syndrome X proposed by Reaven. In multivariant analysis, after correcting for age, BMI, diastolic pressure (DBP) was positively related to fasting, 1/2h insulin and insulin area under cure (AUC) (P < 0.05). Both systolic pressure (SBP) and DBP were negatively correlated to Na(+)-K(+)-pump (P < 0.01, 0.001), while Na(+)-K(+)-pump was negatively fasting, 1/2h, 1h, 2h insulin levels and insulin AUC (P < 0.05, 0.05, 0.01, 0.01, respectively). These results showed that insulin may affect Na(+)-K(+)-pump activity to develop hypertension independent of age and obese. We also postulated that insulin resistance was causal in the syndrome X, also one of factors developing coronary artery disease.
