Role of epidermal growth factor receptor in lung cancer and targeted therapies.

Lung cancer is the foremost cause of cancer-related deaths world-wide. Both, the major forms of lung cancer, Non-small cell lung cancer (NSCLC) and Small cell lung cancers (SCLC), have responded effectively to chemo-, radiation and adjuvant-therapies. Tumor removal through surgery also appeared as a good therapeutic strategy.

Effect of intraoperative glucose fluctuation and postoperative IL-6, TNF-α, CRP levels on the short-term prognosis of patients with intracranial supratentorial neoplasms.

Objective: To investigate the effect of intraoperative glucose fluctuation and postoperative interlukin-6 (IL-6), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP) levels on the short-term prognosis of patients with intracranial supratentorial neoplasms.

Materials And Methods: Eighty-six patients undergoing intracranial excision were selected in The Second Hospital of Jilin University. According to the condition of glucose fluctuation, the patients were divided into group A (glucose fluctuation <2.

Influence of propofol, isoflurane and enflurance on levels of serum interleukin-8 and interleukin-10 in cancer patients.

Objective: To observe the influence of propofol, isoflurane and enflurance on interleukin-8 (IL-8) and IL-10 levels in cancer patients.

Methods: Ninety cancer patients with selective operation from March 2011 to May 2014 were randomly divided into group A (34 cases), group B (28 cases) and group C (28 cases). Intramuscular injections of scopine hydrochloride and phenobarbital sodium were routinely conducted to 3 groups.

[Resonance raman spectra of linear polymer molecule].

The present paper summarizes the characteristics of resonance Raman spectra of the linear polymer molecule, and its relations with the molecular structure, including: electronic spectra(ultraviolet-visible absorption spectrum), Raman spectra characteristics and its relations with external field; Modulation relation between the electron energy gap and CC atom vibration; Several experimental results were obtained: The UV-visible absorption spectra are red-shifted with decreasing temperature, increasing solvent density and reducing solution concentration, and because the linear polymer molecule has high structured order, decreasing pi electron energy gap; extended pi electronic delocalization, large effective conjugation length, large intensity of the Raman activity, Ramrnan spectrum are red-shifted, with large scattering cross section. "Am plitude modes" are the ideal theory models to study the linear polymer molecule.

[Meta analysis on the association between parental 5,10-methylenetetrahydrofolate reductase C677T polymorphism and the neural tube defects of their offspring].

Objective: To explore the relationship between 5,10-methylenetetrahydrofolate reductase gene polymorphism of the parents and the susceptibility to their offspring having neural tube defects. To forecast and evaluate the onset risk of neural tube defects (NTDs) on the basis of 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism on parents of the patients.

Methods: Electronic search strategy was carried out among the five databases from home and abroad to collect qualified research papers, according to the inclusion and exclusion criteria.

[The effect of pressure on binary solution phase transition and fermi resonance--comparing pressure effect for binary solution and pure liquid].

The Raman spectra of binary solution (CCl4 and C6 H6) and pure liquid were measured up to pressures of 11 GPa. The results show that pressure effect on binary solution is different from that on pure liquid: When mixing two liquids, owing to the changes in the density of the solution, intermolecular distance decreases and interaction energy increases, the frequency shift (blue shift) of spectral bands increases, and the frequency shift of binary liquid is faster than pure liquid frequency shift. Phase transitions (spectral bands splitting) change earlier and natural frequency difference delta0 increases with increasing pressure, while the Fermi resonance bands nu1 + nu6 and nu8 of benzene and nu1 + nu4 and nu3 of CCl4 disappear as the pressure decreases gradually, the spectral bands with different compressibility have different speed, whereas CCl4 has smaller density, longer bond, smaller force constant and larger compressibility and is easy to compress, C6H6 has larger density, smaller bond, larger force constant, smaller compressibility and is hard to compress.

Molecular spring washers: Raman scattering studies on Tpp J-aggregates under high pressure.

High-pressure Raman scattering studies at ambient temperature are performed on Tpp J-aggregates up to 13 GPa. It can be concluded that all the vibrational frequencies upshift linearly with increasing pressure which indicate that no obvious phase transition occurs during compression. In particular, the fact that the relative intensity of phenyl psi3 C-C in-plane stretching vibration shows monotonic enhancement with pressure future indicates that the dihedral angle between the porphyrin ring and phenyl groups decreases with increasing pressure.

[Serum levels of homocysteine and folate in neonates with asphyxia].

Objective: To determine whether serum homocysteine and folate levels are correlated with the occurrence of neonatal asphyxia and to study the effects of gender and gestational age on serum homocysteine and folate levels.

Methods: Thirty-five neonates with mild asphyxia (19 males and 16 females) and 40 normal neonates (control group,18 males and 22 females) were enrolled in this study. The asphyxia and the control groups consisted of 10 and 11 cases of preterm infants respectively.

[Optic neurotomy for central retinal vein occlusion].

Objective: To investigate the surgical effect and complication of optic neurotomy for ischemic central retinal vein occlusion (CRVO).

Methods: Eight patients elected to undergo optic neurotomy, The age range was 32 - 67 years, Five of the 8 were women and three were men. The duration of the CRVO were 3 - 8 months.
