MicroRNA-506 has a suppressive effect on the tumorigenesis of nonsmall-cell lung cancer by regulating tubby-like protein 3.

MicroRNA-506 (miR-506), a miRNA, has been proven to act as a tumor suppressor gene in nonsmall-cell lung cancer (NSCLC); Tubby-like protein 3 (TULP3) is a potential target gene of miR-506. This study investigates whether miR-506 can prevent NSCLC progression by mediating TULP3. In vivo and in vitro experiments were performed to explore the function and potential regulatory relationship of miR-506 and TULP3 in NSCLC.

Theophylline and dexamethasone in combination reduce inflammation and prevent the decrease in HDAC2 expression seen in monocytes exposed to cigarette smoke extract.

Lung and systemic inflammation are associated with impaired lung function and increased mortality in patients with chronic obstructive pulmonary disease (COPD). Theophylline and glucocorticoids have been shown to have an anti-inflammatory effect in some respiratory diseases. However, corticosteroid insensitivity is a major barrier to the anti-inflammatory management of COPD.

Clinical study of lung-supplementing and stasis-dissolving decoction (Bufei Huayu Tang) combined with gefitnib for treatment of advanced non-small cell lung cancer.

To investigate the clinical efficacy and drug safety of Lung-Supplementing and Stasis-Dissolving Decoction (Bufei Huayu Tang) combined with gefitnib for treatment of advanced non-small cell lung cancer (NSCLC). Then, 80 patients with advanced NSCLC hospitalized in Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine were included, and were double-blindly randomized into 4 groups: control group (gefitinib alone 250mg, once daily), low-dose group (100mL/day), middle-dose group (150mL/day) and high-dose group (200mL/day) treated with different doses of Bufei Huayu Tang besides gefitinib. Clinical efficacy, life quality change before and after treatment, ECOG score, survival time and incidence of adverse drug reaction were compared.

[Study on the spectrum response of Brassica Campestris L leaf to the zinc pollution].

In the present paper, the spectrum response of Brassica Campestris L leaf to the stress of heavy metal zinc pollution was studied in three spectral rangess of the red edge position (680-740 nm), the visible spectrum (460-680 nm) and the near infrared spectrum (750-1000 nm). The results indicate that the Zn content in cabbage leaves increases and the chlorophyll level reduces with the increase in Zn concentration in soil. With the Zn content of Brassica Campestris L leaves increasing, the leaf spectral reflectivity in visible light (A1) and the range of red edge shift (S) ascends, the the leaf spectral reflectivity in the near infrared light (A2) decreases.
