Colorectal cancer's burden attributable to a diet high in processed meat in the Belt and Road Initiative countries.

Background: Colorectal cancer (CRC) plays a significant role in morbidity, mortality, and economic cost in the Belt and Road Initiative ("B and R") countries. In addition, these countries have a substantial consumption of processed meat. However, the burden and trend of CRC in relation to the consumption of a diet high in processed meat (DHPM-CRC) in these "B and R" countries remain unknown.

[Infrared radiative characteristic of Ho3+ in heavy metal tellurite glasses].

Ho3+ doped and Ho3+/Yb3+ co-doped low phonon heavy metal tellurite glasses with large refractive indices were designed and fabricated. Based on optical absorption, Judd-Ofelt parameters Omega2, Omega4 and Omega6 were derived to be 4.373 x 10(-20), 1.

[Spectral power distribution and quantum yield of Sm3+-doped bismuth tellurite glass under the excitation of violet LED].

A new method for measuring the spectral power distribution in Sm3+-doped bismuth tellurite glass with higher refractive index and lower phonon energy by using integrating sphere was introduced and designed for the first time. Fluorescence measurement system was constituted by integrating sphere of 10-inch diameter, which was connected to a DDC detector. A standard halogen lamp was used to calibrate the measurement system and the auxiliary standard halogen lamp was employed for collating inner change in integrating sphere.

An open-label, randomized comparison of levofloxacin and amoxicillin/clavulanate plus clarithromycin for the treatment of hospitalized patients with community-acquired pneumonia.

Background: Anti-pneumococcal fluoroquinolone has been used to treat community-acquired pneumonia (CAP) frequently because of its broad antimicrobial spectrum.

Methods: This randomized, open-label study was conducted in a tertiary teaching hospital. Eligible patients were randomized to levofloxacin 500 mg IV q24h followed by 500 mg orally q24h or a combination of amoxicillin/clavulanate 500 mg/100 mg IV q8h with oral clarithromycin 500 mg q12h and then oral amoxicillin/clavulanate 250 mg/125 mg q8h with oral clarithromycin 500 mg q12h for 7-14 days.

[Growth inhibitory effects of lipofectamine-mediated DCC gene on ovarian epithelial carcinoma].

Objective: To study the inhibitory effects of lipofectamine-mediated deleted colorectal carcinoma gene on ovarian epithelial carcinoma (ovarian cancer) cell line SKOV3.

Methods: We constructed a recombinant eukaryotic expression vector pcDNA3.1 (+)-DCC containing exogenous human DCC cDNA and vector with neomycin resistance gene, which were introduced by lipofectamine-mediated gene transfection into SKOV3 cell line that does not express DCC endogenously, thus forming SKOV3/DCC.
