[Evaluation of induction chemotherapy with vinorelbine plus cisplatin (NP) or docetaxel plus cisplatin (TP) combined with concurrent chemoradiotherapy for patients with locally advanced nasopharyngeal carcinoma].

Objective: To compare the efficacy and side effects of induction chemotherapy with vinorelbine plus cisplatin (NP) or docetaxel plus cisplatin (TP) combined with concurrent chemoradiotherapy in treating locally advanced nasopharyngeal carcinoma (NPC).

Methods: From January 2005 to December 2009, 146 patients with locally advanced nasopharyngeal carcinoma treated in our department were randomized into NP group (76 patients) or TP group (70 patients). Both groups received two cycles of induction chemotherapy and concurrent chemoradiotherapy.

A visual detection of protein content based on titration of moving reaction boundary electrophoresis.

A visual electrophoretic titration method was firstly developed from the concept of moving reaction boundary (MRB) for protein content analysis. In the developed method, when the voltage was applied, the hydroxide ions in the cathodic vessel moved towards the anode, and neutralized the carboxyl groups of protein immobilized via highly cross-linked polyacrylamide gel (PAG), generating a MRB between the alkali and the immobilized protein. The boundary moving velocity (V(MRB)) was as a function of protein content, and an acid-base indicator was used to denote the boundary displacement.

Fast and selective determination of total protein in milk powder via titration of moving reaction boundary electrophoresis.

In this paper, moving reaction boundary titration (MRBT) was developed for rapid and accurate quantification of total protein in infant milk powder, from the concept of moving reaction boundary (MRB) electrophoresis. In the method, the MRB was formed by the hydroxide ions and the acidic residues of milk proteins immobilized via cross-linked polyacrylamide gel (PAG), an acid-base indicator was used to denote the boundary motion. As a proof of concept, we chose five brands of infant milk powders to study the feasibility of MRBT method.

Combination chemotherapy with paclitaxel, cisplatin and fluorouracil for patients with advanced and metastatic gastric or esophagogastric junction adenocarcinoma: a multicenter prospective study.

Objective: To evaluate the efficacy and toxicity of the combination regimen of paclitaxel, cisplatin and 5-FU (PCF) as first-line or second-line therapy in patients with advanced gastric and esophagogastric junction (EGJ) adenocarcinoma in China.

Methods: The patients were treated with paclitaxel 150 mg/m(2) on d1; fractionated cisplatin 15 mg/m(2) and continuous infusion 5-FU 600 mg/(m(2)·d) intravenously on d1-d5 of a 21-d cycle until disease progression or unacceptable toxicities.

Results: Seventy-five patients have been enrolled, among which, 41 received PCF regimen as the first-line therapy (group A) and 34 received the regimen as the second-line therapy (group B) with the median age of 59 years old and Karnofsky performance status (KPS) score ≥80.

[Epidemiological survey of rheumatic heart disease in schoolchildren in Guangdong and Xinjiang].

Objective: To investigate the prevalence of rheumatic heart disease (RHD) among schoolchildren in Guangdong Province and Xinjiang Uygur Autonomous Region.

Methods: Using a cluster sampling method, an epidemiological survey of RHD was conducted in 16 682 primary and high school students by auscultation in Guangdong Province and Xinjiang Uygur Autonomous Region from 2005 to 2006. Review of the clinical records, RHD survey in adults, and examination of the positivity rate of group A beta-hemolytic Streptococcus (GAS) by throat swab cultures in the students aged between 9 and 12 years in the sampled schools were also carried out.
