Objective: To investigate the extent of the cross-reactivity of hybrid capture 2 (HC2) assay andevaluate the potential effect of cross-reactivity on the long-term risk for cervical cancer andprecancers. Methods: Based on the Shanxi Province Cervical Cancer Screening Study-I (SPOCCS-I)cohort from 2005 to 2014 in Shanxi, China, SPF10-line probe assay (LiPA) was performedin all 598 HC2 positive and 300 random-selected HC2 negative cervical specimens. Tenyearcumulative incidence rate (CIR) of cervical intraepithelial neoplasia grade 2 or worse(CIN2+) of these two tests was evaluated using Kaplan-Meier methods. Possible humanpapillomavirus (HPV) types to be cross-reacted by HC2 were also analyzed. Results: The overall agreement between HC2 and SPF10-LiPA for detecting carcinogenic HPVwas 73.27%. The highest 10-year cumulative risk of CIN2+ was observed in both HC2 positiveand LiPA-carcinogenic HPV positive women (25.70%; 95% confidence interval [CI]=23.55%–27.91%), followed by HC2 positive but LiPA-non-carcinogenic HPV positive women (9.97%;95% CI=8.57%–11.50%), HC2 negative but LiPA-carcinogenic HPV positive (2.56%; 95%CI=2.44%–2.70%) and HC2 positive but LiPA-HPV negative (1.85%; 95% CI=1.78%–1.92%)women. The proportion of cross-reactivity of HC2 with untargeted carcinogenic types was8.9%, most of which were attributable to HPV26, 73, 82, 69, 71, 53, 11, 43, and 54. Conclusion: The noticeable high risk of CIN2+ in women infected with cross-reacted noncarcinogenicHPV and low risk in those with miss-to-detective carcinogenic HPV supportedan overall good clinical performance of HC2 for a general cervical cancer screening.

Sepsis is a clinical syndrome with no effective protective or therapeutic treatments. Acacetin, a natural flavonoid compound, has anti-oxidative and anti-inflammatory effects which can potentially work to reduce sepsis. We investigated the potential protective effect of acacetin on sepsis-induced acute lung injury (ALI) ALI and dissect out the underlying mechanisms. Mice were divided into five groups: a sham group, a sepsis-induced ALI group, and three sepsis groups pre-treated with 20, 40, and 80 mg/kg body weight of acacetin. We found that acacetin significantly attenuated sepsis-induced ALI, in histological examinations and lung edema. Additionally, acacetin treatment decreased protein and inflammatory cytokine concentration and the number of infiltrated inflammatory cells in BALF compared with that in the non-treated sepsis mice. Pulmonary myeloperoxidase (MPO) activity was lower in the acacetin-pre-treated sepsis groups than in the sepsis group. The mechanism underlying the protective effect of acacetin on sepsis is related to the regulation of certain antioxidation genes, including inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), superoxide dismutases (SODs), and heme oxygenase 1 (HO-1).Taken together, our results indicate that acacetin pre-treatment inhibits sepsis-induced ALI through its anti-inflammatory and antioxidative activity, suggesting that acacetin may be a potential protective agent for sepsis-induced ALI.

Background: To investigate the effects of preemptive analgesia with parecoxib sodium on haemodynamics and plasma stress hormones in surgical patients with thyroid carcinoma. Materials and Methods: Fifty-seven patients with thyroid carcinoma who underwent thyroidectomy selectively in Laiwu Hospital Affiliated to Taishan Medical University and Binzhou People's Hospital were selected and randomly divided into three groups, 19 cases in each group. The control group was intravenously injected 0.9% sodium chloride injection before anesthesia induction; trial group I was intravenously injected with parecoxib sodium 20 min before anesthesia induction; based on trial group I, trial group II was injected with parecoxib sodium again 12 h after surgery. The levels of plasma norepinephrine (NE), cortisol (Cor) and blood glucose before, 12 and 24 h after surgery and changes of haemodynamics before surgery, at the end of surgery and 12, 24 and 48 h after surgery were compared in the three groups. Besides, visual analogue scale (VAS) scores were recorded 4, 8, 12 and 24 h after surgery. Results: 12 and 24 h after surgery, the levels of plasma NE and Cor in three groups rose dramatically (P<0.05 or (P<0.01); The levels of plasma NE and Cor in trial groups I and II were evidently lower than in control group (P<0.05 or P<0.01), and those in trial group II slightly lower than in trial group I. 12 h after surgery, the heart rates (HR) and systolic pressures (SBP) in trial groups I and II increased obviously by comparison to surgery before (P<0.05 or P<0.01), but gradually returned to the preoperative level. HR, SBP and diastolic pressures (DBP) in trial groups I and II at the end of surgery and 12 h after surgery were all lower than in the control group, and significant differences were present (P<0.05 or (P<0.01). At 4, 8, 12 and 24 h after surgery, VAS scores in trial groups I and II were markedly lower than in the control group (P<0.05 or (P<0.01), the scores in trial group II being the lowest. Conclusions: Combined application of parecoxib sodium for preemptive analgesia before anesthesia and after surgery can effectively reduce the levels of plasma stress hormones and improve analgesic effects in surgical patients with thyroid carcinoma, and without conspicuous impact on haemodynamics.

Purpose We sought to investigate the effectiveness and safety of dabrafenib in children with BRAFV600E-mutated Langerhans cell histiocytosis (LCH). Materials and Methods A retrospective analysis was performed on 20 children with BRAFV600E-mutated LCH who were treated with dabrafenib. Results The median age at which the patients started taking dabrafenib was 2.3 years old (range, 0.6 to 6.5 years). The ratio of boys to girls was 2.3:1. The median follow-up time was 30.8 months (range, 18.9 to 43.6 months). There were 14 patients (70%) in the risk organ (RO)+ group and six patients (30%) in the RO– group. All patients were initially treated with traditional chemotherapy and then shifted to targeted therapy due to poor control of LCH or intolerance to chemotherapy. The overall objective response rate and the overall disease control rate were 65% and 75%, respectively. During treatment, circulating levels of cell-free BRAFV600E (cfBRAFV600E) became negative in 60% of the patients within a median period of 3.0 months (range, 1.0 to 9.0 months). Grade 2 or 3 adverse effects occurred in five patients. Conclusion Some children with BRAFV600E-mutated LCH may benefit from monotherapy with dabrafenib, especially high-risk patients with concomitant hemophagocytic lymphohistiocytosis and intolerance to chemotherapy. The safety of dabrafenib is notable. A prospective study with a larger sample size is required to determine the optimal dosage and treatment duration.

The effects of erlotinib combined with celecoxib in a lung cancer xenograft model were here explored with a focus on possible mechanisms. A xenotransplanted lung cancer model was established in nude mice using the human lung cancer cell A549 cell line and animals demonstrating tumour growth were randomly divided into four groups: control, erlotinib, celecoxib and combined (erotinib and celecoxib). The tumor major axis and short diameter were measured twice a week and after 40 days tissues were collected for immunohistochemical analyses of Bcl-2 and Bax positive cells and Western-blotting analyses for the epidermal growth factor recepto (EGFR), P-EGFR, and cyclooxygenase-2 (COX-2). Tumor size in the combined group was smaller than in the others (p<0.01) and the percentage of Bcl-2 positive cells was fewer in most cases (p<0.01), while that of Bax positive cells was greater than in the erlotinib and celecoxib groups (P>0.05). Western blotting showed decreased expression of P-EGFR and COX-2 with both erlotinib and celecoxib treatments, but most pronouncedly in the combined group (P<0.05). Simultaneous blockage of the EGFR and COX-2 signal pathways exerted stronger growth effects in our human xenotransplanted lung cancer model than inhibition of either pathway alone. The anti-tumor effects were accompanied by synergetic inhibition of tumor cell apoptosis, activation of p-EGFR and expression of COX-2.

Objectives In the past centuries, the concept of “physical education” has changed from a more general concepts including physical activities and sports, to specifically inferring “instruction of physical activity”. Instead, “sports” has become the comprehensive concept of sports, exercise, and physical education. Given to the inconsistent terminologies and English translations of “體育 (ti-yu)” (physical education) and “運 動 (yun-dong)” (sports or exercise) in Mandarin, the purpose of this study was to investigate in the current terminology usage, hierarchy, and the English translation of “體育 (ti-yu)” and “運動 (yun-dong)” in Taiwan. Met hods Three government authorities, two sport related universities, eight top sport and exercise journals, and nighty-six college departments in Taiwan were analyzed. Results “運動 (yun-dong)” was the most widely used terminology as “體育 (ti-yu)” occupied the majority usage among government authorities, sport related universities, and title of top sport and exercise journals. Regarding English translation, despite of “department of physical education”, “sports” remained the most common terminology. Moreover, “體育 (ti-yu)” and “sports” are the highest hierarchy among government authorities, and sport related university; “體育 (ti-yu)” and “physical education” are the highest hierarchy among traditional sport and exercise journals; “運動 (yun-dong)” and “sports” are the highest hierarchy among college departments also the mainstream of current translation and hierarchy. Conclusions “體育 (ti-yu)” was the highest hierarchy in the past. However, “運動 (yun-dong)” has been the mainstream of the highest hierarchy in Mandarin according to college departments. In English, “sport(s)” is the main term in Taiwan when translating “體育 (ti-yu)” and 運動 (yun-dong)”, also being the highest hierarchy. On the other hand, “體育 (ti-yu)” and “physical education” are utilized regarding those departments focusing on educating PE teachers. This study expects the terminology, English translations, and hierarchy being align with the mainstream of current translation and hierarchy in the future.

Inhalational anthrax is caused by B. anthracis, a virulent spore- forming bacterium which secretes anthrax toxins consisting of protective antigen (PA), lethal factor (LF) and edema factor (EF). LF is a Zn-dependent metalloprotease and is the main determinant in the pathogenesis of anthrax. Here we report the identification of a lead small-molecule inhibitor of anthrax lethal factor by screening an available synthetic small-molecule inhibitor library using fluorescence-based high-throughput screening (HTS) approach. Seven small molecules were found to have inhibitory effect against LF activity, among which SM157 had the highest inhibitory activity. All theses small molecule inhibitors inhibited LF in a noncompetitive inhibition mode. SM157 and SM167 are from the same family, both having an identical group complex, which is predicted to insert into S1` pocket of LF. More potent small-molecule inhibitors could be developed by modifying SM157 based on this identical group complex. [BMB reports 2011; 44(12): 811-815]
