Crizotinib, the first clinically designed and synthesized as a tyrosine kinase inhibitor targeting mesenchymal–epithelial transition factor, indicating marked anticancer activity in patients with advanced, anaplastic lymphoma kinase-positive non-small-cell lung cancer, was approved by the US Food and Drug Administration in 2011. In this review, we focus on the efficacy of crizotinib compared with chemotherapy in advanced anaplastic lymphoma kinase-positive lung cancer and present the role of crizotinib as a personalized alternative in previously treated patients with non-small-cell lung cancer. © 2015 Guo et al.

Objective: To compare the platelet to lymphocyte ratio (PLR) in normal people, benign prostatic hyperplasia (BPH) patients and prostate cancer (PCA) patients, and to explore the prognostic role of PLR in PCA. Methods: 155 normal people, 168 BPH patients and 103 PCA patients were enrolled. PCA patients were divided into PLR low value group (PLR<150) and PLR high value group (PLR≥150), and the difference of patients’ clinical characteristics between high value group and low value group was comparative studied.Results: The differences of PLR among normal people, BPH patients and PCA patients were statistically significant. In addition, platelet counts, neutrophil counts, PSA level, LDH level, AKP level, CRP level and alkaline phosphatase level were also significantly increased in PLR high value group, while the hemoglobin level was decreased. Besides, serious events such as coma during hospitalization were also more likely to appear in PLR high value group. PCA patients had an average follow-up of 3 years, and a total of 25 cases of patients died, including 11 (16.4%) cases in the PLR low value group, and 14 (38.9%) cases in PLR high value group with. Three years survival rate of patients in high value group was significantly reduced. Additionally, PLR was a possible risk factor associated with mortality, and an independent predictor of all-cause mortality during follow-up. Conclusion: PLR is significantly increased in PCA patients, and it is an independent predictor of 3-year mortality in PCA patients. © 2015, E-Century Publishing Corporation. All rights reserved.

Early postnatal propofol administration has potential detrimental effects on hippocampal synaptic development and memory. Therapeutic method is still lack due to unknown mechanisms. In this study, a 7-day propofol protocol was applied to model anesthesia in neonatal mice. Phosphatase and tensin homolog deleted on chromosome ten (Pten) inhibitor bisperoxovanadium (bpV) was pre-applied before propofol to study its potential protection. After propofol application, Pten level increased while phospho-AKT (p-AKT) (Ser473) decreased in dorsal hippocampus. Interestingly, i.p. injection of Pten inhibitor reversed the decrease of p-AKT. Two months after administration, basal synaptic transmission, hippocampal long-term potentiation (LTP) and long-term memory were reduced in propofol-administrated mice. By contrast, i.p. injection of Pten inhibitor at a dose of 0.2 mg/kg/day before propofol reversed the detrimental effects due to propofol application. Consistently, bpV injection also reversed propofol application-induced decrease of synaptic plasticity-related proteins, including p-CamKIIα, p-PKA and postsynaptic density protein 95. Taken together, our results demonstrate that bpV injection could reverse early propofol exposure-induced decrease of memory and hippocampal LTP. bpV might be a potential therapeutic for memory impairment after early propofol postnatal application. © 2015, Springer Science+Business Media New York.

Background: The combination of stent insertion and single high-dose brachytherapy is a feasible and safe palliative treatment regimen in patients with unresectable oesophageal cancer. We aimed to further assess the efficacy of this treatment strategy compared to a conventional covered stent in patients with dysphagia caused by unresectable oesophageal cancer. Methods: In this multicentre, single-blind, randomised, phase 3 trial, we enrolled patients with unresectable oesophageal cancer from 16 hospitals in China. We included adult patients (aged ≥20 years) with progressive dysphagia, unresectable tumours due to extensive lesions, metastases, or poor medical condition, and with clear consciousness, cooperation, and an Eastern Cooperative Oncology Group (ECOG) performance status score of 0-3. Eligible patients were randomly assigned (in 1:1 ratio, no stratification) to receive either a stent loaded with 125iodine radioactive seeds (irradiation group) or a conventional oesophageal stent (control group). The primary endpoint was overall survival. Survival analyses were done in a modified intention-to-treat group. This study is registered with ClinicalTrials.gov, number NCT01054274. Findings: Between Nov 1, 2009, and Oct 31, 2012, 160 patients were randomly assigned to receive treatment with either an irradiation stent (n=80) or a conventional stent (n=80). During a median follow-up of 138 days (IQR 72-207), 148 stents (73 in the irradiation group and 75 in the control group) were successfully placed into the diseased oesophagus in 148 participants. Median overall survival was 177 days (95% CI 153-201) in the irradiation group versus 147 days (124-170) in the control group (p=0·0046). Major complications and side-effects of the treatment were severe chest pain (17 [23%] of 73 patients in the irradiation group vs 15 [20%] of 75 patents in the control group), fistula formation (six [8%] vs five [7%]), aspiration pneumonia (11 [15%] vs 14 [19%]), haemorrhage (five [7%] vs five [7%]), and recurrent dysphagia (21 [28%] vs 20 [27%]). Interpretation: In patients with unresectable oesophageal cancer, the insertion of an oesophageal stent loaded with 125iodine seeds prolonged survival when compared with the insertion of a conventional covered self-expandable metallic stent.

Aims: Virtual touch tissue quantification (VTTQ) has been widely used in adults, but its application in fetuses has not been reported. The purposes of this study were to describe the normal shear wave velocity (SWV) values of fetal brain, lung, and liver by VTTQ and to examine the clinical usefulness of this procedure in evaluation of gestational age-related SWV changes in the fetal brain, lung and liver. Material and methods: One hundred fetuses were enrolled in this study and were evaluated at 18 weeks (second trimester) and 35 weeks (third trimester) during pregnancy. The SWV was measured at the cerebral parenchyma, thalamus, cerebellum, choroid plexus, left lung, right lung, right and left lobe of the liver in each participant. Results: The SWV at the cerebral parenchyma were all significantly greater in the third trimesters than in the second trimesters (3.29±1.05 vs. 2.22±0.97 m/s, p<0.001), while the velocities at thalamus, cerebellum, choroid plexus, left lung, right lung, right lobe of the liver and left lobe of the liver did not differ between the second and the third trimesters (p>0.05). Moreover, the SWV at the cerebral parenchyma correlated significantly with gestational age (r=0.47, p<0.001). Conclusions: VTTQ can provide numerical measurements of fetal brain, lung and liver stiffness and can effectively and objectively indicate gestational age-related changes in cerebral parenchyma stiffness by measuring SWV values.
