Meta Analysis Comparative Study
A meta-analysis of pemetrexed-based doublet compared with pemetrexed alone for the second-line treatment of advanced non-small-cell lung cancer.
This meta-analysis investigated pemetrexed-based doublet compared with pemetrexed alone as second-line therapy for patients with advanced non-small cell lung cancer. ⋯ This is the first meta-analysis to compare pemetrexed-based doublet with single-agent pemetrexed in second-line therapy of non-small cell lung cancer. Our meta-analysis suggested that pemetrexed combination chemotherapy was not superior to single-agent arm and was not recommended as the second-line chemotherapy for patients with non-small cell lung cancer (Tab. 2, Fig. 6, Ref. 20).

To discuss the relationship between the acute cerebral infarction of differently aged population and the variable number tandem repeat polymorphism of endothelial nitric oxide synthase (eNOS) gene. ⋯ The ab genotype of eNOS 4th intron is correlated with the acute cerebral infarction of young and middle-aged Chinese Han population that may involve allelic gene a as an independent risk factor (Tab. 3, Fig. 3, Ref. 13).

Recent reports demonstrated that levosimendan improved post-resuscitation myocardial function in rat and pig models. ⋯ In this rabbit model of bupivacaine-induced cardiac arrest, resuscitation with combined iv lipid emulsion and levosimendan was more efficacious than lipid alone (Tab. 3, Ref. 24).

Comparative Study
Ultrasound monitoring of the treatment of clinically significant knee osteoarthritis.
The study presented an ultrasound (US) monitoring of treatment as a new imaging US method with the results of therapy of clinically significant knee osteoarthritis. ⋯ We demonstrated a new method - US monitoring of therapy, which can objectivize the efficiency of treatment of clinically significant knee osteoarthritis. We would recommend US monitoring of therapy for the routine use in orthopedic clinical praxis (Tab. 6, Graph 3, Fig. 3, Ref. 15).

Comparative Study
COX-2, p16 and Ki67 expression in DCIS, microinvasive and early invasive breast carcinoma with extensive intraductal component.
Recent studies have showed a significant association between the combination of COX-2, p16 and Ki67 overexpression and incidence of subsequent invasive carcinoma in a subgroup of treated ductal carcinoma in situ (DCIS) and the indicated prognostic value of COX-2, p16 and Ki67 in early breast cancer. Based on the continual model of carcinogenesis and the mentioned results, we hypothesize, that if COX-2, p16 and Ki67 expression is prognostic for DCIS future behaviour, the expression level of the markers correlates also with different stages of breast carcinomas such as DCIS, microinvasive cancer and early invasive cancer with an extensive intraductal compound. The aim of this study was to compare the expression of COX-2, p16 and Ki67 in different stages of breast carcinoma such as pure DCIS, microinvasive cancer (T1mic) and invasive ductal carcinoma with an extensive intraductal component (IDC with EIC). The expression was assessed only in in situ component of the three subgroups (DCIS, T1mic, EIC) in order to show a possible correlation of COX-2, p16 and Ki67 with different stages of carcinogenesis. ⋯ This is the first published study ever assessing the expression of COX-2, p16 and Ki67 markers in different breast tumors containing DCIS compound. Our results showed an increasing expression pattern of COX-2 and p16 with the rising severity of the diagnosis (expression was measured exclusively in in situ lesions within tumors containing different extant of invasiveness). The same relationship was showed for p16 marker alone. These data support different expression pattern of COX-2 and p16 markers in combination and p16 marker alone in "in situ lesions" according to the stage of carcinogenesis. This fact might be useful in the evaluation of further behaviour of early breast tumors (Tab. 3, Fig. 8, Ref. 29).
