Meta AnalysisExcision repair cross complementation group 1 polymorphisms and lung cancer risk: a meta-analysis.
Several studies have evaluated the association between polymorphisms of encoding excision repair cross complementation group 1 (ERCC1) enzyme and lung cancer risk in diverse populations but with conflicting results. By pooling the relatively small samples in each study, it is possible to perform a meta-analysis of the evidence by rigorous methods. ⋯ We found little evidence of an association between the T1900C or C8092A polymorphisms of ERCC 1 and the risk of lung cancer in Caucasian or Han Chinese people.

Review Meta AnalysisHeterosexual risk of HIV infection in China: systematic review and meta-analysis.
Heterosexual sex has become the dominant transmission route in China. Recently studies reported high heterogeneity in heterosexual transmission risk in resource-limited countries. The aim of this study was to summarize the risk of HIV transmission among Chinese serodiscordant couples. ⋯ Transmission estimates in China were lower than other developing countries, but higher than developed countries. Research that better defines HIV secondary transmission rates and the associated behavioral, treatment adherence, and health-related risk factors among heterosexual serodiscordant couples in China is needed.

Meta AnalysisIrinotecan or oxaliplatin combined with 5-fluorouracil and leucovorin as first-line therapy for advanced colorectal cancer: a meta-analysis.
To compare clinical efficacy and toxicity of irinotecan combined with 5-fluorouracil and leucovorin with those of oxaliplatin combined with 5-fluorouracil and leucovorin as first-line therapy for advanced colorectal cancer. ⋯ Both irinotecan and oxaliplatin combined with 5-fluorouracil and leucovorin were effective in the first-line therapy of advanced colorectal cancer. However, the combined regimen of oxaliplatin plus 5-fluorouracil and leucovorin is more excellent. Irinotecan tended to result in more gastrointestinal tract reactions than oxaliplatin did, but the myelosuppression and neurotoxicity were more frequent in oxaliplatin regimen than irinotecan regimen.

Meta AnalysisEffect of anterior cruciate ligament reconstruction on biomechanical features of knee in level walking: a meta-analysis.
The anterior cruciate ligament (ACL) is one of the most commonly injured knee ligaments. Even following ACL reconstruction, significant articular cartilage degeneration can be observed and most patients suffer from premature osteoarthritis. Articular cartilage degeneration and osteoarthritis development after ACL injury are regarded as progressive process that are affected by cyclic loading during frequently performed low-intensity daily activities. The purpose of this study was to perform a meta analysis on studies assessing the effects of ACL reconstruction on kinematics, kinetics and proprioception of knee during level walking. ⋯ Step length, walking speed, maximum knee flexion angle during loading response, joint position sense and threshold to detect passive motion usually observed with ACL deficiency were restored after the ACL reconstruction and rehabilitation, but no significant improvements were observed for peak knee flexion angle, maximum angular knee flexion excursion during stance, peak knee flexion moment during walking and maximum external tibial rotation angle throughout the gait cycle.

Meta AnalysisClinical and genetic study of spinocerebellar ataxia type 7 in East Asian population.
Spinocerebellar ataxia type 7 (SCA7) is known as an autosomal dominant cerebellar ataxia; patients with genetically confirmed diagnoses of SCA7 have increased rapidly in recent years. However, SCA7 is a rare subtype of SCA, and most data available about SCA7 are those of white people. The aim of the present study was to systematically review the prevalence and clinical and genetic aspects of SCA7 patients in East Asian population. ⋯ The prevalence of SCA7 in SCA patients, the age at onset and CAG repeats of SCA7 patients in East Asia are consistent with those of white people. However, larger population study is needed to assess the correlation between the CAG repeat size and initial symptoms of SCA7 patients in East Asia.
