Meta Analysis
Clinical efficacy and safety of stem cell therapy for knee osteoarthritis: A meta-analysis.
We performed a meta-analysis of the efficacy and safety of stem cell therapy as a clinical treatment of knee osteoarthritis. This meta-analysis is expected to provide evidence of the efficacy of stem cell therapy, which is currently controversial, as a conservative treatment for knee osteoarthritis. ⋯ Stem cell therapy is certainly superior to traditional treatments in the conservative treatment of KOA; it considerably reduces pain with no obvious additional side effects.

Insulin dependent diabetes mellitus (IDDM) is a kind of heterogeneous disease caused by the interaction of polygene inheritance and environmental factors. The LMP2 and LMP7 are 2 loci in LMP gene, and although genetic association between LMP2 and LMP7 polymorphisms were reported, the results are inconclusive. The aim of this study was to investigate the association between LMP2 and LMP7 polymorphisms and IDDM risk. ⋯ The dominant model of LMP2 CfoI might be a risk factor for IDDM in Asian population. Whereas, the allelic and dominant models of LMP7 G37360T might be protective factors for IDDM in Caucasian population.

Although the early detection and treatment of non-metastatic esophageal cancer has improved, these patients' prognoses are still poor. Most patients with radical treatment for esophageal cancer will relapse in 3 years, and the best treatment strategy after recurrence has not been uniformly accepted. Multiform treatments may be beneficial to recurrent patients. ⋯ The emergence of ICIs promotes the treatment of esophageal cancer to a new era. Our observations suggest that patients for whom schedule to receive anti-programmed cell death protein-1 (anti-PD-1)/programmed cell death-ligand 1 (PD-L1) immunotherapy may require genomic testing to predict whether tumors respond to ICIs. In this case, we also present the predictors for the efficacy of targeted immunotherapy. At present, no matter which predictor of PD-L1 expression, tumor mutational burden (TMB), microsatellite instability (MSI), and tumor-infiltrating lymphocyte (TIL), a single predictor may be unconvincing and cannot accurately estimate the efficacy of immunotherapy. Multiplex detecting methods and combined biomarkers may provide new strategies. Consensus need to be reached in order to be widely applied in future studies.

Breast cancer susceptibility gene 1/2 (BRCA1/2) is a promising tumor marker in many types of cancer. However, the methylation frequency of BRCA1/2 gene with occurrence risk and survival benefit of patients with breast carcinoma remains controversy. The aim of the present study was to assess the relationship between BRCA1/2 gene promoter methylation and the occurrence and prognosis in breast carcinoma based on a meta-analysis, meanwhile, this article explored the differential expression levels of BRCA1/2 gene promoter methylation in peripheral blood and tumor tissues of breast cancer patients. ⋯ Fifty-eight articles including 19,084 individuals met full eligibility criteria. We observed that the frequency of BRCA1 gene promoter methylation was higher in breast cancer tissues compared with normal tissues, and the prognostic analysis suggested that BRCA1 gene promoter methylation was significantly associated with poor overall survival and poor disease-free survival. This study also verified that there was no statistically significant difference in the methylation frequency of BRCA1 gene promoter between peripheral blood and tumor tissues in breast cancer patients, which suggests that the detection of BRCA1 promoter methylation in peripheral blood may be a non-invasive and rapid way to monitor the occurrence breast cancer.

Meta Analysis
Prognostic role of the pretreatment C-reactive protein/albumin ratio in gastric cancer: A systematic review and meta-analysis.
In recent years, several studies have investigated the prognostic role of the pretreatment C-reactive protein/albumin ratio (CAR) in gastric cancer and yielded conflicting results. Therefore, we performed a meta-analysis to assess the prognostic role of the pretreatment CAR in gastric cancer. ⋯ A high pretreatment CAR was significantly associated with poor survival for patients with gastric cancer. The prognostic significance of the pretreatment CAR in gastric cancer is need to be confirmed by clinical trials of large sample size.
