RESUMO
The emergence of single-cell sequencing technology enables people to observe cells with unprecedented precision. However, it is difficult to capture the information on all cells and genes in one single-cell RNA sequencing (scRNA-seq) experiment. Single-cell data of a single modality cannot explain cell state and system changes in detail. The integrative analysis of single-cell data aims to address these two types of problems. Integrating multiple scRNA-seq data can collect complete cell types and provide a powerful boost for the construction of cell atlases. Integrating single-cell multimodal data can be used to study the causal relationship and gene regulation mechanism across modalities. The development and application of data integration methods helps fully explore the richness and relevance of single-cell data and discover meaningful biological changes. Based on this, this article reviews the basic principles, methods and applications of multiple scRNA-seq data integration and single-cell multimodal data integration. Moreover, the advantages and disadvantages of existing methods are discussed. Finally, the future development is prospected.

Objective To explore the clinical effect of Tongluo-Ningxue decoction for hematuria from IgA nephropathy. Methods A total of 60 patients with IgA nephropathy in the hospital between July 2015 and August 2016 were randomly divided into two groups, with 30 cases in each group. The control group was treated with western medicine (Benazepril Hydrochloride plus dipyridamole), whereas the observation group took Tongluo-Ningxue decoction for treatment. The clinical efficacy, clinical symptom score, biochemical index and humoral immune index in the two groups were compared. Results The effective rate was 86.7％ (26/30) in the observation group, and 63.3％ (19/30) in the control group, with the difference between the two groups being statistically significant (χ2=4.356, P=0.037). After treatment, the scores of fatigue and weakness (0.7 ± 0.1 vs. 1.4 ± 0.2, t=18.954), soreness and weakness of waist and knees (0.7 ± 0.1 vs. 1.4 ± 0.2, t=21.071), swollen sore throat (0.6 ± 0.1 vs. 1.4 ± 0.2, t=20.723), and hot flashes and night-time sweating (0.6 ± 01 vs. 1.5 ± 0.2, t=20.732) in the observation group were significantly lower than those in the control group (P<0.05). After treatment, the 24h UP (0.53 ± 0.12 g vs. 0.74 ± 0.15 g, t=5.988), RBC (16.84 ± 5.38 vs. 21.42 ± 9.73, t=2.256), SCr (56.34 ± 7.21 μmol/L vs. 61.27 ± 8.45 μmol/L, t=2.431), and IgA (2.35 ± 0.43 g/L vs. 2.62 ± 0.45 g/L, t=2.376) in the observation group were significantly lower than those in the control group (P<0.05). Conclusions The Tongluo-Ningxue decoction can improve the biochemical indicators, enhance immunity, improve renalfunction and relieve clinical symptoms, and therefore, it is worthwhile for the clinical application.
