"Wise men could recognize similarities, but the fool only recognizes differences" in Su-wen, which expounded clinical thinking methods of Chinese medicine (CM). "To recognize similarities and differences simultaneously" is of important clinical significance in understanding the laws of diseases. CM pays much attention to recognize similarities, while modern medicine emphasizes the differences observed. In order to develop integrative medicine (IM), similarities recognition and differences identification must be combined together to innovate new thinking methods of IM.

MicroRNAs (miRNAs) are small, single-stranded and noncoding RNA molecules of about 22 nucleotides (nt) in length that regulate mRNA by binding to 3' untranslated regions (3'UTR) of target mRNA, inducing digestion, degradation and/or translational repression of the latter. Posttranscriptional regulation of gene expression by miRNA is critical for a wide range of physiologic and pathologic processes, including cell proliferation, differentiation, apoptosis, development and oncogenesis. Dendritic cells (DC) are professional antigen presenting cells that have a pivotal role in controlling immune responses. The latest studies indicated that miRNA are indispensable in regulation of development, differentiation and functions of DC. This review discusses the latest studies of miRNA controlling DC biological properties in order to deep understand the regulatory mechanism of DC, therefore, provide a new thinking for the therapeutic strategies of DC-associated immunological disorders.

OBJECTIVETo screen microRNAs with specific expression of in hippocampus of rats with chronic stress induced depression model, and observe the effect of traditional Chinese medicine Chaihu Shugan San on the expression of microRNA in hippocampus.

METHODSD rats were randomly divided into 3 groups: the normal control group, the model control group and the Chaihu Shugan San group. The depression model was replicated by unpredictable chronic mild stress combined with separation. Behavioral changes of the rats were observed by Open-field test and sucrose solution consumption test, and the expression of microRNAs in hippocampus was assayed by microRNA micro-array.

RESULTCompared with the normal control group, there were 13 specific miRNAs in hippocampus in the model control group with the expression difference of more than 2 times. Among them, down-regulating miRNAs included miR298, miR-130b, miR-135a, miR-323, miR-503, miR-15b, miR-532, and miR-125a, and the up-regulation miRNAs included miR7a, miR-212, miR-124, miR-139, and miR-182. Among the 13 specific miRNAs, miR-125a and miR-182 recovered to normal after intervention with Chaihu Shugan San in the Chaihu Shugan San group.

CONCLUSIONThis study preliminarily found that 13 specific miRNAs in hippocampus are related to depression. Among them, miR-125a and miR-182 recover to normal after intervention with Chaihu Shugan San, which may be the target points of the antidepressant effect of Chaihu Shugan San. We shall further analyze the target genes and their mechanisms.

OBJECTIVETo evaluate the short-term outcomes of patients receiving orthopedic surgery with posterior pedicle screw fixation for degenerative lumbar scoliosis.

METHODSBetween March, 2006 and August, 2009, 36 patients with degenerative lumbar scoliosis (19 males and 17 females) underwent procedures of decompression, bone implantation and pedicle screw fixation. Fifteen patients were also treated by PLIF and 21 cases received posterior-lateral fusion. The JOA scores, Oswestry disability index (ODI), and Cobb angle were recorded before and after the operation, and the surgical complications were also observed.

RESULTSThe JOA scores increased significantly by 83.3% after the operation (P<0.05). The procedures resulted in significantly lowered ODI from (67.1∓11.4)% before the operation to (32.1∓10.8)% after the operation (P<0.01). A significant improvement of the coronal Cobb's angle was achieved after the operation (26.7° preoperatively vs 12.3° postoperatively, P<0.01), and the lordosis angle was improved from 10.7° to 36.6° after the operation (P<0.01). All the patients were followed up for 12 to 50 months (mean 38 months), and no implant loosening, displacement or fragmentation, or pseudarthrosis was found at the final follow-up.

CONCLUSIONPosterior pedicle screw fixation shows good short-term therapeutic effect in treatment of degenerative lumbar scoliosis. Individualized surgical plans and adequate preoperative evaluation are keys to successful operations.

OBJECTIVETo explore the effects of ICAM-1 gene transfection on the differentiation of MSCs to adipocytes.

METHODSThe recombinant retroviral expression plasmid MIGR1-ICAM-1 containing full length of mouse ICAM-1 gene was constructed. The constructed plasmid MIGR1-ICAM-1, empty plasmid MIGR1 and packaging plasmid ECOS were transfected into T293 cell lines and then the supernatant generated from T293 cells were used to infect mouse MSCs cell line C3H10T 1/2. The transfective efficiency was determined by inverted fluorescence microscope, real-time PCR and flow cytometry. Furthermore, ICAM-1 overexpressing MSCs (C3H10T 1/2-ICAM-1) and empty vector transfection MSCs (C3H10T 1/2-MIGR1) were cultured in medium with or without induction reagents, Oil-red-O staining was used to detect the lipid accumulation, and the expression of transcriptional factors C/EBPα and PPARγ, which were key factors in the differentiation of MSCs to adipocytes, were tested by real-time-PCR.

RESULTSThe recombinant retrovirus vector containing mouse ICAM-1 gene was successful constructed. After transfection into MSCs cell line C3H10T 1/2, the overexpression ICAM-1 MSCs cell line (C3H10T 1/2-ICAM-1) and control cell line (C3H10T 1/2-MIGR1) were obtained. Furthermore, these two cell lines were treated without or with adipocytic induction reagents, C3H10T 1/2-ICAM-1 showed significantly lower mRNA expression level for C/EBPα [(1.2 ± 0.7), (2.9 ± 0.9)] and PPARγ [(1557.6 ± 70.2), (7547.0 ± 442.2)] when compared with C3H10T 1/2-MIGR1 [(5.8 ± 0.5), (23.0 ± 2.3) and (2453.0 ± 215.6), (9856.3 ± 542.2)](P < 0.05). Moreover, little lipid droplet and decreased quantity of adipocytes were detected in C3H10T 1/2-ICAM-1 [(3.2 ± 0.5)/well, (12.2 ± 3.8)/well] than that in C3H10T 1/2-MIGR1 [(11.2 ± 0.4)/well, (51.3 ± 2.8)/well] (P < 0.05).
