Objective:
To explore the inhibitory effect and possible mechanism of Baicalin on the human tongue squamous cell carcinoma cell line SCC15 and to provide a new idea and experimental basis for the clinical prevention and treatment of tongue squamous cell carcinoma.
Methods :
SCC15 cells cultured in DMEM alone were used as the control group, and SCC15 cells cultured in 20 mg/mL baicalin solution were used as the baicalin group. Scratch tests and Transwell migration tests were performed to detect changes in cell migration ability, and flow cytometry was used to detect changes in the cell cycle. Western blotting was used to detect differences in the phosphorylation levels of signal transduction and transcription activator 3 (STAT3).
Results :
Compared with the control group, the scratch test and the Transwell migration test showed that the cell migration ability of cells in the baicalin group was significantly decreased (t=4.927, P=0.008); flow cytometry showed that the number of cells of the baicalin group increased in the G0/G1 phase (t=9.893, P=0.001), decreased in the S phase (t=8.528, P=0.001), and decreased in the G2/M phase (t=3.550, P=0.024); Western blotting results showed that the STAT3 protein of SCC15 cells in the baicalin group decreased (t=3.550, P=0.024), and the phosphorylation level significantly decreased (t=8.262, P=0.001).
Conclusion
Baicalin inhibits the human tongue squamous cell carcinoma cell line SCC15, and its mechanism may be related to a decrease in STAT3 pathway phosphorylation activity.

Objective To investigate the functions of FABP5 in the carcinogenesis and development of cervical cancer. Methods The expression of FABP5 was detected in several cervical cancer cell lines (C33A, Siha, Caski, HeLa and HCC94), 206 cases of cervical cancer tissues with stageⅠa2?Ⅱa2 and 40 cases of normal cervical tissues by real?time PCR and Western blotting. Then, the cells were infected with lentivirus?mediated siRNA?targeting FABP5. CCK?8 cell proliferation, colony formation, wound healing and transwell assays were used to investigate the effects of FABP5 on in vitro cell proliferation, migration and invasion. And in vivo xenograft model and lung metastasis model were used to observe the transplanted tumor growth and metastasis in female athymic nude mice. Furthermore, the total protein and RNA were extracted from the primary xenografts to determine the expression levels of FABP5, metalloproteinase?2 and metalloproteinase?9 using Enzyme linked immunosorbent assay ( ELISA ), real?time PCR and Western blotting.Results FABP5 expression was found to be significantly unregulated in cervical cancer tissues than that in normal cervical tissues ( P<0.05). Compared with the Siha?NC group and uninfected group, the expression of FABP5 mRNA and protein in Siha?FABP5?RNAi group was significantly inhibited along with the decrease of cell proliferation, colony formation, wound healing and invasion ability. The clone formation rates of Siha cells in uninfected group, Siha?NC group and Siha?FABP5?RNAi group were (84.6± 4.5)%, (84.6±5.1)% and (21.2±2.6)%, respectively. Moreover, the transwell assay showed that invasive cells in three groups were (72.8±4.7)/HPF, (72.6± 3.3)/HPF and ( 21.4± 2.3)/HPF, respectively. All of the difference was statistically significant (P<0.05). Furthermore, FABP5 silencing significantly reduced tumor growth and lung metastases in nude mice in vivo ( P<0.001). The subcutaneously xenografted volume in uninfected group, Siha?NC group and Siha?FABP5?RNAi group was (921.4±63.0) mm3, (1 021.4±56.0) mm3 and (139.6±36.0) mm3, respectively. The real?time quantitative PCR results showed that the relative expression levels of MMP?2 and MMP?9 mRNA were 1.00±0.10 and 1.00±0.10, 1.00±0.10 and 1.00±0.10 as well as 0.34±0.13 and 0.38±0.17 in xenografted tumor tissues of uninfected group, Siha?NC group and Siha?FABP5?RNAi group, respectively. MMP?2 and MMP?9 was significantly downregulated after FABP5 inhibition(P<0.05). Additionally, the protein expression trend of MMP?2 and MMP?9 in three groups was consistent with the mRNA levels. Conclusion FABP5 might promote the carcinogenesis and metastasis of cervical cancer via up?regulating MMP?2 and MMP?9.

Objective:
To evaluate the application of the expanded free deltopectoral flap, pedicled with perforation of internal thoracic artery, in the repairment of middle to large facial skin and soft tissue defect.
Methods:
From June 2015 to December 2017, 11cases diagnosed with facial lesions were included in this study. The tissue defect of 10 cases were caused by burn, and 1 case by superficial tumor. In the first stage, the tissue expander was implanted into the internal thoracic artery supplying area. After the expander was fully expanded, the second surgery, i. e. the resection of facial lesion, was performed. The defect areas of patients, with the range of 9 cm×7 cm to 17 cm×10 cm, were repaired by expanded free deltopectoral flaps.
Results:
All flaps were survived, with no vascular crisis occurred. The size of flaps ranged from 10.0 cm×9.0 cm to 18.0 cm×11.5 cm. All the patients were satisfied with the outcomes, after 6 to 24 months follow-up. The color and texture of flaps was close to normal. The scars were acceptable.
Conclusions
The expanded free deltopectoral flap, pedicled with the perforator of internal thoracic artery, is a promising way to repair middle to large facial skin and soft tissue defect.

miRNAs are a class of small endogenous RNAs that degrade target mRNAs or repress their translation process. Several miRNAs in glioma are up?regulated, while some others down?regulated. Some miRNAs promote tumorigenesis; some others, however, play a similar function of tumor suppressor genes. Therefore, studies on the expression profiles of miRNAs in glioma may afford auxiliary basis for early clinical diagnosis and novel srtategies for therapy of glioma. This paper will review on researches about the expression levels of miRNAs and their targets in glioma.

Objective To study the cell immunity and eytokines responses to avian influenza A H5N1 virus infections in a BALB/c model to better understand the pathogenesis of H5N1 avian influenza disease. Methods Two hundred and twenty BALB/c mice of the infected group were inoculated with 0.1 ml (10-4.875 TCID50) of A/Goose/Guangdong/NH/2003 ( H5N1 ) virus intra-nasally. Fifty control mice received noninfectious allantoic fluid and another fifty control mice received normal sodium. Blood and spleen samples were collected from the live mice every 24 h during the 14 d post-infection. The changes of CD3 + T cells , CD4 + T cells, CD8 + T cells for cell immunity in blood circulation and spleen were detected by flow cytometry. And the cytokines and antibody responses in blood circulation were detected by ELISA. Necropsy was performed on mice that died during the experiment and those euthanized at end of study. Results Avian influenza A( H5N1) virus infections can make damages to the cell immune system transiently. The CD3 + T cells, CD4 + T cells, CDS + T cells declined at 24 days post infection in blood circulation and declined at 5-8 days in spleen, then recovered to the normal level gradually. The eytokines responses to the infections can be detected: the level of IFN-γ,TNF-α declined, IL-4, IL-18, IL-10 increased, and IL-2 changed little. The antibody increased rapidly from day 7 post infection until the end of the study (day 14 post infection). Conclusion Collectively, avian influenza A(H5N1) virus can cause cell immunity deficiency and an imbalance in the level of eytokines, which may contribute to the unusual severity of disease caused by the H5N1 avian influenza virus.
