3.Oxaliplatin and teniposide inhibited proliferation and induced apoptosis of gastric cancer cell line BGC-823
Tumor 2010;(1):31-35
Objective:To investigate the effects of oxaliplatin (OXA) and teniposide (VM-26) on proliferation and apoptosis of gastric cancer cell line BGC-823.Methods:MTT assay was used to examine the inhibition rate of cell growth when cells were treated at various concentrations of OXA and VM-26 alone or in combination. The apoptosis was examined by flow cytometry (FCM). The protein expression of cell apoptosis associated proteins caspase-9 and livin were examined by immunocytochemistry. Results:OXA or VM-26 effectively inhibited the growth of BGC-823 gastric cancer cells in a concentration-dependent manner at certain range of concentrations. The inhibitory rate of combined treatment with OXA and VM-26 was significantly higher than that of OXA or VM-26 alone (P<0.05). The value of combination index (CI) was 0.46. The rate of apoptosis cells induced by 1.25 μg/mL OXA was 6.13%, 13.86% and 21.48% at 12, 24 and 48 h. The apoptosis rate induced by 0.625 μg/mL VM-26 was 4.60%, 10.72% and 17.07% for 12, 24 and 48 h. In combined treatment group the apoptosis rate was 11.73%, 24.14% and 44.75% at 12, 24 and 48 h, respectively. The difference was significant between combined treatment group and single drug treatment group (P<0.05). Immunnocytochemical analysis showed that the expression of caspase-9 protein was up-regulated after being exposed to OXA (1.250 μg/mL) or OXA plus VM-26 (0.750 μg/mL), while the expression rate of livin protein was down-regulated. There were significant differences among different treatment groups as well as between treatment groups and control group (P<0.05).Conclusion:OXA combined with VM-26 has synergistic effects in inhibiting the growth and inducing apoptosis of gastric cancer BGC-823 cells.
4.Advance in research on CML therapy by gene silence and adoptive cellular immunotherapy
Military Medical Sciences 2013;(11):870-872
Chronic myeloid leukemia is a kind of malignant cloning hyperplastic disease of hematopoietic stem cell .The treatments based on molecular biological and immunological techniques will become the new therapies .Gene silence can improve the effects of molecular targeted therapeutic drugs through two ways: one is the target mRNA can be digested by siRNA and the other is target gene lose the stability and reduce the generation of protein mediated by miRNA .Adoptive cel-lular immunotherapy is a treatment method through injecting immunocompetent cells such as CIK , NK, etc into the body of cancerous person .This can improve the immunity of body and the effects of molecular targeted therapeutic drugs .The fur-ther study about basic theory , molecular mechanism and clinical effects will be continued .
5.Proto-oncogene Bmi-1 and head and neck cancer
Journal of International Oncology 2013;40(9):665-668
Bmi-1 is a core member of the polycomb group genes.As a proto-oncogene,Bmi-1 plays an important role in cell self-renewal,proliferation and apoptosis.Several studies have shown that Bmi-1 is highly expressed in some head and neck malignant tumors,such as nasopharyngeal cancer and laryngeal carcinoma.Furthermore,the expression level of Bmi-1 is closely related to the occurrence,development,incursion and prognosis of tumor.Bmi-1 is expected to become a novel tumor molecular marker,and provides a new direction for the treatment of the head and neck malignant tumor.
6.Analysis of differential urinary proteome in experimental minimal change nephropathy
Basic & Clinical Medicine 2010;30(3):232-236
Objective To screen early urine protein markers for minimal change nephropathy.Methods Adriamycin nephropathy was employed as minimal change nephropathy model.Urinary protein and ConA captured glycoproteins were respectively profiled.Results By profiling urine proteome,25 differential proteins were identified.These differential proteins were from leaked plasma proteins,secreted proteins from immuno-and inflammatory cells,specifically asecreted proteins from urinary tract,and so on.They took part in different pathogenic process,eg.hemodynamic changes,podocytes injury,immunological disorder and so on.By profiling ConA-enriched urinary glycoproteome,21 differential proteins were identified,among which 12(57%) were different from the above 25 differential proteins.This indicates that the knowledge of urine glycoproteome is complementary to urine proteome in understanding kidney condition.Conclusion These differential proteins can be potential indicators of minimal change nephropathy,and can help better understand the pathogenesis by further studying their functions.
7.Study on the expression of maspin gene and its role in patients with colorectal cancer
Chinese Journal of Microbiology and Immunology 2013;(5):351-354
Objective To investigate the relationship between the expressions of maspin gene in colorectal membrane,and their roles in the occurrence,progression,metastasis and prognosis of colorectal adenocarcinoma.Methods Immunohistochemistry technique was used to detect the expression of maspin in tissues of normal controls,adenoma,colorectal adenocarcinoma primary tumor,liver metastasis,lymph-node metastasis respectively.Results The expressions of maspin in normal controls,adenoma and colorectal adenocarcinoma primary tumor are down-regulated successively; the expression of maspin in colorectal adenocarcinoma with metastasis is lower than that in colorectal adenocarcinoma without metastasis(P<0.05) ; the down-regulation of maspin expression is significantly correlated with the depth of invasion,differentiation,liver metastasis and lymph node metastasis of colorectal adenocarcinoma(P<0.01,P<0.05,P<0.01,P<0.05).Conclusion The down-regulation of expression of maspin probably plays an important role in the occurrence,progression and metastasis of colorectal adenocarcinoma.maspin is probable a predictive index for reflecting the metastasis of colorectal adenocarcinoma and provide a clue for early diagnosis of metastasis of colorectal adenocarcinoma.

9.Effect of neuropeptides on periodontium and oral bone repair
Chinese Journal of Tissue Engineering Research 2014;(11):1780-1786
BACKGROUND:With the development of researches on periodontal disease etiology and neuroendocrine factors, the role of neuroendocrine factors on the pathogenesis of periodontal disease and tissue restoration has become a hot spot.
OBJECTIVE:To summarize the biological effect of neuropeptides on periodontal tissues and the changes of periodontal tissue after nerve injury.
METHODS:A computer-based search of articles was performed in CNKI, Wanfang and PubMed databases using the key words ofneuropeptides, calcitonin gene related peptide, substance P, vasoactive intestinal peptide, neuropeptide Y and periodontal tissuein Chinese and English. The included articles focused on the effect of various neuropeptides on periodontal tissue.
RESULTS AND CONCLUSION:Calcitonin gene related peptide, substance P, vasoactive intestinal peptide, and neuropeptide Y positive nerve fibers are widely distributed in periodontal support tissues. When sensory nerves are damaged, the target cel s in periodontal tissues are influenced due to changes of nerve fibers distribution and neuropeptide release. They also play a role in the reconstruction of alveolar bone, immune function of periodontal ligament and periodontal tissue. This evidence shows that neuroendocrine factors are closely linked with periodontal tissue. However, these studies concentrated in the animal models for orthodontic and fracture, the effect of the neurotransmitters such as neuropeptides on periodontal disease and the mechanisms need further exploration.

Chinese Journal of Biochemical Pharmaceutics 2014;(2):104-105
Objective To evaluate the clinical efifcacy of Matrine injection on malignant cancer pain treatment. Methods 100 patients in Central Hospital of Huanggang from February 2010 to April 2013 were randomly divided into two groups(control group and research group) for retrospective study(n=50). Based on the conventional treatment, control group were received three-step analgesic ladder, and research group were treated with matrine injections. The pain scores and Karn of sky scores were evaluated and compared before and after treatment in each group, and were compared between two groups. Results The pain score and Karn of sky score in research group after treatment were signiifcantly better than control group(P<0.05). Conclusion Matrine injection could relief pain level and improve patients' quality of life of malignant cancer patient.
