In the recent years,many studies have confirmed that vascular endothelial progenitor cells(EPC)can migrate,proliferate and differentiate into mature endothelial cells.They participate in the angiogenesis not only during the process of embryonic development but also during the growth and metachoresis of tumor.Therefore,further studies on EPC are important for the understanding of the formation and treatment of tumor.This review summarizes the research progress in this field.

Objective To study the radiosensitization effects of tetrandrine on advanced non small cell lung cancer and its toxicity.Methods The patients of 82 cases with advanced non-small cell lung cancer were confirmed by pathology or cytology.The first course of treatment was treated with radiation therapy.Patients were divided into three groups:tetrandrine group,paclitaxel group and radiotherapy group.Tetrandrine group(30 cases)took radiotherapy with 40 mg tetrandrine(3 times a day)from the first day to the ending.Paclitaxel group (29 cases)took radiotherapy with intravenous infusion of 60 mg paclitaxel(once a week).Radio-therapy group (23 cases)only received radiotherapy.Results Tetrandrine and paclitaxel had the same radiosensitizing effect in ra-diotherapy.The total effective rate of tetrandrine and paclitaxel group was higher than radiotherapy group (P <0.05 ).The inci-dence of radiation pneumonitis in tetrandrine group was significantly lower than the other two groups (P <0.05).The one year free disease survival rate was promoted in tetrandrine group than other groups.Conclusion Tetrandrine was known as the same radia-tion sensitizing effect of paclitaxel fairly,which can reduce the toxicity of radiotherapy.

OBJECTIVETo study the effect of Astragali Radix on the denervated tibial muscle atrophy in rats, and discuss its mechanism.

METHODTotally 60 SPF-grade Sprague-Dawley rats were selected in the common peroneal nerve crush model, and then randomly divided into 6 groups: Astragali Radix high-dose, medium-dose, low-dose groups, the Mecobalamin group, the model group, and the sham operation group. They were administered with drugs after the operation. At 18 d, the pathological section staining and morphological analysis were performed. The wet-weight ratio and section area of tibial muscles were also measured. The real-time fluorescence quantification was adopted to detect the differential expression between Angptl4 and PI3K genes.

RESULT(1) Wet-weight ratio: The wet-weight ratio in Astragali Radix high-dose, medium-dose groups was much higher than that in the model group (P < 0.05 or P < 0.01). (2) Section area: The sham operation group was higher, with regular morphology; Whereas the model group showed significant decrease, with chaotic structure and obvious connective tissue proliferation; Astragali Radix groups and the mecobalamin group showed relatively small section areas, with chaotic structure and unobvious connective tissue proliferation. Compared with the model group, Astragali Radix groups showed significant increase (P < 0.01). (3) Motor end plate: The sham operation group was in uniform brownish black color and oval or round shape; Astragali Radix medium-dose and high-dose group and the mecobalamin group showed rough line edges; Astragali Radix medium-dose and low-dose groups and the model group showed decline in the number, with irregular morphology, rough line edges and a light color. (4) Angptl4 and PI3K: Compared with the model group, the Astragali Radix high-dose group showed significant increase (P < 0.05).

CONCLUSIONAstragali Radix has a significant effect in preventing and treating denervated tibial muscle atrophy. It may delay the muscle atrophy by increasing Angptl4 and PI3K gene expressions.

Objective: To explore the diagnosis, therapy, and prognosis of multiple myeloma (MM) involved in central nervous system infiltration. Methods: The clinical data on the diagnosis, therapy, and prognosis of 9 MM patients with central nervous system infiltration were analyzed retrospectively. Results: Nine out of 418 MM patients had central nervous system infiltration. The occurrence frequency was 2.2%. Meningeal infiltration was the most common complication (5/9) and pituitary infiltration was the second (2/9). All the patients had several extramedullary diseases in other soft tissues. The median follow-up interval was 30 months. The median overall survival (OS) time of the 9 patients was 29 months. After the central nervous system was infiltrated, the median OS time was only 5 months. Conclusion: Central nervous system infiltration occurrs rarely in MM. Meningeal infiltration is the most common complication and frequently accompanied with other soft tissue plasmacytoma. The prognosis is unfavourable for those patients with central nervous system plasmocytoma. There is no effective interferring method in clinic.

Objective: To study the role of mRNA expression of inducible nitric oxide synthase (iNOS) in the occurrence and development of oral squamous cell carcinoma (OSCC) and the relationship between the expressions of iNOS mRNA and the clinical pathologic characteristics of OSCC. Methods: In situ hybridization assay was used to detect iNOS mRNA in 10 cases of normal oral mucosa, 12 cases of oral epithelial simple hyperplasia, 28 cases of oral epithelial atypicall hyperplasia, and 32 cases of OSCC. Results: The expressions of iNOS mRNA was negative in the normal oral mucosa. The expression of iNOS mRNA in both atypical hyperplasia and OSCC groups were significantly higher than that in simple hyperplasia group (P <0.001). Statistical analysis showed a significant correlation between iNOS mRNA expression and the grade of atypical hyperplasia (P <0.05). No significant difference of iNOS mRNA expression was found between atypical hyperplasia and OSCC groups (P > 0.05). The expression of iNOS mRNA in the group of well-, moderately- and poorly-differentiated squamous cell carcinoma was significantly different (P < 0.05). The expression of iNOS mRNA in stage III and IV OSCC tissues was significantly higher than those at stage I and II, and significantly higher in OSCC patients with neck lymph node metastasis than those without neck lymph node metastasis (P <0.05). Conclusion: iNOS mRNA may play an important role in OSCC development and progression. The expression of iNOS has a close relationship with the differentiation, TNM stage, and neck lymph node metastasis of OSCC. Detection of NOS may be useful in evaluation of patient's prognosis and guidance of OSCC treatment.

Objective: To study the clinicopathologic properties of hippocampus glioma with temporal lobe epilepsy(TLE) as the main manifestation. Methods: The clinical data of 6 patients with TLE and hippocampus masses were retrospectively analyzed. The 6 patients included 2 males and 4 females, with the longest history of epilepsy being 4 years. Results: All the 6 patients were surgically treated and were pathologically confirmed to have gliomas, including one angiocentric glioma( AG), one pilocytic astrocytoma (PA) with mucous degeneration, one astrocytoma, one oligoastrocytomao, one oligodendroglioma and one glioblastoma. Glial fibrillary acidic protein(GFAP) was strongly positive in all cases. Epilepsy disappeared after surgery in 5 cases; one patient had recurrence and received a second operation. Conclusion: Hippocampus gliomas with TLE as the main manifestation are usually low-grade gliomas of various types, and operation can obtain satisfactory prognosis.

ObjectiveTo explore the effective methods to improve the pulmonary function and life quality of patients with idiopathic pulmonary fibrosis (IPF).Methods48 IPF patients were randomly divided into two groups, each group includes 24 cases. Group A was treated with prednisone 0.5 mg/kg per day orally, reduce half of the dosage 4 weeks later and Fluimucil 600 mg three times per day orally, while group B with prednisone 0.5 mg/kg per day orally, reduce half of the dosage 4 weeks later. The clinical manifestation, pulmonary function testing, high-resolution CT of the chest, arterial blood gas analysis were observed before and 3 months after treatment. ResultsThere was significant difference in Group A (P<0.05) but no significant difference in Group B (P>0.05) before and after treatment in the pulmonary function testing and arterial blood gas analysis. There was significant difference after treatment in the pulmonary function testing and arterial blood gas analysis between Group A and Group B (P<0.05).There was significant difference after treatment in the clinical manifestation, high-resolution CT of the chest and between Group A and Group B (P<0.05). ConclusionHigh dose Fluimucil can ameliorate the pulmonary function, relieve the symptom of short breath of patients with idiopathic pulmonary fibrosis.

Objective To study the genome DNA methylation in rheumatoid arthirits(RA)and the re- lated factors of DNA methylation.Methods Twenty-first cases with RA and 20 controls were recruited to par- ticipate the study.Plasma Hcy,SAM,SAH,the MTHFR gene C677T polymorphism and the expression of LFA-1 in CD4~+T cells was measured in all patients and controls.Results①The SAM levels were lower sig- nificantly in RA groups than in controls.The SAH levels were higher significantly in RA groups than in con- trols.②There was significant inverse correlation between plasma Hcy level and SAM level(r=-0.932,P＜0.01). There was significant positive correlation between plasma Hcy level and SAH level(r=0.924,P＜0.01).③The expression of LFA-1 in CD4~+T cells was higher significantly in RA groups than in controls.There was a signif- icant positive correlation between LFA-1 expression level and Hcy level(r=0.557,P＜0.01),a significant in- verse correlation between LFA-1 expression level and SAM level(r=-0.651,P＜0.01).④The MTHFR gene mu- tation lead to dramatically increase of Hcy,SAH level and the expression of LFA-1 level in CD4~+T cells and genome DNA hypomethylation.Conclusion①Hypomethylation of genome DNA is found in most RA pa- tients.②The factors associated with genome DNA hypomethylation include MTHFR gene mutation and hyper- homocysteinemia.③The expression of LFA-1 in CD4~+ T cells is higer in RA groups than in controls,which re- lates to the DNA methylation level and the MTHFR gene C677T polymorphism.
