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.

AIM: To investigate the role of retinal pigment epithelium (RPE) in the growth of Müller cells using a co-culture system in vitro . METHODS: Müller cells were cocultured with RPE cells under both normoxic and hypoxic conditions in Transwell chamber culture system. Müller cell proliferation was evaluated by MTT assay. The number of cells which migrate through micropores and stay on the outer bottom side of insert systems were observed and counted. RESULTS: The activities of proliferation and migration of Müller cells when cocultured with RPE cells were significantly higher than those of the Müller cells when cultured alone at all time points under both normoxic and hypoxic conditions. However, for both the coculture and control groups, there is no significant difference between the measurements at 3 and 6 hours. CONCLUSION: Evidence suggests that RPE, when co-cultured with Müller cells, can stimulate migration and proliferation of Müller cells under both hypoxic and normoxic conditions in a time-dependent manner; how-ever, there is no evidence to support the synergetic interaction of RPE and Müller cells co-cultured under hypoxic conditions.

· Vascular endothelial growth factor is indispensable inducing factor in retinalangiogenesis. After the retinal neovascularization of proliferative diabetic retinopathy ( PDR ) patients, it can cause fibrovascular membrane formation, epiretinal membrane fibrosis increased, resulting in traction retinal detachment with further aggravate the condition. The recent research suggests that cytokines promote fibroblast proliferation, movement, adhesion, and secretion of extracellular matrix functions in the diabetic state of the environment changes to profibrogenic state, resulting in the accumulation and fibrosis of extracellular matrix. This paper reviewed the status quo of the correlation between vascular endothelial growth factor and fibrosis-related cytokine.

0.05). Regarding to the grade of irradiation mucositis, the majority of patients in the treatment group were at stage Ⅰ-Ⅱ,while those in the control at stage Ⅲ-Ⅳ(P0.05).No adverse drug reaction was observed in both groups during irradiation process.Conclusion:Actovegin can postpone the development of irradiation oropharyngeal mucositis and decrease the incidence of gradeⅢ and Ⅳmucositis.

Objective To establish a method of reverse hybridization to detect five subfamilies of low risk Human Papillomaviruses(HPV6,11,42,43 and 44)and eighteen subfamilies of high risk HPV (HPV16,18,31,33,35,39,45,51,52,53,56,58,59,66,68,73,83 and MM4)in one reaction.Methods Special probes for twenty-three HPV subfamilies were fixed on nylon membrane bars,biotin labeled general primers mediated polymerase chain reaction(GP-PCR)were applied in HPV DNA amplification.PCR amplified DNA fragments were reversely hybridized with special probes that were fixed on the membranes. All samples(136)detected by reverse hybridization method were paralleled with the methods of Hybridization Capture Ⅱ(HC-Ⅱ)and sequencing.Results Positive rate of the 136 samples detected by reverse hybridization was 41.9%,while HC-Ⅱ 42.6% and sequencing 40.4%.Reverse hybridization detection indicated coherence with the other two methods(Kappa 0.8644 and 0.9089,respectively).While sequencing was lab standard for DNA test,the sensitivity was 96.36%,specificity was 95.06%,accuracy was 95.59%.Conclusions Method of reverse hybridization is adaptable to 23 kinds of HPV subfamilies, which can confirm the exactly subfamilies of HPV infection.This method is adaptable in clinical detection of HPV,with high sensitivity,high specificity,simply and convenient operation and the results are easily to be read.

Objective To investigate the clinical value of bone scintigraphy for the diagnosis of synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome. Methods The characteristics of SAPHO syndrome on 99Tcm-MDP imaging of 8 cases were retrospectively analyzed. Results The 99TcmMDP bone scan was positive for all patients. Seven cases were found lesions in the costoclavicular region, 3cases involved with unilateral sacroiliac joint, 2 cases involved with spine and 1 patient with extremity. Four lesions were found without relevant clinical symptoms. Conclusion Bone scintigraphy is useful for the diagnosis of SAPHO syndrome, especially for those lesions with no clinical symptoms.
