Objective: To observe the effect of ATENS on distance and near vision and stereopsis in amblyopic children patients.Methods: 80 eyes from 70 patients with amblyopia were randomly divided into two groups: the group of ATENS and the group of western medicine.The difference of distance,near vision and stereopsis before and after treatment and between two groups after treatment were observed.Results: Distance and near vision improved and stereopsis diminished significantly after treatment in the TENS group and the western medicine group(P0.05).The curative effect and improving stereopsis in the western medicine group were better than that in the TENS group(P

OBJECTIVE: To analyze the factors influencing the therapeutic effect of "Shoulder Tri-needles therapy" in the treatment of shoulder-hand syndrome of stroke patients by using machine learning approach, so as to provide a feasibility for improving clinical efficacy. METHODS: A total of 586 stroke patients with shoulder-hand syndrome eligible for this study were involved in our machine learning experiments for classification of the influential factors. Their data including the age, gender, pulse condition, complexion, tongue quality, tongue coating, disease stage, body mass index (BMI), blood pressure, blood glucose, blood triglyceride, blood total cholesterol, smoking history, drinking history, and final outcomes were extracted from the medical record system (from Oct. of 2014 to Jan. of 2017 in the First Affiliated Hospital and Shenzhen Futian Hospital of Guangzhou University of Chinese Medicine). The single rule algorithm (1 R) was adopted to learn, followed by optimization with Repeated Incremental Pruning to Produce Error Reduction (RIPPER) algorithm, and C 5.0 decision tree algorithm. RESULTS: The accurate classification rates of 1 R, RIPPER and decision tree model were 87.37%(512/586), 95.90% (562/586), and 97.10% (569/586), respectively. The final outcomes of machine learning of this study showed that the disease stage (acute or recovery stage), complexion difference, tongue coating difference, blood pressure level, consumption of alcohol, BMI, and smoking habit were the most important factors influencing the therapeutic effect of "Shoulder Tri-needles" in the treatment of shoulder-hand syndrome of stroke patients. CONCLUSION: The disease stage, complexion and tongue identification, blood pressure level, alcohol drinking and smoking habits, and BMI are the principal factors affecting the therapeutic effect of "Shoulder Tri-needles therapy" in the treatment of shoulder-hand syndrome of stroke patients.

Objective:To investigate the expression of TIP30 and its relationship with clinico-pathological characteristics in patients with extrahepatic cholangiocarcinoma (ECC).Methods:The expression of TIP30 in 78 cases of ECC tissues and 78 cases of para-cancerous tissues were detected by immunohistochemistry.Results:The positive expression rate of TIP30 was 43.59％ and 75.64％ in ECC tissues and para-cancerous tissues,respectively.Differences were statistically significant (P＜ 0.05).The expression levels of TIP30 were not correlated with age,gender,degree of differentiation and tumor size(P＞0.05),but correlated with lymph node metastasis,distant metastasis and TNM staging(P＜ 0.05).The median overall survival of 78 ECC cases was 14.8 months,and it of TIP30 positive expression cases was 20.3 months,statistically higher than 11.5 months in TIP30 negative expression cases(P＜ 0.01).Conclusion:The downregulation of TIP30 is closely correlated with the development,metastasis and prognosis of ECC.TIP30 may be used as a molecular marker to identify and predict the progression,metastasis and prognosis of ECC.

Objective To study the inhibitory effect of antigliomatin on the expression of vascular endothelial growth factor(VEGF) in rat C6 brain glioma cells.Methods The rat brain glioma cells was cultivated with the stationary culture technique.The different rat C6 brain glioma cells groups were treated with 2,4,8,and 16 ng?L-1 antigliomatin for 72 h in vitro and then the inhibitory effect of antiglioma on the expression of VEGF was observed with immunohistochemical method.Results The cytoplasm and(or) nucleus of most VEGF positive cells were stained to yellow brown.VEGF expressed significantly in cytoplasm of the rat C6 glioma cells in control group.The density of the VEGF positive cells was decreased in glioma compared with control group after treated with antigliomatin for 72 h(P

Objective:To investigate the efficiency of carbon nanotube(CNT)-PAMAM mediated entrance of anti-survivin oligonucleotide into HepG2 cells,and its effects on the proliferation of HepG2 cells.Methods:CNT-PAMAM-anti-survivin oligonucleotide compounds were prepared and characterized by AFM and 1% agarose gel electrophoresis analysis.TEM was used to observe the distribution of CNT-PAMAM-ASODN compounds in HepG2 cells.CNT-PAMAM-ASODN compounds were added into the medium and co-cultured with HepG2 cells for 24 h,48 h,72 h,and 96 h at 37℃,5% CO_2.MTT method was used to detect the effects of ASODN and CNT-PAMAM-ASODN on the proliferation of HepG2 cells.Results:CNT-PAMAM-ASODN compounds were successfully synthesized via AFM and agarose gel electrophoresis.TEM showed that the compounds were located in the cytoplasm.When CNT-PAMAM-ASODN(1.0 ?mol/L)and ASODN(1.0 ?mol/L)were used for a 48 h culture,the inhibitory rates of HepG2 cells were(45.97?4.28)% for CNT-PAMAM-ASODN compounds group,(9.33?0.85)% for ASODN group,and(6.37?0.69)% for CNT-PAMAM group.CNT-PAMAM-ASODN compounds at 1.5 ?mol/L inhibited HepG2 cells by(70.22?7.25)%,and the inhibitory effects were in a time-and concentration-dependent manner.There was statistical difference between experiment group and control group(P

Objective To investigate the value of integrin αvβ3 targeted microSPECT/CT imaging with 99 Tcm-3P4-RGD2 as a radiotracer in tumor anti-angiogenesis therapy .Methods Animal models bearing glioma and prostate cancer xenografts were established by subcutaneously injecting tumor cells U87MG and PC-3 in nude mice.Anti-angiogensis therapy with Avastin was administered via intraperitoneal injection when the tumor diameter reached 6 to 7 mm while saline was served as control group . MicroSPECT/CT imaging was performed with 99 Tcm-3P4-RGD2 as radiotracer one day before and 3, 5, 10, 15 days after Avastin administration .Tumor volume and tumor uptake of 99 Tcm-3P4-RGD2 , expressed as percentage of injected dose (%ID) or %ID per gram (%ID/g) were measured and calculated based on microSPECT/CT.Mice basic condition was monitored and tumor xenograft was harvested in one tumor bearing nude mouse after its sacrifice at each imaging time point .Results Tumor volume of U87MG glioma in the administration group was significantly smaller than that of non-administration control group at 10 d after Avastin adminstration ( t=5.81, P<0.05), while no significance was observed between the administration group and its control group of PC-3 tumor (P >0.05).The uptake of 99Tcm-3P4-RGD2 (%ID/g) in U87MG group was higher than that in PC-3 group before Avastin administration ( t=10.48, P<0.05), and it decreased to a value less than control ( t =3.26, P <0.05) at 3 d after Avastin administration and continually reduced at longer time after administration .PC-3 tumor had less uptake of 99 Tcm-3P4-RGD2 in both Avastin administration group and its control group .The pathologic results revealed on that the decrease of tumor integrin β3 expression in U87MG treatment group was mainly on the endothelial cells of the neovessel .Linear relationship was verified between tumor uptake (%ID/g ) and integrin β3 expression (y=0.499 1x-0.243 8, R2 =0.811 7).Conclusions Complete inhibition of integrin is demonstrated early after Avastin administration .99 Tcm-3P4-RGD2 microSPECT/CT imaging, assessing the expression level of integrin αvβ3 level by quantification of tumor uptake of 99 Tcm-3P4-RGD2 , is probably an important method to reflect the early therapeutic effect of tumor anti -angiogensis .
