AIM: By introducing the thinking and experience of professor Deng Tietao to treat myasthenia gravis, to improve the therapeutic effect and prognosis.benefiting vital qi had been the main line throughout the whole process of phasized that while we grasp spleen-asthenia, we must give consideration to other organs at the same time, regulate and treat the patient with multistrengthening muscle and increasing strength (radix astragali, radix codonopsis pilosulae, rhizoma atractylodis macrocephalae, rhizoma cimicifugae, pericarpium citri reticulatae, radix fici simplicissimae, etc.), the disease had been treated with different dosage of drugs according to the py for one or two years, even though the symptoms had disappeared completely.RESULTS: Because of grasping the root cause, therapy with multi-means and modified prescription according to the varied symptoms, it had a satisfactory effect. An excellent therapeutic effect had been obtained with the decoction for strengthening muscle and increasing strength, which is created by Deng himself.CONCLUSION: Deng's theory holds that myasthenia gravis is mainly due to spleen-asthenia, and related to other four organs (with a predominance of kidney), and the therapy should be strengthening the spleen-qi, so the prescription was selected for strengthening muscle and increasing strength (which is created by Deng himself), with radix astragali being in a lager quantity. Moreover, he paid more attention to psychological therapy and dietary regulation. The Deng's theory is of considerable clinical significance in guiding treatment of myasthenia gravis.

Hilar cholangiocarcinoma always presents with a mass, thickness of the bile duct wall or nodules in the bile duct. Computed tomography (CT) can demonstrate the above findings with high partial resolution as well as dilation of the intrahepatic bile duct. CT can show the field and the involvement of adjacent vessels on 3D reconstruction images for hilar cholangiocarcinoma spreading along the lumen of the bile duct. CT images can also demonstrate vessel involvement when evaluating the resectability. When combined with 3D reconstruc-tion, the sensitivity and specificity of CT imaging can reach 90.5% and 91.7% , respectively, for detecting vessel involve-ment.

Background Many studies showed that attenuation of retinal nerve fiber layer(RNFL)in early glaucoma is one of the important signs.How to accurately and quantitatively measure RNFL thickness is very important for the early diagnosis and monitoring of glaucoma.0bjective This study was to evaluate the clinical value of Optovue RTVue OCT and Heidelberg Retina Tomograph Ⅲ(HRT-Ⅲ)confocal scanning laser ophthalmoscopy in glaucomatous eyes. Methods This cross-sectional study included 40 eyes of 26 patients with suspected open-angle glaucoma(SOAG),48 eyes of 29 patients with open-angle glaucoma and 48 eyes of 27 healthy subjects.Optical nerve head(ONH) parameters and peripapillary RNFL thickness were measured in all the subjects with Optovue RTVue OCT and HRT-Ⅲ,meanwhile all the eyes received perimetry with Humphrey 750-I.Glaucoma variables obtained from Optovue RTVue OCT and HRT-Ⅲ were analyzed among the groups.Topographic Optovue RTVue OCT and HRT-Ⅲ parameters,including disc area(DA),cup area(CA),rim area(RA),rim volume(RV),cup volume(CV),cup/disc area ratio(C/DAR)as well as superior,temporal,inferior and nasal average RNFL thickness,were analyzed.The relationship of ONH parameters and RNFL thickness was analyzed using a linear correlation.The correlation between the mean defect(MD)of the visual field and the tomography parameters in glaucomatous eyes was described by bivariate Pearson correlation coefficients.Resuits The ONH parameters and RNFL thickness obtained by HRT-Ⅲ and OCT showed significant difference(P<0.05).ONH parameters such as RA,C/DAR,CA and RV were statistically changed in SOAG and the POAG patients compared with the normal subjects(q=6.47,q=7.67,P<0.05).The superior and inferior RNFL thickness parameters in three groups were positively correlated between HRT-Ⅲand OCT(r=0.362,r=0.441,r=0.395,P<0.05),Topographic Optovue RTVue OCT and HRT-Ⅲ parameters including CV,CA,RA and C/DAR fitted Pearson analysis(all P<0.05).In POAG group。The RA,RV,CV,C/DAR from Optovue RTVue OCT were correlated with MD with the significant coefficient 0.284,0.286,0.340,0.371 respectively(P<0.05),and evidently correlations also were found between RA,RV,C/DAR with MD respectively with the coefficient 0.339,0.859,0.422(P<0.05)by HRT-Ⅲ. Conclusion Both Optovue RTVue OCT and HRT-Ⅲ can difierentiate ONH analysis with a similar outcome in glaucomatous eye.The C/D value.RA,superior and inferior RNFL thickness based on Optovue RTVue OCT and HRT-Ⅲare distinguishing indexes in the diagnosis of early glaucomatous damage.

The electrochemical behaviors of parathion(PT) on nano-Al2O3 film modified electrode(nano-Al2O3/GCE/CME) were investigated. It was found that the redox peak currents of PT remarkably increased and the oxidation peak potential negatively shifted at the nano-Al2O3/GCE/CME. All the experimental parameters were optimized and a simple and sensitive electroanalytical method was developed for the determination of PT. The oxidation peak current was linear with the concentration of PT over the range from 2.5×10-9 to 1.0×10-7 mol/L and 1.0×10-7 to 1.0×10-5 mol/L. A low detection limit of 1.0×10-9 mol/L was obtained for 30 s accumulation at open circuit(S/N=3). The relative standard deviation(n=10) was 3.8% for 1×10-5 mol/L PT. The proposed method was used for the quantitative analysis of PT in some vegetables and the results were satisfactory.
