Objective To evaluate the distribution of non-motor symptoms(NMS) and dominant factors impacting on the prevalence of NMS in Parkinson's disease(PD). Methods The NMS questionnaire(NMSQuest) was administered to 128 patients(PD group) and 128 healthy adults(control group).The distribution of items of NMS was analyzed between the two groups,and clinical characteristics were also collected to assess the dominant factors impacting on the prevalence of NMS. Results There were significant differences in the prevalence of NMS between the two groups(P

In order to investigate the efficiency of a new quantitative head-band formed ocular compressor to reduce intraocular pressure (IOP), ocular compression by this new reducer with 40 mmHg for 10 min was performed on 87 cataractous eyes of 78 cases. The changes of IOP (87 eyes) and anterior chamber depth (ACD) were observed. There was a significant decrease of IOP and increase of ACD within 30 min after decompression (P < 0.001). The mean decrease of IOP was 5.62 +/- 2.41 mmHg and the mean increase of ACD was 0.18 +/- 0.09 mm within 5 min after decompression. The IOP 5 min after decompression had no significant difference with that 10 min after decompression (P > 0.05). IOP below 10 mmHg could last for about 15 min. This apparatus had been successfully applied to 80 eyes for extracapsular cataract extraction. It was suggested that this device had the advantages of safety, accurate quantification, reliable effect, casually adjusting pressure according to various demands and time-saving.

AIM:To establish the murine model of oxygen induced retinopathy ( OIR) and to evaluate the inhibition of retinal neovascularization by erythropoietin ( EPO) blockade.
METHODS: Neonates of C57BL/6 mouse ( P7 ) were exposed to 75%±2% oxygen for 5d and return to normal air environment when 12d ( P12 ) to establish oxygen-induced retinal neovascularization model. The neonates were divided into groups, injected with 0. 5μL solution containing 25ng ( group A), 50ng ( group B), 250ng ( group C) of soluble erythropoietin receptor ( EPO-R) or PBS (group D) at P12, P14 and P16 in the right eye. On P17, the litters were sacrificed and their right eyes were enucleated and fixed with 4% paraformaldehyde, made pathological section. The number of breakthrough internal limiting membrane neovascular nuclei was counted with pathological retinal morphology, understanding theproliferative degree of retinal neovascularization.
RESULTS: The pathological sections showed the neovascular cell nuclei which penetrating the inner limiting membrane in intravitreal EPO receptor injection group was reduced statistically than that in PBS injection group, the difference was statistically significant ( P<0.01). And, neovascular nuclei count differences in the
various concentrations of EPO receptor group was statistically significant (P<0. 01). With the EPO receptor concentration increase, neovascular endothelial cells broken through the internal limiting membrane was reduced.
CONCLUSION: Intravitreal injection of soluble EPO receptor can block EPO and improve neovascularization. The new method is expected to become new treatment of ocular neovascular diseases.
5. Analysis and evaluation on main active ingredients of Asarum heterotropoides var. mandshuricum from different habitats
Chinese Traditional and Herbal Drugs 2020;51(3):748-756
Objective: Active ingredients of 47 Asarum samples from different habitats with different phenotypes were analyzed in this paper in order to reveal the relationship between the formation of active ingredients and genetics and geography, and provide some scientific basis for the breeding and untilizing of Asarum. Methods: Ethanol extract and volatile oil were extracted according to the methods of Chinese Pharmacopoeia. Asarinin was detected by HPLC. Volatile oil compositon was determined by GC-MS. The between-groups linkage clustering method was carried out. Results: Volatile oil content of 47 samples was 0.81%-3.32%, and five samples’ volatile oil content exceeded 3.0 %. Ethanol extract content of samples was 9.87%-29.40%, and ethanol extract content of 30 resources accounting for 63.8 percent of all samples exceeded 20%. Asarinin content of 26 resources was more than 0.25%. Totally 48-77 compounds from the volatile oil could be determined and relative content of each compound was different. Forty-seven samples from different habitats with different phenotypes were divided to ten groups by between-groups linkage clustering method according to the active ingredients. All the accessions could be classified clearly. The cluster of accessions was associated with resource region. Asarum heterotropoides var. mandshuricum and Asarum sieboldii var. seoulense from the same origin were grouped together. Conclusion: There were much more differences in active ingredients content among Asarum resources which were in different regions cultivated with same way and environment with different phenotypes. We could select the perfect fundamental material according to the phenotypes and introduce germplasm from different regions for breeding and utilizing of Asarum. Most of samples clustered together associated with their origins instead of phenotype or specie.
