Background Dominant eye is one of the functional asymmetric organ,and the dfference between dominant eye and undominant eye is a researching hotspot.But the study about accommodation in adult myopia is less.Objective This study was to determine the association between ocular dominances and accommodative factors in the subjects with adult myopia.Methods This study used prospective descriptive research method.Thirty-five subjects aged from 18 to 35 years with the myopia ranged from-2.00 D to-10.00 D and anisometropia less than 1.5 D,BCVA≥ 1.0 were recruited consecutively in this study.Ocular dominance was determined using the hole-inthe-card test and thumb test.Refractive error was measured with objective and subjective optometry,and amplitude of accommodation was measured by push-up test.Fusion cross cylinder(FCC) was used to measure the accommodative lag,and flipper test was applied to determine the accommodative facility.Oral informed consent was obtained from each subject before any relevant examination.Results No significant differences were found in the amplitude of accommodation (D),accommodative facility (cpm) and accommodative lag (D) between the dominant eye and undominant eye (accommodative amplitude:9.69 D±2.30 D vs.9.60 D±2.37 D,P =0.294 ;accommodative facility: 11.08 D±4.20 D vs.10.63 D± 4.60 D,P=0.260;accommodative lag:P=0.141).In the patients with the right eyes as dominance eyes,the accommodative amplitude of both eyes were (9.48±2.29) cpm and (9.33 ± 2.49) cpm,and accommodative facility were (10.50 ± 4.70) cpm and (9.99 ± 4.90) cpm.There were no significant differences between the right and left eyes in the accommodative amplitude,accommodative facility and accommodative lag (P =0.319,0.116,0.590).In the patients with the left eyes as dominant eyes,the accommodative amplitude of both eyes were (9.91±2.35)D and (9.88±2.26) D,and accommodative facility were (10.70±3.77)cpm and (11.25 ±4.27) cpm.No significant differences were seen between the right eyes and left eyes in the accommodative amplitude,accommodative facility and accommodative lag (P =0.749,0.295,0.238).Conclusions The amplitude of accommodation of the dominant eye is not significantly enhanced,and less accommodative lag and better accommodative facility also are found in the demonstrate eye in myopia adults with low anisometropia.

OBJECTIVETo explore the better therapy in the treatment of ganglion.

METHODSNinety cases of ganglion were randomized into a two-way quintuple puncture group, a common quintuple puncture group and a fire needling group, 30 cases in each one. In the two-way quintuple puncture group, the "9-in-1" multiple penetrating needling technique was used. In the common quintuple puncture group, the traditional "5-in-1" multiple penetrating needling technique was applied. In the fire needling group, the traditional multiple fire needling technique was adopted. The treatment was given once a day, 3 treatments made one session and the efficacy was analyzed statistically after 1 session treatment in the three groups.

RESULTSAll of the three therapeutic methods achieved the efficacy on ganglion. The curative rate was 96. 7% (29/30) in the two-way quintuple puncture group, which was better obviously than 66.7% (20/30) in the common quintuple puncture group and 60. 0% (18/30) in the fire needling group (both P<0. 01).

CONCLUSIONThe two-way quintuple puncture technique achieves the remarkably superior efficacy on ganglion as compared with the common quintuple puncture technique and fire needling technique.

OBJECTIVETo observe the effect of Astragalus-Angelica Mixture (AAM) on osteopontin (OPN) expression in rats with chronic nephrosclerosis.

METHODSChronic nephrosclerosis model rats induced by repeated intraperitoneal injection of puromycin were randomly divided into the model group, AAM group and Irbesartan (an antagonist of angiotensin) group. The experimental course lasted 12 weeks. Blood and urine samples were examined by biochemical method. Kidney tissue was taken for pathological stain and immunohistochemical method and was applied to examine OPN expression, mononuclear macrophage, laminin in extracellular matrix and decorin expressions.

RESULTSAAM showed the effects of decreasing urinary protein and improving renal function similar to that of Irbesartan. It also could alleviate the pathological damage of kidney tissue, especially in decreasing renal tubular mesenchymal damage index. The accumulation of decorin and laminin in the mesenchymal extracellular matrix significantly decreased. Renal tubular OPN expression and mesenchymal infiltration of mononuclear macrophage decreased significantly and in a positive correlated manner (r = 0.885, P < 0.01).

CONCLUSIONAAM has similar renal protective action to that of Irbesartan, this action may be related to the inhibition of up-regulated OPN expression.

1,2,3,4,6-penta-O-galloyl-D-glucose (PGG) is one of the main active compounds of Guizhi Fuling capsule. Molecularly imprinted polymers (MIP) have high affinity toward template molecules synthesized by molecularly imprinted technology for its specific combined sites, which can overcome the shortcoming of traditional separation methods, such as complex operation, low efficiency, using large quantity of solvent and environmental pollution. In this paper, surface molecularly imprinted polymer (SMIP) was prepared by surface imprinting with PGG as the template molecule. Its adsorption capacity was measured by the scatchard equation. The separation of PGG from Guizhi Fuling capsule at preparatived scale was achieved with molecularly imprinted polymer as stationary phase and the purity was 90.2% by HPLC. This method can be used to prepare PGG from Guizhi Fuling capsule with large capacity and is easy to operate. It provides a new method for efficient separation and purification for other natural products.

The genomic DNA extracted from chicken embryo fibroblasts (CEF) of SPF chickens from three chicken farms was used as template to amplify the ALV proviral DNA by PCR with four pairs of primers, high positive detection rates of gag - gene (29/46), pol - gene (27/46), env - gene (24/46) and LTR fragment (31/46) were achieved. Eight continuous and overlapping fragments were amplified from one DNA sample with 8 pairs of primers according to published sequences, then cloned into the TA vector and se quenced. The complete sequence of the whole genome of ALV strain SD0501 was established and analyzed with DNAstar software. Comparisons of SD0501 sequence with that of other representative endogenous avian virus strains demonstrated that the genomes of ALV were relatively conservative, the nucleotide identity of all the strains was over 99.1%, and env - gene was over 98.5%. However, a low identity was demonstrated among the representative strains of different subgroups, especially, the env - gene showed obvious difference, the corresponding identity was as low as 56.3% - 91.5%.
