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 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.

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.

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.

To characterize the genomic sequence and arrangement of WU polyomavirus (WU virus) identified in clinical specimens collected from children with acute respiratory infections in Beijing, China, the sequences of capsid proteins VP1, VP2, and the large tumor antigen (LTAg), as well as the 5'-terminal sequence of WU virus, were amplified from the clinical specimen with ID number of BJF5276 which was determined as WU virus positive by PCR amplification. The PCR amplicons were sequenced, and genomic sequence analysis was performed by using the software DNAStar. In addition, VP2 coding-region sequences were amplified from other 21 clinical specimens identified as WU virus positive to investigate the gene diversity of WU virus. The genomic sequence of WU virus BJF5276 with accession number of HQ218321 in GenBank was 5,229 base pairs in length with 3 major coding domain sequences (CDS) sited on one strand coding for capsid proteins VP2, VP3 and VP1, and two CDS sited on the complementary strand coding for small tumor antigen (STAg) and LTAg; These 22 VP2 CDS sequences including 5 sequences submitted to GenBank were compared with 64 corresponding sequences downloaded from GenBank by MegAlign of DNAStar software, indicated that these sequences coming from children in Beijing shared high homology (over 98.8%) with those from GenBank. Phylogenetic analysis of these VP2 CDS by using Neighbor-joining (NJ) analyses with 2,000 bootstraps (Mega 4.0) showed that 20 sequences out of 22 belonged to clade Ia, and other 2 of them belonged to clade III, including 1 clustered in IIIa and 1 in a novel cluster proposed as IIIc. In conclusion, the genomic sequence of WU polyomavirus detected from clinical specimens from children in Beijing is closely related to other WU polyomaviruses in the feature of genomic coding region arrangement. Overall variation of VP2 CDS was very low, and there were different clades circulating in Beijing with a dominant clade Ia, which is different from dominated Ib circulating in other parts of the world reported previously, and a novel clade IIIc was proposed.
