This study explored the accuracy of using visual evoked potentials (VEP) technology for visual acuity estimation. The enrolled 726 patients with post-traumatic unilateral decrease in visual acuity included the injured eyes served as the experimental group, and the healthy eyes as the control group. The least signal visual angle (LSVA), and amplitude and latency of P(100) were chosen as test indexes. The results under different experimental conditions were recorded by PRVEP technology. All data collected were processed and analyzed by SPSS software. The results showed that the coincidence between subjective and VEP visual acuity was 96.7% in control group, but there was very significant difference in experimental group. It was concluded that with the regression formulation for the amplitude of P(100) and vision under LSVA, visual acuity can be estimated more accurately and impartially.

Objective To investigate the effects of penehyclidine hydrochloride (PHCD) on acute lung injury (ALI) induced by blunt chest trauma and Toll-like receptor 4 (TLR4) expression in the lung tissues in rats.Methods Ninety-six male SD rats weighing 250-300 g were randomly divided into 3 groups ( n = 32 each):control group (group C), ALI group and PHCD group. ALI was induced by dropping a 300 g weight onto a precordial protective shield to direct the impact force away from the heart and toward the lungs in anesthetized rats according to the method described by Raghavendran et al. PHCD 2 mg/kg was injected intraperitoneally immediately after ALI was induced in group PHCD. Eight rats were selected at 2, 8, 12 and 24 h after ALI was induced, and arterial blood samples were collected for determination of the serum TNF-α concentration. Eight rats were selected at 8 h after ALI was induced, arterial blood samples collected for blood gas analysis and then the rats sacrificed. The lungs were immediately removed for determination of W/D lung weight ratio, myeloperoxidase (MPO) activity and TLR4 expression, and microscopic examination. Results The pH value and PaO2 were significantly lower, and the PaCO2, lactic acid level, MPO activity, W/D ratio, TLR4 expression and serum TNF-α concentration higher in groups ALI and PHCD than in group C (P < 0.01 ). The pH value and PaO2 were significantly higher, and the PaCO2, lactic acid level, MPO activity, W/D ratio, TLR4 expression and serum TNF-α concentration lower in group PHCD than in group ALI ( P < 0.05). The lung histopathologic damage was significantly ameliorated in PHCD group as compared with ALI group. Conclusion PHCD can protect the lungs against blunt chest trauma-induced ALI, and the down-regulation of TLR4 expression in lung tissues and reduction of inflammatory response are involved in the mechanism.

Aim To develop a rapid and inexpensive method for purification of human albumin, a method of immunomagnetic microspheres (IMMS) based on enzyme-linked immunosorbent assay (ELISA)for the purification of human albumin from human serum. Methods Polystyrene magnetic microspheres with carboxyl groups as carriers were prepared, and then the carboxyl groups on the surface of the microspheres were activated by ethylcarbodiimide (EDC). Finally rabbit anti-human serum albumin (HSA) antibodies were covalently bound to it and the complex can specifically capture HSA. After the procedure of capturing HSA, through taking rabbit anti-human albumin protein antibodies as a capture antibody, and goat anti-human albumin protein antibodies as a detection antibody, an ELISA on IMMS was developed, which can determine the recovery yield of HSA from the human serum. Results The result of the experiment was that the recovery of human albumin with IMMS was (86 ± 4) % , and IMMS were reused for two other purifying cycles, the results of which were (69.0 ± 0.6) % and (40.8 ± 0.8) % , and the purity of the product was about 90%. Conclusion The results above prove that the immunomagnetic purifiying strategy was shown to be efficient and offers an new thought for a large scale production of highpurity HSA.
