Objective To study the prospective memory and the severity of the impairment of event- based prospective memory(EBPM)and time-based prospective memory(TBPM)in normally aging adults. Methods We set a neuropsychological battery to measure the education-matched 40 adults and 40 normally aging adults who were given EBPM and TBPM tasks.Results Compared with the young controls(EBPM, 6.25?1.60;TBPM,5.38?0.87),both EBPM(2.50?0.85)and TBPM(4.93?1.07)in the elderly had been impaired,especially EBPM(t = 13.117,P

Objective To analyze the concentration of epithelial cell derived neutrophil-activating protein 78(CXCL-5) in the sy-(novial) fluid(SF) and peripheral blood in children with rheumatoid arthritis(RA) and evaluate its clinical relevance to the disease development.Methods SF and peripheral sera were taken from 26 children with RA and 16 healthy controls,and CXCL-5 was measured by enzyme linked immunosorbent assay(ELISA).CXCL-5 in SF was also measured in RA children after receiving steroid treatment.Results The levels of CXCL-5 was significantly higher than that in the SF of RA children compared with healthy controls(P0.05).Interestingly,CXCL-5 markedly decreased in RA children after steroid treatment(P

Objective: To explore the treatment effect of sticking-needle acupuncture plus tendon-regulating manipulation on pain, swelling and joint dysfunction due to acute ankle sprain.Methods: A total of 80 patients with acute ankle sprain were recruited and divided into a control group and a treatment group according to the random number table method, with 40 patients in each group. Both groups received the same conventional interventions. The control group was treated with additional tendon-regulating manipulation, and the treatment group was treated with tendon-regulating manipulation plus sticking-needle acupuncture. The pain, swelling and joint dysfunction of the ankle were observed in both groups before and after 3 d, 7 d and 14 d of treatment. Results: Before treatment, there was no statistically significant difference in the visual analog scale (VAS) score of pain between the two groups (P>0.05). After treatment, the VAS scores of both groups showed a decreasing trend over time, and the differences within the groups were statistically significant (P<0.05). After 3 d, 7 d and 14 d of treatment, the VAS scores in the treatment group were lower than those in the control group, with statistically significant differences (P<0.05). Before treatment, there was no statistically significant difference in the degree of swelling between the two groups (P>0.05). After treatment, the degrees of swelling in both groups showed a decreasing trend over time, and the differences within the groups were statistically significant (P<0.05). After 3 d and 7 d of treatment, the degrees of swelling in the treatment group were lower than those in the control group, with statistically significant differences (P<0.05). There was no statistical difference in the degree of swelling between the two groups after 14 d of treatment (P>0.05). Before treatment, there was no statistically significant difference in the American Orthopedic Foot Ankle Society (AOFAS) ankle-hindfoot scale score between the two groups (P>0.05). After treatment, the AOFAS ankle-hindfoot scale scores of both groups showed an increasing trend over time, and all the differences within the groups were statistically significant (P<0.05). After 3 d, 7 d and 14 d of treatment, the AOFAS ankle-hindfoot scale scores in the treatment group were higher than those in the control group, with statistically significant differences (P<0.05). Conclusion: Based on the routine intervention, the addition of sticking-needle acupuncture and tendon-regulating manipulation was better in alleviating pain and swelling and improving joint function in patients with acute ankle sprain than the addition of tendon-regulating manipulation alone.

AlM: To evaluate the effect of rigid gas permeable contact lens ( RGP ) in correcting high myopia and astigmatism.METHODS: Forty-one patients ( 65 eyes ) with myopia (-9. 03 ± 6. 19DS, maximum -23. 00DS) and astigmatism (-1. 41 ± 1. 32DC, maximum -5. 50DC) were fitted with RGP after strict routine ophthalmological examination, objective refraction and subjective refraction. All these patients were followed after 1wk, 1, 3mo and half one year.RESULTS:Sixty-five eyes were fitted with RGP (-9. 92± 5. 96DS). RGP base curve ( BC) was majorly located within the range 7. 20 ~8. 25mm. 46. 2% eyes with RGP achieved 1. 0 ( BCVA ) and 80. 1% achieved above 0. 6 ( BCVA) . However, with spectacles, the percent was 28%(1. 0) and 60% (>0. 6), respectively. BCVA of RGP was 0. 81 ± 0. 22, but BCVA with spectacles was 0. 66 ± 0. 28, there was statistical significance (P<0. 01). There were 40 eyes (62%) fitted with RGP whose vision were enhanced more than 1 line, 24 eyes ( 37%) whose vision were not changed and 1 eye (2%) whose vision were dropped 1 line.CONCLUSlON:RGP effectively improves visual acuity of high myopia and astigmatism compared with spectacles.

Objective To study the potential role of tumor necrosis factor-α (TNF-α) induction in the development of mucosal barrier dysfunction in rats caused by acute intestinal ischemia-reperfusion injury, and to examine whether pretreatment with monoclonal antibody against TNF-α (TNF-α MoAb) would affect the release of D(-)-lactate after local gut ischemia followed by reperfusion. Methods Anesthetized Sprague-Dawley rats underwent superior mesenteric artery occlusion for 75 min followed by reperfusion for 6 hr. The rats were treated intravenously with either TNF-α MoAb (20 mg/kg) or albumin (20 mg/kg) 30 min prior to the onset of ischemia. Plasma D(-)-lactate levels were measured in both the portal and systemic blood by an enzymatic spectrophotometric assay. Intestinal TNF-αmRNA expression as well as protein levels were also measured at various intervals. In addition, a postmortem examination was performed together with a macropathological evaluation based on a four-grade scoring system.Results Intestinal ischemia resulted in a significant elevation in D(-)-lactate levels in the portal vein blood in both the control and treatment groups ( P ＜0.05). However, animals pretreated with TNF-α MoAb at 6 hr after reperfusion showed significant attenuation of an increase in both portal and systemic D(-)-lactate levels when compared with those only receiving albumin (P ＜ 0.05). In the control animals, a remarkable rise in intestinal TNF-α level was measured at 0.5 hr after clamp release ( P ＜ 0.01); however, prophylactic treatment with TNF-α MoAb completely annulled the increase of local TNF-α levels seen in the control animals. Similarly, after anti-TNF-α MoAb administration, intestinal TNF-α mRNA expression was markedly inhibited, which showed significant differences when compared with the control group at 0.5 hr, 2 hr and 6 hr after the release of occlusion ( P ＜ 0.05-0.01 ). In addition, the pathological examination showed marked intestinal lesions that formed during ischemia, which were much worse upon reperfusion,particularly at the 6 hr time point. These acute injuries were obviously attenuated in animals receiving TNF-α MoAb.Conclusions It appeared that acute intestinal ischemia was associated with failure of the mucosal barrier, resulting in increased plasma D(-)-lactate levels in both portal and systemic blood. These results suggest that TNF-α appears to be involved in the development of local damage associated with intestinal ischemic injury. Moreover, prophylactic treatment with TNF-α MoAb exerts preventive effects on ischemia/ reperfusion-induced circulating D (-)-lactate elevation and gut injury.

Bicyclol with benzyl alcohol structure, is a poorly water-soluble drug, used for the treatment of chronic hepatitis B. To increase the drug solubility and oral bioavailability, a Bicyclol-phospholipid complex was studied on its preparation, formation mechanism, and the influence on drug physicochemical properties and oral absorption. The complex was prepared by a solvent evaporation method. The optimal formulation was selected by orthogonal experimental design, and a reasonable evaluating method of the complexation rate was established. Various methods, such as differential scanning calorimetry (DSC), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and 31P nuclear magnetic resonance (31P-NMR), were used to explore the phase state and formation mechanism of the complex. The solubility of drug in complex was investigated in water/n-octanol. Preliminary study of its absorption and liver tissue distribution in rats was also carried out. The results showed that Bicyclol and phosphatidylcholine can be complexed entirely in the molar ratio 1 : 2. Bicyclol was dispersed in phospholipids as amorphous state. They were combined by intermolecular hydrogen bond due to charge transfer effect which occurred between the two polarities of the double bond between phosphorus and oxygen (P=O) of phosphatidylcholine and benzalcohol group of Bicyclol. The solubility of the complex compared to the active pharmaceutical ingredient (API) was effectively enhanced 5.75 times in water and 7.72 times in n-octanol, separately. In addition, drug concentrations were also enhanced 43 times in plasma and 13 times in liver with one hour after administering the complex to rats via oral gavage. All of these indicated that Bicyclol with benzalcohol group can interact with phospholipids to form complex, improving drug's physicochemical properties, thus further increasing its absorption and target tissue distribution. This study also provided theoretical reference for the research of other benzalcohol derivatives complexed with phospholipids.
