OBJECTIVE To investigate the correlative between anxiety and coping mode of parents of children with air way foreign bodies. METHODS Self-rating anxiety scale (SAS) and simplified coping style questionnaire (SCSQ) were used to investigate the anxiety level and coping mode among 212 parents of children with airway foreign bodies. RESULTS The SAS scores of parents of children with airway foreign bodies was considerably higher than China normal, there was significant difference between the two (P <0.01), the positive coping style score was higher (P<0.05), while the negative coping style score was lower than the normal (P <0.01). The SAS score was significantly and positively related to the negative coping style score (P<0.01), and not related to the positive coping style score (P>0.05). CONCLUSION The parents of children with airway foreign bodies have higher anxiety level than the norm, they often take an positive coping style.

Objective:To establish a method for the determination of related substances in erythromycin ophthalmic ointment. Methods:The extraction method was established and optimized. An HPLC gradient elution method was used for the determination of related substances in erythromycin ophthalmic ointment. Results: One step extraction with PBS (pH 7.0) - methanol(1: 1) had promising effect. After the method validation, it was proved that the method could be used to determine the related substances in eryth-romycin ophthalmic ointment. Conclusion:The method established in the paper provides a better analytical extraction and determina-tion method for the quality control of erythromycin ophthalmic ointment.

OBJECTIVETo study the anti-immune inflammation efficacy and toxicity of Tripterygium wilfordii decoction, in order to provide experimental basis for studies on its "efficacy-toxicity" correlation.

METHODThe delayed hypersensitivity model was established by dinitrofluorobenzene in mice. Different doses of T. wilfordii decoction was administered for 5 consecutive days. The ear swelling inhibition ratio and the toxic action were observed. After the final administration, the biochemical indexes of PGE2, TNF-α, IL-2, ALT, AST, PA, TBA, TBIL in serum were detected, and the visceral indexes of heart, liver, spleen and kidney were measured.

RESULTThe DNFB-induced ear swelling could be notably inhibited by multiple oral administration of T. wilfordii decoction, with the ED50 and its 95% confidence limit of 0.34 (0.21-0.42) g x kg(-1). The contents of PGE2, TNF-α, IL-2 in serum decreased in a dose-dependent manner. The activities of serum AST, ALT, TBA, TBIL and the PA content reduced.

CONCLUSIONT. wilfordii decoction shows a significant anti-immune inflammation efficacy within the dosage range between 0.59 and 2.34 g x kg(-1) in a dose-dependent manner. With a certain hepatotoxicity, high dose (2.34-4.68 g x kg(-1)) of T. wilfordii decoction can cause substantial liver injury, with a dose dependence in liver function index. Therefore, the efficacy and toxicity of T. wilfordii is dose dependent, which provides reference for preventing adverse drug reactions in clinic and developing early-warning schemes and ensure the clinical medication safety of T. wilfordii.

Objective To compare four pretreatment methods of human plasma coagulation factor Ⅷ( FⅧ) before column purification.Methods Cryoprecipitate was dissolved in Tris , before the supernatant was treated with glycine precipitation, PEG precipitation, acid precipitation and aluminum hydroxide gel adsorption , respectively.Activated partial thromboplastin (APTT) was used to measure the activity of the supernatant clotting FⅧ after treatment.The total activity recovery and specific activity of the final samples were used to weigh the efficacy of those methods .The purity of the intend-ed protein was estimated by non-reducing SDS-PAGE electrophoresis .Results Total activity recovery of glycine precipitati-on was the highest (94.00%±7.60%), followed by that of acidic precipitation (89.47%±2.60%) and PEG precipita-tion (80.92%±9.67%) methods.The lowest was aluminum hydroxide gel adsorption (78.65%±7.52%).Glycine precipitation and PEG precipitation could more effectively remove contaminating protein than acid precipitation and aluminum hydroxide gel adsorption .Treated by four different methods , the specific activity of FⅧ of glycine precipitation sample was the highest (0.6856 ±0.1258 IU/mg), followed by PEG precipitation (0.5773 ±0.0787 IU/mg) and acidic precipitation (0.3885 ±0.0301 IU/mg).The specific activity of aluminum hydroxide gel adsorption was the lowest (0.2879 ±0.0472 IU/mg).Conclusion PEG precipitation is more effective for the actual production process than the other three methods .

Objective To investigate the risk factors for early neurological deterioration (END) in patients with ischemic stroke. Methods The consecutive patients with new acute ischemic stroke within 24 h were enrol ed. They were divided into either an END or a non-END group. Their relevant medical history, baseline clinical data, imaging examinations and laboratory test results in both groups were compared. Results A total of 95 patients with acute ischemic stroke were enrol ed, including 32 in the END group and 63 in the non-END group. There were significant differences in the proportion of patients in diabetes mel itus (χ2 =6. 081, P=0. 014), baseline National Institutes of Health Stroke Scale (NIHSS) score >15 (χ2 =9. 851, P=0. 002), baseline infarct volume >30 cm3 (χ2 =10. 815, P=0. 001), and fever (χ2 =6. 642, P=0. 010), as wel as the fasting glucose (t=2. 632, P=0. 010), homocysteine (t =2. 997, P=0. 003), C-reactive protein (t=2. 349, P=0. 021), baseline NIHSS (Z=497. 5, P=0. 001), and baseline infarct volume (Z=544. 5, P<0. 001) between the 2 groups. Furthermore, there were significant differences in the proportions of patients in large artery atherosclerotic stroke (χ2 =24. 539, P<0. 001 ) and smal arterial occlusive stroke (χ2 = 27. 913, P< 0. 001 ) in the TOAST classification, as wel as the total anterior circulation stroke (χ2 =7. 578, P<0. 006) and partial anterior circulation stroke (χ2 =4. 818, P<0. 028) in the OSCP classification. Multivariate logistic regression analysis showed that fasting glucose >6. 0 mmol/L (odds ratio [OR] 6. 951, 95%confidence interval [CI] 2. 159-22. 348; P=0. 001), homocysteine >15 μmol/L (OR 3. 301, 95% CI 1. 028-10. 595; P=0. 045), NIHSS score >15 (OR 4. 174, 95% CI 1. 772-14. 870;P=0. 028), infarct volume >30 cm3 (OR 4. 996, 95% CI 1. 334-18. 717; P=0. 017), and fever (OR 4. 528, 95% CI 1. 334-15. 372;P=0. 015) were the independent risk factors for occurring END in patients with acute ischemic stroke. Conclusions The baseline glucose, NIHSS score, infarct volume, homocysteine, and increased body temperature are the independent risk factors for occurring EDN in patients with acute ischemic stroke.

Objective To investigate the relationship between the apoptosis,expressions of Bcl-2 and Bax protein in perihematomal brain regions of rats and neurologic dysfunctions after intracerebral hemorrhage (ICH). Methods Seventy Sprague-Dawley rats were divided randomly into two groups:an experimental group and a control group.A model of ICH was established by injection of 0.5 U bacterial collagenaseⅦinto the caudate nucleus in the rats.Neurological impairment was evaluated at 6 h,12 h,24 h,48 h,72 h,7 d and 14 d after 1CH,respectively, before the rats were sacrificed.TUNEL method was used to detect apoptosis,and SP method to detect expressions of Bcl-2 and Bax protein in the perihematomal brain tissues.Results Neurological impairment occurred in all the rats after ICH,and peaked at 48 h after ICH.The apoptosis and expressions of Bcl-2 and Bax protein were peaked at 48 h,6 h and 48 h after ICH,respectively.Conclusion The degree of the neurological impairment after ICH is parallel to that of the apoptosis.Apoptosis may play an important role in neurological impairment after ICH.
