International Eye Science 2011;11(5):757-759
AIM:To compare the efficacy of three types of eye care (artificial tear, moist chamber and polyethylene covers) for preventing exposure keratopathy in intensive care patients.METHODS: Intensive Care Unit (ICU) patients were randomly divided to three treatment groups, including artificial tear group(29 cases), moist chamber group (27 cases) and polyethylene covers group (28 cases). Patients in artificial tear group received two drops of carboxymethylcellulose dropped to each eye every 2 hours. The moist chamber and polyethylene covers groups were changed every 12 hours or as needed if they became unclean or torn. Corneal fluorescein stain was performed daily.RESULTS:No one in the polyethylene covers group and one case(4%) in the moist chamber group had exposure keratopathy compared to 8 cases (28%) in the artificial tear group. There were statistical significance differences between both artificial tear group and moist chamber group (P=0.02), artificial tear group and polyethylene covers group (P=0.003). Everyday time of eye care in the artificial tear group, the moist chamber group and the polyethylene covers group was respectively 26.69±2.39, 35.33±2.63 and 7.48±0.87 minutes. Everyday time of eye care in the polyethylene covers group was statistically more time-saving than that in the artificial tear group (P<0.01) and the moist chamber group (P<0.01). CONCLUSION: Polyethylene covers are more effective and time-saving in reducing the incidence of corneal damage in intensive care patients.

Methods The core authors, coauthors and their organizations whose articles were published in Chinese Journal of Orthopaedics between 1995 and 2004 were quantitatively analyzed using literature search through CMCI, which programmed by the People's Liberation Army Medical Library and their geographical regions distribution, the organizations of whom had high quantitative publication were determined using literature metrology methods. Results There were 2660 articles published in Chinese Journal of Orthopaedics between 1995 and 2004. All of 1123 authors of 2660 articles had only one article published which accounted for 69.67% of total first authors on the Chinese Journal of Orthopaedics in ten years. There were 2385 articles with one or more coauthors and the cooperative rate was 89.66%, and cooperative degree was 4.11 in the period of time. There were 275 articles with single author, which accounted for 10.34% of total articles. The articles written by the authors from military hospitals, university affiliated hospitals and provinces-level hospitals were 646(24.28%), 1091(41.01%) and 706(26.54%), respectively during the period. There were 218 core authors with 959(36.05%) articles published and there were 20 high-quantities organizations with 1007(37.86%) articles published in this study. The number one region of published articles was Beijing with 667(25.08%) articles. There were 2443 (91.84%) articles pressed from the organizations of affiliated hospitals of universities, provinces-level hospitals and army hospitals. Among them, Tianjin hospital (101 articles), Beijing Jishuitan hospital (100 articles) and affiliated Xijing hospital of the 4th military medical mniversity (79 articles) occupied 10.53% of the pressed papers and they were in the first three positions. Conclusion Authors of Chinese Journal of Orthopaedics have a wide distribution and highly cooperative rate. There were a group of active and talented core authors who has a great influence on the journal.

Objective To introduce a new method of septal cartilage augmentation for hump nose plasty. Methods The section of septal cartilage was collected and divided into two or three parts. The grafts were sutured by means of a mattress suture, and placed over the dorsum of superior and inferior hump. The dorsum became flat and straight immediately afterward. Results After a short term and long term follow up, 30 patients who underwent this operation were satisfied the operative results. Conclusion Septal cartilage augmentation for hump nose plasty is an efficient new method.

Objective To investigate the alteration of aquaporin 1(AQP1) expression in lung tissues in hemorrhage-lipopolysaccharide(LPS) two-hits rats and the effects of panaxadiols(PDS)and dexamthasone(Dex) on it.Methods The rat model of acute lung injury was built with hemorrhage-LPS two hits.The experiment was divided into control group(S),two-hits model group(HL),DEX group(HLD),and PDS group(HLP).The pathological changes of lung tissue were examined by HE staining.The expression of AQP1 was analyzed by RT-PCR,Western blotting and immunohistochemical staining.Results ① Significant inflammatory changes in pulmonary interstitial of rats in HL group were observed.However,in HLD group and HLP group,the pulmonary pathologic changes were much slighter.② AQP1 mRNA and protein expressions in lung tissues in HL group were significantly decreased compared with others groups(P

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.
