Objective To focus on the expressiveness and flexibility of OpenSDE: an application that supports recording of structured narrative data. Methods OpenSDE enabled data entry with (customizable) forms based on trees of medical concepts. The relevant scope for data entry could be tailored per medical domain by construction of a domain-specific tree. OpenSDE was intended for structuring narrative data to make these available for both care and research. Results The OpenSDE application was used at two departments in aspects of radiology, neurology, pediatrics, and child psychiatry. Conclusion OpenSDE is superior to traditional text entry method in aspects of correct and full expression and clinical decision support.

Objective To further develop SDE for structured documentation of clinical data based on medical ontology. Methods OpenSDE was customized for the broad domain of medical ontology: medical concepts and its descriptors from history taking and physical examination were modeled into a tree structure. Results An expandable EMR system with structured data entry was developed. Conclusion Structured data entry is significant to clinical decision based on EMR.

Ocular albinism type 1 (OA1),the most form of the ocular albinism,is an X-linked disorder mainly characterized by a severe reduction of visual acuity,hypopigmentation of the retina,photophobia,strabismus and nystagmus. The OA1 gene is located on chromosome Xp22.32 and the coding sequence is divided into nine exons. The OA1 gene codes for a 404 amino acid protein thought to be a melanosomal transmembrane glycoprotein. The OA1 protein is similar to the G protein-coupled receptors,but it's exact function is not clear. There are many mutations and deletions of the OA1 gene have been found.

Objective To evaluate the effect of dexmedetomidine on lung injury induced by extremity ischemia-reperfusion.Methods Forty patients,aged 18-60 yr,with body mass index of 20-25 kg/m2,of ASA physical status Ⅰ or Ⅱ,with 1 h ≤ predicted duration of surgery ≤ 1.5 h,were randomly divided into 2 groups (n =20 each) using a random number table:control group (group C) and dexmedetomidine group (group D).In groupD,dexmedetomidine 1 (g/kg was infused intravenously for 10 min,followed by continuous infusion of dexmedetomidine at 0.5 μg· kg-1 · h-1 until the end of the surgery,while in group C the equal volume of normal saline was given instead.Immediately before induction of anesthesia (T1,baseline),at 60 min after tourniquet was inflated (T2) and at 30 min,2 h and 6 h after tourniquet release (T3-5),blood samples were collected from the radial artery for blood gas analysis and for measurement of the levels of plasma interleukin-6 (IL-6),IL-8,tumor necrosis factor-α (TNF-α),malondialdehyde (MDA) and superoxide dismutase (SOD),and arterial partial pressure of oxygen (PaO2) and partial pressure of carbon dioxide (PaCO2) were recorded.Alveolar-arterial oxygen difference (A-aDO2) and respiratory index (RI) were calculated.Results Compared with group C,PaO2 was significantly increased at T5,and A-aDO2 and RI at T5,the levels of plasma IL-6 and IL-8 were decreased at T4,5 and the levels of plasma TNF-α,MDA and SOD were decreased at T3-5 in group D.Conclusion Dexmedetomidine can attenuate lung injury induced by extremity ischemia/reperfusion via inhibiting inflammatory responses and lipid peroxidation.

The solvent sublation technique was applied for the separation and enrichment of L-Arg using dodecylbenzene sulfonic (DBSA) as the surfactant, di (2-ethylhexyl) phosphoric acid (P204) as the extractant and n-heptane as the organic solution. The solvent sublation was compared with the floatation complexation extraction, foam floatation and solvent extraction. The experimental results showed that enrichment ratio of 16.2 and removal rate of 97.2% to L-Arg were obtained by the solvent sublation under the conditions of room temperature, 0.09 g/L L-Arg aqueous solution 250 mL, DBSA concentration 0.15 g/L, the initial pH 7.0, volume of n-heptane 10 mL, volume of P204 4.5 mL, gas flow rate of 200 mL/min. The study of the kinetics indicated that the solvent sublation process could be divided into three stages distinctly. The processes of the first stage and the second stage followed the first order kinetics equation; the process of the third stage followed the zero order kinetics equation. The separation mechanism of solvent sublation was also discussed.

BACKGROUND: Constipation, especially that caused by spleen insufficiency in transportation, often not responses to common purgatives, however,the therapy to strengthen the spleen and regulate qi so as to promote transportation and dredge stasis may be an ideal way to resolve the problem.OBJECTIVE: To investigate the effect of zhizhu decoction, a classic famous prescription, on gastric motility of mice with spleen insufficiency constipationDESIGN: A randomized controlled trial.SETTING: Department of Traditional Chinese Medicine (TCM) of Guangdong Medical College and Spleen-stomach Institute of Guangzhou University of Traditional Chinese Medicine.MATERIALS: The experiment was completed from June to December2002 at Spleen-stomach Institute of Guangzhou University of Traditional Chinese Medicine. Totally 328 NIH mice of general grade were chosen.METHODS: Mouse models with spleen insufficiency constipation were set up by irregular diet and overstrain combined with water deprivation. The influence of zhizhu decoction in large, middle and small doses on defecation in both spleen insufficiency mice and normal mice was investigated, taking Chinese patent drug bianmi tong (bowel-relaxing) as a positive control. In observation of normal mice defecation, there were five groups of large dose,middle dose and small dose of zhizhu decoction, bianmi tong and normal control. In observation of defecation of spleen insufficiency constipation mice, there were six groups: the above five and a natural recovering. In observation of loading mice trial, besides the above five groups, there was an atropine group. After administration, the time when the mice first defecated dark stool, the number of stool grains and the stool quantity were observe;and the percentage of small intestine advance was calculated.MAIN OUTCOME MEASURES: [1] Observation of the effect of zhizhu decoction on the defecation in both normal and spleen insufficiency mice.[2] The influence of zhizhu decoction on bowel advance in both normal and atropine loading miceRESULTS: Totally 328 mice were involved in the trial and 319 entered into the final result analysis, the other 9 died because of mistake in administration by gavage. The effect of zhizhu decoction on the defecation: [1] For normal mice, compared with the distilled group, in the zhizhu decoction groups of various doses the time when the mice first defecated dark stool was obviously reduced, and the number of stool grains and stool quantity were obviously increased, but the effect in the large and middle dose groups was best. [2] Compared with the normal group, in the model group the time when the mice first defecated dark stool was obviously increased, and the number of stool grains and stool quantity were obviously decreased. Zhizhu decoction in large and middle doses could obviously reduce the time when the mice first defecated dark stool, and increase the number of stool grains and stool quantity, the effect was better than that of the control drug bianmi tong. The influence ofzhizhu decoction on intestinal advance in mice: [1]Zhizhu decoction in various doses could obviously increase the rate of intestinal advance compared with distilled water group for normal mice. [2]Adding atropine load could reduce the rate of intestinal advance compared with the normal control group, and the percentage in all zhizhu decoction groups was obviously increased compared with the atropine group.CONCLUSION: Zhizhu decoction can reduce the time when the mice first defecated dark stool, increase the number of stool grains and stool quantity were obviously increased to both normal mice and mice with spleen insufficiency mice; it can also increase the intestinal advance rate in normal mice, and had a good antagonism against the inhibition of atropine to intestinal advance. In the trials the effect of zhizhu decoction in large and middle doses was more obvious, with a certain dose-effect relationship, the effect was better than that of the control drug bianmi tong.
