Taking children respiratory infectious diseases as the research object, CDSS transform from isolated clinical data to an integration Model. With integrating pharmacy and laboratory knowledge, the system establishes children typical characterization data of common infectious diseases and medical efficacy data repository to providing treatment recommendations for doctor. Based on the clinical characteristics of children infectious diseases, this paper proposes knowledge inference engine and an information integration model. decision-making inference engine, medical information integration model.

OBJECTIVE: To study the characters of oscillatory potentials (OPs) of electroretinogram (ERG) after methanol intoxication in rats. METHOD: The SD rat models of methanol intoxication were established and divided into control group, 3-day intoxication group, 7-day intoxication group. The changes of OPs of ERG were recorded in a dark room. RESULTS: The total amplitudes of 3-day and 7-day intoxication groups decreased approximately 50% compared with that of the control group, while the schedule delayed approximately 16% and 61%, respectively. CONCLUSION The characters of methanol intoxication in rats included delay in schedule and decline in the total amplitude of OPs.

alphaB-crystallin is the structural protein of vertebrate lens, which is widely expressed in non-lens tissue. As one of the heat shock protein family members, alphaB-crystallin possesses biological properties of molecular chaperones and anti-apoptotic effects. Multi-factor injuries, such as retinopathy, inflammation and nervous system diseases, have a closely relationship with alphaB-crystallin. This paper reviews the research progress of the expression and mechanism of alphaB-crystallin in retina and extraocular tissues and organs.

OBJECTIVE: To compare the correlation between contrast vision (LV) and sweep visual evoked potential acuity (SVEP-A) among people with emmetropia, mild myopia, and moderate myopia. METHODS: The CV and SVEP-A were tested individually in 96 eyes from healthy young volunteers, including 37 eyes of emmetropia, 27 eyes of mild myopia, and 32 eyes of moderate myopia. The statistic analysis was done by ANOVA analysis and rank sum test. RESULTS: (1) With the decrease of contrast, CV and SVEP-A decreased in every group. (2) At 100% contrast, the difference of CV between emmetropia and mild myopia had statistical significance (P<0.05). At 100%, 25% and 10% contrast, the difference of CV between emmetropia and moderate myopia had statistical significance (P<0.05). (3) In the same group, the difference of 100% and 25% contrast had statistical significance (P < 0.05). So was between 100% and 10% contrast. (4) At 100% and 10% contrast, the difference of CV and SVEP-A had statistical significance (P < 0.05). CONCLUSION The CV of myopia relates to many factors including ametropia and fundus lesions. The correction of ametropia is important to the values of CV and SVEP-A.

In order to assess the effect of long-term versus short-term intravesical chemotherapy in preventing the recurrence of patients with non-muscle-invasive bladder cancer, we searched several databases with words as mesh terms and free text words to find all eligible randomized clinical trials (RCTs) for the comparison of the two strategies of instillation durations. "Observed-Expected events research (O-E)" and "Variance (V)" for calculating hazard ratio (HR) were used in Revman 5.2 software recommended by Cochrane Collabration for data analysis. Sensitivity and subgroup analysis were selected to minish heterogeneity. GRADEpro 3.6 profile recommended by Cochrane Collabration was employed for quality assessment of analyses. Finally, 13 eligible RCTs with 4216 patients were included in this review and 16 comparisons from 13 trials were involved for analysis. The pooled analysis revealed no significant difference between long-term and short-term duration [HR=0.99, 95% CI (0.89, 1.11), P=0.89]. Within the subgroup analysis, patients benefited from long-term instillations with a start regimen of one immediate instillation [HR=0.83, 95% CI (0.69, 1.00), P=0.05]. But patients were not suitable to receive long-term instillations with epirubicin (EPI) [HR=1.01, 95% CI (0.91, 1.13), P=0.78]. The progression rate was not reduced after long-term instillations [HR=0.96, 95% CI (0.66, 1.39), P=0.82]. From our results, patients should not receive introvesical chemotherapy more than half a year. In contrast, patients with one immediate instillation are preferred to have a long-term duration at least one year. Long-term instillations can not reduce the progression rate.

To screen and evaluate protein biomarkers for the detection of gliomas (Astrocytoma grade I-IV) from healthy individuals and gliomas from brain benign tumors by using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS) coupled with an artificial neural network (ANN) algorithm. SELDI-TOF-MS protein fingerprinting of serum from 105 brain tumor patients and healthy individuals, included 28 patients with glioma (Astrocytoma I-IV), 37 patients with brain benign tumor, and 40 age-matched healthy individuals. Two thirds of the total samples of every compared pair as training set were used to set up discriminating patterns, and one third of total samples of every compared pair as test set were used to cross-validate; simultaneously, discriminate-cluster analysis derived SPSS 10.0 software was used to compare Astrocytoma grade I-II with grade III-IV ones. An accuracy of 95.7%, sensitivity of 88.9%, specificity of 100%, positive predictive value of 90% and negative predictive value of 100% were obtained in a blinded test set comparing gliomas patients with healthy individuals; an accuracy of 86.4%, sensitivity of 88.9%, specificity of 84.6%, positive predictive value of 90% and negative predictive value of 85.7% were obtained when patient's gliomas was compared with benign brain tumor. Total accuracy of 85.7%, accuracy of grade I-II Astrocytoma was 86.7%, accuracy of III-IV Astrocytoma was 84.6% were obtained when grade I-II Astrocytoma was compared with grade III-IV ones (discriminant analysis). SELDI-TOF-MS combined with bioinformatics tools, could greatly facilitate the discovery of better biomarkers. The high sensitivity and specificity achieved by the use of selected biomarkers showed great potential application for the discrimination of gliomas patients from healthy individuals and gliomas from brain benign tumors.
