Objective To research patients with ophthalmologic perioperative information systems, strengthening the information management of nursing work, achieving consensus and sharing of health care information resources, and then to explore the clinical application effects of this ophthalmologic peri- opera-tive information systems. Methods The convenient sampling method was used in the study. The control group was consisted of 1 740 patients in our hospital from January to March 2013 (before the application of ophthalmologic perioperative information systems). The observation group included 2 078 patients of the same hospital (after the application of ophthalmologic perioperative information systems). The control group adopted routine pre- operative information acquisition method, the observation group applied ophthalmologic perioperative information systems, which included input function, reading function and statistical function. The incidence rate of canceled operation and satisfaction were compared between two groups. Results Ophthalmologic peri- operative information systems provided patients with information gathering, query and analysis in different periods. The rate of the canceled operation reduced in the observation group from 3.74% (65/1 740) to 2.69% (56/2 078) in the control group, χ2=3.91, P<0.05. The satisfaction degree increased from 91.84 % (1 598/1 740) in the observation group to 96.78% (2 011/2 078) in the control group, χ2=44.60, P<0.05, the difference was statistically different. The hospitalization days from April to September in 2013 shortened compared with those of the same period in 2012. Conclusions Ophthalmologic peri- operative information systems promotes the scientific and informatization of nursing information, which is worthy of wide clinic application.

Objective To investigate the epidemiological characteristics of tuberculosis (TB)in children in Chongqing and provide a data support for the establishment of children tuberculosis prevention and control strategy.Methods The TB data of chil-dren aged between 0 to 14 from 2009 to 2013 was analyzed.Results The average prevalence rates and registration rate of TB in children were 7.22/ 100 000 and 4.48/ 100 000,respectively.The cases mainly concentrated between10 to 14 years old.The epi-demic situation in southeast of chongqing was higher.And most of them were secondary tuberculosis of lung.The cases were mainly detected in referral,follow and clinical consultation.Conclusion The prevalence of TB in children of Chongqing was serious.It should take comprehensive measures to strengthen the prevention and control of children tuberculosis.

Objective To investigate the abilities of emotion recognition and social cognition in patients with idiopathic epilepsy and further explore the factors related to the impairments.Methods After 24-hour EEG monitoring,70 people with idiopathic epilepsy were administered with a neuropsychological battery for basic cognitive assessment and then were tested with the Eye Basic Emotion Discrimination Task (EBEDT) and the Eye Complex Emotion Discrimination Task (ECEDT).Results Compared with health controls,people with epilepsy got significantly lower score in recognizing happy (19.3±2.0 vs 19.9±0.2),angry (17.9±2.0 vs 18.9±1.0),sadness (18.1±2.3 vs 19.2±1.0),fear (16.4±1.9 vs 17.6±1.3),disgust (17.6±2.1 vs 18.6±1.2) and surprise (18.3±1.5 vs 19.1±1.1) (P＜0.05,respectively),as well as complex emotions ((23.3±4.2) vs (27.1±2.8),P＜0.05).There was no significant difference between the two groups in gender recognition (P＞0.05).Significant positive correlation was found between the total score of basic emotions and the mind reading (r=0.444,P=0.000) in the patient group.Correlation analysis revealed significant relation between the total correct number of emotion recognition and the level of anxiety,depression and the executive function in epilepsy group (P＜0.05,respectively).Significant associations were found between the ECEDT and the Digital Span test,the Stroop test,Beck Depression Index and Hamilton Anxiety Scale (P＜0.05,respectively).Conclusion People with epilepsy have general impairments of emotion recognition and theory of mind,the impairments may be associated with the state of mood disorder and the weakened executive function.

Objective To observe the inhibitory effect of atorvastatin on bleomycin-induced pulmonary fibrosis in SD rats and study their possible mechanism.Methods 30 male SD mice under SPF condition with average body weight of 250g were randomly allocated to three groups (n =10,each) of saline control group (control group),bleomycin-induced pulmonary fibrosis group (pulmonary fibrosis group) and atorvastatin treatment group (treatment group).Bleomycin (5mg/kg) (versus 0.2 ml saline in control group) were endotracheally instilled in pulmonary fibrosis group and the treatment group in order to establish the model of pulmonary fibrosis.Subsequently,the rats in the treatment group received daily atorvastatin (10 mg/kg) orally.5 rats in each group were sacrificed on 7th and 28th day after intratracheal instillation.Their lung tissues were taken and tested.The histological changes in the lungs were evaluated by hematoxylin-eosin and masson stain.The tumor necrosis factor (TNF-α) level and hydroxyproline content in lung tissues were measured by enzymelinked immunosorbent assay (ELISA).The expressions of Kruppel-like factor 2 (KLF2) protein and mRNA in lung tissues were measured by Western blotting and Real-Time PCR.Results The lung tissue in model group had significant bleeding and oozing inflammatory response on the 7th day and pulmonary fibrosis on the 28th day.Bleeding and oozing inflammatory response and pulmonary fibrosis were subdued in treatment group on the same days as compared to the model group.Hydroxyproline and TNF-α contents in lung tissue were significantly higher in model group than in control group (both P＜0.05).KLF2 protein and KLF2-mRNA expressions in lung tissues were significantly lower in model group than in control group (both P＜0.05).The above changes were partially reversed in treatment group.Compared to model group,treatment group showed that hydroxyproline and TNF-α contents in lung tissues were significantly reduced (both P＜0.05) and KLF2 protein and KLF2 mRNA expressions in lung tissues were significantly increased (both P＜ 0.05).Conclusions Atorvastatin can reduce the secretion of TNF-α and alleviate bleomycin-induced pulmonary fibrosis.The mechanism inhibiting fibrosis might be associated with up-regulation of KLF2-mRNA expression.

Objective To investigate the effect of ulinastatin (UTI) on the expression of brainderived neurotrophic factor ( BDNF ) and remyelination in mice with experimental autoimmune encephalomyelitis ( EAE).Methods Twenty-four C57BL/6 mice were randomly divided into UTI group (U),normal saline treated group (S) and normal control group (N,n = 8,respectively).Demyelinations in the spinal cord were observed by solochrome cyanin staining.The expression of BDNF,myelin basic protein (MBP),and 2',3 '-cyclic nucleotide 3'-phosphodiesterase (CNP) in brain tissue of each group were evaluated by Western blot.Results Average clinical scores in group U at the 12,13,14,22,23,31,33,34 and 35 days were 0,0.25,0.38,0.63,0.63,0.40,0.40,0.40 and 0.40 respectively.They were significantly lower than group S at the same time ( U= 16.00,15.00,14.50,7.50,0.00,14.50,14.50,12.00 and 14.50,all P ＜0.05).Solochrome cyanin staining showed that demyelination of spinal cord in group U was also significantly improved than group S.Expressions of BDNF ( 1.96 ± 0.29),MBP (2.67 ± 0.48 ) and CNP ( 1.75 ± 0.20) in group U were all significantly higher than group S ( There were 0.80 ± 0.15,1.36 ± 0.38 and 1.06 ± 0.18 respectively,all P ＜ 0.05).Conclusions UTI has protective effect on EAE.The possible mechanism is that it could promote remyelination,and protect oligodendrocytes and neurons in EAE model by increasing BDNF expression in brain.

In order to investigate the effect of deep brain stimulation on diseases such as epilepsy, we developed a closed-loop electrical stimulation system using LabVIEW virtual instrument environment and NI data acquisition card. The system was used to detect electrical signals of epileptic seizures automatically and to generate electrical stimuli. We designed a novel automatic detection algorithm of epileptic seizures by combining three features of field potentials: the amplitude, slope and coastline index. Experimental results of rat epileptic model in the hippocampal region showed that the system was able to detect epileptic seizures with an accuracy rate 91.3% and false rate 8.0%. Furthermore, the on-line high frequency electrical stimuli showed a suppression effect on seizures. In addition, the system was adaptive and flexible with multiple work modes, such as automatic and manual modes. Moreover, the simple time-domain algorithm of seizure detection guaranteed the real-time feature of the system and provided an easy-to-use equipment for the experiment researches of epilepsy control by electrical stimulation.
