Objective Correctly identify Streptococcus pneumoniae resistant to optochin and other alpha hemolytic streptococcus susceptible to optochin.Methods Optochin susceptibility test, bile resolution test, latex agglutination test as well as some biochemical methods (VITEKCC4-GPI identifying cards,API-Strept identifying bar, VITEK TWO-GPC identifying cards) were applied.Results It was observed that 2 strains(0.3%)of Streptococcus pneumoniae out of 630 were resistant to optochin and 31strains of Streptococci, classfied as alpha hemolytic streptococci, susceptible to optochin, including 13 of S. mitis, 6 of S.oralis, 6 of S. twin, 3 of S. acidominimus, 2 of S.intermedius and 1 of S. constellatus. The inhibition zone of these alpha hemolytic streptococci susceptible sensitive to optochin was within the range of 14-17mm in diameter, in not 20 mm or more than 20 mm, compared with the inhibition zone of most strains of S.pneumoniae. Most of these alpha hemolytic streptococci (93.5%) susceptible to optochin showed highly resistance to benzoxazolecillin,to which most Streptococci (94%) showed sensitivity . Conclusion S.pneumoniae can be effectively identified by bile resolution test and latex agglutination test because of its high specificity with credible test results. API-Strept identifying bar and VITEK TWO-GPC identifying cards can be applied to identify S. pneumoniae resistant to optochin.

Objective: To explore the molecular biological mechanism of acupuncture in intervening visual deprivation.
Methods: Forty-eight 2-week old Wistar rats were randomly divided into a normal group, a model group, and 6 acupuncture groups (group C1: acupuncture at the unaffected side in early stage; group C2: acupuncture at the affected side in early stage; group D1: acupuncture at the unaffected side in mid-stage; group D2: acupuncture at the affected side in mid-stage; group E1: acupuncture at the unaffected side in late stage; group E2: acupuncture at the affected side in late stage) by the random number table, 6 rats in each group. Rats in the normal group didn’t receive any interventions. The rat model of deprivation amblyopia was established by unilateral eyelid suture in the model group and each acupuncture group. After successful modeling, rats in model group didn’t receive any treatments; rats in the acupuncture groups received acupuncture intervention which began respectively on the 3rd, 12th and 21st day after modeling. Pattern visual evoked potential (P-VEP) and N-methy D-aspartatreceptor-1 (NMDAR1) mRNA expression in visual cortex area 17 were detected at the end of acupuncture intervention in each group.
Results: After the intervention, the P-VEP waveform was significantly changed, with a significantly delayed P100 value (P<0.01) and significantly decreased amplitude of N45-P100 in the model group versus the normal group (P<0.01); the P-VEP waveform was significantly improved, with obviously earlier P100 (P<0.01) and increased amplitude of N45-P100 (P<0.05) in each acupuncture group versus the model group. The improvement effect of acupuncture on the P-VEP waveform in group C1 and C2 was more significant than that in group D1, D2, E1 and E2. The expression of NMDAR1 mRNA of the rat visual cortex area 17 in the model group was significantly lower than that in the normal group (P<0.01); and the expression of NMDAR1 mRNA in the visual cortex area 17 of each acupuncture group was significantly higher than that in the model group (P<0.05); the effect of acupuncture on NMDAR1 mRNA expression in group C1 and C2 was more significant than that in group D1, D2, E1 and E2; and the effect of acupuncture on NMDAR1 mRNA expression was better in group C2 than in group C1 (P<0.05); there was no significant difference in the expression of NMDAR1 mRNA between group D1 and D2, neither between E1 and E2 (P>0.05).
Conclusion: P-VEP waveform is abnormal and NMDAR1 mRNA expression in visual cortex area 17 is decreased in rats with monocularly-deprived amblyopia. Acupuncture in the sensitive period can significantly regulate the abnormal P-VEP waveform and the down-regulate the NMDAR1 mRNA expression of the visual cortex of rats with monocularly-deprived amblyopia. Early treatment in the sensitive period should be the key to obtaining the curative effect.

Objective To analyze the evaluation value of ABCD2 combined with carotid ultrasound on the prediction of cerebral infarction after transient ischemic attack. Methods The clinical data of 133 patients with TIA admitted from July 2014 to December 2015 were analyzed. We score patients according to the standard of ABCD2 score and carotid ultrasound. The incidence of cerebral infarction within 7 days was observed. Results In the 133 TIA patients 35(26.3%) progressed to cerebral infarction. The 7-day incidence of cerebral infarction was 7.1% in patients with an ABCD2 score of low risk (0-3), 25% with a score of moderate risk(4-5), and 40% with a score of high risk(6-7). The difference of the incidence of cerebral infarction was significant between the low and moderate risk stratification (P < 0.05). The 7-day incidence of cerebral infarction was 39.5% in patients with carotid plaque and 75.0% in patients with carotid stenosis , both higher than the control group (P < 0.05). In the ABCD2 score ≥4 group, the incidence of cerebral infarction in the patients with abnormal carotid ultrasound was 38.4% ,significantly higher than the patients with normal carotid ultrasound (P < 0.05). Conclusions The ABCD2 score is effective to predict short-term risk of cerebral infarction in the patients with TIA. Combination with carotid ultrasound can improve the predictive accuracy of 7- day risk of cerebral infarction after TIA.

Brain injury is one of the most serious diseases in neonatal period,which can cause cerebral palsy,motor development delay,cognitive dysfunction and learning difficulties and other sequelae,and severely affects the health development and quality of life of the newborn.Neonatal brain injury (NBI) is a wide range of diseases caused by a variety of causes,its clinical manifestations lack specificity,clinically,it is difficult to judge the severity,duration and the time of prenatal injury,and it has been paid much attention to by scientific researchers and clinicians.At present,imaging method is a major means of NBI diagnosis,but imaging examination is usually a lag and limitations.Levels of humoral biomarkers change early after brain injury,and early brain injury can be predicted by detecting their changes.In recent years,a variety of sensitive brain damage biomarkers have been detected in various body fluids of newborns,mainly including neuron-specific enolase (NSE),ubiquitin carboxyl hydrolase L1 (UCH L1),S100B protein,tau protein,myelin basic protein (MBP),glial fibrillary acidic protein (GFAP) and activin A and so on.the application and research progress of these commonly used biomarkers in NBI are reviewed in this paper.
