ObjectiveTo investigate advantage and disadvantage of different rehabilitation therapies used for cerebral palsy (CP) children complicated with epilepsy (EP).Methods140 CP children complicated with EP screened from 1402 CP cases, were analyzed for CP and EP types, MRI or CT, brain stem auditory evoked potentials (BAEP). All cases were treated with anti-epilepsy drugs (AEDs). Different rehabilitation therapies, including electrotherapeutic modalities, acupuncture, point injection, cerebroprotein hydrolysate injection, manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection were assessed.ResultsIn all 140 cases, a majority of EP types were myoclonic seizure and west syndrome, CP type was spasticity. Abnormality showed in MRI or CT (98%) and BAEP (90%). AEDs were effective for all 140 cases. Electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection could make EP severely, but manual therapy, functional training, Chinese herb braising therapy, cattle encephalon glycoside and ignotin injection had no adverse effects on EP cases.ConclusionThe principles of rehabilitation treatment for the CP children complicated with EP are taking AEDs early and in a long term, avoiding electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection, using manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection.

Objective: To develop the Chinese version of the Neuropsychiatric Inventory Questionnaire (NPI-Q) and evaluate its reliability and validity. Methods: Three investigators assessed 10 dementia cases together with the NPI-Q to evaluate the inter-rater reliability. Eighty-six dementia cases and 30 healthy controls were assessed with the Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD), the Brief Psychiatric Rating Scale (BPRS) and NPI-Q to evaluate the criterion validity. A subgroup of 30 dementia cases was tested with the NPI-Q again 24 h later to evaluate the test-retest reliability. Results: (1) Internal consistency. Cronbach's a coefficient of the severity subscale was 0.589, mean inter-item correlation coefficient of the severity subscale was 0.107. Cronbach's α coeffi-cient of the distress subscale was 0.612, and the mean inter-item correlation coefficient of the distress subscale was 0.114. (2) Inter-rater reliability. Intraclass correlation coefficient (ICC) of the severity subscale was 0.97, and ICC of the distress subscale was 0.94. (3) Test-retest reliability. The test-retest correlation coefficient of the severi-ty subscale was 0.89, and the test-retest correlation coefficient of the distress subscale was 0.86. (4) Criterion va-lidity. The severity subscale total score was correlated significantly with BEHAVE-AD (r=0.70, P <0.001) and BPRS(r=0.40, P<0.001) total score; the distress subscale total score was correlated significantly with the global ratings in part 2 of BEHAVE-AD (r=0.76, P<0.001) . (5) The severity subscale total score in demen-tia group was significantly higher than that in control group (median: 10 vs.1.5, P <0.001). The distress sub-scale total score in dementia group was significantly higher than that in control group (median: 10 vs 0; P< 0.001) . (6) Exploratory factor analysis identified 4 common factors, including psychosis, abnormal behavior,discontrol and affective symptoms, which explained 58.3% of total variance. All of the items loaded were between 0.596 and 0.803 on their conrresponding factor. Conclusion: The reliability and validity of the Chinese version of NPI-Q meet the psychometrics properties, and deserves to conduct further study in larger samples.

BACKGROUND:Thoracolumbar fracture becomes more in the clinic. The fixation manner of thoracolumbar fracture is controversial. Injured vertebra pedicle screw fixation or traditional cross-segment pedicle screw fixation are controversial and lack the support of evidence-based medicine. OBJECTIVE: To evaluate the outcomes of injured vertebra pedicle screw and cross-segment pedicle screw fixation for thoracolumbar fractures. METHODS: According to Cochrane system evaluation, the folowing databases were retrieved: National Library of Medicine database, China National Knowledge Infrastructure, Wanfang database and VIP database. Conference proceedings were searched by hand. The retrieval time ranged from 2005 to March 2015. Randomized controled trials were colected. Meta-analysis was performed by using Cochrane Colaboration Revman 4.2. RESULTS AND CONCLUSION: By screening, a total of 14 clinical controled trials were selected, including 956 patients. Meta-analysis results showed that postoperative Cobb angle was improved significantly in the vertebral pedicle screw group than in the cross-segment pedicle screw fixation group (OR=-2.72, 95%CI:-3.08--2.35,P < 0.01). Correction rate of the vertebral height was higher in the vertebral pedicle screw group than in the cross-segment pedicle screw fixation group (OR=7.45, 95%CI:6.94-7.97,P < 0.01). The failure rate was lower in the vertebral pedicle screw group than in the cross-segment pedicle screw fixation group (OR=0.12, 95%CI: 0.05- 0.27,P < 0.01). Results verify that postoperative Cobb angle improved significantly after the injured vertebrae pedicle screw and cross-segment pedicle screw fixation for thoracolumbar fractures. The height was obviously corrected and fewer complications were caused such as implant failure. The fixation effect was good.

Objective There are three categories of bioaerosol laser telemetry systems according to the light source configuration parameters:namely traditional lidar(light datection and ranging,laser radar), micro-pulse lidar and pseudo-random modulation(lidar).The system source parameters,which impact the degree of danger and detection sensitivity of the system, need to be optimized.Methods With reference to the USA laser product safety standards and by establishing the corresponding mathematical model of a lidar, the three categories of lidar source configuration were compared according to signal to noise ratio(SNR) and security before the repetition rate, pulse energy, divergence angle, distance and other dangerous impact factors were calculated.Results The results showed that to ensure eyesafety, the use of the pulse frequency should be set at 55 kHz for the highest SNR under the micro-pulse lidar excitation mode.Conclusion The eyesafety requirements impact the excitation of light source of a bioaerosol telemetry system.
