Object To establish the fingerprint spectrum of Coptis chinensis Franch. by HPCE. Methods The correlation relativity of retention time and peak area of each chromatographic peak in different batches of medicinal materials were explored respectively, and beberine was chosen as the reference to calculate the relative retention time and the ratio of peak area for each chromatographic peak. Results The correlation coefficients of relative retention time and the ratio of each chromatographic peak were all higher than 0.999 0 in different batches of medicinal materials. Conclusion The established fingerprint spectrum is stable and credible, and could be used as characteristic fingerprint spectrum for C. chinensis.

OBJECTIVETo explore a simple but novel method of strengthening gypsum material by cyanoacrylate infiltration. To evaluate the influence of cyanoacrylate on the mechanical properties of dental gypsum models.

METHODSGypsum specimens were polished to the dimension of 35 mmx4 mmx4 mm. Butyl-cyanoacrylate was diluted with chloroform at different concentrations, namely 20% and 30% cyanoacrylate. Gypsum specimens were infiltrated by diluting one component of cyanoacrylate at different concentrations for 8 h and then dried for analysis. The changes in elastic modulus, fracture toughness, compressive strength, biaxial strength, brinell hardness were measured. The data were analyzed using software OriginPro 8.

RESULTSThe viscosity measurements indicated that diluted cyanoacrylate were Newtonian fluids and the viscosity increased slightly within the 48 hours of preparation but still similar as water at room temperature, which could be used to infiltrating gypsum. The gypsum infiltrated with cyanoacrylate exhibited good physicochemical properties. The biaxial strength, fracture toughness, compressive strength and brinell hardness of the gypsum were improved by 39%, 30%, 63% and 18%, respectively.

CONCLUSIONCyanoacrylate can significantly improve the strength of gypsum model which indicates the potential clinical application.

Objective To report the clinical, myopathological and genetic features in myofibrillar myopathy (MFM) with numerous cytoplasmatic-spheroid bodies. Methods Ten patients in 5 successive generations began to present progressive proximal limbs weakness at 35 to 40 years old. Additionally, 4 cases manifested diarrhea and 6 cases accompanied with cardiorespiratory symptoms. An open biopsy was performed on the proband. In addition to histological, enzymhistochemical staining and ultrastructural examination, immunohistochemical staining with antibody against tau, desmin, ubiquitin, dysferlin, dystrophin-C', dystrophin-N' and dystrophin-R were done. All the exons of the MYOT, CRYAB, DESMIN, LDB3, LMNA, SEPNI gene and the FLNC exon 48 were analysed. Results Cytoplasmatic bodies and spheroid bodies were found in the fibers. The deposited material were positive for tau, desmin, ubiquitin, dysferlin and dystrophin-R, dystrophin-C'. Electron microscope showed granular dense Z-disc material in the inclusions which were surrounded by thin filament. There was no mutation in the above exons of the 7 candidate genes. Conclusions Myofibrillar myopathy involves multiple system impairment. Cytoplasmatic and spheroid bodies contain microtubule and membrane associated protein. The disease might be induced by some unknown genetic abnormities.

Objective To investigate the clinical characteristics of pontine infarction and the value of MRI in diagnosis of pontine infarction. Methods The cilinical feature and image manifestation of 65 cases with pontine infarction were analyzed retrospectively. Results Pontine infarction had complicated clinical presentation,classical syndrome was less,most presentation was similar to anterior circulation infarction. MRI especially DWI could found the infarction lesions earlier. Conclusion Pontine infarction and anterior circulation infarction have simlar presentations.MRI especially DWI could show the infarction lesions in supper-acute stage,could be helpful to diagnose.

Objectives: Patients with schizophrenia are more likely to die prematurely than the general population. They have a higher risk of cardiovascular related morbidity and mortality. Antipsychotic medications are also known to be associated with the prolongation of the rate-corrected QT (QTc) interval, which is linked to dangerous arrhythmias. The primary objective of our study is to investigate the practice of electrocardiogram (ECG) monitoring for patients with schizophrenia who were hospitalised. The secondary objective is to evaluate the prevalence of QTc prolongation in this group of patients. Methods: We included patients with schizophrenia who were discharged from the acute general adult psychiatric wards of the Institute of Mental Health in Singapore from 1 July 2014 to 21 July 2014. A retrospective analysis of the medical records was carried out to assess if they had received ECG during their hospitalisation. We also analysed their risk of developing QTc prolongation. Results: We had a sample size of 107 patients. There were 31 patients (29·0%) who received ECG during their hospitalisation. Of the 95 patients who had moderate-to-high risk of developing QTc prolongation, 29 of them received ECG. Of the 31 patients who received ECG, 10 of them (32·3%) had QTc prolongation. Conclusion: The ECG monitoring in the study patients was inadequate, and as a result, we were unable to evaluate the prevalence of prolonged QTc interval with confidence. We recommend performing baseline ECGs for these patients and conducting ECG teachings for clinicians who work in the psychiatric service settings.

OBJECTIVE: To evaluate the improvement of speech perception in Chinese-native cochlear implant (CI) children using frequency modulated system (FM system). METHOD: The mandarin speech perception (MSP) system was used to evaluate 11 cases with severe and profound hearing loss who were fitted cochlear implants. Listeners were asked to repeat MSP words presented in quiet and several different signal-to-noise ratio (SNR) conditions and percent correct word repetition was determined. Performance was evaluated under FM system and without FM (CI only). In addition, the listeners' subjective performance changes in the experiment were also observed. RESULT: (1) There was significant main effect of the device condition (with FM and no-FM) (F = 72.938, P < 0.01), a significant main effect of signal level (F = 230.715, P < 0.01), a significant interaction effect between the signal level and the device condition (F = 40.893, P < 0.01). (2) Listeners answered the question in a louder voice, showed more confidence, when using with FM system. CONCLUSION FM system could improve the speech reception in a complex environment for Chinese-native CI children.

Objective To determine the role of c-Jun N-terminal kinase (JNK) signaling in annulus fibrosus cells response to interleukin (IL)-1. Methods Rat annulus fibrosus cells cultured in monolayer were exposed to IL-1, with or without JNK inhibition by SP600125. RNA was isolated for Real-Time polymerase chain reaction (PCR) after 24 h stimulation. Results IL-1 upregulation of mRNA for inducible nitric oxide synthase (iNOS), IL-6, cyclooxygenase (Cox)-2, matrix metalloproteinase (MMP)-3, MMP-13 were blunted by JNK inhibition, while downregulation of collagenⅠand insulin-like growth factor (IGF)-1 were also reversed by JNK inhibition. Conclusion JNK signaling inhibition can be a therapeutic target for blocking intervertebral disc degeneration induced by IL-1.
