ObjectiveTo report clinical, pathological and molecular genetic features in a Chinese family with hereditary motor and sensory neuropathy type 6. MethodsThe index case is a 15 years old boy.He developed progressive distal limb weakness at the age of 5.The disease deteriorated slowly,accompanied with contracture of achilles' tendon. At the age of 11 years old he suffered from decrease of visual acuity. At the age of 12, he found the muscular atrophy of both hands without sensory disturbances.Visual evoked potential revealed prolonged latency of bilateral P100. Ophthalmological examination showed bilateral optic atrophy. His mother had the similar symptoms at the age of 7 and reduced visual acuity at the age of 10. Nerve conduction velocity revealed in both pat1ents no compound motor and sensory nerve action potentials in most nerves or slightly reduced nerve conduction velocities with severely reduced amplitudes of the compound motor and sensory nerve action potentials. Sural nerve biopsy was performed on the proband.The sequence of MFN2 gene was analyzed in DNA from the index, his mother and 100 healthy controls.ResultsSural nerve biopsy revealed severe loss of myelinated fibers with few regenerating clusters.Ultrapathological examination showed a few of atypical bulbs of myelinated fibers, occasionally regenerating clusters, mitochondrial swelling and aggregation in a few of axons. A new mutation of W740R mutation in MFN2 gene has been identified in the index case, her mother, but not in 50 healthy controls. Conclusions A novel MFN2 gene mutation result in hereditary motor and sensory neuropathy type 6.Mild visual loss appeares after the lesion of spinal nerves. Demyelination of peripheral nerve appears in the disease.

AIM and METHODS: To observe the effects of glucose-free and Mg 2+ -free in the extracellular fluid on the changes of [Ca 2+ ] i in the cerebro-cortical neurons damaged by 1 mmol/L glutamate using laser confocal scanning microscope. RESULTS: Both frequency and amplitude of neuronal calcium oscillation induced by glutamate were lowered in glucose-free and Mg 2+ -free buffers. The basic [Ca 2+ ] i concentration was lowered in the former case , but it was elevated in the latter case. CONCLUSION: Mg 2+ -free aggravates [Ca 2+ ] i overload induced by 1 mmol/L glutamate ,under certain conditions the glucose-free might resist damage role of glutamate and Mg 2+ -free.

[Objective] To explore how to deal with the paternity test of complex adoption cases. [Method] Samples from 13 families, in which adoptive parents were suspected related to biological parents, were genotyped using "Identifder + Sinofder + Powerplex 16" combined system (D8S1179, D21S11, D7S820, CSFIPO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, VWA, TPOX, D18S51, D5S818, FGA, D6S1043, D12S391, PentaD, PentaE) followed by further statistical analysis. [Result] Among all 13 cases, 2 were completely accordance with the Mendel law, PI > 10 000. There found more than 3 inconsistent loci in 8 cases. And found 1~2 inconsistent loci in 3 cases, needed to test more STR loci until PI≥10 000. The half sibling index (HSI) was also calculated with ITO method. The adoptive parents of 2 cases were not excluded from a full sibling with biological parents. In addition, Y-STR loci were tested for 4 cases (father/son). Two adoptive fathers of them were not excluded from the paternal relationship with biological fathers. [Conclusion] The most (76.9%) of all (13) complex adoptive cases of paternity test could be drawn a definite conclusion with combined system of "Identifder + Sinefiler + Powerplexl6". Minority (23.1%) of them was not definite yet and needed testing more STIR loci. Meanwhile, we suggested adding Y-STR tests and providing HSI for reference.

Objective To analyze the effects and experience of ideological and political education through inquiring students' satisfaction on it,and to strengthen innovation and efficiency. Methods Five hundred and fifty university students were chosen by random.Through anonymous questionnaires,information on attention and satisfaction of ideological and political education about educate by all staff,campus culture,psychological status,and extracurricular activities were acquired.Results More than 56% of the students thought who impressed them most were the professional teachers;and 75.64% of them would ask friends for help when they were facing difficulties.And 44.91% considered study as the main resource of pressure,although the other 39.09% chose the career perspective.Then,57.45% were willing to take part in the meaningful activities after class,though the study was tough.And 45.45% hoped it would be a great progress on extracurricular activities;74% would take part in entertainment,and on the other hand 68.55% chose volunteer;and 87.72% interested in learning psychological knowledge. Conclusion It is important to strengthen and develop ideological and political education among students in the university.And attention should be paid to the innovation and efficiency of the education.

AIM: To establish an experimental model of high intraocular pressure in mice by laser photocoagulation and to prepare for future research.
METHODS: Experimental model of high intraocular pressure was induced unilaterally in 44 C57BL/6 mice. The fellow eye served as a control. TONO-PEN AVIA Tonomter was used to measure intraocular pressure (IOP) to guarantee IOP value at 1, 2, 4, 8wk. Slit-lamp biomicroscopy was performed throughout the period and the structural changes were assessed histologically. And then, their eyes were enucleated, postfixed, cryoprotected, and embedded in optimal cutting temperature medium. After hematoxylin and eosin stain ( HE stain ) , cryosections of the retina were observed under light microscope. TdT-mediated biotin-dUTP nick end labeling ( TUNEL ) was performed on the retinal sections to determine apoptosis rate.
RESULTS: IOP of laser-treated eyes was significantly higher than that of control eyes from 1-8wk (P<0. 05). The highest IOP was 31mmHg, but only one eye. The IOP was mainly around 20mmHg. In laser-treated eyes, the angle of anterior chamber were narrow. Number of cells in the inner nuclear layer and retial gangllion cell layer was slightly lower than that in control eyes at 2wk, but by 4 and 8wk the number of cells was significantly lower than that in the control contralateral eyes.
CONCLUSION: The laser photocoagulation of limbus causes chronic elevation of IOP and this method may be a promising experimental model for the investigation of biological mechanisms of glaucomatous retinal ganglion cell damage.

This study aimed to analyze the etiology of the encephalitis outbreak in Longyan, Fujian Province, China in 2010, in order to provide valuable information for this prevention and control of this disease. Pathogens were confirmed from cerebrospinal fluid samples with fluorescent RT-PCR, virus isolation (RD cells), and neutralization tests. Then, the VP1 fragments or whole genome nucleotide sequences were determined for four virus strains using PCR. Homology was assessed using the MegAlign software, and a phylogenetic evolutionary tree was drawn using Mega 4.0 software. The results confirmed that the etiology of the outbreak was the ECHO6 intestinal virus, and the nucleotide sequence of the VP1 segment indicated that the C2 subtype was responsible. The genome sequence consisted of 7407 nucleotides, and resembled the genome of other ECHO and CoxB viruses with homology levels of 78.5%-87.3%. The encephalitis outbreak in Longyan in 2010 was caused by the ECHO6 C2 subtype intestinal virus, and its complete genome sequence length is similar to the standard strain (U16283) with a sequence homology of 80.4%.

The solubility parameter determination of astrageloside from Buyang Huanwu decoction with inverse gas chromatography (IGC) method evaluation was investigated in this paper. Di-n-octyl phthalate Kwai alternative sample was used to carry out methodological study. The accuracy of the measured correlation coefficient was 0.992 1. Experimental precision measured by IGC experiments showed that the results were accurate and reliable. The sample was uniformly coated on the surface of an inert carrier and N2 gas was carrier gas, a variety of polar solvents such as isopropanol, toluene, acetone, chloroform, cyclohexane as probes. TCD detector temperature was 150 degrees C, gas room temperature was 120 degrees C. Similar headspace method was used whichever over 1 μL gas into the GC measurement, Retention time t(R), t(0) and all the parameters of air and probes molecules within the column were tested. Astragaloside solubility parameter was (21.02 ± 2.4) [J x cm(-3)] ½, literature value was 19.24 [J x cm(-3)] ½, and relevant coefficient was 0.984 5. IGC method is effective and accurate to measure ingredients solubility parameter.
