Objective To explore the features of clinical manifestations and electrophysiology of spinal muscular atrophy(SMA) in children.Methods The clinical features and laboratory data were analyzed in 32 children with SMA,electromyography tests were carried out in 28 patients and the muscle biopsy were performed in 24 cases.Results The 32 cases were subdivided into 3 clinical groups,15 cases were SMAⅠ,12 cases were SMAⅡ,5 cases were SMAⅢ.They were all characterized by progressive muscle weakness associated with hyptonia and atrophy.The clinical distinction between SMAⅠto SMAⅢ reflected different age of onset and disease severity.All cases of SMAⅠhad symptoms of respiratory disability,only 1 case of SMAⅡ had paradoxical breathing and none of SMAⅢ had similarly symptoms.Electromyographic studies showed a pattern of denervation with no sensory involvement.The rate of spontaneous potential was 87%,with gentle strain,the duration of motor unit was extended(30%-150%) and the amplitude of it was increased(90%-450%),the motor nerve conduction velocity was reduced slightly in 28% patients.The muscle biopsy provided evidence of skeletal muscle denervation with groups of atrophy.Conclusions The clinical features,the changes of electromyography and the muscle biopsy are valuable for diagnosis of SMA.Respiratory management will prolong survival and improve the quality of life for these patients.

The epidermal growth factor receptor (EGFR) is overexpressed in many epithelial cancers,and is commonly caused by EGFR gene amplification and gene mutations. The most frequently occurring variant,the type III mutation (EGFRvIII) ,is characterized by an inframe deletion of exons 2-7 of the coding sequence. It is expressed only in tumors and not found in normal tissues, and therefore represents an attractive therapeutic target. The tumor therapy methods targeted for EGFRvIII include immu-notherapy, ribozyme, RNA interference, etc.

Pain is all lumbocrural pain cases very common clinical symptoms,but the etiology, pathology, site (range or area), intensity, nature, evolution situation and influence factors of pain usually has some certain characteristics and rules, these differences particularly are regarded as the primary and important basis or clue for the clinical diagnosis and differential diagnosis of related diseases. In addition, according to these differences can determine the individual diagnosis of lumbar intervertebral disc herniation as well, including typical and atypical, simple and compound, the general and special cases, these be- come the basis to determine the individualized therapeutic schedule of this disese.

Pain is common clinical symptoms of lumbocrural, but the etiology, pathology, sites (range or area), intensity, nature, evolution situation and influence factors of pain has some certain characteristics and rules. These differences particularly were regarded as the primary and important basis or clues for the clinical diagnosis and differential diagnosis of related diseases. A series of exclusive diagnosis for similar symptoms is premise of diagnosis of lumbar intervertebral disc protrusion. Ideas and methods of differential diagnosis of lumbar intervertebral disc herniation can help the diagnosis and identification.

Lumbar intervertebral disc herniation clinical symptoms and signs are very complicated, lumbocrural pain is the most characteristic clinical symptoms,and show the site (range or area), intensity, nature, evolution, influence factors and adjoint symptoms and so on has certain characteristics and rules. Among them, the dermatomal pain, kinesthetic dysesthesia, dynamic changing pain and lesions segment vertebral side deep tenderness are the most impotent characteristics and rules of pain, therefore, can be regarded as the main basis of clinical diagnosis of the disease, and also the core content of this article.

Objective To understand the molecular epidemiology characteristics and its drug resistance of methicillin-resistant Staphylococcus aureus (MRSA) in the urban area of Jilin and to provide important basis for guiding the clinical medication and prevention of the MRSA infection. Methods One hundred and three strains of MRSA from July 2013 to July 2014 in the urban area of Jilin were selected. The polymerase chain reaction (PCR) technology and multiple polymerase chain reaction were used to detect mecA gene and Staphylococcus chromosomal cassette mec typing (SCCmec) genotype of MRSA. The drug sensitivity test for 13 kinds of clinical common antibacterial drugs were detected by using the K-B method. And the source of the strains were analyzed. Results The results of SCCmec genotype of MRSA showed that SCCmecⅢtype were 62 strains, accounting for 60.2%;SCCmecⅡtype were 39 strains, accounting for 37.9%; failing to parting were 2 strains,accounting for 1.9%. Drug susceptibility test results showed that all of 103 MRSA strains were resistant to cefoxitin, cefazolin, penicillin and benzene, and drug resistance rate was 100.0%. The resistant rate to erythromycin, levofloxacin, ciprofloxacin, tetracycline, gentamicin and rifampin were 96.1%, 93.2%, 95.1%, 91.3%, 90.3%and 55.3%receptively;the resistant rate to sulfamethoxazolewas was only 1.9%;and the resistant strains to vancomycin and teicoplanin were not detected. The top three department of the distribution of the strains source were department of neurosurgery (31.1%), ICU (19.4%) and burn plastic surgery (17.5%). Conclusions The SCCmecⅢtype is the main MRSA epidemic strains, and SCCmec type II is a minor epidemic strainin the urban area of Jilin. The antibiotic resistance of MRSA is a serious problem with multiple drug resistance, but MRSA is sensitive to vancomycin and teicoplanin.

To compare the anxiolytic effects of reduced metabolite of progesterone and benzodiazepine.Methods The effects of allopregnanolone and diazepam on spontaneous locomotor activity and on exploration in the elevated plus-maze were studied in C57 mice 20 min after vehicle or drug intraperitoneal administration.Results Allopregnanolone (0.1 mg.kg-1,ip) elicited marked anxiolytic effects in terms of significantly reducing the latency to enter the open arm from (31.30±8.39)s to (8.80±6.00)s,(P<0.001),and significantly increasing both the number of open arm entries from 1.20 ± 0.42 to 4.80 ±1.75,(P<0.001) and the proportion of total time spent on the open arm from 7.13% to 32.50%,(P<0.001).Meanwhile,the diazepam (0.25 mg·kg-1) produced a lower anxiolytic effect comparing to that of the allopregnanolone.Analysis of spontaneous locomotor activity showed while 0.5 mg·kg-1 of diazepam decreased the locomotor activity (P<0.01),neither 0.1 mg·kg-1 of allopregnanolone nor 0.25 mg·kg-1 of diazepam affect the locomotor activity score.Conclusion Together,these results provide evidence for differential behavioral actions of the neurosteroids and benzodiazepines.Since the allopregnanolone produce a selective anxiolytic effect without affecting the spontaneous locomotor activity,the allopregnanolone may be a better alternative for diazepam in treating anxiety.
