Objective:To explore the diagnosis and treatment of small intestine leiomyosarcoma. Methods:Ten patients with small intestine leiomyosarcoma in Changhai Hospital from 1993 to 2001 were retrospectively analyzed. Results:Radical resection was performed in 6 cases with the shortest survival time being over 1 year and the longest being 8.5 years (still in good health). One case received extirpation operation with the survival time being over 4 years.Partial resection was performed in 3 cases,and the 3 patients died 1,2,3 years after operation respectively.Conclusion:The small intestine leiomyosarcoma is rare and its diagnosis is difficult due to the lack of clinical feature. Final diagnosis should be based on pathology.The disease is not very sensitive to radiotherapy and chemotherapy,which makes surgical treatment the choice.

Objective To study on the neural mechanism of deficits in Chinese developmental dyslexia from the aspects of the phonological processing,orthographic skills,visual magnocellular function and cerebellum function.Methods Critical words in Chinese and English (e.g.dyslexia,reading development,Chinese,neural) and formula (e.g.Chinese and (reading development) and (neural or neuroimage or fMRI or ERP or brain area) related with the present topic were searched among the article abstracts in Chinese and foreign databases (e.g.CNKI,Pubmed,Sciencedirect) from July to December,2014.Results Fifty-two relevant articles were gained access to the database.Referring to the present topic,research on the neural mechanism of dyslexia with neuroimaging technique was reserved,while the studies in which the reading impairment of the participants was caused by acquired factors were eliminated.Finally,thirty-three valid articles were retained.Conclusion According to previous studies,although there might be similarities in cognitive deficits of dyslexia between alphabetic languages and Chinese,it was still found that the Chinese children with developmental dyslexia exhibited abnormal neural activities and impaired brain structures in areas associated with Chinese phonology (i.e.left middle frontal gyrus,which was different from the left inferior fiontal gyrus always related with phonological processing in alphabetic languages) and orthographic skills (right occipitotemporal areas which was responsible for the visuospatial processing),revealing language specificity of Chinese to some extent.However,some other studies reported the similarities in neural mechanisms of dyslexia across languages.Therefore,more studies were required to further examine the crosscultural mechanism of the neural activity regarding the developmental dyslexia.Meanwhile,researches on the aspects of general perception showed Chinese dyslexic individuals had deficits in visual magnocellular function,and cerebellum.Future studies were required to explore the relationship between the linguistic and non-linguistic deficits.

Objective: To compare the efficacy of moxibustion with different doses for knee osteoarthritis (KOA), and explore the correlation between moxibustion dose and clinical efficacy. Methods: Sixty-eight patients with KOA who met the inclusion criteria were randomly divided into a 20-minute moxibustion group and a 40-minute moxibustion group by the random number table method, with 34 cases in each group. Dubi (ST 35), Neixiyan (EX-LE 4) and Heding (EX-LE 2) were used for moxibustion in the two groups. Each treatment lasted 20 min or 40 min for each point in the 20-minute moxibustion group and 40-minute moxibustion group, separately; the treatment was given 3 times a week and lasted for 4 weeks. The visual analog scale (VAS), Western Ontario and McMaster University osteoarthritis index (WOMAC) and traditional Chinese medicine (TCM) symptom scores were evaluated before and after treatment to compare the efficacy between different moxibustion doses for KOA. Results: After treatment, the total effective rate was 87.5% in the 40-minute moxibustion group, versus 70.0% in the 20-minute moxibustion group, and the difference in the total effective rate between the two groups was statistically significant (P<0.05). After treatment, the VAS scores, the total WOMAC scores and the component scores of pain, stiffness and dysfunction, and the TCM symptom scores in both groups all changed significantly when compared with those before treatment (all P<0.05). After treatment, the between-group differences in the VAS score, the total WOMAC score and the component scores of pain and dysfunction, and the TCM symptom score were statistically significant (all P<0.05), while the difference in the stiffness score in WOMAC showed no statistical significance (P>0.05). Conclusion: Either 20-minute moxibustion or 40-minute moxibustion can relieve pain, improve stiffness, dysfunction, and TCM symptoms for KOA; and 40-minute moxibustion is better in relieving pain, improving dysfunction and TCM symptoms.

This study was aimed to explore the resource diversity and microbial inhibition activity of endophytic fungi from medicinal plant Plantago asiatica L. The endophytic fungi were isolated from the root, stem and leaf of the host by tissue inoculation culture and five plant pathogenic fungi and four bacteria strains used as indicating microbes to test microbial inhibition activity by agar plate antagonistic action and modified agar gel diffusion methods. The results indicated that thirteen fungal endophytic strains were isolated from the host. Most of them came from stem, then leaf, and root as the least in number. The isolated strains attribute to five genera, two fam-ilies, and two orders based on morphological characteristics. For the isolated strains, eleven of them were found to have some microbial inhibition activities against one or more indicating fungi, making up 84.6% of the total iso-lates. Six isolated strains had some antimicrobial activities against one or more indicating bacteria, amounting to 46.2% of the total isolates. Three isolated active strains, which are PAEFS001, PAEFS007 and PAEFS008, ex-hibited evident inhibition activities against five kinds of pathogenic fungi used in the trials respectively. The strain of PAEFS001 ascribed to Ozonium sp. Both strains of PAEFS007 and PAEFS008 ascribed to Aspergillus sp. One active strain of PAEFS003 showed evident antibacterial activities to Bacillus subtilis and Staphyloccus aureus, which belonged to Fusidium sp. The endophytic fungi from medicinal plant Plantago asiatica L. have evident an-timicrobial activities. Their inhibition activities against pathogenic fungi have relatively broad spectrum. And their inhibition activities to both Bacillus subtilis and Staphyloccus aureus as G+ are evident and have certain selectivi-ty. It is feasible to find new bioactive compounds associated with endophytic fungi from Plantago asiatica L. Fur-ther research and development of the endophyic fungi will be important for the integrated utilization of the host.

To illustrate the location of HSP-70 (heat\|shock protein\|70)correlative response in acute stage between middle and inner ear when mammalian middle ear infected by bacteria, and investigate the possibility to cause autoimmune inner ear injure by HSP-70 that induced by otitis media. An animal model of acute otitis media was established by inoculating Klebsiella pneumoniae (K.p) into middle ear of guinea pigs. Animals were sacrificed 1,3,5 and 7days after inoculation.Investigation of the locations of HSP-70 in middle ear mucosa and cochlea structures were detected by immunocytochemical technique .The results showed that light stain of HSP-70 existed in the superficial epithelium cells of normal mucosa and cochlea structures such as stria vascularis, spiral ligament and Corti′s organ.Heavy stain appeared in the same sites in the infected ears . No different positive sites was observed in all animals.Our findings suggested that HSP-70 were expressed in middle ear mucosa and inner ear structures during acute middle ear infective stage.The HSP-70 provide a material base for causing autoimmune inner ear injure during middle ear bacteria infection.

An HPLC method has been developed to determine polydatin in giant knotweed rhizome. In order to systematically validate the method, specificity, precision, linearity of reference solution and test solution, repeatability, reproducibility, accuracy, stability and robustness were measured. In the robustness test, a one-variable-at-a-time procedure was applied to evaluate the influence of slight variations in method factors, including the flow rate, the column temperature, the extraction time, and etc., on the assay result of polydatin. No significant differences were found when the process parameters changed during the experimental domain. And system suitability test limits were defined based on the robustness test. Results showed that the developed method was accurate, reproducible and robust.
