The effect of Ultraviolet (UV) rays on the activity of parasporal crystal of Bacillus thuringiensis, var. Kurstaki HD-1 strain was studied by SEM, SDS-PAGE, bioassay and other methods. It was found that the morphology and surface structure of PC were damaged ,and its solubility in alkaline solution or silkworm gut juice was decreased after being irradiated by UV, the solubility was lost completely after a long time irradiation over 5 hours, so the processed PC could not be degraded into protoxin with insecticidal activity and was denatured.

Neuropathy pain, or neuropathic pain (NP), which pathogenesis is complex and is lack of effective treatment, is one of common chronic pain in clinic. Studies of traditional Chinese medicine (TCM) in treating NP were increased in recent years. In the review, studies of treatments of TCM compound and monomer in NP during last decade were collected and analyzed to find out possible mechanisms, and some existing problems.

Medical Picture Archiving & Communication System (PACS) and Radiology Information System (RIS) are the two embranchments of medical informatics developing most rapidly. The correlative legal issues of medical PACS and RIS should be paid attention to.

Objective To study the variations of the contents of trace elements in first section of tap water stagnating in pipe over night. Methods The first and middle sections of tap water stagnating in galvanized iron pipe for water supply over night for about 10 hours flowing through an iron tap and a chromed tap were sampled and determined for the contents of copper, manganese, iron and zinc by atomic spectrophotometry. The relationship between the variations of contents of four elements and the flow capacity was analyzed also. Results The contents of copper and manganese in the first section and middle section of tap water stagnating in pipe over night accorded with the sanitary standard for drinking water (SSDW), and revealed no significant differences between the first and middle section of tap water. The contents of iron in first section of tap water flowing through an iron tap and the contents of zinc in first section of tap water flowing through a chromed tap both exceeded the SSDW and revealed higher levels respectively compared with those in the related middle section of tap water. The levels of iron and zinc negatively correlated with the flow capacity (r Zn=-0.938,P

0.05) respectively. Conclusion: The SY 1 silicon elastomer have suitable physical, mechanical and anti ozone aging properties.

Objective: To observe the effect of ATENS on distance and near vision and stereopsis in amblyopic children patients.Methods: 80 eyes from 70 patients with amblyopia were randomly divided into two groups: the group of ATENS and the group of western medicine.The difference of distance,near vision and stereopsis before and after treatment and between two groups after treatment were observed.Results: Distance and near vision improved and stereopsis diminished significantly after treatment in the TENS group and the western medicine group(P0.05).The curative effect and improving stereopsis in the western medicine group were better than that in the TENS group(P

Objective:To study the effects of ozone aging on the color stability of the SY-1 silicone elastomer. Methods :40 SY-1 silicone elastomer samples were prepared and grouped into 4 with 10 in each group. The samples in each group were painted with gouache color, oil pigment and inorganic salt respectively, one group was used as the control. Then the samples were treated with ?=10 -4 % ozone at 10～16 mm/s for 72 h. The color of the samples were measured by 1976 CIE L *a *b * standards of chromatic aberration before and after ozone treatment. The chromatic aberration was expressed as △E=〔△L *)2+(△a *)2+(△b *)2〕 1/2. Results :After 72 hours of ozone aging, △E of the samples in the groups of control, gouache color, oil pigment and inorganic salt was 0.55?0.11, 3.55 ? 0.09, 1.40 ? 0.11 and 1.57 ? 0.07 respectively ;Conclusion:Under the ozone aging condition, the SY-1 silicone elastomers stained with oil pigment and inorganic salt may have better color stability than that with gouache color.

ObjectiveTo explore the relationship between plasma homocysteine (Hcy), polymorphism in 5,10-methylenetetrahydrofolate reductase (MTHFR) and cystathionine-β-synthase (CBS), and cerebral thrombosis.Methods87 subjects with first-ever acute cerebral thrombosis and 80 controls were studied. The plasma Hcy levels were measured using high-performance liquid chromatography-fluorescence detection (HPLC-FD). The polymorphism in MTHFR was determined by a polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion and that in CBS was determined by amplification refractory mutation system (ARMS).ResultsThe fast plasma Hcy level in the patient group was (15.28±4.33)μmol/L significantly higher than that ( 11.32 ±3.86)μmol/L in the control group (P<0.001). Different genotype had different influence on the plasma Hcy levels. There were no differences in genotype frequencies or allele frequencies between the patient group and control group (P>0.05).ConclusionCommon mutations in MTHFR, CBS G919A and CBS T833C lead to hyperhomocysteinemia. Hyperhomocysteinemia, but not common mutations in MTHFR and CBS is associated with the increased incidence of cerebral thrombosis.

Objective ERP research has always been the hot spot of the n~ve electrophysiology research.A gTowing body of research suggests that ERP can effectively reflect the cognitive function in patients with depression,evaluate the risk of suicide.This paper reviews the ERP related components with depression and related research.On the basis of the application of ERP in the depression research discusses limitations and prospects on the later development.Methods The articles were retrievaled from databases,such as P UBMED,Foreign medical information resources retrieval platform,CNKI,Wanfang database,ect,from 2013-06 to 2015-01.Index strategy TI:TI:[depression OR affective disorder] AND [suicide OR suicidal] All field:event related potential.Reading and narrowing the scope of the articles,we should understand the experimental design,such as Sample company have suicidal ideation and (or) behavior of patients with depression.Potential induced way,ERP related component detection method,etc.The articles included 43 in English and 15 in Chinese.Read the full text and retain nearly five years about depression and related literature.Results Eventually,the article includes 34 articles and 3 of in Chinese.Conclusion Associated with suicidal ideation and (or) behavior of the existing cognitive dysfunction in patients with depression,ERP related components such as:abnormal P300 and CNV,MMN.N400 have not found abnormal.This article only from the Angle of depression and related research are reviewed in this paper the characteristics of ERP,ERP of other mental illnesses among related research,and to be perfect in the future.

To promote acupuncture practice, the general situation of acupuncture in treating leucopenia between 1949-2004 were analyzed on the basis of Chinese Modern Acupuncture Database. From 1981, references of acupuncture treating leucopenia increased annually and steadily.In clinic, hydroacupuncture, needling, and moxibustion are widely used, and the selected acupoints are those of Bladder Meridian of Foot Taiyang and Governor Vessel. Acupuncture-moxibustion have a good therapeutic effects on leucopenia.
