Twelve populations of Inula lineariifolia were used as materials to measure morphological characteristics, photosynthetic parameters and chemical constituents. It aims to provide a theoretical basis for germplasm resources evaluation. The results showed that I. lineariifolia had relatively rich morphological diversity, there were significant differences of morphological characteristics, photosynthetic parameters and chemical constituents among populations. There was positive correlation on morphological characteristics and P(n). Twelve populations were divided into three-type. The three populations of Xuyi, Mingguang and Fengyang were of narrower-longer leaf, bigger biomass,better photosynthetic and higher chemical constituents. Then they were classified for a similar group. It proved that the three populations were more suitable for cultivation and promotion.

Aim To investgate the mechnism through which ginkgolides affect learning and memory capabilities of the Alzheimers disease-like rats. Methods Okadaic acid(OA)was injected into the CA1 region of the rat hippocampus and the rats were gavaged with ginkgolides. The learning and memory abilities of the rats were assessed through Morris water maze behavioral test, and the expressions of nicotinic acetylcholine receptors and ChAT were observed by Western blotting and immunohistochemistry, respectively.Results Compared with the control rats, the capabilities of learning and memory were lowered significantly(P

AIMTo study a new way to prepare high-dosage paclitaxel entrapped magnetic targeted nanoparticles and evaluate its quality.

METHODSFe3O4 nanoparticles are prepared by co-depositing, at the same time ultrasonic is used to decrease soft agglomerate of nanoparticles and increase disperse level of it. The property of nanoparticles surface is improved to make the integrating of liposome and nanoparticle to be tighter. At last, paclitaxel entrapped magnetic solid liposome nanoparticles have been prepared by microemulsion-curing under low-temperature. The loading efficiency and encapsulating rate were determined by reverse-phase high-perfomance chromatography.

RESULTSThe nanoparticles have spherical shape. Diameter of nanoparticle ranged from 150 nm to 170 nm. 98.29% of the drug is entrapped in the particle.

CONCLUSIONMagnetic susceptibility of nanoparticles is high, and the nanoparticles meet with the demand of targeted delivery system.

Objective To evaluate the changes of nerve conduction velocity in degenerative rabbit sciatic nerve authograft induced by 60Co irradiation after orthotopic replantation. Methods A 30-mm-long segment was severed from normal adult rabbit sciatic nerve and exposed to 60Co irradiation at the dose of 350 Cry to induce neural degeneration. The nerve segment was then replanted orthotopicaily, and the nerve conduction velocity was determined using electrophysiological test at 4, 6 and 8 months after the replantation. Results At 6, 8 months after the replantation, the nerve conduction velocity in the degenerative nerve autograft showed no significant difference from that in normal sciatic nerve (P>0.05). But at 4 months after the replantation, the nerve conduction velocity in the autograft was significantly lower than the normal velocity (P<0.05). Conclusion The nerve conduction velocity can be obtained by replantation of a long (3 mm) degenerative nerve segment due to 60Co irradiation.

OBJECTIVETo explore and identify the non-coding RNAs related to tumors.

METHODSWe used RT-PCR and Northern blot to analyze non-coding RNAs in tumor tissues and cell lines.

RESULTSTwo predicted non-coding RNAs were confirmed to be expressed in cancer tissues and cell lines by RT-PCR and DNA sequencing. We detected the expression of two non-coding RNA transcripts by Northern blot. The length of NC28 was about 1800 nt, and that of NC119 was about 1200nt.

CONCLUSIONSNC28 and NC119 have a tumor-associated expression pattern. The non-coding RNAs may play a role in the development of tumors.

OBJECTIVETo discuss the treatment of the windblow hand deformity.

METHODSWe treat 18 patients with operations step by step. First phase: to improve the thumb function; Second phase: shift the flexor digitorum superficialis of the middle and little finger to improve the ulnar drift of the digits; Third phase : to solve the flection deformity of the palm and digits.

RESULTSWe follow the patients for 6 - 72 months, only lost 3.11 of 15 patients have the thumb function recovered. 9 patients had their ulnar drift of the digits corrected, 2 patients partly corrected, 4 have relapse. 5 among the 15 patients were offered second operation, to have the ulnar arthrosis bursa contracted, using abduction splint, after rehabilitation 4 patients have the deformity corrected, 1 has partly corrected.

CONCLUSIONSOperation step by step is better for the complex windblow hand deformity, solve one major problem each time,and systemic rehabilitation therapy is needed for satisfied curative effect.
