Objective To compare the effects of 6MV and 10MV-X-ray intensity modulated radiotherapy (IMRT) on non-small-cell lung cancer (NSCLC) . Methods We randomly selected 20 patients with NSCLC, 6MV and 10MV X-ray were used respectively for each NSCLC patient with IMRT plan design, the ADAC Pinnacle 8.0f treatment planning system was applied to provide the convolution/iteration algorithm, for the same target IMRT plan design with two kinds of energy. By comparing the dose volume histogram (DVH),PTV parameter (Dmean, Dmin and Dmax), conformal index (CI) and homogeneity index (HI),we analyzed the metrology parameters . Results 6MV and 10MV radiation therapy plan DVH, PTV parameters,CI,HI and isodose line was similar,no statistically significant differences. But target dose homogeneity and the degree of target coverage in high dose of 6MV plan was better than that in 10MV plan. Endanger organs (OAR) such as normal lung tissue, heart, esophagus and spinal cord had basically same dose amount. Conclusion 6MV X-ray plan may be the better choice of radiotherapy on NSCLC.

[Objective] To investigate the effect of naringin at different doses on the neuropathie pain produced by lumbar 5 spinal nerve ligafion (L5 SNL). [Methods] Using the method of behavioral test, we tested the 50% paw withdrawal threshold before and after intragastrieal application of naringin in the rats with L5 SNL. [Results] Naringin at 30, 90, 100 mg/kg but not at 10 mg/kg increased the 50% paw withdrawal threshold of 1.5 SNL rats significantly. Single application of Naringin (at 30 or 90 mg/kg) inhibited mechanical allodynia for around 6 hours, and the inhibitory effect persisted for 4 days after the cessation of the drug when naringin (30 mg/kg, daily) was consecutively applied for 7 days. [Conclusion] Intragastrical of naringin could relieve the neuropathic pain produced by peripheral nerve injury.

OBJECTIVE:
To compare the effectiveness of sequential treatment for subjective and objective benign paroxysmal positional vertigo(BPPV).
METHOD:
The efficacy of sequential treatment for nineteen vertical semicircular canal S-BPPV patients(Group A) and forty-five vertical semicircular canal O-BPPV patients(Group B) who were admitted to our hospital between January 2014 and July 2015 was retrospectively analyzed and compared, treatment of five cases with horizontal semicircular canal S-BPPV was reported here as well.
RESULT:
The number of repositioning maneuver for Group A was 2 - 6 times (average: 4. 21±1. 18) while 2 - 3 times (average: 2. 29 ± 0. 46) for Group B. There was significant difference between the two groups(P<0. 01). The effective rate of initial treatment for Group A was 78. 9%(15/19) while 82. 2%(37/45)for Group B. After one weeks treatment, the effective rate for Group A changed to be 89. 5% (17/19)while 88. 9% (40/45) for Group B. Non-significant difference was found in the two groups neither in the initial nor one weeks treatment. On three months' follow-up, one in Group A and two in Group B relapsed, and they were cured after treated in the initial treatment. The recurrence for Group A was 5. 3%(1/19) while 4. 4%(2/45) for Group B and there was non-significant difference. The five cases with horizontal semicircular canal S-BPPV were completely free of disease after undergoing treatment.
CONCLUSION
The sequential treatment is effective for both vertical semicircular canal S-BPPV and vertical semicircular canal O-BPPV, but the former needs more repositioning maneuver times. The repositioning maneuver, combined with drug therapy and head-shake-in-supine-position method is recommended for horizontal semicircular canal S-BPPV.

Objective: The antitumor mechanism of Pleurotes sapidus on 4 kinds of tumor cell lines was studied. The active components of its ethanol extracts were studied. Methods:Using techniques of cell culture in vitro, phytochemical methods, FACS and RT-PCR, expressions of p53 and fas gene of four tumor cell lines treated with Pleurotas sapidu were analysed. Results:The apoptosis rates were remarkably increased after treated by ethanol extracts (0.1g/ml) and water extracts (0.1g/ml) for 12 h and 24 h respectively. The expression of P53 protein in the groups of ethanol and water extracts were significantly increased, and the gene expressions of p53 and fas were aslo highly up-regulated. Conclusion:The antitumor effect of Pleurotas sapidus on tumor cell lines in vitro is evident, and its mechanisms are probably associated with the regulation of apoptosis by inducing the gene expressions related to apoptosis.
