Objective To investigate the manifestation and the prevention means of video display terminal (VDT) visual fatigue in old people. Methods Conventional eye inspection were performed for 45 patients, including optical muscle movement, position of eye, confluence function and presbyopia. Results We found that the average difference between middle distance correcting lens and 33 cm reading distance from presbyopia correcting lens was about 0.52 DS( P

Qi-Gui-Yin (QGY) compound, which composes of five herbal medicines of Astragalus membranaceus (Fisch.) Bge., Angelica sinensis (Oliv.) Diels, Lonicera japonica Thunb., Artemisia annua L., and Polygonum cuspidatum Sieb.et Zucc., which is able to treat antibiotic-resistant bacteria with antibiotics, and also to delay or even reverse the bacterial resistance producing. However, QGY compound is a complex mixture. And it is very difficult to elaborate its material foundation. Therefore, chemical constituents in five herbal medicines were summarized through searching of the related literatures. And then, 170 kinds of bioactive ingredients were classi-fied in order to provide evidences for the study on chemical constituent of QGY compound and identify its mate-rial foundation of delaying drug resistance .

OBJECTIVETo investigate and analyses feasibility and therapeutic effect of pedicle of vertebral arch drilling in the treatment of old vertebrae compression fracture patients suffering back pain.

METHODSFrom May 2004 to December 2011, 19 patients with back pain caused of old vertebrae compression fracture were treated by vertebral body decompression with drilling. There were 13 males and 6 females with with an average age of 61 years old ranging from 44 to 78 years. The course of disease was 3 months to 8 years (means 2.5 years). Among them,6 cases were chest-back pain and 13 were lumbodorsal pain. The thoracic vertebrae fracture involved in 9 segments, lumbar vertebrae fracture involved in 18 segments, vertebral height lose

RESULTSNineteen patients were followed up from 6 months to 3 years. The symtoms were not recurrened. The VAS score was 5.7+/-0.3 preoperative and 2.3+/-0.2 postoperative. The pain relieved obviously in 4 patients and mainly in 5 patients at 24 hours after operation, and the pain relieved obviously in 10 patients and mainly in 9 patients at 48 hours after operation.

CONCLUSIONVertebral drill decompression is an effective method for the treatment of old osteoporotic compression fractures with minimally invasive and low complication.

Objective: To investigate the antihypertensive time-effect and dose-effect features of Sancao jiangya decoction(SCD).Methods: The blood pressure of spontaneously hypertensive rats at different time points were measured after treatment with Sancao jiangya decoction of low,middle,high concentration by tailartery blood pressure measurement for conscious rats.Results: The blood pressure was decreased at 2 hours after drug taken,there were significant dose-effect relationship between the antihypertensive effect and the low,middle,high dose.At 4h after drug taken,the high,middle dose had dose-effect correlation,but the low-dose had no antihypertensive effect.Further research on the middledose shows that the blood pressure reduced at 1h after drug taken,and the stable antihypertensive effect was keeping during 1-4h,the blood pressure began to rise at 6h,and got back to the level before drug taken at 8h.Conclusion: To choose the Middle-dose(10.4g crude drug/kg body weight) and 2h after drug taken is appropriate for SCD's use.This result laid a substantial foundation for further research on effects evaluation and mechanism of antihypertensive medicine.

Aim To study the effect of genistein on apoptosis in human breast cancer MDA-MB-231 cells and the underlying mechanisms. Methods MTT as-say was used to observe the inhibitory rate on human breast cancer MDA-MB-231 cells treated with genistein. Colony assay was used to determine the cell colony formation rate on human breast cancer MDA-MB-231 cells treated with genistein. Western blot was used to detect the expression of Bcl-2, Bax, caspase-3,NF-κB, ERK, p-ERK, JNK and p-JNK in human breast cancer MDA-MB-231 cells treated with genistein. Results The results of MTT assay showed that genistein inhibited the viability of breast cancer MDA-MB-231 cells in a time- and concentration-de-pendent manner. Colony assay suggested that genistein had an antiproliferative effect on MDA-MB-231 cells. The expression levels of Bcl-2, NF-κB and p-ERK were significantly down-regulated compared with con-trol(P < 0.01). However, the expression of Bax, caspase-3 and p-JNK was significantly up-regulated(P<0.01). Conclusions Genistein could inhibit the growth of human breast cancer MDA-MB-231 cells and induce apoptosis,and the mechanism may be related to the inhibition of NF-κB, ERK/MAPK signaling path-ways and the activation of JNK/MAPK signaling path-way.
