Objective To study the effects of Aralia chinesis on the proliferation and viability of fibroblasts and on the production of the hyaluronic acid(HA)in the cultured supernatant,and to explore its anti-hepatofibrosis mechanism.Methods NIH3T3 fibroblasts,which were cultured in vitro by routine method and were used as the substitutive model of hepatic stellate cells(HSC),were cultured with the rats serum containing Aralia chinese.The effects of Aralia chinesis serum on the cell proliferation was measured by methabenzthiazuron(MTT)assay and the HA content in cultured supernatant was detected by radioimmunoassay.Results Aralia chinesis serum showed no significant toxicity on NIH3T3 fibroblasts.5 %concentration serum of Aralia chinesis inhibited the cell proliferation and the synthesis of HA significantly(P

BACKGROUND: It is indicated in a large amount of basic researches that compound danshen di wan has a certain action on removing carotid atherosclerotic plaques (CAP), but there is lack of large sample data in randomized, controlled, multi-central clinical experiment.OBJECTIVE: To observe the removing action of compound danshen di wan on CAP, compared with aspirin.DESIGN: Multi-central, randomized controlled experiment was designed.SETTING: Research Center of Traditional Chinese Medicine and Ultrasonic Department of Xinjing Hospital, Fourth Military Medical University of Chinese PLA; Department of Traditional Chinese Medicine of Second Clinical Hospital, Xi' an Jiaotong University and Department of Cardiac Internal Medicine of Xi' an Hospital of Traditional Chinese Medicine.PARTICIPANTS: Totally 162 cases were selected from the clinic of Research Center of Traditional Chinese Medicine, Fourth Military Medical University of Chinese PLA; Department of Traditional Chinese Medicine, Second Clinical Hospital, Xi' an Jiaotong University and Department of Cardiac Internal Medicine of Xi' an Hospital of Traditional Chinese Medicine from 2002 to 2004, aged varied from 40 to 80 years, the thickness of carotid internal media ≥ 1.2 mm. They were randomized into two groups, named danshen di wan group of 89 cases(cases of soft plaque and hard plaque were 49 and 40 respectively) and aspirin group of 73 cases(cases of soft plaque and hard plaque were 42 and 31 respectively).METHODS: In danshen di wan group: compound danshen di wan was administrated orally(10 pills/time, 3 times/day), in aspirin group, enteric soluble aspirin table was administrated orally(75 mg/time, once a day),continuously for 6 months. The alternations of thickness of carotid internal media were determined with ultrasonic B of high resolving power before and after treatment.MAIN OUTCOME MEASURES: Changes in thickness of carotid internal media before and after treatment.RESULTS: By practical measuring analysis, 143 cases accomplished nation of thickness of carotid internal media in the patients with soft plaque:In danshen di wan group, the thickness was remarkably decreased after treatment[ (2. 12 ± 0. 34), (2.44± 0.40) mm, t = 4. 267, P < 0.01 ] . In aspirin group, it was also reduced relatively after treatment[ (2.25 ± 0. 3),of carotid internal media in the patients with hard plaque: The changes were not significant no matter in danshen di wan group or aspirin group in the comparison before and after treatment[in danshen di wan group: (2.46 ±0.42),(2.34 ± 0. 40) mm; in aspirin group: (2.42 ± 0. 44), (2. 36 ± 0. 38) mm,P> 0.05].CONCLUSION: Compound danshen di wan acts on removing soft atherosclerotic plaque and its effect is similar to aspirin.

Objective To evaluate the action research method in the effect of swallowing disorder in patients with tongue cancer recovery path. Methods Based on the recovery path construction, according to the questions, plan, action, observation and reflection, improvement of summarizing the research process, through two stages of the research, assessment, diagnosis, planning, implementation, evaluation and comparison of stage 1 and stage 2 swallowing disorder in patients with rehabilitation evaluation, quality of life score, spirit to adapt to the score. Results Nearly 79.69% (51/64) of first phase swallowing rehabilitation effectively, and 93.75% (60/64) effectively in the second stage. Compared to the first stage,the second stage had an obvious increase. Two stages at the university of Washington Quality of Life Score, the first phase of (770.400 ±87.299) points, (1117.100 ± 43.153) points in the second stage, two stages of life quality score comparison, the difference was statistically significant (t=-19.500, P=0.012). The comparison of two stage patients mental adjustment scale scores, the first phase of (15.933±1.285) points, (31.733±2.083) points in the second stage, two stages score spirit to adapt to the comparison, the difference was statistically significant (t=-35.357, P=0.003). Conclusions Tongue cancer patients with swallowing disorder treatment on the basis of action study method to build and implement path specification, can improve the quality of care and quality of life of patients.

Objective To explore the mechanism of percutaneous laser disc decompression (PLDD) for treating prolapse of intervertebral disc. Methods 15 rabbits were divided into 3 groups randomly: sham group, model group with PLDD treatment, model group without PLDD treatment. The nerve conduction velocity (NCV) of L6 nerve root and the activity of phospholipase A2 (PLA2) in the intervertebral disc of L5-6 were determined 2 weeks after the initial surgery. Results NCV in the group with PLDD was significantly faster than that in the group without PLDD (P<0.001); NCV in the group without PLDD was significantly lower than that in the sham group (P<0.001). The activity of PLA2 in the group with PLDD was significantly lower than that in the group without PLDD (P<0.001); The activity of PLA2 in the group without PLDD was significantly higher than that in the sham group (P<0.001). Conclusion The activity of PLA2 in the herniated discs is higher than that in normal discs, which result in NCV falls remarkably. The PLDD can reduces chemical factors such as PLA2.
