Objective To observe the expressions of transforming growth factor-?1(TGF-?1) and plasminogen activator inhibitor-1(PAI-1) mRNA in tubulointerstitial fibrosis( TIF ) rats,and explore the effects of TGF-?1 and PAI-1 on TIF and the interaction between TGF-?1 and PAI-1.Methods Sixty male SD rats were randomly divided into sham operation group (SOR group,n=30) and unilateral urethral obstruction group(UUO group,n=30).TIF model was established via UUO.At d 7,d 14,d 21 after operation,10 rats of every group were killed to obtain renal samples.Histological changes were observed in tubulointerstitium injury under microscope;mRNA and proteins of TGF-?1 and PAI-1 were detected by real-time PCR assays and Western blotting respectively at d 7,d 14,d 21 after experiment onset.SPSS 10.0 software was used to analyze data.Results 1.HE,Masson staining of renal tissues of all groups indicated that there were no fibrosis in SOR rats,there were vacuole degeneration in tubular epithelial cells and inflammatory cell infiltration in tubulointerstitial in UUO rats at d 7,fibrosis aggravated gradually and became severe fibrosis at d 21.2.The expression locations of TGF-?1 and PAI-1 were renal sites of fibrosis by immunohistochemical staining.The mRNA and proteins of TGF-?1 in rats from SOR groups were lower than those of UUO groups at d 7,d 14,d 21(P

Objective:To observe the efficacy of acupuncture at points of Shaoyang meridians plus moving cupping on neck and shoulder for migraine. Methods:A total of 64 migraine cases were randomly allocated into an observation group and a control group, 32 cases in each group. Random number table method was used in allocation. Acupuncture at points of Shaoyang meridians and cupping on neck and shoulder were used for cases in the observation group, which contain acupuncture 5 times a week and cupping once a week. Oral flunarizine hydrochloride capsules were used for cases in the control group, 10 mg for each dose, 1 dose a day. 2 weeks constitutes a course of treatment. The patients were treated for two courses of treatment in both groups. After that, the changes of visual analogue scale (VAS) and the migraine disability assessment questionnaire (MIDAS) were observed, as well as the clinical efficacy. Results:The total effective rate and recovery and marked effective rate in the observation group were 93.8% and 71.0% respectively, versus 78.1% and 43.8% in the control group, showing statistical significant differences (both P<0.05). There were significant decreases in VAS and MIDAS scores after treatments in both groups (both P<0.05). VAS and MIDAS scores in the observation group were significantly different from those in the control group (both P<0.05). Conclusion: Combining acupuncture at points of Shaoyang meridians and cupping on neck and shoulder can relieve headache and reduce influence of migraine on life. It can produce a better efficacy than oral flunarizine hydrochloride capsules in treating migraine patients.

Background It has not been reported that if the visual cortex M receptor changed during the development of myopia and how it changed if given acupuncture treatment.Objective The aim of this study was to observe the effect of electroacupuncture stimulation on the expression of acetylcholine receptors M1 (AchRM1) in visual cortex of guinea with lens-induced myopia (LIM).Methods Forty-eight three-week-old healthy guinea pigs were randomized into the normal control group,the LIM model group and the LIM electroacupuncture group.The right eyes of the guinea pigs were selected as the experimental eyes.LIM was created by monocularly wearing of-10 D lens for 4 weeks in the right eyes in the LIM model group and LIM electroacupuncture group,and then the acupuncture at the temple and hegu point was performed for 30 minutes per day for consequent 4 weeks,in the LIM electroacupuncture group.The fellow eyes of the guinea pigs were used as the self-control eyes.The refractive power and axial length were examined with retinoscopy and A-type sonography before and 4 weeks after modeling,respectively.The animals were sacrificed by excessive anesthesia at the fourth week after acupuncture and visual vertex tissue was obtained.The expression of M1 receptor mRNA in visual vertex was detected by fluorescence quantitative PCR,and the content of M1 receptor protein in visual vertex was assyed by ELISA.The study protocal was approved by Animal Ethic Committee of Shandong University of Traditional Chinese Medicine,and the use and care complied with Statement of the Association for Research in Vision and Ophthalmology.Results At the fourth week after modeling,the mean diopters were (-3.24±0.28) D and (-3.30±0.45) D in the LIM model group and the LIM eleetroacupuncture group,which were significantly higher than (0.83 ±0.86)D in the normal control group (both at P=0.000),and there was no significant difference in the diopter between the LIM model group and the LIM electroacupuncture group (t =0.200,P =0.659).The mean axial lengths were (8.67 ±0.14) mm and (8.60±0.06) mm in the LIM model group and the LIM electroacupuncture group,which were considerably increased in comparison with (8.33±0.08)mm in the normal control group (both at P＜0.05).The relative expression levels of AchRM1 mRNA in visual cortex were 0.79±0.18,1.36±0.23 and 1.13±0.13 in the normal control group,LIM model group and LIM electroacupuncture group,and the relative expression level of AchRM1 mRNA in the LIM electroacupuncture group was significantly higher than that of the normal control group and lower than that of the LIM model group (both at P＜0.05).In addition,the contents of AchRM1 receptor protein in the visual cortex were 248.00±33.31,455.17±42.40 and 396.17±47.57 in the normal control group,LIM model group and the LIM electroacupuncture group,with a similar pattern among the groups (both at P＜0.05).Conclusions A electroacupuncture stimmulation do not affect the myopic diopter and axial length in LIM model.The AchRM1 and AchRM1 receptor in the visual cortex up-regulate in LIM eyes,infering that electroacupuncture stimmulation can improve vision by decreasing the level of AchRM1 receptor in visual cortex in LIM eyes in guinea pigs.

ObjectiveTo investigate the clinical efficacy of combined traditional Chinese and western medicine for treatment of patients with deep venous thrombosis(DVT)in lower extremity.Methods A retrospective study was conducted. Forty patients with DVT admitted into Mindong Hospital Affiliated to Fujian Medical University were randomly divided into control and treatment groups, 20 cases in each group. Conventional therapy was given in both groups. The patients in control group were hypodermically injected with low molecular heparin 3.075 kU, and orally took warfarin sodium; the former injection was terminated on the 3rd day, and afterwards warfarin was solely administered. On the basis of the treatment in the control group, the patients in treatment group were additionally treated with Huoxue Tongmai decoction(ingredients: peach kernel 15 g, red paeonia 15 g, honeysuckle flower 15 g, rhizoma alismatis 12 g, semen coicis 30 g, semen plantaginis 9 g, suberect spatholobus stem 12 g, radix scrophulariae 9 g, pawpaw 12 g, radix achyranthis bidentatae 12 g), the formula could be modified in accordance with patients' symptoms and signs, and Jiangjun powder was applied at the lesion externally(ingredients of the powder: rhubarb 250 g, mirabilite 200 g, flour 100 g, vinegar 500 g were mixed to form a smooth paste), once a day, 30 days constituting a therapeutic course and totally 2 courses being taken. The perimeter of the affected limb, visual analogy score(VAS), revascularization rate, curative effect and adverse reaction were observed before and after treatment and compared between the two groups.Results The total effective rate in treatment group was higher than that in control group〔90.0%(18/20) vs. 70.0%(14/20),P<0.05〕. After treatment, the perimeter of the affected limb in both groups was significantly smaller than that before treatment, the decrease in treatment group being more marked〔the upper leg(cm):46.21±4.80 vs. 53.18±4.45, the lower leg(cm): 32.57±4.26 vs. 36.21±5.01, bothP<0.05〕. TheVAS scores were significantly decreased in both groups after treatment for 1 month, they reached the valley values after treatment for 2 months, the degree of descent being more significant in the treatment group(2.24±0.58 vs. 3.36±0.61,P<0.01). The revascularization rate of the treatment group after treatment was higher than that of the control group〔85.0%(17/20) vs. 70.0%(14/20),P<0.05〕.ConclusionThe combined treatment of traditional Chinese and western medicine was obviously superior to the sole western medicine for treatment of patients with DVT.
