BACKGROUND: Vertebrobasilar transient ischemic vertigo (VBTIV) is the signal of cerebral apoplexy, which is mostly contributed to arteriosclerosis and can be the pre-symptom of cerebral infarction. 1/3 cases will suffer from cerebral infarction with its natural development in several years.Specially, it is the critical stage in 1-6 months after the 1st transient ischemic attack, for which, early treatment is especially important for it.OBJECTIVE: To observe the effects of time treatment on VBTIV and its regulation on blood lipid, lipoprotein and apolipoprotein (Apo).DESIGN: Complete randomized groups and controlled comparison.SETTING: Department of Traditional Chinese Medicine in Medical College of Qingdao University.METHODS:① Totally 66 inpatients of VBTIV were selected from Department of Traditional Chinese Medical of Songshan Hospital Affiliated to Medical College of Qingdao University from January 2003 to June 2004, of which, 47 cases were male and 19 cases female. All of the patients were in the known of the observation. Two groups were randomized, named timingment group,at certain time division(7:00 am-9:00 am),warming acupuncture was applied on Zusanli (ST 36), once everyday, needle retaining for 20 minutes each time. Besides, gegen tongluo tang was oral-administrated warmly in combination, one dose each day at the specific time division, 10 days made 1 course of treatment. In the control, except at the time division, the treatment was given at any time with the same method as the timing-treatment group. Before and after treatment, enzymatic method was used to assay total cholesterol (TC), triglyceride (TG), Apo-A1 and Apo-B100; the precipitation was applied to assay high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C). The therapeutic effects were evaluated at the end of 3-course treatment.③ χ2 and t tests were applied for the difference comparison of counting and measurement data.MAIN OUTCOME MEASURES:① Change of blood lipid before and after treatment in two groups.② Comparison of therapeutic effects after treatment between two groups.RESULTS:Totally 66 cases of VBTIV were all in result analysis.① At the end of 3-course treatment, the rate of significant improvement in timing-treatment group was higher remarkably than the control [79% (30/38),43％ (12/28), P ＜ 0.01].② Compared with the results before treatment and those after treatment in the control, the results of TC, TG, LDL-C,VLDL-C, Apo-B100 were lower remarkably (P ＜ 0.05-0.01) and the results of HDL-C and Apo-A1 were higher remarkably (P ＜ 0.05-0.01) after treatment in timing-treatment group. In the control, compared with the results before treatment, the results of TC, TG, LDL-C and Apo-B100 were lower remarkably (P ＜ 0.05-0.01) and the result of HDL-C was higher remarkably:CONCLUSION: The therapeutic effects of timing acupuncture in combination with medication are advantageous significantly compared with routine treatment on VBTIV and timing treatment reduces blood lipid much more effectively.

Objective: To observe the therapeutic effect of treatment at selected time on acute ischemic apoplexy and changes of hemorheologic indexes. Methods: 58 cases of acute ischemic apoplexy were randomly divided into a group of treatment at selected time (observation group) and a group of treatment at any time (control group). The observation group were treated by moxibustion at Zusanli (ST 36)and Shenque (CV 8)at Chen hours (7-9 o'clock am)each day, 20min each session, in combination with Chinese drugs Tongluo Decoction, one dose daily, oral administration, once at Chen hours. The control group were treated by the same methods at any hours except Chen hours. The therapeutic effects were assessed after 3 treatment courses. Hemorheologic indexes were determined before and after treatment in both groups. Results: The cured rate and the markedly effective rate in the observation group were better than those in the control group (P

BACKGROUND:The hair fol icle stem cells are usual cultured in Dulbecco’s modified Eagle’s medium/Ham’s nutrient mixture F-12 containing 10%fetal bovine serum. Recently, keratinocyte serum-free medium has been used to culture hair fol icle stem cells.
OBJECTIVE:To observe the effects of three different culture media on the proliferation and purity of hair fol icle stem cells.
METHODS:After sterling, the skin of the rat’s beard was cut off, and the vibrissa fol icles were dissected under a stereocroscope. The fol icles were digested by Dispase Ⅱ firstly and by the mixture of trypsin and EDTA secondly. cellsuspension was divided into three pieces based on the average number of cells and respectively cultured by keratinocyte serum-free medium, Dulbecco’s modified Eagle’s medium/Ham’s nutrient mixture F-12 containing 10%fetal bovine serum and keratinocyte serum-free medium containing 10%fetal bovine serum. Hair fol icle stem cells were selected by rapid adherence on col agen type Ⅳ, and passaged.
RESULTS AND CONCLUSION:Cultured hair fol icle stem cells spread to the third generation, and trypan blue assay showed there was no difference in cellsurvival rate among the three groups (P>0.05). cellCounting Kit 8 assay showed that the cells grew slowly in the three groups in the first 2 days. At day 4, the hair fol icle stem cells grew into the growth logarithmic phase, and the proliferative activity was ranked as fol ows:keratinocyte serum-free medium+10%fetal bovine serum>Dulbecco’s modified Eagle’s medium/Ham’s nutrient mixture F-12+10%fetal bovine serum>keratinocyte serum-free medium with a significant difference between the three groups (P<0.05). Flow cytometric examination showed the expression of CD34 in the keratinocyte serum-free medium+10%fetal bovine serum group was lower than that in the keratinocyte serum free medium group (P<0.05). The expressions of CD34, CK15 andβ1-integrin (CD29) in the Dulbecco’s modified Eagle’s medium/Ham’s nutrient mixture F-12+10%fetal bovine serum were lower than those in the other two groups (P<0.05). These findings indicate that we can obtain higher purity hair fol icle stem cells in the keratinocyte serum-free medium+10%fetal bovine serum than in the Dulbecco’s modified Eagle’s medium/Ham’s nutrient mixture F-12+10%fetal bovine serum.
