Objective: To investigate the efficacy of the green tortoise exploring point technique for treating piriformis syndrome. Methods: Ninety patients were randomly allocated to a green tortoise exploring point treatment group of 30 cases, an acupuncture control group of 30 cases and a hydro-acupuncture control group of 30 cases for clinical observation. Results: The symptoms improved after treatment in all the three groups. The total efficacy rate was 100.0% in the treatment group, 76.7% in the acupuncture group and 83.3% in the hydro-acupuncture group. There were statistically significant differences between the three groups (P<0.01, P<0.05). Conclusion: The technique of green tortoise exploring point is better than conventional acupuncture and hydro-acupuncture in treating piriformis injury syndrome

Objective:To investigate the expression of estrogen receptor in genioglossus of female rats. Methods:30 female Sprague-Dawley rats were randomly assigned to three groups: normal group(NORMAL), sham operation group (SHAM) and ovariectomized group(OVX). The rats were sacrificed 6 weeks after surgery, and the genioglossus was removed for analysis. The expression of estrogen receptors(ER? and ER?) was examined by immunohistochemical assay. Results:ER? and ER? were found in genioglossus of normal rats. The expression of ER? was significantly higher than ER? (P0.05). Conclusions:Estrogen receptors are expressed in genioglossus of female rats.ER? expression is significantly impacted by the estrogen level.

Objective To investigate the changes of CT perfusion (CTP) imaging and the risk factors for CTP abnormality in patients with transient ischemic attack (TIA).Methods TIA patients were enrolled; CTP and CT angiography were performed.The parameter values of cerebral blood flow (CBF),cerebral blood volume (CBV),mean transit time (MTT),and time to peak (TTP) were obtained.CTP abnormalities were identified by comparing the contralateral mirror area.Demography and baseline clinical data were compared in a CTP imaging abnormal group and a normal group.Multivariate logistic regression analysis was used to identify the risk factors for CTP abnormality in patients with TIA.Results A total of 69 patients with TIA were enrolled,and 52 of them had perfusion abnormalities corresponding to clinical symptoms.Their TTP and MTT were prolonged,but the decreased CBF and CBV was not obvious.Multivariate logistic regression analysis showed that the higher National Institutes of Health Stroke Scale (NIHSS) score (odds ratio [OR] 1.991,95％ confidence interval [OR] 1.113-3.564; P=0.020),the longer duration of symptoms (OR 1.062,95％ OR 1.013-1.114; P =0.013),and intracranial vascular stenosis (OR 15.410,95％ OR 2.118-112.116; P=0.007) were the independent risk factors for CTP abnormality in patients with TIA.The correlation analysis showed that the prolonged TTP (r =0.389,P =0.001) and MTT (r =0.413,P=0.001) were significantly associated with the NIHSS score.Conclusions TTP and MTT may sensitivity reveal cerebral perfusion abnormalities in patients with TIA.The more severe the disease is,the higher the CTP abnormal rate will be.

BACKGROUND:Both in vivo and vitro microenvironment can influence the proliferation and differentiation of neural stem cells (NSCs). In addition, cell culture solution plays variable roles in cell proliferation and differentiation.OBJECTIVE:To develop a convenient and rapid method to promote NSC primary culture by modifying traditional serum-free medium. DESIGN, TIME AND SETTING:Randomized controlled cell trial was performed at Institute of Brain Science, Qingdao University Medical School from November 2005 to September 2006.MATERIALS:Ten Wistar rat of gestation for 12-16 days; cell suspension fron brain tissue of embryonic rat. METHODS:Cell suspension were seeded into four 50-mL culture flasks with cell density of 1×106 mL-1, and divided into 2 groups with 2 flasks in each group. The control cells (flasks A and B) were cultured in serum-free medium containing DMEM/F12, B27 (2%), basic fibroblast growth factor (20 μg/L), and epidermal growth factor (20μg/L), and the experimental cells (flasks C and D) were firstly cultured with DMEM/F12 containing fetal bovine serum (FBS, 5%), following by the same serum-free medium 2 to 3 days later. MAIN OUTCOME MEASURES:The proliferation of NSCs was observed by inverted microscopy and immunocytochemistry.RESULTS:①Most of the cells in two culture conditions expressed nestin, the specific marker of NSCs, and were immunocytochemically positive. ②Neural stem cells cultured with FBS formed neurospheres 3-4 days earlier than those without FBS. ③There were no significant differences in cell number, but the neurospheres under the experimental condition were larger than those in control group. Some of the cells were neurone specific enolase-positive after serum-conditioned induction, and some were glial fibrillary acidic protein-positive, indicating NSCs had differentiated into neuron-like cells and neurogliocytes.CONCLUSION:FBS-conditioned pre-culture can accelerate the proliferation of neural stem cells.

Objective To explore the method of comfort nursing in patients with nasogastric feeding and observe the influence on enhancement of patients satisfaction degree. Methods Case control study Was used in 162 conscious patients with nasogastric feeding.80 patients from January 2005 to January 2006 were selected as control group and given routine nursing.82 patients from February 2006 to May 2007 were named as the test group and received confort nursing.The satisfaction degree of patients, injury of nasal mucosa, shedding rate of the gastric tube and aspiration rate were investigated with self-designed discomfort questionnaires. Results The satisfaction degree in the test group Was 63.41％,which was higher than that of the control(40.00％,P＜0.01).The rate of nasal mucosa injury, shedding of the gastric tube and aspiration rate were lower in the test group(1.22％,2.44％,1.22％)than those in the control group(8.75％,10.00％,7.50％,P＜0.05).Conclusion The application of comfort nursing in patients with nasogastric feeding contributed to the enhancement of satisfaction degree of patients and nursing quality.

Objective To construct Streptococcus mutans UA159 mutants with deletion of LuxS gene related to quorum-sensing pathway and evaluate the aciduricity of the mutants. Methods Using S. mutans UA159 as materials, the PCR fragments of the upstream and downstream regions of LuxS and erythromycin resistance(Eymr) gene of PJT10 were cloned into plasmid PUC19. The resulting constructs were integrated into the chromosome of S. mutans. LuxS gene deletion mutant was then constructed in S. mutans by means of allelic exchange and selected for resistance to erythromycin. The aciduric ability of the mutant under different pH was measured and S. mutans UA159 was used as control. Results The LuxS-deleted status of S. mutans mutants were confirmed by various PCR and DNA sequencing. The results showed that Eymr gene take the place of LuxS gene, while the mutant can not induce bioluminescenece. The LuxS mutant strain displayed a decreased growth ability with the decreasing pH values compared to those of the wild-type strain UA159. Conclusion A LuxS-negative mutants of S. mutans is constructed. The LuxS quorum sensing system is involved in the regulation of aciduricity of S. mutans UA159.
