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] Introducing the research on acupoints compatibility in recent ten years in order to discuss the research ideas. [Methods]Through retrieval of all medical journals of CNKI from Jan.2004 to Sep.2014,thirty-four articles were selected and analyzed. Summarizing and commenting the progress on compatibility mode, mechanism and action nature aspects.[Results]The research has summarized the characteristics of acupoints compatibility on ancient acupuncture literature and researched the clinical application of classic compatibility, discussed the mechanism of acupoint compatibility on the metabolism of biological molecules, the spectrum of endogenous metabolites and the central mechanism, confirmed the synergic and antagonistic effects of acupiont compatibility. There are some progresses but also deficiencies. [Conclusion]The acupoints compatibility research should change into clinical application, take multi discipline research methods and use different ideas. The relationship between acupoints quantity and effect of compatibility must be a research direction.

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.

AIM: To explore the possible role of the vitamin D receptor (VDR) in the effect of 1,25-dihydroxyvitamin D 3 and its novel analogues on a human osteosarcoma cell line (HOS-8603) proliferation. METHODS: Detecting the VDR mRNA and protein expression in HOS-8603 cells by reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemical analysis, respectively. Using the method of transient transfection of a reporter gene (DR3-tk-CAT) for VDR to detect its function. The cell VDRas3 which stably expressed VDR antisense mRNA was used to observe the effect of 1,25(OH) 2 D 3 on the proliferation of HOS-8603 cells and the induction of p21 mRNA, one of the VDR target genes, when the VDR in the cells was blocked. RESULTS: HOS-8603 cells expressed the vitamin D receptor which functioned as a hormone-dependent transcriptional factor. When VDR in the HOS-8603 cells decreased, the cells lost the responsiveness to 1,25(OH) 2 D 3 irrespective of either the induction of p21 gene expression or the cell proliferation. CONCLUSION: The effect of 1,25(OH) 2 D 3 on the proliferation of the human osteosarcoma cell line HOS-8603 was mediated by its nuclear receptor VDR.

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.

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.

Objective: Develop a kind of portable negative pressure calibrator by the design and implement of method. Methods:By the working principle of negative pressure sensor and gas flow sensor, the negative pressure aspirator realizes the calibration function and stability of the monitoring function of the pressure and flow. Results:Stating from the design concept, this portable negative pressure can satisfy the requirement of the quality control and test work. Conclusion:Guarantee the accuracy and efficiency in the clinical first aid and field battle when using attractor. This avoids attractor of iatrogenic injury accident caused by negative pressure fall off.

Objective To evaluate the role of thoracoscopy-assisted mini-incision in surgical treatment of lung tuberculosis.Methods From 1999 to 2004,pulmonary lobectomy was performed with thoracoscopy-assisted mini-incision(5-7 cm) on 42 patients with lung tuberculosis(right superior lobectomy in 16,right middle lobectomy in 4,right inferior lobectomy in 4,left superior lobectomy in 10,left lingular lobectomy in 4,and left inferior lobectomy in 4).Results None of the patients were converted to open surgery.The mean operation time was 105 min(35-170 min);blood loss ranged 100-800 ml(mean,150 ml).In the patients,thoracic drainage lasted for 1-5 d(mean,2.8 d) after the operation,and the hospital stay was 4-11 d(mean,6.7 d).During a 2-to 13-month follow-up(mean,8.2),no patient showed positive sputum,bronchopleural fistula,or diffusion of tuberculosis.Conclusions Since thoracoscopy-assisted mini-incision is assosiated with minimal tissue injury,few blood loss,quick postoperative recovery,short hospital stay,and few complications after the surgical treatment of lung tuberculosis,it is worth being widely used.For surgeons,it is important to remember the indications for the procedure.

The traditional Chinese culture is the common spiritual treasure for all Chinese nationalities.Therefore,the application of the rich resources of life values in traditional Chinese culture is of marvelous significance for medical students to better understand the value and meaning of life,and learn to fear,respect,and cherish life,in order to improve the quality of their own lives and establish the sanctity of life to commit their lifetime to the great cause of medical career.
