Objective To investigate the clinical efficacy of combined use of acupuncture and medicine in treating spasmodic torticollis.Method Thirty patients were randomly allocated to a treatment group of 15 cases and a control group of 15 cases. The treatment group received combined use of acupuncture and medicine, and the control group, acupuncture alone.Result Clinical observation lasted one year. There was a statistically significant pre-/post-treatment difference in the Tsui score in the two groups at 6 and 12 months after treatment (P<0.01). There was a statistically significant difference in the Tsui score between at 6 and 12 months after treatment in the two groups (P<0.01); the Tsui score decreased gradually after treatment. There was a statistically significant post-treatment difference in the Tsui score between the two groups at 12 months after treatment (P<0.05); the Tsui score decreased more in the treatment group.Conclusion The cure and marked efficacy rate of combined use of acupuncture and medicine for spasmodic torticollis is higher than that of acupuncture alone. A longer course is needed for acupuncture treatment of spasmodic torticollis and the patient should persevere with the treatment.

BACKGROUND: Femoral head necrosis can be induced in adult rabbits when a large dose of steroid has been used for a long time. However, the pathogenesis of steroid-induced femoral head necrosis needs further study.OBJECTIVE: To probe into the mechanism of the disease by light microscope and transmission microscope from morphological perspective based on the model of femoral head necrosis in rabbits.DESIGN: A randomized controlled observation.SETTING: Laboratory of Morphology; Teaching and Research Division of Pathology; Laboratory of Surgery, Weifang Medical College.MATERIALS: The experiment was carried out at the Experimental Center of Morphology, Weifang Medical College, between March 2002 and March 2003. Totally 40 adult New Zealand white rabbits were randomly divided into control group (n=10), dexamethasone group (n=10) and horse serum group (n=20).METHODS: Control group was given intravenous injection of normal saline of 10 mL/(kg·d) for 7 consecutive days. Dexamethasone group was given intramuscular injection of dexamethasone of 10 mL/(kg ·d)for 7consecutive days. Horse serum group was given intravenous administration of horse serum of 10 mL/kg; 3 weeks later the same volume of horse serum was injected once again, followed intramuscular injection of dexamethasone of 10 mL/(kg·d)for 7 consecutive days. Inferior sections of cartilage of the femoral head necrosis in the experimental animals were obtained 5 and 10weeks later, and then histological and ultrastructural changes were observed under the light microscope and transmission microscope.MAIN OUTCOME MEASURES: ① Histo-morphological observation of the animals in each group. ② Ultrastructural changes.RESULTS: All the experimental animals survived and entered the result analysis. ① Histo-morphological observation: The cells of inferior sections of cartilage of the femoral head necrosis of the experimental animals in control group were arranged regularly and had a small volume of elliptical bone cells. The cell body was located at bone lacuna, blood vessel arranged well in the medullary cavity of bone. Lesion haracteristics of femoral head in dexamethasone group and horse serum group were similar:Hematopoietic adipose in the medullary cavity of bone was significantly decreased while fat adipose obviously increased; bone trabecula of metaphysis and the inferior sections of cartilage of femoral head were found with ered, and so was the bone nucleus. The number of lacuna of bone was increased. ② Ultrastructural changes: Normal bone cells in control group were elliptical, located at bone lacuna. Nucleus was at one end of the cell with complete karyotheca and many mitochondria in the cytoplasm. In dexamethasone group and horse serum group there were lipid droplets in the osteocytes, narrowed blood capillary in the medullary cavity of bone and injured vascular endothelial cells.CONCLUSION: Corticotropin can induce necrosis of femoral head; the hormone causes accumulated fat adipose in the medullary cavity of bone.The increased internal pressure in the medullary cavity leads to ischemia of femoral head, thus inducing the necrosis of osteocytes.

Objective To detect the clinical value of evaluating myocardial viability in patients with old myocardial infaretion(OMI) by measuring myocardial isovolumie contraction motion indices with tissue Doppler imaging(TDI) under the quiescent condition. Methods The myocardial isovolumic contraction motion indices of 30 normal subjects and 30 patients with OMI were examined by TDI. The sample gate was located at left ventricular postero-septal,lateral,anterior,inferior,antero-septal and posterior walls in basal and middle segments separately. The peak positive and negative veiocities(VIVC1 ,VIVC2 ) during myocardial isovohimic contraction phase, and the difference(DIVC) between VIVC1 and VIVC2 were measured, which were analysed combined with the viable fraction(VF) calculated by single photon emission computed tomography (SPECT). Results VIVC1, DIVC were significantly decreased,and VIVC2 was significantly increased in infarct zones of patients with OMI than those of the normal subjects( P <0.05). Compared with normal subjects, myocardial isovolumic contraction motion indices of non-infarct wails in patients with OMI were steady( P >0.05). In OMI group,DIVC of short axis was significantly decreased than that in long axis( P <0.05). Statistic analysis showed that DIVC values on both of short and long axis had significant positive correlations with VF derived from SPECT,and the correlation coefficients were 0. 837 ( P<0. 001) and 0. 797( P<0. 001 ) ,respectively. The sensibility and specificity of evaluating viable myocardium was 75% and 75% separately supposing the cutoff of DIVC on short axis was more than - 1.50,and the sensibility and specificity was 77. 8% and 87.5% separately if the cutoff of DIVC on long axis was more than 0.92. Conclusions Myocardial isovolumic contraction's TDI of infarct zones in patients with OMI had characteristic changes. DIVC on both of short and long axis could be as a new method of evaluating myocardial viability.

After the treatment, the BBS score showed significant intra-group differences in both groups (P<0.01); the between-group comparisons showed that there were significant differences in comparing the scores of cerebella and brainstem subtypes after the treatment (P<0.05).ConclusionXing Nao Kai Qiaoneedling method plus Frenkel's rehabilitation exercise can effectively improve the symptoms of poststroke lower-limb ataxia, especially for cerebella and brainstem subtypes.

Objective:To prepare ultrasound-responsive nanodroplets with block polymer PEG-PCL as shell and perfluoropentane (PFP) as core, and study the effects of mechanical index (MI) on contrast-enhanced imaging properties of nanodroplet.Methods:PEG-PCL micelles were first prepared by dialysis, and then the micelles were mixed with PFP for emulsification to obtain nanodroplets. The particle size and zeta potential of nanodroplets were measured, and the morphology of nanodroplets were observed using transmission electron microscope (TEM). The stability of nanodroplets after storage at 25 ℃ and 37 ℃ was investigated. The phase transition and contrast-enhanced imaging of nanodroplets in vitro under a series of mechanical index (MI) were studied using an ultrasound diagnostic instrument.Results:The particle size of the nanodroplets was (356.6±5.6)nm, and the zeta potential was -(7.30±0.14)mV. The nanodroplets were close to spherical under TEM and had a clear core-shell structure. The particle size and dispersion of the nanodroplets increased after storage at 37 ℃ and 25 ℃. For imaging in vitro, no acoustic signal were observed at 25 ℃ when the MI varied from 0.08 to 1.0. At 37 ℃, acoustic signals were observed when MI≥0.4, and the intensity was stronger for higher MIs.Conclusions:The contrast-enhanced imaging of nanodroplets are closely related to the MI, and a higher MI could induce the phase transition of more nanodroplets and produce stronger contrast enhancement. This study could provide basis for the application of polymeric nanodroplets in ultrasound diagnosis and targeted therapy.

It was to introduce professor 's experience in the treatment of oculomotor nerve palsy with acupuncture based on the interactions of twelve muscle regions and opposing needling theory. In the treatment, the TCM syndrome differentiation is taken as the general principle, the theory of the interactions of twelve muscle regions and opposing needling as the specific feature. The contrary needling is used at Hanyan (GB 4) and Juliao (ST 3) on the healthy side. The meridian-collateral and the exterior-interior differentiations are adopted to identify the syndromes. At the early stage of the disease, the treating principle focuses on expelling wind, eliminating cold and promoting the circulations of meridians and collaterals. The shallow needling, less acupoints and gentle stimulation are required. At the middle and late stage, the treating principle concentrates on strengthening the antipathogenic and harmonizing and blood. The deep needling, the multiple acupoints and the strong stimulation are applied. Additionally, the four-needling technique at Fengchi (GB 20), the multiple shallow needling at the eyelid margin, the opposing needling and the quantity of needling sensation are used in combination, which were developed by professor . With those comprehensivemethods, the symptoms of oculomotor nerve palsy are relieved and the significant clinical therapeutic effects achieved.
