ObjectiveTo observe the effect of acupuncture combined with rehabilitation training on hemiplegia patients with shoulder pain. Methods100 patients were randomly divided into the treatment group (50 cases) and the control group (50 cases).The treatment group were treated by acupuncture combined with rehabilitation training, while the control group received rehabilitation training only. Scores of grade of shoulder pain and the Brunnstrom's classification of upper limbs in two groups were measured at pre-and-post treatment respectively. ResultsAfter treatment scores of grade of shoulder pain were less significantly (P<0.01), and the motor function of upper limbs improved to Ⅳ grade were more significantly (P<0.01) in patients of two groups . But the curative effect of the treatment group was better than that of the control group (P<0.05). Conclusions The treatment of acupuncture combined with rehabilitation training can improve the effect on hemiplegia patients with shoulder pain.

Objective To explore the accuracy and practicability of the three-dimensional ultrasound in real-time intellectual positioning navigation.Methods The phantom was applied in the real-time intellectual positioning guided biopsy of three dimensional ultrasound,free-hand ultrasound-guided biopsy and bracket-guided biopsy with different depths(5 cm,10 cm) and different sizes of the targets (6 mm and 15 mm).The time spent,the length of the sample and the success rate of biopsy were compared among three groups,and statistical analysis was done.Results ①The different sizes of targets with different depths were shown in three kinds of biopsy that the real-time intellectual positioning guided biopsy of three-dimensional ultrasound spent more time than bracket-guided biopsy,less than free hand ultrasound-guided biopsy.The difference was significant (P ＜0.05).The aquired red-dyed sample was longer in the real-time intellectual positioning guided biopsy of three-dimensional ultrasound compared to free-hand ultrasound-guide biopsy and bracket-guided biopsy,the difference was significant (P ＜0.001).②For real-time IP-guided biopsy of three-dimensional ultrasound with same depth,larger size of targets(15 mm) spent less time than smaller saize of targets (6 mm),the difference was significant (P ＜ 0.05).However,compared to smaller saize of targets(6 mm),success rate of biopsy in larger size of targets(15 mm) had no significant difference (P =0.238 at depth of 5 cm,P =0.479 at depth of 10 cm).③For real-time intellectual positioning guided biopsy of three-dimensional ultrasound with same size,time spent was less in the targets at the depth of 5 cm than in the targets at the depth of 10 cm,the difference was significant (P＜0.05).The aquired red-dyed sample was longer in the targets at the depth of 5 cm than in the targets at the depth of 10 cm,and success rate of biopsy in the targets at the depth of 5 cm was higher too (P ＜0.05).Conclusions The real-time intellectual positioning guided biopsy of three dimensional ultrasound spend less time with high accuracy and success rate of biopsy,especially for smaller and deeper targets,can be clinically applied with accuracy and practicability.

Objective To observe the expression of GATA-3 and IL-13 in mice with radiationinduced lung fibrosis,and to study the function of GATA-3.Methods A total of 63 C57BL/6 female mice were randomly into 2 groups,including 21 mice in control group and 42 mice in irradiated group.The thoraces of mice in irradiated group were exposed with 12 Gy of X-rays.All the mice were sacrificed at 1 h,and 1,2,4,8,16 and 24 weeks post-irradiation.The lung issues were stained by using HE and Masson methods to determine the histological changes.The expression of IL-13 in serum,and the expression of hydroxyproline and the mRNA and protein of GATA-3 in lung tissue were assayed.Results Compared with control group,there was a significant histological and pathologic change in irradiated group.The content of hydroxyproline in irradiated group was significantly higher than that in control group( Z =3.14,P ＜0.05).The expressions of GATA-3 and IL-13 were found in mice post-irradiation.Without causing conspicuous fibrotic pathological changes,there was a significantly elevated expression of Th2-specific transcription factor GATA-3 mRNA at 1 and 2 weeks post-irradiation ( t =6.50,6.33,P ＜ 0.01 ),while the expression of IL-13 reached the maximal value in serum at 16 weeks post-irradiation( t =32.21,P ＜0.01 ).Conclusions GATA-3 might play a role in promoting radiation-induced pulmonary fibrosis by upregulation of expression of Th2 cytokine IL-13.

Objective To analyse the characteristics of fundus fluorescein angiography(FFA)of iatrogenic retinal vascular occlu- sion.Design Retrospective case series.Participants 9 eyes of 9 patients with iatrogenic retinal vascular occlusion and 16 eyes of 16 patients with non-iatrogenic retinal vascular occlusion in Beijing Tongren Hospital in 2002-2005.Methods All patients were examined with FFA.The difference of circulation time of retinal vessels both in iatrogenic and non-iatrogenic retinal vascular occlusion patients was compared.Main Outcome Measures The starting perfusion time and the finishing time of retinal artery or vein.Results In pa- tients with iatrogenic(4 cases)and non-iatrogenic(12 cases)central retinal artery occlusion,the finishing perfusion time was separately 79.33?87.04s and 19.20?4.61s; the finishing time of retinal vein was separately 128.07?149.11s and 33.16?15.34s.In iatrogenic(4 cas- es)and non-iatrogenic(4 cases)central retinal artery together with central retinal vein occlusion patients,the finishing perfusion time of retinal artery was separately 211.67?371.26s and 30.07?17.26s;the finishing perfusion time of retinal vein was 232.43?358.52s and 48. 81?11.64s.One patient was ocular artery occlusion.FFA showed that choroidal background fluorescence and central artery were perfused slowly,the vascular fluorescence perfusion was interrupted before it came out of optic disk and the perfusion interruption continued until late stage with extensive peripheral non-perfusion areas.Conclusion The perfusion time of the retinal artery and vein in iatrogenic reti- nal vascular occlusion may be much longer than that in non-iatrogenic retinal vascular occlusion.

BACKGROUND: Schizophrenia is substantially heritable, but specific susceptibility genes remain difficult to be identified. Therefore, it is necessary to explore hereditary markers first.OBJECTIVE: To investigate the relationship between schizophrenia and related vWA allele genes based on the analysis of microsatellite DNA vWA polymorphism.DESIGN: A case-controlled study with schizophrenic patients and randomly selected population as subjects.SETTING: Ward of Dalian Seventh People's Hospital and Molecular Biological Laboratory of Dalian Medical University.between March and July 2002 at Dalian Seventh People's Hospital which specializes in schizophrenia. Schizophrenia was diagnosed according to the diagnostic standard of the third edition of "the American Diagnostic Statistical Manual for Schizophrenic Diseases", and their clinical manifestations were predominantly negative signs. Altogether 123 normal blood samples were collected from random population at the Blood Center of Dalian Red Cross. They all denied psychological ailments and severe systematic diseases, and they had no kinship with each other.METHODS: Heparin anti-coagulation blood samples were collected and PCR compound amplification was carried out with the aid of PE Profiler plus system. Then the products were subjected to electrophoresis and gene detection with ABI310 type gene analysis system so as to calculate the frequency of allele genes; Hardy-Weinberg equation law was used to make coincidence test and linkage analysis of the theoretical frequency and actual one. Schizophrenic patients and random population were compared and relative risk was calculated with RR=Pd × (1-Pc)/Pc × (1-Pd) in order to assess the statistical significance (RR: relative risk; Pd: gene frequency of schizophrenia; Pc: gene frequency of random population). RR ＞ 1 was considered of higher susceptibility while RR ＜ 1 was considered of anti-susceptibility. In this way, we could find out vWA allele genes that had susceptible linkage or anti-linkage with schizophrenic related genes.MAIN OUTCOME MEASURES: Major outcome: Correlation analysis of vWA allele genes in schizophrenic patients and random population. Secondary outcome: The coincidence of vWA allele gene frequency in patients with schizophrenia and random population with what was calculated by Hardy-Weinberg law.RESULTS: Data of the two groups were processed according to the objective and statistically analyzed.① vWA allele gene frequency in patients with schizophrenia and in random population was found to coincide with HardyWeinberg law(P ＞ 0.05).② The positive rate of vWA-14 in schizophrenic patients (17.2%) was obviously different from that in random population (33.3%) (RR=0.415, P=0.014). The positive rate of vWA-17 in schizophrenic patients (31.3%) was found to be significantly higher than that in random population (19.5%) (RR=1.866, P=0.043) while it did not differ significantly in other allele genes (P ＞ 0.05).CONCLUSION: The positive rate of vWA-14 was significantly lower in schizophrenic patients than in random population, indicating that vWA-14locus may be negatively selected in schizophrenia due to some reasons,which may be approximate to anti-schizophrenia genes. Moreover, the higher expression of vWA-17 in schizophrenic patients than in random population suggests that vWA-17 locus is correlated with schizophrenia,which may be approximate to schizophrenia-susceptibile genes.

Objective To define the expression of Shh/Gli1,the key elements of Hedgehog signaling pathway in papillary thyroid carcinoma(PTC) and to explore the relationship between the expression of Shh/Gli1 and clinical significance.Methods The expression of Shh and Gli1 was examined in 142 cases of PTC tissues and adjacent tumor thyroid tissues as control by immunohistochemistry.The relationship between the expression of Shh/Gli1 and clinical characteristics of PTC patients was analyzed.Results The positive rate of the cytoplasm Shh expression and the nuclear Gli1 expression was 64.1% and 47.9% ,respectively.Significant difference was found between normal thyroid tissues and PTC.The research showed that the expression of Shh/Gli1 was related to the tumor size,clinical stages and lymph node metastasis,Shh was more significantly related to the tumor size(P ＜0.01) and Gli1 was more significantly related to the lymph node metastasis (P ＜ 0.01).Conclusions Varying expression of the main ligand Shh and transcription factor Gli1 in Hedgehog signaling pathway was found in PTC.The expression of Shh/Gli1 was related to the tumor size,clinical stage and lymph node metastasis,indicating that the aberrant activation of Shh signaling pathway plays some roles in PTC.Shh/Gli1 may be indicators for prognosis and ideal targets for therapy against PTC.

Objective To establish mild cognitive dysfunction (MCI) models in elderly rats,and to investigate the pathophysiological features.Methods Totally 40 SD rats (14 to 18-month-old) were randomly divided into 2 groups:the model group (n=20) and the sham operation group (n=20).Bilateral carotid artery stenosis was prepared in the model group while bilateral carotid artery was seperated with no bilateral narrowing in the sham operation group.30 days after the operation,Morris water maze test was performed,pathomorphological and electron microscopic observations of the cerebral tissue were examined and the expression of G protein-coupled receptor kinase 2(GRK2) in hippocampus tissue w detected by reverse transcription polymerase chain reaction (RT-PCR) and Western blottin.Results The mortality in model group was only 10％.Pathological morphology and ultrastructure showed that hippocampal tissue structure was almost normal in sham operated group,but in model group group,hippocampal CA1 pyramidal cells were in ischemic demyelination,arranged loose,and part of the cells showed nucleus pyknosis,deeply stained; there was no obvious infarct in white matter,part of the white matter fiher hecame thinner and disorder,nucleolus became smaller and steped aside,cytoplasmic electron density increased,lipofuscin appeared occasionally.Rough endoplasmic reticulum and Golgi were expanded,cytosolic free ribosomes increased,part of mitochondria became swelled,vacuolated.Morris water maze test results showed that the average escape latency in model group was longer than in sham group (P＜0.05).In spatial probe test,the average time of crossing the first original platform in model rats was significantly longer than the sham operated group [(36.80±7.68) s vs.(20.87±6.16)s,P＜0.05].The average number of crossing the original platform in 60 seconds in model group was significantly less than in sham group(1.43±0.51 vs.3.10±1.45,P＜0.05).The expressiones of GRK2 mRNA and protein in the hippocampus were significantly increased in model group rats than in sham group (P＜0.05).Conclusions The model of severe CCA stenosis in elderly rats can be applied for MCI animal models with good stability and repeatability.Compared with sham group,the cells morphology and ultrastructure in model group appeare more obvious pathological changes and mild impairments in cognitive function.GRK2 may play an important role in the development of MCI.
