Objective To observe the clinical efficacy of micro-invasive point-through-point thread-embedding in treating acute stage of post-stroke shoulder-hand syndrome. Method Sixty patients were randomized into a treatment group and a control group, 30 in each group. Patients in the treatment group were intervened by micro-invasive point-through-point thread-embedding in addition to rehabilitation training, while patients in the control group were by rehabilitation training alone. Before treatment and after 4-week treatments, Visual Analogue Scale (VAS) was used to estimate shoulder pain, modified Barthel Index (MBI) to detect the activities of daily life, and Fugl-Meyer Assessment Scale to measure the motor function of upper limb. Result Before treatment, there were no significant differences in comparing the involved indexes between the two groups (P>0.05), and the indexes were significantly improved after intervention in both groups (P<0.05). Conclusion Micro-invasive point-through-point thread-embedding can reduce pain intensity, improve the activities of daily life and motor function of upper limb of patients in acute stage of post-stroke shoulder-hand syndrome.

Objective To investigate the correlation among Lp (a),cerebral infarction and carotid atherosclerosis.Methods 180 cases were equally divided into 3 groups (60 cases in each group).The patients with both cerebral infarction and carotid atherosclerosis composed one group(cerebral infarction group for short) ;the patients of carotid atherosclerosis which without cerebral infarction composed another group(no cerebral infarction group for short) ;the control group composed with those who had neither cerebral infarction nor carotid atherosclerosis.The level,outlier detection rate about Lp(a) and usual risk factors of cerebral infarction were compared in this research.Results The level and detection rate of Lp(a) in the cerebral infarction group were (512 ± 156) mg/L and 46.7％ ;the level and detection rate of Lp(a) in the no cerebral infarction group were (316 ± 87)mg/L and 20.0％ ;the level and detection rate of Lp(a) in the control group were (199 ± 123) mg/L and 5.0％.The differences of the level and outlier detection rate of Lp(a) among the three group were significant(F=13.87,x2 =29.394,P ＜0.01).Cerebral infarction patients had more usual risk factors of cerebral infarction (hypertension,diabetes,hyperlipemia,drinking,smoking,obesity and lack of exercise) than those who without cerebral infarction (x2 =15.523,P ＜ 0.01).Conclusion The abnormal of Lp(a) was an important risk factor of cerebral infarction.The general survey of Lp(a) was significant in the primary and secondary prevention of stroke.To the people whose assay of Lp(a) was abnormal,the control of governable risk factors of cerebral infarction should actively be carried out.

Objective To investigate the distribution of blood pressure and incidence of hypertension in children and adolescents from the urban area of Guiyang city aged 8-17 years old,in order to provide scientific evidence for preventing hypertension.Methods Seven thousand nine hundred and sixty-three primary and secondary students were sampled and standardized in blood pressure,height and weight.In accordance with the Working Group on Obesity in China(WGOC)recommendations,the subjects were divided into overweight,obesity and normal weight group,then the relationship between blood pressure and body mass index(BMI)and the prevalence of hypertension in different BMI groups were analyzed.Results 1.Compared with the USA and Shanghai city,the distribution of blood pressure in children and adolescents from the urban area of Guiyang city were different(Pa

Limb-shaking transient ischemic attack (TIA), a rare manifestation, is commonly caused by severe stenosis or occlusion of an extracranial internal carotid artery. Such patients are usually treated with surgical revascularization or anti-platelet therapy. We present a 56-year-old woman with 6 months’ episodic attacks starting with mouth skewed to the right and a sensation of ‘weakness’ involving predominantly her left arm, and at times, also involved the left leg. This was immediately followed by rhythmic jerky movements of the left arm and at times, also involved the left leg. Magnetic resonance angiography revealed severe stenosis of M1 segment of the right middle cerebral artery. The patient’s symptoms were signifi cantly improved by treatment with anti-platelet drugs and nimodipine.

The bioactivity of a working reference standard was determined by replicate bioassays with calibration against a primary reference standard. In this study the number of bioassay replicates needed for calibration first was calculated theoretically, and if the mean value of the experimental bioassay replicates fell within the predefined bioactivity level the bioactivity of the working reference was defined as 100%. Our results showed that when the total intermediate precision of the bioassay method was at 11.66% and the predefined bioactivity level was set at 95%-105% with a confidence level of 95%, 21 bioassay replicates should be carried out for calibration. The average value of the 22 experimental bioassay replicates was 101.96%, so the bioactivity of the working reference standard was consistent with that of the primary reference standard at 100%. The results suggest that a strategy of first calculating the number of bioassay replicates needed for calibration and then determining whether the resulting experimental mean value is within the predefined bioactivity level will be of value to the biopharmaceutical industry.

Objective To study the changes of Na+K+-ATPase,Ca2+Mg2+-ATPase activities in erythrocyte membrane and blood viscosity in children with essential hypertension.Methods The activities of Na+K+-ATPase,Ca2+Mg2+-ATPase in erythrocyte membrane were determined by a colorimetric method.Blood viscosity was measured and analyzed with the statistic analysis SPSS 12.0 software in 50 children from Nov.2004 to Dec.2004 in the people's hospital of guizhou province and adolescents with essential hypertension.Thirty healthy children were collected as control group.Results The activities of Na+ K+-ATPase[(6.12?1.30)?molpi/(gHb?h)and(4.59?1.40)?molpi/(gHb?h)],Ca2+Mg2+-ATPase[(7.46?1.30)?molpi/(gHb?h)and(5.81?1.20)?molpi/(gHb?h)] were lower significantly in hypertension group than those in control group(Pa

Objective To explore the hemorheological changes in children with essential hyepertension,and explore their clinical significance.Methods The hemorheological parameters,blood lipid,blood glucose in 37 children with essential hyepertension [19 boys and 18 girls,median age(12.49?3.20) years] were measured and analyzed.The parameters in 30 healthy children were measured as controls.SPSS 11.5 software was used to analyze the data.Results The whole blood viscosity under high,middle and low shear rate,plasma viscosity,hematocrit,rigidity index of erythrocyte,platelet aggregation M were significantly higher in hypertension group than those in healthy control group(Pa0.05).Conclusions There have been developed significant hemorheological changs in children with essential hypertension.The hemorheological changes might play an important role in pathogenesis of childhood hypertension.

Objective To study the construction of the lentiviral-mediated RNA interference(RNAi) vector targering rat suppressors of cytokine signaling 3(SOCS3) gene.Methods Three target sequences were selected by on-line designer software on Ambion according to rat SOCS3 mRNA sequence(NM053565),the complementary DNA contained both sense and antisense oligonucleotides were designed and synthesized.After annealing,these double strands DNA were cloned to pRNA-Lenti-green fluorescent protein(GFP),which contained U6 promoter and GFP.The resulting Lentiviral vector containing SOCS3 shRNA was named pRNA-Lenti-SOCS3-GFP.After the rat glioma cells(C6)were transduced with the constructed 1entiviral vectors,real-time polymerase chain reaction was used to evaluate the level of SOCS3 expression(including siRNA1 group,siRNA2 group,siRNA3 group,vacuity group and siRNA-Negative group).The pRNA-Lenti-SOCS3-GFP and Lentivector Pakaging plasmid mix were cotransfected into 293T to package Lentivirus particles.Culture supematant was harvested,then the virus titer was determined by serial dilution assay.Results The SOCS3 mRNA sequence was successfully cloned to pRNA-Lenti-GFP,which was proved by PCR and DNA sequence.Compared with control group,the SOCS3 mRNA expressions were obviously suppressed in all 3 experimental groups,especially the expression rate in siRNA1 group was reduced by 80%.The Lentiviral particle titer was determined by serial dilution assay with 1.0?1010 TU?L-1.Conclusion The lentiviral-mediated RNAi vector of rat SOCS3 gene has been constructed successfully,this may provide a potential tool for studying and treating SOCS3-related diseases.

Objective To compare the effect of different needle-retaining time on post-stroke hypermyotonia in acupuncture treatment.Method Ninety patients with post-stoke hypermyotonia were randomized into group A, group B, and group C, 30 in each group. The three groups were all treated by the twelve hand-foot needling method from the thirteen therapies invented by acupuncture master WANG Le-ting, once a day, 5 times a week, 20 times in total. For group A, needles were removed right after needling qi arrived; for group B, needles were retained for 30 min after needling qi arrived; for group C, needles were retained for 60 min after needling qi arrived. The modified Ashworth Scale (MAS), Clinical Spasticity Index (CSI), and Fugl-Meyer assessment scale (FAS) were adopted for observation before and after intervention.Result After treatment, the MAS was significantly changed in all three groups (P<0.05). The CSI score and FAS score of the affected limb were significantly changed in all three groups after intervention (P<0.05). Both group A and B were significantly different from group C in comparing the CSI and FAS scores (P<0.05).Conclusion Compared to retaining needles for 60 min, acupuncture without retaining needles or retaining needles for 30 min can produce better effect in improving post-stroke hypermyotonia, spasticity, and motions of limbs.
