The method of acupuncture combined with rehabilitation training in the treatment of shoulder hand syndrome after stroke is reliablet, quick, with simple operation and less adverse reactions. Among them, characteristic acupuncture could focus on the targeted points with obvious effect than ordinary acupuncture, and the combination with rehabilitation training could greatly improve the curative effect. However, there still exist some problems in the current research, such as the difficulty of conducting blind clinical trials of acupuncture therapy; the lack of follow-up data in the evaluation of curative effect, the uncertainty of long-term curative effect; the small sample size of clinical research, etc., so multi-centered and large sample RCT research are still needed.

BackgroundPosterior capsule opacification(PCO) is the main cause inducing low vision after extacapsular cataract extraction. Our previous study determined that polylysine-ethylene diamine tetraacetic acid (EDTA) (PLE) can suppress the incidence of PCO. ObjectiveThe goal of this experiment was to investigate the inhibition of polylysine-EDTA on rabbit lens epithelial cells (LECs)proliferation in vitro and the effective concentrations of polylysine-EDTA. MethodsThe anterior capsular membranes from 10 3-month-old clean New Zealand white rabbits were digested and then cultured to obtain the LECs. The second and third generation of LECs were inoculated on the 96-hole culture plate with the cell density of the 1 × 105/ml. 12.5,25.0,50. 0,100. 0 μmol/Lof PLE were added into the culture medium for 48 hours respectively,and the DMSO medium was used at the same way as the control group. The proliferation of the LECs was then detected by MTT method and the inhibitory rate of PLE on LECs growth was calculated. ResultsLECs grew at a near normal state in ≤25.0 μmol/L PLE groups,however,cultured LECs were out of shape and the numbers decreased with the weakened adhesion ability in ≥50.0 μ mol/L PLE groups. The A490 values of LECs were 0. 278±0. 013,0. 266±0. 028,0. 260±0. 022 and 0. 247±0. 012 in 12. 5,25.0,50. 0, 100. 0 μmol/L polylysine-EDTA groups respectively and were lower than 0. 311 ±0. 038 of DMSO control group( P=0. 035,0. 011,0. 009,0.013 ). The inhibitory rates of 12. 5,25.0,50. 0, 100.0 μmoL/L PLE on LECs proliferation were 10.61％ , 14.47％ , 16.40％ and 20. 58％ respectively. ConclusionsPolylysine-EDTA can inhibit the growth and proliferation of LECs in vitro at a dose-dependent manner.

Objective To investigate the effects of output power,action time and radiofrequency(RF) needle on the cool-tip radiofrequency ablation(RFA) by experimental tools and to determine the value of ultrasonography in size evaluation of RFA zone.Methods The cool-tip RFA to fresh calf liver were monitored by ultrasound.The experiments by single electrode needle were performed with different combination of output power (80 W,120 W) and time (5 min,8 min,10 min).The cluster needle was used for assessment at 5 min with different output power(80 W,120 W).After the end of trial,the longitudinal specimens were cut open.The view and size of the ablation zone were recorded with naked eyes.The pathological changes displayed by optical microscope were recorded as well.Results The measurement of ablation zone with naked eyes showed with the ablation zone expanded with time in 80 W-power cases,but the pace of expansion slowed down,but in 120 W-power cases,expansion of the ablation zone was not obvious; the ablation zone in 120 W-power was bigger than that in 80 W-power at 5 min,their difference decreased with time,and the ablation zones were similar at 10 min.The cluster needle can produce ablation zone with lesser aspect ratio than that of single electrode needle,consequently similar to circle.Ultrasonic measurement of the ablation zone had real discrepancy.Most of longitudinal diameters were greater than the real ones,while in large ablation lesions,vertical diameters were often less than the real ones.Under optical microscope,no change could be found in shape and structure of the cells in ablation zone.Conclusion The output power and performing time have impact on ablation.The high-power output increased heat production as well as reduction of heat conduction.Compared with single electrode needle,the cluster needle produced ablation zone closer to real hepatic tumor,thus has more reliable effect to small hepatocellular carcinoma with diameter around 2 cm.The ultrasond has a great significance in RFA guidance,but it could not accurately define the border of ablation zone.

Objective To explore the reliability of assessing the renal damage and prognosis with enhance-lfow (E-Flow) in patients with systemic lupus erythematosus (SLE) by detecting hemodynamics indexes of intrarenal arteries. Methods There were 50 SLE patients who were treated in the Second Hospital Afifliated to Harbin Medical University from May 2012 to March 2013. The 50 SLE patients were divided into 2 groups:28 patients with LN and 22 ones without LN, and 30 healthy persons were served as the control group who were from the health check centre. All patients underwent renal ultrasonic examination, and two-dimensional images were observed. E-Flow technique were used to measure the peak systolic velocity (PSV), end-diastolic velocity (EDV) and vascular resistance indexes (RI) of the segmental, interlobar, arcuate and interlobular arteries. ANOV was used to compare the PSV, EDV and RI of segmental, interlobar, arcuate and interlobular arteries in the three groups, and LSD-t was used to compare the indexes between the two groups. A linear correlation analysis was used to determine the correlation between the RI of the intrarenal arteries in patients with LN and the levels of serum creatinine. Results The two-dimensional images of kidneys in patients without LN were normal. There were 8 cases with renal parenchymal diffused change in patients with LN. The spectrums of interlobular arteries in patients without LN were similar with those of control subjects, and the turgor curve of diastolic phase reduced slightly. The spectrums of interlobular arteries in patients with LN were blunt, with high resistance and hypoperfusion. Compared with the control subjects, PSV of the interlobar, arcuate and interlobular arteries in patients with LN decreased statistically (t=-2.46,-2.40,-3.49, P<0.05 or 0.01). EDV of the intrarenal arteries in patients with or without LN decreased statistically (patients with LN:t=-5.50,-5.95,-5.83,-5.01, all P<0.01;patients without LN:t=-3.41,-3.69,-3.29,-2.49, P<0.05 or 0.01). Compared with patients without LN, PSV and EDV of the arcuate and interlobular arteries in patients with LN all decreased statistically (PSV:t=-2.00,-2.16, both P<0.05;EDV:t=-2.13,-2.16, both P<0.05). Compared with the control subjects, RI of the intrarenal arteries in all SLE patients increased signiifcantly (patients with LN:t=12.78, 13.30, 11.95, 9.52, all P<0.01;patients without LN:t=9.88, 10.05, 8.71, 5.30, all P<0.01). Compared with patients without LN, RI of the the intrarenal arteries in patients with LN increased signiifcantly (t=2.05, 2.38, 2.43, 3.57, P<0.05 or 0.01). There were positive correlations between the RI of the intrarenal arteries in patients with LN and the level of serum creatinine (r=0.684, 0.752, 0.755, 0.851, all P<0.01). Conclusions E-Flow could clearly display the branches of intrarenal arteries and assess the progress and prognosis of the patients with SLE by measuring intrarenal arteries hemodynamics.

Hyperlipidemia is a major factor causing coronary heart disease and atherosclerosis. The high-density lipoprotein cholesterol (HDL-C) is a major indicator for measuring lipid levels. However, there is no an effective medicine that can obviously increase HDL-C at present. According to previous laboratory studies, atractylodes macrocephalae extracts could significantly increase HDL-C level. In this study, the metabolic hyperlipidemia rat model was established by feeding high-sugar and fat diets and alcohol-drinking to explore the effect and mechanism of atractylodes macrocephalae extracts on hyperlipidemia rats. According to the findingins, different doses of atractylodes macrocephalae extracts could reduce the levels of TC, TG, LDL-C, ACAT and increase the contents of LCAT, HDL-C. Particularly, the atractylodes macrocephalae extracts (100 mg · kg(-1) group showed increase in HDL-C by about 50% and significant declines in HMG-CoA reductase, TC, TG. In conclusion, Atractylodes Macrocephelae Rhizoma extracts could effectively regulate the dyslipidemia of hyperlipidemia rats, especially on HDL-C. Its mechanism may be related to reduction in cholesterol synthesis by inhibiting HMG-CoA reductase in livers and increase in lipid metabolism and transport by regulating LCAT and ACAT levels.
