Isokinetic training, as a technique of orthopaedic rehabilitation, is a new and valuable method in evaluation of muscle function and in training muscle strength. It has higher accuracy and reproducibility in evaluation of muscle function. When isokinetic training of muscle strength is done, kinetic velocity is fixed beforehand in the dynamic instrument so that the resistance matches the actual force applied by the individual. The resistance maintains the maximum throughout the range of motion and produces the greatest muscle strength. As a result, the isokinetic muscle strength is effective and safe in the orthopaedic rehabilitation.

To investigate the role of Fas/FasL system in pathogenesis of hemodialysis(HD) and its correlation with clinical status, plasma levels of sFas/sFasL and the expression of Fas antigen on peripheral blood lymphocytes(PBL) membrane were assayed by ELISA and flow cytometry respectively. The CD3 + Fas + of PBL cells was singnificantly higher( P

Objective Study the value of clinical application of BaiJi and absorbable Gelatin in embolizing uterine myoma together with its effecty, side effect and complication.Methods 21 women with uterine myoma undergoing selective uterine arterial embolization by Seldinger's technique were studied. After retrograde transfemoral introduction of a 5 french catheter, the uterine arteries were successively catheterized. Bai Ji and absorbable Gelatin sponge particles were injected through free flow until devasculariztion. Results Uterine myoma's blood supply came from bilaterial uterine arteries demonstrated by angiography. All the supplying artering images disappeared after the embolization. 3～6 months follow up study showed: a marked reduction in the size of myomata by 38%～90%. Clinical symptoms were improved. There was one failure cas and then underwent uterotomy due to infection. Conclusions The short term effect of using Bai Ji and absorbable Gelatin for embolizing uterine myoma is clinically significant, while long term effects is still wating for research.

Objective To study the effect of rosuvastatin(RSVT) on the vascular endothelial function(VEF) ,inflammatory fac‐tors(IF) and prognosis in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention(PCI) .Methods Eighty cases of ACS patients with PCI in our hospital selected from July 2010 to July 2013 were randomly divided into observed group and control group ,40 cases in each group .The observation group were given interference treatment with RSVT while the control group received conventional treatment .The VEF ,IF and prognosis were compared between groups .Results The VWF at 4 weeks after PCI in observation group was lower than that in control group [(92 .6 ± 12 .3)% vs .(105 .4 ± 13 .6)% ,P<0 .05];The ET‐1 at 4 weeks after PCI in observation group was lower than that in control group[(55 .6 ± 5 .6)ng/L vs .(67 .8 ± 7 .4)ng/L ,P<0 .05] .The NO at 4 weeks after PCI in observation group was higher than that of control group[(78 .6 ± 9 .4)μmol/L vs .(63 .2 ± 9 .5)μmol/L ,P<0 .05] .The CRP at 4 weeks after PCI in observation group was lower than that in control group[(5 .4 ± 2 .2) mg/L vs .(10 .5 ± 4 .1)mg/L ,P<0 .05] .The incidence of CVE was 5 .00% (2/40) ,restenosis rate was 2 .50% (1/40) in observa‐tion group ,which was significantly lower than those of the control group [30 .00% (12/40) ,10 .00% (4/40)] ,the differences were statistically significant(P<0 .05) .Conclusion RSVT could effectively improve the VEF and reduce inflammation ,CVE and rest‐enosis rate in patients with ACS after PCI .

OBJECTIVE: To investigate effects of polysulphone membrane filter continuous blood purification (CBP) on decreasing pancreatic amylase and various inflammatory mediators in the treatment of severe acute pancreatitis.METHODS: A total of 47 elderly patients with severe acute pancreatitis, who received CBP therapy was included in the experiment, and the blood routine test, blood biochemistry indexes and blood-gas analysis were performed prior to CBP therapy and continuous for 12 and 24 hours. Meanwhile, APACHE Ⅱ, SAPS Ⅱ and MODS scores were graded by recorded the heart rate, mean arterial pressure (MAP), central venous pressure (CVP), respiratory frequency and body temperature.RESULTS: Compared with pre-treatment, APACHE Ⅱ, SAPS Ⅱ and MODS scores, serum creatinine, hemodiastase, as well as C-reactive protein were decreased after treatment. After treatment, the oxygen index, such as heart rate, MAP, and CVP were declined, and the levels were increased progressively with time prolonged. During the course of CBP, the levels of HCO_3~-, Ga~(2+),and Mg~(2+) were increased than that of pre-treatment. The level of Ga~(2+), Mg~(2+) could maintain in a normal range during CBP therapy, however, it would be decreased when stop treatment.CONCLUSION: The improvement of cardio-pulmonary function relates to interstitial edema of tissue and organs. The effect on removing pancreatic amylase and various inflammatory mediators will be better with time prolonged. It is affirmative to treat elderly patients with severe acute pancreatitis by using CBP therapy.

Objective We established a model of human breast cancer in nude mice, to discuss the feature of pathology and biology of breast cancer,and give help to establish tools of pathogen research. Methods Human breast cancer cells MCF-7 were subcutaneously injected into the right armpit of nude mice to establish human breast cancer models.The mice were divided into composite group, estrogen group, leptin group and the blank group (30 in each). In the composite group,estrogen and leptin were injected into peripheral region of the tumor daily.In the estrogen group,estrogen was injected.In the leptin group, leptin was injected.In the blank group, physiological saline was injected.Tumor growth was observed, and the volume of the tumor was recorded.The tumor tissues obtained from the mice were pathologically examined. Results (1)The tumor-taking rate of leptin group and the blank group were 46.7% (14/30)and33.3% (10/30) ,and the mode is failure.In composite group and estrogen group they were 96.7% (29/30) and 70% (28/30).There was not significant difference between them ( P < 0.05).(2) The differences of average diameter and volume were statistically significant between the composite group and the estrogen group (P < 0.05).(3) Pathology diagnosis was invasive ductal carcinoma. Conclusions (1) Establishing human breast cancer model in nude mice need the stimulation of estrogen. The tumor-taking rate of nude mice has no relationship with leptin.(2) In the study in vivo, leptin as same as estrogen has stimulating effect on MCF-7 cells proliferation.(3) The transplanted cancer cell partly have the pathology and biology features of the human breast cancer cells and give help to establish tools of pathogen research.

Objective To observed the effect of high-intensity focused ultrasound (HIFU) in combination of submicrobubble on ablation of breast tumor VX2 in rabbits.Methods Submicrobubble was prepared,and the appearance,distribution,diameter,and zeta potential were measured.The rabbits were injected with the tumor tissue suspension in bilateral breast tissues.HIFU(150 W,120 W,5 s,3 s) combined with submicrobubble to damage rabbit breast VX2 tumors.The coagulation necrosis was assessed by HE staining.The grayscale changes of the target area before and after HIFU irradiation were recorded automatically by computer.Results The diameter of the submicrobubble was 498.9 nm on average.HE staining showed the area of coagulation necrosis was significantly larger in the HIFU + submicrobubble group than the HIFU + PBS group.The injury range of 150 W irradiation was larger than that of 120 W irradiation,given the same irradiation time.The injury range of 5 s irradiation was larger than that of 3 s irradiation,given the same irradiation strength.The gray scale change in the target area was significantly higher in the HIFU + submicrobubble group than the HIFU + PBS group.Conclusions The submicrobubble exhibited sound imaging performance,and it can be use in the ultrasound therapeutics in the future.
