Objectives: To study the difference of Plasminogen Activation System in patients with coronary heart disease by different behavior types. Methods: 81 patients with coronary heart disease and 59 normal control were evaluated by Type A Behavior Scale. t-PA and PAI-1 activities of both groups were also measured. Results: The activity of PAI-1 was higher and t-PA was lower in patients with coronary heart disease, and this difference is also found between Type A and Non Type A patients. Conclusion: The activity of t-PA is decreased and PAI-1 increased in patients with CHD, this phenomenon are also related to Type A Behavior traits.

Objective To observe the intervention effect of Wuxing-Jiangu exercise for different syndrome types of elderly patients with chronic low back pain.Methods A total of 199 patients who met the criteria of chronic low back pain (CLBP) were divided into a Wuxing-Jiangu exercise group (86 cases), a control group (85 cases) and a health education group (28 cases). On the basis of health education, theWuxing-Jiangu exercise group was given Wuxing-Jiangu exercise; the control group was treated with the warm type frequency therapeutic instrument; health education group was only given health education guide. The changes of the score of CLBP patients before and after treatment with different syndrome types were observed.Results After 3 months of treatment, the score of the kidney deficiency syndrome and spleen deficiency syndrome in the Wuxing-Jiangu exercise group, the control group and the health education group had significant differences (H were12.554, 8.014, respectively;all P<0.01); After 3 months of treatment, the score of kidney deficiency syndrome and spleen deficiency syndrome in the Wuxing-Jiangu exercise group reduced than before the treatment (Z were -5.975,-5.025, respectively)and 1 month after the treatment(Z were -5.976,-5.026, respectively) (all P<0.01).Conclusion Wuxing-Jiangu exercise can reduce the score of the kidney deficiency syndrome and spleen deficiency syndrome and improve clinical syndrome.

0.05).3.Thirty-three point three percent of animals from parental strain group were found fibrillations potentials and the po-sitive sharp waves in gastrocnemius electromyogram,no obvious abnormal waves were found in animals from both waaF mutant and control group.Conclusions The ganglioside-like epitope in LOS of CJ is critical antigen in inducing GM1-IgG antibody and in inducing conduction block of peripheral nerve,therefore,provide a support for the molecular mimicry theory as a pathogenesis in the axonal GBS following CJ infection.

Methods Forty‐one cases of healthy volunteers ,including 23 cases of male ,18 cases of female ,aged 7 -73 .Patients were divided into 4 groups:7- <15 age group (n=11) ,15- <35 age group (n=10) ,35- <45 age group (n=9) ,≥45 age group (n=11) .We used the application of Toshiba 1 .5 T MRI head coil ,MRI sequence of time‐SLIP marked CSF to calculated the peak velocity of CSF in the midbrain aqueduct and measure the diameter and length of the midbrain aqueduct .Results The peak flow velocity be‐tween the 7- <15 age group and 15 - <35 age group ,35 - <45 age group ,≥45 age group were statistically significant (P<0 .05);inner diameter and length were no statistically significant difference (P>0 .05) between age .Conclusion In the midbrain aqueduct ,CSF is two‐way flow and supports the CSF of the pulsatile flow theory ;MRI sequence of time‐SLIP could measure CSF velocity and display the turbulence fluiding .

OBJECTIVETo assess the feasibility and safety of robot-assisted laparoscopic radical prostatectomy (RLRP) in the treatment of prostate cancer.

METHODSUsing the da Vinci robot surgical system, we performed RLRP for 34 patients with localized prostate cancer and analyzed the intraoperative and follow-up data.

RESULTSThe procedures were performed successfully in all the patients, with the mean operation time of 198 min (range 135-340 min), average blood loss of 257 ml (range 50-700 ml), and 1 case of blood transfusion, but no postoperative complications. Three cases had positive surgical margins. Postoperative examination at 4 weeks showed PSA > 0.2 microg/L in 2 cases, suggestive of residual tumor, for which maximal androgen block therapy was administered. The other 32 patients were followed up for 3-10 (mean 7.5) months, during which the average level of serum tPSA remained < 0.2 microg/L. Urinary continence was found in 94% (32/34) and 97% (33/34) of the patients at 3 and 6 months, respectively, of whom 77% (26/34) and 88% (30/34) had no urinary leakage (0 pad per day).

CONCLUSIONRLRP, with its advantages of less perioperative blood loss, low rate of positive margin, and good urinary continence, is a safe and effective surgical option for the treatment of prostate cancer.

Brainstem infarction accounts for about 9% to 21.9% of all cerebral infarctions. This article reviews the etiology of brainstem infarction and its pathogenesis,clinical manifestation,diagnosis,and treatment.

Objectives To investigate the prevalance of quinolone resistance in Laribacter hongkongensis and to evaluate the influence of agar dilution and disc diffusion methods on susceptibility testing for the bacterium. Methods Susceptibility to quinolones of L.hongkongensis was tested by agar dilution and disc diffusion methods. The results for both methods were compared. Results L.hongkongensis isolates exhibited different susceptibility rate for quinolones (levofloxacin>ciprofloxacin>norfloxacin>nalidixic acid). All of the fish isolates were susceptible to levofloxacin and more than 90%were susceptible to ciprofloxacin and Norfloxacin. However,by agar dilution, only 62.50%, 37.50%,48.21%, 19.64%of the frogs isolates were susceptible to levofloxacin, norfloxacin, ciprofloxacin, nalidixic acid, respectively. For fish isolates, comparision of susceptibilities between agar dilution and disc diffusion showed a high (> 95%) percentage agreement for levofloxacin and ciprofloxacin and the highest crepancies were observed with norfloxacin (100%) .But it showed a high discrepancy when comparing the two methods for frogs isolates. Conclusions The resistance rate of L. hongkongens to quinolones was high , especially for frog isolates. The results suggested the use of agar dilution on susceptibility testing for quinolones in L. hongkongensis.

BACKGROUND:It has found that secretions of tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β) and interleukin 6 (IL-6) are closely related to osteoporosis
OBJECTIVE:To further investigate the levels of TNF-α, IL-1β and IL-6 of bone tissue in ovariectomized rats and their relationship with osteoporosis.
METHODS: Sixty 3-month-old female Sprague-Dawley rats were randomly divided into control group and test group (n=30 per group). In the test group osteoporosis model was induced by ovariectomy folowed by intraperitoneal injection of aluminum nitride solution; while rats in the control group were given intraperitoneal injection of normal saline without ovariectomy. The experiment cycle was 12 weeks. One week after modeling, serum level of estradiol was tested, and the bone mineral density of rats measured with bone densitometry. In the meanwhile, the levels of TNF-α, IL-1β and IL-6 in bone tissue were detected to analyze the correlation between cytokines and bone mineral density.
RESULTS AND CONCLUSION: The level of serum estradiol in the test group was significantly lower than that in the control group (P=0.007); the bone mineral density of the lumbar spine and femur in the test group was significantly lower than that in the control group (P=0.006, 0.004). Compared with the control group, the percentages of trabecular bone and osteoblast area within the visual field in the test group were significantly lower, while the osteoclast area within the visual field was significantly higher (P=0.037, 0.029, 0.044). Compared with the control group, the levels of TNF-α, IL-1β and IL-6 in the test group significantly increased (P=0.032, 0.031, 0.025). And the bone mineral density of the lumbar spine and femur was negatively correlated with the levels of TNF-α, IL-1β and IL-6 in the test group (P < 0.05). In conclusion, the osteoclast activity is enhanced by elevating the levels of TNF-α, IL-1β and IL-6 of bone tissue of ovariectomized rats, and increasing the percentage of osteoclast area within the visual field. Moreover, the percentages of trabecular bone and osteoblast area within the visual field have a decline, which accelerates the process of bone resorption and leads to the formation of osteoporosis.
