Objective To analyse subtyping of iscbemic stroke by the criteria of Trial of Org 10 172 in Acute Stroke Treatment (TOAST), its distribution, and relationship between TOAST subtypes, its risk factors and recurrence. Methods Clinical data of 441 patients of ischemic stroke were collected prospectively during October 1, 2006 to September 30, 2007. All the patients were classified by TOAST criteria into five major subtypes and followed-up for one year since its first episode. Dates of its recurrence and death due to recurrence were recorded. Results All the 441 patients with ischemic stroke could be subtyped etiologically according to TOAST criteria as follows: etiology undetermined in 42.3 percent, small-vessel occlusion in 30.9 percent, large-artery atherosclerosis in 17.3 percent, cardioembolism in 9.3 percent, and others in 0.2 percent, without statistically significant difference in its gender and age distributions. Recurrence rate of iscbemic stroke in one year since its first episode for varied subtypes was 33.3 percent for cardioembolism, 14. 6 percent for etiology undetermined, 13.7 percent for large-artery atherosclerosis and 6.9 percent for small-vessel occlusion, respectively. There was no significant difference in risk factors for varied subtypes of iscbemic stroke, including history of smoking, hypertension, diabetes, cardiac disease, and serum levels of total cholesterol, low-density lipoprotein cholesterol, fihrinogen and glucose. Conclusions Varied subtypes of iscbemic stroke had different risk factors and recurrence rate by TOAST criteria, which can be used as an etiologic classification for its secondary prevention.

Objective To observe the effect of parecoxib united with local anaesthesia analgesia system on analgesia after radical resection of liver cancer. Methods Ninety patients undergoing elective radical resection of liver cancer were randomly assigned to three groups, with 30 patients in each group. The patients in parecoxib group (P group) received parecoxib 40 mg through vein before the end of operation for 30 min, and were injected parecoxib 40 mg at 12 h, 24 h and 46 h after operation. The patients in local anethsia analgesia system group (L group) received embedding hypodermic pervasion canal in incision subcutaneously, then connected the pump with 0.25% ropivacaine 250 ml, with infusion speed of 4 ml/h.The patients in united group(U group)receiced the same methods with those in P group and L group. When the patients'visual analogue scale (VAS) scores were higher than 5 scores, they were given muscle injection of pethidine 50 mg. The VAS scores and Ramsay sedation scores at the time of tracheal extubation (T0), postoperative 2 h(T1), 6 h(T2), 12 h(T3), 24 h(T4) and 48 h(T5), the adverse reaction rate, dosage of pethidine, and analgesia satisfaction were compared. Results The resting and movement of VAS scores and Ramsay sedation scores at each time in P group and L group had no significant difference (P>0.05). The resting and movement of VAS scores and Ramsay sedation scores at each time in U group were significantly better than those in P group and L group (P<0.05). The rate of nausea and vomiting in three groups had no significant difference among three groups (P > 0.05). The rate of drowsiness in U group was significantly lower than that in P group and L group:6.67%(2/30) vs. 26.67%(8/30) and 23.33%(7/30), P < 0.05. The analgesia satisfaction in U group was significantly higher than that in P group and L group:93.33%(28/30) vs. 56.67%(17/30) and 53.33%(16/30), P<0.05. Conclusions The analgesia effect of the parecoxib united with local anaesthesia analgesia system for radical resection of liver cancer is perfect.

Objective:To investigate the effect of Xanthium mongolicum Kitag. ethanol extract (EXM) on airway inflammation induced by house dust mite (HDM) in mice with allergic asthma, and to explore the possible mechanism. Methods:The mice were randomly divided into blank group, model group, positive control group and low, medium and high dose groups, with 6 mice in each group. The low, medium and high dose groups were intragastrically administered with 100, 200 and 400 mg/kg of EXM, and the positive control group was given 1.56 mg/kg salbutamol solution. Mice in the blank group and the model group were intragastrically administered with equal volume of solvent, once a day for 8 consecutive days. Except the blank group, the other groups were sensitized with HDM on the 3rd, 4th and 5th days after administration to establish asthma models. After administration, the number of eosinophils (EOS), total cells and various kinds of cells (neutrophils, macrophages, lymphocytes and EOS) in bronchial irrigation fluid (BALF) of mice were observed. The levels of serum IgE and inflammatory factors (IL-4, IL-5, IL-10 and IL-13) in BALF and lung tissue were measured by enzyme-linked immunosorbent assay (ELISA). Pathological and inflammatory changes of bronchial smooth muscle in mice were observed by HE and PAS.Results:Compared with the model group, the number of EOS significantly decreased ( P<0.01 or P<0.05), the total cells count, macrophages, neutrophils, lymphocytes and EOS in BALF significantly decreased ( P<0.01), the content of IL-4 (142.59 ± 16.51 ng/L, 70.47 ± 20.63 ng/L vs. 212.18 ± 58.51 ng/L), IL-5 (57.49 ± 5.49 ng/L, 47.47 ± 6.30 ng/L vs. 72.65 ± 19.11 ng/L), IL-10 (98.51 ± 18.31 ng/L, 71.85 ± 9.15 ng/L vs. 120.16 ± 23.35 ng/L), IL-13 (85.81 ± 23.66 ng/L, 39.99 ± 17.37 ng/L vs. 149.07 ± 33.19 ng/L) in BALF significantly decreased ( P<0.05), and the content of IL-4 (154.55 ± 25.70 ng/L, 143.30 ± 22.19 ng/L vs. 214.68 ± 31.95 ng/L), IL-5 (87.49 ± 5.95 ng/L, 61.84 ± 8.14 ng/L vs. 97.65 ± 12.10 ng/L), IL-10 (91.28 ± 18.69 ng/L, 62.04 ± 9.39 ng/L vs. 117.80 ± 20.72 ng/L), IL-13 (196.48 ± 15.90 ng/L, 132.02 ± 6.86 ng/L vs. 238.42 ± 28.41 ng/L) in lung homogenate significantly decreased ( P<0.05), the serum IgE level in the high dose group significantly increased ( P<0.05). Conclusion:The Xanthium mongolicum Kitag. can inhibit allergic asthma induced by HDM, which may be through inhibiting the secretion of inflammatory cytokines by pulmonary macrophages.

Objective To assess the feasibility of applying intensity-modulated radiotherapy(IMRT)simultaneous integrated boost(SIB)to replace conventional radiotherapy(CR)plus brachytherapy of whole pelvis in locally advanced cervical eaneer(LACC).Methods Five LACC patients based difference position of uterus were chosen and worked out CR and IMRT SIB plans respectively.Dose distributions were compared between IMRT SIB and CR.Results When uterus was in ante-,neutral-,retro-pnsition and deviation respectively,IMRT SIB could provide enough and homogeneous dose distribution for target volume and reduce irradiated volumes and doses for organs at risk(recta,bladder and small intestine)than CR.The doses of the A,B,and fundus of uterus were higher in IMRT SIB than CR.However,in ease of small intestine was close to or encircled the uterus,the targets volume dose would be inadequacy.Conclusions LACC IMRT SIB's dose distribution is better than CR(except excess ante-position)and may help to treat those patients who couldn't be suitable with brachytherapy.

Objective To assess the clinical efficacy of levonorgestrel-releasing intrauterine system(LNG-IUS) in the treatment of adenomyosis. Methods Forty-two patients with adenomyosis diagnosed by clinical symptoms, MRI, laparoscopy and/or chromatic colour type-B ultrasound were treated with LNG-IUS, and the menstrual blood volume, severity of dysmenorrhea and uterine volume were observed three months later. Results After 3 month treatment of LNG-IUS, the menstrual blood volume reduced significantly to (27?11)% of that before treatment. The uterine volume was decreased from (143?33) cm 3 to (115?22) cm 3( P
