Objective　To measure the levels of urokinase-type plasminogen activator (uPA) and its receptor (uPAR) in synovial fluid and plasma of patients with RA and investigate its clinical significance.Methods　By using ELISA sandwich method,the levels of uPA and uPAR in plasma from 46 patients with RA and 8 with osteoarthritis (OA) were measured.Those in synovial fluid (SF) from 14 patients with RA,and plasma from 12 healthy subjects were measured as controls.Results　The concentration of uPA and uPAR in SF from patients was significant higher than that in their plasma (P＜0.001,P＜0.01),and the concentration of uPA and uPAR in plasma of RA was also much higher than that in plasma of OA patients (P＜0.05,P＜0.000 1) and healthy subjects (P＜0.000 1,P＜0.001).There was no significance between plasma levels of RF＋ and RF－ in RA patients.The concentration of uPA and uPAR of plasma in RA correlated positively with CRP,RF and the number of swelling joints.Conclusion　The levels of uPA and uPAR in SF and plasma are useful parameters for monitoring disease activity of RA.These findings suggest that the uPA and uPAR genes may play an important role via proteolytic damage of the extracellular matrix during the development of RA.

Objective To investigate the role of chemokine in inducing peripheral arthritis in spondyloarthropathy(SpA).Methods Microarray was used to screen the candidates of inducing peripheral arthritis in SpA,and enzyme linked immunosorbent assay(ELISA)was used to verify the results.Peripheral blood mononuclear cells(PBMC)from 5 healthy subjects were co-incubated 1.5 hours with synovial fluid of 5 patients with SpA,total RNA were then extracted,and the samples were screened for the target genes by using superarray techniques.ELISA was used to determine CXCL1 protein levels of 54 ankylosing spondylitis(AS)patients and 30 healthy controls,also to determine the CXCL1 levels of synovial fluids from 33 SpA patients and 14 osteoarthritis(OA)patients,and to determine CXCL1 protein levels by ELISA before and after treatment with infliximab.Results The expression of CXCL1,CXCL2,CXCL3 and IL-8 were more than 2 fold higher after stimulated by synovial fluids.However,there was no change in other chemokines and cytokines,such as TNF?,IL-6 and IL-1 after stimulation.The protein level of CXCL1 was significant higher in serum of patients with AS than that of healthy control(P

Objective To compare the clinical efficacy of multi-target lateral puncture combined with intracranial pressure monitoring in treatment of basal ganglia hypertensive cerebral hemorrhage. Methods Sixty-six patients of basal ganglia hypertensive cerebral hemorrhage, with bleeding volume over 40 ml were divided into experimental group (36 cases) and control group (30 cases) by random digits table method. Patients in experimental group underwent multi-target puncture combined with routine intracerebroventricular treatment of intracranial pressure monitoring,and patients in control group underwent frontotemporal craniotomy and small hematoma decompressive craniotomy. The operation time, length of stay, hematoma evacuation rate, catheter drainage time, total amount of mannitol, Glasgow Coma Scale (GCS) scores 3 days after treatment, complication rate and 3-month Glasgow Outcome Scale (GOS) scores were recorded and compared between two groups. Results The operation time, length of stay, hematoma evacuation rate 1 day after treatment, and total amount of mannitol in experimental group were significantly lower than those in control group: (67.5±8.0) min vs. (109.3±9.6) min, (18.6±4.2) min vs. (23.3±5.9) min, (59.7±9.2)% vs. (80.4±11.6)%, (668.6±83.5) g vs. (1 430.4±107.1) g, P<0.01. The hematoma evacuation rate 3 days after treatment, catheter drainage time and GCS scores 3 days after treatment between two groups had no significant differences (P>0.05). The GOS scores in experimental group: 5 points (9 cases), 4 points (10 cases), 3 points (8 cases), 2 points(5 cases), and 1 point(4 cases). The GOS scores in control group: 5 points (4 cases), 4 points (4 cases), 3 points (7 cases), 2 points (9 cases), and 1 point (6 cases). Long curative effect in experimental group was better than that in control group (Z =2.318, P =0.020). The incidence of intracranial air in experimental group was significantly higher than that in control group: 27.8%(10/36) vs. 3.3%(1/30), P<0.05. Other complications had no significant differences between two groups (P>0.05). Conclusions Multi-target lateral puncture combined with intracranial pressure monitoring in treatment of basal ganglia hypertensive cerebral hemorrhage has more advantages, including less trauma, wide surgical indications, short operation time and hospital stay, less postoperative mannitol, and decreased mortality rate. For older, patients with organ dysfunction, and patients who can not tolerate craniotomy, it is an effective treatment, and worthy of promotion.

Objective To evaluate the clinical effect of acupotomy therapy combined with acupuncture based on distal points selection for lumbar intervertebral disc protrusion ( LIDP) . Methods Sixty-eight LIDP patients were randomly divided into treatment group (N=33) and control group(N=35). The treatment group were given acupotomy therapy on the proximal positive response points in the lumbosacral region for relaxing the tendons,and acupuncture therapy based on distal points selection of Shugu, the Shu-stream point of the foot Taiyang bladder meridian, Zulinqi and Weizhong, the shu-stream point and the blood xi-cleft point of the foot Shaoyang gallbladder meridian respectively, twice a week, 2 weeks constituting one course of treatment. The control group was given conventional electroacupuncture therapy on Huatuo clip points, Dachangshu point, bilateral Shenshu points, Yinmen point, bilateral Zibian points and bilateral Yanglingquan points, and together with TDP radiation therapy, 5 times a week, 2 weeks constituting one course of treatment. The two groups received follow-up for one month. The low back pain scores of Japanese orthopaedic society ( JOA) and visual analog scores ( VAS) of pain were used for the evaluation of therapeutic effect after the treatment. Results ( 1) After treatment, the JOA scores were increased and VAS scores were decreased in both groups compared with those before treatment ( P< 0.05) , and the increase of JOA scores and the decrease of VAS in the treatment group were superior to those in the control group ( P< 0.05) . There was statistically significant difference of VAS scores between the two groups ( P < 0.05) during the follow-up period. ( 2) The total effective rate was 87.9%in the treatment group, and was 77.1%in the control group, the difference being significant (P<0.05) . Conclusion The acupotomy therapy combined with acupuncture based on distal points selection is effective and safe for lumbar intervertebral disc protrusion, which has the advantages of reliable long-term effect and low recurrence rate, showing good prospects for extensive clinical application.

OBJECTIVE To compare the effect and safety of coblation plasma surgery and beclomethasone dipropionate nasal spray in the treatment of perennial allergic rhinitis. METHODS A stratified,randomized,controlled trial of surgery and medicament was performed in the treatment of perennial allergic rhinitis. A total number of 102 patients were involved in the trial,including 56 cases with swelling of inferior turbinate,28 cases in surgery group,28 cases in medicament group; and 46 cases without swelling of inferior turbinate,23 cases in surgery group,23 cases in medicament group. Coblation plasma surgery was performed in all surgery groups. Each patient was given 50?4?2 ?g/d of beclomethasone dipropionate nasal spray in all medicament groups,Treatment time was 3 months. The symptom scores (SS)and visual analogue scale(VAS)were recorded. RESULTS Effect assessment showed that both methods had significant repressive effect on allergic symptoms,the effect of surgery group was better than that of medicament group at the 14th day,28th day and 3th month in cases with swelling of inferior turbinate. Difference between the surgery group and medicament group in cases without swelling of inferior turbinate had no statistic significance. CONCLUSION Both coblation plasma surgery and beclomethasone dipropionate nasal spray are effective to treat perennial allergic rhinitis. But coblation plasma surgery is better than medicament in cases with swelling of inferior turbinate.

To study the etiology and treatment of relapsing polychondritis, especially tracheostenosis, 3 patients with severe relapsing polychondritis complicated with severe tracheostenosis were presented. The clinical features, criteria of diagnosis, etiology, therapy and prognosis were discussed. All the 3 cases were female. They were misdiagnosed as laryngopharyngeal inflammation with severe tracheostenosis, so that their correct diagnosis and treatment were delayed. The report and discussion of such cases are helpful to its early diagnosis and improve ment of their prognosis.

Aim To observe the effect of polydatin(PD) on the activities of ?-AR in cardiomyocytes under the stimulation of LPS. Methods Cardiac myocytes were isolated and cultured from neonatal rats. Radioligand binding assay and flow cytometry were used to detect the function of ?-AR. Results In control group, the density of ?-AR (B max) was 4.14?1.41 fmol?(1?105 cells) -1 and ?-AR affinity (K d) was (4.02?0.59) nmol?L -1. In LPS group, ?-AR density was down-regulated 〔B max=1.78?0.12 fmol?(1?105 cells) -1〕 and the affinity decreased (K d=23.88?2.34 nmol?L -1). In LPS+PD group, ?-AR B max was recovered to 3.37?0.36 fmol?(1?105 cells) -1 and the affinity increased (K d=3.44?0.44 nmol?L -1). In PD group, ?-AR functions had no significant difference with normal group 〔B max=2.76?0.32 fmol?(1?105 cells) -1 and K d=4.63?1.54 nmol?L -1〕. The ?-AR amount measured by flow cytometry showed the same change tendency as the radioligand binding assay. Conclusion ?-AR activities may be down-regulated during the pathological process of LPS treatment. PD could reverse the effects of LPS by up-regulating ?-adrenoreceptors.

5) who were conscious and had no obvious cardio-respiratory and hepato-renal dysfunction were enrolled in this study. The patients received intravenous PCA with morphine for the first 48 hours. The PCIA morphine solution contained morphine 2-6mg?ml-1 and droperidol 1-2 mg?30 ml-1 . PCIA included a bolus dose of morphine 1-3 mg with a 5 min lockout. No background infusion was given. Morphine PCIA was then combined with transdermal fentanyl. The initial dose of transdermal fentanyl was 25?g ? h-1 in the first two to three days. The dose was then gradually increased in 25 ?g?h-1 increments according to VAS scores and the amount of Ⅳ morphine needed to reduce the persistent pain until transdermal fentanyl alone could provide sufficient relief of persistent pain and Ⅳ morphine was given only for breakthrough pain. Pain intensity (VAS scores) before and after treatment, daily consumption of morphine (mg?d-1) and transdermal fentanyl (?g?h-1), vital signs and side effects were recorded.Results The 13 patients included 6 males and 7 females. Their mean (?SD) age was 54?15 yrs and body weight 53? 8 kg. There was positive correlation between the titrated dose of transdermal fentanyl (??k-1) and the initial need of Ⅳ morphine (mg?day-1). Y= 1.3606 X + 6.5088. Persistent pain intensity and breakthrough pain intensity evaluated by VAS scores were significantly reduced during the treatment ( P
