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

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.

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 study the synthesizing site,transporting mode,and storing position of essential oil in Pogostemon cablin stems and leaves.Methods Ultrathin slicing and histochemical methods were used.Results In parenchyma cells in the stem of P.cablin,dark osmiophilic material was observed in plastids and mitochondria,otherwise,some small gray vesicles were also found in cytoplasm.Some dark osmiophilic droplets were found to adhere to outer membrane of small gray vesicles,and many small gray vesicles with osmiophilic droplets gathered in outer membrane of large vacuole.In leaves,it was different case.Because palisade tissue cells were arranged closely,which had smaller volume and rich chloroplasts,so there was not large vacuole in palisade tissue cells.Plastids,mitochondria,and small vacuole were distributed in high density,but the first two organelles contained more dark osmilphilic substance than latter.Conclusion The plastid is the main synthesis site of essential oil,and the essential oil was mainly transferred by small gray vesicles into large vacuole to store in the stem.In leaves,chloroplast not only has photosynthesis,but also is the main synthesis site of essential oil,and essential oil is permeated into small vacuole to store.

Aim To investigate the effects of TSG on the content of nitric oxide and the expression of endo-thelium nitric oxide synthase in artery vessels of experimental atherosclerotic rats.Methods Sixty male rats were randomly divided into six groups.GroupⅠ,Normal control;GroupⅡ,Model control;Group Ⅲ,TSG low dose;Group Ⅳ,TSG middle dose;GroupⅤ,TSG high dose;group Ⅵ,Simvastatin.After 12 weeks,blood samples were collected from carotid arteries of rats,and the levels of NO in serum were measured.After that,the aortas were separated from the bodies and placed in-70℃,then the content of nitric oxide synthase was detected,and gene expression of eNOS and iNOSmRNA in artery vessels were respectively measured with RT-PCR method.STATA 8.0 software was adopted in date analysis..Results compared with those of the model group,the level of NO,the activity of NOS and the gene expression of eNOS were increased,and the gene expression of iNOS was reduced by simvastatin and TSG 30,60,120 mg?kg-1?d-1 in the high cholesterol-fed rats,which showed a dose-dependent effect.Conclusion TSG can enhance the expression of eNOS gene and reduce the expression of iNOS gene in aorta vessels of experimental atherosclerotic rats,which may be one of the anti-atherosclerosis mechanisms of TSG.

Objective To investigate the effect of H 2 S and its synthetase inhibitor propargylglycine ( PAG) on the autophagic function in caerulein-induced acute pancreatitis ( AP) mice.Methods A total of 60 male BALB/c mice were randomly divided into control , AP, NaHS and PAG group using random number method.AP was induced in mice via hourly intraperitoneal injection of caerulein (50 μg/kg) continuously for 6 hours.NaHS and PAG group received NaHS (10 mg/kg) or PAG (50 mg/kg) 1 h before the AP induction . A equal volume of normal saline solution was injected in control group and AP group .All the mice were killed at 12 h after the first caerulein injection and blood sample was collected for the detection of serum amylase and lipase content.Deproteinization spectrometry was used to detect serum H 2 S content, and pancreatic tissue was pathological examined and scored . Real-time PCR detected mRNA expression of CSE , and the protein expression of LC3-Ⅱ/LC3 Ⅰand p62 was measured using Western blot .Results Serum amylase, lipase, H2S, CSE mRNA, LC3Ⅱ/LC3Ⅰand p62 were (2 700 ±100)U/L, (70 ±20)U/L,(22.9 ±1.7)mmol/L, 1.0 ±0.1,0.419 ±0.080, 0.227 ±0.140 in control group; (17 290 ±500)U/L,(520 ±40)U/L, (31.3 ± 3.0)mmol/L, 5.4 ±0.4, 1.184 ±0.120, 1.985 ±0.210 in AP group; (27 784 ±1 200)U/L, (900 ± 80)U/L,(38.6 ±3.3)mmol/L, 6.9 ±0.9,1.600 ±0.210, 4.229 ±0.050 in NaHS group; (13 750 ± 2 000)U/L,(370 ±20)U/L, (24.5 ±2.1)mmol/L, 4.2 ±0.5, 0.745 ±0.130, 1.203 ±0.080 in PAG group.All those biomarkers detected above in AP group significantly increased compared with control group , which were much lower than those in NaHS group , but higher than those in PAG group , and the differences were statistically significant (all P<0.05).Pancreatic histological damage in NaHS group was more severe than that in AP group , which in PAG group was less severe than that in AP group .Conclusions PAG could greatly decrease serum amylase and lipase level , and reduce the damage on autophagy and the severity of AP .

Objective To compare the effects and complications of lumboperitoneal shunt ( LP ) and ventriculoperitoneal shunt ( VP ) in the treatment of post?traumatic hydrocephalus. Methods Eighty patients with post?traumatic hydrocephalus treated in the neurosurgery department of Zhangjiagang Hospital of Traditional Chinese Medicine from March 2014 to March 2010 were retrospectively analyzed. The patients were randomly divided into two groups,40 patients treated with LP were assigned into the LP group and 40 patients undergone VP treatment were seen as the VP group. All patients were followed up for 1 year to investigate and compare the symptom improvement rate,neurological deficit score and the incidence of complication of the two groups. Results The total effective rate of hydrocephalus disappearance in the LP group was 41. 50% ( 37/40) and 87. 50%( 35/40) in the VP group. The difference between the two groups was not statistically significant (χ2=0. 556,P=0. 456);the neurological deficit scores before treatment in the LP group and VP group were (28. 35±8. 64) points and (29. 13±7. 98) points,there was no significant difference between the two groups (t=0. 419,P=0. 676) . The difference in the scores of neurological deficit after treatment in the LP and VP group was not statistically significant ( (19. 32±5. 34) points vs. (21. 62±4. 86) points,t=1. 480,P=0. 143),the average scores of neurological deficits in the two groups were significantly better than those before treatment ( t=5. 623, 5. 084,P<0. 001 ) . There was no significant difference in the average score of improvement of urinary incontinence between the two groups before and after treatment ( t=0. 376,1. 265,P>0. 05) ,the average score of urinary incontinence improvement after treatment in both groups were better than those before treatment ( t=4. 891,5. 370,P<0. 001) . In the LP group,the incidence of bleeding,infection,shunt related complications and shunt abnormality were all 2. 50% ( 1/40 ) , the overall complication rate was 10. 00%, the incidence of bleeding,infection,shunt related complications and shunt abnormality in the VP group were 7. 50% (3/40), 10% ( 4/40 ) , 5% ( 2/40 ) 10%, ( 4/40 ) , the overall complication rate was 32. 50%, there was significant difference between the two groups (χ2=6. 050,P=0. 014) . Conclusion LP and VP have significant curative effect on the treatment of post?traumatic hydrocephalus,but the overall incidence of LP complication after 1 year is significantly lower than that of VP,and is worth popularizing widely in clinical practice

AIM: To investigate the preventive effect of tetrahydroxystilbene-glucoside (TSG) on experimental atherosclerosis rats. METHODS: Sixty one male rats were randomly divided into six groups. normal control; model control; TSG low dose(30 mg?kg-1?d-1);TSG middle dose(60 mg?kg-1?d-1);TSG high dose(120 mg?kg-1?d-1); simvastatin(2 mg?kg-1?d-1). The AS model of rats was made by feeding high grease food and injecting VitD3 .All the rats were fed for 12 weeks, blood samples were drawn from carotid artery of rats, the levels of TC, TG, HDL-C, LDL-C ,CRP,IL-6 and TNF-? in serum were measured with biochemical method. After blood samples were collected , the aorta samples were separated from the bodies, then they were placed 4% paraformaldehydea and were through Sudan Ⅳ and HE staining. STATA7.0 software was used to evaluate the differences between groups. RESULTS: Data of the study demonstrated that the levels of TC、TG、LDL-C、TNF-?、IL-6 and CRP were decreased remarkably, the level of HDL-C was increased by TSG 60, 120 mg?kg-1?d-1 group in the high cholesterol-fed rats, which showed a dose-dependent effect. The result of Sudan Ⅳ and HE staining suggested that the lipid deposits in aortic endothelium in TSG group were less than those in model group. CONCLUSION: TSG has preventive effect on the experimental atherosclerosis among the high cholesterol-fed rats. The anti-atherogenic effect of TSG seems to be closely related to regulating plasma lipid profile, and inhibiting inflammation.

Aim To observe the effects of 2,3,4',5-tetrahydroxystilbene-2-O-?-D glucoside on expression of ICAM-1、VCAM-1 and VEGF in atherosclerotic rats,and approach the influence of TSG in atherogenesis.Methods Sixty SD rats were randomly divided into six groups(Control,Model,TSG 30、60、120 mg?kg-1?d-1 and Simvastatin 2 mg?kg-1?d-1 groups),given high-fat-diet for 12 weeks,the level of SOD and MDA then were determined.ICAM-1、VCAM-1 and VEGF protein were determined with Western blot assay,ICAM-1 mRNA and VCAM-1 mRNA were measured with RT-PCR,and VEGF expression was assessed by immunohisto-chemistry.Results In comparison with the model,the level of SOD increased markedly and the level of MDA decreased markedly after administering TSG;TSG could inhibit the expression of ICAM-1、VCAM-1 and VEGF in atherosclerotic arteries.Conclusions TSG could show its antiatherosclerotic effect by anti-oxydation and inhibiting the excretion of adhesion molecules.
