ObjectiveTo investigate the risk factors related with the prognosis of patients with acute cerebral infarction after intravenous thrombolysis by alteplase in 90 days.MethodsForty patients with acute cerebral infarction treated by intravenous thrombolysis with aheplase were selected and assigned into good outcome group [modified Rankin scale (mRS) 0-1 score] and poor outcome group (mRS 2-6 scores) according to mRS at 90 days.The risk factors were compared between two groups.ResultsPoor outcome group(22 cases) comparing with good outcome group (18 cases),the values of age[ (64.64±11.30) years vs.(58.94±10.47) years ],onset to therapy time(OTT) [(376.73±316.32)min vs.( 176.00±59.74) min],National Institutes of Health stroke scale (NIHSS) score before thrombolysis [ ( 16.73±8.46)scores vs. (11.22±5.20) scores],maximum of systolic blood pressure (SBPmax) in the first 24 hours after thrombolysis[ ( 186.59±24.79 )mm Hg ( 1 mm Hg =0.133 kPa) vs.( 169.00±23.04) mm Hg] and systolic blood pressure variability (SBPV)[(17.11±3.90) mm Hg vs.(13.33±4.97) mm Hg] had significant differences (P＜ 0.05).ConclusionThe values ofage,OTT,NIHSS score before thrombolysis,SBPmax and SBPV in the first 24 hours after thrombolysis are related with the prognosis of patients with acute cerebral infarction after intravenous thrombolysis by altcplase in 90 days.

Objective To observe the changes in OLETF kideys at different stage and the beneficial influences by modulating serum lipids. Methods OLETF rats aged 8 wks were randomly divided into treated group and untreated group,and LETO rats served as normal control.Fenofibrate 20 mg/kg was given daily to the treated group.OGTT was performed at the age of 8,16 and 24 wks.Blood glucose,serum lipids and 24 h urine albumin excretion(UA) were investigated.The rats were killed at 16 and 24 wks of age,and the kidney sections were stained with PAS.Transforming growth factor-?_1(TGF?_1),vascular endothelial growth factor(VEGF) and fibronectin(FN) were investigated by immunohistochemistry assay.The electron microscope(EM) sections were made to measure GBM width and to observe the mesangial matrix.Results(1) Blood glucose had no significant difference between untreated and treated groups at 16 and 24 wks of age;(2) Fenofibrate decreased serum TG, increased HDL-C markedly but had no influence on LDL-C;(3) As aging,24hrs UA increased in untreated group,and reduced significantly in fenofibrate group at 24 wks of age;(4) TGF-?_1,VEGF and FN expressions were all higher in untreated group than in treated group at 24 wks of age.(5) EM revealed GBM obviously thickened and mesangial matrix widened in untreated group.Fenofibrate attenuated the kidney lesion greatly in EM picture.Conclusions (1) Dyslipidemia occurs prior to glucose metabolism abnormity in OLETF rats;(2) As aging,dyslipidemia progresses accompanying markedly the increased UA,enlarged glomeruli,thickened GBM and widened masangial matrix;(3) Modulating lipids early couldn′t improve glucose metabolism,but corrects dyslipidemia and reveals beneficial influence on kidneys;(4) The possible mechanism is that modulating lipids decreases TGF-?_1 and VEGF expressions.

SUMMARY Hyperparathyroidism is the clinical syndrome that results from elevated circulating parathyroid hormones,leading to multiple systems manifestations,and is divided into three kinds: primary, secondary and ternary.This patient’s main chief complaint was intermittent melena for 3 days,with the diagnosis of upper gastrointestinal hemorrhage according to endoscopy. Hypercalcemia, hypophosphatemia and high level of circulating parathyroid hormone and chronic renal failure were also found during hospitalization. Furthermore, MIBI showed a parathyroid adenoma located near the isthmus in the lower part of the left lobe. The patient had undergone nephrectomy because of kidney carcinoma 2 years ago. Primary hyperparathyroidism usually has the common gastrointestinal syndrome , but upper gastrointestinal hemorrhage reported as the chief complaint is rare and we had never seen similar reports before.

[Objective] To establish a method for rapid identification of Fructus Citri Sarcodactylis (FCS) from different production areas. [Methods] Fourier transform infrared (FTIR) spectroscopy was adopted to identify FCS. The height and position of the characteristic absorption peaks, and I value (a quantitative parameter of peak height ratio) were compared in FCS from different production areas. [Results] Each kind of FCS had their fixed range in peak height ratio I: 0.7-0.9 in FCS from Guangdong, 1.3-1.6 in FCS from Sichuan, 0.9-1.1 in FCS from Zhejiang, indicating that I value can be used to identify FCS from different areas . [Conclusion] For the identification of FCS from different production areas, FTIR spectroscopy is an effective method, in which there is no need for isolation, purification and chemical treatment.

Objective To investigate the relationship of serum levels of macrophage migration inhibitory factor (MIF), matrix metallo-proteinase-9 (MMP-9), hypersensitive C-reactive protein (hs-CRP) with the severity of acute cerebral infarction (ACI). Methods 101 pa-tients with ACI were envolved and divided into 3 groups according to the scores of National Institute of Health Stroke Scale (NIHSS):mild group (group A, n=38, NIHSS score<4), moderate group (group B, n=36, NIHSS score 4-15) and severe group (group C, n=27, NIHSS score>15). Meanwhile, 44 non-ACI inpatients with atherosclerosis were included as control group (group D). Their serum MIF and MMP-9 were detected with ELISA, and hs-CRP with immunoturbidimety. Results The levels of serum MIF, MMP-9 and hs-CRP ranged from more to less as groups C, B, A and D (P<0.05). There was positive correlation of MIF with MMP-9 (r=0.301, P<0.01) and hs-CRP (r=0.309, P<0.001). Conclusion Serum MIF, MMP-9 and hs-CRP levels increased with the severity in ACI patients, which may be prediction of athero-sclerotic plaque instability.

Pregnant women with subacute thyroiditis (SAT) are rare.One case was reported and the clinical features and management principles of SAT during pregnancy were reviewed.In pregnant women with SAT,the illness is usually not serious.If subclinical or clinical hypothyroidism develops,L-T4 must be given and thyroid function be monitored routinely,and the medication be adjusted carefully to ensure the maternal-fetal safety.

Objective To analyze the characteristics of PHPT patients of our hospital.Methods Retrospective analyze 82 PHPT patients who hospitalized in our hospital from 1974 to 2006,male 41,female 41,age 16～83 years,course 1 month～40 years.All of the final diagnosis was PHPT clinically,while 67 were confirmed by pathology.Results (1)The number of diagnosed PHPT patients was increasing year by year,the cases diagnosed in 2002—2006 were more than the sum of past years.(2)The first visit department was widespread for PHPT patients,up to 47.6% went to urology department firstly,while only 24% went to endocrinology department.(3)Clinical presentation:42.7% patients presented simple urinary system calculus,15.9% ostalgia with urinary system calculus,17.1% simple ostalgia,while 20.7% with pathologic fracture,and 7.3% chronic renal failure,3.6% peptic ulcer,2.4% chronic pancreatitis.69.5% occurred typical hypercalcinemia and hypophosphatemia,30.5% revealed hypophosphatemia chiefly.(4)The coincidence rate between the examinations preoperation and pathology:B type ultrasound 64.5%,CT scan 37.3%,99m Tc-MIBI scan 90%.(5)Pathology presentation:73% single adenoma,17.9% hyperplasia,2.9% adenoma with hyperplasia,1.5% carcinoma,other 4.5% only seen some parathyroid tissue.Conclusion PHPT patients have various clinical presentation,so there are generally missed diagnosis and misdiagnosis.we should investigate serum calcium,phosphate and PTH level to exclude PHPT.
