Objective To assess the safety among acute ischemic stroke patients with asymptomatic intracranial aneurysm after the administration of intravenous thrombolysis.Methods We searched database including Wanfang,CNKI,VIP,Pubmed,EMBASE,EBSCO HOST and Metstr data for all the cohort studies on the use of thrombolysis for acute ischemic patients with asymptomatic intracranial aneurysm,and ascended the correlated references listed on the articles.Meta-analysis was conducted based on the methods recommended by the Cochrane collaboration.The outcomes of the meta-analysis were intracerebral hemorrhage (ICH),symptomatic intracerebral hemorrhage (sICH),subarachnoid hemorrhage (SAH).Results Four cohort studies included 707 patients,of whom 48 patients had asymptomatic cerebral aneurysms.The risk ratio prevalence of ICH among those patients did not differ statistically with those without aneurysms (RR =1.17,95％ CI 0.69-1.99,P =0.56).No statistical differences were found in both odds ratio prevalence of sICH (OR =1.70,95％ CI 0.44-6.59,P =0.45) and SAH (OR =1.13,95％ CI 0.20-6.27,P =0.89) between the patients with asymptomatic cerebral aneurysms and those without.Conclusion Current evidence did not indicate that the risk of hemorrhage increased in acute ischemic stroke patients with asymptomatic intracranial aneurysm after the administration of intravenous thrombolysis.

The change of PNA receptors on the surface of thymocytes in protein deficient mice was investigated. After the mice were fed with protein deficient diet, the body weight continuously declined and the thymus gradually a-trophied. Qualitative test of FITC-PNA indicated the number of PNA positive cells was reduced and the fluorescent antibody reaction on the surface of PNA positive cells weakened. Quantitative test of FITC-PNA showed the amount of FITC-PNA coupled on the surface of PNA positive cells was mark- edly decreased as compared with the cotrol (P

A 53-year-old woman presented with arthralgia and dyspepsia on exertion.Symmetrical joint swelling and pain of bilateral hands with pigmentation sedimentation in the articular surfaces,dry cough and short of breath were the main clinical manifestations.Elevated levels of erythrocyte sedimentation rate (89 mm/1 h),C-reactive protein (64.45 mg/L),IgG (31.22 g/L) and IgA (5.44 g/L).Rheumatoid factor was positive and anti-cyclic citrullinated peptide antibody was negative.Chest high-resolution computed tomography scan found that diffusely distributed lung nodules,round cysts with varying sizes and patchy ground glass opacities.A significant plasma cell infiltration and amyloid deposition were seen in lung tissue.The patient was finally diagnosed as rheumatoid arthritis,interstitial lung disease and pulmonary nodules.Combination therapy of prednisone 7.5 mg qodpo,thalidomide 50 mg qdpo,tocilizumab 560 mg iv once per month for 1 month.Chest computed tomography showed stable lung nodules,however,pulmonary interstitial lesions gradually aggravated.

Objective:To study the effects of pioglitazone on atherosclerosis on ApoE-/-mice,and to investigate the roles of adiponectin and its receptors.Methods:ApoE-/-mice were fed with high-fat chow for the induction of atherosclerosis and were divided into three subgroups:placebo(n=10),low-dose[10 mg/(kg?d),n=10] pioglitazone therapy,and high-dose[20 mg/(kg?d),n=10] pioglitazone therapy.C57BL/6J wild type mice(n=9) were used as control.Aortic atherosclerosis and intima-media thickness(intima-media thickness,IMT) of abdominal aorta were monitored,and plasma adiponectin was also measured.Expression levels of the adiponectin receptor 1(AdipoR1)and adiponectin receptor 2(AdipoR2) in vessels were analyzed(RT-PCR).Results:(1) Aortic atherosclerotic lesions were observed in ApoE-/-mice but not in wild type mice.Interestingly,these lesions were significantly prevented by high-dose pioglitazone therapy.Compared with wild type mice,ApoE-/-mice had increased IMT of abdominal aorta [(0.290?0.063 vs 0.178?0.012) cm,P

Objective To determine the activities of 131I for treating differentiated thyroid carcinoma with diffuse pulmonary metastases ( DTC-DPM ) from the perspective of internal radiation dosimetry.Methods According to Medical Internal Radiation Dosimetry (MIRD) schema, the activity constraint,from which the whole bdy retention at 48 h should not exceed 2.96 GBq (2.96 GBq rule), was converted to dose-rate constraint(DRC) to lungs at 48 h ( DRCLU ·48 h ) in 131I therapy for DTC-DPM. Based on the assumption of DRCLU·48 h at 48 h in lung, the fractions of whole body activities ( F48 ), the effective half times of 131I in lungs ( TLL ) and the remainder of body ( TRB ) were 0.6-0.9, 20- 120 h, and 10- 20 h, respectively. The maximum safe activities of 131I for different human phantoms from the Organ Level Internal Dose Assessment (OLINDA) software were calculated. Results According to MIRD schema and 2.96 GBq rule, DRCLU ·48 h should not exceed 46.4 mGy/h in 131I therapy for DTC-DPM. Depending on varying F48 h,TLL and TRB, the maximum safe activities of 131I were 6.77-81.36, 5.29-56.20, 5.08-55.19 and 3.87-40. 52 GBq for the male adult, female adult, 15-year-old, and 10-year-old patients with DTC-DPM, respec tively. Conclusion Dosimetry-guided 131I therapy for DTC-DPM considers adequately the differences of 131I kinetics in individual patients and can adjust administered activities of 131I on the precondition of avoiding radiological pneumonitis and pulmonary fibrosis.

OBJECTIVETo investigate the effects of glutamine-enriched enteral nutrition on the nutritional status and prognosis of patients with severe head injury.

METHODSThirty-three patients with severe head injury were randomly divided into control group (C, 15 cases) and glutamine-enriched group (Gln, 18 cases). Patients in both groups were given routine treatment and enteral nutrition with the same amount of nitrogen and calorie. Patients in Gln group were given glutamine 0.5 g x kg(-1) x d(-1) additionally added into the nutrient fluid. Vital signs and the occurrence of side effects of all patients were observed before and after nutrition support. Venous blood and urine sample of all patients were collected before and 7, 14 days after treatment to determine the parameters of blood, urine routine and hepatorenal function. At the same time points, body mass, skin fold thickness at the region of triceps brachii (TSF), upper arm circumference (AC), upper arm muscle circumference (AMC) and fasting blood glucose of all patients were detected and determined, Glasgow coma scale (GCS) scoring was performed. The length of hospital stay of all patients was recorded.

RESULTSVital signs and parameters of blood, urine routine and hepatorenal function of patients in 2 groups after nutrition treatment were close to those before treatment. Side effects, such as nausea and diarrhea occurred with spontaneous remission in a few patients. There was no statistical significant difference between 2 groups, and within each group before and after treatment, in respect of body mass and TSF (P > 0.05). Values of AC and AMC of patients in Gln group were obviously higher than those of C group (P < 0.01) on post-treatment day 14. Fasting blood glucose and GCS score of all patients before treatment were close to those on post-treatment day 14 (P > 0.05). Fasting blood glucose and GCS score of patients was respectively lower and higher in Gln group than that in C group on post-treatment day 7 (P < 0.05). Length of hospital stay of patients in Gln group (25 +/- 9) d was obviously shorter than that of C group (33 +/- 12) d (P < 0.05).

CONCLUSIONSGlutamine-enriched enteral nutrition can control the blood glucose level, prevent the loss of lean tissue, improve nutrition status of patients,shorten hospital stay, and accelerate the recovery of patients to some extent.

Objective To evaluate the difference of Doumas′method and 15 commercial serum total protein ( TP ) methods based on EP9-A3.Methods Serum panels were quantified for TP with Doumas′method and measured in parallel with 15 commercial methods.The linear regression analyses were performed, followed by calculating relative deviation and 95%CI between commercial method and Doumas′method at three different medical decision levels (45 g/L, 60 g/L, 80 g/L).We also calculated relative deviation, 95% limit of agreement ( LoA ) and 95% CI based on classical and improved Bland-Altman method at three different medical decision levels.If both the relative deviation and 95%CI were within 5%, we conside red the commercial serum total protein method was comparable to Doumas′method.Results (1) All assays presented high correlation ( r>0.975, P<0.001) with the Doumas′method.All assays showed that the relative deviations and 95%CIs were within the biological total error goal (5%) at medical decision levels based on regression analysis.(2) Based on classical and improved Bland-Altman method, fourteen of 15 commercial methods showed that the relative deviations and 95%CIs were within +/-5%. Conclusions All commercial assays are comparable to Doumas′method at medical deviation levels.There is no difference between regression analysis and Bland-Altman method for comparison study.

Objective To summarize the clinical experience of standard piggyback liver transplantation(SPBLT) and modified piggy-back liver transplantation(MPBLT) in the treatment of Wilson′s disease(WD).Methods The clinical records of 29 cases of WD who underwent piggyback liver transplantation over the recent 12 years were analyzed retrospestively.Among them,there were 22 male and 7 female patients,with 6cases aged 8-14y and 23 cases aged 24-37y,who underwent liver transplantation because of chronic advanced liver disease(18cases),fulminant hepatic failure(2 cases),or with normal liver function(9 case),and among them,24 cases showed neurological dysfunction.The modes of operation included SPBLT(13 cases) and MPBLT(16 cases).Results The patients were followed up for 1 month-12 years with the median follow-up time of 47 months.Four patients died in the perioperative period,of which 2 died of hepatic failure due to obstruction of hepatic venous return after SPBLT,and 2 died of hepatic artery thrombosis and bile leakage combined with severe infection.The recipient survival rate at 1 year and 3 years was 86% and 79% respectively.One patient has survived for 12 years.All the levels of serum copper and copper-protein recovered to normal in four weeks post-operatively.Neurological symptoms improved in varying degrees after operation.Conclusions WD patients who undergo PBLT can expect a satisfactory clinical outcome and a good quality of life,and MPBLT can effectively reduce the complications of operation and improve the operation survival rate.
