BACKGROUND: It has been proved that interleukin-18 (IL-18) involves in the development of acute cerebral infarction (ACI) and is positively correlated with the time of brain stroke onset, erythrocyte sedimentation rate (ESR), as well as neurological deficit and low-density value of brain CT.OBJECTIVE: To investigate the dynamic changes of serum IL-18 in the course of ACI.DESIGN: Verification analysis with patients as subjects and healthy volunteers as controls.SETTING: Department of neurology of a municipal hospital.PARTICIPANTS: Totally 46 inpatients (29 males and 17 females) with ACI were randomly selected from the Department of Neurology of People's Hospital, Maoming City, between December 2002 and January 2004.Meanwhile, 40 healthy controls (27 males and 13 females) were recruited from those who came to the hospital for routine physical examination. All the participants signed informed consent.METHODS: Fasting peripheral vein blood of 2 mL was collected from the patients on the 1st, 7rh, 14th and 21st days of ACI onset, and from healthy controls on the day of routine examination. The blood samples were centrifuged at 3 000 r/minute for 15 minutes at 4 ℃, and then the supernatant was collected for detecting IL-18 level by ELISA.MAIN OUTCOME MEASURES: The serum IL-18 level of patients on the 1st, 7th 14th and 21st days of ACI onset and that of healthy controls on the day of routine examination.RFSULTS: Totally 46 patients and 40 healthy controls were enrolled in this study and all data were statistically analyzed. The level of serum IL-18 was significantly higher in the patients with ACI than in normal controls on the 1st and 7th days of onset [(178±41) ng/L, (104±34) ng/L, (65±14) ng/L, P ＜ 0.01],but was similar on the 14th and 21st days [(88±36) ng/L, (72±33) ng/L,(65±14) ng/L, P＞ 0.05]. The level of serum IL-18 in ACI patients was significantly higher on the 1st day than on the 7th, 14th and 21 st days of the onset (P ＜ 0.05-0.01); moreover, it was also significantly higher on the 7th day than on the 21st day of the onset (P ＜ 0.05).CONCLUSION: The level of IL-18 increases obviously on the 1st day of ACI onset, and gradually decreases with the extended course of disease and time of treatment.

Objective To synthesize 4 kinds of 111 In?TPP cations and evaluate their properties as tumor cationic radiotracers in vivo and in vitro. Methods DO3A?xy?TPP, DO3A?xy?mTPP, DO3A?xy?dmTPP and DO3A?xy?tmTPP were radiolabeled with 111 In;their lipid?water partition coefficients and in vivo and in vitro stability were evaluated. The binding affinities of 4 kinds of 111 In?radiotracers were determined in cell uptake and cell efflux assay using U87MG tumor cells. Biodistribution studies and γ imaging studies were performed using the athymic nude mice bearing U87MG human glioma xenografts to explore the biologi?cal properties of 4 kinds of 111 In?radiotracers. One?way analysis of variance was used. Results The labeling yields of 4 kinds of 111 In?radiotracers were all above 85%, and the radiochemical purity were all greater than 99% after purification. Binding assay in U87MG cells showed that 4 kinds of radiotracers had great binding affinity and cell retention ability, and 111In?DO3A?xy?mTPP had the best binding ratio (1?49%;F=177.8, P<0.05) . Gamma imaging and biodistribution results showed that the U87MG tumors could be clearly visualized by 111In?DO3A?xy?mTPP, 111In?DO3A?xy?dmTPP and 111In?DO3A?xy?tmTPP, and the liver uptake of the 3 tracers was lower than that of 111In?DO3A?xy?TPP. In particular, 111In?DO3A?xy?mTPP had the best tumor/liver ratio (0.13±0.05, 2 h postinjection;F=9.4, P<0?05). Conclusions The tumor?targeted ability of 111In?DO3A?xy?mTPP is better than those of 111In?DO3A?xy?dmTPP, 111In?DO3A?xy?tmTPP and 111In?DO3A?xy?TPP, suggesting that it has the potential to be a promising tumor cationic radiotracer.

Racemic (±)-F18 (10-chloromethyl-11-demethyl-12-oxo-calanolide A), an analog of nature product (+)-calanolide A, is a new anti-HIV-1 nonnucleoside reverse transcript inhibitor (NNRTI). A successful enantioseparation of (±)-F18 offering (R)-F18 and (S)-F18 was achieved by a chiral stationary phase prepared HPLC. Their absolute configurations were determined by measurement of their electronic circular dichroisms combined with modem quantum-chemical calculations. Further investigation revealed that (R)-F18 and (S)-F18 shared a similar anti-HIV activities, however, (R)-F18 was more potent than (S)-F18 against wild-type virus, K101E mutation and P225H mutation pseudoviruses.

Objective To observe the sub-chronic effects of low doses of arsenic poisoning in rabbits exposed to different periods on some of the serum enzymes and biochemical indicators, and to provide the basis for screening of meaningful hematologic indicators for early diagnosis of arsenic poisoning. Methods Twelve adult rabbits,weighing 2.0 - 3.5 kg, were randomly divided into four groups, 3 in each group, and they were fed with drinking water containing sodium arsenite 0(control),0.01,0.05,0.25 mg/L, respectively. Serum alanine aminotransferase (ALT), aspartate amino transferase (AST), alkaline phosphatase (ALP), γ-glutamyl transacylase (y-GT), total protein(TP), albumin(ALB), globulin(GLP), and ALB/GLP of rabbit were measured by SYSMEX-180 automated biochemistry analyzer after 8 weeks and 12 weeks exposure. Results The results showed that ALT in 0.05 mg/Lgroup of 12 week[(60.00 ± 4.14)U/L]increased significantly compared with the control[(41.50 ± 2.12)U/L, P ＜0.05];AST in 0.25 mg/L group of 8 week and 12 week[(46.50 ± 3.21 ), (52.33 ± 3.81 )U/L]increased significantly compared with the control[(21.33 ± 3.53), (29.50 ± 3.23 )U/L, all P ＜ 0.05];ALP in 0.05 mg/L and 0.25 mg/L group of 12 week [(78.68 ± 4.85 ), ( 103.00 ± 7.83 ) U / L]increased significantly compared with the control [(45.50 ± 5.50)U/L, all P ＜ 0.05];γ-GT in 0.05 mg/L group of 12 week[(19.33 ± 7.50)U/L]increased significantly compared with the contro1[(8.50 ± 3.53)U/L, P＜ 0.05]. TP, ALB, GLP, ALB/GLP of different groups of 8 week and 12 week were not significantly different statistically(F= 0.77,0.02,0.16,3.14 and 0.51,0.29,0.41,0.52, all P ＞ 0.05). Conclusions Zero point zero five mg/L and higher doses of sub-chronic arsenic exposure has some major damage to the liver. Compared with other serum enzymes and the biochemical indexes, serum AST is a early sensitive indicator of liver injury of the arsenic poisoning.

Objective To analyze lesion patterns of lacunae-sized infarctions in the perforating arterial territory in terms of shape and determine whether the lesion patterns associate with their prognosis. Methods We consecutively included patients with confirmed lacunae-sized acute ischemic infarcts in the penetrating arterial territories on diffu?sion-weighted imaging(DWI)from Guangxi stroke center between June 2012 to September 2013. Based on diffu?sion-weighted MRI, the shape of ischemic infarcts were divided into oval or conglomerated beads shape. Demographics, risk factors and NIH Stroke Scale (NIHSS) score at admission and discharge, Ranking score after three months and stroke mechanisms were analyzed. Results Among 189 patients, the conglomerated beads shape and oval shape of infarcts were detected in 69(36.5%)and 120(63.5%)patients, respectively. There were not difference between these two groups in de?mographics, risk factors and NIH Stroke Scale (NIHSS) score at admission. However, the maximal diameter of the lesion was significantly larger in the conglomerated beads shape group than in the oval shape (13.8±2.3 mm vs. 10.6±3.2 mm, P=0.006). Early neurologic deterioration was also more commonly detected in the conglomerated beads shape group than in the oval shape group (24.6% vs. 5.0%,P=0.009). Early neurologic rehabilitation was slower in the conglomerated beads shape group than in the oval shape group(30.5% vs. 10.8%,P=0.018). Multiple logistic regression analysis showed that the conglomerated beads shape was significantly associated with early neurologic deterioration (OR=7.55, 95%CI:1.73~33.25,P=0.010) and was negatively related to early neurologic rehabilitation(OR=5.75, 95%CI:1.53~28.70,P=0.030). Conclusions The conglomerated beads shape of lacunae infarction is significantly associated with ear?ly neurologic deterioration and is negatively related to early neurologic rehabilitation.
