BACKGROUND: Vascular endothelial growth factor (VEGF) can accelerate neovascularization and, as a multifunctional cytokine, performs critical functions via its receptors in angiogenesis.OBJECTIVE: To investigate the expression of VEGF and its receptor FLT-1 and FLK-1 mRNA during the early stage of acute focal cerebral brain ischemia, and examine the relationship between the timing and location of their expressions.DESIGN: Randomized controlled study.SETTING: Department of Neurology of the First Hospital Affiliated to Jilin University and Teaching and Research Section of Pathology, Bethune Medical College of Jilin University.MATERIALS: This study was carried out between June 2001 and April 2002. Totally 130 adult SD rats were selected, with male and female in half, and randomly divided into normal control group (n=10), sham operation group (n=10), and cerebral ischemia group (n=110). The rats in cerebral ischemia group were further divided equally into 11 subgroups and examined at 0, 1, 2, 3, 6, 24, 48 hours and 1, 2, 3, 4 weeks after cerebral ischemia model establishment, respectively.METHODS: Permanent middle cerebral artery occlusion (MCAO) model was established in rats in cerebral ischemia group by ligation of the left common carotid artery, while the rats in the sham operation group received no artery ligation but with identical other treatments. The rats in the control group did not have any treatment. Reverse transcriptional (RT) PCR was used to detect the expression of VEGF and its receptor mRNA at different time points after ischemic model establishment, and neovascularization in the rats'brain was observed.MAIN OUTCOME MEASURES: ① Expression of VEGF and its receptor mRNA and ② neovascularization in the brain tissue at different time points of cerebral ischemia.RESULTS: Data of the 130 mice were statistically analyzed without losses.At 3, 6, 24, and 48 hours of ischemia, the number of cells positive for VEGF expression was 31.13±2.21, 43.11±2.43, 85.41±2.75 and 98.66±1.76 in each vision filed in the surrounding ischemic region, greater than the numbers in the central ischemic region at the corresponding time points (13.32±1.31, 19.40±3.22, 47.63±2.45, 57.32±3.35 in each vision field, respectively, P ＜ 0.05). VEGF mRNA expression gradually decreased since 48 hours after model establishment till recovering the control level by 2weeks. The expression of VEGF receptor FLT-1 mRNA, determined by the number of positive cells in each vision field at 3, 6, 24, and 48 hour after the ischemia in each vision field for FLK-1 mRNA at these time points in the peripheral ischemic regions, higher than those in the central ischemic regions (P ＜ 0.05), which recovered the control level 3 weeks after the ischemia (P ＜ 0.05). At 48 hours and 1 week after the ischemia, the number of microvessels in each vision field was 47.2±2.11 and 199.2±3.45 in the peripheral ischemic region, significantly higher than the number in the central ischemic region (29.4±2.37 and 76.6±4.62, P ＜ 0.05).CONCLUSION: VEGF and its receptors FLT-1 and FLK-1 mRNA are expressed in the neurons, glial cells and endothelial cells during the early stage of acute focal cerebral ischemia, and the expressions are significantly enhanced in response to ischemia, exhibiting temporal and spatial expression patterns.

Objective To investigate the relationship between apparent diffusion coefficient (ADC)value of rectal adenocarcinoma on DWI and its pathological grading.Methods The ADC values of 46 rectal adenocarcinomas were measured and compared with their histopathological grades.Results The 46 rectal adenocarcinomas included well differentiated adenocarcinomas in 14,moderate-ly differentiated ones in 20,and poorly differentiated ones in 12.The ADC values of well,moderately and poorly differentiated ade-nocarcinomas were (1.125±0.103)×10 -3 mm2/s,(1.030±0.098)×10 -3 mm2/s and (0.922±0.091)×10 -3 mm2/s,respective-ly,exhibiting a statistical difference (χ2 =1 7.35 1,P =0.000).Mann-Whitney U test showed that difference in ADC value between different histopathological grades was statistically significant.Conclusion ADC value of rectal adenocarcinoma can be used as a bio-marker for cell grading to guide treatment decision and prognosis assessment.

ObjectiveTo examine biochemical characteristics of the frontal lobe and hippocampus in unaffected parentsof schizophreniaprohandsusingprotonmagneticresonancespectroscopy(1H-MRS).Method 19 unaffected fathers of schizophrenia probands with matched 19 male healthy control subjects and 24 unaffected mothers of schizophrenia probands with matched 24 female healthy control subjects were included in the study.1 H-MRS was performed in two sides of the hippocampus and frontal lobes regions.The ratios of N-Acetylaspartate ( NAA ),choline (Cho) to creatine (Cr) were measured.One-sample T test and paired-samples t test were used for statistic process.ResultsUnaffected mothers of schizophrenia probands had a higher Cho/Cr ratio ( left ( 1.10 ± 0.13,right ( 1.08 ± 0.12 ) ) in the frontal white matter compared with matched female health control subjects(left( 1.03 ± 0.10),right( 1.02 ± 0.09 )).The NAA/Cr ratio was significantly reduced in the left frontal white matter of female health control subjects compared to right( 1.64 ± 0.12 vs 1.74 ± 0.13 ),but this difference was not observed in unaffected mothers of schizophrenia probands.There were no significant differences in metabolites for frontal lobe and hippocampus regions between unaffected fathers of schizophrenia probands and male healthy control subjects groups( all P＞0.05 ).ConclusionThe results implicate that the metabolic abnormalities and disappeared asymmetry of NAA/Cr might exist in the frontal white matter among unaffected mothers of schizophrenia probands.

ObjectiveTo identify the metabolic alterations on prefrontal lobes and hippocampus in male patients with the first-episode mania using proton magnetic resonance spectroscopy(H-MRS).Method 18 male patients with the first-episode mania and 27 healthy subjects matched for age,gender,and years of education were included in the study.1 H-MRS was performed in two sides of the hippocampus and frontal lobes regions.The ratios of N-acetylaspartate (NAA),choline (Cho) to creatine (Cr) were measured.One-sample t test and paired-samples t test were used for statistic process.ResultsMale patients with the first-episode mania presented decreased NAA/Cr in left frontal lobe and hippocampus regions when compared to normal controls( left frontal lobe (1.68 ±0.19 vs 1.86 ± 0.19),hippocampus ( 1.32 ± 0.10 vs 1.43 ± 0.16 ),P ＜ 0.01 ),but there were no significant difference in NAA/Cr for right frontal lobe and hippocampus regions between groups ( all P ＞ 0.05 ).Two groups also showcd no significant difference for Cho/Cr in bilateral frontal lobe and hippocampus (P ＞ 0.05 ).Conclusion There is significant difference of manifestation of 1H-MRS between male patients with mania and normal controls,which reflects neuronal dysfunction in the prefrontal lobes and hippocampus.

Objective:To explore the therapeutic characteristics of population with gout achieving treat-to-target (T2T) indicators through real-world research and evaluate their safety.Methods:A total of 3 287 patients diagnosed with gout by rheumatologists in 21 first-class tertiary hospitals in 10 provinces, municipalities, and autonomous regions in China from January 2015 to December 2021 were included in this polycentric cross-sectional study. The database included patients′ general information, disease characteristics, and clinical application of traditional Chinese and Western medicine treatment measures. SPSS and Excel software were used for data analysis. Frequency analysis, cluster analysis, and factor analysis were used to summarize the characteristics and rules of treatment measures for patients with gout who achieved the target after treatment. The occurrence of adverse events (AE) was recorded during treatment.Results:After treatment, 691 visits (7%) achieved the serum urate (SUA) target, and the most frequent use of urate-lowering therapy (ULT) was febuxostat, followed by benzbromarone. The most common treatment options were following: GroupⅠ: traditional Chinese medicine (TCM) decoction-TCM external treatment-physical exercise-proprietary Chinese medicine; GroupⅡ: ferulic acid-nonsteroidal anti-inflammatory drugs (NSAIDs); Group Ⅲ: allopurinol-sodium bicarbonate-benzbromarone; Group Ⅳ: glucocorticoid-colchicine; Group Ⅴ: febuxostat. A total of 5 898 visits (60%) chieved manifestations of joint pain VAS scores target, and the most frequently used drug to control joint symptoms was NSAIDs. The frequency of use of drugs to control joint symptoms were 2 118 times (usage rate reached 35.9%), while the frequency of ULT were 2 504 times (usage rate reached 42.5%), which was higher than the joint symptom control drug. The most common treatment options were following: Group Ⅰ: proprietary Chinese medicine-TCM decoction-TCM external treatment-physical exercise; Group Ⅱ: NSAIDs-colchicine hormones; Group Ⅲ: allopurinol, Group Ⅳ: benzbromarone; Group Ⅴ: febuxostat. A total of 59 adverse events occurred during treatment.Conclusion:The proportions of gout patients who reach target serum urate level & good control of joint symptoms are both very low, and ULT and anti-inflammatory prescription patterns are very different from international guidelines, so it is necessary to strengthen the standardized management of gout patients. At the same time, life intervention measures account for a certain proportion of the treatment plans for the T2T population, and further exploration is needed.
