Objective To investigate the changes of learning and memory function ,vascular endothelial growth factor (VEGF) and heme oxygenase‐1(HO‐1) expression in cerebral cortex and hippocampus of chronic ischemic vascular dementia rats . Methods Thirty‐six healthy SD rats were divided into the control group ,sham operation group and model group ,12 cases in each group .The chronic ischemic vascular dementia rat model was established by the permanent bilateral carotid artery occlusion The sham operation group received the same treatment to the model group except without bilateral carotid artery occlusion .The learning and memory abilities were tested by the Morris water maze experiment and climbing rope strength experiment at 1 ,4 ,8 ,12 weeks respectively .The expressions of VEGF and HO‐1 in rat cerebral cortex and hippocampus was determined by immunohistochemical SP technique .Results The escape latency time at 8 ,12 weeks in the model group was longer than that in the sham operation group and control group ,and the number of crossing the platform was less than that in the sham operation group and control group ,the differences were statistically significant (P<0 .05);the time of climbing at 1 -12 weeks had no statistical difference between the model group and the sham operation group and between the model group and the control group (P>0 .05) .The positive expression of HO‐1 and VEGF protein contents in the control group and sham operation group was less than that in the model group with sta‐tistical difference(P<0 .05) .Conclusion Chronic cerebral hypoperfusion has a permanent damage to the learning and memory abil‐ities in rats ,while has no influence on the motor function .VEGF and HO‐1 may play a protective role in chronic cerebral ischemia .

There are 63 species Melastomataceae plants in 17 genus, which widely distribute along Yangtze River and the south of China ranging from Tibet autonomous region to Taiwan province. They used as herb medicine in China. A large part of the Melastomataceae plants have bitter, pungent and sweet taste. The meridian distribution of them is liver, spleen and stomach, they have many functions such as "cure rheumatism", "clear heat" and "detoxication", "regulate the flow of qi and alleviate pain", "diuresis and detumescence", "activate the blood and eliminate stasis". Melastomataceae plants not only have exact medical value, but also have abundant resource. So it has very bright perspective of exploitation and utilization.

Children, especially those younger than 5 years of age and those with chronic medical conditions, such as respiratory diseases, neurological diseases, immunosuppression, receiving longterm aspirin therapy, obesity or co-infection with bacteria, are at an increased risk of pandemic H1N1 infection-related complications. This paper reviews the underlying medical conditions associated with death or complications of pandemic H1N1 infection in children.

OBJECTIVETo compare the safety and efficacy of myocardial contrast enhancement (MCE)-guided and angio-pressure (AP)-guided transcoronary ablation of septal hypertrophy (TASH) for patients with hypertrophic obstructive cardiomyopathy (HOCM).

METHODSTASH was performed under MCE-guide (n = 47, group I) or AP-guide (n = 25, group II) for drug-refractory patients with HOCM. Myocardial perfusion imaging (MPI) data as well as other clinical data were compared.

RESULTSTASH both under MCE-guide or AP-guide resulted in similar and significant reduction of left ventricular outflow tract gradient (PG) and associated with significant symptom improvement (all P < 0.001). Dosage of ethanol use, peak-level of CK-MB and ablated myocardial area and incidence of arrhythmia were also similar between the two groups.Similar left ventricular/atrial dimension changes post TASH were observed in the 2 groups during follow-up. However, the first selected septal vessels were changed under MCE in 6 patients.

CONCLUSIONSOur data demonstrated that the MCE-guided TASH was not superior to AP-guided TASH in safety and efficacy. However, MCE-guided TASH can avoid the misplace of ethanol to avoid innocent myocardial ablation.

Objective:To investigate the risk factors of acute symptomatic seizures (ASS) and epilepsy in children with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD).Methods:A ambispective cohort study was used including 74 children with MOGAD who were admitted to the Department of Pediatrics of Peking University First Hospital from January 2013 to June 2023 and were followed up. Demographic information, clinical information, treatment status, ASS and epilepsy status were collected. The clinical phenotypes were classified. According to the presence or absence of ASS in the course of disease, the children and the course of disease were divided into groups with and without ASS. Chi-square test, Fisher exact test and Mann Whitney U test were used to analyze the correlation between symptoms and auxiliary examination characteristics and the occurrence of ASS in the two groups of children. Multivariate Logistic regression analysis was used for multivariate analysis. Results:The onset age of the 74 children with MOGAD was 6.58 (3.80, 9.67) years, including 38 females (51.4%) and 36 males (48.6%). The duration of the final follow-up was 2.67 (1.10, 4.12) years, with a total of 239 times acute clinical episodes. ASS occurred in 39.2% (29/74) children during the course of disease and in 29.3% (70/239) of attacks. The common phenotypes were ADEM (67 times (28.0%)), optic neuritis (37 times (15.4%)) and cerebral cortical encephalitis (31 times (13.0%)) in 239 times acute clinical episodes. The incidence of ASS in ADEM and cerebral cortical encephalitis phenotype was 28.4%(19/67) and 100.0% (31/31), respectively. Multivariate analysis showed that cortical involvement on magnetic resonance imaging during clinical attacks was an independent risk factor for ASS ( β=-1.49, OR=0.23) after excluding attacks involving only optic nerve or spinal cord (49 episodes). During the follow-up, 5 children (6.8%) had epilepsy, and all children with epilepsy had multiple clinical attacks of MOGAD and previous ASS. Conclusions:Cortical involvement on magnetic resonance imaging during clinical episodes is an independent risk factor for ASS in children with MOGAD. All MOGAD children with epilepsy had ASS and multiple MOGAD clinical episodes in the past.

BACKGROUND/AIMS: The aim of this study was to investigate the associations between obesity and erosive esophagitis (EE) or Barrett's esophagus (BE) in a Chinese population. METHODS: Data from subjects were retrospectively collected from 2006 to 2009. Individuals with BE were identified and age- and sex-matched at a 1:2 ratio with normal esophagocardial junction and EE patients. The subjects were stratified into two groups: the normal weight group and overweight/obesity group (body mass index ≥25 mg/m²) or the normal waist group and abdominal obesity group (waist circumference ≥90 cm for men and ≥80 cm for women). RESULTS: Overall, 45%, 72%, and 52% were overweight/obese and 23%, 65%, and 18% had abdominal obesity in the normal, EE, and BE groups, respectively. Positive associations were identified between EE and overweight/obesity (odds ratio [OR], 3.14; 95% confidence interval [CI], 1.75 to 5.66) and abdominal obesity (OR, 6.22; 95% CI, 3.34 to 11.57); however, the associations were nonsignificant between BE and overweight/obesity (OR, 1.32; 95% CI, 0.67 to 2.61) or abdominal obesity (OR, 0.73; 95% CI, 0.31 to 1.73). Female BE patients had a significantly increased rate of being overweight/obese. CONCLUSIONS: Obesity is a contributing factor in EE. The association of BE and obesity was not significant, with the exception of female BE cases.

BACKGROUND/AIMS: Gastroesophageal reflux disease (GERD), functional dyspepsia (FD), and peptic ulcer disease (PUD) impact the daily lives of affected individuals. The aim of this study was to compare the risk factors and impacts on life quality of overlapping FD or PUD in patients with GERD. METHODS: Data from patients diagnosed with GERD were collected between January and November 2009. FD was defined using the Rome III diagnostic criteria. The overlapping GERD-FD or GERD-PUD groups were classified as concomitant GERD and FD or peptic ulcers. The characteristics of these individuals were analyzed. RESULTS: There were 63, 48, and 60 patients in the GERD only, overlapping GERD-FD, and overlapping GERD-PUD groups, respectively. Significantly younger age, female gender, lower body weight and body mass index, and higher rates of tea consumption were noted in the GERD-FD group. Patients in the GERD-FD group exhibited the lowest quality of life scores, both with respect to physical and mental health, on the Short Form 36 domains. CONCLUSIONS: Patients with concomitant GERD and FD were more likely to be younger and female. Overlapping GERD and FD had the worst impact on the quality of life of the affected individuals.
