Objective To explore the repetitive expressions of autophagy marker protein-rnicrotubule-associ-ated protein 1 light chain 3 (LC3) in hippocampus in newborn rats with recurrent seizure and the influence of 3-methyladeine (3-MA) on LC2 expressions. Method Seventy-two 6-day-old SD rats were randomly (random nam-ber) divided into the recurrent neonatal seizure group (RS group, n = 24), the 3-MA-treated seizure group (3-MA group, n = 24) and control group (n = 24). Rats in RS group were subjected to 55 attacks of seizure induced by flurothyl in 9 successive days from the 6th postnatal day (P6). In 3-MA group, 2 μL of 3-MA was injected every day till seizure induced. Western blot analysis was used to determine LC3 protein level in hippocampus at different intervals of 1.5 h,3 h,6 h and 24 h after the last convulsion. The LC3 protein level was analyzed with Dunnett test after ANOVA. Results LC3 protein levels in RS group at the different intervals were significantly higher than those in the control group and in 3-MA group (F =4.70,5.28,8.51 and 5.89, respectively, P <0.05), and there were no significant differences in LC3 protein level between 3-MA group and control group at those intervals (P > 0.05). Conclusions The autophagy/lysosomal pathway is immediately activated after recurrent seizure evidenced by the elevated expressions of LC3 in hippocampus. The 3-MA is involved in the regulation of autophagy/ lysosomal pathway by down-regulating the expressions of LC3.

0.05).However,body mass index and hemoglobin level were significantly higher in the slow coronary flow group compared with the control group(26.9?3.2 kg/m2 vs.24.9?2.9 kg/m2,P

0.05). Conclusions Autop-hagy/lysosomal pathway was activated immediately after recurrent seizures as indicated by the elevated expression of Beclin1 in cerebral cortex. 3-MA was involved in the regulation of autophagy/lysosomal pathway by down-regulating the expression of Beclin1.

A cross sectional study of 769 patients was performed to evaluate the association of blood uric acid with coronary heart disease (CHD) in different metabolic disorders. It showed that uric acid was not independently associated with CHD. However, when the other abnormal metabolic factors were absent, uric acid might be related to CHD.

Objective To investigate the abnormal situation and the characteristics of body mass index(BMI),blood pressure (BP),blood lipid(BL),and fasting plasma glucose(FPG) in residents of Chongqing.Methods Data of BMI,BP,BL and FPG were obtained from 16 367 residents receiving regular health examination in our Hospital in 2006.Results These metabolic indicators of this group were abnormal:The detection rate was 33.2%(42.5% in male and 17.6% in female)for overweight;7.4%(9.7% in male and 3.5% in female) for obesity;25.4%(30.0% in male and 17.6% in female) for hypertension;,38.9%(41% in male and 35.5% in female) for total cholesterol;26.1%( 34% in male and 12.8% in female) for triglyceride;23.7%(26.8% in male and 18.6% in female) for low-density lipoprotein;8.2%(11.8% in male and 2.2% in female) for high-density lipoprotein;3.2%(3.8% in male and 2.2% in female) for impaired fasting glucose;and 3.2%(3.9% in male and 2.0% in female) for diabetes meUitus.The detection rate of these metabolic disorders was significantly higher in men than those in women,and increased with age,which was significantly higher in people aged 30-40 years than in people aged less than 30 years.Conclusion The levels of BMI,BP,BL and FPG of health examination residents in Chongqing had its unique characteristics,and were abnormal significantly,it was very important to take regularly health examination after 30 yrs old.

ObjectiveTo prospectively compare the effects of Prestige LP cervical disc replacement with those of anterior cervical discectomy and fusion (ACDF) in treatment of cervical disc herniation.MethodsFrom January 2008 to March 2010,a total of 87 patients were enrolled at our site as study investigating ACDF versus Prestige LP cervical disc prosthesis.Forty-four patients received the investigational device (arthroplasty group) and 43 underwent a single-level ACDF (fusion group).Visual analogue scale(VAS) neck/arm pain,Japanese Orthopedics Association (JOA) score,Short Form-36 (SF-36) both physical and mental,flexion-extension range of motion of operative and adjacent segments were evaluated preoperatively and 1 week and 3,6,12,24 months postoperatively.ResultsA total of 78 patients (89.7％) were followed up for an average 12.4 months(range,6-24).Both groups have favorably demonstrated improved functional outcomes for JOA,VAS scores and SF-36.The improvement in the VAS and JOA scores were equivalent at each follow-up point between the two groups(P＞0.05).However,arthroplasty group had statistically significant improvement as assessed by the SF-36 scores compared with the fusion group at some follow-up points (P＜0.05).In arthroplasty group,the postoperative range of motion of operative and adjacent segments showed no statistical difference with the preoperative counterpart(P＞0.05),and fusion was successful in 92.1％ of control patients.ConclusionPrestige LP cervical disc replacement is a feasible alternative to ACDF for patients with persistently symptomatic cervical disc disease and matching the inclusion criteria.

To investigate the clinical features and principles of diagnosis and treatment of early postoperative inflammatory ileus (EPII). The clinical data of 69 patients with EPII treated in this hospital were retrospectively reviewed. EPII mostly occurred in 3-11d after abdominal surgery, and the average time was 5d. Sixty two cases were cured in a mean period of (22±13)d through combination therapy including gastroenteral decompression, somatostatin, dexamethasone and total parenteral nutrition (TPN). Seven cases were cured by operation. EPII is a special type of early intestinal obstruction which often occurs in two weeks after abdominal operation. Its typical symptoms are abdominal distension; conservative therapy is effective for most cases and reoperation is usually contradicted.

Objective To evaluate the effects of mild hypothermia therapy on cerebral function and edema as assessed by magnetic resonance imaging (MRI ) during the first 72 hours after restoration of spontaneous circulation (ROSC)in a porcine model.Methods Ventricular fibrillation was induced in 33 Inbred Wuzhishan miniature swine.After ventricular fibrillation untreated for 8 min,standard CPR was initiated and 30 animals got ROSC.The ROSC animals were randomly (random number)assigned to normothermia group (n=15 ) and hypothermia group (n =15 ).The hypothermia group immediately received endovascular cooling to regulate temperature to 33 ℃,which was maintained for 12 h,followed by passive rewarming at 0.5 ℃/h to 37 ℃.The two groups were scanned to get Diffusion-weighted imaging (DWI)at baseline (before experiment),6 h,12 h,24 h,and 72 h after ROSC.The statistical analysis was carried out with Student t test,One-way repeated-measures and Kaplan-Meier survival analysis.Results Compared with the normothermia group,the hypothermia group exhibited a higher 72-h survival rate (73.3% vs.40%,P<0.05),lower neurological deficit scores (43.81 vs.119.50;P<0.01),a lesser decrease in the apparent diffusion coefficient during DWI and milder cerebral edema on DWI image. Conclusions Cerebral edema occurred at early stage after ROSC.Cerebral edema was worst at 6 hours after ROSC and then subsided gradually.Hypothermia therapy could reduce cerebral edema and produce a protective effect on neurological function.MRI could effectively reflect the underlying trend of cerebral injury of swine within the first 72 h after ROSC,and demonstrated that hypothermia could reduce brain edema, increase cerebral blood flow,and reduce the production of toxic metabolites.DWI could monitor brain injury after resuscitation and could be used to evaluate the efficacy of hypothermia intervention dynamically.

Objective To investigate the gender differences of coronary heart disease secondary prevention status in patients post percutaneous coronary intervention (PCI). Methods Patients diagnosed with coronary heart disease from 31 tertiary hospitals were enrolled for a baseline survey. Medical history and laboratory tests were taken. Analysis was done for outpatient or inpatient with the history of at least one PCI treatment. Status of smoking cessation, weight management, blood pressure < 140/90 mm Hg, low-density lipoprotein cholesterol (LDL-C) < 100 mg/dL (2.6 mmol/L), and use of antiplatlet drugs, beta-blockers, angiotensin-converting enzyme (ACE) inhibitors/angiotensin receptor blockers (ARB) and statins were collected and compared. Results Women (n=1151) accounted for 25.4% of all PCI patients (n=4532). Proportion of female with history of smoking was signiifcantly lower than male, but the proportion of quitting was similar between female and male, 53%(n=98) vs. 53.7%(n=1344), P=0.849. The average body mass index, mean waist circumference and proportion of overweight were higher in man than women, P=0.000. However, the proportion of abdominal obesity in women is higher than men, 75.2%vs. 52.8%, P=0.000. More female were comorbid with hypertension, hyperlipidemia and diabetes than male and the differences were signiifcant, P=0.000. Control rate of blood pressure, LDL-C and fasting glucose were lower in women than in man, the differences were 66.2% vs 73.4% for blood pressure, 47.8%vs. 57.0%for LDL-C and 57.5%vs. 62.7%for fasting glucose, P=0.000. There was no signiifcant difference in medication usage between different genders. Conclusions In patients post pecutaneous coronary intervention, female patients had more risk factors than male while risk factor control rate was lower comparing with male. Medication usage for coronary heart disease secondary prevention was similar between different genders.

Objective: To investigate the expression of chemokine like factor 2 (CKLF2) mRNA in the rat myocardium after myocardial infarction(MI).Methods: In a rat model of MI, the myocardium surrounding the infarcted area was used for RNA preparation at different time points. After RT, competitive polymerase chain reaction amplification was performed to assess the expression of rCKLF2 mRNA. SAS Kruskal Wallis test was used for statistical comparisons. Results: The gene expression of rCKLF2 at mRNA level was significantly increased in the myocardium surrounding the infarcted area 3 days, 1 week, 2 weeks after infarction.Conclusion: It is possible that CKLF2 contributes to the pathophysiological process and needs to be further investigated.
