Objective To assess the diagnostic value of apparent diffusion coefficient (ADC) in the classification of solid nodules of brain parenchymal tuberculosis and response evaluation of patients.Methods Brain parenchymal lesions of 128 patients,with clinically and (or) pathologically confirmed brain parenchymal tuberculosis were analyzed retrospectively.Results Significant differences were observed in the average ADC values between enhanced areas and edematous areas of homogeneously enhancing and ring-enhancing lesions in all 128 patients before treatment(P<0.05).In 52 patients, the average ADC values of enhanced areas and edema areas in homogeneously enhancing and ring-enhancing lesions were significantly different before and after the treatment(P<0.05).Conclusion The ADC values in different areas of solid nodules of brain parenchymal tuberculosis are different, so can be used as a supplement to magnetic resonance imaging diagnosis and classification.After anti-tuberculosis treatment, the ADC values can be used as an observational indicator in follow-up.

Objective To observe the changes of urinary microalbumin(UMA),and explore the relation between early impairment of renal function and level of UMA in patients with obstructive sleep apnea hypopnea syndrome(OSAHS).Methods OSAHS patients(n=67)and healthy control subjects(n=82).Then body parameter,serum creatinine(SCr),blood urea nitrogen(BUN),glomerular filtration rate(GFR)and UMA were determined in both groups.Furthermore,linear correlation was performed between UMA and body parameter,SCr,BUN,GFR and sleep-breathing parameters of patients with OSAHS,respectively.Results UMA level was higher in OSAHS patients than that in control subjects(P＜0.01).UMA level in OSAHS patients was correlated positively with body mass index(BMI),apnea hypopnea index(AHI),percentage of sleep time below 90% oxygen saturation (SaO2＜90%)and percentage of sleep time the total duration of apnea/hypopnea,respectively,and those were correlated negatively with the lowest SaO2 and the average lowest SaO2 respectively,but those had no correlativity with age,stature,waistline,neckline,SCr,BUN and GFR(P＞0.05).Conclusions UMA level increases in patients with OSAHS.The detection of microalbumin in urine is helpful in early diagnosis in OSAHS renal damage patients.

AIM: To study the regulatory effect of curcumin on expression of heme oxygenase-1 (HO-1) in the lung of rat treated with LPS. METHODS: Eighteen rats were divided into three groups injected with different agents via lingua vein: control group (animals received equivalent saline) , LPS group (animals received a bolus dose of LPS 5 mg?0.5 mL-1?kg-1) and LPS+ curcumin group (animals received AP- 1 inhibitor curcumin 20 mg?0.5 mL-1?kg-120 min before the injection of LPS 5 mg ?0.5 mL-1?kg-1) . The expression of HO-1 mRNA and protein in the lung were examined 7 h after LPS administration by reverse transcribed polymerase chain reaction (RT- PCR) and Western blotting, respectively. Carboxyhemoglobin (HbCO) formation within pulmonary tissue was measured to represent CO content. RESULTS: The results showed that HO- 1 mRNA and protein expression as well as CO content in the lung of rats in LPS group were significantly higher than those in control group (P

OBJECTIVE To observe the controlled hypotensive effect of remifentanil in patients of different age groups undergoing FESS. METHODS Forty-seven ASAI-II patients were divided into two groups: young-middle aged group(18～55yr,n=24)and elderly group(60～72yr,n=23). Both groups received remifentanil by continuous infusion. Their systolic blood pressures (SBP) were reduced to 30～35 % of the base values and sustained throughout surgery. SBP,diastolic blood pressure (DBP) and heart rate (HR) were monitored throughout surgery. The surgical field quality score, total dose of remifentanil and postoperative complications of each patient were recorded after the operation. RESULTS The SBP and DBP of two group were reduced to the target pressure at the beginning of the operation(P0.05). CONCLUSION Remifentanil enabled controlled hypertensions and offer superior surgical field conditions for FESS in patients of different age groups. Moreover,it was a more suitable alternative for elderly patients because HR did not increase during controlled hypotension.

BACKGROUND:After cerebral tissue ischemia and anoxia in young rats,the cerebral edema gets serious, and the levels of nitric oxide (NO) and malondialdehyde (MDA) decrease. Radix Astagali seu Hedysari has the pharmacological effects of enhancing immunity, anti-anoxia and improving myocardial ischemic reinfusion injury.OBJECTIVE: To investigate the influences of Radix Astagali seu Hedysari (huangqi) on contents of NO and MDA in brain tissue of young rats with cerebral injury after cerebral ischemia and anoxia.DESIGN:A randomized and controlled trial.SETTING: Department of Pediatrics, Second Hospital, Hebei Medical University; Department of Internal Medicine, Institute of Traditional Chinese Medicine, Hebei Medical University; Department of Pathophysiology, Hebei Medical UniversityMATERIALS:The experiment was conducted from January to April 2004at Department of Pathophysiology, Hebei Medical University. Total 40 SD rats, 7-day old, were at random divided as normal control group, model group, humgqi low-dose group and huangqi high-dose group, with 10 rats in each group. Huangqi injection (The content in 10 mL injection is consistent with 20 g raw drug) was provided by Institute of Traditional Chinese Medicine of Hebei Medical University (produced in Chengdu Di'ou Jiuhong Pharmaceutical Factory, Batch No. 0005028).METHODS:Except rats in normal group, those in the rest groups, under conscious and local anesthesia, were all given common carotid artery ligation, establishing cerebral injury model due to ischemia and anoxia. Rats in normal group were intraperitoneally injected 0.1 mL normal saline; rats in model group were intraperitoneally injected 9 g/L normal saline, 0.1 mL each day; rats in huangqi low-dose group and huangqi high-dose group were respectively given 0.1mL, 0.5 mL huangqi injection, once a day, intraperitoneally. Cerebral blood flow was detected immediately, 2 and 4days after injection. Then the rats were decapitated for collecting the brains to measure the water content in brain, the contents of NO and MDA.MAIN OUTCOME MEASURES: [1] Water contents in brains of rats in every group. [2] Cerebral blood flow, and the contents of NO and MDA.RESULTS:Totally 40 rats were involved in the trial and all entered in the final result analysis. [1] The water content in brain of each group: Compared with normal group, the content in model group was increased immediately after model establishment [(87.316±0.275)%, (88.259±0.297)% ,P ＜ 0.05 ],and did not return to the normal level at the second day [(86.973±0.265)%,(88.173±0.445)%,P ＜ 0.05]; compared with model group, the content in huangqi high-dose group was obviously decreased at second day[(88.173±0.445)%, (86.542±0.141)% ,P ＜ 0.05]. [2] Measurement of cerebral blood flow: compared with control group, the blood flow in model group was obviously decreased immediately after model establishment[(231.88±13.33), (139.54±10.58)mV,P＜ 0.05], and did not return to normal level till the 4th day [(234.57±14.38), (145.38±13.33)mV,P ＜ 0.05];compared with model group, the blood flow in huangqi low-dose group and huangqi high-dose group, at day 4, was obviously increased [(145.38±13.33),(288.45±12.89), (313.82±21.74)mV,P ＜ 0.01]. [3] The contents of NO and MDA: The contents in model group, immediately after model establishment, were obviously higher than those in normal control group [(26.55±5.23 ), ( 19.67±7.17 )μmol/L,P ＜ 0.05; (7.88±2.55), (4.22±0.12) μmol/L, P＜ 0.01], and at day 4, were significantly higher than those in normal control group [(48.65±17.06), (18.65±2.12)μmol/L,P ＜ 0.01; (5.29±0.68),(4.06±0.39)μmol/L,P ＜ 0.05]; compared with model group, the contents in huangqi low-dose group and huangqi high-dose group were obviously decreased at day 4 [(48.65±17.06), (23.77±12.79), (24.67±11.54)μ mol/L,P＜ 0.01; (5.29±0.68), (4.51±2.30), (3.68±0.39)μmol/L,P ＜ 0.01].CONCLUSION:Huangqi could obviously reduce cerebral edema from ischemia and anoxia, increase cerebral blood flow. It could decrease the contents of NO and MDA that is metabolite of free radical injury, thus playing its role to inhibit lipid peroxidation injury.

Objective To investigate the effect of percutaneous eoronary intervention (PCI) on the prognosis of acute ST-segment elevation myocardial infarction (ASTEMI) in the elderly.Methods The 1318 ASTEMI patients in our hospital from June 1998 to June 2008 were retrospectively analyzed. Among them, 338 (25.6%) elderly patients were over 60 years old, and 316patients consistent with inclusion and exclusion criteria were consecutively enrolled in our research.Then they were divided into two groups: PCI group (136 cases, 43.0%) and conservative drug treatment group (180 cases, 57. 0%). The clinical data of study objects were collected. Then they were followed up regularly for two years. Results There were no statistically significant differences between the two groups in mean age, gender, hypertension, diabetes, dyslipidemia, excess smoking,wine and family history (all P＞ 0.05). And there were no statistically significant differences in anterior wall STEMI, Killip Ⅲ-Ⅳ class, thrombolysis therapy and malignant ventricular arrhythmia (all P＞0. 05). Most of the objects proceeded therapeutic lifestyle improvements, such as giving up smoking, restricting wine, regulating diet, losing weight and insisting on exercises, and so on.Secondary prevention drugs of acute myocardial infarction including angiotensin converting enzyme inhibitor, angiotensin receptors blockers, beta receptor, aspirin and statins were regularly administrated in the two follow-up years. In the retrospective research, incidence rates of reinfarction, NYHA (New York Heart Association) Ⅲ-Ⅳ class heart function and one-month mortality were much higher in conservative treatment group than in PCI group (17.2% vs. 2. 2%, OR=9. 224,95% CI: 2. 756-30. 857; 31.1% vs. 8.1%,OR=5.132, 95%CI: 2. 568-10. 257; 8. 3% vs. 1.5%,OR= 6. 091, 95% CI: 1. 369-27. 105, respectively; all P ＜ 0. 01). Above all, one and two-year mortalities were much higher in conservative treatment group than in PCI group (21.1% vs. 2. 2 %,OR=11.864, 95%CI: 3.577-39.349; 32.2% vs. 4.4%, OR=10.301, 95%CI: 4.289-24.736,respectively; all P＜0. 01). Conclusions PCI may reduce the re-infarction, NYHA Ⅲ-Ⅳ class heart function and one-month mortality, especially so in view of the one and two-year mortality. PCIcan significantly improve the prognosis of ASTEMI in the elderly.
