OBJECTIVETo explore potency material bases of Xuebijing (XBJ) formula, and to analyze its effects at the molecular network level.

METHODSTotally 16 sepsis-related targets were selected and classified into three categories such as inflammation, immune, and coagulation referring to biological roles. Then molecular database of chemical compositions in XBJ formula were constructed to explore mutual actions with inflammation, immune, and coagulation targets.

RESULTSDanshen root and safflower, with more effector molecules with immune and coagulation targets, have extensive anticoagulation and anti-inflammation effects. The former 10 molecules with better mutual actions with sepsis targets were sequenced as tryptophane, danshensu, gallic acid, salvianolic acid D, protocatechuic acid, salvianolic acid A, danshensu C, vanillic acid, rosmarinic acid, phenylalanine. There existed two phenomena in XBJ formula as follows. One component had stronger actions with multi-targets, for example, danshensu had actions with 13 targets. Meanwhile, different components acted on the same target protein, for example, 8 molecules acted with MD-2.

CONCLUSIONXBJ formula had certain potential synergistic effects with sepsis targets, which could provide certain referential roles for findina new type anti-septic drugs.

ObjectiveTo explore the effects of ziprasidone and risperidone on cognitive inhibition function through visual pathway of patients with paranoid schizophrenia.MethodsIn the open-label,flexible-dosage trial,124 patients with paranoid schizophrenia were randomly divided into ziprasidone group (120-160 mg/d)and risperidone group(4-8 mg/d) for treatment of 8 weeks.They were assessed with computerized Color Word Test (CWT) and Continuous Performance Test(CPT) through visual pathway for cognitive inhibition function,Positive and Negative Syndrome Scale for efficacy on baseline and 8th weekend.ResultsAfter treatment with ziprasidone,the error number (3.12 ± 5.23 ),the time per correct answer( ( 1.92 ± 1.38 ) s) of CWT,as well as the doubledigit mistaken number (2.31 ± 3.76)and the three-figure mistaken number( 3.15 ±2.80) of CPT reduced more than those before medication ( (4.60 ± 6.80),( 2.74 ± 1.52 ) s,(3.85 ± 3.62 ),(4.42 ± 3.53 ) ) (P ＜ 0.05 ).In risperidone.group,the double-digit mistake number of CPT(3.39 ± 3.59) after pharmacotherapy reduced more than that before pharmacotherapy(4.23 ± 3.88) (P＜ 0.05).After treatment the time per correct answer of CWT and the mistaken numbers of CPT in ziprasidone group were less than those in risperidone group(P＜ 0.05 ),meanwhile,the scores of PANSS in two groups were significantly lower than those before treatment (P ＜ 0.01 ).ConclusionIt is effective for ziprasidone and risperidone to improve the function of cognitive inhibition on patients with paranoid schizophrenia,but there is more dramatic for ziprasidone in short-term treatment.

Objective To investigate the clinical value of proximal femoral nail antirotation ( PFNA) in treatment of intertrochanteric fractures.Methods From April 2007 to July 2009,112 patients with intertrochanteric fractures were treated by using PFNA.There were 34 males and 78 females,at mean age of 76 years.Of all,80 patients were with type 31-A2 fracture and 32 with type 31-A3 fractures according to AO classification.According to Singh index classification,there were 4 patients at grade Ⅰ,21 at grade Ⅱ,70 at grade Ⅲ and 15 at grade Ⅳ.The fracture was caused by low-energy injury in 97 patients and by high-energy injury in 15.The Salvati-Wilson score was used to evaluate the hip function postoperatively.Results Ninety patients received 12-24 months follow-up (average 18.6 months).The Salvati-Wilson score was (29.98 ± 5.18 ) points.The result was excellent in 41 patients,good in 40,fair in 6 and poor in 3,with excellenct rate of 90％.The introduction of the nail in operation was difficult in 22 patients,of which 3 patients suffered femoral cortex rupture.Displacement or separation of the fracture segments occurred in 34 patients and distal locking difficulty in nine during the screw blade tapping process.Local complications included hip pain in 21 patients,thigh pain in 4,apparent coxa vara in 2 and delayed healing in 7.There were no cutting-out or femoral shaft fractures no matter what type of Singh index was.The systemic complications included cardiovascular and cerebrovascular disease in one patient,pulmonary infection in four,deep vein embolism in one and perineum congestion or swelling in seventeen.Conclusion PFNA is effective in treating intertrochanteric fractures especially osteoporotic fractures,but delayed healing of the fractures and the mismatch between the intramedullary nail and the proximal femoral morphology remain to be addressed.

BACKGROUNDTo evaluate the activity and toxicity of paclitaxel as second-line treatment for advanced non-small cell lung cancer (NSCLC).

METHODSForty patients with recurrent advanced NSCLC were enrolled. Thirty-six patients were managed with regular regimen. Paclitaxel 135 mg/m², 3 h, on day 1; DDP 75 mg/m² or carboplatin 300-350 mg/m² on day 2. Four patients were managed with weekly regimen. Paclitaxel 60 mg/m²,3 h, on days 1,8,15; DDP 75 mg/m² on day 2. It was repeated every three or four weeks, up to two to four cycles.

RESULTSThirty-six cases were evaluated for response and 27 for survival. The objective response rate was 13.9% (5/36). At least one tumor-related symptom relief was observed in 21 patients (58.3%). The median survival duration was 26.4 weeks and 1-year survival rate was 8% (4/36). The main toxicities included myelosuppression, fatigue and myalgia-arthralgia neuropathy.

CONCLUSIONSPaclitaxel has advantage to be well-tolerated and improve tumor-related symptom. Further studies with standardization of dose and regimen will be needed to clarify its role in the second-line treatment.

OBJECTIVETo study the loss of heterozygosity (LOH) on chromosome 3p in breast cancers and precancerous lesion.

METHODSLOH at 11 microsatellite loci was detected in 41 cases of breast cancers and 12 cases of precancerous lesion by polymerase chain reaction and silver stain. The expressions of ER, PR, FHIT and hMLH1 were detected in breast cancer by immunohistochemistry.

RESULTSLOH on 3p was detected in 97% of breast cancers. D3S1295, D3S1029 and D3S1038 located at 3p14, 3p21-p22 and 3p25 were identified as the loci with most frequent LOH (53.1%, 43.6% and 52.5%). LOH of D3S1038 and expression of hMLH1 protein correlated with several clinicopathological features. LOH of D3S1295 had significant negative correlation with the expression of FHIT. In breast precancerous lesions, LOH on 3p was detected in 41.7% lesions. D3S1295 and D3S1029 were also identified as the most frequent LOH locus (27.3% and 16.7%). The smallest common LOH region seems likely lie between 3p14 and 3p25.

CONCLUSIONSThe smallest LOH region indicates the existence of breast tumor related genes and some of them affect gene expression.

OBJECTIVESTo analyze the relationship between oxidized low density lipoprotein (oxLDL), angiogenesis and stabilization of atherosclerotic plaques in human coronary arteries; and to investigate the role of oxLDL in creating vulnerable sites in atherosclerotic plaques.

METHODSSamples of coronary arteries were obtained at autopsies of 42 patients with acute coronary syndrome. Eighty randomly selected blocks were studied by immunohistochemistry using antibodies against oxLDL and endothelial cells (factor VIII). Computer-aided planimeter was used for quantitative analysis.

RESULTSIn unstable plaques, percentage of immunoreactive areas for oxLDL was significantly higher than that in stable plaques. Most of the oxLDL were located in shoulder region of these plaques, as compared to the fibrous cap and basal regions. The details of distribution of oxLDL were as follows: shoulder region (20.43 +/- 3.12 for unstable plaques and 17.65 +/- 4.22 for stable plaques), fibrous cap (4.77 +/- 2.03 for unstable plaque and 2.80 +/- 0.22 for stable plaques) and basal region (5.65 +/- 1.65 for unstable plaques and 3.22 +/- 1.02 for unstable plaques). OxLDL was also a main component in the lipid core. In the shoulder region, there was a significant positive correlation between neovascularization and oxLDL (r = 0.8247, P = 0.000).

CONCLUSIONSThe amount of oxLDL is significantly higher in unstable atherosclerotic plaques, especially over the shoulder region. OxLDL in coronary atherosclerotic plaques is thus an important factor in determining stabilization of the plaques. OxLDL may induce influx of inflammatory cells which subsequently leads to decreased plaque stabilization.

Brain magnetic resonance imaging (MRI) of the elderly often reveals white matter changes (WMCs) with substantial variability across individuals.Our study was designed to explore MRI features and site-specific factors of ischemic WMCs.Clinical data of consecutive patients diagnosed with ischemic cerebral vascular disease who had undergone brain MRI were collected and analyzed.Multi-logistic regression analysis comparing patients with mild versus severe WMCs was performed to detect independent associations.Analyses of variance (ANOVAs) were used to detect regionally specific differences in lesions.We found that lesion distribution differed significantly across five cerebral areas,with lesions being predominant in the frontal lobe and parieto-occipital area.To explore WMCs risk factors,after adjusting for gender,diabetes mellitus,and hypertension,only age (P＜0.01),creatinine (P=0.01),alkaline phosphatase (ALP) (P=0.01) and low-density lipoprotein cholesterol (LDL-C) (P=0.03) were found to be independently associated with severe WMCs.Age (P＜0.001) was strongly associated with WMCs in the frontal lobe while hypertension was independently related to lesions in the basal ganglia (P=0.048) or infratentorial area (P=0.016).In conclusion,MRI of WMCs showed that ischemic WMCs occurred mostly in the frontal lobe and parieto-occipital area.The infratentorial area was least affected by WMCs.Typically,age-related WMCs were observed in the frontal lobes,while hypertension-related WMCs tended to occur in the basal ganglia and infratentorial area.
