Objective To select valuable biomarkers for diagnosis and predicting outcome of sepsis-related acute respiratory distress syndrome(ARDS) from D-dimmer (DD),yon Willebrand factor (vWF),platelet (PLT),N terminal-pro brain natriuretic peptide (NT-ProBNP),interleukin-6 (IL-6),interleukin-8 (IL-8) and surfactant protein D (SP-D).Methods A total of 48 sepsis accompanied with ARDS patients and 40 sepsis patients were prospectively studied with comparison.The clinical characteristics of all the patients were recorded in detail.The blood samples were obtained within 24 hours of ICU admission.The concentration or activity of the seven biomarkers was quantitatively assayed and the results were recorded.To select the most valuable biomarkers as clinical indices,diagnosis model and death predictive model were constructed by Logistic regression.Results Among the seven candidate biomarkers,SP-D,vWF and IL-8 showed the most value.Their area under the receiver operator characteristic curve (ROC) were 0.758 (P ＜ 0.01),0.783 (P ＜ 0.01) and 0.747 (P ＜ 0.01) respectively,and raised to 0.847 (P ＜ 0.001) when the three biomarkers were combined.IL-8,age greater than or equal to 60 years and APACHE Ⅱ score greater than or equal to 20 were related to ARDS death with 12.138(lnIL-8)(P=0.022),6.157(P=0.040) and7.415(P=0.014) of OR values respectively.Conclusion SP-D,vWF,IL-8 should be valuable for early prediction of sepsis-induced ARDS and the diagnostic accuracy raised through combined utilization.IL-8 may be predictable for prognosis of sepsis related ARDS and the comprehensive evaluation combining clinical indices with IL-8 should be suggested in clinical practice.

Objective: To apply the NRS2002 to screen the nutritional status of preoperative patients and investigate the nutrition support in the perioperation and clinical outcomes. Methods: 127 selective operational cases(including general surgery,thoracic surgery,gynecology and orthopedic) were recruited to adopte the NRS2002 which issued by CESPN in 2006,and the nutrition support,energy and nutriment in the perioperation,complications,length of stay and drug costs were investigated. Result: 30.7% patients needed nutrition support,with general surgery(28.3%) being higher than thoracic surgery(2.4 %),gynecology(0%) and orthopedic(0%).The nutritional risk in elderly,carcinoma,abdominal operation patients were 18.1%,19.7% and 18.1% seperately,which was higher than others(P

The concentrations of berberine (BBR) and 8-cetylberberine (8-BBR-C16) in rat plasma and tissue were determined by RP-HPLC. Both the plasma pharmacokinetics characteristic and tissue distribution differences of BBR and 8-BBR-C16 were compared to provide experimental data for the mechanism research and further drug development. After the oral administrations of BBR and 8-BBR-C16 at the dose of 80 mg x kg(-1) for rats, the pharmacokinetics result showed that compared with BBR, the C(max) and AUC(0-t), of 8-BBR-C16 increased by 2.8 times and 12.9 times respectively, t1/2 extended from 3.61 h to 11.90 h. The tissue distribution result showed that compared with BBR, the concentration of 8-BBR-C16 in various organizations increased and the retention time extended remarkably. The maximum concentration was achieved in lung and the highest concentration in it was 3 731.82 ng x g(-1). After being derived, the C(max) in plasma and bioavailability of 8-BBR-C16 increased remarkably and the circulation time in vivo extended. The drug concentration in tissue increased remarkably, and the distribution ratio changed too, with strong targeting selection in lung.

OBJECTIVETo compare the differences in clinical efficacy on peripheral facial paralysis at acute stage between the opposing needling technique and routine acupuncture at the affected side so as to provide the evidence on the acupuncture treatment for peripheral facial paralysis at acute stage.

METHODSForty patients were rando- mized into an opposing needling technique group (19 cases) and an affected side needling technique group (21 cases). The basic medication was same in the two groups. The acupoints were Fengchi (GB 20), Yangbai (GB 14) to Yuyao (EX-HN 4) (penetrating needling method), Jingming (BL 1), Chengqi (ST 1), Xiaguan (ST 7), Jiache (ST 6) to Dicang (ST 4), Hegu (LI 4) and Zusanli (ST 36). In supplementation, in the opposing needling technique group, the acupoints were stimulated on the face of healthy side. In the affected side needling technique group, the acupoints were stimulated on the face of the affected side. The treatment was given three times a week, for 4 weeks. House-Brackmann (H-B) facial nerve function assessment was used to evaluate facial nerve function before and after treatment in the patients of the two groups. The efficacy was compared between the two groups.

RESULTSThe facial nerve function was recovered in the two groups and the total effective rate was 100.0% in the two groups (P>0.05). The curative rate was 68.4% (13/19) in the opposing needling technique group and better than 47.6% (10/21) in the affected side needling technique group (P<0.05). On the 7th and 14th day, scores of H-B in the opposing needling technique group were better than those in the affected side needling technique group (both P<0.05). The curative time in the opposing needling technique group was apparently shorter than that in the affected side needling technique group ((23.95 +/- 4.30) days vs. (29.14 +/- 5.43) days, P<0.01).

CONCLUSIONThe opposing needling technique accelerates the recovery of facial nerve function in peripheral facial paralysis at acute stage and apparently shortens the curative time. The efficacy is better than that in acupuncture on the affect- ed side of the face.

OBJECTIVETo explore the mechanism of acupuncture combined with medication for treatment of essential hypertension (EH).

METHODSSixty cases of EH were randomly divided into a combined acupuncture and medication group (group A) and a medication group (group B), 30 cases in each one, treated with acupuncture in combination with oral administration of Felodipine, and simple oral administration of Felodipine respectively. Before and after treatment, the changes of blood pressure, and the contents of E-selectin (Es), iNOS and eNOS were determined.

RESULTSAfter treatment, the blood pressure declined in either group. The total effective rate in group A was 86.7% (26/30), which was superior to that of 73.3% (22/30) in group B. After treatment, the plasma Es and iNOS contents in two groups decreased as compared with those before treatment (both P < 0.01), of which, plasma Es content in group A decreased apparently as compared with group B (P < 0.01). After treatment, the content of plasma eNOS increased as compared with that before treatment in group A (P < 0.01).

CONCLUSIONThe mechanism of acupuncture on anti-blood pressure probably relies on the improvements in vascular endothelial cellular function so that Es, iNOS and eNOS expression can be recovered to normal level and ultimately blood pressure is adjusted.

ObjectiveTo investigate the effects of protein phosphatase 2A (PP2A) inhibitors on the viability of pancreatic cancer cell line PANC-1 and its mechanism.MethodsPANC-1 cells were treated with PP2A inhibitors Cantharidin or Okadiac acid.The activity degree of NF-κB pathway was tested by Western blot.NF-κB pathway was blocked from all sectors by PP2Acα plamid transfection,NF-κB inhibition of protein kinase α (IKKα) and NF-κB inhibitor α (IκBα) dominant negative mutant and p65 interfering plasmid.Cell viability was determined by MTT.ResultsPP2A inhibitors could induce phosphorylation of IKKα,further phosphorylation of IκBα and degradation and followed by the release of p65 into nucleus.When PP2Acα,IKKα dominant negative mutant and IκBα dominant negative mutant were overexpressed,or p65 was interfered,the inhibition rate of Cantharidin on cell viability decreased (31.85±13.37) ％,(23.48±8.98)％,(22.63±5.81)％ and (20.88±3.24)％respectively,and the inhibition rate of Okadiac acid on cell viability decreased (40.17 ± 11.65)％,(27.34±14.28)％,(24.85±3.39)％ and (27.08±3.81)％ respectively.ConclusionsPP2Ainhibitors play a role in preventing pancreatic cancer through PP2Acα/IKKα/IκBα/p65 pathway.

Purpose To investigate the relationship between Epstein-Barr virus (EBV) and lymphoepithelioma-like carcinoma (LELC) of the parotid gland and detect the gene expression products of EBV harbouring in LELC cells. Methods Thirty-two parotid LELCs were collected from the Departments of Pathology, Sun Yat-sen University of Medical Sciences, Guangzhou, China during the period of January 1986 and December 1995. All the 32 formalin-fixed paraffin-embedded blocks had been consecutively re-sectioned again. Immunohistochemical and in situ nucleic acid hybridization methods for detection of EBV gene encoded products were performed. Results (1) 32 LELCs were found out of 125 parotid gland carcinomas, the frequency was 25.6% (32/125). (2) All of the 32 specimens contained a variable number of EBNA-1 and EBERs positive neoplastic cells. (3) Twenty-seven out of 32 specimens (27/32, 84.4%) had a portion of carcinoma cells expressing LMP-1. (4) No ZEBRA positive cell could be found. (5) EA-D, VCA and MA positivity rates for these 32 parotid LELCs reached to 71.9%(23/32), 68.8%(22/32), and 12.5%(4/32), respectively. Conclusions (1) The parotid gland LELC is frequently to be seen in Guangzhou locale of China, where is a high-incidence area of nasopharyngeal carcinoma (NPC). The parotid gland LELC and NPC are co-prevalent in Guangzhou locale. (2) This disease is also consistently associated with EBV infection. (3) The EBV infection of the parotid gland LELCs is essentially the type of latency Ⅱ, expressing EBNA-1, EBERs and LMP-1. (4) The latent infected EBV harbouring in LELC cells could in part be switched over to lytic cycle, producing EA-D, VCA or/and MA.
