Biotrickling filter often offers a cost effective and environmentally friendly alternative to conventional air pollutant control technologies,but major problems with clogging of the filters due to a high biomass accumulation will provent it from the industried uses.In this paper,the effect of the high biomass accumulation in an air pollution treatment with a biotrickling filter is discussed.Two parameters with specific surface area with biofilm growth(?_ f ) and the bed porosity with biofilm(?_ f )are used to analyse its principle of accumulation.Finally,some control measures including chemical methods,physical machine-made methods and other control methods are overviewed.

Objective To investigate the clinical effectiveness of coronary artery bypass grafting through descending thoracic aorta in elderly patients with coronary heast disease and to decrease the post-operative complication.Methods Thirteen elderly patients underwent coronary bypass surgery with minimally invasive direct coronary artery bypass (MIDCAB).Age range from 70 to 82 years with a mean of(72.1?6.0)years.Patients suffered from multi vessel disease.Many minimally invasive techniques of“Y”blood vessel graft anastomosis,anastomosis of blood vessel graft to descending aorta,minimally invasive direct,thoracoscope assist were used.Results All patients were survived.The mean duration of intubation was (6.9?0.9) hours.The average ICU stay was (2.5?0.5)days.No patients received blood transfusion.During the short-term follow-up(3 to 14 months) patients had no complaint of angina,Conclusions The technique of“Y”blood vessel graft anastomosis,descending aorta blood vessel graft,minimally invasive direct and thoracoscope assist in combination with coronary artery bypass grafting is a safe and cost-effective new procedure for elderly patients with multi-coronary artery disease.

Objective To study the expression of p73 in human non-small cell lung cancer (NSCLC) and the relationship between p73 expression and clinico-pathological parameters. Methods Expression of p7 3 gene was detected by RT-PCR in 32 human NSCLC tissues, tissues adjacent to ca ncer and non-cancer lung tissues. Results p73 gene expression up-regulated substantially and detected in 87.5%(28/32) of human NSCLC tissues while expressed at low level in tissues adjacent to cancer and non-cancer lung tissues. Conclusion Marked up-regulation of p73 gene expres sion is found in human NSCLC.

Objective To sum up the therapeutic results of 125 cases of tetralogy of Fallot(TOF),and ex- plore the optimal time and risk factors of opration,as well as perioperative management.Methods One hundred and thirth-one consecutive cases of TOF underwent corrective surgery.There were simple stenosis of infundibular portion in right ventricular outflow tract in 37 cases,stenosis of infundibulum and pulmonary valve in 14 cases,main pul- monary trunk and left/right pulmonary arteries stenosis in 74 cases,and pulmonary atresia in 5 cases.Autologousper- icardial conduit,or with waived were used for right ventricular outflow tract and right ventriculo-pulmonary artery connection.Other anomalies were corrected.Results The surgicalmortality was 4.0 %.The cause of death were se- rious low cardiac output syndrome(3 patients),respiratory function failure(1 patient),pericadial infection(1 pa- tient).Conclusion It is necessary to profonn corrective opration on younger TOF patients.Effetive prophylaxis and control of low cardiac output syndrome and pulmonary complication is a useful strategy.

OBJECTIVETo understand the hereditary and variant characteristics of rubella virus(RV), especially the strains isolated from China, investigating the epidemical trend and variation principle of RV.
METHODSThe envelope glycoprotein E1 gene was amplified from rubella virus by RT-PCR. After sequencing, the gene sequence was handled by the software DNASTAR and the phylogenetic tree was drawn to analyze the molecular epidemiological characteristics of RV.
RESULTSThe sequence of RV strain JR23 was sequenced, the phylogenetic tree was drawn taking 30 strains isolated at different times and locations in GenBank, including three strains from China as reference. The regions that encode the peptides which react with the HI antibody and the neutralization antibody were compared to show if there was any amino acid mutation in the sequence. (1) In general, the nucleotide and amino acid sequences of RV were highly conserved. The four strains isolated from China had relatively large variations. Strain 379 and strain BRD constituted genotype II, which is different from the other 29 strains. Further study is needed to understand their heritable resources and biological characteristics. (2) Strain JR23 showed little difference from the strains that were epidemic during 1960s in UK, USA and Japan, so maybe it is the derivative strain of that in epidemic 1960s. But the accurate epidemic time is not known.
CONCLUSIONThere are differences among areas and time in epidemics of rubella. The mobility and the region difference seem to be the key factors that affect the epidemic characteristics of RV.

Guanylate-binding protein 1 (GBP1) is an interferon induced protein, that belongs to the guany late-binding protein family. GBP1 is widely involved in anti-infection immune responses, anti-tumor activity and various biological reactions. Recent studies have proved that IFN-alpha, IFN-beta, IFN-gamma, IL1alpha, IL1beta, TNF-alpha and LPS can induce GBP1 expression; hence, the diverse biological functions of GBP1 have been gradually deduced and exploited. Many studies have been performed over recent years to understand the exact mechanisms that underlie the anti-infection and anti-tumor properties of GBP1. This review describes the molecular structure, biological activity, anti-infective properties and other functions of GBP1, in order to provide insights into the divergent roles of GBP1 in the regulation of various biological processes.

OBJECTIVETo explore the effects of three Chinese herbal antidotes, i.e. Herba Artemisiae annuae (A), Herba Hedyotis diffusae (H) and Rhizoma Cimicifugae (C), all were ingredients of Jiedu Quyu Ziyin Recipe, for adjusting the regulated on activation normal T cell expressed and secreated (RANTES), gene expression in serum and renal tissue of MRL/lpr mice.
METHODSFifty-four MRL/lpr mice were randomized into 9 groups, with 6 in each, and intragastrically infused with A, H, C, A+H, H+C, A+C, A+H+C (all in dosage-form of decoction), prednisone suspension and physiological saline, respectively for 12 weeks. RANTES expression in serum and renal tissue of animals were detected with ELISA and RT-PCR at the end of the study.
RESULTSLevels of RANTES expression was significantly reduced in the prednisone treated group after treatment. Excepting no significant change being observed in the groups treated with A and C, the changes in the other groups were all milder than those in the group treated with A+H+C.
CONCLUSIONChinese herbal antidotes A, H and C in combination can significantly inhibit the RANTES expression in serum and renal tissue of MRL/lpr mice.
