During the past few years, it was found that hemophiliacs suffered from AIDS increasingly from year to year. The first case of hemophilia with AIDS was found in the fourth quater of 1981. Eight cases of hemophilia occurred in 1982, and 12 cases of AIDS were found in the hemophiliacs in 1983. The goal of this paper was to test the titer of CMV, EBV, HTLV and EA in the blood stream of hemophiliacs. Hemophiliacs had much higher sensitivity to CMV and EBV than the healthy control. There was a significant difference between these hemophiliacs without any symptoms of AIDS and healthy man. The relationship between hemophilia and AIDS and the cause that the hemophiliac suffers from AIDS are discussed.

ObjectiveTo analyze the factors related to the operation treatment effectiveness of lumber intervertebral discprolapse.MethodsThe data of 442 patients with lumber intervertebral discprolapse and treated by operation were analyzed retrospectively.Results442 patients had results of excellent in 319 cases (70.3%), good in 89 cases (20.2%), fair in 27 cases (6%), and poor in 7 cases (3.5%), the rate of re-operation was 2.9% (13 cases).ConclusionThe operation treatment of lumber intervertebral discprolapse must be performed after having precise diagnosis, surgical operation adaptation and suitable operation methods and enhancing nursing and recovery should be taken after operation in order to get a satisfactory effectiveness.

OBJECTIVE:To provide references and suggestions for building and improving the R&D incentive policies for or-phan drugs in China. METHODS:The R&D incentive policies for orphan drugs in USA and the EU were compared in aspects of its legislative history,incentive measures and effects. And suggestions for improving related policies in China were put forward. RE-SULTS & CONCLUSIONS:The R&D incentive policies for orphan drugs in USA and the EU respectively started from Orphan Drug Act in USA(1983)and Orphan Drug Management Specification in the EU(1999),then formed relatively complete system by continuous improvement. The USA and the EU showed differences in its certification standard,procedure and specific incentives [R&D funding,tax deduction,fee reduction,additional incentives for micro and small and medium enterprises (SMEs),market exclusivity and special approval procedure],etc. In terms of fee reduction,for example,prescription application fee,production cost and drug confirmation fee were exempted in USA,while arrangement assist fee,initial and follow-up fee,checking fee before approval,initial listing type were reduced to a certain percentage in the EU. After developing incentive policies for orphan drugs, there is great increase in numbers of recognized qualifications and listing,SMEs have become new force in orphan drug R&D, R&D investment covers all types of diseases,orphan drug R&D are becoming the main direction of drug innovation and biotechnol-ogy development. China should determine the relevant legislation of R&D incentives for orphan drugs as soon as possible,set certi-fication and improve specific measures of R&D incentives for orphan drugs from multiple aspects,while strengthen the cooperation with other countries in qualification and R&D incentives.

Objective To investigate the potential factors which have impact on the working space for surgeons in gasless laparoscopic cholecystectomy and to probe into the specifications of gasless surgeries.Methods Clinical data of 49 cases of gasless laparoscopic cholecystectomy between March 2007 and July 2010 were summarized.The impacts of body mass index,bowel preparation and means of anesthesia on operation time and conversion to laparotomy were analyzed.Results For patients with body mass index ≤25and ＞ 25,operation times were (43.0 ± 5.4) min,and (52.8 ± 7.4 ) min,respectively,and rates of conversion to laparotomy were 0/34 and 4/15,respectively.Both indices in the first group were higher.For patients with and without bowel preparation,operation times were (44.5 ± 5.4) min and (46.1 ± 8.0)min,respectively,and rates of conversion to laparotomy were 2/26 and 2/23,respectively.For patients with epidural anesthesia and lumbar/epidural anesthesia,operation times were (46.5 ± 7.9) min and (44.1 ±6.8) min,respectively,and rates of conversion to laparotomy were 2/24 and 2/25,respectively.Conclusions The operation time of gasless laparoscopic cholecystectomy could be affected by many factors,such as body mass index.Gasless operations can be improved by evaluating the conditions of patients correctly and by selecting suitable operation methods,anesthesia means and bowel preparation.

Objective This study was carried out to reveal the photocatalytic degradation characteristics of Bisphenol A,a representative endocrine disruptor,with immobilized nanometer TiO2 catalyst supported on fiberglass net.Methods The effects of photolysis under black light lamp and cold cathode low-pressure mercury lamp,and initial concentration(0.98-6.23 mg/L) on the degradation of bisphenol A(BPA) was explored by photoreactor in laboratory.Photocatalytic mineralization and intermediates under different irradiations was also investigated.Results It was found that the reaction kinetics was first order with respect to BPA concentration,and the apparent kinetic constants decreased with the increase of initial concentration.Photodecomposition of BPA under black light lamp irradiation was caused by not photolysis but photocatalysis,while that under cold cathode low-pressure mercury lamp was caused by the synergistic effect of photolysis as well as photocatalysis.Further studies showed that photocatalytic mineralization of BPA differed greatly under those different irradiations.1,4-benzoquinone,p-dihydroxybenzene,methyl p-hydroxybenzoate,D-hydroxyacetophehone,1-(4-hydroxyphenyl)-1-propanone,1-(4-hydroxyphenyl)-vinyl alcohol were identified as intermediates under black light lamp,and 3-hydroxyl-3-crotonic acid,4-hydroxybenzaldehyde,D-hydroxyacetophehone,2-acetyl-3-methoxyl-5,8-dihydroxy-1,4-naphthoquinone,3,4-di-(4-hydroxyphenyl)hexane were found under cold cathode low-pressure mercury lamp.Conclusion The differences of photocatalytic mineralization under different illumination are attributed to the molecule structure with two benzene-rings.
