In vitro cellular adherence of murine neutrophils (Neu), macrophages (Mo) and eosinophils (Eos) to infective larvae (L3) of periodic Brugia malayi was promoted by immune serum (AIMS) or fresh normal mice serun (fNMS). Mo and Neu were more potent than Eos . in killing the L3. Eos could adhere to the L3 in the presence of AIMS or fNMS but a weak cy-totoxic effect was observed only when AIMS was used. The activity in AIMS could be removed with Staphylococcus aureus containing Protein-A (SPA) or anti-mice IgG antiserum suggesting that IgG might be in the observed cytotoxicity. Immunofluorescent staining revealed IgG binding to the surface of L3 after incubation with AIMS. Heat treatment of AIMS at 56℃ 30 min resulted in a reduced cytotoxic effect suggesting the role of complement in the reaction. EDTA but not EGTA abolished this activity indicating the operation of complement by alternate pathway. Scanning electron microscopic (SEM) studies comfirmed that the celluar adherence resulted in gross surface damage to the infective larvae.

OBJECTIVE:To provide reference for the perfecting of hospital information system (HIS) on drug control. METHODS: The problems encountered in using two drug control systems in our hospital were analyzed, and the constructive suggestions on its improvemen was put forward. RESULTS & CONCLUSIONS: The new HIS should be designed to overcome the weaknesses of the current HIS in code design, assignment of authority limit, drug application and dispensing, drug stocktaking so as to make full use of the merit of the computer management.

OBJECTIVE:To summarize the method and experience of clinical pharmacist participating in pharmaceutical care for a case of refractory class Ⅳ+Ⅴ lupus nephritis (LN). METHODS:Clinical pharmacists and physicians formulated individualized treatment together,i.e. prednisone 30 mg/d+MMF 0.5 g,q12 h+FK506 1 mg,q12 h;on the fifth day of treatment,the patient suf-fered from ardent fever and increase of blood pressure,and clinical pharmacist suggested using linezolid 0.6 g,ivdrip,q12 h+merope-nem1.0 g,ivdrip,q8 h to control pulmonary infection;using Amlodipine besylate tablet 5 mg,po,qd+one Valsartan hydrochlorothia-zide capsule, po,qd+Arotinolol hydrochlorid tablet 10 mg,po,bid to control blood pressure. RESULTS:Multi-target treatment for re-fractory class Ⅳ+Ⅴ lupus nephritis achieved efficacy:the patient got higher plasma albumin and lower 24 h urine protein quantity af-ter 14 days;the patient suffered from secondary pulmonary infection and high blood pressure;physicians adopted the pharmacist’s suggestion so that pulmonary infection and blood pressure had been controlled. CONCLUSIONS:To ensure the effectiveness and safe-ty of the multi-target treatment,clinical pharmacists should formulate individualized treatment,focus on the possible ADR and provide phamaceutical care in the field of blood pressure monitoring,infection control,etc. when participating in multi-target treatment.

This paper mainly discusses the development of animation courseware for medical statistics from the following aspects:courseware design,some related technologies in courseware making and the evaluation of courseware. The animation courseware for medical statistics can enhance self-regulated learning ability of students,from passive acceptance to initiative exploration,stimulate students'learning interest,raise their learning efficiency,and then enhance the quality of teaching.

Peptide nucleic acid (PNA) is a DNA surrogate in which the phosphate deoxyribose backbone of DNA is replaced by repeating N-(2-aminoethyl)glycine units. PNA can hybridize to the complementary DNA and RNA with higher affinity than their oligonucleotide counterparts. This character of PNA not only makes it a new tool for the studies of molecular biology but also the potential candidate for gene-targeting drugs. The non-ionic backbone of PNA leads to stable hybrids with the nucleic acids, but at the same time, the neutral backbone results in poor cellular uptake. To address this problem, studies on modified PNA progress rapidly in recent years. We reviewed literature reports combined with our study about the delivery methods, including backbone modified PNA and PNA-ligand conjugates, and the cellular uptake of modified PNA. In addition, we summarized the problems and future prospect of the cellular delivery of modified PNA.

【Objective】In order to establish the foundation for transgenic mouse model,the human thalassemic gene(β654) was cloned and sequenced.【Methods】The human β654 gene was amplified by PCR,and cloned into the plasmid BGT51 in which the human β gene was cut out aforehand.The recombinant plasmid was certified by enzyme-digestion,reverse dot hybridization and sequencing.【Results】A recombinant plasmid was obtained,which contained the human β654 gene in the correct recombinant direction.Sequencing showed that the cloned insert was correct.【Conclusions】The recombinant plasmid constructed is useful for establishing a transgenic mouse.

Objective To study the basic pathogenic cause,clinical characteristics,treatment methods and prognosis of sub-acute infective endocarditis (IE) ,and to improve the diagnosis and treatment against it Methods The basic cardiac disease,clinical characteristics,pathogenic bacteria,ultrasound cardiogram, therapy and prognosis of 36 cases of sub-acute IE was retrospectively analyzed. Results Compared to previous reports, the proportion of rheumatic cardiac disease was a little lower, whereas the proportion of congenital cardiac disease and not-recorded cardiac diseases were a little higher.The main clinical characteristics showed as fever, heart failure, increasing in number of neutrophile granulocyte,blood sedimentation and anemia, The positive rate of blood culture was 58. 33% with the most common pathogenic bacterium of streptococcus viridans. Endocardial vegetation has been diagnosed in 63. 89% of patients through-thoracic echo-cardiography. The short-term fatality rate was 19. 44% . Conclusions There have been significant changes in the basic pathogenic causes,clinical characteristics and pathogenic bacteria of sub-acute IE as compared to the previous reports. The fatality rate remains high even after active treatment. Early surgical operation is recommended to those suitable patients.

Complications are always likely to occur in the treatment of fractures. Once fracture-related complications occur,their management will be difficuh,resulting in a long handling process that increases physical and financial pain on the patients.Fea- turing“management of fracture-related complications”,this issue intends to draw attention from orthopaedists to the challenging task of prophylaxis and treatment of such problems in clinic.Not only non-union,malunion,heterotopic ossification,bone necrosis but also such systemic complications as deep vain thrombosis,soft tissue infection and necrosis are discussed.They involve long tubular bones,pelvic,proximal femur,tibial plateau and calcaneum.Authors introduce their experience from their clinical practice which can benefit readers a lot.It is well known that an effective prevention is the best treatment.In treatment of fractures,principles must be strictly followed and preventive measures taken throughout the whole process.Once a complication has been detected,therapy should be individualized 1o gain the best outcome.

Objective To retrospectively evaluate effects of early dynamization of interlocking intramedullary nail on union of tibial shaft fractures.Methods From January 2002 to Septemher 2004,75 patients with tibial shaft fractures were treated in our department with internal fixation using static interlocking iutramedullary nails.Early dy- namization(6 to 10 weeks postoperative)was adopted in 32 patients (the dynamic group) according to the fracture con- ditions,while the other 43 patients were treated without early dynamization (the non-dynamic group).The healing time of fractures and the rate of delayed union in both groups were documented.Results All the cases were followed up for a mean duration of 6.5 months (range,4 to 13 months).The mean healing time was 115.6 days (range,105 to 126 days) in the dynamic group and 124.5 days (range,119 to 133 days) in the non-dynamic group.The difference was statistically significant between the two groups (P＜0.05).There were two cases (6.2%) of delayed union in the dynamic group and four (9.4%) in the non-dynamic group.The difference was not significant (P＞0.05). Conclusion Early dynamization of interlocking intramedullary nail can promote union of tibial shaft fractures.
