The lumber ligaments play an important role in spinal bsomechanics. The results of three-dimensional finite element analysis showed that one of functions of lumbar ligaments is transmission of the tensile load between the lumbar vertebrae. The anterior longitudinal ligament is loaded in extension of lumbar spine and the resistance to the tensile load in flexion is provided by other ligaments. These ligaments are subject to much more tension with degsneration of the intervertebral disc so that a series of pathological changes occur. Relevant significance in clinical aspect is also discussed.

Objective To investigate the feasibility and effectiveness of internal jugular vein (IJV) intervention therapy in patients with cerebral venous sinus thrombosis (CVST)with color Doppler ultrasound (CDU). Methods Twelve patients with CVST diagnosed by CDU and the 13 IJV lesions (localized luminal stenosis in 9 cases,venous long-segment slender in 2 cases,and right IJV localized luminal stenosis,and long-segment slender on the left in 1 case)confirmed by magnetic resonance venography (MRV)and/ or digital subtraction angiography (DSA)were enrolled retrospectively. CDU examinations were used at 1 week before and after IJV intervention therapy,6 months,1 year,and 2 years. The changes of the maximum diameter and the maximum velocity (V max )of the IJV were compared. The success rate and the long-term efficacy of the intervention therapy were analyzed. Results One week after treatment,the CDU examinations showed that the diameter of IJV stenosis in 13 IJV were increased significantly compared with those before procedure (4. 7 ± 2. 1 mm vs. 2. 3 ± 1. 3 mm;t = 5. 325,P < 0. 01). The velocity of blood flow of IJV was improved compared with before procedure (localized stenosis in 10 IJV[50 ± 15 cm/ s vs. 87 ± 24 cm/ s];t = 6. 285,P < 0. 01). Six of the 12 patients were followed up for a mean of 18 ± 7 months, two patients had restenosis after balloon dilatation. Conclusions For CVST patients with IJV lesions,the preliminary observation has indicated that IJV intervention therapy may improve the lesion lumen and hemodynamics. However,the intervention therapy,especially after balloon dilatation,the incidence of restenosis is higher. CDU can be used as an objective evaluation means for the long-term efficacy of IJV stenosis.

AIM: To establish human lymphocyte cell line secreting monoclonal antibody against Rhesus(D) antigen and analyse the nucleotide and deduced amino acid sequences of a human monoclonal anti-D Fab fragment. METHODS: By using PCR method, the cDNA of human anti-(Rhesus D) antibody(lgM ?)Fab fragment was amplified from an Epstein- Barr-virus-transformed cell line. Cloning and subsequent sequence analysis of the Fab fragment was performed. The deduced amino acid sequence was compared and analysed with previously published sequences. RESULTS : A band of approximate 700 and 650 base pairs was amplified using lgM heavy chain primers and ? light chain primers, respectively. Sequence analysis indicated that the deduced amino acid sequences was in agreement with the characterization of the amino acid present in the human lg Fab fragment. CONCLUSION: The cloning and sequencing of a human anti-Rhesus (D) antibody Fab fragment cDNA will make benefits for production of recombinant anti-Rhesus (D) antibody and prevention of Rh haemolytic disease in the newborn.

Objective To design a wearable rehabilitation device suitable for home and society COPD treatment aiming at the deficiency in the COPD pulmonary rehabilitation in China. Methods Physical activity therapy and pulmonary physical therapy methods which play very important role in the COPD pulmonary rehabilitation were studied. Physiological parameters of the COPD patient were acquired non-intrusively with wearable technique. Biofeedback technology was used in the respiratory rehabilitation therapy. Target heart rate and SPO2 were used as parameters for the activity intensity assessment. Results Wearable COPD pulmonary rehabilitation device based on breathing biofeedback was fabricated. Conclusion This device is a favorable rehabilitation tool for COPD patients to do self-training at home or community.

Objective Study on producing human monoclonal antibodies against Rhesus (D) antigen that was suitable for use as blood group typing reagent. Methods B lymphocytes from a Rh negative woman, which can produce anti D antibodies were transformed by Epstein Barr virus(EBV). Antibody secreting cells were enriched by RhD + group O erythrocytes and cloned by limited dilute method. By using one step emzymatic method on microplates, one thousand normal blood donors with a common Rh phenotype were tested with the supernatant of cell culture medium as well as a polyclonal human anti D and a commercial monoclonal anti D serum. Results Three human B lymphocyte lines secreting monoclonal antibodies to Rh (D) were established. One of them produced lgM antibody. The titer of the monoclonal antibodies was 64～128. Study on 1000 blood donors, the results did not show any discrepancy among the three different anti Rh(D) serum. Conclusion These monoclonal antibodies against D antigen could be used in Rh(D) typing.

Objective To quantify the validity and reliability of the Hong Kong version of the functional test for the Hemiplegic Upper Extremity (FTHUE-HK).Methods Forty-two stroke patients were studied.Patients were assessed twice within one week using the FTHUE-HK,the upper extremity component of Fugl-Meyer movement assessment (FMA) and the modified Barthel index (MBI).The test-retest reliability and inter-rater reliability of the FTHUE-HK were thus quantified.The FTHUE-HK's validity was evaluated according to the correlation between the FTHUE-HK,FMA and MBI results.Results Significant correlations between the three assessments were demonstrated(P≤0.01).The intra-and inter-class correlation coefficients were 0.983 and 0.985 respectively.Conclusion The FTHUE-HK is a simple and useful assessment of the upper extremity function of stroke patients with good validity and reliability.
