To measure the relative affinity and type Specificity of neutralizing monoclonal antibodies against the hexon antigen of adenovirus type 7,a simple ELISA double antibody binding system has been developed.By this method,ralative affinity of nine MAbs was estimated from the antibody concentrations at approximately 50% of plateau binding and were ranked.The theoretical basis for this method was discussed. Hybridomas secreting antibodies of desired affinity can be selected at an early stage after fussion by measuring relative affinity of hybridomas supernatants.The type specificity was judged by the difference between end-point concentration against adeno- virus type 7 and type 3.And the relation between affinity and specificity of MAbs was discussed.

OBJECTIVETo assess the effectiveness and safety on post-stroke dysphagia in chronic stage treated with magnetic-ball sticking therapy at the auricular points.
METHODSNinety cases of post-apoplexy dysphagia in chronic stage were randomized into an auricular points group and an acupuncture group. In the auricular points group, the magnetic-ball sticking therapy was applied to subcortex (pizhixia, AT4), brainstem (naogan, AT(3,4i)), mouth (kou, CO1), cheek (mianjia, LO(5,6i)), tongue (she, LO2) and throat (yanhou, TG3) on one ear each time, and were changed on the other ear once every 3 days. In the acupucnture group, acupuncture was applied to Feng-chi (GB 20), Yifeng (TE 17), Shanglianquan (Extra), Jinjin (EX-HN 12), Yuye (EX-HN 13), Shuigou (GV 26) and Tongli (TH 5), etc. The needles were retained for 30 min in each treatment. The treatment was gi-yen once a day in the two groups and the treatment of 6 days made one session. There was 1 day at an interval among the sessions. Totally, 3 sessions of treatment were required. The video fluoroscopic swallowing study (VFSS) was performed for 4 kinds of food with different properties and shapes in each patient. The main indices were Rosenbek penetration-aspiration score, oral-retaining score and throat-retaining score. The efficacy, and the incidences of aspiration pneumonia and malnutrition were compared between the two groups. The nutrition indices were compared before and after treatment between the two groups, such as the skinfold thickness of triceps brachii muscle, serum albumin and peralbumin.
RESULTSIn 21 days of treatment, in the auricular points group, the 1 mL liquid loversol Rosenbek penetration-aspiration score (1.51 +/- 0.69), oral-retaining score (1.17 +/- 0.38) and throat-retaining score (1.30 +/- 0.66) were all lower than those (2.51 +/- 0.67, 1.63 +/- 0.72, 1.67 +/- 0.7) in the acupuncture group separately. The 10 mL liquid loversol Rosenbek penetration-aspiration score (2.27 +/- 0.65), oral-retaining score (1.60 +/- 0.50) and throat-retaining score (1.49 +/- 0.51) were all lower than those (4.19 +/- 0.73, 2.30 +/- 0.51, 2.41 +/- 0.50) in the acupuncture group separately. The 10 mL paste loversol Rosenbek penetration-aspiration score (1.68 +/- 0.81), oral-retaining score (1.11 +/- 0.31) and throat-retaining score (1.10 +/- 0.31) were all lower than those (3.91 +/- 0.68, 1.63 +/- 0.76, 1.60 +/- 0.76) in the acupuncture group separately. The 1/4 cake-form loversol Rosenbek penetration-aspiration score (2.60 +/- 0.65), oral-retaining score (1.40 +/- 0.50) and throat-retaining score (1.74 +/- 0.49) were all lower than those (4.14 +/- 1.10, 2.40 +/- 0.73, 2.30 +/- 0.83) in the acupuncture group separately. The incidence of aspiration pneumonia was 14.9% (7/47) in the auricular points group, which was lower than 55.0% (22/40) in the acupuncture group (P < 0.01). The incidence of malnutrition was 8. 5% (4/47) in the auricular points group, which was lower than 50.0% (20/40) in the acupuncture group (P < 0.01). In 21 days of treatment, the results of the skinfold thickness of triceps brachii muscle and serum albumin in the auricular points group were better than those in the acupuncture group (both P < 0.05).
CONCLUSIONThe magnetic-ball sticking therapy at auricular points achieves the definite efficacy on post-stoke dysphagia in chronic stage and decreases the incidences of aspiration pneumonia and malnutrition. The efficacy of this therapy is better than acupuncture.

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

OBJECTIVETo summarize the complications and the early clinical effect of less invasive stabilization system and the femoral condylar support plates in the treatment of AO type C distal femoral fractures.
METHODSFrom September 2007 to February 2012, 46 patients with AO type C distal femoral fractures were retrospectively studied. Of all patients 25 were treated with less invasive stabilization system including 14 males and 11 females with a mean age of (56.3±4.2) years old; according to AO classification, there were 14 cases of C1, 8 cases of C2 and 3 cases of C3 with a mean hospital stay of (15.6±1.7) days. While 21 cases were treated with femoral condylar support plates fixation including 12 males and 9 females with a mean age of (53.8±5.1) years old;there were 13 cases of C1, 6 cases of C2 and 2 cases of C3 with a mean hospital stay of (17.8±2.2) days. Comparative analysis was performed from the operation related index,postoperative complications and Evanich score of the knee joint function between the two groups at follow-up.
RESULTSAll 46 patients were followed up from 13 to 38 months with a mean time of 19.6 months after surgery. Complications included 1 case with infection,3 cases with internal fixation failure, 1 case with nonunion and 1 case with activity limitation of the affected knee. The differences in the incision length, blood loss, fracture healing time were significant between two groups (P<0.05), while there was no significant difference in the duration of operations, hospital stays and the incidence of postoperative complications between two groups (P>0.05). The statistical significance was also found in the Evanich score at last follow-up between two groups (P<0.05).
CONCLUSIONPatients with less invasive stabilization system fixation had the characteristics of less trauma, shorter fracture healing time and better functional recovery. Less invasive stabilization system had became one of the ideal internal fixations in the treatment of AO type C distal femoral fractures.

A system analysis about the microbial flora of normal and abnormal soybean sauce liquor from the high-salt-level watery state fermentation was made and the dominant bacteria and yeasts were identified.On the other hand,a discussion of effect of temperature on microbial flora was made.The results indicated that there were no obvious differences about the count of aerobe,spore-producing bacteria,enterobacteriaceae,lactic acid bacteria and anaerobe between the normal and abnormal soybean sauce liquor and there were marked differences about the count of yeasts and salt-tolerant bacteria.The predominant yeasts in normal soybean sauce were Torulopsis and Saccharomyces,accounting for 55.9% and 35.3% of the total yeasts separately,and in abnormal soybean sauce were Pichia,candida and Saccharomyces,accounting for 62.8%,17.9% and 9.0% respectively.
