Objective To establish a method of TRFIA with high sensitivity and broad detecting range for serum HBV large surface protein (HBV-LP).Methods The monoclonal antibody of HBV-LP was covered on the microwell plate and incubated with HBV-LP in blood sample,then Eu3+ labeled antibody of HBs was added.HBV-LP in standard substance,blood samples of 66 chronic hepatitis B patients and 30 healthy controls was detected by the TRFIA and ELISA.x2 test and linear correlation analysis were used for data analysis.Results The dose-response curve of standard substance with TRFIA had good linear correlation (r=0.999).Normal reference range was established at 0-1.36 mg/L based on the ELISA results of 30 healthy controls.The sensitivity was 0.10 mg/L.The specificity was 100％ (30/30).Correlation coefficient between the TRFIA and the ELISA was 0.800 9 (P＜0.001).The positive detecting rates of the 2 methods were significantly different (89.4％(59/66) vs 77.3％(51/66),x2 =6.13,P＜0.01).The recovery rate for HBV-LP was between 95.93％-107.62％.The effective detecting range(CV＜10％) of TRFIA was 1.35-2 764.00 mg/L,and that of ELISA was 10.8-691.0 mg/L.Conclusion The TRFIA was established for HBV-LP detection with higher sensitivity and wider detecting range compared to ELISA.It has potential value for HBV screening and monitoring of antiviral therapy.

ObjectiveTo evaluate the influence of laparoscopic operation on pH value, phagocytic function of neutrophil, immunoadhesion activity of RBC CR 1 (complement receptor typeⅠ) in abdominal cavity. Methods Determination of the pH value, phagocytic function of neutrophil, immunoadhesion of RBC CR 1 in abdominal exudatives during laparoscopic procedures was undertaken and results were compared with the relative indexes detected in peripheral vein blood. Results The average pH value was 7.41, the percentage of the phagocyte was 74.6%, phagocytic index 55.7, and immunoadhesion activity of RBC CR 1 was 58% in blood during laparoscopic operation. While the average pH value was 7.14, the percentage of the phagocyte 65.6%, phagocytic index 47.6,and immunoadhesion activity of RBC CR 1 50% in the abdominal exudatives. Conclusion Compared with the peripheral vein blood indexes, the intraabdominal pH value, phagocytic function of neutrophil and immunoadhesion activity of RBC CR 1 decreased significantly during laparoscopic operation. The intraabdominal inflammation may diffuse with the effect of CO 2 pneumoperitoneum when patients with serious inflammation receive laparoscopic operation.

Objective To analyze the distribution of tophus in ankle and tarsal joints by multislice spiral computed tomography (MSCT)and to explore the pathogenesis of gout.Methods 34 patients with a documented diagnosis of gout underwent CT examina-tion of bilateral ankle and tarsal joints,and 55 ankle and tarsal joints were observed tophus.The sites of tophus deposition were cate-gorized into groups of ligament,tendon and joint in order to record and analyze.Results The tophus were showed at the anterior talofibular ligament (n=38),the medial ligament (the site of talus and calcaneus)(n=30)and the interosseous talocalcaneal liga-ment (n=29)(P <0.05)in the group of ligament;at achilles tendon (n= 18),followed by tibialis posterior tendon (n= 7)(P <0.05)in the group of tendon;at articulations intercuneiformes (n=1 5)and inferior tibiofibular articulation (n= 10)(P <0.05 )in the group of joint.Conclusion In ankle and tarsal joints,tophus is commonly deposited at the anterior talofibular ligament,at the achilles tendon and the articulationes intercuneiformes.

Objective To make a comparison between the plain radiograph, CT, and MR findings of gouty arthritis and to analyse the relationship between clinical data and imaging findings. Methods Fifty-four joints of 33 patients with a confirmed diagnosis of gouty arthritis were included in this study. In the morning, the blood uric acid level of patients was tested before meal. In the afternoon, their clinical data were recorded and joints were examinated by plain radiography, CT, and MRI. The imaging findings were evaluated by tophi, bone erosion, soft tissue swelling, hydrarthrosis, synovial thickness, and bone oedema. The data was analyzed by Chi-square test, indepentdent-samples t test, and logistic regression. Results The Chi-square test was utilized to evaluate number of joints with tophi(CT>plain radiography, MR>plain radiography, P<0. 01), soft tissue swelling (MR>CT>plain radiography, P<0. 01), hydrarthrosis(MR>CT, P<0. 01). In addition, 35 joints had bone oedema and 50 joints had synovial thickness. The course of disease(tophi positive group vs tophi negative group, P<0. 01) was analyzed by indepentdent-samples t test. The tophi's causative agents including bone erosion and course of disease were analysed by logistic regression(P<0. 01). Conclusions MRI is superior to CT and plain radiography on the early diagnosis of gout. Tophi and bone erosion may not affect the blood uric acid level. With the progression of disease, the probability of tophi formation increases. The relationship between the formation of tophi and bone erosion may be interpromotied.

Objective To explore the influence of network intervention on lifestyle and behaviors habit of the middle -aged patients with hypertension.Methods All 300 middle -aged patients with hypertension were randomly assigned into the study group and the control group.Each group had 150 cases.All patients in the both two groups were given hypotensive drugs according to treatment specification of hypertension.The patients in the study group received a network intervention for 2 years,while the patients in the control group received an outpatient service follow-up.The difference of lifestyle and behaviors habit of the patients in the two groups were observed and compared. Results There were no significant differences with all items of the lifestyle and behaviors habit of the patients between the two groups before intervention(P >0.05 ).In the 12th end of month after intervention,there were no significant differences between the two groups with the items of smoking control,working and resting regularly,hobby and psychological balance(P >0.05),but other items in the study group were significantly better than those in the control group(Z =-3.062,-2.509,-2.239,-2.056,-2.126,-2.045,-2.023,all P <0.05).In the 24th end of month after intervention,all items in the study group were significantly better than those in the control group (Z =-4.078,-3.792,-2.080,-2.098,-1.985,-2.478,-2.173,-2.478,-3.290,-2.514,-2.730,all P <0.05 ).Conclusion The network intervention can significantly improve lifestyle and behaviors habit of the middle -aged patients with hypertension.Its effect is much better than that of outpatient service follow -up.

Objective To explore the feasibility and efficiency of the treatment of lumbar degenerative diseases after transforaminal lumbar interbody fusion(TLIF)and posterolateral fusion(PLF)procedures in which unilateral pedicle screw fixation was used.Methods From December 2006 to August 2008,78 cases with the lumbar degenerative diseases who received lumbar posterolateral fusion were analyzed.There were 48 cases of which underwent TLIF and PLF procedures with unilateral pedicle screw fixation(unilateral group),including 25 males and 23 females with an average of 47.6 years;and 30 cases of which underwent TLIF and PLF procedures with bilateral pedicle screw fixation(bilateral group),including 21 males and 9 females with an average of 50.5 years.The clinical effects between the two groups were evaluated with Oswestry disability index and visual analogue score(VAS)index.The operation time,blood loss,fusion rates and intervertebral collapse rates were also compared.Results Oswestry disability index,low back pain VAS index and skelalgia VAS index in both groups showed statistical significance between preoperation and 3 months,or 3 months and 1 year postoperatively.There was no difference in score improvement between the two groups.There were difference in operation time,blood loss and cost of hospitalization between unilateral and bilateral group.The former was lower.There was no difference in postoperative length of stay between the two groups.The fusion rate of unilateral group and bilateral group were 91.7%(44/48)and 93.3%(28/30),respectively.Conclusion Auto graft combined with unilateral pedicle screw fixation provids better spinal instant stability.TLIF and PLF with unilateral pedicle screw fixation was a satisfactory method in treating degenerative disease of lumbar vertebrae.

Objective To compare the effect of microsurgery and conventional surgery in the repair of tendon rupture and the effect of postoperative adhesion prevention. Methods From February 2011 to December 2016,seventy?two patients with finger tendon rupture treated in Dongfeng Hospital Affiliated to Hubei Medical College were selected as the research objectand then randomly divided into the observation group and the control group,36 cases in each group. The observation group was treated with microsurgery treatment,the control group was treated with the traditional surgical treatment to record postoperative prognosis and adhesion of the two groups. Results At 12 weeks after operation,the recovery rate of tendon in the observation group and the control group were 94. 4％ (34/36)and 75％(27/36),respectively,the data in the observation group was significantly higher than that in the control group (χ2=5. 552, P<0. 05 ) . At the same time, Carroll score of upper limb function in the observation group at 4 weeks and 12 weeks after the surgery were (85. 55±8. 29) and (102. 49 ±10.82),significantly higher than those in the control group ( (74.25±8.53)％,(91.44±12.49) ),the differences were statistically significant (t=6. 948,5. 323,P<0. 05). At 12 weeks after operation,the adhesion rate of tendon in the observation group was 2. 8％ ( 1/36 ) , significantly lower than that of the control group ( 16. 7％ ( 6/36) ) , ( P<0. 05 ) . Conclusion Compares with the conventional surgery, microsurgery in the treatment of tendon rupture repair can promote the repair of tendon tissue,improve the upper limb function,and reduce the occurrence of postoperative tendon adhesion.

Objective To observe the gastric changes in adult male Sprague-Dawly (SD) rats irradiated by the single large dose electron beam,providing animal experimental evidence for intraoperative radiotherapy for gastric cancer.Methods Thirty-eight SD rats were randomly divided into the control and experimental groups.The stomach of the rats in the experimental group were subject to single 6 MeV 20 Gy irridiation by using the patent technology of Accurate Irradiation Experiment Table for Small Animal Radiation.The general conditions,gastric injury and body weight change were observed at different days following irradiation.Results The most severe gastric damage of rats was observed on the 14th d after irradiation.The gastric injury was gradually repaired accompanied with glandular atrophy at 28 d postirradiation,and the gastric injury was manifested as cellulose fibrinous repair on the 56th d after irradiation.Within 1 week post-irradiation,weight loss was noted in the experimental group,which significantly differed from the rats in the control group (P＜0.05).During the 2nd week,the body weight was increased in the experimental group,significantly lower compared with the rats in the control group (P＜ 0.05).The body weight of rats did not significantly differ between two groups at 6 weeks after irradiation (P＞ 0.05).Conclusions The most severe gastric injury is observed at 2 weeks after the single-dose 6 MeV electron beam 20 Gy irradiation,whereas no gastric perforation occurs.The gastric injury can be restored to normal status within 8 weeks following irradiation.

Objective To establish a fast and quantitative light initiated chemiluminescent assay (LICA) method for high mobility group box1 (HMGB1) determination.Methods Two strains of paired HMGB 1 monoclonal antibodies were used.One was used to coat receptor microspheres.The other was labeled with biotin first and then composed with chain mildew element of affinity donor microsphere to form LICA method for HMGB1.After optimizing the reaction system,the technical specifications of the method was evaluated.Serum HMGB1 levels of common pneumonia patients (CPP) and severe pneumonia patients (SPP) were measured and compared with that of health controls.Two-sample t test was used.Results The sensitivity of LICA was 0.1 μg/L,with linear measurement ranging from 0.1 to 1 000 μg/L.The precisions of intra-and inter-analysis were 1.74％-2.92％ and 1.93％-3.73％ respectively,both were lower than 5％.The recovery rate was 99.74％ (range:94.53％-106.37％).The correlation coefficient of LICA and enzyme-linked immunosorbent assay (ELISA) was 0.888 2.The LICA method had good specificity and no obvious cross reaction with HMGB2 and HMGB3.The serum HMGB1 level in CPP (n=35) and SPP (n=25) was significantly higher than that in health controls (n=35):(6.76±3.13),(19.69±+9.04) vs (1.49±+0.74) μg/L;t values:-5.447 and-5.186,both P＜0.01.The HMGB1 levels between CPP and SPP were also significantly different (t=-3.500,P＜0.01).Conclusions The established LICA method of HMGB1 has high sensitivity and specificity with reliable results.This method is also homogeneous,fast and cleaning-free,thus has a good prospect in clinical application.
