OBJECTIVETo investigate surgical outcomes of strip nail internal fixation with bone graft in treating tibial plateau fracture.

METHODSFrom May 2012 to May 2014,36 patients with tibial plateau fracture were retrospectively analyzed, including 25 males and 11 females with an average age of 43.5 (ranged from 17 to 65) years old. The time from injury to operation ranged from 3 to 10 days with an average of 5.8 days. All patients were treated with L-shaped and T-shaped strip nail internal fixation with bone graft. It was evaluated by the Knee Functional therapy assessment method of the Special Surgical Hospital of American at final following-up. Varus angle, caster angle and femorotibial angle were recorded and compared at 3 days and 1 year.

RESULTSOperative time was (2.2 ± 0.6) h on average, blood loss was (310.5 ± 36.2) ml on average, hospital stay was (14.8 ± 2.7) days on average. Thirty-six patients were followed up from 12 to 30 months with an average of 18.2 months. Fracture healing time ranged from 4 to 8 months with an average of 6.2 months. The difference is not significant among varus angle, caster angle and femorotibial angle at 3 days and 1 year. According to the knee functional therapy assessment method of the Specialized Surgical Hospital of American, 18 cases got excellent results, 13 good, 4 moderate and 1 poor.

CONCLUSIONStrip nail internal fixation with bone graft for the treatment of tibial plateau fracture could effectively prevent the joint surface from secondary collapse, and achieve anatomic reduction, stable fixation and earlier functional exercise in further to get satisfied clinical effects.

BACKGROUNDThe cochlear hydrops analysis masking procedure (CHAMP) is a new diagnostic technique for Meniere's disease (MD). But its value has not been well proven. This study aimed to evaluate the diagnostic value of CHAMP for MD.

METHODSCHAMP test was taken in three populations using the Auditory Evoked Potential system delivered by Bio-logic Systems Corporation: (1) otologically normal subjects; (2) patients clinically diagnosed with definite MD; (3) patients clinically diagnosed with probable and possible MD.

RESULTSAccording to the comparison between the normal and definite MD group, if the abnormal criterion of CHAMP was defined as latency delay less than 0.3 ms, then the corresponding sensitivity was only 52%. However, if the abnormal criterion was defined as latency delay between 0.6 and 3.8 ms, then a sensitivity of 93% and a specificity of 100% can be achieved. The complex amplitude ratio showed a significant overlap between normal and definite MD group. If the abnormal criterion was defined as a complex amplitude ratio less than 0.95, the corresponding specificity was only 50%. However, if the abnormal criterion was defined as less than 0.80, the corresponding sensitivity was 60%, and the specificity was 97%. If the abnormal criterion of CHAMP was defined as latency delay less than 0.6 ms or the complex amplitude ratio less than 0.80, CHAMP result can be obtained in all subjects with good sensitivity and specificity.

CONCLUSIONSCHAMP can differentiate patients with Meniere's disease from otologically normal subjects with high sensitivity and specificity. The recommended criterion of abnormal CHAMP was a latency delay less than 0.6 ms or a complex amplitude ratio less than 0.80.

To clone mouse phage antibodies against H-Y antigen from a phage antibody library, three cycles of affinity enrichment of the mouse phage antibody library with male spleen cells and two cycles of nonspecific absorption with female spleen cells were performed. The presence of mouse Fab on the phage surface was determined by ELISA and sequence analysis. 9 of 15 strains can bind to male spleen cells with the specific activity. Recombination rate of the phage antibody library clones is 60%. Sequence analysis of the PCR products of plasmid DNA of E5 clones show VH and Vkappa had common characteristics shared by other known variable region of antibodies. The mouse phage Fab antibody could be used for identifying H-Y antigen, and for the development of sex determination of early embryos in mammals.

Objective To learn the current situation of knowledge,attitude and practice (KAP)about tuberculosis prevention and treatment among close contacts of tuberculosis patients in Yangzhou City and to explore the influencing factors and relationship of KAP.Methods A total of 460 TB(tuberculosis)patients'families in Yangzhou were randomly selected by means of cluster random sampling.And 746 close contacts of tuberculosis patients were investigated by face - to - face interview.Their basic information,knowledge ,belief and behavior of TB were analyzed by descriptive analysis and multivariable logistic regression analysis.Results The overall awareness rate of tuberculosis prevention and control was 58.30% ,and the rate of positive belief was 50.19%,and the behavior holding rate was 59.25%.The multivariable logistic regression analysis showed that diagnostic types,degree of education and location were the major influencing factors. Conclusion Close contacts with low education level and with smear positive patients in the family should be paid more attention.

OBJECTIVEIntroducing a comprehensive technique to reconstruct burn scar contracture or deformities using integra (artificial dermis) with large epidermal skin grafting or ulth-thin split-skin.

METHODSThe wounds following contracture scar or deformities excised or loose were covered with the integra which was flattened and fixed perfectly, after a 2 approximately 4-week period, the out layer was removed then covered with large sheets of epidermal grafts, which was of thickness from 0.0028 inc to 0.0048inc (0.07 approximately 0.12 mm), or ulth-thin split-skin of about 0.006inc (0.15 mm) thickness, harvested using the electric or air power dermatome, the edge of the graft sheet attached together with the borders of wound using nanoparticles-Ag-gauze stripe adding sutures of the 5-0 threads or the skin stapler, dressed with vaseline gauzes in the inner layer and the nano-particles Ag gauze on the outer surfaces.

RESULTSNineteen sites of 15 cases including 5 sites in trunk and 14 sites in extremities from 1999.8 to 2003.6 were treated using this technique in this study, the wound areas following scar excised was about 10 cm x 25 cm approximately 30 cm x 75 cm, of them 12 cases covered with a large sheet of ultr-thin split-skin (in early time) and 7 cases with a large sheet of epidermal grafting and all of them was survival. The colour and texture of the reconstruction sites were very good and can be compared favorably with normal skin after a half year-four year following up period, because all donor sites healing without scarring, the appearance in the epidermal graft donor is better than that in split-thickness skin donor.

CONCLUSIONSIntegra with large sheets of epidermal grafts applied for scar contracture disformities is an effective and useful method, especially the epidermal grafts offered a satisfying result in the donor healing.

OBJECTIVETo investigate the relationship between hepatitis C virus (HCV) genotype, serum viral load and ALT levels, and the factors associated with the viral relapse after IFN treatment in patients with chronic hepatitis C.

METHODSThe HCV RNA levels were determined with Cobas Amplicor Monitor Test, version 2.0, and HCV genotypes were examined by means of PCR products of 5' NTR digested with restriction endonucleases. The patients with chronic hepatitis C were treated with PEG-IFN alpha -2a and Roferon-A for 24 weeks. Those with a viral response after 24 week treatment were followed for an additional 24 weeks. The association of clinical characteristics, such as sex, age, the way of the HCV infection, IFN treatment history and platelet counts, and the HCV genotype, virus load and medicine used for the viral relapse after IFN treatment were analyzed.

RESULTSOf the 208 chronic hepatitis C patients, the ALT levels were not related to HCV RNA levels (r = 0.093, P > 0.05). No difference of ALT levels between HCV genotypes was found, and the HCV RNA load was also of no difference between HCV genotype 1 patients and non 1 patients. Of the 119 patients with viral response after 24 week treatment, 58 cases (48.7%) relapsed after another 24 week's follow-up. Relapse was not significantly related to the clinical characteristics, such as sex, age, mode of the infection, treatment history of IFN, AST/ALT ratio, platelet counts and the baseline viral load. Among patients with genotype 1 virus, the relapse rate was significantly higher than those patients with non-genotype 1 virus (54.5% vs 32.1%, P=0.039). The relapse rate after PEG-IFN alpha -2a treatment was lower than that of Roferon-A treatment (47.0% vs. 52.8%), but not significantly.

CONCLUSIONThe viral relapse of chronic hepatitis C patients after IFN treatment was significantly associated with the genotypes of the HCV.

OBJECTIVETo evaluate the efficacy and investigate the influencing factors of the interferon (IFN) retreatment for patients with chronic hepatitis C relapsed after a previous IFN treatment.

METHODSA retrospective study was designed to analyze the retreatment with IFN of 60 relapsed chronic hepatitis C patients. All patients were from a randomized, opened and multi-center clinical trial about the efficacy and security of PEG-IFNalpha-2a compared to CIFNalpha-2a in the treatment of chronic hepatitis C in China. There were 35 patients treated with PEG-IFNalpha-2a and 25 with CIFNalpha-2a. The main parameter to evaluate the efficacy was sustained viral response (SVR) rate. The influence of viral concentration in serum, genotype and drug categories on the responses to IFN were analyzed.

RESULTSFor all the patients, the end of treatment virus response (ETVR) and SVR rates were 55.00% and 35.00% respectively. ETVR rate of PEG-IFNalpha-2a was significantly higher than that of CIFNalpha-2a (74.29% and 28.00% respectively, P < 0.01). SVR rate of PEG-IFNalpha-2a was also markedly higher than that of CIFNalpha-2a (45.71% and 20.00% respectively, P < 0.05). However, there was no significant difference between the high and low viral load groups. Among the patients with genotype 1, ETVR and SVR rates of PEG-IFNalpha-2a (75.00%, 45.83%) were significantly higher than those of CIFNalpha-2a (22.22%, 11.11%), (P < 0.01, P < 0.05 respectively), but in patients with genotype non-1, there were no such differences between the two groups.

CONCLUSIONSome relapsed patients were not responsive to the IFN retreatment. The efficacy of PEG-IFNalpha-2a was superior to CIFNalpha-2a. The conventional IFN was not suggested to be used in the relapsed cases with genotype 1. The viral load was not associated with the efficacy of IFN retreatment.
