Objective To compare the healing effect of compound tibial and fibular fractures with two different fixation methods of external fixators (EF) and interlocking intramedullary nail ( INF). Methods Eighty-six cases of compound tibial and fibular fractures received different treatment, 36 cases in EF group and 50 cases in INF group. The difference between two groups was statistically analyzed according to WU Yue-song and XU Bo-cheng standard and Johner-Wruh score. Results All cases were followedup for 6-24 months,average (16.0 ± 2.4) months. The excellent and good rate were 80.6% (29/36) in EF group and 88.0%(44/50) in INF group respectively. There was no significant difference between two groups (Z =-1.103,P ＞0.05). Conclusions To the compound tibial and fibular fractures patients,INF can be considered as an effective method. It's an important therapy choice with EF to heal the compound tibial and fibular fractures.

AIM:To compare the short-term and long-term curative effect between two implantation methods for treating refractory glaucoma.METHODS:A total of 150 patients with refractory glaucoma (150 eyes) were divided into Group A (treated by implantation with Ex-press glaucoma drainage device) and Group B (treated by implantation with Ahmed glaucoma valve) according to different implantation methods.Changes of intraocular pressure and anti-glaucoma drugs at different time points, the success rate of surgery, improvement of visual acuity and complications were compared between the two groups.RESULTS:The intraocular pressure of two groups at 1d, 1wk, 3, 6 and 12mo after surgery was significantly lower than that before surgery (P<0.05).The intraocular pressure of Group A at 3, 6 and 12mo after surgery was significantly lower than that of Group B, while anti-glaucoma drugs at 6 and 12mo after surgery were significantly fewer than those in Group B at the same time point (P<0.05).There were no significant differences between the two groups in 12-month success rate of operation, improvement rate of visual acuity and incidence of postoperative complications (P>0.05).CONCLUSION:The effects of implantation with Ex-press glaucoma drainage device are similar to those of implantation with Ahmed glaucoma valve in the treatment of refractory glaucoma.However, the intraocular pressure control effect of the former is better than the latter, and used anti-glaucoma drugs are fewer.

OBJECTIVETo investigate the long-term clinical effects of modified double Endobutton technique for the treatment of acromioclavicular joint dislocations of Tossy type III.

METHODSA retrospective study was done in 42 patients with acromioclavicular joint dislocations of Tossy type III treated with modified double Endobutton technique from December 2008 to December 2010. There were 24 males and 18 females, ranging in age from 21 to 56 years old (averaged, 32.5 years old). All the patients were treated with open reduction, coracoclavicular ligament reconstruction using double Endobutton technique, and repair of acromioclavicular ligament. The Karlsson system was used to evaluate therapeutic effects. The distance from coracoid to clavicle was measured to evaluate reduction loss.

RESULTSAll the patients were followed up, and the duration ranged from 2.0 to 3.2 years (averaged,2.4 years). According to Karlsson system, 32 patients got an A degree and 10 patients got a B degree at three months post-operatively; 26 patients got an A degree and 16 patients got a B degree at the latest follow-up; 6 patients got an A degree at 3 months after operation lowered to B degree at the latest follow-up. The coracoid-clavicle distance increased from (26.91 +/- 0.91) mm at 3 months after operation to (27.41 +/- 1.10) mm at the latest follow-up. Te patients treated with over-reduction during operation or with heavy physical labour work after operation had obvious widened coracoid-clavicle distance. Bone absorption was found around the plate in most cases, mainly in the clavicular side.

CONCLUSIONTreatment for acromioclavicular joint dislocations of Tossy type III with modified double Endobutton technique has satisfactory early clinical results. But with time passing, loss of reduction and bone absorption around the plate could be observed, and clinical outcomes of some cases downgrade during the long-term follow-up.

Methods IL-10 were detected randomly by ELISA technique in 127 renal allgraft recipients during the follow-up,and 20 healthy volunteers were enrolled as controls.Results Level of serum IL-10 in stable renal function group was significantly higher than that in rejection group,CAN group and control group(P

OBJECTIVETo explore the treatment of chronic calcaneal osteomyelitis with bone defect after debridement and evaluate its clinical outcomes.

METHODSFrom June 2009 to June 2011, 52 patients with chronic calcaneal osteomyelitis were treated with stage-one compound grafting of antibiotic-impregnated calcium sulfate and autogenous cancellous bone,including 12 females and 40 males with an average age of 43 years old ranging from 18 to 67. According to Cierny-Mader classification, there were 34 cases with stage III and 18 with stage IV. There were 32 cases on right side and 20 on left,with a course of 6 months to 3 years. The area of soft tissue wound ranged from 3.0 cm x l.5 cm to 23.0 cm x l2.0 cm. The clinical effects were evaluated according to infection controlling, calcium sulfate absorption,bone defect repair and heel functional recovery.

RESULTSAll patients were followed up for 2 to 3.8 years (averaged 2.8 years). Primary healing was achieved in 52 patients. Two cases of recurrence were found post-operatively, 1 case in 3 months and another in 5 months,which were cured after a second operation. Bone repair healing was gained in 1.5 to 3.5 months (averaged 2.5 months). Complete radiological absorption of calcium sulfate was found in 1.2 to 3 months(averaged 2.2 months). Local exudation after removal of drainage tube had been persisting in 10 patients for 2 to 3 months, which was consistent with the time when cacium sulfate were totally absorbed. Flap had partial necrosis in 4 cases,and the wounds were closed after appropriate treatment finally. The mean Maryland score was 88.15±7.70. There were excellent results in 32 cases, good in 14, fair in 6.

CONCLUSIONA satisfactory short-term clinical results can be gained by one-stage compound grafting of antibiotic-impregnated calcium sulfate and autogenous cancellous bone in chronic calcaneal osteomyelitis, but the long-term results need further follow-up. And much more study is also demanded to reduce the exudation of calcium sulfate.

OBJECTIVETo observe the correlation between constitution of yin deficiency syndrome (YDS) and polymorphism of HLA-DQA1/treatment response of Peg-lFNalpha therapy in HBeAg positive chronic hepatitis B (CHB) patients, and to explore constitution of Chinese medicine (CM) in response of interferon therapy.

METHODSTotally 120 HBeAg positive CHB patients who were treated with Peg-IFNalpha were enrolled, and assigned to YDS group (59 cases) and non-YDS group (61 cases) according to classification of CM constitutions. All patients were subcutaneously injected with Peg-IFNalpha-2b (1.0 microg/kg body weight) or Peg-IFNalpha-2a (180 microg), once per week. Effective efficacy was primarily judged when complete response (CR) or partial response (PR) was obtained at month 6. Those with CR or PR completed 1 year therapeutic course. HLA-DQA1 gene types were detected by polymerase chain reaction sequence specific primers (PCR-SSP). The distribution difference of CM constitutions in patients with CR or PR and their inter-group HLA-DQA1 allele frequency were compared.

RESULTSDifferent treatment responses of Peg-IFNalpha were observed in CHB patients of two different CM constitutions. The ratio of CR + PR was 61.0% (36/59) in YDS group, obviously lower than that in NYDS group [78.7% (48/61), P < 0. 05]. Patients with CR had a lower allele frequency of HLA-DQA1 * 0501 than those with no-response [14.8% (8/54) vs. 30.6% (22/72)] with statistical difference (P < 0.05). Patients with CR had a higher allele frequency of HLA-DQA1 * 0601 than those with no-response [18.5% (10/54) vs. 5.6% (4/72)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0301 was lower in YDS group than in non-YDS group [2. 5% (3/118) vs. 9.8% (12/122)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0501 was higher in YDS group than in non-YDS group [33.9% (40/118) vs. 18.9% (23/122)] with statistical difference (P < 0.05). Yet statistical significance was lost after adjustment (Pc > 0.05 for both).

CONCLUSIONSBoth constitutions of CM and HLA-DQA1 gene polymorphism af- fect HBeAg positive CHB patients' response to Peg-INFalpha. Constitutions of YDS and HLA-DQA1 * 0501 was not favorable to response, their association needed to be further studied.

Objective To study the relationship between erythromyein sensitivity and ermB gene in 143 Ureaplasma urealyticum (Uu) clinical isolates. Methods We detected the minimum inhabit concen-trations (MICs) of Uu to erythromycin by broth dilution method and MIC≥8 μg/ml was used as standard concentration of resistance to erythromycin. Polymerase chain reaction was used to detect the ermB gene and biotype Uu with primers based on multi-band antigen gene. Results The MICs, MIC50 MIC90 of Uu to erythromycin were ≤0. 125 μg/ml to ≥128 μg/ml, 16 μg/ml, and ≥128 μg/ml, respectively, with a high resistance rate of 64.38%. ermB gene, which was mainly detected in Uu with MIC≥8 μg/ml, was positively detected in 40 out of 143 Uu strains (27.97%). No significant differences of the resistance to erythromycin and positive rate of ermB gene were found between the two biovars in the study . Conclusion ermB gene may probably be one of the important genes conferring resistance to erythromycin in Uu. Further studies are needed to discover the difference of resistance and mechanism of erythromycin between the two bi-ovars.

The tissue-specific and MeJA-induced transcriptional levels of BcUGT3 and BcUGT6 in Bupleurum chinense were analyzed in the present study. The transcriptional levels of BcUGT3 in root, leaf, flower and fruit were similar and they all were higher than those in stem. The transcriptional level of BcUGT6 was the highest in leaf and the lowest in flower among in all tested tissues. With non-treated adventitious roots as control, BcUGT6's transcriptional levels were elevated to nearly 2 folds for 2 h, 8 h, 24 h, 2 d and 4 d in MeJA-treated adventitious roots of B. chinense. It showed that the transcriptional level of BcUGT6 was slightly affected by MeJA. While, BcUGT3's transcriptional levels were gradually elevated, and till 4 d after MeJA treatment, the expression level was about 7 folds than that of non-treated control. Using pET-28a (+), the expressions of two genes was investigated. Induced by IPTG, the target proteins were expressed in E. coli and then purified. All the results obtained in the present study will be helpful for follow-up bio-function analysis of BcUGT3 and BcUGT6.
