OBJECTIVETo explore the clinical effects of minor bone anchors and palmaris longus tendon graft in treating chronic mallet fingers deformity.

METHODSFrom January 2008 to June 2013, 26 patients with chronic mallet fingers deformity were treated with minor bone anchors and palmaris longus tendon graft. There were 18 males and 8 females, aged from 18 to 52 years old with an average of (32.0±1.3) years. Among them, 8 cases caused by machine injury, 6 cases by fall injury, 6 cases by sprain from fight, 4 cases by tendon spontaneous rupture, 2 cases by knife trauma. There was no tendon attachment of extensor tendon check in 16 cases, and with 0.3 to 0.5 cm tendon attachment in 10 cases. All patients had the flexion deformity and the disability of dorsiflexion activity. During operation, the distal interphalangeal joint was fixed in 10° to 20° dorsiflexion by a Kirshner wire, the minor bone anchor was used to reconstruct the extensor tendon insertion, the palmaris longus tendon slice was transplanted the decayed area of extensor tendon insertion. Four weeks postoperatively, the Kirshner wire was removed and the plaster external fixation was used, and the patient began function exercises. Postoperative complications were observed and fingers functions were assessed according to Dargan standard.

RESULTSThe patients were followed up from 6 to 14 months with an average of (5.0±0.3) months. Wound superficial infection occurred in 2 cases, the skin pressure ulcer in 2 cases, joint activities disability in 1 case; these symptoms got improvement after symptomatic treatment. Traumatic arthritis occurred in 2 cases, 1 case was improved after treatment, and 1 case had chronic pain for a long time. No internal fixation loosening or breakage and tendon rupture were found. According to Dargan standard to evaluate the finger function, 17 cases got excellent results, 8 good, and 1 poor.

CONCLUSIONIt is an effective way to treat the chronic mallet finger deformity using minor bone anchors and palmaris longus tendon graft, and the method has advantages of reliable fixation, easy operation, satisfactory effect and less complication.

Bioethics, one of the focus subjects in 21 century,attracts the attention in the worldwide.Originated from western developed countries,it has been branded with distinct western civilization,which is disadvantageous to the development of the subject.Some suggestions are put forward as following: 1.Communication between the East and the West should be promoted in order to form a solid multi-cultural base for bioethics. For instance, in America ethics bears the imprint of religious conventionality,while in China politics is infiltrated into traditional ethical ideas. Both of them are not perfect. So they cannot form the base of bioethics. 2.Research on the "base line" of the bioethics should be emphasized in order to provide freer academic atmosphere. Transplanting the western bioethical ideas to the developing countries will never work. As for the bioethical"base line",different countries should establish feasible ethical codes according to their own actual situations. 3.Scientists should be encouraged to adopt various technical ways to explore the problems in the field of bioethics.Such methods as tissue-engineering,antologous stem-cell replanting and cell diffrenttation inducing may bring about earlier breakthrough than fetus stem-cell.Equal attention,encouragement and support should be given to bioethics.

Objective To observe the characteristic features of musculoskeletal ultrasound (MSUS) in gouty arthritis (GA) and to assess its value in GA diagnosis.Methods Patients with GA and non-GA who underwent MSUS examination in Chinese PLA General Hospital were enrolled in this study. The synovitis,tenosynovitis,soft tissue swelling,bone erosion,bursitis and ossification were measured by greyscale ultrasound,and the synovial vascularity was measured by power Doppler ultrasound to evaluate the degree of inflammation.Results The ultrasound images of GA were intended to have specific features like tophus,hyperechoic deposition on the surface of the articular hyaline cartilage ( double contour sign ),hyperechoic deposition in the synovium appearing as bright stippled foci,and bright strap in tendons with a significant difference when compared with non-GA group (P ＜ 0.05).The percentage of tenosynovitis and bone erosion in non-GA group was higher than that in the GA group with a significant difference (P ＜0.05 ). Tophus,double contour sign,bright stippled foci or bright stippled foci in tendons together suggested gout with a specificity of 92.4％ and a sensitivity of 60.3％,the AUC of ROC was 0.764 ( P ＜0.05).Conclusion Tophus,double contour sign,bright foci and bright strap detected by MSUS are of diagnostic value on GA and MSUS may be a promising tool in diagnosing GA.

ObjectiveTo explore the clinical presentation, diagnosis, treatment, and outcome of the Barth syndrome (BTHS).MethodsClinical data were collected and analyzed from 3 patients with conifrmed genetic diagnosis of BTHS from June 2013 to October 2014.ResultsAll of the 3 patients were males and two of them were twins. The main clinical manifes-tations of the 3 patients were cardiomyopathy and heart failure, accompanied by different degrees of trabeculations of the left ventricle. Two of them were diagnosed of left ventricular noncompaction (LVNC). All of the 3 patients presented with motor retardation, muscle weakness, growth delay and signiifcantly increased urinary excretion of 3-methylglutaconic acid (3-MGC). One patient was found to have neutropenia. All 3 patients hadTAZ gene mutations which included a novel missense mutation (c.527A>G, p.H176R) detected in the twins and a known nonsense mutation (c.367C>T, p.R123X) identiifed in the other patient. All of the mutations were inherited from their mothers. During the follow-up, the twins died at 7 months old and 7.5 months old respectively. The other patient was still alive.ConclusionBTHS is one of the causes of cardiomyopathy in children. In the male patients who presented with muscle weakness, neutropenia, and increased urinary excretion of 3-MGC, especially in those com-bined with LVNC, BTHS should be screened.

Objective To study the application of the combined detection of Golgi glycoprotein 73(GP-73),phosphatidylinositol proteoglycan 3(GPC3 )and percentage of AFP heteroplasmon(AFP-L3%)in the diagnosis of primary hepatocellular carcinoma (PHC).Methods The concentrations of GP-73,GPC3 and AFP-L3 were detected by enzyme-linked immunosorbent assay(ELISA) in 154 patients with PHC(PHC group),78 patients with cirrhosis(cirrhosis group)and 56 healthy subjects(control group).Then the detection results were statistically analyzed.Results The levels of GP-73,GPC3 and AFP-L3% in the PHC group were signifi-cantly higher than those in the liver cirrhosis group and the control group(P <0.05).The positive rates of GP-73,GPC3 and AFP-L3% in the PHC group were 66.2%,72.1% and 53.2% respectively.The positive rate in the combined detection of these three in-dices could reach 97.9%,which was higher than the sensitivity and accuracy in any single index detection and the combination de-tection.In the PHC group,the comparison between different levels of GP-73 and AFP-L3% with the AFP levels showed the statis-tically significant difference(P <0.05 ).Conclusion The combination detection of GP-73,GPC3 and AFP-L3% can improve the sensitivity and accuracy for diagnosing PHC and has reference significance in the differential diagnosis of early PHC.
