OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy and repair of the injured posteromedial complex structure of the knee joint in the treatment of posterolateral knee dislocation with multiple ligament injuries.

METHODSFrom March 2008 to August 2012,22 patients (16 males and 6 females, ranging in age from 20 to 53 years old, with an average of 30.5 years old) with posterolateral dislocation of the knee were treated with primary reconstruction of ACL and PCL, combined with the repair of injuries in the posteromedial complex and soft-tissue. Eight patients had injuries caused by sports,5 patients road accidents and 9 patients falling down. The ACL was reconstructed using the gracilis and semitendinosus tendons. The PCL was reconstructed using LARS artificial ligaments (14 cases), or gracilis and semitendinosus tendons (8 cases). Suture repair was performed in 17 patients with posteromedial ligament injuries,and self-semitendinosus strengthening operations were performed in 5 patients. Continuouspassive montion (CPM) and active exercises were executed after operation at early stage. The IKDC and Lysholm system were used to evaluate therapeutic effects.

RESULTSAll the patients were regularly followed up, and the duration ranged from 11 to 56 months (averaged, 39 months). According to the IKDC scale,9 patients got a grade A result, 10 got a grade B result, and 3 got a grade C result. The IKDC subject score was 89.6±3.1 and the Lysholm scores was 90.7±1.8 at the latest follow-up, which were both better than those before operation.

CONCLUSIONReconstructing the ACL and PCL and repairing injured posteromedial complex of the knee followed by an active rehabilitation is an effective method to treat posterolateral knee dislocation.

Objective To analyze the cause and treatment of the postoperative complications using one-stage posterior spinal osteotomy in the treatment of severe spinal deformity.Methods From September 2006 to May 2013,17 patients with severe spinal deformity (congenital scoliosis in 11 cases,congenital kyphosis in 4 cases,and congenital kyphoscoliosis in 2 cases) underwent one-stage posterior spinal osteotomy,including 5 males and 12 females with an average age of 22.6 (14-51) years.The preoperative mean coronal Cobb angle was 109° (85°-160°) while the mean sagittal Cobb angle was 104° (65°-152°).Two patients had neurological symptoms preoperatively whose spinal cord function was D,evaluated by ASIA classification.All patients were treated with pedicle subtration osteotomy and pedicle screw internal fixation,which SPO osteotomy 2 cases,PSO osteotomy 11 cases,VCR osteotomy 4 cases.Results There were 17 cases of complications in 147 patients,the complication rate was 11.6％(17/147).The causes were as followed,screw malposition in 2 cases,compromised by close of resected areas in 2 case,residual bone compression in 1 case,acute spinal cord injury in 2 cases,infection in 2 cases,broken stick or loosen hat in 3 cases,and superior mesenteric artery syndrome in 5 cases.Postoperative neurological complications occurred in 7 cases.Two cases with preoperative ASIA D became ASIA C,5 cases with normal nerve function became ASIA C in 2 cases and ASIA D in 3 cases.After surgical exploration,given Methylprednisolone and neurotrophic drugs,removal or changing of the internal fixation,anti-infection and symptomatic treatment,15 cases recovered completely and 2 cases improved partially.Conclusion One-stage posterior spinal osteotomy for severe spinal deformity is technical demanding and risky,and the postoperative complications are common.Appropriate operative procedure,close observation of sensation and motor function,timely surgical exploration and nerve decompression,and early brace wear are all required.

Therapeutic HIV vaccine was considered as a hopeful curative method for AIDS patients. However, there is still no suitable HIV animal model for vaccine study since the difference in the immune system between human and animals. To evaluate the therapeutic effect of combined immunization strategy with multiple vector vaccines in macaque models. Plasmid DNA, recombinant Ad5 and MVA vaccines which expressing SIV gag and env genes were constructed. Sequential and repeated immune strategy were applied to immunize mice with these three vaccines. Cellular immune responses in mice immunized with these three vaccines were measured by ELISPOT test in vitro and CTL assay in vivo. The results were analyzed and compared with different antigen combination, order of vaccines and intervals to choose a suitable immunization strategy for macaque immunization in future. It indicated that strong SIV-Gag/Env-specific cellular immune responses were induced by these three vector vaccines. It laid a foundation for evaluating the therapeutic effect of combined immunization strategy with multiple vector vaccines in SIV infected macaque models.

Objective To explore the sonographic characteristics and to evaluate its diagnostic value of hepatic lymphoma (HL). Methods The clinical data and abdominal sonographic ifndings of 18 consecutive patients with histological proven diagnosis of lymphoma with liver involvement were reviewed, including contrast-enhanced ultrasound (CEUS) images. Results The liver sonographic features of 18 HL were differentiated as three types including nodular, diffuse and mixed type. Nodular type showed well-deifned hypoecho lesions in 6 cases with penetrating vascular lfow signals in 2 cases and no vascular lfow signals in 6 cases by color Doppler imaging. In 3 cases by CEUS, all the hepatic focal nodulars showed variable arterial enhancement but wash-out in the portal venous and late phases. For diffuse type cases, hepatomegaly without nodule was showed in 11 cases. Vasular in liver showed normal in 8 cases and abnormal in 3 cases. For mixed type cases, hepatomegaly and multiple ill-deifned hypoechoic lesions with normal vascular in liver were showed in 1 case. Hepatosplenomegaly and abdominal lymphoadenopathies were identiifed in 11 cases. Conclusions The characteristics and the types of sonographic ifndings may be helpful in differentiating HL from other liver lesions.

Objective To study the accuracy and the clinical significance of sentinel lymph node biopsy (SLNB)after neoadjuvant chemotherapy for breast cancer.Methods A total of 90 patients with StageⅡorⅢbreast cancer and negative axillary node after neoadjuvant chemotherapy were enrolled in the study.Mapping proce- dure and SLNB were performed using methylene blue injected at the site of the primary breast cancer,followed by the axillary lymph node dissection.Results The sentinel lymph node(SLN)was successfully identified in 82 out of 90 patients(91.1%).The number of sentinel harvested nodes ranged from 1 to 4(average 1.6).The accuracy of SLNB to predict the axillary lymph node status was 93.9 %(77/82),the sensitivity,positive predictive value,nega- tive predictive value and false negative rate were 87.5 %(40/45),100 %,88.1% and 11.1%(5/45),respectively. The SLN identification rate tended to be higher and false negative rate tended to be lower in patients with T2 prima- ry tumor before neoadjuvant chemotherapy.Conclusion Our study indicated that SLNB after neoadjuvant chemotherapy in patients with StageⅡorⅢbreast cancer had a similar effect as SLNB in non-neoadjuvant studies. SLNB was considered to be able to accurately predict the axillary lymph node status in patients with T2 primary tu- mor before neoadjuvant chemotherapy.
