Hemi-arthroplasty performed in a 109-year-old patient with intertrochanteric fracture: A case report / 中华创伤杂志(英文版)

The mortality of conservative treatment and the risk resulting from operation for elderly patients with femoral intertrochanteric fractures are high. Safety in the perioperative period and quicker recovery should be placed at the top priority for elderly patients with hip fractures. We reported a case of 109-year-old female patient with intertrochanteric fracture who has undergone the hemiarthroplasty in our center recently. With sciatic nerve and lateral cutaneous nerve block anesthesia, she was offered the artificial femoral head replacement in the lumbar plexus block after sufficient preoperative preparation. The surgery went well with minimally invasive cut, and the patient's recovery was satisfactory.

Clinical features of tracheobronchial foreign bodies in children / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the clinical features of tracheobronchial foreign bodies in children and to provide a basis for feasible preventive measures.</p><p><b>METHODS</b>A retrospective analysis was performed on the clinical data of 114 children with tracheobronchial foreign bodies confirmed by fiberoptic bronchoscopy between February 2012 and February 2013.</p><p><b>RESULTS</b>The majority (71.9%) of children with tracheobronchial foreign bodies were younger than three years old, and the male-to-female ratio was 2:l. The proportion of cases in winter was higher than that in summer. The incidence of tracheobronchial foreign bodies was significantly higher among rural children than among urban children. The positive rate of CT varied significantly for tracheobronchial foreign bodies at different sites, and the patients with tracheal foreign bodies had a significantly lower positive rate of chest CT than patients with foreign bodies in the left and right main bronchi (P<0.01). The misdiagnosis rate in children with a history of aspiration of foreign bodies was significantly lower than in children without one (P<0.01).</p><p><b>CONCLUSIONS</b>Health education related to the prevention of tracheobronchial foreign bodies in children should be conducted primarily in rural areas. Tracheobronchial foreign bodies are common in children younger than three years old. Bronchoscopy should be performed early for suspected cases of tracheobronchial foreign bodies.</p>

<p><b>OBJECTIVE</b>To evaluate early clinical outcome after arthroscopic treatment of elbow dysfunction.</p><p><b>METHODS</b>From September 2007 to December 2009, 21 patients with elbow dysfunction were treated with an arthroscopic procedure. All patients had chronic history of elbow dysfunction. Extension lag was 18.2° (10° - 25°) combined with pain. All patients underwent five-portals arthroscopic release and debridement. Postoperative care including anti-infection, rehabilitation and prophylaxis of myositis ossificans were prescribed. All elbows were assessed for increase in ROM and Mayo assessment before and after surgery. Mayo score assessment: ≥ 90 points, excellent; 75 - 89 points, good; 60 - 74 points, common; < 60, bad. Complications were evaluated.</p><p><b>RESULTS</b>At an average follow-up of 19.7 months (6 - 29 months), all patients had improvement of extension and relief of pain. The average lag of extension was 2.4° (0° - 5°). Pre-operative Mayo assessment: good, 13 patients; common, 5 patients; bad, 3 patients. Post-operation Mayo assessment: excellent, 17 patients; good, 4 patients; common, 0 patients; bad, 0 patient. There was no complication in this case serial.</p><p><b>CONCLUSIONS</b>Arthroscopic surgery can minimize trauma and bleeding, and reduce complications. Combined with reasonable rehabilitation, arthroscopic surgery can improve elbow function and appears to be satisfactory management.</p>

Arthroscopically assisted treatment for Schatzker type I-V tibial plateau fractures / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To report the clinical outcome of arthroscopically assisted treatment for tibial plateau fractures.</p><p><b>METHODS</b>A total of 39 patients with tibial plateau fractures were treated by arthroscopic fixation from February 2002 to December 2005, including 11 patients with bony avulsion of the anterior cruciate ligament and 19 with meniscal injury. There were 4 cases of type I fracture, 12 type II, 9 type III, 12 type IV and 2 type V according to Schatzker criteria. Firstly, the combined injuries were treated. Then the plateau fractures with the displacement over 3 mm or more were reduced and fixed. Finally, the internal fixation was observed by X-ray equipment. Postoperative management was early motion and delayed weight bearing.</p><p><b>RESULTS</b>All the fractures healed in 3 or 4 months. All patients were followed up for 1 to 5 years after operation. No case had severe complications, such as poor wound healing, infection, osteofascial compartment syndrome and osteoarthritis. According to the Rasmussen scoring system, 36 cases obtained excellent or good results and the other 3 cases had moderate clinical results. The average score was 26+/-3.</p><p><b>CONCLUSIONS</b>As an adjuvant treatment of intraarticular fractures such as tibial plateau fracture, arthroscopy has many advantages. It can treat associated intraarticular soft tissue components, visualize the chondral surface reduction, lavage the hematoma and smaller loose fragments, decrease soft tissue dissection, reduce the risk of scarring and promote rapid recovery.</p>

Bone-patellar tendon-bone graft in anterior cruciate ligament reconstruction: allograft versus autograft / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the clinical result of arthroscopic anterior cruciate ligament (ACL) reconstruction with either allo- or auto- bone-patellar tendon-bone (B-PT-B) grafts.</p><p><b>METHODS</b>From February 2002 to January 2006, 142 of 187 cases of ACL ruptures who received ACL reconstruction with B-PT-B grafts were studied retrospectively. There were 93 male and 49 female whose age was from 15 to 57 years (mean 26 years). Patients were divided into 2 groups by graft selection: 38 patients with autograft and 104 with allograft. Clinical results were evaluated according to IKDC, Lysholm, Irgang and Larson scales. Sub-items of scales such as pain, swelling and laxity were specifically evaluated.</p><p><b>RESULTS</b>All of the patients were followed up with an average of 24 months (range from 6 to 43 months). All grafts were radiographically in good position at the time of follow-up. KT-1000 examination of affected knee showed less than 3 mm anterior translation difference compared with contralateral one's. Allograft group: 85 patients got normal IKDC score (81.7%). Lysholm score 82.8 +/- 8.5, Irgang score 79.2 +/- 7.3, Larson score 86.7 +/- 3.1. Autograft group: 29 patients got normal IKDC score (76.3%). Lysholm score 84.6 +/- 9.5, Irgang score 79.5 +/- 7.6, Larson score 88.9 +/- 6.8. No significant statistical difference was found between the 2 groups in the comprehend scale (P>0.05).</p><p><b>CONCLUSIONS</b>Both autograft and allograft group achieve good results, and the allograft B-PT-B could provide the similar clinical result as autograft, the preliminary result of allograft reconstruction might indicate predictable result in the future.</p>

Influence of fluorescent protein expression on the proliferation of NIH3T3 cells in vitro / 中华烧伤杂志

<p><b>OBJECTIVE</b>To investigate the influence of fluorescent protein expression on the proliferation of murine NIH3T3 cells, so as to provide a theoretical basis for cell tracing technology.</p><p><b>METHODS</b>NIH3T3 cells were cultured in vitro, and were randomly divided into control, pLEGFP-N1 (with transfection of pLEGFP-N1 retroviral vector), pEGFP-N1 (with transfection of pEGFP-N1 vector) and pDsRed2-C1 (with transfection of pDsRed2-C1 vector) groups. Then the cells were screened by G418 for 3 weeks. The changes in cell adhesive rate were observed and the population doubling times was determined by growth curve.</p><p><b>RESULTS</b>There was obvious fluorescent protein expression in the transfected NIH3T3 cells after G418 selection, and the highest percentage of labeled NIH3T3 cells was found in pLEGFP-N1 group. The population doubling time in pDsRed2-C1 (40.3+/-0.7 h) , PEGFP-N1 (39.6 +/- 0.6 h) and pLEGFP-N1 (36.5 +/- 0.7 h) groups was evidently longer than that in control (27.9 +/- 0.6 h, P < 0.01), with high adhesive rate in each group.</p><p><b>CONCLUSION</b>The expression of fluorescent protein exhibited some inhibitory effect on the proliferation of NIH3T3 cells in vitro. Since the inhibitory effect by retroviral vector was weaker compared with eukaryotic vector, it should be the first choice for fluorescent protein labeling during cell transplantation.</p>
