ABSTRACT
Gauze packing and drainage is a routine treatment for various types of fistula and sinus pressure ulcers. Because the external orifice of pressure ulcer or fistula is relatively small and the sinus deep, the conventional gauze packing has many drawbacks. Under the situation the operator is not skillful enough and no appropriate tools, it is necessary to pull the external orifice by tweezers to dilate the sinus and perform gauze packing and drainage, which brings great pain to patients, possibly leading to wound enlargement and delayed healing. At present, there is lack of auxiliary tools to improve gauze packing. Therefore, we developed and designed a gauze filler for packing and drainage of various kinds of fistula and sinus pressure ulcers, the device has the following advantages: good drainage effect, simple operation, low cost, safety and effectiveness. It not only improves the comfort of patients, reduces the number of dressing changes, reduce the number of dressing changes, shorten the hospitalization time and pay expense, but also reduces the burden of medical workers thus it is worthwhile to popularize and apply the newly designed gauze filler in clinical practice.
ABSTRACT
Objective@#To explore the effect of reconstructing the finger extension function by using partial flexor digitorum profundus tendon transposition.@*Methods@#Twelve patients were treated by using the partial proximal end of the tendon core of flexor digitorum profundus tendon regionⅠand part of region Ⅱ to cut off to the base of the distal digital phalanx, and puncturing at the end of the phalanx with a 2.0 drill. The tendon strips were pierced to the back overlap sutured to the proximal end of the avulsion of the extensor tendon .@*Results@#In 3-18 month follow-up, the average follow-up duration was 10.6 months. According to Dargan function evaluation method, 12 cases were excellent and one case was poor.@*Conclusions@#The method of reconstructing the extensor tendon by partial flexor deep tendon is a reliable method for the treatment of Mallet finger.
ABSTRACT
Age estimation was one of the important and difficult contents in forensic medicine research and practice. Age estimation was mainly based on bone age and dental age in present. However, the errors were large, and it was influenced by other factors. In recent years, following with the development of molecular biology theories and techniques, researchers have found that some cellular and molecular levels were related to age. In this review, the research progress of molecular biology in age estimation was reviewed.
ABSTRACT
Bone marrow mesenchymal stem cells (BMSCs) is a good seed cell,and it is widely used in intervertebral disc tissue engineering research.The improvement of cellular scaffolds,cell factors and further understanding of intervertebral disc (IVD) cell pathophysiology and BMSCs biology have laid the foundation for cell-based therapies for IVD degeneration.However,BMSCs repairing IVD is still in the early stage of research,at present there are still many problems,one of the most prominent is the survival of transplanted cells.This review mainly introduces the current research status of BMSCs in IVD tissue engineering.
ABSTRACT
ObjectiveTo explore the ideal minimally invasive surgical method for degenerative lumbar spine stenosis.MethodsFrom March 2008 to August 2010,73 cases with lumbar spinal stenosis underwent minimal invasive surgery were retrospectively analyzed.The patients were divided into different groups by clinical features,imaging manifestations,and concurrent diseases.The minimal invasive surgical methods were chosen according to the classification.Operation time,intra-operative bleeding,and complications were recorded.The lumbar function was evaluated by Oswestry disability index (ODI),and the clinical results were assessed by JOA pre- and postoperatively.ResultsMinimal invasive surgery was completed in all cases,which included 25 cases with bilateral decompression and 48 cases with unilateral approach for bilateral decompression.Twenty-three cases used interbody fusion and percutaneous pedicle screw fixation after decompression.Intraoperative blood loss and operation time were related to surgical methods.One case was complicated with dural tear.Cage was inserted into upper vertebral body during interbody fusion in 1case with osteoporosis,removed the cage and implanted bone fusion.Incisions of 3 cases were poor healing after surgery.The average follow up time was 13 months(range,10-35).JOA score and ODI before surgery were 9.2±5.1 and 62.3％±18.5％ respectively; while 6 months after surgery,JOA score and ODI were 23.5±7.2 and 18.4％±6.4％ respectively.JOA score and ODI showed statistically significant improvements after operation(P＜0.01).Twenty-two cases got solid fusion at the final follow-up.ConclusionTreatment of lumbar spinal stenosis by minimal invasive surgery has satisfactory surgical outcomes,but the proper minimal invasive strategy should be chosen according to specific patients,surgeons and hospitals.
