ABSTRACT
Objective To analyze and assess the postoperative motor function in children with spastic cerebral palsy (SCP) by surface electromyography (sEMG) and joint angle. Methods Sixteen children with SCP were involved in this study. The sEMG of rectus femoris, biceps femoris, semitendinosus, tibialis anterior, lateral gastrocnemius and medial gastrocnemius muscles and joint angles of the hip, knee and ankle during straight walking were collected preoperatively and postoperatively. In every gait phase, the mean values of joint angles, root mean square and integrated electromyography of sEMG were calculated, to evaluate muscle strength and muscular tension quantitatively. Results The muscle tension of lower limbs was significantly decreased (P<0.05). The muscle strength of rectus femoris and biceps femoris was decreased in the swing phase. At the midswing and terminal swing phase, the strength of tibialis anterior increased significantly (P<0.05). The flexion angle of hip and knee decreased significantly (P<0.05). The dorsiflexion angle of ankle increased significantly (P<0.05), and the varus angle decreased significantly (P<0.05). Conclusions After operation, the crouching gait and clubfoot were improved positively. Therefore, the motor function of children was improved. Combining sEMG and joint angle can evaluate the muscle function of patients quantitatively, and it also can provide references for clinical diagnosis.
ABSTRACT
Objective To evaluate the clinical indications,complications and curative effects of external fixation combined with limited internal fixation in the treatment of adolescents distal tibial fracture involving the metaphysis.Methods From February 2013 to June 2017,18 adolescent patients of distal tibial fracture involving stem epiphyseal in Luzhong Hospital of Beida Care were treated with external fixator combined with limited internal fixation.All 18 cases were closed fractures,according to Salter-Harris classification:type Ⅱ 8 cases,type Ⅲ 8 cases,type Ⅳ 2 cases.The fracture healing time,postoperative patients治疗中的应用
ABSTRACT
NO is an important signal factor existing in expiratory air of normal person.Different kinds of airway inflammation can cause the increase of NO,especially eosinophilic inflammation.Fractional exhaled nitric oxide(FENO) can result in airway inflammation,which is noninvasive,repeatable and easily performed.It can be very helpful in the diagnosis and differential diagnosis of airway symptoms such as recurrent wheezing and chronic cough.It can also help determine the state of the disease and prognosis.It is a very useful tool in the assessment and management of airway diseases,especially asthma.
ABSTRACT
BACKGROUND: Artificial nerve grafts of human hair keratin are a kind of biological products. It has low antigenicity,absorbability and stimulation to nerve fiber growth following specific biochemistry. It is hoped to have better effect than otherartificial nerve grafts. OBJECTIVE: To investigate the anatomy and histocompatibility of artificial nerve grafts of the human-hair keratin, and toobserve its effects on the repair of peripheral nerves. DESIGN, TIME AND SETTING: Randomized, controlled, animal experiment. The study was performed at the Animal CentralLaboratory of Affiliated Hospital of Qingdao University Medical College between November 2006 and June 2008. MATERIALS: Artificial nerve grafts of human hair keratin is a compound of human hair processed by specific controlledbiochemistry based on ground substance, embedded with a layer of biological membrane. It has low antigenicity, absorbabilityand stimulation to nerve fiber growth following specific biochemistry. METHODS: Eighteen Wistar rats were randomly divided into three groups. The sciatic nerve, 10 mm, was removed andtransplanted with human-hair keratin graft, skeletal muscle and untreated hair, respectively.MAIN OUTCOME MEASURES: The characteristics of histomorphology and anatomy were observed at 8, 12, 24 weeks afterthe surgery. RESULTS: White tissues appeared between the broken ends of the sciatic nerve at 8 post-operative week in the graft group,and appeared in the graft space in human-hair keratin at the 12th week. At the 24th week, a large amount of infantile myelinatednerve fibers were observed under optical microscope regenerating around the human hair, which was partially degraded andabsorbed. Schwann cells were observed under an electron microscope and myelinization. CONCLUSION: The artificial nerve grafts of the human-hair keratin are well compatible with the body tissues, and couldinduce nerve regeneration.
ABSTRACT
The fact that incision inflammation ratio is related to the time of preoperative skin preparation was explored.227 cases made skin preparation a day or two hours before surgical operation were analysed prospectively in this study.There is statistical significant difference between the two periods of preoperative skin preparation:the second (two hours before surgical operation) can greatly lower the ratio of incision inflammation.
