BACKGROUND: Microarc oxidation (MAO) is a break-through anodyzing technology for forming oxide films on valve metal.Use of this technology allows thick, porous oxide layers to be formed on the surface of pure titanium. Few biocompatibility reports using this treatment have been found.OBJECTIVE: The blood compatibility of a novel surface modified titanium substrata biomaterial using MAO was investigated.DESIGN: Positive and negative control, contrast observation and gold standard control.SETTING: Wuhan Union Hospital.MATERIALS: A healthy male adult New-Zealand rabbit, weighing 2.5 kg and ordinary grade, was selected in this study.Pure titanium sticks TA1 (Baoji Yingnaite Non-ferrous Metal Co., Ltd.), MAO-Ti and 20 g/L potassium oxalate were also selected in this study.METHODS: The study was carried out in the Laboratory of General Surgery, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology in May 2006. ① Materials: Titanium substrate of 10 mm in diameter and 2 mm in depth was put in an electrolyte which was quipped with deionized water, dibasic sodium phosphate, and ethanoic acid calcium for MAO treatment for 10 minutes. ② Groups: Three groups were analysed: test group, negative control group and positive control group. Test group: MAO-Ti was dipped in 10 mL saline; Positive control group: 10 mL deionized water was added in each tube; Negative control group: 10 mL saline was added in each tube. ③ Operation: Fresh whole blood was collected from rabbit and then mixed with the liquids in the three groups respectively after anti-coagulation. In addition, UV-Visible Spectrophotometer was used to evaluate the hemolytic ratio. A hemolytic ratio below or equal to 5% indicated that this novel material fitted the requirements. On the contrary, a hemolytic ratio higher than 5% proofed the existence of a hemolyzation.MAIN OUTCOME MEASURES: The hemolytic ratio of materials in three groups.RESULTS: The hemolytic ratio of the test group was 0.90%. The result indicated that this new material had no haemolysis effect.CONCLUSION: The material does not resolve red blood cells and is coincident with the international and governmental standard.

BACKGROUND:Anterior cervical discectomy and fusion surgery is a good choice for repair of degenerative cervical disc herniation, but it is reported that fusion can affect the exercise of cervical neighboring stages. Artificial disc replacement can not only play a role in mitigation of cervical disease neurological symptoms and signs, but also maintain stability and semental activity of cervical spine, and reduce secondary adjacent segmental degeneration.
These two methods which applied in cervical degenerative intervertebral disc herniation stil remain controversial. OBJECTIVE:To investigate the short-term effect of artificial cervical disc replacement and anterior cervical decompression and fusion for the treatment of single segmental cervical disc herniation. METHODS:Total y 48 patients with single segment radiculopathy or myelopathy cervical diseases induced by cervical disc herniation that required surgery and received a three-month fol ow-up were included and retrospectively analyzed. These patients were divided into replacement group (n=21) and fusion group (n=27) according to the different repair programs. Patients in the replacement group were subjected to Prestige LP cervical artificial disc replacement, and patients in the fusion group were subjected to disc fusion using interbody fusion cage of Johnson or al ogeneic fibularing. They were fol owed up at 1 week, 3, 6, 12, 24, 36 months after treatment. Complications were recorded during the fol ow-up. The pain of patients was evaluated using neck and upper limb pain visual analogue scale scores. The therapeutic effect was evaluated using Japanese Orthopaedic Association (JOA) score. The clinical symptoms improvement and daily functional status of patients after treatment were evaluated using cervical disability index. RESULTS AND CONCLUSION:During the final fol ow-up, the fusion rate in fusion group was 93%(25/27). Comparisons between groups:at the 1 week and final fol ow-up after treatment, the visual analog scale scores of neck and upper limbs and cervical dysfunction indexes were al lower than those before treatment;the Japanese Orthopaedic Association scores were higher than those before treatment (P<0.05). In the final fol ow-up, the visual analog scale scores of neck and upper limbs and cervical dysfunction index were al lower than those after one week of treatment, and the Japanese Orthopaedic Association scores were higher than those after one week of treatment (P<0.05). There were no significant differences in the above indicators at each time point between these two groups (P>0.05). The cervical activity and surgical segmental motion after cervical disc replacement were significantly higher than those in the fusion group;the difference was statistical y significant (P<0.05). There were no serious complications in these two groups. There was no significant difference in the incidence of complications between these two groups (P>0.05). These results suggest that the artificial cervical disc replacement and anterior cervical decompression and fusion for the treatment of single cervical disc herniation have the same effect in terms of patients’ symptoms mitigation. With respect to fusion technique, artificial disc replacement surgery has the advantage of maintaining cervical stability and activities of replacement segments.

BACKGROUND:In recent years, with the continuously improving of the fixation systems and technology, conducting anterior cervical decompression bone graft accompanying with anterior plate fixation have been accepted by most scholars, however, the complications related to this also appeared constantly. In view of this, the zero notch interbody fusion plate (Zero-P) has been approved for the clinical treatment of cervical degenerative disease. OBJECTIVE:To discuss the early application effect of Zero-p on anterior cervical decompression and fusion. METHODS:The study enrol ed 22 patients who underwent anterior cervical decompression and fusion with Zero-P between February and December 2014. The number of Zero-P implanted in the C3-4, C4-5, C5-6 was 1, 3 and 18 respectively. Pain and neurological improvement were evaluated using Visual Analog Scales score and Japanese Orthopaedic Association (JOA) score for al the patients after operation. The X-ray plain of lateral and flexion-extension lateral of cervical vertebra were shot. The degradation degree was judged based on the measurement results from the cervical lateral X-ray films about the ratio of cephalad and caudal adjacent intervertebral space to vertebral body height, and adjacent segments osteoarthritis situation. The abnormal activity at the surgical spaces was observed by the extension and flexion lateral X-ray plain. RESULTS AND CONCLUSION:Twenty-two patients obtained fol ow up for 10-28 months. 2 patients had dysphagia on the fourth day and the fifth day after operation (extremely mild). The symptom disappeared within 2 weeks after treatment. The Visual Analog Scales score was significantly lower compared with preoperation (P<0.05), the JOA score was significantly higher than that before operation (P<0.05) , the cervical Cobb angle was significantly higher than that before operation (P<0.05). There were no significant differences statistical y in comparison of the Visual Analog Scales score, JOA score and cervical Cobb angle at different time points after operation (P>0.05). In cephalad adjacent intervertebral space, 3 cases had developed hyperosteogeny (first level). In caudal adjacent intervertebral space, 1 had developed hyperosteogeny (first level). There was no significant difference in the hyperosteogeny between cephalad adjacent intervertebral space and caudal adjacent intervertebral space (P>0.05). There was no significant difference in the R value in cephalad adjacent intervertebral space and caudal adjacent intervertebral space between preoperation and postoperation (P>0.05). During the fol ow-up, no abnormal activity at the surgical spaces and implant displacement was observed. These results suggest that using Zero-p in the treatment of monosegmental disc disease has significant effect, can effectively improve the cervical curvature and establish good cervical stability. The incidence of postoperative dysphagia is low. The degeneration of adjacent segments after treatment was not increased in early stage.

Objective To study the pulmonary surfactant (PS) on prevention of neonatal respiratory distress syndrome (NRDS) in neonates delivered via caesarean section. Methods From selective cesarean section infants (gestational age 34-38+6 W), 80 cases whose test tube oscillation tests were negative and amniotic fluid pulmonary surfactant associated protein A (SP-A) concentrations were lower than <10μg/L, and were randomly divided into PS prevention group and control group, with 40 cases in each group. PS prevention group within 1 h of birth were administrated poractant alfa injection by endotracheal tube (dose 100 mg/kg), but the control group was not given special treatment, leaving only the observation. The incidence of NRDS, treatment status and clinical progression were compared between two groups. Results The incidence of NRDS in control group was 82.5%(33/40), in PS prevention group was 37.5%(15/40), and there was significant difference (P<0.05). The degree of NRDS in control group was more severe. The incidence rate of persistent pulmonary hypertension of the new-born (PPHN), pulmonary air leak, patent ductus arteriosus and oxygenation index above 25 mmHg (1 mmHg=0.133 kPa) in control group were significantly higher than those in PS prevention group (P<0.05). The time of mechanical ventilation, the time of oxygen inhalation, ratio of arterial partial pressure of oxygen (PaO2) before mechanical ventilation to fraction of inspired oxygen (FiO2), and costs of hospitalization in control group were significantly higher than those in PS prevention group (P<0.05). Conclusions PS prevention can reduce the incidence of NRDS of neonates delivered by elective caesarean section, can alleviate the symptoms of NRDS, shorten length of stay and reduce the cost of hospitalization.

This study examined the cytotoxicity of a new implant material modified by microarc oxidation technique. Cells on different surfaces of the implant were evaluated 2, 4 and 6 days after treatment. The results showed that cell attachment, cell morphology, and cell proliferation were influenced by the different surface treatments, and a significant increase in the osteoblast cell activity was observed on the porous MAO-Ti coating. Our results suggest that the porous MAO-Ti surface has a better biocompatibility and electrochemical performance than pure titanium surface.
