Spine surgery is a branch of science bridging neurosurgery and orthopedics.In our country,spinal neurosurgery started relatively late and its development is unbalanced regionally despite rapid development in recent years.In this paper, we make an objective evaluation of the development and present situation of spinal neurosurgery in China and its existing problems.We also introduce some theoretical knowledge about stability of the spine as well as some methods commonly used in clinic to protect and reconstruct spinal stability. We urge neurosurgeons to pay more attention to the learning of and research on spinal stability and biomechanics,and perform spinal surgery vigorously and assuredly.

Objective To evaluate the impact of sleep-disordered breathing(SDB)on the quality of life(QOL)in children with SDB and investigate the value of tonsillectomy and adenoidectomy in improving their QOL.Methods Questionnaire of disease-specific quality of life for children with obstructive sleep apnea with 18 items(OSA-18)was used to evaluate QOL in 168 children with SDB within four weeks before and six to 12 months after surgical operation,and correlation between OSA-18 scores to apnea hypopnea index(AHI)and minimum oxygen saturation(MiO2)in 62 of them was evaluated with polysomnography(PSG),with 50 healthy children without snoring as controls.Results Overall scores of OSA-18 in children of SDB group before surgical operation were significantly higher than those in children of control group(t=15.12,P＜0.01).and QOL was seriously affected in 30.4 percent of the children with SDB.Scores of OSA-18 correlated to AHI and MiO2 before surgical operation.QOL was improved significantly in 73.8 percent of children with SDB after tonsillectomy and adenoidectomy.Conclusions SDB has obvious impact on pediatric QOL,which can be improved by tonsillectomy and adenoidectomy.There exists significant correlation between OSA-18 scores and objective indicators of PSG,and the former can be used as clinical diagnosis for SDB in children and as quantitative evaluation for the effectiveness of intervention.

OBJECTIVE: To promote rational use of non-antimicrobials based on Intelligent Monitoring System for Dosage and Frequency of Drugs.METHODS: Base on the information system of hospital,dosage and frequency of drugs were collected from Intelligent Monitoring System for Dosage and Frequency of Drugs and connected with patients’ ages,weights,body surface areas and renal functions.1 315 hospitalized prescriptions of non-antimicrobials were randomly collected from our hospital one day.RESULTS: There were 200 warnings of overdosage each time and moderate frequency,91 warnings of overdosage each time and inadequate frequency,43 warnings of moderate dosage each time and inadequate frequency,41 warnings of moderate dosage each time and excessive frequency,15 warnings of inadequate dosage each time and moderate or inadequate frequency for drugs that needn’t be adjusted according to age and renal functions.There were 11 warnings of overdosage and excessive frequency for drugs that should be adjusted according to patients’ age and renal function.CONCLUSION: This kind of connection is practical,when prescriptions of non-antimicrobials which violate the rules of dose and (or) frequency are identified by system.But the significance of Intelligent Monitoring System for Dosage and Frequency of Drugs should be proved by practice.

Objective To develop a fast shimming method for permanent magnet MRI system. Methods Peak location method (PLM) was improved by calculating the eddy current effect, and the time deviation was replaced by their phase to increase the precision. Results Experiment showed that the new method took less than 45 s, which was 3 times faster than conventional method while providing the same homogeneity. The result of PLM satisfied the requirement of homogeneity. Conclusion This new method can significantly improve the homogeneity in a short time and satisfy further fast pulse sequence development on 0.5T permanent magnet MRI system, which can be generalized for any permanent magnet first order shimming.

Objective To investigate the effects of comprehensive pelvic floor rehabilitation program on pelvic floor muscle strength, female sexual function index (FSFI) score and sexual satisfaction scale for women (SSS-W) score in patients with perimenopausal female sexual dysfunction. Methods The clinical data of 120 patients with perimenopausal female sexual dysfunction were retrospectively analyzed, and all the patients were treated with estrogen and progesterone replacement therapy. Among the patients, 80 patients were treated with Kegel training program (control group), and 80 patients were treated with Kegel training program combined with comprehensive pelvic floor rehabilitation program (treatment group). The pelvic floor muscle strength, FSFI score, SSS-W score, incidence of algopareunia and sexual life frequency were compared between 2 groups. Results The pelvic floor muscle strength after treatment in treatment group was significantly better than that in control group. The Ⅲ,ⅣandⅤgrade of pelvic floor muscle strength in treatment group was in 5, 42 and 33 cases, and that in control group was in 21, 47 and 12 cases, and there was statistical difference (P<0.05). The FSFI scores and SSS-W scores after treatment in treatment group were significantly higher than those in control group:(32.24 ± 3.70) scores vs. (28.51 ± 2.95) scores and (139.80 ± 16.17) scores vs. (122.33 ± 13.75) scores, and there were statistical differences (P<0.05). The incidence of algopareunia after treatment in treatment group was significantly lower than that in control group:10.00%(8/80) vs. 55.00%(44/80), and there was statistical difference (P<0.05). The sexual life frequency after treatment in treatment group was significantly better than that in control group, the 0, 1, 2 and≥3 times/month of sexual life frequency in treatment group was in 0, 8, 20 and 52 cases, and that in control group was in 5, 34, 24 and 17 cases, and there was statistical difference (P<0.05). Conclusions Comprehensive pelvic floor rehabilitation program in patients with perimenopausal female sexual dysfunction can efficiently promote the recovery process of pelvic floor muscle strength, improve FSFI score and SSS-W score, and increase the degree of sexual satisfaction.

Objective To study the effect of methadone maintenance treatment(MMT) on reducing HIV infection among injecting drug users(IDUs) in Yueyang city of Hunan province.Methods Local IDUs were provided with MMT along with peer education and behavior interventions,and they were tested for HIV antibody to evaluate the effect of MMT after one year treatment.Results Of the 113 IDUs who were negative at the entry,none turned to be positive after one year treatment and the negative partners of 22 IDUs with positive HIV antibody remained negative one year later,and the negative rate of urine test maintained at 76.10%.Conclusion MMT combined with peer education and behavior interventions will decrease the use of heroin,prevent HIV infection among IDUs and reduce their partners' susceptibility to HIV.

Objective To investigate whether scores of epworth sleepiness scale (ESS) assessing daytime sleepiness were associated with sleep apnea syndrome(SAS)combined with cerebral vascular disease and ESS could be used to predict cerebral vascular disease occurrence.Methods A group of 62 SAS combined with transient ischemic attack(TIA), a group of 53 SAS with combined hypertension and the other group of 61 SAS combined without other diseases were monitored by polysomnography(PSG), daytime sleepiness of these SAS patients were assessed by ESS at the same time. Results Compared to SAS combined without other diseases, those SAS combined with TIA and hypertension patients had significant higher scores of ESS,apnea/hypopnea index (AHI) and micro-arousal index(MAI)(all P
