  • 医疗体制改革下的医院后勤经营化管理

    新一轮医药卫生体制改革(新医改)一系列措施的出台对医院经营管理带来了明显的影响,而医院后勤作为医疗服务的配套保障部门在新医改背景下也面临如何适应与发展的问题。在近几年的医院后勤改革中,社会化被认为是医院后勤服务质量和成本的根本解决之道。但在实践过程中,很多医院将社会化简单地理解为形式上社会化,即仅仅采用承包、外包、托管等形式上的转变而没有在管理上实现真正的社会化。就如医疗卫生服务不能纯粹商品化一样,医院后勤作为支持医院发展的重要保障体系也不能一概用纯粹市场化的方式去运作,医疗卫生服务的公平性、公益性在医院后勤管理中同样需要体现。所以,真正的社会化应该是在管理理念、方式、方法以及服务质量、价格与社会接轨的社会化,而这样的社会化必须改变传统的医院后勤管理理念与模式。医院后勤部门不应作为行政部门来运行管理,而是应作为一个医疗服务的延伸行业进行管理与经营,也就是所有医院后勤部门及业务应象企业一样进行经营,这正是四川大学华西医院近年来推行的后勤经营化管理理念。

  • SHORT-TERM EFFECTIVENESS OF SPINAL NAVIGATION WITH INTRA-OPERATIVE THREE-DIMENSIONAL-IMAGING MODALITY IN PEDICLE SCREW FIXATION FOR CONGENITAL SCOLIOSIS

    Objective To investigate short-term effectiveness of spinal navigation with the intra-operative three-dimensional (3D)-imaging modality in pedicle screw fixation for congenital scoliosis (CS). Methods Between July 2010 and December 2011, 26 patients with CS were treated. Of 26 patients, 13 patients underwent pedicle screw fixation using the spinal navigation with the intra-operative 3D-imaging modality (navigation group), while 13 patients underwent the conventional technique with C-arm X-ray machine (control group). There was no significant difference in gender, age, hemivertebra number and location, major curve Cobb angle, and Risser grade between 2 groups (P gt; 0.05). Operation time, operative blood loss, frequency of the screw re-insertion, and postoperative complication were observed. The pedicle screw position was assessed by CT postoperatively with the Richter’s standard and the correction of Cobb angle was assessed by X-ray films. Results All patients underwent the surgery successfully without major neurovascular complication. There was no significant difference in operation time, operative blood loss, and pedicle screw location between 2 groups (P gt; 0.05). A total of 58 screws were inserted in navigation group, and 3 screws (5.2%) were re-inserted. A total of 60 screws were inserted in control group, and 10 screws (16.7%) were re-inserted. There was significant difference in the rate of pedicle screw re-insertion between 2 groups (χ2=3.975, P=0.046). Patients of navigation group were followed up 6-24 months, and 6-23 months in control group. According to Richter’s standard, the results were excellent in 52 screws and good in 6 screws in navigation group; the results were excellent in 51 screws, good in 5 screws, and poor in 4 screws in control group. Significant difference was found in the pedicle screw position between 2 groups (Z= — 1.992, P=0.046). The major curve Cobb angle of 2 groups at 1 week and last follow-up were significantly improved when compared with preoperative value (P lt; 0.05), but there was no significant difference between 1 week and last follow-up (P gt; 0.05). No significant difference in correction rate of the major curve Cobb angle was found between 2 groups at last follow-up (t=0.055, P=0.957). Conclusion Spinal navigation with the intra-operative 3D-imaging modality can improve the accuracy of pedicle screw implantation in patients with CS, and effectually reduce the rate of screw re-insertion, and the short-term effectiveness is satisfactory.

  • Analysis and Management of Blood Pressure on Intraoperative Cortex Somatosensory Evoked Potential in the Surgery of Severe Scoliosis

    ObjectiveTo investigate the influence and management of blood pressure on intraoperative cortex somatosensory evoked potential (CSEP) in the surgery of severe scoliosis. MethodsFrom June 2009 to March 2012, CSEP monitoring during surgery of severe scoliosis were performed on 43 patients, in whom 4 had abnormal CSEP while blood pressure decline. There were 2 males and 21 females. The average age was 16.1 years. The average preoperative Cobb angle was 96.1° (88.7-107.5°). Latency and amplitude of cortical potentials were observed with the value of the latency extension more than 10% and peak amplitude reduction more than 50% defined as abnormality. The arterial blood pressure (ABP) was used to evaluate the intraoperative blood pressure. ResultThe incidence rate of bilateral CSEP wave abnormalities after blood pressure decline was 9.3% in the surgery of severe scoliosis. One case of CSEP abnormality occurred during the installing of pedicle screws; two cases during the Smith-Petersen osteotomy, and one case during the bone graft after correction. With the ABP dropping to about 92/57 mm Hg (1 mm Hg=0.133 kPa), the amplitude decreased 80% in 24-33 minutes. After the ABP increased to 113/75 mm Hg by treatment, the index was backed up normally in 5-10 minutes. There was no neurological complication after surgery. ConclusionA high incidence rate and significantly decreased amplitude of CSEP abnormality after blood pressure decline in the surgery of severe scoliosis are found. Intraoperative stable blood pressure should be maintained for patients with severe scoliosis. When the amplitude of CSEP decreases followed with blood pressure decline, blood pressure should be actively corrected by treatment, so that the CSEP may get back to normal as soon as possible.

  • Effect and mechanism of glycyrrhizin on glial scar formation after spinal cord injury in rats

    ObjectiveTo explore the effect and potential mechanism of glycyrrhizin (GL) by inhibiting high mobility group box 1 (HMGB1) on glial scar formation after spinal cord injury (SCI) in rats.MethodsSeventy-two female Sprague Dawley rats were randomly divided into sham group (n=12), SCI model group (SCI group, n=36), GL intervention group (SCI+GL group, n=12), and nuclear factor κB (NF-κB) inhibitor [pynolidine dithiocarbamate (PDTC)] intervention group (SCI+PDTC group, n=12). The SCI models of SCI group, SCI+GL group, and SCI+PDTC group were made by modified Allen’s method, the sham group was only exposed the spinal cord without any injury. First of all, Basso-Beattie-Bresnahan (BBB) score of hind limbs and slope test were performed in SCI group at 1, 2, and 3 weeks after operation; Western blot was used to detect the expressions of glial fibrillary acidic protein (GFAP) and HMGB1 proteins. Compared with the sham group, the most significant time point in the SCI group was selected for subsequent experiment, in which the most significant glial scar was formed. Then, behavioral tests (BBB score of hind limbs and slope test), histological observation of spinal cord tissue structure, Western blot detection of HMGB1, GFAP, and NF-κB proteins, and immunohistochemical staining observation of GFAP and chondroitin sulfate proteoglycan (CSPG) were used to explore the effect of GL on the formation of glial scar after SCI and its potential mechanism.ResultsThe BBB score and slope angle of the SCI group increased gradually with time, which were significantly lower than those of the sham group at each time point (P<0.05). Western blot detection showed that the relative expressions of HMGB1 and GFAP proteins in the SCI group at 1, 2, and 3 weeks after operation were significantly higher than those in sham group (P<0.05). The change was most obvious at 3 weeks after SCI, therefore the spinal cord tissue was selected for subsequent experiments at this time point. At 3 weeks after operation, compared with the SCI group, BBB score and slope angle of SCI+GL group significantly increased (P<0.05); the relative expressions of HMGB1, GFAP, and NF-κB proteins detected by Western blot and the expressions of GFAP and CSPG proteins detected by immunohistochemical staining significantly decreased (P<0.05); the disorder of spinal cord tissue by HE staining improved, inflammatory cell infiltration reduced, and glial scar formation decreased. At 3 weeks after operation, the expressions of NF-κB, GFAP, and CSPG proteins of the SCI+PDTC group significantly reduced when compared with the SCI group (P<0.05); and the expression of NF-κB protein significantly decreased and the expressions of GFAP and CSPG proteins significantly increased when compared with the SCI+GL group (P<0.05).ConclusionAfter SCI in rats, the application of GL to inhibit the expression of HMGB1 can reduce the expression of GFAP and CSPG in the injured spinal cord, then reduce the formation of glial scars and promote the recovery of motor function of the hind limbs, and GL may play a role in inhibiting glial scar through HMGB1/NF-κB pathway.

  • Effectiveness of three-dimensional printing artificial vertebral body and interbody fusion Cage in anterior cervical surgery

    ObjectiveTo evaluate the effectiveness of three-dimensional (3D) printing artificial vertebral body and interbody fusion Cage in anterior cervical disectomy and fusion (ACCF) combined with anterior cervical corpectomy and fusion (ACDF).MethodsThe clinical data of 29 patients with multilevel cervical spondylotic myelopathy who underwent ACCF combined with ACDF between May 2018 and December 2019 were retrospectively analyzed. Among them, 13 patients were treated with 3D printing artificial vertebral body and 3D printing Cage as 3D printing group and 16 patients with ordinary titanium mesh Cage (TMC) and Cage as TMC group. There was no significant difference in gender, age, surgical segment, Nurick grade, disease duration, and preoperative Japanese Orthopaedic Association (JOA) score, visual analogue scale (VAS) score, and Cobb angle of fusion segment between the two groups (P>0.05). The operation time, intraoperative blood loss, hospitalization stay, complications, and implant fusion at last follow-up were recorded and compared between the two groups; JOA score was used to evaluate neurological function before operation, immediately after operation, at 6 months after operation, and at last follow-up; VAS score was used to evaluate upper limb and neck pain. Cobb angle of fusion segment was measured and the difference between the last follow-up and the immediate after operation was calculated. The height of the anterior border (HAB) and the height of the posterior border (HPB) were measured immediately after operation, at 6 months after operation, and at last follow-up, and the subsidence of implant was calculated.ResultsThe operation time of 3D printing group was significantly less than that of TMC group (t=3.336, P=0.002); there was no significant difference in hospitalization stay and intraoperative blood loss between the two groups (P>0.05). All patients were followed up 12-19 months (mean, 16 months). There was no obvious complication in both groups. There were significant differences in JOA score, VAS score, and Cobb angle at each time point between the two groups (P<0.05). There was an interaction between time and group in the JOA score (F=3.705, P=0.025). With time, the increase in JOA score was different between the 3D printing group and the TMC group, and the increase in the 3D printing group was greater. There was no interaction between time and group in the VAS score (F=3.038, P=0.065), and there was no significant difference in the score at each time point between the two groups (F=0.173, P=0.681). The time of the Cobb angle interacted with the group (F=15.581, P=0.000). With time, the Cobb angle of the 3D printing group and the TMC group changed differently. Among them, the 3D printing group increased more and the TMC group decreased more. At last follow-up, there was no significant difference in the improvement rate of JOA score between the two groups (t=0.681, P=0.502), but the Cobb angle difference of the 3D printing group was significantly smaller than that of the TMC group (t=5.754, P=0.000). At last follow-up, the implant fusion rate of the 3D printing group and TMC group were 92.3% (12/13) and 87.5% (14/16), respectively, and the difference was not significant (P=1.000). The incidence of implant settlement in the 3D printing group and TMC group at 6 months after operation was 15.4% (2/13) and 18.8% (3/16), respectively, and at last follow-up were 30.8% (4/13) and 56.3% (9/16), respectively, the differences were not significant (P=1.000; P=0.264). The difference of HAB and the difference of HPB in the 3D printing group at 6 months after operation and last follow-up were significantly lower than those in the TMC group (P<0.05).ConclusionFor patients with multilevel cervical spondylotic myelopathy undergoing ACCF combined with ACDF, compared with TMC and Cage, 3D printing artificial vertebrae body and 3D printing Cage have the advantages of shorter operation time, better reduction of height loss of fusion vertebral body, and maintenance of cervical physiological curvature, the early effectiveness is better.
