OBJECTIVETo investigate the effect of vascularized composite flap with iliac crest and nternal oblique muscle of abdomen for half mandibular reconstruction.

METHODSFrom July 2009 to Sept. 2013, 14 cases with half mandibular defect after tumor resection were treated with composite flap of iliac crest and internal oblique muscle of abdomen pedicled by deep circumflex iliac vessels. During operation, one group performed tumor resection and got the recipient area vessels ready for anastomosis. The other group performed harvesting of composite flap. Then the flap was trimmed and fixed to construct the defect with vessel anastomosis.

RESULTSAll the 14 composite flaps survived with local infection only in 1 case. The size of harvested iliac crest ranged from 6 cm x 3 cm to 9 cm x 3 cm. The size of harvested internal oblique muscle of abdomen ranged from 5 cm x 4 cm to 7 cm x 5 cm. The patients were followed up for 6 months to 26 months (mean, 13 months) with satisfactory results and no complication. Mandibular panoramic radiographs showed new bone formation and good union.

CONCLUSIONSVascularized composite flap with iliac crest and internal oblique muscle of abdomen has the advantages of abundant bone volume, as well as soft tissue reconstruction in one stage. The reconstructed mandible can attain normal function and appearance.

Objective To investigate the serum levels of uric acid (UA) in bipolar disorder patients and their clini?cal significance. Methods Serum levels of UA was measured in 126 bipolar disorder patients including 77 mania pa?tients and 49 depression patients, 69 first-episode schizophrenic patients and 126 healthy controls (control group). Bipo?lar disorder patients was assessed by using the Young Mania Rating Scale (YMRS) and the Hamilton Depression Scale (HAMD). Results The serum UA levels were significantly higher in bipolar group [(349.34 ± 107.21) μmol/L] than in schizophrenic group [(319.71±84.48)μmol/L] and in control group [(280.94±71.90)μmol/L] (P<0.01). There were signifi?cant differences in serum UA levels between manic episode and depressive episode [(366.45 ± 104.01) μmol/L vs. (322.45±107.69)μmol/L]. The serum UA levels were higher in both manic episode and depressive episode groups than in control group (P<0.01). The serum UA levels was not significantly different between patients with and without medication (P>0.05). Correlation analysis indicated that the correlation of serum UA levels with YMRS scores and HAMD scores was not significant in bipolar disorder patients (P>0.05). Conclusions Patients with bipolar disorder has elevated serum uric acid levels which may be a biomarkers of bipolar disorder.

OBJECTIVE:To investigate the prognosis of coronary heart disease complicated with heart failure patients abandon-ing percutaneous coronary intervention (PCI) and receiving drug comprehensive therapy. METHODS:From Dec. 2010 to Jul. 2012,217 patients with coronary heart disease complicated with heart failure in our hospital were divided into operation group (105 cases) and non-operation group (112 cases). Based on routine treatment,operation group was given aspirin combined with clopidogrel before and after PCI,and non-operation group was given aspirin combined with clopidogrel all the time. The patients were followed up regularly during discharging from hospital to May 2015 by outpatient,telephone and coronary angiography re-checking,lasting for 24-38 months. Death cases,readmission and revascularization again caused by main adverse cardio-cerebrovas-cular events were recorded during follow-up period. RESULTS:7 cases and 8 cases in operation group and non-operation group did not accept follow-up;median follow-up time was 33 months and 32 months,respectively. Case number of myocardial infarction, heart failure and death in non-operation group was more than operation group,with statistical significance (P<0.05). 94 patients survived in operation group in 3 years,with survival rate of 95.9%;66 in non-operation group,with survival rate of 63.5%;with statistical significance(P<0.05). The survival time of non-operation group was shorter than that of operation group,with statistical significance(P<0.05). CONCLUSIONS:Although we still cannot get the conclusion that PCI is a better treatment or drug therapy is better. But the survival rate of patients are not optimistic 3 years after abandoning PCI coronary heart disease patients with severe myocardial ischemia should choose PCI firstly.

Objective: To explore the relationship among cognitive flexibility, depression and eating attitude of adolescents and the influencing factors of eating attitude. Methods: A total of 1 231 subjects were assessed using general information questionnaire, Kutcher Adolescent Depression Scale 11 item(KADS-11), Cognitive Flexibility Inventory(CFI), Eating Attitude Test 26(EAT-26). Data were analyzed by independent sample t-test, univariate linear regression, spearman correlation analysis and Logistic regression. Results: There were significant differences in EAT 26 among adolescents between genders and between those with or without depression(P<0.01). Statistically significant differences were observed in CFI, flexible control and KADS 11 among adolescents with or without eating disorders(P<0.01). The scores of EAT 26 was negatively correlated with CFI (r=-0.19, P<0.01) and flexible control(r=-0.23, P<0.01). And there was a significant positive correlation between EAT 26 and KADS 11(r=0.23, P<0.01). Female(OR=2.40, 95%CI=1.87-3.23), depression (OR=1.76, 95%CI=1.35-2.29) and poor flexible control (OR=1.94, 95%CI=1.48-2.54) were risk factors for eating disorders. Conclusion Female, individuals with depressive symptoms or with poor flexible control ability are more likely to have eating disorders which need more attention.

Objective:To compare the clinical outcomes of percutaneous vertebroplasty (PVP) and the Vesselplasty for kümmell′s disease.Methods:A retrospective case-control study was used.The clinical data of 62 patients with kümmell′s disease were selected in Beijing Friendship Hospital, Capital Medical University, from January 2017 to January 2019. There were 19 males and 43 females, aged (70.94±7.69) years, with range from 60 to 85 years. The patients were divided into two groups according to different operation methods. The 36 patients treated by PVP and 26 patients treated by Vesselplasty were followed up at least one year after operation. The follow-up time was (17.55±4.22) months. The operation time, incidence of cement leakage, preoperative and postoperative Cobb′s angle, visual analogue score (VAS) 1 week and 1 year after operation were observed. The measurement data were expressed as mean±standard deviation ( Mean± SD), independent sample t-test was used for comparison between groups. The count data were expressed as percentage (%), chi-square test was used for comparison between groups. Results:All the operation was successfully completed. No serious complications such as paraplegia, bone cement allergy, pulmonary embolism were occurred. The operation time was no significant difference between the two groups ( P< 0.05). The incidence of cement leakag was 41.67% (15/36) in PVP group and 11.54% (3/26) in Vesselplasty group. The latter was significantly lower than the former, with statistically significant differences between the two groups ( P< 0.05). In PVP group, the Cobb′s angles of preoperation, postoperation 1 year and difference were (26.23 ± 5.62)°, (17.46 ± 3.01)° and (8.78 ± 4.62)°, respectively, in Vesselplasty group, they were (28.74 ± 6.68)°, (16.68 ± 2.79)° and (12.07 ± 5.72)°, respectively. Cobb′s angle of the two groups was significantly improved after operation. In the comparison between the groups, the improvement of the Cobb′s angle in the Vesseplasty group was better than that of the PVP group, and the difference was statistically significant ( P< 0.05). The VAS score in PVP group was (8.42±1.03) scores in preoperation, (3.06±1.01) scores in 1 week, (0.81±0.75) scores in 1 year. The VAS score in Vesselplasty group was (8.35±1.02) scores in preoperation, (2.88±1.11) scores in 1 week and (1.04±0.87) scores in 1 year. Compared with pre-operation, the VAS scores of the two groups decreased significantly at 1 week and 1 year after operation, and the difference was statistically significant ( P<0.05). There was no significant difference in VAS between groups 1 week after operation and 1 year after operation ( P>0.05). Conclusion:Vesselplasty can effectively control the flow and distribution of bone cement in the vertebral body, effectively reduce the leakage of bone cement, and better correct kyphosis.

Objective:To evaluate the clinical effect of interspinous process fusion (BacFuse) in the treatment of lumbar disc herniation (LDH) with rheumatoid arthritis (RA).Methods:A retrospective analysis of the clinical data of 50 patients with RA and LDH from May 2013 to June 2018 in department of orthopedics, Beijing Friendship Hospital, Capital Medical University was conducted. Among them, there were 9 males and 41 females, aged (66.60±4.23) years, with an age ranging from 54 to 84 years. According to different surgical methods, the patients were divided into posterior lumbar interbody fusion (PLIF) group ( n=26) and BacFuse group ( n=24). Operative time, intraoperative blood loss and operative complications of the two groups were observed. Oswestry disability index (ODI) and Japanese Orthopaedic Association (JOA) scores were used to evaluate the clinical effect at preoperative, 3 days of postoperative and the last follow-up. The measurement data were expressed as mean±standard deviation( Mean± SD), comparison between groups used t test and the count data were expressed as percentage(%), the chi-square test was used for comparison between the two groups. The clinical effect of the two groups were compared by repeated analysis of variance. Results:In the PLIF group, the operation time and bleeding volume were (174.62±55.59) min, (309.62±30.26) mL, respectively. In the BacFuse group, the operation time and bleeding volume were (71.25±12.96) min, (57.92±9.32) mL, respectively. The differences between the two groups were statistically significant ( P<0.05). The operative complications in the PLIF group (8 cases) was significantly higher than that in the BacFuse group (2 cases) , the difference between the two groups was statistically significant ( χ2 = 3.926, P=0.048). There were significant differences between every two scores among the preoperative, 3 days of postoperative and last follow-up in ODI of the PLIF group( F=760.231, P<0.001). The preoperative, 3 days of postoperative and last follow-up ODI scores of the BacFuse group were significant differences between every two scores ( F= 952.525, P<0.001). There were no significant differences in ODI scores between the two groups [( t=-1.13, P=0.263), ( t=0.706, P=0.483), ( t=0.389, P=0.699)]. There were significant differences between every two scores among the preoperative, 3 days of postoperative and last follow-up in JOA of the PLIF group( F=406.012, P<0.001). The preoperative, 3 days of postoperative and last follow-up in JOA scores of the BacFuse group were significant difference between every two scores ( F=457.760, P<0.001). There were no significant differences in JOA scores between the two groups [( t=0.825, P=0.414), ( t=1.909, P=0.062), ( t=1.086, P=0.283). Conclusions:Compared with PLIF, BacFuse has a similar clinical effect in the treatment of LDH with RA, but BacFuse is less invasive and has fewer postoperative complications. BacFuse is an effective minimally surgical method for the treatment of LDH with RA.

Objective:To compare the safety and efficacy of two different minimally invasive approaches to implant pedicle screw for the treatment of single-segment thoracolumbar spine fractures without nerve injury.Methods:This was a retrospective study. Eighty patients with mono-segmental thoracolumbar fractures treated with minimally invasive pedicle screw fixation at Beijing Friendship Hospital, Capital Medical University from January 2020 to June 2022 were included. There were 46 males and 36 females, the age was (45.93±7.91) years old, and ranged from 27 to 60 years old. They were divided into two groups according to different surgical techniques: percutaneous pedicle screw fixation group ( n=44) and Wiltse approach group ( n=36). The operative time, operative visible blood loss, hidden blood loss, total blood loss, fluoroscopy times, incision length, hospital time after surgery and ambulation time were compared. Visual analogue scale (VAS), Oswestry disability index (ODI), ratio of the vertebral anterior height, angle of injured vertebral endplate were recorded and compared between two groups before surgery and at 3 days, 6 months and 1 year after surgery. The accuracy of pedicle screw position and the facet joint violation rate were evaluated by using the postoperative CT scan. Perioperative related complications were investigated. Normally distributed numerical data were presented as mean ± standard deviation, and differences between the groups were compared using t-test. The counting data were expressed as percentages or rates and compared using χ2 test. Results:All patients were followed for a minimum of 12 months. There is no significant difference between the two groups in intraoperative visible blood loss, hospital time after surgery, ambulation time, postoperative VAS and ODI, ratio of vertebral anterior height and angle of injured vertebral endplate at 3 days after surgery, pedicle screw position accuracy and perioperative complications ( P>0.05). The operative time, hidden blood loss, total blood loss, intraoperative fluoroscopy times, facet joint violation rate in the percutaneous pedicle screw fixation group were remarkably higher than in the Wiltse approach group ( P<0.05). The ratio of vertebral anterior height in the percutaneous pedicle screw fixation group was dramatically lower than in the Wiltse approach group at 6 months and 1 year after surgery ( P<0.05). The postoperative injured vertebral endplate angle was higher in the percutaneous pedicle screw fixation group than that in the Wiltse approach group at 6 months and 1 year ( P<0.05). Conclusions:Both percutaneous pedicle screw fixation and Wiltse approach were safe and effective minimally invasive surgical procedures for the treatment of thoracolumbar fractures without neurological injury. The Wiltse approach can reduce fluoroscopy times and perioperative hidden blood loss, reduce the risk of facet joint violation, and maintain a better reduction than percutaneous pedicle screw fixation.

Objective:To investigate the risk factors for unsatisfactory early pain relief after percutaneous vertebroplasty (PVP).Methods:This was a retrospective cohort study, included 208 patients with osteoporotic vertebral compression fracture admitted to Beijing Friendship Hospital, Capital Medical University from January 2019 to March 2020. According to the early pain relief after PVP, they were divided into good pain relief group ( n=188) and poor pain relief group ( n=20). Influence factors were record and compare, including the gender, age, preoperative lumbar bone density, body mass index, number of fractured vertebral bodies, degree of fracture compression, operation time, bone cement leakage, bone cement dispersion, thoracolumbar fascia injury, sarcopenia, and Hospital Anxiety and Depression Scale (HADS) score and visual analogue score of pain between the two groups. Measurement data were expressed as mean ± standard deviation ( ± s), and independent samples t-test was used for comparison between groups; the Chi-square was used for comparison of count data between groups. Univariate and multivariate Logistic regression analysis were used to investigate the independent risk factors for poor early pain relief after PVP. Results:All patients underwent surgery successfully, without serious complications such as cement embolism, cardio-cerebrovascular accident, epidural hematoma, spinal cord and nerve injury. There were no significant differences in operation time, bone cement leakage and bone cement diffusion between the two groups ( P>0.05). The statistical results showed that compared with the good pain relief group, the patients with poor pain relief group had lower preoperative lumbar bone density ( t=2.35, P=0.020), higher proportion of thoracolumbar fascial injury ( χ2=8.66, P=0.003) and sarcopenia( χ2=7.15, P=0.007), higher preoperative HADS score ( t=2.51, P=0.013). Univariate and multivariate Logistic regression analysis showed that lower preoperative bone density, higher preoperative HADS score, and higher proportion of thoracolumbar fascia injury and sarcopenia were independent influencing factors for poor early pain relief after PVP. Conclusions:The poor early pain relief after PVP is associated with lower preoperative lumbar bone density, preoperative complications such as thoracolumbar fascial injury, sarcopenia, and preoperative anxiety. Effective prevention of the above factors should be taken during the perioperative period to avoid serious complications.

Objective: To compare the clinical outcomes of unilateral extreme extrapedicular puncture versus bilateral transpedicular puncture in percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fracture. Methods: A prospective cohort study was performed. Ninety-seven patients of osteoporotic vertebral compression fractures treated were selected from January 2016 to January 2018 in Beijing Friendship Hospital, Capital Medical University. There were 36 males and 61 females, aged (72.19±7.41) years, with an age range of 60-80 years. All the patients underwent PVP with different puncture methods were divided into unilateral puncture group(n=52) and bilateral puncture group(n=45). PVP was performed in the unilateral extreme extrapedicular puncture group by unilateral puncture of the pedicle, and PVP was performed by bilateral puncture of the pedicle in the bilateral transpedicular puncture group. All patients completed at least one year of follow-up after operation. The operation time, fluoroscopy times, cement volume, incidence of cement leakage, visual analogue score (VAS) of 1 week and 1 year after operation were observed. The measurement data were expressed as mean±standard deviation (Mean±SD), count data were expressed as percentage, the independent sample t test and the χ² test were used for comparison between groups, and the paired t test was used for comparison within the group. Results: The operation was successfully completed in both groups. No serious complications such as paraplegia, bone cement allergy, pulmonary embolism were occurred. In the unilateral puncture group, the operation time were (21.90±3.16) min, the fluoroscopy times were (15.46±2.86) times, the cement volume were (3.47±0.41) ml and the incidence of cement leakage was 44.23% (23/52), in the bilateral puncture group, the operation time were (31.64±6.90) min, the fluoroscopy times were (23.31±2.39) times, the cement volume were (4.66±0.61) ml and the incidence of cement leakage was 68.89% (31/45). The operation time, fluoroscopy times, cement volume and incidence of cement leakage of unilateral puncture group were significantly less than those of bilateral puncture group. The difference was statistically significant (P< 0.05). The VAS score in unilateral puncture group was (8.18±0.77) scores in preoperation, (3.39±0.69) scores in 1 week, (1.07±0.90) scores in 1 year. The VAS score in bilateral puncture group was (7.93±0.92) scores in preoperation, (3.14±0.83) scores in 1 week and (0.90±0.82) scores in 1 year. Compared with pre-operation, the VAS scores of the two groups decreased significantly at 1 week and 1 year after operation, and the difference was statistically significant (P<0.05). However, there was no significant difference in VAS between groups at 1 week after operation and 1 year after operation (P>0.05). Conclusions Compared with bilateral transpedicular puncture, PVP through unilateral extrapedicular puncture can achieve the same clinical effect. However, the latter can significantly reduce the operation time, the cement volume, fluoroscopy times and the incidence of cement leakage.
