Objective To discuss perioperative features, operative approach and surgical effects of spinal tuberculosis in older patients. Methods Retrospective analysis was conducted to analyze the clinical data of 45 patients with spinal tuberculosis ranging in age from 61 to 78 years (average, 67 years). The lesion was located in thoracic vertebrae in 9 patients, thoracolumbar vertebrae in 14, lumbar in 16, and lumbosacral in 6. Preoperative Frankel grades were B in 7 cases, C in 21, D in 11 and E in 6. Among them, 21 had cardio-cerebrovascular disease, 10 had diabetes mellitus. With preoperative medicine and chemotherapy for 2-3 weeks, all patients were treated surgically. The surgical procedures included: 1) Posterior focus debridement, bone grafting and one-stage posterior transpedicular screw system fixation in thoracic vertebrae (T2-T7). 2) Anterior debridement, bone grafting and one-stage posterior transpedicular instrumental fixation in lumbosacral vertebrae (L5-S1). 3) Anterior focus elimination, bone grafting and one-stage anterior plate fixation in the other vertebrae. Results Forty-five patients were followed up for 24 to 40 months, with the average of 28.5 months. No severe complication occurred during and after operation. Forty-four cases had recovered and 1 recurred. Spinal fusion occurred 12-18 months after operation. Frankel neurological grades improved significantly. Conclusion With the effective management of comorbidities in perioperative period,the elderly could tolerate surgical treatment. The appropriate approaches, thorough debridement and reasonable bone grafting with internal fixation are key to therapeutic success.

ObjectiveTo investigate the mental state of the heroin addicts' closest relatives. Methods102 first degree relatives of 60 heroin addicts were measured using Symptom Checklist 90(SCL-90). ResultsThe SCL-90 score of somatization (1.73±0.60), depression(1.82±0.65), anxiety (1.80±0.55), mental disorder(1.56±0.49), paranoid(1.60±0.57) and count of positive items (41.41±18.87) were extremely higher than norm. ConclusionHeroin addicts'first degree relatives present some degree of somatization, depression, anxiety, mental disorder and paranoid.

Objective To approach the changes of serum insulin and peptide C and determine their relationship with inflammatory reaction in patients with severe multiple trauma. Methods The serum insulin, peptide C, tumor necrosis factor (TNF)-α, interleukin (IL)-10, C reactive protein (CRP) were detected in 30 patients with severe multiple trauma at days 1,3 and 7 after trauma to analyze the dynamic changes of serum insulin and peptide C and their correlations with Acute Physiology and Chronic Health Evaluation Ⅲ ( APACHE Ⅲ), cytokines and CRP. The changes of cytokines and CRP were also compared with those of serum insulin and peptide C in patients with different outcomes. The changes of serum insulin and peptide C of 35 healthy subjects were detected and used as control. Re-sults The serum insulin and peptide C levels of patients were higher than those in control group at each time point after trauma, with remarkably positive correlation with APACHE Ⅲ. Whether the serum glu-cose and age were controlled or not,serum insulin and peptide C were positively correlated with IL-10 at each time point and with TNF-α and CRP at days 3 and 7. The levels of serum insulin, peptide C and IL-10 were decreased with time in both groups with different outcomes. Meanwhile, the levels of TNF-α and CRP were decreased in the survival groups but increased in the death groups. The levels of above indices in death group were significantly higher than survival groups at the same time point. Conclusions The increasing of serum insulin and peptide C is correlated with inflammatory reaction after severe multiple trauma. The dynamic changes of both indices can either reflect injury severity or be used as an effective index in dynamically monitoring anti-inflammatory degree of the organism.

Objective To study the value of focused abdominal sonography for trauma (FAST) used by emergency doctor in emergency department. Method It's a prospective,double-blinded and controlled study from June 2008 to October 2009. A total of 97 casualties with severe multiple trauma, 72 male and 25 female aged from 14 to 88 years old with average age of (41 ± 16) ,admitted to emergency department were enrolled, and the bedside focused abdominal sonography for trauma was performed by emergency doctor. It was diagnosed as positive if free fluid was detected in abdomen or pericardium. The severe injury scores (ISS) were from 14 to 38 with average score of (23.2±9.3). The criteria of inclusion were age over 14 years old, injury happened within 12 hours and casualties admitted directly into emergency room. The criteria of exclusion were death of patients within 2 days without CT scanning of abdomen and exploration of abdomen with laporotomy, and operations directly determined by using FAST without conventinal sonographic examination. The FAST was compared with CT and conventional sonography judged by the findings observed during operation. Results The examination with FAST was completed in (3.18±0.79) min, whereas that with conventional sonography was (16.63t4.62) min(t = 28.61,P ＜0.001). The FAST was positive in 11 cases and negative in 86 cases, whereas the conventional sonography was positive in 13 cases and negative in 84 cases ( P = 0.5). There were 4 false negative findings in FAST resulting in 73% sensitivity, 100% specificity, 95.3% negative predictive value, 4.6% false negative rate, 100% positive predictive value, 0% false positive rate and 95.9% accuracy. Conclusions The emergency doctors are able to operate the FAST well for casualties with multiple trauma in emergency department after proper training.

Objective To investigate the efficacy of combined monitoring of motor evoked potentials with transcranial electrical stimulation (TES-MEP),somatosensory evoked potentials (SEP) and spontaneous electromyo-graphy (s-EMG) in tuberculosis surgery involving the thoracic,lumbar and sacral vertebrae.Methods Twenty-seven patients with tuberculosis of the thoracic vertebrae (T2-L2) received intra-operative SEP and TES-MEP monito-ring.Combined SEP,TES-MEP and spontaneous EMG monitoring were employed in 11 patients with tuberculosis of the lumbar or/and sacral vertebrae (L3-S1).SEP and TES-MEP were used to precisely observe the status of the sen-sory and motor pathways; s-EMG responses were used to more accurately localize nerve root irritation.ResuIts (1) SEP monitoring was successful in all of the operations.TES-MEPs were successfully monitored in 35 of them (92.1％).Combined motor and sensory monitoring was successfully achieved in 35 cases (92.1％).Abnormal SEPs were observed in 3 cases (7.9％),while abnormal MEPs were observed in 11 cases (28.9％).Abnormality in both the SEP and TES-MEP occurred in 2 cases (5.3％).There were 9 cases (23.7％) where the SEPs were nor-mal and the TES-MEPs were abnormal.In only 1 case (2.6％) was the SEP normal and the MEP abnormal.The false negative rate was 0％ with combined SEP and TES-MEP monitoring,while the false positive rate was 5.3％.There were 2 cases complicated by post-operative neurological deficits.(2) Spontaneous EMG monitoring can accu-rately determine the functioning of lumbar nerve roots during lumbar or lumbosacral tuberculosis surgery.Among 5 cases where EMG responses were observed,4 cases occurred during the spinal canal and nerve root decompression,1 case occurred in the orthopedic reset phase.Conclusions (1) During tuberculosis surgery involving thoracic,lumbar or sacral vertebrae,combined monitoring of SEPs and TES-MEPs can reflect the physiological and pathological condition of the spinal cord after ruling out interfering factors.This can improve monitoring and help assure the safety of lumbar surgery.(2) Intra-operative s-EMG monitoring can accurately reveal nerve root function in real time,help-ing to avert nerve root injury in lumbar and lumbosacral tuberculosis surgery.

Objective:To analyze the clinical and physical tactors associated with acute bone marrow suppression in concurrent chemo-radiotherapy for rectal cancer and to provide a reference standard for the best clinical treatment plan. Methods:Retrospective analy-sis was performed on 62 patients with rectal cancer who received concurrent radiotherapy and chemotherapy in our department. The pelvis was contoured for each patient in the radiotherapy treatment planning system and divided into three subsites: lumbosacral spine, ilium, and lower pelvis. Prognostic clinical and physical factors were analyzed by univariate and multivariate analyses. Evaluated prognostic clinical factors included sex, age, clinical stage, original hemoglobin levels, and chemotherapy, operation, and radiation modes;physical factors included V5, V10, V15, V20, V25, V30, V35, V40, V45, V50, Dmax, and Dmean of lumbosacral spine, ilium, low-er pelvis, and pelvis. Results:The percentage of patients who developed acute bone marrow suppression (≥2 grade) was 61.3%(38/62).Univariate analysis of related factors revealed statistically significant differences were sex, chemotherapy, lumbosacral spine V45, il-ium V20, and ilium V30. Multivariate logistic regression analysis indicated that chemotherapy and ilium V30 are the risk factors for acute bone marrow suppression. The receiver operating curve showed that the threshold of ilium V30 was 44%. Conclusion:Acute bone marrow suppression is influenced by more than one factor;local control rate of the tumor and acute bone marrow suppression are tradeoffs in rectal cancer treatment. An appropriate chemotherapy method should be selected, and ilium V30 must be maintained below 44%to prevent bone marrow suppression in rectal cancer patients.

ObjectiveTo observe the effect of light therapy combined with fluoxetine on winter attack depression.Methods68 patients of winter attack depression were divided randomly into the treatment group and control group with 34 cases in each group. Patients of the treatment group were treated by bright white light combined with fluoxetine (20 mg/d), but cases of the control group were treated only with fluoxetine. Therapeutic effects of two groups were evaluated with BDI, HAMD, and SCL-90 scales and traditional evaluation.ResultsPatients of the treatment group had a better effect than that of the control group (P<0.05).ConclusionLight therapy combined with fluoxetine has a good short and long term effect on winter attack depression, and can prevent from recurrence.

Objective Collecting the loosening periprosthetic interface-membrane, to discuss the mechanism of hip arthroplasty loosening. Methods The periprosthetic interface tissues of 29 hip arthroplasty revision cases from February 1995 to December 2003 were collected. The retrieved periprosthetic interface tissues were detected by immunohistochemistry. Some of them were studied by electronic microscope. Results (1)Transmission electronic microscope examination: the mitochondria swell. There were some substantia like lipid in the plasm of macrophages. Wear particles could be seen under scaning electronic microscope.(2)Immunohistochemistry: there were 22 IL-1? positive cases in cells of interface membrane. There were 29 IL-6 positive cases in cells of interface membrane. There were no positive results in TNF-? test. Conclusion (1)The wear particles of arthroplasty are important factors which cause biological reaction.(2)The interface membranes contain cytokine IL-1? and IL-6, which may play an important role in periprosthetic osteolysis and arthroplasty loosening.
