Objective To evaluate cerebrospinal fluid adenosine deaminase(CSF-ADA)activity in the diagnosis of tuberculous meningitis(TMB), and to observe its dynamic changes. Methods A total of 160 patients were included and were divided into two groups: 76 cases of TBM and 84 cases of non-TBM.Among the cases of non-TBM, there were 36 cases of bacterial meningitis, 30 cases of viral meningitis and 18 cases of cryptocoocal meningitis. All the patients were measured with their CSF-ADA activity by Enzymecoupled assay(Trinder method)and 47 patients of TBM were measured again after 2 weeks' and 6 weeks'antitubercular therapy. Results were expressed as(-x)± s. Mann-Whitney U test and paired-samples t test were used. Results CSF-ADA activity in TBM group was(12.9 ±6.4)U/L, while that in the non-TBM group was(6.0 ± 4.1)U/L, the difference was of statistical significance(U = 7.860, P < 0.05). With the cutoff value of 9 U/L, the sensitivity and specificity to differentiate TBM from non-TBM was 84.21% and 83. 33%, respectively. CSF-ADA activity decreased in TBM patients after antitubercular treatment.Conclusions CSF-ADA activity can be an effective laboratory marker for early differential diagnosis of TMB with the cut-off value of 9 U/L. Dynamic changes of CSF-ADA activity may be a indicator for the effect of antitubercular treatment.

Objective To evaluate two kinds of anterior screw fixations in the treatment of odontoid fractures. Methods A total of 36 patients with D' Alonzo type Ⅱ odontoid process fractures were treated with anterior screw fixation in our department from 1999 to July 2009. There were 28 males and 8 females at mean age of 42.3 years (rang 17-59 years). According to time and surgery procedures, the patients were divided into Group A ( from 1999 to June 2005, n = 11 ) and Group B ( from June 2005 to July 2009, n = 25 ). Patients in Group A received anterior hollow screw fixation of the odontoid process monitored under G-arm or C-arm, while those in Group B received anterior screw fixation of the odontoid process assisted by Iso-C 3D navigation system. The operation time and blood loss in two groups were compared by Student' s t test and analyzed with SPSS 13.0 statistical software. X-ray examination was performed in all patients 3, 6 and 12 months after operation to observe fracture union and stability of the upper cervical spine. Results The operation time was ( 102 ± 12) min ( range, 77-148 min) in Group A and ( 104 ± 14) min ( range, 71-150 min) in Group B, with no statistical difference ( P =0.21 ). The blood loss was (465 ± 5) ml (range, 20-130 ml) in Group A and (42 ± 6) ml (range, 26-150 ml) inGroup B, with no statistical difference (P = 0.16). All patients received reexamination three months after operation, which showed no bony union or dislocation but average 40% restriction of neck rotation. One year after operation, 30 patients (83%) got fracture union and six ( 17% ) got fiber healing, with average 24% restriction of neck rotation. Conclusions There is no statistical significant differences between two groups in aspects of operation time, blood loss and fracture healing. But anterior screw fixation of the odontoid process assisted by Iso-C 3D navigation system can reduce exposure to radiation of both patients and surgeons. Furthermore, solid screws can be applied to augment the fixation intensity and thereby reduce the complications caused by non - union.

OBJECTIVETo compare anatomical differences between subinguinal and ilioinguinal approaches for the treatment of acetabular fracture and investigate clinical therapeutic effect of subinguinal approach.
METHODSSeven fresh human bodies were chosen, comparative study were performed on the right and left side on the same specimen. Ilioinguinal approaches were adopted on the left and subinguinal were adopted on the right. Inner part of incision started to sun wild above pubic symphysis at 2 cm, and lateral incision ranged from iliac to anterior superior spine about 5 cm. Length and transverse diameter of the first window exposed and lliopsoas freeness were tested and compared. Fifteen acetabular fracture patients treated through subinguinal approach were compared from May 2010 to August 2012. Among all patients, including 12 males and 3 females aged from 20 to 65 years old with an average of 40.6 years old. Matta criteria were used to evaluate clinical outcomes.
RESULTSLength and transverse diameter of the first window exposed and lliopsoas freeness through subinguinal approach were better than through ilioinguinal approach (P<0.01). In 15 patients with acetabular fracture, 10 patients obtained anatomical reduction and 10 patients got satisfied reduction in accordance with Matta criteria. X-ray results of all patients were excellent.
CONCLUSIONCompared with ilioinguinal approach, subinguinal approach could enlarge visualization of the first window and simplify surgical procedure. It is an ideal approach to expose anterior and anterior-medialis wall of acetabulum and anterior hip capsule.

Objective To study the clinical outcome of percutaneous vertebroplasty (PVP) for the s disease who had been suffering severe back pain even after conservative therapy for months were treated with PVP. Their preoperative CT images indicated nonunion of factures and "vacuum signs". Dynamic X-ray films demonstrated formation of pseudoarthrosis in the involved vertebral bodies in some eases. Their back pain was evaluated with visual analogue scale (VAS). Their preoperative and postoperative VAS scores and radiological indexes were compared. Results The mean VAS scores were 7.0±1.2 preoperatively, but 3.1±1.5 at the follow-up (P < 0.05) . The height of anterior margin of involved vertebral body was (2.1±0.3) cm pre-operatively, but (2.3±0.2) cm at the follow-up (P < 0.05). The ratio of anterior margin height to posterior margin height of the involved vertebral body was 0. 67±0. 10, but 0.84±0.08 at the follow-up (P<0.05), The focal kyphosis angle was 27.3°± 6.4° preoperatively but 20.7°±5.0° at the follow-up (P < 0.05). No pulmonary embolisms or neurological injuries happened. Conclusion PVP is an effective method for anterior margin of the involved vertebral body partially, and decrease the focal kyphosis.

In order to investigate the prevalence and track genetic and antigenic evolutions of infectious bronchitis virus (IBV) and their prevalence in Guangxi, China since 1985, gene amplification and sequencing and virus neutralization (VN) test on chicken embryo tracheal organ cultures were used in genotyping and serotyping of 28 IBV isolates during 2009-2011 in Guangxi. The results of N gene sequencing and comparison showed that the 28 isolates and reference strains were classified into three groups, and most isolates belonged to group Ill, while the isolates in 1985-2008 belonged to groups IV and II. The data of VN test indicated that the 28 isolates belonged to 6 serotypes; among them, 71. 4% belonged to serotypes 1, 2, and 3, and 11 (39.3%) shared the same serotype with the current vaccine strains. Given the data of our previous study, it is found that prevalent serotypes and their proportions varied in different areas of Guangxi and during different periods. These data lay a good foundation for developing an oil-emulsified inactivated polyvalent vaccine containing local dominant serotypes for the effective prevention and control of infectious bronchitis.

OBJECTIVESTo study the characteristics of senile patients during perioperative lumbar operation and discuss matched surgical method.
METHODSFrom 1998 to 2000, lumbar operations were performed in 41 elderly patients (average age 68). 14 patients had lumbar disc herniation, 11 lumbar disc herniation with lumbar spinal stenosis, 12 lumbar instability and spondylolisthesis, 2 reoperation, and 2 combined compression of cervicle and thoracic spinal cord.
RESULTSMany patients were complicated by the following diseases: hypertension (14), coronary heart disease (9), diabetes mellitus (4), cerebral infarction (3), rheumatic heart disease (1), pulmonary heart disease (1), and complicated with 2 or 3 diseases (9). Discectomy was performed in 14 patients, decompression + discectomy in 11, posterior lateral fusion with pedicle instrument in 9, posterior lateral intravertebrae fusion with instrument in 3. Fixation of 2 levels was made in 5 patients, 3 levels in 3, and multi-levels in 2. Postoperation JOA amelioration rate was 81.6%.
CONCLUSIONThe condition of adjacent segment should be considered in the operative treatment of elderly patients. Caution should also be taken to coexisting diseases.
