OBJECTIVETo investigate the association of erectile dysfunction (ED) with metabolic syndrome ( MS) and the total testosterone ( tT) level in young and middle-aged men.

METHODSThis study included 154 organic ED outpatients aged 20 -59 years and 103 age-matched men with normal sexual life. We obtained their waist circumference ( WC) , blood pressure ( BP) , fasting blood glucose ( FBG) , triglyceride ( TG) , high density lipoprotein ( HDL) , tT, IIEF -5 score, erectile function indexes and other relevant variables, and compared them between the ED and non-ED groups as well as between the ED patients with MS and those without MS.

RESULTSThe prevalence of MS was significantly higher in the ED patients than in the non-ED males ( 40. 9 vs 17.4%, P < 0. 01). Statistically significant differences were found between the ED and non-ED groups in WC ( [90. 80 ±4. 90] vs [87. 70 ±4. 60] em, P <0.01), SBP ([134.40±14.40] vs [129.90±12.40] mmHg, P

CONCLUSIONThe prevalence of MS is significantly higher in young and middle-aged ED patients than in normal males, and MS is associated with a lower testosterone level and poorer erectile performance. Central obesity is closely correlated with ED in young and middle-aged men.

Objective To study the clinical significance of bone reconstruction at cranial base for severe traumatic comminuted fractures of anterior skull base. Methods Forty-six bone defect cases were divided into treatment group and control group randomly. Treatment group was treated with the bone reconstruction therapy, while the control group was not. All the patients received the follow-up ranging 6 months to 1 year, and examined with CT and/or MRI to observe leakage of cerebrospinal fluid,intracranial infection and encephalomeningocele. Results In the treatment group, one of the 18 survivals developed mild cerebrospinal fluid leakage, which was cured later. In the control group, 5 of the 17 survivals had cerebrospinal fluid leakage, 3 had intracranial infection and 3 encephalomeningocele.The total incidence of complications of the treatment and control groups was 1/18 and 5/17, respectively,and the former was significantly lower than the latter (P＜0.05). Conclusions Bone reconstruction can avoid intracranial infection, cerebrospinal fluid leakage and encephalomeningocele during the operation for traumatic comminuted fractures of anterior skull base.

OBJECTIVETo investigate the binding mechanisms of FVIII Trp1707Ser mutation-associated inhibitor.

METHODSThe APPT, PT, TT, Fg and FVIII:C were detected to make phenotypic diagnosis of haemophilia A. Inhibitors titer were measured by Bethesda method. Long distance-PCR (LD-PCR) and sequence-specific PCR were adopted for screening the intron 22 and intron 1 inversions respectively. FVIII coding and boundary sequences were analyzed by direct DNA sequencing. Inhibitor was reacted with different segments of FVIII, including heavy chain and its components A1 and A2, light chain and its components A3, C1 and C2. Corrected test was used to measure the remaining F VIII:C (% ) by adding pooled normal plasmas. After labeling purified inhibitors with biotin, western blot was performed to further confirm the binding reactions between inhibitors and segments.

RESULTSThe haemophilia A patient had mild deficiency of FVIII:C (1.1%) and had high FVIII inhibitor titer of 18.4 BU. A mutation c.97223C>G in exon 14 of F8 gene resulted to p.Trp1707Ser was identified by DNA sequencing. Corrected test showed that the remaining F VIII:C was increased when inhibitors reacted with heavy chain and light chain, especially with heavy chain. The remaining FVIII:C was also increased in the A2 and C2 domain reactions. No significant differences were seen in the A1, A3 and C1 domain reactions. Antigen-antibody reaction bands were confirmed by western blots when degenerated B-domain deleted recombinant FVIII, A2 and C2 were used as antigens.

CONCLUSIONThe binding sites of FVIIITrp1707Ser mutation inhibitor were the A2 domain of heavy chain and C2 domain of light chain. The binding reaction with heavy chain was more intense.

OBJECTIVETo analyze the causes of the complications associated with the pedicle screw fixation during and after operation, as well as the methods for prevention and treatment.

METHODSFrom January 1988 to December 1999, 475 patients who underwent pedicle screw fixation for various spinal disorders were reviewed retrospectively with statistical analysis.

RESULTSFour hundred and twenty-eight patients (90.1% of all) were followed up for (6.0 +/- 3.7) years. Complications of CD, DRFS, Dick, RF and steffee among 72 cases (80% of all) occurred during the operation of pedical screw fixation in 26 cases with the incidence of 5.5% and after the operation in 64 cases with the incidence of 15%. The incidence of operative/postoperative complications were 0-12.9% in CD, 6.8%-11.9% in DRFS, 7.3%-12.7% in Dick, 2.4%-19.5% in RF, and 10.1%-21.5% in Steffee respectively. The main complications included pseudoarthrosis, pedicle screw broken, pedicle screw malposition and so on. The complications were mainly due to unskilled technique of pedicle screw fixation, implant defect in design and so on.

CONCLUSIONSThe complications associated with the technique of pedicle screw fixation must not be neglected. The main causes are laid on unskilled technique of pedicle screw fixation and implant defect in design.

OBJECTIVETo investigate the mid-term radiological outcome of sagittal alignment of overall cervical spine and the functional spinal unit after replacement surgery with Bryan cervical disc prosthesis.

METHODSEighteen patients with cervical disc disorder were performed cervical disc replacement with 20 Bryan discs from November 2005 to May 2010, including single-level 16 cases and bi-level 2 cases. The patient consisted of 13 males and 5 females with age ranging from 38 to 59 years (average, (47 ± 6) years). Fourteen cases with overall cervical lordotic alignment and segmental lordotic alignment per-operatively (group 1) and 4 others with segmental kyphotic alignment and overall cervical kyphotic alignment per-operatively (group 2). The overall sagittal alignment (C(2-7)) and segmental sagittal alignment were measured pre-operatively, post-operatively and at final follow-up to evaluate the outcome.

RESULTSAll cases obtained the follow-up with an average of (24 ± 5) months (range 12 to 53 months). To the mean overall cervical alignment, there were 9.9° ± 1.9° per-operatively, 12.8° ± 2.1° post-operatively and 11.6° ± 1.8° at final follow-up in group 1 and -1.8° ± 0.8° per-operatively, 7.3° ± 1.3° post-operatively and 5.0° ± 2.1° at final follow-up in group 2. There were statistical significance between per-operatively and post-operatively (t = -2.987 and -5.058, P < 0.05) and no statistical significance between post-operatively and final follow-up (P > 0.05) in both groups. To the mean segmental alignment there were 2.6° ± 0.8° per-operatively, 5.4° ± 1.0° post-operatively and 4.3° ± 0.9° at final follow-up in group 1 and -3.0° ± 0.8° per-operatively, 3.8° ± 1.3° post-operatively and 0.3° ± 2.8° at final follow-up in group 2. There were statistical significance between per-operatively and post-operatively in both groups (t = -3.829 and -4.086, P < 0.05) and between post-operatively and final follow-up in group 1 (t = 2.630, P < 0.05)but not in group 2 (P > 0.05).

CONCLUSIONSThe Bryan cervical disc prosthesis has a good mid-term outcome for maintaining sagittal alignment of overall cervical spine and the functional spinal unit. Long-term follow-up should be needed to assess the long-term functionality of the prosthesis.

OBJECTIVETo compare and evaluate instrumented posterior fusion with instrumented circumferential lumbar fusion in the treatment of lumbar stenosis with low degree lumbar spondylolisthesis.

METHODSFrom April 1998 to April 2003, 45 patients who suffered from lumbar stenosis with low degree lumbar spondylolisthesis were divided into 2 groups (A and B) at random. The patients in group A (n = 24, average age 54 years old) were performed decompressive laminectomy, intertransverse process arthrodesis with bone grafting and transpedicle instrumentation of solid connection (SOCON) system. The patients in group B (n = 21, average age 53 years old) were performed the same procedure as group A except adding posterior lumbar interbody fusion (PROSPACE). The main levels of lumbar spondylolisthesis in 2 groups was L(4 - 5) or L(5)-S(1). All cases were classified as degree 1 to degree 2. All patients in the two groups received preoperative myelography or CTM, and were diagnosed lateral recess stenosis and(or) central lumbar canal stenosis.

RESULTSAll the patients were followed up from 12 to 72 months. In group A, the results showed that the preoperative clinical symptoms disappeared completely in 12 of 24 patients, pain relief was seen in 91.7% (22/24), anatomical reduction rate was 91.7%. No infection or neurologic complication occurred in this series. In group B, the results showed that the preoperative clinical symptoms disappeared completely in 13 of 21 patients, pain relief was seen in 90.5% (19/21), anatomical reduction rate was 95.2%. Four cases of infection or neurologic complication occurred in this series. Two groups had no significant difference in follow-up clinical outcome and anatomical reduction rate. But group A had better intraoperative circumstances and postoperative outcome than group B, group B had better postoperative parameters in X-ray of angle of slipping and disc index than group A.

CONCLUSIONSThe best surgical treatment method of lumbar stenosis with low degree lumbar spondylolisthesis is complete intraoperative decompressive laminectomy, reduction with excellent transpedicle system instrumentation and solid fusion after bone grafting. The use of cage should be conformed to strict indications.
