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 observe the characteristics of gene expression of type X collagen in the cartilage of end-plate and the fibrous annulus in the intervertebral disc of idiopathic scoliosis (IS) patients.

METHODInvestigating the expression of type X collagen in the peak disc and the lower end disc of 21 IS patients, the peak disc of 16 congenital scoliosis (CS) and the lumbar disc of 3 normal people (according with the principle of medical ethnics) by reverse transcript polymerase chain reaction.

RESULTSThe expression of type X collagen in the concave side of IS peak disc was higher than the convex side (P < 0.05). There was no significant difference of gene expression of type X collagen between the convex side and the concave side of the lower end disc (P > 0.05). The gene expression of type X collagen in the IS peak disc was higher than those of lower end disc (P < 0.05). For the CS peak discs, the expression of type X collagen of the concave side was higher than the convex side (P < 0.05).

CONCLUSIONThe expression of type X collagen of the IS peak disc increases, and the expression of type X collagen of the concave side is higher than the convex side. These changes may be secondary.

OBJECTIVETo observe early clinical efficacy of general spine system (GSS) in spondylolisthesis combined with lumbar canal stenosis, lumbar decompression, reduction and bone graft.

METHODSSixteen patients with degenerative lumbar spondylolisthesis combined with lumbar canal stenosis, 10 male, 6 female, average age 58.5 years (range 42 - 72 years) underwent lumbar decompression, bone graft and internal fixation using GSS. Preoperatively 10 patients had degree I spondylolisthesis and 6 patients had degree II spondylolisthesis. Clinical efficacy, reduction effectiveness and complications were recorded.

RESULTSThe 16 patients in this group were followed up postoperatively for an average of 21.2 months (18 - 24 months). At latest follow-up after surgery, preoperative clinical symptoms had disappeared completely in 15 of 16 patients, and low back pain relief was seen in 15 patients. Average duration of surgery was 170 min (120 - 270 min), and average blood loss was 375 ml (100 - 800 ml). X-ray results showed complete reduction for all spondylolisthesis patients, and results remained good in follow-up. Dura mater tearing, pedical fracture, nerve injury and other surgical complication did not occur. Screw breakage, screw loosening and instrument loosening at the screw-rod juncture were not observed after surgery or in follow-up.

CONCLUSIONGSS provides good reduction for spondylolisthesis, and shows good early clinical efficacy.
