Objective To investigate the reliability of the Three-Column classification for fracture of tibial plateau and compared with the conventional Schatzker classification.Methods From December 2004 to March 2007,304 patients with tibial plateau fracture were treated in our department.The CT scans and 3D reconstruction were performed in all patients before operation.All the patients were classified by the Three-Column classification and then treated with open reduction and internal fixation via the corresponding approaches based on the Three-Column classification.To validate the Three-Column classification,four doctors classified 50 patients which were chosen randomly from 323 consecutive fracture cases.Schatzker classification was also classified at the same time.Inter-observer reliabilities of the Three-Column classification and the Schatzker classification were figured out respectively in the form of Kappa value.Results According to the Three-Column classification,there were 4 pure compression fractures (1.2％),181 one-column fractures(56.0％),108 two-column fractures(33.4％) and 30 three-column fractures (9.3％) in all 323 cases.In one-column fracture cases,the numbers of lateral,medial,and posterior column fractures were 114 (63.0％),53 (29.3％),and 14 (7.7％),respectively.Among two-column fracture cases,the lateral-medial column fractures (33.3％) were 36.While the number of medial-posterior column fractures and lateral-posterior column fractures were 34 (31.5％) and 38 (35.2％),respectively.There was a moderate inter-observer reliability when using Schatzker classification (Kappa=0.567; range,0.513-0.589).There was a substantial interobserver reliability when using the Three-Column classification (Kappa=0.766; range,0.706-0.890).Conclusion The Three-Column classification based on CT and 3D reconstruction is simple and more reliable for fracture of tibial plateau.It is suggested that the new classification system,the Three-Column classification,can be used and popularized in the orthopaedic surgery.

Objective To investigate the clinical and genetic characteristics in a patient with 17β-hydroxy-steroid dehydrogenase (17β-HSD) 3 deficiency, regarding its pathophysiology and pathogenesis. Methods Clinical features and laboratory data were analyzed in a pedigree of 17β-HSD3 deficiency. Blood samples from the patient and his parents were collected. HSD17B3 gene was screened for mutations by PCR and subclone sequencing. Results The patient presented with pubertal virilization and gynecomastia. The physical examination showed female external genitalia and testes in inguinal canals. The chromosome karyotype was 46, XY. Serum FSH, LH, dehydroepiandrosterone sulfate, androstenedione and 17-OH-progesterone levels were raised, whereas plasma testosterone was lowered. Sequencing analysis revealed 4 nucleotide deletion (172-175del) of HSD17B3 gene. Conclusion Virilization and gynecomastia in puberty suggest the probability of 17β-HSD deficiency. It may be verified clinically by hCG-stimulating test and confirmed by gene diagnosis.

Objective To explore the potential mechanism of adrenal androgen excess in patients with polycystic ovary syndrome (PCOS), ACTH stimulation test was conducted and the polymorphisms in the promoter region of CYP21 A2 gene were screened to verify the variations related to the responsiveness to ACTH stimulation. Methods 30 healthy women and 101 PCOS patients, matched for age, were recruited from Ruijin hospital. Blood biochemical examinations were taken and sex hormone profiles obtained at baseline. 17 hydroxyprogesterone( 17OHP)was measured at 0 and 60 min in an ACTH stimulation test. The -710 bp -1 bp of the promoter region of CYP21A2 was sequenced in 87 PCOS patients and 30 control subjects. Results According to the post-stimulation 17 OHP levels obtained from 30 healthy women,PCOS patients were allocated into one group with high responsiveness to ACTH ( HR-PCOS, n = 21) and the other with normal responsiveness to ACTH ( NR-PCOS, n = 80). Compared with NR-PCOS subjects, HR-PCOS patients had higher testosterone( P<0.05), basal and post-stimulation 17OHP (both P<0.01)and dehydroepiandrosterone sulfate levels (P<0.05 or P<0.01) .whereas serum cortisol and androstenedione levels were not significantly different before and after ACTH stimulation test. The genotypes of locus -535 were well correlated with post-stimulation 17OHP levels (r = 0. 20,P = 0. 03) in PCOS patients and the control subjects. The genotype T/T or allele T was significantly more frequent in subjects with a higher fertile of post-stimulation 17OHP (P<0.05 or P<0. 01). The odds ratio(OR)for higher responsiveness to ACTH in women with allele T at -535 was 3. 69 (95% CI 1. 69-8. 06,P = 0. 000 7). Conclusions The PCOS patients with higher responsiveness to ACTH are characterized by severe hyperandrogenemia and adrenal androgenexcess,suggesting that adrenal androgen excess in some PCOS patients may be due to higher responsiveness to ACTH. The polymorphism of -535C>T in the promoter region of CYP21 A2 may play a role in regulating 21 hydroxylase gene expression and further influencing 17OHP responsiveness to ACTH.
