The levels of adrenocorticotropic hormone (ACTH), 17-hydroxyprogesterone(17-OHP), androstenedione(AD), total testosterone(TT), and progesterone were higher in women with NC21-OHD compared with those with PCOS(P<0.05). Women with PCOS had higher levels of luteinizing hormone(LH) and higher ratio of LH to follicle stimulating hormone(FSH) than those with NC21-OHD(P<0.05). The best two identification indexes for the two diseases were 17-OHP and progesterone, with the optimal cut-off points 3.34 ng/ml(sensitivity 89.7%, specificity 93.1%) and 0.64 ng/ml(sensitivity 90.0%, specificity 75.9%), respectively. During the 1-day mid-dose dexamethasone suppression test(DST), women with NC21-OHD had higher inhibition rates of 17-OHP, progesterone, AD, and TT(P<0.01) than those with PCOS. Their optimal cut-off values of suppression rates were 73.5%(sensitivity 95.2%, specificity 100.0%), 55.5%(sensitivity 100%, specificity 88.9%), 61.4%(sensitivity 84.2%, specificity 100.0%), 68.3%(sensitivity 65.0%, specificity 100.0%), respectively. \u0000 \u0000 \u0000Conclusion \u0000The clinical manifestations of women with NC21-OHD are similar to those with PCOS. 17-OHP is the best differential indicator and the 1-day mid-dose DST plays an important role in the identification of the two diseases.

Previous studies have indicated that, compared with type 2 diabetes in Caucasian, type 2 diabetes in East Asians is characterized primarily by β cell dysfunction rather than insulin resistance. This pathophysiological characterization of diabetes in East Asians is mainly derived from Japanese and Asian-American populations, whereas data from mainland China are scarce. Over the past four decades, China has witnessed a substantial rise in obesity, in parallel with the transitions from principally active lifestyles and calorie-restricted diets to sedentary life styles and energy-dense, western diets. Obesity is an insulin resistance state and the major factor driving the worldwide epidemic of diabetes. It is unknown whether, and if so how, obesity affects the two primary mechanisms, insulin resistance and β cell dysfunction, responsible for the development of diabetes in the Chinese population.
