Serum visfatin and macrophage migration inhibitory factor levels in pregnant women withobstructive sleep apnea hypopnea syndrome / 中华全科医师杂志

One hundred and two pregnant women with obstructive sleep apnea hypopnea syndrome (OSAHS) and 36 healthy pregnant women( control group)were enrolled in the study.Serum visfatin and macrophage migration inhibitory factor (MIF) levels were detected by enzyme linked immunosorbent assay (ELISA).The results showed that apnea-hypopnea index (AHI),mean arterial pressure(MAP),serum visfatin and MIF levels in pregnant women with OSAHS were significantly higher than those of controls ( all P＜ 0.01 ). In pregnant women,AHI,serum visfatin and MIF levels of patients having OSAHS with hypertension were significantly higher than those of patients with OSAHS only (all P ＜ 0.01 ).Patients with severe OSAHS had higher levels of visfatin and MIF than those with moderate OSAHS,and patients with moderate OSAHS had higher visfatin and MIF levels than those with mild OSAHS ( P ＜0.01 ).The AHI was significantly correlated with MAP,serum levels of MIF and visfatin ( r =0.75,0.71,0.68,respectively,all P ＜0.01 ) in pregnant women with OSAHS.

Increased levels of prostaglandin high mobility group box-1 and high-sensitive C-reactive protein in peritoneal fluid and serum of patients with endometriosis / 中华全科医师杂志

The concentrations of prostaglandin in high mobility group box-1 ( HMGB1 ) and highsensitive C-reactive protein (Hs-CRP) in serum and peritoneal fluid were detected in 76 patients with endometriosis (study group) and 30 patients without endometriosis (ovary cysts or uterine myoma, as control group). The peritoneal fluids were collected during laparoscopic operation, and the serum samples were collected before surgery. The HMGB1 and Hs-CRP concentrations in serum and peritoneal fluid of study group were significantly higher than those of control group, ( 8. 2 ± 0. 8) mg/L vs. (2. 1 ±. 0. 2) mg/L、 ( 14. 4 ±3.0) mg/L vs. (4.5 ±2.3) mg/L (both P＜0. 01);HMGB1 and Hs-CRP levels in serum and peritoneal fluid of stage Ⅲ-Ⅳ endometriosis were significantly higher than those of stage Ⅰ-Ⅱ, ( 9. 2 ± 0. 8) mg/L vs.(6.7 ±0.7) mg/L,(18.7 ±2.9) mg/L vs. (11.2 ±2. 8) mg/L,(6.5 ±0.6) mg/L vs. (3.4 ±0.5) mg/L,(8.4 ±2.7) mg/L vs. (5.4 ±2.4) mg/L (all P ＜0.05). The concentrations of HMGB1 were positively correlated with Hs-CRP in endometriosis group (r =0. 72, P ＜0. 01 ). The results indicate that concentrations of HMGB1 and Hs-CRP may be of value in assessing the severity of endometrosis.

The relationships between serum interleukin-18 and resistin for predicting intraamniotic infection / 中国医师进修杂志

Objective To study the relationships between serum intedeukin-18(IL-18)and resistin for predicting intraamniotic infection.Method Serum levels of IL-18 and resistin were measured in 43 pregnant women with intraamniotic infection (infection group)and 40 normal pregnant women(control group).Results The level of IL-18 in infection group[(38.7±10.4)μg/L]was higher than that in control group [(23.5±5.6)μg/L],there was significant difference between two groups (P＜0.01).The level of resistin in infection group[(24.84±5.32)μg/L]was higher than that in control group[(17.3±5.15) μg/L],there was significant difference between two groups(P＜0.01).The levels of resistin and IL-18 were correlated in pregnant women with intraamniotic infection(r=0.61,P＜0.01).Conclusion Detecting the levels of IL-18 and resistin in pregnant women can identify intramnniotic infection.

Determination of serum levels of visfatin and high-sensitivity C-reactive protein in patients with polycystic ovary syndrome / 中华全科医师杂志

Objective To explore serum levels of visfatin and high-sensitivity C-reactive protein (Hs-CRP) in patients with polycystic ovary syndrome (PCOS), as well as their clinical significance. Methods Ninety patients with PCOS and 30 ovulating healthy women with body mass index (BMI) less than 25 as controls were recruited. PCOS patients were divided to two groups, 48 in obese group with BMI≥ 25 and 42 in non-obese group with BMI<25. Serum level of visfatin was measured by enzyme-linked immunosorbent assay (ELISA) and that of Hs-CRP was assayed by immunoturbidimetry in all participants. Oral glucose tolerance test (OGTT) and insulin sensitivity were assessed in PCOS patients only. Results ①Obese and non-obese patients with PCOS beth presented markedly higher serum levels of visfatin and Hs-CRP than those in controls (t=11.35, 8.46, 10.43 and 8.25, respectively, P<0.05), and levels of visfatin and Hs-CRP were higher in obese group than those in non-obese group (t=7.74 and 6.38, respectively, P< 0.05 ). ②Univariate analysis revealed that serum levels of visfatin and Hs-CRP positively correlated with BMI and homeostasis model assessment insulin resistance, respectively (P<0.05) and serum level of visfatin positively correlated with that of Hs-CRP (P<0.05). Conclusions Chronic inflammation possibly exists in patients with PCOS, which may cause their serum visfatin and Hs-CRP levels increased.
