Objective To detect the expression of type Ⅰ collagen, type Ⅲ collagen, prolyl-4-hydroxylases (PH4) and matrix metalloproteinase 1 (MMP-1) in sacral ligament fibroblasts under stress, to understand the collagen synthesis and metabolism in stress situations change. Methods Eight patients who underwent abdominal hysterectomy for uterine benign disease were enrolled in this study. Primary sacral ligament fibroblasts were isolated by explant. After mechanical loading, gene expression of type Ⅰ , Ⅲ collagen, PH4 and MMP-1 were measured. Results Stress of 8% continuing for 24 hours, collagen Ⅰ (1. 13 ± 0.24), collagen Ⅲ (1.05 ± 0. 31) mRNA expression and PH4 expression (1.11 ± 0. 31) compared with static groups (1) showed increasing trends;when the stress were 4% and 12%, collagen Ⅰ (0. 86 ± 0. 26 and 0. 85 ± 0. 25), collagen Ⅲ showed increasing trends (0. 74 ± 0. 29 and 0. 83 ± 0. 38) mRNA expression were decreased. After removal of the stress, in the stress of 4% for 1 hour, collagen Ⅰ (0.79±0.40, 0.97±0.24 and 1.46 ±0.75), collagen Ⅲ (0.86±0.40, 0.99±0.60 and 1.59±0.82) and PH4 (1.11 ±0. 51, 1.17 ±0. 54 and 1.37 ±0. 39) mRNA expression increased gradually. In 8% stress group, collagen Ⅰ mRNA expression (1.16 ± 0. 62, 1.01 ± 0. 51 and 1.05 ± 0. 80) reached the peak in day 1, and collagen Ⅲ (0.99 ±0.69, 1.59 ±0.55 and 1.03 ±0.91) and PH4 (1.05 ±0.31, 1.07 ±0. 80 and 0. 85 ±0. 31) mRNA expression reached the peak in day 2, then decreased. 4% and 8% of the stress with time after the change, MMP-1 mRNA expression have peaked at day 1. Conclusions Moderate stress could contribute to pelvic floor collagen synthesis, too much or too little stress is not conducive to the synthesis of collagen. Collagen Ⅰ and collagen Ⅲ on the stress response may be different, the former have faster reaction than the latter. PH4 were involved in the synthesis of collagen, while MMP-1 may play a role in collagen degradation.

Objective To analyze the sensitivity and specificity of several volume parameters regarding volume responsiveness.The studied volume parameters include pulmonary artery obstruc-tion pressure (PAOP),central venous pressure (CVP),right ventricular end-diastolic volume (RV-EDV)measured by Swan-Ganz pulmonary artery catheter and left ventricular end-diastolic area (LVEDA),inferior vena cava diameter (IVC)measured by transesophageal echocardiography (TEE). Methods Twelve patients with ASA Ⅱ or Ⅲ,scheduled for coronary artery bypass grafting were studied.After anesthesia induction,the TEE probe was put into the esophagus and Swan-Ganz cathe-ter was placed in right internal jugular venous.Measurements were made at the time before cutting the skin (T0 ),20 min after divorcing from cardiopulmonary bypass or finishing vascular anastomosis in off-pump surgery(T1 ),10 min after rapid infusion (T2 )and 30 min after rapid infusion (T3 ),re-spectively.Results The values of PAOP,IVC,LVEDA,COLVOT at time T2 increased significantly compared to those at time T1 (P <0.01).No obvious correlation (r=-0.298 5、r=-0.091 8、r=-0.243 6)was observed between △CVP、△PAOP、△RVEDV and △COLVOT (the difference between T2 and T1 );Meanwhile,△IVC and △LVEDA were well correlated to △COLVOT (r= 0.445 0、r=0.612 0).Using more than 1 5% change of COLVOT after volume expansion as definition of positive re-sponse,the areas under the receiver operating characteristic curves of CVP,PAOP,RVEDV,IVC and LVEDA were 0.389 (95% CI 0.035-0.743 ),0.458 (95% CI 0.109-0.807 ),0.333 (95% CI 0-0.671 ), 0.903 (95% CI 0.701-1.000 ) and 0.889 (95% CI 0.661-1.000 ), respectively. Conclusion PAOP,IVC,LVEDA,CO are more sensitive to the change of volume;while CVP and RVEDV have weak responses to volume changes.This indicates that IVC and RVEDA have more ad-vantage to estimate cardiac output increase and guide volume therapy.

Objective To investigate clinical value of pubococcygeal line (PCL) determined by dynamic magnetic resonance imaging (MRI) used in evaluating pelvic organ prolapse (POP), and investigate the relationship of pelvic organ prolapse quantitation (POP-Q) stage and pubococcygeal line (PCL) for the patient with POP. Methods Twenty patients with POP were evaluated by POP-Q stage and pelvic dynamic MRI examination simultaneously. Sagittal MRI images were acquired at rest and during maximal Valsalva using a fast gradient echo sequence two-dimensional fast low angle shot (FLASH) T1weighted image. The degree of prolapsed anterior vaginal wall, uterus and posterior vaginal wall were measured by PCL and compared with POP-Q system. Results There were 20 cases with cystocel diagnosed by POP-Q staging system, in which bladder neck or bladder base of 17 patients were under the PCL during maximum Valsalva. The concordance rate was 85% (17/20) between PCL and POP-Q stage. There were 19cases with rectocele diagnosed by POP-Q, in which the anorectal junction of 4 patients' PCL descent below more than 2. 5 cm. The concordance rate was 4/19 between PCL and POP-Q stage. There were 14 cases with uterine prolapse diagnosed by POP-Q staging system, in which uterine cervix of all descent below PCL. The concordance rate was 14/14 between PCL and POP-Q stage. However, it was noted that 5 cases did not reach POP-Q staging and their lowest uteri cervix were below or above PCL but less than 1 cm at maximal Valsalva. Conclusions Compared with POP-Q staging system, the reference line of PCL determined by dynamic MRI could diagnose uterine prolapse accurately and anterior vaginal wall with greater clinical value,however it was limited in diagnosing posterior vaginal wall prolapse effectively. Therefore, the clinical value of PCL should be further studied for evaluating POP.
