To explore the mode of"one-day outpatient"based continuous management and examine its feasibility and preliminary effects for improving menopausal syndrome and mood among menopausal women.Clinical intervention study was conducted in Obstetrics and Gynecology Center of the Third Affiliated Hospital of Chongqing Medical University from May 2020 to May 2021.The continuous management mode of "one-day outpatient service" for menopause was constructed in terms of multidisciplinary resources, including offline "one-day outpatient" health education, online 7-week group continuous intervention on "healthy lifestyle" and offline half-day focus group interview. Pre-and post-scores of the modified Kupperman scale and the positive/negative emotional scale (PANAS) were measured to compare the status of menopausal syndrome and emotional experience of Seventy-eight female participants (40-60 years old), meanwhile, before and after comparison of the blood lipid and body composition indexes of participants were also performed. Paired t test or Wilcoxon signed rank test were used.Results show that the pre-and post Kupperman scores were 14.65±8.51 vs 10.26±5.83 ( t=-5.59, P<0.01), and the positive emotional scores (pre- 28.53±5.85 vs post- 30.13±6.30) were improved ( t=2.59, P=0.012) and negative emotional scores [pre- 20.5(10) vs post- 17.0(7)] were decreased ( Z=-5.09, P<0.01). The triglyceride level of participants declined from (1.27±0.54) mmol/L to (1.09±0.38) mmol/L ( t=-2.45, P<0.05). In addition, the body mass index(pre- 22.52±2.34 vs post- 22.06±2.22), percentage of body fat (pre- 31.72±6.22 vs post- 30.91±6.52)and Visceral fat area(pre- 83.96±30.26 vs post- 79.66±29.71) were all improved ( t=-3.58, t=-2.57, t=-2.59, P<0.05). Therefore,the mode of"one-day outpatient"based continuous management can effectively improve menopausal syndrome and adverse mood, reduce patients′ blood lipid, improve the body composition, and maybe contribute to the prevention of long-term chronic diseases.

OBJECTIVETo evaluate the diagnostic value of dynamic monitoring of C-reactive protein (CRP) in drainage fluid in predicting early anastomotic leakage after colorectal surgery.

METHODSThis study enrolled 172 patients, who were diagnosed as colorectal cancer before operation and underwent radical surgery, without residual tumor tissues by postoperative pathology and perioperative infection, at the Tianjin Medical University Cancer Hospital between July 2015 and January 2016. The C-reactive(CRP) protein level in drainage fluid was continuously monitored from postoperative days (POD) 1 to 5. CRP level was compared between anastomotic leakage (AL) group and non-anastomotic leakage (NAL) group. Receiver operating characteristics (ROC) curve was used to estimate the value of monitoring CRP in drainage fluid to predict anastomotic leakage after colorectal surgery.

RESULTSAmong 172 patients, 101 cases were male and 71 cases were female, with age of (59.9±10.3) years. Anastomotic leakage occurred after colorectal surgery in 24 cases(14.0%, AL group ) and other 148 cases were defined as NAL group. Other than body mass index (BMI), differences in baseline data were not statistically significant between two groups. The CRP lever in AL group and NAL group showed rising trend from POD1 to POD4 [Day 1: (6.7±8.4) g/L vs. (8.0±10.6) g/L; Day 2: (24.8±14.6) g/L vs. (28.3±21.1) g/L, Day 3: (54.8±26.5) g/L vs. (53.8±27.6)g/L, Day 4: (62.0±32.2) g/L vs. (58.4±30.7) g/L], while the differences were not significant (all P>0.05). At POD 5, the CRP lever of AL group increased continuously, while that of NAL group decreased with significant difference [(65.3±38.9) g/L vs. (44.7±39.5) g/L, t=-2.85, P=0.005]. Further stratification analysis on AL group revealed CRP level in early AL (AL occurrence POD 10) showed rising trend from POD 1 to 4, then decreased slightly at POD 5, but whose differences were not significant (all P>0.05). ROC curve was drawn with AL condition as state variables and CRP level as test variables. The AUC of POD 1 to 4 was 0.425, 0.487, 0.510, 0.522 respectively and the AUC of POD 5 was the largest, 0.657 (95%CI:0.537-0.777). The largest Youden Index was 0.274. The critical value of CRP was 27.15 g/L. When this value was used as the point of tangency to predict the occurrence of AL, the sensitivity was 87.5%, the specificity was 39.9%, positive predictive value was 19.1%, and negative predictive value was 95.2%.

CONCLUSIONContinuous increase of CRP level in abdominal drainage fluid from POD 1 to POD 5 indicates the occurrence of AL after colorectal cancer operation, especially the detection of CRP level at POD 5 is important.
