Objective:To investigate the effect of neonatal breast crawling exercise on breastfeeding and psychological state of primiparas who delivered vaginally.Methods:Using convenience sampling method, 86 pairs of normal term infants and mothers who delivered vaginally in the First People′s Hospital of Yancheng from January 2019 to January 2020 were selected as the research objects, and divided into experimental group and control group according to the random number table method, there were 43 pairs in each group. The control group was given routine postpartum care, while the experimental group was given neonatal breast crawling exercise on the basis of routine postpartum care. The time of initiation of lactation, the success rate of first breastfeeding and the score of first Breastfeeding Assessment Tool (BAT) were compared between the two groups. The rates of exclusive breastfeeding, the scores of Breastfeeding Self-efficacy Scale Short Form (BSES-SF) and the scores of Edinburgh Postnatal Depression Scale (EPDS) were compared between the two groups at 72 h and 42 d after delivery respectively.Results:The time of initiation of lactation was (48.36 ± 6.12) h in the experimental group, which was significantly earlier than that in the control group(52.86 ± 7.29) h, the difference was statistically significant (t=3.08, P<0.05). The success rate of first breastfeeding and the BAT scores of the experimental group were 88.1% (37/42) and (9.74 ± 1.33), respectively, which were significantly higher than those in the control group 69.8% (30/43) and (8.84 ± 1.60), the differences were statistically significant (χ 2=4.28, t=2.82, both P<0.05). At 72 h and 42 d after delivery, the rate of exclusive breastfeeding were 42.9%(18/42) and 86.49%(32/37) in the experimental group, significantly higher than those in the control group 20.9% (9/43) and 60.00% (24/40), the differences were statistically significant (χ 2=4.71, 3.93, both P<0.05). At 72 h and 42 d after delivery, the BSES-SF scores were (38.48 ± 6.34) and (45.43 ± 11.45) in the experimental group, which were significantly higher than those in the control group (35.21 ± 4.87) and (40.10 ± 10.82), the differences were statistically significant (t=2.66, 2.10, both P<0.05); the EPDS scores were (5.52 ± 1.53) and (7.38 ± 2.25) in the experimental group, which were significantly lower than those in the control group (6.26 ± 1.63) and (8.73 ± 2.39), the differences were statistically significant (t=2.13, 2.54, both P<0.05). Conclusions:Neonatal breast crawl is an effective way to promote the breastfeeding. It can also enhance maternal confidence and alleviate maternal psychological status.

Objective To investigate the value of delayed 18F-FDG PET/CT with oral intake small dosage diuretics for diagnosing urogenital cancers.Methods Patients with suspected urogenital system cancers were divided into routine dosage diuretic group (n=12) and small dosage diuretics group (n=35).All patients underwent whole-body PET/CT followed by delayed scanning after oral 40 mg or 20 mg Furosemide respectively.The urine maximum standard uptake value (SUVmax) and T/U (the ratio of urine and lesion SUVmax) before and after diuresis were compared respectively.Diagnostic efficacy for malignant urogenital system cancers of small dosage group was calculated.Results The urine SUVmax and T/U were statistically different between routine whole body and delayed scans in both groups (P＜0.05).SUVmax and T/U of routine and delayed scans had no statistical differences between the two groups (P＞0.05).In small dosage group,the sensitivity,specificity,positive predictive value,negative predictive value and accuracy of delayed imaging and routine imaging was 96.77％ (30/31)and 61.29％ (19/31),75.00％ (3/4) and 50.00％ (2/4),96.77％ (30/31) and 90.48％ (19/21),75.00％ (3/4)and 14.29％ (2/14),94.29％ (33/35) and 60.00％ (21/35),respectively.The sensitivity and accuracy were statistically different between routine and delayed imaging (P＜0.001).Conclusion Delayed PET/CT imaging with oral small dosage Furosemide has the same efficacy as PET/CT using routine dosage diuretics,which is useful for diagnosing urogenital cancers.
