Acta Nutrimenta Sinica 1956;0(01):-
Dietary survey in lactating mothers and analysis of composition of breast milk were performed. 73 healthy women, full term and normal delivery, 21-32 years of age, without family history of "insufficient milk secretion" or environmental, psychiatric and emotional disturbance were included in this study. 33 of them were female workers in the urban district and 40 of them were peasant women in the countryside. By comparing the daily dietary nutrient intakes of the urban and rural groups of lactating mothers with that recommended by the Chinese Nutrition Society (1981 revised), one can see that except iron and thiamine, all the others were below the standard recommended. Among these, total calories were only 82.7% and 77.3% respectively, protein 80.6% and 73.1%, riboflavin 96.7% and 41.1%, calcium 21.9% and 25.2% respectively. Intake of animal protein, total fat and fat energy ratio of the urban group were higher than that of the rural group, meanwhile the content of protein, fat and zinc in the breast milk of the urban group were also higher than that of the rural group, By stepwise regression analysis the following regression function was conducted;Y = 0.9-107 + 0.007x, Y represent the estimated protein content in the breast milk, and x, the fat energy ratio in the mothers diet. Positive correlation was seen between the dietary intake of animal protein and zinc content in the breast milk. r=0.47, p

Objective To investigate the effect of placing subcutaneous drain tube and preseting triclosan-coated polyglactin 910 suture with delayed suturing to incision infection after typeⅢabdominal surgery. Methords Dividing 504 patients with typeⅢincisions undergone abdominal surgery into 3 groups. The number of group A patients with thoroughly incision washing and primary triclosan-coated polyglactin 910 suture after abdominal surgery was 143. The number of group B with closed anterior rectus sheath, opened skin and subcutaneous fat with preseted triclosan-coated polyglactin 910 suture was 190. The number of group C with subcutaneous drain tube after abdominal surgery was 171. We compared the incidence rates of incision infection and the second phase debridement suture rates among the 3 groups. Results For the group A, B, C, the number of incision infection people was 11, 4, 3 and the incision infection rate was 7.69%, 2.11%and 1.75%respectively. The difference of the 3 groups incision infection rate were statistically significant (P<0.05). The incision infection rate of the group B and group C were lower than that of group A and the difference were statistically significant (P<0.016 7). There were no significant differences in second phase debridement suture rates among the 3 groups. Conclusion Preseting triclosan-coated polyglactin 910 suture with delayed incision sutue and placing subcutaneous drain tube can decrease the incision infection rates for type Ⅲpatients after abdominal surgery, but can not decrease the second phase debridement suture rates of the infectious incision.

Objective To evaluate the clinical efficacy of transcatheter super-selective hepatic artery embolization (TAE) in treating symptomatic polycystic liver disease (PLD). Methods A total of 8 patients with PLD, who were admitted to authors’ hospital during the period from 2009 to 2013 to receive TAE, were enrolled in this study. The patients included 6 females and 2 males with a mean age of 59.5 years (54-65 years). The used embolic agents were polyvinyl alcohol (PVA) microspheres and micro spring coils. Both plain and contrast-enhanced CT scans of the upper abdomen were performed before TAE as well as at 12 months after TAE; the total volume of the hepatic cysts was measured and the changes of the cystic volume were determined. Statistical analysis was conducted using paired t test. Results The technical success rate was 100%. After TAE, the patients developed fever and different degrees of discomfort at liver area, which were disappeared after active symptomatic medication, and no serious complications occurred. The patients were followed up for 12 months , the mean total volume of the intrahepatic cysts decreased from preoperative (5 794±2 066) cm3 (range 3 120-8 935 cm3) to postoperative (3 832±1 525) cm3 (range 2 019-5 925 cm3), the difference was statistically significant (t=6.971, P<0.001). The reduction ratio of total volume of intrahepatic cysts was 34.6%±11.3%(24.3%-60.4%). Conclusion For symptomatic polycystic liver disease, transcatheter super-selective hepatic arterial embolization is a newly-developed treatment. This technique is safe and effective with reliable response and fewer complications. Therefore, it should be recommended in clinical practice.
