Objective To analyze the contribution of dietary supplements to current vitamin mineral intakes in Beijing,China.Method By stratified cluster sampling method,3992 subjects aged 18y and above in 1440 households were investigated in 6 different regions in Beijing.Results The dietary intake of vitamin and mineral of men was higher than that of women,but the total intake of niacin and vitamin C was lower.Both dietary and total intake of vitamin and mineral in supplement users were higher that those in nonusers.In the group of supplement users,the contribution of supplement to thiamin,riboflavin and calcium intakes was 60% and 70%,47% and 45%,42% and 45% in men and women respectively.The percentage of supplement users who reached the current recommended intakes of vitamins and minerals was higher compared with that of nonusers,about 20 -30 percent higher for vitamin C and calcium.Conclusion The average intakes of vitamin and mineral are improved by using dietary supplements.Dietary supplements should be included in the future nutrition survey in China for improving the accuracy of nutrient’s intake.
2.Intraoperative radiotherapy for rectal cancer.
Chinese Journal of Gastrointestinal Surgery 2014;17(3):212-214
Radiotherapy, surgery and chemotherapy are the main treatments for cancer. Though intraoperative radiotherapy(IORT) for rectal cancer is still at its preliminary stage in China, patients can get more benefits from IORT than pre- or post-operative radiotherapy. IORT improves local control for locally advanced rectal cancer and improves overall survival rate of locally recurrent rectal cancer. In general, IORT is safe and feasible. It will be widely used for patients with rectal cancer in the future.

OBJECTIVEThe survey will reveal current status of subclinical vitamin A deficiency (SVAD) and explore its affecting factors in children of China.
METHODSTotally 8 669 children aged under 6 years were randomly selected from 14 provinces for clinical examination, health and dietary questionnaire and serum level of vitamin A measurement with fluorescence method. The cut-off value for SVAD was defined as = 0.70 micro mol/L.
RESULTSPrevalence of SVAD was 11.7% and that of suspected SVAD 39.2% in all subjects, which decreased with the increase of gross domestic product, average annual family income, mother's schooling and children's age. Prevalence of SVAD and suspected SVAD higher in rural areas (15.0%) than in urban areas (5.2%), and higher in children with a minority mother (22.6%) than in those with a Han nationality mother (8.7%). Prevalence of SVAD and suspected SVAD was higher in children whose blood samples were collected within one week in-taking vitamin A-rich food (12.6%-22.6%) than those in-taking vitamin A daily (4.1%-10.0%), and higher in children suffering from respiratory infection, fever and diarrhea two weeks before their blood collection (15.2%-20.3%) than in those without those diseases (10.1%-11.1%). Logistic regression analysis showed that poor family economic status, living in rural areas, children with a minority mother, younger age, no-dairy milk products intake, and respiratory infection and fever all were risk factors for SVAD.
CONCLUSIONSMore than half of children under six years old in China (50.9%) had vitamin A nutrition problem. Varied factors played roles to different extent in SVAD in children.

Objective:To study the clinical application of ultrasound-guided puncture and catheter tip positioning in peripherally inserted central catheter (PICC) among very/extremely low birth weight infants (VLBWI/ELBWI).Method:From January 2019 to August 2020, VLBWI/ELBWI admitted to NICU of our hospital and received PICC were prospectively enrolled in the study. Based on the last digit of medical record number was odd or even, the infants were assigned into ultrasound group and X-ray group. In the ultrasound group, puncture and catheter tip positioning were performed at bedside guided by ultrasound, while in the X-ray group, these procedures were performed empirically. The differences of catheterization procedure duration, first-time success rate, the visibility of catheter tip, primary dislocation rate, secondary dislocation rate and complication rate were compared between the two groups using SPSS 25.0.Result:A total of 118 premature infants were enrolled, including 57 cases in ultrasound group (50 cases VLBWI and 7 cases ELBWI) and 61 cases in X-ray group (54 cases VLBWI and 7 cases ELBWI). The catheterization procedure duration [(23.2±7.1) min vs. (34.1±7.5) min], first-time success rate (93.0% vs. 65.6%), the visibility of catheter tip (96.5% vs. 83.6%), primary dislocation rate (7.0% vs. 24.6%) and complication rate (7.0% vs. 21.3%) in ultrasound group were all better than X-ray group ( P<0.05). For ELBWI, the above five indexes in the ultrasound group were better than the X-ray subgroup ( P<0.05). For VLBWI, only the catheterization procedure duration and first-time success rate were better in the ultrasound group than the X-ray group ( P<0.05). Conclusion:Ultrasound-guided PICC catheterization in VLBWI/ELBWI is convenient and accurate, which can improve success rate, reduce radiation exposure and repeated catheterization injury. Timely tracking and adjustment of the catheter under ultrasound can reduce complications after catheterization. This technique is worth popularizing among VLBWI/ELBWI.

Objective:To compare the myocardial protection in pediatric patients undergoing living-donor liver transplantation (LDLT) performed under propofol- versus desflurane-based anesthesia. Methods:Sixty American Society of Anesthesiologists Physical Status classification Ⅲ or Ⅳ pediatric patients of both sexes, aged 5-24 months, weighing 5-15 kg, scheduled for elective LDLT under general anesthesia, were divided into 2 groups ( n=30 each) using a random number table method: propofol group (group P) and desflurane anesthesia group (group D). During anesthesia maintenance, propofol 5-10 mg·kg -1·min -1 was intravenously infused in group P, desflurane 0.65 MAC-1.30 MAC was inhaled in group D. At 5 min after induction of anesthesia, at 1 h of reperfusion, at the end of surgery, at 1, 2, 3, 7 and 14 days after surgery, and on the day of discharge, the concentrations of serum high-sensitivity cardiac troponin I, creatine kinase isoenzyme, N-terminal pro-B-type natriuretic peptide were determined by enzyme-linked immunosorbent assay, the occurrence of nausea and vomiting, agitation, and shivering, postoperative tracheal extubation time, intensive care unit stay time, and postoperative length of hospital stay were recorded within 24 h after surgery. Results:Compared with group P, the concentrations of serum high-sensitivity cardiac troponin I and creatine kinase isoenzyme were significantly decreased after surgery, the extubation time and intensive care unit stay time were shortened ( P<0.05), and no significant change was found in serum N-terminal pro-B-type natriuretic peptide concentrations, postoperative length of hospital stay and incidence of postoperative adverse effects at each time point in group D ( P>0.05). Conclusions:Desflurane has better myocardial protection than propofol in pediatric patients undergoing LDLT, which is helpful for early prognosis.
