Objective To evaluate the value of serum retinal-binding protein (sRBP) in diagnostic work-up of nephropathy. Methods sRBP was assayed by using immunological turbidimetry on HITACHI 7170. Results sRBP levels in the 9 types of nephropathy were: nephritic syndrome (161.57±83.68)mg/L, uremia (358.52±127.96)mg/L, systemic lupus erythematosus nephropathy (164.49±106.98)mg/L, chronic renal failure (348.42±141.12)mg/L, diabetic nephropathy (261.78±144.73)mg/L, chronic glomerulonephritis (274.69±129.97)mg/L, chronic...

Objective To evaluate the value of serum retinal-binding protein (sRBP) in diagnostic work-up of nephropathy. Methods sRBP was assayed by using immunological turbidimetry on HITACHI 7170. Results sRBP levels in the 9 types of nephropathy were: nephritic syndrome (161.57±83.68)mg/L, uremia (358.52±127.96)mg/L, systemic lupus erythematosus nephropathy (164.49±106.98)mg/L, chronic renal failure (348.42±141.12)mg/L, diabetic nephropathy (261.78±144.73)mg/L, chronic glomerulonephritis (274.69±129.97)mg/L, chronic renal dysfunction (253.17± 148.12 )mg/L, acute pyelonephritis (66.80±36.31)mg/L, hypertensive nephropathy (222.73±166.02)mg/L, and the healthy control was 71.79±24.50 mg/L. sRBP level was significantly higher in groups with nephropathy than that in the healthy controls (P<0.05), except the group with acute pyelonephritis. sRBP was significantly correlated with serum β_2-MG(P<0.01). Furthermore, sRBP was most closely correlated with other renal indices in systemic lupus erythematosus nephropathy and chronic glomerulonephritis than the others. Conclusions sRBP is a valid index in evaluation of nephropathy.

目的探讨血清视黄醇结合蛋白(sRBP)在肾脏疾病中的应用价值。方法在HITACHI7170全自动生化仪上采用免疫透射比浊法浊定sRBP,并进行相关的统计学分析。结果9组肾脏疾病患者sRBP的结果为:肾病综合征(161.57±83.68)mg/L,尿毒症(358.52±127.96)mg/L,系统性红斑狼疮肾病(164.49±106.98)mg/L,慢性肾功能衰竭(348.42±141.12)mg/L,糖尿病肾病(261.78±144.73)mg/L,慢性肾小球肾炎(274.69±129.97)mg/L,慢性肾功能不全(253.17±148.12)mg/L,急性肾盂肾炎(66.80±36.31)mg/L,高血压肾病(222.73±166.02)mg/L;对照组为(71.79±24.50)mg/L,除急性肾盂肾炎组外,各肾病组明显高于对照组(P<0.05)。比较常规血清肾功能检测项目,sRBP与sβ2-MG显著相关(P<0.01),系统性红斑狼疮肾病和慢性肾小球肾炎组sRBP与各项肾功能指标相关性好。结论sRBP可以作为反映肾脏滤过功能异常的较敏感指标。

Objective As an extended study of β-Carotene-vitamin A equivalence in Chinese adults, we carried out an experiment on 10 (5 males and 5 females) rural volunteers aged 38-49 years, which would be complementary to the early reported study on subjects aged 50-60 years.Methods Ten healthy Chinese adult volunteers aged 38-49 years were recruited in a 56 days experiment, which included residency in the Metabolic Research Unit (first 10 days) and in home (last 46 days). A physiological dose of 2H_8 β-C (11,011(nmole or 6mg) in oil was given with a liquid diet (25 % energy from fat) to the volunteers in the first day of the experiment. Three days after the 2H_8 β-C dose, each volunteer took a reference dose of 2H_8 retinyl acetate (8,915 nmole or 3mg) in oil with the same liquid diet. Serum samples were collected at 0, 3, 5, 7, 9, 11 and 13 hours of the first and the fourth days of study, and fasting serum samples were also collected daily in first 10 days and then weekly at morning of 14th, 21st, 28th, 35th, 42nd, 49th and 56th day after a 12-hours overnight fast. Serum retinol and carotenoids concentrations were measured by high performance liquid chromatography (HPLC). Also retinol fraction was extracted from serum and isolated by HPLC. The serum retinal enrichments were determined by using gas chromatograph/mass spectrometry with electron capture negative chemical ionization (GC-MS). Results The average 52-day area under the serum 2H_4 retinol response curve (from the 2H_8 β-C dose) was (1289±547) nmol/d and the 52-day area under the serum 2H_8 retinol response curve (from the 2H_8 retinyl acetate dose) was (3560±1058) nmol/d. By using 2H_8 retinyl acetate as the vitamin A reference, the 2H_4 retinol formed from 2H_8 β-C (11,011 nmol) was calculated to be equivalent to (3434±1449) nmol of retinol. The calculated conversion factor of β-C to retinol ranged from 2.00-9.61 to 1 with an average of (3.89±2.76) to 1 on a molar basis, or 3.76-18.05 to 1 with an average of (7.30±5.18) to 1 on a weight basis.Conclusion The conversion of β-C to vitamin A in 10 middle-aged Chinese adults had been quantitatively determined by using a stable isotope reference method, and an average conversion ratio of 7.30∶1 to 1 on a weight basis was found in this study.

BACKGROUND: Vitamin A deficiency disorders VADD is a healthy problem of children in the world, especially in the west of China and remote areas, and the nutritional intervention is needed. OBJECTIVE: To compare the improved effects of biscuits fortified with three different doses of vitamin A on the vitamin A status in children aged 3-6 years and explore an ideal dose of vitamin A supplement for preventing VADD. DESIGN: Randomized controlled observation. SETTING: Health Surveillance Institute, Chongqing Municipal Health Bureau; Staff Room of Nutrition and Food Hygiene, College of Public Health, Chongqing University of Medical Sciences; Center for Children Nutrition, Children's Hospital, Chongqing University of Medical Sciences. PARTICIPANTS: The investigation was done between March and December 2002. 753 children aged 3-6 years from 8 kindergartens in Banan district of Chongqing city were enrolled with the agreement of their guardians. They were divided randomly into 4 groups: 30% recommended intake group, 100% recommended intake group, 20 000 international unit IU and 200 000 IU groups. METHODS: ① The biscuits fortified with 30% recommended intake of vitamin A (500 IU) were once given to people of the 30% recommended intake group 177 cases every day. ②The biscuits fortified with 100% recommended intake of vitamin A (1666 IU) were once given to people of the 100% recommended intake group 173 cases every day. ③The biscuits fortified with 20 000 IU of vitamin A were once given to people of the 20 000 IU group 209 cases every week. ④The soft gelatin capsule with 200 000 IU of vitamin A were once given to people of the 200 000 IU group 194 cases. Height, body mass, serum retinal, prealbumin, haematoglobin and retinal binding protein of all children were measured before intervention and after intervention for 3 months. Above indexes were rechecked after supplement for 9 months in 87 children of 30% recommended intake group MAIN OUTCOME MEASURES: ①Prevalence rate of VADD before intervention and after intervention for 3 months in children of every group. ②Serum retinal, serum prealbumin, serum retinal binding protein, haematoglobin, height and body mass of children before intervention and after interventional for 3 months in every group. RESULTS: Because of lose of samples and detective technology, only 580 children' examination results were got by rechecking. ①Comparison of the prevalence rate of VADD of children in every group: Three months supplementation later, the prevalence of VADD in every group all decreased significantly 1.48%,1.42%,1.21%, 2.16%;6.78%,6.54%,8.61%,8.25%(χ2=3.86-8.57, P < 0.05-0.01). ②Comparison of serum retinal, serum prealbumin, serum retinal binding protein, haematoglobin, height and body mass of children of every group: After supplement for 3 months, except prealbumin and haematoglobin in the 30% recommended intake group , other indexes in each group all increased significantly (t=2.52-37.44, P < 0.05-0.01). The increase of serum vitamin A in the 20 000 IU group was larger than that in the other groups (F=4.62,P< 0.01). The increases of haematoglobin, prealbumin and height in the 30% recommended intake group were less than those in the other groups (F=5.04-7.78,P < 0.01). After supplement for 9 months, the increases of haematoglobin and prealbumin in the 30% recommended intake group were larger than those in the other groups (F= 11.62,10.21,P < 0.01). The increase of serum retinal was still lower than that in the 20 000 IU group (F=4.21,P < 0.01=. CONCLUSION: Supplement with biscuits fortified with 3 different doses of vitamin A and capsule with 200 000 IU of vitamin A can improve obviously the nourished status of vitamin A and the level of ferrohemoglobin, in which 30% recommended intake and 100% recommended intake have small risk, and everyday supplement can maintain stably the level of vitamin A. That may be suitable for the long-term supplement for children, and the effect of 30% recommended intake was better than that of 100% recommended intake.
