Objective To develop a new method of preparing anti-Rh(D) reagent serum in order to help overcome the shortage of Rh(D) negative red blood cells(RBCs). Methods Anti-Rh(D) containing type A and B sera were mixed. Through dilution and neutralization, the titer of complete antibodies decreased to 2. Anti-Rh(D) saturated Rh(D)positive RBCs were prepared by adding anti-Rh(D) containing serum to Rh(D) positive RBCs so that all the Rh factors on the cells were saturated. The anti-Rh(D) saturated type A and type B RBCs were added to the mixed plasma to absorb the remaining anti-A and anti-B. Results The acquired regent sera had a high anti-Rh(D) titer with a high specificity. Conclusion Anti-Rh(D) saturated Rh(D) positive RBCs absorption after neutralization can help with the production of human origin anti-Rh(D) reagent serum and save a large amount of Rh(D) negative evythvocytes.

Objective To investigate the distribution characteristics of serum small dense low density lipoprotein-cholesterol (sdLDL-C) levels in healthy normolipidemia and hyperlipidemia and analyze the correlation between sdLDL-C and other serum lipids.Methods Totally 1012 normolipidemic subjects (18 93 years old,503 male,509 females) were grouped according to gender and age (18 -29,30 -69 and ≥70 years old).And 433 hyperlipidemic subjects (23 -90 years) were divided into the following 3 groups based on fasting triglyceride (TG) and low density lipoprotein-cholesterol (LDL-C)levels:hypertriglyceridemia (n =165 ),high-LDL-C ( n =129) and combined hyperlipidemia ( n =139 ).The sdLDL-C and other serum lipids were measured by Olympus AU2700 automatic analyzer.Analysis of Variance and Kruskal-Wallis H test was used for statistical analysis.Results The distribution of the sdLDL-C levels in normolipidemic subjects was near normal distribution.The sdLDL-C levels had differences in gender and age.In the 18 -29 and 30 -69 years old group,the mean values of sdLDL-C were significantly higher in males than in females [ (0.55 -0.21 ) mmol/L vs (0.47 ±0.22) mmol/L,t =2.212,P =0.028 and (0.66±0.28) mmol/L vs (0.62±0.25) mmol/L,t =2.121,P=0.034].In the ≥70 years old group,the difference of sdLDL-C levels in gender was not statistically significant [ male ( 0.54 ± 0.21 )mmol/L vs female (0.54 ± 0.22 ) mmol/L,t =0.022,P =0.982] ; the mean value was ( 0.54 ± 0.22 ) mmol/L The hyperlipidemic subjects had conspicuous higher levels of sdLDL-C compared with normolipidemia [ ( 1.25 ±0.44) mmol/L vs (0.60 ±0.26) mmol/L,t =29.306,P ＜0.001 ].Among all of groups,the combined hyperlipidemia group had the highest sdLDL-C level [ ( 1.52 ± 0.49) mmol/L,F =525.66,P ＜0.001 ] ; the hypertriglyceridemia group had the highest sdLDL-C/LDL -C level (0.47 ±0.12,F =287.93,P ＜0.001 ) and the high-LDL-C group had the highest level of non-sdLDL-C [LDL-C subtract sdLDL-C,(2.71 ± 0.52) mmol/L.F =336.32,P ＜ 0.001 ].The sdLDL-C showed a good positive correlation with TC,TG,LDL-C,ApoB and BMI ( rs =0.66,0.68,0.65,0.79 and 0.27,P ＜ 0.001 ),and negative correlation with HDL-C and ApoA1 ( rt =- 0.42 and - 0.37,P ＜ 0.001 ).Based on partial correlative analysis,sdLDL-C showed a different correlation with TG,LDL-C and TC ( r =0.42,0.28 and 0.15,P ＜ 0.001 ).Conclusions LDL-C and TG are the important factors influencing the sdLDL-C levels.However,TG has greater effect than LDL-C.The sdLDL-C is an appropriate and good index to evaluate the small dense low density lipoprotein (sdLDL) mass and the overall situation of lipid metabolism.In order to make full use of sdLDL in the clinical treatment and health assessment,it is necessary to establish sdLDL-C reference intervals through the survey of distribution of sdLDL-C levels in different geographic areas.

Some documents had reported that plant-derived smoke water showed prominent effects of promoting seed germination, seedling growth and fruit quality of crops and horticultural plants. Recently, researches had also focused on the significant activity of smoke water in improving the yield and quality of medicinal plants, which provided new ideas for increasing the medicinal plants yield and quality. In this paper, physiological effects, active component, and mechanism of smoke water and its application in medicinal plants were summarized, which can be used as references of more value for the further development of medicinal plants.

Objective To study the serum small dense low density lipoprotein-cholesterol (sdLDL-C)concentration in patients with clinical and sub-clinical primary hypothyroidism,and to explore the clinical significance of serum sdLDL-C determination in pa-tients with hypothyroidism.Methods 60 patients with clinical hypothyroidism(clinical hypothyroidism group),96 cases with sub-clinical hypothyroidism(sub-clinical hypothyroidism group)and 132 normal subjects (normal group)were enrolled in the study. FT3,FT4,thyroid stimulating hormone (TSH),TG,TC,HDL-C,LDL-C,apolipoprotein AⅠ(ApoAⅠ),apolipoprotein B (ApoB), and sdLDL-C concentrations were measured.Analysis of Variance,Kruskal-Wallis H test and Spearman rank correlation analysis were used for statistical analysis.Results The concentration of sdLDL-C in sub-clinical hypothyroidism group was significantly higher than that in normal group (t=5.78,P <0.01),the concentration of sdLDL-C in clinical hypothyroidism group was signifi-cantly higher than that in sub-clinical hypothyroidism group(t=-2.88,P <0.01)and in normal group (t=6.68,P <0.01).There was statistically significant difference among groups (F =37.66,P <0.01).Correlation analysis showed that sdLDL-C in primary hypothyroidism patients was positively correlated with LgTSH (r =0.203,P =0.011 ),and negatively correlated with FT4 (r =-0.169,P =0.035).Conclusion The high concentration of sdLDL-C is a manifestation of dyslipidemia in primary hypothyroidism patients,and an important risk factor for atherosclerosis in primary hypothyroidism patients.

? AlM: To evaluate the efficacy of the method of vitrectomy combined with posterior sclera reinforcement for retinal detachment due to macular hole in high myopia.
?METHODS:From January 2012 to December 2013, in 45 eyes of 45 high myopic patients with retinal detachment due to macular hole, 28 eyes were in group A of vitrectomy with posterior sclera reinforcement and 17 eyes were in group B of vitrectomy. Preoperative examinations included visual acuity, intraocular pressure, indirect ophthalmoscopy and OCT were performed. ln follow - up 6 to 12mo, postoperative examinations of visual acuity, OCT were performed and effects of retinal reattachment and macular hole closure were compared between the two groups.
?RESULTS: ( 1 ) Postoperative examinations: visual acuity was 1. 19±0. 39 in group A and 1. 51±0. 34 in group B. The differences were statistically significant(P<0. 05). (2) The retinal reattachment rate was 100% in group A and 88. 24% in group B. There was no statistical significance between them(P>0. 05). (3) The macular hole closure rate was 82% in group A and 53% in group B. The differences were statistically significant(P<0. 05).
? CONCLUSlON: The treatment of vitrectomy with posterior sclera reinforcement is safe and feasible, which could improve visual acuity and increase the rate of macular hole closure in treating retinal detachment due to macular hole in high myopia.
