Objective To establish a new method for the determination of quercetin and kaempferol in wine by high performance liquid chromatography (HPLC) with chemiluminescence. Methods The procedure was based on the chemiluminescent enhancement by quercetin and kaempferol of the K3Fe(CN)6 system in an alkaline medium. The HPLC with post-column chemiluminescence was established for the determination of quercetin and kaempferol in wine. Results The standard curves were linear in the concentration ranges of 2.0?10-6-1.6?10-2 g/ml(r=0.999 0)for quercetin and 3.2?10-6-2.0?10-4 g/ml(r=0.999 8)for kaempfero respectively.The limits of detection were 1.4 ?10 -9 g/ml for quercetin and 3.4 ?10 -7 g/ml (S/N =3)for kaempfero respectively. The rates of recovery were 99.31% for quercetin and 99.06% for kaempferol. Conclusion The method is simple,rapid,accurate and applicable to the determination of quercetin and kaempferol in wine.

Objective To know how large platelets influnece the platelet count difference of the optical and impedance methods so as to provide the support for the reasonable application of optical method and effectively increasing the accuracy of platelet count.Methods 132 blood routine specimens with normal RBC parameters were anaylzed by both electrical impedance and optical methods with the Sysmex-XE5000 fully automativ hematology analyzer.The data were divided into the large platelet group and the normal platelet group according to the platlet-large cell ratio(P-LCR)results.The RBC and platelet parameters were compared be-tween the two groups with the unpaired t-test and the platelet count results detected by the optical and electrical impedance methods were compared within group with the paired t-test.Results The extremely significant differences of platelet parameters existed be-tween the two groups.The P-LCR,MPV,PDW and IPF % of the large platelet group were significantly higher than those of the normal platelet group,but the RBC parameters had no obvious difference.The significant difference of the platelet count also existed between the electrical impedance and optical methods in the large platelet group(P <0.05 ),the platelet count results detected by the electrical impedance method was on the low side,but the normal platelet group had no significant difference.Conclusion P-LCR increase is related with the increase of immature platelet.The electrical impadence method conducts the differentiation according to the granular size,which is easy to exclude the large platelel with larger volume and leads to reduce the platelet count results.There-fore,when P-LCR is increased,the optical method should be adopted in conducting the platelet count for avoiding the false reduce caused by the electrical impedance method.

Objective To investigate the reference ranges of peripheral white blood cells (WBC) and five classification parame‐ters among 13 442 apparently healthy children to provide reference for clinical diagnosis .Methods A total of 13 442 apparently healthy children aged from 1 month old to 5 years undergoing the health physical examination in the healthcare department of the Guangzhou Municipal Women and Children Medical Center were chosen according to the healthy children screening standard and the exclusion standard of hematological diseases ,infection diseases and drug administration history .The WBC analysis and its parame‐ters detection were performed by using the Sysmex XS‐800i automatic blood cell analyzer .Results WBC and its five classification parameters were not accorded with the normally distribution .By the Mann‐whitney test ,no statistically significant differences in WBC ,BASO# and NEU # were detected between different genders of children (P> 0 .05) ,while the differences in LYM # , MONO# and EOS# had statistical significance(P<0 .001) ,in which the LYM # level in females was significantly higher than that in males ,while the MONO# and EOS# levels in females were lower than those in males ;By the Kruskal‐Wallis test ,WBC and five classification parameters had statistically significant differences among different age groups (P<0 .001) .The parameters of WBC ,LYM # ,MONO# and EOS# were decreased with age increase ,while NEU # was constantly increased with age increase and BASO# was decreased with age increase before 4 years old .Conclusion All factors such as gender ,age should be The inde‐pendent reference rangesl of WBC parameters among children aged from 1 month old to 7 years old should be formulated on the ba‐sis of fully considering the factors such as gender ,age .

Objective To explore the effectiveness of our self-designed 3D printing relay template in the treatment of malunion of irregular intra-articular ankle fractures.Methods From October 2013 to October 2015,our self-designed 3D printing relay template was used in 14 patients with severe malunion of intra-articular ankle fracture to assist their intra-articular osteotomy.They were 10 males and 4 females,with an average age of 40.5 years (from 34 to 59 years).Thin slice CT scan was preformed preoperatively for all the ankles involved.The computer fictitious tibial and fibular models for location and osteotomy navigation templates were acquired from the data of CT scan after processing,design and reconstruction by software.After the navigation templates which fit the size of solid ankle were printed by a 3D printer,they were sterilized and reserved.The guide plates were used in turn during operation.The irregular malunited bone blocks in the posterior malleolus were completely resected along the osteotomy template.After fracture reduction,the bone blocks were stabilized with internal fixation.Fracture union time was recorded.Scores of visual analogue scale (VAS),American Orthopaedic Foot and Ankle Society (AOFAS) and the short form-36 (SF-36),ankle ROM and complications were also recorded at the final follow-ups.Results The 14 patients obtained an average follow-up of 28.6 months (from 14 to 35 months).Bony union was achieved after an average of 3.7months (from 3 to 6 months).At the final follow-ups,on average,VAS score (2.2 ± O.8),AOFAS ankle and hindfoot score (81.1 ± 6.8),SF-36 score (82.5 ± 5.2),dorsal extension (27.5 ° ± 2.5°),and plantar flexion (24.2° ±6.3°) were significantly improved compared with the preoperative values (6.3 ± 1.8,43.1 ± 12.0,37.6 ± 9.9,14.1° ± 3.8° and 14.4° ± 3.9°,respectively) (P ＜ 0.05).No implant failure,soft tissue complications or post-traumatic arthritis occurred during the follow-up.Conclusion Since our self-designed 3D printing relay templates for osteotomy can accurately position the fracture lines of the distal tibia via limited incision and invasion,they help a lot in precise osteotomy and anatomical reduction of malunited intra-articular ankle fracture,preventing incidence of traumatic arthritis.

Objective To evaluate the advantage of 3D printing technique in treatment of complicated ace-tabula fracture,we compared the early clinical outcomes of surgical treatment for complex acetabula fracture with traditional surgery(group A)and that assisted by 3D printing technique(group B).Methods A prospective anal-ysis of 35 complicated acetabula fractures was performed at our department,13 patients cured assisted with 3D printing technique. The other 22 patients performed traditional surgery. Surgical trauma,systematic inflammation, immediate reduction effect were evaluated by Matta image assessment standard,and rehabilitation functional status evaluated by Harris score system and Merled' Aubigne and Postel Grading standard. Results There were signifi-cant differences between the two groups regarding intraoperative blood loss,postoperative drainage,operation time (P<0.05),and group B was superior to group A.C reactive protein,leucocyte and creatine kinase MM in periph-eral blood in group A were much higher than those in group B at 24 hours postoperatively(P<0.01).The result of reduction of fracture is poor in group A,but excellent rate of reduction is about 84% in group B. The result of Merled' Aubigne and Postel scores grading was superior in group B(P = 0.013). The excellent and good rate of Harris function score in B group was significantly higher than that in group A(P=0.027).Conclusion The treat-ment of complicated acetabula fracture assisted by 3D printing is excellent in short-term follow up,achieving good reduction with limited trauma,long-term prognosis needs to be further followed up.

Objective To investigate the dynamics of white blood cell count (WBC),prealbumin(PA),high sensitive C-reactive protein (hs-CRP),and vascular endothelial growth factor (VEGF) in hand-foot-and-mouth disease (HFMD) complicated with or without encephalitis and in vitro inhibitory effects of artesunate on VEGF secretion of mononuclear cells from HFMD patients.Methods Peripheral blood mononuclear cells from healthy control group,HFMD group and HFMD combined with encephalitis group were isolated by Ficoll density gradient centrifugation and treated with different concentrations of artesunate (25,50,100 mg/L).The expression of VEGF in the supernatant was examined by ELISA double antibody sandwich method.The levels of WBC,PA and hs-CRP in the three groups were also detected.Multiple samples were compared by one-way analysis of variance.Multiple comparison was performed by Dunnett T3 test.Correlation of two variables was analyzed by Spearman correlation test.Results There were significant differences in the levels of WBC,hs-CRP,PA and VEGF between the HFMD combined with or without encephalitis group and health control group (F=172.69,366.02,166.32 and 5 941.89,respectively,all P＜0.01).There were significant differences in the levels of VEGF secreted by mononuclear cells treated with three different concentrations of artesunate between the HFMD combined with or without encephalitis groups and health control group (F =194.265 and 4 750.69,respectively,both P＜0.01).Correlation analysis showed that the VEGF level secretion by mononuclear cells from HFMD patients with or without encephalitis were both negatively correlated with different concentrations of artesunate (r=-0.903 and-0.969,both P＜0.01).Conclusions Compared with HFMD without encephalitis,the secretion of VEGF by mononuclear cells,WBC and hs-CRP levels in HFMD complicated with encephalitis group all increase and PA decrease significantly.Artesunate can inhibit the secretion of VEGF by mononuclear cells of patients with hand-foot-and-mouth disease in a dosedependent manner in vitro.
