Objective To investigate the efficacy of Ginkgo‐Leaf Capsule combined with tripterygium glycoside in the treat‐ment of diabetic nephropathy(DN) and its influence on CysC ,Hcy and VEGF .Methods Eighty patients with DN treated in our hospital from January 2013 to April 2015 were selected as research subjects and equally divided into the control group and the ob‐servation group according to the random number table ,40 cases in each group .Besides the conventional Western medicine treat‐ment ,the control group was given tripterygium glycoside ,while the observation group was given Kinkgo‐Leaf Capsule combined with tripterygium glycoside .The treatment course was 3 months .Then ,the curative efficacy ,indices of renal function ,levels of Cy‐sC ,Hcy and vascular endothelial growth factor(VEGF) ,and occurrence situation of adverse reactions were compared between the two groups .Results The total therapeutic efficacy rate in the observation group and the control group was 92 .50% and 80 .00%respectively without statistically significant difference (P>0 .05) .In the comparison with the control group after treatment ,the re‐nal function indices of serum creatinine ,urea nitrogen ,24 h urinary protein ,level of serum CysC ,Hcy and VEGF in the observation group were statistically decreased (P< 0 .05) .During the treatment process ,no severe adverse reactions occurred in the two groups .The incidence rate of adverse reactions in the observation group and the control group was 17 .5% and 12 .5% respectively without statistical difference (P>0 .05) .Conclusion Ginkgo‐Leaf Capsule combined with tripterygium glycoside is effective and reliable for treating DN ,which can significantly improve the renal function ,reduces the level of serum CysC ,Hcy and VEGF .

[Objective] To investigate the causes of failures of long bone fractures with internal fixations and to study the treatments and effects of reoperations of long bone fractures with inter-locking intramedullary nail and limited open reduction.[Method]Twenty-four patients of failures of long bone fractures with internal fixations were retreated with inter-locking intramedullary nail and limited open reduction.There were 15 cases of femoral fracture,7 cases of tibial fracture and 2 cases of humerus shaft fracture.Of the femoral fracture,there were 14 cases of fractures of shafts of femurs and 1 case of supracondylar fracture of femur;11 male,4 female;7 left cases,8 right cases;1 case complicated with bending of bone plate and screw,6 cases with breakages of plate;1 case with bending of common intramedullary nail,2 cases with breakages of common intramedullary nails,1 case of screw and wire lock fixation complicated with pseudoarticulation formation,4 cases with nonunion of fracture.Of the cases of tibial shaft fracture,there were 6 male,l female;3 left cases,4 righe cases;3 cases complicated with breakages of bone plate and screw,1 case with failure of external fixator,3 cases with nonunion of fracture.Of the cases of humerus shaft fracture,there were 2 cases of male and left ones;1 case complicated with breakage of bone plate and screw,1 case with breakage of common intramedullary nail.The ages of patients ranged from 18 to 68 years old with mean ages 43.7 years old.All fixation failure cases were retreated with inter-locking intramedullary nails and limited open reductions with autogenous iliac bone grafts or bone allografts.[Result]The average follow-up time was 25 months(12～35 months).All cases were cured with bone unions.Complications with submerge,breakages and bending of intramedullary nails did not occur.In the reoperating cases of femoral and filial fractures,the knee function were excellent in 18 cases,good 2 cases,fair 1 case and poor 1 case according to Karlstrom scale.Among the reoperating cases of humeral fractures,there were 1 case excellent and 1 good of shoulder function according to HAN score.[Conclusion]Reoperations with inter-locking intramedullary nail and limited open reduction are effective methods for treatment of internal fixation failure of long bone fracture.

Objective　To study the changes of the four active substances endothelin(ET),calcitonin gene related peptide (CGRP),thromboxane B2(TXB2) and 6-Keto-prostaglandin F1α(6-Keto-PGF1α) in plasma when they acted on each other in the formation and development of diabetic retinopathy.Methods　Using the method of radio-immunity,the levels of ET,CGRP,TXB2,6-Keto-PGF1α in plasma were measured in four groups of patients with type 2 diabetes (group 1∶40 cases without retinopathy;group 2∶40 cases with primary retinopathy;group 3.40 cases with hyperplasia type of retinopath;group 4∶40 cases normal controls).Results　The results showed that ET increased progressively (P＜0.01) with the prolonging of the duration of DM and the worsening of retina damage、CGRP showed a decreasing tendency (P＜0.05,P＜0.01) in the advanced stage of DM retinopathy.Rectilinear regression analysis showed that the association of ET/CGRP with TXB2/6-Keto-PGF1α became closer with the worsening of deabetic retinopathy (r=0.44,P＜0.05;r=0.596,P＜0.01).Conclusion　The four active substances acted on each other in the formation and development of diabetic retinopathy.It had a significent meaning in the initial mechanism of DM,in the development of disease and in the direction of medication usage to understand their relationship.

Objective To evaluate the tumor dose distribution of routine radiotherapy plan in esophageal cancer with 3D treatment planning system. Methods For the 19 esophageal cancer patients who were diagnosed, the thoracic CT were done and GTV, CTV and PTV were delineated on the image of CT. Then a routine 3 field radiotherapy planning was produced using the Cad Plan 6.4.7 treatment planning system. The dosimetric results of GTV, CTV and PTV, target conformity and the dosimetric uniformity of variant target volume gained from DVH were compared. Results The maximal dose of GTV, CTV and PTV was 51.64Gy, 51.94Gy, 51.48Gy, respectively; the minimal dose was 41.17 Gy, 25.31 Gy, 18.94 Gy, respectively; the mean dose was 49.5 Gy, 47.34 Gy, 42.92 Gy, respectively; the conformity index was 0.94, 0.69, 0.38, respectively; and the dose variability was 2.2 Gy, 7.57 Gy, 14.56 Gy. Conclusions The routine radiotherapy plan in esophageal cancer could not offer satisfactory dose distribution. The method of CT simulation and 3D treatment planning systems should be applied to decide treatment planning.

Protein ubiquitin-like modification of Neddylation is an important post-translational modification mode of protein to widely regulate cell cycle, growth, development and other biological processes. Recent studies have found that MLN4924, small molecule inhibitor of Neddylation modification, has a significant anti-tumor effect, which can inhibit the tumor growth by inducing cell cycle arrest, senescence and apoptosis, and inhibiting tumor angiogenesis. This paper reviews the related mechanism research of cell programmed death induced by Neddylation modification pathway inhibitor MLN4924.

Objective To understand pathogen spectrum of bacterial and fungal infection of central nervous system (CNS),and evaluate the etiological diagnostic value of universal primer polymerase chain reaction (PCR).Methods Data about patients with suspected or confirmed bacterial and fungal infection of CNS from January 2009 to March 2015 were collected,species of pathogens from cerebrospinal fluid (CSF)were analyzed,DNA from patients’CSF were performed PCR amplification and sequencing with universal primers of bacterial 16S rRNA and fungal 28S rRNA, PCR detection results were compared with CSF culture during the same period.Results A total of 400 patients were with confirmed or suspected bacterial or fungal infection of CNS,132 of whom were with positive CSF culture.150 pathogenic isolates were detected,including 48 isolates of gram-positive bacteria,90 gram-negative bacteria,and 12 fungi;the top three isolated bacteria were Acinetobacter baumannii (n =32 ),coagulase negative staphylococcus (n=16)and Klebsiella pneumoniae (n=13);the most common fungus was Cryptococcus neoformans (n=8).CSF from 88 infected patients and 20 non-infected patients were selected for PCR amplification,the sensitive of PCR am-plification assay was higher than the culture method (35.23% [31/88]vs 28.41 %[25/88],χ2 =4.17,P <0.05).
