Objective To observe the efficacy of anatomical locking plate combined with anchor nail internal fixation and clavicular hook plate in the treatment of Neer Ⅱ distal clavicle fracture and their impact on shoulder function.Methods Eighty patients with Neer Ⅱ distal clavicular fracture treated in the Eighth People's Hospital in Shanghai from January 2015 to December 2016 were divided into observation group and control group,each group 40 cases.The observation group was treated with anatomical locking plate combined with anchor nail,the control group was treated with clavicular hook plate.The efficacy,operation time,intraoperative blood loss,fracture healing time,postoperative hospital stay,shoulder function score and incidence of complication were observed in the two groups.Results The excellent rate was in the observation group was higher than that in the control group (97.50%(39/40) vs.80.00%(31/40),χ2=2.477,P<0.01).The operation time,intraoperative blood loss and postoperative hospital stay in the observation group and the control group were (53.36±4.69) min vs.(54.19±5.13) min,(69.65±7.17) ml vs.(70.38±8.29) ml,(7.39±1.64) d vs.(7.42±1.97) d,the differences between the two groups had no statistical significance (P>0.05);the fracture healing time in the observation group was longer than that of the control group ((23.65±2.19) w vs.(26.9±3.46) w,P<0.01).The shoulder joint Constant-Murley score in the observation group was (86.02±5.19) points,control group (68.46± 6.94) points,the difference was statistically significant (P<0.01).Observation group showed 2 cases of pain around acromion,the incidence rate of complications was 5.00%(2/40);7 cases in the control group had pain around acromion,2 cases suffered from impingement syndrome and 1 cases had delayed union,the incidence rate of complications was 25.00% (10/40).Conclusion Anatomical locking plate combined with anchor nail internal fixation is effective in the treatment of Neer II distal clavicle fracture.It has the advantages of fast fracture healing,good functional recovery of shoulder joint and less complications.

Myelodysplastic syndromes (MDS) are a heterogenous group of hematologic malignancies characterized by clonal expansion of BM myeloid cells with impaired differentiation. Of particular interest mutations is the recent recognition that genes involved in the regulation of histone function (EZH2, ASXL1,and UTX) and DNA methylation (DNMT3A,IDH 1/IDH2,TET2) are recurrently mutated in MDS,providing an important link between genetic and epigenetic alterations in this disease. Ongoing analysis of the seminal AZA-001study has taught many important lessons in the use of DNA methyltransferase (DNMT) inhibitors.Improved survival in patients with high-risk MDS treated with azacitidine extends to patients with any International Working Group-defined hematologic response.New information on the impact of DNMT inhibitors on the immune system and on stem cells will likely lead to novel uses of these drugs in MDS and other hematologic and nonhematologic malignancies. The immunomodulating drug thalidomide and its derivative lenalidomide have been used in the treatment of MDS,principally in lower-risk MDS.

OBJECTIVE: To study the effect of MDR1 (P-gp) and ABCG2 on the drug resistance in Hep 2 cells. METHOD: Flow cytometry was used to detect the variations of the antitumor drugs accumulation and discharging, and activity variations when MDR1 and ABCG2 inhibitors were used in Hep-2. RESULT: The accumulation and discharging of mitoxantrone was significantly higher than the control group when ABCG2 inhibitor FTC was used in Hep-2 (P<0. 05). In contrast, P-gp did not appear similar case; To the mitoxantrone and cisplatin, there was no statistical correlation about activity of Hep-2 between P-gp or ABCG2 antagonist and the control; To the doxorubicin, combining FTC and P-gp, the activity of Hep-2 was higher than the control and difference was significant (P<. 05), In contrast, FTC and P-gp did not appear similar case when used alone; To the 5-FU, when PGP used, the activity of Hep-2 was higher than that in the control and difference was significant (P<0. 05), In con- trast, FTC and FTC+P-gp did not appear similar case; To the paclitaxel, when P-gp or FTC+P-gp used, the activity of Hep-2 was higher than that in the control and difference was significant(P<0. 05). CONCLUSION ABCG2 may lead to drug resistance mainly by changing the ability of cell in accumulating and discharging chemotherapy drugs. P-gp has other way. P-gp and ABCG2 play different roles in different drug resistance.

Objective To compare the difference among DNA damages in physics processes caused by protons with different energies around Bragg peak.Methods By constructing the nucleus and DNA model using Geant4 and simulating the transportation processes of protons with different energies around Bragg peak in nucleus model based on Geant4-DNA,the information of interaction points were recorded.16％ of them were picked randomly to use as the points at which protons interact with DNA.After finding out the points which broke the DNA and writing their information to new files,these new files were treated with density-based spatial clustering of applications with noise (DBSCAN),so as to analyze and calculate the difference of DNA damages caused by protons with different energies.Results With the protons with energies from 20.0 to 0.6 MeV,the numbers of damage points and damage clusters increased from 49.86 to 549.88 and from 2.92 to 82.46,respectively;the numbers of clusters with different sizes had a remarkable increase,and the number of clusters with size not less than 5 increased by 400 times.The average cluster size increased slightly.Simple single strand breaks (SSSBs),complex single strand breaks (CSSBs),simple double strand breaks (SDSBs) and complex double strand breaks (CDSBs) of DNA increased by about 8,26,24 and 64 times,respectively.The proportion of single strand breaks (SSBs) decreased from 96.69％ to 89.37％,and the double strand breaks (DSBs) increased from 3.31％ to 10.63％.Conclusions The lower proton energy would result in the more complex damage to DNA and the harder repair of DNA damage.
