ABSTRACT
Objective To explore the application value of closed negative pressure drainage technique in wound healing of hand trauma.Methods From August 2013 to October 2017,80 patients with hand trauma in the Traditional Chinese Medicine Hospital of Cixi were divided into two groups according to the random principle,with 40 cases in each group.The control group was treated with conventional wound repair,and the observation group was treated with closed negative pressure drainage.The repair effect,healing,secondary operation,antibiotic use,hospitalization,histopathological score and patients'satisfaction were observed.Results The total effective rate of the observation group (97.50％) was obviously higher than that of the comrol group(80.00％) (x2 =6.13,P ＜ 0.05).The time of healing,length of hospital stay and the use time of antimicrobial agents in the observation group were (15.11 ±2.43) d,(16.27 ± 1.79) d and (6.06 ± 0.65) d,respectively,which were all lower than those in the control group (t =14.43,13.31,23.29,all P ＜ 0.05).The second operation rate of the observation group (5.00％) was lower than that of the control group(P ＜ 0.05),and the histopathological score in the observation group (7.11 ± 0.53) was higher than that in the control group (P ＜ 0.05).The satisfaction rate of the observation group (100.00％) was obviously higher than that of the control group(x2 =6.49,P ＜ 0.05).Conclusion In the treatment of wound healing of hand trauma,the application of closed negative pressure drainage technology is better,which can effectively control the disease and is worthy of further promotion and use.

ABSTRACT
Objective To evaluate the image quality improvement on abdominal CT imaging by using new model-based iterative reconstruction (MBIRn)in comparison with adaptive statistical iterative reconstruction (ASiR).Methods 40 patients who underwent upper abdominal three-phase contrast-enhanced scan were included.After scanning,all the scans obtained at 180 s later injection were reconstructed by three protocol,including ASiR (combined reconstruction of 40%FBP and 60%ASiR),the MBIRn of the noise reduction settings (MBIRNR40)and the spatinal resolution settings(MBIRSTND).The thickness of the slice was 0.625 mm.The values of CT and SD of the subcutaneous fat,left erector spinae,inferior vena cava and hepatic vein (left and right branches)were measured at the branch level of hepatic vein,and the contrast noise ratio (CNR)between inferior vena cava and hepatic vein were calculated.The subj ective image quality was evaluated by two radiologists according to the noise,smoothness and small branches of the inferior vena cava and hepatic vein using 5-scoring method.The quality images obtained from ASiR method were treated as reference standard.Results For MBIRSTNDand MBIRNR40images,the subjective noise decreased and image quality increased comparing with ASiR images.Among which the MBIRNR40images had the best image with vascular smoothness score and the lowest subjective noise.Conclusion Compared with ASiR,MBIRSTNDand MBIRNR40,especially MBIRNR40improves the quality of CT images of the inferior vena cava and its branches.

[Objective] Discuss traditional Chinese medicine garden burnet powder embolism treating fibroid's action mechanism.[Methods] Treat 120 patients with line of ultra selective arteria uterina intubation radiography and embolism,observe result after 3~12 months,make a follow-up visit.[Results] Arteria uterina radiography demonstrats fibroid for rich vascular tumor;after TUAE treatment,treatment group 84.31%,control group 83.33%;the patient menstrual volume restores normally gradually;at 2 month reexamination,treatment group 80.95%,control group 77.5%;the patient hemoglobin value achieves the normal level.At follow-up visit,the myoma size of the treatment group is reduced to an average of 73.2%,the control group reduced to 70.1%.[Conclusion] The garden burnet powder involving embolism treating the fibroid has the superiority and the security compared to other material,opening one new way,having the important clinical practice value,worth clinical further consummating and promoting.
