Objective To explore the analgesic effect of ropivacaine and flurbiprofen for patients with secondary upper extremity lymphedema after lymphatic venous anastomosis . Methods A total of 45 cases of lymphatic venous anastomosis under general anesthesia between October 2014 and March 2016 were randomly allocated to 3 groups: ropivacaine group ( group R ) , flurbiprofen preprocessing group (group F1), and flurbiprofen postprocessing group (group F2), with 15 cases in each group.Local infiltration anesthesia was made with 0.2% ropivacaine 10 ml at the incision before the end of operation in the group R .The flurbiprofen 100 mg was intravenously injected at 5 minutes before the induction of anaesthesia in the group F 1 and 5 minutes before the end of operation in the group F 2 .The visual analogue scale ( VAS) scores and the number of patients using analgesics after operation at 1, 2, 6, 12, 24 and 48 h were recorded. Results The rest pain and movement pain VAS scores at postoperative 2 h were lower in the group R than those in the group F1 and F2[rest pain:(3.4 ±0.7) points vs.(4.2 ±0.9) points vs.(4.1 ±1.0) points, F=3.741, P=0.032;movement pain:(3.7 ±0.6) points vs.(4.6 ±0.9) points vs.(4.4 ±1.0) points, F=4.305, P=0.020]. The rest pain VAS scores at postoperative 6 h were lower in the group R than those in the group F 1 and F2 [(2.7 ±0.5) points vs. (3.4 ±0.5) points vs.(3.1 ±0.6) points, F=5.783, P=0.006].The number of patients requiring analgetics was lower in the group R than that in the group F1 and F2 at postoperative 2 h (1 case vs.7 cases vs.5 cases,χ2 =6.058, P=0.048). Conclusion Local anesthesia with ropivacaine in patients after lymphatic venous anastomosis can achieve good postoperative analgesia .

Objective: To evaluate the success rate and potency rate of functional and traditional end-to-side anastomosis for radial artery-cephalic vein arteriovenous fistula in hemodialysis patients, so as to summarize our experience and to improve the operation outcomes. Methods: Totally 124 patients with chronic renal failure receiving radial artery-cephalic vein arteriovenous shunt for hemodialysis were randomly divided into 2 groups, namely, the functional end-side anastomosis and the traditional end-side anastomosis. The successful rate and year patency rate of the two methods were compared and analyzed. Results: The mean operation time periods for functional and traditional end-side anastomosis were (20.4±5.6) min and (26.2±5.2) min, respectively(P<0.05). The 1-month, 6-month, and 12-month patency rates were 93.6%, 87.3%, and 76.2%, in the functional end-side anastomosis group, and 95.1% (P>0.05), 82.0%(P>0.05), 72.1%(P>0.05) in the traditional end-side anastomosis group, respectively, with no significant differences found in the three rates between the two groups. Conclusion: The short-term and long-term patency rates are similar between hemodialysis patients undergoing functional and traditional end-to-side anastomosis for radial artery-cephalic vein arteriovenous fistula. The functional end-side anastomosis is more convenient and needs a shorter time, and it also makes it easy for a second surgical exploration.

When adult developmental dysplasia of hip (DDH) patients have developed secondary os- teoarthritis of hip (OAH) with serious clinical symptoms,total hip replacement (THR) is their first choice of treatment.The anatomic structures of the acetabulum and femur in these patients are ahnormal and special,such as small and shallow cup,small femoral head,and narrow medullary cavity at proximal femoral shaft.As a result,the THR for DDH patients is quite different from the conventional ones and is thus highly difficult.We review in this paper the clinical classification of DDH,which is important for its treatment,the difficulties we will have in THR, especially in acetabular reconstruction and femoral prosthesis placement,and also strategies to resolve them.

Objective To explore the diagnostic value of the quantitative detection of miRNA-145 and miRNA-143 in the ser-um of children with Kawasaki disease (KD).Methods In this study,45 KD cases were enrolled and were divided into 19 ca-ses with coronary artery lesions (CAL group)and 26 cases without coronary artery lesions (NCAL group).Thirty healthy children were recruited as the control group (NC group).qRT-PCR was conducted to detect the expression of miRNA-145 and miRNA-143 in serum of each group.The diagnostic value of miRNA-145 and miRNA-143 were evaluated by receiver op-erating characteristic curves (ROC)and the area under the curve (AUC)(95%CI).Results The relative expressions of miRNA-145 and miRNA-143 in the serum of the CAL group in acute phase were 2.33±1.26 and 1.64±0.50,which were respectively higher than the control group,with statistically significant difference (t=5.108,5.072,P<0.01).The relative expression of miRNA-145 during the recovery phase of CAL group was 1.55±0.49,which was statistically significant high-er than NC group (t=3.837,P<0.01).While the relative expression of miRNA-143 during the recovery phase of CAL group was 1.17±0.33 and had no difference with NC group (t=1.033,P>0.05).During the acute phase of NCAL group, the relative expressions of miRNA-145 and miRNA-143 were 2.02±1.00 and 1.63±0.50 respectively.They were signifi-cantly higher than the control group (t=4.746,5.261,P<0.01).However,when comes to the recovery phase,the relative expression of miRNA-145 and miRNA-143 were 1.07±0.18 and 1.12±0.16,which had no difference with NC group (t=0.264 9,0.584 9,P>0.05).The critical value of miRNA-145 for diagnosis of KD was 1.697 with sensitivity of 64.44% and specificity of 90% and yielded an area under the curve of ROC of 0.7733 (95%CI:0.667 0~0.879 7).Also,the critical val-ue of miRNA-143 was 1.361 with sensitivity of 64.44% and specificity of 86.67% and yielded an area under the curve of ROC of 0.8163 (95%CI:0.722 5~0.910 0)in discriminating KD from healthy group.Conclusion miRNA-145 and miR-NA-143 may prove to be a non-invasive biomarker for the auxiliary diagnosis of KD.

Objective To investigate the degree of retinal development in preterm infants. Methods Flash electroretinography (ERG) was performed on 25 healthy preterm infants and 25 full-term ones, and the response of rod cells and cone cells and maximal mixed responses were recorded. The delitescence and amplitudes of a- and b-waves and the ratio of amplitudes of b-/a-wave of maximal responses were analyzed. Results Compared with the full-term infants, The delitescence of responses of rod cells in preterm infants was statistically longer (.t=11.007,P.=0.000) but without any significant changes of amplitudes (.t=1.836,P.=0.069); statistically longer delitescence (.t=2.44, P=0.010; (t=10.800,)P.=0.000) and lower amplitude (.t=5.804,P=0.000; t=5.809,P.=0.000) of a- and b-wave of maximal response were found in preterm infants group. In the response of cone cells, there were significant differences of the delitescence (.t=4.444,P.=0.000) and amplitude (.t=3.819,P.=0.000)of a-wave and delitescence of b-wave(.t=2.850,P.=0.005) between the two groups, and no statistical difference of amplitude of b-wave (.t=0.486,P.=0.628) between the two groups. The ratio of amplitudes of b-/a-wave of the maximal mixed response was not significantly different between the two groups ((.t=1.142,)P.=0.256). Conclusions The development of retinal function is slower in preterm infants than that in full-term ones.

Purpose:To study the feasibility of 1 H-magnetic resonance spectroscopy ( 1 H-MRS) in the chemical induced rat hepatocellular carcinoma(HCC) model by a new 1.5T MR set and endeavor to have an initial understanding of the characteristics of its cancer development. Methods:Diethylnitrosamine (DEN) induced rat HCC models(n=30) were established. At different intervals rats were randomly scanned before being killed on the following day. Their livers were dissected for histopathologic study. Results:Three rats died unexpectedly. 27 rats (90%) developed liver lesions and were investigated according to the plan. T 1 WI is good for demonstration of anatomic structure and T 2 WI at showing the lesions in detail. The scanning methods have been improved gradually. 1 H-MRS results were satisfactory for 64% of the single-voxel and 50% of the multi-voxel respectively. Conclusions:DEN induced rat HCC model is suitable for the Medical Imaging studies and liver 1 H-MRS scan is practical with this new 1.5T unit.

Objective To determine the value and limitation of water enema spiral CT (WESCT) in staging of colorectal carcinoma.Methods Forty-eight patients with histologically proven rectum or colon carcinoma were included in this study. All of them were examined by SCT ,and the preoperative staging of TNM and Duke were used based on the findings of SCT.The results of WESCT were compared with those of surgical and pathological examination in all cases. Results All lesions in the 47 cases were demonstrated clearly by WESCT and the sensitivity was 97.9% ; 39 cases of 48 patients were correctly staged with TNM and 42 cases with Duke , the accuracy was 81.3% and 87.5% respectively, which were higher than the overall 50 % accuracy reported by references ;⑶The accuracy of WESCT was 89.6% (43/48) in T stage and 81.3% (39/48) in N stage. Three casas in M stage were all diagnosed correctly;Conclusion WESCT scan is a better method of depicting the colorectal carcinoma. It allows for accurate depiction and staging of colorectal carcinoma, especially detecting the invasion of adjacent tissues and distant metastasis. It is the best imaging method for staging the colorectal carcinoma . However the value of WESCT for early T staging in colorectal carcinoma and minute metastasis of lymph nodes or liver is limited.
