Objective To Compare postoperative complications between patients with varicose veins of the lower limbs treated with foam sclerotherapy or endovenous laser.Method From 2011 to 2015,simple varicosis of great saphenous vein patients (grade C3-6) in 2 542 cases,3 468 limbs were divided into 2 groups.Combined with high ligation of great saphenous vein plus stripping,foam sclerotherapy group (1 355 cases) underwent calf foam sclerotherapy (1％ polidocanol),endovenous laser group (1 187 cases) underwent endovenous laser therapy.All postoperative patients were treated with stretch socks for 3 months.Postoperative pain (calf),deep vein thrombosis,pulmonary embolism,superficial thrombophlebitis,saphenous nerve injury,ecchymoma,migraine,allergic dermatitis,pigmentation in 2 groups were compared.Result During the follow-up,28 cases in foam sclerotherapy group had saphenous nerve injury (2％),1 071 (79.1％) cases had subcutaneous ecchymosis,613 cases (51.6％) in endovenous laser group had saphenous nerve injury,979 cases (82.5％) had subcutaneous ecchymosis,8 cases (1.0％) had skin burns (x2 =824.660,4.786,9.161,P ＜ 0.05).Endovenous laser group (23.8％) was significantly better than that of foam sclerotherapy group (30.8％) in pigmentation (x2 =15.243,P ＜0.05).Conclusion Treatment of varicose veins of the lower leg with foam sclerotherapy has less postoperative complications compared with endovenous laser.

Objective To investigate the clinical value of circulating miR-125b-5p in coronary atherosclerotic heart disease.Methods With case-control study,80 cases of coronary atherosclerotic heart disease were recruited in Affiliated Hospital of Nantong University from February 2014 to august 2015.According to coronary angiography result they were divided into two groups: there are coronary artery stenosis group(n=49)and control group(n=31).All patients were also divided into non-ST-segment elevation myocardial infarction and ST-segment elevation myocardial infarction group(n=35),unstable angina group group(n=25),stable angina group(n=20).The level of miR-125b-5p before coronary angiograph was detected.By independent sample t test and variance analysis,the levels of miR-125b-5p were compared between the groups of coronary artery stenosis and the group with no stenosis of the coronary artery,the coronary artery lesions in each group,and between the various types of coronary atherosclerotic heart disease respectively.Results MiR-125b-5p expression level of Coronary artery stenosis group(0.35±0.10)was lower than that in group coronary artery with no stenosis(0.95±0.12),the difference was statistically significant(t=24.179,P<0.000 1).With the increase in the number of diseased coronary arteries,miR-125b-5p expression level decreased gradually.There is also statistical significance(t=8.399,P<0.000 1; t=13.067,P<0.000 1)in miR-125b-5p expression among NSTEMI+STEMI,UA and SAP groups.miR-125b-5p expression level was negatively correlated with Gensini score(R2=0.822,P<0.05).The area under the ROC curve(AUC)of miR-125b-5p was 0.86(95％CI 0.67-0.90),and 0.66 was the optimal cut-off value with sensitivity of 81.22％and specificity of 78.62％.Conclusions With the increase of the number of stenosis,plasma miR-125b-5p expression level decreased gradually.The expression level of miR-125b-5p was negatively correlated with the Gensini score of coronary artery,which indicated that the expression level of miR-125b-5p may be a potential biomarker that can reflect the lesion degree of coronary artery.

The total knee replacement is an excellent method for the treatment of osteoarthritis, rheumatoid arthritis, etc. of the knee joint. The tendency of the use of total knee prosthesis is increasing now in Korea. But domestic production of the prosthesis is not avaliable and all are imported from abroad. Moreover, these prosthesis are not well adapted to Korean people, and in occation, the custom-made prosthesis should be needed. So, domestic production of the prosthesis is required. For production of new prosthesis, in cooperation with KAIST(Korea Advanced Institute of Science and Technology), we developed the new alloy 15-57 for total knee prosthesis. We conducted an animal experimental study to confirm the biocompatibility of the new alloy. In this experiment, the Zimmer® company vitallium was compared with this new alloy as control study. The results are as follows: 1. Biocompatibility of the new alloy 15-57 is similar than that of Zimmer® company vitallium in histological study of metal-bone interspace area. 2. Surface corrosion of both metal was nearly absent. 3. In summary, the new alloy 15-57 is suggested as an acceptable metal for the production of total knee prosthesis.

OBJECTIVETo explore the effect of electro-acupuncture to improve the bladder function after acute spinal cord injury in rats and its possible mechanism.

METHODSSixty healthy adult male SD rats of SPF grade, with body weight of 220 to 250 g, one week after feeding adaptation, were randomly divided into sham operation group, model group, electro-acupuncture group, electro-acupuncture control group with 15 rats in each group. Sham operation group underwent no stimulation, and the moderate damage model of spinal cord injury were made in other three groups according to modified Allens method. The model group were not treated, electro-acupuncture group were treated with electro-acupuncture on Zhibianxue and Shuidaoxue, and electro-acupuncture control group were treated with electro-acupuncture on 0.5 inch next to Zhibianxue and Shuidaoxue. The frequency of 2/100 Hz, current of 1 mA, stimulation time of 15 min, once a day, left and right alternately stimulate every time, for a total of 7 times. The changes of residual urine volume and urine output in rats at the 1st and the 7th days after operation were observed. And 7 d later, the rats were sacrificed and the injured spinal cord were taken out to observe the apoptosis, and to detect the changes of Bcl-2, Bax, Bad content.

RESULTSAfter modeling,the rats of three groups showed different bladder dysfunction. In electro-acupuncture group and electro-acupuncture control group, the residual urine volume of the 7th day after operation was significant lower than the 1st day after operation (P < 0.001), and there was statistically significant difference on the 7th day after operation between two groups (P < 0.001). Compared with model group, the urine output of electro-acupuncture group and electro-acupuncture control group was significantly increased on the 7th day after operation, and there was sig- nificant difference between electro-acupuncture group and electro-acupuncture control group (P < 0.001). Electro-acupuncture can inhibit apoptosis of spinal cord neurons by TUNEL detection. Postoperative at 7 d, the rate of nerve cell apoptosis in electro -acupuncture group and electro-acupuncture control group was significant increased than model group (P < 0.01, P < 0.05), and there was significant difference between electro-acupuncture group and electro-acupuncture control group (P < 0.005). Compared with model group, the positive expression rate of Bax, Bad decreased (P < 0.01, P < 0.05), and Bcl-2 increased (P < 0.01) in electro-acupuncture group and electro-acupuncture control group,there was significant difference between electro-acupuncture group and electro-acupuncture control group (P < 0.01).

CONCLUSIONElectro-acupuncture can obviously promote the repair of acute spinal cord injury,its mechanism may be through increasing Bcl-2, inhibiting the expression of Bax, Bad, which inhibits the apoptosis of spinal cord neurons.

This article made a brief analysis of clinical adverse effects of cinnabar. Except for allergic reaction, almost all the adverse events of cinnabar were caused by unreasonable application. The majority of the poisoning cases were associated with excessive and/or long-term dosage, and improper preparation methods, such as decocting, heating or fumigating. Children showed to be prone to poisoning. The poisoning caused by unreasonable use of cinnabar should be considered to be drug alert, but not advert effect. And the toxicity of cinnabar could be avoided by normalizing the preparation method, controlling the dosage and duration.
