Objective Clinical data of patients who received rotational atherectomy (RA) combined with drug-eluting stent implantation (DES) in TEDA International Cardiovascular Hospital were retrospectively analyzed to evaluate it's safety,short-term and long-term prognosis.Methods A total of 60 patients who underwent RA were consecutively enrolled in the study in TEDA International Cardiovascular Hospital from September 2012 to September 2015.Pre and post procedure coronary angiography and clinical information were collected.Long term outcomes were obtained by outpatient clinical follow-up or telephone interview.We analysed angiographic data.Results Among 60 patients with 65 lesions,RA combined with drug-eluting stent implantation was successful performed in 62(95.3%) lesions and postoperative stenosis degree drop from (90.7±6.2)% to (19.5±6.6)%.4 cases(6.7%)developed complications and were treated accordingly during procedure with satisfactory results.Overall incidence of in-hospital MACCE was 1.7% with one case (1.7%) of myocardial infarction.The mean follow-up time was (23.3±10.6) months.In stent restenosis occurred in 1 case(1.7%) 10 months after operation.Stent thrombosis occurred in 1 case(1.7%) 16 months after operation and myocardial infarction (MI) occurred in 1 case(1.7%) 7 months after operation.One patient died 14 months after operation and another patient died 17 months after operation.Both of them were considered as cardiac death.There was no mortality of other causes recorded.Long-term MACCE was 9.5% and TLR is 5.1%.Conclusions Rotational atherectomy combined with DES implantation in the treatment of severe coronary artery calcification lesions has high success rate, good safety profile and good short and long-term prognosis.

Objective To study the characteristics of pharmacokinetics and pharmacodynamics of insulin dry powder inhalation and its relative bioavailability as compared with subcutaneous injection of regular insulin. Methods In this open,single-center,randomized,two-period,cross-over,euglycemic glucose clamp study,18 healthy volunteers(14 men and 4 women),aged(24.9?1.7)years,with body mass index(20.6?1.2)kg/m~2, received the insulin dry powder inhalatin(80 U)or regular insulin(15 U)subcutaneous administration.The blood samples of this study at 0,20,30,40,50,60,70,80,90,100,110,120,135,150,165,180,195, 210,225,240,270,300,330,360,390,420,450 and 480 rain were taken for serum insulin measurement, meanwhile,glucose infusion rates(GIR)were determined per 5 minutes over a period of 8 hours.Results The C_(max)were(57.9?17.8 vs 114.5?29.7)mU/L(tested vs reference preparation),T_(max)were(46.7?45.6 vs 107.8?33.7)min,GIR_(max)were(3.35?0.98 vs 5.17?1.75)mg?kg~(-1)?min~(-1)and T_(GIRmax)were(88.3?17.0 vs 151.9?34.6)min.The relative bioavailability was(10.26?2.25)%,and the relative bioefficacy was(14.33?7.26)%.Conclusion The study shows that insulin dry powder inhalation is absorbed via lungs and its action sets in earlier than that of the regular insulin injected subcutaneously.These pharmacokinetie and pharmacodynamic data may provide a reliabe guide for further clinical trial.

Objective To investigate the effects of hydrogen sulfide on autophagy and the apoptosis after acute spinal cord injury in rats. Methods Thirty-six adult male SD rats (250-300 g) were randomly divided into three groups (n=12 for each group):sham operation group (Sham group), spinal cord injury group (Model group) and hydrogen sulfide pre-treatment group (H2S group). Allen’s method was used to establish the rat model of spinal cord injury. Rats of sham operation group re?ceived only laminectomy. Rats of H2S group received sodium hydrosulphide injection intraperitoneally (50μmol/kg) 1h after spinal cord injury, and Model group was given the same amount of saline solution. Rats in the three groups were sacrificed 24 h after spinal cord injury, then the spinal cord was removed. The expressions of LC3, p70S6K and Cleaved caspase-3 were detected by Western blot assay. The expression of LC3 was also detected by immunofluorescence. The cell apoptosis was as?sessed by TUNEL stain. Results Compared with Sham group, the expression levels of LC3Ⅱ/LC3Ⅰand Cleaved caspase-3 were increased in Model group, but the expression of p70S6K decreased and cell apoptosis increased in Model group (P<0.01). Compared with Model group, the expression levels of LC3Ⅱ/LC3Ⅰand Cleaved caspase-3 were decreased significant?ly, while the expression of p70S6K increased and cell apoptosis decreased significantly in H2S group (P < 0.01). Conclu?sion Hydrogen sulfide can inhibit autophagy and reduce cell apoptosis after acute spinal cord injury in rats.

AIM: To explore the localization and expression of transfo rming grow th factor-? 1,2 (TGF-? 1,2 ) and alpha-smooth muscle actin (?- ASMA) in fetal a nd adult skins. METHODS: Skins of 15 cases of fetuses with different gestational ages and 5 cases of adults were taken, embedded with paraffin wax, and sectione d. Immunohistochemistry method and pathological method were used to detect the e xpression intensity and distribution of TGF-? 1,2 and ?-ASMA. RESULTS: Positive immunohistochemical signals of TGF-? 1,2 and ?-A SMA were found in fetal and adult skins. In skins derived from young fet us, the positive signals of these three proteins were very weak. Along with the incr ement in gestational age, the positive cellular rates of TGF-? 1,2 and ?- ASMA were elevated pro gressively. In elder fetal and adult skins, TGF-? 1,2 were mostly distributed i n epidermal cells, endothelial cells and some fibroblasts, while ?-ASMA was mainly located in myofibroblasts and sweat gland epithelial cells. CONCLUSION: The endo genous TGF-? 1,2 might be involved in the cutaneous development at embryoni c stage, in the cutaneous structure maintenance at adult stage, and in the wound healing af ter injury.

Advanced gastric cancer is usually dealt with D2 radical dissection. There are different opinions as to whether it is necessary to perform D3 radical lymphadenectomy.Some scholars thought that properly enlarged radical dissection can improve long-term outcomes for the treatment of advanced gastric cancer.In recent years,laparoscopic D1 and D2 radical dissection of gastric cancer could be carried out in many hospitals.However,the technique and related skills for performing D3 radical lymphadeneetomy through laparoscope remains to be explored.Based on our previous experiences,D3 radical lymphadeneetomy using artery suspension method and medial-to-lateral approach for advanced gastric cancer is proved to be safe and feasihle.

Objective To evaluate the effectiveness of the current measure of Oncomelania hupensis control in Jiangsu Province. Methods The snail control was carried out with molluscicides in the high transmission areas every year. Some snail habitat areas were modified. The snail areas within three years were re-treated with molluscicides in the maintenance phase. The snail survey was carried out every spring, and the data were analysed with SAS software. Results From 1995 to 2001, 14519.17 hm 2 of snail habitats were molluscicided, 2768.57 hm 2 were modified, and 8803.64 hm 2 were re-treated with molluscicides in the maintenance phase. The coverage rates of snail control areas dropped by 19.14% every year. The snail areas increased by 6.25% every year from 1995 to 2002. In which, the areas of infected snails increased by 18.52% every year. The correlation analysis showed that the areas of infected snails increased with the increasing of the total snail areas. At the same time, the areas of infected snails increased with the fall of the coverage rates of snail control areas. The analysis of the snail distribution showed that the main problem was poor snail control. Conclusion In recent years, the rise of area of snail habitats is serious in Jiangsu Province. The present measures of the snail control have not effectively stopped the spreading and increasing of snails. The research on the new molluscicides, the new methods of snail control and the better policies are very important.

Objective To assess the clinical and radiologic outcomes between laminoplasty with forominotomy(LF) and anterior cervical discectomy and fusion(ACDF) in treating cervical radiculomyelopathy(CRM). Methods Datas of 68 patients (ACDF=33, LF=35) from January 2008 to January 2010 was collected retrospectively, the follow-up is at least 2 years. The Japa-nese Orthopedic Association (JOA) score and associated recovery rate were evaluated. For radiographic evaluation, the lordotic an-gle and range of motion (ROM) at C2-C7 were investigated. The Neck Disabilitv Index Scale(NDI) was used to evaluate the degree of patient’pain at the last follow-up. Results Patients’demographics were similar between the two groups. The differences be-tween ACDF and LF in operative time (187min VS 154min),the blood loss (127 ml VS 235 ml) and the sensation of lower extremity (64.0%VS 66.0%) are significant(t=4.170, P=0.000;Z=-6.888, P=0.000;Z=-7.512, P=0.000). 1 case with failed fusion of bone graft 3 months post-operation. 3 cases of adjacent segment degenerative changes occurred at the 2nd year follow-up in ACDF group. But no such complications occurred in the EOLF group. In addition, ACDF group showed lower NDI score than LF group in extracting and amusing (Z=-3.947, P=0.000;t=-7. 523, P=0.000). Cervical lordosis of ACDF increased from 13.7° to 16.2°, while that of LF group decreased from 14.6° to 13.3°(Z=-3.374,P=0.001);Both of the two groups (ACDF/LF) exhibited decreased cervi-cal ROM (14.8° VS 16.5°, t=-2.167, P=0.034). Conclusion The two surgical procedures have similar clinical effects in treating multi-segmental CRM. However, the LF group demonstrated shorter operative time, fewer short-term complications, so it proved to be effective and safe surgical procedure.
