Objective To investigate the clinical application and value of retrograde catheterization via superficial femoral artery for the treatment of limb chronic total occlusive disease (CTO). Methods Fifty-nine patients with proximal and middle occlusive lesions of superficial femoral artery from Jan. 2013 to Jan. 2015 in department of emergency surgery were retrospectively analyzed. Percutaneous transluminal angioplasty (PTA) together with stent implantation was performed to reopen the all narrowed or obstructed superficial femoral artery.Seventeen patients received ipsilateral retrograde catheterization via superficial femoral artery together. The length of the diseased artery ranged from 6.5 to 13.4 cm, with a mean of (8.3 ± 2.9) cm, including right (11 cases)and left (8 cases) femoral arteries. After the interventional therapy patients were followed up for 1- 24 months. Results All patients were treated successfully. The proximal and middle occlusive lesions of superficial femoral artery were reopened.No serious complications were found including nerve and vessel damage+After the treatment, the ischemic symptoms were markedly improved or even disappeared. In 14/19 of patients the superficial femoral arteries remained patent during the follow-up period. The ankle preoperative brachial index (ABI) was 0.20 to 0.51 (0.39 ± 0.06), while the postoperative ABI was 0.65 to 1.15 (0.74 ± 0.13). The difference in ABI between pre-operation and post-operation was statistically significant (P<0.05). Conclusions Retrograde catheterization via superficial femoral artery is an effective alternative to treat proximal and middle occlusion of ipsilateral superficial femoral artery. It has high successful rate and safety.

Subclinical hypothyroidism is common in children,but its clinical significance is widely debated.The pathogenesis is not very clear and etiology appears to be multifactorial,such as autoimmune thyroiditis,obesity,antiepileptic drugs and so on.Currently there is no broad consensus on the management of children with subclinical hypothyroidism.In this review,the available evidences regarding to investigation,risk factors,trreatments and outcomes for this disease are summarized.

Objective:To evaluate the clinical effects of Distal-Jet appliance on the distalization of maxillary molar.Methods:12 Class Ⅱ malocclusion patients(at the average age of 12.3 years) with mesially moved maxillary molar were treated by Distal-Jet appliance. Cephalometic radiographs and dental models were taken and analyzed before and after molar distalization.Results:The treatment time was (4.3?2.8) months. After treatment following effects were achieved:①The maxillary molar was distalized by (3.6?0.75) mm per side with crown tilting distally by ( 3.5 ?3)?. ②The first premolar was moved mesially by (2.1?1.7) mm (tilting movement). Anterior overjet was increased by (1.47?1.76) mm. ③In the vertical dimension,the maxillary molar was extruded slightly by (0.39? 0.46 ) mm, the first premolar was extruded by (0.43?0.61) mm. ④The width between the central point of first maxillary molar was increased by ( 2.8 ?1.1) mm.Conclusions:The Distal-Jet appliance can distalize maxillary molars effectively. However,it may result in distaly tilting of molars and mesial movement of premolars.

Objective To investigate the therapeutic effect of different doses of caffeine on premature apnea.Methods 80 patients with apnea were divided into observation group and control group,each group in 40cases.The two groups applicated caffeine citrate.The control group received the basal dose, first application of 20 mg/kg, intravenous injection, intravenous injection of 5 mg/kg after 24 h.The observation group was treated with intravenous injection of 10 mg/kg after 24 h.The treatment period was 7 d.The therapeutic effect, blood gas and oxygenation index and adverse reactions were observed in the two groups.Results The effective rate of the observation group was 92.5%,which was significantly higher than 75.0% of the control group(x2=4.501,P<0.05).After treatment, the duration[(9.05±1.82)s vs (13.53±2.63)s]and lost time[(2.52±0.94)h vs (3.42±1.13)h]of apnea in the observation group were longer than those of the control group.The number of seizures[(22.15±4.16) vs (33.53±8.48)]was less than that of the control group,the differences were statistically significant(t=8.767,5.434,9.231,all P<0.05).After treatment, PaO2[(84.74±9.74)mmHg vs (71.46±8.53)mmHg],PaCO2[(42.62±4.15)mmHg vs (48.54±5.18)mmHg]and PaO2/FiO2[(221.52±26.51)mmHg vs (197.76±21.71)mmHg]in the observation group were significantly better than those of the control group(t=7.574,4.765,8.643,all P<0.05).The incidence rate of adverse reactions include tachycardia, hyperglycemia, hypoglycemia and restlessness had no significant difference between the two groups (15.0% vs 10.0%, P>0.05).Conclusion In the treatment of premature apnea, advanced caffeine citrate treatment can better improve the clinical symptoms and blood gas index, the curative effect is reliable.

Objective To observe the effect of Yiqi Huoxue Recipe on the expression of TGF-?1 and ?-IFN in rats with radiation-induced lung injury in different radiation time, and discuss the prevention and curative effect of Yiqi Huoxue Recipe and its possible action mechanism. Methods One hundred and twenty Wistar rats were randomly allocated into irradiation group (n =30), irradiation with Yiqi Huoxue Recipe-treated group (n =30), irradiation with ambroxol-treated group (n =30) and normal control group (n =6). The former three groups were irradiated at right hemithorax with a dose of 30 Gy (5 Gy per week). Animals were followed for 26 weeks after the first irradiation. The levels of serum TGF-?1 and ?-IFN of 6 rats in each group were assayed by ELISA at the end of 4th, 6th, 8th, 12th and 26th week after the first irradiation. Results In Yiqi Huoxue Recipe-treated group, the levels of serum TGF-?1 were significantly lower from the 4th week than that of the irradiation group (P0.05). Conclusion Yiqi Huoxue Recipe can inhibit the excretion of TGF-?1 and promote the excretion of ?-IFN. It suggested that Yiqi Huoxue Recipe might play an important role in the prevention and curation of radiation-induced lung injury.

Through the exploration and practice,the interventional nursing care has become an important part of Interventional Radiology,which bears a close relations to the pros and cons of the interventional therapeutic quality.The interventional nursing has been developing along the direction to become an independent nursing specialty.At the same time,various issues that affect the interventional nursing development start to emerge.At present,the setting up of a system to strengthen the establishment of the special care unit and human resources is urgently needed.The following measures are indispensable to promote the sustainable development of interventional care: to raise special awareness,to work out nursing routine and quality control standards,to explore the proficiency in order to stabilize nursing team,to pay attention to specialty education and to establish an integration mode for standardized training and professional development.
