BACKGROUND: Conventional endovascular stent-graft exclusion for Debakey Ⅲ type aortic dissection is complicated and the complication rates are relatively high. Moreover, their operating techniques have increased the risk of rupture of laminated break. OBJECTIVE: To evaluate the efficacy and safety of improved endovascular stent-graft exclusion for Debakey Ⅲ type aortic dissection by the innovative methods of interventional therapy. DESIGN, TIME AND SETTING: A retrospective case analysis. Cases were selected from Department of Cardiology, Affiliated Hospital of Gannan Medical College between October 2006 and March 2009. PARTICIPANTS: A total of 30 male patients with Debakey Ⅲ type aortic dissection were selected from Department of Cardiology, Affiliated Hospital of Gannan Medical College, aged 43-70(53.5±12.8) years. The time of onset was 5-45 days. METHODS: All patients underwent improved endovascular stent-graft exclusion for Debakey Ⅲ type aortic dissection by the innovative methods of intervsntional therapy. Fine wire bundled endovascular stent-graft were implanted by the innovative transmission and delivery methods in all patients, of which branch stent were implanted when the distance from the break of descending aorta to left subclavian artery was less than 10 mm. MAIN OUTCOME MEASURES: After the success of operation, aortic angiography was performed to detect stent-graft position, shape, break closure, internal leakage, and patency of the aortic arch branches. The situation of post-operative complications were observed. All cases were followed up by MRI to understand the complications such as aneurysm rupture, internal leakage and stent migration. RESULTS: A total of 33 fine wire bundled endovascular stent-graft were successfully implanted in 30 patients, including 4 branch stents. After the operation, 5 patients were verified endoleak, 3 of them were resolved by repeated stent distension and 2 were treated by implantation of another stent. Three months after the operation, 1 patient showed new rupture at the distal stent and then was successfully implanted a new stent. Three cases showed numbness of right lower extremity and 1 case showed intermittent claudication. In follow-up of 3-32 months, MRI scanning showed the reduction of the false cavity with the formation of intraluminal thrombus, the enlargement of true cavity, and no complications such as tumor rupture, internal leakage or stent displacement were found. CONCLUSION: Fine wire bundled endovascular stent-graft and the innovative methods of interventional therapy for endovascular thoracic aorta repair is an effective, less invasive and safe surgery with fast postoperative recovery, high success rate and few complications for patients with Debakey Ⅲ type aortic dissection, especially for high-risk patients.

Objective: To investigate the impact of acute myocardial infarction (AMI) concurrent acute kidney injury (AKI) on major adverse cardiac events (MACE) occurrence during hospitalization.
Methods: A total of 625 AMI patients treated in our hospital from 2011-01 to 2014-03 were retrospectively studied. According to AKI incidence, the patients were divided into 2 groups: AKI group,n=86 and Non-AKI group,n=539. Based on AKI network (AKIN) criteria, AKI group was further divided into 3 subgroups as AKI-I subgroup,n=45, AKI-II subgroup,n=27, AKI-III subgroup,n=14; based on renal function at admission, AKI group was divided into another set of 2 subgroups as Normal renal function subgroup [(eGFR≥90 ml/(min·1.73m2)],n=61 and Renal dysfunction subgroup [(eGFR<90/(min·1.73m2)],n=25. The incidence of MACE was compared among different groups and the risk factors for MACE occurrence in AMI patients during hospitalization were studied by multivariate Logistic regression analysis.
Results: The incidences of MACE in AKI group and Non-AKI group was (59.3% vs 16.9%),P<0.05; in Normal renal function subgroup and Renal dysfunction subgroup was (59% vs 60%),P>0.05. Multivariate Logistic regression analysis showed that AKI was the independent risk factor for MACE occurrence in AMI patients; elevated AKI stages were accompanied with the higher incidence of MACE accordingly, compared with AKI-I subgroup, the incidences of MACE in AKI-III subgroup and AKI-II subgroup were as (OR=1.68, 95% CI 1.14-1.69),P<0.05 and (OR=2.01, 95% CI 1.35-1.84), P<0.05 respectively.
Conclusion: AKI was closely related to MACE occurrence in AMI patients, effectively preventing AKI may improve the prognosis in relevant patients.

Objective To explore the clinical value of laparoscopic-assisted vaginal hysterectomy(LAVH)in large uterus.Methods Retrospective analysis was conducted on clinical data of 94 patients(whose uterus were as big as 10-18 gestational weeks)who received hysterectomy from January 2005 to March 2007,in which 56 cases were performed laparoscopic-assisted vaginal hysterectomy(LAVH group)and 38 cases vaginal hysterectomy(VH group).The operation time,blood loss,postoperative hospital stay,and the incidence of postoperative complications were compared between the two groups.Results Compared with VH group,there were a lower chance of abdominal hysterectomy(0/56 vs 5/38,?2=5.389,P=0.020),a shorter operation time [(149?11)min vs(179?14)min,t=-11.610,P=0.000] and a shorter postoperative hospital stay [(5.8?1.4)d vs(7.3?3.6)d,t=-2.825,P=0.006] in the LAVH group.There were no significant differences in blood loss,morbidity and time to first flatus between the two groups.Conclusions The LAVH extends the indications of VH,ensuring the safety of VH for the uterus bigger than 10 gestational weeks,therefore it is an operative procedure to be recommended.

OBJECTIVE:To study the potential of three kinds of Chinese medicines in combination with Ceftriaxone in inducing endotoxin release from Klebsiella for references of combined use of Chinese medicines and western medicines in the treatment of severe infections.METHODS:The amount of endotoxin released from Klebsiella after being treated in vitro by Ceftriaxone(high,medium and low concentrations)alone or in combination with 3 antibacterial Chinese medicines for 4 hours was compared.RESULTS:The amount of endotoxin released by Klebsiella in low concentration of Ceftriaxone either alone or in combination with Chinese medicines were the maximum but minimum in high concentration Ceftriaxone group.The amount of endotoxin released in low concentration group was larger than in blank group(without antibacterial treatment),and that released amount in Shuanghuanglian plus Ceftriaxone group was less than in Ceftriaxone alone group.CONCLUSION:Low concentration of Ceftriaxone can induce Klebsiella to release endotoxin,while Shuanghuanglian can reduce Ceftriaxone-induced release of endotoxin.

Objective To evaluate the effect of ultrasound-guided botulinum toxin A injection into the salivary glands in treating patients with sialorrhea attributable to brain damage.Methods Nine subjects with sialorrhea attributable to traumatic brain injury (n =5),cerebral infarction (n =3) and hypoxic ischemic encephalopathy (n =1) were recruited into the study.With the guidance of ultrasound,15 units (U) of botulinum toxin type A was injected into the highest and lowest points of the two parotid glands,and 20 U was injected into two points of both submandibular glands.The saliva flow rate and the severity and frequency of sialorrhea were recorded before the treatment and 1 week,4 weeks and 12 weeks later using the Drooling Scoring System (DSS).Results The saliva flow rate before treatment (0.49 ± 0.12 g/min) decreased significantly to 0.24 ± 0.08 g/min after 1 week,but then increased again to 0.28 ±0.12 g/min after 4 weeks and 0.34 ±0.11 g/min after 12 weeks.The average DSS severity score showed the same pattern:4.35 ± 0.48 initially 1.92 ± 0.37 after 1 week,1.92 ± 0.37 after 2 weeks and 2.32 ± 0.64 after 12 weeks.The DSS frequency score,however,remained significantly lower:3.56 ± 0.49 initially,2.01 ± 0.42 after 1 and 4 weeks and 2.28 ± 0.63 after 12 weeks.Conclusion Botulinum toxin type A can effectively improve the salivary secretion and sialorrhea attributable to brain damage.

An electrochemical aptasensor for Pb2+ was constructed based on the layer-by-layer assembly of graphene (GR) and anthraquinone -2-sulfonic acid sodium salt (AQMS) on the surface of Pb2+ aptamer. The mercapto-modified Pb2+ aptamer was first anchored on a gold electrode. Then the highly conductive material of GR was adsorbed on apt through the unique π-π stacking interaction, which was further used for the assembly and signal amplification of the electroactive AQMS. Upon interaction with Pb2+ ions, the apt on the aptasensor undergone conformational switch from a single-stranded form to the G-quadruplex structure, causing the GR assembled with AQMS releasing from the electrode surface into solution. As a result, the electrochemical signal of AQMS on the aptasensor was substantially reduced. Base on this concept, a useful platform for detection of Pb2+ ions was constructed. Under the optimal experimental conditions, the attenuation of peak currents (△Ipa ) showed linear relationship with the logarithm of Pb2+ concentrations (lgCPb2+) over the range from 5. 0×10-10 to 5. 0×10-8 mol/ L. The detection limit was estimated to be 6. 0×10-11 mol/ L.
