Based on the competition reaction of target protein, aptamer probe, padlock probe and complementary sequence, a highly sensitive fluorescent aptasensor was developed in this study in combination with rolling circle amplification. In the absence of target protein, the ligation-rolling circle amplification reaction was repressed because the complementary sequence hybridized with aptamer probe to form double-stranded duplex. While in the presence of target protein, the target molecules bound specifically with aptamer probe, inducing displacement of the complementary sequence and hybridization with padlock probe. The padlock probe was circularized with the assistance of E. coli DNA ligase, and the rolling circle amplification process could be accomplished by Phi 29 DNA polymerase. The amplification product contained thousands of repeated sequences which could hybridize with the loop of molecular beacon ( the detection probes) , resulting in a significant fluorescence signal. The effects of length of complementary DNA ( CDNA ) sequence and concentration of padlock probe were investigated. Under the optimized experimental conditions, the model target protein thrombin could be highly sensitively detected by the proposed aptasensing system in a linear range of 0 . 067-32 . 4 nmol/L with a detection limit of 0 . 03 nmol/L ( approximately 90 amol target molecules). Moreover, the presented sensing method was universal for other target analysis by skillfully design of the sequence of aptamer probe and related oligonucleotides.

Objective To investigate the variation law of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values in patients with cerebral infarction, and to explore the relationship between the changes and the prognosis of cerebral infarct patients. Methods Sixteen patients with cerebral infarction were recruited and divided into 2 groups:good recovery and poor rehabilitation. ADC and FA values were calculated in infarct areas and control areas which were the regions with symmetrical position and the same area as infarct areas. The difference of ADC and FA values in patients at acute and earlier chronic stage between the two areas were analyzed. Results ①At acute stage, ADC values in infarct areas were lower than those in control areas (P<0.05). At early chronic stage, there was no significant difference of ADC values between infarct areas and control areas (P>0.05), moreover ADC values were higher than that at acute phase (P<0.05). ②FA values in infarct areas were lower than those in control areas at both acute and early chronic stage (P<0.05). At early chronic stage, FA values were lower than those at acute stage (P<0.05). ③There was no significant difference of ADC and FA values at both acute and early chronic stage between good recovery group compared with poor rehabilitation group (P>0.05). Conclusion There are certainly rules in changes of ADC and FA values in patients with cerebral infarction at acute and earlier chronic stage.

Objective To compare the ear baric function between 4000m altitude chamber test with inhaling air and 6900m altitude chamber test with inhaling pure oxygen.Methods Eleven healthy male volunteers attended two tests as two groups by self-comparison. As the air group the volunteers inhaled air at 4000m, while as the pure oxygen group they inhaled pure oxygen at 6900m altitude, and the time interval between the two tests was more than two weeks. During the test, the volunteers breathed air or pure oxygen at random for 1h, and then were exposed at a speed of 20m/s to the target altitude for 5min. Hereafter they were sent back to the ground at the same speed. The changes of subjective symptoms, degree of tympanic congestion, acoustic immitance index and pure-tone auditory threshold were recorded before and after the test. The acoustic impedance index and pure-tone threshold were statistically analyzed.ResultsFour volunteers (4 ears) in air group and 7 volunteers (7 ears) in pure oxygen group reported ear pain in altitude chamber exposures, respectively. The pain-triggering altitude was higher in the pure oxygen group. Immediately after tests, there were 3 (3 ears) and 5 volunteers (5 ears) with Ⅲ degree congestion of the tympanic membrane in the two groups respectively. Four volunteers (6 ears) developed gradually aggravated hemorrhages after altitude exposure. And the tympanic membrane congestion difference between groups was statistically significant at 3 and 24h after tests (P<0.01). The type A tympanogram appeared in 11 (15 ears) and 11 (14 ears) volunteers respectively immediately after tests. The increase of static compliance value was significantly greater in pure oxygen group than in air group immediately after tests (P<0.05), the decrease of middle ear pressure was more significant in pure oxygen group than in air group at 3 and 24h after tests (P<0.05). Both the two altitude exposure tests resulted in eustachian tube dysfunction. At 3 and 24h after the tests, the increase of individual frequency pure-tone threshold was significantly higher in pure oxygen group than in air group (P<0.05).Conclusion Breathing pure oxygen and lifting height could increase the screening degree of ear baric function test in hypobaric chamber, and have greater influence on degree of tympanic congestion, acoustic immittance and pure-tone auditory threshold in 24 hours.

OBJECTIVETo determine the feasibility and efficiency of terminating atrial flutter (AFL) and atrial fibrillation (AF) using synchronous low-energy shocks delivered through a novel transesophageal electric balloon electrode system.
METHODSBy using a novel electric balloon electrode system, we attempted 91 transesophageal cardioversions in 52 patients, to treat 53 episodes of AFL and 38 episodes of AF.
RESULTSOf the 40 patients of AFL that failed to respond to drug therapy, 37 (92.5%) were successfully countershocked to sinus rhythm by transesophageal cardioversion, with a mean energy of (22.70 +/- 4.50) J (20 - 30 J). Of the 19 patients in AF, transesophageal cardioversion was successful in 16 (84.2%) cases, requiring a mean delivered energy of (17.38 +/- 8.58) J (3 - 30 J). There were no complications such as heart block or ventricular fibrillation, and no evidence of esophageal injury.
CONCLUSIONSTransesophageal cardioversion using an electric balloon electrode system is an effective and feasible method for the treatment of AFL and AF. It requires low energy and no anesthesia, leads to less trauma, and shows a high cardioversion success rate that may prove valuable in the management of tachyarrhythmias.

OBJECTIVETo compare the long-term survival and postoperative complications of distal gastric cancer patients between Billroth I((BI() and Billroth II((BII() reconstruction.
METHODSClinicopathological data of 992 patients with distal gastric cancer who underwent D2 curative gastrectomy in our department from May 2008 to April 2015 were recorded, including 207 patients of BI( reconstruction and 785 of BII( reconstruction, were retrospectively analyzed. Patients presenting a previous history of cancer, gastric resection or cytotoxic chemotherapy, and those presenting liver or intraperitoneal tumor dissemination or unresectable infiltration into contiguous organs were excluded. Patients in BI( and BII( group were selected using gmatch methods based on age (±10 years), gender, tumor size (±1 cm), differentiated degree and depth of invasion in order to reduce the selection bias of clinicopathological characteristics. The final number of patients matched was 191 respectively.
RESULTSCompared with BII( group, the BI( group had a significantly shorter operation time (181.7 min vs. 220.7 min, P=0.000) and a shorter postoperative hospitalization stay (7.6 days vs. 8.1 days, P=0.046). The postoperative complications including anastomotic leakage, wound dehiscence, wound infection, intraperitoneal hemorrhage, intestinal obstruction, duodenal stump fistula, pulmonary infection and fever had no significant difference(P>0.05). Three-year survival between two groups was comparable (82.9% vs. 78.7%, P=0.379).
CONCLUSIONSCompared with BII(, BI( reconstruction is more suitable for patients with distal gastric cancer.
