Alimentary tract duplications are rare congenital anomalies that usually present in childhood and occasionally in adults. They are most common in the ileum, but can occur anywhere along the alimentary tract from the mouth to the anus. We report a 24-year-old woman who presented with a giant chylous ileum cyst duplication. To our knowledge, there is only one other report of a patient with a giant chylous cyst in the literature.

The goal of this study is to research the genetic characteristics and relationship between HN and P genes of NDV. The nucleotide sequence and deduced amino acid sequence were analyzed for the Hemagglutinin-neuramindase (HN) and Phosphoprotein (P) gene of twelve field isolates of Newcastle disease virus (NDV) during 1997-2005 in China. The HN and P gene sequences of fifteen NDV reference strains from GenBank were also used in this study. The molecular evolution distance of nucleotides and amino acids were calculated by MEGA 4.0 software, and analysis of variance and correlations were analyzed by SPSS11.0 software among different length sequences of the HN gene or P gene. The nucleotide and amino acids correlation of HN and P gene were analyzed respectively. The correlation of evolution distance and isolation year were also calculated. The results indicated that there were difference and good correlation of nucleotide and amino acid among different length sequences of the HN gene or P gene. These results revealed that the HN and P gene of NDV have the different response to selective pressure to adopt to landscape and closely relationship on heredity mutations. Nucleotide variations of HN and P gene have relationship with isolation year of strains.

To optimize the belt drying process conditions optimization of Gardeniae Fructus extract from Reduning injection by Box-Behnken design-response surface methodology, on the basis of single factor experiment, a three-factor and three-level Box-Behnken experimental design was employed to optimize the drying technology of Gardeniae Fructus extract from Reduning injection. With drying temperature, drying time, feeding speed as independent variables and the content of geniposide as dependent variable, the experimental data were fitted to a second order polynomial equation, establishing the mathematical relationship between the content of geniposide and respective variables. With the experimental data analyzed by Design-Expert 8. 0. 6, the optimal drying parameter was as follows: the drying temperature was 98.5 degrees C , the drying time was 89 min, the feeding speed was 99.8 r x min(-1). Three verification experiments were taked under this technology and the measured average content of geniposide was 564. 108 mg x g(-1), which was close to the model prediction: 563. 307 mg x g(-1). According to the verification test, the Gardeniae Fructus belt drying process is steady and feasible. So single factor experiments combined with response surface method (RSM) could be used to optimize the drying technology of Reduning injection Gardenia extract.

OBJECTIVETo establish an animal model of tractive spinal cord injury in rats in order to investigate its pathophysiological changes and clinical significance.

METHODST(12)-L(3) spines were tracted longitudinally with a special spinal retractor that was put on the proccessus transverses of T(12)-L(3) vertebrae of the rat after exposing T(13)-L(2) spinal cord via dual laminectomy. At the same tine, the spinal cord function was monitored by cortical somatosensory evoked potential (CSEP). Rats were randomly divided into four groups according to the amplitude of CSEP P(1)-N(1) wave, the amount of the decreasing P(1)-N(1) wave was 30% (the 30% group), 50% (the 50% group) and 70% (the 70% group), respectively. After traction, the changes of the neural behavioral function in rats were observed and the morphological structure of the spinal cord was analyzed quantitatively with image analysis system of computer.

RESULTSWith traction of spine, compared with the control group, the 30% group had no marked difference in combined behavioral score (CBS), neuron count, section area of neuron and Nissl body density, but the 50% and 70% groups had marked difference (P<0.01). Light microscope showed that the neuron volume was slightly small and the Nissl body was reduced lightly in the 30% group; the neuron space was enlarged and the neuron was degenerative, reductive, and dissolved, and the spinal cord structure was destroyed in the 50% and 70% groups.

CONCLUSIONSThe animal model of tractive spinal cord injury in rats is a reproducible, graded and clinic mimic. The model in this article provides a valuable assistance in further understanding etiopathology and screening effective measures of therapy and prophylaxis of the injury.

OBJECTIVETo study clinical outcomes of serial tightening of reserved suture threads in delayed incision closure.

METHODSFrom January 2005 to June 2013, 67 patients with delayed incision closure were treated with serial tightening of reserved suture threads. There were 37 males and 30 females, with an average age of 40 years old (ranged from 12 to 75 years old). Among them, 36 patients suffering from leg or forearm double fractures had the incision difficult to those primarily due to high tension or mergency; 13 patients had open wound which lasted for more than routine time for debridement and closure; 9 patients had wound infection; 9 patients had decompression incisions owing to compartment syndrome. The No. 4 suture thread was used to sew up the incision, and the 4 to 6 cm long thread was reserved at two ends of each thread. The reserved thread was tightened gradually from 2 to 4 days after operation according to conditions of swelling relieving. Finally, the reserved thread was not tied until the incision was completely closed.

RESULTSAfter operation, the reserved threads were tightened and tied for 1 time in 6 patients, 2 times in 23 patients, 3 times in 27 patients, 4 times in 11 patients. Postoperative closure time ranged from 3 to 9 days, with an average of 6.2 days. All the incisions got delayed primary healing.

CONCLUSIONThe method of serial tightening of reserved suture threads to close delayed incision closure avoids a second operation, which is simple and obtains a fine result.

·AIM:To study the influence factors and management of anterior chamber gas bubble during femtosecond flap creation for laser-assisted in situ keratomileusis ( LASIK) .·METHODS: Totally 9671 eyes of 4859 patients with femtosecond LASIK were included in this study. Preoperative, intraoperative and postoperative parameters of anterior chamber gas bubble patients were analyzed and compared.·RESULTS:A total of 51 cases (0. 53%) occurred anterior chamber gas bubble during femtosecond flap creation. There was no statistical difference between uncorrected visual acuity of postoperative 1mo (-0. 076 ± 0. 09 ) and preoperative best corrected visual acuity (-0. 08±0. 04; t=-0. 34,P=0. 74). And 33 eyes (65%) did not affect the pupil tracking, but there were 18 eyes ( 35%) unable to track the pupil successfully. There was no statistical difference in uncorrected visual acuity of postoperative 1mo between trace group (-0. 06 ± 0. 08 ) and no trace group(-0. 11 ± 0. 09; t = 1. 82, P = 0. 07). The highest incidence of anterior chamber gas bubble was at 9 point, followed by 3 point. There were no statistical differences in spherical equivalent refraction, corneal curvature, corneal diameter, anterior chamber volume, anterior chamber depth and intraoperative femtosecond laser energy between anterior chamber gas bubble eyes and the contralateral eyes (P>0. 05).·CONCLUSION: Anterior chamber gas bubble formation during femtosecond flap creation for LASIK is an uncommon event. It may affect the eye tracking. There is no obvious effect on early postoperative visual acuity if intraoperative disposed properly. The direct or indirect factors of anterior chamber gas bubble formation are unclear.
