OBJECTIVETo identify the Cynomorii Herba and its analogues species using DNA barcoding technique.

METHODTotal genomic DNA extracted from all materials using the DNA extraction kit. The internal transcribed spacer 2 (ITS2) regions were amplified using polymerase chain reaction (PCR), and purified PCR products were sequenced bi-directionally. Sequence assembly and consensus sequence generation were performed using the CodonCode Aligner 3.7.1. The Kimura 2-Parameter (K2P) distances and GC content were computed using MEGA 5. 0. Species identification analyses were conducted through the species identification system for traditional Chinese medicine and neighbor-joining (NJ) trees.

RESULTThe ITS2 sequence lengths of Cynomorii Herba were 229 bp. The average intra-specific genetic distances of Cynomorii Herba were 0.003. The average inter-specific genetic distances between Cynomorii Herba and its adulterants species were 0.760. The results showed that the minimum inter-specific divergence is larger than the maximum intra-specific divergence. The species identification system for traditional Chinese medicine and NJ trees results indicated that Cynomorii Herba and its adulterants species can be easily identification.

CONCLUSIONThe ITS2 region is an efficient barcode for identification of Cynomorii Herba, which provide a new technique to ensure clinical safety in utilization of traditional Chinese medicine.

OBJECTIVEBy using orthogonal design method to optimnize prescription of pulsed electric field at Jiaji (EX- B 2) points for spinal cord injury (SCI).

METHODSFifty six patients of SCI were selected, in which 36 cases were divided into orthogonal design trial and 20 cases were into clinical verification. With 36 patients who received orthogonal design trial, Frankel grading scale was used as observation index to screen optimal prescription of pulsed electric field. Pulse frequency (factor A) included low frequency (factor A(I), 10(2) Hz). moderate frequency (factor A(II), 10(4) Hz) and high frequency (factor A(III), 10(3) Hz); pulse amplitude (factor B) included 0-30 V (factor B ), 0-60 V (factor B(II)) and 0-90 V (factor B(III)); pulse width (factor C) included 0.1 ms (factor C(I)). 0.6 ms (factor C(II)) and 0.9 ms (factor C(III)); acupuncture time (factor D) included one month (DI), three months (D(II)) and five months (D(III)). Twenty patients were used for clinical efficacy observation and the effects of screened optimal pre scription of pulsed electric field at Jiaji (EX-B 2) points combined with regular rehabilitation training on spasm se- verity, score of sensory and motor functions, Barthel index and Frankel score were observed.

RESULTS(1) As results of orthogonal design trial, the optimal prescription was A(III) B(III), C(I), D(III), which were high frequency (10(3) Hz), 0-90 V of pulse amplitude, 0.4 ms of pulse width and 5 months of treatment time. (2) As results of 20 patient clinical verification, Ashworth score, tendon reflex and clonus were all significantly improved (P<0.001, P<0.01), the scores of sensory and motor functions were evidently improvedtl (P<0.001, P<0.05), and Barthel in dex and Frankel score were also enhanced (P<0.001, P<0.05).

CONCLUSIONThe optimal prescription of pulsed electric field at Jiaji (EX-B 2) points for spinal cord injury is high frequency (10& Hz), 0-90 V of pulse amplitude, 0.4 ms of pulse width and 5 months of treatment time. The optimal prescription of pulsed electric field at Jiaji (EX-B 2) points combined with regular rehabilitation could obviously improve spasm severity, enhance senso- ry and motor functions, and ameliorate activity of daily life and Frankel score.

Objective To explore the clinical efficacy and satety of LFK-SLT30 semiconductor laser combined with polidocanol for the treatment of varicose veins of the lower extremities.Methods The clinical data of 105 patients treated by traditional surgery (surgery group) and 113 patients with endovascular laser treatment (EVLT) combined with polidocanol (combination group) were retrospectively analyzed from Apr 2013 to Apr 2015.Results The operative time [(50 ± 12) min vs.(70 ±10)min] and blood loss [(19 ± 6)ml vs.(41 ± 8)ml] between combination group and surgery group were significantly different (P ＜ 0.05).The rate of complications in surgery group was significantly higher than that in the combination group[15.2％ (16/105)vs.6.3％ (7/113),x2 =4.717,P =0.030].The overall 1',2' and 3 year follow-up rate was 85.3％ (186/218),76.6％ (167/218),and 60.6％ (132/218).The average follow up was (20 ± 13)months.No significant difference existed in the rate of recurrence [0 vs.3.5％(4/113),x2 =3.786,P=0.123] between the two groups.Conclusions EVLT combined with foam sclerotherapy is as effective as surgery,while resulting in less complications,less invasive,safer and more effective for the treatment of varicose veins of the lower extremities.

In order to construct a prokaryotic expression vector of human receptor syt II N-fragment and to express recombinant MBP-Syt fusion protein in E.coli and to purify and identify its activity. According to codon preference of E.coli, a DNA fragment encoding human syt II N-fragment was synthesized, and then cloned into prokaryotic vector pMAL-c2x for sequencing. Then the recombinant plasmid pMAL-Syt was introduced into E.coli ER2566 by transformation for expression and the obtained engineered bacteria were induced by IPTG. The fusion protein was purified by amylose resin affinity chromatography and identified by SDS-PAGE and Western blot. The binding activity of the protein was determined by ELISA. It is concluded that MBP-Syt protein is of good binding activity.

Background Corneal blindness caused by ocular surface disease is one of the main reasons for the global blinding corneal diseases.With the development and progress of tissue engineering technology,tissueengineered cornea offers a new approach to the treatment of ocular surface disease.Objective This study was to obscrve the growth and differentiation of human umbilical cord mesenchymal stem cclls (UC-MSCs) on thc corneal stroma of receipts and investigate the feasibility of human UC-MSCs differentiated into corneal epithelium-like cells and the reparation of injury cornea.Methods Human UC-MSCs were isolated from human umbilical cord using collagenase Ⅳ digestion and passaged in DMEM/F12 containing fetal bovine serum in vitro.The immunophenotype of cultured human UC-MSCs was evaluated by flow cytometry.The differentiated osteoblasts from the human UC-MSCs by directional induce was identified.Twenty-four New Zealand albino rabbits were randomly divided into 2 groups.The human UC-MSCs were cultured on porcine corneal matrix without corneal epithelium for 4 days and then transplanted onto the 12 left eyes of 12 New Zealand albino rabbits,and porcine corneal matrix without corneal epithelium was transplanted onto the left eyes of other 12 New Zealand albino rabbits as control group.The rabbits received keratoplasty were examined using in vivo confocal microscope through focusing(CMTF).The eyeballs were taken off after 2,4 and 8 weeks,the growth and differentiation,expression of cytokeratin 3 (CK3),CK12 and ATP-binding cassette superfamily G memben 2 (ABCG2)of human UC-MSCs were observed by histopathology and immunofluorescence staining.This use of the experimental animals complied with ARVO Statement.Results Digestive human UCMSCs formed round in shape and was large in size.The attached cells displayed long-fusiform shape like fibroblasts.The cultured human UC-MSCs phenotype was CD105+/CD29+/CD44+/CD34-/CD45-and could be induced toward osteoblast differentiation under the appropriate experimental conditions.Human UC-MSCs grew well on the porcine corneal matrix.The corneal grafts survived wcll without rejection till the experiment end in experimental eyes,but the rejection of corneal graft occurred in control eyes.Confocal microscope could observe corneal epithelium-like cells.The corneal epithelium cells showed the positive response for CK3 and CK12 and absent response for ABCG2.Conclusions Human UC-MSCs with porcine corneal matrix can survive,proliferate and differentiate into corneal epithelium-like cells after transplanting onto the corneal stroma of rabbits.This result suggests that human UC-MSCs is able to repair and reconstruct the injured corneal surfaces.
