BACKGROUND:Whether controling of post-injury inflammatory response combined with neural stem cel (NSC) transplantation can improve the curative efficacy for spinal cord injury stil remains unclear. OBJECTIVE:To investigate the repair of spinal cord tissue, myelin regeneration, axon regeneration, motor function recovery and the possible mechanism after early application of tumor necrosis factor α antagonist (Etanercept) combined with tyrosine kinase C (TrkC) gene-modified NSC transplantation. METHODS:TrkC-overexpressed NSCs (TrkC-NSCs) were constructed by lentiviral transfection technique. The rat models of spinal cord transection injury were prepared, and then subjected to Etanercept combined with TrkC-NSCs transplantation. The number of neurons and neuroregeneration after injury were measured by Nissl's staining, immunofluorescence and western blot. The rat motor function was detected by Basso Beattie Bresnahan score and evoked potential. The myelin regeneration was detected by electron microscopy and toluidine blue staining. RESULTS AND CONCLUSION:Compared with the other groups, the Etanercept combined with TrkC-NSCs transplantation group had more survived anterior horn motor neurons at 28 days after injury, more myelin-encapsulated axons, higher Basso Beattie Bresnahan score, greater amplitude of the evoked potentials, and relatively shorter latency (alP < 0.05). These findings indicate that early application of tumor necrosis factor-α antagonist combined with TrkC-NSCs transplantation after spinal cord injury in rats can effectively promote myelin regeneration, axon regeneration, and further promote motor function recovery.

Objective To evaluate changes in retinal expression of three heat shock proteins(HSPs)HSP27,HSP70 and HSP90 in normal and experimental glaucomatous rats's retina,and to explore the potential relationship between HSPs with glaucoma optic neuropathy.Design Experimental study.Participants 60 Wistar rats.Methods Rats were randomly divided into ocular hypertension group(n=30)and sham control group(n=30).The right eye was designed as the experimental eye,and the left as the control eyes.Intraocular pressure(IOP)was elevated by using underwater bipolar electro coagulation condensate 3 episcleral and limbal veins on the right eye of rats to establish of animal models of glaucoma.IOP were monitored twice weekly with a Tonopen.In treated eyes,IOP ranged from 27 to 35 mmHg throughout the study.Rats were killed with euthanasia at 10,20,or 60 days following the occurrence of ocular hypertension,with retina dissected free and protein isolated.Protein was used for Western blot analysis and probed with specific HSP antibodies,and normalized to ?-actin levels.Main Outcome Measures IOP,Western bolt.Results Western blot analysis demonstrated that HSP27 protein levels in the retinas were elevated as much as 197% at 10,20 and 60 days following the induction of ocular hypertension.No changes in protein levels were observed for HSP70 or HSP90 in retina from ocular hypertensive eyes.Conclusions The stress protein HSP27 is upregulated in retinas from ocular hypertensive rats.No changes in HSP70 or HSP90 were observed.The upregulation in HSP27 appears to be a gene specific event associated with elevated IOP,its expression may be a potential relationship associated with optic neuropathy in glaucoma.

This study aims at trying to establish a novel method of sterility test for injections based on biothermodynamics, in order to overcome the deficiencies of routine sterility tests such as long detecting cycle, low sensitivity and prone to misjudgments. A biothermodynamics method was adopted to rapidly detect the microorganism contamination of injections by monitoring the heat metabolism during the growth of microbe. The growth rate equal to or greater than zero and the heat power difference of P(i) and P(0) with three folds higher than the noise of baseline were chosen as indexes to study the heat change rule of microbe. In this way, the effectiveness of the new method to detect strains required by conventional sterility test or in injection samples was also investigated. Results showed that the Gram-positive bacteria, Gram-negative bacteria and fungi demanded by sterility testing methodology could be detected by biothermodynamics method within 10 hours, with the sensitivity lower than 100 CFU x mL(-1). Meanwhile, this method was successfully applied to the sterility test of Compound Yinchen injection (FFYC), Shuanghuanglian powder injection (SHL) and Compound Triamcinolone injection (TAND) which were sterilized with different degrees. Therefore, the biothermodynamics method, with advantages of fast detection and high sensitivity, could be a complementary solution for conventional sterility tests.

OBJECTIVETo investigate the clinical effect of microsurgical vasoepididymostomy and/or vasovasostomy in the treatment of obstructive azoospermia.

METHODSThis study included 76 patients with obstructive azoospermia, 53 treated by bilateral vasoepididymostomy (8 involving the epididymal head, 18 involving the epididymal body, 5 involving the epididymal tail, and 22 involving the epididymal head, body and tail), 14 by unilateral vasoepididymostomy, and the other 9 by unilateral vasoepididymostomy + unilateral vasovasostomy (including cross anastomosis). We followed up the patients for 2 to 16 months for the patency rate, routine semen parameters, and pregnancy outcomes.

RESULTSThe success rate of bilateral vasoepididymostomy, unilateral vasoepididymostomy, and unilateral vasoepididymostomy + unilateral vasovasostomy (including cross anastomosis) were 62.26% (33/53), 35.71% (5/14), and 77.78% (7/9), respectively. The average sperm concentrations in the three groups of patients were (27.9 +/- 5.74), (11.8 +/- 8.33), and (19.9 +/- 7.53) x 10(6)/ml, the average total sperm counts were (65.6 +/- 13.71), (28.0 +/- 15.86), and (69.2 +/- 28.59) x 10(6), and the mean rates of progressively motile sperm were (22.3 +/- 3.18), (11.0 +/- 9.77), and (15.8 +/- 5.05)%, respectively. The success rates of bilateral vasoepididymostomy that involved the epididymal head, body, tail, and all the three parts were 62.5, 72.22, 60, and 54.55%, respectively. Natural pregnancy was achieved in 8 (10.53%) of the total number of cases.

CONCLUSIONMicrosurgery is effective for the treatment obstructive azoospermia. Unilateral vasoepididymostomy + unilateral vasovasostomy is superior to the other procedures, followed by bilateral vasoepididymostomy. Bilateral vasoepididymostomy involving the epididymal body may achieve a slightly better effect than that involving the other epididymal parts.

Identification accuracy of traditional Chinese medicine is crucial for the traditional Chinese medicine research, production and application. DNA barcoding based on the mitochondrial gene coding for cytochrome c oxidase subunit I (COI), are more and more used for identification of traditional Chinese medicine. Using universal barcoding primers to sequence, we discussed the feasibility of DNA barcoding method for identification commonly-used medicinal snakes (a total of 109 samples belonging to 19 species 15 genera 6 families). The phylogenetic trees using Neighbor-joining were constructed. The results indicated that the mean content of G + C(46.5%) was lower than that of A + T (53.5%). As calculated by Kimera-2-parameter model, the mean intraspecies genetic distance of Trimeresurus albolabris, Ptyas dhumnades and Lycodon rufozonatus was greater than 2%. Further phylogenetic relationship results suggested that identification of one sample of T. albolabris was erroneous. The identification of some samples of P. dhumnades was also not correct, namely originally P. korros was identified as P. dhumnades. Factors influence on intraspecific genetic distance difference of L. rufozonatus need to be studied further. Therefore, DNA barcoding for identification of medicinal snakes is feasible, and greatly complements the morphological classification method. It is necessary to further study in identification of traditional Chinese medicine.

5 mm and ≤8 mm in 4 cases.The mean value was 4.2 mm. Four patients noticed reduction in their vision and two had diplopia.Those patients were examined by CT or MR.Direct venography was performed in each patient.After the diagnosis of OVM was confirmed, intralesional injection of BLE was performed.The efficacy of the treatment and complications were observed during the following 8 to 42 months(mean 23 months).Results The BLE were successfully injected in all the patients.All patients had resolution of proptosis and diplopia.Three patients gained improvement of visual acuity.The periorbital swelling occurred in all patients after operation and resolved within 1 week without special treatment.Other complications,such as orbital hemorrhage and periorbital scar,were not observed during following-up.Conclusion Intralesional injection with BLE is convenient,safe and efficient for the treatment of OVM.

To identify some medicinal animals of Lacertilia, in total 59 individuals belonging to 12 species 7 genera 3 families, we used the universal barcoding primers to sequence these species, compared with other homologous sequences (564 bp) obtaining from the GenBank and finally constructed phylogenetic trees using Neighbor-joining, Maximum parsimony and Bayesian inference, respectively. As a result, the mean content of G + C (46.5%) was lower than that of A + T (53.5%). As calculated by Kimera-2-parameter model, the whole individuals mean distance for interspecies and intraspecies was 35. 5% and 1.7%, respectively. The mean distance for interspecies was 21 times as much as that for intraspecies. The mean distance for intraspecies of Gekko swinhonis, Hemidactylus frenatus and G. gecko was greater than 2%, respectively. Further analyses suggested that geographical groups of the three species might be of different subSpecies, even species. Of course, incorporating morphological characters and other unlinked genetic markers in future studies will offer further insights into the divergence. On the basis of phylogenetic trees constructed by COI, our results indicated that the taxonomy of the category (family, genus, and species) by DNA barcoding is consistent with morphological characters. Therefore, DNA barcoding is a useful tool for both identification and phylogeny of medicinal animals of Lacertilia, particularly for nonprofessor identifying authentication of Chinese crude drugs of these species.
