To discuss the influence of dexamethasion on lL-1β and TNF - α expression in suture - induced rabbit corneal neovascularization ( CNV ) and analyze the potential mechanism.
●METHODS: For 43 healthy rabbits, 40 were randomly selected for establishing CNV model in corneal stroma. The right eyes (group A) were received no medicine and the left eyes ( group B) were injected dexamethasone after successfully establishing the model. The no modeling 3 rabbits were normal control group. The morphologic change of corneal was observed with slit lamp microscope and the areas of CNV was calculated every day, then 8 rabbits were randomly chosen for sacrificing at 1, 4, 7, 14, 21d respectively. The pathological characteristics of CNV were observed after HE staining, and lL - 1β and TNF - α expression was detected by immunohistochemistry.
●RESULTS: CNV was grown at the 4d after suture, and the 7-14d was vigorous growth period. inflammatory cell infiltration appeared after HE staining, and CNV was located at the superficial stroma of cornea. lmmunohistochemistry results showed that lL - 1β and TNF - α expression was gradually increased with prolonged suture time. Compared with corneal stitch group, the rabbits cured by dexamethasone were found with less inflammatory cells infiltrating and neovescularization, moreover, the expression of lL - 1βand TNF-α decreased. There were statistical significance between the two groups (P<0. 05).
● CONCLUSlON: Dexamethasone can inhibit the CNV growth by controlling the inflammation of corneal and restraining lL-1β and TNF-α expression.

Objective To analysis and determine the possibility of the Citellus undulatus infected with Yersinia pestis surviving the winter in an experimental study, and to provide scientific experimental basis for the study on the mechanism of Yersinia pestis preservation. Method In 2006,09 to 2007,04 and 2007,09 to 2008,04 in Xinjiang Wusu-Gurtu natural foci of plague, under natural conditions, the over the winter process of Citellus undulatus carrying the plague bacteria was simulated, and 178 Citellus undulatus were infected with Yersinia pestis (1×107 Bacteria/mouse) using artificial injection method. One hundred seventy-eight Citellus undulatus infected with Yersinia pestis were kept into a construction of the black (1-5 ℃) basement (2 meters under the ground) in the plague focus. In doing so, these Citellus undulatuses almost simultaneously stepped into hibernation. After waking up from hibernation in following year in April, the survived mice carrying the plague bacteria were observed. Results Sixty-eight mice survived among the 178 infected with Yersinia pestis after 6 months of hibernation (through October to the following year in April), and the remaining 110 were all dead without pulling through the hibernation period. The survival rate was 38.2% (68/178). The organ culture of Yersinia pestis of the 110 dead mice(Citellus undnlatus) were tested, 67 were negative(-), 43 positive(+), with a positive rate of 39.1%(43/110). Among the rats with positive plague bacteria, the congestive pulmonary edema and the pathological changes of the hemorrhagic inflammation of the heart, liver, spleen, kidney and injection site could be seen clearly; the plague-free mice were not found to have any pathological changes. The survived 68 mice over the winter were autopsied and observed after being fed up for 20 days. No any pathological changes were found among these mice, and culturing of Yersinia pestis of the heart, liver, spleen, lungs and the tissue of injection site of these mice were all negative (-). Conclusions Citellus undulatus can carry Yersinia pestis during hibernation, but some fail to carry the bacteria through the entire process of hibernation persistently. Yersinia pestis was negative in the survived mice at the end of hibernation. The results showed that Citellus undulatus can not carry Yersinia pestis over the winter.

Abstract: The loop-mediated isothermal amplification (LAMP) technique is a technique for the specific and efficient amplification of target fragments at a constant temperature using two pairs of specially designed primers and a strand displacement activity DNA polymerase. LAMP technique is a simple, rapid, specific, sensitive and cost-effective nucleic acid amplification method, and therefore has a promising future in the field rapid detection of Mycobacterium tuberculosis and grassroots applications. In this review, the basic principles and characteristics of the LAMP technique, the main molecular markers for the diagnosis of tuberculosis, and the use of different molecular markers and various types of novel techniques in the diagnosis of pulmonary tuberculosis, extrapulmonary tuberculosis, and drug-resistant tuberculosis were described. The LAMP technique has been widely used in the diagnosis of tuberculosis with high sensitivity and specificity, but the technique still has some shortcomings. This paper reviews the progress of its application in tuberculosis in recent years and provides an outlook on its development, with a view to providing a rational research direction for rapid diagnosis of tuberculosis in a resource-limited environment.

Methods The clinical data of 4445 cases (5 530 hernias) who underwent LIHR at Ruijin Hospital from Jan 2001 to Dec 2015 were analyzed retrospectively.2 125 cases underwent 2 402 trans-abdominal preperitoneal procedure(TAPP),2 306 cases did 2 907 totally extraperitoneal (TEP),and 21 IPOMs in 20 cases.There were 3 216 indirect hernias (60.3％),1 164 direct hernias (21.8％),399 recurrent hernias (7.5％),479 complex hernias (9.0％),and 72 femoral hernias (1.4％).The median time of follow-up is 51 months with a range between 7 and 187 months.Results The average operation time was 27.1 ± 8.7 min for unilateral hernia repair,and 43.0 ± 11.0 min for bilateral hernia repair.The average hospital stay was 1.4 ± 1.1 d.There were 250 seroma (4.7％),68 urinary retention (1.3％),23 transient neuropraxia (0.4％) and 3 paralytic obstruction of intestines (0.1％).Severe complications included 1 port site hernia,1 intestinal injury,and 1 mechanical intestinal obstruction.After a medium follow-up of 51 months,there were 13 recurrent cases (0.24％),including 5 cases after TAPP,7 after TEP,1 after IPOM.Conclusion LIHR is a safe and efficient technique for hernia repair.

Objective To reduce immunogenicity of porcine skin by removingα-Gal epitopes expressed in cell surface and extracellular matrix using recombinant α-galactosidase produced by Bacteroides fragilis.Methods The porcine skin was harvested from healthy 2-month-old pigs without any skin disorders before being sterilized by iodine and 75%alcohol, respectively.Enzymatic removal of α-Gal antigen was followed by washing with PBS.The α-Gal antigen in the prepared porcine skin was measured with immunofluorostaining of cryosections and the residual enzyme was measured with a double-antibody sandwich ELISA method.Enzymatic removal procedures were optimized by detecting residual enzyme and the effi-cacy ofα-Gal removal under different enzymatic and washing conditions.Results Efficient enzymatic and washing methods were established to removeα-Gal antigen.Theα-Gal removal efficacy was above 90% and residual enzyme was undetect-able (αprescribed minimum ofα-galactosidase detection with indirect ELISA was 1 ng/ml) .Conclusion It is feasible to efficiently removeα-Gal antigen under these enzymatic and washing conditions, and a method of producing low-immunoge-nicity pig skin dressing for burn is established.
