The aim of this study was to explored the mechanism of inhibitory effect of chloroquine on IL-6 release induced synergistically by bacterial DNA and endotoxin. Before experiment mice were sensitized for 1 hour with D-GalN by I.P. injection. Mortality within seven days was observed after mice were challenged with CpG ODN or LPS with or without chloroquine treatment. ANA-1 cell line cells were cultivated in vitro. We investigated the influence of chloroquine on IL-6 release induced by both EC DNA and LPS. Expressions of TLR4 and TLR9 and activation of NF-?B p65 were investigated in cultured THP-1 cells pretreated with chloroquine and stimulated by EC DNA and LPS. The results showed that all mice died within 4 hours after challenged with CpG ODN and LPS. Only 4 or 5 mice pretreated with chloroquine (30mg/kg) died after challenged with CpG ODN and LPS (P

BACKGROUND: What kind of traumatic changes could be observed in remote lumbar spinal cord after high-speed steel ball induced sciatic nerve injury?OBJECTIVE: To study the ultra structural changes of lumbar spinal cord motor neurons after the sciatic nerve injury due to high-speed steel ball.DESIGN: Retrospective randomized controlled study with experimental animals as subjects.SETTING: The field operation research institute of a military medical university college.MATERIALS: This study was carried out at the Ballistic Laboratory of Research Institute for Surgery from May 2001 to December 2002. Sixty-five SPF flap-eared rabbits of either gender weighing from 2.5 to 3.0 kg were provided by the Experimental Animal Center of Daping Hospital Affiliated to the Third Military Medical Univeristy of Chinese PLA. All the rabbits were divided randomly into normal control group( n = 5), firearms injury group (n = 30) and cutting injury group( n = 30) . The two latter groups were subdivided into one-day, three-day, one-week, two-week, 4-week and twelve-week groups with 5 rabbits in each group.METHODS: The rabbits in the firearms injury group were injured at the midpoint of lateral posterior body surface projection of the right sciatic nerve with 0. 38 g steel ball containing 0.65 g detonators. The right sciatic nerve was cut at the same injury level in the cutting injury group.MAIN OUTCOME MEASURES: The following pathologic changes of the lumbar spinal cord were observed with optical and electronic microscope at posttraumatic day 1, day 3 and week 1, week 2, week 4 and week 12 respectively.RESULTS: Micro-hemorrhage, neuron swelling and vacuoles were observed in the firearms injury group and the number of motor neurons decreased significantly, but these changes were unobservable in the cutting injury group.CONCLUSION: Compared with the cutting group, the injury to the spinal cord was severer in the firearms group and the survival neurons were less.

In order to change the situations such as students’passivity and low enthusiasm in the traditional experimental teaching of Microbiology and improve students’comprehensive qualities,exploration and attempt on experimental teaching reforms including teaching contents,teaching modes,laboratory management and evaluation system of examination were done.Teaching practices showed that the normalized ex- periment syllabus based on the correct orientation of experimental teaching of Microbiology,the actualization of teaching mode of basic skill training-integrated experiment-designed experiment and the management of opening laboratory were effective measures in improving experimental teaching of Microbiology.

AIM: To construct a recombinant vector containing gloverin and express it in vitro by Rapid Translation System(RTS500). METHODS: The gloverin cDNA was amplified by PCR and inserted into the prokaryotic expression vector pIVEX2.3. The recombinant product was identified by PCR and enzyme digestion. The positive reconstructed expression plasmid pIVEX2.3-G was expressed by RTS500 in vitro. The expressed protein was identified by SDS-PAGE and western blotting. RESULTS: Positive recombinant plasmid pIVEX2.3-G was successfully constructed. Target protein of 13.8 Kda with 6-his tag was detected by SDS-PAGE and western blotting. CONCLUSION: Gloverin polypeptide is successfully expressed in inactive E.coli in vitro.

OBJECTIVE To explore the situation of physical and mental health and related factors among voluntary blood donors in Anhui Province in order to provide scientific basis to the improvement of voluntary blood donation.METHODS Taking the method to study the situation of blood donors,and selecting five representative cities(the southern part of Anhui: Huangshan and Chaohu,the central part of Anhui:Hefei and the northern part of Anhui:Suzhou and Bozhou).Totally 978 blood donors were investigated by SRHMS and detected their health,behavior and knowledge.RESULTS There were 558(57.1%)first time donors,with 85.1% of higher educational level,and other 420(42.9%) donated blood more than two times,with 91.0% of higher educational level.They all were mainly students(78.32% vs 63.10%).The total equipartition score of volunteer blood donators on health was 347.95?43.92,it was 143.54?16.40 on physiological health,110.59?22.89 on psycho-health,and 94.51?13.78 on social health.CONCLUSIONS Nowadays the volunteer blood donors are mainly from the students and the people with higher cultural level in Anhui Province.We should strengthen the propaganda on the work of volunteer blood donation,especially in other Provincial areas and among people with other occupations.Establishing a permanent group of volunteer blood donation can ensure the transfusion safety from beginning.

AIM:To perform a new method for orbital implant and contracted socket through one time and its results. ·METHODS:Totally 114 patients 114 eyes, from January 2008 to June 2014, with contracted socket participated in this study. We incised the bulbar conjunctiva horizontally and excised scar tissue, then implanted the hydroxyapatite in the four extraocular muscles and tightly sutured the Tenon ' capsule. After that, we put the superior and inferior conjunctival petals backwards and sutured them to the Tenon ' s capsule. All the patients were divided into four groups according to the vertical diameter length of the conjunctival defect area:GroupⅠ:≤5mm; Group Ⅱ: 6-10mm; Group Ⅲ: 11-15mm; and Group Ⅳ: ≥16mm. These patients were followed up for 6mo to 3y to observe the conjunctival sac shaping and growth of conjunctiva. ·RESULTS:There were 64 cases in GroupⅠ, 31 cases in Group Ⅱ, 16 cases in Group Ⅲ and 3 cases in Group Ⅳ. All patients ' conjunctival defect was covered by new conjunctiva and scar tissue 4 to 6wk after surgeries. Ten cases had contracted socket; 2 cases had orbital implant exposure, requiring reoperation. Of the 114 cases, 8 had contracted socket and could use a smaller conformer, 106 could use a normal size conformer. ·CONCLUSION: When the conjunctival defect was ≤15mm, this new method can address the orbital implant and contracted socket at the same time. While it was ≥16mm, flap transplantation is necessary.
