Objective　To study killing effect of plasmas ozo ne water on microorganisms by plasmas ozone disinfection solution through plasma s ozone resulting from discharge along surface disinfection solution produced by machine and its effect factors. Methods　Quantitative solut ion test was used to study killing action of plasmas ozone disinfection water to E. coli and staphyrococcus aureus, and to study its eff ect factors. Results　Plasmas ozone water could kill 99.9% E. coli and staphyrococcus aureus after 15 min. The kill ing effect was affected by organism. With the increasing of organism concertrat ion, the killing efficacy increased. Conclusions　Plasmas ozone can effectively kill microorgnisms in water and the efficacy was affected by org anism.

Objective To investigate the effects of lactoferrin on activity of PKG in spinal dorsal horn in a rat model of neuropathic pain(NP).Methods Thirty-two male SD rats weighing 200-250 g were randomly divided into4 groups(n = 8 each): sham operation group(group S),NP group,lactoferrin group and KT5823(an inhibitor of PKG)group.Neuropathic pain was produced by placing loosely constrictive ligatures around the common sciatic nerve in group NP,lactoferrin and KT5823,while the sciatic nerve was only exposed but not ligated in groupS.In group S and NP,normal saline 10 μl + 50% dimethyl sulfoxide(DMSO)10 μl were injected intrathecally.Lactoferrin 100 μg + 50% DMSO 10 μl were given intrathecally in group lactoferrin.Lactoferrin 100 μg + KT5823 10 μl were given intrathecally in group KT5823.The paw withdrawal latency(PWL)to a thermal nociceptive stimulus was measured every 30 min within 180 min after administration.The rats were then sacrificed and the spinal cord was removed.The activity of PKG in the spinal dorsal horn was determined by immunofluorescence.Results Compared with group NP and KT5823,the PWL was significantly prolonged after administration in group lactoferrin and the PKG activity was significantly increased in group lactoferrin(P ＜ 0.05).There was no significant difference in the parameters mentioned above between group NP and group KT5823(P ＞ 0.05).Conclusion Lactoferrin reduces NP by inhibiting the activity of PKG in spinal dorsal horn in rats.

Objective To investigate protective effects and mechanism of folic acid on brain neural cells in preeclampsia rat model.Methods Adult pregnant Wistar rats were randonly divided into 4 groups (n = 10 in each group).Rats in model group were injected intraperitoneally with homocysteine (Hcy,200 mg · kg-1 · d-1) daily and were injected subcutaneously every other day with monosodium glutamate (MSG,1 g · kg-1 · 48 h-1) from the 10th day of pregnancy to establish the model of preeclampsia. Lowdose folic acid (low dose group 10 ng · kg-1· d-1) and high-dose folic acid (high dose group 20 mg · kg-1 · d-1 ) were given intragastric administration with folic acid tablets dissolved in saline daily at the same time of establishing model.Rats in control group were injected or intragastric administration with the same dose of saline as above up to the 20th day of pregnancy.Brain tissue was fixed on the 20th day of pregnancy, so was that plasma folic acid was measured with automatic electro-chemiluminescence.Rats' immunohistochemical staining.bcl-2 mRNA and protein expression changes were observed by using reverse transcription(RT) -PCR and western blot.Results ( 1 ) Plasma folate concentrations were ( 39.5 ± 3.4 )nmol/L in low dose group and (40.1 ±5.4) nmol/L in high dose group, which were all significantly higher than (26.9 ± 6.7 ) nmol/L in model group( P ＜ 0.01 ).Plasma folate in low dose and high dose group did not show significant difference( P ＞ 0.05 ); ( 2 ) Apoptosis cell were 48.2 ± 9.1 in low dose group and 44.7 ±8.3 in high dose group, which were significantly lower than 75.8 ± 10.1 in model group (P＜0.01).However, apoptosis cell in low dose and high dose group did not show significant difference( P ＞0.05 ) ;(3 )significant difference( P ＞ 0.05 ); (4) bcl-2 mRNA and protein expression were 0.98 ± 0.49 and 0.89 ±0.52 in low dose group and 0.95 ± 0.38 and 0.92 ± 0.47 in high dose group which was significantly higher than 0.62 ± 0.20 and 0.45 ± 0.37 in model group ( P ＜ 0.01 ); bcl-2 expression in low dose and high dose group showed no significant difference ( P ＞ 0.05 ).Conclusions Folic acid has a protective role on neural activation and promoting bcl-2 gene and protein expression.

AIM: To evaluate the changes of microRNA (miRNA) in hepatocytes during hydrogen peroxide-induced oxidative stress injury, and to observe the alleviating effect of mesenchymal stem cell-conditioned medium (MSC-CM) in this progress.METHODS: The hepatocyte oxidative stress injury model was established using hydrogen peroxide and human normal liver cell line L02.MSC-CM was prepared using centrifugation and filter.The effects of MSC-CM on hepatocyte injury were evaluated by apoptosis analysis, cell viability detection, cell cycle, and mitochondrial membrane po-tential (MMP).Twenty-one differentially expressed miRNAs were selected by gene chip hybridization, in which miR-143, miR-145, miR-301a and let-7a were confirmed by RT-qPCR.Bioinformatics software was utilized to predict target proteins of these miRNAs, and then the proteins were verified by Western blot.RESULTS: MSC-CM markedly attenuated hydrogen peroxide-induced oxidative stress injury by reducing apoptosis, promoting cell viability and regulating cell cycle.The ex-pression of miR-143, miR-145, miR-301a and let-7a, indentified by RT-qPCR, increased under the condition of oxidative stress injury, while decreased after MSC-CM treatment.The expression of miR-143 predicted target proteins, HK2 and ADRB1, decreased under the hydrogen peroxide-exposure, while increased after MSC-CM treatment, which is consistent with the regulatory trend of miR-143.CONCLUSION: MSC-CM might attenuate hydrogen peroxide induced oxidative stress injury via inhibiting apoptosis and regulating some miRNA expression.

Abstract?AlM:To investigate the effects of the MUC5AC levels and ocular function of the patients with glaucoma and cataract with combined surgery.? METHODS: Twenty - eight patients treated with glaucoma and cataract combined surgery were chosen as the observation group from December 2011 to June 2014 in our hospital, and other 28 cases of glaucoma and cataract did not undergo surgical treatment were selected as the control group, 30 healthy subjects were as healthy control group. the MUC5AC level and ocular surface score of the three subjects before surgery 1d, after 3 and 6mo were compared.?RESULTS: The NUC5AC of the two groups of patients was significantly lower than that of the healthy control group before surgery (P<0. 05), the ocular function score was significantly higher than the healthy control group ( P<0. 05). After 1mo, the MUC5AC of the observation group were significantly lower than that of before surgery ( P<0. 05), after 3mo MUC5AC content gradually increased to preoperative levels, after 6mo the MUC5AC were significantly higher than before surgery (P<0. 05). After 1mo, ocular function scores were significantly higher than the preoperative ( P< 0. 05 ), while after 3mo, ocular function scores decreased after 6mo of ocular surface function scores were significantly lower than the preoperative (P<0. 05). While the control group after 6mo, with the passage of time, the MUC5AC content gradually reduce, ocular function score increased gradually. ?CONCLUSlON:To treat the patients with glaucoma and cataract with combined surgery, the level of MUC5AC can temporary decrease. Ocular function score can temporary increase in, but after 3mo, it can be gradually improved.

4 weeks of arrested embryos.The AAH expression was found to have the similar result as HIF-1?'s.Conclusions The expression level of HIF-1? and AAH in villi of missed abortion patients is much lower than that of normal early pregnant women.HIF-1? and AAH have a function of supporting normal pregnancy,so their low expression may be an important cause of missed abortion.
