AIM:To evaluate the effects of pilocarpine, brinzolamide and the preservatives of them on corneal epithelial cells and the histopathology of rabbit conjunctiva. METHODS: Fifteen New Zealand white rabbits weighing 1.5 kg to 2.5 kg were randomly divided into three groups. One group with three rabbits served as untreated controls. Pilocarpine 1% and brinzolamide 1% each were administered to the right eyes in one treated group, and the preservatives (chlorobutanol 0.01% in pilocarpine, benzalkonium chloride 0.01% in brinzolamide) to the left eyes. Corneal epithelial damage was evaluated by scanning electron microscopy, and conjunctival specimens were examined under light microscopy. RESULTS: Compared with normal controls, brinzolamide and BAC caused corneal epithelium damage and increased number of inflammatory cells in the conjunctiva, while pilocarpine and the preservative chlorobutanol mainly influenced the corneal epithelium. Brinzolamide produced significantly more damage than pilocarpine (P

Objective:To explore the promoting effects of IL-7 and IL-2 on CD4+CD25-T cells proliferation in vitro and construct a stable culture system in vitro for CD 4+CD25+regulatory T cells from human umbilical cord blood.To compare the inhibiting effects between induced proliferated CD 4+CD25+Tregs and naturally isolated CD 4+CD25+Tregs on PBMCs functional activity.Methods:CD4+CD25-T cells and CD4+CD25+T cells were isolated from human umbilical cord blood mononuclear cells by magnetic activated cell sorting ( MACS) system and then expanded in vitro.Four different concentration levels of IL-7 combined with proper concentration of IL-2 were added as inducer and the efficiency and optimal concentration of IL-7 on inducing,CD4+CD25-T cells were analyzed via 4 different methods.Flow cytometry method was used to detect the changes of CD 4+CD25-T cells.The inhibitory effect of expanded CD 4+CD25+T cells on peripheral blood mononuclear cells (PBMCs) was tested by MTS.The expressions of Foxp3,IL-10 and TGF-βgenes in CD4+CD25+T cells were test by RT-PCR.Results:The CD4+CD25+T cells from each groups were expanded significantly after three weeks of culture.The results indicated that use of IL-7 combined with IL-2 resulted in the highest cell expansion comparing to the other groups.It was shown by the inhibitory test that the expanded CD 4+CD25+regulatory T cells could inhibit the proliferation of PBMCs ,but IL-7 induced CD4+CD25+regulatory T cells exerted weaker suppressor activity than natural regulatory T cells .Only IL-7 (4 ng/ml) and IL-2 (2 000 U/ml) induced CD4+CD25+regulatory T cells showed the strongest killing activity.Conclusion:We successfully expand CD4+CD25+regulatory T cells in vitro.The protocol is established in which the use of mAbCD 3/CD28 combined with IL-7 and IL-2 resulted in the highest cell expansion ,and intensely expressed cell phenotype of CD 4 and CD25.

OBJECTIVESTo study perioperative inflammatory response status in patients with acute aortic dissection. To analyze the reason and outcome of the inflammatory activation.

METHODSBetween August 2011 and December 2011, 30 patients (22 male and 8 female, mean aged (43 ± 9) years) had undergone open repairs of aortic dissection or aneurysm with deep hypothermic circulatory arrest. Indications for surgical intervention were type A aortic dissection in 26 patients and aortic aneurysm in 4 patients. In detail, ascending aorta and arch replacement combined with stent elephant trunk were done in 29 patients, arch replacement combined with stent elephant trunk in 1 patient. According to the time from clinical onset of the dissection to operation, acute group (less than 7 days, group A) 20 patients, chronic group (more than 30 days and aortic aneurysm, group C) 10 patients. White blood cell, C-reactive protein and procalcitonin were assayed before and after operation. These valuables were recorded and compared statistically between two groups.

RESULTSThere were no significant differences in age, operation time, and blood transfusion volume (P > 0.05). Preoperative serum level of inflammatory indicators in group A were significant higher than in group C (t > 3, P < 0.05). Postoperative serum peak level of these indicators were significant higher than preoperative level in both groups (t > 4, P < 0.05). There were much more complications occurred on patients in group A (21 cases) than in group C (0 cases). The occurrence of early postoperative complications in group A was much higher than group C (χ(2) = 12.209, P = 0.000). Mechanic ventilation time in group A and group C were (35 ± 58) hours and (18 ± 9) hours respectively. ICU length of stay in two group were (49 ± 61) hours and (33 ± 12) hours, respectively. The patients with mechanic ventilation time more than 24 h, ICU length of stay more than 5 days in group A was more than in group C significantly (χ(2) = 5.161, P = 0.010; χ(2) = 3.657, P = 0.024).

CONCLUSIONSAcute aortic dissection and surgical procedure induce an acute phase inflammatory reaction. The patients with acute aortic dissection involved more serious organic injury and worse outcome following surgery compared with chronic aortic dissection.

Objective To investigate the effect of trabeculectomy combined with segmental iridectomy, mitomycin C (MMC) and viscoelastic agents usage on the treatment of glaucoma secondary in uveitis. Methods According to the age, degree of inflammation and the condition of Tenon capsule of patients, differ-ent concentration of MMC (0.25-0.33 mg/ml) was used during the operation, with separation of the anterior and posterior synechia, resection of pupillary organization membrane using viscoelastic agents. Segmental iridec-tomy and releasable sutures were also performed on the patients. The visual acuity of preoperation and postoper-ation, intraocular pressure, inflammation and the complication were record. Results Forty-two eyes of 38 cases with glaucoma secondary in uveitis were studied, the mean follow-up time was (12.01±3.56) months. The postoperative visual acuity improved in 14 eyes, didn't change in 28 eyes. The postoperative inflammation of anterior chamber disappeared in 35 eyes, relieved in 7 eyes. And the average postoperative intraocular pres-sure (15.20± 4.64) mmHg was significantly lower than the preoperative intraocular pressure (38.37±12.93) mmHg (t = 8.255, P = 0.000). The total success rate was 92.9%. There were no severe complication. Conclusion Trabeculeetomy combined with MMC, viscoelastic agents usage, separation of anterior and poste-rior syneehia, segmental iridectomy and releasable suture could increase the success rate of operation on pa tients with glaucoma secondary in uveitis, decrease the complication and inflammation reaction of operation, and the recurrence of uveitis.

OBJECTIVETo study the effect of Zhusha Anshen pill, cinnabar, HgS, HgCl2 and MeHg on the gene expression of renal transporters in mice.

METHODHealthy male mice were given equivalent physiological saline, Zhusha Anshen pill (1.8 g · kg(-1), containing 0.17 g · kg(-1) of mercury), cinnabar (0.2 g · kg(-1), containing 1.7 g · kg(-1) of mercury), high dose cinnabar (2 g · kg(-1), containing 1.7 g · kg(-1) of mercury), HgS (0.2 g · kg(-1), containing 0.17 g · kg(-1) of mercury), HgCl2 (0.032 g · kg(-1), containing 0. 024 g · kg(-1) of mercury), MeHg (0.026 g · kg(-1), containing 0.024 g · kg(-1) of mercury), once daily, for 30 d, measuring body mass gain. 30 days later, the mice were sacrificed. The mercury accumulation in kidneys was detected with atomic fluorescence spectrometer. Expressions of Oat1, Oat2, Oat3, Mrp2, Mrp4, Urat1 were detected with RT-PCR.

RESULTCompared with the normal control group, a significant accumulation of Hg in kidney in HgCl2 and MeHg groups was observed (P <0.05), but these changes were not found in other groups. Compared with normal control group, mRNA expressions of Oat1 and Oat2 were evidently lower in HgCl2 and MeHg groups, but mRNA expressions of Mrp2 were apparently higher in HgCl2 group (P <0.05), mRNA expression of Mrp4 was significant higher in HgCl2 and MeHg groups, and mRNA expression of Urat1 was apparently lower in MeHg group.

CONCLUSIONHgCl2 and MeHg groups show significant difference from the normal group in mercury accumulation in kidneys and gene expression of kidney transporters, but with no difference between other groups and the normal group. Compared with HgCl2 and MeHg, cinnabar and its compounds could cause lower renal toxicity to mice.

Chloroplast-based expression system is promising for the hyper-expression of plant-derived recombinant therapeutic proteins and vaccines. To verify the feasibility of obtaining high-level expression of the SARS subunit vaccine and to provide a suitable plant-derived vaccine production platform against the severe acute respiratory syndrome coronavirus (SARS-CoV), a 193-amino acid fragment of SARS CoV spike protein receptor-binding domain (RBD), fused with the peptide vector cholera toxin B subunit (CTB), was expressed in tobacco chloroplasts. Codon-optimized CTB-RBD sequence was integrated into the chloroplast genome and homoplasmy was obtained, as confirmed by PCR and Southern blot analysis. Western blot showed expression of the recombinant fusion protein mostly in soluble monomeric form. Quantification of the recombinant fusion protein CTB-RBD was conducted by ELISA analysis from the transplastomic leaves at different developmental stages, attachment positions and time points in a day and the different expression levels of the CTB-RBD were observed with the highest expression of 10.2% total soluble protein obtained from mature transplastomic leaves. Taken together, our results demonstrate the feasibility of highly expressing SARS subunit vaccine RBD, indicating its potential in subsequent development of a plant-derived recombinant subunit vaccine and reagents production for antibody detection in SARS serological tests.
