Objective To investigate the mierotechnique of bilayer amniotic membrane transplantation for treatment of Mooren's ulcer and evaluate the efficacy. Methods Six patients (6 eyes) with Mooren's ulcer were recruited for this study. After medical treatment or lameilar keratoplasty failed to arrest progress of corneal ulcer, bilayer amniotic membrane transplantation was performed for the treatment. We investigated the integrity of corneal epithelium, the healing of corneal ulcer, the improvement of stromal edema, the atrophy of neovessels, the transformation of amniotic membrane and the occurrence of relapse. Results All patients were followed up for 24-34 months (mean 30 months). In all cases, superficial anmiotic membrane dissolved or shed on postoperative day 7-11, disconnecting now. Corneal ulcer healed within 7-15 days postoperatively. In 5 eyes, corneal stromal edema faded away within 2-3 weeks. Corneal neovessels regressed within 2-3 months. The deeper grafts were adhered into the ulcer and fused with the cornea 3 months after the operation. Corneal transparence or macula was achieved within 5-8 months. No recurrence of Moorcn's ulcer was oc-curred in 4 patients during the follow-up period, while 2 eyes relapsed for the exposure of sutures and not re-moving the stitches timely, which had been treated with lamellar keratoplasty and no recurrence again during the follow-up period. Conclusion Bilayer amniotic membrane transplantation has advantages for Mooren's ulcer treatment. Mastering the microsurgical techniques and removing the stitches timely are the key to the success of surgery. It also provides good conditions for the further conduct of keratoplasty.

Objective To observe the effect of neutralizing monoclonal antibodies to antiglomerular basement membrane (GBM) antibody on anti-GBM nephritis rats. Methods Wistar rats were randomly divided into five groups: control group Ⅰ was a negative control and was injected with healthy human IgG via the caudal vein. Control group Ⅱ was injected with neutralizing monoclonal antibodies to anti-GBM antibody only. Anti- GBM nephritis group was injected with human anti-GBM antibody via the caudal vein only. Intervention group Ⅰ was injected with human anti-GBM antibody via the caudal vein and then with neutralizing monoclonal antibodies to anti-GBM antibody at day 7. Intervention group Ⅱ was injected with human antiGBM antibody via the caudal vein and then with neutralizing monoclonal antibodies to anti-GBM antibody at day 14. The blood, urine and kidney tissue were collected at day 7, 14, 21 for analysis of 24-hour urinary protein, BUN, Ser and histological study. Results At day 21, there were significant decreases in intervention group Ⅰ compared with anti-GBM nephritis group in 24-hour proteinuria [(16.62±5.53) g], BUN[(11.53±2.26) mmol/L] and Scr [(102.46±16.86) μmol/L] (P＜0.05), and also in intervention group Ⅱ as compared to anti-GBM nephritis group, but no significant difference was found (P＞0.05) . There was obvious decrease of renal cell proliferation,crescent formation and deposition of immune complexes in intervention group Ⅰ and intervention group Ⅱ compared with anti-GBM nephritis group, while such improvement in intervention group Ⅰ was more significant. There was no significant change in control group Ⅰ and control group Ⅱ.Conclusion The early application of neutralizing monoclonal antibodies to anti-GBM antibodies can effectively improve the kidney lesions of anti-GBM nephritis rats.

Objective To investigate ING2 expression in normal gastric tissue,gastric carcinoma and precancerous lesions, and to explore correlation between ING2 expression and the carcinogenesis and progression of gastric carcinoma and the clinicopathological signficance as well as the correlation between ING2 and raP53 protein. Methods The expression of ING2 was measured by PV9000 two-step immunohistochemical staining. In total, 188 gastric cancer(GC), 128 matched normal gastric mucosa,35 chronic atrophic gastritis (CAG), 87 intestinal metaplasia (IM) and 36 dysplasia (DYS) samples were analyzed. Expression of mP53 was measured in 40 samples from the 188 gastric carcinomas mentioned above. Results Positive ING2 expression was significantly more frequent in CAG (74.29%) ,IM (91.95%) ,DYS (75.0%) and GCs (70.21%) than in normal gastric mucosa (36.72% ,P ＜0.05). Among GCs, ING2 expression varied by Lanren's classification. A significantly higher rate of positive ING2 expression was observed in intestinal type GCs (80. 56%) than in diffuse (64.49%) and mixed (55.56%, P ＜ 0.05) type GCs. Furthermore, positive ING2 expression was significantly more frequent in well-to-moderately differentiated adenocarcinoma(80. 60%) than in poorly differentiated adenocarcinoma (62. 62%, P ＜ 0. 05). No correlation was found between ING2 expression and mP53 expression in GC (P ＞ 0. 05). Over-expression and mislocalization of ING2 may be involved in the development of CC, especially intestinal-type GC. Further investigations are needed to explore the relevant molecular mechanism.

OBJECTIVETo observe the effect of sodium tanshinone II (A) sulfonate (STS) on Ang II -induced atrial fibroblast collagen synthesis and TGF-beta1 activation.

METHODAtrial fibroblasts of neonatal rats were cultured to determine the content of collagen protein. The original synthesis rate determined by the [3H]-proline incorporation method was taken as the index for myocardial fibrosis. The content of active TGF-beta1 and total TGF-beta1 in cell culture supernatants were tested and cultured by ELISA. The expression of thrombospondin-1 (TSP-1) was assessed by using Western blot.

RESULTAng II could significantly increase the content of atrial fibroblast collagen and the collagen synthesis rate, the TSP-1 expression and the concentration of active TGF-beta1, without any obvious change in total TGF-beta1. After the STS treatment, all of the indexes, apart from total TGF-beta1, were obviously down-regulated.

CONCLUSIONSTS could decrease the secretion of Ang II -induced atrial fibroblast collagen and the synthesis rate. Its mechanism is related to the inhibition of TSP-1/TGF-beta1 pathway.

Currently, bacterial resistance situation in health care settings is very serious in China, and the prevalence of a variety of common multidrug-resistant bacteria and pan-resistant bacteria are relatively high. Drug-resistant bacteria in Gram-positive bacteria are mainly methicillin resistant Staphylococcus aureus ( MRSA ) and macrolide-resistant Streptococcus, while glycopeptide-resistant enterococci are still at a low level.The clonal distribution of MRSA and mechanisms of Streptococcus resistance in China are different from those in European and American countries.Cephalosporins and quinolones resistance are the marked characteristic of Enterobacteriaceae with a high occurrence over 60%. Carbapenem-resistant Klebsiella pneumoniae shows a rapid upward trend, and producing KPC-2 type carbapenemases is the main mechanism of its resistance.Resistance in Pseudomonas aeruginosa is relatively stable, with resistant rates ranging from 20%to 30%.Multi-drug resistant Acinetobacter baumannii is a big problem in clinic.More than 50% Acinetobacter baumannii strains are resistant to carbapenems and cephalosporins, and tigecycline-resistant Acinetobacter baumannii is increasing.This paper systematically reviews the status and characteristics of bacterial resistance in last five years with referring to the surveillance data of antimicrobial resistance and the findings of related mechanisms.
