Objective To summarize the effect and experience of nursing of patients with rheumatic valvular heart disease with atrial fibrillation treated with Cox Ⅲ labyrinth and simultaneous valve replace-ment operation. Methods A retrospective analysis was carried out in the nursing of 58 patients with rheumatic valvular heart disease with atrial fibrillation treated with Cox Ⅲ labyrinth and simultaneous valve replacement operation in our hospital from April 2006 to July 2008. Results One patient died of periop-erative renal failure,one died of low cardiac output,one died of infectious endoearditis.Tbe mortality rate reached 5.2%.Other patients were discharged from hospital after completely cured.The survived patients maintained sinus rate during hospitalization days after operation and short-term follow-up after being dis-charged.Among 43 patients who completed follow-up of 6 months after operation,3 patients (7.0%) damon-strated atrial fibrillation,while others still kept sinus rate. Conclusions Attention should be paid to psy-chological nursing,respiratory tract preparation,cardiac function monitoring and nursing of anticoagulation treatment for patients treated with Cox Ⅲ labyrinth and simultaneous valve replacement operation.

AIM: To investigate the role of retinal pigment epithelium (RPE) in the growth of Müller cells using a co-culture system in vitro . METHODS: Müller cells were cocultured with RPE cells under both normoxic and hypoxic conditions in Transwell chamber culture system. Müller cell proliferation was evaluated by MTT assay. The number of cells which migrate through micropores and stay on the outer bottom side of insert systems were observed and counted. RESULTS: The activities of proliferation and migration of Müller cells when cocultured with RPE cells were significantly higher than those of the Müller cells when cultured alone at all time points under both normoxic and hypoxic conditions. However, for both the coculture and control groups, there is no significant difference between the measurements at 3 and 6 hours. CONCLUSION: Evidence suggests that RPE, when co-cultured with Müller cells, can stimulate migration and proliferation of Müller cells under both hypoxic and normoxic conditions in a time-dependent manner; how-ever, there is no evidence to support the synergetic interaction of RPE and Müller cells co-cultured under hypoxic conditions.

Objective To investigate the effects of ulinastatin on pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer. Methods The clinical data of 40 elderly patients with esophageal cancer who had been admitted to Southwest Hospital from January 2005 to January 2008 were retrospectively analyzed. All the patients were randomly divided into control group (n = 20) and ulinastatin group (n = 20) according to random number table. Patients were administered with total parenteral nutrition, and patients in ulinaslatin group were additionally instilled with 4×10~5 U/d of ulinastatin. The levels of PaO_2, PaCO_2, PaO_2/FiO_2, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Tbil), blood urea nitrogen, creatinine and uric acid were detected preoperatively and at postoperative day 2 and day 6. All the data were analyzed by t-test and chi-square test. Results The levels of PaO_2 and PaO_2/FiO_2 were (87.3±4.2) mm Hg (1 mm Hg =0.133 kPa) and (416±20)mm Hg in ulinastatin group, which were significantly higher than (79.0±4.3)mm Hg and (376±20)mm Hg in control group (t =6.2, 6.2, P <0.05). The levels of ALT, AST and Tbil were (23±7)U/L, (38±8)U/L and (13.4±3.0) μmol/L in ulinastatin group, and (39±8) U/L, (50±9) U/L and (24.5±6.0) μmol/L in control group, with significant difference between the 2 groups (t = 7.0, 4.4, 7.6, P < 0.05). The levels of uric acid, blood urea nitrogen and creatinine were (279±84) μmol/L, (4.1±1.7) mmol/L and (66±12) μmol/L in ulinastatin group, and (386±67)μmol/L, ( 8.9±2.7) mmol/L and (95±38) μmol/L in control group, with significant difference between the 2 groups (t = 4.4, 6.4, 3.3, P < 0.05). The recurrence of complications in ulinastatin group was significantly lower than that in control group (χ~2 = 4.8, P <0.05). Conclusion Postoperative supplementation of ulinastatin and total parenteral nutrition is helpful in improving the pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer.
