OBJECTIVETo evaluate the effect of electro-acupuncture (EA) on gastric mucosal oxygenation and systemic inflammatory response in patients undergoing endoscopic sinus surgery with controlled hypotension (CH), and to explore its protective effect on gastric mucosa.
METHODSFifty-four patients, 18-65 years old, grade I-II of American Society of Anesthesiology (ASA), who were scheduled for endoscopic sinus surgery were randomly assigned to two groups, group A (general anesthesia group) and group B (general anesthesia combined EA anesthesia group), 27 in each group. Conrolled hypotension was executed during operation, and mean arterial pressure (MAP) was maintained at 55-65 mmHg. After tracheal intubation gastric tesiometer catheter was indwelled through nasal cavity or oral cavity. After successful indwelling, it was connected with gastric mucosa monitoring mode of multifunctional parameters monitor. Patients' MAP and heart rate (HR), pHi, partial pressure of carbon dioxide (PgCO2), arterial partial pressure of carbon dioxide (Pg-aCO2) and endtidal pressure of carbon dioxide (Pg-etCO2) were measured and recorded at T, (immediately before induced hypotension), T, (20 min following induced hypotension to target MAP), T2 (40 min following induced hypotension to target MAP), T3 (20 min after ending induced hypotension), and T4(40 min after ending induced hypotension). Blood samples were intravenously collected, TNF-alpha, IL-1, and IL-6 were detected by ELISA 24 h before operation, during operation (T3), and 24 h after operation.
RESULTSAfter hypotension was induced, Pg-CO2, Pg-aCO2 and Pg-etCO2 increased significantly (P < 0.01, P < 0.05), while pHi decreased significantly (P < 0.01) in both groups at T1-T4 than those at T0. During T1-T4, PgCO2, Pg-aCO2, and Pg-etCO2 were higher (P < 0.01, P < 0.05), while pHi was lower in group A than in group B (P < 0.01). Furthermore, TNF-alpha, IL-1, and IL-6 increased significantly in both groups during operation and 24 h after operation, when compared with those 24 h before operation (P < 0.01, P < 0.05). TNF-alpha and IL-1 in group A were higher than those in group B (P < 0.05) during operation and 24 h after operation, but with no significant difference in the plasma concentration of IL-6 (P > 0.05).
CONCLUSIONEA exerted obvious protective effect of gastric mucosal injury in endoscopic sinus surgery with controlled hypotension, which might be achieved by increasing gastric mucosal blood flow, maintaining oxygen supply and demand, inhibiting inflammatory response, and alleviating injury of gastric mucosal barrier.

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 assess left ventricular (LV) global systolic function in patients with essential hypertension with normal geometric LV by 3-dimensional ultrasound speckle tracking imaging(3D-STI). Methods Fifty patients with essential hypertension were enrolled in this study, 29 normal subjects matched with age and sex were selected as control groups. LV global longitudinal peak systolic strain (GLS), radial peak systolic strain (GRS), circumferential peak systolic strain (GCS), LV global 3-dimentional radial peak systolic strain (3DGRS) were measured in all subjects by 3D-STI from the apical full-volume image and compared between groups. LV ejection fraction (LVEF) was acquired from 3D-STI.Results Compared with controls, LV GLS, GRS, GCS and 3DGRS were significantly reduced in patients with hypertension ( P < 0.05 for all). A Pearson correlate revealed that LV GCS, GLS and GRS corresponded with LVEF( r1 =0.930, P1 <0.001; r2 = 0.705, P2 <0.001; r3 =0.474, P3 =0.001,respectively) in patients with hypertension, and LV GCS, GLS correlated with LVEF( r1 = 0. 838, P1 <0. 001; r2 = 0. 697, P2 < 0. 001, respectively) in normal subjects. Conclusions LV global 3D strain decreases in patients with hypertension in the early period,3D-STI could evaluate the early change of heart function in patients with hypertension. LV circumferential movement plays a major role in the LV 3D movement and impacts on LVEF.
