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.

To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.

Objective To approach the effect of protective mechanical ventilation on acute lung injury after orthotopic liver transplantation, by observing changes of plasma markers of lung injury and inflammatory mediators.Methods Sixty patients scheduled for liver transplantation under general anesthesia, 42 males and 18 females, aged 21-62 years, weighing 43-80 kg, ASA physical status Ⅱ-Ⅳ, were randomly divided into 2 groups: protective mechanical ventilation group (group P) and unprotective mechanical ventilation group (group U).Pulmonary artery blood for plasma markers of lung injury and inflammatory mediators were collected at the following time points: before operation (T1), 3 hours after mechanical ventilation (T2), 2 hours (T3) and 4 hours in neohepatic stage (T4).These mediators included clara cell secretory protein (CC16), surfactant proteins (SP-D), soluble receptor for advanced glycation end-products (sRAGE), TNF-α, IL-6 and IL-8.Moreover, blood gas results were recorded at these 7 time points: T1-T4, 2 hours after operation (T5), before tracheal extubation (T6) and 2 days after operation (T7).The postoperative awakening time, tracheal extubation time, ICU stay time and the incidence of ALI were recorded.Results Compared with T1, plasma level of CC16 in the two groups increased at T2 and T3 (P<0.05 or P<0.01), however, plasma level of SP-D, sRAGE, TNF-α, IL-6 and IL-8 did not increase until T3 (P<0.01).Moreover, plasma level of sRAGE, TNF-α, IL-6 and IL-8 at T4 were higher than those at T1 (P<0.05 or P<0.01).Compared with T1, OIs in the two groups increased at T2, T5 and T6 (P<0.05 or P<0.01), while decreased at T4 in group P (P<0.01) and at T3 and T4 in group U (P<0.01).In group P, patients showed a lower plasma level of CC16 at T2 and T3 (P<0.05 or P<0.01), a higher OI at T3 (P<0.05) and an earlier tracheal extubation after operation [(8.9±3.2) h vs (9.3±2.8) h, P<0.05] compared with group U.There was no significant difference of acute lung injury incidence between the two groups after operation, which was 5(16.6%) and 7 (23.3%), respectively.Conclusion Protective mechanical ventilation may promote oxygenation index, and shorten tracheal extubation time, thus protect lung function of patients in liver transplantation to some extend.

Objective To evaluate the effects of lung-protective ventilation on acute lung injury after liver transplantation.Methods Sixty patients of both sexes,aged 21-64 yr,with body mass index of 18-28 kg/m2,of American Society of Anesthesiologists physical status Ⅱ-Ⅳ,scheduled for elective orthotopic liver transplantation,were divided into 2 groups (n =30 each) using a random number table:conventional mechanical ventilation group (group CMV) and lung-protective ventilation group (group LPV).In group LPV,the patients were mechanically ventilated (tidal volume 6-8 ml/kg,respiratory rate 10-15 breaths/min,positive end-expiratory pressure 3-10 cmH2 O),and lung recruitment mnaneuver was pertormed every 2 h.Before skin incision (T1),at 3 h of preanhepatic phase (T2),at 30 min of anhepatic phase (T3) and at 2 and 4 h of neohepatic phase (T4.5),bronchoalveolar lavage fluid (BALF) was collected and blood samples from the radial artery were simultaneously collected for determination of tumor necrosis factor-alpha and interleukin-8 concentrations in BALF and serum by enzyme-linked immunosorbent assay.At 2 h after operation (T6),before tracheal extubation (T7) and at 2 days after operation (T8),blood samples from the radial artery were collected for blood gas analysis,and oxygenation index was calculated.The concentrations of serum Clara cell secretory protein 16,surfactant protein D and soluble receptor for advanced glycation end-products were determined at T1-T8 using enzyme-linked immunosorbent assay.The postoperative emergence time,extubation time,duration of intensive care unit stay and development of acute lung injury were recorded.Results Compared with group CMV,the cxtubation time was significantly shortened,serum concentrations of Clara cell secretory protein 16 at T2,T3,T6 and T7,serum surfactant protein D concentrations at T5 and serum concentrations of soluable receptor for advanced glycation endproducts at T5 and T6 were decreased (P＜0.05),and no significant change was found in tunor necrosis factor-alpha and interleukin-8 concentrations in serum and BALF at each time point or postoperative incidence of acute lung injury,oxygenation index,emergence time and duration of intensive care unit stay in group LPV (P＞0.05).Conclusion Although lung-protective ventilation dose not decrease the development of acute lung injury after liver transplantation,it attenuates lung tissue injury to some extent.

Background Our previous study demonstrated that epigallocateehin-gallate(EGCG),an active ingredient of green tea,has protective effect on optical nerve after optic nerve crush.Astrocyte was proved to play key role in the repair of nerve tissue,but the influence of EGCG on astrocyte is unclear.Glial flbrillary acidic protein (GFAP) is a special marker for astrocyte. Objective The aim of this study was to investigate the effect of EGCG on the expression of GFAP in optic nerve tissue after optic nerve crush. Methods Seventy-two clean Wistar rats were randomly divided into normal control group,sham+EGCG group,optic nerve crush+normal saline group(vehicle group),optic nerve crush+EGCG group.Optic nerve crush models were established by clamping optical nerve for 60 seconds by minitype optic nerve clipper with the force of 40 gram.Only ocular tissue was cut in the rats in sham group.Normal saline solution or EGCG(25 mg/kg)was intraperitoneally injected daily for 5 days consecutively and orally administered(2 mg/kg)daily afterwards.The expression of GFAP in optic nerve was detected by immunohistochemistry and quantified by Western blotting analysis on day 7,14 and 28 after modeling. Results lmmunochemistry showed that GFAP were weakly expressed in the rats of both normal group and sham+EGCG group with the sliSht brown staining in optic nerve tissue.The deeply brown staining for GFAP was seen in vehicle group,and the staining intensity weakened in optic nerve crush+EGCG group compared to vehicle group on days 7,14 and 28 after modeling.Western blotting analysis revealed that the expression level of GFAP in rat optic nerve tissue of vehicle group was significantly enhanced in comparison with normal control group(P＜0.01).On day 7 and 14 after optic nerve modeling,the expression levels of GFAP were evidently decreased in optic nerve crush+EGCG group in comparison with vehicle group(P＜0.05).However,on day 28 after modeling,no significant difference wag found in the expression levels of GFAP between vehicle group and optic nerve erush+EGCG group(P＞0.05). Conclusion EGCG down-regulates optic nerve crush-induced of GFAP in the optic nerve and therefore attenuates the activity of astrocytes,suggesting that EGCG might reduce the formation of glial scar.
