ABSTRACT
Objective To explore the damage of spiral ganglion neurons(SGNs),the protective effects of different dosages of healthy ear compound (HEC)from traditional Chinese medicine(TCM) against age-induced SGNs degeneration and its possible mechanism in spiral ganglion neurons(SGNs)of C57BL/6J mice.Methods Totally 36 C57BL/6J mice just after ablactation were randomly divided into four groups.Normal control group (n =6)drank tap water daily from ablactation to 2 months old.Ageing-related SGNs apoptosis control group(n=12)drank tap water daily from ablactation to 7 months old.High dose TCM group(n=12)at drank 3.65 g/kg/d of HEC from ablactation to 7 months old.Low dose TCM group(n=6)drank 0.91 g/kg/d of HEC from ablactation to 7 months old.The animal cochleae were immediately removed at the termination of the experiment.In each group,the cochleae of 6 animals were used for paraffin embedding,slicing and toluidine blue staining to observe neuronal morphological changes.The caspase-3 mRNA expression study was performed by real-time PCR technique in 6 cochleae of High dose TCM group and ageing-related SGNs apoptosis control group.Results The morphological structure of cochlear SGNs represented healthy and normal density in normal control group at 2 months old.In contrast,amount or density of SGNs in cochlear basilar part was significantly damaged and reduced in ageing-related SGNs apoptosis control group at 7 months old(P＜ 0.001).But the high dose TCM group at 7 months of age was similar to the normal control group at 2 months old in morphological structure,amount or density of SGNs(P＞0.05).The low dose TCM group was significantly different from other 3 groups in amount or density of SGNs (P＜0.001).However,SGNs in the middle part and apical part showed integrity in each group.In addition,the expression level of caspase-3 in the cochlea of high dose TCM group was also obviously different with age-related SGNs apoptosis control group(P＜0.01) Conclusions Ageing-related damage of SGNs in C57BL/6J mice begins from the base of cochlea and progresses towards the apex.The HEC of TCM could significantly protect SGNs against age-induced apoptosis in SGNs.The efficacy of the high dose TCM is better than that of the low dose TCM.Its SGNs protective mechanisms might be related to involving the caspase-mediated cell apoptotic pathway.

ABSTRACT
Objective To investigate the effect of different levels of positive pressure (PEEP) during one-lung ventilation on blood gas and hemodynamics in patients with thoracoscopic lung bullae resection surgery.Methods Seventy-eight patients undergoing thoracoscopic lung bullae resection surgery were divided into three groups by random number table method,26 cases in each:group Ⅰ was only given one-lung intermittent positive pressure ventilation (IPPV) after two-lung ventilation,group Ⅱ was given one-lung IPPV and PEEP 5 cmH2O (1 cmH2O =0.098 kPa) after two-lung ventilation,group Ⅲ was given one-lung IPPV and PEEP 10 cmH2O after two-lung ventilation.Blood gas and hemodynamics were recorded and compared in the supine position and lateral position two-lung ventilation,one lung ventilation 10 and 30 min among three groups.Results Oxygen saturation was maintained at 0.99-1.00 in three groups.pH value,base excess,arterial carbondioxide partial pressure (PaCO2) and HCO3-at each time point in three groups had no statistical significance (P ＞ 0.05).Arterial oxygen partial pressure (PaO2) in group Ⅱ and group Ⅲ at one-lung ventilation 10,30 min was significantly higher than that in group Ⅰ [(336.2 ± 113.2),(348.5 ± 109.7) mmHg (1 mmHg =0.133 kPa) vs.(285.0 ± 103.5) mmHg,(357.6 ± 104.0),(358.9 ±103.2) mmHg vs.(276.0 ± 107.2) mmHg] (P ＜0.05),but were within the normal range,there was no statistical difference between group Ⅱ and group Ⅲ (p ＞ 0.05).Heart rate,mean arterial pressure,left ventricular ejection time,systemic vascular resistance at each time point in three groups had no statistical significance (P ＞0.05).Stroke volume,cardiac output in group Ⅱ and group Ⅲ at one-lung ventilation 10,30 min were lower than those in supine position and lateral position two-lung ventilation and the same period in group Ⅰ (P ＜ 0.05),but were within the normal range,there were no statistical differences between group Ⅱ and group Ⅲ (p ＞ 0.05).Conclusions Two-lung ventilation after one-lung IPPV and PEEP 5 cmH2O in thoracoscopic lung bullae resection surgery can maintain satisfactory PaO2 and PaCO2,hemodynamic change is not obvious; PEEP 5 cmH2O compares with only IPPV can further improve PaO2,but PEEP 10 cmH20 can't further improve PaO2.
ABSTRACT
<p><b>OBJECTIVE</b>To detect hFgl2 expression in peripheral blood mononuclear cells in patients with chronic hepatitis B and liver cancer and explore its association with the severity of chronic hepatitis B.</p><p><b>METHODS</b>The protein expression of hFgl2 in peripheral blood mononuclear cells was detected in 78 patients with chronic hepatitis B (including mild, moderate, or severe cases), chronic severe hepatitis, or liver cancer, with 20 healthy volunteers as controls. The data were analyzed in comparison with the patients' alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBiL and) levels.</p><p><b>RESULTS</b>hFgl2 protein expression was significantly higher in patients with chronic severe hepatitis and liver cancer than in the healthy volunteers and patients with chronic hepatitis B. The patients with chronic severe hepatitis had significantly higher hFgl2 protein expression than patients with liver cancer. In severe cases of chronic hepatitis B, hFgl2 protein expression was positively correlated with ALT, AST and TBiL, but these correlations were not found in mild or moderate cases.</p><p><b>CONCLUSIONS</b>Peripheral blood mononuclear cells express hFgl2 protein, whose expression level increases with the severity of chronic hepatitis B.</p>
