Objective To investigate the effects of prone position on functional residual capacity (FRC) , pulmonary gas exchange and hemodynamics in mechanically ventilated patients with acute lung injury (ALI) .Methods Eight patients (6 male, 2 female) aged 29-61 yr who developed ALI with PaO2/FiO2

Objective To investigate the effects of obesity on functional residual capacity ( FRC ) , ventilatory function and gas exchange during and after cholecystectomy. Methods Twenty ASA Ⅰ or Ⅱ patients of both sex aged 26-58yr undergoing elective cholecystectomy were divided into 2 groups according to the body mass index (BMI): control group BMI 30 (n = 10) . The patients were premedicated with intramuscular luminal 1.0 g and atropine 0.5 mg. Anesthesia was induced with midazolam 2-3 mg, fentanyl 5?g?*kg-1, propofol 1.5-2.0 mg?kg and vecuronium 0.1 mg?kg-1 and maintained with infusion of propofol (at 8-10 mg?kg-1?h-1) and fentanyl (at 1-2 ?g?kg-1?h-1) and intermittent i.v. boluses of vecuronium after tracheal intubation. The patients were mechanically ventilated (VT 10ml?kg-1,I:E=1:2, FiO2 100%) and PETCO2 was maintained at 35-40 mm Hg by adjusting the respiratory rate. Pethidine 1 mg?kg-1 was given i.m. every 8 h after operation for analgesia. BP, HR, ECG, SpO2, PET CO2 , FiO2, VT , RR were monitored during anesthesia. Arterial blood samples were taken before anesthesia (T0, baseline), 15 min after induction of anesthesia (T1), 30 min after skin incision (T2) and 6, 24 h after operation (T3,4) for blood gas analysis. FRC (closed-circuit helium dilution method), forced vital capacity (FVC), forced expiratory volume at 1 second (FEV10) and maximal mid-expiratory flow volume (MMF) were measured before and 6 h and 24 h after operation.Results FRC was significantly decreased after induction of anesthesia, during and after operation compared with the baseline value (T0) in both groups and the decrease in FRC was significantly larger in obesity group than in control group (P

Objective To investigate the effects of inhaled aerosolized low dose ambroxol on the inflammatory response to one-lung ventilation (OLV) in patients undergoing open-chest esophagus surgery.Methods Sixty patients (aged 39-64 years,weighing 50-85 kg and with height of 153-181 cm) with normal heart and lung function undergoing open-chest esophagus surgery were randomly divided into three groups:20 patients receiving intravenous infusion of normal saline (control group,group C),20 receiving intravenous infusion of ambroxol 10 mg/kg after induction of anesthesia (group IA) and 20 inhaling aerosolized ambroxol 30 mg after induction of anesthesia (group AIA).Arterial blood samples were taken after induction of anesthesia before ambroxol administration (T0,baseline),after 90 minutes of OLV (T1) and at 30 minutes after OLV (T2) for determination of plasma concentrations of tumor necrosis factor-alpha (TNF-α),interleukin-1 beta (IL-1β),IL-8 and IL-10 by enzyme linked immunosorbent assay (ELISA).Results The levels of TNF-α,IL-1β,and IL-8 in plasma significantly increased while the level of IL-10 in plasma significantly decreased at T1 and T2 as compared with the baseline at T0 in all the three groups.The levels of TNF-α,IL-1β,and IL-8 in plasma were significantly lower and the level of IL-10 in plasma was significantly higher at T1 and T2 in groups IA and AIA than in group C.Conclusion Both intravenous injection of large dose ambroxol and inhaled aerosolized low dose ambroxol can inhibit the inflammatory response to OLV in patients undergoing open-chest esophagus surgery.

Objective To investigate the effects of inhaled aerosolized low dose ambroxol on the inflammatory response to one-lung ventilation ( OLV) in patients undergoing open-chest esophagus surgery. Methods Sixty patients with normal heart and lung function undergoing open-chest esophagus surgery were randomly divided into 3 groups ( n = 20 each): control group (group C) ; group IA received Ⅳ ambroxol 10 mg/kg after induction of anesthesia and group AIA inhaled aerosolized ambroxol 30 mg after induction of anesthesia. Arterial blood samples were taken after induction of anesthesia before ambroxol administration (T0, baseline) , at 90 min of OLV (T1 )and at 30 min after OLV (T2) for determination of plasma concentrations of TNF-α, IL-1β, IL-8 and IL-10 by ELBA.Results Plasma TNF-α, IL-1β, and IL-8 concentrations were significantly increased while plasma IL-10 concentration was significantly decreased at T1 and T2 as compared with the baseline at T0 in all 3 groups. Plasma TNF-α, IL-1β, and IL-8 concentrations were significantly lower and plasma IL-10 concentration was significantly higher at T1 and T2 in groups IA and AIA than in group C. Conclusion Both Ⅳ large dose ambroxol and inhaled aerosolized low dose ambroxol can inhibit the inflammatory response to OLV in patients undergoing open-chest esophagus surgery.

ObjectiveTo evaluate the effect of increasing doses of tamsulosin in lower urinary tract symptom (LUTS) of benign prostatic hyperplasia (BPH).MethodsA prospective self-controlled clinical trail was performed.Two hundred and sixty-one patients who had LUTS of BPH were enrolled in this prospective 4 weeks study of tamsulosin.The patients were randomly divided into 2 groups:took tamsulosin 0.2 mg QN (n =126,group A) and 0.4 mg QN (n =135,group B) respectively.The IPSS score and maximum flow rate before and after treatment were compared between the 2 groups.ResultsThe IPSS score of group A decreased from 17.72 ± 2.50 to 10.21± 1.95,average decreased 7.59 ± 2.74 ； maximum flow rate was elevated from (8.78 ± 3.70) ml/s to ( 12.74 ± 2.99 ) ml/s,average increased (4.31 ± 3.01 )ml/s.The IPSS score of group B decreased from 19.24 ± 3.22 to 11.21 ± 3.02,average decreased 8.49 ±3.73； maximum flow rate was elevated from (7.74 ± 1.97) ml/s to ( 12.04 ± 2.46) ml/s,average increased (4.73 ± 2.97) ml/s.There was no significant difference of the changes of IPSS score between the 2 groups ( P ＞ 0.05 ),but there was a significant difference of the changes of maximum flow rate between the 2 groups ( P ＜ 0.05 ).The results was further analyzed by sub grouped ( by patient body weight,divided into ≤55.0 kg,55.1 -65.0 kg,65.1 -75.0 kg,＞75.0 kg group).There were significant differences of the changes of IPSS score and maximum flow rate between the 2 groups in 65.1 - 75.0 kg and ＞ 75.0 kg subgroups ( P ＜ 0.05 ).The incidence of side effects between the 2 groups was not significantly different (P ＞ 0.05).ConclusionsFor most patients,the use of high-dose tamsulosin in improving LUTS caused by BPH can not bring significant benefits.But if the patient's weight is more than 65.0 kg,increasing the dose of tamsulosin is suggested for consideration.

AIM: To study the synergistic protective effect of picrosideII and NGF for the oxidative stress on PC12 cells induced by hydrogen peroxide (H2O2). METHODS: The fluorescent probe 6-carboxy-2',7'-dichlorodihydrofluorescein (CDCFH) was used to assess the intracellular reactiveoxygen species (ROS) level, and MTT assay, morphological observation as well aslactate dehydrogenase (LDH) leakage were conducted to measure cellular injury. RESULTS: The H2O2-induced cytotoxicity was significantly attenuated in the presence of picroside II (25 μg/mL) and NGF (2 ng/mL). Cultures with this combined treatment possessed decreased level of ROS while increased cell survival, as compared to that of picroside II or NGF alone-treated cells. Accordingly, it was concluded that their synergistic protective activities against oxidative stress in vitro were demonstrated in various aspects including reversing morphological changes, enhancingthe ability of cell proliferation and ROS scavenging. CONCLUSION: Such action supports the therapeutic potential of picroside II and NGF in treating nervous disorders based on their synergistic effect.

Objective To evaluate the clinical characteristics, surgical treatment effect and prognostic factors of post-operative hypertension in the 2 subtypes of primary aldosteronism (PHA),aldosterone adenoma (APA) and unilateral adrenal hyperplasia (UNAH). Methods In the collection of surgical treatment of PHA from 2002-2009, 135 cases, 68 males and 67 females, with age of 26-79 years (mean, 51 years) were analyzed. Of them, there were 83 APA patients, 52 UNAH cases. All the cases with PHA were with hypertension symptoms and met the preoperative diagnosis criteria. All the patients were performed preoperatively blood biochemical and hormonal tests and CT scans. The diagnosis was confirmed by pathology. All cases undergone adrenal reserved surgery (ASS) and followed-up. According to the postoperative recovery of blood pressure was normal or still in hypertension, Logistic regression analysis and comparison between the 2 groups were carried out,the clinical data of various factors in predicting the role of postoperative blood pressure were considered. Results One hundred and thirty-five patients were operated successfully. The mean follow up was 2. 5± 1.6 years (1-7 years). There were significant decreases in both systolic blood pressure and diastolic blood pressure at final follow up compared with those before surgery. Antihypertensive requirement was decreased at final follow-up. Serum aldosterone levels, plasma renin activity and potassium levels were improved significantly. Overall, blood pressure returned to normal in 51 cases(37.8%). Other 84 cases (62.2%) continued with high blood pressure, of whom 58 cases reduced antihypertensive drug use. Patient's age over 49.5 years, hypertension duration over 6. 5 years, family history of hypertension were higher risks of postoperative continuous high blood pressure. Conclusions APA and UNAH are 2 types of PHA with similar performance of patients, surgical treatment effect. ASS can be used in the treatment of these 2 types of disease. Age, hypertension duration, family history of hypertension are independent factors predicting sustained hypertension after surgery.

OBJECTIVE:To prospectively study the effects of entecavir combined with Silymarin on the inflammatory markers and oxidative stress level in patients with hepatitis B virus-related decompensated liver cirrhosis (HBV-DLC).METHODS:A total of 85 HBV-DLC patients in Hospital of Wuhan Technology University during Jan.2015-Aug.2016 were divided into control group (42 cases) and observation group (43 cases) according to the single and double number random.Control group was given entecavir 0.5 mg,qd.Observation group was additionally given Silymarin capsules 140 mg,tid,on the basis of control group.Both groups were treated for 48 weeks.After treatment,HBV DNA and HBeAg negative conversion rate were observed.The levels of liver function indexes (TBil,AST,ALT),the Child-pugh score and levels of inflammatory indexes (IL-18,IL-8,TNF-α),the levels of oxidative stress indexes (MDA,SOD,NO) were compared between 2 groups before and after treatment.The occurrence of ADR was recorded.RESULTS:Before treatment,there was no statistical significance in liver function indexes,inflammatory factors or oxidative stress indexes of 2 groups (P＞0.05).After treatment for 48 weeks,serum HBV DNA and HBeAg negative conversion rate of observation group were higher than those of control group,but without statistical significance (P＞0.05).Compared with before treatment,liver function indexes levels,Child-pugh score,inflammatory indexes,MDA and NO levels of 2 groups were decreased significantly after treatment for 48 weeks (P＜0.05),while SOD level was decreased significantly (P＜0.05);the degree of improvement of above indexes in observation group was higher than control group (P＜0.05).There was no statistical significance in the incidence of ADR between control group and observation group (P＞0.05),and both were improved after drug withdrawal.CONCLUSIONS:Entecavir combined with Silymarin can inhibit inflammatory reaction and relieve oxidative stress reaction to improve the liver function of HBV-DLC patients;drug combination better than entecavir alone.
