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

Objectire To identify specific biomarkers that could improve early diagnsis of lung adenuearcinoma using matrix-assisted laser desorptian/ionization (MALDI) technology. Methods Serum samples were isolated from 17 patients with stage I lung adenuearcinoma and 17 age- and sex-matched healthy controls, and the serum proteomic profiles were obtained by matrix-assistcd laser desorption ionization time of flight (MALDI-TOF) mass spectrometry. Results Compared with healthy control group, two highly expressed potential biomarkers were identified with the relative molecular weights of 6 631.64 Da and 4 964. 21 Da. The two best novel protein peaks were automatically chosen for the system training and the development of the constructed model. The constructed model was then used to test an independent set of masked serum samples from 15 lung adenocarcinoma patients and 22 healthy individuals. The analysis yielded a sensitivity of 93.3 %, and a specificity of 95.5 %. Conclusion These results suggest that MALDI-TOF-MS ProteinChip technology is a quick, convenient, and high-output analyzing method that is capable of selecting several relatively potential biomarkers from the serum of lung adenocarcinoma patients and may have a clinical value in the future, and will provide clues to identifying new serologic btomarkers of lung adenocarcinoma.

Objective To understand the life quality of elderly person in communities, nursing homes and elderly wards, and to find out the related influencing factors for providing references for policy-makers to improve the life quality of the elderly. Methods The senior citizens in 9 communities, 3 villages, 12 nursing homes and 5 elderly wards in Shanghai Minhang District were enrolled by stratified cluster sampling. And the life quality and its influential factors among the inhabitants in communities, nursing homes and elderly wards were compared by adopting Short-Form 36 (SF-36) questionnaire. Results Regarding to the life qualities of senior citizens, community showed that physical functioning was (71. 9 ± 23. 3)scores, role physical was (73. 6 ± 43. 0) scores, bodily pain was (80. 2±20. 3)scores, general health was (53. 2± 19. 1)scores, vitality was (70. 4± 15. 7)scores, social function was ( 83. 8 ± 20. 2) scores, role emotional was ( 81. 1 ± 37. 2 ) scores, mental health was (78. 1 ± 15. 4) scores, weighted average was (74. 1 ± 17. 5) scores. Nursing home showed that physical functioning was (42. 1 ±30. 7) scores, role physical was (57. 9 ±48. 1) scores, bodily pain was (78.0±23.0)scores, general health was (50. 2± 19. 5)scores, vitality was (66. 0± 19. 5)scores, social function was (70. 8 ± 26. 3) scores, role emotional was (66. 8 ± 45. 7) scores, mental health was (73. 6 ± 19. 6) scores, weighted average was (63. 2 ± 21. 0) scores. Elderly ward showed that physical functioning was (20. 4 ± 26. 0) scores, role physical was (36. 1 ± 47. 0) scores, bodily pain was (65. 4±29. 5)scores, general health was (43. 1±17. 1)scores, vitality was (59. 0± 18. 0)scores, social function was (57. 9 ± 25. 3) scores, role emotional was (49. 5 ± 48. 7) scores, mental health was (66. 2 ± 18. 3) scores, weighted average was (49. 7 ±18. 3) scores. The major influential factors on the life quality were gender, education, marriage, profession, age, disease, residence, entertainment, physical exercise for community; Age, disease, residence, entertainment, physical exercise for nursing home; Age, etc for elderly ward. Conclusions The influences of demographic factors on life quality of the senior citizens in communities are more significant than in nursing home and elderly wards. Variations on the degree of satisfaction (in residence, entertainment, health care and transportation) and the situation of physical exercise have made vast difference in the life quality of the senior citizens both in communities and nursing homes.

Objective:To test the effects of propofol on intracellular calcium free concentration ([Ca~(2+)]i) and inositol 1,4,5-triphosphate (IP_3) biological synthesis induced by norepinephrine (NE) and 5-hydroxytryptamine (5-HT) in aortic smooth muscle cells (ASMC)of rats for the mechanism of relaxtion of propofol on vascular smooth muscle.Method: Using the flurospectrophotometry and Fura-2/AM loading method,the changes of [Ca~(2+)]i levels in primary culture ASMC were measured,and using the specific, IP_3 assay system and isotope radioactive protein binding experiment IP_3 production levels in aortic smooth muscle were measured. Result:The baselines of [Ca~(2+)]i was decreased when primary culture ASMC was pretreated with propofol in 72 hours. Propofol inhibited [Ca~(2+)]i increase induced by NE and 5-HT in dose-dependent way. With extracellular calcium free or calcium channel blocker(Verapamil),inhibition of propofol on NE and 5-HT increasing [Ca~(2+)]i levels were decreased,but could not be cancelled. Propofol depressed IP_3 biological synthesis induced by NE and 5-HT in dose-dependent way. Conclusion:Relaxation of propofol on aortic smooth muscle is closely related to inhibiting IP_3- induced calcium release to decrease intracellular calcium concentration.
