AIM: To explore the effects of high glucose a t fluctuant concentrations on glucose transport activity and expression of phosp hoinositide 3-kinase (p85) in primary cultured skeletal muscle cells. ME T HODS: Rat skeletal muscle cells were cultured at fluctuant glucose conce ntrations (5, 25mmol/L) for 48h. Then the glucose uptake and the expression of p hosphoinositude 3-kinase were measured. RESULTS: The skeletal mu s cle cells treated with fluctuant high concentration glucose showed the impairmen t of the basal and insulin-induced increase in glucose uptake and significant de crease in p85 protein expression as well as p85 mRNA. Particularly, there was a significant decrease in p85 protein and mRNA expression in the high fluctuate l evel of glucose concentration. CONCLUSION: The exposure to fluct uant high concentration of glucose inhibits glucose uptake and induces insulin r esistance in skeletal muscle cells.

Objective To investigate the advantages, indications and efficiency of video-assited thoraco-scopic sugery in spontaneous pneumothorax. Methods 31 patients with spontaneous pneumothorax underwent video-assited thoracoscopic sugery, performed with endoscopic manual suture without use of endoscopic cutters. Results All patients were cured without recurrence. Conclusions Video-assited thoracoscopic sugery is the first choice in treating spontaneous pneumothorax,with minimal trauma,less bleeding. Endoscopic manual suture can obviously re-duce the treatment cost.

Objective To explore the curative effect and patient's tolerance combined transcatheter arterial chemoembolization(TACE) and three dimensional conformal radiotherapy(3DCRT) for primary hepatocellular carcinoma.Methods 38 patients were treated by combined TACE and 3DCRT.The treatment regimen consisted of TACE first,it took TACE of Doxombicin 50 mg/m2,Fluorouracil 600 mg/m2,Cisplatin 60 mg and iodine Oil 10~15 ml.repeated every four weeks.thlee times totally.After resting one or two months,followed by 3DCRT(44~56 Gy/7~11f/3~4w),the planning target volume(PTV)was covered by the 80%~90% isodose curve and the target dose was prescribed to PTV.Resuits All patients completed the planned treatment without interruption.Hematological and radiation-induced toxicities as shown by the WHO staging system were 52.6% of grade 1~2 acute gastrointestinal tract reaction and 47.4% of grade 1~2 bone marrow inhibition but they were tolerable.The complete response(CR)and partial response(PR)rates were 23.7% and 63.2%.respectively,with a CR+PR rate of 86.8%.The median survival was 18.5 months.The 1-,2-and 3-year survival rates were 73.7%,57.9% and 34.2% respectively. Conclusion Combined TACE and 3DCRT iS better to short-term curative effect,it has lesser toxicities and it is a satisfactory therapy for unreseetable primary hepatocellular carcinoma.Long-tem survival and late toxicities need further observation.

Objective To explore the effects of multidisciplinary comprehensive pulmonary rehabilitation on aged patients with pneumo-coniosis. Methods From January, 2012 to January, 2015, 85 old stable inpatients with pneumoconiosis were divided into control group (n=40) and rehabilitation group (n=45). Both groups accepted routine medicine, while the rehabilitation group received multidisciplinary com-prehensive pulmonary rehabilitation for twelve weeks. They were assessed with cardiopulmonary exercise test, BODE index and quality of life before and after treatment. Results The maximum work, maximal oxygen uptake, 6-minute walk distance, scores of modified Version of the British Medical Researsh Council Respiratory Questionnaire, BODE index, activities of daily living, social activities, depression and anx-iety improved in the rehabilitation group after treatment (t>3.379, P<0.01), and were better than those in the control group (t>2.201, P<0.05). No imporvement was found in all the indices in the control group after treatment (t<2.339, P>0.05). Conclusion Multidisciplinary comprehensive pulmonary rehabilitation can effectively improve exercise tolerance and quality of life in aged patients with pneumoconiosis.

Objective To investigate the effect of proteasome inhibitor MG132 on the proliferation of human lens epithelial cells SRA01/04. Methods The SRA01/04 cells were treated with MG132 by different concentrations (0, 0. 1, 0. 5, 1. 0, 2. 5, 5.0, 10. 0μmol/L) for 36 hours. The cell viability in all groups was determined using methylthiazoltetrazolium (MTT) test. The effect of MG132 on the apoptosis and regulation of cell cycle about SRA01/04 cells were detected by flow cytometry (FCM). The SRA01/04 cells treated with MG132 were observed after Annexin V/FITC-PI staining by fluorescence microscope. Results The inhibitory effect of MG132 on SRA01/04 cells proliferation was enhanced with the increase of MG132 concentration. The 50% inhibiting concentration ( IC50 ) of MG132 was 2. 50μmol/L after SRA01/04 cells were treated with MG132 for 36 hours. The apoptosis index of the cells treated by MG132 at 2. 5μmol/L and 5 μmol/L for 36 hours was 6. 55 ± 0. 35% and 13.75 ± 3.18%, and 0. 75 ± 0. 21% for 5.0μmol/L for 36 hours in control group. After cells were treated with MG132 for 48h, the percentages of cells at G0/G1 phase were (42. 57 ± 0. 64) %, (73.42 ± 3.10) %, ( 80. 95 ± 3.83 ) % 0, 2. 5,5.0 μmol/Lgroups respectively, and those at S phase were (49. 44±1.36)%, ( 17. 40 ± 1.50)%, ( 19. 57 ± 1.29)%.Annexin V/FITC-PI staining was used, and MG132 was found to result to apoptosis. Conclusions MG132 could inhibit the proliferation of SRA01/04 cells by the effect of inducing apoptosis and regulation of cell cycle. The proteasome inhibitor-might play a key role in the prevention of posterior capsular opacification.

Breathing gas carries important physiological information. Technology for detection of breathing gas has become a research focus because of the advantages of nondestructive sampling and convenient operation. Proton transfer reaction mass spectrometry (PTR-MS) plays an irreplaceable role because of the advantages of high sensitivity, fast response and good specificity. In this paper, the principle of PTR-MS is introduced first, followed by research progress of PTR-MS in the field of breathing gas detection. Factors influencing the test results are analyzed. Finally, future prospects of development for PTR-MS in the field of breathing gas detection are discussed.
