Objective To investigate the diagnostic value of trans-gastric peritoneoscopy with technique of natural orifice transluminal endoscopic surgery(NOTES)for tuberculosis peritonitis.Methods Clinical data of 20 patients with tuberculosis peritonitis diagnosed by trans-gastric peritoneoscopy via NOTES were retrospectively analyzed.Results All diagnoses were confirmed by biopsy.The findings of peritoneoscopy were defined as miliary type with miliary nodes scattered in ascites and on peritoneum,adhesive type with thickening of peritoneum and adhesion between peritoneum and intestines,cheese-like type with parietal peritoneal ulcer and cheese-like substances,and mixed type with 2 or 3 of above mentioned types.Positive findings in other laboratory examinations were hemoglobin decrease in 10(50％)patients,blood sedimentation rate increase in 16(80％),C reactive protein increase in 13(65％),CA125 increase in 18(90％),and positive tuberculin test in 9(45％).Abnormal findings were detected by chest X-ray in 8(40％)patients,by abdominal ultrasonography examination in 2(10％),by abdominal CT in 7(35％),and by colonoscopy in 1(5％).No abnormal results were found in all patients in anti-tuberculosis antibody test,ascites bacteria culture and gastroscopy.Conclusion Trans-gastric peritoneoscopy via NOTES with biopsy is effective for diagnosis of tuberculosis peritonitis.

Objective To evaluate the role of autophagy in hydrogen-induced reduction of lung injury in septic mice.Methods Sixty pathogen-free healthy male ICR mice,aged 6 weeks,weighing 20-25 g,were divided into 5 groups (n =12 each) using a random number table:sham operation group (group Sh),sepsis group (group Sep),sepsis plus hydrogen group (group Sep+H2),sepsis plus autophagy inhibitor 3-methyladenine (3-MA) group (group Sep+3-MA) and sepsis plus 3-MA plus hydrogen group (group Sep+3-MA+H2).Sepsis was produced by cecal ligation and puncture.At 1 h before operation,3-MA 10 mg/kg was intraperitoneally injected.The mice inhaled 2％ H2 for 1 h starting from 1 and 6 h after operation.Blood samples were collected from the common carotid artery at 24 h after operation for measurement of arterial oxygen partial pressure,and the oxygenation index (OI) was calculated.Pulmonary specimens were obtained for examination of the pathological changes which were scored.Pulnonary mitochondria were isolated for determination of mitochondrial membrane potential (MMP) and ATP content using fluorescence spectrophotometry and a bioluminescence assay,respectively,and the respiratory control rate (RCR) was calculated.The expression of autophagy-related protein microtubule-associated protein 1 light chain 3 (LC3) was determined by Western blot,and the ratio of LC3-Ⅱ to LC3-Ⅰ expression (LC3-Ⅱ/LC3-Ⅰ ratio) was calculated.Results Compared with group Sh,the pathological scores were significantly increased,the OI and contents of mitochondrial RCR,MMP and ATP were decreased,and the LC3-Ⅱ/LC3-Ⅰ ratio was increased in Sep and Sep+H2 groups (P＜0.05).Compared with group Sep,the pathological scores were significantly decreased,the OI and contents of mitochondrial RCR,MMP and ATP were increased,and the LC3-Ⅱ/LC3-Ⅰ ratio was increased in group Sep+H2,and the pathological scores were significantly increased,the OI and contents of mitochondrial RCR,MMP and ATP were decreased,and the LC3-Ⅱ/LC3-Ⅰ ratio was decreased in group Sep+3-MA (P＜0.05),and no significant change was found in each parameter mentioned above in group Sep+3-MA+H2 (P＞0.05).Compared with group Sep+H2,the pathological scores were significantly increased,the OI and contents of mitochondrial RCR,MMP and ATP were decreased,and the LC3-Ⅱ/LC3-Ⅰ ratio was decreased in group Sep+3-MA+H2 (P＜0.05).Conclusion The mechanism by which hydrogen ameliorates lung injury is related to enhanced level of autophagy in septic mice.

Objective To investigate the effect of umbilical cord blood dendritic cells(DCs)induced by gastric cancer antigen combined with cytokine induced killer(CIK)cells in gastric cancer cell lines SGC-7901 in vitro. Methods Mononuclear cells from umbilical cord blood were used to create DCs and CIKs. The cell surface antigen expression of the mature DCs such as CD83,CD86,CD11c and the cell surface antigen of CIKs such as CD3,CD56,CD4,CD8,CD16 were detected using flow cytometry. Sensitized DCs-CIKs,DCs-CIKs,CIKs as effective cells,and SGC-7901 as target cells,the killing activities of these effective cells were tested with LDH release,which the number ratio of cells between effective cells and SGC-7901 cells were 10 :1,20 : 1,40 : 1,respectively. Results The cell surface antigen expressions of the mature DCs,such as CD83 + CD86 + ,CD11c + CD83 + ,CD86 + CD11c + were(75. 4 ± 2. 1)% ,(79. 3 ± 1. 4)% ,(80. 2 ± 2. 6)% , respectively. The mature sensitive-DCs surface antigen expressions,such as CD83 + CD86 + ,CD11c + CD83 + , CD86 + CD11c + ,were(77. 7 ± 1. 5)% ,(82. 6 ± 1. 9)% ,(76. 9 ± 2. 6)% ,respectively. There was no sta-tistical significance about the surface antigen expression between DCs and sensitive-DCs(t = 1. 526,P ﹥ 0. 05;t = 0. 958,P ﹥ 0. 05;t = 1. 049,P ﹥ 0. 05). The CIKs surface antigen expressions,such as CD4 + ,CD8 + , CD3 + CD56 + CD16 + ,were(22. 8 ± 1. 3)% ,(77. 3 ± 1. 8)% ,(24. 5 ± 2. 1)% ,respectively. The results suggested that the killing effect of the three kinds of combination cells on gastric cancer cells was different. The number ratio of cells between sensitive-DCs and SGC-7901 cells were 10 : 1,20 : 1,40 : 1,which the killing activities of sensitive-DCs-CIKs against SGC-7901 were(37. 68 ± 1. 49)% ,(41. 67 ± 0. 90)% ,(42. 71 ± 0. 98)% ,respectively. The killing activity of sensitive-DCs-CIKs was the highest when the ratio of cells between sensitive-DCs and SGC-7901 cells were 40 : 1. The killing activities of DC-CIKs were(36. 77 ± 0. 46)% ,(38. 94 ± 0. 95)% ,(41. 15 ± 0. 89)% ,respectively. The killing activities of CIKs were(34. 74 ± 1. 01)% ,(37. 76 ± 0. 43)% ,(39. 65 ± 0. 79)% ,respectively. There were statistically significant differences among the three groups(F = 5. 92,P ﹤ 0. 05;F = 19. 13,P ﹤ 0. 05;F = 8. 88,P ﹤ 0. 05). Conclusion The tumor killing activity of CIK is enhanced obviously by umbilical cord blood DCs which is sensitized by gastric cancer tumor antigen. There is the highest killing activity when the number ratio of cells between sensitive-DC-CIK and SGC-7901 cells is 40 : 1.

Aim To investigate the effect that catalpol intervenes macrophage polarization mediated by mouse mesangial cells(MMCs) stimulated by advanced glycation end products(AGEs).Methods RAW264.7 macrophages and MMCs were co-cultured in vitro and divided into model group(100 mg·L-1 AGEs), control group(100 mg·L-1 BSA), catalpol(0.1, 1.0, 10.0 μmol·L-1) group, and aminoguanidine(1.0 μmol·L-1) group which was set as positive control.After being incubated with catalpol for 1 h, MMCs were stimulated by AGEs for 23 h.The proliferation-inhibition rate of MMCs was measured by MTT assay.MCP-1 in supernatant liquid of MMCs was detected by ELISA method.The expression of iNOS, CD16/32, TNF-α, COX-2, CD206 and Arg-1 was detected by Western blot.Simultaneously, the percentage of iNOS and CD206 was also measured by flow cytometry.Results AGEs could increase the level of MCP-1 secreted by MMCs.The expression of iNOS, TNF-α, CD16/32 and COX-2 protein of macrophage was up-regulated after MMCs stimulated by AGEs, while the expression of CD206 and Arg-1 was down-regulated.After being intervened by catalpol, these effects could be reversed.All the changes were concentration-related.Conclusions Catalpol can inhibit macrophages M1-type polarization process and promote M2-type polarization, which may be mediated through MCP-1 secreted by MMCs after AGEs stimulation.Catalpol can ameliorate inflammation and relieve diabetic kidney injury.
