Objective To investigate the effects of peroral endoscopic myotomy (POEM) on esophageal dynamics in patients with achalasia (AC) and appraise the role of high resolution manometry (HRM)in assessment of POEM therapy.Methods From July 2011 to September 2012,20 patients with achalasia underwent POEM in the department of gastroenterology,Tianjin Medical University General Hospital.Preoperation esophageal dynamics of all the patients were evaluated by high resolution manometry (HRM) system and one month after POEM operation the test was repeated.Data of lower esophageal sphincter (LES)and esophageal body were analyzed,with 15 healthy volunteers as a contrast study.Results Mter POEM,the LES pressure (LESP) and 4-second integrated relaxation pressure (4sIRP) significantly decreased:LESP [pre-operation (24.5 ± 13.1) mm Hg vs.post-operation (8.5 ± 3.1) mm Hg,P ＜ 0.05] ; 4sIRP [pre-operation (20.7 ± 6.8) mm Hg vs.post-operation (5.0 ± 3.4) mm Hg,P ＜ 0.05].The LES relax rate (LESRR) significantly elevated [pre-operation (12.7 ± 9.8) ％ vs.post-operation (39.6 ± 18.1) ％,P ＜ 0.05].However,the esophageal aperistalsis remained after POEM.The total of 20 patiems were all type Ⅰ achalasia and responded well to POEM therapy.Post-operation data on the symptom scores markedly decreased and a significant correlation was found between the decreasing level of symptom scores and LESP,as well as the scores 4sIRP in the 20 patients (LESP:r =0.751,P ＜ 0.05 ; 4sIRP:r =0.500,P ＜ 0.05).Conclusion POEM can significantly improve esophageal dynamics in patients with achalasia and the treatment outcome is definite.HRM plays an important role in evaluation of POEM therapy on achalasia.

BACKGROUND: It is indicated in researches of recent years that both astragalus and angelica act on anti-free radical and protect renal injury due to ischemia / reperfusion.OBJECTIVE: To observe the protection and its mechanism of astragalus and angelica injections on adenosine triphosphate-ase (ATPase) in renal injury due to ischemia/reperfusion.DESIGN: The observing controlled experiment based on experimental animals .SETTING: Physiological teaching & research room and teaching & research room of renal functional protection in a medical college. MATERIALS: The experiment was performed in Physiological Experimental Room of Luzhou Medical College from January 2001 to March 2001. Totally 33 Japanese big-ear white healthy adult rabbits of either sex were employed,provided by Experimental Animal Center of Luzhou Medical College, in the mass of(1.63 + 0. 22) kg. According to random number table, they were divided in sham-operation control(8 rabbits), simple ischemia/reperfusion group (8 rabbits), astragalus injection + ischemia/reperfusion group (astragalus group) (8 rabbits) and angelica injection + ischemia/reperfusion group(angelica group) (9 rabbits).METHODS: One day before operation, on the day of operation and 1 day after operation, successively, intravenous medical injections (astragalus 1.25 g/kg,angelica 12.5 g/kg) were administrated in astragalus and angelica groups everyday respectively, and injection with physiological saline 5 mL/kg was applied in the control and simple ischemia/reperfusion group. In 48 hours reperfusion after 1 hour ischemia in kidney, blood sample was collected from inferior vena cava. The upper tissue of the right kidney was collected and fixed by placed in 30 mL/L glutaraldehyde and the lower tissue was prepared into homogenate. Ultrastructure of renal tissue was examined with electron microscope; serum creatinine level and ATPase activity in renal tissue were assayed.MAIN OUTCOME MEASURES: Ultrastructure of renal tissue, serum creatinine level and ATPase activity in renal tissue.RESULTS: In simple ischemia/reperfusion group, renal tissue was degenerated significantly, and the disorders in astragalus and angelica groups were reduced markedly compared with simple ischemia/reperfusion group. Serum creatinine level in simple ischemia/reperfusion group was higher remarkably than the sham-operation control ( P ＜ 0. 05 ), and that in astragalus and angelica groups was reduced than simple ischemia/reperfusion group (P ＜ 0. 05) . In simple ischemia/reperfusion group, the levels of Mg2+-ATPaes, Na+-K+-ATPase and Ca2+-ATPase were(0. 155 ±0. 020),(0.179±0.018), (0.150±0.022) nkat/g respectively, which was markedly reduced compared with sham-operation control [ (0. 174 + 0. 012),(0. 198 + 0. 012), (0. 181 + 0. 017) nkat/g], ( t = 2. 344, 2. 438, 3. 014,P ＜ 0.05 ). In astragalus and angelica groups, respectively, the activities of Mg2+-ATPaes, Na+-K+-ATPase and Ca2+-ATPase were(0. 172 ± 0. 023),(0. 196 ±0. 077), (0. 175 ±0. 016) and (0. 177 ±0. 015), (0. 200 ±0.011 )and (0. 181 ± 0. 025) nkat/g successively. Except that Mg2+-ATPaes activity in astragalus group was not different significantly from that in simple ischemia/reperfusion group, all the rest were higher than simple ischemia/reperfusion group(t =2. 372 -2. 786, P ＜0.05).CONCLUSION: Both astragalus and angelica inhibit the decrease of ATPase and improve the disturbed local blood-flow adjustment in kidney, which has provided experimental basis of astragalus and angelica on reducing renal injury induced by ischemia/reperfusion through protecting ATPase.

To study the expression of transforming growth factor β1 (TGFβ1) and platelet-derived growth factor (PDGF) in alveolar type Ⅱ cells and their significance in the process of pulmonary fibrosis. MethodsCultivation of alveolar type Ⅱ cells were mode from normal adult rat and of silicotic animal model of rat was established. In situ hybridization and irnmunohistochemieal staining were applied to detect the gene expression of TGFβ1 and PDGF-B in the alveolar type Ⅱ cells of primary culture and silicotic tissue. Results(1) In situ hybridization and immunohistochemical staining showed the positive expression of TGFβi, PDGF-B rnRNAs and their relevant proteins in cultured alveolar type Ⅱ cells. (2) The positive expression of TGFβ1, PDGF-B rnRNAs and their proteins were prominent in the proliferative alveolar type Ⅱ cells of experimental group of silicotic models. Weak expression of TGFβ1 mRNA were found only in a part of normal alveolar type Ⅱ cells of control group. ConclusionThe proliferative alveolar type Ⅱ cells express TGFβ1 and PDGF-B, which may play an important role in silicotic fibrcsis.
