Résumé
POEMS syndrome is a rare clinical disease associated with plasma cell diseases.Classic pentalogy includes: multiple peripheral neuropathy, organ enlargement, endocrine disorders, M-proteinemia and skin lesions.Due to its rarity, multiple system involvement and high clinical heterogeneity, the missed diagnosis rate and misdiagnosis rate are high.This paper reports a case of M protein negative POEMS syndrome with ascites as the prominent manifestation.

Objective To investigate the effect of intravenous anesthesia with sufentanil combined with propofol on hemodynamics and oxygen metabolism in patients with esophageal cancer under high altitude.Methods 60 patients with esophageal cancer radical surgery was selected from March 2015 to March 2017 in our hospital and were divided into two groups according to the random number table,30 patients in each group.Patients in the control group were given with fentanyl and propofol intravenous anesthesia,and patients in the observation group were given sufentanil combined with propofol anesthesia.The occurrence of restlessness during the recovery of anesthesia in the two groups were observed,the spontaneous breathing recovery time,extubation time and postoperative Mini-mental State Examination (MMSE) score were recorded,and the indexes of hemodynamics and oxygen metabolism were measured at the time of before induction of anesthesia (T0),tracheal intubation (T1),skin incision (T2),thoracotomy (T3),free esophagus (T4),esophageal catheter removal time (T5).Results The spontaneous respiration recovery time and extubation time of the observation group were significantly shorter than those of the control group (P ＜ 0.05).The degree of restlessness in the observation group was weaker than that in the control group (P ＜ 0.05).Mean arterial pressure (MAP) in the control group at T2-T4 were significantly higher than those in T0 (P ＜ 0.05),but MAP and heart rate (HR) in the observation group at T1-T5 were significantly lower than those of T0 (P ＜ 0.05).Compared with T0 group,oxygen saturation (SpO2),oxygen saturation of mixed venose blood (SvO2) and oxygen delivery (DO2) at T1-T5 were significantly decreased (P ＜ 0.05),oxygen consumption (VO2) at T2-T4 was significantly increased (P ＜ 0.05),especially in the control group (P ＜ 0.05).The MMSE scores of the two groups were significantly lower than those before the operation (P ＜ 0.05),and the scores in observation group was significantly higher than the control group (P ＜ 0.05).Conclusions The intravenous anesthesia with sufentanil combined with propofol is more helpful in maintaining hemodynamic stability and oxygen metabolism balance than intravenous anesthesia with fentanyl combined with propofol and has little effect on postoperative anesthesia recovery and cognitive function.
Résumé
Objective To explore the efficacy of autologous pleural patch in surgical operation on the patient with chronic tuberculous empyema.Methods Autologous pleura patches were used to repair the pulmonary wound in the surgical operations for 7 patients with chronic tuberculous empyema,who received surgical management in Hebei Provincial Chest Hospital from August 2012 to November 2014.The leak time of the patient and the time of the chest tube were recorded,the pulmonary re-examination was observed by chest X-ray,and the follow-up results were recorded.Results The time of persistent pulmonary air leak of 6 patients was not more than 10 hours after operation,1 patient was not more than 24 hours.Review of X-ray chest showed that good for lung,4-7 d after operation removal of thoracic dosed drainage tube,there was no death and no chest infection in 7 patients and review of CT chest showed no significant residual cavity.After follow-up for 6-24 months 7 patients had satisfactory efficacy,there was no pneumothorax and thoracic infection,no residual cavily.Conclusion Autologous pleura can be used to patch the pulmonary wound in the surgical operation on the patient with chronic tuberculous empyema.

Objective To investigate the expression patterns and significance of aquaporin 5 (AQP‐5) and multidrug‐resistance associated genes in human colon cancer with different differentiation degree and their correlation .Methods The expression of aqua‐porin 5 and resistance genes P‐gp ,GST‐π,TopoⅡ ,and TS in human 45 cases colon cancer tissues with different differentiation de‐gree and 36 cases of adjacent mucosa tissues as well as 58 cases of normal colonic epithelium were detected by quantitative RT‐PCR ,Western blot and immunohistochemistry .Results Immunohistochemistry results showed that AQP‐5 distributed mainly in the cell membrane and the cytoplasm .Fluorescence quantitative RT‐PCR and Western blot showed that AQP‐5 expression could not be detected in adjacent mucosa tissues and normal colonic epithelium tissues .The AQP‐5 expression level was higher in colon cancer tissues compared with adjacent mucosa tissues and normal colonic epithelium tissues (P0 .05) .Positive correlation was found between the expression of AQP‐5 and P‐gp ,GST‐π,Topo Ⅱ(P0 .05) .Conclusion The AQP‐5 and re‐sistance gene expression were increased in colon cancer tissues .The AQP‐5 expression level was higher in colon cancer compared with adjacent control or normal tissues ,which may promote the transfer and progress of colon cancer .

Résumé
Objective To investigate the relationship between maternal serum lipid levels and newborn weight in pregnant women with single positive diabetic screening test. Methods On the basis of 75 g oral glucose tolerance test (OGTT), 406 pregnant women during 24-28 gestational week whose 50 glucose challenge test (GCT)≥7.8 mmol/L were separated to gestational diabetes mellitus (GDM) group with 115cases, gestational impaired glucose tolerant (GIGT) group with 60 cases,and GCT (+) group with 231 cases.The serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol(LDL-C), apolipoprotein A1 (ApoA1) and apolipoprotein B (ApoB) were measured at the same time. Results Serum TG concentration was significantly higher in GDM group than that in GIGT group and GCT(+) group(P＜0.01).The level of HDL-C, ApoB in GDM group were lower than those in GIGT group and GCT(+) group (P＜0.01). In the 231 women with positive diabetic screening but normal glucose tolerance who delivered at term, the incidence of macrosomia was significantly higher in those with TG levels higher than 3.5 mmol/L (25.0%, 11/44) than in mothers who TG levels were lower than 3.5mmol/L (11.2%, 21/187) (P=0.017). Multiple regression analysis (stepwise) showed that the independent risk factors of macrosomia was the level of TG and ApoB (F=7.677,P=0.006;F = 7.842,P = 0.001 ).Conclusion Among pregnant women with single positive diabetic screening test,maternal serum TG and ApoB are independently associated with neonatal birth weight.

Résumé
AIM: To explore the effects of aflatoxin G 1(AFG 1 )on proliferation and TNF-? secretion of human peripheral blood mononuclear cells(HPBM) in vitro. METHODS: The effects of AFG 1 on proliferation of HPBM were analysed with flow cytometric (FCM) DNA analysis and MTT bioassay, while that on TNF-? secretion was detected with ELISA. RESULTS: FCM analysis revealed that 6 h after treatment, proliferation index(PI) of 1000 ?g/L AFG 1 treated HPBM was significantly higher than that of control. 24 h after AFG 1 treatment, stimulating effects on proliferation was found in HPBM treated with AFG 1 at 200 ?g/L and 1 000 ?g/L.Regression analysis showed that PI was postively correlated with the concentrations of AFG 1 in the concentration range from 0 to 1 000 ?g/L( r=0. 5122 and 0.5119 respectively,P
