Objective To analyze and discuss the negative effects of atomization inhalation in mechanical ventilation patients in intensive care unit. Methods A retrospective study of all the mechanical ventilation patients in the general ICU of our hospital was carried out from Aprilto December 2015. The risk of multidrug-resistant organisms(MDROs)colonizationin the lower respiratory tract and ventilation associated pneumonia(VAP)in mechanical ventilation patients were analyzed. Results A total of 922 patients were monitored, 160 of whom had atomization inhalation, 92 for MDROs colonizationin the lower respiratory tract and 18 for VAP. The rates ofatomization inhalation in patients with and without MDROs colonizationin the lower respiratory tract were 30.4%(28/92)and 15.9%(132/830)with statistical difference (χ2=12.193, P=0.000). And those in patients with and without VAP were 50.0%(9/18) and 16.7%(151/904), with statistical difference (χ2=11.420, P=0.000). Atomization inhalation was the independent risk factor both of MDROs colonizationin the lower respiratory tract(OR=1.917, 95%CI1.163-3.159, P=0.011) and VAP(OR=4.613, 95%CI 1.773-12.002, P=0.000) in mechanical ventilation patients. Conclusions Atomization inhalation may increase the risk of MDROs colonizationin the lower respiratory tract and VAP in mechanical ventilation patients. Thus unnecessary and too frequent operations of atomization inhalation should be decreased.

ObjectiveTo observe the efficacy and side effects of paroxetine and amitriptyline in the treatment of post-stroke depression (PSD).Methods82 PSD patients were randomly divided into the paroxetine group (n=42) and amitriptyline group (n=40). Before the treatment and at the ends of 2nd, 4th and 8th week after the treatment, all patients in two groups were assessed with Hamilton Depression Scale (HAMD) and TESS.ResultsAfter treatment, HAMD scores of patients of two groups were decreased significantly (P<0.01), but no difference was found between two groups. The side effects of the paroxetine group were obviously fewer and milder than that of amitriptyline group (P<0.01).ConclusionParoxetine is an effective and safe drug in the treatment of PSD.

OBJECTIVETo observe preventive and therapeutic effect of Yifei Jianpi Recipe (YJR) on chronic obstructive pulmonary disease (COPD) model rats and to explore its mechanism from the way of airway inflammation and airway mucus hypersecretion.

METHODSThe COPD rat model was established by using cigarette smoking combined with intratracheal injection of lipopolysaccharide (LPS). Male SD rats were randomly divided into the blank control group (control group), the model group, the YJR group, 6 in each group. Forced vital capacity (FVC), forced expiratory volume in 0. 1 second (FEV0. 1), FEVO. 1/FVC, peak expiratory flow (PEF) was tested by lung function device. Pathological changes of bronchi and lung tissues were observed by HE staining. Airway Goblet cells were observed using AB-PAS staining. Contents of IL-8, IL-17, and TNF-α in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay (ELISA). Protein expressions of intercellular cell adhesion molecule-1 (ICAM-1), nuclear factor KB (NF-KB), mucin 5AC (Muc5AC), and Toll-like receptor 4 (TLR4) in rat airway were detected by immunohistochemical assay. mRNA expressions of TLR4 and Muc5AC in bronchi and lung tissues were detected by real-time quantitative PCR (RT qPCR).

RESULTSChanges of bronchi and lung tissues in the model group rats were consistent with typical pathological manifestations of COPD. Compared with the model group, the degree of lung injury was significantly alleviated in the YJR group. Compared with the control group, FVC, FEV0. 1, FEVO. I/FVC, and PEF were decreased (P <0. 01), contents of IL-8, IL-17, and TNF-α in BALF were significantly increased (P <0. 01), protein expressions of ICAM-1, NF-KB, Muc5AC, and TLR4, mRNA expression levels of Muc5AC and TLR4 in bronchi and lung tissues were also significantly increased in the model group (P <0. 01). Compared with the model group, FVC, FEV0. 1, FEV0. 1/FVC, and PEF were significantly increased in the YJR group (P <0. 01, P <0. 05), but the rest indices were significantly lowered (P <0. 01, P <0. 05).

CONCLUSIONYJR could decrease contents of IL-8, IL-17, and TNF-α in BALF of COPD model rats, inhibit protein expression levels of ICAM-1, NF-κB, Muc5AC, and TLR4.in airway and lung tissues, thus playing preventive and therapeutic roles by reducing airway inflammation and airway mucus hypersecretion.

Objective To investigate the feasibility of new criteria for evaluating the radiotherapeutic effect on esophageal cancer by barium meal (BM) combined with CT scans.Methods A total of 189 patients who were diagnosed with esophageal cancer (confirmed by biopsy) from January 2004 to December 2010 were enrolled as subjects.All patients underwent BM and CT scans before and after radiotherapy.The maximal esophageal wall thickness (EWT) and changes in the volumes of regional lymph nodes measured by CT scans were analyzed.New criteria for evaluating the short-term radiotherapeutic effect on esophageal cancer was studied considering the analysis results as well as the BM-based criteria for evaluating short-term radiotherapeutic effect and follow-up results.Results The BM-based evaluation criteria were still useful,but had certain limitations.There were 115 patients who had regional lymph node metastasis as detected by CT scans before radiotherapy,and they were divided into complete remission (CR) group and partial remission (PR) group according to BM results after radiotherapy; the local control rate (LCR) of CR group was significantly higher than that of PR group,but there was no significant difference in survival rate (SR) between the two groups.There were 65 patients who had no regional lymph node metastasis,and they were also divided into CR group and PR group according to BM results after radiotherapy;the LCR and SR of CR group were significantly higher than those of PR group.In summary,the patients who had a CR as evaluated by BM and had the maximal EWT of ≤ 1.20 cm and the volumes of residual lymph nodes of ≤ 1.00 cm3 on CT were defined as CR ; the patients who had a PR as evaluated by BM or had the maximal EWT of ＞ 1.20 cm or those who had a CR evaluated by BM and had the maximal EWT of ≤ 1.20 cm and the volumes of residual lymph nodes of ＞ 1.00 cm3 on CT were defined as PR.The cases evaluated by BM as no remission (NR) or showing metastasis were defined as NR or progressive disease.There were significant differences in LCR and SR between the CR group and PR group determined by the new criteria.Conclusions Simply using BM to evaluate the short-term radiotherapeutic effect on esophageal cancer has certain limitations; instead,the evaluation based on both BM and CT scans is more accurate.

AIM: To investigate the affected proteins by tumor necrosis factor (TNF)-? in endothelial cells, and further explore the potential molecular mechanism of TNF-? on endothelial cells. METHODS: Nitric oxide (NO) production in the cultured human umbilical vein endothelial cells (HUVECs) was measured by a NO assay kit. Proteomic alterations were analyzed using two-dimensional electrophoresis, and peptide mass fingerprinting with matrix-assisted laser desorption/ionization-time of flight mass spectrometry. RESULTS: NO production in HUVECs decreased significantly after TNF-? treatement. Proteomics analysis showed 21 protein spots were changed including 9 spots that were increased and 11 spots that were decreased after TNF-? stimulation, and 1 spot was only detected in TNF-? activated cell gels. CONCLUSIONS: The decreased expression of ecNOS by TNF-? might result in decrease in NO production. Up-regulated MAP/ERK kinase 3 expression might imply that TNF-? activates the expression of adhesion molecules. Cytoskeletal protein actin is also involved in TNF-? injuried HUVECs. Proteomic analysis can find some clues for identifying new potential target of TNF-?. [
