Objective To observe the effects of respiratory training on pulmonary function in the patients with chronic obstructive pulmonary disease(COPD). Methods A total of 74 patients with COPD were recruited and randomly divided into a treatment group and a control group with 37 subjects in each.The treatment group re-ceived respiratory training including lip-contracting breathing,abdominal breathing and breathing exercises for 6 months in addition to routine medical treatment.The control group received only routine medical treatment.Pulmona-ry function was evaluated before and after treatment. Results After treatment,both groups improved in terms of all the pulmonary function measures,showing increased vital capacity(VC),forced expiratory volume after 1 s(FEVl),peak forced expiratory flow rate(PEFR),as well as forced expiratory flow at 25%of Vcmax(V25),de-creased residual volume and residual volume as a percentage of total lung capacity(RV/TCL).The difference be-tween the two groups was significant with regard to the extent of improvement. Conclusion Respiratory training can improve the pulmonary function of COPD patients.

Objective Human serum albumin ( HSA) is a kind of plasma protein , which can transport various small molecu-lar substances to the body.A disulfide bond breaking strategy is used to fabricate HSA-curcumin nanoparticles(NPs-CCM) in order to improve the solubility and tumor targeting capability of curcumin . Methods NPs-CCM were fabricated with dithiothreitol as the re-ducing agent .The size and shape of the nanoparticles were observed with high resolution electron microscopy .We explored the change of hydrophobic region during the process of degeneration of albumin , the releasing behavior in the solution and the tumor targeting capa-bility in vivo and vitro of NPs-CCM. Results The diameter of NPs-CCM was about 150 nm.The determination of surface hydropho-bicity showed that ANS fluorescence intensity decreased gradually as the extension of degeneration time , at the time 0 min, 2 min, 5 min and 10 min, ANS relative fluorescence intensity was 5492(5432-5673), 2486(2319-2878), 1998(1904-2317), 1503 (1280-1584) respectively.The hydrophobic region of albumin gradually reduced during the degeneration time .The curcumin re-leased from NPs-CCM amounted to about 50% within 40 h, and the NPs-CCM can be absorbed by tumor cells and accumulation in tumor tissue. Conclusion Albumin can improve the solubility and tumor targeting capability of curcumin , and it has potential clinical application value.

Objective To study the impact of enteral nutrition (EN) or parenteral nutrition (PN) in postoperative colorectal cancer patients on viscera organ function and "passing wind" time.Methods Totally 30 patients with colorectal cancer joined this study with informed consent.Patients were randomly divided into EN group and PN group.Both two groups were given nutritional support from the first post-operative day to the 7th post-operative day.The pre-operative and post-operative viscera organ functions and the recovery time of gastrointestinal functions are observed.Results Total bilirubin was significantly lower in EN group than in PN group (P ＜ 0.05).The length of post-operative hospital stay was significantly shorter in EN group than in PN group (P ＜0.01).The post-operative complications were not significantly different between two groups (P ＞ 0.05).Conclusion Postoperative EN support is beneficial for colorectal cancer patient in terms of lower bilirubin levels,shorter post-operative hospital stay,and lower cost.

ObjectiveTo investigate the mechanism of anti-inflammatory effect of diallyl sulfide (DAS) in protection against acute lung injury (ALI) in rats with paraquat poisoning.Methods Eighty male Wistar rats were randomly divided into four groups, namely: control group, model group, dexamethasone (DXM) treatment group, and DAS treatment group, with 20 rats in each group. The model of paraquat poisoning was reproduced by single does of 70 mg/kg given by gavage, while the same volume of normal saline (NS) was given in same manner in control group. 100 mg/kg of DAS, the same volume of NS, or 1 mg/kg DXM injection were given respectively in DAS treatment group, model group, or DXM treatment group intraperitoneally after exposure to paraquat, once a day for 14 days. Five rats in each group were sacrificed at 1, 3, 7, 14 days, respectively. The inferior lobe of right lung was harvested, and the degree of lung injury was observed with hematoxylin and eosin (HE) staining under optical microscope; the upper lobe of right lung was used to determine the lung wet/dry weight (W/D) ratio and for evaluation of the degree of pulmonary edema. The expression of nuclear factor -κB (NF-κB) in the middle lobe of right lung was assessed with immunohistochemistry. The expression of tumor necrosis factor -α (TNF-α) mRNA in the left lung was determined with the reverse transcription-polymerase chain reaction (RT-PCR).Results① The pulmonary structure in control group was found to be intact. However, in the model group there were progressive pathological changes in lung, including marked edema and thickening of alveolar walls, collapse of alveoli, infiltration of inflammatory cells, alveolar wall, and obvious bleeding in the local lung tissue, and formation of transparent membrane in alveolar space. Less infiltration of inflammatory cells and no obvious destruction were found in alveolar structure in the DAS and DXM treatment groups.② Lung W/D ratio: lung W/D ratio of model group was apparently higher than that in control group at every time point, and peaking on the 3rd day (6.15±0.54 vs. 4.15±2.10,P< 0.05), and the ratio of lung W/D of DAS and DXM treatment groups was obviously lower than that in model group at every time point, especially on the 3rd day (3.99±1.26, 4.30±0.70 vs. 6.15±0.54, bothP< 0.05), but there was no significant difference between DAS and DXM treatment groups in this regard.③ The immunocytochemistry analysis revealed minimal NF-κBp65 expression in the cell nuclei of the control group, while extensive NF-κBp65 expression was found in model group. Minimal NF-κBp65 positive expression in the cytoplasm and even less positive expression in the nucleus was found in the DAS and DXM treatment groups, and integralA value was significantly lower in the DAS and DXM treatment groups than that of the model group, especially on the 3rd day [(17.98±0.06)×107, (18.53±0.04)×107 vs. (28.85±0.61)×107, bothP< 0.01], but there was no significant difference between DAS and DXM treatment groups.④ It was shown by RT-PCR that the expression of TNF-α mRNA in lung tissue of the model group was significantly higher than that in the control group on the 3rd day (gray value: 3.63±0.62 vs. 0.51±0.13, P< 0.05). The expression of TNF-α mRNA in lung tissue was significantly decreased in DAS and DXM treatment groups compared with model group (gray value: 2.49±0.57, 2.02±0.26 vs. 3.63±0.62, bothP< 0.05), but there was no significant difference between DAS and DXM treated groups.ConclusionTreatment with an intraperitoneally injection of DAS is capable of attenuate the extent of PQ-induced ALI in rats by alleviating pulmonary edema, inhibiting the expression of NF-κB and TNF-α in lung tissue, and ameliorating pathological changes in lung tissue.
