OBJECTIVETo compare the efficacy differences on delayed encephalopathy after carbon monoxide poisoning (DEACMP) between acupuncture to restore consciousness combined with hyperbaric oxygen treatment and simple hyperbaric oxygen treatment.

METHODSForty-one patients with DEACMP were randomly divided into an observation group (21 cases) and a control group (20 cases). In the observation group, acupuncture was applied at Neiguan (PC 6), Shuigou (GV 26), Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Hegu (LI 4), Sanyinjiao (SP 6) and Taichong (LR 3), and hyperbaric oxygen treatment was given as well. In the control group, simple hyperbaric oxygen treatment was used. The treatment was adopted once every day, and continuous 5 days' treatment made one session in the two groups. There were two days at the interval between two sessions and 6 sessions in the two groups. The changes of scores of mini mental state examination (MMSE) and Barthel index (BI) for activity of daily life and routine electroencephalogram (EEG) before and after treatment were compared.

RESULTSAfter treatment, the scores of MMSE and BI and EEG were all improved compared with those before treatment (all P<0.01). The raise of the scores of MMSE and BI in the observation group was more obvious than that in the control group (both P<0.05) and the improvement of EEG abnormal condition in the observation group was also superior to that in the control group after treatment (P<0.05).

CONCLUSIONAcupuncture to restore consciousness combined with hyperbaric oxygen could obviously improve the cognitive function, activity of daily life and changes of EEG, and it is better than simple hyperbaric oxygen treatment.

Objective To investigate MVD, TSP-1, TGF-?1 expression in GH-Secreting Pituitary Adenomas by immunohistochemistry, and to correlate data with clinical characteristics.Methods The protein expression of TSP-1, TGF-?1 in 48 surgical specimens (21 invasive cases; 27 non-invasive cases) of pituitary adenomas was measured using immunohistochemical method. The relationship between the expression and clinical properties was examined. MVD was measured by detecting CD34.Results Compared with the noninvasive group, no difference of expression of CD34(t=2.257; P=0.083) was observed. The expression of TSP-1 in invasive group was low. The expression of TGF-?1 was higher in invasive cases than that in noninvasive ones. The expression of TGF-?1 had positive correlations with MVD; but there was no correlation between the expression of CD34 and the invasion of pituitary adenomas. In addition, MVD count was not associated with the expression of TSP-1. Size, sex or rate of recurrence did not influence MVD and TSP-1 expression. Conclusion MVD values do not necessarily represent angiogenesis in pituitary adenomas. TGF-?1 may increase MVD, and TSP-1 does not affect MVD in pituitary adenomas and angiogenesis may be regulated by other pathway.

Objective To evaluate the clinical value of serum MUC1(sMUC1)in the patients with multiple myeloma.Methods The enzyme linked immunosorbent assay(ELISA)was used to compare the sMUC1 levels in the 12 cases of newly diagnosed multiple myeloma.15 cases of post-chemotherapy and 46 healthy donors.Results The mean concentration of sMUC1 in the newly diagnosed patients with multiple myeloma was 33.44 U/ml(10.86～88.80 U/ml).In the patients of post-chemotherapy the mean concentration was 11.6U/ml(3.92～22.22 U/ml),and in the healthy donors the concentration was 12.81 U/ml(3.84～30.45 U/ml).The level of sMUC1 in the new diagnosed patients was significandy higher than that in the patients of post-chemotherapy(P=0.001)and healthy donors(P=0.000).There was no significant difference between post-chemotherapy and healthy donors(P=0.461).Conclusion sMUC1 may be one of the tumor markers for the diagnosis of multiple myeloma.sMUC1 could also be used as one of the indicators of prognosis and the evaluation of the chemotherapy efficacy.sMUC1 might be a potential target for the immunotherapy to the patients with multiple myeloma.

BACKGROUND:Idiopathic interstitial pneumonia is of poor response to treatment. Glucocorticoids are the first medicine for the treatment, however there is only 30% of the patients who are responded. Traditional Chinese drugs (TCD) have been researched hot point for prevention and treatment of pulmonary fibrosis. Many TCD have been used clinically, and with a certain therapeutic effect. Transforming growth factor-β1 and tumor necrosis factor-α are the considerable cytokines to cause pulmonary fibrosis, inhibition of their expression, therefore, may be effective to pulmonary fibrosis.OBJECTIVE: To investigate the interventional effect of qidan granule on pulmonary fibrosis in rats induced by bleomycin A5 and the influence on the expressions of transforming growth factor-β1 and tumor necrosis factorα, and also to compare with those of hydrocortisone.DESIGN:A randomized and interval grouping design.SETTING:Department of Respiratory Medicine, Shandong Provincial Hospital, Shandong University.MATERIALS:The experiment was conducted from May 2003 to March 2004 at Pathological Laboratory of Shandong Provincial Academy of Medical Science. Totally 105 SD male rats, were at random divided into 4groups: normal control group (n= 15 ), model group, qidan group and hydrocortisone group, with 30 rats in each group. Each group was subdivided as7-day, 14-day and 28-day group, with 5 rats in each normal group, and 10in each other groups.METHODS: [1] Model establishment: A perfusion was intrabronchially performed, of 0.25 mL normal saline for rats in normal control group, and of bleomycin A5 0.25 mL ( 5 mg/kg,4 g/L) for rats in other 3 groups, to set up the models of pulmonary fibrosis. [2]Administration: Next day to the beginning of modeling qidan granule (consisting of Radix Astragali seu Hedysari, Radix Salviae Miltiorrhizae, Rhizoma Ligustici Chuanxiong and so on, 3 125 mg/kg) was intragastrically given per day for rats in qidan group, hydrocortisone (25 mg/kg) was intraperitoneally given per day for rats in hydrocortisone group, and normal saline (2 mL/rat) was intragastrically given per day for rats in normal and model groups.[3] Observation indexes: The rats in each group were on the day 7, day 14 and day 28 put to death under the anesthesia, then the lung tissue was taken, stained with hematoxyline-eosin stain for pathological observation of lung tissue. The expressions of transforming growth factor-β1 and tumor necrosis factor-α were detected by immunohistochemistry.MAIN OUTCOME MEASURES:Pathological observation of lung tissue,and the expressions of transforming growth factor-β1 and tumor necrosis factor-α at different time points of rats in each group.RESULTS:Totally 100 rats entered the final result analysis.[1]Pathological observation of lung tissue: In the normal group the structure was normal, in the model group there were alveolitis on the day 7, deterioration of alveolitis on the day 14, and extensive fibrosis on the day 28; the degrees of alveolitis and fibrosis in the qidan group were slighter than those in the model group, and there was normal structure of alveoli; and in the hydrocortisone group the alveolitis on the day 7 and 14 was slighter than that in the model group, but there was no significant difference of fibrosis compared with the model group.[2] Expression of transforming growth factor-β1:In the model group the expression was highest on the day 28 and obviously higher than that in the normal group (3.6±0.4,1.2±0.4,P ＜ 0.01 ); the expression in the qidan group and hydrocortisone group was obviously lower than that in the model group(1.7±0.5,2.5±0.4,P ＜ 0.01), and the expression in the qidan group was lower than that in the hydrocortisone group (P＜ 0.01 ). [3]Expression of tumor necrosis factor-α: In the model group at different time points the expression was continuously increased, the expression in the qidan group and hydrocortisone group was obviously lower than that in the model group(P ＜ 0.05 or P ＜ 0.01), and the expression in the qidan group was lower than that in the hydrocortisone group ( P ＜ 0.01).CONCLUSION: Qidan granule can obviously reduce the extent of pulmonary fibrosis in rats induced by bleomycin A5, lower the expressions of transforming growth factor-β1 and tumor necrosis factor-α, and the effect was better than that of hydrocortisone.

The core-crosslinked polymeric micelles were used as a new drug delivery system, which can decrease the premature drug release in blood circulation, improve the stability of the micelles, and effectively transport the drug into the therapy sites. Then the drug bioavailability increased further, while the side effect reduced. Most drugs were physically entrapped or chemically covalent with the polymer in the internals of micelles. Based on the various constitutions and properties of polymeric micelles as well as the special characteristics of body microenvironment, the environment-responsive or active targeting core-crosslinked micelles were designed and prepared. As a result, the drug controlled release behavior was obtained. In the present paper, the research progress of all kinds of core-crosslinked micelles which were published in recent years is introduced. Moreover, the characteristic and application prospect of these micelles in drug delivery system are analyzed and summarized.
