OBJECTIVE To study the bacteriology of pneumonia and its clinical significance in patients with lung cancer.METHODS The bacteriology and clinical features of patients with lung cancer accompanied with lung infections between 2002 and 2005 in our hospital were analyzed.RESULTS Pneumonia took place in 53.7% of 328 patients with lung cancer,the most of them were elderly people and the chemotherapy receivers,and the rates of pneumonia associated with small cell lung carcinoma(63%) and squamous cell carcinoma(59.7%) were significantly higher than those with adenocarcinoma(44.0%) and alveolar cell carcinoma(40.6%)(P

The recombinant fusion protein staphylokinase-hirudin(rSFH) was purified from the high density-fermented engineered E.coli by means of ion-exchange chromatography (IEC) and gel filtration (GF). The purity of rSFH reached to more than 98% determined by RP-HPLC and SDS-PAGE, and the yield was up to 0.7g per liter of fermentation broth. The analysis of homologous dimmer of rSFH appeared during the purification and calculation of the surface hydrophobic area had been carried out by means of hydrophobic chromatography and MALD-TOF. The influence of sodium chloride and temperature on the behavior of rSFH reversible dimerization was analyzed by high performance sized- exclusive chromatography(HPSEC). It is concluded that the hydrophobic interaction played an important role in the reversible dimerization of rSFH.

Objective To investigate the effects of partial body weight supported treadmill training (BW- STT) on post-stroke depression (PSD) and on patients' quality of life.Methods Sixty patients with PSD were re- cruited and divided into a training group (n=30,male 17,female 13) and a control group (n=30,male 16,fe- male 14).All patients were treated with routine internal medication and rehabilitation.The patients of the training group also received BWSTT in addition to their routine treatment.All patients' neurological impairment was evaluated using the Modified Edinburgh-Scandinavian Stroke Scale (MESSS).The Hamilton depression scale (HAMD) was used for evaluating the degree of depression.The Fugl-Meyer scale and the Barthel index were used to assess ambula- tion and balance,and facility in the activities of daily living.All patients were assessed before and after the treat- ment.Results After four weeks of treatment,depression in the training group had improved significantly more than in the control group.Conclusion BWSTT intervention is very important for patients with PSD:it can reduce the degree of depression and improve the quality of life.

OBJECTIVETo evaluate the safety and efficacy of imatinib in treatment of chronic myeloid leukemia (CML) patients.

METHODSFrom December 2003 to March 2007, 151 patients entered Glivec International Patient Assistance Program (GIPAP) in our center and received imatinib therapy. The overall and progression free survival, hematologic, cytogenetic and molecular response, and adverse events were evaluated. The factors associated with outcome of imatinib therapy were also analysed.

RESULTSOne hundred and forty-two patients were evaluable with a median follow-up duration of 21.5 (6 -78) months. (1) The rate of cumulative complete hematologic response (CHR), major cytogenetic response (MCyR), complete cytogenetic response (CCyR) and complete molecular response (CMoR) in chronic phase (CP) CML patients were 96.9%, 82.6%, 76.1% and 29.4%, respectively. These rates were significantly higher in patients with CP than in those with accelerated phase (AP) and blast crisis (BC) (P < 0.0001). (2) The overall survival (OS) rates at 1, 2 and 3 year were 100%, (97.3 +/- 1.9)% and (95.8 +/- 2.4)% for CP patients, they were (84.7 +/- 8.2)%, (77.0 +/- 10.4)% and (69.3 +/- 11.9)% for AP patients, and (62.9 +/- 8.9)%, (41.9 +/- 9.2)% and (28.5 +/- 9.1)% for BC patients, respectively (P < 0.0001). The progression-free survival (PFS) rates at 1, 2 and 3 year were (98.9 +/- 1.1)%, (93.9 +/- 2.7)%, (93.9 +/- 2.7)% for CP patients, (68.9 +/- 10.6)%, (61.3 +/- 11.9)%, (61.3 +/- 11.9)% for AP patients, (36.4 +/- 8.8)%, (25.4 +/- 8.1)%, (10.1 +/- 8.2)% (P < 0.0001) for BC patients respectively. (3) Among 92 CP patients, the rates of MCyR and CCyR in newly diagnosed patients were significantly higher than those in interferon therapy failure patients (P = 0.015, P = 0.010). Patients obtained CCyR at 12 months after the initiation of imatinib treatment were associated with longer PFS (P = 0.0099). According to the Sokal scoring system, the rates of MCyR and CCyR in low-risk patients were significantly higher than those in intermediate-risk and high-risk patients (P = 0.0013, P = 0.0024). Sokal score was also significantly associated with disease progression (P = 0.0467). (4) The adverse events of imatinib were moderate and tolerable.

CONCLUSIONSTreatment of CML patients in CP with imatinib can induce high hematologic, cytogenetic and molecular response and overall survival, but can not do satisfactorily for patients in AP and BC.

OBJECTIVETo investigate the role of mitogen-activated protein kinases (MAPKs)-extracellular signal regulated kinase1/2 (ERK1/2) signal pathway in the regulation of Compound Danshen Injection (CDI) induced AQP3 expression in the human amniotic epithelial cells (hAECs).

METHODShAECs of term pregnancy with normal amniotic fluid volume (AFV) or isolated oligohydramnios were primarily cultured. And the cells were equally divided into four groups, i.e., the vehicle control group, the U0126 group, the CDI group, the CDI + U0126 group. The expressions of phosphorylated ERK1/2 (p-ERK1/2) and AQP3 in hAECs were detected using Western blot analysis.

RESULTS(1) When compared with the control group, the expression level of p-ERK1/2 in hAECs in those with normal AFV and oligohydramnios obviously decreased in the U0126 group (P < 0.05). The expression level of p-ERK1/2 could be elevated in the CDI group (P < 0.05). The expression level of p-ERK1/2 in hAECs was higher in the CDI +U0126 group than in the U0126 group, but lower in the CDI + U0126 group than in the CDI group (P < 0.05). (2) There was no obvious change in AQP3 expression in hAECs with normal AFV between the U0126 group and the vehicle control group (P > 0.05). There was no statistical difference in the expression level of AQP3 between the CDI group and the U0126 +CDI group (P > 0.05), but they were higher than those in the vehicle control group (P < 0.05). (3) Compared with the vehicle control group, the expression level of AQP3 in hAECs with oligohydramnios significantly decreased in the U0126 group and increased in the CDI group (P < 0.05). The expression level of AQP3 was lower in the U0126 + CDI group than in the CDI group, but higher in the U0126 +CDI group than in the U0126 group (P < 0.05).

CONCLUSIONCDI could regulate AQP3 expression level in hAECs with oligohydramnios via activating the MAPK-ERK1/2 signal transduction pathway.

Objective To investigate the protective effect of modified Qianjin Weijing Decoction(MQJWJD)on TNF-α and NF-κB in rats with lung injury induced by particulate matter; To discuss relevant mechanism of action. Methods A tracheal drip 15 mg/kg fine particles of saline solution was used to establish modeling, every other day, three times. Thirty-two Wistar rats were randomly divided into normal group, model group and MQJWJD high-dose and low-dose groups, with eight rats in each group. Medication groups were given relevant medicine for gavage. The level of TNF-α in bronchoalveolar lavage fluid (BALF) was measured by ELISA. The expression of NF-κB protein in lung tissues was measured by immunohistochemistry. The histopathology of the lung injury was observed by light microscope. Results Compared with normal group, the level of TNF-α and the expression of NF-κB protein in the model group were higher than those in the normal group (P<0.01). Compared with model group, the level of TNF-α and the expression of NF-κB protein in MQJWJD low-dose and high-dose groups were lower than those in the model group (P<0.05, P<0.01). Pathological observation showed that, compared with normal group, model group showed intratracheal, alveolar and interstitial bacteria within a large number of fine particles calm, alveolar and pulmonary interstitial visible large amounts of phagocytic fine particles of macrophages and accompanied by more neutrophils and lymphocyte infiltration; Lung tissue pathological changes were significantly lighter in MQJWJD high-dose and low-dose groups than the model group. MQJWJD high-dose group showed mild inflammation, alveolar and pulmonary interstitial visible phagocytic fine particles of macrophages, a small amount of neutrophils and lymphocyte infiltration. Conclusion MQJWJD can reduce the pulmonary injury in rats induced by particulate matter and has protective effects on the rat model through decreasing the levels of TNF-α and the expressions of NF-κB protein in injured lung tissues.
