Objective To summarize the perioperative nursing of patients with post-thoracotomy atelectasis treated with bronchoalveolar lavage combined with pulmonary insufflation.Methods Before operation,the nursing measures included the full preoperative preparation,full anesthesia and mental care.During the operation,the nursing focused on intensified monitoring,close cooperation with doctors in manipulation of bronchoalveolar lavage and pulmonary insufflation.After operation,the postoperative nursing was performed.Results The lung recruitments were successful in all the 12 patients.Compared to pre-operation,the arterial oxygen saturation(SaO2)and arterial oxygen partial pressure(PaO2)6 hours after treatment were significantly improved(P<0.05) while the CO2 partial pressure(PaCO2)was significantly decreased(P<0.05).There were no severe complications and no recurrence of pulmonary atelectasis.All the patients were successfully discharged.Conclusions The bronchoalveolar lavage combined with pulmonary insufflation is effective in treating post-thoracotomy atelectasis.To ensure the smooth treatment,perioperative nursing is also contributive.

A myxobacterial strain, So ce cpu-1, was isolated from a soil sample near the Huanghai beach. So ce cpu-1 had broad antimicrobial activity, active component has maxima] absorption at 210 nm. The effects of different culture conditions on the yield of the secondary metabolites were investigated. The results showed that, when cultivating the strain in the M, medium (containing 10% w/v D312 neutral absorber resin ), the air up to 70% of the whole flask volume, adding 5?L the secondary metabolites as the revulsant, at 30℃, 200r/min, for 6 days, the yield of the secondary metabolites achieved the maximum.

Objectives: To evaluate the safety and efficacy of CT-guided iodine 125 seed implantation combined with gemcitabine and 5-fluorouracil (5-FU)-based intra-arterial perfusion in the treatment of patients with advanced pancreatic cancer. Methods: A total of 16 patients with advanced unresectable pancreatic cancer underwent CT-guided iodine implantation combined with gemcitabine plus 5-FU-based intra-arterial perfusion. One week after implantation of iodine 125 seeds, all the patients received concurrent intra-arterial infusion of gemcitabine and 5-FU, which was repeated for 3 to 4 cycles. Three patients complicated with liver metastasis were given additional arterial embolization concurrently. Survival period, pain-relieving period, and adverse reaction of patients were observed. Results: All the patients were followed up for 2-25 months. CT scan found that there were 2 cases with complete response, 9 cases with partial response, 3 cases with stable disease, and 2 cases with progressive disease after 2 months of follow-up. The overall effective rate (CR + PR) was 68.8%. The median survival period for all enrolled patients was 11 months. It was 15 months for patients at stage II + III and 9 months for those at stage IV. No serious complications including gastrointestinal bleeding, pancreatitis, pancreatic fistula and radiation colitis were observed. Conclusion: CT-guided iodine 125 seed implantation combined with gemcitabine and 5-fluorouracil (5-FU)-based intra-arterial perfusion has better palliative pain-relieving effects. It has safe and effective effects in short terms and causes less complications in the treatment of advanced pancreatic cancer patients.

Objective: To investigate the expressions of P-glycoprotein (P-gp), topoisomerase II alpha (ToPo II α), glutathione-S-transferase-pi (GST-π), and oncogene c-erbB2 in endometrial cancer and their significance. Methods: Immunohistochemistry SP method was used to determine the expressions of P-gp, ToPo II α, GST-π and c-erbB2 in 127 tumor samples from patients with endometrial cancer. Results: Among 127 tumor samples from patients with endometrial cancer, the positive expression rates of P-gp, ToPo II α, GST-π and c-erbB2 were 63.0%, 44.9%, 70.1%, and 47.2%, respectively. The co-expression rate of P-gp and GST-π was 50.7%. The expression levels of P-gp, GST-π and c-erbB2 in poor differentiation endometrial cancer were significantly higher than those in well/moderate differentiation endometrial cancer (P < 0.05). While the expression level of ToPo II α in well/moderate differentiation endometrial cancer was significantly higher than that in poor differentiation endometrial cancer (P < 0.05). Univariate analysis indicated that the expression of P-gp, GST-π and c-erbB2 were associated with the survival time and poor prognosis of endometrial cancer patients. COX regression analysis suggested that the expression of P-gp and co-expression of P-gp and GST-π correlated with the survival rate of patients. Over-expression of ToPo II α tended to have protective effects on patients. Conclusion: Multidrug resistance-associated protein (MRP), GST-π, Topo II α, and lung resistance protein (LRP) plays important roles in the multidrug resistance(MDR) of tumor chemotherapy. Combined effects of the four multiple factors, P-gp, ToPo II α, GST-π and c-erbB2 were the main action mechanism for the MDR of endometrial cancer. It has an important guiding significance for predicting the prognosis and making rational chemotherapeutic regimens for patients with endometrial cancer.

Objective To observe the changes of specific proteins in serum of acute stage patients with SARS and its clinical application. Methods The acute stage patients with SARS group included 42 cases who had clinical symptoms less than five days. In normal group: 30 healthy adults were as controls. Tests for specific proteins were immunoglobin G ( IgG ) , immunoglobin A ( IgA) , immunoglobin M ( IgM) , complement C3( C3),complement C4(C4),C-reaction protein (CRP), al acid glycoprotein( a1-AG) , a1 antitrypsin(a1-AT) ,transferrin(TRF), ceruloplasmin( CER) in sera by Ratenephelometer. Results The level of CRP, a1-AG, a1-AT in sera of patients with SARS were higher than that in control group ( P 0. 05). Conclusion It suggested that specific proteins in serum of acute stage patients with SARS change in a particular way. There were some help for the diagnosis of the phlogistic degree of acute stage patients with SARS by detecting CRP, a1-AG and TRF simultaneously.
