BACKGROUNDPulmonary blastoma is a rare primary malignancy of the lung. It is now recognized in two forms: adult type pulmonary blastoma and childhood pleuropulmonary blastoma. The clinical characteristics, diagnosis and treatments of adult type pulmonary blastoma are discussed in this article.

METHODSThe clinical records of 5 patients with adult type pulmonary blastoma admitted in Cancer Center, Sun Yet-sen University from 1964 to 2004 were analyzed and the literature on pulmonary blastoma was reviewed.

RESULTSThree patients were male and two were female with the ages ranged from 22 years old to 70. Their symptoms consisted mainly of cough, hemoptysis and chest pain. The pulmonary blastomas were mainly manifested as a solitary parenchymal mass of the lung on chest radiograph and CT. None of these patients was diognosed by fibrobronchoscopy nor sputum cytology. Three patients underwent lobectomy, one underwent pneumonectomy, and these four patients underwent mediastinal lymph node resection also. The fifth one received wedge resection and postoperative chemotherapy. At the end of follow-up, three patients died and two was alive, and the survival time was from 6 months to 11 years.

CONCLUSIONSPulmonary blastoma is difficult to be diagnosed before operation. Surgery is the best therapeutic choice up to now. It has poor response to radiotherapy and chemotherapy. The prognosis of patient with pulmonary blastoma is variable.

Objective: To explore the status of lymph node metastasis of middle third thoracic esophageal squamous cell carcinoma and its influence on the prognosis and to seek the reasonable range of lymphade-nectomy. Methods: A total of 129 patients who underwent curative esophagectomy with modern two-field lymphadenectomy of middle third thoracic esophageal squamous cell carcinoma were reviewed. Results: The lymph node metastasis rate was 56.6% and the upper mediastinal lymph node metastasis rate was 43.4%. The lymph node metastasis ratio (positive nodes/total dissected nodes, LMR) was 11.3%. Paraesophageal lymph nodes, lymph nodes near the right recurrent nerve, the left gastric and infracadnal lymph nodes were most commonly involved when the tumor was located in the middle thoracic esophagus. Tumor differentiation, the depth of tumor invasion and the length of tumor were influencing factors for lymph node metastasis. The 5-year survival of N_0, N_1 (LMR≤20%) and N_1 (LMR>20%) patients were 50.4%, 31.0% and 6.8%, respective-ly, with a significant difference among the three groups (P=0.000). Conclusion: LMR was one of the key fac-tors affecting the prognosis, of esophageal cancer. Patients with middle third thoracic esophageal carcinoma should be treated with radical surgery with modern two-field lymphadenectomy.

Aim To determine the effective compo-nents of Semen Ziziphi Spinosae for sedative-hypnotic and its mechanism. Methods The extraction of Se-men Ziziphi Spinosae and the rat brain homogenates were prepared. High concentrations of Diazepam com-petitively replaced the ligand compounds of Semen Ziz-iphi Spinosae combining BDZ receptor in brain tissue, and all the compounds with sedative and hypnotic effects were collected and identified by HPLC and LC-MS technique, as the compounds extracted from the brain tissue were administered with Semen Ziziphi Spi-nosae. The brain tissue was administered with Diaze-pam, and with Semen Ziziphi Spinosae and Diazepam. Results The HPLC chromatograms show that the peak time of BDZ receptor ligand compounds was 2. 71 min and 46. 87min, when compared with Diazepam. And the LC-MS chromatograms display the relative molecu-lar weight of the ligand compounds was 274. 28 m/z, 453. 34 m/z,496. 34 m/z and 608. 38 m/z respective-ly. According to the fingerprint of Semen Ziziphi Spi-nosae, these compounds may be fatty acid substances and lupine pill triterpene compounds. Conclusions On the basis of the principle of receptor ligand bind-ing, we established a way to quickly analyze and iden-tify the role of natural products in the same drug target compounds. The method not only can clearly define the effective components of natural products, but also clar-ify the mechanism of action of the compounds. The ac-tive ingredient of calm hypnosis in Semen Ziziphi Spi-nosae may be fatty acid substances Palmitic acid ( C16 H32 O2 ) and lupine pill triterpene compounds Alphitolic acid( C30 H48 O4 ) and Spinosin( C28 H32 O15 ) . They exert their sedative and hypnotic effects by combining with BDZ receptor, and the research has laid a theoretical foundation for the further study about mechanism of Se-men Ziziphi Spinosae.

Objective To explore the effects of application and management of the standardized training system for newly graduated registered nurses. Methods A total of 238 newly graduated nurses in Peking University First Hospital were selected by purposive sampling method. The 138 nurses who were enrolled in August 2015 were assigned into control group, adopting the traditional training program for new nurses. The 100 newly enrolled nurses in August 2016 were assigned into observation group, adopting the new standardized training program for new nurses. After training, the nurses of both groups were evaluated with the Transition Shock of Newly Graduated Nurses Scale (TSNGNS), the New Nurse Standardized Training Satisfaction Questionnaire, and the comprehensive examination paper. Results The total scores of TSNGNS, physical dimension, psychological dimension, social culture and development of nurses in the observation group were lower than those in the control group after training, and the differences were statistically significant (P＜0.01). After training, the total score and each dimension score of nurse satisfaction questionnaire in the observation group were higher than those in the control group, and the differences were statistically significant (P＜0.05). After the training, the comprehensive examination score of the nurses in the observation group was higher than that in the control group, and the difference was statistically significant (P＜ 0.01). Conclusions The implementation of the new training scheme can effectively relieve the new nurses' transition shock and improve their satisfaction and comprehensive evaluation score during training.

Background::High-dose dual therapy (HDDT) with proton pump inhibitors (PPIs) and amoxicillin has attracted widespread attention due to its favorable efficacy in eradicating Helicobacter pylori ( H. pylori). This study aimed to compare the efficacy and safety of high-dose PPI–amoxicillin dual therapy and bismuth-containing quadruple therapy for H. pylori rescue treatment. Methods::This was a prospective, randomized, multicenter, non-inferiority trial. Patients recruited from eight centers who had failed previous treatment were randomly (1:1) allocated to two eradication groups: HDDT (esomeprazole 40 mg and amoxicillin 1000 mg three times daily; the HDDT group) and bismuth-containing quadruple therapy (esomeprazole 40 mg, bismuth potassium citrate 220 mg, and furazolidone 100 mg twice daily, combined with tetracycline 500 mg three times daily; the tetracycline, furazolidone, esomeprazole, and bismuth [TFEB] group) for 14 days. The primary endpoint was the H. pylori eradication rate. The secondary endpoints were adverse effects, symptom improvement rates, and patient compliance. Results::A total of 658 patients who met the criteria were enrolled in this study. The HDDT group achieved eradication rates of 75.4% (248/329), 81.0% (248/306), and 81.3% (248/305) asdetermined by the intention-to-treat (ITT), modified intention-to-treat (MITT), and per-protocol (PP) analyses, respectively. The eradication rates were similar to those in the TFEB group: 78.1% (257/329), 84.2% (257/305), and 85.1% (257/302). The lower 95% confidence interval boundary (–9.19% in the ITT analysis, –9.21% in the MITT analysis, and –9.73% in the PP analysis) was greater than the predefined non-inferiority margin of –10%, establishing a non-inferiority of the HDDT group vs. the TFEB group. The incidence of adverse events in the HDDT group was significantly lower than that in the TFEB group (11.1% vs. 26.8%, P < 0.001). Symptom improvement rates and patients’ compliance were similar between the two groups. Conclusions::Fourteen-day HDDT is non-inferior to bismuth-containing quadruple therapy, with fewer adverse effects and good treatment compliance, suggesting HDDT as an alternative for H. pylori rescue treatment in the local region. Trial registration::Clinicaltrials.gov, NCT04678492.
