Objective To learn the burnout and turnover intention of physicians from township hospitals in Xi County,Henan province,for reference of health administrators and healthcare institution managers.Methods Cluster sampling method and qualitative interviews were used and all physicians from such hospitals were sampled for questionnaire survey in 2014,with 1 70 scales distributed.The questionnaire was the Markov Burnout Inventory generic version revised by Li Chaoping,and turnover intention questionnaire was that revised by Liang Kaiguang.Results 140 physicians from such hospitals were found with zero or low burnout (94.6%);Collaborative care in the county poses great positive effect on promoting professionalism and interpersonal relations, yet has limited positive impact on reducing workload and performance appraisal stress and increasing their income.Conclusion It is imperative to enhance training of managers of such hospitals for them to learn the appraisal method with organizational scale,and build a humanistic concern mechanism for physicians,for purposes of improving the organizational environment and minimize the burnout and turnover intention of the physicians.

Objective To explore the feasibility and application value of low dose CT with automatic tube current modulation (ATCM) in the diagnosis of pneumoconiosis.Methods Forty-five patients with pneumoconiosis confirmed by the occupational agency underwent standard dose CT scanning with a fixed tube current of 150 mA and low dose CT scanning with ATCM (50-200 mA) with noise index (NI) of 14.The CT dose index volume (CTDIvol) and dose length product (DLP) under the different scanning condition were recorded.The image quality,specific image manifestations of pneumoconiosis (shadow size,shadow concentration,pneumoconiosis stages) were reviewed in double-blind methods by two radiologists,and the statistical analysis was performed.Results CT characteristics of pneumoconiosis could be detected efficiently with low dose CT scanning with ATCM.There were no significant differences in showing the shadow size,shadow concentration,pneumoconiosis stages and the image quality between the two groups (P＞0.05).The CTDIvol and DLP of standard dose CT scanning were 13.53 mGy and (337.13 ± 13.53) mGy/cm respectively,and CTDIvol and DLP of low dose CT scanning with ATCM were (7.39 ± 0.45) mGy and (188.78 ± 1.80) mGy/cm,there were statistical differences (P ＜ 0.05).Conclusions Low dose CT scanning with ATCM can reflect the characteristics of pneumoconiosis,and it also can significantly reduce the radiation dose with diagnostic acceptability of the image quality.So low dose CT scanning with ATCM can replace the standard dose CT scan in diagnosing and screening of the pneumoconiosis.

Objective To analyze the short-term impact of fast track surgery (FTS) combined with minimally inva-sive surgery on elderly patients with colorectal cancer. Methods 200 patients with colorectal cancer received laparo-scopic surgery from July 2013 to July 2015 were selected and randomly divided into control group and FTS group. Patients in control group received conventional perioperative treatment and patients in FTS group received perioper-ative management according to fast track surgery. Status of intraoperative, postoperative recovery and the postopera-tive complication rate were compared between the two groups. Patients' quality of life were analyzed after two weeks of operation. Results Compared with the control group, the blood loss, operation time and number of lymph node dissection of patients in FTS group showed no significant difference ( > 0.05). Flatus time, ambulation time, start eating time, the infusion time and length of hospital stay in FTS group was significantly shorter than the control group, the difference was statistically significant ( <0.05). The total cost of hospitalization of FTS group was signifi-cantly lower than the control group ( <0.05). The incidence of sore throat, abdominal distension, lung infections and overall complications incidence rate in FTS group were significantly lower than the control group, the difference was statistically significant ( <0.05). The satisfaction rate in FTS group was 96.0%(96/100), and was significantly high-er than the control group 82.0 %(82/100), the difference was statistically significant ( < 0.05). QLQ-C30 results showed that scores of overall health, emotional function and social function of FTS group were significantly higher than the control group ( <0.05), and scores of nausea and vomiting, pain, insomnia, anorexia, constipation were sig-nificantly lower than the control group ( < 0.05). Conclusion Laparoscopy combined with FTS is safe and effective in treatment of colorectal cancer in the elderly patients, which can promote postoperative rehabilitation, improve pa-tient satisfaction and quality of life in short term.

3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) is the first rate-limiting enzyme for sesquiterpene synthesis in the mevalonate (MVA) pathway. The specific primers were designed according to the transcript sequence of AsHMGR2 from the Aquilaria sinensis (Lour.) Gilg transcriptome database. The full-length cDNA of AsHMGR2 was cloned by RT-PCR and rapid amplification of cDNA ends (RACE) technology, and was analyzed at bioinformatics levels; AsHMGR2 expression profiles in different tissues and in responds to different treatments were analyzed by real-time PCR. The length of AsHMGR2 Open Reading Frame (ORF) was 1 749 bp, encoding 582 amino acids. The GenBank accession number is KC140287. Tissue expression analysis indicated that AsHMGR2 was mainly expressed in root and shoot tips, followed by stem, and was lowest in leaves. Inducible-experiments showed that the genes were induced by mechanical wound as well as chemical liquid induction, and reached the highest expression level at 6 h and 8 h, separately. The full-length cDNA of AsHMGR2 and its expression patterns will provide a foundation for further research on its function in agarwood sesquiterpene biosynthesis.

The recombinant plasmid pPIC-gpd-bgl-hyg was constructed, which contained GPD2 promotor and terminator from industrial yeasts Saccharomyces cerevisiae, ?-glucosidase gene (BGL1) from Sac-charomycopsis fibuligera and hyg from hygromycin as the selected marker. With the yeast’s high efficiency of homologous integrated, the BGL1 gene was successfully integrated into industrial yeasts S. cerevisiae. The recombined yeast could grow on the cultures with the cellobiose as a sole carbon source, and the ?-glucosidase activity achieved 0.764 U/mL after 48 hours’ cultivation. In the experiments of VHG ethanol fermentation, the cellobiose concentration in broth of recombined yeast was 80% lower than that of indus-trial yeast.
