Objective:To explore the status and influencing factors of nurses′ cognitive ability of nursing interruptions in operating room.Methods:From March to May 2020, convenient sampling was conducted, a questionnaire was used to investigate the cognitive ability of operating room registered nurses in some provinces and cities in China. The influencing factors were analyzed by single factor analysis and multiple stepwise linear regression analysis.Results:Finally, 2 827 questionnaires were collected from 1 municipality directly under the central government and 15 provinces, involving 42 municipal and county hospitals. The nurses′ cognitive ability of nursing interruptions in operating room scored 105.73 ± 13.39, which was in the middle level. A total of 2 427 (87.37%) operating room nurses thought it necessary to receive training on nursing interruptions, but only 796 (28.16%) nurses had received training on nursing interruptions. Multiple stepwise linear regression analysis showed that different job categories ( B=-0.714, P<0.001), whether to pay attention to nursing interruptions ( B=5.449, P<0.001), the frequency of experience nursing interruptions ( B=-1.916, P<0.001)and whether to participate in the training of nursing interruptions ( B=-4.806, P<0.001) were the influencing factors of operating room nurses' cognitive ability of nursing interruptions. Conclusions:The operating room nurses' cognitive ability of nursing interruptions is in the middle level. The current situation of training is not good, but the training demand is high. Managers should strengthen the systematic training of nurses on nursing interruptions, especially those with junior nurses in operating room, to improve nurses' attention and cognitive ability of nursing interruptions.

Multi-disciplinary team(MDT)mode is regarded as the key to standardized diagnosis and treatment of malignant tumors. The model, however, encounters such roadblocks in the current form of MDT organization, as costly clinical resources and time consumption, low efficiency, poor management of participating experts in MDT, and lack of enforceability of the therapeutic decisions made. This paper summarized the practical MDT experiences of the Affiliated Cancer Hospital of Shandong First Medical University. It introduced the construction of an intranet-based MDT system covering a large proportion of newly diagnosed malignant tumor patients, and the practices and achievements of such MDT management system under hospital administrative guidance. The authors proposed to use reporting ratio as the main assessment indicator in promoting MDT, and that to define the performance, responsibilities and rights in MDT practice. These measures aim at to upgrading individual behaviors of doctors to organizational behaviors of hospitals, and providing cancer patients with more standardized, comprehensive and personalized diagnosis and treatment decisions.

Objective:To explore the correlation between fluoride intake and serum alkaline phosphatase (ALP) in pregnant women of different gestational periods in endemic fluorosis area.Methods:Pregnant women in Rencheng District, Jinxiang County, Jiaxiang County of Jining City and Yuncheng County of Heze City were selected in April 2020. According to the gestational weeks, pregnant women were divided into early pregnancy group (0 - 12 weeks), middle pregnancy group (13 - 27 weeks) and late pregnancy group (> 27 weeks). The levels of urinary fluoride, ALP, osteocalcin (BGP), C-terminal peptide of β-Ⅰ collagen (β-CTX) and N-terminal propeptide of type Ⅰ collagen (PINP) of pregnant women in each group were measured, and the correlation between urinary fluoride and ALP, BGP, β-CTX, and PINP in pregnant women of different gestational periods was analyzed.Results:A total of 372 pregnant women were selected, including 97 cases in early pregnancy group, 169 cases in middle pregnancy group and 106 cases in late pregnancy group. There was no significant difference in urinary fluoride level between the three groups [(1.20 ± 0.25), (1.23 ± 0.19), (1.24 ± 0.30) mg/L, P > 0.05]. There was significant difference in serum ALP among the three groups ( P < 0.05), among them, the ALP level in early pregnancy was significantly lower than those of middle pregnancy group and late pregnancy group ( P < 0.05), and the ALP level in middle pregnancy was significantly lower than that of late pregnancy group ( P < 0.05). There was no significant differences in serum β-CTX among the three groups ( P > 0.05). There were significant differences in serum BGP and PINP levels among the three groups ( P < 0.05). The serum BGP and PINP levels in late pregnancy group were significantly higher than those of early pregnancy group and middle pregnancy group ( P < 0.05), and there were no significant differences in serum BGP and PINP levels between early pregnancy group and middle pregnancy group ( P < 0.05). There was a significant positive correlation between urinary fluoride and ALP in early pregnancy group ( r = 0.364, P < 0.05), but no significant correlation between urinary fluoride and BGP, β-CTX and PINP ( r = 0.164, 0.117, 0.136, P > 0.05). There was a significant positive correlation between urinary fluoride level and ALP in middle pregnancy group ( r = 0.417, P < 0.05), but no significant correlation between urinary fluoride level and BGP, β-CTX and PINP ( r = 0.127, 0.108, 0.129, P > 0.05). There was no significant correlation between urinary fluoride level and ALP, BGP, β-CTX and PINP in late pregnancy group ( r = 0.179, 0.158, 0.184, 0.149, P > 0.05). Conclusions:The urinary fluoride level of pregnant women in endemic fluorosis area is relatively stable in gestational period. The urinary fluoride level affects the ALP secretion of pregnant women in early and middle pregnancy. It is still necessary to strengthen the measures of improving water quality and defluoridation to reduce the impact of excessive fluoride intake on pregnancy complications in endemic fluorosis area.

摘要
The lignocellulolytic filamentous fungus Neurospora crassa is able to assimilate various mono- and oligo-saccharides. However, more than half of predicted sugar transporters in the genome are still waiting for functional elucidation. In this study, system analysis of substrate spectra of predicted sugar transporters in N. crassa was performed at genome-wide level. NCU01868 and NCU08152 have the capability of uptaking various hexose, which are named as NcHXT-1 and NcHXT-2 respectively. Their transport activities for glucose were further confirmed by fluorescence resonance energy transfer analysis. Over-expression of either NcHXT-1 or NcHXT-2 in the null-hexose-transporter yeast EBY.VW4000 restored the growth and ethanol fermentation under submerged fermentation with glucose, galactose, or mannose as the sole carbon source. NcHXT-1/-2 homologues were found in a variety of cellulolytic fungi. Functional identification of two filamentous fungal-conserved hexose transporters NcHXT-1/-2 via genome scanning would represent novel targets for ongoing efforts in engineering cellulolytic fungi and hexose fermentation in yeast.

<p><b>OBJECTIVE</b>The distal external iliac lymph nodes are located along the external iliac artery between the deep circumflex iliac vein and the inguinal canal. Our study aimed to investigate the incidence of metastasis in distal external iliac lymph nodes and its association with clinicopathological factors in patients with early stage cervical cancer, and to determine the role of distal external iliac lymph nodes dissection in the surgery.</p><p><b>METHODS</b>Five hundred and twenty-four patients with early stage cervical cancer underwent radical hysterectomy and bilateral pelvic lymphadenectomy in the Shandong Province Cancer Hospital between June 1995 and December 2011, and their clinicopathological features were analyzed retrospectively.</p><p><b>RESULTS</b>Of the 524 patients, 124 (23.7%) had pelvic lymph node metastasis. The metastasis rates were 16.2% (85 of 524 patients) in the obturator lymph nodes, 12.2% (64 of 524 patients) in the internal and external iliac lymph nodes, 2.9% (15 of 524 patients) in the common iliac lymph nodes, 2.1% (11 of 524 patients) in the distal external iliac lymph nodes, and 1.7% (9 of 524 patients) in the para-aortic nodes. The incidence of isolated positive distal external iliac lymph nodes was 0.2%. Univariate analysis showed that lymphovascular space invasion, pelvic lymph node metastases (excluding distal external iliac lymph nodes) were significantly associated with distal external iliac lymph node metastasis (P < 0.05). Logistic regression analysis showed that pelvic lymph node metastasis (excluding distal external iliac lymph nodes) was the independent risk factor for metastasis to distal external iliac lymph nodes.</p><p><b>CONCLUSIONS</b>In early stage cervical cancer, distal external iliac lymph node metastasis is rare, especially in cases with stage IA or without pelvic lymph node metastasis. Less extensive pelvic lymphadenectomy may be considered in these patients in order to reduce operative complications and improve patients' quality of life. The deep circumflex iliac vein may be an appropriate landmark for the caudal limit of external iliac lymphadenectomy. However, if pelvic lymph node metastasis (excluding distal external iliac lymph nodes) is found by intraoperative rapid pathological diagnosis, systematic pelvic lymphadenectomy including removal of the distal external iliac lymph nodes should be performed in order to reduce the risk of distant metastasis.</p>

Objective: This study aims to observe the efficacy and toxicity of three-dimensional conformal radiotherapy (3DCRT) combined with weekly topotecan hydrochloride (Top-Hyd) chemotherapy on patients with platinum-resistant recurrent ovarian cancer. Methods: Medical data of 42 patients with platinum-resistant recurrent ovarian cancer between June 2008 and June 2011 were retrospectively reviewed. OAOf these 42 patients, 22 underwent 3DCRT combined with weekly Top–Hyd chemotherapy, whereas the remaining 20 underwent simple chemotherapy (SCT). Doses from 45 Gy to 65 Gy were planned to deliver fractions ranging from 1.8 Gy to 2 Gy to patient abdomen and pelvis. Top–Hyd (4 mg/m2) was aintravenously administered 1, 8, and 15 days from radiotherapy, with a cycle of 28 days. Results: By December 31, 2011, the median follow-up time for the 3DRT group was 18.5 months, whereas that for the SCT group was 10.8 months . The total response rate and the clinical beneficial rate were significantly higher in the 3DCRT group than in the SCT group (total response rate, 42.1% vs. 11.1%; clinical beneficial rate, 68.4% vs 22.2% at P0.05). Conclusion: The combined 3DCRT treatment and Top-Hyd chemotherapy results in enhanced response and tolerable toxicity compared with SCT in patients with recurrent ovarian cancer infiltrating the pelvic and retroperitoneal lymph node metastasis. So, it may be the salvage regimen for recurrent ovarian cancer and provide a new therapeutic option for the consolidation treatment of advanced ovarian carcinoma.
