Objective To describe the results of the Universal Newborn Hearing Screening (UNHS) in Beijing in 2010; and investigatethe factors related with the results. Methods The result of the UNHS investigated by 106 maternity hospitals were reported. These hospitalswere investigated with the self-made questionnaire. Results In 2010, 159888 infants (91.99%) were screened in 106 maternity hospitals inBeijing as the 1st stage UNHS. 10.32% of them failed OAE tests. 72.30% received the 2nd stage UNHS and 13.27% of them failed testsagain. The referral rate was 0.99% in the end. The screening rate of both the 1st and 2nd stage was more in the newborn with Beijing householdregistration than in those with other household registration, as well as the hospitals in urban than in rural areas. For the rate fail in the1st stage UNHS, it was more in hospitals in urban than in rural areas, with distortion product otoacoustic emission (DPOAE) than with transientevoked otoacoustic emissions (TEOAE), by the bed than in the special room, and screening only once than screening again. ConclusionThe quality of UNHS is as high as in the developed countries in the newborn with Beijing household registration. To further improvethe screening rate, it is important to focus on the newborn with other household registers and the hospitals in rural areas. The instrument, personnelqualifications, environment and operation need to be further standardized.

Objective To study the universal newborn hearing screening (UNHS) results obtained in Beijing from 2007 to 2010 and to evaluate the index of hearing screening in Beijing. Methods The newborn born in Beijing just from October 1, 2007 to September 30, 2010 were selected and their hearing screening and diagnosis data were retrospectively collected. Results From 2007 to 2010, 470537 infants (90.2%) were screened in Beijing as 1st stage UNHS. 43019(9.1%) failed otoacoustic emission (OAE) tests. 31009 infants (72.8%) were screened in 2nd stage UNHS and 4568 failed tests. 1262 infants were referred for more testing and 1087 of them were diagnosed regularly.501infants were normal. 266 infants were finally diagnosed with single hearing loss and 303 infants were diagnosed with binaural hearing loss. 61infants were diagnosed with severe binaural hearing loss. Conclusion Establishment of the perfect newborn hearing screening system and advanced information system, and follow-up for the suspected children actively by doctors of community health care unit facilitate to improve UNHS.

Objective To evaluate the effect of case-based learning combined with standardized patients in probation of nuclear radionuclide therapy.Methods 360 interns were randomly assigned separately into CBL+SP group and LBL group (180 people),case based on SP as the center of clinical teaching mode was used for CBL+SP group,while traditional classroom teaching mode was used for LBL group.Theoretical test,case analysis and teaching satisfaction survey were used to evaluate the two teaching mode,using SPSS 20.0 software for statistical analysis of the data.t test was used for two independent samples of both theoretical test and case analysis and chi-square test was used for teaching satisfaction survey.Results The score of theory and case analysis of CBL+SP group was higher than that of LBL group,and the difference had statistical significance [(83.26 ± 4.18) vs.(80.36 ± 3.62),t=-7.041,P=0.000;(85.79 ± 4.15) vs.(81.26 ± 3.96),t=-10.844,P=0.000].Satisfaction survey showed that satisfaction degree of CBL+SP group in stimulating and training the correct clinical thinking,grasping the information skills and cultivating their ability to analyze and solve the problem was higher than that of LBL group,and the difference had statistical significance (x2=40.319,x2=33.620,x2=23.493,x2=23.283;P=0.000).Conclusion Case-based learning combined with standardized patients in probation of nuclear radionuclide therapy can obtain satisfactory teaching effort.

Objective To investigate the mouse liver blood vessel images using phase contrast X-ray imaging with synchrotron radiation. Methods 6 female C57BL/6 mice were randomly divided into two groups, 3 mice in each group. In one group, livers excised after hgated arteries, veins and common bile duct. In another group, iodine infused via the portal vein and drained from inferior vena cave until all the blood in the portal veins and hepatic veins was displaced. After infusion, arteries, veins and common bile duct were ligated and livers were excised. Results Blood vessel images were clearly produced by diffraction enhanced imaging. This method can discriminate vessels down to about 40 μm in diameter without contrast agent. Using a contrasting agent more details could be produced. In one liver lobe, the entire branch of the portal vein could be clearly produced by one by one phase contrast image from the main axial blood vessels of liver lobe to the nine generation of branching. Conclusions Phase contrast imaging has the advantage of good contrast and high spatial resolution.

This paper explores the logic of scientific research management system of public hospitals in the new era,i-dentifying its connotations,principles,and pathways.From a value perspective,the system underscores the integration of effi-ciency and equity.In terms of governance logic,it advocates a shift from a single government-centric approach to a collaborative model that includes both government and market operation logics.The principles guiding transformation advocate for combination of ethical and market considerations,balance of rights and responsibilities,and integration of individual self-efficacy and organi-zational support.In terms of pathway selection,the paper proposes a comprehensive strategy that begins with forging a unified sci-entific research vision,serving as the foundation for creating a pedagogical organization to foster continuous learning,and the im-plementation of performance assessments based on core value.These strategies aim to modernize and enhance the efficiency of the scientific research management system in public hospitals.

Objective To investigate the establishment,operation and performance of external quality assessment(EQA) system for microbial morphology and detection of special drug-resistance in clinical laboratory,and explore the value of the developed system in clinical application.Methods The pictures of known bacteria and fungi colony,gram staining and acid-fast staining from clinical microbiology were distributed to the participating laboratories in Gansu province twice a year at regular intervals.The pictures of standard knowledge points from CLSI,such as special drug resistance were distributed simultaneously.All the participating laboratories were required to complete the interpretation for the pictures and report their resuhs in a scheduled time.Then the resuhs were summarized and analyzed as 3 modes:complete consistency,general consistency and non-consistency.Results During the 2 years when the EQA system for microbial morphology and detection of special drug-resistance were performed for 24 times,the rate of annual complete consistency increased year by year and reached to 91.3％ in 2015.Conclusion The EQA system based on the examinations of microbial morphology and CLSI standard knowledge points for clinical laboratory may supervise the staff of clinical microbiology laboratories in the hospitals at second grade or above to master the skills of morphological identification and learn CLSI knowledge points,so their professional skills of clinical microbiology could be comprehensively improved.

Objective To explore the effects of nursing intervention based on health belief model (HBM) in improving compliance of screen by gastroscope in high risk group of gastric cancer so as to provide theoretical bases for clinical nursing activity.Methods High risk group of gastric cancer with preliminary screening without completing gastroscopy from five communities of Yanta District, Beilin District, Lianhu District of Xi'an City were selected by convenience sampling from 20th March 2015 to 15th December 2016. They were divided into observation group (n=500, conventional education on screening of gastric cancer) and control group (n=500, nursing intervention based on HBM for one year) with the method of random number table. And then, the cognition, score of health belief and the screening rate of gastroscope of both groups were compared. Results After intervention, the scores of all dimensions on cognition about gastric cancer in observation group were higher than those in control group with significant differences (P<0.05). There were statistically significant differences in scores of all dimensions on cognition about gastric cancer before and after intervention in observation group (P<0.05), while there was no statistically significant differences in those in control group (P>0.05). There were also statistically significant differences in scores of all dimensions of health belief between two groups (P<0.05). Compared within groups, there was no statistically significant differences in scores of all dimensions of health belief except for self efficacy in control group before and after intervention (P>0.05), while there were statistical significances in scores of all dimensions in observation group (P<0.05). After intervention, the screening rate of gastroscope in observation group was significantly higher than that in control group (P<0.05).Conclusions The nursing intervention based on HBM helps high risk group of gastric cancer sets up health belief, improves the participation rate of screening by gastroscope along with having important significance for the discovery rate of early gastric cancer.

Objective To investigate the effectiveness and feasibility of standardized nursing training in reducing the incidence rate of post-endoscopic retrograde cholangiopanography(ERCP) pancreatitis. Methods A total of 521 patients were collected from January 2015 to June 2016 in ERCP therapy as control group.The patients in this group did not have standardized nursing training.A total of 289 patients were selected from July 2016 to April 2017 in ERCP therapy as intervention group.The patients in this group were carried out the standardized nursing training. The incidence of hyperamylasemia and post-ERCP pancreatitis was observed in two groups. Results The incidence of hyperamylasemia and post-ERCP pancreatitis was 12.09%(63/521),7.87%(41/521)in control group,and 7.61% (22/289), 3.11% (9/289) in intervention group,the difference was statistically significant between two groups(χ2=3.972,7.258,P<0.05 or 0.01). Conclusions The standard nursing training and intraoperative coordination can reduce its risk factors, and to reduce the post-ERCP pancreatitis and hyperamylasemia has important meaning and function.

OBJECTIVE To observe the clinical efficacy of Yangyin Jiedu Decoction in the prevention and treatment of acute ra-diation-induced oral mucositis(RTOM).METHODS A total of 80 inpatients who were diagnosed with head and neck tumors by pathological examination and received radiotherapy in the Department of Radiotherapy,Affiliated Hospital of Nanjing University of Chi-nese Medicine from November 2021 to September 2023 were selected and randomly divided into an observation group and a control group with 40 cases in each group.The control group was given mouthwash treatment from the onset of RTOM symptoms until the symp-toms disappeared;the observation group was given Yangyin Jiedu Decoction from the first day of radiotherapy on the basis of the treat-ment of the control group until the end of radiotherapy.During the treatment,the onset time,duration and incidence of grade Ⅱ-ⅣRTOM in the two groups were observed;the pain numerical rating scale(NRS)score,Karnofsky performance status(KPS)score,body mass index(BMI)changes were evaluated;and the levels of serum inflammatory factors[C-reactive protein(CRP),interleukin 6(IL-6),interleukin 1β(IL-1β),tumor necrosis factor α(TNF-α)]were detected.RESULTS After radiotherapy,RTOM ap-peared in both groups to varying degrees.The incidence of grade Ⅱ-Ⅳ RTOM,the onset time,duration and NRS score of RTOM in the observation group were significantly better than those in the control group(P<0.05,P<0.01).After radiotherapy,the levels of se-rum CRP,IL-6,IL-1β and TNF-α in the observation group were lower than those in the control group(P<0.05,P<0.01).After radiotherapy and 1 month of follow-up,the KPS score and BMI in the observation group were higher than those in the control group(P<0.05,P<0.01).CONCLUSION Yangyin Jiedu Decoction can decrease the incidence and severity of RTOM in patients with head and neck tumors,shorten its duration,improve the quality of life of patients,downregulate the level of inflammatory cytokines,and has a preventive effect on RTOM caused by radiotherapy in patients with head and neck tumors.
