OBJECTIVETo analyze the epidemiological characteristics of hospitalized children with burn injuries in Fujian Medical University Union Hospital, so as to provide evidence to complete an adequate, timely, and effective prevention and treatment system of children with burn injuries.

METHODSMedical records of children with burn injuries, aged 14 and under, hospitalized in the Department of Burns from July 2012 to June 2015 were collected. Data of gender and age, location and cause of injury, time of injury, state of injury, admission time after injury, first aid, length of hospital stay, and treatment and so on were recorded. They were divided into 4 age brackets: less than or equal to 1 year old, more than 1 year old and less than or equal to 3 years old, more than 3 years old and less than or equal to 7 years old, more than 7 years old and less than or equal to 14 years old, then gender and cause of injury of children in the 4 age brackets were analyzed. Admission months of the children were divided into spring (March to May), summer (June to August), autumn (September to November) and winter (December to February of the following year), and then the cause of injury of children in each season was analyzed. Severities of male and female children, length of hospital stay of children with different causes of injury were analyzed. Data were processed with chi-square test, Wilcoxon rank-sum test.

RESULTSOut of 2 608 inpatients with burn injuries, 1 407 children with burn injuries, aged 14 and under, accounting for 53.9%, were admitted in the recent 3 years. The ratio of male to female was 1.6 ∶1.0. Children more than 1 year old and less than or equal to 3 years old ranked the largest number (68.3%, 961/1 407) in the 4 age brackets. There was statistically significant difference in constituent ratios of gender of children among the 4 age brackets (χ(2)=11.00, P=0.012). One thousand three hundred and seventy-two children were burned indoors (97.5%), while 35 children were burned outdoors (2.5%). Scalding with hot fluids was the most common cause of burn (95.0%, 1 337/1 407). There was statistically significant difference in constituent ratios of injury cause of children among the 4 age brackets (χ(2)=107.23, P<0.01). There was statistically significant difference in constituent ratios of injury cause of children more than 7 years old and less than or equal to 14 years old compared with those of the other 3 age brackets (with χ(2) values from 12.88 to 119.85, P values below 0.01). Most burn accidents occurred between 17: 00-20: 59 (33.5%, 472/1 407). Burns were more likely to happen in April to October. July (10.4%, 146/1 407) and August (10.5%, 148/1 407) were the crest-time. Most of the children were burned in summer (35.3%, 496/1 407). There was statistically significant difference in the injury cause of children among each season (χ(2)=14.61, P=0.024). The burn degrees of male and female children were mainly mild or moderate, and there was no statistically significant difference in the severity (Z=-0.39, P>0.05). The trunk was the most involved anatomic site (61.1%, 859/1 407). Most of children were admitted to hospital within 2 hours post burn (79.7%, 1 121/1 407). Majority of children were taken off clothes as first aid on spot or did not receive any treatment. Most of the children were discharged within 2 weeks after admission (80.0%, 1 126/1 407). There was statistically significant difference in length of hospital stay of children with causes of hot liquid scald, flame burn, electric burn, high temperature solid burn, chemical burn (χ(2) =17.33, P=0.002). Most of the children were treated with non-surgical methods, and the majority of the children got better condition or totally recovered and then discharged.

CONCLUSIONSThe majority of hospitalized children with burn injuries in our unit are young boys in preschool period, who were burnt by hot fluid at the time of dinner and bathing at home during summer. So we should make more effort on popularization of prevention about burn.

Jerusalem artichoke tubers with inulin as major component are potential feedstock for fuel ethanol production, and Kluyveromyces cicerisporus Y179 expressing high level of inulinase is suitable for ethanol production with this feedstock by simultaneous saccharification and fermentation approach. In this article, the impact of inoculum, aeration and temperature on ethanol production by the yeast was studied. The experimental results illustrated that inoculum with different levels and seed collected at different cultivation times had negligible effect, while anaerobic conditions enhanced ethanol production, and more ethanol was produced by the yeast at 30 degrees C than at 37 degrees C or 42 degrees C. The medium using Jerusalem artichoke tuber meal as sole component with 22% (W/V) total sugars was inoculated with 36 h-precultured seed at 10% (V/V), and the batch fermentation was conducted in a 5 L fermentor at 30 degrees C with a stirring speed of 300 r/min under anaerobic conditions. After 144 h, 12.3% (V/V) ethanol was produced and the yield of ethanol from sugars was 86.9% of its theoretical one, with 93.6% sugars consumed. These results indicate that K. cicerisporus Y179 is a promising candidate for industrial ethanol production using Jerusalem artichoke tuber feedstock.

Objective To understand the status quo of midwives' core competency in Fujian Province and analyze its influencing factors.Methods A total of 374 midwives from 13 hospitals in Fujian Province were surveyed by the midwife core competency scale.Results The average score of midwives' core competency were(3.96±0.54).The scores of vocational literacy,postnatal care skills and health care skills during pregnancy were relatively high.The scores of public health care knowledge,public health care skills and women's health knowledge were relatively low.The scores of core competence for junior,senior and expert abilities for midwives were (4.03±0.55),(3.78±0.59)and (3.54±0.75),respectively.In seven dimensions,the scores for skills were all higher than those for knowledge.Multivariate stepwise regression analysis showed that years of working,hospital grade,marital status and form of employment were influencing factors of midwives' core competency (P＜0.05).Conclusion The core competence of midwives in 13 hospitals in Fujian Province was generally at the middle level.The junior ability was satisfactory,and the senior and expert abilities should be improved.Midwives who were newly employed,working in primary institutes,non-institution personnels should be paid more attention in order to promote midwives' core competency holistically.

Objective:To investigate the risk factors of spinal cord injury after FET for ATAAD.Methods:We analyzed perioperative data of 111 patients with ATAAD who underwent FET in the First Affiliated Hospital of Nanjing Medical University from January 2020 to October 2021.Results:Eleven(9.9%)of 111 patients had postoperative spinal cord injury, which showed varying degrees of paralysis or paraplegia. There was no significant difference in age, sex, medical history, cardiopulmonary bypass time, aortic cross-clamping time, circulatory arrest time and FET length between spinal cord injury group and non-spinal cord injury group( P>0.05). Univariate analysis showed that aortic true lumen away from the spinal side( P<0.001) and the number of segmental arteries originating from the true lumen<3 in T9-L3( P<0.001), left subclavian artery involvement( P<0.05) and stent coverage at T8 or beyond( P<0.05) was associated with postoperative spinal cord injury. Multivariate Logistic analysis showed that aortic true lumen away from the spinal side( P<0.001) and the number of segmental arteries originating from the true lumen<3( P<0.001) in T9-L3 and left subclavian artery involvement( P<0.05) were independent risk factors for postoperative spinal cord injury. Conclusion:The pathogenesis of spinal cord injury is complicated. This study suggests that the occurrence of spinal cord injury is significantly related to aortic true lumen away from the spinal side and the number of segmental arteries originating from the true lumen<3 in T9-L3 and left subclavian artery involvement. It is of great clinical significance to identify the high risk factors of postoperative spinal cord injury as early as possible.

OBJECTIVE To explore standardized evaluation process for clinical comprehensive evaluation of blood lipid- regulating drugs and perform rapid assessment of clinical comprehensive evaluation of blood lipid-regulating drugs with different mechanisms so as to provide reference for the drug catalogue selection and rational drug use of medical institutions. METHODS Referring to guidelines and consensus such as the guideline for the management of comprehensive clinical evaluation of drugs， the methods such as literature research， expert interviews， and Delphi expert consultation were used to establish a multi-dimensional and multi-criteria clinical comprehensive evaluation index system and quantitative scoring table for blood lipid-regulating drugs around the two main lines of technical evaluation and policy evaluation. Then 13 blood lipid-regulating drugs with different mechanisms in 21 third-grade class-A medical institutions from five provinces and regions of Northwest China were scored from both technical and policy dimensions to form a comprehensive evaluation result. RESULTS The clinical comprehensive evaluation index system and corresponding rapid evaluation quantitative scoring table were constructed for blood lipid-regulating drugs in the five northwest provinces and regions. The technicalevaluation section included 6 primary indicators， 13 secondary indicators， and 34 tertiary indicators， totaling 110 points. The policy evaluation section included 4 primary indicators and 6 secondary indicators， with a total score of 40 points （30 points for some drugs） and a total score of 150 points （or 140 points）. The scoring results showed that the highest score was atorvastatin， followed by rosuvastatin and simvastatin. CONCLUSIONS Statins are still the cornerstone of drug therapy for patients with dyslipidemia； the rapid evaluation quantitative scoring table constructed in this study is comprehensive， systematic and operable. The evaluation process in this study can provide empirical references for other groups to exploring the standardized path and quality control mechanism of clinical comprehensive evaluation of drugs.
