Objective:To analyze the risk factors for surgical site infections（SSI）in liver transplant recipients.Methods:Relevant studies on the risk factors for SSI in liver transplant recipients were searched in PubMed，Web of Science，EMbase，The Cochrane Library，CNKI，Wanfang，Vep，and the Chinese Biomedical Literature Database from inception to July 10，2023. The literature quality was assessed，and meta-analysis was performed using RevMan 5.4 and Stata 16 software.Results:A total of 10 studies involving 3 113 adult liver transplant recipients were included，and 723 cases of SSI were reported. Meta-analysis revealed that Roux-en-Y biliary reconstruction（ OR=2.60，95% CI 1.45-4.65），bile leakage（ OR=17.22，95% CI 8.48-34.96），repeat surgery（ OR=7.22，95% CI 4.25-12.26），re-transplantation（ OR=13.88，95% CI 7.71-24.97），prolonged surgical duration（ MD=0.52，95% CI 0.19-0.84），dialysis（ OR=3.44，95% CI 2.41-4.91），and extended hospital stay（ MD=11.42，95% CI 5.73-17.12）were independent risk factors for SSI in liver transplant recipients. Conclusion:The identified risk factors for SSI in liver transplant recipients include Roux-en-Y biliary reconstruction，bile leakage，repeat surgery，re-transplantation，prolonged surgical duration，dialysis，and extended hospital stay. Clinicians should enhance the assessment of these factors and take effective intervention to improve clinical outcomes for liver transplant recipients.

Objective: To investigate and analyze the amount and the type of fluid intake in spring among male college athletics in a university in Beijing, and to provide scientific basis and reference data for fluid intake-related education and formulating adequate water intake. Methods: A simple random sampling method was used to select 109 male sports crowd from a college in Beijing. The information on amount and types of fluid intake were recorded using the validated 7-day fluid specific diary. Results: The median amount of daily fluid intake among participants was 1 789 mL. The number of participants who reached the amount of adequate water intake for Chinese adult residents 60, which accounted for 55.1% of the total participants. There was difference on the amount of fluid intake among different participants after grouped by the quartiles of exercise consumption(χ2=9.20, P=0.03). There were also differences in the percentage of fluid intake reaching the recommended amount on adequate water intake(χ2=18.27, P=0.04). The median amount of plain water, dairy products, sports beverages, and other sugary beverages were 1 180, 40, 65, and 383 mL, respectively; which accounted for 67.1%, 2.2%, 3.7%, and 22.2% of daily fluid intake. There was difference on the amount of sports beverages among different participants after grouped by the quartiles of BF%(χ2=8.59, P=0.04). There was difference on the amount of sports beverages (χ2=8.25, P=0.00) and other sugar-sweetened beverages (χ2=8.57, P=0.02) among different participants after grouped by the quartiles of energy expenditure. Conclusion Among male sports population in a university in Beijing, the amount of fluid intake differed among different participants after grouped by the quartiles of exercise consumption. As the exercise consumption of participants increased, the water consumption increased. Participants mainly drink plain water, and there were differences on the types of fluid intake among participants with different BF% and different energy expenditure.

Objective: To understand the knowledge, attitudes and practices of drinking water among college students of Hebei Province, to provide evidence for health education. Methods: A total of 715 subjects were selected from a university in Baoding City, Hebei Province in March 2017 by random cluster sampling. Knowledge, attitude and behavior of drinking water among college students were investigated by self-designed questionnaires. Results: The awareness rate of water consumption of 1 500-1 700 mL was 19.0%, the awareness rate of drinking modes was 95.0%, the awareness rate of suitable drinking time was 30.1%, the awareness rate on drinking water was higher among girls and medical major sutdents (χ2=22.16, 12.49, P<0.05); the awareness rate on the relationship between insufficient drinking water and stroke, hypertension and coronary heart disease was generally low, with sophornore higher than freshman (χ2=11.10, P<0.05). The most common medium for accessing drinking water knowledge among the respondents was network (60.0%), followed by campus publicity/classroom teaching (48.3%). 99.6% of the respondents believed that drinking water was important to health, 98.3% were willing to change their drinking habits, 93.0% were willing to pay attention to drinking water education, and the proportion of female students was higher than that of male students (χ2=5.46, 6.49, 8.01, P<0.05). In real life, 48.4% of the respondents drank water on an empty stomach in the morning and 40.7% before going to bed. 45.5% of the respondents drank water when they thought of it. Conclusion College students in Hebei province are generally lack of appropriate awareness on water drinking, which varied in sex, grade and major. While the attitude towards water drinking is satisfactory, drinking behavior need to be improved.

Objective: To investigate and analyze the fluids intake, urine output and hydration status during spring among male college athletics from one university in Beijing, and to provide scientific evidence for launching targeted health education. Methods: A simple random sampling method was used to select 109 male students in college with habit of exercise.Total drinking fluids was assessed by 7-day 24-hour fluid intake questionnaire. The water from food was assessed by the duplicate portion method and the weight method. The urine samples of 24-hour was collected for 3 consecutive days, and the volume, osmolality and specific gravity of urine were measured. The energy expenditure in exercise was estimated by using the exercise plan. Results: The median drinking fluids intake, water from food, total fluids intake and urine volume were 1 789, 955, 2 701, 850 mL/d, respectively. 15.6% of the subjects were in proper hydration status, and 43.1% of the subjects were in dehydration. The differences between drinking fluids intake, water from food, total fluids intake and urine volume of subjects in the different BMI and BF% levels were not significant(P>0.05). The differences between drinking fluids intake and total fluids intake of subjects in the different energy expenditure in exercise levels were significant(χ2=9.20, 8.43, P<0.05). Conclusion Comparing with the normal college students, the drinking fluids intake and total fluids intake of male sports people were higher, the volume of urine was lower, and the hydration status was worse. The targeted health education about water intake was recommended.

The final evaluation index system of nursing counterpart support by ClassⅢ Grade A hospitals for country hospitals included three first-level indexes, hospital organizational leadership, accredited personnel management and synthetic evaluation, as well as 7 second-level indexes and 48 third-level indexes.Conclusions:This index system could be a tool for evaluating the nursing counterpart support.

Objective: To investigate the association of within-day drinking occasions with average amount consumed per drinking occasion during spring among college students in Hebei Province and to provide the basic data for the revision of quantity of consumption among Chinese residents. Methods: A total of 156 college students in Hebei Province were selected by using simple random sampling method. Information on daily amount and types of water consumption was recorded using the 7-day 24-hour recording method. The daily amount and type of drinking water by sex and BMI were analyzed and compared. Results: The daily median drinking water intake was 1 135 mL; the daily median number of drinking occasion was 6, with 34.6% of participants less than 6 drinking occasions; the median amount consumed per drinking occasion was 177 mL. The daily number of water and plain water drinking occasion of females were higher than males(χ2/Z=8.34, -2.03, P<0.05); the amount consumed per drinking occasion, the amount of plain water and beverages consumed per drinking occasion of males were higher than females(χ2/Z=23.86, -5.48, 3.70, P<0.01); The differences of the amount of plain water consumed per day among students and their BMI were of statistical significance(χ2=9.17, P=0.03), the amount of drinking water each time was positively correlated with body surface area(r=0.18, P=0.03), and frequency of drinking water was positively correlated with the amount of drinking water, negatively correlated with the amount of drinking water each time. The amount of drinking water was positively correlated with the amount of drinking water each time(r=0.30, -0.47, 0.61, P<0.01). Conclusion There is a certain proportion of unhealthy drinking behavior among college students; drinking behavior is different by sex and BMI. With the increase of drinking occasions, the amount consumed in each drinking occasion decreases, but total amount of drinking water increases.

Objective: To investigate drinking behaviors in weekdays and weekends among college students in Hebei Province during spring, and to provide references for propaganda of water drinking. Methods: A total of 156 college students in Hebei Province were selected using simple random sampling method. The survey began in March 2017. 7-day 24hour recording method was applied to record the amount and type of water drinking during for consistent consecutive 7 days, duplicate portion method was used to weigh the food consumed during the consistent consecutive 3 days and to record the water contained in the food. Results: Water intake from food among subjects during weekdays was higher than that among subjects during weekends (1 191 mL vs 1 113 mL, P<0.01). Only 21.9% and 19.9% of subjects consumed sufficient water during weekdays and weekends, according to the recommendation of China on total fluids intake, respectively. The proportion of water intake from staple food among male subjects during weekdays was lower than that during weekends (28.6% vs 31.1%). The proportion of water intake in males from porridge, water intake from soup and vegetables among subjects during weekdays were higher than those among subjects during weekends (6.8% vs 0; 141 mL vs 0 mL; 699 mL vs 647 mL). Water intake from staple food and vegetables among females during weekdays was higher than that during weekends (256 mL vs 210 mL; 559 mL vs 536 mL). There were no statistically differences on plain water, milk and beverages among subjects during weekdays and weekends(P>0.05). Conclusion Water intake from food among college students in Hebei Province during weekdays in spring is higher than that during weekends. There is discrepancy on sources of water intake from food during weekdays and weekends, while no similar difference on sources of drinking water. Proportion of college students without sufficient daily water intake during weekdays and weekends is relatively high which warrants further notice.

Objective: To analyze the urination behavior in spring among college students in Hebei Province. Methods: In March 2017, the subjects were recruited in a college in Baoding, Hebei Province. And 156 students completed the investigation. The urine samples of 24 hour was collected for 3 consecutive days by special device, and the volume, the voids and the time of urine were measured. Results: The average volume of urine per day was 1 279 mL, the average void of urine per day was 6.2, and the average volume of urine per time was 209 mL. The volume of urine and void were mainly at the time of after lunch, the volume, the proportion of the volume and void of urine were 406 mL, 31.0% and 1.7 times respectively. The volumes and the voids of urine were different in different time periods(P<0.05). The volume of urine, the proportion of the volume and the voids of urine were mainly at the time of morning, followed by the afternoon. The average volume of urine per day was 535 mL, the proportion of the volume was 44.1% and the average void of urine was 2.3, in the morning. There were significant differences in the voids of urine, the volumes of urine and the voids of urine in different time periods between boys and girls(χ2=73.71, 47.48, 34.92; 35.17, 21.30, 20.69; 37.02, 25.30, 15.32, P<0.05). The void of urine was negatively correlated with the average volume of urine per time(r=-0.61, P<0.01); the volume of urine was positively correlated with the average volume of urine per time(r=0.79, P<0.01); the void was not correlated with the volume of urine(P<0.05). Conclusion The urination behaviour of college students in Hebei Province was mainly at the time of after lunch, in the morning and in the afternoon. The college students had unhealthy urination behavior, which was in need of related health education.

Objective: To investigate the total amount and types of fluid intake among college students in Hebei Province during spring and to provide scientific basis for fluid-intake education. Methods: A simple random sampling method was used to select 156 college students from a college in Hebei Province. The information on amount and type of fluid intake was recorded using the 7-day 24-hour recording method. A separate analysis was performed on people who consumed beverages during the 7 days. Results: The median intake of plain water, milk, sugar-sweetened beverages and other beverages was 866 mL, 43 mL, 43 mL and 2 mL, respectively. The median of plain water, milk, sugar-sweetened beverages and other beverages by the beverage-consumers was 845 mL, 36 mL, 63 mL and 11 mL, respectively. The intake of plain water and sugar-sweetened beverages in male students was significantly higher(Z=2.31, 3.03; 2.31, 2.11, P<0.05), and milk consumption was lower than female students of these two groups of people(Z=-2.73, -2.23, P<0.05). The intake of other beverages in male students was higher than that of female students, but only significant among beverage-consumers(Z=3.31, P<0.01). There was no significant difference in the total amount of different fluid types among different BMI(P>0.05). Conclusion College students in Hebei Province mainly drink plain water. Sex difference is observed in the types of fluid intake.

Objective: To investigate drinking behaviors among college students in Hebei Province during 8 periods of a day(before breakfast, during breakfast, after breakfast, during lunch, after lunch, during super, after super, during night in spring, and to analyze the drinking behaviors during different time periods so as to provide the scientific reference for health progaganda of water drinking. Methods: A total of 156 college students in Hebei Province were selected using simple random sampling method. The information of frequency, types and patterns of daily water drinking during 8 time periods, including morning, afternoon and evening, during meal and non-meal time, were recorded using the 7-day 24-hour recording method. Results: During 8 time periods, the amount (325 mL) and the percentages (89.8%) of drinking water after dinner was highest(Z=774.72, P<0.01), while water drinking after lunch and dinner was more common(Z=839.05, P<0.01). The amount (439 mL) of water intake in the evening was highest(Z=45.14, P<0.01), while water intake during the afternoon and evening was more common(2.3 time on average)(Z=40.34, P<0.01). About 54.2% of participants drank water during meal, while 99.2% drank water during non-meal time. The amount of water intake, the percentage of total daily water intake and the number of water intake during meal time was lower than those during non-meal time(Z=-14.58, -15.07, P<0.01). Conclusion Drinking behaviors in different time period among college students in Hebei Province during spring varies significantly. The amount of water intake in non-meal time is generally higher than that in meal time.
