RESUMO
OBJECTIVES@#To construct a quantitative index system with the integrated medical and nursing care assessment for the elderly service needs, this system can assess the cost of medical and care services accurately and objectively, so as to provide scientific basis for the allocation of old-age service resources in China.@*METHODS@#Based on the survival needs of the Existence, Relation and Growth theory, an index system is constructed through literature analysis, group discussion, and expert correspondence. Analytic hierarchy process was used to determine the weights of indicators at all levels. The 3-grades service items corresponding to each index were quantified through the measurement of working hours, and the medical and nursing care needs of 624 disabled/demented elderly people over 60 years old in Changsha were investigated to evaluate their reliability and validity.@*RESULTS@#The authoritative coefficients of the 2 rounds of expert correspondence were 88.5% and 88.6%, respectively, and the opinion coordination coefficients were 0.159 and 0.167, respectively. The final quantitative evaluation index system included 4 first-level indicators, 17 second-level indicators, and 105 third-level indicators. The service time of doctor ranged from 6.01 to 22.64 min, the service time of nurses ranged from 0.77 to 24.79 min, and the service time of caregiver ranged from 0.12 to 51.88 min. The Cronbach's αcoefficient was 0.73, the split-half reliability was 0.74, the content validity was 0.93, and the calibration validity was 0.781.@*CONCLUSIONS@#The quantitative evaluation index system of medical and nursing service need for the elderly can be used to accurately evaluate the medical and nursing service need.

Objective:To investigate the preventive effect of Xiyanping injection on radioactive esophagitis in patients with radical radiotherapy and chemotherapy for esophageal cancer.Methods:A total of 70 patients with esophageal cancer undergoing radical radiotherapy and chemotherapy were selected from the Department of Radiation Oncology of Jiangsu Provincial People′s Hospital from January to September 2020. They were divided into experimental group ( n=35) and control group ( n=35) according to random number table method. The control group received standard concurrent radiotherapy and chemotherapy, and the experimental group received concurrent radiotherapy and chemotherapy combined with Xiyanping. The white blood cell count, neutrophil count, procalcitonin (PCT) and interleukin-6 (IL-6) levels before and after treatment were compared between the two groups, as well as the occurrences of radioactive esophagitis and radioactive pneumonia during radiotherapy. Results:Before treatment, there were no significant differences in white blood cell count [4.57 (2.52)×10 9/L vs. 5.59 (2.23)×10 9/L] and neutrophil count [2.95 (1.66)×10 9/L vs. 3.69 (1.56)×10 9/L] between the control group and experimental group ( Z=1.44, P=0.151; Z=1.52, P=0.130). After treatment, there were no statistically significant differences in white blood cell count [4.28 (2.50)×10 9/L vs. 4.25 (1.88)×10 9/L] and neutrophil count [2.99 (2.50)×10 9/L vs. 2.94 (1.61)×10 9/L] between the two groups ( Z=0.67, P=0.503; Z=0.69, P=0.489). There were no statistically significant differences in white blood cell count and neutrophil count between the patients after treatment and before treatment in the two groups ( Z=0.77, P=0.443; Z=1.08, P=0.279; Z =1.06, P=0.289; Z=0.68, P=0.495). Before treatment, there were no statistically significant differences in serum inflammation indexes PCT [0.02 (0.03) μg/L vs. 0.02 (0.05) μg/L] and IL-6 [0.04 (0.21) μg/L vs. 0.04 (0.12) μg/L] between the two groups ( Z=0.70, P=0.482; Z=0.77, P=0.439). After treatment, there were statistically significant differences in serum inflammation indexes PCT [0.06 (0.17) μg/L vs. 0.03 (0.08) μg/L] and IL-6 [0.10 (0.25) μg/L vs. 0.01 (0.08) μg/L] between the two groups ( Z=2.08, P=0.038; Z=2.92, P=0.003). There were no statistically significant differences in serum inflammation indexes PCT and IL-6 in the experimental groups after treatment compared with before treatment ( Z=1.20, P=0.230; Z=1.19, P=0.235). In the control group, the serum inflammation index PCT level increased after treatment compared with before treatment, with a statistically significant difference ( Z=2.82, P=0.005), and the serum inflammation index IL-6 level increased compared with before treatment, but with no statistically significant difference ( Z=1.41, P=0.158). During the treatment, the incidence of radioactive esophagitis in the two groups was mainly grade Ⅰ-Ⅱ, with 24 cases in the control group and 28 cases in the experimental group. There were 8 patients with grade Ⅲ-Ⅳ radioactive esophagitis in the control group and 1 in the experimental group. There was a statistically significant difference in the occurrence of radioactive esophagitis between the two groups ( χ2=10.34, P=0.035). During the treatment period, most patients with radioactive pneumonia were rated as grade 0. There were 10 cases of mild radioactive pneumonia (grade Ⅰ-Ⅱ) in the control group had and 6 cases in the experimental group. There were 2 cases of grade Ⅲ radioactive pneumonia in the control group and experimental group respectively. There was no grade Ⅳ radioactive pneumonia in either group. There was no significant difference in radioactive pneumonia between the two groups ( χ2=1.34, P=0.720). Conclusion:Xiyanping injection can prevent the rise of serum inflammatory index PCT and reduce the severity of radioactive esophagitis in patients with esophageal cancer after treatment.
RESUMO
Objective:To understand the attitudes and behaviors status of injury prevention among urban residents' injury prevention in Changsha City and to provide evidence for urban residents' injury prevention.Methods:A stratified random sampling was conducted to extract 504 residents from 8 communities in 2 urban districts of Changsha City.

RESUMO
OBJECTIVES@#To investigate the status and the related factors of nursing behaviors for pressure injury, and to provide the evidence for standardizing pressure injury management.@*METHODS@#A total of 1 039 clinical nursing staff from 4 general hospitals in Changsha from December 1 to 30, 2017 were selected by a stratified random sampling procedure. Nurses' demographic information such as age, gender, title, educational attainment, and department were collected. We investigated the status of nursing behaviors on pressure injury by a self-designed questionnaire, assessed nurses' knowledge of pressure injury and nurses' attitude of pressure injury using the Pressure Ulcer Knowledge Test and Attitude towards Pressure Ulcer Prevention Instrument, respectively, compared the nursing behaviors on pressure injury with different backgrounds, used multiple linear regression to analyze the influential factors for nursing behaviors on pressure injury, and conducted the Pearson correlation analysis for nurses' knowledge, attitude, and behaviors on the pressure injury.@*RESULTS@#The overall nursing behaviors score on pressure injury was 155.96±17.29. The 5 dimensional scores from high to low were: risk assessment (4.42±0.49), prevention actions (4.40±0.50), risk understanding (4.35±0.52), injury assessment and interventions (4.27±0.55), and health education (4.25±0.63). A significant difference was found in the nursing behavior scores of pressure injury among ages, lengths of service, education, and training times (all ˂0.05). There was no correlation between nurses' knowledge and behaviors (=0.606). The nurses' attitude was positively correlated with their behaviors (=0.307, ˂0.001), and the nurses' knowledge was also positively correlated with their attitudes (=0.212, ˂0.001). The results of multiple linear regression showed that the length of service (≤5 years), training times (1-2 times), education (diploma or below), the scores of nurses' knowledge, and the scores of nurses' attitude were independent influencial factors of nurses' behaviors on pressure injury.@*CONCLUSIONS@#The nursing staff in the general hospital of Changsha has a high level of nursing behaviors on pressure injury, and they has good sense of responsibility and confidence. However, personal competence in pressure injury is insufficient and still needs to be improved. The nursing managers should focus on the nurses' attitude and training frequency, increasing the experience in nursing the pressure injury and practical level, and arouse the highly educated nurses' enthusiasm and sense of accomplishment to prevent pressure injury, thus reducing the incidence of pressure injury.

Objective To study the effect of pirfenidone (PFD) on the transformation of rat corneal stromal cells into fibroblasts in vitro and further explore the anti-fibrotic effect of PFD. Methods The corneal stromal cells from SD rat was isolated and cultured ,and was determined by vimentin stain. The experiment was divided into control group(DMEM+10%FBS),TGF-β1 group(2 ng/mL TGF-β1+DMEM+10%FBS)and PFD group(1 mg/mL PFD+ 2 ng/mL TGF-β1+DMEM+ 10%FBS). Cell proliferation was detected by CCK-8 assay. Collagen Ⅰ,Collagen Ⅲ,Keratocan and CD99 expression were detected by Western blot. Results Compared with control group and TGF-β1 group,the cell proliferation were significantly decreased in PFD group(P<0.05). Western blot showed that PFD can up-regulated Collagen Ⅰand Keratocan but down-regulated Collagen ⅢCD90 expression(P < 0.05). The ratio of Collagen Ⅲ/Collagen Ⅰ in PFD group was lowest in all groups(P < 0.05). Conclusion PFD can resistant fibration in corneal stromal cells may through the inhibition of TGF-β ,which affect the collagen synthesis and Keratocan,CD90 expression.
