Mean follow-up was 10.3 months.Results　Three to 30 droplets of perfluorodeclin liquid were found in the anterior chambers in 9 eyes. There was no corneal complication or inflammatory reactions or blood vessel invasion into the corneal stroma or increased intraocular pressure.Conclusion　Residual perfluorodeclin liquid droplets in the anterior chamber are well tolerated and do not induce corneal damage or ocular inflammation.

Objective To investigate the effect of narrative medicine mode in perioperative medical and nursing care for patients underwent radical nephrectomy. Methods A total of 124 patients received radical nephrectomy from February 2014 to October 2016 were selected and divided into experimental group and control group by block randomization grouping method with 62 cases each. Narrative medical treatment and care was applied in experimental group while control group received conventional treatment and care. The psychological status and social support of the patients were evaluated by Zung Self-rating Anxiety Scale(SAS), Self-rating Depression Scale (SDS) and social support rating scale(SSRS), as well as rehabilitation indexes including complications, first feeding time, hospitalization time, costs, etc. Results Anxiety and depression status were existed in both experimental and control groups before operations, and there were no significant difference in all pre-operative scales between two groups (P>0.05). The score of SAS, SDS, SSRS was (44.71 ± 4.67), (40.84 ± 4.05), (43.21 ± 3.60) points after operation and (54.98 ± 5.93), (46.52 ± 5.07), (31.87 ± 3.22) points before operation in experimental group. The score of SAS, SDS, SSRS was (53.24±5.97), (44.63±4.37), (32.61± 2.72) points after operation and (54.92 ± 5.83), (46.53 ± 4.89), (32.16 ± 2.48) points before operation in control group. Significant differences were found between before and after operation in experimental group (t=18.73, 8.85, 18.18, all P<0.01). However, no significant difference could be found between before and after operation in control group (t=1.590, 1.400, 1.910, P>0.05). After operation, the complications, first feeding time, hospitalization time and costs was 22.58%(14/62), (2.50±0.92) d, (11.16±3.72) d, (24.6±4.0) thousand yuan in experimental group, which was 48.39%(30/62), (3.98 ± 1.44) d, (15.48 ± 5.44) d, (40.2 ± 3.1) thousand yuan in control group. Significant differences were found between experimental group and control group (χ2=9.02, t=2.07, 8.06, 3.93, P<0.05 or 0.01). Conclusions Narrative medicine mode can provide medical care filled with respect, empathy, and humanistic concern, andimprove patients′psychological status, thus promoting rehabilitation.

Objective: To explore the relationships among social support, depression, anxiety and suicide ideation among middle school students in rural areas of south Sichuan Province so as to provide a scientific basis for promoting middle school students’ mental health and reducing suicide ideation. Methods: A sum of 2 217 students of grade 7 and 10 from 2 township middle schools in mountainous areas of Zizhong County, Sichuan Province, were investigated by means of typical sampling and cluster random sampling. Social Support Rating Scale (SSRS), Self-rating Scale for Depression (SDS), Self-rating Anxiety Scale (SAS) and Self-compiled adolescent health questionnaire were used to measure suicidal ideation, and structural equation model was used for statistical analysis. Results: The depression score of middle school students was (13.51±12.57), and the self-rating scale for Depression score of girls was (14.61±12.67), higher than that of boys (12.24±12.34). The SSRS score of Social Support Rating Scale of junior high school students was (35.49±5.88), which was higher than that of senior high school students (34.70±5.43), and the differences were of statistical significance(t=4.46, 2.67, P<0.05). The results of structural equation model showed that depression and anxiety directly affected suicidal ideation, and the standardized effects were respectively 0.11 (95%CI=0.06-0.16) and 0.09(95%CI=0.05-0.14). Depression and anxiety were the intermediate variables in the relationship between social support and suicidal ideation, and the mediating effects were respectively -0.46(95%CI=-0.51--0.41) and -0.21(95%CI=-0.27--0.16). Studying period could play a mediating role in the indirect effect made by social support on suicide ideation through anxiety. Conclusion Anxiety and depression have significant mediating effect on the relationship between social support and suicidal ideation among middle school students in rural areas of south Sichuan province. Anxiety and depression intervention are important measures to reduce suicide ideation among low social supporters.

Objective:To investigate the prevalence and influencing factors of mental health status and internet-surfing behavior among rural adolescents in Sichuan province,and explore the mutual effects between mental health status and internet-surfing behavior.Methods:Totally 2745 junior and senior high school students of grade seven and grade ten from two rural schools were selected.Mental health status,self-esteem and social support of students were assessed with Mental Health Inventory of Middle-school students (MMHI),Rosenberg self-esteem scale (SES) and social support rating scale (SSRS) respectively.Demographic characteristics,internet-surfing behavior were obtained using cross-sectional survey.Non-recursive structural equation model was applied to analyze the effects of other variables on mental health status and internet-surfing behavior and the mutual effects between them.Results:The mean score of MMHIwas (2.1 ±0.7),and the dimensions including academic stress (2.4 ±0.9),emotional instability (2.4 ±0.8) and anxiety (2.4 ± 1.0) got the top three.The total prevalence of long-time internet-surfing was 32.8％ (899/2745).The structural equation model showed that female and increasing age had positive effects on score of MMHI (β =0.058,0.058,P ＜ 0.001),and male and increasing age positively influenced internet-surfing behavior (β =-0.171,0.149,P ＜ 0.001).The scores of SES and S SRS were directly negatively related to the score of MMHI (β =-0.300,-0.263,P ＜ 0.001),and indirectly negatively affect internetsurfing behavior through the mediating effect of mental health (βi =-0.074,-0.065,P ＜ 0.010).The score of MMHI had positively effects on long-time internet-surfing behavior (β =0.246,P ＜ 0.001),and long-time internetsurfing behavior had positively effects on the score of MMHI in reverse (β =0.008,P ＜ 0.001),but much weaker.Conclusion:There are mild mental health problem among rural adolescents,and internet-surfing behaviors are prevalent among this population.Poor mental health and long-time internet-surfing behavior are risk factors mutually.

Objective:To explore the effects of etoricoxib combined with sodium hyaluronate on pain and inflammatory factors in patients with knee osteoarthritis (KOA).Methods:A total of 106 KOA patients admitted to Zhujiang Hospital of Southern Medical University were selected as the research objects from March 2018 to October 2020, and they were divided into a control group and a study group using a random number table method, with 53 cases in each group. The control group was treated with sodium hyaluronate, and the study group was treated with etoricoxib on the basis of the control group. The effects of both groups were observed after continuous treatment for 4 weeks. The clinical efficacy and changes of knee joint function, pain and inflammatory factors before and after treatment were compared between the two groups, and the occurrence of adverse reactions during the treatment period was recorded.Results:The total effective rate of the study group was higher than that of the control group: 92.45%(49/53) vs. 77.36%(41/53), the difference was statistically significant ( P<0.05). The American Knee Association score (AKS) and Lysholm score after treatment in the two groups were higher than before treatment ( P<0.05), and the AKS score and Lysholm score in the study group after treatment were higher than control group: (171.84 ± 24.16) scores vs. (159.09 ± 22.21) scores, (81.62 ± 14.76) scores vs. (75.41 ± 13.58) scores, the difference was statistically significant ( P<0.05). The visual analogue score (VAS) of pain after treatment in the two groups was lower than before treatment, and the VAS score of the study group after treatment was lower than the control group: (3.01 ± 0.54) scores vs. (3.45 ± 0.64) scores. the difference was statistically significant ( P<0.05). The levels of interleukin-1β (IL-1β), matrix metalloproteinase-3 (MMP-3) and matrix metalloproteinase-9 (MMP-9) after treatment in the two groups were lower than before treatment, TIL-1β, MMP-3, and MMP-9 of the study group after treatment were lower than the control group: (56.38 ± 9.67) μg/L vs. (62.19 ± 10.73) μg/L, (91.56 ± 15.18) μg/L vs. (98.09 ± 16.74) μg/L, (30.46 ± 5.59) μg/L vs. (35.03 ± 6.27) μg/L, the difference was statistically significant ( P<0.05). There was no statistically significant difference in the incidence of total adverse reactions between the two groups ( P>0.05). Conclusions:Tocoxib combined with sodium hyaluronate in the treatment of KOA can improve the clinical efficacy, improve knee joint function, relieve pain, reduce the level of inflammatory factors, and have good safety.

OBJECTIVETo analyze the status of maternal health behaviors and it's risk factors for Yi-nationality women in poor rural areas of Sichuan province.

METHODSIn 2012, multi-stage stratified cluster sampling method was used to select 14 villages of two poor counties in Liangshan Yi-nationality autonomous prefecture Sichuan province. At least 10 women who have infants aged 0-12 months were selected in each simple villages, a total of 284. The structured questionnaire was developed on the basis of the theory of reasoned action. Yi-nationality female college students were trained as investigators. Research indicators included prenatal care rate, hospital delivery rate, postpartum examination rate, socio-demographic characteristics, maternal health care knowledge. χ² test was used to compare the differences of above indicators among different groups. The structural equation model were used to statistical analyze.

RESULTSIn the 284 subject women, 51.7% (147/284) women owned more than 2 children, 41.6% (118/284) women were more than 30 years old, 87.3% (248/284) women were illiteracy. The prenatal care rate was 69.7% (197/284), the hospital delivery rate was 26.8% (76/284), and the postnatal check rate was 22.9% (65/284). The influence factors of maternal health behaviors included the number of children, age and education (χ² were 10.92, 13.24, 9.58; P values were 0.027, 0.004, 0.008, respectively).The structural equation model analysis results showed that the maternal health behaviors were directly or indirectly affected by subjective norms (β = 0.236, P < 0.001), women's cognition (β = 0.226, P = 0.020) and women's attitudes on maternal health behavior (β = 0.157, P = 0.001). Among subjective norms, women have high compliance to their husbands (β = 0.850, P < 0.001), their peers (β = 0.708, P < 0.001), and their mothers-in-law (β = 0.636, P < 0.001).

CONCLUSIONThere were still serious problems in maternal health behaviors for Yi-nationality women in poor rural areas. The main factors included not only the women's cognition and attitudes for maternal health, but also the attitudes of important social relationships.

Objective: To verify the applicability of the theory of planned behavior(TPB) in the physical exercise behaviors of rural adolescents in Sichuan Province, and to explore the possible influencing factors of physical exercise behaviors, and to provide a theoretical basis for further effective intervention measures. Methods: A total of 2 302 students were selected from grade seven and grade ten of two rural middle schools in Zizhong, Sichuan Province. The survey was conducted with a structured questionnaire. Using TPB as the research framework and basis, the structural equation model was constructed for analysis. Results: Lack of physical exercise was 1 527(66.3%).Physical exercise behavior was statistically different among schools, grades(t=-7.40，-2.90，10.90,P<0.05)， and genders. Based on TPB, the structural equation model was established and corrected to obtain the revised model, and the fitting index GFI=0.93, CFI=0.94, NFI=0.94, TLI=0.93, IFI=0.94,RMSEA=0.07, indicating the model fitted good. Exercise intention directly affected exercise behaviors. The standardized effect was 0.45(95%CI=0.39-0.52). Subjective norms and perceived power were the main two mediators of the relationship between value evaluation and exercise intention. The standardized effect values were 0.66(95%CI=0.57-0.73), 0.23(95%CI=0.16-0.93)(P<0.01). Conclusion There is serious lack of physical exercise in rural adolescents in Sichuan Province. TPB has a good applicability for physical exercise in rural adolescents in Sichuan Province. Subjective norm is the most important factors to promote exercise intentions.

Objective To investigate the effects of early ambulation on general comfort of patients undergoing retroperitoneal laparoscopic adrenalectomy. Methods From July 2013 to September 2014, 153 patients in our hospital, who underwent retroperitoneal laparoscopic adrenalectomy were randomly divided into control (n=78) and experimental groups (n=75). Early ambulation intervention was taken in the experimental group. Concretely, the patients were educated with early ambulation knowledge before operation, then they were evaluated for early ambulation 6 hours post operation. Finally, the qualified patients received early ambulation intervention and executed the corresponding ambulation program 8-24 hours after operation. Whereas, patients in the control group could decide their ambulation time all by themselves. Simultaneously, the time of first ambulation was compared between two groups and general comfort questionnaires ( GCQ ) were applied to evaluate the comfort status of the patients. Results The time of first ambulation was ( 12. 8 ± 5. 0 ) h in experimental group while it was (27. 9 ± 11. 8)h in the control group (t=10. 233,P<0. 01). The GCQ score post surgery in the experimental group was (89. 2 ± 12. 4), which was significantly higher than (73. 5 ± 10. 4) in the control group ( t = 8. 498, P < 0. 01 ). Conclusions Early ambulation of patients undergoing retroperitoneal laparoscopic adrenalectomy can effectively improve their general comfort status and promote their rapid recovery.
