Objective: To explore the association between mobile phone dependence and constipation of college students in Yunnan Province, and to provide a data reference for improving and preventing constipation in college students. Methods: A questionnaire survey was conducted among 9 960 college students from three universities in Kunming and Dali, Yunnan Province. The Self rating Questionnaire for Adolescent Problematic Mobile Phone Use was used to assess mobile phone dependence symptoms, and the questionnaire was conducted to collect the constipation information of college students. Data were analyzed with SPSS 23.0. Chi square test was used to compare the reporting rates of detection in college students with different demographic characteristics. The association between mobile phone dependence and constipation was analyzed by binary Logistic regression models. Results: The detection rate of mobile phone dependence symptoms was 30.93%, and the reporting rates of constipation was 24.46% of college students in Yunnan Province. After collcted for the demographic variables and other confounding effects, the analysis results showed that:withdrawal symptoms of mobile phone dependence( OR=1.29, 95%CI =1.09-1.54), physical and mental health impacts of mobile phone dependence ( OR=1.25, 95%CI =1.10-1.43) and craving of mobile phone dependence ( OR=1.20, 95%CI =1.06-1.36) were associated with constipation in college students( P <0.01). Conclusion Mobile phone dependence may increase the risk of constipation of college students in Yunnan Province, so health education should be strengthend.

Objective To understand the present situation of sense of coherence and resilience of junior nurses, and to analyze their correlation.Methods From July to August 2016,a total of 1484 junior nurse were selected from 10 tertiary hospitals and investigated by Sense of Coherence-13 and resilience of medical staff. Results The scores of sense of coherence and resilience were (50.24±9.40) and (52.02±11.62),and there were positive correlations among sense of coherence and resilience (r=0.197-0.462;P<0.05).Conclusions The higher the level of sense of coherence in junior nurses, the higher the level of resilience. Hence, the nurse managers should pay attention to meaningfulness which is beneficial to improve the resilience.

Objective:To compare the clinical efficacy and complications of intra-arterial chemotherapy (IAC) and intravenous chemotherapy (IVC) for unilateral advanced retinoblastoma (RB).Methods:A retrospective clinical study. From January 2020 to January 2021, 40 patients (40 eyes) unilateral group cT2 RB patients diagnosed at Baoding Children’s Hospital and Beijing Children’s Hospital were recruited in this study. There were 22 males (22 eyes) and 18 females (18 eyes). All were monocular. All the patients were assigned to two groups according to different treatment modalities they received: IVC group and IAC group. There were 26 eyes and 14 eyes, respectively. When the tumor invades the optic nerve, choroid, sclera, anterior chamber and iris, enucleation was performed. The globe salvage rate, tumor extraocular metastasis rate, solid tumor control rate, treatment-related complications and pathological high-risk factors after enucleation were observed. The globe salvage rate and solid tumor control rate were compared between the groups by chi square test.Results:The globe salvage rate of IAC group and IVC group were 88.5% (23/26) and 50.0% (7/14), respectively. Solid tumor control of IAC group and IVC group were 84.6% (22/26) and 42.9% (6/14), respectively. There were statistically significant differences in globe salvage rate and solid tumor control between the two groups ( χ 2=7.18, 7.56; P<0.05). Compared with IVC group, IAC group had less systemic complications, mild ocular and periocular side effects. Among 26 cases in IAC group and 14 cases in IVC group, 3 and 7 cases underwent enucleation respectively. The results of pathological examination showed that there were 2 cases and 3 cases with pathological high-risk factors in the two groups, respectively. During the follow-up period, 2 cases in IAC group had extraocular metastasis, there was no extraocular metastasis in IVC group. Conclusion:Compared with IVC, IAC has the advantages of high tumor control rate, high globe salvage rate, less and mild complications, however, there is still tumor recurrence.

Objective:To explore the clinical effects of the best evidence-based practice plan for rehabilitation exercises in patients undergoing surgery for lumbar spinal stenosis (LSS) .Methods:Guided by the evidence-based practice model of the Joanna Briggs Institute (JBI) Center for Evidence-Based Healthcare in Australia, the best evidence was combined with the clinical context to develop quality review indicators for clinical practice. In December 2022, a baseline review was conducted with 30 patients undergoing surgery for LSS (before evidence application). From December 2022 to February 2023, the baseline review results were analyzed to identify facilitating and obstructive factors between the current status and the review indicators, and improvement strategies were implemented based on available resources. In February 2023, another 30 patients (after evidence application) were selected to evaluate the post-application effects. The Japanese Orthopedic Association (JOA) score, Oswestry Disability Index (ODI), Tampa Scale for Kinesiophobia (TSK) score, General Self-Efficacy Scale (GSES) score, and quality of life scores were compared between the two groups at 24 hours, 1 month, 3 months, and 6 months postoperatively. The execution rate of clinical quality review indicators and the knowledge scores on rehabilitation exercises of 25 nurses before and after training were also compared.Results:There were no statistically significant differences in JOA scores, ODI, TSK scores, GSES scores, and quality of life scores between the two groups at 24 hours postoperatively ( P > 0.05). However, there were statistically significant differences in these scores at 1, 3, and 6 months postoperatively ( P< 0.01). After evidence application, the execution rate of seven clinical quality review indicators improved, and the knowledge scores on rehabilitation exercises of the 25 nurses increased significantly ( P< 0.05) . Conclusions:The evidence-based practice for rehabilitation exercises in patients undergoing surgery for LSS is safe and feasible. It standardizes evidence-based nursing practice behavior, enhances nurses' knowledge levels, effectively improves postoperative lumbar function, promotes physical rehabilitation, and enhances the quality of life.

OBJECTIVETo compare the efficacy difference between acupotomy and acupuncture in the treatment of avascular necrosis of femoral head at the early and middle stages.

METHODSThe randomized controlled prospective study method was adopted. Sixty cases of avascular necrosis of femoral head at Ficat-ArletⅠto Ⅱ stages were randomized into an acupotomy group (32 cases) and an acupuncture group (28 cases) by the third part. In the acupotomy group, the acupotomy was adopted for the loose solution at the treatment sites of hip joint, once every two weeks, totally for 3 times. In the acupuncture group,points around the hip joint were selected and stimulated with warm acupuncture therapy, once every day, for 6 weeks. Harris hip score was observed before and after treatment. The efficacy was evaluated in the two groups.

RESULTSHarris hip score was improved significantly after treatment in the two groups (both<0.05). The result in acupotomy group was better than that in the acupuncture group (<0.05). The effective rate was 90.6% (29/32) in the acupotomy group, better than 75.0% (21/28) in the acupuncture group after treatment (<0.05).

CONCLUSIONSHarris hip score and the effective rate in the acupotomy group are better than those in the treatment with routine acupuncture for avascular necrosis of femoral head at the early and middle stages.

Objective:To investigate the distribution rules of artemisia pollen and the clinical sensitization characteristics of allergic rhinitis (AR) induced by artemisia pollen in three urban and rural areas of Inner Mongolia.Methods:From March to October 2019, in 3 central cities (Chifeng, Hohhot, Ordos) and rural areas of Inner Mongolia, an epidemiological investigation method combining multi-stage stratified random sampling and face-to-face questionnaire survey was adopted to screen suspected AR patients, and skin prick test (SPT) was applied for diagnosis. At the same time, pollen monitoring was carried out in 3 areas to analyze the distribution and clinical sensitization characteristics of artemisia pollen.SPSS26.0 statistical software was used to process all the data. Chi-square test was used to compare rates among different age, sex, region and nationality, Spearman test was used to describe correlation analysis, and pairwise comparison of positive rates among multiple samples was used Bonferroni method.Results:Among the 6 393 subjects, 1 093 cases were diagnosed with AR, and the prevalence of AR was 17.10% (1 093/6 393). Among them, pollen-induced allergic rhinitis, the prevalence of PiAR was 10.97% (701/6 393), accounting for 64.14%(701/1 093).The highest incidence was in the youth group (20-39 years old), accounting for 46.94% (329/701).The diagnosed prevalence was higher in females than in males (11.35% vs. 10.64%, χ2 value 12.304, P<0.001).The prevalence rate of ethnic minority was higher than that of Han nationality (13.01% vs. 10.65%, χ2 value 6.296, P=0.008).The prevalence in urban areas was also significantly higher than that in rural areas (18.40% vs. 5.50%, χ2 value 10.497, P<0.001).There was significant difference in prevalence rate among the three regions in Inner Mongolia (6.06% in Chifeng, 13.46% in Hohhot, 16.39% in Ordos, χ2 value 70.054, P<0.001).The main clinical symptoms of artemisia PiAR were sneezing (95.58%), nasal congestion (91.73%) and nasal itching (89.30%).Allergic conjunctivitis accounted for 79.60% (558/701), chronic sinusitis for 55.63% (390/701), asthma for 23.25% (163/701).The pattern of artemisia pollen sensitization was mainly multiple sensitization, and the frequency of clinical symptoms and clinical diseases induced by hypersensitization with other allergens accounted for more than that caused by single artemisia pollen. The spread period of Artemisia pollen in the three regions was from June to October, and the peak state was in August in summer. The peak time of clinical symptoms in artemisia PiAR patients was about 2 weeks earlier than the peak time of pollen concentration, and the two were significantly positively correlated ( R=0.7671, P<0.001). Conclusion:Artemisia pollens are the dominant pollens in late summer and early autumn in Inner Mongolia, and the prevalence of artemisia PiAR is high. Controlling the spread of Artemisia pollens is of great significance for the prevention and treatment of AR.
