AIM:To analyze the association between mobile phone addiction and high myopia among college students.METHODS:We conducted a cross-sectional questionnaire survey in December 2022 on all students of a university in Shaanxi Province, and the questionnaire included socio-demographic characteristics, mobile phone addiction, high myopia, and lifestyle. Binary Logistic regression model was used to analyze the association between mobile phone addiction and high myopia among college students.RESULTS:A total of 19 952 college students were included. The prevalence of high myopia was 7.31%. The rate of mobile phone addiction was 25.68%, and the mobile phone addiction score was 37.59±13.38. The incidence of high myopia among college students with mobile phone addiction was higher than non-mobile phone addiction(P<0.001). After adjusting for socio-demographic characteristics and lifestyle, the risk of high myopia among college students with mobile phone addiction was 1.274 times(95%CI:1.131-1.434)higher than non-mobile phone addiction. For each point increase of total mobile phone addiction score, withdrawal symptoms score, salience score, social comfort score, and mood changes score, the risk of high myopia among college students increased by 0.9%(95%CI:1.005-1.013), 2.0%(95%CI:1.010-1.030), 2.6%(95%CI:1.010-1.043), 4.8%(95%CI:1.030-1.066), and 3.3%(95%CI:1.014-1.052), respectively.CONCLUSION:Mobile phone addiction is significantly associated with the increased risk of high myopia among college students, and early intervention of mobile phone use may reduce the risk of high myopia among college students.

Pancreatic cancer patients are at the highest risk of malnutrition among all cancer patients,and radiochemotherapy may further exacerbate the risk of malnutrition in these patients.Malnutrition can reduce the therapeutic efficacy of radiochemotherapy and increase adverse reactions,thereby adversely impacting patients'quality of life and prognosis.Consequently,nutrition intervention is particularly crucial in the management of pancreatic cancer.Researches have shown that nutrition intervention can effectively ameliorate cachexia associated with pancreatic cancer,reduce the risk of malnutrition,and thereby maintain the sensitivity and tolerance to radiochemotherapy,alleviate adverse reactions,and reduce the complications of adjuvant therapy and surgical treatment.The combination of nutrition intervention and radiochemotherapy can disrupt the metabolism of pancreatic cancer and inhibit tumor growth,reduce the hospitalization rate of patients,and improve their quality of life.This review discusses the methods of nutritional assessment,nutrition intervention strategies for pancreatic cancer patients,and the impact of nutrition intervention on the efficacy and adverse reactions of radiochemotherapy in pancreatic cancer patients.

Objective:To explore the clinical characteristics and predictors of severe acute pancreatitis complicated with acute respiratory distress syndrome (SAP-ARDS).Methods:Clinical data of consecutive 313 SAP patients hospitalized from January 2000 to January 2020 in Peking Union Medical College Hospital, were retrospectively analyzed, including 258 cases with ARDS (ARDS group) and 55 cases without ARDS (non-ARDS group). According to the severity of ARDS, ARDS group were further divided into mild ARDS group (165 cases) and moderate to severe ARDS group (93 cases). Clinical symptoms, laboratory examination and imaging results, ICU admission time and clinical outcome, as well as the local and systemic complications, acute physiology and chronic health evaluation (APACHEⅡ) within 24 h after admission, bedside index for severity in acute pancreatitis (BISAP), CT severity index (CTSI), sequential organ failure assessment (SOFA) and quick sequenctial organ failure assessment(qSOFA) score were recorded. Univariate and multivariate logistic regression were performed to analyze independent risk factors of SAP complicated with moderate to severe ARDS. Receiver operating characteristics curves (ROC) was drawn to calculate area under the ROC curve (area under curve, AUC) and evaluate the performance of WBC and hsCRP in predicting SAP complicated with moderate to severe ARDS, and assess the performance of APACHEⅡ, BISAP, CTSI, SOFA and qSOFA scores in predicting SAP-ARDS endotracheal intubation.Results:The ICU length of stay and mortality rate of SAP-ARDS patients were significantly higher than those without ARDS [(8.3±11.6 day vs 5.7±7.7 day, 12.4% vs 3.6%, all P value <0.05)]. Univariate analysis showed that elevated WBC ( OR 4.52, 95% CI 1.64-12.4) and hsCRP ( OR 3.69, 95% CI 1.29-10.48) on admission were independent risk factors for moderate to severe ARDS with SAP. The AUC of WBC and hsCRP for predicting SAP with moderate to severe ARDS at admission were 0.651(95% CI 0.532-0.770) and 0.615 (95% CI 0.500-0.730), respectively. The predicted cut-off values (Cut-off values) were 17.5×10 9/L and 159 mg/L, respectively, and the sensitivity was 53.1% and 78.1%, the specificity was 78.1% and 48.4% respectively. The area under the ROC curve for APACHEⅡ, BISAP, CTSI, SOFA, and qSOFA score 24 h after admission in the early prediction of endotracheal intubation were 0.739 (95% CI 0.626-0.840), 0.705 (95% CI 0.602-0.809), 0.753 (95% CI 0.650-0.849 ), 0.737 (95% CI 0.615-0.836) and 0.663 (95% CI 0.570-0.794), and the optimum Cut-off values were 14 points, 3 points, 5 points, 7 points, 2 points, and the sensitivity and specificity for these predictors were 58.8% and 81.4%, 79.4% and 60.0%, 73.5% and 67.1%, 38.2% and 98.6%, 45.5% and 83.3%, respectively. Conclusions::Elevated blood WBC and hsCRP on admission were independent risk factors for moderate to severe ARDS in SAP. APACHEⅡ≥14, BISAP≥3, CTSI≥5, SOFA≥7, or qSOFA≥2 within the 24 h admission indictaed that the risk of SAP patients to receive endotracheal intubation was high.

Objective:To explore the effects of standardized enteral nutrition process in critically ill patients.Methods:We retrieved PubMed, EMBASE, MEDLINE, WanFang Data, China National Knowledge Infrastructure (CNKI) and China Biology Medicine (CBM) by computer to collect literatures on effects of standardized enteral nutrition process in critically ill patients from the establishment of database to May 31, 2019. RevMan 5.3 was used to statistical analysis.Results:Finally, 11 articles were included. Meta-analysis results showed that compared with conventional care, the standardized enteral nutrition process could increase the calorie compliance rate of critical ill patients on the seventh day [ OR=8.18, 95% CI (4.91, 11.45) , P<0.01], and reduce the incidence of feeding intolerance symptoms [ OR=0.36, 95% CI (0.23, 0.57) , P<0.01]. However, the standardized enteral nutrition process did not show obvious advantages in shortening mechanical ventilation, Intensive Care Unit (ICU) hospitalization time and reducing mortality, combined effects, the combined effect was not statistically significant ( P>0.05) . Conclusions:The standardized enteral nutrition process could effectively increase the calorie compliance rate of critical ill patients on the seventh day and reduce the incidence of feeding intolerance symptoms; however, it cannot significantly shorten the time of mechanical ventilation, ICU hospitalization time and reduce the mortality. Further research is needed for verification.

Ultraviolet light hardening therapy is an effective method for the treatment of polymorphic light eruption (PLE) . Recent studies have shown that narrow-band ultraviolet B (NB-UVB) is effective and safe for the prevention of recurrence of PLE. However, its treatment mechanisms still need further elucidation, and clinical studies with large sample size are needed for long-term tracking and assessment of initial dose of photohardening, dose-addition principle, treatment frequency and maintenance treatment protocols, in order to confirm the clinical application value of ultraviolet light photohardening therapy.

With the increasing life span of the population and the increasing proportion of the elderly population, the elderly with osteoporosis are prone to hip fractures, which brings heavy economic burdens to the family and society. The progress in predicting hip fractures from the aspects of the proximal femur geometry, bone mineral density (BMD), fracture risk assessment tool (FRAX) and finite element analysis (FEA) based on computed tomography (CT) imaging was reviewed, in order to understand the influencing factors of fracture risk, improve the accuracy of hip fracture risk prediction for the elderly, detect the high fracture risk group at an early stage, and hence to reduce the occurrence of fractures with appropriate preventing measures, and provide theoretical references for the prevention and treatment of hip fractures.
