AIM: To evaluate the pathogenic variants of the SCO2(OMIM 604272)gene in patients with high myopia from Enshi Tujia and Miao Autonomous Prefecture of China.METHODS: A total of 384 patients with high myopia whose spherical refractive error was ≤ -6.00 D and whose axial length was ≥26.00 mm in at least one eye were recruited. DNA was extracted by the phenol-chloroform method from 5 mL of peripheral venous blood. Sanger sequencing was performed to identify pathogenic variants in exon 2 of SCO2. The detected variants were evaluated via in silico prediction software. A total of 288 people from the same district were included as the normal control cohort.RESULTS: Seven variants were detected, namely, four synonymous variants(c.201C>T/p.=, c.576C>T/p.=, c.633A>C/p.=, c.780T>C/p.=.), two missense variants(c.187A>G/p.Ile63Val, c.59G>C/p.Arg20Pro)and one nonsense variant(c.544C>T/p.Gln182*). The two missense variants were not damaging, as predicted by PolyPhen2, SIFT and Provean. The novel nonsense variant(c.544C>T/p.Gln182*)cannot be found in the 1000 Genomes Project and was not identified in 288 normal controls. Variant Taster suggested that the nonsense variant site was conserved.CONCLUSION: The newly identified nonsense mutation may be responsible for high myopia of the patients in our cohort. SCO2 is associated with high myopia, while the incidence of SCO2 variants in high myopia in this cohort was as low as 1/384; the nonsense mutation may be a scarce variant of high myopia in the Enshi Tujia and Miao Autonomous Prefecture of China.

Objective:To analyze the prognostic value and threshold effect of serum C3,C4 in patients with multiple myeloma (MM). Methods:The clinical data of 146 patients with MM who visited Suqian First People's Hospital from October 2016 to October 2019 were collected. The patients were divided into deceased group (42 cases) and survival group (104 cases) according to their prognosis and survival. The risk factors affecting the prognosis of the patients were analyzed. The correlation of serum C3 and C4 with prognosis was analyzed by threshold effect. The predictive value of serum C3/C4 on the prognosis of MM patients was evaluated by the receiver operating characteristic (ROC) curve. Nomogram model was constructed,and the discrimination and accuracy of the model were evaluated. The nomogram model was internally validated by bootstrap resampling. Results:Durie-Salmon (DS) stage Ⅲ,decreased low density lipoprotein cholesterol (LDL-C) and apolipoprotein B (Apo B),elevated homocysteine (Hcy),uric acid (UA),and serum C3 and C4 were independent risk factors affecting the prognosis of MM patients (P<0.05). Curve fitting showed that the mortality probability of MM patients increased with the increase of serum C3 and C4 levels. The threshold effect analysis showed that when serum C3 was higher than 1.2 g/L or serum C4 was higher than 0.37 g/L,the mortality rate of MM patients increased with the increase of the index levels;When serum C3 was lower than 1.2 g/L or serum C4 was lower than 0.37 g/L,the mortality rate of MM patients had no significant correlation with the indexes. Serum C3 and C4 had a good predictive value for the prognosis of MM patients,and the combination of C3 and C4 had a higher predictive value. The validation results showed that the nomogram model constructed in our study had good discrimination and high accuracy. Conclusion:Elevated levels of serum C3 and C4 are independent risk factors for mortality in patients with MM. The combination of serum C3 and C4 is more valuable in predicting mortality in MM patients than C3 or C4 alone,which can be used as a sensitive index to evaluate the prognosis of MM patients.

The theory of "liver opens at the eyes" was first seen in Yellow Emperor's Internal Canon of Medicine， which is the ancient people's summary of the connection between the liver and the eyes. The theory of "liver opens at the eyes" suggests the characteristic of "co-damage and co-recover of liver and eyes". It has been found in clinical practice that liver diseases and eye diseases often occur together， and "liver and eyes co-recover" is an ideal choice. The key to achieving "liver and eyes co-recover" is to analyze its pharmacological material basis and mechanism. With the development of modern medicine， more and more evidence indicates that the liver and eyes have complex and close relationships in physiological and pathological aspects. In a pathological state， there is a phenomenon of "liver and eyes co-damage"， and after the intervention of traditional Chinese medicine， "liver and eyes co-recover" occurs. "Liver and eyes co-damage and co-recover" can be explained through the "co-material basis and co-action mechanism". On this basis， the research group tentatively proposed that the liver and eyes had "four common characteristics" （4CCs）， namely "co-damage， co-recover， co-material basis， and co-action mechanism" from the theoretical connotation of traditional Chinese medicine， clinical practice， and molecular biology. Additionally， the group also took the intervention of Prunella vulgaris， traditional Chinese medicine， for removing liver fire and improving eyesight on immune liver injury （ILI） and allergic conjunctivitis （AC） as examples to analyze 4CCs. This project aims to deeply analyze the scientific connotation of the theory of "liver opens at the eyes"， reveal the common characteristics and biological essence of liver and eyes， explore a new research paradigm of "liver and eyes co-recover"， and provide a reference for the study of common problems of multi-organ associated diseases.

Objective:To explore the relationships among perceived social constraints, social participation, as well as anxiety and depression in first stroke patients, and to further analyze the mediating effect of social participation on these variables.Methods:A total of 216 first stroke patients in the Department of Neurology of Affiliated Hospital of Qingdao University from April to December 2020 were recruited by convenience sampling and investigated by general information questionnaire, Social Constraints Scale (SCS), Chinese version of Impact on Participation and Autonomy Questionaire (IPA-C) and Hospital Anxiety and Depression Scale (HADS).Results:The total score of SCS, IPA-C, depression and anxiety were 33.49 ± 6.81, 43.42 ± 9.62, 8.05 ± 4.15 and 8.61 ± 2.59. Social constraints were positively correlated with social participation as well as anxiety ( r=0.644, 0.383, both P<0.05). Social constraints were positively correlated with social participation as well as depression ( r=0.482, 0.371, both P<0.05). The quality of social participation partially mediated the relationship between social constraints and anxiety (intermediary effect was 0.119), and also partially mediated the relationship between social constraints and depression (intermediary effect was 0.270). Conclusions:First stroke patients experience high level of social constraints, low quality of social participation and severe anxiety and depression. Social constraints can affect anxiety and depression through social participation. Medical staff should build a good environment to meet the needs of stroke patients of social participation, help patients to establish a correct psychological coping style, reduce patients' avoidance of social participation due to perceived constraints and exclusion, and thus promote the mental health of patients.

【Objective】 To explore the correlation between serum trace elements and systolic and diastolic blood pressure in healthy population and patients with hypertension. 【Methods】 The health examination data of the subjects from our hospital from September 2018 to May 2021 were selected. They consisted of 3430 healthy people with no history of chronic diseases and 216 patients with hypertension previously diagnosed. We measured the levels of serum zinc， iron， calcium， magnesium， lead， copper and cadmium and analyzed their correlation with systolic blood pressure （SBP） and diastolic blood pressure （DBP）. 【Results】 The incidence of low zinc （9.5%） and hypomagnesemia （1.8%） was relatively low， while hypomagnesemia （27.8%） was relatively common in the healthy population. Logistic regression analysis showed that age， BMI and serum albumin were associated with increased SBP and DBP. Fasting blood glucose （OR=1.095， 95% CI： 1.007-1.191） and blood lead （OR=1.006， 95% CI： 1.000-1.012） were risk factors for SBP. Serum total cholesterol （OR=1.244， 95% CI： 1.095-1.412）， serum iron （OR=1.275， 95% CI： 1.114-1.460） and blood lead （OR=1.010， 95% CI： 1.004-1.015） were risk factors， while serum magnesium （OR=0.488， 95% CI： 0.266-0.894） acted as a protective factor for DBP. After adjusting for age， gender， BMI， waist-hip ratio， and smoking history， there was no significant difference in serum trace element levels between the hypertension and healthy control groups. 【Conclusion】 SBP is correlated with serum lead， while DBP is positively correlated with serum iron and lead， but negatively correlated with serum magnesium in normal healthy population. There was no significant difference in serum trace element content between hypertensive patients and healthy control group， but the conclusion still needs to be further verified.

BACKGROUND: Glucose control is an important aspect in managing critically ill patients. The goal of this study was to compare the effects of sequential feeding (SF) and continuous feeding (CF) on the blood glucose of critically ill patients. METHODS: A non-inferiority randomized controlled trial was adopted in this study. A total of 62 patients who were fed enteral nutritional suspension through gastric tubes were enrolled. After achieving 80% of the nutrition target calories (25 kcal·kg-1·day-1) through CF, the patients were then randomly assigned into SF and CF groups. In the SF group, the feeding/fasting time was reasonably determined according to the circadian rhythm of the human body as laid out in traditional Chinese medicine theory. The total daily dosage of the enteral nutritional suspension was equally distributed among three time periods of 7 to 9 o'clock, 11 to 13 o'clock, and 17 to 19 o'clock. The enteral nutritional suspension in each time period was pumped at a uniform rate within 2 h by an enteral feeding pump. In the CF group, patients received CF at a constant velocity by an enteral feeding pump throughout the study. Blood glucose values at five points (6:00/11:00/15:00/21:00/1:00) were monitored and recorded for seven consecutive days after randomization. Enteral feeding intolerance was also recorded. Non-inferiority testing was adopted in this study, the chi-square test or Fisher test was used for qualitative data, and the Mann-Whitney U test was used for quantitative data to determine differences between groups. In particular, a repeated measure one-way analysis of variance was used to identify whether changes in glucose value variables across the time points were different between the two groups. RESULTS: There were no significant demographic or physiological differences between the SF and CF groups (P > 0.050). The average glucose level in SF was not higher than that in CF (8.8 [7.3-10.3] vs. 10.7 [9.1-12.1] mmol/L, Z = -2.079, P for non-inferiority = 0.019). Hyperglycemia incidence of each patient was more common in the CF group than that in the SF group (38.4 [19.1-63.7]% vs. 11.8 [3.0-36.7]%, Z = -2.213, P = 0.027). Hypoglycemia was not found in either group. Moreover, there was no significant difference during the 7 days in the incidence of feeding intolerance (P > 0.050). CONCLUSIONS: In this non-inferiority study, the average blood glucose in SF was not inferior to that in CF. The feeding intolerance in SF was similar to that in CF. SF may be as safe as CF for critically ill patients. TRIAL REGISTRATION ClinicalTrials.gov, NCT03439618; https://clinicaltrials.gov/ct2/show/record/NCT03439618.

Objective: To examine the integrated model of self-management behavior in middle-aged stroke patients based on health belief model and planned behavior theory. Methods: A self-designed general information questionnaire, self-management behavior cognition and attitude questionnaire and self-management behavior scale, were used to investigate 654 cases of first middle-aged stroke patients in the neurology department of 3 grade a hospitals in Qingdao. Results: The standardization factor load of each theoretical dimension in the theoretical integration model was 0.51-0.91 (0.72±0.11). Behavioral intention had a direct positive predictive effect on self-management behavior, with an effect value of 0.49 (t = 7.41, P < 0.01). Perceived behavior control not only had a direct positive prediction effect on self-management behavior, but also indirectly influenced self-management behavior through behavioral intention. The effect values are 0.12 (t = 2.75, P < 0.05) and 0.04 (t = 2.18, P < 0.05), respectively. Behavioral attitude exerts influence on self-management behavior through behavioral intention, and the effect value is 0.40 (t = 14.71, P < 0.01). Subjective norms not only influenced self-management behavior through behavioral intention, but also indirectly influenced behavioral intention and self-management behavior through behavioral attitude, with the effect value of 0.25. The effects of perceived benefits and perceived severity on self-management behaviors were 0.21 and 0.04, respectively. The theoretical integration model can explain 62% variance variation of self-management behavior. Conclusion The theoretical integration model of self-management behavior of middle-aged stroke patients based on the health belief model and planned behavior theory can better explain the behavior. This model can be applied to stroke patients in an attempt to provide theoretical basis for the formulation of personalized nursing measures for stroke patients.

Objective: To investigate the efficacy of massage combined with microwave therapy in treating Children's bronchial pneumonia with syndrome of deficiency of lung-spleen Qi. Methods: Two hundred forty-four bronchial pneumonia Children were selected in our hospital and randomly divided into the control group and the observation group with 122 cases in each group referring to random number table. The control group was administered with the routine treatment. Based on the control group, the observation group received the massage and microwave therapy. The course was 2 week for both groups. The syndrome scores of traditional Chinese medicine were performed before and after treatment, and the disappearance of gasping, antipyretic, disappearance of moist rale in the lungs, and absorption time of chest X-ray were observed and recorded. the flow cytometry was used to detect peripheral blood levels of CD4⁺ and CD8⁺, and serum levels of IL-6 and IL-8 were detected by ELISA. The clinical effect rate was evaluated. Results: The total effective rate was 97.5% (118/121) in the observation group and 91.7% (110/120) in the control group,with statistically significant differences (χ²=4.406, P=0.044). After treatment, the scores of cough, phlegm, shortness of breath, pale face, fatigue, spontaneous perspiration, poor appetite in the observation group were significantly lower than those in the control group (t value were 10.008, 11.529, 11.778, 12.043, 11.309, 10.128, 11.008, P<0.01), and elapsed time of gasping, antifebrile time, disappear time of lung moist crackles, absorption time were significantly earlier than the control group (t value were 15.121, 10.099, 18.441, 14.310, P<0.01). After 2 week’ treatment, the scores of symptoms of deficiency of lung-spleen Qi in the observation group were significantly lower than those of control group (P<0.01). Compared with the control group, the duration of wheezing and antipyretic, duration of lung dampness and chest X-ray absorption in the observation group were significantly decreased (P<0.05). The total effective rate of the observation group was 97.52%, which was significantly higher than the control group 92.67% (P<0.05). After 2 week treatment, the CD4⁺ (41.03% ± 4.55% vs. 33.52% ± 3.95%, t=14.011) in the observation group was significantly higher, CD8⁺ (22.71% ± 2.83% vs. 26.65% ± 3.05%, t=10.061) was significantly lower than the control group, serum levels of IL-6 (28.13 ± 3.63 ng/L vs. 40.09 ± 4.61 ng/L, t=14.890) and IL-8 (21.41 ± 2.75 ng/L vs. 29.05 ± 3.61 ng/L, t=11.439) were significantly lower than the control group (P<0.01). Conclusions Massage combined with microwave therapy for the Children's bronchial pneumonia with deficiency of lung-spleen Qi syndrome can promote the improvement of symptoms, enhance the efficacy, increase the immune function and reduce inflammation level.

As an important means of lung protective strategy, prone position ventilation (PPV) which can effectively shorten the time of mechanical ventilation, significantly reduce the mortality of patients with acute respiratory distress syndrome (ARDS), and is suitable for popularization and application in the ICU. However, some studies show that prolonged prone position can significantly increase the incidence of Stress injury, making it difficult to implement PPV in the practical level. In order to achieve the goal of safe and effective prevention of skin Stress injury, and to promote the correct implementation of PPV, this paper review the methods of preventing Stress injury in patients with PPV.

Objective To investigate the clinical therapeutic methods and their curative effects in recurrent ischemic angina for internal mammary artery resterosis after coronary artery bypass grafting (CABG).Methods We enrolled the patients who had recurrence of ischemic angina for restenosis of internal mammary artery graft after CABG as research subjects in the Affiliated Hospital of Yan'an University from January 2014 to January 2016.The 42 patients were divided into three groups according to the different treatment approaches for recurrence of ischemic angina:Group A (n=22)who received internal mammary artery interventional therapy;Group B (n=12)who received coronary artery bypass grafting treatment;and Group C (n=8)who received left subclavian artery proximal stent treatment.Then we compared the clinical therapeutic effects in the three groups.Results The success rate in Group C was 100%,which was the highest in the three groups,and the post-operative restenosis rate was 0.The hospitalization time was significantly shorter in Group A than in Group B (P＜0.05).However,the two groups did not significantly differ in mortality,success rate or restenosis rate (P＞0.05).Conclusion We should select the appropriate treatment according to the patient's specific situation for recurrent ischemic angina. Endovascular treatment has evident therapeutic effects,rapid postoperative recovery,and lower treatment risk, making it the preferred treatment when possible.
