Abstract
PURPOSE/OBJECTIVE(S) The phase III STELLAR (NCT02533271) trial demonstrated that four cycles of chemotherapy after short-course radiotherapy (SCRT-TNT) were not inferior to the standard care of long-course concurrent radiotherapy (LCRT) in patients with locally advanced rectal cancer (LARC). This study assessed the cost-effectiveness of SCRT-TNT versus LCRT in locally advanced rectal cancer in China on the basis of the STELLAR trial. MATERIALS/METHODS A Markov model was used to synthesize the healthcare costs and benefits of LARC patients based on results from the STELLAR trial. The model assumes that LARC who meet the inclusion criteria of the STELLAR trial experience four possible states: No Evidence of Disease (NED), locally recurrence, distant metastases, or any death from rectal cancer or other unrelated causes, where local recurrence continues to be classified as resectable and unresectable. The transition status period is 3 month, and 5 years is used to calculate direct medical costs and health benefits. The probabilities of states transition after SCRT-TNT or LCRT were derived from the results of the STELLAR trial and previous published article (Table.1). Costs were evaluated from the Chinese payer's perspective reported in early 2022 US dollars (US$1 = 6.78 Chinese Yuan). Sensitivity analyses were performed for key variables. Cost-effectiveness was evaluated using the incremental cost-effectiveness ratio and net monetary benefits. Effectiveness was defined as quality-adjusted life-years (QALYs). Willingness-to-pay (WTP) threshold was set at $43500/QALY. Data were collected from October 3, 2020, to September 20, 2021, and analyzed from November 15, 2020, to October 25, 2021. RESULTS During the 5-year horizon, for the base case scenario, SCRT-TNT incurred a lower total cost and higher QALYs compared with LCCRT. The total cost was $65767 and QALYs were 1.77 for SCRT-TNT; for LCCRT, the total cost was $72802 and QALYs were 1.64. This resulted in an ICER of -$ 55470.69 per QALY. Therefore, SCRT-TNT was a cost-saving and dominating treatment strategy compared with LCRT. Sensitivity analysis showed that ICERs were most sensitive to the parameters of distant metastases risk after treatment. CONCLUSION SCRT-TNT in locally advanced rectal cancer can be a cost-effective alternative to LCRT in China, and should be considered in appropriately selected patients.

Abstract
AIM To predict progesterone receptor (PR) expression of high-grade meningioma using radiomics based on enhanced T1-weighted imaging (WI). MATERIALS AND METHODS There were 157 cases of high-grade meningioma in the study. Seventy-eight cases had negative expression and 79 cases had positive expression. Spearman's rank correlation coefficient and least absolute shrinkage and selection operator (LASSO) regression were used to select the valuable features. The models were developed by naive Bayes (NB), random forest (RF), and support vector machine (SVM). Receiver operating characteristic (ROC) and decision curve analysis (DCA) analysis were used to assess the models. RESULTS Nine features were selected as the valuable features using Spearman's analysis and LASSO regression. The RF and NB models achieved the same area under the ROC curve (AUC) of 0.75, which was higher than that of SVM (0.74). There was no significant difference among the AUCs of the three models (p>0.05). There was a larger net benefit in the RF model than the SVM and NB models across all threshold probabilities in the DCA analysis. CONCLUSION The RF model had good performance in predicting PR expression of high-grade meningioma. PR expression evaluation for high-grade meningioma would be helpful in clinical practice.

Abstract
Objective: To investigate the status of knowledge, attitude, and behavior of enteral nutrition implemented by nurses in burn intensive care unit (BICU) and analyze its influencing factors. Methods: A multi-center cross-sectional survey research method was used. On May 8th, 2022, 107 BICU nurses who met the inclusion criteria were selected from the burn departments of the First Affiliated Hospital of Army Medical University (the Third Military Medical University), Guangdong Provincial People's Hospital, the First Affiliated Hospital of Guangxi Medical University, the Affiliated Hospital of Qinghai University, the Second Affiliated Hospital of Air Force Medical University, the Affiliated Hospital of Nantong University, Guiyang Steel Factory Staff Hospital, and the Second Affiliated Hospital of Kunming Medical University. The self-made nurses' enteral nutrition nursing knowledge-attitude-behavior questionnaire for severely burned patients was used to investigate the nurses' gender, age, working years, professional title, position, highest educational background, and whether they received systematic training in knowledge of enteral nutrition, the scores of each factor, and the total scores of knowledge, attitude, and behavior dimensions of enteral nutrition in nurses. The nurses were classified according to the general data, and the total scores of their knowledge, attitude, and behavior of enteral nutrition were calculated. Data were statistically analyzed with independent sample t test, one-way analysis of variance, Mann-Whitney U test, and Kruskal-Wallis H test. According to the results of univariate analysis and combined with clinical experience and significance, the generalized linear model analysis was carried out to screen the independent influencing factors of the total scores of knowledge, attitude, and behavior of enteral nutrition in BICU nurses. Results: A total of 107 nurses were surveyed, and 107 valid questionnaires were collected, with an effective recovery rate of 100%. In the BICU nurses' enteral nutrition knowledge-attitude-behavior questionnaire, the total scores of knowledge, attitude, and behavior were 44±13, 87±15, and 70±19, respectively. Most of the BICU nurses in this survey were female, aged 22-48 (31±6) years, and the number of nurses worked for 1-5, 6-10, and ≥11 years was evenly distributed. The majority of the professional titles of nurses were nurses, positions were responsible nurses, and the highest educational background was undergraduate. Forty-four nurses received systematic training in knowledge of enteral nutrition. There were statistically significant differences in the total scores of knowledge of enteral nutrition among BICU nurses with different ages, working years, professional titles, positions, highest educational background, and whether they received systematic training in knowledge of enteral nutrition (with H values of 27.36, 15.27, and 10.19, respectively, Z values of -3.33, -2.59, and -6.46, respectively, P<0.05). There were no statistically significant differences in the total scores of attitude and behavior of enteral nutrition among BICU nurses with different gender, ages, working years, professional titles, positions, highest educational background, and whether they received systematic training in knowledge of enteral nutrition (P>0.05). Age (26-30, 31-35, and ≥36 years old), highest educational background (undergraduate), and the systematic training received in enteral nutrition knowledge were the independent influencing factors for the total score of knowledge of enteral nutrition in BICU nurses (with 95% confidence intervals of 0.12-0.36, 0-0.30, 0.03-0.31, 0.01-0.32, and 0.19-0.40, respectively, standardized regression coefficients of 0.24, 0.15, 0.17, 0.17, and 0.29, respectively, P<0.05). There were no independent influencing factors for the total scores of enteral nutrition attitude and behavior of BICU nurses in different characteristics (P>0.05). Conclusions: The BICU nurses have low cognitive level in the implementation of enteral nutrition, their concept needs to be updated in time, and their behavior needs to be further standardized. Age (26-30, 31-35, and ≥36 years old), highest educational background (undergraduate), and the systematic training received in enteral nutrition knowledge were the independent influencing factors for the knowledge of enteral nutrition in BICU nurses.

Abstract
Objective: To explore the influence of social capital at work on anxiety of medical staff, and the mediating role of resilience. Methods: From March to May 2022, a total of 201 medical staff in the Affiliated Hospital of Jining Medical University were investigated with the General Information Questionnaire, Workplace Social Capital Scale, Connor-Davidson Resilience Scale (CD-RISC-10) and Generalized Anxiety Disorder-7 (GAD-7) . K-S method was used for normdity test of econometic voriobles, and normal distribution data were represented by Mean±SD, Pearson correlation analysis and linear regression analysis were used to test correlation between variables and mediating effect, and Bootstrap method was carried out by SPSS macro program PROCESS v3.5 to verify the mediating effect. Results: The detection rate of anxiety was 59.20% (119/201) in medical staff. The scores of social capital at work (28.90±5.83) and resilience (31.55±4.98) were negatively correlated with the score of anxiety (7.20±2.06) (r=-0.338, -0.510, P<0.001) , while the score of social capital at work was positively correlated with resilience (r=0.392, P<0.001) . Workplace social capital positively predicted resilience (β=0.392, P<0.001) , and both workplace social capital (β=-0.222, P=0.001) and resilience at work (β=-0.423, P<0.001) negatively predicted anxiety score. The direct effect of social capital in the workplace of medical staff on anxiety was -0.222 (95%CI: -0.349~-0.095, P=0.001) , and the indirect effect of resilience on anxiety was -0.166 (95%CI: -0.265~-0.080) . The resilience of medical staff had a partial mediating effect between workplace social capital and anxiety, which accounted for 42.78% of the total effect. Conclusion: The resilience of medical staff has a partial mediating effect between workplace social capital and anxiety. Workplace social capital can not only directly affect the anxiety of medical staff, but also indirectly affect it through resilience.

Abstract
Chest tightness variant asthma (CTVA) was first reported and named by Chinese scholars in 2013. It is a new clinical type of asthma characterized by chest tightness as the only or primary symptom, without typical asthma manifestations such as recurrent wheezing and shortness of breath, and without wheezing sounds heard during lung auscultation. The overall epidemiological data on CTVA is currently unavailable. Its pathogenesis is similar to that of typical asthma, involving eosinophilic airway inflammation. Due to the lack of typical clinical manifestations, insufficient knowledge of this disease in some clinicians and some other reasons, CTVA is susceptible to misdiagnosis or missed diagnosis. Currently, the diagnostic criteria for CTVA are: chest tightness as the only or primary symptom, without typical asthma symptoms and signs such as wheezing and shortness of breath, and with any one of the objective indicators of variable airflow limitation. Effective anti-asthma treatment is required, and other diseases that cause chest tightness, such as cardiovascular, digestive, nervous, muscular, and mental diseases should be excluded. CTVA treatment follows that of typical asthma, but the specific treatment duration is uncertain and may require long-term management. Traditional Chinese medicine has shown some therapeutic effects on CTVA. Most CTVA patients have a good prognosis after active anti-asthma treatment. This paper analyzes and summarizes the research of CTVA in China from 2013 and provides new perspectives for further exploration of CTVA.

Abstract
This article introduces the contents of the latest edition Risk of Bias in Non-randomized Studies-of Exposure (ROBINS-E) published in June 2022 [ROBINS-E (2022)], and gives some examples about its usage. ROBINS-E is a tool for assessing the risk of bias in non-randomized studies-of exposure. Compared with ROBINS-E (2019), ROBINS-E (2022) adds more bias for observational studies, covers a more comprehensive range of bias, and adds the assessment of the external authenticity of the study. ROBINS-E (2022) adds a preliminary evaluation process to improve the efficiency of evaluation. In addition, ROBINS-E (2022) visualizes and instrumentalizes the use of signal problems in the form of path graph, making it more convenient to use. ROBINS-E (2022), although more consideration has been given to the issue of co-exposure, still does not address the problem of effect modification in co-exposure, and there is still room to expand the applicable research.

Abstract
OBJECTIVE This study aimed to investigate the relationship between different dietary patterns and diabetic microvascular complications in patients with type 2 diabetes mellitus. PATIENTS AND METHODS This study was conducted based on the Chinese Chronic Disease and its Risk Factor Surveillance System. A multi-stage stratified sampling method was used to randomly select two districts (Henghualing District, Taiyuan City, and Yuzi District, Jinzhong City) and two counties (Huguan County, Changzhi City, and Jiang County, Yuncheng City) from the chronic disease surveillance sites in Shanxi Province to collect general information, dietary records, physical measurements, and laboratory tests. In total, 1,227 patients were enrolled according to the study criteria. Factor analysis was performed to construct six dietary patterns, and the relationship between dietary pattern scores and type 2 diabetic microvascular complications was analysed using binary logistic regression after correcting for confounders. RESULTS (1) Regarding the prevalence of type 2 diabetic microvascular complications and dietary characteristics, the prevalence of microvascular complications in patients with type 2 diabetes mellitus was 55.3% and was higher in urban than in rural areas. The prevalence of diabetic kidney disease (DKD), diabetic retinopathy, and diabetic peripheral neuropathy (DPN) were 21.4%, 12.7%, and 38.0%, respectively. (2) Six dietary patterns were constructed, namely, 'animal protein', 'coarse grains and plant protein', 'nuts and fruits', 'refined grains and vegetables', 'dairy', and 'added sugars', with factor contributions of 15.42%, 9.99%, 8.23%, 8.16%, 7.56%, and 7.28% respectively, explaining 56.64% of the total dietary variation. (3) After adjusting for confounding variables, the results of binary logistic regression indicated that patients in the highest quartile of dietary pattern scores for 'nuts and fruits' experienced a 43.3% lower risk of DKD compared to those in the lowest quartile [odds ratio (OR) = 0.567; 95% confidence interval (CI), 0.359-0.894; p < 0.001]. Similarly, patients in the highest quartile of dietary pattern scores for 'animal protein' had a 42.8% lower risk of DPN compared with those in the lowest quartile (OR = 0.572; 95% CI, 0.388-0.843; p < 0.05). CONCLUSIONS The results of this study suggest that in patients with type 2 diabetes mellitus, a 'nuts and fruits' dietary pattern reduces the risk of DKD and an 'animal protein' dietary pattern reduces the risk of DPN.

Abstract
Objective: To study the long-term clinical effect of transvaginal mesh (TVM) and pelvic floor reconstruction with native tissue repair (NTR) in the treatment of advanced pelvic organ prolapse (POP). Methods: Totally 207 patients with advanced POP who were treated in Hunan Provincial Maternal and Child Health Care Hospital from Jan. 2016 to Sep. 2019 were enrolled. The patient's pelvic organ prolapse quantification were all at degree Ⅲ or above, and they all complained for different degree of symptoms. They were divided into two groups according to the different surgical methods, TVM group and NTR group. In TVM group, the mesh was implanted through the vagina for pelvic floor reconstruction, while in NTR group, the traditional transvaginal hysterectomy combined with uterosacral ligament suspension and anterior and posterior wall repair, as well as perineal body repair were performed. The median follow-up time was 60 months, during the follow up time, 164 cases (79.2%, 164/207) had completed follow-up, including 76 cases in TVM group and 88 cases in NTR group. The perioperative data and complication rates of the two groups were compared, and the subjective and objective outcomes of the two groups at 1, 3 and 5 years were observed, respectively. The objective efficacy was evaluated by three composite criteria, namely: (1) the distance from the farthest end of the prolapse of the anterior and posterior wall of the vagina to the hymen is ≤0 cm, and the descending distance of the top is ≤1/2 of the total length of the vagina; (2) determine the disappearance of relevant POP symptoms according to "Do you often see or feel vaginal mass prolapse?"; (3) no further operation or pessary treatment was performed due to prolapse. If the above three criteria were met at the same time, the operation is successful; otherwise, it was recurrence. The subjective efficacy was evaluated by the pelvic floor distress inventory-short form 20 (PFDI-20) and pelvic floor impact questionnaire-short form 7 (PFIQ-7). Results: The median follow-up time of the two groups was 60 months (range: 41-82 months). Five years after the operation, the subjective and objective cure rates of TVM group were 89.5% (68/76) and 94.7% (72/76), respectively. The subjective and objective cure rates in NTR group were 80.7% (71/88) and 85.2% (75/88), respectively. There were significant differences in the subjective and objective cure rates between the two groups (χ2=9.869, P=0.002; χ2=3.969, P=0.046). The recurrence rate of TVM group was 5.3% (4/76), and that of NTR group was 14.8% (13/88). There was a significant difference between the two groups (P=0.046). The postoperative PFDI-20 and PFIQ-7 scores of the two groups were significantly lower than those before surgery, and there were significant differences of the two groups before and after surgery (all P<0.05). Postoperative mesh exposure in TVM group was 1.3% (1/76). Conclusions: The long-term outcomes between the two groups show that the subjective and objective outcomes of pelvic floor reconstruction in TVM group are significantly higher than those in NTR group, and the recurrence rate is significantly lower than that in NTR group. TVM has certain advantages in the treatment of advanced POP.

Abstract
Objective: To understand the infection status and epidemiological characteristics of hepatitis C in people aged 1-69 years in Henan Province in 2020. Methods: The estimated sample size was 5 827. From August to December 2020, multistage sampling was used to select 8 counties (districts) in Henan, and two survey sites were selected in each county (district), and a questionnaire survey was conducted in local people aged 1-69 years, blood samples were collected from them for anti-HCV, HCV RNA and genotype detections. Results: A total of 5 165 people aged 1-69 years completed the questionnaire survey. Men accounted for 44.76% (2 312/5 165), women accounted for 55.24% (2 853/5 165). In the people aged 1-69 years, the overall prevalence rates of anti-HCV and HCV RNA were 0.69% (95%CI: 0.68%-0.70%) and 0.20% (95%CI: 0.19%-0.21%) respectively. The prevalence rates of anti-HCV and HCV RNA were 0.48% (95%CI: 0.46%-0.50%), 0.09% (95%CI: 0.08%-0.10%) in men and 0.86% (95%CI: 0.85%-0.87%), 0.30% (95%CI: 0.28%-0.32%) in women. The prevalence rates of anti-HCV and HCV RNA increased with age. The prevalence rates of anti-HCV and HCV RNA were 0.87% (95%CI: 0.86%-0.88%), 0.28% (95%CI: 0.26%-0.30%) in urban residents and 0.53% (95%CI: 0.51%-0.55%), 0.14% (95%CI: 0.13%-0.15%) in rural residents. The genotyping results of 10 HCV RNA positive samples ware genotype 1b (4/10), genotype 2 (3/10), genotype 1b/3 (1/10), genotype 1b/3/6 (1/10) and genotype 2/6 (1/10). Conclusions: The prevalence of hepatitis C was low in Henan in 2020. It is necessary to strengthen hepatitis C surveillance in people aged 40 years and above. The major HCV genotypes were 1b and 2, and mixed genotype infection existed.

Abstract
Objective: To evaluate the effectiveness of a risk-adapted colorectal cancer screening strategy constructed utilizing genetic and environmental risk score (ERS). Methods: A polygenic risk score (PRS) was constructed based on 20 previously published single nucleotide polymorphisms for colorectal cancer in East Asian populations, using 2 160 samples with MassARRAY test results from a multicenter randomized controlled trial of colorectal cancer screening in China. The ERS was calculated using the Asia-Pacific Colorectal Screening Score system. Logistic regression was used to analyze the association between PRS alone and PRS combined with ERS and colorectal neoplasms risk, respectively. We also designed a risk-adapted screening strategy based on PRS and ERS (high-risk participants undergo a single colonoscopy, low-risk participants undergo an annual fecal immunochemical test, and those with positive results undergo further diagnostic colonoscopy) and compared its effectiveness with the all-acceptance colonoscopy strategy. Results: The high PRS group had a 26% increased risk of colorectal neoplasms compared with the low PRS group (OR=1.26, 95%CI: 1.03-1.54, P=0.026). Participants with the highest PRS and ERS were 3.03 times more likely to develop advanced colorectal neoplasms than those with the lowest score (95%CI: 1.87-4.90, P<0.001). As the risk-adapted screening simulation reached the third round, the detection rate of the PRS combined with ERS strategy was not statistically different from the all-acceptance colonoscopy strategy (8.79% vs. 10.46%, P=0.075) and had a higher positive predictive value (14.11% vs. 10.46%, P<0.001) and lower number of colonoscopies per advanced neoplasms detected (7.1 vs. 9.6, P<0.001). Conclusion: The risk-adapted screening strategy combining PRS and ERS helps achieve population risk stratification and better effectiveness than the traditional colonoscopy-based screening strategy.

Abstract
OBJECTIVE Chest computed tomography (CT) is increasingly being used to screen for lung cancer. Machine learning models could facilitate the distinction between benign and malignant pulmonary nodules. This study aimed to develop and validate a simple clinical prediction model to distinguish between benign and malignant lung nodules. PATIENTS AND METHODS Patients who underwent a video thoracic-assisted lobectomy between January 2013 and December 2020 at a Chinese hospital were enrolled in the study. The clinical characteristics of the patients were extracted from their medical records. Univariate and multivariate analyses were used to identify the risk factors for malignancy. A decision tree model with 10-fold cross-validation was constructed to predict the malignancy of the nodules. The sensitivity, specificity, and area under the curve (AUC) of a receiver operatic characteristics curve were used to evaluate the model's prediction accuracy in relation to the pathological gold standard. RESULTS Out of the 1,199 patients with pulmonary nodules enrolled in the study, 890 were pathologically confirmed to have malignant lesions. The multivariate analysis identified satellite lesions as an independent predictor for benign pulmonary nodules. Conversely, the lobulated sign, burr sign, density, vascular convergence sign, and pleural indentation sign were identified as independent predictors for malignant pulmonary nodules. The decision tree analysis identified the density of the lesion, the burr sign, the vascular convergence sign, and the drinking history as predictors of malignancy. The area under the curve of the decision tree model was 0.746 (95% CI 0.705-0.778), while the sensitivity and specificity were 0.762 and 0.799, respectively. CONCLUSIONS The decision tree model accurately characterized the pulmonary nodule and could be used to guide clinical decision-making.

Abstract
Objective: To explore the application effects of mind mapping combined with scenario simulation training on the ability training of junior nurses in hospital transfer of patients with critical burns and trauma. Methods: A prospective randomized controlled study was conducted. From December 2019 to December 2020, 55 female junior nurses from the Institute of Burn Research of the First Affiliated Hospital of Army Medical University (the Third Military Medical University) who met the inclusion criteria were enrolled in this study and divided into routine group (27 nurses, aged (24.0±0.9) years) and combined group (28 nurses, aged (24.2±0.8) years), according to the random number table. The nurses in routine group were trained with hospital transfer of patients with critical burns and trauma by theory combined with operational skill, and the nurses in combined group were trained with hospital transfer of patients with critical burns and trauma by mind mapping combined with scenario simulation training. Before and after the training, the self-made theoretical examination papers and skill assessment items were used for the examination and assessment to nurses, and their scores were calculated and compared. The self-made emergency ability scoring system was used to evaluate the emergency disposal ability of nurses from five dimensions, including team cooperation ability, emergency response ability, operative technique ability, specialized business ability, and nurse-patient communication ability, and their scores were calculated and compared. The non-standard implementation rates of transfer nursing measures, such as incomplete preparation of goods, poor communication effect of patients, inadequate pipeline nursing, unclear handover, and inadequate final treatment, were calculated and compared in the process of transporting highly simulated human (hereinafter referred to as simulated human) by nurses before and after training; and the rate of disease change and successful rate of transport of simulated human were calculated and compared after training. After assessment, self-made satisfaction questionnaire was used to compare nurses' satisfaction with the training mode, content, and effects. Data were statistically analyzed with independent sample t test, Pearson chi-square test, or Yates corrected chi-square test. Results: Fifty-five enrolled nurses were fully involved in the training, examination, assessment, and questionnaire filling. Before training, there were no statistically significant differences in theoretical examination and skill assessment scores between the 2 groups (P>0.05); After training, the theoretical examination and skill assessment scores of nurses in combined group were significantly higher than those in routine group (with t values of -3.89 and -4.24, respectively, P<0.05). Before training, there were no statistically significant differences in the scores of each item of emergency disposal ability between the 2 groups (P>0.05); after training, the scores in terms of team cooperation ability, emergency response ability, operative technique ability, specialized business ability, and nurse-patient communication ability of nurses in combined group were significantly higher than those in routine group (with t values of -6.49, -6.44, -2.21, -2.85, and -2.34, respectively, P<0.05). Before training, there were no statistically significant differences in the non-standard implementation rates of transfer nursing measures of nurses between the 2 groups (P>0.05); after training, the non-standard rates of incomplete preparation of goods, unclear handover, and inadequate final treatment of nurses in combined group were significantly lower than those in routine group (with t values of 3.87, 5.89, and 5.28, respectively, P<0.05). After training, the rate of disease change of simulated human of nurses in combined group was 7.14% (2/28), which was significantly lower than 33.33% (9/27) in routine group (χ2=5.89, P<0.05); the successful rate of transport was 96.43% (27/28), which was significantly higher than 74.07% (20/27) in routine group (χ2=3.87, P<0.05). After assessment, the total score of training satisfaction and scores of satisfaction with training mode and training effect of nurses in combined group were significantly higher than those in routine group (with t values of 5.22, 4.67, and 10.71, respectively, P<0.05). There was no statistically significant difference in the satisfaction score on training content between the two groups (P>0.05). Conclusions: Evidence-based mind mapping combined with scenario simulation training significantly improves the nursing skills and emergency handling capabilities of junior nurses in transferring patients with critical burns and trauma.

Abstract
Excessive sodium/salt intake is the leading dietary risk factor for the loss of healthy life in the Chinese population. The "Healthy China 2030" Action Plan set the goal of reducing salt intake by 20% by 2030. However, salt intake in China is still at a very high level in the world, with adults reaching 11 g/d, more than twice the recommended limit of 5 g/d. The current policies and action plans of China have targeted catering workers, children, adolescents, and home chefs in salt, oil, and sugar reduction actions. However, there are still obvious deficiencies in the coordinated promotion and implementation. This study, therefore, proposed a set of comprehensive strategies (named CHRPS that is composed of communication and education, salt reduction in home cooking, salt reduction in restaurants, reducing salt content in pre-packaged food, and surveillance and evaluation) and key implementation points for further deepening the salt reduction action in China. These strategies were developed based on the main sources of dietary sodium for Chinese residents, the status of"knowledge, attitude and practice"in salt reduction, evidence of effective intervention measures, existing policies and requirements, and the salt reduction strategies of the World Health Organization and experience from some other countries. As a scientific reference, the CHRPS strategies will help the government and relevant organizations quickly implement salt reduction work and facilitate the earlier realization of China's salt reduction goal.

Abstract
OBJECTIVE With the development and widespread use of fetal ultrasound and magnetic resonance technology in recent years, approximately 75% of fetuses are diagnosed prenatally with congenital structural malformations, a serious birth defect that endangers the life and health of the newborn. In this study, we aimed to study and analyze the value of the prenatal-postnatal integrated management model in the screening, diagnosis and treatment of fetal heart malformations. PATIENTS AND METHODS All pregnant women who were to undergo delivery in our hospital between January 2018 and December 2021 were recruited as the first subjects in this study, and after excluding those who refused to participate in the study, a total of 3,238 cases were finally included as subjects of this study. All pregnant women were screened for fetal heart malformations using the prenatal-postnatal integrated management model. Maternal files were established for all cases of heart malformations, grading the fetuses according to their heart disease grade, observing and recording their deliveries, treatment results and follow-ups. RESULTS After screening for heart malformations using the prenatal-postnatal integrated management model, 33 cases of heart malformations were identified, including 5 cases of Grade I (all delivered), 6 cases of Grade II (all delivered), 10 cases of Grade III (1 induced), and 12 cases of Grade IV (1 induced); 2 cases of ventricular septal defect healed spontaneously after delivery, and 18 infants were treated accordingly. The results of the later follow-up showed that 10 children had normalized their heart structure, 7 cases had slight alterations in the heart valves, and 1 case died. CONCLUSIONS The prenatal-postnatal integrated management model is a multidisciplinary cooperation model with certain clinical value in the screening, diagnosis and treatment of fetal heart malformations, which is beneficial to comprehensively improve the ability of hospital physicians in the grading management of heart malformations, detecting fetal heart malformations early and predicting fetal changes after birth. It further reduces the incidence of serious birth defects, conforms to the development trend of the diagnosis and treatment of congenital heart diseases, enables to reduce child mortality with timely treatment, effectively improves the surgical prognosis of critical and complex congenital heart diseases, with a promising application prospect.

Abstract
Objective: To investigate the clinical effects and related mechanism of antibiotic bone cement in treating diabetic foot ulcer (DFU). Methods: A prospective randomized controlled study was conducted. From August 2020 to August 2022, 24 patients with DFU who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University. According to the block randomization, the patients were divided into 2 groups, with 12 patients in each group. In antibiotic bone cement group, there were 7 male and 5 female patients, aged (64±8) years, with the ulcer area of (41±21) cm2. In silver sulfadiazine group, there were 8 male and 4 female patients, aged (62±8) years, with the ulcer area of (38±19) cm2. Under the condition of ensuring the patency of at least one main inferior genicular artery in each patient, the continuous vacuum sealing drainage was performed for 3-5 days after thorough debridement. Thereafter, the wounds in antibiotic bone cement group were treated with gentamicin-laden bone cement, and the wounds in silver sulfadiazine group were treated with silver sulfadiazine cream for dressing change. After 3 weeks of dressing change, the wound was covered with split-thickness skin graft from the lateral thigh on the affected side. Before debridement and after 3 weeks of dressing change, the blood flow intensities of wound tissue and normal skin tissue in foot were measured using laser Doppler flowmeter, and then, the percentage of relative blood flow intensity of wound and the change rate of blood flow intensity were calculated. After 3 weeks of dressing change, the wound margin tissue was taken, the number of CD31-positive neovascular and the vascular morphology were observed and detected by immunohistochemical staining, the morphology of blood vessels surrounded by CD31 and α-smooth muscle actin (α-SMA) double-positive cells was observed by immunofluorescence staining, the cell proliferation activity was evaluated by immunofluorescence staining (denoted as the ratio of Ki67 positive cells), and the protein expression of vascular endothelial growth factor receptor 2 (VEGFR2) was detected by Western blotting. The skin graft survival was observed 3-5 days after skin grafting, and the wound healing time was recorded. Data were statistically analyzed with independent sample t test and Fisher's exact probability test. Results: The percentages of relative blood flow intensity of wounds of patients before debridement were similar between the two groups (P>0.05). After 3 weeks of dressing change, the percentage of relative blood flow intensity of wounds and the change rate of blood flow intensity of patients in antibiotic bone cement group were (44.7±2.0)% and (129±12)%, respectively, which were significantly higher than (28.3±1.2)% and (41±8)% in silver sulfadiazine group (with t values of 24.15 and 20.97, respectively, P<0.05). After 3 weeks of dressing change, compared with those in silver sulfadiazine group, the number of CD31-positive neovascular in the wound margin tissue of patients in antibiotic bone cement group was significantly increased (t=33.81, P<0.05) with larger diameter and more regular arrangement, the vascular wall continuity surrounded by CD31 and α-SMA double-positive cells was better, and the ratio of Ki67 positive cells and protein expression of VEGFR2 were significantly increased (with t values of 40.97 and 47.38, respectively, P<0.05). On post skin grafting day 3-5, all the patients in antibiotic bone cement group and 8 patients in silver sulfadiazine group had good skin graft survival, while 4 patients in silver sulfadiazine group showed spotted/patchy skin graft necrosis, which were cured after corresponding treatment. The wound healing time of patients in antibiotic bone cement group was (47.1±2.9) d, which was significantly shorter than (58.8±2.3) d in silver sulfadiazine group (t=10.86, P<0.05). Conclusions: Compared with silver sulfadiazine, clinical application of antibiotic bone cement for treating DFU has the characteristics of accelerating wound healing and better reconstruction of local blood flow, which may be closely related to the fact that antibiotic bone cement promoted the local angiogenesis effectively in the wound through enhancing the expression of VEGFR2.

Abstract
Objective: To evaluate the initial safety and efficacy of femtosecond laser-assisted minimally invasive lamellar keratoplasty (FL-MILK) for advanced keratoconus. Methods: It was a case series study. Patients with advanced keratoconus who underwent FL-MILK between August 2017 and April 2020 at Shandong Eye Hospital were prospectively included. The femtosecond laser was used to create an intrastromal pocket in the recipient cornea and a lamellar cornea in the donor. The lamellar cornea was then gently inserted into the intrastromal pocket through the incision and flattened. Clinical measurements included best-corrected visual acuity, 3-mm anterior corneal mean keratometry, anterior and posterior central corneal elevation, central corneal thickness, corneal biomechanics, and endothelial cell density. The follow-up was conducted at 1 month, 12 months, and 24 months after the operation. Results: There were 33 patients (35 eyes) in the study. Twenty-six patients were male and 7 patients were female. The mean age was (20.34±5.24) years old. All patients completed 12 months of follow-up, and 25 patients (27 eyes) completed 24 months of follow-up. No epithelial ingrowth, infection, or allogeneic rejection was observed. Compared with the preoperative data, the anterior central corneal elevation significantly decreased (P<0.001), the mean keratometry significantly decreased (P<0.05), and the central corneal thickness significantly increased (P<0.001). The corneal biomechanical strength was significantly improved, with the deformation amplitude ratio at 2.0 mm decreasing from 1.39±0.14 preoperatively to 1.21±0.10 at 24 months postoperatively (P<0.001) and the stiffness parameter at the first applanation increasing from 41.49±11.47 preoperatively to 88.41±18.17 at 24 months postoperatively (P<0.001). There were no significant changes in the mean best-corrected visual acuity, posterior corneal elevation, mean spherical equivalent, and endothelial cell density (all P>0.05). Conclusions: FL-MILK may be a feasible option for advanced keratoconus. This procedure may provide a new resolution for keratoconus.

Abstract
Objective: To investigate the association between screen exposure and language skills in children aged 2-5 years. Methods: There were 299 children aged 2-5 years, recruited by convenience sampling from those who visited the Center of Children's Healthcare, Children's Hospital, Capital Institute of Pediatrics for routine physical examination from November 2020 to November 2021. Their development status were evaluated by the children neuropsychological and behavioral scale (revision 2016). A self-designed questionnaire for parents was conducted to collect demographic and socioeconomic information and screen exposure characteristics (time and quality). One-way ANOVA and independent sample t test were applied to compare the differences in language development quotient of children with different screen exposure time and quality. Multiple linear regression was used to analyze the correlation between screen exposure time and quality with language developmental quotient. Multivariate Logistic regression was used to analyze the risk of language underdevelopment in children with different screen exposure time and quality. Results: Among 299 children, 184 (61.5%) were boys and 115 (38.5%) were girls, with the age of (3.9±1.1) years. The number of children with daily screen time <60, 60-120 and>120 min was 163 children (54.5%), 86 children (28.8%) and 50 children (16.7%), respectively, with the language development quotients of 94±13, 90±13, 84±14, respectively, demonstrating a statistically significant difference (F=8.92, P<0.001). Logistic regression analysis revealed that screen exposure time of 60-120 and >120 min per day were both risk factors for children's language developmental quotients (OR=2.28, 95%CI 1.00-5.17, P=0.043; OR=3.96, 95%CI 1.86-9.17, P<0.001), and co-viewing and exposure to educational programs were both protective factors for children's language developmental quotients (OR=0.48, 95%CI 0.25-0.91, P=0.024, OR=0.36, 95%CI 0.19-0.70, P=0.003). Conclusions: Excessive exposure screen time and inappropriate screen exposure habits are associated with children's poorer language development. Screen exposure time should be limited and screen use should be rational to promote children's language skills.

Abstract
1. As RIPK2 (receptor interacting serine/threonine kinase 2) has been shown to to alleviate excessive inflammatory responses, the following study conducted a systematic and in-depth analysis of the mRNA-seq and miRNA-seq data from chicken macrophages with/without over-expression of RIPK2 (oeRIPK2) combined with/without avian pathogenic E. coli (APEC) infection to identify the miRNA-mRNA interaction network and potential signalling pathways involved.2. A total of 9,201 differentially expressed (DE) mRNAs and 300 DE miRNA were identified in both oeRIPK2+APEC vs. APEC and oeRIPK2 vs. the wild-type (WT). Moreover, 4,269 instances of co-expression between miRNAs and mRNAs were seen involving 1,652 DE mRNAs and 164 DE miRNAs.3. Functional analysis of the DE mRNAs in the miRNA-mRNA interaction network showed that 223 biological processes and five KEGG pathways were significantly enriched in the two comparisons. In total, 128 pairs of miRNA-mRNA interactions were involved in the identified MAPK signalling pathway and focal adhesion immune related pathways.4. Significantly, these screened miRNAs (gga-miR-222b-5p and gga-miR-214) and their target genes were highly correlated with APEC infection and RIPK2. These recognised key genes, miRNA and the overall miRNA-mRNA regulatory network, enables better understanding of the molecular mechanism of host response to APEC infection, especially related to RIPK2.

Venous thromboembolism (VTE) has become a serious medical problem faced by medical personnel all over the world, due to its high incidence, high fatality, and easily missed and misdiagnosed. Patients with severe burns are at high risk for VTE due to the presence of blood hypercoagulability, central venous catheterization, repeatedly received surgical procedures, and prolonged bed rest. Identifying the risk factors of VTE in burn patients and taking targeted preventive measures are the key to reduce the incidence of VTE. However, there are no risk assessment tools or prevention guidelines for VTE in burn patients at home and abroad, and scholars from various countries are actively exploring the occurrence, influencing factors, and prevention of VTE in burn patients. This paper reviews the research progress of the occurrence situation, related risk factors, risk assessment, and prevention of VTE in burn patients in recent years, and discusses the existing problems and future research directions in this field.

Abstract
Non-syndromic oral cleft (NSOC), a common birth defect, remains to be a critical public health problem in China. In the context of adjustment of childbearing policy for two times in China and the increase of pregnancy at older childbearing age, NSOC risk prediction will provide evidence for high-risk population identification and prenatal counseling. Genome-wide association study and second generation sequencing have identified multiple loci associated with NSOC, facilitating the development of genetic risk prediction of NSOC. Despite the marked progress, risk prediction models of NSOC still faces multiple challenges. This paper summarizes the recent progress in research of NSOC risk prediction models based on the results of extensive literature retrieval to provide some insights for the model development regarding research design, variable selection, model-build strategy and evaluation methods.
