Objective To explore the process and main behavior characteristics of behavioral characteristics of patients with recurrent hypoglycemia in the degeneracy of blood glucose management.Methods A mixed-method convergent design was used to collect data.From June 2022 to April 2023,382 patients with recurrent hypoglycemia were admitted to the endocrine department of a tertiary hospital in Jiangsu were recruited to score of ego depletion.K-means clustering was conducted to analyze the distribution characteristics of patients'characteristics in blood glucose management.At the same time,19 patients who were selected from the participants of the quantitative study were recruited to attend semi-structured interviews.Results Quantitative results analysis:the average score of blood glucose management loss was(49.20±6.58),and the average scores of cognitive control,behavioral control and emotional control were(17.90±4.12),(15.49±3.64)and(15.81±3.58),respectively.The results of cluster analysis showed that behavioral characteristics could be divided into 3 groups:a cognitive depletion group,an emotional depletion group and a self-control group.Qualitative data analysis:the process of deterioration of management in patients included 3 major themes,including the antecedents of ego depletion,the process of ego depletion and the aftereffects of ego depletion.Analysis of the mixed results showed that the status of ego depletion is serious;patients ignore the behavioral elements of active participation in blood glucose management,show many irrational decision-making behaviors,and the degradation behavior characteristics of patients'blood glucose management are different.Conclusion The degeneration behavior of blood glucose management was serious and affected by single or multiple factors,continuously consuming self-control energy and causing ego depletion.To promote the long-term maintenance of blood glucose management,priority should be given to take actions to enhance patients'perceptions,emotion and behaviors,help them learn about the possible blood glucose changes,improve their understanding and recognition of the value of scientific management.

【Objective】 To establish an effective quality indicator monitoring system, scientifically and objectively evaluate the quality management level of blood banks, and achieve continuous improvement of quality management in blood bank. 【Methods】 A quality monitoring indicator system that covers the whole process of blood collection and supply was established, the questionnaire of Quality Monitoring Indicators for Blood Collection and Supply Process with clear definition of indicators and calculation formulas was distributed to 17 blood banks in Shandong. Statistical analysis of 21 quality monitoring indicators in terms of blood donation service (10 indicators), blood component preparation (7 indicators ), and blood supply (4 indicators) from each blood bank from January to December 2022 were conducted using SPSS25.0 software The differences in quality monitoring indicators of blood banks of different scales were analyzed. 【Results】 The average values of quality monitoring indicators for blood donation service process of 17 blood banks were as follows: 44.66% (2 233/5 000) of regular donors proportion, 0.22% (11/50) of adverse reactions incidence, 0.46% (23/5 000) of non-standard whole blood collection rate, 0.052% (13/25 000) of missed HBsAg screening rate, 99.42% (4 971/5 000) of first, puncture successful rate, 86.49% (173/200) of double platelet collection rate, 66.50% (133/200) of 400 mL whole blood collection rate, 99.25% (397/400) of donor satisfaction rate, 82.68% (2 067/2 500) of use rate of whole blood collection bags with bypass system with sample tube, and 1 case of occupational exposure in blood collection.There was a strong positive correlation between the proportion of regular blood donors and the collection rate of 400 mL whole blood (P<0.05). The platelet collection rate, incidence of adverse reactions to blood donation, and non-standard whole blood collection rate in large blood banks were significantly lower than those in medium and small blood banks (P<0.05). The average quality monitoring indicators for blood component preparation process of 17 blood banks were as follows: the leakage rate of blood component preparation bags was 0.03% (3/10 000), the discarding rate of lipemic blood was 3.05% (61/2 000), the discarding rate of hemolysis blood was 0.13%(13/10 000). 0.06 case had labeling errors, 8 bags had blood catheter leaks, 2.76 bags had blood puncture/connection leaks, and 0.59 cases had non-conforming consumables. The discarding rate of hemolysis blood of large blood banks was significantly lower than that of medium and small blood banks (P<0.05), and the discarding rate of lipemic blood of large and medium blood banks was significantly lower than that of small blood banks (P<0.05). The average values of quality monitoring indicators for blood supply process of 17 blood banks were as follows: the discarding rate of expired blood was 0.023% (23/100 000), the leakage rate during storage and distribution was of 0.009%(9/100 000), the discarding rate of returned blood was 0.106% (53/50 000), the service satisfaction of hospitals was 99.16% (2 479/2 500). The leakage rate of blood components during storage and distribution was statistically different with that of blood component preparation bags between different blood banks (P<0.05). There were statistically significant differences in the proportion of regular blood donors, incidence of adverse reactions, non-standard whole blood collection rate, 400 mL whole blood collection rate, double platelet collection rate, the blood bag leakage rate during preparation process, the blood components leakage rate during storage and distribution as well as the discarding rate of lipemic blood, hemolysis blood, expired blood and returned blood among large, medium and small blood banks (all P<0.05). 【Conclusion】 The establishment of a quality monitoring indicator system for blood donation services, blood component preparation and blood supply processes in Shandong has good applicability, feasibility and effectiveness. It can objectively evaluate the quality management level, facilitate the continuous improvement of the quality management system, promote the homogenization of blood management in the province and lay the foundation for future comprehensive evaluation of blood banks.

Cockayne syndrome(CS)group B(CSB),which results from mutations in the excision repair cross-complementation group 6(ERCC6)genes,which produce CSB protein,is an autosomal recessive disease characterized by multiple progressive disorders including growth failure,microcephaly,skin photosensitivity,and premature aging.Clinical data show that brain atrophy,demyelination,and calcification are the main neurological manifestations of CS,which progress with time.Neuronal loss and calcification occur in various brain areas,particularly the cerebellum and basal ganglia,resulting in dyskinesia,ataxia,and limb tremors in CSB patients.However,the understanding of neurodevelopmental defects in CS has been constrained by the lack of significant neurodevelopmental and functional abnormalities observed in CSB-deficient mice.In this review,we focus on elucidating the protein structure and distribution of CSB and delve into the impact of CSB mutations on the development and function of the nervous system.In addition,we provide an overview of research models that have been instrumental in exploring CS disorders,with a forward-looking perspective on the substantial contributions that brain organoids are poised to further advance this field.

Objective    To compare the surgical efficacy of Da Vinci robot-assisted minimally invasive esophagectomy (RAMIE) and video-assisted minimally invasive esophagectomy (VAMIE) on esophageal cancer. Methods    Online databases including PubMed, the Cochrane Library, Medline, EMbase and CNKI from inception to 31, December 2019 were searched by two researchers independently to collect the literature comparing the clinical efficacy of RAMIE and VAMIE on esophageal cancer. Newcastle-Ottawa Scale was used to assess quality of the literature. The meta-analysis was performed by RevMan 5.3. Results    A total of 14 studies with 1 160 patients were enrolled in the final study, and 12 studies were of high quality. RAMIE did not significantly prolong total operative time (P=0.20). No statistical difference was observed in the thoracic surgical time through the McKeown surgical approach (MD=3.35, 95%CI –3.93 to 10.62, P=0.37) or in surgical blood loss between RAMIE and VAMIE (MD=–9.48, 95%CI –27.91 to 8.95, P=0.31). While the RAMIE could dissect more lymph nodes in total and more lymph nodes along the left recurrent laryngeal recurrent nerve (MD=2.24, 95%CI 1.09 to 3.39, P=0.000 1; MD=0.89, 95%CI 0.13 to 1.65, P=0.02) and had a lower incidence of vocal cord paralysis (RR=0.70, 95%CI 0.53 to 0.92, P=0.009). Conclusion    There is no statistical difference observed between RAMIE and VAMIE in surgical time and blood loss. RAMIE can harvest more lymph nodes than VAMIE, especially left laryngeal nerve lymph nodes. RAMIE shows a better performance in reducing the left laryngeal nerve injury and a lower rate of vocal cord paralysis compared with VAMIE.

The incidence of rib fracture in patients with chest trauma is about 70%. Simple rib fractures do not need special treatment. Multiple rib fractures and flail chest are critical cases of blunt trauma, which often cause serious clinical consequences and need to be treated cautiously. Nowadays, there is a controversy about the diagnosis and treatment of multiple rib fractures and flail chest. In the past, most of the patients were treated by non-operative treatment, and only less than 1% of the patients with flail chest underwent surgery. In recent years, studies have confirmed that surgical reduction and internal fixation can shorten the hospital stay, and reduce pain and cost for patients with flail chest, but there is still a lack of relevant clinical consensus and guidelines for diagnosis and treatment, which leads to great differences in clinical diagnosis and treatment plans. This article reviewed the treatment, surgical indications and surgical timing of multiple rib fractures and flail chest.

Objective:To analyze the trend of premature death of non-communicable diseases (NCDs) in Wuxi from 2008 to 2018 and evaluate the influence of premature mortality probability caused by four main NCDs on life expectancy.Methods:Based on the mortality data collected by Wuxi Mortality Registration System and the population data collected by Wuxi Public Security Bureau during 2008-2018, this study analyzes the trend of the probability of premature death on malignant tumors, cardiovascular and cerebrovascular diseases, chronic respiratory diseases, and diabetes. The impact on life expectancy was analyzed by using the methods of abridged life table, Joinpoint regression, and life expectancy contribution decomposition.Results:From 2008 to 2018, the total probability of premature death of four main NCDs in Wuxi were declined consistently from 11.25% to 9.25% (AAPC = -2.0%, 95% CI: -2.6--1.5), higher in female (from 7.74% to 5.91%) than that in male (from 14.49% to 12.51%). The Wuxi resident's life expectancy increased by 1.86 years (from 78.66 to 80.52 years), in males and 1.26 years (from 83.85 to 85.11 years) in females, respectively. The decline of premature death of malignant tumors, cardiovascular and cerebrovascular diseases and chronic respiratory system diseases had a positive contribution to life expectancy, which contributed 0.34 years (23.90%), 0.15 years (10.50%), and 0.03 years (2.36%) to the life expectancy growth, respectively. Among which, premature death of cardiovascular and cerebrovascular diseases in men aged 40-55y had a negative contribution to life expectancy (-0.04 years). The probability of premature death of males with diabetes was on the rise (AAPC = 7.1%, 95% CI: 2.8-11.6), which negatively contributed to life expectancy for both males and females, reducing life expectancy by 0.03 years (-2.14%) in Wuxi. Conclusion:The premature death probability of four main NCDs in Wuxi declined consistently from 2008 to 2018, which played a positive role in the growth of life expectancy. Compared with females, males had a higher premature death probability and a slower rate of decline. More intervention and health management of premature male death on cardiovascular and cerebrovascular diseases and diabetes should be conducted to improve life expectancy further.

Objectives: Fitting and forecasting the trend of COVID-19 epidemics. Methods: Based on SEIR dynamic model, considering the COVID-19 transmission mechanism, infection spectrum and prevention and control procedures, we developed SEIR^{+ CAQ} dynamic model to fit the frequencies of laboratory confirmed cases obtained from the government official websites. The data from January 20, 2020 to February 7, 2020 were used to fit the model, while the left data between February 8-12 were used to evaluate the quality of forecasting. Results: According to the cumulative number of confirmed cases between January 29 to February 7, the fitting bias of SEIR^{+ CAQ} model for overall China (except for cases of Hubei province), Hubei province (except for cases of Wuhan city) and Wuhan city was less than 5%. For the data of subsequent 5 days between February 8 to 12, which were not included in the model fitting, the prediction biases were less than 10%. Regardless of the cases diagnosed by clinical examines, the numbers of daily emerging cases of China (Hubei province not included), Hubei Province (Wuhan city not included) and Wuhan city reached the peak in the early February. Under the current strength of prevention and control, the total number of laboratory- confirmed cases in overall China will reach 80 417 till February 29, 2020, respectively. Conclusions The proposed SEIR^{+ CAQ} dynamic model fits and forecasts the trend of novel coronavirus pneumonia well and provides evidence for decision making.

Objective:To compare the prognosis of fluoroucil combined with cisplatin and paclitaxel combined with cisplatin regimens with concurrent radiotherapy in treatment of esophageal squamous cell carcinoma.Methods:A total of 120 patients with esophageal squamous cell carcinoma who were admitted to Anyang Tumor Hospital of Henan Province from December 2012 to November 2018 were randomly divided into group A and group B by using a random number generator. Group A was given cisplatin combined with 5-fluorouracil, and group B was given cisplatin combined with paclitaxel. Both groups had the same radiotherapy regimen, and both used intensity-modulated radiation therapy (IMRT). Completions of 50 Gy radiotherapy and at least one cycle of chemotherapy were considered to be in line with the plan. Survival data was analyzed in the term of intention-to-treat (ITT) and per-protocol (PP) set.Results:Of the 120 patients, 114 patients were treated and the adverse reactions could be evaluated, including 55 cases in group A and 59 cases in group B. The incidence of grade Ⅲ-Ⅳ leukopenia in group B was higher than that in group A [49.2% (29/59) vs. 25.5% (14/55)], and the difference was statistically significant ( χ2 = 6.805, P = 0.012), and there were no statistical differences in the other adverse reactions between the two groups (All P > 0.05). A total of 113 cases can be analyzed for survival. According to ITT analysis, the median progression-free survival (PFS) time in group A and group B was 28.0 months (95% CI 15.5-34.5 months) and 27.0 months (95% CI 17.0-41.0 months), the median overall survival (OS) time was 28.0 months (95% CI 15.8-34.2 months) and not reached, the differences were not statistically significant (both P > 0.05). According to PP analysis, the median PFS time in group A and group B was 28.0 months (95% CI 15.8-34.2 months) and 29.0 months (95% CI 14.9-45.1 months), the median OS time in group A and group B was 28.0 months (95% CI 3.7-52.3 months) and not reached, the differences were not statistically significant (both P > 0.05). Conclusions:The fluorouracil combined with cisplatin regimen and paclitaxel combined with cisplatin regimen with concurrent radiotherapy have similar PFS and OS time in treatment of esophageal squamous cell carcinoma, the adverse reactions are different, but they are all tolerable. In individualized clinical practice, the toxicities and costs of the two regimens can be comprehensively considered.

Objectives:The COVID-19 epidemic has swept all over the world. Estimates of its case fatality rate were influenced by the existing confirmed cases and the time distribution of onset to death, and the conclusions were still unclear. This study was aimed to estimate the age-specific case fatality rate of COVID-19.Methods:Data on COVID-19 epidemic were collected from the National Health Commission and China CDC. The Gamma distribution was used to fit the time from onset to death. The Markov Chain Monte Carlo simulation was used to estimate age-specific case fatality rate.Results:The median time from onset to death of COVID-19 was M=13.77 ( P25- P75: 9.03-21.02) d. The overall case fatality rate of COVID-19 was 4.1 % (95 %CI: 3.7 %-4.4 %) and the age-specific case fatality rate were 0.1 %, 0.4 %, 0.4 %, 0.4 %,0.8 %, 2.3 %, 6.4 %, 14.0 and 25.8 % for 0-, 10-, 20-, 30-, 40-, 50-, 60-, 70- and ≥80 years group, respectively. Conclusions:The Markov Chain Monte Carlo simulation method adjusting censored is suitable for case fatality rate estimation during the epidemic of a new infectious disease. Early identification of the COVID-19 case fatality rate is helpful to the prevention and control of the epidemic.
