Objective To explore the risk factors for clinical severity in patients with hypertriglyceridemic acute pancreatitis(HTG-AP).Methods A retrospective cohort study was conducted to collect the clinical data of HTG-AP patients admitted to the First Hospital of Putian City from June 2022 to December 2023.Patients were divided into a non-severe group(132 cases)and a severe group(22 cases)according whether they developed complications such as organ dysfunction and pancreatitcs necrosis.The differences in baseline characteristics between the two groups were compared,such as general data[including gender,age,body mass index(BMI),history of hypertension and diabetes],laboratory examination indicators[including glycated hemoglobin(HbA1c),white blood cell count(WBC),C-reactive protein(CRP),procalcitonin(PCT),systemic immune-inflammation index(SII),serum albumin(Alb),serum mylase to serum calcium ration(ACR),D-dimer,platelet count(PLT),total cholesterol(TC),triglycerides(TG),high-density lipoprotein(HDL),and low-density lipoprotein(LDL)].Univariate and multivariate Logistic regression analyses were used to screen for independent risk factors for clinical severity in HTG-AP patients,and the predictive efficacy of various risk factors for clinical severe progression of HTG-AP was evaluated using the receiver operator characteristic curve(ROC curve).Results A total of 154 patients were included,including 131 males and 23 females;the age range was 18-67 years,average was(39.00±8.74)years.A total of 22 patients developed clinical severity,with an incidence rate of 14.3%.There were no statistically significant differences between the two groups in terms of gender,age,BMI,hypertension,diabetes,HbA1c,WBC,CRP,Alb,PLT,TC,TG,HDL,and LDL.Compared with the non-severe group,the levels of PCT,D-dimer,ACR,and SII were significantly higher in the severe group[PCT(μg/L):0.34(0.12,0.49)vs.0.09(0.05,0.35),D-dimer(μg/L):1 010(340,1 790)vs.310(200,700),ACR:201.10(121.71,568.53)vs.61.79(27.99,153.77),SII:2 076.57(1 187.06,3 665.47)vs.1 033.95(717.95,1 466.76),all P<0.05].Multivariate Logistic regression analysis showed that ACR at admission was an independent risk factors for the development of clinical severity in HTG-AP patients(P<0.05).ROC curve analysis indicated that ACR has certain value in predicting clinical severity in HTG-AP area under the curve(AUC)=0.787[95%confidence interval(95%CI)was 0.685-0.890],P<0.001,and when the optimal cut-off value was set at 79.663,its sensitivity was 90.9%and specificity was 58.3%.Conclusion An abnormally elevated ACR at admission in HTG-AP patients is significantly associated with the risk of clinical severity and can be used as potential predictive indicator for early identification of high-risk patients.

Objective:To develop the Nurse Parenting Stress Scale and evaluate its reliability and validity.Methods:Based on Abidin's Parenting Stress Theory, scale items were generated through literature review and semi-structured interviews. The initial version was constructed via Delphi expert consultation. Using a convenience sampling method, nurses from six hospitals in Shandong Province were surveyed between August and October 2024. The first survey collected 314 questionnaires (308 valid, effective recovery rate 98.1%) for item analysis and exploratory factor analysis (EFA). The second survey collected 458 questionnaires (447 valid, effective recovery rate 97.6%) for confirmatory factor analysis (CFA) .Results:The Nurse Parenting Stress Scale consists of 4 dimensions and 31 items. The Cronbach's α coefficient of the total scale was 0.951, split-half reliability was 0.782, and test-retest reliability was 0.926. EFA extracted four common factors explaining 70.241% of the cumulative variance. CFA demonstrated a good model fit. The item-level content validity index ( I- CVI) ranged from 0.889 to 1.000, the scale-level universal agreement content validity index ( S- CVI/ UA) was 0.903, and the scale-level average content validity index ( S- CVI/ Ave) was 0.989. Conclusions:The Nurse Parenting Stress Scale shows strong reliability and validity and can serve as an effective tool for assessing parenting stress among nurses.

Oral diseases concern almost every individual and are a serious health risk to the popula-tion.The restorative treatment of tooth and jaw defects is an important means to achieve oral function and support the appearance of the contour.Based on the principle of"learning from the nature",Deng Xu-liang's group of Peking University School and Hospital of Stomatology has proposed a new concept of"microstructural biomimetic design and tissue adaptation of tooth/jaw materials"to address the worldwide problems of difficulty in treating dentine hypersensitivity,poor prognosis of restoration of tooth defects,and vertical bone augmentation of alveolar bone after tooth loss.The group has broken through the bottle-neck of multi-stage biomimetic technology from the design of microscopic features to the enhancement of macroscopic effects,and invented key technologies such as crystalline/amorphous multi-level assembly,ion-transportation blocking,and multi-physical properties of the micro-environment reconstruction,etc.The group also pioneered the cationic-hydrogel desensitizer,digital stump and core integrated restora-tions,and developed new crown and bridge restorative materials,gradient functionalisation guided tissue regeneration membrane,and electrically responsive alveolar bone augmentation restorative membranes,etc.These products have established new clinical strategies for tooth/jaw defect repair and achieved inno-vative results.In conclusion,the research results of our group have strongly supported the theoretical im-provement of stomatology,developed the technical system of oral hard tissue restoration,innovated the clinical treatment strategy,and led the progress of the stomatology industry.

Background Ozone (O₃) pollution has gradually become a primary problem of air pollution in recent years. Conducting epidemiological studies on the correlation between O₃ concentration variation and risk of cardiovascular and cerebrovascular diseases can provide reference data for O₃ risk assessment and related policy making. Objective To quantitatively evaluate the effects of O₃ exposure on mortalities of cardiovascular and cerebrovascular diseases among residents in Minhang District, Shanghai. Methods Data of mortalities of cardiovascular and cerebrovascular diseases, air pollutants, and meteorological factors in Minhang District of Shanghai from January 1, 2016 to December 31, 2021 were collected. Associations between O₃ concentration and the mortalities due to total cardiovascular and cerebrovascular diseases, coronary heart disease, and stroke were analyzed by generalized additive models with a quasi Poisson distribution with different lag patterns, such as current day effect (lag0), single-day lag effects (lag1-lag3), and cumulative lag effects (lag01-lag03). The subgroup analyses of age, sex, and season were conducted. Furthermore, temperature was divided into low, middle, and high levels based on the 25th percentile (P₂₅) and the 75th percentile (P₇₅) to perform hierarchical analyses. Increased excess risks (ER) of death from target diseases caused by a 10 µg·m⁻³ increase in daily maximum 8 h concentration of O₃ (O₃-8 h) and their 95% confidence intervals (CI) were used to indicate the effects of O₃. Results The associations between O₃ and the risks of death from cardiovascular and cerebrovascular diseases were statistically significant at lag2, lag3, lag02, and lag03 (P<0.05), with the greatest effect size observed at lag03. The ER values of death from cardiovascular and cerebrovascular diseases in general population, male residents, and people aged 65 years and older, from coronary heart disease in male residents, and from stroke in general population increased by 1.02% (95%CI: 0.36%, 1.69%), 1.40% (95%CI: 0.47%, 2.34%), 0.87% (95%CI: 0.19%, 1.55%), 1.96% (95%CI: 0.49%, 3.44%), and 1.02% (95%CI: 0.07%, 1.98%) for a 10 µg·m⁻³ increase in O₃-8 h concentration at lag03, respectively. During the warm season (from April 1 to September 30), the ER values of death from cardiovascular and cerebrovascular diseases and coronary heart disease per 10 µg·m⁻³ increase in O₃ were 1.18% (95%CI: 0.33%, 3.33%) and 2.69% (95%CI: 0.39%, 5.03%), while the O₃ effect was only statistically significant on cardiovascular and cerebrovascular diseases during the cold season (from October 1 to March 31 next year). At the middle and high temperature levels, the ER values of death from cardiovascular and cerebrovascular diseases increased by 1.63% (95%CI: 0.32%, 2.96%) and 1.14% (95%CI: 0.17%, 2.12%) respectively. The two-pollutant models showed similar results after including other pollutants (carbon monoxide, nitrogen dioxide, sulfur dioxide, fine particulate matter, or inhalable particulate matter). Conclusion Ambient O₃ pollution may increase the mortality risks of cardiovascular and cerebrovascular diseases, coronary heart disease, and stroke in Minhang District of Shanghai.

Objective To study the changes in peripheral blood T lymphocytes in patients with ankylosing spondylitis and their correlation with the disease's severity and prognosis.Methods We selected 120 patients with ankylosing spondylitis treated between January 2020 and March 2023 as the research group and 120 healthy people who had medical examinations in the same period as the health group.We detected the changes in CD4+,CD8+and CD4+/CD8+values of peripheral blood T lymphocyte subsets with flow cytometry,compared the differences in T lymphocyte subsets between the two groups,and analyzed the correlation with the disease severity of the patients.All the 120 patients with ankylosing spondylitis were followed up for 6 months after treatment to assess their prognosis.General information and T lymphocyte sub-groups CD4+,CD8+level,CD4+/CD8+value changes were compared among patients with different prognosis.We analyzed the value of T lymphocyte sub-groups in predicting the prognosis of patients with ankylosing spondylitis.Results In the research group CD4+and CD4+/CD8+were lower but CD8 1 was higher than those in the healthy group(P＜0.05).CD4+and CD4+/CD8 were lower but CD8+was higher in patients with advanced ankylosing spondylitis than in early and mid-term patients(P＜0.05).The ROC curve analysis showed that the AUC of CD4+,CD8+,and CD4+/CD8+combined diagnosis of ankylosing spondylitis patients was 0.878,with higher diagnostic sensitivity than that of the single diagnosis(P＜0.05).In the poor prognosis group,CD8+was higher than that in the excellent prognosis group,but CD4+and CD4+/CD8 value were lower than the latter(P＜0.05).The results of Pearson test showed that CD4+and CD4+/CD8+were negatively correlated with the prognosis of patients with ankylosing spondylitis(r=-0.568,-0.656,P＜0.001).CD8+was positively correlated with the prognosis of patients with ankylosing spondylitis(r=0.623,P＜0.001).ROC curve analysis showed that the AUC of the combined diagnosis of CD4+,CD8+and CD4+/CD8+for ankylosing spondylitis patients was 0.910,and the diagnostic sensitivity was higher than that of single diagnosis(P＜0.05).Conclusion The abnormal levels of peripheral blood T lymphocyte subsets in patients with ankylosing spondylitis are closely related to the severity and prognosis of the disease,and can be used as a reference indicator for diagnosing the severity and prognosis of ankylosing spondylitis.

Objective:To elucidate the phenomenon that epileptic seizure occurs in patients with epilepsy without definite diagnosis when driving a motor vehicle and its hazards.Methods:From January 2020 to June 2022, 7 epileptic patients who experienced traffic accidents caused by seizures were selected from the First Affiliated Hospital of Soochow University, and their demographic data, traffic accident related data and epilepsy diagnosis and treatment data were summarized and analyzed.Results:A total of 7 adult patients with epilepsy were collected, including 6 males, 4 of whom had been driving for more than 10 years. Among them, 1 patient drove a bus, and the other 6 patients drove private cars. Totally 5/7 of the accidents resulted in personal injury, and 3/7 of the accidents resulted in personal death. In 5 patients, video electroencephalogram showed interictal epileptiform discharges. In 2 patients, the imaging findings suggested the presence of cerebral cortical lesions that may lead to seizures. In terms of the form of seizure, 3 patients′ seizure type was focal to bilateral tonic-clonic, and the other 4 patients were very probable to be focal impaired awareness seizure.Conclusions:Undiagnosed epileptic seizures lead to traffic accidents, endanger patients and public safety, which need to attract attention from both doctors and patients, as well as the whole society.

【Objective】 To investigate the current situation concerning volume control of red blood cells in additive solution produced by blood service in Chongqing, and to lay a foundation for promoting the homogenization of preparation process of red blood cells in additive solution. 【Methods】 A questionnaire was designed to investigate the factors related to the preparation of red blood cells in additive solution. The questionnaire was sent by Chongqing Association of Blood Transfusion via E-mail to 18 blood services in the city, and the collected data was sorted, revised and analyzed by research team. 【Results】 A total of 18 blood services(including 1 blood center + 1 sub-center, 6 central blood stations and 11 central blood banks) returned the questionnaires. The results showed that there were differences among blood services across Chongqing, regarding the centrifugal parameters during preparation, the operation mode and monitoring situation of the capacity control during preparation, and the formulation of the capacity standard of red blood cells in additive solution etc. 【Conclusion】 The preparation process of red blood cells in additive solution, produced by Chongqing blood services, should be further standardized, and the capacity control method of this product in Chongqing should be gradually unified to achieve regional homogeneity and to ensure blood safety.

Objective:To observe any therapeutic effect of repeated transcranial direct current stimulation (tDCS) on rats modeling neuropathic pain and explore possible mechanisms.Methods:Forty adult male Sprague-Dawley rats were randomly divided into a normal group ( n=10), a sham operation group ( n=10), a treatment group ( n=10) and a sham treatment group ( n=10). A model of chronic constriction injury of the sciatic nerve was established in the latter two groups. Fourteen days after the modeling, the treatment group was given tDCS for 8 consecutive days, while the sham treatment group received sham stimulation, and the other 2 groups did not receive any intervention. Von Frey and hotplate tests were used to test the rats′ pain thresholds 1 day before, as well as 14 and 22 days after the surgery (i.e., 8 days after the end of the treatment). Spinal cord tissue samples were taken to detect the protein expressions of N-methyl-D-aspartic acid receptor 2B, gamma-aminobutyric acid receptor types A (GABA a-R) and B (GABA b-R) using western blotting. Results:On the 14th day after the operation the average 50% MWT and WTL values of the sham treatment and treatment groups had decreased significantly compared with the sham operation group. By the 22nd day the average 50% MWT and WTL values of the treatment group were significantly higher than those of the sham treatment group, but there was no significant change in the treatment group′s average WTL between the 21st and 22nd days. On the 22nd day after the operation the average NR2B-NMDA-R level of the sham treatment group were significantly higher than that of the sham operation group, while the average GABA a-R and GABA b-R levels were significantly lower. At the same time point the treatment group′s average NR2B-NMDA-R level had decreased significantly compared to the sham treatment group, while the average GABA a-R level had increased significantly. There was no significant difference in average GABA b-R level between the treatment group and the sham treatment group at that point. On the 22nd day there was also no significant difference in the average NR2B-NMDA-R level between the treatment group and the sham operation group. Conclusions:Repeated tDCS can effectively relieve neuropathic pain. The relief of hyperalgesia is more significant than that of mechanical allodynia. A possible mechanism may be the down-regulation of spinal NR2B-NMDA-R to normal levels and modest up-regulation of GABA a-R.
