With the development of new biological Pulp-capping materials and in-depth research on the defense and repair mech-anisms of pulp-dentin complex to external stimuli,the concept and treatment strategy of vital pulp therapy(VPT)have changed ac-cordingly.Not only young permanent teeth with immature apical foramen、mature permanent teeth with accidental/traumatic pulp perforation and perforation not exceeding 0.5 mm,but also carious pulp-exposed mature permanent teeth and perforation larger than 0.5 mm may successfully preserve pulp.iRoot BP plus,as a novel nano-biomaterial,is widely used in VPT due to its excel-lent biological properties and reparative dentin formation.This review introduces the application of iRoot BP plus in VPT in carious pulp-exposed mature permanent teeth,in order to provide reference for clinical application and related basic research.

Objective:To assess the attitudes toward and factors influencing starting insulin use among community-based patients with type 2 diabetes (T2D).Methods:A cross- sectional study. This secondary analysis used baseline data from patients with T2D recruited through convenience sampling from a community-based peer support intervention study implemented in nine community health service centers in Shanghai since 2017. Attitudes toward insulin use were assessed using the Chinese Attitudes to Starting Insulin Questionnaire (Ch-ASIQ); the higher the score, the more negative the attitude toward starting insulin use. Multiple linear regression was used to analyze the factors influencing attitudes toward starting insulin use.Results:A total of 336 patients with T2D were included in the survey. The patients had a mean age of (67.7±7.9) years, mean disease duration of (13.62±7.73) years, relatively low levels of depression [Patient Health Questionnaire 8 (PHQ-8): 2 (0, 5)] and diabetes distress [Diabetes Distress Scale 4 (DDS-4): 1.97±0.95], and suboptimal target achieving rates of risk factors including body mass index, blood pressure, blood glucose, and lipid levels. The total score on the Ch-ASIQ among all patients was 1.84±0.55. Multivariate analyses showed that refusing insulin use was positively significantly associated with higher scores on the Ch-ASIQ and the three sub-dimensions of "Factors promoting self-efficacy," "Fear of pain or needles," and "Time and family support" [ β (95% CI): 0.515 (0.355-0.674), 0.728 (0.470-0.986), 0.273 (0.030-0.515), 0.909 (0.606-1.213), all P<0.05]. In addition, disease duration [ β (95% CI):-0.011 (-0.019 to -0.004)] was independently negatively associated with the Ch-ASIQ score. In comparison, age [ β (95% CI): 0.011 (0.003-0.018)], DDS-4 [0.129 (0.069-0.190)], and PHQ-8 [0.015 (0.000-0.029)] were independently positively associated with the Ch-ASIQ score (all P<0.05). There were slight differences in the factors influencing the four sub-dimensions of the Ch-ASIQ scale. Conclusions:Community-based patients with T2D had moderate negative attitudes toward starting insulin treatment. Refusing insulin use, shorter diabetes duration, older age, higher diabetes distress, and higher levels of depression were associated with higher negative attitudes towards starting insulin use.

Objective:To investigate the efficacy of posterior cranial fossa in- situ floating bone flap osteotomy in the treatment of syndromic craniosynostosis(SCS). Methods:The clinical data of SCS children who underwent posterior cranial fossa in- situ floating bone flap osteotomy at the Shanghai Children’s Medical Center, Shanghai Jiao Tong University School of Medicine from April 2020 to August 2022 were retrospectively analyzed. The surgical procedures were as follows. The occipital bone was cut into several mosaic bone flaps of varying sizes, without peeling it off the dura, which were left as a small free floating bone flap. The anteroposterior cranial diameter, cranial height, intracranial volume, and degree of improvement in tonsillar herniation and hydrocephalus of the children (hydrocephalus quantification was performed using the ratio of the ventricular diameter to the biparietal diameter)were measured preoperatively, 7 days postoperatively, 3 months postoperatively, and at the last follow-up (at least 12 months after the operation) to evaluate the surgical outcomes. The measurement data of normal distribution were expressed as Mean±SD. The paired t-test was used for comparison within the repeated measurement data groups at the two time points. One-way repeated measures analysis of variance (ANOVA) was performed on the repeated measurement data at multiple time points, and pairwise comparisons in post hoc tests were corrected using the Bonferroni method. Results:A total of 17 pediatric patients with SCS were included, comprising 10 males and 7 females, with ages ranging from 4 to 18 months (mean age: 9.5 months). Among them, 12 patients were complicated with Chiari malformation and hydrocephalus (1 severe case, 8 moderate cases, and 3 mild cases). Postoperative follow-up lasted 12 to 35 months, with an average of 17 months. After surgery, the posterior cranial appearance of the children was enlarged, with increased convexity of the occiput and a full contour. At the last follow-up, the middle cranial height [(107.80±10.72) mm vs. (102.82±10.09) mm, P<0.05], the posterior cranial height [(124.91±10.40) mm vs. (107.58±13.46) mm, P<0.01] and anteroposterior diameter [(153.30±11.26) mm vs. (123.64±17.44) mm, P<0.01] as well as the intracranial volume [(1 317.92±225.77) cm 3 vs. (1 014.93±231.81) cm 3,P<0.01] were increased compared with the preoperative period, and the average improvement rate of intracranial volume was 37.0% (18.1%-79.2%). Among the 12 cases of tonsillar herniation, 7 cases had improvement. Moreover, all the 12 cases of hydrocephalus witnessed a mitigation in severity, from (46.33±9.34)% preoperatively to (35.24±9.88)% postoperatively, with a statistically significant difference ( P<0.01). Conclusion:Posterior cranial fossa in- situ floating bone flap osteotomy can effectively improve the appearance of patients with SCS, increase the intracranial volume, relieve the degree of hydrocephalus, and reduce the intracranial pressure.

Objective:To investigate the lung cancer incidence and mortality in 2016 and their trends from 2002 to 2016 in shanghai. Methods:The data of incidence and death on lung cancer in shanghai from 2002 to 2016 were obtained from the Shanghai Municipal Center for Disease Control and Prevention population-based cancer registry and Vital Statistics System.Lung Cancer incidence and mortality stratified by age of diagnosis or death,gender and age-group were analyzed.The number of cases and deaths,proportion,crude rates,age-specific rates,age-standardized rates,corresponding truncated age-standardized rates(35-64 years)and cumulative rates were calculated.Segi's 1960 world standard population was used for calculating age-standardized rates of incidence and mortality as well as truncated age-standardized rates.Trends in age-standardized rates of incidence and death for lung cancer in Shanghai from 2002-2016 were estimated by Joinpoint analysis and characterized by the annual percent change(APC). Results:The new lung cancer cases and deaths were 14 395 and 9 170 in Shanghai in 2016.The crude rate of incidence was 99.41/105,and the age-standardized rate of incidence was 39.76/105.New cases of lung cancer accounted for 19.34％of all malignant tumors in shanghai,ranking the first in the incidence spectrum of malignant tumors.The crude rate of mortality was 63.33/105,and the age-standardized rate was 21.57/105.Deaths of lung cancer accounted for 24.78％of all malignant tumor deaths in shanghai,ranking the first in the mortality spectrum of malignant tumors.The age-standardized rates of incidence and mortality for males were higher than those for females.The age-specific numbers and rates of incidence and mortality increased with age.The age-specific number and rate of incidence reached the peak at the age group of 60-64 years and 80-84 years respectively,and those of mortality peaked at the age group of 80-84 years and older than 85 years respectively.The incidence of lung cancer increased from 33.70/105 in 2002 to 39.76/1 05 in 2016 in Shanghai.Joinpoint analyses showed that the age-standardized rate of lung cancer incidence remained stable from 2002 to 2010(APC=-0.79,t=-1.46,P=0.175)but showed a significant upward trend with an average annual increase rate of 5.12％from 2010 to 2016(APC=5.12,t=6.97,P＜0.001).The standardized mortality showed a downward trend with an average annual decrease rate of 0.87％from 2002 to 2016(APC=-0.87,t=-2.87,P=0.013). Conclusion:The incidence of lung cancer in Shanghai during 2002-2016 presented an upward trend while the mortality of lung cancer showed a gradual downward trend.There are differences in the incidence and mortality of lung cancer among different gender and age groups.

Objective:To investigate the effects of miRNA-499a-5p targeting CD38 on cardiomyocyte injury induced by hydrogen peroxide (H 2O 2) and the possible mechanism. Methods:H9c2 cardiomyocytes were cultured in vitro and induced with H 2O 2 to establish the cardiomyocyte injury model. Four groups including control, H 2O 2, H 2O 2+ negative control (NC) and H 2O 2+ miRNA-499a-5p groups were set up. Real-time quantitative PCR (RT-qPCR) and Western blot were used to detect the expression of miRNA-499a-5p and CD38 in cardiomyocytes, respectively. MTT assay was used to measure the survival rates of cardiomyocytes. The levels of reactive oxygen species (ROS) and the activity of lactate dehydrogenase (LDH) were analyzed with test kits. Annexin V-FITC/PI double staining method was used to detect the apoptosis rates of cardiomyocytes. Western blot was used to detect the expression of B-cell lymphoma/leukemia-2 (Bcl-2), Bcl-2-related X protein (Bax), phosphoinositide 3-kinase (PI3K), phosphorylated PI3K (p-PI3K), protein kinase B (Akt) and phosphorylated Akt (p-Akt). Dual luciferase reporter assay was used to detect the targeting relationship between miRNA-499a-5p and CD38. Results:Compared with the control group, the expression of miRNA-499a-5p, Bcl-2, p-PI3K and p-Akt and the survival rate of cardiomyocytes were significantly reduced in the H 2O 2 group ( P<0.05), while the expression of CD38 and Bax, ROS level, LDH activity and the apoptosis rate were significantly increased ( P<0.05). Compared with the H 2O 2 group, the expression of miRNA-499a-5p, Bcl-2, p-PI3K and p-Akt and the survival rate of cardiomyocytes were significantly increased in the H 2O 2+ miRNA-499a-5p group ( P<0.05), while the expression of CD38 and Bax, ROS level, LDH activity and the apoptosis rate were significantly decreased ( P<0.05). Dual luciferase reporter assay confirmed that CD38 was a target gene of miRNA-499a-5p. Conclusions:miRNA-499a-5p could alleviate H 2O 2-induced cardiomyocyte injury by inhibiting the expression of CD38 and the PI3K/Akt signaling pathway might be involved.

Objective:To study the risk of malnutrition and related factors of cancer patients in community of Shanghai.Methods:From October 2018 to January 2019, four communities, Pengpu New Village Street, Pengpu Town, Jiangning Road Street, and Caojiadu Street, from 14 communities in Jing ′an District, Shanghai City, were selected by using a random cluster sampling method based on the Shanghai Cancer Registration and reporting system. All cases of malignant tumors and benign tumors of the central nervous system were included. A total of 4 396 questionnaires were distributed. After the exclusion of 9 invalid questionnaires, 3 310 valid questionnaires were included with a rate of 99.73%. A self-designed questionnaire was used to collect data including basic demographic characteristics, history of malignant, physical and psychological pain, nutritional demands and cognitive status. Malnutrition Universal Screening Tools (MUST) was used to analyze the nutritional risk of cancer patients in the community. Multivariate logistic regression model was applied to analyze potential factors.Results:Among the 3 310 cancer patients who completed the survey, the average age of study participants was (64.05±13.02), and 1 467 cases (44.32%) were males. The incidence rate of nutritional risk was 12.84% (425/3 310). The result of logistic regression analysis showed that compared with male, other cancer patients and no physical pain, the risk factors of the occurrence of nutritional included: female ( OR=1.53,95% CI:1.23-1.92), head and neck malignant tumors ( OR=1.42,95% CI:1.07-1.90), bronchus/lung malignant tumors ( OR=1.93,95% CI:1.43-2.61), liver, biliary/pancreatic malignant tumors ( OR=2.11,95% CI:1.21-3.65) and upper gastrointestinal malignant tumors ( OR=6.04,95% CI:4.31-8.46), patients with physical pain ( OR=1.39,95% CI:1.02-1.89). Conclusion:Nutritional risk of cancer patients is higher in community of Shanghai. Gender, location of tumors and physical pain are associated with the occurrence of nutritional risk.
