Objective To examine the toxicity and sublethal effects of calcium cyanamide against susceptible isolates of Aedes albopictus, so as to provide insights into rational use of calcium cyanamide for integrated management of Ae. albopictus. Methods The sublethal concentrations [30% lethal concentration (LC₃₀) and median lethal concentration (LC₅₀)] of calcium cyana mide against susceptible strains of Ae. albopictus were determined using the larval immersion test. With 100 mL of dechlorinated water as the control group, after the larvae of susceptible strains of Ae. albopictus were immersed in calcium cyanamide for 24 hours, the pupation rate, pupation duration, emergence rate, number of eggs laid, percentage of eggs hatched, and lifespan of Ae. albopictus were calculated and compared post-treatment with calcium cyanamide at different sublethal concentrations. The midgut tissues of larvae of susceptible strains of Ae. albopictus treated with 100 mg/L calcium cyanamide were sampled for pathological sectioning to observe midgut tissue damages. To evaluate the residual activity, 100 larvae of susceptible strains of Ae. albopictus were treated with 200 mg/L and 500 mg/L calcium cyanamide, and the mortality of larvae was calculated every 24 hour, with dead larvae replaced until no larval death. Results The regression equation for the toxicity of calcium cyanamide against larvae of susceptible strains of Ae. albopictus was y = -9.441 + 4.657x, with an LC₅₀ of 106.42 mg/L [95% confidence interval (CI): (94.64, 118.36) mg/L] and an LC₃₀ of 82.17 mg/L [95% CI: (94.64, 118.36) mg/L], respectively. After larvae of susceptible strains of Ae. albopictus were treated with sublethal concentrations (LC₃₀ and LC₅₀) of calcium cyanamide for 24 hours, there were reduced pupation and emergence rates of larvae (all P values < 0.000 1), prolonged pupal stage (both P values < 0.000 1), reduced numbers of eggs laid by survival female Ae. albopictus (both P values < 0.000 1), reduced percentages of eggs hatched by Ae. albopictus eggs (both P values < 0.000 1), and reduced median survival period of survival female Ae. albopictus (χ² = 9.36 and 20.33, both P values < 0.01) in the LC₃₀ and LC₅₀ groups relative to the control group. There was a numerical decline in the median survival period of survival female Ae. albopictus in the LC₃₀ groups relative to the control group (χ² = 2.42, P > 0.05), and there was a significant decline in the median survival period of survival female Ae. albopictus in the LC₅₀ group relative to the control group (χ² = 11.42, P < 0.01). Histopathological examinations showed severe damages to the midgut tissues of larvae of susceptible strains of Ae. albopictus, and residual activity assay revealed that the mortality of larvae of susceptible strains of Ae. albopictus was both 0 on day 32 post-treatment with calcium cyanamide at a concentration of 200 mg/L and on day 70 post-treatment with calcium cyanamide at a concentration of 500 mg/L, showing complete loss of the larvicidal activity of calcium cyanamide. Conclusions Calcium cyanamide is highly toxic against susceptible strains of Ae. albopictus, and calcium cyanamide at sublethal concentrations (LC₃₀ and LC₅₀) may inhibit growth, development, and reproductive capability of susceptible strains of Ae. albopictus, and shorten the lifespan of adult mosquitoes.

Objective: To compare and analyze the antibacterial effects of platelets against five common clinical pathogenic bacteria including MRSA, SE, SA, E. coli, and CRKP, and to preliminarily explore the role of DCD sensitivity in the observed variations of antibacterial effects. Methods: The same number of platelets were used to establish co-culture systems of platelets and platelet lysates with the five pathogenic bacteria. The antibacterial effects of platelets and platelet lysates on the five pathogenic bacteria were evaluated by observing the turbidity of the bacterial solution, measuring the OD value of the bacterial solution and counting the colonies. The supernatant protein of platelets co-cultured with MRSA was collected for quantitative proteomics analysis to explore the important antibacterial proteins of platelets. The content of DCD in the supernatant after co-culture of platelets and platelet lysates with the five pathogenic bacteria was detected by ELISA to preliminarily analyze the reasons for the different antibacterial effects of platelets on the five pathogenic bacteria. Results: Compared with the control group of MRSA, SA, and SE, the turbidity of the bacterial solution decreased after co-culture of platelets and platelet lysates with MRSA, SA, and SE for 12 h, and the OD value and colony count were significantly reduced (P<0.05). The turbidity of the bacterial solution did not change significantly after co-culture of platelets and platelet lysates with E. coli for 24 h, but the OD value decreased (P<0.05), and the colony count decreased to 10 CFU/mL but the difference was not statistically significant (P>0.05). Compared with the control group of CRKP, the turbidity, OD value, and colony count of the bacterial solution did not change significantly after co-culture of platelets and platelet lysates with CRKP (P>0.05). Proteomics results showed that after co-culture with MRSA, important proteins related to platelet activation, including collagen, fibrinogen, von Willebrand factor, integrin αIIbβ3, platelet glycoprotein V and IV were significantly up-regulated. ELISA results showed that after co-culture with the five pathogenic bacteria, platelets could secrete a large amount of DCD, with the content around 3 μg/mL. Conclusion: The antibacterial effect of platelets on Gram-positive bacteria MRSA, SA, and SE is better than that on Gram-negative bacteria E. coli and CRKP, and platelets have the best antibacterial effect on MRSA. The differences in antibacterial effects of platelets on the five pathogenic bacteria may be related to the sensitivity of DCD antibacterial peptides to the five pathogenic bacteria.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective To investigate the efficacy and safety of camrelizumab monoclonal antibody combined with molecular-targeted therapy in elderly patients with unresectable or advanced hepatocellular carcinoma(HCC).Methods A retrospective analysis was performed for the patients with unresectable/advanced HCC who attended six hospitals from January 1,2019 to March 31,2021,and all patients received camrelizumab monoclonal antibody treatment,among whom 84.8%also received targeted therapy.According to the age of the patients,they were divided into elderly group(≥65 years)and non-elderly group(＜65 years).The two groups were assessed in terms of overall survival(OS),progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),and immune-related adverse events(irAE).The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups;the independent samples t-test was used for comparison of normally distributed continuous data,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups.The Kaplan-Meier method was used for survival analysis,and the log-rank test was used for comparison of survival curves.Univariate and multivariate Cox proportional hazards regression analyses were used to determine the independent influencing factors for PFS and DCR at 6 months.Results A total of 99 HCC patients were enrolled,with 27 in the elderly group and 72 in the non-elderly group.The elderly group had an OS rate of 67.8%,an ORR of 44.4%,and a DCR of 74.1%at 12 months and a median PFS of 6.4(95%confidence interval[CI]:3.0-12.4)months,with no significant differences compared with the non-elderly group(all P＞0.05).The median OS was unavailable for the elderly group,while the non-elderly group had an OS of 18.9(95%CI:13.0-24.8)months;there was no significant difference between the two groups(P=0.485).The univariate and multivariate Cox regression analyses showed that major vascular invasion(MVI)was an independent risk factor for PFS(hazard ratio[HR]=2.603,95%CI:1.136-5.964,P=0.024)and DCR(HR=3.963,95%CI:1.671-9.397,P=0.002)at 6 months,while age,sex,etiology of HBV infection,presence of extrahepatic metastasis,Child-Pugh class B,and alpha-fetoprotein＞400 ng/mL were not associated with PFS or DCR at 6 months.For the elderly group,the incidence rates of any irAE and grade 3/4 irAE were 51.9%and 25.9%,respectively,with no significant differences compared with the non-elderly group(P＞0.05),and skin disease was the most common irAE in both groups(39.4%).Conclusion Camrelizumab monoclonal antibody combined with molecular-targeted therapy has similar efficacy and safety in patients with unresectable/advanced HCC aged≥65 years and those aged＜65 years.MVI is associated with suboptimal response to immunotherapy and poor prognosis.
