Thyroid dysfunction (TD) is one of the commonest endocrine immunotherapy-related adverse events (IRAEs) during cancer patients' treatment with immune checkpoint inhibitors (ICIs). In the hope that cooperation between departments will be enhanced to alleviate the side effect of immunotherapy which thyroid dysfunctions can cause, this review is contributed to make more endocrinologists and oncologists acknowledge and master clinical characteristics, diagnostic methods and therapeutic strategies of thyroid IRAEs, by the introduction of its pathogenesis, epidemiological features, diagnosis, treatment and prognosis.

Objective:To analyze and compare the association between different obesity-related indices and vitamin D deficiency in middle-aged and elderly population dwelled in Lanzhou city.Methods:From May, 2011 to September, 2012, middle-aged and elderly individuals with complete baseline data were included via randomly cluster sampling from 3 communities in Lanzhou. The subjects were divided into 4 subgroups by vitamin D levels and various obesity-related indices were compared across subgroups with the same gender. The relationship between the obesity-related indices and the severity of vitamin D deficiency was analyzed using Spearman correlation analysis, and the effects of different obesity-related indices on the severity of vitamin D deficiency was analyzed using multivariate logistic regression analysis.Results:A total of 9 437 residents were included. The overall prevalence of vitamin D deficiency was 97.7%. Compared with the group with lower vitamin D level, participants in the group with higher vitamin D level showed evidently lower body mass index (BMI), waist circumference (WC), lipid accumulation product (LAP), visceral adiposity index (VAI) and triglyceride/ high density lipoprotein cholesterol (TG/HDL-C) ratio in the total population and females, while only WC, LAP, VAI and TG/HDL-C in the males (all P<0.05). Spearman correlation analysis showed that BMI, WC, LAP, VAI and TG/HDL-C were positively correlated with the severity of vitamin D deficiency in the total population and the females, while only LAP, VAI and TG/HDL-C in the males (all P<0.05) . Multivariate logistic regression analysis showed that higher levels of these obesity related indices were correlated with more severe vitamin D deficiency in the total population and the females, while only higher LAP, VAI and TG/HDL-C in the males (all P<0.05). The effects of higher LAP was the most prominant in the total population ,the females and the males. Conclusion:Various obesity phenotypes are closely related to vitamin D deficiency in middle-aged and elderly women, while only visceral obesity and abnormal lipid metabolism are related to vitamin D deficiency in middle-aged and elderly men, with LAP being the most important influencing factor.

Objective To investigate the effect of oral fish oil on wound healing and related indexes in patients with diabetic foot ulcer(DFU).Methods A randomized,double-blind,placebo-controlled design was used to recruit 68 patients with DFU aged 18-80 years old in the hospital,and the baseline clinical data of the patients were collected.The patients were randomly divided into experimental group(32 cases,fish oil soft capsule,3 g/d)and control group(33 cases,corn oil soft capsule,3 g/d)by random number generated by Ex-cel,and the intervention lasted for 12 weeks.The primary endpoints included the proportion of complete wound healing and healing area≥50%.The secondary endpoints included wound area,healing time,inflamma-tion index,glucose metabolism index,nutrition related index and wound reinfection.Additionally,the influen-cing factors of wound healing were analyzed.Results After intervention,the proportion of complete wound healing and healing area≥50%in the experimental group was significantly higher than that in the control group(P=0.007,0.039).In the subjects with complete wound healing,the mean healing time in the experi-mental group was shorter than that in the control group,but the difference was not statistically significant(P=0.132).The reduction area of wound area in the experimental group was significantly larger than that in the control group(P=0.045).The decrease of interleukin(IL)-6 and IL-8 in the experimental group was significantly higher than that in the control group(P<0.05).There was no significant difference in the reduc-tion of C-reactive protein(CRP),tumor necrosis factor-α(TNF-α),neutrophil-to-lymphocyte ratio(NLR),glycated hemoglobin A1c(HbA1c)and platelet-to-lymphocyte ratio(PLR)between the two groups(P>0.05).The improvement of prealbumin(PA)in the experimental group was higher than that in the control group,but the difference was not statistically significant(P>0.05).Multivariate logistic regression analysis showed that oral fish oil intervention(OR=6.771,95%CI:1.787-25.652),HbA1c(OR=4.149,95%CI:1.026-16.770)and ulcer type(OR=4.319,95%CI:1.026-18.173)were the influencing factors of wound healing(P<0.05).Conclusion Oral fish oil promotes wound healing in patients with DFU,which may be re-lated to improving the level of chronic inflammation in the body.

OBJECTIVE To systematically evaluate the efficacy and safety of vonoprazan in the treatment of gastroesophageal reflux disease, and to provide evidence-based reference for clinical drug use. METHODS Randomized controlled trials (RCTs) about vonoprazan (trial group) versus placebo or proton pump inhibitor (control group) were searched in PubMed, the Cochrane Library, Web of Science, CNKI, Wanfang, VIP and CBM databases from the inception to June, 2022. After literature screening and data extraction, the qualities of included literature were evaluated with bias assessment tool recommended by Cochrane system evaluator manual 5.1.0. Meta-analysis, sensitivity analysis and publication bias analysis were conducted by using RevMan 5.4 software. RESULTS A total of 9 RCTs were included, involving 1 882 patients. The results of meta-analysis showed that: total response rate [OR=1.94,95%CI(1.45,2.58),P<0.000 01], cure rate [OR=2.27,95%CI(1.33,3.86),P=0.003] and remission rate [OR=1.81,95%CI(1.28, 2.55), P=0.000 7] of trial group were significantly higher than control group; there was no significant difference in the incidence of adverse drug events, diarrhea, nasopharyngitis, upper respiratory tract infection and alkaline phosphatase elevation between two groups (P>0.05). The results of subgroup analysis showed that cure rate of trial group was significantly higher than control group at 2 weeks of treatment (P<0.05); at 4 and 8 weeks of treatment, there was no significant difference in the cure rate between two groups (P>0.05). There was no statistically significant difference in the cure rate between two groups at 2, 4 and 8 weeks of treatment among the patients with Los Angeles grade A/B (P>0.05); among the patients with Los Angeles grade C/D, the cure rate of patients in the trial group was significantly higher than control group at 2, 4 and 8 weeks of treatment (P<0.05). The results of sensitivity analysis and publication bias analysis showed that the results of this study were robust and the possibility of publication bias was small. CONCLUSIONS Vonoprazan has a considerable effectiveness and safety in the treatment of gastroesophageal reflux disease.

The extraordinary advantages associated with mRNA vaccines, including their high efficiency, relatively low severity of side effects, and ease of manufacture, have enabled them to be a promising immunotherapy approach against various infectious diseases and cancers. Nevertheless, most mRNA delivery carriers have many disadvantages, such as high toxicity, poor biocompatibility, and low efficiency in vivo, which have hindered the widespread use of mRNA vaccines. To further characterize and solve these problems and develop a new type of safe and efficient mRNA delivery carrier, a negatively charged SA@DOTAP-mRNA nanovaccine was prepared in this study by coating DOTAP-mRNA with the natural anionic polymer sodium alginate (SA). Intriguingly, the transfection efficiency of SA@DOTAP-mRNA was significantly higher than that of DOTAP-mRNA, which was not due to the increase in cellular uptake but was associated with changes in the endocytosis pathway and the strong lysosome escape ability of SA@DOTAP-mRNA. In addition, we found that SA significantly increased the expression of LUC-mRNA in mice and achieved certain spleen targeting. Finally, we confirmed that SA@DOTAP-mRNA had a stronger antigen-presenting ability in E. G7-OVA tumor-bearing mice, dramatically inducing the proliferation of OVA-specific CLTs and ameliorating the antitumor effect. Therefore, we firmly believe that the coating strategy applied to cationic liposome/mRNA complexes is of potential research value in the field of mRNA delivery and has promising clinical application prospects.
