AIM: To evaluate the diagnostic value of serum Th1-type cytokine levels and extraocular muscle-related parameters in thyroid-associated ophthalmopathy(TAO).METHODS: A retrospective study was conducted on 45 patients diagnosed with TAO in our hospital from January 2023 to December 2024, and 20 normal volunteers during the same period as controls. Venous blood samples of the patients were collected to detect the concentrations of Th1-type cytokines [interferon-γ(IFN-γ), tumor necrosis factor-α(TNF-α), interleukin-2(IL-2), and interleukin-12(IL-12)] in the serum. Additionally, the end diastolic velocity(Ved), velocity maximum(Vmax), resistance index(RI)of the central retinal artery, as well as the thickness and left-right diameter of the medial rectus muscle were measured. Logistic regression model was used to analyze the risk factors of TAO, and receiver operating characteristic curve(ROC)was adopted to evaluate the diagnostic efficacy of each index for the occurrence of TAO.RESULTS: The general information of the two groups was comparable. Compared with the normal control group, the serum concentrations of IFN-γ and TNF-α in TAO patients were significantly increased, Ved and Vmax were lower than those in the control group, and RI and the thickness of the medial rectus muscle were higher than those in the control group(all P<0.05). Logistic regression analysis showed that serum IFN-γ concentration, Ved, Vmax, and the thickness of the medial rectus muscle were all risk factors for TAO. ROC curve analysis indicated that the AUCs of serum IFN-γ concentration, Ved, Vmax, and the thickness of the medial rectus muscle for the diagnostic efficacy of TAO were 0.756, 0.769, 0.732, and 0.642, respectively. The combined detection of IFN-γ, Ved, Vmax, and the thickness of the medial rectus muscle had an AUC of 0.840 and a Youden index of 0.59, which was superior to the detection of a single indicator.CONCLUSION: The levels of serum Th1-type cytokines and extraocular muscle-related ultrasound indicators have certain value in the diagnosis of TAO. The combination of IFN-γ, Ved, Vmax, and the thickness of the medial rectus muscle has better diagnosis efficiency in TAO, which can provide a certain reference for the early diagnosis of TAO.

Objective The aim of this study was to investigate the impact and mechanisms of emodin on oxidative stress response in lipopolysaccharide(LPS)-induced murine mononuclear macrophages(RAW264.7).Methods Involved the use of LPS,RAW264.7 cells,and emodin.Experimental groups included a control group,LPS(1 μg/mL)group,and LPS(1 μg/mL)+emodin(15 μmmol/L)pretreatment group.Aldehyde malondialdehyde(MDA)content,intracellular reactive oxygen species(ROS)levels,and silent information regulator 2(Sirt2)expression were evaluated at 6,12,and 18 hours after LPS exposure.Additionally,RAW264.7 cells were pretreated with Sirt2 inhibitor AGK2(20 μmol/L)followed by LPS stimulation,and the above-mentioned parameters were assessed at 6 hours.Results Compared to the control group,MDA content,ROS levels,Sirt2 mRNA,and protein expression in RAW264.7 cells in the LPS group increased at all time points(all P<0.05).At 6 and 18 hours,MDA content and ROS levels in RAW264.7 cells in the LPS+emodin group decreased significantly(all P<0.05),while at 12 hours,ROS levels were lower in the LPS group compared to the LPS+emodin group(P<0.05).Sirt2 mRNA and protein levels significantly increased at all time points(all P<0.05)compared to the LPS group.In the LPS+emodin+AGK2 group,Sirt2 mRNA and protein levels decreased,and MDA content and ROS levels increased compared to the LPS+emodin group(all P<0.05).Conclusion LPS-induced oxidative stress in RAW264.7 cells and emodin attenuate LPS-induced oxidative stress in RAW264.7 cells through Sirt2.

【Objective】 To explore the effect and mechanism of Fasudil in the treatment of experimental autoimmune myocarditis (EAM) in mice so as to provide a theoretical basis for the clinical use of Fasudil in treating myocarditis. 【Methods】 Balb/c male mice were used as the research objects, and the EAM mice model was constructed using MyHC-α614-629 polypeptide. Mononuclear cells were isolated and cultured to detect the number of mononuclear cells in mouse spleen. Inflammation infiltration, fibrosis and IL-6 expression in mouse myocardial tissue were detected by HE staining, Masson staining and immunohistochemistry, respectively. The protein expressions of Notch1 and IL-6 were detected by Western blotting. qRT-PCR was used to detect the expressions of pro-inflammatory factors (IL-1α, IL-1β and IL-6) as well as key genes of TLRs and NOTCH signaling pathway. 【Results】 EAM mice showed increased HW, decreased BW, increased HW/e-BW, and increased inflammatory infiltration and fibrosis in myocardial tissue. The above-mentioned symptoms or pathological features were improved in EAM mice treated with Fasudil. The analysis showed that the pro-inflammatory factors IL-1α, IL-1β and IL-6 in the myocardial tissue of EAM mice were significantly increased, but only the expression of IL-6 was statistically different after Fasudil treatment compared with the control group. In addition, TLRs signaling pathway might also play an important role in the EAM mice treated with Fasudil. The expressions of IL-6 and Notch1 were consistent, and the expressions of the key genes of NOTCH signaling pathway (Notch1, Hes1 and Jag2) were down-regulated after Fasudil treatment. 【Conclusion】 Fasudil exerts a protective effect on down-regulation of IL-6 expression by inhibiting the NOTCH signaling pathway in EAM mice.

Objective:To evaluate the functional and anatomical outcomes of autologous single retinal pigment epithelium (RPE) transplantation for severe obsolete submacular hemorrhage (SMH) in late age-related macular degeneration (AMD).Methods:A retrospective clinical study. From January 2012 to December 2015, 11 patients with AMD (11 eyes) with obsolete SMH who were diagnosed and treated by pars plana vitrectomy (PPV) combined with autologous RPE transplantation at the Department of Ophthalmology, Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were included. Among them, there were 9 eyes in 9 males and 2 eyes in 2 females. All the eyes underwent the examinations of best corrected visual acuity (BCVA) and optical coherence tomography; 4 eyes underwent macular fixation function (MAIA) at the same time. The BCVA examination was carried out using the international standard visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. All eyes were treated with PPV combined with autologous single-layer RPE transplantation or autologous RPE-choroidal full-thickness transplantation, and were divided into S group and C group, with 5 and 6 eyes respectively. The differences of age ( t=-0.363), gender composition ratio ( χ2=0.549), course and thickness of SMH ( t=0.118, 0.231), average times of anti-vascular endothelial growth factor drug treatments ( t=0.129), times of PPV ( t=-0.452) between the two groups were not statistically significant ( P>0.05). The follow-up period was 6-40 months after the operation, and the BCVA, MAIA, graft status and complications of the eyes after the operation were observed. The comparison of continuous variables between groups was performed by independent-sample t test; the comparison of categorical variables was performed by χ2 test. Results:At the last follow-up, the average logMAR BCVA of the eyes in group S and C were 1.62±0.34 and 1.03±0.20, respectively; group C was better than group S, however, the difference was not statistically significant ( t=1.532, P=0.160). There were 4 eyes (80%, 4/5) and 6 eyes (100%, 6/6) in S group and C group with BCVA better than preoperative, the difference was no statistical significance ( χ2=0.677, P=0.895). There were 2 (40%, 2/5) and 3 (50%, 3/6) eyes with logMAR BCVA better than 1.0 in S group and C group, and the difference was not statistically significant ( χ2=0.572, P=0.423). After the operation, 6 eyes of grafts were in good condition and 5 eyes were in poor condition; the BCVA of grafts in good condition was significantly higher than that of poor condition, the difference was statistically significant ( t=4.894, P=0.001). Among the 4 eyes that underwent MAIA examination, 2 eyes were unstable and diffusely fixed on the graft; the fixation point was located at the normal retina adjacent to the graft area in 2 eyes. Secondary subretinal hemorrhage occurred in 3 eyes after the operation; the intraocular pressure was high in 1 eye after the operation. During the follow-up period, no intraocular infection, secondary retinal detachment, recurrent choroidal neovascularization or low intraocular pressure occurred in all eyes. Conclusions:Both autologous single-layer RPE transplantation and autologous RPE-choroidal full-thickness transplantation can help stabilize or even improve the visual function of eyes with severe SMH secondary to advanced AMD. The visual acuity after surgery is closely related to the state of the graft.

Objective:To understand the overall satisfaction rate with vaccination services in parents of children, and the impact of additional time consumed for vaccination service on overall satisfaction rate.Methods:From December 2019 to January 2020, a total of 3 178 parents of 0-3 years old children were investigated to collect the information about their basic characteristics, additional time spent for vaccination service and overall satisfaction through questionnaires. Binary logistic regression model and restricted cubic spline model were used to evaluate the impact of additional time spend on the overall satisfaction rate.Results:The overall satisfaction rate of parents with vaccination services was 92.32%. The median time for parents to move from home to vaccination clinic was 10.00 (10.00, 20.00) minutes, the median waiting time to make an appointment was 10.00 (5.00, 15.00) minutes, the median waiting time for vaccination was 5.00 (3.00, 10.00) minutes, and the median total additional time spent was 30.00 (20.00, 45.00) minutes. The binary logistic regression analysis showed that after adjusting the relevant factors, the main factors affecting the overall satisfaction rate were the waiting time for making an appointment (the 4- minutes group vs. 8- minutes group: OR=1.863, 95% CI: 1.307-2.657), waiting time for vaccination (the <4 minutes group vs. 8- minutes group: OR=1.529, 95% CI: 1.102-2.120; the 4- minutes group vs. 8- minutes group: OR=1.534, 95% CI: 1.104-2.130), total additional time spent (the 15- minutes group vs. 30- minutes group: OR=1.470, 95% CI: 1.094-1.976). Restricted cubic spline analysis showed that the waiting time for making an appointment (non-linear: χ2=13.18, P=0.001), the waiting time for vaccination (non-linear: χ2=13.50, P=0.001), and the total additional time consumed (non-linear: χ2=9.38, P=0.009) showed a non-linear inverted "V" dose response relationship to the overall satisfaction of vaccination services. Conclusions:The waiting time for parents to make an appointment, the waiting time for vaccination and the total additional time spent for receiving vaccination services affected the overall satisfaction rate of the vaccination services. And the waiting time for making an appointment was the most important factor, and it is necessary to shorten the waiting time for appointment. It is suggested that the vaccination clinic should make use of information technology (such as WeChat public account, APP) to make accurate appointments, make appointments to the time period to control the number of people within time period.

Objective:To understand the time for observation and related factors in the clinics after vaccination among children's parents.Methods:From December 2019 to January 2020, parents of children aged 0-3 years were recruited by multiple-stage sampling from 34 vaccination clinics in 12 districts and counties in 6 provinces (Shandong, Guangdong, Henan, Sichuan, Inner Mongolia, and Liaoning). A questionnaire survey on the time of observation after vaccination was conducted. A multivariate logistic regression model was used to analyze the related factors of parental observation time after vaccination.Results:A total of 3 292 parents of 0-3 year's old children were selected, and 3 178 parents were finally included in the analysis. 87.85%(2 792/3 178) of the parents reported that the observation time after vaccination at clinics was ≥30 minutes. Multivariate logistic regression analysis showed that, after adjusting for the regions, the main factors affecting the observation time at clinics after vaccination among parents appeared as observation time informed by physicians at the clinic appeared ≥30 minutes ( OR=31.622, 95% CI: 19.847-50.384), parents were medical personnel ( OR=2.779, 95% CI: 1.505-5.133), parents being volunteers working on vaccination-related publicity and education activities ( OR=1.986, 95% CI: 1.438-2.743), parents aged 35 years old or above ( OR=1.900, 95% CI: 1.215-2.971), being parents of the first child ( OR=1.663, 95% CI: 1.282-2.156), per capita annual income of the family as 8 000- Yuan ( OR=1.646, 95% CI: 1.168-2.319), children aged 0-12 months old ( OR=1.646, 95% CI: 1.203-2.252) or 13-24 months old ( OR=1.506, 95% CI: 1.064-2.133), obedient to physicians' advice at the clinic ( OR=1.481, 95% CI: 1.067-2.055). Conclusions:The proportions of parents observed for ≥30 minutes at the clinics of vaccination were high. When the information was from the physicians at the vaccination clinic, the observation time was the most critical factor for parents to observe at clinics as required.

To investigate the effects of ()infection on autonomic nervous function and calcitonin gene-related peptide in patients with functional dyspepsia(FD). Thirty-one patients with FD matching Rome Ⅳ criteria were included and divided into -positive group and -negative group.All patients were evaluated by Symptom Index of Dyspepsia(SID),Nepean Dyspepsia Index(NDI),and Hospital Anxiety and Depression Scale(HADS).Their heart rate variability(HRV)and calcitonin gene-related peptide(CGRP)level were also measured. There were no significant differences in SID(=-0.858, =0.858),NDI(=-1.464, =0.143),and Hospital Depression Scale score(=0.699, =0.485).However,the Hospital Anxiety Scale score was significantly higher in -positive group than the -negative group(=-2.470, =0.014).The level of CGRP in -positive group[(0.999±0.274)ng/ml]was significantly higher than that in the -negative group[(0.812±0.172)ng/ml;=2.238, =0.033].HRV data showed no significant difference between these two groups at very low frequency(=-1.210, =0.236),low frequency(LF)(=0.419, =0.678),high frequency(HF)(=0.612, =0.546),LF/HF(=-0.882, =0.399),and total power(=-0.963, =0.344). In FD patients,patients with -positive FD patients have higher depression and CGRP levels than those without infection,although their dyspepsia symptoms and HRV show no notable changes.

Objective To compare the clinical effect between small incision surgery and traditional resection for thyroid adenoma. Methods 60 patients with thyroid adenoma were divided into two groups according to different surgical methods. 30 patients in the observation group underwent small incision resection, and 30 patients in the control group underwent conventional thyroid tumor resection. The postoperative surgical results, the intraoperative blood loss, operation time, hospital stay and postoperative complications were compared between the two groups. Results The intraoperative blood loss of the observation group was (19.15±8.30) mL, which was significantly than that of the control group. The operation time of the observation group was (78.73±12.61) min, which was significantly than that of the control group.The hospitalization time of the observation group was (3.74±1.05) d, which was significantly shorter than that in the con trol group, and the difference was significant (P<0.05). After operation, the total effective rate of the observation group was significantly higher than that of the control group, and the difference was significant (P<0.05). The postoperative complication rate of the observation group was significantly lower than that of the control group. There was significant difference between the two groups (3.3％ vs 16.7％, P<0.05). Conclusion Small incision surgery is more effective than traditional resection for thyroid adenoma. It has the advantages of small incision, less bleeding, less complications, and quick recovery after surgery.It is worthy of widespread application and application.
