Objective To investigate the expression level and clinical application value of circular RNA hsa_circ_0001766 in gastric cancer(GC)tissues and serum of patients with GC.Methods The PCR amplification products from GES-1 cells of normal gastric mucosa were analyzed for the cyclic sites of hsa_circ_0001766 by the Sanger sequencing technique.The expression levels of hsa_circ_0001766 in GES-1 cells treated or untreated with RNase R(RNase R)were detected by real-time fluorescence quantitative PCR(qRT-PCR).The expression levels of hsa_circ_0001766 in GC and adjacent tissues of 73 GC patients and serum samples of 34 GC patients were also detected by qRT-PCR.The receiver operating characteristics(ROC)curve was used to evaluate the clinical diag-nostic value of hsa_circ_0001766 in GC.The correlations between hsa_circ_0001766 and clinicopathological parameters in GC patients were also analyzed.Results There was cyclic sites in hsa_circ_0001766 and RNase R had no significant impact on the expression lev-el of hsa_circ_0001766 in GES-1 cells(t=1.678,P=0.169).Compared with adjacent tissues,the expression levels of hsa_circ_0001766 in GC tissues were significantly up-regulated(U=1 360,P<0.001).Compared with healthy controls,the expres-sion levels of hsa_circ_0001766 in serum of GC patients were significantly up-regulated(U=375,P<0.001).The area under the ROC curve(AUCROC),sensitivity,and specificity of hsa_circ_0001766 in GC tissues for diagnosing GC were 0.759(95％CI:0.682-0.837,P<0.000 1),79.45％,and 68.49％,respectively.The AUCROC,sensitivity,and specificity of serum hsa_circ_0001766 in diagnosing GC were 0.773(95％CI:0.662-0.884,P<0.000 1),73.53％,and 72.12％,respectively.The expression levels of hsa_circ_0001766 in GC tissues were correlated with lymph node metastasis(x2=5.509,P=0.019)and TNM staging(x2=5.161,P=0.023).The 3-year survival rate of GC patients with high expression of hsa_circ_0001766 in GC tissues was significantly lower than that with low ex-pression(x2=3.700,P=0.037).Conclusion The hsa_circ_0001766 in GC tissues and serum of GC patients is highly expressed,and its change in the expression level is of great significance for the diagnosis and prognostic evaluation of GC patients.

Objective To investigate the value of adjusting antiplatelet treatment regimens guided by thromboelastography(TEG)in predicting cerebral ischemic events after stent-assisted embolization of intracranial aneurysms.Methods This study retrospectively and consecutively enrolled patients with intracranial aneurysms who underwent stent-assisted coil embolization admitted to the Department of Neurosurgery of the General Hospital of Eastern Theater Command,from March 2022 to May 2024.Baseline and clinical data of the patients,including gender,age,hypertension,diabetes,dyslipidemia,smoking history,drinking history,and intraoperative use of tirofiban were collected.Antiplatelet therapy(conventional dose aspirin[100 mg once daily]+clopidogrel[75 mg once daily])was initiated immediately after the diagnosis of intracranial aneurysm,and TEG was performed 3 days later.According to the platelet inhibition rate in TEG parameters(platelet inhibition rate induced by arachidonic acid[AA]pathway[AA inhibition rate]or adenosine diphosphate[ADP]pathway[ADP inhibition rate],AA inhibition rate ≥ 50％indicated aspirin effectiveness,AA inhibition rate＜50％indicated aspirin resistance;ADP inhibition rate ≥ 30％indicated clopidogrel effectiveness,ADP inhibition rate＜30％indicated clopidogrel resistance),the patients were divided into the control group(TEG test results met the criteria,i.e.,AA inhibition rate ≥ 50％and ADP inhibition rate ≥ 30％),the conventional dual antiplatelet therapy group(TEG test results did not meet the criteria but were not adjusted for antiplatelet therapy,i.e.,AA inhibition rate＜50％and/or ADP inhibition rate＜30％,but with complex aneurysm morphology[such as irregular shape,daughter sac formation]or high bleeding risk,continuing conventional dual antiplatelet therapy),and the intensified group(TEG test results did not meet the criteria and the antiplatelet therapy regimen was adjusted,i.e.,AA inhibition rate＜50％and/or ADP inhibition rate＜30％,adjusting the antiplatelet therapy regimen).All patients underwent stent-assisted coil embolization after TEG testing.From 0 to 3 months after the operation,all three groups maintained the above antiplatelet therapy.At 3 months after the operation,routine head MRI,CT and other examinations were performed.If no cerebral ischemic events occurred and the imaging results were satisfactory(good stent position,no aneurysm occlusion residual or slight residual at the neck[neck width of the aneurysm 2mm]),the treatment could be adjusted to single antiplatelet therapy(aspirin 100 mg once daily).If a patient experienced a cerebral ischemic event during the follow-up period,regardless of the stage after the operation,dual antiplatelet therapy(aspirin[100mg once daily]+clopidogrel[75 mg once daily])was immediately restarted or maintained and continued for at least 6 months.The primary endpoint was intraoperative and 6-months postoperative cerebral ischemic events(including DSA-confirmed intraoperative acute thrombosis and infarction foci confirmed by head CT or MRI).Baseline and clinical data of the three groups were compared.All patients were divided into groups with ischemic stroke event and without according to the primary endpoint,univariate Logistic regression analysis was then performed on both groups.Variables with P＜0.1 in the univariate Logistic regression analysis were included in the multivariate Logistic regression analysis to explore the influencing factors of cerebral ischemic events after stent-assisted coil embolization for intracranial aneurysms.Results A total of 499 patients were included,including 178 males and 321 females,with a median age of 59(53,68)years.Among them,there were 341 patients in the control group,42 in the conventional dual antiplatelet therapy group,and 116 in the intensified group.There were 47 cases of cerebral ischemic events and 452 cases without cerebral ischemic events.There was a statistically significant difference in the intraoperative use rate of tirofiban across the control group,the conventional dual antiplatelet therapy group,and the intensified group(20.2％[69/341]vs.26.2％[11/42]vs.42.2％[49/116],P＜0.01);no statistically significant differences were observed among the three groups in terms of age,gender composition,the proportion of patients with hypertension,diabetes,dyslipidemia,smoking history,drinking history,and the incidence of cerebral ischemic events(all P＞0.05).The results of multivariate Logistic regression analysis showed that hypertension(OR,2.924,95％CI 1.416-6.037,P=0.004)and intraoperative use of tirofiban(OR,3.638,95％CI 1.892-6.996,P＜0.01)were independent risk factors for intraoperative and 6-months postoperative cerebral ischemic events after stent-assisted coil embolization in patients with intracranial aneurysms.In comparison with the control group,the intensified group has reduced the risk of cerebral ischemic events(OR,0.238,95％CI 0.088-0.646,P=0.005),while there was no statistically significant difference between the conventional dual antiplatelet therapy group and the control group(OR,0.521,95％CI 0.149-1.826,P=0.308).Conclusions This study demonstrates that adjusting the antiplatelet therapy regimens in patients with intracranial aneurysms who did not meet the platelet inhibition rate based on TEG results can significantly reduce the risk of intraoperative and 6-months postoperative cerebral ischemic events.These finding may require validation through further,large-scaled,prospective studies.

Objective:To investigate the status quo of occult hepatitis B virus infection (OBI) among blood donors in certain region and to explore the characteristics of amino acid variation between antibody to hepatitis B core antigen (HBcAb) and S region.Methods:The qualified blood samples from January 2019 to December 2022 were collected, and the OBI samples were screened by ELISA and HBV DNA. The OBI samples were quantitatively detected by HBcAb and HBV DNA and analyzed by HBV S region sequencing.Results:A total of 126 OBI positive samples were detected out of 188933 samples, the detection rate was 0.07%, and there was no significant difference in the detection rate of OBI between gender and blood donation times ( P>0.05). The highest OBI detection rate was found in 46-55 years old group (0.15%), other education group (0.35%) and occupational workers group (0.13%). The total detection rate of HBcAb (+ ) in 126 OBI samples was 90.48%. As the S/CO value of HBcAb (+ ) increased, the positive detection rate of HBV DNA also increased, and the correlation coefficient between HBcAb (+ ) and the quantitative value of HBV DNA was 0.782. The proportion of HBV B genotype in OBI blood donors was the highest (73.08%). A total of 15 OBI-related mutation sites were found, and there was no statistically significant difference among the mutation sites. Conclusions:OBI exists in blood donors in certain region, and HBcAb (+ ) is moderately positively correlated with the quantitative value of HBV DNA. HBV infection in OBI blood donors is mainly type B.

Objective:To compare the clinical efficacies of gasless transoral vestibular robotic surgery and open surgery for the treatment of thyroglossal duct cysts.Methods:A retrospective analysis was conducted on patients with thyroglossal duct cysts who underwent surgical treatment in the Department of Otolaryngology at Sun Yat-sen Memorial Hospital, Sun Yat-sen University from August 2020 to October 2023. According to the differences in surgical methods, patients were divided into a robotic surgery group and an open surgery group. Statistical analysis was conducted on demographic data, surgical time, bleeding volumes, drainage volumes, postoperative complications, scar conditions, postoperative aesthetic scores, and recurrence rates of the two groups of patients. For normally distributed measurement data, inter-group comparison was done via independent-sample t-test. For non-normally distributed data, Mann-Whitney U test was applied. Comparisons of composition ratios or rates were performed using the χ2 test or Fisher′s exact probability method. Results:A total of 44 patients with thyroglossal duct cysts who met the inclusion and exclusion criteria were included, including 22 males and 22 females, aged from 3 to 73 years old. Both the robotic surgery group and the open surgery group had respectively 22 cases. The maximum diameter of tumors of the open surgery group was 3.45(2.50, 4.00) cm, while the robotic surgery group measured 2.50 (2.10, 3.20) cm, with the open group demonstrating significantly larger tumor dimensions compared to the robotic group ( Z=-2.329, P<0.05). Compared to the open surgery group, the robotic surgery group showed significantly more surgical time [105.00 (95.00, 135.00) min vs. 65.00(58.75, 76.25) min, Z=-5.377, P<0.05], postoperative hospitalization time [4.00 (3.75, 5.00) days vs. 3.00(2.00, 4.00) days, Z=-3.202, P<0.05] and bleeding volume [20.00 (10.00, 20.00) ml vs. 5.00 (5.00, 10.00) ml, Z=-4.769, P<0.05], but had less scar length [0 cm vs. 4.00 (2.00, 5.00) cm, Z=-6.097, P<0.05] and better postoperative cosmetic satisfaction [10.00 (10.00, 10.00) vs. 8.00 (6.75, 8.00), Z=-5.221, P<0.05]. With follow-up of 10.0-48.0 months, both the robotic surgery group and the open surgery group showed no recurrence. There was no significant difference in the follow-up time between the two groups ( Z=-0.224, P=0.823). Conclusion:Gasless transoral vestibular robotic surgery is safe and feasible for the treatment of thyroglossal duct cysts, with efficacy comparable to traditional surgery, which can provide a new option for the treatment of thyroglossal duct cysts.

Objective:To compare the efficacy of gasless robotic surgery via transaxillary approach and combined axillary-retroauricular approach for unilateral N1b PTC, and to explore the safety and effectiveness of gasless robotic surgery via transaxillary approach for unilateral N1b PTC. Methods:Unilateral N1b PTC patients who underwent surgery in the Department of Otolaryngology, Sun Yat Sen Memorial Hospital, Sun Yat sen University between July 2016 and December 2024 were included and analyzed. According to the inclusion and exclusion criteria and the differences of surgical approaches, the patients were divided into the transaxillary approach（TA） group and the combined axillary-retroauricular approach（TARA） group. The demographic data, operation time, intraoperative blood loss, postoperative drainage volume, postoperative complications, shoulder function evaluation, postoperative visual analogue scale（VAS） of neck aesthetics and recurrence of the two groups were statistically analyzed. Results:A total of 88 patients undergoing gasless robotic surgery were included in this study, including 23 cases in the TA group and 65 cases in the TARA group. The proportion of males in the TA group was significantly higher than that in the TARA group（56.5% vs 21.5%, χ²=9.776, P=0.002）. The total operation time in the TA group was significantly lower than that in the TARA Group（180.00[155.00, 220.00]min vs 220.00[177.50, 272.50]min, z=-2.775, P=0.006）, and the postoperative blood loss in the TA group was significantly lower than that in the TARA Group（30.00[20.00, 50.00]ml vs 50.00[30.00, 60.00]ml, Z=-2.127, P=0.033）. The proportion of area Ⅱ-Ⅴ in the TA group and the TARA group was 87.0% and 70.8%, respectively, and there was no significant difference between the two groups（P>0.05）. There was no significant difference in lateral cervical lymph node dissection and central lymph node dissection between the two groups（P>0.05）. During the follow-up period, no recurrence was found in the two groups, and there was no significant difference in the incidence of complications between the two groups（P>0.05）. According to the stratification of dynamic recurrence risk assessment, it can be seen that the proportion of curative effect satisfaction in the TA group was as high as 95.7%, and that in the TARA group was as high as 81.5%, with no significant difference between the two groups. There was no significant difference in VAS score of neck, Constant Shoulder Score and NDⅡ scale between the two groups（P>0.05）. Conclusion:Gasless robotic surgery via transaxillary approach for unilateral N1b PTC is safe and feasible, and the amount postoperative lymph node acquisition is equivalent to that of combined axillary-retroauricular approach, which can provide a new choice for the treatment of unilateral N1b PTC patients.

Kupffer cells (KCs), as residents and sentinels of the liver, are involved in the formation of hepatic fibrosis (HF). However, the biological functions of circular RNAs (circRNAs) in KCs to HF have not been determined. In this study, the expression levels of circRNAs, microRNAs, and messenger RNAs (mRNAs) in KCs from a mouse model of HF mice were investigated using microarray and circRNA-Seq analyses. circDcbld2 was identified as a candidate circRNA in HF, as evidenced by its up-regulation in KCs. Silver staining and mass spectrometry showed that Wtap and Igf2bp2 bind to cirDcbld2. The suppression of circDcbld2 expression decreased the KC inflammatory response and oxidative stress and inhibited hepatic stellate cell (HSCs) activation, attenuating mouse liver fibrogenesis. Mechanistically, Wtap mediated the N ⁶-methyladenosine (m6A) methylation of circDcbld2, and Igf2bp2 recognized m6A-modified circDcbld2 and increased its stability. circDcbld2 contributes to the occurrence of HF by binding miR-144-3p/Et-1 to regulate the inflammatory response and oxidative stress. These findings indicate that circDcbld2 functions via the m6A/circDcbld2/miR-144-3p/Et-1 axis and may act as a potential biomarker for HF treatment.

Chronic atrophic gastritis （CAG），as a key stage of precancerous lesions of gastric cancer，has an increasing incidence year by year，and it can gradually develop into gastric invasive cancer and mucosal cancer. At present，the main treatment focuses on the eradication of Helicobacter pylori （Hp），drug therapy， and pathological follow-up by gastroscopy，which can alleviate some symptoms，but it is difficult to curb the pathological progress，and the recurrence rate is high. Phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway is involved in the regulation of cell growth，differentiation，proliferation，apoptosis，autophagy， and other responses，and abnormal activation of this pathway can promote the progression of precancerous lesions of CAG. Traditional Chinese medicine is effective in the treatment of precancerous lesions of CAG through multi-component and multi-target comprehensive regulation. By regulating the PI3K/Akt pathway，the active ingredients and compounds of traditional Chinese medicine play therapeutic roles，such as inhibiting inflammation，glycolysis，angiogenesis， and epithelium-mesenchymal transformation，promoting autophagy，and regulating the balance of cell proliferation and apoptosis. This paper systematically reviewed the mechanism of traditional Chinese medicine intervention in the PI3K/Akt pathway in the treatment of precancerous lesions of CAG，so as to provide references for further understanding of the pathogenesis of precancerous lesions of CAG and search for potential therapeutic targets，and it provided new ideas for further research and drug development of precancerous lesions of CAG.
