Objective This study reveals the potential mechanism of electroacupuncture in alleviating the inflamma-tory injury of sensory nerves and alleviating the abnormal sensation on the ocular surface in type 2 diabetes rats with dry eye.Methods Healthy male SD rats were induced to establish type 2 diabetes dry eye rat model.Model rats were ran-domly divided into model group,electroacupuncture group,sham-acupuncture group,and fluorometholone group in the 12th week of the experiment.The blank group was established as well,and each group was intervened for 2 weeks.The corneal fluorescein sodium staining(FL),break-up time(BUT),phenol red thread test(PRT),corneal mechanical per-ception threshold(CTT)and blink frequency were measured in each group of rats.After sampling,the expression of neu-ronal injury markers,neuron specific enolase(NSE),neurofilament light chain protein Nf Light(NF-L),phosphorylated microtubule associated protein(Phospho-TAU),as well as inflammatory factors of cysteine protease-1(Caspase-1),inter-leukin-18(IL-18),and interleukin-1β(IL-1β),were observed in the trigeminal ganglion(TG)and spinal cord caudate nu-cleus(SpVc)of each group of rats.Results At the end of the 14th week,compared with the blank group,the FL of the model group,electroacupuncture group,sham-acupuncture group,and fluorometholone group significantly increased,while PRT and BUT significantly decreased.Moreover,the CTT and blink frequency of the model group,sham-acupuncture group,and fluorometholone group significantly decreased(all P＜0.01).Compared with the model group,the electroacu-puncture group and the fluorometholone group showed a decrease in FL,as well as an increase in BUT,PRT,CTT,and blink frequency,with statistically significant differences(all P＜0.05).Compared with the electroacupuncture group,the sham-acupuncture group showed significantly higher FL along with significantly lower values in BUT,PRT,CTT,and blink frequency(all P＜0.05),while the fluorometholone group exhibited decreased FL,PRT,CTT,and blink frequency but in-creased BUT(all P＜0.05).Compared to the sham-acupuncture group,the fluorometholone group exhibited significantly lower FL,but higher BUT and PRT(all P＜0.01).In TG and Sp Vc,compared with the blank group,the expression of NSE,NF-L and Phospho-TAU increased in the model group and the sham-acupuncture group(all P＜0.05);compared with the model group,the expression of NSE,NF-L and Phospho-TAU significantly reduced in the electroacupuncture group(P＜0.01);compared with the electroacupuncture group,the expression of NSE,NF-L and Phospho-TAU increased in the electroacupuncture group and the expression of Phospho-TAU in the sham-acupuncture group also increased(P＜0.05);compared with the sham-acupuncture group,the expression of Phospho-TAU or NF-L significantly reduced in the fluoro-metholone group(all P＜0.05).The Western Blot results indicate that compared with the blank group,the protein expres-sion of Caspase-1,IL-1β,and IL-18 in TG and SpVc of the model group increased;moreover,the expression of Caspase-1 and IL-18 proteins in the sham-acupuncture group also increased(all P＜0.05).Compared with the model group,the ex-pression of Caspase-1,IL-1β,and IL-18 proteins in TG and SpVc reduced in the electroacupuncture group and the fluoro-metholone group,and the expression of IL-1 β proteins in TG and SpVc also reduced in the sham-acupuncture group(all P＜0.05).Compared with the electroacupuncture group,the expression of Caspase-1,IL-1 β,and IL-18 proteins in TG and SpVc increased in the sham-acupuncture group(all P＜0.05).Compared with the sham-acupuncture group,the expression of Caspase-1,IL-1 β,and IL-18 proteins in TG and SpVc reduced in the fluorometholone group(all P＜0.05).Conclusion Electroacupuncture can effectively alleviate the abnormal ocular surface sensation of type 2 diabetes dry eye rats by alleviating the neuroinflammatory injury in TG and SpVc.

Purpose To analyze and discuss the clinicopathological,molecular pathological characteristics,as well as diagnostic and prognostic features of pleomorphic xanthoastrocytoma(PXA)according to the new WHO classifi-cation.Methods 79 cases of PXA were collected to analyze their pathological and clinical data.Immunohistochemis-try using the EnVision method was employed to detect the expression of CD34,ATRX,Rb,Olig-2,H3K27M,H3K27me3,IDH1 R132H,BRAF VE1 and Ki67.Sanger sequencing was used to detect mutations in H3F3A and IDH1/2.Fluorescence quantitative PCR was used to detect the BRAF V600E mutation and TERT promoter region al-terations.Fluorescence in situ hybridization(FISH)was used to detect CDKN2A and EGFR alterations.The relation-ship between clinical,pathological,molecular genetics data,and prognosis was analyzed.Results The patients'ages ranged from 9 to 69 years,with an average age of 36.4 years.Most tumors were located in the temporal lobe,frontal lobe and parietal lobe.Among the 79 cases,42 were classified as grade 2 PXA and 37 as grade 3 PXA.The tumor cells exhibited pleomorphic changes,with perivascular lymphocytic sheaths and eosinophilic bodies frequently ob-served.Grade 3 PXA exhibited more mitotic figures(average of 11.8/10 HPF),and was usually accompanied by nec-rosis,focal marginal infiltration and microvascular proliferation.Immunohistochemistry and molecular characteristics revealed frequent positivity for CD34,BRAF V600E mutation(68.1％),and CDKN2A homozygous deletion(36.8％)in PXA.Some cases showed TERT gene mutation and absent Rb expression.Univariate survival analysis in-dicated that necrosis,focal marginal infiltration,and CNS WHO grade were related to overall survival,while focal infil-tration and CNS WHO grade were the independent risk factors.Conclusion The prognosis of CNS WHO grade 3 PXA is wrose than that of grade 2 PXA.Accurate diagnosis of PXA requires the combination of the morphological features,immunohistochemical staining,and multiple molecular tests.

Objective:To analyze the human immunodeficiency virus (HIV) screening status and the resulting residual risk (RR) among blood donors across 17 provincial blood centers in China.Methods:This study used a cross-sectional study. Data on HIV infection markers per 100 000 first-time donors (FD) and repeat donors (RD) from January 2015 to December 2024 were extracted from the National Blood Establishment Performance Comparison Information Management System. Questionnaires were used to collect each center′s HIV screening strategy, algorithm, serological test (ST) kit manufacturers, gray-zone setting for ST, and nucleic acid test (NAT) modality, method, and platform. The incidence-window-period model was used to calculate the residual risk for first-time donors (RR FD), repeat donors (RR RD), and total donors (RR TD) at each center. Horizontal and vertical analysis of RR FD, RR RD, and RR TD across centers and years were performed. Results:All 17 centers applied the same HIV screening strategy which was two rounds of ST followed by one round of NAT. Eight of them operated a single screening algorithm, six employed two algorithms and three used three. Eleven centers used both imported and domestic ST kits, five relied on domestic ST kits only, and one used imported ST kits only, while four centers never set a grey zone for ST throughout the decade. For NAT modalities, eight centers adopted both individual nucleic acid test (ID-NAT) and minipool nucleic acid test (MP-NAT), eight used MP-NAT only and one used ID-NAT only. Seven centers combined transcription mediated amplification (TMA) and polymerase chain reaction (PCR), nine used PCR only and one used TMA only, and fourteen centers ran both imported and domestic NAT systems, two used imported systems only and one used a domestic system only. Over the ten-year period, the mean RR FD across the centers ranged from 2.22 to 12.33 per 10 6 person-years, RR RD from 0.83 to 3.29 per 10 6 person-years and RR TD from 1.59 to 9.29 per 10 6 person-years, with center Z4 consistently showing the lowest values for all three metrics and center U4 recording the highest RR FD and RR TD, while center D2 had the highest RR RD. In 2024 compared with 2015, eleven centers achieved a lower RR FD and ten centers achieved lower RR RD and RR TD. The RR FD and RR TD of centers W2 and U4 displayed pronounced fluctuations and an upward trend in recent years. Conclusions:The 17 provincial blood centers maintain consistent HIV screening strategies, while demonstrating variations in screening algorithm, ST kit manufacturers, NAT modalities, methods, and platform. And the RR FD, RR RD, and RR TD differ across centers. Although most centers show declining trend in RR over the ten-year period, some centers exhibite data fluctuations with a rising trend, suggesting potential for further optimization of HIV screening protocols.

Objective:To analyze the impact of lymph node dissection on textbook outcomes (TO) and the prognosis of intrahepatic cholangiocarcinoma (ICC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 376 ICC patients who underwent hepatectomy in 4 medical centers, including Mengchao Hepatobiliary Hospital of Fujian Medical University et al, from December 2011 to December 2017 were collected. There were 242 males and 134 females, aged 57(range, 48-63)years. According to the criteria of TO, patients were classified as two cate-gories, including patients achieving TO and not achieving TO. Measurement data with normal distri-bution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were represented as absolute numbers, and comparison between groups was conducted using the chi-square test, Yates adjusted chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the non-parameter rank sum test. Univariate and multivariate analyses were conducted using the Logistic regression model. The Kaplan-Meier method was used to draw survival curve. Survival analysis was conducted using the Log-rank test. Results:(1) TO situations. Of the 376 ICC patients who underwent hepatectomy, 199 cases achieved TO, including 40 cases with lymph node dissection and 159 cases without lymph node dissection, 177 cases did not achieve TO, including 76 cases with lymph node dissection and 101 cases without lymph node dissection. (2) Influencing factors for TO after hepatectomy of ICC patients. Results of multivariate analysis showed that lymph node dissection, microvascular invasion, nerve invasion and the volume of intraoperative blood loss >800 mL were independent risk factors for achieving TO after hepatec-tomy of ICC patients ( odds ratio=2.22, 2.95, 3.58, 4.09,95% confidence interval as 1.34-3.69, 1.43-6.07, 1.40-9.17, 1.35-12.43, P<0.05). Of the 116 patients with lymph node dissection, 40 cases achieved TO, 103 cases achieved R 0 resection, 38 cases had postoperative complications, 67 cases had delayed hospital stay. The above indicators were 159, 255, 41, 65 of 260 patients without lymph node dissection. There were significant differences in the above indicators between patients with and without lymph node dissection ( χ2=22.90, 15.16, 13.95, 37.78, P<0.05). (3) Follow-up. All the 376 patients were followed up for 19(range, 1-74)months. Of 199 patients achieving TO, the 1-, 2-and 3-year survival rates of 40 patients with lymph node dissection were 54.0%, 36.6% and 26.1%, respectively, versus 67.7%, 42.7% and 34.4% of 159 patients without lymph node dissection, showing no significant difference between them ( χ2=1.89, P>0.05). Of 177 patients not achieving TO, the 1-, 2-and 3-year survival rates of 76 cases with lymph node dissection were 58.9%, 25.7% and 10.3%, respectively, versus 53.0%, 28.5% and 17.2% of 101 cases without lymph node dissection, showing no significant difference between them ( χ2=0.25, P>0.05). Conclusions:Lymph node dissec-tion, microvascular invasion, nerve invasion and the volume of intraoperative blood loss >800 mL are independent risk factors for achieving TO after hepatectomy of ICC patients. Lymph node dissec-tion may increase the postoperative complication rate, prolong the hospital stay and decrease the rate of achieving TO. However, it does not affect the prognosis of patients.

Objective Dry eye is a common complication of diabetes.Electroacupuncture is clinically effective in the treatment of dry eye in diabetes,but its mechanism is still unclear.The aim of this study is to reveal how electroacupuncture regulates Caspase-1 and its downstream IL-1 β and 18,to improve keratitis in type 2 diabetic dry eye rats,thereby alleviating the potential mechanism of ocular surface signs in type 2 diabetic dry eye rats.Methods The model of type 2 diabetic rats with dry eye was established by intraperitoneal injection of 1％streptozotocin,and blank group,model group,electroacupuncture group,sham acupuncture group and fluminolone group were established.Selecting Jingming,Zanzhu,Sizhukong,Taiyang,and Tongziliao for electroacupuncture intervention.Random blood glucose levels,tear film rupture time,corneal fluorescein sodium staining,phenol red cotton thread test,corneal mechanical perception threshold,and blink frequency were measured before modeling,after modeling,and after treatment to observe the overall and ocular surface conditions of the rats.HE staining method was used to observe the morphology of rat cornea.Immunohistochemical,Western blot,and RT-PCR methods were used to determine the expression level of Caspase-1,IL-1 β and IL-18 in corneal tissue.Results Electroacupuncture can improve tear film rupture time,tear secretion,corneal sensitivity,promote corneal epithelial repair,and inhibit the expression level of Caspase-1,and its downstream IL-1 β and IL-18 in corneal tissue of type 2 diabetic dry eye rats.Conclusion The therapeutic effect of electroacupuncture on the ocular surface of type 2 diabetic dry eye rats is related to the anti-inflammatory effect of inhibiting the expression of Caspase-1 and its downstream IL-1 β and IL-18 in cornea.
