Objective To analyze the newly reported HIV-1 infection in several prefectures of Hubei Province，and analyze its influencing factors. Methods The limiting antigen avidity enzyme immunoassay(LAg-avidity EIA,LAg) was conducted on HIV-1 positive samples confirmed by Western blot of Hubei in 2017-2022. The demographic characteristics of the newly infected samples were analyzed by χ2 test.Logistic regression model was used to analyze influencing factors of new infection rate and predict the factors associated with the HIV-1 recent infection. Results There were 403 new cases of HIV-1 from 2017 to 2022 in several prefectures of Hubei Province, of which 77 were newly infected sorted by LAg,with a new infection rate of 19.11%. The newly confirmed HIV-1 persons of whom aged ≤24 years (40.00% new infection ratio), unmarried (29.41%), college or above (31.37%), and from Voluntary counseling and testing testing(VCT) clinics (40.00%) had a higher proportion of new infections, and the difference was statistically significant. Multivariate Logistic regression analysis showed that age ≤24 years old (aOR=4.346,95%CI: 1.342-14.075) and screening from the VCT clinic (aOR=6.761,95%CI: 1.460-31.319) were more likely to be newly infected. Conclusion The proportion of new HIV infection in several prefectures of Hubei province is relatively low in recent years.Further effective publicity and intervention measures for young students and the construction of VCT clinic should be continuously promoted to achieve early diagnosis and treatment.

ObjectiveTo investigate the association of the traditional Chinese medicine （TCM） syndrome types of primary liver cancer （PLC） with clinical features and multimodal quantitative radiological features on computed tomography （CT） and magnetic resonance imaging （MRI）， and to provide a reference for the objectification of TCM syndrome differentiation and precise diagnosis and treatment. MethodsA retrospective analysis was performed for the clinical data of 312 patients who were diagnosed with PLC in The First Affiliated Hospital of Hunan University of Chinese Medicine from March 2020 to June 2025， and according to the TCM syndrome type， they were divided into stagnation of liver Qi group with 40 patients， stagnation of liver Qi and spleen deficiency group with 109 patients， Qi stagnation and blood stasis group with 62 patients， dampness-heat toxin amassment group with 81 patients， and liver-kidney Yin deficiency group with 20 patients. Clinical features and multimodal quantitative radiological features were compared between the patients with different TCM syndrome types. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups； the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups， and the Dunn’s multiple test was used for further comparison between two groups； the chi-square test was used for comparison of categorical data between groups， and the Bonferroni method was used for further comparison between two groups. ResultsThere were significant differences between the patients with different TCM syndrome types in China liver cancer staging （CNLC）， Child-Pugh class， alanine aminotransferase， aspartate aminotransferase， albumin， direct bilirubin， total bilirubin， prothrombin time， neutrophil， and albumin-bilirubin score （all P<0.05）. In the stagnation of liver Qi group， the patients with Child-Pugh class A accounted for 75.00%； among the patients with CNLC stage I PLC， the patients with stagnation of liver Qi accounted for 60.00%， and those with Qi stagnation and blood stasis syndrome accounted for 59.68%， while among the patients with CNLC stage IV PLC， the distribution proportion of dampness-heat toxin amassment （27.16%） and liver-kidney Yin deficiency （30.00%） was significantly higher than that of stagnation of liver Qi （2.50%） （all P<0.05）. Radiological examination showed that there were significant differences between the patients with different TCM syndrome types in the number of tumors， ascites， venous tumor thrombus， maximum tumor diameter， intrahepatic metastasis， and lymph node metastasis in the hepatic hilar and retroperitoneal regions （all P<0.05）. Compared with the patients with stagnation of liver Qi， the patients with liver depression and spleen deficiency or liver-kidney Yin deficiency were more likely to develop intrahepatic metastasis； the patients with liver depression and spleen deficiency， dampness-heat toxin amassment， or liver-kidney Yin deficiency were more likely to develop lymph node metastasis in the hepatic hilar and retroperitoneal regions； the patients with liver-kidney Yin deficiency were more likely to experience multiple tumors； the patients with liver depression and spleen deficiency or dampness-heat toxin amassment were more likely to develop ascites （all P<0.05）. Compared with the patients with Qi stagnation and blood stasis syndrome， the patients with liver depression and spleen deficiency had a significantly longer maximum tumor diameter and a significantly higher proportion of patients with venous tumor thrombus （both P<0.05）. Furthermore， among the 184 patients with MRI diffusion-weighted imaging sequences， the patients with dampness-heat toxin amassment or Qi stagnation and blood stasis syndrome had significantly higher ADC values and relative ADC values than those with stagnation of liver Qi （all P<0.05）. ConclusionThere are significant differences in CT/MRI radiological features and clinical features between PLC patients with different TCM syndrome types， among whom the patients with liver depression and spleen deficiency， dampness-heat toxin amassment， and liver-kidney Yin deficiency tend to exhibit progressive radiological features， and those with dampness-heat toxin amassment or Qi stagnation and blood stasis syndrome tend to have higher ADC values. These findings provide an objective basis for TCM syndrome differentiation in PLC.

ObjectiveTo investigate the expression level of mammalian sterile 20-like kinase 1 （MST1） in prostate cancer （PCa） tissues， its biological functions， and its regulatory effects on androgen receptor （AR） and vascular endothelial growth factor （VEGF） expression. MethodsImmunohistochemistry was performed to detect MST1 expression in 77 prostate cancer tissues and 34 benign prostatic hyperplasia （BPH） tissues， and the relationship between MST1 expression and clinicopathological parameters was analyzed. MST1-overexpressing C4-2 and LNCaP cell lines were constructed. CCK-8 assay， Transwell migration assay， and angiogenesis assay were conducted to evaluate the effects of MST1 on cell proliferation， migration， and angiogenesis. The expression changes of AR and VEGF were detected by qRT-PCR and Western blot. ResultsMST1 expression was significantly lower in PCa tissues compared with BPH tissues （P=0.012）. Low MST1 expression was significantly associated with tumor metastasis （P=0.033）. MST1 overexpression inhibited C4-2 cell proliferation and migration， with transmembrane migrated cells reduced by 53.6% （P<0.01）. MST1 overexpression decreased the mRNA and protein expression levels of AR and VEGF （P<0.05）. Angiogenesis assay demonstrated that the length of new vessel structure was significantly reduced （P<0.05）. ConclusionMST1 shows a low expression level in PCa tissues and is associated with tumor metastasis. MST1 exerts tumor-suppressive effects in prostate cancer by inhibiting cell proliferation， migration， and angiogenesis， as well as downregulating the expression of AR and VEGF， indicating its potential as a therapeutic target for prostate cancer.

AIM: To explore the factors influencing heart rate(HR)changes during small incision lenticule extraction(SMILE)surgery by monitoring HR trends at different time points of the procedure.METHODS: Prospective cohort study. A total of 69 patients who underwent SMILE surgery at the Laser Vision Correction Center of Xi'an No.1 Hospital from April to May 2024 were enrolled. Before the surgery, patients completed the State Anxiety Inventory(S-AI, questions 1-20)to assess their preoperative anxiety scores related to the next day's surgery. Baseline HR was recorded using medical pulse oximeter, and real-time HR was recorded during patient positioning, lenticule scanning, lenticule separation and extraction, and the application of postoperative eye drops.RESULTS: The HR during patient positioning was 83.61±13.87 bpm, which was significantly different from the baseline HR(77.52±10.88 bpm), HR during lenticule separation and extraction(75.54±12.52 bpm), and HR during postoperative eye drop application(76.65±10.54 bpm; all P<0.001). When stratified by median age, older patients(>26 years)had the HR during lenticule separation and extraction 76.27±9.93 bpm, which differed from the HR at positioning(84.82±14.10 bpm)and at lens scanning(82.76±13.72 bpm; all P<0.005). Stratified by gender, the HR of male patients at positioning was the highest(85.31±16.61 bpm), which differed significantly from the baseline HR(78.26±12.63 bpm), HR during lenticule separation and extraction(77.14±14.59 bpm), and HR during postoperative eye drop application(77.11±12.49 bpm; all P<0.005). There was no correlation between HR during positioning and preoperative anxiety scores(r=0.124, P=0.418).CONCLUSION: HR changes during SMILE surgery vary with different procedural stages, peaking during patient positioning and reaching the lowest point during lenticule separation and extraction. Older patients showed higher HR during positioning, and male patients exhibited higher HR during positioning.

Objective To analyze the activity concentrations of gross α, gross β, and radionuclides in atmospheric fallout around Daya Bay Nuclear Power Plant from 2019 to 2022, and provide foundational scientific data for the healthy development of nuclear energy. Methods Five monitoring sites were set up at different distances (1.2, 6.9, 12.4, 42.3, and 69.2 km) from Daya Bay Nuclear Island 1. Stainless steel sampling barrels were used to collect atmospheric fallout, with a monitoring cycle of three months. The collected samples were ashed using radiochemical method. Subsequently, the gross α and gross β radioactivity were quantified using a low-background α/β measurement instrument. The remaining ash samples were mixed with water and left to equilibrate for over three weeks before γ-nuclide analysis using a low-background, high-purity germanium γ-spectrometer. Results The gross α activity concentration in atmospheric fallout around Daya Bay Nuclear Power Plant from 2019 to 2022 averaged (25.3 ± 10.6) Bq/m²/season and ranged from 5.8 to 73.4 Bq/m²/season. The gross α activity concentrations in sampling sites #1 to #5 were 5.8-34.4, 11.9-35.2, 14.4-46.4, 7.2-73.4, and 13.1-43.1 Bq/m²/season, respectively. The gross β activity concentration averaged (50.5 ± 23.4) Bq/m²/season and ranged from 13.9 to 139.3 Bq/m²/season. The gross β activity concentrations of sampling sites #1 to #5 were 17.1-107.4, 17.6-87.5, 25.8-102.0, 13.9-139.3, and 23.4-99.2 Bq/m²/season, resprctively. The activity concentrations of ²³⁸U, ²²⁶Ra, ²³²Th, ⁴⁰K, ²¹⁰Pb, and ⁷Be in atmospheric fallout were < lower limit of detection (LLD)-4.2, < LLD-5.8, < LLD-6.3, < LLD-42.1, < LLD-514.0, and 35.7-1761.0 Bq/m²/season, respectively. Gross α and gross β activity concentrations were significantly positively correlated with ²¹⁰Pb activity concentration (r=0.770, α < 0.001; r=0.882, α < 0.001, respectively). Gross β activity concentration showed a significant positive correlation with ⁷Be (r=0.833, α < 0.001). The activity concentrations of ⁵⁴Mn, ⁵⁷Co, ⁵⁸Co, ⁶⁰Co, ⁵⁹Fe, ⁹⁵Zr, ¹⁰³Ru, ¹⁰⁶Ru, ^110mAg, ¹³¹I, ¹³⁴Cs, ¹³⁷ Cs, ¹⁴⁰Ba and ¹⁹²Ir were lower than the LLD of the instrument, and no artificial radionuclides were detected. Conclusion The gross α and gross β radioactive activity concentrations in the atmospheric fallout in the surrounding area of Daya Bay Nuclear Power Plant during 2019-2022 were affected by natural radionuclides ²¹⁰Pb and ⁷Be, and were in the normal fluctuation ranges. No artificial radionuclides were found in the atmospheric fallout, and the Daya Bay Nuclear Power Plant was in a safe and stable state of operation.

Objective:To investigate the therapeutic efficacy of programmed death-1(PD-1)inhibitors in combination with drug-eluting beads transcatheter arterial chemoembolization(DEB-TACE)and radiofrequency ablation(RFA), as well as their impact on the prognosis of older patients with primary hepatocellular carcinoma(HCC).Methods:In this prospective cohort study, 120 patients aged 65 years and older with HCC at stage Ⅱb-Ⅲb were randomly assigned to an observation group (n=60)and a control group (n=60)between January 2021 and January 2024.The control group received DEB-TACE followed by RFA, while the observation group received a PD-1 inhibitor in combination with DEB-TACE followed by RFA, with both interventions lasting for 12 weeks.The clinical efficacy of the treatments in both groups was assessed, and changes in serum tumor markers before and after treatment were compared between the two groups.Safety was evaluated, survival data were recorded during follow-up, and the effects of different therapeutic regimens on patient prognosis were analyzed.Results:The disease control rate(DCR)and objective response rate(ORR)in the observation group were 88.33% and 78.33%, respectively, which were higher than those in the control group (71.67% and 28.33%, χ2=5.208, 30.134, P=0.022, <0.001). After treatment, levels of serum tumor markers (alpha fetoprotein, carbohydrate antigen 125, vascular endothelial growth factor)decreased in both groups (all P<0.05), with levels in the observation group being lower than those in the control group (all P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups (all P>0.05). By the end of follow-up, which ranged from 2 to 33 months, there were 15 death cases in the observation group, resulting in a cumulative survival rate of 75.00%(45/60) and a mean survival of 25.95 months.In the control group, there were 25 death cases, with a cumulative survival rate of 58.33%(35/60)and a mean survival of 20.33 months.The results of the Kaplan-Meier function analysis were as follows: Log-rank χ2=5.747, P=0.017; Breslow χ2=3.124, P=0.077.The results of the multivariate Cox regression analysis indicated that PD-1 inhibitor combined with DEB-TACE sequential RFA was a protective factor against death in older patients with primary HCC( HR=0.680, 95% CI: 0.463-0.998, P=0.014). Conclusions:The curative effect and safety of PD-1 inhibitor combined with DEB-TACE and RFA are favorable in older patients with advanced HCC.

Objective To establish the reference interval of urine Alzheimer-associated neuronal thread protein(AD7c-NTP)for healthy adults in Mianyang area using the indirect method.Methods The detection results of urine AD7c-NTP from 5 093 healthy in-dividuals were collected from the information management database of Medical Laboratory Department of Sichuan Science City Hospital from March 2017 to March 2022.Skewness-kurtosis and Kolmogorov-Smirnov tests were used to determine whether the data followed a normal distribution.After removing outliers using the Box Plots method,the enrolled subjects were grouped by gender and age.The Mann-Whitney U or Kruska-Wallis H tests were used to analyze the between-group differences of urine AD7c-NTP in healthy individu-als with different genders and ages.The adjacent age groups without statistically significant difference(P＞0.05)were combined,and the indirect method(non-parametric test method)was used to calculate the reference intervals for different gender and age groups.Results Skewness-kurtosis and Kolmogorov-Smirnov tests showed that the data followed a non-normal distribution.After removing 293 outliers using the Box Plots method,a total of 4 800 subjects,including 3 199 males and 1 601 females,were enrolled.The enrolled subjects were grouped by gender and age,and the non-parametric test method were used to establish the reference intervals of urine AD7c-NTP in healthy populations with different genders.The Mann-Whitney U test confirmed that urine AD7c-NTP levels existed gen-der differences(Z=14.09,P＜0.01),and the reference intervals for males and females were≤1.10 ng/mL and≤1.40 ng/mL,re-spectively.There were also statistical differences in urine AD7c-NTP levels among different age groups of the same gender.After combi-ning adjacent age groups without statistically significant difference(P＞0.05),the reference intervals of urine AD7c-NTP in healthy populations with different genders and ages were established by the non-parametric test method,which were≤1.00 ng/mL for male 20-39 years old group,≤1.10 ng/mL for male 40-79 years old group,≤1.60 ng/mL for male≥80 years old group,≤1.30 ng/mL for female 20-69 years old group,and≤1.60 ng/mL for female≥70 years old group,respectively.The established reference intervals of urine AD7c-NTP were further verified by healthy individuals,and the results met the standards.Conclusion The reference intervals of urine AD7c-NTP in healthy populations with different genders and ages in Mianyang area are established successfully using the indi-rect method,which may help to predict the risk of Alzheimer's disease in clinical practice and provide support for the diagnosis and treatment of the disease.

Three throat swab samples from infants and young children in Hubei Province were identified as positive for enteroviruses. All subjects were one month old, and the onset of symptoms occurred in June; these cases were sporadic and exhibited no clear epidemiological associations. The results of VP1 gene amplification analysis indicated that all three infant cases were attributed to Echovirus 30 (ECHO30). The ECHO30 strain isolated from the three samples was classified as Cluster Ⅲ within the H gene subtype. Whole genome amplification analysis revealed that the ECHO30 strain from Hubei exhibited the highest homology with ECHO30/MW586892/Ashburton/17WQ2027G/USA/2007-08-20 from GenBank, demonstrating nucleotide and amino acid homologies of 97.6% and 99.3%, respectively. Recombination analysis indicated the presence of recombination events in the non-structural protein region of the ECHO30 Hubei strain, with recombinant fragments potentially originating from ECHO30/KY888274/14-397/Germany/2013 and ECHO18 strains Echo18/MN815811/BJ2018-S6363/Beijing/2018. This study provides a comprehensive analysis of the genetic evolution of the ECHO30 strain prevalent in Hubei Province, contributing essential data for the prevention of ECHO30 infections.
