ObjectiveTo investigate the awareness and clinical practice of guidelines for the prevention and treatment of chronic hepatitis B （2022 edition） among clinicians. MethodsFrom July 19 to December 31， 2024， a self-designed electronic questionnaire was distributed via the WeChat mini program to collect related data from 1 588 clinicians nationwide， including their awareness and practice based on 18 questions regarding testing and referral， diagnosis and treatment， and follow-up. ResultsAmong all respondents， only 350 clinicians correctly understood all the updated key points of antiviral indications and treatment for special populations in the 2022 edition of guidelines for the prevention and treatment of chronic hepatitis B， with an overall awareness rate of 22.0%. Only 20% ‍—‍ ‍40% of the patients with positive HBV DNA and an age of >30 years receive antiviral therapy， while 80% ‍—‍ ‍100% of the patients with positive HBV DNA and a family history of hepatitis B cirrhosis or hepatocellular carcinoma receive antiviral therapy. The median follow-up rates at 1 year， 3 years， and 5 years were 67.5% 57.5% and 47.5%，respectively， showing a trend of gradual reduction， which might be associated with the influencing factors such as insufficient time for follow-up management by clinicians， insufficient awareness of the disease among patients， and poor adherence to follow-up. ConclusionThere is a gap between the awareness and practice of guidelines for the prevention and treatment of chronic hepatitis B （2022 edition） among clinicians. It is recommended to further strengthen training and focus on the whole process of “detection， diagnosis， treatment， and management” for patients with chronic hepatitis B in healthcare institutions， in order to promote the implementation of the guidelines.

OBJECTIVE Aimed to investigate the impact of comorbid asthma on chronic rhinosinusitis with nasal polyps(CRSwNP)and identify key proteins and signaling pathways.METHODS Proteomic methods were employed to analyze differentially expressed proteins(DEPs)in nasal lavage fluid(NLF)from control,CRSwNP,and CRSwNP with asthma groups.DIA quantitative analysis technology was used to assess the gradient changes of DEPs among the three groups to determine key proteins affected by comorbid asthma in CRSwNP.RESULTS Compared to the control group,1 377 and 1 006 DEPs were identified in the CRSwNP and CRSwNP with asthma groups,respectively.Peroxiredoxin-5(PRDX5),Ran-Binding Protein 1(RanBP1)(upregulated),and Keratin 9(KRT9)(downregulated)were identified as key proteins affecting CRSwNP with asthma.CONCLUSION Comorbid asthma may promote the occurrence and development of nasal polyps through specific key proteins and signaling pathways,providing new molecular insights into the interaction between CRSwNP and asthma.

Objective:To evaluate the efficacy and safety of antaitasvir phosphate 100 mg or 200 mg combined with yiqibuvir for 12 weeks in patients with various genotypes of chronic hepatitis C, without cirrhosis or compensated stage cirrhosis.Methods:Patients with chronic hepatitis C (without cirrhosis or compensated stage cirrhosis) were randomly assigned to the antaitasvir phosphate 100 mg+yiqibuvir 600 mg group (100 mg group) or the antaitasvir phosphate 200 mg+yiqibuvir 600 mg group (200 mg group) in a 1∶1 ratio. The drugs were continuously administered once a day for 12 weeks and observed for 24 weeks after drug withdrawal. The drug safety profile was assessed concurrently with the observation of the sustained virological response (SVR12) in the two patient groups 12 weeks following the drug cessation. The intention-to-treat concept was used to define as closely as possible a full analysis set, including all randomized cases who received the experimental drug at least once. The safety set was collected from all subjects who received the experimental drug at least once (regardless of whether they participated in the randomization group) in this study. All efficacy endpoints and safety profile data were summarized using descriptive statistics. The primary efficacy endpoint was SVR12. The primary analysis was performed on a full analysis set. The frequency and proportion of cases were calculated in the experimental drug group (antaitasvir phosphate capsules combined with yiqibuvir tablets) that achieved "HCV RNA

Purpose To investigate the predictive value of chest CT-based radiomics for spread through air spaces in stage T1 peripheral type lung cancer.Materials and Methods A total of 173 patients with surgically pathologically confirmed stage T1 non-small cell lung cancer were retrospectively collected and divided into positive group(49 cases)and negative group(124 cases)according to the presence or absence of spread through air spaces.All lesions were randomly divided into training set(122 cases)and validation set(51 cases)according to the ratio of 7∶3.The primary area of lung cancer(the main body of the lesion),the peripheral infiltrative area(a 5-mm annular area expanding outward along the edge of the lesion)and the tumor margin area(a 5-mm annular area retracting inward along the edge of the lesion)were used as areas of interest to extract imaging histological features.Three imaging histological models were established for the primary area of lung cancer,the peripheral infiltrative area and the tumor margin area,and combined with the morphological features of CT to establish three combined models.The efficacy of each model was evaluated and the optimal model was selected.Results The lobulation signs of positive group was significantly more than that of negative group(χ2=9.946,P=0.002).The area under the curve(AUC)of the imaging histological model based on the three regions of interest were 0.899,0.825,0.840 for the training group and 0.876,0.811 and 0.832 for the validation group,respectively.The model with the highest AUC was the primary tumor imaging model(P=0.043,P<0.001,P=0.017),the AUC of the combined model established by adding the lobar sign were 0.917,0.835 and 0.851,respectively.The AUC of the three regions of interest in the validation group were 0.912,0.832,and 0.845 and the highest AUC was found in the primary tumor area(P<0.001,P=0.017,P=0.049).Conclusion It is feasible to study lung cancer with airway metastasis via CT-based radiomics,taken lobulation signs as the risk predictive factor.

Objective To explore the association between peripheral retinal defocus and myopia in adolescents.Methods This study encompassed 192 adolescents(192 right eyes),aged between eight and fifteen years,who sought treatment at Ineye Hospital of Chengdu University of TCM from October 2022 to April 2023.Based on the spherical equiva-lent(SE),the patients were divided into three groups:Emmetropia(E),low myopia(LM),and moderate myopia(MM),with each group comprising 64 patients(64 right eyes).After mydriatic refraction,the SE values were documen-ted.Ocular biological parameters,including axial length(AL),central corneal thickness(CCT),lens thickness(LT),and keratometry values(K1,K2),were obtained using IOL Master 900.Multispectral refraction topography was employed to measure the retinal defocus:positive values indicated hyperopic defocus,while negative ones represented myopic defocus.With the macular fovea as the center,the total retinal defocus value was recorded as TRDV.The ring partition(eccentrici-ty)was divided into 0°-10°、＞10°-20°、＞20°-30°、＞30°-40°、＞40°-53°,which was recorded as RDV-0°-10°,RDV-10°-20°,RDV-20°-30°,RDV-30°-40°,and RDV-40°-53°,respectively;the quadrants were recorded as RDV-Superior(RDV-S),RDV-Inferior(RDV-I),RDV-Temporal(RDV-T)and RDV-Nasal(RDV-N),respectively.The variance of RDV across different ranges was analyzed using One-Way ANOVA and non-parametric tests.The associations between SE,AL and RDV were examined using Spearman and Pearson correlation analyses.Results The RDV-20°-30°,RDV-30°-40° and RDV-40°-53° of Groups E,LM and MM all exhibited hyperopic defocus.Statistically significant differences were identi-fied in TRDV,RDV-10°-20°,RDV-20°-30°,RDV-30°-40°,RDV-40°-53°,RDV-S,RDV-T and RDV-N among the three groups(all P＜0.05).TRDV,RDV-20°-30°,RDV-30°-40°,RDV-40°-53°,RDV-S,RDV-T,and RDV-N were found to be negatively correlated with SE while positively correlated with AL(all P＜0.05).RDV-0°-10° and RDV-I were uncorrelated with both SE and AL(all P＞0.05);RDV-10°-20° was positively correlated with AL(P=0.012)while uncorrelated with SE(P=0.233).Conclusion Peripheral retinal hyperopic defocus tends to advance with escalating eccentricity and my-opia.Peripheral retinal defocus is asymmetrical.Peripheral(10°-53°),superior,nasal and temporal retinal defocus may be closely related to the development of myopia.

Objective To explore the changes in periretinal defocus and visual quality after femtosecond laser-assis-ted in situ keratomileusis(FS-LASIK).Methods Fifty-one myopic patients(102 eyes)who underwent FS-LASIK at the Ineye Hospital of Chengdu University of Traditional Chinese Medicine from March to May 2023 were selected for the study,including 27 females(54 eyes)and 24 males(48 eyes).The defocus around the retina was measured using a multispectral refraction topography,and the total refraction difference value(TRDV)was recorded.The refraction difference value(RDV)in four quadrants:superior RDV(RDV-S),inferior RDV(RDV-I),nasal RDV(RDV-N),and temporal RDV(RDV-T),as well as the RDV in the concentric ring areas corresponding to 10°,20°,30°,40°,and 53° from the fovea of the mac-ula(represented as RDV 0°-10°,RDV 10°-20°,RDV 20°-30°,RDV 30°-40°,and RDV 40°-53°,respectively)were also re-corded.The objective scattering index(OSI),Strehls ratio(SR),modulation transfer function(MTF)values(represen-ted as 10 c·d-1 MTF,20 c·d-1 MTF,and 30 c·d-1MTF,respectively)and cutoff frequencies(MTF cutoff)at the spa-tial frequencies of 10 c·d-1,20 c·d-1 and 30 c·d-1 were measured and recorded using a visual quality analysis system.The data of corneal vertical trefoil(Z3-3),vertical coma(Z3-1),horizontal coma(Z31),horizontal trefoil(Z33),vertical tetrafoil(Z4-4),vertical secondary astigmatism(Z4-2),spherical aberration(Z40),horizontal secondary astigmatism(Z42),horizontal tetrafoil(Z44),and total higher-order aberration(HOA)were measured and recorded using the iTrace aberration meter.The measurement data of patients before surgery,one month after surgery,and three months after sur-gery were compared,and their correlations were analyzed.Results TRDV,RDV-S,RDV-N,RDV 20°-30°,RDV 30°-40°,and RDV 40°-53° around the retina of patients decreased one month and three months after surgery compared with those be-fore surgery,and the differences were statistically significant(all P＜0.001).There were statistically significant differences in OSI,MTF cutoff,and 10 c·d-1 MTF among patients before surgery,one month after surgery,and three months after surgery(all P＜0.05).There were statistically significant differences in corneal Z3-3,Z3-1,Z31,Z33,Z4-4,Z4-2,Z40,Z42,Z44,and HOA among patients before surgery,one month after surgery,and three months after surgery(all P＜0.001).The Pearson correlation analysis results showed that,ΔRDV 0°-10° was positively correlated with ΔZ3-3,ΔZ31,ΔZ4-2,ΔZ40,and ΔZ42(all P＜0.05);ΔRDV 10°-20° was positively correlated with ΔZ4-4 and ΔZ4-2(both P＜0.05);ΔRDV 20°-30° was positively correlated with ΔZ4-4 and ΔZ44(both P＜0.05);ΔTRDV and ΔRDV 40°-53° were negatively correla-ted with ΔHOA(both P＜0.05).ΔRDV-S and ΔZ3-1 were negatively correlated with ΔHOA(both P＜0.05)and positively correlated with ΔZ44(P＜0.05);ΔRDV-N was positively correlated with ΔZ4-4(P＜0.05).Conclusion FS-LASIK can reduce periretinal hyperopic defocus in myopic patients,but it introduces corneal HOA,and there is a certain correlation between the two.
