Dynamic evaluation of liver fibrosis to assess hepatocellular carcinoma risk in patients with chronic hepatitis B receiving nucleoside analogs treatment

ABSTRACT Despite good hepatitis B virus (HBV) inhibition by nucleoside analogs (NAs), cases of hepatocellular carcinoma (HCC) still occur. This study proposed a non-invasive predictive model to assess HCC risk in patients with chronic hepatitis B (CHB) receiving NAs treatment. Data were obtained from a hospital-based retrospective cohort registered on the Platform of Medical Data Science Academy of Chongqing Medical University, from 2013 to 2019. A total of 501 patients under NAs treatment had their FIB-4 index updated semiannually by recalculation based on laboratory values. Patients were divided into three groups based on FIB-4 index values: < 1.45, 1.45-3.25, and ≥ 3.25. Subsequently, HCC incidence was reassessed every six months using Kaplan-Meier curves based on the updated FIB-4 index. The median follow-up time of CHB patients after receiving NAs treatment was 2.5 years. HCC incidences with FIB-4 index < 1.45, 1.45-3.25, and ≥ 3.25 were 1.18%, 1.32%, and 9.09%, respectively. Dynamic assessment showed that the percentage of patients with FIB-4 index < 1.45 significantly increased semiannually (P < 0.001), and of patients with FIB-4 index ≥ 3.25 significantly decreased (P < 0.001). HCC incidence was the highest among patients with FIB-4 index ≥ 3.25. The FIB-4 index effectively predicted HCC incidence, and its dynamic assessment could be used for regular surveillance to implement early intervention and reduce HCC risk.

Analysis of correlation between medial joint line change and lower limb coronal alignment after Oxford unicompartmental knee arthroplasty

Abstract Background: Lower limb coronal alignment was thought to be a predictive factor for Unicompartmental Knee Arthroplasty (UKA) result. The tibial bony resection and implant position lead to joint line change postoperatively. Analysis was done to find out the correlation between these factors. Methods: From 2019 to 2021, 90 medial Oxford UKA were implanted by a single surgeon. Hip Knee Ankle Angle (HKAA), Lateral Distal Femoral Angle (LDFA), Medial Proximal Tibial Angle (MPTA), and intraoperative bony resection thickness were measured. The medial joint line change was calculated. The correlation between joint line change and alignment change was evaluated. Results: The mean tibial resection thickness was 4.3 mm. The mean tibial joint line was elevated by 2.3 mm, while the mean femoral joint line proximalized by 0.8 mm. HKAA changed from 8.4° varus preoperatively to 3.6° varus postoperatively. LDFA changed from 89.0° to 86.7°. MPTA changed from 85.6° to 86.6°. Preoperative HKAA showed a strong correlation with postoperative HKAA (p < 0.001), and preoperative MPTA showed a positive correlation with postoperative HKAA (p < 0.001). While preoperative LDFA had a negative correlation with postoperative HKAA (p < 0.001). The femoral joint line change and LDFA change had a significant correlation with HKAA change (p < 0.05). Conclusion: The change of joint line had no correlation with postoperative HKAA in Oxford UKA. Preoperative HKAA strongly correlated with postoperative HKAA; while preoperative smaller LDFA and larger MPTA had a moderate correlation with postoperative HKAA. The femoral joint line change and LDFA change had a weak to moderate correlation with HKAA change.

Bidirectional associations between hyperopia, myopia, astigmatism, and strabismus, and attention-deficit/hyperactivity disorder in children: a national population-based cohort study

Objectives: The present study analyzed the reciprocal relationships between four common pediatric ophthalmic diseases (i.e., hyperopia, myopia, astigmatism, and strabismus) and attention‐deficit/hyperactivity disorder (ADHD) in children. Methods: This study enrolled 86,028 children with ADHD and 1,798,673 children without ADHD in the Taiwan Maternal and Child Health Database who were born at any time from 2004 to 2017. Cox proportional hazards regression models were used to estimate the bidirectional relationships of the four ophthalmic diseases with ADHD in children after adjusting for age, sex, and gestational age at birth. Survival curves for time-to-event variables were estimated using the Kaplan-Meier method, and the log-rank test was used to compare the curves. Results: The results indicated that ADHD significantly predicted the occurrence of hyperopia, myopia, astigmatism, and strabismus. Furthermore, hyperopia, myopia, astigmatism, and strabismus significantly predicted the occurrence of ADHD. The time between enrollment and ADHD diagnosis was shorter for patients with ophthalmic diseases than for the control group, and the time between enrollment and ophthalmic disease diagnosis was also shorter for ADHD patients than for the control group. Sex differences were found in the associations between ADHD and ophthalmic diseases. Conclusion: Clinicians should monitor children with ADHD for hyperopia, myopia, astigmatism, and strabismus to ensure appropriate treatment, and vice versa.

Surgical decisions and outcomes of rhegmatogenous retinal detachment during the coronavirus disease 2019 pandemic: Data from a tertiary referral center in Taiwan

Purpose: To assess changes in surgical decisions and outcomes of rhegmatogenous retinal detachment (RRD) during the COVID?19 pandemic at a tertiary center in Taiwan. Methods: Patients undergoing pars plana vitrectomy (PPV) or scleral buckling (SB) for primary RRD during Taiwan’s first wave of domestic COVID?19 cases surge between May and July 2021 (COVID cohort, n = 100) were compared to controls in the closest pre?COVID year, 2019 (pre?COVID cohort, n = 121). Results: The COVID cohort had significantly worse RRD presentation, received more PPV (alone or combined with SB (PPV + SB)) and less SB alone, and had comparable single?surgery anatomic success (SSAS) rates. In patients who underwent PPV, more underwent PPV + SB instead of PPV alone. The decision to combine SB in PPV surgery was significantly affected by the COVID pandemic (odds ratio [OR], 3.1860 [95% confidence interval (CI), 1.1487–8.8361]). However, a shorter duration of symptoms before the first presentation (0.9857 [95% CI, 0.9720–0.9997]) was the only factor related to SSAS, whereas the surgical method had no association. The SSAS rate remained close to or over 90% in patients with a duration of symptoms before surgery ?4 weeks but dropped to 83.3% in patients with duration >4 weeks. Conclusion: During the COVID?19 pandemic, worse RRD presentations led to a shift in preference for PPV over SB alone as the primary surgery. The pandemic affected surgeons’ decision to combine SB during PPV. Nevertheless, SSAS was only associated with the duration of symptoms but not with surgical methods.

Cardiovascular health status of Chinese adults based on "Life's Essential 8" score / 中华流行病学杂志

Objective: To assess the cardiovascular health status of adults in China by using the "Life's Essential 8" score, and provide reference for the development and improvement of cardiovascular disease prevention and control policies and measures. Methods: Chronic Disease and Nutrition Surveillance was conducted in 298 counties/districts in 2015 in 31 provinces (autonomous regions, municipalities) across China, multi-stage stratified cluster random sampling was used to select 45 households in each village or neighborhood, and 20 households were further selected to conduct dietary surveys. In this study, a total of 70 093 adults aged ≥20 years who completed the dietary survey and had complete information were included, their cardiovascular health status were assessed by using the "Life's Essential 8" score, a cardiovascular health scoring standard released by the American Heart Association in 2022. All results were adjusted using complex design-based sampling weights to achieve a better estimate of the population. Results: In 2015, the overall cardiovascular health score of Chinese adults aged ≥20 years was 73.3±12.6, the score was significantly higher in women (77.9±11.6) than in men (68.7±11.8), and higher in urban area (74.5±12.8) than in rural area (71.9±12.2), the differences were significant (P<0.001). It was estimated that about 0.25% (95%CI: 0.16%-0.33%) of adults in China had cardiovascular health score of 100, and 33.0% (95%CI: 31.6%-34.3%), 63.2% (95%CI: 62.1%-64.3%), and 3.9% (95%CI: 3.5%-4.2%) of adults had high, moderate and low cardiovascular health scores, respectively. The proportion of those with high cardiovascular health scores was relatively low in men, those with low education level, those with low income, those living in rural areas, and those living in southwest China (P<0.001). Of the eight factors, diet had the lowest mean score (46.0, 95%CI: 44.7-47.3), followed by blood pressure (59.4, 95%CI: 58.2-60.6) and tobacco exposure (61.4, 95%CI: 60.6-62.2). Conclusions: The cardiovascular health status of two-thirds of adult population in China needs to be improved. Diet, tobacco exposure, and blood pressure are the factors affecting the cardiovascular health of Chinese population, to which close attention needs to be paid, and men, rural residents, and those with lower socioeconomic status are key groups in cardiovascular health promotion.

Marginal adaptation and mechanical strength of endocrowns with different materials and tooth prepration design: a review / 口腔疾病防治

@#The endocrown, a modified overlay or crown, is considered to have the advantages of adhesive retention and mechanical retention. Marginal adaptation and mechanical strength are common criteria for evaluating endocrowns. This review studied these aspects of endocrowns to guide further clinical application. Results from previous academic studies indicate that endocrowns made of different materials, such as glass-based ceramics, zirconia-based ceramics and resin-based ceramics, exhibit clinically acceptable marginal adaptation. Zirconia is a common dental material, but when used in endocrowns, it tends to present a risk of irreparable tooth root fractures. Compared with products manufactured with zirconia, endocrowns manufactured with resin-based ceramics and glass-based ceramics, such as lithium disilicate ceramics, do not tend to cause irreparable results, such as tooth root fracture, but their mechanical strengths are not as good as those of zirconia. At the same time, the tooth prepration design such as the types of endocrowns, the pulp chamber extension depth and angles, the endocrown thickness can influence the mechanical strength of endocrowns as well. Compared with traditional zirconia, self-glazed zirconia, a new type of material used to restore defective teeth, has the similar elasticity modulus（210 GPa）and better aesthetic advantages, and is suitable for short crown patients with insufficient occlusal space. Further study is warranted to improve the performance of endocrowns made from ceramic materials to prevent root fracture.

Association of Increased Amygdala Activity with Stress-Induced Anxiety but not Social Avoidance Behavior in Mice / 神经科学通报·英文版

Chronic stress leads to many psychiatric disorders, including social and anxiety disorders that are associated with over-activation of neurons in the basolateral amygdala (BLA). However, not all individuals develop psychiatric diseases, many showing considerable resilience against stress exposure. Whether BLA neuronal activity is involved in regulating an individual's vulnerability to stress remains elusive. In this study, using a mouse model of chronic social defeat stress (CSDS), we divided the mice into susceptible and resilient subgroups based on their social interaction behavior. Using in vivo fiber photometry and in vitro patch-clamp recording, we showed that CSDS persistently (after 20 days of recovery from stress) increased BLA neuronal activity in all the mice regardless of their susceptible or resilient nature, although impaired social interaction behavior was only observed in susceptible mice. Increased anxiety-like behavior, on the other hand, was evident in both groups. Notably, the CSDS-induced increase of BLA neuronal activity correlated well with the heightened anxiety-like but not the social avoidance behavior in mice. These findings provide new insight to our understanding of the role of neuronal activity in the amygdala in mediating stress-related psychiatric disorders.

Enzyme-linked immunosorbent assays for quantification of MMMAE-conjugated ADCs and total antibodies in cynomolgus monkey sera / 药物分析学报

Antibody-drug conjugates(ADCs)are commonly heterogeneous and require extensive assessment of exposure-efficacy and exposure-safety relationships in preclinical and clinical studies.In this study,we report the generation of a monoclonal antibody against monomethyl auristatin E(MMAE)and the development,validation,and application of sensitive and high-throughput enzyme-linked immunosor-bent assays(ELISA)to measure the concentrations of MMAE-conjugated ADCs and total antibodies(tAb,antibodies in ADC plus unconjugated antibodies)in cynomolgus monkey sera.These assays were suc-cessfully applied to in vitro plasma stability and pharmacokinetic(PK)studies of SMADC001,an MMAE-conjugated ADC against trophoblast cell surface antigen 2(TROP-2).The plasma stability of SMADC001 was better than that of similar ADCs coupled with PEG4-Val-Cit,Lys(m-dPEG24)-Cit,and Val-Cit linkers.The developed ELISA methods for the calibration standards of ADC and tAb revealed a correlation be-tween serum concentrations and the OD450 values,with R2 at 1.000,and the dynamic range was 0.3-35.0 ng/mL and 0.2-22.0 ng/mL,respectively;the intra-and inter-assay accuracy bias％ranged from-12.2％to-5.2％,precision ranged from-12.4％to-1.4％,and the relative standard deviation(RSD)was less than 6.6％and 8.7％,respectively.The total error was less than 20.4％.The development and validation steps of these two assays met the acceptance criteria for all addressed validation parameters,which suggested that these can be applied to quantify MMAE-conjugated ADCs,as well as in PK studies.Furthermore,these assays can be easily adopted for development of other similar immunoassays.

An increased risk of influenza epidemic is predicted in collective units such as schools and kindergartens, yet the risk of a large-scale one will be low.@*Conclusion@#High attention should be paid to COVID-19 and enteritis due to norovirus, and general attention should be paid to chicken pox and influenza outbreak.

Peripheral zone PSA density: a predominant variable to improve prostate cancer detection efficiency in men with PSA higher than 4 ng ml / 亚洲男科学杂志(英文版)

To improve the diagnostic efficiency of prostate cancer (PCa) and reduce unnecessary biopsies, we defined and analyzed the diagnostic efficiency of peripheral zone prostate-specific antigen (PSA) density (PZ-PSAD). Patients who underwent systematic 12-core prostate biopsies in Shanghai General Hospital (Shanghai, China) between January 2012 and January 2018 were retrospectively identified (n = 529). Another group of patients with benign prostatic hyperplasia (n = 100) were randomly preselected to obtain the PSA density of the non-PCa cohort (N-PSAD). Prostate volumes and transition zone volumes were measured using multiparameter magnetic resonance imaging (mpMRI) and were combined with PSA and N-PSAD to obtain the PZ-PSAD from a specific algorithm. Receiver operating characteristic (ROC) curve analysis was used to assess the PCa detection efficiency in patients stratified by PSA level, and the area under the ROC curve (AUC) of PZ-PSAD was higher than that of PSA, PSA density (PSAD), and transition zone PSA density (TZ-PSAD). PZ-PSAD could amend the diagnosis for more than half of the patients with inaccurate transrectal ultrasonography (TRUS) and mpMRI results. When TRUS and mpMRI findings were ambiguous to predict PCa (PIRADS score ≤3), PZ-PSAD could increase the positive rate of biopsy from 21.7% to 54.7%, and help 63.8% (150/235) of patients avoid unnecessary prostate biopsy. In patients whose PSA was 4.0-10.0 ng ml

SUMMARY OBJECTIVE This study aims to investigate the application value of magnetic resonance (MR) hydrography of the inner ear in cochlear implantation. METHODS 146 patients were enrolled. MR hydrography and spiral CT examinations for the intracranial auditory canal were performed before surgery, and all imaging results were statistically analyzed in order to explore the application value of MR hydrography of the inner ear in cochlear implantation. RESULTS 146 patients (292 ears) were examined. Among these patients, 13 were diagnosed with abnormal vestibular aqueducts (20 ears) by MR hydrography, while five were diagnosed with this disease by CT; 15 patients were diagnosed with inner ear malformation (19 ears) by MR hydrography, while 11 were diagnosed by CT (four were misdiagnosed); five patients were diagnosed with internal acoustic canal stenosis (eight ears) by MR hydrography, while two were diagnosed by CT (three were misdiagnosed); and four patients were diagnosed with cochlear fibrosis (five ears) by MR hydrography, while four were diagnosed by CT (four ears). The correct rate of diagnosis was 77.40% (113/146) based on CT, while the rate was 93.84% (137/146) based on MR hydrography. CONCLUSIONS MR hydrography imaging technique can be applied to the preoperative evaluation of cochlear implantation, providing accurate and reliable anatomic information on the inner membranous labyrinth and nerves in the internal acoustic canal and an accurate basis for the diagnosis of cochlear fibrosis and nerve development. This has a guiding significance for the selection of treatment schemes.

Maxillofacial Rosai-Dorfman′s disease: a case report and literature review / 口腔疾病防治

Objective@#To explore the clinical manifestations, histopathological features, diagnosis, treatment and prognosis of Rosai-Dorfman′s disease (RDD) in the maxillofacial region and to review the relevant literature in order to improve the understanding, diagnosis and treatment of oral and maxillofacial RDD.@*Methods @#The clinical manifestations, histopathological features, diagnosis, treatment, and prognosis of a patient with RDD in the maxillofacial region admitted to Shenzhen People′s Hospital were analyzed, and the literature was reviewed for analysis. @*Results@#The clinical manifestations were palpable masses of 3.5 cm × 2.0 cm × 1.0 cm in the right cheek and 3.0 cm × 2.0 cm × 1.0 cm in the right submaxillary area, with clear boundaries, good mobility, medium and hard textures, respectively, no tenderness, smooth surfaces, and no obvious nodules. On contrast-enhanced and plain CT scans of the maxilla and neck, a diffuse soft tissue shadow was seen in the right maxillofacial region with an unclear boundary and uniform density, and the contrast-enhanced scan also showed moderate and uniform enhancement. The primary diagnosis was right maxillofacial lesions. The tumor was resected surgically. The pathological report was right buccal and right submaxillary extranodal RDD. Under light microscopy, nodular lesions in the fibrous fat tissue were found, which were composed of light and deep staining areas. The light staining areas consisted of patchy, polygonal cells with large volumes and rich cytoplasm, in which lymphocytes and neutrophils could be seen stretching into the movement; the deep staining areas were composed of lymphocytes and plasma cells. IHC: S-100 (+), CD68 (+), CD163 (+), CD1a (-), CD21FDC (+), langerin (-), IgG (+), IgG4 (+). No recurrence was found 11 months after the operation. RDD is a rare, benign and self-limited tissue and cell disease and consists of multiple lesions in the maxillofacial region. Its imaging features are similar to those of lymphoma. Its pathological features are large volumes, rich cytoplasm and phagocytosis of lymphocytes and plasma cells. Generally, RDD only needs to be observed, and individuals with symptoms or the involvement of important organs need to be treated; the first choice for the extranodal type is drug treatment, with radiotherapy administered if the central nervous system is involved. Surgery is recommended if involvement of important organs and compression of the trachea are observed; chemotherapy should be used for diffuse RDD. Most patients with RDD experienced relapse or remission of the disease; a few patients died because of the involvement of important organs or complications.@*Conclusion @#The clinical manifestations of maxillofacial RDD vary and lack specific imaging features, and pathological immunohistochemistry is the gold standard for diagnosis. The etiology is not completely clear, the treatment methods are varied, and the prognosis is related to the involved range of the disease.

Tumor size (hazard ratio = 1.826; 95% CI = 1.131–2.947; P = 0.014) was considered as independent prognostic factors of long-term survival. Conclusion: Percutaneous thermal ablation combined with simultaneous TACE is a safe and effective treatment for HCC ≤ 5 cm.

Associations of Non-alcoholic Fatty Liver Disease with Prevalence,Severity,and Prognosis of Coronary Heart Disease / 中国医学科学院学报

Objective To explore the associations of non-alcoholic fatty liver disease(NAFLD)with the prevalence,severity,and prognosis of coronary heart disease(CHD). Methods A total of 512 hospitalized patients undergoing coronary angiography in our department from June 2013 to June 2015 were enrolled.Fatty liver was judged by ultrasound screening,and Gensini score was calculated according to the result of coronary angiography.Then the independent predictors of CHD were analyzed.The association between NAFLD and cardiovascular endpoints was analyzed during prospective follow-up among 276 CHD patients. Results The CHD prevalence was 76.8% in NAFLD group and 50.7% in non-NAFLD group(P=0.000),the number of target vessels was 2(1,3)and 1(1,3)(P=0.019),and the Gensini score was(29.02±27.62)and(24.04±20.18)(P=0.022),respectively.NAFLD was an independent predictor of CHD(OR=2.28,95%CI=1.54-3.56,P0.1).Cox regression analysis showed that NAFLD was not a predictor of cardiovascular endpoints in patients with CHD(HR=0.95,95%CI=0.62-1.58,P=0.691).Conclusion NAFLD is an independent predictor of CHD,and it is related to severity of coronary artery stenosis.However,it can not predict the clinical outcomes of patients with CHD.

Comparison of diagnostic efficacy between transrectal and transperineal prostate biopsy: A propensity score-matched study / 亚洲男科学杂志(英文版)

This study compared the diagnostic efficacy of transrectal ultrasound (TRUS)-guided prostate biopsy (TRBx) and transperineal prostate biopsy (TPBx) in patients with suspected prostate cancer (PCa). We enrolled 2962 men who underwent transrectal (n = 1216) or transperineal (n = 1746) systematic 12-core prostate biopsy. Clinical data including age, prostate-specific antigen (PSA) level, and prostate volume (PV) were recorded. To minimize confounding, we performed propensity score-matching analysis. We measured and compared PCa detection rates between TRBx and TPBx, which were stratified by clinical characteristics and Gleason scores. The effects of clinical characteristics on PCa detection rate were assessed by logistic regression. For all patients, TPBx detected a higher proportion of clinically significant PCa (P - 80 years (80.4% vs 56.5%, P = 0.004) and with PSA level 20.1-100.0 ng ml-1 (80.8% vs 69.1%, P = 0.040). In conclusion, TPBx was associated with a higher detection rate of clinically significant PCa than TRBx was; however, because of the high detection rate at certain ages and PSA levels, biopsy approaches should be optimized according to patents' clinical characteristics.

Comparison of diagnostic efficacy between transrectal and transperineal prostate biopsy: A propensity score-matched study / 亚洲男科学杂志(英文版)

This study compared the diagnostic efficacy of transrectal ultrasound (TRUS)-guided prostate biopsy (TRBx) and transperineal prostate biopsy (TPBx) in patients with suspected prostate cancer (PCa). We enrolled 2962 men who underwent transrectal (n = 1216) or transperineal (n = 1746) systematic 12-core prostate biopsy. Clinical data including age, prostate-specific antigen (PSA) level, and prostate volume (PV) were recorded. To minimize confounding, we performed propensity score-matching analysis. We measured and compared PCa detection rates between TRBx and TPBx, which were stratified by clinical characteristics and Gleason scores. The effects of clinical characteristics on PCa detection rate were assessed by logistic regression. For all patients, TPBx detected a higher proportion of clinically significant PCa (P < 0.001). Logistic regression analyses illustrated that PV had a smaller impact on PCa detection rate of TPBx compared with TRBx. Propensity score-matching analysis showed that the detection rates in TRBx were higher than those in TPBx for patients aged >- 80 years (80.4% vs 56.5%, P = 0.004) and with PSA level 20.1-100.0 ng ml-1 (80.8% vs 69.1%, P = 0.040). In conclusion, TPBx was associated with a higher detection rate of clinically significant PCa than TRBx was; however, because of the high detection rate at certain ages and PSA levels, biopsy approaches should be optimized according to patents' clinical characteristics.
