CCTA-Derived Fat Attenuation Index Predict Future Percutaneous Coronary Intervention.

OBJECTIVES: This study aims to investigate the differences in plaque characteristics and fat attenuation index (FAI) between in patients who received revascularization versus those who did not receive revascularization and examine whether the machine-learning (ML) based model constructed by plaque characteristics and FAI can predict revascularization. MATERIALS & METHODS: This study was a post hoc analysis of a prospective single-center registry of sequential patients undergoing CCTA, referred from inpatient and emergency department settings (n = 261, 63 years ± 8; 188 men). The primary outcome was revascularization by percutaneous coronary revascularization. The CTA images were analyzed by experienced radiologists using a dedicated workstation in a blinded fashion. The ML-based model was automatically computed. RESULTS: The study cohort consisted of 261 subjects. Revascularization was performed in 105 subjects. Patients receiving revascularization had higher FAI value (67.35±5.49 Hu vs -80.10±7.75 Hu, p < 0.001) as well as higher plaque length, calcified, lipid and fibrous plaque burden and volume. When FAI was incorporated into a ML risk model based on plaque characteristics to predict revascularization, the area under the curve increased from 0.84 (95% CI: 0.68-0.99) to 0.95 (95% CI: 0.88-1.00). CONCLUSION: ML-algorithms based on FAI and characteristics could help improve the prediction of future revascularization and identify patients likely to receive revascularization. ADVANCES IN KNOWLEDGE: Pre-procedural FAI could help guide revascularization in symptomatic CAD patients.

A nomogram for predicting the overall survival in rectal cancer patients after total neoadjuvant therapy.

BACKGROUND: Total neoadjuvant therapy (TNT) has been recommended by the National Comprehensive Cancer Network for treating locally advanced rectal cancer (LARC), but extremely rare studies have focused on establishing nomograms to predict the prognosis in these patients after TNT. We aimed to develop a nomogram to predict overall survival (OS) in rectal cancer patients who underwent TNT. METHODS: In retrospective cohort study, we extract the data of the rectal cancer patients from the SEER database between 2010 and 2015, including demographic information and tumor characteristics. The cohort was divided into training set and validation set based on a ratio of 7:3. Univariate logistic regression analysis was utilized for the comparison of variables in training set. Candidate variables with P < 0.1 in training set was entered into the best subset selection, LASSO regression and Boruta feature selection. Finally, the selected variables significantly associated with the 3-year, 5-year, and 8-year OS were used to build a nomogram, followed by validation using receiver operating characteristic (ROC) curve, area under the curve (AUC), and calibration curve. RESULTS: A total of 3265 rectal cancer patients (training set: 2285; test set: 980) were included in the present study. A nomogram was developed to predict the 3-year, 5-year, and 8-year OS based on age, household income, total number of in situ/malignant tumors, CEA, T stage, N stage and perineural invasion. The nomogram showed good efficiency in predicting the 3-year, 5-year and 8-year OS with good AUC for the training set and test set, respectively. CONCLUSION: We established a nomogram for predicting the 3-year, 5-year, and 8-year OS of the rectal cancer patients, which showed good prediction efficiency for the OS after TNT.

[A multicenter study on the effects of congenital cytomegalovirus infection on hearing loss].

Objective: To assess the clinical features and effectiveness of antiviral therapy in newborns with sensorineural hearing loss (SNHL) caused by congenital congenital cytomegalovirus (cCMV) infection, and to speculate the risk factors for poor hearing outcomes. Methods: A multicenter prospective cohort study wasconducted, enrolling 176 newborns diagnosed with cCMV at four research centers in Zhejiang Province from March 1, 2021, to April 30, 2024. Clinical characteristics at birth were recorded and hearing was followed up. The children were divided into groups based on their condition at birth, specifically into asymptomatic, mild symptom, and moderate to severe symptom groups. Additionally, they were divided into SNHL and normal hearing groups based on the results of air conduction brainstem audiometry at birth. And they were also divided into treatment and untreated groups according to antiviral treatment. Mann Whitney U test, and chi square test were used for inter group comparison to analyze the differences in clinical features between different disease groups, and to analyze the effects of clinical features, antiviral therapy, and other factors on hearing improvement. Logistic regression analysis was employed to identify the risk factors influencing hearing outcomes. Results: Among the cohort of 176 children diagnosed infection with cCMV, 90 cases were male and 86 cases were female. Of these, 79 cases were asymptomatic, 12 cases classified as mild cCMV and 85 cases as moderate to severe cCMV. Fifty cases belonged to SNHL group, with different degrees of severity, including 30 cases of mild, 9 cases of moderate, 5 cases of severe, and 6 cases of extremely severe SNHL. Among the 121 cases in the normal hearing group, 2 cases (1.7%) exhibited late-onset hearing loss despite having normal hearing at birth. Among 81 cases (46.0%) who completed the hearing follow-up, 71 cases (87.7%) had good hearing outcomes and 10 cases (12.3%) had poor hearing outcomes. Among the 81 children, 29 cases (35.8%) had SNHL at birth. During follow-up, the hearing threshold improved in 19 cases (65.5%), remained stable in 7 cases (24.1%) and progressed in 3 cases (10.3%). A total of 26 cases in the treatment group and 55 cases in the untreated group completed the hearing follow-up assessment. The rate of hearing improvement in the treatment group was found to be higher compared to the untreated group (13 cases (50.0%) vs. 6 cases (10.9%), χ2=15.00, P<0.01), with individuals in the treatment group having a 4.58 times greater likelihood of experiencing hearing improvement (RR=4.58,95%CI 1.96-10.70, P<0.05). However, no statistically significant difference was observed in hearing outcomes between the antiviral treatment group and the untreated group (RR=0.90, 95%CI 0.57-1.41, P=0.517). Multivariate analysis further confirmed SNHL (OR=11.58, 95%CI 2.10-63.93, P=0.005) and preterm birth (OR=4.98, 95%CI 1.06-23.41, P=0.042) as independent risk factors for poor hearing outcomes. Conclusions: SNHL resulting from cCMV infection presents symptoms at birth and can be improved by antiviral therapy. Poor hearing outcomes are associated with SNHL and prematurity.

The gene CmPYL6 strongly contributes to cold tolerance in oriental melon.

The current simple and crude facilities make melon production more susceptible to cold stress during off-season cultivation in China. The ABA signalling pathway is an important target for breeding cold-tolerant melon. Cold-tolerant No. 330 and cold-sensitive No. 410 oriental melon genotypes were used to analyse the relationship between ABA and cold tolerance. 12 CmPYLs, ABA receptors, were identified from the melon genome database according to sequence alignment and phylogenetic analysis. Gene function of CmPYL6 in cold tolerance was analysed using VIGS in No. 330 and overexpression in Arabidopsis WT. A total of 12 CmPYL members contain the representative domain and conserved sites. Under cold treatment, No.330 seedlings had lower electrolyte leakage and MDA content, higher ABA content and CmPYL6 expression than seedlings of No. 410. Exogenous application of ABA upregulated expression of CmPYL6 and enhanced cold tolerance of both genotypes, while inhibiting ABA accumulation reduced expression of CmPYL6 and cold tolerance of both genotypes. CmPYL6-silenced No. 330 seedlings had reduced cold tolerance, increased electrolyte leakage and MDA content as well as limited proline and soluble sugar content, while CmPYL6 overexpressed transgenic Arabidopsis plants had enhanced cold tolerance, with limited electrolyte leakage and MDA content, as well as increased proline and soluble sugar content. The CmPYL6 gene is probably an important ABA receptor in regulating cold tolerance of oriental melon. Our study provides a direction for improving breeding of cold tolerance of oriental melon.

[An analysis of related factors in thrombocytopenia combined with cirrhosis: a cross-sectional study of 2 517 cases].

Objective: To explore the related factors of thrombocytopenia (TCP) occurrence in patients with cirrhosis. Methods: A cross-sectional study was conducted. Inpatients with an initial diagnosis of cirrhosis at Peking University First Hospital from January 1, 2010 to December 31, 2020 were included. Clinical data such as demographic characteristics, etiology of cirrhosis, complications of cirrhosis, laboratory indicators, Child-Pugh grade, invasive procedures, and mortality during hospitalization were collected. A logistic regression model was used to explore the related factors of TCP occurrence in patients with cirrhosis. Categorical variables were compared by the χ(2) test. The inter-group comparison was performed using continuous variables, a t-test, one-way analysis of variance (ANOVA), or a nonparametric test. Results: There were a total of 2 592 cases of cirrhosis. 75 cases with incomplete clinical data were excluded. 2 517 cases were included for analysis. The median age was 58 (50, 67) years. Males accounted for 64%. 1 435 cases (57.0%) developed TCP, and 434 cases (17.2%) had grade 3-4 TCP. Gender, primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), and concomitant esophagogastric varices (EGV) were the major factors associated with TCP. Females were more prone to combine with TCP (OR=1.32, 95%CI: 1.12-1.56, P=0.001). Patients combined with EGV (OR=3.09, 95%CI: 2.63-3.65, P<0.001) were more prone to develop TCP, which was associated with the increased incidence of hypersplenism (P<0.001). Patients with PBC (OR=0.64, 95%CI: 0.50-0.82, P<0.001) and PSC (OR=0.23, 95%CI: 0.06-0.65, P=0.010) were less prone to develop TCP, which was due to the shorter prothrombin time and better coagulation function of PBC patients (P<0.001), and the lower proportion of hypersplenism in combined PSC patients (P=0.004). Patients with TCP and grade 3-4 TCP had a higher rate of hemostatic procedures (P<0.05), but a lower rate of liver biopsy (P<0.05). Patients with grade 3-4 TCP had a higher nosocomial mortality rate compared to those without (P=0.004). Conclusion: TCP is common in patients with cirrhosis. However, TCP occurrence is higher in female patients with EGV and lower in patients combined with PBC and PSC. TCP affects invasive procedures and is associated with adverse outcomes.

[Advances in the application of minimal residual disease in non-metastatic colorectal cancer].

In recent years, the application of minimal residual disease (MRD) in solid tumors has gained widespread attention. MRD typically refers to the presence of residual cancer cells that remain undetectable by imaging after curative treatments, such as surgical resection. The presence of MRD post-surgery is significantly associated with an increased risk of tumor recurrence. In colorectal cancer, circulating tumor DNA (ctDNA) serves as an effective marker for assessing MRD, particularly in non-metastatic (stages I-III) colorectal cancer. As a real-time, accurate, and convenient biomarker, ctDNA can effectively predict tumor recurrence, guide postoperative adjuvant chemotherapy decisions, and provide crucial information for recurrence monitoring. The application prospects of ctDNA detection technology are vast, promising more precise and individualized treatment plans for colorectal cancer patients. This article comprehensively analyzes the progress in the application of ctDNA for detecting MRD in non-metastatic colorectal cancer patients, elaborates on its guiding role in clinical treatment decisions, and envisions the future development directions in this field.

[Analysis of the efficacy and safety of hepatic arterial infusion chemotherapy for unresectable hepatitis B-related intrahepatic cholangiocarcinoma].

Objective: To explore the efficacy and safety of hepatic arterial infusion chemotherapy(HAIC) for unresectable hepatitis B-related intrahepatic cholangiocarcinoma(ICC). Methods: This is a retrospective controlled study. Data from 140 unresectable ICC patients who received HAIC treatment at Sun Yat-sen University Cancer Center from March 2015 to June 2023 were retrospectively collected, including 72 patients in the hepatitis B surface antigen(HBsAg)negative group (43 males and 29 females, aged (59.6±9.5)years(range: 34 to 81 years)), 68 cases in the HBsAg-positive group (48 males, 20 females, aged (53.4±11.4)years(range: 29 to 82 years)). HAIC treatment used the FOLFOX regimen combined with oxaliplatin, leucovorin,and fluorouracil. The differences in effects, prognosis,and adverse reactions between the two groups of patients after HAIC treatment were analyzed. All variables were expressed as categorical data. The χ2 test or Fisher's exact probability method was used to compare between groups. The Kaplan-Meier method was used to draw survival curves. The difference of survival curve between groups were compared through the Log-rank test. Results: According to the Response Evaluation Criteria in Solid Tumors(RECIST) version 1.1,the objective response rate(ORR) of the HBsAg-negative group was 23.2%(16/69),and the ORR of the HBsAg-positive group was 40.3%(25/62). The difference in ORR between the two groups was statistically significant(χ2=4.459,P=0.035). According to the modified RECIST(mRECIST) criteria,the ORR of the HBsAg-negative group was 27.5%(19/69), and the ORR of the HBsAg-positive group was 45.2%(28/62). The difference in ORR between the two groups was statistically significant(χ2=4.410,P=0.036). The median progression-free survival(PFS) of the HBsAg-negative group and the positive group were 7.1 months(95%CI: 5.8 to 13.2 months) and 7.3 months (95%CI: 5.7 to 10.3 months), respectively, and the median overall survival(OS) were 16.3 months (95%CI: 12.5 to 33.9 months) and 15.9 months (95%CI: 9.2 to 20.7 months) respectively. There were no statistically significant differences in PFS and OS between the two groups (both P>0.05). The main serious adverse reactions of the two groups of patients included increased AST, increased ALT, thrombocytopenia,and neutropenia. There were no statistically significant differences in various adverse reactions between the two groups after HAIC treatment (all P>0.05). Conclusion: Patients with HBsAg-positive unresectable ICC are more likely to benefit from HAIC treatment.

First molecular identification and phylogenetic illustration of Sarcocystis species infection in Red Sea shortfin mako shark (Isurus oxyrinchus Rafinesque, 1810).

BACKGROUND: members of the genus Sarcocystis are intracellular obligate protozoan parasites classified within the phylum Apicomplexa and have an obligate heteroxenous life cycle involving two hosts. A more comprehensive understanding of the prevalence and geographic range of different Sarcocystis species in marine ecosystems is needed globally and nationally. Hence, the objective of this study was to document the incidence of Sarcocystis infection in sharks within the aquarium ecosystem of Egypt and to identify the species through the characterization of the SSU rDNA gene. METHODS: All organs of the mako shark specimen underwent macroscopic screening to detect the existence of a Sarcocystis cyst. Ten cysts were collected from the intestine and processed separately to extract the genomic DNA. The polymerase chain reaction (PCR) was accomplished by amplifying a specific 18S ribosomal RNA (rRNA) gene fragment. Subsequently, the resulting amplicons were subjected to purification and sequencing processes. RESULTS: Macroscopic examination of the mako shark intestinal wall sample revealed the presence of Sarcocystis cysts of various sizes and shapes, and sequencing of the amplicons from Sarcocystis DNA revealed a 100% nucleotide identity with the sequence of Sarcocystis tenella recorded from sheep in Iran; The mako shark sequence has been deposited in the GeneBank with the accession number OQ721979. This study presents the first scientific evidence demonstrating the presence of the Sarcocystis parasite in sharks, thereby documenting this specific marine species as a novel intermediate host in the Sarcocystis life cycle. CONCLUSIONS: This is the first identification of Sarcocystis infection in sharks, and we anticipate it will be an essential study for future screenings and establishing effective management measures for this disease in aquatic ecosystems.

Association of the triglyceride-glucose index variability with blood pressure and hypertension: a cohort study.

BACKGROUND: Several studies have indicated that the triglyceride-glucose index (TyG) index is associated with hypertension; however, evidence on the association of change in the TyG index with blood pressure and hypertension is limited. AIMS: To assess the association of the TyG index with blood pressure and hypertension. DESIGN: A cohort study. METHODS: We included 17 977 individuals with a mean age of 60.5 years from the Dongfeng-Tongji cohort. The TyG index was calculated as ln [fasting triglyceride (mg/dl)×fasting glucose (mg/dl)/2]. Hypertension was defined as blood pressure ≥140/90 mmHg, self-reported current use of antihypertensive medication or self-reported physician diagnosis of hypertension. RESULTS: In the longitudinal analyses, we found a linear dose-response relationship between changes in the TyG index and change in blood pressure. Each one-unit change in the TyG index was associated with a 1.93 (1.23-2.63) mmHg increase in systolic blood pressure (SBP) and a 1.78 (1.42-2.16) mmHg increase in diastolic blood pressure (DBP). During a median follow-up of 9.37 years, a total of 3594 individuals were newly diagnosed with hypertension. We also found a linear dose-response relationship between the TyG index and the incidence of hypertension. The hazard ratio (HR) of hypertension for each one-unit increase in the TyG index was 1.21 (1.13-1.29). In addition, the best cut-off point of TyG for predicting hypertension was 8.4797, with sensitivity, and specificity of 57.85% and 55.40%, respectively. CONCLUSIONS: The TyG index had a positive dose-response relationship with blood pressure and could be used to predict the risk of hypertension.

Correlation study between bone metabolic markers, bone mineral density, and sarcopenia.

OBJECTIVE: To investigate the correlation between bone metabolism markers, bone mineral density (BMD), and sarcopenia. METHODS: A total of 331 consecutive patients aged ≥ 60 years who were hospitalized between November 2020 and December 2021 were enrolled. Participants were divided into sarcopenia and non-sarcopenia groups according to the Asian Working Group on Sarcopenia criteria (AWGS, 2019). The clinical data, bone metabolism markers (ß-CTX, N-MID, and TP1NP), and BMD were compared between the two groups. RESULTS: Age, ß-CTX, and N-MID of the sarcopenia group were higher than those of the non-sarcopenia group (P < 0.05), but the BMD T values were lower than those of the non-sarcopenia group (P < 0.05). Binary logistic regression analysis showed that increased femoral neck BMD (FNBMD) was a protective factor for sarcopenia, while increased ß-CTX was a risk factor. Pearson/Spearman correlation analysis showed that the diagnostic indices of sarcopenia were positively correlated with FNBMD and negatively correlated with ß-CTX and N-MID. Multiple linear regression analysis revealed that BMI and FNBMD significantly positively affected muscle strength and appendicular skeletal muscle mass (ASM). The FNBMD significantly positively affected physical performance, while ß-CTX significantly negatively affected muscle strength, ASM, and physical performance. CONCLUSION: Increased FNBMD may be a protective factor against sarcopenia, and increased ß-CTX may be a risk factor. The FNBMD significantly positively affected the diagnostic indices of sarcopenia, while ß-CTX significantly negatively affected them. BMD and bone metabolism marker levels may be considered in early screening for sarcopenia.

Acromegaly presented with acne vulgaris: a retrospective study with 123 cases.

BACKGROUND: Acne vulgaris is a prevalent skin condition. We have found that some acromegaly patients have acne. However, no study has examined the relationship between acromegaly and acne. OBJECTIVE: To explore prevalence and correlation of adult acne in patients with acromegaly. METHODS: For this cross-sectional study, we collected questionnaires, clinical information, and laboratory test results of acromegaly patients from January 2022 to December 2022 at Huashan Hospital. Of the 133 questionnaires returned, 123 had valid responses. RESULTS: Of the 123 patients with acromegaly enrolled in this study, 54.5% had adult acne. No statistically significant difference was found in prevalence between male and female patients. 61.2% of adult acne patients reported late-onset acne. Late-onset acne patients first developed acne years before acromegaly diagnosis (mean of 5.6 years for male and 4.5 years for female patients). Some acne patients have received traditional anti-acne treatment. Moreover, 31% of the patients reported no improvement, and only 3.5% of patients claimed complete resolution of acne after treatment. Before acromegaly treatment, the prevalence of adult acne was 51.2%, with mild acne accounting for 73.0%, moderate acne accounting for 23.8%, and severe acne accounting for 3.2%. After acromegaly treatment, the prevalence of adult acne was significantly decreased to 37.4% (P = 0.007). An overall decrease in acne severity was noted, with 93.5%, 6.5%, and 0% having mild, moderate, and severe acne, respectively. A total of 83.6% of the patients had self-assessed acne remission, and 33.3% of the patients reported complete acne resolution. However, 9.0% of patients reported that their condition had worsened after acromegaly treatment. After treatment, GH, IGF-1, IGF-1 index, insulin levels, and HOMA-IR decreased significantly in all patients with acromegaly (P < 0.05). Acne remission correlated positively with IGF-1 levels, but not with GH levels. The relationship between acromegaly and acne remains to be elucidated. CONCLUSIONS: Our findings provide preliminary evidence of the high prevalence of adult acne in acromegaly patients, and a high rate of late-onset acne as well. Traditional anti-acne treatments are less effective. Acne could be considerably relieved by treating acromegaly. Acne remission positively correlated with IGF-1 decline as well, which revealed the correlation between acne and IGF-1.

Application of optimized LSTM in prediction of the cumulative confirmed cases of COVID-19.

This paper proposes an optimized Long Short-Term Memory (LSTM+) model for predicting cumulative confirmed cases of COVID-19 in Germany, the UK, Italy, and Japan. The LSTM+ model incorporates two key optimizations: (1) fine-adjustment of parameters and (2) a 're-prediction' process that utilizes the latest prediction results from the previous iteration. The performance of the LSTM+ model is evaluated and compared with that of Backpropagation (BP) and traditional LSTM models. The results demonstrate that the LSTM+ model significantly outperforms both BP and LSTM models, achieving a Mean Absolute Percentage Error (MAPE) of less than 0.6%. Additionally, two illustrative examples employing the LSTM+ model further validate its general applicability and practical performance for predicting cumulative confirmed COVID-19 cases.

[Traditional Chinese medicine may reduce the risk of readmission in patients with rheumatoid arthritis complicated with elevated platelet count: a matched cohort study].

OBJECTIVE: To evaluate the association of traditional Chinese medicine (TCM) treatment with the risk of readmission in patients with rheumatoid arthritis (RA) complicated with elevated platelet count. METHODS: We retrospectively collected the data of inpatients diagnosed with RA in our hospital from 2013 to 2021. The patients with elevated platelet count receiving TCM treatment were matched to those without TCM treatment using propensity score matching at the 1∶1 ratio, and the confounding factors were adjusted including gender, age, Chinese patent medicine, and external application. A Cox proportional hazard model was used to evaluate the hazard ratio (HR) of the risk of readmission, and a Kaplan-Meier curve was generated to assess the incidence of readmission in these patients. RESULTS: A total of 1176 RA patients with elevated platelet count were included in this study, including 842 patients in the TCM group and 334 patients in the non-TCM group, and after 1∶1 propensity score matching, 334 patients were included in each group. The Cox proportional hazards model showed that the readmission rate was significantly lower in TCM group than in non-TCM group (HR=0.59, 95% CI: 0.48-0.73, P<0.001), and TCM was a protective factor against readmission in RA patients with elevated platelet count. Kaplan-Meier curves demonstrated that long-term use of TCM helped to decrease the risk of readmission (Log-rank P<0.001). Association rules showed that the use of several Chinese herbal medicines and the Chinese patent medicine Xinfeng Capsule had a strong correlation with improvement of such clinical indicators as rheumatoid factor, erythrocyte sedimentation rate, and C-reactive protein. CONCLUSION: In RA patients with elevated platelet count, the use of TCM, as a protective factor against readmission, is strongly associated with a lowered risk of readmission with a long-term association.

Hyperbaric oxygen ameliorates neuronal injury and neurological function recovery in rats with intracerebral hemorrhage by silencing microRNA-204-5p-targeted chloride channel protein 3.

Hyperbaric oxygen (HBO) therapy is of clinical utility in patients with transient cerebral ischemia. The investigatory study was to identify the potential regulatory mechanism of HBO treatment on neuronal injury and neurological function recovery in rats with intracerebral hemorrhage (ICH). Firstly, the rat model of ICH was established by collagenase, and the experimental rats were treated with HBO at 2.5 absolute atmospheres for 60 min each time. Next, lentivirus interfering with microRNA (miR)-204-5p or chloride channel protein 3 (CLCN3) expression was injected via the tail vein. Afterward, neurological function assessment was conducted, serum S100ß and NSE contents were detected by enzymer-linked immunosorbent assay, and pathological conditions of brain tissue were observed by hematoxylin-eosin staining. Terminal deoxynucleotidyl transferase mediated dUTP nick end labeling staining was used to detect neuronal apoptosis. The results showed that HBO alleviated neuronal injury and neurological function recovery in ICH rats and reduced serum S100ß and NSE content (all P<0.05). At the same time, overexpressing miR-204-5p or depleting CLCN3 further promoted the therapeutic effect of HBO on ICH rats (all P<0.05), while silencing miR-204-5p or elevating CLCN3 did oppositely (all P<0.05). In conclusion, HBO alleviates neuronal injury and neurological function recovery in ICH rats by silencing miR-204-5p-targeted CLCN3.

[Epidemiological trend of early-onset gastric cancer and late-onset gastric cancer in China from 2000 to 2019].

Objective: In order to understand the changing trends of gastric cancer incidence and mortality in early-onset and late-onset in China from 2000 to 2019. Methods: The Global Burden of Disease research data was collected, and Excel and R 4.2.1 softwares were used to examine the incidence rate, mortality rate, and disability-adjusted life years (DALY) of Chinese people from 2000 to 2019, with a focus on gender, age, and year. Results: In 2019, the crude incidence rates were 7.06/100 000 (95%UI: 6.63/100 000-7.59/100 000) and 114.52/100 000 (95%UI: 108.79/100 000-121.63/100 000) for early- and late-onset gastric cancer, respectively. The crude mortality rate for early-onset gastric cancer was 3.29/100 000 (95%UI: 3.11/100 000- 3.50/100 000), while the crude mortality rate for late-onset gastric cancer was 81.88/100 000 (95%UI: 78.15/100 000-86.04/100 000). Additionally, the crude DALY rates for these two types of gastric cancer were 156.48/100 000 (95%UI: 148.82/100 000-165.84/100 000) and 1 750.13/100 000 (95%UI: 1 661.21/100 000-1 852.99/100 000). The standardized incidence of early-onset gastric cancer decreased from 5.49/100 000 in 2000 to 4.76/100 000 in 2019, and that of late-onset gastric cancer decreased from 143.45/100 000 in 2000 to 123.02/100 000 in 2019.The standardized mortality rate of early-onset gastric cancer decreased from 4.16/100 000 in 2000 to 2.18/100 000 in 2019, and that of late-onset gastric cancer decreased from 140.82/100 000 in 2000 to 91.49/100 000 in 2019. The standardized DALY rate for early-onset gastric cancer in 2019 was 105.87/100 000 (95%UI: 87.98/100 000 -125.60/100 000), lower than 198.84/100 000 (95%UI: 179.47/100 000- 219.83/100 000) in 2000. The standardized DALY rate for late onset gastric cancer in 2019 was 1 821.11/100 000 (95%UI: 1 509.42/100 000-2 158.53/100 000), lower than 2 932.52/100 000 (95%UI: 2 665.92/100 000-3 252.60/100 000) in 2000. Conclusions: The standardized mortality rate of early-onset gastric cancer in China showed a decreasing trend from 2000 to 2019. The standardized mortality rate of late onset gastric cancer showed a trend of first increasing and then decreasing. Notably, the incidence, mortality, and DALY of late-onset gastric cancer were significantly higher than those of early-onset gastric cancer during this period. Additionally, male incidence, mortality, and crude DALY rates were higher than female.

[Expert consensus on the biobank development of oral genetic diseases and rare diseases and storage codes of related biological samples from craniofacial and oral region].

The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.

[Two novel and de novo KMT2D mutations on the same allele cause Kabuki syndrome].

Objective: To screen the candidate genes in a patient with Kabuki syndrome (KS), providing basis for genetic counseling, prenatal screening, prenatal diagnosis and facilitating early treatment. Methods: This study included a 16-year-old female KS patient born of non-consanguineous Chinese parents who presented to Department of Orthognathic & Cleft Lip and Palate Plastic Surgery, School and Hospital of Stomatology, Wuhan University. Genomic DNA was extracted from the peripheral blood of the subjects and analyzed by whole-exome sequencing (WES). Sanger sequencing was performed to validate the mutation in the candidate gene. The conformational and physicochemical changes of the mutant were analyzed by Alphafold2, Antheprot and DOG.2.0.1, respectively. Distribution of KMT2D mutations in patients with KS was analyzed based on the Human Gene Mutation Database Results: The proband manifested a typical KS facial gestalt, congenital cleft palate, fifth finger deformity, hypodontia, renal hypoplasia and hydronephrosis. Two de novo mutations c.[1166A>C; 1167dupC] (NM_003482) in cis on the same allele in the KMT2D gene were identified by WES and confirmed by allele-specific PCR. Bioinformatics analysis showed that three more α-helixes were added, and a (ß-) turn and a (ß-) sheet were reduced in KMT2D p. Y389S, p.V390Rfs*26 compared with the wild type. Meanwhile, the interceptive mutant-KMT2D protein p.V390Rfs*26 lost all four domains (FYRN domain, FYRC domain, SET domain, and PostSET domain), which may cause functional disabilities. Conclusions: Our study is the first to identify two novel and de novo KMT2D mutations in cis on the same allele in a KS patient and extends the KMT2D mutation spectrum of KS, providing evidence for genetic susceptibility counseling, prenatal screening and diagnosis, and early treatment of KS.

[Effects of macrophage glycolytic reprogramming on tuberculosis granuloma formation].

The formation of granulomatous lesions is a typical pathological feature of tuberculosis, and infection with Mycobacterium tuberculosis is the main cause. Although the mechanism underlying granuloma formation remains unclear, increasing evidence suggests that immune metabolism plays an important role. In this review, we summarized the latest advances in macrophage glycolytic reprogramming in tuberculosis granuloma formation to discover new methods for early diagnosis and provided new ideas for tuberculosis therapeutics based on the regulation of immune metabolism.
