ObjectiveThis paper aims to investigate and evaluate the staged efficacy and safety of the representative empirical prescription of the “Zhu Ke Jiao” theory， Qijia Rougan prescription， combined with entecavir in the treatment of hepatic fibrosis in chronic hepatitis B. MethodsA multicenter randomized controlled clinical study was conducted， and 101 patients diagnosed with chronic hepatitis B-related hepatic fibrosis （CHB-HF） who met the diagnosis and inclusion criteria were randomly assigned to an observation group （Qijia Rougan prescription + entecavir） and a control group （entecavir）. The treatment duration was 24 weeks. Liver stiffness measurement （LSM）， fibrosis-4 index （FIB-4）， portal vein diameter， hepatitis B serology， biochemical indicators， hepatic fibrosis markers in serum ［hyaluronic acid （HA）， laminin （LN）， procollagen Ⅲ peptide （PⅢP）， and type Ⅳ collagen （Ⅳ-C）］， and traditional Chinese medicine syndrome scores were used as efficacy evaluation indicators. Efficacy assessments and explorations of different staged subgroups of Qijia Rougan prescription were conducted according to LSM values based on the Metavir pathological staging standard. ResultsA total of 98 cases were included for statistical analysis， with 49 cases in the observation group and 49 in the control group. The general data of the patients in both groups were comparable. Compared with the same group before treatment， the observation group showed a significant reduction in LSM and FIB-4 （P<0.01）， as well as notable improvements in LN， Ⅳ-C， and various TCM syndrome scores （P<0.05， P<0.01）. When compared to the control group after treatment， the observation group demonstrated significant improvements in LSM， FIB-4， and various TCM syndrome score indicators （P<0.05， P<0.01）， indicating that the observation group performed better than the control group. Subgroup analysis of the regression of hepatic fibrosis stages showed that compared to the same group before treatment， the observation group had better improvement in regression of stages F2 and F3 （P<0.05）. When compared to the control group after treatment， the observation group exhibited superior improvement in regression of stage F3 （P<0.05）. No adverse events occurred in either group during the treatment period. ConclusionCompared with entecavir alone， the combination of Qijia Rougan prescription and entecavir significantly improves the degree of hepatic fibrosis and clinical TCM symptoms in patients. The optimal intervention period is primarily during stage F3， which is a potential “interception” point of the “Zhu Ke Jiao” theory.

OBJECTIVE: To explore the genetic etiology for a pregnant woman with a history of multiple adverse pregnancies and assess the phenotype-genotype correlation of 22q11.2 microduplication syndrome in her family. METHODS: Amniotic fluid sample was taken from a pregnant woman for whom non-invasive prenatal screening indicated chromosome 22 abnormalities in the fetus. Peripheral blood samples from the woman, her brother and parents were collected for high-throughput low-depth whole genome sequencing (CNV-seq). A pedigree traceability analysis of the results was conducted in conjunction with analysis of clinical manifestation. Relevant literature (from establishment to March 2025) was systematically searched. This study was approved by the Medical Ethics Committee of Mianyang Maternal and Child Health Care Hospital (Ethics No.: Lun Shen [2024]009). RESULTS: CNV-seq revealed that the fetus had harbored a 6.02 Mb duplication at 22q11.21q11.23. Karyotyping confirmed it as 46,X?dup(22)(q11.2). Pedigree verification demonstrated that the pregnant woman, her brother and mother had all carried the same duplication. Phenotypic analysis of the affected family members showed classic features of 22q11.2 microduplication syndrome, including hypernasal speech, low nasal bridge, congenital heart disease, and cognitive impairment. A total of 44 cases with full information (including three patients from this pedigree) were included in the analysis. The penetrance of 22q11.2 duplication was approximately 29.5% (13/44), and 52.3% (23/44) of the cases had inherited the variant from a phenotypically normal parent. CONCLUSION This study has identified the genetic basis for the woman's recurrent adverse pregnancies and phenotypic abnormalities in her family members. The scoliosis identified in her younger brother has not been previously reported, thereby may enrich the clinical phenotype of this syndrome. For fetuses identified with a 22q11.2 microduplication, detailed fetal imaging is recommended, and genetic counseling should be provided to the couples.

BACKGROUND:The Twin-block orthodontic appliance is commonly used for the correction of Class Ⅱ malocclusion.Its mechanism of action in stimulating mandibular growth has been confirmed in many studies,but its impact on maxillary growth is not very clear. OBJECTIVE:By establishing a finite element model to analyze the stress distribution of the maxillary complex,surrounding bone sutures,and maxillary dentition in patients with Class Ⅱ malocclusion wearing Twin-block orthodontic appliances. METHODS:One patient with Class Ⅱ malocclusion who underwent orthodontic treatment at Qingdao Hospital/Qingdao Municipal Hospital of Shandong Rehabilitation University was selected.The bite force data of the patient when wearing the Twin-block orthodontic appliance was measured,and CBCT data were collected.A finite element model was established,including the maxillary complex,peripheral sutures,Twin-block orthodontic appliance,and maxillary dentition.ABAQUS software was used to simulate the stress distribution in the maxilla and maxillary dentition when the patient was wearing the Twin-block appliance. RESULTS AND CONCLUSION:The equivalent stress on the maxillary anterior teeth was significantly smaller than that on the posterior teeth,and the maximum equivalent stress on both sides of the teeth were 4.797 5 Mpa and 8.716 1 Mpa,respectively,which were located at the first premolar.The maximum displacements were presented at the maxillary incisors on both sides of the teeth,which were 0.080 5 mm and 0.081 0 mm,respectively.The maximum equivalent stress on the bone suture was 1.284 Mpa,which was mainly concentrated in the pterygopalatine suture and the frontal-maxillary suture on both sides,and there was almost no difference in the force of the rest of bone sutures;the maximum displacement of the bone suture was 0.07 mm,with the pterygopalatine suture having the largest displacement,followed by the frontal-maxillary suture.The maximal equivalent stress on the maxillary complex was 27.18 Mpa,which was mainly concentrated on both sides of the anterior pyriform foramen of the maxilla,around the nasofrontal suture and around the pterygopalatine suture at the posterior part of the jaws.The maximal displacement of the maxilla was 0.07 mm,which was mainly concentrated on the maxillary alveolar bone.All these findings show that the occlusal force acts on the maxillary complex through the Twin-block appliance,resulting in clockwise rotation of the maxilla and steepening of the dentition plane.Measures should be taken to compensate for this tendency,for example,by considering maxillary molar elongation and intrusion in the process of occlusion,which are not only able to flatten the occlusal plane,but facilitate the mandibular protraction,thereby further improving Class Ⅱ malocclusion orthodontic treatment.

Background: This study aimed to estimate temporal trends in metabolically unhealthy obesity (MUO) among United States (US) adults by age, sex, race/ethnicity, and income from 1999 to 2018. Methods: We included 17,230 non-pregnant adults from a nationally representative cross-sectional study, the National Health and Nutrition Examination Survey (NHANES). MUO was defined as body mass index ≥30 kg/m2 with any metabolic disorders in blood pressure, blood glucose, and blood lipids. The age-adjusted percentage of MUO was calculated, and linear regression models estimated trends in MUO. Results: The weighted mean age of adults was 47.28 years; 51.02% were male, 74.64% were non-Hispanic White. The age-adjusted percentage of MUO continuously increased in adults across all subgroups during 1999–2018, although with different magnitudes (all P<0.05 for linear trend). Adults aged 45 to 64 years consistently had higher percentages of MUO from 1999–2000 (34.25%; 95% confidence interval [CI], 25.85% to 42.66%) to 2017–2018 (42.03%; 95% CI, 35.09% to 48.97%) than the other two age subgroups (P<0.05 for group differences). The age-adjusted percentage of MUO was the highest among non-Hispanic Blacks while the lowest among non-Hispanic Whites in most cycles. Adults with high-income levels generally had lower MUO percentages from 1999–2000 (22.63%; 95% CI, 17.00% to 28.26%) to 2017–2018 (32.36%; 95% CI, 23.87% to 40.85%) compared with the other two subgroups. Conclusion This study detected a continuous linear increasing trend in MUO among US adults from 1999 to 2018. The persistence of disparities by age, race/ethnicity, and income is a cause for concern. This calls for implementing evidence-based, structural, and effective MUO prevention programs.

ObjectiveTo investigate the effects of ethoxysanguinarine （ETH） on angiotensin Ⅱ （Ang Ⅱ）-mediated cardiomyocyte apoptosis and its regulatory effects of inositol-requiring enzyme 1 （IRE1）/regulated IRE1-dependent decay （RIDD） signaling pathway and endoplasmic reticulum stress. MethodsWestern blot was used to detect the establishment of the H9c2 model via Ang Ⅱ stimulation， which was identified as a cardiomyocyte apoptosis model. Subsequently， the inhibitory effect of ETH on cell proliferation was assessed using the cell counting Kit-8 （CCK-8） to determine the optimal effective dose of ETH. H9c2 cardiomyocytes were divided into a blank group， a model group （Ang Ⅱ， 1 mmol·L^-1）， and low-， medium-， and high-dose ETH groups （1.25， 2.5， and 5 mmol·L^-1）. Morphological changes in cardiomyocytes induced by Ang Ⅱ were detected using phalloidin staining. Cardiomyocyte apoptosis was assessed using terminal deoxynucleotidyl transferase dUTP nick and labeling （TUNEL） staining. The apoptosis cycle was detected by Annexin V/PI flow cytometry. Western blot was used to detect the expression levels of apoptosis-related proteins， endoplasmic reticulum stress， and IRE1/RIDD pathway-related proteins. ResultsWestern blot results showed that 1 mmol/mL Ang Ⅱ stimulation significantly increased the protein expression levels of Bip， p-IRE1， and Bid in H9c2 cells （P<0.05， P<0.01）， indicating the induction of endoplasmic reticulum stress， activation of the IRE1/RIDD signaling pathway， and initiation of the apoptosis process. Compared with the blank group， the model group showed a significant increase in the surface area of H9c2 cells and the apoptosis rate of cardiomyocytes， as well as in both early and late apoptosis rates （P<0.01）. The expression levels of Bid， Bax， cleaved-Caspase-3， and cleaved-Caspase-8 proteins were significantly increased， while the expression level of Bcl-2 protein was significantly decreased （P<0.01）. The expression levels of Bip， p-IRE1， and p-RIDD proteins were significantly increased （P<0.05， P<0.01）. Compared with those in the model group， the surface area of cardiomyocytes and the apoptosis rate of cardiomyocytes in all ETH groups were significantly decreased after drug intervention. Both early and late apoptosis rates were significantly decreased. The expression level of cleaved-Caspase-8 was significantly decreased in the low-dose ETH group （P<0.05）. The expression levels of Bid， Bax， and cleaved-Caspase-8 were significantly decreased in the medium-dose ETH group （P<0.05， P<0.01）. The high-dose ETH group significantly reduced the expression levels of Bid， Bax， cleaved-Caspase-3， and cleaved-Caspase-8 （P<0.05， P<0.01） and significantly increased the expression level of Bcl-2 （P<0.05）. The level of p-IRE1 protein in the medium-dose ETH group was significantly decreased （P<0.01）. The expression levels of Bip， p-IRE1， and p-RIDD proteins in the high-dose ETH group were significantly decreased （P<0.05， P<0.01）. ConclusionETH can alleviate Ang Ⅱ-mediated cardiomyocyte apoptosis by inhibiting the IRE1/RIDD signaling pathway and further alleviate the cardiac injury caused by hypertension.

Objective:To understand the current status of oral frailty in elderly diabetic patients and analyze its influencing factors.Methods:A convenience sampling method was used to select elderly diabetic patients hospitalized at Henan Cancer Hospital and Henan Provincial People's Hospital from October 2023 to May 2024. The general information questionnaire, Oral Frailty Index-8 (OFI-8) , Short Form of Health Literacy Dental Scale (HeLD-14) , Nutritional Risk Screening 2002 (NRS 2002) , and the Diabetes Distress Scale (DDS) were used to collect data. Binary Logistic regression analysis was used to examine the influencing factors of oral frailty in elderly diabetic patients.Results:A total of 235 questionnaires were distributed, and 220 valid questionnaires were returned, with an effective response rate of 93.62% (220/235) . The incidence of oral frailty in elderly diabetic patients was 46.82% (103/220) . The binary Logistic regression analysis showed that glycated hemoglobin, dry mouth, remaining teeth, nutritional risk, oral health literacy, and diabetes distress were significant influencing factors for the occurrence of oral frailty in elderly diabetic patients ( P<0.05) . Conclusions:The current status of oral frailty in elderly diabetic patients is concerning. Healthcare providers should pay attention to the oral health status of elderly diabetic patients and provide targeted nursing interventions and recommendations based on the influencing factors of oral frailty, in order to reduce its occurrence.

Spinal cord injury(SCI)is a structural and functional disruption of the spinal cord caused by various factors,leading to neurological dysfunction.As a common central nervous system disorder in clinical practice,SCI poses significant risks to human life and health.Its pathological mechanism is exceedingly complex,involving multiple pathological processes.Given the irreversibility of primary injury,targeting secondary injury has gradually become the main direction for the clinical treatment of SCI in recent years.Recent studies have highlighted the crucial role of blood-spinal cord barrier damage and microvascular dysfunction in the progression of secondary injury following SCI.Therefore,investigating the pathological mechanisms of microcirculation and exploring targeted therapies could provide valuable insights for clinical SCI treatment.This paper aims to provide an objective review of the role of microcirculation in SCI,identify the critical regulators of microvascular function,and summarize strategies for treating SCI by targeting microcirculation.The findings of this study may offer novel references for the clinical management of SCI.

Spinal cord injury(SCI)is a central nervous system disease with high morbidity and disability rates,bringing serious economic and psychological burdens to families and society worldwide.AMP-activated protein kinase(AMPK)is an important sensor in the energy metabolism process in living organisms,which plays a central role in maintaining energy balance.It is currently considered a key target for the prevention and treatment of multiple diseases.Studies have shown that AMPK signaling can regulate autophagy,neuroinflammation,oxidative stress,mitochondrial function and other processes after SCI,thus affecting the pathological process of SCI.This review summarizes the research progress on AMPK signaling pathway involved in the regulation of SCI,in order to provide new ideas for the treatment and drug development of SCI.
