Recently, photodynamic therapy (PDT) has gained considerable attention as a promising therapeutic approach for the treatment of psoriasis. Unfortunately, the activation of high mobility group box 1 protein (HMGB1) by PDT triggers innate and adaptive immune responses, which exacerbate skin inflammation. Herein, we combined glycyrrhizic acid (GA), a natural anti-inflammatory compound and immunomodulator derived from the herb Glycyrrhiza uralensis Fisch., with PDT actuated by the photosensitizer chlorin e6 (Ce6) by co-loading them in GA-based lipid nanoparticles coated with a catechol-modified quaternary chitosan salt (GC NPs/QCS-C). GC NPs/QCS-C exhibited high drug loading efficacy, uniform size distribution, an ideal topical adhesive property, enhanced skin retention and penetration in psoriasis-like lesions, and high intracellular uptake in epidermal cells compared with the counterparts. Subsequently, the transdermal administration of GC NPs/QCS-C followed by near-infrared laser radiation in an imiquimod-induced psoriasis-like mouse model significantly ameliorated psoriasis symptoms, promoted the apoptosis of hyperproliferative epidermal cells, and alleviated the inflammatory cascade. The significant therapeutic outcomes of GC NPs/QCS-C were attributed to the synergistic effects of GA and PDT on modulating immune cell recruitment and inhibiting dendritic cell maturation. Our results demonstrated that the topical bio-adhesive nanosystem that combines GA and Ce6 offers a synergistic chemo-phototherapeutic strategy for psoriasis treatment.

Objective To explore the influencing factors of depression risk in elderly patients with hypertension and construct and validate a nomogram prediction model.Methods A total of 869 elderly patients with hypertension were selected from national survey database of the China Health and Retirement Longitudinal Study(CHARLS)in 2018.Multivariate Logistic regression analysis was used to identify the risk factors for depression in elderly patients with hypertension,and a nomogram prediction model was constructed.The accuracy and effectiveness of the model were validated by the Hosmer-Lemeshow(H-L)goodness-of-fit test,the area under the curve(AUC)of the receiver oper-ating characteristic(ROC)curve,and the calibration curve.Results The incidence of depression in elderly patients with hypertension was 47.18％.Factors influencing the risk of depression included rural residence(OR=2.191,P＜0.05),impaired basic activities of daily living(BADL)(OR=2.338,P＜0.05),impaired instrumental activitiesofdaily living(IADL)(OR=1.674,P＜0.05),poor life satisfaction(OR=7.348,P＜0.05),fair self-rated health(OR=0.441,P＜0.05),good self-rated health(OR=0.259,P＜0.05),and sleep duration of 6 to 9 hours(OR=0.510,P＜0.05).The AUC of the ROC curve was 0.795,the slope of the calibration curve was close to 1,and the H-L goodness-of-fit test yielded x2=5.074.The validation set showed an AUC of 0.703.Conclusion The prediction model established in this study has high accuracy and discriminative ability.Healthcare professionals can take effective preventive measures based on individual patient factors.

BACKGROUND: As an essential part of health services, rehabilitation is of great significance to improve the health and quality of life of the whole population. Accelerating aging calls for a significant expansion of rehabilitation services in China, but rehabilitation needs remain unclear. We conducted the study to explore the rehabilitation needs in China and project the trend of rehabilitation needs from 2020 to 2034. METHODS: The data of health conditions that might potentially benefit from rehabilitation were obtained from Global Burden of Disease (GBD) study. Estimated annual percentage changes (EAPCs) were calculated to quantify the trends of the age-standardized rates. Projections of rehabilitation needs were made until 2034 using Bayesian age-period-cohort analysis (BAPC). RESULTS: Approximately 460 million persons (33.3% of the total population) need rehabilitation in China, contributing to 63 million years lived with disabilities (YLDs) in 2019. The number of prevalent cases that need rehabilitation increased from around 268 (95% uncertainty interval [UI]: 257-282) million in 1990 to almost 460 (95% UI: 443-479) million in 2019, representing an increase of 71.3%. The highest contribution to the need for rehabilitation was musculoskeletal disorders with about 322 (95% UI: 302-343) million persons in seven aggregate disease and injury categories, and hearing loss with over 95 (95% UI: 84-107) million people among 25 health conditions. Based on the projection results, there will be almost 636 million people (45% of the total population) needing rehabilitation services in China by 2034, representing an increase of 38.3%. The rehabilitation needs of neoplasms, cardiovascular diseases, and neurological disorders are expected to increase significantly from 2019 to 2034, with increases of 102.3%, 88.8% and 73.2%, respectively. CONCLUSIONS The need for rehabilitation in China substantially increased over the last 30 years. It is predicted that over two in five people will require rehabilitation by 2034, thus suggesting the need to develop rehabilitation services that meet individuals' rehabilitation needs.

Objective:To analyze the genetic variant characteristics of primary immunodeficiency diseases (PID) in families from Henan Province.Methods:This study conducted a retrospective analysis of 19 PID pedigrees referred to the Prenatal Diagnosis Center at Henan Provincial People's Hospital between January 2016 and March 2024. Among the 19 families, 13 underwent prenatal diagnosis at our hospital, while the remaining six received genetic counseling based on third-party genetic testing reports (confirmed by our institution's laboratory). The clinical data from these families were analyzed, and descriptive statistical analysis was applied to the data.Results:Among the 19 PID families, there were seven cases of combined immunodeficiency, three immunodeficiency syndromes, three phagocyte deficiencies, three antibody-dominant immunodeficiencies, and three immunodysregulatory disorders, involving a total of 12 genes ( IL2RG, ADA, RAG2, STAT3, SMARCAL1, ATM, POLA1, CYBB, BTK, RAB27A, LRBA, IL10R). A total of 25 genetic variants were identified, including 11 novel variants not previously documented in the ClinVar and HGMD professional databases. The novel variants comprised: IL2RG gene mutations (Exon5_8del and c.903_904delinsCT leading to p.E302*), ADA gene mutation (c.884A>G resulting in p.D295G), RAG2 gene mutation (c.513dupA causing p.W172Mfs3), POLA1 gene mutation (c.25+5G>C), CYBB gene mutations (c.824G>A/p.G275D and c.472A>T/p.K158), BTK gene mutations (c.522_523insC/p.A175fs and c.142-2A>C), and RAB27A gene mutations (c.121delA/p.T41fs and c.272delA/p.D91fs). Among the 13 families undergoing prenatal diagnosis, genetic testing revealed that 11 fetuses carried wild-type genes, and these families elected to continue their pregnancies. One fetus exhibited identical genetic variants to the proband and received a clinical diagnosis consistent with the genetic disorder, while another fetus demonstrated chromosomal copy number variations. In both of these latter cases, the families opted for pregnancy termination. Conclusion:This study identified 11 unreported variants across seven genes, highlighting the need for further expansion of PID genetic variant databases.

Objective To discuss the prediction value of the early efficacy of hepatic arterial infusion chemotherapy(HAIC)in treating stage Ⅱ-Ⅲ hepatocellular carcinoma(HCC).Methods The clinical data of 81 patients with stage Ⅱ-Ⅲ HCC,who received at least 3 times of HAIC at the Nanchang Municipal Central Hospital of China from November 2021 to March 2024,were retrospectively analyzed.CT or MRI was used to compare patient's local tumor response after each treatment cycle.Based on modified Response Evaluation Criteria in Solid Tumors(mRECIST),the curative effects of patients after receiving the first,the second,and the last HAIC treatment were compared between each other.The prediction value of the early efficacy of HAIC in treating patients with stage Ⅱ-Ⅲ HCC was analyzed.Results In the 67 patients,the efficacy of the last time HAIC was equal or similar to that of the first time HAIC,and in the remaining 14 patients the efficacy of the last time HAIC was different from that of the first time HAIC,with an efficacy prediction rate of 82.72％.The efficacy of the last time HAIC was equal or similar to that of the second time HAIC in 71 patients,and in the remaining 10 patients the efficacy of the last time HAIC was different from that of the second time HAIC,with an efficacy prediction rate of 87.65％.Conclusion In treating stage Ⅱ-Ⅲ HCC with HAIC,the early efficacy can be used to predict the final efficacy after completion of the total treatment course.

Objective:To prepare domestic 64Cu-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid- D-Phe1-Tyr3-Thr8-octreotide (DOTATATE), and to verify its distribution and preliminary diagnostic value in neuroendocrine tumors (NETs). Methods:DOTATATE was labeled with the domestic 64Cu to obtain 64Cu-DOTATATE. The lipophilicity, in vitro stability, and pharmacokinetics were studied. Biodistribution experiments and microPET imaging were performed on NCI-H727 (somatostatin receptor (SSTR)2 positive expression) tumor-bearing nude mice. The preliminary clinical applications were conducted on 10 NETs patients (5 males, 5 females; age (58.5±13.0) years) from Chinese PLA General Hospital between May 2023 and April 2024. Data were analyzed by using independent-sample t test. Results:64Cu-DOTATATE was successfully prepared with the radiochemical purity greater than 98%, log P of -2.609±0.051 and good stability. Pharmacokinetic experiments in BALB/c mice suggested rapid blood clearance of the drug (elimination half-time of 22.78min). Biodistribution results in tumor-bearing mice showed that 64Cu-DOTATATE was mainly metabolized through the liver and kidneys, with significant tumor uptake at 1h ((2.519±0.273) percentage activity of injection dose per gram of tissue (%ID/g)) and sustained high uptake at 24h ((4.331±0.549)%ID/g). MicroPET imaging of tumor-bearing mice showed a slight increase in uptake and good retention at 24h, with a significant statistical difference compared to the blocked group ((2.197±0.250) vs (0.985±0.064) % ID/g; t=6.40, P=0.008). The tumor/liver ratios were 0.075±0.007, 0.083±0.011, 0.118±0.005, 0.263±0.031 at 1, 2, 6 and 24h, respectively. Preliminary clinical application indicated that 64Cu-DOTATATE exhibited good targeting in patients, and the liver radioactivity distribution was moderate (SUV max=10.62±3.46), providing good image quality. Conclusion:Domestic 64Cu-DOTATATE PET/CT imaging is a promising imaging evaluation method in NETs with the value for further clinical research.

Objective:The objective of this longitudinal study is to longitudinally monitor the lexical development and language proficiency of Mandarin-speaking children with cochlear implants (CI) over a three-year post-implantation period while also investigating whether early receptive and expressive vocabulary skills can serve as predictors for later language abilities in CI recipients.Methods:In this study, 42 children with CIs were selected as participants, including 19 males and 23 females, and with a mean age at CI activation of 16.6±4.9 months. Receptive and expressive vocabulary skills were assessed using the Infant Checklist of the Early Vocabulary Inventory for Mandarin Chinese (EVI) at one-year post-activation (T1). Additionally, expressive vocabulary sizes were evaluated using the EVI-Toddler Checklist, while syntactic ability was measured by the Grammatical Complexity test of the Mandarin-Chinese Communicative Developmental Inventory for Infants and Toddlers at two years post-activation (T2). The comprehensive language development level of preschool children, including language comprehension, expression, and grammar ability, was examined during the third year post-activation (T3) using the Revised Scale for Assessment of Language Disorders in Preschool Children. Data analysis was conducted using SPSS 22.0.Results:One year after CI activation, children exhibited a mean receptive vocabulary size of 155.7±52.8 and an expressive vocabulary size of 85.1±63.9. T2′s expressive vocabulary size was 455.7±167.7, while the Grammatical Complexity score was 36.5±13.0. The original language development score was determined to be 53.6±14.2 at T3. Correlation analysis revealed significant positive associations between T1′s receptive and expressive vocabulary with tests conducted at T2 and subsequent language development measured at T3 ( P<0.01). Furthermore, there was a significant correlation between expressive vocabulary at T1 and both tests conducted at T2 ( P<0.01), but no significant correlation with subsequent language development measured at T3. Regression analysis showed that T1 receptive vocabulary significantly predicted T2 expressive vocabulary and Grammatical Complexity scores and T3 language development scores. Moreover, the syntactic ability assessed during T2 independently predicted subsequent language proficiency measured at T3. Conclusions:Early receptive vocabulary and grammar ability two years post CI activation significantly predict later language proficiency in children with cochlear implants. Thus, during rehabilitation, emphasis should be placed on enhancing vocabulary and grammar comprehension.

Objective:To study the distribution characteristics of current patients with Kashin-Beck disease (KBD) in Molidawa Daur Autonomous Banner (referred to as Morin Banner), and provide suggestions for service management.Methods:Information of KBD current patients in Morin Banner was collected from January 1, 2018 to June 30, 2024 using the "KBD Current Patient Survey System" provided by the Center for Endemic Disease Control, Chinese Center for Disease Control and Prevention. A descriptive study method was used to analyze the basic information and clinical data of current patients.Results:As of June 30, 2024, a total of 6 223 KBD current patients were reported in Morin Banner, and the patients were distributed in 15 townships (towns). There was a statistically significant difference in the prevalence rate of KBD among different townships (towns, χ 2 = 3 069.01, P < 0.001). The minimum age of the KBD current patients was 27 years old, and the maximum was 98 years old, mainly concentrated in the age range of 45 - 74 years old, accounting for 95.7% (5 954/6 223). There was a significant difference in the prevalence rate of KBD among different age groups (χ 2 = 5 912.76, P < 0.001). The male to female ratio was 1.00∶1.14 (2 910 ∶ 3 313), and there was a statistically significant difference in prevalence rate of KBD between genders(χ 2 = 44.38, P < 0.001). The KBD current patients mainly had a primary school education, married, and farmers, accounting for 59.2% (3 685/6 223), 89.8% (5 590/6 223), 93.2% (5 802/6 223), respectively; and the clinical grading of patients is mainly degree Ⅰ. There was a statistically significant difference in the rate of limb disability among patients with different clinical grades (χ 2 = 64.26, P < 0.001). The rate of limb disability in males was higher than that in females (χ 2 = 10.36, P = 0.001). Conclusions:The KBD current patients in Morin Banner are distributed in various township (town), with middle-aged and elderly famers being the main ones. It is necessary to strengthen monitoring of KBD, and pay attention to personalized treatment and management of KBD current patients.

Objective:To analyze the quality level of maternal mid-trimester serum prenatal screening in China from 2019 to 2023.Methods:A questionnaire survey was conducted to collect information from laboratories participating in the National Health Commission′s Clinical Laboratory Center inter-laboratory quality assessment program for prenatal screening from 2019 to 2023. The collected data included screening protocols, detection methods, testing systems, and monthly laboratory screening quality indicators. The Chi-square test was used to compare the initial screening positive rates among different screening protocols, provinces, detection methods, and testing systems. A log-transformed linear regression analysis was performed to evaluate the relationship between the average annual sample size and the out-of-control rate of various median multiple of the median (mMoM) values.Results:This study included 806 laboratories from 29 provinces (including autonomous regions and municipalities). The five-year average out-of-control rates for mMoM values across indicators ranged from 15.8% to 31.3%. The initial positive rates of dual, triple, and quadruple screening protocols were statistically different ( χ2=760.2, P<0.001). The initial positive rates across different provinces ranged from 4.7% to 10.3%, with statistically significant differences ( χ2=35 388.0, P<0.001). There were also statistically significant differences in initial positive rates between different testing systems ( χ2=2 493.2, P<0.001). Testing systems using chemiluminescence methods had significantly higher initial positive rates compared to systems using time-resolved fluorescence methods (7.2% vs. 6.5%, χ2=533.6, P<0.001). Log-linear regression analysis showed that testing systems with larger annual average sample sizes had lower out-of-control rates for mMoM values (AFP: β=-0.100, P=0.005; hCG: β=-0.123, P=0.008; uE3: β=-0.139, P=0.007). Conclusion:There are significant differences in the quality of maternal mid-trimester serum screening across different detection methods, testing systems and provinces in China.

Objective:To investigate the current status of preimplantation genetic testing for aneuploidies (PGT-A) in China in 2024 and to provide recommendations for ensuring the consistency of PGT-A results.Methods:This study was a nationwide external quality assessment research. The National Center for Clinical Laboratories of the National Health Commission conducted two surveys in June and December 2024, with participation from 31 laboratories across China. During each survey, quality control samples of varying concentrations were distributed: the first survey distributed 6 samples (Batch Nos. 202401-202406) and the second survey distributed 3 samples (Batch Nos. 202431-202433). Participating laboratories were required to submit information including detection platforms, single-cell amplification methods, library construction methods, sequencing instruments, and test results. Collected data were statistically analyzed using Microsoft Excel to evaluate laboratories' PGT-A testing capabilities and determine whether results met predefined quality control requirements.Results:All 31 laboratories submitted results for both surveys. In the first survey, 90.3% (28/31) met qualification criteria with a 9.7% failure rate (3/31). For individual batches, pass rates were 90.3% (28/31) for batches 202401-202403 and 100% (31/31) for batches 202404-202406. The second survey achieved 100% (31/31) compliance across all three batches (202431-202433), with each batch maintaining a 100% pass rate.Conclusion:The detection quality of PGT-A in China is generally good, but with differences, and factors such as sample concentration, transportation conditions and detection methods affect the consistency of the results. The study highlights the urgent need for nationwide external quality assessment of PGT-A in China. This will help identify issues in laboratories in a timely manner and ensure the consistency of PGT-A test results.
