OBJECTIVE To evaluate the long-term cost-effectiveness of canagliflozin or semaglutide in patients with type 2 diabetes mellitus（T2DM）poorly controlled with metformin. METHODS Based on the perspective of China’s health system， a Markov model was used to calculate the long-term costs and utilities of canagliflozin or semaglutide combined with metformin for T2DM patients in China for 30 years based on the data from SUSTAIN 8 study. The incremental cost-effectiveness ratio（ICER） and incremental net monetary benefit （INMB） were calculated using one time the 2024 per capita gross domestic product（GDP） as the willingness-to-pay（WTP） threshold. One-way sensitivity analysis， probability sensitivity analysis and scenario analysis were conducted to confirm the stability of the conclusions. RESULTS Compared with canagliflozin + metformin， ICER of semaglutide combined with metformin was 260 485.67 yuan/quality-adjusted life year （QALY），which was higher than the WTP threshold set in this study （95 749 yuan/QALY），and the corresponding INMB was －61 576.24 yuan，indicating that the canagliflozin + metformin regimen was more cost-effective. The cost of diabetes without complications treatment in the semaglutide + metformin group had the greatest influence on INMB，but changes in parameters within the selected range did not drive decision reversal. With the increasing of WTP threshold，the economic acceptability of semaglutide + metformin regimen increased. Under the current WTP threshold，the annual cost of semaglutide should be reduced by 42.95% to make the semaglutide + metformin regimen more cost- effective. CONCLUSIONS From the perspective of China’s health system， canagliflozin + metformin is more cost-effective than semaglutide + metformin for T2DM patients yueru. with poor glycemic control with metformin alone.

Objective To understand the application effect of early screening scale and behavioral intervention effect in children with autism spectrum disorder (ASD). Methods A total of 348 children with suspected ASD were selected and evaluated using the Modified Checklist for Autism in Toddlers (M-CHAT) and Autism Behavior Checklist (ABC). The evaluation results were compared with those from the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Children enrolled were given Early start Denver model (ESDM) intervention. The evaluation results of Gesell Developmental Scale and Autism Treatment Evaluation Checklist (ATEC) scores were compared before and after intervention. Results The sensitivity, specificity, accuracy and Kappa value of M-CHAT for evaluating ASD in children aged 1-3 years were 89.53%, 90.70%, 89.92% and 0.78. The corresponding values of ABC were 78.49%, 81.40%, 79.46% and 0.56. The sensitivity, specificity, accuracy and Kappa value of M-CHAT for evaluating children aged >3-6 years were 87.30%, 77.78%, 84.44% and 0.64. The corresponding values of ABC were 85.71%, 77.78%, 83.33% and 0.62. The sensitivity and accuracy of M-CHAT were higher than ABC for evaluating ASD in children aged 1-3 years (P<0.05). There were no significant differences in sensitivity, specificity and accuracy between M-CHAT and ABC for evaluating ASD in children aged 3-6 years (P>0.05). After intervention, development quotients (DQ) of personal-social aspects, adaptability, language, gross motor, and fine motor of children with ASD were higher than those before intervention (P<0.05). ATEC scores for language, behavior, sensation, and social contact of children with ASD were lower than those before intervention (P<0.05). Conclusion M-CHAT and ABC both can be used for early screening of ASD in children, especially M-CHAT. Early behavioral intervention can effectively improve the condition and developmental level of children with ASD.

Salivary gland mucosa-associated lymphoid tissue lymphoma (SGML) is a subvariety of marginal zone B-cells that occurs outside of mucosal lymph nodes. The onset of SGML is closely related to immunity, chronic infections, and genetic factors, such as lymphoepithelial sialadenitis (LESA) and Sjogren’s syndrome (SS), as well as Helicobacter pylori, hepatitis C virus, Epstein-Barr virus, and human T-lymphocytic virus. The most common site of SGML is the parotid gland, followed by the submandibular gland, small salivary gland, and sublingual gland. SGML is more common in middle-aged and elderly women, and patients often have autoimmune diseases, such as Sjogren’s syndrome or rheumatoid arthritis. SGML can be diagnosed through clinical manifestations, imaging, and histopathology, but histopathological biopsy remains the main method for confirming SGML. Traditional treatment methods include anti-infective therapy and surgery combined with radiation or chemotherapy. In recent years, some new treatment methods, such as Bruton tyrosine kinase (BTK) inhibitors and programmed cell death protein-1 (PD-1) inhibitors, have been effective against recurrent or refractory SGML, but more clinical trial data are needed to support them. At present, the optimal treatment for SGML is not yet clear. Individualized treatment plans should be developed based on the location, staging, clinical characteristics, and overall health status of the patient. SGML progresses slowly and has a relatively good overall prognosis; however, the disease is recurrent, the treatment cycle is long, the recurrence rate is higher than that of other mucosa-associated lymphoid tissue lymphomas, and SGML may also cause other serious complications. Therefore, regular observation and follow-up are very important for its prognosis. This article reviews the etiology, diagnosis, treatment, and prognosis of SGML, with the aim of providing a reference for clinical diagnosis and treatment, and thus improve the survival rate of patients with SGML.

OBJECTIVE To evaluate the safety， efficacy， and cost-effectiveness of sodium-glucose co-transporter 2 （SGLT-2） inhibitors for treating type 2 diabetes mellitus （T2DM）. METHODS Retrieved databases such as PubMed， Cochrane Library， Embase， CNKI， as well as relevant health technology assessment （HTA） official websites， HTA reports， systematic review/meta- analysis and pharmacoeconomic studies about SGLT-2 inhibitors （including 12 types such as canagliflozin， dapagliflozin， and empagliflozin） in the treatment of T2DM were collected from the inception to January 28， 2025. After literature screening data extraction and quality assessment， a descriptive analysis was conducted on the results of the included studies. RESULTS A total of 38 articles were included， comprising 30 systematic reviews/meta-analyses， 4 pharmacoeconomic studies， and 4 HTA reports. In terms of effectiveness， most research results showed that canagliflozin was effective in controlling blood glucose， reducing body weight， and lowering blood pressure compared to other SGLT-2 inhibitors， while empagliflozin could effectively reduce all-cause mortality. In terms of safety， compared with other SGLT-2 inhibitors， empagliflozin has a lower overall adverse event rate and cardiovascular death risk， canagliflozin presented a higher risk of hypoglycemia， and dapagliflozin had a higher risk of urinary tract infections. In terms of economics， empagliflozin possessed greater economic advantages over both dapagliflozin and canagliflozin， while canagliflozin offered more benefits than dapagliflozin. CONCLUSIONS The selection of SGLT-2 inhibitors for the treatment of T2DM should be individualized. Canagliflozin is recommended for patients with high cardiovascular risk. Empagliflozin boasts the best overall safety profile. Dapagliflozin should be used with caution in patients at high risk of urinary tract infections. Based on foreign economic evidence， empagliflozin has economic advantages. In the future， drug economic studies under the Chinese health system need to be conducted.

The quality of traditional Chinese medicine (TCM) prescriptions (TCMPs) is critical to clinical efficacy; however, evaluating their consistency and identifying sources of variability remain challenging. This study proposes an integrated strategy to assess the quality of 100 widely sold TCMPs. A "one-for-all" chromatographic method was employed to analyze 645 sample batches. This large-scale data collection enabled statistical evaluations, such as hierarchical cluster analysis (HCA) and similarity heatmap, to identify quality inconsistencies. The introduction of a TCM-specific mass spectrometry (MS) database allowed for rapid, automated annotation of chemicals across 100 prescriptions and facilitated the tracing of raw material sources. Results indicate that 19% of prescriptions exhibited chemical inconsistencies, which are associated with high market value, low pricing, and substantial price disparities. The MS database allowed rapid annotation of 761 and 673 compounds in positive and negative modes, respectively, in 100 TCMPs, with 73 prescriptions reported for the first time. The tracing efforts succeeded in identifying >40% of the raw material sources for 51 prescriptions. P93 (Yinianjin (YNJ)) is a case in which the chromatographic profiles from three manufacturers displayed inconsistencies. Analysis using the database traced divergent peaks to Rhei Radix et R hizoma (RRER). Verification with self-prepared samples confirmed that manufacturers utilized three distinct botanical sources. This integrated strategy provides a scalable framework for quality control in TCMPs.

Objective:To analyze the survival of pneumoconiosis patients in Guangzhou from 1958 to 2018, explore the factors affecting the survival of pneumoconiosis, and provide scientific basis for formulating the guidelines and policies for treatment and assistance of pneumoconiosis.Methods:From July 2019 to January 2020, 1194 cases of occupational pneumoconiosis patients diagnosed by institutions qualified for pneumoconiosis diagnosis in Guangzhou from June 1, 1958 to December 31, 2018 were studied. Excluding 258 patients who lacked survival data, 936 patients were included in the pneumoconiosis survival analysis. Life table method was used to estimate the survival rate, Kaplan-Meier method was used to draw the survival curve, log-rank test was used to compare the groups, and Cox proportional risk regression model was used to analyze the influencing factors of survival.Results:The 10, 20 and 30 years cumulative survival rates of pneumoconiosis patients in Guangzhou were 62.8%, 35.2% and 15.4%, respectively. The median survival time was 19.4 years. log-rank test showed that there were statistically significant differences in the survival curves of pneumoconiosis patients between group without tuberculosis and group with tuberculosis ( P<0.001), and there were statistically significant differences among different stages and categories of pneumoconiosis ( P<0.001). Age of exposure to dust ( HR=1.03, 95% CI: 1.01-1.05), age of diagnosis ( HR=1.02, 95% CI: 1.00-1.04), combined pulmonary tuberculosis ( HR=1.46, 95% CI: 1.18-1.81), stage of pneumoconiosis (stage Ⅲ vs. stage Ⅰ, HR=2.26, 95% CI: 1.47-3.48) and categories of pneumoconiosis (fibrogenic mineral dust pneumoconiosis and metallogenic pneumoconiosis, HR=2.45, 95% CI: 1.61-3.74; non-fibrogenic mineral pneumoconiosis and metallogenic pneumoconiosis, HR=2.67, 95% CI: 1.47-4.87; mixed pneumoconiosis and metallogenic pneumoconiosis, HR=2.25, 95% CI: 1.11-4.56) were the factors affecting the survival time of pneumoconiosis patients ( P<0.05) . Conclusion:Pulmonary tuberculosis may increase the risk of death in patients with pneumoconiosis. Mineral dust pneumoconiosis, mixed pneumoconiosis and stage Ⅲ pneumoconiosis may also have higher risk of death.

Objective:To study the role and specific mechanisms of glucose-6-phosphate dehydrogenase (G6PD), a key enzyme for glycometabolism, mediated reduction stress in arsenic-induced malignant transformation of cells.Methods:Immortalized human skin keratinocyte-forming cells (HaCaT cells) were treated with sodium arsenite (NaAsO 2) at a concentration of 0.0 (control group) and 1.0 μmol/L (arsenic group), and malignant transformation indicators were tested using cell growth kinetics assay, cell scratch assay, and soft agar colony formation assay. At different stages of arsenic treatment (0, 1, 7, 14, 21, 28, 35 passages of cells), the effects of NaAsO 2 on glycometabolism in HaCaT cells were determined using corresponding reagent kits and Western blot, including glucose-6-phosphate (G6P), lactate, acetyl CoA, G6PD levels, as well as protein expression levels of hexokinase 2 (HK-2), 6-phosphofructose-2-kinase/fructose-2, 6-diphosphatase 3 (PFKFB3), pyruvate dehydrogenase kinase 1 (PDK1), 6-phosphoglucose dehydrogenase (PGD), and G6PD. Mitochondria were extracted, and the effects of NaAsO 2 on HaCaT cells and mitochondrial redox [reduced nicotinamide adenine dinucleotide phosphate (NADPH)/nicotinamide adenine dinucleotide phosphate (NADP +) ratio, reduced glutathione (GSH)/oxidized glutathione (GSSG) ratio] were determined using corresponding reagent kits. The effect of G6PD on reduction stress and NaAsO 2-induced malignant transformation of HaCaT cells was determined using small interfering RNA (siRNA) intervention method. Results:Compared 1.0 μmol/L NaAsO 2-cultured HaCaT cells up to 35 generations (T-HaCaT cells) with matching passage 0.0 μmol/L NaAsO 2-cultured HaCaT cells [(33.797 ± 0.280) h, 0.177 ± 0.015, 13.667 ± 2.625], the multiplication time [(24.042 ± 0.479) h] was shorter ( t = 30.45, P < 0.001), the cell migration rate (0.396 ± 0.039) was higher ( t = 9.08, P < 0.001), and the number of colonies formed in soft agar (73.667 ± 4.450) was higher ( t = 20.11, P < 0.001). Compared with matching passage control group cells and 0 generation of the same group, G6P level in the arsenic group was higher at passages 1, 7, 14, 21, 28 and 35 ( P < 0.05), lactate and G6PD levels were higher at passages 14, 21, 28 and 35 ( P < 0.05), acetyl CoA level was lower at passages 21, 28 and 35 ( P < 0.05), and protein expression levels of HK-2, PFKFB3, PDK1, PGD, and G6PD were higher at passages 7, 14, 21, 28 and 35 ( P < 0.05). The NADPH/NADP + ratio of cells was higher at passages 1, 14, 21, 28 and 35 ( P < 0.05), GSH/GSSG ratio was higher at passages 21, 28 and 35 ( P < 0.05). The ratio of mitochondrial NADPH/NADP + was higher at passages 1, 7, 21, 28 and 35 ( P < 0.05), the GSH/GSSG ratio was higher at passages 1, 7, 14, 21, 28 and 35 ( P < 0.05). G6PD expression was silenced by siRNA in T-HaCaT cells, compared with the T-HaCaT con siRNA-treated group, the T-HaCaT G6PD siRNA-treated group had lower NADPH/NADP + and GSH/GSSG ratios in both cells and mitochondria ( P < 0.05), longer cell multiplication time, lower cell migration rate, and fewer soft agar colonies ( P < 0.05). Conclusion:During the malignant transformation of HaCaT cells induced by NaAsO 2, G6PD and other enzymes related to glycometabolism are activated, leading to reprogramming of glycometabolism, resulting in an imbalance of cell redox homeostasis and enhanced reduction stress in cells and mitochondria, thereby promoting NaAsO 2 induced malignant transformation of HaCaT cells.

Objective:To explore the diagnosis and treatment of adolescence-onset methylenetetrahydrofolate reductase (MTHFR) deficiency.Methods:This was a retrospective case study. Nine patients with adolescence-onset MTHFR deficiency were diagnosed at Peking University First Hospital from January 2016 to December 2022, and followed up for more than 1 year. Their general information, clinical manifestations, laboratory tests, cranial images, MTHFR gene variants, diagnosis, treatment, and outcome were analyzed retrospectively.Results:The 9 patients came from 8 families. They had symptoms at age of 8.0 years to 17.0 years and diagnosed at 9.0 years to 17.5 years. Eight were male and 1 was female. Two patients were brothers, the elder brother developed abnormal gait at 17.0 years; and the younger brother was then diagnosed at 15.0 years of age and treated at the asymptomatic stage, who was 18.0 years old with normal condition during this study. The main manifestations of the 8 symptomatic patients included progressive dyskinesia and spastic paralysis of the lower limbs, with or without intellectual decline, cognitive impairment and behavioral abnormalities. Totally, 15 variants of MTHFR gene were identified in the 9 patients, including 8 novel variants. Five patients had brain image abnormalities. Increased plasma total homocysteine level (65-221 μmol/L) was found in all patients, and decreased to 20-70 μmol/L after treatment with betaine and calcium folinate. Besides, the 8 symptomatic patients had their behavior and cognitive problems significantly improved, with a legacy of lower limb motor disorders.Conclusions:Late-onset MTHFR deficiency can occur in adolescence. The diagnosis is usually delayed because of non-specific clinical symptoms. The test of blood total homocysteine could be used as a selective screening test. Eight novel varients of MTHFR gene were identified. Timely treatment can improve clinical condition significantly, and pre-symptomatic treatment may prevent brain damage.

Objective:To investigate the clinical features and outcomes of adolescence-onset methylmalonic acidemia (MMA) and explore preventive strategies.Methods:This was a retrospective case analysis of the phenotypes, genotypes and prognoses of adolescence-onset MMA patients. There were 55 patients diagnosed in Peking University First Hospital from January 2002 to June 2023, the data of symptoms, signs, laboratory results, gene variations, and outcomes was collected. The follow-ups were done through WeChat, telephone, or clinic visits every 3 to 6 months.Results:Among the 55 patients, 31 were males and 24 were females. The age of onset was 12 years old (range 10-18 years old). They visited clinics at Tanner stages 2 to 5 with typical secondary sexual characteristics. Nine cases (16%) were trigged by infection and 5 cases (9%) were triggered by insidious exercises. The period from onset to diagnosis was between 2 months and 6 years. Forty-five cases (82%) had neuropsychiatric symptoms as the main symptoms, followed by cardiovascular symptoms in 12 cases (22%), kidney damage in 7 cases (13%), and eye disease in 12 cases (22%). Fifty-four cases (98%) had the biochemical characteristics of methylmalonic acidemia combined with homocysteinemia, and 1 case (2%) had the isolated methylmalonic acidemia. Genetic diagnosis was obtained in 54 cases, with 20 variants identified in MMACHC gene and 2 in MMUT gene. In 53 children with MMACHC gene mutation,1 case had dual gene variants of PRDX1 and MMACHC, with 105 alleles. The top 5 frequent variants in MMACHC were c.482G>A in 39 alleles (37%), c.609G>A in 17 alleles (16%), c.658_660delAAG in 11 alleles (10%), c.80A>G in 10 alleles (10%), c.567dupT and c.394C>T both are 4 alleles (4%). All patients recovered using cobalamin, L-carnitine, betaine, and symptomatic therapy, and 54 patients (98%) returned to school or work.Conclusions:Patients with adolescence-onset MMA may triggered by fatigue or infection. The diagnosis is often delayed due to non-specific symptoms. Metabolic and genetic tests are crucial for a definite diagnosis. Treatment with cobalamin, L-carnitine, and betaine can effectively reverse the prognosis of MMA in adolescence-onset patients.
