ObjectiveTo quantitatively analyze and evaluate the content of China's assistive technology industry policies. MethodsBased on the three-dimensional framework of policy "objectives-instruments-intensity", this study examined 101 national-level assistive technology industry policies issued between 2011 and 2024. Policy text analysis was conducted to assess the matching and coordination among policy objectives, policy instruments and policy intensity. Furthermore, the policy modeling consistency (PMC) index model was applied to establish an evaluation system consisting of nine primary indicators and 35 secondary indicators, and six key policies were quantitatively evaluated. ResultsThe policy objectives mainly focused on optimizing the industrial development structure, also emphasized supportive environments for industrial development and the enhancement of innovation capacity. Policy instruments were dominated by supply-oriented and environment-oriented instruments, supplemented by demand-oriented instruments, aiming to strengthen technological foundations and competitiveness, promote standardized development, and facilitate industrial development and upgrading. Regarding the matching between policy objectives and instruments, multiple instruments were adopted to support different objectives, with different priorities. In terms of the matching between policy objectives and policy intensity, policies mainly emphasized improving the accessibility of assistive technology products and meeting the rehabilitation needs of different populations. Regarding the matching between policy instruments and policy intensity, supply-oriented instruments were more frequently adopted and showed higher policy intensity, indicating strong governmental efforts to optimize production factor allocation and enhance the capacity of market entities. The average PMC index score was 6.45, indicating relatively high policy quality, strong internal consistency, stable policy orientation, and clear objectives. The PMC scores for policy evaluation and policy instrument dimensions were relatively high, while some policies showed relatively narrow objectives. ConclusionChina's assistive technology industry policies demonstrate relatively high quality. Future policy development should further strengthen industrial innovation capacity, optimize the structure of policy instruments, and improve the alignment between policy objectives and instruments.

Objective:To investigate the clinical characteristics of a family with maturity-onset diabetes of the young type 3(MODY3) and assess its association with the novel HNF1A-c.47T>A variant.Methods:A genetic pedigree of the MODY3 family was constructed, and clinical data were collected. Whole-exome sequencing combined with Sanger sequencing was used, followed for familial co-segregation analysis. Bioinformatics tools, including multiple sequence alignment–based conservation analysis and protein structural prediction, were conducted to validate the association between the novel HNF1A-c.47T>A variant and MODY3.Results:Seven MODY3 patients were diagnosed in this family, all harboring the HNF1A-c.47T>A heterozygous variant. AlphaFold2 protein structure prediction indicated that the HNF1A-c.47T>A variant altered the conformation of the first pair of α-helices within the protein dimerization domain.Conclusion:Based on co-segregation analysis, sequence conservation assessment, protein structure prediction, and classification based on American College of Medical Genetics and Genomics(ACMG) Guidelines, the HNF1A-c.47T>A variant was determined to be pathogenic for MODY3. This study reports this novel pathogenic variant, expanding the mutational spectrum of MODY3. By revealing its disruptive effect on the protein dimerization domain, the findings provide a potential molecular basis for the diagnosis and management of patients carrying similar variants.

Hepatocellular carcinoma is a kind of cancer with a strong invasion, a high incidence rate and mortality, and a poor prognosis. At the time of diagnosis, most patients are already in the advanced stages of a tumor and have lost the chance for radical surgical treatment. Advanced hepatocellular carcinoma treatment has a gradual transition from systemic chemotherapy to targeted therapy, immunotherapy, and combination therapy, especially immune checkpoint inhibitor-based immunotherapy combination therapy, such as combination with bevacizumab monoclonal antibodies and other drugs, or combination with TACE, HAIC, radiotherapy, ablation, and other treatment methods. Combination therapy has significant synergistic effects and thus has already become a future treatment trend for hepatocellular carcinoma. An immunotherapy-based combination therapy plan will run through the whole process of systemic therapy, which is expected to bring better survival benefits to patients with hepatocellular carcinoma. This article reviews the latest research progress in aspects of the first-line treatment of advanced hepatocellular carcinoma.

Objective:To investigate the relationship between thyroid stimulating hormone (TSH) level and thyroid peroxidase antibody (TPOAb) status in the first trimester on pregnancy outcomes.Methods:A total of 2 095 pregnant women with complete clinical data from department of pregnancy endocrinology or department of obstetrics in Dongying People′s Hospital from January 1, 2018 to November 31, 2019.According to the TSH level detected before 12 + 6 weeks of gestation, all pregnant women were divided into normal TSH (0.1 μIU/ml≤TSH< 2.5 μIU/ml), high TSH (2.5 μIU/ml≤TSH≤4.0 μIU/ml), sub-clinical hypothyroidism during gestation (4.0 μIU/ml0.05). Multivariate logistic regression analysis of gestational diabetes mellitus and preterm delivery showed that the risk of gestational diabetes mellitus was significantly increased in group F compared with the control group. Age, gestational status, and TPOAb positivity were risk factors for gestational diabetes. The risk of premature birth in group D, group E and group F was higher than that in the control group [odds ratio ( OR)>1]. Age and TPOAb positivity were risk factors for preterm delivery in pregnant women ( OR>1, P<0.05). Conclusions:TPOAb positive in early pregnancy combined with subclinical hypothyroidism in pregnancy will increase the risk of gestational diabetes, while TPOAb positive in early pregnancy combined with TSH on the high side or subclinical hypothyroidism in pregnancy will increase the risk of premature delivery, so the management of such pregnant women should be strengthened and active treatment should be given if necessary.

Objective: To determine the optimal dose of dexmedetomidine required to prevent nausea and vomiting when used for postoperative analgesia after gynecological laparoscopic surgery. Methods: A total of 135 patients, aged 18-60 yr, weighing 52-80 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective gynecological laparoscopic surgery, were divided into 3 groups (n=45 each) using a random number table method: control group (group C), dexmedetomidine 1 μg/kg group (group D₁) and dexmedetomidine 2 μg/kg group (group D₂). Immediately after anesthesia induction, dexmedetomidine 0.4 μg·kg^-1·h^-1 was injected intravenously until 30 min before the end of surgery in all the patients.When the patient was fully awake at the end of surgery, the tracheal tube was removed, and patients were sent to postanesthesia care unit and received patient-controlled intravenous analgesia (PCIA). The PCIA solution contained sufentanil 1.2 μg/kg and dezocine 20 mg in 100 ml of 0.9% normal saline.The PCIA pump was set up with a 0.5 ml bolus dose, a 15 min lockout interval and background infusion at a rate of 2 ml/h.Dexmedetomidine 1 and 2 μg/kg were added to PCIA solution in group D₁ and group D₂, respectively.The occurrence of nausea and vomiting was recorded in postanesthesia care unit stay period (P₁) and in 0-12 h (P₂), 12-24 h (P₃), 24-36 h (P₄) and 36-48 h (P₅) periods after patients returned to the ward.Ramsay sedation score was recorded at 12, 24, 36 and 48 h after patients returned to the ward.When visual analogue scale score >3, patients were told to press PCIA.Patients were followed up for 48 h after surgery, and patients′ satisfaction, pressing times of PCIA and occurrence of pruritus, respiratory depression, bradycardia and dizziness were recorded. Results: Compared with group C, the incidence of nausea was significantly decreased in P₂ period, and the pressing times of PCIA were reduced in P_{2, 3} period in D₁ and D₂ groups (P<0.05). There was no significant difference in Ramsay sedation score at each time point, patients′ satisfaction and incidence of bradycardia among the three groups (P>0.05). No patients developed pruritus, respiratory depression or dizziness in the three groups. Conclusion The optimal dose of dexmedetomidine required to prevent nausea and vomiting is 1 μg/kg when used for postoperative analgesia after gynecological laparoscopic surgery.
