Segmental dystonia caused by levodopa and deep brain stimulation (DBS) in Parkinson′s disease (PD) has been described rarely and may be underrecognized in clinical practice. A case of peak-dose dyskinesia with segmental dystonia, including blepharospasm, jaw dystonia, torticollis, and dystonia in the left upper limb, after bilateral subthalamic nucleus DBS, is reported. The literatures on PD-related dystonia, including dystonia manifestations before and after treatment with medication and DBS, are reviewed to enhance clinicians′ recognition of movement disorders occurring during the treatment of PD and to improve patient outcomes.

Objective To investigate the effects of secukinumab combined with E'xian Huaban decoction on traditional Chinese medicine symptom scores and nailfold microcirculation morphology in patients with plaque psoriasis.Methods A total of 120 patients with plaque psoriasis were selected and randomly divided into monotherapy group(n=60)and combination therapy group(n=60).The monotherapy group received secukinumab treatment,while the combination therapy group was treated with secukinumab plus E'xian Huaban Decoction.Clinical therapeutic efficacy,traditional Chinese medicine symptom scores(including skin lesions,pruritus,rough skin,scales and irritabili-ty),relevant scale[Psoriasisarea and Severity Index(PASI),Dermatology Life Quality Index(DLQI)and Visual Analogue Scale(VAS)]scores,inflammatory factors[interleukin-17(IL-17),interleukin-23(IL-23)and vascular endothelial growth factor(VEGF)]levels and nailfold microcircu-lation morphology(loop tube morphology,blood flow state and loop periphery state)were observed in both groups.Results The overall clinical efficacy rate in the combination therapy group was 95.00％,which was significantly higher than 83.33％ in the monotherapy group(P＜0.05).After treatment,traditional Chinese medicine symptom scores(skin lesions,pruritus,rough skin,scales and irritability),inflammatory factors(IL-17,IL-23 and VEGF)levels,scale(PASI,DLQI and VAS)scores as well as loop tube morphology scores,blood flow state scores and loop periphery state scores were signifi-cantly lower compared to pre-treatment values,and these parameters were significantly lower in the combination therapy group than the monotherapy group(P＜0.05).Conclusion Secukinumab combined with E'xian Huaban Decoction can significantly improve clinical symptoms and signs,and enhancing the clinical therapeutic effect.

Objective:To investigate the correlation between thyroid hormone resistance and hyperuricemia in euthyroid population.Methods:It was a cross-sectional study. A total of 548 euthyroid subjects who were hospitalized or underwent physical examination in the Heart Center and Health Management Center of the First Affiliated Hospital of Tsinghua University from January 2021 to December 2022 were selected. Thyroid function, uric acid, blood lipid and other indicators were collected in the subjects, and thyroid function parameters were calculated: thyroid-stimulating hormone index (TSHI), thyrotropin T4 resistance index (TT4RI), parametric thyroid feedback quantile-based index (PTFQI), free triiodothyronine/free thyroxine (FT3/FT4), the sum activity of peripheral deiodinases (SPINA-GD) and the secretory capacity of the thyroid gland (SPINA-GT). According to uric acid level, the subjects were divided into high uric acid group and normal group, the clinical characteristics and thyroid function parameters of the two groups were compared, the correlation between thyroid hormone resistance and hyperuricemia was further explored.Results:Compared with the normal group, male proportion (94.4% and 52.5%), smoking rate (5.2% and 21.3%), body mass index [(27.10±3.96) and (24.26±3.42) kg/m 2], waist-to-hip ratio [0.90(0.86, 0.94) and 0.86(0.80, 0.91)], serum creatinine [(85.50±12.27) and (73.77±28.79) μmol/L], total cholesterol [(5.08±0.99) and (4.72±0.86) mmol/L], triglyceride [2.10(4.40, 5.59) and 1.14(0.79, 1.67)mmol/L], low-density lipoprotein [(3.19±0.97) and (2.85±0.84) mmol/L] and homocystine [(15.07±9.13) and (12.50±10.85) μmol/L] were all higher in the high uric acid group, and the level of high-density lipoprotein [1.15(1.43, 2.88) and 1.39(1.16, 1.64) mmol/L] was lower (all P<0.05). In the aspect of thyroid hormone and thyroid function parameters, the FT4[16.90(5.40,17.95) and 16.00(14.30,17.80) pmol/L], FT3[5.56(5.25, 5.94) and 5.22(4.81, 5.63) pmol/L], FT3/FT4 [0.34(0.31, 0.37) and 0.32(0.29, 0.36)], TSHI (2.70±0.50 and 2.58±0.60), PTFQI (0.406±0.332 and 0.335±0.353) and SPINA-GD [3.72(3.41, 4.05) and 3.52(3.18, 4.00) ]were all higher in high uric acid group than those in normal group(all P<0.05). Spearman correlation analysis showed that blood uric acid level was positively correlated with FT4 ( r=0.185), FT3 ( r=0.422), FT3/FT4 ( r=0.16), TSHI ( r=0.134), TT4RI ( r=0.09), PTFQI ( r=0.121) and SPINA-GD ( r=0.157) (all P<0.05). Conclusion:In people with euthyroid function, central resistance to thyroid hormone is correlated with hyperuricemia.

AIM: To study the protective effect of fenofibrate on diabetic retinal neurodegeneration and observe its effect on miR-26a-5p and its target gene PTEN in the retinal of diabetic mice.METHODS: Diabetic mice models were established and they were gavaged by fenofibrate. H& E staining and transmission electron microscopy were used to observe the impairments of retinal neurons. Real-time PCR was used to examine the expression of miR-26a-5p, and Western blotting was employed to measure the expression of phosphatase and tensin homologue(PTEN)in the retina of diabetic mice. The expression level of nuclear factor-κB(NF-κB), interleukin-1β(IL-1β)and the morphology of neural tissues were observed.RESULTS: When compared with the diabetic mice, fenofibrate significantly attenuated the damage to retinal ganglion cells and the atrophy of retinal nerve fiber layer. While the level of miR-26a-5p was increased and the levels of PTEN and inflammatory mediators were significantly decreased in the retina of fenofibrate treated diabetic mice, with significant statistical significance(P<0.05).CONCLUSIONS: Fenofibrate protects against diabetic retinal neurodegeneration by upregulating miR-26a-5p and inhibiting PTEN, attenuating the inflammatory response and alleviating retinal cell injury.

International registration of herbal drugs is a necessary prerequisite for the internationalization of Chinese materia medica. North America and European Union occupy an important position in the world herbal drugs market, and their drug administration and quality supervision requirements are relatively complete and progressiveness. By summarizing the definition of herbal drugs in North America and European Union, combing and interpreting the relevant laws, regulations and policy documents, this article constructed the registration path of herbal drugs, and discussed the current status of market registration of herbal drugs in North America and European Union based on the examples of successful marketing of herbal drugs under current application and approval in overseas markets. This article believed that in the future, an internationally matched TCM quality standard evidence system should be built, clinical trials of TCM products in line with international standards should be carried out, standards that are the same or higher than international mainstream GMP should be developed, the registration path of TCM compounds should be explored, and professionals to establish an international registration application team should be recruited to provide theoretical and practical support for China's overseas registration of Chinese TCM products, promote TCM products to enter the world mainstream market, and achieve high-quality development of TCM internationalization.

Objective To investigate the role of miRNAs in maternal amniotic fluid exosomes in development of isolated ventriculomegaly(VM)in fetuses.Methods Amniotic fluid samples were collected from 9 cases of moderate isolated VM and 8 normal control cases to extract exosomal miRNA,and miRNA sequencing technique was used to identify differentially expressed miRNAs between the two groups.Three miRNAs with significant differential expression between the two groups,whose high expression was associated with VM,were selected for verification with RT-qPCR.Dual luciferase reporter assays were used to verify the regulatory effect of miR-122-5p on its predicted target genes AKT3 and CCDC88C.Gene ontology(GO)and KEGG pathway analyses were performed to explore the possible roles of the top 40 significant differential miRNAs in the pathophysiology of VM.Results We identified a total of 272 differentially expressed miRNAs in VM cases,including 43 up-regulated and 229 down-regulated miRNAs.The target genes of these differential miRNAs were associated with DNA and transcription factor binding,transmembrane transporter and nucleic acid binding transcription factor activity,and cell developmental process.These miRNAs were mostly enriched in the MAPK,cGMP-PKG and Wnt signaling pathways.Verification with RT-qPCR showed that miR-122-5p expression level was significantly lower in VM group than in the control group(P<0.05),which was consistent with miRNA sequencing results;let-7b-5p expression level was significantly lower in VM group,which was contrary to miRNA sequencing result.Dual luciferase reporter assays showed that miR-122-5p was not capable of regulating AKT3 or CCDC88C expressions.Conclusions The highly abundant differentially expressed miRNAs in maternal amniotic fluid exosomes play important roles in the occurrence of fetal VM possibly by regulating the MAPK,PI3K-Akt,Wnt and cGMP-PKG signaling pathways.
