AIM: To evaluate the effectiveness and safety of compound anisodine combined with laser photocoagulation in the treatment of diabetic retinopathy(DR).METHODS: A prospective cohort study was used to select 80 patients(160 eyes)diagnosed with severe non-proliferative diabetic retinopathy(NPDR)and proliferative diabetic retinopathy(PDR)in Beijing Tongren Hospital, Capital MedTcal University and Beijing Daxing District People's Hospital from May 2023 to July 2023. They were divided into control group(40 cases, 80 eyes)and observation group(40 cases, 80 eyes)by random number table method. The control group only received 532 nm laser panretinal photocoagulation(PRP)treatment, while the observation group received PRP treatment together with superficial temporal subcutaneous injection of compound anisodine. The clinical efficacy, changes in hemorheology, changes in retinal blood vessels, and incidence of adverse reactions in the two groups were observed before and at 2 mo after treatment.RESULTS: The visual acuity, fundus changes and hemorheological parameters of the two groups were analyzed before and after treatment. There were no significant differences in the two groups before treatment(all P>0.05). The best corrected visual acuity of the observation group was better than that of the control group at 2 mo after treatment(P<0.05), and the clinical curative effect of fundus was also better than that of the control group(all P<0.05). The hemorheological indexes of central retinal artery blood flow(peak systolic velocity and end diastolic velocity)in the observation group were higher than those of the control group(all P<0.05), and the blood flow resistance index was lower than that of the control group(P<0.05).CONCLUSION: Compound anisodine combined with 532 nm laser photocoagulation is safe and effective in the treatment of DR, and the visual recovery effect is better.

OBJECTIVE: To observe the clinical effect of Tiaoshen Guben holistic therapy of acupuncture and moxibustion (holistic treatment with acupuncture and moxibustion by adjusting the mind and consolidating the root) on comorbidity of depression and insomnia. METHODS: Twenty-four patients with comorbidity of depression and insomnia were included and treated with Tiaoshen Guben holistic therapy of acupuncture and moxibustion. Acupuncture was applied to Baihui (GV20), Guanyuan (CV4), bilateral Neiguan (PC6), etc. The refined moxibustion therapy was delivered at Zhongwan (CV12), Qihai (CV6), bilateral Yongquan (KI1), etc. Subcutaneous embedding therapy with thumb-tack needle was adopted at bilateral Xinshu (BL15), bilateral Pishu (BL20), etc. The intervention was operated once every other day, 3 treatments a week, and for 6 consecutive weeks. Before and after treatment completion, and in 1 month after treatment, Pittsburgh sleep quality index (PSQI) and Hamilton's depression scale (HAMD-17) were adopted to assess sleep quality and depression symptoms in the patients, respectively. Before and after treatment completion, using functional magnetic resonance imaging (fMRI), the functional connectivity (FC) of locus coeruleus (LC) in brain regions was evaluated; and the levels of serum norepinephrine (NE), cortisol (CORT), adrenocorticotropic hormone (ACTH) and corticotropin releasing hormone (CRH) were detected. RESULTS: Compared with the scores before treatment, PSQI and HAMD-17 scores after treatment completion and in 1 month after treatment were reduced (P<0.01); and strengthened FC was revealed between the right LC and the pars opercularis of the left inferior frontal gyrus, as well as the lateral occipital lobe region. After treatment completion, serum NE was elevated (P<0.01), the levels of CORT, ACTH and CRH were reduced (P<0.01). Before and after treatment completion, the difference in FC between the right LC and the pars opercularis of the left inferior frontal gyrus was negatively correlated with the differences in PSQI score (r = -0.484, P = 0.016) and HAMD-17 score (r = -0.233, P = 0.027). CONCLUSION Tiaoshen Guben holistic therapy of acupuncture and moxibustion can effectively alleviate depression symptoms and improve sleep quality in the patients with comorbidity of depression and insomnia, which is obtained probably through reducing the levels of serum CORT, ACTH and CRH, increasing serum NE, strengthening the FC of the right LC with the pars opercularis of the left inferior frontal gyrus and the lateral occipital lobe region.

Atypical teratoid/rhabdoid tumor (AT/RT) is a rare malignancy located primarily in infratentorial or subcortical areas with a poor prognosis, and rarely in the lateral ventricle with a very poor prognosis. So far, only 6 cases of AT/RT in lateral ventricle have been reported in China. This article reports the diagnosis and treatment of four children with AT/RT in the lateral ventricle, and discusses the clinical manifestations, differentiation and diagnosis, treatment and prognosis of the disease through literature review, in order to improve clinicians' understanding of the disease and reduce missed diagnosis and misdiagnosis.

AIM: To investigate the clinical efficacy of the compound anisodine combined with retinal laser photocoagulation in the treatment of severe non-proliferative diabetic retinopathy(NPDR). METHODS: According to the retrospective study, totally 120 eyes of patients with severe NPDR who admitted to Daxing Teaching Hospital Affiliated to Capital Medical University from May 2023 to July 2023 were selected. The patients were divided into the observation group and the control group according to treatment methods, with 60 eyes in each group. The observation group was treated with panretinal photocoagulation combined with the compound anisodine injection. The control group was only treated with panretinal photocoagulation. The optical coherence tomography angiography(OCTA)and optical coherence tomography(OCT)were used to quantitatively analyze the fundus retinal structure and blood flow. Furthermore, the best corrected visual acuity(BCVA), superficial vascular density(SVD), deep vascular density(DVD), choroidal blood flow density and central macular foveal retinal thickness(CMT)were compared before treatment and at 1 d, 1 and 2 mo after treatment.RESULTS:At 2 mo postoperatively, the rate of visual improvement and the BCVA in the observation group of patients were significantly better than those of the control group, and the incidence of macular edema in the observation group was significantly lower than the control group(P<0.05). The BCVA at 1 and 2 mo after treatment were significantly higher than those before treatment in both groups(P<0.05). The SVD in the observation group was better than the control group at 1 d, 1 and 2 mo after treatment(all P<0.05). The DVD and choroidal flow density in the observation group were better than those of the control group at 1 d after treatment(all P<0.05). The CMT of the observation group was smaller than that of the control group at 1 d after treatment(P<0.05).CONCLUSION:Compound anisodine can effectively improve the fundus microcirculation after panretinal photocoagulation and reduce the incidence of macular edema, thus promoting the visual function.

Coronary artery fractional flow reserve (FFR) is a critical physiological indicator for assessment of impaired blood flow caused by coronary artery stenosis. The wire-based invasive measurement of blood flow pressure gradient across stenosis is the gold standard for clinical measurement of FFR. However, it has the risk of vascular injury and requires the use of vasodilators, increasing the time and overall cost of interventional examination. Coronary imaging is playing an important role in clinical diagnosis of stenotic lesions, evaluation of severity of lesions, and planning of therapies. In recent years, the computation of FFR based on the physiological information of blood flow obtained from routinely collected coronary image data has become a research focus in this field. This technique reduces the cost of physiological assessment of coronary lesions and the use of pressure wires. It is beneficial to strengthen the physiological guidance in interventional therapy. In order to better understand this emerging technique, this paper highlights its implementation principle and diagnostic performance, analyzes practical problems and current challenges in clinical applications, and discusses possible future development.

Objective To investigate the role of microRNA-214-3p (miR-214-3p) in differentiation and proliferation of endothelial progenitor cells (EPCs) induced by cyclic stretch. Methods EPCs were exposed to cyclic stretch at physiological level (with the magnitude of 5%, at a constant frequency of 1.25 Hz) for 24 h by FX-5000T Strain Unit. miRNAs array was performed to identify the expression profiling of miRNAs. Real-time PCR was used to examine the expression levels of miRs. The expression of vascular smooth muscle cells (VSMCs) markers in EPCs was detected by real-time PCR. EPC proliferation was detected by BrdU ELISA assay. After EPCs were transfected with miR-214-3p inhibitor (IN) to knockdown expression of miR-214-3p, the level of VSMC markers expression and EPC proliferation was detected. Results Cyclic stretch significantly decreased miR-214-3p expression, depressed EPC differentiation toward VSMCs, and increased EPCs proliferation. Similarly, transfection with the miR-214-3p inhibitor led to the decreased expression of VSMC markers under static station. Meanwhile, miR-214-3p down-regulation promoted EPC proliferation significantly. Conclusions Physiological cyclic stretch could down-regulate the expression of miR-214-3p in EPCs, depress EPC differentiation towards VSMC and promote EPC proliferation eventually. Therefore, the research findings provide a potential therapeutic strategy for treating vessel injuries.

Genetic studies have revealed a critical role of Distal-homeobox (Dlx) genes in bone formation, and our previous study showed that Dlx2 overexpressing in neural crest cells leads to profound abnormalities of the craniofacial tissues. The aim of this study was to investigate the role and the underlying molecular mechanisms of Dlx2 in osteogenic differentiation of mouse bone marrow stromal cells (BMSCs) and pre-osteoblast MC3T3-E1 cells. Initially, we observed upregulation of Dlx2 during the early osteogenesis in BMSCs and MC3T3-E1 cells. Moreover, Dlx2 overexpression enhanced alkaline phosphatase (ALP) activity and extracellular matrix mineralization in BMSCs and MC3T3-E1 cell line. In addition, micro-CT of implanted tissues in nude mice confirmed that Dlx2 overexpression in BMSCs promoted bone formation in vivo. Unexpectedly, Dlx2 overexpression had little impact on the expression level of the pivotal osteogenic transcription factors Runx2, Dlx5, Msx2, and Osterix, but led to upregulation of Alp and Osteocalcin (OCN), both of which play critical roles in promoting osteoblast maturation. Importantly, luciferase analysis showed that Dlx2 overexpression stimulated both OCN and Alp promoter activity. Through chromatin-immunoprecipitation assay and site-directed mutagenesis analysis, we provide molecular evidence that Dlx2 transactivates OCN and Alp expression by directly binding to the Dlx2-response cis-acting elements in the promoter of the two genes. Based on these findings, we demonstrate that Dlx2 overexpression enhances osteogenic differentiation in vitro and accelerates bone formation in vivo via direct upregulation of the OCN and Alp gene, suggesting that Dlx2 plays a crucial role in osteogenic differentiation and bone formation.
