Objective To investigate the frequency of therapy-oriented oral radiation in Nanping, China and its distribution, and to provide a basis for the rational application of therapy-oriented oral radiation and the effective allocation of resources in Nanping. Methods A questionnaire was designed to investigate the frequency of therapy-oriented oral radiation in all oral radiation diagnosis and treatment institutions in Nanping. Results In 2021, there were 54 oral radiation diagnosis and treatment institutions and 79 oral radiation machines in Nanping. The total frequency of therapy-oriented oral radiation was 61593 visits and the radiation frequency was 19.54 visits per thousand patients. The average annual frequency of medical institutions at all levels was 721.87 to 3713.25 visits per institution; the male-to-female composition ratio of frequency of therapy-oriented oral radiation in December 2021 was 50.5%:49.5%. The proportion of radiation frequency of different devices was as follows: 38.7% (intraoral dental film), 46.5% (oral panorama), 10.3% (oral computed tomography [CT]), and 4.5% (cranial photography). The proportion of radiation frequency in patients of different ages was as follows: 17.1% (0−15 years), 48.2% (15−40 years), and 34.7% (over 40 years). The frequency of therapy-oriented oral radiation grew by 77.43%, 35.18%, and 8.16% every two years from 2015 to 2021, respectively. Conclusion The frequency level of therapy-oriented oral radiation in Nanping is at the level of Class II health care. The distribution of therapy-oriented oral radiation is highly unbalanced and is related to the level of economic development. Private healthcare institutions are growing rapidly, and public healthcare institutions of grade two and above occupy the main healthcare resources. The oral panorama accounts for the most, cranial photography accounts for the least, and oral CT is the fastest-growing portion. Therapy-oriented oral radiation is predominantly performed in the young and middle-aged populations, regardless of sex. Except for intraoral dental films, the general trend is upward.

AIM: To evaluate the efficacy of high-intensity focused ultrasound cyclo plasty(UCP)in the treatment of glaucoma and to investigate related influencing factors.METHODS: The study involved a total of 110 patients(134 eyes)who received UCP treatment between January 2019 and January 2022 at three medical centers: Tianjin Eye Aier Eye Hospital, Chongqing Aier Eye Hospital, and Chongqing Nanping Aier Eye Hospital. Patients were classified into three categories: primary angle-closure glaucoma, primary open-angle glaucoma, and secondary glaucoma. Best corrected visual acuity, intraocular pressure, and the usage of anti-glaucoma medications, etc., were recorded at 6 and 12 mo postoperatively.RESULTS: After 6 months of the UCP procedure, statistically significant differences in intraocular pressure were observed across all groups(all P<0.05). At 12 mo postoperatively, intraocular pressure of the primary angle-closure and primary open-angle glaucoma groups showed differences(all P<0.05). Notably, there were no significant changes in visual acuity at either the 6 or 12 mo compared to preoperative values across all patient groups(all P>0.05). Furthermore, the study identified a statistically significant correlation between the changes in intraocular pressure at 6 mo and factors such as age, history of previous glaucoma surgery, baseline white-to-white(corneal diameter), and the extent of UCP treatment(all P<0.05).CONCLUSION: The UCP procedure has been demonstrated to effectively lower intraocular pressure in patients with glaucoma. The efficacy appears to be influenced by variables including patient age, previous glaucoma surgery history, baseline white-to-white(corneal diameter), and the scope of UCP treatment. Importantly, UCP treatment did not adversely affect visual acuity, underscoring its favorable safety profile.

Objective:To evaluate and summarize the best evidence on fatigue management in children with tumors both domestically and internationally, providing reference for medical and nursing staff to improve fatigue symptoms in children.Methods:The evidence on fatigue management in children with tumors, including best practices, recommended practices, guidelines, systematic reviews, evidence summaries, and expert consensus, was systematically retrieved from clinical decision support systems, guideline websites, professional association websites, and databases both domestically and internationally. The search period was from database establishment to April 2023. Two researchers independently conducted literature quality evaluation and evidence extraction.Results:A total of 17 articles were included, including four guidelines and 13 systematic reviews. Thirty-two best pieces of evidence were extracted from six aspects of assessment and screening, identification of risk factors, health education, exercise intervention, medication intervention, and other interventions of fatigue in children with tumors.Conclusions:The best evidence for fatigue management in children with tumors is summarized, which can provide a basis for medical and nursing staff to improve their fatigue symptoms. It is recommended that medical and nursing staff combine clinical context, professional opinions, and patient wishes to screen the best evidence and develop personalized fatigue management programs.

Psoriasis is a chronic inflammatory skin disease with key pathological features,including hyperpro-liferation and abnormal differentiation of epidermal keratinocytes,infiltration of immune cells,and abnormal angiogene-sis.These pathological processes collectively contribute to the condition's hallmark clinical manifestations of psoriasis,such as erythema,scaling,and pruritus.Nuclear receptors are a class of ligand-dependent transcription factors that form a superfamily.By interacting with their ligands and co-factors,nuclear receptors regulate gene expression and play critical roles in lipid metabolism,glucose metabolism,cholesterol metabolism,embryonic development,and cellular proliferation and differentiation.Nuclear receptors are also involved in the pathogenesis of psoriasis through their regulation of gene ex-pression and cellular functions,particularly in relation to epidermal proliferation and immune-mediated inflammatory re-sponses.This review will provide a brief overview of the roles and mechanisms of nuclear receptors in psoriasis.

Background::Pulmonary arterial hypertension (PAH) is characterized by excessive proliferation of small pulmonary arterial vascular smooth muscle cells (PASMCs), endothelial dysfunction, and extracellular matrix remodeling. G protein-coupled receptor kinase 2 (GRK2) plays an important role in the maintenance of vascular tone and blood flow. However, the role of GRK2 in the pathogenesis of PAH is unknown.Methods::GRK2 levels were detected in lung tissues from healthy people and PAH patients. C57BL/6 mice, vascular smooth muscle cell-specific Grk2-knockout mice ( Grk2?SM22), and littermate controls ( Grk2flox/flox) were grouped into control and hypoxia mice ( n = 8). Pulmonary hypertension (PH) was induced by exposure to chronic hypoxia (10%) combined with injection of the SU5416 (cHx/SU). The expression levels of GRK2 and Yes-associated protein (YAP) in pulmonary arteries and PASMCs were detected by Western blotting and immunofluorescence staining. The mRNA expression levels of Grk2 and Yes-associated protein ( YAP) in PASMCs were quantified with real-time polymerase chain reaction (RT-PCR). Wound-healing assay, 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay, and 5-Ethynyl-2′-deoxyuridine (EdU) staining were performed to evaluate the proliferation and migration of PASMCs. Meanwhile, the interaction among proteins was detected by immunoprecipitation assays. Results::The expression levels of GRK2 were upregulated in the pulmonary arteries of patients with PAH and the lungs of PH mice. Moreover, cHx/SU-induced PH was attenuated in Grk2?SM22 mice compared with littermate controls. The amelioration of PH in Grk2?SM22 mice was accompanied by reduced pulmonary vascular remodeling. In vitro study further confirmed that GRK2 knock-down significantly altered hypoxia-induced PASMCs proliferation and migration, whereas this effect was severely intensified by overexpression of GRK2. We also identified that GRK2 promoted YAP expression and nuclear translocation in PASMCs, resulting in excessive PASMCs proliferation and migration. Furthermore, GRK2 is stabilized by inhibiting phosphorylating GRK2 on Tyr86 and subsequently activating ubiquitylation under hypoxic conditions. Conclusion::Our findings suggest that GRK2 plays a critical role in the pathogenesis of PAH, via regulating YAP expression and nuclear translocation. Therefore, GRK2 serves as a novel therapeutic target for PAH treatment.

Objective: This study examined the impact of PRRSV NADC30-like strains on pig farms in Fujian, China. Methods: The effectiveness of strategic management protocols, including herd closure, medication programs, monitoring of processing fluids (pig testicular fluid), and collection of production data, were analyzed. The prevalent strain in the pig farm was identified as a NADC30-like strain of the PRRSV through genetic sequencing comparison analysis. Results: The quantitative real-time reverse-transcription polymerase chain reaction results showed that the PRRSV cycle threshold (Ct) values of the processing fluid samples were relatively low from September to early October 2021. After implementing the intervention measures (October 2021), the Ct value increased gradually and reached a negative in March 2022, lasting six months. In addition, the average survival rate of the pigs before the intervention was 84.1%, while the average survival rate after the intervention was 93.1%. Conclusions and Relevance: The use of 12-month intervals for pig herd closure, drug planning, and other strategic management agreements (multi-point production and active monitoring of production data, McREBEL) helped stabilize the subsequent pig farm production, providing a basis for clinical disease prevention and control.

Objective : To investigate the effect of adeno⁃associated virus ( AAV) delivery of short hairpin RNA ( shRNA) against the Ptger3 gene in the lateral parabrachial nucleus (LPB) on the fever induced by microinjection of prostaglandin E2 (PGE2 ) into the LPB and the intraperitoneal injection of lipopolysaccharide (LPS) . Methods: AAV2⁃shRNA⁃Ptger3(EP3) ⅣEGFP ( shRNA⁃EP3) and AAV2⁃ CMV⁃ EGFP ( shRNA⁃control) viruses were constructed and transfected the rat LPB by stereotaxic injection. Four weeks later, the transfection efficiency of AAV viruses was observed by fluorescence microscopy , and the knockdown efficiency was determined by real⁃time PCR of EP3 receptor mRNA on the LPB. The effects of microinjection of saline or PGE2 in the LPB or intraperitoneal injection of LPS on body temperature (Tcore ) and energy expenditure (EE) of shRNA⁃control group and shRNA⁃EP3 group were monitored using an animal monitoring system with temperature telemetry. Results : AAV virus transfecnificant difference in basal body temperature between shRNA⁃control group and shRNA⁃EP3 group. Tcore and EE were briefly and slightly increased after microinjection of saline in the LPB , but there was no significant difference between the two groups. Compared with the shRNA⁃control group , the febrile response induced by LPB PGE2 was attenuated in the shRNA⁃EP3 group (P < 0. 05) . Furthermore , the knockdown of EP3 receptor of LPB also attenuated the LPS⁃induced fever, and the Tcore 5. 5 h post⁃LPS in the shRNA⁃EP3 rats increased compared with the baseline (P < 0. 05) , which was lower than that in the shRNA⁃control rats ( P < 0. 01) . Conclusion EP3 receptor knockdown in LPB attenuates the febrile response induced by microinjection of PGE2 in the LPB and intraperitoneal injection of LPS , suggesting that EP3 receptors of LPB mediate the pyrogenic action of LPB PGE2 and partly participate in LPS⁃induced fever.
