Through collecting the existing clinical evidences on acupuncture and moxibustion for urticaria, the distribution of evidence in this field was mapped. A systematic search of Chinese and English literature was conducted in CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library for treatment of urticaria with acupuncture and moxibustion, published up to December 31, 2023 since inception of each database. The research status in this field was summarized using an evidence mapping approach, and methodological quality was assessed. A total of 323 randomized controlled trials (RCTs) and 22 systematic reviews were included. The number of studies on acupuncture and moxibustion for urticaria has been increasing, with a significant rise in recent years. In most RCTs, the study scale was small, and the subjects focused on chronic spontaneous urticaria in adolescents and middle-aged adults, aged 14 to 60 years. Regarding the intervention measures, the single therapy of acupuncture and moxibustion was predominant such as acupoint injection, acupoint embedding thread, and filiform needling. In acupuncture with filiform needles, the commonly used acupoints were Quchi (LI11), Xuehai (SP10), Sanyinjiao (SP6), Zusanli (ST36) and Hegu (LI4). The main outcome measures referred to effectiveness rate, score of disease severity, recurrence rate, laboratory indexes, and score of quality of life; and the short-term effect was evaluated specifically. The overall methodological quality of the included studies was relatively low. It is suggested that the future research should focus on large-scale, multi-center, high-quality clinical trials, optimize the protocols for acupuncture and moxibustion intervention, standardize the outcomes, and draw the attention to the evaluation of long-term efficacy, so as to provide clinical evidences of high certainty for urticaria treated with acupuncture and moxibustion.

OBJECTIVE: To reveal the gap between the evidence of systematic reviews (SRs) and clinical concerns by systematically summarizing the evidence on acupuncture and moxibustion for frozen shoulder and investigating the concerns and needs of clinicians in treatment with acupuncture and moxibustion for this disease. METHODS: The articles of SR and Meta-analysis on acupuncture and moxibustion for frozen shoulder were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase and Cochrane Library, starting from the inception of each database up to December 31st, 2022. Two researchers screened the articles and extracted data independently. Using AMSTAR-2, the methodological quality of the included studies was evaluated. Based on systematic reviews and expert discussion, a questionnaire on clinical concerns of acupuncture and moxibustion for frozen shoulder was developed and distributed to clinicians. The discrepancies between the evidence and clinical concerns were compared from 5 dimensions, including population, interventions, control measures, outcome indicators and review time points. RESULTS: The evidence gaps existed between SRs and clinical concerns. In the existing studies, the needs of personalized treatment were not fully considered in terms of different syndromes/patterns of frozen shoulder and stages of illness, the outcome indicators were not employed properly, the time for outcome measurement was vague, the control groups were set up outside of standardization, and the methodological quality was lower. CONCLUSION It is suggested that future studies should improve the quality of methodology, lay more consideration to different patient groups, optimize outcome indicators and standardize the setting of control groups, so as to better meet the needs of patients and achieve the best match between evidence and clinicians' needs.

Objective The aim of this study was to explore the impact of implant robots on the oral func-tion and aesthetic effects of immediate implant patients in the aesthetic area of anterior teeth.Methods A total of 68 patients with single anterior tooth defects admitted to the hospital from January 2021 to January 2023 were enrolled and divided into a study group of 34 cases and a control group of 34 cases randomly.In the study group,anterior tooth immediate implantation was performed with the assistance of an oral implantation robot,while the control group underwent conventional immediate anterior tooth implantation.The implantation accuracy,postopera-tive bite function,aesthetic restoration,and occurrence of complications were compared between the two groups,and complications were all recorded.Results After final restoration,all patients were followed up for 2 years,and the implant success rate was 100%(68/68 cases).The study group exhibited significantly lower postoperative apical point error and implant angle error compared to the control group(P＜0.05).There was no significant differ-ence in speech clarity,bite pressure,and pain intensity between the two groups(P＞0.05).The ratio of implant bite pressure to that of the contralateral homonymous tooth was higher in the study group than in the control group(P＜0.05).The postoperative pink esthetic score(PES)and white esthetic score(WES)in the study group were higher than those in the control group(P＜0.05).There was no statistically significant difference in the incidence of complications between the two groups(P＞0.05).Patient satisfaction in the study group was higher than that in the control group(P＜0.05).Conclusion The use of oral implantation robots for immediate implantation in the aesthetic zone of anterior teeth resulted in higher intraoperative positioning accuracy and yielded favorable outcomes in postoperative restoration of bite function and aesthetics.

Objective:To investigate the interventional effect of bone marrow mesenchymal stem cell (BMMSC) transplantation with different doses of X-ray irradiation induced hepatic injury in mice.Methods:Eighteen female C57BL/6J mice were randomly divided into 0, 2, and 3 Gy irradiation groups and 0, 2, and 3 Gy transplantation groups. The irradiation group was used as the control and injected with an equal volume of culture medium. The mice in the transplantation group were irradiated with different doses of X-ray irradiation, and BMMSCs were intravenously infused into the bone marrow. The mice were sacrificed for sampling at the end of the 21st day. Mice body weight changes were recorded daily. The changes in the content of peripheral blood lymphocytes, red blood cells, platelets, and hemoglobin were detected by an automatic blood tester. The morphological changes in mice liver tissues were observed by hematoxylin-eosin staining. The serum activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected by a biochemical analyzer. The reduced glutathione contents in liver tissue were detected by the microplate method. The malondialdehyde content in liver tissue was detected by thiobarbituric acid. The content of total superoxide dismutase (T-SOD) in liver tissue was detected by the hydroxylamine method. The expression of the F4/80 protein in liver tissue was detected by the immunohistochemistry method. The protein expression of nuclear transcription factor erythroid 2 related factor 2 (Nrf2) and heme oxygenase 1 (HO-1) in liver tissue was determined by the western blotting method. The mRNA expression of NLRP3, IL-6, and Nrf2 in liver tissue was detected by a real-time quantitative polymerase chain reaction. The multiple-group comparisons were analyzed by factorial analysis of variance. The inter-group comparisons were analyzed by the LSD method for statistical analysis.Results:The contents of peripheral blood lymphocytes, erythrocytes, platelets, and hemoglobin were significantly decreased in the 3 Gy irradiation group than the 0 Gy irradiation group ( P<0.05), while the activities of serum ALT and AST were significantly increased ( P<0.05). The malondialdehyde content, F4/80 protein expression level, nucleotide-binding domain and leucine-rich repeats, nucleotide oligomerization domain-like receptor family, pyrin domain containing 3 (NLRP3), and interleukin 6 mRNA expression levels were significantly increased in liver tissue, while the contents of T-SOD and glutathione, Nrf2 and HO-1 protein expression levels, and Nrf2 mRNA expression level in liver tissue were significantly decreased ( P<0.05). The contents of peripheral blood lymphocytes, red blood cells, platelets, and hemoglobin were significantly increased in the 3 Gy transplantation group than the 3 Gy irradiation group ( P<0.05), while the activities of serum ALT and AST were significantly decreased ( P<0.05). The malondialdehyde content, F4/80 protein expression level, NLRP3 and interleukin-6 mRNA expression levels in liver tissue were significantly decreased ( P<0.05), while the content of T-SOD and glutathione, Nrf2 and HO-1 protein expression levels, and Nrf2 mRNA expression level in liver tissue were significantly increased ( P<0.05). Conclusion:X-ray irradiation at a dose of 3 Gy can induce liver oxidative damage in mice. BMMSC transplantation can improve X-ray irradiation-induced liver oxidative damage in mice, and its mechanism of action may be related to the regulation of the Nrf2/HO-1 pathway.

Osteosarcoma (OS) stood as the most prevalent primary malignant bone tumor among children and adolescents, characterized by its aggressive nature and high propensity for metastasis, thus earning its classification as a highly malignant disease. The primary routes of metastasis in osteosarcoma encompassed hematogenous dissemination (the most common metastasis was lung metastasis) and lymph node involvement, with lymph node metastasis carrying a notably poorer prognosis when contrasted with lung metastasis. However, it was noteworthy that, at that time, clinical practice often overlooked the crucial aspect of conducting regional lymph node screening for newly diagnosed osteosarcoma patients, and there remained a dearth of standardized treatment protocols for osteosarcoma lymph node metastasis. The intricate mechanisms at the heart of osteosarcoma lymph node metastasis primarily revolved around the infiltration of lymphatic vessels by osteosarcoma cells possessing metastatic capabilities and the induction of lymphatic vessel formation by these cells. Nevertheless, it was imperative to underscore that our understanding of the comprehensive mechanisms underpinning the initiation and progression of these processes still remained incomplete. Moreover, following the adaptive proliferation of osteosarcoma cells within regional lymph nodes, there existed a complex biological process that involved a myriad of cytokines and signaling pathways. This process facilitated the metastasis of osteosarcoma cells to distant target organs, most notably the lungs, by virtue of the intimate anatomical relationships between the lymphatic and circulatory systems. Consequently, that comprehensive review sought to provide an all-encompassing exposition on various facets of osteosarcoma lymph node metastasis. These facets included the direct invasion of surrounding lymphatic vessels by osteosarcoma cells, the osteosarcoma cell-induced development of lymphatic vessels through the VEGFC/VEGFR-3 signaling axis, the remodeling of the lymph node microenvironment by osteosarcoma cells via Hsp5B and the Wnt/β-Catenin signaling pathway to ensure their adaptation and survival, the epithelial-mesenchymal transition of osteosarcoma cells promoting metastasis from lymph nodes to the lung, and the utilization of small-molecule compounds in the battle against osteosarcoma lymph node metastasis. The aim was to provide a comprehensive and systematic elucidation of the intricate mechanisms governing osteosarcoma lymph node metastasis and to furnish invaluable insights for the development of therapeutic strategies.

Objective:To analyze the current situation and requirements of education for health technicians in maternal and child health care institutions, and put forward feasible strategies and measures to improve the comprehensive quality and professional level of the talent team of maternal and child health care institutions.Methods:Questionnaire survey was carried out on education needs of health technical staff of 11 maternal and child health care hospitals in 4 provinces (regions), and provincial, municipal and district-level medical institutions. The survey results were recorded by Epidata 3.1. SPSS 22.0 software was used for statistical analysis.Results:A total of 1 678 questionnaires were included in the analysis. A total of 1 313 people received training, accounting for 78.2%. The main reason for not receiving training was that the unit didn't arrange (180 people), accounting for 49.3%(180/365). There were 779 people who had more than 3 days of training, accounting for 59.3%. There were 384 people who were trained in superior general hospitals, accounting for 29.2%, and 268 people were trained in superior maternal and child health institutions, accounting for 20.4%. There were 837 people who learned the content of new professional progress, accounting for 50.8%(837/1 648). According to the interview, there were still some requirements for thematic training, further education, online learning, continuing education and standardized training.Conclusion:Maternal and child health care institutions have accelerated the construction of professional personnel, intensified training, and thoroughly implemented health personnel training programs, established a long-term mechanism, increased funding, improved training content, ensured the quality of training, and made a good job in hierarchical training to meet the learning needs of personnel at all levels. This is of great significance for strengthening the technical personnel of maternal and child health care institutions and improving their service capacity.

The first rate-limiting enzyme of the serine synthesis pathway (SSP), phosphoglycerate dehydrogenase (PHGDH), is hyperactive in multiple tumors, which leads to the activation of SSP and promotes tumorigenesis. However, only a few inhibitors of PHGDH have been discovered to date, especially the covalent inhibitors of PHGDH. Here, we identified withangulatin A (WA), a natural small molecule, as a novel covalent inhibitor of PHGDH. Affinity-based protein profiling identified that WA could directly bind to PHGDH and inactivate the enzyme activity of PHGDH. Biolayer interferometry and LC-MS/MS analysis further demonstrated the selective covalent binding of WA to the cysteine 295 residue (Cys295) of PHGDH. With the covalent modification of Cys295, WA blocked the substrate-binding domain (SBD) of PHGDH and exerted an allosteric effect to induce PHGDH inactivation. Further studies revealed that with the inhibition of PHGDH mediated by WA, the glutathione synthesis was decreased and intracellular levels of reactive oxygen species (ROS) were elevated, leading to the inhibition of tumor proliferation. This study indicates WA as a novel PHGDH covalent inhibitor, which identifies Cys295 as a novel allosteric regulatory site of PHGDH and holds great potential in developing anti-tumor agents for targeting PHGDH.

Osteosarcoma needs to continuously induce angiogenesis to satisfy its own nutritional supply in the process of development. Therefore, the inhibition of osteosarcoma cell-induced angiogenesis as a target has become a research hot in recent years. Currently, vascular inhibitors targeting mRNA-encoded protein have been applied in clinic, but the efficacy is poor. Non-coding RNA (ncRNA) is a type of RNA molecules that do not participate in protein coding. ncRNA can regulate the angiogenesis of osteosarcoma by regulating the secretion of vascular factors such as vascular endothelial growth factor, angiogenin-2 and hypoxia-inducible factor 1 or the interaction between ncRNAs. This article reviews the role of ncRNA in the angiogenesis of osteosarcoma to provide references for clinical targeted therapy strategies for osteosarcoma.
