OBJECTIVE: To reveal the research status of fire needle by analyzing its patent applications, so as to provide reference for the development of fire needle equipment and the promotion of this therapy. METHODS: By searching the incoPat global patent database, from its inception to December 29th, 2024, the patent data on fire needle was collected. The patent analysis was employed on patent application trends, geographical distribution, patent types, current legal status, applicants and inventors, overall technical composition and distribution of applicable diseases. With the help of incoPat's "shared value" evaluation model, the technical efficacy value of patent was comprehensively measured from 3 dimensions, i.e. technical stability, technological advancement and protection scope. Using SWOT analysis, the matrix of strengths, weaknesses, opportunities and threats of fire needle technique was constructed, and then its development trend was analyzed systematically. RESULTS: A total of 346 patents were included, comprising 23 granted invention patents (6.65%), 219 utility model patents (63.29%), and 157 patents were in an effective state of validity (45.38%). The number of fire needle patent applications showed a growing trend since 2013 and peaked in 2021. The top 3 provinces and cities in terms of the number of applications were Guangdong, Beijing and Shandong. Existing patents focus on improving convenience, reducing complexity, enhancing safety and increasing efficiency; and are specialized in treatment of dermatological diseases. The results of patent research on fire needle show the application of updated materials, invention of equipment and expansion of applicable diseases. However, there are still some limitations such as technical complexity, high cost, lack of composite talents, lack of awareness of patent maintenance and insufficient international promotion. CONCLUSION Multiple strategies are proposed on the development of fire needle therapy, i.e. enhancing financial support and expanding the number of diseases, giving full play to regional characteristics and advantages to promote resource sharing, deepening the integration of industry, research and education to improve the quality of patents, strengthening supervision to reduce low-quality patents, and carrying out high-level research to promote technical standardization and internationalization, and enhance global competitiveness.

X-linked adrenoleukodystrophy(X-ALD) is an inherited progressive neurometabolic disorder caused by mutations in the ATP-binding cassette subfamily D member 1(ABCD1) gene. The encoded ALD protein dysfunction leads to the accumulation of very-long-chain fatty acids(VLCFA). X-ALD is classified according to its clinical characteristics into childhood cerebral ALD, adolescent cerebral ALD, adult cerebral ALD, adrenomyeloneuropathy(AMN), pure adrenocortical insufficiency, and an asymptomatic phenotype, all of which can present with a variety of neurologic manifestations. In this study, we retrospectively analyzed the clinical manifestations, laboratory findings, genetic test results, and follow-up data of four patients with X-ALD, and investigated the clinical features and pathogenicity of the identified gene mutations. All four patients initially presented with adrenocortical insufficiency(Addison′s disease) and received glucocorticoid replacement therapy. Subsequently, all developed neurologic signs and symptoms with rapid progression. The final diagnosis was confirmed based on elevated VLCFA levels, brain magnetic resonance imaging(MRI) findings, and genetic analysis. Notably, a deletion mutation in Exon 10 of the ABCD1 gene was identified in one case for the first time. We report four cases of X-ALD presenting with adrenocortical insufficiency as the initial symptom, and briefly review the relevant literature to analyze the relationship between linical phenotypes and genetic loci, aiming to provide a reference for early diagnosis and treatment of the disease, and to reduce the risk of misdiagnosis and missed diagnosis.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the current status of occupational internal exposure of nuclear medicine staff performing 131I treatment, and explore the related influence factors, so as to provide a basis for protection against internal exposures. Methods:A survey was conducted using cluster random sampling method to ascertain all the nuclear medicine staff involved in 131I treatment in nuclear medicine hospitals in Hubei province for the years 2021 to 2023. The in vitro monitoring mesurement was made of the 131I activity in thyroid by using portable gamma spectrometer, and the committed effective dose was estimated. Results:The positive detection rate of 131I in treatment staff was between 18.75% and 21.12%, with an average of 20.08%. The highest value found in cleaning and nursing staff in iodine therapy workplaces. The detection rate found in two hospitals were up to 75.61% and 64.71%, respectively. The detection rate was positive for the three consecutive years. There was no statistically significant difference in the committed effective dose between different treatment positions, and the level of internal exposure was lower than the external exposure arising from nuclear medicine practice. Factors affecting detection rate of 131I in thyroid included the amount of 131I used for treatment, and disorder type for treatment, 131I dose, use or otherwise of automated radiopharmaceutical dispenser, and ventilation in treatment rooms. Conclusions:Continuous attention should be paid to the internal exposure of nuclear medicine staff for use of 131I for treatment. Ventilation should be provided regularly, as required, to the 131I treatment rooms and active rooms and the staff should wear masks during the relevant working processes.

Objective: To assess the presence of vector-borne pathogens [including Zika virus (ZIKV), dengue virus (DENV), chikungunya virus (CHIKV), and Plasmodium (PLAS)] among voluntary blood donors in Wenshan Zhuang and Miao Autonomous Prefecture (referred to as Wenshan), so as to provide a basis for formulating blood safety-related strategies. Methods: Blood samples from voluntary blood donors in Wenshan from June to August 2022 to 2024 were selected. Real-time fluorescent quantitative reverse transcription polymerase chain reaction (RT-qPCR) was used to test 20 426 samples for ZIKV RNA, DENV RNA, and CHIKV RNA; and 19 765 samples were tested for PLAS DNA. Results: All 20 426 samples tested for ZIKV RNA, DENV RNA, and CHIKV RNA were negative; similarly, all 19 765 samples tested for PLAS DNA were negative. Conclusion: The risk of ZIKV, DENV, CHIKV, and PLAS infection among voluntary blood donors in Wenshan is relatively low. Routine surveillance for these pathogens as endemic diseases is not currently warranted. It is recommended to adjust the screening strategy based on the dynamic situation of local epidemiology control and prevention.

Objective: To systematically analyzes the impact of blood donor characteristics on red blood cell (RBC) quality and transfusion outcomes, and to provide a scientific basis for optimizing donor selection criteria and developing personalized transfusion strategies. Methods: A literature search was conducted across electronic databases including CNKI, VIP, Wanfang Data, PubMed, and Embase using combinations of keywords such as "donor characteristics", "blood storage lesion", "blood quality", and "transfusion outcomes" for summary and analysis. Results: Factors associated with the blood donor characteristics including demographic characteristics (sex, age, body mass index), lifestyle habits (smoking, alcohol consumption, exercise), and dietary or pharmacological exposures significantly influence blood storage stability and transfusion efficacy by modulating erythrocyte metabolism, oxidative stress levels, and immune properties. Conclusion: The complexity and diversity of the blood donor characteristics are associated with blood quality and transfusion outcomes. Future efforts should focus on refining donor selection criteria and establishing personalized transfusion strategies to enhance blood product quality and improve patient outcomes.

Objective:To investigate the effects of electroacupuncture on neuroinflammation in rats with postherpetic neuralgia (PHN) by regulating advanced glycation end products (AGE) and its receptor (RAGE) signaling pathway.Methods:Ten healthy male SD rats were randomly selected as the control group, and the remaining 30 SD rats were used to induce PHN model by resin toxin (RTX). Thirty SD rats were randomly divided into model group, positive drug group and electroacupuncture group, with 10 rats in each group. Intervention was conducted on the 7th day of modeling. The electroacupuncture group intervened with "Yanglingquan"(GB34) and "Huantiao"(GB30); the positive drug group was intragastrically administered with pregabalin suspension 27 mg/kg, once a day for 1 week; the control group and model group were not treated. The paw retraction threshold (PWMT) and paw retraction latency (PWTL) were measured before modeling and on the 7th, 14th, 21st and 28th days after modeling; histopathological changes of spinal cord were observed by HE staining; the levels of TNF-α, IL-1β and IL-6 in spinal cord tissue were detected by ELISA; the expressions of AGE-RAGE signaling pathway related proteins in spinal cord was detected by Western blot.Results:Compared with the model group, the degree of atrophy and inflammatory infiltration of spinal cord neurons in the positive drug group and electroacupuncture group were reduced. The PWMT value in the positive drug group increased ( P<0.05), and the PWTL value decreased ( P<0.05); compared with the model group, the levels of TNF-α, IL-1β and IL-6 in the spinal cord tissue of the electroacupuncture group and the positive drug group decreased ( P<0.05), and the expressions of AGE, RAGE, p-ERK1/2/ERK1/2, JNK, p-NF-κB/NF-κB and AP-1 decreased ( P<0.05); compared with the positive drug group, the levels of TNF-α, IL-1β and IL-6 in the spinal cord tissue of the electroacupuncture group decreased ( P<0.05), and the protein expressions of AGE, RAGE, p-ERK1/2/ERK1/2, JNK, p-NF-κB/NF-κB and AP-1 decreased ( P<0.05). Conclusion:Electroacupuncture can improve neuroinflammation in PHN rats, the mechanism of which may be related to the regulation of AGE-RAGE mediated pro-inflammatory signaling pathway.

ObjectiveTo observe the clinical efficacy of acupuncture combined with bloodletting and cupping in the treatment of chronic spontaneous urticaria（CSU） and to explore its potential mechanisms of action. MethodsSeventy CSU patients were randomly divided into loratadine group and acupuncture + bloodletting group， with 35 patients in each group. The loratadine group received oral loratadine tablets， 10 mg once daily in the evening. The acupuncture + bloodletting group received acupuncture at Zhongwan （CV 12）， Guanyuan （CV 4）， Tianshu （ST 25）， Zusanli （ST 36）， Sanyinjiao （SP 6）， Xuehai （SP 10）， Quchi （LI 11）， Hegu （LI 4）， Taichong （LR 3）， Baihui （GV 20）， and Shenting （GV 24）， once daily，along with bloodletting and cupping at Dazhui （GV 14） and Geshu （BL 17）， every other day. Both groups were treated for 4 weeks. The 7-day urticaria activity score（UAS7） was assessed before and after the treatment， and levels of serum immunoglobulin E （IgE）， interleukin-4 （IL-4）， interleukin-5 （IL-5）， eosinophil cationic protein （ECP）， plasma tissue factor （TF）， activated factor Ⅶ （FⅦa）， prothrombin fragment 1+2 （F1+2）， D-dimer （D-D） and complement component 5a （C5a） were detected. ResultsA total of 65 patients were included in the final analysis， 32 in the loratadine group and 33 in the acupuncture + bloodletting group. Before treatment， there was no significant difference in UAS7 score， serum IgE， IL-4， IL-5， ECP levels， or plasma TF， FⅦa， F1+2， D-D， C5a levels between groups （P＞ 0.05）. After treatment， both groups showed significant reductions in UAS7 score， serum IgE， IL-4， IL-5， and plasma TF， FⅦa， F1+2， D-D， and C5a levels compared to those before treatment （P＜0.01）. However， after treatment， there was no significant difference in UAS7 score and serum ECP， IgE， IL-4， IL-5 levels between groups （P＞0.05）. The acupuncture + bloodletting group showed lower plasma TF， FⅦa， F1+2， D-D and C5a levels compared to the loratadine group （P＜0.05 or P＜0.01）. ConclusionAcupuncture combined with bloodletting and cupping can effectively improve the skin symptoms of CSU patients and reduce the levels of inflammatory factors. The potential mechanism of action may involve the regulation of the coagulation-complement-mast cell activation axis， thereby inhibiting mast cell degranulation.

BACKGROUND:In recent years,brain-computer interface technology has emerged as a transformative approach in human-computer interaction by recognizing movement intentions to control external devices.This technology has been utilized in the treatment of lower limb functions after stroke,offering new hope for the rehabilitation of stroke patients.OBJECTIVE:To analyze and summarize the application of brain-computer interface technology in the rehabilitation of lower limb motor functions in stroke patients in recent years,and to explore the clinical application value of brain-computer interface technology in the functional rehabilitation of the lower limbs in stroke patients.METHODS:A literature search in CNKI and PubMed was conducted using"stroke,brain-computer interfaces,lower extremity"as search terms in Chinese and English,respectively,with the search time range set from January 2014 to June 2024.RESULTS AND CONCLUSION:Brain-computer interfaces hold promising prospects for the recovery of lower limb motor function in stroke patients,and their application in the field of rehabilitation medicine is continuously expanding.However,the underlying mechanisms have not yet been fully elucidated.Moreover,there are certain limitations in the acquisition of electroencephalogram signals from patients,resulting in reduced precision for brain-computer interface systems in recognizing limb movements.Current decoding methods also exhibit constraints in identifying the gait cycle and fail to accurately locate voluntary movements of the various joints and muscles of the lower limbs,impeding the application of brain-computer interface technology.Subsequent research should focus on elucidating the neural mechanisms by which brain-computer interface technology facilitates the recovery of lower limb motor functions in stroke patients,refining the technologies and devices for extracting brain motor signals,and formulating multimodal feedback for individual patients to realize more effective motor rehabilitation.These advances could propel the development of brain-computer interface technology in the field of lower limb motor function recovery,ameliorate patient rehabilitation outcomes,and elevate the quality of life.
