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.

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.

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.

BACKGROUND:As a bone replacement and filling material,calcium phosphate stone bone cement has good biocompatibility,bone conductivity,and other advantages,especially its better biodegradability compared to other calcium phosphate bone cements.It has important application value in bone repair.However,due to its limitations such as insufficient mechanical properties,fast solidification reaction,and poor injection performance,it is currently only suitable for the repair of non weight-bearing bone. OBJECTIVE:To explore the modification of brushite cements with bioactive ions(metal and non metal ions)to expand its application range. METHODS:The author used PubMed,ScienceDirect,CNKI,and WanFang to search the literature published between 2018 and 2023 with the search terms"metal ion,iron,copper,strontium,magnesium,zinc,non-metal ion,modification,bone,brushite cements"in Chinese and"metal ion,iron,Fe,copper,Cu,strontium,Sr,magnesium,Mg,zinc,Zn,non-metal ion,modification,bone,brushite cements"in English.After reading titles and abstracts,the articles were initially screened,and irrelevant and duplicate articles were excluded.Finally,64 articles were included for review. RESULTS AND CONCLUSION:(1)Bioactive ions affect the hydration process of calcium phosphate bone cement.Different ions are substituted by ions and incorporated into the crystal structure of calcium phosphate bone cement,changing the crystal morphology of the cement and causing changes in physical and chemical properties such as setting time,injectability,and compressive strength.(2)Ionic modified calcium phosphate bone cement produces different ion release effects due to different crystal structures.Different types of ions have properties such as promoting angiogenesis/osteogenesis,antibacterial,anti-tumor,etc.In addition,calcium phosphate bone cement has good biodegradability,which has great advantages for the performance of various ions.(3)The physicochemical properties of calcium phosphate bone cement modified with different ions are as follows:iron,copper,strontium,magnesium,zinc,silver,and cobalt can prolong the setting time.Strontium,and magnesium can improve injection performance.Copper,strontium,magnesium,silver and silicon can enhance compressive strength.The ions that can simultaneously improve the three physical and chemical properties of calcium phosphate bone cement include strontium and magnesium.Good physical and chemical properties are a prerequisite for clinical application,so improving the setting time,injectability,compressive strength,and other properties of calcium phosphate bone cement with ions is of great significance for the research and application of bone cement.(4)The biological properties of calcium phosphate bone cement modified with different ions are as follows:copper,strontium,magnesium,zinc,cobalt,lithium,selenium,and silicon have promoting angiogenesis/osteogenic effects.Iron,copper,magnesium,zinc,and silver have antibacterial properties.Magnesium ions have anti-inflammatory properties.Copper and selenium have anti-tumor properties.(5)In summary,magnesium ions can improve the setting time,injectability,and compressive strength of calcium phosphate bone cement,while also promoting neovascularization/osteogenesis,antibacterial properties,and have good application prospects for the treatment of bone defects with concurrent infections.In addition,copper also has anti-tumor properties,so copper ions have great potential in the treatment of bone defects caused by infections and tumors.However,relevant research is still in the basic research stage,and the effects of different ion doping concentrations and synthesis conditions on the physicochemical properties of calcium phosphate bone cement need to be further explored.At the same time,the impact of biological properties also needs to be studied and observed for a longer period of time.

Objective To accurately encode pelvic organ prolapse and ensure data accuracy.Methods ICD-10 coding analysis was performed in combination with the professional knowledge of the International Classification of Diseases(ICD-10)and specific clinical cases of pelvic organ prolapse.Results Vaginal anterior wall prolapse,regardless of severity,was encoded as N81.1;vaginal posterior wall prolapse,regardless of severity,as N81.6;uterine prolapse grade Ⅰ and Ⅱ,regardless of the presence or absence of vaginal anterior and posterior wall prolapse,as N81.2;uterine prolapse grade Ⅲ,whether the prolapse of the anterior and posterior vaginal walls is combined,or what level of the severity of the prolapse,as N81.3;cervical prolapse staging,regardless of severity or presence of vaginal anterior and posterior wall prolapse,as N81.2.In addition,the N81.-code does not include genital prolapse complicating pregnancy(O34.5),prolapse and hernia of ovary and fallopian tube(N83.4),vaginal fornix prolapse after hysterectomy(N99.3).Conclusion To ensure accurate coding,the composite coding rules must be cross-checked with volume one.ICD-10 failed to reflect the severity of vaginal prolapse in clinical practice.To consider the severity,coding should be extended in the N81.-segment.It is essential for coders to actively acquire clinical knowledge,rein-force professional knowledge,and enhance their responsibility to improve their coding proficiency and ensure data accuracy.

Mineralocorticoid receptor(MR) overactivation plays an important role in the development and progression of diabetic kidney disease(DKD) by mediating pro-inflammatory and pro-fibrotic processes, making it a key therapeutic target for DKD. Finerenone, a third-generation, highly selective, novel nonsteroidal mineralocorticoid receptor antagonist(MRA), mitigates MR overactivation through anti-inflammatory and anti-fibrotic effects and by improving the immune-inflammatory environment. This significantly reduces cardiovascular and renal composite endpoints in patients with type 2 diabetes mellitus(T2DM) and chronic kidney disease(CKD), and improve cardiorenal outcomes. Based on its novel molecular structure, Finerenone exhibits a lower incidence of adverse effects compared to the previous MRAs. This article elucidates the molecular structure and pathophysiological role of MR, and explores the molecular mechanisms through which finerenone provides cardiorenal benefits. It also discusses the advantages and safety of finerenone compared to first- and second-generation MRAs from a molecular structure perspective, providing evidence for its clinical application.

Objective:Using the established epilepsy patient database to validate the efficacy of the web-based epilepsy diagnosis and anti-seizure medications (ASM) selection tool, EpiPick, for domestic epilepsy patients.Methods:The retrospective collection of clinical data was conducted on patients aged 10 and above who were diagnosed with epilepsy at the Comprehensive Epilepsy Center of the First Affiliated Hospital of Kunming Medical University from January 2017 to December 2020, with regular follow-up and complete information. According to the first ASM recommended by the EpiPick tool and whether they are consistent with the actual ASM used by patients, patients were divided into EpiPick group and clinical group to verify the effectiveness of the EpiPick tool in selecting ASM. The drug retention rate, Engel score, and cumulative probability of no consecutive episodes within 30 months after using the first ASM were compared between the 2 groups, and Kaplan-Meier survival curves were drawn. Finally, the diagnostic results provided by the EpiPick tool were compared with the actual types of epileptic seizures diagnosed clinically, and consistency tests were performed.Results:A total of 364 epilepsy patients were included, including 237 in the EpiPick group and 127 in the clinical group. The ASM retention rates of patients in the EpiPick group and clinical group were 67.9%(161/237) and 56.7%(72/127), respectively, with statistically significant differences (χ2=4.534, P=0.039). Grades Ⅰ, Ⅱ, Ⅲ and Ⅳ according to the Engel scores in the EpiPick group patients who took the first ASM after diagnosis accounted for 47.3%(112/237), 14.8%(35/237), 12.7%(30/237), and 25.3%(60/237), respectively, compared to the clinical group of 32.3%(41/127), 11.8%(15/127), 11.0%(14/127), and 44.9%(57/127), respectively. There was a statistically significant difference in Engel scores between the 2 groups (χ2=14.968, P=0.002). The cumulative seizure-free rates in the EpiPick group at the 1st, 6th, 12th, 30th month and above after starting the first ASM were 73.8%, 61.2%, 53.2%, and 50.6%, respectively, which in the clinical group were 52.0%, 44.1%, 40.2%, and 33.5%, respectively. The logrank test showed a statistically significant difference in the cumulative probability of consecutive seizure freedom between the 2 groups ( HR=0.644 ,95% CI 0.476-0.871 ,P<0.001). After grouping by seizure type [focal seizures (196 cases) and generalized seizures (168 cases)], the cumulative seizure-free rates at the 1st, 6th, 12th, 30th month and above after starting ASM were significantly higher in the EpiPick group than in the clinical group (comparison between the 2 groups in patients with focal seizures: HR=0.654, 95%CI 0.443-0.964, P=0.004; comparison between the 2 groups in patients with generalised seizures: HR=0.586, 95%CI 0.361-0.954, P=0.014). Among 364 patients, 293 cases were clinically diagnosed with seizure classification consistent with the classification results of EpiPick tool. Agreement between the algorithm and the experts in classifying generalized seizures was 83.9%(104/124), which in classifying focal seizures was 78.8%(189/240; Kappa=0.591, P<0.001). Conclusion:Web-based EpiPick tool is suitable to be used to select the first ASM, and is portable for Chinese non-epilepsy specialists to choose ASM for epilepsy patients.

Objective:To investigate the effect of calcification on the diagnostic accuracy of the quantitative flow fraction (CT-QFR) derived from coronary CT angiography (CCTA).Methods:A total of 244 patients (471 coronary arteries) who underwent both CCTA and invasive coronary angiography (ICA) for suspected coronary artery disease between 2019 and 2021 were included in the study. All analyses were conducted at the vessel level using CCTA and ICA images, and the morphological and hemodynamic parameters of all enrolled vessels were assessed. The group was divided into severe calcification (206 cases) and non-severe calcification (265 cases) based on whether the arc of lesion calcification was greater than 180°. Subsequently, the two groups were evaluated to the degree of coronary stenosis, the length of the target lesion, the length of calcification, the ratio of the length of calcification, the remodeling index of calcification, the quantitative flow fraction (QFR), the CT-QFR, and the distribution of the involved vessels. Pearson correlation analysis and the Bland-Altman scatterplot were used to analyze the correlation and consistency between CT-QFR and QFR values from different subgroups. The benchmark for coronary ischemia was QFR≤0.80, and the criteria for diagnosing coronary ischemia were CT-QFR≤0.80 and luminal stenosis≥50%, respectively, and the effectiveness of CT-QFR for coronary ischemia was evaluated by plotting the ROC curves in various calcification subgroups.Results:The degree of luminal stenosis, lesion length, calcification length ratio, and calcification remodeling index were substantially higher in the severely calcified group than in the non-severely calcified group (all P<0.05). The results of the Pearson correlation analysis demonstrated a significant association between CT-QFR and QFR in both the severe and non-severe calcification groups ( r=0.85, 95%CI 0.81-0.88, P<0.001; r=0.91, 95%CI 0.89-0.93, P<0.001); in contrast, the Bland-Altman analysis indicated that the CT-QFR and QFR measurements in the severely calcified group exhibited a high level of agreement, with a mean difference of -0.01 (95% limits of agreement -0.22 to 0.20) for measurements in the severely calcified group and 0 (95% limits of agreement -0.15 to 0.16). The specificity, positive predictive value, negative predictive value, and area under the curve (AUC) for the diagnosis of ischaemic lesions by CT-QFR and CCTA alone were lower in the severely calcified group than in the non-severely calcified group, but the difference in AUC between the two groups for CT-QFR was not statistically significant ( P>0.05), and the difference in AUC for the morphological assessment of CCTA was statistically significant. The diagnostic effectiveness of CCTA alone was considerably worse than the specificity and AUC of CT-QFR for the various calcified subgroups for the diagnosis of ischemic lesions (all P<0.001). Conclusions:Severe calcification somewhat affected the diagnosis of ischaemic lesions by CT-QFR, but there was still a high correlation and concordance between CT-QFR and QFR within the severely calcified group, and the diagnostic efficacy was significantly better than that assessed by CCTA morphology alone.

Objective To monitor the indoor radon concentration of urban residents in Shiyan, China, and to analyze the related influencing factors. Methods From April to July, 2019, RSKS standard detectors were used to measure the indoor radon concentration of 125 households in Shiyan, and the results were analyzed. Results The indoor radon concentration of residents in Shiyan showed a skewed distribution, ranging from 13.8 to 145 Bq/m³, and M (P₂₅,P₇₅) was 38.3 (29.0,62.0) Bq/m³. The estimated annual effective dose of radon and radon daughters from inhalation was 0.52-5.50 mSv, and M (P₂₅,P₇₅) was 1.45 (1.10, 2.36) mSv, which was consistent with literature. Building structure (H = 14.10, P < 0.001), floor (H = 24.41, P < 0.001), and geographical region (H = 8.963, P < 0.05) were influencing factors of indoor radon concentration, and the differences were significant. Conclusion The indoor radon concentration of urban residents in Shiyan is lower than the national standard limit. However, in daily life, it is still necessary to take appropriate measures to reduce the concentration of indoor radon as much as possible.
