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 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.

AIM: To evaluate the clinical effect of toric implantable collamer lens(TICL)V4c for correcting moderate to high myopia with high astigmatism using vector analysis and quality of life impact of refractive correction(QIRC).METHODS: Retrospective case series. A total of 55 patients(90 eyes)with moderate to high myopia and high astigmatism who received TICL V4c implantation in the refraction surgery center of ophthalmology department in our hospital from January 2019 to December 2022 were collected. Followed-up for 1 a, the uncorrected distance visual acuity(UDVA), best corrected visual acuity(BCVA)and diopters were observed. Alpins vector analysis was used to evaluate the effect of astigmatism correction, and QIRC scale was used to evaluate patients' quality of life.RESULTS: At 1 a postoperatively, the UDVA of 98% eyes was the same or better than pre-operative BCVA, the safety index was 1.11±0.14, and the efficacy index was 1.11±0.15. The angle of error of 97% of the astigmatic eyes was within ±15°. The results of vector analysis showed that correction index was 0.83±0.13, angle of error was 1.00±4.49°, and index of success was 0.21±0.15. The total higher order aberrations under a pupil diameter of 6 mm was significantly increased compared with preoperatively(P<0.05), the QIRC score was significantly better than that before surgery(P<0.001), and the increase of total QIRC scores was positively correlated with preoperative spherical equivalent(rs=0.215, P<0.05), indicating that the higher degree of myopia before surgery the patients, the better the quality of life after TICL implantation.CONCLUSION: TICL V4c implantation for the correction of moderate to high myopia with high astigmatism is safe and effective, and the patients' quality of life significantly improved after surgery.

Aim To explore the correlation between residual lipoprotein cholesterol(RLP-C)and the occurrence and severity of peripheral arterial disease(PAD)in patients with type 2 diabetes mellitus(T2DM).Meth-ods 392 T2DM patients with complete data who attended the Department of Endocrinology and the Department of Cardio-vascular Medicine of People's Hospital of Henan University of Traditional Chinese Medicine from May 2022 to December 2022 were selected and classified into PAD group(n=203)and non-PAD group(n=189).General clinical data were collected between the groups,the difference of RLP-C level was compared between the two groups,the correlation between RLP-C and PAD was examined by using univariate and multivariate Logistic regression analysis,and ROC curve was plotted to analyze the predictive value of RLP-C for PAD.Results Compared with non-PAD group,RLP-C level was significantly higher in PAD group(P＜0.001);RLP-C was positively correlated with the severity of PAD(r=0.443,P＜0.001);Multifactorial Logistic regression analysis revealed that RLP-C was a major risk factor for the development of PAD in T2DM(P＜0.001);The area under the curve(AUC)of RLP-C level prediction for T2DM combined with PAD was 0.860(95％CI:0.824～0.896,P＜0.001);The optimal RLP-C threshold for predicting the development of PAD was 0.67 mmol/L.Conclusion RLP-C level was positively associated with the occurrence and severity of PAD in patients with T2DM,and RLP-C was an independent risk factor for the development of PAD.In addition,RLP-C＞0.67 mmol/L increased the risk of PAD in T2DM patients.

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: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 understand the basic characteristics of previously reported patients with hepatitis C and analyze the related factors affecting their antiviral treatment. Methods: A convenient sampling method was adopted. Patients who had been previously diagnosed with hepatitis C in the Wenshan Prefecture of Yunnan Province and Xuzhou City of Jiangsu Province were contacted by telephone for an interview study. The Andersen health service utilization behavior model and related literature were used to design the research framework for antiviral treatment in previously reported hepatitis C patients. A step-by-step multivariate regression analysis was used in previously reported hepatitis C patients treated with antiviral therapy. Results: A total of 483 hepatitis C patients, aged 51.73 ± 12.06 years, were investigated. The proportion of male, agricultural occupants who were registered permanent residents, farmers and migrant workers was 65.24%, 67.49%, and 58.18%, respectively. Han ethnicity (70.81%), married (77.02%), and junior high school and below educational level (82.61%) were the main ones. Multivariate logistic regression analysis results showed that married patients with hepatitis C (OR = 3.19, 95% CI: 1.93-5.25, compared with unmarried, divorced, and widowed patients) with high school education or above (OR = 2.54, 95% CI: 1.54-4.20, compared with patients with junior high school education or below) were more likely to receive antiviral treatment in the predisposition module. Patients with severe self-perceived hepatitis C in the need factor module (compared with patients with mild self-perceived disease, OR = 3.36, 95% CI: 2.09-5.40) were more likely to receive treatment. In the competency module, the family's per capita monthly income was more than 1,000 yuan (compared with patients with per capita monthly income below 1,000 yuan, OR = 1.59, 95% CI: 1.02-2.47), and the patients had a high level of awareness of hepatitis C knowledge (compared with patients with a low level of knowledge, OR = 1.54, 95% CI: 1.01-2.35), and the family members who knew the patient's infection status (compared with patients with an unknown infection status, OR = 4.59, 95% CI: 2.24-9.39) were more likely to receive antiviral treatment. Conclusion: Different income, educational, and marital statuses are related to antiviral treatment behavior in hepatitis C patients. Family support of hepatitis C patients receiving hepatitis C-related knowledge and their families knowing the infection status is more important in promoting the antiviral treatment of patients, suggesting that in the future, we should further strengthen the hepatitis C knowledge of hepatitis C patients, especially the family support of hepatitis C patients' families in treatment.

Objective:To evaluate the clinical efficacy of Jiawei Zhixiao Decoction and western medicine comprehensive therapy in acute attack of bronchial asthma of heat asthma syndrome.Methods:Randomized controlled trial. A total of 80 patients with acute exacerbation of bronchial asthma and TCM pattern heat asthma, who treated in the respiratory department of our hospital from January 2021 to December 2021, were selected. Accordlty to random number table method the patients were divided into the treatment group and control group, with 40 in each group. The patients in the control group were given comprehensive treatment of Western Medicine (bronchodilator and glucocorticoid, etc.). On the basis of comprehensive treatment of Western medicine, the treatment group was combined with Jiawei Zhixiao Decoction. All patients received a 14-day treatment. Before and after treatment, the TCM symptom scores were recorded, FEV1 and forced expiratory volume in one second to forced vital capacity ratio (FEV1/FVC) were measured by pulmonary function meter, and peak expiratory flow (PEF) was measured by peak expiratory flow meter. Serum TNF-α and IL-8 levels were detected by ELISA, and procalcitonin (PCT) was detected by electrochemiluminescence. The disease grade, clinical efficacy and adverse reactions were also recorded.Results:The total effective rate was 95.0% (38/40) in the treatment group and 80.0% (32/40) in the control group, the difference between the two groups was statistically significant ( χ2=4.11, P=0.043). After treatment, the TCM symptom score of the treatment group was significantly lower than that of the control group ( t=7.91, P<0.01). FEV1 [(2.83±0.37) L vs. (2.38±0.32) L, t=6.77], FEV1/FVC [(85.37±9.36) % vs. (75.50±10.24) %, t=4.50], PEF [(4.84±0.82) L vs. (3.92±0.43) L, t=6.28] was significantly higher than that of control group ( P<0.01). Serum IL-8 [(80.59±10.28) ng/L vs. (87.15±8.25) ng/L, t=3.15], TNF-α [(43.18±4.08) ng/L vs. (51.78±7.58) ng/L, t=6.32], PCT [(0.84±0.35) μg/L vs. (0.41±0.12) μg/L, t=7.35] were significantly lower than those in control group ( P<0.01). The improvement of asthma grade was significantly better than that of control group ( Z=17.86, P<0.05). During the observation period, there were no serious adverse reactions in both groups, and the safety was high. Conclusion:Application of Jiawei Zhixiao Decoction and western medicine comprehensive therapy in acute attack of bronchial asthma of heat asthma syndrome can effectively improve the TCM symptoms and lung function, attenuate the inflammation response, and alleviate the severity of asthma.

OBJECTIVE: To clarify the anti-depressive potential mechanisms of Kaixin Powder (KP), a drug that helps to prevent and treat depression and other mentaldiseases, from genome-wide transcriptome profiling. METHODS: Transcriptome and KEGG pathway analysis were conducted on the hippocampus of depressed rats, then the differentially expressed genes were validated and serum concentration of lipid parameters were identified by enzymatic assays. Furthermore, high-fat diets induced depression-like behaviors in Syrian golden hamsters were conducted to verify the predicted molecular mechanisms acquired from the transcriptome analysis. RESULTS: Transcriptome results revealed that the 24 differentially expressed genes (DEGs) in chronic mild stress (CMS) rats could be reversed after two weeks of KP treatment. The mechanisms of KP in treating depression firstly involved the regulation of several pathology modules, including lipid metabolism, synapse function and inflammation. KP could regulate imbalances of lipid homeostasis in high-fat diet induced depressive symptoms. Furthermore, it was validated that cholesterol metabolism dysfunction can be ameliorated by KP, which was correlated with upregulation of the AdipoR1-BDNF (brain-derived neurotrophic factor) co-regulatory pathway. CONCLUSION Taken together, our results demonstrated that KP not only alleviates depression via traditional mental illness targets, but it may also simulates the cholesterol metabolism and adiponectin signaling with multi-target characteristics.

【Objective】 To study the yielding rate and distribution of unexpected antibodies in blood transfusion children with thalassemia in Yunnan province, and to explore the blood transfusion strategies. 【Methods】 From January 2016 to December 2021, 298 children with thalassemia, who received blood transfusion treatment in Kunming, Xishuangbanna, Wenshan, Dehong, Yuxi and Baoshan hospitals across Yunnan Province, were selected. The unexpected antibodies of blood plasma were screened by microcolumn gel card. The samples with positive antibodies were identified for alloantibody specificity. 【Results】 Unexpected antibodies were yielded in 67 out of 298(22.48%) transfused children with thalassemia. The positive rates of unexpected antibodies in boys and girls were 16.55%(24/145) and 28.10%(43/153), respectively. The positive rates of unexpected antibodies in Han, Dai, Zhuang, Yi, Bulang, Jinuo and Miao people were 14.06%(18/128), 30.80%(32/104), 35.71%(10/28), 36.36%(8/22), 50.00%(4/8), 60.00%(3/5)and 66.67%(2/3), respectively, with statistically significant differences between each other. The positive rate of unexpected antibodies in ethnic minorities was higher than that in Han. The positive rates of unexpected antibodies in children who received the first transfusion at birth-one year old, 1~3 years old, 3~6 years old and above 6 years old were 12.50%(3/24), 10.14%(7/69), 24.54%(40/163)and 40.48%(17/42), respectively. The positive rates of unexpected antibodies in children with first transfusion after 3 years old were significantly higher than those before 3 years old. The positive rates of unexpected antibodies in children with one transfusion, 1~3, 3~10, 10~20 and more than 20 transfusions were 4.76%(1/21), 12.07%(7/58), 23.71%(23/97), 28.16%(29/103)and 36.84%(7/19), respectively, with statistically significant differences between each other. The number of blood transfusions was positively correlated with the unexpected antibody yielding. The yielding rate of unexpected antibodies in children with α thalassemia, βthalassemia, δ+ βthalassemia and untyped thalassemia was 7.50%(3/40), 17.62%(34/193), 53.70%(29/54)and 9.09%(1/11), respectively(P<0.05). The yielding rate of unexpected antibodies in transfused children with δ+ βthalassemia was the highest. And 57 unexpected antibodies of Rh blood group system were yielded, 6 anti-M antibodies, 2 anti-N antibodies and 2 undetermined. 【Conclusion】 The positive rate of unexpected antibodies in transfused children with thalassemia in Yunnan province is high. Routine antibody screening should be carried out for transfusion children with thalassemia, and blood units, compatible with ABO, Rh and MNS typing results, should be selected to ensure the safety and effectiveness of clinical blood use.
