Objective:To evaluate the efficacy and safety of febuxostat in the treatment of hyperuricemia with hypertension.Methods:Randomized controlled trials (RCT) on the treatment of hyperuricemia with hypertension using febuxostat were retrieved from Medline, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), Wanfang Database, and VIP Database from January 2013 to July 2023, according to the retrieval strategy. Two trained researchers completed the literature screening, quality evaluation, and data extraction. Meta-analysis was performed using RevMan 5.3. The fixed-effect model or random-effects model was used to analyze the research data, and subgroup analysis was conducted to identify the source of heterogeneity.Results:A total of 5 RCTs involving 456 patients (228 in the experimental group and 228 in the control group) were included in the meta-analysis, all of which were English-language literatures and foreign studies. In the treatment of hyperuricemia with hypertension, febuxostat showed a statistically significant difference in reducing serum uric acid (sUA) levels compared to control drugs [MD(95% CI)=-1.31(-2.55, -0.07), P=0.040]; there was no statistically significant difference in reducing systolic blood pressure (SBP) [SMD(95% CI)=-0.12(-0.51, 0.27), P=0.540] or diastolic blood pressure (DBP) [SMD(95% CI)=-0.15(-0.40, 0.09), P=0.220]. Subgroup analysis showed that the difference in intervention drugs in the control group may be the cause of heterogeneity in sUA levels, and the difference in intervention time may be the cause of heterogeneity in SBP levels among different studies. There was no statistically significant difference in the incidence of adverse reactions between the febuxostat group and the control group [RD (95% CI) =-0.01(-0.08, 0.06), P=0.770]. Conclusion:Febuxostat has a significant advantage in improving sUA levels and is relatively safe in the treatment of hyperuricemia with hypertension, but it does not show significant advantages in blood pressure control.

This new teaching method was used to train base-force soldiers' rescue skills, and its effect was compared with that of traditional teaching method. The data was analyzed by SPSS 19.0.Results:Trainees who received this new method of training were faster to use tourniquets than those who received traditional method.Conclusion:Applying the BOPPPS model and the conditioned reflex principle which reflected from unconscious incompetence to unconscious competence in the teaching of tourniquets can effectively improve trainees' skills, gaining better results in teaching.

Objective:To analyze the level of self-management and its influencing factors in patients with systemic lupus erythematosus (SLE).Methods:A cross-sectional study. From January to December 2021, patients with SLE in the Department of Rheumatology and Immunology in the First Affiliated Hospital of Henan University of Traditional Chinese Medicine were selected as the study objects by convenience sampling method. A total of 135 questionnaires were distributed in this study, 135 were recovered, and 128 were valid. The general data of the patients were collected, and the self-management level, self-efficacy, family care and meaning in life of the patients were evaluated with the chronic disease self-management behavior scale, general self-efficacy scale (GSES), family adaption partnership growth affection resolve index (APGAR) and the meaning in life questionnaire (MLQ). Multiple linear regression analysis was applied to explore the factors affecting the self-management of SLE patients.Results:The total score of chronic disease self-management behavior scale in the 128 SLE patients was (28.77±6.58) points. Pearson correlation analysis showed strong correlation between self-efficacy, sense of life meaning and self-management ( r=0.748, 0.717, both P<0.001), there was a moderate correlation between family care and self-management ( r=0.560, P<0.001). Multiple linear regression analysis showed that educational level ( β′=0.457), disease activity ( β′=-0.211), self-efficacy ( β′=-0.372), family care ( β′=-0.510), meaning in life ( β′=-0.386) were influencing factors of self-management level in patients with SLE (all P<0.05). Conclusions:The self-management level of SLE patients needs to be improved. Disease activity, self-efficacy, meaning in life and other factors can affect the patients′ self-management level.

ObjectiveTo study the clinical efficacy of the Qingre Lishi Huazhuo method on patients with chronic gouty arthritis of dampness-heat obstruction syndrome and the effect on nucleotide-binding oligomerization domain-like receptor 3（NLRP3）/interleukin-1β （IL-1β） signaling pathway to preliminarily explore its mechanism. MethodSixty patients with chronic gouty arthritis of dampness-heat obstruction syndrome were enrolled and divided into a treatment group （30 cases） and a control group （30 cases） according to the random number table method. Thirty people were assigned to the healthy group. Patients in the control group were treated with oral Febuxostat， while those in the treatment group were treated with modified Simiaosan combined with Febuxostat. Treatment lasted four weeks. The general clinical data， traditional Chinese medicine （TCM） syndrome scores， serum uric acid （UA）， serum creatinine （SCr）， blood urea nitrogen （BUN）， fasting blood glucose （FPG）， low-density lipoprotein （LDL）， triglyceride （TG）， total cholesterol （TC）， erythrocyte sedimentation rate （ESR）， and C-reactive protein （CRP） of patients were recorded. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of IL-1β，TNF-α， and IL-6，and the levels of NLRP3，cysteinyl aspartate-specific protease-1 （Caspase-1）， and apoptosis-associated speck-like protein containing a CARD （ASC） were detected by Western blot. ResultBefore treatment， the levels of body mass index （BMI）， systolic blood pressure （SBP），diastolic blood pressure （DBP），UA，SCr，BUN，FPG，LDL，TG，and TC in both groups significantly increased （P<0.05，P<0.01），and the levels of HDL significantly decreased as compared with those in the healthy group（P<0.05）. Additionally， the levels of IL-1β， TNF-α， and IL-6 in both groups significantly increased before treatment （P<0.01）. Compared with the results before treatment， patients in the two groups had significant reductions in tube pain， joint tenderness， joint swelling，joint fever， activity disorders， body fatigue， sliminess， bitter mouth， yellow and red urine， and tongue manifestation scores （P<0.05，P<0.01）. Compared with patients in the control group after treatment， those in the treatment group had a significant decrease in joint fever， body fatigue， sliminess， bitter mouth，sticky stool，yellow and red urine， tongue manifestation score， and pulse score （P<0.05）. The total effective rate in the treatment group was 80.0% （24/30）， higher than 56.7% （17/30）in the control group（χ²=11.916，P<0.05）. Compared with the results before treatment， BMI， SBP， DBP， UA， SCr， BUN， FPG， LDL， TG， TC， ESR，CRP， IL-1β， TNF-α， IL-6 levels， and VAS score in both groups significantly decreased （P<0.05，P<0.01）. Compared with patients in the control group after treatment， those in the treatment group had decreased DBP，ESR， IL-1β levels， and VAS score （P<0.05）. Western blot results showed that before treatment， the protein expression of NLRP3， Caspase-1， and ASC in peripheral blood mononuclear cells （PBMCs） of patients in both groups were higher than those in the healthy group （P<0.01）. Compared with the results before treatment， the protein expression of NLRP3， Caspase-1， and ASC in PBMCs in patients of both groups after treatment decreased （P<0.05，P<0.01）. Compared with the control group after treatment， the treatment group showed decreased expression levels of NLRP3 and Caspase-1（P<0.05）. ConclusionThe Qingre Lishi Huazhuo method can effectively improve the clinical symptoms and reduce inflammation of chronic gouty arthritis of dampness-heat obstruction syndrome with good safety. The mechanism may be related to the inhibition of the NLRP3/IL-1β signaling pathway.

ObjectiveTo investigate the effect of modified Simiaosan on miR-223-3p and NOD-like receptor thermal protein domain associated protein 3 （NLRP3）/interleukin-1β （IL-1β） signaling pathway in rat model with acute gouty arthritis （AGA） and explore the anti-inflammatory mechanism of modified Simiaosan on AGA. MethodA total of 72 8-week-old male SD rats were selected. They were divided into blank group， model group， colchicine group （0.3 mg·kg^-1）， high-dose modified Simiaosan group （31.75 g·kg^-1）， medium-dose modified Simiaosan group （15.75 g·kg^-1）， and low-dose modified Simiaosan group （7.875 g·kg^-1） according to random number table method， with 12 rats in each group. Except for the blank group， monosodium urate （MSU） crystal suspension was injected into the right ankle joint of rats by the Coderre method in other groups to replicate the rat model with AGA. The drug administration groups were given the corresponding drug solution by gavage， and the model group and the blank group were given an equal volume of sterile sodium chloride solution by gavage for one week. The circumference of the rats' ankle joint was measured， and the swelling degree of the ankle joint was calculated. Hematoxylin-eosin （HE） staining was used to detect the pathological morphological changes in the synovial tissue of the ankle joint. The levels of IL-1β， tumor necrosis factor-α （TNF-α）， and interleukin-6 （IL-6） in the serum of rats in each group were detected by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the protein expressions of NLRP3， Caspase-1， and apoptosis-related spot-like protein （ASC） in synovial tissue of rats in each group， and real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expressions of NLRP3， Caspase-1， and ASC and the expression of miR-223-3p in synovial tissue of rats. ResultCompared with that in the normal group， the swelling degree of the ankle joint in the model group was higher （P<0.01）， and the synovial tissue structure was disordered. Synovial cells proliferated obviously， and a large number of inflammatory cells were infiltrated. The levels of IL-1β， IL-6， and TNF-α in the serum of the model group increased significantly （P<0.01）， and the protein and mRNA expressions of NLRP3， Caspase-1， and ASC increased， while expression of miR-223-3 decreased. Compared with the model group， the swelling degree of ankle joint in the colchicine group and high-dose and medium-dose modified Simiaosan groups was lower （P<0.05）. Synovial cell proliferation and inflammatory cell infiltration of the colchicine group and high-dose， medium-dose， and low-dose modified Simiaosan groups were reduced to varying degrees， among which the colchicine group and high-dose modified Simiaosan group improved most obviously. The levels of IL-1β， IL-6， and TNF-α in the serum of rats in different dose groups of modified Simiaosan and colchicine group decreased significantly （P<0.01）， while the protein and mRNA expressions of NLRP3， Caspase-1， and ASC increased （P<0.01）. The expression of miR-223-3p in synovial tissue of the medium-dose and high-dose modified Simiaosan groups and colchicine group increased significantly （P<0.01）. Compared with those in the colchicine group， the levels of IL-1β， IL-6， and TNF-α in the low-dose modified Simiaosan group increased greatly （P<0.01）. In the medium-dose modified Simiaosan group， the protein expressions of NLRP3， Caspase-1， and ASC increased， and the expression of miR-223-3p decreased （P<0.05）. In the low-dose modified Simiaosan group， the levels of IL-1β， IL-6， and TNF-α increased greatly （P<0.01）， as well as the protein and mRNA expressions of NLRP3， Caspase-1， and ASC， while the expression of miR-223-3p was decreased （P<0.01）. ConclusionModified Simiaosan may play an anti-inflammatory role by intervening in the NLRP3/IL-1β signaling pathway via regulating miR-223-3p.

Objective To study the irradiation dose of organs at risk (OAR) in involved field radiation and extended field radiation in patients with thoracic esophageal cancer who received intensity modulated radiotherapy (IMRT). Methods A total of 40 patients with thoracic esophageal cancer were treated with IMRT. The involved field, extended field, and OAR were outlined to generate IMRT plans. The conformity index (CI) and homogeneity index (HI) of planning target volume (PTV) and the irradiation parameters of OAR were evaluated for the two plans. Paired t-test was used for comparison of irradiation parameters. Results The PTV of both plans received the prescribed dose. There were no significant differences in CI and HI of PTV between the two groups (P = 0.317, 0.130). There were significant differences in average lung dose, lung V₅, lung V₂₀, lung V₃₀, spinal cord D_mean, heart D_mean, heart D_max, heart V₃₀, heart V₄₀, and heart V₆₀ between the two groups (P < 0.01). Conclusion Compared with the extended field, the involved field can reduce the irradiation dose of ORA in patients with thoracic esophageal cancer, thus reducing the risk of radiation.

Objective: To explore the effects of ApoE epsilon4 (ApoE-ε4) alleles on cognitive function and resting-state functional MRI (rs-fMRI) in patients with amnestic mild cognitive impairment(aMCI) based on a prospective cohort study. Methods: An average of 20 months of prospective observations were conducted on 16 ApoE-ε4-carriers and 24 non-carriers of aMCI. Neuropsychological assessments and rs-fMRI data were collected at both baseline and follow-up. All participants were assessed by a battery of neuropsychological tests and underwent rs-fMRI. Two core regions of the default mode network (DMN), the left posterior cingulate cortex (PCC) and the medial prefrontal cortex (mPFC), were selected as seeds to calculate the functional connectivity. Two-way repeated measures analysis of variance was used to assess the effects of ApoE genotype(ε4-carriers, nonε4-carriers), interval and the interaction between these two factors for functional connectivity extracted from changed region found by t-test.Conversion rates of dementia were compared between ApoE-ε4-carriers and nonε4-carriers at follow-up using Chi-square test. For the comparison of functional connectivity and clinical data between ApoE-ε4-carriers and nonsε4-carriers in baseline and follow-up, the normal distribution test was carried out first. If the normal distribution was fitted, the two-sample t test was used, otherwise, the Mann-Whitney rank sum test was used. Finally, the general linear model was used to assess the relationships between alterations in functional connectivity and in neuropsychological assessments as well as the interaction effect. Results: (1)Significant decline in memory domains were found in ApoE-ε4-carriers as compared to non-carriers at both baseline and follow-up. The ApoE-ε4-carriers (14/16) presented a higher conversation rate than non-carriers(13/24, χ²=4.862, P=0.027) at follow-up. (2)Functional imaging analysis revealed that ApoE-ε4-carriers exhibited significantly higher functional connectivity between the left PCC and the left angular (ApoE-ε4-carriers: 0.23±0.11, non-carriers: -0.03±0.13, t=4.800, cluster size: 1 944 mm³, P=0.004), and between the left mPFC and the left angular (ApoE-ε4-carriers: 0.33±0.21, non-carriers: 0.08±0.18, t=5.040, cluster size:1 836 mm³, P=0.006) as compared to non-carriers at follow-up. We detected significant effect for the interaction interval by ApoE-ε4 on functional connectivity between the left angular and the left PCC (F=10.833, P=0.002)as well as the left mPFC (F=7.280, P=0.010). (3)The alteration of functional connectivity value between the left mPFC and the left angular in ApoE-ε4-carriers was positively correlated with the changes ofimmediate memory (r=0.692, P=0.018). The correlation was not statistically significant in ApoE-ε4-noncarriers (r=-0.198, P=0.417) and the integration effect was significant (F=8.632, P=0.006). Conclusions The ApoE-ε4 actually accelerates the deterioration of cognitive function in aMCI patients and carriers presented relatively reserved functional connectivity between the left angular and other core regions within DMN, which indicated the disruption of functional connectivity may be one of the underline mechanisms of ApoE-ε4 during AD process.
