The effect of clear aligner treatment on root resorption and soluble intercellular adhesion molecule-1 in orthodontic patients with extraction

:1122-1127
 
       目的   评估无托槽隐形矫治应用在正畸拔牙患者中的效果及对牙根吸收、可溶性细胞间黏附分子-1(sICAM-1)的影响。方法   纳入2022年1月—2024年8月的70例正畸拔牙患者,按照治疗方法分组,即对照组(35例,给予固定矫治)、观察组(35例,给予无托槽隐形矫治),评价组间牙根吸收情况、牙周指标、炎症因子、矫治时间。果   治疗结束时,两组均出现牙根吸收情况,但是观察组无牙根吸收>3 mm病例,而对照组存在牙根吸收>3 mm、>4 mm病例,P<0.05。治疗前,两组牙周指标[龈沟出血指数(SBI)、牙龈指数(GI)、菌斑指数(PLI)]、炎症因子[白介素-1β(IL-1β)、sICAM-1]比较差异无统计学意义(P>0.05)。治疗后,两组SBI、GI、PLI、IL-1β、sICAM-1升高,且观察组SBI、GI、PLI、IL-1β、sICAM-1低于对照组(P<0.05)。与对照组比较,观察组矫治时间更长(P<0.05)。结论   对正畸拔牙患者进行无托槽隐形矫治,虽然治疗时间长,但是可以抑制牙根吸收,减轻炎症反应,提高牙周健康水平。

基于 NHANES 数据库中年人群血清同型半胱氨酸水平与肾功能下降的阈值效应分析

Threshold effect of serum homocysteine level on kidney function decline among middle-aged adults in America based on NHANES database

:1061-1068
 
       目的   血清同型半胱氨酸(Hcy)水平与慢性肾脏病(CKD)的进展相关,但中年人群的非线性关联研究较少,本研究旨在寻找慢性肾脏病危险因素。方法   本研究基于NHANES 1996—2006年数据,纳入5 361例45~65岁参与者,以估算肾小球滤过率(eGFR)<60 mL/(min·1.73 m2 )和尿白蛋白/肌酐比值(uACR)≥30 mg/g评估肾功能下降。结果   通过逻辑回归及平滑曲线拟合分析发现,Hcy每升高1 µmol/L,eGFR降低的风险增加8%(OR=1.08,95%CI1.06~1.10),uACR升高的风险增加2%(OR=1.02,95%CI:1.00~1.04)。非线性分析显示,Hcy对eGFR的阈值效应拐点为13.4 µmol/L(拐点左侧OR=1.59,95%CI:1.49~1.70;右侧无显著关联)。亚组分析表明,性别、高血压、糖尿病等协变量无交互作用,然而,在敏感性分析中,糖尿病患者中Hcy与eGFR降低的关联更强(交互P=0.015 8)。结论   本研究提示,控制Hcy水平或可延缓美国中年人群(尤其是糖尿病患者)的肾功能衰退。
        Objective   Elevated serum homocysteine(Hcy)levels are linked to chronic kidney disease(CKD)progression,yet the nonlinear relationship in middle-aged populations remains underexplored.Methods  This  study analyzed data from 5 361 participants aged 45–65 years in the NHANES 1996–2006 cohort.Renal dysfunction was defined as an estimated glomerular filtration rate(eGFR)<60 mL/min/1.73 m2  and urinary albumin-to-creatinine ratio(uACR)≥30 mg/g.Results  Logistic regression and smoothed curve fitting revealed that each 1 µmol/L increase in Hcy elevated the risk of reduced eGFR by 8%(OR=1.08,95% CI:1.06–1.10)and uACR by 2%(OR=1.02,95% CI:1.00–1.04).A nonlinear threshold effect was identified at 13.4 µmol/L,with a stronger association below this threshold(OR=1.59,95% CI:1.49–1.70)and no significant effect above it.Subgroup analyses showed no interactions with gender or hypertension,but a stronger Hcy-eGFR association was observed in diabetics(interaction P=0.0158).Conclusions  These findings suggest that controlling Hcy levels may mitigate renal decline,particularly in diabetic populations,warranting further causal investigations.

运动因子对心血管系统保护作用的研究进展

The protective effects of exerkines on cardiovascular system

:870-879
 
       运动可以调节机体代谢,预防和治疗由糖脂代谢紊乱所引发的心血管疾病。运动因子是在运动过程中,由肌肉、脂肪以及肝脏等多个组织合成和分泌的一系列生物活性物质,包括蛋白质和多肽类分子、小分子代谢物以及核酸等。诸多研究证实,运动因子是运动调节机体代谢的重要因素之一,也是机体从运动中获益的关键分子机制。近年来,随着蛋白质组学、代谢组学以及高通量测序等相关技术的飞速发展,越来越多的运动因子被陆续发现和证实。这不仅拓宽了人们对机体从运动中获益相关机制的认知,还激发了人们对运动因子在健康领域应用前景的浓厚兴趣。文章系统地阐述了运动因子对机体心血管系统的影响,旨在揭示运动因子在促进心血管健康以及治疗心血管疾病等方面的积极效用。

广州中医优势病种分值付费政策实施效果探析

Analysis on the effect of dominant diseases of traditional Chinese medicine under the DIP payment mode in Guangzhou

:849-854
 
       目的   分析广州市中医优势病种按病种分值付费政策实施效果,以期为完善广州市中医病种付费方式改革提供参考思路。方法   以广州市某三甲中医医院住院患者在政策实施前(n=6 057)及实施后(n=7 208)住院病历为研究样本,对医院次均住院医疗费用、中医综合治疗费占比、平均住院日进行两独立样本非参数检验等描述性统计分析。  政策实施后,住院人次增长19%,患者次均住院医疗费用下降7.02%(P<0.001),中医综合治疗费用占比提升0.8%P>0.05),医疗机构平均住院日缩短0.63 d(P<0.001),入组中医优势病种患者自费率较非入组的低,医疗机构总体病例组合指数下降,中医优势病种结算有盈余。结论  中医优势病种按病种分值付费政策有利于医保-患者-医院三方共赢;但中医优势病种入组率有待提高,建议加大对中医医疗机构的支持与助力;中医综合治疗费用占比提升不显著,建议完善中医治疗项目医疗服务价格动态调整机制;中医优势病种仅局限在住院,建议实现诊疗单元全覆盖。
       Objective  To discuss the correlation analysis of the hospitalization expenses of TCM dominant diseases under the DIP payment mode,and provide a reference for further promoting the reform of the payment mode of TCM dominant diseases in Guangzhou.Methods  The nonparametric test was used to analyze the number of inpatients,the average hospitalization cost,and the proportion of TCM comprehensive treatment on the data of inpatient records before and after the implementation of the TCM dominant diseases policy,the sample sizes were 6 057 and 7 028 respectively.Results  After the implementation of the TCM dominant diseases policy,there was a slight fluctuation in the number of inpatients from 6 057 to 7 208,the average hospitalization cost was decreased by 7.02%(P<0.001),the proportion of TCM comprehensive treatment costs had an increase of 0.8%(P0.05),the average length of hospital stay was shorten by 0.63 days(P<0.001),the self-expense  rate of the patients with the TCM dominant diseases of in the group was lower than that of the patients without the group,the total case mix index value of the hospital decreased,but there was a surplus on the group of TCM dominant diseases settlement.Conclusios  The policy is conducive to the tripartite win-win of medical insurance,patients and hospitals.However,the enrollment rate of TCM dominant diseases need to be improved,which is suggested to increase the support for TCM hospitals.The proportion of TCM comprehensive treatment has not increased significantly,so it is suggested to improve the dynamic adjustment mechanism of medical service price of TCM treatment items.The TCM dominant diseases are only limited to hospitalization,and it is recommended to achieve full coverage of diagnosis and treatment units.
