Purpose: Pharmacogenetics (PGx) is an emerging aspect of personalized medicine with the potential to increase efficacy and safety of pharmacotherapy. However, PGx testing is still not routinely integrated into clinical practice. We conducted an observational case series study where PGx information from a commercially available panel test covering 30 genes was integrated into medication reviews. The aim of the study was to identify the drugs that are most frequently object of drug-gene-interactions (DGI) in the study population.

Patients and methods: In out-patient and in-patient settings, we recruited 142 patients experiencing adverse drug reaction (ADR) and/or therapy failure (TF). Collected anonymized data from the individual patient was harmonized and transferred to a structured database.

Results: The majority of the patients had a main diagnosis of a mental or behavioral disorder (ICD-10: F, 61%), of musculoskeletal system and connective tissue diseases (ICD-10: M, 21%), and of the circulatory system (ICD-10: I, 11%). The number of prescribed medicines reached a median of 7 per person, resulting in a majority of patients with polypharmacy (≥5 prescribed medicines, 65%). In total, 559 suspected DGI were identified in 142 patients. After genetic testing, an association with at least one genetic variation was confirmed for 324 suspected DGI (58%) caused by 64 different drugs and 21 different genes in 141 patients. After 6 months, PGx-based medication adjustments were recorded for 62% of the study population, whereby differences were identified in subgroups.

Conclusion: The data analysis from this study provides valuable insights for the main focus of further research in the context of PGx. The results indicate that most of the selected patients in our sample represent suitable target groups for PGx panel testing in clinical practice, notably those taking drugs for mental or behavioral disorder, circulatory diseases, immunological diseases, pain-related diseases, and patients experiencing polypharmacy.

目的:药物遗传学(PGx)是个性化医疗的一个新兴方面,具有提高药物治疗有效性和安全性的潜力。然而,PGx检测仍未常规纳入临床实践。我们进行了一项观察性病例系列研究,将来自涵盖30个基因的市售面板测试的PGx信息整合到药物评价中。该研究的目的是确定在研究人群中最常成为药物-基因相互作用(DGI)对象的药物。患者和方法:在门诊和住院环境中,我们招募了142名出现药物不良反应(ADR)和/或治疗失败(TF)的患者。从个别患者收集的匿名数据被协调并转移到结构化数据库。结果:大多数患者的主要诊断为精神或行为障碍(ICD-10: F, 61%)、肌肉骨骼系统和结缔组织疾病(ICD-10: M, 21%)和循环系统疾病(ICD-10: I, 11%)。处方药物数量中位数达到每人7种,导致大多数患者使用多种药物(处方药物≥5种,65%)。142例患者中共发现559例疑似DGI。基因检测后,141例患者中64种不同药物和21种不同基因引起的324例疑似DGI(58%)与至少一种遗传变异相关。6个月后,62%的研究人群记录了基于pgx的药物调整,从而在亚组中确定了差异。结论:本研究的数据分析为PGx背景下的进一步研究重点提供了有价值的见解。结果表明,我们样本中的大多数患者代表了临床实践中PGx面板检测的合适目标群体,特别是那些服用精神或行为障碍、循环系统疾病、免疫疾病、疼痛相关疾病的患者,以及服用多种药物的患者。

Background: Stroke has a high disability rate, and 30% of stroke cases have an unknown cause. Accurate diagnosis and treatment of stroke requires consideration of several rare heritable and non-heritable factors.

Objective: This study aimed to evaluate the impacts of three genetic polymorphisms (rs369149111 in HTRA1, rs1803628 in GAS6 and rs9808753 in IFNGR2) on stroke susceptibility among the Chinese Han population.

Methods: Three single nucleotide polymorphisms (SNPs) from 623 stroke cases and 572 healthy controls were genotyped by the Agena MassARRAY platform. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by logistic regression analysis to evaluate the associations of three SNPs with stroke susceptibility. Additionally, SNP-SNP interactions were analyzed by multifactor dimensionality reduction (MDR).

Results: As demonstrated by the overall analysis, rs9808753 in IFNGR2 (allele: OR = 1.25, 95% CI = 1.06-1.47, p = 0.007; homozygous: OR = 1.59, 95% CI = 1.14-2.23, p = 0.007; dominant: OR = 1.31, 95% CI = 1.02-1.67, p = 0.032; recessive: OR = 1.42, 95% CI = 1.05-1.91, p = 0.022; additive: OR = 1.26, 95% CI = 1.07-1.48, p = 0.007) was associated with an increased susceptibility to stroke. Besides, stratification analysis suggested that rs9808753 was associated with an increased risk of stroke in subgroup aged ≤ 64 years, males and drinkers (p < 0.05). And rs1803628 in GAS6 was significantly associated with an increased susceptibility to stroke in non-smokers (p < 0.05).

Conclusion: A risk-increasing effect of IFNGR2 rs980875 on stroke was detected in this study, which further broadens the understanding of the relationship between genetic polymorphisms and stroke susceptibility.

背景:卒中致残率高,30%的卒中病例病因不明。准确的诊断和治疗需要考虑一些罕见的遗传和非遗传因素。目的:本研究旨在评价3个遗传多态性(HTRA1基因rs369149111、GAS6基因rs1803628、IFNGR2基因rs9808753)对中国汉族人群脑卒中易感性的影响。方法:采用Agena MassARRAY平台对623例脑卒中患者和572例健康对照的3个单核苷酸多态性(snp)进行基因分型。通过logistic回归分析计算优势比(ORs)和95%置信区间(CIs),评估三个snp与卒中易感性的关系。此外,通过多因素降维(MDR)分析SNP-SNP相互作用。结果:综合分析显示,rs9808753在IFNGR2(等位基因:OR = 1.25, 95% CI = 1.06 ~ 1.47, p = 0.007;纯合子:OR = 1.59, 95% CI = 1.14-2.23, p = 0.007;显性:OR = 1.31, 95% CI = 1.02-1.67, p = 0.032;隐性:OR = 1.42, 95% CI = 1.05-1.91, p = 0.022;加性:OR = 1.26, 95% CI = 1.07-1.48, p = 0.007)与卒中易感性增加相关。此外,分层分析显示rs9808753与≤64岁亚组、男性和饮酒者卒中风险增加相关(p < 0.05)。GAS6中rs1803628与非吸烟者卒中易感性增加显著相关(p < 0.05)。结论:本研究检测到IFNGR2 rs980875对脑卒中具有增加风险的作用,进一步拓宽了对遗传多态性与脑卒中易感性关系的认识。

Proton pump inhibitors (PPIs) are commonly used medications to treat acid-related conditions, including gastro-esophageal reflux disease (GERD). Gastroenterology guidelines mention the importance of CYP2C19 in PPI metabolism and the influence of CYP2C19 genetic variations on variable responses to PPIs, but do not currently recommend the genotyping of CYP2C19 prior to prescribing PPIs. There are strong data to support the influence of CYP2C19 genetic variations on the pharmacokinetics of PPIs and clinical outcomes. Existing pharmacogenetic guideline recommendations for dose increases focus on H. pylori and erosive esophagitis indications, but PPIs are also the main therapy for treating GERD. Recent data suggest GERD patients being treated with a PPI may also benefit from genotype-guided dosing. We summarize the literature supporting this contention and highlight future directions for improved management of patients with GERD through precision medicine approaches.

质子泵抑制剂(PPIs)是治疗酸相关疾病的常用药物,包括胃食管反流病(GERD)。胃肠病学指南提到了CYP2C19在PPI代谢中的重要性,以及CYP2C19基因变异对PPI可变反应的影响,但目前不建议在开PPI处方前进行CYP2C19基因分型。有强有力的数据支持CYP2C19基因变异对PPIs药代动力学和临床结果的影响。现有的药理学指南建议增加剂量的重点是幽门螺杆菌和糜烂性食管炎适应症,但PPIs也是治疗胃食管反流的主要治疗方法。最近的数据表明,接受PPI治疗的胃食管反流患者也可能受益于基因型引导给药。我们总结了支持这一论点的文献,并强调了通过精确医学方法改善胃食管反流患者管理的未来方向。

Background: Cretinism is a subtype of congenital hypothyroidism, an endocrine disorder resulting from inadequate thyroid hormone production or receptor deficiency. Genetic abnormalities play a major role in the development of thyroid dysfunction.

Methods: We recruited 183 participants with cretinism and 119 healthy participants from the Xinjiang Uyghur Autonomous Region and randomly selected 29 tag single nucleotide polymorphisms (tSNPs) in TSHB, PAX8, TPO, NKX2-5, and TSHR in all participants. We compared genotype and allele frequencies between cases and controls utilizing the chi-squared test, logistic regression analysis, and haplotype analysis.

Results: Using the chi-squared test, a single SNP was found to be associated with cretinism (recessive model: rs3754363, OR = 0.46, 95% CI = 0.27-0.80, P = 0.00519; genotype model: P = 0.01677). We stratified neurological, myxedematous, and mixed type and determined that another SNP was associated with a higher risk when comparing myxedematous type to the neurological type (rs2277923).

Conclusion: rs3754363 has a statistically significant protective effect on people with cretinism, while rs2277923 may play a greater role in promoting the development of neurocretinism.

背景:克汀病是先天性甲状腺功能减退症的一种亚型,是一种由甲状腺激素分泌不足或受体缺乏引起的内分泌紊乱。遗传异常在甲状腺功能障碍的发展中起着重要作用。方法:从新疆维吾尔自治区招募克汀病患者183例和健康人群119例,随机选取TSHB、PAX8、TPO、NKX2-5和TSHR基因29个标签单核苷酸多态性(tsnp)。我们利用卡方检验、逻辑回归分析和单倍型分析比较了病例和对照组之间的基因型和等位基因频率。结果:卡方检验发现单个SNP与克汀病相关(隐性模型:rs3754363, OR = 0.46, 95% CI = 0.27-0.80, P = 0.00519;基因型模型:P = 0.01677)。我们将神经型、黏液性水肿型和混合型分层,并在比较黏液性水肿型和神经型时确定另一个SNP与更高的风险相关(rs2277923)。结论:rs3754363对克汀症患者有统计学意义上的保护作用,而rs2277923可能对神经克汀症的发展有更大的促进作用。

Craniofacial dysmorphism, cardiac abnormalities, ectodermal abnormalities, psychomotor delay, intellectual disability, and short stature are all hallmarks of the extremely rare disorder known as cardiofaciocutaneous syndrome (CFCS). Although CFCS is considered rare, approximately 300 cases have been documented in the literature. In this report, we discuss a patient diagnosed with CFCS without the typical heart malformations but with craniofacial features, skin abnormalities, intellectual disability, and short stature. Genetic testing revealed the presence of three potentially harmful variants: one in the MAP2K1 gene and two in the ATP2B3 and CDC42BPB genes, the significance of which is currently not yet found. Our findings in this case report suggest that the clinical symptoms of CFCS may be atypical, thereby expanding our understanding of the symptom spectrum of the disease. Simultaneously, the link between the clinical symptoms of the patient and the two unknown pathogenic variants has not been established. This case report supplements existing clinical reference material by providing valuable insights into the specific scenario.

颅面畸形、心脏异常、外胚层异常、精神运动迟缓、智力残疾和身材矮小都是一种极其罕见的疾病——心表皮综合征(CFCS)的特征。虽然氯氟烃被认为是罕见的,但文献中已经记录了大约300例。在本报告中,我们讨论了一位被诊断为CFCS的患者,没有典型的心脏畸形,但有颅面特征,皮肤异常,智力残疾和身材矮小。基因检测显示存在三种潜在的有害变异:一种在MAP2K1基因中,两种在ATP2B3和CDC42BPB基因中,其意义目前尚未发现。我们在本病例报告中的发现表明,CFCS的临床症状可能是非典型的,从而扩大了我们对该疾病症状谱的理解。同时,患者的临床症状与两种未知致病变异之间的联系尚未确定。本病例报告通过对具体情况提供有价值的见解,补充了现有的临床参考材料。

Purpose: As a rare collagen type IV hereditary kidney disease, X-linked Alport syndrome (XLAS) is the most common form of Alport syndrome, the prevalence of which is estimated at 1:10,000 of the population, four times higher than the prevalence rate of autosomal recessive Alport syndrome. To describe a series of eight XLAS children with persistent hematuria and proteinuria and the clinical outcomes after hydroxychloroquine (HCQ) treatment to assess its efficacy as early intervention.

Patients and methods: The study retrospectively analysed 8 patients with persistent hematuria and proteinuria at different onset ages who were diagnosed with XLAS and been treated with HCQ. The urinary erythrocyte count, urinary albuminn were measured. Descriptive statistics were used to estimate the patients' responses to HCQ treatment after one month, three months, and six months.

Background: High altitude pulmonary edema (HAPE) is still the most common fatal disease at high altitudes. DNA methylation proceeds with an important role in HAPE progression. This study was designed to investigate the association between CYP39A1 methylation and HAPE.

Methods: Peripheral blood samples were enrolled from 106 participants (53 HAPE patients and 53 healthy subjects) to study the association of CYP39A1 methylation with HAPE. DNA methylation site in the promoter region of CYP39A1 was detected by Sequenom MassARRAY EpiTYPER platform.

Results: Probability analysis showed that the methylation probabilities of CYP39A1_1_CpG_5 and CYP39A1_3_CpG_21 are significant differences between the cases and controls (p< 0.05). The methylation level analysis indicated that CYP39A1_1_CpG_2.3.4, CYP39A1_5_CpG_6.7, and CYP39A1_5_CpG_9.10 were higher methylation in HAPE compared to the controls (p< 0.05). CYP39A1_3_CpG_21 and CYP39A1_4_CpG_3 exhibited a lower methylation level in HAPE than that in the controls (p< 0.05). The association analysis given that CYP39A1_1_CpG_2.3.4 (OR 2.56, p= 0.035), CYP39A1_5_CpG_6.7 (OR 3.99, p= 0.003), CYP39A1_5_CpG_9.10 (OR 3.99, p= 0.003), CYP39A1_5_CpG_16.17.18 (OR 2.53, p= 0.033), and CYP39A1_5_CpG_20 (OR 3.05, p= 0.031) are associated with an increased risk of HAPE. Whereas CYP39A1_1_CpG_5 (OR 0.33, p= 0.016) and CYP39A1_3_CpG_21 (OR 0.18, p= 0.005) have a protective role in HAPE. Besides, age-stratification analysis showed that CYP39A1_1_CpG_5 (OR 0.16, p= 0.014) and CYP39A1_3_CpG_21 (OR 0.08, p= 0.023) had a protective impact on HAPE in people aged ≤32 years. CYP39A1_5_CpG_6.7 (OR 6.70, p= 0.008) and CYP39A1_5_CpG_9.10 (OR 6.70, p= 0.008) were related to an increased susceptibility to HAPE aged >32 years. Moreover, the diagnostic value of CYP39A1_3_CpG_21 (AUC = 0.712, p< 0.001) was significantly better than other CpG sites.

Conclusion: The methylation level of CYP39A1 was associated with a risk of HAPE in the Chinese population, which provided new perspective for preventing and diagnosing of HAPE.

背景:高原肺水肿(HAPE)仍然是高海拔地区最常见的致命性疾病。DNA甲基化在HAPE进展中起着重要作用。本研究旨在探讨CYP39A1甲基化与HAPE之间的关系。方法:收集106例HAPE患者(53例HAPE患者)外周血样本,研究CYP39A1甲基化与HAPE的关系。采用Sequenom MassARRAY EpiTYPER平台检测CYP39A1启动子区DNA甲基化位点。结果:概率分析显示,CYP39A1_1_CpG_5和CYP39A1_3_CpG_21的甲基化概率在病例与对照组之间差异有统计学意义(p< 0.05)。甲基化水平分析显示,CYP39A1_1_CpG_2.3.4、CYP39A1_5_CpG_6.7和CYP39A1_5_CpG_9.10在HAPE中甲基化水平高于对照组(p< 0.05)。CYP39A1_3_CpG_21和CYP39A1_4_CpG_3在HAPE中的甲基化水平低于对照组(p< 0.05)。关联分析显示,CYP39A1_1_CpG_2.3.4 (OR 2.56, p= 0.035)、CYP39A1_5_CpG_6.7 (OR 3.99, p= 0.003)、CYP39A1_5_CpG_9.10 (OR 3.99, p= 0.003)、CYP39A1_5_CpG_16.17.18 (OR 2.53, p= 0.033)、CYP39A1_5_CpG_20 (OR 3.05, p= 0.031)与HAPE风险增加相关。而CYP39A1_1_CpG_5 (OR 0.33, p= 0.016)和CYP39A1_3_CpG_21 (OR 0.18, p= 0.005)在HAPE中具有保护作用。此外,年龄分层分析显示CYP39A1_1_CpG_5 (OR 0.16, p= 0.014)和CYP39A1_3_CpG_21 (OR 0.08, p= 0.023)对≤32岁人群HAPE有保护作用。CYP39A1_5_CpG_6.7 (OR 6.70, p= 0.008)和CYP39A1_5_CpG_9.10 (OR 6.70, p= 0.008)与32岁以上HAPE易感性增加相关。CYP39A1_3_CpG_21的诊断价值(AUC = 0.712, p< 0.001)显著优于其他CpG位点。结论:CYP39A1甲基化水平与中国人群HAPE发生风险相关,为HAPE的预防和诊断提供了新的视角。

Objective: The objective of this study was to screen lymphoma radiotherapy-resistant genes using CRISPR activation (CRISPRa).

Methods: The Human CRISPRa library virus was packaged and then transfected into lymphoma cells to construct an activation library cell line, which was irradiated at the minimum lethal radiation dose to screen radiotherapy-resistant cells. Radiotherapy-resistant cell single-guide RNA (sgRNA) was first amplified by quantitative polymerase chain reaction (qPCR) in the coding region and then subject to next-generation sequencing (NGS) and bioinformatics analysis to screen radiotherapy-resistant genes. Certain radiotherapy-resistant genes were then selected to construct activated cell lines transfected with a single gene so as to further verify the relationship between gene expression and radiotherapy resistance.

Results: A total of 16 radiotherapy-resistant genes, namely, C20orf203, MTFR1, TAF1L, MYADM, NIPSNAP1, ZUP1, RASL11A, PSMB2, PSMA6, OR8H3, TMSB4Y, CD300LF, EEF1A1, ATP6AP1L, TRAF3IP2, and SNRNP35, were screened based on the NGS results and bioinformatics analysis of the radiotherapy-resistant cells. Activated cell lines transfected with a single gene were constructed using 10 radiotherapy-resistant genes. The qPCR findings showed that, when compared with the control group, the experimental group had significantly up-regulated mRNA expression of MTFR1, NIPSNAP1, ZUP1, PSMB2, PSMA6, EEF1A1, TMSB4Y and TAF1L (p < 0.05). No significant difference in the mRNA expression of AKT3 or TRAF3IP2 (p > 0.05) was found between the two groups (p > 0.05).

Conclusion: The 16 genes screened are potential lymphoma radiotherapy-resistant genes. It was initially determined that the high expression of 8 genes was associated with lymphoma radiotherapy resistance, and these genes could serve as the potential biomarkers for predicting lymphoma radiotherapy resistance or as new targets for therapy.

目的:本研究的目的是利用CRISPR激活(CRISPRa)筛选淋巴瘤放疗耐药基因。方法:将人CRISPRa文库病毒包装后转染淋巴瘤细胞,构建激活文库细胞系,以最小致死辐射剂量照射,筛选放疗耐药细胞。首先通过定量聚合酶链反应(qPCR)在编码区扩增出放疗耐药细胞单导RNA (sgRNA),然后通过下一代测序(NGS)和生物信息学分析筛选放疗耐药基因。然后选择某些放疗耐药基因,构建单基因转染的活化细胞系,进一步验证基因表达与放疗耐药之间的关系。结果:基于NGS结果及对放疗耐药细胞的生物信息学分析,共筛选到C20orf203、MTFR1、TAF1L、MYADM、NIPSNAP1、ZUP1、RASL11A、PSMB2、PSMA6、OR8H3、TMSB4Y、CD300LF、EEF1A1、ATP6AP1L、TRAF3IP2、SNRNP35等16个放疗耐药基因。用10个耐放疗基因构建了单基因转染的活化细胞系。qPCR结果显示,与对照组相比,实验组MTFR1、NIPSNAP1、ZUP1、PSMB2、PSMA6、EEF1A1、TMSB4Y和TAF1L mRNA表达量显著上调(p < 0.05)。两组间AKT3、TRAF3IP2 mRNA表达量差异无统计学意义(p > 0.05)。结论:筛选到的16个基因均为潜在的淋巴瘤放疗耐药基因。初步确定8个基因的高表达与淋巴瘤放疗耐药相关,这些基因可作为预测淋巴瘤放疗耐药的潜在生物标志物或作为新的治疗靶点。

Bitter taste receptors (T2Rs) consist of 25 functional receptors that can be found in various types of cells throughout the human body with responses ranging from detecting bitter taste to suppressing pathogen-induced inflammation upon activation. Numerous studies have observed clinical associations with genetic or phenotypic variants in bitter taste receptors, most notably that of the receptor isoform T2R38. With genetic variants playing a role in the response of the body to bacterial quorum-sensing molecules, bacterial metabolites, medicinal agonists and nutrients, we examine how T2R polymorphisms, expression levels and bitter taste perception can lead to varying clinical associations. From these genetic and phenotypic differences, healthcare management can potentially be individualized through appropriately administering drugs with bitter masking to increase compliance; optimizing nutritional strategies and diets; avoiding the use of T2R agonists if this pathway is already activated from bacterial infections; adjusting drug regimens based on differing prognoses; or adjusting drug regimens based on T2R expression levels in the target cell type and bodily region.

苦味受体(T2Rs)由25个功能性受体组成,可以在人体各种类型的细胞中发现,其反应范围从检测苦味到抑制病原体诱导的炎症激活。许多研究已经观察到苦味受体与遗传或表型变异的临床关联,最明显的是受体异构体T2R38。由于遗传变异在机体对细菌群体感应分子、细菌代谢物、药物激动剂和营养物质的反应中发挥作用,我们研究了T2R多态性、表达水平和苦味感知如何导致不同的临床关联。从这些遗传和表型差异来看,医疗保健管理可以通过适当使用苦味掩蔽药物来提高依从性,从而潜在地个性化;优化营养策略和饮食;如果该途径已因细菌感染而激活,则避免使用T2R激动剂;根据不同的预后调整药物方案;或根据靶细胞类型和身体部位的T2R表达水平调整药物方案。

Purpose: Nonunion of fractures occurs in about 15% of all fractures causing repeated surgical interference and prolonged morbidity. We performed this systematic review to assess genes and polymorphisms influencing fractures' nonunion (FNU).

Methods: We searched between 2000 and July 2022 in PubMed, EMBASE, the Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews, Genome Wide Association Studies (GWAS) Catalog, and the Science Citation Index, with the keywords nonunion of fractures, genetic influence, and GWAS. The exclusion criteria were review articles and correspondence. The data were retrieved to determine the number of studies, genes, and polymorphisms and the total number of subjects screened.

Results: A total of 79 studies were reported on nonunion of fractures and genetic influence. After the inclusion and exclusion criteria, ten studies with 4402 patients' data were analyzed. Nine studies were case-controlled, and 1 GWAS. It was identified that patients with polymorphisms in the genes ANXA3, BMP2, CALY, CYR61, FGFR1, IL1β, NOG, NOS2, PDGF gene, and TACR1 are prone to develop a nonunion of fractures.

Conclusion: We believe that for patients who develop an early nonunion of fractures, a genetic study should be conducted for single nucleotide polymorphism (SNP) and genes so that alternative and more aggressive treatment can be performed to heal fractures without prolonged morbidity.

目的:骨折不愈合约占所有骨折的15%,导致反复手术干预和长期发病。我们进行了这项系统综述,以评估影响骨折不愈合(FNU)的基因和多态性。方法:检索2000年至2022年7月PubMed、EMBASE、Cochrane中央对照试验注册库和Cochrane系统评价数据库、全基因组关联研究(GWAS)目录和科学引文索引,检索关键词为骨折不愈合、遗传影响和GWAS。排除标准为综述文章和通信。检索数据以确定研究、基因和多态性的数量以及筛选的受试者总数。结果:共报道了79项关于骨折不愈合及其遗传影响的研究。根据纳入和排除标准,对10项研究4402例患者数据进行分析。9项研究为病例对照,1项为GWAS。研究发现,具有ANXA3、BMP2、CALY、CYR61、FGFR1、IL1β、NOG、NOS2、PDGF基因和TACR1基因多态性的患者易发生骨折不愈合。结论:我们认为,对于发生骨折早期不愈合的患者,应该进行单核苷酸多态性(SNP)和基因的遗传学研究,以便进行替代和更积极的治疗来治愈骨折,而不会延长发病率。
