小儿假性胰腺囊肿的诊断和治疗

目的探讨准确地诊断和治疗小儿假性胰腺囊肿.方法总结近10年来我们收治经B超、钡餐、CT和MRI以及手术证实的假性胰腺囊肿15例.结果发现15例中男11例,女4例,年龄最小1岁4个月,最大13岁,平均年龄9.4岁.而且7例有明显外伤史(7/15,占40%),恶心呕吐(14/15,占93%)、腹痛(11/15,占73%),腹部肿块(10/15,占66%)为主要临床表现,其次有发热、消瘦、贫血.此外,在诊断上除依靠病史、体检和临床表现外,B超是最适宜和有价值的诊断依据,钡餐、CT和MRI可以帮助诊断和鉴别诊断,还发现一旦血清淀粉酶下降后又重新回升,不但对确诊有重要意义,也是手术的重要指证.14例接受手术治疗患儿均恢复良好,无1例死亡.结论①小儿假性胰腺囊肿诊断除主要依靠病史、体征外,B超对小儿仍是有价值的辅助检查,诊断困难时可结合钡餐、CT和MRI加以鉴别.②小儿假性胰腺囊肿多与外伤有关,男＞女,因男孩好动、顽皮受伤机率多.③囊肿形成超过6周,或者B超显示囊肿壁形成明显时应选用内引流手术,较大囊肿仅外引流难以治愈.     

早期TEN和TPN对创伤后免疫和代谢的影响

目的 观察创伤后早期肠内和肠外营养对机体免疫和代谢功能的影响。方法 对复合务患者进行早期肠内或肠外营养支持,观察患者营养支持前后代谢和免疫指标的变化。结果 较之肠外营养,肠内组营养前后前白蛋白变化明显,淋巴细胞增殖率增加显著。而肠外营养组每日氮损失量明显小于肠内营养组。两组间免疫球蛋和Ｔ细胞亚群变化无明显差异 。结论创伤后早期肠内营养支持可促进机体免疫功能恢复,减少并发症发生率。而肠外营养更有利于     

Novel stop-gain RNF170 variation detected in a Chinese family with adolescent-onset hereditary spastic paraplegia

Hereditary spastic paraplegia (HSP) is a heterogeneous group of inherited neurodegenerative disease characterized by progressive lower limb spasticity. Recent studies revealed that biallelic variants in RNF170 gene cause autosomal recessive complicated HSP with infancy onset. Here, we report an adolescent-onset HSP patient from a consanguineous Chinese family, with lower extremity stiffness, spastic gait, and unstable straight-line walking as the main manifestations. Whole-exome sequencing identifies a novel RNF170 mutation c.190C>T (p.R64*), which co-segregates with the disease in this pedigree. Functional analysis, including quantitative real-time PCR (RT-qPCR) and Western blot, indicates that both the mRNA and protein levels of mutant RNF170 are significantly reduced, which confirms the loss-of-function mechanism. Our study expands the spectrum of RNF170-associated HSP, while the RNF170 protein-involved degradation of the inositol 1,4,5-trisphosphate receptor in neurodegenerative motor neuron disorders deserves further investigation.     

Prevalence and factors associated with late diagnosis among older adults living with HIV in liuzhou,China: 2010−2020

This paper aimed to quantify and characterize the prevalence and associated factors for late diagnosis in older adults living with human immunodeficiency virus (HIV) in Liuzhou, China, from 2010 to 2020. The characteristics of older adults living with HIV were described separately in time, space and population. Multivariate logistic regression analysis evaluates the factors influencing late diagnosis in HIV-positive adults ≥ 50 years of age. The majority of older adults living with HIV were over 60 years old, male, and with CD4 counts < 200 cells/μl at diagnosis, with most late diagnoses being more likely to report heterosexual transmission. These two factors may potentially provide a positive influence on late diagnosis: older and CD4 counts < 500 cells/μl. In contrast, females and those with homosexual or other transmission provide a negative. These results suggest that late diagnosis of HIV-positive adults ≥ 50 years of age remains a severe and growing epidemiological issue.     

妊高征患者与ACE基因缺失多态性研究

目的：探讨血管紧张素转换酶（ＡＣＥ）基因的缺失多态性与妊高征的关系。方法：对５２例妊高征患者（观察组）及１００例正常产妇,应用聚合酶链反应技术检测ＡＣＥ基因的缺失／插入多态性。结果：观察组的缺失型纯合子（ＤＤ型）ＡＣＥ基因占６５％,高于对照组的１６％;观察组的缺失型（Ｄ型）ＡＣＥ等位基因出现频率为７５％,亦高于对照组的３３％（Ｐ〈０．０１）。结论：妊高征的发病与ＡＣＥ基因的缺失多态性有关。
