中国藓类植物一新记录种——芒果树生藓

报道产自贵州省的中国藓类植物一新记录种———芒果树生藓( Erpodium mangiferae)。树生藓科( Erp-odiaceae)隶属于变齿藓目( Isobryales)木灵藓亚目( Orthotrichinales),该科全世界共有5属24种,主要分布在热带地区。中国报道有3属4种。该科的树生藓属( Erpodium),在我国曾经有过2种的记录,被认为是细鳞藓[Solmsiella biseriata (Austin) Steere.]和钟帽藓[Venturiella sinensis (Vent.) C. Müll.]的异名。2004年熊源新等人在贵州省罗甸县红水河谷采到1号树生藓科标本,最终鉴定为芒果树生藓( E. mangiferae C. Muell.)。此次发现也为树生藓属在中国的新分布记录。至此,我国的树生藓科共有4属5种。该文根据对标本的显微观察提供了详细的形态描述和各部分细节线条图,并对该种的分布状况进行了简要的讨论。根据资料,该种主要分布于印度南部、中部、北部和东北部,该种的发现地“贵州罗甸县红水河谷”从经纬度上看,与此前报道的最北分布地印度阿萨姆邦基本在同一纬度上,仅在经度上相差约10°,距离上相差约1400 km。该种与Erpodium glaziovii的外形相似,但根据雌苞叶与营养叶的尺寸比较,以及叶片细胞中是否存在原始小囊( primordial utri-cle)等可将两者区分开。

Ceramide Analysis in Combination With Genetic Testing May Provide a Precise Diagnosis for Self-Healing Collodion Babies

Self-healing collodion baby (SHCB), also called “self-improving collodion baby”, is a rare mild variant of autosomal recessive congenital ichthyosis and is defined as a collodion baby who shows the nearly complete resolution of scaling within the first 3 months to 1 year of life. However, during the neonatal period, it is not easy to distinguish SHCB from other inflammatory forms of autosomal recessive congenital ichthyosis, such as congenital ichthyosiform erythroderma. Here, we report a case study of two Japanese SHCB patients with compound heterozygous mutations, c.235G>T (p.(Glu791))/ c.1189C>T (p.(Arg397Cys)) and c.1295A>G (p.(Tyr432Cys))/ c.1138delG (p.(Asp380Thrfs13)), in CYP4F22, which encodes cytochrome P450, family 4, subfamily F, polypeptide 22 (CYP4F22). Immunohistochemically, inflammation with the strong expression of IL-17C, IL-36γ, and TNF-α was seen in the skin at birth. CYP4F22 is an ultra-long-chain FA ω-hydroxylase responsible for ω-O-acylceramide (acylceramide) production. Among the epidermal ceramides, acylceramide is a key lipid in maintaining the epidermal permeability barrier function. We found that the levels of ceramides with ω-hydroxy FAs including acylceramides and the levels of protein-bound ceramides were much lower in stratum corneum samples obtained by tape stripping from SHCB patients than in those from their unaffected parents and individuals without SHCB. Additionally, our cell-based enzyme assay revealed that two mutants, p.(Glu791) and p.(Arg397Cys), had no enzyme activity. Our findings suggest that genetic testing coupled with noninvasive ceramide analyses using tape-stripped stratum corneum samples might be useful for the early and precise diagnosis of congenital ichthyoses, including SHCB.

Multidimensional slit-scan detection of bladder cancer. Preliminary clinical results

A multidimensional slit-scan flow system was developed for the automated recognition of abnormal cells derived from cancer of the uterine cervix and its precursors. It provides great sensitivity in both its ability to recognize cellular abnormality and to deal with the myriad potential causes of false alarms in an automated flow system. While its initial application was the automated recognition of the spectrum of neoplasia in gynecologic cytology samples, a preliminary study was carried out using specimens obtained from the urinary bladder. Cellular material was collected by bladder irrigation and stained with the fluorochrome acridine orange. One hundred fifty-three bladder irrigation specimens, including 115 abnormal specimens containing cells derived from neoplastic lesions of the bladder epithelium, were analyzed. For the purposes of this study, abnormal specimens from the urinary bladder included specimens containing cells derived from the following lesions of the urothelium: dysplasia (atypical hyperplasia), carcinoma-in-situ, and transitional cell carcinoma, grades 1-3. Approximately 50,000 cells were analyzed for most specimens. Of the 38 presumed normal specimens (specimens containing only normal urothelial components), four were instrument classified abnormal. For the 69 specimens containing cells derived from transitional cell carcinoma, grade 1, 1-2, 2, 66 were correctly classified as abnormal while three were classified as normal.(ABSTRACT TRUNCATED AT 250 WORDS)
