Objective To evaluate the clinical efficacy of early enteral nutrition combined with additional parenteral nutrition (EEN + PN) versus TPN (total parenteral nutrition) in patients after conventional pancreaticoduodenectomy (PD).Methods From January 2009 to January 2013, 340 consecutive patients who underwent conventional PD with Child's reconstruction at the First Affiliated Hospital of Xi'an Jiaotong University were enrolled into this single-center retrospective comparative study.There were 87 patients in the EEN + PN group and 253 patients in the TPN group.The preoperative baseline characteristics,histopathological types, intraoperative parameters and postoperative outcomes were recorded and compared between the two groups.Results There were no significant differences in the preoperative general characteristics data, pathological patterns, and intraoperative details.There were significantly higher rates in delayed gastric emptying (DGE), morbidity (15.9％ vs 6.7％, P ＜ 0.05), and pneumonia (10.3％ vs 3.6％, P ＜ 0.05);significantly prolonged nasogastric tube removal time (5.6 ± 0.2 days vs 3.9 ± 0.1 days, P＜0.05), and increase in hospitalization expenses (65 397.0 ± 861.2) Yuan vs (50 663.9 ± 239.2) Yuan, P ＜ 0.05) in the EEN + PN group when compared with the TPN group.Conclusions EEN + PN after conventional PD was associated with increased rates of DGE and pneumonia, prolonged nasogastric tube removal time, longer EN duration and increase in hospitalization expenses.Hence, EEN should only be performed prudently and selectively.

OBJECTIVETo detect FLG gene mutations in 10 families affected with ichthyosis vulgaris and to explore mutational hot spot of the FLG gene in Chinese Han population.

METHODSPCR and direct sequencing were carried out to identify potential mutations of the FLG gene in above families. One hundred healthy individuals were analyzed as normal controls.

RESULTSThree mutations (3321delA, 5757delCCAG and S2706X) were identified in 7 families. A homozygous mutation 3321delA was also detected in two unrelated patients. No mutations were found in the remaining three families. Neither of the null mutations (5757delCCAG and S2706X) was found in the 100 controls. However, for 3321delA, a heterozygous mutation was also found in two of the controls.

CONCLUSIONThree FLG mutations have been identified in the selected families with ichthyosis vulgaris, and the 3321delA mutation was most prevalent (46.9%). Mutations 5757delCCAG and S2706X were first found in patients with ichthyosis vulgaris. Other candidate genes may underlie the disease in those without a FLG mutation.

OBJECTIVETo detect the genomic deletion mutation in the NEMO gene of a family with incontinentia pigmenti (IP; MIM 308310).

METHODSA pedigree of IP was investigated. By using long PCR, the Delta4-10 deletion in NEMO gene was tested with specific primers In2/JF3R, and Delta4-10 deletion in pseudogene DeltaNEMO was investigated with primers Rev-2/JF3R. NEMO gene of 80 normal controls was also tested.

RESULTSThe deletion of exons 4-10 in both NEMO gene and the pseudogene DeltaNEMO was detected in all the patients in the family, but was not found in the normal individuals in this IP family and 80 unrelated controls.

CONCLUSIONThe study showed that the family with IP, which showed anticipation, was caused by NEMODelta4-10 deletion in the NEMO gene. Long PCR analysis is proven to be an efficient tool for identification of NEMO rearrangements. It could provide useful information for the genetic counseling of the family involved.

Alopecia is a common disease in dermatologic clinics.The diagnosis of some hair diseases does not rely on pathological examinations,and with the development of science and technology,the role of many new non-invasive detection instruments,such as dermoscopy,hair scanners and skin CT,is increasingly valued in the diagnosis and treatment of hair diseases.However,the role of pathological examination is still irreplaceable.Because of the particularity of hair diseases,hair pathology differs from common skin pathology in the aspects of scalp biopsy sites,biopsy methods and techniques,tissue-slicing methods and pathological report content.This review systematically discusses the role of scalp pathological biopsy in the diagnosis and treatment of alopecia.

Frontal fibrosing alopecia is a primary lymphocytic cicatricial alopecia, and is generally considered to be a subtype of lichen planopilaris due to similar histopathological changes. Its etiology is still unclear. With the deepening of research on this disease, more and more cases of frontal fibrosing alopecia have been reported in China and other countries. This review summarizes research progress in pathogenesis, clinical and pathological characteristics, and treatment of frontal fibrosing alopecia.

A case of cicatricial female pattern hair loss was reported. A 36-year-old female patient presented with gradually aggravated hair loss for more than 10 years. Skin examination showed diffuse hair thinning on the scalp, thin and soft hairs, and some pencil eraser-sized areas of focal atrichia. TrichoScan examination revealed markedly decreased hair density on the forehead, variability in hair diameter greater than 20%, and increased proportions of vellus hairs. Dermoscopic examination showed increased numbers of vellus hairs, plenty of focal atrichia areas measuring 3 - 5 mm in diameter, loss of some follicular ostia, and confluent white dots. Histopathological examination of vertical and transverse scalp sections showed predominantly distributed miniaturized hair follicles with lichenoid folliculitis around the infundibulum and isthmus, concentrically layered perifollicular fibrosis, a marked decrease in the number of hair follicles compared with healthy people of the same age, increased proportions of vellus hairs, a large number of miniaturized hair follicles and follicular streamers, and formation of follicular micro-scars. The patient was diagnosed with cicatricial female pattern hair loss. She received topical treatment with 5% minoxidil liniment once a day, and alternate treatment with topical tacrolimus ointment and clobetasol propionate ointment, as well as oral spironolactone at a dose of 20 mg twice a day and compound glycyrrhizin capsules at a dose of 50 mg thrice a day. After half a year of treatment, there was no marked aggravation of hair loss, and the follow-up continued.

OBJECTIVETo detect mutations of ATP2A2 gene in a pedigree and a sporadic case with Darier disease (DD) and explore the underlying molecular mechanism.

METHODSClinical data of the pedigree and the sporadic case were collected. Genomic DNA was extracted from blood samples of four members from the pedigree (including three patients and one healthy member), the sporadic case and 100 healthy controls. PCR was performed to amplify all coding exons of the ATP2A2 gene. And the products were directly sequenced to detect mutations.

RESULTSA missense mutation c.1484C>T (p.S495L) in exon 12 was detected in all patients of the pedigree. For the sporadic case, a novel splicing mutation c.325-2A>G was detected at the junction between intron 4 and exon 5. The same mutations were not found in the 100 healthy controls.

CONCLUSIONMutations of the ATP2A2 gene may lead to the occurrence of DD in both familial and sporadic cases with DD.

A case of fibrosing alopecia in a pattern distribution (FAPD) and its clinicopathological, dermoscopic and TrichoScan features were reported to improve the understanding of FAPD. A 23-year-old male patient presented with progressive hair loss on the forehead and top of the head for 10 years, local hair thinning and softening, and occasional scalp itching. Skin examination showed diffuse sparseness of hair from the forehead to the top of the head, frontal hairline recession, focal thinning and softening of hair, some follicular keratotic papules and perifollicular erythema on the alopecic area, with no obvious scales. TrichoScan examination revealed markedly decreased hair density and increased proportions of vellus hairs. Dermoscopy showed loss of some follicular ostia and confluent white dots. Histopathological examination of the scalp showed lichenoid lymphocytic infiltration around the infundibulum and isthmus of hair follicles, concentrically layered perifollicular fibrosis, hair follicle destruction, formation of follicular micro-scars, markedly increased variation in the diameter of residual follicles, and some vellus hairs. The patient was diagnosed with FAPD. FAPD is easily misdiagnosed as androgenetic alopecia, and early diagnosis and treatment are needed.

Objective: To observe the expression of long-chain non-coding RNA (lncRNA) RP3-340N1.2 in breast cancer tissues and its effect on proliferation and migration of breast cancer MCF-7 cells, and to explore the possible mechanism. Methods: 13 pairs of breast cancer tissues and adjacent tissues from breast cancer patients, who underwent radical surgery at the Cancer Center of theAffiliated People’s Hospital of Hubei University of Medicine from Jan. 2017 to Sep. 2017, were collected for this study. qRT-PCR was used to detect the differential expression of RP3-340N1.2 in collected tissue samples and breast cancer cell lines and normal breast epithelial cell line. RP3-340N1.2 plasmid (experimental group) and the negative control plasmid (control group) were transfected into breast cancer MCF-7 cells using Lipofectamine 3000. Cell counting (CCK-8) and Transwell migration assay were used to examine the effect of RP3-340N1.2 over-expression on proliferation and migration of MCF7 cells, the effect of RP3-340N1.2 over-expression on the mRNA expression of miR-134-5p and OPCML was detected by qRT-PCR, and Western blotting was used to detect the expression of OPCML protein. Results: The expression of RP3-340N1.2 in breast cancer tissues was significantly lower than that in adjacent tissues ( P <0.01), and the expression of RP3-340N1.2 in breast cancer cell lines was significantly lower than that in normal breast epithelial cells ( P < 0.01). Up-regulation of RP3-340N1.2 decreased the proliferation and migration of MCF7 cells (all P <0.05). After over-expression of RP3-340N1.2 in MCF7 cells, the expression of miR-134-5p obviously decreased ( P <0.01); moreover, the mRNA and protein expressions of OPCML significantly increased ( P <0.01) while the expressions of cell cycle regulatory proteins (CDK4, Cyclin D2) and cell migration regulatory proteins (Vimentin and N-cadherin) decreased significantly (all P <0.01). Conclusion: RP3-340N1.2 is low expressed in breast cancer tissues and cell lines. Up-regulation of RP3-340N1.2 expression can lead to decreased expression of miR-1345p and increased expression of OPCML gene, thereby inhibiting the proliferation and migration of breast cancer cells.
