Objective To study the clinicopathologic characteristics of pulmonary sclerosing hemangioma(SH).Method Eleven cases of SH were studied by the clinical data and immunohistochemistry and review of the literature.Results SH has a characteristic architecture composed of round cell and surface cubic cell.It has a variety of tissular structure,mainly expression with four regions that contain solid regions,papillary regions,angiomatoid regions and sclerosing regions.Immunohistochemically,these two kinds of cells were both positive for TTF-1 and EMA.Conclusions SH is a tumor that originates from the epithelial cell of primary respiratory tract.Both the solid round cells and surface cubic cells are neoplastic.SH should differentiate with inflammatory,typeⅡpneumocyte papillary tumor,alveolus adenoma and typical carcinoid tumors.The parts of SH have invade grow tendency.Surgical cure of SH is suited for operating a lobe of the lung but not just peel of the tumor.

Objective To assess the efficacy of different internal fixations of palatal fracture.Methods Seventy-four patients with palatal fracture admitted between October 2007 and October 2013 were reviewed retrospectively.Through out-patient follow-up,postoperative occlusion and palatal complications were examined and fracture healing was evaluated using CT scan.Results Palatal type Ⅰ-Vfractures involved in 8 patients (11％),14 patients (19％),26 (35％),12 patients (16％),6 patients (8％),and 8 patients (11％) respectively.Forty-three patients were available to follow-up,including 31 patients with good or acceptable occlusion.All wounds healed without palate associated infections,plate exposure or oronasal fistula.Of the 27 patients classified as type Ⅱ,Ⅲ and V sagittal palatal fractures,both nasomaxillary and zygomatico-maxillary struts fixation (n =17) and isolated zygomatico-maxillary struts fixation (n =10) had insignificant differences in success rate as to occlusion assessment (82％ vs 80％,P ＞0.05).Whereas compared with isolated vertical buttress fixation (n =15),additional immobilization of horizontal alveolar buttresses (n =12) had significantly higher success rate (100％ vs 67％,P ＜ 0.05).Conclusion Complete rigid fixation at early stage,including vertical buttress fixation,in particular the zygomatico-maxillary struts,and horizontal alveolar buttress fixation can achieve satisfactory outcome.

Objective To investigate cancer patients′nutritional status after operative treatment and analysis of risk factors for malnutrition, which provides the basis for maintaining patients′ nutrition support after discharge. Methods One hundred and thirty patients treated with tumor in Liuan Hospital affiliated to Anhui Medical University were investigated. The nutritional status of patients discharged from hospital was evaluated by subjective comprehensive assessment, and the risk factors of malnutrition when they were discharged from hospital were analyzed. Results In 130 patients, 76 patients (58.46%) were assessed as no or mild malnutrition, and 54 patients (41.54%) as moderate or severe malnutrition. Univariate analysis showed that body mass index < 18.5 kg/m2 at admission, nutritional risk screening 2002(NRS2002) ≥ 3 scores, smoking and drinking were related to the occurrence of malnutrition after tumor surgery (P<0.05). Logistic regression analysis showed that NRS2002≥3 scores at admission and smoking were independent risk factors for malnutrition at discharge (P < 0.05). Conclusions The incidence of malnutrition in patients after tumor surgery is high, and there are many risk factors. Therefore, early nutrition support should be provided to patients, and family nutrition intervention after discharge is also very necessary.

Objective: To investigate the incidence rate of nutritional risk and malnutrition in patients with acute cerebral infarction, and analyze the influence factors of nutritional risk and malnutrition, so as to provide evidence for targeted nutritional intervention. Methods: Nutritional risk screening 2002 (NRS2002), subjective global assessment (SGA) and body mass index (BMI) were applied to screen nutritional risk and assess nutritional state for hospitalized patients with acute cerebral infarction from January to October 2017, and to investigate the incidence rate of nutritional risk and malnutrition. Univariate analysis was used to analyze the relationship of nutritional risk and malnutrition with the basic information and habits of patients. Logistic regression was used to analyze the independent risk factors. Results: The incidence rate of the nutritional risk (NRS2002 ≥ 3 scores) was 61.0% (122/200) in 200 cases of acute cerebral infarction patients. If BMI<18.5 kg/m² was used to evaluate the nutritional deficiencies, the incidence rate of undernutrition was 8.5% (17/200). The incidence rate of malnutrition was 25.5% (51/200) using the SGA evaluation method. The univariate analysis showed that the nutritional risk was associated with age, drinking, combined infection, fluid diet, dysphagia/cough, and BMI (<18.5 kg/m²)(P<0.05 or<0.01), and the malnutrition was associated with age, combined infection, disturbance of consciousness, fluid diet, dysphagia/cough and BMI (<18.5 kg/m²) (P<0.01). Logistic regression analysis showed that the age, fluid diet were the independent risk factors for nutritional risk (P<0.05 or<0.01). The age, combined infection, fluid diet and BMI (<18.5 kg/m²) were the independent risk factors of malnutrition (P<0.05 or<0.01). Conclusions The incidence of nutritional risk and malnutrition in patients with acute cerebral infarction is relatively high. Nutritional risk screening and nutritional assessment should be performed at the time of admission. Early nutrition intervention should be used to prevent malnutrition and improve the prognosis of patients.

OBJECTIVE: To analyze the application of three-dimensional power Doppler sonography (3-DPDS) in evaluation of the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) in second-trimester fetus. METHODS: Three-dimensional volume probe was used to collect the 3-DPDS blood flow images in 50 normal fetuses of 22-24 weeks and 50 fetuses of 30-32 weeks, respectively. The characteristics of three-dimensional ultrasound were analyzed. The clinical and imaging data of 4 fetuses of 26-32 weeks with midgut volvulus were analyzed retrospectively. RESULTS: The display rates of SMA and SMV were 93%in normal group by 3-DPDS and those in volvulus group were 4/4 and 3/4, respectively. The SMV trunk was parallel to and on the right side of the SMA in the normal group, while 3 cases in volvulus group showed the characteristic relationship of SMV swirling around SMA. CONCLUSIONS 3-DPDS can be used to observe the spatial relationship of SMA and SMV visually in fetus during the second trimester and is of value to diagnose and predict the outcome of midgut volvulus.

OBJECTIVE: To analyze transforming growth factor-β1( TGF-β1)-induced differentially expressed genes( DEGs) in human embryonic lung fibroblast( IMR-90) using microarray,and to screen the key genes and signaling pathways related to trans-differentiation of fibroblast.METHODS: The gene chip GSE17518,attained from TGF-β1 stimulated IMR-90 cells,was downloaded from the Gene Expression Omnibus database.The DEGs were screened by GENE-E software.Then,the DEGs were imported into the DAVID online database for Gene Ontology( GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes( KEGG) pathway enrichment analysis.The proteinprotein interaction( PPI) network was constructed and the hub genes were screened using STRING database and Cytoscape software.RESULTS: A total of 394 DEGs related to TGF-β1 stimulation were identified,including 171 down-regulated genes and 223 up-regulated genes.The results of GO analysis showed that the DEGs were widely distributed in cytoplasm,cell membrane,extracellular matrix( ECM) and exosomes,regulating biological functions such as ECM organization,cell migration and adhesion,cell proliferation and apoptosis.The results of the KEGG pathway analysis indicated that most of DEGs were enriched in cell focal adhesion,ECM-receptor interaction and phosphoinositide 3 kinase-Protein kinase B( PI3K-Akt) signaling pathways.The PPI network screened 10 core genes,included nucleolar protein 2( NOP2),succinate dehydrogenase B,glutamyl-prolyl-tRNA synthetase( EPRS),FtsJ homolog 3( FTSJ3),prefoldin subunit 4,Ras-related C3 botulinum toxin substrate 2,signal recognition particle receptor subunit beta,succinate-Co A ligase GDPforming beta subunit,pumilio RNA binding family member 3( KIAA0020),and general vesicular transport factor p115.NOP2,EPRS,FTSJ3,KIAA0020 were mainly distributed in M1 module.The NOP2 is the core gene with the highest number of nodes in M1 module.CONCLUSION: A total of 10 core differential genes and 7 signaling pathways related to TGF-β1 stimulation were screened.Among them,focal adhesion,ECM-receptor interaction,PI3K-Akt and NOP2,EPRS,FTSJ3,KIAA0020 may provide new direction for research of mechanisms of abnormal activation of fibrotic diseases including silicosis in incidence and development of multiple lung fibrotic diseases.

OBJECTIVE: To investigate the differentially expressed microRNAs(miRNAs) in human embryonic lung fibroblast MRC-5 cells stimulated by transforming growth factor-β1(TGF-β1) using microarray chip, and screen for key genes and signaling pathways of fibroblast trans-differentiation. METHODS: The miRNA expression gene chip dataset GSE43992 on TGF-β1 stimulated MRC-5 cells were downloaded from high-throughput Gene Expression Omnibus(GEO) database of National Center for Biotechnology Information of the United States. The R language Limma package was used to screen the differentially expressed miRNAs. Corresponding target genes were predicted by miRWalk database performed by Gene Ontology(GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) signaling pathway enrichment analysis. The protein-protein interaction(PPI) network was constructed by the search tool for the Retrieval of Interacting Genes database. RESULTS: A total of five differentially expressed miRNAs were identified, including four up-regulated miRNAs and one down-regulated miRNA; and 42 corresponding differentially expressed target genes were predicted. GO analysis indicated that the target genes were significantly enriched in collagen catabolic process, extracellular matrix organization, membrane organization, collagen fibril organization, and cellular response to amino acid stimulus. The results of KEGG pathway analysis showed that the signaling pathways corresponding to miRNAs and target genes were mainly concentrated in 18 signaling pathways, that were mainly related to the age-ethnic signaling pathways and protein digestion and absorption miRNAs in tumors and diabetic complications. The core genes transfected into the myofibroblasts by the three fibroblasts screened by the PPI network were threonine kinase 1, estrogen receptor 1 and β-catenin. CONCLUSION: Five differentially expressed miRNAs, 42 target genes, 18 signaling pathways, and 3 core genes related to TGF-β1-induced MRC-5 cell trans-differentiation were screened. It can provide new reference for the treatment and research of many diseases including pneumoconiosis and pulmonary fibrosis.

OBJECTIVE：To study the improve ment effect of salvianolate on renal interstitial fibrosis （RIF）model rats and its possible mechanism. METHODS ：Totally 50 male SD rats were randomly divided into normal group ，model group ，losartan group （positive control group ，9 mg/kg）and salvianolate low-dose and high-dose groups （18，36 mg/kg）according to body weight ，with 10 rats in each group. Except for normal group ，other groups were given adenine 250 mg/kg intragastrically to establish RIF model. After modeling ，administration groups were given relevant medicine intragastrically ，and normal group and model group were given constant volume of normal saline intragastrically ，the volume was 10 mL/kg，once a day ，for consecutive 30 days. After last medication，the serum levels of creatinine （Scr），urea nitrogen （BUN）and 24 h proteinuria （24 h UPro ）were detected by ELISA. HE staining and Masson staining were used to observe the histopathological characteristics and fibrosis of the kidney. The degree of renal tubular injury and glomerulosclerosis were scored ，and the percentage of positive staining area of renal tissue was calculated ； immunohistochemistry and Western blot assay were used to determine the protein expression of Wnt 5a，Wnt5b，and β-catenin. RESULTS：Compared with normal group ，Scr，BUN and 24 h UPro levels ，renal tubular injury score ， glomerulosclerosis score ， the percentage of positive staining area in renal tissue ，the protein expression of Wnt 5a and β-catenin were increased significantly in model group （P＜0.05），while the expression of Wnt 5b protein was decreased significantly （P＜0.05）. Pathological changes such as mesangial hyperplasia ，fibrous tissue increase and inflammatory cell infiltration were observed under microscope. Compared with model group ，above indexes of rats were improved significantly in losartan group ，salvianolate low-dose and high-dose groups （P＜ 0.05），and the effect of salvianolate had dose-dependent trend. CONCLUSIONS ：Salvianolate has the improvement effect on RIF model rats induced by adenine ，and its mechanism may be related to inhibition of Wnt/ β-catenin signal pathway.

In order to prepare antioxidant peptide through hydrolyzing low-value protein resources with bacterial extracellular proteases and to discover novel proteases, crude extracellular protease from Pseudoalteromonas sp. SHK1-2 was obtained through fermentation which was used to hydrolyze collagen extracted from Cirrhinus molitorella skin. Small peptide fraction was isolated from hydrolysate by ultrafiltration and Sephadex LH-20 size exclusion chromatography and showed 1, 1-diphenyl-2-picrylhydrazyl radical scavenging activity (35.6%±7%), oxygen radical absorbance capacity and inhibition of DNA oxidation damage. The molecule weight was 776.2 Da, and amino acid sequence was Thr-Ala-Gly-His-Pro- Gly-Thr-His through liquid chromatography mass spectrum. Our findings suggest that peptide obtained from low-value protein of fish waste by hydrolysis with bacterial protease has antioxidant activity.
