Objective To explore the diagnostic value of ultrasound-guided aspiration biopsy in patients with unexplained refractory ascites.Methods The data of 25 cases of unexplained refractory ascites were retrospectively analyzed.For all the cases the diagnosis was based on the examination of contrast enhanced CT or ultrasound.Ultrasound-guided aspiration biopsy of locally thickened peritoneum or ti- ny masses in ascites was performed.Reults Ultrosonographic image of all cases was as follows.10 cases,with locally thickened peritone- um,were isoechoic or hypoechioc.In 2 of 10 cases contrast enhanced ultrasound examination was done,and the images were characterized by an obvious enhancement in arterial phase and quick wash-out in veinous phase.In 7 cases there was irregularly thickened peritoneum, accompanied by adhesion and caking of the omentum.Cystic formation in ascites or in peritoneum was found in 5 cases.Solid mass in asci- tes was found in 2 cases,and splenomegaly and enlarged pancreas were found in 1 case.Ultrasound-gnided aspiration biopsy was perfomed in all the patients.Among them 4 patients were operated on later.Histopathologic examination showed malignency in 20 patients.Among them,malignant peritoneal mesothelioma accoumted for 6 cases,pancreatic cystoadenoma in 2,mestastic adenocarcinoma in 9,malignant schwannoma in 1,lymphoma in 1,and histiocytoma in 1 patient.In the other 5 cases the lesion was benign,and it was verified by follow- up for about 6 months.Among them there were 3 cases of tuberculosis,1 case of inflammatory disease and 1 case of retroperitonesl fibro- sis.Conclusion Ultrasound-guided aspiration biopsy is valuable in the diagnosis of locally thickened peritoneum and tiny mass in ascitic fluid,and is valuable for diagnosis of unexplained refractory ascites.

In the present study, the genomic sequence characteristics of HN-JY40 strains of the hepatitis E virus (HEV) isolated from pigs in Henan Province, China, were analyzed and the evolutionary relationship between HN-JY40 and other sequenced strains examined. The whole genome of HN-JY40 was sequenced and analyzed by reverse transcription-polymerase chain reaction, 3' rapid amplification of cDNA ends (3' RACE) and 5' RACE. Bioinformatic analyses were carried out with Megalign, Expasy, clustal x, and MEGA 4 software. The genome of HN-JY40 was 7 223 bp in size upon removal of polyA sequences. Sizes were 9 bp and 69 bp at 5' and 3' noncoding regions, respectively. The genome of HN-JY40 was predicted to contain three open reading frames (ORFs): ORF1 (5 124 bp) encoding 1 707 amino acids; ORF2 (2 025 bp) encoding 674 amino acids; ORF3 (345 bp) encoding 114 amino acids. Phylogenetic-tree analyses indicated that HN-JY40 is a typical type-IV virus that belongs to a new subgenotype of HEV genotype 4. We sequenced and analyzed the whole genome of HN-JY40. This strategy elicited the genomic characteristics of the HEV isolated from pigs in Henan Province as well as the evolutionary relationships between HN- JY40 and other HEV isolates from pigs. We revealed that the ORF1 of HN-JY40 (153-432 nt) and human HK 104-2004 had high similarity, which offers molecular evidence for uncovering the interspecies transmission of the HEV.

Objective To investigate the pathogenesis of small cell lung cancer ( SCLC) and to ex-plore the expression of cell cycle related kinase ( CCRK) in SCLC and its clinical significance.Methods Reverse transcription polymerase chain reaction ( RT-PCR) and Western blot were performed to examine ex-pression of CCRK in SCLC and normal tissues.Results The expressions of gene [(0.51 ±0.11)IU/L] and protein [(0.61 ±0.13)IU/L] of CCRK in SCLC tissues were significantly higher than normal tissues [(0.30 ±0.08)IU/L, (0.34 ±0.09)IU/L] ( P <0.05).The expression of CCRK was closely correlated with the clinical curative effect ( P <0.05 ) rather than the clinical stages ( P >0.05 ) .Conclusions The expressions of gene and protein of CCRK in SCLC tissues were significantly higher than normal tissues. CCRK promoted the occurrence and progress of SCLC.Chem can restrain effectually the excessive expres-sion of CCRK.The expressions of gene and protein of CCRK in the different clinical curative effect group had significant difference.

Objective To investigate the effect of sub-anesthesia dose of isoflurane in 60％ oxygen on acute lung injury in aged rats with sepsis.Methods Ninety male Sprague-Dawley rats,aged 12-14 months,weighing 500-800 g,were divided into 3 groups (n=30 each) using a random number table:sham operation group (Sham group),sepsis group (S group),and sepsis plus isoflurane plus oxygen treatment group (S+I+O group).Sepsis was induced by cecal ligation and puncture in S and S+I+O groups.In group S+I+O,0.7％ isoflurane in 60％ oxygen was inhaled for 1 h starting from 1 and 6 h after operation.Eighteen rats were selected in each group and observed for 7 days after operation,and the survival rate was recorded.Six rats were selected in each group at 24 h after operation,and bronchoalveolar lavage fluid (BALF) was collected to determine the protein concentrations (by BCA protein assay),blood samples were collected from the femoral artery for blood gas analysis,PaO2 was recorded,and the oxygenation index was calculated.Six rats in each group were sacrificed at 24 h after operation,the left lung specimens were obtained and stained with hematoxylin and eosin for examination of pathological changes,the right lung specimens were obtained for determination of wet to dry weight ratio (W/D ratio),and blood samples were collected from the right atrium for measurement of the concentrations of interleukin-1β (IL-1β),IL-6,tumor necrosis factor-α (TNF-α),high-mobility group box 1 protein (HMGB1) and IL-10 in serum (by enzyme-linked immunosorbent assay).Results Compared with group Sham,the survival rate was significantly decreased,and the concentrations of IL-1β,IL-6,TNF-α,HMGB1 and IL-10 in serum were increased in S and S+I+O groups,and W/D ratio and protein concentrations in BALF were significantly increased,and the oxygenation index was decreased in group S (P＜0.05).Compared with group S,the survival rate was significantly increased,W/D ratio and protein concentrations in BALF were decreased,the oxygenation index was increased,the concentrations of IL-1β,IL-6,TNF-α and HMGB1 in serum were decreased,and the concentration of serum IL-10 was increased (P＜0.05),and the pathological changes were significantly attenuated in group S+I+O.Conclusion Sub-anesthesia dose of isoflurane in 60％ oxygen can reduce acute lung injury in aged rats with sepsis,and the mechanism may be ralated to inhibiting systemic inflammatory responses.

Objective:To investigate the expression of CDK6 and FOXM1 in peripheral T-cell lymphoma (PTCL), and its correlation with clinicopathologic features and patient prognosis.Methods:The Oncomine was used for data mining and analyzing the expression levels of CDK6 and FOXM1 in PTCL. Immunohistochemistry (IHC) of EnVision method was used to detect the expression of CDK6 and FOXM1 proteins in 166 cases of PTCL diagnosed at Shanxi Provincial Cancer Hospital from January 2016 to December 2018, and 30 cases of lymph node with reactive hyperplasia as control.Results:Among the PTCL patients, 104 were male and 62 were female, aged from 3 to 85 years, with an average age of 53 years. Analyses of the Oncomine 4.5 database showed that mRNA expression of CDK6 and FOXM1 in PTCL tissues was significantly higher than that in normal tissue ( P<0.05). IHC staining showed the positive rates of CDK6 and FOXM1 proteins in PTCL tissues were 27.7% (46/166) and 80.7% (134/166), respectively. The expression was mainly present in the nuclei of tumor cells, showing a diffuse, strongly positive pattern. The positive rates of CDK6 and FOXM1 proteins among the 30 cases of lymph-node reactive hyperplasia were 0 (0/30) and 30% (9/30), respectively. The expression of FOXM1 was mainly found in the lymphoid follicle germinal center, and not present in the T-zone cells. CDK6 protein, FOXM1 protein and the co-expression of CDK6 and FOXM1 proteins in PTCL were associated with higher Ann Arbor staging and international prognostication index score ( P<0.05), and inversely associated with overall survival ( P<0.05). Meanwhile, CDK6 protein expression was positively correlated with FOXM1 protein expression ( P<0.05). Conclusions:CDK6 and FOXM1 may be new targets for the diagnosis and treatment of PTCL. The overexpression of CDK6 may lead to enhanced function of the transcription factor FOXM1, while the overexpression of CDK6 and FOXM1 also promotes the development and progression of PTCL.
