ABSTRACT
Objective:To analysis of clinical and imaging characteristics of pulmonary cryptococcosis.Methods:The clinical and imaging characteristics of 113 patients with pulmonary cryptococcosis who were admitted to the Second Affiliated Hospital of Zhejiang University School of Medicine from January 2014 to March 2019, were retrospectively analyzed.Results:Among 113 patients, 74 cases (65.5%) were males, and 71 cases (62.8%) were at a age of 40-60 years. The imaging manifestations showed a nodular-infiltrating patchy mixed type ( n=44,38.9%), accompanied by halo sign ( n=48, 42.5%) and bronchial air sign ( n=48, 42.5%). All patients were treated with fluconazole and the follow-up at 3 months after discharge showed their conditions were all improved. Subgroup analysis showed that patients with complications had older average age [(54.28±10.64)y vs. (46.52±12.12)y, t=-5.05, P<0.001], longer hospital stay [(10.42±6.11)d vs. (7.09±5.63)d, t=-4.28, P=0.007], lower white blood cell count [(6.02±2.16)×10 9/L vs. (6.96±2.29)×10 9/L, t=2.44, P=0.027]. The symptomatic group had fewer male patients [56.2% (45/80) vs. 87.9% (29/33), χ 2=19.54, P<0.001], and imaging was more likely to show infiltrative patchy [32.5%(26/80) vs. 9.1%(3/33), χ 2=18.25, P=0.031]. There was no significant difference in clinical and imaging manifestations between antigen positive group and antigen negative group(all P>0.05). Conclusions:Most of the patients with pulmonary cryptococcosis are middle-aged men, and have nodular-infiltrating patchy mixed type in imaging; the complications would prolong the length of hospital stay.
ABSTRACT
Bardet-Biedl syndrome (BBS) is a rare and highly heterogeneous autosomal recessive disease caused by ciliary structure abnormality or dysfunction. Here we report a case of a 23-year-old woman who was diagnosed with BBS with a rare BBS10 gene mutation. Literature review was performed with a focus to outline treatment and management plans for patients with this rare and potentially dangerous disease.
ABSTRACT
Objective To analyze the characteristics of skeletal muscle cells gene markers in septic patients by using bioinformatics. Methods The differential gene expression of marker microarrays (GSE13205) in skeletal muscle tissue of patients with sepsis was obtained from gene expression omnibus (GEO) database of National Center for Biotechnology Information (NCBI). Gene differential expression analysis was carried out using online GEO2R provided by NCBI. Data processing, analysis and mapping were carried out using online bioinformatics array research tool (BART) and Cytoscpe software, the software of the national resource for network biology. Functional annotation and pathway analysis of differential expression genes were performed using Kyoto encyclopedia of genes and genomes (KEGG) and gene ontology (GO) provided by the database for annotation, visualization and integrated discovery (DAVID), and protein interaction analysis was further performed in search tool for the retrieve of interacting genes/proteins (STRING-DB). Results The TOP250 genes were extracted from the GSE13205 dataset. A total of 242 differentially expressed genes were included in the analysis. Among them, 78 up-regulated genes and 164 down-regulated genes were identified. After extensive data analysis, these differentially expressed genes were enriched into different biological processes or subsets of molecular functions, mainly enriched in the positive and negative regulation of growth, mineral absorption and other pathways. The 14 most closely related genes among differentially expressed genes were identified from the protein interaction network. Conclusion The differential expression genes in patients with sepsis were mainly concentrated on cell growth and apoptosis and mediating tumor-related immune function regulation.

ABSTRACT
Objective To investigate the correlation and clinical diagnosis significance between ultrasound elastography and the distribution of myofibroblast in breast tumor.To assess the value of ultrasonic elastography and myofibroblast in the diagnosis of breast cancers.MethodsThree-hundred and fifteen patients recruited from May 2009 to November 2010 were divided into benign group and malignant group according to postoperative pathological diagnosis results considered as gold standard.The clinical value of the score of ultrasonic elastography was evaluated.The expression levels of CD34 and α-SMA protein in breast tissues were examined by immunohistochemistry.ResultsThe difference was statistically significant for the expression level of CD34 and α-SMA between malignant breast tumor patients compared with benign ( P ＜0.05).The expression level of CD34 was lower,but α-SMA was higher in the patients of breast cancer compared with benign tumor.However,the expression level of CD34 and α-SMA was just the opposite in the patients of benign tumor.The expression level of CD34 was the negative correlation with the elastography score ( P ＜0.05) in the breast tumor,but α SMA just the opposite situation.Conclusions The score of ultrasound elastography can represent MFS distribution characteristics in breast tumors in the result that α-SMA +/CD34- can determine the existence of myofibroblast.
ABSTRACT
AIM: To investigate the effect of dihydroartemisinin (DHA) on the proliferation of murine T lymphocytes stimulated by Con A in vitro and its related immunosuppressive mechanism. METHODS: Murine T lymphocytes were stimulated by Con A and treated with different concentrations of DHA. Cell proliferation was measured by carboxyl fluoresce in diacetate succinmidyl ester (CFDA-SE) staining. The expression of CD69, CD25 and CD71,which was the marker of early, middle, later activation of CD3~+ T lymphocytes, was measured by flow cytometry (FCM) combined with two-color immunofluorescent staining of cell surface antigen. Fluorescence calcium indicator fluo-4/AM was used to measure the change of the intracellular calcium concentration ([Ca~(2+)]_i) of murine T lymphocytes. The distribution of the cell cycle was analyzed by PI staining. The expression of CD69, the early activation antigen on CD4~+CD25~(high) Treg was also measured by FCM combined with three-color immunofluorescent staining. RESULTS: The result of CFDA-SE staining showed that DHA efficiently inhibited the Con A-induced proliferation of T-lymphocytes in a time-and dose-dependent manners. DHA showed modestly increased proportions of CD69 and CD25 on Con A-stimulated CD3~+T cells, but inhibited the expression of CD25 in a dose dependent manner. DHA with Con A, but not DHA alone, caused an increase in intracellular calcium concentration of T cells. The results of FCM analysis with PI staining showed that DHA imposed a total cell cycle arrest in G_0/G_1 and prevented cells entering S phase and G_2/M phase. Furthermore, DHA reduced the expression of CD69 on CD4~+CD25~(high) Treg. CONCLUSION: DHA, which exhibits immunosuppressive effect on the proliferation of murine T-lymphocytes, is promising to be developed as an immunosuppressive reagent.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the clinicopathological, immunohistochemical, and molecular biologic characteristics of esophageal stromal tumors and smooth muscle tumors.</p><p><b>METHODS</b>Twenty four cases of esophageal mesenchymal tumors were reclassified by a panel of antibodies such as CD117, CD34 etc. The sequence of 11 exon of c-kit gene were detected in some cases.</p><p><b>RESULTS</b>There were 3 cases of esophageal stromal tumors, 20 leiomyomas, and 1 leiomyosarcoma. The 3 esophageal stromal tumors occurred in 3 men aged 71, 56 and 60 years respectively. The tumors originated from muscularis propria with the size of 4 cm, 8 cm and 14 cm in diameter. Microscopically, the tumor cells were spindle and epithelioid shaped with slightly basophilic appearance, arranged in intersecting fascicles, diffusing and palisading patterns. Immunohistochemically, the tumors were positive for CD117 and CD34. The mutation of 11 exon of c-kit gene was detected in one case. In comparison, esophageal leiomyomas occurred in a younger population. The age ranged from 30 to 60 years (mean age 41.6 years), 12 male cases, 8 female cases. 15 cases of esophageal leiomyomas were intramural tumors with a diameter of 0.8 - 10.5 cm (mean 4.5 cm) originating from muscularis propria and 5 cases which were intraluminal polyps with a diameter of 0.2 - 1.0 cm originating from muscularis mucosae. Leiomyomas were strongly eosinophilic in appearance, diffuse positivity for alpha-SMA, MSA, and desmin, and no c-kit gene mutation. One male case of leiomyosarcoma had a diameter of 5 cm and originated from muscularis mucosae and displayed a sausage-shaped polyp.</p><p><b>CONCLUSIONS</b>Leiomyoma is still the most common mesenchymal tumor of the esophagus, the stromal tumor can be similar to gastrointestinal stromal tumors. Typical esophageal leiomyosarcoma is very rare and has different clinicopathologic and molecular biologic features.</p>

ABSTRACT
Objective To block the bio function of TGF ? by the application of anti TGF ? polyclonal antibody, and observe its efficacy of prevention of abdominal adhesion. Methods The postoperative abdominal adhesion model was established in SD rats. The drugs were administrated by abdominal injection with saline (control group), sodium hyaluronate( HA group), and varied dosage of anti TGF? (anti TGF? groups) respectively. The adhesion was scored 21days later, while 30 of them were executed on the day 3 and day 10 after operation respectively. The expression of TGF ? was checked by immunohistochemistry in the samples obtained from the adhesion sites. Results The score of adhesion in anti TGF ? group (2.4?0.99) was significantly lower than that in control group (6.0?1.25) and HA group (3.4?1.03); in different dosage of anti TGF, the 50?g group showed its economical efficacy; in the control and HA groups the expression of TGF ? had a time dependent manner, which reachs to maximum in the day 3, and could be reduced by antibody. Conclusions The polyclonal antibody of TGF ? shows the power to prevent the postoperative abdominal adhesion in animal model, the mechanism of which is due to inhibition of TGF ? expression.
