A 70-year-old female patient presented with several cutaneous masses on the left neck and trunk for 40 years. Some masses were removed by surgical operation more than 10 years prior to the presentation, but recurred subsequently along with an increase in lesion number. Persistent dull pain emerged at the lesion sites 2 months prior to the presentation and the masses on the left neck ulcerated 10 days prior to the presentation. Histopathology showed tumor cell clumps in the dermis with benign eccrine spiradenoma components in the centre region and carcinomatous components in the periphery. The carcinomatous components included slightly atypical cells and hyaline degeneration. Immunohistochemically, carcinoembryonic antigen and epithelial membrane antigen were observed in the tumor tissues. The case was diagnosed as eccrine spiradenocarcinoma. The masses were surgically removed, but recurred 1 month later, increased in size and number and ulcerated 3 months later, and the patient died 6 months after the surgery.

Objective To analyze clinicopathologic features of sebaceoma. Methods Clinical, pathologic and immunohistochemical findings from 31 cases of sebaceoma were retrospectively analyzed. The clinicopathologic features of sebaceoma were investigated. Results There were 9 males and 22 females. The patients′ age was 53.90 ± 15.40 years, and the clinical course was 9.41 ± 13.75 years. Sebaceoma predominantly affected the face. The common lesion of sebaceoma was red, yellowish?red, skin?colored or slight brown papules, with no subjective symptoms in most cases. Histopathologically, neoplasms had symmetric structures, and were located in the dermis. Epidermal involvements were found in 9 cases. The neoplasm cells were mainly composed of basaloid cells, a few mature sebocytes and some transition cells. The proportion of mature sebocyts was less than 1%in 26 cases, less than 20%in 2 cases, and 20%-40%in 3 cases. Mitoses were occasionally found in 5 cases. One patient was complicated by eccrine poroma. Varying amounts of ducts were found in all the patients. Immunohistochemical staining showed that epithelial membrane antigen was expressed on ducts and mature sebocytes in all the patients, while epithelial antigen was undetected in any of the patients. Carcinoembryonic antigen, androgen receptor and D2?40 were found in 20, 24 and 28 patients with sebaceoma, respectively. Conclusions The diagnosis of sebaceoma mainly depends on histopathological examination. Combined immunohistochemical detection of epithelial membrane antigen, androgen receptor and D2?40 is beneficial to its differential diagnosis.

The aims of this research were to construct prokaryotic expression vector containing the gene of porcine urate oxidase (pUOX), optimize the conditions of the expression of pUOX in recombinant Escherichia coli BL21(DE3), and analyze the in vitro activity and the enzymological properties of pUOX. The pUOX gene was amplified by RT-PCR from the extracted total RNA of porcine liver, and was inserted into the prokaryotic expression vector pET30a(+) to construct a recombinant expression vector pET30a(+)/pUOX. We identified the recombinant vector by endonuclease digestion and sequence analysis. The pUOX gene was amplified and cloned into the vector pET30a(+) successfully. And then the recombinant vector was transformed into E. coli BL21(DE3). The expression of pUOX with a molecular of approximately 41 kD was induced by IPTG. We also optimized the expression conditions of the recombinant protein. The recombinant protein was mostly located in the cytoplasm and it was insoluble. After the inclusion body was solved in 8 mol/L urea and refolding in 2 mol/L urea, the recombinant protein was collected and purified by Ni2+-NTA column. This recombinant protein had a specific activity of 50.61 IU/mg and showed similar properties of optimum temperature and thermal stability, base on the enzymatic assay and analysis of enzymological properties. These results would help to analyze the in vivo activity by testing animal.

Gliomas are extremely aggressive brain tumors with a very poor prognosis. One of the more promising strategies for the treatment of human gliomas is targeted immunotherapy where antigens that are unique to the tumors are exploited to generate vaccines. The approach, however, is complicated by the fact that human gliomas escape immune surveillance by creating an immune suppressed microenvironment. In order to oppose the glioma imposed immune suppression, molecules and pathways involved in immune cell maturation, expansion, and migration are under intensive clinical investigation as adjuvant therapy. Toll-like receptors (TLRs) mediate many of these functions in immune cell types, and TLR agonists, thus, are currently primary candidate molecules to be used as important adjuvants in a variety of cancers. In animal models for glioma, TLR agonists have exhibited antitumor properties by facilitating antigen presentation and stimulating innate and adaptive immunity. In clinical trials, several TLR agonists have achieved survival benefit, and many more trials are recruiting or ongoing. However, a second complicating factor is that TLRs are also expressed on cancer cells where they can participate instead in a variety of tumor promoting activities including cell growth, proliferation, invasion, migration, and even stem cell maintenance. TLR agonists can, therefore, possibly play dual roles in tumor biology. Here, how TLRs and TLR agonists function in glioma biology and in anti-glioma therapies is summarized in an effort to provide a current picture of the sophisticated relationship of glioma with the immune system and the implications for immunotherapy.

Objective:To investigate the value of machine learning-based computed tomography (CT) images radiomics analysis in preoperative evaluation of surgical portal vein-superior mesenteric vein (PV-SMV) invasion in patients with pancreatic ductal adenocarcinoma (PDAC).Methods:The retrospective study was conducted with 156 consecutive PDAC patients who were underwent surgery at the Affiliated Wuxi No.2 People's Hospital of Nanjing Medical University between January 2010 and July 2021. There were 95 males and 61 females, with the age of (65.7±8.2) years. Patients were randomly split into training set and validation set by a ratio of 3∶2. Minimum redundancy maximum relevance was used to select radiomic features, which were extracted from contrast-enhanced CT images. Five machine learning classifiers were developed, and those models' area under the curve (AUC) values were compared with the conventional radiologic-feature-based evaluation.Results:Ninety-four and 52 patients were included into the training set and validation set, respectively. Their PV-SMV invasion rates were confirmed by intraoperative exploration with 31.9%(30/94) and 40.3%(25/61), respectively. Five models: LASSO regression, random forest, support vector machine, k-nearest neighbor and Naive Bayesian, were established based on ten features from CT images radiomics, and LASSO regression model achieved the highest AUC value compared with the other four models (all P<0.05). Compared with the conventional radiologic evaluation, the LASSO regression model had higher AUC (0.920 vs. 0.752) and sensitivity (92.0% vs. 86.5%)(both P<0.05). Conclusion:Machine learning-based CT images radiomics analysis can be used to evaluate PV-SMV invasion status preoperatively in PDAC. The LASSO regression model showed better performance than the conventional radiologic evaluation.
