Concealed penis is usually found in children, which affects the patients both physiologically and psychologically. Some of the patients are wrongly treated by circumcision, which may bring about serious consequences to the sexual life of the patients in their adulthood. In the recent years, this disease has been receiving more and more attention from both doctors and parents. However, controversies remain as to its classification, pathogenesis, pathology, and treatment. This paper focuses on the understanding and advances in the studies of concealed penis.

ObjectiveTo evaluate the antitumor effects of lymphocytes from hepatic porta lymph node co cultured with staphylococcal enterotoxin A(SEA)?MethodsLymphocytes isolated from lymph node of 5 HCC patients were co cultured with SEA. The proliferation and cytotoxicity of the lymphocytes were observed. Flow cytometer was used to detect the expression of CD3?CD4 and CD8 on the surface of the lymphocytes. TNF ? and IFN ? released into the culture medium were measured by the method of ELISA. The results were compared with that yielded from TILs of the individual patients. ResultsCultured in the presence of SEA, there was a sharp rise of T cells, especially CD8 + cells. Cytotoxic activity was increased. TNF ? and IFN ? were predominantly produced in the first week.ConclusionsLymphocytes from lymph node activated by SEA were armed with an increased antitumor efficacy.

In this paper, we described basic connotations of comparative effectiveness research (CER), expounded the application of CER in chronic obstructive pulmonary disease (COPD). In addition, on the basis of research practice of Chinese medical treatment for COPD in recent years, we put forward the thought of the junction point of Chinese medicine in CER on COPD from the perspective in screening effective Chinese herbs, establishing treatment program/methods/technologies, and outcomes evaluation.

Objective To screen the Doc 1R gene recombinant plasmid by use of colony PCR. Method The recombinant colonies were transfered into the PCR reaction mixture. The PCR primers were used for constructing mouse Doc 1R genomic sequence. Result Among the 5, 3 positive strips in the size of 1 500 bp were visible, which were the same as the Doc 1R gene fractions in terms of their sizes were screened as positive clones. The positive colony were further confirmed by double digestion and DNA sequencing. Conclusion Colony PCR is a simple, efficient and reliable technique for screening the recombinant.

Objective To analyze mutations of the STAT3 gene in a patient with hyper-IgE syndrome (HIES).Methods Clinical data were collected and blood samples were obtained from a 14-year-old patient with hyper-IgE syndrome (HIES) and her parents.Genomic DNA was extracted and subjected to PCR for the amplification of the entire encoding and splice sites of the STAT3 gene followed by bidirectional sequencing.Meanwhile,amplified ribosomal DNA restriction analysis was carried out.Results A heterozygous missense mutation A1843G,which caused a K615E substitution,was found in exon 19 encoding the SH2 domain of the STAT3 gene in the patient,but not in either of her parents.The result of amplified ribosomal DNA restriction analysis was consistent with the findings mentioned above.Conclusion The novel K615E missense mutation in the STAT3 gene may contribute to the development of HIES.
