Objective To analyze the TCM principles of herbal prescriptions given by professor Zhang Shishun for esophageal cancer by using traditional Chinese medicine inheritance support system (V2.0). Methods The herbal prescriptions from professor Zhang were collected and used for esophageal cancer, and then were recorded into the traditional Chinese medicine inheritance support system. The date mining methods were used such as principle analysis and revised mutual information. Results A total of 166 prescriptions for esophageal cancer were collected, which involved 316 Chinese medicines. The medicines with high frequency were Ganoderma, Caulis Marsdeniae Tenacissimae, Fructus Trichosanthis, Herba Rabdosiae Rubescentis, and Agaricus Blazei Murrill. The combinations of medicines included Ganoderma and Ramulus Juglandis, Radix et Rhizoma Sophorae Tonkinensis and Caulis Marsdeniae Tenacissimae, and Herba Rabdosiae Rubescentis and Caulis Marsdeniae Tenacissimae. The prescription rules of drug combination mode were obtained. Conclusions The Professor Zhang advocated the theory of determination of treatment based on pathogenesis through differentiation of symptoms and signs, patho-examination, patho-location. He also stressed on the therapy of relieving both primary and secondary symptoms. The Ganoderma, Ramulus Juglandis and Agaricus Blazei Murril were used to strengthen the body resistance. Radix et Rhizoma Sophorae Tonkinensis, Caulis Marsdeniae Tenacissimae and Herba Rabdosiae Rubescentis were used to eliminate pathogenesis. The Endothelium Corneum Gigeriae Galli, Fructus Crataegi Praeparata, Massa Medicata Fermentata Praeparata were used to protect stomach-qi. The Fructus Trichosanthis, Bulbus Allii Macrostemonis and Folium Ginkgo wereused to dilate the esophagus. The Fructus Trichosanthis was often combined with Radix Scutellariae to serve all medicines on the esophagus.

Objective To explore the clinical, pathologic and immunohistochemical characteristics of gastrointestinal stromal tumor (GIST) and stromal tumor beyond the gastrointestinal tract. Methods Expression of CD117, CD34, SMA, Desmin and S-100 protein in 53GIST were detected using immunohistochemical S-P method, and then analyzed. Results Of 53 cases, 38 cases were detected as spindle type, 6 as epithelioid type and 9 as mixture type; 9 cases were benign,20 were borderline and 24 were malignant. Of the 9 benign cases, 8 originated in stomach, while only one originated in intestine and beyond the gastrointestinal tract. The rate of immunohistochemical expression was showed as follows: CD117 92.45% and CD34 77.36%. Conclusion GIST has its unique morphological characteristics. To detect CD117 and CD34 simultaneously may be helpful to the diagnosis. The malignant potential of stromal tumor in intestine and beyond the gastrointestinal tract is higher than that in stomach. The estimation of benignancy and malignancy depends on the site, the size and nuclei mitoses of the tumor.

Diabetes is a common clinical disease, with glucose and lipid metabolism disorder as the main clinical manifestation. The spleen of middle jiao can transport and transform the essence of grain and water. It is also the source of qi and blood, which also provides material foundation for the glucose and lipid metabolism. The spleen deficiency and dampness stasis can lead to the phlegm and blood stagnation, which are closely related to high sugar, high fat, high blood coagulation and vascular endothelial damage. This article discussed the relationship between the changes of spleen function of middle jiao and glucose and lipid metabolism, and provided some theoretical methods for clinical prevention and treatment of diabetes.

Objective To assess the reflectance confocal microscopic features of childhood lichen planus (LP),and to evaluate the performance of reflectance confocal microscopy (RCM) in the diagnosis of childhood LP.Methods RCM was performed for imaging of lesions in 35 children with LP.Then,biopsies were carried out at the same sites followed by histopathological examination.A comparison was conducted between confocal microscopic and histopathological findings.All the 35 cases were diagnosed based on clinical manifestations and histopathological findings.Results RCM imaging of lesions in the 35 cases showed cellular edema forming lowly reflective areas in the epidermis,sharp transition between the granular and spinous layers,and infiltration of moderately reflective inflammatory cells,which corresponded to wedge-shaped thickening of the granular layer on pathological examination.The dermo-epidermal junction was unclear,and dermal papillary rings were obscure or absent with infiltration of inflammatory cells arranged in lamelliform structures around the dermo-epidermal junction,which corresponded to interface dermatitis on histopathological examination.A band-like infiltration of inflammatory cells,including big,highly reflective oval or stelliform pigmentophages and small,moderately reflective round lymphocytes,was observed in the dermis,and the thickness of infiltration was measurable.Dilated blood vessels were longitudinally distributed in the papillary dermis with perivascular infiltration of inflammatory cells and pigmentophages.RCM images were highly consistent with histopathological findings in these patients.Conclusion RCM,as a real-time non-invasive imaging technique,can serve as an auxiliary examination method for the diagnosis of childhood LP.

Objective To determine the expression of macrophage migration inhibitory factor (MIF)in different molecular subtypes of breast cancer and its clinical significance so as to detect the biological markers of different molecular subtypes of breast cancer.Methods We divided 100 breast cancer patients into four molecular subtypes by immunostaining:luminal subtype,HER-2(+)subtype,basal-like (BLs)subtype and normal breast-like (NBLs)subtype,and then compared the expression of MIF in the groups.We analyzed the associations of MIF-positive expression rate with age,menstruation,tumor size,auxiliary lymph node metastasis,histological type and grade,and clinical stage of the breast cancer patients.We also compared MVD level and 5-year overall survival rate between MIF-positive patients and MIF-negative ones.Results The positive expression of MIF was correlated with HER2(+)subtype breast cancer and auxiliary lymph node metastasis (P < 0.05 ).The patients with MIF-positive expression had a significantly higher level of MVD than those with MIF-negative expression (P < 0.05 ). Kaplan-Meier method showed that MIF-positive patients had a poor prognosis than MIF-negative ones (Log-rank=1 9.5 1 6,P = 0.000).Conclusion Breast cancer patients with MIF-positive expression may be mostly of HER2 (+)subtype,and tend to develop auxiliary lymph node metastasis.These patients have a significantly higher level of MVD and poor prognosis than those with MIF-negative expression.
