This article briefly discussed the academic thoughts and clinical experience of Professor WANG Yan-gang in treating the stomach cold from the theory of Zhuodu. According to the theory of Zhuodu, Professor WANG Yan-gang usesHuazhuo Jiedumethod to relieve or significantly ease the symptoms of stomach cold by exploring the reasons through syndrome differentiation and treatment based on reason.

Objective: To investigate the expressions of uPA (urokinase-type plasminogen activator) and PAI-1 (plasminogen activator inhibitor-1) in human breast cancer tissues and their clinical significance. Methods: The expressions of uPA and PAI-1 in breast cancer tissue samples from 252 patients with breast cancer were detected by immunohistochemistry. The associations between the expressions of uPA and PAI-1 with the clinicopathological factors were evaluated by using Kruskal-Wallis rank sum test. The correlation of uPA expression and PAI-1 expression was examined by using Spearman's rank correlation test. The survival analysis was conducted to assess the impacts of uPA and PAI-1 expressions on the prognosis of patients with breast cancer. Results: The expressions of uPA and PAI-1 were related to nuclear grade, tumor size, axillary lymph node status and Ki67 expression (P < 0.05), and the expression of uPA was also related to HER-2 (human epidermal growth factor receptor 2) expression (P < 0.05). In breast cancer tissues, the expressions of uPA and PAI-1 showed a positive relationship (rs = 0.773, P = 0.000). In subgroups of patients with lymph node-negative and lymph node-positive breast cancer, a positive relationship (rs = 0.760, P = 0.000; rs = 0.780, P = 0.000) was also seen between uPA and PAI-1 expressions. The tumor size (P = 0.023), nuclear grade (P = 0.008), axillary lymph node status (P = 0.000) and the expressions of HER-2 (P = 0.033), uPA (P = 0.005) and PAI-1 (P = 0.023) were associated with DFS (disease-free survival). Of these factors, axillary lymph node status was an independent prognostic factor for patients with breast cancer. The result of subgroup analysis revealed that the expressions of uPA and PAI-1 could influence the DFS of patients with lymph node-negative breast cancer (P = 0.000; P = 0.045). Conclusion: The results of this study suggest that uPA and PAI-1 may be used as prognostic markers and also be helpful to make treatment decisions, especially for patients with lymph node-negative breast cancer.

Objective:To promote the application of barcode technology and establish comprehensive barcode management platform for medical equipment in order to achieve precise management of medical equipment just like ID.Methods: Combined with information management of barcode was effectively applied to the medical equipment asset; analyzed the underlying application of barcode technology in the field of equipment asset management; finally, to clarify the application effect of barcode technology in precise equipment asset management.Results: The application of barcode technology has realized dynamic management for the whole life cycle of medical equipment, and effectively improved management method and efficiency of hospital medical equipment asset.Conclusion:Through informatization to support precise management for medical equipment, and this method can form more scientific and technological barcode technology management mode for medical equipment asset. This mode can reduce the workload and difficulty for routine equipment asset management, enhance the precise management level for equipment asset, and provide a powerful technical guarantee for the reasonable and effective integration of hospital equipment assets.

Objective: To search for new isoflavones with more potent antitumor activities from the target compounds synthesized by inserting a double bond or an acetylene bond between chromone and its 3-substituted phenyl, ester and hydroxymethyl groups, or by formation of an amide of 3′ or 4′-amino group of isoflavones with norcantharidin. Methods: The key intermediate 3-iodo-7-methoxyl-4H-chromen-4-one (5) was prepared with 2-hydroxyl-4-methoxyl- acetophenone and ethyl formate. The target compounds with 3-substituted double bond or acetylene groups were synthesized by Heck coupling and Sonogashira coupling reaction; the amide compounds were synthesized by Suzuki coupling reaction and amide formation of 3′ or 4′-amino group of isoflavones with norcantharidin. All of the target compounds were confirmed by 1HNMR, MS and IR spectra. The IC50 values of target compounds were determined by the standard method using two kinds of human tumor cell lines, colon cancer cell line HCT116 and liver cancer cell line SMMC 7721 to study their anti-tumor activities. Results: All the 17 target compounds obtained had certain anti-tumor effect in vitro, with compounds 7h and 7e showing better anti-tumor effects, which were similar to that of control curcumin and more potent than that of genistein in vitro. Conclusion: The insertion of a double bond or an acetylene bond between chromone and its 3-substituted phenyl, ester and hydroxymethyl groups may promote the anti-tumor activities of isoflavone analogues. It seems that the formation of an amide of 3′- or 4′-amino group of isoflavones with norcantharidin has no noticeable promotion effect on the anti-tumor activities.

Objective To study imaging features of primary chondrosarcomas and the correlation with pathologic basis.Methods The imaging materials of primary chondrosarcoma in 21 cases were retrospectively analyzed and correlated with pathological results. Results In 21 cases,the pathologic classifications were as following:15 cases of conventional intramedullary,1 case mesenchymal,2 cases myxoid,1 case dedifferentiated and 2 cases with no subtypes.For 6 cases of conventional intramedullary in gradeⅠand 8 cases in gradeⅡ,bone destruction in varying degrees accompanied with soft tissue mass(n=1 1),regional thickening cortical bone (n=2),“ring-arc”like matrix mineralization(n=6),amorphous (n=3)were showed on X-ray study.CT were performed,in 6 cases in gradeⅠ,6 cases in gradeⅡ and 1 case in grade Ⅲ in which there were intraosseous calcification (n=12),regional thickening cortical bone (n=2)and periosteal new bone formation (n=1).Lesions appeared expansive or osteolytic bone destruction accompanied with soft tissue mass on CT and MRI srudy MRI were performed in 5 cases in gradeⅠ and lesions were heterogeneous high signal intensity on T2 WI with spot like and “ring-arc”like low signal intensity.Conclusion Pathologic classifications and grading of primary chondrosarcoma may be presumed with imaging features.Pathologic characteristic manifestions on MR are superior to that on CT and X-ray.

As one of the major geriatric syndromes,frailty exerts adverse effects on life expectancy and quality of life of the elderly.Because of its importance,a number of methods and tools have been introduced for the assessment of frailty.Malnutrition,as an independent risk factor,interacts with frailty and is involved in its progression.This article reviews recent studies on frailty and malnutrition.
