Resource Value Discovery and Utilization of Wastes in Industrialization of Rhei Radix et Rhizoma / 中国实验方剂学杂志

The recycling of traditional Chinese medicine （TCM） wastes is an important research topic to be solved urgently in the industrialization of TCM resources. Rhei Radix et Rhizoma is a bulk Chinese herb mainly derived from Rheum palmatum，R. tanguticum，and R. officinale. At present，these three medicinal plants have been cultivated on a large scale and widely used in the fields of medicine，health care，food，cosmetics，and veterinary medicine，with an annual demand of more than 5 500 tons（1 ton=1 000 kg）. However，a large number of wastes such as non-medicinal parts and residues produced in the production and deep processing are discarded because there is no effective way of utilization，resulting in serious waste of resources and environmental pollution. The non-medicinal parts contain not only the chemical components and pharmacological effects similar to those of roots and rhizomes but also a variety of amino acids，mineral elements，and conventional nutrients. They have a long history of use，and the content of some resource components is higher than that in roots and rhizomes. In particular，their stems and leaves exhibit great potential to be consumed as food and medicine due to high safety. Besides，the content of anthraquinones in Rhei Radix et Rhizoma residue is high and it possesses good antibacterial activity. It can be seen that the waste from the industrialization of Rhei Radix et Rhizoma has high utilization value. Hence，based on the relevant literature and investigation on the application of producing areas in China and abroad，the paper summarized the utilization status of their medicinal and non-medicinal parts，the waste production in the industrialization，as well as the active substances and utilization ways and put forward the multi-level and multi-path utilization strategy of Rhei Radix et Rhizoma wastes，in order to provide reference for the rational development and application of Rhei Radix et Rhizoma resources and promote the effective utilization and green development of the corresponding wastes.

Network pharmacology unveils spleen-fortifying effect of Codonopsis Radix on different gastric diseases based on theory of “same treatment for different diseases” in traditional Chinese medicine / 中草药·英文版

Objective: “Same treatment for different diseases” is a unique treatment strategy under the guidance of traditional Chinese medicine (TCM) theory. Codonopsis Radix (Codonopsis pilosula, Dangshen in Chinese) with spleen-fortifying effect was employed to understand the strategy of “Same treatment for different diseases”, based on its common mechanism in the treatment of gastric diseases including gastric ulcer, gastritis and gastric cancer via network pharmacology research. Methods: Network pharmacology research methods were used to analyze the interaction network and potential mechanisms of Dangshen in treating gastric ulcer, gastritis and gastric cancer. The active components and their target proteins of Dangshen were integrated from TCMSP, BATMAN-TCM databases. The targets of gastric ulcer, gastritis and gastric cancer were collected through GeneCards, PubMed, TDD and DisGeNET Database. Through screening, the key components and the key targets of Dangshen in treating gastric ulcer, gastritis and gastric cancer were obtained. After KEGG pathway analysis and GO analysis, the important pathways and biological processes were analyzed. Results: Through data and literature mining, the common and specific pharmaceutical effects and mechanism of Dangshen were summarized in these three gastric lesions. It was shown that Dangshen mainly acted on gastric ulcer, gastritis and gastric cancer through the overall regulation of the PI3K-AKT signaling pathway. With the development of the disease, it will gradually increase the control of inflammation through TNF, NF-κB and other inflammation-related signaling pathways to reduce inflammatory damage. For tumorigenesis, it pays more attention to inhibiting the ErbB signaling pathways to reduce the proliferation and migration of tumor cells. In addition, Dangshen's regulation of HIF-1 signaling pathway may also be beneficial for the treatment of gastric ulcer, gastritis and gastric cancer. Conclusion: Dangshen achieves spleen-fortifying effect on gastric diseases including gastric ulcer, gastritis and gastric cancer through multiple targets in multiple pathways, especially PI3K-AKT pathway and HIF-1 pathway. It could provide a scientific basis for understanding the strategy of “Same treatment for different diseases” in traditional Chinese medicine.

Fine needle aspiration cytology diagnosis of ductal lesions of breast / 中华病理学杂志

<p><b>OBJECTIVE</b>To find out the most effective and combined cytomorphologic criteria trying to set up an effective diagnostic model for breast ductal lesion in fine needle aspiration cytology (FNAC).</p><p><b>METHODS</b>A total of 400 breast FNAC cases were collected with follow-up information of more than six years. A retrospective analysis including 104 non-proliferative breast diseases, 163 proliferative breast diseases and 133 carcinomas basing on the diagnostic results of surgical biopsies. Altogether, 60 cytomorphologic variables were counted for the evaluation of each case, including 4 main categories: the cellularity and components, natures of background, cellular arrangements and the cellular features. According to the quantity or the classification stage, the variables were semi-quantitatively scored. Multiple step-wise logistic regression (SPSS) and classification tree model (SAS) were performed to determine the significant and combined variables predictive for the diagnosis of non-proliferative lesion, proliferative breast diseases and carcinoma, respectively.</p><p><b>RESULTS</b>(1) Among 400 benign and malignant cases studied, and basing on the result of analyses of multiple step-wise logistic regression system, intermingling of myoepithelial cells within the epithelial cluster (P < 0.05), presence of large epithelial cell cluster (P < 0.05), presence of small epithelial cell cluster (P < 0.05), cytoplasmic vacuoles (P < 0.05) and figures of "progressive intussusception" of cells (P < 0.1) were selected as the effectively differential diagnostic criteria for the benign and malignant lesions. However, according to the classification tree model, the most useful variable selected associating with the benign lesion was intermingling of myoepithelial cells within epithelial cluster. The diagnostic accuracy will be increased to 94.4%, if another criterion, presence of a big amount of large epithelial clusters, was used as the second useful variable in combination. Presence of a moderate to large amount of small epithelial cell clusters were indicative of proliferative lesion. If the criterion of myoepithelial cells intermingling within epithelial cluster was not found in the sample and associating with presence of small epithelial cell clusters, cytoplasmic vacuoles and figures of "progressive intussusception" of cells, mostly (81.3%), it would be considered as a case of carcinoma. (2) Among 267 benign non-proliferative and proliferative breast diseases studied, both the multiple step-wise logistic regression and classification tree model, presence of irregular intercellular spaces within the epithelial clusters (P = 0.001), loose epithelial clusters (P < 0.05) and hyperchromasia (P < 0.1) were selected as the significant differential diagnostic criteria for the proliferative lesion. The architectural variables and the amount of the abnormal cell features such as cell cluster formation were considered to be more important. A high frequency of presence of irregular intercellular spaces within the epithelial clusters and the amount of loose epithelial clusters indicated a higher possibility of a proliferative lesion. Presence of a single variable of irregular intercellular spaces within the epithelial clusters had the possibility of a benign lesion diagnosis up to 70.1% in all the proliferative breast disease cases collected in this series. If the frequency of irregular intercellular spaces increased to a moderate degree or even higher, the possibility of a benign lesion would be increased to 82.7%. The possibility of a proliferative breast disease would be reached to 87.5%, if both the criteria of irregular intercellular spaces and loosely arranged epithelial cell clusters were counted in combination. (3) The histological results of 35 lesions with atypical cytological features in FNAC specimens were predominantly a proliferative lesion of the breast (26 cases), and most of them were fibroadenoma with ductal hyperplasia. Occasionally, there might be a few benign cases complicating with lesions of atypical hyperplasia or carcinoma.</p><p><b>CONCLUSIONS</b>In breast FNAC diagnosis, a combined evaluation of significant variables and the amount of the variable involved are effective for the differential diagnosis between benign/malignant and non-proliferative/proliferative lesions. Lesion accompanying with atypical cellular features should avoid to be overdiagnosed as carcinoma, and biopsy for a histological diagnosis is indicative.</p>

Fine needle aspiration cytology of myxoid lesions of soft tissues: a study of 24 cases / 中华病理学杂志

<p><b>OBJECTIVE</b>To summarize the diagnostic features of fine needle aspiration cytology (FNAC) of myxoid lesions in soft tissue, and to define the cytological criteria for differentiating benign lesions from sarcomas and between various myxoid lesions.</p><p><b>METHODS</b>FNAC data of 24 soft tissue myxoid lesions (14 benign lesions, 10 malignant lesions) from 1993 to 2006 from Kiang Wu Hospital, Macau were reviewed in correlation with the clinical course or the results of biopsy.</p><p><b>RESULTS</b>Ganglion, myxoma, and myxoid nodular fasciitis were the most common benign myxoid lesions of the soft tissues, all of which had low cellularity and lack of marked cellular atypia in smears in common. Ganglion was characterized by the disappearance of or the gradual minimization of the nodule after aspiration and the lack of blood vessel in smears. Myxoid nodular fasciitis was characterized by a pleomorphic pattern of proliferative cells and the presence of ganglion cell-like cells. Myxoid liposarcoma, extraskeletal myxoid chondrosarcoma and myxofibrosarcoma were the most common myxoid sarcomas. Cytologically, they had high cellularity and various degrees of cellular atypia. Myxoid liposarcoma exhibited branching chicken-wire like capillary vessels and/or lipoblasts; myxofibrosarcoma were prominent in both pleomorphic and atypia of the cells. The data revealed that the diagnostic accuracy of FNAC was nearly 100% in differentiating benign and malignant myxoid lesions of the soft tissues. The coordinate rate to the histopathology diagnosis of the common myxoid lesions of the soft tissues was above 75% (benign 71.4% and malignancy 80% respectively).</p><p><b>CONCLUSIONS</b>FNAC is an effective method in diagnosing myxoid lesions of soft tissue, in correlation with the clinical data and the accessory examinations. FNAC can provide an objective basis for the treatment of myxoid lesions and prevention of unnecessary surgical operations.</p>

The effect of p38 on the cycloheximide-induced HL-60 cell death through mitochondria pathway / 中华血液学杂志

<p><b>OBJECTIVE</b>To study the effect of p38 on the cycloheximide (CHX)-induced HL-60 cell death through mitochondria pathway.</p><p><b>METHODS</b>Inhibition of p38 pathway was by SB203580 (SB). Four groups were set up: control, SB only, CHX only and SB + CHX. Sub-diploid cell ratio was detected by PI staining flow cytometry at 6, 9, 12, 18, 24 h time points, and apoptotic cell ratio by Annexin V-FITC/PI double staining flow cytometry at 6 h and 18 h time points. High J-aggregate cells were evaluated by the J-aggregate contents, measurement of the J-aggregate (FL2) and J-monomer (FL1) by JC-1 flow cytometry, calculation of the delta psi m by FL2/FL1 and analysis of the delta psi m changes at 18 h time points.</p><p><b>RESULTS</b>The sub-diploid cell ratio in CHX group was significantly higher than that in control group at 6 h time point, and the ratio in SB + CHX group was significantly higher than that in CHX group at 9 h time point. At 18 h time point the apoptotic cell ratios in both CHX and SB + CHX groups were significantly higher than those in control group (P < 0.01). There was no significant difference of apoptotic cell ratio between CHX group and SB + CHX group (P > 0.05). At 18 h time point the necrotic cell ratios in both CHX and SB + CHX groups were significantly higher than that in control group (P < 0.01); and that in SB + CHX group was significantly higher than that in CHX group (P < 0.01). The high J-aggregate cell ratios in CHX and SB + CHX groups were significantly lower than that in control group (P < 0.05), and that was signficantly lower in SB + CHX group than in CHX group (P < 0.01). For the FL2/FL1 value (delta psi m) CHX group (0.17 +/- 0.01) and SB + CHX group (0.05 +/- 0.003) were significantly higher than control group (0.38 +/- 0.02) (P < 0.01), and SB + CHX group was significantly lower than CHX group (P < 0.01).</p><p><b>CONCLUSION</b>CHX can induce HL-60 cell apoptosis and the cell mitochondria depolarization, and the latter was intensified by inhibition of the p38 pathway. p38 pathway may related to the cell necrosis in the cycloheximide-induced HL-60 cell apoptosis model. s</p>

Role of immunocytochemistry in fine needle aspiration cytology diagnosis of mammary lesions of breast / 中华病理学杂志

<p><b>OBJECTIVE</b>To study the value of immunocytochemical study for cyclin D1, c-erbB-2, Ki-67, p21(CIP1/WAF1) and 34betaE12 in fine needle aspiration cytology (FNAC) diagnosis of mammary lesions.</p><p><b>METHODS</b>One hundred and thirty-five cases of breast diseases, all with FNAC performed and follow-up histologic correlation available, were enrolled into the study. These included 43 cases of benign non-proliferative diseases, 45 cases of benign proliferative diseases and 47 cases of mammary carcinoma. Immunostaining for cyclin D1, c-erbB-2, Ki-67, p21(CIP1/WAF1) and 34betaE12 was carried out on FNAC smears and paraffin sections of the corresponding biopsy specimens. The statistical significance was analyzed using SPSS11.5 software.</p><p><b>RESULTS</b>No statistically significant difference was observed in the expression of cyclin D1, c-erbB-2, Ki-67, p21(CIP1/WAF1) and 34betaE12 within the groups of benign non-proliferative and benign proliferative breast diseases. On the other hand, a significant difference in immunostaining results was found between benign breast lesions and mammary carcinoma (P < 0.001). A panel of cyclin D1, 34betaE12 and c-erbB-2 immunostaining is highly sensitive and specific in confirming the diagnosis of mammary carcinoma in FNAC samples. A positive reaction for cyclin D1 and c-erbB-2, when coupled with a negative reaction for 34betaE12, showed to be the most reliable supportive evidence for the malignant cytologic diagnosis. When taking the results of either cyclin D1 or 34betaE12 immunostaining into consideration, the sensitivity and specificity for diagnosing carcinoma was 95.7% and 94.3% respectively. On the other hand, when any of the three immunostains suggested carcinoma, the diagnostic sensitivity and specificity became 97.9% and 92.0% respectively. If the immunostaining results of any two of the three markers suggested carcinoma, the diagnostic sensitivity and specificity became 72.3% and 100% respectively. Within the carcinoma group, the degree of expression of cyclin D1, p21(CIP1/WAF1) and 34betaE12 showed little difference amongst different cytologic grades (according to Robinson cytologic grading system). There were however differences in expression of c-erbB-2 and Ki-67. Highest expression rate was observed in grade 3 carcinoma, while lowest expression rate was observed in grade 1 carcinoma (only in 40.0% and 33.3% of cases respectively). Whenever either cyclin D1 positivity or 34betaE12 negativity was demonstrated, the diagnostic accuracy for grade 1 and grade 2 carcinoma was 93.3% and 96.2 % respectively.</p><p><b>CONCLUSIONS</b>Immunocytochemical study using a panel of antibodies for cyclin D1, c-erbB-2, and 34betaE12 has significant diagnostic value in distinguishing between benign breast diseases and mammary carcinoma in FNAC samples. Cyclin D1 and 34betaE12 are especially useful in confirming the cytologic diagnosis of low-grade cancer.</p>

Examination expression of CD3 and CD69 in nasal polyps / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the infiltration of T lymphocytes with CD3 expression as surface marker and the activation of T lymphocytes with CD69 expression as activation marker.</p><p><b>METHODS</b>Nasal polyp tissue samples and peripheral blood were obtained from 21 patients. The normal inferior turbinate mucosa and peripheral blood were obtained as comparison. Flow cytometry was adopted to detect the expression of CD3 and CD69 of T lymphocytes.</p><p><b>RESULTS</b>Nasal polyp tissue consisted of abundant T lymphocytes. Activation marker CD69 was expressed in T lymphocytes of nasal polyps (36.96 +/- 2.50)% and peripheral blood (4.66 +/- 0.18)% from the same patient. The expression rates of CD69 after a short-term stimulation (5 h) in response to PDB were (59.88 +/- 2.59)% and (92.76 +/- 0.55)% respectively. While T lymphocytes was rarely detected in normal inferior turbinate and the expression of CD69 was low in peripheral blood from normal human but almost all T lymphocytes were activated after stimulation.</p><p><b>CONCLUSIONS</b>There were generous of T lymphocytes infiltrating in nasal polyps. The expression of CD69 in T lymphocytes was abnormally high, which indicated that T lymphocytes infiltrating in nasal polyps were in activated state immunologically.</p>

Celecoxib Inhibits Proliferation and Induces Apoptosis via Cyclooxygen-ase-2 Pathway in Human Pancreatic Carcinoma Cells / 华中科技大学学报（医学）（英德文版）

In order to evaluate the effects and mechanisms of celecoxib in inhibiting proliferation and inducing apoptosis on human pancreatic carcinoma cells, the anti-proliferative effect was measured by using methabenzthiazuron (MTT) assay. Cell cycle and apoptosis were analyzed by using flow cytometry (FCM), and the PGE2 levels in the supernatant of cultured pancreatic carcinoma cells were quantitated by enzyme-linked immunoabsordent assay (ELISA). Our results showed that celecoxib suppressed the production of PGE2 and inhibited the growth of JF-305 cells, and the anti-proliferative effect of celecoxib could be abolished by addition of PGE2. FCM revealed that celecoxib could inhibit proliferation and induce apoptosis by G1-S cell cycle arrest. It was concluded that cyclooxygenase-2 specific inhibitor celecoxib could inhibit proliferation and induced apoptosis of human pancreatic carcinoma cells via suppression of PGE2 production in vitro.

The diagnostic value of 34 betaE 12 in differential diagnosis of benign and malignant mammary lesions / 中华病理学杂志

<p><b>OBJECTIVE</b>To determine the differential diagnostic value of high molecular cytokeratin 34betaE12 as a benign marker in mammary lesions.</p><p><b>METHODS</b>90 cases (30 benign non-proliferative diseases, 20 benign proliferative diseases, 10 intraductal carcinomas and 30 invasive carcinomas) were collected, all of which had undergone fine needle aspiration cytology (FNAC) examination and a follow-up operation. Immunohistochemical staining was performed using monoclonal antibodies against 34betaE12 on FNAC smears and the follow-up paraffin sections. SPSS 10.0 software was applied to analyze the differential diagnostic value of 34betaE12 in benign and malignant mammary lesions.</p><p><b>RESULTS</b>(1) No significant difference was found in the expression of 34betaE12 between benign non-proliferative and proliferative disease. (2) A significant difference was found between the expression of 34betaE12 in mammary benign disease and mammary carcinoma. 66.7% and 66.3% of the carcinoma cases showed either lack of 34betaE12 expression or had only a few isolated 1+ cells which were cytoplasmic positive for 34betaE12 immunoreaction on FNAC smear and paraffin section respectively. The remaining 33% of cases having 2+ to 3+ cells mainly displayed cytoplasmic granular positive reaction rather than strong membranous and cytoplasmic positive reaction as benign lesions. In contrast with carcinoma, most benign lesions showed strong immunoreaction of 2+ to 3+ and especially exhibited complete strong membranous and cytoplasmic positive reaction on paraffin section, their positive expressive character differed from those of carcinoma. The positive rates on FNAC smear and paraffin section were 100% and 78% respectively. (3) Certain types of intraductal carcinoma, including low grade cribriform, papillary and solid type either lacked 34betaE12 expression or revealed a few isolated 1+ cells with cytoplasmic positivity for 34betaE12 immunoreaction. Pronounced immunoreaction of 3+ was only seen in high grade comedotype intraductal carcinoma.</p><p><b>CONCLUSIONS</b>34betaE12 may serve as a marker of benign mammary disease for differential diagnosis. When there is a total or predominant lack of 34betaE12 expression, the possibility of carcinoma should be strongly considered. If 34betaE12 is expressed diffusely in the suspicious area with a strong membranous staining in particular, a benign proliferative process rather than carcinoma must be considered.</p>
