Objective To evaluate the effects of 'patch-skill'in the management of refractory bleeding during the process of open heart surgery.Methods Between May 2007 to Oetober 2008,7 patients undergoing open-heart surgery experienced active bleeding.Autologous perieardial patches were used in 6 patients, and polyester patch in the other one.The patches were sutured continuously by 5-0 Prolene suture.Results The 24 hour chest tube output was less than 500 ml in all 7 cases after operation.There were no death, secondly active bleeding,or mediastinal in-faction.Conclusion The'patch-skill' can effectively control the refractory bleeding during open heart surgery.Au-tologous perieardial patehe is the first choice because it has multiple advantages.The polyester patch ean be used al-ternatively when autologous pereardiurn cannot be used (for various reasons such as edema and infection).

OBJECTIVETo study on academic point of view of the book, A General Survey of Moribustion.

METHODSStudy academic thought of the book and clarify academic origin and characteristics of the book.

CONCLUSIONProcessing of argyi leaf, manufacture of mugwort floss and size of moxa cone have a certain technique standards in the book. The book indicates that small cones should be used with more times of moxibustion. and the properties of mugwort floss are not dry and heat, but are warm and moist and mild, moxibustion not only can be used to treat cold syndrome but also can be used to treat heat syndrome; the body can response to the external moxibustion. The above points of view have still guiding significance in nowadays.

OBJECTIVETo study the effects of rhizoma sparganii and radices zedoariae on hepatic fibrosis.

METHODThe rat immunohepatic fibrosis model was made by intraperitoneal injection of porcine serum and treated with rhizoma sparganii and radices zedoariae. The ALT, GGT, TP, ALb, A/G, IVC, LN, HA and the pathological change of the liver were observed.

RESULTRhizoma sparganii and radices zedoariae could increase TP, ALb, A/G, decrease ALT, GGT, IVC, LN, HA and improve the pathological change.

CONCLUSIONRhizoma sparganii and radices zedoariae can protect hepatic cells, alleviate degeneration and necrosis, recover structure and function, and reduce the proliferation of fibrous tissue.

OBJECTIVEThe study was designed to investigate the expression patterns of metalloproteinase (MMP)-13 protein in invasive breast carcinoma and to determine the clinicopathological and prognostic values of its various localization and relation to the tumor phenotypes.

METHODSImmunohistochemistry was performed on paraffin-embedded tissue array from 263 invasive breast carcinomas to investigate the protein expressions of MMP-13, estrogen receptor, progesterone receptor, HER2, MMP-2, MMP-9 and tissue inhibitor of matrix metalloproteinases (TIMP)-1, TIMP-2.

RESULTSMMP-13 protein was detected in the cytoplasm of carcinoma cells and peritumoral fibroblasts. High level expression of MMP-13 protein in tumor cells was associated with more lymph node involvement and higher tumor grade (both P < 0.01), and positively correlated with HER2 (P = 0.015) and TIMP-1 protein (P < 0.01) expression in carcinoma cells. Moreover, high expression of MMP-13 was associated with shortened overall survival for the entire patient population and the patient group with positive lymph node. Tumor cell derived MMP-13 had different impact on patients with different HER2 status. Peritumoral fibroblasts derived MMP-13 protein, although correlated with tumor cell derived MMP-13 and associated with lymph node stage and HER2 expression, was found having less prognostic impact. Univariate survival analysis showed that the tumor size, grade, lymph node status, PR status, HER2 expression, tumors TIMP-1 and MMP-13 expression were prognostic factors. However, multivariate survival analysis showed that only tumor size, lymph node status, HER2 expression, tumors TIMP-1 and MMP-13 were independent prognostic factors.

CONCLUSIONMMP-13 protein expressed by tumor cells correlates with the invasion and metastasis of breast carcinoma, and therefore, may serve as a poor prognostic marker for the patient.

Chinese medicine processing is a kind of traditional pharmaceutical technology,which can reduce toxicity,enhance the curative effect,change the properties and facilitate dispensing preparations in clinical use.The technology of detoxification is a great pioneering work for the safe application of toxic Chinese medicine,which can reduce the side effects of certain drugs,ensure the clinical safe use and expand the scope of clinical application through processing.In this paper,we searched the toxic Chinese medicine and the processing technology in ancient literatures of TCM,and then we summarized and analyzed their lat-est studies at home and abroad.Thus,we make a summary of toxic Chinese medicine including its classification,site of action,the toxic components,detoxification and its clinical application.Meanwhile,we proposed an opinion that toxic Chinese medi-cines with the same processing technology had common detoxification rules.Therefore,we hope this work will provide new perspectives for the research on the processing of toxic Chinese medicine and the mechanism of detoxification.

BACKGROUNDObstructive sleep apnea (OSA) syndrome has a negative impact on the health of millions of adolescents and youth. The aim of this study was to evaluate the associations of OSA syndrome with obesity and cardiometabolic risk factors among adolescents and youth at risk for metabolic syndrome (MS).

METHODSA total of 558 subjects aged 14-28 years were recruited from the Beijing Child and Adolescent Metabolic Syndrome Study. Each underwent a 2-h oral glucose tolerance test (OGTT), echocardiography, and liver ultrasonography. Anthropometric measures, blood levels of glucose, lipids, and liver enzymes were assessed. Subjects with high or low risk for OSA were identified by Berlin Questionnaire (BQ).

RESULTSAmong the subjects in obesity, 33.7% of whom were likely to have OSA by BQ. Subjects with high risk for OSA had higher neck and waist circumference and fat mass percentage compared to those with low risk for OSA (P < 0.001). Moreover, significant differences in levels of lipids, glucose after OGTT, and liver enzymes, as well as echocardiographic parameters were found between the two groups with high or low risk for OSA (P < 0.05). The rates of nonalcoholic fatty liver disease (71.0% vs. 24.2%), MS (38.9% vs. 7.0%), and its components in high-risk group were significantly higher than in low-risk group.

CONCLUSIONSThe prevalence of OSA by BQ was high in obese adolescents and youth. A high risk for OSA indicates a high cardiometabolic risk. Mechanisms mediating the observed associations require further investigation.

OBJECTIVETo investigate the proper time of cryo-preserving tracheal allograft so as to minimize its antigenicity.

METHODSOn a dog model, this study was carried out by allografting a tracheal into a muscular flap formed with sternocephalic muscle and sternohyoid--sternothyroid muscle. The tracheal was treated with cryopreservation in defferent intervals. The viability of the graft was evaluated by the examination of fiberoptic bronchoscopy, histopathology and microangiography. The blood flow of the tracheal mucous was measured with a blood flowmeter and the survival area was decided in the calculation of the percentage.

RESULTSThere are no significant differences in the mucous membrane appearance and the mucosal blood flow one week after the surgery among the non-cryopreservation group and the groups treated with cryopreservation in 1 day, 2 weeks, 4 weeks, 6 weeks and 8 weeks. The graft was found to start necrosis 2 weeks after the transplantation with the infiltration of mononuclear cells examined under light microscope in almost all of the groups, especially in the non-cryopreservation group and the groups treated with cryopreservation in 1 day, 2 weeks. However, there was no significant difference among the autograft group and the allograft groups cryopreservated in 6 weeks and 8 weeks, and the infiltration of the mononuclear cells was not found in these groups either.

CONCLUSIONThe antigenicity of the tracheal allografts could be significantly decreased by the treatment of cryopreservation over 6 weeks.
