Objective:To study the perioperative anticoagulant therapy for patients in prevention of moderate or high risk of pulmonary embolism(PE)after general surgery.Method:1146 patients who had undergone major general surgery were divided into a non-anticoagulant therapy group and an anticoagulant therapy group.There were 743 patients without the anticoagulant therapy during Jan.2005 to Aug.2008,a preventive anticoagulant therapy was performed on 403 patients who recived 5 000IU(142 patients at moderate risk of PE)or 10 000IU(261 patients at high risk of PE)low molecular weight heparin(LWMH)subcutaneous injection after major general surgery during Jan.2006 to Nov.2008.Result: Five cases died and 2 survived among 7 PE patients.Hemorrhage occurred in 3 out of 403 cases(0.7%),but no PE occurred among 403 patients administered with the LWMH anticoagulant therapy.The incidence of PE in the patients reciving LWMH decreased from 0.9%to 0(P

Objective To assess mucin gene expression in Barrett's esophagus.Methods Mucin core protein-MUC1,MUC2,MUC3,MUCSAC and MUC6 were detected by immunohistochemistry.The re- lationship between mucin expression and magnification-endoscopic characteristics,pathohistologic epithelial types of Barrett's esophagus was analyzed.Results Mild expression of MUC1 was predominantly found in the superficial epithelium of both gastric and specialised intestinal metaplasia.In a small number of specimens, mild expression of MUC1 was also noted in glands.Strong MUC2 expression was noted only in the goblet cells in Barrett's oesophagus.MUC3 was expressed in the superficial columnar cells of specialized intestinal metaplasia with or without globlet cells but not in gastric metaplasia of the oesophagus.In some specimens MUC3 was expressed in the vacuolus of the globlet cells and the lumen of gland.Strong staining of MUCSAC was noted in the columnar epithelium of both gastric metaplasia and specialized intestinal metaplasia in Barrett's oesophagus,as well as expressed in the cytoplasm and vacuolus of the globlet cells in some speci- mens.Expression of MUC6 protein was detected at the basement of the crypts in gastric metaplasia and spe- cialised Barrett's glands.Expression of MUC2 and MUC3 protein was found much higher in villous or irregu- lar pit pattern than that in dot or rod pit pattern(P

Objective To investigate the effects of Tanshinone Ⅱ A (extracted from Chinese herb medicine Salvia miltiorrhiza Bge.) on ventricular arrhythmias of rabbit hearts induced by ischemia in order to illuminate its mechanism of anti-arrhythmia.Methods Thirty rabbits were randomly (random number)divided into normal group,ischemic group and Tanshinone Ⅱ A group.Model of wedge shaped mass of rabbit left ventricular myocardium with coronary perfusion was prepared,and then by using floating glassy microelectrode,the trans-mural ECG,QT interval,the trans-mural dispersion of re-polarization (TDR) and trans-membrane action potentials from both endocardium and epicardium were simultaneously and wholly recorded.The incidence of ventricular arrhythmia in myocardium was observed after ischemia for thirty min.Results Under the condition of acute ischemia,compared with normal group,the incidence of ventricular arrhythmia and TDR were significantly increased in ischemia group (P < 0.01),while incidence of ventricular arrhythmia and TDR were significantly reduced in tanshinone ⅡA group compared with ischemia group (P < 0.05).The incidences of ventricular arrhythmia in normal,ischemia and Tanshinone Ⅱ A groups were 0/10,9/10 and 2/10 respectively.Conclusions Tanshinone Ⅱ A prevents ventricular arrhythmia and reduces TDR significantly in ischemic rabbit hearts.

AIM: To evaluate the effects of the extract of Buddleja officinalis eye drops in basic tears secretory volume, tear film stability, expression of androgen receptors(AR) in castrated rats with dry eye, and to investigate the therapeutic effects of extract of Buddleja officinalis on dry eye caused by gonadal hormones level imbalance. METHODS:A total of 45 Wistar masculinity rats were divided at random into 9 groups, including normal group(A1,A2 and A3), model group(B1,B2 and B3), therapy group with extract of Buddleja officinalis eye drops(C1,C2 and C3). The "1" stood for being fed for 1 month, and "2" for 2 months, and "3" for 3 months. The dry eye model was established with orchiectomy on group B,C. Group C was treated with Buddleja officinalis extract eye drops for one month. All rats were checked with Schirmer Ⅰ test (SⅠt) and tear film break-up time (BUT). Expression of AR was analyzed by flow cytometer(FCM). RESULTS:The SⅠt value of group C was significantly higher than that of group B (P<0.01) and the BUT value of group C was significantly longer than that of group B (P<0.01), which indicated the eye drop could significantly keep basic tears secretory volume and tear film stability. And the expression of AR of group C was much higher than that of group B,which showed that available composition of the eye drops maybe display androgen-like activity.CONCLUSION:The main components of extract of Buddleja officinalis is the flavonoids which could significantly inhibit happening of dry eye of rat after androgen level lowered. Its mechanism is like androgen's and it could display androgen-like activity to keep basic tears secretory volume and tear film stability.

"Wise men could recognize similarities, but the fool only recognizes differences" in Su-wen, which expounded clinical thinking methods of Chinese medicine (CM). "To recognize similarities and differences simultaneously" is of important clinical significance in understanding the laws of diseases. CM pays much attention to recognize similarities, while modern medicine emphasizes the differences observed. In order to develop integrative medicine (IM), similarities recognition and differences identification must be combined together to innovate new thinking methods of IM.

The dynamic changes of germination percentage, germination potential, thousand-seed weight, antioxidase activity in Desmodium styracifolium seeds with different storage time were tested, and electrical conductivity, contents of soluble sugar, soluble protein, starch in seed leach liquor were also determined in order to reveal the mechanism of seed deterioration. The results as the following. (1) The germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds declined, while the seed coat color darkened with the extension of storage time. (2) The activities of superoxide dismutase (SOD) and peroxidase (POD) decreased with the prolongation of storage period. The SOD activity declined fastest in 1,095-1,185 d of storage, while the POD activity declined significantly in 365-395 d of storage. (3) The electrical conductivity and the contents of soluble sugar, starch in seed leach liquor increased, while the content of soluble protein declined with the extension of storage time. (4) Correlation analysis indicated that the germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds have a significantly positive correlation with SOD and POD activity, while have a significantly negative correlation with the electrical conductivity, contents of soluble sugar and starch. It can be concluded that during the storage of D. styracifolium seeds, physiological and biochemical changes including decrease in antioxidase activity, rise in electrical conductivity, degradation effluent of soluble sugar and starch, degradation of soluble protein were the main factors leading to the seed deterioration.
